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 support
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 2001, the Company enhanced its ISO 9001 quality system and achieved ISO
9001:2000 certification. This standard applies to the ANSYS, DesignSpace and
AI*Solutions software suite products, and covers all product-related activities,
from establishing product requirements to customer service practices and
procedures.

In accordance with the ISO 9001:2000 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 and supports its products through its global ASD and
reseller network, as well as through its own strategic direct sales offices.
This network provides the Company with a cost-effective, highly specialized
channel of distribution and technical support. Approximately 57% of the
Company's total revenue in 2001 was derived through the ASD and reseller
network.

At December 31, 2001, the ASD network consisted of 30 independent distributors
in 37 countries, including 13 in North America, 6 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 expanding product lines and provide an acceptable level of training,
consultation and customer support.

                                       4
===============================================================================


The Company also has a direct sales management infrastructure in place to
develop an enterprise-wide, focused sales approach and to implement a worldwide
major account strategy. The sales management organization also functions as a
focal point for requests to ANSYS from the ASD and reseller channel, and
provides additional support in strategic locations through the presence of
direct sales offices. As of December 31, 2001, a Vice President of Sales and
Support, with a supporting North American Vice President of Sales, a European
Vice President of Sales, and an International Vice President of Sales, headed
the Company's sales management organization. These senior members of sales
management were supported by Regional Sales Directors, devoted to the overall
management of stated sales territories, and Strategic Account Managers, devoted
to specific major accounts within those territories.

During 2001, the Company continued to invest in its existing domestic and
international strategic sales offices and established a new sales office in
India during the latter part of 2001. In total, the Company's direct sales
offices employ 96 persons, who are responsible for the sales, marketing
initiatives and administrative activities in those geographic areas designed to
support the Company's overall revenue growth and market share expansion
strategies.

During 2001, the Company also continued to expand the reseller channel for both
its ANSYS and DesignSpace products. This channel complements the ASD network by
establishing a broader user base for the Company's products and services. As of
December 31, 2001, the Company had signed agreements with over 200 resellers.
The resellers are required to have appropriately trained marketing and technical
personnel.

The Company's products have an installed base of approximately 74,000 seats at
commercial sites and approximately 126,000 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 10% of the Company's revenue in 2001.

Information with respect to foreign and domestic revenue may be found in Note 14
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, 2001 ("2001 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.

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, CAD and PLM providers. The Company believes
these relationships allow accelerated incorporation of advanced technology into
the ANSYS, DesignSpace, AI*Solutions, ICEM CFD and CADOE product families,
provide access to important new markets, expand the Company's sales channels,
develop specialized product applications and provide direct integration with
leading CAD systems.

The Company has technical and marketing relationships with leading CAD vendors,
such as Autodesk, Parametric Technology Corporation, Dassault Systemes and
Electronic Data Systems to provide direct links between products. These links
facilitate the transfer of electronic data models between the CAD system and
ANSYS products.

In 2001, the Company announced a strategic OEM partnership with SAS LLC, a
provider of NASTRAN simulation software and services. This global alliance will
be focused on the joint development of a new NASTRAN computer-aided engineering
solution that will be distributed exclusively by the Company. The solution will
integrate the technologies of ANSYS, Inc., CADOE S.A., ICEM CFD Engineering and
SAS LLC to provide users with a comprehensive NASTRAN product.

The Company has established relationships with leading suppliers of computer
hardware, including Hewlett-Packard, Compaq, SGI, Sun Microsystems, IBM, Dell,
Intel and various graphics card vendors. These relationships typically provide
the Company with joint marketing opportunities such as advertising, events and
internet links with the hardware partner's home page. In addition, the Company
receives reduced equipment costs and software porting support to ensure that the
Company's software products are certified to run on various hardware platforms.

The Company's Enhanced Solution Partner Program actively encourages specialized
developers of niche software solutions to use ANSYS as a development platform
for their applications. In most cases, the sale of the Enhanced Solution
Partners' products is accompanied by the sale of an ANSYS product.

                                       5
===============================================================================


The Company has a software license agreement with Livermore Software Technology
Corporation ("LSTC") under which LSTC 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, LSTC assists in the
integration of the LS-DYNA software with the Company's pre- and post-processing
capabilities and provides updates and problem resolution in return for a share
of revenue from sales of ANSYS/LS-DYNA.

The Company has a software license agreement with International Technology
Group, Inc. (ITI) under which ITI provides CADfix software and associated tools
and utilities aimed at improving the success of transferring geometry from
multiple CAD programs to ANSYS software products. Under this agreement, ITI
assists in the integration of CADfix software with the Company's products and
provides updates and problem resolution in return for a share of revenue from
sales of CADfix for ANSYS.

The Company also partners with SimUtility, Inc. to provide the e-CAE ASP program
via e-CAE.com. This program provides a mechanism for running large ANSYS
simulations on parallel compute servers at a remote data center site using the
Internet or dedicated lines. The system has been developed to allow users the
ability to submit jobs in a "batch" style of computing, with specific controls
on job execution parameters, and is ideal for users who require occasional
"surge" capacity for time critical simulations or periodic simulations of large
models.

COMPETITION

The CAD, CAE and computer-aided manufacturing ("CAM") markets are intensely
competitive. In the traditional CAE market, the Company's primary competitors
include MSC.Software Corporation and Hibbitt, Karlsson and Sorensen, Inc. The
Company also faces competition from smaller vendors of specialized analysis
applications in fields such as computational fluid dynamics. In addition,
certain integrated CAD and PLM suppliers such as Parametric Technology
Corporation, Electronic Data Systems Corporation and Dassault Systemes provide
varying levels of design analysis, 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; breadth and depth of functionality; 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.

                                       6
===============================================================================


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 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 through the ASDs and the reseller channel,
license agreements for the Company's products are directly between the Company
and end users. Use of the licensed software is restricted to designated
computers at specified sites, unless the customer obtains a site license for its
use of the software. Software 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 annually purchase ongoing maintenance, technical support and
updates, or may lease the product on an annual basis for a fee which includes
the license, maintenance, technical support and upgrades.

For certain software products, such as ANSYS/ED, the Company primarily relies on
"click-wrapped" licenses. 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 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. Additionally, the Company was awarded a patent by the U.S. Patent and
Trademark Office for its web-based reporting technology.

The employees of the Company have signed covenant agreements 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 are the property of the Company.
In addition, the Company requires all ASDs and resellers 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 does not believe 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.

                                       7
===============================================================================


EMPLOYEES

As of December 31, 2001, the Company had approximately 450 full-time employees.
At that date, there were also approximately 30 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 feet
office facility in Canonsburg, Pennsylvania, which was leased for an annual rent
of approximately $1,227,000 in 2001. This annual rent will increase to
approximately $1,354,000 in 2002. The Company also leases office space in
various locations throughout the world. The Company's subsidiaries lease office
space for their operations as well. 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 its business activities. These proceedings currently
include customary audit activities by various taxing authorities. 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
quarter of fiscal year 2001.
