AGREEMENT AND PLAN OF MERGER AND REORGANIZATION

THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION (“Agreement”) is made and entered into as of February 23, 2004, by and among: SYNOPSYS, INC., a Delaware corporation (“Parent”); MOUNTAIN ACQUISITION SUB, INC., a Delaware corporation and a wholly owned subsidiary of Parent (“Acquisition Sub”); and MONOLITHIC SYSTEM TECHNOLOGY, INC., a Delaware corporation (the “Company”). Certain capitalized terms used in this Agreement are defined in Exhibit A.

RECITALS

A. Parent, Acquisition Sub and the Company have determined that it is in the best interests of their respective stockholders for Parent to acquire the Company upon the terms and subject to the conditions set forth in this Agreement.

B. In furtherance of the contemplated acquisition of the Company by Parent, it is proposed that Acquisition Sub make an exchange offer to acquire all of the issued and outstanding shares of Company Common Stock upon the terms and subject to the conditions set forth in this Agreement. (Such exchange offer, as it may be amended from time to time, and as it may be modified to reflect the election referred to in Section 1.1(b) (if such election is made), is referred to in this Agreement as the “Offer.”)

C. If Acquisition Sub does not make the election referred to in Section 1.1(b) (the election referred to in Section 1.1(b) being referred to in this Agreement as the “All-Cash Election”), then each share of Company Common Stock accepted for exchange pursuant to the Offer will be exchanged for (i) $6.75, net to the seller in cash (the “Exchange Offer Cash Amount”), and (ii) a fraction of a share of Parent Common Stock having a numerator equal to the Exchange Offer Cash Amount and having a denominator equal to the Parent Average Stock Price (the “Applicable Fraction”). If Acquisition Sub makes the All-Cash Election, then the Offer will become a cash tender offer and Acquisition Sub will pay $13.50, net to the seller in cash (the “All-Cash Dollar Amount”), for each share of Company Common Stock accepted for payment pursuant to the Offer.

D. It is further proposed that, after acquiring shares of Company Common Stock pursuant to the Offer, Acquisition Sub merge into the Company upon the terms and subject to the conditions set forth in this Agreement (the merger of Acquisition Sub into the Company being referred to in this Agreement as the “Merger”).

E. If Acquisition Sub does not make the All-Cash Election, then (a) following the Merger, Parent has agreed to adopt an agreement and plan of merger and reorganization pursuant to which the Surviving Corporation (as defined in Section 2.1) will merge into Parent or, at Parent’s election, into a wholly owned subsidiary of Parent (the merger of the Surviving Corporation into Parent or a wholly owned subsidiary of Parent being referred to in this Agreement as the “Second Merger”), with Parent or such subsidiary being the surviving corporation of the Second Merger, and (b) it is intended that the Offer, the Merger and the Second Merger would together qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”).

F. In order to induce Parent and Acquisition Sub to enter into this Agreement and to consummate the Contemplated Transactions, concurrently with the execution and delivery of this Agreement certain stockholders of the Company are executing and delivering stockholder agreements in favor of Parent and Acquisition Sub (the “Stockholder Agreements”).

AGREEMENT

The parties to this Agreement, intending to be legally bound, agree as follows:

Section 1. THE OFFER

1.1 Conduct of the Offer.

(a) Acquisition Sub shall commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer as promptly as reasonably practicable after the date of this Agreement (and shall use reasonable efforts to commence the Offer within ten business days after the public announcement of the terms of this Agreement); provided, however, that (i) Acquisition Sub shall not be required to commence the Offer if any of the conditions set forth in clauses “(d),” “(j),” “(n),” “(p)” and “(q)” of Exhibit B shall not then be satisfied, (ii) if any of the conditions set forth in clauses “(a),” “(b),” “(c),” “(k),” “(l),” “(m)” and “(o)” of Exhibit B shall not then be satisfied, then Acquisition Sub shall not be required to commence the Offer until such time as each of said conditions is satisfied (at which time the Offer shall be commenced unless Acquisition Sub is not then required to commence the Offer by virtue of clause “(i),” clause “(iii)” or clause “(iv)” of this proviso), (iii) Acquisition Sub shall not be required to commence the Offer if an event shall have occurred or a circumstance shall exist that, in the reasonable judgment of Parent, would make any of the conditions set forth in Exhibit B incapable of being satisfied on or prior to the expiration date of the Offer (as it may be extended pursuant to Section 1.1(e)), and (iv) Acquisition Sub shall not be required to commence the Offer if the Company shall not be prepared to file immediately with the SEC, and to disseminate to holders of shares of Company Common Stock, the Schedule 14D-9 (as defined in Section 1.2(c)). (The date on which Acquisition Sub commences the Offer, within the meaning of Rule 14d-2 under the Exchange Act, is referred to in this Agreement as the “Offer Commencement Date.”)

(b) Acquisition Sub may make the All-Cash Election at any time (whether before or after commencement of the Offer), but in no event less than two business days prior to the expiration date of the Offer (as it may be extended pursuant to Section 1.1(e)). To make the All-Cash Election, Acquisition Sub shall cause to be issued a press release disclosing that Acquisition Sub is changing the Offer from an exchange offer to a cash tender offer pursuant to the provisions of this Agreement. Acquisition Sub shall cause a copy of such press release to be provided to the Company promptly after it is issued. Notwithstanding anything to the contrary contained in this Agreement, if Acquisition Sub makes the All-Cash Election, then (i) all obligations of Parent and Acquisition Sub with respect to the Registration Statement (as defined in Section 1.1(g)), with respect to the Preliminary Prospectus (as defined in Section 1.1(g)) and with respect to the Post-Effective Amendment shall terminate and cease to be of any force or effect, and neither Parent nor Acquisition Sub shall have any liability with respect thereto, (ii) all obligations of Parent and Acquisition Sub with respect to the issuance, delivery and listing of shares of Parent Common Stock shall terminate and shall cease to be of any force or effect, and neither Parent nor Acquisition Sub shall have any liability with respect thereto, and (iii) the representations and warranties set forth in Sections 4.2 and 4.3, and the representations and warranties set forth in Section 4.8 (as they relate to the Registration Statement and the Post-Effective Amendment), shall cease to be of any force or effect, and neither Parent nor Acquisition Sub shall have any liability with respect thereto. The All-Cash Election, once made by Acquisition Sub, shall be irrevocable, and thereafter Acquisition Sub will pay only the All-Cash Dollar Amount for each share of Company Common Stock validly tendered and accepted for payment in the Offer, and the Per Share Consideration shall be only the All-Cash Dollar Amount.

(c) The obligation of Acquisition Sub to accept for exchange or payment (and the obligation of Parent to cause Acquisition Sub to accept for exchange or payment) shares of Company Common Stock validly tendered (and not withdrawn) pursuant to the Offer shall be subject only to (i) the condition (the “Minimum Condition”) that there shall be validly tendered (and not withdrawn) a number of shares of Company Common Stock that, together with any shares of Company Common Stock owned by Parent or Acquisition Sub immediately prior to the acceptance for exchange or payment of shares of Company Common Stock pursuant to the Offer, represents

more than 50% of the Adjusted Outstanding Share Number (as defined below) and (ii) the other conditions set forth in Exhibit B. (The Minimum Condition and the other conditions set forth in Exhibit B are referred to collectively as the “Offer Conditions.”) For purposes of this Agreement, the “Adjusted Outstanding Share Number” shall be the sum of (1) the aggregate number of shares of Company Common Stock issued and outstanding immediately prior to the acceptance of shares of Company Common Stock for exchange or payment pursuant to the Offer, plus (2) the aggregate number of shares of Company Common Stock issuable upon the exercise of all vested options, warrants and other rights to acquire Company Common Stock that are outstanding immediately prior to the acceptance of shares of Company Common Stock for exchange or payment pursuant to the Offer.

(d) Acquisition Sub expressly reserves the right, in its sole discretion, to (i) increase the Per Share Consideration and (ii) waive or make any other changes to the terms and conditions of the Offer; provided, however, that without the prior written consent of the Company: (A) the Minimum Condition may not be amended or waived; (B) except in connection with the All-Cash Election, no change may be made to the Offer that changes the form of consideration to be delivered by Acquisition Sub pursuant to the Offer or decreases any component of the Per Share Consideration; and (C) no change may be made to the Offer that (1) decreases the number of shares of Company Common Stock sought to be purchased by Acquisition Sub in the Offer, (2) imposes conditions to the Offer in addition to the Offer Conditions, or (3) except as provided in Section 1.1(e), extends the expiration date of the Offer beyond the initial expiration date of the Offer. Subject to the terms and conditions of the Offer and this Agreement, Acquisition Sub shall, and Parent shall cause Acquisition Sub to, (x) accept for exchange or payment all shares of Company Common Stock validly tendered (and not withdrawn) pursuant to the Offer as soon as practicable after Acquisition Sub is permitted to do so under applicable Legal Requirements and (y) deliver the Per Share Consideration in exchange for each share of Company Common Stock accepted for exchange or payment pursuant to the Offer.

(e) The Offer shall initially be scheduled to expire 20 business days following the Offer Commencement Date (calculated as set forth in Rule 14d-1(g)(3) and Rule 14e-1(a) under the Exchange Act). Notwithstanding anything to the contrary contained in this Agreement, but subject to the parties’ respective termination rights under Section 8.1: (i) if, on any date as of which the Offer is scheduled to expire, any Offer Condition is not satisfied and has not been waived, Acquisition Sub may, in its discretion (and without the consent of the Company or any other Person), extend the Offer, on one or more occasions for an additional period of up to 20 business days per extension, to permit such Offer Condition to be satisfied; (ii) Acquisition Sub may, in its discretion (and without the consent of the Company or any other Person), extend the Offer from time to time for any period required by any rule or regulation of the SEC applicable to the Offer; (iii) if Acquisition Sub makes the All-Cash Election, then Acquisition Sub may, in its discretion (and without the consent of the Company or any other Person), extend the Offer for a period of 10 business days after the date on which materials disclosing that Acquisition Sub has made the All-Cash Election are disseminated to the Company’s stockholders; (iv) if, on any date as of which the Offer is scheduled to expire, the Minimum Condition is satisfied but the sum of the number of shares of Company Common Stock that have been validly tendered (and not withdrawn) pursuant to the Offer and the number of shares of Company Common Stock owned by Parent or Acquisition Sub is less than 90% of the number of shares of Company Common Stock outstanding, then Acquisition Sub may, in its discretion (and without the consent of the Company or any other Person), extend the Offer for one additional period of not more than 10 business days; provided, however, that if Acquisition Sub extends the Offer pursuant to this clause “(iv),” thereafter the obligation of Acquisition Sub to accept for exchange or payment, and to deliver consideration in exchange for, shares of Company Common Stock validly tendered (and not withdrawn) pursuant to the Offer shall be subject only to the conditions set forth in clauses “(e),” “(f)” and “(j)” of Exhibit B; and (v) Acquisition Sub may, in its discretion (and without the consent of the Company or any other Person), elect to provide for a subsequent offering period (and one or more extensions thereof) in accordance with Rule 14d-11 under the Exchange Act. Subject to the parties’ respective termination rights under Section 8.1, if (A) each the Offer Conditions set forth in clauses “(a),” “(b),” “(c),” “(d),” “(j),” “(k),” “(l),” “(m),” “(n),” “(o),” “(p)” and “(q)” of Exhibit B is satisfied or has been waived on any date as of which the Offer is scheduled to expire, or Acquisition Sub reasonably determines that all of such Offer Conditions are likely to be satisfied

within 15 business days after such date, and (B) any of the other Offer Conditions is not satisfied and has not been waived on such date, then, to the extent requested in writing by the Company no less than two business days prior to such date, Acquisition Sub shall extend the Offer beyond such date for an additional period of up to 20 business days, provided that in no event shall Acquisition Sub be required to extend the Offer to a date later than July 31, 2004.

(f) No fractional shares of Parent Common Stock shall be issued in connection with the Offer, and no certificates or scrip for any such fractional shares shall be issued in connection with the Offer. Any holder of Company Common Stock who would otherwise be entitled to receive a fraction of a share of Parent Common Stock in the Offer (after aggregating all fractional shares of Parent Common Stock issuable to such holder in the Offer) shall, in lieu of such fraction of a share, be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the closing trading price of a share of Parent Common Stock as reported on the Nasdaq National Market on the trading day immediately before the Acceptance Date.

(g) As soon as practicable after the date of this Agreement, unless the All-Cash Election shall have been made, Parent shall prepare and file with the SEC a registration statement on Form S-4 to register the offer and sale of Parent Common Stock pursuant to the Offer (the “Registration Statement”). The Registration Statement will include a preliminary prospectus containing the information required under Rule 14d-4(b) under the Exchange Act (the “Preliminary Prospectus”). On the Offer Commencement Date, Parent and Acquisition Sub shall: (i) cause to be filed with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer, which will contain or incorporate by reference the Preliminary Prospectus and forms of the related letter of transmittal and summary advertisement (such Tender Offer Statement on Schedule TO and all exhibits, amendments and supplements thereto being referred to collectively in this Agreement as the “Offer Documents”); and (ii) cause the Offer Documents to be disseminated to holders of shares of Company Common Stock to the extent required by applicable federal securities laws. Parent and Acquisition Sub shall use reasonable efforts to cause the Registration Statement and the Offer Documents and the to comply in all material respects with the applicable requirements of the Exchange Act and the Securities Act and the rules and regulations thereunder. The Company and its counsel shall be given reasonable opportunity to review and comment on the Registration Statement and the Offer Documents (including all amendments and supplements thereto) prior to the filing thereof with the SEC. Parent and Acquisition Sub shall promptly provide the Company and its counsel with a copy or a description of any comments received by Parent, Acquisition Sub or their counsel from the SEC or its staff with respect to the Registration Statement or the Offer Documents. Each of Parent and Acquisition Sub shall use reasonable efforts to respond promptly to any comments of the SEC or its staff with respect to the Registration Statement, the Offer Documents or the Offer. To the extent required by the applicable requirements of the Exchange Act and the Securities Act and the rules and regulations thereunder, each of Parent, Acquisition Sub and the Company shall use reasonable efforts (1) to correct promptly any information provided by it for use in the Registration Statement or the Offer Documents to the extent such information shall have become false or misleading in any material respect and (2) to take all steps necessary to promptly cause the Registration Statement and the Offer Documents, as supplemented or amended to correct such information, to be filed with the SEC and to be disseminated to holders of shares of Company Common Stock. The Company shall promptly furnish to Parent and Acquisition Sub all information concerning the Acquired Corporations and the Company’s stockholders that may be required or reasonably requested in connection with any action contemplated by this Section 1.1(g). Parent shall use reasonable efforts to have the Registration Statement declared effective under the Securities Act as promptly as possible after its filing and to maintain its effectiveness for so long as shall be required for the issuance of Parent Common Stock pursuant to the Offer and the Merger. Following the time the Registration Statement is declared effective, Parent shall file the final prospectus included therein under Rule 424(b) under the Securities Act.

(h) If, between the date of this Agreement and the date on which any particular share of Company Common Stock is accepted for exchange or payment pursuant to the Offer, the outstanding shares of either Company Common Stock or Parent Common Stock are changed into a different number or class of shares by reason of any

stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Per Share Consideration shall be adjusted to the extent appropriate.

1.2 Company Actions.

(a) The Company consents to the Offer and represents and warrants to Parent and Acquisition Sub that the Company’s board of directors, at a meeting duly called and held, has by the unanimous vote of all directors of the Company (i) determined that this Agreement and the Contemplated Transactions, including the Offer and the Merger, are in the best interests of the Company’s stockholders, (ii) approved and adopted this Agreement and approved the Contemplated Transactions, including the Offer and the Merger, in accordance with the requirements of the Delaware General Corporation Law (“DGCL”), (iii) declared that this Agreement is advisable, (iv) resolved to recommend that stockholders of the Company accept the Offer and tender their shares of Company Common Stock pursuant to the Offer and adopt this Agreement (the recommendation of the Company’s board of directors that the stockholders of the Company accept the Offer and tender their shares of Company Common Stock pursuant to the Offer and adopt this Agreement being referred to as the “Company Board Recommendation”), and (v) to the extent necessary, adopted a resolution having the effect of causing the Company not to be subject to any restriction set forth in any state takeover law or similar Legal Requirement that might otherwise apply to the Stockholder Agreements, the Offer, the Merger or any of the other Contemplated Transactions. Subject to Section 1.2(b): (1) the Company consents to the inclusion of the Company Board Recommendation in the Offer Documents; and (2) the Company agrees that the Company Board Recommendation shall not be withdrawn or modified in a manner adverse to Parent or Acquisition Sub, and that no resolution of the board of directors of the Company or any committee thereof to withdraw or modify the Company Board Recommendation in a manner adverse to Parent or Acquisition Sub shall be adopted or proposed.

(b) Notwithstanding anything to the contrary contained in Section 1.2(a), the Company Board Recommendation may be withdrawn or modified in a manner adverse to Parent and Acquisition Sub at any time prior to the Acceptance Date if: (i) an unsolicited, bona fide written offer by a third party to purchase (whether by tender offer, merger, consolidation, business combination, reorganization or similar transaction) all of the outstanding shares of Company Common Stock (other than shares of Company Common Stock already held by such third party) is made to the Company and is not withdrawn; (ii) the Company’s board of directors determines in good faith (after taking into account the advice of an independent financial advisor of nationally recognized reputation) that such offer constitutes a Superior Offer; (iii) the Company’s board of directors determines in good faith, after having taken into account the advice of the Company’s outside legal counsel, that, in light of such Superior Offer, the withdrawal or modification of the Company Board Recommendation in a manner adverse to Parent or Acquisition Sub is required in order for the Company’s board of directors to comply with its fiduciary obligations to the Company’s stockholders under applicable Legal Requirements; and (iv) neither the Company nor any of its Representatives shall have breached any of the provisions set forth in Section 5.3 in any material respect.

(c) As promptly as practicable on the Offer Commencement Date, the Company shall file with the SEC and (following or contemporaneously with the dissemination of the Offer Documents to holders of shares of Company Common Stock to the extent required by applicable federal securities laws) disseminate to holders of shares of Company Common Stock a Solicitation/Recommendation Statement on Schedule 14D-9 (together with any amendments or supplements thereto, the “Schedule 14D-9”) that, subject only to Section 1.2(b), shall reflect the Company Board Recommendation. The Company shall use reasonable efforts to cause the Schedule 14D-9 to comply in all material respects with the applicable requirements of the Exchange Act and the rules and regulations thereunder and with all other applicable Legal Requirements. Parent and its counsel shall be given reasonable opportunity to review and comment on the Schedule 14D-9 (including any amendment or supplement thereto) prior to the filing thereof with the SEC. The Company shall promptly provide Parent and its counsel with a copy or a description of any comments received by the Company or its counsel from the SEC or its staff with

respect to the Schedule 14D-9, and the Company shall respond promptly to any such comments. To the extent required by the applicable requirements of the Exchange Act and the rules and regulations thereunder or by other Legal Requirements, (i) each of Parent, Acquisition Sub and the Company shall use reasonable efforts to promptly correct any information provided by it for use in the Schedule 14D-9 to the extent that such information shall have become false or misleading in any material respect, and (ii) the Company shall take all steps necessary to cause the Schedule 14D-9, as supplemented or amended to correct such information, to be filed with the SEC and to be disseminated to holders of shares of Company Common Stock. Parent and Acquisition Sub shall promptly furnish to the Company all information concerning Parent or Acquisition Sub that may be required or reasonably requested in connection with any action contemplated by this Section 1.2(c).

(d) The Company shall promptly provide to Parent (i) a list of the Company’s stockholders as well as mailing labels and any available listing or computer file containing the names and addresses of all record holders of shares of Company Common Stock and lists of securities positions of shares of Company Common Stock held in stock depositories, in each case accurate and complete as of the most recent practicable date, and (ii) such additional information (including updated lists of stockholders, mailing labels and lists of securities positions) and such other assistance as Parent may reasonably request in connection with the Offer or the Merger. Except as may be required by applicable Legal Requirements or legal process, and except as may be necessary to disseminate the Offer Documents to holders of shares of Company Common Stock to the extent required by applicable federal securities laws, Parent and Acquisition Sub shall hold in confidence, in accordance with the terms of the Company/Parent Confidentiality Agreement, any information contained in any such labels, listings and files provided by the Company to Parent that constitutes “Confidential Information” of the Company within the meaning of the Company/Parent Confidentiality Agreement.

1.3 Directors.

(a) Effective upon the Acceptance Date and from time to time thereafter, Parent shall be entitled to designate the number of directors, rounded up to the next whole number, on the Company’s board of directors determined by multiplying: (i) the total number of directors on the Company’s board of directors (giving effect to any increase in the size of the Company’s board of directors effected pursuant to this Section 1.3(a)); by (ii) a fraction having a numerator equal to the aggregate number of shares of Company Common Stock then beneficially owned by Parent or Acquisition Sub (including all shares of Company Common Stock accepted for exchange or payment pursuant to the Offer), and having a denominator equal to the total number of shares of Company Common Stock then issued and outstanding. The Company shall take all action necessary to cause Parent’s designees to be elected or appointed to the Company’s board of directors, including seeking and accepting resignations of incumbent directors and, if such resignations are not obtained, increasing the size of the Company’s board of directors. From and after the Acceptance Date, to the extent requested by Parent, the Company shall also use its best efforts to: (A) obtain and deliver to Parent the resignation of each individual who is an officer of any of the Acquired Corporations; and (B) cause individuals designated by Parent to constitute the number of members, rounded up to the next whole number, on (1) each committee of the Company’s board of directors and (2) the board of directors of each Subsidiary of the Company (and each committee thereof) that represents at least the same percentage as individuals designated by Parent represent on the board of directors of the Company. Notwithstanding the provisions of this Section 1.3, the Company shall use reasonable efforts to ensure that, at all times prior to the Effective Time, at least two of the members of the Company’s board of directors are individuals who were directors of the Company on the date of this Agreement (“Continuing Directors”); provided, however, that (1) if at any time prior to the Effective Time there shall be only one Continuing Director serving as a director of the Company for any reason, then the Company’s board of directors shall cause an individual selected by the remaining Continuing Director to be appointed to serve on the Company’s board of directors (and such individual shall be deemed to be a Continuing Director for all purposes under this Agreement), and (2) if at any time prior to the Effective Time no Continuing Directors remain on the Company’s board of directors, then the Company’s board of directors shall appoint two individuals who are not officers, employees or affiliates of the Company, Parent or Acquisition Sub to serve on the Company’s board of directors (and such individuals shall be deemed to be Continuing Directors for all purposes under this Agreement).

(b) The Company’s obligation to cause Parent’s designees to be elected or appointed to the Company’s board of directors shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 thereunder. The Company shall promptly take all actions, and shall include in the Schedule 14D-9 such information with respect to the Company and its officers and directors, as Section 14(f) of the Exchange Act and Rule 14f-1 thereunder require in order to fulfill its obligations under this Section 1.3, so long as Parent shall have provided to the Company the information with respect to Parent and its nominees, officers, directors and affiliates required by Section 14(f) of the Exchange Act and Rule 14f-1 thereunder. The provisions of this Section 1.3 are in addition to, and shall not limit, any right that Acquisition Sub, Parent or any affiliate of Acquisition Sub or Parent may have (with respect to the election of directors or otherwise) under applicable Legal Requirements as a holder or beneficial owner of shares of Company Common Stock.

(c) Following the election or appointment of Parent’s designees to the Company’s board of directors pursuant to Section 1.3(a) and until the Effective Time, the approval of a majority of the Continuing Directors shall be required to authorize any Adverse Action (as defined below). For purposes of this Section 1.3(c), “Adverse Action” shall mean any of the following actions of the Company, to the extent the action in question could reasonably be expected to affect adversely the holders of shares of Company Common Stock (other than Parent or Acquisition Sub): (i) any action by the Company with respect to any amendment or waiver of any term or condition of this Agreement, the Merger or the certificate of incorporation or bylaws of the Company; (ii) any termination of this Agreement or the Merger by the Company; (iii) any extension by the Company of the time for the performance of any of the obligations or other acts of Parent or Acquisition Sub, or any waiver or assertion of any of the Company’s rights under this Agreement; or (iv) any other consent or action by the Company’s board of directors with respect to this Agreement or the Merger. The approval of any Adverse Action by a majority of the Continuing Directors shall constitute the valid authorization of the Company’s board of directors with respect to such Adverse Action, and no other action on the part of the Company or by any other director of the Company shall be required to authorize such Adverse Action.

1.4 Top-Up Option.

(a) The Company grants to Parent and Acquisition Sub an assignable and irrevocable option (the “Top-Up Option”) to purchase from the Company the number of newly-issued shares of Company Common Stock equal to the lesser of (i) the number of shares of Company Common Stock that, when added to the number of shares of Company Common Stock owned by Parent or Acquisition Sub at the time of exercise of the Top-Up Option, constitutes 91% of the number of shares of Company Common Stock that would be outstanding immediately after the issuance of all shares of Company Common Stock subject to the Top-Up Option or (ii) the aggregate number of shares of Company Common Stock that the Company is authorized to issue under its certificate of incorporation but that are not issued and outstanding (and are not subscribed for or otherwise committed to be issued) at the time of exercise of the Top-Up Option.

(b) The Top-Up Option may be exercised by Parent or Acquisition Sub, in whole or in part, at any time on or after the Acceptance Date, provided that the number of shares of Company Common Stock beneficially owned by Parent or Acquisition Sub immediately prior to the time of exercise of the Top-Up Option constitutes at least 70% of the number of shares of Company Common Stock then outstanding. Except as otherwise provided in Section 1.4(c), (i) if the All-Cash Election shall not have been made, the aggregate purchase price payable for the shares of Company Common Stock being purchased by Parent or Acquisition Sub pursuant to the Top-Up Option shall consist of a combination of a cash payment and shares of Parent Common Stock, and (ii) if the All-Cash Election shall have been made, the aggregate purchase price payable for the shares of Company Common Stock being purchased by Parent or Acquisition Sub pursuant to the Top-Up Option shall be payable in cash. Except as otherwise provided in Section 1.4(c), if the All-Cash Election shall not have been made, the aggregate amount of cash payable to the Company in respect of the shares of Company Common Stock being purchased by Parent or Acquisition Sub pursuant to the Top-Up Option shall be determined by multiplying the number of such shares of Company Common Stock by the Exchange Offer Cash Amount, and the aggregate number of shares of Parent Common Stock deliverable to the Company for the shares of Company Common Stock being purchased by

Parent or Acquisition Sub pursuant to the Top-Up Option shall be determined by multiplying the number of such shares of Company Common Stock by the Applicable Fraction, and rounding up to the next whole share. Except as otherwise provided in Section 1.4(c), if the All-Cash Election shall have been made, the aggregate amount of cash payable to the Company in respect of the shares of Company Common Stock being purchased by Parent or Acquisition Sub pursuant to the Top-Up Option shall be determined by multiplying the number of such shares of Company Common Stock by the All-Cash Dollar Amount.

(c) Notwithstanding anything to the contrary contained in Section 1.4(b), in lieu of paying cash (or paying cash and delivering shares of Parent Common Stock) to the Company as consideration for the shares of Company Common Stock being purchased pursuant to the Top-Up Option as described in Section 1.4(b), Parent or Acquisition Sub may (i) pay to the Company in cash the aggregate par value of such shares of Company Common Stock, and (ii) execute and deliver to the Company a promissory note having a principal amount equal to: (A) the amount determined by multiplying (1) the number of shares of Company Common Stock being purchased by Parent or Acquisition Sub pursuant to the Top-Up Option by (2) the All-Cash Dollar Amount (whether or not the All-Cash Election shall have been made); minus (B) the dollar amount of the cash payment made pursuant to clause “(i)” of this sentence. Any such promissory note shall bear interest at the rate of 3% per annum and shall mature on the first anniversary of the date of execution and delivery of such promissory note.

(d) In the event Parent or Acquisition Sub wishes to exercise the Top-Up Option, Parent or Acquisition Sub shall deliver to the Company a notice setting forth (i) the number of shares of Company Common Stock that Parent or Acquisition Sub intends to purchase pursuant to the Top-Up Option, (ii) the manner in which Parent or Acquisition Sub intends to pay the applicable exercise price and (iii) the place and time at which the closing of the purchase of such shares of Company Common Stock by Parent or Acquisition Sub is to take place. At the closing of the purchase of such shares of Company Common Stock, Parent or Acquisition Sub shall cause to be delivered to the Company the consideration required to be delivered in exchange for such shares, and the Company shall cause to be issued to Parent or Acquisition Sub a certificate representing such shares.

The Merger shall become effective at the time of the filing of the Certificate of Merger with the Secretary of State of the State of Delaware (the “Effective Time”).

2.4 Certificate of Incorporation and Bylaws; Directors and Officers. Unless otherwise determined by Parent prior to the Effective Time:

(a) the Certificate of Incorporation of the Surviving Corporation shall be amended in its entirety immediately after the Effective Time to conform to the Certificate of Incorporation of Acquisition Sub as in effect immediately prior to the Effective Time, except that the name of the Surviving Corporation shall be “Monolithic System Technology, Inc.”;

2.5 Conversion of Shares.

(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Acquisition Sub, the Company or any stockholder of the Company:

(i) any shares of Company Common Stock then held by the Company or any wholly owned Subsidiary of the Company (or held in the Company’s treasury) shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(ii) any shares of Company Common Stock then held by Parent, Acquisition Sub or any other wholly owned Subsidiary of Parent shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(iii) except as provided in clauses “(i)” and “(ii)” above and subject to Sections 2.5(b), 2.5(c), 2.5(d) and 2.7, each share of Company Common Stock then outstanding shall be converted into the right to receive (upon the proper surrender of the certificate representing such share) the Per Share Consideration; and

(iv) each share of the common stock, $0.01 par value per share, of Acquisition Sub then outstanding shall be converted into one share of common stock of the Surviving Corporation.

(b) If, between the date of this Agreement and the Effective Time, the outstanding shares of either Company Common Stock or Parent Common Stock are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Per Share Consideration shall be adjusted to the extent appropriate.

(c) If any share of Company Common Stock outstanding immediately prior to the Effective Time is unvested or is subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other agreement with the Company or under which the Company has any rights, then the Per Share Consideration deliverable with respect thereto pursuant to Section 2.5(a)(iii) will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition. The Company shall take all action that may be necessary to ensure that, from and after the Effective Time, Parent is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other agreement.

(d) No fractional shares of Parent Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued in connection with the Merger. Any holder of Company Common Stock who would otherwise be entitled to receive a fraction of a share of Parent Common Stock in the Merger (after aggregating all fractional shares of Parent Common Stock issuable to such holder in the Merger) shall, in lieu of such fraction of a share and upon surrender of such holder’s Stock Certificate(s) (as defined in Section 2.6(b)), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest,

determined by multiplying such fraction by the closing trading price of a share of Parent Common Stock as reported on the Nasdaq National Market on the trading day immediately before the date on which the Merger becomes effective.

2.6 Surrender of Certificates; Stock Transfer Books.

(a) Prior to the Effective Time, Parent shall designate a bank or trust company to act as exchange agent in the Merger (the “Exchange Agent”). As soon as practicable after the Effective Time, Parent shall deposit with the Exchange Agent (i) cash in an amount equal to the cash payable pursuant to Section 2.5(a)(iii), (ii) certificates representing any shares of Parent Common Stock issuable pursuant to Section 2.5(a)(iii) and (iii) cash sufficient to make any payments in lieu of fractional shares of Parent Common Stock in accordance with Section 2.5(d), in each case assuming no holder of Company Common Stock perfects appraisal rights under Section 262 of the DGCL. The cash amounts and any shares of Parent Common Stock so deposited with the Exchange Agent, together with any dividends or distributions received by the Exchange Agent with respect to such shares, are referred to collectively as the “Exchange Fund.” The cash in the Exchange Fund shall be invested by the Exchange Agent as directed by Parent in money market funds or similar short-term liquid investments.

(b) As soon as reasonably practicable after the Effective Time, Parent will instruct the Exchange Agent to mail to the Persons who, immediately prior to the Effective Time, were record holders of certificates representing shares of Company Common Stock (“Stock Certificates”) (i) a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify (including a provision confirming that delivery of Stock Certificates shall be effected, and risk of loss and title to Stock Certificates shall pass, only upon delivery of such Stock Certificates to the Exchange Agent), and (ii) instructions for use in effecting the surrender of Stock Certificates. Upon surrender of a Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent, (A) the holder of such Stock Certificate shall be entitled to receive in exchange therefor the consideration deliverable to such holder pursuant to Section 2.5(a)(iii) and any cash payment in lieu of a fractional share of Parent Common Stock in accordance with Section 2.5(d), and (B) the Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 2.6(b), each Stock Certificate shall be deemed, from and after the Effective Time, to represent solely the right to receive the Per Share Consideration for each share of Company Common Stock formerly evidenced by such Stock Certificate. If any Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition to the delivery of any consideration with respect thereto, require the owner of such lost, stolen or destroyed Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such sum as Parent may reasonably direct) as indemnity against any claim that may be made against the Exchange Agent, Parent or the Surviving Corporation with respect to such Stock Certificate.

(c) No dividends or other distributions declared or made with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Stock Certificate with respect to any shares of Parent Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Stock Certificate in accordance with this Section 2.6 (at which time such holder shall be entitled, subject to the effect of applicable escheat or similar laws, to receive all such dividends and distributions, without interest).

(d) Any portion of the Exchange Fund that remains undistributed to holders of Stock Certificates as of the date 180 days after the date on which the Merger becomes effective shall be delivered to Parent upon demand, and any holders of Stock Certificates who have not theretofore surrendered their Stock Certificates in accordance with this Section 2.6 shall thereafter look only to Parent for satisfaction of their claims for delivery of consideration in connection with the Merger. Neither Parent nor the Surviving Corporation shall be liable to any holder or former holder of Company Common Stock or to any other Person with respect to any cash amounts or shares of Parent Common Stock delivered to any public official pursuant to any applicable abandoned property law, escheat law or similar Legal Requirement.

(e) At the Effective Time, holders of Stock Certificates that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company, and the stock transfer books of the Company shall be closed with respect to all shares of Company Common Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Common Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid Stock Certificate is presented to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in this Section 2.6.

(f) Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable to any holder or former holder of Company Common Stock pursuant to this Agreement such amounts as Parent or the Surviving Corporation determines in good faith may be required to be deducted or withheld therefrom under the Code or any provision of state, local or foreign Tax law or under any other Legal Requirement. To the extent any such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(g) If any Stock Certificate has not been surrendered by the earlier of (i) the fifth anniversary of the date on which the Merger becomes effective or (ii) the date immediately prior to the date on which the consideration that such Stock Certificate represents the right to receive would otherwise escheat to or become the property of any Governmental Body, then such consideration shall, to the extent permitted by applicable Legal Requirements, become the property of the Surviving Corporation, free and clear of any claim or interest of any Person previously entitled thereto.

2.7 Appraisal Rights.

(a) Notwithstanding anything to the contrary contained in this Agreement, any share of Company Common Stock that, as of the Effective Time, is held by a holder who has, as of the Effective Time, preserved such holder’s appraisal rights under Section 262 of the DGCL with respect to such share shall not be converted into or represent the right to receive the Per Share Consideration in accordance with Section 2.5(a)(iii), and the holder of such share shall be entitled only to such rights as may be granted to such holder pursuant to Section 262 of the DGCL with respect to such share; provided, however, that if such appraisal rights shall not be perfected or the holder of such share shall otherwise lose such holder’s appraisal rights with respect to such share, then, as of the later of the Effective Time or the time of the failure to perfect such rights or the loss of such rights, such share shall automatically be converted into and shall represent only the right to receive (upon the surrender of the Stock Certificate representing such share) the Per Share Consideration in accordance with Section 2.5(a)(iii).

(b) The Company shall give Parent (i) prompt notice of (A) any written demand received by the Company prior to the Effective Time to require the Company to purchase shares of Company Common Stock pursuant to Section 262 of the DGCL and (B) any other demand, notice or instrument delivered to the Company prior to the Effective Time pursuant to the DGCL, and (ii) the opportunity to direct all negotiations and proceedings with respect to any such demand, notice or instrument. Without limiting the generality of the foregoing, the Company shall not make any payment or settlement offer prior to the Effective Time with respect to any such demand unless Parent shall have consented in writing to such payment or settlement offer.

2.8 Tax Consequences. For federal income tax purposes, assuming that the All-Cash Election is not made, the Offer, the Merger and the Second Merger together are intended to constitute a reorganization within the meaning of Section 368(a) of the Code. The parties to this Agreement hereby adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

2.9 Further Action. If, at any time after the Effective Time, any further action is determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full

right, title and possession of and to all rights and property of Acquisition Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Acquisition Sub, in the name of the Company and otherwise) to take such action.

(f) No Employee Plan provides (except at no cost to the Acquired Corporations), or reflects or represents any liability of any of the Acquired Corporations to provide, retiree life insurance, retiree health benefits or other retiree employee welfare benefits to any Person for any reason, except as may be required by COBRA or other applicable Legal Requirements. To the knowledge of the Company, other than commitments made that involve no future costs to any of the Acquired Corporations, no Acquired Corporation has ever represented, promised or contracted (whether in oral or written form) to any former or current employee, consultant or director (either individually or as a group) or any other Person that any such employee, consultant or director or other Person would be provided with retiree life insurance, retiree health benefits or other retiree employee welfare benefits, except to the extent required by applicable Legal Requirements.

(g) Part 3.17(g) of the Disclosure Schedule describes all obligations of the Acquired Corporations as of the date of this Agreement under any of the provisions of COBRA.

(h) Each of the Employee Plans has been operated and administered in all material respects in accordance with its terms and with applicable Legal Requirements, including, but not limited to ERISA, the Code, applicable U.S. and non-U.S. securities laws and regulations and applicable foreign Legal Requirements. The Acquired Corporations have performed all material obligations required to be performed by them under, are not in default

or violation of, and have no knowledge of any default or violation by any other party to, the material terms of any Employee Plan. Each Employee Plan intended to be qualified under Section 401(a) of the Code has obtained a favorable determination letter (or opinion letter, if applicable) as to its qualified status under the Code, and to the knowledge of the Company, there has been no event, condition or circumstance that would reasonably be expected to result in disqualification under the Code (or in the case of a Foreign Plan, the equivalent of disqualification under any applicable foreign Legal Requirement). There are no actions, suits or claims pending, or to the knowledge of the Company, threatened or reasonably anticipated (other than routine claims for benefits) against any Employee Plan or against the assets of any Employee Plan. To the knowledge of the Company, no breach of fiduciary duty under which any of the Acquired Corporations or one its fiduciaries could reasonably be expected to incur a material liability has occurred. Each Employee Plan (other than any Employee Plan to be terminated prior to the Effective Time in accordance with this Agreement) can be amended, terminated or otherwise discontinued after the Effective Time in accordance with its terms, without liability to any of the Acquired Corporations (other than ordinary administration expenses and liability for accrued and vested benefits). No Employee Plan is under audit, investigation or other Legal Proceeding by the Internal Revenue Service, Department of Labor, or any other Governmental Body, nor is any such audit, investigation or Legal Proceeding pending or, to the knowledge of the Company, threatened. No “prohibited transaction,” within the meaning of Section 4975 of the Code or Sections 406 and 407 of ERISA, and not otherwise exempt under Section 408 of ERISA, has occurred with respect to any Employee Plan. No mortgage, lien, pledge, charge, security interest or encumbrance of any kind in respect of any Employee Plan imposed under the Code, ERISA or any foreign Legal Requirement exists. All contributions, premiums and expenses to or in respect of each Employee Plan have been paid in full or, to the extent not yet due, have been adequately accrued on the appropriate Acquired Corporation’s financial statements.

(i) None of the Acquired Corporations has incurred or reasonably expects to incur, either directly or indirectly (including as a result of an indemnification obligation), any material liability under Title I or IV of ERISA or the penalty, excise tax or joint and several liability provisions of the Code or any foreign Legal Requirement relating to employee benefit plans (including Section 406, 409, 502(i), 502(l), 4069 or 4212(c) of ERISA, or Section 4971, 4975 or 4976 of the Code), or under any agreement, instrument or Legal Requirement pursuant to or under which any of the Acquired Corporations or any Employee Plan has agreed to indemnify or is required to indemnify any Person against liability incurred under, or for a violation or failure to satisfy the requirements of, any such agreement, instrument or Legal Requirement, and to the knowledge of the Company, no event, transaction or condition has occurred, exists or is expected to occur which could result in any such material liability to any of the Acquired Corporations or, after the Closing, to Parent.

(j) Neither the execution, delivery or performance of this Agreement, nor the consummation of the Offer or the Merger or any of the other Contemplated Transactions (either alone or in combination with another event, whether contingent or otherwise) will (i) result in any bonus, severance or other payment or obligation to any current or former employee, consultant or director of any of the Acquired Corporations (whether or not under any Employee Plan); (ii) materially increase the benefits payable or provided to, or result in a forgiveness of indebtedness for any such employee, consultant or director; (iii) accelerate the vesting, funding or time of payment of any compensation, equity award or other similar benefit; (iv) result in any “parachute payment” under Section 280G of the Code (whether or not such payment is considered to be reasonable compensation for services rendered); or (v) cause any compensation to fail to be deductible under Section 162(m) of the Code or any other provision of the Code or any similar foreign Legal Requirement. Without limiting the generality of the foregoing (and except as set forth in Part 3.17(j) of the Disclosure Schedule), the consummation of the Offer or the Merger will not result in the acceleration of vesting of any unvested Company Options.

(k) The fair market value of the assets of each funded Foreign Plan, the liability of each insurer for any Foreign Plan funded through insurance or the book reserve established for any Foreign Plan, together with any accrued contributions, is sufficient to procure or provide in full for the accrued benefit obligations with respect to all current and former participants in such Foreign Plan according to the actuarial assumptions and valuations most recently used to determine employer contributions to and obligations under such Foreign Plan. Neither the

execution of this Agreement nor the consummation of the transactions contemplated hereby shall cause any the assets or insurance obligations to be less than the benefit obligations under such Employee Plan or Foreign Plan.

(l) Except as set forth in Part 3.17(l) of the Disclosure Schedule, none of the Acquired Corporations maintains any plan, agreement or arrangement, formal or informal, that provides material benefits in the nature of severance or has outstanding any liabilities with respect to material severance benefits.

(n) Except for the Company Option Plans, the ESPP and as set forth in Part 3.17(q) of the Disclosure Schedule, none of the Acquired Corporations maintains any plan, program or arrangement or is a party to any contract that provides any material benefits or provides for material payments to any Person in, based on or measured by the value of any equity security of, or interest in, the Acquired Corporations.

(q) With respect to each state workers’ compensation arrangement that is funded wholly or partially through an insurance policy or public or private fund, all premiums required to have been paid to date under such insurance policy or fund have been paid, all premiums required to be paid under the insurance policy or fund through the Closing Date will have been paid on or before the Closing Date and, as of the Closing Date, there will be no material liability of any the Acquired Corporations under any such insurance policy, fund or ancillary agreement with respect to such insurance policy in the nature of a retroactive rate adjustment, loss sharing arrangement or other actual or contingent material liability arising wholly or partially out of events occurring prior to the Closing Date.

(r) Part 3.17(r) of the Disclosure Schedule contains a list of all employees of each of the Acquired Corporations as of the date of this Agreement, and correctly reflects, in all material respects, their wage or salary, any other compensation payable to them (including compensation payable pursuant to bonus, deferred compensation or commission arrangements), their dates of employment and their positions.

During the three years prior to the date of this Agreement none of the Acquired Corporations has had any strike, slowdown, work stoppage, lockout, job action, or threat thereof, or question concerning representation, by or with respect to any of its employees. All of the employees of the Acquired Corporations are “at will” employees.

(d) The Company shall timely exercise in full any right or option it may have to repurchase shares of its capital stock which is or becomes exercisable during the Pre-Closing Period from any current or former employee, consultant, officer, member of the board of directors or other Person upon termination of such Person’s service to any of the Acquired Corporations; provided, however, that the Company shall use reasonable efforts to notify Parent in writing at least 10 days in advance of any such repurchase and, notwithstanding the above, shall only exercise any such repurchase right to the extent directed by Parent in writing.

5.3 No Solicitation.

(a) The Company shall not directly or indirectly, and shall not authorize or permit any of the other Acquired Corporations or any Representative of any of the Acquired Corporations directly or indirectly to, (i) solicit, initiate, encourage, induce or facilitate the making, submission or announcement of any Acquisition Proposal or Acquisition Inquiry or take any action that could reasonably be expected to lead to an Acquisition Proposal, (ii) furnish any information regarding any of the Acquired Corporations to any Person in connection with or in response to an Acquisition Proposal or Acquisition Inquiry, (iii) engage in discussions or negotiations with any Person with respect to any Acquisition Proposal or Acquisition Inquiry, (iv) approve, endorse or recommend any Acquisition Proposal or (v) enter into any letter of intent or similar document or any Contract contemplating or otherwise relating to any Acquisition Transaction; provided, however, that prior to the Acceptance Date, this Section 5.3(a) shall not prohibit the Company from furnishing nonpublic information regarding the Acquired Corporations to, or entering into discussions with, any Person in response to a Superior Offer that is submitted to the Company by such Person (and not withdrawn) if (1) neither the Company nor any Representative of any of the Acquired Corporations shall have breached any of the provisions set forth in this Section 5.3 in any material respect, (2) the board of directors of the Company determines in good faith, after having taken into account the advice of the Company’s outside legal counsel, that such action is required in order for the board of directors of the Company to comply with its fiduciary obligations to the Company’s stockholders under applicable law, (3) at least two business days prior to furnishing any such nonpublic information to, or entering into discussions with, such Person, the Company gives Parent written notice of the identity of such Person and of the Company’s intention to furnish nonpublic information to, or enter into discussions with, such Person, and the Company receives from such Person an executed confidentiality agreement containing limitations on the use and disclosure of all nonpublic written and oral information furnished to such Person by or on behalf of the Company no less favorable to the Company than the provisions of the Company/Parent Confidentiality Agreement, and (4) at least two business days prior to furnishing any such nonpublic information to such Person, the Company furnishes such nonpublic information to Parent (to the extent such nonpublic information has not been previously furnished by the Company to Parent). Without limiting the generality of the foregoing, the Company acknowledges and agrees that, in the event any Representative of any of the Acquired Corporations (whether or not such Representative is purporting to act on behalf of any of the Acquired Corporations) takes any action that, if taken by the Company, would constitute a breach of this Section 5.3 by the Company, the taking of such action by such Representative shall be deemed to constitute a breach of this Section 5.3 by the Company for purposes of this Agreement.

(b) If the Company or any of its Representatives receives an Acquisition Proposal or Acquisition Inquiry or any request for non-public information at any time during the Pre-Closing Period, then the Company shall promptly (and in no event later than 24 hours after receipt of such Acquisition Proposal, Acquisition Inquiry or request) advise Parent orally and in writing of such Acquisition Proposal, Acquisition Inquiry or request (including the identity of the Person making or submitting such Acquisition Proposal, Acquisition Inquiry or request, and the terms thereof). The Company shall keep Parent fully informed with respect to the status of any such Acquisition Proposal, Acquisition Inquiry or request and any modification or proposed modification thereto.

(c) The Company shall immediately cease and cause to be terminated any existing discussions with any Person that relate to any Acquisition Proposal or Acquisition Inquiry.

The Company also shall promptly request each Person that has executed a confidentiality agreement in connection with its consideration of a possible Acquisition Transaction or equity investment to return to the Acquired Corporations all confidential information heretofore furnished to such Person by or on behalf of any of the Acquired Corporations.

Section 6. ADDITIONAL COVENANTS OF THE PARTIES

6.1 Stockholder Approval; Proxy Statement.

(a) If the adoption of this Agreement by the Company’s stockholders is required by applicable Legal Requirements in order to consummate the Merger, the Company shall, as promptly as practicable following the later of the Acceptance Date or the expiration of any subsequent offering period provided in accordance with Rule 14d-11 under the Exchange Act, take all action necessary under applicable Legal Requirements to call, give notice of and hold a meeting of the holders of Company Common Stock to vote on the adoption of this Agreement (the “Company Stockholders’ Meeting”).

The Company shall respond promptly to any comments received from the SEC or its staff with respect to the Proxy Statement, and shall correct promptly any information in the Proxy Statement if and to the extent that such information shall have become false or misleading in any material respect. If at any time prior to the Company Stockholders’ Meeting there shall occur any event that should be set forth in an amendment or supplement to the Post-Effective Amendment or to the Proxy Statement, or the Post-Effective Amendment or the prospectus included therein is amended by Parent to correct any information therein, the Company shall (1) with respect to the Post-Effective Amendment and the prospectus included therein, cooperate with Parent in filing such amendment or supplement with the SEC and transmitting such supplement or amendment to the Company’s stockholders, and (2) with respect to the Proxy Statement, promptly prepare such an amendment or supplement and, after obtaining the consent of Parent to such amendment or supplement, promptly transmit such amendment or supplement to the Company’s stockholders.

(c) Prior to the Effective Time, Parent shall use reasonable efforts to obtain all material regulatory approvals needed to ensure that any Parent Common Stock to be issued in the Offer and the Merger will be registered or qualified under the securities law of every jurisdiction of the United States in which any registered holder of

Company Common Stock has an address of record; provided, however, that Parent shall not be required (i) to qualify to do business as a foreign corporation in any jurisdiction in which it is not now qualified or (ii) to file a general consent to service of process in any jurisdiction.

(d) Notwithstanding anything to the contrary contained in this Agreement, if Acquisition Sub shall own, by virtue of the Offer or otherwise, at least 90% of the outstanding shares of Company Common Stock, the parties shall take all actions necessary and appropriate to cause the merger of Acquisition Sub into the Company to become effective as soon as practicable without a stockholders’ meeting in accordance with Section 253 of the DGCL.

(e) Parent agrees to cause all shares of Company Common Stock owned by Parent, Acquisition Sub or any other subsidiary of Parent to be voted in favor of the adoption of the Agreement at the Company Stockholders’ Meeting.

Without limiting the generality of the foregoing, the Company and Parent shall, promptly after the date of this Agreement, prepare and file the notification and report forms required to be filed under the HSR Act and any notification or other document required to be filed under any applicable foreign antitrust or competition-related Legal Requirement in connection with the Offer, the Merger or the other Contemplated Transactions and the Stockholder Agreements.

At the request of Parent, the Company shall divest, sell, dispose of, hold separate or take any other action with respect to any of the businesses, product lines or assets of the Acquired Corporations, provided that any such action is conditioned upon the consummation of the Offer or the Merger.

6.3 Stock Options and ESPP.

(a) At the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time, whether or not vested and whether or not the exercise price of such Company Option is in excess of the value of the Per Share Consideration, shall be assumed by Parent in accordance with the terms (as in effect as of the date of this Agreement) of the stock option plan under which such Company Option was issued and the terms of the stock option agreement by which such Company Option is evidenced; provided, however, that each Company Option that is outstanding and unexercised immediately prior to the Effective Time under the 1996 Plan shall be assumed by Parent in accordance with this Section 6.3(a) only with the consent of the holder of such Company Option, and in the absence of such consent, such Company Option (if not exercised prior to the Effective Time) shall not be accelerated and shall terminate in accordance with the terms of the 1996 Plan. All rights with respect to Company Common Stock under Company Options assumed by Parent shall thereupon be converted into rights with respect to Parent Common Stock. Accordingly, from and after the Effective Time, (i) each Company Option assumed by Parent may be exercised solely for shares of Parent Common Stock, (ii) the number of shares of Parent Common Stock subject to each Company Option assumed by Parent shall be determined by multiplying the number of shares of Company Common Stock that were subject to such Company Option immediately prior to the Effective Time by the Conversion Ratio (as defined below), and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock, (iii) the per share exercise price for the Parent Common Stock issuable upon exercise of each Company Option assumed by Parent shall be determined by dividing the per share exercise price of Company Common Stock subject to such Company Option, as in effect immediately prior to the Effective Time, by the Conversion Ratio, and rounding the resulting exercise price up to the nearest whole cent, and (iv) any restriction on the exercise of any Company

Option assumed by Parent shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Company Option shall otherwise remain unchanged; provided, however, that (A) each Company Option assumed by Parent in accordance with this Section 6.3(a) shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction subsequent to the Effective Time, and (B) Parent’s board of directors or a committee thereof shall succeed to the authority and responsibility of the Company’s board of directors or any committee thereof with respect to each Company Option assumed by Parent. Parent shall use reasonable efforts to cause any Company Options that qualified as “incentive stock options” as defined in Section 422 of the Code prior to the Effective Time to continue to so qualify after the Effective Time, subject to the terms of the Company Option Plans and to the extent permitted under the Code; provided, however, that Parent shall not be required to seek the approval of its stockholders for the Company Options assumed by Parent or the Company Option Plans even if such approval is required to qualify the Company Options that were incentive stock options prior to the Effective Time as incentive stock options after the Effective Time. For purposes of this Section 6.3(a), “Conversion Ratio” shall mean the fraction having a numerator equal to the All-Cash Dollar Amount (whether or not the All-Cash Election shall have been made) and having a denominator equal to the Parent Average Stock Price; provided, however, that if, between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock or Parent Common Stock are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Conversion Ratio shall be adjusted to the extent appropriate.

(b) Following the Effective Time, Parent shall send to each holder of a Company Option assumed by Parent a written notice setting forth (x) the number of shares of Parent Common Stock subject to such assumed Company Option, and (y) the exercise price per share of Parent Common Stock issuable upon exercise of such assumed Company Option. Parent shall file with the SEC, no later than 15 days after the Effective Time, a registration statement on Form S-8 relating to the shares of Parent Common Stock issuable with respect to the Company Options assumed by Parent in accordance with Section 6.3(a). Parent shall use reasonable efforts to maintain the effectiveness of such registration statement for so long as any of the assumed Company Options shall remain outstanding.

(c) Notwithstanding anything to the contrary contained in this Section 6.3, in lieu of assuming an outstanding Company Option in accordance with Section 6.3(a), Parent may, at its election, cause such outstanding Company Option to be replaced by issuing a reasonably equivalent replacement stock option in substitution therefor.

(d) At the Effective Time, Parent shall assume the Company Option Plans. Under the Company Option Plans, Parent shall be able to grant stock awards, to the extent permissible under applicable Legal Requirements, using the share reserves of the Company Option Plans as of the Effective Time (including any shares returned to such share reserves as a result of the termination of Company Options that are assumed by Parent pursuant to Section 6.3(a)), except that (i) stock covered by such awards shall be shares of Parent Common Stock, (ii) all references in the Company Option Plans to a number of shares of Company Common Stock shall be deemed amended to refer instead to a number of shares of Parent Common Stock determined by multiplying the number of referenced shares of Company Common Stock by the Conversion Ratio, and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock, and (iii) Parent’s board of directors or a committee thereof shall succeed to the authority and responsibility of the Company’s board of directors or any committee thereof with respect to the administration of the Company Option Plans.

(e) Prior to the Effective Time, the Company shall take all action that may be necessary (under the Company Option Plans and otherwise) to effectuate the provisions of this Section 6.3 and to ensure that, from and after the Effective Time, holders of Company Options have no rights with respect thereto other than those specifically provided in this Section 6.3.

(f) The Company shall take such action as is necessary to (i) cause the exercise (as of the last business day prior to the date on which the Merger becomes effective) of each outstanding purchase right under the ESPP, and make any pro-rata adjustments as may be necessary to reflect the shortened offering period but otherwise treating such shortened offering period as a fully effective and completed offering period for all purposes under the ESPP, and (ii) provide that no further purchase period shall commence under the ESPP; provided, however, that such exercise and cessation of further purchase periods shall be conditioned upon the consummation of the Merger. On such new exercise date, the Company shall apply the funds credited as of such date under the ESPP within each participant’s payroll withholding account to the purchase of whole shares of Company Common Stock in accordance with the terms of the ESPP. At the Effective Time, a holder of a share of Company Common Stock received under the ESPP shall, by virtue of the Merger and without any action on the part of such holder, be entitled to receive the Per Share Consideration with respect thereto upon the surrender of the Stock Certificate representing such share as provided in Section 2.6. Immediately prior to and effective as of the Effective Time (and subject to the consummation of the Merger), the Company shall terminate the ESPP.

6.4 Employee Benefits.

(a) Parent agrees that (a) all employees of the Acquired Corporations who continue employment with Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation after the Effective Time (“Continuing Employees”) shall, subject to any necessary transition period and subject to any applicable plan provisions, contractual requirements or Legal Requirements, be eligible to participate in Parent’s health, vacation and 401(k) plans, to substantially the same extent as similarly situated employees of Parent, and (b) for purposes of determining a Continuing Employee’s eligibility to participate in such plans, such Continuing Employee shall receive credit under such plans for his or her years of service with the Acquired Corporations prior to the Effective Time. Parent shall use reasonable efforts to (i) cause to be waived any pre-existing condition limitations and eligibility waiting periods under any group health plan of Parent with respect to Continuing Employees and their eligible dependents, and (ii) cause each Continuing Employee to be given credit toward applicable deductibles and annual out-of-pocket limits under any group health plan of Parent for all amounts paid by such Continuing Employee for the plan year that includes the Effective Time under any similar group health plan of the Company in which such Continuing Employee was participating immediately prior to the Effective Time. Nothing in this Section 6.4(a) or elsewhere in this Agreement shall be construed to create a right in any employee of any of the Acquired Corporations to employment with Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation, and the employment of each Continuing Employee shall be “at will” employment. Except for Indemnified Persons (as defined in Section 6.5) to the extent of their respective rights pursuant to Section 6.5, no current or former employee, consultant or director of any of the Acquired Corporations, and no Continuing Employee, shall be deemed to be a third party beneficiary of this Agreement.

(b) The Company shall not take (or cause to be taken) any action to terminate any employee benefit plan sponsored by any of the Acquired Corporations (or in which any of the Acquired Corporations participates) that contains a cash or deferred arrangement intended to qualify under Section 401(k) of the Code; provided, however, that if otherwise directed in writing by Parent prior to the Effective Time, the Company shall take (or cause to be taken) all actions reasonably determined by Parent to be necessary or appropriate to terminate, effective immediately prior to the Effective Time, any such employee benefit plan.

6.5 Indemnification of Officers and Directors.

(a) All rights to indemnification by the Company existing in favor of those Persons who are directors and officers of the Company as of the date of this Agreement (the “Indemnified Persons”) for their acts and omissions as directors and officers occurring prior to the Effective Time, as provided in the Company’s bylaws (as in effect as of the date of this Agreement) and as provided in the indemnification agreements between the Company and said Indemnified Persons (as in effect as of the date of this Agreement) in the forms disclosed by the Company to Parent prior to the date of this Agreement, shall survive the Merger and shall continue in full force and effect (to the fullest extent such rights to indemnification are available under and consistent with Delaware law) for a period of six years from the Effective Time.

(b) From the Effective Time until the sixth anniversary of the Effective Time, the Surviving Corporation shall maintain in effect, for the benefit of the Indemnified Persons with respect to their acts and omissions as directors and officers occurring prior to the Effective Time, the existing policy of directors’ and officers’ liability insurance maintained by the Company as of the date of this Agreement in the form disclosed by the Company to Parent prior to the date of this Agreement (the “Existing D&O Policy”), to the extent that directors’ and officers’ liability insurance coverage is available on commercially reasonable terms; provided, however, that (i) the Surviving Corporation may substitute for the Existing D&O Policy a policy or policies of comparable coverage, and (ii) the Surviving Corporation shall not be required to pay annual premiums for the Existing D&O Policy (or for any substitute policies) in excess of the lesser of (A) $1,000,000 or (B) an amount equal to 125% of the annual premium paid in 2003 for the Existing D&O Policy (the lesser of such amounts being referred to herein as the “Maximum Premium”). In the event any future annual premiums for the Existing D&O Policy (or any substitute policies) exceed the Maximum Premium in the aggregate, the Surviving Corporation shall be entitled to reduce the amount of coverage of the Existing D&O Policy (or any substitute policies) to the amount of coverage that can be obtained for a premium equal to the Maximum Premium.

(c) Parent shall cause the Surviving Corporation to fulfill its obligations under Sections 6.5(a) and 6.5(b) above. Parent will not permit the Surviving Corporation (or the surviving corporation in the Second Merger) to merge or consolidate with any other Person unless the resulting or surviving entity assumes (by operation of law or otherwise) the obligations imposed by this Section 6.5.

6.6 Additional Agreements.

(a) Subject to Section 6.6(b), Parent and the Company shall use reasonable efforts to take, or cause to be taken, all actions necessary to consummate the Offer and the Merger and make effective the other Contemplated Transactions and the Stockholder Agreements. Without limiting the generality of the foregoing, but subject to Section 6.6(b), each party to this Agreement (i) shall cause to be made all filings (if any) and cause to be given all notices (if any) required to be made and given by such party or any Subsidiary of such Party in connection with the Offer and the Merger and the other Contemplated Transactions and the Stockholder Agreements, (ii) shall use reasonable efforts to cause to be obtained each Consent (if any) required to be obtained (pursuant to any applicable Legal Requirement or Contract, or otherwise) by such party in connection with the Offer and the Merger and each of the other Contemplated Transactions and the Stockholder Agreements, and (iii) shall use reasonable efforts to lift any restraint, injunction or other legal bar to the Offer, the Merger or any of the other Contemplated Transactions or any of the Stockholder Agreements. The Company shall promptly deliver to Parent a copy of each such filing made, each such notice given and each such Consent obtained by the Company during the Pre-Closing Period.

(b) Notwithstanding anything to the contrary contained in this Agreement, neither Parent nor Acquisition Sub shall have any obligation under this Agreement: (i) to dispose of or transfer or cause any of its Subsidiaries to dispose of or transfer any assets, or to commit to cause any of the Acquired Corporations to dispose of any assets; (ii) to discontinue or cause any of its Subsidiaries to discontinue offering any product or service, or to commit to cause any of the Acquired Corporations to discontinue offering any product or service; (iii) to license or otherwise make available, or cause any of its Subsidiaries to license or otherwise make available, to any Person, any technology, software or other Intellectual Property or Intellectual Property Rights, or to commit to cause any of the Acquired Corporations to license or otherwise make available to any Person any technology, software or other Intellectual Property or Intellectual Property Rights; (iv) to hold separate or cause any of its Subsidiaries to hold separate any assets or operations (either before or after the Closing Date), or to commit to cause any of the Acquired Corporations to hold separate any assets or operations; (v) to make or cause any of its Subsidiaries to make any commitment (to any Governmental Body or otherwise) regarding its future operations or the future operations of any of the Acquired Corporations; or (vi) to contest any Legal Proceeding commenced by any Governmental Body relating to the Offer, the Merger or any of the other Contemplated Transactions or any of the Stockholder Agreements if Parent determines in good faith that the costs and other consequences of contesting such Legal Proceeding would make it inadvisable for Parent or Acquisition Sub to contest such Legal Proceeding.

6.7 Disclosure. Parent and the Company shall consult with each other before issuing any press release or otherwise making any public statement with respect to the Offer, the Merger or any of the other Contemplated Transactions or any of the Stockholder Agreements. Without limiting the generality of the foregoing, the Company shall not, and shall not permit any of its Subsidiaries or any Representative of any of the Acquired Corporations to, make any disclosure to employees of any of the Acquired Corporations, to the public or otherwise regarding the Offer, the Merger or any of the other Contemplated Transactions or any of the Stockholder Agreements unless (a) Parent shall have approved such disclosure or (b) the Company shall have been advised in writing by its outside legal counsel that such disclosure is required by applicable Legal Requirements and shall have provided Parent with reasonable advance notice of the Company’s intention to make such disclosure and the content of such disclosure.

6.8 Letter of the Company’s Accountants. Unless the All-Cash Election shall have been made, the Company shall use reasonable efforts to cause to be delivered to Parent a letter of Ernst & Young LLP, dated no more than two business days before the date on which the Registration Statement becomes effective (and reasonably satisfactory in form and substance to Parent), that is customary in scope and substance for letters delivered by independent public accountants in connection with registration statements similar to the Registration Statement.

6.9 Listing. Unless the All-Cash Election shall have been made, Parent shall use reasonable efforts to cause the shares of Parent Common Stock being issued in the Offer to be approved for listing (subject to notice of issuance) on The Nasdaq National Market on or prior to the Acceptance Date, and Parent shall cause the shares of Parent Common Stock being issued in the Merger to be approved for listing (subject to notice of issuance) on The Nasdaq National Market at or prior to the Effective Time.

6.10 Section 16 Matters. Prior to the Effective Time, the Company shall take such reasonable steps as are required to cause the disposition of Company Common Stock and Company Options in connection with the Merger by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company to be exempt from Section 16(b) of the Exchange Act pursuant to Rule 16b-3 under the Exchange Act. If the Company delivers the Section 16 Information (as defined below) to Parent at least 30 days prior to the Effective Time, then, prior to the Effective Time, Parent shall take such reasonable steps as are required to cause the acquisition of options to purchase shares of Parent Common Stock in connection with the Merger by each individual who, immediately after the Effective Time, will become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Parent to be exempt from Section 16(b) of the Exchange Act pursuant to Rule 16b-3 under the Exchange Act. For purposes of this Section 6.10, “Section 16 Information” shall mean, for each individual who, immediately after the Effective Time, will become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Parent, the number of shares of Company Common Stock subject to Company Options held by such individual that are expected to be converted into options to purchase shares of Parent Common Stock in connection with the Merger.

6.11 Resignation of Officers and Directors. The Company shall use reasonable efforts to obtain and deliver to Parent at the Closing (effective as of the Effective Time) the resignation of each officer and director of each of the Acquired Corporations (other than those designees of Parent elected or appointed to the board of directors of each of the Acquired Corporations pursuant to Section 1.3).

6.12 Interim Operations of Acquisition Sub. During the Pre-Closing Period, Acquisition Sub shall not engage in any activities of any nature except as provided in or contemplated by this Agreement.

6.13 Obligations of Acquisition Sub. Parent shall take all action necessary to cause Acquisition Sub to perform its obligations under this Agreement.

6.14 Tax Opinions. At or prior to the time of the filing of the Registration Statement, unless the All-Cash Election shall have been made, Parent, Acquisition Sub and the Company shall execute and deliver to Cooley

Godward LLP and to ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ LLP tax representation letters in customary form. Parent, Acquisition Sub and the Company shall each confirm to such counsel the accuracy and completeness of such tax representation letters as of the Acceptance Date. Following delivery of such tax representation letters, each of Parent and the Company shall use reasonable efforts to cause ▇▇▇▇▇▇ Godward LLP and ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ LLP, respectively, to deliver to it a tax opinion satisfying the requirements of Item 601 of Regulation S-K under the Securities Act. In rendering such opinions, each of such counsel shall be entitled to rely on the tax representation letters described in this Section 6.14.

6.15 Second Merger. Unless the All-Cash Election shall have been made, as soon as practicable after the Effective Time, but not later than 15 days after the Effective Time, Parent shall adopt and shall cause the Surviving Corporation to adopt an agreement and plan of merger and reorganization with respect to the Second Merger pursuant to which, not later than 15 days after the Effective Time, the Surviving Corporation shall be merged with and into Parent or, at Parent’s election, a wholly owned subsidiary of Parent, with Parent or such subsidiary being the surviving corporation of the Second Merger. Notwithstanding the foregoing, Parent and the Surviving Corporation shall not cause the Second Merger to be effected unless Parent and the Company have received, prior to the consummation of the Second Merger, an opinion of ▇▇▇▇▇▇ Godward LLP reasonably satisfactory to Parent (the “Closing Tax Opinion”) that the Offer, the Merger and the Second Merger together should constitute a reorganization under the provisions of Section 368(a) of the Code. The Closing Tax Opinion may rely on the tax representation letters described in Section 6.14 and on typical assumptions. It is intended that, unless the All-Cash Election shall have been made, and absent a change in facts or law subsequent to the date of this Agreement that prevents Parent from obtaining the Closing Tax Opinion, (i) the Second Merger shall occur, (ii) the acquisition of shares of Company Common Stock pursuant to the Offer, followed by the Merger and the Second Merger, together would qualify as a reorganization under the provisions of Section 368(a) of the Code, and (iii) this Agreement would constitute a “plan of reorganization” within the meaning of section 1.368-2(g) of the regulations under the Code. In the event that ▇▇▇▇▇▇ Godward LLP is unable to render the Closing Tax Opinion, the condition in this Section 6.15 relating to the delivery of the Closing Tax Opinion to Parent shall be deemed satisfied if ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ LLP renders the Closing Tax Opinion to Parent.

Section 7. CONDITIONS PRECEDENT TO THE MERGER

The respective obligations of the parties to effect the Merger are subject to the satisfaction, at or prior to the Closing, of each of the following conditions:

7.1 Stockholder Approval. If required by applicable Legal Requirements in order to consummate the Merger, this Agreement shall have been duly adopted by the Required Company Stockholder Vote.

7.2 No Restraints. No temporary restraining order, preliminary or permanent injunction or other order preventing the consummation of the Merger shall have been issued by any court of competent jurisdiction and remain in effect, and there shall not be any Legal Requirement enacted or deemed applicable to the Merger that makes consummation of the Merger illegal.

7.3 Effectiveness of Registration Statement. Unless the All-Cash Election shall have been made, the Registration Statement and the Post-Effective Amendment shall have become effective in accordance with the provisions of the Securities Act, and no stop order shall have been issued by the SEC and be outstanding, and no proceeding for that purpose shall have been initiated by the SEC and be outstanding or be threatened by the SEC, with respect to the Registration Statement or the Post-Effective Amendment.

7.4 Listing. Unless the All-Cash Election shall have been made, the shares of Parent Common Stock being issued in the Offer and in the Merger shall have been approved for listing (subject to notice of issuance) on The Nasdaq National Market.

7.5 Consummation of Offer. Acquisition Sub shall have accepted for exchange or payment all shares of Company Common Stock validly tendered (and not withdrawn) pursuant to the Offer.

Section 8. TERMINATION

8.1 Termination. This Agreement may be terminated:

(a) by mutual written consent of Parent and the Company at any time prior to the Effective Time;

(b) by either Parent or the Company at any time prior to the Effective Time if a court of competent jurisdiction or other Governmental Body shall have issued a final and nonappealable order, decree or ruling, or shall have taken any other action, having the effect of (i) permanently restraining, enjoining or otherwise prohibiting (A) the acquisition or acceptance for exchange or payment of, or the delivery of consideration in exchange for, any shares of Company Common Stock pursuant to the Offer or (B) the Merger, (ii) making illegal the acquisition of, or the delivery of consideration in exchange for, shares of Company Common Stock pursuant to the Offer, or (iii) making the consummation of the Merger illegal; provided, however, that a party shall not be permitted to terminate this Agreement pursuant to this Section 8.1(b) if the issuance of such order, decree or ruling or the taking of such action is attributable to the failure of such party to perform in any material respect any covenant in this Agreement required to be performed by such party at or prior to the Effective Time;

(c) by either Parent or the Company at any time prior to the Acceptance Date if the Offer shall have expired without Acquisition Sub having accepted shares of Company Common Stock for exchange or payment pursuant to the Offer; provided, however, that a party shall not be permitted to terminate this Agreement pursuant to this Section 8.1(c) if (i) the failure of Acquisition Sub to accept shares of Company Common Stock for exchange or payment pursuant to the Offer is attributable to the failure of an Offer Condition to be satisfied, and (ii) the failure of such Offer Condition to be satisfied is attributable to a failure, on the part of the party seeking to terminate this Agreement, to perform in any material respect any covenant in this Agreement required to be performed by such party on or prior to the Acceptance Date;

(d) by either Parent or the Company at any time after July 31, 2004 and prior to the Acceptance Date if the Acceptance Date shall not have occurred on or prior to July 31, 2004; provided, however, that a party shall not be permitted to terminate this Agreement pursuant to this Section 8.1(d) if (i) the failure of the Acceptance Date to occur on or prior to July 31, 2004 is attributable to the failure of an Offer Condition to be satisfied, and (ii) the failure of such Offer Condition to be satisfied is attributable to a failure on the part of such party to perform in any material respect any covenant in this Agreement required to be performed by such party on or prior to the Acceptance Date;

(e) by Parent at any time prior to the Acceptance Date if a Triggering Event shall have occurred;

(f) by the Company at any time prior to the Acceptance Date, in order to accept a Superior Offer and enter into the Specified Definitive Acquisition Agreement (as defined below) relating to such Superior Offer, if (i) such Superior Offer shall not have resulted from any breach of any of the provisions of Section 5.3 in any material respect or from any action taken by the Company or any of its Representatives with the intent of circumventing any of the provisions set forth in Section 5.3, (ii) the board of directors of the Company, after satisfying all of the requirements set forth in Section 1.2(b) and otherwise causing the Company to comply in all material respects with the provisions of this Agreement, shall have authorized the Company to enter into a binding, written, definitive acquisition agreement providing for the consummation of the transaction contemplated by such Superior Offer (the “Specified Definitive Acquisition Agreement”), (iii) the Company shall have delivered to Parent a written notice (that includes a copy of the Specified Definitive Acquisition Agreement as an attachment) containing the Company’s representation and warranty that the Specified Definitive Acquisition Agreement has been duly executed and delivered to the Company by the other party thereto, that the board of directors of the Company has authorized the execution and delivery of the Specified Definitive Acquisition Agreement on behalf of the Company and that the Company will enter into the Specified Definitive Acquisition Agreement immediately upon termination of this Agreement pursuant to this Section 8.1(f), (iv) a period of at least five business days shall have elapsed since the receipt by Parent of such notice, and the Company shall have made its Representatives fully available during such period for the purpose of engaging in

negotiations with Parent regarding a possible amendment of the Offer or a possible alternative transaction, (v) any written proposal by Parent to amend the Offer or enter into an alternative transaction shall have been considered by the board of directors of the Company in good faith, and the Company’s board of directors shall have determined in good faith (after having taken into account the advice of the Company’s outside legal counsel and the advice of an independent financial advisor of nationally recognized reputation) that the terms of the proposed amended Offer (or other alternative transaction) are not as favorable to the Company’s stockholders, from a financial point of view, as the terms of the transaction contemplated by the Specified Definitive Acquisition Agreement, and (vi) the Company shall have paid to Parent the fee required to be paid to Parent pursuant to Section 8.3(c);

(g) by Parent at any time prior to the Acceptance Date if: (i) any of the Company’s representations and warranties contained in this Agreement shall be inaccurate as of the date of this Agreement or shall have become inaccurate as of a date subsequent to the date of this Agreement (as if made on such subsequent date), in either case such that the condition set forth in clause “(a)” or clause “(b)” of Exhibit B would not be satisfied (it being understood that, for purposes of determining the accuracy of such representations and warranties as of the date of this Agreement or as of any subsequent date, (A) all “Material Adverse Effect” qualifications and other materiality qualifications contained in such representations and warranties shall be disregarded and (B) any update of or modification to the Disclosure Schedule made or purported to have been made on or after the date of this Agreement shall be disregarded); or (ii) any of the Company’s covenants contained in this Agreement shall have been breached such that the condition set forth in clause “(c)” of Exhibit B would not be satisfied; provided, however, that (x) if an inaccuracy in any of the Company’s representations and warranties as of a date subsequent to the date of this Agreement or a breach of a covenant by the Company is curable by the Company within 15 days after the date of the occurrence of such inaccuracy or breach and the Company is continuing to exercise reasonable efforts to cure such inaccuracy or breach, then Parent may not terminate this Agreement under this Section 8.1(g) on account of such inaccuracy or breach (1) during the 15-day period commencing on the date on which the Company receives notice of such inaccuracy or breach or (2) after such 15-day period if such inaccuracy or breach shall have been fully cured in a manner that does not result in a breach of any covenant of the Company, and (y) Parent shall not be permitted to terminate this Agreement pursuant to this Section 8.1(g) unless Parent shall have paid any fee required to be paid by Parent to the Company pursuant to Section 8.3(d);

(h) by the Company at any time prior to the Acceptance Date if: (i) Parent’s representations and warranties contained in this Agreement shall be materially inaccurate as of the date of this Agreement, or shall have become materially inaccurate as of a date subsequent to the date of this Agreement (as if made on such subsequent date), and the inaccuracy in such representations and warranties has a material adverse effect on Parent’s or Acquisition Sub’s ability to purchase and pay for shares of Company Common Stock validly tendered pursuant to the Offer or on the Company’s ability to satisfy the Offer Conditions (including the Minimum Condition); or (ii) Parent shall have committed a material breach of its covenants contained in this Agreement and such breach has a material adverse effect on Parent’s or Acquisition Sub’s ability to purchase and pay for the shares of Company Common Stock validly tendered pursuant to the Offer or on the Company’s ability to satisfy the Offer Conditions (including the Minimum Condition); provided, however, that if an inaccuracy in any of Parent’s representations and warranties or a breach of a covenant by Parent is curable by Parent within 15 days after the date of the occurrence of such inaccuracy or breach and Parent is continuing to exercise reasonable efforts to cure such inaccuracy or breach, then the Company may not terminate this Agreement under this Section 8.1(h) on account of such inaccuracy or breach (1) during the 15-day period commencing on the date on which Parent receives notice of such inaccuracy or breach or (2) after such 15-day period if such inaccuracy or breach shall have been cured in a manner that does not result in a breach of any covenant of Parent; or

(i) by Parent at any time prior to the Acceptance Date if (i) a Company Material Adverse Effect shall have occurred or (ii) any event shall have occurred or circumstance shall have arisen that, in combination with any other events or circumstances, could reasonably be expected to have or result in a Company Material Adverse Effect; provided, however, that Parent shall not be permitted to terminate this Agreement pursuant to this Section 8.1(i) unless Parent shall have paid any fee required to be paid by Parent to the Company pursuant to Section 8.3(d).

8.2 Effect of Termination. In the event of the termination of this Agreement as provided in Section 8.1, this Agreement shall be of no further force or effect; provided, however, that (i) this Section 8.2, Section 8.3 and Section 9 (and the Company/Parent Confidentiality Agreement) shall survive the termination of this Agreement and shall remain in full force and effect, (ii) except as provided in Section 8.3(d), the termination of this Agreement shall not relieve any party from any liability for any willful breach of this Agreement and (iii) no termination of this Agreement shall in any way affect any of the parties’ rights or obligations with respect to any shares of Company Common Stock accepted for exchange or payment pursuant to the Offer prior to such termination.

8.3 Expenses; Termination Fees.

(a) Except as set forth in this Section 8.3, all fees and expenses incurred in connection with this Agreement and the Contemplated Transactions shall be paid by the party incurring such expenses, whether or not the Offer or the Merger is consummated; provided, however, that if (i) this Agreement is terminated by Parent pursuant to Section 8.1(c) or Section 8.1(d), (ii) immediately prior to the termination of this Agreement the number of shares of Company Common Stock validly tendered (and not withdrawn) pursuant to the Offer shall not have satisfied the Minimum Condition, and (iii) all other Offer Conditions are then satisfied, then, within five business days after receiving appropriate documentation therefor, Parent shall make a nonrefundable cash payment to the Company in an amount equal to the lesser of (A) the aggregate amount of all reasonable and documented out-of-pocket fees and expenses actually paid by the Company to its legal and financial advisors and accountants (at applicable standard or discounted rates) for services provided by them that relate exclusively to the Contemplated Transactions or (B) $750,000.

(b) If (i) this Agreement is terminated by Parent or the Company pursuant to Section 8.1(c) or Section 8.1(d), (ii) at or prior to the time of the termination of this Agreement the commencement, submission or making of an Acquisition Proposal shall have been disclosed or announced, (iii) immediately prior to the termination of this Agreement the number of shares of Company Common Stock validly tendered (and not withdrawn) pursuant to the Offer shall not have satisfied the Minimum Condition, and (iv) within one year after the date of termination of this Agreement, an Acquisition Transaction is consummated or a definitive agreement contemplating an Acquisition Transaction is executed, then the Company shall pay to Parent, in cash at the earlier of the time such Acquisition Transaction is consummated or the time such definitive agreement is executed, a nonrefundable fee in the amount of $10,000,000 (it being understood that, for the sole purpose of this clause “(iv),” the references to “15%” in the definition of “Acquisition Transaction” shall be deemed instead to refer to “40%”).

(c) If this Agreement is terminated by Parent pursuant to Section 8.1(e) or by the Company pursuant to Section 8.1(f), then the Company shall pay to Parent, in cash at the time specified in the next sentence, a nonrefundable fee in the amount of $10,000,000. In the case of termination of this Agreement by Parent pursuant to Section 8.1(e), the fee referred to in the preceding sentence shall be paid by the Company within two business days after such termination; and in the case of termination of this Agreement by the Company pursuant to Section 8.1(f), the fee referred to in the preceding sentence shall be paid by the Company at or prior to the time of such termination.

(d) Notwithstanding anything to the contrary contained in this Agreement, if Parent wishes to terminate this Agreement and (1) determines in good faith that it may validly terminate this Agreement pursuant to Section 8.1(g), (2) determines in good faith that it may validly terminate this Agreement pursuant to Section 8.1(i), or (3) determines in good faith (x) that Parent was entitled not to accept shares of Company Common Stock for exchange or payment pursuant to the Offer, (y) that, as of the expiration date of the Offer, all Offer Conditions were satisfied or had been waived except for one or more of the Offer Conditions set forth in clauses “(a),” “(b)” and “(d)” of Exhibit B, and (z) that Parent may validly terminate this Agreement pursuant to Section 8.1(c) or Section 8.1(d), then (i) Parent shall deliver to the Company a notice of termination specifying that Parent has made the good faith determination set forth in clause “(1),” clause “(2)” or clause “(3)” of this sentence, (ii)

Parent shall pay to the Company, at or immediately following the delivery by Parent to the Company of such notice of termination, a nonrefundable fee in the amount of $10,000,000, (iii) upon the payment by Parent of such nonrefundable fee, this Agreement shall immediately terminate and be of no further force or effect, and (iv) following the payment by Parent of such nonrefundable fee, no party to this Agreement shall have any liability of any nature to any other party to this Agreement under or relating to this Agreement (whether for any inaccuracy in any representation or warranty, for any prior breach of this Agreement, for the termination of this Agreement or otherwise), and no party to this Agreement shall be entitled to contest or otherwise challenge the termination of this Agreement or the basis therefor; provided, however, that clause “(iv)” of this sentence shall not prevent the Company from bringing a contest or challenge that asserts that a determination set forth in clause “(1),” clause “(2)” or clause “(3)” of this sentence was not made by Parent in good faith.

(e) If either the Company or Parent fails to pay when due any amount payable under this Section 8.3, then (i) such party shall reimburse the other party for all costs and expenses (including fees and disbursements of counsel) incurred in connection with the collection of such overdue amount and the enforcement by the other party of its rights under this Section 8.3, and (ii) such party shall pay to the other party interest on such overdue amount (for the period commencing as of the date such overdue amount was originally required to be paid and ending on the date such overdue amount is actually paid to such party in full) at a rate per annum equal to the “prime rate” (as announced by Bank of America or any successor thereto) in effect on the date such overdue amount was originally required to be paid.

Section 9. MISCELLANEOUS PROVISIONS

9.2 Waiver. No failure on the part of any party to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No party shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

9.3 No Survival of Representations and Warranties. None of the representations and warranties contained in this Agreement or in any certificate delivered pursuant to this Agreement shall survive the Merger. Subject to the last sentence of Section 9.8, this Section 9.3 shall not limit any covenant of the parties which by its terms contemplates performance after the Effective Time.

9.4 Entire Agreement; Counterparts. This Agreement and the other agreements referred to in this Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof and thereof; provided, however, that the Company/Parent Confidentiality Agreement shall not be superseded and shall remain in full force and effect. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument.

9.5 Applicable Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.
