                                     General

Mentor Graphics Corporation manufactures, markets and supports software and
hardware Electronic Design Automation ("EDA") products and provides related
services which enable engineers to design, analyze, place and route, and test
the components of electronic systems. Mentor Graphics has recently expanded its
product offerings beyond traditional EDA to include (1) intellectual property
("IP") products and services intended to increase design efficiency by
delivering standard, reusable functions for the design of hardware components
and (2) embedded software development and system verification tools intended to
shorten product time to market by allowing for simultaneous development and
testing of hardware and embedded software. Mentor Graphics markets its products
primarily to large companies in the communications, computer, semiconductor,
consumer electronics, aerospace and transportation industries. Customers use
Mentor Graphics' software in the design of such diverse products as
supercomputers, automotive electronics, telephone switching systems, cellular
base stations and handsets, computer network hubs and routers, signal processors
and personal computers. Mentor Graphics sells and licenses its products
primarily through its direct sales force in North America, Europe and Asia, and
through distributors in territories where the volume of business does not
warrant a direct sales presence. Mentor Graphics was incorporated in Oregon in
1981 and its common stock is traded in the NASDAQ National Market System under
the symbol MENT. Mentor Graphics' executive offices are located at 8005 S.W.
Boeckman Road, Wilsonville, Oregon 97070-7777. The telephone number at that
address is (503) 685-7000.

                                    Products
EDA Products

Mentor Graphics' EDA products support the development of integrated circuits
("ICs"), application specific integrated circuits ("ASICs"), field programmable
gate arrays ("FPGAs"), printed circuit boards ("PCBs") and multichip modules
("MCMs").

Mentor Graphics' IC design products allow designers to specify an IC design, add
structures for testing the design to remove errors, "layout" the electrical
components of the design in a way that balances IC performance and the size of
the IC used, and finally, create output which is used to direct the
manufacturing and testing of the IC. "ICs" are high performance circuits with
customized logic layers. Mentor Graphics products within the IC design flow
include IC design and layout tools such as MS Analyzer, Cell Builder, GDT, IC
Station, MicroRoute, QuickHDL, FastScan, FlexTest, and SimExpress, as well as
power management and analog and analog/mixed signal design solutions. Mentor
Graphics is able to link its ASIC/FPGA and MCM/PCB design products with its IC
design products to create a continuum of automation from the individual
component level up to the fully-integrated end-product.

Mentor Graphics' ASIC/FPGA design products allow designers to create and verify
designs to ensure that they possess the required performance and functionality
and to create output which will allow the design to be manufactured and tested.
"ASICs" are special integrated circuits with 


                                       2
<PAGE>
standard logic layers which are customized by interconnect layers. The standard
logic layers allow ASICs to be designed faster and manufactured at a lower cost
for smaller unit volumes than traditional ICs. "FPGAs" are circuits that can be
programmed to include different functionality at the point of manufacturing or
during system startup. Mentor Graphics' ASIC/FPGA products include Renoir,
QuickHDL, BSD Architect, DFTAdvisor, FastScan, FlexTest, Leonardo, Galileo,
SimExpress, FPGA Station and Idea Station.

Mentor Graphics' PCB/MCM design tools allow designers to select from a library
of parts to be included in the PCB/MCM, to simulate and test the performance of
the PCB/MCM, to test for manufacturability, to analyze thermal and signal
integrity, and to output data which will allow the PCB/MCM to be manufactured.
"PCBs", a common way of packaging electronic circuits, are epoxy type "boards"
upon which ICs, ASICs and discrete components such as resistors and capacitors
are mounted. "MCMs" may be thought of as several ICs or ASICs mounted together
in a single package. Products within the MCM and PCB design flows include Board
Station, MCM Station, Interconnect Synthesis, AutoTherm MCM, Logical Cable,
Physical Test Manager: SITE, Manufacturing Advisor/PCB and EngineerView.

Intellectual Property and Embedded Software Development Products

Mentor Graphics believes that the demand for tools to develop increasingly
complex electronic systems cannot be entirely satisfied with traditional EDA
tools. Under its Integrated System Design (ISD) strategy, Mentor Graphics
supplements its EDA products with products and services which address the rapid
development of complex systems through design re-use and the integration of
hardware and embedded software development.

Mentor Graphics' IP products and services are intended to increase engineering
productivity through the use of predefined, and preverified "building blocks" of
frequently used circuit functions for the design of hardware components. This
so-called "design reuse" frees designers to focus on optimizing system
architecture and developing proprietary functionality. Mentor Graphics believes
that companies which integrate IP into their design methodology can expect
better quality products at lower costs and faster time-to-market. IP now
available from Mentor Graphics includes a wide variety of functions key to the
design of consumer, computer and communications products. These include foundry
libraries, memories, datapath elements, processors, Universal Serial Bus (USB),
Viterbi and Reed-Solomon error correction decoders, MPEG-2, T1/E1 and Ethernet.

Embedded software development tools are provided by Mentor Graphics' Microtec
subsidiary. Embedded software controls the function of hardware components
dedicated to specialized tasks of such common consumer products as VCRs,
telephones and fax machines. Embedded software is used in a wide range of other
products in the aerospace, communications, medical instrumentation,
transportation, computer, industrial and consumer markets. Microtec's embedded
software development tools include the VRTX real-time operating system, the XRAY
family of debugger products and other software development tools including
compilers, assemblers, linkers and simulators.

Mentor Graphics' co-verification tools provide a means to verify the hardware
and embedded software comprising an electronic system against each other without
having to build a hardware prototype. Mentor Graphics believes this improves the
efficiency of its customers' product development cycle by giving customers more
time to fix software bugs and resolve hardware-software interface errors and
reduce the risk that a design problem will cause a significant delay in the
project schedule. The Company's co-verification products are marketed as the
Seamless Co-Verification Environment family of products.


                                       3
<PAGE>
                                    Platforms

Mentor Graphics' software products run primarily on UNIX workstations in a broad
range of price and performance levels, including workstations manufactured by
Hewlett-Packard Company and Sun Microsystems, Inc. These computer manufacturers
have a substantial installed base of workstations, and make frequent
introductions of new products. Mentor Graphics introduced four families of
products for Windows NT on personal computers in 1996.

                             Marketing and Customers

Mentor Graphics' marketing emphasizes its ISD strategy for the integration of
both hardware and software development for electronic systems, its IP tools, a
direct sales force and large corporate account penetration in the
communications, computer, consumer electronics, semiconductor, aerospace, and
transportation industries.

Mentor Graphics sells and licenses its products primarily through its direct
sales force in North America, Europe and Asia. Mentor Graphics also licenses its
products through distributors in territories where the volume of business is not
sufficient to warrant a direct sales presence. During the years ending December
31, 1996 and 1995, sales outside of North America accounted for 46 and 48
percent, respectively, of total sales. Additional information relating to
foreign and domestic operations is contained in Note 14 of Notes to Consolidated
Financial Statements on page 37 of the 1996 Annual Report to Shareholders and is
incorporated by this reference.

No material portion of Mentor Graphics' business is dependent on a single
customer. Mentor Graphics has traditionally experienced some seasonal
fluctuations in receipts of orders, which are typically stronger in the second
and fourth quarters of the year. As is typical of many other companies in the
electronics industry, Mentor Graphics generally ships its products to customers
within 180 days after receipt of an order, and a substantial portion of
quarterly shipments tend to be made in the last month of each quarter.

Mentor Graphics' backlog of firm orders was approximately $74.0 million on
December 31, 1996 as compared to $53.9 million on December 31, 1995. This
backlog includes products not shipped and unfulfilled professional services and
training. Mentor Graphics does not track backlog for support services. Support
services are typically delivered under annual contracts which are accounted for
on a prorata basis over the twelve month term of each contract. Substantially
all of the December 31, 1996 backlog of orders is expected to ship during 1997.

Mentor Graphics generally sells and licenses its products and some third party
products pursuant to purchase and license agreements. Mentor Graphics schedules
deliveries only after receipt of purchase orders under these agreements.

                            Manufacturing Operations

Mentor Graphics' manufacturing operations primarily consist of reproduction of
Mentor Graphics' software and documentation. In North America, manufacturing is
substantially outsourced, with distribution to Western Hemisphere customers
occurring from major west coast sites. Distribution centers in The Netherlands,
Japan and Singapore serve their respective regions. Mentor Graphics' SimExpress
line of accelerated verification products, which is comprised of both hardware
and software, is currently manufactured in France. The Company anticipates that
it will also manufacture this product line in the United States in 1997.

                               Product Development

Mentor Graphics' research and development is focused on continued improvement of
its existing products and the development of new products. During the years
ended December 31, 1996, 1995 


                                       4
<PAGE>
and 1994, Mentor Graphics expensed approximately $92,905,000, $86,782,000 and
$81,231,000 respectively, and capitalized approximately $5,691,000, $8,129,000
and $5,718,000, respectively, related to product research and development.
Mentor Graphics also seeks to expand existing product offerings and pursue new
lines of business through acquisitions. Acquisitions accommodate Mentor
Graphics' focused strategic requirements including filling gaps in existing
products or technologies, eliminating dependencies on third parties and
providing Mentor Graphics with an avenue into new lines of business. Mentor
Graphics' future success depends on its ability to develop or acquire
competitive new products which satisfy customer requirements.

                                    Suppliers

Mentor Graphics seeks to provide its customers with software and IP that
addresses customers' electronic system design processes. Supplier products fill
gaps in Mentor Graphics' existing product lines and allow it to offer products
which are needed by customers but which are not central to Mentor Graphics'
business. Supplier agreements are also used by Mentor Graphics to explore
possible new lines of business. Although Mentor Graphics has supplier agreements
with several large customers who do not wish to develop a specific internal
technology into a commercial product, Mentor Graphics' suppliers are typically
small niche companies which do not have adequate distribution channels for their
products. Mentor Graphics maintains three different types of supplier
relationships: (i) a simple remarketing relationship where the supplier's
product is added to Mentor Graphics' price list and drop shipped to the customer
directly from the supplier; (ii) a partial integration relationship where the
supplier's object code is packaged and shipped with other Mentor Graphics'
products to the customer; and (iii) a fully integrated relationship where Mentor
Graphics modifies or enhances the supplier's product before packaging and
delivering it to the customer.

Supplier agreements are typically multi-year agreements with royalty payments
based on a percentage of product revenue. The agreements generally require an
escrow of the supplier's source code. Customer support for supplier products is
usually provided by Mentor Graphics with the supplier providing backup support
and research and development in the event of a problem with the product itself.

                         Customer Support and Consulting

Mentor Graphics has a worldwide organization to meet its customers' needs for
software support; the Company offers support contracts providing software
updates and support. Most of Mentor Graphics' customers have entered into
software support contracts.

Mentor Graphics believes that consulting services is an expanding segment of its
business. The Company's consulting group was established in 1987. Its mission is
to team with customers' design groups to increase productivity and reduce costs
by assisting customers with methodology and process changes, tool refinements,
design implementation and integration services. Mentor Graphics has a worldwide
team of consulting professionals available for on-site customer consultation
providing software and services for design data management, electronic parts
data creation, process automation, technology adoption, and ASIC, IC, MCM and
PCB design implementation.

<PAGE>
                                   Competition

The markets for Mentor Graphics' products are competitive and have been
characterized by rapid technological advances in application software, operating
systems and hardware. Mentor Graphics' principal EDA competitors are Cadence
Design Systems Inc., Synopsys Inc., Avant! Corporation, Viewlogic Systems Inc.,
Zuken-Redac, Quickturn Design Systems, Inc. and numerous small companies. Mentor
Graphics' principal competitors for embedded software development tools are Wind
River Systems Inc., and Integrated Systems Inc.

Some of Mentor Graphics' competitors may have greater financial and marketing
resources than Mentor Graphics. However, Mentor Graphics believes the main
competitive factors affecting its business are breadth and quality of
application software, product integration, ability to respond to technological
change, quality of a company's sales force, price, size of the installed base,
level of customer support and professional services. Mentor Graphics believes
that it generally competes favorably in these areas. Mentor Graphics can give no
assurance, however, that it will have financial resources, marketing,
distribution and service capability, depth of key personnel or technological
knowledge to compete successfully in its markets.

                                    Employees

Mentor Graphics and its subsidiaries employed approximately 2,500 persons full
time as of December 31, 1996. Mentor Graphics' success will depend in part on
its ability to attract and retain employees who are in great demand. Mentor
Graphics continues to enjoy good employee relations.

                              Patents and Licenses

Mentor Graphics owns numerous United States and foreign patents covering
portions of its technology. Mentor Graphics is currently seeking to patent more
of the inventive technology which Mentor Graphics believes gives it a
competitive advantage. Mentor Graphics presently has patent applications pending
and intends to file additional patent applications in the future. While Mentor
Graphics believes the pending applications relate to patentable devices, there
can be no assurance that any patent will be issued or that any patent can be
successfully defended. Although Mentor Graphics believes that patents are less
significant to the success of its business than technical competence, management
ability, marketing capability and customer support, Mentor Graphics believes
that software patents are becoming increasingly important in the software
industry.

Mentor Graphics regards its application software as proprietary and attempts to
protect it with copyrights, trade secret laws, and internal non-disclosure
safeguards, as well as patents, when appropriate, as noted above. Mentor
Graphics typically incorporates restrictions on disclosure, usage and
transferability into its agreements with customers and other third parties.


ITEM 2.  PROPERTIES

Mentor Graphics' Wilsonville, Oregon facilities are located in six owned
buildings on about 90 acres and take up approximately 390,000 square feet. All
corporate functions, as well as a majority of research and development and
domestic activities, operate from this site.

Mentor Graphics leases additional space in San Jose, California, and in various
locations throughout the United States and in other countries, primarily for
sales and customer service operations. Mentor Graphics believes that it will be
able to renew or replace its existing leases as they expire and that its current
facilities will be adequate through at least 1997.


                                       6

ITEM 3.  LEGAL PROCEEDINGS

During 1995, Mentor Graphics filed suit in U.S. Federal District Court against
Quickturn Design Systems, Inc. (Competitor) for a declarative judgment on
non-infringement, invalidity and unenforceability of three of Competitor's
patents as these patents relate to products of Meta System SRL (Meta), a French
company acquired by Mentor Graphics in 1996 which manufactures and sells
computers used for accelerated verification of hardware designs. In connection
with this litigation, Competitor filed an administrative complaint with the U.S.
International Trade Commission (ITC) in 1996 seeking to hinder the distribution
of Meta accelerated verification products, marketed by Mentor Graphics as
SimExpress, in the United States. The ITC has since issued a temporary ruling
allowing the importation of Meta accelerated verification products to the U.S.,
provided Mentor Graphics posts a bond for each sale. Mentor Graphics believes
that the ultimate resolution of its disputes with Competitor will not have a
material adverse impact on the Company's financial position or results of
operation.

Mentor Graphics is also a party to other legal actions arising out of the normal
course of business, none of which are expected to have a material effect on the
Company's financial position or results of operation.

each of the years in the three-year period ended December 31, 1996, which are

where the volume of business does not warrant a direct sales presence. In
addition to its corporate offices in Wilsonville, Oregon, the Company has sales,
support, software development and professional services offices worldwide.

Recent Mergers and Acquisitions

     Acquisitions of complementary businesses are an integral part of the
Company's overall business strategy. Acquisitions accommodate the Company's
focused strategic requirements by filling gaps in existing products or
technologies, eliminating dependencies on third parties and providing the
Company with an avenue into new lines of business and new distribution channels.
The Company will continue to evaluate make-versus-buy alternatives, which may
result in additional business combinations in 1997. There can be no assurance
that products, technologies and businesses of acquired companies, or the
technical and sales personnel of such companies, will be effectively assimilated
with those of the Company.

     In 1996, the Company completed nine business combinations, two of which
were accounted for as pooling of interests and seven of which were accounted for
as purchases. The Company purchased dQdt, Inc. (dQdt), Meta Systems, (Meta),
Seto Software GmbH (Seto), Royal Digital Centers, Inc. (Royal Digital), Open
Networks Engineering, Inc. (ONE), Systolic Technology, LTD (Systolic), and CAE
Technology, Inc. (CAE) in April 1996, May 1996, June 1996, August 1996, November
1996, November 1996 and December 1996, respectively. The total purchase price
including acquisition expenses for all 1996 purchase acquisitions was $40,708.
In connection with all purchase acquisitions, the Company recorded one-time
charges to operations for the write-off of each enterprise's in-process product
development which had not reached technological feasibility. The purchase
accounting allocations resulted in charges for in-process research and
development (R&D) of $26,234, goodwill capitalization of $5,517, and technology
capitalization of $8,957.

     In January, 1996, the Company completed the acquisition of Microtec
Research, Inc. (Microtec), pursuant to a merger accounted for as a pooling of
interests. Accordingly, the results of Microtec are included in the Company's
Consolidated Financial Statements for all periods presented. A total of 6,223
shares of the Company's common stock were issued in the transaction. Merger
expenses of $4,410 were incurred associated with the elimination of duplicate
facilities, severance costs, the write-off of certain property and equipment and
legal and accounting fees associated with administration of the merger
activities.

     In August, 1996, the Company completed the acquisition of Interconnectix,
Inc. (Interconnectix), pursuant to a merger accounted for as a pooling of
interests. Accordingly, the results of Interconnectix are included in the
Company's Consolidated Financial Statements for all periods presented. A total
of 2,133 shares of the Company's common stock were issued in the transaction.
Merger expenses of $700 were incurred associated primarily with severance costs
and legal and accounting fees associated with administration of the merger
activities.

     In 1995, the Company completed five business combinations, two of which
were accounted for as pooling of interests and three of which were accounted for
as purchases. The Company purchased Axiom Datorer Scandinavian AB (Axiom), 3Soft
Corporation (3Soft), and Zeelan Technology, Inc. (Zeelan) in May 1995, December
1995, and December 1995, respectively. The purchase accounting allocations
resulted in charges for in-process R&D of $1,430, goodwill capitalization of
$528 and technology capitalization of $892.

     In October 1995, the Company acquired Precedence


                                                                              14
<PAGE>
Incorporated (Precedence), pursuant to a merger accounted for as a pooling of
interests. Accordingly, the results of Precedence are included in the Company's
Consolidated Financial Statements for all periods presented. A total of 735
shares of the Company's common stock were issued in the transaction. Merger
expenses of $210 were for services rendered to facilitate completion of the
merger agreement.

     In May 1995, the Company acquired Exemplar Logic, Inc. (Exemplar), pursuant
to a merger accounted for as a pooling of interests. Accordingly, the results of
Exemplar are included in the Company's Consolidated Financial Statements for all
periods presented. A total of 1,512 shares of the Company's common stock were
issued in the transaction. Merger expenses of $400 were for services rendered to
facilitate completion of the merger agreement and for severance costs.

     In 1994, the Company completed two business combinations, one of which was
accounted for as a pooling of interests and the other of which was accounted for
as a purchase. In September 1994, the Company completed the purchase of Anacad
Electrical Engineering Software GmbH (Anacad). The purchase accounting
allocation resulted in a charge for in-process R&D of $8,265, goodwill
capitalization of $2,897 and technology capitalization of $4,735.

     In November 1994, the Company acquired Model Technology Incorporated (MTI),
pursuant to a merger accounted for as a pooling of interests. A total of 2,443
shares of the Company's common stock were issued in the transaction. Merger
costs of $1,000 were paid by MTI for consulting services rendered to facilitate
negotiation of the various components of the merger agreement. Also, cash
distributions of $2,346 were paid in 1994 by MTI to its shareholders in the
normal course of S-Corporation business prior to the date of acquisition.

System and Software

     System and software revenues are derived from software products owned by
the Company, software products owned by third parties for which the Company pays
royalties, some workstation hardware and some accelerated verification system
sales as a result of the Meta acquisition in 1996. Software product revenues
accounted for approximately 85% of the 1996 increase in system and software
revenues, while a decline in workstation hardware product revenues was more than
offset by added accelerated verification system revenues. For 1995, software
product revenues increased by approximately 4%, while a decline in workstation
hardware product revenues partially offset this growth. The primary factor
contributing to the software product growth for 1996 and 1995 was increased
product offerings as a result of internal development and acquisitions over the
last several years. During 1996, the Company added new hardware/software
co-verification, re-usable intellectual property designs, library and data
management products and products that operate on Windows 95 and Windows NT
operating systems. The Company added many new products through business
combinations accounted for as purchases during 1996 and 1995, with such
purchases resulting in added revenues only from the date of acquisition and not
for all prior periods presented as is the case for pooling of interest
transactions.

     Revenues from the Company's older product offerings declined in 1996 and
1995, partially offsetting the volume increases of newer product offerings. In
the fourth quarter of 1996, revenues from product offerings introduced prior to
1993 were less than 50% of total revenues for the first time. The rate of
decline for these older product offerings is expected to continue to negatively
impact the Company's future software product revenue performance.

     Also, 1996 software product revenues have been adverse-


                                                                              15

ly affected by turnover of Microtec sales personnel.

     Sales in Japan were negatively affected by a strengthening of the U.S.
dollar as compared to the yen in 1996. In 1995 sales were positively affected by
a weakening of the U.S. dollar against the yen. See "Geographic Revenues
Information" below for further details of the effects of foreign currencies on
revenues.

     System and software gross margins as a percent of revenues declined from
1995 to 1996 due to higher costs for royalties related to third party contracts
and higher costs for amortization of previously capitalized software development
and purchased technology, offset by volume increases in system and software
revenues year to year. The Company continues to enter into and maintain third
party contracts that contribute varying levels of revenues and cost of revenues
quarter to quarter. Future trends of third party revenue content are difficult
to predict since they are dependent on such variables as new third party
agreements, potential acquisitions of third parties where existing agreements
are in place, and varying levels of customer demand for third party product
offerings.

     The improvement in gross margins from 1994 to 1995 was primarily a result
of increased software product versus workstation hardware sales year to year,
lower amortization cost for previously capitalized software development offset
by higher costs for amortization of purchased technology. Software product gross
margins are much higher than workstation hardware gross margins and the mix
shift in 1995 favorably impacted gross margins.

     Amortization of previously capitalized software development costs to system
and software cost of revenue was $6,215, $5,511, and $6,785 for 1996, 1995, and
1994, respectively. Amortization increased slightly in 1996 as the Company's
capitalization level increased in 1995 and to a lesser extent in 1994 as more
resources were directed to the development of new products and enhancement of
existing products. The 1995 decline in amortization is attributable to several
capitalized projects completing amortization schedules during 1994. Amortization
of purchased technology costs to system and software cost of revenues was
$3,559, $2,418 and $760 for 1996, 1995 and 1994, respectively. The increase in
1996 and 1995 is attributable to the purchase of seven and three companies in
1996 and 1995, respectively. Capitalized software development costs and
purchased technology costs are amortized over a three year period to system and
software cost of revenues. Due to the acquisitions previously discussed,
amortization of purchased technology is expected to continue to increase in
1997.

     Sales of accelerated verification systems, which are the result of the
Company's acquisition of Meta, are expected to have a negative impact on system
and software product gross margins over time. Meta products include hardware,
which does not yield gross margins as high as software product sales. The impact
of accelerated verification systems sales on system and software cost of
revenues and gross margins was offset by the decline in workstation hardware
revenues during 1996 compared to the same period last year. Sales volumes for
accelerated verification systems were not material to the Company's system and
software revenue levels in 1996.


Service and Support

     Service and support revenues consist of revenues from annual software
support maintenance contracts, hardware support, and professional services,
which includes consulting services, training services, and custom design
services. The increase in service and support revenues in 1996 is due primarily
to a 4% increase in software support revenues, partially offset by a 6% decline
in professional service revenues. The increase in service and support revenues
in 1995 is due to increases of 18% and 44% in software support and professional
service revenues, respectively.

     The 1996 decline in growth levels of software support is due in part to the
decline in revenues from the Company's older product offerings in 1996 resulting
in a slower rate of increase to the Company's installed base of customers and in
part to the unfavorable effects of foreign currency fluctuations discussed
below. Factors contributing to the growth in software support revenues in 1995
included the effect of increased software product sales in prior years, a
focused effort to increase the acceptance rate of the Company's software support
offerings and favorable effects of foreign currency fluctuations.


                                                                              16
<PAGE>
     The Company is currently unbundling maintenance services in response to
customer requests. This change will allow customers to choose varying levels of
phone support and software update support. The effect of this change may result
in lower revenue levels as some customers could choose less than full support
from available options. Since growth in software support is dependent on
continued success of the software product offerings, increases in the Company's
installed customer base, and the impact of acquisitions, future software support
revenue levels are difficult to predict.

     Professional service revenues totaled approximately $50,500, $53,800 and
$37,300 in 1996, 1995 and 1994, respectively. The decline in professional
service revenues in 1996 was attributable in part to a process of realigning the
core consulting business in an attempt to better support ASIC and IC design
methodologies. This realignment resulted in start-up difficulties such as proper
scoping of personnel requirements to meet engagement deliverables and recruiting
and hiring of additional personnel qualified to meet such deliverables, all of
which delayed conversion of order backlog into revenue. This decline was
partially offset by increased custom design professional service revenues as
customer demand for such services continued to grow. The increase in 1995 was
primarily attributable to strong demand for both consulting services and custom
design services.

     Service and support gross margins decreased in 1996 as a result of negative
professional service gross margins, partially offset by slightly improved
software support gross margins. The negative professional service gross margins
are the result of the start-up difficulties discussed above and unexpected costs
to complete certain custom design contracts. Service and support gross margins
improved in 1995 as a result of higher software maintenance revenues volume and
slightly improved professional service gross margins.

     Consistent with EDA consulting and training business models, gross margins
generated by the Company's professional service activities have been, and are
expected to continue to be, lower than software support. As a result, service
and support gross margins may continue to decline as growth in the professional
service business is expected to be higher than growth in software support.


Geographic Revenues Information

     Domestic revenues from unaffiliated customers including service and support
revenues increased by 7% from 1995 to 1996 and 7% from 1994 to 1995.
International revenues from unaffiliated customers including service and support
revenues represented 46%, 48% and 46% of total revenues in 1996, 1995 and 1994,
respectively. European revenues decreased by 3% from 1995 to 1996 and increased
by 17% from 1994 to 1995. Japanese revenues decreased by 1% from 1995 to 1996
and increased by 11% from 1994 to 1995. The effects of exchange rate differences
from the Japanese Yen to the U.S. dollar negatively impacted revenues by
approximately 14% in 1996 and positively impacted revenues by approximately 7%
in 1995. The effects of exchange rate differences from European currencies to
the U.S. dollar for 1996 and 1995 were not significant as approximately half of
European revenues are booked in U.S. dollars and movements of such currencies
against the U.S. dollar were not significant. For 1996, European revenues were
unfavorably impacted by a slowdown in spending by telecommunication customers
while Japanese revenues were favorably impacted by new product offerings
previously discussed. For 1995, European revenues were favorably impacted by
improving economic conditions while Japan's results reflected economic weakness.
Since the Company generates approximately half of its revenues outside of the
United States and expects this to continue in the future, revenue results should
continue to be impacted by the effects of future foreign currency fluctuations.

Research and Development

     As a percent of revenue, gross R&D costs were approximately flat from 1995
to 1996 and decreased slightly from 1994 to 1995. In 1996, gross R&D costs
increased due, in part, to the purchases of 3Soft late in 1995 and Seto and Meta
in 1996, which resulted in a year to year increase of approximately $5,000. In
1995, gross R&D costs increased due to the purchases of Anacad and Axiom, which
resulted in a year to year increase of approximately $4,000. In addition, other
business combinations accounted for as pooling of interests including Microtec,
MTI, Exemplar, Precedence and Interconnectix, which were included in 1996 and
1995 results, experienced higher R&D investment in 1996 and 1995. Offsetting
these increases, was a reduction in spending for base business product lines.
During 1996, the Company capitalized software development costs of $5,691,
compared to $8,129 and $5,718 for 1995 and 1994, respectively.

     The Company will continue to evaluate make-versus-buy alternatives in 1997
which may result in more acquisitions. Overall, management's goal, which may not
be acheived, is to maintain or reduce the ratio of R&D expense as a percent of
revenues from 1996 levels. Achievement of this goal is not guaranteed. See
"Factors That May Affect Future Results and Financial Condition" discussion
below.


Marketing and Selling

     In 1996 and 1995, the increase in marketing and selling expenses was
principally attributable to merger and acquisition activity discussed above and
revenue growth year to year. The year to year impact of acquisitions on
marketing and selling costs in 1996 was approximately $6,000. In addition, the
Company incurred higher selling costs due to higher revenue levels year to year
and higher marketing costs due to increased new product introductions. In 1995,
marketing and selling expenses increased due to the purchases of Anacad and
Axiom which resulted in a year to year increase of approximately $3,700. A
stronger U.S. dollar during 1996 reduced expenses by approximately 7% and 19% in
Europe and Japan, respectively. For 1995, a weaker U.S. dollar increased
expenses by approximately 3% and 17% in Europe and Japan, respectively.

General and Administrative

     The increase in general and administrative costs from 1995 to 1996 was a
result of integration costs and additional headcount related to business
purchases previously discussed. For 1995, the decrease from 1994 was due to a
focused effort to reduce administrative expenses during the year.


Special Charges

     In the fourth quarter of 1996, the Company recorded special charges of
$11,998. The Company downsized and redirected certain operations and retargeted
an incentive compensation program resulting in severance costs, facility lease
and equipment abandonment costs and other costs totaling approximately $7,000.
The Company also recognized an impairment in value of goodwill and certain other
assets associated with its Meta subsidiary which resulted in a write-down of
$5,000. During 1995, the Company filed suit in United States (U.S.) Federal
District Court against Quickturn Design Systems, Inc. (competitor) for
declarative judgment on non-infringement, invalidity and unenforceability of
three of the competitor's patents in anticipation of acquiring Meta. In January
1996, the competitor filed an administrative complaint with the International
Trade Commission (ITC), a federal administrative agency, seeking to hinder the
distribution of the Meta technology in the United States. Early in the third


                                                                              18
<PAGE>
quarter of 1996, the ITC issued a temporary ruling allowing the importation of
this technology to the U.S., but requiring posting of a bond for each sale.
Subsequent to the ITC temporary ruling, domestic orders for Meta products were
not as strong as expected. While the Company continues to expect the Meta
technologies to perform favorably over a longer term, the near-term outlook is
not positive enough to support reasonable recoverability of the carrying amounts
of these assets.

     During the second quarter of 1995, the Company recorded a $2,040 special
charge adjustment. The adjustment was primarily associated with the 1993 charge
and was mainly the result of reduced estimates for severance costs associated
with replacement and globalization of the Company's information systems.
Information system implementation delays culminated when a key project plan
milestone was missed during the second quarter, resulting in lower estimated
costs for write-offs of old equipment due to prolonged in-service periods. In
addition, certain actions associated with a product discontinuance plan were not
taken when management determined that the technology could be used by the
Company's consulting organization and sold as a custom integrated service rather
than as a commercial design tool.

     During 1994, the Company recorded a special charge credit of $10,045 offset
by an accrual of $4,000. The credit was primarily associated with the 1993 and
to a lesser extent the 1992 special charges and was the result of reduced
estimates for severance costs due to greater than anticipated employee attrition
among the product development and field selling organizations and lower costs of
executing the plan. In the third quarter of 1994 the Company lowered its
estimate of the cost of the 1993 plan by $5,600 mainly as a result of lower than
anticipated costs associated with completion of the first phase of the Company's
Japanese subsidiary re-alignment. Estimated costs of executing the plan were
lowered by an additional $4,445 in the fourth quarter of 1994 due to several
changes in circumstances. In the third and fourth quarters of 1994, the Company
exceeded its goal for reducing operating expenses, exclusive of recent
acquisitions. In addition, senior management changes subsequent to the initial
1993 charge resulted in re-evaluating and revising certain planned actions, such
as the relocation of European headquarters and the out-sourcing of European
order fulfillment. These elements of the plan were revised because lower head
count through attrition and efficiencies through centralization made them
financially less attractive. In the fourth quarter of 1994, an additional
accrual of $4,000 was established primarily to reduce a recently acquired
subsidiary's engineering staff and management team and to further streamline the
Company's core product development activities, including elimination of certain
product offerings and reductions in engineering staff.

     All of the $3,751 special charge accrual as of December 31, 1995 resulted
in cash outflows in 1996. The remaining accrual of $5,340 as of December 31,
1996 is expected to be disbursed in 1997.


Merger and Acquisition Related Charges

     In 1996, the Company incurred merger and acquisition related charges of
$31,344 as a result of nine business combinations. Seven acquisitions were
accounted for as purchases which resulted in charges for in-process R&D of
$26,234. The charges were a result of allocating a portion of the acquisition
costs to in-process product development that had not reached technological
feasibility. The acquisitions of Microtec and Interconnectix were accounted for
as pooling of interests which resulted in merger expenses of $4,410 and $700,
respectively. These costs were for services rendered to facilitate completion of
the merger agreements, severance costs to eliminate redundant management
positions and facilities closure costs to eliminate redundant sales offices.

     In 1995 the Company incurred merger related charges of $2,040. The
purchases of Axiom, 3Soft and Zeelan resulted in charges for in-process R&D of
$400, $850, and $180, respectively. The acquisitions of Precedence and Exemplar
were accounted for as pooling of interests which resulted in merger expenses of
$400 and $210, respectively. These costs were for services rendered to
facilitate completion of the merger agreements and severance costs to eliminate
redundant management positions.

     In 1994 the Company incurred acquisition related charges of $9,265. The
purchase of Anacad resulted in a charge for in-process R&D of $8,265. In
addition, merger expenses of $1,000 were paid by MTI for consulting services
rendered to facilitate negotiation of the various components of the merger
agreement.


                                                                              19

Other Income (Expense)

Year ended December 31,                 1996           1995            1994
- ---------------------------------------------------------------------------
Other income, net                  $   8,411       $  6,494       $   3,238
- ---------------------------------------------------------------------------


     Interest income was $9,485, $9,194, and $5,247 in 1996, 1995 and 1994,
respectively. The improvement in interest income is attributable to higher
average cash balances due to earnings in 1995 and 1994. Interest expense was
$2,423, $2,585, and $2,826 in 1996, 1995 and 1994, respectively. In 1996, the
Company sold common stock of two independent public companies for $6,744 which
had carrying costs of $1,199, resulting in a gain of $5,545. Other income was
adversely affected by legal costs related to the litigation with a competitor of
$3,611 in 1996.


Provision for Income Taxes

     The provision for income taxes was $3,540, $8,542 and $3,765 in 1996, 1995
and 1994, respectively. The $3,540 tax provision in 1996 despite a $1,438
pre-tax loss for the year is primarily due to one-time non-tax deductible in
process R&D charges and other non-tax deductible costs related to acquisitions.
These increases to the tax provision were partially offset due to the reversal
of the valuation allowance for certain current deferred tax assets and due to
significant pre-tax income in certain jurisdictions where lower tax rates apply.
Based on the Company's operating income levels before tax in the United States
(U.S.), it was determined that it was more likely than not that certain of its
current deferred tax assets in the U.S. would be realized. As such, the tax
provision for 1996 was reduced for the reversal of the valuation allowance for
those deferred tax assets.

     The Company incurred a lower effective tax rate in 1995 compared to 1994
primarily due to the reversal of the valuation allowance related to deferred tax
assets of the Company's Japanese subsidiary. Based on operating income levels
before tax for this subsidiary, it was determined that it was more likely than
not that its deferred tax assets would be realized. As such, the tax provision
for 1995 was reduced for the reversal of the valuation allowance for the
Japanese deferred tax assets.

     The Company's income tax position for each year combines the effects of
available tax benefits in certain countries where the Company does business,
benefits from available net operating loss carry forwards, and tax expense for
subsidiaries with pre-tax income. As such, the Company's income tax position and
resultant effective tax rate is uncertain for 1997 and beyond.


Effects of Foreign Currency Fluctuations

     Approximately half of the Company's revenues are generated outside of the
United States. For 1996 and 1995, approximately half of European and all of
Japanese revenues were subject to exchange rate fluctuations as they were booked
in local currencies. The effects of these fluctuations were substantially offset
by local currency cost of revenues and operating expenses resulting in an
immaterial net effect on the Company's results of operations.

     The "foreign currency translation adjustment," as reported in the
stockholders' equity section of the consolidated balance sheets, decreased to
$12,098 at December 31, 1996, from $13,594 at the end of 1995. This reflects the
decrease in the value of net assets denominated in foreign currencies since
year-end 1995 as a result of a stronger U.S. dollar at the close of 1996.

     During 1995, the Company entered into a three year forward contract to
stabilize the currency effects on a portion of the Company's net investment in
its Japanese subsidiary. The contract to sell Yen 2.2 billion will guarantee the
Company $24,900 at the contract's expiration. Any differences between the
contracted currency rate and the currency rate at each balance sheet date will
impact the foreign currency translation adjustment component of the
stockholders' equity section of the consolidated balance sheet. The result is a
partial offset of the effect of Japanese currency changes on stockholders'
equity during the contract term. This forward contract should not impact current
or future consolidated statements of operations.

Cash and Investments

     Total cash and investments decreased $14,917 during 1996. Cash provided by
operations was $42,314, a decrease of $39,939 from 1995. A net loss of $4,978
negatively impacted cash provided by operations in 1996. In addition, the
Company completed nine business combinations, six of which required cash
payments of $32,358. In 1995, cash was positively impacted by the net profit
earned of $50,506 for the year. This source of cash was offset by an increase in
trade accounts receivables and a decrease in accrued liabilities associated with
the special charges accrual.

     Cash and short-term investments were positively impacted by the proceeds
from issuance of common stock upon exercise of stock options and employee stock
plan purchases in the amount of $12,477 and $17,429 in 1996 and 1995,
respectively. This increase was offset by investment in property, plant and
equipment of $23,931 in 1996 and $22,653 in 1995 and repurchases of common stock
of $11,507 in 1996 and $2,250 in 1995.


Trade Accounts Receivable

     The trade accounts receivable balance increased $11,995 from December 31,
1995. The increase is primarily attributable to an increase in shipments late in
the quarter versus a more evenly distributed shipment pattern. The Company has
historically realized a majority of revenues in the last month of each quarter
due to the timing of orders and experienced an increase in this trend in 1996.
Future trade receivable trends are difficult to predict due to this
relationship.

Other Assets

     Other assets increased to $42,914 at December 31, 1996 from $38,184 at
December 31, 1995. Net capitalized software development costs decreased by $524
in 1996. Seven acquisitions accounted for as purchases in 1996 resulted in
goodwill capitalization of $5,517 and technology capitalization of $8,957,
partially offset by amortization of $6,998 and a goodwill write-down of $2,747.
In addition, the Company sold common stock of two independent public companies
in 1996. In 1995, net capitalized software development costs increased by
$2,618. Three acquisitions accounted for as purchases in 1995 resulted in
goodwill capitalization of $528 and technology capitalization of $892. Goodwill
costs are being amortized over a three year period to R&D expense and technology
costs are being amortized over a three year period to system and software cost
of revenues.


Long-term Debt

     Long-term debt decreased $501 from December 31, 1995. The Company had total
borrowings outstanding of $52,480 and $53,320 under its $55,000 committed
revolving credit facility as of December 31, 1996 and 1995, respectively. As of
December 31, 1996, the Company maintained an interest rate swap agreement
associated with the revolving credit facility debt which effectively converts
floating rates on $17,500 of the debt to a fixed rate of 9.55%. Effective
February 11, 1997, the Company terminated its interest rate swap agreement at a
cost of $1,650. In addition, in the first quarter of 1997, the Company approved
a plan to pay down the committed revolving credit facility to


                                                                              21
<PAGE>
zero by the end of the March 1997. The Company expects to use its cash and short
term investments and its long-term cash to complete this pay-down.

Capital Resources

     Total capital expenditures increased to $58,872 for 1996, compared to
$30,313 for 1995. Nine business combinations were completed in 1996, of which
six resulted in cash payments of $32,358. The Company also acquired a number of
technologies, primarily software source code, totaling $2,583 in 1996. In
addition, the Company purchased technologies totaling $1,444 during 1995. The
Company will continue to evaluate make-versus-buy alternatives which should
result in additional capital expenditures in 1997. Expenditures for property and
equipment were $23,931 and $22,653 in 1996 and 1995, respectively. Future
capital expenditure plans include maintaining current design environment
equipment and sales demonstration equipment and continuing the implementation of
a new global information system.

     The Company anticipates that current cash balances, anticipated cash flows
from operating activities, and existing credit facilities will be sufficient to
meet its working capital needs for at least the next twelve months.

Factors That May Affect Future Results And
Financial Condition

     The statements contained in this annual report that are not statements of
historical fact are forward looking statements that involve a number of risks
and uncertainties. Moreover, from time to time the Company may issue other
forward looking statements. The following discussion highlights factors that
could cause actual results to differ materially from the forward looking
statements. The forward looking statements should be considered in light of
these factors.

     The Company competes in the highly competitive and dynamic EDA (electronic
design automation) and integrated systems design industries. The Company's
success is dependent upon its ability to develop and market products that are
innovative, cost-competitive and that meet customers' expectations, and to
deliver those products to its customers in a timely manner. Competition in the
EDA industry is intense, which can create adverse effects including, but not
limited to, price reductions, lower product margins, loss of market share and
additional working capital requirements.

     A material amount of the Company's software product revenue is usually the
result of current quarter order performance of which the majority is usually
booked in the last month of each quarter. In addition, the Company's revenue
often includes multi-million dollar contracts. The timing of the completion of
these contracts and the terms of delivery of software, hardware and other
services can have a material impact on revenue recognition for a given quarter.
The combination of these factors impairs and delays the Company's ability to
identify shortfalls or overages from quarterly revenue targets.

     The Company generally realizes approximately half of its revenues outside
the United States and expects this to continue in the future. As such, the
Company's business and operating results can be impacted by the effects of
foreign currency fluctuations. In order to hedge the impact of foreign currency
fluctuations, the Company enters into foreign currency forward contracts.
However, significant changes in exchange rates may have a material adverse
impact on the Company's results of operations. International operations subject
the Company to other risks including, but not limited to, changes in regional or
worldwide economic or political conditions, government trade restrictions,
limitations on repatriation of earnings, licensing and intellectual property
rights protection.

     The Company is currently reorganizing its professional services business to
better support its integrated systems design strategy which focuses on ASIC and
IC design methodologies. This resulted in lower billable hours for revenue
generating services in 1996. In addition, business reorganizations can increase
personnel management complexities including retention and hiring of key
technical and management positions. While the Company will look to improve the
utilization of its consultants, there can be no assurance that the challenges
will be effectively met.

     The Company's operating expenses are generally committed in advance of
revenue and are based to a large degree on future revenue expectations.
Operating expenses are incurred in order to generate and sustain higher future
revenue levels. If the revenue does not materialize as expected, the Company's
results of operations can be adversely impacted.

     Acquisitions of complementary businesses are an integral part of the
Company's overall business strategy. There are several risks associated with
this strategy including integration of sales channels, training and education of
the sales force for new product offerings, integration of product development
efforts, retention of key employees, integration of systems of internal
controls, and integration of information systems. All of these factors can
impair the Company's ability to forecast, to meet quarterly revenue and earnings
targets, and to effectively manage the business for long-term growth.


                                                                              22
<PAGE>
While the Company is aware of and is addressing such issues, there can be no
assurance that these challenges will be effectively met.

     As a result of the acquisition of Meta, the Company has entered the
hardware development and assembly business. Some additional issues must be
managed by the Company, such as: procuring hardware components on a timely
basis, assembling and shipping systems on a timely basis with appropriate
quality control, developing new distribution and shipment processes, managing
inventory and placing new demands on the sales force.

     The Company has recently added new re-usable intellectual property products
and services to its portfolio of offerings to address this emerging market. As
with all emerging markets, there is inherent uncertainty regarding the overall
rate of growth. Specifically, growth in the re-usable intellectual property
market is subject to significant uncertainties and risks as market participants,
including the Company, seek to gain customer acceptance for the overall concept
of incorporating these intellectual property designs into their products,
identify and develop the correct products to meet evolving customer demands, and
identify and implement effective distribution models for this new class of
products.

     The Company is currently involved in the replacement of its financial
information systems, based primarily on software from SAP. The implementation
phase of new information systems can cause significant disruptions to the
Company's work efficiency. There can be no assurance that the project will be
completed within budgeted time or dollar parameters.

     The Company believes it has been successful at recruiting and retaining
necessary personnel to research and develop products that satisfy customers
needs. There can be no assurance that the Company can continue to recruit and
retain such personnel.

     Generally accepted accounting principles require management to make
estimates and assumptions that affect the reported amounts of assets,
liabilities and contingencies at the date of the financial statements and the
reported amounts of revenue and expenses during the reporting periods. Actual
results could differ from those estimates.

     Due to the factors above, as well as other market factors outside the
Company's control, the Company's future earnings and stock price may be subject
to significant volatility. Past financial performance should not be considered a
reliable indication of future performance. The investment community should use
caution in using historical trends to estimate future results or trends. In
addition, if future results vary significantly from expectations of analysts,
the Company's stock price could be adversely impacted.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

All numerical references in thousands, except percentages and per share data

1.   Summary of Significant Accounting Policies

Principles of Consolidation

     The consolidated financial statements include the financial statements of
the Company and its wholly owned and majority-owned subsidiaries. All
significant intercompany accounts and transactions are eliminated in
consolidation.

Foreign Currency Translation

     Local currencies are the functional currencies for the Company's foreign
subsidiaries except for the Netherlands and Singapore where the U.S. dollar is
used as the functional currency. Assets and liabilities of foreign operations
are translated to U.S. dollars at current rates of exchange, and revenues and
expenses are translated using weighted average rates. Gains and losses from
foreign currency translation are included as a separate component of
stockholders' equity. Foreign currency transaction gains and losses are included
as a component of other income and expense.

Financial Instruments

     The Company enters into forward foreign exchange contracts as a hedge
against foreign currency sales commitments. To hedge its foreign currency
against highly anticipated sales transactions, the Company also purchases
foreign exchange options which permit but do not require foreign currency
exchanges at a future date with another party at a contracted exchange price.
Remeasurement gains and losses on forward and option contracts are deferred and
recognized when the sale occurs. All subsequent remeasurement gains and losses
are recognized as they occur to offset remeasurement gains and losses recognized
on the related foreign currency accounts receivable balances. At December 31,
1996 and 1995, the Company had forward contracts and options outstanding of
$39,058 and $38,069, respectively, to primarily sell various foreign currencies.
These contracts generally have maturities which do not exceed twelve months. At
December 31, 1996 and 1995, the difference between the recorded value and the
fair value of the Company's foreign exchange position related to these contracts
was approximately zero. The fair value of these contracts was calculated based
on dealer quotes. The Company does not anticipate non-performance by the
counterparties to these contracts.

     During 1995, the Company entered into a three year forward contract to
stabilize the currency effects on a portion of the Company's net investment in
its Japanese subsidiary. The contract was amended in 1996, reducing some
portions to a shorter term. The revised contract to sell Yen 2.2 billion will
guarantee the Company $24,900 at the contract's expiration. Any differences
between the contracted currency rate and the currency rate at each balance sheet
date will impact the foreign currency translation adjustment component of the
stockholders' equity section of the Consolidated Balance Sheets. The result is a
partial offset of the effect of Japanese currency changes on stockholders'
equity during the contract term. This forward contract should not impact current
or future consolidated statements of operations. At December 31, 1996, the
difference between the recorded value and the fair value of the Company's
foreign exchange position related to this contract was approximately zero. The
fair value of this contract was calculated based on dealer quotes. The Company
does not anticipate non-performance by the counterparty to this contract.

     The fair market value of the Company's long-term debt approximates its
carrying value as the interest rates on borrowings are floating rate based. The
Company has entered into an interest rate swap agreement to manage exposure to
interest rate fluctuations. The differential to be paid or received is accrued
and is recognized over the life of the agreement as an adjustment to interest
expense.

     The Company places its cash equivalents and short-term investments with
major banks and financial institutions. The Company's investment policy limits
its credit exposure to any one financial institution. Concentrations of credit
risk with respect to trade receivables are limited due to the large number of
customers comprising the Company's customer base, and their dispersion across
different businesses and geographic areas. The carrying amounts of cash
equivalents, short-term investments, trade receivables, accounts payable, and
short term borrowings approximate fair value because of the short-term nature of
these instruments.

     Statement of Financial Accounting Standards No. 115, "Accounting for
Certain Investments in Debt and Equity Securities" requires reporting of
investments as either held to maturity, available for sale or trading. Under
Statement No. 115, the securities held had been classified as available for
sale, which requires the difference between original carrying cost and market
value to be recognized as a separate component of stockholders' equity.

Cash, Cash Equivalents, and Short-Term Investments

     The Company classifies highly liquid investments purchased with an original
maturity of three months or less as cash equivalents. As of December 31, 1996
and 1995, the Company held $41,211 and $41,716, of short term securities under
agreements to resell on January 1, 1997 and 1996, respectively. Due to the
short-term nature of these investments,


                                                                              28
<PAGE>
the Company did not take possession of the securities. The Company does not
believe it is exposed to any significant credit risk or market risk on cash and
cash equivalent balances.

     Short-term investments consist of certificates of deposit, commercial paper
and other highly liquid investments with original maturities in excess of three
months. These investments mature primarily in less than one year.

Property, Plant and Equipment

     Property, plant and equipment is stated at cost and consists of land and
land improvements, buildings and building equipment, computer equipment,
information systems and furniture, leasehold improvements, and service spare
parts. Expenditures for additions to property, plant and equipment are
capitalized. The cost of repairs and maintenance is expensed as incurred.
Depreciation of buildings and building equipment, and land improvements, is
computed on a straight-line basis over lives of forty and twenty years,
respectively. Depreciation of computer equipment and furniture is computed
principally on a straight-line basis over the estimated useful lives of the
assets, generally three to five years. Leasehold improvements are amortized on a
straight-line basis over the lesser of the term of the lease or estimated useful
lives of the improvements. Service spare parts are amortized on a straight-line
basis over their estimated useful lives, generally four years.

     Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of." Statement No. 121 provides
specific guidance regarding when impairment of long-lived assets such as plant,
equipment and certain intangibles including goodwill and capitalized technology
should be recognized and how impairment losses of such assets should be
measured. Initial adoption of Statement No. 121 did not have a material effect
on the Company's consolidated financial statements. Management reviews
long-lived assets and the related intangible assets for impairment whenever
events or changes in circumstances indicate the carrying amount of such assets
may not be recoverable. Recoverability of these assets is determined by
comparing the forecasted undiscounted net cash flows of the operation to which
the assets relate, to the carrying amount including associated intangible assets
of such operation. If the operation is determined to be unable to recover the
carrying amount of its assets, then intangible assets are written down first,
followed by the other long-lived assets of the operation, to fair value. Fair
value is determined based on discounted cash flows or appraised values,
depending upon the nature of the assets.

Income Taxes

     The Company uses the asset and liability method of accounting for income
taxes. Under the asset and liability method, deferred income taxes are
recognized for the future tax consequences attributable to temporary differences
between the financial statement carrying amounts and tax balances of existing
assets and liabilities. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. The effect
on deferred taxes of a change in tax rates is recognized in income in the period
that includes the enactment date.

Revenue Recognition

     Revenues from system sales and software licenses are recognized at the time
of shipment. Contract service revenues are billed in advance and recorded as
deferred revenue. Service revenues are then recognized ratably over the
contractual period as the services are performed. Training and consulting
revenues are recognized as the related services are performed. Custom design and
software porting revenues are recognized using the percentage of completion
method or as contract milestones are achieved.

Software Development Costs

     The Company accounts for software development costs in accordance with
Statement of Financial Accounting Standards No. 86, "Accounting for the Costs of
Computer Software to be Sold, Leased or Otherwise Marketed." The Company
capitalizes certain costs incurred in the production of computer software once
technological feasibility of the product to be marketed has been established.
Capitalization of these costs ceases when the product is considered available
for general release to customers. Costs incurred prior to technological
feasibility, including amounts attributable to in-process research and
development in business acquisitions, are expensed as incurred.

     Amortization of capitalized software development costs is calculated as the
greater of the ratio that the current product revenues bear to estimated future
revenues or the straight-line method over the expected product life cycle of
approximately three years. Amortization is included in system and software cost
of revenues in the Consolidated Statements of Operations.

Stockholders' Equity

     In August 1995, the Company's Board of Directors approved a plan to
repurchase, from time to time over the next eighteen months on the open market,
up to $50,000 in market value of the Company's common shares. During 1996, the
Company repurchased 833 shares, approximately 500 of 


                                                                              29
<PAGE>
which were repurchased immediately prior to Employee Stock Purchase Plan
purchases and then reissued to the plan participants. The remaining shares were
repurchased in the first quarter of 1996 and subsequently reissued through stock
option exercises prior to consummation of the August 1996 acquisition of
Interconnectix, Inc. The market value of all shares repurchased in 1996 was
$11,507. In the third quarter of 1996, the Company's Board of Directors
rescinded the share repurchase plan except that the Board authorized the
continued repurchase of shares for purposes of immediate reissuance under the
Employee Stock Purchase Plan.

     During the third quarter of 1995, the Company repurchased 110 shares on the
open market with a market value of $2,250. These shares were subsequently
reissued through the stock option exercises prior to consummation of the October
1995 acquisition of Precedence Incorporated.

Net Income (Loss) per Common and Common
Equivalent Share

     For 1996, net loss per common and common equivalent share was calculated
using only the weighted average of common shares outstanding. Common stock
equivalents related to stock options are anti-dilutive in a net loss situation
and, therefore, were not included in 1996. For 1995 and 1994, net income per
common and common equivalent share was calculated on the basis of the weighted
average number of common shares outstanding plus dilutive common stock
equivalents related to stock options outstanding.

Use of Estimates

     Generally accepted accounting principles require management to make
estimates and assumptions that affect the reported amount of assets, liabilities
and contingencies at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting periods. Actual results
could differ from those estimates.

Reclassifications and Restatements

     Certain reclassifications have been made in the accompanying consolidated
financial statements for 1994 and 1995 to conform with the 1996 presentation. As
discussed in Note 3, certain acquisitions have resulted in the Company's
restatement of its consolidated financial statements.

2.   Special Charges

Following is a summary of the major elements of the special charges:

</TABLE>


     In the fourth quarter of 1996, the Company recorded special charges of
$11,998. The Company downsized and redirected certain operations and retargeted
an incentive compensation program resulting in severance costs, facility lease
and equipment abandonment costs and other costs totaling approximately $7,000.
The Company also recognized an impairment in value of goodwill and certain other
assets associated with its Meta subsidiary which resulted in a write-down of
$5,000. During 1995, the Company filed suit in United States (U.S.) Federal
District Court against Quickturn Design Systems, Inc. (competitor) for
declarative judgment on non-infringement, invalidity and unenforceability of
three of the competitor's patents in anticipation of acquiring Meta. In January
1996, the competitor filed an administrative complaint with the International
Trade Commission (ITC), a federal administrative agency, seeking to hinder the
distribution of the Meta technology in the United States. Early in the third
quarter of 1996, the ITC issued a temporary ruling allowing the importation of
this technology to the U.S., but requiring posting of a bond for each sale.
Subsequent to the ITC temporary ruling, domestic orders for Meta products were
not as strong as expected. While the Company continues to expect the Meta
technologies to perform favorably over a longer term, the near-term outlook is
not positive enough to support reasonable recoverability of the carrying amounts
of these assets.

     During the second quarter of 1995, the Company recorded a $2,040 special
charge adjustment. The adjustment was primarily associated with the 1993 charge
and was mainly the 


                                                                              30
<PAGE>
result of reduced estimates for severance costs associated with replacement and
globalization of the Company's information systems. Information system
implementation delays culminated when a key project plan milestone was missed
during the second quarter, resulting in lower estimated costs for write-offs of
old equipment due to prolonged in-service periods. In addition, certain actions
associated with a product discontinuance plan were not taken when management
determined that the technology could be used by the Company's consulting
organization and sold as a custom integrated service rather than as a commercial
design tool.

     During 1994, the Company recorded a special charge credit of $10,045 offset
by an accrual of $4,000. The credit was primarily associated with the 1993 and
to a lesser extent the 1992 special charges and was the result of reduced
estimates for severance costs due to greater than anticipated employee attrition
among the product development and field selling organizations and lower costs of
executing the plan. In the third quarter of 1994 the Company lowered its
estimate of the cost of the 1993 plan by $5,600 mainly as a result of lower than
anticipated costs associated with completion of the first phase of the Company's
Japanese subsidiary re-alignment. Estimated costs of executing the plan were
lowered by an additional $4,445 in the fourth quarter of 1994 due to several
changes in circumstances. In the third and fourth quarters of 1994, the Company
exceeded its goal for reducing operating expenses, exclusive of recent
acquisitions. In addition, senior management changes subsequent to the initial
1993 charge resulted in re-evaluating and revising certain planned actions, such
as the relocation of European headquarters and the out-sourcing of European
order fulfillment. These elements of the plan were revised because lower head
count through attrition and efficiencies through centralization made them
financially less attractive. In the fourth quarter of 1994, an additional
accrual of $4,000 was established primarily to reduce a recently acquired
subsidiary's engineering staff and management team and to further streamline the
Company's core product development activities, including elimination of certain
product offerings and reductions in engineering staff.

     All of the $3,751 special charge accrual as of December 31, 1995 resulted
in cash outflows in 1996. The remaining accrual of $5,340 as of December 31,
1996 is expected to be disbursed in 1997.

3.   Business Acquisitions

     In 1996, the Company completed nine business combinations: two were
accounted for as pooling of interests and seven were accounted for as purchases.
The Company purchased dQdt, Inc. (dQdt), Meta Systems (Meta), Seto Software Gmbh
(Seto), Royal Digital Centers, Inc. (Royal Digital), Open Networks Engineering
Inc. (ONE), Systolic Technology, LTD (Systolic), and CAE Technology, Inc. (CAE)
in April 1996, May 1996, June 1996, August 1996, November 1996, November 1996
and December 1996, respectively. The results of operations of each acquisition
accounted for as a purchase are included in the Company's results of operations
from the date of acquisition. dQdt is primarily engaged in developing and
marketing intellectual property (IP) related to advanced digital signal
processor design for communication and multimedia applications. Meta is
primarily engaged in developing and marketing accelerated verification products.
Seto is primarily engaged in developing and marketing personal computer-based
layout tools used in the printed circuit board design process. Royal Digital is
primarily engaged in developing and marketing printed circuit board
computer-aided design tools that enhance design-for-manufacturability. ONE is

and computer peripheral interfaces.

     The total purchase price including acquisition expenses for all 1996
purchase acquisitions was $40,708. The Company paid the purchase price in cash
for each transaction except for dQdt in which the Company paid the purchase
price in its common stock with a market value on the purchase date of $1,825.
The cost of each acquisition was allocated on the basis of estimated fair value
of the assets and liabilities assumed. In connection with all purchase
acquisitions, the Company recorded one-time charges to operations for the
write-off of each enterprises' in-process product development that had not
reached technological feasibility. The purchase accounting allocations resulted
in charges for in-process R&D of $26,234, goodwill capitalization of $5,517, and
technology capitalization of $8,957. The separate operational results of all
acquisitions accounted for as purchases were not material compared to the
Company's overall results of operations, and accordingly pro-forma financial
statements of the combined entities have been omitted.

     On January 31, 1996, the Company issued 6,223 shares of its common stock
for all outstanding common stock of Microtec Research, Inc. (Microtec). In
addition, the Company reserved 688 shares of its common stock for previously
outstanding options to purchase Microtec common stock. These options vest and
become exercisable under the

<PAGE>
terms of the respective, original Microtec stock option agreements. The Company
accounted for this transaction as a pooling of interests and accordingly, the
Company's consolidated financial statements have been restated to include the
results of Microtec for all periods presented. Microtec is primarily engaged in
developing and marketing embedded systems and products to optimize the
development and operation of embedded systems across hardware/software
boundaries. Merger expenses of $4,410 were incurred associated with the
elimination of duplicate facilities, severance costs, the write-off of certain
property and equipment and legal and accounting fees associated with
administration of the merger.

     On August 30, 1996, the Company issued 2,133 shares of its common stock for
all outstanding common stock of Interconnectix, Inc. (Interconnectix). In
addition, the Company reserved 112 shares of its common stock for previously
outstanding options to purchase Interconnectix common stock. These options vest
and become exercisable under the terms of the respective, original
Interconnectix stock option agreements. The Company accounted for this
transaction as a pooling of interests and accordingly, the Company's
consolidated financial statements have been restated to include the results of
Interconnectix for all periods presented. Interconnectix is primarily engaged in
developing and marketing interconnect synthesis software for the design of
high-speed, high-performance printed circuit boards. Merger expenses of $700
were incurred associated with severance costs and legal and accounting fees

standard logic functions or blocks which are process technology independent. The
purchase accounting allocations resulted in charges for in-process R&D of
$1,430, goodwill capitalization of $528 and technology capitalization of $892.

     In May 1995, the Company issued 1,512 shares of its common stock for all
outstanding common stock of Exemplar Logic, Inc. (Exemplar). Exemplar develops,
markets and supports a family of software tools for high level design automation
for the application specific integrated circuit and field programmable gate
array markets. The Company accounted for this transaction as a pooling of
interests and accordingly, the results of Exemplar are included in the Company's
consolidated financial statements for all periods presented. Merger expenses of
$400 were for services rendered to facilitate completion of the merger agreement
and severance costs.

     In October 1995, the Company issued 735 shares of its common stock for all
outstanding common stock of Precedence Incorporated (Precedence). Precedence is
primarily engaged in developing, marketing and supporting simulation backplane

and the issuance of a short-term obligation classified under accrued liabilities
totaling $1,950, which was fully paid by December 31, 1995. The purchase
accounting allocation resulted in a charge for in-process R&D of $8,265,
goodwill capitalization of $2,897 and technology capitalization of $4,735.

     In December 1994, the Company issued 2,443 shares of its common stock for
all outstanding common stock of Model Technology Incorporated (MTI). MTI is a
developer of VHDL and Verilog simulation point tools using direct compile
technology to design and test components and boards. The Company accounted for
this transaction as a pooling of interests and accordingly, the results of MTI
are included in the Company's consolidated financial statements for 1994 and
1995. Merger costs of $1,000 were paid by MTI for consulting services rendered
to facilitate negotiation of the various components of the merger agreement.
Also, cash distributions of $2,346 were paid in 1994 by MTI to its shareholders
in the normal course of S-Corporation business prior to the date of acquisition.

</TABLE>


     The Company has established a valuation allowance for certain deferred tax
assets, including those for net operating loss and tax credit carryforwards.
Statement No. 109 requires that such a valuation allowance be recorded when it
is more likely than not that some portion of the deferred tax assets will not be
realized. The portion of the valuation allowance for deferred tax assets for
which subsequently recognized tax benefits will be applied directly to
contributed capital is $16,207 as of December 31, 1996. This amount is
attributable to differences between financial and tax reporting of employee
stock option transactions.

     As of December 31, 1996, the Company, for income tax purposes, has net
operating loss carryforwards of approximately $65,075, research and
experimentation credits carryforwards of $12,523 and a foreign tax credit
carryforward of 


                                                                              33
<PAGE>
$6,910. If not used by the Company to reduce income taxes payable in future
periods, net operating loss carryforwards will expire between 1999 through 2011,
research and experimentation credit carryforwards between 1998 through 2011 and
the foreign tax credit carryforward in the year 2001.

     The Company has not provided for Federal income taxes on approximately
$130,905 of undistributed earnings of foreign subsidiaries at December 31, 1996,
since these earnings have been invested indefinitely in subsidiary operations.
Upon repatriation, some of these earnings would generate foreign tax credits
which will reduce the Federal tax liability associated with any future foreign
dividend.

     The Company has settled its Federal income tax obligations through 1991.
The Company believes the provisions for income taxes for years since 1991 are
adequate.

     The Company capitalized software development costs amounting to $5,691 and
$8,129 in 1996 and 1995, respectively. Related amortization expense of $6,215,
$5,511, and $6,785 was recorded for the years ended December 31, 1996, 1995, and
1994, respectively.

     Acquisitions accounted for as purchases in 1996 and 1995, resulted in
goodwill capitalization of $5,517 and $528, and technology capitalization of
$8,957 and $892, respectively. Total purchased technology amortization expense
of $3,559, $2,418, and $760 was recorded for the years ended December 31, 1996,
1995, and 1994, respectively. Also, the Company recognized an impairment in
value of goodwill associated with its Meta subsidiary which resulted in a
write-down of $2,747. Goodwill costs are being amortized over a three year
period to R&D expense and technology costs are being amortized over a three year
period to system and software cost of revenues.

     During 1996, the Company sold common stock of two independent public
companies.


7.   Short-Term Borrowings

     Short-term borrowings represent drawings by subsidiaries under
multi-currency unsecured credit agreements and the current portion of long-term
debt. Interest rates are generally based on the applicable country's prime
lending rate depending on the currency borrowed. The weighted average interest
rate on short term borrowings during 1996 and 1995 was approximately 6%. The
Company has available lines of credit of approximately $30,506 as of December
31, 1996. Certain agreements require compensatory balances which the Company has
met.


8.   Long-Term Debt

Long-term debt is comprised of the following:

</TABLE>


     At December 31, 1996 and 1995, the Company had a committed credit facility
with a bank which remains in effect until July 2000. The commitment level at
December 31, 1996 was $52,480. The agreement requires commitment reductions of
$840 annually which began in July 1994, therefore the debt was reduced by $840
in 1996 and 1995. Also, $840 of the debt is classified as current in short-term
borrowings on the consolidated balance sheets as of December 31, 1996 and 1995.
Interest on borrowings under the credit facility is floating rate based.
Borrowings are collateralized by 


                                                                              34
<PAGE>
cash and investments of $30,000 and a trust deed on the Company's headquarters
site in Wilsonville, Oregon of $25,000.

     At December 31, 1996 and 1995, the Company had an interest rate swap
agreement with a bank, which effectively converts floating rates on $17,500 of
borrowings to a fixed rate of 9.55% until expiration of the agreement in January
2000. The average floating interest rate as of December 31, 1996 was
approximately 6%.

     Effective February 11, 1997, the Company terminated its $17.5 million
interest rate swap agreement at a cost of $1,650. In addition, in the first
quarter of 1997, the Company approved a plan to pay down the committed revolving
credit facility to zero by the end of the March 1997.


9.   Incentive Stock

     The Board of Directors has the authority to issue incentive stock in one or
more series and to determine the relative rights and preferences of the
incentive stock. The incentive stock is convertible into common stock upon
attainment of specified objectives or upon the occurrence of certain events to
be determined by the Board of Directors.


10.   Employee Stock and Savings Plans

     The Company has three common stock option plans which provide for the
granting of incentive and nonqualified stock options to key employees, officers,
and non-employee directors of the Company and its subsidiaries. The three stock
option plans are administered by the Compensation Committee of the Board of
Directors, and permit accelerated vesting of outstanding options upon the
occurrence of certain changes in control of the Company.

     The Company also has a stock plan which provides for the sale of common
stock to key employees of the Company and its subsidiaries. Shares can be
awarded under the plan at no purchase price as a stock bonus and the stock plan
also provides for the granting of nonqualified stock options.

     During 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123 "Accounting for Stock-Based
Compensation", which defines a fair value based method of accounting for an
employee stock option and similar equity instrument. As is permitted under
Statement No. 123, the Company has elected to continue to account for its
stock-based compensation plans under APB Opinion No. 25. The Company has
computed, for pro forma disclosure purposes, the value of all options granted
during 1996 and 1995 using the Black-Scholes option pricing model as prescribed
by Statement No. 123 using the following weighted average assumptions for
grants:

Year Ended December 31,               1996             1995
- ------------------------------------------------------------
Risk-free interest rate                 6%               6%
- ------------------------------------------------------------
Expected dividend yield                 0%               0%
- ------------------------------------------------------------
Expected lives                         5.5              5.5
- ------------------------------------------------------------
Expected volatility                    91%              94%
- ------------------------------------------------------------

     Using the Black-Scholes methodology, the total value of options granted
during 1996 and 1995 was $41,018 and $19,848, respectively, which would be
amortized on a pro forma basis over the vesting period of the options. The
weighted average fair value of options granted during 1996 and 1995 was $8.02
per share and $12.94 per share, respectively. If the Company had accounted for
its stock-based compensation plans in accordance with Statement No. 123, the
Company's net income (loss) and net income (loss) per share would approximate
the pro forma disclosures below:

     The effects of applying Statement No. 123 in this pro forma disclosure are
not indicative of future amounts. Statement No. 123 does not apply to awards
prior to January 1, 1995, and additional awards are anticipated in future years.

     Options under all four plans generally become exercisable over a four to
five-year period from the date of grant or from the commencement of employment
at prices generally not less than the fair market value at the date of grant.
The excess of the fair market value of the shares at the date of grant over the
option price, if any, is charged to operations ratably over the vesting period.
At December 31, 1996, options for 2,517 shares were exercisable, with a weighted
average exercise price of $7.87, 22,310 shares were reserved for issuance and
3,593 shares were available for future grant. Stock options outstanding, the
weighted average exercise price and transactions involving the stock option
plans are summarized as follows:

</TABLE>

     At December 31, 1996, the range of exercise prices and weighted average
remaining contractual life of outstanding options was $.07 - $19.76 and 8 years,
respectively.

     In November 1996, the Compensation Committee of the Board of Directors
adopted a resolution to offer employees holding nonqualified stock options for
2,595 shares the opportunity to exchange their existing stock options for new
nonqualified stock options. The exchange allowed employees to receive options
for the same number of shares at $7.75 per share, the then current market price,
instead of an average original exercise price of $14.17. The new options vest
over two to six years. The offer was made because the Board of Directors
believes lower-priced options provide a greater retention advantage and
incentive to key employees and officers. Option holders elected to exchange
options covering 1,791 shares.

     In May 1989, the shareholders adopted the 1989 Employee Stock Purchase Plan
and reserved 1,400 shares for issuance. The shareholders have subsequently
amended the plan to reserve an additional 4,000 shares for issuance. Under the
plan, each eligible employee may purchase up to six hundred shares of stock per
quarter at prices no less than 85% of its fair market value determined at
certain specified dates. Employees purchased 516 and 382 shares under the plan
in 1996 and 1995, respectively. At December 31, 1996, 1,899 shares remain
available for future purchase under the plan. The plan will expire upon either
issuance of all shares reserved for issuance or at the discretion of the Board
of Directors. There are no plans to terminate the plan at this time.

     The Company has an employee savings plan (the Savings Plan) that qualifies
as a deferred salary arrangement under Section 401(k) of the Internal Revenue
Code. Under the Savings Plan, participating U.S. employees may defer a portion
of their pretax earnings, up to the Internal Revenue Service annual contribution
limit. The Company currently matches 50% of eligible employee's contributions,
up to a maximum of 6% of the employee's earnings. Employer matching
contributions vest over 5 years, 20% for each year of service completed. The
Company's matching contributions to the Savings Plan were $2,299, $2,220, and
$1,997 in 1996, 1995, and 1994, respectively.


11.   Commitments

     The Company leases a majority of its field office facilities under
noncancellable operating leases. In addition, the Company leases certain
equipment used in its research and development activities. This equipment is
generally leased on a month-to-month basis after meeting a six-month lease
minimum.

     The Company rents its Japanese facilities under a two year cancelable lease
with a six month notice of cancellation. The total commitment under this
cancelable lease, which expires in December 1998, is $5,382, of which the first
six months payments of $1,345 are included in the schedule below. Future minimum
lease payments under all noncancellable operating leases are approximately as
follows:

REPORTS OF MANAGEMENT AND INDEPENDENT AUDITORS

Report of Management

     Management of Mentor Graphics Corporation is responsible for the
preparation of the accompanying consolidated financial statements. The
consolidated financial statements have been prepared in conformity with
generally accepted accounting principles appropriate in the circumstances and
necessarily include some amounts which represent the best estimates and
judgments of management. The consolidated financial statements have been audited
by KPMG Peat Marwick LLP, independent auditors, whose report is included on this
page.

     The Audit Committee of the Board of Directors is comprised of three
directors who are not officers or employees of Mentor Graphics Corporation or
its subsidiaries. These directors meet with management and the independent
auditors in connection with their review of matters relating to the Company's
annual financial statements, the Company's system of internal accounting
controls, and the services of the independent auditors. The Committee meets with
the independent auditors, without management present, to discuss appropriate
matters. The Committee reports its findings to the Board of Directors and also
recommends the selection and engagement of independent auditors.

Independent Auditors' Report

To the Stockholders and Board of Directors
Mentor Graphics Corporation:

     We have audited the accompanying consolidated balance sheets of Mentor
Graphics Corporation and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the years in the three-year period ended December 31, 1996.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

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

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Mentor
Graphics Corporation and subsidiaries as of December 31, 1996 and 1995, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1996 in conformity with generally accepted
accounting principles.

     As discussed in Note 1 to the consolidated financial statements, the
Company adopted the provisions of the Financial Accounting Standards Board's
Statement of Financial Accounting Standards (SFAS) No. 115, "Accounting for
Certain Investments in Debt and Equity Securities" in 1994.
