(iii) Administration With Respect to Other Persons. With respect to Option or Stock Purchase Right grants made to Employees or Consultants who are neither Directors nor Officers of the Company, the Plan shall be administered by (A) the Board or (B) a committee designated by the Board, which committee shall be constituted to satisfy Applicable Laws. Once appointed, such Committee shall serve in its designated capacity until otherwise directed by the Board. The Board may increase the size of the Committee and appoint additional members, remove members (with or without cause) and substitute new members, fill vacancies (however caused), and remove all members of the Committee and thereafter directly administer the Plan, all to the extent permitted by Applicable Laws. (b) Powers of the Administrator. Subject to the provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion: (i) to determine the Fair Market Value of the Common Stock, in accordance with Section 2(n) of the Plan; (ii) to select the Consultant, Directors and Employees to whom Options and Stock Purchase Rights may be granted hereunder; (iii) to determine whether and to what extent Options and Stock Purchase Rights or any combination thereof, are granted hereunder; (iv) to determine the number of shares of Common Stock to be covered by each Option and Stock Purchase Right granted hereunder; (v) to approve forms of agreement for use under the Plan; (vi) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any award granted hereunder. Such terms and conditions include, but are not limited to, the exercise price, the time or times when Options or Stock Purchase Rights may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Option or Stock Purchase <PAGE> 6 Right or the shares of Common Stock relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall determine; (vii) to reduce the exercise price of any Option or Stock Purchase Right to the then current Fair Market Value if the Fair Market Value of the Common Stock covered by such Option or Stock Purchase Right shall have declined since the date the Option or Stock Purchase Right was granted; (viii) to construe and interpret the terms of the Plan and awards granted pursuant to the Plan; (ix) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of qualifying for preferred tax treatment under foreign tax laws; (x) to modify or amend each Option or Stock Purchase Right (subject to Section 18(c) of the Plan), including the discretionary authority to extend the post-termination exercisability period of Options longer than is otherwise provided for in the Plan: (xi) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Option or Stock Purchase Right previously granted by the Administrator; (xii) to institute an Option Exchange Program; (xiii) to determine the terms and restrictions applicable to Options and Stock Purchase Rights and any Restricted Stock; and (xiv) to make all other determinations deemed necessary or advisable for administering the Plan. (c) Effect of Administrator's Decision. The Administrator's decisions, determinations and interpretations shall be final and binding on all Optionees and any other holders of Options or Stock Purchase Rights. 5. Eligibility. Nonstatutory Stock Options and Stock Purchase Rights may be granted to Employees, Directors and Consultants. Incentive Stock Options may be granted only to Employees. If otherwise eligible, an Employee, Director or Consultant who has been granted an Option or Stock Purchase Right may be granted additional Options or Stock Purchase Rights. 6. Limitations. (a) Each Option shall be designated in the Notice of Grant as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designations, to the extent that the aggregate Fair Market Value: (i) of Shares subject to an Optionee's Incentive Stock Options granted by the Company, any Parent or Subsidiary, which <PAGE> 7 (ii) become exercisable for the first time during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the time of grant. (b) Neither the Plan nor any Option or Stock Purchase Right shall confer upon an Optionee any right with respect to continuing the Optionee's employment or consulting relationship with the Company, nor shall they interfere in any way with the Optionee's right or the Company's right to terminate such employment or consulting relationship at any time, with or without cause. (c) The following limitations shall apply to grants of Options and Stock Purchase Rights to Employees: (i) No Employee shall be granted, in any fiscal year of the Company, Options and Stock Purchase Rights to purchase more than 700,000 Shares; provided, however, that the foregoing limitation shall not apply prior to the Public Trading Date and, following the Public Trading Date, the foregoing limitation shall not apply until the earliest of: (i) the first material modification of the Plan (including any increase in the number of shares reserved for issuance under the Plan in accordance with Section 3); (ii) the issuance of all of the shares of Common Stock reserved for issuance under the Plan; (iii) the expiration of the Plan; (iv) the first meeting of stockholders at which Directors of the Company are to be elected that occurs after the close of the third calendar year following the calendar year in which occurred the first registration of an equity security of the Company under Section 12 of the Exchange Act; or (v) such other date required by Section 162(m) of the Code and the rules and regulations promulgated thereunder. The foregoing limitation shall be adjusted proportionately in connection with any change in the Company's capitalization as described in Section 16. For purposes of this Section 6(c), if an Option is canceled in the same calendar year it was granted (other than in connection with a transaction described in Section 16), the canceled Option will be counted against the limit set forth in this Section 6(c). For this purpose, if the exercise price of an Option is reduced, the transaction shall be treated as a cancellation of the Option and the grant of a new Option. (ii) The foregoing limitations shall be adjusted proportionately in connection with any change in the Company's capitalization as described in Section 16. (iii) If an Option or Stock Purchase Right is canceled in the same fiscal year of the Company in which it was granted (other than in connection with a transaction described in Section 16), the canceled Option or Stock Purchase Right will be counted against the limit set forth in Section 6(c)(i). For this purpose, if the exercise price of an Option or Stock Purchase Right is reduced, the transaction will be treated as a cancellation of the Option or Stock Purchase Right and the grant of a new Option or Stock Purchase Right. 7. Term of Plan. Subject to Section 22 of the Plan, the Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the shareholders of the <PAGE> 8 Company as described in Section 22 of the Plan. It shall continue in effect for a term of ten (10) years unless terminated earlier under Section 18 of the Plan. 8. Term of Option. The term of each Option shall be stated in the Notice of Grant; provided, however, that in the case of an Incentive Stock Option, the term shall be ten (10) years from the date of grant or such shorter term as may be provided in the Notice of Grant. Moreover, in the case of an Incentive Stock Option granted to an Optionee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the voting of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option shall be five (5) years from the date of grant or such shorter term as may be provided in the Notice of Grant. 9. Option Exercise Price and Consideration. (a) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option shall be determined by the Administrator, subject to the following: (i) In the case of an Incentive Stock Option (A) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. (B) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant. (ii) In the case of a Nonstatutory Stock Option, the per Share exercise price shall be determined by the Administrator, but shall in no event be less than the par value per Share. (b) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator shall fix the period within which the Option may be exercised and shall determine any conditions which must be satisfied before the Option may be exercised. In so doing, the Administrator may specify that an Option may not be exercised until the completion of a service period. (c) Form of Consideration. The Administrator shall determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator shall determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely of: (i) cash; (ii) check; <PAGE> 9 (iii) money order; (iv) promissory note; (v) other Shares which (A) in the case of Shares acquired upon exercise of an option, have been owned by the Optionee for more than six (6) months on the date of surrender, and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised; (vi) delivery of a properly executed exercise notice together with such other documentation as the Administrator and the broker, if applicable, shall require to effect an exercise of the Option and delivery to the Company of the sale or loan proceeds required to pay the exercise price; (vii) a reduction in the amount of any Company liability to the Optionee, including any liability attributable to the Optionee's participation in any Company-sponsored deferred compensation program or arrangement; (viii) any combination of the foregoing methods of payment; or (ix) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws. 10. Exercise of Option. (a) Procedure for Exercise: Rights as a Stockholder. Any Option granted hereunder shall be exercisable according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Option Agreement. An Option may not be exercised for a fraction of a Share. An Option shall be deemed exercised when the Company receives: (i) written notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Optionee or, if requested by the Optionee, in the name of the Optionee and his or her spouse. Until the stock certificate evidencing such Shares is issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such stock certificate promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 16 of the Plan. <PAGE> 10 Exercising an Option in any manner shall decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. (b) Termination of Employment, Directorship or Consulting Relationship. Upon termination of an Optionee's Continuous Status as an Employee, Director or Consultant (but not in the event of a change of status from Employee to Consultant (in which case an Employee's Incentive Stock Option shall automatically convert to a Nonstatutory Stock Option on the ninety-first (91st) day following such change of status) or from Consultant to Employee), other than upon the Optionee's death or Disability, the Optionee may exercise his or her Option, but only within such period of time as is specified in the Notice of Grant, and only to the extent that the Optionee was entitled to exercise it at the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant). In the absence of a specified time in the Notice of Grant, the Option shall remain exercisable for thirty (30) days following the Optionee's termination of Continuous Status as an Employee, Director or Consultant. In the case of an Incentive Stock Option, such period of time shall not exceed ninety (90) days from the date of termination. 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 the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. (c) Disability of Optionee. Notwithstanding the provisions of Section 10(b) above, in the event of termination of an Optionee's Consulting relationship or Continuous Status as an Employee or Director as a result of his Disability then the period during which each outstanding option held by the Optionee is to remain exercisable shall be limited to the six (6)-month period following the date of such cessation of service. However, should such Disability be deemed to constitute Permanent Disability, then the period during which each outstanding option held by the Optionee is to remain exercisable shall be extended by an additional six (6) months so that the exercise period shall be limited to the twelve (12)-month period following the date of the Optionee's cessation of Service by reason of such Permanent Disability. For the purposes of the Plan, Disability shall be determined by the Administrator on the basis of such medical evidence as the Administrator deems warranted under the circumstances. For purposes of the Plan, Disability shall be deemed to constitute Permanent Disability in the event that such Disability is expected to result in death or has lasted or can be expected to last for a continuous period of not less than twelve (12) months. (d) Death of Optionee. In the event of the death of an Optionee, the Option may be exercised at any time within twelve (12) months (or such other period of time as is determined by the Administrator, with such determination in the case of an Incentive Stock Option being made at the time of grant of the Option) following the date of death (but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant), by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent that the Optionee was entitled to exercise the Option at the date of death. 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 immediately revert to the Plan. If, after death, the Optionee's estate or a person who acquired the right to exercise <PAGE> 11 the Option by bequest or inheritance does not exercise the Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. (e) Rule 16b-3. Options granted to individuals subject to Section 16 of the Exchange Act ("Insiders") must comply with the applicable provisions of Rule 16b-3 and shall contain such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. (f) Buyout Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares, an Option previously granted, based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made. 11. Granting of Options to Independent Directors. During the term of the Plan, a person who is an Independent Director as of the Public Trading Date (an "IPO Independent Director") and has not previously received an Option grant automatically shall be granted an Option to purchase 24,000 shares of Common Stock on the date of such consummation (an "IPO Option"). IPO Independent Directors and a person who becomes an Independent Director after the Public Trading Date automatically shall be granted an Option to purchase 8000 shares of Common Stock (subject to adjustment as provided in Section 16) on the date of each annual meeting of stockholders after the Public Trading Date (a "Post-IPO Option"). Members of the Board who are employees of the Company who subsequently retire from the Company and remain on the Board will not receive an IPO Option grant, but to the extent they are otherwise eligible, will receive, after retirement from employment with the Company, Post-IPO Options. All the foregoing Option grants authorized by this Section 11 are subject to stockholder approval of the Plan. 12. Terms of Options Granted to Independent Directors. The per Share price of each Option granted to an Independent Director shall equal 100% of the Fair Market Value of a share of Common Stock on the date the Option is granted; provided, however, that the per Share price of each Option granted to an Independent Director on the date of the initial public offering of Common Stock shall equal the initial public offering price per Share (as determined by the Pricing Committee of the Board in its sole and absolute discretion. IPO Options (as defined in Section 11) granted to Independent Directors shall become exercisable in cumulative quarterly installments of 1/12 of the Shares subject to such option on each of the quarterly anniversaries of the date of IPO Option grant, commencing with the first such quarterly anniversary, such that each IPO Option shall be one hundred percent (100%) vested on the third anniversary of its date of grant. Post-IPO Options (as defined in Section 11) granted to Independent Directors shall become vested in cumulative quarterly installments of 1/4 of the Shares subject to such Option on each of the quarterly anniversaries of the date of Post-IPO Option grant, commencing with the ninth quarterly anniversary of such date of Post-IPO Option grant, such that each Post-IPO Option shall be one hundred percent (100%) vested on the third anniversary of the date of Post-IPO Option grant. Subject to Section 10, the term of each Option granted to an Independent Director shall be ten (10) years from the date the Option is granted. No portion of an Option which is unexercisable at the time of an Independent Director's termination of membership on the Board shall thereafter become exercisable. <PAGE> 12 13. Stock Purchase Rights. (a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted under the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing, by means of a Notice of Grant, of the terms, conditions and restrictions related to the offer, including the number of Shares that the offeree shall be entitled to purchase, the price to be paid, and the time within which the offeree must accept such offer, which shall in no event exceed thirty (30) days from the date upon which the Administrator made the determination to grant the Stock Purchase Right. The offer shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator. (b) Repurchase Option. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser's Continuous Status as an Employee, Director or Consultant with the Company for any reason (including death or Disability). The purchase price for Shares repurchased pursuant to the Restricted Stock purchase agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at a rate determined by the Administrator. (c) Rule 16b-3. Stock Purchase Rights granted to Insiders, and Shares purchased by Insiders in connection with Stock Purchase Rights, shall be subject to any restrictions applicable thereto in compliance with Rule 16b-3. An Insider may only purchase Shares pursuant to the grant of a Stock Purchase Right, and may only sell Shares purchased pursuant to the grant of a Stock Purchase Right, during such time or times as are permitted by Rule 16b-3. (d) Other Provisions. The Restricted Stock Purchase Agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion including but not limited to the per Share purchase price, which shall in no event be less than the par value per Share. In addition, the provisions of Restricted Stock Purchase Agreements need not be the same with respect to each purchaser. (e) Rights as a Stockholder. Once the Stock Purchase Right is exercised, the purchaser shall have the rights equivalent to those of a shareholder, and shall be a shareholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 16 of the Plan. 14. Stock Withholding to Satisfy Withholding Tax Obligations. At the discretion of the Administrator, Optionees may satisfy withholding obligations as provided in this paragraph. When an Optionee incurs tax liability in connection with an Option or Stock Purchase Right, which tax liability is subject to tax withholding under applicable tax laws, and the Optionee is obligated to pay the Company an amount required to be withheld under applicable tax laws, the Optionee may satisfy the withholding tax obligation by electing to have the Company withhold <PAGE> 13 from the Shares to be issued in connection with the Stock Purchase Right, if any, that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined (the "Tax Date"). All elections by an Optionee to have Shares withheld for this purpose shall be made in writing in a form acceptable to the Administrator and shall be subject to the following restrictions: (a) the election must be made on or prior to the applicable Tax Date; (b) once made, the election shall be irrevocable as to the particular Shares of the Option or Right as to which the election is made; (c) all elections shall be subject to the consent or disapproval of the Administrator; (d) if the Optionee is subject to Rule 16b-3, the election must comply with the applicable provisions of Rule 16b-3 and shall be subject to such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. In the event the election to have Shares withheld is made by an Optionee and the Tax Date is deferred under Section 83 of the Code because no election is filed under Section 83(b) of the Code, the Optionee shall receive the full number of Shares with respect to which the Option or Stock Purchase Right is exercised but such Optionee shall be unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date. 15. Non-Transferability of Options and Stock Purchase Rights. An Option or Stock Purchase Right may not be sold, pledged, assigned, hypothecated, transferred, or disposed 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. 16. Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset Sale. (a) Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option and Stock Purchase Right, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options or Stock Purchase Rights have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option or Stock Purchase Right, as well as the price per share of Common Stock covered by each such outstanding Option or Stock Purchase Right, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been effected without receipt of consideration. Such adjustment shall be made by the Board, whose <PAGE> 14 determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option or Stock Purchase Right. (b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Board shall notify the Optionee at least fifteen (15) days prior to such proposed action. To the extent it has not been previously exercised, the Option or Stock Purchase Right will terminate immediately prior to the consummation of such proposed action. (c) Merger or Asset Sale. In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the assets of the Company, each outstanding Option and Stock Purchase Right may be assumed or an equivalent option or right may be substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. The Administrator may, in lieu of such assumption or substitution, provide for the Optionee to have the right to exercise the Option or Stock Purchase Right as to all or a portion of the Optioned Stock, including Shares as to which it would not otherwise be exercisable. If the Administrator makes an Option or Stock Purchase Right exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Optionee that the Option or Stock Purchase Right shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and the Option or Stock Purchase Right will terminate upon the expiration of such period. For the purposes of this paragraph, the Option or Stock Purchase Right shall be considered assumed if, following the merger or sale of assets, the option or right confers the right to purchase, for each Share of Optioned Stock subject to the Option or Stock Purchase Right immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or sale of assets was not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option or Stock Purchase Right, for each Share of Optioned Stock subject to the Option or Stock Purchase Right, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the merger or sale of assets. 17. Date of Grant. The date of grant of an Option or Stock Purchase Right shall be, for all purposes, the date on which the Administrator makes the determination granting such Option or Stock Purchase Right, or such other later date as is determined by the Administrator. Notice of the determination shall be provided to each Optionee within a reasonable time after the date of such grant. 18. Amendment and Termination of the Plan. (a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. <PAGE> 15 (b) Stockholder Approval. The Company shall obtain shareholder approval of any Plan amendment to the extent necessary and desirable to comply with Rule 16b-3 or with Section 422 of the Code (or any successor rule or statute or other applicable law, rule or regulation, including the requirements of any exchange or quotation system on which the Common Stock is listed or quoted). Such shareholder approval, if required, shall be obtained in such a manner and to such a degree as is required by the applicable law, rule or regulation. (c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan shall impair the rights of any Optionee, unless mutually agreed otherwise between the Optionee and the Administrator, which agreement must be in writing and signed by the Optionee and the Company. 19. Conditions Upon Issuance of Shares. (a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Option or Stock Purchase Right unless the exercise of such Option or Stock Purchase Right and the issuance and delivery of such Shares shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and Applicable Laws, and shall be further subject to the approval of counsel for the Company with respect to such compliance. (b) Investment Representations. As a condition to the exercise of an Option or Stock Purchase Right, the Company may require the person exercising such Option or Stock Purchase Right to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required. 20. Liability of Company. (a) Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. (b) Grants Exceeding Allotted Shares. If the Optioned Stock covered by an Option or Stock Purchase Right exceeds, as of the date of grant, the number of Shares which may be issued under the Plan without additional shareholder approval, such Option or Stock Purchase Right shall be void with respect to such excess Optioned Stock, unless shareholder approval of an amendment sufficiently increasing the number of Shares subject to the Plan is timely obtained in accordance with Section 18(b) of the Plan. 21. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 22. Stockholder Approval. Continuance of the Plan shall be subject to approval by the shareholders of the Company within twelve (12) months before or after the date the Plan is <PAGE> 16 adopted. Such shareholder approval shall be obtained in the manner and to the degree required under applicable federal and state law. 23. Governing Law. The validity and enforceability of this Plan shall be governed by and construed in accordance with the laws of the State of Delaware without regard to otherwise governing principles of conflicts of law.
