AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) is made and entered into as of July 23, 2002 by and among Synopsys, Inc., a Delaware corporation (“Parent”), Ferrite Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), and inSilicon Corporation, a Delaware corporation (the “Company”). Unless otherwise defined herein, all capitalized terms used in this Agreement shall have the respective meanings ascribed thereto in Article IX hereof.

RECITALS

A. It is proposed that Merger Sub shall, as promptly as practicable, commence a tender offer (the “Offer”) to acquire all of the outstanding shares (the “Company Shares”) of Company Common Stock, at a price of Four Dollars and Five Cents ($4.05) per Company Share, net to the holder thereof in cash (such amount, or any different amount per Company Share that may be paid pursuant to the Offer, being hereinafter referred to as the “Offer Price”), all upon the terms and subject to the conditions set forth herein.

B. It is also proposed that, following the execution and delivery of this Agreement, all necessary action will be taken as a result of which, effective immediately prior to the Appointment Time, no shares of Company Exchangeable Preferred Stock will be issuable or outstanding (the “Canadian Exchange Transaction”).

C. It is also proposed that, following the consummation of the Offer, Merger Sub will merge with and into the Company and each Company Share that is not tendered and accepted pursuant to the Offer will thereupon be cancelled and converted into the right to receive cash in an amount equal to the Offer Price, all upon the terms and subject to the conditions set forth herein.

D. Each of the Boards of Directors of Parent and Merger Sub, as well as the Company Board (based upon a recommendation of the Special Committee), has (i) determined that this Agreement is advisable, (ii) determined that this Agreement and the transactions contemplated hereby, including the Offer and the Merger, taken together, are at a price and on terms that are fair to and in the best interests of their respective stockholders, and (iii) approved this Agreement and the transactions contemplated hereby, including the Offer and the Merger, all upon the terms and subject to the conditions set forth herein.

E. Concurrently with the execution and delivery of this Agreement, as a condition and inducement to the willingness of Parent and Merger Sub to enter into this Agreement, each of the directors and executive officers of the Company, and the Company’s majority stockholder, Phoenix Technologies Ltd. (“Phoenix Technologies”), in their respective capacities as stockholders of the Company, have entered into Tender and Voting Agreements with Parent substantially in the form attached hereto as Exhibit A and Exhibit B, respectively (each, a “Tender and Voting Agreement” and collectively, the “Tender and Voting Agreements”).

F. Concurrently with the execution and delivery of this Agreement, as a condition and inducement to the willingness of Parent and Merger Sub to enter into this Agreement, the Company’s majority stockholder has entered into a Termination and Amendment of Intercompany Agreements Agreement with Parent, in the form attached hereto as Exhibit C (the “Termination and Amendment Agreement”).

NOW, THEREFORE, in consideration of the foregoing premises and the representations, warranties, covenants and agreements set forth herein, as well as other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged and accepted, and intending to be legally bound hereby, Parent, Merger Sub and the Company hereby agree as follows:

ARTICLE I

THE OFFER

1.1 The Offer.

(a) Terms of Offer; Conditions to Offer. Provided that (i) this Agreement shall not have been terminated pursuant to Article VIII hereof, (ii) none of the events set forth in clauses (v)(d), (v)(f) or (v)(g) of Annex A hereto shall have occurred and be continuing, and (iii) a Triggering Event shall not have occurred, as promptly as practicable after the date hereof (but in no event more than ten (10) business days thereafter), Merger Sub shall (and Parent shall cause Merger Sub to) commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer to purchase all of the Company Shares at a price per Company Share, subject to the terms of Section 1.1(b) hereof, equal to the Offer Price. The obligation of Merger Sub to accept for payment and to pay for any Company Shares tendered (and the obligation of Parent to cause Merger Sub to accept for payment and to pay for any Company Shares tendered) shall be subject only to (i) the condition (the “Minimum Condition”) that, prior to the then scheduled expiration date of the Offer (as it may be extended from time to time pursuant to Section 1.1(c) hereof), there be validly tendered in accordance with the terms of the Offer and not withdrawn a number of shares of Company Common Stock that, together with the Company Shares then owned by Parent and Merger Sub (if any), represents at least a majority of all then outstanding Company Shares, calculated on a fully-diluted basis (including, without limitation, all shares of Company Common Stock issued or issuable upon the redemption of all outstanding shares of Company Exchangeable Preferred Stock and the exercise of all then outstanding Company Options, other than Company Options with an exercise price that is greater than the Offer Price), and (ii) the other conditions set forth in Annex A hereto. Parent and Merger Sub expressly reserve the right to increase the Offer Price or to make any other changes in the terms and conditions of the Offer; provided, however, that unless otherwise provided by this Agreement or previously approved by the Company in writing, neither Parent nor Merger Sub may make any change to the terms and conditions of the Offer that (i) decreases the Offer Price, (ii) changes the form of consideration to be paid in the Offer, (iii) reduces the number of Company Shares to be purchased in the Offer, (iv) imposes conditions to the Offer in addition to the conditions to the Offer set forth in Annex A hereto, (v) amends the conditions to the Offer set forth in Annex A hereto so as to broaden the scope of such conditions to the Offer, (vi) extends the Offer except as provided in Section 1.1(c) hereof, (vii) amends or waives the Minimum Condition, or (viii) makes any other change to any of the terms and conditions of the Offer that is adverse to the holders of Company Shares in the reasonable and good faith judgment of the Company. The conditions to the Offer set forth in Annex A hereto are for the sole benefit of Parent and Merger Sub and may be waived by Parent and Merger Sub, in whole or in part, at any time and from time to time, in their sole discretion, other than the Minimum Condition, which may be waived by Parent and Merger Sub only with the prior written consent of the Company. The failure by Parent and Merger Sub at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right, and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.

(b) Adjustments to Offer Price. The Offer Price shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), extraordinary cash dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to Company Common Stock (other than the Canadian Exchange Transaction) occurring on or after the date hereof and prior to Merger Sub’s acceptance for payment of, and payment for, Company Shares pursuant to the Offer.

(c) Extension and Expiration of Offer. Subject to the terms and conditions of the Offer and this Agreement, the Offer shall expire at midnight, New York Time, on the date that is twenty (20) business days

(calculated in accordance with Section 14d-1(g)(3) under the Exchange Act) after the date the Offer is commenced (within the meaning of Rule 14d-2 under the Exchange Act); provided, however, that (i) Merger Sub shall extend the Offer for any period required by any rule, regulation, interpretation or position of the SEC or its staff, or of the Nasdaq Stock Market, Inc., that is applicable to the Offer, and (ii) in the event that any of the conditions to the Offer set forth on Annex A hereto are not satisfied or waived as of any then scheduled expiration date of the Offer, Merger Sub shall extend the Offer for successive extension periods of not more than ten (10) business days each, until such time as either (A) all of the conditions to the Offer are satisfied or waived, or (B) this Agreement is terminated pursuant to the terms of Article VIII hereof; provided, however, that notwithstanding the foregoing clauses (i) and (ii) of this Section 1.1(c), in no event shall Merger Sub be required to extend the Offer beyond the Initial Termination Date or the Extended Termination Date, as applicable; and provided further, that the foregoing clauses (i) and (ii) of this Section 1.1(c) shall not be deemed to impair, limit or otherwise restrict in any manner the right of Parent to terminate this Agreement pursuant to the terms of Article VIII hereof.

(d) Payment for Company Shares. Subject to the terms and conditions of the Offer and this Agreement, Merger Sub shall (and Parent shall cause Merger Sub to) accept for payment, and pay for, all Company Shares validly tendered and not withdrawn pursuant to the Offer, as promptly as practicable after the applicable expiration date of the Offer (as it may be extended in accordance with Section 1.1(c) hereof). The Offer Price payable in respect of each Company Share validly tendered and not withdrawn pursuant to the Offer shall be paid net to the holder thereof in cash, subject to reduction only for any applicable federal back-up withholding or other Taxes payable by such holder.

(e) Subsequent Offering Period. Merger Sub may (but shall not be required to), and the Offer Documents shall reserve the right to, extend the Offer for a subsequent offering period (within the meaning of Rule 14d-11 under the Exchange Act) of not less than three (3) nor more than twenty (20) business days immediately following the expiration of the Offer; provided, however, that in the event that more than eighty five percent (85%) of the then outstanding Company Shares have been validly tendered and not withdrawn pursuant to the Offer on the applicable expiration date of the Offer (as it may be extended in accordance with Section 1.1(c) hereof), Merger Sub shall extend the Offer for a subsequent offering period (within the meaning of Rule 14d-11 under the Exchange Act) of ten (10) business days immediately following the applicable expiration date of the Offer. Subject to the terms and conditions of the Offer and this Agreement, Merger Sub shall (and Parent shall cause Merger Sub to) accept for payment, and pay for, all Company Shares validly tendered and not withdrawn pursuant to the Offer as so extended by such subsequent offering period, as promptly as practicable after any such Company Shares are tendered during such subsequent offering period. The Offer Price payable in respect of each Company Share validly tendered and not withdrawn pursuant to the Offer, as so extended by such subsequent offering period, shall be paid net to the holder thereof in cash, subject to reduction only for any applicable federal back-up withholding or other Taxes payable by such holder.

(f) Schedule TO; Offer Documents. As soon as practicable on the date the Offer is commenced (within the meaning of Rule 14d-2 under the Exchange Act), Parent and Merger Sub shall (i) prepare and file with the SEC a Tender Offer Statement on Schedule TO (together with all amendments and supplements thereto, and including all exhibits thereto, the “Schedule TO”) with respect to the Offer, which shall contain as an exhibit or incorporate by reference an Offer to Purchase, or portions thereof (the “Offer to Purchase”), and forms of the letter of transmittal and summary advertisement, if any, in respect of the Offer (together with any supplements or amendments thereto, the “Offer Documents”), and (ii) cause the Offer Documents to be disseminated to all holders of Company Shares and (in compliance with applicable securities laws of the Province of Ontario, Canada) to all holders of Company Exchangeable Preferred Stock (collectively, the “Company Securityholders”). Subject to the provisions of Section 6.4 hereof, the Schedule TO and the Offer Documents may include a description of the determinations, approvals and recommendations of the Company Board (based upon a unanimous recommendation of the Special Committee) set forth in Section 1.2(a) hereof. The Company shall promptly furnish to Parent and Merger Sub in writing all information concerning the Company that may be required by applicable securities laws or reasonably requested by Parent and Merger Sub for inclusion in the

Schedule TO or the Offer Documents.

Parent and Merger Sub hereby agree that the Schedule TO and the Offer Documents, when filed with the SEC and on the date first published, sent or given to the Company’s stockholders, shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that no representation or warranty is made by Parent or Merger Sub with respect to information supplied by the Company in writing specifically for inclusion or incorporation by reference in the Schedule TO or the Offer Documents. The Company hereby agrees that the information provided by the Company in writing specifically for inclusion or incorporation by reference in the Schedule TO or the Offer Documents shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of Parent, Merger Sub and the Company shall promptly correct any information provided by it for use in the Schedule TO or the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect. Parent and Merger Sub shall take all steps necessary to cause the Schedule TO and the Offer Documents, as so corrected, to be filed with the SEC and the other Offer Documents, as so corrected, to be disseminated to the Company Securityholders, in each case as and to the extent required by applicable federal securities laws. Parent and Merger Sub shall provide the Company and its counsel a reasonable opportunity to review and comment on the Schedule TO and the Offer Documents prior to the filing thereof with the SEC. Parent and Merger Sub shall provide to the Company and its counsel any and all written comments that Parent, Merger Sub or their counsel may receive in writing from the SEC or its staff with respect to the Schedule TO and the Offer Documents promptly after receipt thereof, and Parent and Merger Sub shall provide the Company and its counsel a reasonable opportunity to participate in the formulation of any written response to any such written comments of the SEC or its staff.

(d) Rights of First Refusal. Solely in connection with the tender and purchase of Company Shares pursuant to the Offer and the consummation of the Merger, the Company hereby waives any and all rights of first refusal it may have with respect to Company Shares owned by, or issuable to, any Person, other than rights to repurchase unvested shares, if any, that may be held by Persons pursuant to the grant of restricted stock purchase rights or following exercise of employee stock options.

1.3 Company Boards of Directors and Committees; Section 14(f) of Exchange Act.

(a) Composition of Company Board. Effective upon the initial acceptance for payment by Merger Sub of Company Shares pursuant to the Offer (the “Appointment Time,” the use of which term herein shall not, unless the context otherwise requires, depend upon whether Parent shall exercise its rights under this Section 1.3(a)) and from time to time thereafter, subject to the penultimate sentence of this Section 1.3(a), Parent shall be entitled to designate up to such number of directors on the Company Board equal to the product (rounded up to the next whole number) obtained by multiplying (x) the number of directors on the Company Board (giving effect to any increase in the number of directors pursuant to this Section 1.3), and (y) a fraction, the numerator of which is the number of Company Shares held by Parent and Merger Sub (giving effect to the Company Shares purchased pursuant to the Offer), and the denominator of which is the total number of then outstanding Company Shares.

In the event that any Certificates shall have been lost, stolen or destroyed, the Payment Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable in respect thereof pursuant to Section 2.7 hereof; provided, however, that Parent may, in its discretion and as a condition precedent to the payment of such Merger Consideration, require the owners of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Payment Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

2.11 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Merger Sub, the directors and officers of the Company and Merger Sub shall take all such lawful and necessary action.

3.6 Compliance with Laws; Permits.

(a) Company Stockholders’ Meeting. If approval of the stockholders of the Company is required under Delaware Law in order to consummate the Merger other than pursuant to Section 253 of the DGCL, the Company shall establish a record date for, call, give notice of, convene and hold a meeting of the stockholders of the Company (the “Company Stockholders’ Meeting”) as promptly as practicable following the Appointment Time for the purpose of voting upon the adoption of this Agreement in accordance with Delaware Law. Nothing herein shall prevent the Company from postponing or adjourning the Company Stockholders’ Meeting if there are insufficient shares of the Company Common Stock necessary to conduct business at the Company Stockholders’ Meeting. Unless the Company Board shall have withheld, withdrawn, amended or modified its recommendation in accordance with the provisions of Section 6.4 hereof, the Company shall use all commercially reasonable efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement in accordance with Delaware Law, and shall take all other commercially reasonable action necessary or advisable to secure the Requisite Stockholder Vote at the Company Stockholders’ Meeting. Unless this Agreement is earlier terminated pursuant to Article VIII hereof, the Company shall establish a record date for, call, give notice of, convene and hold the Company Stockholders’ Meeting for the purpose of voting upon the adoption of this Agreement in accordance with Delaware Law whether or not the Company Board at any time subsequent to the date hereof shall determine that this Agreement is no longer advisable or recommends that the Company’s stockholders reject it. Notwithstanding anything to the contrary set forth in this Agreement, the Company’s obligation to establish a record date for, call, give notice of, convene and hold the Company Stockholders’ Meeting pursuant to this Section 6.2 shall not be limited to, or otherwise affected by, the commencement, disclosure, announcement or submission to the Company of any Acquisition Proposal.

Parent shall vote all of the shares of capital stock of Merger Sub beneficially owned by it, or sign a written consent in lieu of a meeting of the stockholders of Merger Sub, in favor of the adoption of this Agreement in accordance with Delaware Law.

(c) Short-Form Merger. Notwithstanding the provisions of this Section 6.2 or Section 6.3 hereof, in the event that Parent, Merger Sub or any other Subsidiary of Parent, shall acquire at least ninety percent (90%) of the issued and outstanding Company Shares pursuant to the Offer or otherwise, each of Parent, Merger Sub and the Company shall take all necessary and appropriate action to cause the Merger to become effective as soon as practicable after such acquisition, without a meeting of the stockholders of the Company, in accordance with Section 253 of the DGCL.

6.3 Proxy Statement; Recommendation of the Company Board.

(a) Proxy Statement. If approval of the Company’s stockholders is required by Delaware Law in order to consummate the Merger other than pursuant to Section 253 of the DGCL, as soon as practicable following the Appointment Time, the Company and Parent shall jointly prepare, and the Company shall file with the SEC, a proxy statement for use in connection with the solicitation of proxies from the Company’s stockholders in connection with the Merger and the Company Stockholders’ Meeting (the “Proxy Statement”). The Company and Parent, as the case may be, shall furnish all information concerning the Company or Parent as the other party hereto may reasonably request in connection with the preparation and filing with the SEC of the Proxy Statement. Subject to all applicable Legal Requirements, the Company shall use all commercially reasonable efforts to cause the Proxy Statement to be disseminated to the Company’s stockholders as promptly as practicable following the filing thereof with the SEC. No filing of, or amendment or supplement to, or correspondence with the SEC or its staff with respect to the Proxy Statement shall be made by the Company without providing Parent a reasonable opportunity to review and comment thereon. The Company shall advise Parent, promptly after it receives notice thereof, of any request by the SEC or its staff for an amendment or

revisions to the Proxy Statement, or comments thereon and responses thereto, or requests by the SEC or its staff for additional information in connection therewith. If at any time prior to the Company Stockholders’ Meeting, any information relating to the Company or Parent, or any of their respective directors, officers or affiliates, should be discovered by the Company or Parent which should be set forth in an amendment or supplement to the Proxy Statement so that the Proxy Statement would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other party or parties hereto, as the case may be, and an appropriate amendment or supplement to the Proxy Statement describing such information shall be promptly prepared and filed with the SEC and, to the extent required by applicable law, disseminated to the stockholders of the Company. The Company shall cause the Proxy Statement to comply as to form and substance in all material respects with the applicable requirements of the Exchange Act and the rules of the Nasdaq.

(b) Recommendation of Company Board. Subject to the provisions of Section 6.4 hereof, the Proxy Statement shall include a description of the determinations and approvals and the recommendation of the Company Board (other than with respect to the Offer) set forth in Section 1.2(a) hereof; provided, however, that the Company Board shall submit to the Company’s stockholders this Agreement for their adoption in accordance with Delaware Law, whether or not at any time subsequent to the date hereof the Company Board (based upon a recommendation of the Special Committee or otherwise) shall determine that it can no longer make the recommendation (other than with respect to the Offer) set forth in Section 1.2(a) hereof to the Company’s stockholders in respect of this Agreement.

6.4 Withdrawal of Recommendation by Company Board. Nothing in this Agreement shall prevent the Company Board (based upon a recommendation from the Special Committee) from (i) withholding, withdrawing, amending or modifying its recommendation that the holders of Company Shares accept the Offer and tender their Company Shares to Merger Sub pursuant to the Offer, and that the stockholders of the Company adopt this Agreement in accordance with Delaware Law, if (A) neither the Company nor any of its representatives shall have violated any of the provisions of Section 6.1 hereof and (B) the Company Board concludes in good faith (based upon a recommendation of the Special Committee following consultation by the Special Committee with its outside legal counsel), that the withholding, withdrawal, amendment or modification of such recommendation is required in order for the Company Board to comply with its fiduciary duties to the Company’s stockholders under Delaware Law, or (ii) approving or recommending that the holders of Company Shares approve an Acquisition Proposal that is not withdrawn, if (A) such Acquisition Proposal constitutes a Superior Proposal, (B) neither the Company nor any of its representatives shall have violated any of the provisions of Section 6.1 hereof, and (C) the Company Board concludes in good faith (based upon a recommendation of the Special Committee following consultation by the Special Committee with its outside legal counsel), that, in light of such Superior Proposal, the approval or recommendation of such Acquisition Transaction is required in order for the Company Board to comply with its fiduciary duties to the Company’s stockholders under Delaware Law; provided, however, that prior to taking any action described in the foregoing clauses (i) or (ii) of this Section 6.4, the Company Board shall have given Parent at least two (2) business days notice thereof and the opportunity to meet with the Company Board, the Special Committee and their respective outside legal counsel. Nothing contained in this Section 6.4 shall limit the Company’s obligation to call, fix a record date for, give notice of, convene and hold the Company Stockholders’ Meeting (regardless of whether the recommendation of the Company Board shall have been withheld, withdrawn, amended or modified). Nothing in this Agreement shall prohibit the Company Board (based upon a recommendation of the Special Committee) from (i) taking and disclosing to the Company’s stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act, (ii) complying with the provisions of Rule 14d-9 promulgated under the Exchange Act, and (iii) making any other disclosure required by applicable law, provided that, in each case, any statement(s) made by the Company Board (based upon a recommendation of the Special Committee or otherwise) pursuant to Rule 14e-2(a) under the Exchange Act or Rule 14d-9 under the Exchange Act shall be subject to the terms and conditions of this Agreement, including, without limitation, the provisions of Article VIII hereof.

Upon the terms and subject to the conditions set forth in this Agreement, each of Parent, Merger Sub and the Company shall use all commercially reasonable efforts to take, or cause to be taken, all reasonable actions, and to do, or cause to be done, and to assist and cooperate with the other party or parties hereto in doing, all things reasonably necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement (including the Offer and the Merger), including, without limitation, using commercially reasonable efforts to accomplish the following: (i) causing the conditions precedent set forth in Article VII hereof and on Annex A hereto to be satisfied or fulfilled, (ii) obtaining all necessary actions or non-actions, waivers, consents, approvals, orders and authorizations from Governmental Entities, making all necessary registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities, if any), and taking all commercially reasonable steps as may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Entity, (iii) contesting and defending any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby (including the Offer and the Merger), including, without limitation, seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed, and (iv) executing or delivering any additional instruments reasonably necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement; provided, however, that notwithstanding anything to the contrary set forth in this Agreement, nothing in this Agreement shall be deemed to require Parent or the Company or any Subsidiary or affiliate thereof to agree to any divestiture by itself or any of its affiliates of shares of capital stock or of any business, assets or property, or the imposition of any limitation on the ability of any of them to conduct their business or to own or exercise control of such assets, properties and stock.

(b) State Anti-Takeover Statutes. Without limiting the generality of the foregoing provisions of Section 6.8(a) hereof, in the event that any state anti-takeover or other similar statute or regulation is or becomes applicable to this Agreement or any of the transactions contemplated by this Agreement (including the Offer and

the Merger), the Company, at the direction of the Company Board (based upon a recommendation of the Special Committee), shall use all commercially reasonable efforts to ensure that the transactions contemplated by this Agreement (including the Offer and the Merger) may be consummated as promptly as practicable on the terms and subject to the conditions set forth in this Agreement, and otherwise to minimize the effect of such statute or regulation on this Agreement and the transactions contemplated hereby (including the Offer and the Merger).

At all times and from time to time during the period commencing with the execution and deliver of this Agreement and continuing until the Appointment Time, the Company shall give prompt notice to Parent upon becoming aware that any representation or warranty made by it in this Agreement has become untrue or inaccurate in any material respect, or of any failure of the Company to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement.

(a) In-the-Money Company Options. The Company shall take all action necessary to provide that, effective as of the Effective Time, by virtue of the Merger and without any action on the part of Parent, the Company or any holder of Company Options, each outstanding Company Option, whether or not vested, with an exercise price that is less than or equal to the Merger Consideration (each, an “In-the-Money Company Option”) shall be assumed by Parent. Each In-the-Money Company Option so assumed by Parent shall continue to have, and be subject to, the same terms and conditions of such In-the-Money Company Option immediately prior to the Effective Time (including, without limitation, any repurchase rights or vesting provisions), except that (i) each In-the-Money Company Option shall be exercisable (or will become exercisable in accordance with its terms) for that number of whole shares of Parent Common Stock equal to the product obtained by multiplying (x) the aggregate number of shares of Company Common Stock that were issuable upon exercise of such In-the-Money Company Option immediately prior to the Effective Time (not taking into account any restrictions on exercise or vesting), and (y) the quotient obtained by dividing (A) the Merger Consideration by (B) the average of the closing prices of one (1) share of Parent Common Stock, as quoted on the Nasdaq for the five consecutive (5) trading days immediately preceding the Closing Date (the “Exchange Ratio”), rounded down to the nearest whole number of shares of Parent Common Stock, and (ii) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed the In-the-Money Company Option (not taking into account any restrictions on exercise or vesting) shall be equal to the quotient obtained by dividing (x) the exercise price per share of such In-the-Money Company Option immediately prior to the Effective Time and (y) the Exchange Ratio, rounded up to the nearest whole cent. Parent shall comply with the terms of all such In-the-Money Company Options and use commercially efforts to ensure, to the extent required by, and subject to

the provisions of, the Company Option Plans and permitted under the Code that any In-the-Money Company Options that qualified as “incentive stock options” as defined in Section 422 of the Code prior to the Effective Time continue to so qualify after the Effective Time. Parent shall take all corporate actions necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery pursuant to the terms set forth in this Section 6.11(a). As soon as practicable, but in no case later than twenty (20) calendar days after the Effective Time, Parent shall issue to each person who holds an assumed In-the-Money Company Option a document evidencing the assumption of such Company Option by Parent pursuant to the terms of this Section 6.11(a).

(b) Out-of-the-Money Company Options. The Company shall take all action necessary to provide that, effective as of the Effective Time, by virtue of the Merger and without any action on the part of Parent, the Company or any holder of Company Options, each outstanding Company Option, whether or not vested, with an exercise price that is greater than the Merger Consideration (each, an “Out-of-the-Money Company Option”) shall become fully vested and exercisable, and, to the extent not exercised, shall terminate as of the Effective Time without the receipt of any consideration therefor to the holder of any such Out-of-the-Money Company Option.

(c) Company ESPP. The Company shall amend the Company ESPP, as necessary, to provide that prior to the Effective Time, outstanding purchase rights under the Company ESPP shall be exercised in accordance with the terms of the Company ESPP and each share of Company Common Stock purchased pursuant to such exercise shall by virtue of the Merger, and without any action on the part of the holder thereof, be converted into the right to receive cash in an amount equal to the Merger Consideration. The Company shall terminate the Company ESPP immediately following the aforesaid purchase of shares of the Company Common Stock thereunder.

(d) Form S-8. As soon as is reasonably practicable after the Effective Time (and in no event more than fifteen (15) business days thereafter), Parent shall file, if available for use by Parent, a registration statement on Form S-8 to register the shares of Parent Common Stock issuable upon the exercise of all Company Options assumed by Parent pursuant to the provisions of Section 6.11(a) hereof. Parent shall maintain the effectiveness of such registration statement (and maintain the current status of the prospectus contained therein) for so long as any of the assumed Company Options shall remain outstanding.

6.12 Employee Matters.

(a) Company 401(k) Plans. The Company shall terminate, effective as of the day immediately preceding the date the Company becomes a member of the same Controlled Group of Corporations (as defined in Section 414(b) of the Code) as Parent (the “401(k) Termination Date”), any and all 401(k) plans maintained by the Company or any of its Subsidiaries unless Parent shall provide notice to the Company that any such 401(k) plan(s) shall not be terminated pursuant to this Section 6.12(a). The Company shall provide Parent evidence that the 401(k) plan(s) of the Company and its Subsidiaries have been terminated pursuant to resolutions of the Company Board or the board of directors of its Subsidiaries, as applicable (the form and substance of such resolutions shall be subject to review and approval of Parent), effective as of the 401(k) Termination Date.

(b) Service Credit. From and after the Effective Time, Parent shall take commercially reasonable actions to allow employees of the Company who continue their employment with the Company or who become employees of Parent or any Subsidiary of Parent (the “Continuing Employees”) to participate in the benefit programs of Parent to the same extent as similarly situated employees of Parent as soon as practicable after the Effective Time. Without limiting the generality of the foregoing, to the extent permitted under applicable law, each Continuing Employee shall be given credit for all service with the Company or its Subsidiaries (or service credited by the Company or its Subsidiaries) under all employee benefit plans, programs, policies and arrangements maintained by Parent or the Surviving Corporation (other than sabbatical benefits, for which employees of the Company or its Subsidiaries will not receive any such past service credit) in which they participate or in which they become participants for purposes of eligibility, levels of benefits and vesting;

provided, however, that no such credit shall be provided in any circumstance that would result in duplicative benefits. From and after the Effective Time, Parent shall (or shall use commercially reasonable efforts to cause the Company to) (i) cause any pre-existing conditions or limitations and eligibility waiting periods (to the extent that such waiting periods would be applicable, taking into account service with the Company or its Subsidiaries) under any group health plans of Parent or its affiliates to be waived with respect to Continuing Employees and their eligible dependents, and (ii) give each Continuing Employee credit for the plan year in which the Effective Time occurs toward applicable deductibles and annual out of pocket limit for expenses incurred prior to the Effective Time for which payment has been made.

(c) Severance Agreements. The Company shall terminate any and all group severance, separation, deferred compensation or salary continuation plans, programs or arrangements maintained by the Company or any of its Subsidiaries, effective in each case as of the day immediately preceding the last day of the initial period of the Offer (not including any subsequent offer period provided by Parent pursuant to Rule 14d-11 of the Exchange Act). The Company shall provide Parent evidence that such plans have been terminated pursuant to resolutions of the Company Board or the board of directors of its Subsidiaries, as applicable (the form and substance of which resolutions shall be subject to review and approval of Parent).

6.13 Directors’ and Officers’ Indemnification.

(a) Indemnification Agreements; Charter Documents. From and after the Effective Time, Parent shall (and shall cause the Surviving Corporation to) fulfill and honor in all respects the obligations of the Company under any indemnification Contracts in effect immediately prior to the Effective Time between the Company and its current and former directors and officers (the “Company Indemnified Parties”), and any indemnification provisions set forth in the Company Charter Documents as in effect on the date hereof, in each case to the fullest extent permitted by applicable law. The Certificate of Incorporation and Bylaws of the Surviving Corporation shall contain provisions with respect to exculpation and indemnification of directors and officers that are at least as favorable to the Company Indemnified Parties as those contained in the Company Charter Documents as in effect on the date hereof, which provisions will not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of individuals who were directors or officers of the Company, unless such modification is required by applicable law. Each of Parent, Merger Sub and the Company acknowledge and hereby agree that each of the Company Indemnified Parties is intended to be a third party beneficiary of the terms of this Section 6.13(a).

(b) Directors’ and Officers’ Insurance. For a period of six (6) years following the Effective Time, Parent shall cause the Surviving Corporation to maintain in effect, if available, directors’ and officers’ liability insurance covering those persons who are covered by the Company’s directors’ and officers’ liability insurance policy as of the date hereof or as of the Effective Time (the “Covered Persons”) in an amount and on terms no less favorable, when taken as a whole, to those applicable to the directors and officers of the Company as of the date hereof; provided, however, that in no event shall Parent or the Surviving Corporation be required to expend an annual premium for such coverage in excess of two hundred percent (200%) of the annual premium currently paid by the Company under its directors’ and officer’s liability insurance policy in effect as of the date hereof, and if the cost for such coverage is in excess of such amount, the Surviving Corporation shall only be required to maintain such coverage as is available for such amount (it being understood and hereby agreed that if Parent or the Surviving Corporation shall elect to satisfy its obligations under this Section 6.13(b) by purchasing a multi-year “tail” or similar policy, the annual premium limitation set forth in this Section 6.13(b) shall be measured by dividing the total premium for such multi-year “tail” or similar policy by the number of years covered thereby and comparing such quotient to two hundred percent (200%) of the annual premium currently paid by the Company under its directors’ and officers’ liability insurance policy in effect as of the date hereof). Each of Parent, Merger Sub and the Company acknowledge and hereby agree that each of the Covered Persons is intended to be a third party beneficiary of the terms of this Section 6.13(b).

(c) Successors and Assigns. In the event the Company or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the

continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to any Person in a single transaction or a series of related transactions, then, and in each such case, Parent shall either guaranty the indemnification obligations referred to in this Section 6.13 or shall make or cause to be made proper provision so that the successors and assigns of the Company or the Surviving Corporation, as the case may be, shall assume the indemnification obligations set forth in this Section 6.13 for the benefit of the Company Indemnified Parties.

6.14 Regulatory Filings. As soon as may be reasonably practicable following the execution and delivery of this Agreement, each of Parent and the Company shall file with the FTC and the Antitrust Division of the DOJ a Notification and Report Form relating to this Agreement and the transactions contemplated hereby (including the Offer and the Merger) as required by the HSR Act, as well as comparable pre-merger notification filings, forms and submissions with any foreign Governmental Entity that may be required by the merger notification or control laws and regulations of any applicable foreign jurisdiction, in each case as the parties may deem necessary and/or appropriate. Each of Parent and the Company shall promptly (i) cooperate and coordinate with the other in the making of such filings, (ii) supply the other with any information that may be required in order to effectuate such filings, and (iii) supply any additional information that reasonably may be required by the FTC, the DOJ or the competition or merger control authorities of any other jurisdiction and that the parties hereto reasonably deem necessary and/or appropriate; provided, however, that Parent shall not be required to agree to any divestiture by Parent or the Company (or any of Parent’s Subsidiaries or affiliates) of shares of capital stock or of any business, assets or property of Parent or its Subsidiaries or affiliates (or of the Company or its affiliates), or the imposition of any material limitation (in the reasonable good faith opinion of Parent) on the ability of any of them to conduct their businesses or to own or exercise control of their respective assets, properties and stock.
