THE MERGER (SEE PAGE 20)

     The proposed merger involves the following:

     - Ansoft Acquisition Corp., a wholly owned subsidiary of Ansoft, will merge
       with and into Pacific Numerix and Ansoft Acquisition Corp's independent
       corporate existence will cease

     - the common and preferred stock of Pacific Numerix outstanding immediately
       prior to the merger will be converted into the right to receive a total
       of 121,030 shares of Ansoft common stock and cash of approximately
       $7,000.00.

     - the Pacific Numerix common and preferred stock currently held by Ansoft
       will be retired

     - after the merger, the former stockholders of Pacific Numerix receiving
       shares of Ansoft Common Stock in the merger will own approximately 1% of
       Ansoft common stock issued and outstanding immediately after the merger.

                                        1
<PAGE>   9

     We expect to complete the merger by December 31, 1999. However, we cannot
predict the exact timing of the merger because it is subject to a number of
conditions.

     If you have any questions about the merger or the annual meeting, please
call Anthony Ryan, Chief Financial Officer and Secretary, Ansoft Corporation, at
(412) 261-3200.

PACIFIC NUMERIX'S REASONS FOR THE MERGER (SEE PAGE 20)

     The board of directors of Pacific Numerix believes that the merger provides
Pacific Numerix with the opportunity to combine with Ansoft on terms that are
fair from a financial point of view to Pacific Numerix and its stockholders
(other than Ansoft). The board believes that the merger will, among other
things, provide Pacific Numerix stockholders with the liquidity of a publicly
traded stock.

THE MERGER AGREEMENT (SEE PAGE 25)

     We attached, as Annex A, the merger agreement between Pacific Numerix,
Ansoft, and a wholly owned subsidiary of Ansoft. We encourage you to read this
document. Ansoft has also filed with the Securities and Exchange Commission
other related documents as exhibits to its registration statement. Please see
the section titled "Where You Can Find More Information," on page 107, for
instructions on how to obtain copies of those exhibits.

CONDITIONS TO CONSUMMATION OF THE MERGER (SEE PAGE 27)

     The parties will complete the merger only if a number of conditions are
satisfied or waived, including the following:

     - approval of the merger agreement by the stockholders of Pacific Numerix,
       a condition which will be satisfied because Ansoft owns a majority of the
       voting power of Pacific Numerix and has indicated that it will approve
       the merger agreement.

     - as a condition for Ansoft, the exercise of appraisal rights by holders of
       not more than 5.0% of Pacific Numerix common and preferred stock in the
       aggregate.

     - the SEC having declared effective Ansoft's registration statement
       covering the Ansoft common stock to be issued in the merger.

     - as a condition for Pacific Numerix, listing for quotation on the Nasdaq
       National Market of the shares of Ansoft common stock to be issued in the
       merger.

TERMINATION (SEE PAGE 28)

     Either Ansoft or Pacific Numerix may terminate the merger agreement if:

     - for any reason the merger shall not have been consummated within 120 days
       after the date of the merger agreement and the failure to consummate the
       merger is not caused by a breach of the merger agreement by the
       terminating party

     - any court of competent jurisdiction or other competent governmental or
       regulatory authority shall have issued a nonappealable order restricting,
       preventing or otherwise prohibiting the merger

     Ansoft and Pacific Numerix also may mutually agree to terminate the merger
agreement prior to completion of the merger.

AMENDMENT OR EXTENSION (SEE PAGE 28)

     Consistent with Delaware and Nevada law, the merger agreement provides that
Pacific Numerix and Ansoft may, by mutual agreement, amend, modify, supplement,
extend or abandon the agreement at any time prior to the effective time of the
merger, even following stockholder approval. The merger agreement permits the
boards of directors of Pacific Numerix and Ansoft to amend the merger agreement
after stockholder approval if the amendment does not (1) alter or change the
amount or kind of merger consideration

                                        2
<PAGE>   10

received, (2) alter or change any term of the articles of incorporation of
Pacific Numerix, or (3) alter or change any of the terms and conditions of the
agreement in a way that would adversely affect the holders of any class or
series of securities held by such stockholders.

ACCOUNTING TREATMENT (SEE PAGE 23)

     Ansoft will account for this transaction as a purchase.

POST-MERGER BOARD OF DIRECTORS (SEE PAGE 25)

     The merger agreement provides that, upon completion of the merger, the
directors of Pacific Numerix shall be:

     Zoltan Cendes,
     Nicholas Csendes

     Pacific Numerix's board of directors will also have four vacancies.

FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 22)

     Each Pacific Numerix stockholder will recognize a gain or loss with respect
to each share of Pacific Numerix common stock surrendered equal to the
difference between the stockholder's basis in such share and the fair market
value, as of the effective time of the merger, of the Ansoft common stock and
cash received in exchange therefor.

APPRAISAL RIGHTS (SEE PAGE 23)

     Under Nevada law holders of Pacific Numerix common and preferred stock have
the right to demand payment of fair value for their shares, in cash, as
determined by a court, in lieu of the Ansoft common stock they are entitled to
receive in the merger.

     It is a condition to the merger that the holders of not more than 5% of
Pacific Numerix common and preferred stock exercise appraisal rights. Ansoft may
waive this right. Pacific Numerix stockholders who desire to exercise their
appraisal rights must carefully follow the procedures described in this proxy
statement/prospectus.

STOCK LISTING

     Ansoft will continue to list its common stock on the Nasdaq National Market
after the merger.

INTERESTS OF CERTAIN PERSONS IN THE MERGER (SEE PAGE 35)

     Certain relationships among the directors, officers and stockholders of
Ansoft and Pacific Numerix give rise to conflicts of interest between the
parties in the negotiation of the terms and conditions of the merger. Those
relationships include the following:

     - Mr. Zoltan Cendes, the Chairman of the board of directors and Chief
       Technology Officer of Ansoft, serves as a director of Pacific Numerix

     - Mr. Nicholas Csendes, a director and the President and Chief Executive
       Officer of Ansoft, serves as the Chairman, President and a director of
       Pacific Numerix

     - Mr. Ryan, the Chief Financial Officer and Secretary of Ansoft serves as
       Secretary of Pacific Numerix

     - Ansoft beneficially owns 75% of the outstanding shares of Pacific Numerix
       common stock and 74% of the outstanding shares of preferred stock.

     The merger agreement between Pacific Numerix, Ansoft and Ansoft Acquisition
Corp., a wholly-owned subsidiary of Ansoft, and the merger provided for therein
was negotiated on behalf of Pacific Numerix by officers of Pacific Numerix who
also serve as officers of Ansoft based on pricing negotiated with respect to
Ansoft's prior purchases of common and preferred stock of Pacific Numerix from
unaffiliated stockholders of Pacific Numerix.

SHARES ELIGIBLE FOR FUTURE SALE (SEE PAGE 24)

     Pacific Numerix stockholders who were not Ansoft affiliates at the time the
merger agreement is submitted for approval by Pacific Numerix stockholders may
resell the Ansoft common stock acquired by them in the merger free of these
restrictions.

     To our knowledge, no Pacific Numerix stockholder who will be receiving
Ansoft common stock in the merger is an affiliate of Ansoft. These stockholders
are expected to own approximately 1% of Ansoft common stock after the merger.

UNAUDITED COMPARATIVE PER COMMON SHARE DATA

     The following table sets forth certain historical per share data of Ansoft
and Pacific Numerix and combined per share data on an unaudited pro forma basis
after giving effect to the business combination on a purchase basis of
accounting, assuming that .09236 shares of Ansoft common stock are issued in
exchange for one share of Pacific Numerix common stock and .15655 shares of
Ansoft common stock are issued in exchange for one share of Pacific Numerix
preferred stock in the business combination. This data should be read in
conjunction with the selected historical financial data, the unaudited pro forma
combined condensed financial data, and the separate historical financial
statements of Ansoft and Pacific Numerix and notes (which are included elsewhere
in this document). The pro forma combined condensed financial data are not
necessarily indicative of the operating results that would have been achieved
had the business combination been consummated as of the beginning of the periods
presented and should not be construed as representative of results for any
future period.

(1) Ansoft's most recent fiscal year end is April 30, 1999. Pacific Numerix's
    most recent fiscal year end is December 31, 1998.

(2) The most recent period end is the three-months ended July 31, 1999 for both
    Ansoft and Pacific Numerix.

(3) The unaudited equivalent pro forma per share amounts are calculated by
    multiplying Ansoft pro forma per share amounts by the assumed weighted
    average exchange ratio of .09430 for each outstanding share of Pacific
    Numerix stock. This ratio is used for disclosure purposes in this document.
    The actual average exchange ratio for each holder of PNC stock will depend
    on the holder's mix of common and preferred stock as the exchange ratio is

                                  RISK FACTORS

     BEFORE YOU INVEST IN ANSOFT'S COMMON STOCK, YOU SHOULD BE AWARE THAT THERE
ARE VARIOUS RISKS, INCLUDING THOSE DESCRIBED BELOW. YOU SHOULD CONSIDER
CAREFULLY THESE RISK FACTORS TOGETHER WITH ALL OF THE OTHER INFORMATION INCLUDED
IN THIS PROSPECTUS BEFORE YOU DECIDE TO PURCHASE SHARES OF ANSOFT'S COMMON
STOCK.

WE MAY BE UNABLE TO
SUCCESSFULLY COMPETE IN THE
HIGHLY COMPETITIVE
ELECTRONIC
DESIGN AUTOMATION ("EDA")
SOFTWARE MARKET                The electronic design automation software market
                               in which Ansoft competes is intensely competitive
                               and subject to rapid change. In general,
                               competition comes from major EDA vendors, many of
                               which have a longer operating history,
                               significantly greater financial, technical and
                               marketing resources, greater name recognition and
                               a larger installed customer base than Ansoft.
                               These companies also have established
                               relationships with current and potential
                               customers of Ansoft. Ansoft's software products
                               currently compete with certain software offerings
                               from Hewlett-Packard Corporation ("HP"). Ansoft
                               also competes directly with certain major EDA
                               vendors and privately-held companies which also
                               provide competing products. Ansoft also competes,
                               on a limited basis, with the internal development
                               groups of its existing and potential customers,
                               many of which design and develop customized
                               design tools for their particular needs. In
                               addition, the EDA industry has become
                               increasingly concentrated in recent years as a
                               result of acquisitions, and further concentration
                               within the EDA industry could result in increased
                               competition for Ansoft. Increased competition
                               could result in price reductions, reduced margins
                               or loss of market share, any of which could
                               seriously harm Ansoft's business, operating
                               results or financial condition. Ansoft may be
                               unable to compete successfully against current
                               and future competitors, and competitive pressures
                               faced by Ansoft could seriously harm Ansoft's
                               business, operating results and financial
                               condition.

WE HAVE A HISTORY OF LOSSES
AND OUR FUTURE OPERATING
RESULTS ARE UNCERTAIN          Ansoft has incurred net losses in each fiscal
                               year since its founding with the exception of
                               fiscal 1998 and 1996. There can be no assurance
                               that Ansoft's revenue and net income will grow or
                               be sustained in future periods or that Ansoft
                               will remain profitable in any future period.
                               Future operating results will depend on many
                               factors, including the degree and the rate of
                               growth of the markets in which Ansoft competes
                               and the accompanying demand for Ansoft's
                               products, the level of product and price
                               competition, the ability of Ansoft to develop and
                               market new products and to control costs, the
                               ability of Ansoft to expand its direct sales
                               force and the ability of Ansoft to attract and
                               retain key personnel.

OUR QUARTERLY OPERATING
RESULTS ARE DIFFICULT TO
PREDICT                        We are unable to accurately forecast our future
                               revenues primarily because of the emerging nature
                               of the market in

                                       10
<PAGE>   18

                               which we compete. Our revenues and operating
                               results generally depend on the size, timing and
                               structure of significant licenses. These factors
                               have historically been, and are likely to
                               continue to be, difficult to forecast. In
                               addition, our current and future expense levels
                               are based largely on our operating plans and
                               estimates of future revenues and are, to a
                               extent, fixed. We may be unable to adjust
                               spending sufficiently quickly to compensate for
                               any unexpected revenue shortfall. Accordingly,
                               any significant shortfall in revenues in relation
                               to our planned expenditures would seriously harm
                               our business, financial condition and results of
                               operations. Such shortfalls in our revenue or
                               operating results from levels expected by public
                               market analysts and investors could seriously
                               harm the trading price of our common stock.
                               Additionally, we may not learn of such revenue
                               shortfalls, earnings shortfalls or other failure
                               to meet market expectations until late in a
                               fiscal quarter, which could result in an even
                               more immediate and serious harm to the trading
                               price of our common stock. Our quarterly
                               operating results have varied, and it is
                               anticipated that our quarterly operating results
                               will vary, substantially from period to period
                               depending on various factors, many of which are
                               outside our control. Due to the foregoing
                               factors, we cannot predict with any significant
                               degree of certainty our quarterly revenue and
                               operating results. Further, we believe that
                               period-to-period comparisons of our operating
                               results are not necessarily a meaningful
                               indication of future performance.

OUR STOCK PRICE IS
EXTREMELY
VOLATILE                       The trading price of our common stock has
                               fluctuated significantly in the past, and the
                               trading price of our common stock is likely to be
                               highly volatile and could be subject to wide
                               fluctuations in price in response to such factors
                               as:

                                    -- Actual or anticipated fluctuations in our
                                       operating results;

                                    -- Announcements of technological
                                       innovations and new products by us or our
                                       competitors;

                                    -- New contractual relationships with
                                       strategic partners by us or our
                                       competitors;

                                    -- Proposed acquisitions by us or our
                                       competitors; and

                                    -- Financial results that fail to meet
                                       public market analyst expectations of
                                       performance.

                               In addition, the stock market in general, and The
                               Nasdaq National Market and the market for
                               technology companies in particular has
                               experienced extreme price and volume

                                       11
<PAGE>   19

                               fluctuations that have often been unrelated or
                               disproportionate to the operating performance of
                               such companies. These broad market and industry
                               factors may seriously harm the market price of
                               our common stock in future periods.

BUSINESSES WE ACQUIRE MAY
NOT PERFORM AS PROJECTED       We have acquired or merged with a number of
                               companies in recent years, including the
                               acquisitions of: a majority interest in Pacific
                               Numerix, Compact Software, Inc., the Electronic
                               Business Unit of MacNeal Schwendler Company and
                               Boulder Microwave Technologies, and as part of
                               our efforts to increase revenue and expand our
                               product and services offerings we may acquire
                               additional companies. In addition to direct
                               costs, acquisitions pose a number of risks,
                               including potential dilution of earnings per
                               share, delays and other problems of integrating
                               the acquired products and employees into our
                               business, the failure to realize expected
                               synergies or cost savings, the failure of
                               acquired products to achieve projected sales, the
                               drain on management time for acquisition-related
                               activities, possible adverse effects on customer
                               buying patterns due to uncertainties resulting
                               from an acquisition, and assumption of unknown
                               liabilities. The foregoing factors could
                               seriously harm our business, financial condition
                               and results of operations.

RISKS ASSOCIATED WITH
COMPANY INVESTMENTS            Ansoft invested a portion of the proceeds of its
                               initial public offering in certain long-, medium-
                               and short-term investment grade, interest-bearing
                               securities. The value of Ansoft's investment in
                               such instruments is subject to the normal risks
                               of interest-bearing investments. Over time, the
                               level of interest rates available in the market
                               changes. As prevailing rates fall, the prices of
                               bonds and other securities that trade on a yield
                               basis tend to rise. Conversely, when prevailing
                               interest rates rise, bond prices generally will
                               fall. Generally, the longer the maturity of a
                               fixed-income security, the higher its yield and
                               the greater its price volatility. As a
                               consequence, the value of the bonds and other
                               instruments held by Ansoft could fluctuate
                               substantially over time, depending upon long-term
                               and short-term trends and interest rates.

WE MAY LOSE COMPETITIVE
ADVANTAGES IF OUR
PROPRIETARY
RIGHTS ARE INADEQUATELY
PROTECTED                      Ansoft's success depends, in part, upon its
                               proprietary technology. We rely on a combination
                               of patents, trade secrets, copyrights, trademarks
                               and contractual commitments to protect our
                               proprietary rights in our software products. We
                               generally enter into confidentiality or license
                               agreements with our employees, distributors and
                               customers, and limit access to and distribution
                               of our software, documentation and other
                               proprietary information. Despite these
                               precautions, a third party may still copy or

                                       12

                               otherwise obtain and use our products or
                               technology without authorization, or develop
                               similar technology independently. In addition,
                               effective patent, copyright and trade secret
                               protection may be unavailable or limited in
                               certain foreign countries. It is possible that we
                               may fail to adequately protect our proprietary
                               rights. This would seriously harm Ansoft's
                               business, operating results and financial
                               condition.

WE MAY BE UNABLE TO ATTRACT
AND RETAIN THE KEY
MANAGEMENT AND TECHNICAL
PERSONNEL THAT WE NEED TO
SUCCEED                        Ansoft's future operating results depend in large
                               part upon the continued services of its key
                               technical and management personnel, including Dr.
                               Zoltan J. Cendes, a founder, Chairman of the
                               Board of Directors and Chief Technology Officer
                               of Ansoft. Ansoft does not have employment
                               contracts with Dr. Cendes or any other executive
                               officer. Ansoft maintains key-man life insurance
                               with respect to Dr. Cendes in the amount of
                               $5,000,000. Ansoft's future success will also
                               depend in large part on its ability to continue
                               to attract and retain highly skilled technical,
                               marketing and management personnel. The
                               competition for such personnel, as well as for
                               qualified EDA engineers, is intense. If Ansoft is
                               unable to attract, hire and retain qualified
                               personnel in the future, the development of new
                               products and the management of Ansoft's
                               increasingly complex business would be impaired.
                               This could seriously harm Ansoft's business,
                               operating results and financial condition.

WE HAD PREVIOUSLY DEPENDED
UPON THIRD-PARTY
INTERNATIONAL DISTRIBUTORS
AND
HAVE RECENTLY SHIFTED OUR
DISTRIBUTION MODEL TO THE
USE
OF DIRECT SALES PERSONNEL
IN
INTERNATIONAL MARKETS          A significant portion of Ansoft's license and
                               service revenue results from a limited number of
                               international distributors. During fiscal 1999,
                               1998 and 1997, revenue from international
                               distributors accounted for approximately 10%,
                               19%, and 19%, respectively, of Ansoft's total
                               revenue. Ansoft's distributors are not obligated
                               to purchase products from Ansoft and may also
                               represent other products. Ansoft has recently
                               shifted its distribution model to the use of
                               direct sales personnel in international markets.
                               It is possible that we may fail to sustain or
                               increase revenue previously derived from
                               third-party international distributors and,
                               consequently, seriously harm our business,
                               financial condition and results of operations.

WE DEPEND ON INTERNATIONAL
SALES FOR A SIGNIFICANT
PERCENTAGE OF OUR REVENUE      International revenue, principally from Asian
                               customers, accounted for approximately 52% and
                               51% of our total revenue in the three-month
                               period ended July 31, 1999 and 1998,
                               respectively. We expect that international
                               license and service revenue will continue to
                               account for a significant portion of our total
                               revenue for the foreseeable

                               future. Our international business activities are
                               subject to a variety of potential risks,
                               including:

                                    -- The impact of recessionary environments
                                       in foreign economies;

                                    -- Longer receivables collection periods and
                                       greater difficulty in accounts receivable
                                       collection;

                                    -- Difficulties in staffing and managing
                                       foreign operations;

                                    -- Political and economic instability;

                                    -- Unexpected changes in regulatory
                                       requirements;

                                    -- Reduced protection of intellectual
                                       property rights in some countries; and

                                    -- Tariffs and other trade barriers.

                               Currency exchange fluctuations in countries in
                               which we license our products could also
                               seriously harm our business, financial condition
                               and results of operations by resulting in pricing
                               that is not competitive with products priced in
                               local currencies. Furthermore, we may not be able
                               to continue to generally price our products and
                               services internationally in U.S. dollars because
                               of changing sovereign restrictions on importation
                               and exportation of foreign currencies as well as
                               other practical considerations. In addition, the
                               laws of certain countries do not protect our
                               products and intellectual property rights to the
                               same extent, as do the laws of the United States.
                               Moreover, it is possible that we may fail to
                               sustain or increase revenue derived from
                               international licensing and service or that the
                               foregoing factors will seriously harm our future
                               international license and service revenue, and,
                               consequently, seriously harm our business,
                               financial condition and results of operations.

WE NEED TO SUCCESSFULLY
MANAGE OUR EXPANDING
OPERATIONS                     Ansoft has experienced rapid growth in recent
                               years which has placed and could continue to
                               place a significant strain on the its managerial
                               and other resources. Revenues have grown from
                               $6.2 million in fiscal 1995 to $24.4 million in
                               fiscal year 1999, and the number of employees has
                               grown from 69 in April 1996 to 234 as of July 31,
                               1999. Ansoft's ability to manage growth
                               effectively will require it to continue to
                               improve its operational and financial systems,
                               hire and train new employees and add additional
                               space, both domestically and internationally.
                               Ansoft may not be successful in addressing such
                               risks, and the failure to do so would seriously
                               harm Ansoft's business, financial condition and
                               results of operations.

WE DEPEND ON THE GROWTH OF
THE COMMUNICATIONS,
SEMICONDUCTOR AND
ELECTRONICS
INDUSTRIES                     Ansoft is dependent upon the communications and
semiconductor industry and, more generally, the electronics industry. These
                               industries are characterized by rapid
                               technological change, short product life cycles,
                               fluctuations in manufacturing capacity and
                               pricing and gross margin pressures. Segments of
                               these industries have from time to time
                               experienced significant economic downturns
                               characterized by decreased product demand,
                               production over-capacity, price erosion, work
                               slowdowns and layoffs. While these industries
                               have experienced an extended period of
                               significant economic growth over the past few
                               years, such economic growth may not continue, and
                               if it does not, any downturn could be especially
                               severe on Ansoft. During such downturns, the
                               number of new integrated circuit design projects
                               often decreases. Because acquisitions of new
                               licenses from Ansoft are largely dependent upon
                               the commencement of new design projects, any
                               slowdown in these industries could seriously harm
                               Ansoft's business, financial condition and
                               results of operations.

ERRORS IN OUR SOFTWARE
PRODUCTS COULD RESULT IN
LOSS
OF MARKET SHARE OR FAILURE
TO
ACHIEVE MARKET ACCEPTANCE      Software products as complex as those offered by
                               Ansoft may contain defects or failures when
                               introduced or when new versions are released.
                               Ansoft has in the past discovered software
                               defects in certain of its products and may
                               experience delays or lost revenue to correct such
                               defects in the future. Despite testing by Ansoft,
                               errors may still be found in new products or
                               releases after commencement of commercial
                               shipments, resulting in loss of market share or
                               failure to achieve market acceptance. Any such
                               occurrence could seriously harm Ansoft's
                               business, financial condition and results of
                               operations.

WE ARE CONTROLLED BY OUR
PRINCIPAL STOCKHOLDERS AND
MANAGEMENT WHICH MAY LIMIT
YOUR ABILITY TO INFLUENCE
STOCKHOLDER MATTERS            Our executive officers, directors and principal
                               stockholders own approximately 49% of the
                               outstanding shares of Ansoft common stock. As a
                               result, they have the ability to effectively
                               control us and direct our affairs, including the
                               election of directors and approval of significant
                               corporate transactions. This concentration of
                               ownership also may have the effect of delaying,
                               deferring or preventing a change in control of
                               our company and may make some transactions more
                               difficult or impossible without the support of
                               these stockholders. The interests of these
                               stockholders may conflict with those of other
                               stockholders.

ANTI-TAKEOVER PROVISIONS IN
ANSOFT'S CERTIFICATE OF
INCORPORATION, BYLAWS, AND
UNDER DELAWARE LAW COULD
PREVENT AN ACQUISITION OF
ANSOFT                         We have adopted a number of provisions that could
                               have anti-takeover effects. The Board of
                               Directors has the authority to issue up to
                               1,000,000 shares of Preferred Stock without any
                               further vote or action by Ansoft's stockholders.

                               of Incorporation, Bylaws and Delaware Law may
                               have the effect of deterring hostile takeovers or
                               delaying or

directions specified on the proxies. If no directions are indicated on a
properly executed proxy, such proxy will be voted for approval of the merger
agreement.

     If any other matters are properly presented at the special meeting for
consideration, the persons named in the enclosed forms of proxy will have
discretion to vote on such matters in accordance with their best judgment.
However, proxies voting against a specific proposal may not be used by the

       or preferred stock and delivering it as indicated below before the vote
       is taken at the special meeting

     - attending the special meeting and voting in person

     Attendance at the special meeting will not in and of itself constitute a
revocation of a proxy. Any written notice of revocation or subsequent proxy must

vote is taken at the special meeting.

     WHO IS PAYING FOR THE SOLICITATION?  Pacific Numerix will bear all expenses
of the solicitation of proxies for the special meeting. In addition to
solicitation by use of the mails, proxies may be solicited from stockholders by
Pacific Numerix directors, officers and employees. Solicitation may take place
in person or by telephone, facsimile or other means of communication. Such
directors, officers and employees will not be additionally compensated, but may
be reimbursed for reasonable out-of-pocket expenses in connection with such
solicitation.

     HOW ARE ABSTENTIONS TREATED?  Abstentions will be tabulated separately and
will be counted as present at the meeting for purposes of determining whether a
quorum is present at the special meeting. Because the agreement requires the
approval of the holders of at least a majority of the voting power of the
outstanding shares of Pacific Numerix common and preferred stock, abstentions
will have the effect of votes against approval of the agreement.

                                  PROPOSAL 1:

                                   THE MERGER

     At the special meeting, you will be asked to approve the merger agreement,
in which a wholly-owned subsidiary of Ansoft will merge with and into Pacific
Numerix. As a result of the merger, Pacific Numerix will become a wholly-owned
subsidiary of Ansoft. Pacific Numerix's and Ansoft's board of directors have
each unanimously approved the merger agreement. The merger agreement is attached
as Annex A to this proxy statement/ prospectus.

BACKGROUND OF THE MERGER

     Following extensive negotiations between Ansoft and certain major
stockholders of Pacific Numerix, on April 28, 1999, Ansoft purchased from
certain then current stockholders of Pacific Numerix 3,789,014 shares of Pacific
Numerix common stock and 116,500 shares of Pacific Numerix preferred stock. The
purchase price per share of such purchase was 0.09236 shares of Ansoft common
stock for each share of Pacific Numerix common stock, and .15655 shares of
Ansoft common stock for each share of Pacific Numerix preferred stock, for a
total of 372,442 shares of Ansoft common stock, the same conversion ratio that
is being offered by Ansoft pursuant to this proxy statement/ prospectus. The
Ansoft common stock was issued pursuant to exemptions from the registration
requirements of the 1933 Securities Act, pursuant to Section 4(2) of Regulation
D promulgated thereunder concerning transactions not involving a public
offering. Officers of Ansoft thereafter assumed the management and operation of
Pacific Numerix, paid off its outstanding debt, and began to integrate Pacific
Numerix's product marketing and development within Ansoft's established product
marketing and development structure.

     On September 9, 1999, the board of directors of Pacific Numerix (by this
time consisting of Nicholas Csendes and Zoltan Cendes, both officers of Ansoft)
concluded that the merger is in the best interests of Pacific Numerix and its
stockholders (other than Ansoft). The board considered all of the information
and factors described below, which constituted all of the material information
and factors known to the board at that time, in deciding to approve the merger.
In reaching this conclusion, the board based its recommendation upon the
totality of the information and factors presented to it or otherwise known to
its members.

     FOR THE REASONS SET FORTH ABOVE AND ELSEWHERE IN THIS PROXY
STATEMENT/PROSPECTUS, THE PACIFIC NUMERIX BOARD OF DIRECTORS RECOMMENDS THAT
STOCKHOLDERS VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

PACIFIC NUMERIX REASONS FOR THE MERGER

     Pacific Numerix's board has determined that the terms of the merger and the
merger agreement are fair to, and in the best interests of, Pacific Numerix and
its stockholders. Accordingly, Pacific Numerix's board has approved the merger
agreement and the consummation of the merger and recommends that you vote for
approval of the merger agreement and the merger.

     Pacific Numerix's board consulted with its senior management, legal
counsel, independent accountants and financial advisers in reaching its decision
to approve the

                                       20
<PAGE>   28

merger. Among the factors considered by Pacific Numerix's board in its
deliberations were the following:

     - historical information concerning Ansoft's financial performance, results
       of operations, assets, liabilities, operations, technology, management
       and competitive position. This information included public reports of
       Ansoft covering the most recent fiscal year and fiscal quarter;

     - management's view of the financial condition, results of operations,
       assets, liabilities, businesses and prospects of Ansoft and Pacific
       Numerix after giving effect to the merger;

     - current market conditions and historical trading information with respect
       to Ansoft common stock; the terms and conditions of the merger agreement
       taken as a whole;

     - Ansoft's track record, which clearly demonstrates an ability to compete
       effectively in the electronic design automation market.

     In addition, the board based its decision, in part, on a presentation of
its senior management. The board believed that combining Pacific Numerix and
Ansoft would result in the following potential operating synergies and cost
savings:

     - elimination of duplicate expenses in sales and marketing, business
       development, administration, and product development; and

     - increased buying power due to the size of the combined entity.

     The board also identified and considered a variety of potential negative
factors in its deliberations concerning the merger, including, but not limited
to:

     - the risk to Pacific Numerix's stockholders that the value to be received
       in the merger could decline significantly due to the fixed exchange
       ratio;

     - the loss of control over the future operations of Pacific Numerix
       following the merger;

     - the risk that the potential benefits sought in the merger might not be
       fully realized;

     - the possibility that the merger might not be consummated and the
       potential adverse effects of the announcement of the merger on:

        - Pacific Numerix's sales and operating results;

        - Pacific Numerix's ability to attract and retain key employees;

        - the progress of certain strategic initiatives; and

     - the risk that key technical, sales and management personnel might resign
       following the closing of the merger.

     The board also considered the purchase price of the Pacific Numerix stock
in the April 28, 1999 transaction, and concluded that if would be fair to the
remaining stockholders of Pacific Numerix to receive substantially the same
consideration.

                                       21
<PAGE>   29

     After due consideration, the board concluded that the potential benefits of
the proposed merger outweighed the possible risks and after fully discussing
these matters the board determined that Ansoft's offer was justified and
proceeded to approve the merger.

     The foregoing discussion of the information and factors considered by the
board is not intended to be exhaustive but is believed to include all material
factors considered by the board. In view of the complexity and wide variety of
information and factors, both positive and negative, considered by the board, it
did not find it practical to quantify, rank or otherwise assign relative or
specific weights to the factors considered. The board also did not reach any
specific conclusion with respect to each of the factors considered, or any
aspect of any particular factor. Instead, the board conducted an overall
analysis of the factors described above, including thorough discussions with its
management and legal and accounting advisors. In considering the factors
described above, individual members of the board may have weighed factors
differently. The board considered all these factors as a whole and believe the
factors support its determination to approve the merger. Accordingly, the board
believes the merger is fair to, and in the best interests of, Pacific Numerix
and its stockholders and that Pacific Numerix should proceed with the merger.

     During the time period in which Pacific Numerix was engaged in discussions
with Ansoft, it did not receive any unsolicited offers regarding a possible
business combination with any third parties.

FEDERAL INCOME TAX CONSIDERATIONS

     The following is a discussion of the material federal income tax
considerations of the merger that are generally applicable to holders of Pacific
Numerix common stock.

     This discussion does not deal with all income tax considerations that may
be relevant to you. Some stockholders have particular circumstances such as
stockholders who are dealers in securities, foreign persons, banks, insurance
companies or tax-exempt entities; stockholders who acquired their shares in
connection with previous mergers involving Pacific Numerix or an affiliate;
stockholders who hold their shares as part of a hedging, straddle, conversion or
other risk reduction transaction; or stockholders who acquired their shares in
connection with stock option, stock purchase plans or other compensatory
transactions. In addition, the following discussion does not address the tax
consequences of transactions effectuated prior to or after the merger (whether
or not such transactions are in connection with the merger). Furthermore, no
foreign, state or local tax considerations are addressed in this proxy
statement/prospectus. The discussion is based on federal income tax law in
effect as of the date of this proxy statement/prospectus. These laws could
change at any time, possibly with retroactive effectiveness. Neither Pacific
Numerix nor Ansoft has requested or will request a ruling from the Internal
Revenue Service with regard to any of the tax consequences of the merger.

     Accordingly, Pacific Numerix stockholders are urged to consult their own
tax advisors as to the specific tax consequences of the merger. This includes
the applicable federal, state, local and foreign tax consequences to them of the
merger and applicable tax return reporting requirements.

     - Gain or loss will be recognized by holders of Pacific Numerix common and
       preferred stock solely upon their receipt of Ansoft common stock and cash
       in the merger;

                                       22
<PAGE>   30

     - Each Pacific Numerix stockholder will recognize a gain or loss with
       respect to each share of Pacific Numerix common or preferred stock
       surrendered equal to the difference between the stockholder's basis in
       such share and the sum of 1) the fair market value, as of the effective
       time of the merger, of the Ansoft common stock received in exchange
       therefor, and 2) the cash received.

ACCOUNTING TREATMENT

     The business combination will be accounted for under the purchase method of
accounting. Ansoft will record the assets and liabilities of Pacific Numerix at
their estimated fair value as of the closing date. The remaining intangible
assets of approximately $900,000 recorded with respect to the business
combination are expected to be amortized over a period of three to seven years
following the closing of the business combination.

APPRAISAL RIGHTS

NEVADA LAW

     Record holders of Pacific Numerix common and preferred stock that follow
the appropriate procedures are entitled to dissenters' rights under Sections
92A.300 through 92A.500 of the Nevada General Corporation Law (the "Nevada
Dissenters' Statute") in connection with the merger.

     The following discussion of the applicable provisions of the Nevada
Dissenters' Statute is not intended to be a complete statement of such
provisions and is qualified in its entirety by reference to the full text of the
Nevada Dissenters' Statute, which is reprinted in its entirety and attached as
Appendix B to this joint proxy statement/prospectus. A person having a
beneficial interest in shares of Pacific Numerix common or preferred stock that
are held of record in the name of another person, such as a bank, broker or
other nominee, must act promptly to cause the record holder to follow the steps
summarized below properly and in a timely manner if such person wishes to
perfect any dissenters' rights such person may have.

     This discussion and Appendix B should be reviewed carefully by any
stockholder of Pacific Numerix who wishes to exercise statutory dissenters'
rights or who wishes to preserve the right to do so, because failure to strictly
comply with any of the procedural requirements of the Nevada Dissenters' Statute
may result in a termination or waiver of dissenters' rights under the Nevada
Dissenters' Statute.

     Under the Nevada Dissenters' Statute, each Pacific Numerix stockholder has
the right to dissent from the merger and demand payment of the fair value of his
or her shares of Pacific Numerix common or preferred stock. If a stockholder
elects to dissent, the stockholder must file with Pacific Numerix a written
notice of dissent stating that such stockholder intends to demand payment for
his or her shares if the merger is consummated. Such written notice of dissent
must be filed with Pacific Numerix before the vote of Pacific Numerix
stockholders on the merger. If a stockholder fails to comply with this notice
requirement or votes in favor of the proposed transaction the stockholder will
not be entitled to appraisal rights. The "fair value" of the shares as used in
the Nevada Dissenters' Statute is determined as of the day prior to the Pacific
Numerix stockholder meeting being held to vote upon the merger.

                                       23
<PAGE>   31

     Within 10 days after the effective date of the merger, Ansoft will give
written notice of the effective date of the merger by certified mail to each
stockholder who filed a written notice of dissent, except for any stockholder
who voted for or consented in writing to the merger. The notice must also state
where demand for payment must be sent and where share certificates shall be
deposited, among other information. Within the time period set forth in the
notice, which may not be less than 30 days nor more than 60 days following the
date notice is delivered, the dissenting stockholder must make a written demand
on Ansoft for payment of the fair value of his or her shares and deposit his or
her share certificates in accordance with the notice.

     Within 30 days after the receipt of demand for the fair value of the
dissenter's shares, Ansoft will mail to each dissenting stockholder Pacific
Numerix's financial statements as of the end of the last fiscal year ending not
more than 16 months before the date of payment and the latest available interim
financial statements, if any. These financial statements will be accompanied by
payment in cash of fair value of such stockholder's shares as determined by
Ansoft, plus accrued interest.

     A dissenting stockholder, within 30 days following receipt of payment for
the shares, may send Ansoft a notice containing such stockholder's own estimate
of fair value and accrued interest, and demand payment for that amount less the
amount received pursuant to Ansoft's payment of fair value to such stockholder.

     If a demand for payment remains unsettled, Ansoft shall petition the court
to determine fair value and accrued interest. If Ansoft fails to commence an
action within 60 days following the receipt of the stockholder's estimate of
fair value, Ansoft shall pay to the stockholder the amount demanded by the
stockholder in the stockholder's notice containing the stockholder's estimate of
fair value and accrued interest.

     All dissenting stockholders, whether residents of Nevada or not, must be
made parties to the action and the court shall render judgment for the fair
value of their shares. Each party must be served with the petition. The judgment
shall include payment for the amount, if any, by which the court finds the fair
value of his shares, plus interest, exceeds the amount already paid. If the
court finds that the demand of any dissenting stockholder for payment was
arbitrary, vexatious or otherwise not in good faith, the court may assess costs,
including reasonable fees of counsel and experts, against such stockholder.
Otherwise the costs and expenses of bringing the appraisal action will be
determined by the court and will be apportioned and assessed as the court may
find equitable upon the parties or any of them. In addition, reasonable fees and
expenses of counsel and experts may be assessed against Ansoft if the court
finds that it did not substantially comply with the requirements of the Nevada
Dissenters' Statute or that it acted arbitrarily, vexatiously or not in good
faith.

DELAWARE LAW

     Delaware law provides appraisal rights to stockholders of Delaware
corporations in certain situations. Delaware law does not provide appraisal
rights to stockholders of a corporation, such as Ansoft, that issues shares in
connection with a merger but is not itself a constituent corporation in the
merger.

LISTING OF ANSOFT COMMON STOCK TO BE ISSUED IN THE MERGER

     It is a condition to the consummation of the merger that the shares of
Ansoft common stock to be issued in the merger be approved for listing on The
Nasdaq National Market. A description of Ansoft's common stock is provided on
page   .

RESTRICTION ON RESALES OF ANSOFT COMMON STOCK

     The Ansoft common stock to be issued in the merger will have been
registered under the Securities Act, thereby allowing such shares to be freely
traded without restriction by all former holders of Pacific Numerix common stock
who are not "affiliates" of Pacific Numerix at the time of the special meeting
and who do not become "affiliates" of Ansoft after the merger. Persons who may
be deemed to be affiliates of Ansoft or Pacific Numerix generally include
individuals or entities that control, are controlled by, or are under common
control with, such party and may include certain officers and directors of
Ansoft and Pacific Numerix, as well as significant stockholders.

     Shares of Ansoft common stock received by those stockholders of Pacific
Numerix who are deemed to be affiliates of Pacific Numerix may be resold without
registration under the Securities Act only as permitted by Rule 145 under the
Securities Act or as otherwise permitted under the Securities Act.

     This document does not cover resales of Ansoft common stock received by any
person who may be deemed to be an affiliate of Ansoft or Pacific Numerix.

THE MERGER AGREEMENT

     THE FOLLOWING IS A BRIEF SUMMARY OF THE MATERIAL PROVISIONS OF THE MERGER
AGREEMENT. A COPY OF THE MERGER AGREEMENT IS ATTACHED AS APPENDIX A TO THIS
DOCUMENT AND INCORPORATED HEREIN BY REFERENCE. YOU ARE URGED TO READ THE MERGER
AGREEMENT IN ITS ENTIRETY FOR A MORE COMPLETE DESCRIPTION OF THE MERGER. IN THE
EVENT OF ANY DISCREPANCY BETWEEN THE TERMS OF THE MERGER AGREEMENT AND THE
FOLLOWING SUMMARY, THE MERGER AGREEMENT WILL CONTROL.

THE MERGER

     Following the approval and adoption of the merger agreement by the
stockholders of Pacific Numerix and the satisfaction or waiver of the other
conditions to the merger, Pacific Numerix will merge with a wholly-owned
subsidiary of Ansoft. Pacific Numerix will continue as the surviving corporation
and a wholly-owned subsidiary of Ansoft.

THE EFFECTIVE TIME

     As soon as practicable on or after the closing of the merger, the parties
will cause the merger to become effective by filing a certificate of merger with
the Delaware Secretary of State and the Nevada Secretary of State. The parties
anticipate that this will occur             , 1999.

                                       25
<PAGE>   33

DIRECTORS AND OFFICERS OF PACIFIC NUMERIX AFTER THE MERGER

     At the effective time, the new directors of Pacific Numerix will be the
following: Zolton Cendes and Nicholas Csendes and the officers of Pacific
Numerix shall be: Nicholas Csendes, President, and Anthony Ryan, Secretary and
Treasurer.

CONVERSION OF SHARES IN THE MERGER

     At the effective time, each outstanding share of Pacific Numerix common
stock will be automatically canceled and converted into the right to receive
0.09236 shares of Ansoft common stock and each outstanding share of Pacific
Numerix preferred stock will be automatically canceled and converted into the
right to receive .15655 shares of Ansoft common stock, except that shares of
Pacific Numerix common and preferred stock held immediately prior to the
effective time by Pacific Numerix or Ansoft shall be canceled. However, if the
number of Ansoft shares that the holder is entitled to receive is not evenly
divisible by ten (10), the holder shall receive that number of Ansoft shares by
rounding down to the nearest number divisible by ten (10) and the remaining
number of shares, including any fractional share, that the holder has the right
to receive will be paid in cash at a value of $6.95 per Ansoft share. For
example, if a holder is entitled to receive 147 shares of Ansoft common stock,
such holder would receive 140 shares of Ansoft common stock and $48.65 in cash.
In addition, the exchange ratio will be further adjusted to reflect the effect
of any stock split, stock dividend, reorganization, recapitalization,
reclassification or other like change with respect to either Ansoft common stock
or Pacific Numerix common stock that may occur on or after the date of this
document but prior to the merger.

PACIFIC NUMERIX'S STOCK OPTION AND STOCK PURCHASE PLANS

     At the effective time, each outstanding option to purchase shares of
Pacific Numerix common stock under Pacific Numerix's Incentive Stock Option Plan
will be canceled by Ansoft regardless of whether they are exercisable.

PROCEDURES FOR EXCHANGING STOCK CERTIFICATES

     Promptly after the effective time, Ansoft will mail to the holders of
record of Pacific Numerix stock certificates, (1) a letter of transmittal and
(2) instructions on how to surrender Pacific Numerix stock certificates in
exchange for certificates representing shares of Ansoft common stock, cash for
fractional shares and any dividends or other distributions that they may be
entitled to receive under the merger agreement. HOLDERS OF PACIFIC NUMERIX STOCK
SHOULD NOT SURRENDER THEIR PACIFIC NUMERIX STOCK CERTIFICATES UNTIL THEY RECEIVE
THE LETTER OF TRANSMITTAL FROM ANSOFT.

     Upon surrendering their Pacific Numerix stock certificates to Ansoft for
cancellation, together with the letter of transmittal and any other documents
required by the exchange agent, the holders of Pacific Numerix stock
certificates will be entitled to receive a certificate representing that number
of whole shares of Ansoft common stock which that holder has the right to
receive. Until surrendered to the exchange agent, outstanding Pacific Numerix
stock certificates will be deemed from and after the effective time to evidence
only the right to receive the number of full shares of Ansoft common stock into
which the shares of Pacific Numerix common stock have converted.

                                       26
<PAGE>   34

DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES

     Until each Pacific Numerix stockholder surrenders his Pacific Numerix stock
certificate in exchange for an Ansoft stock certificate, that stockholder will
not receive any dividends or other distributions declared or made by Ansoft
after the effective time of the merger. However, once that stockholder
surrenders his or her Pacific Numerix stock certificate to the exchange agent,
he or she will receive (1) an Ansoft stock certificate, (2) cash as payment for
fractional shares, and (3) cash, without interest, as payment for any dividends
or other distributions declared or made by Ansoft after the effective time of
the merger.

NO FRACTIONAL SHARES

     No fractional shares of Ansoft common stock will be issued because of the
merger. Instead, each Pacific Numerix stockholder who would be entitled to a
fractional share of Ansoft common stock will receive cash. The amount of cash to
be received by such Pacific Numerix stockholder will be determined as described
above in the Section "Conversion of Shares in the Merger."

DIRECTOR AND OFFICER INDEMNIFICATION

     From and after the effective time of the merger, Pacific Numerix will
continue to fulfill its obligations under any indemnification agreements with
its directors and officers that existed as of the effective time of the merger
and any indemnification provisions under Pacific Numerix's organizational
documents that were in effect on the date of the merger agreement.

     The articles of incorporation and bylaws of Pacific Numerix following the
merger will contain provisions relating to exculpation and indemnification that
are at least as favorable to the indemnified directors and officers as those
contained in Pacific Numerix's organizational documents that were in effect on
the date of the merger agreement. These indemnification provisions will not be
amended, repealed or otherwise modified for three years after the effective time
of the merger if such modification would adversely affect the rights of
individuals who were directors, officers, employees or agents of Pacific Numerix
immediately prior to the effective time of the merger, unless such modification
is required by law.

CONDITIONS TO THE MERGER

     The obligations of Ansoft and Pacific Numerix to effect the merger are
subject to the satisfaction of the following conditions:

     -- Pacific Numerix's stockholders approve the merger;

     -- the Commission declares the registration statement effective and no stop
        order suspending the effectiveness of the registration statement shall
        have been issued and no proceeding for that purpose, and no similar
        proceeding in respect of this document, shall have been initiated or
        threatened in writing by the Commission;

<PAGE>   35

        and which makes the merger illegal or otherwise prohibits consummation
        of the merger;

     If any material condition is waived, Ansoft and Pacific Numerix will amend
this document and resolicit the vote of Pacific Numerix's stockholders holders.

TERMINATION

     The merger agreement may be terminated at any time prior to the effective
time of the merger, whether before or after the requisite approval of the
stockholders of Pacific Numerix has been obtained:

     -- by mutual consent authorized by the boards of both Ansoft and Pacific
        Numerix;

     -- by either Pacific Numerix or Ansoft if a governmental entity shall have
        issued an order, decree or ruling or taken any other action which
        permanently restrains, enjoins or otherwise prohibits the merger; or

     -- by either Pacific Numerix or Ansoft if the required approval of Pacific
        Numerix's stockholders is not obtained, although the right to terminate
        the merger agreement shall not be available to Pacific Numerix if the
        failure to obtain stockholder approval shall have been caused by Pacific
        Numerix in an action or failure to act that constitutes a material
        breach by Pacific Numerix of the merger agreement.

TERMINATION FEE AND EXPENSES

     Except as set forth below, all fees and expenses incurred in connection
with the merger agreement and the merger shall be paid by the party incurring
such expenses, whether or not the merger is consummated.

AMENDMENT; WAIVER

     Subject to a applicable law, the merger agreement may be amended by the
parties at any time by execution of a written instrument signed on behalf of
Ansoft and Pacific Numerix. At any time prior to the effective time of the
merger, any party may, to the extent legally allowed:

     -- extend the time for the performance of any of the obligations or other
        acts of the other parties to the merger agreement;

     -- waive any inaccuracies in the representations and warranties made to
        such party as contained in the merger agreement or in any document
        delivered pursuant to the merger agreement; and

     -- waive compliance with any of the agreements or conditions for the
        benefit of such party as contained in the merger agreement.

                       COMPARATIVE RIGHTS OF STOCKHOLDERS

     Pacific Numerix is currently a Nevada corporation, and the rights of
Pacific Numerix's stockholders are governed by Pacific Numerix's articles of
incorporation, bylaws and Nevada law. Ansoft is currently a Delaware
corporation, and the rights of Ansoft's stockholders are governed by Ansoft's
certificate of incorporation, bylaws and Delaware law.

     Currently, the rights and privileges of Pacific Numerix's stockholders are,
in many ways, comparable to those of stockholders of Ansoft. Despite the
similarities, however, there are differences. The following is a summary of the
material differences between the rights of Pacific Numerix's stockholders and
the rights of Ansoft's stockholders as of the date of this proxy
statement/prospectus. It is not practical to summarize all of the differences
between Nevada law and Delaware law here. Therefore, you are advised to review
Nevada Law, Delaware Law, the common law, Ansoft's Delaware certificate of
incorporation and bylaws, and Pacific Numerix's Nevada articles of incorporation
and bylaws. These documents are available as described under "Where You Can Find
More Information" on page 107.

DELAWARE LAW AND NEVADA LAW AND CURRENT GOVERNING DOCUMENTS OF ANSOFT AND
PACIFIC NUMERIX, RESPECTIVELY

     Under Pacific Numerix's bylaws, the number of directors shall be at least 5
and no more than 20. Under Ansoft's bylaws, the number of directors shall be at
least 1. The number of directors shall be fixed by the board of directors.
Currently, Pacific Numerix has 2 directors with 4 vacancies, and Ansoft has 6.

CUMULATIVE VOTING

     Under Nevada corporate law, stockholders of a Nevada corporation do not
have cumulative voting rights in the election of directors unless the articles
of incorporation so provides. Pacific Numerix's Articles of Incorporation does
not provide for cumulative voting.

     Under Delaware corporate law, stockholders of a Delaware corporation do not
have cumulative voting rights in the election of directors unless the
certificate of incorporation so provides. Ansoft's Certificate of Incorporation
does not provide for cumulative voting.

SPECIAL MEETINGS OF STOCKHOLDERS

     Nevada law does not specifically address who may call special meetings of
stockholders. The Pacific Numerix bylaws provide that special meetings of
shareholders may be called by the President, by the directors on written request
of two members of the board of directors or by the President at the request of
stockholders owning not less than 50% of the outstanding voting shares of the
corporation.

     Under Delaware law, a special meeting of stockholders may be called by the
board of directors or any other person authorized to do so in the corporation's
certificate of incorporation or bylaws. The Ansoft bylaws provide that special
meetings of stockholders may be called by the board, the President, or by the
holders of shares entitled to cast not less than 20% of the votes at such
meeting.

STOCKHOLDER CONSENT IN LIEU OF MEETING

     Nevada corporate law states that, unless otherwise provided in a
corporation's articles of incorporation or bylaws, any action required or
permitted to be taken at a meeting of the stockholders may be taken without a
meeting if a written consent thereto is signed by stockholders holding at least
a majority of the voting power, except that if a different proportion of voting
power is required for such an action at a meeting, then that proportion of
written consent is required. Pacific Numerix's bylaws provide for such action by
partial written consent.

     Except as otherwise provided by the certificate of incorporation (and
Ansoft's certificate of incorporation is silent on this issue) Delaware
corporate law permits any action required or permitted to be taken at any
meeting of a corporation's stockholders to be taken without a meeting, without a
prior notice and without a vote, upon the written consent of stockholders who
would have been entitled to cast the minimum number of votes necessary to
authorize such action at a meeting of stockholders at which all stockholders
entitled to vote were present and voting.

SPECIAL TRANSACTIONS

     Under Nevada corporate law, unless a greater vote is specified in the
certificate of incorporation, the affirmative vote of a majority of the votes
cast by stockholders entitled to vote on the matter is required to approve,
among other things:

     - certain amendments to a Nevada corporation's articles of incorporation;

     - the sale or other disposition of all or substantially all of a
       corporation's assets; or

     - the merger or consolidation of the corporation with another corporation.

     Pacific Numerix's Articles of Incorporation does not contain provisions
specifying a greater vote requirement. Under Pacific Numerix's Articles of
Incorporation, the holders of common stock are entitled to one vote per share
and the holders of preferred are currently entitled to 1 vote per share of
preferred stock. The holders of the outstanding shares of a class or series are
entitled to vote as a class upon any proposed amendment to the articles of
incorporation, whether or not entitled to vote thereon by the provisions of the
corporation's articles of incorporation, if the amendment would increase or
decrease the aggregate number of authorized shares of such series or class,
increase or decrease the par value of the shares of such class or series or
alter or change the powers, preferences or specific rights of the shares of such
series or class so as to adversely affect them.

     Under Delaware corporate law, unless otherwise specified in the certificate
of incorporation:

     - an amendment to the certificate of incorporation;

     - the voluntary dissolution of the corporation;

     - a sale or other disposition of all or substantially all of the assets of
       a corporation; or

     - a merger or consolidation of a stock corporation with another stock
       corporation, requires the affirmative vote of a majority of the
       outstanding stock entitled to vote thereon.

     Ansoft's Certificate of Incorporation does not contain any provisions
specifying a greater vote requirement.

APPRAISAL/DISSENTERS RIGHTS

     Stockholders of a Nevada corporation who dissent from a merger,
consolidation, sale of all or substantially all of the corporation's assets or
certain other corporate transactions are generally entitled to appraisal rights.
No statutory right of appraisal exists, however, where the stock of the Nevada
corporation is (1) listed on a national securities exchange, (2) included in the
national market system by the National Association of Securities Dealers, Inc.,
or (3) is held of record by at least 2,000 holders, unless certain other
exceptions apply.

     Stockholders of a Delaware corporation who dissent from a merger or
consolidation of the corporation may be entitled to appraisal rights.
Stockholders have the right to dissent from such corporate actions and to obtain
payment of the fair value of their shares. There are no statutory rights of
appraisal with respect to stockholders of a corporation who meet the following
conditions:

     (1) The shares held by the stockholders must either be:

        - listed on a national securities exchange or designated as a national
          market system security on an interdealer quotation system by the
          National Association of Securities Dealers, Inc., or

        - held of record by more than 2,000 stockholders,

     (2) Such stockholders must receive either:

        - shares of stock or depository receipts of the corporation surviving or
          resulting from the merger or consolidation, or

        - shares of stock or depository receipts of any other corporation, and

     (3) At the effective date of the merger or consolidation the stock or
depository receipts received by the stockholders must be either:

        - listed on a national securities exchange or designated as a national
          market system security on an interdealer quotation system by the
          National Association of Securities Dealers, Inc., or

        - held of record by more than 2,000 stockholders (or cash in lieu of
          fractional share interests therein).

     Ansoft stockholders are not entitled to appraisal rights because they have
no right to vote on the proposed merger.

LIMITATION OF LIABILITY OF DIRECTORS AND INDEMNIFICATION

     Nevada law allows a corporation, through its articles of incorporation, to
limit or eliminate the personal liability of directors and officers to the
corporation and its stockholders for damages for breach of fiduciary duty.
However, this provision excludes any limitation on liability for acts or
omissions which involve intentional misconduct, fraud or a

                                       32
<PAGE>   40

knowing violation of law or the unlawful payment of a dividend or other
distribution on the corporation's capital stock, or the unlawful purchase of its
capital stock.

     The General Corporation Law of Nevada provides that a corporation may
indemnify any person made a party or threatened to be made a party to any type
of proceedings, other than certain actions by or in right of the corporation,
because he or she is or was a director, officer, employee or agent of the
corporation or was serving at the request of the corporation as a director,
officer, employee or agent of another corporation, against expenses, judgments,
fines and amounts paid in settlement actually and reasonably incurred in
connection with such proceeding if such person acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the best
interests of the corporation; or in a criminal proceeding, if he or she had no
reasonable cause to believe his or her conduct was unlawful. Expenses incurred
by an officer or director, or other employees or agents as deemed appropriate by
the board of directors, in defending civil or criminal proceedings may be paid
by the corporation in advance of the final disposition of such proceeding upon
receipt of an undertaking by or on behalf of such person to repay such amount if
it is ultimately determined that such person is not entitled to be indemnified
by the corporation. To indemnify a party, the corporation must determine that
the party met the applicable standards of conduct. The Pacific Numerix Articles
of Incorporation and bylaws provide for limitation of liability and
indemnification to the fullest extent possible under Nevada law.

     Under Delaware law, a corporation may include in its certificate of
incorporation a provision that would, subject to the limitations described
below, eliminate or limit directors' liability for monetary damages for breaches
of their fiduciary duty of care. Under the Delaware law, a director's liability
cannot be eliminated or limited:

     - for breaches of the duty of loyalty,

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law,

     - for the payment of unlawful dividends or expenditure of funds or unlawful
       stock purchase or redemptions, or

     - for transactions from which such director derived an improper personal
       benefit.

     Ansoft's Certificate of Incorporation contains provisions limiting a
director's liability to the fullest extent permitted by Delaware law. Delaware
corporate law also provides Ansoft has broad powers to indemnify its directors
and officers against liabilities they may incur in such capacities, including
liabilities under the Securities Act. Ansoft's Certificate of Incorporation
provides that Ansoft will indemnify its directors and executive officers and may
indemnify other officers to the fullest extent permitted by law. The bylaws also
authorize Ansoft to advance litigation expenses in the case of certain actions,
against an undertaking by the indemnified party to repay such advances if it is
ultimately determined that the indemnified party is not entitled to
indemnification.

INTERESTED STOCKHOLDERS TRANSACTIONS

     Sections 78.411 to 78.444 of the General Corporation Law of Nevada,
inclusive, restrict the ability of a resident domestic corporation to engage in
any combination with an interested stockholder for three years after the
interested stockholder's date of acquiring the shares that cause such
stockholder to become an interested stockholder unless the

                                       33
<PAGE>   41

combination or the purchase of shares by the interested stockholder on the
interested stockholder's date of acquiring the shares that cause such
stockholder to become an interested stockholder is approved by the board of
directors of the resident domestic corporation before that date. If the
combination was not previously approved, the interested stockholder may effect a
combination after the three-year period only if such stockholder receives
approval from a majority of the disinterested shares or the offer meets various
fair price criteria. For purposes of the foregoing provisions, "resident
domestic corporation" means a Nevada corporation that has 200 or more
stockholders and "interested stockholder" means any person, other than the
resident domestic corporation or its subsidiaries, who is:

     - the beneficial owner, directly or indirectly, of ten percent or more of
       the voting power of the outstanding voting shares of the resident
       domestic corporation; or

     - an affiliate or associate of the resident domestic corporation and at any
       time within three years immediately before the date in question was the
       beneficial owner, directly or indirectly, of ten percent or more of the
       voting power of the outstanding shares of the resident domestic
       corporation.

     The above provisions do not apply to any combination involving a resident
domestic corporation:

     - whose original articles of incorporation expressly elect not to be
       governed by Sections 78.411 to 78.444 of Nevada law, inclusive;

     - which does not, as of the date of acquiring shares, have a class of
       voting shares registered with the SEC under Section 12 of the Securities
       Act, unless the corporation's articles of incorporation provide
       otherwise;

     - whose articles of incorporation were amended to provide that the
       corporation is subject to the above provisions and which did not have a
       class of voting shares registered with the SEC under Section 12 of the
       Securities Act on the effective date of such amendment, if the
       combination is with an interested stockholder whose date of acquiring
       shares is before the effective date of such amendment; or

     - that amends its articles of incorporation, approved by a majority of the
       disinterested shares, to expressly elect not to be governed by Sections
       78.411 to 78.444 of Nevada law, inclusive. Such an amendment, however,
       would not become effective until eighteen months after its passage and
       would apply only to stock acquisitions occurring after the effective date
       of the amendment.

     Pacific Numerix does not have a class of voting securities registered with
the SEC under Section 12 of the Securities Act and its articles do not state
that it expressly elects to be governed by Sections 78.411 to 78.444.

     A provision of Delaware law prohibits certain transactions between a
Delaware corporation and an "interested stockholder." An "interested
stockholder" for purposes of this Delaware law provision is a stockholder that
is directly or indirectly a beneficial owner of fifteen percent or more of the
voting power of the outstanding voting stock of a Delaware corporation, or its
affiliate or associate. This provision prohibits certain business

                                       34
<PAGE>   42

combinations between an interested stockholder and a corporation for a period of
three years after the date the interested stockholder acquired its stock unless:

     - the business combination is approved by the corporation's board of
       directors prior to the stock acquisition date;

     - the interested stockholder acquired at least 85% of the voting stock of
       the corporation in the transaction in which such stockholder became an
       interested stockholder; or

     - the business combination is approved by a majority of the board of
       directors and the affirmative vote of two-thirds of disinterested
       stockholders.

DIVIDENDS

     Except as otherwise provided in Pacific Numerix's Articles of
Incorporation, Nevada law authorizes the corporation to make distributions to
its stockholders, unless:

     - the corporation would not be able to pay its debts as they become due in
       the usual course of business, or

     - the corporation's total assets would be less than the sum of its total
       liabilities plus any amount owed, if the corporation would be dissolved
       at the time of distribution, to stockholders with preferential rights
       superior to those receiving the distribution.

     Pacific Numerix's Articles of Incorporation do not contain any further
restrictions on the declaration or payment of dividends. The holders of the then
outstanding preferred and common stock are entitled to receive on an equal share
for share basis, the dividends declared by the board.

     Delaware corporate law generally limits dividends to Ansoft to an amount
equal to the excess of the net assets of Ansoft (the amount by which total
assets exceed total liabilities) over its statutory capital, or if there is no
such excess, to its net profits for the current and/or immediately preceding
fiscal year. The board of directors has the authority to declare and pay
dividends.

BYLAWS

     Under Nevada law, subject to any bylaws adopted by the stockholders, the
directors may make the bylaws of the corporation. Under the Pacific Numerix
bylaws, the bylaws may be altered, amended or repealed and new bylaws adopted by
a vote of a majority of the board.

     Under Delaware corporate law, the stockholders of a Delaware corporation
have the power to adopt, amend, or repeal the corporation's bylaws, unless such
powers also are conferred in the certificate of incorporation to the board of
directors. The Certificate of Incorporation of Ansoft confers the power to alter
or repeal the bylaws to the board by action of the full board.

                   INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendation of Pacific Numerix's board of directors
with respect to the merger, you should be aware that members of Pacific
Numerix's board of directors and management have interests in the merger that
are in addition to your interests as a holder of Pacific Numerix common stock
generally. Pacific Numerix's board of directors was aware of these interests and
considered them in approving the merger. The board of directors of Pacific
Numerix is comprised of Zolton Cendes and Nicholas Csendes, both officers and
directors of Ansoft.

     Additionally, Ansoft acquired approximately 75% of the voting power of
Pacific Numerix in a transaction with certain major stockholders of Pacific
Numerix that was consummated in April 1999. A brief summary of this transaction
is described on page 20 of this prospectus/proxy statement.

BUSINESS

GENERAL

     Ansoft develops, markets and supports electronic design automation ("EDA")
software based on fundamental electromagnetic principles. Such software is used
by engineers in the design of high performance electronic devices and systems,
such as cellular phones, communications systems, computer circuit boards and
motors. As the marketplace demands higher levels of system performance and
miniaturization, the need to model accurately the electromagnetic interaction in
communications, computer devices and electromechanical components and systems is
becoming increasingly important, yet traditional EDA tools do not provide
accurate modeling of electromagnetic interaction. By using the our software,
companies can more easily predict electromagnetic interaction in such systems
and components, thus reducing time-to-market and simultaneously lowering design
and manufacturing costs. Our products are used by design engineers in a wide
range of industries, particularly the rapidly evolving wireless communications
and RF (radio frequency) markets as well as the semiconductor, computer,
automotive and consumer electronics industries.

ANSOFT STRATEGY

     Our objective is to become a leading worldwide supplier of EDA software.
Using its proprietary electromagnetic technology as a primary competitive
advantage, we pursue our objective by leveraging our technology leadership;
capitalizing on the growing need for electromagnetic analysis in increasingly
compact and complex electronic and electromechanical components and systems
operating at higher speeds; and expanding its broad range of product
applications to address emerging customer design requirements

COMPETITION

     The EDA software industry is highly competitive and is characterized by
continuing advances in products and technologies. In general, competition comes
from major EDA vendors, many of which have a longer operating history,
significantly greater financial, technical and marketing resources, greater name
recognition and a larger installed customer base than Ansoft. Ansoft competes
directly with certain major EDA vendors and privately-held companies which also
provide products based on electromagnetic principles

                                       46
<PAGE>   54

derived from Maxwell's Equations. There can be no assurance that the major EDA
vendors and other EDA companies will not expand and develop new products in the
electromagnetics-based EDA market. Ansoft also competes, on a limited basis,
with the internal development groups of its existing and potential customers,
many of whom design and develop customized design tools for their particular
needs. In addition, the EDA industry has become increasingly concentrated in
recent years as a result of acquisitions, and further concentration within the
EDA industry could result in increased competition for Ansoft. Ansoft's software
products currently compete with certain software offerings from Hewlett-Packard
Corporation ("HP"). In 1989, Ansoft entered into a distribution arrangement with
Hewlett-Packard Corporation ("HP") under which HP formerly distributed Ansoft's
HFSS product on an exclusive basis (the "HP Agreement"). The HP Agreement has
since expired, and HP has no right to distribute Ansoft's HFSS product. Ansoft
currently sells HFSS through its own sales force and other distributors. There
can be no certainty that Ansoft will be able to compete successfully against HP.
The failure of Ansoft to compete successfully against current and future
competitors would have a material adverse effect on Ansoft's business, operating
results and financial condition. Ansoft believes that its current products
compete effectively on the basis of product functionality, solution speed and
accuracy, reliability, price, ease of use and technical support for applications
which require accurate modeling of electromagnetic interaction. However, there
is no assurance that Ansoft will not face competitive technologies that could
hinder its future prospects.

PROPRIETARY RIGHTS

     Ansoft is heavily dependent on its proprietary software technology. We rely
on a combination of non-competition and confidentiality agreements with our
employees, license agreements, copyrights, trademarks and trade secret laws to
establish and protect proprietary rights to Ansoft technology. Ansoft does not
hold any patents. All Ansoft software is shipped with a security lock which
limits software access to authorized users. In addition, we do not license or
release its source code. Effective copyright and trade secret protection of our

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

     The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains certain forward-looking statements that
involve substantial risks and uncertainties. When used in this Prospectus, the
words "anticipate," "plan,"

                                       50
<PAGE>   58

"believe," "estimate," "expect" and similar expressions as they relate to Ansoft
or its management are intended to identify such forward-looking statements.
Ansoft's actual results, performance or achievements could differ materially
from the results expressed in, or implied by, these forward-looking statements.
Factors that could cause or contribute to such differences include those
discussed in "Risk Factors" section included in Ansoft's report on Form 10-K for
the fiscal year ended April 30, 1999.

OVERVIEW

     Ansoft develops, markets and supports electronic design automation ("EDA")
software based on fundamental electromagnetic principles. Ansoft's software is
used by engineers in the design of high performance electronic devices and
systems, such as cellular phones, communications systems, computer circuit
boards and motors. As the marketplace demands higher levels of system
performance and miniaturization, the need to model accurately the
electromagnetic interaction in communications, computer devices and
electromechanical components and systems is becoming increasingly important, yet
traditional EDA tools do not provide accurate modeling of electromagnetic
interaction. By using Ansoft's software, companies can more easily predict
electromagnetic interaction in such systems and components, thus reducing time
to market and simultaneously lowering design and manufacturing costs. Ansoft's
products are used by design engineers in a wide range of industries,
particularly the rapidly evolving wireless communications and RF (radio
frequency) markets as well as the semiconductor, computer, automotive and
consumer electronics industries.

     License revenue consists principally of revenue from the licensing of
Ansoft's software and is generally recognized when the software has been shipped
and there are no significant remaining obligations. Service revenue consists of
maintenance fees for providing system updates, user documentation and technical
support for software products, and is recognized ratably over the term of the
maintenance agreement. Other revenue consists primarily of revenue earned on
development contracts with government-sponsored entities. Revenue under these
arrangements is recognized as the service is performed.

     Effective April 28, 1999, Ansoft acquired a majority interest in Pacific
Numerix. Effective July 24, 1996, April 9, 1997 and August 8, 1997, Ansoft
acquired the Electronic Business Unit of MacNeal Schwendler Company, Compact
Software, Inc., and Boulder Microwave Technologies, respectively. The cost of
these acquisitions has been allocated on the basis of the estimated fair value
of the assets acquired and the liabilities assumed. The acquisitions have been
accounted for as purchases, and their respective financial results have been
included in the accompanying consolidated financial statements since the date of
their respective acquisitions.

COMPARISON OF THE THREE MONTHS ENDED JULY 31, 1999 AND 1998

     REVENUE.  Total revenue in the three-month period ended July 31, 1999
increased 34% to $6.9 million from $5.2 million in the comparable period of the
preceding fiscal year. License revenue during the three-month period ended July
31, 1999 increased 64% to $5.3 million from $3.2 million during the comparable
period in the prior fiscal year. The increase is primarily attributable to
strong demand for our HFSS product, and to a recovery of sales in the
Asia-Pacific region. Service and other revenue decreased by 16% due to the
completion of a research and development cost-sharing contract during 1998.

     International revenue accounted for 52% and 51% of Ansoft's total product
revenue in the three-month period ended July 31, 1999 and 1998, respectively.

     SALES AND MARKETING EXPENSES.  Sales and marketing expenses consist of
salaries, commissions paid to internal sales and marketing personnel and
international distributors, promotional costs and related operating expenses.
Sales and marketing expenses increased by 8% to $4.6 million in the three-month
period ended July 31, 1999, as compared to $4.3 million in the same period in
the previous fiscal year. The increase is attributable to an

                                       52
<PAGE>   60

increase in Ansoft's sales force as a result of the acquisitions as well as
increased marketing efforts, including advertising in trade publications and
increased participation in industry trade shows. Sales and marketing expenses
represented 66% and 83% of total revenue in the three-month period ended July
31, 1999 and 1998, respectively. Ansoft expects that sales and marketing
expenses will decrease as a percentage of sales although increase in absolute
dollars in future periods.

     RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
include all costs associated with the development of new products and
enhancements to existing products. Research and development expenses for the
three-month period ended July 31, 1999 increased 15% to $2.4 million, as
compared to $2.1 million for the same period in the previous fiscal year. The
increase is due to increased research and development personnel primarily as a
result of the PNC acquisition. Research and development expense represented 34%
and 40% of total revenue in the three-month period ended July 31, 1999 and 1998,
respectively. Ansoft anticipates that research and development expenses will
decrease as a percentage of sales although increase in absolute dollars in
future periods.

     GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
for the three-month period ended July 31, 1999 increased 27% to $807,000, as
compared to $635,000 for the same period in the previous fiscal year. The
increase is due to additional costs required to support the increase in
operations, including the hiring of additional administrative personnel. General
and administrative expenses represented 12% of total revenue in the three-month
period ended July 31, 1999 and 1998. Ansoft anticipates that general and
administrative expenses will decrease as a percentage of sales although increase
in absolute dollars in future periods.

     AMORTIZATION EXPENSE.  Amortization expense for the three-month period
ended July 31, 1999 increased to $642,000, as compared to $422,000 for the same
period in the previous fiscal year. The increase is due to the amortization of
the additional intangible assets acquired during fiscal 1999.

     OTHER INCOME.  Other income for the three-month period ended July 31, 1999
was $390,000, comparable to $379,000 reported for the same period in the
previous fiscal year.

     INCOME TAXES.  In the three-month period ended July 31, 1999, Ansoft
recorded a net income tax benefit of $225,000 resulting from the recognition of
deferred tax assets in accordance with the Financial Accounting Standards
Board's SFAS No. 109, "Accounting for Income Taxes." Ansoft's net deferred tax
asset of $3.3 million as of July 31, 1999, consists primarily of net operating
loss carryforwards for federal income tax purposes, which are available to
offset future taxable income, and expire in increments beginning in April 2004,
through April 2019. Valuation allowances are established when necessary to
reduce deferred tax assets to the amounts expected to be realized.

YEAR ENDED APRIL 30, 1999 COMPARED WITH YEAR ENDED APRIL 30, 1998

     REVENUE.  Total revenue for the year ended April 30, 1999 decreased 7% to
$24.5 million from $26.3 million in the previous fiscal year. The decrease in
total revenue is primarily attributable to a decrease in service revenue due to
the completion of a research and development cost sharing contract during 1998.
License revenue during the year ended April 30, 1999 decreased 11% to $17.8
million from $20.0 million during the previous fiscal year. Service and other
revenue increased by 5% to $6.6 million for the year ended April 30, 1999, as
compared with $6.3 million in the previous year. The increase in service

                                       53
<PAGE>   61

and other revenue is attributable to the continued growth of the installed base
of customers and increased focus on marketing annual maintenance agreements.
This increase was reduced by a decrease in revenue recognized under research and
development cost sharing agreements.

     International revenue, principally from Asia, accounted for 52% and 48% of
our total product revenue in the years ended April 30, 1999 and 1998,
respectively. Ansoft's future international sales may be subject to additional
risks associated with international operations, including currency exchange
fluctuations, tariff regulations and requirements for export, which licenses may
on occasion be delayed or difficult to obtain.

     SALES AND MARKETING EXPENSES.  Sales and marketing expenses increased by
35% to $17.1 million in the year ended April 30, 1999, as compared to $12.6
million in the previous fiscal year. The increase is primarily attributable to
Ansoft's shift in its distribution model to the use of direct sales personnel in
Asia and other foreign markets, as well as increased marketing efforts,
including advertising in trade publications and increased participation in
industry trade shows. Sales and marketing expenses represented 70% and 48% of
total revenue in the years ended April 30, 1999 and 1998, respectively. Ansoft
expects to increase sales and marketing expenditures both domestically and
internationally as part of its continuing effort to expand its markets,
introduce new products, build marketing staff and programs and expand its
international presence. Ansoft expects that sales and marketing expenses will
decrease as a percentage of sales although increase in absolute dollars in
future periods.

     RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses for
the year ended April 30, 1999 increased 15% to $8.4 million, as compared to $7.3
million for the previous fiscal year. The increase is due to increased research
and development personnel primarily as a result of the acquisitions. Research
and development expenses represented 34% and 28% of total revenue in the years
ended April 30, 1999 and 1998, respectively. Ansoft anticipates that research
and development expenses will increase in absolute dollars in future periods.

     GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
for the year ended April 30, 1999 increased 26% to $2.9 million, as compared to
$2.3 million for the previous fiscal year. The increase is due to additional
costs required to support the increase in operations, including the hiring of
additional administrative personnel. General and administrative expenses
represented 12% and 9% of total revenue in the years ended April 30, 1999 and
1998, respectively. The Company anticipates that general and administrative
expenses will increase in absolute dollars in future periods.

     AMORTIZATION EXPENSE.  Amortization expense for the year ended April 30,
1999 increased to $1.7 million, as compared to $1.5 million for the previous
fiscal year. The increase is due to recording amortization of additional
intangible assets acquired in recent years.

     INTEREST (NET).  Interest income (net) for the year ended April 30, 1999
increased to $1.6 million, compared to $549,000 for the previous fiscal year.
Interest income increased due to the higher net investment balance made
available from the proceeds from the public offering of 2.3 million shares in
March of 1998.

     INCOME TAXES.  In the year ended April 30, 1999, Ansoft recorded a net
income tax benefit of $1.2 million, resulting from the recognition of deferred
tax assets in accordance with the Financial Accounting Standards Board's SFAS
No. 109, "Accounting for Income

                                       54

Taxes." Ansoft's net deferred tax asset of $3.1 million as of April 30, 1999,
consists primarily of net operating loss carry forwards for federal income tax
purposes, which are available to offset future taxable income, and expire in
increments beginning in April 2004, through April 2012. Valuation allowances are
established when necessary to reduce deferred tax assets to the amounts expected
to be realized.

YEAR ENDED APRIL 30, 1998 COMPARED WITH YEAR ENDED APRIL 30, 1997

     REVENUE.  Total revenue for the year ended April 30, 1998 increased 85% to
$26.3 million from $14.2 million in the previous fiscal year, primarily due to
increases in license revenue. License revenue during the year ended April 30,
1999 increased 67% to $20.0 million from $12.0 million during the previous
fiscal year. The growth of license revenue is attributable to the continued
increase in sales of existing Ansoft products as well as sales of the expanded
suite of products offered by Ansoft as a result of the acquisitions. Service and
other revenue increased by 182% to $6.3 million for the year ended April 30,
1998, as compared with $2.2 million in the previous year. The increase in
service and other revenue is attributable to an increase in revenue recognized
under research and development cost sharing agreements as well as the continued
growth of the installed base of customers and increased focus on marketing
annual maintenance agreements.

     International revenue, principally from Asia, accounted for 48% and 41% of
Ansoft's total product revenue in the years ended April 30, 1998 and 1997,
respectively.

     In 1989, Ansoft entered into a distribution arrangement with
Hewlett-Packard Corporation ("HP") under which HP formerly distributed the
Company's HFSS product on an exclusive basis (the "HP Agreement"). The HP
Agreement has since expired, and HP has no right to distribute Ansoft's HFSS 4.0
product. Ansoft currently sells the latest version of its HFSS product, Ansoft
HFSS 6.0, through its own sales force and other distributors. Revenue from the
HP Agreement accounted for 3% and 12% of total revenue in the years ended April
30, 1998 and 1997, respectively.

     SALES AND MARKETING EXPENSES.  Sales and marketing expenses increased by
59% to $12.6 million in the year ended April 30, 1998, as compared to $7.9
million in the previous fiscal year. The increase is attributable to an increase
in Ansoft's sales force as a result of the acquisitions as well as increased
marketing efforts, including advertising in trade publications and increased
participation in industry trade shows. Sales and marketing expenses represented
48% and 56% of total revenue in the years ended April 30, 1998 and 1997,
respectively.

     RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses for
the year ended April 30, 1998 increased 144% to $7.3 million, as compared to
$3.0 million for the previous fiscal year. The increase is due to increased
research and development personnel primarily as a result of the acquisitions.
Research and development expenses represented 28% and 22% of total revenue in
the years ended April 30, 1998 and 1997, respectively.

     GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
for the year ended April 30, 1998 increased 41% to $2.3 million, as compared to
$1.6 million for the previous fiscal year. The increase is due to additional
costs required to support the increase in operations, including the hiring of
additional administrative personnel. General and administrative expenses
represented 9% and 12% of total revenue in the years ended April 30, 1998 and
1997, respectively.

                                       55
<PAGE>   63

     AMORTIZATION EXPENSE.  Amortization expense for the year ended April 30,
1998 increased to $1.5 million, as compared to $407,000 for the previous fiscal
year. The increase is due to recording amortization of intangible assets
acquired in Fiscal 1997 for a full fiscal year and to recording amortization of
the additional intangible assets acquired during fiscal 1998.

     INTEREST (NET).  Interest income for the year ended April 30, 1999
decreased to $709,000, compared to $902,000 for the previous fiscal year.
Interest income decreased due to the use of cash in partial payment for the
fiscal 1998 and fiscal 1997 acquisitions. Interest expense for the year ended
April 30, 1998 decreased to $160,000, compared to $220,000 for the previous
fiscal year. Interest expense decreased due to decreased borrowing.

     INCOME TAXES.  In the year ended April 30, 1999, Ansoft recorded a net
income tax benefit of $1.0 million, resulting from the recognition of previously
unrecognized deferred tax assets in accordance with the Financial Accounting
Standards Board's SFAS No. 109, "Accounting for Income Taxes."

QUARTERLY RESULTS OF OPERATIONS

     The following table presents unaudited quarterly results in dollar amounts
and as a percentage of total revenue for each quarter of fiscal 1999 and fiscal
1998. The information has been prepared on a basis consistent with Ansoft's
annual consolidated financial statements and, in the opinion of management,
contains all adjustments, consisting only of normal recurring adjustments,
necessary for a fair presentation of the information for such periods. Ansoft's
quarterly results have been in the past, and may be in the future, subject to
fluctuations due to increased competition, the timing of new product
announcements, changes in pricing policies by Ansoft or its competitors, market
acceptance of new and enhanced versions of Ansoft's products and the size and
timing of significant licenses. Ansoft believes that results of operations for
the interim periods are not necessarily indicative of the results to be expected
for any future period. Ansoft's business has been seasonal, with revenues in the
first fiscal quarter typically lower than the fourth quarter of the preceding
fiscal year.

LIQUIDITY AND CAPITAL RESOURCES

     As of July 31, 1999, Ansoft had $2.7 million in cash and cash equivalents
and working capital of $15.6 million. Net cash provided by (used in) operating
activities was $691,000 and $(735,000) in the three months ended July 31, 1999
and 1998, respectively. Net cash provided by (used in) investing activities was
$(1.4) million and $(14.9) million in the three months ended July 31, 1999 and
1998, respectively. Capital expenditures, consisting primarily of purchases of
computer equipment, were $264,000 and $385,000 in the three months ended July
31, 1999 and 1998, respectively. Net cash provided by financing activities
includes cash proceeds from the issuance of Common Stock totaling $19,000 and
$57,000 in the three months ended July 31, 1999 and 1998, respectively.

     Ansoft has available a $10.0 million secured line of credit from a domestic
financial institution at an interest rate equal to LIBOR plus an applicable
margin rate. The line of credit is secured by the marketable securities held
with the institution. As of July 31, 1999, $8.5 million was the outstanding
balance on the line of credit. Ansoft believes that the available funds will be
sufficient to meet its anticipated cash needs for working capital and capital
expenditures for at least the foreseeable future. Thereafter, if cash generated
from operations is insufficient to satisfy Company's liquidity requirements,
Ansoft may seek additional funds through equity or debt financing. There can be
no assurance that additional financing will be available or that, if available,
such financing will be on terms favorable to Ansoft.

     ACQUISITIONS.  On July 24, 1996, the Company acquired the EBU for $5.6
million in cash. On April 9, 1997, the Company acquired all of the outstanding
capital stock of Compact for $3.0 million in cash and 1.3 million shares of the
Company's Common Stock. On August 11, 1997, the Company acquired Boulder by the
merger of Boulder with and into the Company, in consideration for $743,000 in
cash and 108,000 shares of the Company's Common Stock. On April 28, 1999, Ansoft
acquired a majority of the outstanding stock of Pacific Numerix for 372,000
shares and $600,000 in cash. The acquisitions were accounted for as a purchases,
and the financial results of the acquired entities have been included in the
accompanying consolidated financial statements since the respective date of the
acquisitions.

EFFECTS OF INFLATION

     To date, inflation has not had a material impact on Ansoft's consolidated
financial results.

     STATE OF READINESS.  The results of this evaluation revealed that most of
Ansoft's supported products are Year 2000 ready. Ansoft plans to offer patches
or upgrades to the supported products currently not Year 2000 ready.

     During 1998, an evaluation was done to Ansoft's internal support systems to
determine if they are Year 2000 ready to support our operations beyond the year
2000. We

                                       58
<PAGE>   66

currently uses third party software systems and applications, some of which are
not Year 2000 ready. Ansoft intends to stop using these software products or
upgrade or replace them as part of its growth plan.

     Although Ansoft intended to replace or upgrade these systems prior to June
30, 1999, the work will be extended to December 31, 1999. The failure by Ansoft
to complete such work prior to December 31, 1999 could have a material adverse
effect on our business, financial condition and operations.

     COSTS.  Ansoft does not have a project tracking system that tracks the cost
and time that its own internal employees spend on the Year 2000 project. Based
on Ansoft's assessment, the cost incurred to date has not had a material impact
to our results of operations. We expects that costs directly related to Year
2000 in excess of normal upgrade and maintenance costs would not exceed
approximately $100,000 for both costs incurred to date and future costs.
However, there is no assurance that the costs may not exceed this amount.

     RISKS.  Ansoft is requesting its vendors to provide Year 2000 compliance
certificates for all its internal support systems. However, Ansoft only intends
to perform testing on its critical internal support systems. Inoperability
related to Year 2000 problems of internal systems that are certified Year 2000
ready by the vendor and not tested by us could have an adverse impact on our
operational efficiency.

     The patches or upgrades provided by Ansoft as the remedies to make its
products Year 2000 ready may not be accepted by the customer, which could have
an adverse impact on Ansoft's business.

     Ansoft believes that the purchasing patterns of customers and potential
customers may be affected by Year 2000 issues as companies expend significant
resources to correct or patch their current software systems for Year 2000
readiness. These expenditures may result in reduced funds available to purchase
software products such as those offered by Ansoft, which could result in a
material adverse effect on our business, financial condition and results of
operation. In addition, we do not have any meaningful data as to the state of
its customers' Year 2000 readiness.

     CONTINGENCY PLANS.  Ansoft does not presently have a contingency plan for
handling Year 2000 problems that are not detected and corrected prior to their
occurrences. Upon completion of testing and implementation activities, Ansoft
will be able to assess the areas requiring contingency planning and expects to
develop appropriate planning at that time. Any failure of Ansoft to address any
unforeseen Year 2000 problems could adversely affect our business, financial
condition and results of operations.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     INTEREST RATE RISK.  Ansoft's exposure to market risk for changes in
interest rates relates primarily to its investment portfolio. Ansoft mitigates
its risk by diversifying its investments among credit quality securities and
limits the amount of credit exposure to any one issuer. Ansoft does not hedge
any interest rate exposures.

     FOREIGN CURRENCY RISK.  Ansoft transacts business in various foreign
currencies. Accordingly, Ansoft is subject to exposure from adverse movements in
foreign currency exchange rates. As of July 31, 1999, Ansoft had no hedging
contracts outstanding. Ansoft

                                       59
<PAGE>   67

assesses the need to utilize financial instruments to hedge currency exposures
on an ongoing basis.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL
DISCLOSURE

     NONE.  There has not been a change of accountants in the past 24 months nor
has any disagreement on any matter of accounting principles or practices been
reported on Form 8-K during the same period.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
Ansoft Corporation:

     We have audited the accompanying consolidated balance sheets of Ansoft
Corporation and subsidiaries as of April 30, 1999 and 1998, and the related
consolidated statements of operations, stockholders' equity and comprehensive
income, and cash flows for each of the years in the three-year period ended
April 30, 1999. These consolidated financial statements are the responsibility
of the Company's management. Our responsibility is to express an opinion on
these consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Ansoft
Corporation and subsidiaries as of April 30, 1999 and 1998, and the results of
their operations and their cash flows for each of the years in the three-year
period ended April 30, 1999, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
           (INFORMATION AS OF JULY 31, 1999 AND FOR THE PERIOD ENDED
                      JULY 31, 1999 AND 1998 IS UNAUDITED)

1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF BUSINESS

     Ansoft is a leading developer of electronic design automation ("EDA")
software. Its products are used by engineers in the design of high performance
electrical devices and systems, such as cellular phones, satellite
communications, computer circuit boards, motors and ABS braking systems.

PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

     The accompanying consolidated financial statements include the accounts of
the Company and its subsidiaries, from the date of inception or acquisition. All
intercompany transactions have been eliminated. Effective July 24, 1996, April
9, 1997 and August 8, 1997, the Company acquired the Electronic Business Unit
(the "EBU") of The MacNeal Schwendler Company ("MSC"), Compact Software Inc.
("Compact"), and Boulder Microwave Technologies, Inc. ("Boulder"), respectively.
The Company acquired the majority interest in Pacific Numerix Corporation
("Pacific Numerix") on April 28, 1999.

USE OF ESTIMATES

     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities, revenues
and expenses and disclosure of contingent assets and liabilities. The estimates
and assumptions used in the accompanying financial statements are based on
management's evaluation of the relevant facts and circumstances as of the date
of the financial statements. Actual results may differ from those estimates.

CASH EQUIVALENTS

     Cash equivalents include only highly liquid debt instruments purchased with
original maturity dates of three months or less.

MARKETABLE SECURITIES

     Marketable Securities consist of corporate bonds and government agency
issues and are classified as of April 30, 1999 and 1998 as available for sale.
Marketable securities available for sale are recorded at fair market value based
on quoted market prices and any unrecorded gains or losses are recorded as a
separate component of stockholders' equity. Costs of investments sold are
determined on the basis of specific identification.

                               ANSOFT CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

PLANT AND EQUIPMENT

     Plant and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation for financial reporting purposes is computed using
the straight-line method based upon the estimated useful lives of the assets
which range from three to seven years. Assets acquired under capital leases and
leasehold improvements are amortized over their useful life or the lease term,
as appropriate.

INTANGIBLE ASSETS

     Intangible assets consist mainly of customer lists, established workforce,
and purchased technology which are being amortized on a straight line basis over
seven, three and three years, respectively. Purchased technology represents
acquired software which has been fully developed, achieved technological
feasibility, reached commercial viability, and is generating revenue. The
carrying value of intangible assets are reviewed whenever circumstances occur
which indicate that the carrying value may not be recoverable.

REVENUE RECOGNITION

     Revenue consists primarily of fees for licenses of the Company's software
products, maintenance and customer support.

     SOFTWARE REVENUE.  Prior to May 1, 1998, the Company complied with the
American Institute of Certified Public Accountants' (AICPA) Statement of
Position (SOP) 91-1, "Software Revenue Recognition". Revenue from the sale of
software licenses was recognized after shipment of the products and fulfillment
of acceptance terms, if any, providing that no significant vendor and
post-contract support obligations remained and collection of the related
receivable was probable. Any remaining insignificant vendor or post-contract
support obligations were accrued at the time the revenue was recognized. In the
first quarter of fiscal 1999, the Company adopted the provisions of the AICPA
SOP 97-2, "Software Revenue Recognition" (SOP 97-2). SOP 97-2 generally requires
revenue earned on software arrangements involving multiple elements to be
allocated to each element based on the relative fair values of the elements. The
revenue allocated to software products generally is recognized after shipment of
the products and fulfillment of acceptance terms. The effect of adopting SOP
97-2 on May 1, 1998 was not material.

     SERVICE AND OTHER REVENUE.  Maintenance revenue is deferred and recognized
ratably over the term of the maintenance agreement, which is typically 12
months. Revenue from customer training, support and other services is recognized
as the service is performed. Other revenue consists primarily of revenue earned
on development contracts with government-sponsored entities. Revenue under these
arrangements is recognized as the service is performed.

SOFTWARE DEVELOPMENT COSTS

     In accordance with Statement of Financial Accounting Standards (SFAS) No.
86, the Company has evaluated the establishment of technological feasibility of
its various products during the development phase. Due to the dynamic changes in
the market, the

                                       67
<PAGE>   75
                               ANSOFT CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Company has concluded that it cannot determine, with any reasonable degree of
accuracy, technological feasibility until the development phase of the project
is nearly complete. The time period during which costs could be capitalized from
the point of reaching technological feasibility until the time of general
product release is generally very short and, consequently, the amounts that
could be capitalized pursuant to SFAS No. 86 are not material to the Company's
financial position or results of operations. Therefore, the Company charges all
research and development expenses to operations in the period incurred.

INCOME TAXES

     Income taxes are provided for under the provisions of SFAS No. 109,
"Accounting for Income Taxes," for all periods presented. Under the asset and
liability method of SFAS No. 109, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates expected to apply to taxable income in the years in
which those temporary differences are expected to be recovered or settled. Under
SFAS No. 109, the effect on deferred tax assets and liabilities of a change in
tax rates is recognized in income in the period that includes the enactment
date. Valuation allowances are established when necessary to reduce deferred tax
assets to the amounts expected to be realized.

NET INCOME (LOSS) PER SHARE

     Net income (loss) per share is computed using the weighted average number
of common and common equivalent shares outstanding during the period. Common
equivalent shares are not included in the per share calculations where their
inclusion would be antidilutive, except that in accordance with certain SEC
Staff Accounting Bulletins, common and common equivalent shares issued during
the 12 months preceding the initial filing of the Registration Statement for the
Company's initial public offering have been included in the calculation using
the treasury stock method as if they were outstanding for all periods presented.

     In February 1997, Statement of Financial Accounting Standards No. 128
"Earnings Per Share" ("SFAS 128") was issued by the Financial Accounting
Standards Board. SFAS 128 requires the presentation of both basic and diluted
earnings per share. Under SFAS 128, "basic earnings (loss) per share" is
calculated based upon the weighted average number of common shares actually
outstanding, and "diluted earnings per share" is calculated based upon the
weighted average number of common shares outstanding and other potential common
shares if they are dilutive. SFAS 128 was adopted in the Company's third quarter
of fiscal 1998. Prior periods have been restated to conform with SFAS 128.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

(SFAS) No. 123 "Accounting for Stock-Based Compensation." This statement permits
a company to choose either a new fair value based method of accounting for its
stock-based compensation arrangements or to comply with APB Opinion 25 intrinsic
value based method adding pro forma disclosures of net income and earnings per
share computed as if the fair value based method had been applied in the
financial statements. The Company has adopted SFAS No. 123 by retaining APB
Opinion 25 method of accounting for stock-based compensation with annual pro
forma disclosures of net income and earnings per share.

COMPREHENSIVE INCOME

     Comprehensive Income In 1997, the Financial Accounting Standards Board
(FASB) issued Statement of Financial Accounting Standards (SFAS) No. 130
"Reporting Comprehensive Income, "which was adopted by the Company in the first
quarter of fiscal 1999. SFAS No. 130 establishes rules for the reporting and
display of comprehensive income and its components; however, the adoption of
this Statement had no impact on the Company's results of operations or
stockholders' equity. SFAS No. 130 requires companies to report a new,
additional measure of income on the income state mentor to create a new
financial statement that has the new measure of income on it. "Comprehensive
income" includes foreign currency translation gains and losses and other
unrealized gains and losses that have been previously excluded from net income
and reflected instead in equity. The Company has reported the components of
comprehensive income on its consolidated statements of stockholders' equity.

2. ACQUISITIONS AND RELATED INTANGIBLE ASSETS

     On July 24, 1996, the Company acquired the EBU for $5,600 in cash. On April
9, 1997, the Company acquired all of the outstanding capital stock of Compact
for $3,000 in cash and 1,273 shares of the Company's Common Stock. On August 11,
1997, the Company acquired Boulder by the merger of Boulder with and into the
Company, in consideration for $743 in cash and 108 shares of the Company's
Common Stock. On April 28th, 1999, Ansoft acquired the majority of the
outstanding stock of Pacific Numerix for 377 shares and $600 in cash. The cost
of these acquisitions has been allocated on the basis of the estimated fair
value of the assets acquired and the liabilities assumed. The allocation of the
EBU and Compact acquisitions resulted in charges of $3,100 and $5,700 recorded,
respectively, in fiscal 1997 based on the future expected cash flows of certain
acquired in process research and development that had not reached technological
feasibility. The acquisitions have been accounted for as purchases, and their
respective financial results have been included in the accompanying consolidated
financial statements since the date of their respective acquisitions.

     The following unaudited pro forma summary presents information as if the
acquisition of Pacific Numerix occurred at the beginning of the periods
presented. The pro forma information is provided for information purposes only.
It is based on historical information and does not necessarily reflect the
actual results that would have occurred, nor is it necessarily indicative of
future results of operations of the combined enterprise.

     Options to purchase 822 shares of Common Stock were exercisable as of April
30, 1999 and options to purchase 728 shares of Common Stock were available for
future grant as of April 30, 1999.

     In addition to the options described above, the Chairman of the Board of
Directors received an option to purchase 200 shares of Common Stock at an
exercise price of $5.00 per share in April 1995. At that time, such exercise
price was considered to be above the estimated fair market value. As of April
30, 1998, all such options were still outstanding and unexercised. The options
expire ten years after the date of the grant.

     As permitted under Statement of Financial Accounting Standards No. 123
("SFAS 123"), "Accounting for Stock-Based Compensation," the Company has elected
to follow Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees" ("APB 25"), and related Interpretations, in accounting for
stock-based awards to employees. Under APB 25, because the exercise price of the
Company's employee stock options generally equals the market price of the
underlying stock on the date of grant, no compensation expense has been
recognized in the Company's consolidated financial statements during fiscal
1999, 1998 or 1997.

     Pro forma information regarding net income and earnings (loss) per share is
required by SFAS 123. This information is required to be determined as if the
Company had accounted for its employee stock options (including shares issued
under the Stock Purchase Plan, collectively called "options") granted subsequent
to April 30, 1995 under

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options that have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions, including the expected stock price
volatility. Because the Company's options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in the opinion
of management, the existing models do not necessarily provide a reliable single
measure of the fair value of its options. However, based solely on this
analysis, the weighted average estimated fair value of employee stock options
granted during 1999, 1998 and 1997 was $3.57, $5.82 and $3.94 per share,
respectively.

     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows (unaudited):

     Because the Company anticipates making additional grants and options vest
over several years, the effects on pro forma disclosures of applying SFAS 123
are not likely to be representative of the effects on pro forma disclosures of
future years. SFAS 123 is applicable only to options granted subsequent to April
30, 1995.

10. EXPORT SALES, MAJOR CUSTOMERS AND CREDIT RISK

     Export sales, principally to Asia, accounted for 52%, 48% and 41% of total
product revenue in 1999, 1998 and 1997, respectively. Included in export sales
to Asia were sales to Japan, which accounted for approximately 16%, 16% and 13%
of total revenue in fiscal 1999, 1998, and 1997, respectively. No other foreign
country accounted for more than 10% of total revenue during these periods.

     The Company entered into a distribution arrangement with Hewlett-Packard
Corporation ("HP") under which HP formerly distributed the Company's HFSS
product on an exclusive basis (the "HP Agreement"). The HP Agreement has since
expired, and HP has no right to distribute the Company's HFSS 4.0 product. The
Company currently sells the latest version of its HFSS product, Ansoft HFSS 6.0,
through its own sales force and other distributors. Revenue from the HP
Agreement accounted for 3% and 12% of total revenue in fiscal 1998 and 1997,
respectively.

     The Company markets its software products to customers throughout the world
directly and through distributors and generally does not require collateral.
However, letters of credit are obtained from certain international customers
prior to shipment. The Company performs ongoing credit evaluations of its
customers and maintains an allowance for potential credit losses. The Company
believes that it has adequately provided for credit losses.

</TABLE>

     The valuation allowance for deferred tax assets as of May 1, 1998 and 1997
was $0 and $2,857, respectively. The net change in the total valuation allowance
for the years ended April 30, 1999 and April 30, 1998 was an increase of $383
and a decrease of $2,857, respectively. Management evaluates the recoverability
of the deferred tax assets and the level of the valuation on a quarterly basis.
In assessing the realizability of the deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. Management considers the
scheduled reversal of deferred tax liabilities, projected future taxable income,
and tax planning strategies in making this assessment.

     An additional gross deferred tax benefit of $340 was generated in the year
ended April 30, 1999 with respect to unrealized losses on available for sale
securities. Since it was more likely than not that some portion, or all of, the
unrealized loss would not be realized, management placed a valuation of $340
upon this deferred tax asset, and no benefit was reported in stockholder's
equity or income.

CUSTOMERS

     Pacific Numerix has an installed base with over 100 customers in the
communications, semiconductor, computer, consumer electronics and
defense/aerospace industries. During fiscal 1998, one customer represented 10%
of total revenue. During fiscal 1997, one customer represented 25% of total
revenue. The following is a list of a representative sample of Pacific Numerix's
current worldwide end-user customers:

     Sony, IBM, Real 3D, Siemens, Sun Microsystems, Intel, Hyundai, Texas
     Instruments, Amkor Western Digital, Tandem Computer, Symbios Logic,
     Tektronix, Silicon Graphics, Rockwell, Lucent Technologies, Lsi Logic,
     Lockheed Martin, Hana Technologies, GEC Marconi, Allied Signal, Alcatel
     Network Systems Inc.

CUSTOMER SERVICE AND SUPPORT

     Sales of Pacific Numerix's software include one year of customer support
services; thereafter annual one year maintenance contracts may be purchased.
Customer support services include on-line and telephone support for design
engineers and on-site and in-house training on all products. Customers with
maintenance agreements receive all product enhancement releases without
additional charge. Product upgrades that add significant new functionality are
provided to customers for an additional fee.

     Pacific Numerix offers a variety of training programs for customers ranging
from introductory level courses to advanced training.

COMPETITION

     The electronic design automation software market in which Pacific Numerix
competes is intensely competitive and subject to rapid change. In general,
competition comes from major EDA vendors, many of which have a longer operating
history, significantly greater financial, technical and marketing resources,
greater name recognition and a larger installed customer base than Pacific
Numerix. These companies also have established relationships with current and
potential customers of Pacific Numerix. Pacific Numerix also competes, on a
limited basis, with the internal development groups of its existing and
potential customers, many of which design and develop customized design tools
for their particular needs. In addition, the EDA industry has become
increasingly concentrated in recent years as a result of acquisitions, and
further concentration within the EDA industry could result in increased
competition for Pacific Numerix. Increased competition could result in price
reductions, reduced margins or loss of market share, any of which could
seriously harm Ansoft's business, operating results or financial condition.
Pacific Numerix may be unable to compete successfully against current and future
competitors, and competitive pressures faced by Ansoft could seriously harm
Ansoft's business, operating results and financial condition.

PROPRIETARY RIGHTS

     Pacific Numerix is heavily dependent on its proprietary software
technology. Pacific Numerix relies on a combination of confidentiality
agreements with its employees, license agreements, copyrights, trademarks and
trade secret laws to establish and protect proprietary rights to Pacific Numerix
technology. Pacific Numerix does not hold any patents. All Pacific Numerix
software is shipped with a security lock which limits software access to
authorized users. In addition, Pacific Numerix does not license or release its

                                       81
<PAGE>   89

source code. Effective copyright and trade secret protection of Pacific
Numerix's proprietary technology may be unavailable or limited in certain
foreign countries.

EMPLOYEES

     As of July 31, 1999, Pacific Numerix had a total of 15 employees, including
9 in research and development, 5 in sales, marketing, and customer support
services and 1 in administration. None of Pacific Numerix's employees are
represented by a collective bargaining agreement, nor has Pacific Numerix
experienced any work stoppage. Pacific Numerix considers its relations with its
employees to be good. Many of Pacific Numerix's employees are highly skilled,
and there is no assurance that Pacific Numerix will be able to attract and
retain sufficient technical personnel in the future.

</TABLE>

SEVEN-MONTH PERIOD ENDED JULY 31, 1999 COMPARED WITH SEVEN-MONTH PERIOD ENDED
JULY 31, 1998

     REVENUE.  Total revenue for the seven-month period ended July 31, 1999
increased 36% to $1.4 million from $1.0 million in the previous comparable
period. Product revenue during this period increased 80% to $855,000 from
$474,000 during the previous comparable period. The increase in product revenue
is primarily attributable to higher sales in the Asia-Pacific region.
Maintenance revenue increased by 18% to $500,000 for the seven-month period
ended July 31, 1999, as compared with $424,000 in the previous comparable
period. The increase in maintenance revenue is attributable to the continued
growth of the installed base of customers.

     International revenue, principally from Asia, accounted for 55% and 30% of
the Company's total product revenue in the seven-month periods ended July 31,
1999 and 1998, respectively.

                                       84
<PAGE>   92

     SALES AND MARKETING EXPENSES.  Sales and marketing expenses decreased by
12% to $733,000 for the seven-month period ended July 31, 1999, as compared with
$832,000 in the previous comparable period. The decrease is primarily
attributable to the utilization of Ansoft's sales and marketing efforts to
generate revenue. Sales and marketing expenses represented 53% and 82% of total
revenue in the seven-month periods ended July 31, 1999 and 1998, respectively.

     RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses for
the seven-month period ended July 31, 1999 increased 55% to $504,000, as
compared to $326,000 in the previous comparable period. The increase is due to
increased research and development personnel primarily as a result of additional
personnel. Research and development expenses represented 36% and 32% of total
revenue in the seven-month periods ended July 31, 1999 and 1998, respectively.

     GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
for the seven-month period ended July 31, 1999 decreased 65% to $173,000, as
compared to $495,000 in the previous comparable period. The decrease is due to
the departure of executive administrative personnel during the year. General and
administrative expenses represented 13% and 48% of total revenue in the
seven-month periods ended July 31, 1999 and 1998, respectively.

     DEPRECIATION AND AMORTIZATION EXPENSE.  Depreciation and amortization
expense for the seven-month period ended July 31, 1999 increased to $282,000, as
compared to $203,000 in the previous comparable period. The increase is due to
recording amortization of previously capitalized software development costs.

     OTHER EXPENSE (NET).  Other expense consists primarily of interest expense
on the notes payable and loans payable to related parties. Other expense (net)
for the seven-month period ended July 31, 1999 decreased to $11,000, compared to
$44,000 for the previous fiscal year. Interest expense decreased due to the
lower notes payable balance during the seven-month period ended July 31, 1999.

YEAR ENDED DECEMBER 31, 1998 COMPARED WITH YEAR ENDED DECEMBER 31, 1997

     REVENUE.  Total revenue for the year ended December 31, 1998 decreased 27%
to $2.4 million from $3.3 million in the previous fiscal year. Product revenue
during the year ended December 31, 1998 decreased 45% to $1.2 million from $2.2
million during the previous fiscal year. The decrease in product revenue is
primarily attributable to lower sales in the Asia-Pacific region. Maintenance
revenue increased by 62% to $991,000 for the year ended December 31, 1998, as
compared with $613,000 in the previous year. The increase in maintenance revenue
is attributable to the continued growth of the installed base of customers.

     International revenue, principally from Asia, accounted for 26% and 52% of
the Company's total product revenue in the years ended December 31, 1998 and
1997, respectively.

     The Company has recently shifted its distribution model to the use of
Ansoft's worldwide direct sales personnel. There can be no assurance that this
transition will not result in dislocations or delays in penetration in these
markets or that the recent shift will not result in start-up costs and other
expenses. These expenses may be incurred before a commensurate level of revenues
are generated in these markets. Failure to generate a

                                       85
<PAGE>   93

requisite level of revenues in light of these expenses could have a material
adverse effect on the Company's business, operating results and financial
condition.

     SALES AND MARKETING EXPENSES.  Sales and marketing expenses consist of
salaries, commissions paid to internal sales and marketing personnel and
international distributors, promotional costs and related operating expenses.
Sales and marketing expenses decreased by 17% to $1.6 million in the year ended
December 31, 1998, as compared to $1.9 million in the previous fiscal year. The
decrease is primarily attributable to the Company's decreased product sales.
Sales and marketing expenses represented 67% and 59% of total revenue in the
years ended December 31, 1998 and 1997, respectively.

     RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
include all costs associated with the development of new products and
enhancements to existing products. Research and development expenses for the
year ended December 31, 1998 increased 36% to $562,000, as compared to $413,000
for the previous fiscal year. The increase is due to increased research and
development personnel primarily as a result of additional personnel. Research
and development expenses represented 23% and 12% of total revenue in the years
ended December 31, 1998 and 1997, respectively.

     GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
for the year ended December 31, 1998 increased 45% to $615,000, as compared to
$423,000 for the previous fiscal year. The increase is due to additional costs
required to support operations, including the hiring of additional
administrative personnel. General and administrative expenses represented 26%
and 13% of total revenue in the years ended December 31, 1998 and 1997,
respectively.

     DEPRECIATION AND AMORTIZATION EXPENSE.  Depreciation and amortization
expense for the year ended December 31, 1998 increased to $764,000, as compared
to $347,000 for the previous fiscal year. The increase is due to recording
amortization of previously capitalized software development costs.

     OTHER EXPENSE (NET).  Other expense consists primarily of interest expense
on the notes payable and loans payable to related parties. Other expense (net)
for the year ended December 31, 1998 increased to $58,000, compared to $37,000
for the previous fiscal year. Interest expense increased due to the higher notes
and loans payable balance during fiscal 1998.

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

     REVENUE.  Total revenue for the year ended December 31, 1997 increased 108%
to $3.3 million from $1.6 million in the previous fiscal year. Product revenue
during the year ended December 31, 1997 increased 116% to $2.2 million from $1.0
million during the previous fiscal year. The increase in product revenue is
primarily attributable to higher sales in the Asia-Pacific region. Maintenance
revenue increased by 45% to $613,000 for the year ended December 31, 1997, as
compared with $423,000 in the previous year. The increase in maintenance revenue
is attributable to the continued growth of the installed base of customers.

     International revenue, principally from Asia, accounted for 52% and 31% of
the Company's total product revenue in the years ended December 31, 1997 and
1996, respectively.

                                       86
<PAGE>   94

     SALES AND MARKETING EXPENSES.  Sales and marketing expenses increased by
68% to $1.9 million in the year ended December 31, 1997, as compared to $1.1
million in the previous fiscal year. The increase is primarily attributable to
the Company's increased product sales. Sales and marketing expenses represented
59% and 73% of total revenue in the years ended December 31, 1997 and 1996,
respectively.

     RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses for
the year ended December 31, 1997 increased 29% to $413,000, as compared to
$320,000 for the previous fiscal year. The increase is due to increased research
and development personnel primarily as a result of additional personnel.
Research and development expenses represented 13% and 20% of total revenue in
the years ended December 31, 1997 and 1996, respectively.

     GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
for the year ended December 31, 1997 decreased 31% to $423,000, as compared to
$610,000 for the previous fiscal year. The decrease is due to the departure of
executive administrative personnel during the year. General and administrative
expenses represented 13% and 39% of total revenue in the years ended December
31, 1997 and 1996, respectively.

     DEPRECIATION AND AMORTIZATION EXPENSE.  Depreciation and amortization
expense for the year ended December 31, 1997 increased to $347,000, as compared
to $338,000 for the previous fiscal year. The increase is due to recording
amortization of previously capitalized software development costs.

     OTHER EXPENSE (NET).  Other expense consists primarily of interest expense
on the notes payable and loans payable to related parties. Other expense (net)
for the year ended December 31, 1997 increased to $37,000, compared to $30,000
for the previous fiscal year. Interest expense increased due to the higher notes
and loans payable balance during fiscal 1997.

LIQUIDITY AND CAPITAL RESOURCES

     As of July 31, 1999, the funding requirements of the operating activities
of Pacific Numerix were provided by Ansoft.

     Ansoft believes that its available funds will be sufficient to meet its
anticipated cash needs for Pacific Numerix's working capital and capital
expenditures for at least the next twelve months. Thereafter, if cash generated
from operations is insufficient to satisfy our liquidity requirements, we may
seek additional funds through equity or debt financing. There can be no
assurance that additional financing will be available or that, if available,
such financing will be on terms favorable to us.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     None.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL
DISCLOSURE

     None. There has not been a change of accountants in the past 24 months nor
has there been any disagreement on any matter of accounting principles or
practices during the same period.

                          INDEPENDENT AUDITORS' REPORT

To The Board of Directors of
Pacific Numerix Corporation

     We have audited the accompanying balance sheets of Pacific Numerix
Corporation as of December 31, 1998 and 1997, and the related statements of
operations, changes in stockholders' equity, and cash flows for the years ended
December 31, 1998, 1997 and 1996. These financial statements are the
responsibility of the Company'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 audits 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 financial position of Pacific Numerix Corporation
as of December 31, 1998 and 1997, and the results of its operations, changes in
stockholders' equity, and its cash flows for the years ended December 31, 1998,
1997 and 1996, in conformity with generally accepted accounting principles.

     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 12 to the
financial statements, the Company sustained a substantial operating loss for the
year ended December 31, 1998. In addition, the Company used substantial amounts
of working capital in its operations and as of December 31, 1998, current
liabilities exceed current assets by $563,737. These conditions raise
substantial doubt about its ability to continue as a going concern. Management's
plans regarding those matters also are described in Note 12. The financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
           (INFORMATION AS OF JULY 31, 1999 AND FOR THE PERIOD ENDED
                      JULY 31, 1999 AND 1998 IS UNAUDITED)

NOTE 1
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, NATURE OF OPERATIONS AND USE OF
ESTIMATES:

NATURE OF BUSINESS:

     Pacific Numerix Corporation (the "Company") is a Corporation, which was
duly formed and organized under the laws of the State of California on September
27, 1984. The Company was reincorporated as a Nevada corporation in June 1995.
The Company's principal business activities include the development, sale and
distribution of computer software products for the design and manufacture of
printed circuit boards and integrated circuits primarily for manufacturing
clients, both domestic and foreign.

INTERIM FINANCIAL INFORMATION

     The interim financial statements for the seven month periods ended July 31,
1999 and 1998 are unaudited. In the opinion of management, such statements
reflect all adjustments (consisting only of normal recurring adjustments)
necessary for a fair representation of the results of the interim period. The
results of operations for the seven month period ended July 31, 1999 are not
necessarily indicative of the results of the entire year.

PERVASIVENESS 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 and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS:

     Cash and cash equivalents are considered to be all highly liquid
investments purchased with an initial maturity of three (3) months or less.

ACCOUNTS RECEIVABLE -- TRADE:

     The Company provides for potentially uncollectible accounts receivable by
use of the allowance method. The allowance is provided based upon a review of
the individual accounts outstanding, and the Company's prior history of
uncollectible accounts receivable. Management believes all receivables are fully
collectible as of December 31, 1998 and 1997. Accordingly, no provisions for
uncollectible accounts have been included in the accompanying financial
statements.

                          PACIFIC NUMERIX CORPORATION

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

PROPERTY AND EQUIPMENT:

     Property and equipment are recorded at cost. Depreciation is provided for
on the straight-line method over the estimated useful lives of the assets. The
average lives range from three to five years. Maintenance and repairs that
neither materially add to the value of the property nor appreciably prolong its
life are charged to expense as incurred. Betterments or renewals are capitalized
when incurred. Depreciation expense was $97,524, $88,927, and $72,587,
respectively, for the years ended December 31, 1998, 1997 and 1996.

     The Company is the lessee of computer equipment under three (3) capital
lease agreements expiring through May, 2001. The assets and liabilities under
the capital lease agreements are recorded at the lower of the present value of
the minimum lease payments or the fair value of the assets. The assets are being
depreciated over their estimated productive lives. Depreciation of the assets
under the capital lease agreements is included in depreciation expense as noted
above, for the years ended December 31, 1998, 1997 and 1996.

SOFTWARE DEVELOPMENT COSTS:

     The Company capitalizes software development costs in accordance with
Statement of Financial Accounting Standards No. 86, "Accounting for the Costs of
Computer Software to be Sold, Leased, or Otherwise Marketed." Capitalization of
software development costs begins upon the establishment of technological
feasibility of the product. The establishment of technological feasibility and
the ongoing assessment of the recoverability of these costs requires
considerable judgement by management with respect to certain external factors
including, but not limited to, anticipated future gross product revenue,
estimated economic life, and changes in software and hardware technology.
Amortization of capitalized software development costs begins when the products
are available for general release to customers and is computed on a
product-by-product basis using straight-line amortization with useful lives of
five years or, if less, the remaining estimated economic life of the product.
The Company evaluates the estimated net realizable value of each software
product at each balance sheet date and records writedowns to net realizable
value for any products for which expected future cash flows is less than the net
book value. It is reasonably possible that the estimates of anticipated future
gross revenues, the remaining estimated economic life of the products, or both,
could differ form those used to assess the recoverability of these costs.

     For the years ended December 31, 1998, 1997 and 1996, accumulated
amortization was $1,458,303 and $791,853, and $533,798, respectively.
Amortization expense was $666,450, $258,055 and $265,656, respectively, for the
years ended December 31, 1998, 1997 and 1996.

REVENUE RECOGNITION AND DEFERRED REVENUE:

     Product revenue consists principally of revenue earned under software
license agreements and is recognized when the software has been shipped, there
are no significant obligations remaining, and collection is probable. Service
revenue consists primarily of revenues received for performing consulting and
customer training and is recognized as the

                                       95

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

services are performed. Maintenance revenue consists of fees for providing
product updates, user documentation and technical support. Maintenance revenue
is being recognized ratably over the applicable lives of the respective
contracts, generally one year.

     The Company uses distributors for certain of its sales. Revenue generated
through distributors is generally recorded at the gross sales price paid by the
customer. Commissions withheld by distributors are recorded as sales and
marketing expense.

DEFERRED INCOME TAXES:

     Deferred income taxes are provided on an asset and liability method,
whereby deferred tax assets are recognized for deductible temporary differences
and operating loss and tax credit carry forwards and deferred tax liabilities
are recognized for taxable temporary differences. Temporary differences are the
differences between the reported amounts of assets and liabilities and their tax
basis. Deferred tax assets are reduced by a valuation allowance when, in the
opinion of management, there is uncertainty of the utilization of the operating
losses in future periods. Deferred tax assets and liabilities are adjusted for
the effects of changes in tax laws and rates on the date of enactment.

STOCK-BASED COMPENSATION:

     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and the related
interpretations in accounting for its employee stock options. Under APB 25,
because the exercise price of employee stock options equals or exceeds the
market price of the underlying stock on the date of grant, no compensation
expense is recorded. The Company has adopted the disclosure-only provisions of
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation".

years ended December 31, 1998, 1997 and 1996. Had compensation cost for
stock-based compensation been determined based on the fair value of the options

     The fair value of option grants is estimated as of the date of grant
utilizing the Black-Scholes option-pricing model with the following weighted
average assumptions for grants in 1998 and 1997, expected life of options of two
(2) years, risk-free interest rates of eight percent (8%), and a zero percent
(0%) dividend yield. The weighted average fair value at date of grant for
options granted during 1998, 1997 and 1996 approximated $.06, $.07, and $.01,
respectively.

Stockholder Options:

     The Company has granted options in connection with various stock offerings.
The options are exercisable on a one-for-one basis. Following is a summary of

EMPLOYEE BENEFIT PLANS:

     The Company has implemented a profit sharing plan covering virtually all
full-time employees. The plan is designed as a 401(k) profit sharing plan.
Employees are permitted to make voluntary contributions to the plan. In
addition, the Company can make contributions to the Plan. These contributions
are at the discretion of the Board of Directors, and are subject to certain
limitations. For the years ended December 31, 1998 and 1997, the Company made no
discretionary contributions.

NOTE 10
YEAR 2000 ISSUE: (UNAUDITED)

     Like other companies, Pacific Numerix Corporation could be adversely
affected if the computer systems we, our suppliers, or our customers use do not
properly process and calculate date-related information and data from the period
surrounding and including January 1, 2000. This is commonly known as the "Year
2000" issue. Additionally, this issue could impact non-computer systems and
devices such as production equipment, elevators, etc. At this time, because of
the complexities involved in the issue, management cannot provide assurances
that the Year 2000 issue will not have an impact on the Company's operations.

NOTE 11
SUBSEQUENT EVENTS:

     Subsequent to December 31, 1998 the Company signed a Letter of Intent with
Ansoft Corporation, in which Ansoft Corporation desires to purchase all of the
outstanding common and preferred stock of the Company in exchange for shares of
Ansoft Corporation's common stock. The Company is currently negotiating the

agreement with Ansoft Corporation and anticipates closing the transaction prior
to April 1999, subject to the due diligence procedures of the companies.

NOTE 12
GOING CONCERN:

     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. However, the Company has sustained a
substantial operating loss for the year ending December 31, 1998. In addition,
the Company used substantial amounts of working capital in its operations and as
of December 31, 1998 current liabilities exceed current assets by $563,737.

     In view of these matters, realization of a major portion of the assets in
the accompanying balance sheet is dependent upon continued operations of the
Company, which in turn is dependent upon the Company's ability to meet its
financing requirements, and the success of its future operations. Management
believes that actions being presently taken, including the potential sale of its
stock as discussed in Note 11, provide the opportunity for the Company to
continue as a going concern.

        6.6  Waivers

     Any term or provision of this Agreement may be waived, or the time for its
performance may be extended, by the party or parties entitled to the benefit
thereof, but any such waiver must be in writing and must comply with the notice
provisions contained in Section 6.2. The failure of any party to enforce at any

unenforceable in any respect, such invalidity, illegality or unenforceability
will not affect any other provisions of this Agreement, and this Agreement will
be construed as if such invalid, illegal or unenforceable provision or
provisions had never been contained herein, unless the deletion of such
provision or provisions would result in such a material change as to cause the
completion of these transactions to be unreasonable.

will be considered an original instrument and all of which together will be
considered one and the same agreement, and will become effective when

than the parties to this Agreement and their respective successors and permitted
assigns.

domestic nonprofit corporation who voted against the merger may, without prior
notice, but within 30 days after the effective date of the merger, resign from
membership and is thereby excused from all contractual obligations to the
constituent or surviving corporations which did not occur before his resignation
and is thereby entitled to those rights, if any, which would have existed if
there had been no merger and the membership had been terminated or the member
had been expelled.

member of a domestic nonprofit corporation, including, but not limited to, a
cooperative corporation, which supplies services described in chapter 704 of NRS

             (1) If approval by the stockholders is required for the merger by

        its parent under NRS 92A.180.

          (b) Consummation of a plan of exchange to which the domestic
     corporation is a party as the corporation whose subject owner's interests
     will be acquired, if he is entitled to vote on the plan.

          (c) Any corporate action taken pursuant to a vote of the stockholders
     to the event that the articles of incorporation, bylaws or a resolution of
     the board of directors provides that voting or nonvoting stockholders are
     entitled to dissent and obtain payment for their shares.

     2. A stockholder who is entitled to dissent and obtain payment under NRS
92A.300 to 92A.500, inclusive, may not challenge the corporate action creating

or the domestic corporation.

<PAGE>   128

     92A.390 LIMITATIONS ON RIGHT OF DISSENT: STOCKHOLDERS OF CERTAIN CLASSES OR
SERIES; ACTION OF STOCKHOLDERS NOT REQUIRED FOR PLAN OF MERGER.  1. There is no
right of dissent with respect to a plan of merger or exchange in favor of
stockholders of any class or series which, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting at
which the plan of merger or exchange is to be acted on, were either listed on a
national securities exchange, included in the national market system by the
National Association of Securities Dealers, Inc., or held by at least 2,000
stockholders of record, unless:

          (a) The articles of incorporation of the corporation issuing the
     shares provide otherwise; or

          (b) The holders of the class or series are required under the plan of
     merger or exchange to accept for the shares anything except:

             (1) Cash, owner's interests or owner's interests and cash in lieu
        of fractional owner's interests of:

                  (I) The surviving or acquiring entity; or

                  (II) Any other entity which, at the effective date of the plan
             of merger or exchange, were either listed on a national securities
             exchange, included in the national market system by the National
             Association of Securities Dealers, Inc., or held of record by a
             least 2,000 holders of owner's interests of record; or

             (2) A combination of cash and owner's interests of the kind
        described in sub-subparagraphs (I) and (II) of subparagraph (1) of
        paragraph (b).

     2. There is no right of dissent for any holders of stock of the surviving
domestic corporation if the plan of merger does not require action of the
stockholders of the surviving domestic corporation under NRS 92A.130.

     92A.400 LIMITATIONS ON RIGHT OF DISSENT: ASSERTION AS TO PORTIONS ONLY TO
SHARES REGISTERED TO STOCKHOLDER; ASSERTION BY BENEFICIAL STOCKHOLDER.  1. A
stockholder of record may assert dissenter's rights as to fewer than all of the
shares registered in his name only if he dissents with respect to all shares
beneficially owned by any one person and notifies the subject corporation in
writing of the name and address of each person on whose behalf he asserts
dissenter's rights. The rights of a partial dissenter under this subsection are
determined as if the shares as to which he dissents and his other shares were
registered in the names of different stockholders.

     2. A beneficial stockholder may assert dissenter's rights as to shares held
on his behalf only if:

          (a) He submits to the subject corporation the written consent of the
     stockholder of record to the dissent not later than the time the beneficial
     stockholder asserts dissenter's rights; and

          (b) He does so with respect to all shares of which he is the
     beneficial stockholder or over which he has power to direct the vote.

92A.500, inclusive, and be accompanied by a copy of those sections.

     2. If the corporate action creating dissenters' rights is taken by written
consent of the stockholders or without a vote of the stockholders, the domestic
corporation shall notify in writing all stockholders entitled to assert
dissenters' rights that the action was taken and send them the dissenter's
notice described in NRS 92A.430. (Last amended by Ch. 208, L. '97, eff.

     first announcement to the news media or to the stockholders of the terms of

     located; or

          (b) At the election of any dissenter residing or having its registered

     year ending not more than 16 months before the date of payment, a statement
     of income for that year, a statement of changes in the stockholders' equity
     for that year and the latest available interim financial statements, if

     value of the shares;

          (c) An explanation of how the interest was calculated;

                                       14
<PAGE>   131

          (e) A copy of NRS 92A.300 to 92A.500, inclusive.

     92A.470 PAYMENT FOR SHARES: SHARES ACQUIRED ON OR AFTER DATE OF DISSENTER'S
NOTICE.  1. A subject corporation may elect to withhold payment from a dissenter
unless he was the beneficial owner of the shares before the date set forth in
the dissenter's notice as the date of the first announcement to the news media
or to the stockholders of the terms of the proposed action.

     2. To the extent the subject corporation elects to withhold payment, after
taking the proposed action, it shall estimate the fair value of the shares, plus
accrued interest, and shall offer to pay this amount to each dissenter who
agrees to accept it in full satisfaction of his demand. The subject corporation
shall send with its offer a statement of its estimate of the fair value of the
shares, an explanation of how the interest was calculated, and a statement of
the dissenters' right to demand payment pursuant to NRS 92A.480.

     92A.480 DISSENTER'S ESTIMATE OF FAIR VALUE: NOTIFICATION OF SUBJECT
CORPORATION; DEMAND FOR PAYMENT OF ESTIMATE.  1. A dissenter may notify the
subject corporation in writing of his own estimate of the fair value of his
shares and the amount of interest due, and demand payment of his estimate, less
any payment pursuant to NRS 92A.460, or reject the offer pursuant to NRS 92A.470
and demand payment of the fair value of his shares and interest due, if he
believes that the amount paid pursuant to NRS 92A.460 or offered pursuant to NRS
92A.470 is less than the fair value of his shares or that the interest due is
incorrectly calculated.

     2. A dissenter waives his right to demand payment pursuant to this section
unless he notifies the subject corporation of his demand in writing within 30
days after the subject corporation made or offered payment for his shares.

     92A.490 LEGAL PROCEEDING TO DETERMINE FAIR VALUE: DUTIES OF SUBJECT
CORPORATION; POWERS OF COURT; RIGHTS OF DISSENTER. 1. If a demand for payment
remains unsettled, the subject corporation shall commence a proceeding within 60
days after receiving the demand and petition the court to determine the fair
value of the shares and accrued interest. If the subject corporation does not
commence the proceeding within the 60-day period, it shall pay each dissenter
whose demand remains unsettled the amount demanded.

     2. A subject corporation shall commence the proceeding in the district
court of the county where its registered office is located. If the subject
corporation is a foreign entity without a resident agent in the state, it shall
commence the proceeding in the county where the registered office of the
domestic corporation merged with or whose shares were acquired by the foreign
entity was located.

     3. The subject corporation shall make all dissenters, whether or not
residents of Nevada, whose demands remain unsettled, parties to the proceeding
as in an action against their shares. All parties must be served with a copy of
the petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.

     4. The jurisdiction of the court in which the proceeding is commenced under
subsection 2 is plenary and exclusive. The court may appoint one or more persons
as appraisers to receive evidence and recommend a decision on the question of
fair value. The appraisers have the powers described in the order appointing
them, or any amendment thereto. The dissenters are entitled to the same
discovery rights as parties in other civil proceedings.

                                       15
<PAGE>   132

     5. Each dissenter who is made a party to the proceeding is entitled to a
judgment:

          (a) For the amount, if any, by which the court finds the fair value of
     his shares, plus interest, exceeds the amount paid by the subject
     corporation; or

          (b) For the fair value, plus accrued interest, of his after-acquired
     shares for which the subject corporation elected to withhold payment
     pursuant to NRS 92A.470.

     92A.500 LEGAL PROCEEDING TO DETERMINE FAIR VALUE: ASSESSMENT OF COSTS AND
FEES.  1. The court in a proceeding to determine fair value shall determine all
of the costs of the proceeding, including the reasonable compensation and
expenses of any appraisers appointed by the court. The court shall assess the
costs against the subject corporation, except that the court may assess costs
against all or some dissenters, in amounts the court finds equitable, to the
extent the court finds the dissenters acted arbitrarily, vexatiously or not in
good faith in demanding payment.

     2. The court may also assess the fees and expenses of the counsel and
experts for the respective parties, in amounts the court finds equitable:

          (a) Against the subject corporation and in favor of all dissenters if
     the court finds the subject corporation did not substantially comply with
     the requirements of NRS 92A.300 to 92A.500, inclusive; or

          (b) Against either the subject corporation or a dissenter in favor of
     any other party, if the court finds that the party against whom the fees
     and expenses are assessed acted arbitrarily, vexatiously or not in good
     faith with respect to the rights provided by NRS 92A.300 to 92A.500,
     inclusive.

     3. If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the subject corporation, the
court may award to those counsel reasonable fees to be paid out of the amounts
awarded to the dissenters who were benefited.

     4. In a proceeding commenced pursuant to NRS 92A.460, the court may assess
the costs against the subject corporation, except that the court may assess
costs against all or some of the dissenters who are parties to the proceeding,
in amounts the court finds equitable, to the extent the court finds that such
parties did not act in good faith in instituting the proceeding.

     5. This section does not preclude any party in a proceeding commenced
pursuant to NRS 92A.460 or 92A.490 from applying the provisions of N.R.C.P. 68
or NRS 17.115.

ITEM 20.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

     Section 145 of the Delaware General Corporation Law allows for the
indemnification of officers, directors, and other corporate agents in terms
sufficiently broad to indemnify such persons under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising in
connection with certain lawsuits to which they may be made parties by reason of
their being directors, officers, employees or agents if they have been
successful on the merits or otherwise. Article VII of the Registrant's
Certificate of Incorporation and Article VI of the Registrant's Bylaws provide
for indemnification of the Registrant's directors, officers, employees and other
agents to the extent and under the circumstances permitted by Delaware Law. The
Registrant has also entered into agreements with its directors and officers that
will require the Registrant, among other things, to indemnify them against
certain liabilities that may arise by reason of their status or service as
directors to the fullest extent not prohibited by law.

ITEM 22.  UNDERTAKINGS

     A. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(e) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to the initial BONA FIDE offering thereof.

     B. The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities hereunder through use of a prospectus
which is a part of this registration statement, by any person or party who is
deemed to be an underwriter within the meaning of Rule 145(c), the issuer
undertakes that such reoffering prospectus will contain the information called
for by the applicable registration form with respect to reofferings by persons
who may be deemed underwriters, in addition to the information called for by the
other items of the applicable form.

     C. The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (B) immediately proceeding, or (ii) that purports to meet
the requirements of

                                      II-3
<PAGE>   136

Section 10(a)(3) of the Act and is used in connection with an offering of
securities subject to Rule 415, will be filed as a part of an amendment to the
registration statement and will not be used until such amendment is effective,
and that, for purpose of determining any liability under the Securities Act of
1933, as amended, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial BONA
FIDE offering thereof.

     D. Insofar a indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer, or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed it the Act and will be governed by the final adjudication of
such issue.

     E. The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporate (by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     F. The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all in concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.

Ansoft Corporation
Four Station Square, Suite 200
Pittsburgh, PA 15219

Dear Sirs:

     We have acted as counsel to Ansoft Corporation, a Delaware corporation
("Ansoft," the "Company" or the "Registrant"), in connection with its
Registration Statement on Form S-4 (the "Registration Statement") filed with
the Securities and Exchange Commission relating to the proposed offering of the
Company's common stock, par value $.01 per share (the "Shares"), pursuant to
the terms of the Agreement and Plan of Merger, dated as of November 19, 1999,
(the "Merger Agreement") by and among Ansoft, Ansoft Acquisition Corp., a
Nevada corporation and a wholly-owned subsidiary of Ansoft ("Merger Sub") and
Pacific Numerix Corporation ("PNC"), which provides for the merger of Merger
Sub with and into PNC, with PNC surviving the merger (the "Merger"). The Shares
are to be issued to the shareholders of PNC in accordance with the terms of the
Merger Agreement, in exchange for such shareholder's shares of PNC common and
preferred stock.

     In connection with the proposed offering, we have examined the Company's
Certificate of Incorporation and Bylaws, as presently in effect, the Company's
relevant corporate proceedings, the draft Registration Statement on Form S-4
covering the proposed offering, including the proxy statement/prospectus filed
as a part of the Registration Statement, the Merger Agreement, and such other
documents, records, certificates or public officials, statutes and decisions as
we considered necessary to express the opinions contained herein. In the
examination of such documents, we have assumed the genuineness of all
signatures and the authenticity of all documents submitted to us as originals
and the conformity to the original documents of all documents submitted to us
as certified or photostatic copies.

     Based on the foregoing, we are of the opinion that:

     1.   The Shares have been duly authorized for issuance.

     2.   The Shares when issued and delivered to the shareholders of PNC in
exchange for shares of PNC common and preferred stock in accordance with the
terms of the Merger Agreement, will be validly issued, fully paid and
nonassessable.

     Our opinion is limited to the laws of the Commonwealth of Pennsylvania,
the General Corporation Law of the State of Delaware and the United States of
America, insofar as such laws apply, and we express no opinion as to conflicts
of law rules, or the laws of any states or

jurisdictions, including federal laws regulating securities or other federal
laws, or the rules and regulations of stock exchanges or any other regulatory
body, other than as specified above.

     We assume no obligation to advise you of any changes to the foregoing
subsequent to the delivery of this opinion letter. This opinion letter has been
prepared solely for your use in connection with the filing of the Registration
Statement on the date of this opinion letter and shall not be quoted in whole
or in part or otherwise referred to, nor filed with or furnished to any
governmental agency or other person or other entity, without the prior written
consent of this firm.

     We hereby consent to the filing of this opinion letter as Exhibit 5.01 to
the Registration Statement and to any reference to us in the Prospectus which
is a part hereof.

                                   Sincerely,

                                   BUCHANAN INGERSOLL
