          10.          Exercise of Option.

                       (a)          Procedure forExercise; Rights as a Stockholder.  Any Option granted here-under 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 OptionAgreement.  Unless the Administrator provides otherwise, vesting of Options granted hereunder shall be suspended during any unpaid leave of absence.  An Option may not be exercised for a fraction of a Share.

                                     AnOption shall be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares withrespect 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 Optionshall 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 Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a dulyauthorized 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 Stock, notwithstanding the exercise of the Option.  The Company shall issue (or causeto be issued) such Shares 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 Shares are issued, except as provided in Section 12of thePlan.

                                     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 ofRelationship as a Service Provider.  If an Optionee ceases to be a Service Provider, other than upon the Optionee’s death or Disability, the Optionee may exercise his or her Option within such period of time as is specified in theOption Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement).  In the absence of a specified time in the OptionAgreement, the Option shall remain exercisable for three (3) months following the Optionee’s termination.  If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvestedportion of the Option shall revert to the Plan.  If, after termination, the Optionee does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shallrevert to the Plan.

                       (c)          Disability ofOptionee.  If an Optionee ceases to be a Service Provider as a result of the Optionee’s Disability, the Optionee may exercise his or her Option within such period of time as is specified in the Option Agreement to the extent the Optionis vested on the date of termi-nation (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement).  In the absence of a specified time in the Option Agreement, the Option shall remain exercisablefor twelve (12) months following the Optionee’s termination.  If, on the date of termina-tion, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to thePlan.  If, after termination, the Optionee does not exercise

-9-

his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

                       (d)          Death ofOptionee.  If an Optionee dies while a Service Provider, the Option may be exercised following the Optionee’s death within such period of time as is specified in the Option Agreement to the extent that the Option is vested on the dateof death (but in no event may the option be exercised later than the expiration of the term of such Option as set forth in the Option Agreement), by the Optionee’s designated beneficiary, provided such beneficiary has been designated prior toOptionee’s death in a form acceptable to the Administrator.  If no such beneficiary has been designated by the Optionee, then such Option may be exercised by the personal representative of the Optionee’s estate or by the person(s) towhom the Option is transferred pursuant to the Optionee’s will or in accordance with the laws of descent and distribution.  In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12)months following Optionee’s death.  If, at the time of death, Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall immediately revert to the Plan.  If the Option is notso exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

          11.         Stock Purchase Rights.

                       (a)          Rights toPurchase.  Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made outside of the Plan.  After the Administrator determines that it will offerStock Purchase Rights under the Plan, it shall advise the offeree in writing or electronically, by means of a Notice of Grant, of the terms, conditions and restrictions related to the offer, includ-ing the number of Shares that the offeree shall beentitled to purchase, the price to be paid, and the time within which the offeree must accept such offer.  The offer shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator.

                       (b)          RepurchaseOption.  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 service with theCompany 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 anyindebtedness of the purchaser to the Company.  The repurchase option shall lapse at a rate determined by the Administrator.

                       (c)          OtherProvisions.  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.

                       (d)          Rights as aStockholder.  Once the Stock Purchase Right is exercised, the purchaser shall have the rights equivalent to those of a stockholder, and shall be a stockholder when his or her purchase is entered upon the records of the duly authorizedtransfer 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 12 of the Plan.

                                      (i)          Transferability of Options and Stock Purchase Rights.  Unless determined otherwise by the Administrator, 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.  If the Administrator makesan Option or Stock Purchase Right transferable, such Option or Stock Purchase Right shall contain such additional terms and conditions as the Administrator deems appropriate.

          12.         Adjustments Upon Changes in Capitalization, Merger or Change in Control.

                       (a)          Changes inCapitalization.  Subject to any required action by the stockholders of the Company, the number of shares of Common Stock that have been authorized for issuance under the Plan but as to which no Options or Stock Purchase Rights have yet beengranted or which have been returned to the Plan upon cancellation or expiration of an Option or Stock Purchase Right, the number of Shares that may be added annually to the Plan pursuant to Section 3(i), and the number of shares of Common Stockas 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 stocksplit, 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 determination in that respect shallbe 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 adjust-ment by reason thereofshall be made with respect to, the number or price of shares of Common Stock subject to an Option or Stock Purchase Right.

                       (b)          Dissolution orLiquidation.  In the event of the proposed dissolution or liquida-tion of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective date of such proposed transaction.  The Administrator inits discretion may provide for an Optionee to have the right to exercise his or her Option until ten (10) days prior to such transaction as to all of the Optioned Stock covered thereby, including Shares as to which the Option would not otherwise beexercisable.  In addition, the Administrator may provide that any Company repurchase option applicable to any Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse as to all such Shares, provided the proposeddissolution or liquidation takes place at the time and in the manner contemplated.  To the extent it has not been previously exercised, an Option or Stock Purchase Right will terminate immediately prior to the consummation of such proposedaction.

                       (c)          Merger or Change inControl.  In the event of a merger of the Company with or into another corporation, or a Change in Control, each outstanding Option and Stock Purchase Right shall be assumed or an equivalent option or right substituted by the successorcorporation or a Parent or Subsidiary of the successor corporation.  ** ** 

                                      In the event that the successor corporation refuses to assume or substitute for the Option or Stock Purchase Right, the Optionee shall fully vest in and have the right to exercise the

-11-

Option or Stock Purchase Right as to all of the Optioned Stock, including Shares as to which it would not otherwise be vested or exercisable.  If an Option or StockPurchase Right becomes fully vested and exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Optionee in writing or electronically that the Option or Stock Purchase Rightshall be fully vested and exercisable for a period of fifteen (15) days from the date of such notice, and the Option or Stock Purchase Right shall terminate upon the expiration of such period.  

                                      For the purposes of this subsection (c), the Option or Stock Purchase Right shall be considered assumed if, following the merger or Change in Control, the option or right confers the right to purchase or receive, for each Share ofOptioned Stock subject to the Option or Stock Purchase Right immediately prior to the merger or Change in Control, the consideration (whether stock, cash, or other securities or property) received in the merger or Change in Control by holders ofCommon 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 ifsuch consideration received in the merger or Change in Control is 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 receivedupon 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 shareconsideration received by holders of Common Stock in the merger or Change in Control.

          13.         Date of Grant.  The date of grant of an Option or Stock Purchase Right shall be, for allpurposes, 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 Optioneewithin a reasonable time after the date of such grant.

          14.         Amendment andTermination of the Plan.

                       (c)          Effect of Amendment orTermination.  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 andsigned by the Optionee and the Company.  Termination of the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Options granted under the Plan prior to the date of suchtermination.

          15.         Conditions Upon Issuance of Shares.

                       (a)          LegalCompliance.  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

                       (b)          InvestmentRepresentations.  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 theShares 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.

          16.         Inability to Obtain Authority.  The inability of the Company to obtain authority from anyregulatory 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 orsell such Shares as to which such requisite authority shall not have been obtained.

          17.         Reservation of Shares.  The Company, during the term of this Plan, will at all times reserve andkeep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.
