  Artisan is a leading developer of high performance, low power and high

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

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 $760 million in 1997 to
approximately $2.6 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"), Hitachi, Ltd. ("Hitachi"), NEC Electronics, Inc. ("NEC"), Newport
Wafer Fab, Ltd. ("Newport"), OKI Electric Industry Co., Ltd. ("OKI"), SGS-
THOMSON MICROELECTRONICS S.r.l. ("SGS-THOMSON"), Siemens AG ("Siemens"),
Taiwan Semiconductor Manufacturing Corporation ("TSMC"), 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 reincorporated in Delaware in January 1998. The Company's
principal executive offices are located at 1195 Bordeaux Drive, Sunnyvale,
California 94089, and its telephone number is (408) 734-5600.

                                 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 within the
meaning of Section 27A of the Securities Act of 1933, as amended (the
"Securities Act") and Section 21E of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"). 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 the completion period ranges from three to six
months, the revenue in any quarter is dependent
 
                                       5
<PAGE>
 
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. From
time to time, the Company experiences 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!"), Duet
Corporation ("Duet"), 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. For
example, the Company believes that Synopsys is developing and will shortly
introduce a product in the standard cell library area that is intended to
compete with the standard cell products of 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. The Company believes the introduction, as
opposed to the operation, of the royalty based business model has been a
limited success in that the majority of the Company's licensees, including all
new licensees with whom the Company has contracted since August 1996, have
agreed to a royalty based model. However, certain licensees, which have
previously contracted with the Company based on the older model, have resisted
conversion to a royalty based model. As a result, the Company believes that
until all of its customers have adopted the royalty based model, the
introduction of such model can only be described as a limited success. 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 due to the typical length of
time required for the Company to design a component for a customer and for
such customer to manufacture and bring to market a product incorporating such
component. 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. In the six month period ended
March 31, 1998, TSMC, OKI, SGS-THOMSON, NEC and Newport accounted for 13%,
13%, 12%, 12% and 11% 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
 
                                       8
<PAGE>
 
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 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%, 94% and 98% of revenue in fiscal 1995, 1996 and 1997 and the six
month period ended March 31, 1998, respectively. The Company expects that
memory products, in combination with standard cell products, will continue to
account for a substantial 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 and
 
                                       9
<PAGE>
 
the six month period ended March 31, 1998, revenue derived from customers
outside the United States, primarily in Asia and Europe, represented
approximately 55%, 47%, 67% and 74%, 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 experience fewer orders from international customers whose business is
based primarily on the less expensive currency. To date, the Company has not
experienced any negative impact as a result of the financial and stock market
dislocations that occurred in the Asian financial markets during 1997 and to
date in 1998; however, there can be no assurance that present or future
dislocations will not have a material adverse effect on the Company's
business, operating results and financial condition. 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
 
                                      10
<PAGE>
 
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."
 
  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 March 31, 1998, the Company grew from 28 to 74 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.
 
 
                                      11
<PAGE>
 
  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, 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."
 
  POTENTIAL VOLATILITY OF STOCK PRICE. The trading price of the Company's
Common Stock has in the past been and could in the future be subject to
significant fluctuations in response to quarterly variations in the Company's
results of operations, announcements regarding the
 
                                      12
<PAGE>
 
Company's product developments, announcements of technological innovations or
new products by the Company, its customers or competitors, release of reports
by securities analysts, changes in security analysts' recommendations,
developments or disputes concerning patents or proprietary rights or other
events. Also, at some future time, the Company's revenues and results of
operations may be below the expectations of public market securities analysts
or investors, resulting in significant fluctuations in the market price of the
Company's Common Stock. In addition, the securities markets have from time to
time experienced significant price and volume fluctuations which have
particularly affected the market prices for high technology companies and
which often are unrelated and disproportionate to the operating performance of
particular companies. These broad market fluctuations as well as general
economic, political and market conditions, may adversely affect the market
price of the Company's Common Stock. In the past, following periods of
volatility in the market price of a company's stock, securities class action
litigation has occurred against that company. Such litigation could result in
substantial costs and would at a minimum divert management's attention and
resources, which could have a material adverse effect on the Company's
business, financial condition and results of operations. Any adverse
determination in such litigation could also subject the company to significant
liabilities. See "Price Range of Common Stock."
 
  CONCENTRATION OF OWNERSHIP. The Company's founders, officers, directors and
their affiliates will, in the aggregate, beneficially own approximately 46.2%
of the Company's outstanding Common Stock following the completion of this
Offering (44.6% 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 and Selling Stockholders."
 
  CERTAIN ANTI-TAKEOVER PROVISIONS. The Board of Directors of the Company has
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 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 (i) restrictions under the Securities Act, (ii) lock-up agreements
executed by optionholders and substantially all stockholders of the Company in
connection with the Company's initial public offering in February 1998, which
agreements expire on August 1, 1998, (iii) lock-up agreements entered into by
Selling Stockholders who are current officers or founders in connection with
this Offering under which such Selling Stockholders have agreed not to sell or
otherwise dispose of any of their shares for a period of 180 days from the
date of this Prospectus and (iv) lock-up agreements entered into by officers
(who are not Selling Stockholders), directors and Selling Stockholders (other
than current founders and officers) in connection with this Offering under
which such persons have agreed not to sell or otherwise dispose of any of
their shares for a period of 90 days from the date of this Prospectus.
Assuming no exercise of the Underwriters' over-allotment option and no
exercise of outstanding options, there will be 13,266,411 shares of Common
Stock outstanding as of the date of this Prospectus, of which 6,631,411 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, (ii) approximately 621,429 shares will become
eligible for sale upon expiration of lock-up agreements on August 1, 1998,
(iii) approximately 2,457,321 shares will become eligible for sale 90 days
from the date of this Prospectus and (iv) approximately 3,552,661 shares will
become eligible for sale 180 days after the date of this Prospectus. After
this Offering, the holders of approximately 2,935,736 shares of Common Stock
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 majority of the net
proceeds has not been allocated to any specific purpose and the Company
reserves the right to reallocate that portion of the net proceeds of this
Offering that has specifically been allocated 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.

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 968,870 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$19.8 million (approximately $30.2 million if the Underwriters' over-allotment
option is exercised in full) at an assumed public offering price of $22.125
per share and after deducting the estimated underwriting discount and offering
expenses. The Company will not receive any proceeds from the sale of shares by
the Selling Stockholders.
 
  The Company ultimately expects to use the net proceeds from this Offering
for general corporate purposes. As of the date of this Prospectus, the Company
has no specific plans regarding the use 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.
 
                          PRICE RANGE OF COMMON STOCK
 
  The Company's Common Stock has been quoted on the Nasdaq National Market
under the symbol ARTI since the Company's initial public offering on February
2, 1998. Prior to such time, there was no public market for the Common Stock
of the Company. The following table sets forth for the periods indicated the
high and low sale prices per share of the Common Stock as reported on the

                    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

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 received under the terms of license
agreements with customers to provide 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 due to the typical length of
time required for the Company to design a component for a customer and for
such customer to manufacture and bring to market a product incorporating such
component. 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
 
                                      18
<PAGE>
 
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. In the six month period ended March 31, 1998, TSMC,
OKI, SGS-THOMSON, NEC and Newport accounted for 13%, 13%, 12%, 12% and 11% 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 and the six month
period ended March 31, 1998, revenue from customers outside the United States,
primarily in Asia and Europe, represented approximately 55%, 47%, 67% and 74%,
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%, 94%
and 98% of revenue in fiscal 1995, 1996 and 1997 and the six month period
ended March 31, 1998, respectively. The Company expects that memory products,
in combination with standard cell products, will continue to account for a
substantial 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
 
                                      19
<PAGE>
 
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."
 
  In connection with the grant of options for the purchase 96,200 shares of
Common Stock to employees during the period from December 1996 through March
1997, the Company recorded aggregate deferred compensation of approximately
$198,000, representing the difference between the deemed fair value of the
Common Stock and the option exercise price at the date of grant. Such deferred
compensation will be amortized over the vesting period relating to the
options, of which approximately $41,000 and approximately $24,000 have been
amortized during the year ended September 30, 1997 and the six month period
ended March 31, 1998, respectively, all of such amounts were recorded in
product development expenses. In addition, the amortization will result in
charges over the next 12 quarters aggregating approximately $12,000 per
quarter, all of which will be recorded in product development expenses.

SIX MONTHS ENDED MARCH 31, 1997 AND 1998
 
 Revenue
 
  Revenue increased by 124.7 % from $3.2 million in the six month period ended
March 31, 1997 to $7.1 million in the six month period ended March 31, 1998.
The growth in revenue in the first two quarters of fiscal 1998 as compared
with the same period in fiscal 1997 was primarily attributable to increased
licensing of the Company's memory and standard cell products, which more than
offset a decline in the sale of I/O products.
 
                                      20

 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 115.8% from $1.8 million in
the six month period ended March 31, 1997 to $3.8 million in the six month
period ended March 31, 1998. Engineering costs as a percentage of revenue
declined from 56.0% in the six month period ended March 31, 1997 to 53.8% for
the six month period ended March 31, 1998. The absolute dollar increase in
engineering costs in the first two quarters of fiscal 1998, as compared with
the same period in fiscal 1997, was due primarily to an increase in
engineering personnel and, to a lesser extent, purchases of computer
equipment, software tools and networking infrastructure and equipment and
legal costs associated with the Company's patent program.
 
    Cost of Revenue. Cost of revenue increased by 126.8% from $926,000 in the
  six month period ended March 31, 1997 to $2.1 million in the six month
  period ended March 31, 1998. Cost of revenue as a percentage of revenue was
  29.4% and 29.6% for the six month periods ended March 31, 1997 and 1998,
  respectively. The absolute dollar increase in cost of revenue in the first
  two quarters of fiscal 1998, as compared with the same period of fiscal
  1997, was due to increases in headcount and costs associated with
  delivering product to, and supporting, a growing customer base.
 
    Product Development Expenses. Product development expenses increased by
  103.8% from $841,000 in the six month period ended March 31, 1997 to $1.7
  million in the six month period ended March 31, 1998. Product development
  expenses as a percentage of revenue declined from 26.7% to 24.2% for the
  six month periods ended March 31, 1997 and 1998, respectively. The absolute
  dollar increase in product development expenses in the first two quarters
  of fiscal 1998, as compared with the same period in fiscal 1997, was
  attributable to an increase in engineering personnel and, to a lesser
  extent, purchases of computer equipment, software tools and networking
  infrastructure and equipment and legal costs associated with the Company's
  patent program.
 
    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 156% from $704,000 in the six month period ended
  March 31, 1997 to $1.8 million in the six month period ended March 31,
  1998. Sales and marketing expense as a percentage of revenue increased from
  22.3% for the six month period ended March 31, 1997 to 25.4% for the six
  month period ended March 31, 1998. The increase in absolute dollars in
  sales and marketing expenses in the first two quarters of fiscal 1998, as
  compared with the same period in fiscal 1997, was primarily attributable to
  increases in sales headcount and commissions expense to support an expanded
  customer coverage model and increases in marketing headcount and
  promotional activity.
 
    General and Administrative Expenses. General and administrative expenses
  increased by 78.2% from $501,000 in the six month period ended March 31,
  1997 to $893,000 in the six month period ended March 31, 1998. As a
  percentage of revenue, general and administrative expenses decreased from
  15.9% to 12.6% in the six month period ended March 31, 1997 and 1998,
  respectively. The absolute dollar increases in general and administrative
  expenses in the first two quarters of fiscal 1998, as compared with the
  same period in fiscal 1997, was primarily due to increases in general and
  administrative personnel and increases in professional services fees.
 
                                      21
<PAGE>
 
 Other Income
 
  Other income increased by 132.6% from $132,000 in the six month period ended
March 31, 1997 to $307,000 in the six month period ended March 31, 1998. Other
income as a percentage of revenue remained relatively constant at 4.2% and
4.3% for the six month periods ended March 31, 1997 and 1998, respectively.
The growth in other income in the first two quarters of fiscal 1998, as
compared with the same period in fiscal 1997, primarily reflects interest
income earned on the proceeds from the Company's initial public offering which
was completed in February 1998.
 
 Income Taxes
 
  The provision for income taxes was $109,000 and $289,000 in the six month
periods ended March 31, 1997 and 1998, respectively. The effective tax rate
decreased to 32.6% in the first two quarters of fiscal 1998, as compared with
34.6% in the first two quarters of fiscal 1997. The change in effective tax
rate for the respective periods was primarily due to the Company investing the
proceeds from its initial public offering in securities that are exempt from
federal taxation.
 
YEARS ENDED SEPTEMBER 30, 1995, 1996 AND 1997
 
 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 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 54.0% 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 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 and
  the decrease as a percentage of revenue was the result of revenue growth in
  excess of the growth in cost of revenue.
 
    Product Development Expenses. Product development expenses increased by
  3.4% from $1.0 million in fiscal 1995 to $1.1 million 1996 and by 81.0% to
  $2.0 million in fiscal 1997. Product development expenses as a percentage
  of revenue were 38.4%, 26.0% and 21.9% 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
 
                                      22
<PAGE>
 
  standard cell product. 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 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 in absolute
  dollars 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 increases in sales and marketing
  expenses as a percentage of revenues was due to expense growth in this
  category which exceeded the growth of revenue. 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. Absolute dollar increases in general and
  administrative expenses during these periods are the result of increases in
  headcount and in legal, accounting and other professional expenses. Changes
  in the percentage of revenues represented by general and administrative
  expenses were due to changes in the growth of revenues for the respective
  periods. 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.
 
 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 34.2%
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 and the first
two quarters of fiscal 1998. 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
<PAGE>
 
  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 and in the first two quarters of fiscal 1998. 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 and in the first quarter of fiscal 1998 as a result of
increased administrative efforts necessary to manage the Company's growth.
General and administrative expenses declined sequentially in the second
quarter of fiscal 1998 as the Company experienced a reduction in the costs
associated with professional services. 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 and in the first and second
quarters of fiscal 1998. 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 percentage of revenue represented by general and administrative
expenses in the future will depend largely 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. Other income increased in the first
quarter of fiscal 1998 primarily as a result of the generation of cash from
operations and the investment of such cash. The growth in other income in the
second quarter of fiscal 1998 primarily reflects interest income earned on the
proceeds from the Company's initial public offering which was completed in
February 1998.
 
  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, if any,
recognized in a given period.
 
                                      25

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 license revenue
received from inception to March 31, 1998, the net proceeds of $27.1 million
from its initial public offering of Common Stock in February 1998 and, to a
lesser extent, the proceeds of approximately $7.7 million from the sale of
Preferred Stock and a warrant.
 
  The Company's operating activities were essentially cash neutral in fiscal
1995, provided net cash of $566,000 in fiscal 1996, provided net cash of
$757,000 in fiscal 1997 and provided net cash of $1.0 million in the six month
period ended March 31, 1998. 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, $4.6
million and $27.8 million in fiscal 1995, 1996 and 1997 and the six month
period ended March 31, 1998, 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, $4.2
million and $27.3 million in fiscal 1995, 1996 and 1997 and the six month
period ended March 31, 1998, respectively. In fiscal 1996 and 1997, financing
activities consisted primarily of sales of Convertible Preferred Stock
partially offset, in 1996, by payments on the Company's line of credit. In the
six month period ended March 31, 1998, financing activities consisted
primarily of sales of the Company's Common Stock in its initial public
offering. See Notes 7 and 9 of Notes to Financial Statements.
 
  At March 31, 1998, the Company had cash, cash equivalents and current
marketable securities of $30.7 million. As of March 31, 1998, the Company had
retained earnings of $1.6 million and working capital of $31.9 million, net of
a short term component comprised of deferred revenue of $1.2 million. The
Company anticipates spending at least $765,000 for office lease payments and
approximately $2.5 million for capital expenditures over the next 12 months.
 
  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 and investment 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 has
no current plans, and is not currently negotiating, to obtain additional
financing following the completion of this Offering. 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.
 
                                      26

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."

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 $760 million in 1997 to
approximately $2.6 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
over 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
provides semiconductor manufacturers with reliable building blocks for future
generations of their complex IC designs. Artisan's ability to adapt and
customize 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 standardize 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 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,
 
                                      30
<PAGE>
 
the Company has licensed its products to many leading semiconductor
manufacturers including Chartered, Fujitsu, GEC Plessey, Hitachi, NEC,
Newport, OKI, SGS-THOMSON, Siemens, Toshiba, TSMC 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. All
of the new licensees with whom the Company has contracted since August 1996
have agreed to the Company's royalty based model. However, since certain
licensees which have previously contracted with the Company based on the older
model have resisted conversion to a royalty based model, the Company believes
that the introduction of such model can only be described as a limited
success. The Company currently generates revenue solely from license fees, but
the Company expects to recognize royalty revenue beginning in fiscal 1999 when
the Company's customers which have entered royalty based licenses are expected
to begin the manufacture and sale of products incorporating the Company's
components. 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 for use 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.
 
                                      31
<PAGE>
 
  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 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 0.25Mu 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 0.25Mu 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
 
                                      32
<PAGE>
 
value of its IC offerings to customers. SGS-THOMSON has used Artisan's
embedded memory products in more than 200 of its IC designs. SGS-THOMSON has
licensed Artisan's embedded memory products for seven different manufacturing
processes, including its 0.5Mu, 0.35Mu, 0.25Mu and 0.18Mu 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 0.5Mu, 0.35Mu and 0.25Mu 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 its advanced 3D graphics ICs. By
utilizing the Company's products, Fujitsu can accelerate its product
development and meet the needs of its graphics architecture. The ICs will be
built using Fujitsu's 0.25Mu 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 March 31, 1998, Artisan had 46 employees in the engineering
department. In fiscal 1995, 1996 and 1997 and the six month period ended March
31, 1998, total engineering costs were approximately $2.0 million, $2.4
million, $4.8 million and $3.8 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 requirements and that keep pace with new product introductions,
emerging manufacturing processes and other technological developments in the
semiconductor industry. The
 
                                      33
<PAGE>
 
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 over twenty 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.

   business of which was acquired by ATI in 1997.
+The Company is currently in the process of completing delivery of an initial

  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
 
                                      34
<PAGE>
 
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. In the six month period ended March 31, 1998, TSMC, OKI, SGS-
THOMSON, NEC and Newport accounted for 13%, 13%, 12%, 12% and 11% 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 in 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 March 31, 1998, the Company's sales and
marketing organization was comprised of 13 sales and five 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 and the six month
period ended March 31, 1998, revenue derived from customers outside the United
States, primarily in Asia and Europe, represented approximately 55%, 47%, 67%
and 74%, 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 competitors
denominate their sales in currencies that become relatively inexpensive in
comparison to the U.S. dollar, the
 
                                      35
<PAGE>
 
Company may experience fewer orders from international customers whose
business is based primarily on the less expensive currencies. To date, the
Company has not experienced any negative impact as a result of the financial
and stock market dislocations that occurred in the Asian financial markets
during 1997 and to date in 1998; however, there can be no assurance that
present or future dislocations will not have a material adverse effect on the
Company's business, operating results and financial condition. 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!, Duet,
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. For example, the
Company believes that Synopsys is developing and will shortly introduce a
product in the standard cell library area that is intended to compete with the
standard cell products of 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
 
                                      36
<PAGE>
 
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 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 March 31, 1998, the Company had applications for 14 patents on file with
the USPTO. To date, the USPTO has issued a notice of allowance with respect to
a patent relating to reducing power consumption of the Company's memory
products and a second patent relating to increasing the speed of the Company's
memory products. The Company expects that the USPTO will issue patents
relating to the notices of allowance within the next six months. There can be
no assurance, however, that such patents will actually be issued. As of March
31, 1998, the Company had no filings for foreign patents, but the Company
intends to file such foreign patent applications as appropriate in the future.
The Company has filed two applications under the Patent Cooperation Treaty
relating to two patents previously filed with the USPTO. 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
 
                                      37
<PAGE>
 
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 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 March 31, 1998, the Company had 74 fulltime employees. Of this total,
46 were in engineering, 18 were in sales and marketing and 10 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.

BOARD COMMITTEES
 
  The Company's Board of Directors has an Audit Committee and a Compensation
Committee. The Audit Committee is currently comprised of directors Lanza and
Harari. The Audit Committee's functions include: (i) recommending annually to
the Board of Directors the appointment of the independent public accountants
of the Company, (ii) reviewing the scope of the prospective annual audit and
reviewing the results thereof with the independent public accountants, (iii)
reviewing non-audit services of the independent public accountants, (iv)
reviewing compliance with the accounting and financial policies of the
Company, (v) reviewing the adequacy of the financial organization of the
Company, (vi) reviewing the adequacy of the Company's internal accounting
control system and its compliance with federal and state laws relating to
accounting practices and (vii) reviewing transactions with affiliated parties.
The Compensation Committee is currently comprised of directors Lanza and
Harari. The functions of the Compensation Committee include the review and
recommendation to the Board of Directors of the compensation and benefits of
all officers, directors and consultants of the Company and the review of
general policies relating to compensation and benefits of the Company's
employees. In addition, the charter of the Compensation Committee provides
that
 
                                      40
<PAGE>
 
upon the request of the Board of Directors, the Compensation Committee may
administer the Company's 1993 Plan and recommend and approve the grant of
options thereunder. The 1993 Plan is currently administered by the
Compensation Committee. The Company has no formal procedures in place to
review a transaction between a member of the Compensation Committee and the
Company. Given that the Compensation Committee is currently comprised of only
two directors, the Company anticipates that, in accordance with general
principles of corporate governance and Delaware corporation law, a transaction
with a member of the Compensation Committee or such member's affiliates would
be reviewed and approved by the Board of Directors with the interested
director abstaining from such review and approval.
 
DIRECTOR COMPENSATION
 
  Board of Directors members do not receive any cash fees for their service on
the Board of Directors or any committee of the Board of Directors, but they
are entitled to reimbursement of all reasonable out of pocket expenses
incurred in connection with their attendance at Board of Directors and Board
of Directors committee meetings. All Board of Directors members are eligible
to receive stock options pursuant to the discretionary option grant program in
effect under the 1993 Plan, and nonemployee directors receive stock options
pursuant to the automatic option grant program in effect under the Director
Plan. See "--Stock Plans." Pursuant to such automatic option grant program, on
February 6, 1998, each of Lucio L. Lanza and Dr. Eli Harari received an option
to purchase 25,000 shares of the Company's Common Stock at an exercise price
of $10.00. In March 1998, Dr. Harari received an option to purchase
10,000 shares of the Company's Common Stock at an exercise price of $16.4375
pursuant to the 1993 Plan in connection with Dr. Harari's agreement to provide
consulting services to the Company. The Company will pay Dr. Harari a nominal
fee with respect to such consulting services.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Compensation Committee is responsible for determining salaries,
incentives and other forms of compensation for directors, officers and other
employees of the Company and administers various incentive compensation and
benefit plans. Mr. Templeton intends to participate in the discussions of the
Compensation Committee regarding all officers' compensation other than his
own.
 
  No interlocking relationship exists between any member of the Company's
Compensation Committee and any member of any other company's board of
directors or compensation committee.
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS
 
  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.
Insofar as indemnification for liabilities arising under the Securities Act
may be permitted for directors, officers and controlling persons of the
Company pursuant to the provisions described herein, or otherwise, the Company
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.
 
 
                                      41
<PAGE>
 
  The Company's 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 Bylaws covers negligence and may cover gross
negligence on the part of indemnified parties. The Company's 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 Bylaws would permit indemnification.
 
  The Company has entered into agreements to indemnify its directors and
officers, in addition to indemnification provided for in the Company's Bylaws.
These agreements, among other things, provide for indemnification of the
Company's 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. On January 12, 1998, the Company granted options to purchase Common
    Stock at an exercise price of $7.70 per share, with the exception of
    Messrs. Gandhi and Lewis for whom the exercise price is $7.00 per share,
    to the following Named Executive Officers in the following amounts:
    100,000 shares to Mark R. Templeton, 50,000 shares to each of Scott T.
    Becker and Dhrumil Gandhi, 35,000 shares to Jeffrey A. Lewis and 20,000

(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

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 1993 Plan is currently being administered by the
Compensation Committee of the Board of Directors.
 
  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
 
                                      45
<PAGE>
 
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 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 March 31, 1998, 926,192 shares of Common Stock had been issued upon
the exercise of options granted under the 1993 Plan, options to purchase
2,211,708 shares of Common Stock at a weighted average exercise price of
$4.4828 per share were outstanding and 1,153,496 shares remained 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, is 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 is implemented in a series of
overlapping offering periods, each to be approximately 24 months in duration.
The initial offering period under the Purchase Plan began on February 2, 1998
and will continue until July 31, 2000. Following the initial offering period,
the offering periods under the Purchase Plan 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
 
                                      46
<PAGE>
 
than such fair market value on the start date of that offering period, then
all participants in that offering period will be automatically withdrawn from
such offering period and re-enrolled in the immediately following offering
period. The purchase price of the Common Stock under the Purchase Plan will be
equal to 85% of the lesser of the fair market value per share of Common Stock
on the start date of the offering period or on the 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 became effective upon
the effective date of the Company's initial public 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 provided for the grant of an initial option to purchase
25,000 shares to each nonemployee director of the Company upon the effective
date of the Company's initial public offering at a per share exercise price
equal to the initial public offering price. Each new nonemployee director
joining the Board of Directors 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 in February
2008, unless sooner terminated by the Board of Directors.
 
  As of March 31, 1998, no shares of Common Stock had been issued upon the
exercise of options granted under the Director Plan, options to purchase
50,000 shares of Common Stock
 
                                      47
<PAGE>
 
at a weighted average exercise price of $10.00 per share were outstanding and
150,000 shares remained available for future option grants under the Director
Plan.
 
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 $10,000 in calendar year 1998) 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 the sale or merger of
the Company with another entity, 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 ($86,400 based on Mr.
Selvi's current salary) 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. For purposes of Mr. Selvi's severance agreement, a
change in control is defined as (i) any person becoming the beneficial owner
of 50% or more of the total voting power of the Company's then outstanding
voting securities, (ii) a change in the composition of the Board of Directors
within a two year period such that a majority of the then current directors
are not directors as of the date of Mr. Selvi's agreement or nominated or
elected by a majority of such directors at the time of such nomination or
(iii) 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 at least 50% of the total voting power represented by the voting
securities of the Company or such
 
                                      48

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.
 
  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 the 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 the time of issuance of such shares.
Synopsys exercised the Warrant on February 6, 1998 for 50,000 shares of Common
Stock at $3.77 per share. The Warrant terminated with respect to such variable
amount of shares upon the closing of the Company's initial public offering.
 
  As of March 31, 1998, Synopsys beneficially owned 891,448 shares of Common
Stock (the "Synopsys Shares"). Synopsys has informed the Company that it has
entered into a forward sale arrangement, effective upon the closing of this
Offering, with respect to the Synopsys Shares with Deutsche Bank AG, London
Branch ("Deutsche Bank"), an affiliate of Deutsche Morgan Grenfell Inc. (the
lead Underwriter for this Offering, see "Underwriting"), under which Synopsys
will sell to Deutsche Bank all of the Synopsys Shares. See "Principal and
Selling Stockholders" and "Underwriting."
 
  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
 
                                      51
<PAGE>
 
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.
 
TRANSACTIONS WITH DANIEL I. RUBIN
 
  In connection with the termination of Daniel I. Rubin's employment with the
Company, the Company and Mr. Rubin, who was Vice President, Business
Development until April 15, 1998, entered into a separation agreement pursuant
to which Mr. Rubin will receive $86,400 to be paid over a period of six months
plus a lump sum of approximately $8,200 representing the approximate cost to
the Company of six months of the benefits received by Mr. Rubin and amounts
due to Mr. Rubin for benefits to which he was previously entitled.
 
  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.

SYNOPSYS SHARES
 
  Synopsys is the beneficial owner of the Synopsys Shares (891,448 shares of
Common Stock) representing approximately 7.2% of the outstanding Common Stock
of the Company as of March 31, 1998. Synopsys is also one of the Company's
primary competitors. See "Risk Factors--Competition."
 
  Synopsys has informed the Company that it has entered into a forward sale,
effective upon the closing of this Offering, of the Synopsys Shares with
Deutsche Bank. The forward sale involves the sale by Synopsys to Deutsche Bank
of the Synopsys Shares at a per share price equal to the price to the public
set forth on the cover page of this Prospectus less the underwriting discount.
The Synopsys Shares subject to the forward sale arrangement will be delivered
to Deutsche Bank and payment made therefor in approximately equal installments
on six quarterly settlement dates beginning June 15, 1998 and ending September
15, 1999. The forward sale arrangement provides for acceleration under certain
circumstances, including termination of the borrowing arrangement described
below.
 
  Deutsche Bank has informed the Company that it will hedge its forward
purchase of the Synopsys Shares by selling short through Deutsche Morgan
Grenfell Inc. an equivalent number of shares of Common Stock as part of this
Offering. Synopsys has agreed to lend to Deutsche Bank the Synopsys Shares
prior to the closing of this Offering so that Deutsche Bank can use the
borrowed shares to effect its short sale. Deutsche Bank's short sale, and the
accompanying borrowing arrangement with Synopsys, are being effected pursuant
to the Registration Statement, and Deutsche Morgan Grenfell Inc. will deliver
this Prospectus in connection with any sales of Shares effected on Deutsche
Bank's behalf.
 
  Assuming that all the shares of Common Stock intended to be sold by Synopsys
pursuant to its forward sale arrangement with Deutsche Bank are sold, and
assuming no other acquisition of the Company's Common Stock by Synopsys,
Synopsys will no longer own any shares of the Company's Common Stock as of the
final settlement date under the forward sale arrangement.

                         DESCRIPTION OF CAPITAL STOCK
 
  The Company is 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 March 31, 1998, there were 12,297,541 shares of Common Stock
outstanding held of record by approximately 108 stockholders. As of March 31,
1998, options to purchase an aggregate of 2,261,708 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, 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.
 
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.
 
 
                                      55
<PAGE>
 
  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 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.
 
CERTAIN PROVISIONS OF DELAWARE LAW
 
  The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), a provision that, in general, 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
 
                                      56
<PAGE>
 
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 2,935,736 shares of Common Stock 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 the
Company's initial public 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
than 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 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
the Company's initial public offering or more than the earlier of five years
after the closing of the Company's initial public 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 BankBoston, N.A. Its address is
150 Royall Street, Canton, Massachusetts 02021, and its telephone number is
(617) 575-3120.

                        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 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 13,266,411 shares of Common Stock (based upon shares outstanding
at March 31, 1998), assuming no exercise of the Underwriters' over-allotment
option and no exercise of outstanding options. Of these shares, the 3,300,000
shares sold in this Offering and the 3,335,000 shares sold in the Company's
initial public 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 6,631,411 shares of Common Stock held by officers,
directors, employees, consultants and other stockholders of the Company are
"restricted shares" as that term is defined in Rule 144 (the "Restricted
Shares") and were sold by the Company in reliance upon exemptions from the
registration requirements of the Securities Act. 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 621,429 shares will become eligible for sale upon
expiration of lock-up agreements on August 1, 1998 (iii) approximately
2,457,321 shares will become eligible for sale 90 days after the date of this
Prospectus and (iv) approximately 3,552,661 shares will become eligible 180
days after the date of this Prospectus.
 
  In addition to the restrictions under the Securities Act set forth above,
the number of shares of Common Stock available for sale in the public market
is limited by (i) lock-up agreements executed by optionholders and
substantially all stockholders of the Company in connection with the Company's
initial public offering in February 1998, which agreements expire on August 1,
1998, (ii) lock-up agreements entered into by Selling Stockholders who are
current officers or founders in connection with this Offering under which such
Selling Stockholders have agreed not to sell or otherwise dispose of any of
their shares for a period of 180 days from the date of this Prospectus and
(iii) lock-up agreements entered into by officers (who are not Selling
Stockholders), directors and Selling Stockholders (other than current founders
and officers) in connection with this Offering under which such persons have
agreed not to sell or otherwise dispose of any of their shares for a period of
90 days from the date of this Prospectus. 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 such 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 on or about May
3, 1998, 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 132,664 shares immediately after
this Offering); or (ii) the average weekly trading volume of the Common Stock
on the Nasdaq National Market during the four
 
                                      58
<PAGE>
 
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 limitation or notice provisions of Rule 144; therefore,
unless otherwise restricted, "144(k) shares" become saleable upon the
completion of the Company's initial public 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 the
Company's initial public 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 2,935,736 shares of Common
Stock, or their transferees, will be entitled to certain rights with respect
to the registration of such shares under the Securities Act. See "Description
of Capital Stock--Registration Rights." Registration of such shares under the
Securities Act would result in such shares becoming freely 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
and Director Plan. See "Management--Stock Plans." Such registration statement
is expected to be filed and become effective on or prior to July 31, 1998.
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 March 31, 1998, options to purchase 2,261,708
shares of Common Stock were outstanding, of which options to purchase
approximately 263,646 shares were then vested and exercisable. At March 31,
1998, no shares had been issued under the Purchase Plan. Beginning upon the
expiration of the lock-up agreements described above, approximately 432,695
shares issuable upon the exercise of vested stock options will become eligible
for sale in the public market, if such options are exercised.

  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 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 has granted to the
Underwriters an option to purchase up to 495,000 additional shares of Common
Stock, to cover over-allotments, if any, at the 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 Company 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

of the Synopsys Shares by selling short through Deutsche Morgan Grenfell Inc.
an equivalent number of shares of Common Stock as part of this Offering.
Synopsys has agreed to lend to Deutsche Bank all of the Synopsys Shares prior
to the closing date of this Offering so that Deutsche Bank can use the

shares, Deutsche Bank will provide to Synopsys cash collateral equal to 102%
of the market value of the borrowed shares and will receive interest thereon
from Synopsys. Deutsche Bank's short sale, and the accompanying borrowing
arrangement with Synopsys, are being effected pursuant to the Registration
Statement, and Deutsche Morgan Grenfell Inc. will deliver this Prospectus in
connection with any sales effected on Deutsche Bank's behalf. Deutsche Morgan
Grenfell Inc. will act as agent to Deutsche Bank and Synopsys in connection
with the forward sale and borrowing arrangements. In connection with such
arrangements, Synopsys 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. Deutsche Morgan Grenfell Inc. has also provided investment banking
services to Synopsys in the past, and Synopsys is one of the Company's primary
competitors. See "Risk Factors--Competition."
 
  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
 
                                      61
<PAGE>
 
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.
 
  The Underwriters and dealers may engage in passive market making
transactions in the Common Stock in accordance with Rule 103 of Regulation M
promulgated by the Commission. In general, a passive market maker may not bid
for, or purchase, the Common Stock at a price that exceeds the highest
independent bid. In addition, the net daily purchases made by any passive
market maker generally may not exceed 30% of its average daily trading volume
in the Common Stock during a specified two month prior period, or 200 shares,
whichever is greater. A passive market maker must identify passive market
making bids as such on the Nasdaq electronic interdealer reporting system.
Passive market making may stabilize or maintain the market price of the Common
Stock above independent market levels. Underwriters and dealers are not
required to engage in passive market making and may end passive market making
activities at any time.

                       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 ICs 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 received under the terms of license
agreements with customers to provide the Company's IP component products which
are customized to each customer's manufacturing process. IP component products
consist of data and/or software and related documentation which enables a
customer to design and manufacture complex integrated circuits. The software,
if any, included in the Company's IP component products is incidental. The
purpose of the license is to permit the customer to use the Company's IP in
connection with the design and manufacture of the customers' products. The
customization of the IP component products generally takes up to six months to
complete and the customer obtains ownership rights to the in-process
customization as well as the completed customization. The license period is
typically twenty years. Under the terms of a typical license agreement, a
portion of the fees are paid on signing of the agreement with the final
payment due within 30 days of completion of customization. The Company
warrants that the licensed products shall be free from defects and conform to
customer's specifications. The warranty period is typically 90 days but can
extend to a maximum of one year. Some licenses provide for ongoing product
support, which is insignificant, that consists of an identified customer
contact at the Company and telephonic or e-mail product support. No upgrades
or modifications to the licensed product are provided. The product support
period is generally three years. Other than warranty and ongoing product
support, the Company has no further obligations subsequent to completion of
the customization. Revenue from license fees is recognized based on the
percentage of completion method over the period that the Company completes
customization for the majority of the Company's contracts. Under certain
contracts where the costs cannot be estimated, the completed contract method
is utilized whereby revenue and costs are recognized when the Company
completes customization. Under the percentage of completion and completed
contract methods, provisions for estimated losses on uncompleted contracts are
recognized in the period in which the likelihood of such losses is determined.
 
  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 and
product support costs and is recognized on the percentage of completion
method.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
 
 Product Development
 
  Product development expenses are charged to operations as incurred.
 
 Earnings Per Share (EPS)--See Note 14
 
 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 using 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.
 
 Unaudited Interim Financial Information
 
  The accompanying interim balance sheet as of March 31, 1998 and the
statements of operations and cash flows for the six months ended March 31,
1997 and 1998 together with the related notes are unaudited but include all
adjustments, consisting of only normal recurring adjustments, which the
Company considers necessary to present fairly, in all material respects, the
financial position, the results of operations and cash flows for the six
months ended March 31, 1997 and 1998. Results for the six months ended March
31, 1997 and 1998 are not necessarily indicative of results for an entire
year.
 
Recent Pronouncements
 
  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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
 
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.
 
  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 that 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. At March 31, 1998,
five customers accounted for 20%, 19%, 14%, 14% and 12%, respectively, of
contract receivables.
 
  As of March 31, 1998, 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 one
year.
 
4. CONTRACT RECEIVABLES:
 
  Contract receivables were comprised of the following (in thousands):

follows:
 
 Dividends
 
  The holders of Series A and Series B Preferred Stock are entitled to
dividends in preference to Common Stockholders of $0.15461 and $0.377 per
annum, respectively. Any dividends would be noncumulative and no right to such
dividends would accrue to holders of Preferred Stock unless declared by the
Board of Directors. As of September 30, 1997, no dividends have been declared.
 
 Conversion, Participation and Registration
 
  The Series A and Series B Preferred Stock is convertible, at the option of
the holders, at any time, into Common Stock at conversion values of $1.5461
and $3.77, respectively, subject to certain antidilution adjustments.
Conversion is automatic upon the closing of a firm commitment underwritten
public offering having an aggregate offering price of at least $10,000,000.
The Preferred Stockholders have certain registration rights and the right to
participate in future issuances of the Company's stock. Additionally, the
Preferred Stockholders have the right of first refusal and the right to
participate, should the major Common Stockholder sell shares, which rights
also terminate upon the closing of a firm commitment underwritten public
offering. The Company has reserved 3,385,736 shares of Common Stock in the
event of conversion.
 
 Voting
 
  Each share of Series A and Series B Preferred Stock has voting rights equal
to the number of Common Stock into which it converts. In addition, the holders
of Series A Preferred Stock have the right to elect two members of the Board
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
holders of both classes of stock.
 
 Liquidation
 
  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

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

issued a warrant to purchase an aggregate of 50,000 shares of Series B
Preferred Stock at an exercise price of $3.77 and an additional, variable
amount of Series B Preferred Stock, at a price to be determined at the time of

connection with such warrant or otherwise, will increase Synopsys' aggregate
percentage ownership to 9.9% of the Company's issued and outstanding capital
stock at the time of such exercise. The exercise price for the Additional
Shares would vary depending on the event that triggered the exercisability of
the warrant and on an issuance of Additional Shares in conjunction with an
initial public offering, the exercise price will be the public offering price
per share less any underwriting discounts and commissions. The Company has
reserved 50,000 shares of Common Stock for issuance upon exercise of the
warrant.
 
 Stock Option Plan
 
  The Company had reserved 4,491,396 shares of its Common Stock under its 1993

Plan for issuance upon the exercise of nonstatutory and incentive stock
options to employees and consultants as of September 30, 1997. In November

the reservation of an additional two million shares for issuance under the
1993 Plan. The 1993 Plan expires in 2003 and the 1997 Director Option Plan

at a price not less than 85% of fair market value in the case of nonstatutory
stock options, and at fair market value in the case of incentive stock
options. Fair market value is determined by the Board of Directors. Options

after the date of grant.

9. STOCKHOLDERS' EQUITY, CONTINUED:
 
  At September 30, 1995, 1996 and 1997, and March 31, 1998, options to
purchase 225,917, 303,235, 291,011 and 263,646 shares of Common Stock,
respectively, were exercisable.
 
  In connection with the grant of options for the purchase of 96,200 shares of
Common Stock to employees during the period from December 1996 through March
1997, the Company recorded aggregate deferred compensation of approximately
$198,000 representing the difference between the deemed fair value of the
Common Stock and the option exercise price at date of grant. Such deferred
compensation will be amortized over the vesting period relating to these
options, of which $41,000 and $24,000 has been amortized during the year ended
September 30, 1997 and the six month period ended March 31, 1998,
respectively.
 
 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. Had compensation expense been determined at the
fair value on the grant dates for awards under the Plan consistent with the
method of SFAS No. 123, the Company's net income in 1996 and 1997 would have
been reduced to the pro forma amounts indicated below (in thousands):

Such difference may not be representative of future compensation cost because
options vest over several years and additional grants are made each year.
 
  The fair value of each option grant is estimated on the date of grant using
the minimum value method with the following weighted assumptions:

  The expected average life is based upon the assumption that the stock

weighted average remaining contract life was 9.3 and 8.9 years, as of
September 30, 1996 and 1997, respectively.

  Prior to March 1996, the Company was organized as a subchapter S corporation
and profits and losses for these periods flowed through to the shareholders.
Deferred tax assets and liabilities associated with temporary differences at
the termination of S corporation status were recorded with a corresponding
charge to provision for income taxes. Taxes reflected in the 1995 financial
statements represent foreign income and franchise taxes imposed on S
corporations by California.

12. BENEFIT PLAN:
 
  The Company sponsors a 401(k) profit sharing plan (the "401(k) Plan") for
substantially all employees. The 401(k) Plan provides for profit sharing
contributions to be made at the discretion of the Company's Board of
Directors. The Company did not elect to make a profit sharing contribution for
fiscal 1995, 1996 or 1997.
 
  The 401(k) Plan also provides for elective employee salary reduction
contributions and Company matching of employees' contributions. Employees may

14. EARNINGS PER SHARE (EPS) DISCLOSURES:
 
  The Company has adopted the provisions of Statement of Financial Accounting
Standards No. 128, Earnings Per Share ("SFAS 128") effective December 31,
1997. SFAS 128 requires the presentation of basic and diluted earnings per
share. Basic EPS is computed by dividing income available to common
stockholders by the weighted average number of common shares outstanding for
the period. Diluted EPS is computed giving effect to all dilutive potential
common shares that were outstanding during the period. Dilutive potential
common shares consist of the incremental common shares issuable upon the
conversion of convertible preferred stock (using the "if converted" method)
and exercise of stock options and warrants for all periods. All prior period
earnings per share amounts have been restated to comply with the SFAS 128.
 
  In accordance with the disclosure requirements of SFAS 128, a reconciliation
of the numerator and denominator of basic and diluted EPS is provided as
follows (in thousands, except per share amounts).

15. SUBSEQUENT EVENTS:
 
  In November 1997, the Board of Directors and the stockholders approved the
reincorporation of the Company in Delaware. Under the new Certificate of
Incorporation in Delaware, the Company is authorized to issue 50,000,000
shares of Common Stock at $0.001 par value and 5,000,000 shares of Preferred
Stock at $0.001 par value. The reincorporation occurred on January 9, 1998.
 
  In November 1997, the Board of Directors and the stockholders authorized
management of the Company to file a Registration Statement with the Securities
and Exchange Commission relating to a public offering of the Company's Common
Stock.
 
  In November 1997, the Board of Directors and the stockholders also approved

issuance under the 1993 Plan.
 
  The 1997 Employee Stock Purchase Plan authorizes the granting of stock
purchase rights to eligible employees during two-year offering periods with
exercise dates approximately every six months. The Board of Directors reserved
600,000 shares of common stock for issuance under the plan. Shares are
purchased through employees' payroll deductions at purchase prices equal to
85% of the lesser of the fair market value of the Company's Common Stock at
either the first day of each offering period or the date of purchase.
 
  A total of 200,000 shares of Common Stock have been reserved for issuance
under the 1997 Director Option Plan.
 
  On February 6, 1998, the Company completed the public offering of 3,015,000
shares of Common Stock through a Registration Statement declared effective by
the Securities and Exchange Commission on February 2, 1998. In connection with
such public offering, certain stockholders of the Company sold 320,000 shares
of the Company's Common Stock.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Registrant is 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
 
                                     II-1
<PAGE>
 
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 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.
 
  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 and 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 December 31, 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 March 1997 and
the one-for-two reverse stock split effected in November 1997):
 
1. From December 31, 1994 to March 31, 1998, the Registrant issued and sold
   817,192 shares of Common Stock to employees and consultants at prices
   ranging from $0.01 to $2.00 per share, upon exercise of stock options,
   pursuant to the Registrant's 1993 Stock Option Plan.
 
2. On September 30, 1997, the Registrant issued 20,602 shares of Common Stock
   to employees as a stock bonus.
 
3. On March 21, 1996, the Registrant issued and sold 2,263,802 shares of
   Series A Preferred Stock to a total of four investors for an aggregate
   purchase price of $3,500,059.64.
 
                                     II-2
<PAGE>
 
4. On December 17, 1996, the Registrant issued and sold 1,121,934 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. Such warrant was exercised prior to the
   closing of the Registrant's initial public offering on February 6, 1998 for
   50,000 shares at $3.77 per share. The warrant terminated with respect to
   any additional shares upon the closing of the Registrant's initial public
   offering.
 
  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 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.

Section 2.  Purchase and Closing.
            -------------------- 

          (a) On the basis of the representations, warranties, agreements and
covenants herein contained and subject to the terms and conditions herein set
forth, the Company agrees to issue and sell, and the Selling Stockholders
propose to sell, to each of the Underwriters, and each of the Underwriters,
severally and not jointly, agrees to purchase from the Company and the Selling
Stockholders, at a purchase price of $____ per Share (the "Purchase Price"), the
respective number

                                       2
<PAGE>
 
of Firm Shares set forth opposite the name of such Underwriter in Schedule 1
hereto. Firm Shares shall be registered by BankBoston, N.A. in the name of the
nominee of the Depository Trust Company ("DTC"), Cede & Co. ("Cede & Co."), and
credited to the accounts of such of its participants as the Representatives
shall request, upon notice to the Company and the Selling Stockholders at least
48 hours prior to the First Closing Date (as defined below), with any transfer
taxes payable in connection with the transfer of the Firm Shares to the
Underwriters duly paid, against payment by or on behalf of the Underwriters to
the account of the Company and the Selling Stockholders of the aggregate
Purchase Price therefor by wire transfer in immediately available funds.
Delivery or registry of and payment for the Firm Shares shall be made at the
offices of Wilson Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo
Alto, California 94304 at 9:30 A.M., New York City time, on the fourth full
business day following the date of this Agreement, or at such other place, time
or date as the Representatives, the Company and the Selling Stockholders may
agree upon. Such time and date of delivery against payment are herein referred
to as the "First Closing Date", and the implementation of all the actions
described in this Section 2(a) is herein referred to as the "First Closing".

          (b) For the purpose of covering any over-allotments in connection
with the distribution and sale of the Firm Shares as contemplated by the
Prospectus, the Company hereby grants to the several Underwriters an option to
purchase, severally and not jointly, the Option Shares. The purchase price to
be paid for any Option Shares shall be the same as the Purchase Price for the
Firm Shares set forth above in paragraph (a) of this Section 2. The option
granted hereby may be exercised as to all or any part of the Option Shares
from time to time within thirty days after the date of the Prospectus (or, if
such 30th day shall be a Saturday or Sunday or a holiday, on the next business
day thereafter when the New York Stock Exchange and the Nasdaq Stock Market's
National Market (the "Nasdaq National Market") are open for trading). The
Underwriters shall not be under any obligation to purchase any of the Option
Shares prior to the exercise of such option. The Representatives may from time
to time exercise the option granted hereby by giving notice in writing or by
telephone (confirmed in writing) to the Company setting forth the aggregate
number of Option Shares as to which the several Underwriters are then
exercising the option and the date and time for delivery or registry of and
payment for such Option Shares. Any such date of delivery or registry shall be
determined by the Representatives but shall not be earlier than two business
days or later than five business days after such exercise of the option and,
in any event, shall not be earlier than the First Closing Date. The time and
date set forth in such notice, or such other time or date as the
Representatives and the Company may agree upon or as the Representatives may
determine pursuant to Section 2(a) hereof, is herein called an "Option Closing
Date" with respect to such Option Shares, and the implementation of all the
actions described in this Section 2(b) is herein referred to as the "Option
Closing". As used in this Agreement, the term "Closing Date" means either the
First Closing Date or any Option Closing Date, as applicable, and the term
"Closing" means either the First Closing or any Option Closing, as applicable.
If the option is exercised as to all or any portion of the Option Shares, then
either one or more certificates in definitive form for such Option Shares
shall be delivered or, if such Option Shares are to be held through DTC, such
Option Shares shall be registered and credited, on the related Option Closing
Date in the same manner, and upon the same terms and conditions, set forth in
paragraph (a) of this Section 2, except that reference therein to the Firm
Shares and the First Closing Date shall be deemed, for purposes of this
paragraph (b), to refer to such Option Shares and Option Closing Date,
respectively. Upon

                                       3
<PAGE>
 
exercise of the option as provided herein, the Company shall become obligated
to sell to each of the several Underwriters, and, on the basis of the
representations, warranties, agreements and covenants herein contained and
subject to the terms and conditions herein set forth, each of the Underwriters
(severally and not jointly) shall become obligated to purchase from the
Company, the same percentage of the total number of the Option Shares as to
which the several Underwriters are then exercising the option as such
Underwriter is obligated to purchase of the aggregate number of Firm Shares,
as adjusted by the Representatives in such manner as they deem advisable to
avoid fractional shares.

          (c) The Company and the Selling Stockholders hereby acknowledge that
the payment of monies pursuant to Section 2(a) hereof (a "Payment") by or on
behalf of the Underwriters of the aggregate Purchase Price for any Shares does
not constitute closing of a purchase and sale of the Shares.  Only execution and
delivery, by facsimile or otherwise, of a receipt for Shares by the Underwriters
indicates completion of the closing of a purchase of the Shares from the Company
and the Selling Stockholders.  Furthermore, in the event that the Underwriters
make a Payment to the Company and the Selling Stockholders prior to the
completion of the closing of a purchase of Shares, the Company and the Selling
Stockholders hereby acknowledge that until the Underwriters execute and deliver
such receipt for the Shares, the Company and the Selling Stockholders will not
be entitled to the Payment and shall return the Payment to the Underwriters as
soon as practicable (by wire transfer of same-day funds) upon demand.  In the
event that the closing of a purchase of Shares is not completed and the Payment
is not returned by the Company and the Selling Stockholders to the Underwriters
on the same day the Payment was received by the Company and the Selling
Stockholders, the Company and the Selling Stockholders agree to pay to the
Underwriters in respect of each day the Payment is not returned by them, in
same-day funds, interest on the amount of such Payment in an amount representing
the Underwriters' cost of financing as reasonably determined by the
Representatives, pro rata in proportion to the percentage of such Payment
                 --------                                                
received by each.

          (d) It is understood that any of you, individually and not as one of
the Representatives, may (but shall not be obligated to) make Payment on behalf
of any Underwriter or Underwriters for any of the Shares to be purchased by such
Underwriter or Underwriters.  No such Payment shall relieve such Underwriter or
Underwriters from any of its or their obligations hereunder.

Section 3.  Covenants.
            --------- 

          (a) The Company covenants and agrees with the several Underwriters
that:
                 
               (i)  The Company will:

                    Agreement, and any amendments thereto to become effective as
                    promptly as possible.  If

                                       4

                    within the time period required by Rules 434 and 424(b)
                    under the Securities Act. During any time when a prospectus
                    relating to the Shares is required to be delivered under the
                    Securities Act, the Company (I) will comply with all
                    requirements imposed upon it by the Securities Act and the
                    rules and regulations of the Commission thereunder to the
                    extent necessary to permit the continuance of sales of or
                    dealings in the Shares in accordance with the provisions
                    hereof and of the Prospectus, as then amended or
                    supplemented, and (II) will not file with the Commission the
                    Prospectus, Term Sheet, any amendment or supplement to such
                    Prospectus or Term Sheet, any amendment to the Registration
                    Statement (including the amendment referred to in the second
                    sentence of Section 5(a)(i) hereof) or any Rule 462(b)
                    Registration Statement unless the Representatives previously
                    have been advised of, and furnished with a copy within a
                    reasonable period of time prior to, the proposed filing and
                    the Representatives shall have given their consent to such
                    filing. The Company will prepare and file with the
                    Commission, in accordance with the rules and regulations of
                    the Commission, promptly upon request by the Representatives
                    or counsel for the Underwriters, any amendments to the
                    Registration Statement or amendments or supplements to the
                    Prospectus that may be necessary or advisable in connection
                    with the distribution of the Shares by the several
                    Underwriters. The Company will advise the Representatives,
                    promptly after receiving notice thereof, of the time when
                    the Registration Statement or any amendment thereto has been
                    filed or declared effective or the Prospectus or Term Sheet
                    or any amendment or supplement thereto has been filed and
                    will provide evidence satisfactory to the Representatives of
                    each such filing or effectiveness.

                    (y) without charge, provide (I) to each of the
                    Representatives and to counsel for the Underwriters, an
                    executed and a conformed copy of the Original Registration
                    Statement and each amendment thereto or any Rule 462(b)
                    Registration Statement (in each case including exhibits
                    thereto), (II) to each other Underwriter, a conformed copy
                    of the Original Registration Statement and each amendment

                    case without exhibits thereto), and (III) so long as a
                    prospectus relating to the Shares is required to be

                    Preliminary Prospectus or the Prospectus or any amendment or

                    or (B) 6:00 P.M., New York City time, on the second business
                    day following the date of determination of the public
                    offering price, if such determination occurred after 12:00
                    noon, New York City time, on such date, will deliver to the
                    Underwriters, without charge, as many copies of the
                    Prospectus and any amendment or supplement thereto as the
                    Representatives may reasonably request for purposes of
                    confirming orders that are expected to settle on the First
                    Closing Date.

                    (z) advise the Representatives, promptly after receiving
                    notice or obtaining knowledge thereof, of (I) the issuance
                    by the Commission of any stop order suspending the
                    effectiveness of the Original Registration Statement or any
                    amendment thereto or any Rule 462(b) Registration Statement
                    or any order preventing or suspending the use of any

                    proceeding for any purpose identified in the preceding
                    clause (I) or (II), or (IV) any request made by the
                    Commission for amending the Original Registration Statement

                    supplementing the Prospectus or for additional information.
                    The Company will use all reasonable efforts to prevent the
                    issuance of any such stop order and, if any such stop order
                    is issued, to obtain the withdrawal thereof as promptly as

               pursuant to applicable state securities ("Blue Sky") laws of
               certain states of the United States of America or other U.S.
               jurisdictions, and the Company shall maintain such qualifications
               in effect for so long as may be necessary in order to complete
               the placement of the Shares; provided, however, that the Company
               shall not be obliged to file any general consent to service of
               process or to qualify as a foreign corporation or as a securities
               dealer in any jurisdiction or to subject itself to taxation in
               respect of doing business in any jurisdiction in which it is not
               otherwise so subject.

               (iii)  If, at any time prior to the final date when a prospectus
               relating to the Shares is required to be delivered under the
               Securities Act, any event occurs as a result of which the
               Prospectus, as then amended or supplemented, would include any
               untrue statement of a material fact or omit to state any material
               fact necessary in order to make the statements therein, in the
               light of the circumstances under which they were made, not
               misleading, or if for any other reason it shall be necessary at
               any time to amend the Registration

               person acting on behalf of any of them will, directly or
               indirectly, (x) take any action designed to cause or to result

               sole judgment the market price of the Shares has been or is
               likely to be materially affected (regardless of whether such
               rumor, publication or event necessitates a supplement to or
               amendment of the Prospectus), the Company will, after notice from
               the Representatives advising the Company to the effect set forth
               above, forthwith prepare, consult with the Representatives
               concerning the substance of, and disseminate a press release or
               other public statement reasonably satisfactory to the
               Representatives, responding to or commenting on such rumor,
               publication or event.

               (x) If the Company elects to rely on Rule 462(b), the Company
               shall both file the Rule 462(b) Registration Statement with the
               Commission in compliance with Rule 462(b) and pay the applicable
               fees in accordance with Rule 111 promulgated under the Securities
               Act by the earlier of (x) 10:00 P.M. New York City time on the
               date of this Agreement and (y) the time confirmations are sent or
               given, as specified by Rule 462(b)(2) under the Securities Act.

               (xi) The Company will cause the Shares to be duly included for
               quotation on the Nasdaq National Market prior to the First
               Closing Date.  The Company will use all reasonable efforts to
               ensure that the Shares remain included for quotation on the
               Nasdaq National Market following the First Closing Date.

          (b) Each Selling Stockholder agrees that:

               (i) It will not, and no person acting on behalf of such Selling
               Stockholder will, directly or indirectly, (x) take any action
               designed to cause or to result in, or that has constituted or
               which might reasonably be expected to constitute, the
               stabilization or manipulation of the price of any security of the
               Company to facilitate the sale or resale of the Shares or (y) (I)
               sell, bid for, purchase, or pay anyone any compensation for
               soliciting purchases of, the Shares or (II) pay or agree to pay
               to any person any compensation for soliciting another to purchase
               any other securities of the Company (except for the sale of
               Shares by the Selling Stockholders under this Agreement).

               (ii) It will not, and will not allow any subsidiary to, publicly
               announce any intention to, and will not itself, and will not
               allow any subsidiary to, without the prior written consent of the
               Representatives on behalf of the Underwriters, (x) offer, pledge,
               sell, offer to sell, contract to sell, sell any option or
               contract to purchase, purchase any option to sell, grant any

               other agreement that transfers, in whole or in part, any of the
               economic consequences of ownership of the shares of Common Stock
               or any securities convertible into, or exercisable or

               transaction described in clause (x) or (y) above is to be settled
               by delivery of shares of Common Stock or such other securities,
               in cash or otherwise), in each case, beneficially owned (within
               the meaning of Rule 13d-3 under the Exchange Act) or otherwise
               controlled by such person on the date hereof or hereafter
               acquired, for a period beginning from the date hereof and

               however, that such Selling Stockholder may, without the prior
               written consent of the Representatives on behalf of the
               Underwriters, transfer shares of Common Stock or such other
               securities to members of such Selling Stockholder's immediate
               family or to trusts for the benefit of members of such Selling
               Stockholder's immediate family or in connection with bona fide
               gifts, provided that any transferee agrees to the transfer

Section 5.  Representations and Warranties.
            ------------------------------ 

          (a) As a condition of the obligation of the Underwriters to underwrite
and purchase the Shares, the Company and, to the best of their knowledge after
careful review of this Agreement, the Registration Statement and the Prospectus,
the Principal Selling Stockholders, Daniel I. Rubin and the Selling Stockholders
affiliated with U.S. Venture Partners represent and warrant to, and agree with,
each of the several Underwriters as follows:

          Registration Statement and Prospectus

               (i) The Original Registration Statement, including the
          Preliminary Prospectus, has been filed by the Company with the
          Commission under the Securities Act, and one or more amendments to
          such Registration Statement may have been so filed.  After the
          execution of this Agreement, the Company will file with the Commission
          either (x) if such Registration Statement, as it may have been
          amended, has been declared by the Commission to be effective under the
          Securities Act, either (I) if the Company relies on Rule 434 under the
          Securities Act, a Term Sheet relating to the Shares that shall
          identify the Preliminary Prospectus that it supplements containing
          such information as is required or permitted by Rules 434, 430A and
          424(b) under the Securities Act or (II) if the Company does not rely
          on Rule 434 under the Securities Act, a prospectus in the form most
          recently included in an amendment to such Registration Statement (or,
          if no such amendment shall have been filed, in such Registration
          Statement), with such changes or insertions as are required by Rule
          430A under the Securities Act or permitted by Rule 424(b) under the
          Securities Act, and in the case of either clause (I) or (II) of this
          sentence, as have

                                       10
<PAGE>
 
          been provided to and approved by the Representatives prior to the
          execution of this Agreement, or (y) if such Registration Statement, as
          it may have been amended, has not been declared by the Commission to
          be effective under the Securities Act, an amendment to such
          Registration Statement, including a form of prospectus, a copy of
          which amendment has been furnished to and approved by the
          Representatives prior to the execution of this Agreement. The Company
          may also file a Rule 462(b) Registration Statement with the Commission
          for the purpose of registering certain additional Shares, which
          registration shall be effective upon filing with the Commission.

               (ii) The Commission has not issued any order preventing or
          suspending the use of any Preliminary Prospectus.  When any
          Preliminary Prospectus was filed with the Commission, it (x) contained
          all statements required to be stated therein in accordance with, and
          complied in all material respects with the requirements of, the
          Securities Act and the rules and regulations of the Commission
          thereunder and (y) did not include any untrue statement of a material
          fact or omit to state any material fact necessary in order to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading.  When the Registration Statement or any
          amendment thereto was or is declared effective, it (I) contained or
          will contain all statements required to be stated therein in
          accordance with, and complied or will comply in all material respects
          with the requirements of, the Securities Act and the rules and
          regulations of the Commission thereunder and (II) did not or will not
          contain any untrue statement of a material fact or omit to state any
          material fact required to be stated therein or necessary to make the
          statements therein not misleading.  When the Prospectus or any Term
          Sheet that is a part thereof or any amendment or supplement to the
          Prospectus is filed with the Commission pursuant to Rule 424(b) (or,
          if the Prospectus or such amendment or supplement is not required to
          be so filed, when the Registration Statement or the amendment thereto
          containing the Prospectus or such amendment or supplement to the
          Prospectus was or is declared effective) and on the Closing Date, the
          Prospectus, as amended or supplemented at any such time, (A) contained
          or will contain all statements required to be stated therein in
          accordance with, and complied or will comply in all material respects
          with the requirements of, the Securities Act and the rules and
          regulations of the Commission thereunder and (B) did not or will not
          include any untrue statement of a material fact or omit to state any
          material fact necessary in order to make the statements therein, in
          the light of the circumstances under which they were made, not
          misleading.  The foregoing provisions of this paragraph (ii) do not
          apply to statements or omissions made in any Preliminary Prospectus,
          the Registration Statement or any amendment thereto or the Prospectus
          or any amendment or supplement thereto in reliance upon and in
          conformity with written information furnished to the Company by any
          Underwriter through the Representatives specifically for use therein.

               (iii)  If the Company has elected to rely on Rule 462(b) and the
          Rule 462(b) Registration Statement is not effective, (x) the Company
          will file a Rule 462(b) Registration Statement in compliance with, and
          that is effective upon filing

                                       11
<PAGE>
 
          pursuant to, Rule 462(b) and (y) the Company has given irrevocable
          instructions for transmission of the applicable filing fee in
          connection with the filing of the Rule 462(b) Registration Statement,
          in compliance with Rule 111 under the Securities Act, or the
          Commission has received payment of such filing fee.

               (iv) If the Company has elected to rely on Rule 434 under the
          Securities Act, the Prospectus is not "materially different", as such
          term is used in Rule 434, from the prospectus included in the
          Registration Statement at the time of its effectiveness or an
          effective post-effective amendment thereto (including such information
          that is permitted to be omitted pursuant to Rule 430A under the
          Securities Act).

               (v) The Company has not distributed and, prior to the later of
          (x) any Closing Date and (y) the completion of the distribution of the
          Shares, will not distribute any offering material in connection with
          the Offering other than the Registration Statement or any amendment
          thereto, any Preliminary Prospectus or the Prospectus or any amendment
          or supplement thereto.

               (vi) Subsequent to the respective dates as of which information
          is given in the Registration Statement and the Prospectus, (x) the
          Company and its subsidiary, taken as a whole, have not incurred any
          material liability or obligation, direct or contingent, nor entered
          into any material transaction not in the ordinary course of business;
          (y) the Company has not purchased any of its outstanding capital
          stock, nor declared, paid or otherwise made any dividend or
          distribution of any kind on its capital stock; and (z) there has not
          been any material change in the capital stock, short-term or long-term
          debt of the Company and its subsidiary, taken as a whole, except in
          each case as described in or contemplated by the Prospectus.

          The Shares

               (vii)  The Company has an authorized, issued and outstanding
          capitalization as set forth in the Prospectus.  All of the issued
          shares of capital stock of the Company have been duly authorized and
          validly issued and are fully paid and nonassessable, have been issued
          in compliance with all applicable federal and state securities laws
          and were not issued in violation of or subject to any preemptive
          rights or other rights to subscribe for or purchase such securities.
          The Shares have been duly authorized by all necessary corporate action
          of the Company and, after payment therefor in accordance herewith,
          will be validly issued, fully paid and nonassessable at the Closing
          Date.  No holders of outstanding shares of capital stock of the
          Company are entitled as such to any preemptive or other rights to
          subscribe for any of the Shares, and no holder of securities of the
          Company has any right which has not been fully exercised or waived to
          require the Company to register the offer or sale of any securities
          owned by such holder under the Securities Act in the Offering
          contemplated by this Agreement.

               (viii)  Except as disclosed in the Prospectus, there are no
          outstanding (x) securities or obligations of the Company or its
          subsidiary convertible into or

                                       12
<PAGE>
 
          exchangeable for any capital stock of the Company or its subsidiary,
          (y) warrants, rights or options to subscribe for or purchase from the
          Company or its subsidiary any such capital stock or any such
          convertible or exchangeable securities or obligations, or (z)
          obligations of the Company or its subsidiary to issue any shares of
          capital stock, any such convertible or exchangeable securities or
          obligations, or any such warrants, rights or options.

               (ix) Except for the shares of its subsidiary owned by the
          Company, neither the Company nor its subsidiary owns any shares of
          stock or any other equity securities of any corporation or has any
          equity interest in any firm, partnership, association or other entity,
          except as described in or contemplated by the Registration Statement.

          Listing

               (x) All of the Shares have been duly authorized and accepted for
          quotation on the Nasdaq National Market, subject to official notice of
          issuance.

          Market manipulation

          person acting on behalf of any of them has, directly or indirectly,
          (x) taken any action designed to cause or to result in, or that has
          constituted or which might reasonably be expected to constitute, the
          stabilization or manipulation of the price of any security of the
          Company to facilitate the sale or resale of the Shares, or (y) since
          the filing of the Original Registration Statement (I) sold, bid for,
          purchased, or paid anyone any compensation for soliciting purchases
          of, the Shares or (II) paid or agreed to pay to any person any
          compensation for soliciting another to purchase any other securities
          of the Company.

          Corporate power and authority

               (xii)  The Company has been duly incorporated and is validly

          and is in good standing in each jurisdiction in which its ownership,
          leasing or operation of its properties or assets or the conduct of its
          business requires such qualification, except where the failure to be
          so qualified does not amount to a material liability or disability to
          the Company and its subsidiary, taken as a whole, and has full power
          and authority to execute and perform its obligations under this
          Agreement; the subsidiary of the Company is a corporation duly
          incorporated and validly existing as a corporation in good standing
          under the laws of its jurisdiction of incorporation and is duly
          qualified to transact business and is in good standing in each
          jurisdiction in which the ownership, leasing or operation of its
          properties or assets or the conduct of its business requires such
          qualification, except where the failure to be so qualified does not
          amount to a material liability or disability to the

                                       13
<PAGE>
 
          Company and its subsidiary, taken as a whole, and the subsidiary has
          full power and authority to own, lease and operate its properties and
          assets and conduct its business as described in the Registration
          Statement and the Prospectus; all of the issued and outstanding shares
          of capital stock of the subsidiary have been duly authorized and are

               (xiii)  The execution and delivery of this Agreement and the
          issuance and sale of the Shares have been duly authorized by all
          necessary corporate action of the Company, and this Agreement has been
          duly executed and delivered by the Company and is the valid and
          binding agreement of the Company, enforceable against the Company in
          accordance with its terms, except as its enforceability may be limited
          by bankruptcy, insolvency, reorganization, moratorium or other similar
          laws affecting the enforcement of creditors' rights generally.

               (xiv)  The issuance, offering and sale of the Shares to the
          Underwriters by the Company pursuant to this Agreement, the compliance
          by the Company with the other provisions of this Agreement and the
          consummation of the other transactions herein contemplated do not (x)
          require the consent, approval, authorization, registration or
          qualification of or with any governmental authority, except (I) if the
          Company has elected to rely on Rule 462(b) and the Rule 462(b)
          Registration Statement is not effective, the registration of certain
          Shares pursuant to the Rule 462(b) Registration Statement that will be
          effective upon filing in compliance with Rule 462(b) and (II) such as
          have been obtained or made or such as may be required by the state
          securities or Blue Sky laws of the various states of the United States
          of America or other U.S. jurisdictions or by the National Association
          of Securities Dealers, Inc. ("NASD") in connection with the offer and
          sale of the Shares by the Underwriters, or (y) conflict with or result
          in a breach or violation of any of the terms and provisions of, or
          constitute a default under, any material indenture, mortgage, deed of
          trust, lease or other agreement or instrument to which the Company or
          its subsidiary is a party or by which the Company or its subsidiary or
          any of their respective properties are bound, or the charter documents
          or by-laws of the Company or its subsidiary, or any statute or any
          judgment, decree, order, rule or regulation of any court or other
          governmental authority or any arbitrator applicable to the Company or
          its subsidiary.

               (xv) The Company is not, and will conduct its operations in a
          manner so that it continues not to be, an "investment company" and,

               (xxi)  The Company and its subsidiary maintain a system of
          internal accounting controls sufficient to provide reasonable
          assurance that (w) transactions are executed in accordance with
          management's general or specific authorizations; (x) transactions are
          recorded as necessary to permit preparation of financial statements in
          conformity with GAAP and to maintain asset accountability; (y) access
          to assets is permitted only in accordance with management's general or
          specific authorization; and (z) the recorded accountability for assets
          is compared with the existing assets at reasonable intervals and
          appropriate action is taken with respect to any differences.

          Litigation

               (xxii)  No legal or governmental proceedings are pending or
          threatened to which the Company or its subsidiary is a party or to
          which the property of the Company or its subsidiary is subject that
          are required to be described in the Registration Statement or the
          Prospectus and are not described therein; and no statutes,
          regulations, contracts or other documents that are required to be
          described in the Registration Statement or the Prospectus or to be
          filed as exhibits to the Registration Statement that are not described
          therein or filed as required.

          Dividends and Distributions

               (xxiii)  The subsidiary of the Company is not currently
          prohibited, directly or indirectly, from paying any dividends to the
          Company, making any other distribution on its capital stock, repaying
          to the Company any loans or advances to it from the Company or
          transferring any of its property or assets to the Company or any other
          subsidiary of the Company, and the Company is not currently
          prohibited, directly or indirectly, from paying any dividends or
          making any other distribution on its capital stock, in each case
          except as described in or contemplated by the Prospectus.

          Taxes

               (xxiv)  The Company has filed all foreign, federal, state and
          local tax returns that are required to be filed or has requested
          extensions of the time for filing thereof (except in any case in which
          the failure so to file would not have a materially

                                       16
<PAGE>
 
          adverse effect on the Company and its subsidiary, taken as a whole)
          and has paid all taxes required to be paid by it and any other
          assessment, fine or penalty levied against it, to the extent that any
          of the foregoing is due and payable, except for any such assessment,
          fine or penalty that is currently being contested in good faith or as
          described in or contemplated by the Prospectus.

          Insurance

               (xxv)  The Company and its subsidiary are insured by insurers of
          recognized financial responsibility against such losses and risks and
          in such amounts as are prudent and customary in their businesses as
          described in the Prospectus; neither the Company nor its subsidiary
          has been refused any insurance coverage sought or applied for; and
          neither the Company nor its subsidiary has any reason to believe that
          it will not be able to renew its existing insurance coverage as and
          when such coverage expires or to obtain similar coverage from similar
          insurers as may be necessary to continue its business at a cost that
          would not materially and adversely affect the condition (financial or
          otherwise), earnings, properties, business affairs or business
          prospects, net worth or results of operations of the Company and its
          subsidiary, taken as a whole, except as described in or contemplated
          by the Prospectus.

          Pension and Labor

               (xxvi)  The Company is in compliance in all material respects
          with all presently applicable provisions of the Employee Retirement
          Income Security Act of 1974, as amended, including the regulations and
          published interpretations thereunder ("ERISA"); no "reportable event"
          (as defined in ERISA) has occurred with respect to any "pension plan"
          (as defined in ERISA) for which the Company would have any liability;
          the Company has not incurred and does not expect to incur liability
          under (x) Title IV of ERISA with respect to termination of, or
          withdrawal from, any "pension plan" or (y) Sections 412 or 4971 of the
          Internal Revenue Code of 1986, as amended, including the regulations
          and published interpretations thereunder (the "Code"); and each
          "pension plan" for which the Company would have any liability that is
          intended to be qualified under Section 401(a) of the Code is so
          qualified in all material respects and nothing has occurred, whether
          by action or by failure to act, which would cause the loss of such
          qualification.

               (xxvii)  No labor dispute with the employees of the Company or
          its subsidiary exists or is threatened or imminent that could have a
          materially adverse effect on or constitute a materially adverse change
          in, or constitute a development involving a prospective materially
          adverse effect on or change in, the condition (financial or
          otherwise), properties, management, earnings, business affairs or
          business prospects, net worth or results of operations of the Company
          and its subsidiary, taken as a whole, except as described in or
          contemplated by the Prospectus.

          Environmental

               (xxviii)  Neither the Company nor its subsidiary is in violation
          of any federal or state law or regulation relating to occupational
          safety and health or to the storage, handling or transportation of
          hazardous or toxic materials and the Company and its subsidiary have
          received all permits, licenses or other approvals required of them
          under applicable federal and state occupational safety and health and
          environmental laws and regulations to conduct their respective
          businesses as described in the Prospectus, and the Company and its
          subsidiary are in compliance with all terms and conditions of any such
          permit, license or approval, except any such violation of law or
          regulation, failure to receive required permits, licenses or other
          approvals or failure to comply with the terms and conditions of such
          permits, licenses or approvals which would not, singly or in the
          aggregate, have a materially adverse effect on or constitute a
          materially adverse change in, or constitute a development involving a
          prospective materially adverse effect on or change in, the condition
          (financial or otherwise), earnings, properties, business affairs or
          business prospects, net worth or results of operations of the Company
          and its subsidiary, taken as a whole, except as described in or
          contemplated by the Prospectus.

          Other Agreements

               (xxix)  No default by the Company or its subsidiary, or to their
          knowledge, by another party, exists, and no event has occurred which,
          with notice or lapse of time or both, would constitute a default by
          the Company or its subsidiary, or to their knowledge, by another
          party, in the due performance and observance of any term, covenant or
          condition of any material indenture, mortgage, deed of trust, lease or
          other material agreement or instrument to which the Company or its
          subsidiary is a party or by which the Company or its subsidiary or any
          of their respective properties is bound.

          Absence of Materially Adverse Change

               (xxx)  Subsequent to the respective dates as of which information
          is given in the Registration Statement and the Prospectus, neither the
          Company nor its subsidiary has sustained any material loss or
          interference with its business as described in the Prospectus or
          properties from fire, flood, hurricane, accident or other calamity,
          whether or not covered by insurance, or from any labor dispute or any
          legal or governmental proceeding, and there has been no materially
          adverse change (including, without limitation, a change in management
          or control), or development involving a prospective materially adverse
          change, in the condition (financial or otherwise), management,
          earnings, property, business affairs or business prospects,
          stockholders' equity, net worth or results of operations of the
          Company or its subsidiary, taken as a whole, other than as described
          in or contemplated by the Prospectus (exclusive of any amendments or
          supplements thereto).

               (xxxi)  No receiver or liquidator (or similar person) has been
          appointed in respect of the Company or its subsidiary or in respect of
          any part of the assets of the

                                       18
<PAGE>
 
          Company or its subsidiary; no resolution, order of any court,
          regulatory body, governmental body or otherwise, or petition or
          application for an order, has been passed, made or presented for the
          winding up of the Company or its subsidiary or for the protection of
          the Company or its subsidiary from its creditors; and neither the
          Company nor its subsidiary has stopped or suspended payments of its
          debts, become unable to pay its debts or otherwise become insolvent.

          (b) As a further condition of the obligation of the Underwriters to
underwrite and pay for the Shares, each Selling Stockholder (including each
Principal Selling Stockholder), severally and not jointly, represents and
warrants to, and agrees with, each of the several Underwriters that:

               (i) Such Selling Stockholder has full power (corporate and other)
          to enter into this Agreement and to sell, assign, transfer and deliver
          to the Underwriters the Shares to be sold by such Selling Stockholder
          hereunder in accordance with the terms of this Agreement; the
          execution and delivery of this Agreement have been duly authorized by
          all necessary corporate action of such Selling Stockholder; and this
          Agreement has been duly executed and delivered by such Selling
          Stockholder.

               (ii) Such Selling Stockholder has duly executed and delivered a
          power of attorney and custody agreement (with respect to such Selling
          Stockholder, the "Power-of-Attorney" and the "Custody Agreement",
          respectively), each in the form heretofore delivered to the
          Representatives, appointing Mark R. Templeton and Robert D. Selvi as
          such Selling Stockholder's attorneys-in-fact (the "Attorney-in-Fact")
          with authority to execute, deliver and perform this Agreement on
          behalf of such Selling Stockholder and appointing First National Bank
          of Boston, as custodian thereunder (the "Custodian").  Certificates in
          negotiable form, endorsed in blank or accompanied by blank stock
          powers duly executed, with signatures appropriately guaranteed,
          representing the Shares to be sold by such Selling Stockholder
          hereunder have been deposited with the Custodian pursuant to the
          Custody Agreement for the purpose of delivery pursuant to this
          Agreement.  Such Selling Stockholder has full power (corporate and
          other) to enter into the Custody Agreement and the Power-of-Attorney
          and to perform its obligations under the Custody Agreement.  The
          execution and delivery of the Custody Agreement and the Power of
          Attorney have been duly authorized by all necessary corporate action
          of such Selling Stockholder; the Custody Agreement and the Power-of-
          Attorney have been duly executed and delivered by such Selling
          Stockholder and, assuming due authorization, execution and delivery by
          the Custodian, are the legal, valid, binding and enforceable
          instruments of such Selling Stockholder.  Such Selling Stockholder
          agrees that each of the Shares represented by the certificates on
          deposit with the Custodian is subject to the interests of the
          Underwriters hereunder, that the arrangements made for such custody,
          the appointment of the Attorney-in-Fact and the right, power and
          authority of the Attorney-in-Fact to execute and deliver this
          Agreement, to agree on the price at which the Shares (including such
          Selling Stockholder's Shares) are to be sold to the Underwriters, and
          to carry out the terms of this Agreement, are to that extent
          irrevocable and that the obligations of such Selling Stockholder
          hereunder shall not

                                       19
<PAGE>
 
          be terminated, except as provided in this Agreement or the Custody
          Agreement, by any act of such Selling Stockholder, by operation of law
          or otherwise, whether in the case of any individual Selling
          Stockholder by the death or incapacity of such Selling Stockholder, in
          the case of a trust or estate by the death of the trustee or trustees
          or the executor or executors or the termination of such trust or
          estate, or in the case of a corporate or partnership Selling
          Stockholder by its liquidation or dissolution or by the occurrence of
          any other event. If any individual Selling Stockholder, trustee or
          executor should die or become incapacitated or any such trust should
          be terminated, or if any corporate or partnership Selling Stockholder
          shall liquidate or dissolve, or if any other event should occur,
          before the delivery of such Shares hereunder, the certificates for
          such Shares deposited with the Custodian shall be delivered by the
          Custodian in accordance with the respective terms and conditions of
          this Agreement as if such death, incapacity, termination, liquidation
          or dissolution or other event had not occurred, regardless of whether
          or not the Custodian or the Attorney-in-Fact shall have received
          notice thereof.

               (iii)  Such Selling Stockholder is the lawful owner of the Shares
          to be sold by such Selling Stockholder hereunder and upon sale and
          delivery of, and payment for, such Shares, as provided herein, such
          Selling Stockholder will convey good and marketable title to such
          Shares, free and clear of any security interests, liens, encumbrances,
          equities, claims or other defects.

               (iv) Neither such Selling Stockholder nor any person acting on
          behalf of it has, directly or indirectly, (x) taken any action
          designed to cause or to result in, or that has constituted or which
          might reasonably be expected to constitute, the stabilization or
          manipulation of the price of any security of the Company to facilitate
          the sale or resale of the Shares or (y) since the filing of the
          Original Registration Statement (I) sold, bid for, purchased, or paid
          anyone any compensation for soliciting purchases of, the Shares or
          (II) paid or agreed to pay to any person any compensation for
          soliciting another to purchase any other securities of the Company
          (except for the sale of Shares by the Selling Stockholders under this
          Agreement).

               (v) Such Selling Stockholder has carefully reviewed this
          Agreement, the Prospectus and the Registration Statement, and the
          information regarding such Selling Stockholder set forth therein under
          the caption "Principal and Selling Stockholders" is complete and
          accurate.  All information furnished by or on behalf of such Selling
          Stockholder for use in the Registration Statement is, and on each
          Closing Date will be, true, correct, and complete, and does not, and
          on such Closing Date will not, contain any untrue statement of a
          material fact or omit to state any material fact necessary to make
          such information not misleading, and all information furnished in
          writing by or on behalf of such Selling Stockholder for use in the
          Prospectus is, and on such Closing Date will be, true, correct, and
          complete, and does not, and on such Closing Date will not, contain any
          untrue statement of a material fact or omit to state any material fact
          necessary to make such information not misleading in the light of the
          circumstances under which they were made.

               (vi) The sale by such Selling Stockholder of Shares pursuant
          hereto is not prompted by any adverse information concerning the
          Company or its subsidiary that is not set forth in the Registration
          Statement or the Prospectus.

               (vii)  The sale of the Shares to the Underwriters by such Selling
          Stockholder pursuant to this Agreement, the compliance by such Selling
          Stockholder with the other provisions of this Agreement, the Custody
          Agreement and the consummation of the other transactions herein
          contemplated do not (i) require the consent, approval, authorization,
          registration or qualification of or with any governmental authority,
          except such as have been obtained or made or such as may be required
          by  state securities or Blue Sky laws of the various states of the
          United States of America or such other U.S. jurisdictions or by the
          NASD and, if the Registration Statement is not effective under the
          Securities Act as of the time of execution hereof, such as may be
          required (and shall be obtained as provided in this Agreement) under
          the Securities Act, or (ii) conflict with or result in a breach or
          violation of any of the terms and provisions of, or constitute a
          default under any indenture, mortgage, deed of trust, lease or other
          agreement or instrument to which such Selling Stockholder or any of
          its subsidiaries is a party or by which such Selling Stockholder or
          any of its subsidiaries or any of their respective properties are
          bound, or any statute or any judgment, decree, order, rule or
          regulation of any court or other governmental authority or any
          arbitrator applicable to such Selling Stockholder or any of its
          subsidiaries.

               (viii)  Such Selling Stockholder has not distributed and, prior
          to the later of (x) any Closing Date and (y) the completion of the
          distribution of the Shares, will not distribute any offering material
          in connection with the offering other than the Registration Statement
          or any amendment thereto, any Preliminary Prospectus or the Prospectus
          or any amendment or supplement thereto.

          (c) The above representations and warranties shall be deemed to be

            --------- 

          (a) The Company agrees to indemnify and hold harmless each Underwriter
and each person, if any, who controls any Underwriter within the meaning of
Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), against any and all losses, claims,
damages or liabilities, joint or several, to which such Underwriter or such
controlling person may become subject under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon:

               (i) any untrue statement or alleged untrue statement made by the
               Company in Section 5 hereof,

                                       21
<PAGE>
 
               (ii) any untrue statement or alleged untrue statement of any
               material fact contained in the Registration Statement or any
               amendment thereto, any Preliminary Prospectus or the Prospectus
               or any amendment or supplement thereto, or

               (iii)  the omission or alleged omission to state in the
               Registration Statement or any amendment thereto, any Preliminary
               Prospectus or the Prospectus or any amendment or supplement
               thereto a material fact required to be stated therein or
               necessary to make the statements therein not misleading,

and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other costs or expenses reasonably incurred by such
Underwriter or such controlling person in connection with investigating,
defending against or appearing as a third-party witness in connection with any
such loss, claim, damage, liability or action; provided, however, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any untrue statement
or alleged untrue statement or omission or alleged omission made in the
Registration Statement or any amendment thereto, any Preliminary Prospectus, the
Prospectus or any amendment or supplement thereto in reliance upon and in
conformity with written information furnished to the Company by such Underwriter
through the Representatives specifically for use therein; and provided, further,
that the Company will not be liable to any Underwriter or any person controlling
such Underwriter with respect to any such untrue statement, alleged untrue
statement, omission or alleged omission made in any Preliminary Prospectus that
is corrected in the Prospectus or any amendment or supplement thereto if the
person asserting any such loss, claim, damage or liability purchased Shares from
such Underwriter but was not sent or given a copy of the Prospectus, as amended
or supplemented, in any case where such delivery of the Prospectus, as amended
or supplemented, was required by the Securities Act, unless such failure to
deliver the Prospectus, as amended or supplemented, was a result of
noncompliance by the Company with Section 3 hereof.  The indemnity provided for
in this Section 6 shall be in addition to any liability which the Company may
otherwise have.  The Company will not, without the prior written consent of the
Representatives, settle or compromise or consent to the entry of any judgment in
any pending or threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not any such Representatives
or any person who controls any such Representatives is a party to such claim,
action, suit or proceeding), unless such settlement, compromise or consent
includes an unconditional release of all of the Underwriters and such
controlling persons from all liability arising out of such claim, action, suit
or proceeding.

          (b) Each of the Principal Selling Stockholders, Daniel I. Rubin and
the Selling Stockholders affiliated with U.S. Venture Partners severally and not
jointly agrees to indemnify and hold harmless each Underwriter and each person,
if any, who controls any Underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, against any and all losses,
claims, damages or liabilities, joint or several, to which such Underwriter or
such controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement made by such Selling Stockholder in Section 5 hereof, and will
reimburse, as incurred, each Underwriter and each such controlling person for
any legal or other

                                       22
<PAGE>
 
costs or expenses reasonably incurred by such Underwriter or such controlling
person in connection with investigating, defending against or appearing as a
third-party witness in connection with any such loss, claim, damage, liability
or action; provided, however, that such Selling Stockholder will not be liable
in any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any untrue statement or alleged untrue statement
or omission or alleged omission made in the Registration Statement or any
amendment thereto, any Preliminary Prospectus, the Prospectus or any amendment
or supplement thereto in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through the
Representatives specifically for use therein. Notwithstanding any other
provision of this paragraph (b), no Selling Stockholder shall be liable for
indemnification hereunder in an aggregate amount exceeding the net proceeds
(before deducting expenses) received by such Selling Stockholder in respect of
the Shares sold by such Selling Stockholder to the Underwriters pursuant to this
Agreement. The indemnity provided for in this Section 6 shall be in addition to
any liability which the Selling Stockholders may otherwise have. The Selling
Stockholders will not, without the prior written consent of the Representatives,
settle or compromise or consent to the entry of any judgment in any pending or
threatened claim, action, suit or proceeding in respect of which indemnification
may be sought hereunder (whether or not any such Representatives or any person
who controls any such Representatives is a party to such claim, action, suit or
proceeding), unless such settlement, compromise or consent includes an
unconditional release of all of the Underwriters and such controlling persons
from all liability arising out of such claim, action, suit or proceeding.

          (c) Each of the Selling Stockholders other than the Principal Selling
Stockholders, Daniel I. Rubin and the Selling Stockholders affiliated with U.S.
Venture Partners severally and not jointly agrees to indemnify and hold harmless
each Underwriter and each person, if any, who controls any Underwriter within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act, against any and all losses, claims, damages or liabilities, joint or
several, to which such Underwriter or such controlling person may become subject
under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement made by such Selling
Stockholder in Section 5 hereof, and will reimburse, as incurred, each
Underwriter and each such controlling person for any legal or other costs or
expenses reasonably incurred by such Underwriter or such controlling person in
connection with investigating, defending against or appearing as a third-party
witness in connection with any such loss, claim, damage, liability or action;
provided, however, that to the extent that such loss, claim, damage, liability
or action arises out of or is based upon Section 5(b)(v), such Selling
Stockholder will be liable in any such case only to the extent that any such
loss, claim, damage or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
the Registration Statement or any amendment thereto, any Preliminary Prospectus,
the Prospectus or any amendment or supplement thereto in reliance upon and in
conformity with written information relating to such Selling Stockholder
furnished to the Company by or on behalf of such Selling Stockholder
specifically for use therein.  Notwithstanding any other provision of this
paragraph (b), no Selling Stockholder shall be liable for indemnification
hereunder in an aggregate amount exceeding the net proceeds (before deducting
expenses) received by such Selling Stockholder in respect of the Shares sold by
such Selling Stockholder to the Underwriters pursuant to this Agreement.  The
indemnity provided for in this Section 6 shall be in addition to any liability
which the Selling Stockholders may otherwise have.  The Selling Stockholders
will not, without the prior

                                       23
<PAGE>
 
written consent of the Representatives, settle or compromise or consent to the
entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification may be sought hereunder (whether
or not any such Representatives or any person who controls any such
Representatives is a party to such claim, action, suit or proceeding), unless
such settlement, compromise or consent includes an unconditional release of all
of the Underwriters and such controlling persons from all liability arising out
of such claim, action, suit or proceeding.

          (d) Each Underwriter, severally and not jointly, agrees to indemnify
and hold harmless the Company, each of its directors, each of its officers who
signed the Registration Statement, each Selling Stockholder and each person, if
any, who controls the Company or such Selling Stockholder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act against any
losses, claims, damages or liabilities to which the Company or any such director
or officer of the Company, such Selling Stockholder or any such controlling
person of the Company or such Selling Stockholder may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement or any amendment thereto, any Preliminary
Prospectus or the Prospectus or any amendment or supplement thereto or (ii) the
omission or the alleged omission to state in the Registration Statement or any
amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto a material fact required to be stated therein or necessary
to make the statements therein not misleading, in each case to the extent, but
only to the extent, that such untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company by such Underwriter through the
Representatives specifically for use therein, and, subject to the limitation set
forth immediately preceding this clause, will reimburse, as incurred, any legal
or other expenses reasonably incurred by the Company or any such director,
officer or controlling person or such Selling Stockholder or controlling person
of such Selling Stockholder in connection with investigating, defending against
or appearing as a third-party witness in connection with any such loss, claim,
damage, liability or any action in respect thereof.  The indemnity provided in
this Section 6 will be in addition to any liability which any Underwriter may
otherwise have.  The Underwriters will not, without the prior written consent of
the Company, settle or compromise or consent to the entry of any judgment in any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not the Company or any
person who controls the Company is a party to such claim, action, suit or
proceeding), unless such settlement, compromise or consent includes an
unconditional release of the Company and such controlling persons from all
liability arising out of such claim, action, suit or proceeding.  The remedies
provided for in this Section 6 are not exclusive and shall not limit any rights
or remedies which may otherwise be available to any indemnified party at law or
in equity.

          (e) In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to paragraph (a), (b), (c) or (d) of this Section 6, such person
(for purposes of this paragraph (e), the "indemnified party") shall, promptly
after receipt by such party of notice of the commencement of such action, notify
the person against whom such indemnity may be sought (for purposes of this
paragraph (d), the "indemnifying party"), but the omission so to notify the
indemnifying party will not relieve it from any liability which it may have to
any indemnified party otherwise than under this Section 6.

                                       24
<PAGE>
 
In case any such action is brought against any indemnified party, and it
notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party;
provided, however, that if the defendants in any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses available
to it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnifying party shall not have
the right to direct the defense of such action on behalf of such indemnified
party or parties and such indemnified party or parties shall have the right to
select separate counsel to defend such action on behalf of such indemnified
party or parties. After notice from the indemnifying party to such indemnified
party of its election so to assume the defense of any such action and approval
by such indemnified party of counsel appointed to defend such action, the
indemnifying party will not be liable to such indemnified party under this
Section 6 for any legal or other expenses, other than reasonable costs of
investigation, subsequently incurred by such indemnified party in connection
with the defense thereof, unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that in connection with such action the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (in addition to local counsel) in any one action or separate
but substantially similar actions in the same jurisdiction arising out of the
same general allegations or circumstances, designated in writing by the
Representatives in the case of paragraph (a), (b) or (c) of this Section 6,
representing the indemnified parties under such paragraph (a), (b) or (c) who
are parties to such action or actions), or (ii) the indemnifying party does not
promptly retain counsel satisfactory to the indemnified party, or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party. All fees and expenses reimbursed
pursuant to this paragraph (e) shall be reimbursed as they are incurred. After
such notice from the indemnifying party to such indemnified party, the
indemnifying party will not be liable for the costs and expenses of any
settlement of such action effected by such indemnified party without the consent
of the indemnifying party.

          (f) In circumstances in which the indemnity agreement provided for in
the preceding paragraphs of this Section 6 is unavailable or insufficient, for
any reason, to hold harmless an indemnified party in respect of any losses,
claims, damages or liabilities (or actions in respect thereof), each
indemnifying party, in order to provide for just and equitable contribution,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect (i) the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the Offering or (ii) if the allocation
provided by the foregoing clause (i) is not permitted by applicable law, not
only such relative benefits but also the relative fault of the indemnifying
party or parties on the one hand and the indemnified party on the other in
connection with the statements or omissions or alleged statements or omissions
that resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations.  The
relative benefits received by the Company and the Selling Stockholders on the
one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total proceeds from the Offering (before deducting expenses)
received by the Company and the Selling Stockholders bear to the total
underwriting discounts and commissions

                                       25
<PAGE>
 
received by the Underwriters. The relative fault of the parties shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, the Selling
Stockholders or the Underwriters, the parties' relative intents, knowledge,
access to information and opportunity to correct or prevent such statement or
omission, and any other equitable considerations appropriate in the
circumstances. The Company, the Selling Stockholders and the Underwriters agree
that it would not be equitable if the amount of such contribution were
determined by pro rata or per capita allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
that does not take into account the equitable considerations referred to above
in this paragraph (f). Notwithstanding any other provision of this paragraph
(f), no Underwriter shall be obligated to make contributions hereunder that in
the aggregate exceed the total public offering price of the Shares purchased by
such Underwriter under this Agreement, less the aggregate amount of any damages
that such Underwriter has otherwise been required to pay in respect of the same
or any substantially similar claim, and no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations to contribute
hereunder are several in proportion to their respective underwriting obligations
and not joint, and contributions among Underwriters shall be governed by the
provisions of the Deutsche Morgan Grenfell Inc. Master Agreement Among
Underwriters. For purposes of this paragraph (f), each person, if any, who
controls an Underwriter within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act shall have the same rights to contribution as
such Underwriter, and each director of the Company, each officer of the Company
who signed the Registration Statement and each person, if any, who controls the
Company or any Selling Stockholder within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, shall have the same rights to
contribution as the Company or such Selling Stockholder, as the case may be.

Section 7.  Conditions Precedent.   The obligations of the several Underwriters
            --------------------

Company and the Selling Stockholders contained herein as of the date hereof and

City time on the date of determination of the public offering price, if such
determination occurred at or prior to 4:30 P.M. New York City time on such date,
or 12:00 Noon New York City time on the business day following the day on which
the public offering price was determined, if such determination occurred after
4:30 P.M. New York City time on such date, and (ii) if the Company has elected
to rely upon Rule 462(b), the Rule 462(b) Registration Statement shall have been
declared effective not later than the time confirmations are sent or given as
specified by Rule 462(b)(2), or such later time and date as shall have been
consented to by the

                                       26
<PAGE>
 
Representatives; if required, the Prospectus or any Term Sheet that constitutes
a part thereof and any amendment or supplement thereto shall have been filed
with the Commission in the manner and within the time period required by Rules
434 and 424(b) under the Securities Act; no stop order suspending the
effectiveness of the Registration Statement or any amendment thereto shall have

contemplated by the Commission; and the Company shall have complied with any
request of the Commission for additional information (to be included in the
Registration Statement or the Prospectus or otherwise).

          (b) The Representatives shall have received a legal opinion from
Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel for the
Company, dated the Closing Date, to the effect that:

               (i) the Registration Statement is effective under the Securities
               Act; any required filing of the Prospectus, or any Term Sheet
               that constitutes a part thereof, pursuant to Rules 434 and 424(b)
               has been made in the manner and within the time period required
               by Rules 434 and 424(b); and no stop order suspending the
               effectiveness of the Registration Statement or any amendment
               thereto has been issued and, to the best knowledge of such
               counsel, no proceedings for that purpose are pending or
               threatened by the Commission;

               (ii) the Original Registration Statement and each amendment
               thereto, any Rule 462(b) Registration Statement and the
               Prospectus (in each case, other than the financial statements,
               including the notes thereto, schedule and other financial
               information contained therein, as to which such counsel need
               express no opinion) comply as to form in all material respects
               with the applicable requirements of the Securities Act and the
               rules and regulations of the Commission thereunder;

               (iii)  such counsel has no reason to believe that (in each case,
               other than the financial statements, including the notes thereto,
               schedule and other financial information contained therein, as to
               which such counsel need express no opinion) (x) the Registration
               Statement, as of its effective date, contained any untrue
               statement of a material fact or omitted to state a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading or (y) the Prospectus, as of its date or
               the date of such opinion, included or includes any untrue
               statement of a material fact or omitted or omits to state a
               material fact necessary in order to make the statements therein,
               in the light of the circumstances under which they were made, not
               misleading.

               (iv) if the Company elects to rely on Rule 434 under the
               Securities Act, the Prospectus is not "materially different", as
               such term is used in Rule 434, from the prospectus included in
               the Registration Statement at the time of its effectiveness or an
               effective post-effective amendment thereto (including

                                       27
<PAGE>
 
               such information that is permitted to be omitted pursuant to Rule
               430A under the Securities Act);

               (v) the Company has an authorized, issued and outstanding
               capitalization as set forth in the Prospectus as of the dates
               stated therein; all of the issued shares of capital stock of the
               Company have been duly authorized and validly issued and are
               fully paid and nonassessable, have been issued in compliance with
               all applicable federal and state securities laws and were not
               issued in violation of or subject to any preemptive rights or
               other rights to subscribe for or purchase securities; the Shares
               have been duly authorized by all necessary corporate action of
               the Company and, when issued and delivered to and paid for by the
               Underwriters pursuant to this Agreement, will be validly issued,
               fully paid and nonassessable; no holders of outstanding shares of
               capital stock of the Company are entitled as such to any
               preemptive or other rights to subscribe for any of the Shares;

               has not been fully exercised or waived to require the Company to
               register the offer or sale of any securities owned by such holder
               under the Securities Act in the Offering contemplated by this
               Agreement;

               (vi) all of the Shares have been duly authorized and accepted for

               are duly qualified to transact business as foreign corporations
               and are in good standing under the laws of all other
               jurisdictions where the ownership, leasing or operation of their
               respective properties or assets or the conduct of their
               respective businesses requires such qualification, except where
               the failure to be so qualified does not amount to a material
               liability or disability to the Company and its subsidiary, taken
               as a whole; the Company and its subsidiary have full power and
               authority to own, lease and operate their respective properties
               and assets and conduct their respective businesses as described
               in the Registration Statement and the Prospectus, and the Company

               beneficially by the Company free and clear of any perfected
               security interests or, to the best knowledge of such counsel, any
               other security interests, liens, encumbrances, equities or
               claims;

               (viii)  the statements set forth under the heading "Description
               of Capital Stock" in the Prospectus, insofar as such statements
               purport to summarize certain provisions of the capital stock of
               the Company, provide a fair summary of such provisions; and the
               statements set forth under the headings

          (c) The Representatives shall have received a legal opinion from

               (i) such Selling Stockholder has full power (corporate and other)
               to enter into this Agreement, the Custody Agreement and the
               Power-of-Attorney and to sell, assign, transfer and deliver the
               Shares being sold by such Selling Stockholder hereunder in the
               manner provided in this Agreement and to perform its obligations
               under the Custody Agreement; the execution and delivery of this
               Agreement, the Custody Agreement and the Power of Attorney have
               been duly authorized by all necessary action of each Selling
               Stockholder; this Agreement, the Custody Agreement and the Power-
               of-Attorney have been duly executed and delivered by each Selling
               Stockholder; assuming due authorization, execution and delivery
               by the Custodian, the Custody Agreement and the Power-of-Attorney
               are the legal, valid, binding and enforceable instruments of such
               Selling Stockholder, subject to applicable bankruptcy, insolvency
               and similar laws affecting creditors' rights generally and
               subject, as to enforceability, to general principles of equity
               (regardless of whether enforcement is sought in a proceeding in
               equity or at law);

               (ii) the delivery by each Selling Stockholder to the several
               Underwriters of certificates for the Shares being sold hereunder
               by such Selling Stockholder against payment therefor as provided
               herein, will convey good and marketable title to such Shares to
               the several Underwriters, free and clear of all security
               interests, liens, encumbrances, equities, claims or other
               defects;

               (iii)  the sale of the Shares to the Underwriters by such Selling
               Stockholder pursuant to this Agreement, the compliance by such
               Selling Stockholder with the other provisions of this Agreement

               Agreement and the consummation of the other transactions herein
               contemplated do not (x) require the consent, approval,
               authorization, registration or qualification of or with any
               governmental authority, except such as have been obtained and
               such as may be required under state securities or Blue Sky laws,
               or (y) conflict with or result in a breach or violation of any of
               the terms and provisions of, or constitute a default under any
               indenture, mortgage, deed of trust, lease or other agreement or
               instrument to which, to the best of such counsel's knowledge,
               such Selling Stockholder or any of its subsidiaries is a party or
               by which such Selling Stockholder or any of its subsidiaries or
               any of their respective properties are bound, or the charter
               documents or bylaws of such Selling Stockholder or any of its
               subsidiaries or any statute, rule or regulation or, to the best
               of such counsel's knowledge, any judgment, decree, order of any
               court or other governmental authority or any arbitrator
               applicable to such Selling Stockholder or any of its
               subsidiaries.

          In rendering such opinion, such counsel may rely, as to matters of
fact, to the extent such counsel deems proper, on certificates of the Selling
Stockholders and public officials and, as to matters involving the application
of laws of any jurisdiction other than the State of California or the United
States, to the extent satisfactory in form and scope to counsel for the
Underwriters, upon the opinion of local counsel.  The foregoing opinion shall
also state that the Underwriters are justified in relying upon such opinion of
such local counsel, and copies of such opinion shall be delivered to the
Representatives and counsel for the Underwriters.

          References to the Registration Statement and the Prospectus in this
paragraph (c) shall include any amendment or supplement thereto at the date of
such opinion.

          (d) The Representatives shall have received a legal opinion from

Prospectus, and such other related matters as the Representatives may reasonably
require, and the Company shall have furnished to such counsel such documents as
they may reasonably request for the purpose of enabling them to pass upon such
matters.

          (e) The Representatives shall have received from Coopers & Lybrand
L.L.P. a letter or letters dated, respectively, the date hereof and the Closing
Date, in form and substance satisfactory to the Representatives, to the effect
that:

               (i) they are independent accountants with respect to the Company
               and its subsidiary within the meaning of the Securities Act and
               the applicable rules and regulations thereunder;

               (ii) in their opinion, the audited financial statements and
               schedule examined by them and included in the Registration
               Statement and the Prospectus comply in form in all material
               respects with the applicable accounting requirements of the
               Securities Act and the related published rules and regulations;

               (iii)  on the basis of a reading of the latest available interim
               unaudited consolidated financial statements of the Company,
               carrying out certain specified procedures (which do not
               constitute an examination made in accordance with generally
               accepted auditing standards) that would not necessarily reveal
               matters of significance with respect to the comments set forth in
               this paragraph (iii), a reading of the minute books of the
               stockholders, the board of directors and any committees thereof
               of the Company and its subsidiary, and inquiries of certain
               officials of the Company and its subsidiary who have
               responsibility for financial and accounting matters, nothing came
               to their attention that caused them to believe that:

                    (x) the unaudited consolidated financial statements of the
                    Company and its subsidiary included in the Registration
                    Statement and the Prospectus do not comply in form in all
                    material respects with the applicable accounting
                    requirements of the Securities Act and the related published
                    rules and regulations thereunder or are not in conformity
                    with GAAP applied on a basis substantially consistent with
                    that of the audited financial statements included in the
                    Registration Statement and the Prospectus;

                    (y) at a specific date not more than five business days
                    prior to the date of such letter, there were any changes in
                    the capital stock or long-term debt of the Company or any
                    decreases in net current assets or stockholders' equity of
                    the Company, in each case compared with amounts shown on the
                    March 31, 1998 balance sheet included in the Registration
                    Statement and the Prospectus, or for the period from April
                    1, 1998 to such specified date there were any decreases, as
                    compared with a period of comparable length commencing on
                    April 1, 1997, in revenue, net income before provision for
                    income taxes or total or per share amounts of net income of
                    the Company, except in all instances for changes, decreases
                    or increases set forth in such letter.

               (iv) they have carried out certain specified procedures, not
               constituting an audit, with respect to certain amounts,
               percentages and financial information that are derived from the
               general accounting records of the Company and are included in the
               Registration Statement and the Prospectus under the captions
               "Prospectus Summary," "Risk Factors," "Use of Proceeds,"
               "Capitalization," "Dilution," "Selected Financial Data,"
               "Management's Discussion and Analysis of Financial Condition and
               Results of Operations," "Business," "Management," "Certain
               Transactions," "Principal and Selling Stockholders," "Description
               of Capital Stock," "Shares Eligible for Future Sales" and "Item
               15.  Recent Sales of Unregistered Securities" and in Exhibit
               11.01 to the Registration Statement, and have compared such
               amounts, percentages and financial information with such records
               of the Company and with information derived from such records and
               have found them to be in agreement, excluding any questions of
               legal interpretation.

          In the event that the letters referred to above set forth any such
changes, decreases or increases, it shall be a further condition to the
obligations of the Underwriters that (I) such letters shall be accompanied by a
written explanation of the Company as to the significance thereof, unless the
Representatives deem such explanation unnecessary, and (II) such changes,
decreases or increases do not, in the sole judgment of the Representatives, make
it impractical or inadvisable to proceed with the purchase and delivery of the
Shares as contemplated by the Registration Statement, as amended as of the date
hereof.  References to the Registration Statement and the Prospectus in this
paragraph (e) with respect to either letter referred to above shall include any

               fact necessary in order to make the statements therein, in the
               light of the circumstances under which they were made, not
               misleading; and the Company has performed all covenants and
               agreements and satisfied all conditions on its part to be
               performed or satisfied at or prior to the Closing Date;

               (ii) no stop order suspending the effectiveness of the
               Registration Statement or any amendment thereto has been issued,
               and no proceedings for that purpose have been instituted or

               involving a prospective materially adverse change, in the
               condition (financial or otherwise), management, earnings,
               properties, business affairs or business prospects, stockholders'
               equity, net worth or results of operations of the Company or its

persons (who may include one or more of the non-defaulting Underwriters,
including the Representatives), but if no such arrangements are made by the
First Closing Date or the related Option Closing Date, as the case may be, the
other Underwriters shall be obligated severally in the proportions that the
number of Firm Shares set forth opposite their respective names in Schedule 1
hereto bears to the aggregate number of Firm Shares set forth opposite the names
of all such non-defaulting Underwriters, or in such other proportions as the
Representatives may specify, to purchase the Shares which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase on such
date.  If, at the First Closing, any Underwriter or Underwriters shall fail or
refuse to purchase Firm Shares and the aggregate number of Firm Shares with
respect to which such default occurs is more than ten per cent of the aggregate
number of Firm Shares to be purchased, and arrangements satisfactory to the
Representatives, the Company and the Selling Stockholders for the purchase of
such Firm Shares are not made within 36 hours after such default, this Agreement
shall terminate without liability on the part of any non-defaulting Underwriter,
the Company or any Selling Stockholder.  In any such case either the
Representatives or the Company shall have the right to postpone the Closing, but
in no event for longer than seven days, in order that the required changes, if
any, in the Registration Statement and in the Prospectus or in any other
documents or arrangements may be effected.  If, at any Option Closing, any
Underwriter or Underwriters shall fail or refuse to purchase Option Shares, the
non-defaulting Underwriters shall have the option to (i) terminate their
obligation hereunder to purchase Option Shares or (ii) purchase not less than
the number of Option Shares that such non-defaulting

                                       35
<PAGE>
 
Underwriters would have been obligated to purchase in the absence of such
default. As used in this Agreement, the term "Underwriter" includes any person
substituted for an Underwriter under this Section 8. Any action taken under this
Section 8 shall not relieve any defaulting Underwriter from liability in respect
of any default of such Underwriter under this Agreement.

Section 9.  Termination.  This Agreement shall be subject to termination in the
            -----------                                                        
sole discretion of the Representatives by notice to the Company and the Selling
Stockholders given prior to any Closing Date in the event that the Company or
any Selling Stockholder shall have failed, refused or been unable to perform all
obligations and satisfy all conditions on its part to be performed or satisfied
hereunder at or prior thereto or,  if at or prior to any Closing Date, (a)
trading in securities generally on the New York Stock Exchange or the Nasdaq
National Market shall have been suspended or materially limited or minimum or
maximum prices shall have been established by or on, as the case may be, the
Commission or the New York Stock Exchange or the Nasdaq National Market; (b)
trading of any securities of the Company shall have been suspended on any
exchange or in any over-the-counter market; (c) a general moratorium on
commercial banking activities shall have been declared by Federal, New York
State or California authorities; (d) there shall have occurred (i) an outbreak
or escalation of hostilities between the United States and any foreign power,
(ii) an outbreak or escalation of any other insurrection or armed conflict
involving the United States, or (iii) any other calamity or crisis or materially
adverse change in general economic, political or financial conditions having an
effect on the U.S. financial markets that, in the sole judgment of the
Representatives, makes it impractical or inadvisable to proceed with the public
offering or the delivery of the Shares as contemplated by the Registration
Statement, as amended as of the date hereof; or (e) the Company or its
subsidiary shall have, in the sole judgment of the Representatives, sustained
any material loss or interference with their respective businesses as described
in the Prospectus or properties from fire, flood, hurricane, accident or other
calamity, whether or not covered by insurance, or from any labor dispute or any
legal or governmental proceeding, or there shall have been any materially
adverse change (including, without limitation, a change in management or
control), or constitute a development involving a prospective materially adverse
change, in the condition (financial or otherwise), management, earnings,
properties, business affairs or business prospects, stockholders' equity, net
worth or results of operations of the Company or its subsidiary, except in each
case as described in or contemplated by the Prospectus (exclusive of any
amendment or supplement thereto).  Termination of this Agreement pursuant to
this Section 9 shall be without liability of any party to any other party except
for the liability of the Company in relation to expenses as provided in Sections
4 and 10 hereof, the liability of the Selling Stockholders in relation to
expenses as provided in Sections 4 and 10 hereof, the indemnity provided in
Section 6 hereof and any liability arising before or in relation to such
termination.

Section 10.  Reimbursement of Expenses.  If the sale of the Shares provided for
             -------------------------                                         
herein is not consummated because any condition to the obligations of the
Underwriters set forth in Section 7 hereof is not satisfied or because of any
termination pursuant to Section 9 hereof (other than by reason of a default by
any of the Underwriters), the Company shall reimburse the Underwriters,
severally upon demand, for all out-of-pocket expenses (including fees and
disbursements of counsel) that shall have been incurred by them in connection
with the proposed purchase and sale of the Shares.  If the Company is required
to make any payments to the Underwriters under this Section 10 because of any
Selling Stockholder's refusal, inability or failure to satisfy any condition to
the obligations of the Underwriters set forth in Section 7 hereof, such
defaulting Selling

Stockholder, pro rata in proportion to the percentage of Shares to be sold by
             --- ----
each, shall reimburse the Company on demand for all amounts so paid.

Section 11.  Information Supplied by Underwriters.  The statements set forth in
             ------------------------------------

in any Preliminary Prospectus or the Prospectus (to the extent such statements
relate to the Underwriters) constitute the only information furnished by any
Underwriter through the Representatives to the Company for the purposes of
Section 5(a)(ii) and Section 6 hereof.  The Underwriters confirm that such

          (e) This Agreement shall inure to the benefit of and shall be binding
upon the several Underwriters, the Company, the Selling Stockholders and their
respective successors and legal representatives, and nothing expressed or
mentioned in this Agreement is intended or shall be construed to give any other

Agreement, or any provisions herein contained, this Agreement and all conditions
and provisions hereof being intended to be and being for the sole and exclusive
benefit of such persons and for the benefit of no other person, except that (i)

provisions of this Agreement be enforced to the fullest extent permissible under
the law and public policies applied in each jurisdiction in which enforcement is
sought.  Accordingly, in the event that any provision of this Agreement would be
held in any jurisdiction to be invalid, prohibited or unenforceable for any
reason, such provision, as to such jurisdiction, shall be ineffective, without
invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of such provision in any other jurisdiction.

Section 15.  Governing Law.  The validity and interpretation of this Agreement,
             -------------

(Multicurrency-Cross Border)

                 International Swap Dealers Association, Inc.

                                MASTER AGREEMENT

                            dated as of ___________


__________________________________ and______________________________________
have entered and/or anticipate entering into one or more transactions (each a
"Transaction") that are or will be governed by this Master Agreement, which
includes the schedule (the "Schedule"), and the documents and other confirming
evidence (each a "Confirmation") exchanged between the parties confirming those
Transactions.

Accordingly, the parties agree as follows:-

1.   INTERPRETATION

(a)  DEFINITIONS. The terms defined in Section 14 and in the Schedule will
have the meanings therein specified for the purpose of this Master Agreement.

(b)  INCONSISTENCY. In the event of any inconsistency between the provisions
of the Schedule and the other provisions of this Master Agreement, the Schedule
will prevail. In the event of any inconsistency between the provisions of any
Confirmation and this Master Agreement (including the Schedule), such
Confirmation will prevail for the purpose of the relevant Transaction.

(c)  SINGLE AGREEMENT. All Transactions are entered into in reliance on the fact
that this Master Agreement and all Confirmations form a single agreement between
the parties (collectively referred to as this "Agreement"), and the parties
would not otherwise enter into any Transactions.

2.   OBLIGATIONS

(a)  GENERAL CONDITIONS.

     (i) Each party will make each payment or delivery specified in each 
     Confirmation to be made by it, subject to the other provisions of this 
     Agreement.

     (ii) Payments under this Agreement will be made on the due date for value
     on that date in the place of the account specified in the relevant
     Confirmation or otherwise pursuant to this Agreement, in freely
     transferable funds and in the manner customary for payments in the required
     currency. Where settlement is by delivery (that is, other than by payment),
     such delivery will be made for receipt on the due date in the manner
     customary for the relevant obligation unless otherwise specified in the
     relevant Confirmation or elsewhere in this Agreement.

     (iii) Each obligation of each party under Section 2(a)(i) is subject to (1)
     the condition precedent that no Event of Default or Potential Event of
     Default with respect to the other party has occurred and is continuing, (2)
     the condition precedent that no Early Termination Date in respect of the
     relevant Transaction has occurred or been effectively designated and (3)
     each other applicable condition precedent specified in this Agreement.

<PAGE>
 
(b)  CHANGE OF ACCOUNT. Either party may change its account for receiving a
payment or delivery by giving notice to the other party at least five Local
Business Days prior to the scheduled date for the payment or delivery to which
such change applies unless such other party gives timely notice of a reasonable
objection to such change.

(c)  NETTING.  If on any date amounts would otherwise be payable:-

     (i)   in the same currency; and

     (ii)  in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation to make
payment of any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by one party
exceeds the aggregate amount that would otherwise have been payable by the other
party, replaced by an obligation upon the party by whom the larger aggregate
amount would have been payable to pay to the other party the excess of the
larger aggregate amount over the smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net amount
will be determined in respect of all amounts payable on the same date in the
same currency in respect of such Transactions, regardless of whether such
amounts are payable in respect of the same Transaction. The election may be made
in the Schedule or a Confirmation by specifying that subparagraph (ii) above
will not apply to the Transactions identified as being subject to the election,
together with the starting date (in which case subparagraph (ii) above will not,
or will cease to, apply to such Transactions from such date). This election may
be made separately for different groups of Transactions and will apply
separately to each pairing of Offices through which the parties make and receive
payments or deliveries.

(d)  DEDUCTION OR WITHHOLDING FOR TAX.

     (i) Gross-Up. All payments under this Agreement will be made without any
     deduction or withholding for or on account of any Tax unless such deduction
     or withholding is required by any applicable law, as modified by the
     practice of any relevant governmental revenue authority, then in effect.
     If a party is so required to deduct or withhold, then that party ("X")
     will:-

          (1) promptly notify the other party ("Y") of such requirement;

          (2) pay to the relevant authorities the full amount required to be
          deducted or withheld (including the full amount required to be
          deducted or withheld from any additional amount paid by X to Y under
          this Section 2(d)) promptly upon the earlier of determining that such
          deduction or withholding is required or receiving notice that such
          amount has been assessed against Y;

          (3) promptly forward to Y an official receipt (or a certified copy),
          or other documentation reasonably acceptable to Y, evidencing such
          payment to such authorities; and

          (4) if such Tax is an Indemnifiable Tax, pay to Y, in addition to the
          payment to which Y is otherwise entitled under this Agreement, such
          additional amount as is necessary to ensure that the net amount
          actually received by Y (free and clear of Indemnifiable Taxes, whether
          assessed against X or Y) will equal the full amount Y would have
          received had no such deduction or withholding been required. However,
          X will not be required to pay any additional amount to Y to the extent
          that it would not be required to be paid but for:-

          (A) the failure by Y to comply with or perform any agreement contained
          in Section 4(a)(i), 4(a)(iii) or 4(d); or

          (B) the failure of a representation made by Y pursuant to Section 3(f)
          to be accurate and true unless such failure would not have occurred
          but for (I) any action taken by a taxing authority, or brought in a
          court of competent jurisdiction, on or after the date on which a
          Transaction is entered into (regardless of whether such action is
          taken or brought with respect to a party to this Agreement) or (II) a
          Change in Tax Law.

                                       2
<PAGE>
 
     (ii) LIABILITY.  If:-

          (1) X is required by any applicable law, as modified by the practice
          of any relevant governmental revenue authority, to make any deduction
          or withholding in respect of which X would not be required to pay an
          additional amount to Y under Section 2(d)(i)(4);

          (2) X does not so deduct or withhold; and

          (3) a liability resulting from such Tax is assessed directly 
          against X,

     then, except to the extent Y has satisfied or then satisfies the liability
     resulting from such Tax, Y will promptly pay to X the amount of such
     liability (including any related liability for interest, but including any
     related liability for penalties only if Y has failed to comply with or
     perform any agreement contained in Section 4(a)(i), 4(a)(iii) or 4(d)).

(e)  DEFAULT INTEREST; OTHER AMOUNTS. Prior to the occurrence or effective
     designation of an Early Termination Date in respect of the relevant
     Transaction, a party that defaults in the performance of any payment
     obligation will, to the extent permitted by law and subject to Section
     6(c), be required to pay interest (before as well as after judgment) on the
     overdue amount to the other party on demand in the same currency as such
     overdue amount, for the period from (and including) the original due date
     for payment to (but excluding) the date of actual payment, at the Default
     Rate. Such interest will be calculated on the basis of daily compounding
     and the actual number of days elapsed. If, prior to the occurrence or
     effective designation of an Early Termination Date in respect of the
     relevant Transaction, a party defaults in the performance of any obligation
     required to be settled by delivery, it will compensate the other party on
     demand if and to the extent provided for in the relevant Confirmation or
     elsewhere in this Agreement.

3.   REPRESENTATIONS

Each party represents to the other party (which representations will be deemed
to be repeated by each party on each date on which a Transaction is entered into
and, in the case of the representations in Section 3(f), at all times until the
termination of this Agreement) that:-

(a)  BASIC REPRESENTATIONS.

          all obligations of such party under each Transaction to which such
          Credit Support Document relates without the written consent of the
          other party; or

          (3) the party or such Credit Support Provider disaffirms, disclaims,

     Agreement or any Credit Support Document proves to have been incorrect or
     misleading in any material respect when made or repeated or deemed to have
     been made or repeated;

     (v) DEFAULT UNDER SPECIFIED TRANSACTION. The party, any Credit Support
     Provider of such party or any applicable Specified Entity of such party (1)

     taken by any person or entity appointed or empowered to operate it or act
     on its behalf;

     (vi) CROSS DEFAULT.  If "Cross Default" is specified in the Schedule as
     applying to the party, the occurrence or existence of (1) a default, event
     of default or other similar condition or event (however

                                       5
<PAGE>
 
     described) in respect of such party, any Credit Support Provider of such
     party or any applicable Specified Entity of such party under one or more
     agreements or instruments relating to Specified Indebtedness of any of them
     (individually or collectively) in an aggregate amount of not less than the
     applicable Threshold Amount (as specified in the Schedule) which has

     such time of being declared, due and payable under such agreements or
     instruments, before it would otherwise have been due and payable or (2) a
     default by such party, such Credit Support Provider or such Specified
     Entity (individually or collectively) in making one or more payments on the
     due date thereof in an aggregate amount of not less than the applicable
     Threshold Amount under such agreements or instruments (after giving effect
     to any applicable notice requirement or grace period);

     (vii) BANKRUPTCY.  The party, any Credit Support Provider of such party or
     any applicable Specified Entity of such party:-

       (1) is dissolved (other than pursuant to a consolidation, amalgamation or

       law affecting creditors' rights, or a petition is presented for its
       winding-up or liquidation, and, in the case of any such proceeding or
       petition instituted or presented against it, such proceeding or petition
       (A) results in a judgment of insolvency or bankruptcy or the entry of an
       order for relief or the making of an order for its winding-up or
       liquidation or (B) is not dismissed, discharged, stayed or restrained in
       each case within 30 days of the institution or presentation thereof; (5)

       furtherance of, or indicating its consent to, approval of, or
       acquiescence in, any of the foregoing acts; or

     Provider of such party consolidates or amalgamates with, or merges with or
     into, or transfers all or substantially all its assets to, another entity
     and, at the time of such consolidation, amalgamation, merger or transfer:-

       (1) the resulting, surviving or transferee entity fails to assume all the
       obligations of such party or such Credit Support Provider under this
       Agreement or any Credit Support Document to which it or its predecessor
       was a party by operation of law or pursuant to an agreement reasonably
       satisfactory to the other party to this Agreement; or

       (2) the benefits of any Credit Support Document fail to extend (without
       the consent of the other party) to the performance by such resulting,
       surviving or transferee entity of its obligations under this Agreement.

(b) TERMINATION EVENTS. The occurrence at any time with respect to a party or,
if applicable, any Credit Support Provider of such party or any Specified Entity
of such party of any event specified below constitutes an Illegality if the
event is specified in (i) below, a Tax Event if the event is specified in (ii)
below or a Tax Event Upon Merger if the event is specified in (iii) below, and,
if specified to be applicable, a Credit Event

                                       6
<PAGE>
 
Upon Merger if the event is specified pursuant to (iv) below or an Additional
Termination Event if the event is specified pursuant to (v) below:-

     (i) ILLEGALITY. Due to the adoption of, or any change in, any applicable
     law after the date on which a Transaction is entered into, or due to the
     promulgation of, or any change in, the interpretation by any court,
     tribunal or regulatory authority with competent jurisdiction of any
     applicable law after such date, it becomes unlawful (other than as a result
     of a breach by the party of Section 4(b)) for such party (which will be the
     Affected Party):-

          (1) to perform any absolute or contingent obligation to make a payment
          or delivery or to receive a payment or delivery in respect of such
          Transaction or to comply with any other material provision of this
          Agreement relating to such Transaction; or

          (2) to perform, or for any Credit Support Provider of such party to
          perform, any contingent or other obligation which the party (or such
          Credit Support Provider) has under any Credit Support Document
          relating to such Transaction;

     (ii) TAX EVENT. Due to (x) any action taken by a taxing authority, or
     brought in a court of competent jurisdiction, on or after the date on which
     a Transaction is entered into (regardless of whether such action is taken
     or brought with respect to a party to this Agreement) or (y) a Change in
     Tax Law, the party (which will be the Affected Party) will, or there is a
     substantial likelihood that it will, on the next succeeding Scheduled
     Payment Date (1) be required to pay to the other party an additional amount
     in respect of an Indemnifiable Tax under Section 2(d)(i)(4) (except in
     respect of interest under Section 2(e), 6(d)(ii) or 6(e)) or (2) receive a
     payment from which an amount is required to be deducted or withheld for or
     on account of a Tax (except in respect of interest under Section 2(e),
     6(d)(ii) or 6(e)) and no additional amount is required to be paid in
     respect of such Tax under Section 2(d)(i)(4) (other than by reason of
     Section 2(d)(i)(4)(A) or (B));

     (iii) TAX EVENT UPON MERGER. The party (the "Burdened Party") on the next
     succeeding Scheduled Payment Date will either (1) be required to pay an
     additional amount in respect of an Indemnifiable Tax under Section
     2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
     6(e)) or (2) receive a payment from which an amount has been deducted or
     withheld for or on account of any Indemnifiable Tax in respect of which the
     other party is not required to pay an additional amount (other than by
     reason of Section 2(d)(i)(4)(A) or (B)), in either case as a result of a
     party consolidating or amalgamating with, or merging with or into, or
     transferring all or substantially all its assets to, another entity (which
     will be the Affected Party) where such action does not constitute an event
     described in Section 5(a)(viii);

     (iv) CREDIT EVENT UPON MERGER. If "Credit Event Upon Merger" is specified
     in the Schedule as applying to the party, such party ("X"), any Credit
     Support Provider of X or any applicable Specified Entity of X consolidates
     or amalgamates with, or merges with or into, or transfers all or
     substantially all its assets to, another entity and such action does not
     constitute an event described in Section 5(a)(viii) but the
     creditworthiness of the resulting, surviving or transferee entity is
     materially weaker than that of X, such Credit Support Provider or such
     Specified Entity, as the case may be, immediately prior to such action
     (and, in such event, X or its successor or transferee, as appropriate, will
     be the Affected Party); or

     (v) ADDITIONAL TERMINATION EVENT.  If any "Additional Termination Event is
     specified in the Schedule or any Confirmation as applying, the occurrence
     of such event (and, in such event, the Affected Party or Affected Parties
     shall be as specified for such Additional Termination Event in the Schedule
     or such Confirmation).

(c) EVENT OF DEFAULT AND ILLEGALITY. If an event or circumstance which would
otherwise constitute or give rise to an Event of Default also constitutes an
Illegality, it will be treated as an Illegality and will not constitute an Event
of Default.

                                       7

6.   EARLY TERMINATION

(a)  RIGHT TO TERMINATE FOLLOWING EVENT OF DEFAULT. If at any time an Event of
Default with respect to a party (the "Defaulting Party") has occurred and is
then continuing, the other party (the "Non-defaulting Party") may, by not more
than 20 days notice to the Defaulting Party specifying the relevant Event of
Default, designate a day not earlier than the day such notice is effective as an
Early Termination Date in respect of all outstanding Transactions. If, however,
"Automatic Early Termination" is specified in the Schedule as applying to a
party, then an Early Termination Date in respect of all outstanding Transactions
will occur immediately upon the occurrence with respect to such party of an
Event of Default specified in Section 5(a)(vii)(1), (3), (5), (6) or, to the
extent analogous thereto, (8), and as of the time immediately preceding the
institution of the relevant proceeding or the presentation of the relevant
petition upon the occurrence with respect to such party of an Event of Default
specified in Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

(b) RIGHT TO TERMINATE FOLLOWING TERMINATION EVENT.

    (i) NOTICE. If a Termination Event occurs, an Affected Party will, promptly
    upon becoming aware of it, notify the other party, specifying the nature of
    that Termination Event and each Affected Transaction and will also give such
    other information about that Termination Event as the other party may
    reasonably require.

    (ii) TRANSFER TO AVOID TERMINATION EVENT.  If either an Illegality under
    Section 5(b)(i)(1) or a Tax Event occurs and there is only one Affected
    Party, or if a Tax Event Upon Merger occurs and the Burdened Party is the
    Affected Party, the Affected Party will, as a condition to its right to
    designate an Early Termination Date under Section 6(b)(iv), use all
    reasonable efforts (which will not require such party to incur a loss,
    excluding immaterial, incidental expenses) to transfer within 20 days after
    it gives notice under Section 6(b)(i) all its rights and obligations under
    this Agreement in respect of the Affected Transactions to another of its
    Offices or Affiliates so that such Termination Event ceases to exist.

    If the Affected Party is not able to make such a transfer it will give
    notice to the other party to that effect within such 20 day period,
    whereupon the other party may effect such a transfer within 30 days after
    the notice is given under Section 6(b)(i).

    Any such transfer by a party under this Section 6(b)(ii) will be subject to
    and conditional upon the prior written consent of the other party, which
    consent will not be withheld if such other party's policies in effect at
    such time would permit it to enter into transactions with the transferee on
    the terms proposed.

    (iii) TWO AFFECTED PARTIES. If an Illegality under Section 5(b)(i)(1) or a
    Tax Event occurs and there are two Affected Parties, each party will use all
    reasonable efforts to reach agreement within 30 days after notice thereof is
    given under Section 6(b)(i) on action to avoid that Termination Event.

    (iv) RIGHT TO TERMINATE. If:-

        (1) a transfer under Section 6(b)(ii) or an agreement under Section
        6(b)(iii), as the case may be, has not been effected with respect to all
        Affected Transactions within 30 days after an Affected Party gives
        notice under Section 6(b)(i); or

        (2) an Illegality under Section 5(b)(i)(2), a Credit Event Upon Merger
        or an Additional Termination Event occurs, or a Tax Event Upon Merger
        occurs and the Burdened Party is not the Affected Party,

    either party in the case of an Illegality, the Burdened Party in the case of
    a Tax Event Upon Merger, any Affected Party in the case of a Tax Event or an
    Additional Termination Event if there is more than one Affected Party, or
    the party which is not the Affected Party in the case of a Credit Event Upon
    Merger or an Additional Termination Event if there is only one Affected
    Party may, by not more than 20 days notice to the other party and provided
    that the relevant Termination Event is then

                                       8
<PAGE>
 
    continuing, designate a day not earlier than the day such notice is
    effective as an Early Termination Date in respect of all Affected
    Transactions.

(c) EFFECT OF DESIGNATION.

    (i) If notice designating an Early Termination Date is given under Section
    6(a) or (b), the Early Termination Date will occur on the date so
    designated, whether or not the relevant Event of Default or Termination
    Event is then continuing.

    (ii) Upon the occurrence or effective designation of an Early Termination
    Date, no further payments or deliveries under Section 2(a)(i) or 2(e) in
    respect of the Terminated Transactions will be required to be made, but
    without prejudice to the other provisions of this Agreement.  The amount, if
    any, payable in respect of an Early Termination Date shall be determined
    pursuant to Section 6(e).

(d) CALCULATIONS.

    (i) STATEMENT.  On or as soon as reasonably practicable following the
    occurrence of an Early Termination Date, each party will make the
    calculations on its part, if any, contemplated by Section 6(e) and will
    provide to the other party a statement (1) showing, in reasonable detail,
    such calculations (including all relevant quotations and specifying any
    amount payable under Section 6(e)) and (2) giving details of the relevant
    account to which any amount payable to it is to be paid.  In the absence of
    written confirmation from the source of a quotation obtained in determining
    a Market Quotation, the records of the party obtaining such quotation will
    be conclusive evidence of the existence and accuracy of such quotation.

    (ii) PAYMENT DATE.  An amount calculated as being due in respect of any
    Early Termination Date under Section 6(e) will be payable on the day that
    notice of the amount payable is effective (in the case of an Early
    Termination Date which is designated or occurs as a result of an Event of
    Default) and on the day which is two Local Business Days after the day on
    which notice of the amount payable is effective (in the case of an Early
    Termination Date which is designated as a result of a Termination Event).
    Such amount will be paid together with (to the extent permitted under
    applicable law) interest thereon (before as well as after judgment) in the
    Termination Currency, from (and including) the relevant Early Termination
    Date to (but excluding) the date such amount is paid, at the Applicable
    Rate.  Such interest will be calculated on the basis of daily compounding
    and the actual number of days elapsed.

(e)  PAYMENTS ON EARLY TERMINATION.  If an Early Termination Date occurs, the
     following provisions shall apply based on the parties' election in the
     Schedule of a payment measure, either "Market Quotation" or "Loss", and a
     payment method, either the "First Method" or the "Second Method".  If the
     parties fail to designate a payment measure or payment method in the
     Schedule, it will be deemed that "Market Quotation" or the "Second Method",
     as the case may be, shall apply.  The amount, if any, payable in respect of
     an Early Termination Date and determined pursuant to this Section will be
     subject to any Set-off.

     (i)  EVENTS OF DEFAULT.  If the Early Termination Date results from an
          Event of Default:-

          (1) First Method and Market Quotation. If the First Method and Market
          Quotation apply, the Defaulting Party will pay to the Non-defaulting
          Party the excess, if a positive number, of (A) the sum of the
          Settlement Amount (determined by the Non-defaulting Party) in respect
          of the Terminated Transactions and the Termination Currency Equivalent
          of the Unpaid Amounts owing to the Non-defaulting Party over (B) the
          Termination Currency Equivalent of the Unpaid Amounts owing to the
          Defaulting Party. 

          (2) First Method and Loss. If the First Method and Loss apply, the
          Defaulting Party will pay to the Non-defaulting Party, if a positive
          number, the Non-defaulting Party's Loss in respect of this Agreement.

          (3) Second Method and Market Quotation. If the Second Method and
          Market Quotation apply, an amount will be payable equal to (A) the sum
          of the Settlement Amount (determined by the

          Non-defaulting Party) in respect of the Terminated Transactions and
          the Termination Currency Equivalent of the Unpaid Amounts owing to the
          Non-defaulting Party less (B) the Termination Currency Equivalent of
          the Unpaid Amounts owing to the Defaulting Party. If that amount is a
          positive number, the Defaulting Party will pay it to the Non-
          defaulting Party; if it is a negative number, the Non-defaulting Party
          will pay the absolute value of that amount to the Defaulting Party.

          (4) Second Method and Loss. If the Second Method and Loss apply,an
          amount will be payable equal to the Non-defaulting Party's Loss in
          respect of this Agreement. If that amount is a positive number, the
          Defaulting Party will pay it to the Non-defaulting Party; if it is a
          negative number, the Non-defaulting Party will pay the absolute value
          of that amount to the Defaulting Party.

    (ii)  TERMINATION EVENTS.  If the Early Termination Date results from a
          Termination Event:-

          (1) One Affected Party. If there is one Affected Party, the amount
          payable will be determined in accordance with Section 6(e)(i)(3), if
          Market Quotation applies, or Section 6(e)(i)(4), if Loss applies,
          except that, in either case, references to the Defaulting Party and to
          the Non-defaulting Party will be deemed to be references to the
          Affected Party and the party which is not the Affected Party,
          respectively, and, if Loss applies and fewer than all the Transactions
          are being terminated, Loss shall be calculated in respect of all
          Terminated Transactions.

          (2) Two Affected Parties.  If there are two Affected Parties:-
              
              (A) if Market Quotation applies, each party will determine a
              Settlement Amount in respect of the Terminated Transactions, and
              an amount will be payable equal to (I) the sum of (a) one-half of
              the difference between the Settlement Amount of the party with the
              higher Settlement Amount ("X") and the Settlement Amount of the
              party with the lower Settlement Amount ("Y") and (b) the
              Termination Currency Equivalent of the Unpaid Amounts owing to X
              less (II) the Termination Currency Equivalent of the Unpaid
              Amounts owing to Y; and 

              (B) if Loss applies, each party will determine its Loss in respect
              of this Agreement (or, if fewer than all the Transactions are
              being terminated, in respect of all Terminated Transactions) and
              an amount will be payable equal to one-half of the difference
              between the Loss of the party with the higher Loss ("X") and the
              Loss of the party with the lower Loss ("Y").

          If the amount payable is a positive number, Y will pay it to X; if it
          is a negative number, X will pay the absolute value of that amount to
          Y.

    (iii) ADJUSTMENT FOR BANKRUPTCY. In circumstances where an Early Termination
    Date occurs because "Automatic Early Termination" applies in respect of a
    party, the amount determined under this Section 6(e) will be subject to such
    adjustments as are appropriate and permitted by law to reflect any payments
    or deliveries made by one party to the other under this Agreement (and
    retained by such other party) during the period from the relevant Early
    Termination Date to the date for payment determined under Section 6(d)(ii).

    (iv) PRE-ESTIMATE. The parties agree that if Market Quotation applies an
    amount recoverable under this Section 6(e) is a reasonable pre-estimate of
    loss and not a penalty. Such amount is payable for the loss of bargain and
    the loss of protection against future risks and except as otherwise provided
    in this Agreement neither party will be entitled to recover any additional
    damages as a consequence of such losses.

                                       10

7.   TRANSFER

Subject to Section 6(b)(ii), neither this Agreement nor any interest or
obligation in or under this Agreement may be transferred (whether by way of
security or otherwise) by either party without the prior written consent of the
other party, except that:-

(a)  a party may make such a transfer of this Agreement pursuant to a
     consolidation or amalgamation with, or merger with or into, or transfer of
     all or substantially all its assets to, another entity (but without
     prejudice to any other right or remedy under this Agreement); and

(b)  a party may make such a transfer of all or any part of its interest in any
     amount payable to it from a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be void.

8.   CONTRACTUAL CURRENCY

(a)  PAYMENT IN THE CONTRACTUAL CURRENCY.  Each payment under this Agreement
will be made in the relevant currency specified in this Agreement for that
payment (the "Contractual Currency"). To the extent permitted by applicable law,
any obligation to make payments under this Agreement in the Contractual Currency
will not be discharged or satisfied by any tender in any currency other than the
Contractual Currency, except to the extent such tender results in the actual
receipt by the party to which payment is owed, acting in a reasonable manner and
in good faith in converting the currency so tendered into the Contractual
Currency, of the full amount in the Contractual Currency of all amounts payable
in respect of this Agreement. If for any reason the amount in the Contractual
Currency so received falls short of the amount in the Contractual Currency
payable in respect of this Agreement, the party required to make the payment
will, to the extent permitted by applicable law, immediately pay such additional
amount in the Contractual Currency as may be necessary to compensate for the
shortfall. If for any reason the amount in the Contractual Currency so received
exceeds the amount in the Contractual Currency payable in respect of this
Agreement, the party receiving the payment will refund promptly the amount of
such excess.

(b) JUDGMENTS. To the extent permitted by applicable law, if any judgment or
order expressed in a currency other than the Contractual Currency is rendered
(i) for the payment of any amount owing in respect of this Agreement, (ii) for
the payment of any amount relating to any early termination in respect of this
Agreement or (iii) in respect of a judgment or order of another court for the
payment of any amount described in (i) or (ii) above, the party seeking
recovery, after recovery in full of the aggregate amount to which such party is
entitled pursuant to the judgment or order, will be entitled to receive
immediately from the other party the amount of any shortfall of the Contractual
Currency received by such party as a consequence of sums paid in such other
currency if such shortfall or such excess arises or results from any variation
between the rate of exchange at which the Contractual Currency is converted into
the currency of the judgment or order for the purposes of such judgment or order
and the rate of exchange at which such party is able, acting in a reasonable
manner and in good faith in converting the currency received into the
Contractual Currency, to purchase the Contractual Currency with the amount of
the currency of the judgment or order actually received by such party.  The term
"rate of exchange" includes, without limitation, any premiums and costs of
exchange payable in connection with the purchase of or conversion into the
Contractual Currency.

(c)   SEPARATE INDEMNITIES.  To the extent permitted by applicable law, these
indemnities constitute separate and independent obligations from the other
obligations in this Agreement, will be enforceable as separate and independent
causes of action, will apply notwithstanding any indulgence granted by the party
to which any payment is owed and will not be affected by judgment being obtained
or claim or proof being made for any other sums payable in respect of this
Agreement.

(d)  EVIDENCE OF LOSS.  For the purpose of this Section 8, it will be sufficient
for a party to demonstrate that it would have suffered a loss had an actual
exchange or purchase been made.

                                       11

Agreement will be effective unless in writing (including a writing evidenced by
a facsimile transmission) and executed by each of the parties or confirmed by an
exchange of telexes or electronic messages on an electronic messaging system.

(c)  SURVIVAL OF OBLIGATIONS. Without prejudice to Sections 2(a)(iii) and
6(c)(ii), the obligations of the parties under this Agreement will survive the

     facsimile transmission), each of which will be deemed an original.

     (ii) The parties intend that they are legally bound by the terms of each
     Transaction from the moment they agree to those terms (whether orally or
     otherwise). A Confirmation shall be entered into as soon as practicable and
     may be executed and delivered in counterparts (including by facsimile
     transmission) or be created by an exchange of telexes or by an exchange of
     electronic messages on an electronic messaging system, which in each case
     will be sufficient for all purposes to evidence a binding supplement to
     this Agreement. The parties will specify therein or through another
     effective means that any such counterpart, telex or electronic message
     constitutes a Confirmation.

(f)  NO WAIVER OF RIGHTS. A failure or delay in exercising any right, power or
privilege in respect of this Agreement will not be presumed to operate as a
waiver, and a single or partial exercise of any right, power or privilege will
not be presumed to preclude any subsequent or further exercise, of that right,
power or privilege or the exercise of any other right, power or privilege.

reference only and are not to affect the construction of or to be taken into
consideration in interpreting this Agreement.

10.  OFFICES; MULTIBRANCH PARTIES

(a)  If Section 10(a) is specified in the Schedule as applying, each party that
enters into a Transaction through an Office other than its head or home office
represents to the other party that, notwithstanding the place of booking office
or jurisdiction of incorporation or organisation of such party, the obligations
of such party are the same as if it had entered into the Transaction through its
head or home office.  This representation will be deemed to be repeated by such
party on each date on which a Transaction is entered into.

(b)  Neither party may change the Office through which it makes and receives
payments or deliveries for the purpose of a Transaction without the prior
written consent of the other party.

(c)  If a party is specified as a Multibranch Party in the Schedule, such
Multibranch Party may make and receive payments or deliveries under any
Transaction through any Office listed in the Schedule, and the Office through
which it makes and receives payments or deliveries with respect to a Transaction
will be specified in the relevant Confirmation.

11.  EXPENSES

A Defaulting Party will, on demand, indemnify and hold harmless the other party
for and against all reasonable out-of-pocket expenses, including legal fees and
Stamp Tax, incurred by such other party by reason of the enforcement and

(b)  JURISDICTION. With respect to any suit, action or proceedings relating to
this Agreement ("Proceedings"), each party irrevocably:-

     (i) submits to the jurisdiction of the English courts, if this Agreement is
     expressed to be governed by English law, or to the non-exclusive
     jurisdiction of the courts of the State of New York and the United States
     District Court located in the Borough of Manhattan in New York City, if
     this Agreement is expressed to be governed by the laws of the State of New
     York; and

     (ii) waives any objection which it may have at any time to the laying of
     venue of any Proceedings brought in any such court, waives any claim that
     such Proceedings have been brought in an inconvenient forum and further
     waives the right to object, with respect to such Proceedings, that such
     court does not have any jurisdiction over such party.

Nothing in this Agreement precludes either party from bringing Proceedings in
any other jurisdiction (outside, if this Agreement is expressed to be governed
by English law, the Contracting States, as defined in Section I(3) of the Civil
Jurisdiction and Judgments Act 1982 or any modification, extension or re-
enactment thereof for the time being in force) nor will the bringing of
Proceedings in any one or more jurisdictions preclude the bringing of
Proceedings in any other jurisdiction.

(c)  SERVICE OF PROCESS. Each party irrevocably appoints the Process Agent (if
any) specified opposite its name in the Schedule to receive, for it and on its
behalf, service of process in any Proceedings. If for any

                                       13
<PAGE>
 
reason any party's Process Agent is unable to act as such, such party will
promptly notify the other party and within 30 days appoint a substitute process
agent acceptable to the other party.  The parties irrevocably consent to
service of process given in the manner provided for notices in Section 12.

court, (iii) relief by way of injunction, order for specific performance or for
recovery of property, (iv) attachment of its assets (whether before or after
judgment) and (v) execution or enforcement of any judgment to which it or its
revenues or assets might otherwise be entitled in any Proceedings in the courts
of any jurisdiction and irrevocably agrees, to the extent permitted by
applicable law, that it will not claim any such immunity in any Proceedings.

"LOSS" means, with respect to this Agreement or one or more Terminated
Transactions, as the case may be, and a party, the Termination Currency
Equivalent of an amount that party reasonably determines in good faith to be its
total losses and costs (or gain, in which case expressed as a negative number)
in connection with this Agreement or that Terminated Transaction or group of
Terminated Transactions, as the case may be, including any loss of bargain, cost
of funding or, at the election of such party but without duplication, loss or
cost incurred as a result of its terminating, liquidating, obtaining or
reestablishing any hedge or related trading position (or any gain resulting from
any of them).  Loss includes losses and costs (or gains) in respect of any
payment or delivery required to have been made (assuming satisfaction of each
applicable condition precedent) on or before the relevant Early Termination Date
and not made, except, so as to avoid duplication, if Section 6(e)(i)(1) or (3)
or 6(e)(ii)(2)(A) applies.  Loss does not include a party's legal fees and out-

relevant rates or prices from one or more leading dealers in the relevant
markets.

"MARKET QUOTATION" means, with respect to one or more Terminated Transactions
and a party making the determination, an amount determined on the basis of
quotations from Reference Market-makers.  Each quotation will be for an amount,
if any, that would be paid to such party (expressed as a negative number) or by
such party (expressed as a positive number) in consideration of an agreement
between such party (taking into account any existing Credit Support Document
with respect to the obligations of such party) and the quoting Reference Market-
maker to enter into a transaction (the "Replacement Transaction") that would
have the effect of preserving for such party the economic equivalent of any
payment or delivery (whether the underlying obligation was, absolute or
contingent and assuming the satisfaction of each applicable condition precedent)
by the parties under Section 2(a)(i) in respect of such Terminated Transaction
or group of Terminated Transactions that would, but for the occurrence of the
relevant Early Termination Date, have

                                       15
<PAGE>
 
been required after that date.  For this purpose, Unpaid Amounts in respect of
the Terminated Transaction or group of Terminated Transactions are to be
excluded but, without limitation, any payment or delivery that would, but for
the relevant Early Termination Date, have been required (assuming satisfaction
of each applicable condition precedent) after that Early Termination Date is to
be included.  The Replacement Transaction would be subject to such documentation
as such party and the Reference Market-maker may, in good faith, agree.  The
party making the determination (or its agent) will request each Reference
Market-maker to provide its quotation to the extent reasonably practicable as
of the same day and time (without regard to different time zones) on or as soon
as reasonably practicable after the relevant Early Termination Date.  The day
and time as of which those quotations are to be obtained will be selected in
good faith by the party obliged to make a determination under Section 6(e), and,
if each party is so obliged, after consultation with the other.  If more than
three quotations are provided, the Market Quotation will be the arithmetic mean
of the quotations, without regard to the quotations having the highest and
lowest values.  If exactly three such quotations are provided, the Market
Quotation will be the quotation remaining after disregarding the highest and
lowest quotations.  For this purpose, if more than one quotation has the same
highest value or lowest value, then one of such quotations shall be disregarded.
If fewer than three quotations are provided, it will be deemed that the Market
Quotation in respect of such Terminated Transaction or group of Terminated
Transactions cannot be determined.

"NON-DEFAULT RATE" means a rate per annum equal to the cost (without proof or
evidence of any actual cost) to the Non-defaulting Party (as certified by it) if
it were to fund the relevant amount.

the lapse of time or both, would constitute an Event of Default.

selected by the party determining a Market Quotation in good faith (a) from
among dealers of the highest credit standing which satisfy all the criteria
that such party applies generally at the time in deciding whether to offer or to

dealers having an office in the same city.

"RELEVANT JURISDICTION" means, with respect to a party, the jurisdictions (a) in
which the party is incorporated, organised, managed and controlled or considered

Agreement and (d) in relation to any payment, from or through which such payment
is made.

under Section 6 is entitled or subject (whether arising under this Agreement,
another contract, applicable law or otherwise) that is exercised by, or imposed
on, such payer.

"SETTLEMENT AMOUNT" means, with respect to a party and any Early Termination
Date, the sum of:-

(a)  the Termination Currency Equivalent of the Market Quotations (whether
positive or negative) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation is determined; and 

(b)  such party's Loss (whether positive or negative and without reference to
any Unpaid Amounts) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation cannot be determined or would not (in
the reasonable belief of the party making the determination) produce a
commercially reasonable result. 

"SPECIFIED ENTITY" has the meaning specified in the Schedule.

before that Early Termination Date).

"TERMINATION CURRENCY" has the meaning specified in the Schedule.

"TERMINATION CURRENCY EQUIVALENT" means, in respect of any amount denominated in
the Termination Currency, such Termination Currency amount and, in respect of
any amount denominated in a currency other than the Termination Currency (the
"Other Currency"), the amount in the Termination Currency determined by the
party making the relevant determination as being required to purchase such
amount of such Other Currency as at the relevant Early Termination Date, or, if
the relevant Market Quotation or Loss (as the case may be), is determined as of
a later date, that later date, with the Termination Currency at the rate equal
to the spot exchange rate of the foreign exchange agent (selected as provided
below) for the purchase of such Other Currency with the Termination Currency at
or about 11:00 a.m. (in the city in which such foreign exchange agent is
located) on such date as would be customary for the determination of such a rate
for the purchase of such Other Currency for value on the relevant Early
Termination Date or that later date.  The foreign exchange agent will, if only
one party is obliged to make a determination under Section 6(e), be selected in
good faith by that party and otherwise will be agreed by the parties.

"TERMINATION EVENT" means an Illegality, a Tax Event or a Tax Event Upon Merger
or, if specified to be applicable, a Credit Event Upon Merger or an Additional
Termination Event.

"TERMINATION RATE" means a rate per annum equal to the arithmetic mean of the
cost (without proof or evidence of any actual cost) to each party (as certified
by such party) if it were to fund or of funding such amounts.

"UNPAID AMOUNTS" owing to any party means, with respect to an Early Termination
Date, the aggregate of (a) in respect of all Terminated Transactions, the
amounts that became payable (or that would have become payable but for Section
2(a)(iii)) to such party under Section 2(a)(i) on or prior to such Early
Termination Date and which remain unpaid as at such Early Termination Date and
(b) in respect of each Terminated Transaction, for each obligation under Section
2(a)(i) which was (or would have been but for Section 2(a)(iii)) required to be
settled by delivery to such party on or prior to such Early Termination Date and
which has not been so settled as at such Early Termination Date, an amount equal
to the fair market

                                       17
<PAGE>
 
value of that which was (or would have been) required to be delivered as of the
originally scheduled date for delivery, in each case together with (to the
extent permitted under applicable law) interest, in the currency of such
amounts, from (and including) the date such amounts or obligations were or would
have been required to have been paid or performed to (but excluding) such Early
Termination Date, at the Applicable Rate.  Such amounts of interest will be
calculated on the basis of daily compounding and the actual number of days
elapsed.  The fair market value of any obligation referred to in clause (b)
above shall be reasonably determined by the party obliged to make the
determination under Section 6(e) or, if each party is so obliged, it shall be
the average of the Termination Currency Equivalents of the fair market values
reasonably determined by both parties.

IN WITNESS WHEREOF the parties have executed this document on the respective
dates specified below with effect from the date specified on the first page of
this document.

     "Agreement") with such modifications as Party A and Party B will in good
     faith agree.  Upon execution by Party A and Party B of such Agreement, this
     Confirmation will supplement, form a part of and be subject to the
     Agreement.  All provisions contained or incorporated by reference in such
     Agreement upon its execution shall govern this Confirmation except as

     referring to the ISDA Form (each a "Confirmation") confirming Transactions
     (each a "Transaction") entered into between us (notwithstanding anything to
     the contrary in a Confirmation) shall supplement, form a part of, and be
     subject to an agreement in the form of the ISDA Form as if Party A and
     Party B had executed an agreement on the Trade Date of the first such
     Transaction between Party A and Party B in such form, with the Schedule
     thereto (i) specifying only that (a) the governing law is the law of the
     State of New York, without reference to choice of law doctrine, provided,

     of "Indemnifiable Tax" contained in (page 48 of) the ISDA

                         the Calculation Agent will make such adjustments,
                         effective as of the Merger Date, in respect of the
                         Settlement Price, Number of Shares (and Issuer), Number
                         of Shares to be Delivered and any other variable
                         relevant to the settlement or payment terms of this
                         Transaction, as the Calculation Agent determines
                         appropriate in its good faith commercially reasonable
                         judgment.

                         obligations in respect of future Settlement Dates and
                         subject to Netting above, the parties shall perform
                         their obligations as if the Early Settlement Date were
                         the Accelerated Settlement Date, except that Party B
                         shall not be obligated to pay the Advanced Settlement
                         Fee.

Nationalization or 
 Insolvency:             A Nationalization or an Insolvency will constitute an
                         Additional Termination Event with this Transaction as
                         the sole Affected Transaction and Party B as the sole
                         Affected Party.

MISCELLANEOUS:

Early Termination 
 Events:                 A default under the Securities Loan Agreement that
                         entitles Party A to terminate such agreement shall
                         constitute an Additional Termination Event with this
                         Transaction as the sole Affected Transaction and Party
                         B as the sole Affected Party.


Default Interest:        If, prior to the occurrence or effective designation of
                         an Early Termination Date in respect of this
                         Transaction, a party fails to perform any obligation
                         required to be settled by delivery, it will indemnify
                         the other party on demand for any costs, losses or
                         expenses (including the costs of borrowing Shares, if
                         applicable) resulting from such failure. A

                         certificate signed by the deliveree setting out such
                         costs, losses or expenses in reasonable detail shall be
                         conclusive evidence that they have been incurred.

Representation and 
 Agreement:              The party required to deliver Shares agrees that it
                         will convey and, on each date that it delivers Shares,
                         represents that it has conveyed, good title to the
                         Shares it is required to deliver, free and clear of any
                         lien, charge, claim or other encumbrance and on each
                         such date represents that any Shares it is required to
                         deliver do not constitute "restricted securities" and
                         are not subject to restrictions on transfer (including
                         so-called "control securities") under the Securities
                         Act (as defined below) or otherwise.

Method of Delivery:      Whenever delivery of funds or Shares is required
                         hereunder by or to Party B, such delivery shall be
                         effected through DMG. In addition, all notices, demands
                         and communications of any kind relating to this
                         Transaction between Party A and Party B shall be
                         transmitted exclusively through DMG.

           the meaning of Regulation U of the Board of Governors of the Federal
           Reserve System.

4.   MODIFICATIONS TO ISDA FORM:

(a)  The "CROSS DEFAULT" provisions of Section 5(a)(vi) will apply to both
     parties subject to amendment by adding at the end thereof the following
     words:

                "and in either case, the other party determines in good faith
        that it has reasonable grounds to conclude that the performance by the
        Defaulting Party of its financial obligations hereunder is endangered."

     With regard to Party A, "Threshold Amount" means 3% of Deutsche Bank AG's
     shareholders' equity (i.e., the sum of capital and disclosed reserves).

     With regard to Party B, "Threshold Amount" means USD5,000,000.

(b)  The "CREDIT EVENT UPON MERGER" provision in Section 5(b)(iv), which applies
     to both parties, is hereby amended to read as follows:

     "(iv)  CREDIT EVENT UPON MERGER. "Credit Event Upon Merger" means that a
     Designated Event (as defined below) occurs with respect to a party, any
     Credit Support Provider of such party or any applicable Specified Entity of
     such party (in each case, "X") and such Designated Event does not
     constitute a Merger Without Assumption under Section 5(a)(viii) hereof but
     that, in the reasonable opinion of the other party, the creditworthiness of
     X or, if applicable, the successor, surviving or transferee entity of X,
     after taking into account any applicable Credit Support Document, is
     materially weaker than X immediately prior to such action, (and, in such
     event, such party or its successor, surviving or transferee entity, as
     appropriate, will be the Affected Party). For purposes hereof, a Designated
     Event with respect to X means that, after the date of this Agreement:

     (1)        X consolidates or amalgamates with, or merges into, or transfers
     all or substantially all of its assets (or any substantial part of the
     assets comprising the business conducted by X as of the date of this
     Agreement) to, or receives all or substantially all the assets or
     obligations of, another entity;

     (2)        any person or entity acquires directly or indirectly the
     beneficial ownership of equity securities having the power to elect a
     majority of the board of directors of X or otherwise acquires directly or
     indirectly the power to control the policy-making decisions of X;

     (3)        X effects any substantial change in its capital structure by
     means of the issuance, incurrence or guarantee of debt or the issuance of
     preferred stock or other securities convertible into, or exchangeable for,
     debt or preferred stock; or

     (4)        X enters into any agreement providing for any of the foregoing."


(c)  SET OFF.  Section 6 of this Agreement is amended by the addition of the
following Section 6(f):

     "(f) Any amount (the "Early Termination Amount") payable to one party (the
     "Payee") by the other party (the "Payer") under Section 6(e), in
     circumstances where there is a Defaulting Party or one Affected Party in
     the case where a Termination Event under Section 5(b)(iv) has occurred,
     will, at the option of the party ("X") other than the Defaulting Party or
     the Affected Party (and without prior notice to the Defaulting Party or the
     Affected Party), be reduced by its set-off against any amount(s) (the
     "Other Agreement Amount") payable (whether at such time or in the future or
     upon the occurrence of a contingency) by the Payee to the Payer
     (irrespective of the currency, place of payment or booking office of the
     obligation) under any other agreement(s) between the Payee and the Payer or
     instrument(s) or undertaking(s) issued or 

                                       6
<PAGE>
 
     executed by one party to, or in favor of, the other party (and the Other
     Agreement Amount will be discharged promptly and in all respects to the
     extent it is so set-off). X will give notice to the other party of any set-
     off effected under this Section 6(f).

     For this purpose, either the Early Termination Amount or the Other
     Agreement Amount (or the relevant portion of such amounts) may be converted
     by X into the currency in which the other is denominated at the rate of
     exchange at which such party would be able, acting in a reasonable manner
     and in good faith, to purchase the relevant amount of such currency.

     If an obligation is unascertained, X may in good faith estimate that
     obligation and set-off in respect of the estimate, subject to the relevant
     party accounting to the other when the obligation is ascertained.

     Nothing in this Section 6(f) shall be effective to create a charge or other
     security interest. This Section 6(f) shall be without prejudice and in
     addition to any right of set-off, combination of accounts, lien or other
     rights to which any party is at any time otherwise entitled (whether by
     operation of law, contract or otherwise)."

     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 April 16, 1998 (as such may
be further amended or supplemented, the "Registration Statement"), in connection
with the registration under the Securities Act of 1933, as amended, of up to
3,795,000 shares (including an over-allotment option granted to the
Underwriters to purchase 495,000 shares) of your Common Stock, $.001 par value
per share (the "Shares"). Of the Shares, 1,463,870 shares (including all
shares subject to the above-referenced over-allotment option) are authorized but
heretofore unissued, and 2,331,130 shares are or will be issued and outstanding
and held by the selling stockholders referred to in the Registration Statement.
We understand that the Shares are to be sold to the Underwriters for resale to
the public as described in the Registration Statement. As your legal counsel, we
have examined the proceedings taken, and are familiar with the proceedings
proposed to be taken, by you in connection with the issuance and sale of the
Shares.

         It is our opinion that the Shares, when issued and sold in the manner
described 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 amendments thereto.

                                      Very truly yours,

                                      WILSON SONSINI GOODRICH & ROSATI

             CONFIDENTIAL MUTUAL RELEASE AND SETTLEMENT AGREEMENT

          Daniel I. Rubin ("Employee") and Artisan Components, Inc. ("Artisan
Components") have mutually agreed that Employee's employment with Artisan
Components will terminate effective April 15, 1998 ("Termination Effective
Date").  To assist in a reasonable transition in connection with Employee's
termination of employment, Employee and Artisan Components agree as follows:

          1.  Artisan Components has no policy obligating it to pay severance
benefits to terminated executive employees.  However, in return for Employee's
execution of and adherence to this Agreement, and in particular for the release
that forms a material part of this Agreement, Artisan Components shall provide
Employee with certain severance benefits to which he would not otherwise be
entitled.  Said severance benefits are set forth in the attached Exhibit A which
is incorporated herein by reference.  Artisan Components will make all
deductions from such compensation as required by law and Artisan Components'
policy and practice.

          2.  In further consideration of the mutual promises herein, Employee
on behalf of himself, his heirs and assignees hereby irrevocably and
unconditionally releases and forever discharges, individually and collectively,
Artisan Components, and its officers, directors, employees, shareholders,
representatives, subsidiaries, predecessors, successors, assigns, and all
persons acting by, through or in concert with them (hereinafter "Company"), of
and from any and all charges, claims, complaints, demands, liabilities, causes
of action, losses, costs or expenses of any kind whatsoever (including related
attorneys' fees and costs), known or unknown, suspected or unsuspected, that
Employee may now have or has ever had against Company by reason of any act,
omission, transaction, or event occurring up to the later of (i) the date of
signing this Agreement, or (ii) the Termination Effective Date.  This includes
without limitation, any wrongful or unlawful discharge claim, any claims
relating to any contracts of employment whether express or implied, any claims
related to compensation, including any stock or any other claims related to
Employee's employment with Artisan Components and the termination thereof. The
foregoing shall not discharge Artisan Components' obligations under this
Agreement.

          3.  In further consideration of the mutual promises herein, Artisan
Components on behalf of itself, and its officers, directors, employees,
representatives, subsidiaries, predecessors, successors, assigns, and all
persons acting by, through or in concert with them hereby irrevocably and
unconditionally releases and forever discharges, Employee, his spouse, heirs,
assigns, agents and representatives, of and from any and all charges, claims,
complaints, demands, liabilities, causes of action, losses, costs or expenses of
any kind whatsoever (including related attorneys' fees and costs), known or
unknown, suspected or unsuspected, that Artisan Components may now have or has
ever had against Employee by reason of any act, omission, transaction, or event
occurring up to the later of (i) the date of signing this Agreement, or (ii) the
Termination Effective Date. The foregoing shall not discharge Employee's
obligations under this Agreement.

          4.  Employee and Artisan Components each expressly waives all rights
and benefits afforded by Section 1542 of the California Civil Code and
acknowledges the significance and consequence of this waiver.  Section 1542
provides as follows:

          "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE,
WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE
DEBTOR."

          5.  Employee agrees that he will keep the fact and terms of this
Agreement and the negotiations leading to it completely confidential and that he
will not hereafter disclose or publish any information concerning such matters
to anyone other than his family, his attorney and his accountant. Employee may

                                      -1-
<PAGE>
 
make such disclosures as are finally compelled by law provided Employee gives
Artisan Components prompt notice of such legal process in order that Artisan
Components shall have the opportunity to object to the disclosure of such
information.

          6.  Employee shall not publish or disclose to any third party any
confidential or proprietary information concerning Artisan Components which was
acquired or learned during the course of Employee's employment with Artisan
Components.  By way of example and not limitation, such information includes
management organization, salary structures, financial results and conditions,
product quality, product pricing, business model, distribution strategy,
customer lists and preferences, marketing plans, product development, and other
business activities, strategies and plans, to the extent such matters have been
maintained as confidential by Artisan Components, or constitute proprietary
information under the law.  Confidential Information shall not include
information already known to third parties without an obligation of non-
disclosure and rightfully acquired by them.  The provisions of this section
shall not restrict Employee's obligation to disclose such information when
finally compelled by law provided Employee gives Artisan Components prompt
notice of such legal process in order that Artisan Components shall have the
opportunity to object to the disclosure of such information.

          7.  Any controversy or any claim of any kind arising out of or
relating to this Agreement, its breach, or Employee's termination of employment,
including but not limited to, any claim relating to its validity or
enforceability which is not settled by agreement between the parties, shall be
submitted to binding arbitration in accordance with the commercial arbitration
rules of the American Arbitration Association or any successor thereto.  A
neutral arbitrator shall be jointly chosen by the parties from a list of
arbitrators provided by the American Arbitration Association office closest to
Sunnyvale, California, and any hearings shall be held at such office.  The award
issued by the arbitrator shall be final and binding upon the parties, and
judgment on the award may be entered in any court having jurisdiction.  The fees
and costs of the arbitrator and administrative fees shall be borne equally by
the parties. The arbitrator shall have the power to award attorney's fees to the
prevailing party.  In consideration of each party's agreement to submit to
arbitration all disputes with regard to this Agreement, each party agrees that
the arbitration provisions hereof shall provide their exclusive remedy, and each
party expressly waives any right they may otherwise have to seek redress in any
other forum.  The parties further agree that the arbitrator acting hereunder
shall not be empowered to add to, subtract from or in any other manner modify,
alter or amend the terms of this Agreement.

          8.  Employee shall not solicit any employee of Artisan Components to
terminate their employment with Artisan Components prior to the date twelve (12)
months after the Termination Effective Date.

          9.  Employee agrees not to disparage Artisan Components, its products,
services and employees.  Artisan Components agrees not to disparage Employee.

          10. This Agreement shall be governed by the laws of California, and
shall inure to the benefit of Artisan Components and its successors and assigns.
In the event any provision of this Agreement is determined by an arbitrator or a
court or other tribunal to be unenforceable for any reason, the remaining
provisions hereof shall remain in full force and effect and the unenforceable
provision(s) shall be interpreted and rewritten to give effect to the parties'
economic intentions. This is the entire Agreement between the parties and
supersedes all previous negotiations, agreements and understandings.  No
promise, inducement or agreement not herein expressed has been made by either
party hereto.  No

                                      -2-
<PAGE>
 
modifications of this Agreement can be made except in writing signed by Employee
and the President of Artisan Components.

          11. Employee and Artisan Components each agrees not to issue a press
release relating to this Confidential Mutual Release and Settlement Agreement or
Employee's termination without the other party's prior consent.  Notwithstanding
the foregoing, Employee acknowledges that Artisan Components may be required
under certain securities laws or other applicable laws or regulations to publish
some or certain elements of this Agreement and/or the fact of Employee's
termination.

          12. Employee will be entitled to COBRA benefits as provided by law.

appropriate taxing authorities and promptly furnish Artisan Components with tax
receipts evidencing the payments of such amounts, and (ii) the sum payable by
Licensee upon which the deduction or withholding is based shall be increased to
the extent necessary to ensure that, after such deduction or withholding,
Artisan Components receives and retains, free from liability for such deduction
or withholding, a net amount equal to the amount Artisan Components would have
received and retained in the absence of such required deduction or withholding.

  7.8 With respect to Licensed Integrated Circuits and License Fees, royalties
and other amounts which are payable to Artisan Components under this Agreement

Components or its designee, subject to the confidentiality provisions set forth
in this Agreement, 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 License Fees, royalties and other
amounts disclosed by such examination.  If such an examination reveals an
underpayment of more than five percent (5%), then Licensee shall promptly
reimburse Artisan Components for the cost of such examination.

hereunder, shall be in U.S. Dollars. If any currency conversion shall be
