     Because this is only a summary, it does not contain all the information
that may be important to you. You should read the entire prospectus, especially
"Risk Factors" and the consolidated financial statements and notes, before
deciding to invest in shares of our common stock.

                           PERSISTENCE SOFTWARE, INC.


     Persistence is a leading provider of transactional application server
software products, which move data and processing out of back-end computer
systems and closer to users. Our software supports the Internet infrastructure
that enables the next generation of high-volume, high-performance electronic
commerce applications.



     As the Internet has evolved into a global communications medium, companies
in many industries have begun to extend their business over the Internet to
conduct electronic commerce with customers, suppliers and partners. While
creating new business opportunities, the growth of electronic commerce has also
created tremendous technological challenges. In particular, this growth has
placed stress on the underlying application server infrastructure which
processes these electronic commerce transactions. The first generation of web
application servers that emerged were typically designed to handle simple
information publishing, not to accommodate the high transaction volumes and
performance requirements that characterize electronic commerce today. Even
casual users of the Internet are familiar with the effects of these
infrastructure limitations, such as poor performance and system failures.



     Our PowerTier family of products consists of transactional application
servers specifically designed to enable the next generation of high performance
electronic commerce applications. Our products, PowerTier for EJB and PowerTier
for C++, address the scalability, availability and adaptability problems that
frequently occur when delivering business solutions over the Internet. PowerTier
is one of the few application servers that implements Sun Microsystems' full
Enterprise JavaBeans, or EJB, standard to enable businesses to deploy high
performance, scalable Java applications.



     The PowerTier platform incorporates our patented caching technology, which
speeds transaction processing by moving data and processing out of back-end
computer systems and closer to users. We believe the PowerTier family of
products offers performance that is orders of magnitude faster than traditional
application server software that does not take advantage of caching technology.
Our products offer customers launching sophisticated electronic commerce
applications the following benefits:


     - real-time response times for up to thousands of concurrent users and
       transactions;

     - scalability and reliability to prevent system crashes and downtime;

     - dramatic reductions in time-to-market for building and deploying
       electronic commerce applications;


     - the ability to extend transaction processing across organizational
       boundaries; and


     - support of open Internet standards.

     Our strategy is to provide the leading software platform for the deployment
of high performance electronic commerce applications. Key elements of our
strategy include:

     - capturing additional market share in the emerging business-to-business
       electronic commerce market;


     - extending our technology leadership in standards-based platforms for the
       next generation of electronic commerce;


     - expanding our product platform to offer complementary solutions;

     - increasing our partnerships with systems integrators;
                                        1
<PAGE>   7

     - leveraging our installed customer base; and

     - strengthening our international presence.


     Our customers use PowerTier as the platform for a broad range of electronic
commerce applications, from real-time electronic trading and supply chain
management to Internet network management, application outsourcing and customer
relationship management. We believe our PowerTier products are particularly
well-suited for business-to-business electronic commerce applications requiring
communications among multiple servers in multi-party, multi-step transactions.
Our major customers include AT&T, Boeing, Cisco, FedEx, IBM, Instinet, Lucent,
Morgan Stanley Dean Witter, Norwest, Perkin-Elmer and SuperValu.


     We market and sell our products primarily through a direct sales force in
the United States, United Kingdom and Germany, as well as through distributors.

     Our current stockholders include Cisco, Intel, Reuters and Morgan Stanley
Dean Witter.

     We were incorporated in May 1991 as Fulcrum Innovations, Inc. and
subsequently changed our name to Persistence Software, Inc. Our principal
executive offices are located at 1720 South Amphlett Blvd., Third Floor, San
Mateo, California 94402. Our telephone number at that location is (650)

     See notes 1 and 6 of notes to consolidated financial statements for an
explanation of the method used to determine the number of shares used to compute
the net loss per share and pro forma net loss per share amounts.

     The pro forma column in the consolidated balance sheet data reflects the
automatic conversion of each outstanding share of preferred stock into one share
of common stock immediately before the completion of the offering.


     The pro forma as adjusted numbers in the table above are adjusted to give
effect to receipt of the net proceeds from the sale of shares of common stock
offered by us at an assumed offering price of $10.00 per share after deducting
the estimated underwriting discounts and commissions and estimated offering
expenses payable by us.



     Except as otherwise indicated, all information in this prospectus is based
on the following assumptions: (a) the conversion of each outstanding share of
preferred stock into one share of common stock immediately before the completion
of this offering, (b) no exercise of the underwriters' overallotment option, (c)
our reincorporation in Delaware before the effectiveness of this offering and
(d) the filing of our amended and restated certificate of incorporation upon
completion of this offering.

                                  RISK FACTORS

     You should carefully consider the following risks in addition to the
remainder of this prospectus before purchasing our common stock. The risks and
uncertainties described below are intended to be the ones that are specific to
our company and are not the only ones that we face. Additional risks and
uncertainties that generally apply to businesses in our industry or to companies
that are going public may also impair our business.


WE HAVE A LIMITED OPERATING HISTORY IN THE APPLICATION SERVER MARKET.


     Because we only commenced selling application servers in 1997, we have a
limited operating history in the application server market. You should consider
our prospectus in light of the risks, expenses and difficulties frequently
encountered by companies in early stages of development, particularly companies
in the rapidly changing software industry. These risks include:

     - our substantial dependence for revenue from our PowerTier for C++
       product, which was first introduced in 1997 and has achieved only limited
       market acceptance;

     - our need to successfully sell our PowerTier for EJB product, which was
       first introduced in 1998 and has achieved only limited market acceptance;

     - our need to expand our distribution capability through both a direct
       sales organization and third party distributors and systems integrators;

     - our unproven ability to anticipate and respond to technological and
       competitive developments in the rapidly changing market for application
       servers;

     - our unproven ability to compete in a highly competitive market;


     - uncertainty as to the growth rate in the electronic commerce market and,
       in particular, the business-to-business electronic commerce market;


     - our dependence on Enterprise JavaBeans, commonly known as EJB, becoming a
       widely accepted standard in the transactional application server market;
       and

     - our dependence upon key personnel.


BECAUSE WE HAVE A HISTORY OF LOSSES, WE MAY NEVER BECOME OR REMAIN PROFITABLE.



     Our revenues may not continue to grow and we may not be able to achieve or
maintain profitability in the future. We have incurred net losses each year
since 1996. In particular, we incurred losses of $3.3 million in 1996, $4.7
million in 1997, $4.1 million in 1998 and $1.9 million in the three months ended
March 31, 1999. As of March 31, 1999, we had an accumulated deficit of
approximately $14.7 million. In addition, while we are unable to predict
accurately our future product development, sales and marketing and
administrative expenses, we currently expect these expenses to increase. Thus,
we will need to increase our revenues to become profitable. Because our product
market is new and evolving, we cannot accurately predict either the future
growth rate, if any, or the ultimate size of the market for our products.



WE HAVE FINANCED OUR BUSINESS THROUGH THE SALE OF STOCK, AND WE MAY NEED TO
RAISE ADDITIONAL CAPITAL IN THE FUTURE.



     Since inception, we have generally had negative cash flow from operations
and have financed our business primarily through private sales of preferred
stock. We expect to


                                        4
<PAGE>   10


continue to have negative cash flow from operations for the next several
quarters. Although we believe that the net proceeds from this offering, together
with our current cash balances, will be sufficient to meet our anticipated
operating cash needs for the next 18 months, we may need to raise additional
funds prior to that time. If we raise additional funds through the issuance of
debt securities, these securities would probably have rights senior to the
common stock. In addition, the sale of additional equity or convertible debt
securities could result in additional dilution to our stockholders, and we may
not be able to obtain additional financing on acceptable terms, if at all. Any
failure to obtain additional financing could require us to reduce the scope of
our planned product development or marketing efforts.


THE UNPREDICTABILITY OF OUR QUARTERLY RESULTS MAY ADVERSELY AFFECT THE PRICE OF
OUR COMMON STOCK.


     Our operating results have fluctuated significantly in the past and may
fluctuate significantly in the future as a result of a variety of factors, many
of which are outside our control. In particular, the fourth quarter of each year
has in the past tended to account for the greatest percentage of total revenues
for the year, and we have often experienced an absolute decline in revenues from
the fourth quarter to the first quarter of the next year. If our future
quarterly operating results are below the expectations of securities analysts or
investors, the price of our common stock would likely decline. The factors that
may cause fluctuations of our operating results include the following:


     - our ability to close relatively large sales on schedule;

     - delays or deferrals of customer orders or deployments;

     - delays in shipment of scheduled software releases;

     - demand for and market acceptance of our PowerTier for C++ and PowerTier
       for EJB products;

     - the possible loss of sales people;

     - introduction of new products or services by us or our competitors;

     - annual or quarterly budget cycles of our customers;

     - the level of product and price competition in the application server
       market;

     - our lengthy sales cycle;

     - our success in expanding our direct sales force and indirect distribution
       channels;

     - the mix of direct sales versus indirect distribution channel sales;

     - the mix of products and services licensed or sold;

     - the mix of domestic and international sales; and


     - our success in penetrating international markets and general economic
       conditions in these markets.


     We typically receive a substantial portion of our orders in the last two
weeks of each fiscal quarter because our customers often delay purchases of our
products to the end of the quarter to gain price concessions. Because a
substantial portion of our costs are relatively fixed and based on anticipated
revenues, a failure to book an expected order in a given quarter would not be
offset by a corresponding reduction in costs and could adversely affect our
operating results.

                                        5
<PAGE>   11

OUR SALES CYCLE IS LONG, UNPREDICTABLE AND SUBJECT TO SEASONAL FLUCTUATIONS, SO
IT IS DIFFICULT TO FORECAST OUR REVENUES.

     Any delay in sales of our products or services could cause our quarterly
revenues and operating results to fluctuate. The typical sales cycle of our
products is long and unpredictable and requires both a significant capital
investment decision by our customers and our education of potential customers
regarding the use and benefits of our products. Our sales cycle is generally
between three and nine months. A successful sales cycle typically includes
presentations to both business and technical decision makers, as well as a
limited pilot program to establish technical fit. Our products typically are
purchased as part of a significant enhancement to a customer's information
technology system. The implementation of our products involves a significant
commitment of resources by prospective customers. Accordingly, a purchase
decision for a potential customer typically requires the approval of several
senior decision makers. Our sales cycle is affected by the business conditions
of each prospective customer. Due to the relative importance of many of our
product sales, a lost or delayed sale could adversely affect our quarterly
operating results. Our sales cycle is affected by seasonal fluctuations as a
result of our customers' fiscal year budgeting cycles and slow summer purchasing
patterns in Europe. Also, our revenues are typically higher in the fourth
quarter than in other quarters of the year.

WE DEPEND ON A RELATIVELY SMALL NUMBER OF SIGNIFICANT CUSTOMERS, AND THE LOSS OF
ONE OR MORE OF THESE CUSTOMERS COULD RESULT IN A DECREASE IN OUR REVENUES.


     Historically, we have received a substantial portion of our revenues from
product sales to a limited number of customers. In 1998, sales of products and
services to Cisco accounted for 14% of our total revenues, sales of products and
services to Instinet accounted for 17% of our total revenues, and sales of
products and services to our top five customers accounted for 55% of total
revenues. In 1997, sales of products and services to Lucent accounted for 11% of
our total revenues, and sales of products and services to our top five customers
accounted for 15% of our total revenues. In addition, the identity of our top
five customers has changed from year to year. If we lose a significant customer,
or fail to increase product sales to an existing customer as planned, we may not
be able to replace the lost revenues with sales to other customers. In addition,
because our marketing strategy is to concentrate on selling products to industry
leaders, any loss of a customer could harm our reputation within the industry
and make it harder for us to sell our products to other companies in that
industry. The loss of, or a reduction in sales to, one or more significant
customers would likely result in a decrease in our revenues.


WE DEPEND ON THE JAVA PROGRAMMING LANGUAGE, THE ENTERPRISE JAVABEANS STANDARD
AND THE EMERGING MARKET FOR DISTRIBUTED OBJECT COMPUTING, AND IF THESE
TECHNOLOGIES FAIL TO GAIN ACCEPTANCE, OUR BUSINESS COULD SUFFER.


     We are focusing significant marketing efforts on our PowerTier for EJB
application server, which is based on three relatively new technologies, none of
which have been widely adopted by companies. These three technologies are a
distributed object computing architecture, Sun Microsystems' Java programming
language and Enterprise JavaBeans, or EJB. Distributed object computing combines
the use of software modules, or objects, communicating across a computer network
to software applications, such as our PowerTier application server. EJB is the
Java programming standard for use in an application server. In 1998, we launched
our PowerTier for EJB product, which is a transactional application server that
uses Java and conforms to the EJB standard. Sun Microsystems released the EJB
standard in 1998, and thus far EJB has had limited market acceptance. We expect
a


                                        6
<PAGE>   12

substantial portion of our future revenues will come from sales of products
based on the EJB standard. Thus, our success depends significantly upon broad
market acceptance of distributed object computing in general, and Java
application servers in particular. If EJB does not become a widespread
programming standard for application servers, our revenues and business could
suffer.


IF WE DO NOT DELIVER PRODUCTS THAT MEET RAPIDLY CHANGING TECHNOLOGY STANDARDS
AND CUSTOMER DEMANDS, WE WILL LOSE MARKET SHARE TO OUR COMPETITORS.


     The market for our products and services is characterized by rapid
technological change, dynamic customer demands and frequent new product
introductions and enhancements. Customer requirements for products can change
rapidly as a result of innovation in software applications and hardware
configurations and the emergence or adoption of new industry standards,
including Internet technology standards. We need to increase our research and
development investment to maintain our technological leadership. Our future
success depends on our ability to continue to enhance our current products and
to continue to develop and introduce new products that keep pace with
competitive product introductions and technological developments. For example,
as Sun Microsystems introduces new EJB specifications, we will need to introduce
new versions of PowerTier for EJB designed to support these new specifications
to remain competitive. If we do not bring enhancements and new versions of our
products to market in a timely manner, our market share and revenues could
decrease and our reputation could suffer. If we fail to anticipate or respond
adequately to changes in technology and customer needs, or if there are any
significant delays in product development or introduction, our revenues and
business could suffer.


BECAUSE OUR DIRECT SALES TEAM IS CURRENTLY OUR MOST CRITICAL SALES CHANNEL, ANY
FAILURE TO BUILD AND TRAIN THIS TEAM MAY RESULT IN LOWER REVENUES.



     We must expand our direct sales team to generate increased revenue. In
1998, we hired several new salespeople, replacing most of our preexisting sales
force. In order to meet our future sales goals, we will need to hire many more
salespeople within the next two years for both our domestic and international
sales efforts. In the past, newly hired employees have required training and
approximately six to nine months experience to achieve full productivity.
Because our entire sales team is relatively new, we cannot be certain that they
will meet our sales goals. In addition, our recently hired employees may not
become productive, and we may not be able to hire enough qualified individuals
in the future.



BECAUSE OUR FUTURE REVENUE GOALS ARE BASED ON OUR DEVELOPMENT OF A STRONG SALES
CHANNEL THROUGH SYSTEMS INTEGRATORS AND OTHER THIRD PARTIES, ANY FAILURE TO
DEVELOP THIS CHANNEL MAY RESULT IN LOWER REVENUES.


     To date, we have sold our products primarily through our direct sales
force, but our ability to achieve significant revenue growth in the future will
depend in large part on our success in establishing and leveraging relationships
with systems integrators and other third parties. It may be difficult for us to
establish these relationships, and, even if we establish these relationships, we
will then depend on the systems integrators' and other third parties' sales
efforts. In addition, because these relationships are nonexclusive, systems
integrators may choose to use application servers or other alternative solutions
offered by our competitors, and not our products. If we fail to successfully
build our third-party

                                        7
<PAGE>   13

distribution channels or if our systems integrator and other third party
partners do not perform as expected, our business could be harmed.


BECAUSE OUR PRODUCTS ARE OFTEN INCORPORATED INTO ENTERPRISE-WIDE SYSTEM
DEPLOYMENTS, ANY DELAYS IN THESE PROJECTS MAY RESULT IN LOWER REVENUES.



     Because our products are often incorporated into multi-million dollar
enterprise projects, we depend on the successful and timely completion of these
enormous projects to fully deploy our products and achieve our revenue goals.
These enterprise projects often take many years to complete and can be delayed
by a variety of factors, including general or industry-specific economic
downturns, our customers' budget constraints, year 2000 problems or other
customer-specific delays, problems with other system components or delays caused
by the systems integrators who may be managing the system deployment. If our
customers cannot successfully implement large-scale deployments, or they
determine for any reason that our products cannot accommodate large-scale
deployments or that our products are not appropriate for widespread use, our
business could suffer. In addition, if a systems integrator fails to complete a
project utilizing our product for a customer in a timely manner, our revenues or
business reputation could suffer.


BECAUSE WE COMPETE WITH SUN MICROSYSTEMS, WHO CONTROLS THE EJB APPLICATION
SERVER STANDARD, WE FACE THE RISK THAT THEY MAY DEVELOP THIS STANDARD TO FAVOR
THEIR OWN PRODUCTS.


     Our success depends on achieving widespread market acceptance of our
PowerTier for EJB application server. Because Sun Microsystems controls the EJB
standard, we need to maintain a good working relationship with Sun Microsystems
to develop future versions of PowerTier for EJB, as well as additional products
using EJB, that will gain market acceptance. In March 1998, we entered into a
license agreement with Sun Microsystems, pursuant to which we granted Sun
Microsystems rights to manufacture and sell, by itself and not jointly with
others, products under a number of our patents and Sun Microsystems granted us
rights to manufacture and sell, by ourselves and not jointly with others,
products under a number of Sun Microsystems' patents. As a result, Sun
Microsystems may develop and sell some competing products that would, in the
absence of this license agreement, infringe our patents. Because Sun
Microsystems controls the EJB standard, it could develop the EJB standard in a
more proprietary way to favor a product offered by one of its subsidiaries,
NetDynamics or KIVA Software, or a third party, which could make it much harder
for us to compete in the EJB application server market.


MICROSOFT HAS ESTABLISHED A COMPETING APPLICATION SERVER STANDARD, WHICH COULD
DIMINISH THE MARKET POTENTIAL FOR OUR PRODUCTS IF IT GAINS WIDESPREAD
ACCEPTANCE.


     Microsoft has established a competing standard for distributed computing,
COM, which includes an application server product. If this standard gains
widespread market acceptance over the EJB or CORBA standards, on which our
products are based, our business would suffer. Because of Microsoft's resources
and commanding position with respect to other markets and technologies,
Microsoft's entry into the application server market may cause our potential
customers to delay purchasing decisions. We expect that Microsoft's presence in
the application server market will increase competitive pressure in this market.


                                        8
<PAGE>   14

WE FACE SIGNIFICANT COMPETITION FROM COMPANIES WITH GREATER RESOURCES THAN WE
HAVE AND MAY FACE ADDITIONAL COMPETITION IN THE FUTURE.

     The market for our products is intensely competitive, subject to rapid
change and significantly affected by new product introductions and other market
activities of industry participants. We believe that the principal competitive
factors in our market are:

     - performance, including scalability, integrity and availability;

     - ability to provide a complete software platform;

     - flexibility;

     - use of standards-based technology;

     - ease of integration with customers' existing enterprise systems;

     - quality of support and service;

     - security;

     - company reputation; and

     - price.


     Our competitors include both publicly and privately-held enterprises,
including BEA Systems (WebLogic), Gemstone Systems, IBM (WebSphere), Inprise,
Iona Technologies, Oracle (OAS) and Sun Microsystems (NetDynamics). Many
customers may not be willing to purchase our PowerTier platform because they
have already invested heavily in databases and other enterprise software
components offered by these competing companies. Many of these competitors have
preexisting customer relationships, longer operating histories, greater
financial, technical, marketing and other resources, greater name recognition
and larger installed bases of customers than we do. Moreover, there are other
very large and established companies, including Microsoft and Netscape, who
offer alternative solutions and are thus indirect competitors. Further, dozens
of companies have announced their intention to support EJB and may compete
against us in the future. These competitors and potential competitors may be
able to respond more quickly to new or emerging technologies and changes in
customer requirements, or to devote greater resources to the development,
promotion and sale of their products than we can. In addition, in the PowerTier
for C++ market, many potential customers build their own custom application
servers, so we effectively compete against our potential customers' internal
information technology departments.



IF THE MARKET FOR BUSINESS-TO-BUSINESS ELECTRONIC COMMERCE OVER THE INTERNET
DOES NOT DEVELOP AS WE CURRENTLY ENVISION, OUR BUSINESS MODEL COULD FAIL AND OUR
REVENUES COULD DECLINE.



     Our performance and future success will depend on the growth and widespread
adoption of the market for business-to-business electronic commerce over the
Internet. If business-to-business electronic commerce does not develop in the
manner currently envisioned, our business could be materially and adversely
affected. Moreover, critical issues concerning the commercial use of the
Internet, including security, cost, accessibility and quality of network
service, remain unresolved and may negatively affect the growth of the Internet
as a platform for conducting business-to-business electronic commerce. In
addition, the Internet could lose its viability due to delays in the development
or adoption of new standards and protocols to handle increased activity or due
to increased government regulation and taxation of Internet commerce.

OUR FAILURE TO MANAGE GROWTH COULD IMPAIR OUR BUSINESS.

     Achieving our planned revenue growth and other financial objectives will
place significant demands on our management and other resources. We anticipate
increasing our headcount significantly over the next two years. Our ability to
manage this growth effectively will require us to continue to develop and
improve our operational, financial and other internal systems and controls, as
well as our business development capabilities, and to train, motivate and manage
our employees. If we are unable to manage our growth effectively, we may not be
able to retain key personnel and the quality of our services and products may
suffer.

OUR BUSINESS COULD SUFFER IF WE CANNOT ATTRACT AND RETAIN THE SERVICES OF KEY
EMPLOYEES.


     Our future success depends on the ability of our management to operate
effectively, both individually and as a group. We are substantially dependent
upon the continued service of our existing executive personnel, especially
Christopher T. Keene, our Chief Executive Officer and Chairman of the Board. We
do not have a key person life insurance policy covering Mr. Keene or any other
officer or key employee. Our success will depend in large part upon our ability
to attract and retain highly-skilled employees, particularly sales personnel and
software engineers. There is significant competition for skilled employees,
especially for people who have experience in both the software and Internet
industries. If we are not successful in attracting and retaining these skilled
employees, our sales and product development efforts would suffer. In addition,
if one or more of our key employees resigns to join a competitor or to form a
competing company, the loss of that employee and any resulting loss of existing
or potential customers to a competitor could harm our business. If we lose any
key personnel, we may not be able to prevent the unauthorized disclosure or use
of our technical knowledge or other trade secrets by those former employees.


OUR SOFTWARE PRODUCTS MAY CONTAIN DEFECTS OR ERRORS, AND SHIPMENTS OF OUR
SOFTWARE MAY BE DELAYED.

     Complex software products often contain errors or defects, particularly
when first introduced or when new versions or enhancements are released. Our
products have in the past contained and may in the future contain errors and
defects, which may be serious or difficult to correct and which may cause delays
in subsequent product releases. Delays in shipment of scheduled software
releases or serious defects or errors could result in lost revenues or a delay
in market acceptance, which could have a material adverse effect on our revenues
and reputation.

WE MAY BE SUED BY OUR CUSTOMERS FOR PRODUCT LIABILITY CLAIMS AS A RESULT OF
FAILURES IN THEIR CRITICAL BUSINESS SYSTEMS.


     Because our customers use our products for important business applications,
errors, defects or other performance problems could result in financial or other
damages to our customers. They could pursue claims for damages, which, if
successful, could result in our having to make substantial payments. Although
our purchase agreements typically contain provisions designed to limit our
exposure to product liability claims, existing or future laws or unfavorable
judicial decisions could negate these limitation of liability provisions. A
product liability claim brought against us, even if meritless, would likely be
time consuming and costly for us to litigate or settle.

A SIGNIFICANT PORTION OF OUR REVENUES IS DERIVED FROM INTERNATIONAL SALES, WHICH
COULD DECLINE AS A RESULT OF LEGAL, BUSINESS AND ECONOMIC RISKS SPECIFIC TO
INTERNATIONAL OPERATIONS.



     Our future success will depend, in part, on our successful development of
international markets for our products. Approximately 29% of our revenues came
from sales of products and services outside the United States in the year ended
December 31, 1998. Approximately 22% of our revenues came from sales of products
and services outside the United States during the three months ended March 31,
1999. We expect international revenues to continue to represent a significant
portion of our total revenues. To date, almost all of our international revenues
have resulted from our direct sales efforts. In international markets, however,
we expect that we will depend more heavily on third party distributors to sell
our products in the future. The success of our international strategy will
depend on our ability to develop and maintain productive relationships with
these third parties. The failure to develop key international markets for our
products could cause a reduction in our revenues. Additional risks related to
our international expansion and operation include:


     - difficulties of staffing and managing foreign operations;

     - our dependence on the sales efforts of our third party distributors;

     - longer payment cycles typically associated with international sales;

     - tariffs and other trade barriers;

     - failure to comply with a wide variety of complex foreign laws and
       changing regulations;

     - exposure to political instability and economic downturns;

     - failure to localize our products for foreign markets;

     - restrictions on the export of technologies;

     - potentially adverse tax consequences;

     - reduced protection of intellectual property rights in some countries; and

     - currency fluctuations.

     We sell products outside the United States in U.S. dollars. We do not
currently engage in any hedging transactions to reduce our exposure to currency
fluctuations as a result of our foreign operations. We are not currently ISO
9000 compliant, nor are we attempting to meet all foreign technical standards
that may apply to our products. Our failure to develop our international sales
channel as planned could cause a decline in our revenues.

IF WE DO NOT PROTECT OUR INTELLECTUAL PROPERTY RIGHTS, OUR COMPETITIVE POSITION
MAY BE IMPAIRED.

     Our success may depend on our ability to protect our proprietary rights to
the technologies used in our products, and yet the measures we are taking to
protect these rights may not be adequate. If we are not adequately protected,
our competitors could use the intellectual property that we have developed to
enhance their products, which could harm our business. We rely on patent
protection, as well as a combination of copyright, trade secret and trademark
laws, and nondisclosure and other contractual restrictions to protect our
proprietary technology, but these legal means afford only limited protection.

                                       11
<PAGE>   17

Unauthorized parties may attempt to copy aspects of our products or to obtain
and use information that we regard as proprietary. In addition, the laws of some
foreign countries may not protect our intellectual property rights to the same
extent as do the laws of the United States. Further, litigation may be necessary
to enforce our intellectual property rights, which could result in substantial
costs and diversion of management attention and resources.

WE MAY BE SUED FOR VIOLATING THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS.


     The software industry is characterized by the existence of a large number
of patents and frequent litigation based on allegations of patent infringement
and the violation of other intellectual property rights. As the number of
competitors in the application server market grows and the functionality of
products in different market segments overlaps, the possibility of an
intellectual property claim against us increases. For example, we may
inadvertently infringe a patent of which we are unaware. In addition, because
patent applications can take many years to issue, there may be a patent
application now pending of which we are unaware, which will cause us to be
infringing when it is issued in the future. To address these patent infringement
or other intellectual property claims, we may have to enter into royalty or
licensing agreements on disadvantageous commercial terms. Alternatively, we may
be unable to obtain a necessary license. A successful claim against us, and our
failure to license the infringed or similar technology, would harm our business.
In addition, any infringement or other intellectual property claims, with or
without merit, which are brought against us could be time consuming and
expensive to litigate or settle and could divert management attention from
administering our core business.


WE FACE RISKS ASSOCIATED WITH THE YEAR 2000 ISSUE, INCLUDING THE RISK THAT OUR
PRODUCTS OR INTERNAL SYSTEMS MAY NOT BE YEAR 2000 COMPLIANT AND THE RISK THAT
OUR CUSTOMERS MAY DELAY THE PURCHASE OF OUR POWERTIER PLATFORM AS A RESULT OF
THEIR OWN YEAR 2000 CONCERNS.

     We have designed and tested the most current versions of our products to be
year 2000 compliant. However, we have not tested our products on all platforms
or all versions of operating systems that we currently support. Despite this
testing, our products may contain undetected errors or defects associated with
year 2000 date functions that may be expensive for us to remedy. Because our
products are generally incorporated into a large enterprise-wide system
enhancement, we may face claims based on year 2000 issues arising from the
integration of multiple products, including ours, within an overall system. Some
commentators have stated that a significant amount of litigation will arise out
of year 2000 issues, and we are aware of a growing number of lawsuits against
other software vendors.

     We may experience serious unanticipated problems and material costs caused
by undetected errors or defects in the technology used in our internal systems
relating to the year 2000 transition. These systems include the hardware and
third-party software products that our research and development staff use in
their daily activities, as well as our management information systems. The most
likely worst case scenarios include:

     - hardware or software failures that would prevent our research and
       development staff from effectively performing their duties;

     - corruption of data contained in our internal information systems; and

     - the failure of infrastructure services provided by government agencies
       and other third parties, including public utilities and Internet service
       providers.

                                       12
<PAGE>   18

     Finally, our potential customers may cease or delay the purchase and
installation of new complex systems, such as systems incorporating our PowerTier
application server, or may defer an enterprise-wide deployment of our PowerTier
platform, as a result of, and during, their own internal year 2000 testing. Any
resulting delay or decrease in orders for our products could cause our revenues
to decline, either on a quarterly or absolute basis. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations -- Year
2000 Compliance."

FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE.


     If our current stockholders sell substantial amounts of common stock,
including shares issued upon the exercise of outstanding options and warrants,
in the public market, the market price of our common stock could fall. In
addition, these sales of common stock after the offering could impede our
ability to raise funds at an advantageous price through the sale of securities.
After this offering, we will have outstanding 18,447,941 shares of common stock.
The 3,000,000 shares sold in this offering will be immediately available for
sale in the public market. Beginning 90 days after the effective date of this
prospectus, approximately 147,790 shares will be eligible for sale. Beginning
180 days after the effective date, approximately 14,434,150 shares will be
eligible for sale, 7,014,673 of which will be subject to volume and other
restrictions under Rule 144. The remaining 866,001 shares will be eligible for
sale upon the expiration of various one-year holding periods during the six
months following 180 days after the effective date, subject to volume and other
restrictions under Rule 144.


OUR STOCK PRICE MAY BE VOLATILE.

     Before this offering, there has been no public market for our common stock.
An active public market for our common stock may not develop or be sustained
after this offering. If you purchase shares in this offering, you will pay a
price that was not established in a competitive market, but was rather a price
that we negotiated with the underwriters. After the offering, the market price
of our common stock is likely to be highly volatile and may rise or fall as a
result of many factors, such as:

     - variations in our quarterly results;

     - announcements of technological innovations by us or our competitors;

     - introductions of new products by us or our competitors;

     - acquisitions or strategic alliances by us or our competitors;

     - hiring or departure of key personnel;

     - the gain or loss of a significant customer or order;

     - changes in estimates of our financial performance or changes in
       recommendations by securities analysts;

     - market conditions in the software industry and in our customers'
       industries; and

     - adoption of new accounting standards affecting the software industry.

     The stock market in general has experienced extreme price and volume
fluctuations, which could adversely affect the market price of our stock. In
particular, the market prices of the common stock of many companies in the
software and Internet industries have experienced this volatility, which has
often been unrelated to these companies' operating performance. In the past,
securities class action litigation has often been brought against a

                                       13
<PAGE>   19

company after a period of volatility in the market price of its stock. We may in
the future be a target of similar litigation. Securities litigation could result
in substantial costs and divert management's attention and resources, which
could harm our business.


OUR EXECUTIVE OFFICERS AND DIRECTORS OWN A LARGE PERCENTAGE OF OUR VOTING STOCK
AND COULD EXERT SIGNIFICANT INFLUENCE OVER MATTERS REQUIRING STOCKHOLDER
APPROVAL AFTER THIS OFFERING.



     Immediately after this offering, our executive officers and directors, and
entities affiliated with them, will continue to own approximately 60% of our
outstanding common stock. Accordingly, these stockholders may, as a practical
matter, continue to control the election of a majority of the directors and the
determination of all corporate actions after this offering. This concentration
of voting control could have the effect of delaying or preventing a merger or
other change in control, even if it would benefit our other stockholders.


THE ANTITAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND UNDER DELAWARE LAW
COULD DISCOURAGE A TAKEOVER.


     Provisions in our certificate of incorporation, bylaws and Delaware law may
discourage, delay or prevent a merger or other change in control that a
stockholder may consider favorable. These provisions may also discourage proxy
contests or make it more difficult for stockholders to take corporate action.
These provisions include the following:


     - establishing a classified board in which only a portion of the total
       board members will be elected at each annual meeting;

     - authorizing the board to issue preferred stock;

     - prohibiting cumulative voting in the election of directors;

     - 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 of
       the board of directors or for proposing matters that can be acted on by
       stockholders at stockholder meetings.

     See "Management -- Board Composition" and "Description of Capital Stock --
Delaware Antitakeover Law and Provisions of our Certificate of Incorporation and
Bylaws."

WE MAY ENGAGE IN FUTURE ACQUISITIONS THAT COULD DISRUPT OUR BUSINESS AND DILUTE
OUR STOCKHOLDERS.

     As part of our business strategy, we expect to review acquisition prospects
that we believe would be advantageous to the development of our business. For
example, we expect to expand our PowerTier platform to include object request
broker technology. While we have no current agreements or negotiations underway
with respect to any major acquisitions, we may make acquisitions of businesses,
products or technologies in the future. If we make any acquisitions, we could
take any or all of the following actions, any of which could materially and
adversely affect our financial results and the price of our common stock:

     - issue equity securities that would dilute existing stockholders'
       percentage ownership;

     - incur substantial debt;

                                       14
<PAGE>   20

     - assume contingent liabilities; or

     - take substantial charges in connection with the amortization of goodwill
       and other intangible assets.

     Acquisitions also entail numerous risks, including:

     - difficulties in assimilating acquired operations, products and personnel
       with our pre-existing business;

     - unanticipated costs;

     - diversion of management's attention from other business concerns;

     - adverse effects on existing business relationships with suppliers and
       customers;

     - risks of entering markets in which we have limited or no prior
       experience; and

     - potential loss of key employees from either our preexisting business or
       the acquired organization.

     We may not be able to successfully integrate any businesses, products,
technologies or personnel that we might acquire in the future, and our failure
to do so could harm our business.


YOU WILL PAY SUBSTANTIALLY MORE FOR YOUR SHARES THAN THE NET TANGIBLE BOOK VALUE
PER SHARE OF THE SHARES YOU ACQUIRE.



     If you purchase shares of common stock in this offering, you could pay as
much as $11.00 per share, which substantially exceeds $0.41, which is the net
tangible book value per share of the shares you would acquire. Assuming that the
offering price is $10.00, the stockholders who purchase shares in this offering
will contribute 60% of the total amount of our funding to date, but will only
own a total of 16% of our shares outstanding. This dilution is in large part
because our earlier investors paid substantially less than the public offering
price when they purchased their shares of common stock. You will experience
additional dilution upon the exercise of outstanding stock options or warrants
to purchase common stock.



WE HAVE NOT DESIGNATED ANY SPECIFIC USE FOR THE NET PROCEEDS OF THIS OFFERING,
AND THUS MAY USE THE PROCEEDS TO FUND OPERATING LOSSES, FOR ACQUISITIONS OR FOR
OTHER CORPORATE PURPOSES.



     We have not designated any specific use for the net proceeds of this
offering. As a result, our management and board of directors will have broad
discretion in spending the proceeds of this offering. We currently expect to use
the net proceeds primarily for working capital and general corporate purposes,
funding product development and expanding our sales and marketing organization.
In addition, we may use a portion of the net proceeds for further development of
our product lines through acquisitions of products, technologies and businesses.

               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 are forward-looking
statements. These statements relate to future events or our future financial
performance, and 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 these
forward-looking statements.

     In some cases, you can identify forward-looking statements by words such as
"may," "will," "should," "expects," "plans," "anticipates," "believes,"
"estimates," "predicts," "potential" or "continue," or the negative of these and
other similar words.


     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 forward-looking
statements. We are under no duty to update any of the forward-looking statements
after the date of this prospectus to conform these statements to actual results.

<PAGE>   22

                                USE OF PROCEEDS


     Our net proceeds from the sale of the 3,000,000 shares of common stock we
are offering are estimated to be $27,000,000 ($31,185,000 if the underwriters'
over-allotment option is exercised in full), assuming an initial public offering
price of $10.00 per share, after deducting the estimated underwriting discount
and commissions and the estimated offering expenses.


     We currently expect to use the net proceeds primarily for working capital
and general corporate purposes, funding product development and expanding our
sales and marketing organization. In addition, we may use a portion of the net
proceeds for further development of our product lines through acquisitions of
products, technologies and businesses, although we have no present commitments
or agreements to make any major acquisitions. The amount of cash that we
actually expend for working capital purposes will vary significantly depending
on a number of factors, including future revenue growth, if any, and the amount
of cash we generate from operations. Thus, management will have significant
discretion in applying the net proceeds of this offering. Pending the uses
described above, we will invest the net proceeds in short-term, investment
grade, interest-bearing securities.

                                DIVIDEND POLICY

     We have never paid dividends on our common stock or preferred stock. We
currently intend to retain any future earnings to fund the development of our
business. Therefore, we do not currently anticipate declaring or paying
dividends in the foreseeable future. In addition, our line of credit agreement
prohibits us from paying dividends.

       of shares of common stock at an assumed initial public offering price of
       $10.00 per share in this offering, after deducting the estimated
       underwriting discounts and commissions and estimated offering expenses
       that Persistence expects to pay in connection with this offering; and


     - the authorization of 75,000,000 shares of common stock and 5,000,000

                                    DILUTION


     The pro forma net tangible book value on March 31, 1999 was $6,309,000, or
$0.41 per share of common stock. Pro forma net tangible book value per share
represents the amount of our total tangible assets less total liabilities,
divided by the number of shares of common stock outstanding, after giving effect
to the conversion of all outstanding shares of preferred stock into common stock
immediately prior to the closing of this offering. Dilution in net tangible book
value per share represents the difference between the amount per share paid by
purchasers of shares of our common stock in this offering and the net tangible
book value per share of our common stock immediately following this offering.
After giving effect to our sale of shares of common stock in this offering and
after deducting the estimated underwriting discount and commissions and our
estimated offering expenses, our pro forma net tangible book value as of March
31, 1999 would have been $33,309,000 or $1.81 per share of common stock. This
represents an immediate increase in net tangible book value of $1.40 per share
to existing stockholders and an immediate dilution of $8.19 per share to new
investors. The following table illustrates this per share dilution:

     The following selected consolidated financial data should be read in
conjunction with the Consolidated Financial Statements and Notes thereto and
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations," which are included elsewhere in this prospectus. The consolidated
statements of operations data for the years ended December 31, 1996, 1997 and
1998, and the consolidated balance sheet data at December 31, 1997 and 1998, are
derived from audited consolidated financial statements included elsewhere in
this prospectus. The consolidated statements of operations data for the years
ended December 31, 1994 and 1995, and the consolidated balance sheet data as of
December 31, 1994, 1995 and 1996 are derived from audited financial statements
not included in this prospectus. The consolidated statements of operations data
for the three-months ended March 31, 1998 and 1999 and the consolidated balance
sheet data as of March 31, 1999 are derived from unaudited consolidated
financial statements included elsewhere in this prospectus. In our opinion,
these unaudited statements include all adjustments, consisting of normal

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


     This section of our prospectus includes a number of forward-looking
statements that reflect our current views with respect to future events and
financial performance. We use words such as "anticipates," "believes,"
"expects," "future," "intends" and similar expressions to identify
forward-looking statements. You should not place undue reliance on these
forward-looking statements, which apply only as of the date of this prospectus.
These forward-looking statements are subject to risks and uncertainties that
could cause actual results to differ materially from historical results or our
predictions. For a description of these risks, see "Risk Factors."


OVERVIEW

     We are a leading provider of transactional application server software
products that comprise the Internet software infrastructure for high volume,
high performance electronic commerce applications. We were incorporated and
began operations in 1991. Our first products incorporated patented
object-to-relational mapping and caching technologies, which have since become
the foundation for our PowerTier product family. From 1992 to 1996, we
introduced a variety of enhancements to these products, including a patented
data transformation technology for mapping objects to database tables, and
caching capabilities.

     In 1996, we developed our PowerTier transactional application server, which
integrates all of these previously released Persistence products with new shared
transactional caching technologies, which enable multiple users to
simultaneously access the same cached data. We first shipped our PowerTier for
C++ transactional application server in 1997. Sales of PowerTier for C++
accounted for the majority of our revenues in 1997 and 1998, during which years
we added a professional services staff to enable our customers to implement
PowerTier more rapidly. We were one of the first companies to adopt and
implement the EJB specification. In 1998, we introduced PowerTier for EJB, which
customers have frequently purchased together with PowerTier for C++. Our next
version of PowerTier for EJB is currently in use by several major customers and
is expected to be commercially released later in 1999. We currently plan to
continue to focus product development efforts on enhancements to both the
PowerTier for C++ and the PowerTier for EJB products.


     Our revenues, which consist of software license revenues and service
revenues, totaled $3.8 million in 1996, $5.4 million in 1997, $10.2 million in
1998 and $2.9 million in the three months ended March 31, 1999. License revenues
consist of licenses of our software products, which generally are priced based
on the number of users or servers. Service revenues consist of professional
services consulting, customer support and training. Because we only commenced
selling application servers in 1997, we have a limited operating history in the
application server market. We expect that, in the near term, the majority of our
revenues will be derived from PowerTier for C++ transactional server and related
services. In the longer term, we expect that PowerTier for EJB will increase as
a component of our total revenues.



     We market our software and services primarily through our direct sales
organizations in the United States, the United Kingdom and Germany. Revenues
from PowerTier licenses and services to customers outside the United States
represented approximately $566,000, or 15% of total revenues, in 1996, $639,000,
or 12% of total revenues, in 1997, $2.9 million, or 29% of total revenues, in
1998, and $626,000, or 22% of total revenues, in the three months ended March
31, 1999. Our future success will depend, in part, on our successful development
of international markets for our products.


                                       21
<PAGE>   27


     Historically, we have received a substantial portion of our revenues from
product sales to a limited number of customers. Sales of products to our top
five customers accounted for 15% of total revenues in 1997 and 55% of total
revenues in 1998. In the future, we expect to have relatively few large
customers continue to account for a relatively large proportion of our revenues.


     To date, we have sold our products primarily through our direct sales
force, and we will need to hire many more sales people within the next two years
in order to meet our sales goals. In addition, our ability to achieve
significant revenue growth will depend in large part on our success in
establishing and leveraging relationships with systems integrators and other
third parties.


     For 1997 and prior years, we recognized revenues in accordance with the
American Institute of Certified Public Accountants Statement of Position 91-1.
Commencing in 1998, we began recognizing revenues in accordance with the
American Institute of Certified Public Accountants Statement of Position 97-2,
"Software Revenue Recognition," or SOP 97-2, as amended by Statements of
Position 98-4 and 98-9. Our adoption of these new standards has not to date had
any material effect on our revenue recognition. Further implementation
guidelines relating to these standards may result in unanticipated changes in
our revenue recognition practices, and these changes could affect our future
revenues and earnings.



     We recognize license revenues upon shipment of the software if collection
of the resulting receivable is probable, an executed agreement has been signed,
the fee is fixed or determinable and vendor-specific objective evidence exists
to allocate a portion of the total fee to any undelivered elements of the
arrangement. Undelivered elements in these arrangements typically consist of
services. For sales made through distributors, revenue is recognized upon
shipment. Distributors have no right of return. We recognize revenues from
customer training, support and consulting services as the services are
performed. We generally recognize support revenues ratably over the term of the
support contract. If support or professional services are included in an
arrangement that includes a license agreement, amounts related to support or
professional services are allocated based on vendor-specific objective evidence.
Vendor-specific objective evidence for support and professional services is
based on the price when such elements are sold separately, or, when not sold
separately, the price established by management having the relevant authority.
Arrangements which require significant modification or customization of software
are recognized under the percentage of completion method.


     Since inception, we have incurred substantial research and development
costs and have invested heavily in the expansion of our sales, marketing and
professional services organizations to build an infrastructure to support our
long-term growth strategy. The number of our full-time employees increased from
64 as of December 31, 1997 to 77 as of December 31, 1998, representing an
increase of 20%. As a result of investments in our infrastructure, we have
incurred net losses in each fiscal quarter since 1996 and, as of March 31, 1999,
had an accumulated deficit of $14.7 million. We anticipate that our operating
expenses will increase substantially for the foreseeable future as we expand our
product development, sales and marketing and other staff. In addition, we expect
to incur substantial expenses associated with sales personnel, referral fees,
marketing programs and increased administrative expenses associated with being a
public company. Accordingly, we expect to incur net losses for the foreseeable
future.

     We believe that period-to-period comparisons of our operating results are
not meaningful and should not be relied upon as indicative of future
performance. Our

                                       22
<PAGE>   28

prospects must be considered in light of the risks, expenses and difficulties
frequently encountered by companies in early stages of development, particularly
companies in new and rapidly evolving markets. Although we have experienced
significant revenue growth recently, this trend may not continue. We may not
achieve or maintain profitability in the future. Our success depends
significantly upon broad market acceptance of our PowerTier for EJB application
server. Because Sun Microsystems controls the EJB standard, we need to maintain
a good working relationship with them to develop future versions of PowerTier
for EJB, as well as additional products using the EJB standard. Our performance
will also depend on the growth and widespread adoption of the market for
business-to-business electronic commerce over the Internet.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1998 AND 1999

  Revenues


     Our revenues were $1.7 million for the three months ended March 31, 1998
and $2.9 million for the three months ended March 31, 1999, representing an
increase of 67%. International revenues were $390,000 for the three months ended
March 31, 1998 and $626,000 for the three months ended March 31, 1999.



     License Revenues.  License revenues were $1.0 million for the three months
ended March 31, 1998 and $2.1 million for the three months ended March 31, 1999,
representing an increase of 111%. License revenues represented 59% of total
revenues for the three months ended March 31, 1998 and 74% of total revenues for
the three months ended March 31, 1999. The increase in software license revenues
was primarily due to sales of our new PowerTier for EJB application server and
the increased size and productivity of our sales team.



     Service Revenues.  Our service revenues were $706,000 for the three months
ended March 31, 1998 and $747,000 for the three months ended March 31, 1999,
representing an increase of 6%. The dollar increase in service revenues was
primarily due to an increase in customer support fees related to increased sales
of our PowerTier platform. Service revenues represented 41% of total revenues
for the three months ended March 31, 1998 and 26% of total revenues for the
three months ended March 31, 1999. This decrease as a proportion of total
revenues was primarily attributed to an increase in sales of our new PowerTier
for EJB platform.


  Cost of Revenues


     Cost of License Revenues.  Cost of license revenues consists of packaging,
documentation and associated shipping costs. Our cost of license revenues was
$56,000 for the three months ended March 31, 1998 and $42,000 for the three
months ended March 31, 1999. As a percentage of license revenues, cost of
license revenues were 6% for the three months ended March 31, 1998 and 2% for
the three months ended March 31, 1999. This decrease was primarily attributable
to lower packaging and document distribution costs as a result of a change to
electronic distribution of these materials.



     Cost of Service Revenues.  Cost of service revenues consists of personnel
and other costs related to professional services, technical support and
training. Our cost of service revenues was $326,000 for the three months ended
March 31, 1998 and $580,000 for the three months ended March 31, 1999,
representing an increase of 78%. This increase was primarily due to increased
staffing in our professional services organization to support a greater
installed base of customers. As a percentage of service revenues, cost of
service


                                       23
<PAGE>   29


revenues were 46% for the three months ended March 31, 1998 and 78% for the
three months ended March 31, 1999. In particular, cost of service revenues as a
percentage of service revenues may vary between periods due to our use of third
party professional services.


  Operating Expenses


     Sales and Marketing.  Sales and marketing expenses consist primarily of
salaries, commissions and bonuses earned by sales and marketing personnel,
travel and entertainment, and promotional expenses. Our sales and marketing
expenses were $1.7 million for the three months ended March 31, 1998 and $2.0
million for the three months ended March 31, 1999, representing an increase of
19%. This increase was primarily due to our investment in our sales and
marketing infrastructure, which included significant personnel-related costs to
recruit and hire sales people and sales engineers, sales commissions and trade
show expenses. Sales and marketing expenses represented 99% of total revenues
for the three months ended March 31, 1998 and 70% of total revenues for the
three months ended March 31, 1999. We believe that a significant increase in our
sales and marketing efforts is essential for us to maintain our market position
and further increase acceptance of our products. Accordingly, we anticipate we
will continue to invest significantly in sales and marketing for the foreseeable
future, and sales and marketing expenses will increase in future periods.



     Research and Development.  Research and development expenses consist
primarily of salaries and benefits for software developers, product managers and
quality assurance personnel and payments to outside software developers. Our
research and development expenses were $1.0 million for the three months ended
March 31, 1998 and $1.8 million for the three months ended March 31, 1999,
representing an increase of 74%. This increase was primarily related to an
increase in employee and consultant software developers and program management
and documentation personnel hired to support product development. We also
recognized a one-time $303,000 compensation charge associated with the issuance
of common stock to an investor at a price which was less than the deemed fair
value for accounting purposes. Research and development expenses represented 61%
of total revenues for the three months ended March 31, 1998 and 63% of total
revenues for the three months ended March 31, 1999. We believe that a
significant increase in our research and development investment is essential for
us to maintain our market position, to continue to expand our product line and
to enhance our technology. Accordingly, we anticipate that we will continue to
invest significantly in product research and development for the foreseeable
future, and research and development expenses are likely to increase in future
periods.



     General and Administrative.  General and administrative expenses consist
primarily of salaries, benefits and related costs for our finance,
administrative and general management personnel. Our general and administrative
expenses were $311,000 for the three months ended March 31, 1998 and $383,000
for the three months ended March 31, 1999, representing an increase of 23%. This
increase was primarily the result of the hiring of additional finance and
administrative personnel. General and administrative expenses represented 18% of
total revenues for the three months ended March 31, 1998 and 13% of total
revenues for the three months ended March 31, 1999. We believe that our general
and administrative expenses will continue to increase as a result of the
expenses associated with being a public company, including annual and other
public reporting costs, directors' and officers' liability insurance, investor
relations programs and accounting and legal expenses.


                                       24

     Net Interest Income.  Net interest income was $4,000 for the three months
ended March 31, 1998 and $48,000 for the three months ended March 31, 1999,
representing an increase of $44,000. Net interest income consists primarily of
earnings on our cash and cash equivalent balances.



     Stock-Based Compensation.  Some options granted and common stock issued
during the years ended December 31, 1997 and 1998 and during the three months
ended March 31, 1999 have been considered to be compensatory, as the estimated
fair value for accounting purposes was greater than the stock price as
determined by the board of directors on the date of grant or issuance. Total
deferred stock compensation associated with equity transactions as of March 31,
1999 amounted to $2.7 million, net of amortization. Deferred stock compensation
is being amortized ratably over the vesting periods of these securities.
Amortization expense was $25,000 in the three months ended March 31, 1998 and
$504,000 in the three months ended March 31, 1999.


YEARS ENDED DECEMBER 31, 1996, 1997 AND 1998

  Revenues


     Our revenues were $3.8 million in 1996, $5.4 million in 1997 and $10.2
million in 1998, representing increases of 88% from 1997 to 1998 and 43% from
1996 to 1997. Revenues derived from international operations were $566,000 in
1996, $639,000 in 1997 and $2.9 million in 1998. In 1998, sales of software
licenses to Cisco accounted for 14% of total revenues, and sales of software
licenses to Instinet accounted for 17% of total revenues. In 1997, sales of
products to Lucent accounted for 11% of total revenues.



     License Revenues.  Our license revenues were $2.6 million in 1996, $3.5
million in 1997 and $7.5 million in 1998, representing increases of 111% from
1997 to 1998 and 36% from 1996 to 1997. License revenues represented 69% of
total revenues in 1996, 66% of total revenues in 1997 and 74% of total revenues
in 1998. The increase in license revenues from 1997 to 1998 was attributable
primarily to an increase in the size and productivity of our sales force,
including the introduction of our direct sales team in Europe, and the release
of our PowerTier for EJB product. The increase in revenues from 1996 to 1997 was
primarily due to the introduction of our PowerTier product family.



     Service Revenues.  Our service revenues were $1.2 million in 1996, $1.9
million in 1997 and $2.7 million in 1998, representing increases of 44% from
1997 to 1998 and 59% from 1996 to 1997. Service revenues represented 31% of
total revenues in 1996, 34% of total revenues in 1997 and 26% of total revenues
in 1998. The increase in service revenues between 1997 and 1998 was primarily
due to an increase in customer support fees related to an increase in our
installed base of PowerTier customers, and, to a lesser extent, an increase in
professional services fees. The increase in service revenues between 1996 and
1997 was primarily due to an increase in both professional services and customer
support fees.


  Cost of Revenues


     Cost of License Revenues.  Cost of license revenues was $139,000 in 1996,
$342,000 in 1997 and $239,000 in 1998, representing a decrease of 30% from 1997
to 1998 and an increase of 146% from 1996 to 1997. Cost of license revenues as a
percentage of license revenues was 5% in 1996, 10% in 1997 and 3% for 1998. The
decrease in cost of license revenues from 1997 to 1998 was attributable
primarily due to lower packaging and document distribution costs. The increase
in cost of license revenues from 1996 to 1997 was attributable primarily to a
higher level of printed documentation.


                                       25
<PAGE>   31


     Cost of Service Revenues.  Cost of service revenues was $221,000 in 1996,
$729,000 in 1997 and $1.4 million in 1998, representing increases of 88% from
1997 to 1998 and 230% from 1996 to 1997. Cost of service revenues as a
percentage of service revenues was 19% in 1996, 39% in 1997 and 51% for 1998.
The increases during these periods were due to increased staffing in our
professional services and support organizations.


  Operating Expenses


     Sales and Marketing.  Sales and marketing expenses were $3.8 million in
1996, $4.7 million in 1997 and $7.2 million in 1998, representing increases of
52% from 1997 to 1998 and 24% from 1996 to 1997. Sales and marketing expenses
represented 101% of total revenues in 1996, 87% of total revenues in 1997 and
71% of total revenues for 1998. The dollar increases during these periods
primarily reflected our investment in our sales and marketing infrastructure,
which included significant personnel-related expenses such as salaries, benefits
and commissions, and, to a lesser extent, travel and entertainment expenses,
trade shows and other marketing expenses.



     Research and Development.  Research and development expenses were $2.0
million in 1996, $3.0 million in 1997 and $4.2 million in 1998, representing
increases of 43% from 1997 to 1998 and 50% from 1996 to 1997. Research and
development expenses represented 52% of total revenues in 1996, 55% of total
revenues in 1997 and 42% of total revenues in 1998. The dollar increases during
these periods were primarily related to the increase in headcount to support
product development and, to a lesser extent, an increase in average
compensation.



     General and Administrative.  General and administrative expenses were $1.0
million in 1996, $1.4 million in 1997 and $1.2 million in 1998, representing a
decrease of 9% from 1997 to 1998 and an increase of 38% from 1996 to 1997.
General and administrative expenses represented 26% of total revenues in 1996,
25% of total revenues in 1997 and 12% of total revenues in 1998. The dollar
decrease in general and administrative expenses from 1997 to 1998 was
attributable primarily to a decrease in consulting fees, offset in part by an
increase in headcount and average compensation. The dollar increase in general
and administrative expenses from 1996 to 1997 was attributable primarily to an
increase in headcount, and legal and accounting expenses.



     Net Interest Income.  Net interest income was $34,000 in 1996, $12,000 in
1997 and $1,000 in 1998. Net interest income consists primarily of earnings on
our cash and cash equivalent balances, offset by interest expense related to
obligations under capital leases and other borrowings. The decrease in net
interest income from 1997 to 1998 was due to an increase in interest expense
related to obligations under capital leases and an equipment loan. The decrease
in interest income from 1996 to 1997 was due to a lower level of average cash
and cash equivalent balances.



     Stock-Based Compensation.  We recorded no stock-based compensation expense
for 1996 and 1997. As of December 31, 1998, total deferred stock compensation
associated with equity transactions amounted to $2.2 million, net of
amortization. Amortization expense was $331,000 in 1998. We expect to record
amortization expense related to these securities of approximately $1.1 million
in 1999, $800,000 in 2000 and $800,000 in 2001.


     Provision for Income Taxes.  Since inception, we have incurred net
operating losses for federal and state tax purposes and have not recognized any
tax provision or benefit. As of December 31, 1998, we had $10.8 million of
federal and $3.6 million of state net operating loss carryforwards available to
offset future taxable income. The federal net

                                       26
<PAGE>   32

operating loss carryforwards expire through 2018, while the state net operating
loss carryforwards expire through 2003. The net operating loss carryforwards for
state tax purposes are substantially less than for federal tax purposes,
primarily because only 50% of state net operating loss carryforwards can be
utilized to offset future state taxable income. The Tax Reform Act of 1986
limits the use of net operating loss carryforwards in situations where changes
occur in the stock ownership of a company. If we should be acquired or otherwise
have an ownership change, as defined in the Tax Reform Act of 1986, our
utilization of these carryforwards could be restricted.


     As of December 31, 1998, the Company also had research and development tax
credit carryforwards of $570,000 and $320,000 available to offset future federal
and state income taxes. The federal credit carryforward expires in 2018, while
the state credit carryforward has no expiration.



     We have placed a full valuation allowance against our net deferred tax
assets due to the uncertainty surrounding the realization of these assets. We
evaluate on a quarterly basis the recoverability of the net deferred tax assets
and the level of the valuation allowance. If and when we determine that it is
more likely than not that the deferred tax assets are realizable, the valuation
allowance will be reduced.

QUARTERLY RESULTS OF OPERATIONS


     The following table sets forth unaudited consolidated statement of
operations data for the nine quarters in the 27-month period ended March 31,
1999, as well as this data expressed as a percentage of our total revenues for
the periods indicated. This data has been derived from our unaudited
consolidated financial statements, which have been prepared on the same basis as
the audited consolidated financial statements and, in the opinion of our
management, include all adjustments, consisting of normal recurring adjustments,
necessary for a fair presentation of the information when read in conjunction
with the consolidated financial statements and notes thereto. Our quarterly
results have been in the past and may in the future be subject to significant
fluctuations. As a result, we believe that results of operations for interim
periods should not be relied upon as any indication of the results to be
expected in any future period.

     Our quarterly operating results have fluctuated significantly in the past,
and may continue to fluctuate in the future, as a result of a number of factors,
many of which are outside our control. These factors include:

     - our ability to close relatively large sales on schedule;

     - delays or deferrals of customer orders or deployments;

     - delays in shipment of scheduled software releases;

     - demand for and market acceptance of our PowerTier for C++ and PowerTier
       for EJB products;

     - the possible loss of sales people;

     - introduction of new products or services by us or our competitors;

     - annual or quarterly budget cycles of our customers;

     - the level of product and price competition in the application server
       market;

     - our lengthy sales cycle;

     - our success in expanding our direct sales force and indirect distribution
       channels;

     - the mix of direct sales versus indirect distribution channel sales;

     - the mix of products and services licensed or sold;

     - the mix of domestic and international sales; and


     - our success in penetrating international markets and general economic
       conditions in these markets.


     The typical sales cycle of our products is long and unpredictable, and is
affected by seasonal fluctuations as a result of our customers' fiscal year
budgeting cycles and slow summer purchasing patterns in Europe. We typically
receive a substantial portion of our orders in the last two weeks of each
quarter because our customers often delay purchases of our products to the end
of the quarter to gain price concessions. Because a substantial portion of our
costs are relatively fixed and based on anticipated revenues, a failure to book
an expected order in a given quarter would not be offset by a corresponding
reduction in costs and could adversely affect our operating results.


     Our license revenues in the first quarter of 1998 were lower than those in
the fourth quarter of 1997 and our license revenues in the first quarter of 1999
were lower than those in the fourth quarter of 1998. In the future, we expect
this trend to continue, with the fourth quarter of each year accounting for the
greatest percentage of total revenues for the year and with an absolute decline
in revenues from the fourth quarter to the first quarter of the next year.


LIQUIDITY AND CAPITAL RESOURCES

     Since inception, we have financed our business primarily through private
sales of convertible preferred stock, which totaled $19.9 million in aggregate
net proceeds through March 31, 1999. We have also financed our business through
a loan in the principal amount of $800,000 and capitalized leases. As of March
31, 1999, we had $7.4 million of cash and cash equivalents and $6.3 million of
working capital.


     Net cash used for operating activities was $3.1 million in 1996, $3.1
million in 1997, $3.0 million in 1998, and $1.7 million for the three months
ended March 31, 1999. For


                                       29
<PAGE>   35

each of 1996, 1997 and 1998, and for the three months ended March 31, 1999, cash
used for operating activities was attributable primarily to net losses and
increases in accounts receivable, offset by depreciation and amortization of
deferred stock compensation and deferred revenues.


     Net cash used for investing activities was $9,000 for 1996, $589,000 for
1997, $436,000 for 1998, and $96,000 for the three months ended March 31, 1999.
For each of the periods, cash used in investing activities primarily reflected
investments in property and equipment and deposits.



     Net cash provided by financing activities was $7.3 million for 1996, $1.8
million for 1997, $5.7 million for 1998, and $4.3 million for the three months
ended March 31, 1999. Cash provided by financing activities during these periods
was primarily attributable to proceeds from the issuance of preferred stock and,
in 1998, borrowings under a term loan, primarily offset by repayments of a
capital lease obligations.


     In February 1998, we entered into a loan agreement with Comerica Bank for
an amount up to $2,000,000. As of March 31, 1999 we had no borrowings
outstanding under this loan. As of March 31, 1999, we had an $800,000 promissory
note in favor of Comerica. We are required to make principal payments of $22,222
per month plus interest of 7.75% per annum on the unpaid principal balance,
payable in 36 monthly installments beginning April 1, 1999. The promissory note
is collateralized by substantially all of our assets, including our patents and
intellectual property.

     Although we have no material commitments for capital expenditures, we
anticipate a substantial increase in capital expenditures and lease commitments
consistent with our anticipated growth in operations, infrastructure and
personnel. We also may increase our capital expenditures as we expand into
additional international markets.


     We believe that the net proceeds from this offering, together with our
current cash, cash equivalents and short-term investments, will be sufficient to
meet our anticipated cash needs for working capital and capital expenditures for
at least the next 18 months. If cash generated from operations is insufficient
to satisfy our liquidity requirements, we may seek to sell additional equity or
debt securities or to obtain a credit facility. If additional funds are raised
through the issuance of debt securities, these securities could have rights,
preferences and privileges senior to holders of common stock, and the term of
this debt could impose restrictions on our operations. The sale of additional
equity or convertible debt securities could result in additional dilution to our
stockholders, and we may not be able to obtain additional financing on
acceptable terms, if at all. If we are unable to obtain this additional
financing, we may be required to reduce the scope of our planned product
development and marketing efforts, which could harm our business.


YEAR 2000 COMPLIANCE


     Many currently installed computer systems are unable to distinguish between
twentieth century dates and twenty-first century dates. These systems were
developed using two digits rather than four to determine the applicable year.
This error could result in software 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 product
versions, validation testing and contingency planning.

                                       30
<PAGE>   36

     We have largely completed all phases of this plan, except for contingency
planning, for the current versions of our products. As a result, we believe all
current versions of our products to be "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 with our products are also year
2000 compliant. We have not tested our products on all platforms or all versions
of operating systems that we currently support.

     We have defined "year 2000 compliant" as the ability to:

     - correctly handle date information needed for the December 31, 1999 to
       January 1, 2000 date change;

     - 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;

     - 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

     - recognize the year 2000 as a leap year.

     We have tested software obtained from third parties, including 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. We plan to continue to test our current and future products by
applying our year 2000 compliance criteria and to include any necessary
modifications the compliance process reveals. Despite testing and assurances,
our products may contain undetected errors or defects associated with year 2000
date functions. Any errors or defects in our products could result in the delay
or loss of revenue, increased service costs and damage to our reputation. We are
aware of lawsuits against software vendors involving year 2000 claims, and,
despite testing our products, we may be sued by a customer on a year 2000 claim.

     Our internal systems include both our information technology, or IT, and
non-IT systems. We have reviewed our material internal IT systems, including
both our custom software and third-party software and hardware technology, but
we have not performed an assessment of our non-IT systems. To the extent that we
cannot 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. If our current or future customers fail to
achieve year 2000 compliance or if they delay or divert technology expenditures,
especially technology expenditures that were reserved for enterprise software
systems, to address year 2000 compliance problems, our business could suffer.

     Through March 31, 1999, we have incurred nominal expenses relating to our
year 2000 compliance activities and estimate that any additional costs will be
nominal. However, we may experience material problems and costs that are not
currently identified in our year 2000 plan.

     We have not yet fully developed a contingency plan to address situations
that may result if we cannot achieve year 2000 readiness of our critical
operations. The cost of

                                       31
<PAGE>   37


developing and implementing a contingency plan may itself be material. We intend
to develop a contingency plan by the fourth quarter of 1999. Finally, we are
also subject to external forces that might generally affect businesses, such as
utility or transportation company year 2000 failures.


QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK


     Interest Rate Sensitivity.  Our operating results are sensitive to changes
in the general level of U.S. interest rates, particularly because most of our
cash equivalents are invested in short-term debt instruments. If market interest
rates were to change immediately and uniformly by ten percent from levels at
March 31, 1999, the fair value of our cash equivalents would change by an
insignificant amount.



     Foreign Currency Fluctuations.  We have not had any significant
transactions in foreign currencies, nor do we have any significant balances that
are due or payable in foreign currencies at March 31, 1999. Therefore, a
hypothetical ten percent change in foreign currency rates would have an
insignificant impact on our financial position or results of operations. We do
not hedge any of our foreign currency exposure.


RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1997, the Financial Accounting Standards Board issued accounting
statement No. 130, Reporting Comprehensive Income, which requires an enterprise
to report, by major components and as a single total, the change in its net
assets during the period from nonowner sources. We had no comprehensive income
items to report, other than net loss, for any of the periods presented. The FASB
also issued accounting statement No. 131, Disclosures About Segments of an
Enterprise and Related Information, which establishes annual and interim
reporting standards for an enterprise's business segments and related
disclosures about its products, services, geographic areas and major customers.
We currently operate in one reportable segment.

     In March 1998, the American Institute of Certified Public Accountants
issued SOP 98-1, Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use. This standard requires companies to capitalize
qualifying computer software costs, which are incurred during the application
development stage, and amortize them over the software's estimated useful life.
SOP 98-1 is effective for fiscal years beginning after December 15, 1998. We are
currently evaluating the impact of SOP 98-1 on our financial statements and
related disclosures.

     In June 1998, the Financial Accounting Standards Board issued accounting
statement No. 133, Accounting for Derivative Instruments and Hedging Activities.
This statement requires companies to record derivatives on the balance sheet as
assets or liabilities measured at fair value. Gains or losses resulting from
changes in the values of those derivatives would be accounted for depending on
the use of the derivative and whether it qualifies for hedge accounting. SFAS
No. 133 will be effective for us beginning in 2000. We are currently evaluating
the impact of SFAS No. 133 on our financial statements and related disclosures.

COMPANY OVERVIEW


     We are a leading provider of transactional application server software
products, which move data and processing out of back-end computer systems and
closer to users. Our software supports the Internet infrastructure that enables
the next generation of high-speed, high-volume electronic commerce applications.
Our PowerTier products are designed to address the scalability, availability and
adaptability demands of delivering business solutions over the Internet. Our
PowerTier platform is one of the few application server solutions that
implements the full Enterprise Java Beans, or EJB, standard to enable businesses
to deploy high performance, scalable Java applications. We believe that our
robust product architecture, which incorporates several patented technologies,
is particularly well suited to meet the infrastructure requirements of
business-to-business electronic commerce. Our major customers include AT&T,
Boeing, Cisco, FedEx, IBM, Instinet, Lucent, Morgan Stanley Dean Witter,
Norwest, Perkin-Elmer and SuperValu.


INDUSTRY BACKGROUND

     The Internet has evolved into a global communications medium enabling
millions of people to share information and conduct business electronically. As
the Internet's popularity has increased, companies in industries ranging from
securities trading to book selling are extending their core business processes
over the Web to conduct electronic commerce with customers, suppliers and
partners. The growth of these electronic commerce offerings has led to
significant growth in the number of users and transactions conducted over the
Web.


     While creating new business opportunities, the significant growth of
electronic commerce has also created tremendous technological challenges for
electronic commerce companies struggling to meet the needs of rapidly increasing
numbers of users. These companies are discovering that their existing Internet
software infrastructure is unable to support thousands of concurrent users or
process up to thousands of transactions per second. Even casual observers of the
Internet are familiar with these limitations, which include:


     - Poor performance:  Initial electronic commerce offerings were not
       designed to scale to handle large numbers of users. Internet users
       accessing these systems often experience lengthy delays as the number of
       concurrent users increases.

     - System failures:  Initial electronic commerce offerings did not
       anticipate the level of robustness required to operate 24 hours a day, 7
       days a week. Internet users accessing these systems at peak volume can
       experience frequent system crashes.

     - Limited adaptability:  Initial electronic commerce offerings were built
       on software infrastructures that offered only limited ability for
       customization and personalization. To remain competitive, companies must
       continuously enhance and differentiate their electronic commerce
       offerings.


     While these problems have been well-publicized in the business-to-consumer
market, we believe that business-to-business interactions face even more
pronounced problems due to the added complexity of managing transactions between
multiple companies. In addition, the growth of the business-to-business
electronic commerce market is expected to outpace the growth of the
business-to-consumer market. While Forrester Research estimates that the
business-to-consumer market in the United States is expected to grow


                                       33
<PAGE>   39

from $7.8 billion in 1998 to $108 billion in 2003, they estimate that the
business-to-business electronic commerce market in the United States will grow
even more rapidly, from $43 billion to $1.3 trillion, in this same period.

     In large part, the problems facing these organizations, both in
business-to-business and business-to-consumer electronic commerce, are derived
from the continuing evolution and increasing sophistication of web-based
applications. In the early days of the Internet, organizations turned to the Web
for information publishing, decision support and simple transaction processing.
This first generation of web-based applications focused on extending legacy
applications to the Internet. These applications were typically not
business-critical, and had relatively simple interactions and limited
functionality. The web application server emerged as the infrastructure used to
support these first generation applications.

     Today, use of the Web has changed dramatically as the Web has emerged as a
leading platform for conducting electronic commerce. The number of individuals
and organizations conducting transactions over the Internet has increased
significantly, as organizations have offered increasingly sophisticated and
feature-rich electronic commerce applications. At the same time, as
organizations have begun to conduct significant volumes of business over the
Internet, system failures and delays in transaction processing have ceased to be
mere inconveniences and have become serious impediments to doing business. To
achieve a competitive advantage in today's environment, many businesses are
looking to create web-based electronic commerce offerings that are available 24
hours per day, 7 days per week and that enhance customer loyalty by leveraging
partner, supplier and third party relationships. Complicating these challenges
further is the need to rapidly develop and deploy these applications on
"Internet time."

     As the Internet has evolved into a critical business platform, the
limitations of the software infrastructure used to support electronic commerce
have become apparent. The first generation web application servers were not
designed to accommodate the high transaction volumes and high performance
requirements that characterize electronic commerce today.

     The next generation of electronic commerce will require a fundamentally new
software infrastructure, based on an application server platform optimized for
high volume transaction processing over the Internet. The platform must provide:

     - Real-time scalability:  accommodate up to thousands of end users with
       consistent sub-second response times;


     - High availability:  handle system failures without interruption and
       without losing critical information for potentially thousands of
       concurrent users;


     - Rapid adaptability:  allow companies to continuously improve their
       business processing through automated development and management of
       differentiated electronic commerce offerings; and

     - Business-to-business integration:  enable businesses to extend their
       processing across organizational boundaries.

PERSISTENCE SOLUTION

     Our PowerTier family of products consists of transactional application
servers that are specifically designed to enable high volume, high performance
electronic commerce applications. Our products, PowerTier for EJB and PowerTier
for C++, address the

                                       34
<PAGE>   40

scalability, availability and adaptability demands that typically occur when
delivering business solutions over the Internet. Our products offer the
following key benefits:

     Real-Time Response for Thousands of Concurrent Users.  Our PowerTier
platform was designed specifically to accommodate high volume transaction
processing and the data integrity requirements of distributed applications. The
platform utilizes our patented caching technology. Caching is a process in which
relational data is pulled out of back-end systems and into the PowerTier server
cache, which allows the data to be shared and manipulated at the application
server level. Replication between PowerTier server caches using the PowerSync
feature allows a cluster of PowerTier servers to provide highly scalable
performance as the number of users increases. This architecture helps reduce the
work load on back-end systems and accelerates application performance. The
effect of this architecture is to minimize unnecessary network traffic and
thereby enable high performance and reliability even with significant
transaction volumes. We believe our PowerTier platform offers performance that
is orders of magnitude faster than traditional non-caching application servers.

     Dramatic Reductions In Time-to-Market for Electronic Commerce
Applications.  Our PowerTier platform decreases time to market and development
cycles for sophisticated electronic commerce applications due to our proprietary
and patented object-to-relational mapping technology. This technology enables
the automatic generation of software code, which minimizes basic, low-level
programming tasks, such as security and database access. The PowerTier platform
accelerates development by giving developers access to data in a familiar way,
as software components, and provides application developers with a framework to
rapidly build electronic commerce applications.

     Protects and Leverages Existing Information Technology Investments.  The
PowerTier platform enables developers to build new electronic commerce
applications while simultaneously integrating existing back-end systems.
PowerTier's flexible architecture integrates with disparate database servers,
web servers and multiple clients, while supporting multiple programming
languages and computing platforms. PowerTier provides enhanced flexibility and
interoperability to link existing enterprise applications and systems, allowing
businesses to leverage their investments in information technology and extend
them over the Internet.

     Leadership in Emerging Standards.  Customers are increasingly seeking open,
standards-based technology solutions that enable them to develop and implement
new applications rapidly. Our PowerTier products provide one of the few
application server solutions that implements the full EJB specification to
enable businesses to deploy high performance, scalable Java applications for the
enterprise. We worked with the Sun Microsystems consortium to define an
industry-wide component standard to be used when building enterprise
applications with the Java language. It is this standard upon which our
PowerTier platform is built, and we believe that this emerging platform has the
potential to dramatically simplify the development of distributed, multi-tier
electronic commerce applications. As EJB and other emerging electronic commerce
standards evolve, we intend to continue to be a leading adopter and contributor
to these technologies.

     Optimized Platform For Business-to-Business Electronic Commerce.  Our
transactional application server is designed and optimized to enable complex
online transactions, providing the necessary scalable, reliable and secure
infrastructure. Platforms designed to support the next generation of
business-to-business electronic commerce applications must handle hundreds and
potentially thousands of concurrent users while simultaneously providing
reliability and security, and enabling connections to a myriad of existing and

                                       35
<PAGE>   41

emerging back-end applications. In addition, we believe our PowerTier products
are particularly well suited for multi-party, multi-step business-to-business
transactions that require server-to-server communication.

PERSISTENCE STRATEGY

     Our objective is to become the leading provider of transactional
application server software products that comprise the Internet software
infrastructure for high volume, high performance electronic commerce
applications. To achieve this goal, we intend to:

     Capture Market Share in the Emerging Business-to-Business Electronic
Commerce Market.  We intend to become the market leader in providing software
infrastructure to enable sophisticated business-to-business electronic commerce
applications. To achieve this objective, we will continue to make significant
investments in building our sales and marketing organizations. We plan to launch
a variety of sales and marketing programs designed to capture market share. For
example, we plan to use a seeding strategy to extend our market share by
offering a development version of our software that may be downloaded over the
Internet to provide wide dissemination of our product to developers. We also
offer educational seminars on our products and the advantages of EJB. We will
continue to collaborate with our innovative and advanced customers to develop
and deliver product features that address their needs. We believe that this
collaboration focuses our overall product development effort and speeds our
time-to-market.

     Extend Technology Leadership Position in Standards-Based Platforms for Next
Generation Electronic Commerce.  We intend to extend our technology leadership
in the transactional application server market by enhancing our underlying
technology to offer real-time scalability, high availability and rapid
adaptability for the next generation of electronic commerce applications. To
achieve this objective, we will continue to make significant investments in our
research and development organization. In addition, we intend to be a leader in
the definition and adoption of emerging technology standards, such as EJB, which
we believe have the potential to dramatically simplify the development of
distributed, multi-tier applications. We have been a pioneer in the areas of
caching and object-relational mapping, and hold several patents on core
technologies. We intend to continue to innovate and create new enabling
technologies for electronic commerce.


     Expand Product Platform to Offer Complementary Solutions.  In addition to
extending our technology leadership, we intend to broaden and enhance our
product platform to incorporate complementary solutions for developing and
deploying sophisticated electronic commerce applications. We will continue to
make investments in our research and development organization for many of these
product initiatives. We will also consider, from time to time, bolstering these
internal efforts with strategic acquisitions. For example, we have recently
acquired object request broker technology, which provides the communications
link between the transactional application server and the client. The addition
of these complementary technologies will enable us to offer a broader platform
for our customers.


     Increase Partnerships With Systems Integrators.  We intend to continue to
develop and expand relationships with systems integrators. We believe these
third parties can effectively market our products through their existing
relationships with our target market customers. In addition, our PowerTier
platform is often included as part of an enterprise-wide system deployment, in
which the system integrator plays a leading role. We believe that these
relationships will provide additional marketing and sales channels for our

currently working with a number of systems integrators, including: Alta
Software, Andersen Consulting, Cambridge Technology Partners, Component Systems,
Computer Sciences Corporation, Electronic Data Systems, Genesis Development
Corporation and Unisys.

     Leverage Installed Customer Base.  We believe that there are significant
opportunities to expand the use of our products throughout our current customer
base. Although most organizations initially deploy our products on a
departmental or pilot basis, we believe that initial customer success with these
deployments will lead to significant opportunities for enterprise-wide adoption.
Further, we believe that most companies, including our customers, are just
beginning to fully capitalize on the opportunities created by the Web. As these
companies increasingly migrate their core business processes to the Web, we
believe they will need additional licenses of our software to support and enable
their new electronic commerce applications.

     Strengthen International Presence.  We believe there are significant
international opportunities for our products and services. We intend to continue
to build our sales, marketing and services organizations in Europe to capitalize
on these opportunities. Currently, we have established direct sales operations
in the United Kingdom and Germany, and we intend to open an office in France. In
addition to our direct sales operations, we also distribute our products
throughout Europe with distributors and systems integrators. We intend to
continue to build and extend these international third-party distributor and
systems integrator relationships.

PowerTier for EJB

     Our PowerTier for EJB application server platform incorporates our patented
technologies into one of the few transactional application servers to deliver
the full EJB version 1.0 standard. The EJB standard, as defined by the JavaSoft
division of Sun Microsystems, is gaining rapid acceptance as a programming
language for complex enterprise applications. EJB provides a consistent way to
program and integrate services for companies building distributed
business-to-business applications with the Java programming language.

                                       38
<PAGE>   44

     The EJB standard specifies container-managed persistent objects, which
automate the mapping between EJB components and relational database tables. This
feature allows programmers to build complex applications quickly by making
relational data look like software components, which can be easily manipulated.
We worked with the Sun Microsystems consortium to help define the initial EJB
standard, and we continue to contribute to new versions of the EJB standard. Our
PowerTier for EJB platform runs on the Windows NT and Unix operating systems.

     The latest version of our PowerTier for EJB adds a new architecture,
PowerSync, to enable enterprise scalability and interoperability. PowerSync is a
cache replication architecture, which allows companies to deploy tens to
hundreds of PowerTier servers, each with a mirror image of every other server's
data. This PowerSync feature enables companies to address increasing demands on
an application by easily adding additional servers, all operating with
synchronized, high-performance PowerTier caching. This version of PowerTier for
EJB is currently in use by several of our major customers and is scheduled for
commercial release in 1999.

PowerTier for C++


     Our PowerTier for C++ product is a high-performance transactional
application server platform, which is based on our patented technologies and the
Common Object Request Broker Architecture, or CORBA, standard for communication
between distributed applications. The CORBA standard is managed by an industry
group called the Object Management Group, of which we are a contributing member.
We are also one of the authors, along with Oracle, IBM and others, of an
emerging component of the overall CORBA standard, called the Persistent State
Service specification. Our PowerTier for C++ platform runs on the Windows NT and
Unix operating systems.

Patented Technology Platform

     Our application server cache software architecture and cache replication
technology have been designed to serve as the foundation for a variety of
scalable electronic commerce applications.

     - Shared Caching.  Our cache technology is the foundation for the high
       performance characteristics of our transactional application server. To
       maximize performance, dynamic information such as product inventory data
       is retrieved from a database into the application server cache. This
       in-memory information may be accessed simultaneously by multiple users,
       saving each user from having to access a disk-based database for that
       information. This feature reduces network traffic between the application
       server and the database, delivering higher performance.

     - Transactional Caching.  To enable users to get a consistent view of
       information within the shared cache, our technology prevents one user
       from seeing uncommitted changes made by another user. The ability of our
       shared application server cache to isolate users from dynamic changes to
       component information, such as inventory data, differentiates our
       application server cache from other caching technologies which can only
       manage static information, such as web pages. This feature allows high
       performance caching of dynamic or transactional information.

     - Cache Replication.  Our cache replication technology provides the
       foundation for the scalability, stateful availability and fault tolerance
       of our transactional application server. We define stateful availability
       as a system that can transfer a user in the middle of a complex business
       operation, such as a portfolio valuation, from one application server to
       another without interruption or losing business state, such as the user's
       portfolio information. To provide stateful scalability, information from
       one application server cache can be synchronized with information in one
       or more other application server caches. Companies can deploy additional
       replicated application server caches to increase their ability to support
       more users, allowing them to use several smaller computers to do the work
       of one larger and more expensive computer. Users' requests are
       automatically routed to the application server with the most free
       capacity, enabling high performance, notwithstanding increases in user
       volumes. In the event of an application server failure, that application
       server's responsibilities are automatically reassigned to another
       application server, improving system availability.

     - Cluster Management.  We have developed complementary, proprietary
       administration software, which enables remote administration for clusters
       of application servers, reducing both administrative costs and the
       possibility of error. This management software also enables centralized
       monitoring, via a standard web browser, of the cluster through any
       individual application server. This feature contributes to greater system
       availability and reduced administrative costs.


     - Development Automation.  Our PowerTier development environment includes
       frameworks to automate or eliminate many development tasks. The
       proprietary and patented object-relational mapping feature automatically
       generates the software code to translate software components into
       relational databases. This feature reduces the programming time required
       to build enterprise applications. The PowerTier application server
       includes pre-built software services for data management, transaction
       management and communications, relieving the developer from having to
       build these services from scratch.


                                       40
<PAGE>   46


     - Standards-based.  The PowerTier application server platform uses an open
       architecture that is based on industry standards such as Java, C++,
       CORBA, Windows NT, UNIX, SQL and others.



     We believe that research and product development will be a key to our
success as a leader in the transactional application server market. Our research
and development expenditures totaled $2.0 million for 1996, $3.0 million for
1997, $4.2 million for 1998, and $1.8 million for the three months ended March
31, 1999.

REAL-TIME ELECTRONIC TRADING NETWORK


     Instinet Corporation.  Instinet is the world's largest electronic agency
broker in equity securities. Today, trading in fixed income securities occurs
almost exclusively over the telephone. Instinet plans to revolutionize this
telephone-based fixed income trading with a global electronic broker trading
service for fixed income dealers that can accommodate up to 1,000 transactions
per second. It has designed a system which, while still being tested and not yet
generally available, is expected to use hundreds of replicated PowerTier
application servers operating in concert when fully deployed to meet the
performance and scalability requirements of its electronic fixed income broker
service.


INTRANET SUPPLY CHAIN MANAGEMENT


     Federal Express Corporation.  The world's largest express transportation
company, FedEx transports more than three million items to over 200 countries
each business day, using a fleet of more than 620 aircraft and 44,000 vehicles.
In its effort to improve on-time deliveries, FedEx has built a global operations
center to monitor and control the movement of shipments worldwide. The global
operations center functions as the nerve center of the FedEx transportation
system, handling daily occurrences including changing flight schedules,
emergency maintenance, inclement weather and excess package volumes. Because the
company's existing mainframe systems lacked the required flexibility and
performance, FedEx turned to us for help in building a high performance intranet
system. By managing complex flight schedule information from multiple data
sources within a PowerTier application server cache, the global operations
center can provide real-time contingency plans, enabling FedEx to provide
consistently high on-time package delivery rates and superior customer service.
FedEx estimates that, using the PowerTier development environment, it has been
able to significantly reduce development time for new system functionality
compared to development in its traditional mainframe environment.


INTERNET SERVICE PROVIDER NETWORK MANAGEMENT

     Cisco Systems, Inc.  A worldwide leader in networking for the Internet,
Cisco Systems is committed to delivering hardware and software solutions that
enable Service Providers to meet the rapid growth of the Internet. The Cisco
Service Management System, or CSM, gives Service Providers sophisticated tools
to automate time consuming network management tasks. For this system, Cisco
required a highly scalable, standards-based application server platform for
deploying network management applications for managed business services such as
virtual private networks, Internet telephony and electronic commerce. To meet
these requirements, Cisco chose the PowerTier platform. For the Cisco IP Manager
product within the CSM system, PowerTier application server caching enables
real-time simulation of network configuration changes, preventing costly network
outages. The PowerTier development environment also enables Cisco to create a
common component framework that can be reused to reduce development time for
future CSM network services.

APPLICATION OUTSOURCING OVER THE INTERNET

     PE Genscope.  PE GenScope, recently incorporated into Celera Genomics,
provides gene discovery and characterization services for drug discovery and
development. Celera's

                                       42
<PAGE>   48


GeneTag technology is a novel gene expression analysis method that enables
pharmaceutical companies to develop new and potentially life-saving drugs by
discovering and monitoring genes involved in disease. Celera's BioScope software
application allows customers to access their data securely and remotely over the
Internet. To allow clients to quickly analyze and view the GeneTag results,
Celera needed a sophisticated software platform that could process hundreds of
thousands of gene expression comparisons while avoiding data bottlenecks. Celera
selected PowerTier to achieve these goals. The BioScope application utilizes the
PowerTier application server cache for high volume data analysis. With the
PowerTier development environment, Celera has been able to use both the Java and
C++ languages to deliver the BioScope software application in only four months.


SALES AND MARKETING

     We sell our products through both a direct sales force and third party
distributors. As of March 31, 1999, we had 32 people in our sales and marketing
organization, of which 26 were in the United States and six were in our London
and Munich offices. To support the complex enterprise nature of our sales, our
direct sales force is organized into two-member teams of one sales
representative and one sales engineer. We intend to increase the size of our
direct sales force and to establish additional sales offices domestically and
internationally.

     Our sales cycle is relatively long, generally between three and nine
months. A successful sales cycle typically includes presentations to both
business and technical decision makers, as well as a limited pilot program to
establish technical fit.

     We engage in a variety of marketing activities, including advertising,
public relations, seminars, trade shows and web site management. In particular,
we have made substantial marketing investments in education and training for the
EJB and C++ markets. We trained over 2,000 developers in 1998 in the EJB
standard. Our web site allows developers to download a demonstration version of
our products.

     Systems integrators represent an important and growing referral channel for
our direct sales effort. Systems integrators frequently have relationships with
our target customers and often incorporate our PowerTier platform as part of a
much larger enterprise-wide system enhancement. Currently we have relationships
with global and regional systems integrators, including:

     - Alta Software

     - Andersen Consulting

     - Cambridge Technology Partners

     - Component Systems

     - Computer Sciences Corporation

     - Electronic Data Systems

     - Genesis Development Corporation

     - Unisys

     In international markets, we plan to expand our sales through indirect
channels, such as distributors and original equipment manufacturers. As of March
31, 1999, we were represented by five international distributors, who sell our
products in Europe, Asia and Latin America.

COMPETITION

     The market for our products is intensely competitive, subject to rapid
change and significantly affected by new product introductions and other market
activities of industry participants. We believe that the principal competitive
factors in our market are:

     - performance, including scalability, integrity and availability;

     - ability to provide a complete software platform;

     - flexibility;

     - use of standards-based technology;

     - ease of integration with customers' existing enterprise systems;

     - quality of support and service;

     - security;

     - company reputation; and

     - price.

     Our competitors include both publicly and privately-held enterprises,
including BEA Systems (WebLogic), Gemstone Systems, IBM (WebSphere), Inprise,
Iona Technologies, Oracle (OAS) and Sun Microsystems (NetDynamics). Many
customers may not be willing to purchase our PowerTier platform because they
have already invested heavily in databases and other enterprise software
components offered by these competing companies. Many of these competitors have
preexisting customer relationships, longer operating histories, greater
financial, technical, marketing and other resources, greater name recognition
and larger installed bases of customers than we do. Moreover, there are other
very large and established companies, including Microsoft and Netscape, who
offer alternative solutions and are thus indirect competitors. Further, dozens
of companies have announced their intention to support EJB, and may compete
against us in the future. These competitors and potential competitors may be
able to respond more quickly to new or emerging technologies and changes in
customer requirements, or to devote greater resources to the development,
promotion and sale of their products than we can. See also "Risk
Factors -- Because we compete with Sun Microsystems, who controls the EJB
application server standard, we face the risk that they may develop this
standard to favor their own products" and " -- Microsoft has established a
competing application server standard, which could diminish the market potential
for our products if it gains widespread acceptance."

     In addition, in the PowerTier for C++ market, many potential customers
build their own custom application servers, so we effectively compete against
our potential customers' internal information technology departments.

INTELLECTUAL PROPERTY RIGHTS

     Our performance may depend on our ability to protect our proprietary rights
to the technologies used in our principal products. If we are not adequately
protected, our competitors can use the intellectual property that we have
developed to enhance their products and services, which would harm our business.
We rely on a combination of patents, copyright and trademark laws, trade
secrets, confidentiality provisions and other contractual provisions to protect
our proprietary rights, but these legal means afford only limited protection. As
of April 1999, we had three issued United States patents and one

                                       44
<PAGE>   50

pending United States patent application with allowable subject matter. Despite
any measures taken to protect our intellectual property, unauthorized parties
may attempt to copy aspects of our products or to obtain and use information
that we regard as proprietary. In addition, the laws of some foreign countries
may not protect our proprietary rights as fully as do the laws of the United
States. Thus, the measures we are taking to protect our proprietary rights in
the United States and abroad may not be adequate. Finally, our competitors may
independently develop similar technologies.


     The software industry is characterized by the existence of a large number
of patents and frequent litigation based on allegations of patent infringement
and the violation of other intellectual property rights. As the number of
entrants into our market increases, the possibility of an intellectual property
claim against us grows. For example, we may be inadvertently infringing a patent
of which we are unaware. In addition, because patent applications can take many
years to issue, there may be a patent application now pending of which we are
unaware, which will cause us to be infringing when it issues in the future. To
address these patent infringement claims, we may have to enter into royalty or
licensing agreements on disadvantageous commercial terms. Alternatively, we may
be unable to obtain a necessary license. A successful claim of product
infringement against us, and our failure to license the infringed or similar
technology, would harm our business. In addition, any infringement claims, with
or without merit, would be time-consuming and expensive to litigate or settle
and would divert management attention from administering our core business.



     In March 1998, we entered into a license agreement with Sun Microsystems,
pursuant to which we granted Sun Microsystems rights to manufacture and sell, by
itself and not jointly with others, products under a number of our patents and
Sun Microsystems granted us rights to manufacture and sell, by ourselves and not
jointly with others, products under a number of Sun Microsystems' patents. As a
result, Sun Microsystems may develop and sell competing products that would, in
the absence of this license agreement, infringe our patents. Under this
agreement, Sun Microsystems made a one-time payment to us. Neither Sun
Microsystems nor we can transfer the license without the consent of the other
party.


EMPLOYEES


     As of March 31, 1999, we had 81 full-time employees, including 35 in
research and development, 32 in sales and marketing, six in professional
services and eight in general and administrative functions. From time to time,
we also employ independent contractors to support our engineering, marketing,
sales and support and administrative organizations.


FACILITIES


     We are headquartered in San Mateo, California, where we lease approximately
17,000 square feet of office space under a lease expiring on June 30, 1999. We
are currently negotiating an extension of this lease. We also maintain sales
offices in California, Georgia, Illinois, New York, Texas and the United Kingdom
and Germany. We believe that our existing facilities are adequate to meet our
current and foreseeable requirements or that suitable additional or substitute
space will be available as needed.


LEGAL PROCEEDINGS


     We are not currently subject to any material legal proceedings. We may from
time to time become a party to various legal proceedings arising in the ordinary
course of business.

BOARD COMPOSITION


     Our certificate of incorporation and bylaws currently provide for a board
of directors consisting of eight members. Beginning at the first annual meeting
of stockholders after the annual meeting of stockholders at which we have at
least 800 stockholders, the board of directors will be divided into three
classes, each serving staggered three-year terms: Class I, whose term will
expire at the first annual meeting of stockholders after our first annual
meeting of stockholders at which we have 800 stockholders; Class II, whose term
will expire at the second annual meeting of stockholders after our first annual
meeting of stockholders at which we have 800 stockholders; and Class III, whose
term will expire at the third annual meeting of stockholders after our first
annual meeting of stockholders at which we have 800 stockholders. As a result,
only one class of directors will be elected at each annual meeting of
stockholders of Persistence, with the other classes continuing for the remainder
of their respective terms. Gregory Ennis and William Harding were elected to the
board of directors pursuant to a voting agreement between us and our principal
stockholders. This voting agreement will terminate upon completion of this
offering. Our officers are appointed by the board of directors and serve at the
discretion of the board of directors.


BOARD COMPENSATION

     Our directors do not currently receive compensation for their services as
members of the board of directors. Employee directors are eligible to
participate in our 1997 stock plan and will be eligible to participate in our
1999 employee stock purchase plan. Nonemployee directors are eligible to
participate in our 1997 stock plan and will be eligible to participate in our
1999 directors' stock option plan. See "Stock Plans."


     In April 1998, the board of directors granted Mr. Lutz an option to
purchase 35,000 shares of common stock at $0.50 per share. The option becomes
exercisable at the rate of 1/4th of the total number of shares on January 1,
1999 and 1/48th of the total shares per month thereafter. In July 1998, the
Board granted Mr. Lutz a fully-vested option to purchase 3,572 shares of common
stock at $0.50 per share in consideration of consulting services rendered by Mr.
Lutz to us. In July 1998, the board of directors granted Mr. Hancock an option
to purchase 35,000 shares of common stock at $0.50 per share in connection with
his appointment as a director. The option becomes exercisable at the rate of
1/4th of the total number of shares on July 30, 1999 and 1/48th of the total
shares per month thereafter. All these options were granted under the 1997 stock
plan and have not been exercised.



     We engage R.B. Webber & Company, of which Mr. Webber is President, to
perform market and business analyses for us on a project by project basis.
Pursuant to this arrangement, we paid R.B. Webber & Company $18,700 in 1997 and

CHANGE OF CONTROL AGREEMENTS


     We have entered into change of control agreements with Alan Cohen, Mark
Douglas, Erik Frieberg, Barry Goss, Christine Russell and Laurence Hootnick,
which provide that


                                       51
<PAGE>   57

100% of the stock options or restricted stock held by the officer shall
immediately vest if he or she is terminated without cause or resigns for good
reason within 12 months after a change of control transaction.

OPTION GRANTS


     We did not grant any stock options to our Chief Executive Officer or four
other most highly compensated executive officers during the year ended December
31, 1998. In February 1999, we granted Christine Russell and Alan Cohen each an
option to purchase 20,000 shares of common stock at $1.65 per share. Each option
becomes exercisable at the rate of 1/4th of the total number of shares on
February 18, 2000 and 1/48th of the total per month thereafter. Both options
were granted under the 1997 Stock Plan and have not been exercised.


AGGREGATE OPTION EXERCISES AND HOLDINGS


     No options were held or exercised during the year ended December 31, 1998
by our Chief Executive Officer or our four other most highly compensated
executive officers. In February 1999, we granted Christine Russell and Alan
Cohen the options described above, none of which have been exercised.


STOCK PLANS


     1997 Stock Plan.  Our 1997 stock plan provides for the grant of incentive
stock options to employees, including employee directors, and of nonstatutory
stock options and stock purchase rights to employees, directors (including
employee directors) and consultants. The purposes of the 1997 stock plan are to
attract and retain the best available personnel, to provide additional
incentives to our employees and consultants and to promote the success of our
business. The 1997 stock plan was originally adopted by our board of directors
in April 1997 and approved by our stockholders in July 1997. The 1997 stock plan
has been amended a number of times, most recently in April 1999, when the board
of directors reserved an additional 3,000,000 shares of common stock for
issuance under the 1997 stock plan and made other changes. This latest amendment
will be submitted for approval by our stockholders prior to completion of this
offering. As of the date of this offering, a total of 5,609,652 shares of common
stock has been reserved for issuance under the 1997 stock plan (not including
38,645 shares that may be returned to our 1994 stock purchase plan, described
below, upon our repurchase of such shares from participants when they terminate
employment), plus an automatic annual increase on the first day of each of our
fiscal years beginning in 2001, 2002, 2003, 2004 and 2005 equal to the lesser of
650,000 shares, 3.5% of our outstanding common stock on the last day of the
immediately preceding fiscal year, or a lesser number of shares as determined by
the board of directors. Unless terminated earlier by the board of directors, the
1997 stock plan will terminate in April 2007.



     As of March 31, 1999, options to purchase 1,388,036 shares of common stock
were outstanding under the 1997 stock plan at a weighted average exercise price
of $0.64 per share, 826,583 shares had been issued upon exercise of outstanding
options or pursuant to restricted stock purchase agreements, and 395,033 shares
remained available for future grant.



     The 1997 stock plan may be administered by the board of directors or a
committee of the board, each known as the administrator. The administrator
determines the terms of options and stock purchase rights granted under the 1997
stock plan, including the number of shares subject to the award, the exercise or
purchase price, and the vesting or exercisability of the award and any other
conditions to which the award is subject. In no


                                       52
<PAGE>   58


event, however, may an employee receive awards for more than 2,000,000 shares
under the 1997 stock plan in any fiscal year. Incentive stock options granted
under the 1997 stock plan must have an exercise price of at least 100% of the
fair market value of the common stock on the date of grant. Prior to this
offering, nonstatutory stock options and stock purchase rights granted under the
1997 stock plan were required to have an exercise or purchase price of at least
85% of the fair market value of the common stock on the date of grant, and
grants to employees who were not officers must vest at least 20% per year. After
the date of this offering, the exercise price of nonstatutory stock options and
the purchase price of stock purchase rights will no longer be subject to these
restrictions, although nonstatutory stock options and stock purchase rights
granted to our Chief Executive Officer and our four other most highly
compensated officers will generally equal at least 100% of the grant date fair
market value. Payment of the exercise or purchase price may be made in cash or
such other consideration as determined by the administrator.



     With respect to options granted under the 1997 stock plan, the
administrator determines the term of options, which may not exceed 10 years (or
5 years in the case of an incentive stock option granted to a holder of more
than 10% of the total voting power of all classes of our stock). Generally, an
option granted under the 1997 stock plan is nontransferable other than by will
or the laws of descent and distribution, and may be exercised during the
lifetime of the optionee only by that optionee. However, the administrator may
in its discretion provide for the limited transferability of nonstatutory stock
options granted under the 1997 stock plan under circumstances specified in the
1997 stock plan. Stock issued pursuant to stock purchase rights granted under
the 1997 stock plan is generally subject to a repurchase right exercisable by
Persistence Software upon the termination of the holder's employment or
consulting relationship with us for any reason (including death or disability).
This repurchase right will lapse in accordance with the terms of the stock
purchase right determined by the administrator at the time of grant.



     If we are acquired by another corporation, each outstanding option and
stock purchase right may be assumed or an equivalent award substituted by our
acquirer. However, if the acquirer does not agree to this assumption or
substitution, then unvested shares and options terminate. The administrator has
the authority to amend or terminate the 1997 plan, but no action may be taken
that impairs the rights of any holder of an outstanding option or stock purchase
right without the holder's consent. In addition, we must obtain stockholder
approval of amendments to the plan as required by applicable law.



     1994 Stock Purchase Plan.  The 1994 stock purchase plan was originally
adopted by our board of directors in July 1994 and approved by our stockholders
in July 1994. It provides for the grant of stock purchase rights to employees
and a total of 640,598 shares of common stock have been reserved for issuance
under the 1994 stock purchase plan. As of March 31, 1999, 640,598 shares of
common stock had been issued pursuant to restricted stock purchase agreements
under the 1994 stock purchase plan. No shares remained available for future
grant, and we do not intend to issue any further awards under this plan. Unless
sooner terminated by the board of directors, the 1994 stock purchase plan will
terminate in July 2004.



     Stock purchase rights granted under the 1994 stock purchase plan were
required to have a purchase price of at least 85% of the fair market value of
the shares as of the date of the offer. Recipients of stock purchase rights
under the 1994 stock purchase plan execute a restricted stock purchase agreement
granting us an option to repurchase the shares subject to the award at the
recipient's original purchase price upon termination of the recipient's
employment with us prior to vesting. The shares generally vest, and our
repurchase right


                                       53
<PAGE>   59


lapses, over a four year period at the rate of one fourth of the total shares on
the annual anniversary of the vesting commencement date and 1/48th of the total
shares on the monthly anniversary of the vesting commencement date thereafter.
Payment of the purchase price is permitted to be made in cash or other
consideration as determined by the plan's administrator. Shares returned to the
1994 plan are automatically transferred to the 1997 plan.



     1999 Employee Stock Purchase Plan.  Our 1999 employee stock purchase plan
was adopted by the board of directors in April 1999 and will be submitted for
approval by our stockholders prior to completion of this offering. A total of
600,000 shares of common stock has been reserved for issuance under the 1999
employee stock purchase plan, none of which have been issued as of the date of
this offering. The number of shares reserved for issuance under the 1999
employee stock purchase plan will be subject to an automatic annual increase on
the first day of each of our fiscal years beginning in 2000, 2001, 2002, 2003
and 2004 equal to the lesser of 250,000 shares, 1% of our outstanding common
stock on the last day of the immediately preceding fiscal year, or a lesser
number of shares as determined by the board of directors. The 1999 employee
stock purchase plan becomes effective upon the date of this offering. Unless
terminated earlier by the board of directors, the 1999 employee stock purchase
plan will terminate twenty years following the date of this offering.



     The 1999 employee stock purchase plan, which is intended to qualify under
Section 423 of the Internal Revenue Code, will be implemented by a series of
overlapping offering periods of approximately 24 months' duration, with new
offering periods (other than the first offering period) commencing on February 1
and August 1 of each year. Each offering period will generally consist of four
consecutive purchase periods of six months' duration, at the end of which an
automatic purchase will be made for participants. The initial offering period is
expected to commence on the date of this offering and end on July 31, 2001; the
initial purchase period is expected to begin on the date of this offering and
end on January 31, 2000, with subsequent purchase periods ending on July 31,
2000, January 31, 2001 and July 31, 2001. The 1999 employee stock purchase plan
will be administered by the board of directors or by a committee appointed by
the board. Our employees (including officers and employee directors), or
employees of any majority-owned subsidiary designated by the board, are eligible
to participate in the 1999 employee stock purchase plan if they are employed at
least 20 hours per week and more than five months per year. The 1999 employee
stock purchase plan permits eligible employees to purchase common stock through
payroll deductions, which in any event may not exceed 20% of an employee's base
salary. The price at which stock is purchased under the 1999 employee stock
purchase plan is equal to the lower of 85% of the fair market value of the
common stock at the beginning of each offering period or at the end of each
purchase period. Employees may end their participation in the 1999 employee
stock purchase plan at any time during an offering period, and participation
ends automatically on termination of employment. The board may implement
provisions of the 1999 employee stock purchase plan that permit stock purchases
through cash or stock contributions.



     An employee cannot be granted an option under the 1999 employee stock
purchase plan if immediately after the grant that employee would own stock or
hold outstanding options to purchase stock equaling 5% or more of the total
voting power or value of all classes of our stock or stock of our subsidiaries,
or if the option would give an employee rights to purchase stock under the 1999
employee stock purchase plan at a rate that exceeds $25,000 of fair market value
of the stock for each calendar year in which the option is outstanding. In
addition, no employee may purchase more than 2,500 shares of


                                       54
<PAGE>   60


common stock under the 1999 employee stock purchase plan in any one purchase
period. If the fair market value of the common stock on a purchase date is less
than the fair market value at the beginning of the offering period, each
participant in that offering period shall automatically be withdrawn from the
offering period as of the end of the purchase date and re-enrolled in the new
twenty-four month offering period beginning on the first business day following
the purchase date.



     If we merge or consolidate with or into another corporation or sell all or
substantially all of our assets, each right to purchase stock under the 1999
employee stock purchase plan will be assumed or an equivalent right substituted
by the successor corporation unless our acquiror does not agree to assume or
substitute outstanding rights, in which case the offering period then in
progress will be shortened so that employees' rights to purchase stock under the
1999 employee stock purchase plan are exercised prior to the transaction. The
board of directors has the power to amend or terminate the 1999 employee stock
purchase plan and to change or terminate offering periods as long as this action
does not adversely affect any outstanding rights to purchase stock thereunder.
However, the board of directors may amend or terminate the 1999 purchase plan or
an offering period even if it would adversely affect outstanding options in
order to avoid our incurring adverse accounting charges. In addition, the
purchase price may be adjusted during an offering period in order to avoid our
incurring adverse accounting charges.



     1999 Directors' Stock Option Plan.  The 1999 directors' stock option was
adopted by the board of directors in April 1999 and will be submitted for
approval by our stockholders prior to completion of this offering. It will
become effective upon the date of this offering. A total of 500,000 shares of
common stock has been reserved for issuance under the 1999 directors' plan, all
of which remain available for future grants. The 1999 directors' plan provides
for the grant of nonstatutory stock options to our nonemployee directors. The
1999 directors' plan is designed to work automatically without administration.
To the extent administration is necessary, it will be performed by the board of
directors. To the extent conflicts of interest arise, it is expected that they
will be addressed by abstention of any interested director from both
deliberations and voting regarding matters in which that director has a personal
interest. Unless terminated earlier, the 1999 directors' plan will terminate ten
years from the date of this offering in April 2009.



     The 1999 directors' plan provides that each person who becomes a
nonemployee director after the completion of this offering will be granted: (1)
a nonstatutory stock option to purchase 20,000 shares of common stock on the
date on which he or she first becomes a member of our board of directors, (2) an
additional nonstatutory stock option to purchase 20,000 shares on the one year
anniversary of his or her election as a director and (3) an additional
nonstatutory stock option to purchase 4,000 shares on the first day of each
fiscal year beginning at least two years after his or her election as a
director. Each nonemployee director who was a member of the board of directors
before the completion of the offering will be granted an option to purchase
4,000 shares of common stock on the first day of each fiscal year beginning on
January 1, 2000.



     All options granted under the 1999 directors' plan will have a term of ten
years and an exercise price equal to the fair market value of our common stock
on the date of grant and will be nontransferable. All options granted under the
1999 directors' plan shall vest in full immediately upon grant. If a nonemployee
director ceases to serve as a director for any reason other than death or
disability, he or she may, but only within 90 days after the date he or she
ceases to be a director, exercise options granted under the directors' plan. If
he or she does not exercise the option within this 90-day period, the option
shall terminate. If


                                       55
<PAGE>   61

a director's service terminates as a result of his or her disability or death,
or if a director dies within three months following termination for any reason,
the director or his or her estate will have 12 months after the date of
termination or death, as applicable, to exercise options that were vested as of
the date of termination.


     If we are acquired by another corporation, each option outstanding under
the directors' plan will be assumed or equivalent options substituted by our
acquirer, unless our acquirer does not agree to this assumption or substitution,
in which case the options will terminate upon consummation of the transaction to
the extent not previously exercised. Our board of directors may amend or
terminate the 1999 directors' plan as long as that action does not adversely
affect any outstanding option and we obtain stockholder approval for any
amendment to the extent required by applicable law.


LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

     Our certificate of incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach
of their fiduciary duties as directors, except liability for:

     - any breach of their duty of loyalty to the corporation or its
       stockholders;

     - acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

     - unlawful payments of dividends or unlawful stock repurchases or
       redemptions; or

     - any transaction from which the director derived an improper personal
       benefit.


     This limitation of liability does not apply to liabilities arising under
the federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission. Our certificate of
incorporation and bylaws provide that we shall indemnify our directors and
executive officers and may indemnify our other officers and employees and other
agents to the fullest extent permitted by law. We believe that indemnification
under our bylaws covers at least negligence and gross negligence on the part of
indemnified parties. Our bylaws also permit us to secure insurance on behalf of
any officer, director, employee or other agent for any liability arising out of
or her actions in that capacity, regardless of whether the bylaws would permit
indemnification.



     We have entered into agreements to indemnify our directors and executive
officers in addition to indemnification provided for in our bylaws. These
agreements, among other things, provide for indemnification of our directors and
executive officers for expenses specified in the agreements, including
attorneys' fees, judgments, fines and settlement amounts incurred by a director
or executive officer in any action or proceeding arising out of his or her
services as a director or executive officer of Persistence, any subsidiary of
Persistence or any other entity to which he or she provides services at our
request. In addition, we maintain directors' and officers' insurance. We believe
that these provisions and agreements are necessary to attract and retain
qualified persons as directors and executive officers.


     At present, we are not aware of any pending or threatened litigation or
proceeding involving a director, officer, employee or agent in which
indemnification would be required or permitted. We are not aware of any
threatened litigation or proceeding that might result in a claim for such
indemnification.

                              CERTAIN TRANSACTIONS

     In April 1997, we issued Derek Henninger, one of our executive officers,
1,700 shares of common stock at $0.23 per share under the 1994 stock purchase
plan. In December 1997, we issued each of Barry Goss, Alan Cohen and Christine
Russell, each of whom is an executive officer, 260,000 shares of common stock at
$0.23 per share under the 1997 stock plan. All these shares are subject to a
right of repurchase at cost in our favor which lapses at the rate of 1/4th of
the total number of shares on the first anniversary of the vesting commencement
date and 1/48th of the total number of shares per month thereafter.


     In April 1998, we granted Mark Douglas, Janet McGraw and Erik Frieberg,
each an executive officer, options to purchase 130,000, 75,000 and 75,000 shares
of common stock, respectively, at $0.50 per share. In July 1998, we granted Jack
L. Hancock, one of our directors, an option to purchase 35,000 shares of common
stock at $0.50 per share in connection with his appointment as a director. In
July 1998, we granted Mark Douglas an option to purchase 65,000 shares of common
stock at $0.50 per share and we granted Janet McGraw an option to purchase
35,000 shares of common stock at $0.50 per share. In October 1998, we granted
Erik Frieberg an option to purchase 55,000 shares of common stock at $0.60 per
share. In February 1999, we granted Christine Russell and Alan Cohen each an
option to purchase 20,000 shares of common stock at $1.65 per share. In April
1999, we granted Janet McGraw and Mark Douglas each an option to purchase 20,000
shares of common stock at $10.00 per share. All these options become exercisable
at the rate of 1/4th of the total number of shares on the first anniversary of
the vesting commencement date and 1/48th of the total number of shares per month
thereafter. All these options were granted under the 1997 stock plan and have
not been exercised.



     In April 1999, we granted Gregory Ennis, Jack Hancock, Larry Henninger,
William Harding, Merritt Lutz and Jeffrey Webber, who serve as our directors,
each an option under the 1997 stock plan to purchase 10,000 shares of common
stock at $10.00 per share. In April 1999, we also granted Joseph Roebuck, who
serves as our director, an option under the 1997 stock plan to purchase 20,000
shares of common stock at $10.00 per share. These options are fully-vested and
have not been exercised.



     In April 1999, we granted Laurence Hootnick, our President and a director,
an option to purchase 850,000 shares of common stock at $10.00 per share. The
option is immediately exercisable. However, if the option is exercised, the
underlying shares are subject to a right of repurchase at $10.00 per share in
our favor in the event Mr. Hootnick ceases employment with us. Our repurchase
option lapses at the rate of 1/4th of the total number of shares on the first
anniversary of the vesting commencement date and 1/48th of the total number of
shares per month thereafter. In April 1999, we also granted Mr. Hootnick an
option to purchase 340,000 shares of common stock at $10.00 per share. The
option vests upon the earlier of five years or the attainment of specified
revenue milestones within 36 months of Mr. Hootnick's first date of employment.



     In April 1998, we granted Merritt Lutz, one of our directors, an option to
purchase 35,000 shares of common stock at $0.50 per share. The option becomes
exercisable at the rate of 1/48th of the total number of shares on January 1,
1999 and 1/48th of the total shares per month thereafter. In connection with
consulting services tendered to us, we granted Mr. Lutz a fully-vested option to
purchase 3,572 shares of common stock at $0.50 per share in July 1998, a
fully-vested option to purchase 6,288 shares of common stock at $1.65 per share
in February 1999, and a fully-vested option to purchase 393 shares of common
stock at $10.00 per share in April 1999. All of these options were granted under
the 1997 stock plan and have not been exercised.

     We engage R.B. Webber & Company to perform market and business analysis for
us on a project by project basis. Jeffrey Webber, one of our directors, is
President of R.B. Webber. In connection with these services, we paid R.B. Webber
& Company $18,700 in 1997 and $20,500 in 1998. In addition, we have issued Mr.
Webber common stock in connection with consulting services rendered to us by Mr.
Webber. In April 1996, we issued Mr. Webber 29,060 shares of common stock at
$0.23 per share. In November 1996, we issued Mr. Webber 3,300 shares of common
stock at $0.23 per share. All these shares were issued under the 1994 stock
purchase plan.



     Larry E. Henninger, who served on our board of directors from February 1994
to April 1999, is the father of Derek P. Henninger, our Vice President of
Engineering. We have an unwritten consulting arrangement with Larry Henninger,
pursuant to which we paid Mr. Henninger $18,000 per year during each of 1996,
1997 and 1998. In April 1997, in connection with these consulting services, we
sold Mr. Henninger 7,000 shares of common stock at $0.23 per share. We currently
intend to continue to pay Mr. Henninger $1,500 per month as a retainer for
consulting services.



     We entered into change of control agreements with Christine Russell on
February 18, 1997, with Alan Cohen on December 31, 1997, with Barry Goss on
January 1, 1998, with Erik Frieberg on March 23, 1998, with Mark Douglas on
April 1, 1998 and with Laurence Hootnick on April 29, 1999. These change of
control agreements provide that restricted stock or stock options granted to
these officers under the 1997 stock plan will immediately vest if they are
terminated without cause or resign for good reason within 12 months after our
change of control. This offering will not constitute a change of control.


     The following executive officers have issued full recourse promissory notes
in our favor in order to purchase shares of common stock pursuant to stock
purchase rights granted under the 1997 stock plan:

     We have entered into indemnification agreements with our officers and
directors containing provisions that may require us to indemnify our officers
and directors against liabilities that may arise by reason of their status or
service as officers or directors, other than liabilities arising from willful
misconduct of a culpable nature, and to advance their expenses incurred as a
result of any proceeding against them.


     In November 1996, we entered into a technology development and license
agreement with Morgan Stanley Dean Witter & Co., pursuant to which Morgan
Stanley Dean Witter paid us a purchase advance of $50,000 and granted us a
source code license to incorporate specific technology into products to be
developed for Morgan Stanley Dean Witter and other commercial use. If we default
under the agreement, Morgan Stanley Dean Witter is entitled to use portions of
our source code specified in the agreement to develop products for internal use
and to use object code versions of specified products we have developed under
the agreement. We recognized revenue of $300,000 from Morgan Stanley Dean Witter
in 1997 and revenue of $168,000 from Morgan Stanley Dean Witter in 1998. At
December 31, 1998, we had $30,000 of deferred revenue and $101,000 of accounts

                          DESCRIPTION OF CAPITAL STOCK

     Upon the completion of this offering, we will be authorized to issue
75,000,000 shares of common stock, $0.001 par value, and 5,000,000 shares of
undesignated preferred stock, $0.001 par value. The following description of our
capital stock is intended to be a summary and does not describe all provisions
of our certificate of incorporation or bylaws or Delaware law applicable to
Persistence. For a more thorough understanding of the terms of our capital
stock, you should refer to our certificate of incorporation and bylaws, which
are included as exhibits to the registration statement of which this prospectus
is a part.

COMMON STOCK


     As of March 31, 1999, there were 15,447,941 shares of common stock
outstanding, held of record by approximately 108 stockholders, which reflects
the conversion of all outstanding shares of preferred stock into common stock.
In addition, as of March 31, 1999, there were 1,388,036 shares of common stock
subject to outstanding options and 80,556 shares of common stock subject to
outstanding warrants. Upon completion of this offering, there will be 18,447,941
shares of common stock outstanding, assuming no exercise of the underwriters'
overallotment option or additional exercise of outstanding options under our
stock option plan and warrants.



     The holders of common stock are entitled to one vote per share on all
matters to be voted upon by stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock, holders of common stock are
entitled to receive ratably dividends as may be declared by the board of
directors out of funds legally available for that purpose. In the event of our
liquidation, dissolution or winding up, the holders of common stock are entitled
to share ratably in all assets remaining after payment of liabilities and the
liquidation preference of any outstanding preferred stock. The common stock has
no preemptive or conversion rights, other subscription rights, or redemption or
sinking fund provisions. All outstanding shares of common stock are fully paid
and non-assessable, and the shares of common stock to be issued upon completion
of this offering will be fully paid and non-assessable.


PREFERRED STOCK


     Upon the closing of the offering, all outstanding shares of preferred stock
will be converted into 7,697,885 shares of common stock and automatically
retired. Thereafter, the board of directors will have the authority, without
further action by the stockholders, to issue up to 5,000,000 shares of preferred
stock in one or more series and to designate the rights, preferences, privileges
and restrictions of each series. The issuance of preferred stock could have the
effect of restricting dividends on the common stock, diluting the voting power
of the common stock, impairing the liquidation rights of the common stock or
delaying or preventing our change in control without further action by the
stockholders. We have no present plans to issue any shares of preferred stock.


WARRANTS

     As of March 31, 1999 there were warrants outstanding to purchase a total of
55,556 shares of common stock at a price of $0.90 per share, which expire on
December 31, 2001. In addition, there were warrants outstanding to purchase a
total of 25,000 shares of common stock at $0.90 per share, which expire on
February 6, 2001.

REGISTRATION RIGHTS

     The holders of 7,726,434 shares of common stock and warrants to purchase
80,556 shares of common stock (the "registrable securities") are entitled to
have their shares registered by us under the Securities Act under the terms of
an agreement between us and the holders of the registrable securities. Subject
to limitations specified in the agreement, these registration rights include the
following:


     - The holders registrable securities may require, on two occasions
       beginning six months after the date of this prospectus, that we use our
       best efforts to register the registrable securities for public resale,
       provided that the aggregate offering price for these registrable
       securities is at least $5,000,000. This right is subject to the ability
       of the underwriters to limit the number of shares included in the
       offering in view of market conditions.



     - If we register any common stock, either for our own account or for the
       account of other security holders, the holders of registrable securities
       are entitled to include their shares of common stock in that
       registration. This right is subject to the ability of the underwriters to
       limit the number of shares included in the offering in view of market
       conditions.



     - The holders of at least 1% of the then outstanding registrable securities
       may require us to register all or a portion of their registrable
       securities on Form S-3 when use of this form becomes available to us,
       provided that the proposed aggregate offering price is at least
       $1,000,000. The holders of registrable securities may not exercise this
       right within six months immediately following the effective date of a
       Form S-3 registration previously demanded by the holders of registrable
       securities or more than once in any twelve-month period.



     We will bear all registration expenses other than underwriting discounts
and commissions, except in the case of registrations on Form S-3 demanded after
one such registration on Form S-3 has already been declared effective. All
registration rights terminate on the date five years following the closing of
this offering, or, with respect to each holder of registrable securities, at the
time when the holder owns less than 2% of the voting stock and is entitled to
sell all of its shares in any three month period under Rule 144 of the
Securities Act.


DELAWARE ANTI-TAKEOVER LAW AND PROVISIONS OF OUR CERTIFICATE OF INCORPORATION
AND BYLAWS


     Provisions of Delaware law and our certificate of incorporation and bylaws
could make it more difficult for a third party to acquire us or to remove our
incumbent officers and directors. These provisions, summarized below, are
expected to discourage coercive takeover practices and inadequate takeover bids
and to encourage persons seeking to acquire control of Persistence to first
negotiate with us. We believe that the benefits of increased protection of our
ability to negotiate with the proponent of an unfriendly or unsolicited
acquisition proposal outweigh the disadvantages of discouraging these proposals
because, among other things, negotiation could result in an improvement of their
terms.


     We are subject to Section 203 of the Delaware General Corporation Law,
which regulates corporate acquisitions. In general, Section 203 prohibits a
publicly held Delaware corporation from engaging in a business combination with
an interested stockholder for a

                                       63
<PAGE>   69

period of three years following the date the person became an interested
stockholder, unless:


     - the board of directors approved the transaction in which the person
       became an interested stockholder prior to the date the interested
       stockholder attained this status;



     - upon consummation of the transaction that resulted in the person's
       becoming an interested stockholder, he or she owned at least 85% of the
       voting stock of the corporation outstanding at the time the transaction
       commenced, excluding shares owned by persons who are directors and also
       officers; or



     - on or subsequent to the date the business combination is approved by the
       board of directors and authorized at an annual or special meeting of
       stockholders.


     A business combination generally includes a merger, asset or stock sale, or
other transaction resulting in a financial benefit to the interested
stockholder. In general, an interested stockholder is a person who, together
with affiliates and associates, owns, or within three years prior to the
determination of interested stockholder status, did own, 15% or more of a
corporation's voting stock.

     Our certificate of incorporation and bylaws do not provide for the right of
stockholders to act by written consent without a meeting or for cumulative
voting in the election of directors. In addition, our certificate of
incorporation permits the board of directors to issue preferred stock with
voting or other rights without any stockholder action. Our certificate of
incorporation provides for the board of directors to be divided into three
classes, with staggered three-year terms, commencing at our first annual meeting
of stockholders following the date on which we have at least 800 stockholders.
As a result, only one class of directors will be elected at each annual meeting
of stockholders. Each of the two other classes of directors will continue to
serve for the remainder of its respective three-year term. These provisions,
which require the vote of stockholders holding at least two thirds of the
outstanding common stock to amend, may have the effect of deterring hostile
takeovers or delaying changes in our management.

TRANSFER AGENT AND REGISTRAR


     The transfer agent and registrar for the common stock is U.S. Stock
Transfer Corporation. The transfer agent's address and telephone number is 1745
Gardena Avenue, Glendale, CA, 91204, (818)502-1404.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Prior to this offering, there has been no market for our common stock.
Future sales of substantial amounts of common stock in the public market could
adversely affect prevailing market prices. As described below, no shares
currently outstanding will be available for sale immediately after this offering
because of contractual restrictions on resale. Sales of substantial amounts of
our common stock in the public market after the restrictions lapse could
adversely affect the prevailing market price and impair our ability to raise
equity capital in the future.


     Upon completion of the offering, we will have 18,447,941 outstanding shares
of common stock. Of these shares, the 3,000,000 shares sold in the offering,
plus any shares issued upon exercise of the underwriters' overallotment option,
will be freely tradable without restriction under the Securities Act, unless
purchased by our "affiliates" as that term is defined in Rule 144 under the
Securities Act. In general, affiliates include officers, directors or 10%
stockholders.



     The remaining 15,447,941 shares outstanding are restricted securities
within the meaning of Rule 144. Restricted securities may be sold in the public
market only if registered or if they qualify for an exemption from registration
under Rules 144, 144(k) or 701 promulgated under the Securities Act, which are
summarized below. Sales of restricted securities in the public market, or the
availability of these shares for sale, could adversely affect the market price
of the common stock.



     Our directors, officers and securityholders have entered into lock-up
agreements in connection with this offering generally providing that they will
not offer, sell, contract to sell or grant any option to purchase or otherwise
dispose of our common stock or any securities exercisable for or convertible
into our common stock owned by them for a period of 90 or 180 days after the
date of this prospectus without the prior written consent of BancBoston
Robertson Stephens. Notwithstanding possible earlier eligibility for sale under
the provisions of Rules 144, 144(k)and 701, shares subject to lock-up agreements
will not be salable until these agreements expire or are waived by BancBoston
Robertson Stephens. Taking into account the lock-up agreements, and assuming
BancBoston Robertson Stephens does not release stockholders from these
agreements, the following shares will be eligible for sale in the public market
at the following times:



     - Beginning on the effective date of this prospectus, only the 3,000,000
       shares sold in the offering will be immediately available for sale in the
       public market.



     - Beginning 90 days after the effective date, approximately 147,790 shares
       will be eligible for sale, none of which will be subject to volume,
       manner of sale and other limitations under Rule 144. None of these shares
       are held by affiliates.



     - Beginning 180 days after the effective date, approximately 14,434,150
       shares will be eligible for sale, 7,014,673 of which will be subject to
       volume, manner of sale and other limitations under Rule 144. All but
       3,636,301 of the total 14,434,150 shares are held by affiliates.


     - The remaining 866,001 shares will be eligible for sale pursuant to Rule
       144 upon the expiration of various one-year holding periods during the
       six months following 180 days after the effective date. All but 837,964
       of these shares are held by affiliates.

     In general, under Rule 144 as currently in effect, after the expiration of
the lock-up agreements, a person who has beneficially owned restricted
securities for at least one year

                                       65
<PAGE>   71

would be entitled to sell within any three-month period a number of shares that
does not exceed the greater of:


     - one percent of the number of shares of common stock then outstanding
       which will equal approximately 184,479 shares immediately after the
       offering; or


     - the average weekly trading volume of the common stock during the four
       calendar weeks preceding the sale.


     Sales under Rule 144 are also subject to requirements with respect to
manner of sale, notice, and the availability of current public information about
us. Under Rule 144(k), a person who is not deemed to have been our affiliate at
anytime during the three months preceding a sale, and who has beneficially owned
the shares proposed to be sold for at least two years, is entitled to sell his
or her shares without complying with the manner of sale, public information,
volume limitation or notice provisions of Rule 144.



     Rule 701, as currently in effect, permits our employees, officers,
directors or consultants who purchased shares pursuant to a written compensatory
plan or contract to resell these shares in reliance upon Rule 144 but without
compliance with specific restrictions. Rule 701 provides that affiliates may
sell their Rule 701 shares under Rule 144 without complying with the holding
period requirement and that non-affiliates may sell their shares in reliance on
Rule 144 without complying with the holding period, public information, volume
limitation or notice provisions of Rule 144.


     In addition, we intend to file registration statements under the Securities
Act as promptly as possible after the effective date to register shares to be
issued pursuant to our employee benefit plans. As a result, any options or
rights exercised under the 1994 stock purchase plan, the 1997 stock plan, the
1999 employee stock purchase plan, the 1999 directors' stock option plan or any
other benefit plan after the effectiveness of the registration statements will
also be freely tradable in the public market. However, such shares held by
affiliates will still be subject to the volume limitation, manner of sale,
notice and public information requirements of Rule 144 unless otherwise
resalable under Rule 701. As of March 31, 1999 there were outstanding options
for the purchase of 1,388,036 shares of common stock, of which options to
purchase 271,235 shares were exercisable.

     Shares sold by the underwriters will initially be offered to the public at
the initial public offering price set forth on the cover page of this
prospectus. Any shares sold by the underwriters to securities dealers may be
sold at a discount of up to      per share from the initial public offering
price. These securities dealers may resell any shares purchased from the
underwriters to other brokers or dealers at a discount of up to      per share
from the initial public offering price. If all the shares are not sold at the
initial public offering price, the representatives may change the offering price
and the other selling terms.



     Over-Allotment Option.  We have granted to the underwriters an option,
exercisable during the 30-day period after the date of this prospectus, to
purchase up to 450,000 additional shares of common stock at the same price per
share as we will receive for the 3,000,000 shares that the underwriters have
agreed to purchase. To the extent that the underwriters exercise this option,
each of the underwriters will have a firm commitment, to purchase approximately
the same percentage of such additional shares that the number of shares of
common stock to be purchased by it shown in the above table represents as a
percentage of the 3,000,000 shares in this offering. If purchased, these
additional shares will be sold by the underwriters on the same terms as those on
which the 3,000,000 shares are being sold.



     Indemnification.  The underwriting agreement contains covenants of
indemnity among the underwriters and us against specified civil liabilities,
including liabilities under the Securities Act and liabilities arising from
breaches of representations and warranties contained in the underwriting
agreement.



     Lock-up Agreement.  Each of our officers, directors and securityholders
agreed with the representatives or us for a period of 180 days, and in the case
of some securityholders 90 days, after the effective date of this prospectus,
not to dispose of or hedge any shares of common stock, or securities convertible
into or exchangeable for shares of common stock, now owned or later acquired by
them without the prior written consent of BancBoston Robertson Stephens Inc.
However, BancBoston Robertson Stephens Inc. may, in its sole discretion and at
any time without notice, release all or any portion of the securities subject to
lock-up agreements. All of the shares of common stock subject to the lock-up
agreements will be eligible for sale in the public market upon the expiration of
the lock-up agreements, subject to holding period, volume limitations and other
conditions of Rule 144.


                                       67
<PAGE>   73


     Future Sales.  In addition, we have agreed that during the 180 days
following the effective date of this prospectus, we will not, without the prior
written consent of BancBoston Robertson Stephens Inc., subject to limited
exceptions (including in connection with acquisitions), dispose of or hedge any
shares of common stock, or any securities convertible into, exercisable for or
exchangeable for shares of common stock, other than (i) our sales of shares in
this offering, (ii) the issuance of common stock upon the exercise of
outstanding options or warrants or (iii) our issuance of options or shares under
the 1994 stock purchase plan, 1997 stock plan, 1999 employee stock purchase plan
and 1999 directors' stock option plan.


     The underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.


     Determination of Offering Price.  Prior to this offering, there has been no
public market for our common stock. Consequently, the initial public offering
price for the common stock in this offering has been determined through
negotiations among us and the representatives of the underwriters. The factors
considered in these negotiations included prevailing market conditions, our
financial information, the market valuation of other companies that we and the
representatives believe to be comparable to us, estimates of our business
potential and the business potential of the industry in which we compete, an
assessment of our management, our past and present operation, the prospects for
our future revenues and other factors deemed relevant.



     Share Ownership by Underwriters.  An entity affiliated with U.S. Bancorp
Piper Jaffray Inc. purchased an aggregate of 53,996 shares of our Series C
preferred stock from us in August 1998. This affiliate is subject to the 180-day
lock-up that applies to other securityholders as described above. U.S. Bancorp
Piper Jaffray Inc. and its affiliates (other than the holder described above)
will be permitted to engage in stabilization, brokerage and ordinary course of
business transactions. See "Shares Eligible for Future Sale."



     Stabilization.  The representatives have advised us that, pursuant to
Regulation M under the Securities Act, some persons participating in the
offering may engage in transactions, including stabilizing bids, syndicate
covering transactions or the imposition of penalty bids that may have the effect
of stabilizing or maintaining the market price of the common stock at a level
above that which might otherwise prevail in the open market. A "stabilizing bid"
is a bid for or the purchase of the common stock on behalf of the underwriters
for the purpose of fixing or maintaining the price of the common stock. A
"syndicate covering transaction" is the bid for the purchase of the common stock
on behalf of the underwriters to reduce a short position incurred by the
underwriters in connection with the offering. A "penalty bid" is an arrangement
permitting the representatives to reclaim the selling concession otherwise
accruing to an underwriter or syndicate member in connection with the offering
if the common stock originally sold by such underwriter or syndicate member is
purchased by the representatives in a syndicate covering transaction and has
therefore not been effectively placed by such underwriter or syndicate member.
These transactions may be effected on the Nasdaq National Market or otherwise
and, if commenced, may be discontinued at any time.



     Reserved Shares.  The underwriters have reserved for sale at the initial
public offering price up to 5% of the common stock in this offering for
individuals designated by us who have expressed an interest in purchasing shares
of common stock in this offering. The number of shares available for sale to the
general public will be reduced to the extent these persons purchase the reserved
shares. The underwriters will offer any reserved shares


                                       68

not so purchased to the general public on the same basis as other shares in this
offering described above.



     Under an agreement among us and our principal stockholders, affiliates of
Amerindo Investment Advisors L.P. have the right to purchase up to 3% of the
shares offered in this offering. To exercise this right, these entities must
state the number of shares they intend to purchase and commit to purchase such
number within five business days after we provide them notice of this offering.

</TABLE>



     Shares sold by the underwriters will initially be offered to the public at
the initial public offering price set forth on the cover page of this
prospectus. Any shares sold by the underwriters to securities dealers may be
sold at a discount of up to      per share from the initial public offering
price. These securities dealers may resell any shares purchased from the
underwriters to other brokers or dealers at a discount of up to      per share
from the initial public offering price. If all the shares are not sold at the
initial public offering price, the representatives may change the offering price
and the other selling terms.



     Over-Allotment Option.  We have granted to the underwriters an option,
exercisable during the 30-day period after the date of this prospectus, to
purchase up to 450,000 additional shares of common stock at the same price per
share as we will receive for the 3,000,000 shares that the underwriters have
agreed to purchase. To the extent that the underwriters exercise this option,
each of the underwriters will have a firm commitment, to purchase approximately
the same percentage of such additional shares that the number of shares of
common stock to be purchased by it shown in the above table represents as a
percentage of the 3,000,000 shares in this offering. If purchased, these
additional shares will be sold by the underwriters on the same terms as those on
which the 3,000,000 shares are being sold.



     Indemnification.  The underwriting agreement contains covenants of
indemnity among the underwriters and us against specified civil liabilities,
including liabilities under the Securities Act and liabilities arising from
breaches of representations and warranties contained in the underwriting
agreement.



     Lock-up Agreement.  Each of our officers, directors and securityholders
agreed with the representatives or us for a period of 180 days, and in the case
of some securityholders 90 days, after the effective date of this prospectus,
not to dispose of or hedge any shares of common stock, or securities convertible
into or exchangeable for shares of common stock, now owned or later acquired by
them without the prior written consent of BancBoston


                                       67
<PAGE>   76


Robertson Stephens Inc. However, BancBoston Robertson Stephens Inc. may, in its
sole discretion and at any time without notice, release all or any portion of
the securities subject to lock-up agreements. All of the shares of common stock
subject to the lock-up agreements will be eligible for sale in the public market
upon the expiration of the lock-up agreements, subject to holding period, volume
limitations and other conditions of Rule 144.



     Future Sales.  In addition, we have agreed that during the 180 days
following the effective date of this prospectus, we will not, without the prior
written consent of BancBoston Robertson Stephens Inc., subject to limited
exceptions (including in connection with acquisitions), dispose of or hedge any
shares of common stock, or any securities convertible into, exercisable for or
exchangeable for shares of common stock, other than (i) our sales of shares in
this offering, (ii) the issuance of common stock upon the exercise of
outstanding options or warrants or (iii) our issuance of options or shares under
the 1994 stock purchase plan, 1997 stock plan, 1999 employee stock purchase plan
and 1999 directors' stock option plan.


     The underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.


     Determination of Offering Price.  Prior to this offering, there has been no
public market for our common stock. Consequently, the initial public offering
price for the common stock in this offering has been determined through
negotiations among us and the representatives of the underwriters. The factors
considered in these negotiations included prevailing market conditions, our
financial information, the market valuation of other companies that we and the
representatives believe to be comparable to us, estimates of our business
potential and the business potential of the industry in which we compete, an
assessment of our management, our past and present operation, the prospects for
our future revenues and other factors deemed relevant.



     Share Ownership by Underwriters.  An entity affiliated with U.S. Bancorp
Piper Jaffray Inc. purchased an aggregate of 53,996 shares of our Series C
preferred stock from us in August 1998. This affiliate is subject to the 180-day
lock-up that applies to other securityholders as described above. U.S. Bancorp
Piper Jaffray Inc. and its affiliates (other than the holder described above)
will be permitted to engage in stabilization, brokerage and ordinary course of
business transactions. See "Shares Eligible for Future Sale."



     Stabilization.  The representatives have advised us that, pursuant to
Regulation M under the Securities Act, some persons participating in the
offering may engage in transactions, including stabilizing bids, syndicate
covering transactions or the imposition of penalty bids that may have the effect
of stabilizing or maintaining the market price of the common stock at a level
above that which might otherwise prevail in the open market. A "stabilizing bid"
is a bid for or the purchase of the common stock on behalf of the underwriters
for the purpose of fixing or maintaining the price of the common stock. A
"syndicate covering transaction" is the bid for the purchase of the common stock
on behalf of the underwriters to reduce a short position incurred by the
underwriters in connection with the offering. A "penalty bid" is an arrangement
permitting the representatives to reclaim the selling concession otherwise
accruing to an underwriter or syndicate member in connection with the offering
if the common stock originally sold by such underwriter or syndicate member is
purchased by the representatives in a syndicate covering transaction and has
therefore not been effectively placed by such underwriter or syndicate member.
These transactions may be effected on the Nasdaq National Market or otherwise
and, if commenced, may be discontinued at any time.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
Persistence Software, Inc.:

     We have audited the accompanying consolidated balance sheets of Persistence
Software, Inc. and subsidiary as of December 31, 1997 and 1998, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 1998. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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, such consolidated financial statements present fairly, in
all material respects, the financial position of Persistence Software, Inc. and
subsidiary at December 31, 1997 and 1998, and the results of its operations and
its cash flows for each of the three years in the period ended December 31, 1998
in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                YEARS ENDED DECEMBER 31, 1996, 1997 AND 1998 AND
                 THREE MONTHS ENDED MARCH 31, 1999 (UNAUDITED)

1.  BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

     Business -- Persistence Software, Inc. and subsidiary (the Company),
incorporated in California in June 1991, develops and markets transactional
application server software products that comprise the Internet software
infrastructure for high-volume, high-performance electronic commerce
applications.

     Principles of Consolidation -- The consolidated financial statements
include the accounts of the Company and its wholly-owned subsidiary. All
intercompany transactions and balances have been eliminated in consolidation.

     Cash Equivalents -- The Company considers all highly liquid debt
instruments purchased with a remaining maturity of three months or less to be
cash equivalents.

     Property and equipment are stated at cost.  Depreciation and amortization
are computed using the straight-line method over estimated useful lives of three
years. Leasehold improvements are amortized over the shorter of the lease term
or their useful life.

     Impairment of Long-Lived Assets and Long-Lived Assets To Be Disposed
Of -- The Company evaluates its long-lived assets for impairment whenever events
or changes in circumstances indicate that the carrying amount of such assets or
intangibles may not be recoverable. Recoverability of assets to be held and used
is measured by a comparison of the carrying amount of an asset to future
undiscounted net cash flows expected to be generated by the asset. If such
assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the assets exceeds the
fair value of the assets. Assets to be disposed of are reported at the lower of
the carrying amount or fair value less costs to sell.

     Software Development Costs -- Costs for the development of new software
products and substantial enhancements to existing software products are expensed
as incurred until technological feasibility has been established, at which time
any additional costs would be capitalized in accordance with Statement of
Financial Accounting Standards (SFAS) No. 86, Computer Software To Be Sold,
Leased or Otherwise Marketed. Because the Company believes its current process
for developing software is essentially completed concurrently with the
establishment of technological feasibility, no costs have been capitalized to
date.

     Notes Receivable from Stockholders -- The notes receivable from
stockholders were issued in exchange for common stock, bear interest at 5.93%
per annum, and are due in December 2001.

     Revenue Recognition -- Revenue consists primarily of fees for licenses of
the Company's software products, maintenance and customer support.

          License Revenue -- Revenue from software licenses is recognized upon
     shipment of the software if collection of the resulting receivable is
     probable, an executed agreement has been signed, the fee is fixed or
     determinable and vendor-specific objective evidence exists to allocate a
     portion of the total fee to any undelivered elements of the arrangement.
     Such undelivered elements in these arrangements

                                       F-7
<PAGE>   85

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


     typically consist of services. For sales made through distributors, revenue
     is recognized upon shipment. Distributors have no right of return.



          Service Revenue -- Revenue from customer training, support and
     consulting services is recognized as the services are performed. Support
     revenue is recognized ratably over the term of the support contract. If
     support or professional services are included in an arrangement that
     includes a license agreement, amounts related to support or professional
     services are allocated based on vendor-specific objective evidence.
     Vendor-specific objective evidence for support and professional services is
     based on the price when such elements are sold separately, or, when not
     sold separately, the price established by management having the relevant
     authority. Arrangements which require significant modification or
     customization of software are recognized under the percentage of completion
     method.


     In October 1997, the American Institute of Certified Public Accountants
issued Statement of Position (SOP) 97-2, Software Revenue Recognition. This
statement provides guidance on applying generally accepted accounting principles
in recognizing revenue on software transactions and superseded SOP 91-1,
Software Revenue Recognition. SOP 97-2 was effective for transactions entered
into in 1998. The adoption of this standard did not have a material effect on
the Company's financial position or results of operations.

     Income Taxes -- Income taxes are provided using an asset and liability
approach which requires recognition of deferred tax liabilities and assets, net
of valuation allowances, for the expected future tax consequences of temporary
differences between the financial statement carrying amounts and the tax bases
of assets and liabilities and net operating loss and tax credit carryforwards.

     Foreign Currency Transactions -- The functional currency of the Company's
foreign subsidiary is the U.S. dollar. Accordingly, all monetary assets and
liabilities are translated at the current exchange rate at the end of the year,
nonmonetary assets and liabilities are translated at historical rates and net
sales and expenses are translated at average exchange rates in effect during the
period. Transaction gains and losses, which are included in other income
(expense) in the accompanying consolidated statements of operations, have not
been significant.

     Stock Compensation -- The Company accounts for stock-based awards to
employees using the intrinsic value method in accordance with Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees.
Accordingly, no accounting recognition is given to employee stock options
granted at fair market value until they are exercised. Upon exercise, the net
proceeds are credited to stockholders' equity.

     Net Loss per Common Share -- Basic net loss per common share excludes
dilution and is computed by dividing net loss by the weighted average number of
common shares outstanding for the period (excluding shares subject to
repurchase). Diluted net loss per common share was the same as basic net loss
per common share for all periods presented since the effect of any potentially
dilutive securities is excluded as they are anti-dilutive because of the
Company's net losses.

     Pro Forma Net Loss per Common Share -- Pro forma basic and diluted net loss
per common share is computed by dividing net loss by the weighted average number
of common shares outstanding for the period (excluding shares subject to
repurchase) and

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

the weighted average number of common shares resulting from the conversion of
outstanding shares of convertible preferred stock, which will occur upon the
closing of the planned initial public offering.

     Unaudited Pro Forma Information -- Upon the closing of the planned initial
public offering, each of the outstanding shares of convertible preferred stock
will convert into one share of common stock. The pro forma balance sheet
presents the Company's balance sheet as if this had occurred at March 31, 1999.

     Unaudited Interim Financial Information -- The interim financial
information as of March 31, 1999 and for the three months ended March 31, 1998
and 1999 is unaudited and has been prepared on the same basis as the audited
financial statements. In the opinion of management, such unaudited financial
information includes all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the interim information.
Operating results for the three months ended March 31, 1999 are not necessarily
indicative of the results that may be expected for the year ended December 31,
1999.

     Concentration of Credit Risk -- Financial instruments that potentially
expose the Company to concentrations of credit risk consist primarily of trade
receivables. The Company primarily sells its products to companies in the United
States and Europe. The Company does not require collateral or other security to
support accounts receivable. To reduce credit risk, management performs ongoing
credit evaluations of its customers' financial condition. The Company maintains
allowances for potential credit losses.

     Financial Instruments -- The Company's financial instruments include cash
and equivalents, notes receivable from stockholders and long-term debt. At
December 31, 1997 and 1998, the fair value of these financial instruments
approximated their financial statement carrying amounts.

     Significant Estimates -- The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets, and
liabilities and disclosures of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from these estimates.

     Certain Significant Risks and Uncertainties -- The Company operates in the
software industry, and accordingly, can be affected by a variety of factors. For
example, management of the Company believes that changes in any of the following
areas could have a significant negative effect on the Company in terms of its
future financial position, results of operations and cash flows: ability to
obtain additional financing; regulatory changes; fundamental changes in the
technology underlying software products; market acceptance of the Company's
products under development; development of sales channels; loss of significant
customers; adverse changes in international market conditions; year 2000
compliance issues; litigation or other claims against the Company; the hiring,
training and retention of key employees; successful and timely completion of
product development efforts; and new product introductions by competitors.

     Recently Issued Accounting Standards -- In June 1997, the FASB issued SFAS
No. 130, Reporting Comprehensive Income, which requires an enterprise to report,
by
                                       F-9

major components and as a single total, the change in its net assets during the
period from nonowner sources; and SFAS No. 131, Disclosures About Segments of an
Enterprise and Related Information, which establishes annual and interim
reporting standards for an enterprise's business segments and related
disclosures about its products, services, geographic areas and major customers.
The Company had no comprehensive income items, other than net loss, to report
for any of the periods presented. The Company currently operates in one
reportable segment under SFAS No. 131.

     In March 1998, the American Institute of Certified Public Accountants
issued SOP 98-1, Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use. This standard requires companies to capitalize
qualifying computer software costs, which are incurred during the application
development stage and amortize them over the software's estimated useful life.
SOP 98-1 is effective for fiscal years beginning after December 15, 1998. The
Company is currently evaluating the impact of SOP 98-1 on its financial
statements and related disclosures.

     In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. This statement requires companies to record
derivatives on the balance sheet as assets or liabilities measured at fair
value. Gains or losses resulting from changes in the values of those derivatives
would be accounted for depending on the use of the derivative and whether it
qualifies for hedge accounting. SFAS No. 133 will be effective for the Company's
fiscal year ending December 31, 2000. The Company is currently evaluating the
impact of SFAS No. 133 on its financial statements and related disclosures.

     Reclassifications -- Certain reclassifications have been made to the 1996
and 1997 financial statement presentations to conform to the 1998 presentation.

</TABLE>

     In February 1998, the Company entered into a $2,000,000 line of credit with
a bank. Borrowings under the line bear interest at the bank's base rate (7.75%
at December 31, 1998) and are limited to a percentage of eligible accounts
receivable, as defined. At December 31, 1998, there were no borrowings under the
line.

     At December 31, 1998, the Company had outstanding borrowings of $800,000
under a bank promissory note, which bears interest at 7.75%. The Company is
required to make principal payments of $22,222 per month plus interest on the
unpaid principal balance, payable in 36 monthly installments commencing April 1,
1999.

     The line of credit requires the Company, among other things, to maintain a
minimum tangible net worth of $500,000 and a quick ratio greater than 1.3 to
1.0. At December 31, 1998, the Company was in compliance with the financial
covenant requirements. Both agreements are collateralized by substantially all
of the Company's assets.

     Annual maturities under the term loan are as follows:

5.  STOCKHOLDERS' EQUITY

CONVERTIBLE PREFERRED STOCK

     Terms of the convertible preferred stock are as follows:

     - Each share of Series A, Series B and Series C preferred stock is
       convertible into one share of common stock (subject to adjustment for
       events of dilution). Each share will automatically convert into common
       stock upon the completion of a public offering with aggregate proceeds
       greater than $12,000,000 and at a price per share of not less than $7.00.

     - Each share of Series A, Series B and Series C preferred stock has voting
       rights equivalent to the number of shares of common stock into which it
       is convertible.

     - When declared by the Board of Directors, the holders of Series A
       preferred stock are entitled to receive cumulative dividends of
       $0.035797, and the holders of Series B and Series C preferred stock are
       entitled to receive noncumulative dividends of $0.1374 and $0.2778 per
       share, respectively, per annum prior to the payment of any dividends on
       common stock. At December 31, 1998, dividends in arrears for Series A
       preferred stock were approximately $373,000. However, as of December 31,
       1998, no dividends have been declared by the Board of Directors.

     - In the event of liquidation, dissolution or winding up of the Company,
       Series A, Series B and Series C preferred stockholders shall receive
       $0.59662, $2.29, and $6.945 per share, respectively (aggregating
       approximately $1,274,000, $7,427,000 and $10,725,000 at December 31,
       1998, respectively), plus all accrued but unpaid dividends; any remaining
       assets shall be distributed to the common stockholders.

     - The preferred stockholders have certain registration rights.

COMMON STOCK


     In 1996, the Company entered into an agreement with the lessor of its
principal facility to issue 110,000 shares of the Company's common stock valued
at $0.23 per share in lieu of rent payments for the twelve-month period
beginning September 1996. At December 31, 1996, 32,359 shares were subscribed
under this agreement. All 110,000 shares were issued in 1997. An expense of
$7,000 and $19,000 has been recorded in 1996 and 1997, respectively, related to
the issuance of such shares. Rent expense has been recorded on a straight-line
basis.


     During 1996 and 1997, the Company issued common stock to directors in their
capacity as consultants (see Note 8).


     In February 1999, the Company entered into an agreement with a customer and
Series D preferred stockholder, whereby such customer was to perform development
work to achieve certain performance improvements related to the Company's
PowerTier product. In connection with this agreement, the Company allowed such
customer to purchase 90,300 shares of common stock at $1.65 per share in
February 1999, which was less than the deemed fair value for accounting
purposes. The Company has recorded a research and development expense of
$303,000 in the three months ended March 31, 1999 for the difference between the
deemed fair value and the stock price of $1.65 per share.


DEFERRED STOCK COMPENSATION

     In connection with grants of certain stock options and issuance of common
stock in 1997, 1998 and in the three months ended March 31, 1999, the Company
recorded $287,000, $2,266,000 and $987,000, respectively, for the difference
between the estimated fair value and the stock price as determined by the Board
of Directors on the date of grant/issuance. This amount has been presented as a
reduction of stockholders' equity and is being amortized to expense over the
vesting period of the related stock/stock options (generally four years).
Amortization of deferred stock compensation for the year ended December 31, 1998
and three-month period ended March 31, 1999 was $331,000 and $504,000,
respectively.

1994 STOCK PURCHASE PLAN

     Under the 1994 Stock Purchase Plan (the Plan), the Company may sell common
stock to employees of the Company at the fair market value as determined by the
Board of Directors. Sales are to be made pursuant to restricted stock purchase
agreements containing provisions established by the Board. During 1996 and 1997,
the Company issued 304,325 and 212,995 shares of common stock, respectively,
under the Plan. No shares were issued under the Plan in 1998. In 1996, the
shares were issued at prices ranging from $0.06 to $0.23 per share, and in 1997
the shares were issued at $0.23 per share. The Company has the right to
repurchase these shares at the original issuance price upon termination of
employment; this right expires ratably over four years. During 1996, 1997 and
1998, the Company repurchased 281,250, 237,056 and 23,081 shares, respectively,
at prices ranging from $0.06 to $0.23 per share. At December 31, 1998, 55,697
shares were subject to repurchase and no shares were available for future grant.

1997 STOCK PLAN

     The Company has reserved 2,609,652 shares of common stock for issuance, at
the discretion of the Board of Directors, to officers, directors, employees and
consultants pursuant to its 1997 Stock Plan. At December 31, 1998, 796,487
shares have been issued at $0.23 per share pursuant to restricted stock purchase
agreements, 1,238,072 shares are reserved for exercise of issued and outstanding
options, and 570,339 shares are available for future grant. The Company has a

SFAS No. 123, Accounting for Stock-Based Compensation, requires the disclosure
of pro forma net loss had the Company adopted the fair value method as of the
beginning of fiscal 1995. Under SFAS No. 123, the fair value of stock-based
awards to employees is calculated through the use of option pricing models, even
though such models were developed to estimate the fair value of freely tradable,
fully transferable options without vesting restrictions, which significantly
differ from the Company's stock option awards. These models also require
subjective assumptions, including future stock price volatility and expected
time to exercise, which greatly affect the calculated values. The Company's
calculations were made using the minimum value option pricing model with the
following weighted average assumptions: expected life, 24 months following
vesting in 1997 and 1998; risk free interest rate, 6.0% in 1997 and 5.5% in
1998; and no dividends during the expected term. The Company's calculations are
based on a multiple option valuation approach and forfeitures are recognized as
they occur. If the computed fair values of the 1997 and 1998 awards had been
amortized to expense over the vesting period of the awards, pro forma net loss
(net of amortization of deferred compensation expense already recorded for the
year ended December 31, 1998, as discussed above) would have been approximately
$4.7 million ($0.73 per basic and diluted share) in 1997 and $4.4 million ($0.63
per basic and diluted share) in 1998.

WARRANTS


     In December 1995, in conjunction with a capital lease agreement (see Note
3), the Company issued a warrant to purchase up to 55,556 shares of common stock
at $0.90 per share. The warrant expires in December 2001. In February 1996, in
connection with a line of credit agreement with a bank, a warrant was issued to
the bank to purchase up to 25,000 shares of common stock at $0.90 per share. The
warrant expires in February 2001. The line of credit expired in April 1997. The
aggregate fair value of such warrants was insignificant.

     Deferred income taxes reflect the tax effects of temporary differences
between the carrying amount of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes, as well as net operating
loss and tax credit carryforwards. Due to the uncertainty surrounding the
realization of the benefits of its favorable tax attributes in future tax
returns, as of December 31, 1997 and 1998, the Company has fully reserved its
net deferred tax assets of approximately $3,504,000 and $6,063,000,
respectively.

     The Company's effective rate differs from the expected benefit at the
federal statutory tax rate at December 31 as follows:

</TABLE>



     Substantially all of the Company's loss from operations for all periods
presented is generated from domestic operations.


     At December 31, 1998, the Company has net operating loss (NOL)
carryforwards of approximately $10,840,000 and $3,606,000 for federal and state
income tax purposes, respectively. The federal NOL carryforwards expire through
2018, while the state NOL carryforwards expire through 2003. The net operating
loss carryforwards available for state tax purposes are substantially less than
for federal tax purposes, primarily because only 50% of state net operating
losses can be utilized to offset future state taxable income.

     At December 31, 1998, the Company also has research and development credit
carryforwards of approximately $570,000 and $320,000 available to offset future
federal and state income taxes, respectively. The federal credit carryforward
expires in 2018, while the state credit carryforward has no expiration.

     The extent to which the loss and credit carryforwards can be used to offset
future taxable income and tax liabilities, respectively, may be limited,
depending on the extent of ownership changes within any three-year period.

8.  RELATED PARTY TRANSACTIONS

     During 1996, the Company recognized revenue of $24,000 from a stockholder.
Also during 1996, the Company entered into a technology development and license
agreement with a stockholder. Such stockholder paid the Company a purchase
advance of $50,000 and granted the Company a source code license to incorporate
specific technology into products developed for such stockholder and other
commercial uses.

     During 1997, the Company recognized revenue of $300,000 and $250,000 from a
Series B and a Series C preferred stockholder, respectively. At December 31,
1997, the Company had deferred revenue of $750,000 from the same Series C
preferred stockholder.


     During 1998, the Company recognized revenue of $168,000 and $1,450,000 from
a Series B and a Series C preferred stockholder, respectively. At December 31,
1998, the Company had deferred revenue of $30,000 and $642,000 with the same
Series B and Series C preferred stockholders, respectively. At December 31,
1998, the Company had accounts receivable of $101,000 from the Series B
preferred stockholder.

the date of sale. In July 1998, the Company granted a fully vested option to
purchase up to 3,572 shares of common stock at $0.50 per share to a director in

11.  SUBSEQUENT EVENTS


     In February and March 1999, the Company received net proceeds of
approximately $4,142,000 from the sale of 775,701 shares of Series D preferred
stock at $5.35 per share. Also, in February 1999, the Company sold 90,300 shares
of common stock to a customer and Series D preferred stockholder at $1.65 per
share. The Series D preferred stockholders are entitled to receive noncumulative
dividends of $0.321 per share per annum when declared by the Board of Directors
prior to the payment of any dividends on common stock. In the event of
liquidation, dissolution or winding up of the Company, Series D preferred
stockholders will receive a liquidation preference of $5.35 per share
(aggregating approximately $4,150,000) plus all accrued and unpaid dividends.
Other significant terms of the Series D preferred stock regarding conversion to
common stock, voting rights and registration rights are similar to those
described in the Note 5.


     In April 1999, the Board of Directors approved, subject to stockholder
approval, the following:

        - Reincorporation of the Company in the state of Delaware.

        - An amendment to the 1997 Stock Plan to increase the number of
          authorized shares reserved for issuance by 3,000,000 and to provide
          for an automatic annual increase on the first day of each fiscal year
          beginning in 2001, 2002, 2003, 2004 and 2005 equal to the lesser of
          650,000 shares, 3.5% of the outstanding common stock on the last day
          of the immediately preceding fiscal year, or such lesser number as
          determined by the Board of Directors. The amendment is effective upon
          the closing of the Company's initial public offering.

        - The Company's 1999 Employee Stock Purchase Plan (the "ESPP") and the
          1999 Directors' Stock Option Plan (the "Directors' Plan"). The Plans
          become effective upon the closing of the Company's initial public
          offering. Under the ESPP, eligible employees may purchase common stock
          through payroll deductions, which may not exceed 20% of any employee's
          compensation, nor more than 2,500 shares in any one purchase period. A
          total of 600,000 shares of common stock will be reserved for issuance
          under the ESPP plus an automatic annual increase on the first day of
          each of the fiscal years beginning in 2000, 2001, 2002, 2003 and 2004
          equal to the lessor of 250,000 shares or 1% of outstanding common
          stock on the last day of the immediately preceding fiscal year. Under
          the Directors' Plan, a total of 500,000 shares of common stock has
          been reserved for the grant of nonstatutory stock options to
          nonemployee directors of the Company. Options granted under the
          Director's Plan shall be immediately vested and expire in five years
          from the date of grant.

        - An increase of authorized shares of common stock to 75,000,000 shares
          and creation of newly undesignated preferred stock totaling 5,000,000
          shares, contingent upon the approval of the reincorporation of the
          Company in Delaware and the closing of the Company's initial public
          offering.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS


     Section 145 of the Delaware General Corporation Law (the "Delaware Law")
authorizes a court to award, or a corporation's board of directors to grant,
indemnity 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 XIII of our certificate of
incorporation (Exhibit 3.2) and Article VI of our bylaws (Exhibit 3.4) provide
for indemnification of our directors, officers, employees and other agents to
the maximum extent permitted by Delaware Law. In addition, we have entered into
indemnification agreements (Exhibit 10.11) with our officers and directors. The
underwriting agreement (Exhibit 1.1) also provides for cross-indemnification
among us and the underwriters with respect to matters specified in the
agreements, including matters arising under the Securities Act.

ITEM 17.  UNDERTAKINGS

     The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, 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 Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer, or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

          The undersigned registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon 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 of 1933, 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.

                                   SIGNATURES


     Pursuant to the requirements of the Securities Act of 1933, the registrant
has duly caused this Amendment to the Registration Statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in the city of San Mateo,
State of California, on June 2, 1999.

                                  June __, 1999


BancBoston Robertson Stephens Inc.
U.S. Bancorp Piper Jaffray Inc.
SoundView Technology Group, Inc.
As Representatives of the several Underwriters
c/o BancBoston Robertson Stephens Inc.
555 California Street, Suite 2600
San Francisco, CA  94104


Ladies and Gentlemen:

                  INTRODUCTORY. Persistence Software, Inc., a Delaware
corporation (the "Company), proposes to issue and sell to the several
underwriters named in Schedule A (the "Underwriters") an aggregate of [___]
shares (the "Firm Shares") of its Common Stock, par value $0.001 per share (the
"Common Shares"). In addition, the Company has granted to the Underwriters an
option to purchase up to an additional [___] Common Shares (the "Option Shares")
as provided in Section 2. The Firm Shares and, if and to the extent such option
is exercised, the Option Shares are collectively called the "Shares". BancBoston
Robertson Stephens Inc., U.S. Bancorp Piper Jaffray Inc. and SoundView
Technology Group, Inc. have agreed to act as representatives of the several
Underwriters (in such capacity, the "Representatives") in connection with the
offering and sale of the Shares.

                  The Company has prepared and filed with the Securities and
Exchange Commission (the "Commission") a registration statement on Form S-1
(File No. 333-76867), which contains a form of prospectus to be used in
connection with the public offering and sale of the Shares. Such registration
statement, as amended, including the financial statements, exhibits and
schedules thereto, in the form in which it was declared effective by the
Commission under the Securities Act of 1933 and the rules and regulations
promulgated thereunder (collectively, the "Securities Act"), including any
information deemed to be a part thereof at the time of effectiveness pursuant to
Rule 430A or Rule 434 under the Securities Act, is called the "Registration
Statement". Any registration statement filed by the Company pursuant to Rule
462(b) under the Securities Act is called the "Rule 462(b) Registration
Statement", and from and after the date and time of filing of the Rule 462(b)
Registration Statement the term "Registration Statement" shall include the Rule
462(b) Registration Statement. Such prospectus, in the form first used by the
Underwriters to confirm sales of the Shares, is called the "Prospectus";
provided, however, if the Company has, with the consent of BancBoston Robertson
Stephens Inc., elected to rely upon Rule 434 under the Securities Act, the term
"Prospectus" shall mean the Company's prospectus subject to completion (each, a
"preliminary prospectus") dated ____________, 1999 (such preliminary prospectus
is called the "Rule 434 preliminary prospectus"), together with the applicable
term sheet (the "Term Sheet") prepared
<PAGE>   2
and filed by the Company with the Commission under Rules 434 and 424(b) under
the Securities Act and all references in this Agreement to the date of the
Prospectus shall mean the date of the Term Sheet. All references in this
Agreement to the Registration Statement, the Rule 462(b) Registration Statement,
a preliminary prospectus, the Prospectus or the Term Sheet, or any amendments or
supplements to any of the foregoing, shall include any copy thereof filed with
the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval
System ("EDGAR").

             The Company hereby confirms its agreements with the Underwriters as
follows:

         SECTION 1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
hereby represents, warrants and covenants to each Underwriter as follows:

         (a) Compliance with Registration Requirements. The Registration
Statement and any Rule 462(b) Registration Statement have been declared
effective by the Commission under the Securities Act. The Company has complied
to the Commission's satisfaction with all requests of the Commission for
additional or supplemental information. No stop order suspending the
effectiveness of the Registration Statement or any Rule 462(b) Registration
Statement is in effect and no proceedings for such purpose have been instituted
or are pending or, to the best knowledge of the Company, are contemplated or
threatened by the Commission.

             Each preliminary prospectus and the Prospectus when filed complied
in all material respects with the Securities Act and, if filed by electronic
transmission pursuant to EDGAR (except as may be permitted by Regulation S-T
under the Securities Act), was identical to the copy thereof delivered to the
Underwriters for use in connection with the offer and sale of the Shares. Each
of the Registration Statement, any Rule 462(b) Registration Statement and any
post-effective amendment thereto, at the time it became effective and at all
subsequent times, complied and will comply in all material respects with the
Securities Act and did not and will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading. The Prospectus, as
amended or supplemented, as of its date and at all subsequent times, did not and
will not contain any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading. The
representations and warranties set forth in the two immediately preceding
sentences do not apply to statements in or omissions from the Registration
Statement, any Rule 462(b) Registration Statement, or any post-effective
amendment thereto, or the Prospectus, or any amendments or supplements thereto,
made in reliance upon and in conformity with information relating to any
Underwriter furnished to the Company in writing by the Representatives expressly
for use therein. There are no contracts or other documents required to be
described in the Prospectus or to be filed as exhibits to the Registration
Statement which have not been described or filed as required.

         (b) Offering Materials Furnished to Underwriters. The Company has
delivered to each Representative one complete conformed copy of the Registration
Statement and of each consent and certificate of experts filed as a part
thereof, and conformed copies of the Registration Statement (without exhibits)
and preliminary prospectuses and the Prospectus, as amended or supplemented, in
such quantities and at such places as the Representatives have reasonably
requested for each of the Underwriters.

         (c) Distribution of Offering Material By the Company. The Company has
not distributed and will not distribute, prior to the later of the Second
Closing Date (as defined


                                       2.

below) and the completion of the Underwriters' distribution of the Shares, any
offering material in connection with the offering and sale of the Shares other
than a preliminary prospectus, the Prospectus or the Registration Statement.

         (d) The Underwriting Agreement. This Agreement has been duly
authorized, executed and delivered by, and is a valid and binding agreement of,
the Company, enforceable in accordance with its terms, except as rights to
indemnification hereunder may be limited by applicable law and except as the
enforcement hereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to or affecting the rights and
remedies of creditors or by general equitable principles.

         (e) Authorization of the Shares to Be Sold by the Company. The Shares
to be purchased by the Underwriters from the Company have been duly authorized
for issuance and sale pursuant to this Agreement and, when issued and delivered
by the Company pursuant to this Agreement, will be validly issued, fully paid
and nonassessable.

         (f) No Applicable Registration or Other Similar Rights. There are no
persons with registration or other similar rights to have any equity or debt
securities registered for sale under the Registration Statement or included in
the offering contemplated by this Agreement, except for such rights as have been
duly waived.

         (g) No Material Adverse Change. Subsequent to the respective dates as
of which information is given in the Prospectus: (i) there has been no material
adverse change, or any development that could reasonably be expected to result
in a material adverse change, in the condition, financial or otherwise, or in
the earnings, business, operations or prospects, whether or not arising from
transactions in the ordinary course of business, of the Company and its
subsidiaries, considered as one entity (any such change or effect, where the
context so requires, is called a "Material Adverse Change" or a "Material
Adverse Effect"); (ii) the Company and its subsidiaries, considered as one
entity, have not incurred any material liability or obligation, indirect, direct
or contingent, not in the ordinary course of business nor entered into any
material transaction or agreement not in the ordinary course of business; and
(iii) there has been no dividend or distribution of any kind declared, paid or
made by the Company or, except for dividends paid to the Company or other
subsidiaries, any of its subsidiaries on any class of capital stock or
repurchase or redemption by the Company or any of its subsidiaries of any class
of capital stock.

         (h) Independent Accountants. Deloitte & Touche, LLP, who have expressed
their opinion with respect to the financial statements (which term as used in
this Agreement includes the related notes thereto) and supporting schedules
filed with the Commission as a part of the Registration Statement and included
in the Prospectus, are independent public or certified public accountants as
required by the Securities Act.

         (i) Preparation of the Financial Statements. The financial statements
filed with the Commission as a part of the Registration Statement and included
in the Prospectus present fairly the consolidated financial position of the
Company and its subsidiaries as of and at the dates indicated and the results of
their operations and cash flows for the periods specified. The supporting
schedules included in the Registration Statement present fairly the information
required to be stated therein. Such financial statements and supporting
schedules have been prepared in conformity with generally accepted accounting
principles as applied in the United States applied on a consistent basis
throughout the periods involved, except as may be expressly stated in the
related notes thereto. No other financial statements or supporting


                                       3.
<PAGE>   4
schedules are required to be included in the Registration Statement. The
financial data set forth in the Prospectus under the captions "Prospectus
Summary -- Summary Selected Financial Data", "Selected Financial Data" and
"Capitalization" fairly present the information set forth therein on a basis
consistent with that of the audited financial statements contained in the
Registration Statement.

         (j) Company's Accounting System. The Company and each of its
subsidiaries maintain a system of accounting controls sufficient to provide
reasonable assurances that (i) transactions are executed in accordance with
management's general or specific authorization; (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with
generally accepted accounting principles as applied in the United States and to
maintain accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorization; and (iv) the
recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

         (k) Subsidiaries of the Company. The Company does not own or control,
directly or indirectly, any corporation, association or other entity other than
the subsidiaries listed in Exhibit 21.1 to the Registration Statement.

         (l) Incorporation and Good Standing of the Company and its
Subsidiaries. Each of the Company and its subsidiaries has been duly organized
and is validly existing as a corporation or limited liability company, as the
case may be, in good standing under the laws of the jurisdiction in which it is
organized with full corporate power and authority to own its properties and
conduct its business as described in the prospectus, and is duly qualified to do
business as a foreign corporation and is in good standing under the laws of each
jurisdiction which requires such qualification.

         (m) Capitalization of the Subsidiaries. All the outstanding shares of
capital stock of each subsidiary have been duly and validly authorized and
issued and are fully paid and nonassessable, and, except as otherwise set forth
in the Prospectus, all outstanding shares of capital stock of the subsidiaries
are owned by the Company either directly or through wholly owned subsidiaries
free and clear of any security interests, claims, liens or encumbrances.

         (n) No Prohibition on Subsidiaries from Paying Dividends or Making
Other Distributions. No subsidiary of the Company is currently prohibited,
directly or indirectly, from paying any dividends to the Company, from making
any other distribution on such subsidiary's capital stock, from repaying to the
Company any loans or advances to such subsidiary from the Company or from
transferring any of such subsidiary's property or assets to the Company or any
other subsidiary of the Company, except as described in or contemplated by the
Prospectus.

         (o) Capitalization and Other Capital Stock Matters. The authorized,
issued and outstanding capital stock of the Company is as set forth in the
Prospectus under the caption "Capitalization" (other than for subsequent
issuances, if any, pursuant to employee benefit plans described in the
Prospectus or upon exercise of outstanding options described in the Prospectus).
The Common Shares (including the Shares) conform in all material respects to the
description thereof contained in the Prospectus. All of the issued and
outstanding Common Shares have been duly authorized and validly issued, are
fully paid and nonassessable and have been issued in compliance with federal and
state securities laws. None of the outstanding Common Shares were issued in
violation of any preemptive rights, rights of first refusal or other


                                       4.
<PAGE>   5
similar rights to subscribe for or purchase securities of the Company. There are
no authorized or outstanding options, warrants, preemptive rights, rights of
first refusal or other rights to purchase, or equity or debt securities
convertible into or exchangeable or exercisable for, any capital stock of the
Company or any of its subsidiaries other than those accurately described in the
Prospectus. The description of the Company's stock option, stock bonus and other
stock plans or arrangements, and the options or other rights granted thereunder,
set forth in the Prospectus accurately and fairly presents the information
required to be shown with respect to such plans, arrangements, options and
rights.

         (p) Stock Exchange Listing. The Shares have been approved for inclusion
on the Nasdaq National Market, subject only to official notice of issuance.

         (q) No Consents, Approvals or Authorizations Required. No consent,
approval, authorization, filing with or order of any court or governmental
agency or regulatory body is required in connection with the transactions
contemplated herein, except such as have been obtained or made under the
Securities Act and such as may be required (i) under the blue sky laws of any
jurisdiction in connection with the purchase and distribution of the Shares by
the Underwriters in the manner contemplated here and in the Prospectus, (ii) by
the National Association of Securities Dealers, LLC and (iii) by the federal and
provincial laws of Canada.

         (r) Non-Contravention of Existing Instruments Agreements. Neither the
issue and sale of the Shares nor the consummation of any other of the
transactions herein contemplated nor the fulfillment of the terms hereof will
conflict with, result in a breach or violation or imposition of any lien, charge
or encumbrance upon any property or assets of the Company or any of its
subsidiaries pursuant to, (i) the charter or by-laws of the Company or any of
its subsidiaries, (ii) the terms of any indenture, contract, lease, mortgage,
deed of trust, note agreement, loan agreement or other agreement, obligation,
condition, covenant or instrument to which the Company or any of its
subsidiaries is a party or bound or to which its or their property is subject or
(iii) any statute, law, rule, regulation, judgment, order or decree applicable
to the Company or any of its subsidiaries of any court, regulatory body,
administrative agency, governmental body, arbitrator or other authority having
jurisdiction over the Company or any of its subsidiaries or any of its or their
properties.

         (s) No Defaults or Violations. Neither the Company nor any subsidiary
is in violation or default of (i) any provision of its charter or by-laws, (ii)
the terms of any indenture, contract, lease, mortgage, deed of trust, note
agreement, loan agreement or other agreement, obligation, condition, covenant or
instrument to which it is a party or bound or to which its property is subject
or (iii) any statute, law, rule, regulation, judgment, order or decree of any
court, regulatory body, administrative agency, governmental body, arbitrator or
other authority having jurisdiction over the Company or such subsidiary or any
of its properties, as applicable, except any such violation or default which
would not, singly or in the aggregate, result in a Material Adverse Change
except as otherwise disclosed in the Prospectus.

         (t) No Actions, Suits or Proceedings. Except as otherwise disclosed in
the Prospectus, no action, suit or proceeding by or before any court or
governmental agency, authority or body or any arbitrator involving the Company
or any of its subsidiaries or its or their property is pending or, to the best
knowledge of the Company, threatened that (i) could reasonably be expected to
have a Material Adverse Effect on the performance of this Agreement or the
consummation of any of the transactions contemplated hereby or (ii) could
reasonably be expected to result in a Material Adverse Effect.


                                       5.
<PAGE>   6
         (u) All Necessary Permits, Etc. Except as otherwise disclosed in the
Prospectus, the Company and each subsidiary possess such valid and current
certificates, authorizations or permits issued by the appropriate state, federal
or foreign regulatory agencies or bodies necessary to conduct their respective
businesses, and neither the Company nor any subsidiary has received any notice
of proceedings relating to the revocation or modification of, or non-compliance
with, any such certificate, authorization or permit which, singly or in the
aggregate, if the subject of an unfavorable decision, ruling or finding, could
result in a Material Adverse Change.

         (v) Title to Properties. Except as otherwise disclosed in the
Prospectus, the Company and each of its subsidiaries has good and marketable
title to all the properties and assets reflected as owned in the financial
statements referred to in Section 1(i) above (or elsewhere in the Prospectus),
in each case free and clear of any security interests, mortgages, liens,
encumbrances, equities, claims and other defects, except such as do not
materially and adversely affect the value of such property and do not materially
interfere with the use made or proposed to be made of such property by the
Company or such subsidiary. The real property, improvements, equipment and
personal property held under lease by the Company or any subsidiary are held
under valid and enforceable leases, with such exceptions as are not material and
do not materially interfere with the use made or proposed to be made of such
real property, improvements, equipment or personal property by the Company or
such subsidiary.

         (w) Tax Law Compliance. The Company and its subsidiaries have filed all
necessary federal, state and foreign income and franchise tax returns and have
paid all taxes required to be paid by any of them and, if due and payable, any
related or similar assessment, fine or penalty levied against any of them. The
Company has made adequate charges, accruals and reserves in the applicable
financial statements referred to in Section 1(i) above in respect of all
federal, state and foreign income and franchise taxes for all periods as to
which the tax liability of the Company or any of its subsidiaries has not been
finally determined. The Company is not aware of any tax deficiency that has been
or might be asserted or threatened against the Company that could result in a
Material Adverse Change.

         (x) Intellectual Property Rights. Each of the Company and its
subsidiaries owns or possesses adequate rights to use all patents, patent rights
or licenses, inventions, collaborative research agreements, trade secrets,
know-how, trademarks, service marks, trade names and copyrights which are
necessary to conduct its businesses as described in the Registration Statement
and Prospectus; the expiration of any patents, patent rights, trade secrets,
trademarks, service marks, trade names or copyrights would not result in a
Material Adverse Change that is not otherwise disclosed in the Prospectus; the
Company has not received any notice of, and has no knowledge of, any
infringement of or conflict with asserted rights of the Company by others with
respect to any patent, patent rights, inventions, trade secrets, know-how,
trademarks, service marks, trade names or copyrights; and the Company has not
received any notice of, and has no knowledge of, any infringement of or conflict
with asserted rights of others with respect to any patent, patent rights,
inventions, trade secrets, know-how, trademarks, service marks, trade names or
copyrights which, singly or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, might have a Material Adverse Change. There is no
claim being made against the Company regarding patents, patent rights or
licenses, inventions, collaborative research, trade secrets, know-how,
trademarks, service marks, trade names or copyrights. The Company and its
subsidiaries do not in the conduct of their business as now or proposed to be
conducted as described in the Prospectus infringe or conflict with any right or
patent of any third party, or any discovery, invention, product or process which
is the subject of a patent application filed by any third party, known to the
Company or any of its


                                       6.
<PAGE>   7
subsidiaries, which such infringement or conflict is reasonably likely to result
in a Material Adverse Change.

         (y)  Year 2000 Preparedness. There are no issues related to the
Company's, or any of its subsidiaries', preparedness for the Year 2000 that (i)
are of a character required to be described or referred to in the Registration
Statement or Prospectus by the Securities Act which have not been accurately
described in the Registration Statement or Prospectus, or (ii) might reasonably
be expected to result in any Material Adverse Change or that might materially
affect their properties, assets or rights. All internal computer systems and
each Constituent Component (as defined below) of those systems and all
computer-related products and each Constituent Component (as defined below) of
those products of the Company and each of its subsidiaries fully comply with
Year 2000 Qualification Requirements. "Year 2000 Qualifications Requirements"
means that the internal computer systems and each Constituent Component (as
defined below) of those systems and all computer-related products and each
Constituent Component (as defined below) of those products of the Company and
each of its Subsidiaries (i) have been reviewed to confirm that they store,
process (including sorting and performing mathematical operations, calculations
and computations), input and output data containing date and information
correctly regardless of whether the date contains dates and times before, on or
after January 1, 2000, (ii) have been designated to ensure date and time entry
recognition and calculations, and date data interface values that reflect the
century, (iii) accurately manage and manipulate data involving dates and times,
including single century formulas and multi-century formulas, and will not cause
an abnormal ending scenario within the application or generate incorrect values
or invalid results involving such dates, (iv) accurately process any date
rollover, and (v) accept and respond to two-digit year date input in a manner
that resolves any ambiguities as to the century. "Constituent Component" means
all software (including operating systems, programs, packages and utilities),
firmware, hardware, networking components, and peripherals provided as part of
the configuration. The Company has inquired of material vendors as to their
preparedness for the Year 2000 and has disclosed in the Registration Statement
or Prospectus any issues that might reasonably be expected to result in any
Material Adverse Change.

         (z)  No Transfer Taxes or Other Fees. There are no transfer taxes or
other similar fees or charges under Federal law or the laws of any state, or any
political subdivision thereof, required to be paid in connection with the
execution and delivery of this Agreement or the issuance and sale by the Company
of the shares.

         (aa) Company Not an "Investment Company". The Company has been advised
of the rules and requirements under the Investment Company Act of 1940, as
amended (the "Investment Company Act"). The Company is not, and after receipt of
payment for the Shares will not be, an "investment company" or an entity
"controlled" by an "investment company" within the meaning of the Investment
Company Act and will conduct its business in a manner so that it will not become
subject to the Investment Company Act.

         (bb) Insurance. Each of the Company and its subsidiaries are insured by
recognized, financially sound and reputable institutions with policies in such
amounts and with such deductibles and covering such risks as are generally
deemed adequate and customary for their businesses including, but not limited
to, policies covering real and personal property owned or leased by the Company
and its subsidiaries against theft, damage, destruction, acts of vandalism and
earthquakes, general liability and Directors and Officers liability. The Company
has no reason to believe that it or any subsidiary will not be able (i) to renew
its existing insurance coverage as and when such policies expire or (ii) to
obtain comparable coverage from


                                       7.
<PAGE>   8
similar institutions as may be necessary or appropriate to conduct its business
as now conducted and at a cost that would not result in a Material Adverse
Change. Neither of the Company nor any subsidiary has been denied any insurance
coverage which it has sought or for which it has applied.

         (cc) Labor Matters. To the best of Company's knowledge, no labor
disturbance by the employees of the Company or any of its subsidiaries exists or
is imminent; and the Company is not aware of any existing or imminent labor
disturbance by the employees of any of its principal suppliers, subassemblers,
value added resellers, subcontractors, original equipment manufacturers,
authorized dealers or international distributors that might be expected to
result in a Material Adverse Change.

         (dd) No Price Stabilization or Manipulation. The Company has not taken
and will not take, directly or indirectly, any action designed to or that might
be reasonably expected to cause or result in stabilization or manipulation of
the price of the Common Stock to facilitate the sale or resale of the Shares.

         (ee) Lock-Up Agreements. Each officer and director of the company and
each beneficial owner of one or more percent of the outstanding issued share
capital of the Company has agreed to sign an agreement substantially in the form
attached hereto as Exhibit A (the "Lock-up Agreements"). The Company has
provided to counsel for the Underwriters a complete and accurate list of all
securityholders of the Company and the number and type of securities held by
each securityholder. The Company has provided to counsel for the Underwriters
true, accurate and complete copies of all of the Lock-up Agreements presently in
effect or effected hereby. The Company hereby represents and warrants and agrees
that it will not release any of its officers, directors or other securityholders
from any Lock-up Agreements currently existing or hereafter effected, without
the prior written consent of BancBoston Robertson Stephens Inc.

         (ff) Related Party Transactions. There are no business relationships or
related-party transactions involving the Company or any subsidiary or any other
person required to be described in the Prospectus which have not been described
as required.

              Any certificate signed by an officer of the Company and delivered
to the Representatives or to counsel for the Underwriters shall be deemed to be
a representation and warranty by the Company to each Underwriter as to the
matters set forth therein.

         (gg) No Unlawful Contributions or Other Payments. Neither the Company
nor any of its subsidiaries nor, to the best of the Company's knowledge, any
employee or agent of the Company or any subsidiary, has made any contribution or
other payment to any official of, or candidate for, any federal, state or
foreign office in violation of any law or of the character required to be
disclosed in the Prospectus.

         (hh) Environmental Laws. (i) the Company is in compliance with all
rules, laws and regulations relating to the use, treatment, storage and disposal
of toxic substances and protection of health or the environment ("Environmental
Laws") which are applicable to its business, except where the failure to comply
would not result in a Material Adverse Change, (ii) the Company has received no
notice from any governmental authority or third party of an asserted claim under
Environmental Laws, which claim is required to be disclosed in the Registration
Statement and the Prospectus, (iii) the Company will not be required to make
future material capital expenditures to comply with Environmental Laws and (iv)
no property which is owned, leased or occupied by the Company has been
designated as a Superfund site pursuant


                                       8.
<PAGE>   9
to the Comprehensive Response, Compensation, and Liability Act of 1980, as
amended (42 U.S.C. Section 9601, et seq.), or otherwise designated as a
contaminated site under applicable state or local law.

         (ii) ERISA Compliance. The Company and its subsidiaries and any
"employee benefit plan" (as defined under the Employee Retirement Income
Security Act of 1974, as amended, and the regulations and published
interpretations thereunder (collectively, "ERISA")) established or maintained by
the Company, its subsidiaries or their "ERISA Affiliates" (as defined below) are
in compliance in all material respects with ERISA. "ERISA Affiliate" means, with
respect to the Company or a subsidiary, any member of any group of organizations
described in Sections 414(b),(c),(m) or (o) of the Internal Revenue Code of
1986, as amended, and the regulations and published interpretations thereunder
(the "Code") of which the Company or such subsidiary is a member. No "reportable
event" (as defined under ERISA) has occurred or is reasonably expected to occur
with respect to any "employee benefit plan" established or maintained by the
Company, its subsidiaries or any of their ERISA Affiliates. No "employee benefit
plan" established or maintained by the Company, its subsidiaries or any of their
ERISA Affiliates, if such "employee benefit plan" were terminated, would have
any "amount of unfounded benefit liabilities" (as defined under ERISA). Neither
the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or
reasonably expects to incur any liability under (i) Title IV of ERISA with
respect to termination of, or withdrawal from, any "employee benefit plan" or
(ii) Sections 412, 4971, 4975 or 4980B of the Code. Each "employee benefit plan"
established or maintained by the Company, its subsidiaries or any of their ERISA
Affiliates that is intended to be qualified under Section 401(a) of the Code is
so qualified and nothing has occurred, whether by action or failure to act,
which would cause the loss of such qualification.

         SECTION 2. PURCHASE, SALE AND DELIVERY OF THE SHARES.

         (a)  The Firm Shares. The Company agrees to issue and sell to the
several Underwriters the Firm Shares upon the terms herein set forth. On the
basis of the representations, warranties and agreements herein contained, and
upon the terms but subject to the conditions herein set forth, the Underwriters
agree, severally and not jointly, to purchase from the Company the respective
number of Firm Shares set forth opposite their names on Schedule A. The purchase
price per Firm Share to be paid by the several Underwriters to the Company shall
be $___ per share.

         (b)  The First Closing Date. Delivery of the Firm Shares to be
purchased by the Underwriters and payment therefor shall be made by the Company
and the Representatives at 6:00 a.m. San Francisco time, at the offices of
Venture Law Group, 2775 Sand Hill Road, Menlo Park, CA 94025 (or at such other
place as may be agreed upon among the Representatives and the Company), (i) on
the third (3rd) full business day following the first day that Shares are
traded, (ii) if this Agreement is executed and delivered after 1:30 P.M., San
Francisco time, the fourth (4th) full business day following the day that this
Agreement is executed and delivered or (iii) at such other time and date not
later that seven (7) full business days following the first day that Shares are
traded as the Representatives and the Company may determine (or at such time and
date to which payment and delivery shall have been postponed pursuant to Section
8 hereof), such time and date of payment and delivery being herein called the
"Closing Date;" provided, however, that if the Company has not made available to
the Representatives copies of the Prospectus within the time provided in Section
2(g) hereof, the Representatives may, in their sole discretion, postpone the
Closing Date until no later than two (2) full business days following delivery
of copies of the Prospectus to the Representatives.


                                       9.
<PAGE>   10
         (c) The Option Shares; the Second Closing Date. In addition, on the
basis of the representations, warranties and agreements herein contained, and
upon the terms but subject to the conditions herein set forth, the Company
hereby grants an option to the several Underwriters to purchase, severally and
not jointly, up to an aggregate of [___] Option Shares from the Company at the
purchase price per share to be paid by the Underwriters for the Firm Shares. The
option granted hereunder is for use by the Underwriters solely in covering any
over-allotments in connection with the sale and distribution of the Firm Shares.
The option granted hereunder may be exercised at any time upon notice by the
Representatives to the Company, which notice may be given at any time within 30
days from the date of this Agreement. The time and date of delivery of the
Option Shares, if subsequent to the First Closing Date, is called the "Second
Closing Date" and shall be determined by the Representatives and shall not be
earlier than three nor later than five full business days after delivery of such
notice of exercise. If any Option Shares are to be purchased, each Underwriter
agrees, severally and not jointly, to purchase the number of Option Shares
(subject to such adjustments to eliminate fractional shares as the
Representatives may determine) that bears the same proportion to the total
number of Option Shares to be purchased as the number of Firm Shares set forth
on Schedule A opposite the name of such Underwriter bears to the total number of
Firm Shares. The Representatives may cancel the option at any time prior to its
expiration by giving written notice of such cancellation to the Company.

         (d) Public Offering of the Shares. The Representatives hereby advise
the Company that the Underwriters intend to offer for sale to the public, as
described in the Prospectus, their respective portions of the Shares as soon
after this Agreement has been executed and the Registration Statement has been
declared effective as the Representatives, in their sole judgment, have
determined is advisable and practicable.

         (e) Payment for the Shares. Payment for the Shares shall be made at the
First Closing Date (and, if applicable, at the Second Closing Date) by wire
transfer in immediately available-funds to the order of the Company.

             It is understood that the Representatives have been authorized,
for their own account and the accounts of the several Underwriters, to accept
delivery of and receipt for, and make payment of the purchase price for, the
Firm Shares and any Option Shares the Underwriters have agreed to purchase.
BancBoston Robertson Stephens Inc., individually and not as a Representative of
the Underwriters, may (but shall not be obligated to) make payment for any
Shares to be purchased by any Underwriter whose funds shall not have been
received by the Representatives by the First Closing Date or the Second Closing
Date, as the case may be, for the account of such Underwriter, but any such
payment shall not relieve such Underwriter from any of its obligations under
this Agreement.

         (f) Delivery of the Shares. The Company shall deliver, or cause to be
delivered, a credit representing the Firm Shares to an account or accounts at
The Depository Trust Company, as designated by the Representatives for the
accounts of the Representatives and the several Underwriters at the First
Closing Date, against the irrevocable release of a wire transfer of immediately
available funds for the amount of the purchase price therefor. The Company shall
also deliver, or cause to be delivered a credit representing the Option Shares
the Underwriters have agreed to purchase at the First Closing Date (or the
Second Closing Date, as the case may be), to an account or accounts at The
Depository Trust Company as designated by the Representatives for the accounts
of the Representatives and the several Underwriters, against the irrevocable
release of a wire transfer of immediately available funds for the amount of the
purchase price therefor. Time shall be of the essence, and delivery at the


                                      10.
<PAGE>   11
time and place specified in this Agreement is a further condition to the
obligations of the Underwriters.

         (g) Delivery of Prospectus to the Underwriters. Not later than 12:00
noon on the second business day following the date the Shares are released by
the Underwriters for sale to the public, the Company shall deliver or cause to
be delivered copies of the Prospectus in such quantities and at such places as
the Representatives shall request.

         SECTION 3. COVENANTS OF THE COMPANY. The Company further covenants and
agrees with each Underwriter as follows:

         (a) Registration Statement Matters. The Company will (i) use its best
efforts to cause a registration statement on Form 8-A (the "Form 8-A
Registration Statement") as required by the Securities Exchange Act of 1934 (the
"Exchange Act") to become effective simultaneously with the Registration
Statement, (ii) use its best efforts to cause the Registration Statement to
become effective or, if the procedure in Rule 430A of the Securities Act is
followed, to prepare and timely file with the Commission under Rule 424(b) under
the Securities Act a Prospectus in a form approved by the Representatives
containing information previously omitted at the time of effectiveness of the
Registration Statement in reliance on Rule 430A of the Securities Act and (iii)
not file any amendment to the Registration Statement or supplement to the
Prospectus of which the Representatives shall not previously have been advised
and furnished with a copy or to which the Representatives shall have reasonably
objected in writing or which is not in compliance with the Securities Act. If
the Company elects to rely on Rule 462(b) under the Securities Act, the Company
shall file a Rule 462(b) Registration Statement with the Commission in
compliance with Rule 462(b) under the Securities Act prior to the time
confirmations are sent or given, as specified by Rule 462(b)(2) under the
Securities Act, and shall pay the applicable fees in accordance with Rule 111
under the Securities Act.

         (b) Securities Act Compliance. The Company will advise the
Representatives promptly (i) when the Registration Statement or any
post-effective amendment thereto shall have become effective, (ii) of receipt of
any comments from the Commission, (iii) of any request of the Commission for
amendment of the Registration Statement or for supplement to the Prospectus or
for any additional information and (iv) of the issuance by the Commission of any
stop order suspending the effectiveness of the Registration Statement or the use
of the Prospectus or of the institution of any proceedings for that purpose. The
Company will use its best efforts to prevent the issuance of any such stop order
preventing or suspending the use of the Prospectus and to obtain as soon as
possible the lifting thereof, if issued.

         (c) Blue Sky Compliance. The Company will cooperate with the
Representatives and counsel for the Underwriters in endeavoring to qualify the
Shares for sale under the securities laws of such jurisdictions (both national
and foreign) as the Representatives may reasonably have designated in writing
and will make such applications, file such documents, and furnish such
information as may be reasonably required for that purpose, provided the Company
shall not be required to qualify as a foreign corporation or to file a general
consent to service of process in any jurisdiction where it is not now so
qualified or required to file such a consent. The Company will, from time to
time, prepare and file such statements, reports and other documents, as are or
may be required to continue such qualifications in effect for so long a period
as the Representatives may reasonably request for distribution of the Shares.

         (d) Amendments and Supplements to the Prospectus and Other Securities
Act Matters. The Company will comply with the Securities Act and the Exchange
Act, and the rules


                                      11.
<PAGE>   12
and regulations of the Commission thereunder, so as to permit the completion of
the distribution of the Shares as contemplated in this Agreement and the
Prospectus. If during the period in which a prospectus is required by law to be
delivered by an Underwriter or dealer, any event shall occur as a result of
which, in the judgment of the Company or in the reasonable opinion of the
Representatives or counsel for the Underwriters, it becomes necessary to amend
or supplement the Prospectus in order to make the statements therein, in the
light of the circumstances existing at the time the Prospectus is delivered to a
purchaser, not misleading, or, if it is necessary at any time to amend or
supplement the Prospectus to comply with any law, the Company promptly will
prepare and file with the Commission, and furnish at its own expense to the
Underwriters and to dealers, an appropriate amendment to the Registration
Statement or supplement to the Prospectus so that the Prospectus as so amended
or supplemented will not, in the light of the circumstances when it is so
delivered, be misleading, or so that the Prospectus will comply with the law.

         (e) Copies of any Amendments and Supplements to the Prospectus. The
Company agrees to furnish the Representatives, without charge, during the period
beginning on the date hereof and ending on the later of the First Closing Date
or such date, as in the opinion of counsel for the Underwriters, the Prospectus
is no longer required by law to be delivered in connection with sales by an
Underwriter or dealer (the "Prospectus Delivery Period"), as many copies of the
Prospectus and any amendments and supplements thereto as the Representatives may
request.

         (f) Insurance. The Company shall (i) obtain Directors and Officers
liability insurance in the minimum amount of $10 million which shall apply to
the offering contemplated hereby and (ii) shall cause BancBoston Robertson
Stephens Inc. to be added as an additional insured to such policy in respect of
the offering contemplated hereby.

         (g) Notice of Subsequent Events. If at any time during the ninety (90)
day period after the Registration Statement becomes effective, any rumor,
publication or event relating to or affecting the Company shall occur as a
result of which in your opinion the market price of the Company Shares has been
or is likely to be materially affected (regardless of whether such rumor,
publication or event necessitates a supplement to or amendment of the
Prospectus), the Company will, after written notice from you advising the
Company to the effect set forth above, forthwith prepare, consult with you
concerning the substance of and disseminate a press release or other public
statement, reasonably satisfactory to you, responding to or commenting on such
rumor, publication or event.

         (h) Use of Proceeds. The Company shall apply the net proceeds from the
sale of the Shares sold by it in the manner described under the caption "Use of
Proceeds" in the Prospectus.

         (i) Transfer Agent. The Company shall engage and maintain, at its
expense, a registrar and transfer agent for the Company Shares.

         (j) Earnings Statement. As soon as practicable, the Company will make
generally available to its security holders and to the Representatives an
earnings statement (which need not be audited) covering the twelve-month period
ending [the date that is first quarter ending after one year following the
effective date] that satisfies the provisions of Section 11(a) of the Securities
Act.


                                      12.
<PAGE>   13
         (k) Periodic Reporting Obligations. During the Prospectus Delivery
Period the Company shall file, on a timely basis, with the Commission and the
Nasdaq National Market all reports and documents required to be filed under the
Exchange Act.

         (l) Agreement Not to Offer or Sell Additional Securities. The Company
will not, without the prior written consent of BancBoston Robertson Stephens
Inc., for a period of 180 days following the date of the Prospectus, offer, sell
or contract to sell, or otherwise dispose of or enter into any transaction which
is designed to, or could be expected to, result in the disposition (whether by
actual disposition or effective economic disposition due to cash settlement or
otherwise by the Company or any affiliate of the Company or any person in
privity with the Company or any affiliate of the Company) directly or
indirectly, or announce the offering of, any other Common Shares or any
securities convertible into, or exchangeable for, Common Shares; provided,
however, that the Company may (i) issue and sell Common Shares pursuant to any
director or employee stock option plan, stock ownership plan or dividend
reinvestment plan of the Company in effect at the date of the Prospectus and
described in the Prospectus so long as none of those shares may be transferred
on during the period of 180 days from the date that the Registration Statement
is declared effective (the "Lock-Up Period") and the Company shall enter stop
transfer instructions with its transfer agent and registrar against the transfer
of any such Common Shares and (ii) the Company may issue Common Shares issuable
upon the conversion of securities or the exercise of warrants outstanding at the
date of the Prospectus and described in the Prospectus.

         (m) Future Reports to the Representatives. During the period of five
years hereafter the Company will furnish to the Representatives (i) as soon as
practicable after the end of each fiscal year, copies of the Annual Report of
the Company containing the balance sheet of the Company as of the close of such
fiscal year and statements of income, stockholders' equity and cash flows for
the year then ended and the opinion thereon of the Company's independent public
or certified public accountants; (ii) as soon as practicable after the filing
thereof, copies of each proxy statement, Annual Report on Form 10-K, Quarterly
Report on Form 10-Q, Current Report on Form 8-K or other report filed by the
Company with the Commission, the National Association of Securities Dealers, LLC
or any securities exchange; and (iii) as soon as available, copies of any report
or communication of the Company mailed generally to holders of its capital
stock.

         SECTION 4. CONDITIONS OF THE OBLIGATIONS OF THE UNDERWRITERS. The
obligations of the several Underwriters to purchase and pay for the Shares as
provided herein on the First Closing Date and, with respect to the Option
Shares, the Second Closing Date, shall be subject to the accuracy of the
representations and warranties on the part of the Company set forth in Section 1
hereof as of the date hereof and as of the First Closing Date as though then
made and, with respect to the Option Shares, as of the Second Closing Date as
though then made, to the timely performance by the Company of its covenants and
other obligations hereunder, and to each of the following additional conditions:

         (a) Compliance with Registration Requirements; No Stop Order; No
Objection from the National Association of Securities Dealers, LLC. The
Registration Statement shall have become effective prior to the execution of
this Agreement, or at such later date as shall be consented to in writing by
you; and no stop order suspending the effectiveness thereof shall have been
issued and no proceedings for that purpose shall have been initiated or, to the
knowledge of the Company or any Underwriter, threatened by the Commission, and
any request of the Commission for additional information (to be included in the
Registration Statement or the Prospectus or otherwise) shall have been complied
with to the satisfaction of Underwriters'


                                      13.
<PAGE>   14
Counsel; and the National Association of Securities Dealers, LLC shall have
raised no objection to the fairness and reasonableness of the underwriting terms
and arrangements.

         (b) Corporate Proceedings. All corporate proceedings and other legal
matters in connection with this Agreement, the form of Registration Statement
and the Prospectus, and the registration, authorization, issue, sale and
delivery of the Shares, shall have been reasonably satisfactory to Underwriters'
Counsel, and such counsel shall have been furnished with such papers and
information as they may reasonably have requested to enable them to pass upon
the matters referred to in this Section.

         (c) No Material Adverse Change. Subsequent to the execution and
delivery of this Agreement and prior to the First Closing Date, or the Second
Closing Date, as the case may be, there shall not have been any Material Adverse
Change in the condition (financial or otherwise), earnings, operations, business
or prospects of the Company and its subsidiaries considered as one enterprise
from that set forth in the Registration Statement or Prospectus, which, in your
sole judgment, is material and adverse and that makes it, in your sole judgment,
impracticable or inadvisable to proceed with the public offering of the Shares
as contemplated by the Prospectus.

         (d) Opinion of Counsel for the Company. You shall have received on the
First Closing Date, or the Second Closing Date, as the case may be, an opinion
of Venture Law Group, counsel for the Company substantially in the form of
Exhibit B attached hereto, dated the First Closing Date, or the Second Closing
Date, addressed to the Underwriters and with reproduced copies or signed
counterparts thereof for each of the Underwriters.

             Counsel rendering the opinion contained in Exhibit B may rely as
to questions of law not involving the laws of the United States, the State of
New York or the State of California or general corporate laws of the State of
Delaware upon opinions of local counsel, and as to questions of fact upon
representations or certificates of officers of the Company, and of government
officials, in which case their opinion is to state that they are so relying and
that they have no knowledge of any material misstatement or inaccuracy in any
such opinion, representation or certificate. Copies of any opinion,
representation or certificate so relied upon shall be delivered to you, as
Representatives of the Underwriters, and to Underwriters' Counsel.

         (e) [Opinion of Patent Counsel for the Company]. You shall have
received on the First Closing Date, or the Second Closing Date, as the case may
be, an opinion of [NAME OF PATENT COUNSEL], patent counsel for the Company
substantially in the form of Exhibit C attached hereto.]

         (f) Opinion of Counsel for the Underwriters. You shall have received on
the First Closing Date or the Second Closing Date, as the case may be, an
opinion of Brobeck, Phleger & Harrison LLP, substantially in the form of Exhibit

matters.

Deloitte & Touche, LLP addressed to the Underwriters, dated the First Closing

independent certified public accountants with respect to the Company within the
meaning of the Act and the applicable published Rules and Regulations and based
upon the procedures described in such letter delivered to you concurrently with
the


                                      14.

execution of this Agreement (herein called the "Original Letter"), but carried
out to a date not more than four (4) business days prior to the First Closing
Date or the Second Closing Date, as the case may be, (i) confirming, to the
extent true, that the statements and conclusions set forth in the Original
Letter are accurate as of the First Closing Date or the Second Closing Date, as
the case may be, and (ii) setting forth any revisions and additions to the
statements and conclusions set forth in the Original Letter which are necessary
to reflect any changes in the facts described in the Original Letter since the
date of such letter, or to reflect the availability of more recent financial
statements, data or information. The letter shall not disclose any change in the
condition (financial or otherwise), earnings, operations, business or business
prospects of the Company and its subsidiaries considered as one enterprise from
that set forth in the Registration Statement or Prospectus, which, in your sole
judgment, is material and adverse and that makes it, in your sole judgment,
impracticable or inadvisable to proceed with the public offering of the Shares
as contemplated by the Prospectus. The Original Letter from Deloitte & Touche,
LLP shall be addressed to or for the use of the Underwriters in form and
substance satisfactory to the Underwriters and shall (i) represent, to the
extent true, that they are independent certified public accountants with respect
to the Company within the meaning of the Act and the applicable published Rules
and Regulations, (ii) set forth their opinion with respect to their examination

flows for the twelve (12) months ended December 31, 1998, (iii) state that
Deloitte & Touche, LLP has performed the procedures set out in Statement on
Auditing Standards No. 71 ("SAS 71") for a review of interim financial
information and providing the report of Deloitte & Touche, LLP as described in
SAS 71 on the financial statements for [each of the quarters in the ____]
quarter period ended [March 31], 1999 (the "Quarterly Financial Statements"),
(iv) state that in the course of such review, nothing came to their attention
that leads them to believe that any material modifications need to be made to
any of the Quarterly Financial Statements in order for them to be in compliance
with generally accepted accounting principles consistently applied across the
periods presented, (v) state that Deloitte & Touche, LLP has performed the
procedures set out in Statement on Auditing Standards No. 86 with respect to
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" contained in the Prospectus and (vi) address other matters agreed
upon by Deloitte & Touche, LLP and you. In addition, you shall have received
from Deloitte & Touche, LLP a letter addressed to the Company and made available
to you for the use of the Underwriters stating that their review of the
Company's system of internal accounting controls, to the extent they deemed
necessary in establishing the scope of their examination of the Company's
consolidated financial statements as of December 31, 1998, did not disclose any
weaknesses in internal controls that they considered to be material weaknesses.

         (h) Officers' Certificate. You shall have received on the First Closing
Date and the Second Closing Date, as the case may be, a certificate of the
Company, dated the First Closing Date or the Second Closing Date, as the case
may be, signed by the Chief Executive Officer and Chief Financial Officer of the
Company, to the effect that, and you shall be satisfied that:

         (i) The representations and warranties of the Company in this Agreement
         are true and correct, as if made on and as of the First Closing Date or

         (ii) No stop order suspending the effectiveness of the Registration
         Statement has been issued and no proceedings for that purpose have been
         instituted or are pending or threatened under the Act;

         (iii) When the Registration Statement became effective and at all times
         subsequent thereto up to the delivery of such certificate, the
         Registration Statement and the Prospectus, and any amendments or
         supplements thereto contained all material information required to be
         included therein by the Securities Act and in all material respects
         conformed to the requirements of the Securities Act, the Registration
         Statement and the Prospectus, and any amendments or supplements
         thereto, did not and does not include any untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading;
         and, since the effective date of the Registration Statement, there has
         occurred no event required to be set forth in an amended or
         supplemented Prospectus which has not been so set forth; and

         and its subsidiaries considered as one enterprise, (b) any transaction
         that is material to the Company and its subsidiaries considered as one
         enterprise, except transactions entered into in the ordinary course of
         business, (c) any obligation, direct or contingent, that is material to
         the Company and its subsidiaries considered as one enterprise, incurred
         by the Company or its subsidiaries, except obligations incurred in the
         ordinary course of business, (d) any change in the capital stock or
         outstanding indebtedness of the Company or any of its subsidiaries that

         enterprise, (e) any dividend or distribution of any kind declared, paid
         or made on the capital stock of the Company or any of its subsidiaries,
         or (f) any loss or damage (whether or not insured) to the property of
         the Company or any of its subsidiaries which has been sustained or will
         have been sustained which has a material adverse effect on the
         condition (financial or otherwise), earnings, operations, business or
         prospects of the Company and its subsidiaries considered as one
         enterprise.

         (i) Lock-up Agreement from Certain Stockholders of the Company. The

<PAGE>   17
representations and warranties, or the satisfaction of any of the conditions or
agreements, herein contained.

             If any condition specified in this Section 4 is not satisfied when
and as required to be satisfied, this Agreement may be terminated by the
Representatives by notice to the Company at any time on or prior to the First
Closing Date and, with respect to the Option Shares, at any time prior to the

         The Company shall indemnify and hold harmless each Underwriter, its
officers and employees, and each person, if any, who controls any Underwriter
within the meaning of the Securities Act and the Exchange Act against any loss,
claim, damage, liability or expense, as incurred, to which such Underwriter or

Exchange Act or other federal or state statutory law or regulation, or at common
law or otherwise (including in settlement of any litigation, if such settlement

representations and warranties of the Company contained herein; or (iv) in whole
or in part upon any failure of the Company to perform its obligations hereunder

referred to in any loss, claim, damage, liability or action arising out of or
based upon any matter covered by clause (i), (ii), (iii) or (iv) above, provided
that the Company shall not be liable under this clause (v) to the extent that a
court of competent jurisdiction shall have determined by a final judgment that
such loss, claim, damage, liability or action resulted directly from any such
acts or failures to act undertaken or omitted to be taken by such Underwriter
through its bad faith or willful misconduct; and to reimburse each Underwriter
and each such controlling person for any and all expenses (including the fees
and disbursements of counsel chosen by BancBoston Robertson Stephens Inc.) as
such expenses are reasonably incurred by such Underwriter or such controlling
person in connection with investigating, defending, settling, compromising or
paying any such loss, claim, damage, liability, expense or action; provided,
however, that the foregoing indemnity agreement shall not apply to any loss,
claim, damage, liability or expense to the extent, but only to the extent,
arising out of or based upon any untrue statement or alleged untrue statement or
omission or alleged omission made in reliance upon and in conformity with
written information furnished to the Company by the Representatives expressly
for use in the Registration Statement, any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto); and provided, further, that
with respect to any preliminary prospectus, the foregoing indemnity agreement

amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Underwriter
to such person, if required by law so

to have been delivered, at or prior to the written confirmation of the sale of
the Shares to such person, and if the Prospectus (as so amended or supplemented)
would have cured the defect giving rise to such loss, claim, damage, liability
or expense. The indemnity agreement set forth in this Section 7(a) shall be in
addition to any liabilities that the Company may otherwise have.

         (b) Indemnification of the Company, its Directors and Officers. Each
Underwriter agrees, severally and not jointly, to indemnify and hold harmless
the Company, each of its directors, each of its officers who signed the
Registration Statement and each person, if any, who controls the Company within
the meaning of the Securities Act or the Exchange Act, against any loss, claim,
damage, liability or expense, as incurred, to which the Company, or any such
director, officer or controlling person may become subject, under the Securities
Act, the Exchange Act, or other federal or state statutory law or regulation, or
at common law or otherwise (including in settlement of any litigation, if such
settlement is effected with the written consent of such Underwriter), insofar as
such loss, claim, damage, liability or expense (or actions in respect thereof as
contemplated below) arises out of or is based upon any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or arises out of or is based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in the Registration Statement, any preliminary
prospectus, the Prospectus (or any amendment or supplement thereto), in reliance
upon and in conformity with written information furnished to the Company by the
Representatives expressly for use therein; and to reimburse the Company, or any
such director, officer or controlling person for any legal and other expense
reasonably incurred by the Company, or any such director, officer or controlling
person in connection with investigating, defending, settling, compromising or
paying any such loss, claim, damage, liability, expense or action. The indemnity
agreement set forth in this Section 7(b) shall be in addition to any liabilities
that each Underwriter may otherwise have.

         (c) Information Provided by the Underwriters. The Company hereby
acknowledges that the only information that the Underwriters have furnished to
the Company expressly for use in the Registration Statement, any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto) are the
statements set forth in the table in the first paragraph, the second paragraph
and the ninth paragraph under the caption "Underwriting" in the Prospectus; and
the Underwriters confirm that such statements are correct.

         (d) Notifications and Other Indemnification Procedures. Promptly after
receipt by an indemnified party under this Section 7 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 7, notify
the indemnifying party in writing of the commencement thereof, but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party for contribution or otherwise than under
the indemnity agreement contained in this Section 7 or to the extent it is not
prejudiced as a proximate result of such failure. In case any such action is
brought against any indemnified party and such indemnified party seeks or
intends to seek indemnity from an indemnifying party, the indemnifying party
will be entitled to participate in, and, to the extent that it shall elect,
jointly with all other indemnifying parties similarly notified, by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party; provided, however, if the
defendants in any such action include both the indemnified party and the
indemnifying party and the


                                      19.
<PAGE>   20
indemnified party shall have reasonably concluded that a conflict may arise
between the positions of the indemnifying party and the indemnified party in
conducting the defense of any such action or that there may be legal defenses
available to it and/or other indemnified parties which are different from or
additional to those available to the indemnifying party, the indemnified party
or parties shall have the right to select separate counsel to assume such legal
defenses and to otherwise participate in the defense of such action on behalf of
such indemnified party or parties. Upon receipt of notice from the indemnifying
party to such indemnified party of such indemnifying party's election so to
assume the defense of such action and approval by the indemnified party of
counsel, the indemnifying party will not be liable to such indemnified party
under this Section 7 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (together with local counsel), approved by the indemnifying
party (BancBoston Robertson Stephens Inc. in the case of Section 7(b) and
Section 8), representing the indemnified parties who are parties to such
action), (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of commencement of the action, or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party, in each of which cases the fees
and expenses of counsel shall be at the expense of the indemnifying party.

         (e) Settlements. The indemnifying party under this Section 7 shall not
be liable for any settlement of any proceeding effected without its written
consent, which consent shall not be unreasonably withheld, but if settled with
such consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party against any loss, claim, damage,
liability or expense by reason of such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel as contemplated by Section 7(d) hereof, the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 30 days
after receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement, compromise or consent to the entry of judgment in any pending or
threatened action, suit or proceeding in respect of which any indemnified party
is or could have been a party and indemnity was or could have been sought
hereunder by such indemnified party, unless such settlement, compromise or
consent includes (i) an unconditional release of such indemnified party from all
liability on claims that are the subject matter of such action, suit or
proceeding and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

         (f) Contribution. If the indemnification provided for in this Section 7
is unavailable to or insufficient to hold harmless an indemnified party under
Section 7(a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) then each
indemnifying party shall contribute to the aggregate amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Underwriters
on the other from the offering of the Shares. If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law then each indemnifying party shall contribute to such amount paid or payable
by such indemnified party in such proportion as is appropriate to reflect not
only such


                                      20.
<PAGE>   21
relative benefits but also the relative fault of the Company on the one hand and
the Underwriters on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities, (or actions or
proceedings in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriter on the other shall be deemed to be in the same proportion as
the total net proceeds from the offering (before deducting expenses) received by
the Company bears to the total underwriting discounts and commissions received
by the Underwriters, in each case as set forth in the table on the cover page of
the Prospectus. The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or the Underwriters on the
other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

             The Company and Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 7(f) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 7(f). The amount paid
or payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to above in
this Section 7(f) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (f), (i) no Underwriter shall be required to contribute any amount in
excess of the underwriting discounts and commissions applicable to the Shares
purchased by such Underwriter and (ii) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this Section 7(f)
to contribute are several in proportion to their respective underwriting
obligations and not joint.

         (g) Timing of Any Payments of Indemnification. Any losses, claims,
damages, liabilities or expenses for which an indemnified party is entitled to
indemnification or contribution under this Section 7 shall be paid by the
indemnifying party to the indemnified party as such losses, claims, damages,
liabilities or expenses are incurred, but in all cases, no later than thirty
(30) days of invoice to the indemnifying party.

         (h) Survival. The indemnity and contribution agreements contained in
this Section 7 and the representation and warranties of the Company set forth in
this Agreement shall remain operative and in full force and effect, regardless
of (i) any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter, the Company, its directors or officers or any
persons controlling the Company, (ii) acceptance of any Shares and payment
therefor hereunder, and (iii) any termination of this Agreement. A successor to
any Underwriter, or to the Company, its directors or officers, or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 7.

         (i) Acknowledgements of Parties. The parties to this Agreement hereby
acknowledge that they are sophisticated business persons who were represented by
counsel during the negotiations regarding the provisions hereof including,
without limitation, the provisions of this Section 7, and are fully informed
regarding said provisions. They further acknowledge that the provisions of this
Section 7 fairly allocate the risks in light of the ability of


                                      21.
<PAGE>   22
the parties to investigate the Company and its business in order to assure that
adequate disclosure is made in the Registration Statement and Prospectus as
required by the Securities Act and the Exchange Act.

         SECTION 8. DEFAULT OF ONE OR MORE OF THE SEVERAL UNDERWRITERS. If, on
the First Closing Date or the Second Closing Date, as the case may be, any one
or more of the several Underwriters shall fail or refuse to purchase Shares that
it or they have agreed to purchase hereunder on such date, and the aggregate
number of Common Shares which such defaulting Underwriter or Underwriters agreed
but failed or refused to purchase does not exceed 10% of the aggregate number of
the Shares to be purchased on such date, the other Underwriters shall be
obligated, severally, in the proportions that the number of Firm Common Shares
set forth opposite their respective names on Schedule A bears to the aggregate
number of Firm Shares set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as may be specified by the
Representatives with the consent of the non-defaulting Underwriters, to purchase
the Shares which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase on such date. If, on the First Closing Date or the Second
Closing Date, as the case may be, any one or more of the Underwriters shall fail
or refuse to purchase Shares and the aggregate number of Shares with respect to
which such default occurs exceeds 10% of the aggregate number of Shares to be
purchased on such date, and arrangements satisfactory to the Representatives and
the Company for the purchase of such Shares are not made within 48 hours after
such default, this Agreement shall terminate without liability of any party to
any other party except that the provisions of Section 4, and Section 7 shall at
all times be effective and shall survive such termination. In any such case
either the Representatives or the Company shall have the right to postpone the
First Closing Date or the Second Closing Date, as the case may be, but in no
event for longer than seven days in order that the required changes, if any, to
the Registration Statement and the Prospectus or any other documents or
arrangements may be effected.

             As used in this Agreement, the term "Underwriter" shall be deemed
to include any person substituted for a defaulting Underwriter under this
Section 8. Any action taken under this Section 8 shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

         SECTION 9. TERMINATION OF THIS AGREEMENT. Prior to the First Closing
Date, this Agreement may be terminated by the Representatives by notice given to
the Company if at any time (i) trading or quotation in any of the Company's
securities shall have been suspended or limited by the Commission or by the
Nasdaq Stock Market, or trading in securities generally on either the Nasdaq
Stock Market or the New York Stock Exchange shall have been suspended or
limited, or minimum or maximum prices shall have been generally established on
any of such stock exchanges by the Commission or the National Association of
Securities Dealers, LLC; (ii) a general banking moratorium shall have been
declared by any of federal, New York or California authorities; (iii) there
shall have occurred any outbreak or escalation of national or international
hostilities or any crisis or calamity, or any change in the United States or
international financial markets, or any substantial change or development
involving a prospective change in United States' or international political,
financial or economic conditions, as in the judgment of the Representatives is
material and adverse and makes it impracticable or inadvisable to market the
Common Shares in the manner and on the terms described in the Prospectus or to
enforce contracts for the sale of securities; (iv) in the judgment of the
Representatives there shall have occurred any Material Adverse Change; or (v)
the Company shall have sustained a loss by strike, fire, flood, earthquake,
accident or other calamity of such character as in the judgment of the
Representatives may interfere materially with the conduct of


                                      22.
<PAGE>   23
the business and operations of the Company regardless of whether or not such
loss shall have been insured. Any termination pursuant to this Section 9 shall
be without liability on the part of (a) the Company to any Underwriter, except
that the Company shall be obligated to reimburse the expenses of the
Representatives and the Underwriters pursuant to Sections 5 and 6 hereof, (b)
any Underwriter to the Company, or (c) of any party hereto to any other party
except that the provisions of Section 7 shall at all times be effective and
shall survive such termination.

         SECTION 10. REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY. The
respective indemnities, agreements, representations, warranties and other
statements of the Company, of its officers and of the several Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter
or the Company or any of its or their partners, officers or directors or any
controlling person, as the case may be, and will survive delivery of and payment
for the Shares sold hereunder and any termination of this Agreement.

         SECTION 11. NOTICES. All communications hereunder shall be in writing

accordance with the internal laws of the state of California applicable to

         (b) Consent to Jurisdiction. Any legal suit, action or proceeding
arising out of or based upon this Agreement or the transactions contemplated
hereby ("Related Proceedings") may be instituted in the federal courts of the
United States of America located in the City and County of San Francisco or the
courts of the State of California in each case located in the City and County of
San Francisco (collectively, the "Specified Courts"), and each party irrevocably
submits to the exclusive jurisdiction (except for proceedings instituted in
regard to the enforcement of a judgment of any such court (a "Related
Judgment"), as to which such jurisdiction is non-exclusive) of such courts in
any such suit, action or proceeding. Service of any process, summons, notice or
document by mail to such party's address set forth above shall be effective
service of process for any suit, action or other proceeding brought in any such
court. The parties irrevocably and unconditionally waive any objection to the
laying of venue of any suit, action or other proceeding in the Specified Courts
and irrevocably and unconditionally waive and agree not to plead or claim in any
such court that any such suit, action or other proceeding brought in any such
court has been brought in an inconvenient forum. Each party not located in the
United States irrevocably appoints CT Corporation System, which currently
maintains a San Francisco office at 49 Stevenson Street, San Francisco,
California 94105, United States of America, as its agent to receive service of
process or other legal summons for purposes of any such suit, action or
proceeding that may be instituted in any state or federal court in the City and
County of San Francisco.

         (c) Waiver of Immunity. With respect to any Related Proceeding, each
party irrevocably waives, to the fullest extent permitted by applicable law, all
immunity (whether on the basis of sovereignty or otherwise) from jurisdiction,
service of process, attachment (both before and after judgment) and execution to
which it might otherwise be entitled in the Specified Courts, and with respect
to any Related Judgment, each party waives any such immunity in the Specified
Courts or any other court of competent jurisdiction, and will not raise or claim
or cause to be pleaded any such immunity at or in respect of any such Related
Proceeding or Related Judgment, including, without limitation, any immunity
pursuant to the United States Foreign Sovereign Immunities Act of 1976, as
amended.

with respect to the subject matter hereof. This Agreement may be executed in two

effect as if the signatures thereto and hereto were upon the same instrument.

filed as an exhibit to the Registration Statement, which are not described or
referred to therein or filed as required;

(xv) The performance of this Agreement and the consummation of the transactions
herein contemplated (other than performance of the Company's indemnification
obligations hereunder, concerning which no opinion need be expressed) will not
(a) result in any violation of the Company's charter or bylaws or (b) to such
counsel's knowledge, result in a material breach or violation of any of the
terms and provisions of, or constitute a default under, any bond, debenture,
note or other evidence of indebtedness, or any lease, contract, indenture,
mortgage, deed of trust, loan agreement, joint venture or other agreement or
instrument known to such counsel to which the Company is a party or by which its
properties are bound, or any applicable statute, rule or regulation known to

(xvi) No consent, approval, authorization or order of or qualification with any
court, government or governmental agency or body having jurisdiction over the
Company or any of its subsidiaries, or over any of their properties or
operations is necessary in connection with the consummation by the Company of

subsidiaries is presently (a) in material violation of its respective charter or
bylaws, or (b) in material breach of any applicable statute, rule or regulation
known to such counsel or, to such counsel's knowledge, any order, writ or decree

(xix) To such counsel's knowledge, except as set forth in the Registration
Statement and Prospectus, no holders of Company Shares or other securities of
the Company have registration rights with respect to securities of the Company
and, except as set forth in the Registration Statement and Prospectus, all
holders of securities of the Company having rights known to such counsel to
registration of such shares of Company Shares or other securities, because of
the filing of the Registration Statement by the Company have, with respect to
the offering contemplated thereby, waived such rights or such rights have

such rights.

trademarks, trade names, patent rights, copyrights, licenses, approvals, trade
secrets and other similar rights (collectively, "Intellectual Property Rights")
reasonably necessary to conduct their business as now conducted; and the
expected expiration of any such Intellectual Property Rights would not result in
a Material Adverse Effect. The Company has not received any notice of
infringement or conflict with asserted Intellectual Property Rights of others,
which infringement or conflict, if the subject of an unfavorable decision, would
result in a Material Adverse Effect. To such counsel's knowledge, the Company's
discoveries, inventions, products, or processes referred to in the Registration
Statement or Prospectus do not infringe or conflict with any right or patent
which is the subject of a patent application known to the Company.

         In addition, such counsel shall state that such counsel has
participated in conferences with officials and other representatives of the
Company, the Representatives, Underwriters' Counsel and the independent
certified public accountants of the Company, at which such conferences the
contents of the Registration Statement and Prospectus and related matters were
discussed, and although they have not verified the accuracy or completeness of
the statements contained in the Registration Statement or the Prospectus,
nothing has come to the attention of such counsel which leads them to believe
that, at the time the Registration Statement became effective and at all times
subsequent thereto up to and on the First Closing Date or Second Closing Date,
as the case may be, the Registration Statement and any amendment or supplement
thereto (other than the financial statements including supporting schedules and
other financial and statistical information derived therefrom, as to which such
counsel need express no comment) contained any untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, or at the First Closing
Date or the Second Closing Date, as the case may be, the Registration Statement,
the Prospectus and any amendment or supplement thereto (except as aforesaid)
contained any untrue statement of a material fact or omitted to state a material
fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

                                    EXHIBIT C

                     MATTERS TO BE COVERED IN THE OPINION OF
                         PATENT COUNSEL FOR THE COMPANY

             Such counsel are familiar with the technology used by the Company
in its business and the manner of its use thereof and have read the Registration
Statement and the Prospectus, including particularly the portions of the
Registration Statement and the Prospectus referring to patents, trade secrets,
trademarks, service marks or other proprietary information or materials and:

         (i) The Company is listed in the records of the United States Patent
         and Trademark Office as the holder of record of the patents listed on a
         schedule to such opinion (the "Patents") and each of the applications
         listed on a schedule to such opinion (the "Applications"). To the
         knowledge of such counsel, there are no claims of third parties to any
         ownership interest or lien with respect to any of the Patents or
         Applications. Such counsel is not aware of any material defect in form
         in the preparation or filing of the Applications on behalf of the
         Company. To the knowledge of such counsel, the Applications are being
         pursued by the Company. To the knowledge of such counsel, the Company
         owns as its sole property the Patents and pending Applications;

         (ii) The Company is listed in the records of the appropriate foreign
         offices as the sole holder of record of the foreign patents listed on a
         schedule to such opinion (the "Foreign Patents") and each of the
         applications listed on a schedule to such opinion (the "Foreign
         Applications"). Such counsel knows of no claims of third parties to any
         ownership interest or lien with respect to the Foreign Patents or
         Foreign Applications. Such counsel is not aware of any material defect
         of form in the preparation or filing of the Foreign Applications on
         behalf of the Company. To the knowledge of such counsel, the Foreign
         Applications are being pursued by the Company. To the knowledge of such
         counsel, the Company owns as its sole property the Foreign Patents and
         pending Foreign Applications;

         (iii) Such counsel knows of no reason why the Patents or Foreign
         Patents are not valid as issued. Such counsel has no knowledge of any
         reason why any patent to be issued as a result of any Application or
         Foreign Application would not be valid or would not afford the Company
         useful patent protection with respect thereto;

         (iv) As to the statements under the captions "Risk Factors --
         Dependence on Patents and Proprietary Rights" and "Business -- Patents
         and Proprietary Rights," nothing has come to the attention of such
         counsel which caused them to believe that the above-mentioned sections
         of the Registration Statement, at the time the Registration Statement
         became effective and at all times subsequent thereto up to and on the
         Closing Date and on any later date on which Option Stock are to be
         purchased the Registration Statement and any amendment or supplement
         thereto made available and reviewed by such counsel contained any
         untrue statement of a material fact or omitted to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, or at the Closing Date or any later date on
         which the Option Stock are to be purchased, as the case may be, the
         above-mentioned sections of the Registration Statement, Prospectus and
         any amendment or supplement thereto made available and reviewed by such
         counsel contained any untrue statement of a material fact or omitted to
         state a material fact required to be stated therein or necessary to
         make


                                      C-1
<PAGE>   34
         the statements therein, in light of the circumstances under which they
         were made, not misleading; and

         (v) Such counsel knows of no material action, suit, claim or proceeding
         relating to patents, patent rights or licenses, trademarks or trademark
         rights, copyrights, collaborative research, licenses or royalty
         arrangements or agreements or trade secrets, know-how or proprietary
         techniques, including processes and substances, owned by or affecting
         the business or operations of the Company which are pending or
         threatened against the Company or any of its officers or directors.

nothing has come to the attention of such counsel which leads them to believe
that, at the time the Registration Statement became effective and at all times
subsequent thereto up to and on the First Closing Date or Second Closing Date,
as the case may be, the Registration Statement and any amendment or supplement
thereto (other than the financial statements including supporting schedules and

                                  CAPITAL STOCK

         The relative rights, preferences, privileges and restrictions granted

         Section 1. Dividends. The holders of Series A Preferred Stock shall be
entitled to receive cumulative dividends, prior to the payment of any dividends
on the Common Stock, at the rate of $0.035797 per annum per share of Series A
Preferred Stock then held by them, the holders of Series B Preferred Stock shall

<PAGE>   4

the payment of any dividends on the Common Stock, at the rate of $0.1374 per

prior to the payment of any dividends on the Common Stock, at the rate of
$0.2778 per annum per share of Series C Preferred Stock then held by them, and

Stock, at the rate of $0.321 per annum per share of Series D Preferred Stock
then held by them, out of any funds legally available therefor, when and as
declared by the Board of Directors or upon the event of any liquidation,
dissolution or winding up of the Corporation. No dividends shall be paid to
holders of Common Stock unless all accrued dividends on the Series A Preferred
Stock have been declared and paid and all declared dividends on the Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock have been
paid, and unless at the same time dividends equal to the dividends paid per
share of Common Stock are declared and paid to holders of Preferred Stock based
on the number of shares of Common Stock into which each share of Preferred Stock
is then convertible, as adjusted from time to time pursuant to Section 4 hereof.

         Dividends, if paid or declared and set apart for payment, must be paid
or declared and set apart for payment in full on the Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock
contemporaneously, or, if less than full dividends are paid or declared and set
apart for payment on the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock, the same percentage of
dividends shall be paid or declared and set apart for payment on each such
series of Preferred Stock, based on the aggregate dividend preference of each
such series.

         Section 2.   Liquidation Preference.

                  (a) (i) In the event of any liquidation, dissolution or
winding up of the Corporation, either voluntary or involuntary, the holders of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock shall be entitled to receive, prior and in preference
to any distribution of any of the assets or surplus funds of the Corporation to
the holders of Common Stock by reason of their ownership thereof, an amount per
share equal to (as such amount shall be adjusted to reflect subdivisions and
combinations of shares and stock dividends), (i) with respect to each
outstanding share of Series A Preferred Stock, $0.59662 (the "Original Series A
Liquidation Price"), together with all accrued but unpaid dividends with respect
to each such share (the "Series A Liquidation Amount"), (ii) with respect to
each outstanding share of Series B Preferred Stock, $2.29 (the "Original Series
B Liquidation Price"), together with all declared but unpaid dividends with
respect to each such share (the "Series B Liquidation Amount"), (iii) with
respect to each outstanding share of Series C Preferred Stock, $4.63 (the
"Original Series C Liquidation Price"), together with all declared but unpaid
dividends with respect to each such share (the "Series C Liquidation Amount"),
and (iv) with respect to each outstanding share of Series D Preferred Stock,
$5.35 (the "Original Series D Liquidation Price"), together with all declared
but unpaid dividends with respect to each such share (the "Series D Liquidation
Amount"). If the assets and funds legally available for distribution among the
holders of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock shall be insufficient to permit the
payment to such
<PAGE>   5

holders of the full preferential amount, then such assets and funds shall be
distributed ratably among the holders of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock in
proportion to the total preferential liquidation amount which each such holder
is entitled to receive.

                      (ii) Upon the completion of the distribution required by
Section 2(a)(i) above, the remaining assets of the Corporation available for
distribution to shareholders shall be distributed between the holders of the
Series C Preferred Stock and the Common Stock pro rata based on the number of
shares of Common Stock held by each (assuming conversion of all such shares of
Series C Preferred Stock) until the holders of Series C Preferred Stock shall
have received an aggregate of $6.945 per share of Series C Preferred Stock held
(including amounts paid pursuant to Section 2(a)(i) above) and; thereafter, if
assets remain in the Corporation, the holders of the Common Stock of the
Corporation shall receive all of the remaining assets of the Corporation pro
rata based on the number of shares of Common Stock held by each.

                  (b) (i) For purposes of this Section 2, a liquidation,
dissolution or winding up of the Corporation shall be deemed to be occasioned
by, and to include, (A) the Corporation's sale of all or substantially all of
its assets or (B) the consolidation or merger of the Corporation with or into
any other corporation or corporations or the effecting by the Corporation of a
transaction or series of related transactions after the Original Issue Date, as
hereinafter defined, in which the shareholders of record of the Company
immediately prior to such transaction or series of related transactions will
hold (by virtue of the voting securities issued as consideration for such
transaction or series of related transactions) less than 50% of the voting
securities of the surviving entity (or parent, if any) immediately after such
transaction or series of related transactions.

                      (ii) In any of such events, if the consideration received
by the Corporation is other than cash or indebtedness its value will be deemed
to be its fair market value. In the case of securities, fair market value shall
be determined as follows:

                           (A) Securities not subject to investment or other
similar restrictions on free marketability:

                                    (I) If traded on a securities exchange, the
value shall be deemed to be the average of the closing sale prices of the
securities on such exchange over the 30-day period ending three (3) days prior
to the closing;

                                    (II) If actively traded over-the-counter,
the value shall be deemed to be the average of the closing sale prices over the
30-day period ending three (3) days prior to the closing; and

                                    (III) If there is no active public market,
the value shall be the fair market value thereof, as mutually determined by the
Corporation and the holders of not less than a majority of the then-outstanding
shares of Preferred Stock, based on the number of shares of Common Stock into
which each share of Preferred Stock is convertible, as adjusted from time to
time pursuant to Section 4 hereof.
<PAGE>   6

                           (B) The method of valuation of securities subject to
investment letter or other restrictions on free marketability shall be to make
an appropriate discount from the market value determined as above in (A) (I),
(II) or (III) to reflect the approximate fair market value thereof, as mutually
determined by the Corporation and the holders of a majority of the
then-outstanding shares of Preferred Stock based on the number of shares of
Common Stock into which each share of Preferred Stock is convertible, as
adjusted from time to time pursuant to Section 4 hereof.

                           (C) If such holders and the Corporation are unable to
agree as to matters for which their agreement is called for in this Section
2(b)(ii), the value of such consideration shall be determined by two investment
bankers owning seats on the New York Stock Exchange who have no past, present or
contemplated relationship with the Corporation or the holders of the
then-outstanding shares of Preferred Stock, one of whom shall be selected by the
Corporation's Board of Directors and the other by the holders of a majority of
the then-outstanding shares of Preferred Stock, voting together as a class,
based on the number of shares of Common Stock into which each share of Preferred
Stock is convertible, as adjusted from time to time pursuant to Section 4
hereof. Any such determination of value shall be final and binding on the
Corporation and such holders.

         Section 3.   Voting Rights.

                  (a) General. Each holder of shares of Common Stock issued and
outstanding shall have one vote for each such share and each holder of shares of
Preferred Stock issued and outstanding shall have the number of votes equal to
the number of shares of Common Stock into which such shares of Preferred Stock
are convertible at the record date for determination of the shareholders
entitled to vote on such matters or, if no such record date is established, at
the date such vote is taken or any written consent of shareholders is solicited,
such votes to be counted together with all other shares of stock of the
Corporation having general voting power and not separately as a class.
Fractional votes by the holders of Preferred Stock shall not, however, be
permitted and any fractional voting rights shall (after aggregating all shares
into which shares of Preferred Stock held by each holder could be converted) be
rounded to the nearest whole number. Each holder of shares of Preferred Stock
shall be entitled to receive notice, together with the holders of each share of
Common Stock, of all shareholder meetings even if only the holders of Common
Stock are entitled to vote on the issues addressed at such meeting.

                  (b) Board of Directors. The authorized number of directors is
set at eight (8) and may be increased or decreased only by an amendment to these
Articles of Incorporation. At all elections of members of the Corporation's
Board of Directors, each holder of shares of the Corporation's stock shall be
entitled to as many votes as shall equal the number of votes which such holder
would be entitled to cast for the election of directors with respect to such
holder's shares of stock multiplied by the number of directors to be elected by
such holder, and such holder may cast all of such votes for a single director or
may distribute them among the number to be voted for, or for any two (2) or more
of them as such holder may see fit.

         Section 4.   Conversion.  The holders of Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

                  (a)      Right to Convert.

                           (i) Optional Conversion. Each share of each series of
Preferred Stock shall be convertible at the option of the holder thereof at any
time after the date of issuance of such share, at the office of the Corporation
or any transfer agent for the Preferred Stock, into such number of fully paid
and nonassessable shares of Common Stock as is determined by dividing the
Original Liquidation Price for such series of Preferred Stock by the Conversion
Price at the time in effect for such series of Preferred Stock. The initial
Conversion Price for shares of Series A Preferred Stock shall be the Original
Series A Liquidation Price; the initial Conversion Price for shares of Series B
Preferred Stock shall be the Original Series B Liquidation Price; the initial
Conversion Price for shares of Series C Preferred Stock shall be the Original
Series C Liquidation Price; and the initial Conversion Price for shares of
Series D Preferred Stock shall be the Original Series D Liquidation Price;
provided, however, that the Conversion Price for each such series of Preferred
Stock shall be subject to adjustment as set forth below.

                           (ii) Automatic Conversion. Each share of each series
of Preferred Stock shall automatically be converted into shares of Common Stock
at the then-effective Conversion Price for such series of Preferred Stock upon
(a) the closing of an underwritten public offering pursuant to an effective
registration statement on Form S-1 (or a successor form) under the Securities
Act of 1933, as amended, covering the offer and sale of Common Stock for the
account of the Corporation to the public at an aggregate offering price of not
less than Twelve Million Dollars ($12,000,000) and at a public offering price
per share (prior to underwriter commissions and expenses) that is not less than
$7.00 (as adjusted to reflect subdivisions and combinations of shares of Common
Stock and stock dividends paid in shares of Common) or (b) the date specified by
vote or written consent or agreement of: (i) the holders of at least two-thirds
(66 2/3%) of the then outstanding shares of Preferred Stock, voting together as
a single class on an as-converted to Common Stock basis, and (ii) the holders of
at least a majority of the then outstanding shares of Series C Preferred Stock
and Series D Preferred Stock, voting together as a single class on an
as-converted to Common Stock basis. In the event of such a public offering, the
person(s) entitled to receive the Common Stock issuable upon conversion of
Preferred Stock shall not be deemed to have converted such Preferred Stock until
immediately prior to the closing of such sale of Common Stock, at which time
each series of Preferred Stock shall be converted automatically without any
further action by the holders of such shares and whether or not the certificates
representing such shares are surrendered to the Corporation or its transfer
agent; provided, however, that the Corporation shall not be obligated to issue
certificates evidencing the shares of Common Stock issuable upon such conversion
unless certificates evidencing such shares of Preferred Stock being converted
are either delivered to the Corporation or its transfer agent, as hereinafter
provided, or the holder notifies the Corporation or any transfer agent, as
hereinafter provided, that such certificates have been lost, stolen or destroyed
and executes an agreement satisfactory to the Corporation to indemnify the
Corporation from any loss incurred by it in connection therewith. Upon the
automatic conversion of the Preferred
<PAGE>   8

Stock, the holders of the Preferred Stock shall surrender the certificates
representing such shares at the office of the Corporation or of any transfer
agent for the Preferred Stock. Thereupon, there shall be issued and delivered to
such holder, promptly at such office and in such holder's name as shown on such
surrendered certificate or certificates, a certificate or certificates for the
number of shares of Common Stock into which the shares of the Preferred Stock
surrendered were convertible on the date on which such automatic conversion
occurred.

                           (iii) Upon conversion of the Preferred Stock, the
Common Stock so issued shall be duly and validly issued, fully paid and
nonassessable shares of the Corporation.

                  (b) Mechanics of Conversion. No fractional shares of Common
Stock shall be issued upon conversion of the Preferred Stock. In lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the
then-effective Conversion Price for such series of Preferred Stock. Except as
provided in Section 4(a)(ii), before any holder of Preferred Stock shall be
entitled to convert the same into full shares of Common Stock, such holder shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the Corporation or of any transfer agent for the Preferred Stock and shall
give written notice by mail, postage prepaid, to the Corporation at its
principal corporate office, of the election to convert the same. The Corporation
shall, as soon as practicable thereafter, issue and deliver at such office to
such holder of Preferred Stock, a certificate or certificates for the number of
shares of Common Stock to which such holder shall be entitled as aforesaid and a
check payable to the holder in the amount of any cash payable in lieu of
fractional shares of Common Stock (after aggregating all shares of Common Stock
issuable to such holder of Preferred Stock upon conversion of the number of
shares of Preferred Stock at the time being converted). In addition, if less
than all of the shares represented by such certificates are surrendered for
conversion pursuant to Section 4(a)(i), the Corporation shall issue and deliver
to such holder a new certificate for the balance of the shares of Preferred
Stock not so converted. Except as provided in Section 4(a)(ii), such conversion
shall be deemed to have been made immediately prior to the close of business on
the date of the surrender of the shares of Preferred Stock to be converted, and
the person or persons entitled to receive the shares of Common Stock issuable
upon such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock as of such date. If the conversion is in
connection with an underwritten offer of securities registered pursuant to the
Securities Act of 1933, the conversion may, at the option of any holder
tendering such Preferred Stock for conversion, be conditioned upon the closing
with the underwriter of the sale of securities pursuant to such offering, in
which event the person(s) entitled to receive Common Stock issuable upon such
conversion of such Preferred Stock shall not be deemed to have converted such
Preferred Stock until immediately prior to the closing of such sale of
securities.

                  (c) Adjustment to Conversion Price for Diluting Issues.

                           (i) Special Definitions. For purposes of this Section
4(c), the following definitions shall apply:

<PAGE>   9

                                    (1) "Options" shall mean rights, options or
warrants to subscribe for, purchase or otherwise acquire either Common Stock or
Convertible Securities, except for those issued to officers, directors or
employees of, or consultants to, the Corporation as provided in Section
4(c)(i)(4)(B).

                                    (2) "Original Issue Date" shall mean the
date on which the first share of Series D Preferred Stock is issued.

                                    (3) "Convertible Securities" shall mean any
evidences of indebtedness, shares (other than Common Stock or Preferred Stock)
or other securities convertible into or exchangeable for Common Stock.

                                    (4) "Additional Shares of Common Stock"
shall mean all shares of Common Stock issued (or, pursuant to Section 4(c)(iii),
deemed to be issued) by the Corporation after the Original Issue Date, other
than:

                                             (A) shares of Common Stock issued
or issuable upon conversion of shares of Preferred Stock;

                                             (B) shares of capital stock issued
or issuable to officers, directors or employees of, or consultants to, the
Corporation pursuant to a stock grant, stock option plan, stock purchase plan or
other stock incentive agreement unanimously approved by the Board of Directors;

                                             (C) shares of capital stock or
securities exercisable for or convertible into shares of capital stock issued to
equipment or other lessors or institutional or other lenders or otherwise in
connection with bank or institutional loans, unanimously approved by the Board
of Directors;

                                             (D) shares of capital stock or
securities exercisable for or convertible into shares of capital stock issued as
a dividend or distribution on Preferred Stock;

                                             (E) shares of Common Stock or
Preferred Stock issuable upon exercise of warrants outstanding as of the date of
these Amended and Restated Articles of Incorporation; and

                                             (F) shares of Common Stock issued
pursuant to a transaction described in Section 4(c)(vi) hereof.

                           (ii) No Adjustment of Conversion Price. No adjustment
in the Conversion Price of a particular series of Preferred Stock shall be made
in respect of the issuance of Additional Shares of Common Stock unless the
consideration per share for an Additional Share of Common Stock issued or deemed
to be issued by the Corporation is less than the Conversion Price in effect on
the date of, and immediately prior to, such issuance, for such series of
Preferred Stock.
<PAGE>   10

                           (iii) Deemed Issue of Additional Shares of Common.

                                    (1) Options and Convertible Securities. In
the event the Corporation at any time or from time to time after the Original
Issue Date shall issue any Options or Convertible Securities or shall fix a
record date for the determination of holders of any class of securities entitled
to receive any such Options or Convertible Securities, then the maximum number
of shares (as set forth in the instrument relating thereto without regard to any
provisions contained therein for a subsequent adjustment of such number) of
Common Stock issuable upon the exercise of such Options or, in the case of
Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue or, in case such a record date shall have
been fixed, as of the close of business on such record date; provided, however,
that Additional Shares of Common Stock shall not be deemed to have been issued
with respect to a particular series of Preferred Stock unless the consideration
per share (determined pursuant to Section 4(c)(v) hereof) of such Additional
Shares of Common Stock would be less than the Conversion Price for such series
of Preferred Stock in effect on the date of and immediately prior to such issue,
or such record date, as the case may be; and, provided, further, that in any
such case in which Additional Shares of Common Stock are deemed to be issued:

                                             (A) no further adjustment in the
Conversion Price for a particular series of Preferred Stock shall be made upon
the subsequent issue of Convertible Securities or shares of Common Stock upon
the exercise of such Options or conversion or exchange of such Convertible
Securities;

                                             (B) if such Options or Convertible
Securities by their terms provide, with the passage of time or otherwise, for
any increase or decrease in the consideration payable to the Corporation, or
increase or decrease in the number of shares of Common Stock issuable, upon the
exercise, conversion or exchange thereof, the Conversion Price for a particular
series of Preferred Stock computed upon the original issue thereof (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease, insofar as it
affects such Conversion Price, but no further change in such Conversion Price
shall be made upon the exercise, conversion or exchange of such Options or
Convertible Securities;

                                             (C) if any such Options or
Convertible Securities shall expire without having been exercised or converted,
the Conversion Price for a particular series of Preferred Stock as adjusted upon
the issuance of such Options or Convertible Securities shall be readjusted to
the Conversion Price which would have been in effect had an adjustment been made
on the basis that the only Additional Shares of Common Stock so issued were the
Additional Shares of Common Stock, if any, actually issued or sold on the
exercise of such Options or the conversion of such Convertible Securities, and
such Additional Shares of Common Stock, if any, were issued or sold for the
consideration actually received by the Corporation upon such exercise, plus the
consideration, if any, actually received by the Corporation for the granting of
all such Options, whether or not exercised, plus the consideration
<PAGE>   11

received for issuing or selling the Convertible Securities actually converted
plus the consideration, if any, actually received by the Corporation (other than
by cancellation of liabilities or obligations evidenced by such Convertible
Securities) on the conversion of such Convertible Securities; and

                                             (D) no readjustment pursuant to
clauses (B) or (C) above shall have the effect of increasing the Conversion
Price for a particular series of Preferred Stock to an amount which exceeds the
lower of (i) the Conversion Price for such series of Preferred Stock on the
original adjustment date (immediately prior to the adjustment), or (ii) the
Conversion Price for such series of Preferred Stock that would have resulted
from any actual issuance of Additional Shares of Common Stock between the
original adjustment date and such readjustment date.

                           (iv) Adjustment of Conversion Price Upon Issuance of
Additional Shares of Common Stock. In the event the Corporation shall at any
time after the Original Issue Date issue Additional Shares of Common Stock
(including Additional Shares of Common Stock deemed to be issued pursuant to
Section 4(c)(iii)), without consideration or for a consideration per share less
than the Conversion Price for a series of Preferred Stock in effect on the date
of and immediately prior to such issue, then and in each such event, the
Conversion Price for such series of Preferred Stock shall be reduced,
concurrently with such issue, to a price (calculated to the nearest cent)
determined by multiplying such Conversion Price by a fraction (1) the numerator
of which shall be the number of shares of Common Stock outstanding immediately
prior to such issue plus 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 would purchase at such Conversion
Price, and (2) the denominator of which shall be the number of shares of Common
Stock outstanding immediately prior to such issue plus the number of such
Additional Shares of Common Stock so issued; provided, however, that, for the
purposes of this Section 4(c)(iv), all shares of Common Stock issuable upon
conversion of outstanding shares of Preferred Stock and shares of Common Stock
issuable upon conversion of outstanding Convertible Securities shall be deemed
to be outstanding; and, further provided, that immediately after any Additional
Shares of Common Stock are deemed issued pursuant to Section 4(c)(iii), such
Additional Shares of Common Stock shall be deemed to be outstanding.

                           (v) Determination of Consideration. For purposes of
this Section 4(c), the consideration received by the Corporation for the
issuance of any Additional Shares of Common Stock shall be computed as follows;

                                    (1) Cash and Property. Such consideration
shall :

                                             (A) insofar as it consists of cash,
be computed at the aggregate amount of cash paid therefor before deducting any
reasonable discounts, commissions or other expenses allowed, paid or incurred by
the Corporation for any underwriting or otherwise in connection with the
issuance and sale thereof;
<PAGE>   12

                                             (B) insofar as it consists of
property other than cash, be computed at the fair value thereof at the time of
such issue, as determined in good faith by the Board of Directors; and

                                             (C) in the event Additional Shares
of Common Stock are issued together with other shares or securities or other
assets of the Corporation for consideration which covers both, by the proportion
of such consideration so received, computed as provided in clauses (A) and (B)
above, as determined in good faith by the Board of Directors.

                                    (2) Options and Convertible Securities. The
consideration per share received by the Corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to Section 4(c)(iii)(1),
relating to Options and Convertible Securities, shall be determined by dividing:

                                             (A) the total amount, if any,
received or receivable by the Corporation as consideration for the issue of such
Options or Convertible Securities, plus the minimum aggregate amount of
additional consideration (as set forth in the instruments relating thereto,
without regard to any provisions contained therein for a subsequent adjustment
of such consideration) payable to the Corporation upon the exercise of such
Options or the conversion or exchange of such Convertible Securities, or in the
case of Options for Convertible Securities, the exercise of such Options for
Convertible Securities and the conversion or exchange of such Convertible
Securities, by

                                             (B) the maximum number of shares of
Common Stock (as set forth in the instruments relating thereto, without regard
to any provisions contained therein for a subsequent adjustment of such number)
issuable upon the exercise of such Options or the conversion or exchange of such
Convertible Securities.

                           (vi) Adjustments for Dividends, Distributions,
Subdivisions, Combinations or Consolidation of Common Stock.

                                    (1) Stock Dividends, Distributions or
Subdivisions. Notwithstanding any provision to the contrary in Section 4(c)(iv),
in the event the Corporation shall issue Additional Shares of Common Stock
pursuant to a stock dividend, stock distribution or subdivision, the Conversion
Price for each series of Preferred Stock in effect immediately prior to such
stock dividend, stock distribution or subdivision shall concurrently with such
stock dividend, stock distribution or subdivision, be proportionately decreased.

                                    (2) Combinations or Consolidations. In the
event the outstanding shares of Common Stock shall be combined or consolidated,
by reclassification or otherwise, into a lesser number of shares of Common
Stock, the Conversion Price for each series of Preferred Stock in effect
immediately prior to such combination or consolidation shall, concurrently with
the effectiveness of such combination or consolidation, be proportionately
increased.

<PAGE>   13

                  (d) No Impairment. The Corporation will not, through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation but will at all times in good faith assist in the
carrying out of all the provisions of this Section 4 and in the taking of all
such action as may be necessary or appropriate in order to protect the
conversion rights of each series of Preferred Stock against impairment.

                  (e) Reservation of Stock Issuable upon Conversion. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock solely for the purpose of effecting the
conversion of the Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then-outstanding shares of Preferred Stock, in addition to
such other remedies as shall be available to the holders of Preferred Stock, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purposes.

                  (f) Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Price for a series of Preferred
Stock pursuant to this Section 4, the Corporation at its expense shall promptly
compute such adjustment or readjustment in accordance with the terms hereof and
furnish to each holder of such series of Preferred Stock a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based. The Corporation shall, upon the
written request at any time of any holder of Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (i) all such
adjustments and readjustments, (ii) the Conversion Price for such series of
Preferred Stock at the time in effect, and (iii) the number of shares of Common
Stock and the amount, if any, of other property which at the time would be
received upon the conversion of such Preferred Stock.

                  (g) Notices of Record Date. In the event that the Corporation
shall propose at any time:

                           (i) to declare any dividend or distribution upon the
Common Stock, whether in cash, property, stock or other securities, whether or
not a regular cash dividend and whether or not out of earnings or earned
surplus, other than distributions to shareholders in connection with the
repurchase of Common Stock from former employees or consultants upon termination
of service to the Corporation pursuant to plans or arrangements approved by the
Board of Directors of the Corporation; or

                           (ii) to offer for subscription to all holders of any
class or series of its capital stock any additional shares of stock of any class
or series or any other rights; or

                           (iii) to effect any reclassification or
recapitalization; or

<PAGE>   14

                           (iv) to merge or consolidate with or into any other
corporation, or sell, lease or convey all or substantially all its property or
business, or to liquidate, dissolve or wind up; then, in connection with each
such event, the Corporation shall send to the holders of the Preferred Stock:

                                    (1) at least 20 days' prior written notice
of the date on which a record shall be taken for such dividend, distribution or
subscription rights (and specifying the date on which the holders of Common
Stock shall be entitled thereto) or for determining rights to vote in respect of
the matters referred to in (iii) and (iv) above; and

                                    (2) in the case of the matters referred to
in (iii) and (iv) above, at least 20 days prior written notice of the date of a
shareholders meeting at which a vote on such matters shall take place (and
specifying the date on which the holders of Common Stock shall be entitled to
exchange their Common Stock for securities or other property deliverable upon
the occurrence of such event and the amount of securities or other property
deliverable upon such event).

                                    Each such written notice shall be given
personally or by first class mail, postage prepaid, addressed to the holders of
Preferred Stock at the address for each such holder as shown on the books of the
Corporation.

         Section 5. No Reissuance of Preferred Stock. No share or shares of
Preferred Stock acquired by the Corporation by reason of redemption, purchase,
conversion or otherwise shall be reissued, and all such shares shall be
canceled, retired and eliminated from the shares which the Corporation shall be
authorized to issue.

         Section 6. Protective Provisions.

                  (a) In addition to any other rights provided by law, so long
as at least 500,000 shares of Preferred Stock (as adjusted for stock splits,
reverse stock splits, stock dividends, recapitalizations and the like) are
outstanding, the Corporation shall not, without first obtaining the affirmative
vote or written consent of the holders of two-thirds (66 2/3%) of the
outstanding shares of Preferred Stock voting together as a class (based on the
number of shares of Common Stock into which each share of Preferred Stock is
convertible, as adjusted from time to time pursuant to Section 4 hereof):

                           (i) take any action which alters or changes any of
the rights, privileges or preferences of the Preferred Stock, including without
limitation (A) increasing the aggregate number of authorized shares of Common
Stock, Preferred Stock, or any series of Preferred Stock, other than an increase
incident to Section 4(c)(vi), (B) effecting an exchange, reclassification or
cancellation of all or part of the shares of Preferred Stock, other than in
accordance with Section 4(c)(vi), and (C) effecting an exchange, or creating a
right of exchange, of all or part of the shares of another class into the shares
of Preferred Stock;

                           (ii) take any action which creates any new class or
series of shares having any right, preference, priority or power superior to or
on a parity with any such right, preference, priority or power of any series of
Preferred Stock;

<PAGE>   15

                           (iii) take any action involving (A) the sale by the
Corporation of all or a substantial portion of its assets, or (B) any
reorganization of the Corporation or the consolidation or merger of the
Corporation with or into any other corporation or corporations or other
transaction or series of related transactions in which the shareholders of
record of the Company immediately prior to such transaction or series of related
transactions will hold (by virtue of the voting securities issued as
consideration for such transaction or series of related transactions) less than
50% of the voting securities of the surviving entity (or parent, if any)
immediately after such transaction or series of related transactions.

                           (iv) amend the Corporation's Articles of
Incorporation;

                           (v) do any act or thing which would result in
taxation to the holders of Preferred Stock under Section 305 of the Internal
Revenue Act of 1986, as amended (or any comparable provision of the Internal
Revenue Code as hereinafter from time to time amended); or

                           (vi) declare or pay any dividend or other
distribution on Common Stock (other than in shares of Common Stock).

                  (b) Notwithstanding the provisions of Section 6(a) above, and
in addition to any other rights provided by law, so long as any shares of
Preferred Stock are outstanding, this Corporation shall not, without first
obtaining the affirmative vote or written consent of the holders of a majority
of the outstanding shares of a series of Preferred Stock voting together as a
separate class, take any action which alters or changes any of the rights,
privileges or preferences of such series of Preferred Stock so as to affect such
shares adversely and in a manner different than any other series of Preferred
Stock.

         Section 7. Inapplicability of Corporations Code Sections 502 and 503.
As authorized by Section 402.5 of the California Corporations Code, the
provisions of Sections 502 and 503 of the California Corporations Code shall not
apply to, and the liquidation and dividend preferences of holders of Series A
Preferred Stock and Series B Preferred Stock provided herein shall not be deemed
to be impaired by, any distributions made by the Corporation in connection with
the repurchase of the Corporation's Common Stock from former employees or
consultants upon termination of their employment or services pursuant to
agreements between the Corporation and such persons providing for the right of
such repurchase and the holders of Preferred Stock shall be deemed to have
consented to such repurchases.

                              DIRECTORS AND AGENTS

         The liability of the directors of the Corporation for monetary damages
shall be eliminated to the fullest extent permissible under California law.

provisions, agreements with agents, vote of shareholders or disinterested
directors, or otherwise, in excess of the
<PAGE>   16

indemnification otherwise permitted Section 317 of the California Corporations
Code, subject only to the applicable limits on indemnification set forth in
Section 204 of the California Corporations Code with respect to actions for
breach of duty to the Corporation or its shareholders. Any repeal or
modification of this Article IV, or the adoption of any provision of the
Articles of Incorporation inconsistent with this Article IV, shall only be
prospective and shall not adversely affect the rights under this Article IV in
effect at the time of the alleged occurrence of any action or omission to act
giving rise to indemnification.

                           PERSISTENCE SOFTWARE, INC.

         Christopher T. Keene and Christine Russell hereby certify that:

         1. The date of filing the original Certificate of Incorporation of this
corporation with the Secretary of State of the State of Delaware is __________,
1999.

         2. They are the duly elected and acting Chief Executive Officer and
Secretary, respectively, of Persistence Software, Inc., a Delaware corporation.

         3. The Certificate of Incorporation of this corporation is hereby
amended and restated to read as follows:



                                    ARTICLE I

         "The name of this corporation is Persistence Software, Inc. (the
"Corporation").

                                   ARTICLE II

         The address of the registered office of the Corporation in the State of
Delaware is:

                           1209 Orange Street
                           Wilmington, County of New Castle
                           Delaware, 19801

         The name of the Corporation's registered agent at said address is The
Corporation Trust Company.


                                   ARTICLE III

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

                                   ARTICLE IV

         (A) CLASSES OF STOCK. The Corporation is authorized to issue two
classes of stock to be designated, respectively, "Common Stock" and "Preferred
Stock." The total number of shares which the Corporation is authorized to issue
is 80,000,000 shares, each with a par value of
<PAGE>   2

$0.001 per share. 75,000,000 of such shares shall be Common Stock, and 5,000,000
of such shares shall be Preferred Stock.

         (B) The Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is hereby authorized, within the limitations and
restrictions stated in this Certificate of Incorporation, to determine or alter
the rights, preferences, privileges and restrictions granted to or imposed upon
any wholly unissued series of Preferred Stock and the number of shares
constituting any such series and the designation thereof, or any of them; and to
increase or decrease the number of shares of any series subsequent to the
issuance of shares of that series, but not below the number of shares of such
series then outstanding. In case the number of shares of any series shall be so
decreased, the shares constituting such decrease shall resume the status which
they had prior to the adoption of the resolution originally fixing the number of
shares of such series.

                                    ARTICLE V

         The number of directors of the Corporation shall be fixed from time to
time by a bylaw or amendment thereof duly adopted by the Board of Directors.

                                   ARTICLE VI

         "Listing Event" as used in this Amended and Restated Certificate of
Incorporation shall mean the first annual meeting of stockholders following such
time as the Corporation meets the criteria set forth in subdivisions (1), (2) or
(3) of Section 2115(c) the California Corporations Code as of the record date of
such meeting.

         For the management of the business and for the conduct of the affairs
of the Corporation, and in further definition, limitation and regulation of the
powers of the Corporation, its directors and its stockholders or any class
thereof, as the case may be, it is further provided that, effective upon the
occurrence of the Listing Event:


                  (i) The number of directors which shall constitute the entire
Board of Directors, and the number of directors in each class, shall be fixed
exclusively by one or more resolutions adopted from time to time by the Board of
Directors. The Board of Directors shall be divided into three classes,
designated as Class I, Class II and Class III, respectively. Directors shall be
assigned to each class in accordance with a resolution or resolutions adopted by
the Board of Directors. Until changed by a resolution of the Board of Directors,
Class I shall consist of three directors, each of whom shall be designated by
the Board of Directors; Class II shall consist of three directors, each of whom
shall be designated by the Board of Directors; and Class III shall consist of
three directors, each of whom shall be designated by the Board of Directors.


                      Upon the occurrence of the Listing Event, the terms of
office of the Class I directors shall expire, and Class I directors shall be
elected for a full term of three years. At the first annual meeting of
stockholders following the Listing Event, the term of office of the Class II
directors shall expire, and Class II directors shall be elected for a full term
of three years. At the


                                      -2-
<PAGE>   3

second annual meeting of stockholders following the Listing Event, the term of
office of the Class III directors shall expire, and Class III directors shall be
elected for a full term of three years. At each succeeding annual meeting of
stockholders, directors shall be elected for a full term of three years to
succeed the directors of the class whose terms expire at such annual meeting.

                      Any vacancies on the Board of Directors resulting from
death, resignation, disqualification, removal, or other causes shall be filled
by either (i) the affirmative vote of the holders of a majority of the voting
power of the then-outstanding shares of voting stock of the corporation entitled
to vote generally in the election of directors (the "Voting Stock") voting
together as a single class; or (ii) by the affirmative vote of a majority of the
remaining directors then in office, even though less than a quorum of the Board
of Directors. Newly created directorships resulting from any increase in the
number of directors shall, unless the Board of Directors determines by
resolution that any such newly created directorship shall be filled by the
stockholders, be filled only by the affirmative vote of the directors then in
office, even though less than a quorum of the Board of Directors. Any director
elected in accordance with the preceding sentence shall hold office for the
remainder of the full term of the class of directors in which the new
directorship was created or the vacancy occurred and until such director's
successor shall have been elected and qualified.

                      In addition to the requirements of law and any other
provisions hereof (and notwithstanding the fact that approval by a lesser vote
may be permitted by law or any other provision hereof), the affirmative vote of
the holders of at least 66 2/3 percent of the voting power of the then
outstanding shares of stock of all classes and all series of the Corporation
entitled to vote generally in the election of directors, voting together as a
single class, shall be required to amend, alter, repeal, or adopt any provision
inconsistent with this Section (i) of this Article VI.

                  (ii) There shall be no right with respect to shares of stock
of the Corporation to cumulate votes in the election of directors.

                  (iii) Any director, or the entire Board of Directors, may be
removed from office at any time (i) with cause by the affirmative vote of the
holders of at least a majority of the voting power of the then-outstanding
shares of the Voting Stock, voting together as a single class; or (ii) without
cause by the affirmative vote of the holders of at least 66-2/3% of the voting
power of the then-outstanding shares of the Voting Stock.


                                   ARTICLE VII

         No action shall be taken by the stockholders of the Corporation other
than at an annual or special meeting of the stockholders, upon due notice and in
accordance with the provisions of the Corporation's bylaws.

<PAGE>   4

                                  ARTICLE VIII

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

                                   ARTICLE IX

         The Board of Directors of the Corporation is expressly authorized to
make, alter or repeal Bylaws of the Corporation.

                                    ARTICLE X

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

                                   ARTICLE XI

         The Corporation shall have perpetual existence.

                                   ARTICLE XII

         (A) To the fullest extent permitted by the General Corporation Law of
Delaware, as the same may be amended from time to time, a director of the
Corporation shall not be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director. If
the General Corporation Law of Delaware is hereafter amended to authorize, with
the approval of a corporation's stockholders, further reductions in the
liability of the Corporation's directors for breach of fiduciary duty, then a
director of the Corporation shall not be liable for any such breach to the
fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

         (B) Any repeal or modification of the foregoing provisions of this
Article XII shall not adversely affect any right or protection of a director of
the Corporation with respect to any acts or omissions of such director occurring
prior to such repeal or modification.

                                  ARTICLE XIII

         (A) To the fullest extent permitted by applicable law, the Corporation
is also authorized to provide indemnification of (and advancement of expenses
to) such agents (and any other persons to which Delaware law permits the
Corporation to provide indemnification) though bylaw provisions, agreements with
such agents or other persons, vote of stockholders or disinterested directors or
otherwise, in excess of the indemnification and advancement otherwise permitted
by Section 145 of the Delaware General Corporation Law, subject only to limits
created by applicable Delaware law (statutory or non-statutory), with respect to
actions for breach of duty to a corporation, its stockholders, and others.

         (B) Any repeal or modification of any of the foregoing provisions of
this Article XIII shall not adversely affect any right or protection of a
director, officer, agent or other person


                                      -5-
<PAGE>   6

existing at the time of, or increase the liability of any director of the
Corporation with respect to any acts or omissions of such director, officer or
agent occurring prior to such repeal or modification."

                            FULCRUM INNOVATIONS, INC.

                                    ARTICLE I

                                CORPORATE OFFICES

         1.1      PRINCIPAL OFFICE

         The board of directors shall fix the location of the principal
executive office of the corporation at any place within or outside the State of
California. If the principal executive office is located outside such state and
the corporation has one or more business offices in such state, then the board
of directors shall fix and designate a principal business office in the State of
California.

         1.2      OTHER OFFICES

         The board of directors may at any time establish branch or subordinate
offices at any place or places where the corporation is qualified to do
business.

                                   ARTICLE II

                            MEETINGS OF SHAREHOLDERS

         2.1      PLACE OF MEETINGS

         Meetings of shareholders shall be held at any place within or outside
the State of California designated by the board of directors. In the absence of
any such designation, shareholders' meetings shall be held at the principal
executive office of the corporation.

         2.2      ANNUAL MEETING

         The annual meeting of shareholders shall be held each year on a date
and at a time designated by the board of directors. In the absence of such
designation, the annual meeting of shareholders shall be held on the 3rd Tuesday
of May in each year at 10:00 a.m. However, if such day falls on a legal holiday,
then the meeting shall be held at the same time and place on the next succeeding
full business day. At the meeting, directors shall be elected, and any other
proper business may be transacted.
<PAGE>   6
         2.3      SPECIAL MEETING

         A special meeting of the shareholders may be called at any time by the
board of directors, or by the chairman of the board, or by the president, or by
one or more shareholders holding shares in the aggregate entitled to cast not
less than ten percent (10%) of the votes at that meeting.

         If a special meeting is called by any person or persons other than the
board of directors or the president or the chairman of the board, then the
request shall be in writing, specifying the time of such meeting and the general
nature of the business proposed to be transacted, and shall be delivered
personally or sent by registered mail or by telegraphic or other facsimile
transmission to the chairman of the board, the president, any vice president or
the secretary of the corporation. The officer receiving the request shall cause
notice to be promptly given to the shareholders entitled to vote, in accordance
with the provisions of Sections 2.4 and 2.5 of these bylaws, that a meeting will
be held at the time requested by the person or persons calling the meeting, so
long as that time is not less than thirty-five (35) nor more than sixty (60)
days after the receipt of the request. If the notice is not given within twenty
(20) days after receipt of the request, then the person or persons requesting
the meeting may give the notice. Nothing contained in this paragraph of this
Section 2.3 shall be construed as limiting, fixing or affecting the time when a
meeting of shareholders called by action of the board of directors may be held.

         2.4      NOTICE OF SHAREHOLDERS' MEETINGS

         All notices of meetings of shareholders shall be sent or otherwise
given in accordance with Section 2.5 of these bylaws not less than ten (10) (or,
if sent by third-class mail pursuant to Section 2.5 of these bylaws, thirty
(30)) nor more than sixty (60) days before the date of the meeting. The notice
shall specify the place, date, and hour of the meeting and (i) in the case of a
special meeting, the general nature of the business to be transacted (no
business other than that specified in the notice may be transacted) or (ii) in
the case of the annual meeting, those matters which the board of directors, at
the time of giving the notice, intends to present for action by the shareholders
(but subject to the provisions of the next paragraph of this Section 2.4 any
proper matter may be presented at the meeting for such action). The notice of
any meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, the board intends to present
for election.


                                      -2-
<PAGE>   7
         If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the Corporations Code of California (the
"Code"), (ii) an amendment of the articles of incorporation, pursuant to Section
902 of the Code, (iii) a reorganization of the corporation, pursuant to Section
1201 of the Code, (iv) a voluntary dissolution of the corporation, pursuant to
Section 1900 of the Code, or (v) a distribution in dissolution other than in
accordance with the rights of outstanding preferred shares, pursuant to Section
2007 of the Code, then the notice shall also state the general nature of that
proposal.

         2.5      MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

         Written notice of any meeting of shareholders shall be given either (i)
personally or (ii) by first-class mail or (iii) by third-class mail but only if
the corporation has outstanding shares held of record by five hundred (500) or
more persons (determined as provided in Section 605 of the Code) on the record
date for the shareholders' meeting, or (iv) by telegraphic or other written
communication. Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the shareholder at the address of that shareholder
appearing on the books of the corporation or given by the shareholder to the
corporation for the purpose of notice. If no such address appears on the
corporation's books or is given, notice shall be deemed to have been given if
sent to that shareholder by mail or telegraphic or other written communication
to the corporation's principal executive office, or if published at least once
in a newspaper of general circulation in the county where that office is
located. Notice shall be deemed to have been given at the time when delivered
personally or deposited in the mail or sent by telegram or other means of
written communication.

         If any notice addressed to a shareholder at the address of that
shareholder appearing on the books of the corporation is returned to the
corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the shareholder
at that address, then all future notices or reports shall be deemed to have been
duly given without further mailing if the same shall be available to the
shareholder on written demand of the shareholder at the principal executive
office of the corporation for a period of one (1) year from the date of the
giving of the notice.

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

         2.6      QUORUM

         The presence in person or by proxy of the holders of a majority of the
shares entitled to vote thereat constitutes a quorum for the transaction of
business at all meetings of shareholders. The shareholders present at a duly
called or held meeting at which a quorum is present may continue to do business
until adjournment, notwithstanding the withdrawal of enough shareholders to
leave less than a quorum, if any action taken (other than adjournment) is
approved by at least a majority of the shares required to constitute a quorum.

         2.7      ADJOURNED MEETING; NOTICE

         Any shareholders' meeting, annual or special, whether or not a quorum
is present, may be adjourned from time to time by the vote of the majority of
the shares represented at that meeting, either in person or by proxy. In the
absence of a quorum, no other business may be transacted at that meeting except
as provided in Section 2.6 of these bylaws.

         When any meeting of shareholders, either annual or special, is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place are announced at the meeting at which the
adjournment is taken. However, if a new record date for the adjourned meeting is
fixed or if the adjournment is for more than forty-five (45) days from the date
set for the original meeting, then notice of the adjourned meeting shall be
given. Notice of any such adjourned meeting shall be given to each shareholder
of record entitled to vote at the adjourned meeting in accordance with the
provisions of Sections 2.4 and 2.5 of these bylaws. At any adjourned meeting the
corporation may transact any business which might have been transacted at the
original meeting.

         2.8      VOTING

         The shareholders entitled to vote at any meeting of shareholders shall
be determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of Sections 702 through 704 of the Code (relating to
voting shares held by a fiduciary, in the name of a corporation or in joint
ownership).

         The shareholders' vote may be by voice vote or by ballot; provided,
however, that any election for directors must be by ballot if demanded by any
shareholder at the meeting and before the voting has begun.

         Except as provided in the last paragraph of this Section 2.8, or as may
be otherwise provided in the articles of incorporation, each outstanding share,
regardless of class, shall be entitled to


                                      -4-
<PAGE>   9
one vote on each matter submitted to a vote of the shareholders. Any shareholder
entitled to vote on any matter may vote part of the shares in favor of the
proposal and refrain from voting the remaining shares or, except when the matter
is the election of directors, may vote them against the proposal; but, if the
shareholder fails to specify the number of shares which the shareholder is
voting affirmatively, it will be conclusively presumed that the shareholder's
approving vote is with respect to all shares which the shareholder is entitled
to vote.

         If a quorum is present, the affirmative vote of the majority of the
shares represented and voting at a duly held meeting (which shares voting
affirmatively also constitute at least a majority of the required quorum) shall
be the act of the shareholders, unless the vote of a greater number or a vote by
classes is required by the Code or by the articles of incorporation.

         At a shareholders' meeting at which directors are to be elected, a
shareholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes which such shareholder normally
is entitled to cast) if the candidates' names have been placed in nomination
prior to commencement of the voting and the shareholder has given notice prior
to commencement of the voting of the shareholder's intention to cumulate votes.
If any shareholder has given such a notice, then every shareholder entitled to
vote may cumulate votes for candidates in nomination either (i) by giving one
candidate a number of votes equal to the number of directors to be elected
multiplied by the number of votes to which that shareholder's shares are
normally entitled or (ii) by distributing the shareholder's votes on the same
principle among any or all of the candidates, as the shareholder thinks fit. The
candidates receiving the highest number of affirmative votes, up to the number
of directors to be elected, shall be elected; votes against any candidate and
votes withheld shall have no legal effect.

         2.9      VALIDATION OF MEETINGS; WAIVER OF NOTICE; CONSENT

         The transactions of any meeting of shareholders, either annual or
special, however called and noticed, and wherever held, shall be as valid as
though they had been taken at a meeting duly held after regular call and notice,
if a quorum be present either in person or by proxy, and if, either before or
after the meeting, each person entitled to vote, who was not present in person
or by proxy, signs a written waiver of notice or a consent to the holding of the
meeting or an approval of the minutes thereof. The waiver of notice or consent
or approval need not specify either the business to be transacted or the purpose
of any annual or special meeting of shareholders, except that if action is taken
or proposed to be taken for approval of any of those matters specified in the
second


                                      -5-
<PAGE>   10
paragraph of Section 2.4 of these bylaws, the waiver of notice or consent or
approval shall state the general nature of the proposal. All such waivers,
consents, and approvals shall be filed with the corporate records or made a part
of the minutes of the meeting.

         Attendance by a person at a meeting shall also constitute a waiver of
notice of and presence at that meeting, except when the person objects at the
beginning of the meeting to the transaction of any business because the meeting
is not lawfully called or convened. Attendance at a meeting is not a waiver of
any right to object to the consideration of matters required by the Code to be
included in the notice of the meeting but not so included, if that objection is
expressly made at the meeting.

         2.10     SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

         Any action which may be taken at any annual or special meeting of
shareholders may be taken without a meeting and without prior notice, if a
consent in writing, setting forth the action so taken, is signed by the holders
of outstanding shares having not less than the minimum number of votes that
would be necessary to authorize or take that action at a meeting at which all
shares entitled to vote on that action were present and voted.

         In the case of election of directors, such a consent shall be effective
only if signed by the holders of all outstanding shares entitled to vote for the
election of directors. However, a director may be elected at any time to fill
any vacancy on the board of directors, provided that it was not created by
removal of a director and that it has not been filled by the directors, by the
written consent of the holders of a majority of the outstanding shares entitled
to vote for the election of directors.

         All such consents shall be maintained in the corporate records. Any
shareholder giving a written consent, or the shareholder's proxy holders, or a
transferee of the shares, or a personal representative of the shareholder, or
their respective proxy holders, may revoke the consent by a writing received by
the secretary of the corporation before written consents of the number of shares
required to authorize the proposed action have been filed with the secretary.

         If the consents of all shareholders entitled to vote have not been
solicited in writing and if the unanimous written consent of all such
shareholders has not been received, then the secretary shall give prompt notice
of the corporate action approved by the shareholders without a meeting. Such
notice shall be given to those shareholders entitled to vote who have not
consented in writing and shall be given in the manner specified in Section 2.5
of these bylaws. In the case of approval of (i) a contract or


                                      -6-
<PAGE>   11
transaction in which a director has a direct or indirect financial interest,
pursuant to Section 310 of the Code, (ii) indemnification of a corporate
"agent," pursuant to Section 317 of the Code, (iii) a reorganization of the
corporation, pursuant to Section 1201 of the Code, and (iv) a distribution in
dissolution other than in accordance with the rights of outstanding preferred
shares, pursuant to Section 2007 of the Code, the notice shall be given at least
ten (10) days before the consummation of any action authorized by that approval.

         2.11     RECORD DATE FOR SHAREHOLDER NOTICE; VOTING; GIVING CONSENTS

         For purposes of determining the shareholders entitled to notice of any
meeting or to vote thereat or entitled to give consent to corporate action
without a meeting, the board of directors may fix, in advance, a record date,
which shall not be more than sixty (60) days nor less than ten (10) days before
the date of any such meeting nor more than sixty (60) days before any such
action without a meeting, and in such event only shareholders of record on the
date so fixed are entitled to notice and to vote or to give consents, as the
case may be, notwithstanding any transfer of any shares on the books of the
corporation after the record date, except as otherwise provided in the Code.

         If the board of directors does not so fix a record date:

                  (a) the record date for determining shareholders entitled to
notice of or to vote at a meeting of shareholders shall be at the close of
business on the business day next preceding the day on which notice is given or,
if notice is waived, at the close of business on the business day next preceding
the day on which the meeting is held; and

                  (b) the record date for determining shareholders entitled to
give consent to corporate action in writing without a meeting, (i) when no prior
action by the board has been taken, shall be the day on which the first written
consent is given, or (ii) when prior action by the board has been taken, shall
be at the close of business on the day on which the board adopts the resolution
relating to that action, or the sixtieth (60th) day before the date of such
other action, whichever is later.

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


                                      -7-
<PAGE>   12
         2.12     PROXIES

         Every person entitled to vote for directors, or on any other matter,
shall have the right to do so either in person or by one or more agents
authorized by a written proxy signed by the person and filed with the secretary
of the corporation. A proxy shall be deemed signed if the shareholder's name is
placed on the proxy (whether by manual signature, typewriting, telegraphic
transmission or otherwise) by the shareholder or the shareholder's
attorney-in-fact. A validly executed proxy which does not state that it is
irrevocable shall continue in full force and effect unless (i) the person who
executed the proxy revokes it prior to the time of voting by delivering a
writing to the corporation stating that the proxy is revoked or by executing a
subsequent proxy and presenting it to the meeting or by voting in person at the
meeting, or (ii) written notice of the death or incapacity of the maker of that
proxy is received by the corporation before the vote pursuant to that proxy is
counted; provided, however, that no proxy shall be valid after the expiration of
eleven (11) months from the date of the proxy, unless otherwise provided in the
proxy. The dates contained on the forms of proxy presumptively determine the
order of execution, regardless of the postmark dates on the envelopes in which
they are mailed. The revocability of a proxy that states on its face that it is
irrevocable shall be governed by the provisions of Sections 705(e) and 705(f) of
the Code.

         2.13     INSPECTORS OF ELECTION

         Before any meeting of shareholders, the board of directors may appoint
an inspector or inspectors of election to act at the meeting or its adjournment.
If no inspector of election is so appointed, then the chairman of the meeting
may, and on the request of any shareholder or a shareholder's proxy shall,
appoint an inspector or inspectors of election to act at the meeting. The number
of inspectors shall be either one (1) or three (3). If inspectors are appointed
at a meeting pursuant to the request of one (1) or more shareholders or proxies,
then the holders of a majority of shares or their proxies present at the meeting
shall determine whether one (1) or three (3) inspectors are to be appointed. If
any person appointed as inspector fails to appear or fails or refuses to act,
then the chairman of the meeting may, and upon the request of any shareholder or
a shareholder's proxy shall, appoint a person to fill that vacancy.

         Such inspectors shall:

                  (a) determine the number of shares outstanding and the voting
power of each, the number of shares represented at the meeting, the existence of
a quorum, and the authenticity, validity, and effect of proxies;


                                      -8-
<PAGE>   13
                  (b) receive votes, ballots or consents;

                  (c) hear and determine all challenges and questions in any way
arising in connection with the right to vote;

                  (d) count and tabulate all votes or consents;

                  (e) determine when the polls shall close;

                  (f) determine the result; and

                  (g) do any other acts that may be proper to conduct the
election or vote with fairness to all shareholders.

                                   ARTICLE III

                                    DIRECTORS

         3.1      POWERS

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

         3.2      NUMBER OF DIRECTORS

         The number of directors of the corporation shall be eight(8) until
changed, within the limits specified above, by a bylaw amending this Section
3.2, duly adopted by the board of directors or by the shareholders. The
indefinite number of directors may be changed, or a definite number may be fixed
without provision for an indefinite number, by a duly adopted amendment to the
articles of incorporation or by an amendment to this bylaw duly adopted by the
vote or written consent of holders of a majority of the outstanding shares
entitled to vote; provided, however, that an amendment reducing the fixed number
or the minimum number of directors to a number less than five (5) cannot be
adopted if the votes cast against its adoption at a meeting, or the shares not
consenting in the case of an action by written consent, are equal to more than
sixteen and two-thirds percent (16-2/3%) of the outstanding shares entitled to
vote thereon. No amendment may change the stated maximum number of authorized
directors to a number greater than two (2) times the stated minimum number of
directors minus one (1).


                                      -9-
<PAGE>   14
         No reduction of the authorized number of directors shall have the
effect of removing any director before that director's term of office expires.

         3.3      ELECTION AND TERM OF OFFICE OF DIRECTORS

         Directors shall be elected at each annual meeting of shareholders to
hold office until the next annual meeting. Each director, including a director
elected to fill a vacancy, shall hold office until the expiration of the term
for which elected and until a successor has been elected and qualified.

         3.4      RESIGNATION AND VACANCIES

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

         Vacancies in the board of directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote or
written consent of the shareholders or by court order may be filled only by the
affirmative vote of a majority of the shares represented and voting at a duly
held meeting at which a quorum is present (which shares voting affirmatively
also constitute a majority of the required quorum), or by the unanimous written
consent of all shares entitled to vote thereon. Each director so elected shall
hold office until the next annual meeting of the shareholders and until a
successor has been elected and qualified.

         A vacancy or vacancies in the board of directors shall be deemed to
exist (i) in the event of the death, resignation or removal of any director,
(ii) if the board of directors by resolution declares vacant the office of a
director who has been declared of unsound mind by an order of court or convicted
of a felony,(iii) if the authorized number of directors is increased, or (iv) if
the shareholders fail, at any meeting of shareholders at which any director or
directors are elected, to elect the number of directors to be elected at that
meeting.

         The shareholders may elect a director or directors at any time to fill
any vacancy or vacancies not filled by the directors, but any such election
other than to fill a vacancy created by removal,


                                      -10-
<PAGE>   15

purposes of this Article VI, a "director" or "officer" of the corporation
includes any person (i) who is or was a director or officer of the corporation,
(ii) who is or was serving at the request of the corporation as a director or
officer of another corporation, partnership, joint venture, trust or other
enterprise, or (iii) who was a director or officer of a corporation which was a

Code), judgments, fines, settlements, and other amounts actually and reasonably
incurred in connection with any proceeding (as defined in Section 317(a) of the
Code), arising by reason of the fact that such person is or was an agent of the

corporation (other than a director or officer) includes any person (i) who is or
was an employee or agent of the corporation, (ii) who is or was serving at the
request of the corporation as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was an
employee or agent of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

         6.3      PAYMENT OF EXPENSES IN ADVANCE

         Expenses incurred in defending any civil or criminal action or
proceeding for which indemnification is required pursuant to Section 6.1 or for
which indemnification is permitted pursuant to Section 6.2 following
authorization thereof by the Board of


                                      -18-
<PAGE>   23
Directors shall be paid by the corporation in advance of the final disposition
of such action or proceeding upon receipt of an undertaking by or on behalf of
the indemnified party to repay such amount if it shall ultimately be determined
that the indemnified party is not entitled to be indemnified as authorized in
this Article VI.

         6.4      INDEMNITY NOT EXCLUSIVE

         The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the Articles of
Incorporation.

         6.5      INSURANCE INDEMNIFICATION

         The corporation shall have the power to purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent of

or not the corporation would have the power to indemnify him against such
liability under the provisions of this Article VI.

         6.6      CONFLICTS

         No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

                  (1) That it would be inconsistent with a provision of the
Articles of Incorporation, these bylaws, a resolution of the shareholders or an
agreement in effect at the time of the accrual of the alleged cause of the
action asserted in the proceeding in which the expenses were incurred or other
amounts were paid, which prohibits or otherwise limits indemnification; or

                  (2) That it would be inconsistent with any condition expressly
imposed by a court in approving a settlement.

         A shareholder or shareholders of the corporation who holds at least

agent of the corporation, on written demand and on the tender of such transfer
agent's usual charges for such list, a list of the names and addresses of the
shareholders who are entitled to vote for the election of directors, and their
shareholdings, as of the most recent record date for which that list has been
compiled or as of a date specified by the shareholder after the date of demand.
Such list shall be made available to any such shareholder by the transfer agent
on or before the later of five (5) days after the demand is received or five (5)
days after the date specified in the demand as the date as of which the list is

written demand of any shareholder or holder of a voting trust certificate, at
any time during usual business hours, for a purpose reasonably related to the
holder's interests as a shareholder or as the holder of a voting trust
certificate.

         Any inspection and copying under this Section 7.1 may be made in person

reasonable times during office hours. If the principal executive office of the


                                      -20-
<PAGE>   25
corporation is outside the State of California and the corporation has no
principal business office in such state, then the secretary shall, upon the
written request of any shareholder, furnish to that shareholder a copy of these
bylaws as amended to date.

         7.3      MAINTENANCE AND INSPECTION OF OTHER CORPORATE RECORDS

         The accounting books and records and the minutes of proceedings of the
shareholders, of the board of directors, and of any committee or committees of

by the board of directors or, in absence of such designation, at the principal
executive office of the corporation. The minutes shall be kept in written form,
and the accounting books and records shall be kept either in written form or in
any other form capable of being converted into written form.

         The minutes and accounting books and records shall be open to
inspection upon the written demand of any shareholder or holder of a voting
trust certificate, at any reasonable time during usual business hours, for a
purpose reasonably related to the holder's interests as a shareholder or as the
holder of a voting trust certificate. The inspection may be made in person or by
an agent or attorney and shall include the right to copy and make extracts. Such
rights of inspection shall extend to the records of each subsidiary corporation
of the corporation.

         7.4      INSPECTION BY DIRECTORS

         Every director shall have the absolute right at any reasonable time to
inspect all books, records, and documents of every kind as well as the physical
properties of the corporation and each of its subsidiary corporations. Such

right of inspection includes the right to copy and make extracts of documents.

         7.5      ANNUAL REPORT TO SHAREHOLDERS; WAIVER

         The board of directors shall cause an annual report to be sent to the
shareholders not later than one hundred twenty (120) days after the close of the
fiscal year adopted by the corporation. Such report shall be sent at least
fifteen (15) days (or, if sent by third-class mail, thirty-five (35) days)
before the annual meeting of shareholders to be held during the next fiscal year
and in the manner specified in Section 2.5 of these bylaws for giving notice to
shareholders of the corporation.

         The annual report shall contain (i) a balance sheet as of the end of

<PAGE>   26
report of independent accountants or, if there is no such report, the
certificate of an authorized officer of the corporation that the statements were
prepared without audit from the books and records of the corporation.

         The foregoing requirement of an annual report shall be waived so long
as the shares of the corporation are held by fewer than one hundred (100)
holders of record.

         7.6      FINANCIAL STATEMENTS

         If no annual report for the fiscal year has been sent to shareholders,
then the corporation shall, upon the written request of any shareholder made
more than one hundred twenty (120) days after the close of such fiscal year,
deliver or mail to the person making the request, within thirty (30) days
thereafter, a copy of a balance sheet as of the end of such fiscal year and an
income statement and statement of changes in financial position for such fiscal
year.

         If a shareholder or shareholders holding at least five percent (5%) of
the outstanding shares of any class of stock of the corporation makes a written
request to the corporation for an income statement of the corporation for the
three-month, six-month or nine-month period of the then current fiscal year
ended more than thirty (30) days before the date of the request, and for a
balance sheet of the corporation as of the end of that period, then the chief
financial officer shall cause that statement to be prepared, if not already
prepared, and shall deliver personally or mail that statement or statements to
the person making the request within thirty (30) days after the receipt of the
request. If the corporation has not sent to the shareholders its annual report
for the last fiscal year, the statements referred to in the first paragraph of
this Section 7.6 shall likewise be delivered or mailed to the shareholder or
shareholders within thirty (30) days after the request.

         The quarterly income statements and balance sheets referred to in this
section shall be accompanied by the report, if any, of any independent
accountants engaged by the corporation or by the certificate of an authorized
officer of the corporation that the financial statements were prepared without
audit from the books and records of the corporation.

         7.7      REPRESENTATION OF SHARES OF OTHER CORPORATIONS

         The chairman of the board, the president, any vice president, the chief
financial officer, the secretary or assistant secretary of this corporation, or
any other person authorized by the board of directors or the president or a vice
president, is authorized to


                                      -22-
<PAGE>   27
vote, represent, and exercise on behalf of this corporation all rights incident
to any and all shares of any other corporation or corporations standing in the
name of this corporation. The authority herein granted may be exercised either
by such person directly or by any other person authorized to do so by proxy or
power of attorney duly executed by such person having the authority.

                                  ARTICLE VIII

                                 GENERAL MATTERS

         8.1      RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

         For purposes of determining the shareholders entitled to receive
payment of any dividend or other distribution or allotment of any rights or the
shareholders entitled to exercise any rights in respect of any other lawful
action (other than action by shareholders by written consent without a meeting),
the board of directors may fix, in advance, a record date, which shall not be
more than sixty (60) days before any such action. In that case, only
shareholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided in the Code.

         If the board of directors does not so fix a record date, then the
record date for determining shareholders for any such purpose shall be at the
close of business on the day on which the board adopts the applicable resolution
or the sixtieth (60th) day before the date of that action, whichever is later.

         8.2      CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

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

         8.3      CORPORATE CONTRACTS AND INSTRUMENTS: HOW EXECUTED

         The board of directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or


                                      -23-
<PAGE>   28
confined to specific instances. Unless so authorized or ratified by the board of
directors or within the agency power of an officer, no officer, agent or
employee shall have any power or authority to bind the corporation by any
contract or engagement or to pledge its credit or to render it liable for any
purpose or for any amount.

         8.4      CERTIFICATES FOR SHARES

         A certificate or certificates for shares of the corporation shall be
issued to each shareholder when any of such shares are fully paid. The board of
directors may authorize the issuance of certificates for shares partly paid
provided that these certificates shall state the total amount of the
consideration to be paid for them and the amount actually paid. All certificates
shall be signed in the name of the corporation by the chairman of the board or
the vice chairman of the board or the president or a vice president and by the
chief financial officer or an assistant treasurer or the secretary or an
assistant secretary, certifying the number of shares and the class or series of
shares owned by the shareholder. Any or all of the signatures on the certificate
may be facsimile.

         In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed on a certificate ceases to be that
officer, transfer agent or registrar before that certificate is issued, it may
be issued by the corporation with the same effect as if that person were an
officer, transfer agent or registrar at the date of issue.

         8.5      LOST CERTIFICATES

         Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time. The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

         8.6      CONSTRUCTION; DEFINITIONS

         Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Code shall govern the construction of these
bylaws. Without limiting the generality of


                                      -24-
<PAGE>   29
this provision, the singular number includes the plural, the plural number
includes the singular, and the term "person" includes both a corporation and a
natural person.

                                   ARTICLE IX

                                   AMENDMENTS

         9.1      AMENDMENT BY SHAREHOLDERS

         New bylaws may be adopted or these bylaws may be amended or repealed by
the vote or written consent of holders of a majority of the outstanding shares
entitled to vote; provided, however, that if the articles of incorporation of
the corporation set forth the number of authorized directors of the corporation,
then the authorized number of directors may be changed only by an amendment of
the articles of incorporation.

         9.2      AMENDMENT BY DIRECTORS

         Subject to the rights of the shareholders as provided in Section 9.1 of
these bylaws, bylaws, other than a bylaw or an amendment of a bylaw changing the
authorized number of directors (except to fix the authorized number of directors
pursuant to a bylaw providing for a variable number of directors), may be
adopted, amended or repealed by the board of directors.

                                    ARTICLE I

                                CORPORATE OFFICES

         1.1      REGISTERED OFFICE.

State of Delaware is 1209 Orange Street, Wilmington, Delaware, County of New
Castle, 19801. The name of its registered agent at such address is The

         1.2      OTHER OFFICES.

                  The Board of Directors may at any time establish other offices
at any place or places where the corporation is qualified to do business.

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

         2.1      PLACE OF MEETINGS.

                  Meetings of stockholders shall be held at any place, within or
outside the State of Delaware, designated by the Board of Directors. In the
absence of any such designation, stockholders' meetings shall be held at the
registered office of the corporation.

         2.2      ANNUAL MEETING.

                  (a) The annual meeting of stockholders shall be held each year
on a date and at a time designated by the Board of Directors. At the meeting,
directors shall be elected and any other proper business may be transacted.

                  (b) Nominations of persons for election to the Board of
Directors of the corporation and the proposal of business to be transacted by
the stockholders may be made at an annual meeting of stockholders (i) pursuant
to the corporation's notice with respect to such 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 Section 2.2, who is entitled to vote at the meeting and who
has complied with the notice procedures set forth in this Section 2.2.

<PAGE>   5

(iii) of paragraph (b) of this Section 2.2, the stockholder must have given
timely notice thereof in writing to the secretary of the corporation and such
business must be a proper matter for stockholder action under the General
Corporation Law of Delaware. To be timely, a stockholder's notice shall be
delivered to the secretary at the principal executive offices of the corporation
not less than twenty (20) days nor more than ninety (90) days prior to the first
anniversary of the preceding year's annual meeting of stockholders; provided,
however, that in the event that the date of the annual meeting is more than
thirty (30) days prior to or more than sixty (60) days after such anniversary
date, notice by the stockholder to be timely must be so delivered not earlier
than the ninetieth (90th) day prior to such annual meeting and not later than
the close of business on the later of the twentieth (20th) day prior to such
annual meeting or the tenth (10th) 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 such business, 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) 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 this Section 2.2. The chairman of the meeting shall
determine whether a nomination or any business proposed to be transacted by the
stockholders has been properly brought before the meeting and, if any proposed
nomination or business has not been properly brought before the meeting, the
chairman shall declare that such proposed business or nomination shall not be
presented for stockholder action at the meeting.

                  (e) For purposes of this Section 2.2, "public announcement"
shall mean disclosure in a press release reported by the Dow Jones News Service,
Associated Press or a comparable national news service.

                  (f) Nothing in this Section 2.2 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.

         2.3      SPECIAL MEETING.
<PAGE>   6

                   (a) A special meeting of the stockholders may be called at
any time by the Board of Directors, or by the chairman of the board, or by the
president.

                   (b) Nominations of persons for election to the Board of
Directors may be made at a special meeting of stockholders at which directors
are to be selected pursuant to such notice of meeting (i) by or at the direction
of the Board of Directors or (ii) by any stockholder of the corporation who is a
stockholder of record at the time of giving of notice provided for in Section
2.5, who shall be entitled to vote at the meeting and who complies with the
notice procedures set forth in Section 2.5.

         2.4      NOTICE OF STOCKHOLDER'S MEETINGS; AFFIDAVIT OF NOTICE.

                  All notices of meetings of stockholders shall be in writing
and shall be sent or otherwise given in accordance with this Section 2.4 of
these Bylaws not less than ten (10) nor more than sixty (60) days before the
date of the meeting to each stockholder entitled to vote at such meeting (or
such longer or shorter time as is required by Section 2.5 of these Bylaws, if
applicable). The notice shall specify the place, date, and hour of the meeting,
and, in the case of a special meeting, the purpose or purposes for which the
meeting is called.

                  Written notice of any meeting of stockholders, if mailed, is
given when deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation. An
affidavit of the secretary or an assistant secretary or of the transfer agent of
the corporation that the notice has been given shall, in the absence of fraud,
be prima facie evidence of the facts stated therein.

         2.5      ADVANCE NOTICE OF STOCKHOLDER NOMINEES.

                  Only persons who are nominated in accordance with the
procedures set forth in this Section 2.5 shall be eligible for election as
directors. Nominations of persons for election to the board of directors of the
corporation may be made at a meeting of stockholders by or at the direction of
the board of directors or by any stockholder of the corporation entitled to vote
for the election of directors at the meeting who complies with the notice
procedures set forth in this Section 2.5. Such nominations, other than those
made by or at the direction of the board of directors, shall be made pursuant to
timely notice in writing to the secretary of the corporation. To be timely, a
stockholder's notice shall be delivered to or mailed and received at the
principal executive offices of the corporation not less than sixty (60) days nor
more than ninety (90) days prior to the meeting; provided, however, that in the
event that less than sixty (60) 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 so received not later than the close of business on the
10th day following the day on which such notice of the date of the meeting was
mailed or such public disclosure was made. Such stockholder's notice shall set
forth (a) as to each person whom the stockholder proposes to nominate for
election or re-election as a Director, (i) the name, age, business address and
residence address of such person, (ii) the principal occupation or employment of
such person, (iii) the class and number of shares of the corporation which are
beneficially owned by such person and (iv) any other information relating to
such person that is required to be disclosed in solicitations of proxies for
election of Directors, or is otherwise
<PAGE>   7

required, in each case pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (including, without limitation, such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director if elected); and (b) as to the stockholder giving the notice (i) the
name and address, as they appear on the corporation's books, of such stockholder
and (ii) the class and number of shares of the corporation which are
beneficially owned by such stockholder. At the request of the Board of Directors
any person nominated by the Board of Directors for election as a director shall
furnish to the secretary of the corporation that information required to be set
forth in a stockholder's notice of nomination which pertains to the nominee. No
person shall be eligible for election as a director of the corporation unless
nominated in accordance with the procedures set forth in this Section 2.5. The
Chairman of the meeting shall, if the facts warrant, determine and declare to
the meeting that a nomination was not made in accordance with the procedures
prescribed by the Bylaws, and if he or she should so determine, he or she shall
so declare to the meeting and the defective nomination shall be disregarded.

         2.6      QUORUM.

         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 is not present or represented at any
meeting of the stockholders, then either (a) the chairman of the meeting or (b)
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 is present or
represented. At such adjourned meeting at which a quorum is present or
represented, any business may be transacted that might have been transacted at
the meeting as originally noticed.

         2.7      ADJOURNED MEETING; NOTICE.

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

         2.8      CONDUCT OF BUSINESS.

                  The chairman of any meeting of stockholders shall determine

         2.9      VOTING.

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

                  (b) Except as may be otherwise provided in the certificate of
incorporation, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder.

         2.10     WAIVER OF NOTICE.

                  Whenever notice is required to be given under any provision of
the General Corporation Law of Delaware or of the certificate of incorporation
or these Bylaws, a written waiver thereof, signed by the person entitled to
notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the stockholders need be specified in any written
waiver of notice unless so required by the certificate of incorporation or these
Bylaws.

         2.11     RECORD DATE FOR STOCKHOLDER NOTICE; VOTING.

                  In order that the corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty (60) nor less than ten (10) days before the
date of such meeting, nor more than sixty (60) days prior to any other action.
If the Board of Directors does not so fix a record date:

                  (a) The record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held.

                   (b) The record date for determining stockholders for any
other purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto.

                  A determination of stockholders of record entitled to notice
of or to vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board of Directors may fix a new record
date for the adjourned meeting.
<PAGE>   9

         2.12     PROXIES.

                  Each stockholder entitled to vote at a meeting of stockholders
may authorize another person or persons to act for such stockholder by a written
proxy, signed by the stockholder and filed with the secretary of the
corporation, but no such proxy shall be voted or acted upon after three (3)
years from its date, unless the proxy provides for a longer period. A proxy
shall be deemed signed if the stockholder's name is placed on the proxy (whether
by manual signature, typewriting, telegraphic transmission or otherwise) by the
stockholder or the stockholder's attorney-in-fact. The revocability of a proxy
that states on its face that it is irrevocable shall be governed by the
provisions of Section 212(e) of the General Corporation Law of Delaware.

                                   ARTICLE III
                                    DIRECTORS

         3.1      POWERS.

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

         3.2      NUMBER OF DIRECTORS.

                  The number of directors constituting the entire Board of
Directors shall be eight (8).

         3.3      ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS.

                  Except as provided in Section 3.4 of these Bylaws, directors
shall be elected at each annual meeting of stockholders to hold office until the
next annual meeting. Directors need not be stockholders unless so required by
the certificate of incorporation or these Bylaws, wherein other qualifications
for directors may be prescribed. Each director, including a director elected to
fill a vacancy, shall hold office until his or her successor is elected and
qualified or until his or her earlier resignation or removal.

                  Elections of directors need not be by written ballot.

         3.4      RESIGNATION AND VACANCIES.

                  Any director may resign at any time upon written notice to the
attention of the Secretary of the corporation. When one or more directors so
resigns and the resignation is effective at a future date, a majority of the
directors then in office, including those who have so resigned, shall have power
to fill such vacancy or vacancies, the vote thereon to take effect when such
resignation or resignations shall become effective, and each director so chosen
shall hold
<PAGE>   10

office as provided in this section in the filling of other vacancies. A vacancy
created by the removal of a director by the vote of the stockholders or by court
order may be filled only by the affirmative vote of a majority of the shares
represented and voting at a duly held meeting at which a quorum is present
(which shares voting affirmatively also constitute a majority of the quorum.
Each director so elected shall hold office until the next annual meeting of the
stockholders and until a successor has been elected and qualified.

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

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

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

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

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

         3.5      PLACE OF MEETINGS; MEETINGS BY TELEPHONE.

                  The Board of Directors of the corporation may hold meetings,
both regular and special, either within or outside the State of Delaware.

                  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
<PAGE>   11

the meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

         3.6      REGULAR MEETINGS.

                  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.

         3.7      SPECIAL MEETINGS; NOTICE.

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

                  Notice of the time and place of special meetings shall be
delivered personally or by telephone to each director or sent by first-class
mail or telegram, charges prepaid, addressed to each director at that director's
address as it is shown on the records of the corporation. If the notice is
mailed, it shall be deposited in the United States mail at least four (4) days
before the time of the holding of the meeting. If the notice is delivered
personally or by telephone or by telegram, it shall be delivered personally or
by telephone or to the telegraph company at least forty-eight (48) hours before
the time of the holding of the meeting. Any oral notice given personally or by
telephone may be communicated either to the director or to a person at the
office of the director who the person giving the notice has reason to believe
will promptly communicate it to the director. The notice need not specify the
purpose or the place of the meeting, if the meeting is to be held at the
principal executive office of the corporation.

         3.8      QUORUM.

                  At all meetings of the Board of Directors, a majority of the
authorized number of 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 is not present at any meeting of the Board of
Directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

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

         3.9      WAIVER OF NOTICE.

                  Whenever notice is required to be given under any provision of
the General Corporation Law of Delaware or of the certificate of incorporation
or these Bylaws, a written waiver thereof, signed by the person entitled to
notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall
<PAGE>   12

constitute a waiver of notice of such meeting, except when the person attends a
meeting for the express purpose of objecting, at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the directors, or members of a committee of
directors, need be specified in any written waiver of notice unless so required
by the certificate of incorporation or these Bylaws.

         3.10     BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING.

                  Unless otherwise restricted by the certificate of
incorporation or 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. Written consents representing
actions taken by the board or committee may be executed by telex, telecopy or
other facsimile transmission, and such facsimile shall be valid and binding to
the same extent as if it were an original.

         3.11     FEES AND COMPENSATION OF DIRECTORS.

                  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. No such compensation shall preclude any
director from serving the corporation in any other capacity and receiving
compensation therefor.

         3.12     APPROVAL OF LOANS TO OFFICERS.

                  The corporation may lend money to, or guarantee any obligation
of, or otherwise assist any officer or other employee of the corporation or of
its subsidiary, including any officer or employee who is a director of the
corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
corporation. The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the Board of
Directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation. Nothing in this section contained shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

         3.13     REMOVAL OF DIRECTORS.

                  Unless otherwise restricted by statute, by the certificate of
incorporation or by these Bylaws, any director or the entire Board of Directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors; provided, however,
that if the stockholders of the corporation are entitled to cumulative voting,
if less than the entire Board of Directors is to be removed, no director may be
removed without cause if the votes cast against his removal would be sufficient
to elect him if then cumulatively voted at an election of the entire Board of
Directors.
<PAGE>   13

                  No reduction of the authorized number of directors shall have
the effect of removing any director prior to the expiration of such director's
term of office.

         3.14     CHAIRMAN OF THE BOARD OF DIRECTORS.

                  The corporation may also have, at the discretion of the Board
of Directors, a chairman of the Board of Directors who shall not be considered

designate one 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 or disqualification of a member of a committee, the member or
members thereof present at any meeting and not disqualified from voting, whether
or not such member or members 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 or in the Bylaws of the
corporation, 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 to (a) amend the certificate of incorporation (except that a committee
may, to the extent authorized in the resolution or resolutions providing for the
issuance of shares of stock adopted by the Board of Directors as provided in
Section 151(a) of the General Corporation Law of Delaware, fix the designations
and any of the preferences or rights of such shares relating to dividends,
redemption, dissolution, any distribution of assets of the corporation or the
conversion into, or the exchange of such shares for, shares of any other class
or classes or any other series of the same or any other class or classes of
stock of the corporation or fix the number of shares of any series of stock or
authorize the increase or decrease of the shares of any series), (b) adopt an
agreement of merger or consolidation under Sections 251 or 252 of the General

stock, or to adopt a certificate of ownership and merger pursuant to Section 253
of the General Corporation Law of Delaware.

however, that the time of regular meetings of committees may be determined
either by resolution of the Board of Directors or by resolution of the
committee, that special meetings of committees may also be called by resolution
of the Board of Directors and that notice of special meetings of committees
shall also be given to all alternate members, who shall have the right to attend
all meetings of the committee. The Board of Directors may adopt rules for the
government of any committee not inconsistent with the provisions of these
Bylaws.

                  The corporation shall, to the maximum extent and in the manner
permitted by the General Corporation Law of Delaware, indemnify each of its
directors and officers against expenses (including attorneys' fees), judgments,
fines, settlements and other amounts actually and reasonably incurred in
connection with any proceeding, arising by reason of the fact that such person
is or was an agent of the corporation. For purposes of this Section 6.1, a
"director" or "officer" of the corporation includes any person (a) who is or was
a director or officer of the corporation, (b) who is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or (c) who was a director
or officer of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

         6.2      INDEMNIFICATION OF OTHERS.

                  The corporation shall have the power, to the maximum extent
and in the manner permitted by the General Corporation Law of Delaware, to
indemnify each of its employees and agents (other than directors and officers)
against expenses (including attorneys' fees), judgments, fines, settlements and
other amounts actually and reasonably incurred in connection with any
proceeding, arising by reason of the fact that such person is or was an agent of
the corporation. For purposes of this Section 6.2, an "employee" or "agent" of
the corporation (other than a director or officer) includes any person (a) who
is or was an employee or agent of the corporation, (b) who is or was serving at
the request of the corporation as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, or (c) who was an
<PAGE>   18

employee or agent of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

         6.3      PAYMENT OF EXPENSES IN ADVANCE.

                  Expenses incurred in defending any action or proceeding for
which indemnification is required pursuant to Section 6.1 or for which
indemnification is permitted pursuant to Section 6.2 following authorization
thereof by the Board of Directors shall be paid by the corporation in advance of
the final disposition of such action or proceeding upon receipt of an
undertaking by or on behalf of the indemnified party to repay such amount if it
shall ultimately be determined that the indemnified party is not entitled to be
indemnified as authorized in this Article VI.

         6.4      INDEMNITY NOT EXCLUSIVE.

                  The indemnification provided by this Article VI shall not be
deemed exclusive of any other rights to which those seeking indemnification may
be entitled under any Bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the certificate of
incorporation

         6.5      INSURANCE.

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

         6.6      CONFLICTS.

                  No indemnification or advance shall be made under this Article
VI, except where such indemnification or advance is mandated by law or the
order, judgment or decree of any court of competent jurisdiction, in any
circumstance where it appears:

                  (a) That it would be inconsistent with a provision of the
certificate of incorporation, these Bylaws, a resolution of the stockholders or
an agreement in effect at the time of the accrual of the alleged cause of the
action asserted in the proceeding in which the expenses were incurred or other
amounts were paid, which prohibits or otherwise limits indemnification; or

                  (b) That it would be inconsistent with any condition expressly
imposed by a court in approving a settlement.

                                   ARTICLE VII

                               RECORDS AND REPORTS

         7.1      MAINTENANCE AND INSPECTION OF RECORDS.

                  The corporation shall, either at its principal executive
offices or at such place or places as designated by the Board of Directors, keep
a record of its stockholders listing their names and addresses and the number
and class of shares held by each stockholder, a copy of these Bylaws as amended
to date, accounting books, and other records.

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

         7.2      INSPECTION BY DIRECTORS.

                  Any director shall have the right to examine the corporation's
stock ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his or her position as a director. The Court of
Chancery is hereby vested with the exclusive jurisdiction to determine whether a
director is entitled to the inspection sought. The Court may summarily order the
corporation to permit the director to inspect any and all books and records, the
stock ledger, and the stock list and to make copies or extracts therefrom. The
Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

         7.3      ANNUAL STATEMENT TO STOCKHOLDERS.

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

                                  ARTICLE VIII

                                 GENERAL MATTERS
         8.1      CHECKS.

                  From time to time, the Board of Directors shall determine by
resolution which person or persons may sign or endorse all checks, drafts, other
orders for payment of money,
<PAGE>   20

notes or other evidences of indebtedness that are issued in the name of or
payable to the corporation, and only the persons so authorized shall sign or
endorse those instruments.

         8.2      EXECUTION OF CORPORATE CONTRACTS AND INSTRUMENTS.

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

         8.3      STOCK CERTIFICATES; PARTLY PAID SHARES.

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

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

         8.4      SPECIAL DESIGNATION ON CERTIFICATES.

                  If the corporation is authorized to issue more than one class
of stock or more than one series of any class, then the powers, the
designations, the preferences, and the relative, participating, optional or
other special rights of each class of stock or series thereof and the
qualifications, limitations or restrictions of such preferences and/or rights
shall be set forth in full
<PAGE>   21

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

         8.5      LOST CERTIFICATES.

                  Except as provided in this Section 8.5, no new certificates
for shares shall be issued to replace a previously issued certificate unless the
latter is surrendered to the corporation and canceled at the same time. The
corporation may issue a new certificate of stock or uncertificated shares in the
place of any certificate previously issued by it, alleged to have been lost,
stolen or destroyed, and the corporation may require the owner of the lost,
stolen or destroyed certificate, or the owner's legal representative, to give
the corporation a bond sufficient to indemnify it against any claim that may be
made against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate or uncertificated shares.

         8.6      CONSTRUCTION; DEFINITIONS.

                  Unless the context requires otherwise, the general provisions,
rules of construction, and definitions in the Delaware General Corporation Law
shall govern the construction of these Bylaws. Without limiting the generality
of this provision, the singular number includes the plural, the plural number
includes the singular, and the term "person" includes both a corporation and a
natural person.

         8.7      DIVIDENDS.

                  The directors of the corporation, subject to any restrictions
contained in (a) the General Corporation Law of Delaware or (b) the certificate
of incorporation, may declare and pay dividends upon the shares of its capital
stock. Dividends may be paid in cash, in property, or in shares of the
corporation's capital stock.

                  The directors of the corporation may set apart out of any of
the funds of the corporation available for dividends a reserve or reserves for
any proper purpose and may abolish any such reserve. Such purposes shall include
but not be limited to equalizing dividends, repairing or maintaining any
property of the corporation, and meeting contingencies.

         8.8      FISCAL YEAR.

                  The fiscal year of the corporation shall be fixed by
resolution of the Board of Directors and may be changed by the Board of
Directors.
<PAGE>   22

         8.9      SEAL.

                  The corporation may adopt a corporate seal, which may be
altered at pleasure, and may use the same by causing it or a facsimile thereof,
to be impressed or affixed or in any other manner reproduced.

         8.10     TRANSFER OF STOCK.

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

         8.11     STOCK TRANSFER AGREEMENTS.

                  The corporation shall have power to enter into and perform any
agreement with any number of stockholders of any one or more classes of stock of
the corporation to restrict the transfer of shares of stock of the corporation
of any one or more classes owned by such stockholders in any manner not
prohibited by the General Corporation Law of Delaware.

         8.12     REGISTERED STOCKHOLDERS.

                  The corporation shall be entitled to recognize the exclusive
right of a person registered on its books as the owner of shares to receive
dividends and to vote as such owner, shall be entitled to hold liable for calls
and assessments the person registered on its books as the owner of shares, and
shall not be bound to recognize any equitable or other claim to or interest in
such share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                   ARTICLE IX

                                   AMENDMENTS

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

Shares outstanding on the last day of the immediately preceding fiscal year, or
(iii) such lesser number of Shares as is determined by the Board. The Shares may
be authorized, but unissued, or reacquired Common Stock. The number of Shares
subject to the Plan set forth in this Section 3 are subject to adjustment in
accordance with the provisions of Section 15 of the Plan.


         If an Option expires or becomes unexercisable for any reason without
having been exercised in full, or is surrendered pursuant to an Option Exchange
Program, the unpurchased Shares that were subject thereto shall, unless the Plan
has been terminated, become available for future grant under the Plan. In
addition, any Shares of Common Stock that are retained by the Company upon
exercise of an Option or Stock Purchase Right in order to satisfy the exercise
or purchase price for such Option or Stock Purchase Right or any withholding
taxes due with respect to such exercise or purchase shall be treated as not
issued and shall continue to be available under the Plan. Notwithstanding any
other provision of the Plan, Shares issued under the Plan and later repurchased
by the Company pursuant to any repurchase right that the Company may have shall
not be available for future grant under the Plan.

         4.       ADMINISTRATION OF THE PLAN.

                  (a) GENERAL. The Plan shall be administered by the Board or a
Committee, or a combination thereof, as determined by the Board. The Plan may be
administered by different administrative bodies with respect to different
classes of Participants and, if permitted by the Applicable Laws, the Board may
authorize one or more officers (who may (but need not) be Officers) to grant
Options or Stock Purchase Rights to Employees and Consultants (other than
Consultants who are Directors).

                  (b) ADMINISTRATION WITH RESPECT TO REPORTING PERSONS AND NAMED
EXECUTIVES. With respect to Options granted to Reporting Persons and Named
Executives, the Plan may (but need not) be administered so as to permit grants
of Options to Reporting Persons to qualify for the exemption set forth in Rule
16b-3 and to permit grants of Options to Named Executives to qualify as
performance-based compensation under Section 162(m) of the Code, and otherwise
so as to satisfy the Applicable Laws.

                  (c) COMMITTEE COMPOSITION. If a Committee has been appointed
pursuant to this Section 4, such Committee shall continue to serve in its
designated capacity until otherwise directed by the Board. From time to time the
Board may increase the size of any Committee and appoint additional members
thereof, remove members (with or without cause) and appoint new members in
substitution therefor, fill vacancies (however caused) and remove all members of
a Committee and thereafter directly administer the Plan, all to the extent
permitted by the
<PAGE>   6
Applicable Laws and, in the case of a Committee administering the Plan pursuant
to Section 4(b) above, to the extent permitted or required by Rule 16b-3 and
Section 162(m) of the Code.

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

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

                      (ii) to select the Employees and Consultants to whom
Options and Stock Purchase Rights or any combination thereof may from time to
time be granted;

                      (iii) to determine whether and to what extent Options and
Stock Purchase Rights or any combination thereof are granted;

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

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

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

                      (vii) to determine whether and under what circumstances an
Option may be settled in cash under Section 10(f) instead of Common Stock;

                      (viii) to reduce the exercise price of any Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option shall have declined since the date the Option was granted
and to make any other amendments or adjustments to any Option that the
Administrator determines, in its discretion and under the authority granted to
it under the Plan, to be necessary or advisable, provided however that no
amendment or adjustment to an Option that would materially and adversely affect
the rights of any Optionee shall be made without the prior written consent of
the Optionee;

                      (ix) to determine the terms and restrictions applicable to
Stock Purchase Rights and the Restricted Stock purchased by exercising such
Stock Purchase Rights;

                      (x) to initiate an Option Exchange Program;

                      (xi) to construe and interpret the terms of the Plan and
awards granted under the Plan; and
<PAGE>   7
                      (xii) in order to fulfill the purposes of the Plan and
without amending the Plan, to modify grants of Options or Stock Purchase Rights
to Participants who are foreign nationals or employed outside of the United
States in order to recognize differences in local law, tax policies or customs.

                  (e) EFFECT OF ADMINISTRATOR'S DECISION. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Participants.

         5.       ELIGIBILITY.

                  (a) RECIPIENTS OF GRANTS. Nonstatutory Stock Options and Stock
Purchase Rights may be granted to Employees and Consultants. Incentive Stock
Options may be granted only to Employees, provided however that Employees of
Affiliates shall not be eligible to receive Incentive Stock Options. An Employee
or Consultant who has been granted an Option or Stock Option Right may, if he or
she is otherwise eligible, be granted additional Options or Stock Purchase
Rights.

                  (b) TYPE OF OPTION. Each Option shall be designated in the
Option Agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option. However, notwithstanding such designations, to the extent that the
aggregate Fair Market Value of Shares with respect to which Options are
exercisable for the first time by an Optionee during any calendar year (under
all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such
excess Options shall be treated as Nonstatutory Stock Options. For purposes of
this Section 5(b), Incentive Stock Options shall be taken into account in the
order in which they were granted, and the Fair Market Value of the Shares shall
be determined as of the date of grant of such Option. In the event any Option
designated as an Incentive Stock Option fails to meet the requirements set forth
in this Plan for an Incentive Stock Option or as required to qualify as an
incentive stock option within the meaning of Code Section 422, such Option shall
not be void but instead shall be deemed a Nonstatutory Stock Option.

                  (c) NO EMPLOYMENT RIGHTS. The Plan shall not confer upon any
Participant any right with respect to continuation of employment or consulting
relationship with the Company, nor shall it interfere in any way with his or her
right or the Company's right to terminate his or her employment or consulting
relationship at any time, with or without cause.

         6.       TERM OF PLAN. The Plan shall become effective upon its
adoption by the Board. It shall continue in effect for a term of ten (10) years
unless sooner terminated under Section 16 of the Plan.

         7.       TERM OF OPTION. The term of each Option shall be the term
stated in the Option Agreement; provided however that the term shall be no more
than ten (10) years from the date of grant thereof or such shorter term as may
be provided in the Option Agreement and provided further that, in the case of an
Incentive Stock Option granted to a person who at the time of such grant is a
Ten Percent Holder, the term of such Incentive Stock Option shall be five (5)
years from the date of grant thereof or such shorter term as may be provided in
the Option Agreement.
<PAGE>   8
         8.       LIMITATION ON GRANTS TO EMPLOYEES. Subject to adjustment as
provided in Section 13 below, the maximum number of Shares which may be subject
to Options and Stock Purchase Rights granted to any one Employee under this Plan
for any fiscal year of the Company shall be 2,000,000.

         9.       OPTION EXERCISE PRICE AND CONSIDERATION.

                  (a) EXERCISE PRICE. The per Share exercise price for the
Shares to be issued pursuant to exercise of an Option shall be such price as is
determined by the Administrator and set forth in the Option Agreement, but shall
be subject to the following:

                      (i) In the case of an Incentive Stock Option

                          (A) granted to an Employee who at the time of grant is
a Ten Percent Holder, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of grant; or

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

                      (ii) In the case of a Nonstatutory Stock Option

                          (A) granted prior to the date, if any, on which the
Common Stock becomes a Listed Security to a person who is at the time of grant
is a Ten Percent Holder, the per Share exercise price shall be no less than 110%
of the Fair Market Value per Share on the date of grant if required by the
Applicable Laws and, if not so required, shall be such price as is determined by
the Administrator;

                          (B) granted to a person who, at the time of the grant
of such Option, is a Named Executive of the Company, the per share Exercise
Price shall be no less than 100% of the Fair Market Value on the date of grant
if such Option is intended to qualify as performance-based compensation under
Section 162(m) of the Code; or

                          (C) granted prior to the date, if any, on which the
Common Stock becomes a Listed Security to any person other than a Named
Executive or a Ten Percent Holder, the per Share exercise price shall be no less
than 85% of the Fair Market Value per Share on the date of grant if required by
Applicable Law and, if not so required, shall be such price as is determined by
the Administrator.

                      (iii) Notwithstanding the foregoing, Options may be
granted with a per Share exercise price other than as required above pursuant to
a Corporate Transaction.

                  (b) PERMISSIBLE CONSIDERATION. The consideration to be paid
for the Shares to be issued upon exercise of an Option, including the method of
payment, shall be determined by the Administrator (and, in the case of an
Incentive Stock Option, shall be determined at the time of grant) and may
consist entirely of (1) cash; (2) check; (3) delivery of Optionee's
<PAGE>   9
promissory note with such recourse, interest, security and redemption provisions
as the Administrator determines to be appropriate; (4) cancellation of
indebtedness; (5) surrender of other Shares that (x) in the case of Shares
acquired upon exercise of an Option either have been owned by the Optionee for
more than six months on the date of surrender (or such other period as may be
required to avoid a charge to the Company's earnings) or were not acquired,
directly or indirectly, from the Company, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which the Option is exercised; (6) authorization by the Optionee for the Company
to retain from the total number of Shares as to which the Option is exercised
that number of Shares having a Fair Market Value on the date of exercise equal
to the exercise price for the total number of Shares as to which the Option is
exercised; (7) delivery of a properly executed exercise notice together with
such other documentation as the Administrator and the broker, if applicable,
shall require to effect exercise of the Option and prompt delivery to the
Company of the sale or loan proceeds required to pay the exercise price and any
applicable withholding taxes; (8) any combination of the foregoing methods of
payment; or (9) such other consideration and method of payment for the issuance
of Shares to the extent permitted under the Applicable Laws. In making its
determination as to the type of consideration to accept, the Administrator shall
consider whether acceptance of such consideration may be reasonably expected to
benefit the Company and the Administrator may refuse to accept a particular form
of consideration at the time of any Option exercise if, in its sole discretion,
acceptance of such form of consideration is not in the best interests of the
Company at such time.

         10.      EXERCISE OF OPTION.

                  (a) VESTING. Any Option granted hereunder shall be exercisable
at such times and under such conditions as determined by the Administrator,
consistent with the terms of the Plan, and reflected in the Option Agreement,
including vesting requirements and/or performance criteria with respect to the
Company and/or the Optionee; provided however that, if required by the
Applicable Laws, any Option granted prior to the date, if any, upon which the
Common Stock becomes a Listed Security shall become exercisable at a rate of at
least 20% per year over five years from the date the Option is granted. In the
event that any of the Shares issued upon exercise of an Option (which exercise
occurs prior to the date, if any, upon which the Common Stock becomes a Listed
Security) should be subject to a right of repurchase in the Company's favor,
such repurchase right shall, if required by the Applicable Laws, lapse at the
rate of at least 20% per year over five years from the date the Option is
granted. Notwithstanding the above, in the case of an Option granted to an
officer (including but not limited to Officers), Director or Consultant, the
Option may become exercisable, or a repurchase right, if any, in favor of the
Company shall lapse, at any time or during any period established by the
Administrator. The Administrator shall have the discretion to determine whether
and to what extent the vesting of Options shall be tolled during any unpaid
leave of absence; provided however that in the absence of such determination,
vesting of Options shall be tolled during any such leave.

                  (b) PROCEDURE FOR EXERCISE. An Option may not be exercised for
a fraction of a Share. An Option shall be deemed exercised when written notice
of such exercise has been given to the Company in accordance with the terms of
the Option by the person entitled to exercise the Option and the Company has
received full payment for the Shares with respect to
<PAGE>   10
which the Option is exercised. Full payment may, as authorized by the
Administrator, consist of any consideration and method of payment allowable
under Section 9(b) of the Plan. Exercise of an Option in any manner shall result
in a decrease in the number of Shares that thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

                  (c) RIGHTS AS A SHAREHOLDER. Until the issuance (as evidenced
by the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company) of the stock certificate evidencing such Shares,
no right to vote or receive dividends or any other rights as a shareholder shall
exist with respect to the Optioned Stock, notwithstanding the exercise of the
Option. The Company shall issue (or cause to be issued) such stock certificate
promptly upon exercise of the Option. No adjustment will be made for a dividend
or other right for which the record date is prior to the date the stock
certificate is issued, except as provided in Section 15 of the Plan.


                   (d) TERMINATION OF CONTINUOUS SERVICE. In the event of
termination of an Optionee's Continuous Service, such Optionee's right to
exercise the Option shall cease and the Option shall forthwith become void and
cease to have effect, except as set forth specifically in the Option Agreement.
Notwithstanding the foregoing, if required by the Applicable Laws, any Option
granted prior to the date, if any, upon which the Common Stock becomes a Listed
Security shall be exercisable by the Optionee for a period of time following the
termination of the Optionee's Continuous Service as follows:


                       (i) In the event of termination of Continuous Service for
reasons other than the Optionee's disability or death, the Option shall be
exercisable by the Optionee following such termination for a period of not less
than thirty (30) days, as is determined by the Administrator (with such
determination in the case of an Incentive Stock Option being made at the time of
grant of the Option), after the date of such termination of Continuous Service
(but in no event later than the date of expiration of the term of such Option as
set forth in the Option Agreement), to the extent that the Optionee was entitled
to exercise it at the date of such termination. If an Option Agreement provides
that an Incentive Stock Option may be exercised more than three (3) months after
the termination of the Optionee's Continuous Service, to the extent that such
Optionee fails to exercise such Option within three (3) months of the date of
such termination, such Option thereafter shall be treated as a Nonstatutory
Stock Option. To the extent that the Optionee was not entitled to exercise the
Option at the date of such termination, or if the Optionee does not exercise the
Option to the extent so entitled within the time specified above, the Option
shall terminate and the Optioned Stock underlying the unexercised portion of the
Option shall revert to the Plan.

                       (ii) In the event of termination of Continuous Service as
a result of Optionee's disability, such Optionee may, but only within six (6)
months (or such longer period of time as is determined by the Administrator,
with such determination in the case of an Incentive Stock Option made at the
time of grant of the Option) from the date of such termination (but in no event
later than the date of expiration of the term of such Option as set forth in the
Option Agreement), exercise the Option to the extent he or she was entitled to
<PAGE>   11
exercise it at the date of such termination. To the extent that the Optionee was
not entitled to exercise the Option at the date of termination, or if the
Optionee does not exercise the Option to the extent so entitled within the time
specified herein, the Option shall terminate and the Optioned Stock underlying
the unexercised portion of the Option shall revert to the Plan.

                       (iii) In the event of the death of an Optionee prior to
termination of his or her Continuous Service, the Option may be exercised at any
time within six (6) months (or such longer period of time as is determined by
the Administrator, with such determination in the case of an Incentive Stock
Option being made at the time of grant of the Option) following the date of
death (but in no event later than the expiration date of the term of such Option
as set forth in the Option Agreement) by such Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent of the right to exercise that had accrued at the date of
death or, if earlier, the date of termination of the Optionee's Continuous
Service. To the extent that the Optionee was not entitled to exercise the Option
at the date of death or termination, as the case may be, or if the Optionee does
not exercise such Option to the extent so entitled within the time specified
above, the Option shall terminate and the Optioned Stock underlying the
unexercised portion of the Option shall revert to the Plan.

                  (e) EXTENSION OF EXERCISE PERIOD. The Administrator shall have
full power and authority to extend the period of time for which an Option is to
remain exercisable following termination of an Optionee's Continuous Service
from the periods set forth in Sections 10(b), 10(c) and 10(d) above or in the
Option Agreement to such greater time as the Board shall deem appropriate,
provided that in no event shall such Option be exercisable later than the date
of expiration of the term of such Option as set forth in the Option Agreement.

                  (f) BUY-OUT PROVISIONS. The Administrator may at any time
offer to buy out for a payment in cash or Shares an Option previously granted
under the Plan based on such terms and conditions as the Administrator shall
establish and communicate to the Optionee at the time such offer is made.

         11.      STOCK PURCHASE RIGHTS.

                  (a) RIGHTS TO PURCHASE. Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing of the terms, conditions and restrictions related
to the offer, including the number of Shares that such person shall be entitled
to purchase, the consideration to be paid, and the time within which such person
must accept such offer, which shall in no event exceed 30 days from the date
upon which the Administrator made the determination to grant the Stock Purchase
Right. In the case of a Stock Purchase Right granted prior to the date, if any,
on which the Common Stock becomes a Listed Security and if required by the
Applicable Laws at such time, the purchase price of Shares subject to such Stock
Purchase Rights shall not be less than 85% of the Fair Market Value of the
Shares as of the date of the offer, or, in the case of a Ten Percent Holder, the
price shall not be less than 100% of the Fair Market Value of the Shares as of
the date of the offer. The offer to purchase Shares subject to
<PAGE>   12
Stock Purchase Rights shall be accepted by execution of a Restricted Stock
Purchase Agreement in the form determined by the Administrator.

                  (b) REPURCHASE OPTION. Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company an
irrevocable, exclusive option (the "Repurchase Option") exercisable upon the
termination of the purchaser's Continuous Service. The purchase price for Shares
repurchased pursuant to the Restricted Stock Purchase Agreement shall be the
original purchase price paid by the purchaser and may be paid by cash, check or
cancellation of any indebtedness of the purchaser to the Company, at the
Company's option. The Repurchase Option shall lapse at such rate as the
Administrator may determine; provided however that with respect to a Stock
Purchase Right granted prior to the date, if any, on which the Common Stock
becomes a Listed Security to a purchaser who is not an officer (including an
Officer), Director or Consultant of the Company or of any Parent or Subsidiary
of the Company, such Repurchase Option shall lapse at a minimum rate of 20% of
the Shares subject to the Stock Purchase Right if required by the Applicable
Laws.

                  (c) OTHER PROVISIONS. The Restricted Stock Purchase Agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion. In
addition, the provisions of Restricted Stock Purchase Agreements need not be the
same with respect to each purchaser.

                  (d) RIGHTS AS A SHAREHOLDER. Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 15
of the Plan.

         12.      TAXES.

                  (a) As a condition of the exercise of an Option or Stock
Purchase Right granted under the Plan, the Participant (or in the case of the
Participant's death, the person exercising the Option or Stock Purchase Right)
shall make such arrangements as the Administrator may require for the
satisfaction of any applicable federal, state, local or foreign withholding tax
obligations that may arise in connection with the exercise of Option or Stock
Purchase Right and the issuance of Shares. The Company shall not be required to
issue any Shares under the Plan until such obligations are satisfied.

                  (b) In the case of an Employee and in the absence of any other
arrangement, the Employee shall be deemed to have directed the Company to
withhold or collect from his or her compensation an amount sufficient to satisfy
such tax obligations from the next payroll payment otherwise payable after the
date of an exercise of the Option or Stock Purchase Right.

                  (c) This Section 12(c) shall apply only after the date, if
any, upon which the Common Stock becomes a Listed Security. In the case of
Participant other than an Employee (or in the case of an Employee where the next
payroll payment is not sufficient to satisfy such tax
<PAGE>   13
obligations, with respect to any remaining tax obligations), in the absence of
any other arrangement and to the extent permitted under the Applicable Laws, the
Participant shall be deemed to have elected to have the Company withhold from
the Shares to be issued upon exercise of the Option or Stock Purchase Right that
number of Shares having a Fair Market Value determined as of the applicable Tax
Date (as defined below) equal to the amount required to be withheld. For
purposes of this Section 12, the Fair Market Value of the Shares to be withheld
shall be determined on the date that the amount of tax to be withheld is to be
determined under the Applicable Laws (the "Tax Date").

                  (d) At the discretion of the Administrator, a Participant may
satisfy his or her tax withholding obligations arising in connection with an
Option by one or some combination of the following methods: (i) by cash payment;
(ii) by payroll deduction out of the Optionee's current compensation; or (iii)
if permitted by the Administrator, in its discretion, a Participant may satisfy
his or her tax withholding obligations upon exercise of an Option or Stock
Purchase Right by surrendering to the Company Shares that (A) in the case of
Shares previously acquired from the Company, have been owned by the Participant
for more than six (6) months on the date of surrender, and (B) have a Fair
Market Value determined as of the applicable Tax Date equal to the amount
required to be withheld.

                  (e) Any election or deemed election by a Participant to have
Shares withheld to satisfy tax withholding obligations under Section 12(c) or
(d) above shall be irrevocable as to the particular Shares as to which the
election is made and shall be subject to the consent or disapproval of the
Administrator. Any election by a Participant under Section 12(d) above must be
made on or prior to the applicable Tax Date.

                  (f) In the event an election to have Shares withheld is made
by a Participant and the Tax Date is deferred under Section 83 of the Code
because no election is filed under Section 83(b) of the Code, the Participant
shall receive the full number of Shares with respect to which the Option or
Stock Purchase Right is exercised but such Participant shall be unconditionally
obligated to tender back to the Company the proper number of Shares on the Tax
Date.

         13.      NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS.
Options and Stock Purchase Rights may not be transferred or disposed of in any
manner other than by will or by the laws of descent or distribution or pursuant
to a domestic relations order (as defined by the Code or the rules thereunder);
provided that, after the date, if any, upon which the Common Stock becomes a
Listed Security, the Administrator may in its discretion grant transferable
Nonstatutory Stock Options pursuant to Option Agreements specifying (i) the
manner in which such Nonstatutory Stock Options are transferable and (ii) that
any such transfer shall be subject to the Applicable Laws. The designation of a
beneficiary by an Optionee will not constitute a transfer. An Option or Stock
Purchase Right may be exercised, during the lifetime of the holder of Option or
Stock Purchase Right, only by such holder or a transferee permitted by this
Section 13.
<PAGE>   14
         14.      TIME OF GRANTING OPTIONS AND STOCK PURCHASE RIGHTS. The date
of grant of an Option or Stock Purchase Right shall, for all purposes, be the
date on which the Administrator makes the determination granting such Option or
Stock Purchase Right, or such later date as is determined by the Administrator;
provided however that in the case of an Incentive Stock Option, the grant date
shall be the later of the date on which the Administrator makes the
determination granting such Incentive Stock Option or the date of commencement
of the Optionee's employment relationship with the Company. Notice of the
determination shall be given to each Employee or Consultant to whom an Option or
Stock Purchase Right is so granted within a reasonable time after the date of
such grant.

         15.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, CORPORATE
TRANSACTIONS AND CERTAIN OTHER TRANSACTIONS.

                  (a) CHANGES IN CAPITALIZATION. Subject to any required action
by the shareholders of the Company, the number of shares of Common Stock covered
by each outstanding Option or Stock Purchase Right, the number of Shares set
forth in Sections 3 and 8 above, and the number of shares of Common Stock that
have been authorized for issuance under the Plan but as to which no Options or
Stock Purchase Rights have yet been granted or that have been returned to the
Plan upon cancellation or expiration of an Option or Stock Purchase Right, as
well as the price per Share of Common Stock covered by each such outstanding
Option or Stock Purchase Right, shall be proportionately adjusted for any
increase or decrease in the number of issued Shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination,
recapitalization or reclassification of the Common Stock (including any change
in the number of Shares of Common Stock effected in connection with a change of
domicile of the Company), or any other increase or decrease in the number of
issued Shares of Common Stock effected without receipt of consideration by the
Company; provided however that conversion of any convertible securities of the
Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Administrator, whose
determination in that respect shall be final, binding and conclusive. Except as
expressly provided herein, no issuance by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of Shares of Common Stock subject to an Option or Stock Purchase
Right.


                  (b) DISSOLUTION OR LIQUIDATION. In the event of the
dissolution or liquidation of the Company, the Administrator shall notify the
Optionee at least fifteen (15) days prior to such proposed action. To the extent
it has not previously been exercised, each outstanding Option or Stock Purchase
Right shall terminate immediately prior to the consummation of such action,
unless otherwise provided by the Administrator.


                  (c) CORPORATE TRANSACTIONS; CHANGE OF CONTROL. In the event of
a Corporate Transaction, including a Change of Control, each outstanding Option
and Stock Purchase Right shall be assumed or an equivalent option or right shall
be substituted by the successor corporation or a Parent or Subsidiary of such
successor corporation (such entity, the "Successor Corporation"), unless the
Successor Corporation does not agree to such assumption
<PAGE>   15

or substitution, in which case such Options and Stock Purchase Rights shall
terminate upon consummation of the transaction.


                  For purposes of this Section 15(c), an Option or a Stock
Purchase Right shall be considered assumed, without limitation, if, at the time
of issuance of the stock or other consideration upon a Corporate Transaction or
a Change of Control, as the case may be, each holder of an Option or Stock
Purchase Right would be entitled to receive upon exercise of the Option or Stock
Purchase Right the same number and kind of shares of stock or the same amount of
property, cash or securities as such holder would have been entitled to receive
upon the occurrence of the transaction if the holder had been, immediately prior
to such transaction, the holder of the number of Shares of Common Stock covered
by the Option or the Stock Purchase Right at such time (after giving effect to
any adjustments in the number of Shares covered by the Option or Stock Purchase
Right as provided for in this Section 15); provided however that if the
consideration received in the transaction is not solely common stock of the
Successor Corporation, the Administrator may, with the consent of the Successor
Corporation, provide for the consideration to be received upon exercise of the
Option or Stock Purchase Right to be solely common stock of the Successor
Corporation equal to the Fair Market Value of the per Share consideration
received by holders of Common Stock in the transaction.

                  (d) CERTAIN DISTRIBUTIONS. In the event of any distribution to
the Company's shareholders of securities of any other entity or other assets
(other than dividends payable in cash or stock of the Company) without receipt
of consideration by the Company, the Administrator may, in its discretion,
appropriately adjust the price per Share of Common Stock covered by each
outstanding Option or Stock Purchase Right to reflect the effect of such
distribution.

         16.      AMENDMENT AND TERMINATION OF THE PLAN.

                  (a) AMENDMENT AND TERMINATION. The Board may at any time
amend, alter, suspend, discontinue or terminate the Plan. To the extent
necessary and desirable to comply with the Applicable Laws, the Company shall
obtain shareholder approval of any Plan amendment in such a manner and to such
as degree as required.

                  (b) EFFECT OF AMENDMENT OR TERMINATION. Except as provided in
Section 15, no amendment, suspension or termination of the Plan shall materially
and adversely affect Options already granted and such Options shall remain in
full force and effect as if the Plan had not been amended, suspended or
terminated, unless mutually agreed otherwise between the Optionee and the
Company, which agreement must be in writing and signed by such Optionee and the
Company. Except as provided in Section 15, no amendment, suspension or
termination of the Plan shall materially and adversely affect Stock Purchase
Rights already granted, or the
<PAGE>   16
holder of Restricted Stock acquired pursuant to a Stock Purchase Right, unless
mutually agreed otherwise between the holder of the Stock Purchase Right and the
Company, which agreement must be in writing and signed by such holder and the
Company.

         17. CONDITIONS UPON ISSUANCE OF SHARES. Notwithstanding any other
provision of the Plan or any agreement entered into by the Company pursuant to
the Plan, the Company shall not be obligated, and shall have no liability for
failure, to issue or deliver any Shares under the Plan unless such issuance or
delivery would comply with the Applicable Laws, with such compliance determined
by the Company in consultation with its legal counsel.

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

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

         19. AGREEMENTS. Options and Stock Purchase Rights shall be evidenced by
Option Agreements and Restricted Stock Purchase Agreements, respectively, in
such form(s) as the Administrator shall from time to time approve.

         20. SHAREHOLDER APPROVAL. If required by the Applicable Laws,
continuance of the Plan shall be subject to approval by the shareholders of the
Company within twelve (12) months before or after the date the Plan is adopted.
Such shareholder approval shall be obtained in the manner and to the degree
required under the Applicable Laws.

         21. INFORMATION AND DOCUMENTS TO OPTIONEES AND PURCHASERS. Prior to the
date, if any, upon which the Common Stock becomes a Listed Security and if
required by the Applicable Laws, the Company shall provide financial statements
at least annually to each Optionee and to each individual who acquired Shares
pursuant to the Plan, during the period such Optionee or purchaser has one or
more Options or Stock Purchase Rights outstanding, and in the case of an
individual who acquired Shares pursuant to the Plan, during the period such
individual owns such Shares. The Company shall not be required to provide such
information if the issuance of Options or Stock Purchase Rights under the Plan
is limited to key employees whose duties in connection with the Company assure
their access to equivalent information.

                                 1997 STOCK PLAN

                             STOCK OPTION AGREEMENT


         1. GRANT OF OPTION. Persistence Software, Inc., a California
corporation (the "Company"), hereby grants to <<Optionee>> ("Optionee"), an
option (the "Option") to purchase a total number of shares of Common Stock (the
"Shares") set forth in the Notice of Stock Option Grant, at the exercise price
per share set forth in the Notice of Stock Option Grant (the "Exercise Price")
subject to the terms, definitions and provisions of the Persistence Software,
Inc. 1997 Stock Plan (the "Plan") adopted by the Company, which is incorporated
herein by reference. Unless otherwise defined herein, the terms defined in the
Plan shall have the same defined meanings in this Option.

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

         2. EXERCISE OF OPTION. This Option shall be exercisable during its Term
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant and with the provisions of Section 9 of the Plan as follows:

                  (a)      RIGHT TO EXERCISE.

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

                           (ii) In the event of Optionee's death, disability or
other termination of employment, the exercisability of the Option is governed by
Sections 5, 6 and 7 below, subject to the limitation contained in Section
2(a)(i).

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

                  (b) METHOD OF EXERCISE. This Option shall be exercisable by
execution and delivery of the Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit A (the "Exercise Agreement") or of any
other form of written notice approved for such purpose by the Company which
shall state the election to exercise the Option, the number of Shares in respect
of which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such shares of
Common Stock as may be required by the Company pursuant to the provisions of the
Plan. Such written notice shall be signed by Optionee and shall be delivered in
person or by certified mail to the Secretary of the Company. The written notice
shall be accompanied by payment of the Exercise Price. This Option shall be
deemed to be exercised upon receipt by the Company of such written notice
accompanied by the Exercise Price.


<PAGE>   20
                  No Shares will be issued pursuant to the exercise of an Option
unless such issuance and such exercise shall comply with all relevant provisions
of applicable law and the requirements of any stock exchange upon which the
Shares may then be listed. Assuming such compliance, for income tax purposes the
Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

         3. METHOD OF PAYMENT. Payment of the Exercise Price shall be by any of
the following, or a combination thereof, at the election of Optionee:

                  (a)      cash;

                  (b)      check;

                  (c) surrender of other shares of Common Stock of the Company
which (i) in the case of Shares acquired pursuant to the exercise of a Company
option, have been owned by Optionee for more than six (6) months on the date of
surrender, and (ii) have a fair market value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

                  (d) if there is a public market for the Shares and they are
 registered under the Securities Act, delivery of a properly executed exercise
 notice together with irrevocable instructions to a
broker to deliver promptly to the Company the amount of sale or loan proceeds
required to pay the exercise price.

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

         5. TERMINATION OF RELATIONSHIP. In the event of termination of
Optionee's Continuous Status as an Employee or Consultant, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
Date"), exercise this Option during the Termination Period set forth in the
Notice of Stock Option Grant. To the extent that Optionee was not entitled to
exercise this Option at such Termination Date, or if Optionee does not exercise
this Option within the Termination Period, the Option shall terminate.

         6.       DISABILITY OF OPTIONEE.

                  (a) Notwithstanding the provisions of Section 5 above, in the
event of termination of Continuous Status as an Employee or Consultant as a
result of Optionee's total and permanent disability (as defined in Section
22(e)(3) of the Code), Optionee may, but only within twelve (12) months from the
Termination Date (but in no event later than the Expiration Date set forth in
the Notice of Stock Option Grant), exercise this Option to the


                                      -2-
<PAGE>   21
extent Optionee was entitled to exercise it as of such Termination Date. To the
extent that Optionee was not entitled to exercise the Option as of the
Termination Date, or if Optionee does not exercise such Option (to the extent so
entitled) within the time specified in this Section 6(a), the Option shall
terminate.

                  (b) Notwithstanding the provisions of Section 5 above, in the
event of termination of Optionee's consulting relationship or Continuous Status
as an Employee as a result of disability not constituting a total and permanent
disability (as set forth in Section 22(e)(3) of the Code), Optionee may, but
only within six (6) months from the Termination Date (but in no event later than
the Expiration Date set forth in the Notice of Stock Option Grant), exercise the
Option to the extent Optionee was entitled to exercise it as of such Termination
Date; provided, however, that if this is an Incentive Stock Option and Optionee
fails to exercise this Incentive Stock Option within three (3) months from the
Termination Date, this Option will cease to qualify as an Incentive Stock Option
(as defined in Section 422 of the Code) and Optionee will be treated for federal
income tax purposes as having received ordinary income at the time of such
exercise in an amount generally measured by the difference between the Exercise
Price for the Shares and the fair market value of the Shares on the date of
exercise. To the extent that Optionee was not entitled to exercise the Option at
the Termination Date, or if Optionee does not exercise such Option to the extent
so entitled within the time specified in this Section 6(b), the Option shall
terminate.

         7. DEATH OF OPTIONEE. In the event of the death of Optionee (a) during
the Term of this Option and while an Employee or Consultant of the Company and
having been in Continuous Status as an Employee or Consultant since the date of
grant of the Option, or (b) within thirty (30) days after Optionee's Termination
Date, the Option may be exercised at any time within six (6) months following
the date of death (but in no event later than the Expiration Date set forth in
the Notice of Stock Option Grant), by Optionee's estate or by a person who
acquired the right to exercise the Option by bequest or inheritance, but only to
the extent of the right to exercise that had accrued at the Termination Date.

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

         9. TERM OF OPTION. This Option may be exercised only within the Term
set forth in the Notice of Stock Option Grant, subject to the limitations set
forth in Section 7 of the Plan.

         10. TAX CONSEQUENCES. Set forth below is a brief summary as of the date
of this Option of certain of the federal tax consequences of exercise of this
Option and disposition of the Shares under the laws in effect as of the Date of
Grant. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS
ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

                                      -3-
<PAGE>   22
                  (a) EXERCISE OF INCENTIVE STOCK OPTION. If this Option
qualifies as an Incentive Stock Option, there will be no regular federal income
tax liability upon the exercise of the Option, although the excess, if any, of
the fair market value of the Shares on the date of exercise over the Exercise
Price will be treated as an adjustment to the alternative minimum tax for
federal tax purposes and may subject Optionee to the alternative minimum tax in
the year of exercise.

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

                  (c) DISPOSITION OF SHARES. In the case of a Nonstatutory Stock
Option, if Shares are held for at least one year, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. In the case of an Incentive Stock Option, if Shares
transferred pursuant to the Option are held for at least one year after exercise
and are disposed of at least two years after the Date of Grant, any gain
realized on disposition of the Shares will also be treated as long-term capital
gain for federal income tax purposes. If Shares purchased under an Incentive
Stock Option are disposed of within such one-year period or within two years
after the Date of Grant, any gain realized on such disposition will be treated
as compensation income (taxable at ordinary income rates) to the extent of the
difference between the Exercise Price and the lesser of (i) the fair market
value of the Shares on the date of exercise, or (ii) the sale price of the
Shares.

                  (d) NOTICE OF DISQUALIFYING DISPOSITION OF INCENTIVE STOCK
OPTION SHARES. If the Option granted to Optionee herein is an Incentive Stock
Option, and if Optionee sells or otherwise disposes of any of the Shares
acquired pursuant to the Incentive Stock Option on or before the later of (i)
the date two years after the Date of Grant, or (ii) the date one year after the
date of exercise, Optionee shall immediately notify the Company in writing of
such disposition. Optionee acknowledges and agrees that he or she may be subject
to income tax withholding by the Company on the compensation income recognized
by Optionee from the early disposition by payment in cash or out of the current
earnings paid to Optionee.

         11. WITHHOLDING TAX OBLIGATIONS. Optionee understands that, upon
exercising a Nonstatutory Stock Option, he or she will recognize income for tax
purposes in an amount equal to the excess of the then fair market value of the
Shares over the Exercise Price. However, the timing of this income recognition
may be deferred for up to six months if Optionee is subject to Section 16 of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). If Optionee is
an employee, the Company will be required to withhold from Optionee's
compensation, or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income.
Additionally,

                                      -4-
<PAGE>   23
Optionee may at some point be required to satisfy tax withholding obligations
with respect to the disqualifying disposition of an Incentive Stock Option.
Optionee shall satisfy his or her tax withholding obligation arising upon the
exercise of this Option by one or some combination of the following methods: (a)
by cash payment, (b) out of Optionee's current compensation, (c) if permitted by
the Administrator, in its discretion, by surrendering to the Company Shares
which (i) in the case of Shares previously acquired from the Company, have been
owned by Optionee for more than six months on the date of surrender, and (ii)
have a fair market value on the date of surrender equal to or greater than
Optionee's marginal tax rate times the ordinary income recognized, or (d) by
electing to have the Company withhold from the Shares to be issued upon exercise
of the Option that number of Shares having a fair market value equal to the
amount required to be withheld. For this purpose, the fair market value of the
Shares to be withheld shall be determined on the date that the amount of tax to
be withheld is to be determined (the "Tax Date").

         If Optionee is subject to Section 16 of the Exchange Act (an
"Insider"), any surrender of previously owned Shares to satisfy tax withholding
obligations arising upon exercise of this Option must comply with the applicable
provisions of Rule 16b-3 promulgated under the Exchange Act ("Rule 16b-3").

         All elections by Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

                  (a) the election must be made on or prior to the applicable
Tax Date;

                  (b) once made, the election shall be irrevocable as to the
particular Shares of the Option as to which the election is made; and

                  (c) all elections shall be subject to the consent or
disapproval of the Administrator.

         12. MARKET STANDOFF AGREEMENT. In connection with the initial public
offering of the Company's securities and upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities,
Optionee hereby agrees not to sell, make any short sale of, loan, grant any
option for the purchase of, or otherwise dispose of any Shares (other than those
included in the registration) without the prior written consent of the Company
or such underwriters, as the case may be, for such period of time (not to exceed
180 days) from the effective date of such registration as may be requested by
the Company or such managing underwriters and to execute an agreement reflecting
the foregoing as may be requested by the underwriters at the time of the public
offering.

                           PERSISTENCE SOFTWARE, INC.

                                 1997 STOCK PLAN

             EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT

         This Agreement ("Agreement") is made as of ______________, by and
between Persistence Software, Inc., a California corporation (the "Company"),
and <<Optionee>> ("Purchaser"). To the extent any capitalized terms used in this
Agreement are not defined, they shall have the meaning ascribed to them in the
1997 Stock Plan.

         1. EXERCISE OF OPTION. Subject to the terms and conditions hereof,
Purchaser hereby elects to exercise his or her option to purchase ______________
shares of the Common Stock (the "Shares") of the Company under and pursuant to
the Company's 1997 Stock Plan (the "Plan") and the Stock Option Agreement dated
_______________, (the "Option Agreement"). The purchase price for the Shares
shall be $<<ExercisePrice>> per Share for a total purchase price of
$_________________. The term "Shares" refers to the purchased Shares and all
securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

         2. TIME AND PLACE OF EXERCISE. The purchase and sale of the Shares
under this Agreement shall occur at the principal office of the Company
simultaneously with the execution and delivery of this Agreement in accordance
with the provisions of Section 2(b) of the Option Agreement. On such date, the
Company will deliver to Purchaser a certificate representing the Shares to be
purchased by Purchaser (which shall be issued in Purchaser's name) against
payment of the exercise price therefor by Purchaser by (a) check made payable to
the Company, (b) cancellation of indebtedness of the Company to Purchaser, (c)
delivery of shares of the Common Stock of the Company in accordance with Section
3 of the Option Agreement, or (d) by a combination of the foregoing.

         3. LIMITATIONS ON TRANSFER. In addition to any other limitation on
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares except in compliance with the
provisions below and applicable securities laws.

                  (a) RIGHT OF FIRST REFUSAL. Before any Shares held by
Purchaser or any transferee of Purchaser (either being sometimes referred to
herein as the "Holder") may be sold or otherwise transferred (including transfer
by gift or operation of law), the Company or its assignee(s) shall have a right
of first refusal to purchase the Shares on the terms and conditions set forth in
this Section 3(a) (the "Right of First Refusal").


<PAGE>   26
                           (i) NOTICE OF PROPOSED TRANSFER. The Holder of the
Shares shall deliver to the Company a written notice (the "Notice") stating: (i)
the Holder's bona fide intention to sell or otherwise transfer such Shares; (ii)
the name of each proposed purchaser or other transferee ("Proposed Transferee");
(iii) the number of Shares to be transferred to each Proposed Transferee; and
(iv) the terms and conditions of each proposed sale or transfer. The Holder
shall offer the Shares at the same price (the "Offered Price") and upon the same
terms (or terms as similar as reasonably possible) to the Company or its
assignee(s).

                           (ii) EXERCISE OF RIGHT OF FIRST REFUSAL. At any time
within thirty (30) days after receipt of the Notice, the Company and/or its
assignee(s) may, by giving written notice to the Holder, elect to purchase all,
but not less than all, of the Shares proposed to be transferred to any one or
more of the Proposed Transferees, at the purchase price determined in accordance
with subsection (iii) below.

                           (iii) PURCHASE PRICE. The purchase price ("Purchase
Price") for the Shares purchased by the Company or its assignee(s) under this
Section 3(a) shall be the Offered Price. If the Offered Price includes
consideration other than cash, the cash equivalent value of the non-cash
consideration shall be determined by the Board of Directors of the Company in
good faith.

                           (iv) PAYMENT. Payment of the Purchase Price shall be
made, at the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

                           (v) HOLDER'S RIGHT TO TRANSFER. If all of the Shares
proposed in the Notice to be transferred to a given Proposed Transferee are not
purchased by the Company and/or its assignee(s) as provided in this Section
3(a), then the Holder may sell or otherwise transfer such Shares to that
Proposed Transferee at the Offered Price or at a higher price, provided that
such sale or other transfer is consummated within 60 days after the date of the
Notice and provided further that any such sale or other transfer is effected in
accordance with any applicable securities laws and the Proposed Transferee
agrees in writing that the provisions of this Section 3 shall continue to apply
to the Shares in the hands of such Proposed Transferee. If the Shares described
in the Notice are not transferred to the Proposed Transferee within such period,
or if the Holder proposes to change the price or other terms to make them more
favorable to the Proposed Transferee, a new Notice shall be given to the
Company, and the Company and/or its assignees shall again be offered the Right
of First Refusal before any Shares held by the Holder may be sold or otherwise
transferred.

                           (vi) EXCEPTION FOR CERTAIN FAMILY TRANSFERS. Anything
to the contrary contained in this Section 3(a) notwithstanding, the transfer of
any or all of the Shares during Purchaser's lifetime or on Purchaser's death by
will or intestacy to Purchaser's Immediate Family or a trust for the benefit of
Purchaser's Immediate Family shall be exempt from the provisions of this Section
3(a). "Immediate Family" as used herein shall mean spouse, lineal descendant or
antecedent, father, mother, brother or sister. In such case, the transferee or
other recipient shall receive and hold the Shares so transferred subject to the

                                      -2-
<PAGE>   27
provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section 3.

                  (b)      INVOLUNTARY TRANSFER.

                           (i) COMPANY'S RIGHT TO PURCHASE UPON INVOLUNTARY
TRANSFER. In the event, at any time after the date of this Agreement, of any
transfer by operation of law or other involuntary transfer (including death or
divorce, but excluding a transfer to Immediate Family as set forth in Section
3(a)(vi) above) of all or a portion of the Shares by the record holder thereof,
the Company shall have an option to purchase all of the Shares transferred at
the greater of the purchase price paid by Purchaser pursuant to this Agreement
or the fair market value of the Shares on the date of transfer. Upon such a
transfer, the person acquiring the Shares shall promptly notify the Secretary of
the Company of such transfer. The right to purchase such Shares shall be
provided to the Company for a period of thirty (30) days following receipt by
the Company of written notice by the person acquiring the Shares.

                           (ii) PRICE FOR INVOLUNTARY TRANSFER. With respect to
any stock to be transferred pursuant to Section 3(b)(i), the price per Share
shall be a price set by the Board of Directors of the Company that will reflect
the current value of the stock in terms of present earnings and future prospects
of the Company. The Company shall notify Purchaser or his or her executor of the
price so determined within thirty (30) days after receipt by it of written
notice of the transfer or proposed transfer of Shares. However, if the Purchaser
does not agree with the valuation as determined by the Board of Directors of the
Company, the Purchaser shall be entitled to have the valuation determined by an
independent appraiser to be mutually agreed upon by the Company and the
Purchaser and whose fees shall be borne equally by the Company and the
Purchaser.

                  (c) ASSIGNMENT. The right of the Company to purchase any part
of the Shares may be assigned in whole or in part to any shareholder or
shareholders of the Company or other persons or organizations; provided,
however, that an assignee, other than a corporation that is the parent or a 100%
owned subsidiary of the Company, must pay the Company, upon assignment of such
right, cash equal to the difference between the original purchase price and fair
market value, if the original purchase price is less than the fair market value
of the Shares subject to the assignment.

                  (d) RESTRICTIONS BINDING ON TRANSFEREES. All transferees of
Shares or any interest therein will receive and hold such Shares or interest
subject to the provisions of this Agreement. Any sale or transfer of the
Company's Shares shall be void unless the provisions of this Agreement are
satisfied.

                  (e) TERMINATION OF RIGHTS. The right of first refusal granted
the Company by Section 3(a) above and the option to repurchase the Shares in the
event of an involuntary transfer granted the Company by Section 3(b) above shall
terminate upon the first sale of Common Stock of the Company to the general
public pursuant to a registration statement filed with and declared effective by
the Securities and Exchange Commission under the Securities Act. Upon
termination of the right of first refusal described in Section

                                      -3-
<PAGE>   28
3(a) above, a new certificate or certificates representing the Shares not
repurchased shall be issued, on request, without the legend referred to in
Section 6(a)(ii) herein and delivered to Purchaser.

         4. INVESTMENT AND TAXATION REPRESENTATIONS. In connection with the
purchase of the Shares, Purchaser represents to the Company the following:

                  (a) Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the securities.
Purchaser is purchasing these securities for investment for his or her own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act.

                  (b) Purchaser understands that the securities have not been
registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of
Purchaser's investment intent as expressed herein.

                  (c) Purchaser further acknowledges and understands that the
securities must be held indefinitely unless they are subsequently registered
under the Securities Act or an exemption from such registration is available.
Purchaser further acknowledges and understands that the Company is under no
obligation to register the securities. Purchaser understands that the
certificate(s) evidencing the securities will be imprinted with a legend which
prohibits the transfer of the securities unless they are registered or such
registration is not required in the opinion of counsel for the Company.

                  (d) Purchaser is familiar with the provisions of Rules 144 and
701, each promulgated under the Securities Act, which, in substance, permit
limited public resale of "restricted securities" acquired, directly or
indirectly, from the issuer thereof (or from an affiliate of such issuer), in a
non-public offering subject to the satisfaction of certain conditions. Rule 701
provides that if the issuer qualifies under Rule 701 at the time of issuance of
the securities, such issuance will be exempt from registration under the
Securities Act. In the event the Company becomes subject to the reporting
requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the
securities exempt under Rule 701 may be resold by the Purchaser ninety (90) days
thereafter, subject to the satisfaction of certain of the conditions specified
by Rule 144, including, among other things: (1) the sale being made through a
broker in an unsolicited "broker's transaction" or in transactions directly with
a market maker (as said term is defined under the Securities Exchange Act of
1934); and, in the case of an affiliate, (2) the availability of certain public
information about the Company, and the amount of securities being sold during
any three month period not exceeding the limitations specified in Rule 144(e),
if applicable. Notwithstanding this paragraph (d), Purchaser acknowledges and
agrees to the restrictions set forth in paragraph (f) hereof.

         In the event that the Company does not qualify under Rule 701 at the
time of purchase, then the securities may be resold by the Purchaser in certain
limited circumstances subject to the provisions of Rule 144, which requires,
among other things: (1) the availability of certain public information about the
Company; (2) the resale occurring not less than two

                                      -4-
<PAGE>   29
years after the party has purchased, and made full payment of (within the
meaning of Rule 144), the securities to be sold; and, in the case of an
affiliate, or of a non-affiliate who has held the securities less than three
years, (3) the sale being made through a broker in an unsolicited "broker's
transaction" or in transactions directly with a market maker (as said term is
defined under the Securities Exchange Act of 1934) and the amount of securities
being sold during any three month period not exceeding the specified limitations
stated therein, if applicable.

                  (e) Purchaser further understands that at the time he or she
wishes to sell the securities there may be no public market upon which to make
such a sale, and that, even if such a public market then exists, the Company may
not be satisfying the current public information requirements of Rule 144 or
701, and that, in such event, Purchaser would be precluded from selling the
securities under Rule 144 or 701 even if the two-year minimum holding period had
been satisfied.

                  (f) Purchaser further understands that in the event all of the
applicable requirements of Rule 144 or 701 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rule 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.

                  (g) Purchaser understands that Purchaser may suffer adverse
tax consequences as a result of Purchaser's purchase or disposition of the
Shares. Purchaser represents that Purchaser has consulted any tax consultants
Purchaser deems advisable in connection with the purchase or disposition of the
Shares and that Purchaser is not relying on the Company for any tax advice.

         5.       RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

                  (a) LEGENDS. The certificate or certificates representing the
Shares shall bear the following legends (as well as any legends required by
applicable state and federal corporate and securities laws):

                           (i)      THE SHARES REPRESENTED BY THIS CERTIFICATE
                                    HAVE NOT BEEN REGISTERED UNDER THE
                                    SECURITIES ACT OF 1933, AND HAVE BEEN
                                    ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW
                                    TO, OR IN CONNECTION WITH, THE SALE OR
                                    DISTRIBUTION THEREOF. NO SUCH SALE OR
                                    DISPOSITION MAY BE EFFECTED WITHOUT AN
                                    EFFECTIVE REGISTRATION STATEMENT RELATED
                                    THERETO OR AN OPINION OF COUNSEL FOR

                                      -5-
<PAGE>   30
                                    THE COMPANY THAT SUCH REGISTRATION IS NOT
                                    REQUIRED UNDER THE SECURITIES ACT OF 1933.

                           (ii)     THE SHARES REPRESENTED BY THIS CERTIFICATE
                                    MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH
                                    THE TERMS OF AN AGREEMENT BETWEEN THE
                                    COMPANY AND THE SHAREHOLDER, A COPY OF WHICH
                                    IS ON FILE WITH THE SECRETARY OF THE
                                    COMPANY.

                  (b) STOP-TRANSFER NOTICES. Purchaser agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

                  (c) REFUSAL TO TRANSFER. The Company shall not be required (i)
to transfer on its books any Shares that have been sold or otherwise transferred
in violation of any of the provisions of this Agreement or (ii) to treat as
owner of such Shares or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares shall have been so
transferred.

         6. NO EMPLOYMENT RIGHTS. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a parent or subsidiary
of the Company, to terminate Purchaser's employment, for any reason, with or
without cause.

         7. MARKET STAND-OFF AGREEMENT. In connection with the initial public
offering of the Company's securities and upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any Shares (other than those included
in the registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed 180
days) from the effective date of such registration as may be requested by the
Company or such managing underwriters and to execute an agreement reflecting the
foregoing as may be requested by the underwriters at the time of the public
offering.

         8.       MISCELLANEOUS.

                  (a) GOVERNING LAW. This Agreement and all acts and
transactions pursuant hereto and the rights and obligations of the parties
hereto shall be governed, construed and interpreted in accordance with the laws
of the State of California, without giving effect to principles of conflicts of
law.

                  (b) ENTIRE AGREEMENT; ENFORCEMENT OF RIGHTS. This Agreement
sets forth the entire agreement and understanding of the parties relating to the
subject matter herein and merges all prior discussions between them. No
modification of or amendment to this Agreement, nor any waiver of any rights
under this Agreement, shall be effective unless

                                      -6-
<PAGE>   31
in writing signed by the parties to this Agreement. The failure by either party
to enforce any rights under this Agreement shall not be construed as a waiver of
any rights of such party.

                  (c) SEVERABILITY. If one or more provisions of this Agreement
are held to be unenforceable under applicable law, the parties agree to
renegotiate such provision in good faith. In the event that the parties cannot
reach a mutually agreeable and enforceable replacement for such provision, then
(i) such provision shall be excluded from this Agreement, (ii) the balance of
the Agreement shall be interpreted as if such provision were so excluded and
(iii) the balance of the Agreement shall be enforceable in accordance with its
terms.

                  (d) CONSTRUCTION. This Agreement is the result of negotiations
between and has been reviewed by each of the parties hereto and their respective
counsel, if any; accordingly, this Agreement shall be deemed to be the product
of all of the parties hereto, and no ambiguity shall be construed in favor of or
against any one of the parties hereto.

                  (e) NOTICES. Any notice required or permitted by this
Agreement shall be in writing and shall be deemed sufficient when delivered
personally or sent by telegram or fax or forty-eight (48) hours after being
deposited in the U.S. mail, as certified or registered mail, with postage
prepaid, and addressed to the party to be notified at such party's address as
set forth below or as subsequently modified by written notice.

                  (f) COUNTERPARTS. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument.

                  (g) SUCCESSORS AND ASSIGNS. The rights and benefits of this
Agreement shall inure to the benefit of, and be enforceable by the Company's
successors and assigns. The rights and obligations of Purchaser under this
Agreement may only be assigned with the prior written consent of the Company.

                  (h) CALIFORNIA CORPORATE SECURITIES LAW. THE SALE OF THE
SECURITIES WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH
THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF
THE SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION
THEREFOR PRIOR TO THE QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES

CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY
CONDITIONED UPON THE QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

                           PERSISTENCE SOFTWARE, INC.

                         COMMON STOCK PURCHASE AGREEMENT

         This Common Stock Purchase Agreement (the "Agreement") is made as of
____________, 199_ by and between Persistence Software, Inc. a California
corporation (the "Company"), and ________________ ("Purchaser").

         1. SALE OF STOCK. Subject to the terms and conditions of this
Agreement, on the Purchase Date (as defined below) the Company will issue and
sell to Purchaser, and Purchaser agrees to purchase from the Company, ________
shares of the Company's Common Stock (the "Shares") at a purchase price of
$_____ per Share for a total purchase price of $______. The term "Shares" refers
to the purchased Shares and all securities received in replacement of or in
connection with the Shares pursuant to stock dividends or splits, all securities
received in replacement of the Shares in a recapitalization, merger,
reorganization, exchange or the like, and all new, substituted or additional
securities or other properties to which Purchaser is entitled by reason of
Purchaser's ownership of the Shares.

         2. PURCHASE. The purchase and sale of the Shares under this Agreement
shall occur at the principal office of the Company simultaneously with the
execution of this Agreement by the parties, or on such other date as the Company
and Purchaser shall agree (the "Purchase Date"). On the Purchase Date, the
Company will deliver to Purchaser a certificate representing the Shares to be
purchased by Purchaser (which shall be issued in Purchaser's name) against
payment of the purchase price therefor by Purchaser by [delivery of a check made
payable to the Company] [delivery of a promissory note in the form attached as
Exhibit A to this Agreement and a Pledge and Security Agreement in the form
attached as Exhibit B to this Agreement] [surrender of _____ Shares of Common
Stock owned by Purchaser for at least six months plus delivery of a check made
payable to the Company in the amount of $___] [description of other combination
of acceptable consideration].

         3. LIMITATIONS ON TRANSFER. In addition to any other limitation on
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below), except as provided below.
After any Shares have been released from the Repurchase Option, Purchaser shall
not assign, encumber or dispose of any interest in such Shares except in
compliance with the provisions below and applicable securities laws.

            (a) REPURCHASE OPTION.

                (i) In the event of the voluntary or involuntary termination of
Purchaser's employment or consulting relationship with the Company for any
reason (including death or disability), with or without cause, the Company shall
upon the date of such termination (the "Termination Date") have an irrevocable,
exclusive option (the "Repurchase Option") for a period of 60 days from such
date to repurchase all or any portion of the Shares held by Purchaser as of the
Termination Date which have not yet been released from the Company's Repurchase
Option at the original purchase price per Share specified in Section 1 (adjusted
for any stock
<PAGE>   36
splits, stock dividends and the like); provided, however, that the Repurchase
Option shall continue for a period of up to one year from the Termination Date
to the extent that the Company reasonably determines that such an extension of
time is necessary to prevent the repurchase of Purchaser's Shares from causing
other capital stock of the Company to not qualify as "small business stock"
under Section 1202 of the Internal Revenue Code of 1986, as amended.

                (ii) The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

                (iii) __________ percent (___%) of the Shares shall initially be
subject to the Repurchase Option. The Shares shall be released from the
Repurchase Option in accordance with the following Vesting Schedule: [Example:
___ of the total number of Shares shall be released from the Repurchase Option
on the ___-month anniversary of the Vesting Commencement Date (as set forth on
the signature page of this Agreement), and an additional ___ of the total number
of Shares shall be released from the Repurchase Option at the end of each month
thereafter, until all Shares are released from the Repurchase Option] (provided
in each case that Purchaser's Continuous Service has not been terminated prior
to the date of any such release). Fractional shares shall be rounded to the
nearest whole share.

            (b) RIGHT OF FIRST REFUSAL. Before any Shares held by Purchaser or
any transferee of Purchaser (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(b) (the "Right of First Refusal").

                (i) NOTICE OF PROPOSED TRANSFER. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (A) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (B) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (C) the
number of Shares to be transferred to each Proposed Transferee; and (D) the
terms and conditions of each proposed sale or transfer. The Holder shall offer
the Shares at the same price (the "Offered Price") and upon the same terms (or
terms as similar as reasonably possible) to the Company or its assignee(s).

                (ii) EXERCISE OF RIGHT OF FIRST REFUSAL. At any time within
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice


                                      -2-
<PAGE>   37
to the Holder, elect to purchase all, but not less than all, of the Shares
proposed to be transferred to any one or more of the Proposed Transferees, at
the purchase price determined in accordance with subsection (iii) below.

                (iii) PURCHASE PRICE. The purchase price ("Purchase Price") for
the Shares purchased by the Company or its assignee(s) under this Section 3(b)
shall be the Offered Price. If the Offered Price includes consideration other
than cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

                (iv) PAYMENT. Payment of the Purchase Price shall be made, at
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

                (v) HOLDER'S RIGHT TO TRANSFER. If all of the Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section 3(b), then the
Holder may sell or otherwise transfer such Shares to that Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 60 days after the date of the Notice and provided
further that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section 3 shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, or if the Holder
proposes to change the price or other terms to make them more favorable to the
Proposed Transferee, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

                (vi) EXCEPTION FOR CERTAIN FAMILY TRANSFERS. Anything to the
contrary contained in this Section 3(b) notwithstanding, the transfer of any or
all of the Shares during Purchaser's lifetime or on Purchaser's death by will or
intestacy to Purchaser's Immediate Family or a trust for the benefit of
Purchaser's Immediate Family shall be exempt from the provisions of this Section
3(b). "Immediate Family" as used herein shall mean spouse, lineal descendant or
antecedent, father, mother, brother or sister. In such case, the transferee or
other recipient shall receive and hold the Shares so transferred subject to the
provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section 3.

            (c) INVOLUNTARY TRANSFER.

                (i) COMPANY'S RIGHT TO PURCHASE UPON INVOLUNTARY TRANSFER. In
the event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including death or divorce, but
excluding a transfer to Immediate Family as set forth in Section 3(b)(vi) above)
of all or a portion of the Shares by the record


                                      -3-
<PAGE>   38
holder thereof, the Company shall have an option to purchase all of the Shares
transferred at the greater of the purchase price paid by Purchaser pursuant to
this Agreement or the fair market value of the Shares on the date of transfer.
Upon such a transfer, the person acquiring the Shares shall promptly notify the
Secretary of the Company of such transfer. The right to purchase such Shares
shall be provided to the Company for a period of thirty (30) days following
receipt by the Company of written notice by the person acquiring the Shares.

                (ii) PRICE FOR INVOLUNTARY TRANSFER. With respect to any stock
to be transferred pursuant to Section 3(c)(i), the price per Share shall be a
price set by the Board of Directors of the Company that will reflect the current
value of the stock in terms of present earnings and future prospects of the
Company. The Company shall notify Purchaser or his or her executor of the price
so determined within thirty (30) days after receipt by it of written notice of
the transfer or proposed transfer of Shares. However, if the Purchaser does not
agree with the valuation as determined by the Board of Directors of the Company,
the Purchaser shall be entitled to have the valuation determined by an
independent appraiser to be mutually agreed upon by the Company and the
Purchaser and whose fees shall be borne equally by the Company and the
Purchaser.

            (d) ASSIGNMENT. The right of the Company to purchase any part of the
Shares may be assigned in whole or in part to any shareholder or shareholders of
the Company or other persons or organizations; provided, however, that an
assignee, other than a corporation that is the parent or a 100% owned subsidiary
of the Company, must pay the Company, upon assignment of such right, cash equal
to the difference between the original purchase price and fair market value, if
the original purchase price is less than the fair market value of the Shares
subject to the assignment.

            (e) RESTRICTIONS BINDING ON TRANSFEREES. All transferees of Shares
or any interest therein will receive and hold such Shares or interest subject to
the provisions of this Agreement, including, insofar as applicable, the
Repurchase Option. Any sale or transfer of the Company's Shares shall be void
unless the provisions of this Agreement are met.

            (f) TERMINATION OF RIGHTS. The right of first refusal granted the
Company by Section 3(b) above and the option to repurchase the Shares in the
event of an involuntary transfer granted the Company by Section 3(c) above shall
terminate upon the first sale of Common Stock of the Company to the general
public pursuant to a registration statement filed with and declared effective by
the Securities and Exchange Commission under the Securities Act of 1933, as
amended (the "Securities Act"). Upon termination of the right of first refusal
described in Section 3(b) and the expiration or exercise of the Repurchase
Option, a new certificate or certificates representing the Shares not
repurchased shall be issued, on request, without the legend referred to in
Section 6(a)(ii) below and delivered to Purchaser.

         4. ESCROW OF UNVESTED SHARES. For purposes of facilitating the
enforcement of the provisions of Section 3 above, Purchaser agrees, immediately
upon receipt of the certificate(s) for the Shares subject to the Repurchase
Option, to deliver such certificate(s), together with an Assignment Separate
from Certificate in the form attached to this Agreement as Exhibit C


                                      -4-
<PAGE>   39
executed by Purchaser and by Purchaser's spouse (if required for transfer), in
blank, to the Secretary of the Company, or the Secretary's designee, to hold
such certificate(s) and Assignment Separate from Certificate in escrow and to
take all such actions and to effectuate all such transfers and/or releases as
are in accordance with the terms of this Agreement. Purchaser hereby
acknowledges that the Secretary of the Company, or the Secretary's designee, is
so appointed as the escrow holder with the foregoing authorities as a material
inducement to make this Agreement and that said appointment is coupled with an
interest and is accordingly irrevocable. Purchaser agrees that said escrow
holder shall not be liable to any party hereof (or to any other party). The
escrow holder may rely upon any letter, notice or other document executed by any
signature purported to be genuine and may resign at any time. Purchaser agrees
that if the Secretary of the Company, or the Secretary's designee, resigns as
escrow holder for any or no reason, the Board of Directors of the Company shall
have the power to appoint a successor to serve as escrow holder pursuant to the
terms of this Agreement.

         5. INVESTMENT AND TAXATION REPRESENTATIONS. In connection with the
purchase of the Shares, Purchaser represents to the Company the following:

            (a) Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Shares. Purchaser is
purchasing the Shares for investment for his or her own account only and not
with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act.

            (b) Purchaser understands that the Shares have not been registered
under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.

            (c) Purchaser understands that the Shares are "restricted
securities" under applicable U.S. federal and state securities laws and that,
pursuant to these laws, Purchaser must hold the Shares indefinitely unless they
are registered with the Securities and Exchange Commission and qualified by
state authorities, or an exemption from such registration and qualification
requirements is available. Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale. Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

            (d) Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection the purchase or disposition of the Shares and that
Purchaser is not relying on the Company for any tax advice.

         6. RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

            (a) LEGENDS. The certificate or certificates representing the Shares
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

                (i)   THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                      REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN
                      ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
                      CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH
                      SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE
                      REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF
                      COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH
                      REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF
                      1933.

                (ii)  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE
                      TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN
                      AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY
                      OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

                (iii) Any legend required to be placed thereon by the California
                      Commissioner of Corporations.

            (b) STOP-TRANSFER NOTICES. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

            (c) REFUSAL TO TRANSFER. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

         7. NO EMPLOYMENT RIGHTS. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a parent or subsidiary
of the Company, to terminate Purchaser's employment, for any reason, with or
without cause.

         8. SECTION 83(B) ELECTION. Purchaser understands that Section 83(a) of
the Internal Revenue Code of 1986, as amended (the "Code"), taxes as ordinary
income the difference


                                      -6-
<PAGE>   41
between the amount paid for the Shares and the fair market value of the Shares
as of the date any restrictions on the Shares lapse. In this context,
"restriction" means the right of the Company to buy back the Shares pursuant to
the Repurchase Option set forth in Section 3(a) of this Agreement. Purchaser
understands that Purchaser may elect to be taxed at the time the Shares are
purchased, rather than when and as the Repurchase Option expires, by filing an
election under Section 83(b) (an "83(b) Election") of the Code with the Internal
Revenue Service within 30 days from the date of purchase. Even if the fair
market value of the Shares at the time of the execution of this Agreement equals
the amount paid for the Shares, the election must be made to avoid income under
Section 83(a) in the future. Purchaser understands that failure to file such an
election in a timely manner may result in adverse tax consequences for
Purchaser. Purchaser further understands that an additional copy of such
election form should be filed with his or her federal income tax return for the
calendar year in which the date of this Agreement falls. Purchaser acknowledges
that the foregoing is only a summary of the effect of United States federal
income taxation with respect to purchase of the Shares hereunder, and does not
purport to be complete. Purchaser further acknowledges that the Company has
directed Purchaser to seek independent advice regarding the applicable
provisions of the Code, the income tax laws of any municipality, state or
foreign country in which Purchaser may reside, and the tax consequences of
Purchaser's death.

             Purchaser agrees that he will execute and deliver to the Company
with this executed Agreement a copy of the Acknowledgment and Statement of
Decision Regarding Section 83(b) Election (the "Acknowledgment"), attached
hereto as Exhibit D. Purchaser further agrees that Purchaser will execute and
submit with the Acknowledgment a copy of the 83(b) Election, attached hereto as
Exhibit E, if Purchaser has indicated in the Acknowledgment his or her decision
to make such an election.

         9.  MARKET STANDOFF AGREEMENT. In connection with the initial public
offering of the Company's securities and upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any Shares (other than those included
in the registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed 180
days) from the effective date of such registration as may be requested by the
Company or such managing underwriters and to execute an agreement reflecting the
foregoing as may be requested by the underwriters at the time of the public
offering.

         10. MISCELLANEOUS.

             (a) GOVERNING LAW. This Agreement and all acts and transactions

provision shall be excluded from this Agreement, (ii) the balance of the
Agreement shall be interpreted as if such provision were so excluded and (iii)

                          PLEDGE AND SECURITY AGREEMENT


         This Pledge and Security Agreement (the "Agreement") is entered into
this _____ day of _________, 199_ by and between Persistence Software, Inc. a
California corporation (the "Company") and ________________ ("Purchaser").

                                    RECITALS

         In connection with Purchaser's purchase of certain shares of the
Company's Common Stock (the "Shares") pursuant to a Common Stock Purchase
Agreement dated _______________, 199_ between Purchaser and the Company,
Purchaser is delivering a promissory note of even date herewith (the "Note") in
full or partial payment of the exercise price for the Shares. The company
requires that the Note be secured by a pledge of the Shares on the terms set
forth below.

                                    AGREEMENT

         In consideration of the Company's acceptance of the Note as full or
partial payment of the exercise price of the Shares, and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the parties
hereto agree as follows:

         1. The Note shall become payable in full upon the voluntary or
involuntary termination or cessation of employment of Purchaser with the
Company, for any reason, with or without cause (including death or disability).

         2. Purchaser shall deliver to the Secretary of the Company, or his or
her designee (hereinafter referred to as the "Pledge Holder"), all certificates
representing the Shares, together with an Assignment Separate from Certificate
in the form attached to this Agreement as Attachment A executed by Purchaser and
by Purchaser's spouse (if required for transfer), in blank, for use in
transferring all or a portion of the Shares to the Company if, as and when
required pursuant to this Agreement. In addition, if Purchaser is married,
Purchaser's spouse shall execute the signature page attached to this Agreement.

         3. As security for the payment of the Note and any renewal, extension
or modification of the Note, Purchaser hereby grants to the Company a security
interest in and pledges with and delivers to the Company Purchaser's Shares
(sometimes referred to herein as the "Collateral").

         4. In the event that Purchaser prepays all or a portion of the Note, in
accordance with the provisions thereof, Purchaser intends, unless written notice
to the contrary is delivered to the Pledge Holder, that the Shares represented
by the portion of the Note so repaid, including annual interest thereon, shall
continue to be so held by the Pledge Holder, to serve as independent collateral
for the outstanding portion of the Note for the purpose of commencing the
holding
<PAGE>   46
period set forth in Rule 144(d) promulgated under the Securities Act of 1933, as
amended (the "Securities Act").

         5. In the event of any foreclosure of the security interest created by
this Agreement, the Company may sell the Shares at a private sale or may
repurchase the Shares itself. The parties agree that, prior to the establishment
of a public market for the Shares of the Company, the securities laws affecting
sale of the Shares make a public sale of the Shares commercially unreasonable.
The parties further agree that the repurchasing of such Shares by the Company,
or by any person to whom the Company may have assigned its rights under this
Agreement, is commercially reasonable if made at a price determined by the Board
of Directors in its discretion, fairly exercised, representing what would be the
fair market value of the Shares reduced by any limitation on transferability,
whether due to the size of the block of shares or the restrictions of applicable
securities laws.

         6. In the event of default in payment when due of any indebtedness
under the Note, the Company may elect then, or at any time thereafter, to
exercise all rights available to a secured party under the California Commercial
Code including the right to sell the Collateral at a private or public sale or
repurchase the Shares as provided above. The proceeds of any sale shall be
applied in the following order:

            (a) To the extent necessary, proceeds shall be used to pay all
reasonable expenses of the Company in enforcing this Agreement and the Note,
including, without limitation, reasonable attorney's fees and legal expenses
incurred by the Company.

            (b) To the extent necessary, proceeds shall be used to satisfy any
remaining indebtedness under Purchaser's Note.

            (c) Any remaining proceeds shall be delivered to Purchaser.

         7. Upon full payment by Purchaser of all amounts due under the Note,
Pledge Holder shall deliver to Purchaser all Shares in Pledge Holder's
possession belonging to Purchaser, and Pledge Holder shall thereupon be
discharged of all further obligations under this Agreement; provided, however,
that Pledge Holder shall nevertheless retain the Shares as escrow agent if at
the time of full payment by Purchaser said Shares are still subject to a
Repurchase Option in favor of the Company.

                             STOCK OPTION AGREEMENT


         1. GRANT OF OPTION. Persistence Software, Inc., a Delaware corporation
(the "Company"), hereby grants to <<Optionee>> ("Optionee"), an option (the
"Option") to purchase a total number of shares of Common Stock (the "Shares")
set forth in the Notice of Stock Option Grant, at the exercise price per share
set forth in the Notice of Stock Option Grant (the "Exercise Price") subject to
the terms, definitions and provisions of the Persistence Software, Inc. Stock
Option Plan (the "Plan") adopted by the Company, which is incorporated herein by
reference. Unless otherwise defined herein, the terms defined in the Plan shall
have the same defined meanings in this Option Agreement. In the event of a
conflict between the terms and conditions of the Plan and the terms and
conditions of this Option Agreement, the terms and conditions of the Plan shall
prevail.

                  To the extent designated an Incentive Stock Option in the
Notice of Stock Option Grant, this Option is intended to qualify as an Incentive
Stock Option as defined in Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code") and, to the extent not so designated, this Option is
intended to be a Nonstatutory Stock Option. Notwithstanding the foregoing, if
designated as an Incentive Stock Option, in the event that the Shares subject to
this Option (and all other Incentive Stock Options granted to Optionee by the
Company or any Parent or Subsidiary) that first become exercisable in any
calendar year have an aggregate fair market value (determined for each Share as
of the date of grant of the option covering such Share) in excess of $100,000,
the Shares in excess of $100,000 shall be treated as subject to a Nonstatutory
Stock Option, in accordance with Section 5(b) of the Plan.

         2.       EXERCISE OF OPTION.

                  (a) RIGHT TO EXERCISE. This Option is exercisable during its
Term in accordance with the Vesting Schedule set out in the Notice of Stock
Option Grant and the applicable provisions of the Plan and this Stock Option
Agreement. In the event of Optionee's death, disability or the termination of
Optionee's Continuous Service, the exercisability of the Option is governed by
the applicable provisions of the Plan and this Stock Option Agreement. This
Option may not be exercised for a fraction of a Share.

                  (b)      METHOD OF EXERCISE.

                           (i) This Option shall be exercisable in whole or in
part as to Shares which have vested under the Vesting Schedule indicated on the
Notice of Stock Option Grant by execution and delivery to the Company a written
notice of exercise in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as to the holder's
<PAGE>   57
investment intent with respect to such Shares of Common Stock as may be required
by the Company pursuant to the provisions of the Plan. Such written notice of
exercise shall be signed by Optionee and shall be delivered in person or by
certified mail to the Secretary of the Company. The written notice of exercise
shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed written notice of exercise, accompanied by
such aggregate Exercise Price.

                           (ii) As a condition to the exercise of this Option,
Optionee agrees to make adequate provision for
federal, state or other tax withholding obligations, if any, which arise upon
the exercise of the Option or disposition of Shares, whether by withholding,
direct payment to the Company, or otherwise, as set forth in Section 11 of this
Agreement.

                           (iii) No Shares will be issued pursuant to the
exercise of an Option unless such issuance and such exercise shall comply with
all relevant provisions of applicable law and the requirements of any stock
exchange upon which the Shares may then be listed. Assuming such compliance, for
income tax purposes the Shares shall be considered transferred to Optionee on
the date on which the Option is exercised with respect to such Shares.

         3. METHOD OF PAYMENT. Payment of the Exercise Price shall be by any of
the following, or a combination thereof, at the election of Optionee:

                  (a) cash;

                  (b) check;

                  (c) surrender of other Shares of Common Stock of the Company
that (i) in the case of Shares acquired upon exercise of an Option, have either
been owned by Optionee for more than six (6) months on the date of surrender (or
such other period as may be required to avoid a charge to the Company's
earnings) or were not acquired, directly or indirectly, from the Company, and
(ii) have a fair market value on the date of surrender equal to the Exercise
Price of the Shares as to which the Option is being exercised; or

                  (d) if there is a public market for the Shares and they are
registered under the Securities Act of 1933, as amended, delivery of a properly
executed exercise notice together with irrevocable instructions to a broker to
deliver promptly to the Company the amount of sale or loan proceeds required to
pay the exercise price.

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


                                      -2-
<PAGE>   58
         5. TERMINATION OF CONTINUOUS SERVICE. In the event of termination of
Optionee's Continuous Service, Optionee may, to the extent otherwise so entitled
at the date of such termination (the "Termination Date"), exercise this Option
during the Termination Period set forth in the Notice of Stock Option Grant. To
the extent that Optionee was not entitled to exercise this Option at such
Termination Date, or if Optionee does not exercise this Option within the
Termination Period, the Option shall terminate.

         6. DISABILITY OF OPTIONEE.

                  (a) Notwithstanding the provisions of Section 5 above, in the
event of termination of Optionee's Continuous Service as a result of Optionee's
total and permanent disability (as defined in Section 22(e)(3) of the Code),
Optionee may, but only within twelve (12) months from the Termination Date (but
in no event later than the Expiration Date set forth in the Notice of Stock
Option Grant), exercise this Option to the extent Optionee was entitled to
exercise it as of such Termination Date. To the extent that Optionee was not
entitled to exercise the Option as of the Termination Date, or if Optionee does
not exercise such Option (to the extent so entitled) within the time specified
in this Section 6(a), the Option shall terminate.

                  (b) Notwithstanding the provisions of Section 5 above, in the
event of termination of Optionee's Continuous Service as a result of disability
not constituting a total and permanent disability (as set forth in Section
22(e)(3) of the Code), Optionee may, but only within six (6) months from the
Termination Date (but in no event later than the Expiration Date set forth in
the Notice of Stock Option Grant), exercise the Option to the extent Optionee
was entitled to exercise it as of such Termination Date; provided, however, that
if this is an Incentive Stock Option and Optionee fails to exercise this
Incentive Stock Option within three (3) months from the Termination Date, this
Option will cease to qualify as an Incentive Stock Option (as defined in Section
422 of the Code) and Optionee will be treated for federal income tax purposes as
having received ordinary income at the time of such exercise in an amount
generally measured by the difference between the Exercise Price for the Shares
and the fair market value of the Shares on the date of exercise. To the extent
that Optionee was not entitled to exercise the Option at the Termination Date,
or if Optionee does not exercise such Option to the extent so entitled within
the time specified in this Section 6(b), the Option shall terminate.

         7. DEATH OF OPTIONEE. In the event of the death of Optionee (a) during
the Term of this Option and while an Employee or Consultant of the Company and
having been in Continuous Service since the date of grant of the Option, or (b)
within thirty (30) days after Optionee's Termination Date, the Option may be
exercised at any time within six (6) months following the date of death (but in
no event later than the Expiration Date set forth in the Notice of Stock Option
Grant), by Optionee's estate or by a person who acquired the right to exercise
the Option by bequest or inheritance, but only to the extent of the right to
exercise that had accrued at the Termination Date.

         8. NON-TRANSFERABILITY OF OPTION. This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution or
pursuant to a


                                      -3-
<PAGE>   59
domestic relations order (as defined by the Code or rules thereunder), except as
set forth in the Notice of Stock Option Grant and subject to Applicable Laws.
This Option may be exercised during the lifetime of Optionee only by him or her
or by a transferee permitted by this Section 8. The terms of this Option shall
be binding upon the executors, administrators, heirs, successors and assigns of
Optionee.

         9. TERM OF OPTION. This Option may be exercised only within the Term
set forth in the Notice of Stock Option Grant, subject to the limitations set
forth in Section 7 of the Plan.

         10. TAX CONSEQUENCES. Optionee acknowledges that he or she has read the
brief summary set forth below of certain of the federal tax consequences of
exercise of this Option and disposition of the Shares under the laws in effect
as of the Date of Grant. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX
LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

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

                  (b) EXERCISE OF NONSTATUTORY STOCK OPTION. If this Option does
not qualify as an Incentive Stock Option, Optionee may incur regular federal
(and state) income tax liability upon the exercise of the Option. Optionee will
be treated as having received compensation income (taxable at ordinary income
tax rates) equal to the excess, if any, of the fair market value of the Shares
on the date of exercise over the Exercise Price. If Optionee is an employee, the
Company will be required to withhold from Optionee's compensation or collect
from Optionee and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise.

                  (c) DISPOSITION OF SHARES. In the case of a Nonstatutory Stock
Option, if Shares are held for more than 12 months, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. In the case of an Incentive Stock Option, if Shares
transferred pursuant to the Option are held for more than one year after
exercise and more than two years after the Date of Grant, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. If Shares purchased under an Incentive Stock Option are
disposed of within either of such two holding periods, then any gain realized on
such disposition will be treated as compensation income (taxable at ordinary
income rates) to the extent of the difference between the Exercise Price and the
lesser of (i) the fair market value of the Shares on the date of exercise, or
(ii) the sales proceeds of the Shares.

                                      -4-
<PAGE>   60
                  (d) NOTICE OF DISQUALIFYING DISPOSITION OF INCENTIVE STOCK
OPTION SHARES. If the Option granted to Optionee herein is an Incentive Stock
Option, and if Optionee sells or otherwise disposes of any of the Shares
acquired pursuant to the Incentive Stock Option on or before the later of (i)
the date two years after the Date of Grant, or (ii) the date one year after the
date of exercise, Optionee shall notify the Company in writing within thirty
(30) days after the date of any such disposition. Optionee acknowledges and
agrees that he or she may be subject to income tax withholding by the Company on
the compensation income recognized by Optionee from the early disposition by
payment in cash or out of the current earnings paid to Optionee.

         11. WITHHOLDING TAX OBLIGATIONS. Optionee acknowledges and agrees that
the delivery of any Shares under the Plan is conditioned on satisfaction by the
Optionee of applicable federal, state, local or foreign withholding tax
obligations that may arise in connection with the exercise of an Option. Such
withholding obligations shall be satisfied in accordance with the provisions of
Section 12 of the Plan.

         12. MARKET STANDOFF AGREEMENT. In connection with the initial public
offering of the Company's securities and upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities,
Optionee hereby agrees not to sell, make any short sale of, loan, grant any
option for the purchase of, or otherwise dispose of any Shares (other than those
included in the registration) without the prior written consent of the Company
or such underwriters, as the case may be, for such period of time (not to exceed
180 days) from the effective date of such registration as may be requested by
the Company or such managing underwriters and to execute an agreement reflecting
the foregoing as may be requested by the underwriters at the time of the public
offering.

which shall be deemed an original and all of which together shall constitute one

STOCK OPTION PLAN WHICH IS INCORPORATED HEREIN BY REFERENCE, SHALL CONFER UPON

RELATIONSHIP BY THE COMPANY, NOR SHALL IT INTERFERE IN ANY WAY WITH OPTIONEE'S
RIGHT OR THE COMPANY'S RIGHT TO TERMINATE OPTIONEE'S EMPLOYMENT OR CONSULTING
RELATIONSHIP AT ANY TIME, WITH OR WITHOUT CAUSE.

he or she is familiar with the terms and provisions thereof, and hereby accepts

understands all provisions of the Option. Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option.

                         COMMON STOCK PURCHASE AGREEMENT

         This Restricted Stock Purchase Agreement (the "Agreement") is made as
of __________________, 19__, by and between Persistence Software, Inc., a
Delaware corporation (the "Company"), and ____________________ ("Purchaser")
pursuant to the Company's 1997 Stock Plan.

         1. SALE OF STOCK. Subject to the terms and conditions of this
Agreement, on the Purchase Date (as defined below) the Company will issue and
sell to Purchaser, and Purchaser agrees to purchase from the Company,
_______________ shares of the Company's Common Stock (the "Shares") at a
purchase price of $_____ per Share for a total purchase price of
$_________________. The term "Shares" refers to the purchased Shares and all
securities received in replacement of or in connection with the Shares pursuant
to stock dividends or splits, all securities received in replacement of the
Shares in a recapitalization, merger, reorganization, exchange or the like, and
all new, substituted or additional securities or other properties to which
Purchaser is entitled by reason of Purchaser's ownership of the Shares.

         2. PURCHASE. The purchase and sale of the Shares under this Agreement
shall occur at the principal office of the Company, in accordance with Section
11 of the Plan, simultaneously with the execution of this Agreement by the
parties or on such other date as the Company and Purchaser shall agree (the
"Purchase Date"). On the Purchase Date, the Company will deliver to Purchaser a
certificate representing the Shares to be purchased by Purchaser (which shall be
issued in Purchaser's name) against payment of the purchase price therefor by
Purchaser by check made payable to the Company.

         3. LIMITATIONS ON TRANSFER. In addition to any other limitation on
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below). After any Shares have
been released from the Repurchase Option, Purchaser shall not assign, encumber
or dispose of any interest in such Shares except in compliance with the
provisions below and applicable securities laws.

                  (a)      REPURCHASE OPTION.

                            (i) In the event of the voluntary or involuntary
termination of Purchaser's Continuous Service for any reason (including death or
disability), with or without cause, the Company shall upon the date of such
termination (the "Termination Date") have an irrevocable, exclusive option (the
"Repurchase Option") for a period of 60 days from such date to repurchase all or
any portion of the Shares held by Purchaser as of the Termination Date which
have not yet been released from the Company's Repurchase Option at the original
purchase price per Share specified in Section 1 (adjusted for any stock splits,
stock dividends and the like).
<PAGE>   64
                            (ii) The Repurchase Option shall be exercised by the
Company by written notice to Purchaser or Purchaser's executor and, at the
Company's option, (A) by delivery to Purchaser or Purchaser's executor with such
notice of a check in the amount of the purchase price for the Shares being
purchased, or (B) in the event Purchaser is indebted to the Company, by
cancellation by the Company of an amount of such indebtedness equal to the
purchase price for the Shares being repurchased, or (C) by a combination of (A)
and (B) so that the combined payment and cancellation of indebtedness equals
such purchase price. Upon delivery of such notice and payment of the purchase
price in any of the ways described above, the Company shall become the legal and
beneficial owner of the Shares being repurchased and all rights and interest
therein or related thereto, and the Company shall have the right to transfer to
its own name the number of Shares being repurchased by the Company, without
further action by Purchaser.

                            (iii) _______ percent (___%) of the Shares shall
initially be subject to the Repurchase Option. The Shares shall be released from
the Repurchase Option in accordance with the following Vesting Schedule:
[Example:): __ of the total number of Shares shall be released from the
Repurchase Option on the __-month anniversary of the Vesting Commencement Date
(as set forth on the signature page of this Agreement), and an additional __ of
the total number of Shares shall be released from the Repurchase Option each
month thereafter, until all Shares are released from the Repurchase Option]
(provided in each case that Purchaser's Continuous Service has not been
terminated prior to the date of any such release). Fractional shares shall be
rounded to the nearest whole share.

                  (b) RESTRICTIONS BINDING ON TRANSFEREES. All transferees of
Shares or any interest therein will receive and hold such Shares or interest
subject to the provisions of this Agreement, including insofar as applicable the
Company's Repurchase Option. Any sale or transfer of the Shares shall be void
unless the provisions of this Agreement are satisfied.

                  (c) TERMINATION OF RIGHTS. Upon the expiration or exercise of
the Repurchase Option, a new certificate or certificates representing the Shares
not repurchased shall be issued, on request, without the legend referred to in
Section 5(a) below and delivered to Purchaser.

         4. ESCROW OF UNVESTED SHARES. For purposes of facilitating the
enforcement of the provisions of Section 3 above, Purchaser agrees, immediately
upon receipt of the certificate(s) for the Shares subject to the Repurchase
Option, to deliver such certificate(s), together with an Assignment Separate
from Certificate in the form attached to this Agreement as Exhibit A executed by
Purchaser and by Purchaser's spouse (if required for transfer), in blank, to the
Secretary of the Company, or the Secretary's designee, to hold such
certificate(s) and Assignment Separate from Certificate in escrow and to take
all such actions and to effectuate all such transfers and/or releases as are in
accordance with the terms of this Agreement. Purchaser hereby acknowledges that
the Secretary of the Company, or the Secretary's designee, is so appointed as
the escrow holder with the foregoing authorities as a material inducement to
make this Agreement and that said appointment is coupled with an interest and is
accordingly irrevocable. Purchaser agrees that said escrow holder shall not be
liable to any party hereof (or


                                      -3-
<PAGE>   65
to any other party). The escrow holder may rely upon any letter, notice or other
document executed by any signature purported to be genuine and may resign at any
time. Purchaser agrees that if the Secretary of the Company, or the Secretary's
designee, resigns as escrow holder for any or no reason, the Board of Directors
of the Company shall have the power to appoint a successor to serve as escrow
holder pursuant to the terms of this Agreement.

         5.       RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

                  (a) LEGENDS. The certificate or certificates representing the
Shares shall bear the following legend (as well as any legends required by
applicable state and federal corporate and securities laws):

                                    THE SHARES REPRESENTED BY THIS CERTIFICATE
                                    MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH
                                    THE TERMS OF AN AGREEMENT BETWEEN THE
                                    COMPANY AND THE SHAREHOLDER, A COPY OF WHICH
                                    IS ON FILE WITH THE SECRETARY OF THE
                                    COMPANY.

                  (b) STOP-TRANSFER NOTICES. Purchaser agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

                  (c) REFUSAL TO TRANSFER. The Company shall not be required (i)
to transfer on its books any Shares that have been sold or otherwise transferred
in violation of any of the provisions of this Agreement or (ii) to treat as
owner of such Shares or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares shall have been so
transferred.

         6. NO EMPLOYMENT RIGHTS. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a parent or subsidiary
of the Company, to terminate Purchaser's employment or consulting relationship,
for any reason, with or without cause.

         7. SECTION 83(B) ELECTION. Purchaser understands that Section 83(a) of
the Internal Revenue Code of 1986, as amended (the "Code"), taxes as ordinary
income the difference between the amount paid for the Shares and the fair market
value of the Shares as of the date any restrictions on the Shares lapse. In this
context, "restriction" means the right of the Company to buy back the Shares
pursuant to the Repurchase Option set forth in Section 3(a) of this Agreement.
Purchaser understands that Purchaser may elect to be taxed at the time the
Shares are purchased, rather than when and as the Repurchase Option expires, by
filing an election under Section 83(b) (an "83(b) Election") of the Code with
the Internal Revenue Service within 30 days from the date of purchase. Even if
the fair market value of the Shares at the time of the execution of this
Agreement equals the amount paid for the Shares, the election must be made to
avoid income under Section 83(a) in the future. Purchaser understands that
failure to file such an


                                      -4-
<PAGE>   66
election in a timely manner may result in adverse tax consequences for
Purchaser. Purchaser further understands that an additional copy of such
election form should be filed with his or her federal income tax return for the
calendar year in which the date of this Agreement falls. Purchaser acknowledges
that the foregoing is only a summary of the effect of United States federal
income taxation with respect to purchase of the Shares hereunder, and does not
purport to be complete. Purchaser further acknowledges that the Company has
directed Purchaser to seek independent advice regarding the applicable
provisions of the Code, the income tax laws of any municipality, state or
foreign country in which Purchaser may reside, the tax consequences of
Purchaser's death and the decision as to whether or not to file an 83(b)
Election in connection with the acquisition of the Shares.

         Purchaser agrees that he will execute and deliver to the Company with
this executed Agreement a copy of the Acknowledgment and Statement of Decision
Regarding Section 83(b) Election (the "Acknowledgment"), attached hereto as
Exhibit B. Purchaser further agrees that Purchaser will execute and submit with
the Acknowledgment a copy of the 83(b) Election, attached hereto as Exhibit C,
if Purchaser has indicated in the Acknowledgment his or her decision to make
such an election.

         8.       MISCELLANEOUS.

                  (a) GOVERNING LAW. This Agreement and all acts and
transactions pursuant hereto and the rights and obligations of the parties
hereto shall be governed, construed and interpreted in accordance with the laws
of the State of California, without giving effect to principles of conflicts of
law.

                  (b) ENTIRE AGREEMENT; ENFORCEMENT OF RIGHTS. This Agreement
sets forth the entire agreement and understanding of the parties relating to the
subject matter herein and merges all prior discussions between them. No
modification of or amendment to this Agreement, nor any waiver of any rights
under this Agreement, shall be effective unless in writing signed by the parties
to this Agreement. The failure by either party to enforce any rights under this
Agreement shall not be construed as a waiver of any rights of such party.

                  (c) SEVERABILITY. If one or more provisions of this Agreement
are held to be unenforceable under applicable law, the parties agree to
renegotiate such provision in good faith. In the event that the parties cannot
reach a mutually agreeable and enforceable replacement for such provision, then
(i) such provision shall be excluded from this Agreement, (ii) the balance of
this Agreement shall be interpreted as if such provision were so excluded and
(iii) the balance of this Agreement shall be enforceable in accordance with its
terms.

                  (d) CONSTRUCTION. This Agreement is the result of negotiations
between and has been reviewed by each of the parties hereto and their respective
counsel, if any; accordingly, this Agreement shall be deemed to be the product
of all of the parties hereto, and no ambiguity shall be construed in favor of or
against any one of the parties hereto.

                  (e) NOTICES. Any notice required or permitted by this
Agreement shall be in writing and shall be deemed sufficient when delivered
personally or sent by telegram or fax or 48

                  (f) COUNTERPARTS. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument.

                  (g) SUCCESSORS AND ASSIGNS. The rights and benefits of this
Agreement shall inure to the benefit of, and be enforceable by the Company's
successors and assigns. The rights and obligations of Purchaser under this
Agreement may only be assigned with the prior written consent of the Company.

given Offering Period shall be eligible to participate in such Offering Period
under the Plan, subject to the requirements of Section 5(a) and the limitations
imposed by Section 423(b) of the Code; provided, however, that eligible
Employees may not participate in more than one Offering Period at a time.

                  (b) Any provisions of the Plan to the contrary
notwithstanding, no Employee shall be granted an option under the Plan (i) to
the extent that, immediately after the grant, such Employee (or any other person
whose stock would be attributed to such Employee pursuant to Section 424(d) of
the Code) would own capital stock of the Company and/or hold outstanding options
to purchase stock possessing five percent (5%) or more of the total combined
voting power or value of all classes of stock of the Company or of any
Subsidiary, or (ii) to the extent such option would permit his or her rights to
purchase stock under all employee stock purchase plans (described in Section 423
of the Code) of the Company and its Subsidiaries to accrue at a rate which
exceeds twenty-five thousand dollars ($25,000) of Fair Market Value (as defined
in Section 2(l) above) of such stock (determined at the time such option is
granted) for each calendar year in which such option is outstanding at any time.

         4.       OFFERING PERIODS AND PURCHASE PERIODS.

                  (a) OFFERING PERIODS. The Plan shall be implemented by a
series of Offering Periods generally of twenty-four (24) months duration and not
exceeding twenty-seven (27) months duration, with new Offering Periods
commencing on or about February 1 and August 1


                                      -3-
<PAGE>   4
of each year, or at such other time or times as may be determined by the Board
of Directors. Offering Periods shall commence on a continuing and overlapping
basis until terminated in accordance with Section 21 hereof. Notwithstanding the
foregoing, the first Offering Period under the Plan shall commence on the
beginning of the effective date of the Registration Statement on Form S-1 for
the initial public offering of the Company's Common (the "IPO Date") and
continue until the last Trading Day on or before July 31, 2001. The Board of
Directors of the Company shall have the power to change the duration and/or the
frequency of Offering Periods with respect to future offerings without
stockholder approval if such change is announced at least five (5) days prior to
the scheduled beginning of the first Offering Period to be affected.

                  (b) PURCHASE PERIODS. Each Offering Period shall generally
consist of four (4) Purchase Periods of approximately six (6) months duration,
the first commencing on the Offering Date and ending on the July 31 or January
31 next following, and each other Purchase Period in such Offering Period
commencing on the day after the last day of the preceding Purchase Period and
ending on the July 31 or January 31 next following; provided, however, that the
first Purchase Period shall commence on the IPO Date and shall end on January
31, 2000. The Board of Directors of the Company shall have the power to change
the duration and/or frequency of Purchase Periods with respect to future
purchases without stockholder approval if such change is announced at least five
(5) days prior to the otherwise scheduled beginning of the first Purchase Period
to be affected.

         5.       PARTICIPATION.

                  (a) An eligible Employee may become a participant in the Plan
by completing a subscription agreement on the form provided by the Company and
filing it with the Company's payroll office prior to the applicable Offering
Date, unless a later time for filing the subscription agreement is set by the
Board for all eligible Employees with respect to a given Offering Period.

                  (b) The subscription agreement shall set forth the Employee's
participation election, either in the form of a designation of the percentage of
the Employee's Compensation the Employee elects to have deducted from his or her
pay on each pay day during the Offering Period and credited to his or her
account under the Plan to be used to purchase shares on the Purchase Date for
each of the relevant Purchase Periods, which percentage shall be not less than
one percent (1%) and not more than twenty percent (20%), or, if permitted by the
Board, in the form of a designation of the number of whole shares the Employee
elects to purchase at the end of each Purchase Period with respect to the
Offering Period, up to such maximum number of shares as the Board may establish
from time to time before an Offering Date.

                  (c) A participant's subscription shall be effective for each
successive Offering Period in which he or she is eligible to participate, unless
the participant withdraws in accordance with Section 11(a).

                  (d) In addition to the limits on an Employee's participation
in the Plan set forth herein, the Board may establish limits on the number of
shares an Employee may elect to


                                      -4-
<PAGE>   5
purchase with respect to any Offering Period if such limit is announced at least
fifteen (15) days prior to the scheduled beginning of the first Offering Period
to be affected.

                  6.       GRANT OF OPTION. On the Offering Date of each
Offering Period, each eligible Employee participating in such Offering Period
shall be granted an option to purchase on each Purchase Date a number of Shares
of the Company's Common Stock determined by dividing such Employee's
Contributions accumulated prior to such Purchase Date and retained in the
participant's account as of the Purchase Date by the applicable Purchase Price,
provided, however, that the maximum number of Shares an Employee may purchase
during each Purchase Period shall be 2,500 Shares (subject to adjustment
pursuant to Section 20 below), and provided further that such purchase shall be
subject to the limitations set forth in Sections 3(b) and 9(b).

                  7.       METHOD OF PAYMENT OF CONTRIBUTIONS.

                  (a)      PAYROLL DEDUCTIONS.

                           (i) If an Employee's participation election is in the
form of an election to contribute a percentage of his or her Compensation
through payroll deductions, or if an Employee otherwise elects to make
contributions to the Plan through payroll deductions of a specified percentage
of his or her Compensation as permitted by the Board with respect to an
Employee's participation election in the form of an election to purchase a
designated number of shares at the end of each Purchase Period, such payroll
deductions shall commence on the first payroll following the Offering Date and
shall end on the last payroll paid in the Offering Period to which such
subscription agreement and payroll deduction authorization is applicable, unless
sooner terminated by the participant as provided in Section 11. All payroll
deductions made by a participant shall be credited to his or her account under
the Plan.

                           (ii) A participant may discontinue his or her
participation in the Plan as provided in Section 11, or on one occasion only
during an Offering Period may increase and on one occasion only during an
Offering Period decrease the rate of his or her payroll deductions with respect
to the Offering Period by completing and filing with the Company a new
subscription agreement authorizing a change in payroll deduction rate. The
change in rate shall be effective as of the beginning of the next calendar month
commencing ten (10) or more business days after the date the new subscription is
filed.

                           (iii) Notwithstanding the foregoing, to the extent
necessary to comply with Section 423(b)(8) of the Code and Section 3(b) herein,
a participant's payroll deductions may be decreased by the Company to zero
percent (0%) at any time during a Purchase Period. Payroll deductions shall
re-commence at the rate provided in such participant's subscription agreement at
the beginning of the first Purchase Period which is scheduled to end in the
following calendar year, unless terminated by the participant as provided in
Section 11.

                  (b) CASH OR STOCK CONTRIBUTIONS. To the extent permitted by
the Board, a participant may make contributions to the Plan for purchase of
shares in cash or by tendering Company stock or by election to receive shares
representing the difference between the Purchase Price and the Fair Market Value
of the shares, less applicable withholding. Any such cash or


                                      -5-
<PAGE>   6
stock contribution, or any election to receive net shares, must be received by
the Company in accordance with procedures and at such times as established by
the Board, and a participant's failure to make such contributions or such an
election within the time required, to the extent the aggregate Purchase Price of
the number of shares the participant has an option to purchase on the Purchase
Date exceeds payroll deduction contributions made by the participant as of the
Purchase Date, shall be deemed a withdrawal from the Offering Period with
respect to shares subject to the option not purchased on the applicable Purchase
Date and with respect to all other Purchase Periods in such Offering Period.

         8.       WITHHOLDING TAX OBLIGATIONS. At the time the option is
exercised, in whole or in part, or at the time some or all of the Company's
Common Stock issued under the Plan is disposed of, the participant must make
adequate provision for payment to the Company of the Company's federal, state or
other tax withholding obligations, if any, which arise upon the exercise of the
option or the disposition of the Common Stock. At any time, the Company may, but
shall not be obligated to, withhold from the participant's compensation the
amount necessary for the Company to meet applicable withholding obligations,
including any withholding required to make available to the Company any tax
deductions or benefits attributable to the sale or early disposition of Common
Stock by the participant.

         9.       EXERCISE OF OPTION.

                  (a) Unless a participant withdraws from the Plan as provided
in Section 11, his or her option for the purchase of Shares will be exercised
automatically on each Purchase Date of an Offering Period, and the maximum
number of full Shares subject to the option will be purchased at the applicable
Purchase Price with the accumulated Contributions in his or her account. The
Shares purchased upon exercise of an option hereunder shall be deemed to be
transferred to the participant on the Purchase Date. During his or her lifetime,
a participant's option to purchase Shares hereunder is exercisable only by him
or her.

                  (b) If the Board determines that, on a given Purchase Date,
the number of Shares with respect to which options are to be exercised may
exceed (i) the number of Shares of Common Stock that were available for sale
under the Plan on the Offering Date of the applicable Offering Period (after
deduction of all Shares for which options have been exercised or are then
outstanding), or (ii) the number of shares available for sale under the Plan on
such Purchase Date (after deduction of all Shares for which options have been
exercised or are then outstanding), the Board may, in its sole discretion,
provide that the Shares of Common Stock available for purchase on such Offering
Date or Purchase Date, as applicable, shall be allocated pro rata, in as uniform
a manner as shall be practicable and as it shall determine in its sole
discretion to be equitable among all participants exercising options to purchase
Common Stock on such Purchase Date and (x) continue all Offering Periods then in
effect or (y) pursuant to Section 21 below, terminate any or all Offering
Periods then in effect. The Board may direct that the Shares available on the
Offering Date of any applicable Offering Period pursuant to the preceding
sentence be allocated pro rata, notwithstanding any authorization of additional
Shares for issuance under the Plan by the Company's stockholders subsequent to
such Offering Date.


                                      -6-
<PAGE>   7
                  (c) Any cash remaining to the credit of a participant's
account under the Plan after a purchase by him or her of Shares at the
termination of each Purchase Period which is insufficient to purchase a full
Share shall be carried over to the next Purchase Period if the Employee
continues to participate in the Plan, or if the Employee does not continue to
participate, shall be returned to the participant. Any other amounts left over
in a participant's account after a Purchase Date shall be returned to the
participant.

         10.      RIGHTS AS STOCKHOLDER; DELIVERY OF CERTIFICATE.

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

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

                  (c) As promptly as practicable after each Purchase Date of
each Offering Period, the Company shall arrange the delivery to each
participant, as appropriate, of a certificate representing the Shares purchased
upon exercise of his or her option.

         11.      VOLUNTARY WITHDRAWAL.

                  (a) A participant may withdraw all but not less than all the
Contributions credited to his or her account under the Plan at any time prior to
each Purchase Date by giving written notice to the Company. All of the
participant's Contributions credited to his or her account will be paid to him
or her promptly after receipt of his or her notice of withdrawal and his or her
option for the current Offering Period will be automatically terminated, and no
further Contributions for the purchase of Shares will be made during and with
respect to such Offering Period.

                  (b) A participant's voluntary withdrawal from the Plan with
respect to an Offering Period will not have any effect upon his or her
eligibility to participate in a succeeding Offering Period or in any similar
plan which may hereafter be adopted by the Company.

         12.      AUTOMATIC WITHDRAWAL.

                  (a) REDUCTION OF HOURS. In the event an Employee fails to
remain in Continuous Status as an Employee of the Company for at least twenty
(20) hours per week during the Offering Period in which the employee is a
participant, he or she will be deemed to have elected to withdraw from the Plan
and the Contributions credited to his or her account will be returned to him or
her and his or her option terminated.

                  (b) TERMINATION OF EMPLOYMENT. Upon termination of the
participant's Continuous Status as an Employee prior to the Purchase Date of an
Offering Period (other than on account of death), he or she will be
automatically withdrawn from the Plan effective as of the date of such
termination of his or her Continuous Status as an Employee, the Contributions


                                      -7-
<PAGE>   8
credited to his or her account will be returned to him or her, and his or her
option will be automatically terminated.

                  (c) DEATH OF PARTICIPANT. Upon the death of a participant
prior to the Purchase Date of an Offering Period, he or she will be
automatically withdrawn from the Plan, the Contributions credited to his or her
account will be returned to the person or persons entitled thereto under Section
16, and his or her option will be automatically terminated.

                  (d) REDUCTION IN FAIR MARKET VALUE. To the extent permitted by
any applicable laws, regulations or stock exchange rules, if the Fair Market
Value of the Shares on a Purchase Date of an Offering Period (other than the
final Purchase Date of such Offering Period) is less than the Fair Market Value
of the Shares on the Offering Date for such Offering Period, then every
participant shall automatically (i) be withdrawn from such Offering Period at
the close of such Purchase Date and after the acquisition of Shares for such
Purchase Period, and (ii) be enrolled in the first Offering Period commencing
subsequent to such Purchase Date. Participants shall automatically be withdrawn
as of July 31, 1999 from the Offering Period beginning on the IPO Date and
re-enrolled in the Offering Period beginning on August 1, 1999 if the Fair
Market Value of the Shares on the IPO Date is greater than the Fair Market Value
of the Shares on July 31, 1999, unless a participant notifies the Administrator
prior to July 31, 1999 that he or she does not wish to be withdrawn and
re-enrolled. All payroll deductions accumulated in a participant's account as of
a withdrawal date pursuant to this Section 12(d) shall be returned to the
participant.

         13.      INTEREST. No interest shall accrue on the Contributions of a
participant in the Plan.

         14.      STOCK. The maximum number of Shares which shall be made
available for sale under the Plan shall be 600,000 Shares, plus an annual
increase on the first day of each of the Company's fiscal years beginning in
2000, 2001, 2002, 2003 and 2004, equal to the lesser of (A) 250,000 Shares, (B)
1% of the Shares outstanding on the last day of the immediately preceding fiscal
year, or (C) such lesser number of Shares as is determined by the Board, subject
to adjustment upon changes in capitalization of the Company as provided in
Section 20.

         15.      ADMINISTRATION. The Board, or a committee named by the Board,
shall supervise and administer the Plan and shall have full power to adopt,
amend and rescind any rules deemed desirable and appropriate for the
administration of the Plan and not inconsistent with the Plan, to construe and
interpret the Plan, and to make all other determinations necessary or advisable
for the administration of the Plan. Every finding, decision and determination
made by the Board or its committee shall, to the full extent permitted by law,
be final and binding upon all parties.

         16.      DESIGNATION OF BENEFICIARY.

                  (a) A participant may file a written designation of a
beneficiary who is to receive any Shares and cash, if any, from the
participant's account under the Plan in the event of such participant's death
subsequent to the end of a Purchase Period but prior to delivery to him or her
of such Shares and cash. In addition, a participant may file a written
designation of a beneficiary who is to receive any cash from the participant's
account under the Plan in the event


                                      -8-
<PAGE>   9
of such participant's death prior to the Purchase Date of an Offering Period. If
a participant is married and the designated beneficiary is not the spouse,
spousal consent shall be required for such designation to be effective. Such
designation of beneficiary may be changed by the participant (with the consent
of his or her spouse, if any) at any time by written notice effective upon
receipt by the Company of such notice.

                  (b) In the absence of a beneficiary validly designated in
accordance with Section 16(a) who is living at the time of such participant's
death, upon the death of the participant the Company shall deliver such Shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such Shares and/or
cash to the spouse or to any one or more dependents or relatives of the
participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

         17.      TRANSFERABILITY. Neither Contributions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive Shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way by the participant (other than by will, the
laws of descent and distribution, or as provided in Section 16). Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds in accordance with Section 11.

         18.      USE OF FUNDS. All Contributions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such Contributions.

         19.      REPORTS. Individual accounts will be maintained for each
participant in the Plan. Statements of account will be given to participating
Employees at least annually, which statements will set forth the amounts of
Contributions, the per Share Purchase Price, the number of Shares purchased and
the remaining cash balance, if any.

         20.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE
                  TRANSACTIONS.

                  (a) ADJUSTMENT. Subject to any required action by the
stockholders of the Company, the number of Shares covered by each option under
the Plan which has not yet been exercised and the number of Shares which have
been authorized for issuance under the Plan but have not yet been placed under
option (collectively, the "Reserves"), as well as the maximum number of shares
of Common Stock which may be purchased by a participant in a Purchase Period,
the number of shares of Common Stock set forth in Section 14 above, and the
price per Share of Common Stock covered by each option under the Plan which has
not yet been exercised, shall be proportionately adjusted for any increase or
decrease in the number of issued Shares resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common Stock
(including any such change in the number of shares of Common Stock effected in
connection with a change in domicile of the Company), or any other increase or
decrease in the number of Shares effected without receipt of consideration by
the Company, which such increase or decrease occurs after the effective date of
this Plan; provided,


                                      -9-
<PAGE>   10
however, that conversion of any convertible securities of the Company shall not
be deemed to have been "effected without receipt of consideration." Such
adjustment shall be made by the Board, whose determination in that respect shall
be final, binding and conclusive. Except as expressly provided herein, no issue
by the Company of shares of stock of any class, or securities convertible into
shares of stock of any class, shall affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of Shares subject to an
option.

                  (b) CORPORATE TRANSACTIONS. In the event of a dissolution or
liquidation of the Company, any Purchase Period and Offering Period then in
progress will terminate immediately prior to the consummation of such action,
unless otherwise provided by the Board. In the event of a Corporate Transaction,
each option outstanding under the Plan shall be assumed or an equivalent option
shall be substituted by the successor corporation or a parent or subsidiary of
such successor corporation. In the event that the successor corporation refuses
to assume or substitute for outstanding options, each Purchase Period and
Offering Period then in progress shall be shortened and a new Purchase Date
shall be set (the "New Purchase Date"), as of which date any Purchase Period and
Offering Period then in progress will terminate. The New Purchase Date shall be
on or before the date of consummation of the transaction and the Board shall
notify each participant in writing, at least ten (10) days prior to the New
Purchase Date, that the Purchase Date for his or her option has been changed to
the New Purchase Date and that his or her option will be exercised automatically
on the New Purchase Date, unless prior to such date he or she has withdrawn from
the Offering Period as provided in Section 11. For purposes of this Section
20(b), an option granted under the Plan shall be deemed to be assumed, without
limitation, if, at the time of issuance of the stock or other consideration upon
a Corporate Transaction, each holder of an option under the Plan would be
entitled to receive upon exercise of the option the same number and kind of
shares of stock or the same amount of property, cash or securities as such
holder would have been entitled to receive upon the occurrence of the Corporate
Transaction if the holder had been, immediately prior to the Corporate
Transaction , the holder of the number of Shares of Common Stock covered by the
option at such time (after giving effect to any adjustments in the number of
Shares covered by the option as provided in Section 20(a)); provided however
that if the consideration received in the transaction is not solely common stock
of the successor corporation or its parent (as defined in Section 424(e) of the
Code), the Board may, with the consent of the successor corporation, provide for
the consideration to be received upon exercise of the option to be solely common
stock of the successor corporation or its parent equal in Fair Market Value to
the per Share consideration received by holders of Common Stock in the Corporate
Transaction.

         The Board may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per Share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of Shares of its outstanding Common
Stock, and in the event of the Company's being consolidated with or merged into
any other corporation.



                                      -10-
<PAGE>   11
         21.      AMENDMENT AND TERMINATION.

                  (a) The Board may at any time and for any reason terminate or
amend the Plan. Except as provided in Section 20, no such amendment or
termination of the Plan may affect options previously granted, provided that the
Plan or an Offering Period may be terminated by the Board on a Purchase Date or
by the Board's setting a new Purchase Date with respect to an Offering Period
and Purchase Period then in progress if the Board determines that termination of
the Plan and/or the Offering Period is in the best interests of the Company and
the stockholders or if continuation of the Plan and/or the Offering Period would
cause the Company to incur adverse accounting charges as a result of a change
after the effective date of the Plan in the generally accepted accounting rules
applicable to the Plan. Except as provided in Section 20 and this Section 21, no
amendment to the Plan shall make any change in any option previously granted
which adversely affects the rights of any participant. In addition, to the
extent necessary to comply with Section 423 of the Code (or any successor rule
or provision or any other applicable law or regulation) or Rule 16b-3 under the
Exchange Act, the Company shall obtain stockholder approval in such a manner and
to such a degree as so required.

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

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

         23. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such Shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, applicable state securities laws and the requirements of
any stock exchange upon which the Shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

         As a condition to the exercise of an option, the Company may require
the person exercising such option to represent and warrant at the time of any
such exercise that the Shares


                                      -11-
<PAGE>   12
are being purchased only for investment and without any present intention to
sell or distribute such Shares if, in the opinion of counsel for the Company,
such a representation is required by any of the aforementioned applicable
provisions of law.

         24.      TERM OF PLAN; EFFECTIVE DATE. The Plan shall become effective
upon the IPO Date. It shall continue in effect for a term of twenty (20) years
unless sooner terminated under Section 21.

         25.      ADDITIONAL RESTRICTIONS OF RULE 16b-3. The terms and
conditions of options granted hereunder to, and the purchase of Shares by,
persons subject to Section 16 of the Exchange Act shall comply with the
applicable provisions of Rule 16b-3. This Plan shall be deemed to contain, and
such options shall contain, and the Shares issued upon exercise thereof shall be
subject to, such additional conditions and restrictions as may be required by
Rule 16b-3 to qualify for the maximum exemption from Section 16 of the Exchange
Act with respect to Plan transactions.

         8.       In the event of my death, I hereby designate the following as

(Relationship)                         (Address)

                   Summary of Tax Treatment on Sale of Shares

         The following information regarding the federal tax treatment on sale
of shares acquired under the Plan is only a summary and is subject to change,
and is not intended to represent or provide tax advice to the participant, his
or her spouse or beneficiaries. You should consult a tax advisor concerning the
tax implications of the purchase and sale of stock under the Plan.

         If any shares received pursuant to the Plan are sold or otherwise
disposed of within two (2) years after the first day of the Offering Period
during which I purchased such shares or within one (1) year after the Purchase
Date, the excess of the fair market value of the shares on the Purchase Date
over the price paid for the shares on such Purchase Date will be treated for
federal income tax purposes as ordinary compensation income at the time of such
disposition, regardless of the amount received on sale or other disposition of
the shares, even if such amount is less than their fair market value at the
Purchase Date. The remainder of the gain or loss, if any, recognized on such
disposition will be treated as capital gain or loss.


                                      -2-
<PAGE>   15
         If any shares received pursuant to the Plan are sold or otherwise
disposed of at any time after expiration of the 2-year and 1-year holding
periods, the lesser of 15% of the fair market value of the shares on the
Offering Date or the excess of the fair market value of the shares at the time
of such sale or disposition over the price paid for the shares on the Purchase
Date will be treated for federal income tax purposes as ordinary compensation
income. The remainder of the gain or loss, if any, recognized on such
disposition will be treated as capital gain or loss.

         9. I hereby agree to notify the Company in writing within 30 days after
the date of any disposition of shares within two (2) years after the first day
of the Offering Period during which I purchased such shares or within one (1)
year after the Purchase Date, and I will make adequate provision for federal,
state or other tax withholding obligations, if any, which arise upon the
disposition of the Common Stock. The Company may, but will not be obligated to,
withhold from my compensation the amount necessary to meet any applicable
withholding obligation including any withholding necessary to make available to
the Company any tax deductions or benefits attributable to the sale or early
disposition of Common Stock by me.

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

with the following provisions:

DIRECTOR                              -2-


<PAGE>   3
                           (i) No person shall have any discretion to select
which Outside Directors shall be granted Options or to determine the number of
Shares to be covered by Options granted to Outside Directors.

                           (ii) Each person who becomes an Outside Director
after the effective date of this Plan (a "New Outside Director") shall
automatically be granted an Option to purchase 20,000 Shares (the "First
Option") on the date on which such person first becomes an Outside Director,
whether through election by the stockholders of the Company or appointment by
the Board to fill a vacancy.

                           (iii) Each New Outside Director shall automatically
be granted an Option to purchase 20,000 Shares (the "Second Option") on the
first anniversary of the date such New Outside Director first became an Outside
Director, provided his or her Continuous Status as a Director has not terminated
on such date.

                           (iv) Each New Outside Director shall thereafter
automatically be granted an Option to purchase 4,000 Shares (a "Subsequent
Option") on the first day of each fiscal year beginning at least two years after
the date on which such person first became an Outside Director, provided his or
her Continuous Status as a Director has not terminated on such date.

                           (v) Each Outside  Director who was an Outside
Director prior to the effective date of this Plan shall automatically be granted
an Option to purchase 4,000 Shares on the first day of each fiscal year
beginning on and after January 1, 2000, provided his or her Continuous Status as
a Director has not terminated on such date.

                           (vi)     Notwithstanding  the  preceding  provisions
hereof, in the event that a grant would cause the number of Shares subject to
outstanding Options plus the number of Shares previously purchased upon exercise
of Options to exceed the Pool, then each such automatic grant shall be for that
number of Shares determined by dividing the total number of Shares remaining
available for grant by the number of Outside Directors receiving an Option on
the automatic grant date. Any further grants shall then be deferred until such
time, if any, as additional Shares become available for grant under the Plan
through action of the stockholders to increase the number of Shares which may be
issued under the Plan or through cancellation or expiration of Options
previously granted hereunder.

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

                  (c) TERMS OF THE OPTIONS. The terms of each Option granted
hereunder shall be as follows:

                           (i)      each Option shall be exercisable only while
the Outside Director remains a Director of the Company, except as set forth in
Section 8 below;

DIRECTOR                              -3-
<PAGE>   4
                           (ii) the exercise price per Share shall be 100% of
the fair market value per Share on the date of grant of each Option, determined
in accordance with Section 8 hereof;

                           (iii)    each Option shall have a term of ten (10)
years from the date of grant thereof unless an Option terminates sooner pursuant
to Section 8 below; and

                           (iv) each Option shall be exercisable in its entirety
immediately upon grant.

                  (d) POWERS OF THE BOARD. Subject to the provisions and
restrictions of the Plan, the Board shall have the authority, in its discretion:
(i) to determine, upon review of relevant information and in accordance with
Section 7(b) of the Plan, the fair market value of the Common Stock; (ii) to
determine the exercise price per Share of Options to be granted, which exercise
price shall be determined in accordance with Section 7 of the Plan; (iii) to
interpret the Plan; (iv) to prescribe, amend and rescind rules and regulations
relating to the Plan; (v) to authorize any person to execute on behalf of the
Company any instrument required to effectuate the grant of an Option previously
granted hereunder; and (vi) to make all other determinations deemed necessary or
advisable for the administration of the Plan.

                  (e) EFFECT OF BOARD'S DECISION. All decisions, determinations
and interpretations of the Board shall be final and binding on all Optionees and
any other holders of any Options granted under the Plan.

                  (f) SUSPENSION OR TERMINATION OF OPTION. If the Chief
Executive Officer or his or her designee reasonably believes that an Optionee
has committed an act of misconduct, such officer may suspend the Optionee's
right to exercise any option pending a determination by the Board (excluding the
Outside Director accused of such misconduct). If the Board (excluding the
Outside Director accused of such misconduct) determines an Optionee has
committed an act of embezzlement, fraud, dishonesty, nonpayment of an obligation
owed to the Company, breach of fiduciary duty or deliberate disregard of the
Company rules resulting in loss, damage or injury to the Company, or if an
Optionee makes an unauthorized disclosure of any Company trade secret or
confidential information, engages in any conduct constituting unfair
competition, induces any Company customer to breach a contract with the Company
or induces any principal for whom the Company acts as agent to terminate such
agency relationship, neither the Optionee nor his or her estate shall be
entitled to exercise any Option whatsoever. In making such determination, the
Board of Directors (excluding the Outside Director accused of such misconduct)
shall act fairly and shall give the Optionee an opportunity to appear and
present evidence on Optionee's behalf at a hearing before the Board or a
committee of the Board.

         5. ELIGIBILITY. Options may be granted only to Outside Directors. All
Options shall be automatically granted in accordance with the terms set forth in
Section 4(b) above. An Outside Director who has been granted an Option may, if
he or she is otherwise eligible, be granted an additional Option or Options in
accordance with such provisions.

                  The Plan shall not confer upon any Optionee any right with
respect to continuation of service as a Director or nomination to serve as a
Director, nor shall it interfere in

DIRECTOR                              -4-
<PAGE>   5
any way with any rights which the Director or the Company may have to terminate
his or her directorship at any time.

         6. TERM OF PLAN; EFFECTIVE DATE. The Plan shall become effective on the
effectiveness of the registration statement under the Securities Act of 1933, as
amended, relating to the Company's initial public offering of securities. It
shall continue in effect for a term of ten (10) years unless sooner terminated
under Section 12 of the Plan.

         7.       EXERCISE PRICE AND CONSIDERATION.

                  (a) EXERCISE PRICE. The per Share exercise price for the
Shares to be issued pursuant to exercise of an Option shall be 100% of the fair
market value per Share on the date of grant of the Option.

                  (b) FAIR MARKET VALUE. The fair market value shall be
determined by the Board; provided however that in the event the Common Stock is
traded on the Nasdaq National Market or listed on a stock exchange, the fair
market value per Share shall be the closing sales price on such system or
exchange on the date of grant of the Option (or, in the event that the Common
Stock is not traded on such date, on the immediately preceding trading date), as
reported in The Wall Street Journal, or if there is a public market for the
Common Stock but the Common Stock is not traded on the Nasdaq National Market or
listed on a stock exchange, the fair market value per Share shall be the mean of
the bid and asked prices of the Common Stock in the over-the-counter market on
the date of grant, as reported in The Wall Street Journal (or, if not so
reported, as otherwise reported by the National Association of Securities
Dealers Automated Quotation ("Nasdaq") System).

                  (c) FORM OF CONSIDERATION. The consideration to be paid for
the Shares to be issued upon exercise of an Option shall consist entirely of
cash, check, other Shares of Common Stock having a fair market value on the date
of surrender equal to the aggregate exercise price of the Shares as to which the
Option shall be exercised (which, if acquired from the Company, shall have been
held for at least six months), or any combination of such methods of payment
and/or any other consideration or method of payment as shall be permitted under
applicable corporate law.

         8.       EXERCISE OF OPTION.

                  (a) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any
Option granted hereunder shall be exercisable at such times as are set forth in
Section 4(b) above; provided however that no Options shall be exercisable prior
to stockholder approval of the Plan in accordance with Section 16 below has been
obtained.

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

                           An Option shall be deemed to be exercised when
written notice of such exercise has been given to the Company in accordance with
the terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the

DIRECTOR                              -5-
<PAGE>   6
Option is exercised has been received by the Company. Full payment may consist
of any consideration and method of payment allowable under Section 7(c) of the
Plan. Until the issuance (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a stockholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. A share certificate for the number
of Shares so acquired shall be issued to the Optionee as soon as practicable
after exercise of the Option. No adjustment will be made for a dividend or other
right for which the record date is prior to the date the stock certificate is
issued, except as provided in Section 10 of the Plan.

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

                  (b) TERMINATION OF CONTINUOUS STATUS AS A DIRECTOR. If an
Outside Director ceases to serve as a Director, he or she may, but only within
ninety (90) days after the date he or she ceases to be a Director of the
Company, exercise his or her Option to the extent that he or she was entitled to
exercise it at the date of such termination. Notwithstanding the foregoing, in
no event may the Option be exercised after its term set forth in Section 4(c)
has expired. To the extent that such Outside Director was not entitled to
exercise an Option at the date of such termination, or does not exercise such
Option (to the extent he or she was entitled to exercise) within the time
specified above, the Option shall terminate and the Shares underlying the
unexercised portion of the Option shall revert to the Plan.

                  (c) DISABILITY OF OPTIONEE. Notwithstanding Section 8(b)
above, in the event a Director is unable to continue his or her service as a
Director with the Company as a result of his or her total and permanent
disability (as defined in Section 22(e)(3) of the Code), he or she may, but only
within twelve (12) months from the date of such termination, exercise his or her
Option to the extent he or she was entitled to exercise it at the date of such
termination. Notwithstanding the foregoing, in no event may the Option be
exercised after its term set forth in Section 4(c) has expired. To the extent
that he or she was not entitled to exercise the Option at the date of
termination, or if he or she does not exercise such Option (to the extent he or
she was entitled to exercise) within the time specified above, the Option shall
terminate and the Shares underlying the unexercised portion of the Option shall
revert to the Plan.

                  (d) DEATH OF OPTIONEE. In the event of the death of an
Optionee: (A) during the term of the Option who is, at the time of his or her
death, a Director of the Company and who shall have been in Continuous Status as
a Director since the date of grant of the Option, or (B) three (3) months after
the termination of Continuous Status as a Director, the Option may be exercised,
at any time within twelve (12) months following the date of death, by the
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
had accrued at the date of death or the date of termination, as applicable.
Notwithstanding the foregoing, in no event may the Option be exercised after its
term set forth in Section 4(c) has expired. To the extent that an Optionee was
not entitled to exercise the Option at the date of death or termination or if he
or she does not

DIRECTOR                              -6-
<PAGE>   7
exercise such Option (to the extent he or she was entitled to exercise) within
the time specified above, the Option shall terminate and the Shares underlying
the unexercised portion of the Option shall revert to the Plan.

         9. NONTRANSFERABILITY OF OPTIONS. The Option may not be sold, pledged,
assigned, hypothecated, transferred or disposed of in any manner other than by
will or by the laws of descent or distribution or pursuant to a qualified
domestic relations order (as defined by the Code or the rules thereunder). The
designation of a beneficiary by an Optionee does not constitute a transfer. An
Option may be exercised during the lifetime of an Optionee only by the Optionee
or a transferee permitted by this Section.

         10. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS.

                  (a) ADJUSTMENT. Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, the number of Shares of Common Stock set forth in
Sections 4(b) above, and the number of Shares of Common Stock which have been
authorized for issuance under the Plan but as to which no Options have yet been
granted or which have been returned to the Plan upon cancellation or expiration
of an Option, as well as the price per Share of Common Stock covered by each
such outstanding Option, shall be proportionately adjusted for any increase or
decrease in the number of issued Shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock (including any such change in the number of Shares of Common
Stock effected in connection with a change in domicile of the Company) or any
other increase or decrease in the number of issued Shares of Common Stock
effected without receipt of consideration by the Company; provided however that
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." Such adjustment shall be
made by the Board, whose determination in that respect shall be final, binding
and conclusive. Except as expressly provided herein, no issuance by the Company
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares of Common Stock subject to an
Option.


                  (b) CORPORATE TRANSACTIONS; CHANGE OF CONTROL. In the event of
a Corporate Transaction, each outstanding Option shall be assumed or an
equivalent option shall be substituted by the successor corporation or a Parent
or Subsidiary of such successor corporation, unless the successor corporation
does not agree to assume the outstanding Options or to substitute equivalent
options, in which case the Options shall terminate upon the consummation of the
transaction.


                  For purposes of this Section 10(b), an Option shall be
considered assumed, without limitation, if, at the time of issuance of the stock
or other consideration upon such Corporate Transaction or Change of Control,
each Optionee would be entitled to receive upon

DIRECTOR                              -7-
<PAGE>   8
exercise of an Option the same number and kind of shares of stock or the same
amount of property, cash or securities as the Optionee would have been entitled
to receive upon the occurrence of such transaction if the Optionee had been,
immediately prior to such transaction, the holder of the number of Shares of
Common Stock covered by the Option at such time (after giving effect to any
adjustments in the number of Shares covered by the Option as provided for in
this Section 10); provided however that if such consideration received in the
transaction was not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon exercise of the Option to be
solely common stock of the successor corporation or its Parent equal to the Fair
Market Value of the per Share consideration received by holders of Common Stock
in the transaction.

                  (c) CERTAIN DISTRIBUTIONS. In the event of any distribution to
the Company's stockholders of securities of any other entity or other assets
(other than dividends payable in cash or stock of the Company) without receipt
of consideration by the Company, the Administrator may, in its discretion,
appropriately adjust the price per Share of Common Stock covered by each
outstanding Option to reflect the effect of such distribution.

         11. TIME OF GRANTING OPTIONS. The date of grant of an Option shall, for
all purposes, be the date determined in accordance with Section 4(b) hereof.
Notice of the determination shall be given to each Outside Director to whom an
Option is so granted within a reasonable time after the date of such grant.

         12.      AMENDMENT AND TERMINATION OF THE PLAN.

                  (a) AMENDMENT AND TERMINATION. The Board may amend or
terminate the Plan from time to time in such respects as the Board may deem
advisable; provided that, to the extent necessary and desirable to comply with
Rule 16b-3 under the Exchange Act (or any other applicable law or regulation),
the Company shall obtain approval of the stockholders of the Company to Plan
amendments to the extent and in the manner required by such law or regulation.

                  (b) EFFECT OF AMENDMENT OR TERMINATION. Any such amendment or
termination of the Plan that would impair the rights of any Optionee shall not
affect Options already granted to such Optionee and such Options shall remain in
full force and effect as if this Plan had not been amended or terminated, unless
mutually agreed otherwise between the Optionee and the Board, which agreement
must be in writing and signed by the Optionee and the Company.

         13. CONDITIONS UPON ISSUANCE OF SHARES. Notwithstanding any other
provision of the Plan or any agreement entered into by the Company pursuant to
the Plan, the Company shall not be obligated, and shall have no liability for
failure, to issue or deliver any Shares under the Plan unless such issuance or
delivery would comply with the legal requirements relating to the administration
of stock option plans under applicable U.S. state corporate laws, U.S. federal
and applicable state securities laws, the Code, any stock exchange or Nasdaq
rules or regulations to which the Company may be subject and the applicable laws
of any other country or jurisdiction

DIRECTOR                              -8-
<PAGE>   9
where Options are granted under the Plan, as such laws, rules, regulations and
requirements shall be in place from time to time (the "Applicable Laws"). Such
compliance shall be determined by the Company in consultation with its legal
counsel.

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

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

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

         16. STOCKHOLDER APPROVAL. If required by the Applicable Laws,
continuance of the Plan shall be subject to approval by the stockholders of the
Company. Such stockholder approval shall be obtained in the manner and to the
degree required under the Applicable Laws.

DIRECTOR

         By your signature and the signature of the Company's representative
below, you and the Company agree that this option is granted under and governed
by the terms and conditions of the 1999 Directors' Stock Option Plan and the
Nonstatutory Stock Option Agreement, all of which are attached and made a part
of this document.

OPTIONEE:                                    PERSISTENCE SOFTWARE, INC.

                       NONSTATUTORY STOCK OPTION AGREEMENT



         1. GRANT OF OPTION. The Board of Directors of the Company hereby grants
to the Optionee named in the Notice of Stock Option Grant attached as Part I of
this Agreement (the "Optionee"), an option (the "Option") to purchase a number
of Shares, as set forth in the Notice of Stock Option Grant, at the exercise
price per share set forth in the Notice of Stock Option Grant (the "Exercise
Price"'), subject to the terms and conditions of the 1999 Directors' Stock
Option Plan (the "Plan"), which is incorporated herein by reference.
(Capitalized terms not defined herein shall have the meanings ascribed to such
terms in the Plan.) In the event of a conflict between the terms and conditions
of the Plan and the terms and conditions of this Nonstatutory Stock Option
Agreement, the terms and conditions of the Plan shall prevail.

         2.       EXERCISE OF OPTION.

                  (a) RIGHT TO EXERCISE. This Option is exercisable during its
term in accordance with the Vesting Schedule set out in the Notice of Stock
Option Grant and the applicable provisions of the Plan and this Nonstatutory
Stock Option Agreement. In the event of Optionee's death, disability or other
termination of Optionee's employment or consulting relationship, the
exercisability of the Option is governed by the applicable provisions of the
Plan and this Nonstatutory Stock Option Agreement.

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

                  No Shares shall be issued pursuant to the exercise of this
Option unless such issuance and exercise complies with all relevant provisions
of law and the requirements of any stock exchange or quotation service upon
which the Shares are then listed. Assuming such compliance, for income tax
purposes the Exercised Shares shall be considered transferred to the Optionee on
the date the Option is exercised with respect to such Exercised Shares.

         3. METHOD OF PAYMENT. Payment of the aggregate Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

                  (a)      cash;

DIRECTOR
<PAGE>   13
                  (b)      check;

                  (c) delivery of a properly executed exercise notice together
with such other documentation as the Administrator and the broker, if
applicable, shall require to effect an exercise of the Option and delivery to
the Company of the sale or loan proceeds required to pay the exercise price; or

                  (d) surrender of other Shares which (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares.

         4.       SUSPENSION OR TERMINATION OF OPTION.

                  (a) MISCONDUCT. If the Chief Executive Officer or his or her
designee reasonably believes that an Optionee has committed an act of
misconduct, such officer may suspend the Optionee's right to exercise any option
pending a determination by the Board (excluding the Outside Director accused of
such misconduct). If the Board (excluding the Outside Director accused of such
misconduct) determines an Optionee has committed an act of embezzlement, fraud,
dishonesty, nonpayment of an obligation owed to the Company, breach of fiduciary
duty or deliberate disregard of the Company rules resulting in loss, damage or
injury to the Company, or if an Optionee makes an unauthorized disclosure of any
Company trade secret or confidential information, engages in any conduct
constituting unfair competition, induces any Company customer to breach a
contract with the Company or induces any principal for whom the Company acts as
agent to terminate such agency relationship, neither the Optionee nor his or her
estate shall be entitled to exercise any Option whatsoever. In making such
determination, the Board of Directors (excluding the Outside Director accused of
such misconduct) shall act fairly and shall give the Optionee an opportunity to
appear and present evidence on Optionee's behalf at a hearing before the Board
or a committee of the Board.

                  (b) TERMINATION OF CONTINUOUS STATUS AS A DIRECTOR. If an
Outside Director ceases to serve as a Director, he or she may, but only within
ninety (90) days after the date he or she ceases to be a Director of the
Company, exercise his or her Option to the extent that he or she was entitled to
exercise it at the date of such termination. Notwithstanding the foregoing, in
no event may the Option be exercised after its Expiration Date set forth in the
Notice of Stock Option Grant. To the extent that such Outside Director was not
entitled to exercise an Option at the date of such termination, or does not
exercise such Option (to the extent he or she was entitled to exercise) within
the time specified above, the Option shall terminate and the Shares underlying
the unexercised portion of the Option shall revert to the Plan.

                  (c) DISABILITY OF OPTIONEE. Notwithstanding Section 4(b)
above, in the event a Director is unable to continue his or her service as a
Director with the Company as a result of his or her total and permanent
disability (as defined in Section 22(e)(3) of the Code), he or she may, but only
within twelve (12) months from the date of such termination, exercise his or her
Option to the extent he or she was entitled to exercise it at the date of such
termination. Notwithstanding the foregoing, in no event may the Option be
exercised after its Expiration Date

DIRECTOR                              -2-
<PAGE>   14
set forth in the Notice of Stock Option Grant. To the extent that he or she was
not entitled to exercise the Option at the date of termination, or if he or she
does not exercise such Option (to the extent he or she was entitled to exercise)
within the time specified above, the Option shall terminate and the Shares
underlying the unexercised portion of the Option shall revert to the Plan.

                  (d) DEATH OF OPTIONEE. In the event of the death of an
Optionee:

                           (i) During the term of the Option who is, at the time
of his or her death, a Director of the Company and who shall have been in
Continuous Status as a Director since the date of grant of the Option, the
Option may be exercised, at any time within twelve (12) months following the
date of death, by the Optionee's estate or by a person who acquired the right to
exercise the Option by bequest or inheritance, but only to the extent of the
right to exercise that would have accrued had the Optionee continued living and
remained in Continuous Status as Director for six (6) months after the date of
death. Notwithstanding the foregoing, in no event may the Option be exercised
after its Expiration Date set forth in the Notice of Stock Option Grant.

                           (ii) Within three (3) months after the termination of
Continuous Status as a Director, the Option may be exercised, at any time within
twelve (12) months following the date of death, by the Optionee's estate or by a
person who acquired the right to exercise the Option by bequest or inheritance,
but only to the extent of the right to exercise that had accrued at the date of
termination. Notwithstanding the foregoing, in no event may the option be
exercised after its Expiration Date set forth in the Notice of Stock Option
Grant.

                  To the extent that an Optionee was not entitled to exercise
the Option at the date of death or termination, as provided in Section 4(d)(i)
or (ii) above, or if he or she does not exercise such Option (to the extent he
or she was entitled to exercise) within the time specified above, the Option
shall terminate and the Shares underlying the unexercised portion of the Option
shall revert to the Plan.

         5. NON-TRANSFERABILITY OF OPTION. This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution or
pursuant to a domestic relations order (as defined by the Code or the rules
thereunder) and may be exercised during the lifetime of Optionee only by the
Optionee or a transferee permitted by Section 9 of the Plan. The terms of the
Plan and this Nonstatutory Stock Option Agreement shall be binding upon the
executors, administrators, heirs, successors and assigns of the Optionee.

         6. TERM OF OPTION. This Option may be exercised only within the term
set out in the Notice of Stock Option Grant, and may be exercised during such
term only in accordance with the Plan and the terms of this Nonstatutory Stock
Option Agreement.

         7. TAX CONSEQUENCES. Set forth below is a brief summary of certain
federal tax consequences relating to this Option under the law in effect as of
the date of grant. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND
REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT HIS OR

DIRECTOR                              -3-
<PAGE>   15
HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

                  (a) EXERCISING THE OPTION. Since this Option does not qualify
as an incentive stock option under Section 422 of the Code, the Optionee may
incur regular federal (and state) income tax liability upon exercise. The
Optionee will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess, if any, of the fair market value
of the Exercised Shares on the date of exercise over their aggregate Exercise
Price.

                  (b) DISPOSITION OF SHARES. If the Optionee holds the Option
Shares for more than one year, gain realized on disposition of the Shares will
be treated as long-term capital gain for federal income tax purposes. The
long-term capital gain will be taxed for federal income tax and purposes at a
maximum rate of 20% if the Shares are held more than one year after exercise.

         By your signature and the signature of the Company's representative
below, you and the Company agree that this Option is granted under and governed
by the terms and conditions of the Plan and this Nonstatutory Stock Option
Agreement. Optionee has reviewed the Plan and this Nonstatutory Stock Option
Agreement in their entirety, has had an opportunity to obtain the advice of
counsel prior to executing this Nonstatutory Stock Option Agreement and fully
understands all provisions of the Plan and Nonstatutory Stock Option Agreement.
Optionee hereby agrees to accept as binding, conclusive and final all decisions
or interpretations of the Administrator upon any questions relating to the Plan
and Nonstatutory Stock Option Agreement.
