ADMINISTRATION OF THE PLAN. (a) PROCEDURE. The Plan shall be administered by the Board.

The Committee shall meet at such times and places and upon such notice as the Chairperson determines. A majority of the Committee shall constitute a quorum. Any acts by the Committee may be taken at any meeting at which a quorum is present and shall be by majority vote of those members entitled to vote. Additionally, any acts reduced to writing or approved in writing by all of the members of the Committee shall be valid acts of the Committee. (b) PROCEDURE AFTER REGISTRATION DATE. (i) ADMINISTRATION AFTER THE REGISTRATION DATE. Notwithstanding subsection (a) above, after the date of registration of the Company's Common Stock on a national securities exchange or the Registration Date, the Plan shall be administered either by: (A) the full Board, provided that all members of the Board are Disinterested Persons; or (B) a Committee of two (2) or more directors, each of whom is a Disinterested Person. After such date, the Board shall take all action necessary to administer the Plan in accordance with the then effective provisions of Rule 16b-3 promulgated under the Exchange Act, provided that any amendment to the Plan required for compliance with such provisions shall be made consistent with the provisions of Section 13 of the Plan, and said regulations. After such date, however, Options can be granted to members of the Board or the Committee only if: (X) the Plan is being administered by a Committee consisting solely of Disinterested Persons; or (Y) a majority of the Board and a majority of the Directors acting with respect to such option grants consists of Disinterested Persons. 3 (ii) ADMINISTRATION WITH RESPECT TO COVERED EMPLOYEES. Notwithstanding the foregoing, grants of Options to any Covered Employee intended to qualify as Performance-Based Compensation shall be made only by a Committee (or subcommittee of a Committee) which is comprised solely of two or more directors eligible to serve on a committee granting Options qualifying as Performance-Based Compensation. In the case of such Options granted to Covered Employees, references to the "Administrator" or to a "Committee" shall be deemed to be references to such Committee or subcommittee. (c) POWERS OF THE COMMITTEE. Subject to the provisions of the Plan, the Committee shall have the authority: (i) to determine, upon review of relevant information, the fair market value of the Common Stock; (ii) to determine the exercise price of Options to be granted, the Employees, Directors or consultants to whom and the time or times at which Options shall be granted, and the number of Shares to be represented by each Option; (iii) to interpret the Plan; (iv) to prescribe, amend and rescind rules and regulations relating to the Plan; (v) to determine the terms and provisions of each Option granted under the Plan (which need not be identical) and, with the consent of the holder thereof, to modify or amend any Option; (vi) to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of an Option previously granted by the Committee; (vii) to accelerate an exercise date of any Option subject to the provisions of Section 9(a) of the Plan; (viii) to determine whether Options granted under the Plan will be Incentive Stock Options or Nonstatutory Stock Options; and (ix) to make all other determinations deemed necessary or advisable for the administration of the Plan. (d) EFFECT OF COMMITTEE'S DECISION. All decisions, determinations and interpretations of the Committee shall be final and binding on all potential or actual Optionees, any other holder of an Option or other equity security of the Company and all other persons. 5. ELIGIBILITY. (a) PERSONS ELIGIBLE FOR OPTIONS. Options under the Plan may be granted only to Employees, Non-Employee Directors or Consultants. Incentive Stock Options may be granted only to Employees. An Employee who has been granted an Option, if he or she is otherwise eligible, may be granted an additional Option or Options. However, the aggregate fair market value (determined in accordance with the provisions of Section 8(a) of the Plan) of the Shares subject to one or more Incentive Stock Option grants that are exercisable for the first time by an Optionee during any calendar year (under all stock option plans of the Company and its Parents and Subsidiaries) shall not exceed $100,000 (determined as of the grant date). (b) NO RIGHT TO CONTINUING EMPLOYMENT. Neither the establishment nor operation of the Plan shall confer upon any Optionee or any other person any right with respect to continuation of employment or other service with the Company or any Subsidiary, nor shall the Plan interfere in any way with the right of the Optionee or other person or the right of the Company or Subsidiary to terminate such employment or service at any time. 6. TERM OF PLAN. The Plan shall become effective upon its adoption by the Board or its approval by vote of the holders of the outstanding shares of the Company entitled to vote on the adoption of the Plan (in accordance with the provisions of Section 18 hereof), whichever is earlier. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 13 of the Plan. 4 7. TERM OF OPTION. Unless the Committee determines otherwise, the term of each Option granted under the Plan shall be five (5) years from the date of grant. The term of the Option shall be set forth in the Option Agreement. No Incentive Stock Option shall be exercisable after the expiration of ten (10) years from the date such Option is granted, provided that no Incentive Stock Option granted to any Employee who, at the date such Option is granted, owns (within the meaning of Section 425(d) of the Code) more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary shall be exercisable after the expiration of five (5) years from the date such Option is granted. 8. OPTION PRICE AND CONSIDERATION. (a) OPTION PRICE. Except as provided in subsections (b) below, the option price for the Shares to be issued pursuant to any Option shall be such price as is determined by the Committee, which shall in no event be less than: (i) in the case of Incentive Stock Options, the fair market value of such Shares on the date the Option is granted; or (ii) in the case of Nonstatutory Stock Options, 85% of such fair market value; or (iii) in the case of Options intended to qualify as Performance-Based Compensation, the exercise price shall be not less than one hundred percent (100%) of the fair market value per Share on the date the Option is granted, in each case as determined by the Committee, using such criteria as it deems relevant; provided, however, that if there is a public market for the Common Stock, the fair market value per Share shall be the average of the last reported bid and asked prices of the Common Stock on the date of grant, as reported in THE WALL STREET JOURNAL (or, if not so reported, as otherwise reported by the National Association of Securities Dealers Automated Quotation (NASDAQ) System) or, in the event the Common Stock is listed on a national securities exchange (within the meaning of Section 6 of the Exchange Act), the fair market value per Share shall be the closing price on such exchange on the date of grant of the Option, as reported in THE WALL STREET JOURNAL. (b) TEN PERCENT SHAREHOLDERS. No Option shall be granted to any Employee who, at the date such Option is granted, owns (within the meaning of Section 425(d) of the Code) more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, unless the option price for the Shares to be issued pursuant to such Option is at least equal to 110 percent (110%) of the fair market value of such Shares on the grant date determined by the Committee in the manner set forth in subsection (a) above. (c) CONSIDERATION. The consideration to be paid for the Shares to be issued upon exercise of an Option shall be payment in cash or by check unless payment in some other manner, including by promissory note, other shares of the Company's Common Stock or such other consideration and method of payment for the issuance of Shares as may be permitted under Sections 408 and 409 of the California General Corporation Law, is authorized by the Committee at the time of the grant of the Option. 9. EXERCISE OF OPTION. (a) VESTING PERIOD. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Committee and as shall be permissible under the terms of the Plan, which shall be specified in the Option Agreement evidencing the Option. Unless the Committee specifically determines otherwise at the time of the grant of the Option, each 5 Option shall vest and become exercisable, cumulatively, in four substantially equal installments on each of the first four anniversaries of the date of the grant of the Option, subject to the Optionee's Continuous Employment. An Option may not be exercised for fractional shares or for less than 10 Shares. (b) INDIVIDUAL OPTION LIMIT. The maximum number of Shares with respect to which Options may be granted to any Grantee in any fiscal year of the Company shall be one million (1,000,000) Shares. The foregoing limitations shall be adjusted proportionately in connection with any change in the Company's capitalization pursuant to Section 11, below. To the extent required by Section 162(m) of the Code or the regulations thereunder, in applying the foregoing limitations with respect to an Optionee, if any Option is canceled, the canceled Option shall continue to count against the maximum number of Shares with respect to which Options may be granted to the Grantee. For this purpose, the repricing of an Option shall be treated as the cancellation of the existing Option and the grant of a new Option. (c) EXERCISE PROCEDURES. An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. After the Registration Date, in lieu of delivery of a cash payment for the purchase price of the Shares with respect to which the Option is exercised, the Optionee may deliver to the Company a sell order to a broker for the Shares being purchased and an agreement to pay (or have the broker remit payment for) the purchase price for the Shares being purchased on or before the settlement date for the sale of such shares to the broker. As soon as practicable following the exercise of an Option in the manner set forth above, the Company shall issue or cause its transfer agent to issue stock certificates representing the Shares purchased. Until the issuance of such stock certificates (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 stockholder shall exist with respect to the Optioned Shares notwithstanding the exercise of the Option. No adjustment will be made for a dividend or other rights for which the record date is prior to the date of the transfer by the Optionee of the consideration for the purchase of the Shares, except as provided in Section 11 of the Plan. (d) EXERCISE OF OPTION WITH STOCK. If an Optionee is permitted to exercise an Option by delivering shares of the Company's Common Stock, the Option Agreement covering such Option may include provisions authorizing the Optionee to exercise the Option, in whole or in part, by (i) delivering whole shares of the Company's Common Stock previously owned by such Optionee (whether or not acquired through the prior exercise of a stock option) having a fair market value equal to the Option price; or (ii) directing the Company to withhold from the Shares that would otherwise be issued upon exercise of the Option that number of whole Shares having a fair market value equal to the Option price. Shares of the Company's Common Stock so delivered or withheld shall be valued at their fair market value at the close of the last business day immediately preceding the date of exercise of the Option, as determined by the Committee. Any balance of the Option price shall be paid in cash. Any Shares delivered or withheld in accordance with this provision shall again become available for purposes of the Plan and for Options subsequently granted thereunder. After the Registration Date, any exercise of an Option under Section 9(d)(i) or 9(d)(ii) above by any person subject to short-swing trading liability under Section 16(b) of the Exchange Act shall comply with the relevant requirements of Rule 16b-3(d) or (e) promulgated under the Exchange Act. 6 (e) TERMINATION OF STATUS AS EMPLOYEE, NON-EMPLOYEE DIRECTOR OR CONSULTANT. If an Optionee shall cease to be an Employee, Non-Employee Director or Consultant for any reason other than permanent and total disability or death, he or she may, but only within 90 days (or such other period of time as is determined by the Committee) after the date he or she ceases to be an Employee, Non-Employee Director or Consultant, exercise his or her Option to the extent that he or she was entitled to exercise it at the date of such termination, subject to the condition that no Option shall be exercisable after the expiration of the Option period. In addition, any Optionee who ceases to be an Employee, Non-Employee Director or Consultant for any reason other than permanent and total disability or death who rejoins the Company as a full-time Employee within 30 days of the expiration date of his or her Option, shall maintain the unvested portion of any option which had expired in such 30-day period, with all terms other than the vesting schedule of such Option remaining unchanged for such unvested shares, and the vesting schedule adjusted forward for the amount of time elapsed between the date of such Optionee's last paycheck from the Company in his or her former position and the date of re-hire of such Optionee as a full-time Employee. (f) DISABILITY OF OPTIONEE. In the event of the permanent and total disability during the Option period of an Optionee who is at the time of such disability, or was within the 90-day period prior thereto, an Employee, Non-Employee Director or Consultant and who was in Continuous Employment as such from the date of the grant of the Option until the date of disability or termination, the Option may be exercised at any time within 90 days following the date of disability, but only to the extent of the accrued right to exercise at the time of the termination or disability, whichever comes first, subject to the condition that no option shall be exercised after the expiration of the Option period. (g) DEATH OF OPTIONEE. In the event of the death during the Option period of an Optionee who is at the time of his or her death, or was within the 90-day period immediately prior thereto, an Employee, Non-Employee Director or Consultant and who was in Continuous Employment as such from the date of the grant of the Option until the date of death or termination, the Option may be exercised, at any time within 180 days following the date of death, by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest, inheritance or otherwise as a result of the Optionee's death, but only to the extent of the accrued right to exercise at the time of the termination or death, whichever comes first, subject to the condition that no option shall be exercised after the expiration of the Option period. (h) TAX WITHHOLDING. When an Optionee is required to pay to the Company an amount with respect to tax withholding obligations in connection with the exercise of an Option granted under the Plan, the Optionee may elect, prior to the date the amount of such withholding tax is determined (the "Tax Date") to make such payment, or such increased payment as the Optionee elects to make up to the maximum federal, state and local marginal tax rates, including any related obligation under the Federal Insurance Contribution Act, applicable to the Optionee and the particular transaction, by (i) delivering cash; (ii) delivering part or all of the payment in previously owned stock (whether or not acquired through the prior exercise of a stock option); or (iii) irrevocably 7 directing the Company to withhold from the Shares that would otherwise be issued upon exercise of the Option that number of whole Shares having a fair market value equal to the amount of tax required or elected to be withheld (a "Withholding Election"). If an Optionee's Tax Date is deferred beyond the date of exercise and the Optionee makes a Withholding Election, the Optionee will receive the full amount of Shares otherwise issuable upon exercise of the Option minus the number of Shares necessary to satisfy his or her minimum withholding requirements measured on the date the Option is exercised, or such higher payment as he or she may have elected to make, with adjustments to be made in cash after the Tax Date. After the Registration Date, any withholding of Shares with respect to taxes arising in connection with the exercise of an Option by any person subject to short-swing trading liability under Section 16(b) of the Exchange Act shall satisfy the following conditions: (i) An advance election to withhold Shares in settlement of a tax liability must satisfy the requirements of Rule 16b-3(d)(1)(i), regarding participant-directed transactions; (ii) Absent such an election, the withholding of Shares to settle a tax liability may occur only during the quarterly window period described in Rule 16b-3(e); (iii) Absent an advance election or window period withholding, the Optionee may deliver Shares owned prior to the exercise of an Option to settle a tax liability arising upon exercise of the Option, in accordance with Rule 16b-3(f); or (iv) The delivery of previously acquired Shares (but not the withholding of newly acquired Shares) will be allowed where an election under Section 83(b) of the Code accelerates the Tax Date to a day that occurs less than six months after the advance election and is not within the quarterly window period described in Rule 16b-3(e). Any adverse consequences incurred by an Optionee with respect to the use of Shares to pay any part of the Option price or of any tax in connection with the exercise of an Option, including without limitation any adverse tax consequences arising as a result of a disqualifying disposition within the meaning of Section 422 of the Code, shall be the sole responsibility of the Optionee. 10. NON-TRANSFERABILITY OF OPTIONS. An Option may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent and distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. 11. ADJUSTMENTS UPON 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 the per share exercise price thereof in each such Option, 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, combination, reclassification, the payment of a stock dividend on the Common Stock or any other increase or decrease in the number of such shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the 8 Company shall not be deemed to have been "effected without receipt of consideration". Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issue 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. The Committee may, if it so determines in the exercise of its sole discretion, also make provision for adjusting the number or class of securities covered by any Option, as well as the price to be paid therefor, in the event that the Company effects one or more reorganizations, recapitalizations, rights offerings, or other increases or reductions of shares of its outstanding Common Stock, and in the event of the Company being consolidated with or merged into any other corporation. Unless otherwise determined by the Board, upon the dissolution or liquidation of the Company the Options granted under the Plan shall terminate and thereupon become null and void. Upon any merger or consolidation, if the Company is not the surviving corporation, the Options granted under the Plan shall either be assumed by the new entity or shall terminate in accordance with the provisions of the preceding sentence. 12. TIME OF GRANTING OPTIONS. Unless otherwise specified by the Committee, the date of grant of an Option under the Plan shall be the date on which the Committee makes the determination granting such Option. Notice of the determination shall be given to each Employee to whom an Option is so granted within a reasonable time after the date of such grant. 13. AMENDMENT AND TERMINATION OF THE PLAN. The Board may amend or terminate the Plan from time to time in such respects as the Board may deem advisable, except that, without approval of the shareholders of the Company, no such revision or amendment shall change the number of Shares subject to the Plan, change the designation of the class of employees eligible to receive Options or add any material benefit to Optionees under the Plan. Any such amendment or termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if the Plan had not been amended or terminated. 14. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued with respect to an Option granted under the Plan unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a condition to the exercise of an Option, the Company may require the person exercising such Option 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 by any of the aforementioned relevant provisions of law. 9 15. RESERVATION OF SHARES. During the term of this Plan the Company will at all times reserve and keep available the number of Shares as shall be sufficient to satisfy the requirements of the Plan. Inability of the Company to obtain from any regulatory body having jurisdiction and authority 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 non-issuance or sale of such Shares as to which such requisite authority shall not have been obtained. 16. INFORMATION TO OPTIONEE. During the term of any Option granted under the Plan, the Company shall provide or otherwise make available to each Optionee a copy of its annual report to Shareholders and financial information which is provided to its shareholders in accordance with the provisions of the Company's Bylaws and applicable law. 17. OPTION AGREEMENT. Options granted under the Plan shall be evidenced by Option Agreements. 18. SHAREHOLDER APPROVAL. The Plan was approved by the shareholders of the Company within twelve (12) months after the Plan having been adopted by the Board. Any amendments to the Plan which require shareholder approval shall be by the affirmative vote of the holders of a majority of the outstanding capital stock represented and voting at a duly held meeting or by the written consent of shareholders. 10
