For the avoidance of all doubts, it is hereby cleared that any Option granted to the Employee under this Agreement, shall be in addition to any other options that may have been granted to the Employee prior to this Agreement.

The Option is granted pursuant to Section 102, through a trustee and in accordance with the capital gains route.

Without derogating from any other provisions of the Plan and this Agreement, including with respect to the assignment, sale or other transfer of the Option or the Shares, (i) the Option and the Shares may not be sold until the end of the Restricted Period, unless otherwise allowed or determined by the Israeli tax authorities; and (ii) all Additional Rights, if any, will be subject to the same tax route applicable to the Option and/or the Shares.

The term of the Option shall be 10 years from the date hereof or such shorter period as is prescribed in Section 3.3 below or pursuant to the Plan.

3.2. The following are the dates as of which the Option may be exercised (each an “Exercise Date”) by the Trustee pursuant to the Employee’s instructions and the number of Shares which may be purchased thereunder on each such Exercise Date:

5. Employee Representations, Warranties and Covenants

Without derogating in any manner from the provisions of the Plan or this Agreement, the Employee hereby represents, warrants, agrees and undertakes as follows:

5.1. The shares to be acquired upon exercise of the Option shall be purchased for the Employee’s own account for investment purposes only and not with a view for resale, distribution or transfer, and all the rights pertaining to the Shares, by law or equity, shall be purchased and possessed by the Employee (through the Trustee) for the Employee exclusively. The Company may require, as a condition to the exercise of the Option, that the Employee reconfirm, represent and agree that the Shares being acquired upon exercise are being acquired for the Employee’s own account for investment purposes only and not with a view for resale or distribution and that the Employee make such other representations as the Company deems necessary, advisable or appropriate.

5.2. That he or she acknowledges that the Company’s shares are not publicly traded and understands that the Company bears no responsibility and has made no commitment to register its shares, or the Options or Shares allotted to the Employee (through the Trustee), for trading or to offer its shares to the public in any manner.

5.3. The Employee acknowledges and agrees that no income or gain which the Employee may be credited with or which purports to be credited to the Employee as a result of the grant of the Option, the exercise thereof, the issue of the Shares, the transfer into the Employee’s name thereof or the sale thereof, if any, shall in any manner be taken into account in the calculation of the basis for the Employee’s entitlements from the Company or any Related Company or in the calculation of any social welfare right or other rights or benefits arising out of the employee/employer relationship, including without limitation, social security, health tax, manager’s insurance, educational fund, pension funds, severance pay, holiday pay, etc.

In the event that the Company and/or any Related Company shall be required, pursuant to any law, to take into account for purposes of calculating any such benefits, any of the aforesaid elements of income or gain actually or theoretically credited to the Employee, the Employee shall promptly indemnify the Company and/or any Related Company against any expense caused to it in this regard, and any such amount shall be deemed a debt of the Employee to the Company and/or any Related Company, which may be deducted or set off from any amounts payable to the Employee.

5.4. The Employee acknowledges that nothing in this Agreement and/or in the Plan shall be interpreted as a commitment and/or an agreement by the Company and/or any Related Company to employ the Employee, whether for a certain period or otherwise, and that nothing in this Agreement and/or the Plan or any option granted pursuant hereto or thereto shall be interpreted as conferring upon the Employee any right to continue in the employment of the Company or any Related Company or as obliging the Company or any Related Company to employ the Employee or as restricting the rights of the Company and/or any Related Company to terminate the Employee’s employment, at any time, at its sole discretion and in accordance with law. The Employee shall have no claim whatsoever against the Company and/or any Related Company as a result of the termination of his or her employment, even if such termination causes the Option or any other options, in whole or in part, to expire and/or prevents him or her from exercising the Option in whole or in part and/or from receiving or retaining the Shares pursuant hereto or to any other agreement between him or her and the Company, or results in any loss due to any imposition, or earlier than anticipated imposition, of tax or other liability pursuant to applicable law.

5.5. The Employee acknowledges that the grant of the Option and the issue of the Shares, the execution of this Agreement and the Employee’s participation in the Plan shall have tax consequences to the Employee, and that the Company is not able to ensure or represent to the Employee the nature and extent of such tax consequences.

The Company may require as a condition to the exercise of the Option that the Employee pay or otherwise make arrangements to the Company’s and Trustee’s satisfaction, for the payment of the tax and other obligatory payments applicable to him or her (including all sums payable arising out of or in connection with the Company’s obligation to deduct tax and other obligatory payments at source) pursuant to applicable law and the provisions of the Plan.

The Employee acknowledges and agrees, that pursuant to the Plan, the Employee shall be liable to pay all taxes, of every nature, including duties, fines and any other payment which may be imposed by the tax authorities, whether in Israel or abroad, and all expenses arising out of the Plan, including every obligatory payment of whatever source (including, but not limited to, social security, health tax, etc. as may be applicable) in respect of the Option, the Shares (including, without limitation, upon the grant of the Option, the exercise of the Option, the issuance of the Shares, the sale of the Shares or the registration of the Shares in the Employee’s name) or dividends or any other benefit in respect thereof, and/or all other charges which may accrue to the Employee, the Company, any Related Company and/or the Trustee in connection with the Plan, the Option and/or the Shares, or any act or omission by the Employee or the Company in connection therewith, or pursuant to any determination by the applicable tax or other authorities, including, without limitation, any such payments required to be made by the Company as the result of any sale by the Employee of any of the Shares prior to the end of the Restricted Period, and whether or not the provisions of the Income Tax Ordinance or Section 102 apply. Furthermore, the Employee acknowledges that the Employee shall not have, and the Employee hereby waives, any complaint and/or cause of action the same has or shall have in the future against the Trustee and/or against the Company and/or against any Related Company in any way connected to any taxation resulting from the grant of the Option, the exercise thereof, the issuance of the Shares, the transfer of Shares into the Employee’s name, the sale of Shares by the Employee and/or by the Trustee and/or any other matter which is in any manner whatsoever connected to the Option, the Shares and/or the participation of the Employee in the Plan.

The Employee further acknowledges and agrees that, without derogating from the Employee’s obligation to pay all taxes payable with respect to the Option and the Shares, the Company and/or any Related Company and/or the Trustee shall at their absolute sole discretion be entitled (and/or obliged pursuant to applicable law), to deduct at source from all the payments due to the Employee, including dividends, consideration for the sale of shares or from any other source, any tax or obligatory payments due to the tax or other authorities in respect of the Option or the Shares pursuant to any law.

Without derogating from the above, the Company (including any Related Company) and/or the Trustee shall have the right to require that the Employee provide guarantees or other security to the Company’s satisfaction to guarantee the payment of any taxes or other obligatory payments which may be payable as a result of or in connection with the grant of the Option, the exercise thereof, the issuance, sale or transfer of any of the Shares and/or the registration thereof in the Employee’s name (including any sums payable arising out of or in connection with the Company’s obligations to deduct tax and other obligatory payments at source).

5.6. The Employee acknowledges that he or she is aware of, and clearly understands: (a) the rights and limitations attached to the Shares as set forth in the Company’s Articles of Association, the Plan and this Agreement; (b) the limitations on transferability thereof set forth in the Articles of Association, the Plan and this Agreement; (c) that the Company’s Articles of Association may be amended from time to time as permitted by law; and (d) that the provisions of the Articles of Association of the Company which shall apply to the Shares shall be the provisions which shall be in effect from time to time; and that, as a result, inter alia, of these limitations, it may be difficult or impossible for the Employee to realize his investment and/or to sell or otherwise transfer the Shares.

5.7. In the event that the Company’s Articles of Association, now or at any time hereafter, provide for a right of first refusal to purchase shares of the Company which are offered for sale by other shareholders of the Company and/or a pre-emptive right to purchase shares which are being allotted or shall in the future be allotted by the Company, the Employee hereby waives such rights. For the purpose of the approval of any transfer or the execution of any issue as aforesaid, this Agreement shall constitute an authorization, for the benefit of the Company and the Company’s shareholders, to the Trustee, until the consummation of the IPO, to sign any confirmation or waiver in the name of the Employee and on his or her behalf. The Employee shall not sell, and shall not instruct the Trustee to sell, the Shares or any part thereof to any third party, unless such third party signs a waiver and a power of attorney as aforesaid and the Proxy and Power of Attorney.

6

5.10.

For as long as any shares are held by the Trustee or registered in his name or for as long as the certificates representing any shares are held by the Trustee, the Trustee alone shall be entitled to receive every notice to which a shareholder is entitled or to demand any information, and any financial and/or other report to which a shareholder is entitled from the Company, and he alone or whomever he shall designate pursuant to the Proxy and Power of Attorney shall have the right to exercise every other right of the shareholders vis-à-vis the Company including the right to participate in and vote at all shareholders’ meetings. The Employee shall not be entitled to exercise any of these rights as shareholder nor make any demand or request of the Trustee and/or of the Attorney in this regard. Without derogating from the generality of the above, the Employee shall not have nor exercise any voting rights with respect to the Shares until they are transferred and registered in his name in the Company’s register of members pursuant to the Plan.

5.11.

That until the consummation of the IPO, the Employee shall provide any certificate, declaration or other document and shall perform any act which the Company or the Trustee shall consider to be necessary or desirable whether pursuant to any law, whether local or foreign, or otherwise, including any undertaking on the part of the Employee not to sell the Shares during any period which shall be required by an underwriter or investment bank or advisor of the Company for the purpose of any share issue, whether private or public (including lock-up and/or market stand-off arrangements and undertakings), and including any certificate or agreement which the Company shall require, if any, from the Employee as a member of a class of shareholders, or any certificate, declaration or other document the obtaining of which shall be deemed by the Board or the Trustee to be appropriate or necessary for the purpose of raising capital for the Company, of merging the Company with or into another company (whether the Company is the surviving entity or not), or of reorganization of the Company, including, in the event of a consolidation or merger of the Company or any sale, lease, exchange or other transfer of all or substantially all of the assets or shares of the Company, for the sale or exchange, as the case may be, of any shares or rights to purchase shares the Employee (or the Trustee on his or her behalf) may have purchased or been granted hereunder all as shall be deemed necessary or desirable by the Board or the Trustee.

As long as the Shares and/or the Option are registered in the Trustee’s name, the same shall be authorized to sign the Employee’s name and on his/her behalf on any of the aforesaid documentation. In the event that the Option or any or all of the Shares have been transferred into the name of the Employee, and he/she has refused to confirm any document required by the Company as aforesaid by placing his/her signature thereon, the Trustee shall be entitled, at the request of the Company, to sign any document in the name of the Employee and on his/her behalf

In order to guarantee, and without derogating from, the aforesaid, and because the rights of the Company and the other shareholders are dependent thereon, the Employee shall, upon signing this Agreement and as a condition to the grant of any options hereunder, execute the Proxy and Power of Attorney irrevocably empowering the Trustee and/or the Attorney, until consummation of the IPO, inter alia, to sign any document and take any action in his or her name as aforesaid and the Employee shall have no complaint or claim against the Trustee and/or the Attorney in respect of any such signature or action or in respect of any determination of the Trustee pursuant to the Plan or hereto.
