                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information, including "Risk Factors" and the Financial Statements and Notes
thereto, appearing elsewhere in this Prospectus. This Prospectus contains
forward-looking statements that involve risks and uncertainties. The Company's
actual results may differ materially from the results discussed in such forward-
looking statements. Factors that may cause such a difference include, but are
not limited to, those discussed in "Risk Factors."
 
                                  THE COMPANY
 
   
     Aspec is a leading independent provider of commercially available design
implementation technology ("DIT") solutions for integrated circuit ("IC")
design. DIT consists of libraries of electrical circuits, often called cell
libraries, based on proprietary architectures, and a design methodology, which
together enable IC designers to implement the physical design of an IC in
silicon. Aspec's DIT supports many leading electronic design automation ("EDA")
tools and advanced process technologies at leading semiconductor foundries.
Aspec's DIT is designed to: (i) facilitate the rapid design of complex,
high-performance ICs in advanced process technologies, (ii) provide an
integrated design solution that increases productivity, (iii) preserve existing
EDA investments and (iv) allow customers to access multiple foundries for cost
control and alternate sourcing. Aspec's DIT provides designers with quick access
to accurate and complete cell libraries at a lower cost than developing an
equivalent internal solution. Aspec's DIT includes its AdverPro design
verification software which enables EDA tools to exchange data while maintaining
design intent, provides an accurate timing function across EDA tools and helps
to ensure compliance with proper design procedures.
    
 
     IC designers utilize various methods to meet their DIT requirements.
Application specific integrated circuit ("ASIC") vendors and IC companies
typically rely on internally developed DIT solutions while electronic systems
manufacturers such as PC companies rely on ASIC companies for their DIT.
However, it is becoming increasingly difficult for these methods to meet the
challenges of increased design complexity and increased time-to-market pressures
which confront IC designers. ASIC vendors and IC companies are also finding it
increasingly impracticable, costly and time consuming to develop and maintain
their own proprietary DIT. In addition, ASIC vendors and IC companies find it
increasingly difficult to allocate sufficient resources to DIT as more and more
resources are required for complex semiconductor design. Electronic systems
manufacturers are finding it desirable to control the intellectual property
content of their design in order to more rapidly adopt new process technologies
and effectively integrate the various steps in their design flows and,
consequently, to decrease the time-to-market for their products. Thus, these
companies are increasingly seeking a third-party solution to their DIT
requirements.
 
   
     The Company's strategy is to expand its position as a leading independent
provider of commercial DIT solutions for the semiconductor industry. As part of
this strategy, the Company intends to establish its DIT as an industry standard
by providing an open solution that supports many leading EDA tools and process
technologies at leading semiconductor foundries. Aspec is rapidly developing new
versions of its products to support the most advanced EDA tools and emerging
deep submicron process technologies. To broaden its customer base, the Company
is targeting companies that are currently relying on internal resources or ASIC
vendors for their DIT requirements. Another key element of Aspec's strategy is
to cultivate long-term relationships with its customers, leading semiconductor
foundries and EDA tool companies. Aspec believes that relationships with key
industry participants will enhance its ability to establish its DIT as an
industry standard.
    
 
   
     Aspec's suite of DIT products includes electrical circuit libraries, memory
compilers and AdverPro. The Company's products, which run on UNIX workstations
and Windows NT-based PCs, support over 30 industry standard EDA tools, including
those produced by Avant!, Cadence, Epic, Mentor, Synopsys and Viewlogic. The
Company sells its products through a direct sales force in North America, Japan
and Korea. In other parts of Asia and Europe, the Company markets its products
primarily through a limited number of independent representatives and
distributors. By supporting many of the world's leading semiconductor foundries
and IC manufacturers, the Company offers its customers a wide variety of
manufacturing sources. The Company's customers include Cadence, Compaq, IDT,
Samsung, Sanyo and Winbond.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the shares
of Common Stock offered hereby. This Prospectus contains forward-looking
statements that involve risks and uncertainties. The Company's actual results
may differ materially from the results discussed in such forward-looking
statements. Factors that may cause such a difference include, but are not
limited to, those discussed below.
 
     Fluctuations in Future Operating Results; Dependence Upon Timely Project
Completion.  The Company's operating results have fluctuated in the past and are
expected to fluctuate significantly from quarter to quarter and on an annual
basis in the future as a result of a number of factors including the size and
timing of customer orders; the Company's ability to achieve progress on
percentage of completion contracts; the length of the Company's sales cycle; the
timing of new product announcements and introductions by the Company and its
existing or future competitors; the Company's ability to develop, introduce and
market new products and product enhancements; market acceptance of the Company's
products; and general economic conditions. The Company's future operating
results are expected to fluctuate as a result of these and other factors, which
could have a material adverse effect on the Company's business, operating
results and financial condition. 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.
 
   
     A substantial majority of the Company's revenue is recognized on a
percentage of completion method based upon actual costs incurred. The completion
period typically ranges from three months to a year. Accordingly, revenue in any
quarter is dependent on progress towards completion of the project by the
Company. The Company has in the past experienced delays in the progress of
certain projects and there can be no assurance that such delays will not occur
with respect to future projects. Any delay or failure to achieve such progress
could result in damage to customer relationships and the Company's reputation,
diversion 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,
these contracts may generally be cancelled 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. A customer's license of the Company's products generally involves a
significant commitment of capital with the attendant delays frequently
associated with authorization procedures for substantial capital expenditures
within customer organizations. The Company plans to increase its operating
expenses in order to enhance certain of its existing products and to develop
additional cell libraries for emerging design processes. The Company also plans
to increase its sales and marketing expenses in an attempt to broaden its
customer base. These 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 revenues, its business, operating results
and financial condition could be materially adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
    
 
     Market Acceptance of Commercial DIT.  The Company has promoted the adoption
of commercial DIT which, to date, has been accepted by only a limited number of
customers. The vast majority of the Company's potential customers currently rely
on one or more DITs which were developed internally or by ASIC vendors. The
Company's future growth, if any, will depend upon the extent to which the
Company's current and potential customers choose to implement commercial DIT
solutions in general and the Company's commercial DIT solution in particular.
The failure of the Company's DIT to achieve market acceptance would result in a
material adverse effect on the Company's business, operating results and
financial condition. Substantially all of the Company's revenues in fiscal 1993,
1994 and 1995 were derived from vertically integrated semiconductor companies
that licensed the Company's DIT so that they could enter the merchant ASIC
market.
 
                                        5
<PAGE>   7
 
Commencing in fiscal 1996, the Company began to generate meaningful revenue from
licensing its products to fabless semiconductor companies and electronic systems
manufacturers. If the Company is not able to generate substantial revenue from
the licensing of its products to such companies, its business, operating results
and financial condition would be materially adversely affected.
 
   
     Customer Concentration.  The Company has been dependent on a relatively
small number of customers for a substantial portion of its annual revenue. In
fiscal 1994, Thesys Gesellschaft fur Mikroelektronik mbH ("Thesys"), Sanyo
Electric Co., Ltd. ("Sanyo"), Hyundai Electronics Industries Co., Ltd.
("Hyundai") and Samsung Electronics Co., Ltd. ("Samsung") accounted for 28.9%,
21.3%, 19.3% and 12.7% of revenue, respectively. In fiscal 1995, Samsung,
National Semiconductor Corporation ("NSC") and Yamaha Corporation ("Yamaha")
accounted for 18.2%, 17.3% and 15.1%, respectively, of the Company's revenue. In
fiscal 1996, Asahi Glass Co., Ltd. ("Asahi Glass") accounted for 10.5% of the
Company's revenue, and the Company's six largest customers accounted for 51.8%
of the Company's revenue. The Company anticipates that the majority of its
revenue will be derived from a relatively small number of customers through
fiscal 1997. None of the Company's customers has a written agreement with the
Company that obligates it to license additional products or to renew its
maintenance agreement, and there can be no assurance that any customer will
purchase additional software licenses or renew its maintenance agreement. 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
"Business -- Customers."
    
 
   
     Management of Growth.  The Company's business has grown rapidly with
revenue increasing from $6.6 million in fiscal 1995 to $15.3 million in fiscal
1996. The growth of the Company's business and expansion of its customer base
has placed and is expected to continue to place a significant strain on the
Company's management and operations. Certain key members of the Company's
management, including its Chief Financial Officer, joined the Company within the
past 12 months. The Company's future success will depend on its ability to
identify, attract, hire and retain skilled employees and to hire replacements
for employees that leave the Company. In this regard, the Company is actively
recruiting a Vice President, Sales, a Vice President, Engineering and several
additional engineering personnel. The Company's failure to continue to expand
its engineering organization in a timely manner could result in delays in the
progress on percentage of completion contracts and the Company's research and
development efforts, either of which could have a material adverse effect on the
Company's business, operating results and financial condition.
    
 
   
     The Company's expansion has also resulted in substantial growth in the
number of its employees and the burden placed upon its financial, accounting and
operating systems, resulting in increased responsibility for both existing and
new management personnel. For example, the number of employees at the Company
increased from 46 at the end of fiscal 1995 to 100 at February 28, 1997. The
Company is in the process of hiring additional accounting and financial
personnel and in establishing and upgrading its financial and accounting systems
and procedures to support its growth. There can be no assurance that the Company
will be able to identify, attract and retain experienced accounting and
financial personnel. The Company's future operating results will depend on the
ability of its management and other key employees to implement and improve its
systems for operations, financial control and information management, and to
recruit, train and manage its employee base. In particular, the Company's
ability to effectively manage and support any future growth will be
substantially dependent on its ability to improve its financial and management
controls, reporting and order entry systems and other procedures on a timely
basis. The Company also expects to increase its customer support operations to
the extent the installed base of the Company's products continues to grow. There
can be no assurance that the Company will be able to manage or continue to
manage its recent or any future growth successfully or to implement and maintain
adequate financial and management controls and procedures, and any inability to
do so would have a material adverse effect on the Company's business, operating
results and financial condition. The Company does not expect to sustain the
rates of revenue growth that it has
    
 
                                        6
<PAGE>   8
 
experienced in the past, and there can be no assurance that the Company will be
able to maintain or improve its operating results.
 
     Dependence Upon Continuous Product Development; Risk of Product
Delays.  The Company's customers operate 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 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 product introductions by EDA tool
companies, emerging process technologies and other technological developments in
the semiconductor industry. Any failure by the Company to anticipate or respond
adequately to changes in technology 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 be successful in its product
development efforts, 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. The Company has in the past experienced delays in the release dates
of certain of its products. If release dates of any new significant products or
product enhancements are delayed, the Company's business, operating results and
financial condition would be materially adversely affected. The Company could
also be exposed to litigation or claims from its customers in the event it does
not satisfy its delivery commitments. There can be no assurance that any such
claim will not have a material adverse effect on the Company's business,
operating results and financial condition. See "Business -- Research and
Development."
 
   
     Dependence Upon Semiconductor and Electronics Industries.  The Company is
dependent upon the semiconductor and electronics industries. Each of these
industries is characterized by rapid technological change, 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 new licenses of the Company's
products is influenced by the level of design efforts by its customers, and
factors negatively affecting any of 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 or electronics industry.
    
 
   
     Competition.  The market for commercial DIT products is new and emerging,
and the Company has few direct competitors. The Company principally competes
with the engineering departments of potential customers that develop and
maintain internally developed DIT. Certain of the Company's other potential
customers rely on proprietary DIT developed and maintained by ASIC vendors.
Although the Company believes that none of its competitors offer a complete DIT
solution, the Company's current competitors with respect to one or more aspects
of its DIT solution include Cascade Design Automation (a subsidiary of Oki
Semiconductor Ltd.) ("Cascade"), Compass Design Automation (a subsidiary of VLSI
Technology, Inc.) ("Compass"), Silicon Architects (a subsidiary of Synopsys,
Inc.) ("Si-Arc") and Artisan Components, Inc ("Artisan"). In addition, certain
semiconductor foundries currently offer or may in the future offer one or more
elements of a DIT solution. The Company does not offer EDA tools, and its
products are designed to be compatible with leading EDA tools. The Company
expects that the market for its products will become increasingly competitive in
the future. Among the Company's potential competitors are a number of large
vertically integrated semiconductor companies and numerous EDA software
companies that may develop products that compete with those of the Company.
Increased competition could eventually result in price reductions or reduced
operating margins which could
    
 
                                        7
<PAGE>   9
 
materially adversely affect the Company's business, operating results and
financial condition. Many of the Company's potential competitors have
significantly greater financial, technical, marketing and other resources than
the Company. As a result, they may be able to respond more quickly to new or
emerging technologies and to changes in customer requirements, or to devote
greater resources to the development, promotion and sale of their products than
can the Company. There can be no assurance that the Company will be able to
compete successfully against current or future competitors or that competitive
pressures will not materially adversely affect the Company's business, operating
results and financial condition. See "Business -- Competition."
 
   
     Risks Associated With International Operations.  A significant portion of
the Company's revenue is derived from customers outside the United States, and
the Company anticipates that international revenue will continue to be
significant in the future. Specifically, revenue from customers outside the
United States accounted for 83.7%, 54.2% and 66.2% of revenue in fiscal 1994,
1995 and 1996, respectively. The Company intends to continue to expand its sales
and marketing activities in Asia and Europe. The Company's 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
distributors and customers, difficulty in managing distributors or sales
representatives, 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 licensing and services or that
the foregoing factors will not have a material adverse effect on the Company's
business, operating results and financial condition. Although the Company prices
its products and services in United States dollars, currency exchange
fluctuations in countries in which the Company licenses its products could have
a material adverse effect on the Company's business, operating results and
financial condition by resulting in pricing that is not competitive with
products priced in local currencies. The Company does not currently hedge
against foreign currency fluctuations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Business -- Sales and
Marketing."
    
 
     Limited Protection of Proprietary Rights.  The Company's success is
dependent on its ability to protect its proprietary technology. The Company
relies upon a combination of copyright, patent, trade secret and trademark laws
to protect its proprietary technology. The Company enters into confidentiality
agreements with its employees, distributors and customers and limits access to
and distribution of the source code to its software and other proprietary
information. There can be no assurance that the steps taken by the Company in
this regard will be adequate to prevent misappropriation of its technology or
that the Company's competitors will not independently develop technologies that
are substantially equivalent or superior to the Company's technology. Any such
misappropriation of the Company's technology or development of competitive
technologies could have a material adverse effect on the Company's business,
operating results and financial condition. Despite the Company's efforts to
protect its proprietary rights, there can be no assurance that the Company will
be able to protect its proprietary rights against unauthorized third party
copying or use. Attempts may be made to copy or reverse engineer aspects of the
Company's products or to obtain and use information that the Company regards as
proprietary. Policing the unauthorized use of the Company's products is
difficult and the Company could incur substantial costs in protecting and
enforcing its intellectual property rights. Litigation may be necessary in the
future to enforce the Company's intellectual property rights, to protect the
Company's trade secrets or to determine the validity and scope of the
proprietary rights of others. Such litigation could result in substantial costs
and diversion of resources and could have a material adverse effect on the
Company's business, operating results and financial condition.
 
     As of February 28, 1997, the Company held three U.S. patents which expire
from 2012 to 2013 and had six U.S. patent applications pending. The Company also
has 13 patent applications pending
 
                                        8
<PAGE>   10
 
   
in various foreign jurisdictions. The Company expects to continue to file patent
applications where appropriate to protect its proprietary technologies; however,
the Company believes that its continued success depends primarily on factors
such as the technological skills and innovation of its personnel rather than on
its patents. The Company has registered the trademarks Aspec Technology and
Mastergen and has four trademark applications pending in the United States. The
process of seeking patent and trademark protection can be expensive and time
consuming. There can be no assurance that patents or trademarks will issue from
pending or future applications or that, if issued, such patents or trademarks
will not be challenged, invalidated or circumvented, or that rights granted
thereunder will provide meaningful protection or other commercial advantage to
the Company. Moreover, there can be no assurance that any patent or trademark
rights will be upheld in the future or that the Company will be able to preserve
any of its other intellectual property rights. In addition, the laws of certain
countries in which the Company's products are distributed do not protect the
Company's products and intellectual property rights to the same extent as the
laws of the United States. Accordingly, effective trademark, copyright and
patent protection may be unavailable in certain foreign countries.
    
 
     As is common in the software industry, the Company may from time to time
receive notices from third parties claiming infringement by the Company's
products of third-party proprietary rights. While the Company is not currently
subject to any such claim, the Company believes that its products could
increasingly be subject to such claims as the market for its products grows and
as more competitors enter the market. Any such claim, with or without merit,
could result in significant litigation costs and require the Company to enter
into royalty and licensing agreements, which could have a material adverse
effect on the Company's business, operating results and financial condition.
Such royalty and licensing agreements, if required, may not be available on
terms acceptable by the Company or at all. See "Business -- Proprietary Rights."
 
   
     Potential for Software Defects.  Complex software products such as those
offered by the Company may contain undetected errors or defects commonly
referred to as "bugs." There can be no assurance that, despite significant
testing by the Company and by current and potential customers, errors will not
be found in products or enhancements to existing products after commencement of
commercial shipments. The Company does not presently maintain insurance with
respect to potential damages due to errors or defects in its products. Although
the Company has not experienced material adverse effects resulting from any such
errors or defects to date, there can be no assurance that errors or defects will
not be discovered in the future, potentially causing delays in product
introduction and shipments or requiring design modifications that could
materially adversely affect the Company's business, operating results and
financial condition.
    
 
   
     Dependence on Key Personnel.  The Company's business depends in significant
part on the continued service of the Company's executive officers and other
senior management and key employees, including certain technical, managerial and
marketing personnel. The loss of the services of any of these individuals or
groups of individuals could have a material adverse effect on the Company's
business, operating results and financial condition. None of the Company's
executive officers has an employment agreement with the Company. The Company
believes that its future business results will also depend in significant part
upon its ability to identify, attract, motivate and retain additional highly
skilled technical, managerial and marketing personnel. Competition for such
personnel in the computer software industry is intense. The Company is currently
engaged in a search for a Vice President, Sales, a Vice President, Engineering
and several additional engineering personnel. There can be no assurance the
Company will be successful in identifying, attracting and retaining such
personnel, and the failure to do so could have a material adverse effect on the
Company's business, operating results and financial condition.
    
 
     No Prior Market for the Shares; Expected Volatility of Share Price.  Prior
to the offering, there has been no public market for the Company's Common Stock
and there can be no assurance that an active public market will develop upon
completion of the offering or, if it does develop, that such market will be
sustained. The initial public offering price of the Company's Common Stock will
be
 
                                        9
<PAGE>   11
 
determined by negotiation between the Company and the Representatives of the
Underwriters. The market price of the shares of Common Stock is likely to be
highly volatile and may be significantly affected by factors such as actual or
anticipated fluctuations in the Company's operating results, the Company's
failure to meet or exceed published earnings estimates, changes in earnings
estimates or recommendations by securities analysts, announcements of
technological innovations, new products or new contracts by the Company or its
existing or potential competitors, developments with respect to patents,
copyrights or proprietary rights, conditions and trends in the EDA,
semiconductor or electronics industries, adoption of new accounting standards
affecting the software industry, general market conditions and other factors. In
addition, the stock market has from time to time experienced significant price
and volume fluctuations that have particularly affected the market prices for
the common stocks of technology companies which have often been unrelated to the
operating performance of such companies. These broad market fluctuations may
materially 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
securities, securities class action litigation has often been instituted against
such company. There can be no assurance that such litigation will not occur in
the future with respect to the Company. Such litigation could result in
substantial costs and a diversion of management's attention and resources, which
could have a material adverse effect upon the Company's business, operating
results and financial condition. See "Underwriting."
 
   
     Control by Officers, Directors and Affiliated Entities.  Upon completion of
the offering, the Company's executive officers, directors and venture capital
funds affiliated with such directors will beneficially own in the aggregate
approximately 60.8% of the issued and outstanding shares of Common Stock. Such
stockholders will have sufficient voting power to control the outcome of all
matters (including the election of directors and any merger, consolidation or
sale of all or substantially all of the Company's assets) submitted to the
stockholders for approval and may be deemed to have effective control over the
affairs and management of the Company. This controlling interest in the Company
may also have the effect of making certain transactions more difficult or
impossible, absent the support of such stockholders. Such transactions could
include a proxy contest, mergers involving the Company, tender offers and open
market purchase programs involving Common Stock that could give stockholders of
the Company the opportunity to realize a premium over the then prevailing market
price for their shares of Common Stock. See "Principal Stockholders."
    
 
   
     Benefits of the Offering to Current Stockholders.  Immediately after the
closing of this offering, based upon shares outstanding as of February 28, 1997,
the existing stockholders of the Company will hold 22,720,234 shares of Common
Stock, or approximately 85% of the total number of shares of Common Stock then
outstanding. The existing stockholders of the Company paid an aggregate of
approximately $10,460,000 to the Company for their shares of Common Stock.
Assuming an initial public offering price of $9.00 per share, the value of the
shares held by such existing stockholders would be approximately $204,482,000.
This offering will create a public market for the resale of shares held by these
existing stockholders. The existing holders of Common Stock will benefit from
the redemption of the Series A Redeemable Preferred Stock due to the termination
of the senior rights, preferences and privileges attributable to the Series A
Redeemable Preferred Stock. In addition, the holders of the Company's Series A
Redeemable Preferred Stock will benefit by having their shares of stock redeemed
using a portion of the proceeds of the offering.
    
 
     Effect of Anti-takeover Provisions.  The Company's Board of Directors has
the authority to issue up to 5,000,000 shares of Preferred Stock and to
determine the price, rights, preferences and privileges of such shares without
any further vote or action by the Company's 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 shares of Preferred Stock that may be issued in
the future. While the Company has no present intention to issue shares of
Preferred Stock, such issuance, while providing desirable flexibility in
connection with possible acquisitions and other corporate purposes, could have
the effect of making it more difficult for a third party to acquire a majority
of the outstanding voting stock of the Company. In addition, such Preferred
Stock may have other rights, including
 
                                       10
<PAGE>   12
 
economic rights senior to the Common Stock, and, as a result, the issuance
thereof could have a material adverse effect on the market value of the Common
Stock.
 
   
     Shares Eligible for Future Sale.  Sales of a substantial number of shares
of Common Stock in the public market following this offering could materially
adversely affect the market price for the Company's Common Stock. In addition to
the 4,000,000 shares of Common Stock offered hereby, as of the date of this
Prospectus (the "Effective Date") there will be 22,720,234 shares of Common
Stock outstanding (assuming no exercise of options after February 28, 1997), all
of which are "restricted" shares (the "Restricted Shares") under the Securities
Act of 1933, as amended (the "Securities Act"). Approximately 1,087,000
Restricted Shares will become eligible for sale 90 days after the Effective Date
pursuant to Rule 701 under the Securities Act. However, approximately 213,000 of
these shares will be subject to a right of repurchase in favor of the Company.
Approximately 17,272,000 Restricted Shares will become eligible for sale 180
days after the Effective Date upon expiration of certain lockup agreements with
the Company or the Underwriters and pursuant to Rules 144 and 701 under the
Securities Act, subject in certain cases to certain volume and other resale
restrictions under Rule 144. However, approximately 642,000 of these shares will
be subject to a right of repurchase in favor of the Company. The remaining
approximately 4,361,000 shares held by existing stockholders will become
eligible for sale from time to time in the future under Rule 144. Additionally,
an aggregate of approximately 69,250 shares issuable upon the exercise of stock
options will become eligible for sale in the public market 180 days after the
Effective Date upon expiration of lockup agreements with the Company or the
Underwriters and pursuant to a Registration Statement on Form S-8 which the
Company intends to file with the Securities and Exchange Commission
approximately 90 days after the Effective Date. In addition, holders of
approximately 4,779,000 shares of Common Stock have rights under certain
circumstances to require the Company to register their shares for future sale.
See "Shares Eligible for Future Sale."
    
 
     As described above, the number of shares of Common Stock available for sale
in the public market is limited by restrictions under the Securities Act and
lockup agreements under which the holders of such shares have agreed not to sell
or otherwise dispose of any of their shares for a period of 180 days after the
date of this Prospectus without the prior written consent of Alex. Brown & Sons
Incorporated. However, Alex. Brown & Sons Incorporated, may, in its sole
discretion and at any time without notice, release all or any portion of the
securities subject to lockup agreements. Alex. Brown & Sons Incorporated
currently has no plans to release any portion of the securities subject to
lockup agreements. When determining whether or not to release shares from the
lockup agreements, Alex. Brown & Sons Incorporated will consider, among other
factors, the stockholder's reasons for requesting the release, the number of
shares for which the release is being requested and market conditions at the
time.
 
   
     Dilution.  The initial public offering price is substantially higher than
the book value per share of the Common Stock. Investors purchasing shares of
Common Stock in the offering will incur immediate and substantial dilution of
$8.19 in net tangible book value per share of Common Stock (based upon an
assumed initial public offering price of $9.00 per share and after deducting
estimated underwriting discounts and commissions and offering expenses) from the
initial public offering price and will incur additional dilution upon the
exercise of outstanding stock options. See "Dilution."

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 4,000,000 shares of
Common Stock offered by the Company hereby at an assumed initial public offering
price of $9.00 per share, after deducting underwriting discounts and commissions
and estimated offering expenses, are estimated to be $32.6 million ($37.6
million if the Underwriters' over-allotment option is exercised in full). The
Company will use approximately $18.5 million of the proceeds of the offering to
redeem all outstanding shares of the Company's Series A Redeemable Preferred
Stock. The Company intends to use the remaining net proceeds of the offering for
working capital and general corporate purposes. A portion of the net proceeds
may also be used for investments in or acquisitions of complementary businesses,
products or technologies, although no such transactions are currently under
negotiation. Pending such uses, the Company expects to invest the net proceeds
in interest-bearing securities.
    
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid cash dividends on its Common Stock.
The Company currently intends to retain any earnings for use in its business and
does not anticipate paying any cash dividends on its Common Stock in the
foreseeable future.

                                    DILUTION
 
   
     The pro forma net tangible book value of the Company as of February 28,
1997 was a deficit of approximately $10.8 million, or $(0.48) per share of
Common Stock. "Pro forma net tangible book value" per share represents the
amount of total assets of the Company less total liabilities and the liquidation
value of the Series A Redeemable Preferred Stock, divided by the number of
shares of Common Stock outstanding. After giving effect to the sale by the
Company of 4,000,000 shares of Common Stock offered hereby (after deducting the
underwriting discounts and commissions and estimated offering expenses) at an
assumed initial public offering price of $9.00 per share, the pro forma net
tangible book value of the Company as of February 28, 1997 would have been $21.8
million, or $0.81 per share. This represents an immediate increase in net
tangible book value of $1.29 per share to existing stockholders and an immediate
dilution of $8.19 per share to new investors. The following table illustrates
this per share dilution:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     This Management's Discussion and Analysis of Financial Condition and
Results of Operations and other parts of this Prospectus contain forward-looking
statements that involve risks and uncertainties. The Company's actual results
may differ materially from the results discussed in such forward-looking
statements. Factors that may cause such a difference include, but are not
limited to, those discussed in "Risk Factors."
 
OVERVIEW
 
     Aspec was founded in December 1991 to develop, market and support a
commercial DIT. Through fiscal 1992, the Company was principally engaged in the
development of its first products and the establishment of customer
relationships. The Company recognized its initial revenue in fiscal 1993 as DIT
products were completed for customers designing gate array-based ASICs. In
fiscal 1993, 1994 and 1995, a substantial portion of the Company's revenue was
derived from the license of DIT products to vertically integrated semiconductor
manufacturers that were seeking to enter the merchant ASIC market. During these
years, the Company also expanded its development efforts. By fiscal 1996, the
Company had enhanced its DIT products for gate array-based ICs and had developed
DIT products for standard cell-based ICs supporting a number of foundry
processes. These developments allowed the Company to expand its customer base to
include other integrated semiconductor companies, fabless semiconductor
companies, electronics systems manufacturers and distributors that sell to such
entities.
 
     Revenue consists primarily of license fees for the Company's DIT products
which are adapted for the specific process technology used by the customer. To a
lesser extent, the Company realizes revenue from service and maintenance fees.
Typically a customer licenses a bundle of products which is accompanied by
design methodology documentation and training. The license of the Company's
products typically involves a lengthy sales cycle of up to 12 months because the
license generally involves a significant commitment of capital by the customer
and because Aspec's DIT is either replacing a customer's proprietary DIT or
introducing an entirely new DIT. These DIT products are licensed to customers on
a per design basis, a per site basis or an enterprise basis. The price for a
typical bundle of products ranges from approximately $50,000 on a per design
basis to over $2.0 million on an enterprise basis.
 
     Engineering efforts devoted to developing products for which revenue is
recognized on a percentage of completion basis are recognized as cost of
revenue. Engineering efforts devoted to developing the Company's core technology
and products not requiring adaptation are recognized as research and development
expense. As a result of its engineering efforts, the Company has developed a
substantial base of technology which the Company is able to reuse in other DIT
product offerings. The Company expects to continue to devote significant
resources to its various engineering efforts.
 
   
     A significant portion of the Company's revenue is derived from customers
outside the United States, and the Company anticipates that international
revenue will continue to be significant in the future. Specifically, revenue
from customers outside the United States accounted for 83.7%, 54.2% and 66.2% of
revenue in fiscal 1994, 1995 and 1996, respectively. The Company's international
operations are subject to risks inherent in the conduct of international
business, including unexpected changes in regulatory requirements, exchange
rates, export license requirements, tariffs and other barriers, political and
economic instability, limited intellectual property protection, difficulties in
collecting payments due from distributors or customers, difficulties in managing
distributors or representatives, and potentially adverse tax consequences.
Although the Company prices its products and services in United States dollars,
currency exchange fluctuations in countries in which the Company licenses its
products could have a material adverse effect on the Company's business,
operating results or financial condition by resulting in pricing that is not
competitive with products
    
 
                                       16

priced in local currencies. The Company does not currently hedge against foreign
currency fluctuations. To date, currency exchange fluctuations have not had a
material impact on the Company's financial results. See "Risk Factors -- Risks
Associated With International Operations."
    
 
   
     In May and June 1996, the Company issued an aggregate of 130,378 shares of
its Series A Redeemable Preferred Stock. The aggregate liquidation and
redemption value of the Series A Redeemable Preferred Stock is approximately
$18.5 million. The Company is accreting the difference between the book value of
the Series A Redeemable Preferred Stock and its redemption value over the period
from the issuance date through the mandatory redemption dates resulting in
accretion of approximately $0.8 million per year. In addition, in connection
with the redemption of all outstanding shares of such Series A Redeemable
Preferred Stock from the proceeds of the offering, the difference between the
book value and the redemption value of approximately $4.9 million will be
recorded as accretion for Preferred Stock when determining income attributable
to common stockholders and earnings per share. This $4.9 million of accretion
will be recorded in the third quarter of fiscal 1997 when the offering is
completed. See Note 6 of Notes to Financial Statements.

</TABLE>
 
COMPARISON OF FISCAL 1994, 1995 AND 1996
 
   
     Revenue.  Revenue increased 42.5% from $4.7 million in fiscal 1994 to $6.6
million in fiscal 1995 as the Company expanded sales of gate array-based DIT
products and initiated sales of standard cell-based DIT products to new
customers. Revenue increased 129.9% from $6.6 million in fiscal 1995 to $15.3
million in fiscal 1996 as the Company continued to expand its sales of standard
cell-based and gate array DIT products to a broader customer base.
    
 
   
     International revenue accounted for 83.7%, 54.2% and 66.2% of revenue in
fiscal 1994, 1995 and 1996, respectively. In fiscal 1994, Thesys, Sanyo, Hyundai
and Samsung accounted for 28.9%, 21.3%, 19.3% and 12.7% of revenue,
respectively. In fiscal 1995, Samsung, NSC and Yamaha accounted for 18.2%, 17.3%
and 15.1% of revenue, respectively. In fiscal 1996, Asahi Glass accounted for
10.5% of revenue, and the Company's six largest customers accounted for 51.8% of
    
 
                                       17

revenue. The Company anticipates that the majority of its revenue will be
derived from a relatively small number of customers through fiscal 1997.
    
 
   
     Cost of revenue.  Cost of revenue primarily represents the costs of
personnel and other operating expenses incurred in the development and
production of DIT products to customer specifications. Cost of revenue increased
from $1.6 million in fiscal 1994 to $2.3 million in fiscal 1995 and $4.7 million
in fiscal 1996. Cost of revenue has fluctuated from 33.3% of revenue in fiscal
1994 to 34.7% of revenue in 1995 and 30.8% of revenue in fiscal 1996. The
reduction in cost of revenue as a percentage of revenue in fiscal 1996 reflects
increased revenue in the second half of the year from products that did not
require significant adaptation.
    
 
   
     Research and development.  Research and development expense represents the
cost of engineering personnel and other operating expenses incurred in the
development and enhancement of the Company's core technology and products not
requiring significant adaptation. Research and development expense increased
from $289,000 in fiscal 1994 to $445,000 in fiscal 1995 and $921,000 in fiscal
1996. These increases primarily reflect increases in engineering personnel and
related expenses. As a percentage of revenue, research and development expense
fluctuated from 6.2% in fiscal 1994 to 6.7% in fiscal 1995 and 6.0% in fiscal
1996. The Company expects research and development expense to increase in
absolute dollars in future periods as the Company expands its engineering
efforts. The expected increase in the Company's research and development expense
could have a material adverse effect on the Company's business, operating
results and financial condition if the Company's revenue does not also increase.
    
 
   
     Sales and marketing.  Sales and marketing expense consists of salaries,
commissions paid to internal sales and marketing personnel and sales
representative promotional costs and related operating expenses. Sales and
marketing expense increased from $624,000 in fiscal 1994 to $1.4 million in
fiscal 1995 and $3.5 million in fiscal 1996. These increases primarily reflect
the increases in personnel required to support the Company's revenue growth and
increases in agent and sales representative commissions. Sales and marketing
expense fluctuated as a percentage of revenue from 13.4% in fiscal 1994 to 20.9%
in fiscal 1995 and 23.1% in fiscal 1996. The Company expects sales and marketing
expense to increase in absolute dollars in future periods as the Company expands
its sales and marketing efforts. The expected increase in the Company's sales
and marketing expense could have a material adverse effect on the Company's
business, operating results and financial condition if the Company's revenue
does not also increase.
    
 
   
     General and administrative.  General and administrative expense increased
from $827,000 in fiscal 1994 to $1.1 million in fiscal 1995 and to $2.0 million
in fiscal 1996. The increases in general and administrative expense in each
period resulted primarily from the addition of new management and administrative
personnel and increased administrative costs to support the Company's growth. As
a percentage of revenue, general and administrative expense decreased from 17.8%
in fiscal 1994 to 16.5% in fiscal 1995 and 13.1% in fiscal 1996 as revenue
increased in each period. The Company expects general and administrative expense
to increase in absolute dollars in future periods as the Company expands its
operations.
    
 
   
     Provision for income taxes.  The Company's tax rates of 40.0%, 40.0% and
41.0% in fiscal 1994, 1995 and 1996, respectively, approximate the combined
federal and state statutory income tax rates.

     The Company's revenue increased on a quarterly basis from the first quarter
of fiscal 1995 to the first quarter of fiscal 1997, except for a slight decrease
from the fourth quarter of fiscal 1995 to the first quarter of fiscal 1996.
Revenue in the third quarter of fiscal 1996 increased from the second quarter of
fiscal 1996 because of increased revenue from gate array products sold to
merchant ASIC customers. Revenue continued to grow in the fourth quarter of
fiscal 1996 and the first quarter of fiscal 1997 primarily because of increased
revenue from standard cell-based DIT products sold to new customers.
    
 
   
     Cost of revenue increased on a quarterly basis from the first quarter of
fiscal 1995 to the first quarter of fiscal 1997. As a percentage of revenue,
cost of revenue has fluctuated over this period but
    
 
                                       19
<PAGE>   21
 
   
generally has declined as a percentage of revenue. The reduction in cost of
revenue as a percentage of revenue after the second quarter of fiscal 1996
reflects increased revenue from products that did not require significant
adaptation.
    
 
   
     Research and development expense generally increased in absolute dollars
over the nine quarter period. As a percentage of revenue, research and
development expense has fluctuated but generally has declined after the second
quarter of fiscal 1996 due to rapid revenue growth. The Company expects research
and development expense to increase in absolute dollars over future periods as
it expands its engineering efforts.
    
 
   
     Sales and marketing expense increased in each of the nine quarters as the
Company established a North American direct sales force and relationships with
distributors and sales representatives in North America and Asia. Sales and
marketing expense increased substantially in the third and fourth quarters of
fiscal 1996 and the first quarter of fiscal 1997 due to increased personnel
costs, commissions paid to sales representatives in Taiwan and Singapore and
increased commissions paid to employees in North America associated with
increased revenue in those periods. In addition, sales and marketing expense
increased in the first quarter of fiscal 1997 due to increased personnel as
certain general and administrative personnel were transferred into sales and
marketing.
    
 
   
     General and administrative expense generally increased in absolute dollars
as the Company increased its administrative efforts to manage its growth and
decreased as a percentage of revenue due to more rapidly increasing revenue in
the quarters shown. General and administrative expense declined in both absolute
dollars and as a percentage of revenue in the first quarter of fiscal 1997 due
to reduced personnel and other administrative costs as certain personnel were
transferred into sales and marketing.
    
 
     Interest income increased substantially in the third quarter of fiscal 1996
because of interest on the proceeds of sales of the Company's stock. Interest
income decreased in the fourth quarter of fiscal 1996 as the Company used funds
to repurchase common stock.
 
     The Company's operating results have fluctuated in the past and are
expected to fluctuate significantly from quarter to quarter and on an annual
basis in the future as a result of a number of factors including the size and
timing of customer orders; the Company's ability to achieve progress on
percentage of completion contracts; the length of the Company's sales cycle;
timing of new product announcements and introductions by the Company and its
existing or future competitors; the Company's ability to develop, introduce and
market new products and product enhancements; market acceptance of the Company's
products; and general economic conditions. The Company's future operating
results are expected to fluctuate as a result of these and other factors, which
could have a material adverse effect on the Company's business, operating
results and financial condition. 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.
 
   
     A substantial majority of the Company's revenue is recognized on a
percentage of completion method based upon actual costs incurred. The completion
period typically ranges from three months to a year. Accordingly, revenue in any
quarter is dependent on progress towards completion of the project by the
Company. The Company has in the past experienced delays in the progress of
certain projects and there can be no assurance that such delays will not occur
with respect to future projects. Any delay or failure to achieve such progress
could result in damage to customer relationships and the Company's reputation,
diversion 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,
these contracts may generally be cancelled 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 "Risk Factors -- Fluctuations in Future Operating Results;
Dependence Upon Timely Project Completion."

INTRODUCTION
 
   
     Aspec is a leading independent provider of commercially available DIT
solutions for IC design. DIT consists of libraries of electrical circuits, often
called cell libraries, based on proprietary architectures, and a design
methodology, which together enable IC designers to implement the physical design
of an IC in silicon. Aspec's DIT supports many leading EDA tools and advanced
process technologies at leading semiconductor foundries. Aspec's DIT is designed
to: (i) facilitate the rapid design of complex, high-performance ICs in advanced
process technologies, (ii) provide an integrated design solution that increases
productivity, (iii) preserve existing EDA investments and (iv) allow customers
to access multiple foundries for cost control and alternate sourcing. Aspec's
DIT provides designers with quick access to accurate and complete cell libraries
at a lower cost than developing an equivalent internal solution. Aspec's DIT
includes its AdverPro design verification software which enables EDA tools to
exchange data while maintaining design intent, provides an accurate timing
function across EDA tools and helps to ensure compliance with proper design
procedures.
    
 
INDUSTRY BACKGROUND
 
     Semiconductors have become a critical component of technology in numerous
electronic products manufactured today. Advances in semiconductor technology
have contributed to the rapid proliferation of personal computers, consumer
electronics, networking equipment, cellular telephones and other communications
devices, as well as a variety of medical, scientific and industrial instruments.
Moreover, complex electronics products continue to be introduced at rapid rates
while increasing worldwide competition continues to shorten product life cycles.
These developments have driven continued improvements in IC design methodologies
and manufacturing process technologies, enabling the design and fabrication of
smaller, faster, more complex ICs that are produced more rapidly and at a lower
cost per function. These trends have also resulted in a significant change in
the semiconductor industry as fewer IC companies are adopting a vertically
integrated approach to design and manufacturing and are instead relying on
third-party specialists for their EDA tools and semiconductor foundries for
their manufacturing needs.
 
     The emergence of ASIC companies in the 1980s is a key example of
specialization in the semiconductor industry. Prior to this emergence,
semiconductor companies were typically vertically integrated and were
responsible for all aspects of the IC development process from design to
manufacturing. ASIC companies developed a new approach that allowed their
customers to define the functional logic of an IC while the ASIC company
performed the physical level design and manufactured the IC.
 
     The ASIC design model relies upon EDA tools, captive wafer foundries and a
process for implementing the physical design in silicon. This process is known
as DIT. DIT consists of (i) a set of electrical circuit libraries, (ii) a common
design architecture upon which these libraries are based and (iii) an overall
design methodology. The circuit libraries define the physical and operating
parameters of the individual logic elements which are the core building blocks
of an IC. These libraries are based on a proprietary architecture that consists
of a set of circuit-level design rules which specify certain key operating and
physical characteristics of the individual electrical components which comprise
these logic elements. The quality of the architecture determines in large part
the circuit's operating performance and power consumption and its ability to
perform as expected when implemented in silicon. The design methodology is a set
of chip-level design guidelines and rules that determine how the circuit
libraries are used in conjunction with EDA tools
 
                                       23
<PAGE>   25
 
to produce the IC design in silicon. The quality of the design methodology
substantially determines the IC designer's ability to successfully complete the
design and provide for successful manufacturing in a timely manner. The success
that ASIC companies experienced using DIT-based design models influenced
traditional IC companies to adopt a similar model. Today virtually every IC is
developed using EDA tools and DIT.
 
     The following chart illustrates the IC design process and how DIT forms an
integral part of this process:
 
        [A graphical diagram appears here that depicts the steps in the
                                IC manufacturing
         process and how EDA tools and DIT interact with such process.]
 
     Development of a DIT requires highly specialized expertise in IC design,
EDA tools and foundry processes and is complicated for a number of reasons.
First, each step in the IC design process requires at least one specialized EDA
tool, and a complex design typically requires more than ten different tools.
Each EDA tool uses the circuit libraries to perform its analysis. However, each
EDA tool utilizes the same base library in a different format and, therefore, a
design may require access to more than 30 different formats of libraries.
Additionally, each IC designer usually selects EDA tools from different vendors
to optimize the requirements of a specific design process. However, different
tools do not easily interface with each other. Thus, a DIT must also effectively
manage the interrelationship among multiple EDA tools.
 
                                       24
<PAGE>   26
 
     In addition, DIT must be reconfigured for each semiconductor process
technology and also for each semiconductor manufacturer used by the IC designer.
For example, to migrate from a manufacturer's 0.5m to a 0.35m process, each
library must be reconfigured, which requires reoptimization of circuit size and
physical layout. This reconfiguration involves significant engineering resources
and time to complete. The reconfiguration process becomes especially complex for
deep submicron designs, which are required to satisfy the demands of smaller,
faster and more complex ICs.
 
     IC designers utilize various methods to meet their DIT requirements. ASIC
vendors and IC companies typically rely on internally developed DIT solutions.
Electronic systems manufacturers such as PC companies rely on ASIC companies for
DIT. However, it is becoming increasingly difficult for these methods to meet
the challenges of increased design complexity and increased time-to-market
pressures which confront IC designers. ASIC vendors and IC companies are also
finding it increasingly impracticable, costly and time consuming to develop and
maintain their own proprietary DIT. In addition, ASIC vendors and IC companies
find it increasingly difficult to allocate sufficient resources to DIT as more
and more resources are required for complex semiconductor design. Electronic
systems manufacturers are finding it desirable to control the intellectual
property content of their designs, to more rapidly adopt new process
technologies and effectively integrate the various steps in their design flows
and, consequently, to decrease the time-to-market for their products. Thus,
these companies are increasingly seeking a third-party solution to their DIT
requirements.
 
ASPEC SOLUTION
 
   
     Aspec is a leading independent provider of commercially available DIT
solutions for IC design. Aspec's DIT supports many leading EDA tools and
advanced process technologies at leading semiconductor foundries. Aspec's DIT is
designed to: (i) facilitate the rapid design of complex, high-performance ICs in
advanced process technologies, (ii) provide an integrated design solution that
increases productivity, (iii) preserve existing EDA investments and (iv) allow
customers to access multiple foundries for cost control and alternate sourcing.
The Company also believes its DIT enables IC companies to create high quality,
reliable and high performance ICs while reducing time-to-market and lowering
production and design costs. Aspec's DIT solution provides quick access to
accurate and complete cell libraries at lower cost than developing an equivalent
internal solution. Aspec's DIT also includes its AdverPro design verification
software which enables EDA tools to exchange data while maintaining design
intent, provides an accurate timing function across EDA tools and helps to
ensure compliance with proper design procedures. Aspec's DIT is also designed to
facilitate the porting of circuit designs to different foundries and process
technologies quickly and at reduced cost, which can be accomplished using
Aspec's QuickPort software. The Company believes its products provide the
following benefits:
    
 
     Access to Sophisticated Process Technology.  Companies obtain access to
advanced process technology quickly and cost effectively by licensing Aspec's
DIT. By selecting a commercial solution, companies are able to dedicate more of
their internal engineering resources to semiconductor design. Aspec reconfigures
and optimizes its architecture and libraries for leading foundries and IC
manufacturers.
 
     Control of Intellectual Property and Design.  With Aspec's DIT, IC
designers can establish a standard DIT for all of their design processes and
maintain ownership of the intellectual property content of their designs.
Aspec's DIT also enables electronic systems manufacturers to exercise control
over their designs instead of relying on ASIC companies to control the design
process. This control is especially critical as the time-to-market for new
products continues to contract.
 
     Support of Leading EDA Software Tools.  Aspec's DIT supports many leading
third-party EDA tools including those from Avant! Corporation ("Avant!"),
Cadence Design Systems, Inc. ("Cadence"), Epic Design Technology, Inc. ("Epic"),
Mentor Graphics Corp. ("Mentor"), Synopsys
 
                                       25
<PAGE>   27
 
Inc. ("Synopsys") and Viewlogic Systems Inc. ("Viewlogic"). This open DIT
structure enables EDA tools from different vendors to interface with one another
and permits an IC designer to select the best tool for each step in the design
process. Aspec's DIT also enables an IC designer to exchange data between
different design processes even if different tools are used in each flow. By
supporting a range of EDA tools, Aspec enables an IC designer to preserve the
substantial investment made to acquire such tools.
 
     Facilitation of Deep Submicron Design.  Aspec's DIT helps ensure that EDA
tools and design processes work together to design complex deep submicron ICs.
As an integral part of its DIT, Aspec's AdverPro software provides the interface
that enables EDA tools to exchange data while maintaining design intent. As part
of this interface, AdverPro is designed to provide an accurate timing function
across EDA tools which is a critical requirement for deep submicron design.
Aspec's DIT is also designed to help to ensure compliance with proper design
procedures and enables the IC designer to develop a logic description which is
qualified for physical layout.
 
   
     Design Portability.  Aspec's DIT is designed to enable circuit designs to
be transferred from one process technology to another. The increasing demand for
semiconductor manufacturing capacity and access to advanced process technology
has created a strong demand for second sourcing alternatives. However, the
process of reconfiguring a design to a new manufacturing source may require many
weeks of engineering time. Aspec's QuickPort software can significantly reduce
this reconfiguration time by providing IC designers with the flexibility to port
their designs across multiple foundries and process technologies.
    
 
STRATEGY
 
   
     The Company's objective is to expand its position as a leading independent
provider of commercial DIT solutions for the semiconductor industry. To achieve
this objective, the Company has adopted the following strategies:
    
 
     Establish Aspec DIT as an Industry Standard.  Aspec believes it was one of
the first companies to deliver commercial DIT solutions for the semiconductor
industry and is committed to establishing its DIT as an industry standard.
Aspec's DIT provides an open solution by supporting many leading EDA tools and
process technologies at leading semiconductor foundries. The Company's DIT
allows its customers to complete their designs rapidly and precisely, to
preserve their existing investment in EDA tools and to utilize cost-effectively
multiple foundries. Aspec believes its DIT is well-positioned to become an
industry standard because many of its existing and potential competitors are
dedicated to one EDA tool supplier.
 
   
     Maintain Technological Leadership.  Aspec's goal is to maintain its
position as an independent leader in providing commercial DIT solutions by
rapidly developing new versions of its products to support the most advanced EDA
tools and emerging deep submicron process technologies. The Company is
continuing to enhance its DIT and to add functionality to its AdverPro software
to meet the challenges of new processes. Aspec is also developing selected
specialized software tools that enhance its DIT and is developing a process that
facilitates the creation of enhanced cell libraries. The Company intends to
continue to recruit and retain key technical personnel who have the experience
and skills to strengthen Aspec's position as an independent leader in commercial
DIT development.
    
 
     Broaden Customer Base.  Aspec's goal is to expand its customer base by
leveraging the products and expertise it initially developed to meet the
requirements of vertically integrated semiconductor companies that were seeking
to enter the merchant ASIC market. Specifically, the Company is targeting its
sales and marketing efforts towards fabless semiconductor companies that have
historically relied on internal resources to meet their DIT needs. Due to the
increasing cost of such proprietary DITs and the shortening product life cycles
for their products, Aspec believes that these companies will increasingly seek a
third-party solution to their DIT requirements. Aspec is also targeting
electronic systems manufacturers that currently rely on ASIC vendors for DIT. By

utilizing Aspec's DIT, electronic systems manufacturers can more effectively
control the intellectual property content of their designs.
 
     Promote Long-Term Commercial Relationships.  A key element of Aspec's
strategy is to cultivate long-term relationships with its customers, leading
semiconductor foundries and EDA tool companies. Aspec believes that
relationships with key industry participants will enhance its ability to
establish its DIT as an industry standard. The Company emphasizes commercial and
technical discussions to receive feedback on products, support and market
requirements. The Company believes the breadth and quality of this information
is a valuable source of strategic direction and validation.
 
PRODUCTS AND SERVICES
 
   
     Aspec markets a suite of DIT products on a per design basis, a per site
basis or an enterprise basis to its customers. These products include electrical
circuit libraries, memory compilers and AdverPro. Typically a customer licenses
a bundle of products which is accompanied by design methodology documentation
and training. These products are also licensed separately. Aspec's DIT products
include licenses for libraries for logic functions based on gate array/embedded
array or standard cell architectures, input/output ("I/O") functions, compilers
to automatically generate memory blocks and software that ensures that various
commercially available EDA tools work together to accurately produce the IC
design in silicon. In addition, Aspec provides software that enables the
portability of designs as well as various design services and consulting to its
DIT licensees on a per project basis. The Company's products, which run on UNIX
workstations and Windows NT-based PCs, support over 30 industry standard EDA
tools, including those produced by Avant!, Cadence, Epic, Mentor, Synopsys and
Viewlogic.
    
 
     A description of the Company's principal products and services is provided
below:
 
          HDA Libraries.  High Density Array ("HDA") is Aspec's proprietary,
     patented gate array/ embedded array architecture for silicon processes from
     0.8m to 0.35m and smaller. Benchmarks have shown HDA to be 10% to 50%
     denser than competitive offerings. In addition, various HDA circuit design
     features enable designers to complete the layout of the design faster than
     other gate array architectures. With an HDA license, the customer obtains
     access to silicon process optimized libraries for commonly used logic
     functions, such as Boolean logic.
 
          HDC Libraries.  High Density Cell ("HDC") is Aspec's proprietary
     standard cell architecture for silicon processes from 0.6m to 0.5m.
     Compared to other proprietary or commercially available standard cell
     libraries, Aspec's HDC requires less interconnection (routing) overhead. As
     a result, not only is an HDC-based IC smaller than competitive offerings,
     it is also faster and requires less power. With an HDC license, the
     customer obtains access to silicon process optimized libraries for commonly
     used logic functions.
 
          SSC Libraries.  Super Standard Cell ("SSC") is Aspec's recently
     introduced, proprietary standard cell architecture for deep submicron
     processes from 0.35m and smaller. When using the same process technology,
     SSC libraries will usually be 15% smaller than Aspec's HDC libraries. In
     addition, ICs implemented in SSC libraries will consume less power and
     yield higher performance, due to library features that are designed to take
     advantage of silicon processes from 0.35m and smaller. With an SSC license,
     the customer obtains access to silicon process optimized libraries for
     commonly used logic functions.
 
          I/O Circuit Libraries.  Aspec offers a set of silicon process
     optimized circuit libraries for commonly used I/O functions for silicon
     processes from 0.8m to 0.35m and smaller. These I/O libraries enable Aspec
     customers to provide interconnection to other ICs in the system. As these
     interconnections have become more application specific, Aspec has developed
     specialized I/O libraries for these interfaces.
 
                                       27
<PAGE>   29
 
          Each of these cell and I/O libraries is licensed on a per silicon
     process basis, and prices range from $100,000 to over $800,000.
 
          Memory Compilers.  Most IC designs contain large blocks of memory to
     store data. Aspec offers various memory compilers which automate the
     process of creating these memory blocks. As with all other libraries, the
     memory compilers are optimized for each silicon process. Prices for memory
     compilers range from $100,000 to $450,000.
 
   
          EDA Design Kits.  In the IC development process, the designer uses
     many EDA tools. Each of these EDA tools requires that the HDA/HDC/SSC
     libraries, I/O libraries and memory blocks be described in a way that is
     understood by the EDA tools. Collectively, these different representations
     are called EDA Design Kits. Aspec's EDA Design Kits can support more than
     30 different EDA tools. EDA Design Kits are typically licensed with cell
     and I/O libraries. The price of each EDA Design Kit ranges from $10,000 to
     over $250,000, depending upon how many EDA tools are supported.
    
 
          AdverPro.  Aspec's AdverPro software is designed to manage the design
     process, provide an accurate timing function across EDA tools and help
     ensure compliance with proper design procedures. AdverPro is sold as
     licensed software, and its price ranges from $45,000 for a single user
     license to over $1,000,000 for an enterprise license.
 
          QuickPort.  Aspec's QuickPort software is designed to enable an IC
     company to economically and timely port a design developed in Aspec's DIT
     from one silicon process to another. QuickPort also enables the transfer of
     circuit designs from one IC to another by providing for the reuse of
     designs developed in Aspec's DIT. QuickPort is sold as licensed software,
     and its price ranges from $100,000 for a single user license to $500,000
     for an enterprise license.
 
          ASIC Design Service.  Aspec maintains a design center to test the
     functionality of its software and to assist customers that lack experience
     in completing full circuit designs. These design services are offered on a
     per project basis.
 
  Foundry Processes Supported by Aspec
 
     Aspec's DIT supports many of the world's leading semiconductor foundries,
including Chartered Semiconductor Manufacturing Ltd., International Business
Machines Corp. ("IBM"), Taiwan Semiconductor Manufacturing Corp. ("TSMC") and
United Microelectronics Corporation ("UMC"), thus offering its customers a wide
variety of manufacturing sources. Aspec's DIT products are generally licensed on
a per process technology basis and are available to support submicron processes
from 0.8m to 0.35m, depending on the foundry.
 
CUSTOMERS
 
   
     Aspec's principal customers include vertically integrated semiconductor
companies, fabless semiconductor companies and semiconductor foundries. The
Company has been dependent on a relatively small number of customers for a
substantial portion of its annual revenue. In fiscal 1994, Thesys, Sanyo,
Hyundai and Samsung accounted for 28.9%, 21.3%, 19.3% and 12.7%, respectively,
of the Company's revenue. In fiscal 1995, Samsung, NSC and Yamaha accounted for
18.2%, 17.3% and 15.1%, respectively, of the Company's revenue. In fiscal 1996,
Asahi Glass accounted for 10.5% of the Company's revenue, and the Company's six
largest customers accounted for 51.8% of the Company's revenue. The Company
anticipates that the majority of its revenue will be derived from a relatively
small number of customers through fiscal 1997. None of the Company's customers
has a written agreement with the Company that obligates it to license additional
products or to renew its maintenance agreement, and there can be no assurance
that any customer will purchase additional software licenses or renew its
maintenance agreement. See "Risk Factors -- Customer Concentration."

SALES AND MARKETING
 
   
     The Company's current and potential customers are principally located in
North America, Japan, Korea and parts of Asia. The Company markets its products
in North America, Japan and Korea primarily through its direct sales force. The
Company employs highly skilled engineers and technical sales persons capable of
serving the sophisticated needs of its customers. In addition to its direct
sales and marketing efforts, the Company participates in industry trade shows
and seminars to promote the adoption of its products. In parts of Asia and
Europe, the Company markets its products primarily through a limited number of
independent distributors that license and service the Company's products in
these markets. The Company also supports these distributors with technical,
sales and management personnel. The Asian and European countries that have
constituted the primary foreign markets for the Company's products are Korea,
Japan, Taiwan, Singapore and Germany.
    
 
   
     International revenue accounted for 83.7%, 54.2% and 66.2% of the revenue
in fiscal 1994, 1995 and 1996, respectively. The Company expects that
international revenue will continue to account for a significant portion of its
revenue in the future. The Company intends to continue to expand its sales and
marketing activities in Asia and Europe. The Company's 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 distributors and
customers, difficulty in managing distributors or sales representatives,
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 licensing and service or that the foregoing factors will not
have a material adverse effect on the Company's business, operating results and
financial condition. Although the Company prices its products and services in
United States dollars, currency exchange fluctuations in countries in which the
Company licenses its products could have a material adverse effect on the
Company's business, operating results and financial condition by resulting in
pricing that is not competitive with products priced in local currencies. The
Company does not hedge against foreign currency fluctuations. See "Risk
Factors -- Risks Associated With International Operations."
    
 
     The Company licenses its software to customers under nonexclusive
agreements that do not transfer title and that restrict use of the products to
specified purposes. The Company offers customers the option of licensing its
products enterprise-wide or for use at a particular site or on
 
                                       29
<PAGE>   31
 
designated computers at specific sites. License fees are dependent on the type
of license, product mix and number of copies of each product subject to the
license.
 
CUSTOMER SUPPORT
 
     The Company provides customers with technical support as well as training
and consulting services. The Company believes that a high level of customer
service and support is important to the adoption and successful utilization of
its products. The Company's customers typically pay an additional fee for
maintenance agreements that entitle them to technical support and periodic
product upgrades. The Company also offers additional training and consulting
services on a fee basis. To address technical issues, the Company has
established a technical support group comprised of field and headquarters
applications engineers who understand the design methodologies of the Company's
customers. Through its technical support group, the Company provides customers
with software updates, documentation updates and assistance with problem
identification and resolution.
 
RESEARCH AND DEVELOPMENT
 
     The Company believes that its future competitive position will depend in
large part on its ability to quickly and cost effectively develop new products,
maintain and enhance its current product line, maintain technological
competitiveness and meet an expanding range of customer requirements. During
fiscal 1994, 1995 and 1996, research and development expenses were $289,000,
$445,000 and $921,000, respectively. Aspec is committed to devoting significant
resources to research and development. To date, all software development costs
have been expensed as incurred. The Company's research and development efforts
are focused on continued development of proprietary cell architecture,
enhancements to existing software designs and support of additional design
flows.
 
     The Company's customers operate in the semiconductor industry, which is
subject to rapid technological change, frequent introductions of new products,
short product life cycles, changes in customer demand and requirements and
evolving industry standards. 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 product introductions by EDA tool
companies, emerging process technologies and other technological developments in
the semiconductor industry. Any failure by the Company to anticipate or respond
adequately to changes in technology 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 be successful in its product
development efforts, 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. The Company has in the past experienced delays in the release dates
of certain of its products. If release dates of any new significant products or
product enhancements are delayed, the Company's business, operating results and
financial condition would be materially adversely affected. The Company could
also be exposed to litigation or claims from its customers in the event it does
not satisfy its delivery commitments. There can be no assurance that any such
claim will not have a material adverse effect on the Company's business,
operating results and financial condition. See "Risk Factors -- Dependence Upon
Continuous Product Development; Risk of Product Delays."
 
COMPETITION
 
     The market for commercial DIT products is new and emerging, and the Company
has few direct competitors. The Company principally competes with the
engineering departments of potential customers that develop and maintain
internally developed DIT. Certain of the Company's other
 
                                       30
<PAGE>   32
 
   
potential customers rely on proprietary DIT developed and maintained by ASIC
vendors. Although the Company believes that none of its competitors offer a
complete DIT solution, the Company's current competitors with respect to one or
more aspects of its DIT solution include Cascade, Compass, Si-Arc and Artisan.
In addition, certain semiconductor foundries currently offer or may in the
future offer one or more elements of a DIT solution. The Company does not offer
EDA tools, and its products are designed to be compatible with leading EDA
tools. The Company expects that the market for its products will become
increasingly competitive in the future. Among the Company's potential
competitors are a number of large vertically integrated semiconductor companies
and numerous EDA software companies that may develop products that compete with
those of the Company. Increased competition could eventually result in price
reductions or reduced operating margins which could materially adversely affect
the Company's business, operating results and financial condition. Many of the
Company's potential competitors have significantly greater financial, technical,
marketing and other resources than the Company. As a result, they may be able to
respond more quickly to new or emerging technologies and to changes in customer
requirements, or to devote greater resources to the development, promotion and
sale of their products than can the Company. There can be no assurance that the
Company will be able to compete successfully against current or future
competitors or that competitive pressures will not materially adversely affect
the Company's business, operating results and financial condition. The Company
believes the principal elements of competition in its market are the range of
EDA tools and process technologies supported, technological leadership, product
functionality, the level of technical support provided, software reliability and
price. The Company believes that it competes favorably with respect to each of
these factors. See "Risk Factors -- Competition."
    
 
PROPRIETARY RIGHTS
 
     The Company's success is dependent on its ability to protect its
proprietary technology. The Company relies upon a combination of copyright,
patent, trade secret and trademark laws to protect its proprietary technology.
The Company enters into confidentiality agreements with its employees,
distributors and customers and limits access to and distribution of the source
code to its software and other proprietary information. There can be no
assurance that the steps taken by the Company in this regard will be adequate to
prevent misappropriation of its technology or that the Company's competitors
will not independently develop technologies that are substantially equivalent or
superior to the Company's technology. Any such misappropriation of the Company's
technology or development of competitive technologies could have a material
adverse effect on the Company's business, operating results and financial
condition. Despite the Company's efforts to protect its proprietary rights,
there can be no assurance that the Company will be able to protect its
proprietary rights against unauthorized third party copying or use, and attempts
may be made to copy or reverse engineer aspects of the Company's products or to
obtain and use information that the Company regards as proprietary. Policing the
unauthorized use of the Company's products is difficult and the Company could
incur substantial costs in protecting and enforcing its intellectual property
rights. Litigation may be necessary in the future to enforce the Company's
intellectual property rights, to protect the Company's trade secrets or to
determine the validity and scope of the proprietary rights of others. Such
litigation could result in substantial costs and diversion of resources and
could have a material adverse effect on the Company's business, operating
results and financial condition.
 
   
     As of February 28, 1997, the Company held three U.S. patents which expire
from 2012 to 2013 and had six U.S. patent applications pending. The Company also
has 13 patent applications pending in various foreign jurisdictions. The Company
expects to continue to file patent applications where appropriate to protect its
proprietary technologies; however, the Company believes that its continued
success depends primarily on factors such as the technological skills and
innovation of its personnel rather than on its patents. The Company has
registered the trademarks Aspec Technology and Mastergen and has four trademark
applications pending in the United States. The process of seeking patent and
trademark protection can be expensive and time consuming. There can be no
assurance that patents or trademarks will issue from pending or future
applications or that, if issued,
    
 
                                       31
<PAGE>   33
 
   
such patents or trademarks will not be challenged, invalidated or circumvented,
or that rights granted thereunder will provide meaningful protection or other
commercial advantage to the Company. Moreover, there can be no assurance that
any patent or trademark rights will be upheld in the future or that the Company
will be able to preserve any of its other intellectual property rights. In
addition, the laws of certain countries in which the Company's products are
licensed or distributed do not protect the Company's products and intellectual
property rights to the same extent as the laws of the United States.
Accordingly, effective trademark, copyright and patent protection may be
unavailable in certain foreign countries.
    
 
     As is common in the software industry, the Company may from time to time
receive notices from third parties claiming infringement by the Company's
products of third-party proprietary rights. While the Company is not currently
subject to any such claim, the Company believes that its products could
increasingly be subject to such claims as the market for its products grows and
as more competitors enter the market. Any such claim, with or without merit,
could result in significant litigation costs and require the Company to enter
into royalty and licensing agreements, which could have a material adverse
effect on the Company's business, operating results and financial condition.
Such royalty and licensing agreements, if required, may not be available on
terms acceptable by the Company or at all. See "Risk Factors -- Limited
Protection of Proprietary Rights."
 
EMPLOYEES
 
   
     As of February 28, 1997, the Company had 100 employees, including 60 in
operations, 13 in research and development, 20 in sales and marketing and 7 in
finance and administration. None of the Company's employees is represented by a
collective bargaining agreement, nor has the Company experienced any work
stoppage. The Company considers its relations with its employees to be good.
    
 
FACILITIES
 
     The Company occupies approximately 29,000 square feet of office space in
Sunnyvale, California, pursuant to a lease which expires in November 2001. The
Company believes that its existing facility is adequate for its current needs
but that it may need to seek additional space in the future. The Company
believes that suitable additional or alternative space will be available in the
future on commercially reasonable terms as needed.

     Mr. Dell'Oca has served as President and a director of the Company since
January 1992 and as Chief Executive Officer of the Company since February 1992.
In addition, since February 1997, Mr. Dell'Oca has served as Chairman of the

director compensation and participation in the Director Plan, outside directors
are defined as directors who are not employees of the Company and are not
partners or members of any venture capital firm or institutional investor which
owns securities of the Company having more than five percent of the total voting
power of the Company. A total of 250,000 shares of Common Stock has been
reserved for issuance under the Director Plan. As
    
 
                                       35
<PAGE>   37
 
   
of February 28, 1997, options to purchase an aggregate of 25,000 shares of
Common Stock were outstanding under the Director Plan, and an aggregate of
225,000 shares of Common Stock remained available for future grants. The
Director Plan provides for the grant of nonstatutory stock options to outside
directors of the Company pursuant to an automatic, nondiscretionary grant
mechanism. The Director Plan provides that each outside director, except for
employee directors who become outside directors, shall be granted a nonstatutory
stock option to purchase 25,000 shares of Common Stock on the date upon which
such person first becomes an outside director (the "First Option"). Thereafter,
each outside director shall be automatically granted an option to purchase 5,000
shares of Common Stock upon his or her reelection to the Board on the date of
the Company's annual meeting of stockholders of each year (a "Subsequent
Option"), if on such date such outside director shall have served on the
Company's Board of Directors for at least six (6) months. The Director Plan
provides that each option shall become exercisable as to 25% of the shares
subject to the option on the day before the date of the Company's annual meeting
of stockholders of each year as long as the optionee remains a director. The
exercise price per share of all options granted under the Director Plan shall be
equal to the fair market value of a share of the Company's Common Stock on the
date of grant. Options granted to Outside Directors under the Director Plan have
a ten year term, but will expire unless exercised within three months following
the termination of an Outside Director's status as a director. In the event of
the merger or sale of substantially all of the assets of the Company, all
outstanding options shall be assumed or substituted by the successor
corporation, or if they are not assumed or substituted, they shall become fully
vested and exercisable. If not terminated earlier, the Director Plan will have a
term of ten years. Directors are also eligible to receive stock options under
the Option Plan. Pursuant to the Director Plan, Mr. Saper was granted an option
to purchase 25,000 shares at an exercise price of $8.50 per share on February
25, 1997. See "Management -- Compensation Plans."

OPTION GRANTS IN LAST FISCAL YEAR
 
     The Company did not grant stock options to any of the Named Executive
Officers during the fiscal year ended November 30, 1996. In addition, none of
the Named Executive Officers held options or exercised options during the fiscal
year ended November 30, 1996.
 
COMPENSATION PLANS
 
     1996 Stock Option Plan
 
   
     The Company's Option Plan was approved by the Board of Directors and the
stockholders in June 1996 and was amended in February 1997. The 1996 Plan
provides for the grant to employees of the Company (including officers and
employee directors) of incentive stock options within the meaning of Section 422
of the Internal Revenue Code of 1986, as amended (the "Code"), and for the grant
of nonstatutory stock options to employees, directors and consultants of the
Company. The Option Plan is currently administered by the Compensation Committee
of the Board of Directors (the "Administrator"), which selects the optionees,
determines the number of shares to be subject to each option and determines the
exercise price of each option. The Option Plan authorizes the issuance of an
aggregate of up to 4,500,000 shares of Common Stock. As of February 28, 1997,
    
 
                                       37
<PAGE>   39
 
   
options to purchase an aggregate of 1,117,100 shares of Common Stock were
outstanding under the Option Plan, and an aggregate of 3,382,900 shares of
Common Stock remained available for future grants. The exercise price of all
incentive stock options granted under the Option Plan must be at least equal to
the fair market value of the Common Stock on the date of grant. The exercise
price of all nonstatutory stock options granted under the Option Plan shall be
determined by the Administrator. With respect to any participant who owns stock
possessing more than 10% of the voting power of all classes of stock of the
Company, the exercise price of any incentive stock option granted must equal at
least 110% of the fair market value on the grant date and the maximum term of
the incentive stock option must not exceed five years. The term of all other
options granted under the Option Plan may not exceed ten years.
    
 
     In the event of a merger of the Company with or into another corporation or
a sale of substantially all of the assets of the Company, the Option Plan
requires that each outstanding option be assumed or an equivalent option
substituted by the successor corporation; provided, however, that in the event
the successor corporation refuses to assume or substitute for the outstanding
options, such options will become fully vested and exercisable for a period of
fifteen days after notice from the Administrator. Unless terminated sooner, the
Option Plan will terminate ten years from its effective date. The Board has
authority to amend or terminate the Option Plan, provided that no such action
may impair the rights of the holder of any outstanding options without the
written consent of such holder.
 
     1997 Employee Stock Purchase Plan
 
     The Company's Purchase Plan was approved by the Board of Directors in
February 1997 and will become effective upon the closing of the offering. A
total of 500,000 shares of Common Stock has been reserved for issuance under the
Purchase Plan. The Purchase Plan is intended to qualify under Section 423 of the
Code. The Purchase Plan includes offering periods lasting six months with a new
offering period commencing every six months. The initial offering period will
commence on the date of the offering and end on the last business day on or
prior to September 30, 1997, and subsequent offering periods are initially
expected to be from October 1 to March 31 and April 1 to September 30 of each
year. Employees are eligible to participate if they are regularly employed by
the Company for at least twenty hours per week and 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 10% of an employee's base
compensation, including commissions, bonuses and overtime, at a price equal to
85% of the fair market value of the Common Stock at the beginning of each
offering period or the last date of the offering period, whichever is lower. In
the event of a merger of the Company into another corporation or a sale of
substantially all of the assets of the Company, the Purchase Plan provides that
the Board of Directors will shorten the offering period by setting a new
exercise date to occur before the proposed sale or merger. Unless terminated
sooner, the Purchase Plan will terminate ten years after its effective date. The
Board of Directors has authority to amend or terminate the Purchase Plan
provided no such action may adversely affect the rights of any participant.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     The Company's Certificate of Incorporation limits the liability of
directors to the fullest extent permitted by the Delaware General Corporation
Law (the "Delaware Law"). Under the Delaware Law, a director's liability to a
company or its stockholders may not be limited with respect to (i) any breach of
his duty of loyalty to the Company or its stockholders, (ii) acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) unlawful payments or dividends or unlawful stock repurchases or
redemptions or (iv) transactions from which the director derived an improper
personal benefit.
 
                                       38
<PAGE>   40
 
     The Company's Bylaws provide that the Company shall indemnify its officers
and directors and may indemnify its employees and other agents to the fullest
extent permitted under the Delaware Law. The Company has also entered into
agreements to indemnify its directors and executive officers, in addition to the
indemnification provided for in the Company's Bylaws. The Company believes that
these provisions and agreements are necessary to attract and retain qualified
directors and executive officers. The Company's Bylaws also permit it to secure
insurance on behalf of any officer, director, employee or other agent for any
liability arising out of his or her actions, regardless of whether the Delaware
Law would permit indemnification. In addition, the Company maintains directors'
and officers' liability insurance.
 
     There is no pending litigation or proceeding involving any director,
officer, employee or agent of the Company where indemnification will be required
or permitted. The Company is not aware of any pending or threatened litigation
or proceeding that might result in a claim for such indemnification.

of Series A Redeemable Preferred Stock. See "Use of Proceeds." The Series A
Redeemable Preferred Stock is not convertible into Common Stock. Summit Ventures

                          DESCRIPTION OF CAPITAL STOCK
 
     After giving effect to the reincorporation of the Company in the State of
Delaware prior to the date of this Prospectus, the authorized capital stock of
the Company will consist of 75,000,000 shares of Common Stock, par value $0.001
per share, and 5,000,000 shares of Preferred Stock, par value $0.001 per share.
The following summary of certain provisions of the Common Stock and Preferred
Stock does not purport to be complete and is subject to, and qualified in its
entirety by, the provisions of the Company's Certificate of Incorporation, which
is included as an exhibit to the Registration Statement of which this Prospectus
is a part, and by the provisions of applicable law.
 
COMMON STOCK
 
   
     As of February 28, 1997, there were 22,720,234 shares of Common Stock
outstanding held of record by approximately 135 stockholders. The holders of
Common Stock are entitled to one vote per share on all matters to be voted on by
the stockholders. Subject to preferences that may be applicable to outstanding
shares of Preferred Stock, if any, the holders of Common Stock are entitled to
receive ratably such dividends as may be declared from time to time by the Board
of Directors out of funds legally available therefor. In the event of the
liquidation, dissolution or winding up of the Company, the holders of Common
Stock are entitled to share ratably in all assets remaining after payment of
liabilities, subject to prior liquidation rights of Preferred Stock, if any,
then outstanding. The Common Stock has no preemptive conversion rights or other
subscription rights. There are no redemption or sinking funds provisions
applicable to the Common Stock. All outstanding shares of Common Stock are fully
paid and non-assessable, and the shares of Common Stock to be outstanding upon
completion of the offering will be fully paid and non-assessable.
    
 
PREFERRED STOCK
 
     The Company is authorized to issue 5,000,000 shares of undesignated
Preferred Stock. The Board of Directors will have the authority to issue the
undesignated Preferred Stock in one or more series and to fix the rights,
preferences, privileges and restrictions granted to or imposed upon any wholly
unissued shares of undesignated Preferred Stock and to fix the number of shares
constituting any series in the designations of such series, without any further
vote or action by the stockholders. The Board of Directors, without stockholder
approval, can issue Preferred Stock with voting and conversion rights which
could adversely affect the voting power of the holders of Common Stock. The
issuance of Preferred Stock may have the effect of delaying, deferring or
preventing a change in control of the Company. The Company has no present plan
to issue Preferred Stock.
 
REGISTRATION RIGHTS
 
   
     Under the terms of the Registration Agreement dated as of May 28, 1996, as
amended (the "Registration Agreement"), the holders of approximately 4,779,000
shares of Common Stock (the "Registrable Securities") will be entitled to
certain rights with respect to the registration of such shares of Common Stock
under the Securities Act. Under the Registration Agreement, if at any time after
this offering the Company proposes to register any of its Common Stock under the
Securities Act, certain holders of Registrable Securities are entitled to notice
of such registration and to include their Registrable Securities therein;
provided, among other conditions, that the underwriters have the right to limit
the number of shares included in any such registration. Beginning six months
after the closing of the offering, the holders of at least fifty-five percent
(55%) of the Registrable Securities have the right to require the Company, on
not more than four occasions, to file a registration statement under the
Securities Act in order to register all or any part of their Registrable
Securities. The Company may, in certain circumstances, defer such registration
and the underwriters have the right, subject to certain limitations, to limit
the number of shares included in such registrations. Further, the holders of
Registrable Securities may require the Company to register all or any portion of
their Registrable Securities on Form S-3, when such form becomes available to
the Company, subject to certain conditions and limitations.

ANTI-TAKEOVER EFFECTS OF DELAWARE LAW
 
   
     The Company is subject to Section 203 of the Delaware Law ("Section 203").
Section 203 prohibits a publicly held Delaware corporation from engaging in a
"business combination" with an "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 approves either the business combination or the transaction that
resulted in the stockholder becoming an interested stockholder, (ii) upon
consummation of the transaction that resulted in the stockholder becoming an
interested stockholder, the interested stockholder owns at least 85% of the
outstanding voting stock, excluding certain shares held by employee directors
and employee stock plans, or (iii) on or after the consummation date the
business combination is approved by the board of directors and by the
affirmative vote of at least 66 2/3% of the outstanding voting stock that is not
owned by the interested stockholder. For purposes of Section 203, a "business
combination" includes, among other things, a merger, asset sale or other
transaction resulting in a financial benefit to the interested stockholder, and
an "interested stockholder" is generally a person who, together with affiliates
and associates, owns (or within three years, did own) 15% or more of the
corporation's voting stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to the offering, there has been no public market for securities of
the Company. No prediction can be made as to the effect, if any, that market
sales of shares or the availability of shares for sale will have on the market
price prevailing from time to time. Nevertheless, sales of substantial amounts
of Common Stock of the Company in the public market after the lapse of the
restrictions described below could adversely affect the prevailing market price
and the ability of the Company to raise equity capital in the future.
 
   
     Upon completion of the offering, the Company will have 26,720,234 shares of
Common Stock outstanding, assuming no exercise of outstanding options after
February 28, 1997. Of this amount, the 4,000,000 shares offered hereby will be
available for immediate sale in the public market as of the date of this
Prospectus. Approximately 1,087,000 additional shares will be available for sale
in the public market 90 days after the date of this Prospectus pursuant to Rule
701. However, approximately 213,000 of these shares will be subject to a right
of repurchase in favor of the Company in the event that the stockholder's
employment with the Company is terminated. Approximately 17,272,000 additional
shares will be available for sale in the public market following the expiration
of the 180-day lockup agreements with the Representatives of the Underwriters or
the Company, subject in some cases to compliance with the volume and other
limitations of Rule 144. However, approximately 642,000 of these shares will be
subject to a right of repurchase possessed by the Company. The remaining
approximately 4,361,000 shares held by existing stockholders will become
eligible for sale from time to time in the future under Rule 144.

     In general, under Rule 144 a person (or persons whose shares are
aggregated) who has beneficially owned shares for at least one year is entitled
to sell within any three-month period commencing 90 days after the date of this
Prospectus a number of shares that does not exceed the greater of (i) 1% of the
then outstanding shares of Common Stock (approximately 267,202 shares
immediately after the offering) or (ii) the average weekly trading volume during
the four calendar weeks preceding such sale, subject to the filing of a Form 144
with respect to such sale. A person (or persons whose shares are aggregated) who
is not deemed to have been an affiliate of the Company at any time during the 90
days immediately preceding the sale who has beneficially owned his or her shares
for at least two years is entitled to sell such shares pursuant to Rule 144(k)
without regard to the limitations described above. Persons deemed to be
affiliates must always sell pursuant to Rule 144, even after the applicable
holding periods have been satisfied.
    
 
     The Company is unable to estimate the number of shares that will be sold
under Rule 144, as this will depend on the market price for the Common Stock of
the Company, the personal circumstances of the sellers and other factors. Prior
to the offering, there has been no public market for the Common Stock, and there
can be no assurance that a significant public market for the Common Stock will
develop or be sustained after the offering. Any future sale of substantial
amounts of the Common Stock in the open market may adversely affect the market
price of the Common Stock offered hereby.
 
     The Company, its directors, executive officers, stockholders with
registration rights and certain other stockholders have agreed pursuant to the
Underwriting Agreement and other agreements that
 
                                       46
<PAGE>   48
 
   
they will not sell any Common Stock without the prior consent of Alex. Brown &
Sons Incorporated for a period of 180 days from the effective date of this
Prospectus, except that the Company may, without such consent, grant options and
sell shares pursuant to the 1996 Plan, the Director Plan and the Purchase Plan.
    
 
     The Company intends to file a registration statement on Form S-8 under the
Securities Act to register approximately 5,250,000 shares of Common Stock
subject to options outstanding or reserved for issuance under the 1996 Plan, the
Director Plan and the Purchase Plan within 90 days after the date of this
Prospectus, thus permitting the resale of such shares by nonaffiliates in the
public market without restriction under the Securities Act.
 
     Any employee or consultant to the Company who purchased his or her shares
pursuant to a written compensatory plan or contract is entitled to rely on the
resale provisions of Rule 701, which permits nonaffiliates to sell their Rule
701 shares without having to comply with the public information, holding period,
volume limitation or notice provisions of Rule 144 and permits affiliates to
sell their Rule 701 shares without having to comply with the Rule 144 holding
period restrictions, in each case commencing 90 days after the date of this
Prospectus.
 
   
     In addition, after the offering, the holders of approximately 4,779,000
shares of Common Stock will be entitled to certain rights with respect to
registration of such shares under the Securities Act. Registration of such
shares under the Securities Act would result in such shares becoming freely
tradeable without restriction under the Securities Act (except for shares
purchased by affiliates of the Company) immediately upon the effectiveness of
such registration. See "Description of Capital Stock -- Registration Rights."

</TABLE>
 
     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will purchase all shares of the Common Stock offered hereby if any
of such shares are purchased.
 
     The Company has been advised by the Representatives of the Underwriters
that the Underwriters propose to offer the shares of Common Stock to the public
at the initial public offering price set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession not in excess
of $          per share. The Underwriters may allow, and such dealers may
reallow, a concession not in excess of $          per share to certain other
dealers. After the initial public offering, the offering price and other selling
terms may be changed by the Representatives of the Underwriters.
 
   
     The Company has granted to the Underwriters an option, exercisable not
later than 30 days after the date of this Prospectus, to purchase up to 600,000
additional shares of Common Stock at the public offering price less the
underwriting discounts and commissions set forth on the cover page of this
Prospectus. To the extent that the Underwriters exercise such option, each of
the Underwriters will have a firm commitment to purchase approximately the same
percentage thereof that the number of shares of Common Stock to be purchased by
it shown in the above table bears to 4,000,000, and the Company will be
obligated, pursuant to the option, to sell such shares to the Underwriters. The
Underwriters may exercise such option only to cover over-allotments made in
connection with the sale of Common Stock offered hereby. If purchased, the
Underwriters will offer such additional shares on the same terms as those on
which the 4,000,000 shares are being offered.
    
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as amended.
 
   
     Stockholders of the Company, holding approximately 17,272,000 shares of
Common Stock, have agreed not to offer, sell or otherwise dispose of any of such
Common Stock for a period of 180 days after the effective date of this
Prospectus without the prior consent of Alex. Brown & Sons Incorporated (see
"Shares Eligible for Future Sale"), except that the Company may issue, and grant
options to purchase, shares of Common Stock under its current stock option and
purchase plans and other currently outstanding options.

     During and after the offering, the Underwriters may purchase and sell
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions and purchases to cover syndicate short positions
created in connection with the offering. The Underwriters also may impose
penalty bids, whereby selling concessions allowed to syndicate members or other
broker-dealers in respect of the Common Stock sold in the offering for their
account may be reclaimed by the syndicate if such securities are repurchased by
the syndicate in stabilizing or short-covering transactions. These activities
may stabilize, maintain or otherwise affect the market price of Common Stock,
which may be higher than the price that might otherwise prevail in the open
market. These transactions may be effected on the Nasdaq National Market or
otherwise and these activities, if commenced, may be discontinued at any time.
    
 
     The Representatives of the Underwriters have advised the Company that the
Underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.
 
   
     Prior to this offering, there has been no public market for the Common
Stock of the Company. Consequently, the initial public offering price for the
Common Stock will be determined by negotiation between the Company and the
Representatives of the Underwriters. Among the factors to be considered in such
negotiations will be prevailing market conditions, the results of operations of
the Company in recent periods, the market capitalizations, the price-earnings
ratios, the price-sales ratios, the market prices generally of securities and
stages of development of other companies that the Company and the
Representatives of the Underwriters believe to be comparable to the Company,
estimates of the business potential of the Company and its industry in general
and the present state of the Company's development and other factors deemed
relevant.
    
 
                                 LEGAL MATTERS
 
   
     The validity of the issuance of shares of Common Stock offered hereby will
be passed upon for the Company by Wilson Sonsini Goodrich & Rosati, P.C.
("WSG&R"), Palo Alto, California. Pillsbury Madison & Sutro LLP, Menlo Park,
California, is acting as counsel for the Underwriters in connection with certain
legal matters relating to the shares of Common Stock offered hereby. Jeffrey D.
Saper, a member of WSG&R, is Secretary and a director of the Company. Mr. Saper
owns 35,124 shares of Common Stock and 484 shares of Series A Redeemable
Preferred Stock. On February 25, 1997, Mr. Saper was granted an option to
purchase 25,000 shares of Common Stock pursuant to the Director Plan. As of the
date of this Prospectus, certain members of WSG&R, and investment partnerships
of which such persons are partners, beneficially own 140,922 shares of Common
Stock and 161 shares of Series A Redeemable Preferred Stock. A portion of the
proceeds from the offering will be used to redeem all of the outstanding Series
A Redeemable Preferred Stock. See "Use of Proceeds."
    
 
                                    EXPERTS
 
   
     The financial statements as of November 30, 1995 and 1996 and for each of
the three years in the period ended November 30, 1996 included in this
Prospectus and the related financial statement schedule included elsewhere in
the Registration Statement have been audited by Deloitte & Touche LLP,
independent auditors, as stated in their reports appearing herein and elsewhere
in the Registration Statement, and have been so included in reliance upon the
reports of such firm given upon their authority as experts in accounting and
auditing.
    
 
     In December 1996, the Company appointed Deloitte & Touche LLP to replace
KPMG Peat Marwick LLP as its principal accountants. There were no disagreements
with the former accountants during the preceding two fiscal years or during any
subsequent interim period preceding their replacement on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedures, which disagreements, if not resolved to the former
accountants' satisfaction, would have caused them to make reference to the
subject matter of the disagreement in
 
                                       49
<PAGE>   51
 
connection with their reports. KMPG Peat Marwick LLP issued an unqualified
opinion on the financial statements as of November 30, 1994 and 1995 and for the
three years in the period ended November 30, 1995. The Company did not consult
with Deloitte & Touche LLP on any accounting or financial reporting matters in
the two years prior to their appointment. The change in accountants was approved
by the Board of Directors.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of
  Aspec Technology, Inc.:
 
     We have audited the accompanying balance sheets of Aspec Technology, Inc.
as of November 30, 1995 and 1996, and the related statements of income,
stockholders' equity (deficiency) and cash flows for each of the three years in
the period ended November 30, 1996. 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, such financial statements present fairly, in all material
respects, the financial position of Aspec Technology, Inc. at November 30, 1995
and 1996, and the results of its operations and its cash flows for each of the
three years in the period ended November 30, 1996 in conformity with generally
accepted accounting principles.

             FEBRUARY 29, 1996 AND FEBRUARY 28, 1997 IS UNAUDITED)
    
 
1.  BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
   
     Business -- Aspec Technology, Inc. (the Company) develops, markets and
supports a commercial design implementation technology for use in the
semiconductor industry. The Company's primary customers are vertically
integrated semiconductor companies, fabless semiconductor companies, electronics
systems manufacturers and distributors that sell to such entities in Asia, North
America and Europe.
    
 
     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 revenues and expenses
during the reporting period. Actual results could differ from those estimates,
and such differences may be material to the financial statements.
 
     Cash Equivalents -- Cash equivalents consist of short-term highly liquid
debt investments with original maturities of 90 days or less.
 
   
     Accounts Receivable -- At November 30, 1996 and February 28, 1997, accounts
receivable included $121,000 and $732,000 of unbilled receivables, respectively
(none in 1995).
    
 
     Property and Equipment -- Property and equipment are stated at cost less
accumulated depreciation and amortization. Depreciation is provided using the
straight-line method over the estimated useful lives, generally three to five
years.
 
     Software Development Costs -- Development costs incurred in the research
and development of new software products and enhancements to existing software
products are expensed as incurred until technological feasibility has been
established, at which time certain development costs required to attain general
production release would be capitalized. To date, the Company's software
development has essentially been completed concurrent with the establishment of
technological feasibility, and, accordingly, no costs have been capitalized.
 
     Concentration of Credit Risk -- Financial instruments which potentially
subject the Company to concentrations of credit risk consist principally of cash
and equivalents and trade receivables. Cash equivalents consist primarily of
money market instruments carried at cost, which approximates fair market value.
Management believes the credit risk associated with such instruments is minimal.
The Company licenses its products to customers which are primarily designers and
manufacturers of integrated circuits. Management believes that risk of credit
loss is significantly reduced due to the diversity of its customers and their
dispersion across many geographic areas.
 
   
     Revenue Recognition -- A substantial majority of the Company's license
revenue has been recognized on a percentage of completion basis based upon
actual costs incurred since Aspec's products typically involve levels of
adaptation or completion. License terms typically include a payment upon
execution of the agreement with further payments upon completion of milestones.
Revenue is recognized ratably as the work is performed on the project. Billings
in excess of revenue are recorded as deferred revenue, while revenue in excess
of billings is recorded as unbilled receivables. Provisions for estimated losses
on uncompleted contracts are made in the period in which such losses are
determined. The time required to adapt a product for a specific customer
application generally ranges from three to twelve months. License revenue for
products not requiring adaptation is recognized upon delivery and when
collection is reasonably assured.

                             ASPEC TECHNOLOGY, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     Revenue from software support and maintenance contracts is deferred and
recognized ratably over the term of the agreement, which is typically one year.
Royalty revenues are earned and recognized in the period reported by the
customer or when cash is received.
    
 
     Income Taxes -- The Company accounts for income taxes using the asset and
liability method. Deferred tax assets and liabilities are recognized for the
future tax consequences of temporary differences between the financial statement
carrying amounts and the tax bases of assets and liabilities.
 
     Effects of Recent Accounting Standard -- In October 1995, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards
No. 123, Accounting for Stock-Based Compensation. The new standard defines a
fair value method of accounting for stock options and other equity instruments.
The new standard permits companies to continue to account for equity
transactions with employees under existing accounting rules, but requires
disclosure in a note to the financial statements of the pro forma net income and
income per share as if the Company had applied the new method of accounting.
Commencing in fiscal 1997, the Company intends to follow the disclosure
alternative for its employee stock compensation plans. Adoption of the new
standard will have no effect on the Company's financial position or results of
operations.
 
   
     Net Income Per Share -- Net income per share is based upon the weighted
average number of common and dilutive common equivalent shares (common stock
options, stock purchase rights and redeemable common stock) outstanding.
Pursuant to rules of the Securities and Exchange Commission (SEC), all common
shares issued and options and other rights granted to acquire shares of common
stock at a price less than the initial public offering price during the twelve
month period preceding the filing date (using the treasury stock method until
shares are issued) have been included in the computation of common and common
equivalent shares outstanding for all periods presented.
    
 
     For the purposes of the net income per share computation, net income has
been reduced by the amount of the periodic accretion for redeemable preferred
stock (see Note 6).
 
   
RECENTLY ISSUED ACCOUNTING STANDARD
    
 
   
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" (SFAS 128). The
Company is required to adopt SFAS 128 in the first quarter of fiscal 1998 and
will restate at that time earnings per share (EPS) data for prior periods to
conform with SFAS 128. Earlier application is not permitted.
    
 
   
     SFAS 128 replaces current EPS reporting requirements and requires a dual
presentation of basic and diluted EPS. Basic EPS excludes dilution and is
computed by dividing net income attributable to common stockholders by the
weighted average of common shares outstanding for the period. Diluted EPS
reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock.
However, the SEC rules regarding share issuances and option and other rights
granted to acquire shares prior to an initial public offering, as stated above,
are still applicable and such amounts are included in both basic and diluted
EPS.

     Unaudited Interim Financial Information -- The unaudited interim financial
information as of February 28, 1997 and for the three months ended February 28,
1997 and 1996 has been prepared on the same basis as the audited financial
statements. In the opinion of management, such unaudited information includes
all adjustments (consisting only of normal recurring accruals) necessary for a
fair presentation of this interim information. Operating results of the three
months ended February 28, 1997 are not necessarily indicative of the results
that may be expected for any future period.
    
 
   
     Unaudited Pro Forma Information -- Upon the closing of the initial public
offering contemplated by this Prospectus, the redemption privileges of the
redeemable common stock will terminate. The pro forma amounts in the
accompanying balance sheet present the Company's stockholders' equity as if all
such redemption privileges had terminated as of February 28, 1996.

6.  REDEEMABLE STOCK
 
     Redeemable Preferred Stock
 
     During 1996, the Board of Directors authorized and designated 130,385
shares of Series A redeemable preferred stock. In May and June 1996, the Company
sold an aggregate of 130,378 shares of Series A redeemable preferred stock at
$100 per share, resulting in net proceeds of approximately $12,953,000. The
significant terms of the Series A redeemable preferred stock are as follows:
 
     - In the event of liquidation, dissolution or winding up of the Company,
       the redeemable preferred stockholders shall receive, per share, the
       greater of (1) the initial issue price ($100) plus all accrued but unpaid
       dividends or (2) $141.86, prior to any distribution to be made to holders
       of the Company's common stock.
 
     - Dividends shall accrue on a daily basis at the rate of 6% per annum on
       the sum of the liquidation value plus all accrued but unpaid dividends.
 
     - The redeemable preferred shares have no voting rights except that:
 
   
          - The Series A preferred stockholders, voting as a class, shall be
            entitled to elect two directors as long as the holders of record on
            June 30, 1996 continue to hold 50% or more of the Series A preferred
            shares (or to elect one director if the holders of record on June
            30, 1996 continue to hold 25% to 50% of the Series A preferred
            shares).
    
 
          - So long as any Series A preferred shares remain outstanding, the
            corporation shall not, without a vote of 55% of the outstanding
            Series A preferred shares, issue securities with equity features
            senior to Series A preferred stock, liquidate, change the Series A
            preferred rights or merge or consolidate with another entity which
            results in the Company's common stockholders immediately prior to
            the transaction owning less than 66.7% of the common stock after the
            transaction.

     - The redeemable preferred shares are not convertible into common stock.
 
     - The Company is obligated to redeem the corresponding percentage of
       preferred shares on the following dates:

        June 1, 2003..................................................................   100%
</TABLE>
 
     - In the event of an initial public offering (IPO), the Company shall apply
       the net proceeds of the offering, less $20 million to be retained by the
       Company, to the redemption of the Series A redeemable preferred shares at
       the redemption value, which is, on a per share basis, greater of (1) the
       original issue price plus all accrued but unpaid dividends or (2)
       $141.86. In the event of a change in ownership prior to an IPO, the
       Company shall redeem the Series A preferred stock at the redemption
       value. The aggregate liquidation and redemption value as of November 30,
       1996 was approximately $18,495,000. The Company is accreting the
       difference between the book value of the preferred stock and its
       redemption value over the period from the issuance date through the
       mandatory redemption dates. In the event of an IPO resulting in a
       redemption, the difference between the book value and the redemption
       value will be considered as additional accretion for preferred stock in
       the quarter of the IPO when determining income attributable to common
       stockholders and earnings per share.
 
     Redeemable Common Stock
 
     During May and June 1996, the Company sold an aggregate of 4,778,804 shares
of redeemable common stock to the preferred stock investors for net proceeds of
approximately $7,116,000. Under a stockholder rights agreement, these investors
have a put option, exercisable at any time after the seventh anniversary of the
agreement, to require the Company to repurchase for cash all of the common
shares held by such investors at a price determined based upon the then market
value of the Company divided by the number of common shares outstanding. This
right terminates upon an IPO. The holders of these shares have certain
registration rights.
 
7.  STOCKHOLDERS' EQUITY
 
     Repurchase of Common Stock
 
     During August 1996, the Company repurchased an aggregate of 4,778,786
shares of common stock held by certain founders of the Company at $4.227 per
share for an aggregate purchase price of approximately $20,200,000.
 
     Employee Stock Plans
 
   
     Under the 1992 Employee Stock Purchase Plan (the 1992 Plan), 4,000,000
shares of the Company's common stock were reserved and available for issuance to
officers, directors, employees and consultants of the Company. The 1992 Plan
provides that the purchase or exercise price of the stock covered by the Plan
shall be no less than the fair value of the Company's common stock at the date
of the grant, as determined by the Board of Directors. The Board of Directors
also has the authority to set exercise dates (generally no longer than ten years
from the date of grant), payment terms and other provisions for each grant.
Stock purchase rights and options granted under the plan generally vest as to
25% of the shares on the first anniversary of the date of grant and thereafter
vest ratably over three years. The Company has the option to repurchase
exercised shares that have not vested at the original purchase price upon
termination of employment. As of November 30, 1996, there were no stock purchase
rights outstanding under the 1992 Plan and in December 1996, the

Company's Board of Directors determined not to grant or issue any additional
shares under the 1992 Plan.
 
   
     In 1996, the Board of Directors adopted the 1996 Stock Option Plan (the
1996 Plan). Under this plan, 2,000,000 shares (4,500,000 shares as amended in
February 1997) have been reserved for issuance to directors, officers, employees
and consultants to the Company at prices not less than the fair market value for
incentive options. These options generally expire five to ten years from the
date of grant. Incentive and nonstatutory options normally vest and become
exercisable at an annual rate of 25%.
    
 
   
     In February 1997, the Board of Directors adopted the 1997 Director Option
Plan and reserved 250,000 shares of common stock for grants of options to each
outside director. The Director Plan provides for the automatic grant to outside
directors of an option to purchase 25,000 shares of Common Stock at the time the
director joins the board and an option to purchase 5,000 shares of Common Stock
upon the outside director's annual reelection to the Board.

plans, along with 650,000 shares issued outside of the Plan in fiscal 1996, is

     At November 30, 1996 and February 28, 1997, the weighted average exercise
price of options outstanding was $4.05 and $6.01, respectively, and
approximately 1,446,000 and 3,383,000 shares, respectively, were available for
future grant under the 1996 Plan. At February 28, 1997, 225,000 shares were
available for future grant under the 1997 Director Option Plan. As of November
30, 1996 and February 28, 1997, approximately 1,240,000 and 1,144,000 shares,
respectively, exercised and outstanding under the 1992 Plan were subject to
repurchase by the Company at the original purchase price.
    
 
     In connection with certain issuances of stock purchase rights or options
under the Plans, the Company recorded stock compensation for the difference
between the deemed fair value for accounting purposes and the issuance or
exercise price. Such amounts are amortized to expense over the related vesting
periods.
 
   
     Recently Issued Accounting Standard -- In October 1995, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards
No. 123, "Accounting for Stock-Based Compensation." The new standard defines a
fair value method of accounting for stock options and

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
   
other equity instruments, such as stock purchase plans. Under this method,
compensation cost is measured based on the fair value of the stock award when
granted and is recognized as an expense over the service period, which is
usually the vesting period. This standard is effective for the Company beginning
in fiscal 1997 and requires measurement of awards made beginning in fiscal 1996.
    
 
   
     The new standard permits companies to continue to account for equity
transactions with employees under existing accounting rules, but requires
disclosure in a note to the financial statements of the pro forma net income and
earnings per share as if the Company had applied the new method of accounting.
The Company intends to implement these disclosure requirements for its employee
stock plans beginning with its annual financial statements for the year ending
November 30, 1997. Based on the Company's current use of equity instruments,
adoption of the new standard will not impact reported net income per share, and
will have no effect on the Company's cash flows.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law (the "Delaware Law")
authorizes a court to award, or a corporation's Board of Directors to grant,
indemnity to directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). Article Ten of the Registrant's Certificate
of Incorporation (Exhibit 3.1 hereto) and Article VI of the Registrant's Bylaws
(Exhibit 3.3 hereto) provide for indemnification of the Registrant's directors,
officers, employees and other agents to the maximum extent permitted by Delaware
Law. In addition, the Registrant has entered into Indemnification Agreements
(Exhibit 10.1 hereto) with its officers and directors. The Underwriting
Agreement (Exhibit 1.1) also provides for cross-indemnification among the
Company and the Underwriters with respect to certain matters, including matters
arising under the Securities Act.

ITEM 17.  UNDERTAKINGS
 
     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 referenced in Item 14 of this Registration
Statement or otherwise, the Registrant has been advised that in the opinion of
the Commission such indemnification is against public policy as expressed in the
Securities Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the
 
                                      II-3
<PAGE>   70
 
question of whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
     The undersigned 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 a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
 
     The undersigned 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.

ALEX. BROWN & SONS INCORPORATED
HAMBRECHT & QUIST LLC
WESSELS, ARNOLD & HENDERSON, L.L.C.
As Representatives of the
      Several Underwriters
c/o Alex. Brown & Sons Incorporated
135 East Baltimore Street
Baltimore, Maryland 21202

Gentlemen:

      Aspec Technology, Inc., a Delaware corporation (the "Company@), proposes
to sell to the several underwriters (the "Underwriters") named in Schedule I
hereto for whom you are acting as representatives (the "Representatives") an
aggregate of 4,000,000 shares of the Company's Common Stock, $0.001 par value
(the "Firm Shares").  The respective amounts of the Firm Shares to be so
purchased by the several Underwriters are set forth opposite their names in
Schedule I hereto.  The Company also proposes to sell at the Underwriters'
option an aggregate of up to 600,000 additional shares of the Company's Common
Stock (the "Option Shares") as set forth below.

      As the Representatives, you have advised the Company (a) that you are
authorized to enter into this Agreement on behalf of the several Underwriters,
and (b) that the several Underwriters are willing, acting severally and not
jointly, to purchase the numbers of Firm Shares set forth opposite their
respective names in Schedule I, plus their pro rata portion of the Option
Shares if you elect to exercise the overallotment option in whole or in part
for the accounts of the several Underwriters.  The Firm Shares and the Option
Shares (to the extent the aforementioned option is exercised) are herein
collectively called the "Shares."

      In consideration of the mutual agreements contained herein and of the
interests of the parties in the transactions contemplated hereby, the parties
hereto agree as follows:
<PAGE>   2
      1.      REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

              The Company represents and warrants to each of the Underwriters
      as follows:

              (a)  A registration statement on Form S-1 (File No. 333-22913)
      with respect to the Shares has been prepared by the Company in conformity
      with the requirements of the Securities Act of 1933, as amended (the
      "Act"), and the Rules and Regulations (the "Rules and Regulations") of
      the Securities and Exchange Commission (the "Commission") thereunder and
      has been filed with the Commission. Copies of such registration
      statement, including any amendments thereto, the preliminary prospectuses
      (meeting the requirements of the Rules and Regulations) contained therein
      and the exhibits, financial statements and schedules, as finally amended
      and revised, have heretofore been delivered by the Company to you.  Such
      registration statement, together with any registration statement filed by
      the Company pursuant to Rule 462 (b) of the Act, herein referred to as
      the "Registration Statement," which shall be deemed to include all
      information omitted therefrom in reliance upon Rule 430A and contained in
      the Prospectus referred to below, has become effective under the Act and
      no post-effective amendment to the Registration Statement has been filed
      as of the date of this Agreement.  "Prospectus" means (a) the  form of
      prospectus first filed with the Commission pursuant to Rule 424(b) or (b)
      the last preliminary prospectus included in the Registration Statement
      filed prior to the time it becomes effective or filed pursuant to Rule
      424(a) under the Act that is delivered by the Company to the Underwriters
      for delivery to purchasers of the Shares, together with the term sheet or
      abbreviated term sheet filed with the Commission pursuant to Rule
      424(b)(7) under the Act.  Each preliminary prospectus included in the
      Registration Statement prior to the time it becomes effective is herein
      referred to as a "Preliminary Prospectus."  Any reference herein to the
      Registration Statement, any Preliminary Prospectus or to the Prospectus
      shall be deemed to refer to and include any supplements or amendments to
      any Prospectus filed with the Commission after the date of filing of the
      Prospectus under Rules 424(b) or 430A, and prior to the termination of
      the offering of the Shares by the Underwriters.

              (b)  The Company has been duly organized and is validly existing
      as a corporation in good standing under the laws of the State of
      Delaware, with corporate power and authority to own or lease its
      properties and conduct its business as described in the Registration
      Statement.  The Company is duly qualified to transact business in all
      jurisdictions in which the conduct of its business requires such
      qualification except where the failure to be so qualified would not have
      a material adverse effect on the business or financial condition of the
      Company.

              (c)  The outstanding shares of Common Stock of the Company have
      been duly authorized and validly issued and are fully paid and
      non-assessable; the Shares to be issued and sold by the Company have been
      duly authorized and when issued and paid for as contemplated herein will
      be validly issued, fully paid and non-assessable; and no preemptive
      rights of stockholders exist with respect to any of the Shares or the
      issue and





                                       2
<PAGE>   3
      sale thereof.  Neither the filing of the Registration Statement nor the
      offering or sale of the Shares as contemplated by this Agreement gives
      rise to any rights, other than those which have been waived or satisfied,
      for or relating to the registration of any shares of Common Stock.

              (d)  The information set forth under the caption "Capitalization"
      in the Prospectus is true and correct as of the date set forth therein
      and under the stated assumptions.  All of the Shares conform in all
      material respects to the description thereof contained in the
      Registration Statement.  The  form of certificates for the Shares
      conforms in all material respects to the corporate law of the
      jurisdiction of the Company's incorporation.

              (e)  The Commission has not issued an order preventing or
      suspending the use of any Prospectus relating to the proposed offering of
      the Shares nor instituted proceedings for that purpose.  The Registration
      Statement contains, and the Prospectus and any amendments or supplements
      thereto will contain, all statements which are required to be stated
      therein by, and will conform in all material respects, to the
      requirements of the Act and the Rules and Regulations.  The Registration
      Statement and any amendment thereto do not contain, and will not through
      the Closing Date and, if later, the Option Closing Date (as such date is
      hereinafter defined) contain, any untrue statement of a material fact and
      do not omit, and will not through the Closing Date and, if later, the
      Option Closing Date (as such date is hereinafter defined) omit, to state
      any material fact required to be stated therein or necessary to make the
      statements therein not misleading.  The Prospectus and any amendments and
      supplements thereto do not contain, and will not through the Closing Date
      and, if later, the Option Closing Date (as such date is hereinafter
      defined) contain, any untrue statement of material fact; and do not omit,
      and will not through the Closing Date and, if later, the Option Closing
      Date (as such date is hereinafter defined) omit, to state any material
      fact required to be stated therein or necessary to make the statements
      therein, in the light of the circumstances under which they were made,
      not misleading; provided, however, that the Company makes no
      representations or warranties as to information contained in or omitted
      from the Registration Statement or the Prospectus, or any such amendment
      or supplement, in reliance upon, and in conformity with, written
      information furnished to the Company by or on behalf of any Underwriter
      through the Representatives, specifically for use in the preparation
      thereof.

              (f)  The financial statements of the Company, together with
      related notes and schedules as set forth in the Registration Statement,
      present fairly in all material respects the financial position and the
      results of operations and cash flows of the Company, at the indicated
      dates and for the indicated periods.  Such financial statements and
      related schedules have been prepared in accordance with generally
      accepted principles of accounting, consistently applied throughout the
      periods involved, except as disclosed herein, and all adjustments
      necessary for a fair presentation of results for such periods have been
      made.  The summary financial and statistical data included in the
      Registration Statement presents fairly in all material respects the
      information shown therein and such





                                       3
<PAGE>   4
      data has been compiled on a basis consistent with the financial
      statements presented therein and the books and records of the Company.

              (g)  Deloitte & Touche LLP, who have certified certain of the
      financial statements filed with the Commission as part of the
      Registration Statement, are independent public accountants as required by
      the Act and the Rules and Regulations.

              (h)  There is no action, suit, claim or proceeding pending or, to
      the knowledge of the Company, threatened against the Company before any
      court or administrative agency or otherwise which if determined adversely
      to the Company might result in any material adverse change in the
      earnings, business,  management, properties, assets, rights, operations,
      financial condition of the Company or to prevent the consummation of the
      transactions contemplated hereby, except as set forth in the Registration
      Statement.

              (i)  The Company has good and marketable title to all of the
      properties and assets reflected in the financial statements (or as
      described in the Registration Statement) hereinabove described, subject
      to no lien, mortgage, pledge, charge or encumbrance of any kind except
      those reflected in such financial statements (or as described in the
      Registration Statement) or which are not material in amount.  The Company
      occupies its leased properties under a valid and binding lease filed as
      Exhibit 10.6 to the Registration Statement.

              (j)  The Company has filed all Federal, State, local and foreign
      income tax returns which have been required to be filed and have paid all
      taxes indicated by said returns and all assessments received by them or
      any of them to the extent that such taxes have become due.  All tax
      liabilities have been adequately provided for in the financial statements
      of the Company.

              (k)  Since the respective dates as of which information is given
      in the Registration Statement, as it may be amended or supplemented,
      there has not been any material adverse change or any development
      involving a prospective material adverse change in or affecting the
      business operations or financial condition of the Company, whether or not
      occurring in the ordinary course of business, and there has not been any
      material transaction entered into or any material transaction that is
      probable of being entered into by the Company, other than transactions in
      the ordinary course of business and changes and transactions described in
      the Registration Statement, as it may be amended or supplemented.  The
      Company has no material contingent obligations which are not disclosed in
      the Company's financial statements which are included in the Registration
      Statement.

              (l)  The Company is not, nor with the giving of notice or lapse
      of time or both, will be, in violation of or in default under its Charter
      or Bylaws or under any agreement, lease, contract, indenture or other
      instrument or obligation to which it is a party or by which it, or any of
      its properties, is bound and which default is of material significance in
      respect of the business, management, properties, assets, rights,
      operations or financial





                                       4
<PAGE>   5
      condition of the Company.  The execution and delivery of this Agreement
      and the consummation of the transactions herein contemplated and the
      fulfillment of the terms hereof will not conflict with or result in a
      breach of any of the terms or provisions of, or constitute a default
      under, any indenture, mortgage, deed of trust or other agreement or
      instrument to which the Company is a party, or of the Charter or bylaws
      of the Company or any order, rule or regulation applicable to the Company
      of any court or of any regulatory body or administrative agency or other
      governmental body having jurisdiction, except where such conflict, breach,
      violation or default would not have a material adverse effect on business
      or financial condition of the Company.

              (m)  Each approval, consent, order, authorization, designation,
      declaration or filing by or with any regulatory, administrative or other
      governmental body necessary in connection with the execution and delivery
      by the Company of this Agreement and the consummation of the transactions
      herein contemplated (except such additional steps as may be required by
      the Commission, the National Association of Securities Dealers, Inc. (the
      "NASD") or such additional steps as may be necessary to qualify the
      Shares for public offering by the Underwriters under state securities or
      Blue Sky laws) has been obtained or made and is in full force and effect.

              (n)  The Company holds all material licenses, certificates and
      permits from governmental authorities which are necessary to the conduct
      of its business; and, to the Company's knowledge, the Company has not
      infringed any patents, patent rights, trade names, trademarks or
      copyrights, which infringement is material to the business of the
      Company.  The Company has no actual knowledge of any infringement by
      others of patents, patent rights, trade names, trademarks or copyrights
      owned by or licensed to the Company which infringement is material to the
      business of the Company.

              (o)  Neither the Company, nor to the Company's best knowledge,
      any of its affiliates, has taken or may take, directly or indirectly, any
      action designed to cause or result in, or which has constituted or which
      might reasonably be expected to constitute, the stabilization or
      manipulation of the price of the shares of Common Stock to facilitate the
      sale or resale of the Shares.

              (p)  The Company is not an "investment company" within the
      meaning of such term under the Investment Company Act of 1940 and the
      rules and regulations of the Commission thereunder.

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





                                       5

              (r)  The Company carries, or is covered by, insurance in such
      amounts and of the types generally deemed adequate for the conduct of its
      business and the value of its respective properties and as is consistent
      with insurance maintained by companies engaged in similar industries.

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

              (t)  The Company confirms as of the date hereof that it is in
      compliance with all provisions of  Section 517.075 of Laws of Florida,
      Chapter 92-198, An Act Relating to Disclosure of doing Business with
      Cuba.

              [(u)  The Company (i) is in compliance with any and all
      applicable foreign, federal, state and local laws and regulations
      relating to the protection of human health and safety, the environment or
      imposing liability or standards of conduct concerning any Hazardous
      Material (as hereinafter defined) ("Environmental Laws"), (ii) has
      received all permits, licenses or other approvals required of it under
      applicable Environmental Laws to conduct its business and (iii) is in
      compliance with all terms and conditions of any such permit, license or
      approval, except where such noncompliance with Environmental Laws,
      failure to receive required permits, licenses or other approvals or
      failure to comply with the terms and conditions of such permits, licenses
      or approvals would not, individually or in the aggregate, result in a
      material adverse effect on the financial condition or on the earnings,
      business, properties, business prospects or operations of the Company.
      The term "Hazardous Material" means (1) any "hazardous substance" as
      defined by the Comprehensive Environmental Response, Compensation and
      Liability Act of 1980, as amended, (2) any "hazardous waste" as defined
      by the Resource Conservation and Recovery Act, as amended, (3) any
      petroleum or petroleum product, (4) any polychlorinated biphenyl and (5)
      any pollutant or contaminant or hazardous, dangerous, or toxic chemical,

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

              (a)  On the basis of the representations, warranties and
      covenants herein contained, and subject to the conditions herein set
      forth, the Company agrees to sell to the Underwriters and each
      Underwriter agrees, severally and not jointly, to purchase, at a price of
      $_____ per share, the number of Firm Shares set forth opposite the name
      of each Underwriter in Schedule I hereof, subject to adjustments in
      accordance with Section 9 hereof.

              (b)  Payment for the Firm Shares to be sold hereunder is to be
      made in same-day funds by wire transfer to the order of the Company
      against delivery of certificates therefor to the Representatives for the
      several accounts of the Underwriters.  Such payment and delivery are to
      be made at the offices of Alex. Brown & Sons Incorporated, 135 East
      Baltimore Street, Baltimore, Maryland, at 10:00 a.m., Baltimore time, on
      the third business day after the date of this Agreement or at such other
      time and date not later than five business days thereafter as you and the
      Company shall agree upon, such time and date being herein referred to as
      the "Closing Date." (As used herein, "business day" means a day on which
      the New York Stock Exchange is open for trading and on which banks in New
      York are open for business and are not permitted by law or executive
      order to be closed.)  The certificates for the Firm Shares will be
      delivered in such denominations and in such registrations as the
      Representatives request in writing not later than the second full
      business day prior to the Closing Date, and will be made available for
      inspection by the Representatives at least one business day prior to the
      Closing Date.

              (c)  In addition, on the basis of the representations and
      warranties herein contained and subject to the terms and conditions
      herein set forth, the Company hereby grants an option to the several
      Underwriters to purchase the Option Shares at the price per share as set
      forth in the first paragraph of this Section 2.  The option granted
      hereby may be exercised in whole or in part by giving written notice (i)
      at any time before the Closing Date and (ii) only once thereafter within
      30 days after the date of this Agreement, by you, as Representatives of
      the several Underwriters, to the Company setting forth the number of
      Option Shares as to which the several Underwriters are exercising the
      option, the names and denominations in which the Option Shares are to be
      registered and the time and date at which such certificates are to be
      delivered.  The time and date at which certificates for Option Shares are
      to be delivered shall be determined by the Representatives but shall not
      be earlier than three nor later than 10 full business days after the
      exercise of such option, nor in any event prior to the Closing Date (such
      time and date being herein referred to as the "Option Closing Date").  If
      the date of exercise of the option is three or more days before the
      Closing Date, the notice of exercise shall set the Closing Date as the
      Option Closing Date.  The number of Option Shares to be purchased by each
      Underwriter shall be in the same proportion to the total number of Option
      Shares being purchased as the number of Firm Shares being purchased by
      such Underwriter bears to the total number of Firm Shares, adjusted by
      you in such manner as to avoid fractional shares.  The option with
      respect to the Option Shares granted hereunder may be exercised only to
      cover over-allotments in the sale of the Firm Shares





                                       7
<PAGE>   8
      by the Underwriters.  You, as Representatives of the several
      Underwriters, may cancel such option at any time prior to its expiration
      by giving written notice of such cancellation to the Company.  To the
      extent, if any, that the option is exercised, payment for the Option
      Shares shall be made on the Option Closing Date by wire transfers in
      same-day funds to the order of the Company against delivery of
      certificates therefor at the offices of Alex. Brown & Sons Incorporated,
      135 East Baltimore Street, Baltimore, Maryland.

      3.      OFFERING BY THE UNDERWRITERS.

              It is understood that the several Underwriters are to make a
      public offering of the Firm Shares as soon as the Representatives deem it
      advisable to do so.  The Firm Shares are to be initially offered to the
      public at the initial public offering price set forth in the Prospectus.
      The Representatives may from time to time thereafter change the public
      offering price and other selling terms.  To the extent, if at all, that
      any Option Shares are purchased pursuant to Section 2 hereof, the
      Underwriters will offer them to the public on the foregoing terms.

              It is further understood that you will act as the Representatives
      for the Underwriters in the offering and sale of the Shares in accordance
      with a Master Agreement Among Underwriters entered into by you and the
      several other Underwriters.

      4.      COVENANTS OF THE COMPANY.

              The Company covenants and agrees with the several Underwriters
      that:

              (a)  The Company will (A) use its reasonable best efforts to
      cause the Registration Statement to become effective, if not effective at
      the time and date that this Agreement is executed and delivered by the
      parties hereto, or, if the procedure in Rule 430A of the Rules and
      Regulations is followed, to prepare and timely file with the Commission
      under Rule 424(b) of the Rules and Regulations a Prospectus in a form
      approved by the Representatives containing information previously omitted
      at the time of effectiveness of the Registration Statement in reliance on
      Rule 430A of the Rules and Regulations, (B) not file any amendment to the
      Registration Statement or supplement to the Prospectus of which the
      Representatives shall not previously have been advised and furnished with
      a copy or to which the Representatives shall have reasonably objected in
      writing or which is not in compliance with the Rules and Regulations and
      (C) file on a timely basis all reports and any definitive proxy or
      information statements required to be filed by the Company with the
      Commission subsequent to the date of the Prospectus and prior to the
      termination of the offering of the Shares by the Underwriters.

              (b)  The Company will advise the Representatives promptly (A)
      when the Registration Statement or any post-effective amendment thereto
      shall have become effective, (B) of receipt of any comments from the
      Commission, (C) of any request of the Commission for amendment of the
      Registration Statement or for supplement to the





                                       8
<PAGE>   9
      Prospectus or for any additional information, and (D) of the issuance by
      the Commission of any stop order suspending the effectiveness of the
      Registration Statement or the use of the Prospectus or of the institution
      of any proceedings for that purpose.  The Company will use its reasonable
      best efforts to prevent the issuance of any such stop order preventing or
      suspending the use of the Prospectus and to obtain as soon as possible
      the lifting thereof, if issued.

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

              (d)  The Company will deliver to, or upon the order of, the
      Representatives, from time to time, as many copies of any Preliminary
      Prospectus as the Representatives may reasonably request.  The Company
      will deliver to, or upon the order of, the Representatives during the
      period when delivery of a Prospectus is required under the Act, as many
      copies of the Prospectus in final form, or as thereafter amended or
      supplemented, as the Representatives may reasonably request.  The Company
      will deliver to the Representatives at or before the Closing Date, four
      signed copies of the Registration Statement and all amendments thereto
      including all exhibits filed therewith, and will deliver to the
      Representatives such number of copies of the Registration Statement
      (including such number of copies of the exhibits filed therewith that may
      reasonably be requested), and of all amendments thereto, as the
      Representatives may reasonably request.

              (e)  The Company will comply with the Act and the Rules and
      Regulations, and the Securities Exchange Act of 1934, as amended (the
      "Exchange Act"), and the rules and regulations of the Commission
      thereunder, so as to permit the completion of the distribution of the
      Shares as contemplated in this Agreement and the Prospectus.  If during
      the period in which a prospectus is required by law to be delivered by an
      Underwriter or dealer, any event shall occur as a result of which, in the
      judgment of the Company or in the reasonable opinion of the Underwriters,
      it becomes necessary to amend or supplement the Prospectus in order to
      make the statements therein, in the light of the circumstances existing
      at the time the Prospectus is delivered to a purchaser, not misleading,
      or, if it is necessary at any time to amend or supplement the Prospectus
      to comply with any law, the Company promptly will prepare and file with
      the Commission an appropriate amendment to the Registration Statement or
      supplement to the Prospectus so that the Prospectus as so amended or
      supplemented will not, in the light of the





                                       9
<PAGE>   10
      circumstances when it is so delivered, be misleading, or so that the
      Prospectus will comply with the law.

               (f)  Unless this requirement is otherwise satisfied, the Company
      will make generally available to its security holders, as soon as it is
      practicable to do so, but in any event not later than 16-1/2 months after
      the effective date of the Registration Statement, an earning statement
      (which need not be audited) in reasonable detail, covering a period of at
      least 12 consecutive months beginning after the effective date of the
      Registration Statement, which earning statement shall satisfy the
      requirements of Section 11(a) of the Act and Rule 158 of the Rules and
      Regulations and will advise you in writing when such statement has been
      so made available.

              (g)  The Company will, for a period of five years from the
      Closing Date, deliver to the Representatives copies of annual reports and
      copies of all other documents, reports and information furnished by the
      Company to its stockholders or filed with any securities exchange
      pursuant to the requirements of such exchange or with the Commission
      pursuant to the Act or the Exchange Act.  The Company will deliver to the
      Representatives similar reports with respect to significant subsidiaries,
      as that term is defined in the Rules and Regulations, which are not
      consolidated in the Company's financial statements.

              (h)  No offering, sale, short sale or other disposition of any
      shares of Common Stock of the Company or other securities convertible
      into or exchangeable or exercisable for shares of  Common Stock or
      derivative of Common Stock  (or agreement for such) will be made for a
      period of 180 days after the date of this Agreement, directly or
      indirectly, by the Company otherwise than (i) hereunder, (ii) with the
      prior written consent of Alex. Brown & Sons Incorporated, (iii) pursuant
      to the stock option or stock purchase plans of the Company which are
      described in the Registration Statement and the Prospectus or (iv) by
      the Company pursuant to a merger or acquisition; provided, however, that
      the recipients of any securities of the Company pursuant to any such
      merger or acquisition either agree to be bound by a lockup agreement
      substantially similar to the letters to be provided to the
      Representatives at the Closing pursuant to paragraph (j) below or will
      not, pursuant to the terms of the acquisition transaction, be able to
      make a public sale of Common Shares during such 180-day period.

              (i)  The Company will use its reasonable best efforts to list,
      subject to notice of issuance, the Shares on The Nasdaq National Market.

              (j)  The Company has caused each officer and director and
      specific stockholders of the Company to furnish to you, on or prior to
      the date of this agreement, a letter or letters, in form and substance
      satisfactory to the Underwriters, pursuant to which each such person
      shall agree not to offer, sell, sell short or otherwise dispose of any
      shares of Common Stock of the Company or other capital stock of the
      Company, or any other securities convertible, exchangeable or exercisable
      for Common Shares or derivative of Common Shares owned by such person or
      request the registration for the offer or sale of





                                       10
<PAGE>   11
      any of the foregoing  (or as to which such person has the right to direct
      the disposition of) for a period of 180 days after the date of this
      Agreement, directly or indirectly, except with the prior written consent
      of Alex. Brown & Sons Incorporated ("Lockup Agreements").

              (k)  The Company shall apply the net proceeds of its sale of the
      Shares as set forth in the Prospectus and shall file such reports with
      the Commission with respect to the sale of the Shares and the application
      of the proceeds therefrom as may be required in accordance with Rule 463
      under the Act.

              (l)  The Company shall not invest, or otherwise use the proceeds
      received by the Company from its sale of the Shares in such a manner as
      would require the Company to register as an investment company under the
      Investment Company Act of 1940, as amended (the "1940 Act").

              (m)  The Company will maintain a transfer agent and, if necessary
      under the jurisdiction of incorporation of the Company, a registrar for
      the Common Stock.

              (n)  The Company will not take, directly or indirectly, any
      action designed to cause or result in, or that has constituted or might
      reasonably be expected to constitute, the stabilization or manipulation
      of the price of any securities of the Company.

      5.      COSTS AND EXPENSES.

              The Company will pay all costs, expenses and fees incident to the
      performance of the obligations of the Company under this Agreement,
      including, without limiting the generality of the foregoing, the
      following:  accounting fees of the Company; the fees and disbursements of
      counsel for the Company; the cost of printing and delivering to, or as
      requested by, the Underwriters copies of the Registration Statement,
      Preliminary Prospectuses, the Prospectus, this Agreement, the
      Underwriters' Selling Memorandum, the Underwriters' Invitation Letter,
      the Listing Application, the Blue Sky Survey and any supplements or
      amendments thereto; the filing fees of the Commission; the filing fees
      incident to securing any required review by the National Association of
      Securities Dealers, Inc. (the "NASD") of the terms of the sale of the
      Shares; the Listing Fee of The Nasdaq National Market; and the expenses,
      including the fees and disbursements of counsel for the Underwriters,
      incurred in connection with the qualification of the Shares under State
      securities or Blue Sky laws.  The Company shall not, however, be required
      to pay for any of the Underwriters expenses (other than those related to
      qualification under NASD regulation and State securities or Blue Sky
      laws) except that, if this Agreement shall not be consummated because the
      conditions in Section 6 (other than paragraph (c)) hereof are not
      satisfied, or because this Agreement is terminated by the Representatives
      pursuant to Section 11[(b)(i), (vi) or (vii)] hereof, or by reason of any
      failure, refusal or inability on the part of the Company to perform any
      undertaking or satisfy any condition of this Agreement or to comply with
      any of the terms hereof on its part to be performed, unless such failure
      to satisfy said condition or to comply with said





                                       11
<PAGE>   12
      terms be due to the default or omission of any Underwriter, then the
      Company shall reimburse the several Underwriters for reasonable
      out-of-pocket expenses, including fees and disbursements of counsel,
      reasonably incurred in connection with investigating, marketing and
      proposing to market the Shares or in contemplation of performing their
      obligations hereunder; but the Company shall not in any event be liable
      to any of the several Underwriters for damages on account of loss of
      anticipated profits from the sale by them of the Shares.  Except as
      specifically identified in this Section 5, the Company shall not be
      responsible for fees of counsel to the Underwriters in connection with
      the transaction contemplated hereby.

      6.      CONDITIONS OF OBLIGATIONS OF THE UNDERWRITERS.

              The several obligations of the Underwriters to purchase the Firm
      Shares on the Closing Date and the Option Shares, if any, on the Option
      Closing Date are subject to the accuracy, in all material respects, as of
      the Closing Date or the Option Closing Date, as the case may be, of the
      representations and warranties of the Company contained herein, and to
      the performance by the Company of its covenants and obligations hereunder
      and to the following additional conditions:

              (a)  The Registration Statement and all post-effective amendments
      thereto shall have become effective and any and all filings required by
      Rule 424 and Rule 430A of the Rules and Regulations shall have been made,
      and any request of the Commission for additional information (to be
      included in the Registration Statement or otherwise) shall have been
      disclosed to the Representatives and complied with to their reasonable
      satisfaction.  No stop order suspending the effectiveness of the
      Registration Statement, as amended from time to time, shall have been
      issued and no proceedings for that purpose shall have been taken or, to
      the knowledge of the Company, shall be contemplated by the Commission and
      no injunction, restraining order, or order of any nature by a Federal or
      state court of competent jurisdiction shall have been issued as of the
      Closing Date which would prevent the issuance of the Shares.

              (b)  The Representatives shall have received on the Closing Date
      or the Option Closing Date, as the case may be, the opinion of Wilson
      Sonsini Goodrich & Rosati, P.C., counsel for the Company, dated the
      Closing Date or the Option Closing Date, as the case may be, addressed to
      the Underwriters (and stating that it may be relied upon by counsel to
      the Underwriters) to the effect that:

                       (i)  The Company has been duly organized and is validly
              existing as a corporation in good standing under the laws of the
              State of Delaware with corporate power and authority to own or
              lease its properties and conduct its business as described in the
              Registration Statement and the Company is duly qualified to
              transact business in all jurisdictions in which the conduct of
              its business requires such qualification, or in which the failure
              to qualify would have a materially adverse effect upon the
              business of the Company.





                                       12
<PAGE>   13
                       (ii)  The Company had authorized and outstanding capital
              stock as of February 28, 1997 as set forth under the caption
              "Capitalization" in the Prospectus and on the assumptions stated
              therein; the authorized shares of the Company's Common Stock have
              been duly authorized; the outstanding shares of the Company's
              Common Stock have been duly authorized and validly issued and are
              fully paid and non-assessable; the statements set forth in the
              Prospectus under the caption "Description of Capital Stock,"
              insofar as they purport to constitute a summary of the terms of
              the Company's Common Stock, fairly summarize such terms in all
              material respects; the certificates for the Shares, assuming they
              are in the form filed with the Commission, are in due and proper
              form in all material respects; the shares of Common Stock,
              including the Option Shares, if any, to be sold by the Company
              pursuant to this Agreement have been duly authorized and will be
              validly issued, fully paid and non-assessable when issued and
              paid for as contemplated by this Agreement; and no preemptive
              rights of stockholders exist under Delaware law, in the Charter 
              or Bylaws of the Company or in any agreement filed as an exhibit 
              to the Registration Statement with respect to any of the Shares 
              or the issue or sale thereof.

                       (iii)  Except as described in or contemplated by the
              Prospectus, to the knowledge of such counsel, there are no
              outstanding securities of the Company convertible or exchangeable
              into or evidencing the right to purchase or subscribe for any
              shares of capital stock of the Company and there are no
              outstanding or authorized options, warrants or rights of any
              character obligating the Company to issue any shares of its
              capital stock or any securities convertible or exchangeable into
              or evidencing the right to purchase or subscribe for any shares
              of such stock; and except as described in the Prospectus, to the
              knowledge of such counsel, no holder of any securities of the
              Company or any other person has the right, contractual or
              otherwise, which has not been satisfied or effectively waived,
              to cause the Company to sell or otherwise issue to them, or to
              permit them to underwrite the sale of, any of the Shares or the
              right to have any Common Shares or other securities of the
              Company included in the Registration Statement or the right, as a
              result of the filing of the Registration Statement, to require
              registration under the Act of any shares of Common Stock or other
              securities of the Company.

                       (iv)  Based solely on the oral advice of the staff of
              the Commission, the Registration Statement has become effective
              under the Act and, to the knowledge of such counsel, no stop
              order proceedings with respect thereto have been instituted or
              are pending or threatened under the Act.

                       (v)  The Registration Statement, the Prospectus and each
              amendment or supplement thereto comply as to form in all material
              respects with the requirements of the Act and the applicable
              rules and regulations thereunder (except that such counsel need
              express no opinion as to the financial statements, related notes
              and schedules therein or the other financial and statistical data





                                       13
<PAGE>   14
              included therein or as to information supplied by the
              Underwriters for use therein).

                       (vi)  The statements under the captions "Description of
              Capital Stock" and "Shares Eligible for Future Sale" in the
              Prospectus, insofar as such statements constitute a summary of
              documents referred to therein or matters of law, fairly summarize
              in all material respects the information called for with respect
              to such documents and matters.

                       (vii)  Such counsel does not know of any contracts or
              documents required to be filed as exhibits to the Registration
              Statement or described in the Registration Statement or the
              Prospectus which are not so filed or described as required, and
              such contracts and documents as are summarized in the
              Registration Statement or the Prospectus are fairly summarized in
              all material respects.

                       (viii)  Such counsel knows of no material legal or
              governmental proceedings pending or threatened in writing against
              the Company except as set forth in the Prospectus where such
              proceeding would be reasonably likely to have a material adverse
              effect on the Company's financial condition or results of
              operations.

                       (ix)  The execution and delivery of this Agreement and
              the consummation of the transactions herein contemplated do not
              and will not result in a breach of any of the terms or provisions
              of, or constitute a default under, the Charter or bylaws of the
              Company, or any agreement or instrument known to such counsel
              [and filed as an exhibit to the Registration Statement] to which
              the Company is a party or by which the Company may be bound,
              except where such breach or default would not have a material
              adverse effect on the business or financial condition of the
              Company.

                       (x)  This Agreement has been duly authorized, executed
              and delivered by the Company.

                       (xi)  No approval, consent, order, authorization,
              designation, declaration or filing by or with any regulatory,
              administrative or other governmental body is necessary in
              connection with the execution and delivery of this Agreement and
              the consummation of the transactions herein contemplated (other
              than as may be required by the NASD or as required by State
              securities and Blue Sky laws as to which such counsel need
              express no opinion) except such as have been obtained or made,
              specifying the same.

                       (xii)  The Company is not an investment company as such
              term is defined in the 1940 Act.

              In rendering such opinion Wilson Sonsini Goodrich & Rosati, P.C.,
      may rely as to matters governed by the laws of states other than
      California or federal laws on local counsel in such jurisdictions,
      provided that in each case Wilson Sonsini Goodrich & Rosati, P.C., shall
      state that they believe that they and the Underwriters are justified in
      relying on such other counsel.  In addition to the matters set forth
      above, such opinion shall also include a statement to the effect that
      nothing has come to the attention of such counsel which leads them to
      believe that (i) the Registration Statement, at the time it became
      effective under the Act (but after giving effect to any modifications
      incorporated therein pursuant to Rule 430A under the Act) and as of the
      Closing Date or the Option Closing Date, as the case may be, contained an
      untrue statement of a material fact or omitted to state a material fact
      required to be stated therein or necessary to make the statements therein
      not misleading, and (ii) the Prospectus, or any supplement thereto, on
      the date it was filed pursuant to the Rules and Regulations and as of the
      Closing Date or the Option Closing Date, as the case may be, contained an
      untrue statement of a material fact or omitted to state a material fact
      necessary in order to make the statements, in the light of the
      circumstances under which they are made, not misleading (except that such
      counsel need express no view as to financial statements, related notes,
      schedules and other financial and statistical information therein).  With
      respect to such statement, Wilson Sonsini Goodrich & Rosati, P.C., may
      state that their belief is based upon the procedures set forth therein,
      but is without independent check and verification.

              (c)  The Representatives shall have received from Pillsbury
      Madison & Sutro LLP, counsel for the Underwriters, an opinion dated the
      Closing Date or the Option Closing Date, as the case may be,
      substantially to the effect specified in subparagraphs (ii) and (iv) of
      Paragraph (b) of this Section 6, and that the Company is a duly organized
      and validly existing corporation under the laws of the State of Delaware.
      In rendering such opinion Pillsbury Madison & Sutro LLP may rely as to
      all matters governed other than by the laws of the State of California,
      the State of Delaware or federal laws on the opinion of counsel referred
      to in Paragraph (b) of this Section 6.  In addition to the matters set
      forth above, such opinion shall also include a statement to the effect
      that nothing has come to the attention of such counsel which leads them
      to believe that (i) the Registration Statement, or any amendment thereto,
      as of the time it became effective under the Act (but after giving effect
      to any modifications incorporated therein pursuant to Rule 430A under the
      Act) as of the Closing Date or the Option Closing Date, as the case may
      be, contained an untrue statement of a material fact or omitted to state
      a material fact required to be stated therein or necessary to make the
      statements therein not misleading, and (ii) the Prospectus, or any
      supplement thereto, on the date it was filed pursuant to the Rules and
      Regulations and as of the Closing Date or the Option Closing Date, as the
      case may be, contained an untrue statement of a material fact or omitted
      to state a material fact, necessary in order to make the statements, in
      the light of the circumstances under which they are made, not misleading
      (except that such counsel need express no view as to financial
      statements, related notes, financial data, schedules and other financial
      and statistical information therein).  With respect to such statement,
      Pillsbury Madison & Sutro LLP may state that their belief is based upon
      the procedures set forth therein, but is without independent check and
      verification.

              (d)  The Representatives shall have received at or prior to the
      Closing Date from Pillsbury Madison & Sutro LLP a memorandum or summary,
      in form and substance satisfactory to the Representatives, with respect
      to the qualification for offering and sale by the Underwriters of the
      Shares under the State securities or Blue Sky laws of such jurisdictions
      as the Representatives may reasonably have designated to the Company.

              (e)  You shall have received, on each of the dates hereof, the
      Closing Date and the Option Closing Date, as the case may be, a letter
      dated the date hereof, the Closing Date or the Option Closing Date, as
      the case may be, in form and substance satisfactory to you, of Deloitte &
      Touche LLP confirming that they are independent public accountants within
      the meaning of the Act and the applicable published Rules and Regulations
      thereunder and stating that in their opinion the financial statements and
      schedules examined by them and included in the Registration Statement
      comply in form in all material respects with the applicable accounting
      requirements of the Act and the related published Rules and Regulations;
      and containing such other statements and information as is ordinarily
      included in accountants' "comfort letters" to Underwriters with respect
      to the financial statements and certain financial and statistical
      information contained in the Registration Statement and Prospectus.

              (f)  The Representatives shall have received on the Closing Date
      or the Option Closing Date, as the case may be, a certificate or
      certificates of the Chief Executive Officer and the Chief Financial
      Officer of the Company to the effect that, as of the Closing Date or the
      Option Closing Date, as the case may be, each of them severally
      represents as follows:

                       (i)  The Registration Statement has become effective
              under the Act and no stop order suspending the effectiveness of
              the Registration Statement has been issued, and no proceedings
              for such purpose have been taken or are, to his knowledge,
              contemplated by the Commission;

                       (ii)  The representations and warranties of the Company
              contained in Section 1 hereof are true and correct as of the
              Closing Date or the Option Closing Date, as the case may be;

                       (iii)  All filings required to have been made pursuant to
              Rules 424 or 430A under the Act have been made;

                       (iv)  He or she has carefully examined the Registration
              Statement and the Prospectus and, in his opinion, as of the
              effective date of the Registration Statement, the statements
              contained in the Registration Statement were true and correct,
              and such Registration Statement and Prospectus did not omit to
              state a material fact required to be stated therein or necessary
              in order to make the statements therein not misleading, and since
              the effective date of the Registration Statement, no event has
              occurred which should have been set forth in a





                                       16
<PAGE>   17
              supplement to or an amendment of the Prospectus which has not
              been so set forth in such supplement or amendment; and

                       (v)  Since the respective dates as of which information
              is given in the Registration Statement and Prospectus, there has
              not been any material adverse change or any development involving
              a prospective material adverse change in or affecting the
              financial condition of the Company or the earnings, business,
              management, properties, assets, rights, operations or financial
              condition of the Company, whether or not arising in the ordinary
              course of business.

              (g)  The Company shall have furnished to the Representatives such
      further certificates and documents confirming the representations and
      warranties, covenants and conditions contained herein and related matters
      as the Representatives may reasonably have requested.

              (h)  The Firm Shares and Option Shares, if any, have been
      approved for designation upon notice of issuance on the Nasdaq National
      Market.

              (i)  The Lockup Agreements described in Section 4 (j) are in full
      force and effect.

              The opinions and certificates mentioned in this Agreement shall
      be deemed to be in compliance with the provisions hereof only if they are
      in all material respects satisfactory to the Representatives and to
      Pillsbury Madison & Sutro LLP, counsel for the Underwriters.

              If any of the conditions hereinabove provided for in this Section
      6 shall not have been fulfilled when and as required by this Agreement to
      be fulfilled, the obligations of the Underwriters hereunder may be
      terminated by the Representatives by notifying the Company of such
      termination in writing or by telegram at or prior to the Closing Date or
      the Option Closing Date, as the case may be.

              In such event, the Company and the Underwriters shall not be
      under any obligation to each other (except to the extent provided in
      Sections 5 and 8 hereof).

      7.      CONDITIONS OF THE OBLIGATIONS OF THE COMPANY.

              The obligations of the Company to sell and deliver the portion of
      the Shares required to be delivered as and when specified in this
      Agreement are subject to the conditions that at the Closing Date or the
      Option Closing Date, as the case may be, no stop order suspending the
      effectiveness of the Registration Statement shall have been issued and in
      effect or proceedings therefor initiated or threatened.

      8.      INDEMNIFICATION.

              (a)  The Company agrees to indemnify and hold harmless each
      Underwriter and each person, if any, who controls any Underwriter within
      the meaning of the Act, against any losses, claims, damages or
      liabilities to which such Underwriter or any such controlling person may
      become subject under the Act or otherwise, insofar as such losses,
      claims, damages or liabilities (or actions or proceedings in respect
      thereof) arise out of or are based upon (i) any untrue statement or
      alleged untrue statement of any material fact contained in the
      Registration Statement, any Preliminary Prospectus, the Prospectus or any
      amendment or supplement thereto, or (ii) the omission or alleged omission
      to state therein a material fact required to be stated therein or
      necessary to make the statements therein not misleading; and will
      reimburse each Underwriter and each such controlling person upon demand
      for any legal or other expenses reasonably incurred by such Underwriter
      or such controlling person in connection with investigating or defending
      any such loss, claim, damage or liability, action or proceeding or in
      responding to a subpoena or governmental inquiry related to the offering
      of the Shares, whether or not such Underwriter or controlling person is a
      party to any action or proceeding; provided, however, that the Company
      will not be liable in any such case to the extent that any such loss,
      claim, damage or liability (i) arises out of or is based upon an untrue
      statement or alleged untrue statement, or omission or alleged omission
      made in the Registration Statement, any Preliminary Prospectus, the
      Prospectus, or such amendment or supplement, in reliance upon and in
      conformity with written information furnished to the Company by or
      through the Representatives specifically for use in the preparation
      thereof or (ii) to the extent it is finally judicially determined by a
      court of competent jurisdiction that such loss, claim, damage or
      liability resulted directly from any such acts or failures to act
      undertaken or omitted to be taken by such Underwriter through its gross
      negligence or willful misconduct; and provided further that the Company
      will not be liable to the extent that such loss, claim, damage or
      liability results from an untrue statement of a material fact contained
      in, or the omission of a material fact from, the Preliminary Prospectus,
      which untrue statement or omission was corrected in the Prospectus (as
      then amended or supplemented) if the Underwriters sold Shares to the
      person alleging such loss, claim, damage or liability without sending or
      giving, at or prior to the written confirmation of such sale, a copy of
      the Prospectus (as then amended or supplemented) if the Company had
      previously furnished copies thereof to the Underwriters within a
      reasonable amount of time prior to such sale or such confirmation, and
      the Underwriters failed to deliver the corrected Prospectus to such
      person.  This indemnity agreement will be in addition to any liability 
      which the Company may otherwise have.

              (b)  Each Underwriter severally and not jointly will indemnify
      and hold harmless the Company, each of its directors, each of its
      officers who have signed the Registration Statement and each person, if
      any, who controls the Company within the meaning of the Act, against any
      losses, claims, damages or liabilities to which the Company or any such
      director, officer, or controlling person may become subject under the Act
      or otherwise, insofar as such losses, claims, damages or liabilities (or
      actions or proceedings in respect





                                       18
<PAGE>   19
      thereof) arise out of or are based upon (i)  any untrue statement or
      alleged  untrue statement of any material fact contained in the
      Registration Statement, any Preliminary Prospectus, the Prospectus or any
      amendment or supplement thereto, or (ii) the omission or the alleged
      omission to state therein a material fact required to be stated therein
      or necessary to make the statements therein not misleading in the light
      of the  circumstances under which they were made; and will reimburse any
      legal or other expenses reasonably incurred by the Company or any such
      director, officer, or controlling person in connection with investigating
      or defending any such loss, claim, damage, liability, action or
      proceeding; provided, however, that each Underwriter will be liable in
      each case to the extent, but only to the extent, that such untrue
      statement or alleged untrue statement or omission or alleged omission has
      been made in the Registration Statement, any Preliminary Prospectus, the
      Prospectus or such amendment or supplement, in reliance upon and in
      conformity with written information furnished to the Company by or
      through the Representatives specifically for use in the preparation
      thereof.  This indemnity agreement will be in addition to any liability
      which such Underwriter may otherwise have.

              (c)  In case any proceeding (including any governmental
      investigation) shall be instituted involving any person in respect of
      which indemnity may be sought pursuant to this Section 8, such person
      (the "indemnified party") shall promptly notify the person against whom
      such indemnity may be sought (the "indemnifying party") in writing.  No
      indemnification provided for in Section 8(a) or (b) shall be available to
      any party who shall fail to give notice as provided in this Section 8(c)
      if the party to whom notice was not given was unaware of the proceeding
      to which such notice would have related and was materially prejudiced by
      the failure to give such notice, but the failure to give such notice
      shall not relieve the indemnifying party or parties from any liability
      which it or they may have to the indemnified party for contribution or
      otherwise than on account of the provisions of Section 8(a) or (b).  In
      case any such proceeding shall be brought against any indemnified party
      and it shall notify the indemnifying party of the commencement thereof,
      the indemnifying party shall be entitled to participate therein and, to
      the extent that it shall wish, jointly with any other indemnifying party
      similarly notified, to assume the defense thereof, with counsel
      satisfactory to such indemnified party and shall pay as incurred the fees
      and disbursements of such counsel related to such proceeding.  In any
      such proceeding, any indemnified party shall have the right to retain its
      own counsel at its own expense.  Notwithstanding the foregoing, the
      indemnifying party shall pay as incurred (or within 30 days of
      presentation) the fees and expenses of the counsel retained by the
      indemnified party in the event  (i) the indemnifying party and the
      indemnified party shall have mutually agreed to the retention of such
      counsel, (ii) the named parties to any such proceeding (including any
      impleaded parties) include both the indemnifying party and the
      indemnified party and representation of both parties by the same counsel
      would be inappropriate due to actual or potential differing interests
      between them or [(iii) the indemnifying party shall have failed to assume
      the defense and employ counsel acceptable to the indemnified party within
      a reasonable period of time after notice of commencement of the action].
      It is understood that the indemnifying party shall not, in connection
      with any proceeding or related proceedings in the same jurisdiction, be





                                       19
<PAGE>   20
      liable for the reasonable fees and expenses of more than one separate
      firm for all such indemnified parties.  Such firm shall be designated in
      writing by you in the case of parties indemnified pursuant to Section
      8(a) and by the Company in the case of parties indemnified pursuant to
      Section 8(b).  The indemnifying party shall not be liable for any
      settlement of any proceeding effected without its written consent but if
      settled with such consent or if there be a final judgment for the
      plaintiff, the indemnifying party agrees to indemnify the indemnified
      party from and against any loss or liability by reason of such settlement
      or judgment.  In addition, the indemnifying party will not, without the
      prior written consent of the indemnified party, settle or compromise or
      consent to the entry of any judgment in any pending or threatened claim,
      action or proceeding of which indemnification may be sought hereunder
      (whether or not any indemnified party is an actual or potential party to
      such claim, action or proceeding) unless such settlement, compromise or
      consent includes an unconditional release of each indemnified party from
      all liability arising out of such claim, action or proceeding.

              (d)  If the indemnification provided for in this Section 8 is
      unavailable to or insufficient to hold harmless an indemnified party
      under Section 8(a) or (b) above in respect of any losses, claims, damages
      or liabilities (or actions or proceedings in respect thereof) referred to
      therein, then each indemnifying party shall contribute to the amount paid
      or payable by such indemnified party as a result of such losses, claims,
      damages or liabilities (or actions or proceedings in respect thereof) in
      such proportion as is appropriate to reflect the relative benefits
      received by the Company on the one hand and the Underwriters on the other
      from the offering of the Shares.  If, however, the allocation provided by
      the immediately preceding sentence is not permitted by applicable law
      then each indemnifying party shall contribute to such amount paid or
      payable by such indemnified party in such proportion as is appropriate to
      reflect  not only such relative benefits but also the relative fault of
      the Company on the one hand and the Underwriters on the other in
      connection with the statements or omissions which resulted in such
      losses, claims, damages or liabilities, (or actions or proceedings in
      respect thereof), as well as any other relevant equitable considerations.
      The relative benefits received by the Company on the one hand and the
      Underwriters on the other shall be deemed to be in the same proportion as
      the total net proceeds from the offering (before deducting expenses)
      received by the Company bear to the total underwriting discounts and
      commissions received by the Underwriters, in each case as set forth in
      the table on the cover page of the Prospectus.  The relative fault shall
      be determined by reference to, among other things, whether the untrue or
      alleged untrue statement of a material fact or the omission or alleged
      omission to state a material fact relates to information supplied by the
      Company on the one hand or the Underwriters on the other and the parties'
      relative intent, knowledge, access to information and opportunity to
      correct or prevent such statement or omission.

              The Company, and the Underwriters agree that it would not be just
      and equitable if contributions pursuant to this Section 8(d) were
      determined by pro rata allocation (even if the Underwriters were treated
      as one entity for such purpose) or by any other method of allocation
      which does not take account of the equitable considerations referred to





                                       20
<PAGE>   21
      above in this Section 8(d).  The amount paid or payable by an indemnified
      party as a result of the losses, claims, damages or liabilities (or
      actions or proceedings in respect thereof) referred to above in this
      Section 8(d) shall be deemed to include any legal or other expenses
      reasonably incurred by such indemnified party in connection with
      investigating or defending any such action or claim.  Notwithstanding the
      provisions of this subsection (d), (i) no Underwriter shall be required
      to contribute any amount in excess of the underwriting discounts and
      commissions applicable to the Shares purchased by such Underwriter, and
      (ii) no person guilty of fraudulent misrepresentation (within the meaning
      of Section 11(f) of the Act) shall be entitled to contribution from any
      person who was not guilty of such fraudulent misrepresentation.  The
      Underwriters' obligations in this Section 8(d) to contribute are several
      in proportion to their respective underwriting obligations and not joint.

              (e)  In any proceeding relating to the Registration Statement,
      any Preliminary Prospectus, the Prospectus or any supplement or amendment
      thereto, each party against whom contribution may be sought under this
      Section 8 hereby consents to the jurisdiction of any court having
      jurisdiction over any other contributing party, agrees that process
      issuing from such court may be served upon him or it by any other
      contributing party and consents to the service of such process and agrees
      that any other contributing party may join him or it as an additional
      defendant in any such proceeding in which such other contributing party
      is a party.

              (f)  Any losses, claims, damages, liabilities or expenses for
      which an indemnified party is entitled to indemnification or contribution
      under this Section 8 shall be paid by the indemnifying party to the
      indemnified party as such losses, claims, damages, liabilities or
      expenses are incurred.  The indemnity and contribution agreements
      contained in this Section 8 and the representations and warranties of the
      Company set forth in this Agreement shall remain operative and in full
      force and effect, regardless of (i) any investigation made by or on
      behalf of any Underwriter or any person controlling any Underwriter, the
      Company, its directors or officers or any persons controlling the
      Company, (ii) acceptance of any Shares and payment therefor hereunder,
      and (iii) any termination of this Agreement.  A successor to any
      Underwriter, or to the Company, its directors or officers, or any person
      controlling the Company, shall be entitled to the benefits of the
      indemnity, contribution and reimbursement agreements contained in this
      Section 8.

      9.      DEFAULT BY UNDERWRITERS.

              If on the Closing Date or the Option Closing Date, as the case
      may be, any Underwriter shall fail to purchase and pay for the portion of
      the Shares which such Underwriter has agreed to purchase and pay for on
      such date (otherwise than by reason of any default on the part of the
      Company), you, as Representatives of the Underwriters, shall use your
      reasonable efforts to procure within 36 hours thereafter one or more of
      the other Underwriters, or any others, to purchase from the Company such
      amounts as may be agreed upon and upon the terms set forth herein, the
      Firm Shares or Option Shares,





                                       21
<PAGE>   22
      as the case may be, which the defaulting Underwriter or Underwriters
      failed to purchase.  If during such 36 hours you, as such
      Representatives, shall not have procured such other Underwriters, or any
      others, to purchase the Firm Shares or Option Shares, as the case may be,
      agreed to be purchased by the defaulting Underwriter or Underwriters,
      then  (a) if the aggregate number of shares with respect to which such
      default shall occur does not exceed 10% of the Firm Shares or Option
      Shares, as the case may be, covered hereby, the other Underwriters shall
      be obligated, severally, in proportion to the respective numbers of Firm
      Shares or Option Shares, as the case may be, which they are obligated to
      purchase hereunder, to purchase the Firm Shares or Option Shares, as the
      case may be, which such defaulting Underwriter or Underwriters failed to
      purchase, or  (b) if the aggregate number of shares of Firm Shares or
      Option Shares, as the case may be, with respect to which such default
      shall occur exceeds 10% of the Firm Shares or Option Shares, as the case
      may be, covered hereby, the Company or you as the Representatives of the
      Underwriters will have the right, by written notice given within the next
      36-hour period to the parties to this Agreement, to terminate this
      Agreement without liability on the part of the non-defaulting
      Underwriters or of the Company except to the extent provided in Section 8
      hereof.  In the event of a default by any Underwriter or Underwriters, as
      set forth in this Section 9, the Closing Date or Option Closing Date, as
      the case may be, may be postponed for such period, not exceeding seven
      days, as you, as Representatives, may determine in order that the
      required changes in the Registration Statement or in the Prospectus or in
      any other documents or arrangements may be effected.  The term
      "Underwriter" includes any person substituted for a defaulting
      Underwriter.  Any action taken under this Section 9 shall not relieve any
      defaulting Underwriter from liability in respect of any default of such
      Underwriter under this Agreement.

      10.     NOTICES.

      purposes of Rule 436(g) under the Exchange Act); (vii) the suspension of
      trading of the Company's common stock by the Commission on the Nasdaq
      National Market or (viii) the taking of any action by any governmental
      body or agency in respect of its monetary or fiscal affairs which in your
      reasonable opinion has a material adverse effect on the securities
      markets in the United States; or

              (c)  as provided in Sections 6 and 9 of this Agreement.

                          MANNER OF CONVERSION OF STOCK

         3.1 Aspec California Common Stock. Upon the Effective Date of the
Merger, each share of Aspec California Common Stock issued and outstanding
immediately prior thereto shall, by virtue of the Merger and without any action
by the Constituent Corporations, the holder of such shares or any other person,
be converted into and exchanged for one fully paid and nonassessable share of
Common Stock, $0.001 par value, of the Surviving Corporation.

         3.3 Aspec California Plans and Options. Upon the Effective Date of the

Stock shall become an option convertible into the Surviving Corporation's Common
Stock on the basis of one share of the Surviving Corporation's Common Stock for
each share of Aspec California Common Stock issuable pursuant to any such option
on the same terms and conditions and at an exercise price per share equal to the
exercise price applicable to any such Aspec California option at the Effective
Date of the Merger.

         A number of shares of the Surviving Corporation's Common Stock shall be

each holder of an outstanding certificate representing shares of Aspec
California capital stock may, at such stockholder's option, surrender the same

exchange therefor a certificate or certificates representing the number of
shares of the appropriate class and series of the Surviving Corporation's
capital stock into which the surrendered shares were converted as herein
provided. Until so surrendered, each outstanding certificate theretofore
representing shares of Aspec California capital stock shall be deemed for all
purposes to represent the number of whole shares of the appropriate class and
series of the Surviving

stock were converted in the Merger.

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

         Each certificate representing capital stock of the Surviving
Corporation so issued in the Merger shall bear the same legends, if any, with
respect to the restrictions on transferability as the certificates of Aspec
California so converted and given in exchange therefor, unless otherwise
determined by the Board of Directors of the Surviving Corporation in compliance
with applicable laws.

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

         RE: REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

         We have examined the Registration Statement on Form S-1 filed by you
with the Securities and Exchange Commission on March 6, 1997 (Registration
No. 333-22913), as amended (the "Registration Statement"), in connection with
the registration under the Securities Act of 1933, as amended, of up to
4,600,000 shares of your Common Stock, par value $0.001 per share (the
"Shares"). The Shares include an over-allotment option granted to the
underwriters of the offering to purchase 600,000 shares. We understand that the
Shares are to be sold to the underwriters of the offering for resale to the
public as described in the Registration Statement. As your legal counsel, we
have examined the proceedings taken, and are familiar with the proceedings
proposed to be taken, by you in connection with the sale and issuance of the
Shares.         

         It is our opinion that, upon completion of the proceedings being taken
or contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, including the proceedings being taken in order to permit such
transaction to be carried out in accordance with applicable state securities
laws, the Shares, when issued and sold in the manner described in the
Registration Statement and in accordance with the resolutions adopted by the
Board of Directors of the Company, will be legally and validly issued, fully
paid and nonassessable.

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

                                       Very truly yours,
