EXHIBIT 99 Certain Factors Regarding Future Results
               
            Information provided by the Company or its
            spokespersons 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; 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. 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 revenues 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 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 Company and software
            industry or 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 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 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 33 independent, regional ANSYS
            Support Distributors ("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, 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, 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, computer-aided engineering
            ("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 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 likely
            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.
            
            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.
            
            
            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
            percent of total software license fee revenue, the
            Company's revenue in any period will increasingly
            depend on sales completed during that period.
            
            
            Management's Assessment of Year 2000 Readiness. The
            Company has developed a plan to address the possible
            exposures related to the impact of the Year 2000 on
            its products, as well as it internal computer
            software and hardware systems.  Details of the
            Company's Year 2000 Plan, along with further
            information regarding costs, timing and risks are
            contained in the "Management's Discussion and
            Analysis of Financial Condition and Results of
            Operations" section of this Form 10-Q under the
            heading "Management's Assessment of Year 2000
            Readiness." The timely resolution of Year 2000
            issues by the Company and its distributors,
            customers and suppliers is based upon certain
            assumptions and estimates of the Company and
            independent third parties. To the extent these prove
            to be incorrect or inaccurate, or the Company or its
            distributors, customers or suppliers experience
            unanticipated delays or expenses, this could cause
            the actual outcome to differ materially from the
            projected results.
