(b) The stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. 5. ELIGIBILITY. Options may be granted only to Employees who, at the time of grant, are working or residing outside of the United States and are not Officers or Directors. 6. OPTION PROVISIONS. Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of separate Options need not be identical, but 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 twelve (12) years from the date it was granted. (b) Price. Unless otherwise provided expressly by the Board or Committee, the per share exercise price of each Option shall not be less than eighty-five percent (85%) of the Fair Market Value of a share of the Company's Common Stock on the date of grant. (c) Consideration. The purchase price of stock acquired pursuant to exercise of an Option shall be paid, to the extent permitted by applicable statutes and regulations, either (i) in cash at the time the Option is exercised, or (ii) at the discretion of the Board or the Committee, at the time of the grant of the Option, (A) by delivery to the Company of other common stock of the Company, (B) according to a deferred payment or other arrangement (which may include, without limiting the generality of the foregoing, the use of other common stock of the Company) with the person to whom the Option is granted or to whom the Option is transferred pursuant to subsection 6(d), or (C) in any other form of legal consideration that may be acceptable to the Board. In the case of any deferred payment arrangement, interest shall be compounded at least annually and shall be charged at the minimum rate of interest necessary to avoid (1) the treatment as interest, under any applicable provisions of the Code, of any amounts other than amounts stated to be interest under the deferred payment arrangement and (2) the treatment of the Option as a variable award for financial accounting purposes. (d) Transferability. In the absence of a provision on transferability in an Option Agreement, a Nonstatutory Stock Option shall not be transferable except by will or by the laws of descent and distribution or pursuant to a domestic relations order satisfying the requirements of Rule 16b-3 and the rules thereunder (a "DRO"), and shall be exercisable during the lifetime of the person to whom the Option is granted only by such person or any transferee pursuant to a DRO. The person to whom a Nonstatutory Stock Option is granted may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionee, shall thereafter be entitled to exercise the Nonstatutory Stock Option. (e) Vesting. The total number of shares of stock subject to an Option may, but need not, be allotted in periodic installments (which may, but need not, be equal). The Option Agreement may provide that from time to time during each of such installment periods, the Option may become exercisable ("vest") with respect to some or all of the shares allotted to that period, and may be exercised with respect to some or all of the shares allotted to such period and/or any prior period as to which the Option became vested but was not fully exercised. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may deem appropriate. The provisions of this subsection 6(e) are subject to any Option provisions governing the minimum number of shares as to which an Option may be exercised. (f) Investment Assurances. The Company may require any Optionee, or any person to whom an Option is transferred under subsection 6(d), as a condition of exercising any such Option, (1) to give written assurances satisfactory to the Company as to the Optionee'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 (2) to give written assurances satisfactory to the Company stating that such person is acquiring the stock subject to the Option for such person's own account and not with any present intention of selling or otherwise distributing the stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (i) the issuance of the shares upon the exercise of the Option has been registered under a then currently effective registration statement under the Securities Act of 1933, as amended (the "Securities Act"), or (ii) 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 stock. (g) Termination of Employment or Relationship as a Director or Consultant. In the event an Optionee's Continuous Status as an Employee, Director or Consultant terminates (other than upon the Optionee's death or disability), the Optionee may exercise his or her Option (to the extent that the Optionee was entitled to exercise it at the date of termination) but only within such period of time ending on the earlier of (i) the date three (3) months after the termination of the Optionee's Continuous Status as an Employee, Director or Consultant, or such longer or shorter period specified in the Option Agreement, or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionee does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate, and the shares covered by such Option shall revert to and again become available for issuance under the Plan. (h) Disability of Optionee. In the event an Optionee's Continuous Status as an Employee, Director or Consultant terminates as a result of the Optionee's disability, the Optionee may exercise his or her Option (to the extent that the Optionee was entitled to exercise it at the date of termination), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such termination (or such longer or shorter period specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, at the date of termination, the Optionee is not entitled to exercise his or her entire Option, the shares covered by the unexercisable portion of the Option shall revert to and again become available for issuance under the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the shares covered by such Option shall revert to and again become available for issuance under the Plan. (i) Death of Optionee. In the event of the death of an Optionee during, or within a period specified in the Option after the termination of, the Optionee's Continuous Status as an Employee, Director or Consultant, the Option may be exercised (to the extent the Optionee was entitled to exercise the Option at the date of death) by the Optionee's estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the option upon the Optionee's death pursuant to subsection 6(d), but only within the period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Option Agreement), or (ii) the expiration of the term of such Option as set forth in the Option Agreement. If, at the time of death, the Optionee was not entitled to exercise his or her entire Option, the shares covered by the unexercisable portion of the Option shall revert to and again become available for issuance under the Plan. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate, and the shares covered by such Option shall revert to and again become available for issuance under the Plan. (j) Early Exercise. The Option may, but need not, include a provision whereby the Optionee may elect at any time while an Employee, Director or Consultant to exercise the Option as to any part or all of the shares subject to the Option prior to the full vesting of the Option. Any unvested shares so purchased may be subject to a repurchase right in favor of the Company or to any other restriction the Board determines to be appropriate. (k) Withholding. To the extent provided by the terms of an Option Agreement for an Option, the Participant may satisfy any federal, state, local, or other tax withholding obligation relating to the exercise of such Option by any of the following means (in addition to the Company's right to withhold from any compensation paid to the Optionee by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the Company to withhold shares of common stock from the shares of common stock otherwise issuable to the Optionee as a result of the exercise of the Option; provided, however, that no shares of common stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such lesser amount as may be necessary to avoid variable award accounting); or (iii) delivering to the Company owned and unencumbered shares of common stock. 7. COVENANTS OF THE COMPANY. (a) During the terms of the Options, the Company shall keep available at all times the number of shares of stock required to satisfy such Options. (b) The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell shares of stock upon exercise of the Options; provided, however, that this undertaking shall not require the Company to register under the Securities Act either the Plan, any Option or any 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 stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such Options unless and until such authority is obtained. 8. USE OF PROCEEDS FROM STOCK. Proceeds from the sale of stock pursuant to Options shall constitute general funds of the Company. 9. MISCELLANEOUS. (a) 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 or any part thereof will vest pursuant to subsection 6(e), notwithstanding the provisions in the Option stating the time at which it may first be exercised or the time during which it will vest. (b) Neither an Optionee nor any person to whom an Option is transferred under subsection 6(d) shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to such Option unless and until such person has satisfied all requirements for exercise of the Option pursuant to its terms. (c) Nothing in the Plan or any instrument executed or Option granted pursuant thereto shall confer upon any Employee, Director, Consultant or Optionee any right to continue in the employ of the Company or any Affiliate (or to continue acting as a Director or Consultant) or shall affect the right of the Company or any Affiliate to terminate the employment or relationship as a Director or Consultant of any Employee, Director, or Consultant for any reason, with or without cause. 10. ADJUSTMENTS UPON CHANGES IN STOCK. (a) If any change is made in the stock subject to the Plan, or subject to any Option (through merger, consolidation, reorganization, recapitalization, 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), the Plan will be appropriately adjusted in the types of securities and maximum number of shares subject to the Plan pursuant to subsection 4(a), and the outstanding Options will be appropriately adjusted in the types of securities and number of shares and price per share of stock subject to such outstanding Options. (b) In the event of: (1) a dissolution, liquidation or sale of substantially all of the assets of the Company; (2) a merger or consolidation in which the Company is not the surviving corporation; or (3) a reverse merger in which the Company is the surviving corporation but the shares of the Company's common stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, then to the extent permitted by applicable law: (i) any surviving corporation shall either assume any Options outstanding under the Plan or shall substitute similar Options for those outstanding under the Plan, or (ii) such Options shall terminate to the extent not exercised prior to such event; provided, however, that the time during which some or all of such Options may be exercised may, at the discretion of the Board, be accelerated to prior to such event. 11. AMENDMENT OF THE PLAN AND OPTIONS. (a) The Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 10 relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the stockholders of the Company within twelve (12) months before or after the adoption of the amendment, where the amendment will modify the Plan in any way (including, but not limited to, the modification of the eligibility requirements for participation in the Plan) if such modification requires stockholder approval in order for the Plan to comply with any NASDAQ or securities exchange listing requirements. (b) The Board may in its sole discretion submit any other amendment to the Plan for stockholder approval. (c) It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide Optionees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Options and/or to bring the Plan and/or Options granted under it into compliance therewith. (d) Rights and obligations under any Option granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the person to whom the Option was granted and (ii) such person consents in writing. (e) Subject to the provisions of Section 13 hereof, the Board at any time, and from time to time, may amend the terms of any one or more Options; provided, however, that the rights and obligations under any Option shall not be impaired by any such amendment unless (i) the Company requests the consent of the person to whom the Option was granted and (ii) such person consents in writing. 12.
