(the "Plan") of the Company, which is incorporated herein by reference, as follows: 

    1.  NATURE OF THE OPTION.  This option is intended to be a non-statutory option and NOT an
incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the Code). 

    2.  OPTION PRICE.  The Option price indicated above for each share of Common Stock, is equal to the fair
market value per share of Common Stock on the date of grant of this option, as determined by the Administrator in accordance with Section 9(a) of the Plan. 

    3.  EXERCISE OF OPTION.  This option shall be exercisable in accordance with Section 11 of the

which may be obtained from the Company and shall state the election to exercise this option, the number of shares in respect of which this option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such shares of Common Stock as may be required by the Company. Such Notice of Exercise form shall be signed by the Optionee and shall be
delivered in person or by mail or by facsimile to the Company. When exercising an option, the Notice of Exercise form shall be accompanied by payment of the purchase price. Payment of the purchase

of the Optionee. 

    (iii)  RESTRICTIONS ON EXERCISE.  This option may not be exercised if the issuance of such shares upon

APPLE COMPUTER, INC. 1998

EXECUTIVE OFFICER STOCK PLAN

(as amended through 4/19/01)  

    1.  Purposes of the Plan.  The purposes of this Stock Plan are:

	to
attract and retain the best available personnel for positions of substantial responsibility;

	to
provide additional incentive to the Chairman and/or Executive Officers and other key employees; and

	•
	to
promote the success of the Company's business. 

    Options
granted under the Plan may be Incentive Stock Options (as defined under Section 422 of the Code) or Nonstatutory Stock Options, as determined by the Administrator at
the time of grant. Stock appreciation rights ("SARs") may be granted under the Plan in connection with Options or independently of Options. Stock Purchase Rights may also be granted under the Plan.

any other leave of absence approved by the Administrator, provided, in each case, that such leave does not result in termination as Chairman with the Company. Neither service as a Director nor payment
of a director's fee by the Company shall be sufficient to constitute status as "Chairman" by the Company. 

    (k) "Continuous Status as an Employee" means the absence of any interruption or termination of the employment
relationship with the Company or any Subsidiary. Continuous Status as an Employee shall not be considered interrupted in the case of (i) medical leave, military leave, family leave, or any

in termination of the employment relationship with the Company or any Subsidiary, as the case may be, under the terms of the respective Company policy for such leave; 

however, vesting may be tolled while an employee is on an approved leave of absence under the terms of the respective Company policy for such leave; or (ii) in the case of transfers between
locations of the Company or between the Company, its Subsidiaries, or its successor. For purposes of Incentive Stock Options, no such leave may exceed ninety days, unless reemployment upon expiration
of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, on the 91st day of such leave any
Incentive Stock Option held by the Optionee shall cease to be treated as an Incentive Stock Option and shall be treated for tax purposes as a Nonstatutory Stock Option. Neither service as a Chairman

    (l)  "Director" means a member of the Board.

Journal or such other source as the Administrator deems reliable; or

    3.  Stock Subject To The Plan.  Subject to the provisions of Section 15 of
the Plan, the maximum aggregate number of Shares which may be optioned and sold under the Plan or for which SARs or Stock Purchase Rights may be granted and exercised is 43,000,000 Shares. The Shares
may be authorized, but unissued, or reacquired Common Stock. 

    In
the discretion of the Administrator, any or all of the Shares authorized under the Plan may be subject to SARs issued pursuant to the Plan. 

    If
an Option, SAR or Stock Purchase Right issued under the Plan should expire or become unexercisable for any reason without having been exercised in full, the unpurchased Shares
which were subject thereto shall become available for other Options, SARs or Stock Purchase Rights under this Plan (unless the Plan has terminated); however, should the Company reacquire Shares which
were issued pursuant to the exercise of an Option or SAR, such Shares shall not become available for future grant under the Plan. If Shares of Restricted Stock are repurchased by the Company at their
original purchase price, such shares shall become available for future grant under the Plan. 

    4.  Administration of the Plan.  

    (a)  Procedure. 

     (i) Multiple Administrative Bodies. If permitted by Rule 16b-3 promulgated under the Exchange Act or
any successor rule thereto, as in effect at the time that discretion is being exercised with respect to the Plan, and by the legal requirements of the Applicable Laws relating to the administration of
stock plans such as the Plan, if any, the Plan may (but need not) be administered by different administrative bodies with respect to (A) Directors who are not Employees, (B) Directors
who are Employees, (C) Officers who are not Directors and (D) Employees who are neither Directors nor Officers. 

    (ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Options or
SARs granted hereunder as "performance-based compensation" within the meaning of Section 162(m) of the Code, the Plan shall be administered by a Committee of two or more "outside directors"
within the meaning of Section 162(m) of the Code. 

    (iii) Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under
Rule 16b-3, the transactions contemplated hereunder shall be structured to satisfy the requirements for exemption under Rule 16b-3. 

    (iv) Other Administration. Other than as provided above, the Plan shall be administered by (A) the Board or
(B) a Committee, which committee shall be constituted to satisfy 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; 

    (ii) to
select the person(s) to whom Options, SARs and Stock Purchase Rights may be granted hereunder; 

    (iii) to
determine the number of shares of Common Stock to be covered by each Option, SAR or Stock Purchase Right granted hereunder; 

    (iv) to
approve forms of agreement for use under the Plan; 

    (v) to
determine the terms and conditions, not inconsistent with the terms of the Plan, of any Option, SAR or Stock Purchase Right granted hereunder. Such terms and
conditions include, but are not limited to, the exercise price, the date of grant, the time or times when Options, SARs 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, SAR or Stock Purchase 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; 

    (vi) to
reduce the exercise price of any Option, SAR or Stock Purchase Right to the then current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option, SAR or Stock Purchase Right shall have declined since the date the Option, SAR or Stock Purchase Right was granted; 

   (vii) to
construe and interpret the terms of the Plan and awards granted pursuant to the Plan; 

   (viii) 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; 

    (ix) to
modify or amend each Option, SAR or Stock Purchase Right (subject to Section 17(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; 

    (x) to
allow Optionees to satisfy withholding tax obligations by electing to have the Company withhold from the Shares to be issued upon exercise of an Option, SAR or
Stock Purchase Right 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. All elections by an Optionee to have Shares withheld for this purpose shall be made in such form and under such conditions as the
Administrator may deem necessary or advisable; 

    (xi) to
authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Option, SAR or Stock Purchase Right previously
granted by the Administrator; and 

   (xii) 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, SARs or Stock Purchase Rights. 

    5.  Eligibility.  Nonstatutory Stock Options, SARs and Stock Purchase Rights may
be granted to the Chairman, Executive Officers and other key employees or to such other individuals as determined 

by the Administrator whom the Company has offered a position of Chairman or Executive Officer. Incentive Stock Options may be granted only to Executive Officers and other key employees. 

    6.  Limitations.  

    (a) Each
Option shall be designated in the Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to
the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Optionee during any calendar year (under all plans
of the Company and any Parent or Subsidiary) exceeds $100,000, such 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. The Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted. 

    (b) Neither
the Plan nor any Option, SAR or Stock Purchase Right shall confer upon an Optionee any right with respect to continuing the Optionee's relationship as an
Employee with or Chairman of the Company, nor shall they interfere in any way with the Optionee's right or the Company's right to terminate such relationship at any time, with or without cause. 

    (c) The
following limitations shall apply to grants of Options and SARs: 

     (i) No
participant shall be granted, in any fiscal year of the Company, Options or SARs to purchase more than 17,000,000 Shares; 

    (ii) The
foregoing limitations shall be adjusted proportionately in connection with any change in the Company's capitalization as described in Section 15; 

    (iii) If
an Option or SAR 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 15), the canceled Option will be counted against the limits set forth in subsections (i) above. For this purpose, if the exercise price of an Option or SAR is reduced, the
transaction will be treated as a cancellation of the Option or SAR and the grant of a new Option or SAR. 

    7.  Term of Plan.  Subject to Section 21 of the Plan, the Plan shall
become effective upon its adoption by the Board. It shall continue in effect for a term of ten (10) years unless terminated earlier under Section 16 of the Plan. 

    8.  Term of Option.  The term of each Option shall be stated in the Agreement. 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 Agreement. 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 total combined voting power 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 Agreement. 

    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; or 

    (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. In the case of a Nonstatutory Stock Option
intended to qualify as "performance-based compensation" within the meaning of Section 162(m) of the Code, the per Share exercise price shall be no less than 100% of the Fair Market Value per
Share on the date of grant; 

    (iii) Notwithstanding
the foregoing, Options may be granted with a per Share exercise price of less than 100% of the Fair Market Value per Share on the date of grant as
determined by the Administrator or pursuant to a merger or other corporate transaction. 

    (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. 

    (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;

    (iii) promissory
note; 

    (iv) 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 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; 

    (v) consideration
received by the Company under a cashless exercise program implemented by the Company in connection with the Plan; 

    (vi) 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; 

   (vii) any
combination of the foregoing methods of payment; or 

   (viii) such
other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws. 

    10.  Stock Appreciation Rights.  

    (a) Granted in Connection with Options. At the sole discretion of the Administrator, SARs may be granted in connection
with all or any part of an Option, either concurrently with the grant of the Option or at any time thereafter during the term of the Option. The following provisions apply to SARs that are granted in
connection with Options: 

     (i) The
SAR shall entitle the Optionee to exercise the SAR by surrendering to the Company unexercised a portion of the related Option. The Optionee shall receive in
exchange from the Company an amount equal to the excess of (x) the Fair Market Value on the date of exercise of the SAR of the Common Stock covered by the surrendered portion of the related
Option over (y) the exercise price of the Common Stock covered by the surrendered portion of the related Option. Notwithstanding the foregoing, the Administrator may place limits on the amount
that may be paid upon exercise of a SAR; provided, however, that such limit shall not restrict the exercisability of the related Option; 

    (ii) When
a SAR is exercised, the related Option, to the extent surrendered, shall no longer be exercisable; 

    (iii) A SAR shall be exercisable only when and to the extent that the related Option is exercisable and shall expire no later than the date on which the related Option
expires; and 

    (iv) A
SAR may only be exercised at a time when the Fair Market Value of the Common Stock covered by the related Option exceeds the exercise price of the Common Stock
covered by the related Option. 

    (b) Independent SARs. At the sole discretion of the Administrator, SARs may be granted without related Options. The
following provisions apply to SARs that are not granted in connection with Options: 

     (i) The
SAR shall entitle the Optionee, by exercising the SAR, to receive from the Company an amount equal to the excess of (x) the Fair Market Value of the
Common Stock covered by exercised portion of the SAR, as of the date of such exercise, over (y) the Fair Market Value of the Common Stock covered by the exercised portion of the SAR, as of the
date on which the SAR was granted; provided, however, that the Administrator may place limits on the amount that may be paid upon exercise of a SAR; and 

    (ii) SARs
shall be exercisable, in whole or in part, at such times as the Administrator shall specify in the Optionee's Agreement. 

    (c) Form of Payment. The Company's obligation arising upon the exercise of a SAR may be paid in Common Stock or in cash,
or in any combination of Common Stock and cash, as the Administrator, in its sole discretion, may determine. Shares issued upon the exercise of a SAR shall be valued at their Fair Market Value as of
the date of exercise. 

    (d) Rule 16b-3. SARs granted hereunder shall contain such additional restrictions as may be required
to be contained in the Plan or Agreement in order for the SAR to qualify for the maximum exemption provided by Rule 16b-3. 

    11.  Exercise of Option or SAR.  

    (a)  Procedure for Exercise; Rights as a Shareholder.  Any Option or SAR 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 Agreement. An Option may not be exercised for a
fraction of a Share. 

    An
Option or SAR shall be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with the terms of the Option or SAR) from the
person entitled to exercise the Option or SAR, 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 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 Shares are 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 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 15 of the Plan. 

    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. Exercise of a SAR in any manner shall, to the extent the SAR is exercised, result in a decrease in the number of Shares which thereafter shall be available for purposes
of the Plan, and the SAR shall cease to be exercisable to the extent it has been exercised. 

    (b)  Termination of Continuous Status as Chairman.  Upon termination of an Optionee's Continuous Status
as Chairman (other than termination by reason of the Optionee's death), the Optionee may, but only within ninety (90) days after the date of such termination, exercise his or 

her Option or SAR to the extent that it was exercisable at the date of such termination. Notwithstanding the foregoing, however, an Option or SAR may not be exercised after the date the Option or SAR
would otherwise expire by its terms due to the passage of time from the date of grant. 

    (c)  Termination of Continuous Employment.  Upon termination of an Optionee's Continuous Status as
Employee (other than termination by reason of the Optionee's death), the Optionee may, but only within ninety (90) days after the date of such termination, exercise his or her Option or SAR to
the extent that it was exercisable at the date of such termination. Notwithstanding the foregoing, however, an Option or SAR may not be exercised after the date the Option or SAR would otherwise
expire by its terms due to the passage of time from the date of grant. 

    (d)  Death of Optionee.  If an Optionee dies (i) while an Employee or Chairman, the Option or SAR
may be exercised at any time within six (6) months (or such other period of time not exceeding twelve (12) months as determined by the Administrator) following the date of death 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 of the right to exercise that would have accrued had the Optionee
continued living and terminated his or her employment six (6) months (or such other period of time not exceeding twelve (12) months as determined by the Administrator) after the date of
death; or (ii) within ninety (90) days after the termination of Continuous Status as an Employee or Chairman, the Option or SAR may be exercised, at any time within six (6) months
(or such other period of time not exceeding twelve (12) months as determined by the Administrator) following the date of death by the Optionee's estate or by a person who acquired the right to
exercise the Option or SAR by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the date of termination. If the Option or SAR is not so exercised within the
time specified herein, the Option or SAR shall terminate, and the Shares covered by such Option or SAR shall revert to the Plan. 

    Notwithstanding
the foregoing, however, an Option or SAR may not be exercised after the date the Option or SAR would otherwise expire by its terms due to the passage of time from the
date of grant. 

    (e)  Buyout Provisions.  The Administrator may at any time offer to buy out for a payment in cash or
Shares an Option or SAR 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. 

    12.  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 and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the
Optionee in writing or electronically, of the terms, conditions and restrictions related to the offer, including the number of Shares that the Optionee shall be entitled to purchase, the price to be
paid, and the time within which the Optionee must accept such offer. The offer shall be accepted by execution of an Agreement in the form determined by the Administrator. 

    (b)  Repurchase Option.  Unless the Administrator determines otherwise, the Agreement shall grant the
Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser's service with the Company for any reason (including death or Disability). The purchase price for
Shares repurchased pursuant to the 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)  Other Provisions.  The 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 a Shareholder.  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 15 of the Plan. 

    13.  Transferability of Options, SARs and Stock Purchase Rights.  Unless
determined otherwise by the Administrator, an Option, SAR 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 or pursuant to a qualified domestic relations order as defined by the Code or Title 1 of the Employee Retirement Income Security Act, and may be exercised, during
the lifetime of the Optionee, only by the Optionee. If the Administrator makes an Option, SAR or Stock Purchase Right
transferable, such Option, SAR or Stock Purchase Right shall contain such additional terms and conditions as the Administrator deems appropriate. 

    14.  Stock Withholding to Satisfy Withholding Tax Obligations.  When an Optionee
incurs tax liability in connection with the exercise of an Option, SAR 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 from the
Shares to be issued upon exercise of the Option, or the Shares to be issued upon exercise of the SAR or 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: 

    (c) the
election must be made on or prior to the applicable Tax Date; and 

    (d) all
elections shall be subject to the consent or disapproval of the Administrator. 

    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, SAR 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.  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, SAR or 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, SARs or Stock Purchase Rights have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, SAR or Stock Purchase Right, as well as
the price per share of Common Stock covered by each such outstanding Option, SAR 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
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, SAR or Stock Purchase
Right. 

    (b)  Dissolution or Liquidation.  In the event of the proposed dissolution or liquidation of the Company,
all outstanding Options, SARs and Stock Purchase Rights will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Administrator. The Administrator
may, in the exercise of its sole discretion in such instances, declare that any Option, SAR or Stock Purchase Right shall terminate as of a date fixed by the Administrator and give each Optionee the
right to exercise his or her Option, SAR or Stock Purchase Right as to all or any part of the Optioned Stock, including Shares as to which the Option, SAR or Stock Purchase Right would not otherwise
be exercisable. 

    (c)  Merger or Asset Sale.  Unless otherwise determined by the Administrator, 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, SAR and Stock Purchase Right shall be assumed or an equivalent
option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the
Option, SAR or Stock Purchase Right, the Optionee shall fully vest in and have the right to exercise the Option, SAR 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, SAR or Stock Purchase 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, SAR or Stock Purchase Right shall be fully vested and exercisable for a period of thirty
(30) days from the date of such notice, and the Option, SAR or Stock Purchase Right shall terminate upon the expiration of such period. For the purposes of this paragraph, the Option, SAR 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 or receive, for each Share of Optioned Stock subject to
the Option, SAR 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 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 received upon the exercise of the Option, SAR or Stock Purchase Right, for each Share of
Optioned Stock subject to the Option, SAR 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. 

    (d)  Change in Control.  In the event of a "Change in Control" of the Company, as defined in
paragraph (e) below, unless otherwise determined by the Administrator prior to the occurrence of such Change in Control, the following acceleration and valuation provisions shall apply: 

     (i) Any
Options, SARs and Stock Purchase Rights outstanding as of the date such Change in Control is determined to have occurred that are not yet exercisable and vested
on such date shall become fully exercisable and vested; and 

    (ii) The
value of all outstanding Options, SARs and Stock Purchase Rights shall, unless otherwise determined by the Administrator at or after grant, be
cashed-out. The amount at which such Options, SARs and Stock Purchase Rights shall be cashed out shall be equal to the excess of (x) the Change in Control Price (as defined below)
over (y) the exercise price of the Common Stock covered by the Option, SAR or Stock Purchase Right. The cash-out proceeds shall be paid to the Optionee or, in the event of death of
an Optionee prior to payment, to the estate of the Optionee or to a person who acquired the right to exercise the Option, SAR or Stock Purchase Right by bequest or inheritance. 

    (e)  Definition of "Change in Control".  For purposes of this Section 15, a "Change in Control"
means the happening of any of the following: 

     (i) When
any "person", as such term is used in Sections 13(d) and 14(d) of the Exchange Act (other than the Company, a Subsidiary or a Company employee benefit plan,
including any trustee of such plan acting as trustee) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the
Company representing fifty percent (50%) or more of the combined voting power of the Company's then outstanding securities; or 

    (ii) The
occurrence of a transaction requiring shareholder approval, and involving the sale of all or substantially all of the assets of the Company or the merger of
the Company with or into another corporation. 

    (f)  Change in Control Price.  For purposes of this Section 15, "Change in Control Price" shall
be, as determined by the Administrator, (i) the highest Fair Market Value at any time within the 60-day period immediately preceding the date of determination of the Change in
Control Price by the Administrator (the "60-Day Period"), or (ii) the highest price paid or offered, as determined by the Administrator, in any bona fide transaction or bona fide
offer related to the Change in Control of the Company, at any time within the 60-Day Period. 

    16.  Date of Grant.  The date of grant of an Option, SAR or Stock Purchase Right
shall be, for all purposes, the date on which the Administrator makes the determination granting such Option, SAR 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. 

    17.  Amendment and Termination of the Plan.  

    (a)  Amendment and Termination.  The Board may at any time amend, alter, suspend or terminate the Plan. 

    (b)  Shareholder Approval.  The Company shall obtain shareholder approval of any Plan amendment to the
extent necessary and desirable to comply with Applicable Laws. 

    (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.
Termination of the Plan shall not affect the Administrator's ability to exercise the powers granted to it hereunder with respect to Options, SARs or Stock Purchase Rights granted under the Plan prior
to the date of such termination. 

    18.  Conditions Upon Issuance of Shares.  

    (a)  Legal Compliance.    Shares shall not be issued pursuant to the exercise of an
Option, SAR or Stock Purchase Right unless the exercise of such Option, SAR or Stock Purchase Right and the issuance and delivery of such Shares shall comply with 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, SAR or Stock Purchase
Right, the Company may require the person exercising such Option, SAR 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. 

    19.  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. 

    20.  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. 

    21.  Shareholder Approval.  The Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months after the date the Plan is adopted. Such shareholder approval shall be obtained in the manner and to the degree required under Applicable
Laws. 

    22.  Non-U.S. Employees.  Notwithstanding anything in the Plan to the
contrary, with respect to any employee who is resident outside of the United States, the Committee may, in its sole discretion, amend the terms of the Plan in order to conform such terms with the
requirements of local law or to meet the objectives of the Plan. The Committee may, where appropriate, establish one or more sub-plans for this purpose.
