From time to time the Board may increase the size of the Committee and appoint additional members, remove members (with or without cause) and appoint new members in substitution therefor, fill vacancies, however caused, and remove all members of the Committee and thereafter directly administer the Plan, to the extent permitted by the applicable laws and regulations. 4.2 Powers of the Committee Subject to the provisions of the Plan and the authorization given by the Board, the Committee shall have the authority, in its discretion: (a) to determine the Fair Market Value of the Shares, in accordance with the definition of Fair Market Value as stated in Section 2 of the Plan; (b) to select the Employees to whom Options shall be granted hereunder; (c) to determine whether and how many Options shall be granted hereunder; (d) to approve instruments or documents to be used under the Plan, including the Option Agreement; (e) to determine the terms and conditions, subject to the terms of the Plan, of any Option granted hereunder (including, but not limited to, the share price and any restriction or limitation, vesting schedules or other restrictions regarding any Option and/or the Shares relating thereto), provided that the term of the Option (i.e. the period the Option remains exercisable) shall not exceed the maximum period of time permitted under the applicable laws; (f) to determine whether and under what circumstances an Option may be exercised and Shares may be transferred in compliance with the laws of the Republic of Singapore; (g) to interpret and administer the Plan and any instrument or document relating to the Plan; and (h) to make any other determination and take any other action that the Committee deems necessary or desirable for the administration of the Plan. All decisions, determinations and interpretations of the Committee shall be final and binding on all persons, including the Company, the Company's Subsidiaries, any Optionee and any other holder or beneficiary of an Option or the Employee. 4.3 The Committee may delegate to one or more managerial officers of the Company or its Subsidiaries or to a committee composed of such managerial officers the authority to administer the Plan with respect to employees other than managerial officers pursuant to the authorization given by the Committee. 4.4 Each Option granted under the Plan shall be evidenced by an Option Agreement specifying the terms and conditions of the Option and any rules applicable thereto. 5. Eligibility 5.1 Options may be granted to the Employees of the Employer as determined by the Committee, pursuant to the Option Agreement executed by the Optionee and the Company. The Committee shall have sole and complete authority to determine the Employees to whom Options shall be granted, the number of Shares to be covered by each Option and the conditions and limitations applicable to the exercise of the Option. 5.2 No Employee or other persons shall have any claim to be granted any Option, and the Employee's exercise of any Option is subject to the restrictions imposed by the Committee as it may deem advisable under the Plan, local laws and regulations, the requirements of the stock exchange on which the stocks of the Company are listed and other applicable rules, laws and regulations. There is no obligation for the Company to treat all the Employees, holders or beneficiaries of Options under the same terms and conditions. 5.3 The eligibility for Options awarded under the Plan are conditioned upon an Employee's Continuous Status as an Employee and the Options granted under the Plan are subject to Section 10 of this Plan. However, nothing contained in the Plan or the Option Agreement nor any Option granted hereunder shall confer upon any Optionee the right to continuation of employment or consulting relationship with the Employer or interfere in any way with the Employee's right or the Employer's right to terminate his employment or consulting relationship at any time, with or without cause. 6. Term of Plan The Plan shall become effective upon the adoption by the Shareholders of the Company in General Meeting. It shall continue in effect until the date on which all shares available for issue under the Plan have been issued as fully-vested shares, or the termination of all outstanding options in connection with a merger under Section 9.3, or terminated under Section 11 of the Plan, or the elapsing of ten years from the effective date, whichever is earlier. 7. Option Exercise Price and Consideration 7.1 The per Share exercise price shall be no less than the par value of a Share. 7.2 The payment of the consideration for the Shares to be issued upon exercise of an Option shall be determined by the Committee and, subject to the discretion of the Committee, may consist entirely of (1) cash, (2) check, (3) any combination of the foregoing methods of payment, or (4) such other considerations and methods of payment for the transfer of Shares to the extent permitted under applicable laws and regulations or the rules or regulations of the stock exchange on which the Shares of the Company are listed. 7.3 All taxes (including income tax) arising from the exercise of any Option by an Optionee under the Plan shall be borne by the Optionee. The Optionee shall be required to pay to the Company or its Subsidiaries the amount of any applicable withholding taxes arising out of an Option, including but not limited to the exercise of Options or transfer of shares, under the Plan, if applicable; otherwise, the Company or its Subsidiaries shall have the right and is hereby authorized to withhold from any compensation, amount or value owing to the Optionee the amount or value equal to the amount of tax due and to take such other actions as may be necessary in the opinion of the Company to satisfy all obligations for the payment of such taxes, if required by applicable law. 8. Exercise 8.1 An Option shall be exercised in accordance with the terms and conditions listed in the Option Agreement or otherwise directed by the Committee in writing. An Option may not be exercised for a fraction of a share. An Option shall be deemed to be exercised upon the Company's receipt of a written notice of such exercise made in accordance with the terms of the Option Agreement under which the Option is granted and the full payment for the Shares to be issued. Full payment may, as authorized by the Committee, consist of any consideration and method of payment allowable under Section 7.2 of the Plan. The Optionee, holder or the beneficiary of the option are not entitled to exercise the right to vote or receive dividends or any other rights as a shareholder with respect to the Shares subject to the Option notwithstanding the exercise of the Option until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the share certificates evidencing such Shares. The Company shall issue (or cause to be issued) such share certificates promptly upon exercise of the Option. Notwithstanding any provision contained herein, the Committee and the Company shall not under any circumstances be held liable for any cost, losses, expenses and damages arising in any event, including but not limited to the Company's delay in issuing the Shares. The Optionee is not entitled to any adjustment for dividends or other rights of which the Record Date is prior to the date the share certificate is issued, unless otherwise provided in the Plan. For the purpose of this sub-Section, the term "Record Date" refers to the date fixed by the Company for the purposes of determining entitlements to dividends or other distributions to or rights of shareholders. 8.2 Conditions Upon Transfer of Shares Shares shall not be issued pursuant to the exercise of any Option unless the exercise of such Option and the delivery of such Shares shall comply with all relevant provisions of applicable laws and regulations, the requirements of the stock exchange on which the shares of the Company are listed and shall be further subject to the approval of counsel for the Company with respect to such compliance. Each Option shall be exercisable at such times and subject to such terms and conditions as the Committee may, in its sole discretion, specify in the applicable Option Agreement or other written instruments in relation to the Plan. The Committee may impose such conditions to the exercise of Options, including, without limitation, any relating to the application of the local laws and regulations, the requirements of the stock exchange on which the shares of the Company are listed or other applicable laws or regulations, as it deems necessary or advisable. The inability of the Company to obtain authority from any regulatory body and/or self-regulatory organization having jurisdiction over the Company or its Subsidiaries, which authority is deemed by the Company's counsel to be necessary to the lawful sale of any shares hereunder, shall relieve the Company of any liability in respect of the failure to issue such Shares. 9. Adjustment 9.1 In order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available to the Employees under the Plan, and subject to any required action by the shareholders and the Board of the Company and the terms and conditions of the Plan, the Committee shall adjust the number of Shares subject to outstanding Options or Options to be granted and the grant or exercise price of any Option for any increase or decrease in the number of issued shares resulting from a scrip dividend, combination or reclassification of the Shares, reorganization, merger, consolidation, split-up, spin-off, combination, exchange of Shares or other securities of the Company or other similar events. 9.2 Upon any adjustment required to be made pursuant to Section 9.1, the Company shall notify the Optionee in writing and deliver to him a statement setting forth the exercise or grant price thereafter in effect and the class and/or number of Shares thereafter to be issued on the exercise of the Option. Any adjustment shall take effect upon such written notification being given. 9.3 In the event of the proposed dissolution or liquidation of the Company, the Board shall notify the Optionee at least 10 days prior to such proposed action. Options not exercised shall terminate immediately prior to the consummation of such proposed action. In the event of a merger of the Company with or into another corporation, the Option shall be assumed or an equivalent option shall be substituted by such successor corporation. In the event that such successor corporation does not agree to assume the Option or the substitute of an equivalent option, the Optionees shall be entitled to exercise all the Options that are exercisable on the date of the proposed merger during a reasonable period of time as determined by the Committee. The Committee shall notify the Optionees in writing of the fact that the Option shall be fully exercisable during a given period of time, and the Options will terminate upon expiration of such period. 10. If the Optionee's employment with the Employer is terminated for any reason howsoever arising, the rights (if any) of the Optionee or his successor (as in the case of the Optionee's death) to exercise any Option and if so, the terms on which such rights may be exercised, shall, unless otherwise specified in the Option Agreement, be determined at the sole discretion of the Committee. 11. Amendment and Termination. 11.1 The Board may amend, alter, suspend, discontinue or terminate the Plan or any portion thereof at any time; provided that no such amendment, alteration, suspension, discontinuation or termination shall be made without shareholder's approval if such approval is necessary under applicable laws or regulations. Notwithstanding anything to the contrary herein, the Board may amend the Plan in such manner as necessary to make the Plan in conformity with local rules and regulations in any jurisdiction. 11.2 The Committee may waive or amend any terms of, or alter, suspend, discontinue, cancel or terminate any Option granted hereunder, prospectively or retroactively, provided that the Optionee being adversely affected by such change consents in writing to such change of the Options. 12. The Option may not be sold, pledged, assigned, disposed, transferred, or encumbered of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. 13. The Company shall provide to each Optionee, during the period for which such Optionee has one or more Options outstanding, copies of all annual reports and other information which are provided to all shareholders of the Company. 14. Nothing contained in the Plan shall prevent the Company or its Subsidiaries from adopting or continuing in effect other compensation arrangements which may or may not provide for the grant of options of shares. 15. The grant of an Option or any thing contained in the Plan or the Option Agreement shall not be construed as conferring upon the Optionees any right with respect to continuation of employment by the Company, nor shall it interfere in any way with the Employer's right to terminate the employment at any time, with or without cause. The terms of employment of an Employee shall not be affected by the execution of the Plan. The Options granted under the Plan shall not form a part of the terms of employment of an Employee or entitle him to take into account the Options granted under the Plan in calculating any compensation or damages on the termination of his employment for any reason. 16. The validity, interpretation and application of the Plan shall be governed by the laws of the Republic of Singapore. 17. Any provision of this Plan or the Option Agreement which is invalid or unenforceable in whole or in part or shall cause the disqualification of the Company from the application of any laws, regulations, rules or requirements of which the qualification is deemed necessary by the Board, shall be construed in a way that will satisfy the requirements under such laws, regulations and requirements. If it cannot be so construed, such provision shall be severable in whole or part from the Plan or the Option Agreement, so that such invalidity, unenforceability or disqualification shall not affect any other provision hereof. 18. The Plan or the Option Agreement shall not be construed as creating a trust or separate fund of any kind or a fiduciary relationship between the Company or its Subsidiaries and an Optionee or any other person. The right of any person to receive payments from the Company under the Plan or the Agreement shall be no greater than the right of any unsecured general creditor of the Company.

The inability of the Company to obtain authority from any regulatory body and/or self-regulatory organization having jurisdiction over the Company, which authority is deemed by the Company's counsel to be necessary to the lawful issuance of any shares hereunder, shall relieve the company of any liability in respect of the failure to sell such Shares. 5.2 This Option may not be exercised for a fraction of a share. 5.3 Once vested, this Option may be exercised up to the expiration date of the term of this Option as set forth in Annex A. 5.4 As a condition to the exercise of this Option, the Company may require the Optionee to make any representation and warranty to the Company as may be required by any applicable laws and regulations. 6.

Other Laws. 10.1 The Committee may refuse to issue any Shares, if, acting in its sole discretion, it determines that the issuance or transfer of such Shares might violate any applicable law or regulation or entitle the Company to recover under Section 16(b) of the Exchange Act of the United States, and in such event any payment tendered to the Company by an Optionee, other holder or beneficiary in connection with the exercise of such Option shall be promptly refunded to the relevant Optionee, holder or beneficiary. Without limiting the generality of the foregoing, the Option granted hereunder shall be construed as an offer to acquire or to sell Shares of the Company, and no such offer shall be outstanding, unless and until the Committee in its sole discretion has determined that any such offer, if made, would be in compliance with all applicable requirements of the U.S. federal securities laws and any other laws to which such offer, if made, would be subject. 10.2 If at any time the Committee shall determine in its discretion that the Shares subject to the Option granted hereunder must be listed or qualified on any securities exchange or registered or qualified under any applicable law or that the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with the granting of the Option, or the delivery or purchase of Shares pursuant to the Option, such Option may not be exercised in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained. 11. No Rights to Continuation of Employment Nothing in this Agreement, nor in the Plan which is incorporated herein by reference, shall confer upon the Optionee any right with respect to continuation of employment by the Company or the Subsidiary, nor shall it interfere in any way with the right of the Company or the Subsidiary to terminate his employment at any time, with or without cause. 12.
