ITEM 1. BUSINESS.
 
    The MacNeal-Schwendler Corporation ("MSC" or the "Company") was incorporated
in Delaware in 1994. Since its inception in 1963, the Company has been engaged
in computer-aided engineering ("CAE"), including the development and marketing
of software for use principally by engineers and designers in industry, research
laboratories and universities. In the last two years, the Company has expanded
its scope to focus on providing engineering solutions through strategic
consulting, software integration, and customization services in addition to
engineering software sales. The Company's principal software products are
MSC/NASTRAN and MSC/PATRAN. Each product has been adapted over the years so that
it is compatible with most of the computer hardware platforms currently used by
engineers.
 
    In the current computer-aided manufacturing ("CAM") environment, designs are
subjected to engineering analysis before manufacturing has begun. MSC/NASTRAN is
a basic CAE analytical tool. MSC/PATRAN is an interactive CAE environment that
facilitates the use of geometric data from popular computer-aided design ("CAD")
systems such as CATIA, Pro/ENGINEER, and EDS/Unigraphics in a variety of
commercial analysis programs including MSC/NASTRAN. The use of CAE analysis
helps to get products to market faster, reduce product cost, and increase
reliability. CAE analysis can be used to simulate the performance of a design
prior to its physical manufacture, replacing time-consuming and costly manual
analyses and physical testing and permits a substantial increase in the number
of design trade-offs and design cycles. The Company's CAE tools are used by
engineers worldwide in several industries, including aerospace, automotive,
shipbuilding, consumer products and electronic packaging.
 
    MSC/NASTRAN, is a descendant of NASTRAN-Registered Trademark-, a computer
program owned by the United States Government and leased to others. Since
NASTRAN was first released in 1970, its contents and MSC/NASTRAN have rapidly
diverged, and the current capabilities and scope of MSC/NASTRAN are
substantially greater than those of NASTRAN. MSC commenced offering its
proprietary version as a commercial product in 1971. Pursuant to a 1982
agreement with the National Aeronautics and Space Administration, MSC acquired
the perpetual rights to commercially use those elements of NASTRAN which are
embodied in MSC/NASTRAN. See "Intellectual Property Rights" below.
 
    MSC offers the following CAE products in addition to MSC/NASTRAN and
MSC/PATRAN:
 
        MSC/DYTRAN--a tool used to solve highly nonlinear, transient dynamic
        problems, including those involving high speed impact, and
        fluid-structure interaction problems.
 
        MSC/SuperForge--a tool for the simulation of complex forging operations.
 
        MSC/SuperModel--provides automatic assembly of airframe and launch
        vehicle models.
 
        MSC/MVISION--a materials data management system for test, design and
        analysis engineers.
 
        MSC/NASTRAN for Windows--an integrated finite element modeling and
        analysis system for Windows NT, Windows 95, and Windows 3.1.
 
        MSC/InCheck--a series of software tools to be used in conjunction with
        "mid-range" CAD tools such as Autodesk Mechanical Desktop, Solidworks
        and Solid Edge. It is a Wizard-driven product.
 
    As an extension of its software business, the Company develops educational
tools designed to train users of MSC/NASTRAN, MSC/PATRAN and its other products.
Training seminars are conducted in local languages on a frequent basis at the
MSC Institute of Technology in Costa Mesa, California, at the Company's Los
Angeles headquarters, at MSC's offices worldwide, and at actual client sites. In
addition,
 
                                       2
<PAGE>
the Company now provides a broad range of engineering software consulting
services. A typical assignment might include all or some of the following
activities:
 
    - design/analysis process audits, wherein we will contract to examine the
      current practice in a customer's operation and, based on our worldwide
      experience in similar operations, benchmark that process against the
      industry
 
    - process reengineering planning, wherein we will contract to define an
      improved process state and provide a roadmap of changes to be made to
      achieve that improved state
 
    - reengineering implementation, wherein we will contract to make the
      recommended changes, often introducing new software tools and analysis
      techniques. The tools may be our own or those of other third parties.
      Often process change includes integration with the customer's Product Data
      Management (PDM) system and possibly the Enterprise Resource Management
      (ERM) system
 
    - software customization, wherein we will contract to modify our software
      products to capture particular features of the client's process or
      methodology
 
    - proprietary software commercialization, wherein we will contract to
      commercialize proprietary software programs to reduce the client's support
      costs, increase the sources of input for technological advance and/or
      increase access to the software for the client's supply chain
 
    The following is a detailed discussion of each of the Company's major CAE
products:
 
MSC/NASTRAN
 
    MSC/NASTRAN is based upon the "finite element method" (FEM) of analysis.
With FEM, complex structures are divided into small elements which form a finite
element model. The model is then subjected to computer analysis. MSC/NASTRAN is
used to analyze structures in order to determine, among other things, their
strength, safety and performance characteristics. For example, in the aerospace
industry, MSC/NASTRAN is employed to determine the stress distribution in the
major parts of an aircraft, such as engines, wings, fuselage and tail. The
computer analysis could be applied, for example, to improve the design of
aircraft by suggesting the removal of material where stresses are low and the
addition of material where stresses are high, while creating a reduced usage of
prototypes and other testing. With this knowledge, aircraft can be made both
stronger and lighter. The same principles have been applied to improve the
design of jets, rockets, engines, automobiles, trucks, tires, ships, farm
equipment, heavy industrial equipment, nuclear containment vessels, helicopters,
spacecraft and other products and structures.
 
    Additional types of structural analysis are also provided by MSC/NASTRAN,
including analyses of vibration characteristics, dynamic response, transient
heat transfer, elastic stability and aeroelastic response, including flutter.
The sequence of calculations required for each such analysis is prearranged. The
user need only provide a physical description of the problem and the desired
output.
 
    Because MSC/NASTRAN has been designed in a modular way, new features can be
added and obsolete features replaced without disrupting the other modules of the
system. As a result, major changes in computer hardware have been systematically
accommodated. For example, the program has been adapted to be used on
minicomputers and microcomputers, including Windows based personal computers.
The Company believes that the continued development and maintenance of
MSC/NASTRAN, together with the modular design features of the program, have
prevented, and will continue to prevent, its obsolescence, although no assurance
can be given that future changes in hardware or breakthroughs in software design
will not result in the obsolescence of the program.
 
    MSC/NASTRAN is currently operational on a wide variety of computer operating
system/hardware platform combinations, including those manufactured and
distributed by International Business Machines Corporation ("IBM"), Digital
Equipment Corporation ("DEC"), Hewlett-Packard Corporation ("HP"),
 
                                       3

Hitachi Data Systems, Nippon Electric Corporation ("NEC"), Silicon Graphics Inc.
("SGI"), Fujitsu Ltd., Siemens GmbH, and Sun Microsystems Inc. ("SUN").
 
MSC/PATRAN
 
    MSC/PATRAN provides finite element modeling, analysis data integration,
analysis simulation, and results evaluation capabilities required for analysts
to simulate product performance early in the design-for-manufacture process.
With MSC/PATRAN, an engineer is able to visualize the design, interface with
other CAD programs, perform pre-processing to prepare the computer model for
engineering analysis, and perform post processing of the results of the analysis
to assist in interpretation and visualization of the results, as well as
integration of analysis data with testing software packages. All of the
functions of the software can be integrated, automated and tailored to the
user's specific requirements using a powerful programming command language.
 
    The MSC/PATRAN system can be described as software that provides three
fundamental functions:
 
        MSC/PATRAN CORE SOFTWARE--The core of the MSC/PATRAN software enables
        the engineer to visualize the design, preprocess the design into a
        computer model for engineering analysis, and postprocess the results of
        the analysis into a graphical representation. The software interfaces
        with many popular CAD programs and many analysis packages such as
        MSC/NASTRAN.
 
        APPLICATION MODULES--Through a series of modules that can be added to
        the core software, engineers can perform analysis on stress, thermal
        mechanisms and dynamics, fluid flow, solid modeling, and fatigue.
        Certain of these application modules have been developed by third
        parties and are marketed under joint development or marketing
        agreements.
 
        INTERFACES--MSC/PATRAN uses a series of interfaces that allow it to
        interact with programs developed by other companies in the CAD/CAM/CAE
        industry. These interfaces either involve direct links into other
        software or translate data to and from other software so that it can be
        processed within MSC/PATRAN.
 
        Currently, the Company focuses its development activities with respect
        to MSC/PATRAN on hardware platforms from HP, SUN, SGI, IBM, DEC, and
        PC's based on Intel processors.
 
MSC/DYTRAN
 
    MSC/DYTRAN is designed to analyze transient, dynamic events characterized by
large structural distortions or the interaction of fluids with structures. Using
MSC/DYTRAN, engineers can solve many practical problems, including automotive
crash simulations, vehicle occupant safety studies, aircraft crash-worthiness
studies, forging studies and drop-test simulations.
 
    MSC/DYTRAN is also suitable for analyzing highly nonlinear and complex
processes such as the ingestion of objects into jet engines, hypervelocity
particle impacts upon spacecraft, the deployment of airbags in vehicle crashes,
accident containment during the transportation of hazardous cargo, and ballistic
armament penetration. With MSC/DYTRAN, engineers in a broad range of industries
can conduct "what if" studies involving the dynamic response and interaction of
fluids and structures subjected to high velocity impact. Events characterized by
rapid energy releases, such as explosions, can also be simulated. MSC/DYTRAN has
been used to successfully simulate phenomena as diverse as ship collisions, the
seismic response of structures to earthquakes, the performance of munitions and
armor, the safety tolerances of nuclear and chemical plant components, and
automobile crashes.
 
                                       4
<PAGE>
MSC/MVISION
 
    MSC/MVISION is a materials software system for visualization, selection and
data integration which helps companies take advantage of state-of-the-art
materials technology throughout the design-to-manufacture process. MSC/MVISION
electronically integrates data across engineering boundaries. It allows users to
build their own proprietary materials database and provides access to that data
across all engineering disciplines. It provides users with the ability to
search, query, compare and manipulate materials data as well as with direct
access to these databanks from within MSC/PATRAN. MSC/ MVISION is being adopted
to the client-server hardware environment and is the technical basis for the
Company's other engineering data management capabilities.
 
MSC/SUPERMODEL
 
    MSC/SuperModel is an analysis process management and advanced aerospace
modeling solution that dramatically reduces the time required for design
simulation. Aerospace structures are designed, analyzed, and manufactured by
multiple companies, with each being responsible for a given component, such as a
wing or fuselage. These companies are also responsible for their component's
finite element model, which predicts stress and deflection. MSC/SuperModel
assembles a number of component models (submodels) into a complete model
(supermodel.) MSC/SuperModel automates the task of managing the component and
assembly processes, tasks to which aerospace companies previously devoted
significant time and effort.
 
RESEARCH AND DEVELOPMENT
 
    The Company continually expends significant amounts on the development and
maintenance of its suite of CAE software products, as well as on new product
research and development. During the years ended January 31, 1998, 1997, and
1996, approximately $25,194,000, $30,425,000, and $30,752,000, respectively, was
expended for software research and development. Of the amounts expended,
$12,909,000 in 1998, $9,025,000 in 1997, and $10,447,000 in 1996 were included
in software costs capitalized.
 
    The Company's development activities have historically involved adding new
capabilities to its family of CAE programs or converting those programs for use
on new computer platforms. Such activities are intended to prevent technological
obsolescence and assure the Company's clients the maximum flexibility in
selecting computer hardware. A decision to undertake development activity to
adapt MSC's software program for a particular computer is based upon the
Company's estimates regarding feasibility, cost and the size of the market for
the program in connection with the particular computer.
 
    Maintenance of MSC software products includes system integration, quality
assurance testing, error correction, and modifications to accommodate changes to
computer system software. Given the maturity of the Company's software, most
maintenance efforts stem from continuing new developments. Maintenance costs are
expensed as incurred.
 
    The Company has recently increased the portion of research and development
expenditure which is used for new product development and expects to continue
this trend. The Company now provides industry specific modules such as an
Automotive Modeling System and a Noise, Vibration and Harshness Manager for the
automobile industry.
 
MARKETING
 
    The Company markets its products through advertising in trade publications,
participation in industry trade shows and exhibits, training seminars conducted
worldwide, its existing client base and through complementary marketing
agreements with computer hardware manufacturers.
 
                                       5
<PAGE>
    Foreign marketing is generally conducted in the same manner as U.S.
marketing. The basic licensing agreements are substantially the same. Prices for
agreements originating with MSC's German subsidiary are generally stated in
German Marks and agreements originating within Japan are generally stated in
Japanese Yen. Agreements with customers in Asia-Pacific outside of Japan are
denominated in US dollars. The agreements stated in foreign currencies are
subject to currency fluctuations.
 
    REVENUE POLICY.  The Company provides a variety of licensing alternatives
for the use of its software products. MSC's software products have been
primarily offered on an annual pre-paid license basis. An annual pre-paid
license is set at a fixed rate for the period and provides for payment in
advance of use. Under the pre-paid agreement, license revenue is recognized at
the time of sale, while maintenance revenue, representing approximately 15% of
the revenue from a pre-paid license, is recognized ratably over the term of the
maintenance period. In recent years, demand has also increased for paid up
licenses for engineering software products. A paid up license provides
significant revenue at the original time of sale of the product, with smaller
payments for maintenance following the time of sale. The growth of paid up
licenses creates higher earnings volatility since larger amounts of revenue are
recognized at one time instead of over a period of time. Service revenue was
less than 8% of revenue in fiscal 1998. See Note 1 of Notes to Consolidated
Financial Statements for additional information with respect to the Company's
revenue recognition policy.
 
    SALES/SUPPORT OFFICES.  The Company maintains U.S. sales and client support
offices in Los Angeles, CA; Costa Mesa, CA; Santa Clara, CA; Sacramento, CA;
Denver, CO; Dallas, TX; Atlanta, GA; Minneapolis, MN; Milwaukee, WI; Huntsville,
AL; Reston, VA; Dayton, OH; Sparta, NJ; Boca Raton, FL; Chicago, IL; Detroit,
MI; Philadelphia, PA; Boston, MA; New York, NY; Indianapolis, IN; Rochester, NY;
Phoenix, AZ; and Seattle, WA areas. The Los Angeles office also serves as the
Company's headquarters. The other offices are staffed by sales and/or technical
support representatives who have engineering backgrounds and experience using
MSC products. These representatives market the Company's products, provide
training in their use, respond to user support calls and provide solutions for
CAE analysis throughout North America.
 
    The Company's products are marketed, distributed and supported outside of
North America through a network of foreign subsidiary offices.
 
    The Company's wholly-owned European subsidiary headquartered in Munich,
Germany, manages its own network of wholly-owned subsidiaries in the United
Kingdom, Italy, Spain, France, Norway, and The Netherlands. Other sales offices
are located in Moscow, Russia, Fribourg, Switzerland and Brno, Czech Republic.
In Asia Pacific, sales and service are handled through the Company's
wholly-owned subsidiary in Tokyo, Japan, with a branch office in Osaka, Japan,
as well as other sales offices in Taipei, Taiwan and Beijing, People's Republic
of China.
 
    Representative arrangements are also utilized in several European and Asia
Pacific countries as well as in India, Australia, and parts of Latin America.
 
    POST CONTRACT SUPPORT.  Client service is an integral aspect of the
Company's marketing program. The Company maintains toll-free numbers and a "hot
line" service for its clients. The Company has invested in advanced "call
center" technology to improve its capabilities.
 
    User manuals, training and quality assurance are also essential to the
Company's marketing program. The Company's user manuals are comprehensive and
updated on a regular basis. A staff of writers and editors manage the design,
writing, editing and preparation of user manuals as well as of training
materials and promotional literature. A periodic newsletter provides clients
with new information on the Company's products and services.
 
                                       6
<PAGE>
    Formal training for clients is conducted by the Company, ranging from
three-day introductory courses to intensive courses on specialized subjects for
experienced users. On site courses for clients are provided for larger user
organizations.
 
    The Company also hosts annual users' conferences in the United States,
Europe, Asia Pacific, Australia, and Latin America to gather data on client
needs, new engineering applications, and new trends in computing technology.
 
CUSTOMERS
 
    The Company's products are marketed internationally to clients from
aerospace, automotive, industrial, computer and electronics manufacturers, and
universities. These categories of clients accounted for 39%, 26%, 28%, 4%, and
3%, respectively, of the Company's revenues for the fiscal year ended January
31, 1998.
 
    For the year ended January 31, 1998, foreign export sales accounted for
approximately 56% of gross revenues, most of which were attributable to Europe
(28%) and Asia-Pacific (26%). The balance was attributable to Canada and South
America. The operating margins derived from the Company's foreign export sales
do not materially differ from its domestic operations. See Notes 8 and 10 of
Notes to Consolidated Financial Statements for additional information with
respect to the Company's foreign operations.
 
    No customer of the Company accounts for more than 10% of the Company's
consolidated revenues.
 
BACKLOG
 
    The Company does not maintain backlog statistics for its products because
software is generally available for delivery upon execution of a licensing
agreement or contract. Backlog for consulting services work is currently not
material.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.
 
1998 VS. 1997
 
    The Company reported revenue of $134,850,000 for the year ended January 31,
1998 compared to revenue of $133,321,000 for the year ended January 31, 1997, a
1% increase. Revenue growth in the current year would have been approximately
$8,000,000, or 7% if valued using prior year foreign currency translation rates.
Software license revenue and maintenance fees account for 93% of total reported
revenue in fiscal 1998 and 94% in fiscal 1997, with service revenue making up
the difference.
 
    Software revenue consists of licensing fees, which are fees charged for the
right to use the software, and maintenance fees, which provide for support and
upgrade privileges. In accordance with The American Institute of Certified
Public Accountant's ("AICPA") Statement of Position ("SOP") 91-1, "Software
Revenue Recognition" issued in 1991, revenue associated with support and upgrade
privileges has been consistently deferred and recognized over the term of the
license agreement.
 
    Fiscal 1998 revenue growth was adversely affected by the strength of the
U.S. Dollar compared to foreign currencies in which the Company operates. The
Company's revenue growth in fiscal 1998, measured in local currencies, was
approximately 8% compared to the 1% reported in U.S. Dollars. The Asia Pacific
region, which accounts for 26% of the Company's total revenue, grew by 10% in
local currency compared to fiscal 1997. Europe, which accounts for 28% of the
Company's total revenue, grew by 7% in local currency compared to fiscal 1997,
and the Americas, which accounts for 46% of the Company's total revenue reported
a 8% growth rate in fiscal 1998. In light of the economic turmoil in the
Asia-Pacific region, the Company remains cautious about its Asia-Pacific
prospects. Approximately 16% of the Company's total revenue comes from Japan as
part of the Asia-Pacific region.
 
    In addition to the currency impact, fiscal 1998 revenue growth was also
adversely affected by the sale of the electromagnetic product line in July 1996,
which contributed revenues of $2,459,000 in fiscal 1997.
 
    Operating expense of $113,603,000 in fiscal 1998 decreased by approximately
1% from the $114,278,000 reported in fiscal 1997.
 
    In accordance with the AICPA Statement of Financial Accounting Standards No.
86, "Accounting for the Costs of Computer Software to be Sold, Leased, or
Otherwise Marketed," cost of revenue expense includes period expenses directly
related to revenue as well as the amortization of capitalized software costs.
Research and development expense is reported net of the amount capitalized.
 
    In fiscal 1998, total reported cost of revenue was $25,655,000 compared to
$20,686,000 in fiscal 1997, an increase of $4,969,000 or 24%. Ninety percent or
$4,484,000 of the fiscal 1998 increase is due to the amortization of capitalized
software, which is a significant component of cost of revenue. Capitalized
software amortization increased to $12,358,000 in fiscal 1998 from $7,874,000 in
fiscal 1997. Royalty expense is also included in cost of revenue and paid to
third parties under various agreements. The Company does not consider any
royalty expense related to individual agreements to be material. The incremental
expense of providing maintenance services, and expenses associated with other
services were not deemed to be material in fiscal 1998 or 1997.
 
    Net research and development expense in fiscal 1998 of $12,285,000 was
$9,115,000 less than that reported in fiscal 1997. The decrease is the result of
a decrease of $5,231,000 in the total gross research and development investment
and an increase of $3,884,000 in the amount of research and development
investment required to be capitalized in fiscal 1998 compared to fiscal 1997,
which reduces the amount reported as expense.
 
    As noted above, research and development expense is reported net of
capitalized software costs. The total gross investment in research and
development activities in fiscal 1998 amounted to $25,194,000, or 19% of current
year revenue, compared to $30,425,000, or 23% of revenue in fiscal 1997. The
total decrease in research and development investment in fiscal 1998 of
$5,231,000 resulted primarily from
 
                                       12
<PAGE>
changes in staffing mix and staff makeup related to strategic revisions in
product development emphasis. The changes are in line with the Company's revised
goals and objectives for research and development.
 
    Capitalized software, which is a significant component of reported research
and development expense, was $12,909,000 in fiscal 1998 compared to $9,025,000
in fiscal 1997, an increase of $3,884,000. The amount of product development
capitalized in any given period is a function of many factors including the
number of products under development at any point in time as well as their stage
of development. The Company's product development process is continually under
review to improve efficiency, product quality, and reduce time to market. Due to
the continual change in the product development process there can be no
assurance that the level of development capitalized in future periods will be
comparable to current capitalized levels.
 
    Selling, general, and administrative expense in fiscal 1998 was $73,395,000
compared to $69,923,000 in fiscal 1997, an increase of $3,472,000, or 5%. The
increase relates primarily to expanded worldwide staffing requirements in the
sales and distribution area and was part of the change in customer focus
implemented during fiscal 1997.
 
    Operating income is affected by the amount of software capitalized and the
amortization thereof. Operating income, including software capitalization and
amortization, was $21,247,000 in fiscal 1998 compared to $19,043,000 in fiscal
1997, an increase of 12%. The net effect of the amortization and capitalization
of software costs was a $551,000 reduction of operating expenses in fiscal 1998
compared to a $1,151,000 reduction of operating expenses in fiscal 1997. Thus,
the operating income benefit from the amortization and capitalization of
software costs was $600,000 less in fiscal 1998 than fiscal 1997.
 
    Debenture interest reflects the interest on the convertible subordinated
debentures issued as part of the acquisition of PDA Engineering in 1994.
Interest payments are due on March 15 and September 15 of each year until the
debentures are converted or redeemed.
 
    Other income (expense) was income of $620,000 in fiscal 1998 compared to an
expense of $333,000 in fiscal 1997. The fluctuation is primarily attributable to
increased interest and investment income from $642,000 in fiscal 1997 to
$852,000 in fiscal 1998 and a reduction of foreign exchange losses from a loss
of $562,000 in fiscal 1997 to a loss of $25,000 in fiscal 1998. Other income
(expense) also includes gains and losses on sales of assets and other
non-operating income.
 
    The effective tax rate for the year was 34% compared to 32.5% in fiscal
1997. This change reflects an increase of $261,000 in income tax expense on a
year to year basis.
 
    Net income was $11,492,000 in fiscal 1998 compared to $9,621,000 in fiscal
1997, an increase of 20%. Net income in fiscal 1998 was unfavorably affected by
fluctuations in functional currencies used in the Company's international
operations. The fluctuation of the U.S. dollar versus these currencies could
continue to have an unfavorable effect in fiscal 1999 and future years. The
effect of foreign currency translation on net income was an unfavorable variance
of approximately $2,000,000 if valued using prior year foreign currency
translation rates.
 
1997 VS. 1996
 
    The Company reported revenue of $133,321,000 for the year ended January 31,
1997, an increase of 2% from $130,483,000 for the year ended January 31, 1996.
Revenue growth in fiscal 1997 would have been approximately $5,600,000, or 4%
greater, if valued using prior year foreign currency translation rates. A total
of 94% of total revenue in fiscal 1997 and 93% of revenue in 1996 was derived
from the licensing of the Company's software products and from software
maintenance fees with service revenue making up the difference.
 
    Software revenue consists of licensing fees, which are fees charged for the
right to use the software, and maintenance fees, which provide for support and
upgrade privileges. In accordance with the AICPA
 
                                       13
<PAGE>
SOP 91-1, "Software Revenue Recognition" issued in 1991, revenue associated with
support and upgrade privileges has been consistently deferred and recognized
over the term of the license agreement.
 
    Fiscal 1997 revenue growth was adversely affected by the strength of the
U.S. Dollar compared to foreign currencies in which the Company operates. The
Company's revenue growth in fiscal 1997, measured in local currencies, was
approximately 8% compared to the 2% reported in U.S. Dollars. The Asia-Pacific
region, which accounts for 26% of the Company's total revenue, grew by 18% in
local currency compared to the prior year. In U.S. dollar terms, the growth in
the Asia-Pacific region was 7%. Europe, which accounts for 30% of the Company's
total revenue, grew by 9% in local currency compared to the prior year and 3% in
U.S. dollar terms. The Americas, which accounts for 44% of the Company's total
revenue, reported a 2% decline in fiscal 1997.
 
    In addition to the currency impact, fiscal 1997 real growth was also
affected by the sale of the Electromagnetic Analysis product line (MSC/EMAS) in
July of 1996, which contributed revenue of $2,459,000 in fiscal 1997 and
$3,780,000 in fiscal 1996.
 
    Operating expenses of $114,278,000 in fiscal 1997 increased by approximately
8% from the $105,744,000 reported in fiscal 1996, an increase of $8,534,000.
This increase is attributable to many factors.
 
    In accordance with the AICPA Statement of Financial Accounting Standards No.
86, "Accounting for the Costs of Computer Software to be Sold, Leased, or
Otherwise Marketed," cost of revenue expense includes period expenses directly
related to revenue as well as the amortization of capitalized software costs.
Research and development expense is reported net of the amount capitalized.
 
    In fiscal 1997 total reported cost of revenue was $20,686,000 compared to
$19,856,000 in fiscal 1996, an increase of $830,000, or 4%. Amortization of
capitalized software cost, which is a significant component of cost of revenue,
was $7,874,000 in fiscal 1997 compared to $8,739,000 in fiscal 1996, a decrease
of $865,000. The increase in the cost of revenue expense is primarily due to
higher third-party royalty expenses brought about by increased revenues from
software products that carry a royalty obligation. Royalty expense is included
in cost of revenue and paid to third parties under various agreements. The
Company does not consider any royalty expense related to individual agreements
to be material. The incremental expense of providing maintenance services and
expenses associated with other services were not deemed to be material in fiscal
1997 or fiscal 1996.
 
    Net research and development expense in fiscal 1997 was $21,400,000 compared
to $20,305,000 in fiscal 1996, a $1,095,000 increase. The increase is the result
of a decrease of $1,422,000 in the amount of research and development investment
required to be capitalized in fiscal 1997 compared to fiscal 1996 and a decrease
of $327,000 in gross research and development expense.
 
    As noted above, research and development expense is reported net of
capitalized software costs. The total gross investment in research and
development activities in fiscal 1997 amounted to $30,425,000, or 23% of fiscal
1997 revenue, compared to $30,752,000, or 24% of revenue in fiscal 1996.
 
    Capitalized software, which is a significant component of research and
development expense, was $9,025,000 in fiscal 1997 compared to $10,447,000 in
fiscal 1996, a decrease of $1,422,000. The amount of product development
capitalized in any given period is a function of many factors, including the
number of products under development at any point in time, as well as their
stage of development. The Company's product development process is continually
under review to improve efficiency, product quality, and reduce time to market.
Due to the continual improvements in the product development process there can
be no assurance that the level of development capitalized in future periods will
be comparable to current capitalized levels.

    Selling, general, and administrative expenses in fiscal 1997 were
$69,923,000 compared to $63,163,000 in fiscal 1996, an increase of $6,760,000,
or 11%. The increase in sales and marketing expense is primarily related to the
expansion of the infrastructure in our international operations. The increases
in general and administrative expenses relate to the expansion of the Company's
worldwide information systems network, and, to a lesser extent, to an increase
in the Company's bad debt expense.
 
    Operating income is affected by the amount of software capitalized and the
amortization thereof. Operating income, including software capitalization and
amortization, was $19,043,000 in fiscal 1997 compared to $24,739,000 in fiscal
1996, a decrease of 23%. The net effect of the amortization and capitalization
of software costs was a $1,151,000 reduction of operating expenses in fiscal
1997 compared to a $1,708,000 reduction of operating expenses in fiscal 1996.
Thus, the operating income benefit from the amortization and capitalization of
software costs was $557,000 less in fiscal 1997 than fiscal 1996.
 
    Debenture interest reflects the interest on the Convertible Subordinated
Debentures issued as part of the acquisition of PDA Engineering in 1994.
Interest payments are due on March 15 and September 15 of each year until the
debentures are converted or redeemed.
 
    Other income (expense) was an expense of $333,000 in fiscal 1997 compared to
income of $823,000 in fiscal 1996. The fluctuation is primarily attributable to
the increased loss on exchange rates due to the significant strengthening of the
U.S. dollar versus the German mark and Japanese yen during fiscal 1997. The
exchange rate losses were partially offset by investment income, and gains and
losses on sales of assets.
 
    The effective tax rate for the year was 32.5% compared to 31.7% in fiscal
1996. This change reflects an increase of $114,000 in income tax expense on a
year to year basis.
 
    Net income was $9,621,000 in fiscal 1997 compared to $14,407,000 in fiscal
1996, a decrease of 33%. Net income in fiscal 1997 was unfavorably affected by
fluctuations in functional currencies used in the Company's international
operations. The effect of foreign currency translation on net income was an
unfavorable variance of approximately $1,800,000 if valued using prior year
foreign currency translation rates.
 
COMPANY TRENDS
 
    During fiscal 1998, the Company released the following products: MSC/AMS,
MSC/DropTest, MSC/ SuperForge, MSC/InCheck (for Mechanical Desktop, Solid Work,
and Solid Edge software), MSC/ CONSTRUCT, MSC/SuperModel, and MSC/NVH Manager.
 
    During fiscal 1997, the Company created market-oriented units to increase
focus on its customers. The Company believes that by organizing itself around
three core customer groups--Aerospace, Automotive, and Growth Industries--it can
provide customers with complete mechanical computer-aided engineering solutions
instead of simply selling software.
 
    Also during fiscal 1997, the Company acquired Automotive Analytics, Inc.,
which included an analysis tool specifically for automotive engineers, as well
as a group of consultants experienced at applying CAE techniques to support the
automotive engineering design process.
 
OPERATING PATTERN
 
    Of the 93%, 94% and 93% of the Company's revenues in fiscal 1998, 1997 and
1996, respectively, that consisted of software license and maintenance revenue,
approximately 71% in fiscal 1998, 73% in fiscal 1997, and 70% in fiscal 1996 of
the software license and maintenance revenue is derived from annual renewable
leases and recurring maintenance fees with the remaining 22% in fiscal 1998, 21%
in fiscal 1997, and 23% in fiscal 1996 related to paid-up licenses.

LIQUIDITY AND CAPITAL RESOURCES
 
    Working capital needed to finance the Company's growth in the past has been
provided by cash on hand and cash flow from operations. Management believes that
cash generated from operations will continue to provide sufficient capital for
working capital needs in the foreseeable future. Net cash from operating
activities was $18,756,000, $28,439,000, and $25,977,000 in fiscal 1998, 1997,
and 1996, respectively. Fiscal 1998 net cash from operating activities was
affected by the increase in accounts receivable at year end. The Company's
working capital at January 31, 1998 was $47,753,000, compared to $33,029,000 at
January 31, 1997. The Company has an agreement with its principal bank for a
$15,000,000 unsecured line of credit at the prevailing prime rate. No amounts
were outstanding under this line of credit as of January 31, 1998 or January 31,
1997.
 
    The Company issued convertible subordinated debentures in August 1994, in
connection with the PDA acquisition, in the aggregate amount of approximately
$56,608,000. The debentures bear interest at 7 7/8% with interest payments due
semi-annually in March and September. Each semi-annual interest payment was
approximately $2,200,000 in fiscal 1998. The amount of interest will decrease if
the debentures are converted into common stock. The debentures mature in August
2004.
 
    Management expects to continue to invest a substantial portion of the
Company's revenues in the research and development of new computer software
products and the enhancement of existing products. The Company expended a total
of $25,194,000, $30,425,000, and $30,752,000 in fiscal 1998, 1997, and 1996,
respectively, on research and development efforts of which $12,909,000,
$9,025,000, and $10,447,000 were capitalized in fiscal 1998, 1997, and 1996,
respectively. Product development costs and the capitalization rate may vary
depending, in part, on the number of products and the stage of development of
the products in process.
 
    During the years ended January 31, 1998, 1997 and 1996, the Company acquired
$4,436,000, $4,591,000, and $7,885,000, respectively, of new property and
equipment. Capital expenditures during fiscal 1998 included significant upgrades
in computer equipment in order to keep current with technological advances and
expansion of facilities worldwide. The Company's capital expenditures vary from
year to year, as required by business needs. The Company intends to continue to
expand the capabilities of its computer equipment used in the development and
support of its proprietary software products. Management expects expenditures
for property and equipment in fiscal years 1999 and 2000 to be consistent with
those for the fiscal year ended January 31, 1998.
 
    The Company sold its Electromagnetics Business Unit ("EBU") to Ansoft
Corporation for $5,600,000 in July 1996, which did not result in a material
effect on earnings. The sale of the unit did not materially affect fiscal 1997
net income compared to prior years because of the relatively small size compared
to the Company's overall operations. However, the sale did significantly improve
both the Company's cash position and its cash used in investing activities,
compared to prior years. The Company is not contemplating other similar sales in
the foreseeable future.
 
    During the middle of fiscal 1997, the Company eliminated its quarterly
dividend in order to reinvest more of its earnings into its operations. Dividend
payments were made on the Company's common stock in the aggregate amounts of
$5,111,000 and $8,571,000 in the years ended January 31, 1997 and 1996,
respectively. The Company does not plan to reinstate the payment of dividends in
the foreseeable future.
 
IMPACT OF YEAR 2000
 
    The Company has initiated formal communications with all of its significant
suppliers and large customers to determine the extent to which the Company's
internal applications and other interface systems are vulnerable to those third
parties' failure to remediate their own Year 2000 issues. The Company has
determined that the purchased software applications it uses and software
applications developed internally are Year 2000 compliant. However, there is no
guarantee that other systems of other
 
                                       16
<PAGE>
companies on which the Company's systems rely will be timely converted and would
not have an adverse effect on the Company's systems.
 
    The Company has completed a study on the software that is sold to customers.
The study determined that all software sold by the Company was Year 2000
compliant. The cost of this study was immaterial.
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In December 1997, the Financial Accounting Standards Board ("FASB") issued
Statement No. 128, "Earnings per Share." SFAS No. 128 replaced the calculation
of primary and fully diluted earnings per share with basic and diluted earnings
per share. Unlike primary earnings per share, basic earnings excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All earnings per share amounts for all periods have been
presented, and where appropriate, restated to conform to the FASB No. 128
requirements.
 
    In June 1997, the FASB issued Statement 130, "Reporting Comprehensive
Income". SFAS No. 130 establishes new rules for the reporting and display of
comprehensive income and its components; however, adoption in fiscal 1999 will
have no impact on the Company's net income or shareholders' equity. SFAS No. 130
requires unrealized gains or losses on the Company's available-for-sale
securities and the foreign currency translation adjustments, which currently are
reported in shareholders' equity, to be included in other comprehensive income
and the disclosure of total comprehensive income. The Company will adopt SFAS
No. 130 in the first quarter of fiscal 1999.
 
    In December 1997, the FASB issued Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information," which requires the Company
to disclose certain information about reportable operating segments in complete
sets of financial statements of the enterprise and in condensed financial
statements of interim periods. The Company will adopt SFAS No. 131 in fiscal
1999.
 
    In October 1997, the Accounting Standards Executive Committee ("AcSEC") of
the AICPA issued SOP 97-2, "Software Revenue Recognition," which supercedes
Statement of Position 91-1. This method distinguishes between significant and
insignificant vendor obligations as a basis for recording revenue with a
requirement that each element of a software licensing arrangement be separately
identified and accounted for based on relative fair values of each element. The
Company will adopt SOP 97-2 in the first quarter of fiscal 1999. The Company is
currently analyzing the requirements of SOP 97-2. The ultimate impact on the
Company's fiscal 1999 financial statements is uncertain until this analysis is
complete.
 
INFLATION
 
    Inflation in recent years has not had a significant effect on the Company's
business.

                       THE MACNEAL-SCHWENDLER CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BUSINESS INFORMATION
 
    BUSINESS  The Company designs, produces, and markets proprietary computer
software products and provides related services for use in computer-aided
engineering. The Company's products are marketed internationally to aerospace,
automotive, and other industrial concerns, computer and electronics
manufacturers, and universities.
 
    PRINCIPLES OF CONSOLIDATION  The consolidated financial statements include
the accounts of the Company and its subsidiaries. All significant intercompany
accounts and transactions have been eliminated.
 
    USE OF ESTIMATES  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
    REVENUE RECOGNITION  Revenue is recognized in accordance with AICPA's issued
Statement of Position 91-1 "Software Revenue Recognition". Software revenue
consists of licensing fees, which are fees charged for the right to use the
software, and maintenance fees, which consist of support and upgrade privileges.
Revenue from monthly leases of the Company's computer software products is
recognized monthly as earned. Revenue from prepaid and paid-up licenses is
recognized in full upon the delivery of the software, with postcontract customer
support ("PCS") on such licenses deferred and recognized over the term of the
PCS agreement, generally one year. There are no material incremental costs
associated with PCS or upgrade privileges. Revenue from the sale of products
provided by other suppliers and for which a royalty is due the suppliers is
reported as gross revenues earned from the product sale. Royalty due to the
supplier represents an operating expense and is recorded as royalty expense in
cost of revenue. Service and other revenues are recognized when the service is
provided and the revenue has been earned. Long term contracts are recognized
using the percentage of completion method. Services revenue and costs associated
with services revenue are not material. Discounts on the sale of computer
software products and PCS are proportionately allocated to each element of a
sale based on the list price of each element.
 
    STOCK-BASED COMPENSATION  The Company grants stock options for a fixed
number of shares to employees with an exercise price equal to the fair value of
the shares at the date of grant. The Company accounts for stock option grants in
accordance with APB Opinion No. 25, Accounting for Stock Issued to Employees,
and, accordingly, recognizes no compensation expense for the stock option
grants. The Company has also made available an Employee Stock Purchase Plan for
eligible employees. Such eligible employees are entitled semi-annually to
purchase common stock, by means of limited payroll deductions at a 10% discount
from the fair market value of the common stock as of specific dates. In 1997,
the Company adopted the disclosure only provisions of SFAS No. 123, "Accounting
For Stock-Based Compensation". Refer to Note 12: Stock Option Plans.
 
    RECLASSIFICATIONS  The consolidated financial statements for 1997 and 1996
contain certain reclassifications to conform to the 1998 presentation.
 
    CASH, CASH EQUIVALENTS AND AVAILABLE FOR SALE SECURITIES  For purposes of
the consolidated statements of cash flows, the Company considers investments in
money market instruments to be cash equivalents. Marketable equity securities
and debt securities are classified as held-to-maturity or as available-for-sale.
Management determines the appropriate classification of debt securities at the
time of purchase and reevaluates such designation as of each balance sheet date.
At January 31, 1998 and 1997, all securities
 
                                       22

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BUSINESS INFORMATION
(CONTINUED)
were designated as available-for-sale. Available-for-sale securities are carried
at fair value, with the unrealized gains and losses, net of tax, reported in a
separate component of shareholders' equity. Available-for-sale securities held
by the Company are principally municipal debt securities. Unrealized gains and
losses did not have a material effect on equity at January 31, 1998 or January
31, 1997. Refer to Note 3: Available for Sale Securities.
 
    ACCOUNTS RECEIVABLE  Accounts receivable are reported net of allowances for
doubtful accounts. The Company's revenue is generated from customers in
diversified industries, primarily in North America, Europe and Asia-Pacific. The
Company performs ongoing credit evaluations of its customers and generally does
not require collateral. The Company maintains reserves for potential credit
losses and such losses have been within management's expectations.
 
    PROPERTY AND EQUIPMENT  Depreciation and amortization are computed on the
straight-line method over the estimated useful lives of assets, ranging from two
to five years.
 
    CAPITALIZED SOFTWARE COSTS  Capitalized software costs are comprised of
purchased software and internal software development costs. Software costs
incurred subsequent to the determination of the software product's technological
feasibility are capitalized. Capitalization ceases and amortization of
capitalized costs begins when the software product is available for general
release to clients. Capitalized software amortization expense is included in
cost of revenue. The amortization period for the software costs capitalized is
the economic life of the related products, typically three to four years.
 
    GOODWILL AND OTHER INTANGIBLE ASSETS  Goodwill amounting to approximately
$9,950,000 and $11,456,000 net of accumulated amortization of $5,238,000 and
$3,732,000 as of January 31, 1998 and 1997, respectively, arising from
acquisitions is amortized on the straight-line basis over a period of 10 years.
Other intangibles amounted to approximately $4,008,000 and $4,809,000, net of
accumulated amortization as of January 31, 1998 and 1997, respectively, and are
amortized on a straight-line basis over five to 10 years. Accumulated
amortization of other intangibles as of January 31, 1998 and 1997, amounted to
$2,731,000 and $1,968,000, respectively. The carrying value of intangibles is
evaluated periodically in relation to the operating performance and future
undiscounted cash flows of the underlying business. Adjustments are made if the
sum of expected future net cash flows is less than book value. No adjustments
have been made in the periods presented.
 
    ADVERTISING EXPENSE  The cost of advertising is expensed as incurred. The
Company incurred $1,282,000, $1,431,000, and $1,229,000 in advertising costs
during fiscal 1998, 1997, and 1996, respectively.
 
    ROYALTIES TO THIRD PARTIES  The Company has several agreements with third
parties requiring the payment of royalties for sales of third party products, or
inclusion of such products as a component of the Company's products. The Company
does not consider any royalty expense related to individual agreements to be
material.
 
    INCOME TAXES  The Company utilizes the asset and liability method of
accounting for income taxes. Provision is made in the Company's financial
statements for current income taxes payable and deferred income taxes arising
primarily from temporary differences in accounting for capitalized software
costs, undistributed earnings of international subsidiaries, depreciation
expense, deferred income and state income taxes.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BUSINESS INFORMATION
(CONTINUED)
    EFFECT OF FOREIGN CURRENCY  The Company translates the assets and
liabilities of its foreign subsidiaries at the rate of exchange in effect at the
period end. Revenues and expenses are translated using an average of exchange
rates in effect during the period. Translation adjustments are recorded as a
separate component of shareholders' equity in the consolidated balance sheet.
 
    DERIVATIVE INSTRUMENT  The Company enters into forward exchange contracts to
hedge certain anticipated repayments of its intercompany debt with its foreign
subsidiaries. The forward exchange contracts do not qualify as a hedge for
financial reporting purposes and, accordingly, unrealized gains or losses based
on the current forward foreign exchange rates are reflected directly in income.
Refer to Note 13: Commitments.
 
    EARNINGS PER SHARE  In December 1997, the FASB issued Statement No. 128,
"Earnings per Share." SFAS No. 128 replaced the calculation of primary and fully
diluted earnings per share with basic and diluted earnings per share. Unlike
primary earnings per share, basic earnings excludes any dilutive effects of
options, warrants and convertible securities. Diluted earnings per share is very
similar to the previously reported fully diluted earnings per share. Diluted
earnings per share for 1998 and 1997 assumes the convertible subordinated
debentures were converted into common stock at the beginning of the period and
the related interest requirements, net of tax, is added to net income in the
calculation. All earnings per share amounts for all periods have been restated
to conform to the FASB No. 128 requirements.
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In June 1997, the Financial Accounting Standards Board issued Statement 130,
"Reporting Comprehensive Income". SFAS No. 130 establishes new rules for the
reporting and display of comprehensive income and its components; however,
adoption in fiscal 1999 will have no impact on the Company's net income or
shareholders' equity. SFAS No. 130 requires unrealized gains or losses on the
Company's available-for-sale securities and the foreign currency translation
adjustments, which currently are reported in shareholders' equity, to be
included in other comprehensive income and the disclosure of total comprehensive
income. The Company will adopt SFAS No. 130 in the first quarter of fiscal 1999.
 
    In December 1997, the FASB issued Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information," which requires the Company
to disclose certain information about reportable operating segments in complete
sets of financial statements of the enterprise and in condensed financial
statements of interim periods. The Company will adopt SFAS No. 131 in the first
quarter of fiscal 1999.
 
    In October 1997, the AcSEC of the AICPA issued Statement of Position ("SOP")
97-2, "Software Revenue Recognition," which supercedes Statement of Position
91-1. This method distinguishes between significant and insignificant vendor
obligations as a basis for recording revenue with a requirement that each
element of a software licensing arrangement be separately identified and
accounted for based on relative fair values of each element. The Company will
adopt SOP 97-2 in the first quarter of fiscal 1999. The Company is currently
analyzing the requirements of SOP 97-2. The ultimate impact on the Company's
fiscal 1999 financial statements is uncertain until this analysis is complete.
 
NOTE 2: DIVESTITURES
 
    In July 1996, the Company sold its Electromagnetics Business Unit to Ansoft
Corporation for $5,600,000, which did not result in a material effect on
earnings. The sale of the unit did not materially

dates through the year 2010. An acquisition by the Company in 1993 constituted
an ownership change for federal income tax purposes and as a result, the amount
of net operating loss carryforward that may be utilized in any given year may be
limited. For financial reporting purposes, a valuation allowance of $5,442,000
at January 31, 1998, $5,800,000 at January 31, 1997, and $5,904,000 at January
31, 1996 has been recognized to offset the deferred tax assets relating to
recent acquisitions. The decrease in the valuation allowance was $358,000 in
1998 and $104,000 in 1997.

NOTE 11: EMPLOYEE BENEFITS
 
    The Company contributes an amount, integrated with Social Security, to a
defined contribution plan, covering substantially all North American full-time
employees who have completed a specified term of service with the Company.
Contributions charged to expense in connection with this plan were approximately
$2,694,000 in 1998, $2,960,000 in 1997, and $3,019,000 in 1996. The plan has a
401(k) feature to permit voluntary employee contributions, which does not affect
the Company's expenses.
 
    The Company adopted a non-qualified supplemental retirement plan during the
year ended January 31, 1995. The Company contributes an amount, integrated with
Social Security and the Company's defined contribution plan, covering certain
key employees who have completed a specified term of service with the Company.
Contributions charged to expense in connection with this plan were approximately
$134,000 in 1998, $148,000 in 1997, and $135,000 in 1996.
 
    The Company also has a post retirement health care plan for employees
completing minimum age and years of service requirements. The plan provides for
a benefit offsetting premiums for health care coverage. The amount of the
benefit is based on a combination of the age of the participant and the number
of years of service at retirement. The gross accumulated post-retirement
obligation was approximately $1,271,000 and $1,551,000 at January 31, 1998 and
1997, respectively. The Company is recognizing past service cost over 20 years.
Total expense for the years ended January 31, 1998, 1997 and 1996 was $347,000,

provided for the granting of options for the purchase of up to 900,000
authorized but unissued shares of the Company's Common Stock, at option prices
of not less than the fair market value of the common shares at the date of
grant. The options become fully exercisable one year from the date of grant and
expire five years after the date of grant. The 1983 Plan expired during fiscal

1991 PLAN
 
    The MacNeal-Schwendler 1991 Stock Option Plan, as amended, consists of two
parts--a "Key Employee Program" that allows discretionary awards of
nontransferable incentive stock options and nonqualified stock options to
officers and other key employees, and a "Non-Employee Director Program" that
provides for automatic annual grants of nontransferable, nonqualified stock
options to non-employee directors.
 
    The "Key Employee Program" section of the 1991 Plan provides for the
granting of both incentive stock options and nonqualified options for the
purchase of up to 2,500,000 authorized but unissued shares of the Company's
common stock at the fair market value of such shares on the date the option is
granted, or for non-qualified options at such price as the Compensation
Committee may determine.
 
    The "Non-Employee Director Program" section of the 1991 Plan provides for
automatic grants to members of the Board of Directors who are not officers or
employees of the Company or its subsidiaries. A maximum of 500,000 shares of
Company authorized but unissued common stock may be issued upon the exercise of
options under the "Non-Employee Director Program." All eligible directors will
receive annual non-discretionary grants of non-qualified stock options for the
purchase of 3,000 shares of the Company's common stock.
 
    Options under the 1991 Plan are exercisable up to ten years from the date of
grant, subject to vesting provisions outlined at the grant date.

    At January 31, 1998 and 1997, the per share weighted-average exercise prices
of the stock options exercisable under the 1991 Plan were $11.73 and $13.40, and
under the 1983 Plan were $14.25 and $14.00, respectively. Options for the
purchase of 588,250 and 699,500 shares were available for future grant as of
January 31, 1998 and 1997, respectively. At January 31, 1998 the
weighted-average remaining contractual life for stock options granted under the
1991 Plan and 1983 Plan was 6 years and 1 year, respectively.
 
EMPLOYEE STOCK PURCHASE PLAN
 
    In September 1996, the Company's Board of Directors adopted The
MacNeal-Schwendler Corporation 1996 Employee Stock Purchase Plan. This Plan was
approved by the shareholders at the 1997 annual meeting of shareholders. Under
the Plan, a maximum of 750,000 shares of the Company's common stock have been
made available for purchase by eligible employees electing to participate in the
Plan. The Plan is intended to provide an additional incentive to participating
eligible employees, through ownership of common stock, to advance the best
interests of the Company. At January 31, 1998, a total of 176 eligible employees
elected to participate in the Plan with total payroll deductions at that date of
$407,000. Purchases totaling 90,000 shares for $627,700 and 48,500 shares for
$406,500 were exercised at July 31, 1997 and January 31, 1998 respectively.
There are 611,500 remaining shares eligible for purchase under the Plan.
 
STOCK-BASED COMPENSATION
 
    The Company has adopted the disclosure-only provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." Accordingly, no compensation cost has
been recognized in the results of operations

</TABLE>
 
    Note: Diluted earnings per share is presented as equal to or less than basic
earnings per share.
 
    Using the Black-Scholes valuation model, the per share weighted-average fair
value of stock options granted during the fiscal years ended January 31, 1998,
1997, and 1996 was $4.62, $4.71, and $3.88, respectively.
 
    The pro forma effect on the Company's net income and basic earnings per
share for fiscal 1998, 1997, and 1996 is not representative of the pro forma
effect in future years. The pro forma effect does not take into consideration
compensation expense related to grants made prior to fiscal 1996 or additional
grants in future years which are anticipated. The fair value of each option is
estimated on the date of grant using the Black-Scholes option-pricing model with
the following weighted-average assumptions used for grants made in fiscal 1998:
dividend yield of 0%; expected volatility of 41.9%; risk-free interest rate of
7.0%. The following weighted-average assumptions were used for grants made in
fiscal 1997: dividend yield of 0%; expected volatility of 42.0%; risk-free
interest rate of 7.5%. The following weighted average assumptions were used for
grants made in fiscal 1996: dividend yield of 4.5%; expected volatility of
28.0%; risk-free interest rate of 7.5%.
 
    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options. The Company's employee stock options have
characteristics significantly different from those of traded options, such as
vesting restrictions and extremely limited transferability. In addition, the
assumptions used in option valuation models (see above) are highly subjective,
particularly the expected stock price volatility of the underlying stock.
Because changes in these subjective input assumptions can materially affect the
fair value estimate, in management's opinion the existing models do not provide
a reliable single measure of the fair value of its employee stock options.

</TABLE>
 
    The combined annual rental cost for facilities and various equipment under
operating leases approximated $5,645,000 in fiscal 1998, $5,340,000 in fiscal
1997, and $5,310,000 in fiscal 1996. In most cases management expects that in
the normal course of business, leases will be renewed or replaced by others.
 
    The Company has an agreement with its principal bank for a $15,000,000
unsecured line of credit at the prevailing prime rate. Borrowings under the line
are subject to certain restrictive covenants. This line of credit agreement
expires August 31, 2000. The line was unused at January 31, 1998 and January 31,
1997.
 
    At January 31, 1998, the Company had a forward exchange contract maturing in
less than one month, to exchange deutsche marks for U.S. dollars in the amount
of $1,172,000. The unrealized gain at January 31, 1998 was immaterial.
 
NOTE 14: SHAREHOLDERS' EQUITY
 
    In September 1988, the Company distributed to common shareholders one right
for each outstanding share of Common Stock. Each right entitles the holder to
purchase one-half share of Common Stock at an exercise price of $50 subject to
adjustment. The rights were attached to all Common Stock certificates and no
separate right certificate will be distributed.
 
    The rights, which do not have any shareholder rights, including voting or
dividend rights, will expire on September 19, 1998 unless earlier redeemed by
the Company prior to expiration at a price of $.01 per right. The rights
automatically transfer with a transfer of Common Stock until the time they
become exercisable, which happens when certain specified events occur. If the
rights become exercisable, they entitle the holders thereof to purchase stock or
other property of the Company at a reduced price, subject to certain other
provisions of the plan. At January 31, 1998, approximately 6,811,000 shares of
Common Stock were reserved for issuance in connection with these rights.
 
    The debentures issued by the Company have a feature that allows the holder
to convert the debentures to Common Stock of the Company at a conversion price
of $15.15 per share. At January 31, 1998, approximately 3,734,000 shares were
reserved for issuance upon conversion of debentures.

diluted earnings per share because the options' exercise price was greater than
the average market price of the common shares and, therefore, the effect would
be anitdilutive.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
To the Board of Directors and Stockholders of
  The MacNeal-Schwendler Corporation
 
    We have audited the accompanying consolidated balance sheets of The
MacNeal-Schwendler Corporation as of January 31, 1998 and 1997, and the related
consolidated statements of income, shareholders' equity, and cash flows for each
of the three years in the period ended January 31, 1998. Our audits also
included the financial statement schedule listed in the Index at Item 14 (a).
These financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of The
MacNeal-Schwendler Corporation at January 31, 1998 and 1997, and the
consolidated results of its operations and its cash flows for each of three
years in the period ended January 31, 1998, in conformity with generally
accepted accounting principles. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects the
information set forth therein.
