Item 1.01. Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On March 31, 2008, ANSYS, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Ansoft Corporation, a Delaware corporation, (“Ansoft”), Evgeni, Inc., a wholly owned subsidiary of the Company (“Merger Sub”), and Sidney LLC, a single member Delaware limited liability company and a wholly owned subsidiary of the Company (“Merger LLC”). Subject to the terms of the Merger Agreement, Merger Sub will merge with and into Ansoft, and then Ansoft, as the surviving corporation, will merge with and into Merger LLC, with Merger LLC being the ultimate surviving entity and continuing as a wholly owned subsidiary of the Company (the “Merger”). The Merger is intended to qualify as a reorganization for U.S. federal income tax purposes.

Subject to the terms of the Merger Agreement, at the effective time of the Merger, each issued and outstanding share of Ansoft common stock will be converted into the right to receive (i) cash, without interest, in an amount equal to $16.25 per share, and (ii) 0.431882 of a share of Company common stock. Shares of Company common stock issued in the transaction will be registered pursuant to a registration statement on Form S-4.

Depending on the number of Ansoft stock options which may be exercised prior to closing, the aggregate amount of cash to be paid by the Company in the Merger will equal approximately $416 million and the aggregate number of shares of Company common stock issuable in the Merger will equal approximately 11.1 million shares. Such number of shares of Company common stock does not include shares issuable as a result of the assumption of outstanding options to purchase Ansoft common stock. Pursuant to the Merger Agreement, the actual number of shares of Company common stock issuable pursuant to the assumption of Ansoft common stock options will vary depending upon the average closing price of Ansoft’s common stock for the thirty trading days ending one day prior to the closing of the Merger.

The Merger Agreement contains a provision under which Ansoft is subject to customary “no-shop” restrictions on its ability to solicit alternative acquisition proposals from third parties, provide information to third parties with respect to any such alternative acquisition proposals and engage in discussions or negotiations with third parties regarding any such alternative acquisition proposals. The “no-shop” provision is subject to a customary “fiduciary-out” provision, which, under certain circumstances, would enable Ansoft to provide information to, and engage in discussions or negotiations with, third parties with respect to alternative acquisition proposals.

The Merger Agreement contains certain termination rights for both the Company and Ansoft. Upon termination under specified circumstances set forth in the Merger Agreement, Ansoft would be required to pay the Company a termination fee of $27,034,000.

Following the closing of the Merger, Dr. Zoltan J. Cendes, the Chairman and Chief Technology Officer of Ansoft, is expected to join the Company’s board of directors.

The Company has obtained financing commitments, the proceeds of which will be used to provide funds to consummate the transactions contemplated by the Merger Agreement. The consummation of the Merger is not subject to any financing condition.

The completion of the Merger is subject to various customary closing conditions, including, among other things, obtaining the approval of Ansoft’s stockholders, customary regulatory approvals and expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto, and is incorporated into this report by reference.

Voting Agreements

In connection with the Merger Agreement, the Company has entered into voting agreements (the “Voting Agreements”), dated as of March 31, 2008, with each of Nicholas Csendes and Dr. Zoltan J. Cendes (each a “Stockholder,” and collectively, the “Stockholders”) pursuant to which, among other things, each Stockholder has agreed to vote all shares of Ansoft common stock beneficially owned by such Stockholder (the “Covered Shares” ) in favor of the approval of the Merger Agreement and the transactions contemplated thereby and against any acquisition proposal made in opposition to, or in competition with, the consummation of the Merger and the transactions contemplated by the Merger Agreement.

In addition, pursuant to the terms of the Voting Agreements, each Stockholder granted the Company an irrevocable proxy to vote the Covered Shares solely with respect to the matters set forth in the Voting Agreement and only to the extent that such Stockholder is unable to vote the Covered Shares pursuant to such Stockholder’s obligations under his respective Voting Agreement. The Stockholders own beneficially and of record an aggregate of approximately 16% of Ansoft’s outstanding common stock.

The foregoing description of the Voting Agreements does not purport to be complete and is qualified in its entirety by reference to the Voting Agreements, a copy of a form of which is attached hereto as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

WHEREAS, Buyer, Merger Sub, Merger LLC and Seller intend to effect a merger (the “Merger”) of Merger Sub with and into Seller in accordance with this Agreement and the General Corporation Law of the State of Delaware (the “DGCL”), with Seller to be the surviving corporation of the Merger, which Merger will be followed immediately by a merger of the Surviving Corporation (as defined below) with and into Merger LLC (the “Upstream Merger”), with the Merger LLC to be the surviving entity in the Upstream Merger (the “Surviving Entity”). It is intended that the Merger be mutually interdependent with and a condition precedent to the Upstream Merger and that the Upstream Merger shall, through the binding commitment evidenced by this Agreement, be effected immediately following the Effective Time (as defined below) without further approval, authorization or direction from or by any of the parties hereto.

WHEREAS, the respective Boards of Directors of Buyer, Merger Sub, Seller and the managing member of Merger LLC have declared that it is advisable and in the best respective interests of Buyer, Merger Sub, Merger LLC and Seller and their respective stockholders or sole member, as applicable, to consummate, and have approved this Agreement and the transactions provided for herein, pursuant to which, subject to the terms and conditions set forth herein, the Merger and the Upstream Merger shall occur.

WHEREAS, concurrently with the execution of this Agreement, and as an inducement to Buyer, Merger Sub and Merger LLC to enter into this Agreement, Buyer and certain stockholders have entered into voting agreements, dated as of the date hereof, in the form attached hereto as Exhibit A (each a “Voting Agreement” and collectively, the “Voting Agreements”), pursuant to which such stockholders have agreed, subject to the terms thereof, to vote or cause to be voted, at Seller’s Stockholder Meeting (as defined below) all of the shares of the Seller Common Stock (as defined below) beneficially owned by such stockholder in favor of the adoption and approval of this Agreement.

WHEREAS, it is intended that the Merger and the Upstream Merger, considered together as a single integrated transaction, will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”).

WHEREAS, the parties desire to make certain representations, warranties, and agreements in connection with the Merger and to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants, representations, warranties, and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE I - THE MERGER

1.1 The Merger. Upon the terms and subject to the satisfaction or waiver of the conditions set forth in this Agreement, and in accordance with the DGCL, at the Effective Time, Merger Sub shall merge with and into Seller. Seller shall continue as the surviving corporation (the “Surviving Corporation”) in the Merger and shall continue its corporate existence under the laws of the State of Delaware. Upon consummation of the Merger, the separate corporate existence of Merger Sub shall terminate.

1.2 Effective Time. The Merger shall become effective as set forth in the certificate of merger (the “Certificate of Merger”), executed in accordance with the relevant provisions of the DGCL, which shall be filed with the Secretary of State of the State of Delaware on or before the Closing Date. The term “Effective Time” shall be the date and time when the Merger becomes effective as set forth in the Certificate of Merger. Immediately after the Effective Time, the Surviving Corporation shall cause the Upstream Merger to become effective by filing a certificate of merger with the Secretary of State of Delaware (the “Upstream Merger Certificate”), in accordance with the relevant provisions of the DGCL and the LLC Act. The “Upstream Merger Effective Time” shall be the date and time when the Upstream Merger becomes effective as set forth in the Upstream Merger Certificate.

1.3 Closing. Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) will take place at the offices of Goodwin Procter LLP, Exchange Place, Boston, Massachusetts, unless another place is agreed to in writing by the parties hereto, at 10:00 a.m., local time, on a date (the “Closing Date”) specified by the parties, which shall be no later than two (2) Business Days after the satisfaction or waiver (subject to applicable Law) of the latest to occur of the conditions set forth in Article VII (other than those conditions that relate to action to be taken at the Closing, but subject to satisfaction of such conditions at the Closing), unless this Agreement has been theretofore terminated pursuant to its terms or unless extended by mutual agreement of the parties.

1.4 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in this Agreement and in the appropriate provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, the Surviving Corporation shall possess all the rights, privileges, powers and franchises, and be subject to all of the restrictions, disabilities, and duties of Seller and Merger Sub, as provided under Section 259 of the DGCL. At and after the Upstream Merger Effective Time, the Upstream Merger shall have the effects set forth in this Agreement and in the appropriate provisions of the DGCL and the LLC Act. Without limiting the generality of the foregoing, and subject thereto, at the Upstream Merger Effective Time, the Surviving Entity shall possess all the rights, privileges, powers and franchises, and be subject to all of the restrictions, disabilities, and duties of the Surviving Corporation and Merger LLC, as provided in the DGCL and the LLC Act and all of the rights and obligations of the Surviving Corporation under this Agreement shall be deemed the rights and obligations of the Surviving Entity.

From and after the Effective Time, the Bylaws of Seller (the “Seller Bylaws”), as in effect immediately prior to the Effective Time, shall be amended and restated to be identical to the Bylaws of Merger Sub as in effect immediately prior to the Effective Time (which shall contain such provisions as are necessary to give full effect to the exculpation and indemnification provided for in Section 6.7 hereof), and as so amended shall be the Bylaws of the Surviving Corporation, until thereafter amended as provided therein and in accordance with applicable Law (the “Surviving Corporation Bylaws”).

(b) At the Upstream Merger Effective Time, by virtue of the Upstream Merger and without any action on the part of Merger LLC or the Surviving Corporation, the Certificate of Formation of Merger LLC, as in effect immediately prior to the Upstream Merger Effective Time, shall be the Certificate of Formation of the Surviving Entity until thereafter amended in accordance with the LLC Act, except the name of the Surviving Entity shall be Sidney LLC (the “Surviving Entity Certificate of Formation”).

ARTICLE II - EFFECT OF THE MERGER ON THE SELLER CAPITAL STOCK;

EXCHANGE OF SHARES

2.1 Conversion of Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of any party hereto or of the holder of any shares of the capital stock of Seller or capital stock of Merger Sub:

(a) Capital Stock of Merger Sub. Each share of the common stock of Merger Sub, par value $0.01 per share (the “Merger Sub Common Stock”), issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid, and nonassessable share of common stock, $0.01 par value per share, of the Surviving Corporation.

(b) Cancellation of Certain Stock. All shares of common stock, $0.01 par value per share, of Seller (“Seller Common Stock”) that are owned by Seller or any wholly owned Subsidiary of Seller and any shares of Seller Common Stock owned by Buyer, Merger Sub, or any other wholly owned Subsidiary of Buyer immediately prior to the Effective Time shall be cancelled and shall cease to exist and no consideration shall be delivered in exchange therefor.

(c) Conversion of Seller Common Stock. Subject to Section 2.2, each share of Seller Common Stock (other than shares to be cancelled in accordance with Section 2.1(b) and Dissenting Shares) issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, subject to adjustment as provided for in Section 8.1(c): (i) $16.25 per share in cash without interest (the “Cash Consideration”), and (ii) 0.431882 shares (the “Exchange Ratio”) of common stock, $0.01 par value per share, of Buyer (the “Buyer Common Stock”) (the “Stock Consideration”). The Cash Consideration and the Stock Consideration are sometimes referred to herein as the “Merger Consideration.” As of the Effective Time, all such shares of Seller Common Stock, when converted as provided in this Section 2.1(c), shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate (each a “Certificate” and collectively, the “Certificates”) or a book-entry share (each a “Book-Entry Share” and collectively, the “Book-Entry Shares”) representing any such shares of Seller Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration and any cash in lieu of fractional shares of Buyer Common Stock as provided under this Article II upon surrender of such Certificate or Book-Entry Share, as the case may be, in accordance with Section 2.2, without interest or dividends.

(d) Seller Stock Options and Related Matters.

(i) As soon as practicable following the date of this Agreement, the Board of Directors of Seller (or, if appropriate, any committee administering the Seller Stock Option Plans) shall adopt such resolutions or use its reasonable best effort to take such other actions as are required to provide for the conversion of each Seller Stock Option as provided in this Section 2.1(d).

4

(ii) At the Effective Time, each Seller Stock Option that is outstanding and unexercised immediately prior to the Effective Time (“Assumed Options”), whether or not vested, shall be converted into and become an option to purchase Buyer Common Stock as provided below in this Section 2.1(d)(ii), and Buyer shall assume such Seller Stock Option in accordance with this Section 2.1(d)(ii) and the terms (as in effect as of the date of this Agreement) of the Seller Stock Option Plans and/or the seller option agreement by which such Option is evidenced. All rights to purchase Seller Common Stock under Assumed Options shall, effective as of the Effective Time, thereupon be converted into rights to purchase Buyer Common Stock. Accordingly, from and after the Effective Time: (A) each Assumed Option may be exercised solely for Buyer Common Stock; (B) the number of shares of Buyer Common Stock subject to each Assumed Option shall be determined by multiplying the number of shares of Seller Common Stock that were subject to such Assumed Option immediately prior to the Effective Time by the Option Exchange Ratio, and rounding the resulting number down to the nearest whole number of Buyer Common Stock; (C) the per share exercise price for the Buyer Common Stock issuable upon exercise of each Assumed Option shall be determined by dividing the per share exercise price of Seller Common Stock subject to such Assumed Option, as in effect immediately prior to the Effective Time, by the Option Exchange Ratio, and rounding the resulting exercise price up to the nearest whole cent; and (D) after giving effect to any acceleration of vesting of any Assumed Option that will occur as a result of the Merger pursuant to the terms of any such Assumed Option, any remaining restriction on the exercise of any Assumed Option shall continue in full force and effect and the term, exercisability, remaining vesting schedule and other provisions of such Assumed Option shall otherwise remain unchanged as a result of the conversion of such Assumed Option. Buyer shall file with the SEC, no later than three (3) Business Days after the Closing, a registration statement on Form S-8 (or any successor form), if available for use by Seller, relating to the Buyer Shares issuable with respect to the Assumed Options. “Option Exchange Ratio” is the quotient of (x) $16.25, plus (A) the Exchange Ratio multiplied by (B) the average of the closing prices of Buyer Common Stock for the thirty (30) trading days ending one (1) day prior to the Closing, divided by (y) the average of the closing prices of Buyer Common Stock for the thirty (30) trading days ending one (1) day prior to the Closing, rounded to the nearest one-hundred thousandth of a cent, with $.000005 rounded down.

(iii) Notwithstanding the foregoing, in the event that the number of shares of Buyer Common Stock issuable upon the exercise of Assumed Options plus the number of shares of Buyer Common Stock to be issued in respect of shares of Seller Common Stock in the Merger (the “Total Shares”) exceeds twenty percent (20%) of the number of shares of Buyer Common Stock outstanding prior to the Merger, the number of Assumed Options shall be reduced to an amount such that the Total Shares is less than 20% of the number of shares

5

of Buyer Common Stock outstanding prior to the Merger. Any Options that are not Assumed Options by operation of this subparagraph shall be entitled to receive, in lieu of being assumed by Buyer, an amount of cash equal to $32.50, minus the exercise price of such Option not assumed. Only Options that are vested and permitted to receive such cash payment pursuant to the applicable Seller Stock Option Plan shall be eligible to receive such cash payment. The Options to receive such cash payment shall be allocated amongst the holders thereof pro rata based on the number of Options eligible to receive the cash payment held by each.

2.2 Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of Buyer Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger. In lieu thereof, Buyer shall pay to each holder of a fractional share of Buyer Common Stock an amount of cash (without interest) determined by multiplying the fractional share interest to which such holder would otherwise be entitled by the average of the last sale prices of Buyer Common Stock, as reported on Nasdaq, for the five (5) trading days immediately preceding the Closing Date, rounded to the nearest whole cent.

2.3 Exchange Procedures.

(a) Exchange Fund. At or before the Effective Time, for the benefit of the holders of Seller Common Stock, (i) Buyer shall cause to be delivered to the Exchange Agent, for exchange in accordance with this Article II, certificates representing the shares of Buyer Common Stock issuable pursuant to this Article II (“New Certificates”), and (ii) Buyer shall deliver, or shall cause to be delivered, to the Exchange Agent an aggregate amount of cash sufficient to pay the aggregate amount of cash payable pursuant to this Article II (including the estimated amount of cash to be paid in lieu of fractional shares of Buyer Common Stock) (such cash and New Certificates, being hereinafter referred to as the “Exchange Fund”). In the event the Exchange Fund shall be insufficient to make all such payments, Buyer shall promptly deliver, or cause to be delivered, additional funds with the Exchange Agent in an amount that is equal to the deficiency in the amount of funds required to make such payments. The Exchange Agent shall make payments of the aggregate Merger Consideration out of the Exchange Fund in accordance with this Agreement. The Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. As promptly as practicable following the Effective Time, and provided that Seller has delivered, or caused to be delivered, to the Exchange Agent all information which is necessary for the Exchange Agent to perform its obligations as specified herein, the Exchange Agent shall mail to each holder of record of a Certificate or Certificates or Book-Entry Share or Book-Entry Shares, as the case may be, who has not previously surrendered such Certificate or Certificates or Book-Entry Share or Book-Entry Shares, as the case may be, a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares, as the case may be, shall pass, only upon delivery of the Certificates or the Book-Entry Shares, as the case may be, to the Exchange Agent) and instructions for use in effecting the surrender of the Certificates or Book-Entry Shares, as the case may be, in exchange for the Merger Consideration into which the shares of Seller Common Stock represented by such Certificate or Certificates or Book-Entry Shares, as the case may be, shall have been converted pursuant to Sections 2.1 and 2.2 of this Agreement.

6

Upon proper surrender of a Certificate or Book-Entry Share, as applicable, for exchange and cancellation to the Exchange Agent, together with a properly completed letter of transmittal, duly executed, the holder of such Certificate or Book-Entry Share, as applicable, shall be entitled to receive in exchange therefor, as applicable, (i) a New Certificate representing that number of shares of Buyer Common Stock (if any) to which such former holder of Seller Common Stock shall have become entitled pursuant to this Agreement, (ii) a check representing that amount of cash (if any) to which such former holder of Seller Common Stock shall have become entitled pursuant to this Agreement, and/or (iii) a check representing the amount of cash (if any) payable in lieu of a fractional share of Buyer Common Stock to which such former holder has the right to receive in respect of the Certificate or Book-Entry Share, as the case may be, surrendered pursuant to this Agreement, and the Certificate or Book-Entry Share, as the case may be, so surrendered shall forthwith be cancelled. Until surrendered as contemplated by this Section 2.3(b), each Certificate and Book-Entry Share (other than Certificates or Book-Entry Shares, as applicable, representing shares to be cancelled in accordance with Section 2.1(b) and any Dissenting Shares) shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration provided in Sections 2.1 and 2.2, and any unpaid dividends and distributions thereon as provided in paragraph (c) of this Section 2.3. No interest shall be paid or accrued on any cash constituting Merger Consideration (including any cash in lieu of fractional shares) or any such unpaid dividends and distributions payable to holders of Certificates or Book-Entry Shares, as the case may be.

(c) Dividends or Other Distributions. No dividends or other distributions with a record date after the Effective Time with respect to Buyer Common Stock shall be paid to the holder of any unsurrendered Certificate or Book-Entry Share, as applicable, until the holder thereof shall surrender such Certificate or Book-Entry Share, as applicable, in accordance with this Section 2.3. After the surrender of a Certificate or Book-Entry Share, as applicable, in accordance with this Section 2.3, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to shares of Buyer Common Stock represented by such Certificate or Book-Entry Share, as applicable.

(d) Lost Certificates. The Exchange Agent and Buyer, as the case may be, shall not be obligated to deliver cash and/or a New Certificate or New Certificates representing shares of Buyer Common Stock to which a holder of Seller Common Stock would otherwise be entitled as a result of the Merger until such holder surrenders the Certificate or Certificates or Book-Entry Share or Book-Entry Shares, as the case may be, representing the shares of Seller Common Stock for exchange as provided in this Section 2.3, or, an appropriate affidavit of loss and indemnity agreement and/or a bond in an amount as may be required in each case by Buyer. If any New Certificates evidencing shares of Buyer Common Stock are to be issued in a name other than that in which the Certificate or Book-Entry Share, as the case may be, evidencing Seller Common Stock surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the Certificate or Book-Entry Share, as applicable, so surrendered shall be properly endorsed or accompanied by an executed form of assignment separate from the Certificate or Book-Entry Share, as applicable, and otherwise in proper form for transfer, and that the Person requesting such exchange pay to the Exchange Agent any transfer or other tax required by reason of the issuance of a New Certificate for shares of Buyer Common Stock in any name other than that of the registered holder of the Certificate or Book-Entry Share, as applicable, surrendered or otherwise establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

7

(e) No Further Ownership Rights in Seller Common Stock. The Merger Consideration (including any payments paid pursuant to Section 2.2) delivered upon the surrender for exchange of Certificates (or affidavit of loss in lieu thereof) or Book-Entry Shares, as applicable, in accordance with the terms hereof shall be deemed to have been delivered (and paid) in full satisfaction of all rights pertaining to such shares of Seller Common Stock, and from and after the Effective Time the stock transfer books of Seller shall be closed and thereafter there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Seller Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book-Entry Shares, as the case may be, are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled against delivery of the Merger Consideration for each share of Seller Common Stock formerly represented by such certificate.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Certificates or Book-Entry Shares, as the case may be, nine (9) months after the Effective Time (as well as any interest or proceeds from any investment thereof) shall be delivered by the Exchange Agent to Buyer, upon demand, and any holder of a Certificate or a Book-Entry Share, as the case may be, who has not previously complied with this Article II prior to the end of such nine (9) month period shall thereafter look only to Buyer for payment of its claim for the Merger Consideration. If outstanding Certificates or Book-Entry Shares, as the case may be, are not surrendered or the payment for them is not claimed prior to the date on which such shares of Buyer Common Stock or cash would otherwise escheat to or become the property of any governmental unit or agency, the unclaimed items shall, to the extent permitted by abandoned property and any other applicable Law, become the property of Buyer (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any Person previously entitled to such property. Neither the Exchange Agent nor any party to this Agreement shall be liable to any holder of shares of Seller Common Stock represented by any Certificate or Book-Entry Shares, as the case may be, for any consideration paid to a public official pursuant to applicable abandoned property, escheat, or similar laws. Buyer and the Exchange Agent shall be entitled to rely upon the stock transfer books of Seller to establish the identity of those Persons entitled to receive the Merger Consideration specified in this Agreement, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of any shares of Seller Common Stock represented by any Certificate or Book-Entry Shares, as the case may be, Buyer and the Exchange Agent shall be entitled to deposit any Merger Consideration represented thereby in escrow with an independent third party and thereafter be relieved with respect to any claims thereto.

(g) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by the Surviving Corporation; provided, however, that such investments shall be in obligations of or guaranteed by the United States of America or any agency or instrumentality thereof and backed by the full faith and credit of the United States of America or in certificates of deposit, bank repurchase agreements, or banker’s acceptances of commercial banks with capital exceeding $1 billion (based on the most recent financial statements of such bank that are then publicly available). Any net profit resulting from, or interest or income produced by, such investments shall be placed in the Exchange Fund and be payable to the Surviving Corporation.

8

(h) Withholding Rights. Each of Buyer, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of a Certificate, a Book-Entry Share or Seller Stock Option, as the case may be, such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, or any other applicable provision of law. To the extent that amounts are so withheld and paid over to the appropriate Governmental Authority by Buyer, the Surviving Corporation, or the Exchange Agent, as the case may be, such deducted, withheld and paid over amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Certificate, Book-Entry Share or Seller Stock Option, as applicable, in respect of which such deduction and withholding was made by Buyer, the Surviving Corporation, or the Exchange Agent, as the case may be.

(i) Adjustments to Prevent Dilution. In the event Buyer or Seller changes (or establishes a record date for changing) the number of, or provides for the exchange of, shares of Buyer Common Stock or Seller Common Stock issued and outstanding prior to the Effective Time as a result of a stock split, stock dividend, recapitalization, reclassification, or similar transaction with respect to the outstanding Buyer Common Stock or Seller Common Stock and the record date therefor shall be prior to the Effective Time, the Exchange Ratio and/or the Cash Consideration shall be proportionately and appropriately adjusted; provided that, for the avoidance of doubt, no such adjustment shall be made with regard to the Buyer Common Stock if (i) Buyer issues additional shares of Buyer Common Stock and receives consideration for such shares in a bona fide third party transaction, or (ii) Buyer issues employee or director stock grants or similar equity awards.

2.4 Appraisal Rights.

(a) Notwithstanding anything in this Agreement to the contrary, any shares (the “Dissenting Shares”) of the Seller Common Stock that are issued and outstanding immediately prior to the Effective Time and that are held by Seller Stockholders who, in accordance with Section 262 of the DGCL (the “Appraisal Rights Provisions”), (i) have not voted in favor of adopting this Agreement, (ii) shall have demanded properly in writing appraisal for such shares, (iii) have otherwise complied in all respects with the Appraisal Rights Provisions, and (iv) have not effectively withdrawn, lost, or failed to perfect their rights to appraisal (the “Dissenting Stockholders”), will not be converted into Merger Consideration, but at the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, shall be cancelled and shall cease to exist and shall represent the right to receive only those rights provided under the Appraisal Rights Provisions; provided, however, that all shares of Seller Common Stock held by Seller Stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to appraisal of such shares of Seller Common Stock under the Appraisal Rights Provisions shall thereupon be deemed to have been cancelled and to have been converted, as of the Effective Time, into the right to receive, without any interest thereon, the Merger Consideration.

9

(b) Seller shall give Buyer, Merger Sub and Merger LLC prompt notice of any demands received by Seller for the exercise of appraisal rights with respect to shares of Seller Common Stock and Buyer shall have the right to participate in all negotiations and proceedings with respect to such demands. Seller shall not, except with the prior written consent of Buyer, which consent shall not be unreasonably withheld, make any payment with respect to, or settle or offer to settle, any such demands.

(a) Seller has filed or furnished, as applicable, on a timely basis all forms, statements, certifications, reports and documents required to be filed or furnished by it with the SEC under the Exchange Act or the Securities Act since May 1, 2004 (the forms, statements, reports and documents filed or furnished since May 1, 2004 and those filed or furnished subsequent to the date hereof, including any amendments thereto, the “Seller SEC Reports”), except where the failure to so file or furnish would not, individually or in the aggregate, reasonably be expected to have a Seller Material Adverse Effect. Each of the Seller SEC Reports, at the time of its filing or being furnished complied in all material respects with the applicable requirements of the Securities Act, the Exchange Act and the Sarbanes-Oxley Act, and any rules and regulations promulgated thereunder applicable to the Seller SEC Reports, or, if not yet filed or furnished, will to Seller’s knowledge comply in all material respects with the applicable requirements of the Securities Act, the Exchange Act and the Sarbanes-Oxley Act, and any rules and regulations promulgated thereunder applicable to the Seller SEC Reports. As of their respective dates (or, if amended prior to the date hereof, as of the date of such amendment), the Seller SEC Reports did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading, and any Seller SEC Reports filed or furnished with the SEC subsequent to the date hereof will not to Seller’s knowledge, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading.

(b) Seller has made available to Buyer, Merger Sub and Merger LLC true, correct, and complete copies of all amendments and modifications that have not been filed by Seller with the SEC to all agreements, documents, and other instruments that previously had been filed by Seller with the SEC and are currently in effect.

(e) Seller has designed and maintains a system of internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) sufficient to provide reasonable assurance regarding the reliability of financial reporting, and, to the knowledge of Seller, such system is effective in providing such assurance. Seller (i) maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) designed to ensure that material information required to be disclosed by Seller in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to Seller’s management as appropriate to allow timely decisions regarding required disclosure and, to the knowledge of Seller, such controls and procedures are effective in ensuring such disclosures and communications, and (ii) has disclosed, based on the most recent evaluation of its chief executive officer and its chief financial officer prior to the date hereof, to Seller’s auditors and the Audit Committee of the Board of Directors of Seller (and made

Except as set forth in the disclosure schedules delivered concurrently with the execution of this Agreement to Seller (the “Buyer Disclosure Schedule”), which shall identify any exceptions to the representations, warranties and covenants contained in this Agreement (with specific reference to the particular Section or subsection to which such information relates; provided that an item disclosed in any Section or subsection shall be deemed to have been disclosed for each other Section or subsection of this Agreement to the extent the relevance is reasonably apparent on the face of such disclosure), Buyer, Merger Sub and Merger LLC hereby jointly and severally represent and warrant to Seller as follows:

4.1 Corporate Organization.

(a) Buyer is a corporation duly organized, validly existing, and in good corporate standing under the laws of the State of Delaware.

Buyer is duly licensed or qualified to do business and is in corporate good standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned, leased, or operated by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified and in corporate good standing would not, either individually or in the aggregate, reasonably be expected to have a Buyer Material Adverse Effect. The Certificate of Incorporation and Bylaws of Buyer and Merger Sub and the Certificate of Formation of Merger LLC, copies of which have previously been made available to Seller, are true, correct, and complete copies of such documents as currently in effect.

(c) Each of Merger Sub and Merger LLC was formed solely for the purpose of engaging in the transactions contemplated by this Agreement. All of the issued and outstanding capital stock of Merger Sub, which consists of 100 shares of Merger Sub Common Stock, is validly issued, fully paid, and non-assessable and is owned, beneficially and of record, by Buyer, free and clear of any claim, lien, Encumbrance, or agreement with respect thereto. Except for obligations and liabilities incurred in connection with its incorporation and the transactions contemplated by this Agreement, Merger Sub has not, and will not have, incurred, directly or indirectly, any obligations or liabilities or engaged in any business activities of any type or kind whatsoever or entered into any agreements or arrangements with any Person.

At the close of business on

The outstanding shares of Buyer’s capital stock are duly authorized, validly issued, fully paid and nonassessable, and subject to no preemptive rights or similar rights (and were not issued in violation of any preemptive or similar rights). Except for the Buyer Stock Option Plans or as reflected in Section 4.2(a) of the Buyer Disclosure Schedule, Buyer does not have and is not bound by any outstanding subscriptions, options, warrants, calls, commitments, rights agreements, or agreements of any character calling for Buyer to issue, deliver, or sell, or cause to be issued, delivered, or sold any shares of Buyer Common Stock or Buyer Preferred Stock or any other equity security of Buyer or any Subsidiary of Buyer or any securities convertible into, exchangeable for, or representing the right to subscribe for, purchase, or otherwise receive any shares of Buyer Common Stock or Buyer Preferred Stock or any other equity security of Buyer or any Subsidiary of Buyer or obligating Buyer or any such Subsidiary to grant, extend, or enter into any such subscriptions, options, warrants, calls, commitments, rights agreements, or any other similar agreements.

(e) Notwithstanding anything to the contrary set forth in this Agreement, prior to the receipt of the Seller Stockholders’ Approval, the Board of Directors of Seller may, in response to a Superior Proposal that did not result from a breach by Seller of this Section 6.4, effect a Change of Recommendation or approve or recommend any Acquisition Proposal if the Board of Directors of Seller determines in good faith, after consultation with its outside legal counsel, that failure to do so would be inconsistent with its fiduciary obligations under applicable Law, but only on or after the fifth (5^th) Business Day following Buyer’s receipt of written notice advising Buyer that the Board of Directors of Seller desires to effect a Change of Recommendation due to the existence of a Superior Proposal, specifying the material terms and conditions of such Superior Proposal (including any material changes) and identifying the Person making such Superior Proposal. Such five (5) Business Day period shall be required for each and every Superior Proposal or material modification thereto, as applicable.

(f) Nothing contained in this Section 6.4 shall be deemed to prohibit Seller or its Board of Directors from complying with its disclosure obligations under U.S. federal or state Law with regard to an Acquisition Proposal; provided, however, that if such disclosure has the substantive effect of withdrawing or adversely modifying the Seller Recommendation in any respect, such disclosure shall be deemed to be a Change of Recommendation and Buyer shall have the right to terminate this Agreement as set forth in Section 8.1(c).

(g) Seller agrees that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any Acquisition Proposal. Seller agrees that it will take the necessary steps to promptly inform the individuals or entities referred to in the first sentence hereof of the obligations undertaken in this Section 6.4 and in the Confidentiality Agreement.

6.5 Access to Information.

(a) Upon reasonable prior notice and subject to applicable Laws relating to the premerger exchange of information, Seller, shall, and shall cause each of its Subsidiaries to, afford to the officers, employees, accountants, counsel, and other Representatives of Buyer, reasonable access without undue interruption, during normal business hours during the period from the date of this Agreement until the Effective Time or the date, if any, on which this Agreement is terminated pursuant to Section 8.1, to all of its properties, books, contracts, commitments, and records (other than confidential information contained in personnel files to the extent the disclosure of such information is prohibited by privacy laws). Upon reasonable prior notice and subject to applicable Laws relating to the premerger exchange of information and the last sentence of this Section 6.5(a), Seller also shall provide Buyer during normal business hours with reasonable access to Seller’s executive officers, customers, suppliers or key Seller Employees. Neither Seller nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would contravene any Law or binding

49

agreement entered into prior to the date of this Agreement, would reasonably be expected to violate or result in a loss or impairment of any attorney-client or work product privilege or would violate or prejudice the rights of third parties. The parties hereto will use commercially reasonable efforts to make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. Notwithstanding the foregoing, Buyer shall not, without the consent of Seller (which consent shall not be unreasonably withheld or delayed), contact any customers, suppliers or key Seller Employees.

(b) With respect to all information furnished by one party to the other party or its Representatives under this Agreement, the parties shall comply with, and shall cause their respective Representatives to comply with, all of their respective obligations under the Confidentiality Agreement. Notwithstanding anything to the contrary contained in this Section 6.5, Seller shall not be obligated, and shall not be obligated to cause any of its Subsidiaries, to afford to Buyer or its Representatives any access to any of its properties, books, contracts, commitments, and records relating to, or in respect of, competitively sensitive information, the sharing of which would violate applicable Laws relating to the premerger exchange of information.

6.6 Employment and Benefit Matters.

(a) Benefits. During the period commencing on the date of this Agreement and ending at the Effective Time, Buyer agrees to consult with Seller in good faith with respect to employee transition matters, including the compensation and employee benefits to be provided to Seller Employees (defined below) after the Effective Time. Following the Effective Time, the employees of the Surviving Corporation and its Subsidiaries who remain employed after the Effective Time (the “Seller Employees”) will be entitled to participate in either (i) the Employee Programs (other than equity-based plans) on the same terms, or terms which in the aggregate provide substantially comparable benefits, as those in effect immediately prior to the Effective Time, (ii) the employee benefit plans of Buyer and its Subsidiaries on the same terms as similarly-situated employees of Buyer and its Subsidiaries or (iii) a combination of (i) and (ii), and in each case in the discretion of Buyer, and Buyer may terminate any of the Employee Programs or merge any of the Employee Programs with Buyer’s employee benefit plans as Buyer deems appropriate. Subject to the requirements of applicable Law and unless such recognition of service would result in a duplication of benefits, Buyer shall, and shall cause the Surviving Corporation to, treat, and cause the applicable benefit plans to treat, the service of Seller Employees with Seller or its Subsidiaries attributable to any period before the Effective Time as service rendered to Buyer or the Surviving Corporation for all purposes, including, but not limited to, eligibility to participate, vesting, including, but not limited to, applicability of any minimum waiting periods for participation, excluding for these purposes benefit accrual under any defined benefit plan. Without limiting the foregoing, Buyer shall not, and shall cause the Surviving Corporation not to, treat any Seller Employee as a “new” employee for purposes of any exclusions under any health or similar plan of Buyer or the Surviving Corporation for a pre-existing medical condition, except to the extent such exclusions were applicable under an Employee Program of Seller or any of its Subsidiaries immediately prior to the Effective Time.

(b) “At Will” Employment. Except with respect to employees who have entered into employment agreements with Seller or its Subsidiaries, and subject to Section 6.6(c)

50

hereof, the Seller Employees who remain employed after the Effective Time shall be considered to be employed by Buyer “at will” and nothing in this Agreement shall be construed to limit the ability of Buyer or the Surviving Corporation to terminate the employment of any such Seller Employee at any time.

(c) Continuation of Employment. No provision of this Section 6.6 shall create any third-party beneficiary rights in any employee or former employee (including any beneficiary or dependent thereof) of Seller or any Subsidiary of Seller in respect of continued employment (or resumed employment) with Buyer, the Surviving Corporation or any of Buyer’s Subsidiaries and no provision of this Section 6.6 shall create such rights in any such persons in respect of any benefits that may be provided, directly or indirectly, under any employee program or any plan or arrangement that may be established by Buyer or any of its Subsidiaries. No provision of this Agreement shall constitute a limitation on the rights to amend, modify or terminate after the Effective Time any such plans or arrangements of Buyer or any of its Subsidiaries.

6.7 Directors’ and Officers’ Indemnification and Insurance.

(a) Buyer, Merger Sub and Merger LLC agree that all rights to indemnification or exculpation now existing in favor of, and all limitations on the personal liability of each present and former director, officer, employee, fiduciary, or agent of Seller and its Subsidiaries provided for in the respective organizational documents in effect as of the date hereof, shall continue be honored and in full force and effect for a period of six (6) years after the Effective Time; provided, however, that all rights to indemnification in respect of any claims asserted or made within such period shall continue until the disposition of such claim. The Surviving Entity Limited Liability Company Agreement will contain provisions with respect to indemnification, exculpation from liability and advancement of expenses that are at least as favorable as those currently in the Seller Charter and Seller Bylaws and during such six (6) year period following the Effective Time, Buyer shall not and shall cause the Surviving Entity not to amend, repeal or otherwise modify such provisions in any manner that would materially and adversely affect the rights thereunder of individuals who at any time prior to the Effective Time was a director, officer, employee, fiduciary, or agent of Seller and its Subsidiaries in respect of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the transactions contemplated by this Agreement), unless such modification is required by Law. From and after the Effective Time, Buyer and the Surviving Corporation also agree to indemnify and hold harmless the present and former officers and directors of Seller and its Subsidiaries in respect of acts or omissions occurring prior to the Effective Time to the extent provided in any written indemnification agreements between Seller and/or one or more its Subsidiaries and such officers and directors and listed in Section 6.7 of the Seller Disclosure Schedule.

(b) At or prior to the Effective Time, Seller shall purchase a “tail” directors’ and officers’ liability insurance policy (which by its terms shall survive the Merger and the Upstream Merger) for its directors and officers, which shall provide such directors and officers with coverage for six (6) years following the Effective Time of not less than the existing coverage under, and have other terms not materially less favorable on the whole to, the insured persons than the directors’ and officers’ liability insurance coverage presently maintained by Seller, so long as the aggregate cost is $210,000 or less. In the event that $210,000 is insufficient

51

for such coverage, Seller may spend up to that amount to purchase such lesser coverage as may be obtained with such amount. Buyer shall, and shall cause the Surviving Corporation to, maintain such policy in full force and effect, and continue to honor the obligations thereunder.

(c) The obligations under this Section 6.7 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 6.7 applies without the consent of such affected indemnitee (it being expressly agreed that the indemnitees to whom this Section 6.7 applies shall be third party beneficiaries of this Section 6.7 and shall be entitled to enforce the covenants contained herein).

(d) In the event Buyer or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of Buyer or the Surviving Corporation, as the case may be, assume the obligations set forth in this Section 6.7.

6.8 Additional Agreements. Subject to the terms and conditions herein provided, in case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities, and franchises of any of the parties to the Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall use its or their reasonable best efforts to take, or cause to be taken, all such necessary action as may be reasonably requested by, and at the sole expense of, Buyer.

6.9 Publicity. Except with respect to any action taken pursuant to and in accordance with Section 6.4, so long as this Agreement is in effect, neither Buyer nor Seller shall, or shall permit any of its respective Subsidiaries to, issue or cause the publication of any press release or other public announcement with respect to, or otherwise make any public statement concerning, the transactions contemplated by this Agreement without the prior written consent of the other party, which consent shall not be unreasonably withheld or delayed, except as may be required by applicable Law or the applicable rules of any stock exchange, in which case the party required to make the release or announcement shall use its reasonable best efforts to allow the other parties reasonable time to comment on such release or announcement in advance of such issuance. Upon the execution of this Agreement and at the Closing, Buyer and Seller shall issue a mutually agreed upon press release announcing the transactions contemplated hereby.

6.10 Notification of Certain Events. Each of Seller and Buyer will give prompt notice to the other of (i) any notice or other communication from any person alleging that the consent of such person is or may be required in connection with the Merger or any of the other transactions contemplated by this Agreement, (ii) any notice or other communication from any Governmental Authority in connection with the Merger or any of the other transactions contemplated by this Agreement, (iii) any litigation relating to, involving or otherwise affecting Seller, Buyer, Merger Sub, Merger LLC or any of their respective Subsidiaries that relates to the Merger or any of the other transactions contemplated by this Agreement. Seller shall give prompt written notice to Buyer of any representation or warranty made by it contained in this Agreement

52

becoming untrue or inaccurate in any material respect, or any failure of Seller to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in any case, if and only to the extent that such untruth or inaccuracy or such failure could reasonably be expected to cause any of the conditions set forth in Section 7.2(a) or Section 7.2(b) to fail to be satisfied at the Closing; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement. Buyer shall give prompt written notice to Seller of any representation or warranty made by it, Merger Sub or Merger LLC contained in this Agreement becoming untrue or inaccurate in any material respect, or any failure of Buyer, Merger Sub or Merger LLC to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in any case, if and only to the extent that such untruth or inaccuracy or such failure could reasonably be expected to cause any of the conditions set forth in Section 7.3(a) or Section 7.3(b) to fail to be satisfied at the Closing; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement.

6.11 Shares Listed. Prior to the Effective Time, Buyer shall obtain approval for listing on Nasdaq the shares of Buyer Common Stock to be issued to the holders of the Seller Common Stock in the Merger.

6.12 Stock Exchange De-listing. Prior to the Closing Date, Seller shall cooperate with Buyer and use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Laws and rules and policies of Nasdaq to enable the delisting by the Surviving Corporation of the Seller Common Stock from Nasdaq and the deregistration of the Seller Common Stock under the Exchange Act as promptly as practicable after the Effective Time, and in any event no more than ten (10) days after the Closing Date.

6.13 Takeover Statutes. If any anti-takeover, control share acquisition, fair price, moratorium or other similar statute is or may become applicable to the Merger or the other transactions contemplated by this Agreement, each of Buyer and Seller and their respective Boards of Directors shall grant such approvals and take such lawful actions as are necessary to ensure that such transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise take such lawful actions to eliminate or minimize the effects of such statute and any regulations promulgated thereunder on such transactions.

6.14 Section 16 Matters. Prior to the Effective Time, Seller and Buyer, as applicable, shall approve in accordance with the procedures set forth in Rule 16b-3 promulgated under the Exchange Act and the Skadden, Arps, Slate, Meagher & Flom LLP SEC No-Action Letter (January 12, 1999) any disposition of equity securities of Seller (including derivative securities), in the case of Seller, and any acquisition of equity securities of Buyer (including derivative securities), in the case of Buyer, resulting from the transactions contemplated by this Agreement by each officer and director of Seller who is subject to the reporting requirements of Section 16(a) of the Exchange Act.

53

6.15 Other Actions by the Parties. Buyer and Seller, at the request of the other party, shall execute and deliver such other instruments and do and perform such other acts and things as may be reasonably necessary or desirable for effecting completely the consummation of this Agreement and the transactions contemplated hereby (including all action reasonably necessary to seek and obtain any and all approvals of any Governmental Authority or other Person required in connection with the Merger or the Upstream Merger; provided, however, that neither Buyer nor (unless approved and so directed by Buyer in advance) Seller shall be obligated to make or consent to any divestiture or operational limitation or activity in connection therewith, or any waiver or modification of any right, or any payment of money or grant of any other commercial concession as a condition to obtaining any such approval). Each party agrees to use commercially reasonable best efforts to cause the conditions set forth in Article VII to be satisfied, where the satisfaction of such conditions depends on action or forbearance from action by such party.

6.16 Financing.

(a) Buyer will use its reasonable best efforts to obtain and close the financing contemplated by the Commitment Letters as soon as commercially reasonable but in any event at or prior to the Closing. In the event that financing pursuant to the Commitment Letters is not available to Buyer for any reason, Buyer shall use reasonable best efforts to obtain and close an alternative financing in an amount sufficient to deliver the Merger Consideration at the Effective Time. Notwithstanding the foregoing, Buyer’s failure to obtain such financing shall not relieve Buyer, Merger Sub and Merger LLC of any of their obligations under this Agreement to consummate the Merger. Buyer will furnish correct and complete copies of drafts of the definitive agreements relating to the financing to the Seller upon receipt thereof and will furnish correct and complete copies when executed.

(b) At the Seller’s request, Buyer shall keep Seller reasonably informed with respect to all material activity concerning the status of the financing contemplated by the Commitment Letters. Without limiting the foregoing, Buyer agrees to notify Seller promptly, and in any event within one (1) Business Day, if at any time prior to the Closing Date the Commitment Letters shall expire or be terminated for any reason.

(c) From the date of this Agreement until the Effective Time, Seller agrees to provide, and shall cause its Subsidiaries to provide, and shall use its reasonable best efforts to cause their respective Representatives to provide, such cooperation as may be reasonably requested by Buyer in connection with the arrangement of, and the negotiation of agreements with respect to, its financing (and any substitutions, replacements or refinancing thereof), including using reasonable best efforts to (i) cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective lenders and due diligence sessions each conducted at the expense of Buyer, and (ii) assist with the preparation of disclosure documents in connection therewith, provided that Seller shall not be obligated to incur any liability to any third party on account thereof and any such assistance shall be at the expense of Buyer.

6.17 Reorganization. Neither Seller, on the one hand, nor Buyer, Merger Sub or Merger LLC, on the other hand, shall take or cause to be taken any action that would prevent the

54

Merger and the Upstream Merger, considered together as a single integrated transaction, from qualifying as a reorganization within the meaning of Section 368(a) of the Code. In the event that the condition in Section 7.3(d) cannot be satisfied because of a failure, as a result of Dissenting Shares and/or cash paid in lieu of fractional shares, of the consideration set forth in Section 2.1(c) to meet the continuity of interest requirement under Section 368(a) of the Code (the “Continuity Requirement”), the Stock Consideration shall be increased and the Cash Consideration shall be decreased to the minimum extent necessary, based on the Exchange Ratio, to enable the Continuity Requirement to be met.

6.18 Tax Due Diligence. Seller and its Subsidiaries shall promptly deliver to Buyer or its Tax advisors such documents and other materials relating to Tax matters which are reasonably requested by such Person(s) in connection with the transactions contemplated by this Agreement. Such documents and materials may include, but not be limited to, correct and complete copies of Tax Returns for any open Tax years filed by Seller and its Subsidiaries, private letter rulings, determination letters, closing agreements and other correspondence issued by any Taxing Authority to Seller or any of its Subsidiaries.

6.19 Director. Immediately following the Effective Time, the Board of Directors of Buyer shall in accordance with provisions contained in Buyer’s certificate of incorporation and bylaws, take such action as necessary to (a) increase the size of the Board of Directors of Buyer by one (1) and (b) elect Zoltan Cendes or a replacement named by the Seller; provided that such nominee or any named replacement shall meet the criteria provided in Buyer’s Corporate Governance Guidelines, as the same may be amended from time to time (such nominee or replacement, the “Designee”) as a Class II Director of the Board of Directors of Buyer to hold office in accordance with Buyer’s certificate of incorporation and bylaws and until his successor is duly elected or qualified, or his earlier death, resignation or removal. The Designee will be subject to Buyer’s Statement of Company Policy on Insider Trading and Disclosure and Insider Trading Procedures and shall execute an acknowledgement to such effect upon the election of the Designee to the Board of Directors of Buyer. In addition, the Designee shall acknowledge Buyer’s Code of Business Conduct and Ethics.

The issuance of such opinion shall be conditioned upon the receipt by such counsel of customary representation letters from each of Buyer, Merger Sub, and Merger LLC, on the one hand, and Seller, on the other hand, in each case, in form and substance reasonably satisfactory to such counsel. Each such representation letter shall be dated on or before the date of such opinion and shall not have been withdrawn or modified in any material respect.

ARTICLE VIII - TERMINATION, AMENDMENT AND WAIVER

Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement, or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

VOTING AGREEMENT

THIS VOTING AGREEMENT (“Agreement”), dated as of March 31, 2008, is made by and between ANSYS, Inc., a Delaware corporation (the “Buyer”), and the undersigned holder (the “Stockholder”) of shares (the “Shares”) of common stock, par value $0.01 per share, of Ansoft Corporation, a Delaware corporation (the “Seller”).

WHEREAS, concurrently with the execution of this Agreement, Buyer, Evgeni, Inc., a Delaware corporation and a wholly owned Subsidiary of Buyer (“Merger Sub”), Sidney LLC, a single member Delaware limited liability company and wholly owned subsidiary of Buyer (“Merger LLC”), and Seller have entered into an Agreement and Plan of Merger, dated of even date herewith (as such agreement may be subsequently amended or modified, the “Agreement and Plan of Merger”), providing for the merger (the “Merger”) of Merger Sub with and into Seller, with Seller to be the surviving corporation of the Merger, which Merger will be followed immediately by a merger of the entity surviving the Merger with and into Merger LLC (the “Upstream Merger”), with the Merger LLC to be the surviving entity in the Upstream Merger;

WHEREAS, the Stockholder beneficially owns (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) and has sole or shared voting power with respect to the number of Shares, and holds stock options or other rights to acquire the number of Shares indicated opposite the Stockholder’s name on Schedule 1 attached hereto;

WHEREAS, it is a condition to the entrance into the Agreement and Plan of Merger that the Stockholder execute and deliver this Agreement on a date even herewith; and

WHEREAS, all capitalized terms used in this Agreement without definition herein shall have the meanings ascribed to them in the Agreement and Plan of Merger.

NOW, THEREFORE, in consideration of, and as a condition to, Buyer entering into the Agreement and Plan of Merger and proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by Buyer in connection therewith, the Stockholder and Buyer agree as follows:

1. Agreement to Vote Shares. The Stockholder agrees that, from and after the date hereof until the Expiration Date (as defined below), at any meeting of the stockholders of Seller or any adjournment thereof, or in connection with any written consent of the stockholders of Seller, with respect to the Merger, the Agreement and Plan of Merger, or any Acquisition Proposal, the Stockholder shall:

(a) appear in person or by proxy at such meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum;

(b) vote (or cause to be voted), or deliver a written consent (or cause a consent to be delivered) covering all of the Shares that such Stockholder shall be entitled to so vote, whether such Shares are beneficially owned by such Stockholder on the date of this Agreement or are subsequently acquired, (i) in favor of adoption and approval of the Agreement and Plan of Merger and all other transactions contemplated by the Agreement and Plan of Merger as to

which stockholders of Seller are called upon to vote or consent; and (ii) against any Acquisition Proposal, or any agreement or transaction providing for the consummation of a transaction contemplated by any Acquisition Proposal.

2. Expiration Date. As used in this Agreement, the term “Expiration Date” shall mean the earlier to occur of (a) the Effective Time, (b) the termination of the Agreement and Plan of Merger pursuant to Article VIII thereof, or (c) upon mutual written agreement of the parties to terminate this Agreement. Upon termination or expiration of this Agreement, no party shall have any further obligations or liabilities under this Agreement; provided, however, such termination or expiration shall not relieve any party from liability for any willful breach of this Agreement prior to termination hereof.

3. Agreement to Retain Shares. From and after the date hereof until the Expiration Date, the Stockholder shall not, except as contemplated by this Agreement or the Agreement and Plan of Merger, directly or indirectly, sell, assign, transfer, or otherwise dispose of (including, without limitation, by the creation of a Lien (as defined below)), or enter into any contract, option, commitment or other arrangement or understanding with respect to the sale, assignment, transfer, or other disposition of, any Shares owned by the Stockholder, whether such Shares are held by the Stockholder on the date of this Agreement or are subsequently acquired prior to any meeting of stockholders held prior to the Expiration Date, whether by the exercise of any stock options to acquire Shares or otherwise. Notwithstanding the foregoing, the Stockholder may make (a) transfers by will or by operation of law, in which case this Agreement shall bind the transferee, (b) transfers in connection with estate and charitable planning purposes, including transfers to relatives, trusts, and charitable organizations, subject to the transferee agreeing in writing to be bound by the terms of, and perform the obligations of the Stockholder under, this Agreement, (c) transfers of shares in connection with the exercise of options to purchase 100,000 Shares within 30 days prior to their expiration in accordance with their terms either (i) with a value after payment of any taxes owed as a result of the transfer, that does not exceed the sum of the option exercise price and minimum withheld tax or (ii) to Seller in a net exercise transaction and (d) as Buyer may otherwise agree in writing in its sole discretion.

4. Representations and Warranties of the Stockholder. The Stockholder hereby represents and warrants to Buyer as follows:

(a) the Stockholder has the power and the right to enter into and perform the terms of this Agreement;

(b) this Agreement (assuming this Agreement constitutes a valid and binding agreement of Buyer) constitutes a valid and binding agreement with respect to the Stockholder, enforceable against the Stockholder in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to creditors’ rights and general principles of equity;

(c) except as set forth on Schedule 1, the Stockholder beneficially owns the number of Shares indicated opposite such Stockholder’s name on Schedule 1, free and clear of any liens, claims, charges or other encumbrances or restrictions (“Liens”), and has sole or shared, and otherwise unrestricted, voting power with respect to such Shares; and

2

(d) the execution and delivery of this Agreement by the Stockholder does not, and the performance by the Stockholder of his or her obligations hereunder and the consummation by the Stockholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which the Stockholder is a party or by which the Stockholder is bound, or any statute, rule or regulation to which the Stockholder is subject or, in the event that the Stockholder is a corporation, partnership, trust or other entity, any bylaw or other organizational document of the Stockholder.

5. Irrevocable Proxy. Subject to the last sentence of this Section 5, by execution of this Agreement, the Stockholder does hereby appoint Buyer with full power of substitution and re-substitution, as the Stockholder’s true and lawful attorney and irrevocable proxy, to the fullest extent of the undersigned’s rights with respect to the Shares, to vote, if the Stockholder is unable to perform his or her obligations under this Agreement, each of such Shares solely with respect to, and in a manner consistent with, the matters set forth in Section 1 hereof. The Stockholder intends this proxy to be irrevocable and coupled with an interest hereunder until the Expiration Date and hereby revokes any proxy previously granted by the Stockholder with respect to the Shares. Notwithstanding anything contained herein to the contrary, this irrevocable proxy shall automatically terminate upon the Expiration Date of this Agreement.

8. No Waivers. No waivers of any breach of this Agreement extended by Buyer to the Stockholder shall be construed as a waiver of any rights or remedies of Buyer with respect to any other stockholder of Seller who has executed an agreement substantially in the form of this Agreement with respect to shares of Seller Common Stock held or subsequently held by such stockholder or with respect to any subsequent breach of the Stockholder or any other such stockholder of Seller. No waiver of any provisions hereof by either party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

9. Governing Law. This Agreement shall be governed by the laws of the State of Delaware, without giving effect to the principles of conflicts of laws thereof. If any provision hereof is deemed unenforceable, the enforceability of the other provisions hereof shall not be affected.

10. Capacity as Stockholder. The Stockholder signs this Agreement solely in the Stockholder’s capacity as a stockholder of Seller, and not in the Stockholder’s capacity as a director, officer or employee of Seller or any of its Subsidiaries or in the Stockholder’s capacity as a trustee or fiduciary of any ERISA plan or trust. Notwithstanding anything herein to the

3

contrary, nothing herein shall in any way restrict a director and/or officer of Seller in the exercise of his or her fiduciary duties consistent with the terms of the Agreement and Plan of Merger as a director and/or officer of Seller or in his or her capacity as a trustee or fiduciary of any ERISA plan or trust or prevent or be construed to create any obligation on the part of any director and/or officer of Seller or any trustee or fiduciary of any ERISA plan or trust from taking any action in his or her capacity as a director of Seller.

11. No Agreement Until Executed.

ANSYS, INC. SIGNS DEFINITIVE AGREEMENT TO ACQUIRE ANSOFT CORPORATION

Acquisition Broadens Capabilities as a Global Innovator of Simulation Software

SOUTHPOINTE, Pa. and PITTSBURGH, Pa., March 31, 2008 /Prime Newswire/ — ANSYS, Inc. (NASDAQ: ANSS), a global innovator of simulation software and technologies designed to optimize product development processes, and Ansoft Corporation (NASDAQ: ANST), a global provider of Electronic Design Automation (EDA) software, announced today that they signed a definitive agreement whereby ANSYS will acquire Ansoft for a purchase price of approximately $832 million in a mix of cash and ANSYS common stock. The strategic, complementary business combination of ANSYS and Ansoft will create the leading provider of ‘best-in-class’ simulation capabilities, with combined trailing 12-month revenues of $485 million. When completed, ANSYS currently anticipates that the transaction will be modestly accretive to non-GAAP earnings per share in its first full year of combined operations.

Under the terms of the definitive agreement, which was unanimously approved by the Boards of Directors of both companies, Ansoft stockholders will receive $16.25 in cash and 0.431882 shares of ANSYS common stock for each outstanding Ansoft share. Based on the 10-day trailing average closing price of ANSYS common stock, the implied value is $32.50 per Ansoft share. ANSYS will issue an aggregate of approximately 11.1 million shares of its common stock and pay an aggregate of approximately $416 million in cash in the transaction. ANSYS intends to fund the cash portion of the transaction with approximately $70 million of cash on-hand from the combined organization and approximately $346 million from the proceeds of a $450 million unsecured senior term loan credit facility. ANSYS’ current lender, Bank of America, N.A., has committed to fully underwriting the credit facility and Banc of America Securities LLC has agreed to act as lead arranger. The pricing of the senior credit facility is tier based with limited market flexibility on yields and structure to facilitate its syndication. The transaction, currently anticipated to close in the second calendar quarter of 2008, is subject to customary closing conditions, regulatory approvals and approval by the Ansoft stockholders. In connection with the execution of the definitive agreement, certain Ansoft stockholders, who collectively beneficially own approximately 16% of Ansoft, entered into voting agreements agreeing to vote for the proposed transaction. Upon the closing of the transaction, Ansoft stockholders will own approximately 12% of the combined company on a pro forma basis. After the closing, Ansoft will become a wholly-owned subsidiary of ANSYS and Ansoft common stock will cease trading on Nasdaq.

Ansoft is a leading developer of high-performance EDA software. The software is based on more than 25 years of research and development by world-renowned experts in electromagnetics, circuit and system simulation. Engineers use Ansoft products to simulate high-performance electronics designs found in mobile communication and internet devices, broadband networking components and systems, integrated circuits, printed circuit boards and electromechanical systems. The company’s products are used by blue chip companies as well as small and medium sized enterprises around the world.

The acquisition of Ansoft is ANSYS’ first foray into the broader EDA software industry and will enhance the breadth, functionality, usability and interoperability of the combined ANSYS portfolio of engineering simulation solutions. The combination is expected to increase operational efficiency and lower design and engineering costs for customers, and accelerate development and delivery of new and innovative products to the marketplace. The complementary combination of Ansoft’s and ANSYS’ software products and services is expected to give ANSYS one of the most complete, independent engineering simulation software offerings in the industry, reaffirming and strengthening ANSYS’ commitment to open interface and flexible simulation solutions that are primarily driven by customer demand, flexibility and choice. With over 40 direct sales offices and 21 development centers on three continents, the combined company will employ approximately 1,700 people.

“We are very excited about the state-of-the-art technologies that Ansoft adds to ANSYS’ simulation capabilities,” said James E. Cashman III, President and Chief Executive Officer of ANSYS. “Both companies have a strong commitment to their customers and employees, and share a passion for the development of innovative products and services and a history of world-class execution. This combination will further strengthen these values and will allow us to better serve our customers by accelerating the delivery of comprehensive, customer-driven engineering simulation solutions and by enabling us to provide high quality support throughout the world. We see this as an opportunity to add highly complementary physics that address the convergence of mechanical and electrical engineering product design and development. We are also excited about bringing two great Pittsburgh-based companies together to create an exciting opportunity for aspiring engineers, computer scientists and professionals to join us in our mission to democratize the use of simulation across the globe.”

“The simulation technologies that Ansoft adds complement and broaden the existing ANSYS portfolio of simulation solutions, enabling the combined company to deliver the integration, efficiency, functionality and interoperability required by customers across a broad range of industries and applications. With trailing 12-month revenues ending January 31, 2008 of $98 million, Ansoft brings a combination of new software revenue growth and strong operating margins. Ansoft’s solid revenue and customer base, combined with its profitability, should enable the transaction to be modestly accretive to non-GAAP earnings per share in our first full year of combined operations and accretive beyond that,” stated Cashman.

“This merger brings together two great companies with a shared vision and strong engineering focus,” said Dr. Zoltan J. Cendes, the founder, Chairman of the Board and Chief Technology Officer of Ansoft. “The combination of our R&D teams, complementary technological strengths and our commitment to quality will enhance our ability to deliver comprehensive, innovative, world-class simulation software technologies that customers demand.” In conjunction with this transaction, Dr. Cendes will join ANSYS’ Board of Directors following the closing of the transaction.

“The combination of Ansoft’s extensive portfolio of electromagnetics, circuit and systems simulation solutions with ANSYS’ existing simulation capabilities creates a ‘best of breed’ company that will continue to lead the evolution and innovation of engineering simulation by enabling customers to improve their product development processes, eliminate physical prototypes, reduce time-to-market for new products and improve product innovation and performance,” said Nicholas Csendes, President and Chief Executive Officer of Ansoft.

Integration

The two Pittsburgh-based companies are developing integration plans that leverage and build on the cultural similarities and the best practices from each team. ANSYS will provide additional details relative to the acquisition and integration activities subsequent to the closing of the transaction.

Due to the absence at this time of estimates of the acquisition-related impact of purchase accounting adjustments, including the allocation of the purchase price among goodwill, in-process R&D, other intangibles and equity-based compensation expenses related to SFAS 123R, ANSYS is currently unable to provide GAAP estimates on future earnings. The company intends to provide updated GAAP and non-GAAP financial guidance after the closing of the transaction.

Advisors

In connection with the transaction, Deutsche Bank Securities Inc. is acting as exclusive financial advisor to Ansoft, and Wilson Sonsini Goodrich & Rosati, Professional Corporation is acting as legal counsel. Goodwin Procter LLP is acting as legal counsel to ANSYS.

Ansoft Transaction Highlights

March 31, 2008

EX-99.3

Exhibit 99.3

March 31, 2008

Dear Colleagues,

Today is a great day for our company and for the company we hope to become – one that we hope each of you will celebrate.

This morning, we announced the signing of a definitive agreement for the acquisition of Ansoft Corporation by ANSYS, Inc. Attached is a copy of our press release and we encourage you to read it.

This is a logical strategic step at an optimal time to create compelling value for our customers, our stockholders, and for you, our employees. The extraordinary efforts you collectively have made to build our company have brought us to this day. Soon we will need to focus those efforts towards a greater goal of a combined company delivering superior products and value to our customers.

Allow us to share a few key areas of today’s exciting announcement:

Reason: There are many reasons this agreement makes sense for ANSYS and Ansoft:

• The acquisition of Ansoft is expected to further supplement and extend the ANSYS engineering simulation technologies and customer presence.

• Ansoft’s and ANSYS’ software technologies are expected to give the combined company the most complete and complementary independent set of engineering simulation software offerings in the CAE industry.

• There is no doubt that the mechanical and electronic CAE worlds are converging and customers are demanding broader and more robust solutions. This acquisition broadens our portfolio and well positions our multiphysics simulation tools.

Timing of Events and Next Steps: Even though we made the announcement today, it will be some time before the transaction can be closed. An integration team comprised of leaders from both companies will be formed over the coming weeks to determine the best approach for continued, but accelerated, success after the transaction closes. Other announcements regarding leadership alignments will be communicated as we progress through the closing and post-

closing integration processes. Prior to closing, this integration team will be working on certain aspects of how to best combine the capabilities of our respective businesses as we seek the appropriate approvals.

Despite this limited work on integration planning, it is critical that from now until the acquisition is completed, ANSYS and Ansoft continue to operate independently and conduct their businesses as usual. We will provide updates on a regular basis as we reach key milestones in the approval process and beyond.

We are excited about this new opportunity presented by the combination of two world class providers of innovative simulation technologies. Each brings a unique perspective on the development of critical product development technologies, and combined should provide our customers considerable flexibility and choice in how they deploy key simulation resources.

Please take time to read and understand all the information about this exciting development. We know it’s a lot to absorb and that change of this magnitude can be unsettling, but I think we have demonstrated that it can also be fulfilling. We have made available the attached Information for Employees to begin to address some of the questions you may have at this time. You have our commitment that as we move forward, we will try to provide timely updates.

We should all be proud of our execution over the past several years; it has truly enabled us to open up great possibilities for our customers, our stockholders, our partners and you, our employees.

Thank you again,

James E. Cashman III

President and Chief Executive Officer

ANSYS, Inc.

Certain statements contained in this communication regarding matters that are not historical facts, including statements regarding the convergence of the mechanical and electronic CAE worlds, the impact of the pending acquisition, including the creation of value for customers, stockholders and employees, the combined company’s ability to further supplement and extend technologies and customer presence and deliver engineering simulation software offerings, the impact on our portfolio and positioning of our multiphysics simulation tools, and the transaction leading to considerable flexibility and choice for our customers, the success of our integration following the closing of the proposed transaction and the impact of the transaction on employees and our operational plans, are “forward-looking” statements (as defined in the Private Securities Litigation Reform Act of 1995). Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements.

1

stock for each share of Ansoft common stock outstanding. ANSYS will use a combination of existing cash and new debt for the cash portion of the purchase price. The transaction is subject to customary closing conditions.

Q4. What are the closing conditions? The transaction is subject to customary closing conditions, including regulatory approval and approval by the Ansoft stockholders. Ansoft’s Board of Directors has approved the transaction and certain of its principal stockholders have agreed to vote in favor of the transaction. The Ansoft Board is recommending that Ansoft stockholders approve the transaction. The transaction does not require an ANSYS stockholder vote.

Q5. How was the purchase price determined? ANSYS used several valuation methodologies (including discounted cash flow analysis and trading and transaction multiples among others) to value Ansoft. Ultimately, the two companies developed a common understanding of relative value that was supported by a variety of financial and other analyses. ANSYS and Ansoft were also advised by their respective financial advisors that the purchase price is fair, from a financial point of view, to the stockholders of ANSYS and Ansoft.

Q6. What is the strategic rationale underlying the ANSYS and Ansoft combination? The acquisition of Ansoft adds leading edge EDA technologies to ANSYS’ broad portfolio of mechanical, fluids and dynamics simulation solutions, and is expected to enhance the breadth, functionality, usability and interoperability of the ANSYS suite of engineering simulation software. In addition, the combination brings together two companies with complementary cultures that are committed to innovation and have demonstrated track records of execution. Together, Ansoft’s and ANSYS’ software products and services are expected to give ANSYS one of the broadest independent engineering simulation software offerings in the industry with over 15,000 total customers, including 96 of the Fortune 100 Industrial Companies. The direct and indirect sales presences of the two companies are largely complementary and will provide an increased global presence for ANSYS. The combination joins two teams with deep industry expertise and world-class engineering talent. Approximately 15% of revenue is spent on R&D, and the combined entity will have 21 major development centers on three continents. Both companies share a focus on bottom-line performance and have strong top-line growth profiles.

Q7. How will ANSYS account for the acquisition? It will be accounted for as a purchase transaction under US GAAP. At closing, ANSYS will recognize cash and non-cash charges related to the transaction in addition to certain acquisition-related amortization expenses, as well as possible in-process R&D or deferred revenue purchase accounting adjustments. ANSYS will provide more detail on these purchase accounting adjustments and their impact on ANSYS’ GAAP results upon the closing of the transaction.

Q8. How will ANSYS finance the acquisition? The cash consideration of approximately $416 million will be financed through a combination of existing cash and new bank debt of up to $450 million. ANSYS will also issue approximately 11.1 million new shares of ANSYS common stock for the stock portion of the purchase price.

Q9. What kind of due diligence did the parties conduct? Under the guidance of legal counsel, the two management teams and their respective advisors have engaged in extensive business, financial and legal due diligence.

Q10. How will the transaction impact ANSYS stockholders and creditors? The transaction is expected to be modestly accretive to non-GAAP earnings per share in the first full year of combined operations and accretive beyond that. Debt remaining from ANSYS’ acquisition of Fluent will be refinanced as part of this financing. We believe the combined business will deliver sufficient cash flow to meet ANSYS’ new debt obligations.

Q11. How much stock will the current stockholders own in the combined company? Upon closing, current ANSYS stockholders will own approximately 88% and current Ansoft stockholders will own approximately 12% of the combined company’s outstanding shares on a fully diluted basis.

Until closing, it is business as usual for everyone. ANSYS and Ansoft are to independently pursue business opportunities until we have completed the steps necessary to close this transaction. Based on this, it is important that opportunities, pipeline, account information, sales plans, and certain other confidential information are not shared between the two organizations. It is also important for customers to know and understand that we cannot discuss or provide joint

9

proposals or solutions until this transaction is formally completed. However, as noted earlier, any customer of the combined company following the closing of the transaction will be very well positioned to benefit from this transaction.

We will be proactive and positive in engaging customers in conversations about this announcement. However, we cannot speculate in answering their questions. If the answer is not contained in the information provided today then you should tell them that we do not know as of today, but those decisions/answers will be made as we move forward and will be provided at that point in time.

Please note that additional information about this transaction will be made available in a prospectus/proxy statement that will be filed with the U.S. Securities and Exchange Commission in the coming weeks. The prospectus/proxy statement and the other public filings of ANSYS and Ansoft will all be publicly available at www.sec.gov and in the “Investors” section of the ANSYS’ website at www.ansys.com and in the “Investor Relations” section of the Ansoft website at www.ansoft.com. It is important that you refrain from discussions and other communications regarding this transaction with customers or other third parties, other than by reference to the information that ANSYS or Ansoft have made publicly available. Any questions in this regard should be directed to Annette Arribas, ANSYS’ Investor Relations Officer, at annette.arribas@ansys.com or Mark Ravenstahl at mravenstahl@ansoft.com.

EMPLOYEES

Q1. How will the acquisition affect me as an ANSYS or Ansoft employee? Until the acquisition closes, there will be no changes to employee benefits, compensation or employment policies as a result of the transaction. Business at each company will continue as usual. For instance, Ansoft employees will remain on their current health insurance and other benefit plans at least until the closing of the transaction. Also, if an ANSYS or Ansoft employee was slated to receive a bonus based on respective 2007 or fiscal 2008 performance or a salary adjustment before the acquisition closes, he or she will still receive the bonus or adjustment.

10

Employees may be concerned about whether there will be workforce reductions or office closings. The Integration Team, to be comprised of key leaders from ANSYS and Ansoft, will need some time following the closing of the transaction to let the companies work together in order to assess whether there are duplicative job positions or office locations. Accordingly, there are no plans at this time for any lay-offs as a result of the transaction. We will be examining opportunities to consolidate and re-deploy our resources most efficiently, and we are hopeful that any duplicative staffing that could result from operational synergies between the companies can be re-deployed in line with the combined company’s future direction. At this time we do not foresee any major impacts on the combined work force. As the Integration Team works through the transition, we will have a better understanding of this important issue and will keep employees apprised of the situation.

The Integration Team will determine whether some or all of the existing Ansoft benefit plans (for example, health insurance plans, 401(k) plan) and employment policies (such as the Ansoft Employee Handbook) should be left in place or whether Ansoft employees should be transitioned to some or all of the existing ANSYS benefit plans and policies. Any such changes, of course, will be made post-closing in accordance with the applicable law of each country and locality in which the combined company will operate. Additional information on employee benefits will be provided to you as these transition issues are addressed.

Q2. What happens to my stock options? If you are an ANSYS employee, there will be no change to your outstanding stock options as a result of this transaction. If you are an Ansoft employee, two things will happen with your options at the closing. First, all of your options will become fully vested. Second, your options to acquire Ansoft stock will become options to acquire ANSYS stock. In the merger, Ansoft stockholders will receive 0.431882 shares of ANSYS stock and $16.25 in cash for each share of Ansoft stock they hold. Given tax and other factors, option holders will not receive cash in the transaction. The number of shares of ANSYS stock to which your Ansoft option will entitle you is determined by the option exchange ratio set forth in the merger agreement. Each Ansoft option will be converted into the right to receive the number of shares subject to the Ansoft option multiplied by the option exchange ratio, rounded down to the

11

nearest whole share. The sum of the 0.431882 shares of ANSYS stock and a number of ANSYS shares constituting the $16.25 in value (based off the average closing price of the ANSYS stock for the 30 day period prior to the closing) is the “option exchange ratio”. The new exercise price for Ansoft options will equal the old exercise price, divided by the option exchange ratio, rounded up to the nearest whole cent.

The following example demonstrates how Ansoft options will be treated. Assume an employee owns options to acquire 100 shares of Ansoft stock with an exercise price of $10. Also assume the average closing price for the ANSYS stock during the 30 trading day period prior to the closing equals $37.90. The number of ANSYS shares that will become subject to the employee’s options equals: 100*(($16.25+(0.431882*37.90))/37.90) = 86. The new exercise price of the options equals: $10/(($16.25+(0.431882*37.90))/37.90) = $11.62.

Q3. When will the integration process begin? As soon as the acquisition closes the integration process will begin. Some transition planning has already begun. The Integration Team will be comprised of key leaders from ANSYS and Ansoft to be announced over the next several weeks.

Q4. Are the corporate cultures very different? No. In fact, the similarities are remarkable. Both ANSYS and Ansoft have been operating as public companies since 1996, both are headquartered in the Pittsburgh, Pennsylvania area, and both companies have demonstrated their focus on engineering simulation technology and their commitment to customers, employees and partners. Of course, each company has its own unique nuances that will require some time to understand and appreciate. However, no combination of this magnitude can occur without some changes, which we view as a positive opportunity.

Q5. Are transfers and relocation between offices and roles possible? Yes, although no specific plans are in place. Such opportunities are highly dependent upon company needs and integration plans.

Q6. Are there certain things employees can and cannot do between today and when the transaction closes? You are to continue conducting business independently as usual. Some of you will also be engaged in integration planning; however, no coordination or integration

12

implementation can occur prior to closing. It is important that opportunities, pipeline, account information, sales plans, and certain other confidential information are not shared between the two organizations. It is also important for customers to know and understand that we cannot discuss or provide joint proposals or solutions until this transaction is formally completed.

Q7. Will budgets be affected at all? Are there any restrictions on spending? All spending plans will be examined as a part of the integration process.

Q8. How many employees does Ansoft have? Ansoft and its subsidiaries have approximately 300 employees worldwide. Offices are located in the United States, France, Germany, Italy, Sweden, United Kingdom, China (PRC), Japan, Korea, Singapore and Taiwan.

Q9. How many employees does ANSYS have? ANSYS and its subsidiaries have approximately 1,400 employees worldwide. Offices are located in the United States, Canada, France, Germany, Italy, Belgium, Netherlands, Sweden, Japan, India and China. In addition to its direct sales offices, ANSYS distributes and supports its products through a global network of channel partners. This highly experienced channel of distribution and technical support currently provides approximately 30% of ANSYS’ revenues.

Q10. How does Ansoft fit into the overall structure at ANSYS? Ansoft will remain a separate subsidiary after closing.

Q11. Can I communicate with employees of the other company? Until the acquisition closes both companies must pursue business opportunities and serve their respective customers independently. Some employees will be part of integration planning teams, but no coordination or integration implementation can occur prior to closing. It is important that opportunities, pipeline, account information, sales plans, and certain other confidential information are not shared between the two organizations. It is also important for customers to know and understand that we cannot discuss or provide joint proposals or solutions until this transaction is formally completed.

13

Q12. Where can I learn more about the acquisition?

Exhibit 99.5

March 31, 2008

Dear ANSYS Customer,

As you may have come to expect, ANSYS, Inc. continues to bring together world class companies and technologies to deliver on the vision of Simulation Driven Product Development. Today we have announced our intention to acquire Ansoft Corporation. Ansoft is a world leader in delivering engineering simulation solutions to the electronics industry across a broad set of applications. This is an exciting day for ANSYS and, we believe, for you as an ANSYS engineering software user. Ansoft’s impressive and complementary technologies will be a tremendous addition to the ANSYS portfolio of simulation software tools.

Ansoft customers are receiving a communication from Nick Csendes, President and CEO of Ansoft, and Dr. Zol Cendes, founder, Chairman of the Board and CTO, expressing their excitement about this opportunity. In asking them to convey my personal excitement to the Ansoft user community, I also wanted to take this opportunity to address our loyal ANSYS customers.

Strategically, this acquisition will add world class EDA technology to the existing ANSYS broad portfolio of mechanical and fluids simulation technology and demonstrates our commitment to offering industry leading simulation solutions both in terms of depth and breadth. The ANSYS vision of Simulation Driven Product Development is significantly enhanced with the addition of Ansoft’s technology. Post-close, we will quickly explore opportunities for integrating into the ANSYS^® Workbench™ platform, which is the foundation for this vision. Our acquisition of Ansoft also enhances two of the cornerstones of our vision—our commitments to Advanced Technology and to delivering comprehensive MultiPhysics based on world class simulation technology. The advancement of all ANSYS technology will continue to be fully supported by our continued commitment to R&D investments across the entire portfolio.

Upon closure of this acquisition, ANSYS will begin to integrate Ansoft – functionally, geographically, technically. Of immediate benefit will be the opportunity for tighter linkages between ANSYS Workbench-based products, such as ANSYS Mechanical, CFD and Multiphysics, and the current array of Ansoft electronics solutions. We have continued to integrate across our entire existing product portfolio consistent with our strategy and vision. The benefits of this strategy to our customers and the engineering simulation industry have been real and very measurable in terms of increased innovation, greater productivity, higher efficiency and lower costs. We fully expect to offer the same benefit potential to today’s Ansoft user community.

It is important to note that prior to this transaction closing, each company will continue to operate completely independently. We expect this process to last until the second calendar quarter of 2008, during which time ANSYS will continue to provide you with the same outstanding customer service you are accustomed to receiving. We appreciate your patience and thank you in advance for respecting the need for due process in these matters.

This is an exciting announcement for all of us at ANSYS. More importantly, this is an exciting and positive event for our customers and the engineering simulation community in general. I sincerely hope that you share in our enthusiasm. We look forward to the opportunity to discuss this with you firsthand, so please do not hesitate to contact your local Regional Sales Director if you have any questions.

Yours very truly,

/s/ James E. Cashman III
