THE COMPANY

Artisan is a leading developer of high performance, low power and high
density embedded memory and other IP components for the design and manufacture
of complex ICs. The Company offers highly differentiated memory, standard cell
and I/O components that meet the acute needs of complex System-on-a-Chip ICs
for performance, power and density. The Company's products are optimized for
each customer's manufacturing process and are delivered ready for use with
industry standard and proprietary IC design tools. Artisan's objective is to
be the leading supplier of high performance IP components to the semiconductor
market by (i) focusing on key IP components for high volume System-on-a-Chip
ICs, (ii) targeting leading semiconductor manufacturers, (iii) generating
revenue through an innovative business model, (iv) proliferating its IP
components throughout customer ICs, (v) leveraging its product development
process and (vi) maintaining its technological leadership. The Company
licenses its products to semiconductor manufacturers and fabless semiconductor
companies for the design of ICs used in complex, high volume applications,
such as portable computing devices, cellular phones, consumer multimedia
products, automotive electronics, personal computers and workstations.

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

5
<PAGE>

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 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

6
<PAGE>

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
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.

<PAGE>

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 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

8
<PAGE>

Company that obligates it to license future generations of products or new
products, and there can be no assurance that any customer will license IP
components from the Company in the future. In addition, there can be no
assurance that any of the Company's customers will ship products incorporating
the Company's technology or that, if such shipments occur, they will generate
significant revenue. The loss of one or more of the Company's major customers,
reduced orders by one or more of such customers or the failure of a customer
to ship products containing the Company's IP components could materially
adversely affect the Company's business, operating results and financial
condition. See "Business--Customers."

The Company faces numerous risks in successfully obtaining orders from
customers on terms consistent with the Company's business model, including,
among others, the lengthy and 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

9
<PAGE>

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 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."

10
<PAGE>

DEPENDENCE ON KEY PERSONNEL. The Company's success depends in large part on
the continued contributions of its key management, engineering, sales and
marketing personnel, many of whom are highly skilled and would be difficult to
replace. None of the Company's senior management or key technical personnel is
bound by an employment contract. In addition, the Company does not currently
maintain key man life insurance covering its key personnel. The Company
believes that its success depends to a significant extent on the ability of
its management to operate effectively, both individually and as a group.
Certain of the Company's senior management have only recently joined the
Company and there can be no assurance they and other newly hired employees
will be assimilated into the Company successfully. The Company must also
attract and retain highly skilled managerial, engineering, sales and marketing
and finance personnel. Competition for such personnel is intense, and there
can be no assurance that the Company will be successful in attracting and
retaining such personnel. The loss of the services of any of the key
personnel, the inability to attract or retain qualified personnel in the
future or delays in hiring required personnel, particularly engineers, could
have a material adverse effect on the Company's business, operating results
and financial condition. See "Business--Employees" and "Management--Executive
Officers and Directors."

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

11
<PAGE>

future, that assertions by third parties will not result in costly litigation
or that the Company would prevail in any such litigation or be able to license
any valid and infringed patents from third parties on commercially reasonable
terms. Litigation, regardless of the outcome, could result in substantial cost
and diversion of resources of the Company. Any infringement claim or other
litigation against or by the Company could materially adversely affect the
Company's business, operating results and financial condition.

In certain instances, the Company has elected to rely on trade secret law
rather than patent law to protect its proprietary technology. However, trade
secrets are difficult to protect. The Company seeks to protect its proprietary
technology and processes, in part, by confidentiality agreements with its
employees and customers. There can be no assurance that these contracts will
not be breached, that the Company will have adequate remedies for any breach,
or that the Company's trade secrets will not otherwise become known or be
independently discovered by competitors. In addition, effective trade secret
protection may be unavailable or limited in certain foreign countries.

In addition, there can be no assurance that competitors of the Company, many
of which have substantial resources and have made substantial investments in
competing technologies, 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,

12
<PAGE>

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 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 (45.3% if the Underwriters' over-allotment option is exercised in
full). As a result, these stockholders, acting together, would effectively be
able to control substantially all matters requiring approval by the
stockholders, including the election of directors. Such concentration of
ownership may have the effect of delaying, deferring or preventing a change in
control of the Company. See "Principal 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

13
<PAGE>

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 executive officers or founders with
continuing involvement with the Company 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
executive officers and founders with continuing involvement with the Company)
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
13,273,338 shares of Common Stock outstanding as of the date of this
Prospectus, of which 6,638,338 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
177,215 shares will become eligible for sale upon expiration of lock-up
agreements on August 1, 1998, (iii) approximately 2,912,548 shares will become
eligible for sale on the later of 90 days from the date of this Prospectus or
August 1, 1998 and (iv) approximately 3,548,575 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 net proceeds have
not been allocated to any specific purpose.

14
<PAGE>

USE OF PROCEEDS

The net proceeds to the Company from the sale of the 956,190 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$16.9 million (approximately $25.9 million if the Underwriters' over-allotment
option is exercised in full) at an assumed public offering price of $19.25 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

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

The following discussion should be read in conjunction with the Financial
Statements and Notes thereto included elsewhere in this Prospectus. Certain
statements in this "Management's Discussion and Analysis of Financial
Condition and Results of Operations" are forward looking statements. The
forward looking statements contained herein are based on current expectations
and entail various risks and uncertainties that could cause actual results to
differ materially from those expressed in such forward looking statements. For
a more detailed discussion of these and other business risks, see "Risk
Factors."

OVERVIEW

Artisan is a leading developer of high performance, low power and high
density embedded memory and other IP components for the design and manufacture
of complex ICs. The Company licenses its products to semiconductor
manufacturers and fabless semiconductor companies for the design of ICs used
in complex, high volume applications, such as portable computing devices,
cellular phones, consumer multimedia products, automotive electronics,
personal computers and workstations.

Revenue consists of license fees 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

18
<PAGE>

companies that manufacture at the same facility. Given that Artisan provides
its products early in the customer's IC design process, there will be a
significant delay between the delivery of a product and the generation of
royalty revenue. There can be no assurance that the Company will receive any
royalty revenue or that, if it does, the amount will be significant. See "Risk
Factors--Dependence on New Business Model."

The Company has been dependent on a relatively small number of customers for
a substantial portion of its annual revenue, although the customers comprising
this group have changed from time to time. In fiscal 1995, SGS-THOMSON, NEC,
the DOD, Samsung and LSI Logic accounted for 20%, 17%, 17%, 11% and 10% of
revenue, respectively. In fiscal 1996, ATI, SGS-THOMSON, OKI and the DOD
accounted for 37%, 20%, 15% and 10% of revenue, respectively. In fiscal 1997,
SGS-THOMSON, Fujitsu, OKI and NEC accounted for 27%, 24%, 16% and 13% of
revenue, respectively. 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

19
<PAGE>

Company's products, any of which could have a material adverse effect on the
Company's business, operating results and financial condition. In addition,
the Company's contracts with customers may generally be canceled without
cause, and if a customer cancels or delays performance under any such
contracts, the Company's business, operating results and financial condition
could be materially adversely affected. The Company's costs and expenses will
be based in part on the Company's expectations of future revenue from license
fees. Accordingly, if the Company does not realize its expected revenue, its
business, operating results and financial condition could be materially
adversely affected. See "Risk Factors--Fluctuations in Operating Results."

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.

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

21
<PAGE>

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.

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.

22
<PAGE>

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 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.

23
<PAGE>

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.

</TABLE>

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.

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,

25
<PAGE>

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. 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

26
<PAGE>

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 and in the six month period ended March 31, 1998
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. The Company may be required to raise
additional funds through public or private financing, strategic relationships
or other arrangements. There can be no assurance that such funding, if needed,
will be available on terms attractive to the Company, or at all. Furthermore,
any additional equity financing may be dilutive to stockholders, and debt
financing, if available, may involve restrictive covenants. Strategic
arrangements, if necessary to raise additional funds, may require the Company
to relinquish its rights to certain of its technologies or products. The
failure of the Company to raise capital when needed could have a material
adverse effect on the Company's business, operating results and financial
condition. See "Risk Factors--Future Capital Needs; Uncertainty of Additional
Funding" and "Use of Proceeds."

BUSINESS

Artisan is a leading developer of high performance, low power and high
density embedded memory and other IP components for the design and manufacture
of complex ICs. The Company offers highly differentiated memory, standard cell
and I/O components that meet the acute needs of complex System-on-a-Chip ICs
for performance, power and density. Together, memory, standard cell and I/O
components constitute approximately 80% of the silicon area on a typical
System-on-a-Chip IC. The Company's products are optimized for each customer's
manufacturing process and are delivered ready for use with industry standard
and proprietary IC design tools. The Company licenses its products to
semiconductor manufacturers and fabless semiconductor companies for the design
of ICs used in complex, high volume applications, such as portable computing
devices, cellular phones, consumer multimedia products, automotive
electronics, personal computers and workstations.

INDUSTRY BACKGROUND

The development of the merchant IP component market has resulted from the
continuing trend toward horizontal specialization in the semiconductor
industry, a trend that has been driven by a growth in manufacturing capacity
and an increasing focus on core competencies. In the 1970s, semiconductor
companies were vertically integrated and responsible for all aspects of IC
production, including IC design, EDA tool design, IP component design and
IC manufacturing. In the 1980s, application specific integrated circuit
("ASIC") companies developed a new approach that allowed their customers to
perform the logic design of an IC while they performed the detailed physical
implementation of the design and manufactured the IC. In addition, standalone
EDA tool vendors achieved success by providing software design tools to
complement those developed by internal divisions of semiconductor companies.
The early 1990s saw the emergence of a number of fabless semiconductor
companies that chose to focus on specific design expertise, take advantage of
the availability of excess semiconductor manufacturing capacity and avoid the
capital expenditures necessary to build fabrication facilities. Throughout
this period, semiconductor manufacturers continued to focus on their core
competencies: semiconductor design and manufacturing processes. Today, with
the emergence of System-on-a-Chip ICs, semiconductor manufacturers are
beginning to outsource the design of particular IP components critical to the
successful development of System-on-a-Chip ICs. This trend favors the
emergence of a substantial merchant IP component market that is estimated by
industry sources to grow from approximately $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.

28
<PAGE>

[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
product for this manufacturing process.

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

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.

All directors are elected at the Annual Meeting of Stockholders and hold
office until the election and qualification of their successors at the next
Annual Meeting of Stockholders. Officers serve at the discretion of the Board
of Directors and, therefore, the term of office for each officer is
indefinite. There are no family relationships among any of the Company's
directors or executive officers.

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
shares to Daniel I. Rubin. See "--Stock Plans."
(3) Options were granted at an exercise price equal to the fair market value
of the Company's Common Stock on the date of grant, as determined by the
Board of Directors. The Company's Common Stock was not traded publicly at
the time of the foregoing grant to Mr. Lewis.
(4) Mr. Rubin resigned effective April 15, 1998. See "Certain Transactions."

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

45
<PAGE>

extent the option had vested as of six months after the date of death or
disability. In the event of a merger of the Company with or into another
corporation, all outstanding options may be 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

46
<PAGE>

the offering period. If the fair market value of the Common Stock on any
purchase date is lower than such fair market value on the start date of that
offering period, then all participants in that offering period will be
automatically withdrawn 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.

47
<PAGE>

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 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

48
<PAGE>

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 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 13,273,338 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 6,638,338 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 177,215 shares will become eligible for sale upon
expiration of lock-up agreements on August 1, 1998 (iii) approximately
2,912,548 shares will become eligible for sale 90 days after the date of this
Prospectus and (iv) approximately 3,548,575 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 executive officers or founders with continuing involvement with the
Company 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 executive officers and
founders with continuing involvement with the Company) 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 the later of 90 days from the date of
this Prospectus or August 1, 1998. 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

58
<PAGE>

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 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.

(1) Includes 891,488 shares being sold short by Deutsche Bank, which shares it
will borrow from Synopsys. See "Principal and Selling Stockholders--
Synopsys Shares" and the discussion below.

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
arrangements by which all officers, directors, optionholders and substantially
all stockholders of the Company have agreed not to sell or otherwise dispose
of Common Stock or convertible securities of the Company until August 1, 1998,
without the prior consent of Deutsche Morgan Grenfell Inc. In addition, in

60
<PAGE>

connection with this Offering, Selling Stockholders who are founders still
active with the Company or executive officers have agreed not to sell or
otherwise transfer any shares of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock for a period of 180 days
after the date of this Prospectus. In connection with this Offering, the
directors, all other Selling Stockholders and the executive officers who are
not Selling Stockholders have agreed not to sell or otherwise transfer any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock for a period of 90 days after the date of this
Prospectus. The Company has agreed in the Underwriting Agreement that it will
not, directly or indirectly, without the prior written consent of Deutsche
Morgan Grenfell Inc., contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, or otherwise transfer or dispose of any shares of Common
Stock or any securities convertible into or exchangeable for Common Stock, for
a period of 180 days after the effective date of this Offering, without the
consent of Deutsche Morgan Grenfell Inc., except with respect to the issuance
of shares of Common Stock issued pursuant to any employee benefit plans,
qualified stock option plans or other employee compensation plans which are
discussed herein.

The Underwriting Agreement provides that the Company and the Selling
Stockholders 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.

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. See "Principal and Selling Stockholders--Synopsys Shares."
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 all of the Synopsys Shares prior
to the closing date of this Offering so that Deutsche Bank can use the
borrowed shares to effect its short sale. In return for use of the borrowed
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

<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.

ARTISAN COMPONENTS, INC.

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

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

The rights, preferences and privileges of the Preferred Stockholders are as
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
amounts have been paid on the Preferred Stock, the remaining assets are
distributed to the holders of the Common Stock. If liquidation occurs prior to
March 20, 1999, the above preferences will also include an amount equal to a
25% rate of return on the original purchase price, compounded annually, from
the date of issuance.

Warrant

In connection with the issuance of the Series B Preferred Stock the Company
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
issuance of such shares. The variable number of shares purchasable upon any
exercise of the warrant (the "Additional Shares") is limited to such number of
shares of Series B Preferred Stock that, when combined with (x) the number of
shares of Series B Preferred Stock originally purchased by Synopsys, and (y)
any additional shares of Preferred Stock of the Company purchased by Synopsys
after the date of issuance of the warrant in
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
Stock Option Plan, as amended (the "1993 Plan") and the 1997 Director Option
Plan for issuance upon the exercise of nonstatutory and incentive stock
options to employees and consultants as of September 30, 1997. In November
1997, the Board of Directors also authorized and the stockholders approved,
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
expires in 2008. Options to purchase the Company's Common Stock may be granted
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
become exercisable as determined by the Board of Directors but generally at a
rate of 25% after the first year and 6.25% each quarter thereafter. Options
expire as determined by the Board of Directors but not more than ten years
after the date of grant.

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:

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

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).

NOTES TO FINANCIAL STATEMENTS--(CONCLUDED)

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
the adoption of a 1997 Employee Stock Purchase Plan and the adoption of a 1997
Director Option Plan. The Board of Directors also authorized, and the
stockholders approved, the reservation of an additional two million shares for
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.

On April 14, 1998, the Board of Directors 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,
including the sale of shares by certain Selling Stockholders.

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.
