PART I.

ITEM 1.   BUSINESS

         Cadence Design Systems, Inc. ("Cadence" or the "Company") develops,
markets and supports electronic design automation software tools that automate,
enhance and accelerate the design and verification of integrated circuits
("ICs") and electronic systems. The Company combines its technology with
services to help optimize its customers' product development processes. This
combination of products and services, generally referred to as EDA, is used by
companies throughout the world to design semiconductors, computer systems and
peripherals, telecommunications and networking equipment, mobile/wireless
devices, automotive components, consumer products and other advanced
electronics.

         Cadence was formed as a result of the merger of SDA Systems, Inc.
("SDA") into ECAD, Inc. ("ECAD") in May 1988. In addition to certain smaller
acquisitions from 1989 through 1994, in December 1991, Cadence merged with Valid
Logic Systems Incorporated ("Valid"), a company that developed and supported EDA
software used to design electronic systems, printed circuit boards ("PCBs") and
applications for electronic product designs involving advanced packaging
technology such as hybrids and multi-chip modules ("MCMs"). In February 1989,
Valid had acquired Integrated Measurement Systems, Inc. ("IMS"), a company that
manufactures and markets verification systems used in testing prototype
application specific integrated circuits ("ASICs"). During 1995, Cadence and IMS
sold to the public approximately 3.0 million shares of common stock, of which
approximately 2.6 million shares were sold by the Company as the sole selling
stockholder of IMS. As Cadence remains the majority stockholder with an
ownership percentage of approximately 55%, the consolidated financial statements
of the Company for all periods presented include the accounts of IMS after
elimination of intercompany accounts and transactions and minority interest
adjustments. As part of its overall investment strategy, the Company has
committed to participate in a venture capital partnership, Telos Venture
Partners (the "Partnership"), as a limited partner. The Partnership's purpose is
to make venture capital investments in start-up and growth oriented businesses,
with some emphasis on businesses in the semiconductor and software industries.
The Company's total investment of $25.0 million will be made over the next three
to four years.

         EDA tools are used primarily by electronic designers to develop
electronic circuits and systems. Cadence's sophisticated tools are used to
analyze, simulate, implement and verify electronic designs. By using these tools
to automate significant parts of the design process, electronic engineers can
focus their time on developing the intellectual content of the integrated
circuit or electronic system, which is at the heart of a company's
competitiveness. In addition, powerful design automation software tools let
design architects and engineers build abstract models of chips, simulate their
behavior, and analyze their physical attributes for acceptable performance. EDA
also ensures that the product design can be manufactured and can work as
intended. The result is significant productivity and accuracy improvements over
earlier generation approaches to design, enabling customers to develop
increasingly complex, high-quality electronic products with accelerated
time-to-market schedules.

         As the process of designing advanced silicon and systems has grown
increasingly complicated, even with the most sophisticated EDA tools, product
developers' resources have become strained in their ability to meet demanding
market requirements. In response to this challenge, Cadence has developed a
unique approach which combines the industry's most comprehensive line of
software tools with an expert team of experienced support, design and process
service professionals. This approach not only gives customers access to
leading-edge design technology, but also improves the overall productivity of
their design process. The Company's services range from advanced tools training
to methodology assessment to joint design work with customers and to complete
outsourcing of its customers' design work. As an example, in March 1995, the
Company signed a $75 million agreement with Unisys Corporation to assume a
substantial portion of Unisys' internal silicon design operations. This
comprehensive approach to working with customers has been widely accepted in the
marketplace, as evidenced by a 132% increase in the Company's service revenue in
1995 as compared to 1994.

         The third component of Cadence's business model is customer support,
which the Company believes is a key factor in successfully marketing EDA
products and generating repeat orders. A 

                                       1
<PAGE>   4
majority of Cadence's customers have purchased one-year renewable maintenance
contracts. These product maintenance contracts entitle the customers to product
updates, documentation and ongoing support. The backbone of global customer
support is the customer response center program. These centers give Cadence
customers worldwide access to solution and product experts. A dedicated team of
application engineers is available to address customer application issues as
well as to provide links between customers and Cadence's product developers.

THE ELECTRONIC PRODUCT DEVELOPMENT CYCLE

         EDA tools assist with the two major functions of the electronic product
development cycle: electrical design, often referred to as CAE, and physical
design, often referred to as computer aided design ("CAD").

         The electrical design process, or CAE, involves describing the
behavioral, functional and structural attributes of an IC or electronic system.
This process involves creating a design description, simulating the design to
assure it is void of electrical defects and refining the description to meet
predetermined design specifications. The first step in the CAE process is
creation of the design description (often called design entry, design capture or
schematic capture). To handle the complexity of large designs, design entry
often consists of several levels of design abstraction using a variety of design
capture techniques. The most common techniques are the use of block diagrams,
equations or special design description languages referred to as Hardware
Description Language ("HDL").

         For digital designs, the most common HDLs are Verilog(R) HDL, a
language originally developed by Cadence that is now in the public domain and an
Institute of Electronic and Electrical Engineers ("IEEE") standard, and VHSIC
HDL(TM) ("VHDL"), a language that is also an IEEE standard and backed by the
U.S. Department of Defense. Verilog(R) and VHDL are both supported by Cadence as
well as many other EDA vendors. Similar standard HDLs are emerging for analog
design. Cadence introduced an analog extension to Verilog(R) called AHDL in 1994
and is seeking to make it an industry standard.

         Before an IC or PCB can be manufactured, high level design descriptions
must be detailed into a lower level of abstraction referred to as structural
design. This process can be done manually or automated using a process called
logic synthesis. In structural design, the engineer specifically defines
components, their interconnections and associated physical properties. This
description can be in a form of a text file produced by logic synthesis or a
structural diagram called a schematic. In structural design, critical design
time is saved by pulling components from an electronic library and including
them in the design, rather than recreating every symbol and all data for each
design. A database containing the design's electrical characteristics,
interconnections and specific design rules, is automatically created and used as
the foundation for subsequent design steps.

         Simulation is used throughout the CAE process to catch costly design
errors before the design is manufactured. In addition, simulation enables
engineers to quickly explore various design alternatives. It can be performed at
different levels of design abstraction and with mixed levels of abstraction.
This enables a designer to verify the conceptual, structural and performance
aspects of the design. A key element in the simulation process is the use of
component libraries containing software models of commonly used parts. These are
either developed and supplied by Cadence, the designer, application specific
integrated circuit ("ASIC") vendors or independent modeling companies, that have
certified their libraries for use with Cadence's simulation products.

         When the design is determined to be functionally correct, the designer
generates a netlist. A netlist is a non-graphical description, in list form, of
all design components and interconnections. The netlist is the link between the
CAE design environment and the CAD process.

CAE PRODUCTS

         Cadence is a mainstay in the CAE market primarily based on its strong
market presence in logic simulation. Cadence's Verilog(R) HDL logic simulator,
Verilog XL(TM), is used by numerous ASIC vendors and supports over 185 ASIC
libraries. Cadence also has established a significant position in the VHDL
design market with its Leapfrog(TM) VHDL simulator due to its strong performance
and robust design environment.

                                       2
<PAGE>   5
         Cadence was the pioneer in offering a solution for companies that
choose to utilize a mixed language (both Verilog(R) HDL and VHDL(R)) design
approach with its 1994 introduction of Model Import. This product, sold as an
adjunct to either Verilog XL(TM) or Leapfrog(TM), enables designers to import a
textual description block of Verilog(R) or VHDL(R) into their native design
environment. In 1995, Cadence introduced a next generation mixed language
solution based on a unique simulation architecture called INCA(TM). The INCA(TM)
architecture utilizes a state of the art simulation technique called native
compiled code generation which delivers the fastest throughput of any
conventional software approach.

         Cadence also offers a comprehensive suite of tools for logic synthesis.
The Synergy(TM) product line provides designers the ability to easily target
their design for implementation into an ASIC, Field Programmable Gate Array
("FPGA") or Programmable Logic Device ("PLD") design. Synergy(TM) enables
designers to make critical tradeoffs between area, power and performance to
optimize their design based on specific design requirements. In addition,
Synergy(TM) offers advanced design-for-test capability with built in test
synthesis support. The combination of Cadence's simulation and synthesis
capabilities provide designers with a core design environment that supports the
most broadly used top-down design methodology in the industry today.

         With the advent of deep sub-micron technology, companies need to adopt
new methodologies and will require innovative design automation tools to enable
the successful completion of complex designs. The key to successfully designing
chips implemented in 0.5m technology and below is utilizing knowledge of the
physical design process in the logic design space. With its current industry
position in IC place and route, Cadence is strongly positioned to develop and
deliver next generation logic design tools that will provide designers with
these mandatory capabilities. During 1994, Cadence introduced Silicon
Synthesis(TM) which provides the ability to optimize logic based on actual
physical implementation. This approach enables designers to avoid costly design
iterations caused by lack of timing consistency between a logic description and
final implementation. In 1995, the Company introduced SiliconQuest(TM), an
advanced high level chip planning environment that allows engineers to
accurately predict physical effects that are used to provide guidelines for
logic optimization. In addition, SiliconQuest(TM) provides a foundation for the
methodology shift required to combat deep sub-micron design issues.

IC DESIGN PRODUCTS

         Cadence has long been a leader in the IC CAD market with high
performance technology in the custom layout, automatic place and route and
verification areas. These technologies are tightly integrated with the Company's
suite of CAE tools to offer one of the industry's most comprehensive
front-to-back design solutions.

         The Company's custom layout portfolio is anchored by the Virtuoso(TM)
product family. This suite consists of tools for basic layout editing, design
compaction, layout synthesis and device-level editing. In 1995, the Company
introduced Virtuoso(TM) FastChip, which provides the ability to rapidly create
cells and blocks for applications including random logic, standard cell blocks
and library elements. By automating a significant portion of the layout process,
FastChip enables designers to significantly reduce overall design time. In
addition, it allows them to perform extensive "what-if" analysis with design
variables like placement and aspect ratios that have significant bearing on
performance.

         Cadence's Ensemble(TM) product family provides advanced place and route
("P&R") solutions for gate, cell, block and mixed designs. A significant number
of major ASIC vendors use Gate Ensemble(TM) as their internal P&R engine.
Cadence offers two products for cell based routing, Cell Ensemble(TM) and
Cell3(TM). Built on a channel-based routing architecture, Cell Ensemble(TM) is
finely tuned for two layer metal designs. For three layer metal and above,
Cell3(TM) is a widely-used solution. Cell3's(TM) innovative area-based
architecture is based on the industry's most advanced routing algorithms. For
block-based routing, the Company offers Block Ensemble(TM). Cadence's early-1996
introduction of Silicon Ensemble(TM) unveiled a fourth generation P&R system to
tackle today's increasingly challenging design problems. Based on Cadence
proprietary area-based architecture, Silicon Ensemble(TM) provides a
comprehensive solution for routing up designs that consist of a mix of cell and
gate-based approaches. In addition, Silicon Ensemble(TM) includes several
specialized routing engines to deal with specific design 

                                       3
<PAGE>   6
challenges like datapath, complex clock trees, crosstalk and low power. The
product family is rounded out with one of the industry's fastest placement
systems, QPlace(TM). Based on innovative quadratic algorithms, QPlace(TM) has
been rapidly accepted throughout the ASIC community.

         Cadence has long been an industry leader in physical verification based
on the overwhelming market adoption of the Company's Dracula(R) product family.
Physical verification provides the final check before products are released to
manufacturing. Thus, accuracy in the verification process is essential to
avoiding costly production runs of faulty parts. Dracula(R) has been the
industry's benchmark for accuracy which has been the key to its success. For
interactive verification, the Company's Diva(R) product line has also enjoyed
significant market success. In 1995, Cadence introduced Vampire(TM) as a
solution to next-generation verification design requirements. Vampire(TM)
provides advanced hierarchical design capability necessary to successfully
verify today's largest chips.

SYSTEM DESIGN PRODUCTS

         The Allegro(TM) product family is the foundation of Cadence's PCB
design. The Allegro(TM) line offers complete solutions for layout of standard
PCB, hybrid, MCM and advanced component packaging. Products which compliment the
Allegro(TM) line (DF/Signoise(TM) for signal integrity, DF/Thermax(TM) for
thermal, DF/Viable(TM) for reliability and DF/EMControl(TM) for electromagnetic
compliance) round out a suite of analysis tools for detecting potential
manufacturing problems. In 1995, the Company introduced BoardQuest(TM), a
breakthrough approach to system design planning. BoardQuest(TM) is specifically
tailored for the needs of high-speed designers, offering an advanced system to
accurately predict thermal, interconnect and electromagnetic effects early in
the design process.

         For analog designers, Cadence offers integrated solutions for analog,
mixed signal and microwave IC and system design. The Analog Artist(TM) series
provides a comprehensive set of simulation, layout and verification tools for
chip design. This product family features the Spectre(TM) high-speed circuit
simulation family of products. In 1994, Cadence introduced Spectre(TM)HDL, the
industry's first analog behavioral simulation system for analog and mixed-signal
applications. In 1995, the Company further expanded the product offering with
the introduction of Spectre(TM)RF, simulation technology utilized specifically
for the design of radio frequency applications. For analog system and board
level design, Cadence's Analog Workbench(TM) offers tools from top-down design
through board design. A key to the success of Analog Workbench(TM) has been the
extensive analog model libraries and advanced statistical analysis tools
available with the design environment.

ELECTRONIC SYSTEMS DESIGN AUTOMATION ("ESDA") PRODUCTS

         Cadence's Alta Group has developed an entirely new class of software
for top-down design known as Electronic Systems Design Automation ("ESDA"). ESDA
accelerates and enhances the early phases of system development. The Alta Group,
led by its Signal Processing Workbench ("SPW")(R) tool set is able to provide
customers with a higher level of design automation for a number of application
areas including wireless communications, networking and multi-media.

         ESDA is seen as a natural evolution of EDA that enables customers to
include product concept in the design environment. Alta's focus is on Virtual
Product Design, a new approach that starts with the creation of a product
prototype in software, what is called virtual prototype. Virtual prototyping
allows the designer to focus on what is needed for the product to be successful
as opposed to how the design is implemented.

         Alta's product offerings include a large applications library of design
blocks, a complete technology base and a visualization and analysis environment.
Once the design is conceptualized, Alta's products provide links to
implementation which include multiple capabilities that allow the design to be
passed downstream to ASIC and IC engineers.

MARKETING AND SALES

         As of March 1, 1996, Cadence had 869 employees engaged in field sales
and sales support, representing approximately 29% of its total work force. In
North America, Cadence uses a direct sales force consisting of sales people and
applications engineers to license its products. Cadence's sales force presents
Cadence and its products for licensing to prospective customers, while
applications engineers provide technical pre-sales as well as post-sales
support. Due to the complexity of EDA products, the selling cycle is generally
long, with three to six months being typical. Activities during this sales cycle
typically consist of a technical presentation, a product demonstration, a design
benchmark and often, an on-site customer evaluation of Cadence software.

         In Europe and Asia, Cadence markets and supports its products primarily
through 15 majority-owned subsidiaries. Cadence also serves its international
customers through distributors in various countries throughout Europe and
Asia/Pacific. Cadence licenses its IC products in Japan primarily though a
distributor, Innotech Corporation ("Innotech"). In 1995, 1994 and 1993, Innotech
accounted for 15%, 10% and 13% of total revenue, respectively. Cadence's systems
products are marketed in Japan through a majority-owned subsidiary.

         Revenue from international sources was $271.8 million, $221.5 million
and $183.6 million, or approximately 50%, 52% and 50% of total revenue for 1995,
1994 and 1993, respectively. (See Notes to Consolidated Financial Statements for
a summary of operations by geographic area.) Prices for international customers
are quoted from an international price list. The list is maintained in U.S.
dollars but reflects the higher cost of doing business outside the United
States. International customers are invoiced in U.S. dollars using current
exchange rates or the local currency.

         The Company enters into foreign currency forward contracts to hedge the
impact of foreign currency fluctuations. Though the Company attempts to reduce
the impact of foreign currency fluctuations, significant exchange rate movements
may have a material adverse impact on the Company's results of operations.

         Cadence is required to have United States Department of Commerce export
licenses for shipment of its products outside the United States. Although to
date Cadence has not encountered any material difficulty in obtaining these
licenses, any difficulty in obtaining necessary export licenses in the future
could have an adverse effect on revenue.

PRODUCT DEVELOPMENT AND ENGINEERING

         For the years 1995, 1994 and 1993, respectively, Cadence's investment
in research and development was $100.4 million, $88.2 million and $89.7 million
prior to capitalizing $11.8 million, $10.8 million and $15.2 million of software
development costs. Cadence began capitalizing certain of 

                                       5
<PAGE>   8
its software development costs in 1986 in accordance with Statement of Financial
Accounting Standards No. 86. See Notes to Consolidated Financial Statements for
a more complete description of Cadence's capitalization of certain software
development costs.

         Cadence is currently developing technology that it will introduce to
the EDA market in 1996 and beyond. Among the primary areas that Cadence is
addressing are the design of silicon devices in the deep sub-micron range,
high-speed board design, architectural-level design and high-performance logic
verification technology.

         Customer Partnerships

         Cadence has established close working relationships with a number of
semiconductor manufacturers and electronic system companies based on a business
partnership model that has become a central business model for the Company. To
ensure that research and development activities are properly prioritized and
also that finished products meet customers' needs, major new product
developments often times begin after collaboration with a Cadence
customer/partner.

         These technology partnerships allow Cadence to work with customers'
designers in defining and developing state-of-the-art solutions for current and
emerging design approaches. Through an engineer exchange program, customers will
often work on-site at Cadence facilities, giving Cadence valuable insight into
customer product planning. Product development partnerships are generally
directed at the development and refinement of specific tools.

         University Programs

         Cadence supports EDA research by sharing its design automation
technology and expertise with universities. More than 500 universities worldwide
participate, including the University of California at Berkeley, Duke
University, the Massachusetts Institute of Technology and Stanford University.
Certain faculty members from the University of California at Berkeley,
considered to be a leading university for IC design software research, have
served as consultants to Cadence since its inception. These consultants have
helped Cadence to stay abreast of the latest developments and directions in the
rapidly changing IC design software industry.

         Next-Generation Technological Development

         Cadence's advanced research and development group, Cadence Berkeley
Laboratories, is committed to new technological development. This group is
chartered with identifying and developing prototype technologies in emerging
design areas which will offer substantially improved alternatives to current EDA
solutions. Cadence Berkeley Laboratories is Cadence's commitment that it is
continuing to develop leading-edge technology.

COMPETITION

         The Company faces intense competition in the EDA product market, which
continues to be characterized by aggressive pricing practices and new market
entrants. The Company competes with other companies, including Mentor Graphics
Corp., Synopsys, Inc., Viewlogic Systems, Inc. and Zuken-Redac that sell one or
more competing products and with potential customers' internal EDA software
development groups. Some of the Company's competitors may have substantially
greater financial, marketing and technological resources than the Company. There
can be no assurance that the Company will be able to compete successfully.

         Because the EDA industry is labor intensive rather than capital
intensive, the number of potential competitors to the Company is significant. A
potential competitor who possesses the necessary knowledge of electronic circuit
and systems design, production and operation could develop EDA tools using a
moderately priced computer workstation and bring such tools to market quickly.
If such an EDA software tool were to surpass the technology of a tool of the
Company, the attention of customers might rapidly shift to the new tool,
resulting in a precipitous decline in the sales of the Company's comparable
product.

         The Company has in the past discounted EDA product prices where deemed
necessary for competitive reasons or in connection with volume purchase
agreements with major customers. In the 

                                       6
<PAGE>   9
past, discounts of up to 60% of the list prices of the EDA products have been
given. Although the Company is striving to reduce discounts, it recognizes that
it may be required to discount EDA product prices under similar circumstances in
the future.

         Cadence cooperates with other design automation vendors to deliver
full-scope technology to its customers. Through Cadence's Connections Program,
customers can more easily integrate Cadence products and technologies with other
companies' products and technologies. This provides customers with the
flexibility to mix and match third-party and proprietary tools to specifically
meet their design automation needs. Today over 100 companies have integrated
their tools with Cadence's software.

         The major advantages of Cadence products over its competitors products
include higher performance capabilities, enhanced features, and more efficient
design methodologies through integration of electrical and physical design
tools. Cadence's commitment to industry standard hardware platforms, operating
systems and networking protocols allows users to configure an open design
environment tailored to their specific needs. As design needs grow, a Cadence
design environment can be expanded to include additional Cadence tools or
third-party tools.

         Currently, no major EDA software supplier or consulting organization
has demonstrated offerings for the electronic engineering market in as
comprehensive of a fashion as Cadence. The Company believes that the
infrastructure it has put in place over the past three years has given it a
significant lead over other companies that might attempt to emulate its services
business model.

PROPRIETARY TECHNOLOGY

         Cadence believes that its continued success lies, in part, in its
employees and the combined knowledge, ability and experience they collectively
bring and the abilities of its management team to focus that energy on achieving
the Company's goals and objectives.

         To help focus its energies on the engineering side and to stress the
importance of new technology development to Cadence, the Company has an
aggressive invention program which is actively conveyed to the Company's many
designers, developers, and other engineering personnel throughout the world. The
Company has a very competitive employee invention compensation awards program to
promote the disclosure of inventive subject matter for patent protection. Given
that name recognition in the community is also very important to Cadence and its
engineers, the Company also has an aggressive author incentive awards program to
encourage the publication of some of its developments pioneered by the
engineering community.

         Cadence primarily relies on licensing, non-disclosure, proprietary
rights, and other forms of agreements to secure its rights to its proprietary
technology. Cadence's products are generally licensed to end-users on a "right
to use" basis pursuant, typically, to a non-transferable license grant which
restricts the use of its products to designated seats at designated sites for
the customer's internal design purposes only. Cadence's various agreements
prohibit a customer from disclosing the proprietary information contained in the
Company's products to any other third person or entity. Although Cadence has
taken various technical measures in the form of keys, time-driven locks, and
other software and hardware mechanisms to protect its technology, Cadence
recognizes that it may very well be technologically feasible for competitors of
Cadence to copy aspects of the Company's licensed products in violation of
agreements and Cadence's proprietary rights. Cadence fully intends to remain
aggressive with respect to protecting its proprietary technology and will seek
civil and criminal penalties along with any available equitable relief against
those who would take or attempt to take or otherwise misappropriate its
proprietary technology and other confidential information.

         Cadence also relies on a combination of patent, copyright, and
tradesecret laws and other traditional intellectual property protection
mechanisms. In 1995, Cadence was granted five new patents for a total of 16
issuances and was allowed four additional patents. Further, Cadence has in
excess of 25 patent applications pending with more in process. Cadence has an
aggressive trademark program extending world-wide and common law rights to
protect its good name associated with marks on its goods and services. In 1995,
Cadence filed in excess of 35 new trademark applications. In addition, Cadence
has also sought federal copyright protection for certain of its products.
Cadence does not

                                       7
<PAGE>   10
believe that any of its technology infringes that of others nor does Cadence
believe that any of its trademarks infringe the marks of others.

         Although Cadence recognizes that technology development and the
protection of such technology is vitally important to maintaining its place
within the EDA industry, because of the rapid pace of technological change in
the industry, it may very well be that inherent factors such as the knowledge,
ability, and experience of the Company's personnel, along with name recognition,
and various ongoing product support activities may prove to be more significant
in maintaining the Company's competitive edge.

MANUFACTURING

         Cadence's software production operations consist of configuring the
proper version of a product, recording it on magnetic tape or CD-ROM, and
producing customer unique access keys which allow customers to use purchased
products. User manuals and other documentation are generally available on
CD-ROM, but are occasionally supplied in hard copy format. Shipments are
generally made within two weeks of receiving an order.

EMPLOYEES

         As of March 1, 1996, Cadence employed 3,028 persons, including 1,778 in
sales, marketing, support and manufacturing activities, 997 in product
development and 253 in management, administration and finance. None of Cadence's
employees are represented by a labor union, and Cadence has experienced no work
stoppages. Cadence believes that its employee relations are good.

         Competition in recruiting of personnel in the software industry is
intense. Cadence believes that its future success will depend in part on its
continued ability to recruit and retain highly skilled management, marketing and
technical personnel.

ITEM 2.   PROPERTIES

         The Company's headquarters are located in San Jose, California, and the
Company owns the related land and buildings. The total square footage of the
buildings comprising the Company's headquarters is approximately 515,000. In
addition, the Company also owns undeveloped land adjacent to the Company's
headquarters, available for future expansion.

         In addition to the Company's headquarters, the Company continues to
lease three buildings with approximately 209,000 square feet in San Jose,
California at an annual rate of approximately $2.9 million. The leases related
to approximately 129,000 square feet expire in March 1998, and the remaining
lease expires in February 1999. Approximately 112,000 of the square footage of
these facilities has been sublet and the balance remains available for sublet.

         Cadence leases additional facilities for its sales offices in the
United States and various foreign countries, and research and development
facilities in San Diego, Santa Cruz and Berkeley, California, Lawrence, Kansas,
United Kingdom, France, Taiwan and India at an aggregate annual rental of
approximately $8.1 million. Cadence also leases approximately 100,000 square
feet of facilities in Chelmsford, Massachusetts for its east coast operations
and approximately 70,000 square feet in Sunnyvale, California for its Alta Group
operations at a combined annual rate of approximately $1.0 million.

         Cadence also leases approximately 83,000 square feet in a building in
Beaverton, Oregon, at a current annual rental of approximately $.7 million,
which houses manufacturing, engineering, marketing and administrative operations
for its IMS subsidiary and a regional software sales office.

         Cadence believes that these facilities and the undeveloped land
adjacent to its current headquarters are adequate for its current needs and that
suitable additional or substitute space will be available as needed to
accommodate expansion of the Company's operations.

ITEM 3.   LEGAL PROCEEDINGS

         The Company is involved in various disputes and litigation matters
which have arisen in the ordinary course of business. These include disputes and
lawsuits related to intellectual property, contract law and employee relations
matters.

         The Company filed a complaint in the United States District Court for
the Northern District of California on December 6, 1995 against Avant!
Corporation (formerly known as ArcSys, Inc., "Avant!") and certain of its
employees for misappropriation of trade secrets, copyright infringement,
conspiracy and other illegalities.

         On January 16, 1996, Avant! filed various counterclaims against the
Company and the Company's President and CEO, alleging, inter alia, that the
Company and its President and CEO had cooperated with the Santa Clara County
District Attorney and initiated and pursued its complaint against Avant! for
anti competitive reasons, engaged in wrongful activity in an attempt to
manipulate Avant!'s stock price and utilized certain pricing policies and other
acts to unfairly compete against Avant! in the marketplace. The counterclaim
also alleges that certain unspecified Company insiders engaged in illegal
insider trading with respect to Avant!'s stock. The Company and its President
and CEO believe that each has meritorious defenses to Avant!'s claims, and each
intends to defend such action vigorously.

         Management believes that the ultimate resolution of the disputes and
litigation matters discussed above will not have a material adverse impact on
the Company's financial position or results of operations.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

         EXCEPT FOR THE HISTORICAL INFORMATION CONTAINED HEREIN, THE FOLLOWING
DISCUSSION CONTAINS FORWARD LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE
DISCUSSED HEREIN. FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES
INCLUDE, BUT ARE NOT LIMITED TO, THOSE DISCUSSED BELOW IN FACTORS THAT MAY
AFFECT FUTURE RESULTS.

OVERVIEW

         Cadence Design Systems, Inc. (the "Company") develops, markets and
supports electronic design automation ("EDA") software products and services
that automate, enhance and accelerate the design and verification of integrated
circuits ("ICs") and electronic systems. The Company combines its technology
with services to help optimize its customers' product development processes. The
Company's customers and target markets include computer manufacturers, consumer
electronics companies, industrial electronics companies, semiconductor
manufacturers, ASIC foundries and telecommunications companies throughout the
world.

         In July 1995, the Company and its wholly-owned subsidiary, Integrated
Measurement Systems, Inc. ("IMS") sold to the public approximately 3.0 million
shares of common stock, of which approximately 2.6 million shares were sold by
the Company as the sole selling stockholder of IMS and .4 million shares were
sold by IMS. As a result of the offering and sale of shares by the Company, the
Company's ownership interest in IMS decreased to approximately 55%. However, as
the Company remains the majority stockholder, the consolidated financial
statements of the Company for all periods presented include the accounts of IMS
after elimination of intercompany accounts and transactions and minority
interest adjustments.

         In August 1994, the Company acquired the business and certain assets of
Redwood Design Automation, Inc. ("Redwood"). Redwood developed, marketed and
supported advanced software tools for electronic systems design. The acquisition
was accounted for as a purchase, and accordingly, the results of Redwood from
the date of the acquisition forward have been recorded in the Company's
consolidated financial statements. In connection with the acquisition, the
Company recorded a one-time charge to operations of $4.7 million for the
write-off of in-process research and development that had not reached
technological feasibility and, in management's opinion, had no probable
alternative future use. The Redwood business is now a part of the Company's Alta
Group.

         In June 1993, the Company acquired the business and certain assets of
Comdisco Systems, Inc. ("Comdisco"), a subsidiary of Comdisco, Inc. The Comdisco
business involves the development, marketing and support of digital signal
processing software products in the electronic systems design area. The
acquisition was accounted for as a purchase and accordingly, the results of
Comdisco from the date of the acquisition forward have been recorded in the
Company's consolidated financial statements. The Comdisco business is now a part
of the Company's Alta Group.

         In December 1993, the Company sold its Automated Systems ("ASI")
division. The operating results of ASI have been reported as a disposal of a
division and are included as an unusual item within operating expenses in the
consolidated statements of income for all years presented. The loss on disposal
of approximately $6.0 million is classified in other income (expense) in the
1993 statement of income.

</TABLE>

         In 1995, strong demand for the Company's products and services
generated a 28% increase in revenues as compared to the prior year. Revenue from
international sources was approximately $271.8 million, $221.5 million and
$183.6 million or, 50%, 52% and 50% of total revenue for 1995, 1994 and 1993,
respectively. In 1995, domestic and international revenue increased 33% and 23%,
respectively, following increases of 12% and 21% in 1994. The higher percentage
increase in domestic revenue in 1995 as compared to international revenue was
primarily attributable to an increase in domestic service revenue in 1995 as
compared to 1994. In addition, $11.7 million of the $50.3 million increase in
international revenue for the year ended December 30, 1995 was attributable to
the favorable impact on revenue of foreign exchange rates as the result of the
strengthening of certain foreign currencies in relation to the U.S. dollar as
compared to 1994.

         The increase in product revenue in 1995 reflected increased market
acceptance of the Company's products which enable customers to meet complex
design challenges, such as deep submicron IC design and high-speed board design.
This was exemplified by increased sales volume of its IC, automated test
engineering ("ATE"), top-down design ("HDL") and Alta Group's systems design
products. The Company's ATE, HDL and Alta Group product offerings also led the
increase in 1994 product revenue as compared to 1993. The 1994 increase in Alta
Group product revenue was partly due to 1994 including a full year of revenue
related to the Comdisco business as compared to 1993 which included only revenue
from the date of acquisition forward.

         The increase in service revenue was the result of significant demand
for the Company's service offerings which provide a complete range of solutions
to address the product development needs of its customers. The 1995 increase in
service revenue was driven by an outsourcing agreement with Unisys Corporation
("Unisys") to assume a substantial portion of Unisys' internal silicon design
operation. This five-year agreement was signed in the first quarter of 1995 for
a total contract value of at least $75 million.

         The increases in maintenance revenue were attributable to an increase
in the Company's installed base of products as well as the Company's continuing
success at obtaining customer maintenance renewals.

</TABLE>

         Cost of product revenue includes costs of production personnel,
packaging and documentation, amortization of capitalized software development
costs and costs of the Company's ATE hardware business. The decrease in cost of
product in absolute dollars and as a percentage of product revenue in 1995 as
compared to 1994 was primarily due to productivity improvements in the software
release and production process and reduction in printing and manufacturing
expenses due to decreased demand for manuals, partly offset by increased cost of
revenue associated with its ATE products resulting from higher product demand.

         Cost of service revenue includes personnel and related costs associated
with providing services to customers and the infrastructure to manage a services
organization, as well as costs to recruit, develop and retain service
professionals. Cost of service in absolute dollars has increased each year since
1993 due to the development of this line of business. The increase in cost of
service from 1994 to 1995 was also due to additional costs associated with the
transfer to the Company of former employees of Unisys pursuant to the
outsourcing agreement signed in the first quarter of 1995. As part of the Unisys
outsourcing agreement, the Company retained approximately 180 hardware and
software designers and acquired fixed assets and certain intangibles. While
primarily focusing on serving the needs of Unisys, the design and service
resources acquired by the Company are also being used to support other
customers' design needs. Service gross margins could continue to be adversely
affected until the design and service resources acquired from Unisys are more
fully utilized through additional revenue contracts. Additionally, the cost of
integrating new service professionals performing a growing number of service
offerings will also put pressure on service gross margins until operating
efficiencies are obtained.

         Cost of maintenance revenue includes the cost of customer services such
as hot-line and on-site support and the production cost of the maintenance
renewal process. The increase in cost of maintenance in absolute dollars from
1994 to 1995 was principally due to additional costs necessary to support a
larger installed base. The decrease in cost of maintenance revenue from 1993 to
1994 was primarily due to the continued streamlining of the maintenance renewal
process.

</TABLE>

MARKETING AND SALES

         Marketing and sales expenses grew from 1994 to 1995 due to an
additional $28.2 million of employee related costs resulting from increased
headcount, a higher volume of pre-sales activities and increased commissions and
sales incentives. Of these increased expenses, $5.1 million was attributable to
the effect of the strengthening of certain foreign currencies in relation to the
U.S. dollar. These increases were offset by approximately $6.0 million of
decreased facilities costs. The increase in 1994 as compared to 1993 was the
result of increased costs of $4.7 million related to the Alta operations which
were offset by cost reductions in other areas. As a percentage of total revenue,
sales and marketing expenses were higher in 1993 due to lower revenue levels.

RESEARCH AND DEVELOPMENT

         The Company's investment in research and development, prior to the
reduction for capitalization of software development costs, was $100.4 million,
$88.2 million and $89.7 million for 1995, 1994 and 1993, respectively,
representing 18%, 21% and 24% of total revenue. The increase of $12.2 million
from 1994 as compared to 1995 was primarily due to personnel costs of $11.0
million associated with increased headcount and incentive compensation and $1.6
million of higher consulting costs, offset by decreased facilities costs. The
decrease in 1994 as compared to 1993 was due to lower occupancy costs of $2.5
million and decreased capital equipment costs of $1.5 million offset by
increased costs of $2.4 million related to the Alta Group. The Company
capitalized approximately $11.8 million, $10.8 million and $15.2 million of
software development costs in the years 1995, 1994 and 1993, respectively, which
represented approximately 12%, 12% and 17% of total research and development
expenditures made in those years. The amount of capitalized software development
costs in any given period may vary depending on the exact nature of the
development performed.

GENERAL AND ADMINISTRATIVE

         The decrease in general and administrative costs as a percentage of
revenue from 1993 to 1995 was primarily attributable to revenue growing at a
faster rate than costs. The increase in absolute costs of $.7 million in 1995
was the result of $1.1 million of additional information system costs and $.7
million of additional legal expenses. These costs were offset by reductions in
employee-related costs, facilities costs and bad debt expense. The 1994 increase
in general and administrative costs was due to higher employee-related costs and
operations of the Alta Group totaling $2.5 million offset by cost savings of
$1.3 million resulting from lower facility costs.

</TABLE>

UNUSUAL ITEMS

         The unusual items in 1994 included costs of $4.7 million related to the
1994 third quarter write-off of in-process research and development associated
with the Redwood acquisition as Redwood's development efforts had not reached
technological feasibility and, in management's opinion, had no probable
alternative future use. Also included in the 1994 unusual items was a $10.0
million provision for settlement of litigation. In April 1994, the Company
entered into agreements to settle two class action lawsuits for a combined
settlement of $16.5 million, of which approximately $7.5 million was covered by
the Company's insurance carriers. Reflected in the statement of income in 1994
was the net settlement cost of approximately $9.0 million plus approximately
$1.0 million for related legal costs.

         Restructuring costs of $13.5 million associated with a planned
restructure of certain areas of sales, operations and administration due to
business conditions were recorded as an unusual item in March 1993. The
restructuring charge primarily reflected costs associated with employee
terminations, excess facilities and the write-off of purchased software and
intangibles arising from required adjustments to the Company's cost structure
necessitated by lower revenue levels. Also included in the restructuring charge
was an additional provision for doubtful accounts and the write-off of certain
software development costs resulting from changes in the Company's systems
product strategy. In December 1993, the Company sold its ASI division,
therefore, also included in unusual items for 1993 was the division's loss from
operations of $6.2 million.

OTHER INCOME AND EXPENSE

         Interest income was $4.9 million, $3.3 million and $3.2 million for
1995, 1994 and 1993, respectively. The increase in 1995 is primarily due to
increased earnings on cash investments resulting from higher interest rates.
Interest expense was $2.2 million, $1.0 million and $.7 million for 1995, 1994
and 1993, respectively. The increase in interest expense in 1995 as compared to
1994 and in 1994 as compared to 1993 was due to an increase in notes payable
related to the purchase of corporate facilities in the first and fourth quarters
of 1994. The note payable related to the first facility purchase was paid in
full in May 1994, and the note payable related to the second facility purchase
was paid in full in October 1995. Included in 1995 other income was an $18.9
million gain on the sale of approximately 45% of the stock of IMS, a previously
wholly-owned subsidiary, in an initial public offering. In 1994, other income
included a $4.2 million gain related to the sale of an equity investment. A $6.0
million loss on the disposal of the Company's ASI division was included in 1993
other expense.

</TABLE>

         As of December 30, 1995, the Company had gross deferred tax assets of
approximately $62.6 million against which the Company had recorded a valuation
allowance of $47.8 million, resulting in net deferred tax assets of $14.8
million. A significant portion of the net operating loss and credit
carryforwards which created the deferred tax assets was generated by acquired
companies prior to their merger with the Company and by restructuring charges
recorded as a result of these mergers. Approximately $34.2 million of these
deferred tax assets will affect equity and intangibles and will not be available
to offset future provisions for income taxes. Realization of the net deferred
tax assets of $14.8 million is dependent on generating sufficient taxable income
prior to the expiration of the loss and tax credit carryforwards. Although
realization is not assured, management believes that it is more likely than not
that the net deferred tax assets of $14.8 million will be realized. The amount
of the net deferred

                                       16
<PAGE>   19
tax assets considered realizable, however, could be reduced or increased in the
near term if actual facts, including the estimate of future taxable income,
differ from those estimated.

         The increase in the 1995 tax rate as compared to 1994 was attributable
to an increase in foreign earnings which are subject to a higher tax rate than
the U.S. tax rate, the related cost of repatriating these earnings and an
increase in state income taxes. The 1994 effective tax rate reflected a
reduction in the valuation allowance primarily from the utilization of net
operating losses generated in prior years. In 1993, the Company's tax provision
was zero as a result of the operating loss in 1993 and the recording of the
benefit of certain foreign withholding and income taxes. The Company anticipates
that its effective tax rate will increase to approximately 33% in 1996.

LIQUIDITY AND CAPITAL RESOURCES

         At December 30, 1995, the Company's principal sources of liquidity
consisted of $96.6 million of cash and cash investments and short-term
investments as compared to $96.9 million and $92.8 million at December 31, 1994
and 1993, respectively. The Company was able to maintain its cash position while
repurchasing $163.9 million and $95.1 million of treasury stock and repaying
notes payable and long-term debt totaling $26.5 million and $29.2 million in
1995 and 1994, respectively.

         Cash generated from operating activities increased $42.7 million in
1995 and $57.2 million in 1994. The 1995 increase was driven primarily by higher
net income and increases in accrued liabilities and payables and deferred
revenue, offset by increases in accounts receivable and prepaid expenses. The
increase in 1994 as compared to 1993 was primarily the result of increases in
net income and deferred revenue.

         Working capital at December 30, 1995 was $6.5 million compared with
$27.5 million at December 31, 1994. The primary reasons for the decrease in 1995
as compared to 1994 were increases in deferred revenue of $31.2 million and
current payables and accrued liabilities of $29.7 million, offset by a decrease
in notes payable of $24.9 million and an increase in accounts receivable of $9.9
million. The increase in deferred revenue was attributable to increased
maintenance renewals and an increase in deferred product revenue deferred in
accordance with the American Institute of Certified Public Accountants Statement
of Position 91-1 entitled "Software Revenue Recognition." The increase in
current payables and accrued liabilities was due to increased commissions,
incentive bonuses and income taxes in 1995. Notes payable decreased in 1995 as
the Company repaid a $23.7 million secured loan assumed as part of a 1994
purchase of corporate facilities. Although accounts receivable increased as a
result of increased revenue in 1995 as compared to 1994, days sales outstanding
decreased from 58 days at December 1994 to 49 days at December 1995 due to
improved collection efforts.

         In addition to its short-term investments, the Company's primary
investing activities were the purchase of property, plant and equipment and the
capitalization of software development costs, which combined, represented $40.2
million, $26.0 million and $33.7 million of cash used for investing activities
in 1995, 1994 and 1993, respectively. In 1995, the Company also generated $29.9
million from the sale of 3.0 million shares of IMS stock in an initial public
offering.

         The Company has an authorized stock repurchase program. In total, as of
December 30, 1995, the Company had authorized the repurchase of 34.1 million
shares, of which approximately 26.8 million shares had been repurchased. The
Company repurchases common stock in part to satisfy estimated requirements for
shares to be issued under the Company's employee stock option and stock purchase
plans as well as in connection with acquisitions. Past repurchase activity
should not be considered an indicator of future repurchases.

         Since 1994, as part of its authorized repurchase program, the Company
has sold 10.1 million put warrants through private placements. As of December
30, 1995, 7.5 million of these warrants had expired out of the money. The
remaining outstanding 2.6 million warrants entitle the holder to sell one share
of common stock to the Company on a specified date and at a specified price
ranging from $24.09 to $33.03 per share. Additionally, during this same period,
the Company purchased approximately 7.6 million call options that entitle the
Company to buy on a specified date one share of common stock at a specified
price. As of December 30, 1995, the Company had repurchased 5.6 million common
shares

                                       17
<PAGE>   20
pursuant to the exercise of call options for $72.8 million. The remaining 2.0
million outstanding call options range in price from $24.17 to $33.37 per share.

         The Company has the right to settle the put warrants with stock, cash
or a combination of stock and cash equal to the difference between the exercise
price and the fair value at the date of exercise. Settlement of the put warrants
with stock could cause the Company to issue a substantial number of shares,
depending on the amounts of the repurchase obligations and the per share fair
value of the Company's common stock at the time of exercise. In addition,
settlement of put warrants in stock or cash could lead to the disposition by put
warrant holders of shares of the Company's common stock that such holders may
have accumulated in anticipation of the exercise of the put warrants or call
options, which may impact the price of the Company's common stock.

         As discussed above, financing activities in 1995, 1994 and 1993 related
principally to the Company's stock repurchase program and payments of notes
payable. The Company's stock repurchases included open market and private
purchases, and as discussed above, exercise of call options. In 1995, the
Company repurchased a warrant previously issued in connection with an
acquisition, equivalent to approximately 1.8 million shares of the Company's
common stock for a total cost of $17.2 million. The sale of common stock
primarily to the Company's employees as part of its employee benefit plans
generated $26.5 million, $13.5 million and $4.3 million in cash during 1995,
1994 and 1993, respectively.

         Anticipated cash requirements for fiscal 1996 include the purchase of
treasury stock through the exercise of the Company's call options and in the
open market. The Company has the right to purchase approximately 2.0 million
shares through the exercise of call options in 1996 at a cost of approximately
$52.3 million. As part of its overall investment strategy, the Company has
committed to participate in a venture capital partnership as a limited partner.
The Company's total investment of $25.0 million will be made over the next three
to four years. Other cash requirements include contemplated additions of capital
equipment of approximately $35.0 million.

         The Company anticipates that current cash and short-term investment
balances, cash flows from operations and short and long-term borrowing
capabilities will be sufficient to meet its working capital and capital
expenditure requirements on a short and long-term basis. The Company's majority
owned subsidiary, IMS, has a $10.0 million bank line of credit. The Company is
currently in negotiations with various lenders regarding a line of credit, but
there can be no assurance that mutually acceptable terms can be reached and that
the Company will have a line of credit available in the short-term. To the
extent that the Company does not utilize bank lines of credit or borrowings to
fund its operations on a short-term basis, the Company may continue to reduce
its current cash and may experience future working capital deficits on a
short-term basis.

FACTORS THAT MAY AFFECT FUTURE RESULTS

         The Company competes in the highly competitive EDA market which
continues to be characterized by aggressive pricing practices, rapid
technological change and new market entrants. The Company's success is dependent
upon its ability to develop innovative, cost-competitive EDA software products
and services, and to bring them to market in a timely manner.

         The Company's future operating results are dependent on the Company's
ability to successfully implement its strategy to help its customers meet their
business objectives by optimizing their product development processes. The
Company accomplishes this through a combination of technology and services.
Inherent in implementing this strategy are a number of risks that the Company
must manage and that could affect its future operating results. These risks
include the ability to successfully recruit, train and retain its skilled
service professionals and the ability to profitably deliver services that meet
customer expectations. Growth of the service business is constrained by the
Company's ability to hire and train service professionals to keep pace with
demand. The Company's profitability could be adversely affected if it is unable
to develop its services business as expected.

         It is anticipated that international revenue will continue to
constitute a significant portion of total revenue. International revenues are
subject to certain additional risks normally associated with international
operations, including, among others, adoption and expansion of government trade

                                       18
<PAGE>   21
restrictions, volatile foreign exchange rates, currency conversion risks,
limitations on repatriation of earnings and reduced protection of intellectual
property rights.

         The Company enters into foreign currency forward contracts to hedge the
impact of foreign currency fluctuations. Though the Company attempts to reduce
the impact of foreign currency fluctuations, significant exchange rate movements
may have a material adverse impact on the Company's results of operations.

         The Company's operating expenses are partially based on its
expectations of future revenue. The Company's results of operations may be
adversely affected if revenue does not materialize in a quarter as expected.
Since expense levels are usually committed in advance of revenues and because
only a small portion of expenses vary with revenue, the Company's operating
results may be impacted significantly by lower revenue. Based on the Company's
operating history and factors that may cause fluctuations in the quarterly
results, quarter to quarter comparisons should not be relied upon as indicators
of future performance. Although the Company's revenues are not generally
seasonal in nature, the Company has experienced decreases in first quarter
revenue versus the preceding fourth quarter which is believed to result
primarily from the capital purchase cycle of the Company's customers.

         Due to the foregoing, as well as other factors, past financial
performance should not be considered an indicator of future performance. In
addition, the Company's participation in a highly dynamic industry often results
in significant volatility of the Company's common stock price. Any change in
revenues or operating results below levels expected by securities analysts for
the Company or its competitors, and the timing of the announcement of such
shortfalls, could have an immediate and significant adverse effect on the
trading price of the Company's common stock in any given period.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

TO THE STOCKHOLDERS AND BOARD OF DIRECTORS OF CADENCE DESIGN SYSTEMS, INC:

We have audited the accompanying consolidated balance sheets of Cadence Design
Systems, Inc. (a Delaware corporation) and subsidiaries as of December 30, 1995
and December 31, 1994, and the related consolidated statements of income,
stockholders' equity and cash flows for each of the three years in the period
ended December 30, 1995. These financial statements and the schedule referred to
below are the responsibility of the Company's management. Our responsibility is
to express an opinion on these financial statements and schedule based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Cadence Design Systems, Inc.
and subsidiaries as of December 30, 1995 and December 31, 1994, and the results
of their operations and their cash flows for each of the three years in the
period ended December 30, 1995, in conformity with generally accepted accounting
principles.

Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The schedule listed in Item 14. (a) 2. is presented
for purposes of complying with the Securities and Exchange Commission's rules
and is not part of the basic financial statements. This schedule has been
subjected to the auditing procedures applied in the audit of the basic financial
statements and, in our opinion, fairly states in all material respects the
financial data required to be set forth therein in relation to the basic
financial statements taken as a whole.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION
         The consolidated financial statements include the accounts of the
Company and its majority-owned subsidiaries after elimination of intercompany
accounts and transactions. The functional currency of all of the Company's
foreign subsidiaries is the local currency. Gains and losses resulting from the
translation of the subsidiaries' financial statements are reported as a separate
component of stockholders' equity. Effective December 31, 1994, the Company's
fiscal year end is the Saturday closest to December 31.

         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.

         Certain prior year financial statement balances have been reclassified
to conform to the 1995 presentation.

         REVENUE RECOGNITION
         Product revenue consists principally of revenue earned under software
license agreements and is generally recognized when the software has been
shipped and there are no significant obligations remaining. Revenue from
subscription license agreements which include software and maintenance is
deferred and recognized ratably over the term of the subscription period. Test
equipment revenue is recognized upon shipment of the test equipment.

         Service revenue consists primarily of revenues received for performing
product design development and process improvement, and education and
assimilation of software products into the customers' product development
process. Service revenue is generally recognized as the services are performed
or on the percentage of completion method of accounting, depending upon the
nature of the project. Under the percentage of completion method, revenue
recognized is that portion of the total contract price that costs expended to
date bears to the anticipated final total costs based on current estimates of
the costs to complete the project. If the total estimated costs to complete a
project exceed the total contract amount, indicating a loss, the entire
anticipated loss would be recognized currently.

         Maintenance revenue consists of fees for providing system updates, user
documentation and technical support for software products. Maintenance revenue
is recognized ratably over the term of the agreement.

         In 1995, 1994 and 1993, one customer (a distributor), which also holds
a minority interest in a subsidiary of the Company, accounted for 15%, 10% and
13% of total revenue, respectively.

        Outstanding trade accounts receivable from this related party were
approximately $5.4 million and $3.7 million at December 30, 1995 and December
31, 1994, respectively.

         SOFTWARE DEVELOPMENT COSTS AND PURCHASED SOFTWARE AND INTANGIBLES
         The Company capitalizes software development costs in compliance with
Statement of Financial Accounting Standards ("SFAS") No. 86, "Accounting for the
Costs of Computer Software to be Sold, Leased or Otherwise Marketed."
Capitalization of software development costs begins upon the establishment of
technological feasibility of the product. The establishment of technological
feasibility and the ongoing assessment of the recoverability of these costs
requires considerable judgment by management with respect to certain external
factors, but not limited to, anticipated future gross product revenue, estimated
economic life and changes in software and hardware technology. Amortization of
capitalized software development costs begins when the products are available
for general release to customers and is generally computed on a straight-line
basis over three years or, if less, the remaining estimated economic life of the
product. Purchased software and intangibles are amortized on a straight-line
basis over the remaining estimated economic life of the underlying product (two
to seven years). It is reasonably possible that the estimates of anticipated
future gross revenues, the remaining estimated economic life of the products, or
both could differ from those used to assess the recoverability of these costs
and result in a write-down of the carrying amount or a shortened life of the
costs in the near term.

         In the accompanying statements of income, amortization is included in
cost of product for capitalized software development costs and in either cost of
product or cost of service for purchased software costs, as determined by the
nature of the underlying transaction. In total, amortization of capitalized and
purchased software and intangibles amounted to approximately $19.7 million,
$20.2 million and $17.1 million for 1995, 1994 and 1993, respectively. The
Company wrote off $.8 million of purchased software in 1995 and $1.5 million of
capitalized software in 1993 for projects discontinued during the year.

         NET INCOME (LOSS) PER SHARE
         Net income per share for each period is calculated by dividing net
income by the weighted average shares of common stock and common stock
equivalents outstanding during the period (calculated using the modified
treasury stock method). Common stock equivalents consist of dilutive shares
issuable upon the exercise of outstanding common stock options and warrants. Net
loss per share is calculated by dividing net loss by the weighted average number
of common shares outstanding. Fully diluted net income (loss) per share is
substantially the same as primary net income (loss) per share.

         CASH, CASH INVESTMENTS AND SHORT-TERM INVESTMENTS
         The Company considers all highly liquid debt instruments and
certificates of deposit with an original maturity of ninety days or less to be
cash investments. The Company classifies its investments in debt securities as
"held-to-maturity". Accordingly, these investments, which mature at various
dates through August 1996, are valued using the amortized cost method. The fair
value of the investments approximates amortized cost, and as such, the gross
unrealized holding gains and losses at December 30, 1995 and December 31, 1994
are not material. Short-term investments consisted of the following:

         Property, plant and equipment is stated at cost. Depreciation and
amortization are provided over the following estimated useful lives, by the
straight-line method.

   Buildings                                 31 years
   Leasehold and building improvements       Shorter of the lease term or the
                                             estimated useful  life
   Equipment                                 3 - 6 years
   Furniture and fixtures                    3 - 5 years

         FINANCIAL INSTRUMENTS
         The Company has an authorized stock repurchase program. In total, as of
December 30, 1995, the Company had authorized the repurchase of 34.1 million
shares of which approximately 26.8 million shares had been repurchased. The
Company repurchases common stock in part to satisfy estimated requirements for
shares to be issued under the Company's employee stock option and stock purchase
plans as well as in connection with acquisitions.

         Since 1994, as part of its authorized repurchase program, the Company
sold 10.1 million put warrants through private placement. As of December 30,
1995, 7.5 million of these warrants had expired out of the money. The remaining
outstanding 2.6 million warrants entitle the holder to sell one share of common
stock to the Company on a specified date and at a specified price ranging from
$24.09 to $33.03 per share. Additionally, during this same period, the Company
purchased approximately 7.6 million call options that entitle the Company to buy
on a specified date one share of common stock at a specified price. As of
December 30, 1995, the Company had repurchased 5.6 million common shares
pursuant to the exercise of call options for $72.8 million. The remaining 2.0
million outstanding call options range in price from $24.17 to $33.37 per share.

         The Company has the right to settle the put warrants with stock, cash
or a combination of stock and cash equal to the difference between the exercise
price and the fair value at the date of exercise. Settlement of the put warrants
with stock could cause the Company to issue a substantial number of shares,
depending on the amounts of the repurchase obligations and the per share fair
value of the Company's common stock at the time of exercise. In addition,
settlement of put warrants in stock or cash could lead to the disposition by put
warrant holders of shares of the Company's common stock that such holders may
have accumulated in anticipation of the exercise of the put warrants or call
options, which may impact the price of the Company's common stock.

         At December 30, 1995, the fair value of these call options was
approximately $31.2 million and the fair value of the put warrants was
approximately $.9 million. The put warrants and call options outstanding at
December 30, 1995 are exercisable on various dates through April 1996. Fair
value of put warrants and call options was estimated by the Company's investment
bankers.

         At December 30, 1995, the Company had both the unconditional right and
the intent to settle these put warrants with stock, and therefore, no amount was
classified out of stockholders' equity in the accompanying balance sheet. The
effect of the exercise of these put warrants and call options is reported in
stockholders' equity.

         The Company enters into foreign currency forward exchange contracts
("forward contracts") to hedge the impact of foreign currency fluctuations. Due
to the short-term nature of these forward contracts, the unrealized gains and
losses were not material at December 30, 1995 and will be recorded when
realized. The estimated fair value for foreign exchange contracts is primarily
based on quoted market prices for the same or similar instruments, adjusted
where necessary for maturity differences. The estimated fair value at December
30, 1995 and December 31, 1994 was negligible. The notional amount of the
forward contracts was approximately $30.0 million at December 30, 1995. These
contracts expired on January 31, 1996.

         For certain of the Company's financial instruments, including cash and
cash investments, short-term investments and debt, the carrying amounts
approximate fair value due to their short-term nature.

                                       32

<PAGE>   35
         The estimated fair values discussed above may not be representative of
actual values that could have been realized as of year-end or that will be
realized in the future.

         CONCENTRATION OF CREDIT RISK
         Financial instruments which may potentially subject the Company to
concentrations of credit risk consist principally of cash investments,
short-term investments, accounts receivable, foreign exchange forward contracts,
and call options purchased in conjunction with its stock repurchase program. The
Company's investment policy limits investments to short-term, low-risk
instruments. Concentration of credit risk related to accounts receivable is
limited due to the varied customers comprising the Company's customer base and
their dispersion across geographies. Credit exposure related to the forward
contracts is limited to the unrealized gains on these contracts. Credit exposure
on call options is limited to the unrealized gains on the option contracts. All
financial instruments are executed with financial institutions with strong
credit ratings which minimizes risk of loss due to nonpayment. The Company has
not experienced any losses due to credit impairment related to its financial
instruments.

         NEW ACCOUNTING STANDARD
         In October 1995, the Financial Accounting Standards Board issued SFAS
No. 123, "Accounting for Stock Based Compensation" which will be effective for
the Company's 1996 fiscal year. SFAS No. 123 allows companies which have
stock-based compensation arrangements with employees to adopt a new fair-value
basis of accounting for stock options and other equity instruments, or to
continue to apply the existing accounting rules under Accounting Principles
Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees" but
with additional financial statement disclosure. The Company plans to continue to
account for stock-based compensation arrangements under APB Opinion No. 25, and
therefore does not anticipate SFAS No. 123 will have a material impact on its
financial position, results of operations or cash flows.

INTEGRATED MEASUREMENT SYSTEMS, INC. INITIAL PUBLIC OFFERING

         In July 1995, the Company and its wholly owned subsidiary, Integrated
Measurement Systems, Inc. ("IMS") sold to the public approximately 3.0 million
shares of common stock at $11 per share in a registered initial public offering.
Of these shares, approximately .4 million were sold by IMS and approximately 2.6
million were sold by the Company as the sole selling stockholder of IMS. The
sale generated net proceeds to the Company, after underwriting expenses,
discounts, commissions and other expenses, of approximately $26.6 million and a
pre-tax gain of approximately $18.9 million, which is reflected as other income
in the accompanying statement of income. The Company also recognized a $.7
million unrealized gain, net of taxes, which was recorded in stockholders'
equity. IMS received net proceeds of approximately $3.3 million. As a result of
the offering and sale of shares by the Company, the Company's ownership interest
in IMS decreased to approximately 55%. The minority interest liability of $10.6
million related to IMS is recorded in minority interest liability in the
accompanying December 30, 1995 balance sheet.

ACQUISITIONS

         REDWOOD DESIGN AUTOMATION

         In August 1994, the Company acquired the business and certain assets of
Redwood Design Automation, Inc. ("Redwood") for approximately .6 million shares
of the Company's common stock valued at $4.6 million. Prior to the acquisition
of Redwood, the Company advanced $1.8 million to Redwood which was not repaid.
Redwood was a development stage company formed to design, develop and market
software for use in electronic systems design. The acquisition was accounted for
as a purchase and accordingly, the results of Redwood from the date of
acquisition forward have been recorded in the Company's consolidated financial
statements. In connection with the acquisition, net intangibles of $6.8 million
were acquired, of which $4.7 million was reflected as a one-time charge to
operations for the write-off of in-process research and development that had not
reached technological feasibility and, in management's opinion, had no probable
alternative future use. This one-time charge was reflected in the Company's 1994
statement of income as an unusual item within operating expenses. The remaining
intangibles of $2.1 million are included in purchased software and intangibles
in the accompanying balance sheets and are being amortized over their useful
life of two years.

         In connection with the acquisition, net assets acquired were as follows

         REAL ESTATE PARTNERSHIPS

         In March 1994, the Company acquired all third-party interests in two
real estate partnerships in which it was a 46.5% and 80% limited partner,
respectively, for approximately $8.7 million in cash and the assumption of a
secured construction loan of approximately $23.5 million. The Company leased
buildings from one of the limited partnerships, and the second limited
partnership owned unencumbered land adjacent to the leased property. The Company
repaid the secured construction loan in May 1994.

         In October 1994, the Company acquired all third-party interests in a
third real estate partnership in which it was a 49% limited partner for
approximately $5.9 million in cash. The partnership owns

         PROVISION FOR SETTLEMENT OF LITIGATION

         In April 1994, the Company entered into agreements to settle two class
action lawsuits for a combined settlement of $16.5 million, of which
approximately $7.5 million was covered by the Company's insurance carriers.

         LOSS (INCOME) FROM OPERATIONS OF DISPOSED DIVISION

         In December 1993, the Company sold its Automated Systems ("ASI")
division. ASI was sold for a nominal amount of cash and future royalties. During
1994, ASI filed for Chapter 11 bankruptcy and in 1995, the royalty terms were
renegotiated. However, it is unknown if the Company will ultimately receive any
such royalties.

         In light of the nominal proceeds received, the sale of ASI resulted in
a loss on disposal of approximately $6.0 million. The loss was due principally
to the loss on the sale of the net operating assets, as well as amounts accrued
for estimated costs to be incurred in connection with the disposal. As of
December 30, 1995 and December 31, 1994, respectively, the Company had recorded
approximately $.9 million and $.9 million in accrued liabilities and
approximately $1.0 million and $1.1 million in other long-term liabilities for
liabilities associated with the disposed division.

         The Company had previously reported the operating results of ASI as a
discontinued operation in the statement of income. In connection with the filing
of a registration statement on Form S-3 to register common stock issued to the
stockholders of Comdisco and Redwood, the Securities and Exchange Commission
reviewed the Company's 1993 financial statements and requested that the results
of operations and the loss on disposal of ASI be reclassified as components of
continuing operations since ASI was not deemed a major line of business. As a
result, the Company has classified the respective income and loss from
operations of the disposed division as unusual items within operations in the
accompanying statements of income. The loss of $6.0 million on disposal of the
division is classified in other income (expense) in the accompanying 1993
statement of income. Revenue from this division was approximately $11.2 million
for the year ending December 31, 1993.

         RESTRUCTURING COSTS

         In March 1993, the Company recorded restructuring costs of
approximately $13.5 million associated with a planned restructure of certain
areas of sales, operations and administration due to business conditions. The
restructuring charge included approximately $4.5 million for employee
terminations. The Company terminated approximately 270 employees at an actual
total cost of approximately $4.6 million. In addition, the restructuring charge
included approximately $3.5 million for excess facilities and approximately $2.1
million for the write-off of purchased software and intangibles arising from
required adjustments to the Company's cost structure necessitated by lower
revenue levels. Substantially all of the excess facilities accrual was utilized
by December 31, 1993. The restructuring charge also included an additional
provision for doubtful accounts of approximately $3.0 million, which was
utilized by December 31, 1993 and write-off of certain software development
costs of $.4 million resulting from changes in the systems product strategy.

LEASES

         Equipment and facilities are leased under various capital and operating
leases expiring on different dates through the year 2008. Certain of these
leases contain renewal options. Rental expense was approximately $10.7 million,
$19.0 million and $20.0 million for 1995, 1994 and 1993, respectively.

         In connection with a previous merger, the Company has closed certain
facilities and, accordingly, has accrued for estimated future minimum rent and
maintenance costs related to these facilities. Total costs accrued at December
30, 1995 were $7.9 million of which $2.4 million was included in accrued
liabilities and approximately $5.5 million was included in other long-term
liabilities in the accompanying balance sheet.

         At December 30, 1995, future minimum lease payments under capital and
operating leases and the present value of the capital lease payments were as
follows:

LINE OF CREDIT

         The Company's majority-owned subsidiary, IMS, has a revolving line of
credit with a bank allowing for maximum borrowings of $10.0 million with
interest at the bank's prime rate, interbank offering rates plus 1.25%, or
banker's acceptance plus 1.25%, at the borrower's option. There were no
outstanding borrowings at December 30, 1995 under this agreement. At December
30, 1995, IMS was in full compliance with all covenants and conditions in the
agreement. The line of credit expires April 30, 1997.

COMMITMENTS AND CONTINGENCIES

         As part of its overall investment strategy, the Company has committed
to participating in a venture capital partnership as a limited partner. The
Company's total committed investment of at least $25 million will be made over
the next three to four years.

         The Company is involved in various disputes and litigation matters
which have arisen in the ordinary course of business. These include disputes and
lawsuits related to intellectual property, contract law and employee relations
matters.

                                       38

         The Company filed a complaint in the United States District Court for
the Northern District of California on December 6, 1995 against Avant!
Corporation (formerly known as ArcSys, Inc., "Avant!") and certain of its
employees for misappropriation of trade secrets, copyright infringement,
conspiracy and other illegalities.

         On January 16, 1996, Avant! filed various counterclaims against the
Company and the Company's President and CEO, alleging, inter alia, that the
Company and its President and CEO had cooperated with the Santa Clara County
District Attorney and initiated and pursued its complaint against Avant! for
anti competitive reasons, engaged in wrongful activity in an attempt to
manipulate Avant!'s stock price and utilized certain pricing policies and other
acts to unfairly compete against Avant! in the marketplace. The counterclaim
also alleges that certain unspecified Company insiders engaged in illegal
insider trading with respect to Avant!'s stock. The Company and its President
and CEO believe that each has meritorious defenses to Avant!'s claims, and each
intends to defend such action vigorously.

         Management believes that the ultimate resolution of the disputes and
litigation matters discussed above will not have a material adverse impact on
the Company's financial position or results of operations.

STOCKHOLDERS' EQUITY

         STOCK SPLIT

         In October 1995, the Company's Board of Directors effected a
three-for-two stock split payable in the form of a dividend of one additional
share of the Company's common stock for every two shares owned by stockholders.
Par value remained at $0.01 per share. The stock split resulted in the issuance
of approximately 25.2 million additional shares of common stock from authorized
but unissued shares. Accordingly, all share and per share data have been
adjusted to retroactively reflect the stock split.

         EMPLOYEE STOCK OPTION PLANS

         The Company's Employee Stock Option Plan (the "Plan") provides for the
issuance of either incentive or nonqualified options at an exercise price not
less than fair market value of the stock on the date of grant. Options granted
under the Plan become exercisable over periods of one to four years and expire
five to ten years from the date of grant. During 1993 holders of the Company's
options were given the opportunity to exchange previously granted stock options
for new common stock options exercisable at $5.87 per share, the fair market
value of the common stock on the date of exchange. Under the terms of the new
options, one-third of the shares vest one year from the date of grant and the
remaining shares vest in 24 equal monthly installments. Options to purchase
7,284,039 shares were exchanged.

         During 1993, the Company adopted a Non-Statutory Stock Option Plan (the
"Non-Statutory Plan"). Options granted under the Non-Statutory Plan become
exercisable over a four year period, with one-fourth of the shares vesting one
year from the vesting commencement date and the remaining shares vesting in 36
equal monthly installments. The options granted under the Non-Statutory Plan
generally expire ten years from the date of grant.

         In 1995, the Company's Board of Directors' authorized an additional 4.5
million shares to be issued under the 1993 Non-Statutory Plan. Since directors
and officers of the Company are not eligible to receive options under the
Non-Statutory Plan, stockholder approval is not required nor will it be sought.

         The Company has assumed certain options granted to former employees of
acquired companies ("Acquired Options"). The Acquired Options were assumed by
the Company outside of the Plan, but all are administered as if assumed under
the Plan. All of the Acquired Options have been adjusted to effectuate the
conversion under the terms of the Agreements and Plans of Reorganization between
the Company and the companies acquired. The Acquired Options generally become
exercisable over a four year period and generally expire either five or ten
years from the date of grant. No additional options will be granted under any of
the acquired companies' plans.

1995 Directors Plan is subject to stockholder approval, which will be sought at
the 1996 stockholders' meeting. The Company has reserved 1,117,500 shares of
common stock for issuance under these plans. The Directors Plans provide for the
issuance of nonqualified stock options to nonemployee directors of the Company
with an exercise price equal to the fair market value of the common stock on the
date of grant. Options granted under the Directors Plans have a term of up to
ten years. Certain of the option grants vest one year from the date of grant and

         STOCKHOLDER RIGHTS PLAN

         On February 9, 1996, the Company adopted a new Stockholder Rights Plan
(the "Preferred Rights Plan") to protect stockholders' rights in the event of a
proposed or actual acquisition of 15% or more of the outstanding shares of the
Company's common stock. As part of this plan, each share of the Company's common
stock carries a right to purchase one one-thousandth (1/1000) of a share of
Series A Junior Participating Preferred Stock ("the Right"), par value $.01 per
share of the Company at a price of $240 per one one-thousandth of a share
subject to adjustment. The Rights are subject to redemption at the option of the
Board of Directors at a price of $.01 per Right until the occurrence of certain
events. The Rights expire on February 20, 2006.

         Concurrent with the adoption of the Preferred Rights Plan, the Board of
Directors amended the Company's 1989 Stockholder Rights Plan to provide for the
expiration of the rights thereunder effective February 9, 1996.

         Income (loss) before income taxes for 1995, 1994 and 1993 included
income of approximately $34.2 million, $19.2 million and $9.2 million,
respectively, from the Company's foreign subsidiaries.

         The provision for income taxes is net of the benefit of operating loss
carryforwards totaling $9.7 million, $20.8 million and $2.8 million, for 1995,
1994 and 1993, respectively.

</TABLE>

         The Company has recorded deferred tax assets of $62.6 million offset by
a valuation allowance of $47.8 million. Certain of these deferred tax assets
will affect equity and intangibles and will not be available to offset future
provisions for income taxes and are identified in the above table as "valuation
allowance-equity and intangibles". Realization of the net deferred tax assets of
$14.8 million is dependent on generating sufficient taxable income prior to the
expiration of the loss and tax credit carryforwards. Although realization is not
assured, management believes it is more likely than not that the net deferred
tax assets of $14.8 million will be realized. The amount of the net deferred tax
assets considered realizable, however, could be reduced or increased in the near
term if actual facts, including the estimate of future taxable income, differ
from those estimated.

         The net valuation allowance decreased by $5.5 million in 1995. The
increase in valuation allowance-equity and intangibles of $14.5 million is due
to an increase in the tax benefits related to stock option exercises which are
required to be credited to equity in future periods. This increase in the
valuation allowance-equity and intangibles was offset by a decrease in the
valuation allowance-provision for income taxes of $20.0 million due to the
realization of net operating losses and tax credits generated in prior years.

         The remaining net operating loss carryforwards will expire at various
dates from 1997 through 2008 and tax credit carryforwards will expire at various
dates from 1996 through 2010.

         The Company's federal income tax returns for 1989 through 1991 have
been examined by the Internal Revenue Service ("IRS"). Tax credits of $15.6
million have been disallowed by the IRS. The Company is contesting these
adjustments and is pursuing administrative remedies. Management believes that
adequate provision has been made for any deficiency that may result from this
examination and that the resolution of this matter will not have a material
adverse impact on the Company's financial position or results of operations.

OPERATIONS BY GEOGRAPHIC AREA

         The Company operates primarily in one industry segment; the development
and marketing of computer-aided design software and related services. The
Company's products have been marketed internationally through distributors and
through the Company's subsidiaries in Europe and Asia/Pacific. Intercompany
revenue results from licenses that are based on a percentage of the
subsidiaries' revenue from unaffiliated customers. The following table presents
a summary of operations by geographic area.

                         CADENCE DESIGN SYSTEMS, INC.
                       1995 DIRECTORS STOCK OPTION PLAN
                         ADOPTED ON OCTOBER 3, 1995,
                   AMENDED AND RESTATED ON FEBRUARY 9, 1996
                SUBJECT TO STOCKHOLDER APPROVAL ON MAY 3, 1996

1.       PURPOSE.

         (a) The purpose of the 1995 Directors Stock Option Plan (the "Plan") is
to provide a means by which each director of Cadence Design Systems, Inc., a
Delaware corporation (the "Company"), who is not otherwise at the time of grant
an employee of the Company or of any Affiliate of the Company (each such person
being hereafter referred to as a "Non-Employee Director") will be given an
opportunity to purchase stock of the Company through the grant of options.

         (b) The word "Affiliate" as used in the Plan means any corporation or
other entity which is controlled by the Company, which controls the Company, or
which is under common control with the Company.

         (c) The Company, by means of the Plan, seeks to retain the services of
persons now serving as Non-Employee Directors of the Company, to secure and
retain the services of persons capable of serving in such capacity, and to
provide incentives for such persons to exert maximum efforts for the success of
the Company.

         (d) No option granted under the Plan is intended to be an "incentive
stock option" within the meaning of Section 422 of the Internal Revenue Code of
1986, as amended (the "Code").

2.       ADMINISTRATION.

         (a) The Plan shall be administered by the Board of Directors of the
Company (the "Board") unless and until the Board delegates administration to a
committee, as provided in section 2(c).

         (b) The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan, to construe and interpret
the Plan and options granted under the Plan, and to establish, amend and revoke
rules and regulations for its administration. The Board, in the exercise of this
power, may correct any defect, omission or inconsistency in the Plan or in any
option, in a manner and to the extent it shall deem necessary or desirable to
make the Plan fully effective. All decisions of the Board on such matters shall
be final, binding and conclusive on all persons having an interest in such
decision.

         (c) The Board may delegate administration of the Plan to a committee
composed of not fewer than two (2) members of the Board (the "Committee"). If
administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore possessed
by the Board, subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. The
Board may abolish the Committee at any time and revest in the Board the
administration of the Plan.

3.       SHARES SUBJECT TO THE PLAN.

                                       51
<PAGE>   2
         (a) Subject to the provisions of section 10 relating to adjustments
upon changes in stock, the stock that may be sold pursuant to options granted
under the Plan shall not exceed in the aggregate four hundred fifty thousand
(450,000) shares of the Company's $.01 par value common stock (the "Common
Stock"). If any option granted under the Plan shall for any reason expire or
otherwise terminate without having been exercised in full, the stock not
purchased under such option shall again become available for issuance under the
Plan.

         (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

4.       ELIGIBILITY.

         Options shall be granted only to Non-Employee Directors of the Company.

5.       NON-DISCRETIONARY GRANTS.

         (a) Each person who first becomes a Non-Employee Director after October
3, 1995 shall automatically be granted an option to purchase shares of the
Common Stock on the terms and conditions set forth herein. The number of shares
of the Common Stock which shall be subject to an option granted pursuant to this
section 5(a) shall be equal to 2500 multiplied by the number of calendar
quarters occurring between the date on which such person begins serving as a
director of the Company and the first July 1 occurring after the date such
person becomes a director of the Company. If a person becomes a Non-Employee
Director during a calendar quarter, he or she shall be treated as serving as a
director of the Company for the entire such calendar quarter only if he or she
becomes a Non-Employee Director during the first half of such calendar quarter.

         (b) On July 1 of each year, commencing with July 1, 1996, each person
who on that date is then a Non-Employee Director shall automatically be granted
an option to purchase ten thousand (10,000) shares of Common Stock on the terms
and conditions set forth herein. If the Non-Employee Director is an "Active
Board Member" on that date but is not then serving as the Chairman of the Board,
then such director shall automatically be granted an option to purchase an
additional five thousand (5,000) shares of Common Stock on the terms and
conditions set forth herein. If the Non-Employee Director is serving as the
Chairman of the Board on that date, then such director shall automatically be
granted an option to purchase an additional ten thousand (10,000) shares of
Common Stock on the terms and conditions set forth herein. An "Active Board
Member" shall be defined as a Non-Employee Director who is the chairman of one
committee of the Board and is serving as a member of at least one additional
committee of the Board.

         (c) Each Non-Employee Director who on October 3, 1995 is serving as a
member of the Venture Committee of the Board shall automatically receive on that
date an option to purchase fifteen thousand (15,000) shares of Common Stock on
the terms and conditions set forth herein. The Non-Employee Director who on
October 3, 1995 is serving as the chairman of the Venture Committee of the Board
shall automatically receive on that date an option to purchase an additional
fifteen thousand (15,000) shares of Common Stock on the terms and conditions set
forth herein. In addition, each Non-Employee Director who is selected for the
first time to serve on the Venture Committee after October 3, 1995 automatically
shall, upon the date of his or her initial selection to serve on the Venture
Committee, be granted an option to purchase fifteen thousand (15,000) shares of
Common Stock on the terms and conditions set forth herein. Each Non-Employee
Director who is selected for the first time to serve as the chairman of the
Venture Committee after October 3, 1995 automatically shall, upon the date of
his or her initial selection to serve as the chairman of the Venture Committee,
be granted an option to purchase an additional fifteen thousand (15,000) shares
of Common Stock on the terms and conditions set forth herein.

         (d) On January 30 of each year, commencing with January 30, 1996, each
Non-Employee Director who on that date is then serving as the Chairman of the
Board and has completed five (5) years of service as the Chairman of the Board
shall automatically receive an option to purchase forty five thousand (45,000)
shares of Common Stock on the terms and conditions set forth herein; provided,
however, that no such Non-Employee Director shall receive more than one such
grant under this paragraph 5(d).

                                       52
<PAGE>   3
         (e) If an option would otherwise automatically be granted on or after
October 3, 1995 to a Non-Employee Director under the terms of the Company's 1993
Directors Option Plan (the "1993 Directors Plan"), but cannot be granted in full
because there are insufficient shares of Common Stock remaining in the share
reserve for the 1993 Directors Plan which neither have been issued nor are then
subject to the term of an outstanding option previously granted under the 1993
Directors Plan, then an option shall automatically be granted on the same date
to such Non-Employee Director on the terms and conditions set forth herein. The
number of shares of Common Stock which shall be subject to such an option shall
be that number of shares which would otherwise have been subject to the option
granted under the 1993 Directors Plan on the same date, but as to which such an
option may not be granted under the 1993 Directors Plan to such Non-Employee
Director solely because of the lack of sufficient uncommitted shares in the
share reserve of the 1993 Directors Plan as described above.

6.       OPTION PROVISIONS.

         Each option shall be subject to the following terms and conditions:

         (a) The term of each option commences on the date it is granted and,
unless sooner terminated as set forth herein, expires on the date ten (10) years
from the date of grant (the "Expiration Date"). In any and all circumstances, an
option may be exercised only as to no more than that number of shares as to
which it is exercisable at the time in question under the provisions of section
6(e).

         (b) The exercise price of each option shall be one hundred percent
(100%) of the fair market value of the stock subject to such option on the date
such option is granted. The "fair market value" of the Common Stock shall be the
mean average of the closing price of the Company's common stock for each of the
last twenty trading days prior to the date of the grant of the option on the
national securities exchange, national market system or other trading market on
which the Company's common stock has the highest average trading volume.

         (e) The optionee may elect to make payment of the exercise price under
one of the following alternatives:

                           (i) Payment of the exercise price per share in cash
(by check) at the time of exercise; or

                           (ii) Provided that at the time of the exercise the
Common Stock is publicly traded and quoted regularly in the Wall Street Journal,
payment by delivery of shares of Common Stock already owned by the optionee,
held for the period required to avoid a charge to the Company's reported
earnings, and owned free and clear of any liens, claims, encumbrances or
security interest, which common stock shall be valued at its fair market value
on the last day on which the Common Stock was actively traded preceding the date
of exercise;

                           (iii) Payment by the delivery of the optionee's full
recourse promissory note on such terms as may be determined by the Board which
are not inconsistent with the terms of the Plan; or

                           (iv) Payment by a combination of the methods of
payment specified in subsections 6(c)(i) through 6(c)(iii) above.

         For purposes of section 6(c)(ii), the "fair market value" of Common
Stock shall be the closing price of such stock on the last trading day preceding
the date of delivery of such Common Stock to the Company on the national
securities exchange, national market system or other trading market on which the
Common Stock has the highest average trading volume. If the optionee uses a
promissory note as partial payment of the exercise price pursuant to section
6(c)(iii), then such principal amount of such note may not exceed the maximum
amount permitted by law (including but not limited to the limitation under the
Delaware General Corporation Law that the par value of shares of stock may not
be paid with a promissory note) and interest shall be compounded at least
annually and shall be charged at no less than the minimum rate of interest
necessary to avoid the treatment as interest, under any applicable provisions of
the Code, of any amounts other than amounts stated to be interest under the
terms of such promissory note.

                                       53
<PAGE>   4
         Notwithstanding the foregoing, this option may be exercised pursuant to
a program developed under Regulation T as promulgated by the Federal Reserve
Board which results in the receipt of cash (or check) by the Company either
prior to the issuance of shares of the Company's common stock or pursuant to the
terms of irrevocable instructions issued by the optionee prior to the issuance
of shares of the Company's common stock.

         (d) An option shall not be transferable except by will or by the laws
of descent and distribution or pursuant to a qualified domestic relations order
satisfying the requirements of Rule 16b-3 and the rules thereunder ("QDRO"), and
shall be exercisable during the lifetime of the person to whom the option is
granted only by such person, by his guardian or legal representative, or by any
transferee pursuant to a QDRO. The person to whom the Option is granted may, by
delivering written notice to the Company, in a form satisfactory to the Company,
designate a third party who, in the event of the death of the optionee, shall
thereafter be entitled to exercise the option.

         (e)      (i) An option granted pursuant to section 5(a) or 5(b) shall
vest and become exercisable in full on the first June 30 following the grant of
such option; provided, however, the optionee has continuously served in the same
capacity which entitled him or her to the grant of such option from the date of
grant until and including the next following June 30.

                  (ii) An option granted pursuant to section 5(c), 5(d) or 5(e)
shall become exercisable in installments over a period of three years from the
date of grant at the rate of one-third (1/3rd) of the total number of shares
subject to such option upon the first anniversary of the date of grant and
subsequently at the rate of one thirty-sixth (1/36th) of the total number of
shares subject to the option a month, in twenty-four (24) equal monthly
installments; provided, however, that the optionee has, during the entire period
from the grant date to such vesting date, continuously served in the same
capacity which entitled him or her to the grant of such option, whereupon such
option shall become fully exercisable in accordance with its terms with respect
to that portion of the shares represented by that installment.

         (f) The Company may require any optionee, or any person to whom an
option is transferred under section 6(d), as a condition of exercising any such
option: (i) to give written assurances satisfactory to the Company as to the
optionee's knowledge and experience in financial and business matters; and (ii)
to give written assurances satisfactory to the Company stating that such person
is acquiring the stock subject to the option for such person's own account and
not with any present intention of selling or otherwise distributing the stock.
These requirements, and any assurances given pursuant to such requirements,
shall be inoperative if (i) the issuance of the shares upon the exercise of the
option has been registered under a then-currently effective registration
statement under the Securities Act of 1933, as amended (the "Securities Act"),
or (ii), as to any particular requirement, a determination is made by counsel
for the Company that such requirement need not be met in the circumstances under
the then applicable securities laws. The Company may require any optionee to
provide such other representations, written assurances or information which the
Company shall determine is necessary, desirable or appropriate to comply with
applicable securities laws as a condition of granting an option to the optionee
or permitting the optionee to exercise the option. The Company may, upon advice
of counsel to the Company, place legends on stock certificates issued under the
Plan as such counsel deems necessary or appropriate in order to comply with
applicable securities laws, including, but not limited to, legends restricting
the transfer of the stock.

         (g) Notwithstanding anything to the contrary contained herein, an
option may not be exercised unless the shares issuable upon exercise of such
option are then registered under the Securities Act or, if such shares are not
then so registered, the Company has determined that such exercise and issuance
would be exempt from the registration requirements of the Securities Act.

7.       COVENANTS OF THE COMPANY.

         (a) During the terms of the options granted under the Plan, the Company
shall keep available at all times the number of shares of the Common Stock
required to satisfy such options.

                                       54
<PAGE>   5
         (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of Common Stock upon exercise of the options granted under
the Plan; provided, however, that this undertaking shall not require the Company
to register under the Securities Act either the Plan, any option granted under
the Plan, or any stock issued or issuable pursuant to any such option. If, after
reasonable efforts, the Company is unable to obtain from any such regulatory
commission or agency the authority which counsel for the Company deems necessary
for the lawful issuance and sale of stock under the Plan, the Company shall be
relieved from any liability for failure to issue and sell stock upon exercise of
such options.

8.       USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of Common Stock pursuant to options granted
under the Plan shall constitute general funds of the Company.

9.       MISCELLANEOUS.

         (a) Neither an optionee nor any person to whom an option is transferred
under section 6(d) shall be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares subject to such option unless and
until such person has satisfied all requirements for exercise of the option
pursuant to its terms.

         (b) Throughout the term of any option granted pursuant to the Plan, the
Company shall make available to the holder of such option, not later than one
hundred twenty (120) days after the close of each of the Company's fiscal years
during the option term, upon request, such financial and other information
regarding the Company as comprises the annual report to the stockholders of the
Company provided for in the Bylaws of the Company and such other information
regarding the Company as the holder of such option may request under applicable
law.

         (c) Nothing in the Plan or in any instrument executed pursuant thereto
shall confer upon any Non-Employee Director any right to continue in the service
of the Company or any Affiliate in any capacity or shall affect any right of the
Company, its Board or stockholders or any Affiliate to remove any Non-Employee
Director pursuant to the Company's Bylaws and the provisions of the Delaware
General Corporation Law (or the laws of the Company's state of incorporation
should that change in the future).

         (d) No Non-Employee Director, individually or as a member of a group,
and no beneficiary or other person claiming under or through him, shall have any
right, title or interest in or to any option reserved for the purposes of the
Plan except as to such shares of common stock, if any, as shall have been
reserved for him pursuant to an option granted to him.

         (e) In connection with each option made pursuant to the Plan, it shall
be a condition precedent to the Company's obligation to issue or transfer shares
to a Non-Employee Director, or to evidence the removal of any restrictions on
transfer, that such Non-Employee Director make arrangements satisfactory to the
Company to insure that the amount of any federal or other withholding tax
required to be withheld with respect to such sale or transfer, or such removal
or lapse, is made available to the Company for timely payment of such tax.

         (f) The size of the Plan's share reserve set forth in section 3, the
size of individual option grants described in section 5, and all other
references in the Plan to specific numbers of shares of the Common Stock reflect
and have taken into account the Company's three-for-two (3:2) stock dividend
effective as of October 31, 1995, including all options granted under the Plan
prior to October 31, 1995.

10.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a) If any change is made in the Common Stock subject to the Plan, or
subject to any option granted under the Plan (through merger, consolidation,
reorganization, recapitalization, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the

                                       55
<PAGE>   6
Company), the Plan and outstanding options will be appropriately adjusted in the
class(es) and maximum number of shares subject to the Plan and the class(es) and
number of shares and exercise price per share of stock subject to outstanding
options. Such adjustments shall be made by the Board, the determination of which
shall be final, binding, and conclusive. (The conversion of any convertible
securities of the Company shall not be treated as a "transaction not involving
the receipt of consideration by the Company.") No adjustment shall result in the
creation of a fractional share of stock or in an exercise price per share of
stock expressed in units of less than one cent ($.01).

         (b) In the event of: (1) a dissolution, liquidation, or sale of all or
substantially all of the assets of the Company; (2) a merger or consolidation in
which the Company is not the surviving corporation; (3) a reverse merger in
which the Company is the surviving corporation but the shares of the Company's
common stock outstanding immediately preceding the merger are converted by
virtue of the merger into other property, whether in the form of securities,
cash or otherwise; or (4) the acquisition by any person, entity or groups within
the meaning of Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), or any comparable successor provisions (excluding
any employee benefit plan, or related trust, approved or maintained by the
Company or any Affiliate of the Company) of the beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable
successor rule) of securities of the Company representing at least fifty percent
(50%) of the combined voting power entitled to vote in the election of
directors, then to the extent not prohibited by applicable law, the time during
which options outstanding under the Plan may be exercised shall be accelerated
prior to such event and the options terminated if not exercised after such
acceleration and at or prior to such event.

11.      AMENDMENT OF THE PLAN.

         (a) The Board at any time, and from time to time, may amend the Plan
and/or some or all outstanding options granted under the Plan, provided,
however, that the Board shall not amend the Plan more than once every six (6)
months, with respect to the provisions of the Plan which relate to the amount,
price and timing of grants, other than to comport with changes in the Code, the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or the
rules thereunder. Except as provided in section 10 relating to adjustments upon
changes in stock, no amendment shall be effective unless approved by the
stockholders of the Company within twelve (12) months before or after the
adoption of the amendment, where the amendment would:

                           (i) Increase the number of shares which may be issued
under the Plan;

                           (ii) Modify the requirements as to eligibility for
participation in the Plan (to the extent such modification requires stockholder
approval in order for the Plan to comply with the requirements of Rule 16b-3);
or



                           (iii) Modify the Plan in any other way if such
modification requires stockholder approval in order for the Plan to comply with
the requirements of Rule 16b-3.

         (b) Rights and obligations under any option granted before any
amendment of the Plan shall not be impaired by such amendment unless (i) the

                          CADENCE DESIGN SYSTEMS, INC.
                          SENIOR EXECUTIVE BONUS PLAN
                      JANUARY 1, 1996 - DECEMBER 31, 1996


The purpose of the Senior Executive Bonus Plan is to motivate and reward the
Senior Executives of the company to profitably grow Cadence and achieve
corporate goals. The plan provides for a cash payment after January 1, 1997. The
financial performance will be based on the audited financial statements.

The Target Bonus Pool will be made up of the sum of each participant's salary
times a percentage as assigned by the Compensation Committee. The Actual Bonus
Pool will be a percentage of the Target Bonus Pool determined based on Cadence's
performance against Earnings Per Share (EPS) targets.

If Earnings Per Share fall outside the target range, the Bonus Pool will be
determined at the sole discretion of the Board of Directors.

The target bonus for each Senior Executive will be pre-established by the
Compensation Committee of the Board of Directors.

The individual Senior Executive bonus target will be adjusted in proportion to
the adjustment of the Bonus Pool, the portion of 1996 actively employed by
Cadence as a Senior Executive and an individual performance factor with a range
of .5 to 1.5 as assigned or approved by the Compensation Committee of the Board
of Directors. There will be no adjustment for the other Senior Executives if a
Senior Executive leaves the Company. The total of the individual bonuses will be
controlled to the bonus pool, as adjusted by the Earnings Per Share performance
factor.

The Board of directors reserves the right to terminate or modify this plan at
any time. The plan is only effective for 1996, and any future Senior Executive
Bonus or other bonus plan is at the discretion of the Board of Directors.

In order for the Bonus to be paid to a Senior Executive, he/she must be in the
active employment of Cadence on the date checks are distributed. All forfeitures
revert to Cadence.

                          CADENCE DESIGN SYSTEMS, INC.
                       CHIEF EXECUTIVE OFFICER BONUS PLAN
                        EFFECTIVE AS OF JANUARY 1, 1996


The purpose of the Chief Executive Officer Bonus Plan (the "Plan") is to
motivate and reward that individual who is serving as the Company's Chief
Executive Officer ("CEO") to improve the Company's profitability and achieve the
established corporate goals of the Company. The Plan provides for a cash payment
after the end of the Company's fiscal year ending December 31, 1996 and after
the end of each subsequent fiscal year. The Company's financial performance for
a given fiscal year will be based on the audited financial statements prepared
by the Company's outside accounting firm. Amounts paid under the Plan are
intended to be "performance-based compensation" within the meaning of section
162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), and the
Plan shall be interpreted in accordance with that intent.

The target bonus amount for the CEO will be established by the Compensation
Committee of the Board of Directors for a given fiscal year within the first
ninety (90) days of that fiscal year. The target bonus amount shall be expressed
as a percentage of the CEO's base salary for that fiscal year, which base salary
shall also be established by the Compensation Committee of the Board of
Directors within the first ninety (90) days of that fiscal year.

The CEO's actual bonus for a given fiscal year shall be determined by the
Company's achievement of the Earnings Per Share ("EPS") target established by
the Compensation Committee of the Board of Directors for a given fiscal year
within the first ninety (90) days of that fiscal year. For purposes of the Plan,
"Earnings Per Share" shall be determined by applying generally accepted
accounting principles ("GAAP") and excluding the impact of any significant
unusual or non-recurring items. If the Earnings Per Share target is equalled by
the Company's performance, then the CEO's actual bonus shall be equal to the
target bonus amount for such year. If the Company's performance exceeds the
Earnings Per Share target, then the CEO's actual bonus shall be greater than the
target bonus amount for such year. If the Company's performance fails to reach
the Earnings Per Share target, then the CEO's actual bonus shall be less than
the target bonus amount for such year, and in some cases it is possible that no
bonus may be paid. The schedule setting forth the relationship between the
Company's financial performance for a given fiscal year expressed in terms of
Earnings Per Share and the CEO's actual bonus shall be established by the
Compensation Committee of the Board of Directors for a given fiscal year within
the first ninety (90) days of that fiscal year.

In the event that the Company's actual Earnings Per Share for a fiscal year
falls between two of the numbers for Earnings Per Share selected by the
Compensation Committee of the Board of Directors on the schedule ("EPS
Numbers"), then the percentage of the CEO's target bonus amount which will be
paid as the CEO's actual bonus (the "amount percentage") shall be determined by
the sum of the following two percentages: (1) the "amount percentage" matched
with the lower of the two EPS Numbers on the schedule plus (2) the product
(rounded to the next higher full percentage point) of the number of percentage
points between the "amount percentages" for the two EPS Numbers, multiplied by a
fraction, the numerator of which is the difference between the Company's actual
Earnings Per Share and the lower EPS Number and the denominator of which is the
number of cents between the two EPS Numbers.

In no event may the CEO's actual bonus for a given fiscal year exceed
$2,000,000.

The CEO's actual bonus for a given fiscal year shall be reduced by the amount
which the CEO receives with respect to the same fiscal year under the terms of
the Company's Senior Executive Bonus Plan for that fiscal year.

The amount of the CEO's actual bonus for a given fiscal year shall be certified
in writing by the Compensation Committee of the Board of Directors prior to
payment.

                                       59
<PAGE>   2
Any individual who serves as the Company's Chief Executive Officer for a given
fiscal year shall automatically be eligible to participate in the Plan. If an
individual becomes Chief Executive Office during a fiscal year, that
individual's target bonus amount, base salary, EPS target, and schedule of
adjustments to the target bonus amount based upon actual EPS results, shall be
established by the Compensation Committee before the first 25% of the remainder
of that fiscal year has elapsed. These determinations of the Compensation
Committee shall be applied to the period of time remaining in the fiscal year
after the individual became Chief Executive Officer, or such shorter period of
time within the fiscal year determined by the Compensation Committee. In order
to receive a bonus payment under the Plan for a given fiscal year, the
individual must be employed by the Company on the date that bonus checks are
distributed for that fiscal year, or have terminated employment prior to that
time on account of death or disability.

The Compensation Committee of the Board of Directors may terminate the Plan at
any time, for any or no reason, and may also amend the Plan in order to reduce
the amount of the CEO's bonus payment at any time, for any or no reason. The
Compensation Committee of the Board of Directors shall be responsible for all
matters of interpretation of the terms of the Plan, including the authority to
make decisions regarding matters not expressly addressed in the Plan, and the
decision of the Compensation Committee shall be final and binding on all persons
having an interest in the Plan.

                              DEFERRED COMPENSATION

         3.1 DEFERRED COMPENSATION. (a) Each participating Employee may elect,
in accordance with Section 3.3 of this Plan, to defer annually the receipt of a
portion of the Compensation for active service otherwise payable to him or her
by Employer during each Plan Year or portion of a Plan Year that the Employee
shall be employed by the Employer. Any Compensation deferred by Employee
pursuant to Section 3.3 shall be recorded by the Employer in an Account,
maintained in the name of the Employee, which Account shall be credited with a
dollar amount equal to the total amount of Compensation deferred during each
Plan Year under the Plan, together with earnings thereon credited in accordance
with Section 3.7 and expenses allocated thereto in accordance with Section 3.8.
The amount or percentage of Compensation that Employee elects to defer under
Section 3.3 will remain constant for the year of the election and shall not be
subject to change during such year. Each such deferral election as to "base
salary" or discontinuance of a deferral election as to "base salary" will
continue in force for each successive year until or unless suspended or modified
by the filing of a subsequent election with the Employer by the Employee in
accordance with Section 3.3 of the Plan. Each deferral election as to an
Employee's "cash bonus" shall continue in force only for the single year with
respect to which it was made and shall not apply to any successive years. Any
deferral election with respect to a "cash bonus" must be made prior to the time
the amount of the bonus is determined, prior to the end of the period of time as
to which the bonus is awarded, and at a time that the amount of any such bonus
remains substantially uncertain. All deferrals pursuant to this Section 3.1
shall be fully vested at all times. Deferral elections shall be subject to a
minimum dollar and maximum percentage amounts as follows: (i) the minimum annual
deferral amount is $10,000, which shall be withheld from the participating
Employee's "base salary" and "cash bonus," and (ii) the maximum deferral
percentage amount is 80% of the Employee's "base salary" and 100% of the
Employee's "cash bonus". For purposes of the Plan, "base salary" for a given
Plan Year means an "Employee's regular annual compensation payable during the
Plan Year, excluding bonuses, commissions, overtime, incentive payments,
non-monetary awards, compensation deferred pursuant to all Section 125
(cafeteria) or Section 401(k) (savings) plans of the Employer and other special
compensation, and reduced by the tax withholding obligations imposed on the
Employer and any other withholding requirements imposed by law with respect to
such amounts. For purposes of the Plan, "cash bonus" shall mean amounts (if any)
awarded under the bonus policies maintained by the Employer and any commissions
earned on sales.

                  (a) Employer shall not be obligated to make any other
contribution to the Plan on behalf of any Employee at any time. Employer may
make Employer Contributions to the Plan on behalf of one or more Employees.
Employer Contributions, if any, made to Accounts of Employees shall be
determined in the sole and absolute discretion of the Employer, and may be made
without regard to whether the Employee to whose account such contribution is
credited has made, or is making, contributions pursuant to Section 3.1(a). The
Employer shall not be bound or obligated to apply any specific formula or basis
for calculating

                                       63
<PAGE>   4
the amount of any Employer Contributions and Employer shall have sole and
absolute discretion as to the allocation of Employer Contributions among
participating Employee Accounts. The use of any particular formula or basis for
making an Employer Contribution in one Plan Year shall not bind or obligate the
Employer to use such formula or basis in any other Plan Year. Employer
Contributions may be subject to a substantial risk of forfeiture in accordance
with the terms of a vesting schedule, which may be selected by the Employer in
its sole and absolute discretion.

                  (b) Amounts deferred under the Plan shall be calculated and
withheld from the Employee's base salary and/or cash bonus after such
compensation has been reduced to reflect any tax withholding obligations imposed
on the Employer, any other withholding requirements imposed by law, salary
reduction contributions to the Employer's Code Section 125 (cafeteria) and Code
Section 401(k) (savings) plans, but before any reductions for contributions to
the Employer's Code Section 423 (employee stock purchase) plan or the Cadence
Design Systems, Inc. 1994 Deferred Compensation Plan.

         3.2 PAYMENT OF ACCOUNT BALANCES. (a) The Employee shall elect whether
he or she will receive distribution of his or her entire Account, subject to tax
withholding requirements, (i) upon reaching a specified age, (ii) upon passage
of a specified number of years, (iii) upon termination of employment of Employee
with Employer, (iv) upon the earlier to occur of (A) termination of employment
of Employee with Employer or (B) passage of a specified number of years or
attainment of a specified age, or (v) upon the later to occur of (A) termination
of employment of Employee with Employer or (B) passage of a specified number of
years or attainment of a specified age, as elected by Employee in accordance
with the form established by the Committee. Such form may permit an election
among some or all of the alternatives listed in this Section 3.2, as determined
in the Committee's sole discretion. A designation of the time of distribution
shall be required as a condition of participation under this Plan. The Employee
shall also elect to receive all amounts payable to him or her in a lump sum or
in equal monthly installments over a designated period of five or ten years,
pursuant to the provisions of Section 3.2(e). These elections shall be made in
accordance with Section 3.4 of this Plan.

                  (a) Distribution shall be made to the maximum extent allowable
under the election made by Employee, except that no distribution shall be made
to the extent that the receipt of such distribution, when combined with the
receipt of all other "applicable employee remuneration" (as defined in Code
Section 162(m)(4)), would cause any remuneration received by the Employee to be
nondeductible by the Employer under Code Section 162(m)(1). The portion of any
distributable amount that is not distributed by operation of this Section 3.2(b)
shall be distributed in subsequent years in the manner elected by the Employee
until the Employee's Account has been fully liquidated. For Employees who have
elected to receive payment in a lump sum or over five or ten years, the
commencement date of the lump sum payment or the five or ten-year period
(whichever is applicable) shall be automatically extended, when necessary to
satisfy the requirements of this subsection, for one-year periods until all
Account balances have been distributed in the manner elected by the Employee.

                  (b) Upon termination of Employee's employment with Employer by
reason of death or Permanent Disability prior to the time when payment of
Account balances otherwise would commence under the provisions of Section
3.2(a), Employee or Employee's designated Beneficiary will be entitled to
receive all amounts credited to the Account of Employee as of the date of his or
her death or Permanent Disability (notwithstanding any contrary election to
receive distributions under the first sentence of Section 3.2(a)). Upon
termination of Employee's employment with Employer by reason other than death or
Permanent Disability prior to the date when payment of Account balances
otherwise would commence under the provisions of Section 3.2(a), the Employer
may, in the sole discretion of the Committee, distribute to Employee or
Employee's designated Beneficiary all amounts credited to the Employee's Account
as of the date of such termination (notwithstanding any contrary election to
receive distributions under the first sentence of Section 3.2(a)). Said amounts
shall be payable in the form determined pursuant to the provisions of Section
3.2(e).

                  (c) Upon the death of Employee prior to complete distribution
to him or her of the entire balance of his or her Account (and after the date of
termination of employment with Employer), the balance of his or her Account on
the date of death shall be payable to Employee's designated Beneficiary pursuant
to Section 3.2(e). Notwithstanding any other provision of the Plan to the
contrary, except for Section 3.2(f), the Employee's designated Beneficiary may
receive the distribution of the remaining portion of such

                                       64
<PAGE>   5
deceased Employee's Account in the form of a lump sum if the Beneficiary
requests such a distribution and the Committee, in its sole discretion, consents
to such a distribution.

                  (d) The Employer shall distribute or direct distribution of
the balance of amounts previously credited to Employee's Account, in a lump sum,
or in monthly installments over a period of five (5) years or ten (10) years, as
Employee shall designate. A designation of the form of distribution shall be
required as a condition of participation under this Plan. Distribution of the
lump sum or the first installment generally shall be made or commence within
ninety (90) days following the date specified in the first sentence of Section
3.2(a). Subsequent installments, if any, shall be made on the first day of each
month following the first installment as determined by Employer. The amount of
each installment shall be calculated by dividing the Account balance as of the
date of the distribution by the number of installments remaining pursuant to the
Employee's distribution election. Each such installment, if any, shall take into
account earnings credited to the balance of the Account remaining unpaid. The
Employee's distribution election shall be in the form established by the
Committee in accordance with the terms of the Plan.

                  (e) Notwithstanding any other provisions of the Plan or the
Trust to the contrary, no distribution will be made pursuant to the terms of the
Plan if the distribution would require either the transfer of a limited
partnership interest in Telos Venture Partners, L.P. or any other venture
capital investment partnership in which some or all of the assets of the Trust
might be invested (the "Partnership") or a distribution of assets from the
Partnership. In addition, no distribution will be made if the Committee
determines in its sole discretion that the Plan's assets would be insufficient
to satisfy any future capital calls anticipated to be made by the General
Partner of the Partnership, or if the Employee's Account has any amounts
relating to unpaid debt or expenses thereon allocated to such Account. The terms
of an Employee's election shall be followed to the fullest extent possible upon
the distribution of assets from the Partnership to the Trust as determined in
accordance with the terms of the Partnership Agreement. No provision of this
Plan or the Trust Agreement (except for those provisions relating to the
Insolvency of the Employer as set forth in Article 7 of the Trust Agreement)
shall have any impact on the operation of the Partnership.

         3.3 ELECTION TO DEFER COMPENSATION. Each election of an Employee to
defer Compensation as provided in Section 3.1 of the Plan shall be in writing,
signed by the Employee, and delivered to Employer, together with all other
documents required under the provisions of this Plan, at least twenty (20) days
(or such other period of time determined by the Committee and communicated to
those Employees who are eligible to participate in the Plan) prior to the
beginning of the Plan Year with respect to which the Compensation to be deferred
is otherwise payable to Employee; provided, however, that an Employee who is
hired or promoted during a Plan Year to a position of eligibility for
participation in the Plan shall have thirty (30) days from the date of
notification of eligibility for participation in the Plan in which to submit the
required election documents for the then current Plan Year. Any deferral
election made by Employee shall be irrevocable with respect to any Compensation
covered by such election, including Compensation payable in the Plan Year in
which an election suspending or modifying the prior deferral election for the
subsequent Plan Year is delivered to the Employer. The Employer shall withhold
the amount or percentage of base salary specified to be deferred in equal
amounts for each payroll period and shall withhold the amount or percentage of
cash bonus specified to be deferred at the time or times such bonus is or
otherwise would be paid to the Employee. The election to defer Compensation
shall be in the form established by the Committee in accordance with the terms
of the Plan.

         3.4 DISTRIBUTION ELECTION. The initial distribution election of an
Employee as provided in Section 3.2 of this Plan shall be in writing, signed by
the Employee, and delivered to Employer, together with all other documents
required under the provisions of this Plan, at least twenty (20) days (or such
other period of time determined by the Committee and communicated to those
Employees who are eligible to participate in the Plan) prior to the beginning of
the Plan Year with respect to which the distribution election is to apply;
provided, however, that an Employee who is hired or promoted during a Plan Year
to a position of eligibility for participation in the Plan shall have thirty
(30) days from the date of notification of eligibility for participation in the
Plan in which to submit the required election documents for the then current
Plan Year. If permitted by the Committee, an Employee may change the terms of
his or her initial distribution election by making a new election, and any such
new election will be effective as of the later of the date that is (a) six (6)
months following the date the new election is made or (b) the first day of the
Plan Year following the Plan Year in which the new election is made and will
apply to the Employee's entire Account.

                                       65
<PAGE>   6
An Employee may not make a new election once distributions from the Plan have
commenced or which would first become effective at a time when distributions
from the Plan have commenced. Employee's distribution election shall be in the
form established by the Committee in accordance with the terms of the Plan.

         3.5 PAYMENT UPON CHANGE IN CONTROL. Notwithstanding any other provision
of this Plan, except Section 3.2(f), the aggregate balances credited to and held
in the Employees' Accounts shall be distributed to Employees in a lump sum
within thirty (30) days following a Change in Control, as defined in Section
5.1.

         3.6 EMPLOYEE'S RIGHTS UNSECURED. The right of the Employee or his or
her designated Beneficiary to receive a distribution hereunder shall be an
unsecured claim against the general assets of the Employer, and neither the
Employee nor his or her designated Beneficiary shall have any rights in or
against any amount credited to his or her Account or any specific assets of the
Employer, except as otherwise provided in the Trust. Nothing contained in this
Plan, and no action taken pursuant to its provisions, shall create or be
construed to create a trust of any kind or a fiduciary relationship between the
Plan and the Employer or any other person.

         3.7 INVESTMENT OF CONTRIBUTIONS. (a) The investment options available
to each Employee shall be determined by the Employer and described in a separate
written document, a copy of which shall be attached hereto and by this reference
is incorporated herein. Initially the Employer intends to invest all of the
assets of the Trust to acquire a limited partnership interest in the
Partnership, and investment in the Partnership shall be the sole investment
option available to Employees. In the event that the Employer makes more than
one investment option available to Employees, each Employee shall have the sole
and exclusive right to direct the Trustee as to the investment of his or her
Accounts among those investment options in accordance with policies and
procedures implemented by the Trustee and the terms and conditions of those
investment options. Employer shall not be liable for any investment decision
made by any Employee while such funds are held by the Trustee. Employer may
provide in its sole discretion for the transfer of some or all of the Plan's
assets from the Trust to another trust established under the terms of a
non-qualified deferred compensation plan sponsored by the Employer in order to
provide additional investment options to Employees; provided, however, that
prior to any such transfer, Employer shall have determined (after consulting
with legal counsel for Employer with respect to the Plan) that such transfer
shall not cause any participating Employee to incur any income tax liability
with respect to his or her benefits under the Plan and shall not impair the
rights of any Employee to accrue and/or receive benefits under the Plan.

                  (a) Accounts shall be credited with the actual financial
performance or earnings generated by such investments made by the Trustee in
accordance with the terms of the Plan and Trust, until the Account has been
fully distributed to the Employee or to the Employee's designated Beneficiary.
Notwithstanding the foregoing, Accounts shall be maintained, credited and
debited with respect to an investment in the Partnership as provided under the
terms of the Partnership Agreement. Furthermore, the Trust's limited partnership
interest in the Partnership for a given Plan Year which is acquired with
deferrals of Compensation from participating Employees shall be allocated to the
Accounts of those participating Employees in the same proportion as the deferred
amounts invested in the Partnership for such Plan Year are allocated to those
Accounts. The Trust's limited partnership interest in the Partnership for a
given Plan Year which is acquired with loan proceeds shall be allocated to the
Accounts of those participating Employees who remain employed by the Employer
(or a subsidiary or affiliate of the Employer) at the end of such Plan Year in
the same proportion as the deferred amounts invested in the Partnership for such
Plan Year are allocated to the Accounts of those remaining Employees.

                  (b) Notwithstanding any provision in this Section 3.7 to the
contrary, the Committee may determine not to take account of Employee's
designated investments, if any, and determine to have the Employee's Account
invested in any other manner as the Committee shall determine. The Committee may
also designate how the Plan's assets shall be invested for interim short-term
periods of time pending investment in the Partnership or following distribution
from the Partnership but prior to distribution from the Plan or re-investment in
the Plan (or a similar non-qualified deferred compensation plan) in another
investment option.

         3.8 ALLOCATION OF EXPENSES

                  (a) Expenses of administering the Plan and the Trust which are
paid out of the Trust Fund shall be allocated to the Accounts of participating
Employees on a periodic basis determined by the Committee using any method which
the Committee determines is fair and equitable to participating Employees. The
selection of a given method of allocating expenses among participating
Employees' Accounts shall not be deemed to restrict the Committee in any manner
whatsoever from selecting a different method for future allocations or to imply
that a different method would not be fair and equitable to participating
Employees.

                  (b) From time to time the Trustee may borrow funds to satisfy
the obligations of the Trust, whether to meet capital calls issued by the
General Partner of the Partnership or otherwise. The principal amount of any
such loan shall be allocated to the Accounts of participating Employees in a
manner which the Committee determines is fair and equitable, and for loan
principal used to acquire an interest in the Partnership, is also consistent
with the allocation of interests in the Partnership acquired with loan proceeds
as described in Section 3.7. The costs associated with interest expenses on that
principal amount (and any interest expenses incurred with respect to previously
accrued but unpaid interest), any other expenses incurred with respect to that
principal amount, as well as the costs associated with repayment of principal,
shall be allocated to the same Accounts to which the principal amounts were
allocated initially in proportion to the principal amounts allocated to the
Accounts at such time. Once additional interest or other expenses are allocated
to an Account, such expenses shall be treated as principal with respect to
future allocations of expenses related to that debt. Notwithstanding the
foregoing, the Committee shall have the authority to establish a different
method for allocating costs, expenses, and/or repayment of principal which it
concludes is fair and equitable to participating Employees. The selection of a
given method of allocating expenses among participating Employees' Accounts
shall not be deemed to restrict the Committee in any manner whatsoever from
selecting a different method for future allocations or to imply that a different
method would not be fair and equitable to participating Employees.

                           DESIGNATION OF BENEFICIARY

         4.1 DESIGNATION OF BENEFICIARY. Employee may designate a Beneficiary or
Beneficiaries to receive any amount due hereunder by Employee by written notice
thereof to Employer at any time prior to his or her death and may revoke or
change the Beneficiary designated therein without the Beneficiary's consent by
written notice delivered to Employer at any time and from time to time prior to
Employee's death. If Employee is married and a resident of a community property
state, one half of any amount due hereunder which is the result of an amount
contributed to the Plan during such marriage while residing in a community
property state is the community property of the Employee's spouse and Employee
may designate a Beneficiary or Beneficiaries to receive only the Employee's
one-half interest. If Employee shall have failed to designate a Beneficiary, or
if no such Beneficiary shall survive him or her, then such amount shall be paid
to his or her estate. Designations of Beneficiaries shall be in the form
determined by the Committee.

                                CHANGE IN CONTROL

         5.1 CHANGE IN CONTROL. For purposes of this Plan, a "Change of Control"
means the happening of any of the following:

                  (i) When any "person," as such term is used in Sections 13(d)
and 14(d) of the Securities Exchange Act of 1934 as amended ("Exchange Act")
(other than the Employer, a subsidiary of the Employer or an employee benefit
plan sponsored by the Employer or a subsidiary of the Employer, including any
trustee of such plan acting as trustee) is or becomes the "beneficial owner" (as
defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of
securities of the Employer representing fifty percent (50%) or more of the
combined voting power of the Employer's then outstanding securities, where such
person's beneficial ownership of the Employer's securities was not initiated by
the Employer or approved by the Employer's Board of Directors; or

                  (ii) The occurrence of a transaction requiring shareholder
approval, and involving the sale of all or substantially all of the assets of
the Employer or the merger of the Employer with or into another corporation,
where such merger was not initiated by the Employer or approved by the
Employer's Board of Directors; or

                  (iii) A change in the composition of the Board of Directors of
the Employer, as a result of which fewer than a majority of the directors are
Incumbent Directors. "Incumbent Directors" shall mean directors who either (A)
are directors of the Employer as of the date hereof, or (B) are elected, or
nominated for election, to the Board of Directors of the Employer with the
affirmative votes of at least a majority of the Incumbent Directors at the time
of such election or nomination (but shall not include an individual whose
election or nomination is in connection with an actual or threatened proxy
contest relating to the election of directors to the Employer or an actual or
threatened tender offer with respect to the Employer's publicly traded
securities); or

                  (iv) Any liquidation or dissolution of the Employer.

                                        6

                                TRUST PROVISIONS

         6.1 TRUST AGREEMENT. The Employer shall establish the Trust within an
administratively reasonable period of time following the adoption of the Plan
for the purpose of retaining assets set aside by Employer pursuant to the Trust
Agreement for payment of amounts payable pursuant to the Plan. Any benefits not
paid from the Trust shall be paid solely from Employer's general funds, and any
benefits paid from the Trust shall be credited against and reduce by a
corresponding amount the Employer's liability to Employees under the Plan. No
special or separate fund, other than the Trust Agreement, shall be required to
be established and no other segregation of assets shall be required to be made
to assure the payment of any benefits hereunder. All Trust Funds shall be
subject to the claims of general creditors of the Employer in the event the
Employer is Insolvent as defined in Article 7 of the Trust Agreement. The
obligations of the Employer to pay benefits under the Plan constitute an
unfunded, unsecured promise to pay and Employee shall have no greater rights
than general creditors of the Employer.

                                        7

                            AMENDMENT AND TERMINATION

         7.1 AMENDMENT. The Committee shall have the right to amend this Plan at
any time and from time to time, including a retroactive amendment. Any such
amendment shall become effective upon the date stated therein, and shall be
binding on all Employees, except as otherwise provided in such amendment;

                                       68
<PAGE>   9
provided, however, that any such amendment shall not affect adversely benefits
payable to an affected Employee without the Employee's written approval.

         7.2 TERMINATION. The Committee shall have the right to terminate this
Plan at any time and direct the lump sum payments of all assets held by the
Trust if the Employer is not Insolvent at that time (as defined in Article 7 of
the Trust Agreement), notwithstanding any other provision of the Plan to the
contrary (except for Section 3.2(f)).

                                        8

                                 ADMINISTRATION

         8.1 ADMINISTRATION. The Committee shall administer and interpret this
Plan in accordance with the provisions of the Plan and the Trust Agreement. Any
determination or decision by the Committee shall be conclusive and binding on
all persons who at any time have or claim to have any interest whatever under
this Plan.

         8.2 LIABILITY OF COMMITTEE; INDEMNIFICATION. To the maximum extent not
prohibited by law, no member of the Committee shall be liable to any person and
in any event shall be indemnified by the Employer for any action taken or
omitted in connection with the interpretation and administration of this Plan
unless attributable to his or her own bad faith or willful misconduct. The
Committee may employ legal counsel, consultants, actuaries and agents as it may
deem desirable in the administration of the Plan and may rely on the opinion of
such counsel or the computations of such consultant or other agent. The
Committee shall have the authority to delegate some or all of the powers and
responsibilities under the Plan and the Trust Agreement to such person or
persons as it shall deem necessary, desirable or appropriate for administration
of the Plan. The Committee shall provide for the keeping of written minutes of
its actions hereunder which shall be reviewed by the legal counsel engaged by
the Committee prior to their finalization.

         8.2 EXPENSES. The costs of the establishment of the Plan and the
adoption of the Plan by Employer, including but not limited to legal and
accounting fees, shall be borne by Employer. The expenses of administering the
Plan and the Trust shall be borne by the Trust unless the Employer elects in its
sole discretion to pay some or all of those expenses; provided, however, that
Employer shall bear, and shall not be reimbursed by, the Trust for any tax
liability of Employer associated with the investment of assets by the Trust.

                                        9

                            GENERAL AND MISCELLANEOUS

         9.1 RIGHTS AGAINST EMPLOYER. Except as expressly provided by the Plan,
the establishment of this Plan shall not be construed as giving to any Employee
or to any person whomsoever, any legal, equitable or other rights against the
Employer, or against its officers, directors, agents or stockholders, or as
giving to any Employee or Beneficiary any equitable or other interest in the
assets, business or shares of Employer stock or giving any Employee the right to
be retained in the employment of the Employer. Neither this Plan or any action
taken hereunder shall be construed as giving to any Employee the right to be
retained in the employ of the Employer or as affecting the right of the Employer
to dismiss any Employee. Any benefit paid or payable under the Plan shall not be
deemed salary or other compensation for the purpose of computing benefits under
any employee benefit plan or other arrangement of the Employer for the benefit
of its Employees, but deferrals under the Plan shall be deemed salary or other
compensation for the purpose of computing benefits under other employee benefit
plans or other arrangements of the Employer for the benefit of its Employees to
the extent provided under the terms of such other plans or arrangements.

         9.2 ASSIGNMENT OR TRANSFER. No right, title or interest of any kind in
the Plan shall be transferable or assignable by any Employee or Beneficiary or
be subject to alienation, anticipation, encumbrance, garnishment, attachment,
execution or levy of any kind, whether voluntary or involuntary, or

                                       69
<PAGE>   10
be subject to the debts, contracts, liabilities, engagements, or torts of the
Employee or Beneficiary. Any attempt to alienate, anticipate, encumber, sell,
transfer, assign, pledge, garnish, attach or otherwise subject to legal or
equitable process or encumber or dispose of any interest in the Plan shall be
void.

         9.3 SEVERABILITY. If any provision of this Plan shall be declared
illegal or invalid for any reason, said illegality or invalidity shall not
affect the remaining provisions of this Plan but shall be fully severable, and
this Plan shall be construed and enforced as if said illegal or invalid
provision had never been inserted herein.

         9.4 CONSTRUCTION. The article and section headings and numbers are
included only for convenience of reference and are not be taken as limiting or
extending the meaning of any of the terms and provisions of this Plan. Whenever
appropriate, words used in the singular shall include the plural or the plural
may be read as the singular. When used herein, the masculine gender includes the
feminine gender.

         9.5 GOVERNING LAW. The validity and effect of this Plan and the rights
and obligations of all persons affected hereby shall be construed and determined
in accordance with the laws of the State of California unless superseded by
federal law.

         9.6 PAYMENT DUE TO INCOMPETENCE. If the Committee receives evidence
that an Employee or Beneficiary entitled to receive any payment under the Plan
is physically or mentally incompetent to receive such payment, the Committee
may, in its sole and absolute discretion, direct the payment to any other person
or trust which has been legally appointed by the courts or to any other person
determined by the Employer to be a proper recipient on behalf of such person
otherwise entitled to payment, or any of them, in such manner and proportion as
the Employer may deem proper. Any such payment shall be in complete discharge of
the Employer's obligations under this Plan to the extent of such payment.

         9.7 TAXES. The Employer may withhold from any benefits payable under
this Plan, all federal, state, city or other taxes as shall be required pursuant
to any law or governmental regulation or ruling.

         9.8 ATTORNEY'S FEES. Employer shall pay the reasonable attorney's fees
incurred by any Employee in an action brought against Employer to enforce
Employee's rights under the Plan, provided that such fees shall only be payable
in the event that the Employee prevails in such action.

         9.9 PLAN BINDING ON SUCCESSORS/ASSIGNEES. This Plan shall be binding
upon and inure to the benefit of the Employer and its successor and assigns and
the Employee and the Employee's designee and estate.

         The Employer has caused its authorized officer to execute this document
this 28th day of December, 1995.
