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; 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 and Stock Price 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. Such factors include, but are not limited
            to, declines in trading price that may be triggered
            by the Company's failure to meet the expectations of
            securities analysts and investors. The Company
            cannot provide assurance that in such circumstances
            the trading price of the Company's common stock will
            recover or that it will not experience a further
            decline.  Moreover, the trading price could be
            subject to additional fluctuations in response to
            quarter-to-quarter variations in the Company's
            operating results, material announcements made by
            the Company or its competitors, conditions in the
            software industry generally, or other events and
            factors, many of which are beyond the Company's
            control.

            In addition, a large percentage of the Company's
            common stock is held by investment funds
            associated with 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 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 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 MSC.Software
            Corporation and Hibbitt, Karlsson and Sorenson, 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 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 Personnel.
            The Company is highly dependent upon the
            ability and experience of its senior executives and
            its key technical, sales and other management employees.
            Although the Company has entered into an employment
            agreement with one executive, the loss of this
            employee, 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 certain international
            regions 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 Perpetual Leases. The Company
            has historically maintained stable recurring revenue
            from the sale of monthly lease licenses and
            noncancellable annual leases for its software
            products.  More 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.  While revenue generated
            from monthly lease licenses and noncancellable
            annual leases currently represents a portion of the
            Company's software license revenue, to the extent
            that perpetual license revenue continues to increase
            as a percentage of total software license 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 certain state income tax and sales and use
            tax examinations.  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.

            Year 2000 Computer Systems Compliance. 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 its 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 the Year 2000."
             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.
