                                  THE COMPANY
 
  Artisan is a leading developer of high performance, low power and high
density embedded memory and other IP components for the design and manufacture
of complex ICs. The Company offers highly differentiated memory, standard cell
and I/O components that meet the acute needs of complex System-on-a-Chip ICs
for performance, power and density. The Company's products are optimized for
each customer's manufacturing process and are delivered ready for use with
industry standard and proprietary IC design tools. Artisan's objective is to
be the leading supplier of high performance IP components to the semiconductor
market by (i) focusing on key IP components for high volume System-on-a-Chip
ICs, (ii) targeting leading semiconductor manufacturers, (iii) generating
revenue through an innovative business model, (iv) proliferating its IP
components throughout customer ICs, (v) leveraging its product development
process and (vi) maintaining its technological leadership. The Company
licenses its products to semiconductor manufacturers and fabless semiconductor
companies for the design of ICs used in complex, high volume applications,
such as portable computing devices, cellular phones, consumer multimedia
products, automotive electronics, personal computers and workstations.
 
  The development of the merchant IP component market has resulted from the
continuing trend toward horizontal specialization in the semiconductor
industry, a trend that has been driven by a growth in manufacturing capacity
and an increasing focus on core competencies. Semiconductor manufacturers are
continuing to focus on semiconductor design and manufacturing processes and
are beginning to outsource the design of particular IP components critical to
the successful development of complex System-on-a-Chip ICs. This trend favors
the emergence of a substantial merchant IP component market that is estimated
by industry sources to grow from approximately $600 million in 1997 to
approximately $2.0 billion in the year 2001. In addition, advances in
semiconductor manufacturing processes have made it possible to place
approximately 40 million transistors on a single IC, a number that is widely
expected to increase to nearly 100 million transistors by the end of the
decade. Each of these transistors must be individually designed and tested
and, consequently, the gap is increasing between what can be manufactured and
what can be designed within the time to market requirements of the
semiconductor manufacturer.
 
  Artisan provides high performance and low power embedded memory, standard
cell and I/O components customized to each customer's manufacturing process.
Together, these components constitute approximately 80% of the silicon area on
a typical System-on-a-Chip IC. Improvements in the performance of these
components, particularly memory, can have a significant impact on the overall
performance of the IC. The Company's IP components are designed to offer
semiconductor manufacturers high performance, cost effective solutions that
reduce the time required to bring new ICs to market. The Company believes that
it provides the fastest memory products and the most dense standard cell
products currently available in the merchant IP component market.
 
  The Company primarily licenses its products on a nonexclusive, worldwide
basis to major semiconductor manufacturers and grants these manufacturers the
right to distribute its IP components freely to their internal design teams
and to fabless semiconductor companies that manufacture at the same facility.
The Company believes that this licensing approach encourages proliferation of
the Company's products and provides a highly efficient distribution channel
for its IP components. The Company's revenue increased from $2.7 million in
fiscal 1995 to $4.1 million in fiscal 1996 and to $8.9 million in fiscal 1997,
representing a compound annual growth rate of 81.4% over this two year period.
Artisan has licensed its products to many leading semiconductor manufacturers
including Chartered Semiconductor Manufacturing, Inc. ("Chartered"), Fujitsu
Microelectronics, Inc. ("Fujitsu"), GEC Plessey Semiconductor Ltd. ("GEC
Plessey"), NEC Electronics, Inc. ("NEC"), OKI Electric Industry Co., Ltd.
("OKI"), SGS-THOMSON MICROELECTRONICS S.r.l. ("SGS-THOMSON"), Toshiba
International Corporation ("Toshiba") and VLSI Technology, Inc. ("VLSI
Technology").
 
  The Company was incorporated in California in April 1991 as VLSI Libraries
Incorporated and changed its name to Artisan Components, Inc. in March 1997.
The Company anticipates that it will reincorporate in Delaware prior to the
completion of this Offering. The Company's principal executive offices are

                                 RISK FACTORS
 
  An investment in the shares of Common Stock offered hereby involves a high
degree of risk. In addition to the other information in this Prospectus, the
following risk factors should be considered carefully in evaluating an
investment in the Common Stock offered by this Prospectus. When used in this
Prospectus, the words "expects," "anticipates," "estimates" and similar
expressions are intended to identify forward looking statements. Such
statements are subject to risks and uncertainties that could cause actual
results to differ materially from those projected. These risks and
uncertainties include, but are not limited to, those risks discussed below and
elsewhere in this Prospectus. Actual results could differ materially from
those projected in the forward looking statements as a result of the risk
factors discussed below and elsewhere in this Prospectus.
 
  FLUCTUATIONS IN OPERATING RESULTS. The Company's operating results have
fluctuated in the past as a result of a number of factors including the
relatively large size and small number of customer orders during a given
period; the timing of customer orders; delays in the design process due to
changes by a customer to its order after it is placed; the Company's ability
to achieve progress on percentage of completion contracts; the length of the
Company's sales cycle; the Company's ability to develop, introduce and market
new products and product enhancements; the timing of new product announcements
and introductions by the Company and its competitors; market acceptance of the
Company's products; the demand for semiconductors and end user products that
incorporate semiconductors; and general economic conditions. The Company's
future operating results may fluctuate from quarter to quarter and on an
annual basis as a result of these and other factors, in particular the
relatively large size and small number of customer orders during a given
period and the rate of royalties recognized in a given period. Accordingly, it
is likely that in some future quarter the Company's operating results will be
below the expectations of public market analysts and investors. In such event,
the price of the Company's Common Stock would likely decline, perhaps
substantially.
 
  Revenue in any quarter is dependent on a number of factors, and is not
predictable with any degree of certainty. Since the Company's expense levels
are based in part on management's expectations regarding future revenue, if
revenue is below expectations in any quarter, the adverse effect may be
magnified by the Company's inability to adjust spending in a timely manner to
compensate for any revenue shortfall. The Company also intends to increase its
sales and marketing expenses in an attempt to broaden its market coverage. The
Company's costs and expenses will be based in part on the Company's
expectations of future revenue from product licenses. Accordingly, if the
Company does not realize its expected revenue, its business, operating results
and financial condition could be materially adversely affected.
 
  The Company's sales cycle can be lengthy and is subject to a number of risks
over which the Company has little or no control. As a result of the
significant dollar amounts represented by a single customer order, the timing
of the receipt of an order can have a significant impact on the Company's
revenue for a particular period. In addition, because the Company's revenue is
concentrated among a small number of customers, a decline or a delay in the
recognition of revenue from one customer in a period may cause the Company's
business, operating results and financial condition in such period to be
materially adversely affected and may lead to significant fluctuations from
quarter to quarter. Any significant or ongoing failure to obtain new orders
from customers would have a material adverse effect on the Company's business,
operating results and financial condition.
 
  To date, a substantial majority of the Company's revenue has been recognized
on a percentage of completion method. Provisions for estimated losses on the
uncompleted contracts are recognized in the period in which the likelihood of
such losses is determined. As
 
                                       5
<PAGE>
 
the completion period ranges from three to six months, the revenue in any
quarter is dependent on the Company's progress toward completion of the
project. There can be no assurance that the Company's estimates will be
accurate, and, in the event they are not, the Company's business, operating
results and financial condition in subsequent periods could be materially
adversely affected. The Company has in the past experienced delays in the
progress of certain projects, and there can be no assurance that such delays
will not occur in the future. Any delay or failure to achieve such progress
could result in damage to customer relationships and the Company's reputation,
under-utilization of engineering resources or a delay in the market acceptance
of the Company's products, any of which could have a material adverse effect
on the Company's business, operating results and financial condition. In
addition, the Company's contracts with customers generally may be canceled
without cause, and, if a customer cancels or delays performance under any such
contracts, the Company's business, operating results and financial condition
could be materially adversely affected. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
  DEPENDENCE ON EMERGENCE OF MERCHANT IP COMPONENT MARKET AND BROAD MARKET
ACCEPTANCE OF THE COMPANY'S PRODUCTS. The market for merchant IP components
has only recently begun to emerge. The Company's ability to achieve sustained
revenue growth and profitability in the future will depend on the continued
development of this market and, to a large extent, on the demand for System-
on-a-Chip ICs. There can be no assurance that the merchant IP component and
System-on-a-Chip markets will continue to develop or grow at a rate sufficient
to support the Company's business. If either of these markets fails to grow or
develops slower than expected, the Company's business, operating results and
financial condition would be materially adversely affected. To date, the
Company's IP products have been licensed only by a limited number of
customers. The vast majority of the Company's existing and potential customers
currently rely on components developed internally and/or by other vendors. The
Company's future growth, if any, is dependent on the adoption of, and
increased reliance on, merchant IP components by both existing and potential
customers. Moreover, if the Company's products do not achieve broad market
acceptance, the Company's business, operating results and financial condition
would be materially adversely affected.
 
  COMPETITION. The Company's strategy of targeting semiconductor manufacturers
that participate in, or may enter, the System-on-a-Chip market requires the
Company to compete in intensely competitive markets. Within the merchant
segment of the IP component market, the Company competes primarily against
Aspec Technology, Inc. ("Aspec"), Avant! Corporation ("Avant!"), Cascade
Design Automation Inc., a subsidiary of OKI ("Cascade Design"), Mentor
Graphics Corporation ("Mentor Graphics"), and the Silicon Architects group of
Synopsys, Inc. ("Synopsys"). In addition, the Company may face competition
from consulting firms and companies that typically have operated in the
generic library segment of the IP market and that now seek to offer customized
IP components as enhancements to their generic solutions. The Company also
faces significant competition from the internal design groups of the
semiconductor manufacturers that are expanding their manufacturing
capabilities and portfolio of IP components to participate in the System-on-a-
Chip market. These internal design groups compete with the Company for access
to the parent's IP component requisitions and may eventually compete with the
Company to supply IP components to third parties on a merchant basis. There
can be no assurance that internal design groups will not expand their product
offerings to compete directly with those of the Company or will not actively
seek to participate as merchant vendors in the IP component market by selling
to third party semiconductor manufacturers or, if they do, that the Company
will be able to compete against them successfully. In addition to competition
from companies in the merchant IP component market, the Company faces
competition from vendors that supply electronic design automation ("EDA")
software tools, including certain of those mentioned above, and there can be
no assurance that the Company will be able to compete successfully against
them.
 
                                       6
<PAGE>
 
  The Company expects competition to increase in the future from existing
competitors and from new market entrants with products that may be less
expensive than the Company's IP components or that may provide better
performance or additional features not currently provided by the Company. Many
of the Company's current and potential competitors have substantially greater
financial, technical, manufacturing, marketing, distribution and other
resources, greater name recognition and market presence, longer operating
histories, lower cost structures and larger customer bases than the Company.
As a result, they may be able to adapt more quickly to new or emerging
technologies and changes in customer requirements. In addition, certain of the
Company's principal competitors offer a single vendor solution, since, in the
case of EDA tools companies, they maintain their own EDA design tools and IP
libraries or, in the case of internal design groups, they provide IP
components developed to utilize the qualities of a given manufacturing
process, and may therefore benefit from certain capacity, cost and technical
advantages. The Company's ability to compete successfully in the emerging
market for IP components will depend upon certain factors, many of which are
beyond the Company's control including, but not limited to, success in
designing new products; implementing new designs at smaller process
geometries; access to adequate EDA tools (many of which are licensed from the
Company's current or potential competitors); the price, quality and timing of
new product introductions by the Company and its competitors; the emergence of
new IP component interchangeability standards; the widespread licensing of IP
components by semiconductor manufacturers or their design groups to third
party manufacturers; the ability of the Company to protect its intellectual
property; market acceptance of the Company's IP components; success of
competitive products; market acceptance of products using System-on-a-Chip
ICs; and industry and general economic conditions. There can be no assurance
that the Company will be able to compete successfully in the emerging merchant
IP component market. See "Business--Competition."
 
  DEPENDENCE ON SEMICONDUCTOR MANUFACTURERS; DEPENDENCE ON SEMICONDUCTOR AND
ELECTRONICS INDUSTRIES. The Company's success is substantially dependent both
on the adoption of the Company's technology by semiconductor manufacturers and
on an increasing demand for products requiring complex System-on-a-Chip ICs,
such as portable computing devices, cellular phones, consumer multimedia
products, automotive electronics, personal computers and workstations. The
Company is subject to many risks beyond its control that influence the success
of its customers, including, among others, competition faced by each customer
in its particular industry, market acceptance of the customer's products that
incorporate the Company's technology, the engineering, sales and marketing
capabilities of the customer, and the financial and other resources of the
customer.
 
  The semiconductor and electronics products industries are characterized by
rapid technological change, frequent introductions of new products, short
product life cycles, fluctuations in manufacturing capacity and pricing and
gross margin pressures. Each of these industries is highly cyclical and has
periodically experienced significant downturns, often in connection with or in
anticipation of declines in general economic conditions during which the
number of new IC design projects often decreases. Revenue from licenses of the
Company's products is influenced by the level of design efforts by its
customers and factors negatively affecting these industries could have a
material adverse effect on the Company's business, operating results and
financial condition. The Company's business, operating results and financial
condition may fluctuate in the future from period to period as a consequence
of general economic conditions in the semiconductor and electronics
industries.
 
  DEPENDENCE ON NEW BUSINESS MODEL. The Company has historically generated
revenue from license fees. Beginning in late fiscal 1996, however, the Company
began implementation of a royalty based business model that is intended to
generate revenue from both license fees
 
                                       7
<PAGE>
 
and future royalties. The Company is still in the process of implementing this
royalty based business model and, to date, has had only limited success with
its introduction. Certain of the Company's customers, including some of its
largest customers, have initially resisted the adoption of the royalty based
model. There can be no assurance that the Company will be able to complete the
implementation of the royalty based model successfully, or that, when fully
implemented, this model will have the anticipated benefits. The failure of the
Company to implement its new business model successfully could have a material
adverse effect on the Company's business, operating results and financial
condition. To date, the Company has received no royalty revenue, and it does
not anticipate receiving any prior to fiscal 1999. There can be no assurance
that the Company will ever receive any royalty revenue or that, if it does,
the amount will be significant. See "--Dependence on Semiconductor
Manufacturers; Dependence on Semiconductor and Electronics Industries" and "--
Customer Concentration; Limited Customer Base."
 
  The Company believes that its long term success will be substantially
dependent on future royalties. However, even if the Company successfully
implements its new business model, the Company will face risks inherent in
such a model. In particular, the Company's ability to forecast royalty revenue
will be limited by factors that are beyond the Company's ability to control or
assess in advance. Royalties, if any, will be recognized in the quarter in
which the Company receives a royalty report from its customers and will be
dependent upon fluctuating sales volumes. In addition, under the royalty based
business model, the Company's revenue will be dependent upon the sales by its
customers of products that incorporate the Company's technology. Even if the
Company's technology is adopted, there can be no assurance that it will be
used in a product that is ultimately brought to market, achieves commercial
acceptance or results in significant royalties to the Company. The Company
will also face risks relating to the accuracy and completeness of the royalty
collection process. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
  CUSTOMER CONCENTRATION; LIMITED CUSTOMER BASE. The Company has been
dependent on a relatively small number of customers for a substantial portion
of its annual revenue, although the customers comprising this group have
changed from time to time. In fiscal 1995, SGS-THOMSON, NEC, the United States
Department of Defense (the "DOD"), Samsung Corporation ("Samsung") and LSI
Logic Corporation ("LSI Logic") accounted for 20%, 17%, 17%, 11% and 10% of
revenue, respectively. In fiscal 1996, ATI Technologies, Inc. ("ATI"), SGS-
THOMSON, OKI and the DOD accounted for 37%, 20%, 15% and 10% of revenue,
respectively. In fiscal 1997, SGS-THOMSON, Fujitsu, OKI and NEC accounted for
27%, 24%, 16% and 13% of revenue, respectively. The Company anticipates that
its revenue will continue to depend on a limited number of major customers for
the foreseeable future, although the companies considered to be major
customers and the percentage of revenue represented by each major customer may
vary from period to period depending on the addition of new contracts and the
number of designs utilizing the Company's products. None of the Company's
customers has a written agreement with the Company that obligates it to
license future generations of products or new products, and there can be no
assurance that any customer will license IP components from the Company in the
future. In addition, there can be no assurance that any of the Company's
customers will ship products incorporating the Company's technology or that,
if such shipments occur, they will generate significant revenue. The loss of
one or more of the Company's major customers, reduced orders by one or more of
such customers or the failure of a customer to ship products containing the
Company's IP components could materially adversely affect the Company's
business, operating results and financial condition. See "Business--
Customers."
 
  The Company faces numerous risks in successfully obtaining orders from
customers on terms consistent with the Company's business model, including,
among others, the lengthy and
 
                                       8
<PAGE>
 
expensive process of building a relationship with a potential customer before
reaching an agreement with such party to license the Company's products;
persuading large semiconductor manufacturers to work with, to rely for
critical technology on, and to disclose proprietary information to, a smaller
company, such as the Company; and persuading potential customers to bear
certain development costs associated with development of customized
components. There are a relatively limited number of semiconductor
manufacturers to which the Company can license its technology in a manner
consistent with its business model and there can be no assurance that such
manufacturers will rely on merchant IP components or adopt the Company's
products. See "--Competition" and "Business--Customers."
 
  PRODUCT CONCENTRATION. The Company derives substantially all of its revenue
from sales of its memory and standard cell products that, together, accounted
for 83%, 79% and 94% of revenue in fiscal 1995, 1996 and 1997, respectively.
The Company expects that memory products, in combination with standard cell
products, will continue to account for a significant portion of the Company's
revenue, for the foreseeable future. There can be no assurance that the
Company will continue to derive revenue from memory or standard cell products
and a decline in revenue from such products would have a material adverse
effect on the Company's business, operating results and financial condition.
The Company's future financial performance will depend in significant part on
the successful development, introduction and customer acceptance of new
products. See "--New Product Development and Technological Change."
 
  LENGTHY SALES CYCLE AND DESIGN PROCESS. The license of the Company's
products typically involves a significant commitment of capital by the
customer and a purchase will often be timed to coincide with a customer's
migration to a new manufacturing process. Potential customers generally commit
significant resources to an evaluation of available IP solutions and require
the Company to expend substantial time, effort and resources to educate them
about the value of the Company's products. A variety of factors, including
factors over which the Company has little or no control, may cause potential
customers to favor an alternate solution or to delay or forego a license of
the Company's products. As a result of these and other factors, the sales
cycle for the Company's products is long, typically ranging from six to 12
months. The Company's ability to forecast the timing and scope of specific
sales is limited, and delay of or failure to complete one or more large
contracts could have a material adverse effect on the Company's business,
operating results and financial condition and could cause the Company's
operating results to fluctuate significantly from quarter to quarter.
 
  Once the Company receives and accepts an order from a customer, the Company
must commit significant resources to customizing its products for the
customer's manufacturing process. This customization is complex and time
consuming and is subject to a number of risks over which the Company has
little or no control, including the customer's adjustments and alterations of
its manufacturing process or the timing of migration to a new process.
Typically, this customization takes from three to six months to complete.
Delays in product customization could have a material adverse effect on the
Company's business, operating results and financial condition and could cause
the Company's operating results to vary significantly from quarter to quarter.
 
  RISKS ASSOCIATED WITH INTERNATIONAL CUSTOMERS. A substantial portion of the
Company's revenue is derived from customers outside the United States. In
fiscal 1995, 1996 and 1997, revenue derived from customers outside the United
States, primarily in Asia and Europe, represented approximately 55%, 47% and
67%, respectively, of the Company's revenue. The Company anticipates that
international revenue will remain a substantial portion of revenue in the
future. To date, all of the revenue from international customers has been
denominated in U.S. dollars. In the event that the Company's competitors
denominate their sales in a currency that becomes relatively inexpensive in
comparison to the U.S. dollar, the Company may
 
                                       9
<PAGE>
 
experience fewer orders from international customers whose business is based
primarily on the less expensive currency. The Company intends to continue to
expand its sales and marketing activities in Asia and Europe. The Company's
expansion of its international business involves a number of risks including
the impact of possible recessionary environments in economies outside the
United States; political and economic instability; exchange rate fluctuations;
longer accounts receivable collection periods; greater difficulty in accounts
receivable collection; unexpected changes in regulatory requirements; reduced
or limited protection for intellectual property rights; export license
requirements; tariffs and other trade barriers and potentially adverse tax
consequences. There can be no assurance that the Company will be able to
sustain or increase revenue derived from international customers or that the
foregoing factors will not have a material adverse effect on the Company's
business, operating results and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business--Sales, Marketing and Distribution."
 
  NEW PRODUCT DEVELOPMENT AND TECHNOLOGICAL CHANGE. The Company's customers
compete in the semiconductor industry, which is subject to rapid technological
change, frequent introductions of new products, short product life cycles,
changes in customer demands and requirements and evolving industry standards.
The development of new manufacturing processes, the introduction of products
embodying new technologies and the emergence of new industry standards can
render existing products obsolete and unmarketable. Accordingly, the Company's
future success will depend on its ability to continue to enhance its existing
products and to develop and introduce new products that satisfy increasingly
sophisticated customer requirements and that keep pace with new product
introductions, emerging manufacturing process technologies and other
technological developments in the semiconductor industry. Any failure by the
Company to anticipate or respond adequately to changes in manufacturing
processes or customer requirements, or any significant delays in product
development or introduction, would have a material adverse effect on the
Company's business, operating results and financial condition. There can be no
assurance that the Company will not experience difficulties that could delay
or prevent the successful development, introduction and sale of new or
enhanced products or that such new or enhanced products will achieve market
acceptance. Any delay in release dates of new or enhanced products could
materially adversely affect the Company's business, operating results and
financial condition. The Company could also be exposed to litigation or claims
from its customers in the event that it does not satisfy its delivery
commitments. There can be no assurance that any such claim would not have a
material adverse effect on the Company's business, operating results and
financial condition. See "Business--Product Development."
 
  DEPENDENCE ON KEY PERSONNEL. The Company's success depends in large part on
the continued contributions of its key management, engineering, sales and
marketing personnel, many of whom are highly skilled and would be difficult to
replace. None of the Company's senior management or key technical personnel is
bound by an employment contract. In addition, the Company does not currently
maintain key man life insurance covering its key personnel. The Company
believes that its success depends to a significant extent on the ability of
its management to operate effectively, both individually and as a group.
Certain of the Company's senior management have only recently joined the
Company and there can be no assurance they and other newly hired employees
will be assimilated into the Company successfully. The Company must also
attract and retain highly skilled managerial, engineering, sales and marketing
and finance personnel. Competition for such personnel is intense, and there
can be no assurance that the Company will be successful in attracting and
retaining such personnel. The loss of the services of any of the key
personnel, the inability to attract or retain qualified personnel in the
future or delays in hiring required personnel, particularly engineers, could
have a material adverse effect on the Company's business, operating results
and financial condition. See "Business--Employees" and "Management--Executive
Officers and Directors."
 
                                      10

  MANAGEMENT OF GROWTH. The ability of the Company to license its products and
manage its business successfully in a rapidly evolving market requires an
effective planning and management process. The Company's rapid growth has
placed, and is expected to continue to place, a significant strain on the
Company's managerial, operational and financial resources. From September 30,
1996 to September 30, 1997, the Company grew from 28 to 56 fulltime employees.
The Company's customers rely heavily on the Company's technological expertise
in designing, testing and manufacturing products incorporating the Company's
IP components. Relationships with new customers generally require significant
engineering support. As a result, any increase in the demand for the Company's
products will increase the strain on the Company's personnel, particularly its
engineers. The Company's financial and management controls, reporting systems
and procedures are also limited. Although some new controls, systems and
procedures have been implemented, the Company's future growth, if any, will
depend on its ability to continue to implement and improve operational,
financial and management information and control systems on a timely basis,
together with maintaining effective cost controls and any failure to do so
would have a material adverse effect on the Company's business, operating
results and financial condition. Further, the Company will be required to
manage multiple relationships with various customers and other third parties
and must successfully implement its new business model. There can be no
assurance that the Company's systems, procedures or controls will be adequate
to support the Company's operations or that the Company's management will be
able to achieve the rapid execution necessary to offer its services and
products successfully and to implement its business plan. The Company's
inability to manage any future growth effectively would have a material
adverse effect on the Company's business, operating results and financial
condition. See "Business--Employees" and "Management."
 
  RISKS ASSOCIATED WITH PROTECTION OF INTELLECTUAL PROPERTY. The Company
relies primarily on a combination of nondisclosure agreements and other
contractual provisions and patent, trademark, trade secret and copyright law
to protect its proprietary rights. Failure of the Company to enforce its
patents, trademarks or copyrights or to protect its trade secrets could have a
material adverse effect on the Company's business, operating results and
financial condition. There can be no assurance that such intellectual property
rights can be successfully asserted in the future or will not be invalidated,
circumvented or challenged. From time to time, third parties, including
competitors of the Company, may assert patent, copyright and other
intellectual property rights to technologies that are important to the
Company. There can be no assurance that third parties will not assert
infringement claims against the Company in the future, that assertions by
third parties will not result in costly litigation or that the Company would
prevail in any such litigation or be able to license any valid and infringed
patents from third parties on commercially reasonable terms. Litigation,
regardless of the outcome, could result in substantial cost and diversion of
resources of the Company. Any infringement claim or other litigation against
or by the Company could materially adversely affect the Company's business,
operating results and financial condition.
 
  In certain instances, the Company has elected to rely on trade secret law
rather than patent law to protect its proprietary technology. However, trade
secrets are difficult to protect. The Company seeks to protect its proprietary
technology and processes, in part, by confidentiality agreements with its
employees and customers. There can be no assurance that these contracts will
not be breached, that the Company will have adequate remedies for any breach,
or that the Company's trade secrets will not otherwise become known or be
independently discovered by competitors. In addition, effective trade secret
protection may be unavailable or limited in certain foreign countries.
 
  In addition, there can be no assurance that competitors of the Company, many
of which have substantial resources and have made substantial investments in
competing technologies,
 
                                      11
<PAGE>
 
do not have, or will not seek to apply for and obtain, patents that will
prevent, limit or interfere with the Company's ability to make, use or sell
its products either in the United States or in international markets. There
can be no assurance that the Company will not in the future become subject to
patent infringement claims and litigation or interference proceedings declared
by the United States Patent and Trademark Office ("USPTO") to determine the
priority of inventions. The defense and prosecution of intellectual property
suits, USPTO interference proceedings and related legal and administrative
proceedings are both costly and time consuming. Any such suit or proceeding
involving the Company could have a material adverse effect on the Company's
business, operating results and financial condition. See "Business--Patents
and Intellectual Property Protection."
 
  FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING. The Company intends
to continue to invest heavily in the development of new products and
enhancements to its existing products. The Company's future liquidity and
capital requirements will depend upon numerous factors, including the costs
and timing of expansion of product development efforts and the success of
these development efforts, the costs and timing of expansion of sales and
marketing activities, the extent to which the Company's existing and new
products gain market acceptance, competing technological and market
developments, the costs involved in maintaining and enforcing patent claims
and other intellectual property rights, the level and timing of license
revenue, available borrowings under line of credit arrangements and other
factors. The Company believes that the proceeds from this Offering, together
with the Company's current cash balances and any cash generated from
operations and from available or future debt financing, will be sufficient to
meet the Company's operating and capital requirements for at least the next 12
months. However, there can be no assurance that the Company will not require
additional financing within this time frame. The Company's forecast period of
time through which its financial resources will be adequate to support its
operations implies assumptions about its business that are forward looking and
that involve risks and uncertainties, and actual results could vary. The
factors described in this paragraph will affect both the Company's future
capital requirements and the adequacy of its available funds. The Company may
be required to raise additional funds through public or private financing,
strategic relationships or other arrangements. There can be no assurance that
such funding, if needed, will be available on terms attractive to the Company,
or at all. Furthermore, any additional equity financing may be dilutive to
stockholders, and debt financing, if available, may involve restrictive
covenants. Strategic arrangements, if necessary to raise additional funds, may
require the Company to relinquish its rights to certain of its technologies or
products. The failure of the Company to raise capital when needed could have a
material adverse effect on the Company's business, operating results and
financial condition. See "Use of Proceeds" and "Management's Discussion and
Analysis of Financial Condition and Results of Operation."
 
  NO PRIOR PUBLIC MARKET FOR COMMON STOCK; POTENTIAL VOLATILITY OF STOCK
PRICE. Prior to this Offering, there has been no public market for the
Company's Common Stock, and there can be no assurance that an active public
market will develop or that, if one does develop, it will be maintained. The
initial public offering price, which was determined through negotiations
between the Company and the Underwriters, may not be indicative of the market
price of the Common Stock after the Offering. In addition, the securities
markets have from time to time experienced significant price and volume
fluctuations that are unrelated and disproportionate to the operating
performance of particular companies. The market prices of the common stock of
many publicly traded companies have in the past been, and can in the future be
expected to be, especially volatile. The market price of the Company's Common
Stock is likely to be highly volatile and may be subject to wide fluctuations
in response to announcements of technological innovations or new products by
the Company, its customers or its competitors, release of reports by
securities analysts, developments or disputes concerning patents or
proprietary
 
                                      12
<PAGE>
 
rights, economic and other external factors, as well as period to period
fluctuations in the Company's financial results. See "Underwriting."
 
  CONCENTRATION OF OWNERSHIP. The Company's founders, officers, directors and
their affiliates will, in the aggregate, beneficially own approximately 64.7%
of the Company's outstanding Common Stock following the completion of this
Offering (61.3% if the Underwriters' over-allotment option is exercised in
full). As a result, these stockholders, acting together, would effectively be
able to control substantially all matters requiring approval by the
stockholders, including the election of directors. Such concentration of
ownership may have the effect of delaying, deferring or preventing a change in
control of the Company. See "Principal Stockholders."
 
  CERTAIN ANTI-TAKEOVER PROVISIONS. Upon the closing of this Offering, the
Board of Directors of the Company will have the authority to issue up to
5,000,000 shares of Preferred Stock and to determine the rights, preferences,
privileges and restrictions, including voting rights, of such shares without
any further vote or action by the stockholders. The rights of the holders of
Common Stock will be subject to, and may be adversely affected by, the rights
of the holders of any Preferred Stock that may be issued in the future. The
issuance of Preferred Stock could have the effect of delaying, deferring or
preventing a change in control of the Company. The Company has no current
plans to issue shares of Preferred Stock. In addition, Section 203 of the
Delaware General Corporation Law ("Section 203"") restricts certain business
combinations with any "interested stockholder" as defined by such statute. In
addition, the Company's Certificate of Incorporation and Bylaws that will be
in effect upon the closing of this Offering will contain certain other
provisions that may have the effect of delaying, deferring or preventing a
change of control of the Company including cumulative voting for the election
of directors, the elimination of actions by written consent of stockholders
and the establishment of an advance notice procedure for stockholder proposals
and director nominations to be acted upon at annual meetings of the
stockholders. These provisions are designed to encourage potential acquirors
to negotiate with the Company's Board of Directors and give the Board of
Directors sufficient opportunity to consider various alternatives to maximize
stockholder value. These provisions are also intended to discourage certain
tactics that may be used in proxy contests. However, issuance of Preferred
Stock, charter and bylaw provisions or restrictions from Section 203 could
discourage potential acquisition proposals and could delay or prevent a change
in control of the Company and, as a consequence, they also may adversely
affect the market price of the Company's Common Stock. Such provisions may
also have the effect of preventing changes in the management of the Company.
See "Description of Capital Stock--Preferred Stock."
 
  SHARES ELIGIBLE FOR FUTURE SALE. Sales of a substantial number of shares of
Common Stock in the public market following this Offering could adversely
affect the market price of the Common Stock prevailing from time to time. The
number of shares of Common Stock available for sale in the public market is
limited by restrictions under the Securities Act of 1933, as amended (the
"Securities Act"), and lock-up agreements executed by officers, directors,
optionholders and substantially all stockholders of the Company under which
such security holders have agreed not to sell or otherwise dispose of any of
their shares for a period of 180 days after the date of this Prospectus
without the prior written consent of Deutsche Morgan Grenfell Inc. In addition
to the 2,900,000 shares of Common Stock offered hereby (assuming no exercise
of the Underwriters' over-allotment option), there will be 9,079,953 shares of
Common Stock outstanding as of the date of this Prospectus, all of which are
"restricted" shares under the Securities Act. As a result of the lock-up
agreements described above and the provisions of Rules 144(k), 144 and 701
promulgated under the Securities Act ("Rule 144(k)," "Rule 144" and "Rule
701," respectively), the restricted shares will be available for sale in the
public market as follows: (i) no shares will be eligible for immediate sale on
the date of this Prospectus,
 
                                      13
<PAGE>
 
(ii) approximately 9,029,953 shares will become eligible for sale 180 days
after the date of this Prospectus (assuming no release from the lock-up
agreements) upon expiration of lock-up agreements and (iii) approximately
50,000 shares will become eligible for sale one year after the date of this
Prospectus. After this Offering, the holders of approximately 3,435,736 shares
of Common Stock issuable upon conversion of Preferred Stock or exercise of a
warrant will be entitled to certain demand and piggyback rights with respect to
registration of such shares under the Securities Act. If such holders, by
exercising their demand registration rights, cause a large number of securities
to be registered and sold in the public market, such sales could have an
adverse effect on the market price for the Company's Common Stock. If the
Company were to initiate a registration and include shares held by such holders
pursuant to the exercise of their piggyback registration rights, such sales
might have an adverse effect on the Company's ability to raise capital. See
"Shares Eligible for Future Sale" and "Underwriting."
 
  DISCRETION AS TO USE OF PROCEEDS. Although the Company currently intends to
apply the net proceeds of this Offering in the manner described under "Use of
Proceeds," it has broad discretion within such proposed uses as to the
allocation of the net proceeds, the timing of expenditures and all other
aspects relating to the application of such proceeds. The Company reserves the
right to reallocate the net proceeds of this Offering as management, in its
discretion, deems necessary or advisable. There can be no assurance that the
actual allocation of the Offering proceeds will not differ materially from
their current or anticipated use.
 
  ABSENCE OF DIVIDENDS; IMMEDIATE AND SUBSTANTIAL DILUTION. The Company does
not anticipate paying any dividends in the foreseeable future. See "Dividend
Policy." Investors participating in this Offering will incur immediate and
substantial dilution in the net tangible book value of their shares of Common
Stock. Additional dilution will occur upon the exercise of outstanding stock
options or warrants. See "Dilution."

<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 2,900,000 shares of
Common Stock offered hereby are estimated to be approximately $
(approximately $            if the Underwriters' over-allotment option is
exercised in full), assuming an initial public offering price of $    per
share and after deducting the estimated underwriting discount and offering
expenses. The principal purposes of this Offering are to obtain additional
capital, to create a public market for the Company's Common Stock and to
facilitate future access by the Company to public equity markets.
 
  The Company ultimately expects to use the net proceeds from this Offering
for general corporate purposes, including working capital and capital
expenditures. The Company anticipates spending at least $850,000 for equipment
lease and office lease payments and approximately $3.4 million for capital
expenditures over the next 12 months. As of the date of this Prospectus, the
Company has no specific plans regarding the use of the remainder of the net
proceeds of this Offering. A portion of the proceeds may also be used to
acquire or invest in complementary businesses or products or to obtain the
right to use complementary technologies. Although the Company evaluates such
potential acquisitions from time to time, the Company has no present
understandings, commitments or agreements with respect to any material
acquisitions of other businesses, products or technologies. Pending such uses,
the Company intends to invest the net proceeds received by it from this
Offering in short-term, investment-grade, interest-bearing securities.
 
                                DIVIDEND POLICY
 
  Since March 1996, when the Company converted to a C corporation from a
subchapter S corporation, the Company has not declared or paid any cash
dividends on its Common Stock or other securities. The Company presently
intends to retain future earnings, if any, for use in the operation and
expansion of its business and does not anticipate paying cash dividends in the
foreseeable future.

  The following table sets forth as of September 30, 1997 (i) the actual

Company giving effect to the conversion of all outstanding shares of Preferred
Stock into Common Stock and the issuance of 50,000 shares of Common Stock upon
the exercise of a warrant that expires automatically upon the closing of this
Offering, and (iii) the pro forma capitalization of the Company as adjusted to
give effect to the sale of the 2,900,000 shares of Common Stock offered hereby
at an assumed initial public offering price of $     per share and after
deducting the estimated underwriting discount and offering expenses. This
table should be read in conjunction with the Financial Statements and Notes
thereto and "Management's Discussion and Analysis of Financial Condition and

                                   DILUTION
 
  The net tangible book value of the Company as of September 30, 1997 was $9.3
million, or $1.03 per share of Common Stock. Net tangible book value per share
represents the amount of total tangible assets of the Company less total
liabilities divided by the total number of shares of Common Stock outstanding.
After giving effect to the sale by the Company of the 2,900,000 shares of
Common Stock offered hereby at an assumed initial public offering price of
$      per share (after deducting the estimated underwriting discount and
offering expenses), the adjusted pro forma net tangible book value as of
September 30, 1997 would have been approximately $          , or $      per
share. This represents an immediate increase in net tangible book value per
share of Common Stock of $      to existing stockholders and an immediate
dilution in net tangible book value of $      per share to new investors. The
following table illustrates this per share dilution:

(1) The Company and certain Selling Stockholders have granted the Underwriters
    an option, exercisable within 30 days of the date of this Prospectus, to
    purchase up to an aggregate of 435,000 shares of Common Stock at the
    initial public offering price less the underwriting discount, solely to
    cover over-allotments, if any. In the event the Underwriters' over-
    allotment option is exercised in full, sales by such Selling Stockholders
    would reduce the number of shares of Common Stock held by existing
    stockholders to 8,709,953 or approximately 72.3% of the total number of
    shares of Common Stock outstanding after this Offering and will increase
    the number of shares held by new investors to 3,335,000 or approximately
    27.7% of the total number of shares of Common Stock outstanding after this
    Offering. See "Principal Stockholders" and "Underwriting."
 
  The foregoing analysis assumes (i) no exercise of the Underwriters' over-
allotment option, (ii) issuance of 50,000 shares of Common Stock upon the
exercise of a warrant that expires automatically upon the closing of this
Offering, (iii) no exercise of options after September 30, 1997 and (iv) the
conversion of all outstanding shares of Preferred Stock into Common Stock. As
of September 30, 1997, there were outstanding options to purchase an aggregate
of 1,406,908 shares of Common Stock at a weighted average exercise price of
$1.56 per share. To the extent the above options have been or are exercised,
there will be further dilution to new investors. See "Management--Stock
Plans," "Description of Capital Stock" and Note 9 of Notes to Financial
Statements.

(1) Prior to March 1996, the Company was a subchapter S corporation and,
    therefore, was not subject to entity level taxation. Pro forma net income
    includes pro forma tax expense as if the Company was taxed as a C
    corporation from fiscal 1993 to 1996.
(2) For an explanation of net income (loss) per share and shares used in per

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion should be read in conjunction with the Financial
Statements and Notes thereto included elsewhere in this Prospectus. Certain
statements in this "Management's Discussion and Analysis of Financial
Condition and Results of Operations" are forward looking statements. The
forward looking statements contained herein are based on current expectations
and entail various risks and uncertainties that could cause actual results to
differ materially from those expressed in such forward looking statements. For
a more detailed discussion of these and other business risks, see "Risk
Factors."
 
OVERVIEW
 
  Artisan is a leading developer of high performance, low power and high
density embedded memory and other IP components for the design and manufacture
of complex ICs. The Company licenses its products to semiconductor
manufacturers and fabless semiconductor companies for the design of ICs used
in complex, high volume applications, such as portable computing devices,
cellular phones, consumer multimedia products, automotive electronics,
personal computers and workstations.
 
  Revenue consists of license fees for the Company's IP component products.
Typically, a customer licenses one or more products that are accompanied by
layout databases, views to support a customer's IC design tool environment and
design methodology documentation. The license of the Company's products
typically involves a sales cycle of six to 12 months and often coincides with
a customer's migration to a new manufacturing process. The Company's contracts
generally require a customer to pay a license fee to Artisan ranging from
approximately $400,000 to $800,000 for each product delivered under a
contract. A contract typically calls for an upfront payment of approximately
one third of the full contract value with the remainder due upon delivery,
generally three to six months later. See "Risk Factors--Lengthy Sales Cycle
and Design Process."
 
  To date, the substantial majority of the Company's revenue has been
recognized on a percentage of completion method. Provisions for estimated
losses on the uncompleted contracts are recognized in the period in which the
likelihood of such losses is determined. As the completion period for a
project ranges from three to six months, revenue in any quarter is dependent
on the Company's progress toward completion of the project. There can be no
assurance that the Company's estimates will be accurate, and, in the event
they are not, the Company's business, operating results and financial
condition in subsequent periods could be materially adversely affected.
 
  Currently, license fees represent substantially all of revenue. Beginning in
late fiscal 1996, however, the Company began implementation of a royalty based
business model that is intended to generate revenue from both license fees and
future royalties. Royalties will be based on per unit sales of ICs and will
generally be based on the silicon area of an IC occupied by the Company's IP
components. To date, the Company has received no royalty revenue, and it does
not anticipate receiving any until fiscal 1999. There can be no assurance that
the Company will be successful in expanding the number of royalty bearing
contracts with customers. The Company generally licenses its products on a
nonexclusive, worldwide basis to major semiconductor manufacturers and grants
these manufacturers the right to distribute the Company's IP components freely
to their internal design teams and to fabless semiconductor companies that
manufacture at the same facility. Given that Artisan provides its products
early in the customer's IC design process, there will be a significant delay
between the delivery of a product and the generation of royalty revenue. There
can be no assurance that the Company will receive any royalty revenue or that,
if it does, the amount will be significant. See "Risk Factors--Dependence on
New Business Model."

  The Company has been dependent on a relatively small number of customers for
a substantial portion of its annual revenue, although the customers comprising
this group have changed from time to time. In fiscal 1995, SGS-THOMSON, NEC,
the DOD, Samsung and LSI Logic accounted for 20%, 17%, 17%, 11% and 10% of
revenue, respectively. In fiscal 1996, ATI, SGS-THOMSON, OKI and the DOD
accounted for 37%, 20%, 15% and 10% of revenue, respectively. In fiscal 1997,
SGS-THOMSON, Fujitsu, OKI and NEC accounted for 27%, 24%, 16% and 13% of
revenue, respectively. The Company anticipates that its revenue will continue
to depend on a limited number of major customers for the foreseeable future,
although the companies considered to be major customers and the percentage of
revenue represented by each major customer may vary from period to period
depending on the addition of new contracts and the number of designs utilizing
the Company's products. See "Risk Factors--Customer Concentration; Limited
Customer Base" and "Business--Customers."
 
  A substantial portion of the Company's revenue is derived from customers
outside the United States. In fiscal 1995, 1996 and 1997, revenue from
customers outside the United States, primarily in Asia and Europe, represented
approximately 55%, 47% and 67%, respectively of the Company's revenue. The
Company anticipates that international revenue will remain a substantial
portion of its revenue in the future. To date, all of the revenue from
international customers has been denominated in U.S. dollars. See "Risk
Factors--Risks Associated with International Customers" and Note 11 of Notes
to Financial Statements.
 
  The Company derives substantially all of its revenue from sales of its
memory and standard cell products that, together, accounted for 83%, 79% and
94% of revenue in fiscal 1995, 1996 and 1997, respectively. The Company
expects that memory products, in combination with standard cell products, will
continue to account for a significant portion of the Company's revenue, for
the foreseeable future. There can be no assurance that the Company will
continue to derive revenue from memory or standard cell products and a decline
in revenue from such products would have a material adverse effect on the
Company's business, operating results and financial condition. The Company's
future financial performance will depend in significant part on the successful
development, introduction and customer acceptance of new products.
 
  Since the Company's inception in April 1991, each of the Company's cost and
expense categories has progressively increased as the Company has added
personnel and increased its activities in these areas. The Company intends to
continue making significant expenditures associated with engineering costs and
sales and marketing, and expects that these costs and expenses will continue
to be a significant percentage of revenue in future periods. Whether such
expenses increase or decrease as a percentage of revenue will be substantially
dependent upon the rate of change of the Company's revenue. See Note 2 of
Notes to Financial Statements.
 
  The Company in the past has experienced delays in the progress of certain
projects, and there can be no assurance that such delays will not occur in the
future. Any delay or failure to achieve such progress could result in damage
to customer relationships and the Company's reputation, under-utilization of
engineering resources or a delay in the market acceptance of the Company's
products, any of which could have a material adverse effect on the Company's
business, operating results and financial condition. In addition, the
Company's contracts with customers may generally be canceled without cause,
and if a customer cancels or delays performance under any such contracts, the
Company's business, operating results and financial condition could be
materially adversely affected. The Company's costs and expenses will be based
in part on the Company's expectations of future revenue from license fees.
Accordingly, if the Company does not realize its expected revenue, its
business, operating results and financial condition could be materially
adversely affected. See "Risk Factors--Fluctuations in Operating Results."

 Revenue
 
  Revenue increased by 52.6% from $2.7 million in fiscal 1995 to $4.1 million
in fiscal 1996 and by 114.9% to $8.9 million in fiscal 1997. The growth in
revenue in 1996 was primarily attributable to increased licensing of the
Company's standard cell products and, to a lesser extent, I/O products,
partially offset by a reduction in license revenue from memory products. The
increase in revenue in fiscal 1997 resulted primarily from increases in the
number of licenses of, and prices for, the Company's memory products and, to a
lesser extent, from increases in the number of licenses of, and prices for,
standard cell products. The increase in the number of licenses for standard
cell products in fiscal 1996 and memory products in fiscal 1997 corresponded
to the introduction of new products in each category.
 
 Cost and Expenses
 
  Engineering costs are allocated between cost of revenue and product
development expenses. Engineering efforts devoted to developing products for
specific customer projects are recognized as cost of revenue. The balance of
engineering costs, incurred for general development of Artisan's technology,
is charged to product development. Engineering costs are generally charged as
incurred and do not necessarily correspond to the recognition of revenue under
related contracts. Engineering costs increased by 16.4% from $2.0 million in
fiscal 1995 to $2.4 million in fiscal 1996 and by 102.1% to $4.8 million in
fiscal 1997. Engineering costs as a percentage of revenue were 74.6%, 56.9%
and 53.5% for fiscal 1995, 1996 and 1997, respectively. The increase in the
level of engineering costs was due primarily to an increase in engineering
personnel, and the decrease as a percentage of revenue stemmed from revenue
growth in excess of the growth in engineering expenses.
 
    Cost of Revenue. Cost of revenue increased by 30.1% from $984,000 in
  fiscal 1995 to $1.3 million in fiscal 1996 and by 123.0% to $2.9 million in
  fiscal 1997. As a percent of
 
                                      21
<PAGE>
 
  revenue, cost of revenue was 36.2%, 30.9% and 32.0% for fiscal 1995, 1996
  and 1997, respectively. The increases in absolute dollars in fiscal 1996
  and 1997 were due to increases in headcount and costs associated with
  customer support for a growing customer base.
 
    Product Development Expenses. Product development expenses increased by
  3.4% from $1.0 million in fiscal 1995 to $1.1 million 1996 and by 77.2% to
  $1.9 million in fiscal 1997. Product development expenses as a percentage
  of revenue were 38.4%, 26.0% and 21.5% for fiscal 1995, 1996 and 1997,
  respectively. The increase in absolute dollars from fiscal 1996 to fiscal
  1997 was attributable to increased headcount and infrastructure
  investments, including workstations and EDA tool purchases necessary for
  the development of a new generation of high speed memory products and
  enhancements to the Company's standard cell products. The decrease in
  product development expenses as a percentage of revenue during these
  periods was primarily the result of the growth in revenue. The Company
  expects that product development expenses will continue to increase in
  absolute dollars. Whether such expenses increase or decrease as a
  percentage of revenue will be substantially dependent upon the rate of
  change of the Company's revenue.
 
    Sales and Marketing Expenses. Sales and marketing expenses include
  salaries, commissions, travel expenses and costs associated with trade
  shows, advertising and other marketing efforts. Costs of pre-sale customer
  support are also charged to sales and marketing. Sales and marketing
  expenses increased by 121.7% from $272,000 in fiscal 1995 to $603,000 in
  fiscal 1996 and by 234.8% to $2.0 million in fiscal 1997. Sales and
  marketing expenses as a percentage of revenue were 10.0%, 14.6% and 22.7%
  for fiscal 1995, 1996 and 1997, respectively. The growth in sales and
  marketing expenses was primarily attributable to increased trade show
  participation and headcount as well as, in fiscal 1997, advertising and
  costs associated with the Company's name change. The Company expects sales
  and marketing expenses to increase in absolute dollars in the future as the
  Company increases headcount to expand account coverage and provide
  increased customer support. The rate of increase of, and the percentage of
  revenue represented by, sales and marketing expenses in the future will
  vary from period to period based on the trade show, advertising,
  promotional and other sales and marketing activities undertaken, the change
  in sales and marketing headcount in any given period and the rate of change
  in the Company's revenue.
 
    General and Administrative Expenses. General and administrative expenses
  increased by 47.2% from $415,000 in fiscal 1995 to $611,000 in fiscal 1996
  and by 119.3% to $1.3 million in fiscal 1997. General and administrative
  expenses as a percentage of revenue were 15.3%, 14.7% and 15.0% for fiscal
  1995, 1996 and 1997, respectively. Increases in general and administrative
  expenses during these periods are the result of increases in headcount and
  in legal, accounting and other professional expenses. The Company expects
  general and administrative expenses to grow in absolute dollars in future
  periods as the Company expands its operations and as a result of expenses
  associated with being a public company. The rate of increase of and the
  percentage of revenue represented by general and administrative expenses in
  the future will depend on the rate of change of the Company's revenue.
 
 Other Income
 
  Other income increased from zero in 1995 to $96,000 in fiscal 1996 and by
209.4% to $297,000 in fiscal 1997. Other income as a percentage of revenue was
0%, 2.3% and 3.3% in fiscal 1995, 1996 and 1997, respectively. The growth in
other income in fiscal 1996 and 1997 reflects interest income earned on the
proceeds of the Company's Series A and Series B Preferred Stock financings in
March 1996 and December 1996, respectively.
 
                                      22

 Income Taxes
 
  The provision for income taxes was $36,000, $137,000 and $356,000 in fiscal
1995, 1996 and 1997, respectively. The Company's effective tax rate was 32.9%
in fiscal 1997. Prior to March 1996, the Company was a subchapter S
corporation and, therefore, was not subject to entity level taxation. Fiscal
1995 taxes consist of foreign income and franchise taxes. In March 1996, the
Company converted to a C corporation and thereafter has been a cash basis
taxpayer for federal and state income tax purposes. Pro forma net income
includes pro forma tax expense as if the Company was taxed as a C corporation
in fiscal 1995 and 1996.

  The Company's revenue increased in each quarter of fiscal 1997. Revenue
growth during these periods was primarily due to increased licensing of the
Company's memory and standard cell products. Quarter to quarter results
fluctuated significantly as a result of the small number of projects in
various stages of completion at any point in time.
 
                                      24

  Engineering costs, which are allocated between cost of revenue and product
development, generally increased in proportion to the growth in revenue. The
relative contribution, however, of cost of revenue and product development
expenses to total engineering costs has tended to fluctuate from quarter to
quarter in fiscal 1997. The Company expects this fluctuation to continue due
to a number of factors, including the number and mix of customer projects and
the extent and duration of new product and technology development initiatives
underway in any given quarter.
 
  Sales and marketing expenses fluctuated in the quarters presented due to
variations in sales and marketing efforts for advertising and promotional
activities, trade shows, increased headcount and costs associated with the
Company's name change. The Company expects sales and marketing expenses to
increase in the future as the Company continues to build the infrastructure
necessary to sell to and support a growing number of customers. The rate of
increase of, and the percentage of revenue represented by, sales and marketing
expenses in the future will vary from period to period based on trade show,
advertising, promotion and other sales and marketing activities undertaken,
the change in sales and marketing headcount in any given period and the rate
of change in the Company's revenue.
 
  General and administrative expenses increased in absolute dollars in each
quarter of fiscal 1997 as a result of increased administrative efforts
necessary to manage the Company's growth. However, general and administrative
expenses decreased as a percentage of revenue due to more rapidly increasing
revenue in the third and fourth quarters of fiscal 1997. The Company expects
general and administrative expenses to grow in absolute dollars in future
periods as the Company expands its operations and as a result of costs
associated with being a public company. The rate of increase of, and the
percentage of revenue represented by, general and administrative expenses in
the future will depend on the rate of change of the Company's revenue.
 
  Other income increased significantly in the second quarter of fiscal 1997
because of interest earned on the proceeds of sales of the Company's Series B
Preferred Stock. Other income declined in the fourth quarter of 1997 from the
previous quarter as the Company used a portion of its cash to fund tenant
improvements for its new facilities.
 
  The Company's operating results have fluctuated in the past as a result of a
number of factors including the relatively large size and small number of
customer orders during a given period; the timing of customer orders; delays
in the design process due to changes by a customer to its order after it is
placed; the Company's ability to achieve progress on percentage of completion
contracts; the length of the Company's sales cycle; the Company's ability to
develop, introduce and market new products and product enhancements; the
timing of new product announcements and introductions by the Company and its
competitors; market acceptance of the Company's products; the demand for
semiconductors and end user products that incorporate semiconductors; and
general economic conditions. The Company's future operating results may
fluctuate from quarter to quarter and on an annual basis as a result of these
and other factors, in particular the relatively large size and small number of
customer orders during a given period and the rate of royalties recognized in
a given period. Accordingly, it is likely that in some future quarter the
Company's operating results will be below the expectations of public market
analysts and investors. In such event, the price of the Company's Common Stock
would likely decline, perhaps substantially. See "Risk Factors--Fluctuations
in Operating Results" and "Overview."
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company has funded its operations primarily from approximately $20.3
million in license revenue received from inception to September 30, 1997 and,
to a lesser extent, the sale of approximately $7.7 million of Preferred Stock
and a warrant.
 
                                      25
<PAGE>
 
  The Company's operating activities were essentially cash neutral in fiscal
1995, provided net cash of $566,000 in fiscal 1996, and provided net cash of
$757,000 in fiscal 1997. Net cash provided by operating activities in fiscal
1996 and fiscal 1997 was due primarily to net income plus depreciation and
amortization.
 
  Net cash used in investing activities was $86,000, $3.0 million and $4.6
million in fiscal 1995, 1996 and 1997, respectively. Investing activities have
consisted primarily of net purchases of marketable securities and purchases of
property and equipment. See Notes 5 and 6 of Notes to Financial Statements.
 
  Net cash provided by financing activities was $57,000, $3.2 million and $4.2
million in fiscal 1995, fiscal 1996 and fiscal 1997, respectively. Financing
activities have consisted primarily of sales of convertible Preferred Stock
partially offset, in 1996, by payments on the Company's line of credit. See
Note 9 of Notes to Financial Statements.
 
  At September 30, 1997, the Company had cash, cash equivalents and current
and noncurrent marketable securities of $4.6 million. As of September 30,
1997, the Company had retained earnings of $1.0 million and working capital of
$4.4 million, including a short term component comprised of deferred revenue
of $1.4 million. The Company anticipates spending at least $850,000 for
equipment lease and office lease payments and approximately $3.4 million for
capital expenditures over the next 12 months. See Note 8 of Notes to Financial
Statements.
 
  The Company entered into a $300,000 line of credit with Union Bank of
California, N.A. ("Union Bank") in March 1996, and renewed such agreement.
Pursuant to its agreement with Union Bank, the Company is required to satisfy
certain financial covenants, including those relating to working capital,
tangible net worth and after tax profit levels. As of September 30, 1997, the
Company had no borrowings under this credit facility.
 
  The Company intends to continue to invest heavily in the development of new
products and enhancements to its existing products. The Company's future
liquidity and capital requirements will depend upon numerous factors,
including the costs and timing of expansion of product development efforts and
the success of these development efforts, the costs and timing of expansion of
sales and marketing activities, the extent to which the Company's existing and
new products gain market acceptance, competing technological and market
developments, the costs involved in maintaining and enforcing patent claims
and other intellectual property rights, the level and timing of license
revenue, available borrowings under line of credit arrangements and other
factors. The Company believes that the proceeds from this Offering, together
with the Company's current cash balances and any cash generated from
operations and from available or future debt financing, will be sufficient to
meet the Company's operating and capital requirements for at least the next 12
months. However, there can be no assurance that the Company will not require
additional financing within this time frame. The Company's forecast period of
time through which its financial resources will be adequate to support its
operations is a forward looking statement that involves risks and
uncertainties, and actual results could vary. The factors described in this
paragraph will affect the Company's future capital requirements and the
adequacy of its available funds. The Company may be required to raise
additional funds through public or private financing, strategic relationships
or other arrangements. There can be no assurance that such funding, if needed,
will be available on terms attractive to the Company, or at all. Furthermore,
any additional equity financing may be dilutive to stockholders, and debt
financing, if available, may involve restrictive covenants. Strategic
arrangements, if necessary to raise additional funds, may require the Company
to relinquish its rights to certain of its technologies or products. The
failure of the Company to raise capital when needed could have a material
adverse effect on the Company's business, operating results and financial
condition. See "Risk Factors--Future Capital Needs; Uncertainty of Additional
Funding" and "Use of Proceeds."

                                   BUSINESS
 
  Artisan is a leading developer of high performance, low power and high
density embedded memory and other IP components for the design and manufacture
of complex ICs. The Company offers highly differentiated memory, standard cell
and I/O components that meet the acute needs of complex System-on-a-Chip ICs
for performance, power and density. Together, memory, standard cell and I/O
components constitute approximately 80% of the silicon area on a typical
System-on-a-Chip IC. The Company's products are optimized for each customer's
manufacturing process and are delivered ready for use with industry standard
and proprietary IC design tools. The Company licenses its products to
semiconductor manufacturers and fabless semiconductor companies for the design
of ICs used in complex, high volume applications, such as portable computing
devices, cellular phones, consumer multimedia products, automotive
electronics, personal computers and workstations.
 
INDUSTRY BACKGROUND
 
  The development of the merchant IP component market has resulted from the
continuing trend toward horizontal specialization in the semiconductor
industry, a trend that has been driven by a growth in manufacturing capacity
and an increasing focus on core competencies. In the 1970s, semiconductor
companies were vertically integrated and responsible for all aspects of IC
production, including IC design, EDA tool design, IP component design and IC
manufacturing. In the 1980s, application specific integrated circuit ("ASIC")
companies developed a new approach that allowed their customers to perform the
logic design of an IC while they performed the detailed physical
implementation of the design and manufactured the IC. In addition, standalone
EDA tool vendors achieved success by providing software design tools to
complement those developed by internal divisions of semiconductor companies.
The early 1990s saw the emergence of a number of fabless semiconductor
companies that chose to focus on specific design expertise, take advantage of
the availability of excess semiconductor manufacturing capacity and avoid the
capital expenditures necessary to build fabrication facilities. Throughout
this period, semiconductor manufacturers continued to focus on their core
competencies: semiconductor design and manufacturing processes. Today, with
the emergence of System-on-a-Chip ICs, semiconductor manufacturers are
beginning to outsource the design of particular IP components critical to the
successful development of System-on-a-Chip ICs. This trend favors the
emergence of a substantial merchant IP component market that is estimated by
industry sources to grow from approximately $600 million in 1997 to
approximately $2.0 billion in the year 2001.
 
  Over the past three decades, advances in semiconductor manufacturing
processes have enabled the transistor density on ICs to double every 18
months. Today, it is possible to place approximately 40 million transistors on
a single IC, a number that is widely expected to increase to nearly 100
million transistors by the end of the decade. State of the art fabrication
facilities of the 1980s produced ICs using process geometries of 1.0^ (one
millionth of a meter). Current state of the art fabrication facilities use
0.25^ process geometries, and many semiconductor manufacturers have begun the
transition to facilities using 0.18^ processes. These advances enable the
manufacture of highly complex System-on-a-Chip ICs, resulting in substantial
performance, power, cost and reliability improvements over conventional multi-
chip systems on printed circuit boards ("PCB Systems"). System-on-a-Chip ICs
combine all of the functionality of PCB systems onto a single IC and are
optimal for use in complex, high volume applications such as portable
computing devices, cellular phones, consumer multimedia products, automotive
electronics, personal computers and workstations.

    [Schematic depiction of a printed circuit board and a System-on-a-Chip]
 
  As shown above, in both a PCB System and a System-on-a-Chip, the primary
building blocks include memory, standard cell (logic), I/O, microprocessor,
digital signal processor ("DSP"), mixed-signal and analog components. However,
integration of these components into System-on-a-Chip ICs at deep submicron
process geometries is far more complex than the design of a traditional PCB
System. With continuing advances in manufacturing processes, an increasing
number of individual transistors must be designed and tested and,
consequently, the gap is increasing between what can be manufactured and what
can be designed within the time to market requirements of the semiconductor
manufacturer. As a result, the full value of today's semiconductor
manufacturing processes is rarely realized, with designers settling for
partial utilization of the process in the interest of meeting cost and
schedule requirements. Given shorter product life cycles and the importance of
reducing time to market, the use of merchant IP components to leverage design
and manufacturing capabilities can be a significant competitive advantage to
semiconductor manufacturers.
 
  Semiconductor manufacturers require solutions that fully utilize their
manufacturing processes in order to maximize performance, speed and density
while reducing time to market. Although the merchant EDA industry has
successfully developed partial solutions to increase design productivity, EDA
tools have not completely overcome the time constraints posed by the need to
create IP components for each IC design in a compressed time to market window.
Merchant suppliers of portable generic IP libraries have also improved design
productivity by offering products designed to work with many manufacturing
processes. However, these generic libraries do not fully utilize the depth and
strengths of a particular manufacturing process. Semiconductor manufacturers
have also tried to expand their design resources, but establishing and
maintaining a large internal design group may divert finite resources from a
semiconductor manufacturer's core competencies. Despite the development and
use of EDA tools and generic libraries, and the expansion of internal design
resources, the rapid pace of manufacturing process improvements has continued
to outstrip design capabilities. As a result, the Company believes many
semiconductor manufacturers will utilize merchant IP components in order to
maximize the performance of their product offerings and improve their time to
market.

THE ARTISAN SOLUTION
 
  Artisan is a leading developer of high performance, low power and high
density embedded memory, standard cell and I/O components for the design and
manufacture of complex ICs. The Company provides IP components that are
optimized for each customer's manufacturing process.
 
  The Company's IP components are designed to offer customers the following
benefits:
 
  Performance, Power and Reliability. Artisan delivers high performance, low
power and reliable IP components through a combination of design expertise and
proprietary technology and design tools. The Company's IP components, which
are customized, verified and tested for a particular manufacturing process,
require little or no integration by customers and have been proven by use in
25 different manufacturing processes. Many of the Company's products are
designed to achieve speeds in excess of 300 MHz.
 
  Significant Time to Market Advantages. The Company enables semiconductor
manufacturers to reduce the time required to bring new ICs to market by (i)
eliminating the customer's need to design IP components, (ii) delivering
products designed for a specific manufacturing process and (iii) delivering
products ready for use with industry standard and proprietary IC design tools.
The Company's products can be reused in multiple customer designs, which
reduces design time and decreases time to market for new ICs.
 
  Long Term Product Development Path. Artisan's IP component technology pro-
vides semiconductor manufacturers with reliable building blocks for future
generations of their complex IC designs. Artisan's ability to adapt and cus-
tomize IP components used in one process and one design for use in additional
designs and processes provides each customer with a clear development path for
future designs and processes. This enables the Company's customers to stan-
dardize on Artisan products, accelerate their product development and focus
internal engineering resources on core competencies, including semiconductor
design and manufacturing processes.
 
  Cost Effective Solutions. As semiconductor dies shrink and the complexity of
IC designs increases, the cost to design System-on-a-Chip ICs increases
significantly. By providing reliable products with significant time to market
benefits, Artisan enables customers to reduce design costs, minimize
integration costs and increase manufacturing yield. Moreover, by using the
Company's products, semiconductor manufacturers avoid the cost of recruiting
and training a significant group of engineers dedicated to IP component
design.
 
ARTISAN STRATEGY
 
  The Company's objective is to be the leading supplier of high performance IP
components to the semiconductor industry. The Company's strategy is based upon
the following key elements:
 
  Focus on Key Components For High Volume System-on-a-Chip ICs. The Company
has targeted the rapidly growing System-on-a-Chip industry with high
performance memory, standard cell and I/O components. Together, these
components constitute approximately 80% of the silicon area on a typical
System-on-a-Chip IC. Improvements in the performance of these components,
particularly memory, can have a substantial impact on the overall performance
of the IC.
 
  Target Leading Semiconductor Manufacturers. The Company focuses on licensing
its products to the world's leading semiconductor manufacturers. These
manufacturers represent the largest revenue potential for the Company because
they utilize the most advanced
 
                                      29
<PAGE>
 
manufacturing processes, manufacture the largest number of ICs, have the most
pressing need for high performance IP components and face the greatest time to
market pressures. To date, the Company has licensed its products to many
leading semiconductor manufacturers including Chartered, Fujitsu, GEC Plessey,
NEC, OKI, SGS-THOMSON, Toshiba and VLSI Technology.
 
  Generate Revenue Through Innovative Business Model. In late fiscal 1996, the
Company began implementation of a royalty based business model that is
intended to generate revenue from both license fees and future royalties.
Although the Company currently generates revenue solely from license fees, the
Company expects to recognize royalty revenue beginning in fiscal 1999.
Royalties will be based on per unit sales of ICs and will generally be based
on the silicon area of an IC occupied by the Company's IP components. In order
to maximize royalties, the Company primarily licenses its products on a
nonexclusive, worldwide basis to major semiconductor manufacturers and grants
these manufacturers the right to distribute the Company's IP components freely
to their internal design teams and to fabless semiconductor companies that
manufacture at the same facility. As a result, the Company believes its
license agreements will facilitate the broad and rapid penetration of the
Company's products into multiple designs, and thereby increase potential
royalty revenue.
 
  Proliferate Artisan's IP Components Throughout Customer Designs. The Company
intends to establish itself as the DE FACTO supplier of key IP components
across multiple IC designs and new product generations for each customer. By
making its components easy to integrate into the customer's design
methodologies and supporting both industry standard and proprietary IC design
tools, Artisan facilitates the ready inclusion of its IP components in a large
number of designs. For example, SGS-THOMSON has licensed Artisan's embedded
memory products that, in 1996, were used in more than 200 of SGS-THOMSON's IC
designs.
 
  Leverage Product Development Process. Artisan has developed a large
portfolio of IP building blocks and design tools that allows the Company to
rapidly develop new products. As its customer relationships mature, the
Company believes that the development time for additional products for a
customer will decrease due to the Company's growing base of knowledge and
understanding of the customer's manufacturing processes. The Company intends
to continue to improve the efficiency of its product development process in
order to decrease product delivery time.
 
  Maintain Technological Leadership. The Company believes that it provides the
fastest memory products and the most dense standard cell product currently
available in the merchant IP component market. The Company intends to maintain
its technological leadership position by continuing to develop a significant
portfolio of IP building blocks upon which it can base new generations of
products and make enhancements to existing products. The Company also intends
to maintain its expertise in state of the art manufacturing processes by
working with customers during their new process development efforts.
 
PRODUCTS AND APPLICATIONS
 
 Products
 
  Artisan's current family of IP components includes high performance and low
power memory, standard cell and I/O components. Initial license fees typically
range from $400,000 to $800,000 per component, depending on the amount of
customization and the number of design views and models required.
 
  Artisan's products are developed and delivered using a proprietary
methodology that includes a set of design tools, techniques and specific
design expertise that the Company calls "Process-Perfect." This methodology
ensures that the IP components produced by Artisan are
 
                                      30
<PAGE>
 
designed to achieve the best combination of performance, power, density and
yield for a given manufacturing process. In addition, the Company has created
a flexible portfolio of IP  building blocks. This portfolio, combined with the
Process-Perfect methodology, allows the Company to satisfy its customers'
schedule and quality requirements in a cost effective manner. Artisan's IP
components are easily integrated into a variety of customer design
methodologies and support industry standard IC design tools, including those
from EDA tool vendors such as Cadence, Synopsys and Avant!, as well as
customers' proprietary IC design tools. To support these various IC design
tool environments, each of the Company's products includes a comprehensive set
of verified tool models.
 
  MEMORY PRODUCTS. Artisan's embedded memory products include random access
memories ("RAMs"), read only memories ("ROMs") and register files. The
Company's HS300 and LP133 products include single- and dual-port RAM and ROM
products and dual- and triple-port register files. The Company's embedded
memory products are configurable and vary in size to meet the customer's
specification. For example, the Company's RAM products will support sizes from
2 to 128 bits wide and from 16 to 8,192 words. All of the Company's memory
products include features such as a power down mode, low voltage data
retention and fully static operation. In addition, the Company's memory
products include built-in test interfaces that support popular test
methodologies.
 
    HS300. The HS300 products are designed to achieve speeds in excess of 300
  MHz for .25^ manufacturing processes. The Company achieves the high
  performance of its HS300 products through a combination of proprietary
  design innovations that include latch based sense amplifiers, high speed
  row select technology, precise core cell balancing and rapid recovery
  bitlines.
 
    LP133. The LP133 products are designed to operate at low power levels and
  to achieve speeds in excess of 133 MHz for .25^ manufacturing processes.
  The LP133 products achieve low power through a combination of proprietary
  design innovations that include latch based sense amplifiers, a power
  efficient banked memory architecture, precise core cell balancing and
  unique address decoder and driver circuitry.
 
  STANDARD CELL PRODUCT. Artisan's standard cell product includes over 400
cells optimized for each customer's manufacturing process and IC design tool
environment resulting in greater density as compared to competitive standard
cell products. The Company's standard cell product utilizes each customer's
proprietary manufacturing process rules including stacked contact-via,
silicided diffusion and local interconnect layers. All functions are available
in at least four drive strengths, and the Company's inverters, buffers and 3-
state drivers are each available in nine drive strengths.
 
  I/O PRODUCTS. The Company's I/O products comply with industry standard
specifications and conform to the ESD and electrical guidelines of each
customer's manufacturing process, resulting in improved manufacturing yield
and reliability. Examples of the Company's I/O products include oscillator
circuits, slew-rate controlled I/Os and I/Os with selectable output drive
strengths. The Company's I/O products are designed to support ICs
incorporating industry standard PCI, GTL and PECL interfaces or custom
interfaces.
 
 Applications
 
  SGS-THOMSON has licensed memory products from Artisan since 1992 because
such products have met SGS-THOMSON's demanding requirements for performance,
density, power and yield. SGS-THOMSON believes that Artisan's memory products
significantly increase the value of its IC offerings to customers. In 1996,
SGS-THOMSON used Artisan's embedded
 
                                      31
<PAGE>
 
memory products in more than 200 of its IC designs. SGS-THOMSON has licensed
Artisan's embedded memory products for six different manufacturing processes,
including its 0.5 micron, 0.35 micron and 0.25 micron process geometries.
 
  In 1994, NEC began developing a complex IC for the Nintendo 64 video
entertainment system. NEC selected Artisan's memory products because they
would enable NEC to show a clear competitive advantage in the workstation,
graphics/multimedia and networking market segments. Artisan was able to deliver
memory products that were customized for NEC's manufacturing process on an
aggressive delivery schedule which allowed NEC to focus on other design
attributes of the IC for the Nintendo 64. NEC has since licensed Artisan's
memory products for its 0.5 micron, 0.35 micron and 0.25 micron manufacturing
processes.
 
  In June 1997, Fujitsu signed an agreement with Artisan to purchase a variety
of Artisan's products, including embedded memory, standard cell and I/O cell
products, for initial implementation into Fujitsu's advanced 3D graphics ICs
that will support the "Talisman" graphics standard. Talisman is a development
effort to turn the 3D graphics architecture developed by Microsoft into a
single IC for mainstream multimedia applications, and Fujitsu is a founding
member of the Talisman Consortium. By utilizing the Company's products, Fujitsu
can accelerate its product development and meet the needs of the Talisman
architecture. The Talisman ICs will be built using Fujitsu's 0.25 micron
manufacturing process and will use a variety of Artisan's products, including
the HS300 embedded memory, standard cell and I/O products to support Fujitsu's
high performance requirements.
 
PRODUCT DEVELOPMENT
 
  The Company has targeted the rapidly growing System-on-a-Chip market with
high performance and low power memory, standard cell and I/O products. The
ability of the Company to compete in the future will be substantially
dependent on its ability to continually create competitive technologies to
meet changing market needs. To this end, the Company's engineers are involved
in the development of more advanced versions of the Company's products as well
as the development of new products. The Company has assembled a team of highly
skilled engineers whose activities are focused on the development of IP
components for current and anticipated manufacturing processes. Because of the
complexity of these activities, the design and development process at Artisan
is a multidisciplinary effort requiring expertise in electronic circuit
design, process technology, physical layout, design software, model
generation, data analysis and processing and general IC design.
 
  As of September 30, 1997, Artisan had 41 employees in the engineering
department. In fiscal 1995, 1996 and 1997, total engineering costs were
approximately $2.0 million, $2.4 million and $4.8 million, respectively.
Engineering costs are allocated between cost of revenue and product
development expense. Engineering efforts devoted to developing products for
specific customer projects are recognized as cost of revenue while the balance
of engineering costs, incurred for general development of Artisan's
technology, is charged to product development. The Company expects that it
will continue to invest substantial funds for engineering activities. There
can be no assurance that the Company can develop and introduce new technology
in a timely fashion or that such new technology will be accepted by the
market. See "Risk Factors--New Product Development and Technological Change."
 
  The Company's customers compete in the semiconductor industry, which is
subject to rapid technological change, frequent introductions of new products,
short product life cycles, changes in customer demands and requirements and
evolving industry standards. Accordingly, the Company's future success will
depend on its ability to continue to enhance its existing products and to
develop and introduce new products that satisfy increasingly sophisticated
customer
 
                                      32
<PAGE>
 
requirements and that keep pace with new product introductions, emerging
manufacturing processes and other technological developments in the
semiconductor industry. The development of new manufacturing processes,
introduction of products embodying new technologies and the emergence of new
industry standards can render existing products obsolete and unmarketable. Any
failure by the Company to anticipate or respond adequately to changes in
manufacturing processes or customer requirements, or any significant delays in
product development or introduction, would have a material adverse effect on
the Company's business, operating results and financial condition. There can
be no assurance that the Company will not experience difficulties which could
delay or prevent the successful development, introduction and sale of new or
enhanced products or that such new or enhanced products will achieve market
acceptance. Any delay in release dates of new or enhanced products could
materially adversely affect the Company's business, operating results and
financial condition. The Company could also be exposed to litigation or claims
from its customers in the event that it does not satisfy its delivery
commitments. There can be no assurance that any such claim would not have a
material adverse effect on the Company's business, operating results and
financial condition.
 
CUSTOMERS
 
  The Company is focused on licensing its products to manufacturers in the
semiconductor market. Many of the world's leading semiconductor manufacturers
are among the Company's customers, and since inception the Company has sold
its products to 19 semiconductor manufacturers and fabless semiconductor
companies. The following chart identifies all customers that initiated new
licenses of IP components from the Company since the beginning of fiscal 1995.

  The Company has been dependent on a relatively small number of customers for
a substantial portion of its annual revenue, although the customers comprising
this group have changed from time to time. In fiscal 1995, SGS-THOMSON, NEC,
the DOD, Samsung and LSI Logic accounted for 20%, 17%, 17%, 11% and 10% of
revenue, respectively. In fiscal 1996, ATI, SGS-THOMSON, OKI and the DOD
accounted for 37%, 20%, 15% and 10% of revenue, respectively. In fiscal 1997,
SGS-THOMSON, Fujitsu, OKI and NEC accounted for 27%, 24%, 16% and 13% of
revenue, respectively. The Company anticipates that its revenue will continue
to depend on a limited number of major customers for the foreseeable future,
although the companies considered to be major customers and the percentage of
revenue represented by each major customer may vary from period to period
depending on the addition of new contracts and the number of designs utilizing
the Company's products. None of the Company's customers has a written
agreement with the Company that obligates it to license additional products,
and there can be no assurance that any customer will license IP components
from the Company in the future. The loss of one or more of the Company's major
customers, or reduced orders by one or more of such customers, could
materially adversely affect the Company's business, operating results and
financial condition. See "Risk Factors--Customer Concentration" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
  There can be no assurance that the Company will be successful in continuing
to license its products to current customers or entering into licenses with
additional semiconductor manufacturers. The Company faces numerous risks in
successfully obtaining orders from customers on terms consistent with the
Company's business model including, among others, the lengthy and expensive
process of building a relationship with a potential customer before reaching
an agreement with such party to license the Company's products; persuading
large semiconductor manufacturers to work with, disclose proprietary
information to and rely upon, a smaller company, such as the Company; and
persuading potential customers to bear certain development costs associated
with development of customized components. In addition, there are a relatively
limited number of semiconductor manufacturers to which the Company can license
its technology in a manner consistent with its business model. The Company
also faces significant competition from internal design groups of
semiconductor manufacturers. See "--Competition" and "Risk Factors--
Competition."
 
SALES, MARKETING AND DISTRIBUTION
 
  The Company primarily licenses its products on a nonexclusive, worldwide
basis to major semiconductor manufacturers and grants these manufacturers the
right to distribute its IP components freely to their internal design teams
and to fabless semiconductor companies that manufacture at the same facility.
The Company's sales, marketing and distribution approach gives it an advantage
over its competitors since the Company is able to leverage its customers'
sales and marketing organizations and avoid the costs associated with hiring,
training and compensating the large sales force necessary to sell directly to
each end user customer. As of September 30, 1997, the Company's sales and
marketing organization was comprised of four sales and four marketing
employees. In parts of Asia, the Company relies in part on a consulting
company to assist its sales efforts.
 
  A substantial portion of the Company's revenue is derived from customers
outside the United States. In fiscal 1995, 1996 and 1997, revenue derived from
customers outside the United States, primarily in Asia and Europe, represented
approximately 55%, 47% and 67%, respectively, of the Company's revenue. The
Company anticipates that international revenue will remain a substantial
portion of its revenue in the future. To date, all of the revenue from
international customers has been denominated in U.S. dollars. In the event
that the Company's
 
                                      34
<PAGE>
 
competitors denominate their sales in currencies that become relatively
inexpensive in comparison to the U.S. dollar, the Company may experience fewer
orders from international customers whose business is based primarily on the
less expensive currencies. The Company intends to continue to expand its sales
and marketing activities in Asia and Europe. The Company's expansion of its
international business involves a number of risks including the impact of
possible recessionary environments in economies outside the United States;
political and economic instability; exchange rate fluctuations; longer
receivables collection periods and greater difficulty in accounts receivable
collection from customers; unexpected changes in regulatory requirements;
reduced or limited protection for intellectual property rights; export license
requirements; tariffs and other trade barriers; and potentially adverse tax
consequences. There can be no assurance that the Company will be able to
sustain or increase revenue derived from international customers or that the
foregoing factors will not have a material adverse effect on the Company's
business, operating results and financial condition. See "Risk Factors--Risks
Associated with International Sales."
 
COMPETITION
 
  The Company's strategy of targeting semiconductor manufacturers that
participate in, or may enter, the System-on-a-Chip market requires the Company
to compete in intensely competitive markets. Within the merchant segment of
the IP market, the Company competes primarily against Aspec, Avant!, Cascade
Design, Mentor Graphics and Synopsys. In addition, the Company may face
competition from consulting firms and companies that typically have operated
in the generic library segment of the IP market and that now seek to offer
customized IP components as an enhancement to their generic solutions. The
Company also faces significant competition from internal design groups of the
semiconductor manufacturers that are expanding their portfolio of IP
components to participate in the System-on-a-Chip market. These internal
design groups compete with the Company for access to the parent's IP component
requisitions and may eventually compete with the Company to supply IP
components to third parties on a merchant basis. There can be no assurance
that internal design groups will not expand their product offerings to compete
directly with those of the Company or will not actively seek to participate as
merchant vendors in the IP component market by selling to third party
semiconductor manufacturers or, if they do, that the Company will be able to
compete against them successfully. In addition to competition from companies
in the merchant IP component market, the Company faces competition from
vendors that supply EDA software tools, including certain of those mentioned
above, and there can be no assurance that the Company will be able to compete
successfully against them.
 
  The Company expects competition to increase in the future from existing
competitors and from new market entrants with products that may be less costly
than the Company's IP components or that may provide better performance or
additional features not currently provided by the Company. The Company
believes that the principal competitive factors for IP components are speed,
power usage, density, reliability and price. The Company believes that, on
balance, it competes favorably with respect to the above factors.
 
  Many of the Company's current and potential competitors have substantially
greater financial, technical, manufacturing, marketing, distribution and other
resources, greater name recognition and market presence, longer operating
histories, lower cost structures and larger customer bases than the Company.
As a result, they may be able to adapt more quickly to new or emerging
technologies and changes in customer requirements. In addition, certain of the
Company's principal competitors offer a single vendor solution, since, in the
case of EDA companies, they maintain their own EDA design tools and IP
component libraries, or, in the case of internal design groups, they provide
IP components developed to utilize the qualities of a
 
                                      35
<PAGE>
 
given manufacturing process, and may therefore benefit from certain capacity,
cost and technical advantages. The Company's ability to compete successfully
in the emerging market for IP components will depend upon certain factors,
many of which are beyond the Company's control including, but not limited to,
success in designing new products; implementing new designs at smaller process
geometries; access to adequate EDA tools (many of which are licensed from the
Company's current or potential competitors); the price, quality and timing of
new product introductions by the Company and its competitors; the emergence of
new IP component interchangeability standards; the widespread licensing of IP
components by semiconductor manufacturers or their design groups to third
party manufacturers; the ability of the Company to protect its intellectual
property; market acceptance of the Company's IP components; success of
competitive products; market acceptance of products using System-on-a-Chip
ICs; and industry and general economic conditions. There can be no assurance
that the Company will be able to compete successfully in the emerging merchant
IP component market. See "Risk Factors--Competition."
 
PATENTS AND INTELLECTUAL PROPERTY PROTECTION
 
  The Company relies primarily on a combination of nondisclosure agreements
and other contractual provisions and patent, trademark, trade secret, and
copyright law to protect its proprietary rights. The Company has an active
program to protect its proprietary technology through the filing of patents.
As of September 30, 1997, the Company had applications for 13 patents on file
with the USPTO. To date, the USPTO has issued a notice of allowance with
respect to one patent relating to reducing power consumption of the Company's
memory products. As of September 30, 1997, the Company had no filings for
foreign patents, but the Company intends to file such foreign patent
applications as appropriate in the future. There can be no assurance that the
Company's pending patent applications will be approved, that any issued
patents will protect the Company's intellectual property or will not be
challenged by third parties, or that the patents of others will not have an
adverse effect on the Company's ability to do business. Furthermore, there can
be no assurance that others will not independently develop similar or
competing technology or design around any patents that may be issued to the
Company.
 
  The Company also relies on trademark and trade secret laws to protect its
intellectual property. The Company protects its trade secrets and other
proprietary information through confidentiality agreements with its employees
and customers and other security measures. Despite these efforts, there can be
no assurance that others will not gain access to the Company's trade secrets,
that such trade secrets will not be independently discovered by competitors or
that the Company can meaningfully protect its intellectual property. In
addition, effective trade secret protection may be unavailable or limited in
certain foreign countries. Although the Company intends to protect its rights
vigorously, there can be no assurance that such measures will be successful.
 
  Failure of the Company to enforce its patents, trademarks or copyrights or
to protect its trade secrets could have a material adverse effect on the
Company's business, operating results and financial condition. There can be no
assurance that such intellectual property rights can be successfully asserted
in the future or will not be invalidated, circumvented or challenged. From
time to time, third parties, including competitors of the Company, may assert
patent, copyright and other intellectual property rights to technologies that
are important to the Company. There can be no assurance that third parties
will not assert infringement claims against the Company in the future, that
assertions by third parties will not result in costly litigation or that the
Company would prevail in any such litigation or be able to license any valid
and infringed patents from third parties on commercially reasonable terms.
Litigation, regardless of the
 
                                      36
<PAGE>
 
outcome, could result in substantial cost and would divert resources of the
Company. Any infringement claim or other litigation against or by the Company
could materially adversely affect the Company's business, operating results
and financial condition.
 
  In addition, there can be no assurance that competitors of the Company, many
of which have substantial resources and have made substantial investments in
competing technologies, do not have, or will not seek to apply for and obtain,
patents that will prevent, limit or interfere with the Company's ability to
make, use or sell its products either in the United States or in international
markets. There can be no assurance that the Company will not in the future
become subject to patent infringement claims and litigation or interference
proceedings declared by the USPTO to determine the priority of inventions. The
defense and prosecution of intellectual property suits, USPTO interference
proceedings and related legal and administrative proceedings are both costly
and time consuming. Any such suit or proceeding involving the Company could
have a material adverse effect on the Company's business, operating results
and financial condition. See "Risk Factors--Risks Associated with Protection
of Intellectual Property."
 
EMPLOYEES
 
  As of September 30, 1997, the Company had 56 fulltime employees. Of this
total, 41 were in engineering, eight were in sales and marketing and seven
were in finance and administration. None of the Company's employees is
represented by a labor union or is subject to a collective bargaining
agreement. The Company has never experienced a work stoppage and believes that
its relations with employees are good.
 
  The Company's success depends in large part on the continued contributions
of its key management, engineering, sales and marketing personnel, many of
whom are highly skilled and would be difficult to replace. None of the
Company's senior management or key technical personnel is bound by an
employment contract. In addition, the Company does not currently maintain key
man life insurance covering its key personnel. The Company believes that its
success depends to a significant extent on the ability of its management to
operate effectively, both individually and as a group. The Company must also
attract and retain highly skilled managerial, engineering, sales and marketing
and finance personnel. Competition for such personnel is intense, and there
can be no assurance that the Company will be successful in attracting and
retaining such personnel. The loss of the services of any of the key
personnel, the inability to attract or retain qualified personnel in the
future or delays in hiring required personnel, particularly engineers, could
have a material adverse effect on the Company's business, operating results
and financial condition. See "Management--Executive Officers and Directors."
 
FACILITIES
 
  The Company's executive, administrative and technical offices currently
occupy 32,660 square feet in Sunnyvale, California, under a lease that expires
in 2004. The Company sublets to a third party the 16,797 square foot space it
formerly occupied in San Jose, California. The lease on the San Jose space
expires in 2001. The Company believes that its existing facilities are
adequate to meet its current needs but that it may need to seek additional
space in the future. The Company believes that suitable additional space will
be available on commercially reasonable terms as needed.

LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS
 
  The Company has adopted provisions in its Articles of Incorporation that
eliminate, to the fullest extent permissible under California law, the
liability of its directors to the Company for monetary damages. Such
limitation of liability does not affect the availability of equitable remedies
such as injunctive relief or rescission. The Company's California Bylaws
provide that the Company shall indemnify its directors and officers to the
fullest extent permitted by California law, including in circumstances in
which indemnification is otherwise discretionary under California law.
 
  In connection with the Company's reincorporation in Delaware, the Company's
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 for liability (i) for any breach
of their duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or that involve intentional misconduct or a
knowing violation of law, (iii) for unlawful payments of dividends or unlawful
stock repurchases or redemptions as provided in Section 174 of the Delaware
General Corporation Law or (iv) for any transaction from which the director
derived an improper personal benefit.
 
  The Company's Delaware Bylaws provide that the Company will indemnify its
directors and executive officers and may indemnify its other officers and
employees and other agents to the fullest extent permitted by law. The Company
believes that indemnification under its Delaware Bylaws covers negligence and
may cover gross negligence on the part of indemnified parties. The Company's
Delaware Bylaws also permit the Company to secure insurance on behalf of any
officer, director, employee or other agent for any liability arising out of
his or her actions in such capacity, regardless of whether the Delaware Bylaws
would permit indemnification.
 
  Prior to the effective date of this Offering, the Company will enter into
agreements to indemnify its directors and officers, in addition to
indemnification provided for in the Company's Bylaws. These agreements, among
other things, will indemnify the Company's
 
                                      40
<PAGE>
 
directors and officers for certain expenses (including attorneys' fees and
other costs), judgments, fines, penalties and settlement amounts incurred by
any such person in any action or proceeding, including any action by or in the
right of the Company, arising out of such person's services as a director or
officer of the Company, any subsidiary of the Company or any other Company or
enterprise to which the person provides services at the request of the
Company. The Company believes that these provisions and agreements are
necessary to attract and retain qualified directors and officers.
 
  At the present time, there is no pending litigation or proceeding involving
a director, officer, employee or other agent of the Company in which
indemnification would be required or permitted. The Company is not aware of
any threatened litigation or proceeding that may result in a claim for such
indemnification.

(1) Amounts represent hypothetical gains that could be achieved for the
    respective options if exercised at the end of the option term. The assumed
    5% and 10% rates of stock price appreciation are mandated by rules of the
    Securities and Exchange Commission and do not represent the Company's
    estimate or projection of the future Common Stock price. Actual gains, if
    any, on stock option exercises are dependent on the future financial
    performance of the Company, overall conditions and the option holder's
    continued employment through the vesting period and option term. This
    table does not take into account any appreciation in the fair market value
    of the Common Stock from the date of grant to the date of this offering,
    other than the columns reflecting assumed rates of appreciation of 5% and
    10%.
(2) The option granted during fiscal 1997 to Mr. Lewis was granted under the
    1993 Plan. Subject to Mr. Lewis' continued employment with the Company,
    the option becomes exercisable as to 25% of the option shares on the first
    anniversary of the date of grant and as to 6.25% per quarter thereafter,
    with full vesting occurring on the fourth anniversary of the date of
    grant. See "--Stock Plans."
(3) Options were granted at an exercise price equal to the fair market value
    of the Company's Common Stock on the date of grant, as determined by the
    Board of Directors. The Company's Common Stock was not traded publicly at
    the time of the foregoing grant to Mr. Lewis.

(1) "Value realized" is calculated on the basis of the fair market value of
    the Common Stock on the date of exercise minus the exercise price, does
    not necessarily indicate that the optionee sold such stock and does not
    take into account that some of such shares are subject to rights of
    repurchase on the part of the Company that lapse at various times over
    four years after the date of grant.
(2) Based upon the fair market value of $5.00 per share as of fiscal year end
    minus the exercise price.
(3) Consists of three options with exercise prices of $0.01, $0.15 and $0.15,
    respectively.
 
STOCK PLANS
 
  1993 Stock Option Plan. The 1993 Plan was adopted by the Board of Directors
and approved by the Company's stockholders in October 1993. A total of
4,291,396 shares of Common Stock has been reserved for issuance under the 1993
Plan. The 1993 Plan provides for grants of incentive stock options to
employees (including officers and employee directors) and nonstatutory stock
options to consultants (including nonemployee directors) of the Company. The
purpose of the 1993 Plan is to attract and retain the best available personnel
for positions of substantial responsibility and to provide additional
incentive to employees and consultants to promote the success of the Company's
business. The 1993 Plan is presently being administered by the Board of
Directors, which determines the optionees and the terms of options granted,
including the exercise price, number of shares subject to the option and the
exercisability thereof.
 
  The term of an option granted under the 1993 Plan is stated in the option
agreement. However, the term of an incentive stock option may not exceed 10
years and, in the case of an incentive or nonstatutory stock option granted to
an optionee who, at the time of grant, owns stock representing more than 10%
of the Company's outstanding capital stock, the term of such option may not
exceed five years. Options granted under the 1993 Plan vest and become
exercisable as set forth in each option agreement. In general, no option may
be transferred by the optionee other than by will or the laws of descent or
distribution, and each option may be exercised, during the lifetime of the
optionee, only by such optionee. An optionee whose relationship with the
Company or any related corporation ceases for any reason (other than by death
or total and permanent disability) may exercise options in the three month
period following such cessation, unless such options terminate or expire
sooner (or for nonstatutory stock options later), by their terms, but only to
the extent the option had vested on such date of cessation. In the event of
death or total and permanent disability, the option may be exercised in the
six month period following the date of death or total and permanent disability
unless such options terminate or expire sooner (or for nonstatutory stock
options, later), but only to the extent the option had vested as of six months
after the date of death or disability. In the event of a merger of the Company
with or into another corporation, all outstanding options may be
 
                                      43
<PAGE>
 
assumed or an equivalent option may be substituted by the surviving entity. If
such options are not assumed or substituted, such options will become
exercisable as to all of the shares subject to the options, including shares
as to which they would not otherwise be exercisable. In the event that options
become exercisable in lieu of assumption or substitution, the Board of
Directors will notify optionees that all options will be fully exercisable for
a period of 15 days, after which such options will terminate. The Board of
Directors determines the exercise price of options granted under the 1993 Plan
at the time of grant, provided that the exercise price of all incentive stock
options must be at least equal to the fair market value of the shares on the
date of grant. With respect to any participant who owns stock possessing more
than 10% of the voting rights of the Company's outstanding capital stock, the
exercise price of any incentive stock option granted must equal at least 110%
of the fair market value on the grant date. The consideration for exercising
any incentive stock option or any nonstatutory stock option may consist of
cash, check, promissory note, delivery of already-owned shares of the
Company's Common Stock subject to certain conditions, delivery of a properly
executed exercise notice together with irrevocable instructions to a broker to
promptly deliver to the Company the amount of sale or loan proceeds required
to pay the exercise price, a reduction in the amount of any Company liability
to an optionee, or any combination of the foregoing methods of payment or such
other consideration or method of payment to the extent permitted under
applicable law. No incentive stock options may be granted to a participant
that when aggregated with all other incentive stock options granted to such
participant, would have an aggregate fair market value in excess of $100,000
becoming exercisable in any calendar year. No employee may be granted, in any
fiscal year of the Company, options to purchase more than 250,000 shares (or
1,000,000 shares in the case of an employee's initial year of employment). The
1993 Plan will terminate in October 2003, unless sooner terminated by the
Board of Directors.
 
  As of September 30, 1997, 723,604 shares of Common Stock had been issued
upon the exercise of options granted under the 1993 Plan, options to purchase
1,406,908 shares of Common Stock at a weighted average exercise price of $1.56
per share were outstanding and 2,160,884 shares remain available for future
option grants under the 1993 Plan.
 
  1997 EMPLOYEE STOCK PURCHASE PLAN. The Purchase Plan was adopted by the
Board of Directors and approved by the Company's stockholders in November
1997. A total of 600,000 shares of Common Stock has been reserved for issuance
under the Purchase Plan, together with an annual increase to the number of
shares reserved thereunder on each anniversary date of the adoption of the
Purchase Plan equal to the lesser of (i) 200,000 shares, (ii) one percent of
the outstanding shares of the Company on such date or (iii) a lesser amount
determined by the Board of Directors. The Purchase Plan, which is intended to
qualify under Section 423 of the Code, will be administered by the Board of
Directors and may be administered by a committee appointed by the Board of
Directors. Employees (including officers and employee directors of the
Company, but excluding 5% stockholders) are eligible to participate if they
are customarily employed for at least 20 hours per week and for more than five
months in any calendar year. The Purchase Plan permits eligible employees to
purchase Common Stock through payroll deductions, which may not exceed 15% of
an employee's compensation. The Purchase Plan will be implemented in a series
of overlapping offering periods, each to be approximately 24 months in
duration. The initial offering period under the Purchase Plan will begin on
the effective date of this Offering and subsequent offering periods will begin
on the first trading day on or after February 1 and August 1 of each year.
Each participant will be granted an option on the first day of the offering
period and such option will be automatically exercised on the last day of each
semi-annual period throughout the offering period. If the fair market value of
the Common Stock on any purchase date is lower than such fair market value on
the start date of that offering period, then all participants in that offering
period will be automatically withdrawn
 
                                      44
<PAGE>
 
from such offering period and re-enrolled in the immediately following
offering period. The purchase price of the Common Stock under the Purchase
Plan will be equal to 85% of the lesser of the fair market value per share of
Common Stock on the start date of the offering period or on the date on which
the option is exercised. Employees may end their participation in an offering
period at any time during that period, and participation ends automatically on
termination of employment with the Company. In the event of a proposed
dissolution or liquidation of the Company, the offering periods terminate
immediately prior to the consummation of the proposed action, unless otherwise
provided by the Board of Directors. In the event of a proposed sale of all or
substantially all of the Company's assets or the merger of the Company with or
into another corporation, each outstanding option will be assumed or an
equivalent option substituted by the successor, parent or subsidiary. If the
successor corporation refuses to assume or substitute the option, then the
offering period in progress will be shortened by setting a new exercise date
that is the day before the sale or merger and the offering period in progress
will end on the new exercise date. In the event of a dissolution, liquidation,
merger or asset sale, each participant will be notified at least ten business
days prior to the new exercise date, and unless such participant ends his or
her participation, the option will be exercised automatically on the new
exercise date. The Purchase Plan will terminate in November 2007, unless
sooner terminated by the Board of Directors.
 
  1997 DIRECTOR OPTION PLAN. The Director Plan, which becomes effective upon
the effective date of this Offering, was adopted by the Board of Directors and
approved by the Company's stockholders in November 1997. A total of 200,000
shares of Common Stock has been reserved for issuance under the Director Plan.
The option grants under the Director Plan are automatic and nondiscretionary,
and the exercise price of the options will be equal to 100% of the fair market
value of the Common Stock on the grant date. The Director Plan provides for
the grant of an initial option to purchase 25,000 shares to each nonemployee
director of the Company upon the effective date of this Offering at a per
share exercise price equal to the initial public offering price. In addition,
each new nonemployee director joining the Board of Directors after this
Offering will automatically be granted an option to purchase 25,000 shares of
Common Stock upon joining the Board of Directors. Subsequently, each
nonemployee director will automatically be granted an additional option to
purchase 5,000 shares of Common Stock at the next meeting of the Board of
Directors following the annual meeting of stockholders in each year beginning
with the 1998 Annual Meeting of Stockholders, if on such date such director
has served on the Board of Directors for the preceding six months. The term of
such options is ten years, provided that such options will terminate three
months following the termination of the optionee's status as a director (or 12
months if the termination is due to death or disability). The initial 25,000
share grants vest at a rate of 25% on the first anniversary of the date of
grant and at a rate of 1/48th of the shares subject to the option per month
thereafter. The subsequent 5,000 share grants vest at a rate of 1/48th of the
shares subject to the option per month following the date of grant. In the
event of a merger of the Company with or into another corporation, all
outstanding options may be assumed or an equivalent option may be substituted
by the surviving entity. If such options are not assumed or substituted, such
options will become exercisable as to all of the shares subject to the
options, including shares as to which they would not otherwise be exercisable.
In the event that options become exercisable in lieu of assumption or
substitution, the Board of Directors will notify optionees that all options
will be fully exercisable for a period of 30 days, after which such options
will terminate. The Director Plan will terminate upon the tenth anniversary of
the effective date of the initial public offering, unless sooner terminated by
the Board of Directors.

401(K) PLAN
 
  As of June 1, 1991, the Company adopted a tax-qualified employee savings and
retirement plan (the "401(k) Plan") covering the Company's employees. Pursuant
to the 401(k) Plan, eligible employees may elect to reduce their current
compensation by up to the lesser of 15% of their annual compensation or the
statutorily prescribed annual limit ($9,500 in calendar years 1996 and 1997)
and have the amount of such reduction contributed to the 401(k) Plan. The
Company currently matches contributions by employees up to 25% of the
individual employee's contributions. The trustees under the 401(k) Plan, at
the direction of each participant, invest the assets of the 401(k) Plan in
designated investment options. The 401(k) Plan is intended to qualify under
Section 401 of the Code, so that contributions to the 401(k) Plan, and income
earned on the 401(k) Plan contributions, are not taxable until withdrawn, and
so that the contributions by the Company will be deductible when made.
 
EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS
 
  Pursuant to the terms of a September 5, 1996 amendment to his offer letter,
Jeffrey A. Lewis, Vice President, Marketing of the Company, is also entitled,
under specified conditions, to partial acceleration of vesting of an option to
purchase 253,705 shares of the Company's Common Stock. In the event Mr. Lewis'
employment is terminated other than for cause following a change of control of
the Company, 25% of Mr. Lewis' original option grant will vest and become
immediately exercisable.
 
  In June 1997, the Company granted to Robert D. Selvi, Vice President Finance
and Chief Financial Officer of the Company, an incentive stock option to
purchase 251,693 shares of Common Stock at $4.50 per share, subject to the
vesting provisions under the 1993 Plan. Pursuant to a severance agreement
entered into with Mr. Selvi, in the event that Mr. Selvi is terminated other
than voluntarily or for cause, he shall be entitled to receive (i) his base
salary, as then in effect, for a period of six months plus any targeted bonus
amount pro rated for such six months period as determined by the Board of
Directors and (ii) the option granted to him for 251,693 shares of Common
Stock will continue to vest for an additional 18 months following such
termination. Termination other than for cause includes constructive
termination resulting from (i) the reduction of rate of compensation, (ii) the
reduction of the scope of Mr. Selvi's engagement, (iii) the requirement that
Mr. Selvi provide services at a location more than 25 miles from the Company's
current principal office location or from Mr. Selvi's residence or (iv)
subjection of Mr. Selvi to unreasonable working conditions. In addition, if
there is a change of control of the Company and Mr. Selvi is terminated other
than for cause within six months following the effective date of such change
of control, Mr. Selvi will be entitled to a cash payment of an amount equal to
six months of his base salary as then in effect plus any targeted bonus amount
pro rated for such six month period and the option granted to him for 251,693
shares will be 100% vested and exercisable.
 
  Pursuant to the terms of his July 31, 1997 offer letter, Larry J. Fagg, Vice
President, Worldwide Sales of the Company is entitled, under specified
conditions, to partial acceleration of vesting of options to purchase 109,432
shares of the Company's Common Stock and certain severance and benefit
payments. In the event Mr. Fagg's employment is terminated other than for
cause following a change of control of the Company, 50% of the remaining
unvested shares of Mr. Fagg's original option grant will vest and become
immediately exercisable, Mr. Fagg will be entitled to receive a severance
payment equal to six month's base salary and commissions at target and he will
be entitled to continue to participate in the Company's benefit programs for a
period of six months after the effective date of his termination at no cost to
him. For purposes of Mr. Fagg's employment, a change in control of the Company
is defined as the acceptance by the Company of any offer that would result in
the acquiror owning more than 50% of the Company's assets or voting stock then
outstanding.

TRANSACTIONS WITH SYNOPSYS, INC.
 
  In December 1996, Synopsys purchased 841,448 shares of Series B Preferred
Stock of the Company at a purchase price of $3.77 per share. In connection
with such purchase, Synopsys was granted certain registration rights. See
"Description of Capital Stock--Registration Rights." The Company also granted
Synopsys a warrant to purchase 50,000 shares of Series B Preferred Stock (or
Common Stock in connection with an initial public offering) at a purchase
price of $3.77 per share, subject to adjustments for stock splits and the
like, as well as an additional variable amount of shares of Series B Preferred
Stock, at a price to be determined at
 
                                      47
<PAGE>
 
the time of issuance of such shares. The aggregate number of shares issuable
upon exercise of the warrant will be increased such that Synopsys will be able
to purchase additional shares to offset the dilution resulting from the
exercise of options to purchase Common Stock outstanding as of December 16,
1996. However, the aggregate number of shares that Synopsys may purchase
pursuant to the warrant will be limited to that number which if held would
give Synopsys an aggregate percentage ownership of 9.9% of the Company. On
November 17, 1997, Synopsys irrevocably exercised such warrant for 50,000
shares. This transaction will close immediately prior to the closing of this
Offering.
 
  In connection with such financing the Company granted to Synopsys, for so
long as Synopsys holds at least 420,000 of the Company's stock, the right to
receive notice of and to designate a representative to attend the Board of
Directors of the Company in a nonvoting, observer capacity, subject to
exclusion for discussions about matters involving Synopsys or any Synopsys'
competitor, where attendance could adversely affect attorney client privilege
between the Company and its attorneys or if, in the discretion of the Board of
Directors, where attendance would violate the fiduciary duties of the Board of
Directors. The observer rights granted to Synopsys will terminate upon the
consummation of the Offering.
 
  In December 1996, the Company also entered into an OEM Agreement with
Synopsys (the "OEM Agreement"), pursuant to which the Company granted Synopsys
a nonexclusive, nontransferable, worldwide right to distribute certain of the
Company's technology, including certain products that are integrated with some
of Synopsys' technology. Synopsys is obligated to pay a royalty to the Company
in connection with the OEM Agreement, and Synopsys was granted the right to be
the exclusive seller of the products integrating both the Company's and
Synopsys' technology. A portion of such royalty payments were payable in
advance, with subsequent royalties due to the Company to offset such initial
payment. The Company does not anticipate recognizing any revenue under the OEM
Agreement. Under the agreement, Synopsys granted the Company a nonexclusive,
nontransferable license to use certain Synopsys products in connection
therewith. Pursuant to the OEM Agreement, the Company agreed to provide
certain engineering and porting services, as well as maintenance and support
services. The OEM Agreement has a five-year term and may be extended for an
additional 18 months. The OEM Agreement may be terminated by either party upon
the breach by the other party, or if the other party becomes insolvent, fails
to pay its debts or perform its obligations as they mature, admits in writing
to its insolvency or inability to pay its debts or perform its obligations as
they mature, or makes an assignment for the benefit of creditors. In addition,
either party may terminate the OEM Agreement upon eighteen months' written
notice to the other party. In the event that the Company terminates the OEM
Agreement as a result of a change of control of the Company, Synopsys will,
upon the occurrence of certain events, be entitled to have access to the
Company's source code for those products of the Company that are marketed by
Synopsys.
 
  The Company believes that all of the transactions set forth above were made
on terms no less favorable to the Company than could have been obtained from
unaffiliated third parties. All future transactions, including loans, between
the Company and its officers, directors, principal stockholders and their
affiliates will be approved by a majority of the Board of Directors, including
a majority of the independent and disinterested outside directors, and will
continue to be on terms no less favorable to the Company than could be
obtained from unaffiliated third parties.

                         DESCRIPTION OF CAPITAL STOCK
 
  Upon the completion of this Offering, the Company will be authorized to
issue 50,000,000 shares of Common Stock, $0.001 par value, and 5,000,000
shares of undesignated Preferred Stock, $0.001 par value.
 
COMMON STOCK
 
  As of September 30, 1997, there were 9,079,953 (including shares resulting
from the exercise of the warrant described below) shares of Common Stock
outstanding held of record by approximately 67 stockholders. As of September
30, 1997, options to purchase an aggregate of 1,406,908 shares of Common Stock
were also outstanding. See "Management--Stock Plans."
 
  The holders of Common Stock are entitled to one vote per share on all
matters to be voted on by stockholders and have cumulative voting rights with
respect to the election of directors. Subject to the prior rights of holders
of Preferred Stock, if any, the holders of Common Stock are entitled to
receive such dividends, if any, as may be declared from time to time by the
Board of Directors in its discretion from funds legally available therefor.
Upon liquidation or dissolution of the Company, the remainder of the assets of
the Company will be distributed ratably among the holders of Common Stock
after payment of liabilities and the liquidation preferences of any
outstanding shares of Preferred Stock. The Common Stock has no preemptive or
other subscription rights and there are no conversion rights or redemption or
sinking fund provisions with respect to such shares. All of the outstanding
shares of Common Stock are, and the shares to be sold in this Offering will
be, fully paid and nonassessable.
 
PREFERRED STOCK
 
  Pursuant to the Company's Certificate of Incorporation effective after
conversion of previously outstanding shares of Preferred Stock into an
aggregate of 3,435,736 (assuming the exercise of the warrant described below)
shares of Common Stock which conversion will be effected simultaneously with
the consummation of this Offering, the Board of Directors has the authority
without further action by the stockholders to issue up to 5,000,000 shares of
Preferred Stock. The Board of Directors has the authority to issue such
Preferred Stock in one or more series and to fix the price, rights,
preferences, privileges and restrictions thereof, including dividend rights,
dividend rates, conversion rights, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares
constituting a series or the designation of such series, without any further
vote or action by the Company's stockholders. The issuance of Preferred Stock,
while providing desirable flexibility in connection with possible acquisitions
and other corporate purposes, could have the effect of delaying, deferring or
preventing a change in control of the Company without further action by the
stockholders and may adversely affect the market price of, and the voting and
other rights of, the holders of Common Stock. The Company has no current plans
to issue any shares of Preferred Stock.
 
WARRANTS
 
  As of September 30, 1997, a warrant was outstanding to purchase an aggregate
of 50,000 shares of the Company's Series B Preferred Stock at an exercise
price of $3.77 per share and an additional, variable amount of Preferred Stock
at the initial public offering price less the underwriting discount. The
holder of such warrant has irrevocably indicated its intention to exercise the
warrant solely for such 50,000 shares upon the closing of this Offering.
 
                                      51
<PAGE>
 
CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BYLAWS
 
  The Company's Certificate of Incorporation provides for cumulative voting
for the election of directors. Cumulative voting provides that each share of
stock normally having one vote is entitled to a number of votes equal to the
number of directors to be elected. A stockholder may then cast all such votes
for a single candidate or may allocate them among as many candidates as the
stockholder may choose. In the absence of cumulative voting, the holders of a
majority of the shares present or represented at a meeting in which directors
are to be elected would have the power to elect all the directors to be
elected at such meeting, and no person could be elected without the support of
holders of a majority of the shares present or represented at such meeting.
Section 141 of the Delaware General Corporation Law provides that a director
elected by cumulative voting generally may not be removed without cause if the
number of votes cast against removal would be sufficient to elect such
director under cumulative voting.
 
  The Company's Bylaws establish an advance notice procedure for stockholder
proposals to be brought before an annual meeting of stockholders of the
Company, including proposed nominations of persons for election to the Board
of Directors. Stockholders at an annual meeting may only consider proposals or
nominations specified in the notice of meeting or brought before the meeting
by or at the direction of the Board of Directors or by a stockholder who was a
stockholder of record on the record date for the meeting, who is entitled to
vote at the meeting and who has given to the Company's Secretary timely
written notice, in proper form, of the stockholder's intention to bring that
business before the meeting. Although the Bylaws do not give the Board of
Directors the power to approve or disapprove stockholder nominations of
candidates or proposals regarding other business to be conducted at a special
or annual meeting of the stockholders, the Bylaws may have the effect of
precluding the conduct of certain business at a meeting if the proper
procedures are not followed or may discourage or defer a potential acquiror
from conducting a solicitation of proxies to elect its own slate of directors
or otherwise attempting to obtain control of the Company.
 
  Under Delaware law, a special meeting of stockholders may be called by the
Board of Directors or by any other person authorized to do so in the
Certificate of Incorporation or the Bylaws. The Company's Bylaws authorize the
Board of Directors, the Chairman of the Board (or the Chief Executive Officer
in the Chairman's absence), or one or more stockholders holding in the
aggregate 10% of votes, to call a special meeting of stockholders. However,
the Board of Directors may amend the Bylaws at any time to eliminate the right
to call a special meeting of stockholders. The elimination of the right of
stockholders to call a special meeting would mean that a stockholder could not
force stockholder consideration of a proposal over the opposition of the Board
of Directors by calling a special meeting of stockholders prior to such time
as the Board of Directors believed such consideration to be appropriate or
until the next annual meeting provided that the requestor met the notice
requirements. The restriction on the ability of stockholders to call a special
meeting would mean that a proposal to replace the Board could be delayed until
the next annual meeting.
 
  Under Delaware law, stockholders may execute an action by written consent in
lieu of a stockholder meeting. Delaware law permits a corporation to eliminate
such actions by written consent. Elimination of written consents of
stockholders may lengthen the amount of time required to take stockholder
actions since certain actions by written consent are not subject to the
minimum notice requirement of a stockholders' meeting. The elimination of
stockholders' written consents, however, deters hostile takeover attempts.
Without the availability of stockholder's actions by written consent, a holder
or group of holders controlling a majority in interest of the Company's
capital stock would not be able to amend the Company's Bylaws or remove
directors pursuant to a stockholder's written consent. Any such holder or
group of holders would have to call a stockholders' meeting and wait until the
notice periods determined
 
                                      52
<PAGE>
 
by the Board of Directors pursuant to the Company's Bylaws prior to taking any
such action. The Company's Certificate of Incorporation provides for the
elimination of actions by written consent of stockholders upon the closing of
this Offering.
 
CERTAIN PROVISIONS OF DELAWARE LAW
 
  Upon completion of the reincorporation, the Company will be subject to
Section 203 of the Delaware General Corporation Law ("Section 203"). In
general, Section 203 prohibits a publicly held Delaware corporation from
engaging in various "business combination" transactions with any "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an "interested stockholder," unless (i) prior to such
date, the Board of Directors of the corporation approved either the business
combination or the transaction which resulted in the stockholder becoming an
interested stockholder, (ii) upon consummation of the transaction which
resulted in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned by (a) persons
who are directors and also officers and (b) employee stock plans in which
employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or
exchange offer, or (iii) on or subsequent to such date the business
combination is approved by the board of directors and authorized at an annual
or special meeting of stockholders by the affirmative vote of at least 66 2/3%
of the outstanding voting stock which is not owned by the interested
stockholder. Section 203 defines business combination to include: (i) any
merger or consolidation involving the corporation and the interested
stockholder; (ii) any sale, transfer, pledge or other disposition involving
the interested stockholder of 10% or more of the assets of the corporation;
(iii) subject to certain exceptions, any transaction that results in the
issuance or transfer by the corporation of any stock of the corporation to the
interest stockholder; (iv) any transaction involving the corporation that has
the effect of increasing the proportionate share of the stock of any class or
series of the corporation beneficially owned by the interested stockholder; or
(v) the receipt by the interested stockholder of the benefit of any loans,
advances guarantees, pledges or other financial benefits provided by or
through the corporation. In general, Section 203 defines an interested
stockholder as any entity or person who, together with affiliates and
associates, beneficially owns (or within three years did beneficially own) 15%
or more of a corporation's voting stock. The statute could prohibit or delay
mergers or other takeover or change in control attempts with respect to the
Company and, accordingly, may discourage attempts to acquire the Company.
 
REGISTRATION RIGHTS
 
  The holders of approximately 3,435,736 shares of Common Stock (issuable upon
conversion of Preferred Stock or exercise of a warrant) and their permitted
transferees (the "Holders") are entitled to certain rights with respect to the
registration of such shares ("Registrable Securities") under the Securities
Act. Under the terms of an agreement between the Company and the Holders, the
holders of at least 40% of the Registrable Securities may require, on two
occasions after six months from the effective date of this Offering, that the
Company use its best efforts to register the Registrable Securities for public
resale. In addition, if the Company proposes to register any of its securities
under the Securities Act, either for its own account or for the account of
other security holders exercising registration rights, the Holders are
entitled to notice of such registration and are entitled to include shares of
such Common Stock therein. The holders of Registrable Securities may also
require the Company, no more once in any 12 month period, to register all or a
portion of their Registrable Securities on Form S-3 under the Securities Act
when use of such form becomes available to the Company. All such registration
 
                                      53
<PAGE>
 
rights are subject to certain conditions and limitations, including the right
of the underwriters of an offering to limit the number of shares to be included
in such registration. In addition, the Company need not effect a registration
within three months following a previous registration or six months following
this Offering or more than the earlier of five years after the closing of this
Offering or such time as all Holders may sell under Rule 144 in a three month
period all shares of Common Stock to which such registration rights apply and
the Holder owns less than 2% of the Company's outstanding stock.
 
TRANSFER AGENT
 
  The transfer agent for the Common Stock is the First National Bank of Boston.
Its address is 150 Royall Street, Canton, Massachusetts 02021, and its
telephone number is (617) 575-3120.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this Offering, there has been no market for the Common Stock of the
Company. Sales of a substantial number of shares of Common Stock in the public
market following this Offering could adversely affect the prevailing market
prices from time to time. Furthermore, since only a limited number of shares
will be available for sale shortly after this Offering because of certain
contractual and legal restrictions on resale (as described below), sales of
substantial amounts of Common Stock of the Company in the public market after
the restrictions lapse could adversely affect the prevailing market price and
the ability of the Company to raise equity capital in the future.
 
  Upon completion of this Offering, the Company will have outstanding an
aggregate of 11,979,953 shares of Common Stock (based upon shares outstanding
at September 30, 1997), assuming no exercise of the Underwriters' over-
allotment option. Of these shares, all of the shares sold in this Offering
will be freely transferable without restriction or registration under the
Securities Act, except for any shares purchased by an existing "affiliate" of
the Company, as that term is defined in Rule 144 (an "Affiliate"), which
shares will be subject to the resale limitations of Rule 144. The remaining
9,079,953 shares of Common Stock held by existing stockholders are "restricted
shares" as that term is defined in Rule 144 (the "Restricted Shares").
Restricted Shares may be sold in the public market only if registered or if
they qualify for an exemption from registration under Rule 144, Rule 144(k) or
Rule 701, which rules are summarized below. As a result of the contractual
restrictions described below and the provisions of Rule 144, Rule 144(k) and
Rule 701, the Restricted Shares will be available for sale in the public
market as follows: (i) no shares will be available for immediate sale on the
date of this Prospectus; (ii) approximately 9,029,953 shares will become
eligible for sale 180 days after the date of this Prospectus (assuming no
release from the lock-up agreements) upon expiration of lock-up agreements;
and (iii) approximately 50,000 shares will become eligible for sale one year
after the date of this Prospectus.
 
  All officers, directors, optionholders and substantially all stockholders of
the Company have agreed not to sell, or otherwise transfer any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock for a period of 180 days after the date of this Prospectus
(without, in most cases, the prior written consent of Deutsche Morgan Grenfell
Inc.). Deutsche Morgan Grenfell 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. Deutsche Morgan Grenfell Inc. currently has no plans to
release any portion of the securities subject to such lock-up agreements.
 
  In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least one year (including
the holding period of any prior owner except an Affiliate) would be entitled
to sell within any three month period a number of shares that does not exceed
the greater of: (i) one percent of the number of shares of Common Stock then
outstanding (which will equal approximately 119,799 shares immediately after
this Offering); or (ii) the average weekly trading volume of the Common Stock
on the Nasdaq National Market during the four calendar weeks preceding the
filing of a Form 144 with respect to such sale. Sales under Rule 144 are also
subject to certain manner of sale provisions and notice requirements and to
the availability of current public information about the Company. Under Rule
144(k), a person who is not deemed to have been an Affiliate at any time
during the 90 days preceding a sale, and who has beneficially owned the shares
proposed to be sold for at least two years (including the holding period of
any prior owner except an Affiliate), is entitled to sell such shares without
complying with the manner of sale, public information, volume
 
                                      55

limitation or notice provisions of Rule 144; therefore, unless otherwise
restricted, "144(k) shares" may be sold immediately upon the completion of this
Offering. In general, under Rule 701 of the Securities Act as currently in
effect, any employee, consultant or advisor of the Company who purchases shares
from the Company in connection with a compensatory stock or option plan or
other written agreement is eligible to resell such shares 90 days after the
effective date of this Offering in reliance on Rule 144, but without compliance
with certain restrictions, including the holding period, contained in Rule 144.
 
  Upon completion of this Offering, the holders of 3,435,736 shares of Common
Stock issuable upon conversion of Preferred Stock or exercise of a warrant, or
their transferees, will be entitled to certain rights with respect to the
registration of such shares under the Securities Act. See "Description of
Capital Stock--Registration Rights." Registration of such shares under the
Securities Act would result in such shares becoming freely tradable without
restriction under the Securities Act (except for shares purchased by
Affiliates) immediately upon the effectiveness of such registration.
 
  The Company intends to file a registration statement on Form S-8 under the
Securities Act covering shares of Common Stock reserved for issuance under the
Company's stock plans and subject to outstanding options under the 1993 Plan.
See "Management--Stock Plans." Such registration statement is expected to be
filed and become effective as soon as practicable after the effective date of
this Offering. Shares of Common Stock issued upon exercise of options under the
Form S-8 will be available for sale in the public market, subject to Rule 144
volume limitations applicable to Affiliates and subject to the contractual
restrictions described above. At September 30, 1997, options to purchase
1,406,908 shares of Common Stock were outstanding, of which options to purchase
approximately 292,173 shares were then vested and exercisable. Beginning 180
days after the effective date of this Offering, approximately 295,468 shares
issuable upon the exercise of vested stock options will become eligible for
sale in the public market, if such options are exercised.

which will be filed as an exhibit to the Company's Registration Statement of

  The Underwriting Agreement provides that the obligations of the several
Underwriters thereunder are subject to the approval of certain legal matters by
counsel and to various other conditions.
 
  The Representatives have advised the Company that the Underwriters initially
propose to offer the Common Stock to the public on the terms set forth on the
cover page of this Prospectus. The Underwriters may allow selected dealers (who
may include the Underwriters) a concession not in excess of $     a share under
the initial public offering price. The selected dealers may reallow a
concession not in excess of $     a share to other dealers and other selling
terms may be changed by the Representatives. The Common Stock is offered
subject to receipt and acceptance by the Underwriters, and to certain other
conditions, including the right to reject orders in whole or in part. The
Underwriters do not intend to sell any of the shares of Common Stock offered
hereby to accounts for which they exercise discretionary authority.
 
  Pursuant to the Underwriting Agreement, the Company and the Selling
Stockholders have granted to the Underwriters an option to purchase up to
65,000 and 370,000 additional shares of Common Stock, respectively, to cover
over-allotments, if any, at the initial public offering price, less the
underwriting discount set forth on the cover page of this Prospectus. Such
option is exercisable for 30 days from the date of this Prospectus. To the
extent such option is exercised, each Underwriter will be committed, subject to
certain conditions, to purchase approximately the same percentage of such
additional shares of Common Stock as the number set forth next to such
Underwriter's name in the preceding table bears to the total number of shares
of Common Stock offered hereby. The Selling Stockholders will be obligated,
pursuant to the option, to sell such shares to the Underwriters.
 
  See "Shares Eligible for Future Sale" for a description of certain
arrangements by which all officers, directors, optionholders and substantially
all stockholders of the Company have agreed not to sell or otherwise dispose of
Common Stock or convertible securities of the Company for up to 180 days after
the date of the final Prospectus without the prior consent of Deutsche Morgan
Grenfell Inc. The Company has agreed in the Underwriting Agreement that it will
not, directly or indirectly, without the prior written consent of Deutsche
Morgan Grenfell Inc.,
 
                                       57

contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase, or
otherwise transfer or dispose of any shares of Common Stock or any securities
convertible into or exchangeable for Common Stock, for a period of 180 days
after the date of the final Prospectus without the consent of Deutsche Morgan
Grenfell Inc., except under certain circumstances.
 
  The Underwriting Agreement provides that the Company, and the Selling
Stockholders in the event the over-allotment option is exercised, will
indemnify the several Underwriters against certain liabilities, including
civil liabilities under the Securities Act, or will contribute to payments the
Underwriters may be required to make in respect thereof.
 
  Prior to this Offering, there has been no public market for the Common
Stock. The initial public offering price will be determined by negotiation
between the Company and the Representatives. The principal factors to be
considered in determining the initial public offering price include the
information set forth in this Prospectus and otherwise available to the
Representatives; the history and the prospects for the industry in which the
Company competes; the ability of the Company's management; the prospects for
future earnings of the Company; the present state of the Company's development
and its current financial condition; the general condition of the securities
markets at the time of this Offering; and the recent market prices of, and the
demand for, publicly traded common stock of generally comparable companies.
Each of the Representatives has informed the Company that it currently intends
to make a market in the shares subsequent to the effectiveness of this
Offering, but there can be no assurance that the Representatives will take any
action to make a market in any securities of the Company.
 
  At the request of the Company, the Underwriters have reserved for sale at
the initial public offering price to persons designated by the Company a
number of shares of Common Stock not to exceed five percent of the total
number of shares of Common Stock in this Offering. The number of shares
available for sale to the general public will be reduced to the extent such
persons purchase these shares.
 
  Certain persons participating in this Offering may over-allot or effect
transactions which stabilize, maintain or otherwise affect the market price of
the Common Stock at levels above those which might otherwise prevail in the
open market, including by entering stabilizing bids, effecting syndicate
covering transactions or imposing penalty bids. A stabilizing bid means the
placing of any bid or effecting of any purchase for the purpose of pegging,
fixing or maintaining the price of the Common Stock. A syndicate covering
transaction means the placing of any bid on behalf of the underwriting
syndicate or the effecting of any purchase to reduce a short position created
in connection with this Offering. A penalty bid means an arrangement that
permits the Underwriters to reclaim a selling concession from a syndicate
member in connection with this Offering when shares of Common Stock sold by
the syndicate member are purchased in syndicate covering transactions. Such
transactions may be effected on the Nasdaq Stock Market, in the over-the-
counter market or otherwise. Such stabilizing, if commenced, may be
discontinued at any time.
 
                                 LEGAL MATTERS
 
  The validity of the Common Stock offered hereby will be passed upon for the
Company by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo
Alto, California 94304. Certain matters will be passed upon for the
Underwriters by Fenwick & West LLP, Palo Alto, California 94306.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
Artisan Components, Inc.
 
  We have audited the accompanying balance sheets of Artisan Components, Inc.
as of September 30, 1996 and 1997, and the related statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended September 30, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Artisan Components, Inc.
as of September 30, 1996 and 1997, and the results of its operations and its
cash flows for each of the three years in the period ended September 30, 1997,
in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. FORMATION AND BUSINESS OF THE COMPANY:
 
  Artisan Components, Inc. (formerly VLSI Libraries Incorporated) (the
"Company") was incorporated in April 1991 to develop high performance, low
power and high density embedded memories and other intellectual property
("IP") components for the design and manufacture of complex integrated
circuits ("ICs"). The Company licenses its products to semiconductor
manufacturers and fabless semiconductor companies for the design of IC used in
complex, high volume applications, such as portable computing devices,
cellular phones, consumer multimedia products, automotive electronics,
personal computers and workstations.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 USE OF ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the
reported period. Actual results could differ from those estimates.
 
 REVENUE AND COST OF REVENUE
 
  Revenue consists of license fees for the Company's IP component products.
Revenue from license fees is recognized based on the percentage of completion
method for the majority of the Company's contracts. Under this method,
provisions for estimated losses on uncompleted contracts are recognized in the
period in which the likelihood of such losses is determined. Under certain
contracts where the costs cannot be estimated, the completed contract method
is utilized.
 
  Cost of revenue is primarily comprised of salaries and benefits of employees
assigned to the contracts and is allocated based on the amount of time devoted
to each contract by the employees and includes an accrual for warranty costs.
 
 PRODUCT DEVELOPMENT
 
  Product development expenses are charged to operations as incurred.
 
 COMPUTATION OF NET INCOME (LOSS) PER SHARE
 
  Net income (loss) per share is computed using the weighted average number of
common and dilutive common equivalent shares outstanding during the period.
Dilutive common equivalent shares consist of the incremental common shares
issuable upon conversion of convertible preferred stock (using the "if
converted" method) and exercise of stock options and warrants (using the
treasury stock method) for all periods.
 
  The Company has computed common and common equivalent shares in determining
the number of shares used in calculating earnings per share for all periods
presented pursuant to the Securities and Exchange Commission Staff Accounting
Bulletin (SAB) No. 83. SAB 83 requires the Company to include all common
shares and all common equivalent shares issued

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
 
during the 12 month period preceding the filing date of an initial public
offering in its calculation of the number of shares used to determine net
income (loss) per share as if the shares had been outstanding for all periods
presented.
 
 CASH AND CASH EQUIVALENTS
 
  The Company considers all highly liquid investments with an original
maturity of three months or less at date of acquisition to be cash
equivalents. The Company maintains its cash and cash equivalents in accounts
with one major financial institution.
 
 MARKETABLE SECURITIES
 
  Marketable securities are classified as available-for-sale securities and
are carried at fair value, based on quoted market prices, with the unrealized
gains or losses, net of tax, reported in stockholders' equity. The amortized
cost of debt securities is adjusted for amortization of premiums and accretion
of discounts to maturity, both of which are included in interest income.
Realized gains and losses are recorded on the specific identification method.
 
 PROPERTY AND EQUIPMENT
 
  Property and equipment are stated at cost, less accumulated depreciation.
Property and equipment are depreciated on a straight line basis over their
respective estimated useful lives of three to five years. Leasehold
improvements are amortized on a straight line basis over the shorter of their
respective estimated useful lives or the terms of their respective leases.
Upon disposal, assets and related accumulated depreciation are removed from
the accounts and the related gain or loss is included in results from
operations.
 
 INCOME TAXES
 
  Deferred tax assets and liabilities are determined based on the difference
between the financial statement and tax bases of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected
to affect taxable income. Valuation allowances are established when necessary
to reduce deferred tax assets to the amounts expected to be realized.
 
 RECENT PRONOUNCEMENTS
 
  In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 128, Earnings Per Share ("SFAS
128"). SFAS 128 will change the computation, presentation and disclosure
requirements for earnings per share. SFAS 128 requires presentation of "basic"
and "diluted" earnings per share, as defined, on the face of the income
statement for all entities with complex capital structures. SFAS 128 is
effective for financial statements issued for periods ending after December
15, 1997 and requires restatement of all prior period earnings per share
amounts.
 
  In June 1997, the FASB issued SFAS No. 130, Reporting Comprehensive Income
("SFAS 130"). This statement establishes standards for reporting and display
of comprehensive income and its components (revenue, expenses and gains and
losses) in a full set of financial statements and becomes effective for fiscal
years beginning after December 31, 1997.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
 
  In June 1997, the FASB issued SFAS 131, "Disclosure About Segments of an
Enterprise and Related Information" ("SFAS 131"). SFAS 131 changes current
practice under SFAS 14 by establishing a new framework on which to base
segment reporting (referred to as the "management" approach) and also requires
interim reporting of segment information. It is effective for the Company's
fiscal year 1999.
 
  The Company is currently studying the impact of these pronouncements.
 
3. BUSINESS RISKS AND CREDIT CONCENTRATION:
 
  The Company operates in an intensely competitive industry which has been
characterized by rapid technological change, short product life cycles,
cyclical market patterns and heightened foreign and domestic competition.
Significant technological changes in the industry could affect operating
results adversely.
 
  The Company markets and sells its technology to a narrow base of customers
and generally does not require collateral. At September 30, 1997, four
customers accounted for 36%, 20%, 15% and 14%, respectively, of contract
receivables. At September 30, 1996, five customers accounted for 24%, 24%,
15%, 12% and 12%, respectively, of contract receivables.
 
  As of September 30, 1997, the Company's cash and cash equivalents were
deposited with one major financial institution in the form of demand deposits
and money market accounts.
 
  Financial instruments that potentially subject the Company to concentrations
of credit risk comprise principally cash and cash equivalents, marketable
securities and contract receivables. The Company invests its excess cash
primarily in U.S. government agency and treasury notes that mature within two
years.
 
4. CONTRACT RECEIVABLES:
 
  Contract receivables were comprised of the following (in thousands):

offering. The Company has reserved 3,385,736 shares of Common Stock in the

of Directors and the major Common Stockholder has the right to elect two
members of the Board of Directors. The remaining director is elected by

  The holders of Series A and Series B Preferred Stock are entitled to a
preference in liquidation to Common Stockholders of $1.5461 and $3.77 per
share, respectively, plus declared but unpaid dividends. After the above
amounts have been paid on the Preferred Stock, the remaining assets are
distributed to the holders of the Common Stock. If liquidation occurs prior to

25% rate of return on the original purchase price, compounded annually, from
the date of issuance.

 Stock Compensation
 
  The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards No. 123 ("SFAS No. 123"), "Accounting for
Stock-Based Compensation." Accordingly, no compensation cost has been
recognized for the 1993 Plan. The effect on fiscal 1996 and 1997 net income,
had compensation cost for the 1993 Plan been determined based on the fair
value at the grant date for awards consistent with the provisions of SFAS No.
123, would not result in a significant difference from the reported net income
for 1996 and 1997. However, such difference may not be representative of
future compensation cost because options vest over several years and
additional grants are made each year.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  As permitted by Section 204(a) of the California General Corporation Law,
the Registrant's Amended and Restated Articles of Incorporation eliminate a
director's personal liability for monetary damages to the Registrant and its
shareholders arising from a breach or alleged breach of the director's
fiduciary duty, except for liability arising under Sections 310 and 316 of the
California General Corporation Law or liability for (i) acts or omissions that
involve intentional misconduct or knowing and culpable violation of law, (ii)
acts or omissions that a director believes to be contrary to the best
interests of the Registrant or its shareholders or that involve the absence of
good faith on the part of the director, (iii) any transaction from which a
director derived an improper personal benefit, (iv) acts or omissions that
show a reckless disregard for the director's duty to the Registrant or its
shareholders in circumstances in which the director was aware, or should have
been aware, in the ordinary course of performing a director's duties, of a
risk of serious injury to the Registrant or its shareholders, (v) acts or
omissions that constitute an unexcused pattern of inattention that amounts to
an abdication of the director's duty to the Registrant or its shareholders,
(vi) interested transactions between the corporation and a director in which a
director has a material financial interest, and (vii) liability for improper
distributions, loans or guarantees. This provision does not eliminate the
directors' duty of care, and in appropriate circumstances equitable remedies
such as an injunction or other forms of non-monetary relief would remain
available under California law.
 
  Sections 204(a) and 317 of the California General Corporation Law authorize
a corporation to indemnify its directors, officers, employees and other agents
in terms sufficiently broad to permit indemnification (including reimbursement
for expenses) under certain circumstances for liabilities arising under the
Securities Act of 1933, as amended (the "Securities Act"). The Registrant's
Amended and Restated Articles of Incorporation and Bylaws contain provisions
covering indemnification to the maximum extent permitted by the California
General Corporation Law of corporate directors, officers and other agents
against certain liabilities and expenses incurred as a result of proceedings
involving such persons in their capacities as directors, officers employees or
agents, including proceedings under the Securities Act or the
 
                                     II-1
<PAGE>
 
Securities Exchange Act of 1934, as amended. Prior to the effective date of
this Offering, the Registrant will enter into indemnification agreements with
its directors and executive officers.
 
  In connection with its reincorporation in Delaware, the Registrant will be
subject to Section 145 of the Delaware General Corporation Law ("Section
145"). Section 145 permits indemnification of officers and directors of the
Company under certain conditions and subject to certain limitations. Section
145 also provides that a corporation has the power to maintain insurance on
behalf of its officers and directors against any liability asserted against
such person and incurred by him or her in 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 Section
145. Upon shareholder approval of such reincorporation, Article VI, Section
6.1, of the Registrant's Bylaws will provide for mandatory indemnification of
its directors and officers and permissible indemnification of employees and
other agents to the maximum extent not prohibited by the Delaware General
Corporation Law. The rights to indemnity thereunder continue as to a person
who has ceased to be a director, officer, employee or agent and inure to the
benefit of the heirs, executors and administrators of the person. In addition,
expenses incurred by a director or executive officer in defending any civil,
criminal, administrative or investigative action, suit or proceeding by reason
of the fact that he or she is or was a director or officer of the Registrant
(or was serving at the Registrant's request as a director or officer of
another corporation) shall be paid by the Registrant in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking
by or on behalf of such director or officer to repay such amount if it shall
ultimately be determined that he or she is not entitled to be indemnified by
the Registrant as authorized by the relevant section of the Delaware General
Corporation Law.
 
  As permitted by Section 102(b)(7) of the Delaware General Corporation Law,
the Registrant's Certificate of Incorporation provides that, pursuant to
Delaware law, its directors shall not be personally liable for monetary
damages for breach of the directors' fiduciary duty as directors to the
Registrant and its stockholders. This provision in the Certificate of
Incorporation does not eliminate the directors' fiduciary duty, and in
appropriate circumstances equitable remedies such as injunctive or other forms
of non-monetary relief will remain available under Delaware law. In addition,
each director will continue to be subject to liability for breach of the
director's duty of loyalty to the Registrant for acts or omission not in good
faith or involving international misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of Stock repurchases or redemptions that are
unlawful under Section 174 of the Delaware General Corporation Law. The
provision also does not affect a director's responsibilities under any other
law, such as the federal securities laws or state or federal environmental
laws. The Registrant has entered into indemnification agreements with each of
its directors and executive officers. Generally, the indemnification
agreements attempt to provide the maximum protection permitted by Delaware law
as it may be amended from time to time. Moreover, the indemnification
agreements provide for certain additional indemnification. Under such
additional indemnification provisions, however, an individual will not receive
indemnification for judgments, settlements or expenses if he or she is found
liable to the Registrant (except to the extent the court determines he or she
is fairly and reasonably entitled to indemnity for expenses), for settlements
not approved by the Registrant or for settlements and expenses if the
settlement is not approved by the court. The indemnification agreements
provide for the Registrant to advance to the individual any and all reasonable
expenses (including legal fees and expenses) incurred in investigating or
defending any such action, suit or proceeding. In order to receive an advance
of expenses, the individual must submit to the Registrant copies of invoices
presented to him or her for such expenses. Also, the individual must repay
such advances upon a final judicial decision that he or she is not entitled to
indemnification.
 
                                     II-2
<PAGE>
 
  The Registrant intends to enter into additional indemnification agreements
with each of its directors and executive officers to effectuate these
indemnity provisions and to purchase directors' and officers' liability
insurance.
 
  In addition to the foregoing, the Underwriting Agreement contains certain
provisions by which the Underwriters have agreed to indemnify the Registrant,
each person, if any, who controls the Registrant within the meaning of Section
15 of the Securities Act, each director of the Registrant, each officer of the
Registrant who signs the Registration Statement, with respect to information
furnished in writing by or on behalf of the Underwriters for use in the
Registration Statement.
 
  At present, there is no pending litigation or proceeding involving a
director, officer, employee or other agent of the Registrant in which
indemnification is being sought, nor is the Registrant aware of any threatened
litigation that may result in a claim for indemnification by any director,
officer, employee or other agent of the Registrant.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  Since September 30, 1994, the Registrant has issued and sold (without
payment of any selling commission to any person) the following unregistered
securities (as adjusted to reflect the two-for-one stock split effected in
January 1997 and the one-for-two reverse stock split effected in November
1997):
 
1. From September 30, 1994 to September 30, 1997, the Registrant issued and
   sold 723,604 shares of Common Stock to employees and consultants at prices
   ranging from $0.01 to $0.15 per share, upon exercise of stock options,
   pursuant to the Registrant's 1993 Stock Option Plan.
 
2. On September 30, 1997, the Registrant issued 20,613 shares of Common Stock
   to employees as a stock bonus.
 
3. On March 21, 1996, the Registrant issued and sold 2,263,805 shares of
   Series A Preferred Stock to a total of four investors for an aggregate
   purchase price of $3,500,059.64.
 
4. On December 17, 1996, the Registrant issued and sold 1,121,931 shares of
   Series B Preferred Stock to a total of five investors for an aggregate
   purchase price of $4,229,679.87 and issued to one investor for no
   additional consideration a warrant to purchase 50,000 shares of Series B
   Preferred Stock at an exercise price of $3.77 per share plus an additional
   variable amount of Preferred Stock.
 
  The issuances of securities set forth in paragraphs 1 and 2 above were
deemed to be exempt from the registration requirements of the Securities Act
in reliance on Rule 701 promulgated under Section 3(b) of the Securities Act
as transactions by an issuer pursuant to compensatory benefit plans and
contracts relating to compensation as provided under such Rule 701. The sales
of securities set forth in paragraphs 3 and 4 above were deemed to be exempt
from the registration requirements of the Securities Act in reliance on
Section 4(2) thereof, or Regulation D promulgated thereunder, as transactions
by an issuer not involving a public offering. The granting of Stock options
described in paragraph 1 above and the Stock bonus described in paragraph 2
above did not require registration under the Securities Act, or an exemption
therefrom, insofar as such grants did not involve a "sale" of securities as
such term is used in Section 2(3) of the Securities Act.
 
  The recipients of the securities in each of the transactions set forth in
paragraphs 1 through 4 above represented their intention to acquire such
securities for investment only and not with a view to or for sale in
connection with any distribution thereof, and appropriate legends were affixed
to the share certificates and instruments used in such transactions. All
recipients
 
                                     II-3
<PAGE>
 
received adequate information about the Registrant at the time of the
acquisition of such securities or had access, through employment or other
relationships with the Registrant, to such information.

ITEM 17. UNDERTAKINGS
 
  The Registrant hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 14, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

  The Registrant hereby undertakes that:
 
  (1) for purposes of determining any liability under the Securities Act, the
  information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in the form
  of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective;
 
  (2) For the purposes of determining any liability under the Securities Act,
  each post-effective amendment that contains a form of Prospectus shall be
  deemed to be a new Registration Statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
  In connection with our audits of the financial statements of Artisan
Components, Inc. as of September 30, 1996 and 1997, and for each of the three
years in the period ended September 30, 1997, which financial statements are
included in the Registration Statement, we have also audited the financial
statement schedule listed in Item 16.b. herein.
 
  In our opinion, the financial statement schedule, when considered in
relation to the basic financial statements taken as a whole, presents fairly,
in all material respects, the information required to be included therein.

     3.3  Artisan-California Options, Warrants, Stock Purchase Rights and
          ---------------------------------------------------------------
Convertible Securities.
- ---------------------- 

          (a) Upon the Effective Date of the Merger, the Surviving Corporation
shall assume the obligations of Artisan-California under, and continue, the
option plans (including without limitation the 1993 Stock Option Plan, 1997
Employee Stock Purchase Plan and 1997 Director Option Plan) and all other
employee benefit plans of Artisan-California.  Each outstanding and unexercised
option, warrant, other right to purchase, or security convertible into, Artisan-
California Common Stock or Artisan-California Preferred Stock (a "Right") shall
become, subject to the provisions in paragraph (c) hereof, an option, warrant,
right to purchase or a security convertible into the Surviving Corporation's
Common Stock or Preferred Stock, respectively, on the basis of one share of the
Surviving Corporation's Common Stock or Preferred Stock, as the case may be, for
each one share of Artisan-California Common Stock or Preferred Stock, as the
case may be, issuable pursuant to any such Right, on the same terms and
conditions and at an exercise price equal to the exercise price applicable to
any such Artisan-California Right at the Effective Date of the Merger.  This
paragraph 3.3(a) shall not apply to Artisan-California Common Stock or Preferred
Stock.  Such Common Stock and Preferred Stock are subject to paragraph 3.1 and
3.2, respectively, hereof.

          (b) A number of shares of the Surviving Corporation's Common Stock and
Preferred Stock shall be reserved for issuance upon the exercise of options,
warrants, stock purchase rights and convertible securities equal to the number
of shares of Artisan-California Common Stock and Artisan-California Preferred
Stock so reserved immediately prior to the Effective Date of the Merger.

          (c) The assumed Rights shall not entitle any holder thereof to a
fractional share upon exercise or conversion (unless the holder was entitled to
a fractional interest immediately prior to the Merger).  In lieu thereof, any
fractional share interests to which a holder of an assumed Right (other than an
option issued pursuant to Artisan-Delaware's 1993 Stock Option Plan, 1997
Employee Stock Purchase Plan and 1997 Director Option Plan) would otherwise be
entitled upon exercise or conversion shall be aggregated (but only with other
similar Rights which have the same per share terms).  To the extent that after
such aggregation, the holder would still be entitled to a fractional share with
respect thereto upon exercise or conversion, the holder shall be entitled upon
the exercise or conversion of all such assumed Rights pursuant to their terms
(as modified herein), to one full share of Common Stock or Preferred Stock in
lieu of such fractional share.  With respect to each class of such similar
Rights, no holder will be entitled to more than one full share in lieu of a
fractional share upon exercise or conversion.

     Notwithstanding the foregoing, with respect to options issued under the
Artisan-California 1993 Stock Option Plan, 1997 Employee Stock Purchase Plan and
1997 Director Option Plan that are assumed in the Merger, the number of shares
of Common Stock to which the holder would be otherwise entitled upon exercise of
each such assumed option following the Merger shall be rounded down to the
nearest whole number and the exercise price shall be rounded up to the nearest
whole cent.  In addition, no "additional benefits" (within the meaning of
Section 424(a)(2) of the Internal Revenue Code of 1986, as amended) shall be
accorded to the optionees pursuant to the assumption of their options.

     3.4  Artisan-Delaware Common Stock.  Upon the Effective Date of the Merger,
          -----------------------------                                         
each share of Common Stock, $.001 par value, of Artisan-Delaware issued and
outstanding immediately prior thereto shall, by virtue of the Merger and without
any action by Artisan-Delaware, the holder of such shares or any other person,
be canceled and returned to the status of authorized but unissued shares.

     3.5  Exchange of Certificates.  After the Effective Date of the Merger,
          ------------------------                                          
each holder of an outstanding certificate representing shares of Artisan-
California Common Stock or Preferred Stock may be asked to surrender the same
for cancellation to an exchange agent, whose name will be delivered to holders
prior to any requested exchange (the "Exchange Agent"), and each such holder
shall be entitled to receive in exchange therefor a certificate or certificates
representing the number of shares of the Surviving Corporation's Common Stock or
Preferred Stock, as the case may be, into which the surrendered shares were
converted as herein provided.  Until so surrendered, each outstanding
certificate theretofore representing shares of Artisan-California Common Stock
or Preferred Stock shall be deemed for all purposes to represent the number of
shares of the Surviving Corporation's Common Stock or Preferred Stock,
respectively, into which such shares of Artisan-California Common Stock or
Preferred Stock, as the case may be, were converted in the Merger.

     The registered owner on the books and records of the Surviving Corporation
or the Exchange Agent of any such outstanding certificate shall, until such
certificate shall have been surrendered for transfer or conversion or otherwise
accounted for to the Surviving Corporation or the Exchange Agent, have and be
entitled to exercise any voting and other rights with respect to and to receive
dividends and other distributions upon the shares of Common Stock or Preferred
Stock of the Surviving Corporation represented by such outstanding certificate
as provided above.

     Each certificate representing Common Stock or Preferred Stock of the
Surviving Corporation so issued in the Merger shall bear the same legends, if
any, with respect to the restrictions on transferability as the certificates
of Artisan-California so converted and given in exchange therefore, unless
otherwise determined by the Board of Directors of the Surviving Corporation in
compliance with appli  cable laws.

     If any certificate for shares of the Surviving Corporation's stock is to be
issued in a name other than that in which the certificate surrendered in
exchange therefor is registered, it shall be a condition of issuance thereof
that the certificate so surrendered shall be properly endorsed and otherwise in
proper form for transfer, that such transfer otherwise be proper and comply with
applicable securities laws and that the person requesting such transfer pay to
the Exchange Agent any transfer or other taxes payable by reason of issuance of
such new certificate in a name other than that of the registered holder of the
certificate surrendered or establish to the satisfaction of the Surviving
Corporation that such tax has been paid or is not payable.

     This corporation is authorized to issue two classes of shares to be
designated respectively Common Stock and Preferred Stock.  The total number of
shares of Common Stock this corporation shall have authority to issue is

Preferred") and 1,171,934 shares of Preferred Stock shall be designated Series B
Preferred Stock ("Series B Preferred"; and the Series B Preferred, collectively
with the Series A Preferred, the "Preferred Stock").


                                  ARTICLE V.

     The rights, preferences, privileges and restrictions granted to or imposed

<PAGE>
 
          The holders of the Series A Preferred and Series B Preferred shall be
entitled to receive, when and as declared by the Board of Directors, dividends
out of funds legally available therefore, prior and in preference to any
declaration or payment of any dividend (payable other than in Common Stock or
other securities and rights convertible into or entitling the holder thereof to
receive, directly or indirectly, additional shares of Common Stock of this
Corporation) on the Common Stock of this Corporation, at the rate of $1.5461 and
$3.77 per share, per annum, respectively.  Such dividends shall not be
cumulative and no right to such dividends shall accrue to holders of Preferred
Stock unless declared by the Board of Directors.  No dividends or other
distributions shall be made with respect to the Common Stock, other than
dividends payable solely in Common Stock, unless at the same time an equivalent
dividend with respect to the Preferred Stock has been paid or set apart.

     2.   Liquidation Preference.
          ---------------------- 

          In the event of any liquidation, dissolution, or winding up of the
Corporation ("Liquidation"), either voluntary or involuntary, distributions to
the shareholders of the Corporation shall be made in the following manner:

          (a) In the event of a Liquidation before March 20, 1999, the holders
of the 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 the Common Stock by reason of their ownership of such Preferred, an
amount equal to the greater of (i) $1.5461 per share of Series A Preferred or
$3.77 per share of Series B Preferred, respectively (as adjusted for stock
dividends, stock splits, stock combinations and the like, their respective
"Original Purchase Price"), plus an amount equal to a 25% rate of return
compounded annually on the Original Purchase Price from the date of issuance of
the first share of Series A Preferred or Series B Preferred, respectively,
issued to the date of Liquidation, plus all declared and unpaid dividends
thereon to the date fixed for distribution of assets, or (ii) the amount of any
such distribution as though the holders of the Series A Preferred or Series B
Preferred, respectively, were the holders of that number of shares of Common
Stock of the corporation into which their shares of Series A Preferred or Series
B Preferred, respectively, are convertible as of the record date fixed for
determination of the holders of Common Stock entitled to receive such
distribution (in the aggregate, the "Liquidation Preference Amount").  If upon a
Liquidation, the assets shall be insufficient to pay the holders of the Series A
Preferred and Series B Preferred the full Liquidation Preference Amount, the
holders of the Series A Preferred or Series B Preferred shall share ratably in
any distribution of assets according to the respective amounts which would be
payable in respect of the shares held by them upon such distribution if all
amounts payable on or with respect to said shares were paid in full.

          (b) In the event of a Liquidation occurring on or after March 20,
1999, the holders of the 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 the Common Stock by reason of their ownership of
such stock, an amount equal to the greater of (i) $1.5461 per share of each
share of Series A Preferred or $3.77 per share of each share of Series B
Preferred, respectively, then held by them (as adjusted for any stock dividends,
stock splits, recapitalizations, combinations, consolidations, or the like, with
respect to shares of the Preferred Stock), plus an amount equal to any declared
but unpaid 

                                      -2-
<PAGE>
 
dividends on the Preferred Stock, or (ii) the amount of any such distribution as
though the holders of the Series A Preferred or Series B Preferred were the
holders of that number of shares of Common Stock of the corporation into which
their shares of Series A Preferred and Series B Preferred, respectively, are
convertible as of the record date fixed for determination of the holders of
Common Stock entitled to receive such distribution (the "Preference"). If upon a
Liquidation, the assets shall be insufficient to pay the holders of the Series A
Preferred and Series B Preferred the full Preference, the holders of the Series
A Preferred or Series B Preferred shall share ratably in any distribution of
assets according to the respective amounts which would be payable in respect of
the shares held by them upon such distribution if all amounts payable on or with
respect to said shares were paid in full.

          (c) After payment or setting apart of payment of the Liquidation
Preference Amount or the Preference, as the case may be, the holders of Common
Stock shall be entitled to receive the remaining assets of the corporation pro
rata based upon the number of shares held by such holders of Common Stock.

          (d) For purposes of this Section 2, a merger or consolidation of the
Corporation with or into any other corporation or corporations, or the merger of
any other corporation or corporations into the Corporation, in which
consolidation or merger the shareholders of the Corporation receive
distributions in cash or securities of another corporation or corporations as a
result of such consolidation or merger, a sale of all or substantially all of
the assets of the Corporation, or the undertaking by the Corporation of a
transaction or series of transactions in which more than 50% of the voting power
of the Corporation is disposed of, shall be treated as a liquidation,
dissolution or winding up of the Corporation.

          (e) Any securities to be delivered to the holders of Preferred Stock
pursuant to Section 2(a) or 2(b) above shall be valued as follows:

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

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

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

                     (3) 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 Preferred Stock which would been entitled to receive such securities
or the same type of securities and which Preferred Stock represents at least a
majority of the voting power of all then outstanding shares of such Preferred
Stock.

                                      -3-
<PAGE>
 
              (ii)   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 subsections
2(e)(i)(1), (2) or (3) to reflect the approximate fair market value thereof, as
mutually determined by the Corporation and the holders of Preferred Stock which
would be entitled to receive such securities or the same type of securities and
which represent at least a majority of the voting power of all then outstanding
shares of such Preferred Stock.

          (f) In the event the requirements of Section 2(e) are not complied
with, the Corporation shall forthwith either:

              (i)    cause such closing to be postponed until such time as the
requirements of this Section 2 have been complied with, or

              (ii)   cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Preferred Stock shall revert to
and be the same as such rights, preferences and privileges existing immediately
prior to the date of the first notice referred to in Section 4(h) hereof.

          (g) As authorized by Section 402.5(c) of the California Corporations
Code, the provisions of Sections 502 and 503 of the California Corporations Code
shall not apply with respect to the repurchase by the corporation of shares of
Common Stock issued to or held by employees or consultants of the Corporation or
its subsidiaries upon termination of their employment or services pursuant to
any agreement providing for the right of said repurchase.

     3.   Voting Rights.
          ------------- 

          Holders of the Preferred Stock shall have full voting rights and
powers equal to the voting rights and powers of the holders of Common Stock, and
shall be entitled to vote, together with the holders of Common Stock, with
respect to any matters upon which holders of Common Stock have the right to
vote.  Except as otherwise required by law or by Section 6 hereof, the holder of
each share of Common Stock issued and outstanding shall have one vote and the
holder of each share of Preferred Stock shall be entitled to the number of votes
equal to the number of shares of Common Stock into which such share of Preferred
Stock could be converted 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.  Holders of Common
Stock and Preferred Stock shall be entitled to notice of any shareholders'
meeting in accordance with the Bylaws of the Corporation.

                                      -4-

     4.   Conversion.
          ---------- 

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

          (a) Right to Convert.  Each share 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.  Each share of Series A Preferred and Series B
Preferred shall be convertible into such number of fully paid and nonassessable
shares of Common Stock as is determined by dividing the Conversion Price (as
hereinafter defined) per share in effect for the Series A Preferred and Series B
Preferred into the per share Conversion Value (as hereinafter defined) of such
series.

          The Conversion Price per share of Series A Preferred shall be $1.5461
and the per share Conversion Value of Series A Preferred shall be $1.5461.  The
Conversion Price per share of Series B Preferred shall be $3.77 and the per
share Conversion Value of Series B Preferred shall be $3.77.  The Conversion
Price of Series A Preferred and Series B Preferred shall be subject to
adjustment from time to time as provided below.  The number of shares of Common
Stock to which a share of Series A Preferred or Series B Preferred is
convertible is hereinafter referred to as the Conversion Rate of such share.

          (b) Automatic Conversion.  Each share of Preferred Stock shall
              --------------------                                      
automatically be converted into shares of Common Stock at the then effective
Conversion Rate upon the closing of a firm commitment underwritten public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended, covering the offer and sale of Common Stock for the
account of the Corporation with an aggregate offering price to the public of not
less than $10,000,000.  In the event of the automatic conversion of the
Preferred Stock upon a public offering as aforesaid, the person(s) entitled to
receive the Common Stock issuable upon such conversion of Preferred Stock shall
not be deemed to have converted such Preferred Stock until immediately prior to
the closing of such sale of securities.

          (c) Mechanics of Conversion.  No fractional shares of Common Stock
              -----------------------                                       
shall be issued upon conversion of 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.  Before any holder of Preferred Stock shall be entitled to convert the
same into full shares of Common Stock and to receive certificates therefor, he
shall surrender the certificate or certificates therefor, duly endorsed, at the
office of the Corporation or of any transfer agent for the Preferred Stock, and
shall give written notice to the Corporation at such office that he elects to
convert the same; provided, however, that in the event of an automatic
conversion pursuant to Section 4(b), the outstanding shares of Preferred Stock
shall be converted automatically without any further action by the holders of
such shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its 

                                      -5-
<PAGE>
 
transfer agent, and provided further that the Corporation shall not be obligated
to issue certificates evidencing the shares of Common Stock issuable upon such
automatic conversion unless the certificates evidencing such shares of Preferred
Stock are either delivered to the Corporation or its transfer agent as provided
above, or the holder notifies the Corporation or its transfer agent that such
certificates have been lost, stolen or destroyed and executes an agreement
satisfactory to the Corporation to indemnify the Corporation from any loss
incurred by it in connection with such certificates. The Corporation shall, as
soon as practicable after such delivery, or such agreement and indemnification
in the case of a lost certificate, 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 he shall be entitled as aforesaid and a check
payable to the holder in the amount of any cash amounts payable as the result of
a conversion into fractional shares of Common Stock. Such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the shares of Preferred Stock to be converted, or in the
case of automatic conversion on the date of closing of the offering, 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 on such date.

          (d) Adjustments for Diluting Issues.
              ------------------------------- 

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

                     (1) "Options" shall mean rights, options or warrants to 
                          -------              
subscribe for, purchase or otherwise acquire either Common Stock or Convertible
Securities.

                     (2) "Original Issue Date" with respect to Series A 
                          -------------------       
Preferred means the date on which the first shares of such series were first
issued, and with respect to Series B Preferred means the date on which the first
shares of such series were first issued.

                     (3) "Convertible Securities" shall mean securities (other 
                          --------------------
than the Common Stock) convertible into or exchangeable for Common Stock.

                     (4) "Additional Shares of Common Stock" shall mean all 
                          ---------------------------------     
shares of Common Stock and Convertible Securities issued by the Corporation
after the Original Issue Date, other than shares of Common Stock and Convertible
Securities issued or issuable at any time:

                         (A) upon conversion of the shares of Series A Preferred
or Series B Preferred authorized herein or upon conversion of Convertible
Securities, provided that such Convertible Securities shall be deemed to be
Additional Shares of Common Stock;

                         (B) shares of Common Stock issued to employees,
officers, directors, consultants, contractors or advisors of the Corporation
pursuant to stock purchase or stock option plans or agreements or other
incentive stock arrangements approved by the Board of Directors;

                         (C) as a dividend or distribution on the Series A
Preferred or Series B Preferred or any event for which adjustment is made
pursuant to subparagraph (d)(iv) and (d)(vi) hereof;

                                      -6-
<PAGE>
 
                         (D) pursuant to any exercise of the Warrant to purchase
additional shares of Preferred Stock dated December 1996 made by the corporation
in favor of Synopsys, Inc.;

                         (E) in connection with capital asset leases or
borrowings for the acquisition of capital assets pursuant to approval by a
majority of the Board of Directors; or

                         (F) by way of a transaction described in Sections
4(d)(iv) through 4(d)(vi) below.

              (ii)   Adjustment of Conversion Price Upon Issuance of Additional
                     ----------------------------------------------------------
Shares of Common Stock.  In the event this Corporation shall issue Additional
- ----------------------                                                       
Shares of Common Stock after the Original Issue Date without consideration or
for a consideration per share less than the Conversion Price of any series of
Preferred Stock in effect on the date of and immediately prior to such issue,
then in such event, the Conversion Price for such series of Preferred Stock
shall be reduced, concurrently with such issue, to a price determined by
multiplying such Conversion Price by a fraction, 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 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; and provided further that, for the purposes of this Section 4(d)(ii),
all shares of Common Stock issuable upon conversion of outstanding Preferred
Stock or outstanding Options shall be deemed to be outstanding.

              (iii)  Determination of Consideration.  For purposes of this
                     ------------------------------                       
Section 4(d), the consideration received by the Corporation for the issue 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 received by the Corporation excluding amounts paid or
payable for accrued interest or accrued dividends;

                         (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; 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, be the proportion of such
consideration so received, computed as provided in clauses (A) and (B) above, as
determined in good faith by the Board.

<PAGE>
 
                     (2) Options and Convertible Securities. In the case of 
                         ----------------------------------                 
issuance of options to purchase or rights to subscribe for Common Stock, or
securities by their terms convertible into or exchangeable for Common Stock, the
following provisions shall apply for all purposes of Section 4(d):

                         (A) The aggregate maximum number of shares of Common
Stock deliverable upon exercise of such options to purchase or rights to
subscribe for Common Stock shall be deemed to have been issued at the time such
options or rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subparagraph 4(d)(iii)(1)), if any,
received by the Corporation upon the issuance of such options or rights plus the
exercise price provided in such options or rights for the Common Stock covered
thereby.

                         (B) The aggregate maximum number of shares of Common
Stock deliverable upon conversion or in exchange for such convertible or
exchangeable securities or upon the exercise of options to purchase or rights to
subscribe for such convertible or exchangeable securities and subsequent
conversion or exchange thereof shall be deemed to have been issued at the time
such securities were issued or such options or rights were issued and for a
consideration equal to the consideration, if any, received by the Corporation
for any such securities and related options or rights (excluding any cash
received on account of accrued interest or accrued dividends), plus the
additional consideration, if any, to be received by the corporation upon the
conversion or exchange of such securities or the exercise of any related options
or rights (the consideration in each case to be determined in the manner
provided in subparagraph 4(d)(iii)(1)).

                         (C) In the event of any change in the number of shares
of Common Stock deliverable or in the consideration payable to this corporation
upon exercise of such options or rights or upon conversion of or in exchange for
such convertible or exchangeable securities, including, but not limited to, a
change resulting from the antidilution provisions thereof, the Conversion Price
of the series of Preferred Stock, to the extent in any way affected by or
computed using such options, rights or securities, shall be recomputed to
reflect such change, but no further adjustment shall be made for the actual
issuance of Common Stock or any payment of such consideration upon the exercise
of any such options or rights or the conversion or exchange of such securities.

                         (D) Upon the expiration of any such options or rights,
the termination of any such rights to convert or exchange or the expiration of
any options or rights related to such convertible or exchangeable securities,
the Conversion Price of the series of Preferred Stock, to the extent in any way
affected by or computed using such options, rights or securities, shall be
recomputed to reflect the issuance of only the number of shares of Common Stock
(and convertible or exchangeable securities which remain in effect) actually
issued upon the conversion or exchange of such securities or upon the exercise
of the options or rights related to such securities.

                         (E) The number of shares of Common Stock deemed issued
and the consideration deemed paid therefor pursuant to subparagraphs
4(d)(iii)(2)(A) and (B) shall be appropriately adjusted to reflect any change,

              (iv)   Adjustments for Subdivisions, Combinations or Stock
                     ---------------------------------------------------
Dividends of Common Stock.  In the event the outstanding shares of Common Stock
- -------------------------                                                      
shall be subdivided (by stock split, or otherwise), into a greater number of
shares of Common Stock, or the Corporation at any time or from time to time
after the Original Issue Date shall declare or pay any dividend on the Common
Stock payable in Common Stock, the Conversion Price then in effect shall,
concurrently with the effectiveness of such subdivision or stock dividend, be
proportionately decreased based on the ratio of (i) the number of shares of
Common Stock outstanding immediately after such subdivision or stock dividend to
(ii) the number of shares of Common Stock outstanding immediately prior to such
subdivision or stock dividend.  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 then in effect
shall, concurrently with the effectiveness of such combination or consolidation,
be proportionately increased on the same basis.

              (v)    Adjustments for Other Distributions.  In the event the 
                     -----------------------------------        
Corporation at any time or from time to time makes, or fixes a record date for
the determination of holders of Common Stock entitled to receive any
distribution payable in (i) securities of the Corporation or other entities
(other than shares of Common Stock and other than as otherwise adjusted in this
Section 4), or (ii) evidences of indebtedness issued by the Corporation or other
persons, or (iii) assets (excluding cash dividends) or options or rights not
referred to in subparagraph 4(d)(iii)(2), then and in each such event provision
shall be made so that the holders of Preferred Stock shall receive upon
conversion thereof, in addition to the number of shares of Common Stock
receivable thereupon, the amount of such distribution which they would have
received had their Preferred Stock been converted into Common Stock on the date
of such event and had they thereafter, during the period from the date of such
event to and including the date of conversion, retained such securities
receivable by them as aforesaid during such period, subject to all other
adjustments called for during such period under this Section 4 with respect to
the rights of the holders of Preferred Stock.

              (vi)   Adjustments for Recapitalization, Reclassification, 
                     ---------------------------------------------------
Exchange and Substitution.  If at any time or from time to time the Common 
- -------------------------    
Stock issuable upon conversion of the Preferred Stock shall be changed into the
same or a different number of shares of any other class or classes of stock,
whether by recapitalization, capital reorganization, reclassification or
otherwise (other than a subdivision, combination of shares or merger or sale of
assets transaction provided for above or in Section 2(d)), the Conversion Rate
then in effect shall, concurrently with the effectiveness of such
recapitalization, reorganization or reclassification, be proportionately
adjusted such that the Preferred Stock shall be convertible into, in lieu of the
number of shares of Common Stock which the holders would otherwise have been
entitled to receive, a number of shares of such other class or classes of stock
equivalent to the number of shares of Common Stock that would have been subject
to receipt by the holders upon conversion of the Preferred Stock immediately
before that change. In addition, to the extent applicable in any reorganization
or recapitalization, provision shall be made so that the holders of the
Preferred Stock shall thereafter be entitled to receive upon conversion of the
Preferred Stock the number of shares of stock or other securities or property of
the Company or otherwise, to which a holder of Common Stock deliverable upon
conversion would have been entitled on such reorganization or recapitalization.

          (e) No Impairment.  Except as provided in Section 7, the Corporation
              -------------                                                   
will not, by amendment of its Restated Articles of Incorporation or 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 the holders of the Preferred Stock against impairment.

          (f) Certificate as to Adjustments.  Upon the occurrence of each
              -----------------------------                              
adjustment or readjustment of the Conversion Price or the Conversion Rate
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 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) such adjustments
and readjustments, (ii) the Conversion Price and the Conversion Rate 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 Preferred Stock.

          (g) Reservation of Stock Issuable Upon Conversion.   This 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
shares 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 the 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 the Preferred Stock, in addition to such other
remedies as shall be available to the holder of such Preferred Stock, this
corporation will take such corporate action as may, in the opinion of 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.

          (h) Notices of Record Date.  In the event that this Corporation shall
              ----------------------

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;

Common Stock outstanding involving a change in the Common Stock; or

holders of 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 and the amount and character of such dividend, distribution or
right) 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 when the same

shall be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event or the record date for
the determination of such holders if such record date is earlier).

the issue of shares of that series.

     The authority of the board of directors with respect to each such class or
series shall include, without limitation of the foregoing, the right to

terms;

               (c) the right or obligation, if any, of the corporation to redeem
shares of the particular class or series of Preferred Stock and, if redeemable,
the price, terms and manner of such redemption;

               (d) the special and relative rights and preferences, if any, and

     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.

                           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. In the absence of such
designation, the annual meeting of stockholders shall be held on the 14th day of
February 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.

           (b) At an annual meeting of the stockholders, only such business
shall be conducted as shall have been properly brought before the meeting. To be
properly brought before an annual meeting, business must be: (A) specified in
the notice of meeting (or any supplement thereto) given by or at the direction
of the Board of Directors, (B) otherwise properly brought before the meeting by
or 

                                      -1-
<PAGE>
 
at the direction of the Board of Directors, or (C) otherwise properly brought
before the meeting by a stockholder. For business to be properly brought before
an annual meeting by a stockholder, the stockholder must have given timely
notice thereof in writing to the Secretary of the corporation. To be timely, a
stockholder's notice must be delivered to or mailed and received at the
principal executive offices of the corporation not less than one hundred twenty
(120) calendar days in advance of the estimated mailing date for the proxy
statement relating to the corporation's next annual meeting as specified in the
corporation's proxy statement released to stockholders in connection with the
previous year's annual meeting of stockholders; provided, however, that in the
event that no annual meeting was held in the previous year or the date of the
annual meeting has been changed by more than thirty (30) days from the date
contemplated at the time of the previous year's proxy statement, notice by the
stockholder to be timely must be so received a reasonable time before the
solicitation is made. A stockholder's notice to the Secretary shall set forth as
to each matter the stockholder proposes to bring before the annual meeting: (i)
a brief description of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting, (ii)
the name and address, as they appear on the corporation's books, of the
stockholder proposing such business, (iii) the class and number of shares of the
corporation which are beneficially owned by the stockholder, (iv) any material
interest of the stockholder in such business and (v) any other information that
is required to be provided by the stockholder pursuant to Regulation 14A under
the Securities Exchange Act of 1934, as amended (the "1934 Act"), in his
capacity as a proponent to a stockholder proposal. Notwithstanding the
foregoing, in order to include information with respect to a stockholder
proposal in the proxy statement and form of proxy for a stockholder's meeting,
stockholders must provide notice as required by the regulations promulgated
under the 1934 Act. Notwithstanding anything in these Bylaws to the contrary, no
business shall be conducted at any annual meeting except in accordance with the
procedures set forth in this paragraph (b). The chairman of the annual meeting
shall, if the facts warrant, determine and declare at the meeting that business
was not properly brought before the meeting and in accordance with the
provisions of this paragraph (b), and, if he should so determine, he shall so
declare at the meeting that any such business not properly brought before the
meeting shall not be transacted.

           (c) Only persons who are nominated in accordance with the procedures
set forth in this paragraph (c) 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 in the
election of Directors at the meeting who complies with the notice procedures set
forth in this paragraph (c). 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 in accordance with the provisions
of paragraph (b) of this Section 2.2. Such stockholder's notice shall set forth
(i) as to each person, if any, whom the stockholder proposes to nominate for
election or re-election as a Director: (A) the name, age, business address and
residence address of such person, (B) the principal occupation or employment of
such person, (C) the class and number of shares of the corporation which are
beneficially owned by such person, (D) a description of all arrangements or
understandings between the stockholder and each nominee and any other person or
persons (naming such person or persons) pursuant to which the nominations are to
be made by the stockholder, and (E) any other information relating to such
person that is required to be disclosed in solicitations of proxies for
elections of Directors, or is otherwise required, in each case pursuant to
Regulation 14A under the 1934 Act (including without limitation such 

                                      -2-
<PAGE>
 
person's written consent to being named in the proxy statement, if any, as a
nominee and to serving as a Director if elected); and (ii) as to such
stockholder giving notice, the information required to be provided pursuant to
paragraph (b) of this Section 2.2. At the request of the Board of Directors, any
person nominated by a stockholder for election as a Director shall furnish to
the Secretary of the corporation that information required to be set forth in
the 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 paragraph (c). The chairman
of the meeting shall, if the facts warrants, determine and declare at the
meeting that a nomination was not made in accordance with the procedures
prescribed by these Bylaws, and if he should so determine, he shall so declare
at the meeting, and the defective nomination shall be disregarded.

     2.3   SPECIAL MEETING

     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 in the absence of the
chairman of the board by the chief executive officer, 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, but such special meetings may not be
called by any other person or persons.

     If a special meeting is called by any person or persons other than the
board of directors, 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, chief
executive officer, or the secretary of the corporation. No business may be
transacted at such special meeting otherwise than specified in such notice. The
officer receiving the request shall cause notice to be promptly given to the
stockholders entitled to vote, in accordance with the provisions of Sections 2.4
and 2.5, that a meeting will be held at the time requested by the person or
persons who called the meeting, 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 the receipt of the request, 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 stockholders called by action of the board of directors
may be held.

     2.4   NOTICE OF STOCKHOLDERS' MEETINGS

     Except as set forth in Section 2.3, all notices of meetings of stockholders
shall be sent or otherwise given in accordance with Section 2.5 of these bylaws
not less than ten (10) 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 stockholders (but 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.

                                      -3-
<PAGE>
 
     2.5   MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

     Written notice of any meeting of stockholders shall be given either
personally or by first-class mail or by telegraphic or other written
communication. Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the stockholder at the address of that stockholder
appearing on the books of the corporation or given by the 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 stockholder 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 stockholder at the address of that stockholder
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 stockholder 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 stockholder on written
demand of the stockholder 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
stockholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

     2.6   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 stockholders. The stockholders 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 stockholders 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 stockholders' 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 stockholders, 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 thirty (30) days from the date set for the original
meeting, then notice 

                                      -4-
<PAGE>
 
of the adjourned meeting shall be given. Notice of any such adjourned meeting
shall be given to each stockholder 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 stockholders entitled to vote at any meeting of stockholders shall be
determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation Law
of Delaware (relating to voting rights of fiduciaries, pledgors and joint
owners, and to voting trusts and other voting agreements).

     Except as may be otherwise provided in the Certificate of Incorporation,
each outstanding share, regardless of class, shall be entitled to one vote on
each matter submitted to a vote of the stockholders. Any stockholder 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
stockholder fails to specify the number of shares which the stockholder is
voting affirmatively, it will be conclusively presumed that the stockholder's
approving vote is with respect to all shares which the stockholder 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 stockholders, unless the vote of a greater number or a vote by classes is
required by law or by the Certificate of Incorporation.

     2.9   VALIDATION OF MEETINGS; WAIVER OF NOTICE; CONSENT

     The transactions of any meeting of stockholders, 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 stockholders. 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 law to be
included in the notice of the meeting but not so included, if that objection is
expressly made at the meeting.

     2.10  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

      Unless otherwise provided in the Certificate of Incorporation, any action
which may be taken at any annual or special meeting of stockholders 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.

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

     Following the closing date of the Company's initial public offering of 
shares of is Common Stock pursuant to an effective registration statement filed
with the Securities and Exchange Commission (the "IPO"), no action of
stockholders shall be taken by the stockholders except at an annual or special
meeting of the stockholders called in accordance with the notice requirements of
Section 2.5 above and no action of the stockholders shall be taken by written
consent.


     2.11  RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS

     For purposes of determining the stockholders 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 stockholders 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.

     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 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 stockholders 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, 

                                      -6-

shall be at the close of business on the day on which the board adopts the
resolution relating to that action.

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

     2.12  PROXIES

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

     2.13  INSPECTORS OF ELECTION

     Before any meeting of stockholders, 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 stockholder or a stockholder'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 stockholders 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 stockholder or
a stockholder'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;

           (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;

                                      -7-

           (f) determine the result; and

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

     3.1   POWERS

     Subject to the provisions of the General Corporation Law of Delaware and to
any limitations in the Certificate of Incorporation or these bylaws relating to

powers shall be exercised by or under the direction of the board of directors.

     3.2   NUMBER AND TERM OF OFFICE

certificate of incorporation.

     3.3   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

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 quorom, or by a sole remaining
director. Each director so elected shall hold office until the next annual
meeting of the stockholders and until a successor has been elected and
qualified.

     Unless otherwise provided in the Certificate of Incorporation or these
bylaws:

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

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

<PAGE>
 
     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.

entitled to vote at an election of directors; provided, however, that if and so
long as the stockholders of the corporation are entitled to cumulative voting,
if less than the entire board 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,
pursuant to Delaware General Corporation Law Section 141(k)(2).

     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.

                              RECORDS AND REPORTS
                              -------------------

    7.1    MAINTENANCE AND INSPECTION OF RECORDS

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

                                      -16-
<PAGE>
 
stockholder. The demand under oath shall be directed to the corporation at its
registered office in Delaware or at its principal place of business.

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

     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.

     7.4   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 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.

                                GENERAL MATTERS
                                ---------------

     8.1   RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

     For purposes of determining the stockholders entitled to receive payment of
any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any other lawful
action (other than action by stockholders 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
stockholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided by law.

     If the board of directors does not so fix a record date, then the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the board 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 confined to specific instances.
Unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

     8.4   STOCK CERTIFICATES; 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, 

                                      -18-
<PAGE>
 
or in the name of the corporation by, the chairman or vice-chairman of the board
of directors, or the president or vice-president, and by the chief financial
officer, 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.

     8.5   SPECIAL DESIGNATION ON CERTIFICATES

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

     8.6   LOST CERTIFICATES

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

    8.7    CONSTRUCTION; DEFINITIONS

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

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


                                   ARTICLE X

                                  DISSOLUTION
                                  -----------

     If it should be deemed advisable in the judgment of the board of directors
of the corporation that the corporation should be dissolved, the board, after
the adoption of a resolution to that effect by a majority of the whole board at
any meeting called for that purpose, shall cause notice to be mailed to each
stockholder entitled to vote thereon of the adoption of the resolution and of a
meeting of stockholders to take action upon the resolution.

     At the meeting a vote shall be taken for and against the proposed
dissolution. If a majority of the outstanding stock of the corporation entitled
to vote thereon votes for the proposed dissolution, then a certificate stating
that the dissolution has been authorized in accordance with the provisions of
Section 275 of the General Corporation Law of Delaware and setting forth the
names and residences of the directors and officers shall be executed,
acknowledged, and filed and shall become effective in accordance with Section
103 of the General Corporation Law of Delaware. Upon such certificate's becoming
effective in accordance with Section 103 of the General Corporation Law of
Delaware, the corporation shall be dissolved.

     Whenever all the stockholders entitled to vote on a dissolution consent in
writing, either in person or by duly authorized attorney, to a dissolution, no
meeting of directors or stockholders shall be necessary. The consent shall be
filed and shall become effective in accordance with Section 103 of the General
Corporation Law of Delaware. Upon such consent's becoming effective in
accordance with Section 103 of the General Corporation Law of Delaware, the
corporation shall be dissolved. If the consent is signed by an attorney, then
the original power of attorney or a photocopy thereof shall be 

                                      -20-
<PAGE>
 
attached to and filed with the consent. The consent filed with the Secretary of
State shall have attached to it the affidavit of the secretary or some other
officer of the corporation stating that the consent has been signed by or on
behalf of all the stockholders entitled to vote on a dissolution; in addition,
there shall be attached to the consent a certification by the secretary or some
other officer of the corporation setting forth the names and residences of the
directors and officers of the corporation.

                                   CUSTODIAN
                                   ---------

     11.1  APPOINTMENT OF A CUSTODIAN IN CERTAIN CASES

     The Court of Chancery, upon application of any stockholder, may appoint one
or more persons to be custodians and, if the corporation is insolvent, to be
receivers, of and for the corporation when:

           (i)   at any meeting held for the election of directors the
stockholders are so divided that they have failed to elect successors to
directors whose terms have expired or would have expired upon qualification of
their successors; or

           (ii)  the business of the corporation is suffering or is threatened
with irreparable injury because the directors are so divided respecting the
management of the affairs of the corporation that the required vote for action
by the board of directors cannot be obtained and the stockholders are unable to
terminate this division; or

          (iii)  the corporation has abandoned its business and has failed
within a reasonable time to take steps to dissolve, liquidate or distribute its
assets.

     11.2  DUTIES OF CUSTODIAN

     The custodian shall have all the powers and title of a receiver appointed
under Section 291 of the General Corporation Law of Delaware, but the authority
of the custodian shall be to continue the business of the corporation and not to
liquidate its affairs and distribute its assets, except when the Court of
Chancery otherwise orders and except in cases arising under Sections 226(a)(3)
or 352(a)(2) of the General Corporation Law of Delaware.

     1.   They are the President and Secretary, respectively, of Artisan

     2.   So much of Article III of the Restated Articles of Incorporation of
this corporation which currently reads as follows:

     of shares of Common Stock this corporation shall have authority to issue is
     25,000,000, and the total number of shares of Preferred Stock this

is hereby amended to read in its entirety as follows:

          "This corporation is authorized to issue two classes of shares to be

     of shares of Common Stock this corporation shall have authority to issue is
     50,000,000, and the total number of shares of Preferred Stock this

<PAGE>
 
     3.   Section 1, Article III of the Restated Articles of Incorporation of
this corporation shall be amended to read in its entirety as follows:

          "The holders of the Series A Preferred and Series B Preferred shall be
     entitled to receive, when and as declared by the Board of Directors,
     dividends out of funds legally available therefore, prior and in preference
     to any declaration or payment of any dividend (payable other than in Common
     Stock or other securities and rights convertible into or entitling the
     holder thereof to receive, directly or indirectly, additional shares of
     Common Stock of this Corporation) on the Common Stock of this Corporation,
     at the rate of $1.5461 and $3.77 per share, per annum, respectively.  Such
     dividends shall not be cumulative and no right to such dividends shall
     accrue to holders of Preferred Stock unless declared by the Board of
     Directors.  No dividends or other distributions shall be made with respect
     to the Common Stock, other than dividends payable solely in Common Stock,
     unless at the same time an equivalent dividend with respect to the
     Preferred Stock has been paid or set apart."

     4.   Section 2, Articles III(a) and (b) of the Restated Articles of
Incorporation of this corporation are hereby amended to read in their entirety
as follows:

          "(a)  In the event of a Liquidation before March 20, 1999, the holders
     of the 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 the Common Stock by reason of their ownership
     of such Preferred, an amount equal to the greater of (i) $1.5461 per share
     of Series A  Preferred or $3.77 per share of Series B Preferred,
     respectively (as adjusted for stock dividends, stock splits, stock
     combinations and the like, their respective "Original Purchase Price"),
     plus an amount equal to a 25% rate of return compounded annually on the
     Original Purchase Price from the date of issuance of the first share of
     Series A Preferred or Series B Preferred, respectively, issued to the date
     of Liquidation, plus all declared and unpaid dividends thereon to the date
     fixed for distribution of assets, or (ii) the amount of any such
     distribution as though the holders of the Series A Preferred or Series B
     Preferred, respectively, were the holders of that number of shares of
     Common Stock of the corporation into which their shares of Series A
     Preferred or Series B Preferred, respectively, are convertible as of the
     record date fixed for determination of the holders of Common Stock entitled
     to receive such distribution (in the aggregate, the "Liquidation Preference
     Amount"). If upon a Liquidation, the assets shall be insufficient to pay
     the holders of the Series A Preferred and Series B Preferred the full
     Liquidation Preference Amount, the holders of the Series A Preferred or
     Series B Preferred shall share ratably in any distribution of assets
     according to the respective amounts which would be payable in respect of
     the shares held by them upon such distribution if all amounts payable on or
     with respect to said shares were paid in full.

          (b)   In the event of a Liquidation occurring on or after March 20,
     1999, the holders of the 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 the Common Stock by reason of
     their ownership of such stock, an amount equal to the greater of (i)
     $1.5461 per share of each share of Series A Preferred or $3.77 per share of
     each share of Series B Preferred, respectively, then held by them (as
     adjusted for any stock dividends, stock splits,
<PAGE>
 
     recapitalizations, combinations, consolidations, or the like, with respect
     to shares of the Preferred Stock), plus an amount equal to any declared but
     unpaid dividends on the Preferred Stock, or (ii) the amount of any such
     distribution as though the holders of the Series A Preferred or Series B
     Preferred were the holders of that number of shares of Common Stock of the
     corporation into which their shares of Series A Preferred and Series B
     Preferred, respectively, are convertible as of the record date fixed for
     determination of the holders of Common Stock entitled to receive such
     distribution (the "Preference"). If upon a Liquidation, the assets shall be
     insufficient to pay the holders of the Series A Preferred and Series B
     Preferred the full Preference, the holders of the Series A Preferred or
     Series B Preferred shall share ratably in any distribution of assets
     according to the respective amounts which would be payable in respect of
     the shares held by them upon such distribution if all amounts payable on or
     with respect to said shares were paid in full."

     5.   So much of Section 4(a), Article III of the Restated Articles of
Incorporation of this corporation which currently reads as follows:

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

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

1.        Dividends.
          ----------

          The holders of the Series A Preferred and Series B Preferred shall be
entitled to receive, when and as declared by the Board of Directors, dividends
out of funds legally available therefore, prior and in preference to any
declaration or payment of any dividend (payable other than in Common Stock or

Corporation ("Liquidation"), either voluntary or involuntary, distributions to
the shareholders of the Corporation shall be made in the following manner:

     a.        In the event of a Liquidation before March 20, 1999, the holders
          of the 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 the Common Stock by reason of
          their ownership of such Preferred, an amount equal to the greater of
          (i) $1.5461 per share of Series A Preferred or $3.77 per share of

          or Series B Preferred, respectively, are convertible as of the record
          date fixed for determination of the holders of Common Stock entitled
          to receive such distribution (in the aggregate, the "Liquidation

          insufficient to pay the holders of the Series A Preferred and Series B
          Preferred the full Liquidation Preference Amount, the holders of the
          Series A Preferred or Series B Preferred shall share ratably in any
          distribution of assets according to the respective amounts which would

          1999, the holders of the 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 the Common Stock by
          reason of their ownership of such stock, an amount equal to the
          greater of (i) $1.5461 per share of each share of Series A Preferred
          or $3.77 per share of each share of Series B Preferred, respectively,
          then held by them (as adjusted for any stock dividends, stock splits,
          recapitalizations, combinations, consolidations, or the like, with
          respect to shares of the Preferred Stock), plus an amount equal to any
          declared but unpaid dividends on the Preferred Stock, or (ii) the
          amount of any such distribution as though the holders of the Series A
          Preferred or Series B Preferred were the holders of that number of
          shares of Common Stock of the corporation into which their shares of
          Series A Preferred and Series B Preferred, respectively, are
          convertible as of the record date fixed for determination of the
          holders of Common Stock entitled to receive such distribution (the
          "Preference"). If upon a Liquidation, the assets shall be insufficient
          to pay the holders of the Series A Preferred and Series B Preferred
          the full Preference, the holders of the Series A Preferred or
<PAGE>
 
          Series B Preferred shall share ratably in any distribution of assets
          according to the respective amounts which would be payable in respect
          of the shares held by them upon such distribution if all amounts
          payable on or with respect to said shares were paid in full.

     c.        After payment or setting apart of payment of the Liquidation
          Preference Amount or the Preference, as the case may be, the holders
          of Common Stock shall be entitled to receive the remaining assets of
          the corporation pro rata based upon the number of shares held by such
          holders of Common Stock.

     d.        For purposes of this Section 2, a merger or consolidation of the
          Corporation with or into any other corporation or corporations, or the
          merger of any other corporation or corporations into the Corporation,
          in which consolidation or merger the shareholders of the Corporation
          receive distributions in cash or securities of another corporation or
          corporations as a result of such consolidation or merger, a sale of
          all or substantially all of the assets of the Corporation, or the
          undertaking by the Corporation of a transaction or series of
          transactions in which more than 50% of the voting power of the
          Corporation is disposed of, shall be treated as a liquidation,
          dissolution or winding up of the Corporation.

     e.        Any securities to be delivered to the holders of Preferred Stock
          pursuant to Section 2(a) or 2(b) above shall be valued as follows:

          i.   Securities not subject to investment letter or other similar
               restrictions on free marketability:

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

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

               (3)       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 Preferred Stock which would
                    been entitled to receive such securities or the same type of
                    securities and which Preferred Stock represents at least a
                    majority of the voting power of all then outstanding shares
                    of such Preferred Stock.

          ii.  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 subsections 2(e)(i)(1), (2) or (3) to reflect the
               approximate fair market value thereof, as mutually determined by
               the Corporation and the
<PAGE>
 
               holders of Preferred Stock which would be entitled to receive
               such securities or the same type of securities and which
               represent at least a majority of the voting power of all then
               outstanding shares of such Preferred Stock.

     f.        In the event the requirements of Section 2(e) are not complied
          with, the Corporation shall forthwith either:

          (i)  cause such closing to be postponed until such time as the
               requirements of this Section 2 have been complied with, or

          (ii) cancel such transaction, in which event the rights, preferences
               and privileges of the holders of the Preferred Stock shall revert
               to and be the same as such rights, preferences and privileges
               existing immediately prior to the date of the first notice
               referred to in Section 4(h) hereof.

     g.        As authorized by Section 402.5(c) of the California Corporations
          Code, the provisions of Sections 502 and 503 of the California
          Corporations Code shall not apply with respect to the repurchase by
          the corporation of shares of Common Stock issued to or held by
          employees or consultants of the Corporation or its subsidiaries upon
          termination of their employment or services pursuant to any agreement
          providing for the right of said repurchase.

3.        Voting Rights.
          ------------- 

          Holders of the Preferred Stock shall have full voting rights and
powers equal to the voting rights and powers of the holders of Common Stock, and
shall be entitled to vote, together with the holders of Common Stock, with
respect to any matters upon which holders of Common Stock have the right to
vote.  Except as otherwise required by law or by Section 6 hereof, the holder of
each share of Common Stock issued and outstanding shall have one vote and the
holder of each share of Preferred Stock shall be entitled to the number of votes
equal to the number of shares of Common Stock into which such share of Preferred
Stock could be converted 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.  Holders of Common
Stock and Preferred Stock shall be entitled to notice of any shareholders'
meeting in accordance with the Bylaws of the Corporation.

4.        Conversion.
          ---------- 

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

     a.        Right to Convert.  Each share of Preferred Stock shall be
               ----------------                                      
     convertible, at the
<PAGE>
 
          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. Each share of Series A Preferred and Series B
          Preferred shall be convertible into such number of fully paid and
          nonassessable shares of Common Stock as is determined by dividing the
          Conversion Price (as hereinafter defined) per share in effect for the
          Series A Preferred and Series B Preferred into the per share
          Conversion Value (as hereinafter defined) of such series.

          The Conversion Price per share of Series A Preferred shall be $1.5461
and the per share Conversion Value of Series A Preferred shall be $1.5461.  The
Conversion Price per share of Series B Preferred shall be $3.77 and the per
share Conversion Value of Series B Preferred shall be $3.77.  The Conversion
Price of Series A Preferred and Series B Preferred shall be subject to
adjustment from time to time as provided below.  The number of shares of Common
Stock to which a share of Series A Preferred or Series B Preferred is
convertible is hereinafter referred to as the Conversion Rate of such share.

     b.        Automatic Conversion.  Each share of Preferred Stock shall
               --------------------                                      
          automatically be converted into shares of Common Stock at the then
          effective Conversion Rate upon the closing of a firm commitment
          underwritten public offering pursuant to an effective registration
          statement under the Securities Act of 1933, as amended, covering the
          offer and sale of Common Stock for the account of the Corporation with
          an aggregate offering price to the public of not less than
          $10,000,000.  In the event of the automatic conversion of the
          Preferred Stock upon a public offering as aforesaid, the person(s)
          entitled to receive the Common Stock issuable upon such conversion of
          Preferred Stock shall not be deemed to have converted such Preferred
          Stock until immediately prior to the closing of such sale of
          securities.

     c.        Mechanics of Conversion.  No fractional shares of Common Stock
               -----------------------
          shall be issued upon conversion of 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.  Before any holder of Preferred Stock
          shall be entitled to convert the same into full shares of Common Stock
          and to receive certificates therefor, he shall surrender the
          certificate or certificates therefor, duly endorsed, at the office of
          the Corporation or of any transfer agent for the Preferred Stock, and
          shall give written notice to the Corporation at such office that he
          elects to convert the same; provided, however, that in the event of an
          automatic conversion pursuant to Section 4(b), the outstanding shares
          of Preferred Stock shall be converted automatically without any
          further action by the holders of such shares and whether or not the
          certificates representing such shares are surrendered to the
          Corporation or its transfer agent, and provided further that the
          Corporation shall not be obligated to issue certificates evidencing
          the shares of Common Stock issuable upon such automatic conversion
          unless the certificates evidencing such shares of Preferred Stock are
          either delivered to the Corporation or its transfer agent as provided
          above, or the holder notifies the Corporation or its transfer agent
          that such certificates have been lost, stolen or destroyed and
          executes an agreement satisfactory to the Corporation to indemnify the
          Corporation from any
<PAGE>
 
          loss incurred by it in connection with such certificates. The
          Corporation shall, as soon as practicable after such delivery, or such
          agreement and indemnification in the case of a lost certificate, 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 he shall be entitled as aforesaid and a check payable to the
          holder in the amount of any cash amounts payable as the result of a
          conversion into fractional shares of Common Stock. Such conversion
          shall be deemed to have been made immediately prior to the close of
          business on the date of such surrender of the shares of Preferred
          Stock to be converted, or in the case of automatic conversion on the
          date of closing of the offering, 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 on such date.

     d.        Adjustments for Diluting Issues.
               ------------------------------- 

          (i). Special Definitions.  For purposes of this Section 4(d), the
               -------------------

                    series were first issued, and with respect to Series B
                    Preferred means the date on which the first shares of such

                 (a)     upon conversion of the shares of Series A Preferred or
                    Series B Preferred authorized herein or upon conversion of
                    Convertible Securities, provided that such Convertible

                      or Series B Preferred or any event for which adjustment is
                      made pursuant to subparagraph (d)(iv) and (d)(vi) hereof;

                 (e)     in connection with capital asset leases or borrowings

         (ii). Adjustment of Conversion Price Upon Issuance of Additional Shares
               -----------------------------------------------------------------
               of Common Stock.  In the event this Corporation shall issue
               ---------------                                            
               Additional Shares of Common Stock after the Original Issue Date
               without consideration or for a consideration per share less than
               the Conversion Price of any series of Preferred Stock in effect
               on the date of and immediately prior to such issue, then in such
               event, the Conversion Price for such series of Preferred Stock
               shall be reduced, concurrently with such issue, to a price
               determined by multiplying such Conversion Price by a fraction,
               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 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; and provided further that, for the purposes of
               this Section 4(d)(ii), all shares of Common Stock issuable upon
               conversion of outstanding Preferred Stock or outstanding Options
               shall be deemed to be outstanding.

        (iii). Determination of Consideration.  For purposes of this Section
               ------------------------------                               
               4(d), the consideration received by the Corporation for the issue
               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 received by the Corporation
                      excluding amounts paid or payable for accrued interest or
                      accrued dividends;

                 (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
<PAGE>
 
                      good faith by the Board; 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, be the proportion of such consideration so received,
                      computed as provided in clauses (A) and (B) above, as
                      determined in good faith by the Board.

               (2)       Options and Convertible Securities. In the case of
                      issuance of options to purchase or rights to subscribe for
                      Common Stock, or securities by their terms convertible
                      into or exchangeable for Common Stock, the following
                      provisions shall apply for all purposes of Section 4(d):

                 (a)     The aggregate maximum number of shares of Common Stock
                      deliverable upon exercise of such options to purchase or
                      rights to subscribe for Common Stock shall be deemed to
                      have been issued at the time such options or rights were
                      issued and for a consideration equal to the consideration
                      (determined in the manner provided in subparagraph
                      4(d)(iii)(1)), if any, received by the Corporation upon
                      the issuance of such options or rights plus the exercise
                      price provided in such options or rights for the Common
                      Stock covered thereby.

                 (b)     The aggregate maximum number of shares of Common Stock
                      deliverable upon conversion or in exchange for such
                      convertible or exchangeable securities or upon the
                      exercise of options to purchase or rights to subscribe for
                      such convertible or exchangeable securities and subsequent
                      conversion or exchange thereof shall be deemed to have
                      been issued at the time such securities were issued or
                      such options or rights were issued and for a consideration
                      equal to the consideration, if any, received by the
                      Corporation for any such securities and related options or
                      rights (excluding any cash received on account of accrued
                      interest or accrued dividends), plus the additional
                      consideration, if any, to be received by the corporation
                      upon the conversion or exchange of such securities or the
                      exercise of any related options or rights (the
                      consideration in each case to be determined in the manner
                      provided in subparagraph 4(d)(iii)(1)).

                 (c)     In the event of any change in the number of shares of
                      Common Stock deliverable or in the consideration payable
                      to this corporation upon exercise of such options or
                      rights or upon conversion of or in exchange for such
                      convertible or exchangeable securities, including, but not
                      limited to, a change resulting from the antidilution
                      provisions thereof, the Conversion Price of the series of
                      Preferred Stock, to the extent in any way affected by or
                      computed using such options, rights or securities, shall
                      be recomputed to reflect
<PAGE>
 
                      such change, but no further adjustment shall be made for
                      the actual issuance of Common Stock or any payment of such
                      consideration upon the exercise of any such options or
                      rights or the conversion or exchange of such securities.

                 (d)     Upon the expiration of any such options or rights, the
                      termination of any such rights to convert or exchange or
                      the expiration of any options or rights related to such
                      convertible or exchangeable securities, the Conversion
                      Price of the series of Preferred Stock, to the extent in
                      any way affected by or computed using such options, rights
                      or securities, shall be recomputed to reflect the issuance
                      of only the number of shares of Common Stock (and
                      convertible or exchangeable securities which remain in
                      effect) actually issued upon the conversion or exchange of
                      such securities or upon the exercise of the options or
                      rights related to such securities.

                 (e)     The number of shares of Common Stock deemed issued and
                      the consideration deemed paid therefor pursuant to
                      subparagraphs 4(d)(iii)(2)(A) and (B) shall be
                      appropriately adjusted to reflect any change, termination
                      or expiration of the type described in either subparagraph
                      4(d)(iii)(2)(C) or (D).

       (iv).   Adjustments for Subdivisions, Combinations or Stock Dividends of
               ----------------------------------------------------------------
               Common Stock.  In the event the outstanding shares of Common
               ------------                                                
               Stock shall be subdivided (by stock split, or otherwise), into a
               greater number of shares of Common Stock, or the Corporation at
               any time or from time to time after the Original Issue Date shall
               declare or pay any dividend on the Common Stock payable in Common
               Stock, the Conversion Price then in effect shall, concurrently
               with the effectiveness of such subdivision or stock dividend, be
               proportionately decreased based on the ratio of (i) the number of
               shares of Common Stock outstanding immediately after such
               subdivision or stock dividend to (ii) the number of shares of
               Common Stock outstanding immediately prior to such subdivision or
               stock dividend.  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 then in effect shall, concurrently with the
               effectiveness of such combination or consolidation, be
               proportionately increased on the same basis.

        (v).   Adjustments for Other Distributions.  In the event the
               -----------------------------------                   
               Corporation at any time or from time to time makes, or fixes a
               record date for the determination of holders of Common Stock
               entitled to receive any distribution payable in (i) securities of
               the Corporation or other entities (other than shares of Common
               Stock and other than as otherwise adjusted in this Section 4), or
               (ii) evidences of indebtedness issued by the Corporation or other
               persons, or (iii) assets (excluding cash dividends) or options or
               rights not referred to in subparagraph 4(d)(iii)(2), then and in
               each such event provision shall be made so that the holders of
               Preferred
<PAGE>
 
               Stock shall receive upon conversion thereof, in addition to the
               number of shares of Common Stock receivable thereupon, the amount
               of such distribution which they would have received had their
               Preferred Stock been converted into Common Stock on the date of
               such event and had they thereafter, during the period from the
               date of such event to and including the date of conversion,
               retained such securities receivable by them as aforesaid during
               such period, subject to all other adjustments called for during
               such period under this Section 4 with respect to the rights of
               the holders of Preferred Stock.

       (iv).   Adjustments for Recapitalization, Reclassification, Exchange and
               ----------------------------------------------------------------
               Substitution.  If at any time or from time to time the Common
               ------------                                                 
               Stock issuable upon conversion of the Preferred Stock shall be
               changed into the same or a different number of shares of any
               other class or classes of stock, whether by recapitalization,
               capital reorganization, reclassification or otherwise (other than
               a subdivision, combination of shares or merger or sale of assets
               transaction provided for above or in Section 2(d)), the
               Conversion Rate then in effect shall, concurrently with the
               effectiveness of such recapitalization, reorganization or
               reclassification, be proportionately adjusted such that the
               Preferred Stock shall be convertible into, in lieu of the number
               of shares of Common Stock which the holders would otherwise have
               been entitled to receive, a number of shares of such other class
               or classes of stock equivalent to the number of shares of Common
               Stock that would have been subject to receipt by the holders upon
               conversion of the Preferred Stock immediately before that change.
               In addition, to the extent applicable in any reorganization or
               recapitalization, provision shall be made so that the holders of
               the Preferred Stock shall thereafter be entitled to receive upon
               conversion of the Preferred Stock the number of shares of stock
               or other securities or property of the Company or otherwise, to
               which a holder of Common Stock deliverable upon conversion would
               have been entitled on such reorganization or recapitalization.

     e.        No Impairment.  Except as provided in Section 7, the Corporation
               -------------
          will not, by amendment of its Restated Articles of Incorporation or
          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 the holders of the Preferred Stock against impairment.

     f.        Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
          adjustment or readjustment of the Conversion Price or the Conversion
          Rate 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 Preferred Stock a
          certificate setting forth such adjustment or readjustment and
<PAGE>
 
          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) such adjustments and
          readjustments, (ii) the Conversion Price and the Conversion Rate 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 Preferred Stock.

     g.        Reservation of Stock Issuable Upon Conversion.   This 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 shares 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 the
          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 the Preferred Stock, in
          addition to such other remedies as shall be available to the holder of
          such Preferred Stock, this corporation will take such corporate action
          as may, in the opinion of 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.

     h.        Notices of Record Date.  In the event that this Corporation shall
               ----------------------                                           
          propose at any time:

               not a regular cash dividend and whether or not out of earnings or
               earned surplus;

       (ii).   to offer for subscription pro rata to the holders of any class or
               series of its stock any additional shares of stock of any class
               or series or other rights;

      (iii).   to effect any reclassification or recapitalization of its Common
               Stock outstanding involving a change in the Common Stock; or

       (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, this Corporation shall send to the
holders of Preferred Stock:

               (a)       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 and the amount and character of such dividend,
                    distribution or right) or for determining rights to vote in

                    date when the same 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 or the record
                    date for the determination of such holders if such record
                    date is earlier).

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

5.        Redemption.  The shares of Series A Preferred and Series B Preferred
          ----------
     shall not be redeemable.
     
6.        Voting Rights.
          ------------- 

     a.        Vote Other Than for Directors.  Except as otherwise required by
               -----------------------------   
          law, each share of Common Stock issued and outstanding shall have one
          vote and each share of Series A Preferred or Series B Preferred issued
          and outstanding shall have the number of votes equal to the number of
          shares of Common Stock into which the Series A Preferred or Series B
          Preferred is convertible as adjusted from time to time pursuant to
          Section 4 hereof.

     b.        Voting for Directors.  The Board of Directors shall consist of
               --------------------
          five (5) members. For so long as 25% or more of the issued shares of
          Series A Preferred have not been converted into Common Stock, the
          holders of the shares of Series A Preferred voting as a series shall
          be entitled to elect two (2) directors. The holders of Common Stock
          voting as a separate class shall be entitled to elect two (2)
          directors. The remaining director shall be elected by the holders of
          the Series A Preferred, Series B Preferred and Common Stock voting as
          provided in Section 6(a). In the event that 25% or more of the
          outstanding shares of Series A Preferred have been converted into

          holders of the Series A Preferred, Series B Preferred and Common Stock
          voting as provided in Section 6(a). A vacancy on the Board of
          Directors occurring because of the death, resignation or removal of a

          separate series shall be filled by the vote or written consent of the
          holders of a majority of the Series A Preferred. Any vacancy occurring
          because of the death, resignation or removal of a director elected by
          the holders of Common Stock voting as a separate class shall be filled
          by the vote or written consent of the holders of a majority of the
          Common Stock. Any vacancy occurring because of the death, resignation
          or removal of the director elected by the holders of the Series A
          Preferred, Series B Preferred and Common Stock voting together as a
          single class shall be filled by the vote or written consent of the
          holders of a majority of the Series A Preferred, Series B Preferred
          and Common Stock voting as provided in
<PAGE>
 
          Section 6(a). A director may be removed from the Board of Directors
          with or without cause by the vote or consent of the holders of the
          outstanding class or series with voting power entitled to elect him in
          accordance with this Section 6(b) and the California Corporations
          Code.

     c.        Cumulative Voting.  The holders of Common Stock, Series A
               -----------------  
          Preferred and Series B Preferred shall be entitled to cumulative
          voting rights as to the directors to be elected by each series or
          class, or the combined classes (as provided in Section 6(b) above), in
          accordance with the provisions of Section 708 of the California
          Corporations Code.

7.        Covenants.
          --------- 

          In addition to any other rights provided by law, so long as shares of
Series A Preferred and Series B Preferred shall be outstanding, this Corporation
shall not, without first obtaining the affirmative vote or written consent of
the holders of more than fifty percent (50%) of the outstanding shares of Series
A Preferred and Series B Preferred, voting together as a single class:

     a.        amend or repeal any provision of, or add any provision to, this
          Corporation's Restated Articles of Incorporation or Bylaws if such
          action would adversely alter or change the preferences, rights,
          privileges or powers of, or the restrictions provided for the benefit
          of the  Preferred Stock;

     b.        authorize or issue shares of any series or class of stock having
          any preference or priority as to dividends or assets superior to or on
          a parity with any such preference or priority of any series of
          Preferred Stock, or authorize shares of stock of any class or any
          bonds, debentures, notes or other obligations convertible into or
          exchangeable for, or having option rights to purchase, any shares of
          stock of this corporation having any preference or priority as to
          dividends or assets superior to or on a parity with any such
          preference or priority of the Preferred Stock;

     c.        effect in any transaction or series of transactions a sale or
          other conveyance of all or substantially all of the assets of the
          corporation or any of its subsidiaries, or any consolidation or merger
          involving the corporation or any of its subsidiaries where the
          corporation or such subsidiary is not the surviving corporation, or
          any sale of more than 50% of the corporation's capital stock; or

     d.        increase or decrease the authorized number of shares of Preferred
          Stock."

     3.   The foregoing Certificate of Amendment of Restated Articles of
Incorporation has been duly approved by the Board of Directors.

     4.   The foregoing Certificate of Amendment of Restated Articles of
Incorporation has been duly approved by the required vote of shareholders in
accordance with Section 902 and 903 of the California Corporations Code.  The
authorized number of shares of Common Stock is 15,000,000, of which 5,113,750
are issued and outstanding.  The authorized number of shares of
<PAGE>
 
Preferred Stock is 2,263,799, all of which have been designated Series A

                     RESTATED ARTICLES OF INCORPORATION OF

                          VLSI LIBRARIES INCORPORATED


     Mark R. Templeton and John G. Malecki certify that:

     1.   They are the President and Secretary of VLSI Libraries Incorporated, a
California corporation.

     2.   The Articles of Incorporation of this corporation are amended and
restated to read in full as follows:

                                      "I.

     The name of the corporation is VLSI Libraries Incorporated.

                                      II.

     The purpose of the corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
California other than the banking business, the trust company business or the
practice of a professional permitted to be incorporated by the California
Corporations Code.

                                     III.

     This corporation is authorized to issue two classes of shares to be
designated respectively Common Stock and Preferred Stock.  The total number of
shares of Common Stock this corporation shall have authority to issue is
15,000,000, and the total number of shares of Preferred Stock this corporation
shall have authority to issue is 2,263,799.  2,263,799 shares of Preferred Stock
shall be designated Series A Preferred Stock ("Series A Preferred").

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

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

     1.   Dividends.
          ----------

          The holders of the Series A Preferred shall be entitled to receive,
when and as declared by the Board of Directors, dividends out of funds legally
available therefore, prior and in preference to any declaration or payment of
any dividend (payable other than in Common Stock or other securities and rights
convertible into or entitling the holder thereof to receive, directly or
<PAGE>
 
indirectly, additional shares of Common Stock of this Corporation) on the Common
Stock of this Corporation, at the rate of $0.15461 per share, per annum.  Such
dividends shall not be cumulative and no right to such dividends shall accrue to
holders of Preferred Stock unless declared by the Board of Directors.  No
dividends or other distributions shall be made with respect to the Common Stock,
other than dividends payable solely in Common Stock, unless at the same time an
equivalent dividend with respect to the Preferred Stock has been paid or set
apart.

     2.   Liquidation Preference.
          ---------------------- 

          In the event of any liquidation, dissolution, or winding up of the
Corporation ("Liquidation"), either voluntary or involuntary, distributions to
the shareholders of the Corporation shall be made in the following manner:

          (a)  In the event of a Liquidation before March 20, 1999, the holders
of the Series A Preferred shall be entitled to receive, prior and in preference
to any distribution of any of the assets or surplus funds of the corporation to
the holders of the Common Stock by reason of their ownership of such Series A
Preferred, an amount equal to the greater of (i) $1.5461 per share of Series A
Preferred (as adjusted for stock dividends, stock splits, stock combinations and
the like, the "Original Purchase Price"), plus an amount equal to a 25% rate of
return compounded annually on the Original Purchase Price from the date of
issuance of the first share of Series A Preferred issued to the date of
liquidation, plus all declared and unpaid dividends thereon to the date fixed
for distribution of assets, or (ii) the amount of any such distribution as
though the holders of the Series A Preferred were the holders of that number of
shares of Common Stock of the corporation into which their shares of Series A
Preferred are convertible as of the record date fixed for determination of the
holders of Common Stock entitled to receive such distribution (in the aggregate,
the "Liquidation Preference Amount").  If upon a Liquidation, the assets shall
be insufficient to pay the holders of the Series A Preferred the full
Liquidation Preference Amount, the holders of the Series A Preferred shall share
ratably in any distribution of assets according to the respective amounts which
would be payable in respect of the shares held by them upon such distribution if
all amounts payable on or with respect to said shares were paid in full.

          (b)  In the event of a Liquidation occurring on or after March 20,
1999, the holders of the 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 the Common Stock by reason of their ownership of
such stock, an amount equal to the greater of (i) $1.5461 per share of each
share of Series A Preferred then held by them (as adjusted for any stock
dividends, stock splits, recapitalizations, combinations, consolidations, or the
like, with respect to shares of the Preferred Stock), plus an amount equal to
any declared but unpaid dividends on the Preferred Stock, or (ii) the amount of
any such distribution as though the holders of the Series A Preferred were the
holders of that number of shares of Common Stock of the corporation into which
their shares of Series A Preferred are convertible as of the record date fixed
for determination of the holders of Common Stock entitled to receive such
distribution (the "Preference"). If upon a Liquidation, the assets shall be
insufficient to pay the holders of the Series A Preferred the full Preference,
the holders of the Series A Preferred shall share ratably in any distribution of
assets according to the respective amounts which would be payable in respect of
the shares held by them upon such distribution if all amounts payable on or with
respect to said shares were paid in full.
<PAGE>
 
          (c)  After payment or setting apart of payment of the Preference, the
holders of Common Stock shall be entitled to receive the remaining assets of the
corporation pro rata based upon the number of shares held by such holders of
Common Stock.

          (d)  For purposes of this Section 2, a merger or consolidation of the
Corporation with or into any other corporation or corporations, or the merger of
any other corporation or corporations into the Corporation, in which
consolidation or merger the shareholders of the Corporation receive
distributions in cash or securities of another corporation or corporations as a
result of such consolidation or merger, a sale of all or substantially all of
the assets of the Corporation, or the undertaking by the Corporation of a
transaction or series of transactions in which more than 50% of the voting power
of the Corporation is disposed of, shall be treated as a liquidation,
dissolution or winding up of the Corporation.

          (e)  Any securities to be delivered to the holders of Preferred Stock
pursuant to Section 2(a) or 2(b) above shall be valued as follows:

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

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

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

               (3)       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 Preferred Stock which would been entitled to receive such securities
or the same type of securities and which Preferred Stock represents at least a
majority of the voting power of all then outstanding shares of such Preferred
Stock.

               (ii)      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 subsections
2(e)(i)(1), (2) or (3) to reflect the approximate fair market value thereof, as
mutually determined by the Corporation and the holders of Preferred Stock which
would be entitled to receive such securities or the same type of securities and
which represent at least a majority of the voting power of all then outstanding
shares of such Preferred Stock.

          (f)  In the event the requirements of Section 2(e) are not complied
with, the Corporation shall forthwith either:

               (i)       cause such closing to be postponed until such time as
the requirements of this Section 2 have been complied with, or
<PAGE>
 
               (ii)      cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Preferred Stock shall revert to
and be the same as such rights, preferences and privileges existing immediately
prior to the date of the first notice referred to in Section 4(h) hereof.

          (g)  As authorized by Section 402.5(c) of the California Corporations
Code, the provisions of Sections 502 and 503 of the California Corporations Code
shall not apply with respect to repurchase by the corporation of shares of
Common Stock issued to or held by employees or consultants of the Corporation or
its subsidiaries upon termination of their employment or services pursuant to
agreement providing for the right of said repurchase.

     3.   Voting Rights.
          ------------- 

          Holders of the Preferred Stock shall have full voting rights and
powers equal to the voting rights and powers of the holders of Common Stock, and
shall be entitled to vote, together with the holders of Common Stock, with
respect to any questions upon which holders of Common Stock have the right to
vote.  Except as otherwise required by law or by Section 6 hereof, the holder of
each share of Common Stock issued and outstanding shall have one vote and the
holder of each share of Preferred Stock shall be entitled to the number of votes
equal to the number of shares of Common Stock into which such share of Preferred
Stock could be converted 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.  Holders of Common
Stock and Preferred Stock shall be entitled to notice of any shareholders'
meeting in accordance with the Bylaws of the Corporation.

     4.   Conversion.
          ---------- 

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

          (a)  Right to Convert.  Each share 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.  Each share of Series A Preferred shall be convertible
into such number of fully paid and nonassessable shares of Common Stock as is
determined by dividing the Conversion Price (as hereinafter defined) per share
in effect for the Series A Preferred into the per share Conversion Value (as
hereinafter defined) of such series.

          The Conversion Price per share of Series A Preferred shall be $1.5461
and the per share Conversion Value of Series A Preferred shall be $1.5461. The
Conversion Price of Series A Preferred shall be subject to adjustment from time
to time as provided below.  The number of shares of Common Stock to which a
share of Series A Preferred is convertible is hereinafter referred to as the
Conversion Rate of such share.
<PAGE>
 
          (b)  Automatic Conversion.  Each share of Preferred Stock shall
               --------------------                                      
automatically be converted into shares of Common Stock at the then effective
Conversion Rate upon the closing of a firm commitment underwritten public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended, covering the offer and sale of Common Stock for the
account of the Corporation with an aggregate offering price to the public of not
less than $10,000,000.  In the event of the automatic conversion of the
Preferred Stock upon a public offering as aforesaid, the person(s) entitled to
receive the Common Stock issuable upon such conversion of Preferred Stock shall
not be deemed to have converted such Preferred Stock until immediately prior to
the closing of such sale of securities.

          (c)  Mechanics of Conversion.  No fractional shares of Common Stock
               -----------------------                                       
shall be issued upon conversion of 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.  Before any holder of Preferred Stock shall be entitled to convert the
same into full shares of Common Stock and to receive certificates therefor, he
shall surrender the certificate or certificates therefor, duly endorsed, at the
office of the Corporation or of any transfer agent for the Preferred Stock, and
shall give written notice to the Corporation at such office that he elects to
convert the same; provided, however, that in the event of an automatic
conversion pursuant to Section 4(b), the outstanding shares of Preferred Stock
shall be converted automatically without any further action by the holders of
such shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent, and provided further that
the Corporation shall not be obligated to issue certificates evidencing the
shares of Common Stock issuable upon such automatic conversion unless the
certificates evidencing such shares of Preferred Stock are either delivered to
the Corporation or its transfer agent as provided above, or the holder notifies
the Corporation or its transfer agent that such certificates have been lost,
stolen or destroyed and executes an agreement satisfactory to the Corporation to
indemnify the Corporation from any loss incurred by it in connection with such
certificates. The Corporation shall, as soon as practicable after such delivery,
or such agreement and indemnification in the case of a lost certificate, 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 he shall be
entitled as aforesaid and a check payable to the holder in the amount of any
cash amounts payable as the result of a conversion into fractional shares of
Common Stock.  Such conversion shall be deemed to have been made immediately
prior to the close of business on the date of such surrender of the shares of
Preferred Stock to be converted, or in the case of automatic conversion on the
date of closing of the offering, 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 on
such date.

          (d)  Adjustments for Diluting Issues.
               ------------------------------- 

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

               (1)  `Options' shall mean rights, options or warrants to
                     -------
subscribe for, purchase or otherwise acquire either Common Stock or Convertible
Securities.

               (2)  `Original Issue Date' with respect to Series A Preferred
                     -------------------
means the date
<PAGE>
 
on which the first shares of such series were first issued.

               (3)  `Convertible Securities' shall mean shares (other than the
                     ----------------------  
Common Stock) convertible into or exchangeable for Common Stock.

               (4)  `Additional Shares of Common Stock' shall mean all shares of
                     ---------------------------------
Common Stock and Convertible Securities issued by the Corporation after the
Original Issue Date, other than shares of Common Stock and Convertible
Securities issued or issuable at any time:

                    (A)  upon conversion of the shares of Series A Preferred
authorized herein or upon conversion of Convertible Securities, provided that
such Convertible Securities shall be deemed to be Additional Shares of Common
Stock;

                    (B)  up to 1,762,396 shares of Common Stock issued to
employees, officers, directors, consultants, contractors or advisors of the
Corporation pursuant to stock purchase or stock option plans or agreements or
other incentive stock arrangements approved by the Board of Directors;

                    (C)  as a dividend or distribution on Series A Preferred or
any event for which adjustment is made pursuant to subparagraph (d)(iv) and
(d)(vi) hereof;

                    (D)  in connection with capital asset leases or borrowings
for the acquisition of capital assets pursuant to approval by a majority of the
Board of Directors; or

                    (E)  by way of a transaction described in Sections 4(d)(iv)
through 4(d)(vi) below.

               (ii)  Adjustment of Conversion Price Upon Issuance of Additional
                     ----------------------------------------------------------
Shares of Common Stock. In the event this Corporation shall issue Additional
- ----------------------
Shares of Common Stock after the Original Issue Date without
consideration or for a consideration per share less than the Conversion Price of
any series of Preferred Stock in effect on the date of and immediately prior to
such issue, then in such event, the Conversion Price for such series of
Preferred Stock shall be reduced, concurrently with such issue, to a price
determined by multiplying such Conversion Price by a fraction, 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 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; and provided further that, for the
purposes of this Section 4(d)(ii), all shares of Common Stock issuable upon
conversion of outstanding Preferred Stock or outstanding Options shall be deemed
to be outstanding.

               (iii) Determination of Consideration.  For purposes of this
                     ------------------------------
Section 4(d), the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:
<PAGE>
 
               (1)   Cash and Property:  Such consideration shall:
                     -----------------                            

                     (A) insofar as it consists of cash, be computed at the
aggregate amount of cash received by the Corporation excluding amounts paid or
payable for accrued interest or accrued dividends;

                     (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; 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, be the proportion of such
consideration so received, computed as provided in clauses (A) and (B) above, as
determined in good faith by the Board.

               (2)   Options and Convertible Securities. In the case of issuance
                     ----------------------------------
of options to purchase or rights to subscribe for Common Stock, or securities by
their terms convertible into or exchangeable for Common Stock, the following
provisions shall apply for all purposes of Section 4(d):

                     (A) The aggregate maximum number of shares of Common Stock
deliverable upon exercise of such options to purchase or rights to subscribe for
Common Stock shall be deemed to have been issued at the time such options or
rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subparagraph 4(d)(iii)(1)), if any,
received by the Corporation upon the issuance of such options or rights plus the
exercise price provided in such options or rights for the Common Stock covered
thereby.

                     (B) The aggregate maximum number of shares of Common Stock
deliverable upon conversion or in exchange for such convertible or exchangeable
securities or upon the exercise of options to purchase or rights to subscribe
for such convertible or exchangeable securities and subsequent conversion or
exchange thereof shall be deemed to have been issued at the time such securities
were issued or such options or rights were issued and for a consideration equal
to the consideration, if any, received by the Corporation for any such
securities and related options or rights (excluding any cash received on account
of accrued interest or accrued dividends), plus the additional consideration, if
any, to be received by the corporation upon the conversion or exchange of such
securities or the exercise of any related options or rights (the consideration
in each case to be determined in the manner provided in subparagraph
4(d)(iii)(1)).

                     (C) In the event of any change in the number of shares of
Common Stock deliverable or in the consideration payable to this corporation
upon exercise of such options or rights or upon conversion of or in exchange for
such convertible or exchangeable securities, including, but not limited to, a
change resulting from the antidilution provisions thereof, the Conversion Price
of the series of Preferred Stock, to the extent in any way affected by or
computed using such options, rights or securities, shall be recomputed to
reflect such change, but no further adjustment shall be made for the actual
issuance of Common Stock or any payment of such consideration upon the exercise
of any such options or rights or the conversion or exchange of such securities.
<PAGE>
 
                     (D) Upon the expiration of any such options or rights, the
termination of any such rights to convert or exchange or the expiration of any
options or rights related to such convertible or exchangeable securities, the
Conversion Price of the series of Preferred Stock, to the extent in any way
affected by or computed using such options, rights or securities, shall be
recomputed to reflect the issuance of only the number of shares of Common Stock
(and convertible or exchangeable securities which remain in effect) actually
issued upon the conversion or exchange of such securities or upon the exercise
of the options or rights related to such securities.

                     (E) The number of shares of Common Stock deemed issued and
the consideration deemed paid therefor pursuant to subparagraphs 4(d)(iii)(2)(A)
and (B) shall be appropriately adjusted to reflect any change, termination or
expiration of the type described in either subparagraph 4(d)(iii)(2)(C) or (D).

               (iv)  Adjustments for Subdivisions, Combinations or Stock
                     ---------------------------------------------------
Dividends of Common Stock. In the event the outstanding shares of Common Stock
- -------------------------
shall be subdivided (by stock split, or otherwise), into a greater number of
shares of Common Stock, or the Corporation at any time or from time to time
after the Original Issue Date shall declare or pay any dividend on the Common
Stock payable in Common Stock, the Conversion Price then in effect shall,
concurrently with the effectiveness of such subdivision or stock dividend, be
proportionately decreased based on the ratio of (i) the number of shares of
Common Stock outstanding immediately after such subdivision or stock dividend to
(ii) the number of shares of Common Stock outstanding immediately prior to such
subdivision or stock dividend. 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 then in effect
shall, concurrently with the effectiveness of such combination or consolidation,
be proportionately increased on the same basis.

               (v)   Adjustments for Other Distributions.  In the event the
                     -----------------------------------   
Corporation at any time or from time to time makes, or fixes a record date for
the determination of holders of Common Stock entitled to receive any
distribution payable in (i) securities of the Corporation or other entities
(other than shares of Common Stock and other than as otherwise adjusted in this
Section 4 or as otherwise provided in Section 1(b)), or (ii) evidences of
indebtedness issued by the Corporation or other persons, or (iii) assets
(excluding cash dividends) or options or rights not referred to in subparagraph
4(d)(iii)(2), then and in each such event provision shall be made so that the
holders of Preferred Stock shall receive upon conversion thereof, in addition to
the number of shares of Common Stock receivable thereupon, the amount of such
distribution which they would have received had their Preferred Stock been
converted into Common Stock on the date of such event and had they thereafter,
during the period from the date of such event to and including the date of
conversion, retained such securities receivable by them as aforesaid during such
period, subject to all other adjustments called for during such period under
this Section 4 with respect to the rights of the holders of Preferred Stock.

               (vi)  Adjustments for Recapitalization, Reclassification,
                     ---------------------------------------------------
Exchange and Substitution. If at any time or from time to time the Common Stock
- -------------------------
issuable upon conversion of the Preferred Stock shall be changed into the same
or a different number of shares of any other class or classes of stock, whether
by recapitalization, capital reorganization, reclassification or otherwise
(other than a subdivision, combination of shares or merger or sale of assets
transaction provided for
<PAGE>
 
above or in Section 2(d)), the Conversion Rate then in effect shall,
concurrently with the effectiveness of such recapitalization, reorganization or
reclassification, be proportionately adjusted such that the Preferred Stock
shall be convertible into, in lieu of the number of shares of Common Stock which
the holders would otherwise have been entitled to receive, a number of shares of
such other class or classes of stock equivalent to the number of shares of
Common Stock that would have been subject to receipt by the holders upon
conversion of the Preferred Stock immediately before that change. In addition,
to the extent applicable in any reorganization or recapitalization, provision
shall be made so that the holders of the Preferred Stock shall thereafter be
entitled to receive upon conversion of the Preferred Stock the number of shares
of stock or other securities or property of the Company or otherwise, to which a
holder of Common Stock deliverable upon conversion would have been entitled on
such reorganization or recapitalization.

          (e)  No Impairment.  Except as provided in Section 7, the Corporation
               -------------                                                   
will not, by amendment of its Restated Articles of Incorporation or 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 the holders of the Preferred Stock against impairment.

          (f)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------                              
adjustment or readjustment of the Conversion Price or the Conversion Rate
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 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) such adjustments
and readjustments, (ii) the Conversion Price and the Conversion Rate 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 Preferred Stock.

          (g)  Reservation of Stock Issuable Upon Conversion.   This 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
shares 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 the 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 the Preferred Stock, in addition to such other
remedies as shall be available to the holder of such Preferred Stock, this
corporation will take such corporate action as may, in the opinion of 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.

          (h)  Notices of Record Date.  In the event that this Corporation shall
               ----------------------                                           
propose at any time:
<PAGE>
 
               (i)   to declare any dividend or distribution upon its 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;

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

               (iii) to effect any reclassification or recapitalization of its
Common Stock outstanding involving a change in the Common Stock; or

               (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, this Corporation shall send to the
holders of 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 and the amount and character of such dividend, distribution or right) or
for determining rights to vote in respect of the matters referred to in (iii)
and (iv) above; and

SECTION 9. VOTING

     Only shareholders of record on the record date fixed for voting purposes by
the board of directors pursuant to Article VIII, Section 3 of these bylaws, or,
if there be no such date fixed, on the record dates given below, shall be
entitled to vote at a meeting.

     If no record date is fixed:

     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.

     b.   The record date for determining the shareholders entitled to give
consent to corporate actions in writing without a meeting, when no prior action
by the board is necessary, shall be the day on which the first written consent
is given.

     c.   The record date for determining shareholders for any other purpose
shall be at the close of business on the day on which the board adopts the
resolution relating thereto, or the 60th day prior to the date of such other
action, whichever is later.

     Every shareholder entitled to vote shall be entitled to one vote for each
share held, except as otherwise provided by law, by the Articles of
Incorporation or by other provisions of these bylaws.  Except with respect to
elections of directors, any shareholder entitled to vote may vote part of his or
her shares in favor of a proposal and refrain from voting the remaining shares
or vote them against the proposal.  If a shareholder fails to specify the number
of shares he or she is affirmatively voting, it will be conclusively presumed
that the shareholder's approving vote is with respect to all shares the
shareholder is entitled to vote.

     At each election of directors, shareholders shall not be entitled to
cumulate votes unless the candidates' names have been placed in nomination
before the commencement of the voting and a shareholder has given notice at the
meeting, and before the voting has begun, of his or her intention to cumulate
votes.  If any shareholder has given such notice, then all shareholders entitled
to vote may cumulate their votes by giving one candidate a number of votes equal
to the number of directors to be elected multiplied by the number of his or her
shares or by distributing such votes on the same principle among any number of
candidates as he or she thinks fit.  The candidates receiving the highest number
of votes, up to the number of directors to be elected, shall be elected.  Votes
cast against a candidate or which are withheld shall have no effect.  Upon the
demand of any shareholder made before the voting begins, the election of
directors shall be by ballot rather by voice vote.


SECTION 10. PROXIES

     Every person entitled to vote shares may authorize another person or
persons to act by proxy with respect to such shares by filing a written proxy
with the secretary for the corporation, executed by such person or his or her
duly authorized agent.

the date thereof unless otherwise provided in the proxy.  Every proxy shall
continue in full force and effect until revoked by the person executing it prior
to the vote pursuant thereto, except as otherwise provided in Section 705 of the
California Corporations (Code.

under the direction of, the board of directors.

     The authorized number of directors shall be 5.

     After issuance of shares, this bylaw may only be amended by approval of a

bylaw reducing the fixed number of directors to a number less than five (5)
cannot be adopted unless in accordance with the additional requirements of
Article IX of these Bylaws.

SECTION 3. ELECTION AND TENURE OF OFFICE

     The directors shall be elected at the annual meeting of the shareholders
and hold office until the next annual meeting and until their successors have
been elected and qualified.

resignation, or removal of any director or in case the authorized number of
directors is increased, or in case the shareholders fail to elect the full
authorized number of directors at any annual or special meeting of the
shareholders at which any director is elected.  The board of directors may
declare vacant the office of a director who has been declared of unsound mind by
an order of court or who has been convicted of a felony.

     Except for the vacancy created by the removal of a director, vacancies on
the board of directors may be filled by approval of the board or, if the number
of directors then in the office is less than a quorum, by (1) the unanimous
written consent of directors then in office, (2) the affirmative vote of a
majority of the directors then in office at a meeting held pursuant to notice or
waivers of notice complying with this Article of these Bylaws, or (3) a sole
remaining director.  Vacancies occurring on the board by reason of the removal
of directors may be filled only by approval of the shareholders.  Each director
so elected shall hold office until the next annual meeting of the shareholders
and until his or her successor has been elected and qualified.

  -  The shareholders may elect a director at any time to fill a vacancy not
filled by the directors.  Any such election by written consent other than to
fill a vacancy created by the removal of a director requires the consent of a
majority of the outstanding shares entitled to vote.

     Any director may resign effective upon giving written notice to the
chairperson of the board of directors, the president, the secretary or to the
board of directors unless the notice specifies a later time for the
effectiveness of the resignation.  If the resignation is effective at a later
time, a successor may be elected to take office when the resignation becomes
effective.  Any reduction of the authorized number of directors does not remove
any director prior to the expiration of such director's term in office.

<PAGE>

SECTION 5. REMOVAL

     Any or all of the directors may be removed without cause if such removal is
approved by a majority of the outstanding shares entitled to vote, subject to
the provisions of Section 303 of the California Corporations Code.  Except as
provided in Sections 302, 202 and 304 of the California Corporations Code, a
director may not be removed prior to the expiration of such director's term of
office.

holding at least 10 percent of the number of outstanding shares of any class,
remove from office any director in case of fraudulent or dishonest acts of gross
abuse of authority or discretion with reference to the corporation and may bar
from re-election any director so removed for a period prescribed by the court.
The corporation shall be made a party to such action.

SECTION 6. PLACE OF MEETINGS

     Meetings of the board of directors shall be held at any place, within or
without the State of California, which has been designated in the notice of the
meeting or, if not stated in the notice or if there is no notice, at the
principal executive office of the corporation or as may be designated from time
to time by resolution of the board of directors.  Meetings of the board may be
held through use of conference telephone or similar communications equipment, as
long as all directors participating in the meeting can hear one another.

at a meeting duly held at which a quorum is present is the act of the board,
subject to the provisions of Section 310 (relating to the approval of contracts
and transactions in which a director has a material financial interest); the
provisions of Section 311 (designation of committees), and Section 317(e)
(indemnification of directors) of the California Corporations Code.  A meeting
at which a quorum is initially present may continue to transact business

at least a majority of the required quorum for such meeting.
 
<PAGE>

SECTION 9. WAIVER OF NOTICE

     The transactions of any meeting of the board, however called and noticed or
wherever held, are as valid as though undertaken at a meeting duly held after
regular call and notice if a quorum is present and if, either before or after
the meeting, each of the directors not present signs a written waiver of notice,
a consent to holding the meeting, or an approval of the minutes thereof.  All
such waivers, consents, and approvals shall be filed with the corporate records
or made a part of the minutes of the meeting.  Waivers of notice or consents
need not specify the purpose of the meeting.


SECTION 10. ACTION WITHOUT MEETING

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

SECTION 11. COMPENSATION

     No salary shall be paid directors, as such, for their services but, by
resolution. the board of directors may allow a reasonable fixed sum and expenses
to be paid for attendance at regular or special meetings.  Nothing contained

capacity and receiving compensation therefor.  Members of special or standing
committees may be allowed like compensation for attendance at meetings.

which prohibits or otherwise limits indemnification; or

                                  Article VII


Section 4 Restrictions on Transfer of Shares.  Before there can be a valid sale
          ----------------------------------
or transfer for consideration of any of the shares of Common Stock (other than
shares of Common Stock issued upon conversion of any Preferred Stock) of the
corporation by any holder thereof, he shall first offer those shares to the
corporation and then to the other holders of Common Stock in the following
manner:

          (a)  The offering shareholder shall deliver a notice in writing by
mail or otherwise to the secretary of the corporation stating the price, terms,
and conditions of such proposed sale or transfer, the number of shares to be
sold or transferred, and his intention so to sell or transfer the shares. Within
ten (10) days thereafter, the corporation shall have the prior right to purchase
all (but not less than all unless this requirement is waived by the seller) of
the shares offered at the price and upon the terms and conditions stated in such
notice. Should the corporation fail to purchase all of said shares but shall
determine that the other shareholders should have the opportunity to purchase
said shares, then, at the expiration of said ten (10) day period or prior
thereto upon the determination of the corporation to purchase none of such
shares so offered, the secretary of the corporation shall, within two (2) days
thereafter, mail or deliver to each of the other shareholders a notice
setting forth the particulars concerning the shares not purchased by the
corporation described in the notice received from the offering shareholder. The
other shareholders shall have the right to purchase all (but not less than all
unless this requirement is waived by the seller) of the shares specified in the
secretary's notice. Each shareholder shall deliver to the secretary by mail or
otherwise a written offer or offers to purchase all or any specified number of
shares upon the terms described in the secretary's notice within eighteen (18)
days after the secretary's notice was mailed or delivered to the other
shareholders. If the total number of shares specified in such offers received
within such period by the secretary exceeds the number of shares referred to in
the secretary's notice, then each offering shareholder shall be entitled to
purchase such portion of the shares referred to in the secretary's notice as the
number of shares of Common Stock (and shares of Common Stock issuable upon
conversion of Preferred Stock) which he holds bears to the total number of
shares of Common Stock (and shares of Common Stock issuable upon conversion of
Preferred Stock) held by all shareholders desiring to purchase the shares
referred to in the secretary's notice.

          (b) If all of the shares referred to in the secretary's notice are not
disposed of under such apportionment, then each shareholder desiring to purchase
shares in a number in excess of his proportionate share, as provided above,
shall be entitled to purchase such proportion of those shares which remain thus
indisposed of as the total number of shares of Common Stock (and shares of
Common Stock issuable upon conversion of Preferred Stock) which he holds bears
to the total number of shares of Common Stock (and shares of Common Stock
issuable upon conversion of Preferred Stock) held by all of the shareholders
desiring to purchase shares in excess of those to which they are entitled under
such apportionment Such apportionment shall be made successively until all of
the shares offered have been allocated to purchasing shareholders.
 
<PAGE>

          (c)  If none or only a part of the shares in the offering
shareholder's notice to the secretary is purchased by the corporation or by
other shareholders within a thirty (30) day period from the date of delivery of
the notice by the offering shareholder the offering shareholder may sell or
transfer to any person or persons all shares of stock referred to in his notice
to the secretary that were not purchased by the corporation or by the other
shareholders, but only within a period of one hundred twenty (120) days from the
date of his first notice; provided, however, that he shall not sell or transfer
such shares at a lower price or on terms more favorable to the purchaser or
transferee than those specified in his notice to the secretary. After said 120-
day period, the foregoing procedure for first offering shares to the corporation
and shareholders shall again apply.

          (d)  Within the limitations herein provided, the corporation may
purchase the shares of this corporation from any offering shareholder; provided,
however, that at no time shall the corporation be permitted to purchase all of
its outstanding voting shares.  Any sale or transfer or purported sale or
transfer of the shares of the corporation shall be null and void unless the
terms, conditions, and provisions of this Section 4 are strictly observed and
followed.

          (e)  The corporation shall place an appropriate legend on all
certificates for its shares referring to the provisions of this Section 4
restricting the transfer of shares.

          (f)  Notwithstanding the foregoing, the implementation of this Section
4 shall occur only after compliance with or waiver of the Right of First Refusal
set forth in Section 3 of the Right of First Refusal and Co-Sale Agreement dated
March 20, 1996.

          (g)  The provisions of this Section 4 shall terminate and be of not
further force or effect upon the effective date of the corporation's first
registration of shares of its capital stock with the Securities and Exchange
Commission.

                                  Article III


Section 7 ANNUAL, REGULAR AND SPECIAL DIRECTOR'S MEETINGS

          An annual meeting of the board of directors shall be held without
notice immediately after and at the same place as the annual meeting of the
shareholders.

          Other regular meetings of the board of directors shall be held at such
times and places as may be fixed from time to time by board of directors.  Call
and notice of these regular meetings shall not required.

          Special meetings of the board of directors may be called by the
chairperson of the board, the president, the vice president, secretary, or any
two directors.  Special meetings of the board of directors shall be held upon
four (4) days' notice by mail, or forty-eight (48) hours' notice delivered
personally or by telephone or telegraph.  A notice or waiver of notice need not
specify the purpose of any special meeting of the board of directors.

          Notwithstanding the foregoing, however, in the event that the officers
of the corporation have received an indication of interest from an unaffiliated
third party with respect to a material transaction with the corporation,
including but not limited to (i) a merger or acquisition of the corporation in
which the corporation would not be the surviving entity, (ii) an offer to invest
in the corporation or (iii) an agreement not to consider other proposals from
other parties during the pendency of discussions with the third party requesting
such a "no shop" agreement, the officers will consider whether the proposal from
the third party is credible enough to warrant the calling of a special board
meeting to consider such indication of interest.  In no event will the officers
enter into any such agreements without calling such a special meeting and
obtaining board approval therefor.  If such a meeting of the board of directors
is called, notice of such meeting, together with a written agenda describing the
matter(s) to be considered, must be circulated at least five (5) calendar days
prior to the date of such meeting to all members of the board of directors and
to any holders of board observation rights.  The special notice provisions of
this paragraph shall terminate and be of no further force or effect upon the
earlier of (i) the effective date of the corporation's first registration of
shares of its capital stock with the Securities and Exchange Commission or (ii)
the closing of an acquisition or merger of the corporation in which the
corporation is not the surviving entity.

          If any meeting is adjourned for more than 24 hours, notice of the
adjournment to another time or place shall be given before the time of the
resumed meeting to all directors who were not present at the time of adjournment
of the original meeting.

     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.
     SUCH SHARES MAY NOT BE SOLD, TRANSFERRED OR PLEDGED IN THE ABSENCE OF SUCH
     REGISTRATION OR UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL (WHICH
     MAY BE COUNSEL FOR THE COMPANY) REASONABLY ACCEPTABLE TO IT STATING THAT
     SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS
     DELIVERY REQUIREMENTS OF SAID ACT."

     "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."

     Each Purchaser and Holder consents to the Company making a notation on its
records and giving instructions to any transfer agent of the Restricted
Securities in order to implement the restrictions on transfer established in
this Section 1.

     1.4  Notice of Proposed Transfers.  The holder of each certificate
          ----------------------------                                 
representing Restricted Securities, by acceptance thereof, agrees to comply in
all respects with the provisions of this Section 1. Prior to any proposed sale,
assignment, transfer or pledge of any Restricted Securities, unless there is in
effect a registration statement under the Securities Act covering the proposed
transfer, the holder thereof shall give written notice to the Company of such
holder's intention to effect such transfer, sale, assignment or pledge.  Each
such notice shall describe the manner and circumstances of the proposed
transfer, sale, assignment or pledge in sufficient detail, and shall be
accompanied at such holder's expense by either (i) an unqualified written
opinion of legal counsel who shall, and whose legal opinion shall be, reasonably
satisfactory to the Company, addressed to the Company, to the effect that the
proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act, or (ii) a "no action" letter from the
Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be 

                                      -3-
<PAGE>
 
taken with respect thereto, whereupon the holder of such Restricted Securities
shall be entitled to transfer such Restricted Securities in accordance with the
terms of the notice delivered by the holder to the Company. The Company will not
require such a legal opinion or "no action" letter (a) in any transaction in
compliance with Rule 144, (b) in any transaction in which a Purchaser which is a
corporation distributes Restricted Securities after six (6) months after the
purchase thereof solely to its majority-owned subsidiaries or affiliates for no
consideration, or (c) in any transaction in which a Purchaser which is a
partnership distributes Restricted Securities after six (6) months after the
purchase thereof solely to partners thereof for no consideration, provided that
each transferee agrees in writing to be subject to the terms of this Section
1.4. Each certificate evidencing the Restricted Securities transferred as above
provided shall bear, except if such transfer is made pursuant to Rule 144, the
appropriate restrictive legend set forth in Section 1.3 above, except that such
certificate shall not bear such restrictive legend if, in the opinion of counsel
for such holder and the Company, such legend is not required in order to
establish compliance with any provisions of the Securities Act.

      1.5 Requested Registration.
          ---------------------- 

          (a) Request for Registration.  In case the Company shall receive from
              ------------------------                                         
Initiating Holders a written request that the Company effect any qualification,
compliance or registration (which, in connection with the Company's initial
public offering, must reasonably anticipate an  aggregate price to the public
net of underwriting discounts and commissions, exceeding $10,000,000), the
Company will:

              (i)   promptly give written notice of the proposed registration,
qualification or compliance to all other Holders; and

              (ii)  as soon as practicable, use its best efforts to effect such
registration, qualification or compliance (including, without limitation, the
execution of an undertaking to file post-effective amendments, appropriate
qualification under applicable blue sky or other state securities laws and
appropriate compliance with applicable regulations issued under the Securities
Act and any other governmental requirements or regulations) as may be so
requested and as would permit or facilitate the sale and distribution of all or
such portion of such Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or
Holders joining in such request as are specified in a written request received
by the Company within twenty (20) days after receipt of such written notice from
the Company; provided, however, that the Company shall not be obligated to take
             --------                                                          
any action to effect any such registration, qualification or compliance pursuant
to this Section 1.5:

                    (1) In any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                    (2) Prior to the earlier of (i) six (6) months following the
Company's initial public offering or (ii) January 1, 2001.

                                      -4-
<PAGE>
 
                    (3) During the period ending on the date three (3) months
immediately following the effective date of, any registration statement
pertaining to securities of the Company (other than a registration of securities
in a Rule 145 transaction or with respect to an employee benefit plan);

                    (4) After the Company has effected two (2) such
registrations pursuant to this subparagraph 1.5(a), such registrations have been
declared or ordered effective and the securities offered pursuant to such
registrations have been sold; or

                    (5) If the Company shall furnish to such Holders a
certificate, signed by the President of the Company, stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company or its shareholders for a registration statement to be filed in the
near future, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 1. 5 shall be deferred for a single period
not to exceed one hundred-twenty (120) days from the date of receipt of written
request from the Initiating Holders.

     Subject to the foregoing clauses (1) through (5), the Company shall file a
registration statement covering the Registrable Securities so requested to be
registered as soon as practicable after receipt of the request or requests of
the Initiating Holders.

          (b) Underwriting.  In the event that a registration pursuant to
              ------------                                               
Section 1.5 is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the notice given pursuant to
Section 1.5(a)(i). The right of any Holder to registration pursuant to Section
1.5 shall be conditioned upon such Holder's participation in the underwriting
arrangements required by this Section 1.5 and the inclusion of such Holder's
Registrable Securities in the underwriting, to the extent requested, to the
extent provided in this Agreement.

     The Company shall (together with all Holders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form with the managing underwriter selected for such underwriting by a
majority in interest of the Initiating Holders (which managing underwriter shall
be reasonably acceptable to the Company).  Notwithstanding any other provision
of this Section 1.5, if the managing underwriter advises the Initiating Holders
in writing that marketing factors require a limitation of the number of shares
to be underwritten, then the Company shall so advise all Holders of Registrable
Securities and the number of shares of Registrable Securities that may be
included in the registration and underwriting shall be allocated among all
Holders thereof in proportion, as nearly as practicable, to the respective
amounts of Registrable Securities held by such Holders at the time of filing the
registration statement.  No Registrable Securities excluded from the
underwriting by reason of the underwriter's marketing limitation shall be
included in such registration.  To facilitate the allocation of shares in
accordance with the above provisions, the Company or the underwriters may round
the number of shares allocated to any Holder to the nearest 100 shares.

     If any Holder of Registrable Securities disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, the managing underwriter and the Initiating Holders.  The
Registrable Securities and/or other securities so withdrawn shall also be

                                      -5-
<PAGE>
 
withdrawn from registration, and such Registrable Securities shall not be
transferred in a public distribution prior to one hundred eighty (180) days
after the effective date of such registration.

      1.6 Company Registration.
          -------------------- 

          (a) Notice of Registration.  If at any time or from time to time, the
              ----------------------                                           
Company shall determine to register any of its securities, either for its own
account or the account of a security holder or holders other than (i) a
registration relating solely to employee benefit plans, or

(ii) a registration relating solely to a Commission Rule 145 transaction, the
Company will:

              (i)   promptly give to each Holder written notice thereof; and

              (ii)  include in such registration (and any related qualification
under  blue sky laws or other compliance), and in any underwriting involved in
such registration, all the Registrable Securities specified in a written request
or requests made within twenty (20) days after receipt of such written notice
from the Company by any Holder, but only to the extent that such inclusion will
not diminish the number of securities included by the Company or by holders of
the Company's securities who have demanded such registration.

          (b) Underwriting.  If the registration of which the Company gives
              ------------                                                 
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 1.6(a)(i). In such event, the right of any Holder to
registration pursuant to Section 1.6 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company (or by the
holders who have demanded such registration).  Notwithstanding any other
provision of this Section 1.6, if the managing underwriter determines that
marketing factors require a limitation of the number of shares to be
underwritten, the managing underwriter may limit the Registrable Securities to
be included in such registration to a minimum of 30% of the total shares to be
included in such underwriting or exclude them entirely in the case of the
Company's initial public offering.  The Company shall so advise all Holders and
the other holders distributing their securities through such underwriting
pursuant to piggyback registration rights similar to this Section 1.6, and the
number of shares of Registrable Securities and other securities that may be
included in the registration and underwriting shall be first allocated among all
Purchasers in proportion, as nearly as practicable, to the respective amounts of
Registrable Securities held by such Purchasers at the time of filing the
registration statement, and after satisfaction of the requirements of the
Purchasers, the remaining shares that may be included in the registration and
underwriting shall be allocated among the officers, directors and other
shareholders of the Company in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities held by such officers and directors
of the Company at the time of filing of the registration statement.  To
facilitate the allocation of shares in accordance with the above provisions, the
Company or the underwriters may round the number of shares allocated to any
Holder or other holder to the nearest 100 shares.  If any Holder or other holder
disapproves of the terms 

                                      -6-
<PAGE>
 
of any such underwriting, he or she may elect to withdraw therefrom by written
notice to the Company and the managing underwriter. Any securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration, and
shall not be transferred in a public distribution prior to one hundred eighty
(180) days after the effective date of the registration statement relating
thereto (the "Lock-Up Period"); provided, however, that if such registration is
not the Company's initial public offering such Lock-Up Period shall be one
hundred twenty (120) days unless the managing underwriter determines that
marketing factors require a longer period in which case the Lock-Up period shall
be specified by the managing underwriter but shall not exceed one hundred eighty
(180) days.

          (c) Right to Terminate Registration.  The Company shall have the right
              -------------------------------                                   
to terminate or withdraw any registration initiated by it under this Section 1.6
prior to the effectiveness of such registration, whether or not any Holder has
elected to include securities in such registration.

      1.7 Registration on Form S-3.
          ------------------------ 

          (a) If the Initiating Holder requests that the Company file a
registration statement on Form S-3 (or any successor form to Form S-3) for a
public offering of shares of the Registrable Securities, the reasonably
anticipated aggregate price to the public of which, net of underwriting
discounts and commissions, would exceed $500,000, and the Company is a
registrant entitled to use Form S-3 to register the Registrable Securities for
such an offering, the Company shall use its best efforts to cause such
Registrable Securities to be registered for the offering on such form; provided,
                                                                       -------- 
however, that the Company shall not be required to effect more than one
- -------                                                                
registration pursuant to this Section 1.7 in any twelve (12) month period.  The
Company will (i) promptly give written notice of the proposed registration to
all other Holders, and (ii) as soon as practicable, use its best efforts to
effect such registration (including, without limitation, the execution of an
undertaking to file post-effective amendments, appropriate qualification under
applicable blue sky or other state securities laws and appropriate compliance
with applicable regulations issued under the Securities Act and any other
governmental requirements or regulations) as may be so requested and as would
permit or facilitate the sale and distribution of all or such portion of such
Registrable Securities as are specified in such request, together with all or
such portion of the Registrable Securities of any Holder or Holders joining in
such request as are specified in a written request received by the Company
within twenty (20) days after receipt of such written notice from the Company.
The substantive provisions of Section 1.5(b) shall be applicable to each
registration initiated under this Section 1.7.

          (b) Notwithstanding the foregoing, the Company shall not be obligated
to take any action pursuant to this Section 1.7: (i) in any particular
jurisdiction in which the Company would be required to execute a general consent
to service of process in effecting such registration, qualification or
compliance unless the Company is already subject to service in such jurisdiction
and except as may be required by the Securities Act, (ii) during the period
ending on a date three (3) months following the effective date of, a
registration statement (other than with respect to a registration statement
relating to a Rule 145 transaction, an offering solely to employees or any other
registration which is not appropriate for the registration of Registrable
Securities), or (iii) if the Company shall furnish to such Holder a certificate
signed by the President of the Company stating that, in the good faith judgment
of the Board of Directors, it would be seriously detrimental to the Company or
its shareholders for registration 

                                      -7-
<PAGE>
 
statements to be filed in the near future, then the Company's obligation to use
its best efforts to file a registration statement shall be deferred for a single
period not to exceed one hundred twenty (120) days from the receipt of the
request to file such registration by such Holder or Holders.

      1.8  Limitations on Subsequent Registration Rights.  From and after the
           ---------------------------------------------                     
date of this Agreement, the Company shall not enter into any agreement granting
any holder or prospective holder of any securities of the Company registration
rights with respect to such securities unless such holder derives its rights as
an additional Holder hereunder, or such shares or securities are entitled to be
included in registrations only to the extent that the inclusion of such
securities will not diminish the amount of Registrable Securities that are
included.

      1.9  Expenses of Registration.  All Registration Expenses incurred in
           ------------------------                                        
connection with any registration pursuant to Sections 1.5, 1.6 or 1.7 and the
reasonable cost of one special legal counsel to represent all of the Holders
together in any such registration shall be borne by the Company, provided that
the Company shall not be required to pay the Registration Expenses of any
registration proceeding begun pursuant to Section 1.5, the request of which has
been subsequently withdrawn by the Initiating Holders.  In such case, the
Holders of Registrable Securities to have been registered shall bear all such
Registration Expenses pro rata on the basis of the number of shares to have been
registered unless the Holders of a majority of the Registrable Securities agree
to forfeit their right to one demand registration pursuant to Section 1.5.
Notwithstanding the foregoing, however, if at the time of the withdrawal, the
Holders have learned of a material adverse change in the condition, business or
prospects of the Company from that known to the Holders at the time of their
request, of which the Company had knowledge at the time of the request, then the
Holders shall not be required to pay any of said Registration Expenses or to
forfeit the right to one demand registration.

      1.10 Registration Procedures.  In the case of each registration,
           -----------------------                                    
qualification or compliance effected by the Company pursuant to this Section 1,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof.  At its expense the Company will:

           (a) Prepare and file with the Commission a registration statement
with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least one hundred
eighty (180) days or until the distribution described in the registration
statement has been completed; and

           (b) Furnish to the Holders participating in such registration and to
the underwriters of the securities being registered such reasonable number of
copies of the registration statement, preliminary prospectus, final prospectus
and such other documents as such underwriters may reasonably request in order to
facilitate the public offering of such securities.

      1.11 Indemnification.
           --------------- 

           (a) The Company will indemnify each Holder, each of its officers and
directors and partners, and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, 

                                     -8-
<PAGE>
 
with respect to which registration, qualification or compliance has been
effected pursuant to this Section 1, and each underwriter, if any, and each
person who controls any underwriter within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages or liabilities (or
actions in respect thereof), including any of the foregoing incurred in
settlement of any litigation, commenced or threatened, arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any registration statement, prospectus, offering circular or other
document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading, or any violation by the Company of any rule or
regulation promulgated under the Securities Act applicable to the Company in
connection with any such registration, qualification or compliance, and the
Company will reimburse each such Holder, each of its officers and directors, and
each person controlling such Holder, each such underwriter and each person who
controls any such underwriter, for any legal and any other expenses reasonably
incurred in connection with investigating, preparing or defending any such
claim, loss, damage, liability or action, provided that the Company will not be
liable in any such case to the extent that any such claim, loss, damage,
liability or expense arises out of or is based on any untrue statement or
omission or alleged untrue statement or omission, made in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder, controlling person or underwriter and stated to be
specifically for use therein.

          (b) Each Holder will, if Registrable Securities held by such Holder
are included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, each of its directors and
officers, each underwriter, if any, of the Company's securities covered by such
a registration statement, each person who controls the Company or such
underwriter within the meaning of Section 15 of the Securities Act, and each
other such Holder, each of its officers and directors and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company, such Holders, such directors, officers, persons, underwriters or
control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder and
stated to be specifically for use therein; provided, however, that the liability
of a Holder for indemnification under this Section 1.11(b) shall not exceed the
gross proceeds from the offering received by such Holder.

          (c) Each party entitled to indemnification under this Section 1.11
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may 

                                     -9-
<PAGE>
 
be sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section I unless the failure to
give such notice is materially prejudicial to an Indemnifying Party's ability to
defend such action. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

      1.12 Information by Holder.  The Holder or Holders of Registrable
           ---------------------                                       
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders, the Registrable Securities held by
them and the distribution proposed by such Holder or Holders as the Company may
request in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Section 1.

      1.13 Rule 144 Reporting.  With a view to making available the benefits of
           ------------------                                                  
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Securities to the public without registration, after such
time as a public market exists for the Common Stock of the Company, the Company
agrees to use its best efforts to:

           (a) Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times after
the effective date that the Company becomes subject to the reporting
requirements of the Securities Act or the Securities Exchange Act of 1934, as
amended (the "Exchange Act");

           (b) File with the Commission in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act
(at any time after it has become subject to such reporting requirements); and

           (c) So long as a Purchaser owns any Restricted Securities, furnish to
the Purchaser forthwith upon request a written statement by the Company as to
its compliance with the reporting requirements of said Rule 144 (at any time
after ninety (90) days after the effective date of the first registration
statement filed by the Company for an offering of its securities to the general
public), and of the Securities Act and the Exchange Act (at any time after it
has become subject to such reporting requirements), a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents
of the Company and other information in the possession of or reasonably
obtainable by the Company as a Purchaser may reasonably request in availing
itself of any rule or regulation of the Commission allowing a Purchaser to sell
any such securities without registration.

      1.14 Transfer of Registration Rights.  The rights to cause the Company to
           -------------------------------                                     
register securities granted Purchasers under Sections 1.5, 1.6 and 1.7 may be
assigned to a transferee or assignee 

                                     -10-
<PAGE>
 
reasonably acceptable to the Company in connection with any transfer or
assignment of Registrable Securities by a Purchaser (together with any
affiliate); provided, that (a) such transfer may otherwise be effected in
            --------
accordance with applicable securities laws, (b) notice of such assignment is
given to the Company, and (c) such transferee or assignee (i) is a wholly-owned
subsidiary or constituent partner (including limited partners) of such
Purchaser, or (ii) acquires from such Purchaser 20% or more of the shares of
Registrable Securities (as appropriately adjusted for stock splits and the like)
originally purchased by the Purchaser from the Company.

      1.15 Standoff Agreement. Each Holder agrees in connection with the initial
           ------------------
registration of the Company's securities that, upon request of the Company or
the underwriters managing any underwritten initial public offering of the
Company's securities, not to sell, make any short sale of, loan, grant any
option for the purchase of, or otherwise dispose of any Registrable Securities
(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 one hundred eighty (180) days from the effective date of
such registration) as may be requested by the Company or such managing
underwriters; provided, however, that the officers and directors of the Company
who own stock of the Company also agree to such restrictions.

      1.16 Termination of Rights.  No Holder shall be entitled to exercise any
           ---------------------                                              
right provided for in this Section 1:

           (a) after five (5) years following the consummation of the sale of
securities pursuant to a registration statement filed by the Company under the
Act in connection with the initial firm commitment underwritten offering of its
securities to the general public, or

           (b) on or after the closing of a public offering of the Common Stock
of the Company, initiated by the Company, when all shares of the Holder's
Registrable Securities may be sold under Rule 144 during any 90-day period;
provided, however, that the provisions of this subsection (b) shall not apply
where the Holder owns more than two percent (2%) of the Company's outstanding
stock until such time as such Holder owns less than two percent (2%) of the
outstanding stock.

                                   SECTION 2

                            Right of Participation
                            ----------------------

      2.1  Purchasers' Right of Participation.
           ---------------------------------- 

           (a)  Right of Participation.
                ---------------------- 

                (i)  Subject to the terms and conditions contained in this
Section 2. 1, the Company hereby grants to each Purchaser the right of
participation to purchase its Pro Rata Portion of any New Securities (as defined
in subsection 2.1 (b)) which the Company may, from time to time, propose to sell
and issue. A Holder's "Pro Rata Portion" for purposes of this Section 2.1 is the
ratio that (x) the sum of the number of shares of the Company's Common Stock
then held by such Purchaser and 

                                     -11-
<PAGE>
 
the number of shares of the Company's Common Stock issuable upon conversion of
the Preferred Stock then held by such Holder, bears to (y) the sum of the total
number of shares of the Company's Common Stock then outstanding, the number of
shares of the Company's Common Stock issuable upon the exercise of any
outstanding rights, options or warrants, and the number of shares of the
Company's Common Stock issuable upon conversion of the then outstanding
Preferred Stock.

                (ii) Notwithstanding the foregoing, Synopsys' Pro Rata Portion
for purposes of this Section 2.1 is the ratio that (x) the sum of the number of
shares of the Company's Common Stock then held by Synopsys and the number of
shares of the Company's Common Stock issuable upon conversion of the Preferred
Stock then held by Synopsys and the number of shares of the Company's Common
Stock which would be issuable upon conversion of Preferred Stock then
purchasable by Synopsys assuming that Synopsys has exercised its Warrant to the
full extent then exercisable, bears to (y) the sum of the total number of shares
of the Company's Common Stock then outstanding and the number of shares of the
Company's Common Stock issuable upon conversion of the then outstanding
Preferred Stock.

          (b)   Definition of New Securities.  Except as set forth below, "New
                ----------------------------                                  
Securities" shall mean any shares of capital stock of the Company, including
Common Stock and Preferred Stock, whether authorized or not, and rights, options
or warrants to purchase said shares of Common Stock or Preferred Stock, and
securities of any type whatsoever that are, or may become, convertible into said
shares of Common Stock or Preferred Stock.  Notwithstanding the foregoing, "New
Securities" does not include (i) the Preferred Shares or the Conversion Shares,
(ii) securities offered to the public generally pursuant to a registration
statement under the Securities Act; provided, however, that this exclusion will
not apply to Synopsys solely with respect to the first sale by the Company of
its Common Stock to the public pursuant to a registration statement under the
Securities Act, (iii) securities issued pursuant to the acquisition of another
corporation by the Company by merger, purchase of substantially all of the
assets or shares or other reorganization whereby the Company or its shareholders
own not less than a majority of the voting power of the surviving or successor
corporation, (iv) up to 1,762,396 shares of the Company's Common Stock or
related options or warrants convertible into or exercisable for such Common
Stock issued to employees, officers and directors of, and consultants to, the
Company, pursuant to any arrangement approved by the Board of Directors of the
Company, (v) shares of the Company's Common Stock or related options convertible
into or exercisable for such Common Stock issued to banks, commercial lenders,
lessors and other financial institutions in connection with the borrowing of
money or the leasing of equipment by the Company, (vi) stock issued pursuant to
any rights or agreements, including, without limitation, convertible securities,
options and warrants, provided that the Company shall have complied with the
rights of participation established by this Section 2.1 with respect to the
initial sale or grant by the Company of such rights or agreements, (vii) stock
issued in connection with any stock split, stock dividend or recapitalization by
the Company, or (viii) any securities issued to Synopsys pursuant to any
exercise of the Warrant.

          (c)   Notice of Right.  In the event the Company proposes to undertake
                ---------------                                                 
an issuance of New Securities, it shall give each Purchaser written notice of
its intention, describing the type of New Securities and the price and terms
upon which the Company proposes to issue the same.  Each Purchaser shall have
twenty (20) days from the date of receipt of any such notice to agree to
purchase shares of 

                                     -12-
<PAGE>
 
such New Securities (up to the amount referred to in subsection 2.1 (a)), for
the price and upon the terms specified in the notice, by giving written notice
to the Company and stating therein the quantity of New Securities to be
purchased. In the event Synopsys exercises its right to purchase New Securities
in connection with the first offering made to the public generally pursuant to a
registration statement under the Securities Act, the price paid by Synopsys for
such New Securities shall be the public offering price less any underwriting
discounts and commissions.

          (d)   Exercise of Right.  If any Purchaser exercises its right of
                -----------------                                          
participation under this Agreement, the closing of the purchase of the New
Securities with respect to which such right has been exercised shall take place
within ninety (90) calendar days after the Purchaser gives notice of such
exercise, which period of time shall be extended in order to comply with
applicable laws and regulations. Upon exercise of such right of participation,
the Company and the Purchaser shall be legally obligated to consummate the
purchase contemplated thereby and shall use their best efforts to secure any
approvals required in connection therewith.

          (e)   Lapse and Reinstatement of Right. In the event a Purchaser fails
                --------------------------------
to exercise the right of participation provided in this Section 2.1 within said
twenty (20) day period, the Company shall have ninety (90) days thereafter to
sell or enter into an agreement (pursuant to which the sale of New Securities
covered thereby shall be closed, if at all, within sixty (60) days from the date
of said agreement) to sell the New Securities not elected to be purchased by
such Purchaser at the price and upon terms no more favorable to the purchasers
of such securities than specified in the Company's notice. In the event the
Company has not sold the New Securities or entered into an agreement to sell the
New Securities within said ninety (90) day period (or sold and issued New
Securities in accordance with the foregoing within sixty (60) days from the date
of said agreement), the Company shall not thereafter issue or sell any New
Securities without first offering such securities to the Purchasers in the
manner provided above.

          (f)   Assignment.  The right of the Purchasers to purchase any part of
                ----------                                                      
the New Securities may be assigned in whole or in part to any partner,
subsidiary, affiliate or shareholder of a Purchaser, or other persons or
organizations who acquire the lesser of (i) 20% or more shares of Restricted
Securities (as adjusted for stock splits and the like) or (ii) all of the
Restricted Securities then owned by such Purchaser.

      2.2 Termination of Participation Right.  The rights of participation
          ----------------------------------                              
granted under Section 2.1 of this Agreement shall terminate on and be of no
further force or effect upon the earlier of (i) the consummation of the
Company's sale of its Common Stock in an underwritten public offering pursuant
to an effective registration statement filed under the Securities Act
immediately subsequent to which the Company shall be obligated to file annual
and quarterly reports with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act or (ii) the registration by the Company of a class of its equity
securities under Section 12(b) or 12(g) of the Exchange Act.

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

      3.1  Assignment. Except as otherwise provided in this Agreement, the terms
           ----------
and conditions of this Agreement shall inure to the benefit of and be binding
upon the respective successors and assigns of the parties to this Agreement.

      3.2  Third Parties.  Nothing in this Agreement, express or implied, is
           -------------                                                    
intended to confer upon any party, other than the parties to this Agreement, and
their respective successors and assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement.

      3.3  Governing Law.  This Agreement shall be governed by and construed
           -------------                                                    
under the laws of the State of California in the United States of America
without giving effect to the conflicts of laws principles thereof.

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

      3.5  Notices.  Any notice required or permitted by this Agreement shall be
           -------                                                              
in writing and shall be sent by prepaid registered or certified mail return
receipt requested, or otherwise delivered by hand or by messenger addressed to
the other party at the address shown below or at such other address for which
such party gives notice under this Agreement.  Such notice shall be deemed to
have been given when delivered if delivered personally, or, if sent by mail, at
the earlier of its receipt or three (3) days after deposit in the mail.

      3.6  Severability. If one or more provisions of this Agreement are held to
           ------------   
be unenforceable under applicable law, portions of such provisions, or such
provisions in their entirety, to the extent necessary, shall be severed from
this Agreement, and the balance of this Agreement shall be enforceable in
accordance with its terms.

      3.7  Amendment and Waiver.  Any provision of this Agreement may be amended
           --------------------                                                 
or waived with the written consent of the Company and the Holders of at least a
majority of the outstanding shares of the Registrable Securities, so long as the
effect is to treat all Holders equally.  Any amendment or waiver effected in
accordance with this paragraph shall be binding upon each Holder of Registrable
Securities and the Company.  In addition, the Company may waive performance of
any obligation owing to it, as to some or all of the Holders of Registrable
Securities, or agree to accept alternatives to such performance, without
obtaining the consent of any Holder of Registrable Securities.  In the event
that an underwriting agreement is entered into between the Company and any
Holder, and such underwriting agreement contains terms differing from this
Agreement, as to any such Holder the terms of such underwriting agreement shall
govern.

      3.8  Effect of Amendment or Waiver.  The Purchasers and their successors
           -----------------------------                                      
and assigns acknowledge that by the operation of Section 3.7 of this Agreement
the holders of a majority of the outstanding Registrable Securities, acting in
conjunction with the Company, will have the right and power to diminish or
eliminate any or all rights or increase any or all obligations pursuant to this
Agreement.

      3.9  Rights of Holders.  Each holder of Registrable Securities shall have
           -----------------                                                   
the absolute right to exercise or refrain from exercising any right or rights
that such holder may have by reason of this Agreement, including, without
limitation the right to consent to the waiver or modification of any obligation
under this Agreement, and such holder shall not incur any liability to any other
holder of any securities of the Company as a result of exercising or refraining
from exercising any such right or rights.

      3.10 Delays or Omissions.  No delay or omission to exercise any right,
           -------------------                                              
power or remedy accruing to any party to this Agreement, upon any breach or
default of the other party, shall impair any such right, power or remedy of such
non-breaching party nor shall it be construed to be a waiver of any such breach
or default, or an acquiescence therein, or of or in any similar breach or
default thereafter occurring; nor shall any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or
thereafter occurring.  Any waiver, permit, consent or approval of any kind or
character on the part of any party of any breach or default under this
Agreement, or any waiver on the part of any party of any provisions or
conditions of this Agreement, must be made in writing and shall be effective
only to the extent specifically set forth in such writing.  All remedies, either
under this Agreement, or by law or otherwise afforded to any holder, shall be

           ------------------------------                                 
Purchasers are parties to a Registration Rights Agreement dated March 20, 1996
(the "Prior Agreement").  Through their execution of this Agreement, the Company
and all of the Purchasers agree to terminate the Prior Agreement and restate the
terms thereof through this Agreement, with the result that this Agreement shall
constitute the sole agreement among the parties hereto with respect to the
registration of Registrable Securities.

     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933 (THE "SECURITIES ACT"), AS AMENDED, AND MAY NOT BE
     SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN
     EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN
     OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION
     IS NOT REQUIRED.

     THE WARRANT REPRESENTED BY THIS CERTIFICATE IS ISSUED PURSUANT TO AND IS
     SUBJECT TO A SERIES B PREFERRED STOCK AND WARRANT PURCHASE AGREEMENT DATED
     DECEMBER 17, 1996, TOGETHER WITH ALL EXHIBITS THERETO ( THE "PURCHASE
     AGREEMENT") BETWEEN THE COMPANY AND SYNOPSYS, INC., WHICH FIXES THE RIGHTS
     AND OBLIGATIONS OF THE COMPANY AND THE HOLDER OF THIS WARRANT.  A COPY OF
     THE PURCHASE AGREEMENT IS ON FILE AT THE COMPANY'S PRINCIPAL OFFICE AND
     WILL BE FURNISHED TO THE HOLDER HEREOF UPON WRITTEN REQUEST TO THE
     CORPORATION.


                          VLSI LIBRARIES INCORPORATED

                            PREFERRED STOCK WARRANT

       Warrant to Purchase 50,000 Shares of Series B Preferred Stock and
          an Additional Variable Amount of Shares of Preferred Stock


     This Warrant hereby certifies that for value received, Synopsys, Inc.
("Synopsys" or the "Holder") is entitled to purchase from VLSI Libraries
Incorporated (the "Company"):

     (1) Up to 50,000 shares of the Company's Series B Preferred Stock  at the
exercise price of $3.77 per share, subject to Section 2.1 below; and

     (2) Subsequent to the issuance of the 50,000 shares of Series B Preferred
Stock and subject to Section 2.1 below, Additional Shares of Preferred Stock of
the Company at the price per share determined for such series of Preferred Stock
at the time of issuance.

     The number of shares purchasable upon any exercise of the rights set forth
in (1) and (2) above shall be limited to such number of shares of Preferred
Stock that, when combined with  (x) the number of shares of Series B Preferred
Stock originally purchased by Synopsys under the Purchase Agreement, and (y) any
additional shares of Preferred Stock of the Company purchased by Synopsys after
the date hereof in connection with this Warrant or otherwise, will increase
Synopsys' aggregate percentage ownership to 9.9% (the "Gross-Up Percentage") of
the Company's issued and outstanding capital stock at the time of such exercise.
Notwithstanding the foregoing, in the event Synopsys fails to exercise this
Warrant for the full number of Warrant Shares which could be issued upon receipt
of a Notice of Exercisability as described in Section 2.2 below, Synopsys shall
forfeit the right to purchase such Warrant Shares and Synopsys' Gross-Up
Percentage for purposes of future exercises of this Warrant shall 
<PAGE>
 
be decreased to the percentage ownership by Synopsys of the Company's issued and
outstanding capital stock following the event which gave rise to the Notice of
Exercisability.

     This Warrant has been issued pursuant to the Purchase Agreement and is
subject to the terms and conditions, and entitled to the benefits, thereof,
including provisions providing certain information and other rights.  A copy of
the Purchase Agreement is available for inspection at the principal office of
the Company and will be furnished without charge to the Holder upon written
request to the Company. Capitalized terms used but not defined herein shall have
the meaning given to them in the Purchase Agreement.

                                   Section 1

                                  DEFINITIONS

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

     "Additional Shares of Preferred Stock"  shall mean a series of Preferred
      ------------------------------------                                   
Stock issued upon exercise of this Warrant subsequent to the issuance of 50,000
shares of Series B Preferred Stock, which new series shall be essentially
identical to the Series B Preferred Stock with only such changes as shall be
necessary to reflect a different per share price of such series of Preferred
Stock.  Notwithstanding the foregoing, however, in the event of an exercise of
this Warrant in conjunction with the Company's first underwritten public
offering pursuant to an effective registration statement filed under the
Securities Act (the "IPO"), such Additional Shares of Preferred Stock shall
instead be issued as shares of Common Stock of the Company.

     "Closing Date"  shall mean December 17, 1996, or such other date as agreed
      ------------                                                             
upon by the parties.

     "Executive Officer"  shall mean, with respect to the Company, its President
      -----------------                                                         
or Chief Financial Officer.

     "Exercise Form"  shall mean the exercise form attached as Schedule 1
      -------------                                                      
hereto.

     "Exercise Price"  shall mean (i) on the purchase of the 50,000 shares of
      --------------                                                         
Series B Preferred Stock, $3.77 per share, (ii) on the issuance of Additional
Shares of Preferred Stock, the price per share determined for such series of
Preferred Stock at the time of issuance, provided that all other purchasers of
such series pay the same consideration, and (iii) on an issuance of Additional
Shares of Preferred Stock in conjunction with an IPO, the public offering price
per share less any underwriting discounts and commissions.  With respect to the
issuance of Additional Shares of Preferred Stock in the event of: (i) a
Financing (as defined in Section 2.1 below), the Exercise Price will be the per
share price prevailing in the Financing; (ii) an Annual Gross-Up (as defined in
Section 2.1 below), the Exercise Price will be the fair market value of the
Additional Shares of Preferred Stock as determined in good faith by the Board of
Directors without reference to a control premium;  (iii) an Offensive
Acquisition (as defined in Section 2.1 below), the Exercise Price will be the
fair market value of the Additional Shares of Preferred Stock as determined in
good faith by the Board of Directors with reference to the value 

                                      -2-

received by the Company in the Offensive Acquisition in return for the shares of
the Company's capital stock issued therefor; or (iv) a Defensive Merger (as
defined immediately below), the Exercise Price will be the fair market value of
the Additional Shares of Preferred as determined in good faith by the Board of
Directors with reference to the value received by the Company in the Defensive
Merger in exchange for the shares of the Company's capital stock.

     "Expiration Date"  shall mean the earlier of (i) the closing of the
      ---------------                                                   
Company's sale of its Common Stock in an IPO or (ii) the closing of a merger or
consolidation of the Company with or into any other corporation or other entity
or person, or any other corporate reorganization in which the Company shall not
be the surviving or continuing entity of such merger, consolidation or
reorganization (a "Defensive Merger");  provided, however, that this Warrant may
be exercised in conjunction with an IPO or a Defensive Merger as provided in
Section 2.1 below.

     "Holder"  shall mean Synopsys, Inc.
      ------                            

     "Person"  shall mean an individual or a corporation, association,

      --------------                                                           
issued or issuable upon exercise of this Warrant in accordance with Section 2.1,
and any Additional Shares of Preferred Stock issued pursuant to this Warrant.

                                   Section 2

                              EXERCISE OF WARRANT

     Section 2.1    Exercisability of Warrant.
                    ------------------------- 

                    (a) As of the date of issuance of this Warrant, (i) Synopsys
is the holder of 9.9% of the Company's issued and outstanding capital stock, and
(ii) the Company has reserved for future issuance 1,677,646 shares of Common
Stock upon exercise of options issued or to be issued pursuant to the Company's
1993 Stock Option Plan (the "Plan"). This Warrant shall be exercisable upon the
occurrence of any of the events listed in Section 2.1(b) below to enable
Synopsys to purchase additional shares of capital stock of the Company to
maintain its Gross-Up Percentage, solely where the dilution is caused by the
issuance of up to 1,677,646 shares of Common Stock upon the exercise of stock
options issued under the Plan.

                    (b) This Warrant shall become exercisable upon any of the
following events:

                        (i)   a Financing - involving the issuance of capital
stock by the Company for the primary purpose of raising financing, as opposed to
debt financing transactions, capital equipment lease transactions, technology
license agreements or strategic partner transactions;

                                      -3-
<PAGE>
 
                        (ii)   an Offensive Acquisition - involving the
issuances of capital stock by the Company in connection with a merger or
consolidation with or an acquisition of another corporation, entity or person,
where the Company is the surviving or continuing entity of such merger,
consolidation or acquisition;

                        (iii)  an Annual Gross-Up - which shall occur at the end
of each fiscal year of the Company in which there has not been a Financing or an
Offensive Acquisition;

                        (iv)   an IPO; and

                        (v)    a Defensive Merger.

               (c)  Upon the occurrence of any of the events described in
subsection (b) above, the Company shall deliver a Notice of Exercisability to
Synopsys: (i) in the case of a Financing or Offensive Acquisition, not less than
10 days prior to the closing thereof, (ii) in the case of an Annual Gross-Up,
within 30 days after completion by the Company of its annual audit for that
fiscal year, (iii) in the case of an IPO, not less than 10 days prior to the
filing of the registration statement with the Securities and Exchange
Commission, and (iv) in the case of a Defensive Merger, not less than 10 days
prior to the execution of a definitive acquisition agreement.

     Section 2.2    Exercise of Warrant.
                    ------------------- 

                    (a) Upon receipt of a Notice of Exercisability from the
Company, the Holder may exercise this Warrant, in whole or in part, by
delivering to the Company a properly completed Exercise Form in the form of
Schedule 1 hereto and promptly, upon determination of the per share price
therefor, a check in the aggregate amount equal to the product obtained by
multiplying (i) the Exercise Price then in effect by (ii) the number of Warrant
Shares being purchased. An exercise in conjunction with an IPO or Defensive
Merger shall be made contingent upon the closing of such transaction.

                    (b) Holder shall have ten (10) business days from the
receipt of a Notice of Exercisability to elect to exercise this Warrant. The
closing date of such purchase of securities will be: (i) in the case of a
Financing, Offensive Acquisition, IPO or Defensive Merger, the same date as the
closing of any such transaction, and (ii) in the event of an Annual Gross-Up,
the closing shall occur as soon as possible, but not later than five (5)
business days after receipt of consent of the shareholders of the Company to
amend the Company's Restated Articles of Incorporation to authorize the
Additional Shares of Preferred Stock to be issued to Synopsys upon exercise of
this Warrant.

                    (c) The Company shall not be required to issue fractional
Warrant Shares upon the exercise of the Warrant.

                    (d) The Company shall pay all taxes (other than any
applicable income or similar taxes payable by a holder of a Warrant)
attributable to the initial issuance of Warrant Shares upon the exercise of the
Warrant; provided, however, that the Company shall not be required to pay any 
         --------  ------- 
tax 

                                      -4-
<PAGE>
 
which may be payable in respect of any transfer involved in the issuance of any
Warrant or any certificate for Warrant Shares in a name other than that of the
Holder of the Warrant.

     Section 2.3    Authorization of Additional Shares of Preferred Stock.  At
                    -----------------------------------------------------     
such time as Holder is entitled to purchase Additional Shares of Preferred Stock
pursuant to this Warrant, and in the event such Additional Shares of Preferred
Stock are not being purchased pursuant to a Financing, the Company shall
promptly prepare an amendment to its Restated Articles of Incorporation (the
"Articles") to establish a new series of Preferred Stock which shall constitute
the Additional Shares of Preferred Stock which the Holder is entitled to acquire
at that time, and the Company shall promptly solicit the approval of the
shareholders of the Company to the establishment of such additional series of
Preferred Stock and to the filing of such amendment to the Articles and shall
take such other actions as may be reasonably necessary to establish a new series
of Preferred Stock in accordance with the requirements of the California
Corporations Code and the Company's Articles and Bylaws.  In the event the
Company is unable to obtain the consent of the Company's shareholders to the
establishment of such additional series of Preferred Stock, the Company agrees
that Synopsys shall have the right to buy a number of shares of Common Stock
equivalent to the number of shares of such new series of Preferred Stock that
Synopsys would otherwise be entitled to acquire hereunder.

                                   Section 3

                       ADJUSTMENT OF EXERCISE PRICE AND
                           NUMBER OF WARRANT SHARES

     Section 3.1    The number of shares of Series B Preferred Stock purchasable
upon exercise of the Warrant shall be subject to adjustment from time to time in
accordance with this Section 3.

     Section 3.2    Subdivisions or Combinations
                    ----------------------------

                    If, at any time after the Closing Date, (a) the number of
shares of Common Stock or Preferred Stock outstanding is increased by a dividend
or other distribution payable in shares of Common Stock or Preferred Stock or by
a subdivision or split-up of shares of Common Stock or Preferred Stock, or (b)
the number of shares of Common Stock or Preferred Stock outstanding is decreased
by a combination or reverse stock split of shares of Common Stock or Preferred
Stock, then, in each case, effective as of the effective date of such event
retroactive to the record date, if any, of such event, (i) the Exercise Price of
the Series B Preferred Stock shall be adjusted to a price determined by
multiplying (A) the Exercise Price in effect immediately prior to such event by
(B) a fraction, the numerator of which shall be the number of shares of Common
Stock and Preferred Stock outstanding immediately prior to such event and the
denominator of which shall be the number of shares of Common Stock or Preferred
Stock outstanding after giving effect to such event, and (ii) the number of
shares of Series B Preferred Stock subject to purchase upon the exercise of the
Warrant shall be adjusted effective at such time, to a number equal to the
product of (A) the number of shares of Series B Preferred Stock subject to
purchase upon the exercise of the Warrant immediately prior to such event by (B)
a fraction, the numerator of which shall be the number of shares of Common Stock
and Preferred Stock outstanding

                                      -5-
<PAGE>
 
after giving effect to such event and the denominator of which shall be the
number of shares of Common Stock and Preferred Stock outstanding immediately
prior to such event.

     Section 3.3    Capital Reorganization or Capital Reclassifications.
                    --------------------------------------------------- 

                    If, at any time after the Closing Date, there shall be any
capital reorganization or any reclassification of the capital stock of the
Company (other than a change in par value or from par value to no par value or
from no par value to par value or as a result of a stock dividend or
subdivision, split-up or combination of shares), then in each case the Company
shall cause effective provision to be made so that the Warrant shall, effective
as of the effective date of such event retroactive to the record date, if any,
of such event, be exercisable for the kind and number of shares of stock, other
securities, cash or other property, to which a holder of the number of shares of
Series B Preferred Stock deliverable upon exercise of such Warrant would have
been entitled upon such reorganization or reclassification and any such
provision shall include adjustments in respect of such stock, securities or
other property that shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Agreement with respect to such Warrant.

     Section 3.4    Notice of Adjustment
                    --------------------

                    Whenever the Exercise Price and the number of shares of
Series B Preferred Stock shall be adjusted as provided in this Section, the
Company shall provide to the Holder a statement, signed by an Executive Officer,
describing in detail the facts requiring such adjustment and setting forth a
calculation of the Exercise Price and the number of shares of Series B Preferred
Stock applicable to the Warrant after giving effect to such adjustment. All

          RE:  REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-1 to be filed by you
with the Securities and Exchange Commission on November 26, 1997 (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of 3,335,000 shares of Common Stock of
Artisan Components, Inc. (the "Shares").  As your counsel in connection with
this transaction, we have examined the proceedings proposed to be taken in
connection with said sale and issuance of the Shares.

     It is our opinion that, upon completion of the proceedings being taken or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, and upon completion of the proceedings being taken in order to permit
such transactions to be carried out in accordance with the securities laws of
various states, where required, the Shares when issued and sold in the manner
referred to in the Registration Statement will be legally and validly issued,
fully paid and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement, including the prospectus constituting a part thereof,
and any amendment thereto.

                              Very truly yours,

                              WILSON, SONSINI, GOODRICH & ROSATI

                           ARTISAN COMPONENTS, INC.

                           INDEMNIFICATION AGREEMENT


     This Indemnification Agreement ("Agreement") is effective as of February
__, 1998 by and between Artisan Components, Inc., a Delaware corporation (the
"Company"), and __ ("Indemnitee").

     WHEREAS, effective as of the date hereof, Artisan Components, Inc. a
California corporation, is reincorporating into Delaware;

     WHEREAS, the Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and its related
entities;

     WHEREAS, in order to induce Indemnitee to continue to provide services to
the Company, the Company wishes to provide for the indemnification of, and the
advancement of expenses to, Indemnitee to the maximum extent permitted by law;

     WHEREAS, the Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for the Company's directors, officers, employees,
agents and fiduciaries, the significant increases in the cost of such
insurance and the general reductions in the coverage of such insurance;

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

     WHEREAS, in connection with the Company's reincorporation, the Company and
Indemnitee desire to continue to have in place the additional protection
provided by an indemnification agreement, with such changes as are required to
conform the existing agreement to Delaware law and to provide indemnification
and advancement of expenses to the Indemnitee to the maximum extent permitted by
Delaware law;

     WHEREAS, in view of the considerations set forth above, the Company desires
that Indemnitee shall be indemnified and advanced expenses by the Company as set
forth herein;

     NOW, THEREFORE, the Company and Indemnitee hereby agree as set forth below.

     1.   Certain Definitions.
          ------------------- 

          a.   "Change in Control" shall mean, and shall be deemed to have
occurred if, on or after the date of this Agreement, (i) any "person" (as such
term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934,
as amended), other than a trustee or other fiduciary holding securities under an
employee benefit plan of the Company acting in such capacity or a corporation
<PAGE>
 
owned directly or indirectly by the stockholders of the Company in substantially
the same proportions as their ownership of stock of the Company, becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing more than 50% of the total
voting power represented by the Company's then outstanding Voting Securities,
(ii) during any period of two consecutive years, individuals who at the
beginning of such period constitute the Board of Directors of the Company and
any new director whose election by the Board of Directors or nomination for
election by the Company's stockholders was approved by a vote of at least two
thirds (2/3) of the directors then still in office who either were directors at
the beginning of the period or whose election or nomination for election was
previously so approved, cease for any reason to constitute a majority thereof,
(iii) the stockholders of the Company approve a merger or consolidation of the
Company with any other corporation other than a merger or consolidation which
would result in the Voting Securities of the Company outstanding immediately
prior thereto continuing to represent (either by remaining outstanding or by
being converted into Voting Securities of the surviving entity) at least 80% of
the total voting power represented by the Voting Securities of the Company or
such surviving entity outstanding immediately after such merger or
consolidation, or (iv) the stockholders of the Company approve a plan of
complete liquidation of the Company or an agreement for the sale or disposition
by the Company of (in one transaction or a series of related transactions) all
or substantially all of the Company's assets.

          b.   "Claim" shall mean with respect to a Covered Event:  any
threatened, pending or completed action, suit, proceeding or alternative dispute
resolution mechanism, or any hearing, inquiry or investigation that Indemnitee
in good faith believes might lead to the institution of any such action, suit,
proceeding or alternative dispute resolution mechanism, whether civil, criminal,
administrative, investigative or other.

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

          d.   "Covered Event" shall mean any event or occurrence related to the
fact that Indemnitee is or was a director, officer, employee, agent or fiduciary
of the Company, or any subsidiary of the Company, or is or was serving at the
request of the Company as a director, officer, employee, agent or fiduciary of
another corporation, partnership, joint venture, trust or other enterprise, or
by reason of any action or inaction on the part of Indemnitee while serving in
such capacity.

          e.   "Expenses" shall mean any and all expenses (including attorneys'
fees and all other costs, expenses and obligations incurred in connection with
investigating, defending, being a witness 

                                      -2-
<PAGE>
 
in or participating in (including on appeal), or preparing to defend, to be a
witness in or to participate in, any action, suit, proceeding, alternative
dispute resolution mechanism, hearing, inquiry or investigation), judgments,
fines, penalties and amounts paid in settlement (if such settlement is approved
in advance by the Company, which approval shall not be unreasonably withheld) of
any Claim and any federal, state, local or foreign taxes imposed on the
Indemnitee as a result of the actual or deemed receipt of any payments under
this Agreement.

          f.   "Expense Advance" shall mean a payment to Indemnitee pursuant to
Section 3 of Expenses in advance of the settlement of or final judgement in any
action, suit, proceeding or alternative dispute resolution mechanism, hearing,
inquiry or investigation which constitutes a Claim.

          g.   "Independent Legal Counsel" shall mean an attorney or firm of
attorneys, selected in accordance with the provisions of Section 2(d) hereof,
who shall not have otherwise performed services for the Company or Indemnitee
within the last three years (other than with respect to matters concerning the
rights of Indemnitee under this Agreement, or of other Indemnitees under similar
indemnity agreements).

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

          i.   "Reviewing Party" shall mean, subject to the provisions of
Section 2(d), any person or body appointed by the Board of Directors in
accordance with applicable law to review the Company's obligations hereunder and
under applicable law, which may include a member or members of the Company's
Board of Directors, Independent Legal Counsel or any other person or body not a
party to the particular Claim for which Indemnitee is seeking indemnification.

          j.   "Section" refers to a section of this Agreement unless otherwise
indicated.

          k.   "Voting Securities" shall mean any securities of the Company that
vote generally in the election of directors.

     2.   Indemnification.
          --------------- 

          a.   Indemnification of Expenses.  Subject to the provisions of
               ---------------------------                               
Section 2(b) below, the Company shall indemnify Indemnitee for Expenses to the
fullest extent permitted by law if Indemnitee was or is or becomes a party to or
witness or other participant in, or is threatened to be made a party to or
witness or other participant in, any Claim (whether by reason of or arising in
part out of a 

                                      -3-
<PAGE>
 
Covered Event), including all interest, assessments and other charges paid or
payable in connection with or in respect of such Expenses.

          b.   Review of Indemnification Obligations.  Notwithstanding the
               -------------------------------------                      
foregoing, in the event any Reviewing Party shall have determined (in a written
opinion, in any case in which Independent Legal Counsel is the Reviewing Party)
that Indemnitee is not entitled to be indemnified hereunder under applicable
law, (i) the Company shall have no further obligation under Section 2(a) to make
any payments to Indemnitee not made prior to such determination by such
Reviewing Party, and (ii) the Company shall be entitled to be reimbursed by
Indemnitee (who hereby agrees to reimburse the Company) for all Expenses
theretofore paid to Indemnitee to which Indemnitee is not entitled hereunder
under applicable law; provided, however, that if Indemnitee has commenced or
                      --------  -------                                     
thereafter commences legal proceedings in a court of competent jurisdiction to
secure a determination that Indemnitee is entitled to be indemnified hereunder
under applicable law, any determination made by any Reviewing Party that
Indemnitee is not entitled to be indemnified hereunder under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expenses theretofore paid in indemnifying Indemnitee until a
final judicial determination is made with respect thereto (as to which all
rights of appeal therefrom have been exhausted or lapsed).  Indemnitee's
obligation to reimburse the Company for any Expenses shall be unsecured and no
interest shall be charged thereon.

          c.   Indemnitee Rights on Unfavorable Determination; Binding Effect.
               --------------------------------------------------------------  
If any Reviewing Party determines that Indemnitee substantively is not entitled
to be indemnified hereunder in whole or in part under applicable law, Indemnitee
shall have the right to commence litigation seeking an initial determination by
the court or challenging any such determination by such Reviewing Party or any
aspect thereof, including the legal or factual bases therefor, and, subject to
the provisions of Section 15, the Company hereby consents to service of process
and to appear in any such proceeding. Absent such litigation, any determination
by any Reviewing Party shall be conclusive and binding on the Company and
Indemnitee.

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

                                      -4-
<PAGE>
 
not be required to pay Expenses of more than one Independent Legal Counsel in
connection with all matters concerning a single Indemnitee, and such Independent
Legal Counsel shall be the Independent Legal Counsel for any or all other
Indemnitees unless (i) the employment of separate counsel by one or more
Indemnitees has been previously authorized by the Company in writing, or (ii) an
Indemnitee shall have provided to the Company a written statement that such
Indemnitee has reasonably concluded that there may be a conflict of interest
between such Indemnitee and the other Indemnitees with respect to the matters
arising under this Agreement.

          e.   Mandatory Payment of Expenses.  Notwithstanding any other
               -----------------------------                            
provision of this Agreement other than Section 10 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
Claim, Indemnitee shall be indemnified against all Expenses incurred by
Indemnitee in connection therewith.

     3.   Expense Advances.
          ---------------- 
 
          a.   Obligation to Make Expense Advances.  Upon receipt of a written
               -----------------------------------                            
undertaking by or on behalf of the Indemnitee to repay such amounts if it shall
ultimately be determined that the Indemnitee is not entitled to be indemnified
therefore by the Company hereunder under applicable law, the Company shall make
Expense Advances to Indemnitee.

          b.   Form of Undertaking.  Any obligation to repay any Expense
               -------------------                                      
Advances hereunder pursuant to a written undertaking by the Indemnitee shall be
unsecured and no interest shall be charged thereon.

          c.   Determination of Reasonable Expense Advances.  The parties agree
               --------------------------------------------                    
that for the purposes of any Expense Advance for which Indemnitee has made
written demand to the Company in accordance with this Agreement, all Expenses
included in such Expense Advance that are certified by affidavit of Indemnitee's
counsel as being reasonable shall be presumed conclusively to be reasonable.

     4.   Procedures for Indemnification and Expense Advances.
          --------------------------------------------------- 

          a.   Timing of Payments.  All payments of Expenses (including without
               ------------------                                              
limitation Expense Advances) by the Company to the Indemnitee pursuant to this
Agreement shall be made to the fullest extent permitted by law as soon as
practicable after written demand by Indemnitee therefor is presented to the
Company, but in no event later than thirty (30) business days after such written
demand by Indemnitee is presented to the Company, except in the case of Expense
Advances, which shall be made no later than ten (10) business days after such
written demand by Indemnitee is presented to the Company.

          b.   Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
               --------------------------------                         
condition precedent to Indemnitee's right to be indemnified or Indemnitee's
right to receive Expense Advances under this Agreement, give the Company notice
in writing as soon as practicable of any Claim made against Indemnitee for which
indemnification will or could be sought under this Agreement.  Notice to the

                                      -5-
<PAGE>
 
Company shall be directed to the Chief Executive Officer of the Company at the
address shown on the signature page of this Agreement (or such other address as
the Company shall designate in writing to Indemnitee).  In addition, Indemnitee
shall give the Company such information and cooperation as it may reasonably
require and as shall be within Indemnitee's power.

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

          d.   Notice to Insurers.  If, at the time of the receipt by the
               ------------------                                        
Company of a notice of a Claim pursuant to Section 4(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies.  The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of the Indemnitee, all amounts payable as a result of such Claim in
accordance with the terms of such policies.

          e.   Selection of Counsel.  In the event the Company shall be
               --------------------                                    
obligated hereunder to provide indemnification for or make any Expense Advances
with respect to the Expenses of any Claim, the Company, if appropriate, shall be
entitled to assume the defense of such Claim with counsel approved by Indemnitee
(which approval shall not be unreasonably withheld) upon the delivery to
Indemnitee of written notice of the Company's election to do so.  After delivery
of such notice, approval of such counsel by Indemnitee and the retention of such
counsel by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees or expenses of separate counsel subsequently retained by
or on behalf of Indemnitee with respect to the same Claim; provided that, (i)
Indemnitee shall have the right to employ Indemnitee's separate counsel in any
such Claim at Indemnitee's expense and (ii) if (A) the employment of separate
counsel by Indemnitee has been previously authorized by the Company, (B)
Indemnitee shall have reasonably concluded that there may be a conflict of
interest between the Company and Indemnitee in the conduct of any such defense,
or (C) the Company shall not continue to retain such counsel to defend such
Claim, then the fees and expenses of Indemnitee's separate counsel shall be
Expenses for which Indemnitee may receive indemnification or Expense Advances
hereunder.

     5.   Additional Indemnification Rights; Nonexclusivity.
          ------------------------------------------------- 

          a.   Scope.  The Company hereby agrees to indemnify the Indemnitee to
               -----                                                           
the fullest extent permitted by law, notwithstanding that such indemnification
is not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws or by statute.  In
the event of any change after the date of this Agreement in any applicable law,
statute or rule which expands the right of a Delaware corporation to indemnify a
member of its board of directors or an officer, employee, agent or fiduciary,
it is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits afforded by such change.  In the event of any
change in any applicable law, statute or rule which narrows the right of a
Delaware corporation to indemnify a member of its board of directors or an
officer, employee, agent or fiduciary, such change, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement, shall
have no effect on this Agreement or the parties' rights and obligations
hereunder except as set forth in Section 10(a) hereof.

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

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

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

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

     9.   Liability Insurance.  To the extent the Company maintains liability
          -------------------                                                
insurance applicable to directors, officers, employees, agents or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are provided to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, 

                                      -7-
<PAGE>
 
if Indemnitee is not a director of the Company but is an officer; or of the
Company's key employees, agents or fiduciaries, if Indemnitee is not an officer
or director but is a key employee, agent or fiduciary.

     10.  Exceptions.  Notwithstanding any other provision of this Agreement,
          ----------                                                         
the Company shall not be obligated pursuant to the terms of this Agreement:

          a.   Excluded Action or Omissions.  To indemnify or make Expense
               ----------------------------                               
Advances to Indemnitee with respect to Claims arising out of acts, omissions or
transactions for which Indemnitee is prohibited from receiving indemnification
under applicable law.

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

          c.   Lack of Good Faith.  To indemnify Indemnitee for any Expenses
               ------------------                                           
incurred by the Indemnitee with respect to any action instituted (i) by
Indemnitee to enforce or interpret this Agreement, if a court having
jurisdiction over such action determines as provided in Section 13 that each of
the material assertions made by the Indemnitee as a basis for such action was
not made in good faith or was frivolous, or (ii) by or in the name of the
Company to enforce or interpret this Agreement, if a court having jurisdiction
over such action determines as provided in Section 13 that each of the material
defenses asserted by Indemnitee in such action was made in bad faith or was
frivolous.

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

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

     12.  Binding Effect; Successors and Assigns.  This Agreement shall be
          --------------------------------------                          
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), spouses, heirs and
personal and legal representatives.  The Company shall require and cause any
successor (whether direct or indirect, and whether by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part, of
the business or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place.  This 

                                      -8-
<PAGE>
 
Agreement shall continue in effect regardless of whether Indemnitee continues to
serve as a director, officer, employee, agent or fiduciary (as applicable) of
the Company or of any other enterprise at the Company's request.

     13.  Expenses Incurred in Action Relating to Enforcement or Interpretation.
          --------------------------------------------------------------------- 
In the event that any action is instituted by Indemnitee under this Agreement or
under any liability insurance policies maintained by the Company to enforce or
interpret any of the terms hereof or thereof, Indemnitee shall be entitled to be
indemnified for all Expenses incurred by Indemnitee with respect to such action
(including without limitation attorneys' fees), regardless of whether Indemnitee
is ultimately successful in such action, unless as a part of such action a court
having jurisdiction over such action makes a final judicial determination (as to
which all rights of appeal therefrom have been exhausted or lapsed) that each of
the material assertions made by Indemnitee as a basis for such action was not
made in good faith or was frivolous; provided, however, that until such final
judicial determination is made, Indemnitee shall be entitled under Section 3 to
receive payment of Expense Advances hereunder with respect to such action.  In
the event of an action instituted by or in the name of the Company under this
Agreement to enforce or interpret any of the terms of this Agreement, Indemnitee
shall be entitled to be indemnified for all Expenses incurred by Indemnitee in
defense of such action (including without limitation costs and expenses incurred
with respect to Indemnitee's counterclaims and cross-claims made in such
action), unless as a part of such action a court having jurisdiction over such
action makes a final judicial determination (as to which all rights of appeal
therefrom have been exhausted or lapsed) that each of the material defenses
asserted by Indemnitee in such action was made in bad faith or was frivolous;
provided, however, that until such final judicial determination is made,
Indemnitee shall be entitled under Section 3 to receive payment of Expense
Advances hereunder with respect to such action.

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

     15.  Notice.  All notices, requests, demands and other communications under
          ------                                                                
this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and signed for by the party addressed, on the date of such
delivery, or (ii) if mailed by domestic certified or registered mail with
postage prepaid, on the third business day after the date postmarked.  Addresses
for notice to either party are as shown on the signature page of this Agreement,
or as subsequently modified by written notice.

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

                                      -9-
<PAGE>
 
     17.  Severability.  The provisions of this Agreement shall be severable in
          ------------                                                         
the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including without limitation each portion of this Agreement containing any
provision held to be invalid, void or otherwise unenforceable, that is not
itself invalid, void or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal or
unenforceable.

     18.  Choice of Law.  This Agreement, and all rights, remedies, liabilities,
          -------------                                                         
powers and duties of the parties to this Agreement, shall be governed by and
construed in accordance with the laws of the State of Delaware as applied to
contracts between Delaware residents entered into and to be performed entirely
in the State of Delaware without regard to principles of conflicts of laws.

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

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

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

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

    4.  Administration of the Plan.
        -------------------------- 

        (a) Procedure.
            --------- 

            (i)    Multiple Administrative Bodies. The Plan may be administered
                   ------------------------------
by different Committees with respect to different groups of Employees and
Consultants.

            (ii)   Section 162(m). To the extent that the Administrator
                   --------------
determines it to be desirable to qualify Options granted hereunder as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administered by a Committee of two or more "outside
directors" within the meaning of Section 162(m) of the Code.

            (iii)  Rule 16b-3.  To the extent desirable to qualify transactions
                   ----------                                                  
hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder
shall be structured to satisfy the requirements for exemption under Rule 16b-3.

            (iv)   Other Administration.  Other than as provided above, the Plan
                   --------------------                                         
shall be administered by (A) the Board or (B) a Committee, which committee shall
be constituted to satisfy Applicable Laws.

                                      -3-
<PAGE>
 
        (b) Powers of the Administrator.  Subject to the provisions of the Plan,
            ---------------------------                                         
and in the case of a Committee, subject to the specific duties delegated by the
Board to such Committee, the Administrator shall have the authority, in its
discretion:

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

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

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

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

            (v)    to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any Option granted hereunder. Such terms and
conditions include, but are not limited to, the exercise price, the time or
times when Options 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 of the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

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

            (vii)  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;

            (viii) to institute an Option Exchange Program;

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

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

            (xi)   to modify or amend each Option (subject to Section 13 of the
Plan), including the discretionary authority to extend the post-termination
exercisability period of Options longer than is otherwise provided for in the
Plan;

            (xii)  to allow Optionees to satisfy withholding tax obligations by
electing to have the Company withhold from the Shares to be issued upon exercise
of an Option that number of Shares 

                                      -4-
<PAGE>
 
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined. All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable;

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

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

    5.  Eligibility.
        ----------- 

        (a) Nonstatutory Stock Options may be granted to Employees and
Consultants.  Incentive Stock Options may be granted only to Employees.  An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options.

        (b) Each Option shall be designated in the written option agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option.  However,
notwithstanding such designations, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year (under
all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options.  For purposes of this
Section 5(a), Incentive Stock Options shall be taken into account in the order
in which they were granted.  The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

        (c) Neither the Plan nor any Option shall confer upon an Optionee any
right with respect to continuing the Optionee's employment or consulting
relationship with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such employment or
consulting relationship at any time, with or without cause.

        (d) Upon the Company or a successor corporation issuing any class of
common equity securities required to be registered under Section 12 of the
Exchange Act, or upon the Plan being assumed by a corporation having a class of
common equity securities required to be registered under Section 12 of the
Exchange Act, the following limitations shall apply to grants of Options to
Employees:

            (i)   No Employee shall be granted, in any fiscal year of the
Company, Options to purchase more than 250,000 Shares (post-split).

            (ii)  In connection with his or her initial employment, an Employee
may be granted Options to purchase up to an additional 750,000 Shares (post-
split) which shall not count against the limit set forth in subsection (i)
above.

                                      -5-
<PAGE>
 
            (iii) The foregoing limitations shall be adjusted proportionately in
connection with any change in the Company's capitalization as described in
Section 11.

            (iv)  If an Option is canceled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 11), the canceled Option will be counted against the limits
set forth in subsections (i) and (ii) above. For this purpose, if the exercise
price of an Option is reduced, the transaction will be treated as a cancellation
of the Option and the grant of a new Option.

    6.  Term of Plan.  The Plan shall become effective upon the earlier to occur
        ------------                                                            
of its adoption by the Board of Directors or its approval by the shareholders of
the Company as described in Section 18 of the Plan.  It shall continue in effect
for a term of ten (10) years unless sooner terminated under Section 13 of the
Plan.

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

    8.  Option Exercise Price and Consideration.
        --------------------------------------- 

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

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

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

                                      -6-
<PAGE>
 
        (b) Waiting Period and Exercise Dates.  At the time an Option is
            ---------------------------------                           
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.  In so doing, the Administrator may specify that an
Option may not be exercised until the completion of a service period.

        (c) Form of Consideration.  The consideration to be paid for the Shares
            ---------------------                                              
to be issued upon exercise of an Option, including the method of payment, shall
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) promissory note, (4) other Shares which (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 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 said Option shall be exercised, (5) 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, (6) a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement, (7) any
combination of the foregoing methods of payment, or (8) such other consideration
and method of payment for the issuance of Shares to the extent permitted by
Applicable Laws.  In making its determination as to the type of consideration to
accept, the Administrator shall consider if acceptance of such consideration may
be reasonably expected to benefit the Company.

    9.  Exercise of Option.
        ------------------ 

        (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted
            -----------------------------------------------                    
hereunder shall be exercisable according to the terms of the Plan and at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.

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

            An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may, as authorized by the Board, consist of any
consideration and method of payment allowable under Section 8(b) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a 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 11 of the Plan.

                                      -7-
<PAGE>
 
            Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

        (b) Termination of Employment or Consulting Relationship.  In the event
            ----------------------------------------------------               
of termination of an Optionee's Continuous Status as an Employee or Consultant
with the Company (but not in the event of a change of status from Employee to
Consultant (in which case an Employee's Incentive Stock Option shall
automatically convert to a Nonstatutory Stock Option on the ninety-first (91st)
day following such change of status) or from Consultant to Employee), such
Optionee may, but only within such period of time as is determined by the
Administrator, of at least thirty (30) days, with such determination in the case
of an Incentive Stock Option not exceeding three (3) months after the date of
such termination (but in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise his or her Option to
the extent that Optionee was entitled to exercise it at the date of such
termination.  To the extent that Optionee was not entitled to exercise the
Option at the date of such termination, the Shares covered by the unexercisable
portion of the Option shall revert to the Plan, or if Optionee does not exercise
such Option to the extent so entitled within the time specified herein, the
Option shall terminate and the Shares covered by such Option shall revert to the
Plan.

        (c) Disability of Optionee.  Notwithstanding the provisions of Section
            ----------------------                                            
9(b) above, in the event of termination of an Optionee's Continuous Status as an
Employee or Consultant as a result of his total and permanent disability (as
defined in Section 22(e)(3) of the Code), Optionee may, but only within six (6)
months from the date of such termination (but in no event later than the
expiration date of the term of such Option as set forth in the Option
Agreement), exercise the Option to the extent otherwise entitled to exercise it
as of six (6) months after the date of such termination.  To the extent that
Optionee was not entitled to exercise the Option as of six (6) months after the
date of such termination, the Shares covered by the unexercisable portion of the
Option shall revert to the Plan, or if Optionee does not exercise such Option to
the extent so entitled within the time specified herein, the Option shall
terminate and the Shares covered by such Option shall revert to the Plan.

        (d) Death of Optionee.  In the event of termination of an Optionee's
            -----------------                                               
Continuous Status as an Employee or Consultant as a result of the death of an
Optionee (i) during the term of the Option and while an Employee of the Company
having been in Continuous Status as an Employee since the date of grant of the
Option, or (ii) within three (3) months after the termination of Optionee's
Continuous Status as an Employee for any reason other than for cause or a
voluntary termination initiated by the Optionee, 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 of the term of such Option as set forth in the
Option Agreement), by the Optionee's estate or by a person who acquired the
right to exercise the Option by bequest or inheritance, but only to the extent
the Optionee would have been entitled to exercise the Option as of six (6)
months after the date of death.  To the extent that Optionee was not entitled to
exercise the Option as of six (6) months after the date of death, the Shares
covered by the unexercisable portion of the Option shall revert to the Plan, or
if Optionee does not exercise such Option to the extent

                                      -8-
<PAGE>
 
so entitled within the time specified herein, the Option shall terminate and
the Shares covered by such Option shall revert to the Plan.

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

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

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

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

        (b) Dissolution or Liquidation.  In the event of the proposed
            --------------------------                               
dissolution or liquidation of the Company, the Board shall notify the Optionee
at least fifteen (15) days prior to such proposed action. To the extent it has
not been previously exercised, the Option will terminate immediately prior to
the consummation of such proposed action, unless otherwise provided by the
Board.  The Board may, in the exercise of its sole discretion in such instances,
declare that any Option shall terminate as of a date fixed by the Board and give
each Optionee the right to exercise his Option as to all or any part of the
Optioned Stock, including shares as to which the Option would not otherwise be
exercisable.

        (c) Merger. In the event of a merger of the Company with or into another
            -------                                                             
corporation, the Option shall be assumed or an equivalent option shall be
substituted by such successor corporation or a parent or subsidiary of such
successor corporation.  In the event that the successor corporation does not
agree to assume the Option or to substitute an equivalent option, the
Administrator shall, in lieu of 

                                      -9-
<PAGE>
 
such assumption or substitution, provide for the Optionee to have the right to
exercise the Option as to all or a portion of the Optioned Stock, including
Shares as to which it would not otherwise be exercisable. If the Administrator
makes an Option fully exercisable in lieu of assumption or substitution in the
event of a merger, the Administrator shall notify the Optionee that the Option
shall be fully exercisable for a period of fifteen (15) days from the date of
such notice, and the Option will terminate upon the expiration of such period.
For the purposes of this paragraph, the Option shall be considered assumed if,
following the merger, the option confers the right to purchase, for each Share
of Optioned Stock subject to the Option immediately prior to the merger, the
consideration (whether stock, cash, or other securities or property) received in
the merger by holders of Common Stock for each Share held on the effective date
of the transaction (and if holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the merger
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 the exercise of the Option, for each Share
of Optioned Stock subject to the Option, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger.

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

    13. Amendment and Termination of the Plan.
        ------------------------------------- 

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

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

    14. Conditions Upon Issuance of Shares.
        ---------------------------------- 

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

                                      -10-
<PAGE>
 
        (b) Investment Representations.  As a condition to the exercise of an
            --------------------------                                       
Option, the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required by any of the aforementioned relevant provisions of law.


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

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

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

    18. Shareholder Approval.  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 degree and manner required under applicable state and federal law and the
rules of any stock exchange upon which the Common Stock is listed.

                           ARTISAN COMPONENTS, INC.

                        INCENTIVE STOCK OPTION AGREEMENT



     Artisan Components, Inc., a California corporation (the "Company"), has

reference.  The terms defined in the Plan shall have the same defined meanings
herein.

     1.   Nature of the Option.  This Option is intended to qualify as an

Incentive Stock Option as defined in Section 422A of the Code.

     2.   Exercise Price.  The exercise price is $.01 for each share of Common
          --------------                                                      
Stock, which price is the fair market value per share of the Company's Common
Stock as of the date of grant as determined in good faith by the Board of
Directors of the Company.

     3.   Exercise of Option.  This Option shall be exercisable during its term
          ------------------                                                   
in accordance with the provisions of Section 8 of the Plan as follows:

          (i)  Right to Exercise.
               ----------------- 

               (a) Subject to Sections 3(i)(b) and (c) below, the Shares subject
to this Option shall become exercisable to the extent of 6.25% of the Shares
subject to the option for each quarter of Optionee's Continuous Status as an
Employee which has expired after __ (the "Vesting Commencement Date"); provided,
however, that this Option shall not be exercisable prior to one (1) year after
the Vesting Commencement Date.

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

               (c) In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by
Sections 7, 8 and 9 below, subject to the limitation contained in Section
3(i)(d).

               (d) In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in Section 14.

          (ii) Method of Exercise.  This Option shall be exercisable by written
               ------------------

<PAGE>
 
with respect to such shares of Common Stock as may be required by the Company
pursuant to the provisions of the Plan. Such written notice shall be signed by
the Optionee and shall be delivered in person to or received through certified
mail by the Secretary of the Company within the applicable time period set forth
herein. The written notice shall be accompanied by payment of the exercise
price.

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

     4.   Optionee's Representations.  In the event the Shares purchasable
          --------------------------                                      
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended, at the time this Option is exercised,
Optionee shall, concurrently with the exercise of all or any portion of this
Option, deliver to the Company his Investment Representation Statement in the
form attached hereto as Exhibit 2.

     5.   Method of Payment.  Payment of the exercise price shall be by any of
          -----------------                                                   
the following, or a combination thereof, at the election of the Optionee:

          (i)  cash;

(A) either have been owned by the Optionee for more than six (6) months on the
date of surrender or were not acquired, directly or indirectly, from the Company
and (B) 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.

     6.   Restrictions on Exercise.  This Option may not be exercised until such
          ------------------------                                              
time as the Plan has been approved by the shareholders of the Company, 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.

     7.   Termination of Status as an Employee.  If Optionee ceases to serve as
          ------------------------------------                                 
an Employee, he may, but only within three (3) months after the date he ceases
to be an Employee of the Company, exercise this Option to the extent that he was
entitled to exercise it at the date of such termination; provided, however, that
if such exercise of the Option would result in liability for the Employee or
Consultant under Section 16(b) of the Exchange Act, then such three (3) month
period shall be extended until the tenth (10th) day following the last date upon
which the Employee or Consultant has any liability under Section 16(b).  To the
extent that he was not entitled to exercise this Option at the date of such
termination, or if he does not exercise this Option within the time specified
herein, the Option shall terminate.

     8.   Disability of Optionee.  Notwithstanding the provisions of Section 7
          ----------------------                                              
above, if Optionee is unable to continue his employment with the Company as a
result of his total and permanent disability (as defined in Section 22(e)(3) of
the Internal Revenue Code), he may, but only within six (6) months from the date
of termination of employment, exercise his Option to the extent he was entitled
to exercise it as of six (6) months after the date of such termination.  To the
extent that he was not entitled to exercise the Option as of six (6) months
after the date of termination, or if he does not exercise such Option (which he
was entitled to exercise) within the time specified herein, the Option shall
terminate.

     9.   Death of Optionee.  In the event of the death of Optionee:
          -----------------                                         

          (i)  during the term of this Option and while an Employee of the
Company and having been in Continuous Status as an Employee since the date of
grant of the Option, the Option may be exercised, at any time within six (6)
months following the date of death, 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 that he would have been entitled to exercise it as of six (6) months
after the date of death; or

          (ii) within three (3) months after the termination of Optionee's
Continuous Status as an Employee for any reason other than for cause or a
voluntary termination initiated by the Optionee, the Option may be exercised, at
any time within six (6) months following the date of death, 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 that he would have been entitled to exercise
it as of six (6) months after the date of termination.

     10.  Right of First Refusal.  Before any Shares held by Optionee or any
          ----------------------                                            
transferee, in the event that Optionee has received the prior written consent of
the Company to transfer any Shares (either being sometimes referred to herein as
the "Holder"), may be sold or other wise transferred (excluding transfers by
bona fide gift or by opera-

                                       3
<PAGE>
 
tion 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
(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: (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
bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the "Offered Price"), and the Holder shall offer all of the
Shares proposed to be transferred to all Proposed Transferees at the Offered
Price 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 (unless the Holder consents), of the Shares proposed to be transferred in
the aggregate to 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 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
an appraiser mutually agreeable to both the Company and the Holder, with the
cost thereof split between the Company and the Holder.

          (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 90 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 all of the Proposed Transferees are not
purchased by the Company and/or its assignee(s) as provided in this Section,
then the Holder may sell or otherwise transfer such Shares to such Proposed
Transferees at the Offered Price or at a higher price, provided that (i) such
sale or other transfer is consummated within 120 days after the date of the
Notice and (ii) any such sale or other transfer is effected in accordance with
any applicable securities laws and the Proposed Transferees agree in writing
that the provisions of this Section shall continue to apply to the Shares in the
hands of such Proposed Transferees. If all of the Shares described in the Notice
are not transferred to the Proposed

                                       4
<PAGE>
 
Transferees within such period, 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.

     11.  Restrictive Legends and Stop-Transfer Orders.
          -------------------------------------------- 

          (i)  Legends.  Optionee understands and agrees that the Company shall
               -------                                                         
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together

     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR

          (ii)  Stop-Transfer Notices.  Optionee agrees that, in order to ensure
                ---------------------                                           
compliance with the restrictions referred to herein, the Company may issue

that, if the Company  transfers its own securities, it may make appropriate

          (iii) Refusal to Transfer.  The Company shall not be required (i) to

     12.  Market Standoff Agreement.  Optionee hereby agrees that if so
          -------------------------                                    
requested by the Company or any representative of the underwriters in connection
with any registration of the offering of any securities of the Company under the
Act, Optionee shall not sell or otherwise transfer any Shares or other
securities of the Company during the 180-day period following the effective date
of a registration statement of the Company filed under the Act; provided,
however, that such restriction shall only apply to the first two registration
statements of the Company to become effective under the Act which include
securities to be sold on behalf of the Company to the public in an underwritten
public offering under the Act.  The Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such 180-day period.

     13.  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 Optionee.  The terms of
this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee.

     14.  Term of Option.  This Option may not be exercised more than ten years
          --------------                                                       
from the date of grant of this Option, and may be exercised during such term
only in accordance with the Plan and the terms of this Option.

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

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

          (ii) Disposition of Shares.  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 and California
income tax purposes.  If Shares purchased under an ISO are disposed of within
such one-year period or within two years after the Date of Grant, any gain
realized on such disposition will be treated as compensation income (taxable at
ordinary income rates) to the extent of the excess, if any, of the 

                                     -6-
<PAGE>
 
fair market value of the Shares on the date of exercise over the Exercise 
Price.

          (iii) Notice of Disqualifying Disposition of ISO Shares.  If Optionee
                -------------------------------------------------              
sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on
or before the later of (1) the date two years after the Date of Grant, or (2)
the date on year after transfer of such Shares to the Optionee upon exercise of
the ISO, the Optionee shall immediately notify the Company in writing of such
disposition. Optionee agrees that Optionee may be subject to income tax
withholding by the Company on the compensation income recognized by the Optionee
from the early disposition by payment in cash or out of the current earnings
paid to the Optionee.

COMPANY      :  ARTISAN COMPONENTS, INC.
 
SECURITY     :  COMMON STOCK

AMOUNT       :

DATE         :


In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Seller and to the Company the following:

          (a)  I am aware of the Company's business affairs and financial
condition, and have acquired sufficient information about the Company to reach
an informed and knowledgeable decision to acquire the Securities.  I am
purchasing these Securities for my own account for investment purposes only and
not with a view to, or for the resale in connection with, any "distribution"
thereof for purposes of the Securities Act of 1933 ("Securities Act").

          (b)  I understand that the Securities have not been registered under
the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of my
investment intent as expressed herein.  In this connection, I understand that,
in the view of the Securities and Exchange Commission ("SEC"), the statutory
basis for such exemption may be unavailable if my representation was predicated
solely upon a present intention to hold these Securities for the minimum capital
gains period specified under tax statutes, for a deferred sale, for or until an
increase or decrease in the market price of the Securities, or for a period of
one year or any other fixed period in the future.

          (c)  I further understand that the Securities must be held
indefinitely unless subsequently registered under the Securities Act or
unless an exemption from registration is otherwise available. Moreover, I
understand that the Company is under no obligation to register the
Securities. In addition, I understand that the certificate 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.

<PAGE>
 
          (d)  I am familiar with the provisions of Rule 701 and Rule 144, each
promulgated under the Securities Act, which, in substance, permit limited public
resale of "restricted securities" acquired, directly or indirectly, from the
issuer thereof 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 later becomes
subject to the reporting requirements of Section 13 or 15(d) of the Securities
Exchange Act of 1934, ninety (90) days thereafter the securities exempt under
Rule 701 may be resold, 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), I acknowledge
and agree to the restrictions set forth in paragraph (c) hereof.

          In the event that the Company does not qualify under Rule 701 at the
time of issuance of the Securities, then the Securities may be resold 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 years after the party has
purchased, and made full payment for, 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)  I further understand that in the event all of the applicable
requirements of Rule 144 or Rule 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 Rule 144 and
Rule 701 are not exclusive, the Staff of the SEC 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 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.

                                     -2-
<PAGE>
 
          (f)  I understand that the certificate evidencing the Securities will
be imprinted with a legend which prohibits the transfer of the Securities
without the consent of the Commissioner of Corporations of California.  I have
read the applicable Commissioner's Rules with respect to such restriction, a
copy of which is attached.

                              Signature of Purchaser:

shall be eligible to participate in the Plan who was employed by the Company as
of the effective date of a registration statement filed with the Securities and
Exchange Commission for the initial offering of shares of Common Stock of the
Company to the public.

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

     4.   Offering Periods.  The Plan shall be implemented by consecutive,
          ----------------                                                
overlapping Offering Periods with a new Offering Period commencing on the first
Trading Day on or after February 1 and August 1 each year, or on such other date
as the Board shall determine, and continuing thereafter until terminated in
accordance with Section 20 hereof; provided, however, that the first Offering
Period under the Plan shall commence with the first Trading Day on or after the
date on which the Securities and Exchange Commission declares the Company's
Registration Statement effective and ending on the last Trading Day on or before
January 31, 2000.   The Board shall have the power to change the duration of
Offering Periods (including the commencement dates thereof) with respect to
future offerings without shareholder approval if such change is announced at
least five (5) days prior to the scheduled beginning of the first Offering
Period to be affected thereafter.

                                      -3-

     5.   Participation.
          ------------- 

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

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

     6.   Payroll Deductions.
          ------------------ 

          (a)   At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding fifteen percent (15%) of
the Compensation which he or she receives on each pay day during the Offering
Period.
                  
          (b) All payroll deductions made for a participant shall be credited to
his or her account under the Plan and shall be withheld in whole percentages
only.  A participant may not make any additional payments into such account.
                     
          (c) A participant may discontinue his or her participation in the Plan
as provided in Section 10 hereof, or may increase or decrease the rate of his or
her payroll deductions during the Offering Period by completing or filing with
the Company a new subscription agreement authorizing a change in payroll
deduction rate.  The Committee may, in its discretion, limit the number of
participation rate changes during any Offering Period.  The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly.  A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

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

          (e) At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock.  At any time,
the Company may, but will not be obligated to, withhold from the participant's
compensation the amount necessary 

                                      -4-
<PAGE>
 
for the Company to meet applicable withholding obligations, including any
withholding required to make available to the Company any tax deductions or
benefits attributable to sale or early disposition of Common Stock by the
Employee.

     7.   Grant of Option.  On the Enrollment Date of each Offering Period, each
          ---------------                                                       
eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than a
number of shares determined by dividing $12,500 by the Fair Market Value of a
share of the Company's Common Stock (subject to any adjustment pursuant to
Section 19) on the Enrollment Date, and provided further that such purchase
shall be subject to the limitations set forth in Sections 3(b) and 12 hereof.
Exercise of the option shall occur as provided in Section 8 hereof, unless the
participant has withdrawn pursuant to Section 10 hereof.  The option shall
expire on the last day of the Offering Period.

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

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

     10.  Withdrawal.
          ---------- 

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

                                      -5-
<PAGE>
 
          (b) A participant's withdrawal from an Offering Period shall not have
any effect upon his or her eligibility to participate in any similar plan which
may hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the participant
withdraws.

     11.  Termination of Employment.
          ------------------------- 

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

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

     13.  Stock.
          ----- 

          (a) Subject to Section19, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be six hundred thousand (600,000) shares (after giving effect to the one-
for-two reverse stock split approved by the shareholders on November 24, 1997),
together with  an annual increase to the number of shares reserved thereunder on
each anniversary date of the adoption of the Plan equal to the lesser of (i)
200,000 shares (post-split), (ii) one percent of the outstanding shares of the
Company on such date or (iii) a lesser amount determined by the Board.  If, on a
given Exercise Date, the number of shares with respect to which options are to
be exercised exceeds the number of shares then available under the Plan, the
Company shall make a pro rata allocation of the shares remaining available for
purchase in as uniform a manner as shall be practicable and as it shall
determine to be equitable.

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

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

     14.  Administration.
          -------------- 

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

                                      -6-
<PAGE>
 
made by the Board or its Committee shall, to the full extent permitted by law,
be final and binding upon all parties.

          (b) Rule 16b-3 Limitations.  Notwithstanding the provisions of
              ----------------------                                    
Subsection (a) of this Section 14, in the event that Rule 16b-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
any successor provision ("Rule 16b-3") provides specific requirements for
administrators of plans of this type, the Plan shall be only administered by
such a body and in such a manner as shall comply with the applicable
requirements of Rule 16b-3.  Unless permitted by Rule 16b-3, no discretion
concerning decisions regarding the Plan shall be afforded to any committee or
person that is not "disinterested" as that term is used in Rule 16b-3.

     15.  Designation of Beneficiary.
          -------------------------- 

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

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

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

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

     18.  Reports.  Individual accounts shall be maintained for each participant
          -------                                                               
in the Plan. Statements of account shall be given to participating Employees at
least annually, which statements shall

                                      -7-
<PAGE>
 
set forth the amounts of payroll deductions, the Purchase Price, the number of
shares purchased and the remaining cash balance, if any.

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

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

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

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

     20.  Amendment or Termination.
          ------------------------ 

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

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

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

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

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

                                      -9-

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

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

                                   ---------


                           ARTISAN COMPONENTS, INC.

                       1997 EMPLOYEE STOCK PURCHASE PLAN

                            SUBSCRIPTION AGREEMENT



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


1.   _____________________________________________________ hereby elects to
     participate in the Artisan Components, Inc. 1997 Employee Stock Purchase
     Plan (the "Employee Stock Purchase Plan") and subscribes to purchase shares
     of the Company's Common Stock in accordance with this Subscription
     Agreement and the Employee Stock Purchase Plan.

2.   I hereby authorize payroll deductions from each paycheck in the amount of
     ____% of my Compensation on each payday (from 1 to _____%) during the
     Offering Period in accordance with the Employee Stock Purchase Plan.
     (Please note that no fractional percentages are permitted.)

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

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

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

6.   I understand that if I dispose of any shares received by me pursuant to the
     Plan within 2 years after the Enrollment Date (the first day of the
     Offering Period during which I purchased such shares) or one year after the
     Exercise Date, I will be treated for federal income tax purposes as having
     received ordinary income at the time of such disposition in an amount equal
     to the excess of the fair market value of the shares at the time such
     shares were purchased by me over the price which I paid for the shares.  I
                                                                              -
     hereby agree to notify the Company in writing within 30 days after
     ---------------------------------------------------------------------------
<PAGE>
 
     the date of any disposition of my shares 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 sale or early disposition of Common Stock by me. If I
     dispose of such shares at any time after the expiration of the 2-year and
     1-year holding periods, I understand that I will be treated for federal
     income tax purposes as having received income only at the time of such
     disposition, and that such income will be taxed as ordinary income only to
     the extent of an amount equal to the lesser of (1) the excess of the fair
     market value of the shares at the time of such disposition over the
     purchase price which I paid for the shares, or (2) 15% of the fair market
     value of the shares on the first day of the Offering Period. The remainder
     of the gain, if any, recognized on such disposition will be taxed as
     capital gain.

under this Plan shall be automatic and nondiscretionary and shall be made
strictly in accordance with the following provisions:

                                      -2-
<PAGE>
 
              (i)   No person shall have any discretion to select which Outside
Directors shall be granted Options or to determine the number of Shares to be
covered by Options granted to Outside Directors.

              (ii)  Each Outside Director as of the effective date of this Plan,
as determined in accordance with Section 6 hereof, shall be automatically
granted an Option to purchase 25,000 (post-split) Shares (the "First Option") at
the initial public offering price of the Company's Common Stock. Each person who
becomes an Outside Director after the effective date of the initial public
offering shall be automatically granted an Option to purchase 25,000 Shares
(post-split) (such Option shall each be known as a "First Option") on the date
on which such person first becomes an Outside Director, whether through election
by the shareholders of the Company or appointment by the Board to fill a
vacancy; provided, however, that an Inside Director who ceases to be an Inside
Director but who remains a Director shall not receive a First Option.

              (iii) Each Outside Director shall be automatically granted an
Option to purchase 5,000 Shares (post-split)  (a "Subsequent Option") on the
date of the next meeting of the Board of Directors following the annual meeting
of shareholders of each year (beginning with the meeting for fiscal year 1998)
provided he or she is then an Outside Director and if as of such date, he or she
shall have served on the Board for at least the preceding six (6) months.

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

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

                    (A) the term of the First Option shall be ten (10) years.

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

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

                    (D) subject to Section 10 hereof, the First Option shall
become exercisable as to 25% of the shares subject to the Option on the first
anniversary of its date of grant and 1/48th of the Shares each month thereafter
so that the First Option shall be fully exercisable four (4) years after its
date of grant, provided that the Optionee continues to serve as a Director on
such dates.

              (vi)  The terms of a Subsequent Option granted hereunder
shall be as follows:

                                      -3-
<PAGE>
 
                    (A) the term of the Subsequent Option shall be ten (10)
years.

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

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

                    (D) subject to Section 10 hereof, the Subsequent Option
shall become exercisable as to 1/48th of the Shares subject to the Subsequent
Option on each monthly anniversary of its date of grant, provided that the
Optionee continues to serve as a Director on such dates.

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

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

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

     6.   Term of Plan.  The Plan shall become effective upon the effective date
          ------------                                                          
of the Company's initial public offering of its Common Stock that is registered
with the Securities and Exchange Commission.  It shall continue in effect for a
term of ten (10) years unless sooner terminated under Section 11 of the Plan.

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

                                      -4-

     8.   Exercise of Option.
          ------------------ 

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

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

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

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

          (b) Termination of Continuous Status as a Director.  Subject to
              ----------------------------------------------             
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or total and permanent disability (as
defined in Section 22(e)(3) of the Code)), the Optionee may exercise his or her
Option, but only within three (3) months following the date of such termination,
and only to the extent that the Optionee was entitled to exercise it on the date
of such termination (but in no event later than the expiration of its ten (10)
year term).  To the extent that the Optionee was not entitled to exercise an
Option on the date of such termination, and to the extent that the Optionee does
not exercise such Option (to the extent otherwise so entitled) within the time
specified herein, the Option shall terminate.

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

                                      -5-
<PAGE>
 
          (d) Death of Optionee.  In the event of an Optionee's death, the
              -----------------                                           
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term).  To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

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

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

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

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

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

                                      -6-
<PAGE>
 
Thereafter, the Option or option shall remain exercisable in accordance with
Sections 8(b) through (d) above.

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

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

     11.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a) Amendment and Termination.  The Board may at any time amend,
              -------------------------                                   
alter, suspend, or discontinue the Plan, but no amendment, alteration,
suspension, or discontinuation shall be made which would impair the rights of
any Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with any applicable
law,  regulation or stock exchange rule, the Company shall obtain shareholder
approval of any Plan amendment in such a manner and to such a degree as
required.

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

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

     13.  Conditions Upon Issuance of Shares.  Shares shall not be issued
          ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, state 

                                      -7-
<PAGE>
 
securities laws, and the requirements of any stock exchange upon which the
Shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

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

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

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

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

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

                                     LEASE

               THIS LEASE is made as of this 13th day of December 1995, between
               SPIEKER PROPERTIES, L.P., a California Limited (hereinafter
               called "Landlord")
                         Partnership
               and VLSI LIBRARIES   INCORPORATED, a California Corporation
               (hereinafter called "Tenant").

PREMISES       1.        Landlord leases to Tenant and Tenant leases from
                    Landlord those premises (hereinafter called "Premises)
                    outlined in red on Exhibit B attached hereto and made a part
                    hereof, specified in the Basic Lease Information attached
                    hereto (the "Building").

OCCUPANCY      2.        Tenant shall use the Premises for the Permitted Use and
                    for no other use or purpose without the prior written
                    consent of Landlord, which shall not be unreasonably
                    withheld or delayed. No increase in occupant density of the
                    Leased Premises shall be made which shall add to the burden
                    of such use of the Building as determined by Landlord
                    without the prior written consent of Landlord.

POSSESSION     3.   (a)  The parties project that the term shall commence on the
                    Scheduled Term Commencement Date and, except as otherwise
                    provided herein or in any exhibit or addendum hereto, shall
                    continue in full force until the Term Expiration Date. If
                    the Premises are not delivered by Landlord by the Scheduled
                    Term Commencement Date for any reason, Landlord shall not be
                    liable to Tenant for any loss or damage resulting from such
                    delay. The Term Commencement Date shall be the first day of
                    the calendar month next following the earlier of (i) the day
                    when the Premises are substantially complete, or (ii) the
                    date on which Tenant takes possession of, or commences the
                    operation of its business in some or all of the Premises. If
                    substantial completion occurs prior to the Scheduled Term
                    Commencement Dates, Tenant shall take occupancy. Landlord
                    shall provide Tenant as much notice as circumstances allow
                    of the date when Landlord expects to achieve substantial
                    completion based upon the progress of work. Should the Term
                    Commencement Date be a date other than the Scheduled Term
                    Commencement Date, either Landlord or Tenant, at the request
                    of the other shall execute a declaration specifying the Term
                    Commencement Date and the rent commencement date which shall
                    be binding upon the parties as to the matters therein
                    stated. Tenant's obligation to pay Rent and its other
                    obligations for payment under this Lease shall commence upon
                    the earlier of (i) the day when the Premises are
                    substantially complete, or (ii) the date on which Tenant
                    takes possession of or commences the operation of its
                    business in some or all of the Premises.

                    Tenant agrees to accept the premises in "as is" condition
                    except for the improvements per Exhibit C.

          RENT 4.        Tenant shall pay to Landlord throughout the Term Rent
                    as specified in the Basic Lease Information, payable in
                    monthly installments in advance on the first day of each
                    calendar month

See Addendum 1.     during every year of the Term in lawful money of the United
                    States, without deduction or offset whatsoever, to Landlord
                    at the address specified in the Basic Lease Information or
                    to such other firm or to such other place as Landlord may
                    from time to time designate in writing by notice given as
                    herein provided.  Rent for the first month of the Term shall
                    be paid by Tenant upon execution
<PAGE>
 
                    of this Lease. If the obligation for payment of Rent
                    commences on other than the first day of a month as provided
                    in paragraph 3(a), then Rent provided for such partial month
                    shall be prorated and the prorated installment shall be paid
                    on the first day of the calendar month next succeeding the
                    Term Commencement Date. If the Term terminates on other than
                    the last day of a calendar month, then the Rent provided for
                    such partial month shall be prorated and the prorated
                    installment shall be paid on the first day of the calendar
                    month next preceding the date of termination.

 RESTRICTIONS  5.        Tenant shall not do or permit anything to be done in or
       ON USE       about the Premises which will in any way obstruct or
                    interfere with the rights of other tenants or occupants of
                    the Building or injure or annoy them, nor use or allow the
                    Premises to be used for any improper, immoral, unlawful or
                    objectionable purpose, nor shall Tenant cause or maintain or
                    permit any nuisance in, on or about the Premises. Tenant
                    shall not commit or suffer the commission of any waste in,
                    on or about the Premises.

   COMPLIANCE  6.        Tenant shall not use the Premises or permit anything
    WITH LAWS       to be done in or about the Premises which will in any way
                    conflict with any law, statute, ordinance or governmental
                    rule or regulation now in force or which may hereafter be
See Addendum 2.     enacted or promulgated. Tenant shall not do or permit
                    anything to be done on or about the Premises or bring or
                    keep anything therein which will in any way increase the
                    rate of any insurance upon the Building or any of its
                    contents or cause a cancellation of said insurance or
                    otherwise affect said insurance in any manner, and Tenant
                    shall at its sole cost and expense promptly comply with all
                    laws, statutes, ordinances and governmental rules,
                    regulations or requirements now in force or which may
                    hereafter be in force and with the requirements of any board
                    of fire underwriters or other similar body now or hereafter
                    constituted relating to or affecting the condition, use or
                    occupancy of the Premises, excluding structural changes not
                    related to or affected by alterations or improvements made
                    by or for Tenant or Tenant's acts. The judgment of any court
                    of competent jurisdiction or the admission of Tenant in any
                    actions against Tenant, whether Landlord be a party thereto
                    or not, that Tenant has so violated any such law, statute,
                    ordinance, rule, regulation or requirement, shall be
                    conclusive of such violation as between Landlord and Tenant.

  ALTERATIONS  7.        Tenant shall not make or suffer to be made any
                    alterations, additions, or improvements in, on or to the
                    Premises or any part thereof without the prior written
                    consent of Landlord, which shall not be unreasonably
                    withheld or delayed; and any such alterations, additions or
                    improvements in, on or to said Premises, except for Tenant's
                    movable furniture and equipment, shall immediately become
                    Landlord's property and, at the end of the Term, shall
                    remain on the Premises without compensation to Tenant. In
                    the event Landlord consents to the making of any such
                    alterations, addition or improvement by Tenant, the same
                    shall be made by Tenant, at Tenant's sole cost and expense,
                    in accordance with plans and specifications approved by
                    Landlord, and any contractor or person selected by Tenant to
                    make the same must first be approved in writing by Landlord.

                    Notwithstanding the foregoing, at Landlord's option, all or
                    any portion of the alterations, addition or improvement work
                    shall be performed by Landlord for Tenant's account and
                    Tenant shall pay
<PAGE>
 
                    Landlord's estimate of the cost thereof (including a
                    reasonable charge for Landlord's overhead and profit) prior
                    to commencement of the work. Overhead and profit allowances
                    shall total fifteen percent (15%). Upon the expiration or
                    sooner termination of the Term, Tenant shall upon demand by
                    Landlord, at Tenant's sole cost and expense, with all due
                    diligence remove all those alterations, additions or
                    improvements made by or for the account of Tenant,
                    designated by Landlord to be removed, and Tenant shall with
                    all due diligence, at its sole cost and expense, repair and
                    restore the Premises to their original condition, normal
                    wear and tear excepted. At Landlord's election and
                    notwithstanding the foregoing, however, Tenant shall pay to
                    Landlord the cost of removing any such alterations,
                    additions or improvements and restoring the Premises to
                    their original condition, normal wear and tear excepted,
                    such cost to include a reasonable charge for Landlord's
                    overhead and profit as provided above, and such amount may
                    be deducted from the Security Deposit or any other sums or
                    amounts held by Landlord under this Lease.

      REPAIRS  8.        By taking possession of the Premises, Tenant accepts
                    the Premises as being in the condition in which Landlord is
                    obligated to deliver them and otherwise in good order,
                    condition and repair. At all times during the

<PAGE>
 
                    Term Tenant shall, at Tenant's sole cost and expense, keep
                    the Premises and every part thereof in good order, condition
                    and repair, excepting damage thereto by fire, earthquake,
                    act of God or the elements.  Tenant waives all rights it may
                    have under Section 1942 of the Civil Code of the State of
                    California and any similar law, statute or ordinance now or
                    hereafter in effect (to the full extent that such waiver may
                    lawfully be given) authorizing or purporting to authorize
                    Tenant to make repairs to or for the account of Landlord.
                    Tenant shall upon the expiration or sooner termination of
                    the Term hereof, unless Landlord demands otherwise pursuant
                    to paragraph 7 hereof, surrender to Landlord the Premises
                    and all repairs, changes, alterations, additions and
                    improvements thereto in the same condition as when received
                    or when first installed, damage by fire, earthquake, act of
                    God or the elements excepted.  Landlord has no obligation to
                    alter, remodel, improve, repair, decorate or paint the
                    Premises or any part thereof, except as specified in the
                    Office Lease Improvement Agreement and no representations
                    respecting the condition of the Premises or the Building
                    have been made by Landlord to Tenant, except as specifically
                    set forth herein or in the Office Lease improvement
                    Agreement.

        LIENS  9.        Tenant shall keep the Premises free from liens arising
                    out of or related to work performed, materials or supplies
                    furnished or obligations incurred by Tenant or in connection
                    with work made, suffered or done by Tenant in Premises or
                    Building.  In the event that Tenant shall not, within ten
                    (10) days following the imposition of any such lien, cause
                    the same to be released of record by payment or posing of a
                    proper bond, Landlord shall have, in addition to all
                    remedies provided herein and by law, the right, but no
                    obligation to cause the same to be released by such means as
                    it shall deem proper, including payment of the claim giving
                    rise to such lien Landlord shall have the right at all times
                    to post and keep posted on the Premises any notices
                    permitted or required by law, or which Landlord shall deem
                    proper, for the protection of Landlord, the Premises, the
                    Building and any other party having an interest therein,
                    from mechanics and materialmen's liens, and Tenant shall
                    give Landlord not less than ten (10) business days prior
                    written notice of the commencement of any work in the
                    Building or Premises which could lawfully give rise to a
                    claim for mechanics or materialmen's lien.

   ASSIGNMENT  10.       Tenant shall not sell, assign, encumber or otherwise
          AND       transfer this Lease or any interest therein (by operation of
   SUBLETTING       law or otherwise), sublet the Premises or any part thereof
                    or suffer any other person to occupy or use the Premises or
                    any portion thereof, nor shall Tenant permit any lien to be
                    placed on Tenant's interest under this Lease by operation of
                    law except in accordance with the provisions of this
                    paragraph 10. For purposes hereof, sales, transfers or
                    assignments of (i) a controlling interest in the stock of
                    Tenant, if Tenant is a corporation, or of (ii) the general
                    partnership interests sufficient to control management
                    decisions if Tenant is a partnership or of (iii) the
                    majority or controlling underlying beneficial interest, if
                    Tenant is any other form of business entity, shall
                    constitute an assignment subject to the terms of this
                    paragraph 10.

                    (a)  In the event that Tenant should desire to sublet the
                    Premises or any part thereof, Tenant shall provide Landlord
                    with written notice of such desire at least ninety (90) days
                    in advance of the
<PAGE>
 
                    date on which Tenant desires to make such sublease. Landlord
                    shall then have a period of thirty (30) days following
                    receipt of such notice within which to notify Tenant in
                    writing that Landlord elects either (i) to terminate this
                    Lease as to the space so affected as of the date so
                    specified by Tenant, in which event, Tenant shall be
                    relieved of all further obligations hereunder as to such
                    space from and after that date, or (ii) to permit Tenant to
                    sublet such space, subject however, to the prior written
                    approval of the proposed sublessee by Landlord which said
                    consent shall not be unreasonably withheld. If Landlord
                    should fail to notify Tenant in writing of its election
                    within said thirty (30) day period, Landlord shall be deemed
                    to have waived option (i) above, but written approval of the
                    proposed sublessee shall still be required. Refusal by
                    Landlord to approve a proposed sublessee shall not
                    constitute a termination of this Lease. In exercising its
                    right of consent to a sublessee it shall be reasonable for
                    Landlord to withhold consent to any sublessee who (aa) does
                    not agree to assume the obligations of the Lease with
                    respect to the space to be so sublet, (bb) does not agree to
                    utilize the space to sublet for the Permitted Use, (cc) is
                    of unsound financial condition as determined by Landlord or
                    (dd) will, in Landlord's opinion, increase the occupant
                    density in the Leased Premises. If Tenant proposes to
                    sublease less than all of the Premises, election by Landlord
                    of termination of this Lease with respect to space to be so
                    sublet shall leave this Lease in full force and effect with
                    respect to the remainder of the space, the Rent and Tenant's
                    Proportionate Share of Operating Expenses and taxes shall be
                    adjusted on a pro rata basis to reflect the reduction in Net
                    Rentable Area of the Premises as retained by Tenant. This
                    Lease as so amended shall continue thereafter in full force
                    and effect and references herein to the Premises shall mean
                    that portion thereof as to which the Lease has not been
                    terminated.

                    (b)  Tenant shall not enter into any other transaction
                    subject to this paragraph 10 without Landlord's prior
                    written consent which said consent shall not be unreasonably
                    withheld.  It shall be reasonable for Landlord to withhold
                    consent to any proposed transaction described in this
                    paragraph 10 on any of the grounds specified in paragraph 10
                    (a) with respect to sublessees or any other reasonable
                    grounds.

                    (c)  Any rent or other consideration realized by Tenant
                    under any such sublease or assignment to which Landlord has
                    consented hereunder, in excess of the Rent payable
                    hereunder, after amortization of the reasonable cost of the
                    improvements over the remainder of the Term for which Tenant
                    has paid and reasonable subletting and assignment costs,
                    shall be divided and paid ninety percent (90%) to Landlord
                    and ten percent (10%) to Tenant.

                    (d)  Any subletting hereunder by Tenant shall not result in
                    Tenant being released or discharged from any liability under
                    this lease.  Any purported assignment, subletting or other
                    transaction to which paragraph 10 applies, which occurs
                    contrary to the provisions hereof, shall be void.
                    Landlord's consent to any assignment, subletting or other
                    transaction to which this paragraph 10 applies shall not
                    release Tenant from any of Tenant's obligations hereunder or
                    constitute a consent with respect to any subsequent
                    transaction to which this paragraph applies.

INSURANCE AND  11.  (a)  Landlord shall not be liable to Tenant and Tenant
                    hereby

INDEMNIFICATION     waives all claims against Landlord for any injury or damage
                    to any person or properly in or about the Premises by or
                    from any cause whatsoever, (other than Landlord's gross
                    negligence or willful misconduct) and, without limiting the
                    generality of the foregoing, whether caused by water leakage
                    or any character from the roof, walls, basement or other
                    portion of the Premises or the Building, or caused by gas,
                    fire, oil or electricity in, on or about the Premises or the
                    Building.

                    (b)  Tenant shall hold Landlord harmless from and defend
                    Landlord against any and all claims or liability for any
                    injury or damage to any person or property whatsoever: (i)
                    occurring in, on or about the Premises or any part thereof,
                    or (ii) occurring in, on or about any facilities (including,
                    without prejudice to the generality of the term
                    "facilities", elevators, stairways, lobbies, health clubs,
                    passageways or hallways), the use of which Tenant may have
                    in conjunction with other tenants of the Building, when such
                    injury or damage shall be caused in part or whole by the
                    act, neglect, fault of or omission of any duty with respect
                    to the same by Tenant, its agents, servants, employees or
                    invitees.  Tenant shall further indemnify and save Landlord
                    harmless against and from  any and all claims by or on
                    behalf of any person, firm or corporation arising from the
                    conduct or management of any work or thing whatsoever done
                    by Tenant in or about or from transactions of Tenant
                    concerning the Premises, and will further indemnify and save
                    Landlord harmless against and from any and all claims
                    arising from any breach or default on the part of Tenant in
                    the performance of any covenant or agreement on the part of
                    Tenant to be performed pursuant to the terms of this Lease
                    or arising from any act or negligence of Tenant, or any of
                    its agents, contractors, servants, employees or licensees,
                    and from and against all costs, counsel fees, expenses and
                    liabilities incurred in connection with any such claim or
                    action or proceeding brought thereon.  In case any action or
                    proceeding is brought against Landlord by reason of any
                    claims or liability within the limits of the foregoing
                    indemnity, Tenant shall defend such action or proceeding at
                    Tenant's sole expense by counsel reasonably satisfactory to
                    Landlord.

                    (c)  Landlord shall hold Tenant harmless from and defend
                    Tenant against any and all claims or liability for any
                    injury or damage to any person or property occurring in or
                    about any facilities (including, without prejudice to the
                    generality of the term "facilities", elevators, stairways,

                    (b)  Provided Tenant shall not be in default hereunder, and
                    subject to the provisions elsewhere herein contained and to

                    installation and the cost of operation and maintenance
                    thereof, shall be paid by Tenant to Landlord upon demand by

                    machines, punch card machines and machines using excess
                    lighting or using current in excess of that which is
                    determined by Landlord as reasonable and normal for the
                    Permitted Use or which will in any way increase the amount

                    the Permitted Uses of the Premises; nor connect with
                    electric current, except through existing electrical outlets
                    in the Premises or what pipes, any apparatus or device for
                    the purposes of using electrical current or water.  If
                    Tenant shall require water or electric current or any other
                    resource in excess of that usually furnished or supplied for
                    the Permitted Uses of the Premises, Tenant shall first
                    procure the consent of Landlord which
<PAGE>
 
                    Landlord may refuse, to the use thereof, and Landlord may
                    cause a special meter to be installed in the Premises so as
                    to measure the amount of water, electric current or other
                    resource consumed for any such other use. Tenant shall pay
                    directly to Landlord as an addition to and separate from
                    payment of Basic Operating Cost the cost of all such energy,
                    utility service and meters (and of installation maintenance
                    and repair thereof). Landlord may add to the metered charge
                    a recovery of additional expense incurred in keeping account
                    of the water, electric current or other resource so
                    consumed. Landlord shall not be liable for any damages
                    directly or indirectly resulting from, nor shall the Rent
                    herein reserved be abated by reason of (i) the installation,
                    use or interruption of use of any equipment in connection
                    with the furnishing of any of the foregoing utilities and
                    services, (ii) failure to furnish or delay in furnishing any
                    such utilities or services when such failure or delay is
                    caused by acts of God or the elements, labor disturbances of
                    any character, any other accidents or other conditions
                    beyond the reasonable control of Landlord, or by the making
                    of repairs or improvements to the Premises or to the
                    Building, or (iii) the limitation, curtailment, rationing or
                    restriction on use of water, electricity, gas or any other
                    form of energy or any other service or utility whatsoever
                    serving the Premises or the Building. Landlord shall be
                    entitled to cooperate voluntarily and in a reasonable manner
                    with the efforts of national, state or local governmental
                    agencies or utility supplies in reducing energy or other
                    resources consumption. The obligation to make services
                    available hereunder shall be subject to the limitations of
                    any such voluntary, reasonable program.

                    (d)  Any sums payable under this paragraph 13 shall
                    constitute Additional Rent hereunder.

                    hereof, indicating thereon any exceptions thereto which may
                    exist at that time. Failure by Tenant to execute and deliver
                    such certificate shall constitute an acceptance of the
                    Premises and acknowledgment by Tenant that the statements
                    included in Exhibit D are true and correct without
                    exception. Landlord and Tenant intend that any statement
                    delivered pursuant to this paragraph may be relied upon by
                    any mortgagee, beneficiary, purchaser or prospective
                    purchaser of the Building or any interest therein, Landlord
                    shall have the right to substitute for the attached Exhibit
                    D a certificate in form required by Landlord's mortgagee or
                    provider financing.

                    (b) The New Premises shall be similar in area and in
                    appropriateness for Tenant's purposes;

                    (c) Any such substitution is effected for the purpose of

                    Landlord accepts any Rent from Tenant while Tenant is
                    holding over without Landlord's written consent.

SUBORDINATION  18.       Without the necessity of any additional document being

                    Building or the land upon which the Building is situated or
                    both, and (b) the lien of any mortgage or deed of trust

                    for any reason, or any mortgage or deed of trust is
                    foreclosed or a conveyance in lieu of foreclosure is made
                    for any reason, Tenant shall, notwithstanding any
                    subordination, attorn to and become the Tenant of the

                    the unpaid Rent which would have been earned after

                    competent evidence), plus

                    Basic Rent for the balance of the Term then remaining
                    ("Excess Gross Rental"), the assumed excess Gross Rental for
                    the calendar year of the default and each future calendar
                    year in the Term to be equal to the Excess Gross Rental for
                    the calendar year prior to the year in which default occurs
                    compounded at a per annum rate equal to the mean average
                    rate of inflation for the preceding five (5) calendar

                    years as determined by the United States Department of

                    (e)  LATE CHARGE.  In addition to its other remedies,
                    Landlord shall have the right without notice or demand to
                    add to the amount of any payment required to be made by
                    Tenant hereunder, and which is not paid on or before the
                    date the same is due, an amount equal to five percent (5%)
                    of the delinquency for each month or portion thereof that
                    the delinquency remains outstanding to compensate Landlord
                    for the loss of the use of the amount not paid and the
                    administrative costs caused by the delinquency, the parties
                    agreeing that the amount not paid and the administrative
                    costs caused by the delinquency, the parties agreeing that
                    Landlord's damage by virtue of such delinquencies would be
                    difficult to compute and the amount stated herein represents
                    a reasonable estimate thereof.

                    (f)  REMEDIES CUMULATIVE.  All rights, privileges and
                    elections or remedies of the parties are cumulative not
                    alternative to the extent permitted by law and except as

    DAMAGE BY  22.       If the Premises or the Building are damaged by fire or
   FIRE, ETC.       other casualty, Landlord shall forthwith repair the same,
                    provided such repairs can be made within one hundred eighty
                    (180) days from the date of such damage under the laws and
                    regulations of the federal, state and local governmental
                    authorities having jurisdiction thereof. In such event, this
                    Lease shall remain in full force and effect except that
                    Tenant shall be entitled to a proportionate reduction of
                    Rent while such repairs to be made hereunder by Landlord are
                    being made. Said proportionate reduction shall be based upon
                    the extent to which the making of such repairs to be made
                    hereunder by Landlord shall interfere with the business
                    carried on by Tenant in the Premises. Within twenty (20)
                    days from the date of such damage, Landlord shall notify
                    Tenant whether or not such repairs can be made within one
                    hundred eighty (180) days from the date of such damage and
                    Landlord's determination thereof shall be binding on Tenant.
                    If such repairs cannot be made within one hundred eighty
                    (180) days from the date of such damage, Landlord shall have
                    the option within thirty (30) days of the date of such
                    damage either to: (a) notify Tenant of Landlord's intention
                    to repair such damage and diligently prosecute such repairs,
                    in which event this Lease shall continue in full force and
                    effect and the Rent shall be reduced as provided herein; or
                    (b) notify Tenant of Landlord's election to terminate this
                    Lease as of a date specified in such notice, which date
                    shall be not less than thirty (30) nor more than sixty (60)
                    days after notice is given. In the event such notice to
                    terminate is given by Landlord, this Lease shall terminate
                    on the date specified in
<PAGE>
 
                    such notice.  In either event, the Rent shall be reduced by
                    a proportionate amount based upon the extent to which said
                    damage interfered with the business carried on by Tenant in
                    the Premises, and the Tenant shall pay such reduced Rent up
                    to the date of termination.  Landlord agrees to refund to
                    Tenant any Rent previously paid for any period of time
                    subsequent to such date of termination.  The repairs to be
                    made hereunder by Landlord shall not include, and Landlord
                    shall not be required to repair, any damage by fire or other
                    cause to the property of Tenant or any repairs or
                    replacements of any paneling, decorations, railings, floor
                    coverings or any alterations, additions, fixtures or
                    improvements installed on the premises by or at the expense
                    of Tenant.  The provisions of Section 1942, subdivision 2,
                    and Section 1933, subdivision 4, of the Civil Code of
                    California are superseded by the foregoing.

     EMINENT   23.       If any part of the Premises shall be taken or
      DOMAIN        appropriated under the power of eminent domain or conveyed
                    in lieu thereof, which materially effects Tenant's occupancy
                    of the Premises, either party shall have the right to
                    terminate this Lease at its option. If any part of the
                    Building shall be taken or appropriated under power of
                    eminent domain or conveyed in lieu thereof, Landlord may
                    terminate this Lease at its option. In either of such
                    events, Landlord shall receive subject to the rights of
                    Landlord's first mortgagee (and Tenant shall assign to
                    Landlord upon demand from Landlord) any income, rent, award
                    or any interest therein which may be paid in connection with
                    the exercise of such power of eminent domain, and Tenant
                    shall have no claim against Landlord for any part of the
                    sums paid by virtue of such proceedings, whether or not
                    attributable to the value of the unexpired Term. If a part
                    of the Premises shall be so taken or appropriated or
                    conveyed and neither party hereto shall elect to terminate
                    this Lease and the Premises have been damaged as a
                    consequence of such partial taking or appropriation or
                    conveyance. Landlord shall restore and Premises continuing
                    under this Lease at Landlord's cost and expense, provided,
                    however, that Landlord shall not be required to repair or
                    restore any injury or damage to the property of Tenant or to
                    make any repairs or restoration of any alterations,
                    additions, fixtures or improvements installed on the
                    Premises by or at the expense of Tenant. Thereafter, the
                    Rent for the remainder of the Term shall be proportionately
                    reduced, such reduction to be based upon the extent to which
                    the partial taking or appropriation or conveyance shall
                    interfere with the business carried on by Tenant in the
                    Premises. Notwithstanding anything to the contrary contained
                    in this paragraph, if the temporary use or occupancy of any
                    part of the Premises shall be taken or appropriated under
                    power of eminent domain during the Term, this Lease shall be
                    and remain unaffected by such taking or appropriation and
                    Tenant shall continue to pay in full all Rent payable
                    hereunder by Tenant during the Term, in the event of any
                    such temporary appropriation or taking. Tenant shall be
                    entitled to receive that portion of any award which
                    represents compensation for the use of or occupancy of the
                    Premises during the Term, and Landlord shall be entitled to
                    receive that portion of any award which represents the cost
                    of restoration of the Premises and the use and occupancy of
                    the Premises.
 
      SALE BY  24.       In the event of a sale or conveyance by Landlord of the
     LANDLORD       Building, the same shall operate to release Landlord from
 AND TENANT'S       any future liability upon any of the convenants or
                    conditions, express
<PAGE>
 
REMEDIES            or implied, herein contained in favor of Tenant, and in such
                    event Tenant agrees to look solely to the responsibility of
                    the successor in interest of Landlord in and to this Lease.
                    This Lease shall not be affected by any such sale and Tenant
                    agrees to attorn to the purchaser or assignee.  Tenant shall
                    look solely to Landlord's interest in the Building for
                    recovery of any judgment from Landlord.  Landlord, or if
                    Landlord is a partnership, its partners whether general or
                    limited, or if Landlord is a corporation, its directors,
                    officers or shareholders, shall never be personally liable
                    for any such judgment.

     RIGHT OF  25.       All convenants and agreements to be performed by
     LANDLORD       Tenant under any of the terms of this Lease shall be
   TO PERFORM       performed by Tenant at Tenant's sole cost and expense and
                    without any abatement of Rent. If Tenant shall fail to pay
                    any sum of money, other than Rent, required to be paid by it
                    hereunder or shall fail to perform any other act on its part
                    to be performed hereunder, and such failure shall continue
                    for ten (10) days after notice thereof by Landlord, Landlord
                    may, but shall not be obligated to do so, and without
                    waiving or releasing Tenant from any obligations of the
                    Tenant, make any such payment or perform any such act on the
                    Tenant's part to be made or performed. All sums so paid by
                    Landlord and all necessary incidental costs together with
                    interest thereon at the rate of eighteen percent (18%) per
                    annum or the maximum rate permitted by law, whichever is
                    less per annum from the date of such payment by the Landlord
                    shall be payable as Additional Rent to Landlord on demand,
                    and Tenant covenants to pay such sums, and Landlord shall
                    have, in addition to any other right or remedy of Landlord,
                    the same right and remedies in the event of the nonpayment
                    thereof by Tenant as in the case of default by Tenant in the
                    payment of the Rent.

    SURRENDER  26.  (a)  Tenant shall at least ninety (90) days before the
  OF PREMISES       last day of the Term, give to Landlord a written notice
                    intention to surrender the Premises on that date, but
                    nothing contained herein shall be construed as an extension
                    of the Term or as consent of Landlord to any holding over by
                    Tenant.

                    (b)  At the end of the term or any renewal thereof or other
                    sooner termination of this Lease, Tenant shall peaceably
                    deliver up to Landlord possession of the Premises, together
                    with all improvements, fixtures or additions thereto by
                    whomsoever made, in the same condition as received, or first
                    installed, damage by fire, earthquake, act of God, normal
                    wear and tear or the elements alone excepted. Tenant may,
                    upon the termination of this Lease, remove all movable
                    furniture and equipment belonging to Tenant, at Tenant's
                    sole cost, title to which shall be in Tenant until such
                    termination, repairing any damage caused by such removal.
                    Property not so removed shall be deemed abandoned by the
                    Tenant, and title to the same shall thereupon pass to
                    Landlord.

                    (c)  The voluntary or other surrender of this Lease by
                    Tenant, or a mutual cancellation thereof, shall not work a
                    merger and shall, at the option of Landlord, terminate all
                    or any existing subleases or subtenancies or may, at the
                    option of Landlord, operate as an assignment to it of any or
                    all such subleases or subtenancies.

       WAIVER  27.       If either Landlord or Tenant waives the performance of
                    any term, convenant or condition contained in this Lease,
                    such waiver shall not be deemed to be a waiver of any
                    subsequent breach of the
<PAGE>
 
                    same or any other term covenant or condition contained
                    herein. The acceptance of Rent by Landlord shall not
                    constitute a waiver of any preceding breach by Tenant of any
                    term, covenant or condition of this Lease, regardless of
                    Landlord's knowledge of such preceding breach at the time
                    Landlord accepted such rent. Failure by Landlord to enforce
                    any of the terms, covenants or conditions of this Lease for
                    any length of time shall not be deemed to waive or to
                    decrease the right of Landlord to insist thereafter upon
                    strict performance by Tenant. Waiver by Landlord of any
                    term, covenant or condition contained in this lease may only
                    be made by a written document signed by Landlord.

    NOTICES  28.         All notices and demands which may or are required to be
                    given by either party to the other hereunder shall be in

                    shall be sent by United States certified or registered mail,

                    determined by Landlord, an adjustment Shall be made in
                    computing the Basic Operating Cost for such year so that
                    Basic Operating Cost Shall be computed as though the
                    Building had been one hundred Percent (100%) occupied;
                    provided, however, that in no event shall Landlord be
                    entitled to collect in excess of one hundred percent (100%)
                    of the total Basic Operating Cost from all of the tenants in
                    the Building including Tenant. All costs and expenses shall
                    be determined in accordance with generally accepted
                    accounting principles which shall be consistently applied
                    (with accruals appropriate to Landlord's business). Basic
                    Operating Cost shall not include specific costs incurred for
                    the account of, separately billed to and Paid by specific
                    tenants.

                    (2) "Estimated Basic Operating Cost" for any particular year
                    shall mean Landlord's estimate of the Basic Operating Cost
                    for such fiscal year made prior to commencement of such
                    fiscal year as hereinafter provided. Landlord shall have
                    the right from time to time to revise its fiscal year and
                    interim accounting periods so long as the periods as so
                    revised are reconciled with prior periods in accordance with
                    generally accepted accounting principles applied in a
                    consistent manner.

                    (3) "Basic Operating Cost Adjustment" shall mean the
                    difference between Basic Operating Cost and Estimated Basic
                    Operating Cost for any fiscal year determined as hereinafter
                    provided.

                    (b) PAYMENT OF ESTIMATED BASIC OPERATING COST.

                        During Dec. of each fiscal year during the Term, or as
                    soon thereafter as practicable, Landlord shall give Tenant
                    written notice of the Estimated Basic Operating Cost for the
                    ensuing fiscal year. The Estimated Basic Operating Cost for
                    the fiscal year in which the Scheduled Term Commencement
                    Date falls is set forth in the Basic Lease Information
                    Sheet. Tenant shall pay Tenant's Proportionate Share of the
                    Estimated Basic Operating Costs with installments of Basic
                    Rent required to be paid pursuant to paragraph 3 above for
                    the fiscal year to which the estimate applies in monthly
                    installments on the first day of each calendar month during
                    such year, in advance. Such payment shall be construed to be
                    Rent for all purposes hereof. If at any time during the
                    course of a fiscal year, Landlord determines that Basic
                    Operating Cost will apparently vary from the then Estimated
                    Basic Operating Cost by more than five percent (5%),
                    Landlord may, by written notice to Tenant, revise the
                    Estimated Basic Operating Cost for the balance of such
                    fiscal year and Tenant shall pay Tenant's Proportionate
                    Share of the Estimated Basic Operating Cost as so revised
                    for the balance of the then current fiscal year on the first
                    day of each calendar month thereafter,
<PAGE>
 
                    such revised installment amounts to be Rent for all purposes
                    hereof.

                    (c) COMPUTATION OF BASIC OPERATING COST ADJUSTMENT.

                        Within one hundred twenty (120) days after the end of
                    each fiscal year as determined by Landlord or as soon
                    thereafter as practicable, Landlord shall deliver to Tenant
                    a statement of Basic Operating Cost for the fiscal year just
                    ended, accompanied by a computation of Basic Operating Cost
                    Adjustment. If such statement shows that Tenant's Payment
                    based upon Estimated Basic Operating Cost is less than
                    Tenant's Proportionate Share of Basic Operating Cost, then
                    Tenant shall pay the difference within twenty (20) days
                    after receipt of such statement. such payment to constitute
                    additional rent hereunder. If such statement shows that
                    Tenant's payments of Estimated Basic Operating Cost exceed
                    Tenant's Proportionate Share of Basic Operating Costs, then
                    (provided that Tenant is not in default under this Lease),
                    Tenant shall receive a credit for the amount of such payment
                    against Tenant's obligation for payment of Tenant's
                    Proportionate Share of Estimated Basic Operating Cost next
                    becoming due hereunder. If this Lease has been terminated or
                    the Term hereof has expired prior to the date of such
                    statement, then the Basic Operating Cost Adjustment shall be
                    paid by the appropriate party within twenty (20) days after
                    the date of delivery of the statement.

                    (d) NET LEASE.  This shall be a net lease and Base Rent
                    shall be paid to Landlord absolutely net of all costs and
                    expenses. The provisions for payment of Basic Operating Cost
                    by means of periodic payments of Tenant's Proportionate
                    Share of Estimated Basic Operating Cost and the Basic
                    Operating Cost Adjustment are intended to Pass on to Tenant
                    and reimburse Landlord for all cost and expenses of the
                    nature described in paragraph 29(a)(1) above incurred in
                    connection with ownership and operation of the Building and
                    such additional facilities now and in subsequent years as
                    may be determined by Landlord to be necessary to the
                    Building.

                    (e) TENANT AUDIT.  Tenant shall have the right at Tenant's
                    expense and upon not less than forty-eight (48)hours prior

                    Operating Cost Adjustment.  In the event that Tenant shall

                    Landlord the full amount in dispute, to cause Landlord's
                    books and records with respect to such fiscal year to be
                    audited by certified public accountants selected by Tenant
                    subject to Landlord's reasonable right of approval. The
                    Basic Operating Cost Adjustment shall be appropriately
                    adjusted on the basis of such audit. If such audit discloses

fully described in the Original Master Lease ("MASTER PREMISES").

          B.  The Original Master Lease, together with any amendments, are
collectively referred to as the Master Lease.

          C.  A copy of the Master Lease  is attached and incorporated in this
Sublease as Exhibit A.

                             SECTION 1.  SUBLEASE.

          Sublandlord subleases to Subtenant on the terms and conditions in this
Sublease the following portion of the Master Premises ("PREMISES"):

                      SECTION 2.  WARRANTY BY SUBLANDLORD.

          Sublandlord warrants to Subtenant that the Master Lease has not been
amended or modified except as expressly set forth in this Sublease; that
Sublandlord is not now, and as of the commencement of the Term (defined in this
Sublease) of this Sublease will not be, in default or breach of any of the
provisions of the Master Lease; and that Sublandlord has no knowledge of any
claim by Master Landlord that Sublandlord is in default or breach of any of the
provisions of the Master Lease.

                               SECTION 3.  TERM.

          The term of this Sublease will commence on the latter of November 3,
1997 ("COMMENCEMENT DATE"), or when Master Landlord consents to this Sublease
(if consent is required under the Master Lease), whichever occurs later, and end
on February 28, 2001 ("TERMINATION DATE") ("TERM"), unless terminated sooner in
accordance with the provisions of this Sublease.  If the Term commences on a
date other than the Commencement Date, Sublandlord and Subtenant will execute a
memorandum setting forth the actual date of commencement of the Term.

commencement of the Term.  If for any reason Sublandlord does not deliver
Possession to Subtenant on the Commencement of the Term, Sublandlord will not be
subject to any liability for this failure, the Termination Date will not be
extended by the delay, and the validity of this Sublease will not be impaired.
Rent will be abated until delivery of Possession.  However, if Sublandlord has
not delivered Possession to Subtenant within thirty (30) days after the
Commencement Date, at any time after that and before delivery of Possession,
Subtenant may give written notice to Sublandlord of Subtenant's intention to
cancel this Sublease.  The notice will set forth an effective date for the
cancellation, which will be at least ten (10) days after delivery of notice to
Sublandlord.  If Sublandlord delivers Possession to Subtenant on or before this
effective date, this Sublease will remain in full force.  If Sublandlord fails

Sublease will be canceled.  Upon cancellation, all consideration previously paid
by Subtenant to Sublandlord on account of this Sublease will be returned to
Subtenant, this Sublease will have no further force, and Sublandlord will have
no further liability to Subtenant because of this delay or cancellation.  If
Sublandlord permits Subtenant to take Possession prior to the commencement of
the Term, the early Possession will not advance the Termination Date and will be
subject to the provisions of this Sublease, including, without limitation, the
payment of rent.

                   SECTION 4.  RENT (AND OPERATING EXPENSES).

Subtenant's default or breach.  If Sublandlord uses any portion of the Security
Deposit, Subtenant will, within ten (10) days after written demand by

Sublease.  Sublandlord will not be required to keep the Security Deposit

interest in this Sublease, Sublandlord will deliver to its assignee as much of
the Security Deposit as Sublandlord then holds.  Within ten (10) days after the
Term has expired or Subtenant has vacated the Premises, whichever occurs last,
the Security Deposit, or as much as remains that has not been applied by
Sublandlord, will be returned to Subtenant or to the last assignee, if any, of
Subtenant's interest under this Sublease.

                          SECTION 6.  USE OF PREMISES.

          The Premises will be used and occupied only as permitted under the
Master Lease and for no other use or purpose.

                       SECTION 7.  CONDITION OF PREMISES.

          Subtenant accepts the Premises in their condition existing as of the
date of execution hereof.  Subtenant acknowledges that neither Sublandlord nor
its agents have made any representation or warranty as to suitability of the
premises for the conduct of Subtenant's business.

                     SECTION 8.  ASSIGNMENT AND SUBLETTING.

          Subtenant will not assign this Sublease or further sublet all or any
part of the Premises without the prior written consent of Sublandlord (and the
consent of Master Landlord, if this is required under the terms of the Master
Lease).

                   SECTION 9.  OTHER PROVISIONS OF SUBLEASE.

          All applicable terms and conditions of the Master Lease are
incorporated into and made a part of this Sublease as if Sublandlord were the
landlord, Subtenant the lessee, and the Premises the Master Premises, except for
the following: None.  As between Sublandlord and Subtenant, Subtenant agrees to
perform the lessee's obligations under the Master Lease during the Term to the
extent that these obligations are applicable to the Premises and this Sublease.
However, the obligation to pay rent and operating expenses to Master Landlord
under the Master Lease will be considered performed by Subtenant to the extent
and in the amount rent and operating expenses are paid to Sublandlord in
accordance with Section 4 of this Sublease.  Subtenant will not commit any act
or omission that will violate any of the provisions of the Master Lease.
Sublandlord will exercise due diligence in attempting to cause Master Landlord
to perform its obligations under the Master Lease for the benefit of Subtenant.
If the Master Lease terminates, at the option of Master Landlord, this Sublease
will terminate and the parties will be relieved of any further liability or
obligation under this Sublease.  However, if the Master Lease terminates as a
result of a default or breach by Sublandlord or Subtenant under this Sublease or
the Master Lease, the defaulting party will be liable to the nondefaulting party
for the damage suffered as a result of the termination.  Regardless, if the
Master Lease gives Master Landlord any right to terminate the Master Lease in
the event of the partial or total damage, destruction, or condemnation of the
Master Premises or the building or project of which the Master Premises are a
part, the exercise of this right by Master Landlord will not constitute a
default or breach by Sublandlord.

                          SECTION 10.  ATTORNEY FEES.

          If either party commences an action against the other in connection
with this Sublease, the prevailing party will be entitled to recover costs of
suit and reasonable attorney fees.

                          SECTION 11. NO BROKER FEES.

                                       2
<PAGE>
 
          There are no fees or commissions to be paid to any broker in
connection this transaction.  Sublandlord and Subtenant each warrant that they
have not dealt with any real estate broker in connection with this transaction.

                             SECTION 12.  NOTICES.

          All notices and demands that may be required or permitted by either
party to the other will be in writing.  All notices and demands by the
Sublandlord to Subtenant will be sent by United States Mail, postage prepaid,
addressed to the Subtenant at the Premises, and to the address in this Sublease
below, or to any other place that Subtenant may from time to time designate in a
notice to the Sublandlord.  All notices and demands by the Subtenant to
Sublandlord will be sent by United States Mail, postage prepaid, addressed to
the Sublandlord at the address in this Sublease, and to any other person or
place that the Sublandlord may from time to time designate in a notice to the
Subtenant.

                      SECTION 13.  SUCCESSORS AND ASSIGNS.

          This Sublease will be binding on and inure to the benefit of the
parties to it, their heirs, executors, administrators, successors in interest,
and assigns.

                            SECTION 14.  ATTORNMENT.

          If the Master Lease terminates, Subtenant will, if requested, attorn
to Master Landlord and recognize Master Landlord as Sublandlord under this
Sublease.

                              SECTION 15.  ENTRY.

          Sublandlord reserves the right to enter the Premises on reasonable
notice to Subtenant to inspect the Premises or the performance by Subtenant of
the terms and conditions of this Sublease.  In an emergency, no notice will be
required for entry.

                     SECTION 16.  LATE CHARGE AND INTEREST.

          The late payment of any Rent will cause Sublandlord to incur
additional costs, including the cost to maintain in full force the Master Lease,
administration and collection costs, and processing and accounting expenses.  If
Sublandlord has not received any installment of Rent within five (5) days after
that amount is due, Subtenant will pay five percent (5%) of the delinquent
amount, which is agreed to represent a reasonable estimate of the cost incurred
by Sublandlord.  In addition, all delinquent amounts will bear interest from the
date the amount was due until paid in full at a rate per annum ("APPLICABLE
INTEREST RATE") equal to the greater of (a) five percent (5%) per annum plus the
then federal discount rate on advances to member banks in effect at the Federal
Reserve Bank of San Francisco on the 25th day of the month preceding the date of
this Sublease or (b) ten percent (10%).  However, in no event will the
Applicable Interest Rate exceed the maximum interest rate permitted by law that
may be charged under these circumstances.  Sublandlord and Subtenant recognize
that the damage Sublandlord will suffer in the event of Subtenant's failure to
pay this amount is difficult to ascertain and that the late charge and interest
are the best estimate of the damage that Sublandlord will suffer.  If a late
charge becomes payable for any three (3) installments or Rent within any twelve
(12) month period, the Rent will automatically become payable quarterly in
advance.

                         SECTION 17.  ENTIRE AGREEMENT.

          This Sublease sets forth all the agreements between Sublandlord and
Subtenant concerning the Premises, and there are no other agreements either oral
or written other than as set forth in this Sublease.

                             SECTION 18.  GENERAL.

                                       3

          Time is of the essence in this Sublease. This Sublease will be
governed by and construed in accordance with California law.  THIS SUBLEASE WILL
HAVE NO EFFECT UNLESS CONSENTED TO BY MASTER LANDLORD WITHIN 15 DAYS AFTER
EXECUTION IF CONSENT IS REQUIRED UNDER THE TERMS OF THE MASTER LEASE.

                            SECTION 19.  INSURANCE.

          Without limiting Subtenant's other obligations under the Master Lease,
Subtenant agrees to purchase and maintain in force during the Term of this
Sublease all of the insurance, and in the amounts, as specified in Paragraph
11(e) of the Master Lease; provided, however, that Subtenant shall name both the
Master Landlord and Sublandlord as insureds under such policies.


          In Witness Whereof, the parties have executed this Sublease as of the
date first above written.

of the Master Lease or make any elections, exercise any right or remedy or give
any consent or approval under the Master Lease.  Sublandlord, with respect to

therewith, and Subtenant shall indemnify Sublandlord against, and hold

make any such payment to Master Landlord unless Master Landlord has provided a
three-day notice to pay such amount or forfeit the Master Lease.

this paragraph shall be credited toward the amounts payable by Subtenant to
Sublandlord under the Sublease. In the event Subtenant tenders payment directly

reduce Subtenant's obligations hereunder, Sublandlord shall cooperate with
Subtenant to enforce all such warranties and indemnities.

          ------

use reasonable efforts to cause each applicable insurance policy it obtains to
provide that the insurer thereunder waives all right of recovery by way of
subrogation as required herein in connection with any damage covered by the
policy.

     14.  Effect of Addendum.  All terms with initial capital letters used
          ------------------

          1.3  Bill of Sale Upon Payment In Full of Purchase Price; Vesting of
               ---------------------------------------------------------------
Title.
- -----

Within five (5) business days of Seller's receipt of payment in full for the
Purchase Price, Seller shall execute and deliver to Buyer a Bill of Sale for the
Purchase Assets (the "Closing").  Upon execution and delivery to Buyer of the
Bill of Sale and subject to the terms and conditions of this Agreement, Buyer
will be vested with title to all of the Purchase Assets, free and clear of all
liens, mortgages, security interests, pledges, encumbrances and charges.
Notwithstanding anything herein to the contrary, to the extent the
phone/voicemail system making up part of the Purchase Assets ("Phone System")
contains or is made up of software, which software may be covered by license
from the Phone System manufacturer, Seller does not own title to such software
or intellectual property rights in and to any such software, nor is Seller
assigning ownership of such software of any intellectual property rights therein
to Buyer.  Instead, the license to use any such software as part of the Phone
System, not the software itself, is being assigned to Buyer hereunder as part of
the purchase of the Phone System.

          1.4  Limited Right To Rescind.  Notwithstanding anything to the 
               ------------------------                        
contrary herein, the effective date (the "Effective Date") of this Agreement
shall be the earliest date by which all of the following have occurred: (i) the
Sublease has been executed by Buyer and Seller, and (ii) the Master Landlord (as
defined therein) has consented to the Sublease. This Agreement shall be
conditioned upon, and shall be of no force or effect until, the occurrence of
the Effective Date. If the Effective Date does not occur, for any reason
whatsoever, on or before November 30, 1997, each party shall have the right to
rescind this Agreement by giving written notice to the other party after
November 30, 1997 but prior to the Effective Date, in which event this Agreement
shall be null and void and of no legal force or effect whatsoever.

          2.   PURCHASE PRICE AND PAYMENT.
               ---------------------------

               2.1  Price and Payment Schedule.  The purchase price for the 
                    --------------------------

Payment Date and the last payment due no later than on the date 40 months
thereafter ("Final Due Date").

               2.2  Right To Prepay.  At no penalty to Buyer and with no 
                    ---------------          
decrease or deduction to the total Purchase Price amount, Buyer may at any time
prior to Final Due Date, upon at least five (5) days prior written notice to
Seller, pay in full the remaining amount of the Purchase Price.

               2.3  Payments and Late Payments.  All payments hereunder shall 
                    --------------------------        
be made by check to Seller at Seller's address set forth below, or by wire
transfer to Seller's bank account(s), such bank account information to be
provided to Buyer by Seller. Any and all late payments hereunder will be subject
to a late payment charge from the date the amount was due until paid in full at
a rate per annum ("Applicable Interest Rate") equal to the greater of (a) five
percent (5%) per annum plus the then federal discount rate on advances to member
banks in effect at the Federal Reserve Bank of San Francisco on the 25th day of
the month preceding the date of this Agreement, or (b) ten percent (10%).
However, in no event will the Applicable Interest Rate exceed the maximum

           -----------------------------------                                 
tax returns and reports as required by law. The provision for taxes of the
Company as shown in the Financial Statements is adequate for taxes due or

franchises, permits, licenses and any similar authority as necessary for the
conduct of its business as now being conducted by it, the lack of which could
materially and adversely affect (financially or otherwise) the business,
properties, assets, liabilities or prospects (as contemplated in the Business
Plan) of the Company and believes it can obtain, without undue burden or
expense, any similar authority for the conduct of its business as planned to be
conducted (as contemplated in the Business Plan). The Company is not in default
in any material respect under any of such franchises, permits, licenses or other
similar authority.

                                   SECTION 4

               Representations and Warranties of the Purchasers
               ------------------------------------------------

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

     4.1   Experience. Purchaser has substantial experience in evaluating and
           ----------                                                         
investing in private placement transactions so that Purchaser is capable of
evaluating the merits and risks of Purchaser's investment in the Company.
Purchaser, by reason of its business or financial experience or the business or
financial experience of its professional advisors who are unaffiliated with and
who are not compensated by the Company or any affiliate or selling agent of the
Company, directly or indirectly, has the capacity to protect its own interests
in connection with the purchase of the Shares under this Agreement.

     4.2   Investment. Purchaser is acquiring the Shares and the underlying
           ----------                                                       
Common Stock for investment for Purchaser's own account, not as a nominee or
agent, and not with the view to, or for resale in connection with, any
distribution thereof Purchaser understands that the Shares and the underlying
Common Stock have not been, and will not be, registered under the Securities Act
by reason of a specific exemption therefrom, and that any such exemption would
depend, among other things, upon the bona fide nature of the investment intent
and the accuracy of such Purchaser's representations as expressed in this
Agreement. Purchaser has not been formed for the specific purpose of acquiring
the Shares or the underlying Common Stock.

     4.3   Rule 144. Purchaser acknowledges that the Shares and the underlying
           --------                                                            
Common Stock must be held indefinitely unless subsequently registered under the
Securities Act or an exemption from such registration is available. Purchaser
is aware of the provisions of Rule 144 promulgated under the Securities Act
which permit limited resale of shares purchased in a private placement subject
to the satisfaction of certain conditions, including, among other things, the
existence of a public market for the shares, the availability of certain current
public information about the Company, the resale occurring not less than two
years after a party has purchased and paid for the security to be sold, the sale
being effected through a "broker's transaction" or in transactions directly with
a "market maker" (as provided by Rule 144(f)) and the number of shares being
sold during any three-month period not exceeding specified limitations.

     4.4   No Public Market. Purchaser understands that no public market now
           ----------------                                                  
exists for any of the securities issued by the Company, that the Company has
made no assurances that a public market will ever exist for the Shares or the
underlying Common Stock and that, even if such a public market exists at some
future time, the Company may not then be satisfying the current public
information requirements of Rule 144.

     4.5   Access to Data. Purchaser and its representatives have met with
           --------------                                                  
representatives of the Company and thereby have had the opportunity to ask
questions of, and receive answers from, said representatives concerning the
Company and the terms and conditions of this transaction as well as to

                                      -10-
<PAGE>
 
obtain any information requested by Purchaser. Any questions raised by Purchaser
or its representatives concerning the transaction have been answered to the
satisfaction of Purchaser and its representatives. Purchaser's decision to
purchase the Shares is based in part on the answers to such questions as
Purchaser and its representatives have raised concerning the transaction and on
its own evaluation of the risks and merits of the purchase and the Company's
proposed business activities.

     4.6   Authorization. This Agreement when executed and delivered by the
           -------------                                                    
Purchaser will constitute a valid and legally binding obligation of the
Purchaser, enforceable in accordance with its terms subject to bankruptcy,
insolvency, fraudulent conveyance, moratorium or other laws affecting creditors
rights generally and to equitable principles of general applicability.

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

     The Company hereby covenants and agrees as follows:

     7.1   Financial Information. The Company will mail the following reports to
           ---------------------
each Purchaser for so long as such Purchaser is a holder of any Shares purchased
by such person pursuant to this Agreement (or Common Stock issued upon
conversion of the Shares):

           (a) As soon as practicable after the end of each fiscal year, and in
any event within ninety (90) days thereafter, consolidated balance sheets of the
Company and its subsidiaries, if any, as of the end of such fiscal year, and
consolidated statements of income and consolidated statements of changes in
financial position of the Company and its subsidiaries, if any, for such year,
prepared in accordance with generally accepted accounting principles and setting
forth in each case in comparative form the figures for the previous fiscal year,
all in reasonable detail and audited by the Company's independent public
accountants.

           (b) Contemporaneously with delivery to holders of Common Stock, a
copy of each report of the Company delivered to holders of the Company's Common
Stock.

     7.2   Additional Information.  For so long as Purchaser holds not less
           ----------------------

or Common Stock issued upon conversion of the Shares), as adjusted for
recapitalizations, stock splits, stock dividends and the like, the Company will
mail the following reports to such Purchaser:

           (a) As soon as practicable after the end of the first, second and
third quarterly accounting periods in each fiscal year of the Company and in any
event within 45 days thereafter, a 

                                      -13-
<PAGE>
 
consolidated balance sheet of the Company and its subsidiaries, if any, as of
the end of each such quarterly period, and consolidated statements of income and
consolidated statement of cash flows of the Company and its subsidiaries for
such period, and for the accepted accounting principles, all in reasonable
detail and signed, subject to charges resulting from year-end audit adjustments,
by the principal financial or accounting officer of the Company.

           (b) As soon as practicable, but in any event prior to the end of each
fiscal year, a budget for the next fiscal year, including balance sheets and
sources and applications of funds statements and, as soon as prepared, any other
budgets or revised budgets prepared by the Company.

           (c) For so long as a Purchaser is eligible to receive reports under
this Section 7.2, it shall also have the right, at its expense, to discuss the
affairs, finances and accounts of the Company with the Company's officers, all
at such reasonable times and as often as may be reasonably requested; provided,
however, that the Company shall not be obligated to provide any information that
it reasonably considers to be a trade secret or to contain confidential
information.

transferred to a holder of, or affiliated holders who in the aggregate hold, at
least 255,000 Shares (or an equivalent number of shares consisting of the Shares

Section 7.3 would materially adversely affect its proprietary position, such
information may be edited in the manner necessary to avoid such effect.

to Section  25102(f) of the California Corporations Code.

ST will provide its customers with a complete cut characterization environment
and data, based on Eldo simulations, so as to alleviate the inaccuracies due to
the curve-fitting process encountered for previous HCMOS5 generators.

The list of representative cuts for characterization will be agreed between ST
and VLI. The number of cuts will be similar to the number used for HCMOS6
generators.

1.3.1  ELDO NETLISTS AND STIMULI FOR CHARACTERIZATION CUTS.
VLI will provide these to ST

1.3.2  RDB, EQN DATA IN BC, TYP, WC

For all the above ELDO netlists and stimuli, these will be run in best
conditions, typical conditions, and worst case conditions.  The results of these
runs will be provided to ST. QA for these data will be performed by VLI, and
checked by ST, according to a methodology agreed upon between VLI and ST.

1.3.3  CADENCE SCHEMATICS FOR MEMORY LEAF-CELLS AND HIERARCHY LEVELS

VLI will provide Cadence schematics for all the memory leaf cells and hierarchy
levels. These schematics will use ST's components, to be compatible with ST's
proprietary Generator Characterization System.

For each leaf-cell there are 2 or 3 schematics, as follows:

*    The actual cell components schematics.

*    The cell schematics + parasitic elements for critical path simulation.

*    An optional simplified cell schematics to be used as loading for critical
     path simulation.

ST will provide to VLI the Cadence libraries necessary to enter these
schematics, a.k.a. "HCMOS7 design kit", as well as ST's netlister for
these library components ("SEP").

1.3.4  CRITICAL PATH GENERATORS IN ST'S PROPRIETARY ENVIRONMENT
VLI will support ST engineers on VLI premises to allow a complete know-how
acquisition by ST

1.3.5  CRITICAL PATH ELDO STIMULI GENERATOR
VLI and ST will each use their own tools for generating the Eldo stimuli for the
critical path Generator.

1.4    BACK-END

1.4.1  LAYOUT GENERATORS
VLI will be in charge of the layout generators development, as it was for
HCMOS6. Moreover, VLI will be in charge of their integration into the
UNIGEN environment.

After that, VLI will also validate the integrated back-end generators into the
corresponding validation flow.

1.4.2  ABSTRACT GENERATOR
ST will develop the abstract generator for Cell3 and Block-Ensemble for all
memories.  ST will add the post-processing routines to bring all pins to the
Cell3 grid.

1.4.3  POWER DISTRIBUTION
VLI will develop the layout generators without power-rings.  The number of Vdd
and Gnd connections will be limited to one or two of each.  Metal3 will be used
for distributing power and ground internally to the memories.  Metal3 will also
be used to shield sensitive nodes from potentially noisy Metal4 lines running
above the memories.

1.4.4  SOG EMBEDDABILITY
ST will develop the routines to make the memories layout SOG-compatible.

1.4.5 SPICE NETLIST GENERATOR FOR LVS
VLI will develop a spice netlist generator for Dracula/LVS. A solution not using
the Cadence netlister will be provided: Either Skill-based or C-based
(preferred).

1.5  SILICON VALIDATION
VLI is fully responsible for this phase, including actions that may be done by
ST, such as processing or testing.  In case of problems, VLI should escalate the
issue within ST to insure prompt resolution.

1.5.1  SILICON VALIDATION PLAN
VLI is responsible for the definition and implementation of the silicon
validation plan.  VLI will generate the necessary generator cuts.
VLI will describe in the plan how to fully characterize the memory generator
cuts.

1.5.2  TEST CHIPS DESIGN AND FAB
ST will provide the layout of cavities in which the test cuts will be inserted.
VLI will complete the layout of the test cavities with the layout of the test
cuts and with the connections between them and the IO PADS.
ST will provide manpower to assemble the layout of the test cavities into test

franchises, permits, licenses and any similar authority as necessary for the

           -------------------                                                 
Incorporation and Bylaws are in the form previously provided to the Purchasers.

                                   SECTION 4

                Representations and Warranties of the Purchasers
                ------------------------------------------------

      Each Purchaser hereby represents and warrants to the Company with respect
to the purchase of the Shares and, with respect to Synopsys, the Warrant, as
follows:

      4.1 Experience.  Purchaser has substantial experience in evaluating and
          ----------                                                         
investing in private placement transactions so that Purchaser is capable of
evaluating the merits and risks of Purchaser's investment in the Company.
Purchaser, by reason of its business or financial experience or the business or
financial experience of its professional advisors who are unaffiliated with and
who are not compensated by the Company or any affiliate or selling agent of the
Company, directly or indirectly, has the capacity to protect its own interests
in connection with the purchase of the Shares and the Warrant under this
Agreement.

      4.2 Investment.  Purchaser is acquiring the Shares and the underlying
          ----------                                                       
Common Stock, and, with respect to Synopsys, the Warrant and the Warrant Shares
and the Common Stock issuable upon conversion of the Warrant Shares for
investment for Purchaser's own account, not as a nominee or agent, and not with
the view to, or for resale in connection with, any distribution thereof.
Purchaser understands that the Shares and the underlying Common Stock and, with
respect to Synopsys, the Warrant and the Warrant Shares and the shares of Common
Stock issuable upon conversion of the Warrant Shares have not been, and will not
be, registered under the Securities Act by reason of a specific exemption
therefrom, and that any such exemption would depend, among other things, upon
the bona fide nature of the investment intent and the accuracy of such
Purchaser's representations as expressed in this Agreement. Purchaser has not
been formed for the specific purpose of acquiring the Shares or the underlying
Common Stock or, with respect to Synopsys, the Warrant and the Warrant Shares
and the shares of Common Stock issuable upon conversion of the Warrant Shares.

      4.3 Rule 144.  Purchaser acknowledges that the Shares and the underlying
          --------                                                            
Common Stock and, with respect to Synopsys, the Warrant and the Warrant Shares
and the shares of Common Stock issuable upon conversion of the Warrant Shares
must be held indefinitely unless subsequently registered under the Securities
Act or an exemption from such registration is available.  Purchaser is aware of
the provisions of Rule 144 promulgated under the Securities Act which permit
limited resale of shares purchased in a private placement subject to the
satisfaction of certain conditions, including, among other 

                                      -9-
<PAGE>
 
things, the existence of a public market for the shares, the availability of
certain current public information about the Company, the resale occurring not
less than two years after a party has purchased and paid for the security to be
sold, the sale being effected through a "broker's transaction" or in
transactions directly with a "market maker" (as provided by Rule 144(f)) and the
number of shares being sold during any three-month period not exceeding
specified limitations.

      4.4 No Public Market.  Purchaser understands that no public market now
          ----------------                                                  
exists for any of the securities issued by the Company, that the Company has
made no assurances that a public market will ever exist for the Shares or the
underlying Common Stock or the Warrant Shares or the shares of Common Stock
issuable upon conversion of the Warrant Shares and that, even if such a public
market exists at some future time, the Company may not then be satisfying the
current public information requirements of Rule 144.

      4.5 Access to Data.  Purchaser and its representatives have met with
          --------------                                                  
representatives of the Company and thereby have had the opportunity to ask
questions of, and receive answers from, said representatives concerning the
Company and the terms and conditions of this transaction as well as to obtain
any information requested by Purchaser.  Any questions raised by Purchaser or
its representatives concerning the transaction have been answered to the
satisfaction of Purchaser and its representatives. Purchaser's decision to
purchase the Shares (and Synopsys' decision to purchase the Warrant) is based in
part on the answers to such questions as such Purchaser and its representatives
have raised concerning the transaction and on its own evaluation of the risks
and merits of the purchase and the Company's proposed business activities.

      4.6 Authorization.  This Agreement when executed and delivered by the
          -------------                                                    
Purchaser will constitute a valid and legally binding obligation of the
Purchaser, enforceable in accordance with its terms subject to bankruptcy,
insolvency, fraudulent conveyance, moratorium or other laws affecting creditors
rights generally and to equitable principles of general applicability.

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

                      Conditions to Closing of Purchasers

warranties made by the Company in Section  3 of this Agreement shall be true and

each Purchaser for so long as such Purchaser is a holder of any Shares or
Warrant Shares purchased by such person pursuant to this Agreement (or Common or
Preferred Stock issued upon conversion of the Shares or Warrant Shares):

                                      -12-
<PAGE>
 
          (a) As soon as practicable after the end of each fiscal year, and in
any event within ninety (90) days thereafter, consolidated balance sheets of the
Company and its subsidiaries, if any, as of the end of such fiscal year, and
consolidated statements of income and consolidated statements of changes in
financial position of the Company and its subsidiaries, if any, for such year,

accountants.

          (b) Contemporaneously with delivery to holders of Common Stock, a copy
of each report of the Company delivered to holders of the Company's Common
Stock.

      7.2 Additional Information.    For so long as Purchaser holds not less
          ----------------------                                            
than 255,000 Shares (or an equivalent number of shares consisting of the shares
of Common Stock issued upon conversion of the Shares or Warrant Shares or Common
or Preferred Stock issued upon conversion of the Warrant Shares), as adjusted
for recapitalizations, stock splits, stock dividends and the like, the Company
will mail the following reports to such Purchaser:

          (a) As soon as practicable after the end of the first, second and

event within 45 days thereafter, a consolidated balance sheet of the Company and
its subsidiaries, if any, as of the end of each such quarterly period, and
consolidated statements of income and consolidated statement of cash flows of
the Company and its subsidiaries for such period, and for the accepted

          (b) As soon as practicable, but in any event prior to the end of each

          (c) For so long as a Purchaser is eligible to receive reports under
this Section 7.2, it shall also have the right, at its expense, to discuss the
affairs, finances and accounts of the Company with the Company's officers, all
at such reasonable times and as often as may be reasonably requested; provided,
however, that the Company shall not be obligated to provide any information that
it reasonably considers to be a trade secret or to contain confidential
information.

      7.3 Transfer of Information Rights.  The information rights set forth in
          ------------------------------                                      
Sections 7.1 and 7.2 may be transferred in any nonpublic transfer of Shares or
Warrant Shares (or Shares of Common or Preferred Stock issued upon conversion of
the Shares or Warrant Shares), provided that the Company is given written notice
of such transfer, and provided further that the right to receive the information
set forth in Section 7.2 may only be transferred to a holder of, or affiliated
holders who in the aggregate hold, at least 255,000 Shares or Warrant Shares (or
an equivalent number of shares consisting of the Shares, Warrant Shares or
Common or Preferred Stock issued upon conversion of the Shares or Warrant
Shares, as appropriately adjusted for stock splits and the like).   In the event
that the Company reasonably determines that provision of information to a
transferee pursuant to this Section 7.3 would materially 

                                      -13-

7.2 shall terminate and be of no further force or effect upon the earlier of (i)
the consummation of the Company's sale of its Common Stock in an underwritten
public offering pursuant to an effective registration statement filed under the
Securities Act, immediately subsequent to which the Company shall be obligated
to file annual and quarterly reports with the Commission pursuant to Section 13
or 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act") or (ii) the
registration by the Company of a class of its equity securities under Section
12(b) or 12(g) of the Exchange Act.

      7.5 Securities Laws Compliance.  The Company shall within fifteen days of
          --------------------------

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

                                                -----------        

      7.7 Share Repurchases.  The Company covenants that at any time it conducts
          -----------------                                                     
a repurchase of shares of the Company's stock held by any of the Company's
shareholders, and such repurchase would cause Synopsys' ownership interest in
the Company to increase to an amount in excess of 9.9% of the Company's then
outstanding capital stock, the Company shall repurchase shares of the Company's
stock held by Synopsys on a pro rata basis to the extent necessary to prevent
Synopsys' ownership interest in the Company from increasing to an amount in
excess of 9.9% of the Company's then outstanding capital stock.  This covenant
shall terminate and be of no further force or effect upon the earlier of (i) the
consummation of the Company's sale of its Common Stock in an underwritten public
offering pursuant to an effective registration statement filed under the
Securities Act and (ii) the closing of a merger or acquisition in which the
shareholders of the Company prior to such event own less than a majority of the
securities of the Company following such event.

initiated by Licensee's written purchase orders sent to Artisan Components and
requesting a delivery date during the term of this Agreement. All Licensed
Products provided to Licensee by Artisan Components during the term of this
Agreement will be subject to the terms and conditions of this Agreement. Except
as otherwise agreed in writing signed by an officer of Artisan Components,
nothing contained in any purchase order submitted by Licensee pursuant to this
Agreement will in any way modify, delete or add any terms or conditions to said
purchases and licenses, and Licensee hereby waives such purchase order
provisions.

     5.2  Changes to the scope of work either requested by and/or necessitated
by Licensee's specifications will be evaluated for both schedule and cost
impact. The Licensee will be asked to complete an Engineering Change Order
Request Form, an "ECO," and submit it to Artisan Components for review. If after
review by Artisan Components, it is determined that both the schedule and/or
quoted sales prices must change to accommodate the ECO, Artisan Components will
notify the Licensee in writing on our ECO Response Form of any such schedule
and/or price changes. Licensee must provide written acceptance or refusal of the
new schedule and/or costs within five (5) days of having been so notified.
Failure to do so will cause Artisan Components to proceed with the project as if
the Licensee's ECO Request Form had never been received. Sample ECO Request and
ECO Response Forms are attached as Exhibits A and B.

                                                                               4

taxes (including without limitation sales, use, excise, and value added taxes)

Components to establish that such taxes have been paid.

payable to Artisan Components under this Agreement, Licensee shall keep complete
and accurate books and records.  These records shall be retained for a period of
twelve (12) months from the date of payment, notwithstanding the expiration or
termination of this Agreement. Licensee agrees to permit its books, records to
be examined by Artisan Components or its designee, subject to reasonable
confidentiality provisions, [*** Redacted] during normal business hours, to
verify the accuracy of the License Fees, royalties and other amounts paid to
Artisan Components under this Agreement. Prompt adjustment shall be made by
Licensee corresponding to the net amount of any underpayment of any and all

an examination reveals an underpayment of more than [*** Redacted], then
Licensee shall promptly reimburse Artisan Components for the cost of such
examination.
 
     7.9  If any currency conversion shall be required in connection with the
calculation of amounts payable under this Agreement, such conversion shall be
made using the selling exchange rate for

or its distributors or customers use the Licensed Products for such
applications.  Licensee shall notify each distributor and customer of Licensee
of such limitation of use of the Licensed Products and Licensed Integrated

  22.  NDA

  22.1  Each party (i.e., Artisan Components or Licensee, the "Receiving Party")
understands that the other party (the "Disclosing Party") has disclosed or may
disclose tangible information designated as "Confidential" or "Proprietary",
relating to this Agreement (hereinafter "Proprietary Information"). For a period
of four (4) years from the date upon which the receiving party first receives
the Proprietary Information from the Disclosing Party and, except to the extent
otherwise provided for under this Agreement, the Receiving Party agrees (i) to
hold the Disclosing Party's Proprietary Information in confidence as a fiduciary
and to take precautions to protect such Proprietary Information  (including,
without limitation, those precautions the Receiving Party employs with respect
to its confidential materials of similar type), and (ii) not to divulge any such
Proprietary Information or any information derived therefrom to any third party.
 
  22.2  Notwithstanding the above, all information which is disclosed in
intangible form by the Disclosing Party for the purpose of this Agreement and
which is identified by the Disclosing Party as

                                                                              12
<PAGE>

"confidential" or "proprietary" shall be deemed to be Proprietary Information
for purposes of this Agreement for a period of sixty (60) days from the date of
disclosure thereof, provided, however, that if the Receiving Party receives from
the Disclosing Party within such sixty-day period a written document summarizing
such information and designating such information as "Confidential" or
Proprietary", such information shall be deemed to be Proprietary Information for
purposes of this Agreement for a period of four (4) years from the disclosure
thereof.

  22.3  Without  granting any right or license, the Disclosing Party agrees that
the foregoing shall not apply with respect to any information that (i) is in the
public domain at the time of disclosure or thereafter enters the public domain,
through no improper action or inaction by the Receiving Party  or any of its
affiliates, agents or employees, or (ii) was in its possession or known by it
prior to receipt from the Disclosing Party, or (iii) was rightfully disclosed to
it by any third party, provided, however, that the Receiving Party complies with
any restrictions imposed by such third party, or (iv) was developed by employees
of the Receiving Party who did not have access to the Proprietary Information.

  22.4  Due to the unique nature of the Disclosing Party's Proprietary
Information hereunder and the competitive advantage they give the parties, there
can be no adequate remedy at law for any breach of each party's obligations
under this Section and upon any such breach or any threat thereof, the non-
breaching party shall be  entitled to appropriate equitable relief in addition
to whatever other remedies it might be entitled. The provisions of this Section
shall survive the expiration or other termination of this Agreement.

  23. MISCELLANEOUS TERMS

  23.1  The relationship of the parties hereto is that of independent
contractors, and neither party is an employee, agent, partner or joint venturer
of the other.

  23.2  Except for payments due hereunder by Licensee, neither party shall have
liability for its failure to perform its obligations hereunder when due to
circumstances beyond its reasonable control.

  23.3  Artisan represents that it has the capabilities and resources to perform
the work required under this agreement according to the mutually agreed
specifications and delivery schedule.  Artisan  shall perform the development
work covered by this agreement in a professional and workmanlike manner
according to standards practiced by Silicon Valley's leading semiconductor
design firms.

      4.  Lease Term.
          ---------- 

          A.   Term.  The Term of this Lease shall be seven (7) years,
               ----                                                   
commencing on the Commencement Date and expiring seven (7) years thereafter,
unless sooner terminated and subject to any extension granted hereunder.  The
Commencement Date of this Lease shall be the earliest occurring of the
following:

               (i)   The date a Notice of Completion for the Exterior ADA Work,
the Seismic Work and the Tenant Improvements to be constructed or installed by
Tenant pursuant to EXHIBIT B is filed by Tenant's contractor; or
                   ---------                                    

               (ii)  The date the City of Sunnyvale has approved the Exterior
ADA Work, the Seismic Work and the Tenant Improvements constructed pursuant to
EXHIBIT B in accordance with its building code, evidenced by its completion of a
- ---------                                                                       
final inspection and written approval of such improvements as so completed in
accordance with the building permit issued for such work; or

               (iii) The date Tenant commences occupancy of the Premises and
commences operation of its business in the Premises.

When the actual Commencement Date is determined, the parties shall execute a
Commencement Date Memorandum setting forth such date in the form shown in
EXHIBIT C.
- --------- 

          B.   Tenant Delays.  If the Commencement Date has not occurred within
               -------------                                                   
seventy-five (75) days after the date this Lease has been fully executed, then,
beginning on the seventy-sixth (76th) day and continuing on the first day of
each calendar month thereafter until the Commencement Date, Tenant shall pay to
Landlord the Monthly Rent set forth in Paragraph 5.A. Notwithstanding the
foregoing, if the Exterior ADA Work, the Seismic Work and the Tenant
Improvements are not substantially completed within such 75-day period due to no
fault of Tenant (as defined below), then, in lieu of the Monthly Rent and
Additional Rent due pursuant to Paragraphs 5.A. and 5.B., Tenant shall pay to
Landlord monthly, as Monthly Rent, Landlord's actual out-of-pocket costs
incurred in connection with the ownership and operation of the Premises during
such period, which shall include insurance premiums, Real Property Taxes,
principal and interest due under any mortgage or deed of trust recorded against
the Premises, and any charges due under any on-going maintenance, repair or
service contracts for the Premises, which out-of-pocket costs shall not exceed a
total amount of $20,000.00 per month.  Such payments by Tenant shall be due
beginning on the seventy-sixth (76th) day and continuing on the first day of
each calendar month thereafter until the Commencement Date.  In no event,
however, will the Commencement Date occur later than October 1, 1997 unless
delays in completion of the Tenant Improvements and the Seismic Work are due to
Landlord's failure to timely approve the Tenant Improvement Plans, and/or the
Seismic Plans or Landlord's failure to pay when due the cost of the Exterior ADA
Work or the Seismic Work as provided in EXHIBIT B.  For purposes of this Lease,
                                        ---------                              
the term "due to the fault of Tenant" shall mean: (i) Tenant's election to use
special materials, finishes or installations which are not readily available;
(ii) Tenant's failure to submit any plans in accordance with time frames
specified in EXHIBIT B; (iii) any changes to the Tenant Improvement Plans and/or
             ---------                                                          
the Seismic Plans after their approval by Landlord, where such changes are made
by Tenant at its election, and

                                      -3-
<PAGE>
 
not required by Landlord or any governmental authority; and (iv) Tenant's
failure to make timely payment of any amounts due to Tenant's architect and/or
general contractor in connection with the Tenant Improvements.

          C.   Early Entry.  Tenant shall be permitted to enter the Premises
               -----------                                                  
upon execution of this Lease for the purpose of demolishing and/or removing the
existing interior improvements in the Building, completing the seismic
improvements approved by Landlord, constructing the Tenant Improvements,
installing Tenant's equipment and furniture, and otherwise preparing the
Premises for Tenant's occupancy.  Such early entry shall be at Tenant's sole
risk and subject to all the terms and provisions hereof, except for the payment
of Rent which, subject to the provisions of Paragraph 4.B.,  shall commence on
the Commencement Date.  Tenant shall, however, pay when due any utility charges
incurred during such early entry period.  Prior to such early entry, Tenant
shall deliver to Landlord a certificate of insurance satisfying the requirements
set forth in Paragraphs 21.B.(i) and 21.F.  Landlord shall have the right to
impose such additional reasonable conditions on Tenant's early entry as Landlord
shall deem appropriate.

          D.   Delay in Delivery of Possession.  Upon execution of this Lease by
               -------------------------------                                  
Landlord and Tenant, payment by Tenant of the Security Deposit and the Monthly
Rent due for the first month of the Term, and delivery to Landlord of Tenant's
insurance certificate (collectively, the "Execution Date"), Landlord shall
deliver possession of the Premises to Tenant.  Notwithstanding anything to the
contrary in this Lease, if Landlord fails to deliver possession of the Premises
to Tenant on the Execution Date, the Commencement Date and Tenant's obligation
to pay Rent or Landlord's out-of-pocket costs incurred in connection with the
ownership and operation of the Premises shall be delayed by one day for each day
that Landlord fails to deliver possession of the Premises to Tenant. For example
if Landlord fails to deliver possession of the Premises to Tenant for five (5)
days after the Execution Date, then the Commencement Date, and Tenant's
obligation to pay Rent or Landlord's out-of-pocket costs, shall be five (5) days
after the date described in Paragraph 4.A. or 4.B. of the Lease, as applicable.
In addition, if Landlord fails to deliver possession of the Premises to Tenant
within thirty (30) days after the Execution Date, then in addition to Tenant's
other rights or remedies, Tenant may terminate this Lease by written notice to
Landlord, and in such event Landlord shall promptly refund to Tenant all monies
previously paid by Tenant to Landlord.

      5.  Rent.
          ---- 

          A.   Monthly Rent.  Tenant shall pay to Landlord, in lawful money of
               ------------                                                   
the United States, for each calendar month of the  Term, net Monthly Rent in
accordance with the following schedule, in advance, on the first day of each
calendar month and, except as otherwise expressly permitted in this Lease,
without abatement, deduction, claim, offset, prior notice or demand, except that
the net Monthly Rent due for the first month of the Term shall be paid upon
Lease execution.

        Months of Term                  Net Monthly Rent
        --------------                  ----------------

         1 through 12                   $35,926.00/month
        13 through 24                   $37,559.00/month
        25 through 36                   $39,192.00/month
        37 through 48                   $40,825.00/month
        49 through 60                   $42,458.00/month
        61 through 72                   $44,091.00/month
        73 through 84                   $45,724.00/month

Additionally, Tenant shall pay, as and with the net Monthly Rent, the monthly 
Real Property Taxes as set forth in paragraph 15.

        B.   Additional Rent. All monies required to be paid by Tenant under 
             ---------------
this Lease, including Real Property Taxes pursuant to Paragraph 15, and 
insurance premiums pursuant to Paragraph 21, fee shall be deemed Additional 
Rent.

        C.   Prorations. If the Commencement Date is not the first (1st) day of 
             ----------
a month, or if the termination date of this Lease is not the last day of a 
month, a prorated installment of Rent based on a thirty (30) day month shall be 
paid for the fractional month during which the Lease commences or terminates.

     6. Late Payment Charges.
        --------------------

        Tenant acknowledges that late payment by Tenant to Landlord of Rent and
other charges provided for under this Lease will cause Landlord to incur costs
not contemplated by this Lease, the exact amount of such costs being extremely
difficult or impracticable to fix. Therefore, if any installment of Rent or any
other charge due from Tenant is not received by Landlord when due, and such Rent
or other charge remains unpaid for more than five (5) days after such amount is
due, Tenant shall pay to Landlord an additional sum equal to four percent (4%)
of the amount overdue as a late charge. The parties agree that this late charge
represents a fair and reasonable estimate of the costs that Landlord will incur
by reason of the late payment by Tenant. In addition, if any Rent or other sum
due hereunder is not paid by Tenant within thirty (30) days after the date such
Rent or other payment is due, then Tenant shall pay interest on the amount due
at the Interest Rate from the date such Rent or other sum was due until paid.

     7. Security Deposit.
        ----------------

        Tenant shall deposit with Landlord upon execution the sum of Forty-Five
Thousand Seven Hundred Twenty-Four and no/100th Dollars ($45,724.00) as the
Security Deposit for the full

                                      -5-

and faithful performance of every provision of this Lease to be performed by
Tenant. If Tenant defaults with respect to any provision of this Lease, Landlord
may apply all or any part of the Security Deposit for the payment of any rent or
other sum in default, the repair of any damage to the Premises caused by Tenant
or the payment of any other amount which Landlord may spend or become obligated
to spend by reason of Tenant's default or to compensate Landlord for any other
loss or damage which Landlord may suffer by reason of Tenant's default to the
full extent permitted by law. Tenant hereby waives any restriction on the use or
application of the Deposit by Landlord as set forth in California Civil Code
Section 1950.7. If any portion of the Security Deposit is so applied, Tenant
shall, within ten (10) days after written demand therefor, deposit cash with
Landlord in an amount sufficient to restore the Security Deposit to its original
amount. Landlord shall not be required to keep the Security Deposit separate
from its general funds, and Tenant shall not be entitled to interest on the
Security Deposit. If Tenant is not otherwise in default, the Security Deposit or
any balance thereof shall be returned to Tenant within thirty (30) days of
termination of the Lease. In the event of any termination of Landlord's interest
in the Premises, Landlord shall transfer the Security Deposit to Landlord's
successor-in-interest whereupon Landlord shall be released from liability for
the return of the Security Deposit or the accounting therefor.

      8.  Holding Over.
          ------------ 

          Tenant shall have no right to holdover possession of the Premises
after the expiration or termination of this Lease.  If, however, Tenant remains
in possession of all or any part of the Premises after the expiration of the
Term, or the extended term, if extended, such tenancy shall be month-to-month
only and shall not constitute a renewal or extension for any further term.  If
Tenant remains in possession either with or without Landlord's consent, Monthly
Rent shall be increased to an amount equal to one hundred fifty percent (150%)
of the Monthly Rent payable during the last month of the Term, and any other
sums due under this Lease shall be payable in the amount and at the times
specified in this Lease.  Such month-to-month tenancy shall be subject to every
other term, condition, and covenant contained herein.  If Tenant fails to
surrender the Premises upon the expiration of the Term despite demand to do so
by Landlord, Tenant shall indemnify and hold Landlord harmless from all loss or
liability, including without limitation any claim made by a succeeding tenant,
resulting from Tenant's failure to surrender.

      9.  Tenant Improvements.
          ------------------- 

          If Tenant Improvements are to be constructed within the Premises by
Tenant, Tenant agrees to construct such Tenant Improvements pursuant to the
terms of EXHIBIT B.  Tenant covenants that the Tenant Improvements (as defined
         ---------                                                            
in EXHIBIT B) to be installed in the Premises by Tenant will be valued at at
   ---------                                                                
least Twenty and no/100ths Dollars ($20.00) per square foot.  The Tenant
Improvements shall be and remain the property of Tenant during the Term of this
Lease but shall become the property of Landlord, and shall remain upon the
Premises, upon the expiration or sooner termination of this Lease.  Landlord
shall have the right, however, to require Tenant to remove any special purpose
Tenant Improvements from the Premises if Landlord has indicated in writing at
the time of Landlord's approval of the Tenant Improvements that such removal
will be required upon the termination of this Lease.  For purposes of this
Lease, "special purpose Tenant Improvements" shall mean those Tenant
Improvements which are special or unique to Tenant's

                                      -6-
<PAGE>
 
business and which would not be usable by an average tenant occupying the
Premises for the uses permitted under Paragraph 11.A. of this Lease. Any
cubicles installed in the Premises by Tenant shall not be considered Tenant
Improvements or Alterations but shall be and remain Tenant's Personal Property
and may be removed from the Premises by Tenant at any time.

      10. Condition of Premises.
          --------------------- 

          Landlord represents and warrants to Tenant that, to the best of
Landlord's knowledge, as of the date that Landlord delivers possession of the
Premises to Tenant, all structural portions of the Premises, including, without
limitation, the roof, the foundation, exterior walls and interior load-bearing
walls; all paved surfaces; the roof membrane; and all sewer, plumbing and HVAC
systems currently serving the Premises will be in good operating condition,
order and repair.  Subject to the foregoing representation and warranty, by
taking possession of the Premises, Tenant shall be deemed to have accepted the
Premises in its then current condition, "as is," subject to all applicable Laws.
Except as expressly set forth herein, Tenant acknowledges that neither Landlord
nor Landlord's Agents have made any representations or warranties as to
condition of the Premises or the suitability or fitness of the Premises for the
conduct of Tenant's business or for any other purpose, nor has Landlord or
Landlord's Agents agreed to undertake any Alterations or construct any Tenant
Improvements to the Premises.

      11. Use of the Premises.
          ------------------- 

          A.   Tenant's Use.  Tenant shall use the Premises solely for research
               ------------                                                    
& development and general office purposes and shall not use the Premises for any
other purpose without the prior written consent of Landlord, which consent shall
not be unreasonably withheld. Tenant acknowledges that the Premises are subject
and this Lease is subordinate to any covenants, conditions and restrictions
which may be recorded against the Premises.  Throughout the Term, Tenant shall
not violate any such covenants, conditions and restrictions.

          B.   Compliance.
               ---------- 

               (i)   Tenant shall not use the Premises or suffer or permit
anything to be done in or about the Premises which will in any way conflict with
any law, statute, zoning restriction, ordinance or governmental law, rule,
regulation or requirement of public authorities now in force or which may
hereafter be in force, relating to or affecting the condition, use or occupancy
of the Premises. Tenant shall not commit any public or private nuisance or any
other act or thing which might or would disturb the quiet enjoyment of any
occupant of nearby property. Tenant shall place no loads upon the floors, walls
or ceilings in excess of the maximum designed load for the Building or which
endanger the structure; nor place any harmful liquids in the drainage systems;
nor dump or store waste materials or refuse or allow such to remain outside the
Building proper, except in the enclosed trash areas provided. Tenant shall not
store or permit to be stored or otherwise placed any other material of any
nature whatsoever outside the Building, except in designated storage areas
reasonably approved by Landlord.

                                      -7-
<PAGE>
 
               (ii)  In particular, Tenant, at its sole cost, shall comply with
all laws relating to the storage, use and disposal of hazardous, toxic or
radioactive matter by Tenant during the Term of this Lease, including those
materials identified in Sections 66680 through 66685 of Title 22 of the
California Code of Regulations, Division 4, Chapter 30 as they may be amended
from time to time (collectively "Hazardous Materials"). If Tenant does store,
use or dispose of any Hazardous Materials, Tenant shall notify Landlord in
writing at least ten (10) days prior to their first appearance on the Premises.
Tenant shall be solely responsible for and shall indemnify, defend, protect and
hold harmless Landlord and Landlord's Agents from and against all costs, claims,
damages, liabilities and expenses (including reasonable attorneys' and
consultants' fees) arising out of or in connection with any storage, use,
generation, release or disposal of Hazardous Materials in, on or about the
Premises by Tenant, its agents, employees, contractors, invitees or subtenants
during the Term of this Lease or during the early entry period described in
Paragraph 4.C. above, which indemnity shall include, without limitation, damages
for personal or bodily injury, property damage, damage to the environment or
natural resources occurring on or off the Premises, and the cost of any
investigation, monitoring, government oversight, removal, remediation,
restoration, abatement and disposal. If any governmental agency or the
beneficiary of any deed of trust covering the Premises requires any testing of
the Premises, including the soil or groundwater of the Premises, to ascertain
whether there has been any release of Hazardous Materials in, on or about the
Premises, then upon reasonable prior notice to Tenant Landlord shall have the
right to install monitoring wells on or about the Outside Area and to perform
such other tests and investigations of the Premises for such purpose. Tenant
shall reimburse Landlord as Additional Rent for the reasonable cost of such
tests and investigations and of the installation, maintenance, repair and
replacement of such monitoring wells or other measuring devices to the extent
the results of such tests and investigations disclose that such Hazardous
Materials were used, stored, generated, released or disposed of in, on or about
the Premises by Tenant, its agents, employees, contractors, invitees or
subtenants during the Term of this Lease or during the early entry period
described in Paragraph 4.C. above. Tenant's obligations hereunder shall survive
the termination of this Lease.

               (iii) Landlord represents that, to the best of Landlord's actual,
current knowledge, based on the results of that certain Phase I Site Assessment
prepared by Tetra Tech and dated as of September 1992 (the "Environmental
Report"): (A) there are no Hazardous Materials present on or about the Premises
or the soil, surface water or ground water of the Premises; (B) no underground
storage tanks or asbestos-containing building materials ("ACM's") are present on
the Premises, except for the possible presence of ACM's in the Building's floor
tiles, as disclosed by the Environmental Report; and (C) no action, proceeding,
or claim is pending or threatened against the Premises with respect to any
Hazardous Materials. Tenant shall not be liable for, and Landlord shall
indemnify, defend, protect and hold harmless Tenant, its agents, employees,
shareholders, directors, and officers from and against all costs, claims,
damages, liabilities and expenses (including reasonable attorneys' and
consultants' fees) arising out of or in connection with any Hazardous Materials
which were present on or about the Premises or the soil, surface water or ground
water of the Premises as of the date that Landlord delivers possession of the
Premises to Tenant including, without limitation, any Hazardous Materials that
may be disclosed by the Environmental Report or that certain Asbestos Survey
prepared by Dames and Moore dated June 1, 1997, Job #19150-005-043, or any
Hazardous Materials used, released, discharged, emitted or disposed of on or
about the Premises by Landlord or Landlord's Agents or contractors.

                                      -8-
<PAGE>
 
               (iv)  The provisions of Paragraphs 11.B.(ii)-(iv) constitute the
entire agreement between Landlord and Tenant regarding Hazardous Materials and
the parties agree that no other provision of this Lease shall be deemed to apply
thereto.

      12. Quiet Enjoyment.
          --------------- 

          Landlord covenants that Tenant, upon performing the terms, conditions
and covenants of this Lease, shall have quiet and peaceful possession of the
Premises as against any person claiming the same by, through or under Landlord.

      13. Alterations.
          ----------- 

          After the Commencement Date, Tenant shall not make any Alterations in,
on or about the Premises, except for nonstructural Alterations not exceeding
Ten Thousand Dollars ($10,000.00) in cost per Alteration, without the prior
written consent of Landlord, and according to plans and specifications approved
in writing by Landlord, which consent shall not be unreasonably withheld.
Notwithstanding the foregoing Tenant shall not, without the prior written
consent of Landlord, make any (i) Alterations to the exterior of the Building;
(ii) Alterations to and penetrations of the roof of the Building; and (iii)
Alterations to the Outside Area, to which Landlord may withhold Landlord's
consent on wholly aesthetic grounds.  All Alterations shall be installed at
Tenant's sole expense (except as otherwise provided in EXHIBIT B), in compliance
                                                       ---------                
with all applicable  Laws, by a licensed contractor, shall be done in a good and
workmanlike manner conforming in quality and design with the Premises existing
as of the Commencement Date, and shall not diminish the value of the Premises.
Tenant shall give Landlord written notice of Tenant's intention to perform work
on the Premises at least ten (10) days prior to the commencement of such work to
enable Landlord to post and record a Notice of Nonresponsibility or other notice
deemed proper before the commencement of any such work.  If Landlord's consent
is required for any Alteration, Landlord shall notify Tenant in writing of its
approval or disapproval thereof, specifying in reasonable detail the basis for
disapproval, if applicable, within ten (10) business days after Landlord's
receipt of reasonably detailed plans and specifications, if applicable, for the
proposed Alterations.  If Landlord fails to notify Tenant of approval or
disapproval within such 10-day period, Tenant may again request approval of such
Alterations in writing.  If Landlord fails to notify Tenant of Landlord's
approval or disapproval of such Alterations within five (5) business days after
Landlord's receipt of Tenant's second notice, then Landlord shall be deemed to
have approved the proposed Alterations as shown on the plans and specifications
provided to Landlord.  Upon request, Landlord shall advise Tenant in writing
whether Landlord reserves the right to require Tenant to remove any Alterations
from the Premises upon termination of the Lease.  If Landlord fails to require
removal upon such request, Tenant shall not be required to remove such
Alterations from the Premises.  All Alterations and Tenant Improvements
installed at Tenant's expense shall remain Tenant's property during the Term of
this Lease and Tenant shall be entitled to all depreciation, amortization and
other tax benefits with respect thereto.  Except for Alterations which cannot be
removed without structural damage to the Premises, Tenant may remove any
Alterations from the Premises at any time provided Tenant repairs all damage
caused by such removal.  Notwithstanding any other provision of this Lease,
Tenant shall be solely responsible for the maintenance and repair of any and all
Alterations made by it to the Premises.

                                      -9-
<PAGE>
 
      14. Surrender of the Premises.
          ------------------------- 

          Upon the expiration or earlier termination of the Term, Tenant shall
surrender the Premises to Landlord in the same condition and repair as on the
Commencement Date, normal wear and tear and damage by fire or other casualty,
acts of God and condemnation, Hazardous Materials which are not released or
emitted in, on or under the Premises during the Term of this Lease by Tenant,
its agents, employees, contractors or invitees, and Alterations and Tenant
Improvements which Tenant is not required to remove under the terms of this
Lease all excepted.  The Tenant Improvements and Alterations installed in the
Building by Tenant shall become Landlord's property upon the expiration or
sooner termination of this Lease and shall remain in and be surrendered with the
Building unless Landlord has previously notified Tenant in writing that Landlord
desires to have Tenant remove any special purpose Tenant Improvements or
Alterations from the Premises.  In such event Tenant shall remove such special
purpose Tenant Improvements and such Alterations from the Premises, as well as
Tenant's Personal Property, and repair any damage and perform any restoration
work caused by such removal.  If Tenant fails to remove such special purpose
Tenant Improvements or such Alterations or any of Tenant's Personal Property,
and such failure continues after the termination of this Lease, Landlord may
retain such property and all rights of Tenant with respect to it shall cease, or
Landlord may place all or any portion of such property in public storage for
Tenant's account. Tenant shall be liable to Landlord for costs of removal of any
such special purpose Tenant Improvements, Alterations and Tenant's Personal
Property and storage and transportation costs of same, and the cost of repairing
and restoring the Premises, together with interest at the Interest Rate from the
date of expenditure by Landlord.  If  Landlord elects to sell any of Tenant's
Personal Property which remains on the Premises after the termination of this
Lease, Landlord shall provide Tenant with at least five (5) days' prior written
notice of such sale.  If the Premises are not surrendered at the termination of
this Lease in the condition required herein, Tenant shall indemnify Landlord and
Landlord's Agents against all loss or liability, including reasonable attorneys'
fees and costs, resulting from delay by Tenant in so surrendering the Premises.

          Normal wear and tear, for the purposes of this Lease, shall be
construed to mean wear and tear caused to the Premises by a natural aging
process which occurs in spite of prudent application of the best standards for
maintenance, repair and janitorial practices.  It is not intended, nor shall it
be construed, to include items of neglected or deferred maintenance which would
have or should have been attended to during the Term of the Lease if the best
standards had been applied to properly maintain and keep the Premises at all
times in good condition and repair.

      15. Real Property Taxes.
          ------------------- 

          A.   Payment by Tenant.  Tenant shall pay  to Landlord monthly, as
               -----------------                                            
Additional Rent, on or before the first day of each calendar month of the Term,
one-twelfth of the annual Real Property Taxes for the Premises as set forth on
the county assessor's tax statement for such period. If Tenant fails to pay any
Real Property Taxes when due, Tenant shall pay to Landlord any penalty incurred
by such late payment.  Tenant shall pay any Real Property Tax not included
within the county tax assessor's tax statement within ten (10) days after being
billed for same by Landlord. Assessments, taxes, fees, levies and charges may be
imposed by governmental agencies for such purposes as fire protection, street,
sidewalk, road, utility construction and maintenance, refuse

                                      -10-
<PAGE>
 
removal and for other governmental services which may formerly have been
provided without charge to property owners or occupants. It is the intention of
the parties that all new and increased assessments, taxes, fees, levies and
charges are to be included within the definition of Real Property Taxes for
purposes of this Lease.

          B.   Taxes on Tenant Improvements and Personal Property.  Tenant shall
               --------------------------------------------------               
pay any increase in Real Property Taxes resulting from any and all Alterations
and Tenant Improvements of any kind whatsoever placed in, on or about the
Premises for the benefit of, at the request of, or by Tenant.  Tenant shall pay
prior to delinquency all taxes assessed or levied against Tenant's Personal
Property in, on or about the Premises or elsewhere.  When possible, Tenant shall
cause its Personal Property to be assessed and billed separately from the real
or personal property of Landlord.

          C.   Proration.  Tenant's liability to pay Real Property Taxes shall
               ---------                                                      
be prorated on the basis of a 365-day year to account for any fractional portion
of a fiscal tax year included at the commencement or expiration of the Term.
With respect to any assessments which may be levied against or upon the
Premises, or which under the Laws then in force may be evidenced by improvements
or other bonds or may be paid in annual installments, only the amount of such
annual installment (with appropriate proration for any partial year) and
interest due thereon shall be included within the computation of the annual Real
Property Taxes levied against the Premises.

      16. Utilities and Services.
          ---------------------- 

          Tenant shall be responsible for and shall pay promptly all charges for
water, gas, electricity, telephone, refuse pickup, janitorial service and all
other utilities used by Tenant in, on or about the Premises during the Term,
together with any taxes thereon.  Landlord shall not be liable in damages or
otherwise for any failure or interruption, of any utility service or other
service furnished to the Premises, except that resulting from the gross
negligence or willful misconduct of Landlord or Landlord's Agents.  In addition,
Tenant shall not be entitled to any abatement or reduction of Rent by reason of
such failure or interruption, no eviction of Tenant shall result from such
failure or interruption and Tenant shall not be relieved from the performance of
any covenant or agreement in this Lease because of such failure or interruption;
provided, however, that in the event Tenant's use or occupancy of the Premises
is materially impaired as a result of any failure or interruption of utilities,
and such impairment continues for three (3) consecutive business days or longer,
then Rent shall be abated proportionately, to the extent of such impairment and
for the duration of such impairment, if and only if such failure or interruption
was caused by the gross negligence or willful misconduct of Landlord or
Landlord's Agents or contractors, or the abatement of Rent will be covered by
Landlord's rent loss insurance or other insurance maintained by Landlord.
Furthermore, if any failure or interruption of utilities occurs that materially
impairs Tenant's use or occupancy of the Premises for ninety (90) consecutive
days or longer, then so long as such failure or interruption was not caused by
the negligence or willful misconduct of Tenant, its agents, employees,
contractors, or invitees, Tenant shall have the right to terminate this Lease
upon written notice to Landlord.

      17. Repair and Maintenance.
          ---------------------- 

          A.   Landlord's Obligations.  Landlord shall keep in good order,
               ----------------------                                     
condition and repair the structural parts of the Building, which structural
parts include only the foundation and subflooring of the Building and the
structural condition of the roof and the exterior walls of the Building (but
excluding interior surfaces of exterior walls, windows, doors which shall be
maintained and repaired by Tenant), except that any damage to any of the
foregoing caused by the negligence or willful acts or omissions of Tenant or of
Tenant's agents, employees or invitees, or by reason of the failure of Tenant to
perform any of its repair and maintenance obligations in accordance with the
terms of this Lease, or caused by Alterations made by Tenant or by Tenant's
agents, employees or contractors shall be repaired by Tenant, at Tenant's
expense, with contractors approved by Landlord. It is an express condition
precedent to all obligations of Landlord to repair that Tenant shall have
notified Landlord of the need for such repairs. Tenant waives the provisions of
Sections 1941 and 1942 of the California Civil Code and any similar or successor
law regarding Tenant's right to make repairs and deduct the expenses of such
repairs from the Rent due under this Lease.

          B.   Tenant's Obligations.  Tenant shall at all times and at its own
               --------------------                                           
expense clean, keep and maintain in good order, condition and repair every part
of the Premises which is not  within Landlord's obligation pursuant to Paragraph
17.A.  Tenant's repair and maintenance obligations shall include all parking
areas, sidewalks, driveways, entrances and exits, landscaping and exterior
lighting, all plumbing and sewage facilities within the Building, fixtures,
interior walls and ceiling, the roof membrane, floors, windows, doors,
entrances, plateglass, showcases, skylights, all electrical facilities and
equipment, including lighting fixtures, lamps, fans and any exhaust equipment
and systems, the HVAC system, any automatic fire extinguisher equipment within
the Premises, electrical motors and all other appliances and equipment of every
kind and nature located in, upon or about the Premises.  Notwithstanding the
foregoing, if the roof membrane requires replacement during the Term of this
Lease, including any extended term, then Landlord shall replace the roof
membrane and the cost of such replacement shall be paid by Landlord and Tenant
as follows. The cost to replace the roof membrane shall be fully amortized on a
straight-line basis over the useful life of the roof membrane and Tenant shall
pay to Landlord, within thirty (30) days after receipt of an itemized invoice
for the cost of replacing the roof membrane, the amortized portion of such cost
that is allocable to the then remaining Term of this Lease.  For instance, if
the useful life of the roof membrane is twenty (20) years and, at the time the
roof membrane is replaced there are three (3) years remaining in the Term, then
Tenant would pay to Landlord three-tenths (3/20ths) of the cost of such
replacement and Landlord would pay the balance.  If, however, the Term of this
Lease is extended as provided in Paragraph 39, then Tenant shall pay to Landlord
the amortized portion of the cost that is allocable to such extended Term.  If
this Lease is terminated prior to the expiration of the Term or any extended
Term, for any reason other than a default by Tenant, then Landlord shall
reimburse Tenant that portion of the amortized cost of such replacement that is
allocable to the period from the date of termination until the expiration date
of the Term or the extended Term, as applicable.  The cost for replacement shall
be reasonably incurred and shall  be consistent with replacement costs charged
by owners of buildings of similar age and construction in Santa Clara County for
similar replacements. Tenant shall also be responsible for all pest control
within the Premises.  Landlord shall assign to Tenant any warranties with
respect to the Premises which would

                                      -12-
<PAGE>
 
reduce Tenant's maintenance obligations under this Lease and shall cooperate
with Tenant to enforce such warranties.

               Tenant shall obtain HVAC systems preventive maintenance contracts
with bimonthly or monthly service in accordance with manufacturer
recommendations, which shall be subject to the reasonable approval of Landlord
and paid for by Tenant, and which shall provide for and include replacement of
filters, oiling and lubricating of machinery, parts replacement, adjustment of
drive belts, oil changes and other preventive maintenance, including annual
maintenance of duct work, interior unit drains and caulking at sheet metal, and
recaulking of jacks and vents on an annual basis. Tenant shall have the benefit
of all warranties available regarding the equipment in such HVAC systems.
Landlord may, at Landlord's election, have the HVAC systems inspected by a
licensed HVAC contractor at the expiration of the Term to confirm whether Tenant
has maintained the HVAC systems as required herein. The cost of such inspection
shall be paid by Tenant within ten (10) days after Landlord's written request
therefor. Additionally, if any repairs and/or replacements to the HVAC system
are recommended by the contractor, Tenant shall perform such repairs and/or
replacements and shall provide Landlord with evidence that such repairs and/or
replacements have been completed in accordance with the contractor's
recommendations. If at any time during the Term of this Lease Landlord
determines that Tenant is not maintaining the roof membrane and/or the HVAC
system in good order, condition and repair as required herein, Landlord may,
upon not less than thirty (30) days prior written notice to Tenant, elect to
assume the obligation to maintain and repair the roof membrane and/or the HVAC
system, as applicable, and to enter into one or more maintenance contracts with
third parties for the provision of such repair and maintenance obligations. Upon
such election, Tenant shall be relieved from its obligations to perform only
those maintenance and repair obligations covered by such maintenance contracts,
and Tenant shall pay Landlord monthly as Additional Rent the cost of such
maintenance contracts, including the cost of any maintenance, repairs and
replacements incurred thereunder.

          D.   Compliance with Governmental Regulations.  Subject to the
               ----------------------------------------                 
provisions of Exhibit B, Tenant shall, at its cost, comply with all present and
              ---------                                                        
future regulations, rules, laws, ordinances, and requirements of all
governmental authorities, including, without limitation state, municipal, county
and federal governments and their departments, bureaus, boards and officials
(collectively, "Laws"), arising from Tenant's use or occupancy of the Premises;
provided, however, that Tenant shall not be required to make any alterations or
improvements to the Premises that are required to comply with any Laws unless
such alterations or improvements are required by Laws applicable to the Premises
and effective after the Commencement Date, and provided further that Tenant
shall not be required to make any capital or structural improvements to the
Premises unless such compliance is necessitated solely as a result of Tenant's
particular use of the Premises or any Alterations to the Premises made by
Tenant.  If any capital or structural improvements to the Premises are required
to comply with any Laws applicable to the Premises and effective after the
Commencement Date and such improvements are not required solely as a result of
Tenant's particular use of the Premises or any Alterations to the Premises made
by Tenant, then such improvements shall be made by Landlord and the cost of such
improvements shall be allocated between Landlord and Tenant as follows.  The
cost of such improvements shall be fully amortized on a straight-line basis over
the useful life of such improvements and Tenant shall pay to Landlord, within
thirty (30) days after receipt of a description of the improvements to be
completed and an

                                      -13-
<PAGE>
 
itemized invoice for the cost of designing, constructing and/or installing such
improvements in the Premises, the amortized portion of such cost that is
allocable to the then remaining Term of this Lease. For instance, if the useful
life of the improvements is ten (10) years and, at the time the improvements are
completed there are three (3) years remaining in the Term, then Tenant would pay
to Landlord three-tenths (3/10ths) of the cost of such improvements and Landlord
would pay the balance. If, however, the Term of this Lease is extended as
provided in Paragraph 39, then Tenant shall pay to Landlord the amortized
portion of the cost that is allocable to such extended Term. If this Lease is
terminated prior to the expiration of the Term or any extended Term, for any
reason other than a default by Tenant, then Landlord shall reimburse Tenant that
portion of the amortized cost of such improvements that is allocable to the
period from the date of termination until the expiration date of the Term or the
extended Term, as applicable.

      18. Liens.
          ----- 

          Tenant shall keep the Premises free from any liens arising out of any
work performed, materials furnished or obligations incurred by or on behalf of
Tenant and hereby indemnifies and holds Landlord and Landlord's Agents harmless
from all liability and cost, including attorneys' fees and costs, in connection
with or arising out of any such lien or claim of lien. Tenant shall cause any
such lien imposed to be released of record by payment or posting of a proper
bond acceptable to Landlord within ten (10) days after written request by
Landlord.  Tenant shall give Landlord written notice of Tenant's intention to
perform work on the Premises which might result in any claim of lien at least
ten (10) days prior to the commencement of such work to enable Landlord to post
and record a Notice of Nonresponsibility.  If Tenant fails to so remove any such
lien within the prescribed ten (10) day period, then Landlord may do so at
Tenant's expense and Tenant shall reimburse Landlord as Additional Rent for such
amounts upon demand.  Such reimbursement shall include all costs incurred by
Landlord including Landlord's reasonable attorneys' fees with interest thereon
at the Interest Rate.

      19. Landlord's Right to Enter the Premises.
          -------------------------------------- 

          Tenant shall permit Landlord and Landlord's Agents to enter the
Premises at all reasonable times with  written notice, except for emergencies in
which case no notice shall be required, to inspect  the same, to post Notices of
Nonresponsibility and similar notices , to show the Premises to interested
parties such as prospective lenders and purchasers, to make necessary repairs,
to discharge Tenant's obligations hereunder when Tenant has failed to do so
within  thirty (30) days after written notice from Landlord (or such longer time
as may be reasonably necessary to complete the performance of such obligation so
long as Tenant is diligently pursuing such performance to completion), and at
any reasonable time within one hundred and  twenty (120) days prior to the
expiration of the Term, to place upon the Building ordinary "For Lease" signs
and to show the Premises to prospective tenants.  The above rights are subject
to reasonable security regulations of Tenant, and to the requirement that
Landlord shall at all times act in a manner to cause the least possible
interference with Tenant's business and shall be accompanied by a representative
of Tenant during any scheduled entry and, to the extent reasonably possible,
during emergencies.

                                      -14-
<PAGE>
 
      20. Signs.
          ----- 

          Tenant shall have the right to install a Tenant identification sign on
the monument sign structure located in the Outside Area of the Premises and in
any other location  on the Building or in the Outside Area permitted by
applicable Laws.  The size, design, color and other physical aspects of  any
Tenant identifications sign shall be subject to Landlord's written approval
prior to installation, which approval shall not be unreasonably withheld, the
CC&R's and any appropriate municipal or other governmental approvals.  The cost
of  any signs, their installation, maintenance and removal expense shall be
Tenant's sole expense.  If Tenant fails to maintain its  signs, or, if Tenant
fails to remove its  signs upon termination of this Lease, Landlord  may do so
at Tenant's expense and Tenant's reimbursement to Landlord for such amounts
shall be deemed Additional Rent.

      21. Insurance.
          --------- 

          A.   Indemnification.
               --------------- 

               (i)   Tenant hereby agrees to defend, indemnify, protect, and
hold harmless Landlord and Landlord's Agents from and against any and all
damage, loss, liability or expense, including attorneys' fees and legal costs,
suffered directly or by reason of any claim, suit or judgment brought by or in
favor of any person or persons for damage, loss or expense due to, but not
limited to, bodily injury and property damage sustained by such person or
persons to the extent arising out of, occasioned by or in any way attributable
to the use or occupancy of the Premises or any part thereof by Tenant, the acts
or omissions of Tenant, its agents, employees or any contractors brought onto
the Premises by Tenant, except to the extent caused by the gross negligence or
willful misconduct of Landlord or Landlord's Agents or contractors. Tenant
agrees that the obligations assumed herein shall survive this Lease.

               (ii)  Landlord hereby agrees to defend, indemnify, protect, and
hold harmless Tenant from and against any and all damage, loss, liability or
expense, including attorneys' fees and legal costs, suffered directly or by
reason of any claim, suit or judgment brought by or in favor of any person or
persons for damage, loss or expense due to, but not limited to, bodily injury
and property damage sustained by such person or persons to the extent arising
from the negligence or willful misconduct of Landlord or Landlord's Agents or
contractors or from Landlord's violation of applicable Laws. Landlord agrees
that the obligations assumed herein shall survive this Lease.

          B.   Tenant's Insurance.  Tenant agrees to maintain in full force and
               ------------------                                              
effect at all times during the Term, at its own expense, for the protection of
Tenant and Landlord, as their interests may appear, policies of insurance issued
by a responsible carrier or carriers acceptable to Landlord which afford the
following coverages:

               (i)   Commercial general liability insurance protecting Landlord
and Tenant against claims for bodily injury, personal injury and property damage
based upon or arising out of the use, occupancy or maintenance of the Premises.
Such insurance shall be on an occurrence basis providing single limit coverage
in an amount not less than Two Million and no/100ths Dollars ($2,000,000.00) per
occurrence with an "Additional Insured - Managers or Lessors of Premises

                                      -15-
<PAGE>
 
Endorsement" and contain the "Amendment of the Pollution Exclusion Endorsement"
for damage caused by heat, smoke or fumes from a hostile fire.   The policy
shall not contain any intra-insured exclusions between insured persons or
organizations, but shall include coverage for liability assumed under this Lease
as an "insured contract" for the performance of Tenant's indemnity obligations
under this Lease.  All insurance carried by Tenant shall be primary to and not
contributing with any similar insurance carried by Landlord, whose insurance
shall be considered excess insurance only.

               (ii)  "All-risk" or causes of loss-special form property
insurance (including, without limitation, vandalism, malicious mischief,
inflation endorsement, and sprinkler leakage endorsement) on Tenant's Personal
Property located on or in the Premises and any Alterations to the Premises
constructed by Tenant at Tenant's expense. Such insurance shall be in the full
amount of the replacement cost, as the same may from time to time increase as a
result of inflation or otherwise. Landlord shall have no interest in the
insurance proceeds on Tenant's Personal Property, any Alterations to the
Premises constructed at Tenant's expense, or any additional insurance that
Tenant may elect to maintain with respect to the Tenant Improvements.

          C.   Premises Insurance.  During the Term Landlord shall maintain
               ------------------                                          
"all-risk" or causes of loss - special form property insurance (including
vandalism, malicious mischief, inflation endorsement, sprinkler leakage
endorsement) and earthquake insurance on the Building in the full amount of the
replacement cost thereof, excluding coverage of all Tenant's Personal Property
or Alterations located on or in the Premises, but including the Tenant
Improvements.  Such insurance shall also include insurance against loss of rents
on an all-risk basis and coverage for earthquake  in an amount equal to the
Monthly Rent and Additional Rent, and any other sums payable under the Lease,
for a period of twelve (12) months commencing on the date of loss.  Such
insurance shall name Landlord and Landlord's Agents as named insureds and
include a lender's loss payable endorsement in favor of Landlord's lender (Form
438 BFU Endorsement).  Tenant shall reimburse Landlord annually, as Additional
Rent, for the annual premiums for such insurance within thirty (30) days after
Tenant's receipt of an invoice therefor.  For the first year of the Term, the
total premiums for Landlord's insurance, including earthquake insurance, shall
not exceed Eighteen Thousand Five Hundred and no/100ths Dollars ($18,500.00).
If the property insurance premiums are increased after the Commencement Date,
due to an increase in the value of the Building or its replacement cost, or due
to Tenant's use of the Premises or any improvements installed by in the Building
by Tenant, Tenant shall pay such increase within ten (10) days of notice of such
increase.  Any insurance maintained by Landlord covering the Premises and/or the
Tenant Improvements shall be primary to and not contributing with any insurance
maintained by Tenant covering the Premises and/or the Tenant Improvements, which
insurance shall be considered excess insurance only.

          D.   Increased Coverage.  Upon demand, Tenant shall provide Landlord,
               ------------------                                              
at Tenant's expense, with such increased amount of existing insurance, and such
other insurance as Landlord or Landlord's lender may reasonably require to
afford Landlord and Landlord's lender adequate protection; provided that such
increased insurance or other insurance is warranted due to a substantial change
in the nature of Tenant's operations at the Premises and the increased risks
associated therewith or due to the total amount of any claims paid on Tenant's
insurance policies in the prior twelve (12) month period, or such insurance is
customarily required for similar uses by owners of comparable buildings in Santa
Clara County.

                                      -16-
<PAGE>
 
          E.   Co-Insurer.  If, on account of Tenant's failure to maintain any
               ----------                                                     
of the insurance required by this Lease, Landlord is adjudged a co-insurer by
its insurance carrier, then, any loss or damage Landlord shall sustain by reason
thereof, including attorneys' fees and costs, shall be borne by Tenant and shall
be immediately paid by Tenant upon receipt of a bill therefor and evidence of
such loss.

          F.   Insurance Requirements.  All insurance shall be in a form
               ----------------------                                   
satisfactory to Landlord and shall be carried with companies that have a general
policy holder's rating of not less than "A" due to Tenant's use of the Premises,
improvements installed by Tenant and a financial rating of not less than Class
"X" in the most current edition of Best's Insurance Reports; shall provide that
                                   ------------------------                    
such policies shall not be subject to material alteration or cancellation except
after at least thirty (30) days' prior written notice to Landlord.  The policy
or policies, or duly executed certificates for them, together with satisfactory
evidence of payment of the premium thereon shall be deposited with Landlord
prior to the Commencement Date, and upon renewal of such policies, not less than
thirty (30) days prior to the expiration of the term of such coverage.  If
Tenant fails to procure and maintain the insurance required hereunder, Landlord
may, but shall not be required to, order such insurance at Tenant's expense and
Tenant shall reimburse Landlord upon demand.  Such reimbursement shall include
all costs incurred by Landlord including Landlord's reasonable attorneys' fees,
with interest thereon at the Interest Rate.

          G.   Landlord's Disclaimer.  Neither Landlord nor Landlord's Agents
               ---------------------                                         
shall be liable for any loss or damage to persons or property resulting from
fire, explosion, falling plaster, glass, tile or sheetrock, steam, gas,
electricity, water or rain which may leak from any part of the Building or from
the pipes, appliances or plumbing works therein or from the roof, street or
subsurface, or from any other cause whatsoever, unless caused by or due to the
sole negligence or willful misconduct of Landlord or Landlord's Agents or
contractors.   Tenant shall give prompt written notice to Landlord in case of a
casualty, accident or repair needed in the Premises.

      22. Waiver of Subrogation.
          --------------------- 

          Notwithstanding anything to the contrary in this Lease, Landlord and
Tenant each hereby release each other and their respective agents, employees,
successors, assigns and Subtenants (so long as in the event of any Sublet such
Subtenant provides a mutual release to Landlord), from any liability for, and
waive all rights of recovery against the other on account of, loss or damage
occasioned to such waiving party for its property or the property of others
under its control to the extent that such loss or damage would be covered by a
standard form policy of all-risk or causes of loss - special form insurance
(including, without limitation, vandalism, malicious mischief, inflation
endorsement, and sprinkler leakage endorsement) or is otherwise insured against
by Landlord or Tenant under any insurance policies which may be in force at the
time of such loss or damage, without regard to the negligence or willful
misconduct of the party so released.  Tenant and Landlord shall, upon obtaining
policies of insurance required hereunder, give notice to the insurance carrier
that the foregoing mutual waiver of subrogation is contained in this Lease and
Tenant and Landlord shall cause each insurance policy obtained by such party to
provide that the insurance company waives all right of recovery by way of
subrogation against either Landlord or Tenant in connection with any damage
covered by such policy.

                                      -17-

      23. Damage or Destruction.
          --------------------- 

          A.   Landlord's Obligation to Rebuild.  If the Premises are damaged or
               --------------------------------                                 
destroyed, Landlord shall promptly and diligently repair the same unless it has
the right to terminate this Lease as provided herein and it elects to so
terminate.

          B.   Right to Terminate.  Landlord shall have the right to terminate
               ------------------                                             
this Lease in the event any of the following events occur:

               (i)   The cost to repair any uninsured damage to the Premises
exceeds One Hundred Fifty Thousand and no/100ths Dollars ($150,000.00) and
Tenant has not agreed to pay the cost of repair in excess of One Hundred Fifty
Thousand Dollars ($150,000.00);

               (ii)  The Building cannot, with reasonable diligence, be fully
repaired by Landlord within two hundred forty (240) days after the date of the
damage or destruction; or

               (iii) The Building cannot be safely repaired because of the
presence of hazardous factors, including, but not limited to, earthquake faults,
radiation, chemical waste and other similar dangers.

          If Landlord elects to terminate this Lease, Landlord may give Tenant
written notice of its election to terminate within thirty (30) days after such
damage or destruction, and this Lease shall terminate fifteen (15) days after
the date Tenant receives such notice.  In such event, Landlord shall pay to
Tenant from any insurance proceeds received by Landlord an amount equal to the
then unamortized portion of the cost of the Tenant Improvements in excess of
$10.00 per square foot. For example, if the casualty occurred during the forty-
eighth month of the Term, and the original cost of the Tenant Improvements was
$30.00 per square foot, or $979,800.00, then $20.00 per square foot, or
$653,200.00, would be fully amortized over the seven-year Term, and 3/7ths of
such amount, or $279,942.86, would be paid to Tenant from the insurance proceeds
received by Landlord.  If Landlord elects not to terminate the Lease, subject to
Tenant's termination right set forth below, Landlord shall promptly commence the
process of obtaining necessary permits and approvals and repair of the Building
as soon as practicable, and this Lease will continue in full force and effect.
All insurance proceeds from insurance under Paragraph 21.C., excluding proceeds
for Tenant's Personal Property and Alterations, shall be disbursed and paid to
Landlord.

          Tenant shall be required to pay to Landlord the amount of any
deductible payable in connection with Landlord's all risk or causes of loss-
special form policy of insurance (which deductible shall not exceed $5,000.00
per occurrence without the prior written consent of Tenant), unless the casualty
was caused by the sole negligence or willful misconduct of Landlord.  Landlord
and Tenant shall each pay one-half ( 1/2) of the deductible payable under
Landlord's policy of earthquake insurance.  Landlord and Tenant agree that any
deductible payable under all earthquake insurance policies maintained by
Landlord shall not exceed a total of $300,000.00 per occurrence unless a greater
amount is agreed to by both Landlord and Tenant.  Landlord and Tenant shall
review Landlord's earthquake insurance coverage annually to determine whether
the premium and deductible payable under such policy are reasonable in light of
the coverage provided and the total

                                      -18-
<PAGE>
 
value of the improvements insured and whether Landlord should continue to
maintain earthquake insurance coverage for the Premises and the Tenant
Improvements.

          Tenant shall have the right to terminate this Lease, if the Building
cannot with reasonable diligence be fully repaired, or is not fully repaired,
within one hundred  eighty (180) days from the date of damage or destruction.
The determination of the estimated repair period shall be made by  Landlord's
architect or engineer in its good faith business judgment within thirty (30)
days after such damage or destruction.  Landlord shall deliver written notice of
the repair period to Tenant after such determination has been made and Tenant
shall exercise its right to terminate this Lease, if at all, within  thirty (30)
days of receipt of such notice from Landlord.

          C.   Limited Obligation to Repair.  Landlord's obligation, should it
               ----------------------------                                   
elect or be obligated to repair or rebuild, shall be limited to the basic
Building provided by Landlord as of the date of this Lease and the original
Tenant Improvements installed by Tenant, as the case may be, and Tenant shall,
at Tenant's expense, replace or fully repair all Tenant's Personal Property and
any Alterations installed by Tenant and existing at the time of such damage or
destruction.  Landlord shall not be entitled to share in the proceeds of any
separate insurance which may be maintained by Tenant covering the Tenant
Improvements nor shall Tenant be required to contribute the proceeds of any such
insurance to rebuild the Tenant Improvements.

          D.   Abatement of Rent.  Rent shall be temporarily abated
               -----------------                                   
proportionately during any period when, by reason of such damage or destruction,
there is  interference with Tenant's use of the Premises, having regard to the
extent to which Tenant may be required to discontinue Tenant's use of the
Premises.  Such abatement shall commence upon such damage or destruction and end
upon substantial completion by Landlord of the repair or reconstruction which
Landlord is obligated or undertakes to do.  If, however, the damage or
destruction to the Premises is caused by the negligence or willful misconduct of
Tenant, its agents or employees, Rent shall be abated only to the extent of any
proceeds received by Landlord from rental abatement insurance described in
Paragraph 21.C.  Tenant shall not be entitled to any compensation or damages
from Landlord for loss of the use of the Premises, damage to Tenant's Personal
Property or any inconvenience occasioned by such damage, repair or restoration.
Tenant hereby waives the provisions of Section 1932, Subdivision 2, and Section
1933, Subdivision 4, of the California Civil Code, and the provisions of any
similar law hereinafter enacted.

          E.   Damage Near End of Term.  Anything herein to the contrary
               -----------------------                                  
notwithstanding, if the Building is destroyed or damaged during the last twelve
(12) months of the Term, then Landlord may, at its option, cancel and terminate
this Lease as of the date of the occurrence of such damage. If Landlord does not
elect to so terminate this Lease, the repair of such damage shall be governed by
Paragraphs 23.A. and 23.B.

      24. Condemnation.
          ------------ 

          If title to all of the Building or the Premises is taken for any
public or quasipublic use under any statute or by right of eminent domain, or
title to a portion of the Building or the Premises is taken so that
reconstruction of the  Building or the Premises will not, in Landlord's and
Tenant's

                                      -19-
<PAGE>
 
mutual opinion, result in the Premises being reasonably suitable for Tenant's
continued occupancy for the uses and purposes permitted by this Lease, this
Lease shall terminate as of the date that possession of the Building or the
Premises or part thereof be taken. If as a result of any partial taking of the
Building or the Premises, the remaining portion of the Premises will not be
reasonably suitable for Tenant's continued occupancy, Tenant may terminate this
Lease by written notice to Landlord. A sale by Landlord to any authority having
the power of eminent domain, either under threat of condemnation or while
condemnation proceedings are pending, shall be deemed a taking under the power
of eminent domain for all purposes of this paragraph.

          If any part of the Building or the Premises is taken and the remaining
part is reasonably suitable for Tenant's continued occupancy for the purposes
and uses permitted by this Lease, this Lease shall, as to the part so taken,
terminate as of the date that possession of such part of the Building or the
Premises is taken.  The Rent and other sums payable hereunder shall be reduced
in the same proportion that Tenant's use and occupancy of the Premises is
reduced.  If any portion of the Outside Area is taken, Tenant's Rent shall be
reduced to the extent such taking interferes with Tenant's use of the Premises
for the purposes permitted by this Lease.  Each party hereby waives the
provisions of Section 1265.130 of the California Code of Civil Procedure
allowing either party to petition the Superior Court to terminate this Lease in
the event of a partial taking of the Premises.

          No award for any partial or entire taking shall be apportioned.
Tenant assigns to Landlord its interest in any award which may be made in such
taking or condemnation, together with any and all rights of Tenant arising in or
to the same or any part thereof; provided, however, that Landlord shall pay to
Tenant from any award received by Landlord an amount equal to the then
unamortized portion of the cost of the Tenant Improvements in excess of $10.00
per square foot, which shall be determined as described in Paragraph 23.B.
Nothing contained herein shall be deemed to give Landlord any interest in or
require Tenant to assign to Landlord any separate award made to Tenant for the
taking of Tenant's Personal Property or any Alterations, or its moving costs.

      25. Assignment and Subletting.
          ------------------------- 

          A.   Landlord's Consent.  Tenant shall not enter into a Sublet without
               ------------------                                               
Landlord's prior written consent, which consent shall not be unreasonably
withheld.  Any Sublet made without Landlord's prior written consent shall be
void and confer no rights upon any third person and, at Landlord's election,
shall terminate this Lease.  Each assignee shall agree in writing, for the
benefit of Landlord, to assume, to be bound by, and to perform the terms,
conditions and covenants of this Lease to be performed by Tenant.
Notwithstanding anything contained herein, Tenant shall not be released from
liability for the performance of each term, condition and covenant of this Lease
by reason of Landlord's consent to a Sublet unless Landlord specifically grants
such release in writing. Consent by Landlord to any Sublet shall not be deemed a
consent to any subsequent Sublet.

          B.   Information to be Furnished.  If Tenant desires at any time to
               ---------------------------                                   
Sublet the Premises or any portion thereof, it shall first notify Landlord of
its desire to do so and shall submit in writing to Landlord:  (i) the name of
the proposed Subtenant; (ii) the nature of the proposed Subtenant's business to
be carried on in the Premises; (iii) the terms and provisions of the proposed

                                      -20-
<PAGE>
 
Sublet and a copy of the proposed Sublet form containing a description of the
subject premises; and (iv) such financial information, including financial
statements, as Landlord may reasonably request concerning the proposed
Subtenant.

          C.   Landlord's Alternatives.  Within twenty (20) days after
               -----------------------                                
Landlord's receipt of the information specified in Paragraph  25.B., Landlord
shall, by written notice to Tenant, elect:  (i) to consent to the Sublet by
Tenant; or (ii) to refuse its consent to the Sublet.  If Landlord consents to
the Sublet, Tenant may thereafter enter into a valid Sublet of the Premises or
portion thereof, upon the terms and conditions and with the proposed Subtenant
set forth in the information furnished by Tenant to Landlord pursuant to
Paragraph 25.B., subject, however, at Landlord's election, to the condition that
one-half ( 1/2) of any excess of the Subrent over the sum of the Rent required
to be paid by Tenant under this Lease, plus reasonable and customary brokerage
commissions, attorneys' fees and tenant improvement costs paid by Tenant in
connection with such Sublet and, in the event of a Sublet made during the
initial Term, the then unamortized portion of the cost of the Tenant
Improvements in excess of $10.00 per square foot, shall be paid to Landlord.  If
Landlord fails to notify Tenant of its consent or refusal to grant consent to
the proposed Sublet within such 20-day period, Tenant may again request approval
of such Sublet in writing.  If Landlord fails to notify Tenant of Landlord's
consent or refusal to grant consent to such Sublet within ten (10) days after
Landlord's receipt of Tenant's second notice, then Landlord shall be deemed to
have approved the proposed Sublet as described in the information provided to
Landlord pursuant to Paragraph 25.B.

          D.   Proration.  If a portion of the Premises is Sublet, the pro rata
               ---------                                                       
share of the Rent attributable to such partial area of the Premises shall be
determined by Landlord by dividing the Rent payable by Tenant hereunder by the
total square footage of the Premises and multiplying the resulting quotient (the
per square foot rent) by the number of square feet of the Premises which are
Sublet.

          E.   Exempt Sublets.  Notwithstanding the above, Landlord's prior
               --------------                                              
written consent shall not be required for a Sublet of this Lease to (and
Landlord shall not be entitled to payment of any excess Subrent in connection
with such Sublet) a corporation controlling, controlled by or under common
control with Tenant; a subsidiary or affiliate of Tenant; a successor to Tenant
by merger, consolidation, nonbankruptcy reorganization or government action; or
a purchaser of substantially all of Tenant's assets located at the Premises
provided that (i) Tenant gives Landlord prior written notice of the name of any
such assignee, (ii) at the time of such assignment, the assignee has a net worth
that is equal to or greater than the net worth of Tenant immediately prior to
such assignment; and (iii) the assignee assumes, in writing, for the benefit of
Landlord all of Tenant's obligations under this Lease.  For purposes of this
Lease, any sale or transfer of Tenant's capital stock through any national
market system or public exchange shall not be deemed a Sublet.

      26. Default.
          ------- 

          A.   Tenant's Default.  A default under this Lease by Tenant shall
               ----------------                                             
exist if any of the following occurs:

                                      -21-
<PAGE>
 
               (i)   If Tenant fails to pay Rent or any other sum required to be
paid hereunder when due and Tenant fails to cure such breach within five (5)
days after written notice from Landlord that such Rent or other sum is past due;
provided, however, that such notice shall be in lieu of, and not in addition to,
any notice required under Section 1161 of the California Code of Civil Procedure
regarding unlawful detainer actions;

               (ii)  If Tenant fails to execute and deliver to Landlord, within
ten (10) days after Landlord's written request therefor, any subordination
documentation required under Paragraph 27, or any estoppel certificate required
under Paragraph 31;

               (iii) If Tenant fails to perform any other term, covenant or
condition of this Lease except as provided in Paragraphs 26.A.(i) or (ii) above,
and Tenant fails to cure such breach within  thirty (30) days after written
notice from Landlord where such breach could reasonably be cured within such
thirty (30) day period; provided, however, that where such failure could not
reasonably be cured within the  thirty (30) day period, that Tenant shall not be
in default if it commences such performance within the  thirty (30) day period
and diligently thereafter prosecutes the same to completion;

               (iv)  If Tenant assigns its assets for the benefit of its
creditors;

               (v)   If the sequestration or attachment of or execution on any
material part of Tenant's Personal Property essential to the conduct of Tenant's
business occurs, and Tenant fails to obtain a return or release of such Personal
Property within thirty (30) days thereafter, or prior to sale pursuant to such
sequestration, attachment or levy, whichever is earlier;

               (vi)  If Tenant shall have abandoned the Premises and failed to
pay Rent when due; or

               (vii) If a court makes or enters any decree or order other than
under the bankruptcy laws of the United States adjudging Tenant to be insolvent;
or approving as properly filed a petition seeking reorganization of Tenant; or
directing the winding up or liquidation of Tenant and such decree or order shall
have continued for a period of thirty (30) days.

          B.   Remedies.  Upon a default, Landlord shall have the following
               --------                                                    
remedies, in addition to all other rights and remedies provided by law or
otherwise provided in this Lease, to which Landlord may resort cumulatively or
in the alternative:

               (i)   Landlord may continue this Lease in full force and effect,
and this Lease shall continue in full force and effect as long as Landlord does
not terminate this Lease, and Landlord shall have the right to collect Rent when
due.

               (ii)  Landlord may terminate Tenant's right to possession of the
Premises at any time by giving written notice to that effect, and relet the
Premises or any part thereof. Reletting may be for a period shorter or longer
than the remaining term of this Lease.  No act by Landlord other than giving
written notice to Tenant shall terminate this Lease.  Acts of maintenance,

                                      -22-
<PAGE>
 
efforts to relet the Premises or the appointment of a receiver on Landlord's
initiative to protect Landlord's interest under this Lease shall not constitute
a termination of Tenant's right to possession. On termination, Landlord has the
right to remove all Tenant's Personal Property and store same at Tenant's cost
and to recover from Tenant as damages:

               (a) The worth at the time of award of unpaid Rent and other sums
due and payable which had been earned at the time of termination; plus

               (b) The worth at the time of award of the amount by which the
unpaid Rent and other sums due and payable which would have been payable after
termination until the time of award exceeds the amount of such Rent loss that
Tenant proves could have been reasonably avoided; plus

               (c) The worth at the time of award of the amount by which the
unpaid Rent and other sums due and payable for the balance of the Term after the
time of award exceeds the amount of such Rent loss that Tenant proves could be
reasonably avoided; plus

               (d) Any other amount necessary to compensate Landlord for all the
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease, or which, in the ordinary course of things, would be likely to
result therefrom, including, without limitation, any costs or expenses incurred
by Landlord:  (i) in retaking possession of the Premises; (ii) in maintaining,
repairing,  or cleaning the Premises or any portion thereof, including such acts
for reletting to a new tenant or tenants; (iii) for leasing commissions; or (iv)
for any other reasonable costs necessary or appropriate to relet the Premises;
plus

               (e) At Landlord's election, such other amounts in addition to or
in lieu of the foregoing as may be permitted from time to time by the Laws of
the State of California.

     The "worth at the time of award" of the amounts referred to in Paragraphs
26.B.(ii)(a) and 26.B.(ii)(b) is computed by allowing interest at the Interest
Rate on the unpaid rent and other sums due and payable from the termination date
through the date of award. The "worth at the time of award" of the amount
referred to in Paragraph 26.B.(ii)(c) is computed by discounting such amount at
the discount rate of the Federal Reserve Bank of San Francisco at the time of
award plus one percent (1%).

          (iii) If the Premises have been abandoned by Tenant or this
Lease has been terminated, Landlord may re-enter the Premises and remove all
property from the Premises; such property may be removed and stored in a public
warehouse or elsewhere at the cost of and for the account of Tenant.

     C.   Landlord's Default. Landlord shall not be deemed to be in default in
the performance of any obligation required to be performed by it hereunder
unless and until it has failed to perform such obligation within thirty (30)
days after receipt of written notice by Tenant to Landlord specifying the nature
of such default; provided, however, that if the nature of Landlord's obligation
is such that more than thirty (30) days are required for its performance, then
Landlord 

                                      -23-
<PAGE>
 
shall not be deemed to be in default if it shall commence such performance
within such thirty (30) day period and thereafter diligently prosecute the same
to completion.

     27.  Subordination.
          ------------- 

          This Lease is subject and subordinate to any ground and underlying
leases and any first mortgages and first deeds of trust (collectively
"Encumbrances") which may now affect the Premises and to all renewals,
modifications, consolidations, replacements and extensions thereof; provided,
however, if the holder or holders of any such Encumbrance ("Holder") shall
require this Lease be prior and superior to such Encumbrance, within ten (10)
days of written request of Landlord to Tenant, Tenant shall execute, have
acknowledged and deliver any and all reasonable documents or instruments, in
substantially the form presented to Tenant, which Landlord or Holder deems
necessary or desirable for such purposes. Landlord shall have the right to cause
this Lease to be and become and remain subject and subordinate to any and all
Encumbrances which are now or may hereafter be executed covering the Premises or
any renewals, modifications, consolidations, replacements or extensions thereof,
for the full amount of all advances made or to be made thereunder and without
regard to the time or character of such advances, together with interest thereon
and subject to all the terms and provisions thereof; provided only, that in the
event of termination of any such lease or upon the foreclosure of any such
mortgage or deed of trust, so long as Tenant is not in default beyond any notice
and applicable cure period, Holder agrees to recognize Tenant's rights under
this Lease as long as Tenant shall pay the Rent and observe and perform all the
provisions of this Lease to be observed and performed by Tenant.  Within ten
(10) days after Landlord's written request, Tenant shall execute any and all
reasonable documents required by Landlord or the Holder to make this Lease
subordinate to any lien of the Encumbrance.
 
          Notwithstanding anything to the contrary set forth in this paragraph,
Tenant hereby attorns and agrees to attorn to any entity purchasing or otherwise
acquiring the Premises at any sale or other proceeding or pursuant to the
exercise of any other rights, powers or remedies under such Encumbrance provided
such entity agrees to recognize all of Tenant's rights under this Lease in
writing.

          Prior to the Commencement Date, or following the Commencement Date if
Landlord refinances any Encumbrance or places any new Encumbrance on the
Premises which the Holder thereof desires to be prior to this Lease, Landlord
shall obtain from any Holder of any Encumbrance a written agreement, in form
reasonably acceptable to Tenant, providing for the non-disturbance and
recognition of Tenant's rights and interests under this Lease in the event of a
foreclosure or termination of the Holder's Encumbrance.

      28. Notices.
          ------- 

          Any notice or demand required or desired to be given under this Lease
shall be in writing and shall be personally served or in lieu of personal
service may be given by mail.  If given by mail, such notice shall be deemed to
have been given when seventy-two (72) hours have elapsed from the time when such
notice was deposited in the United States mail, registered or certified, and
postage prepaid, addressed to the party to be served.  At the date of execution
of this Lease, the 

                                      -24-
<PAGE>
 
addresses of Landlord and Tenant are as set forth in Paragraph 1. After the
Commencement Date, the address of Tenant shall be the address of the Premises.
Either party may change its address by giving notice of same in accordance with
this paragraph.

      29. Attorneys' Fees.
          --------------- 

          If either party brings any action or legal proceeding for damages for
an alleged breach of any provision of this Lease, to recover rent, or other sums
due, to terminate the tenancy of the Premises or to enforce, protect or
establish any term, condition or covenant of this Lease or right of either
party, the prevailing party in such action or proceeding shall be entitled to
recover its reasonable attorneys' fees (including attorneys' fees on appeal, and
costs and expenses incurred in out-of-court negotiations, workouts and/or
settlements or in seeking relief from stay or otherwise seeking to protect its
rights in any bankruptcy proceeding) and all reasonable costs (including costs
of consultants and experts) incurred, which shall be payable whether or not such
action is prosecuted to judgment.  In addition, the prevailing party shall be
entitled to its reasonable attorneys' fees, costs and expenses incurred in post-
judgment proceedings to collect and enforce a judgment.  This provision is
separate and several and shall survive the merger of this Lease into any
judgment on this Lease.

      30. Estoppel Certificates.
          --------------------- 

          Tenant shall within twenty (20) days following written request by
Landlord:

          (i)  Execute and deliver to Landlord an estoppel certificate, in the
form prepared by Landlord  (a) certifying that this Lease is unmodified and in
full force and effect or, if modified, stating the nature of such modification
and certifying that this Lease, as so modified, is in full force and effect and
the date to which the Rent and other charges are paid in advance, if any, and
(b) acknowledging that there are not, to Tenant's knowledge, any uncured
defaults on the part of Landlord, or, if there are uncured defaults on the part
of the Landlord, stating the nature of such uncured defaults, and (c) evidencing
the status of the Lease as may be required either by a lender making a loan to
Landlord to be secured by deed of trust or mortgage covering the Premises or a
purchaser of the Premises from Landlord.  Tenant's failure to deliver an
estoppel certificate within twenty (20) days after delivery of Landlord's
written request therefor shall be a breach of this Lease and shall be conclusive
upon Tenant (a) that this Lease is in full force and effect, without
modification except as may be represented by Landlord, (b) that there are now no
uncured defaults in Landlord's performance and (c) that no Rent has been paid in
advance.

          (ii) Deliver to Landlord the current financial statements of Tenant,
and financial statements of the two (2) years prior to the current financial
statements year, with an opinion of a certified public accountant, including a
balance sheet and profit and loss statement for the most recent prior year, all
prepared in accordance with generally accepted accounting principles
consistently applied.  All financial statements delivered by Tenant to Landlord
shall be held in strict confidence by Landlord (and Landlord's lender or any
prospective purchaser of the Premises requiring such financial statements) and
shall be used by Landlord, Landlord's lender or such prospective purchaser only
to evaluate Tenant's financial condition in connection with this Lease.

                                      -25-
<PAGE>
 
      31. Transfer of the Premises by Landlord.
          ------------------------------------ 

          In the event of any conveyance of the Premises and assignment by
Landlord of this Lease, Landlord shall be and is hereby entirely released from
all liability under any and all of its covenants and obligations contained in or
derived from this Lease occurring after the date of such conveyance and
assignment (but excluding any obligations or liabilities which arose prior to
the date of such transfer) and, with respect to the Security Deposit, shall be
released of its obligations with respect thereto so long as Landlord transfers
the Security Deposit to the transferee in accordance with California Civil Code
Section 1950.7.   Tenant agrees to attorn to such transferee provided such
transferee assumes Landlord's obligations under this Lease in writing for the
benefit of Tenant.

      32. Landlord's Right to Perform Tenant's Covenants.
          ---------------------------------------------- 

          If Tenant shall at any time fail to make any payment or perform any
other act on its part to be made or performed under this Lease, Landlord may,
but shall not be obligated to and without waiving or releasing Tenant from any
obligation of Tenant under this Lease, make such payment or perform such other
act to the extent Landlord may deem desirable, and in connection therewith, pay
expenses and employ counsel, but only if Tenant has failed to make such payment
or perform such obligation within thirty (30) days after written notice from
Landlord specifying the payment to be made or the obligation to be performed.
All reasonable sums so paid by Landlord and all penalties, interest and costs in
connection therewith shall be due and payable by Tenant on the next day after
written notice to Tenant of any such payment by Landlord, together with interest
thereon at the Interest Rate from such date to the date of payment by Tenant to
Landlord, plus collection costs and attorneys' fees.  Landlord shall have the
same rights and remedies for the nonpayment thereof as in the case of default in
the payment of Rent.

      33. Tenant's Remedy.
          --------------- 

          If, as a consequence of a default by Landlord under this Lease, Tenant
recovers a money judgment against Landlord, such judgment shall be satisfied
only out of the proceeds of sale received upon execution of such judgment and
levied thereon against the right, title and interest of Landlord in the Premises
and out of Rent or other income from such property received by Landlord or out
of consideration received by Landlord from the sale or other disposition of all
or any part of Landlord's right, title or interest in the Premises, and neither
Landlord nor Landlord's Agents shall be liable for any deficiency.

      34. Mortgagee Protection.
          -------------------- 

          If Landlord defaults under this Lease, Tenant will notify any
beneficiary of a first deed of trust or mortgagee of a first mortgage covering
the Premises of which Tenant has received written notice, including its address.
Such beneficiary or mortgagee shall have thirty (30) days after receipt of such
notice to cure the default specified therein; provided, however, that if the
nature of the default is such that more than thirty (30) days are reasonably
required to cure the default, such beneficiary or mortgagee shall have such
additional time as is reasonably necessary to cure such 

                                      -26-
<PAGE>
 
default so long as such beneficiary or mortgagee commences to cure the default
within such 30-day period and thereafter diligently prosecute such cure to
completion.

      35. Brokers.
          ------- 

          Tenant warrants and represents that it has had no dealings with any
real estate broker or agent in connection with the negotiation of this Lease,
except for Bristol Commercial Brokerage and CPS, The Commercial Property
Services Company and that it knows of no other real estate broker or agent who
is or might be entitled to a commission in connection with this Lease.  Tenant
and Landlord shall each  indemnify, defend and hold  each other harmless from
and against any and all liabilities or expenses, including reasonable attorneys'
fees and costs, arising out of or in connection with claims for commissions or
fees made by any other broker or individual  who represented or claims to have
represented the indemnifying party.  Landlord shall pay to CPS, The Commercial
Property Services Company, pursuant to a separate written agreement, any
commission due in connection with this Lease.

      36. Acceptance.
          ---------- 

          This Lease shall only become effective and binding upon full execution
hereof by Landlord and delivery of a signed copy to Tenant.  Neither party shall
record this Lease nor a short form memorandum thereof.

      37. Parking.
          ------- 

          Tenant shall have the exclusive right to use the Premises' parking
facilities upon such reasonable terms and conditions as may from time to time be
established by Landlord.

      38. Option to Extend.
          ---------------- 

          A.   Option Periods.  Provided that Tenant is not in default of any
               --------------                                                
material obligation hereunder beyond any applicable notice and cure or grace
period granted to Tenant by this Lease, either at the time of exercise or at the
time the extended Term commences, Tenant shall have the option to extend the
initial seven (7) year Term of this Lease for two (2) additional periods of
three (3) years each (each, an"Option Period") on the same terms, covenants and
conditions provided herein, except that upon such renewal the Monthly Rent due
hereunder shall be determined pursuant to Paragraph 38.B.  Tenant shall exercise
its option by giving Landlord written notice ("Option Notice") at least one
hundred twenty (120) days but not more than one hundred eighty (180) days prior
to the expiration of the initial Term of this Lease or the first Option Period,
as applicable.

          B.   Option Period Monthly Rent.  The Monthly Rent for each Option
               --------------------------                                   
Period shall be determined as follows:

               (i)   The parties shall have thirty (30) days after Landlord
receives the Option Notice within which to agree on the Monthly Rent for the
first year of the Option Period based upon the then fair market rental value of
the Premises as defined in Paragraph 38.B.(ii). If the

                                      -27-
<PAGE>
 
parties agree on the Monthly Rent for the first year of the Option Period within
thirty (30) days, they shall immediately execute an amendment to this Lease
stating the Monthly Rent for the first year of the Option Period and the
increases in Monthly Rent during such Option Period which shall be calculated as
provided in Paragraph 38.C. If the parties are unable to agree on the Monthly
Rent for the first year of the Option Period within thirty (30) days, then, the
Monthly Rent for the first year of the Option Period shall be the then current
fair market rental value of the Premises as determined in accordance with
Paragraph 38.B.(iii).

               (ii)  The "then fair market rental value of the Premises" shall
be defined to mean the fair market rental value of the Premises as of the
commencement of the Option Period, taking into consideration Tenant's obligation
to pay additional rent and expenses, the uses permitted under this Lease, the
quality, size, design, age and location of the Premises, the rent for comparable
buildings located in Sunnyvale, including any economic incentives such as free
rent and tenant improvement allowances. In no event shall the fair market
monthly rental value of the Premises for the first year of the Option Period be
less than the Monthly Rent last payable under the Lease.

               (iii)  Within thirty (30) days after the expiration of the thirty
(30) day period set forth in Paragraph 38.B.(i), each party, at its cost and by
giving notice to the other party, shall appoint a real estate appraiser with at
least five (5) years' full-time commercial appraisal experience in the area in
which the Premises are located to appraise and set the Monthly Rent. If a party
does not appoint an appraiser within such 30-day period, the single appraiser
appointed shall be the sole appraiser and shall set the Monthly Rent. If the two
(2) appraisers are appointed by the parties as stated in this paragraph, they
shall meet promptly and attempt to set the Monthly Rent. If they are unable to
agree within thirty (30) days after the second appraiser has been appointed,
they shall attempt to elect a third appraiser meeting the qualifications stated
in this paragraph within fifteen (15) days after the last day the two (2)
appraisers are given to set the Monthly Rent. If they are unable to agree on the
third appraiser, either of the parties to this Lease, by giving ten (10) days'
notice to the other party, can apply to the then Presiding Judge of the Santa
Clara County Superior Court, for the selection of a third appraiser who meets
the qualifications stated in this paragraph. Each of the parties shall bear one-
half ( 1/2) of the cost of appointing the third appraiser and of paying the
third appraiser's fee. The third appraiser, however selected, shall be a person
who has not previously acted in any capacity for either party.

          Within thirty (30) days after the selection of the third appraiser, a
majority of the appraisers shall set the Monthly Rent.  If a majority of the
appraisers are unable to set the Monthly Rent within the stipulated period of
time, the three (3) appraisals for either unresolved item shall be added
together and their total divided by three (3); the resulting quotient shall be
the Monthly Rent.  If, however, the low appraisal and/or the high appraisal
are/is more than ten percent (10%) lower and/or higher than the middle
appraisal, the low appraisal and/or the high appraisal shall be disregarded.  If
only one appraisal is disregarded, the remaining two (2) appraisals shall be
added together and their total divided by two (2); the resulting quotient shall
be the Monthly Rent.  If both the low appraisal and the high appraisal are
disregarded as stated in this paragraph, then only the middle appraisal shall be
used as the result of the appraisal.  After the Monthly Rent has been set, the
appraisers shall immediately notify the parties and the parties shall amend this
Lease to set forth such amount.

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

          In connection with the Demolition Work, the Exterior ADA Work, the
Seismic Work and the Tenant Improvements to be performed or installed in the

          1.   Demolition, Exterior ADA Work and Seismic Work. In addition, to

The cost of the  Demolition Work, the Exterior ADA Work and the Seismic Work

the right to review and approve the scope of the Demolition Work, the Exterior
ADA Work and the Seismic Work and to approve the contractor or contractors
selected by Tenant to perform the  Demolition Work, the Exterior ADA Work and
the Seismic Work, which approvals shall not be unreasonably withheld or delayed.

          2.   Plans and Specifications.
               ------------------------ 

               (a) Exterior ADA Work and Seismic Work.  Tenant shall retain a
                   ----------------------------------                        
licensed architect reasonably acceptable to Landlord for the completion of final

after Landlord's receipt of the Seismic Plans and the Exterior ADA Plans,
Landlord shall notify Tenant of Landlord's approval or disapproval thereof,
specifying in reasonable detail the basis for Landlord's disapproval, if
applicable.   Landlord shall not unreasonably withhold or delay its consent to
the Exterior ADA Plans or the Seismic Plans.  If Landlord fails to notify Tenant
of its approval or disapproval, specifying in reasonable detail the basis for
any disapproval,  within such 5-day period, Tenant may again request approval of
the Exterior ADA Plans and/or the Seismic Plans, as applicable, in writing.  If
Landlord fails to notify Tenant of Landlord's approval or disapproval of the
applicable plans within three (3) business days after Landlord's receipt of
Tenant's second notice, then Landlord shall be deemed to have approved the
applicable plans.  If Landlord reasonably disapproves the Exterior ADA Plans

Landlord's review and approval within fifteen (15) business days thereafter.
Landlord shall have three (3) business days after receipt of the revised plans

Seismic Plans and/or the approved Exterior ADA Plans shall be made by Tenant
unless approved in writing by Landlord, which approval shall not be unreasonably
withheld or delayed. If any revisions to the Exterior ADA Plans and/or the
Seismic Plans are required by any governmental agency to comply with applicable
Laws or to obtain any necessary permits, Landlord shall consent to such
revisions.

          (b) Tenant Improvements.  Landlord hereby approves Tenant's

disapproval thereof, specifying in reasonable detail the basis for Landlord's
disapproval, if applicable.  Tenant shall retain a licensed architect for the
completion of final working architectural and engineering plans and
specifications for the interior improvements based upon the approved space plan
("Tenant Improvement Plans").  Landlord hereby approves of Malesardi Design

any disapproval, within such 5-day period, Tenant may again request approval of
the Tenant Improvement Plans in writing.  If Landlord fails to notify Tenant of
Landlord's approval or disapproval of the Tenant Improvement Plans within three
(3) business days after Landlord's receipt of Tenant's second notice, then
Landlord shall be deemed to have approved the Tenant Improvement Plans.  If
Landlord reasonably disapproves the Tenant Improvement Plans, Tenant shall re-
submit revised plans to Landlord for Landlord's review and approval within

Plans shall be made by Tenant unless approved in writing by Landlord, which
approval shall not be unreasonably withheld.  If any revisions to the Tenant
Improvement Plans are required by any governmental agency to comply with
applicable Laws or to obtain any necessary permits, Landlord shall consent to
such revisions.

Plans, the Seismic Plans and the Tenant Improvement Plans shall be for
Landlord's sole purpose and shall not imply Landlord's review of the same, nor
obligate Landlord to review the same, for quality, design, compliance with Laws
or other like matters.  Accordingly, notwithstanding that the Exterior ADA
Plans, Seismic Plans and/or Tenant Improvement Plans are reviewed by Landlord or
its space planner, architect, engineers or consultants, Landlord shall have no
liability whatsoever in connection therewith and shall not be responsible for
any omissions or errors contained in the Exterior ADA Plans, Seismic Plans
and/or Tenant Improvement Plans.

reasonably approved by Landlord for each of the Demolition Work, the Exterior
ADA Work and the Seismic Work; (iii) the general contractor(s) selected by
Tenant for completion of the Demolition Work, the Exterior ADA Work and the
Seismic Work shall be subject to Landlord's reasonable approval; (iv) any
architectural and engineering fees incurred by Tenant in connection with the
Demolition Work, the Exterior ADA Work, and the Seismic Work shall be paid by

Fifty Thousand and no/100ths Dollars ($50,000.00) for completion of the
Demolition Work, (B) One Thousand Nine Hundred Forty and no/100ths Dollars
($1,940.00) for completion of the Exterior ADA Work, and (C) Twenty-Five

               (b)  The cost of the Demolition Work, the Exterior ADA Work and
the Seismic Work shall be paid by Landlord on a progress payment basis within

               (c)  If Landlord fails to make any progress payment to Tenant in

within such 10-day period, then Tenant may again request payment of the
applicable costs in writing.  If Landlord fails to pay any such costs within
five (5) business days after receipt of Tenant's second request for payment,
and Landlord's failure to pay such costs is not due to Tenant's failure to
submit any of the information required under Paragraph 6(b), then Tenant may
stop construction of all work and the Commencement Date of this Lease, and
Tenant's obligation to pay Rent or Landlord's out-of-pocket costs, as
applicable, shall be extended by one (1) day for each day that Landlord fails to
make the required progress payment.  If Landlord fails to make any progress
payment within sixty (60) days after Tenant's request therefor and Landlord's
failure to pay such costs is not due to Tenant's failure to submit any of the
information required under Paragraph 6(b), then Landlord shall be in breach of
this Lease.  In such event, Tenant shall be entitled to terminate this Lease
and/or sue Landlord for all damages proximately caused by such breach,
including, without limitation, all amounts owed under any construction contract
for the Demolition Work, the Exterior ADA Work, the Seismic Work and the Tenant
Improvements.

                           ARTISAN COMPONENTS, INC.

                              Severance Agreement


     This Agreement is made by and between Artisan Components, Inc. (the
"Company") and Robert Selvi ("Executive") as of the date set forth below.

     WHEREAS, the Company has employed Executive as the Company's Chief
Financial Officer, effective as of June 20, 1997, and

     WHEREAS, the Company and the Executive understand  and acknowledge that
Executive's employment with the Company constitutes "at-will" employment, and
that the employment relationship may be terminated at any time, with or without
good cause or for any or no cause, at the option either of the Company or the
Executive,

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

     1.   Termination of Employment.  If Executive's employment with the Company
          -------------------------                                             
terminates other than voluntarily (which shall include a "Constructive
Termination" as defined below) or for "Cause" (as defined below), then (i)
Executive shall be entitled to receive as severance pay (less applicable
withholding taxes) a continuation of his base salary, as then in effect, for a
period of six (6) months, plus any targeted bonus amount pro rated for such six
(6) month period as determined by the Board of Directors of the Company and paid
ratably over such six (6) month period, and (ii) Executive's option to purchase
503,386 shares of Common Stock, shall continue to vest for a period of 18 months
following Executive's date of termination.  For this purpose, "Constructive
Termination" is defined as (i) a material reduction in salary or benefits, (ii)
a material change in responsibilities from those of the Chief Financial Officer
of the Company, (iii) a requirement to relocate, except for office relocation
that would not increase the Executive's current one-way commute distance by more
than twenty-five (25) miles or (iv) subjection of Executive to unreasonable
working conditions, such as violation of Executive's civil rights, defamation of
Executive, intentional infliction of emotional distress, coercion to condone,
tolerate or participate in illegal or immoral acts, or similar conditions.  In
the event of a Constructive Termination, the Company will be deemed to have
involuntarily terminated the Executive even if the Executive tenders his
resignation to the Company.  For this purpose, "Cause" is defined as (i) an act
of dishonesty made by Executive in connection with Executive's responsibilities
as an employee and intended to result in Executive's substantial personal
enrichment, (ii) Executive's conviction of a felony, (iii) a willful act by
Executive which constitutes gross misconduct and which is injurious to the
Company, or (iv) Executive's continued substantial violations of his employment
duties which are demonstrably willful and deliberate on Executive's part after
Executive has received a written demand for performance from the Company which
specifically sets forth the factual basis for the Company's belief that
Executive has not substantially performed his duties.

     2.   Termination Incident to an Acquisition of the Company.
          ----------------------------------------------------- 
Notwithstanding Section 1 above, in the event of a change of control of the
Company, followed within six (6) months thereafter by the Constructive
Termination or involuntary termination of Executive's employment with the
Company or its successor entity without Cause, (i) Executive shall be entitled
to receive a cash payment of 
<PAGE>
 
severance pay (less applicable withholding taxes) representing an amount equal
to six months at a rate equal to his base salary rate as then in effect, plus
any targeted bonus amount pro rated for such six (6) month period as determined
by the Board of Directors of the Company, and (ii) Executive's option to
purchase 503,386 shares of Common Stock shall become 100% vested. For this
purpose, "change of control of the Company" is defined as:
 
     (a)  Any "person" (as such term is used in Sections 13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended) is or becomes the "beneficial
owner" (as defined in Rule 13d-3 under said Act), directly or indirectly, of
securities of the Company representing 50% or more of the total voting power
represented by the Company's then outstanding voting securities; or

     (b)  A change in the composition of the Board of Directors of the Company
occurring within a two-year period, as a result of which fewer than  a majority
of the directors are Incumbent Directors. "Incumbent Directors" shall mean
directors who either (A) are directors of the Company as of the date hereof, or
(B) are elected, or nominated for election, to the Board of Directors of the
Company with the affirmative votes of at least a majority of the Incumbent
Directors at the time of such election or nomination (but shall not include an
individual whose election or nomination is in connection with an actual or
threatened proxy contest relating to the election of directors to the Company);
or

     (c)  The date of the consummation of a merger or consolidation of the
Company with any other corporation that has been approved by the stockholders of
the Company, other than a merger or consolidation which would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) at least fifty percent (50%) of
the total voting power represented by the voting securities of the Company or
such surviving entity outstanding immediately after such merger or
consolidation, or the stockholders of the Company approve a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all the Company's assets.

     3.   Enforcement.  In the event of any action to enforce the terms of this
          -----------                                                          
Agreement, the prevailing party in such action shall be entitled to such party's
reasonable costs and expenses of enforcement including, without limitation,
reasonable attorneys' fees.

     4.   Entire Agreement.  This Agreement, the Stock Option Plan, the Option
          ----------------                                                    
Agreement, and the Proprietary Information Agreement of even date herewith
represent the entire agreement and understanding between the Company and
Executive concerning Executive's employment relationship with the Company,
supersedes and replaces any and all prior agreements and understandings
concerning Executive's employment relationship with the Company.

     5.   No Oral Modification, Cancellation or Discharge.  This Agreement may
          -----------------------------------------------                     
only be amended, canceled or discharged in writing signed by Executive and the
Company.

     6.   Governing Law.  This Agreement shall be governed by the laws of the
          -------------                                                      
State of California.
<PAGE>
 
     7.   Effective Date.  This Agreement is effective immediately after it has
          --------------                                                       
been signed.

     8.   Acknowledgment.  Executive acknowledges that he has had the
          --------------                                             
opportunity to discuss this matter with and obtain advice from his private
attorney, has had sufficient time to, and has carefully read and fully
understands all the provisions of this Agreement, and is knowingly and
voluntarily entering into this Agreement.

     IN WITNESS WHEREOF, the undersigned have executed this Agreement as of June
20, 1997.

[ARTISAN COMPONENTS LOGO]

July 31, 1996

Mr. Larry Fagg

Dear Larry:

Artisan Components, Inc. ("Artisan") is pleased to offer you the position of
Vice President of Worldwide Sales reporting directly to me. Your starting base
salary will be $140,000 per year with an opportunity to earn an additional
$100,000 in sales commissions at 100% of your annual fiscal year target.  For
the first six months of your employment, Artisan will advance up to 100% of your
monthly commissions at target (i.e. up to $9,167 per month) at your request.  Up
to half of the total amount advanced to you will be recoverable by Artisan
should you fall short of reaching you annual sales target.

Since we believe you will be making a significant contribution to the success of
Artisan Components, we are offering you an option of 218,863 shares of Artisan
common stock.  The exercise price of your option will be fair market value as
determined by the board of directors on the date the option is granted. This
stock vests ratably over a four-year period from your date of hire, however you
must work for the company for one year before any stock vests to you.

In the event of a "Change of Control" which is defined as the acceptance of
Artisan of any offer from an entity to acquire any shares of voting stock which
would result in such entity owning more than 50% of the voting stock of Artisan
then outstanding that results in the termination of your employment with
Artisan, you will receive a severance payment equal to six months of base salary
and commissions at target.  You will also be allowed to continue to participate
in Artisan's benefit programs for a period of six months after the effective
date of your termination at no cost to you.  In addition, one half of your
remaining unvested stock options will immediately vest from the effective date
of your termination.

We offer a comprehensive benefit program and you will be eligible to participate
in most of it on your date of hire.  These benefits are summarized on the
attached Benefits at a Glance form, and will be explained to you in detail once
you are on board.  We are looking forward to having you join us.

Best regards,

/s/ Mark Templeton
Mark Templeton,
President

Please acknowledge your acceptance by signing and returning one copy of this
letter.
