PART I

ITEM 1.  BUSINESS

         Cadence Design Systems, Inc. ("Cadence" or the "Company") develops,
markets, and supports electronic design automation ("EDA") software products
that automate, enhance and accelerate the design and verification of integrated
circuits ("ICs") and electronic systems.  Cadence's product lines are composed
of suites of software packages or tools, integrated through Cadence's
proprietary software architecture.

         Cadence was formed as a  result of the merger of SDA Systems, Inc.
("SDA") into ECAD, Inc. ("ECAD") in May 1988.  ECAD commenced operations in
1982.  SDA commenced operations in 1983.  The Company's name was changed to
Cadence Design Systems, Inc. in June 1988.  In March 1989, Cadence acquired
Tangent Systems Corporation ("Tangent").  In December 1989, Cadence merged with
Gateway Design Automation Corporation ("Gateway"), a leading EDA supplier of
digital logic simulation software.  In July 1990 Cadence merged with Automated
Systems, Inc. ("ASI"), a company that marketed products and services related to
the design and manufacture of electronic printed circuit boards ("PCBs") to the
aerospace, defense, computer and telecommunications industries.  In December
1991 Cadence merged with Valid Logic Systems Incorporated ("Valid"), a company
that developed and supported EDA software used to design electronic systems,
PCBs and applications for electronic product designs involving advanced
packaging technology such as hybrids and multi-chip modules ("MCMs").  In June
1993 Cadence acquired the business and certain assets of Comdisco Systems, Inc.
("Comdisco") a subsidiary of Comdisco, Inc. Comdisco develops, markets and
supports digital signal processing software products in the electronic systems
applications area.  In December 1993 the Company sold its ASI division and
reported the operating results of ASI as discontinued operations for all prior
years.

         Valid had acquired two companies by merger in February 1989:
Integrated Measurements Systems, Inc. ("IMS"), a company that manufactured and
marketed verification systems used in testing prototype application specific
integrated circuits ("ASICs"), and Analog Design Tools, Inc. ("ADT"), a
supplier of computer-aided engineering ("CAE") software for the design of
analog electronic circuits.

THE ELECTRONIC PRODUCT DEVELOPMENT CYCLE

         ELECTRONIC DESIGN AUTOMATION EDA refers to the use of engineering
software to design electronic circuits and systems.  A critical and enabling
technology for the global electronics industry,  EDA allows engineers to
develop complex and high quality electronic products within accelerated
time-to-market schedules. EDA software is one of the key forces driving
electronics innovation and production.
         Virtually all complex computer, telecommunication, aerospace and
semiconductor projects depend on advanced EDA solutions to handle the large
amounts of data associated with these designs. In addition, the short product
life cycles of consumer electronics products depend on the accelerated design
schedules that EDA software allows. EDA software can literally cut months from
a production schedule, allowing design teams to complete projects in a
timeframe that would be impossible if done manually.
         Electronics manufacturing has a synergistic relationship with EDA.
Without EDA simulation software to verify design performance, the design
quality required for profitable high volume production of ICs and PCBs would be
compromised.  EDA technology has also enabled the quick production time and
enormous market growth of semi-custom circuits and subsystems such as ASICs,
Programmable Logic Devices ("PLDs"), Field Programmable Gate Arrays ("FPGAs")
and MCMs.
         EDA systems address two major functions in the electronic product
development cycle:  electrical design, often referred to as CAE, and physical
design, often referred to as computer-aided design ("CAD").  Together, CAE and
CAD address the major phases in the design of electronic systems, PCBs, MCMs,
ASICs, PLDs, FPGAs and full-custom ICs.

         CAE DESIGN PROCESSES  The electrical design process involves design
description, model development and simulation of the design's behavior and
timing performance. Additional design automation technologies, such as
architectural design and logic and test synthesis, can simplify the design
entry process; IC floorplanning can provide greater accuracy in simulation.
         Design description (called design entry, design capture or schematic
capture) is the first step in the electronic design process. To handle the
complexity of large designs, design entry often consists of several levels of
design description.  At the highest level of abstraction, a design can be
expressed in a behavioral description, a convention that allows engineers to
describe large and complex designs quickly.  Behavioral design description
typically involves the use of equations, or a special design description
language called a Hardware Description Language ("HDL").
         For digital designs, the most common HDLs are Verilog(R) HDL, a
language developed by Cadence that is now in the public domain, and VHDL, a
language standardized and backed by the U.S. Department of Defense and
supported by Cadence as well as many other EDA vendors.  A similar standard is
emerging for analog design. Cadence is developing an analog hardware
description language ("AHDL") which it will seek to make an industry-standard.
         Much as a sketch is detailed into a blueprint before building a house,
behavioral descriptions must be detailed into lower-level descriptions (also
called structural designs) before the IC or PCB can be manufactured. This
process can be done manually, or in an automated fashion using a process called
logic synthesis and a software tool such as the Cadence Synergy(TM)
synthesizer.  In structural design, the engineer specifically defines
components, their interconnections, and associated physical properties. This
description can be the text file produced by logic synthesis, or a graphical
drawing 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 symbols and 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 to verify the design electronically before it is
manufactured, enabling engineers to explore design alternatives quickly and to
catch costly design errors before the design is manufactured.  Simulation can
be performed with different levels of design description:  behavioral,
structural and mixed-level.  These levels allow designers to test their design
concept, actual structure and performance, and a combination of concept and
structure.  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, or are provided by third-parties such as
ASIC vendors or independent modeling companies that have certified their
libraries for use with Cadence's simulation products.

         When the functionality and timing are determined to be correct, the
engineer generates a netlist.  A netlist is a non-graphic description, in list
form, of all design components and interconnects.  The netlist is the link
between the CAE design environment and the CAD process.

         CAD DESIGN PROCESSES  An electronic product's physical design process
varies depending on whether the final product is a full-custom IC, an ASIC or a
PCB.  However, the physical design process typically includes the placement of
devices or components, electrical routing or wiring between those devices and
components, analysis of the layout to check for compliance with design rules
and performance specifications and the generation of data for use in
manufacturing and test activities.

         If the design is a full custom IC, the process includes chip-level
architectural design, creation of cells and blocks, floorplanning, placement,
routing and compaction of the cells/blocks, analysis of conformance to
electrical and physical design rules, analysis of wire lengths, load factors
and timing performance, and generation of mask data for chip fabrication.  If
the design is produced as a PCB or MCM incorporating off-the-shelf components,
full custom ICs and/or ASICs, physical design typically includes floorplanning
and pre-placement of critical components, automatic or interactive component
placement, analysis of thermal conditions and high-frequency transmission line
characteristics, analysis of testability and generation of test documentation,
pre-manufacturing clean-up or "glossing" of the board design, and generation of
a wide range of manufacturing data and artwork.

CADENCE'S EDA PRODUCT FAMILY

         Cadence's full line of integrated EDA software solutions has been
developed to support engineers at two levels. At one level, individual
engineers need solutions to solve their specific design needs. A second level
is to support teams of engineers working on larger projects. These engineers
need to share information across the entire company and can do so effectively
with a variety of solutions from Cadence.

         Cadence offers a full line of integrated EDA solutions for three basic
design areas:  IC design for digital, analog and mixed-signal devices; system
design for both digital and analog systems; and ASIC design, particularly for
high-performance sub-micron ASICs.

         These three areas include solutions for the electrical and physical
design of all types of systems, subsystems, and ICs, including PCBs, MCMs,
hybrids, ASICs, PLDs, FPGAs, and full custom and semi-custom ICs.

         The major advantages of Cadence products are in the areas of design
methodologies and 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, the Cadence design
environment can be expanded to include additional Cadence tools or third-party
tools.  Customizing environments can be handled through Cadence's Spectrum
Services Group, responsible for working with customers to define and implement
design environments optimized for customer project or product needs.

PRODUCT STRATEGY AND PRODUCTS
     Cadence's goal is to provide technology that accelerates the creation of

         OPEN ENVIRONMENT  Cadence pioneered the ability to link and manage a
variety of design tools under a consistent graphical user interface with the
introduction of its Design Framework(TM) in 1985.  In 1990 Cadence delivered
Design Framework II, so that designers can work with multiple tools more
efficiently. Through its communication and design management features, Design
Framework II also improves project and data management, critical for today's
large designs and design teams.
         Design Framework II gives users an easy-to-use EDA software system,
which can easily be customized, combined with third party tools, and ported to
new computer platforms as they become available.
         Cadence's software  operates on industry standard workstations from
Digital Equipment Corporation, Hewlett-Packard/Apollo, International Business
Machines Corporation and Sun Microsystems, Inc. Cadence believes that it is
well positioned to port its systems quickly to other UNIX-based workstations
that may gain broad customer acceptance in the future.
         The CAD Framework Initiative (CFI), a standards committee comprised of
EDA vendors and customers, has developed a reference architecture as an initial
step towards a universal framework definition. As a founding member, Cadence
works closely with CFI to develop this standard, and is advancing Design
Framework II to adhere to CFI's evolving guidelines.

         ASIC DESIGN  Cadence helped pioneer the use of top-down design by ASIC
designers with its Verilog-XL simulator and Verilog(R) HDL design language.
Building on what is now the most broadly used top-down method in the industry,
Cadence offers a complete and production- proven top-down design system.
         Included is a flexible environment  with Composer(TM) mixed-level
design entry using either Verilog HDL or VHDL; large-capacity, high-
performance logic synthesis and optimization with the Synergy  and
Optimizer(TM) synthesis software; fully integrated mixed-level logic simulation
with Verilog-XL(TM) and Leapfrog(TM) VHDL verification tools;  and the
Preview(TM) floorplanner that enable the sharing of consistent timing data from
design entry through place and route. Completing the ASIC design process is
Cadence's Gate Ensemble place and route system.  A new series of
design-for-test tools, offering advanced test synthesis and test pattern
generation capabilities, helps to shorten ASIC design cycles and improve
yields.
         In addition, Cadence's extensive list of over 185 ASIC libraries and
endorsements from major ASIC vendors help ensure a production path for the most
complex, leading-edge ASIC designs.

MARKETING AND CUSTOMERS
         CUSTOMERS AND MARKETING STRATEGY  Cadence's customers and target
markets include computer manufacturers, consumer electronics companies, defense
electronics companies, merchant semiconductor manufacturers, ASIC foundries and
telecommunications companies.  In addition, Cadence licenses its products to
international distributors in certain countries (see "International Sales"
below in this "Business" section).  In 1993, 1992 and 1991 one customer,
Cadence's distributor in Japan, Innotech Corporation ("Innotech"), accounted
for 13%, 14% and 13% of total revenue, respectively.

         Cadence's principal marketing objectives are:
         o  Offer high quality, complete and integrated design solutions
         o  Provide best-in-class technologies in critical design areas
         o  Deliver a standards-driven, open design environment
         o  Utilize Cadence's worldwide resources to solve customers' complex 
            design challenges and serve global customers

         CUSTOMER SUPPORT  Cadence's support group helps tailor new tools to a
customer's existing design environment, train designers on how to best utilize
their EDA software and provide ongoing software updates to enhance product
capabilities. The backbone of the global customer support process 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





                                       5
<PAGE>   8
available to address customer applications issues as well as provide links
between customers and Cadence's product developers.

         CADENCE SPECTRUM SERVICES  Customizing design automation systems can
require a major time and resource investment from the customer.  Spectrum
Services provides a structured consultative approach to analyzing the design
process. After an extensive review of a customer's business and technical
objectives and design processes, a comprehensive plan is developed for an
advanced custom design environment. By integrating Cadence's solutions with the
customer's software tools and third-party and custom-designed tools and
augmenting the software with expert advice on streamlining the design process,
customers benefit from a custom optimized design environment.

         CUSTOMER PARTNERSHIPS  Cadence has established close working
relationships with a number of semiconductor manufacturers and electronic
systems 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 begin after
collaboration with a Cadence customer/partner.
         There are presently several variations of Cadence partnerships:  four
groups of technology partnerships (involving Cadence's IC, HDL, Systems Design
and Systems Physical Design Groups, respectively) and a fifth group that
focuses on development of specific products ("Product Development
Partnerships").

         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.

     INDUSTRY ALLIANCES  Cadence cooperates with other design automation
vendors to deliver full-scope technology to its customers. Through Cadence's
Connections(TM) Program, participating companies can integrate their products
and technologies more easily into Cadence's design framework. This provides
customers with the flexibility to mix and match third-party and proprietary
tools to specifically meet their design automation needs. Today over 70
companies have integrated their tools into Cadence's design framework.

     UNIVERSITY SOFTWARE PROGRAM  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.

SALES

            As of December 31, 1993, Cadence had 796 employees engaged in field
sales and sales support, representing approximately 32% of its total employees.
Cadence's sales people present 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.

            NORTH AMERICAN SALES  In the domestic market Cadence uses a direct
sales force, utilizing both sales people and applications engineers in each
territory to license its products.  As of December 31, 1993, Cadence had 419
regional sales people and applications engineers licensing and supporting
Cadence's products in the United States and Canada.  Cadence maintains domestic
sales and support offices at various locations across the United States.

            INTERNATIONAL SALES  In Europe and Asia Cadence markets and
supports its products primarily through 12 majority owned subsidiaries, which,
as of December 31, 1993, employed 86 salespeople and 291 other sales and
support personnel.

            Cadence licenses its products in Japan through three distributors:
Innotech, Kanematsu Electronics and Sony Tektronics.  Cadence's systems
products are marketed in Japan through a wholly-owned subsidiary and, until
1992, through a distributor, CIC, Inc.  In March 1992 Cadence reached an
agreement to acquire CIC, Inc. and consolidated its systems product marketing
in Japan utilizing its subsidiary in Japan, Cadence Design Systems K.K.
("Cadence K.K.").

            Cadence also serves its international customers through a
manufacturer's representative in Europe, European Silicon Structures B.V.
("ES2").  The Company also uses distributors in various countries.  In
Singapore, Hong Kong, Brazil, Australia, India and The People's Republic of
China, Cadence uses CAD/CAM Systems, Modern Devices Ltd., Quick Chip Eng. E.
Projectos Ltd., Cadence Design Systems Pty Ltd., Wipro Information Technology
and IMAG Industries, Inc. and ReMA Ltd., respectively, as its distributors.

            Revenue from international sources was $183.6 million, $215.4
million and $197.6 million or approximately 50%, 51% and 52% of total revenue
for the years ended December 31, 1993, 1992 and 1991, respectively.

            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.
In light of the large portion of Cadence's revenue derived from international
sales, if the dollar strengthens in relation to the Japanese yen or certain
European currencies, Cadence's revenue from international sales may be
adversely affected.  Cadence enters into forward exchange contracts to reduce
the impact of foreign currency fluctuations resulting from transaction gains
and losses.  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.

            Foreign subsidiaries' marketing and support expenses are incurred
in local currency and license fees paid by the subsidiaries to Cadence are paid
in local currency or U.S. dollars.  Cadence is subject to the currency
conversion risks inherent in international transactions.  It is Cadence's
policy to manage and minimize its foreign exchange risks.

SERVICE AND SUPPORT

            STANDARD SERVICE AND SUPPORT  Cadence believes that customer
support is a key factor in successfully marketing EDA products and generating
repeat orders.  A majority of Cadence's customers have purchased one-year
renewable maintenance contracts.

            Product maintenance contracts entitle the customers to product
updates, documentation and ongoing support.  Cadence tracks all service reports
using an on-line database that provides a mechanism for tracking progress in
solving any reported problem from first report to final software solution.

            ENHANCED SERVICE AND SUPPORT  Installing a new design automation
system, tailoring it to a customer's design environment and training designers
in the efficient use of this new system requires a major time and resource
investment from the customer.  In response to customer requests, Cadence has
developed an enhanced consulting service capability.  The Cadence consulting
services team is a group of Cadence employees whose services can be retained by
customers to provide a wide range of engineering activities from specialized
training to custom programming projects or contract  design.  These services
are intended to assist customers in becoming  productive quickly through use of
Cadence's products, thereby improving customer satisfaction and increasing the
likelihood of follow-on sales.

PRODUCT DEVELOPMENT AND ENGINEERING

            As of December 31, 1993, Cadence's product development was
performed by 750 employees, 476 employees located at its research and
development facilities in San Jose, Foster City, Santa Cruz and San Diego,
California, 106 employees in Chelmsford, Massachusetts, 59 employees in India,
13 employees in Taiwan, 15 employees in Lawrence, Kansas, 2 employees in Ohio
and 5 employees in Albany, New York.  The development group includes experts in
database structures and industry specific algorithm technology.  In June 1990,
the Company entered into a joint venture  ("EuCAD") as majority owner with ES2.
During 1992, the Company acquired the minority interest in the joint venture.
EuCAD has 26 employees in the U.K. and 3 employees in France and  specializes
in research and development activities in the EDA and ASIC design markets.  The
Company also has 45 employees in Beaverton, Oregon at its IMS subsidiary.

            For the years ended December 31, 1993, 1992 and 1991 Cadence's
research and development expenses were approximately $84.3 million, $81.2
million and $84.3 million (before capitalizing approximately $15.2 million,
$14.7 million and $16.2 million of software development costs in 1993, 1992 and
1991), respectively.  Cadence began capitalizing certain of its software
development costs in 1986 in accordance with Statement of Financial Accounting
Standards No. 86.  See Note 3 of Notes to Consolidated Financial Statements at
December 31, 1993 for a more complete description of Cadence's capitalization
of certain software development costs.

            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.

COMPETITION

            Cadence competes with a number of companies in each of Cadence's
tool categories, as well as with internal CAD development groups of potential
customers.  The EDA  software industry is characterized by rapid technological
change and is intensely competitive.  In Cadence's opinion, the principal
competitive factors in its markets include performance, ease of use, breadth of
tool offering, open system architecture, software portability, pre-sales and
post-sales support and price.

PROPRIETARY RIGHTS

            Cadence relies principally upon a combination of copyright and
trade secret laws and license agreements to protect Cadence's proprietary
interest in its products.   Cadence's products are generally licensed to end
users pursuant to a license agreement that restricts the use of the products to
the customer's internal purposes.  Cadence protects the source code version of
its products as a trade secret and as an unpublished copyrighted work.  Cadence
has made portions of its source code available to certain customers  under very
limited circumstances, subject to confidentiality, use and other restrictions.
Despite these precautions, it may be possible for third parties to copy aspects
of Cadence's products or to obtain and use information that Cadence regards as
proprietary without authorization.  In addition, effective copyright and trade
secret protection for software products may be unavailable in certain foreign
countries.

            Cadence believes that patent, trade secret and copyright protection
are less significant to Cadence's success than factors such as the knowledge,
ability and experience of Cadence's personnel, new product development,
frequent product enhancements, name recognition and ongoing reliable product
maintenance.  Cadence does not believe that its products or processes infringe
on existing proprietary rights of others.

            DRACULA(R), Verilog(R), Prance(R), Verifault-XL(R) and Thermax(R)
are registered trademarks of Cadence and substantially all of the other Cadence
product and product family names used herein are trademarks of Cadence.

MANUFACTURING AND BACKLOG

            Cadence's software production operations consist of configuring the
proper version of a product, recording it on magnetic tape or other recording
media and producing user manuals and other documentation.  Shipments are
generally made within two weeks of receiving an order.  In light of the short
time between order and shipment of Cadence's products, Cadence generally has
relatively little backlog at any given date.

            Cadence's product line includes a series of design verification
systems offered by IMS.  Logic Master is a family of design verification
systems designed to work with most computer systems, workstations, or terminals
to receive and execute test commands and report the results of test procedures.
These systems are designed to match varying customer requirements.  Generally,
they differ from one another as to speed, size of the device to be verified,
flexibility in the number and variety of applications in which a system can be
used and price.

EMPLOYEES

            As of December 31, 1993, Cadence employed 2,476 persons, including
1,449 in sales, marketing, support and manufacturing activities, 750 in product
development and 277 in management, administration and finance.  Of these
employees, 1,949 were located in the United States and 527 were located in 15
other countries.  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

            Cadence leases approximately 692,000 square feet of facilities
comprised of four buildings located at 535-575 River Oaks Parkway (the "555
Facility"), three buildings at Seely Road and three buildings at Plumeria Drive
in San Jose, California for an annual rental of approximately $10,600,000.
Cadence also leases approximately 100,000 square feet of facilities in
Chelmsford, Massachusetts at an annual rate of approximately $450,000.  Cadence
leases additional facilities for its sales offices in the United States and
various foreign countries, and research and development facilities in  San
Diego, Foster City and Santa Cruz, California, Lawrence, Kansas, Albany, New
York, United Kingdom, France, Taiwan and India at an aggregate annual rental of
approximately  $7,000,000.

            Cadence leases design center facilities in Blue Bell, Pennsylvania
and Torrance, California, of approximately 11,700 and 13,700 square feet,
respectively, at a combined annual rate of approximately $500,000.  Cadence has
contracted for the early termination of the Torrance facility lease and expects
this transaction will close by April 1994 for approximately $600,000.  In
connection with its sales of ASI, Cadence has entered into a sublease agreement
with ASI for the rental of the Blue Bell facility.

            Cadence also leases approximately 75,000 square feet in a building
in Beaverton, Oregon, at a current annual rental of approximately $540,000,
which houses manufacturing, engineering, marketing and administrative
operations for its IMS subsidiary.

            During June 1989 Cadence acquired a 49% interest as a limited
partner in a real estate partnership.  Also in 1989, the Company signed
agreements to lease the four buildings of the 555 Facility from the limited
partnership that is the owner of the 555 Facility for a period of ten years.
During June 1991 the Company acquired a 46.5% interest as a limited partner in
an additional real estate partnership, and signed agreements to lease upon
completion of construction three buildings proximate to the 555 Facility in San
Jose, California from the limited partnership for a period of fifteen years,
which commenced during the second quarter of 1992.  During June 1991 the
Company acquired an 80% interest in a third real estate partnership which has
purchased land for future expansion.  This third partnership is consolidated in
the accompanying financial statements.  In March 1994 the Company acquired all
third-party interests in two real estate partnerships in which it is a 46.5%
and 80% limited partner, respectively, for approximately $9 million in cash and
the assumption of a secured construction loan of approximately $23.5 million.
The Company expects it will refinance the construction loan with permanent
financing when it comes due in June 1994, although it may elect to pay off the
construction loan with its cash reserves.

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

ITEM 3.      LEGAL PROCEEDINGS

             Stockholder class action lawsuits were filed against the Company
and certain of its officers and directors in the United States District Court
for the Northern District of California, San Jose Division, on April 8 and 9,
1991.  The suits were subsequently consolidated into a single lawsuit and the
class period changed to include purchasers of the Company's common stock during
the period from October 18, 1990 through April 3, 1991.  The lawsuit alleges
violation of certain federal securities laws by maintaining artificially high
market prices for the Company's common stock through alleged misrepresentations
and nondisclosures regarding the Company's financial condition.  The plaintiff
in the suit seeks compensatory damages unspecified in amount.  On June 2, 1993
the District Court granted in part and denied in part the Company's motion to
dismiss the complaint in the class action originally filed in April 1991.  The
effect of the ruling was to limit the class period to include purchasers of the
Company's common stock between January 29, 1991 and April 3, 1991.  Trial of
this matter is scheduled to commence on August 8, 1994.  The Company is
vigorously defending against the litigation.

             On March 23, 1993 a separate class action lawsuit was filed
against the Company and certain of its directors and officers in the United
States District Court, Northern District of California, San Jose Division.  Two
additional complaints, identical to the complaint filed on March 23, 1993
except for the identities of the plaintiffs, were filed later in March and in
April 1993.  All three complaints were consolidated into a single lawsuit which
seeks unspecified damages on behalf of all purchasers of the Company's common
stock between October 12, 1992 and March 19, 1993.  The lawsuit alleges
violation of certain federal securities laws by maintaining artificially high
market prices for the Company's common stock through alleged misrepresentations
and nondisclosures regarding the Company's financial condition.  On November
18, 1993, the District Court granted the Company's motion to dismiss the 1993
complaint.  The effect of the ruling was to dismiss the complaint except as to
a statement allegedly made on January 28, 1993, but plaintiffs were granted
leave to further amend their complaint.  The Company is vigorously defending
against the litigation.

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

      Cadence (the "Company") designs, develops, markets and supports
electronic design automation ("EDA") software products primarily used to
automate, enhance and accelerate the design, verification and testing of
integrated circuits, electronic systems and printed circuit boards ("PCBs").

      In December 1991 the Company merged with Valid Logic Systems Incorporated
("Valid").  Valid commenced operations in 1981 and was involved in the
development, marketing and support of EDA products primarily used to design
electronic systems and PCBs.  The merger was accounted for by the pooling of
interests method and all financial information prior to the merger has been
restated to combine the results of the Company and Valid.  In connection with
the merger, the Company recorded $49.9 million of restructuring costs and $1.7
million of merger costs in the fourth quarter of 1991.

      In June 1993 the Company acquired the business and certain assets of
Comdisco Systems, Inc. ("Comdisco"), a subsidiary of Comdisco, Inc.  Comdisco
develops, markets and supports digital signal processing software products in
the electronic systems applications area. The acquisition was accounted for as
a purchase.  Accordingly, the results of Comdisco from the date of the
acquisition forward have been recorded in the Company's consolidated financial
statements.

      In December 1993 the Company sold its Automated Systems ("ASI") division.
ASI manufactures and provides design services for complex printed circuit
boards. The operating results of ASI have been reported as discontinued
operations in the consolidated statements of income for all years presented.

(1)   The Company capitalizes software development costs in accordance with
      SFAS No. 86.  Total research and development expenses incurred prior to
      capitalization represented 23%, 19% and 22% of total revenue for 1993,
      1992 and 1991, respectively.  The percentage change from 1992 to 1993 and
      from 1991 to 1992 was an increase of 4% and a decrease of 4%,
      respectively, on a pre-capitalization basis.

Revenue

             Total revenue was approximately $368.6 million, $418.7 million and
$379.5 million for the years ended December 31, 1993, 1992 and 1991,
respectively.  Total revenue decreased approximately $50.1 million for the year
ended December 31, 1993 as compared to the prior year and increased
approximately $39.2 million in 1992 as compared to 1991.  The decrease in total
revenue in 1993 was primarily due to a $74.0 million decrease in product
revenue due to weak economic conditions in certain areas and lower sales volume
for the Company's products, as well as a shift in the Company's systems product
strategy.  This decrease in product revenue was offset somewhat by the
acquisition of Comdisco.  While product revenue decreased in 1993, maintenance
revenue increased by  $23.9 million due to increased focus on customer
renewals, combined with a larger customer base.   The growth in total revenue
in 1992 compared to 1991 was comprised of  $22.9 million in product revenue due
to increased demand for the Company's products, including the new Valid
products as a result of the merger, and improved economic conditions in 1992 as
compared to 1991, and a $16.3 million increase in maintenance revenue.

             Maintenance revenue continued to increase each year as the
Company's installed base of products has increased, growing by approximately
$23.9 million in 1993 compared to 1992 and by approximately $16.3 million in
1992 compared to 1991. As a percentage of total revenue, maintenance revenue
has grown over the last three years from approximately 23% to approximately 35%
of total revenue.  The increase in maintenance revenue as a percentage of total
revenue is due in part to the Company's continued effort toward obtaining
customer renewals of maintenance coverage as well as the decrease in total
product revenue in 1993.

             Revenue from international sources was approximately $183.6
million, $215.4 million and $197.6 million or 50%, 51% and 52% of total revenue
for each of the three years ended December 31, 1993, 1992 and 1991,
respectively.  The decrease in 1993 was principally related to decreased sales
volume in Japan.  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
restrictions, currency conversion risks, limitations on repatriation of
earnings and reduced protection of intellectual property rights.  Due to the
continuing adverse business conditions in Japan, the Company has experienced
and  can expect to experience a reduced level of activity from this important
market.  A continued low level or further reduction of orders from Japan could
have a material adverse impact on the Company's results of operations.

Cost of Revenue

             Total cost of revenue was approximately $89.4 million, $94.0
million and $87.6 million for the years ended December 31, 1993, 1992 and 1991,
respectively.  Total cost of revenue decreased $4.6 million in 1993 compared to
1992 and increased $6.4 million in 1992 compared to 1991.  The decrease in 1993
consisted of a $2.5 million decrease in product cost of revenue due to the
decrease in product revenue and related costs, reduced costs due to restructure
actions including related headcount reductions as well as the discontinuance in
1992 of sales of third- party hardware.  This decrease was slightly offset by
an increase in cost of product associated with the newly acquired Comdisco
operations and a $4.0 million  increase in amortization of software development
costs, purchased software and other intangibles.  Cost of maintenance also
decreased $2.1 million in 1993 as compared to 1992 even though revenue
increased due to the streamlining of the maintenance renewal process which
includes a more cost-effective update program and lower cost media.   The
increase in total cost of revenue in 1992 as compared to 1991 consisted of an
$11.7 million increase in cost of product, which was offset by a $5.4 million
decrease in cost of maintenance.  The increase in cost of product was primarily
due to an increase in royalties of approximately $2.4 million and other related
software product costs.  The increase in software costs in 1992 was primarily a
result of the expansion-related increase in personnel and capital expenditures
in the Company's operations departments, which include software tape
duplication, technical documentation and support, training and consulting
services.  The decrease in cost of maintenance in 1992 was primarily due to
post-merger restructure and efficiencies, including the reduction of personnel
and other duplicate costs in 1992 due to the merger of the Company with Valid,
streamlining of the maintenance renewal process and a decrease in hardware
maintenance contracts and costs related to Valid.   As a percentage of total





                                       17
<PAGE>   20
revenue, cost of maintenance revenue has remained in the range of approximately
4% to 6% and cost of product revenue has been at approximately 17%  to 20%.

Gross Margin

             Gross margin was 76%, 78% and 77% for the years ended December 31,
1993, 1992 and 1991, respectively.

Marketing and Sales

             Marketing and sales expenses increased $1.2 million in 1993
compared to 1992 and $11.8 million in 1992 compared to 1991.  The increase in
1993 is primarily due to increased costs associated with the acquired Comdisco
operations.  This increase was partially offset by reduced costs related to
restructure actions, including headcount reduction.  The increase in 1992 was
due to the establishment and continued growth of foreign subsidiaries and
domestic field offices, and increased personnel and related expenses.  As a
result of the merger with Valid, there were a number of duplicate sales
locations which were consolidated during 1992.  Notwithstanding this, during
1992 the Company continued to focus on expanding its selling efforts.  The
costs associated with the consolidation of sales offices were included in the
restructuring costs recorded in 1991.  Marketing and sales expenses have
increased as a percentage of revenue from 39% in 1991 to 43% in 1993.  The
higher percentage in 1993 is due primarily to the decrease in total revenue in
1993.

Research and Development

             Total research and development expenditures incurred prior to
capitalization of software development costs increased 4% in 1993 as compared
to 1992 and decreased 4% in 1992 as compared to 1991, an increase of
approximately $3.1 million and a decrease of approximately $3.2 million,
respectively.  The increase in 1993 is primarily due to increased expenses due
to the addition of Comdisco's operations.  The decrease in total research and
development expenditures in 1992 compared to 1991 is due primarily to
post-merger restructure and efficiencies, including the reduction of personnel
and other duplicate costs in 1992 related to the merger with Valid.  Prior to
the deduction for capitalization of software development costs, research and
development expenses comprised approximately 23%, 19% and 22% of total revenue
or approximately $84.3 million, $81.2 million and $84.3 million for the years
1993, 1992 and 1991, respectively.  The increase as a percentage of revenue in
1993 is primarily due to the decrease in total revenue in 1993 as compared to
1992.  The decrease as a percentage of revenue in 1992 as compared to 1991 is
due primarily to the elimination of duplicate costs in 1992 as a result of the
merger with Valid.  The Company capitalized approximately $15.2 million, $14.7
million and $16.2 million of software development costs in the years 1993, 1992
and 1991, respectively, which represented approximately 18%, 18% and 19% 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

             General and administrative expenses increased approximately $4.9
million in 1993 compared to 1992 and decreased approximately $2.2 million in
1992 compared to 1991. The increase in 1993 is due to the addition of
Comdisco's operations, increased bad debt expense due to the write-off of
uncollectible accounts, increased professional services and employee-related
expenses. The decrease in 1992 was due primarily to the result of post-merger
efficiencies, including the reduction of personnel and related expenses and
duplicate facilities in 1992 as a result of the merger with Valid.  As a
percentage of total revenue, general and administrative expenses have been in
the range of approximately 8% to 10%.  The higher percentage in 1993 is
partially due to the decrease in total revenue in 1993.





                                       18

Restructuring Costs

             In March 1993 the Company recorded restructuring costs of $13.5
million associated with a planned restructure of certain areas of sales,
operations and administration due to business conditions.  The restructuring
charge primarily reflects costs associated with excess facilities, the
write-off of software development costs and purchased software and intangibles
and employee terminations resulting from lower revenue levels.

             In the fourth quarter of 1991 the Company recorded restructuring
costs of approximately $49.9 million associated with the merger of Valid with
the Company.  This amount included accruals for severance and payroll-related
payments, costs of closing excess or duplicate facilities and write-offs of
equipment, other assets and capitalized software development costs due to the
overlap of products.

Other Income and Expense

             Interest income was $3.2 million, $3.6 million and $6.2 million
for the years ended December 31, 1993, 1992 and 1991, respectively.  The
decrease in interest income in 1993 and 1992 was primarily due to a decrease in
interest rates which in 1992 was combined with a $20.7 million decrease in cash
and cash investments and short-term investments.  Interest expense was $.7
million, $.9 million and $2.6 million for the years ended December 31, 1993,
1992 and 1991, respectively.  The decrease in 1993 as compared to 1992 is due
to a decrease in capital lease borrowings and other debt obligations.  The
decrease of $1.8 million in 1992 as compared to 1991 was due to the repayment
of $18.5 million in notes payable to banks in 1991.  In addition, the Company
incurred approximately $1.7 million of merger costs in the fourth quarter of
1991 related to the merger of the Company and Valid.

Provision for Income Taxes

         Through December 31, 1992, the Company accounted for income taxes
pursuant to Statement of Financial Accounting Standards ("SFAS") No.  96.
Effective January 1, 1993, the Company retroactively adopted SFAS No. 109,
"Accounting for Income Taxes."  This pronouncement requires, among other
things, recognition of future tax benefits, measured by enacted tax rates,
attributable to (a) deductible temporary differences between the financial
statement and income tax basis of assets and (b) liabilities and tax net
operating loss carryforwards, to the extent that realization of such benefits
is more likely than not.  The adoption of this accounting pronouncement did not
have a material impact on amounts reported in prior years' financial
statements.

         As of December 31, 1993 the Company had gross deferred tax assets of
approximately $67.0 million against which the Company has recorded a valuation
allowance of $54.6 million, resulting in a net deferred tax asset of $12.4
million.  A significant portion of the net operating loss and credit
carryforwards which created the deferred tax asset were generated by Valid
prior to its merger with the Company and by restructure charges recorded as a
result of the merger.  Management has determined, based on the Company's
history of prior operating earnings and its expectations for future years, that
the recorded net deferred tax asset is realizable.  However, no assurances can
be given that sufficient taxable income will be generated in future years for
the utilization of the net deferred tax asset.

         The Company's tax provision for 1993 was zero as a result of the
operating loss in 1993 and the recording of the benefit of certain foreign
withholding and income taxes.

             In 1992 the Company's effective tax rate was 19%.  This rate
reflects the utilization of foreign tax credits, Valid's net operating losses
and temporary items generated in prior years but benefited currently.





                                       19
<PAGE>   22



             The Company provided for income taxes in 1991 even though the
Company reflected a pretax loss.  This provision was primarily attributable to
restructuring costs and foreign tax credits that the Company was not fully able
to benefit for financial statement purposes.

Net Income (Loss) From Continuing Operations

             The net loss from continuing operations  for 1993 was $.6 million
as compared with net income of $55.1 million in 1992 and net loss of $17.1
million in 1991.  The net loss from continuing operations in 1993 was due to a
decrease in product revenue  and $13.5 million recorded for restructuring
costs. The net income in 1992 compared to the net loss in 1991 was partially
due to increased revenue in 1992.  Net income from continuing operations was
also favorably impacted by the post-merger restructure and efficiencies,
including the reduction of personnel and other duplicate costs in 1992 related
to the merger with Valid.   The fourth quarter of 1991 also included $49.9
million of restructuring costs and $1.7 million of merger costs associated with
the merger of the Company and Valid.

Discontinued Operations

             As previously discussed, the Company sold its ASI division in
December 1993 and restated the financial information of prior periods to report
discontinued operations of ASI as a separate line item in the consolidated
statements of income.  The discontinued operations resulted in a loss of $12.2
million, income of $.3 million and a loss of $5.3 million for the years ended
December 31, 1993, 1992 and 1991, respectively.  The loss for 1993 includes
$6.0 million recorded as a loss on disposal, which represents the loss on the
sale of the net assets as well as amounts accrued for estimated costs to be
incurred in connection with the disposal. In addition, the 1993 loss includes
$6.2 million for ASI's operating loss.

Quarterly Results of Operations

             The following table sets forth selected unaudited quarterly
financial information for the Company's last eight quarters.  This unaudited
information has been prepared on the same basis as the audited information and
in management's opinion reflects all adjustments (which include only normal
recurring adjustments) necessary for the fair presentation of the information
for the periods presented.  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 from time to time 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.

             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 period 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 net income
may be impacted significantly by lower revenue.  In addition, the Company's
results of operations for a particular quarter or quarters could be materially
adversely affected by the ultimate resolution of the disputes and litigation
matters discussed in Note 9 of Notes to Consolidated Financial Statements.

             The Company's revenue decreased in each quarter in 1993 as
compared to the same quarter in the prior year.  This decrease was due to weak
economic conditions and reduced demand for the Company's products as well as a
shift in the Company's system product strategy.  In addition, the first quarter
of 1993 included approximately $13.5 million of restructuring costs related to
the Company's planned restructure.

Liquidity and Capital Resources

             The Company raised approximately $10.8 million, $13.8 million and
$14.9 million through the sale of common stock pursuant to employee benefit
plans in 1993, 1992 and 1991, respectively.  The Company purchased $52.2
million of treasury stock and repurchased $10.8 million and $1.8 million of
common stock for the years ended December 31, 1993, 1992 and 1991,
respectively.  In addition, the Company realized approximately $90.7 million,
$40.4 million and $74.7 million in cash provided by operations in 1993, 1992
and 1991, respectively. The Company's principal investing activities consist of
the purchase of property, plant and equipment and the capitalization of
software development costs, which in total were $34.5 million, $45.7 million
and $44.6 million for the years ended December 31, 1993, 1992 and 1991,
respectively.  In addition, the other major component of investing activities
is the change in short-term investments.

             Working capital at December 31, 1993 was $105.0 million compared
with $153.3 million at December 31, 1992 and $119.0 million at December 31,
1991.  The decrease in 1993 as compared to 1992 was primarily due to a decrease
of $30.9 million in accounts receivable primarily due to lower revenue, a $12.8
million increase in deferred revenue and a $7.3 million increase in accrued
liabilities related to restructuring accruals recorded in 1993.   The increase
in 1992 as compared with 1991 was primarily due to a $17.0 million increase in
accounts receivable due to higher revenue, a $21.4 million decrease in accrued
liabilities related to restructuring accruals recorded in 1991 associated with
the Company's merger with Valid and an $11.9 million decrease in deferred
revenue.  These increases were offset by a decrease of $20.7 million in cash
and cash investments and short-term investments.

             Long-term obligations decreased  $1.7 million in 1993 as compared
to 1992 due to a decrease in capital lease borrowings and increased $1.9
million in 1992 as compared to 1991 due to an increase in capital lease
borrowings and other debt obligations.  At December 31, 1993 the Company had
available $15.0 million under equipment lease lines for future capital
expenditures and $17.5 million under two bank lines, which had not been drawn
upon at December 31, 1993  (see Notes 7 and 8 of Notes to Consolidated
Financial Statements for further discussion).

             Anticipated cash requirements in 1994 are payments related to the
purchase of treasury stock, contemplated additions of capital equipment and
restructure costs accrued at December 31, 1993.  Prior to 1993, the Company
authorized the repurchase of up to 2.8 million shares of common stock in the
open market over the next several years to satisfy its estimated requirements
for shares to be issued under its employee stock option and stock purchase
plans.  In April 1993 the Company authorized the repurchase of an additional
4.0 million shares of common stock from time to time in the open market.  In
total, as of December 31, 1993, approximately 5.5 million shares had been
repurchased.  In addition, in February 1994 the Company authorized the
repurchase of an additional 2.9 million shares.  In March 1994 the Company
acquired all third-party interests in two real estate partnerships in which it
is a 46.5% and 80% limited partner for approximately $9 million in cash and the
assumption of a secured construction loan of approximately $23.5 million.  The
Company leases buildings from one of the limited partnerships and the second
limited partnership owns unencumbered land adjacent to the leased property (see
Note 3 of Notes to Consolidated Financial Statements).  The Company expects it
will refinance the construction loan with permanent financing when it comes due
in June 1994, although it may elect to pay off the construction loan with its
cash reserves.  The Company anticipates that current cash balances, cash flow
from operations and unused balances on capital lease lines and lines of credit
will be sufficient to meet its working capital and capital expenditure
requirements for at least the next year.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To 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 31, 1993
and 1992, and the related consolidated statements of income, stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1993.  These financial statements and the schedules referred to below are
the responsibility of the Company's management.  Our responsibility is to
express an opinion on these financial statements and schedules based on our
audits.  We did not audit the financial statements of Valid Logic Systems
Incorporated, a company acquired during 1991 in a transaction accounted for as
a pooling of interests, as discussed in Note 1.  Such statements are included
in the consolidated financial statements of Cadence Design Systems, Inc. and
reflect  total revenues of 40 percent of the consolidated total for the year
ended December 31, 1991.  These statements were audited by other auditors whose
report has been furnished to us and our opinion, insofar as it relates to
amounts included for Valid Logic Systems Incorporated, is based solely upon the
report of the other auditors.

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 and the report of other
auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and the report of other auditors, 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 31, 1993 and 1992, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1993, 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 schedules listed in Item 14.  (a) 2. are
presented for purposes of complying with the Securities and Exchange
Commission's rules and are not part of the basic financial statements.  These
schedules have been subjected to the auditing procedures applied in the audit
of the basic financial statements and, in our opinion, fairly state in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                          CADENCE DESIGN SYSTEMS, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1993

1.    ORGANIZATION OF THE COMPANY

             Cadence Design Systems, Inc. (the "Company") develops, markets and
supports computer-aided design software products that automate, enhance and
accelerate the design, verification and testing of integrated circuits and
complex electronic circuits and systems.

             In December 1991 the Company acquired all of the outstanding
common and preferred stock of Valid Logic Systems Incorporated ("Valid") in
exchange for approximately 10,816,000 shares of the Company's common stock and
86,133 shares of the Company's preferred stock.  Valid was involved in the
design, development, marketing and support of electronic design automation
software products primarily used to design electronic systems and printed
circuit boards ("PCBs").  In connection with the merger, each share of Valid
common and preferred stock was converted into .323 shares of the Company's
common and preferred stock, respectively.  The Company also issued
approximately 199,000 shares of common stock in exchange for an outstanding
warrant to purchase common stock of Valid.  The Company also assumed Valid's
outstanding stock options and all other outstanding warrants.  Each such option
and warrant to purchase one share of Valid common stock was converted into an
option and warrant, respectively, to purchase .323 shares of the Company's
common stock.  The merger was accounted for as a pooling of interests and,
accordingly, the financial statements for periods prior to the merger have been
restated to include the results of Valid.

             In June 1993 the Company acquired the business and certain assets
of Comdisco Systems, Inc. ("Comdisco"), a subsidiary of Comdisco, Inc. in
exchange for 1,050,000 shares of the Company's common stock and a warrant to
purchase 1,300,000 shares of the Company's common stock.  The acquisition was
accounted for as a purchase.  Accordingly, the results of Comdisco from the
date of acquisition forward have been recorded in the Company's consolidated
financial statements.  Comparative pro forma financial information has not been
presented as the results of operations for Comdisco are not material to the
Company's consolidated financial statements for 1993, 1992 and 1991.  The
acquisition costs of $10,903,000 include amounts paid for the net tangible
assets of Comdisco and purchased  software and other intangibles.

2.    DISCONTINUED OPERATIONS

             In December 1993 the Company sold its Automated Systems ("ASI")
division.  ASI was sold for a nominal amount of cash and future royalties
amounting to  5% of gross revenues of ASI for the period from January 1, 1994
through December 31, 2003, up to maximum royalties of $12,000,000.  The
royalties will be recorded in future periods as earned.  The sale of ASI
resulted in a loss on disposal of $6.0 million (the income tax effect of which
was not material).  This loss includes the loss on the sale of the net assets,
as well as amounts accrued for estimated costs to be incurred in connection
with the disposal.  As of December 31, 1993, the Company has recorded $1.4
million in accrued liabilities and $2.0 million in other noncurrent liabilities
for liabilities associated with the discontinued division.  The operating
results of the discontinued division have been reported as discontinued
operations in the consolidated statements of income for all years presented.
The prior year balance sheet has also been adjusted to reflect the net current
assets of ASI as of December 31, 1992 of $4.8 million as a single line item in
other current assets and to reflect the net noncurrent assets of $3.0 million
as a single line item in other assets.  There were no remaining assets related
to ASI on the Company's balance sheet as of December 31, 1993.  Revenue of the
discontinued division was $11,165,000, $15,776,000 and $12,079,000 for the
years ending December 31, 1993, 1992 and 1991, respectively.

3.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

             CONSOLIDATION

             The consolidated financial statements include the accounts of the
Company and its majority-owned subsidiaries after elimination of intercompany
accounts and transactions.  The ownership interest of minority participants in
subsidiaries that are not wholly owned was approximately $725,000 and  $946,000
at December 31, 1993 and 1992, respectively, and is included in other
noncurrent liabilities in the accompanying balance sheets.  Minority interest
income was approximately $134,000 and $196,000 and minority interest expense
was $268,000 for the years ended December 31, 1993, 1992 and 1991,
respectively, and is included in other income and expense in the accompanying
statements of income.

             PROPERTY, PLANT AND EQUIPMENT

             REAL ESTATE PARTNERSHIPS

             During 1989 and 1991 the Company acquired a 49% and 46.5% interest
as a limited partner in two real estate partnerships and signed agreements to
lease buildings from the limited partnerships.  Both of the above commitments
are included in future operating lease commitments in Note 7.  The investment
in these partnerships of approximately $5.2 million at December 31, 1993 and
1992 is included in other assets in the accompanying balance sheets.  The
Company accounts for these investments under the equity method of accounting.
During June 1991 the Company acquired an 80% interest in a third real estate
partnership which has purchased land for future expansion.  This partnership is
consolidated in the accompanying financial statements.

             REVENUE RECOGNITION

             Product revenue consists principally of revenue earned under
software license agreements.  Revenue earned under license agreements to end
users is generally recognized when a customer purchase order has been received,
the software has been shipped, the Company has a right to invoice the customer
and there are no significant obligations remaining.  Design services revenue
and test equipment revenue are recognized upon delivery of the final design or
shipment of the test equipment.   Nonrefundable revenue earned under guaranteed
revenue commitments from products relicensed through OEMs, system integrators
and software value-added relicensors is recognized at the latter of the
beginning of the commitment period or shipment of the initial product master.
Additional revenue under these agreements is recognized at the time such
amounts are reported to the Company.

             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 1993, 1992 and 1991 one customer (a distributor) accounted for
13%, 14% and 13% of total revenue, respectively.

             SOFTWARE DEVELOPMENT COSTS

             The Company capitalizes internally generated software development
costs in compliance with Statement of Financial Accounting Standards 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 for 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, including, but not limited to, anticipated future
gross product revenue, estimated economic life and changes in software and
hardware technology.  Software development costs capitalized were $15,207,000,
$14,741,000 and $16,188,000 for the years ended December 31, 1993, 1992 and
1991, respectively.

             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 the remaining estimated economic life
of the product (three to five years).  Amortization, which is included in cost
of revenue in the accompanying statements of income, amounted to  $13,065,000,
$11,043,000 and $11,904,000 for the years ended December 31, 1993, 1992 and
1991, respectively. The Company wrote off $1,495,000 of capitalized software in
1993 for projects discontinued during the year.  In connection with the merger
with Valid, the Company also wrote off  $2,794,000 and $10,896,000 of
capitalized software in 1992 and 1991, respectively, due to an overlap of
products.

             PURCHASED SOFTWARE AND INTANGIBLES

             Purchased software and intangibles are stated at cost less
accumulated amortization.  Amortization is generally computed on a
straight-line basis over the remaining estimated economic life of the
underlying product (two to seven years).  The cost and related accumulated
amortization of purchased software and intangibles were as follows (in
thousands):

             INCOME TAXES

             Through December 31, 1992 the Company accounted for income taxes
pursuant to Statement of Financial Accounting Standards ("SFAS") No. 96,
"Accounting for Income Taxes."  Effective January 1, 1993 the Company
retroactively adopted the provisions of SFAS No.109, "Accounting for Income
Taxes."  This statement provides for a liability approach under which deferred
income taxes are provided based upon enacted tax laws and rates applicable to
the periods in which the taxes become payable.  The adoption of this accounting
pronouncement did not have a material impact on the prior years' financial
statements (see Note 11).

             FOREIGN CURRENCY TRANSLATION

             As of December 31, 1991 the functional currency of certain of the
Company's foreign subsidiaries was the U.S. dollar, whereas the functional
currency of the former Valid subsidiaries was the local currency.  During 1992,
the Company made certain changes in the manner in which the subsidiaries'
operations were conducted to conform more closely to the Valid business model.
Accordingly, the functional currency of the U.S. dollar foreign subsidiaries
was changed to the respective local currency effective for the first quarter of
1992.  Gains and losses resulting from the translation of the financial
statements for the subsidiaries are reported as a separate component of
stockholders' equity.

             MERGER COSTS

             Total costs incurred by the Company and Valid in 1991 in
connection with the merger of the two companies were $1,660,000.  These costs,
consisting primarily of legal, accounting and other related expenses, were
charged to operations in the fourth quarter of 1991.

             NET INCOME (LOSS) PER SHARE

             Net income per share for each period is calculated by dividing net
income attributable to common stockholders by the weighted average number of
common stock and common stock equivalents outstanding during the period.
Common stock equivalents consist of dilutive shares issuable upon the exercise
of outstanding common stock options and warrants and the conversion of Series
A-1 preferred stock.  Net loss per share is calculated by dividing net loss
attributable to common stockholders by the weighted average number of common
shares.  Fully diluted net income (loss) per share is substantially the same as
primary net income (loss) per share.

             DISCLOSURE OF NONCASH FINANCING AND INVESTING ACTIVITIES

Notes payable and capital lease obligations incurred for property, plant and
equipment placed into service in 1993, 1992 and 1991 were $4,441,000,
$5,498,000 and $2,195,000, respectively.


             As discussed in Note 1, in June 1993 the Company acquired the
business and certain assets of Comdisco in exchange for 1,050,000 shares of the
Company's common stock and a warrant to purchase 1,300,000 shares of the
Company's common stock.  The cost in excess of net assets acquired was
$6,500,000 which is being amortized over seven years and is included in
purchased software and intangibles in the accompanying balance sheet.  The
accumulated amortization as of December 31, 1993 was approximately $436,000.
In connection with the acquisition, net assets acquired were as follows (in

</TABLE>

             In March 1992 the Company acquired a distributorship in Japan,
which, as its sole operation, had distributed the Company's system products.
As part of this transaction, the Company paid approximately $400,000 in cash
and issued a note for $3,100,000 in exchange for stock and a consulting
agreement.  This acquisition was accounted for as a purchase.  The cost in
excess of the net assets acquired was approximately $5.2 million which is being
amortized over five years and is included in other assets in the accompanying
balance sheets. The accumulated amortization as of December 31, 1993 and 1992
was approximately $2,079,000 and $854,000, respectively.

             During 1992 all of the Company's outstanding Series A-1 preferred
stock was converted to approximately 861,000 shares of the Company's common
stock.

             FAIR VALUE OF FINANCIAL INSTRUMENTS

             The following methods and assumptions were used to estimate the
fair value of each class of financial instruments for which it is practicable
to estimate that value.

             The carrying amount of cash and cash investments and short-term
investments is a reasonable estimate of fair value because of the short
maturity of those instruments.

             The fair value of the Company's long-term obligations, excluding
capital leases, is estimated based on the quoted market prices for the same or
similar issues or on the current rates offered to the Company for debt of the
same remaining maturities.  The carrying amount of the Company's long-term debt
at December 31, 1993 approximates its fair value.





                                       39
<PAGE>   42
             The Company enters into forward exchange contracts to reduce the
impact of foreign currency fluctuations on those accounts that give rise to
transaction gains or losses.  As of December 31, 1993 the Company had entered
into forward exchange contracts in the amount of $33,058,000, maturing January
31, 1994.  The fair value of foreign currency contracts is estimated by
obtaining quotes from banks.  The market value was approximately the same as
the carrying value as of December 31, 1993.

             CONCENTRATION OF CREDIT RISK

             Financial instruments which may potentially subject the Company to
concentrations of credit risk consist principally of cash and cash investments,
short-term investments and accounts receivable.  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.

             RESTRUCTURING COSTS

             In March 1993 the Company recorded restructuring costs of
$13,450,000 associated with a planned restructure of certain areas of sales,
operations and administration due to business conditions.  The restructuring
charge primarily reflects costs associated with excess facilities, the
write-off of software development costs and purchased software and intangibles
and employee terminations resulting from the change in product strategy and
lower revenue levels.

             In December 1991 the Company recorded restructuring costs of
$49,901,000 associated with the merger of Valid with the Company.  This amount
included approximately $5,530,000 for excess fixed assets and other assets,
$13,385,000 for severance and payroll-related payments, $16,475,000 for closing
of excess and duplicate facilities, $10,896,000 for write-offs of capitalized
software due to overlap of products and $3,615,000 for other items.

             POST RETIREMENT BENEFITS

             Statement of Financial Accounting Standards No. 106, "Accounting
for Post Retirement Benefits other than Pensions," which was effective for the
Company in fiscal 1993, has no effect on the Company as the Company has not
offered such post retirement benefits.

             INVESTMENTS IN DEBT AND EQUITY SECURITIES

             Statement of Financial Accounting Standards No. 115, "Accounting
for Certain Investments in Debt and Equity Securities," which will be effective
for the Company in fiscal 1994, is not expected to have a material impact on
the Company.

7.    LEASES

             Facilities and equipment are leased under various capital and
operating leases expiring on different dates through the year 2008.  Certain of
these leases contain renewal options.  The terms of several of the facilities
agreements, accounted for as operating leases, provide for the deferral of
several months' rental payments or scheduled rent increases.  Rental expense
under these agreements is recognized on a straight-line basis.  Rental expense
was approximately $19,983,000, $21,287,000 and $16,798,000 for the years ended
December 31, 1993, 1992 and 1991, respectively.

             In connection with the merger with Valid and planned restructure,
the Company has closed certain excess and duplicate facilities.  Accordingly,
the Company has accrued for estimated future minimum rent and maintenance costs
related to these facilities.  Total costs accrued at December 31, 1993 were
$8,557,000, of which $1,193,000 is included in accrued liabilities and
$7,364,000 is included in lease liabilities in the accompanying balance sheet.

             In connection with the disposition of ASI, the Company has accrued
for estimated future rent on facilities not assumed by the purchaser.  Total
costs accrued at December 31, 1993 were $1,911,000, of which $102,000 is
included in accrued liabilities and $1,809,000 is included in other noncurrent
liabilities in the accompanying balance sheet.

             As of December 31, 1993 the Company had $15.0 million available
for future borrowings under capital lease agreements which expire in September
1994.

8.    LINES OF CREDIT

             The Company has unsecured lines of credit with two banks allowing
for combined maximum borrowings of $17,500,000 in the form of (a) domestic rate
revolving loans with interest at the banks' prime lending rate, (b) Eurodollar
rate loans with interest that exceeds  three- quarters of one percent of the
banks' current Eurodollar rate quoted for the same amount and maturity, or (c)
issuances of letters of credit.  There were no outstanding borrowings at
December 31, 1993 or 1992 under these agreements.  Certain financial covenants
and restrictions are included in these agreements.  As a result of its treasury
stock purchase activity during 1993, the Company was not in compliance with
certain covenants related to one of its lines of credit, with a borrowing
amount of $10,000,000, as of December 31, 1993.  The Company subsequently
obtained a waiver of the noncompliance from the bank.   These lines of credit
will expire in May 1994 and June 1994.

9.    COMMITMENTS AND CONTINGENCIES

             The Company has entered into an executive compensation agreement
with one of its executive officers.  This agreement provides severance benefits
to the executive in the event that within 120 days before or two years after
any change in control, or sale of all or substantially all assets of the
Company, the executive's employment is terminated by the Company or the
executive, in circumstances described in the agreement.  The severance benefits
are a cash payment of two times the executive's base salary, plus accelerated
vesting of all outstanding stock options.

             The Company assumed as part of the ASI acquisition an agreement
dated April 22, 1985 under which the Company is obligated to pay to a former
ASI officer a monthly annuity for a fifteen-year period after his retirement
date or a lump sum payment subject to the terms of the agreement.  The Company
has accrued an amount equal to the present value of the estimated future
payments at the eligible retirement date.  Such accrual amount is included in
accrued liabilities in the accompanying balance sheet.

             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 and the stockholder class action lawsuits described below,
which allege violation of certain federal securities laws by maintaining
artificially high market prices for the Company's common stock through alleged
misrepresentations and nondisclosures regarding the Company's financial
condition.

             Stockholder class action lawsuits were filed against the Company
and certain of its officers and directors in the United States District Court
for the Northern District of California, San Jose Division, on April 8 and 9,
1991.  The suits were subsequently consolidated into a single lawsuit and the
class period changed to include purchasers of the Company's common stock during
the period from October 18, 1990 through April 3, 1991.  The plaintiff in the
suit seeks compensatory damages unspecified in amount.  On June 2, 1993 the
District Court granted in part and denied in part the Company's motion to
dismiss the Complaint in the class action originally filed in April 1991.  The
effect of the ruling was to limit the class period to include purchasers of the
Company's common stock between January 29, 1991 and April 3, 1991.  Trial of
this matter is scheduled to commence on August 8, 1994.  The Company is
vigorously defending against the litigation.

             On March 23, 1993 a separate class action lawsuit was filed
against the Company and certain of its directors and officers in the United
States District Court, Northern District of California,  San Jose Division. Two
additional complaints, identical to the complaint filed on March 23, 1993
except for the identities of the plaintiffs, were filed later in March and in
April 1993. All three complaints were consolidated into a single lawsuit which
seeks unspecified damages on behalf of all purchasers of the Company's common
stock between October 12, 1992 and March 19, 1993.  On November 18, 1993, the
District Court granted the Company's motion to dismiss the 1993 complaint.  The
effect of the ruling was to dismiss the complaint except as to a statement
allegedly made on January 28, 1993, but plaintiffs were granted leave to
further amend their complaint.  The Company is vigorously defending against the
litigation.

             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.

10.   STOCKHOLDERS' EQUITY

             REDEEMABLE CONVERTIBLE PREFERRED STOCK

             The Company has 2,000,000 shares of authorized and unissued
preferred stock at $.01 par value per share.  At December 31, 1993 and 1992
there were no shares of preferred stock outstanding.

             In 1990 a corporation  acquired a minority interest in Valid
through an initial investment of $10,998,000, in exchange for 86,133 shares of
newly issued Series A-1 voting, convertible preferred stock, convertible into
861,330 common shares, at a purchase price equivalent to $13.00 per common
share.  All of the preferred stock was converted to common stock during 1992.
In 1990 the corporation also purchased, for $1,187,500, a warrant to acquire up
to 4,750,000 shares of Valid's common stock.  This warrant was exchanged for
approximately 199,000 shares of common stock upon the merger of Valid with the
Company.

             Each share of Series A-1 preferred stock was entitled to receive
cumulative annual dividends.  The dividends were payable in cash.  In 1992 and
1991 the Company recorded $559,000 and $1,344,000, respectively, for dividends
paid to the corporation.

             EMPLOYEE STOCK OPTION PLANS

             The Company's Employee Stock Option Plan (the "Plan") provides for
employees to be granted options to purchase up to 13,637,800 shares of common
stock.   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.  At December 31, 1993 options to purchase 8,320,101 shares were
outstanding under the Plan, of which options for 1,317,646 shares were
exercisable at prices ranging from $2.00 to $28.75.  Options to purchase
1,284,864 shares were available for future grant under the Plan.  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
$8.81 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 4,856,026 shares were exchanged.  Options to
purchase 4,032,835 shares of common stock  have been exercised as of December
31, 1993.

             During 1993 the Company adopted a Non-Statutory Stock Option Plan
(the "Non-Statutory Plan").  The Company has reserved 2,500,000 shares of
common stock for issuance under the 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.
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 Non-Statutory options generally expire ten years from the
date of grant. At December 31, 1993 options to purchase 1,230,225 shares were
outstanding, none of which were exercisable.  Options to purchase 1,269,775
shares were available for future grant under the Non-Statutory Plan.

             The Company has reserved a total of 1,313,996 shares of its
authorized common stock for issuance upon the exercise of options granted to
former employees of companies acquired (the "Acquired Options").   The Acquired
Options were assumed by the Company outside 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.  At December 31, 1993
Acquired Options to purchase a total of 1,313,996 shares were outstanding, of
which 1,128,756 were exercisable at prices ranging from $.41 to $21.52.  No
additional options will be granted under any of the acquired companies' plans.

             STOCKHOLDER RIGHTS PLAN

             During 1989 the Company adopted a Stockholder Rights Plan.  As
part of this plan the Company's Board of Directors declared a dividend of one
Common Share Purchase Right (the "Right") for each share of the Company's
common stock outstanding on July 20, 1989.  The Board also authorized the
issuance of one such Right for each share of the Company's common stock issued
after July 20, 1989 until the occurrence of certain events.

             Each Right entitles the holder thereof to purchase one share of
the Company's common stock for $100, subject to adjustment in certain events.
The Rights are not exercisable until the occurrence of certain events related
to a person acquiring, or announcing the intention to acquire, 20% or more of
the Company's common stock.  Upon such acquisition, each Right (other than
those held by the acquiring person) will be exercisable for that number of
shares of the Company's common stock having a market value of two times the
exercise price of the Right.  If the Company subsequently enters into certain
business combinations, each Right (other than those held by the acquiring
person) will be exercisable for that number of shares of common stock of the
other party to the business combination having a market value of two times the
exercise price of the Right.  The Rights currently trade with the Company's
common stock.  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, and are exchangeable for the Company's common stock, at the discretion
of the Board of Directors, under certain circumstances.  The Rights expire on
May 30, 1999.

                          CADENCE DESIGN SYSTEMS, INC.

                             A DELAWARE CORPORATION

                        1993 DIRECTORS STOCK OPTION PLAN

                            AS ADOPTED JULY 22, 1993



         1.      PURPOSE.  This Stock Option Plan ("Plan") is established to
provide equity incentives for members of the Board of Directors of Cadence
Design Systems, Inc., a Delaware corporation (the "Company") who are not
employees of the Company, by granting such persons options to purchase shares
of stock of the Company.

         2.      ADOPTION AND STOCKHOLDER APPROVAL.  This Plan shall become
effective on the date that it is adopted by the Board of Directors (the
"Board") of the Company.  This Plan shall be approved by the stockholders of
the Company within twelve months before or after the date this Plan is adopted
by the Board.

         3.      TYPES OF OPTIONS AND SHARES.  Options granted under this Plan
(the "Options") shall be nonqualified stock options  ("NQSOs").  The shares of
stock that may be purchased upon exercise of Options granted under this Plan
(the "Shares") are shares of the common stock of the Company.

         4.      NUMBER OF SHARES.  The maximum number of Shares that may be
issued pursuant to Options granted under this Plan is 107,223 Shares*, subject
to adjustment as provided in this Plan.  If any Option is terminated for any
reason without being exercised in whole or in part, the Shares thereby released
from such Option shall be available for purchase under other Options
subsequently granted under this Plan.  At all times during the term of this
Plan, the Company shall reserve and keep available such number of Shares as
shall be required to satisfy the requirements of outstanding Options under this
Plan.

         5.      ADMINISTRATION.  This Plan shall be administered by the Board
or by a committee of not less than two members of the Board appointed to
administer this Plan (the "Committee").  As used in this Plan, references to
the Committee shall mean either such Committee or the Board if no committee has
been established.  The interpretation by the Committee of any of the provisions
of this Plan or any Option granted under this Plan shall be final and binding
upon the Company and all persons having an interest in any Option or any Shares
purchased pursuant to an Option.

*Does not include 337,777 Options granted under the predecessor plan (the 1988
Directors Stock Option Plan).





                                       59
<PAGE>   2
         6.      ELIGIBILITY.  The Directors Plan provides that options may be
granted only to such directors of the Company (collectively, "Optionees" and
individually "Optionee") as the Committee shall select from time to time;
provided, however, that no director of the Company who is also an employee of
the Company or of any parent or subsidiary of the Company may be granted an
Option.  Optionees may be granted more than one Option; provided, however, that
the aggregate number of shares subject to all Options granted to an Optionee
will be as follows: (i) 100,000 shares, in the case of Options granted to the
Chairman of the Board, (ii) 75,000 shares, in the case of Options granted to
the Chairman of the Compensation Committee of the Board, and (iii) 50,000
shares, in the case of Options granted to any other director.  Options will be
granted on the date or dates specified in Section 7(d) below. The provisions of
this Section 6 shall not be amended more than once every six months, other than
to comply with changes in the Internal Revenue Code of 1986, as amended or the
rules thereunder.

         7.      TERMS AND CONDITIONS OF OPTIONS.  The Committee shall
determine all terms and conditions of the Option, subject to the following
terms and conditions:

                 (a)      Form of Option Grant.  Each Option granted under this
Plan shall be evidenced by a written Stock Option Grant ("Grant") in such form
(which need not be the same for each Optionee) as the Committee shall from time
to time approve, which Grant shall comply with and be subject to the terms and
conditions of this Plan.

                 (b)      Exercise Price.  The exercise price of an Option
shall be the fair market value of the Shares, at the time that the Option is
granted, as determined by the Committee in good faith; provided, however, that
where there is a public market for the Company's Common Stock, the fair market
value per Share shall be the average of the high and low closing sales price of
the Company's Common Stock on the date of grant, as quoted on the New York
Stock Exchange.

                 (c)      Exercise Period.  Options shall be exercisable as to
1/3rd of the Shares on the first anniversary of the Grant Date and as to an
additional 1/36th of the Shares for each full month thereafter, and remain
exercisable for a period of ten years; provided, however, that no Option shall
be exercisable after the expiration of ten years from the date of grant, and
provided further that notwithstanding anything to the contrary, with respect to
the initial grant of an Option, if an Optionee ceases to serve as Chairman of
the Board or as Chairman of the Compensation Committee of the Board but
continues to serve as a member of the Board, then Options to purchase in excess
of an aggregate of 50,000 shares ("Extra Options") held by such Optionee shall
terminate and may not be exercised, except within the time periods and to the
extent described in the Grant, with the date of such cessation deemed the
Termination Date, and the fact of such cessation deemed the cessation or
termination of service as a Director, within the meaning of those Sections with
respect only to such Extra Options.

                 (d)      Date of Grant.  The initial Option grant to a
director shall be for 20,000 shares and such Option will be deemed granted on
the date of appointment to the position of director.  Subsequent grants in
increments of 15,000 shares up to the maximum of 50,000 shares shall be
immediately after the date on which his or her outstanding options become fully
exercisable.  The date of grant of an Extra Option for the Chairman of the
Board and Chairman of the Compensation Committee shall be immediately upon
election to such position, whichever is later, or upon stockholder approval of
an amendment to the Plan, authorizing such Extra Option. The Grant representing
the Option shall be delivered to the Optionee within a reasonable time after
the granting of the Option.

         8.      EXERCISE OF OPTIONS.

                 (a)      Notice.  Options may be exercised only by delivery to
the Company of written notice and exercise agreement in a form approved by the
Committee, stating the number of Shares being purchased, the restrictions
imposed on the Shares and such representations and agreements regarding the
Optionee's investment intent and access to information as may be required by
the Company to comply with applicable securities laws, together with payment in
full of the exercise price for the number of Shares being purchased.

                 (b)      Payment.  Payment for the Shares may be made (i) in
cash (by check), (ii) by surrender of shares of common stock of the Company
having a fair market value equal to the exercise price of the Option: (iii)
where permitted by applicable law, by tender of a full recourse promissory note
having such terms as may be approved by the Committee; or (iv) by any
combination of the foregoing.

                 (c)      Withholding Taxes.  Prior to issuance of the Shares
upon exercise of an Option, the Optionee shall pay or make adequate provision
for federal or state withholding obligations of the Company, if applicable.

                 (d)      Limitations on Exercise.  Notwithstanding the
exercise periods set forth in the Grant, exercise of an Option shall always by
subject to the following limitations:

                          (i)     An Option shall not be exercisable unless
such exercise is in compliance with the Securities Act of 1933, as amended, and
all applicable state securities laws, as they are in effect on the date of
exercise.

 (ii)    An Option shall not be exercisable until this Plan has been approved by
                                                the stockholders of the Company.

                          (iii)   The Committee may specify a reasonable
minimum number of Shares that may be purchased on any exercise of an Option,
provided that such minimum number will not prevent the Optionee from exercising
the full number of Shares as to which the Option is then exercisable.

         9.      NONTRANSFERABILITY OF OPTIONS.  During the lifetime of the
Optionee, an Option shall be exercisable only by the Optionee.  No Option may
be sold, pledged, assigned, hypothecated, transferred or disposed of in any
manner other than by will or by the laws of descent and distribution.

         10.     PRIVILEGES OF STOCK OWNERSHIP.  No Optionee shall have any of
the rights of a stockholder with respect to any Shares subject to an Option
until the Option has been validly exercised.  No adjustment shall be made for
dividends or distributions or other rights for which the record date is prior
to the date of exercise, except as provided in this Plan.  The Company shall
provide to each Optionee a copy of the annual financial statements of the
Company, at such time after the close of each fiscal year of the Company as
they are released by the Company to its stockholders.

         11.     ADJUSTMENT OF OPTION SHARES.  In the event that the number of
outstanding shares of common stock of the Company is changed by a stock
dividend, stock split, reverse stock split, combination, reclassification or
similar change in the capital structure of the Company without consideration,
the number of Shares available under this Plan and the number of Shares subject
to outstanding Options and the exercise price per





                                       61
<PAGE>   4
share of such Options shall be proportionately adjusted, subject to any
required action by the Board or stockholders of the Company and compliance with
applicable securities laws; provided, however, that no certificate or scrip
representing fractional shares shall be issued upon exercise of any Option and
any resulting fractions of a Share shall be ignored.

         12.     NO OBLIGATION TO RETAIN.  Nothing in this Plan or any Option
granted under this Plan shall confer to any Optionee any right to continue as a
Director of the Company.

         13.     COMPLIANCE WITH LAWS.  The grant of Options and the issuance
of Shares upon exercise of any Options shall be subject to and conditioned upon
compliance with all applicable requirements of law, including without
limitation compliance with the Securities Act of 1933, as amended, any required
approval by the Commissioner of Corporations of the State of California,
compliance with all other applicable state securities laws and compliance with
the requirements of any stock exchange on which the Shares may be listed.  The
Company shall be under no obligation to register the Shares with the Securities
and Exchange Commission or to effect compliance with the registration or
qualification requirement of any state securities laws or stock exchange.

         14.     ACCELERATION OF OPTIONS ON ACQUISITION.  In the event of a
dissolution or liquidation of the Company, a merger in which the Company is not
the surviving corporation, or the sale of substantially all of the assets of
the Company, any or all outstanding Options shall, notwithstanding any contrary
terms of the Grant, accelerate and become exercisable in full prior to the
consummation of such dissolution, liquidation, merger or sale of assets.

         15.     AMENDMENT OR TERMINATION OF PLAN.  Subject to the limitations
set forth in Section 6 above, the Committee may at any time terminate or amend
this Plan in any respect (including, but not limited to, any form of Grant,
agreement or instrument to be executed pursuant to this Plan); provided,
however, that the Committee shall not, without the approval of the stockholders
of the Company, increase the total number of Shares available under this Plan
(except by operation of the provisions of this Plan) or change the class of
persons eligible to receive Options.  In any case, no amendment of this Plan
may adversely affect any then outstanding Options or any unexercised portions
thereof without the written consent of the Optionee.

         16.     TERM OF PLAN.  Options may be granted pursuant to this Plan
from time to time within a period of ten years from the date this Plan is
adopted by the Board of Directors.

         1.      GRANT OF OPTION.  Cadence Design Systems, Inc., a Delaware
corporation (the "Company"), hereby grants to the optionee named above
("Optionee") an option (this "Option") to purchase the total number of shares
of common stock of the Company set forth above (the "Shares") at the exercise
price per share set forth above (the "Exercise Price:), subject to all of the
terms and conditions of  this Grant and the Company's 1988 Directors Stock
Option Plan as adopted July 22, 1993 (the "Plan").

         2.      EXERCISE PERIOD OF OPTION.  Subject to the terms and
conditions of the Plan and this Grant, this Option shall become exercisable as
to portions of the Shares as follows:  this Option shall vest over a three-year
period, becoming exercisable as to 1/3rd of the Shares on the first anniversary
of the Grant Date and as to an additional 1/36th of the Shares for each full
month thereafter, with the number of Shares as to which this Option may be
exercised at a given time being rounded to the nearest whole number, not to

expire on the Expiration Date set forth above and must be exercised, if at all,
on or before the Expiration Date.

         3.      RESTRICTIONS ON EXERCISE.  Exercise of this Option is subject
                 to the following limitations:

                 (a)      This Option may not be exercised unless such exercise
is in compliance with the Securities Act of 1933, as amended, and all
applicable state securities laws, as they are in effect on the date of
exercise.

                 (b)      This Option may not be exercised as to fewer than 100
Shares unless it is exercised as to all Shares as to which this Option is then
exercisable.

<PAGE>   6
         4.      TERMINATION OF OPTION.  Except as provided below in this
Section, this Option shall terminate and may not be exercised if Optionee
ceases to serve as a Director of the Company.  The Board of Directors of the
Company shall have discretion to determine whether Optionee has ceased to serve
as a Director of the Company and the effective date on which such service
terminated (the "Termination Date").

                 (a)      If Optionee ceases to serve as a Director of the
Company for any reason except death or disability, this Option, to the extent
(and only to the extent) that it would have been exercisable by Optionee on the
Termination Date, may be exercised by Optionee within seven months after the
Termination Date, but in any event no later than the Expiration Date.

                 (b)      If Optionee's service as a Director of the Company is
terminated because of the death of Optionee or disability of Optionee within
the meaning of Section 22(e)(3) of the Internal Revenue Code of 1986, this
Option, to the extent that it is exercisable by Optionee on the Termination
Date, may be exercised by Optionee (or Optionee's legal representative) within
twelve months after the Termination Date but in any event no later than the
Expiration Date.

                 Nothing in the Plan or this Grant shall confer on Optionee any
right to continue to serve as a Director of the Company.

         5.      MANNER OF EXERCISE. 

                 (a) This Option shall be exercisable by delivery to the
Company of an executed written Notice and Agreement in the form attached hereto
as Exhibit A, or in such other form as may be approved by the Company, which
shall set forth Optionee's election to exercise this Option, the number of
Shares being purchased, any restrictions imposed on the Shares and such other
representations and agreements regarding Optionee's investment intent and
access to information as may be required by the Company to comply with
applicable securities laws.

                 (b)  Such notice shall be accompanied by full payment of the
exercise Price for the Shares being purchased (i) in cash (by check); (ii) by
surrender of Shares of Common Stock of the Company having a fair market value
equal to the Exercise Price; (iii) where permitted by applicable law, by tender
of a full recourse promissory note having such terms as the Board of Directors
or the committee thereof that administers the Plan may approve; or (iv) by any
combination thereof.

         (c)  Prior to the issuance of the Shares upon exercise of this Option,
Optionee must pay or make adequate provision for any applicable federal or
state withholding obligations of the Company.

         (d)  Provided that such notice and payment are in form and substance
satisfactory to counsel for the Company, the Company shall issue the Shares
registered in the name of Optionee or Optionee's legal representative.

         6.      COMPLIANCE WITH LAWS AND REGULATIONS.   The issuance and
transfer of Shares shall be subject to compliance by the Company and the
Optionee with all applicable requirements of federal and state securities laws
and with all applicable requirements of any stock exchange on which the
Company's Common Stock may be listed at the time of such issuance or transfer.
Optionee understands that the Company is under no obligation to register or
qualify the Shares with the Securities and Exchange





                                       64
<PAGE>   7
Commission, any state securities commission or any stock exchange to effect
such compliance.

         7.      NON TRANSFERABILITY OF OPTION.  This Option may not be
transferred in any manner other than by will or by the laws of descent and
distribution and may be exercised during the lifetime of the Optionee only by
the Optionee.  The terms of this Option shall be binding upon the executors,
administrators, successors and assigns of the Optionee.

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

                 There may be a regular federal income tax liability and a
California income tax liability upon the exercise of the Option.  The Optionee
will be treated as having received compensation income (taxable at ordinary
income tax rates) equal to the excess, of any, of the fair market value of the
Shares on the date of exercise over the Exercise Price.  The Company may be
required to withhold from Optionee's compensation or collect from Optionee and
pay to the applicable taxing authorities an amount equal to a percentage of
this compensation income at the time of exercise.  Any gain on sale of the
Shares will be taxed as capital gain.

         9.      INTERPRETATION.  Any dispute regarding the interpretation of
this Grant shall be submitted by Optionee or the Company forthwith to the
Company's Board of Directors or the committee thereof that administers the

                          CADENCE DESIGN SYSTEMS, INC.
                          SENIOR EXECUTIVE BONUS PLAN
                      JANUARY 1, 1994 - DECEMBER 31, 1994


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, 1995.
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.  The Bonus Pool
will be generated as a percentage of the target Bonus Pool as follows:

<TABLE>
<CAPTION>
                     EPS              Bonus Pool Percentage
                     ---              ---------------------
                    <S>                         <C>
                    $0.84                        75%
                    $0.92                       100%
                    $1.00                       125%
                    $1.20                       150%
</TABLE>

If Earnings Per Share fall below $0.84 or exceed $1.20, 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 1994 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 1994, 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 as of December 31, 1994.  All forfeitures revert
to Cadence.

                           KEY CONTRIBUTOR BONUS PLAN
                        JANUARY 1, 1994 - JUNE 30, 1994

The purpose of the Key Contributor Bonus Plan is to motivate and reward key
employees to profitably grow Cadence and achieve individual pre- determined
goals.  The plan provides for a cash payment payable by September 1, 1994.

The participants will normally be Direct Reports to Officers (excluding Sales),
Directors and Managers as well as other selected key individual contributors.
The  participants will be selected on a semi-annual basis for the appropriate
one half year participation in the Plan.

The Bonus Pool will be determined as follows:

    o    Performance Gate:  The Bonus Pool will be determined based on
         Cadence's performance against Earnings Per Share (EPS) targets.  The
         Bonus Pool will be generated as a percentage of the target Bonus Pool
         as follows:

<TABLE>
<CAPTION>
                     EPS              Bonus Pool Percentage
                     ---              ---------------------
                    <S>                         <C>
                    $0.24                        75%
                    $0.26                       100%
                    $0.28                       125%
                    $0.33                       150%
</TABLE>

         If Earnings Per Share fall below $0.24 or exceed $0.33 the Bonus Pool
         will be determined at the sole discretion of the Board of Directors.

    o    Bonus Fund:  Plan participants will be targeted for 10%, 15% or 25% of
         base salary during the plan period.  The target level is determined by
         the position held.  The target bonus fund will be made up of the sum
         of the target bonuses.

    o    Management Judgment Bonus Fund:  In addition to the target pool
         described above, a fund equivalent to 5% of base salary paid to
         participants during the plan period will be established. The fund will
         be adjusted up or down based on the EPS performance targets described
         above.  This will be used to further reward individuals or work teams
         based on such factors as difficulty and value of objectives achieved,
         overall performance level on a sustained basis, contribution to the
         success of Cadence over time, or any other considerations determined
         applicable by the management of Cadence.

Individual bonus awards are based on performance against specific objectives
for the plan period.  The award can be varied from 50% to 150% of target as
follows:

         Minimum individual performance rating to receive a bonus is .50 and
below .50 no bonus is to be paid.  Maximum rating is 1.50.
<TABLE>
                   <S>                                                  <C>
                   Rating scale is:
                   Performance Significantly Exceeds Objectives         - 1.26 to 1.50
                   Performance Exceeds Objectives                       - up to 1.25
                   Performance Meets Objectives                         - 1.00
                   Performance Meets Most Objectives                    - .75 to .99
                   Performance Meets Some Objectives                    - .50 to .74
                   Performance Does Not Meet Objectives                 - under .50 (No Bonus)
</TABLE>

The total of the individual bonuses will be controlled to the Bonus Pool as
adjusted by the plan performance factors described above.

In order to receive a bonus, the individual must be an active employee as of
June 30, 1994.  The bonus pool will be reduced or increased for any additions
or deletions during the year.  No additions will be made for less than one
quarter year participation.  All forfeitures revert to Cadence.

In the event of a death or disability, a pro-rata bonus (of target) will be
paid to the employee or his/her estate if there is a Bonus Pool per this Plan.

Cadence reserves the right to modify or cancel the Key Contributor Bonus Plan
at any time.  This Plan is only effective for the period - January 1, 1994 to
June 30, 1994.  Any future plan is at the discretion of Cadence.

Participation in the Plan does not constitute an agreement to employ the
participant for any length of time and shall not restrict the Company's right
to terminate the employment of the participant for any reason and at any time.

     annuity form of benefit pursuant to this subparagraph, his distribution

     benefits provided by the Plan shall be distributed as follows:
 
          (a) (1) Married Participants.  The benefits under the Plan for a
     Participant who has been married for at least one (1) year on the date the
     benefit payments commence, shall be in the form of a qualified joint and
     survivor annuity, payable in equal monthly installments, commencing on the
     Participant's Normal Retirement Date, or such earlier date as the
     Participant may elect which is after such Participants' termination of

     life of the spouse which is fifty percent (50%) of the amount of the
     annuity payable during the joint lives of the Participant and the
     Participant's spouse. This qualified joint and survivor annuity shall be
     the Actuarial Equivalent of the value of the Participant's vested Accounts
     determined as of the Valuation Date coinciding with or next following the
     Participant's termination of employment. For purposes of this Article 12.6,

     mathematically equivalent to another amount based on consistently applied
     reasonable actuarial assumptions selected by the
 
                                       70
<PAGE>   4
 
     Employer, if such assumptions do not result in discrimination in favor of
Employees who are Highly Compensated Employees.
 
          (2) Unmarried Participants.  If a Participant has not been married for
     at least one year on the date benefit payments commence, and does not have
     a former spouse or spouses who is/are entitled to survivor annuity benefits
     under a qualified domestic relations order as provided in Article 22.4 the
     benefits under the Plan for such Participant shall be in the form of a life
     annuity, payable in equal monthly installments, commencing on the
     Participants' Normal Retirement Date, or such earlier date after
     termination of employment as the Participant may elect, for the life of the
     Participant. This life annuity shall be the Actuarial Equivalent of the
     value of the Participants' vested Accounts determined as of the Valuation
     Date coinciding with or next following the Participants' termination of
     employment.
 
          Any Participant who has elected an annuity form of benefit, may at any
     time prior to the annuity starting date, revoke such election and elect to
     have benefits paid in one of the options set forth in Article 12.1(a),
     subject, however, to the provisions of Article 12.6(c).
 
          (b) Death Benefits.  Upon the death of a Participant who has elected
     an annuity form of benefit pursuant to Article 12.1(a)(1), his or her
     Beneficiary shall be entitled to receive a death benefit determined as
     follows:
 
          (1) The death benefits, if any, payable upon the death of any
     Participant who is receiving (or has received) retirement benefits under
     the Plan will depend upon whether the particular form of annuity which such
     Participant is receiving (e.g., life annuity or joint and survivor annuity)
     provides for any survivor or other death benefits and shall be paid in
     accordance with the form of benefit which such Participant had been
     receiving.
 
          (2) If a Participant who has not begun to receive payments under the
     Plan either dies while in active service of the Employer, or separates from
     service with vested benefits and thereafter dies before the annuity
     starting date, the surviving spouse, if any, and the Beneficiary of the
     Participant shall be entitled to a death benefit determined as follows:
 
                                       71
<PAGE>   5
 
          (A) If the Participant has been married for at least one (1) year at
     the time of his death, the Participant's surviving spouse shall be entitled
     to a qualified preretirement survivor annuity for the life of such
     surviving spouse which annuity shall be the Actuarial Equivalent of the
     amount equal to the value of fifty percent (50%) of the deceased
     Participant's vested Accounts as of the date of such Participant's death.
     Notwithstanding the foregoing however, the surviving spouse of a deceased
     Participant may elect, in lieu of receiving the qualified preretirement
     survivor annuity, to have fifty percent (50%) of the Participant's vested
     Accounts paid in one of the options as set forth in Article 12.1(a). Any
     such election shall comply with the requirements of Article 12.6(c).
 
          (B) A death benefit will be paid to the Participant's Beneficiary in
     an amount equal to the Participant's vested benefits at the time of the
     Participant's death reduced by any amount payable to a surviving spouse
     pursuant to Article 12.6(b)(2)(A), above. The Beneficiary may elect, with
     respect to any death benefit paid pursuant to this provision, that the
     benefit be paid in one of the options as set forth in Article 12.1(a).
 
          (c) Revocation of Election.  A Participant who has elected an annuity
     form of benefit and the spouse or former spouse of a deceased Participant
     who is entitled to a qualified preretirement survivor annuity, may elect to
     have benefits paid in one of the options set forth in Article 12.1(a),
     subject to the provisions of this Article 12.6(c).
 
          (1) The election to waive the qualified joint and survivor annuity
     must be made within the 90-day period ending on the annuity starting date.
 
          (2) The election by the Participant to waive the qualified
     preretirement survivor annuity may be made or revoked at any time after the
     first day of the Plan Year in which the Participant attains age 35 years,
     but it shall become irrevocable on the Participant's death.
 
          (3) The election by the Participant's spouse to waive the qualified
     preretirement survivor annuity may be made any time prior to the annuity
     starting date.
 
                                       72
<PAGE>   6
 
          (4) Any waiver of a qualified joint and survivor annuity or a
     qualified preretirement survivor annuity shall not be effective unless: (i)
     the Participant's spouse consents in writing to the waiver; (ii) the
     election designates a specific beneficiary, including any class of
     beneficiaries or any contingent beneficiaries, which may not be changed
     without spousal consent (or the spouse expressly permits designations by
     the Participant without any further spousal consent); (iii) the spouse's
     consent acknowledges the effect of the election; and (iv) the spouse's
     consent is witnessed by a representative of the Plan or a notary public.
     Additionally, a Participant's waiver of a qualified joint and survivor
     annuity shall not be effective unless the election designates a form of
     benefit which may not be changed without spousal consent (or the spouse
     expressly permits designations by the Participant without any further
     spousal consent). The spousal consent requirement may be waived by the
     Committee if there is no spouse or the spouse cannot be located, or for
     such other reasons authorized in applicable Treasury Regulations.
 
          (5) Any consent by a spouse obtained under Article 12.6(c)(4) (or
     establishment that the consent of a spouse may not be obtained) shall be
     effective only with respect to such spouse. A consent that permits
     designations by the Participant without any requirement of further consent
     by such spouse must acknowledge that the spouse has the right to limit
     consent to a specific beneficiary, and a specific form of benefit where
     applicable, and that the spouse voluntarily elects to relinquish either or
     both of such rights.
 
          (6) The Committee shall furnish each Participant with an explanation
     of the Plan's qualified joint and survivor annuity provisions, the
     Participant's rights to waive such qualified joint and survivor annuity,
     the effect of such waiver, a general description of the eligibility
     conditions and other material features of the optional forms of benefit and
     sufficient additional information to explain the relative values of the
     optional forms of benefit available under the Plan, the right of a
     Participant's spouse to consent to such waiver, and the right to make, and
     the effect of a revocation of waiver. This explanation shall be furnished
     no less than 30 days and no more than 90 days prior to the annuity starting
     date and in the manner required under applicable Treasury Regulations.
 
                                       73
<PAGE>   7
 
          (7) The Committee shall furnish each Participant with an explanation
     of the qualified preretirement survivor annuity, the Participant's right to
     waive such qualified preretirement survivor annuity, the requirement that
     the Participant's spouse consent to any such waiver, and the right to make,
     and the effect of, a revocation of such waiver. This explanation shall be
     furnished to the Participant within the applicable period with respect to a
     Participant, whichever of the following periods ends last: (i) the period
     beginning on the first day of the Plan Year in which the Participant
     attains age 32 years and ending on the last day of the Plan Year preceding
     the Plan Year in which the Participant attains age 35 years, (ii) a
     reasonable period after the individual becomes a Participant, (iii) a
     reasonable period ending after the qualified preretirement survivor annuity
     is no longer fully subsidized, (iv) a reasonable period ending after
     section 401(a)(11) of the Code first applies to the Participant, and (v) a
     reasonable period after separation from service in case of a Participant
     who separates before attaining age 35. For purposes of applying (ii), (iii)
     and (iv), a reasonable period is the one-year period ending after the date
     the applicable event occurs and the applicable period of such events begins
     one year prior to the occurrence of the enumerated events. For purposes of
     applying (v), the applicable period means the period beginning one year
     before the separation from service and ending one year after such
     separation.
 
          (d) Provision of Annuity Benefits Through Commercial Annuity.  The
     Plan may provide the annuity and qualified preretirement survivor annuity
     benefits provided under this Article 12.6 through the purchase of an
     annuity contract which provides such benefits and which is owned by the

     amounts received for personal services actually rendered in the course of
     employment with the Employer (up to $200,000, multiplied by the Adjustment
     Factor for Plan Years beginning after 1989) which are paid in cash or in
     kind to an Employee during such Plan Year or, for Plan Years beginning

     officer is described
 
                                       78
<PAGE>   12
 
     in subparagraph (1)(D), the highest paid officer of the Employer for such
Plan Year shall be treated as described in subparagraph (1)(D).
 
          (4) For purposes of this Article 1.1(s), a former Employee shall be

     agreement and which is not includable in the Employee's gross income under
     section 125, 402(a)(8), 402(h)(1)(B) or 403(b) of the Code.

     "calendar year calculation election" set forth in the regulations
     promulgated under the Internal Revenue Code.
 
          (10) Notwithstanding any other provision in the Plan, the
     determination of Highly Compensated Employees shall be made in accordance

     3.  A new Article 3.3(d) shall be added as follows:
 
          "(d) The Excess Deferrals which would otherwise be distributed to a
     Participant pursuant to this Article 3.3 shall be reduced by the amount of
     Excess Contributions previously distributed to such Participant for the
     Plan Year, in accordance with regulations promulgated by the Secretary of
     the Treasury."
 
     4.  Article 3.7(c)(2) shall be deleted in its entirety and the following
inserted in lieu thereof:
 
          (2) For purposes of determining the Deferral Percentage of a
     Participant who is a Highly Compensated Employee and is either a 5% owner
     as defined in Article 21.5(3)(a) or one of the ten most Highly Compensated
     Employees of the Employer, the 401(k) Contributions and compensation of
     such Participant shall include the 401(k) Contributions and compensation of
     Family Members, and such Family Members shall be disregarded in determining
     the Deferral Percentages for Participants who are Non-Highly Compensated
     Employees."
 
     5.  A new Article 3.7(c)(6) shall be added as follows:
 
          "(6) 401(k) Contributions shall relate to a Participant's compensation
     that either would have been received by the Participant during the Plan
     Year but for the Participant's election to make 401(k) Contributions or is
     attributable to services performed by the Participant during the Plan Year
     and, but for the Participant's election to make 401(k) Contributions, would
     have been received by the Participant within two and one-half months after
     the close of the Plan Year."
 
     6.  Article 3.8(b)(ii) shall be deleted in its entirety and the following
shall be inserted in lieu thereof:
 
          "(ii) The income allocable to Excess Contributions shall be equal to
     the sum of the allocable gain or loss for the Plan Year for which the
     Excess Contributions were made, and the allocable gain or loss for the
     period between the end of such Plan Year and the date of distribution, as
     determined as follows:
 
          (A) The income allocable to a Participant's Excess Contributions for a
     Plan Year shall be determined by multiplying the total income for the Plan
     Year allocable to the Participant's 401(k) Contributions (including amounts
     treated as 401(k) Contributions) by a fraction, the numerator of which
     shall be the Participant's Excess Contributions, and the denominator of
     which shall be the total balance of the Participant's 401(k) Account
     (including amounts treated as 401(k) Contributions) as of
 
                                       80
<PAGE>   14
 
     the end of the Plan Year, reduced by the gain allocable to such Account for
the Plan Year, and increased by the loss allocable to such Account for the Plan
Year.
 
          (B) The allocable income shall include income for the period between
     the end of the Plan Year for which the Excess Contributions were made, and
     the date on which the corrective distribution is made to the Participant.
     For purposes of calculating the allocable income for this period, the
     Committee, in its sole discretion, shall select one of the two following
     methods, provided that the method selected shall be applied on a uniform
     and nondiscriminatory basis for all Participants with Excess Contributions:
 
          (1) The "fractional method," under which the income for the period
     between the end of the Plan Year and the last day of the month preceding
     the distribution date shall be multiplied by a fraction determined under
     the method described in Article 3.8(b)(ii)(A) above, or
 
          (2) The "10% method," under which 10% of the allocable income
     determined pursuant to Article 3.8(b)(ii)(A) above shall be multiplied by
     the number of calendar months that have elapsed between the end of the Plan
     Year and the distribution date. For purposes of determining the number of
     calendar months under the 10% method, a distribution made on or before the
     fifteenth day of a month shall be treated as having been made on the last
     day of the preceding month and a distribution occurring after the fifteenth
     day of a month shall be treated as having been made on the first day of the
     following month."
 
     7.  A new Article 3.8(b)(iii) shall be added as follows and Article
3.8(b)(iii) shall be redesignated as Article 3.8(b)(iv):
 
          "(iii) For purposes of this Article 3.8(b), if the Highly Compensated
     Employee's Deferral Percentage is determined by combining the 401(k)
     Contributions and compensation of all Family Members pursuant to Article
     3.7(c)(2), then the maximum amount of 401(k) Contributions permitted is
     determined in accordance with the leveling method set forth above in
     Article 3.8(b)(i)(B), and the Excess Contributions for the Family Members
     are allocated among the Family Members in proportion to their 401(k)
     Contributions."
 
     8.  A new Article 3.8(b)(v) shall be added as follows:
 
          "(v) If Excess Contributions and allocable income for a Plan Year are
     not corrected by distribution before the close of the first 2-1/2 months of
     the following Plan Year, the Employer shall be subject to a 10% excise tax
     on the amount of such Excess Contributions, pursuant to section 4979 of the
     Code. Such excise tax shall be
 
                                       81
<PAGE>   15
 
     due at the same time as the Employer's income tax for its taxable year with
or within which the Plan Year ends."
 
     9.  A new Article 6.2(c)(5) shall be added as follows and Article 6.2(c)(5)
shall be redesignated as Article 6.2(c)(6):
 
          "(5) Any Matching Contributions which are taken into account for
     purposes of determining a Participant's Deferral Percentage pursuant to
     Article 3.7(c)(4) for any Plan Year shall not be taken into account for
     purposes of determining such Participant's Contribution Percentage."
 
     10.  Article 6.3(c) shall be deleted in its entirety and the following
shall be inserted in lieu thereof
 
          "(c) The income allocable to Excess Matching Contributions shall be
     equal to the sum of the allocable gain or loss for the Plan Year for which
     the Excess Matching Contributions were made, and the allocable gain or loss
     for the period between the end of such Plan Year and the date of
     distribution or forfeiture, determined in accordance with the method set
     forth in Article 3.8(b)(ii), except that "Excess Matching Contributions,"
     "Matching Contributions," and "Matching Contributions Account" shall be
     substituted for "Excess Contributions," "401(k) Contributions," and "401(k)
     Account," respectively.
 
     11.  A new Article 6.3(e) shall be added as follows:
 
          "(e) For purposes of this Article 6.3, if the Highly Compensated
     Employee's Contribution Percentage is determined by combining the Matching
     Contributions and compensation of all Family Members pursuant to Article
     6.2(c)(2), then the maximum amount of Matching Contributions permitted is
     determined in accordance with the leveling method set forth above in
     Article 6.3(b)(2), and the Excess Matching Contributions for the Family
     Members are allocated among the Family Members in proportion to their
     Matching Contributions."
 
     12.  A new Article 6.5 shall be added as follows:
 
          6.5  Multiple Use of Alternative Limitation.
 
          (a) In order for the Plan to comply with the requirements of sections
     401(k) and 401(m) of the Code, the Plan must satisfy the tests set forth in
     Articles 3.7(a) and 6.2(a). However, the Employer must avoid the multiple
     use of the alternative limitation as set forth in Articles 3.7(a)(2) and
     6.2(a)(2) with respect to Highly Compensated Employees.
 
                                       82
<PAGE>   16
 
          (b) For purposes of this Article 6.5, a multiple use of the
     alternative limitation is present when all of the following conditions
     occur:
 
          (1) One or more Highly Compensated Employees of the Employer are
     eligible to participate in a cash or deferred arrangement subject to
     section 401(k) of the Code, and in the plan maintained by the Employer
     subject to section 401(m) of the Code;
 
          (2) The sum of the Actual Deferral Percentage of the entire group of
     eligible Highly Compensated Employees under such arrangement subject to
     section 401(k) of the Code and Actual Contribution Percentage of the entire
     group of eligible Highly Compensated Employees under such plan subject to
     section 401(m) of the Code exceeds the Aggregate Limit;
 
          (3) The Actual Deferral Percentage of the entire group of eligible
     Highly Compensated Employees under the arrangement subject to section
     401(k) of the Code exceeds 125 percent of the Actual Deferral Percentage of
     the entire group of eligible NonHighly Compensated Employees; and
 
          (4) The Actual Contribution Percentage of the entire group of eligible
     Highly Compensated Employees under such plan subject to section 401(m) of
     the Code exceeds 125 percent of the Actual Contribution Percentage of the
     entire group of eligible NonHighly Compensated Employees.
 
          (c) For purposes of the this Article 6.5, the Aggregate Limit is
     defined as the greater of:
 
          (1) The sum of:
 
          (A) 125 percent of the greater of the Relevant Actual Deferral
     Percentage or the Relevant Actual Contribution Percentage, and
 
          (B) Two (2) percentage points plus the lesser of the Relevant Actual
     Deferral Percentage or the Relevant Actual Contribution Percentage. In no
     event, however, shall this amount exceed twice the lesser of the Relevant
     Actual Deferral Percentage or the Relevant Actual Contribution Percentage;
     or
 
          (2) The sum of.
 
          (A) 125 percent of the lesser of the Relevant Actual Deferral
     Percentage or the Relevant Actual Contribution Percentage, and
 
                                       83
<PAGE>   17
 
          (B) Two (2) percentage points plus the greater of the Relevant Actual
     Deferral Percentage or the Relevant Actual Contribution Percentage. In no
     event, however, shall this amount exceed twice the greater of the Relevant
     Actual Deferral Percentage or the Relevant Actual Contribution Percentage.
 
          (d) For purposes of this Article 6.5, the term "Relevant" Actual
     Deferral Percentage and term "Relevant" Actual Contribution Percentage mean
     the Actual Deferral Percentage or the Actual Contribution Percentage of the
     eligible group of Non-Highly Compensated Employees.
 
          (e) In the event a multiple use of the alternative limitation as
     described in Article 6.5(b) is present, such multiple use shall be
     corrected by reducing the Actual Contribution Percentage of the Highly
     Compensated Employees so that the combined Actual Deferral Percentage and
     the Actual Contribution Percentage does not exceed the Aggregate Limit. The
     required reduction shall be treated as an Excess Matching Contribution as
     described in Article 6.3(b). The method of correct to be used to reduce the
     Actual Contribution Percentage shall be the method as set forth in Article
     6.3(b)(2)."
 
     13. Article 9.1 shall be deleted in its entirety and the following shall be
inserted in lieu thereof:
 
          "9.1 Allocation of 401(k) Contributions.  Any 401(k) Contributions

     Article 12.2, except that if the value of the Participant's Accounts
     exceeds $3,500, no distribution shall be made prior to the Participant's
     Normal Retirement Date without the prior written consent of the Participant
     and, when applicable, the Participant's spouse."
 
     15. Effective January 1, 1990, the last sentence of Article 12.4 of the

     balance during the 1 year period ending on the day before the day on which
     the current loan is made. For purposes of determining the Participant's
     highest outstanding loan balance, all loans made to the Participant from
     the Plan and any other qualified plan maintained by the Company or a
     Related Company shall be aggregated.
 
          (2) 50% of the Participant's vested interest in his Accounts, reduced
     in either case by the current outstanding balance of all other loans to the
     Participant from the Plan and any other qualified plan maintained by the
     Company or a Related Company.
 
          Notwithstanding the foregoing, the principal amount of a loan from the
     Plan to the Participant may not exceed seventy percent (70%) of the vested
     account balance of the Participant's Accounts (as of the last Valuation
     Date for which valuation is available at the time of such loan, less
     subsequent distributions and outstanding loans) which are invested in
     investment funds other than a money market fund and one hundred percent
     (100%) of the vested account balance of the Participant's Accounts (as of
     the last Valuation Date for which valuation is available at the time of
     such loan, less subsequent distributions and outstanding loans) which are
     invested in a money market fund.
 
          (b) Loans shall be made available to all Participants on a reasonably
     equivalent basis.
 
          (c) Loans must be secured by the Participant's vested interest in his
     Accounts.

<PAGE>   19
 
          (d) Loans must be evidenced by the borrowing Participant's promissory
     note for a fixed term not to exceed five (5) years unless the proceeds of
     the loan are used to acquire any dwelling unit which within a reasonable
     time is to be used (determined at the time the loan is made) as a principal
     residence of the Participant, in which case such loan must be required to
     be repaid within thirty (30) years (effective June 1, 1990, ten (10)
     years). Loans for the acquisition of the Participant's principal residence
     are referred to herein as Residence Loans and all other loans are to be
     referred to as General Loans.
 
          (e) A loan shall bear a reasonable rate of interest and require
     regular, periodic repayment through substantially level amortization and
     payments not less frequently than quarterly over the life of the loan.
 
          (f) A loan shall not be made is such loan would constitute a
     prohibited transaction under the applicable sections of ERISA and the Code,
     and the regulations promulgated thereunder.
 
          (g) A Participant may not obtain more than two loans from the Plan in
     any Plan Year.
 
          (h) Loans shall be for the minimum amount of Five Hundred Dollars
     ($500.00).
 
          (i) Loans may be prepaid in full without penalty. No partial payment
     is permitted.
 
          (j) Repayment of all loans shall be through payroll deduction, unless
     the Participant is on an unpaid leave of absence or on disability leave, in
     which case repayment of the loan may be made by personal check. A
     Participant may not terminate his payroll deduction authorization.
 
          (k) Loans shall become immediately due and payable on the
     Participant's termination of employment with the Employer, unless the
     Participant is a "party in interest" within the meaning of Section 3(14) of
     ERISA.
 
          (1) Loans may be immediately due and payable, in the sole discretion
     of the Committee, if the Participant fails to make any installment when
     due.
 
          (m) In the event of default by a Participant, such Participant's
     Accounts may be offset by the outstanding loan balance at the time the
     Participant becomes entitled to a distribution from the Plan.

     policies as shall be adopted from time to time by the Committee which, upon
     adoption, shall constitute part of the Plan and which shall include such
     provisions as may be required by final regulations promulgated by the

          Re: Acquisition of Interests in C.T. Montague I and II, L.P.

Gentlemen;

         As of June 17, 1991, C.T. Properties, Inc. (the "General Partner"), as
general partner, and Cadence Design Systems, Inc. ("Cadence"), Montague
Investors, L.P. ("Montague") and David M. Thede ("Thede"), as limited partners,
entered into a limited partnership agreement and thereby formed C.T. Montague
I, L.P. (the "Partnership"). Cadence and Thede are the sole shareholders of the
General Partner, which has two directors.  Thede is the President and one
director of the General Partner; H. Raymond Bingham, Executive Vice President
and Chief Financial Officer of Cadence, is the Secretary and the other director
of the General Partner. Thede and Cadence entered into a voting agreement dated
as of June 14, 1991 (the "Voting Agreement") in order to facilitate certain
management functions of the General Partner.

         The General Partner has a one percent interest in the Partnership as a
general partner; Cadence, Thede and Montague have, respectively, 46.5%, 22.5%
and 30% limited partner interests in the Partnership.

         The Partnership owns land improved with an office building (the
"Project"), which is leased to Cadence and encumbered by a mortgage in favor of
the Bank of Boston.

The General Partner, as general partner, and Thede and Cadence, as limited
partners, are also partners in C.T. Montague lI, L.P. (the "Second
Partnership"), which owns unimproved land adjacent to the Project.

         By this letter, Cadence offers to acquire, on the terms and conditions
set forth below, all of Thede's ownership interests in the Partnership, the
Second Partnership and the General Partner and all of Montague's ownership
interests in the Project (which Montague will hold, at Closing, after
redemption of Montague's entire interest in the Partnership in exchange for
conveyance to Montague of an undivided ownership interest in the Project). By
accepting this offer and consummating the transactions contemplated hereby,
Cadence will be the only limited partner of the Partnership and Second
Partnership and the only shareholder of the General Partner, and all parties
will waive any prior claims against the others, the General Partner, the
Partnership and the Second Partnership.





                                       93
<PAGE>   2
         1.   Price, Cadence will pay Thede, in cash at the Closing, $3,290,299
subject to adjustment as provided below (the "Thede LP Price") for his entire
limited partner interest in the Partnership (the "Thede LP Interest") and
$74,619 subject to adjustment as provided below (the "Thede GP Price") for his
entire stock interest in the General Partner (the "Thede GP Interest"). Cadence
will pay Montague in cash at the closing, $7,841,972 subject to adjustment as
provided below (the "Montague Price") for all of the Montague Project Interest
(as defined in Paragraph 2 below). As of March 15, 1994, the Partnership will
have approximately $3,700,000 of cash on hand.  Cadence will also pay Thede in
cash at the Closing $1,300,000, without further adjustment, for his entire
limited partner interest in the Second Partnership (the "Thede SP Price").  The
consideration described above and the mutual covenants set forth below are
acknowledged by all parties to be adequate. If, through no fault of Thede or
Montague, the Closing occurs after March 15, 1994, the Thede LP Price, the
Thede GP Price and the Montague Price will be increased by, respectively,
$902.35, $20.46, and $2,149.68 for each day of such delay.

         2. Exchange. The Partnership will convey to Montague, prior to Closing
and in complete redemption of Montague's entire interest in the Partnership
(the "Montague LP Interest"), a 30% undivided interest in the Project (the
"Montague Project Interest").   Montague will convey its interest in the
Partnership back to the Partnership by execution and delivery of a redemption
in the form attached hereto as Exhibit A-1; and the Partnership will convey the
Montague Project Interest to Montague by execution and delivery of a standard
form grant deed. At the Closing, Montague will consummate a tax deferred
exchange for the Montague Project Interest pursuant to Section 1031 of the
Internal Revenue Code (the "Exchange"); provided that Montague will pay all
expenses in connection with the Exchange and will indemnify Cadence, Thede and
the Partnership against any adverse tax consequences or governmental claims
resulting from the Exchange (including any and all transfer taxes); and
provided further that the Exchange will not delay the Closing.  Cadence, Thede
and the Partnership agree to cooperate with and accommodate Montague in
connection with the Exchange.

         Notwithstanding any other provision of this agreement, Montague will
have the right and option, exercisable by notice to Cadence and the Partnership
at any time prior to the conveyance of the Montague Project Interest to
Montague as provided above, to sell the Montague LP Interest to Cadence in lieu
of consummating the Exchange, in which event at the Closing (i) Montague will
convey the Montague LP Interest to Cadence by execution and delivery of an
assignment in the form attached hereto as Exhibit A-5,  (ii) Cadence will pay
the Montague Price to Montague by cashiers check or wire transfer as Montague
may elect, and (iii) Paragraphs 3(a), 3(b) and 6(d)(3) shall be deemed modified
accordingly.

         3.   Closing. Subject to the provisions of Paragraph 10 below, the
Closing will take place at 1:30 PM on March 15, 1994,  at the Cadence offices;
provided that the date, time and/or place of the Closing may be changed by
mutual agreement of all parties, and provided further that if any of the
conditions to the Closing set forth in Paragraph 6 below are not satisfied by
March 15, 1994, the party to be benefited by such unsatisfied conditions shall
have the right and option, but not the obligation, to extend the date of the
Closing until a weekday selected by such party that is no more than five days
following the subsequent satisfaction or waiver of such condition.

reviewed the preliminary title report for the Project attached hereto as
Exhibit E-1 (the "Title Report") and the UCC search reports for the Partnership

         5. Representations and Warranties. Each of the parties makes the
representations and warranties set forth for it below, hereby certifying that
such representations and warranties are true and complete as of the date hereof
and/or will be true and complete at the Closing, and acknowledges that the
other parties will rely upon such representations and warranties in entering

representations and warranties will survive the Closing; provided that the
representations and warranties in Subparagraph (a)(3) below will terminate one
year following the Closing.

                   a.     Thede.   Thede represents and warrants that:

                            (1)   He owns the Thede SP, LP and GP Interests

to or otherwise bound by any agreements imposing a material obligation on the
General Partner, the Second Partnership or the Partnership other than the
contracts identified in the List of Material Contracts attached hereto as
Exhibit F, complete copies of which contracts have been delivered to Cadence

than the usual obligations incurred in the ordinary course of business),
pending claims or governmental actions other than as disclosed in the Title
Report, the UCC Reports or the Schedule of Exceptions to Representations and
Warranties attached hereto as Exhibit G.  As used herein, "material" means
involving an obligation exceeding $10,000 within any one year period or a
liability, claim or action exceeding $10,000.

                   b.     Montague.  Montague represents and warrants that:

                        (1)       It owns the Montague LP Interest and,
assuming the Partnership conveys the Montague Project Interest to Montague
pursuant to Paragraph 2 above, it will own the Montague Project Interest, in
each case free and clear of all forms of claims by third parties, including
governmental agencies, other than, in the case of the Montague Project
Interest, any liens, claims or encumbrances affecting the Partnership's title
to the Project at the time the Montague Project Interest is conveyed to
Montague pursuant to Paragraph 2 above.

                      (2)   It has the requisite authority, and the consent of
any third parties whose consent is required (including general and limited

convey the Montague LP Interest back to the Partnership in exchange for
conveyance from the Partnership of the Montague Project Interest, and to cause
the Montague Project Interest to be conveyed to Cadence under the terms of this
agreement.

                          (3)     All requisite partnership action of Montague
necessary to authorize and implement this transaction has been duly taken.

                   c.     Cadence.   Cadence represents and warrants that:

                          (1)     It has the requisite authority, and the
consent of any third parties whose consent is required, to enter into this
agreement and to purchase and pay for the Thede SP, LP and GP Interests and the
Montague Project Interest under the terms of this agreement.

an accredited investor within the meaning of Regulation D under the Securities

account, for investment, without a view to distribution of the same.

        d.     Partnership.   Partnership represents and warrants that:

                          (1)     It has the requisite authority, and the
consent of any third parties whose consent is required, to enter into this
agreement and to convey the Montague Project Interest to Montague in exchange
for redemption of Montague's entire interest in the Partnership under the terms
of this agreement.

    of the occurrence) of simultaneous delivery of all items to be delivered at
    the Closing pursuant to Paragraph 3 above.

                 b.       Thede.  Thede's obligations under this agreement are

                 c.       Montague.  Montague's obligations under this

    this agreement are further conditioned on the truth and completeness (or
    the Partnership's waiver of the truth and completeness) of all
    representations and warranties of Thede, Montague and Cadence under this
    agreement.

         7.      Operations Through Closing.  Thede represents and covenants,
    in his capacity as President of the General Partner, that since February
    28, 1994 he has conducted the business of the General Partner and the
    General Partner has conducted the business of the Partnership in the
    ordinary course, and that through the Closing he will continue to conduct
    the business of the General Partner and will cause the General Partner to
    continue to conduct the business of the Partnership in the ordinary course.
    Upon the Closing, the management agreement between the





                                       97
<PAGE>   6
Partnership and Thede will terminate and the management fees which have accrued
to that date will be paid by the Partnership in the ordinary course of
business.

         8.      Confidentiality.  All parties, unless under compulsory process
    or obligation to disclose in connection the provisions of the Securities
    and Exchange Act of 1934, will maintain the confidentiality of the price
    provisions of this agreement, and no party will issue a press release in
    connection with this proposed transaction without the prior consent of all
    other parties.   This covenant will not limit a party's ability to share
    relevant information with his or its professional advisors, such as
    attorneys and accountants, and with the Project's lender, however.
    Moreover, and notwithstanding any contrary provision of this agreement,
    this covenant will survive any termination of this agreement.

         9.      Thede Consultation.  Following the Closing, Thede will
    provide, at no charge, up to two days of consultation with Cadence's
    project manager to assist an orderly transition of the management of the
    General Partner, the Partnership and the Project.

         10.     Termination.  This agreement may be terminated (i) by the
    mutual agreement of all parties or (ii) if any of the conditions to the
    Closing set forth in Paragraph 6 above are not satisfied and not waived in
    accordance herewith, by any party to be benefited by such unsatisfied and
    unwaived condition, in which case the termination shall occur upon notice
    by such party to all other parties.  This agreement will automatically
    terminate at 5:00 p.m. on March 31, 1994, unless the Closing occurs prior
    thereto.  Upon termination of this agreement, all parties will be relieved
    of all further obligations hereunder; provided that any party whose breach
    of this agreement resulted in such termination shall not be relieved of any
    liability resulting therefrom.

         11.     Miscellaneous.  This agreement constitutes the entire
    agreement between the parties on the subject matter hereof and may be
    amended only by a written amendment signed by all parties.  All references
    to the agreement will include the provisions of the exhibits attached to
    this agreement.  This agreement will be governed by California law as
    applied to contracts entered into between residents of California.  The
    parties acknowledge that specific performance is an appropriate remedy for
    any breach of this agreement.  All parties will bear their own legal
    expenses in connection with the preparation of this agreement and any
    modifications and the effectuation of the transactions contemplated hereby.
    This agreement may be signed in counterparts, all of which together shall
    constitute a single agreement.  The validity of any portion of this
    agreement will not invalidate any other portion; provided that in no event
    will Cadence be obligated to acquire less than all interests in the
    Project, Second Partnership and Partnership.  No waivers permitted by this
    agreement shall be implied by conduct.  Time is of the essence in this
    agreement.  The provisions of this agreement may not be introduced into
    evidence by any party hereto in any matter of dispute between them, except
    in connection with a claim of breach of this agreement.  In the event of
    any inconsistency between the provisions of this agreement and the
    provisions of the limited partnership agreements or the Voting Agreement,
    then the provisions of this agreement will supersede such other provisions.
    Finally, the parties agree to execute such other documents as may be
    necessary in the future without additional risk or expense in order to
    implement the provisions of this agreement.

         If the offer set forth above is acceptable, please so indicate by
    executing the enclosed copy of this letter where indicated below and
    returning it to me.  Upon receipt of copies of this letter signed by all
    parties by 3:00 p.m. on March 14, 1994, this letter will constitute a
    binding agreement among all parties; otherwise, this offer will lapse.

any party now has, owns, or holds or at anytime heretofore ever had, owned, or
held, or could, shall, or may hereafter have, own, or hold, against any other
based on or arising out of any matter, cause, fact, transaction, act, or
omission whatsoever occurring or existing at any time prior to and including
the effective date hereof, bearing any logical or factual connection whatsoever
to the limited partnership agreements for C.T. Montague I and II, L.P., the
development agreements between Thede or Thede Properties Inc., the Partnership
and the Second Partnership, the management agreement dated June 17, 1991
between Thede and the Partnership and the Voting Agreement and the By-laws with
respect to the General Partner (collectively the "Released Agreements"), either
party's performance, nonperformance or breach of the Released Agreements, and
any liabilities arising or alleged to have arisen under or in the course of
performance under the Released Agreements (all of which are hereinafter
referred to as and included within the "Released Matters").

                 Covenant Not To Sue or Offset  Each party agrees that it will
not bring, commence, institute, maintain, prosecute or voluntarily aid any
action at law, proceeding in equity, or otherwise prosecute or sue the other
party hereto or its agents, representatives, heirs, partners, directors,
officers, employees, servants, affiliates, subsidiaries, stockholders,
predecessors, successors and assigns, or any person acting for, through, under
or in concert with any of the foregoing, either affirmatively or by way of
cross-complaint, defense, equitable offset or counter-claim or by any other way
or manner at all, in any court, on any alleged claims, demands, liabilities,
causes of action, suits, debts, liens, contracts, agreements, promises, losses,
damages, costs or expenses, of any nature whatsoever, known or unknown, fixed
or contingent, arising out of the Released Matters.

                 General Release.  Each party acknowledges that it is familiar
with Section 1542 of the Civil Code of the State of California, which provides
as follows:

             "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT

THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY
AFFECTED HIS SETTLEMENT WITH THE DEBTOR."

EACH PARTY WAIVES AND RELINQUISHES ANY RIGHT OR BENEFIT WHICH IT HAS OR MAY
HAVE UNDER SECTION 1542 OF THE CIVIL CODE OF THE STATE OF CALIFORNIA RELATING
TO THE RELEASED MATTERS. In connection with such waiver and relinquishment,
each party acknowledges that it is aware that it or its attorneys or agents may
hereafter discover claims or facts in addition to or different from those which
they now know or believe to exist with respect to the subject matter of the
Released Matters or the other party hereto, but that it is each party's
intention hereby fully, finally, and forever to settle and release all Released
Matters, disputes and differences, known or unknown, suspected or unsuspected,
which now exist, may exist or heretofore, may have existed between the parties
relating to the Released Matters, except as otherwise expressly provided
herein. In furtherance of this intention, the mutual releases herein given
shall be and remain in effect as a full and complete general release
notwithstanding the discovery or existence of any such additional or different
claim or fact.

                 Authorized Release.  Each party warrants and represents that
it is the sole and lawful owner of all rights, title and interest in and to all
the Released Matters, that it has the right and the authority to execute this
Agreement and that it has not heretofore voluntarily, by operation of law, or
otherwise, assigned or transferred or purported to assign or transfer to any
person whatsoever any Released Matters or any part or portion thereof or any
claim, demand or right against the other party.

                 Indemnity for Undisclosed Assignment of Claims.  Each party
shall indemnify and hold the others harmless from and against any claim,
demand, damage, debt, liability, account, obligation, cost, expense, lien,
action, or cause of action (including payment of reasonable attorneys' and
experts' fees and costs actually incurred whether or not litigation is
commenced) based on or in connection with or arising out of any assignment or
transfer or purported or claimed assignment or transfer by such party of the
type referred to in the preceding paragraph (all of which are hereinafter
referred to as the "Claim"). Each party's right to indemnification under this
paragraph is subject to it promptly giving the indemnifying party notice of any
Claim, including in such notice a brief description of the facts upon which the
Claim is based and the amount thereof.

                 No Admissions.  Nothing contained herein shall be construed as
an admission by any party of any liability of any kind to any other party. Each
party expressly denies that it is in any way liable or indebted to the other
party, except with respect to obligations created or expressly renewed by this
Agreement and the letter agreement.  

                Informed Consent to Release.  Each party acknowledges to each
other party that it has been represented by legal counsel of its own
choice throughout all of the negotiations which preceded the execution of this
Agreement, and that each party has had ample opportunity to have this Agreement
and the releases contained herein reviewed by its respective legal counsel.
Each party further acknowledges that it and its counsel has had adequate
opportunity to make whatever investigation or inquiry deemed necessary or
desirable in connection with this Agreement and the Released Matters prior to
the execution hereof.
