Unless otherwise provided by the Board, if there is no closing sales price (or closing bid if no sales were reported) for the Common Stock on the date in question, then the Fair 4.

If any Option shall for any reason expire or otherwise terminate, in whole or in part, without having been exercised in full, the shares of Common Stock not acquired under such Option shall revert to and again become available for issuance under the Plan. If any shares subject to an Option are not delivered to an Optionholder because such shares are withheld for the payment of taxes or the Option is exercised through a reduction of shares subject to the Option (i.e., "net exercised"), the number of shares that are not delivered to the Optionholder as a result thereof shall remain available for issuance under the Plan. If the exercise price of an Option is satisfied by tendering shares of Common Stock held by the Optionholder (either by actual delivery or attestation), then the number of shares so tendered shall remain available for issuance under the Plan. (c) SOURCE OF SHARES. The shares of Common Stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. 5. ELIGIBILITY. The Options, as set forth in Section 6, automatically shall be granted under the Plan to all Non-Employee Directors who meet the criteria specified in Section 6. 6. NON-DISCRETIONARY GRANTS. (a) INITIAL GRANTS. Without any further action of the Board, each person who after the IPO Date is elected or appointed for the first time to be a Non-Employee Director automatically shall, upon the date of his or her initial election or appointment to be a Non-Employee Director, be granted an Initial Grant to purchase twelve thousand five hundred (12,500) shares of Common Stock on the terms and conditions set forth herein. (b) ANNUAL GRANTS. Without any further action of the Board, on the date of each Annual Meeting, commencing with the Annual Meeting in 2007, each person who is then a Non- 7. Employee Director automatically shall be granted an Annual Grant to purchase five thousand (5,000) shares of Common Stock on the terms and conditions set forth herein; provided, however, that if a person who is first elected as a Non-Employee Director after the IPO Date has not been serving as a Non-Employee Director for the entire period since the preceding Annual Meeting, then the number of shares subject to such Annual Grant shall be reduced pro rata for each full quarter prior to the date of grant during such period for which such person did not serve as a Non- Employee Director. 7. OPTION PROVISIONS. Each Option shall be in such form and shall contain such terms and conditions as required by the Plan. Each Option shall contain such additional terms and conditions, not inconsistent with the Plan, as the Board shall deem appropriate. Each Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions: (a) TERM. No Option shall be exercisable after the expiration of ten (10) years from the date on which it was granted. (b) EXERCISE PRICE. The exercise price of each Option shall be one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. (c) CONSIDERATION. The purchase price of Common Stock acquired pursuant to an Option shall be paid, to the extent permitted by applicable law, either (i) in cash at the time the Option is exercised or (ii) at the discretion of the Board either at the time of the grant of the Option or subsequent thereto (1) by delivery to the Company of other Common Stock at the time the Option is exercised, (2) by a "net exercise" of the Option (as further described below), (3) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds or (4) in any other form of legal consideration that may be acceptable to the Board. Unless otherwise specifically provided in the Option, the purchase price of Common Stock acquired pursuant to an Option that is paid by delivery to the Company of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company that have been held for more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes). In the case of a "net exercise" of an Option, the Company will not require a payment of the exercise price of the Option from the Optionholder but will reduce the number of shares of Common Stock issued upon the exercise by the largest number of whole shares that has a Fair Market Value that does not exceed the aggregate exercise price. With respect to any remaining balance of the aggregate exercise price, the Company shall accept a cash payment from the Optionholder. Shares of Common Stock will no longer be outstanding under an Option (and will therefore not thereafter be exercisable) following the exercise of such Option to the extent of (i) shares used to pay the exercise price of an Option under a "net exercise", (ii) shares actually 8. delivered to the Optionholder as a result of such exercise and (iii) shares withheld for purposes of tax withholding. (d) TRANSFERABILITY. An Option is transferable by will or by the laws of descent and distribution. An Option also may be transferable upon written consent of the Company if, at the time of transfer, a Form S-8 registration statement under the Securities Act is available for the exercise of the Option and the subsequent resale of the underlying securities. In addition, an Optionholder may, by delivering written notice to the Company, in a form provided by or otherwise satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option. (e) VESTING. Options shall vest as follows: (i) Initial Grants: 1/36th of the shares of Common Stock subject to an Initial Grant shall vest monthly over three (3) years. (ii) Annual Grants: 1/12th of the shares of Common Stock subject to an Annual Grant shall vest monthly over one (1) year. (f) TERMINATION OF CONTINUOUS SERVICE. In the event that an Optionholder's Continuous Service terminates for any reason, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination of Continuous Service) but only within such period of time ending on the expiration of the term of the Option as set forth in the Option Agreement. If, after termination of Continuous Service, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. 8. SECURITIES LAW COMPLIANCE. The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Options and to issue and sell shares of Common Stock upon exercise of the Options; provided, however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Option or any Common Stock issued or issuable pursuant to any such Option. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Options unless and until such authority is obtained. 9. USE OF PROCEEDS FROM STOCK. Proceeds from the sale of Common Stock pursuant to Options shall constitute general funds of the Company. 10. MISCELLANEOUS. (a) ACCELERATION OF EXERCISABILITY AND VESTING. The Board shall have the power to accelerate the time at which an Option may first be exercised or the time during which an Option 9. or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in the Plan or the Option stating the time at which it may first be exercised or the time during which it will vest. (b) STOCKHOLDER RIGHTS. No Optionholder shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Option unless and until such Optionholder has satisfied all requirements for exercise of the Option pursuant to its terms. (c) NO SERVICE RIGHTS. Nothing in the Plan, any Option Agreement or other instrument executed thereunder or any Option granted pursuant thereto shall confer upon any Optionholder any right to continue to serve the Company as a Non-Employee Director or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant's agreement with the Company or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. (d) INVESTMENT ASSURANCES. The Company may require an Optionholder, as a condition of exercising or acquiring Common Stock under any Option, (i) to give written assurances satisfactory to the Company as to the Optionholder's knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Option; and (ii) to give written assurances satisfactory to the Company stating that the Optionholder is acquiring the Common Stock subject to the Option for the Optionholder's own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the shares of Common Stock upon the exercise or acquisition of Common Stock under the Option has been registered under a then currently effective registration statement under the Securities Act or (2) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. (e) WITHHOLDING OBLIGATIONS. To the extent provided by the terms of an Option Agreement, the Company may in its sole discretion, satisfy any federal, state or local tax withholding obligation relating to an Option by any of the following means (in addition to the Company's right to withhold from any compensation paid to the Optionholder by the Company) or by a combination of such means: (i) causing the Optionholder to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Optionholder in connection with the Option; or (iii) via such other method as may be set forth in the Option Agreement. 10. 11. ADJUSTMENTS UPON CHANGES IN COMMON STOCK. (a) CAPITALIZATION ADJUSTMENTS. If any change is made in, or other event occurs with respect to, the Common Stock subject to the Plan, or subject to any Option, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company (each a "CAPITALIZATION ADJUSTMENT")), the Plan will be appropriately adjusted in the class(es) and maximum number of securities subject both to the Plan pursuant to Section 4 and to the nondiscretionary Options specified in Section 6, and the outstanding Options will be appropriately adjusted in the class(es) and number of securities and price per share of Common Stock subject to such outstanding Options. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (Notwithstanding the foregoing, the conversion of any convertible securities of the Company shall not be treated as a transaction "without receipt of consideration" by the Company.) (b) DISSOLUTION OR LIQUIDATION. In the event of a dissolution or liquidation of the Company, then all outstanding Options shall terminate immediately prior to the completion of such dissolution or liquidation. (c) CORPORATE TRANSACTION. The following provisions shall apply to Options in the event of a Corporate Transaction unless otherwise provided in the instrument evidencing the Option or any other written agreement between the Company or any Affiliate and the holder of the Option or unless otherwise expressly provided by the Board at the time of grant of a Option. In the event of a Corporate Transaction, any surviving corporation or acquiring corporation may assume or continue any or all Options outstanding under the Plan or may substitute similar stock options for Options outstanding under the Plan (including options to acquire the same consideration paid to the stockholders of the Company, as the case may be, pursuant to the Corporate Transaction). In the event that any surviving corporation or acquiring corporation does not assume or continue all such outstanding Options or substitute similar stock options for all such outstanding Options, then with respect to Options that have been not assumed, continued or substituted and that are held by Optionholders whose Continuous Service has not terminated prior to the effective time of the Corporate Transaction, the vesting of such Options (and, if applicable, the time at which such Options may be exercised) shall (contingent upon the effectiveness of the Corporate Transaction) be accelerated in full to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five (5) days prior to the effective time of the Corporate Transaction), and such Options shall terminate on the effective time of the Corporate Transaction if not exercised (if applicable) at or prior to such effective time. With respect to any other Options outstanding under the Plan that have not been assumed, continued or substituted, the vesting of such Options (and, if applicable, the time at which such Options may be exercised) shall not be accelerated, unless otherwise provided in a written agreement between the Company or any Affiliate and the Optionholder, and such Options shall terminate if not exercised (if applicable) prior to the effective time of the Corporate Transaction. 11. (d) CHANGE IN CONTROL. An Option may be subject to additional acceleration of vesting and exercisability upon or after a Change in Control as may be provided in the Option Agreement for such Option or as may be provided in any other written agreement between the Company or any Affiliate and the Optionholder, but in the absence of such provision, no such acceleration shall occur. 12. AMENDMENT OF THE PLAN AND OPTIONS. (a) AMENDMENT OF PLAN. Subject to the limitations, if any, of applicable law, the Board, at any time and from time to time, may amend the Plan.

You may elect to make payment of the exercise price in cash or by check or in any other manner PERMITTED BY YOUR GRANT NOTICE, which may include one or more of the following: (a) In the Company's sole discretion at the time your option is exercised and provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds. (b) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, by delivery of already-owned shares of Common Stock either that you have held for the period required to avoid a charge to the Company's reported earnings (generally six months) or that you did not acquire, directly or indirectly from the Company, that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of exercise. "Delivery" for these purposes, in the sole discretion of the Company at the time you exercise your option, shall include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company. Notwithstanding the foregoing, you may 1. not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. 4. WHOLE SHARES. You may exercise your option only for whole shares of Common Stock. 5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your option must also comply with other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance with such laws and regulations. 6. TERM. You may not exercise your option before the commencement of its term or after its term expires. The term of your option commences on the Date of Grant and expires upon the earliest of the following: (a) three (3) months after the termination of your Continuous Service for any reason other than your Disability or death (or in connection with a Change in Control as provided in subsection (b) below), provided that if during any part of such three- (3-) month period your option is not exercisable solely because of the condition set forth in the preceding paragraph relating to "Securities Law Compliance," your option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; (b) twelve (12) months after the termination of your Continuous Service in connection with a Change in Control where all of the unvested shares subject to your option become fully vested and exercisable immediately prior to the effective date of such Change in Control in accordance with the provisions of Section 1 above; (c) twelve (12) months after the termination of your Continuous Service due to your Disability; (d) eighteen (18) months after your death if you die either during your Continuous Service or within three (3) months after your Continuous Service terminates; (e) the Expiration Date indicated in your Grant Notice; or (f) the day before the tenth (10th) anniversary of the Date of Grant. Notwithstanding the foregoing, if your sale of the shares acquired upon exercise of your option would subject you to suit under Section 16(b) of the Exchange Act, your option shall remain exercisable until the earlier of (i) the expiration of a period of ten (10) days after the date on which a sale of the shares by you would no longer be subject to such suit, (ii) the expiration of 2. the one hundred and ninetieth (190th) day after your termination of Continuous Service, or (iii) the Expiration Date indicated in your Grant Notice. 7. EXERCISE. (a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require. (b) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option, (2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise. 8. TRANSFERABILITY. Your option is not transferable, except (i) by will or by the laws of descent and distribution, (ii) with the prior written approval of the Company, by instrument to an inter vivos or testamentary trust, in a form accepted by the Company, in which the option is to be passed to beneficiaries upon the death of the trustor (settlor) and (iii) with the prior written approval of the Company, by gift, in a form accepted by the Company, to a permitted transferee under Rule 701 of the Securities Act. 9. OPTION NOT A SERVICE CONTRACT. Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective shareholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate. 10. WITHHOLDING OBLIGATIONS. (a) At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision as directed by the Company (including by means of a "cashless exercise" pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent directed by the Company), for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with your option. (b) The Company may, in its sole discretion, and in compliance with any applicable conditions or restrictions of law, withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in 3. excess of the minimum amount of tax required to be withheld by law. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. (c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied. Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any escrow provided for herein. 11. PARACHUTE PAYMENTS. (a) If any payment or benefit you would receive pursuant to a Change in Control from the Company or otherwise ("Payment") would (i) constitute a "parachute payment" within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the "Excise Tax"), then such Payment shall be equal to the Reduced Amount. The "Reduced Amount" shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting "parachute payments" is necessary so that the Payment equals the Reduced Amount, reduction shall occur in the following order unless you elect in writing a different order (provided, however, that such election shall be subject to Company approval if made on or after the effective date of the event that triggers the Payment): reduction of cash payments; cancellation of accelerated vesting of Stock Awards; reduction of employee benefits. In the event that acceleration of vesting of Stock Award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of your Stock Awards (i.e., earliest granted Stock Award cancelled last) unless you elect in writing a different order for cancellation. (b) The accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change in Control shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, the Company shall appoint a nationally recognized accounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder. (c) The accounting firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to you and the Company within fifteen (15) calendar days after the date on which your right to a Payment is triggered (if requested at that time by you or the Company) or such other time as requested by you or the Company. If the accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it shall 4. furnish you and the Company with an opinion reasonably acceptable to you that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the accounting firm made hereunder shall be final, binding and conclusive upon you and the Company, except as specified below. (d) If, notwithstanding any reduction described in this Section 10, the IRS determines that you are liable for the Excise Tax as a result of the receipt of the payment of benefits as described above, then you shall be obligated to pay back to the Company, within thirty (30) days after a final IRS determination or in the event that you challenge the final IRS determination, a final judicial determination, a portion of the payment equal to the "Repayment Amount." The Repayment Amount with respect to the payment of benefits shall be the smallest such amount, if any, as shall be required to be paid to the Company so that your net after-tax proceeds with respect to any payment of benefits (after taking into account the payment of the Excise Tax and all other applicable taxes imposed on such payment) shall be maximized. The Repayment Amount with respect to the payment of benefits shall be zero if a Repayment Amount of more than zero would not result in your net after-tax proceeds with respect to the payment of such benefits being maximized. If the Excise Tax is not eliminated pursuant to this paragraph, you shall pay the Excise Tax. (e) Notwithstanding any other provision of this Section 10, if (i) there is a reduction in the payment of benefits as described in this Section 10, (ii) the IRS later determines that you are liable for the Excise Tax, the payment of which would result in the maximization of your net after-tax proceeds (calculated as if your benefits had not previously been reduced), and (iii) you pay the Excise Tax, then the Company shall pay to you those benefits which were reduced pursuant to this section contemporaneously or as soon as administratively possible after you pay the Excise Tax so that your net after-tax proceeds with respect to the payment of benefits is maximized. 12. NOTICES. Any notices provided for in your option or the Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 13. GOVERNING PLAN DOCUMENT. Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of your option and those of the Plan, the provisions of the Plan shall control. 5. SGX PHARMACEUTICALS, INC.
