(iii) Unregistered Transferees. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, then the Merger Consideration may be issued and/or paid in accordance with this Section 2.3(c) to a person other than the person in whose name the Company Certificate so surrendered is registered if (A) such Company Certificate is properly endorsed or otherwise in proper form for transfer and (B) the person requesting such payment (1) pays any transfer or other Taxes required by reason of the transfer or (2) establishes to the reasonable satisfaction of Parent and the Exchange Agent that such Taxes have been paid or are not applicable.

(iv) No Other Rights. Until surrendered in accordance with this Section 2.3(c), each Company Certificate and Book Entry Share shall be deemed, from and after the Effective Time, to represent only the right to receive the aggregate Merger Consideration payable in respect of the shares represented by such Company Certificate or Book Entry Share. The Merger Consideration issued or paid upon the surrender of any Company Certificate or Book Entry Share will be deemed to have been issued or paid in full satisfaction of all rights pertaining to that (A) Company Certificate and the shares of Company Common Stock formerly represented by it or (B) Book Entry Share.

(v) 102 Common Stock. Notwithstanding the foregoing, any ADSs issuable pursuant to Section 2.1 (and any cash paid with respect to fractional ADSs pursuant to Section 2.3(f)) in respect of Company Common Stock acquired upon the exercise of Company Stock Options granted under Section 102 of the Israeli Income Tax Ordinance [New Version], 1961, as amended, and all rules and regulations promulgated thereunder (“ITO”), shall be delivered by the Exchange Agent to the Trustee promptly after the Effective Time in accordance with the Israeli Option Tax Ruling, if obtained, and held in trust by the Trustee pursuant to the applicable provisions of Section 102 and the Israeli Options Tax Ruling, if obtained. Such cash and ADSs shall be released by the Trustee in accordance with the terms and conditions of Section 102 of the ITO, the Option Tax Ruling, if obtained, the trust documents governing the trust held by the Trustee, and the other terms and conditions otherwise set forth herein with respect to stockholders of the Company.

(d) Distributions with Respect to Unexchanged Shares.

Subject to applicable Laws, following the proper surrender of any such Company Certificate or Book Entry Share, there shall be

AGREEMENT AND PLAN OF MERGER (continued)

issued or paid to such holder of ADSs issuable in exchange therefor, without interest, (x) at the time of such surrender, the dividends or other distributions payable (if any) with respect to such ADSs or the underlying Parent Ordinary Shares that have a record date after the Effective Time and a payment date on or prior to the date of issuance of such ADSs and (y) at the appropriate payment date, the dividends or other distributions payable with respect to such ADSs that have a record date after the Effective Time and a payment date after the date of issuance of such ADSs.

(e) No Further Transfers. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time.

(f) Fractional Shares.

(i) No certificates, receipts or scrip representing fractional ADSs shall be issued upon the surrender of Company Certificates or transfer of Book Entry Shares, and such fractional ADS interests will not entitle their owners to vote, to receive dividends or other distributions or to any other rights of a shareholder of Parent. Each holder of Company Certificates or Book Entry Shares who would otherwise have been entitled to receive a fraction of an ADS under this Article II (after taking into account all Company Certificates delivered by such holder) shall receive from the Exchange Agent, in accordance with the provisions of this Article II, a cash payment in United States dollars in lieu of such fractional share interest either (A) representing that holder’s proportionate interest in the net proceeds from the sale by the Exchange Agent in one or more transactions of the aggregate of the fractional ADSs which would otherwise have been issued under this Article II (the “Excess ADSs”) or (B) in accordance with Section 2.3(f)(ii). The sale of the Excess ADSs shall be (A) executed on The NASDAQ Stock Market and (B) made at such times, in such manner and on such terms as the Exchange Agent shall determine in its reasonable discretion. Until the net proceeds of such sale or sales have been distributed to the holders of Company Certificates in accordance with this Section 2.3, the Exchange Agent shall hold the net proceeds in trust (the “Exchange Trust”) for those holders. All commissions, fees, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent, incurred in connection with the sale of the Excess ADSs shall be paid by Parent and the Surviving Corporation. As soon as practicable after the determination of the amount of cash to be paid to holders of Company Certificates and Book Entry Shares in lieu of fractional ADSs, the Exchange Agent shall make that amount available to those holders, without interest. The Exchange Agent shall determine the portion of the net proceeds to which each holder of Company Certificates or Book Entry Shares shall be entitled by multiplying the aggregate amount of the net proceeds by a fraction of which (1) the numerator is the amount of the fractional share interest to which such holder of Company Certificates or Book Entry Shares is entitled (after taking into account all Company Certificates delivered by such holder) and (2) the denominator is the aggregate amount of fractional share interests to which all holders of Company Certificates and Book Entry Shares are entitled.

(ii) Notwithstanding the provisions of Section 2.3(f)(i), Parent may elect, at its option exercised prior to the Effective Time, to pay to the Exchange Agent an amount in cash in United States dollars, to be deposited on the first Business Day following the Effective Time, sufficient for the Exchange Agent to pay each holder of Company Certificates or Book Entry Shares an amount in cash equal to the product obtained by multiplying (A) the fraction of an ADS to which such holder would otherwise have been entitled by (B) the closing price for an ADS on The NASDAQ Stock Market on the first Business Day immediately following the Effective Time. In such event, all references in this Agreement to the net proceeds from the sale of the Excess ADSs and similar references shall be deemed to refer to the payments calculated in the manner set forth in this Section 2.3(f)(ii).

(g) Required Withholding. Parent, the Company, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from any payments or consideration made pursuant to this Agreement such amounts or such number of ADSs as they may be required to deduct and withhold from such payment or consideration under any applicable Tax Laws, including the ITO; provided, however, that if Parent, the Exchange Agent or the Surviving Corporation are provided at least three (3) Business Days prior to any payment payable pursuant to this Agreement with what Parent, the Exchange Agent or the Surviving Corporation determines in their reasonable discretion to be a valid approval or ruling issued by the ITA (including the Tax Rulings) regarding the deduction or withholding of tax (including the reduction of tax to be withheld, an exemption from withholding or any other instructions regarding the payment of withholding) (the “Israeli Tax Certificate”) from any consideration payable to such payee hereunder, then the withholding (if any) of any amounts under the ITO, from the consideration payable to such payee hereunder, and the payment of the consideration or any portion thereof, shall be made only in accordance with the provisions of such Israeli Tax Certificate. If Parent, the Company, the Surviving Corporation or the Exchange Agent, as the case may be, deducts or withholds any such amounts, such amounts shall be treated for all purposes as having been paid to the Person in respect of whom Parent, the Company, the Surviving Corporation or the Exchange Agent, as the case may be, made such deduction and withholding.

(h) Termination of Exchange Fund and Exchange Trust. Any portion of the Exchange Fund or the Exchange Trust that remains unclaimed by the holders of Company Certificates one year after the Effective Time shall be delivered by the Exchange Agent to Parent upon demand. Any holder of Company Certificates who has not complied with this Article II shall look thereafter only to Parent for payment of the Merger Consideration.

(i) No Liability. None of Parent, the Surviving Corporation or the Exchange Agent shall be liable to any holder of Company Certificates for any Merger Consideration properly delivered to a public official under any applicable abandoned property, escheat or similar Laws.

(j) Lost, Stolen or Destroyed Certificates. If any Company Certificate is lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Certificate to be lost, stolen or destroyed, the Exchange Agent shall issue the Merger Consideration in exchange for such lost, stolen or destroyed Company Certificate.

Section 2.4 Treatment of Stock Options, RSUs and ESPP.

(a) As of the Effective Time, each option to acquire shares of Company Common Stock outstanding immediately prior to the Effective Time (“Company Stock Options”) and issued under any “Company Option Plans” (as defined below), shall be assumed and converted (as converted, a “Converted Stock Option”), by virtue of the Merger and without any action on the part of the holder of that Company Stock Option, into an option exercisable for that number of ADSs equal to the product of (i) the aggregate number of shares of Company Common Stock for which such Company Stock Option was exercisable multiplied by (ii) the Exchange Ratio, rounded down to the nearest whole share. The exercise price per share of such Converted Stock Option shall be equal to (x) the per share exercise price of such Company Stock Option immediately prior to the Effective Time divided by (y) the Exchange Ratio, rounded up to the nearest cent.

(b) As of the conversion pursuant to Section 2.4(a), each Converted Stock Option shall have, and be subject to, the same terms and conditions set forth in the applicable Company Option Plan and the option agreement pursuant to which the corresponding Company Stock Option was granted, as in effect immediately prior to the Effective Time, except as otherwise provided herein or in the applicable Company Stock Option Plan and the option agreement pursuant to which the corresponding Company Stock Option was granted.

(c) To the extent that any Company Stock Option constituted an “incentive stock option” (within the meaning of Section 422 of the Code) immediately prior to the Effective Time, such Company Stock Option shall continue to qualify as an “incentive stock option” to the maximum extent permitted by Section 422 of the Code.

(d) Parent shall convert Company Stock Options into Converted Stock Options in such a manner as to ensure that the Converted Stock Options are not subject to Section 409A of the Code as a result of such assumption and conversion.

(e) As of the Effective Time, each restricted stock unit with respect to shares of Company Common Stock granted under a Company Option Plan that is outstanding immediately prior to the Effective Time (each, a “Company RSU”) shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into a restricted stock unit, on the same terms and conditions (including applicable vesting requirements and deferral provisions) as applied to each such Company RSU immediately prior to the Effective Time, with respect to the number of ADSs that is equal to the number of shares of Company Common Stock subject to the Company RSU immediately prior to the Effective Time multiplied by the Exchange Ratio (rounded to the nearest whole share) (a “Converted Parent RSU”). As of the Effective Time, each Converted Parent RSU shall have, and be subject to, the same terms and conditions set forth in the applicable Company Option Plan and the Company RSU agreement pursuant to which the corresponding Company RSU was granted, as in effect immediately prior to the Effective Time, except as otherwise provided herein or in the applicable Company Option Plan and the Company RSU agreement pursuant to which the corresponding Company RSU was granted.

(f) Parent will (i) reserve for issuance the number of ADSs and underlying Parent Ordinary Shares that will become subject to the Converted Stock Options and Converted Parent RSUs referred to in this Section 2.4 and (ii) issue or cause to be issued the appropriate number of ADSs and underlying Parent Ordinary Shares, upon the exercise of the Converted Stock Options and Converted Parent RSUs. As soon as practicable after the Effective Time, Parent will prepare and file with the SEC a registration statement on Form S-8 (or other appropriate form) registering a number of Converted Parent RSUs and underlying Parent Ordinary Shares necessary to fulfill Parent’s obligations under this Section 2.4. Such registration statement will be kept effective (and the current status of the prospectus required thereby will be maintained) for at least as long as Converted Stock Options and Converted Parent RSUs remain outstanding.

(g) Prior to the Effective Time, the Company and Parent shall cooperate in taking all actions that are necessary to cause the Company Stock Options and Company RSUs to be assumed and converted as provided in this Section 2.4. As soon as practicable after the Effective Time, Parent will deliver to the holders of the Converted Stock Options and Converted Parent RSUs appropriate notices setting forth the effect of the Merger on such holders’ rights pursuant to the Company Stock Plans and the agreements evidencing the grants of such Company Stock Options and that such Company Stock Options and Company RSUs will continue in effect as the Converted Stock Options and Converted Parent RSUs on the same terms and conditions (subject to the adjustment required by this Section 2.4 after giving effect to the Merger).

(h) Each outstanding right to purchase shares of Company Common Stock under any outstanding offering period as of the date of this Agreement under the 1995 Employee Stock Purchase Plan (the “ESPP”) shall terminate not later than the day immediately prior to the day on which occurs the Effective Time, provided that the Company may permit each participant in the ESPP to purchase from the Company as many whole shares of Company Common Stock as the balance of the participant’s account will allow, at the applicable price determined under the terms of the ESPP for each such outstanding offering period, using such date as the final purchase date for such offering period, and any amounts remaining in any participant’s account after any such purchase will be refunded to the participant.

Section 2.5 No Appraisal Rights. No appraisal rights will be available to the stockholders of the Company in connection with the Merger.

Each of Parent and the Company shall use commercially reasonable efforts to (i) notify the other party, counsel to Parent and counsel to the Company if Parent or the Company (as applicable) becomes aware of any facts that would make any of the representations set forth in its letter untrue at the Effective Time or at the time of the filing of the Form F-4 Registration Statement and (ii) promptly provide to the other party, counsel to Parent, and counsel to the Company a revised form of letter that reflects such updated facts.

(e) The parties hereto acknowledge that (i) the agreements contained in this Section 7.5 are an integral part of the transactions contemplated by this Agreement and (ii) without these agreements, the parties would not have entered into this Agreement. Accordingly, if either party fails promptly to pay any amount payable by it pursuant to this Section 7.5, and, in order to obtain such payment, the other party commences a suit which results in a judgment against the non-paying party for the payment set forth in this Section 7.5, the non-paying party shall pay to the other party its costs and expenses (including attorneys’ fees, charges and disbursements) in connection with such suit, together with interest on the amount due from each date for payment until the date of such payment at the prime rate of Citibank N.A. in effect on the date such payment was required to be made plus 2 percent.

(f) The parties to this Agreement intend, and shall use all reasonable endeavors to secure, that any amounts payable pursuant to Section 7.5(c) and Section 7.5(d) are not treated for VAT purposes as consideration for a taxable supply. In circumstances where a payment falls to be made in accordance with Section 7.5(c) or Section 7.5(d), if and to the extent that any relevant Tax authority determines that the amount which would otherwise be payable pursuant to Section 7.5(c) or Section 7.5(d) but for the adjustment required pursuant to this section 7.5(f) (each, a “Termination Fee”) is consideration for a taxable supply, that the party paying the Termination Fee (or the representative member of a VAT Group of which that party is a member) is liable to account to a Tax authority for VAT in respect of such supply and all or any part of such VAT is Irrecoverable VAT, then:

(i) the amount payable by such party pursuant to Section 7.5(c) or Section 7.5(d) shall be reduced so that the amount payable, together with any Irrecoverable VAT arising in respect of the supply for which the payment is consideration, is equal to the Termination Fee; and

(ii) to the extent that such party has already paid an amount in respect of the Termination Fee which exceeds the amount described in Section 7.5(f)(i) above, the other party shall repay to such party such amount as will ensure that the aggregate amount paid by such party pursuant to Section 7.5(c) or Section 7.5(d), together with the Irrecoverable VAT mentioned in Section 7.5(f)(i) above and less the repayment mentioned in this Section 7.5(f)(ii), is equal to the Termination Fee.

Section 7.6 Amendment. This Agreement may be amended by the parties to this Agreement at any time prior to the Effective Time, so long as (a) no amendment that requires stockholder or shareholder approval under applicable Laws shall be made without such required approval and (b) such amendment has been duly approved by the board of directors of each of Parent, Merger Sub and the Company. This Agreement may not be amended except by an instrument in writing signed by each of the parties to this Agreement.

Section 7.7 Extension; Waiver. At any time prior to the Effective Time, Parent and Merger Sub, on the one hand, and the Company, on the other hand, may (a) extend the time for the performance of any of the obligations of the other party, (b) waive any inaccuracies in the representations and warranties of the other party contained in this Agreement or in any document delivered under this Agreement or, (c) subject to applicable Laws, waive compliance with any of the covenants or conditions contained in this Agreement. Any agreement on the part of a party to any extension or waiver shall be valid only if set forth in an instrument in writing signed by such party. The failure or delay of any party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.
