EXHIBIT 99  Certain Factors Regarding Future Results

                Information provided by the Company or its spokespersons from
              time to time may 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; 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; 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
              personnel expenses cannot be adjusted quickly and is based, in
              significant part, on the Company's expectation for future
              revenues. 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. As a result, product revenues in any quarter
              are substantially dependent on orders booked and shipped in the
              latter part of that quarter, and revenues for any future quarter
              are 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 computer industry or the securities markets
              in general.

                In addition, a large percentage of the Company's common stock is
              held by institutional investors. Consequently, actions with
              respect to the Company's common stock by 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 to
              industry changes on a timely basis, 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

                                                                               1

 
              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 upon the Company's
              business, financial condition and results of operations.
 
                Dependence on Distributors. The Company distributes its products
              principally through its global network of 35 independent, regional
              ANSYS Support Distributors ("ASDs"). The ASDs sell ANSYS products
              and other noncompeting 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, ASDs' 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 ANSYS
              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") market is 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 and Structural Dynamics Research
              Corporation provide varying levels of design analysis and
              optimization and verification capabilities as part of their
              product offerings.
 
                The entrance of new competitors would be likely to intensify
              competition in all or a portion of the overall CAD, CAE and CAM
              market. 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.

                                                                               2

 
                Dependence on Senior Management and Key Technical Personnel. The
              Company is highly dependent upon the ability and experience of its
              senior executives, Peter J. Smith and Dr. John A. Swanson, and its
              key technical and other management employees. Although the Company
              has entered into employment agreements with Mr. Smith and Dr.
              Swanson, the loss of either of these senior executives or a number
              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 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.

                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.

                Increased Reliance on Perpetual Licenses. The Company has
              historically maintained stable recurring revenue from the sale of
              time-based licenses for its software products. Recently, the
              Company has 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.
              Although lease license revenue currently represents a majority of
              the Company's software license fee revenue, to the extent that
              perpetual license revenue increases as a percent of total software
              license fee revenue, the Company's revenue in any period will
              increasingly depend on sales completed during that period.

                                                                               3
