is subject to risks and uncertainties.  Various important factors, including but
not limited to those discussed herein, may cause the Company's future results to
differ materially from those projected in any forward-looking statement.
Important information about the basis for those assumptions is contained in
"Important Factors Regarding Future Results" included in Item 7, "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
incorporated by reference to pages 10 through 19 of the Company's 1998 Annual
Report to Stockholders.  All information presented is as of December 31, 1998
unless otherwise indicated.
                                     PART I
                                        
ITEM 1: BUSINESS

ANSYS, Inc. develops, markets and supports software solutions for design
analysis and optimization. Engineering analysts and design engineers use the
Company's software to accelerate product time to market, reduce production
costs, improve engineering processes and optimize product quality and safety for
a variety of manufactured products. The ANSYS(R) product family features open,
flexible architecture that permits easy integration and collaboration within
customers' enterprise-wide engineering systems.

Since its founding in 1970 as Swanson Analysis Systems, Inc. ("Swanson
Analysis"), the Company has become a technology leader in the market for
computer-aided engineering ("CAE") analysis software. The Company has long-
standing relationships with customers in many industries, including automotive,
aerospace, consumer goods and electronics. Using the Company's products,
engineers can construct computer models of structures, compounds, components or
systems to simulate performance conditions and physical responses to varying
levels of stress, pressure, temperature and velocity. This helps reduce the time
and expense of physical prototyping and testing.

The Company's product line ranges from ANSYS/Multiphysics, a sophisticated
multi-disciplinary CAE tool for engineering analysts, to its DesignSpace(R)
products, innovative computer-aided design ("CAD")-integrated design
optimization products for design engineers.  The Company's individual design and
analysis software programs, all of which are included in the ANSYS/Multiphysics
program, are available as subsets or standalone products. The Company's
multiphysics products, and maintenance sold in connection with those products,
comprise the core of its business and accounted for a substantial portion of the
Company's revenue in 1998, 1997 and 1996.  The Company's CAD integration
products provide design optimization tools for use directly within a particular
CAD product.  CAD integration products are accessed from the graphical user
interface of, and operate directly on the geometry produced within, the CAD
product.  The output from these programs may be read into any of the products in
the ANSYS product family. The Company's product family features a unified
database, a wide range of analysis functionality, a consistent, easy-to-use
graphical user interface, support for multiple hardware platforms and operating
systems (including Windows 95, Windows NT and UNIX), effective user
customization tools and integration with leading CAD systems. The Company's
products are developed using the Company's ISO 9001-certified quality system.

The Company markets its products principally through its global network of 35
independent regional ANSYS Support Distributors ("ASDs"), which have 67 offices
in 26 countries.


PRODUCT DEVELOPMENT

The Company makes significant investments in research and development and
emphasizes accelerated new product releases. The Company's product development
strategy centers on ongoing development and innovation of new technologies to
increase productivity and provide solutions that customers can integrate into
enterprise-wide

                                       2
<PAGE>
 
engineering systems. The Company's product development efforts focus on
extensions of the ANSYS product family with new functional modules, further
integration with CAD products and the development of new products based on
object-oriented technology. The Company's products run on the most widely used
engineering computing platforms and operating systems, including Windows 95,
Windows NT and most UNIX workstations, as well as on supercomputers such as the
Cray.

During 1998, the Company achieved the following with respect to major product
development activities and releases:

 .   The release of ANSYS 5.5, a new and enhanced version of the Company's
    flagship multiphysics product, and all component products. Major
    enhancements in this release include lower and higher order flexible-to-
    flexible contact; increased solution power for highly nonlinear structural
    analysis; new turbulence models for computational fluid dynamics; nonlinear
    harmonic analysis for electromagnetic applications; and topological
    optimization.

 .   ANSYS/ProFEA and ANSYS Connection for Pro/ENGINEER enhancement releases were
    available subsequent to Parametric Technology Corporation's ("Parametric
    Technology") release of its new versions of Pro/ENGINEER. These products
    enable users to access Pro/ENGINEER geometry directly from ANSYS products.

 .   The release of commercial versions of DesignSpace 4.0.  These products are
    developed using a C++ object-oriented product development environment . The
    current release of the DesignSpace products provides expanded functionality
    to associatively support geometry created in Mechanical Desktop, SolidWorks
    and Unigraphics, and support solid models created in any ACIS or Parasolid
    modeling CAD program. The software allows engineers to quickly and easily
    simulate design performance and provides tighter integration between design
    and analysis, as well as enhanced solving capabilities.

The Company's total research and development expense was $11.6 million, $11.0
million and $9.8 million in 1998, 1997 and 1996 or 20.6%, 21.8% and 20.8% of
total revenue, respectively.  As of December 31, 1998, the Company's product
development staff consisted of 106 full time employees, most of whom hold
advanced degrees and have industry experience in engineering, mathematics,
computer science or related disciplines.

The Company uses multi-functional teams to develop its products and develops
them simultaneously on multiple platforms to reduce subsequent porting costs. In
addition to developing source code, these teams create and perform highly
automated software verification tests; develop on-line documentation and help
for the products; implement development enhancement tools, software
configuration management and product licensing processes; and conduct regression
tests of ANSYS products for all supported platforms.

PRODUCT QUALITY

During 1998, the Company continued to maintain ISO 9001 certification for its
quality system. This standard applies to all of the Company's commercial
software products and covers all product-related activities, from establishing
product requirements to customer service practices and procedures.

In accordance with the ISO 9001 certification for its quality system, the
Company's employees perform all product development and support tasks according
to predefined quality plans, procedures and work instructions. These plans
define for each project the methods to be used, the responsibilities of project
participants and the quality objectives to be met.  To ensure that the Company
meets or surpasses the IS0 9001 standards, the Company establishes quality plans
for all products and services, subjects product designs to multiple levels of
testing and verification, and selects development subcontractors in accordance
with processes established under the Company's quality system.

SALES AND MARKETING

The Company distributes its multiphysics products and services primarily through
its global ASD network. This network provides the Company with a cost-effective,
highly specialized channel of distribution and technical support.  Approximately
82% of the Company's revenue in 1998 was derived through the ASDs.

At December 31, 1998, the ASD network consisted of 35 independent distributors
in 67 locations in 26 countries, including 16 in North America, 8 in Europe and
11 throughout the Asia-Pacific region and the remainder of the world. The ASDs
sell ANSYS and DesignSpace products to new customers, expand installations
within the existing customer base, offer training and consulting services and
provide the first line of ANSYS technical support. The Company's ASD
certification process helps to ensure that each ASD has the ongoing capacity to
adequately represent the Company's product line and provide an acceptable level
of training, consultation and support.

The Company also has a sales management infrastructure in place to work with the
ASDs to develop a more enterprise-wide focused sales approach, to implement a
worldwide major account strategy and to provide additional support in strategic
locations through the presence of direct sales offices.  As of December 31,
1998, the Company's sales management organization consisted of a North American
Vice President of Sales, supported by four Regional Sales Directors and four
Major Account Representatives; an International Vice President of Sales and a
Regional Sales Director; and a European Managing Director supported by three
Regional Sales Directors and one Strategic Account Manager.

During 1998, the Company continued to expand its direct global sales
infrastructure through the establishment of additional regional sales offices in
Houston, Texas; Minneapolis, Minnesota; New England and China.  The Company also
continued to invest in its previously established strategic sales offices in the
United Kingdom, Michigan and Japan.  In total, these offices employ 26 persons
who are responsible for the implementation of sales and marketing initiatives
and administration in those geographic areas designed to support the Company's
overall revenue growth and market share expansion strategies.

During fiscal 1998, the Company also continued to expand the reseller channel
for both its ANSYS and DesignSpace products. This channel compliments the ASD
network by establishing a broader user base for the Company's  products and
services.  As of December 31, 1998, the Company had signed agreements with 172
resellers. All resellers are required to meet the Company's standards for sales
and customer support by ensuring they have appropriately trained marketing and
technical personnel.

The Company's products have an installed base of approximately 53,000 seats at
commercial sites and approximately 97,000 seats at university sites worldwide.
The Company's products are utilized by organizations ranging in size from small
consulting firms to the world's largest industrial companies.  No single
customer accounted for more than 1.4% of the Company's revenue in fiscal 1998.

Information with respect to foreign and domestic revenue may be found in Note 15
to the Consolidated Financial Statements and the section entitled " Management's
Discussion and Analysis of Financial Condition and Results of Operations" of the
Annual Report to Stockholders for the year ended December 31,1998 ("1998 Annual
Report to Stockholders"), which financial statements are included in Exhibit
13.1 to this Annual Report on Form 10-K and incorporated herein by reference.

Additionally, countries in the Asia-Pacific region, including Japan, have
experienced weaknesses in their currency, banking and equity markets throughout
most of 1998.  To the extent that such trends continue, these economic
weaknesses could adversely affect consumer demand for the Company's products and
ultimately the Company's financial position or results of operations.


STRATEGIC ALLIANCES AND MARKETING RELATIONSHIPS

The Company has established and continues to pursue strategic alliances with
advanced technology suppliers and marketing relationships with hardware vendors,
specialized application developers and CAD providers. The Company believes these
relationships allow it to accelerate the incorporation of advanced technology
into the ANSYS product family, gain access to important new markets, expand the
Company's sales channel, develop specialized product applications and provide
direct integration with leading CAD systems.

                                       4
<PAGE>
 
One such example is the Company's software license agreement with Livermore
Software Corporation under which Livermore has provided LS/DYNA software for
explicit dynamics solutions used in applications such as crash test simulation
in the automotive and other industries. Under this arrangement, Livermore
assists in the integration of the LS/DYNA software with the Company's pre- and
postprocessing capabilities and provides updates and problem resolution in
return for a share of revenue from sales of ANSYS/LS-DYNA.

The Company has technical and marketing relationships with leading CAD vendors,
such as Parametric Technology, Autodesk, Computervision, Intergraph,
EDS/Unigraphics, SolidWorks and Dassault Systemes, to provide direct links
between the vendors' CAD packages. These links facilitate the transfer of
electronic data models between the CAD system and ANSYS products. During 1998,
the Company also entered into a joint marketing and development agreement with
Tanner EDA, a leader in PC-based design software for MicroElectro Mechanical
Systems, aimed at accelerating the growth of microsystem product design to
deliver a new generation of design and analysis capabilities.

The Company has established relationships with leading suppliers of computer
hardware, including Hewlett-Packard, Compaq, Silicon Graphics/Cray, Sun
Microsystems, Intergraph, IBM, Dell and Intel. The relationships typically
provide the Company with joint marketing and advertising, Internet links with
the hardware partner's home page and reduced equipment costs.

The Company's Enhanced Solution Provider Program actively encourages specialized
developers of niche software solutions to use ANSYS as a development platform
for their applications.  Examples of companies using the products include COMET
Acoustics, which uses ANSYS/PrepPost/TM/ to run its acoustic solver for the
automobile industry; AC Technologies, which provides an interface to ANSYS in
connection with its plastic injection mold flow analysis product;  Materials
Engineering Research Laboratory, Ltd., which offers a bundled product consisting
of their FLEXPAC solver, and ANSYS/PrepPost/TM/ that enables users to make
fatigue calculations an integral part of their design process for a wide range
of elastomeric components. In most cases, the sale of the Enhanced Solution
Providers' products is accompanied by the sale of an ANSYS product.


COMPETITION

The CAD, CAE and computer-aided manufacturing ("CAM") markets are intensely
competitive. In the traditional CAE market, the Company's primary competitors
include MacNeal-Schwendler Corporation, Hibbitt, Karlsson and Sorensen, Inc. and
MARC Analysis Research Corporation. The Company also faces competition from
smaller vendors of specialized analysis applications in fields such as
computational fluid dynamics. In addition, certain integrated CAD suppliers such
as Parametric Technology, Structural Dynamics Research Corporation and Dassault
Systemes provide varying levels of design analysis and optimization and
verification capabilities as part of their product offerings.

The entrance of new competitors would likely intensify competition in all or a
portion of the overall CAD, CAE and CAM markets. Some of the Company's current
and possible future competitors have greater financial, technical, marketing and
other resources than the Company, and some have well-established relationships
with current and potential customers of the Company. It is also possible that
alliances among competitors may emerge and rapidly acquire significant market
share or that competition will increase as a result of software industry
consolidation. Increased competition may result in price reductions, reduced
profitability and loss of market share, any of which would materially adversely
affect the Company's business, financial condition and results of operations.

The Company believes that the principal competitive factors affecting its market
include ease of use; flexibility; quality; ease of integration into CAD systems;
file compatibility across computer platforms; range of supported computer
platforms; performance; price and cost of ownership; customer service and
support; company reputation and financial viability; and effectiveness of sales
and marketing efforts. Although the Company believes that it currently competes
effectively with respect to such factors, there can be no assurance that the
Company will be able to maintain its competitive position against current and
potential competitors. There also can be no assurance that CAD software
companies will not develop their own analysis software, acquire analysis
software from companies other than the Company or otherwise discontinue their
relationships with the Company. If any of these events occur, the Company's
business, financial condition and results of operations could be materially
adversely affected.

PROPRIETARY RIGHTS AND LICENSES

The Company regards its software as proprietary and relies on a combination of
trade secret, copyright and trademark laws, license agreements, nondisclosure
and other contractual provisions, and technical measures to protect its
proprietary rights in its products. The Company distributes its ANSYS software
under software license agreements that grant customers nonexclusive licenses for
the use of the Company's products, which are typically nontransferable. Although
the Company distributes its products primarily through the ASDs, licenses of the
Company's products are directly between the Company and end users. Use of the
licensed software is usually restricted to the customer's internal operations on
designated computers at specified sites unless the customer obtains a site
license for its use of the software. Software and hardware security measures are
also employed to prevent unauthorized use of the Company's software, and the
licensed software is subject to terms and conditions prohibiting unauthorized
reproduction of the software. Customers may either purchase a paid-up perpetual
license of the technology with the right to purchase annually ongoing
maintenance, support and updates, or may lease the product on an annual basis
for a fee which includes the license, maintenance, support and upgrades.

For certain software such as DesignSpace and ANSYS/ED, the Company primarily
relies on "shrink-wrapped" licenses that are not signed by licensees.  The
enforceability of these types of agreements under the laws of certain
jurisdictions is uncertain.

The Company also seeks to protect the source code of its software as a trade
secret and as unpublished copyrighted work. The Company has obtained a federal
trademark protection for ANSYS and DesignSpace. The Company has also obtained
trademark registrations of ANSYS and DesignSpace in a number of foreign
countries and is in the process of seeking such registration in other foreign
countries.

Most employees of the Company have signed a Covenant Agreement under which they
have agreed not to disclose trade secrets or confidential information, or to
engage in or become connected with any business which is competitive with the
Company anywhere in the world while employed by the Company (and in some cases
for specified periods thereafter), and that any products or technology created
by them during their term of employment is the property of the Company. In
addition, the Company requires all ASDs to enter into agreements not to disclose
the Company's trade secrets and other proprietary information.

Despite these precautions, there can be no assurance that misappropriation of
the Company's technology will not occur. Further, there can be no assurance that
copyright and trade secret protection will be available for the Company's
products in certain countries, or that restrictions on competition will be
enforceable.

The software development industry is characterized by rapid technological
change. Therefore, the Company believes that factors such as the technological
and creative skills of its personnel, new product developments, frequent product
enhancements, name recognition and reliable product maintenance are more
important to establishing and maintaining a technology leadership position than
the various legal protections of its technology which may be available.

The Company is not aware that any of its products infringe upon the proprietary
rights of third parties. There can be no assurance, however, that third parties
will not claim in the future such infringement by the Company or its licensors
or licensees with respect to current or future products. The Company expects
that software product developers will increasingly be subject to such claims as
the number of products and competitors in the Company's market segment grow and
the functionality of products in different market segments overlaps. Any such
claims, with or without merit, could be time-consuming, result in costly
litigation, cause product shipment delays or require the Company to enter into
royalty or licensing agreements. Such royalty or licensing agreements, if
required, may not be available on terms acceptable to the Company.

BACKLOG

The Company generally ships its products within 30 days after acceptance of an
order and execution of a software license agreement.  Accordingly, the Company
does not believe that its backlog at any particular point in time is indicative
of future sales levels.

                                       6

EMPLOYEES

As of  December 31, 1998, the Company had 260 full time employees. At that date,
there were also approximately five contract personnel and co-op students
providing ongoing development services and technical support. The Company
believes that its relationship with its employees is good.


ITEM 2: PROPERTIES

The Company's executive offices and those related to product development,
marketing, production and administration are located in a 107,000 square foot
office facility in Canonsburg, Pennsylvania, which is leased for an annual rent
of approximately $1,227,000.  The Company also leases office space in various
locations throughout the world.  ANSYS's  subsidiaries lease office space for
their operations.  The Company owns substantially all equipment used in its
facilities.  Management believes that its facilities allow for sufficient space
to support not only its present needs, but also allow for expansion and growth
as the business may require in the foreseeable future.


ITEM 3: LEGAL PROCEEDINGS

The Company is subject to various legal proceedings from time to time that arise
in the ordinary course of business activities.  Each of these matters is subject
to various uncertainties, and it is possible that these matters may be resolved
unfavorably to the Company.


ITEM 4: SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matters were submitted to a vote of security holders during the fourth

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

REVENUE. The Company's total revenue increased 11.9% in 1998 to $56.6 million
from $50.5 million in 1997. The increase in total revenue in 1998 as compared to
1997 was attributable principally to an increase in revenue from renewals and
sales of noncancellable annual leases, for which a portion of the annual license
fee is recognized as paid-up revenue upon renewal or inception of the lease,
while the remaining portion is recognized ratably over the remaining lease
period. This increase, which was partially offset by a decrease in monthly lease
license revenue, as described below, was due, in part, to the active sales and
licensing of noncancellable annual leases to existing and new lease customers.
The increase in total revenue in 1998 was also attributable to increased
maintenance and service revenue, which resulted from broader customer usage of
maintenance and support services and the Company's continued emphasis on the
marketing and promotion of these services.

  Software license revenue totaled $35.5 million in 1998 as compared to $35.1
million in 1997, an increase of 1.1%. The increase resulted principally from an
increase in revenue from renewals and sales of noncancellable annual leases and,
to a lesser extent, an increase in sales of paid-up licenses in international
markets. Revenue from the sale of paid-up licenses and the portion of
noncancellable annual leases classified as paid-up revenue increased 29.6% in
1998 to $29.2 million from $22.6 million in 1997. This increase was partially
attributable to a refinement of management's estimate relative to the allocation
of noncancellable annual lease revenue between paid-up and maintenance revenue.
The refinement, which management believes more accurately reflects the Company's
current pricing and business practices, resulted in a net revenue increase of
approximately $1.3 million during 1998. The increase in software license revenue
was substantially offset by a 50.3% decrease in monthly lease license revenue to
$6.2 million in 1998 from $12.5 million in 1997. This decrease was attributable
to both an increase in the renewal of existing monthly leases as noncancellable
annual leases and, to a much lesser extent, the conversion of certain existing
leases to paid-up licenses.

  Maintenance and service revenue increased from $15.5 million in 1997 to $21.1
million in 1998. Contributing to the increase were broader customer usage of
maintenance and support services and the Company's increased emphasis on
marketing and promoting these services, as well as an increase in the renewal
and sale of noncancellable annual leases.

  Of the Company's total revenue in 1998, approximately 54.4% and 45.6%,
respectively, were attributable to international and domestic sales, as compared
to 53.2% and 46.8%, respectively, in 1997.

COST OF SALES AND GROSS PROFIT. The Company's total cost of sales increased
16.7% to $6.1 million, or 10.7% of total revenue, in 1998 from $5.2 million, or
10.3% of total revenue, in 1997. The Company's cost of sales for software
license revenue increased 20.2% in 1998 to $3.4 million, or 9.6% of software
license revenue, from $2.8 million, or 8.1% of software license revenue, in
1997. The increase was due to additional headcount and related expenses,
increased salaries and higher costs associated with the printing of manuals,
packing supplies, media and royalty fees. The Company's cost of sales for
maintenance and service revenue totaled $2.7 million and $2.4 million, or 12.6%
and 15.3% of maintenance and service revenue, in 1998 and 1997, respectively.
The increase was primarily attributable to increases in salaries, benefits and
consulting fees as additional staff and consultants were added to support the
growth in global service revenue and related customer and ASD support needs. The
increases in cost of sales for both licenses and maintenance and services
discussed above were partially offset by lower pension and profit-sharing costs
resulting from plan amendments in fiscal 1998.

  As a result of the foregoing, the Company's gross profit increased 11.3% to
$50.5 million in 1998 from $45.3 million in 1997.

SELLING AND MARKETING. Selling and marketing expenses increased 11.0% in 1998 to
$13.1 million, or 23.2% of total revenue, from $11.8 million, or 23.4% of total
revenue, in 1997. The increase was principally the result of increased
consulting and sales support costs incurred in connection with supporting a
global sales and marketing infrastructure. Additionally, during 1998 the Company
experienced an increase in expenses directly associated with its worldwide
users' conference and increased expenses associated with strategic office
locations in the United Kingdom, China and Japan. The Company anticipates that
it will continue to make significant investments in its global sales and
marketing organization to strengthen its competitive position and to support its
worldwide sales channels and marketing strategies. These increases were
partially offset by lower sales commissions and pension and profit-sharing
costs.

RESEARCH AND DEVELOPMENT. Research and development expenses increased 5.7% in
1998 to $11.6 million, or 20.6% of total revenue, from $11.0 million, or 21.8%
of total revenue, in 1997. The increase resulted primarily from additional
headcount and related expenses, higher salaries and increased consulting costs
associated with the releases of ANSYS 5.5 and DesignSpace 4.0, as well as
increased computer software costs and hardware-related depreciation expense as
the Company continued to invest in software and hardware tools used to develop
and enhance the Company's products. These increases were partially offset by a
reduction in pension and profit-sharing costs. The Company has traditionally
invested significant resources in research and development activities and
intends to continue to make significant investments in the future.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


AMORTIZATION. Amortization expense was $884,000 in 1998 and $2.8 million in
1997. The decrease was attributable to certain intangible assets, including
goodwill and capitalized software, becoming fully amortized during the first
quarter of 1997.

GENERAL AND ADMINISTRATIVE. General and administrative expenses increased 7.2%
in 1998 to $9.6 million, or 17.0% of total revenue, from $9.0 million, or 17.8%
of total revenue, in 1997. The increase was primarily attributable to an
increase in salaries and headcount and related expenses, as well as higher
depreciation expense attributable to computer hardware and software. These
increases resulted as the Company continued to add internal information
technology, financial and administrative resources to support its global
operations and infrastructure. These increases were partially offset by
decreases in both pension and profit-sharing costs, as well as bad debt expense.

OTHER INCOME. Other income increased to $1.9 million in 1998 as compared to
$912,000 in 1997. The increase was primarily attributable to higher interest-
bearing cash and short-term investment balances in 1998.

INCOME TAX PROVISION. The Company's effective rate of taxation was 33.8% in 1998
as compared to 36.4% in 1997. The lower 1998 rate is primarily the result of a
full year of benefit related to the use of a foreign sales corporation that was
established in the fourth quarter of 1997. The effective rates in both 1998 and
1997 are less than the federal and state combined statutory rates due primarily
to the utilization of research and experimentation credits as well as the impact
of the foreign sales corporation.

NET INCOME. The Company's net income increased 53.4% to $11.3 million, or $.68
diluted earnings per share, in 1998 as compared to net income of $7.4 million,
or $.45 diluted earnings per share, in 1997. The weighted average common and
common equivalent shares used in computing diluted earnings per share were 16.6
million in 1998 compared with 16.5 million in 1997.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

REVENUE. The Company's total revenue increased 7.4% in 1997 to $50.5 million
from $47.1 million in 1996. The increase in total revenue in 1997 as compared to
1996 was attributable principally to an increase in revenue from renewals and
sales of noncancellable annual leases. The increase, which was partially offset
by decreases in monthly lease license revenue and paid-up license revenue, was
due, in part, to the active sales and licensing of noncancellable annual leases
to existing and new lease customers during 1997. The increase in total revenue
in 1997 was also attributable to increased maintenance revenue, which resulted
from broader customer usage of maintenance and support services and the
Company's continued emphasis on marketing its maintenance services.

  The comparison of the Company's revenue in 1997 and 1996 is affected by the
Company's change in licensing and sales practices as they related to leases.
Beginning in the third quarter of 1996, the Company began to promote sales and
renewals of noncancellable annual leases, for which a portion of the annual
license fee is recognized as paid-up revenue upon renewal or inception of the
lease, while the remaining portion is recognized as maintenance revenue ratably
over the remaining lease period. Prior to the third quarter of 1996, the Company
recorded all revenue from lease licenses as license revenue, as earned, because
the underlying lease agreements contained provisions which allowed the customer
to cancel the lease with 30 days notice. The effect of this change generally was
to increase paid-up revenue attributable to sales and renewals of leases and to
increase maintenance revenue for 1997 relative to 1996, while resulting in a
corresponding decrease in monthly lease license revenue. Had this change not
been initiated, software license revenue would have been reported as $37.9
million in 1997 as compared to $37.4 million in 1996, while maintenance and
service revenue would have been reported as $12.3 million and $9.6 million in
1997 and 1996, respectively.

  Software license revenue decreased 5.2% in 1997 to $35.1 million from $37.0
million in 1996, resulting principally from existing monthly lease customers
shifting to noncancellable annual leases in connection with the renewals of
their leases, thereby reducing the portion of their lease fees characterized as
license revenue, as described above. The decrease was also due to a decrease in
the sale of paid-up licenses in the domestic market as compared to the prior
year, as paid-up license revenue for 1996 reflected the recognition of
substantial revenue from several large contracts. The foregoing decreases in
monthly lease and paid-up revenue were partially offset by an increase in
revenue from renewals and sales of leases as noncancellable annual leases, as
described above. Revenue from the sale of paid-up licenses, excluding the
portion of noncancellable annual leases classified as paid-up revenue, decreased
4.2% in 1997 to $18.6 million from $19.4 million in 1996. The Company also
experienced a 27.9% decrease in monthly lease license revenue to $12.5 million
in 1997 from $17.4 million in 1996. This decrease was attributable to an
increase in the renewal of existing leases as noncancellable annual leases, as
well as the conversion of certain existing lease licenses to paid-up licenses in
1997. The total revenue recognized from monthly and noncancellable annual leases
was $19.3 million and $18.0 million in 1997 and 1996, respectively, of which
$2.8 million and $400,000 were classified as maintenance revenue in 1997 and
1996, respectively. Maintenance and service revenue, excluding the portion of
noncancellable annual leases recognized as maintenance revenue, increased 31.6%
in 1997 to $12.7 million from $9.6 million in 1996 as a result of broader
customer usage of maintenance and support services, the Company's increased
emphasis on marketing these services as well as an increase in the renewal and
sale of noncancellable annual leases.

  Of the Company's total revenue in 1997, approximately 53.2% and 46.8%,
respectively, were attributable to international and domestic sales as compared
to 49.4% and 50.6%, respectively, in 1996.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


COST OF SALES AND GROSS PROFIT. The Company's total cost of sales decreased 3.5%
to $5.2 million in 1997 from $5.4 million in 1996, representing 10.3% and 11.4%
of total revenue, respectively. The Company's cost of sales for software license
revenue decreased 7.1% in 1997 to $2.8 million, or 8.1% of software license
revenue, from $3.1 million, or 8.2% of software license revenue, in 1996. The
decrease was due primarily to a reduction in costs related to manuals, packing
supplies and media. The Company's cost of sales for maintenance and service
revenue remained relatively stable at $2.4 million and $2.3 million, or 15.3%
and 23.2% of maintenance and service revenue, for 1997 and 1996, respectively.

  As a result of the foregoing, the Company's gross profit increased 8.8% to
$45.3 million in 1997 from $41.7 million in 1996.

SELLING AND MARKETING. Selling and marketing expenses increased 21.7% in 1997 to
$11.8 million, or 23.4% of total revenue, from $9.7 million, or 20.7% of total
revenue, in 1996. This planned growth was attributable principally to increased
personnel costs, including costs associated with increased headcount and
compensation expenses related to the ongoing establishment of a global sales and
marketing organization, as well as the establishment of strategic offices in the
United Kingdom, Michigan and Japan in 1997.

RESEARCH AND DEVELOPMENT. Research and development expenses increased 12.3% in
1997 to $11.0 million, or 21.8% of total revenue, from $9.8 million, or 20.8% of
total revenue, in 1996. This increase resulted primarily from employment of
additional staff and independent contractors to develop and enhance the
Company's products, including a dedicated team working on the development of the
Company's DesignSpace products. The increase was partially offset by a decrease
in equipment lease expense.

AMORTIZATION. Amortization expense was $2.8 million in 1997 and $10.8 million in
1996. The decrease was attributable to the full amortization of certain of the
intangible assets which resulted from the acquisition of the Company in 1994
("1994 Acquisition"), including goodwill and capitalized software, which became
fully amortized in the first quarter of 1997.

GENERAL AND ADMINISTRATIVE. General and administrative expenses increased 16.5%
in 1997 to $9.0 million, or 17.8% of total revenue, from $7.7 million, or 16.4%
of total revenue, in 1996. The increase is primarily attributable to expenses
incurred to increase the allowance for doubtful accounts and an increase in
legal fees related to a dispute regarding the expiration of an ASD distribution
agreement. Additionally, the Company added internal legal and financial
resources to support the operations of a publicly owned company, which were
offset by a significant reduction in outside labor and consulting fees.

INTEREST. Interest expense, which was $1,000 in 1997, totaled $1.7 million in
1996. This decrease was attributable to the early repayment of all outstanding
debt related to the 1994 Acquisition with the net proceeds from the Company's
initial public offering in June 1996.

OTHER INCOME. Other income increased in 1997 to $912,000 as compared to $611,000
for 1996. This increase was primarily attributable to higher interest-bearing
cash and investment balances in 1997.

INCOME TAX PROVISION. The Company's effective rate of taxation was 36.4% in
1997, as compared to 37.0% in 1996. These percentages are less than the federal
and state combined statutory rates due primarily to the utilization of research
and experimentation credits as well as the use of a foreign sales corporation
which was established in the fourth quarter of 1997.

NET INCOME. The Company's net income totaled $7.4 million in 1997 as compared to
net income before extraordinary item of $1.6 million in 1996. The Company's net
income including the extraordinary item in 1996 was $1.3 million. Diluted
earnings per share was $.45 in 1997 as compared to diluted earnings per share,
after extraordinary item, of $.07 in 1996. The increase in diluted earnings per
share was attributable to the increase in net income, as well as the elimination
of the preferred stock dividends due to the redemption of the redeemable
preferred stock, which occurred at the time of the Company's initial public
offering in June 1996. The weighted average shares used in computing net income
per diluted common share amounts increased to 16.5 million in 1997 from 14.9
million in 1996 primarily as a result of the initial public offering.

  Effective December 31, 1997, the Company adopted Statement of Financial
Accounting Standards No. 128, "Earnings per Share," issued in February 1997, and
has restated prior periods in accordance with this pronouncement.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


LIQUIDITY AND CAPITAL RESOURCES

  As of December 31, 1998, the Company had cash, cash equivalents and short-term
investments totaling $42.7 million and working capital of $38.0 million, as
compared to cash, cash equivalents and short-term investments of $27.8 million
and working capital of $23.8 million at December 31, 1997. The short-term
investments are generally investment grade and liquid-type, which allows the
Company to minimize interest rate risk and to facilitate liquidity in the event
an immediate cash need arises.

  The Company's operating activities provided cash of $15.6 million in 1998,
$12.7 million in 1997 and $13.5 million in 1996. The increase in cash generated
from operations in 1998 as compared to 1997 is primarily the result of increased
earnings after the effect of non-cash expenses such as depreciation,
amortization and deferred income taxes. The decrease in cash generated from
operations in 1997 as compared to 1996 is the result of fluctuations within the
individual components of working capital, as well as a decrease in earnings
after the effect of depreciation and amortization. Net cash generated by
operating activities provided sufficient resources to fund increased headcount
and capital needs to support the Company's expansion of its global sales support
network, its continued investment in research and development activities and the
addition of financial and administrative resources during 1998.

  Cash used in investing activities was $23.5 million in 1998, $16.1 million in
1997 and $2.6 million in 1996. The Company's use of cash for investing
activities in 1998 and 1997 was primarily related to the purchase of short-term
investments, and to a lesser extent the purchase of computer software, hardware
equipment and furniture for the corporate office facility, while the use of cash
in 1996 was substantially related to capital expenditures. The Company expects
to spend approximately $2.2 million for capital expenditures in 1999,
principally for the acquisition of computer hardware and software to support the
continued growth of the Company's development activities and expansion of its
global sales and support infrastructure.

  Financing activities provided cash of $453,000 in 1998 and $336,000 in 1997,
and used cash of $1.9 million in 1996. Cash provided from financing activities
in 1998 and 1997 was substantially related to proceeds from the issuance of
common stock under employee stock purchase and option plans and the reissuance
of treasury shares. Cash provided from financing activities in 1996 was due
primarily to the net proceeds of $41.0 million received from the Company's
initial public offering on June 25, 1996. These proceeds were more than offset
by the repayment of the indebtedness incurred to finance the acquisition of the
Company in 1994, payment of related unpaid interest, the redemption of
redeemable preferred stock and accumulated dividends thereon, issued in
connection with such acquisition.

  The Company believes that existing cash and cash equivalent balances together
with cash generated from operations will be sufficient to meet the Company's
working capital and capital expenditure requirements through at least the next
fiscal year. The Company's cash requirements in the future may also be financed
through additional equity or debt financings. There can be no assurance that
such financings can be obtained on favorable terms, if at all.

MANAGEMENT'S ASSESSMENT OF THE YEAR 2000

  The year 2000 ("Y2K") problem refers to the inability of software to process
date information later than December 31, 1999. Date codes in many software
programs are abbreviated to allow only two digits for the year. Software with
date-sensitive functions that is not year 2000 compliant may not be able to
distinguish whether "00" means 1900 or 2000. When that happens, some software
will not work at all and other software will suffer critical calculation and
other processing errors. Hardware and other products with embedded chips may
also experience problems.

SOFTWARE PRODUCTS. The Company provides analysis and engineering software for
optimizing the design of new products. The functionality offered by these
products is generally not date dependent and consequently the Company's software
products have minimal date sensitivities or dependencies.

  The current releases of the Company's ANSYS and DesignSpace product lines are
Y2K Compliant, as defined below. Management believes that essentially 100% of
its 1998 license and service revenue has been derived from the sale of Y2K
Compliant products and services. The Company defines "Y2K Compliant" as the
ability to meet the British Standards Institution DISC PD 2000-1: Year 2000
conformity requirements. This definition provides that Year 2000 conformity
shall mean that neither performance nor functionality is affected by dates prior
to, during or after the year 2000.

  The Company began shipping Y2K Compliant ANSYS products beginning in 1997 with
Release 5.4. The Company believes that versions of the ANSYS products shipped
between 1993 and 1996 should function after December 31, 1999. However, the
Company cannot make a definitive statement regarding these products because they
have not been tested on all platforms or on all versions of operating systems.
Consequently, the Company has advised its customers who may still be using these
older versions to (a) upgrade to later releases of the Company's software, and
(b) verify that their platforms and operating systems support the transition to
the year 2000. ANSYS products shipped prior to 1993 will not function after
December 31, 1999 and the Company has continually advised its customers to
upgrade such products to newer versions.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


  The Company began shipping Y2K Compliant DesignSpace products beginning in
1996 with release 2.0, with the exception that the report generator utility
contained in the DesignSpace product may or may not be Y2K Compliant. The report
generator extensively utilizes many Microsoft components whose Y2K compliance
has not yet been determined; consequently, the DesignSpace report generator
utility may or may not be Y2K Compliant.

  Some commentators have predicted significant litigation regarding Y2K
compliance issues, and the Company is aware of such lawsuits against other
software vendors. Because of the unprecedented nature of such litigation, it is
uncertain whether, or to what extent, the Company may be affected. However, at
this time the Company believes that the existence of earlier versions of its
products that are not Y2K Compliant is not likely to have a material adverse
effect on the Company's financial position or results of operations.

INTERNAL SYSTEMS. The Company has developed a Year 2000 Project Plan ("Y2K
Plan") that addresses both information technology ("IT") systems (i.e., business
systems and the software development environment) and other systems such as
elevators, building security and HVAC systems.

  The Y2K Plan includes five phases: 1) raising Company awareness, 2) a company-
wide system inventory, 3) criticality assessment, 4) implementation (including
remediation, upgrading and/or replacement of certain systems) and 5) compliance
certification testing. Phases 1-3 are complete. Phase 4 (implementation) and
Phase 5 (compliance certification testing) are underway in an iterative process
dependent on what may be found during compliance testing. The following graphs
present information on the Company's current overall status of the
implementation and compliance phases of the Y2K Plan, as well as information
regarding expected final testing completion dates. This information, provided in
these graphs, specifically relates to internal systems which have been
identified as high or critical importance during the criticality assessment of
the Y2K Plan.

COST OF YEAR 2000 COMPLIANCE EFFORTS. The Company has funded its Y2K Plan from
operating cash flows and has not separately accounted for related costs in the
past, partly because the responsibilities and costs are distributed throughout
the organization and represent a small percentage of total operating costs. The
Company's current estimate of total costs to the Company for achieving Y2K
compliance is approximately $500,000 over three years (1997 -- 2000), with about
two-thirds of those costs estimated to already have been incurred. Implementing
the Y2K Plan has caused some delays in other planned IT initiatives; however,
these delays have not had a material effect on the Company's operations. There
can be no assurance, however, that there will not be a delay in the completion
of the Y2K Plan. Such a delay could have a material adverse effect on future
results of operations. The Company may experience unforeseen problems and costs
related to Y2K compliance that could materially adversely affect the Company's
business, results of operations and financial condition.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


RISKS AND CONTINGENCIES. The Company has initiated the development of a
comprehensive Y2K contingency plan to address situations that may result if the
Company is unable to achieve Y2K readiness of its critical systems. The
contingency plan is expected to be completed during the second quarter of 1999.

THIRD PARTY RELATIONSHIPS. The Company has contacted its distributors and key
vendors regarding their Y2K compliance efforts. Although the Company has
received information from some of its distributors and vendors regarding their
Y2K compliance efforts, there can be no assurance that the Company will not
experience disruptions in its ability to conduct business because of Y2K
problems experienced by the Company's distributors or vendors. The Company has
no practical means to verify Y2K compliance of independent vendors who have not
yet responded. To the extent that its key distributors or vendors experience
problems relative to achieving Y2K compliance, the Company could suffer
unanticipated revenue losses.

  In addition, the Company does not currently have meaningful information
concerning the Y2K compliance status of its customers. As is the case with other
software companies, if significant numbers of the Company's current or future
customers fail to achieve Y2K compliance, or if they divert technology
expenditures away from those that were reserved for computer-aided engineering
("CAE") software to address Y2K compliance problems, the Company's business,
results of operations or financial condition could be materially adversely
affected.

QUALIFICATION. The Year 2000 discussion above contains various forward-looking
statements which represent the Company's beliefs or expectations regarding
future events. When used in the Year 2000 discussion, the words "believes,"
"expects," "estimates" and other similar expressions are intended to identify
forward-looking statements. Forward-looking statements include, without
limitation, the Company's expectations as to when it and its significant
distributors, customers and suppliers will complete the implementation and
compliance phases of the Y2K Plan, as well as its Year 2000 contingency plans;
its estimated costs related to the Y2K Plan; the effect of earlier versions of
the Company's products or Y2K problems experienced by key distributors, vendors
or customers; and the Company's belief that its internal systems and equipment
will be Y2K Compliant in a timely manner. All forward-looking statements involve
a number of risks and uncertainties that could cause the actual results to
differ materially from the projected results. Factors that may cause these
differences include, but are not limited to, the availability of qualified
personnel and other information technology resources, the ability to identify
and remediate all date-sensitive lines of code or to replace embedded chips in
affected systems or equipment, unanticipated delays or expenses related to
remediation and the actions of independent third parties with respect to Year
2000 problems.

  The statements in the previous section include "Year 2000 Readiness
Disclosures" within the meaning of the Year 2000 Information and Readiness
Disclosure Act of 1998.

CONVERSION TO THE EURO

  On January 1, 1999, eleven of the member countries of the European Union
established fixed conversion rates between their existing currencies and one
common currency, the euro. The legacy currencies will remain legal currency in
the participating countries during a transition period through January 1, 2002.
Beginning on this date, new euro-denominated currency will be issued and the
legacy currencies will be withdrawn from circulation.

  The Company is currently in the early stages of identifying and addressing
issues that may result from the euro conversion such as changes to information
systems to accommodate euro-denominated transactions, long-term competitive
implications and the exposure to market risk with respect to financial
instruments. Although our assessment of the impact of the euro conversion is not
yet complete, we do not currently believe that the conversion will have a
material adverse impact on the Company's financial position or results of
operations.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

  In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities," which defines derivatives, requires that all
derivatives be carried at fair value and provides for hedge accounting when
certain conditions are met. The Standard is effective for all fiscal quarters of
fiscal years beginning after June 15, 1999. The Company is currently in the
process of evaluating the prospective impact of Statement No. 133 on its
financial position and results of operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


IMPORTANT FACTORS REGARDING FUTURE RESULTS

  Information provided by the Company or its spokespersons, including
information contained in this Annual Report to Shareholders, may from time to
time contain forward-looking statements concerning projected financial
performance, market and industry segment growth, product development and
commercialization or other aspects of future operations. Such statements will be
based on the assumptions and expectations of the Company's management at the
time such statements are made. The Company cautions investors that its
performance (and, therefore, any forward-looking statement) is subject to risks
and uncertainties. Various important factors, including but not limited to the
following, may cause the Company's future results to differ materially from
those projected in any forward-looking statement.

POTENTIAL FLUCTUATIONS IN OPERATING RESULTS. The Company may experience
significant fluctuations in future quarterly operating results. Fluctuations may
be caused by many factors, including the timing of new product releases or
product enhancements by the Company or its competitors; the size and timing of
individual orders, including a fluctuation in the demand for and the ability to
complete large contracts; software errors or other product quality problems;
competition and pricing; customer order deferrals in anticipation of new
products or product enhancements; reduction in demand for the Company's
products; changes in operating expenses; changes in the mix of software license
and maintenance and service revenue; personnel changes; and general economic
conditions. A substantial portion of the Company's operating expenses is related
to personnel, facilities and marketing programs. The level of personnel and
related expenses cannot be adjusted quickly and is based, in significant part,
on the Company's expectation for future revenue. The Company does not typically
experience significant order backlog. Further, the Company has often recognized
a substantial portion of its revenue in the last month of a quarter, with this
revenue frequently concentrated in the last weeks or days of a quarter. During
certain quarterly periods, the Company has been dependent upon receiving large
orders of perpetual licenses involving the payment of a single up-front fee,
which could increase the volatility of the Company's revenue and profit from
period to period. More recently, the Company has also experienced an increase in
renewals and sales of noncancellable annual leases, for which a portion of the
annual license fee is recognized as paid-up revenue upon renewal or inception of
the lease. As a result, product revenue in any quarter is substantially
dependent on sales completed in the latter part of that quarter, and revenue for
any future quarter is not predictable with any significant degree of accuracy.

STOCK MARKET VOLATILITY. Market prices for securities of software companies have
generally been volatile. In particular, the market price of the Company's common
stock has been and may continue to be subject to significant fluctuations as a
result of factors affecting the Company, the software industry or the securities
markets in general.

  In addition, a large percentage of the Company's common stock is held by TA
Associates, Inc. and various institutional investors. Consequently, actions with
respect to the Company's common stock by either TA Associates, Inc. or certain
of these institutional investors could have a significant impact on the market
price for the stock.

RAPIDLY CHANGING TECHNOLOGY; NEW PRODUCTS; RISK OF PRODUCT DEFECTS. The markets
for the Company's products are generally characterized by rapidly changing
technology and frequent new product introductions that can render existing
products obsolete or unmarketable. A major factor in the Company's future
success will be its ability to anticipate technological changes and to develop
and introduce in a timely manner enhancements to its existing products and new
products to meet those changes. If the Company is unable to introduce new
products and respond quickly to industry changes, its business, financial
condition and results of operations could be materially adversely affected. The
introduction and marketing of new or enhanced products require the Company to
manage the transition from existing products in order to minimize disruption in
customer purchasing patterns. There can be no assurance that the Company will be
successful in developing and marketing, on a timely basis, new products or
product enhancements, that its new products will adequately address the changing
needs of the marketplace or that it will successfully manage the transition from
existing products. Software products as complex as those offered by the Company
may contain undetected errors or failures when first introduced or as new
versions are released, and the likelihood of errors is increased as a result of
the Company's commitment to accelerating the frequency of its product releases.
There can be no assurance that errors will not be found in new or enhanced
products after commencement of commercial shipments. Any of these problems may
result in the loss of or delay in market acceptance, diversion of development
resources, damage to the Company's reputation or increased service or warranty
costs, any of which could have a materially adverse effect on the Company's
business, financial condition and results of operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


DEPENDENCE ON DISTRIBUTORS. The Company distributes its products principally
through its global network of 35 independent, regional ASDs. The ASDs sell ANSYS
and DesignSpace products to new and existing customers, expand installations
within their existing customer base, offer consulting services and provide the
first line of ANSYS technical support. The ASDs have more immediate contact with
most customers who use ANSYS software than does the Company. Consequently, the
Company is highly dependent on the efforts of the ASDs. Difficulties in ongoing
relationships with ASDs, such as delays in collecting accounts receivable,
failure to meet performance criteria or to promote the Company's products as
aggressively as the Company expects and differences in the handling of customer
relationships could adversely affect the Company's performance. Additionally,
the loss of any major ASD for any reason, including an ASD's decision to sell
competing products rather than the Company's products, could have a materially
adverse effect on the Company. Moreover, the Company's future success will
depend substantially on the ability and willingness of its ASDs to continue to
dedicate the resources necessary to promote the Company's products and to
support a larger installed base of the Company's products. If the ASDs are
unable or unwilling to do so, the Company may be unable to sustain revenue
growth.

COMPETITION. The CAD, CAE and computer-aided manufacturing ("CAM") markets are
intensely competitive. In the traditional CAE market, the Company's primary
competitors include MacNeal-Schwendler Corporation, Hibbitt, Karlsson and
Sorenson, Inc. and MARC Analysis Research Corporation. The Company also faces
competition from smaller vendors of specialized analysis applications in fields
such as computational fluid dynamics. In addition, certain integrated CAD
suppliers such as Parametric Technology Corporation, Structural Dynamics
Research Corporation and Dassault Systemes provide varying levels of design
analysis and optimization and verification capabilities as part of their product
offerings. The entrance of new competitors would likely intensify competition in
all or a portion of the overall CAD, CAE and CAM markets. Some of the Company's
current and possible future competitors have greater financial, technical,
marketing and other resources than the Company, and some have well established
relationships with current and potential customers of the Company. It is also
possible that alliances among competitors may emerge and rapidly acquire
significant market share or that competition will increase as a result of
software industry consolidation. Increased competition may result in price
reductions, reduced profitability and loss of market share, any of which would
materially adversely affect the Company's business, financial condition and
results of operations.

DEPENDENCE ON SENIOR MANAGEMENT AND KEY TECHNICAL PERSONNEL. The Company is
highly dependent upon the ability and experience of its senior executives and
its key technical and other management employees. Although the Company has
entered into employment agreements with two executives, the loss of these, or
any of the Company's other key employees, could adversely affect the Company's
ability to conduct its operations.

RISKS ASSOCIATED WITH INTERNATIONAL ACTIVITIES. A significant and growing
portion of the Company's business comes from outside the United States. Risks
inherent in the Company's international business activities include imposition
of government controls, export license requirements, restrictions on the export
of critical technology, political and economic instability, trade restrictions,
changes in tariffs and taxes, difficulties in staffing and managing
international operations, longer accounts receivable payment cycles and the
burdens of complying with a wide variety of foreign laws and regulations.
Effective patent, copyright and trade secret protection may not be available in
every foreign country in which the Company sells its products. The Company's
business, financial condition and results of operations could be materially
adversely affected by any of these risks.

  Additionally, countries in the Asia-Pacific region, including Japan, have
continued to experience weaknesses in their currency, banking and equity
markets. These weaknesses could adversely affect consumer demand for the
Company's products and ultimately the Company's financial position or results of
operations.

DEPENDENCE ON PROPRIETARY TECHNOLOGY. The Company's success is highly dependent
upon its proprietary technology. The Company does not have patents on any of its
technology and relies on contracts and the laws of copyright and trade secrets
to protect its technology. Although the Company maintains a trade secrets
program, enters into confidentiality agreements with its employees and
distributors and limits access to and distribution of its software,
documentation and other proprietary information, there can be no assurance that
the steps taken by the Company to protect its proprietary technology will be
adequate to prevent misappropriation of its technology by third parties, or that
third parties will not be able to develop similar technology independently.
Although the Company is not aware that any of its technology infringes upon the
rights of third parties, there can be no assurance that other parties will not
assert technology infringement claims against the Company, or that, if asserted,
such claims will not prevail.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


INCREASED RELIANCE ON NONCANCELLABLE ANNUAL LEASES AND PERPETUAL LICENSES. The
Company has historically maintained stable recurring revenue from the sale of
monthly lease licenses for its software products. During certain periods in the
past, the Company experienced an increase in customer preference for perpetual
licenses that involve payment of a single up-front fee and that are more typical
in the computer software industry. Most recently it has experienced an increase
in customer preference for noncancellable annual leases. While monthly lease
license revenue currently represents a portion of the Company's software license
fee revenue, to the extent that noncancellable annual lease license and
perpetual license revenue continue to increase as a percentage of total software
license fee revenue, the Company's revenue in any period will increasingly
depend on sales completed during that period.

RISKS ASSOCIATED WITH ACQUISITIONS. The Company has consummated and may continue
to consummate certain strategic acquisitions in order to provide increased
capabilities to its existing products, enter new product and service markets or
enhance its distribution channels. The ability of the Company to integrate the
acquired businesses, including delivering sales and support, ensuring continued
customer commitment, obtaining further commitments and challenges associated
with expanding sales in particular markets and retaining key personnel, will
impact the success of these acquisitions. If the Company is unable to properly
and timely integrate the acquired businesses, there could be a materially
adverse effect on the Company's business, financial condition and results of
operations.

GENERAL CONTINGENCIES. The Company is subject to various investigations, claims
and legal proceedings from time to time that arise in the ordinary course of its
business activities. These proceedings include a current Internal Revenue
Service examination of the Federal income tax return for the fiscal year ended
December 31, 1996. Each of these matters is subject to various uncertainties,
and it is possible that some of these matters may be resolved unfavorably to the
Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 
1. ORGANIZATION AND INITIAL PUBLIC OFFERING

  ANSYS, Inc. (the "Company"), formerly SAS Holdings, Inc., is a holding company
incorporated on January 12, 1994 for the purpose of acquiring substantially all
of the assets and technology, and assuming certain liabilities of Swanson
Analysis Systems, Inc. (the "1994 Acquisition"). The Company develops, markets
and supports a family of mechanical computer-aided engineering software
products. The Company's products are marketed and sold to companies throughout
the world which operate in many industries, including automotive, aerospace and
electronics.

  Effective June 20, 1996, the Company completed an initial public offering
("IPO") of 3,500,000 shares of Common Stock at $13.00 per share. The net
proceeds (after deducting underwriting discounts and commissions and offering
expenses) totaled $41.0 million and were used as follows: (i) the repayment of
approximately $18.5 million of senior secured indebtedness (the "1994 Loan"),
including accrued and unpaid interest; (ii) the repayment of $17.5 million of
10% Subordinated Notes (the "Subordinated Notes"), including accrued and unpaid
interest; and (iii) the redemption of $5.1 million of Redeemable Preferred
Stock, including accumulated dividends.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION: The accompanying consolidated financial statements
include the accounts of the Company and its wholly-owned subsidiaries, ASN
Systems Limited, SAS IP, Inc. and ANSYS Foreign Sales Corporation. All
significant intercompany accounts and transactions have been eliminated in
consolidation.

REVENUE RECOGNITION: In October 1997, the Financial Accounting Standards Board
approved the American Institute of Certified Public Accountants Statement of
Position ("SOP") 97-2, "Software Revenue Recognition." This SOP provides
guidance on when revenue should be recognized and in what amounts for licensing,
selling, leasing or otherwise marketing computer software. This SOP supersedes
SOP 91-1, "Software Revenue Recognition." Beginning in December 1997, the
Company has adopted the provisions of SOP 97-2 and its current revenue
recognition policies are in conformance with the guidelines of the Statement.

  The Company's products are sold primarily through distributors, who are
resellers with respect to the Company's products. Revenue is derived principally
from the licensing of computer software products, either on an annual lease,
monthly lease or perpetual basis, and from related maintenance contracts.
Revenue from product licensing for perpetual licenses is recognized upon
delivery of the product, acceptance by the customer and receipt of a signed
contractual obligation provided that no significant Company obligations remain
and collection of the receivable is probable. A portion of the license fees from
noncancellable annual leases is recognized as paid-up revenue upon inception of
the lease. The remaining portion is recognized ratably over the remaining lease
period. Revenue for monthly lease licenses is recognized monthly, as earned,
because the lease license agreements can be cancelled by the customers with 30
days notice. Revenue from maintenance contracts is recognized ratably over the
term of the contract. Costs related to maintenance obligations are expensed as
incurred. Revenue from training, support and other services is recognized as the
services are performed.

CASH EQUIVALENTS: For purposes of the consolidated statements of cash flows, the
Company considers highly liquid deposits in money market funds to be cash
equivalents. Cash equivalents are recorded at cost, which approximates fair
value.

SHORT-TERM INVESTMENTS: The Company considers investments backed by government
agencies or U.S. financial institutions and which have a maturity or renewal
option between thirty days and up to one year from the date of purchase to be
short-term investments. Short-term investments are recorded at cost, which
approximates fair value.

SECURITIES AVAILABLE FOR SALE: The Company follows the provisions of Statement
of Financial Accounting Standards No. 115, "Accounting for Certain Investments
in Debt and Equity Securities," which addresses the classification, accounting
and disclosure of investments in debt and equity securities. In accordance with
Statement No. 115, the Company has investments in marketable equity securities
that have been classified as available-for-sale, and accordingly are carried at
fair value, with the unrealized gains and losses, net of tax, reported in a
separate component of stockholders' equity.

PROPERTY AND EQUIPMENT: Property and equipment is stated at cost. Depreciation
is computed on the straight-line method over the estimated useful lives of the
various classes of assets, which range from one to seven years. Repairs and
maintenance are charged to expense as incurred. Gains or losses from the sale or
retirement of property and equipment are included in the results of operations.

CAPITALIZED SOFTWARE: Internally developed computer software costs and costs of
product enhancements are capitalized subsequent to the determination of
technological feasibility; such capitalization continues until the product
becomes available for general release. Amortization of capitalized software
costs, both for internally developed as well as for purchased software products,
is computed on a product-by-product basis

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


over the estimated economic life of the product, which is generally three years.
Amortization is the greater of the amount computed using: (i) the ratio of the
current year's gross revenue to the total current and anticipated future gross
revenue for that product or (ii) the straight-line method over the estimated
life of the product.

  The Company periodically reviews the carrying value of capitalized software,
and impairments are recognized in the results of operations when the expected
future undiscounted operating cash flow derived from the capitalized software is
less than its carrying value.

RESEARCH AND DEVELOPMENT COSTS: Research and development costs are expensed as
incurred.

GOODWILL AND OTHER INTANGIBLE ASSETS: Intangible assets consist of the excess of
the purchase cost over the fair value of net assets acquired ("goodwill"), the
ANSYS trade name and non-compete agreements. These assets are being amortized on
the straight-line method over their estimated useful lives. The Company
periodically evaluates the carrying value of goodwill based on whether the
goodwill is recoverable from expected future undiscounted operating cash flows
of the related business. The Company periodically reviews the carrying value of
other intangible assets and will recognize impairments when the expected future
operating cash flow derived from such intangible assets is less than their
carrying value.

DEBT ISSUANCE COSTS: Debt issuance costs, which were incurred by the Company in
connection with the 1994 Acquisition, were deferred and amortized over the term
of the related debt. Debt issuance costs had been included in other intangibles
on the consolidated balance sheets. As a result of the early repayment of the
1994 Loan with a portion of the net proceeds from the IPO, the Company wrote off
the unamortized balance of the debt issuance cost, which was reflected as an
extraordinary item, net of income taxes, in the Consolidated Statement of Income
for the year ended December 31, 1996.

CONCENTRATIONS OF CREDIT RISK: The Company invests its excess cash primarily in
deposits, money market funds and commercial paper with commercial banks. The
Company has not experienced any losses to date on its invested cash.

  The Company has a concentration of credit risk with respect to trade
receivables because of the limited number of distributors through which the
Company sells its products. The Company performs periodic credit evaluations of
its customers' financial condition and generally does not require collateral.

  During 1998, sales by distributors comprised approximately 82% of the
Company's total revenue, with two distributors accounting for approximately 13%
and 10% of total revenue. During 1997, sales by distributors comprised
approximately 97% of the Company's total revenue, with two distributors
accounting for approximately 14% and 10% of total revenue. During 1996, sales by
distributors comprised approximately 96% of the Company's total revenue, with
two distributors accounting for approximately 13% and 9% of total revenue.

INCOME TAXES: Deferred tax assets and liabilities are determined based on
temporary differences between the financial statement and tax bases of assets
and liabilities, using enacted tax rates in effect in the years in which the
differences are expected to reverse. Valuation allowances are established when
necessary to reduce deferred tax assets to the amount expected to be realized.

FOREIGN CURRENCY TRANSACTIONS: Certain of the Company's sales transactions are
denominated in foreign currencies. These transactions are translated to U.S.
dollars at the exchange rate on the transaction date. Accounts receivable in
foreign currencies at year-end are translated at the effective exchange rate on
that date. Gains and losses resulting from foreign exchange transactions are
included in the results of operations.

USE OF ESTIMATES: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements. Estimates also affect the amounts of revenue and expenses during the
reported periods. Actual results could differ from the estimates.

EARNINGS PER SHARE: Effective December 31, 1997, the Company has adopted
Statement of Financial Accounting Standards No. 128, "Earnings per Share,"
issued in February 1997. This Statement requires the disclosure of basic and
diluted earnings per share and revises the method to calculate these amounts
under previous standards. Earnings per share data for periods prior to 1997 have
been restated to reflect adoption of this Statement. The adoption of this
standard did not materially impact previously reported earnings per share
amounts. Net income per basic common share is computed using the weighted
average number of common shares outstanding during each period. Net income per
diluted common share is computed using the weighted average number of common and
common equivalent shares outstanding during each period. Common equivalent
shares are not included in the per share calculations where their inclusion
would be anti-dilutive.

RECLASSIFICATIONS: Certain reclassifications have been made to the 1997 and 1996
financial statements to conform to the 1998 presentation.

  Based upon the Company's current and historical taxable income and the
anticipated level of future taxable income, management believes it is more
likely than not that all of the deferred tax assets will be realized.
Accordingly, no valuation allowance has been established against the deferred
tax assets.

7. STOCKHOLDERS' EQUITY

  The Company is authorized to issue up to 50,000,000 shares of $.01 par value
voting common stock. Upon the closing of the Company's IPO, each Class A share
was converted into one share of common stock. Subsequently, the Class A common
stock was cancelled.

  On April 19, 1996, the Board of Directors authorized 2,000,000 shares of
undesignated preferred stock issuable in one or more series by the Board of
Directors. At December 31, 1998 and 1997, there were no shares of preferred
stock issued or outstanding.

8. PENSION AND PROFIT-SHARING PLANS

  The Company maintains both a money purchase pension plan (the "Pension Plan")
and a 401(k) / profit-sharing plan (the "Profit-Sharing Plan") for all
qualifying full-time employees. The Pension Plan is a noncontributory plan and
required the Company to contribute 20% of each participant's compensation
annually in 1997 and 1996. A plan amendment, effective January 1, 1998, reduced
the Company contribution to 5% of each participant's salary.

  In 1997 and 1996, the Profit-Sharing Plan was noncontributory. An amendment to
this plan, effective January 1, 1998, invoked the 401(k) feature of the plan,
thereby permitting employee contributions up to 10% of eligible compensation.
The Company makes matching contributions on behalf of each participant in an
amount equal to 100% of the employee contribution up to a maximum of 5% of
employee compensation. The employee vesting period was also amended to a five
year graduated vesting schedule for employer contributions. Under the profit-
sharing provisions of the plan, the Company contribution is determined annually
by the Board of Directors, subject to a maximum limitation of 5% of eligible
compensation.

  Total expense related to the Pension and Profit-Sharing plans was $1,144,000
in 1998, $2,566,000 in 1997 and $1,882,000 in 1996.

9. NON-COMPETE AND EMPLOYMENT AGREEMENTS

  The Company has entered into non-compete agreements with certain holders of
the Company's common stock. The agreements preclude the stockholders from
competing either directly or indirectly with the Company for a period ranging
from one to three years subsequent to termination. Additionally, during 1997,
the Company exercised an option for a non-compete agreement related to
activities in the Company's United Kingdom and Netherlands territories. The
agreement precludes the former ASD from engaging in any competitive business
activities previously undertaken pursuant to the former ASD agreement.

  The Company has entered into employment agreements with the Chief Executive
Officer and another senior executive. The terms of the agreements are
substantially similar except with respect to minimum annual base salary. In the
event the Chief Executive Officer is terminated without cause, his employment
agreement provides for severance at the annual rate of $300,000 for the later of
a period of one year after termination or when he accepts other employment. In
the event the other senior executive is terminated without cause, his employment
agreement provides that the Company will continue to pay his base salary of
$256,000, subject to specified cost of living increases, through the later of
March 14, 1999 or six months from the date of termination. The Chief Executive
Officer and the other senior executive are subject to one and three-year
restrictions on competition, respectively, following termination of employment
under the circumstances described in each contract.

10. STOCK OPTION AND GRANT PLANS

  The Company has two stock option and grant plans -- the 1994 Stock Option and
Grant Plan ("1994 Stock Plan") and the 1996 Stock Option and Grant Plan ("1996
Stock Plan"). The 1994 and 1996 Stock Plans authorize the grant of up to 868,110
and 3,250,000 shares, respectively, of the Company's common stock in the form
of: (i) incentive stock options ("ISOs"), (ii) nonqualified stock options or
(iii) the issuance or sale of common stock with or without vesting or other
restrictions. Additionally, the 1996 Stock Plan permits the grant of common
stock upon the attainment of specified performance goals and the grant of the
right to receive cash dividends with the holders of the common stock as if the
recipient held a specified number of shares of the common stock. No further
grants may be made under the 1994 Stock Plan.

  The 1994 and 1996 Stock Plans provide that: (i) the exercise price of an ISO
must be no less than the fair value of the stock at the date of grant and (ii)
the exercise price of an ISO held by an optionee who possesses more than 10% of
the total combined voting power of all classes of stock must be no less than
110% of the fair market value of the stock at the time of grant. The Board of
Directors has the authority to set expiration dates no later than ten years from
the date of grant (or five years for an optionee who meets the 10% criteria),
payment terms and other provisions for each grant. Shares associated with
unexercised options or repurchased shares of common stock become available for
options or issuances under the 1996 Stock Plan. The Compensation Committee of
the Board of Directors may, at its sole discretion, accelerate or extend the
date or dates on which all or any particular award or awards granted under the
1994 and 1996 Stock Plans may vest or be exercised. In the event of a merger,
liquidation or sale of substantially all of the assets of the Company, the Board
of Directors has the discretion to accelerate the vesting of the options granted
under the 1994 and 1996 Stock Plans, except that options granted to the Chief
Executive Officer and Independent Directors vest automatically. Under certain
scenarios, other optionees may also automatically vest upon the occurrence of
such an event. In addition, the 1994 and 1996 Stock Plans and the grants issued
thereunder terminate upon the effectiveness of any such transaction or event,
unless a provision is made in connection with such transaction for the
assumption of grants theretofore made. Under the 1996 Stock Plan, at the
discretion of the Compensation Committee, any option may include a "reload"
feature. Such feature allows an optionee exercising an option to receive, in
addition to the number of shares of common stock due on the exercise, an
additional option with an exercise price equal to the fair market value of the
common stock on the date such additional option is granted.

  In addition, the 1996 Stock Plan provides for the automatic grant of
nonqualified options to Independent Directors. Under such provisions, options to
purchase that number of shares of common stock determined by dividing $200,000
by the option exercise price will be granted to each individual when he or she
first becomes a member of the Board of Directors, provided that he or she is not
an employee of the Company. In addition, in 1998 the Board of Directors amended
the 1996 Stock Plan to provide that on the date five business days following
each annual meeting of stockholders of the Company, each Independent Director
who is then serving will be granted an option to purchase 12,000 shares of
common stock at the option exercise price. Options granted to Independent
Directors under the foregoing provisions will vest in annual installments over
four years, commencing with the date of grant and will expire ten years after
the grant, subject to earlier termination if the optionee ceases to serve as a
director. The exercisability of these options will be accelerated upon the
occurrence of a merger, liquidation or sale of substantially all of the assets
of the Company.

  During 1994, the Company issued 1,289,750 shares of restricted common stock to
certain officers, employees and members of the Board of Directors. In addition,
during 1996 the Company issued 135,860 shares of restricted common stock to an
officer and during 1995 issued 30,000 shares of restricted common stock to
members of the Board of Directors. Substantially all shares of restricted stock
and all of the options under both the 1994 and 1996 Stock Plans were issued at
the estimated market value of the Company's common stock at the time of
issuance. The recipients of the restricted stock are required to continue in the
employment or service of the Company for periods of up to five years after the
date of issuance for ownership to vest and provide for repurchase of unvested
restricted stock by the Company at the original purchase price in the event of
the termination of employment prior to vesting. Upon termination of employment,
the Company repurchased 14,950, 3,950 and 16,750 shares of restricted stock from
employees in 1998, 1997 and 1996, respectively.

  The Company has elected to account for stock-based compensation arrangements
under the provisions of Accounting Principles Board Opinion No. 25, "Accounting
for Stock-Based Compensation." The Company has adopted the disclosure-only
provisions of Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation." Accordingly, no compensation expense has been
recognized for restricted stock or options which have been issued under the 1994
and 1996 Stock Plans. Had compensation cost for the Company's two stock option
and grant plans been determined based upon the fair value at the grant date for
the option awards in 1998, 1997 and 1996 consistent with the provisions of SFAS
No. 123, the Company's net income and basic and diluted earnings per share would
have been reduced to the pro forma amounts indicated on the following page:

  The weighted-average fair value of options granted was $8.83 per share in
1998, $6.65 per share in 1997 and $9.03 per share in 1996.

  The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the risk-free interest rates ranging
from a low of 4.25% to a high of 5.63%. The interest rates used were determined
by using the five year Treasury Note rate at the date of grant. The following
assumptions were also used to determine the fair value of each option grant:
dividend yields of 0%; expected volatility of 66% and expected term of five
years.

11. EMPLOYEE STOCK PURCHASE PLAN

  The Company's 1996 Employee Stock Purchase Plan (the "Purchase Plan") was
adopted by the Board of Directors on April 19, 1996 and was subsequently
approved by the Company's stockholders. Up to 210,000 shares of common stock may
be issued under the Purchase Plan. The Purchase Plan is administered by the
Compensation Committee. The first offering under the Purchase Plan commenced on
August 1, 1996 and closed on January 31, 1997. Subsequent offerings commence on
each February 1 and August 1 thereafter, and have a duration of six months. An
employee who owns or is deemed to own shares of stock representing in excess of
5% of the combined voting power of all classes of stock of the Company may not
participate in the Purchase Plan.

  During each offering, an eligible employee may purchase shares under the
Purchase Plan by authorizing payroll deductions of up to 10% of his cash
compensation during the offering period. The maximum number of shares which may
be purchased by any participating employee during any offering period is limited
to 960 shares (as adjusted by the Compensation Committee from time to time).
Unless the employee has previously withdrawn from the offering, his accumulated
payroll deductions will be used to purchase common stock on the last business
day of the period at a price equal to 85% of the fair market value of the common
stock on the first or last day of the offering period, whichever is lower. Under
applicable tax rules, an employee may purchase no more than $25,000 worth of
common stock in any calendar year. At December 31, 1998, 61,926 shares of common
stock had been issued under the Purchase Plan of which 37,877 were issued as of
December 31, 1997.

12. LEASES

  In January 1996 the Company entered into a lease agreement with an unrelated
third party for a new corporate office facility, which the Company occupied in
February 1997. The lease agreement is for ten years, with an option for five
additional years, and includes a rental acceleration at the end of the fifth and
tenth years. The Company incurred lease rental expense related to this facility
of $1,227,000 and $1,022,000 in 1998 and 1997, respectively. Future minimum
lease payments under the facility lease are $1,227,000 per annum through 2001.

  Prior to February 1997, the Company had operated from facilities which it had
leased from a joint venture held by a corporate officer. The Company incurred
lease rental expense related to this lease agreement of $138,000 for the year
ended December 31, 1997 and $839,000 for the year ended December 31, 1996.

  The Company has also entered into various noncancellable operating leases for
equipment and sales offices. Lease rental expense related to these leases
totaled $1,136,000, $1,125,000 and $1,211,000 for the years ended December 31,
1998, 1997 and 1996, respectively. Future minimum lease payments under
noncancellable operating leases for equipment and sales offices in effect at
December 31, 1998 are $616,000 in 1999, $189,000 in 2000 and $79,000 in 2001.

13. ROYALTY AGREEMENTS

  The Company has entered into various renewable nonexclusive license agreements
under which the Company has been granted access to the licensor's patent
technology and the right to sell the patent technology in the Company's product
line. Royalties are payable to developers of the software at various rates and
amounts generally based upon unit sales or revenue. Royalty fees, which are
included in cost of sales, were approximately $489,000, $422,000 and $450,000
for the years ended December 31, 1998, 1997 and 1996, respectively.

14. RELATED PARTY TRANSACTIONS

  In connection with his initial employment, the Company's Chief Executive
Officer purchased 626,000 restricted shares of common stock in July 1994 for a
cash purchase price of $250,000 with proceeds from a loan from the Company
evidenced by a promissory note bearing interest at 8.23% and maturing on July 8,
2006. The promissory note is collateralized by a pledge of the shares purchased
with the proceeds of the loan. The shares purchased by the Chief Executive
Officer became fully vested during 1998.

16. COMMITMENTS AND CONTINGENCIES

  The Company had an outstanding irrevocable standby letter of credit for
$1,577,000 at December 31, 1998. This letter of credit, which expires on April
8, 1999, was issued as a guarantee for court-awarded damages related to
litigation initiated by the Company. The fair value of the letter of credit
approximates the contract value based on the nature of the fee arrangements with
the issuing bank. No material losses on this commitment have been incurred, nor
are any anticipated.

  The Company is subject to various investigations, claims and legal proceedings
from time to time that arise in the ordinary course of its business activities.
These proceedings include a current Internal Revenue Service examination of the
Federal income tax return for the fiscal year ended December 31, 1996. Each of
these matters is subject to various uncertainties, and it is possible that some
of these matters may be resolved unfavorably to the Company. The Company has
established accruals for matters that are probable and reasonably estimable.
Management believes that any liability that may ultimately result from the
resolution of these matters in excess of the amounts provided will not have a
material adverse effect on the financial position or results of operations of
the Company.

17. EARNINGS PER SHARE

  Basic earnings per common share ("EPS") amounts are computed by dividing
earnings after the deduction of preferred stock dividends by the average number
of common shares outstanding. Diluted EPS amounts assume the issuance of common
stock for all potentially dilutive equivalents outstanding.

  The details of basic and diluted earnings per common share are as follows:

18. LITIGATION

  The Company is currently the plaintiff in litigation related to the expiration
of an ASD distribution agreement. However, the action has not progressed
sufficiently for the Company to estimate a range of possible gain, if any,
should it prevail in its pursuit of damages related to this action.

19. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

  In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities," which defines derivatives, requires that all
derivatives be carried at fair value and provides for hedge accounting when
certain conditions are met. The Standard is effective for all fiscal quarters of
fiscal years beginning after June 15, 1999. The Company is currently in the
process of evaluating the prospective impact of Statement No. 133 on its
financial position and results of operations.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
   Ansys Inc. and Subsidiaries:

We have audited the financial statements of the 1996 Employee Stock Purchase 
Plan of ANSYS, Inc. and Subsidiaries as of January 31, 1999 and 1998 and for the
years ended January 31, 1999 and 1998 and for the period August 1, 1996 through 
January 31, 1997, as listed in the accompanying index on Page 2. These financial
statements are the responsibility of the Plan's management. Our responsibility 
is to express an opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the statements of financial condition of the 1996 
Employee Stock Purchase Plan of ANSYS, Inc. and Subsidiaries as of January 31, 
1999 and 1998, and changes in Plan equity for the years ended January 31, 1999 
and 1998 and for the period August 1, 1996 through January 31, 1997, in 
conformity with generally accepted accounting principles.

                       1996 EMPLOYEE STOCK PURCHASE PLAN
                         NOTES TO FINANCIAL STATEMENTS

1.  DESCRIPTION OF PLAN:

The purpose of the 1996 Employee Stock Purchase Plan of Ansys, Inc. and
Subsidiaries (the "Plan"), which became effective August 1, 1996, is to provide
eligible employees of ANSYS, Inc. and certain of its subsidiaries (the
"Company") with opportunities to purchase shares of common stock upon favorable
terms. The aggregate maximum number of shares for which options may be issued
under the Plan is 210,000 shares of common stock, subject to adjustments for
changes in the Company's capitalization. The Plan is administered by the
Compensation Committee of the Board of Directors (the "Compensation Committee").

Participation in the Plan is voluntary. Offerings under the Plan commence on 
each February 1 and August 1 and have a duration of six months. The
Compensation Committee may establish a different period of six months or less
for any offering. Generally, all employees who are employed for more than 20
hours per week as of the first day of the applicable offering period are
eligible to participate in the Plan. An employee who owns or is deemed to own
shares of stock representing in excess of 5% of the combined voting power of all
classes of stock of the Company may not participate in the Plan.

During each offering, an eligible employee may purchase shares under the Plan by
authorizing payroll deductions of up to 10% per pay period, to be deducted from
such employee's total cash compensation. The maximum number of shares which may
be purchased by any participating employee during any offering period is limited
to 960 shares (as adjusted by the Compensation Committee from time to time).
Unless the employee has previously withdrawn from the offering, such employee's
accumulated payroll deductions will be used to purchase common stock at a price
equal to 85% of the fair market value of the common stock on the first or last
day of the offering period, whichever is lower. The Company will contribute the
remaining 15% of the fair market value of the common stock. Under applicable tax
rules, an employee may purchase no more than $25,000 worth of common stock in
any calendar year.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued):

Administrative Expenses:

The Company pays all expenses incident to the operation of the Plan, including 
the costs of record keeping, accounting fees, legal fees, the costs of delivery 
of stock certificates to participants and the costs of shareholder 
communications.  The Company does not pay any expenses, broker's or other 
commissions or taxes incurred in connection with the purchases of Common Stock, 
or the sale of shares of Common Stock.

Use of Estimates:

The preparation of financial statements in conformity with generally accepted
accounting principles requires the plan administrator to make estimates and
assumptions that affect certain reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements. Estimates may also affect the changes in Plan equity during the
reporting period. Actual results may differ from those estimates.

Reclassifications:

Certain prior year balances have been reclassified to conform with the current 
year presentation. The financial statements have been classified to reflect the 
obligation for stock distributions due to participants as of the plan year end
as a liability.
