                           ART TECHNOLOGY GROUP, INC.

                              AMENDED AND RESTATED
                     1999 OUTSIDE DIRECTOR STOCK OPTION PLAN

1.       Purpose

         The purpose of this Amended and Restated 1999 Outside Director Stock
Option Plan (the "Plan") of Art Technology Group, Inc., a Delaware corporation
(the "Company"), is to advance the interests of the Company's stockholders by
enhancing the Company's ability to attract, retain and motivate outside
directors of the Company by providing such directors with equity ownership
opportunities and performance-based incentives and thereby better aligning the
interests of such persons with those of the Company's stockholders.

2.       Eligibility

         Each director of the Company who is not an employee of the Company (an
"Eligible Director") is eligible to be granted options (an "Option") under the
Plan. Any person who has been granted an Option under the Plan shall be deemed a
"Participant."

3.       Administration, Delegation

         The Plan will be administered by the Board of Directors of the Company
(the "Board"). The Board shall have authority to adopt, amend and repeal such
administrative rules, guidelines and practices relating to the Plan as it shall
deem advisable. The Board may correct any defect, supply any omission or
reconcile any inconsistency in the Plan or any Option in the manner and to the
extent it shall deem expedient to carry the Plan into effect and it shall be the
sole and final judge of such expediency. All decisions by the Board shall be
made in the Board's sole discretion and shall be final and binding on all
persons having or claiming any interest in the Plan or in any Option. No
director or person acting pursuant to the authority delegated by the Board shall
be liable for any action or determination relating to or under the Plan made in
good faith.

4.       Stock Available for Options

         a. Number of Shares. Subject to adjustment under Section 4(b), Options
may be made under the Plan for up to 800,000 shares of common stock, $.01 par
value per share, of the Company (the "Common Stock"). If any Option expires or
is terminated, surrendered or canceled without having been fully exercised or is
forfeited in whole or in part or results in any Common Stock not being issued,
the unused Common Stock covered by such Option shall again be available for the
grant of Options under the Plan. Shares issued under the Plan may consist in
whole or in part of authorized but unissued shares or treasury shares.

         b. Adjustment to Common Stock. In the event of any stock split, stock
dividend, recapitalization, reorganization, merger, consolidation, combination,
exchange of shares, liquidation, spin-off or other similar change in
capitalization or event, or any distribution to holders of Common Stock other
than a normal cash dividend, (i) the number and class of securities available
under this Plan, (ii) the number and class of securities and exercise price per
share subject to each outstanding Option, and (iii) the number and class of
securities available for automatic grants shall be appropriately adjusted by the
Company (or substituted Options may be made, if applicable) to the extent the
Board shall determine, in good faith, that such an adjustment (or substitution)
is necessary and appropriate. If this Section 4(b) applies and Section 6(c) also
applies to any event, Section 6(c) shall be applicable to such event, and this
Section 4(b) shall not be applicable.

5.       Stock Options

         a. Grants. The Board may grant Options and determine the number of
shares of Common Stock to be covered by each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. None of the Options granted hereunder are intended to be
Incentive Stock Options as defined in Section 422 of the Internal Revenue Code
of 1986, as amended, and any regulations promulgated thereunder.

         b. Option Exercise Price. The option exercise price per share for each
Option granted under the Plan shall equal (i) the last reported sales price per
share of the Company's Common Stock as listed on a nationally recognized
securities exchange or the Nasdaq National Market, as the case may be, on the
date of grant (or, if no such price is reported on such date, such price as
reported on the nearest preceding day); or (ii) the fair market value of the
stock on the date of grant, as determined by the Board of Directors, if the
Common Stock is not publicly traded. Notwithstanding the preceding sentence, the
option exercise price per share for each Option granted as of the Effective Date
of the initial public offering shall be the price per share for which the Common
Stock was offered to the public.

         c.       Exercise Period. No Option may be exercised more than one year
after the Participant ceases to serve as a director of the Company. No Option
shall be exercisable after the expiration of ten (10) years from the date of
grant or prior to approval of the Plan by the stockholders of the Company.

         d.       Payment Upon Exercise. Common Stock purchased upon the
exercise of an Option granted under the Plan shall be paid for as follows:

                  i.       in cash or by check, payable to the order of the
Company;

                  ii. except as the Board may otherwise provide in an Option
Agreement, by delivery of an irrevocable and unconditional undertaking by a
creditworthy broker to deliver promptly to the Company sufficient funds to pay
the exercise price, or by delivery by the Participant to the Company of a copy
of irrevocable and unconditional instructions to a creditworthy broker to
deliver promptly to the Company cash or a check sufficient to pay the exercise
price;

                  iii. to the extent permitted by the Board and explicitly
provided in an Option Agreement (i) by delivery of shares of Common Stock owned
by the Participant valued at their fair market value as determined by the Board
in good faith ("Fair Market Value"), which Common Stock was owned by the
Participant at least six months prior to such delivery, (ii) by delivery of a
promissory note of the Participant to the Company on terms determined by the
Board, or (iii) by payment of such other lawful consideration as the Board may
determine; or

                  iv.      by any combination of the above permitted forms of
payment.

6.       General Provisions Applicable to Options

         a. Transferability of Options. Except as the Board may otherwise
determine or provide in an Option, Options shall not be sold, assigned,
transferred, pledged or otherwise encumbered by the person to whom they are
granted, either voluntarily or by operation of law, except by will or the laws
of descent and distribution, and, during the life of the Participant, shall be
exercisable only by the Participant. References to a Participant, to the extent
relevant in the context, shall include references to authorized transferees.

         b.       Documentation. Each Option under the Plan shall be evidenced
by a written instrument in such form as the Board shall determine. Each Option
may contain terms and conditions in addition to those set forth in the Plan.

<PAGE>

         c. Acquisition Events. The Company shall give the Participant ten (10)
days notice of an Acquisition Event (as defined below), and the Option shall
expire upon the Acquisition Event. An "Acquisition Event" shall mean: (a) any
merger or consolidation which results in the voting securities of the Company
outstanding immediately prior thereto representing immediately thereafter
(either by remaining outstanding or by being converted into voting securities of
the surviving or acquiring entity) less than 50% of the combined voting power of
the voting securities of the Company or such surviving or acquiring entity
outstanding immediately after such merger or consolidation; (b) any sale of all
or substantially all of the assets of the Company; or (c) the complete
liquidation of the Company.

         d. Conditions on Delivery of Stock. The Company will not be obligated
to deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Option have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

7.       Miscellaneous

         a.       No Right To Board Membership or Other Status. Neither the Plan
nor the granting of an Option shall be construed as giving a Participant the
right to continue as a director of the Company.

         b. No Rights As Stockholder. Subject to the provisions of the
applicable Options, no Participant or beneficiary designated by the Participant
shall have any rights as a stockholder with respect to any shares of Common
Stock to be distributed with respect to an Option until becoming the record
holder of such shares.

         c. Effective Date and Term of Plan. The Plan shall become effective on
the date on which it is adopted by the Board. No Options shall be granted under
the Plan after the completion of ten years from the date on which the Plan was
adopted by the Board, but Options previously granted may extend beyond that
date.

         d.       Amendment of Plan. The Board may amend, suspend or terminate
the Plan or any portion thereof at any time.

         e.       Governing Law. The provisions of the Plan and all Options made

         to all shares for which it is vested until the earlier of the Final

Administrator may grant Awards under the Plan in substitution for awards issued
under other plans, or assume under the Plan awards issued under other plans, if

substituted, or the old award is assumed, by reason of a merger, consolidation,
acquisition of property or of stock, reorganization or liquidation (the
"Acquisition Transaction"). In the event that a written agreement pursuant to
which the Acquisition Transaction is completed is approved by the Board and said
agreement sets forth the terms and conditions of the substitution for or
assumption of outstanding awards of the Acquired Entity, said terms and
conditions shall be deemed to be the action of the Plan Administrator without
any further action by the Plan Administrator, except as may be required for
compliance with Rule 16b-3 under the Exchange Act, and the persons holding such
awards shall be deemed to be Participants.

                          SECTION 7. AWARDS OF OPTIONS

7.1   GRANT OF OPTIONS

      The Plan Administrator is authorized under the Plan, in its sole
discretion, to issue Options.

7.2   OPTION EXERCISE PRICE

      The exercise price for shares purchased under an Option shall be as
determined by the Plan Administrator, but shall not be less than 85% of the Fair
Market Value of the Common Stock on the Grant Date.

7.3   TERM OF OPTIONS

      The term of each Option (the "Option Term") shall be as established by the
Plan Administrator or, if not so established, shall be ten years from the Grant
Date.

7.4   EXERCISE OF OPTIONS

      The Plan Administrator shall establish and set forth in each instrument
that evidences an Option the time at which, or the installments in which, the
Option shall vest and become exercisable, which provisions may be waived or
modified by the Plan Administrator at any time. If not so established in the
instrument evidencing the Option, the Option shall vest and become exercisable
according to the following schedule, which may be waived or modified by the Plan
Administrator at any time:

  OR ITS RELATED CORPORATIONS FROM THE               PERCENT OF TOTAL OPTION

continuous service completed thereafter                 An additional 1/48

            After 4 years                                     100%
</TABLE>

      The Plan Administrator may adjust the vesting schedule of an Option held
by a Participant who works less than "full-time" as that term is defined by the
Plan Administrator.

      To the extent that an Option has vested and become exercisable, the Option
may be exercised from time to time by delivery to the Company of a written stock
option exercise agreement or notice, in a form and in accordance with procedures
established by the Plan Administrator, setting forth the number of shares with
respect to which the Option is being exercised, the restrictions imposed on the
shares purchased under such exercise agreement, if any, and such representations
and agreements as may be required by the Plan Administrator, accompanied by
payment in full as described in Section 7.5. An Option may not be exercised as
to less than a reasonable number of shares at any one time, as determined by the
Plan Administrator.

<PAGE>

7.5      PAYMENT OF EXERCISE PRICE

         The exercise price for shares purchased under an Option shall be paid
in full to the Company by delivery of consideration equal to the product of the
Option exercise price and the number of shares purchased. Such consideration
must be paid in cash or by check or, unless the Plan Administrator in its sole
discretion determines otherwise, either at the time the Option is granted or at
any time before it is exercised, in any combination of

      (a) cash or check;

      (b) tendering (either actually or, if and so long as the Common Stock is
registered under Section 12(b) or 12(g) of the Exchange Act, by attestation)
shares of Common Stock already owned by the Participant for at least six months
(or any shorter period necessary to avoid a charge to the Company's earnings for
financial reporting purposes) having a Fair Market Value on the day prior to the
exercise date equal to the aggregate Option exercise price;

      (c) if and so long as the Common Stock is registered under Section 12(b)
or 12(g) of the Exchange Act, delivery of a properly executed exercise notice,
together with irrevocable instructions, to (i) a brokerage firm designated by
the Company to deliver promptly to the Company the aggregate amount of sale or
loan proceeds to pay the Option exercise price and any withholding tax
obligations that may arise in connection with the exercise and (ii) the Company
to deliver the certificates for such purchased shares directly to such brokerage
firm, all in accordance with the regulations of the Federal Reserve Board; or

      (d) such other consideration as the Plan Administrator may permit.

      In addition, to assist a Participant (including a Participant who is an
officer or a director of the Company) in acquiring shares of Common Stock
pursuant to an Award granted under the Plan, the Plan Administrator, in its sole
discretion, may authorize, either at the Grant Date or at any time before the
acquisition of Common Stock pursuant to the Award, (i) the payment by a
Participant of a full-recourse promissory note, (ii) the payment by the
Participant of the purchase price, if any, of the Common Stock in installments,
or (iii) the guarantee by the Company of a loan obtained by the Participant from
a third party. Subject to the foregoing, the Plan Administrator shall in its
sole discretion specify the terms of any loans, installment payments or loan
guarantees, including the interest rate and terms of and security for repayment.

7.6   POST-TERMINATION EXERCISES

      The Plan Administrator shall establish and set forth in each instrument
that evidences an Option whether the Option shall continue to be exercisable,
and the terms and conditions of such exercise, if a Participant ceases to be
employed by, or to provide services to, the Company or its Related Corporations,
which provisions may be waived or modified by the Plan Administrator at any
time. If not so established in the instrument evidencing the Option, the Option
shall be exercisable according to the following terms and conditions, which may
be waived or modified by the Plan Administrator at any time:

      (a) Any portion of an Option that is not vested and exercisable on the
date of termination of the Participant's employment or service relationship (the
"Termination Date") shall expire on such date.

<PAGE>

      (b) Any portion of an Option that is vested and exercisable on the
Termination Date shall expire upon the earliest to occur of

            (i) the last day of the Option Term;

            (ii) if the Participant's Termination Date occurs for reasons other
than Cause, death or Disability, the three-month anniversary of such Termination
Date; and

            (iii) if the Participant's Termination Date occurs by reason of
Disability or death, the one-year anniversary of such Termination Date.

Notwithstanding the foregoing, if the Participant dies after the Termination
Date while the Option is otherwise exercisable, the portion of the Option that
is vested and exercisable on such Termination Date shall expire upon the earlier
to occur of (y) the last day of the Option Term and (z) the first anniversary of
the date of death, unless the Plan Administrator determines otherwise.

      Also notwithstanding the foregoing, in case of termination of the
Participant's employment or service relationship for Cause, the Option shall
automatically expire upon first notification to the Participant of such
termination, unless the Plan Administrator determines otherwise. If a
Participant's employment or service relationship with the Company is suspended
pending an investigation of whether the Participant shall be terminated for
Cause, all the Participant's rights under any Option likewise shall be suspended
during the period of investigation.

      A Participant's transfer of employment or service relationship between or
among the Company and its Related Corporations, or a change in status from an
employee to a consultant, agent, advisor or independent contractor, shall not be
considered a termination of employment or service relationship for purposes of
this Section 7. Employment or service relationship shall be deemed to continue
while the Participant is on a bona fide leave of absence, if such leave was
approved by the Company or a Related Corporation in writing and if continued
crediting of service for purposes of this Section 7 is expressly required by the
terms of such leave or by applicable law (as determined by the Company). The
effect of a Company-approved leave of absence on the terms and conditions of an
Option shall be determined by the Plan Administrator, in its sole discretion.

                             SECTION 8. STOCK AWARDS

8.1   GRANT OF STOCK AWARDS

      The Plan Administrator is authorized to make Awards of Common Stock or
Awards denominated in units of Common Stock on such terms and conditions and
subject to such restrictions, if any (which may be based on continuous service
with the Company or the achievement of performance goals), as the Plan
Administrator shall determine, in its sole discretion, which terms, conditions
and restrictions shall be set forth in the instrument evidencing the Award. The
terms, conditions and restrictions that the Plan Administrator shall have the
power to determine shall include, without limitation, the manner in which shares
subject to Stock Awards are held during the periods they are subject to
restrictions and the circumstances under which forfeiture of the Stock Award
shall occur by reason of termination of the Participant's employment or service
relationship.

<PAGE>

8.2   ISSUANCE OF SHARES

      Upon the satisfaction of any terms, conditions and restrictions prescribed
with respect to a Stock Award, or upon the Participant's release from any terms,
conditions and restrictions of a Stock Award, as determined by the Plan
Administrator, the Company shall release, as soon as practicable, to the
Participant or, in the case of the Participant's death, to the personal
representative of the Participant's estate or as the appropriate court directs,
the appropriate number of shares of Common Stock.

8.3   WAIVER OF RESTRICTIONS

      Notwithstanding any other provisions of the Plan, the Plan Administrator
may, in its sole discretion, waive the forfeiture period and any other terms,
conditions or restrictions on any Stock Award under such circumstances and
subject to such terms and conditions as the Plan Administrator shall deem
appropriate.

                             SECTION 9. WITHHOLDING

      The Company may require the Participant to pay to the Company the amount
of any withholding taxes that the Company is required to withhold with respect
to the grant, vesting or exercise of any Award. Subject to the Plan and
applicable law, the Plan Administrator may, in its sole discretion, permit the
Participant to satisfy withholding obligations (up to the minimum rate), in
whole or in part, by paying cash, by electing to have the Company withhold
shares of Common Stock or by transferring shares of Common Stock to the Company,
in such amounts as are equivalent to the Fair Market Value of the withholding
obligation. The Company shall have the right to withhold from any Award or any
shares of Common Stock issuable pursuant to an Award or from any cash amounts
otherwise due or to become due from the Company to the Participant an amount
equal to such taxes. The Company may also deduct from any Award any other
amounts due from the Participant to the Company or a Related Corporation.

                            SECTION 10. ASSIGNABILITY

      Awards granted under the Plan and any interest therein may not be
assigned, pledged or transferred by the Participant and may not be made subject
to attachment or similar proceedings otherwise than by will or by the applicable
laws of descent and distribution, and, during the Participant's lifetime, such
Awards may be exercised only by the Participant. Notwithstanding the foregoing,
the Plan Administrator, in its sole discretion, may permit such assignment,
transfer and exercisability and may permit a Participant to designate a
beneficiary who may exercise the Award or receive compensation under the Award
after the Participant's death; provided, however, that any Award so assigned or
transferred shall be subject to all the same terms and conditions contained in
the instrument evidencing the Award.

                             SECTION 11. ADJUSTMENTS

11.1  ADJUSTMENT OF SHARES

      In the event that, at any time or from time to time, a stock dividend,
stock split, spin-off, combination or exchange of shares, recapitalization,
merger, consolidation, distribution to shareholders other than a normal cash
dividend, or other change in the Company's corporate or

<PAGE>

capital structure results in (a) the outstanding shares, or any securities
exchanged therefor or received in their place, being exchanged for a different
number or class of securities of the Company or of any other corporation or (b)
new, different or additional securities of the Company or of any other
corporation being received by the holders of shares of Common Stock of the
Company, then the Plan Administrator shall make proportional adjustments in (i)
the maximum number and kind of securities subject to the Plan as set forth in
Section 4.1 and (ii) the number and kind of securities that are subject to any
outstanding Award and the per share price of such securities, without any change
in the aggregate price to be paid therefor. The determination by the Plan
Administrator as to the terms of any of the foregoing adjustments shall be
conclusive and binding. Notwithstanding the foregoing, a dissolution or
liquidation of the Company or a Corporate Transaction shall not be governed by
this Section 11.1 but shall be governed by Sections 11.2 and 11.3, respectively.

11.2  DISSOLUTION OR LIQUIDATION

      In the event of the proposed dissolution or liquidation of the Company,
the Plan Administrator shall notify each Participant as soon as practicable
prior to the effective date of such proposed transaction. The Plan Administrator
in its discretion may permit a Participant to exercise an Option until ten days
prior to such transaction with respect to all vested and exercisable shares of
Common Stock covered thereby and with respect to such number of unvested shares
as the Plan Administrator shall determine. In addition, the Plan Administrator
may provide that any forfeiture provision or Company repurchase option
applicable to any Award shall lapse as to such number of shares as the Plan
Administrator shall determine, contingent upon the occurrence of the proposed
dissolution or liquidation at the time and in the manner contemplated. To the
extent an Option has not been previously exercised, the Option shall terminate
automatically immediately prior to the consummation of the proposed action. To
the extent a forfeiture provision applicable to a Stock Award has not been
waived by the Plan Administrator, the Stock Award shall be forfeited
automatically immediately prior to the consummation of the proposed action.

11.3     CORPORATE TRANSACTION

      In the event of a Corporate Transaction, except as otherwise provided in
the instrument evidencing the Award, each outstanding Option shall be continued,
assumed or an equivalent option or right substituted by the surviving
corporation, the successor corporation or its parent corporation, as applicable
(the "Successor Corporation"). In the event that the Successor Corporation
refuses to continue, assume or substitute for the Option, the Participant shall
fully vest in and have the right to exercise the Option as to all of the shares
of Common Stock subject thereto, including shares as to which the Option would
not otherwise be vested or exercisable. If an Option becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a Corporate
Transaction, the Plan Administrator shall notify the Participant in writing or
electronically that the Option shall be fully vested and exercisable for a
specified time period after the date of such notice, and the Option shall
terminate upon the expiration of such period, in each case conditioned on the
consummation of the Corporate Transaction. For the purposes of this Section
11.3, the Option shall be considered assumed if, following the Corporate
Transaction, the option or right confers the right to purchase or receive, for
each share of Common Stock subject to the Option, immediately prior to the
Corporate Transaction, the consideration (whether stock, cash, or other
securities or property) received in the merger or sale

<PAGE>

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 Corporate
Transaction is not solely common stock of the Successor Corporation, the Plan
Administrator may, with the consent of the Successor Corporation, provide for
the consideration to be received upon the exercise of the Option, for each share
of Common Stock subject thereto, to be solely common stock of the Successor
Corporation equal in fair market value to the per share consideration received
by holders of Common Stock in the Corporate Transaction. All Options shall
terminate and cease to remain outstanding immediately following the consummation
of the Corporate Transaction, except to the extent assumed by the Successor
Corporation.

      In the event of a Corporate Transaction, except as otherwise provided in
the instrument evidencing the Award, the vesting of Shares subject to Stock
Awards shall accelerate, and the forfeiture provisions to which such Shares are
subject shall lapse, if and to the same extent that the vesting of outstanding
Options accelerates in connection with the Corporate Transaction. If unvested
Options are to be assumed, continued or substituted by a Successor Corporation
without acceleration upon the occurrence of a Corporate Transaction, the
forfeiture provisions to which such shares are subject will continue with
respect to shares of the Successor Corporation that may be issued in exchange
for such Shares.

11.4  FURTHER ADJUSTMENT OF AWARDS

      Subject to Sections 11.2 and 11.3, the Plan Administrator shall have the
discretion, exercisable at any time before a sale, merger, consolidation,
reorganization, liquidation or change in control of the Company, as defined by
the Plan Administrator, to take such further action as it determines to be
necessary or advisable, and fair and equitable to the Participants, with respect
to Awards. Such authorized action may include (but shall not be limited to)
establishing, amending or waiving the type, terms, conditions or duration of, or
restrictions on, Awards so as to provide for earlier, later, extended or
additional time for exercise, lifting restrictions and other modifications, and
the Plan Administrator may take such actions with respect to all Participants,
to certain categories of Participants or only to individual Participants. The
Plan Administrator may take such action before or after granting Awards to which
the action relates and before or after any public announcement with respect to
such sale, merger, consolidation, reorganization, liquidation or change in
control that is the reason for such action.

11.5  LIMITATIONS

      The grant of Awards shall in no way affect the Company's right to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

                           SECTION 12. MARKET STANDOFF

      In connection with any underwritten public offering by the Company of its
equity securities pursuant to an effective registration statement filed under
the Securities Act, a person shall not sell, make any short sale of, loan,
hypothecate, pledge, grant any option for the purchase of, or otherwise dispose
of or transfer for value or otherwise agree to engage in any of the

<PAGE>

foregoing transactions with respect to any shares issued pursuant to an Award
granted under the Plan without the prior written consent of the Company or its
underwriters. Such limitations shall be in effect for such period of time as may
be requested by the Company or such underwriters and agreed to by the Company's
officers and directors with respect to their shares; provided, however, that in
no event shall such period exceed 180 days. The limitations of this paragraph
shall in all events terminate two years after the effective date of the
Company's initial public offering. Holders of shares issued pursuant to an Award
granted under the Plan shall be subject to the market standoff provisions of
this paragraph only if the officers and directors of the Company are also
subject to similar arrangements.

      In the event of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
Company's outstanding Common Stock effected as a class without the Company's
receipt of consideration, any new, substituted or additional securities
distributed with respect to the purchased shares shall be immediately subject to
the provisions of this Section 12, to the same extent the purchased shares are
at such time covered by such provisions.

      In order to enforce the limitations of this Section 12, the Company may
impose stop-transfer instructions with respect to the purchased shares until the
end of the applicable standoff period.

                  SECTION 13. AMENDMENT AND TERMINATION OF PLAN

13.1  AMENDMENT OF PLAN

      The Plan may be amended only by the Board in such respects as it shall
deem advisable.

13.2  TERMINATION OF PLAN

      The Board may suspend or terminate the Plan at any time. The Plan shall
have no fixed expiration date.

13.3  CONSENT OF PARTICIPANT

      The amendment or termination of the Plan or the amendment of an
outstanding Award shall not, without the Participant's consent, impair or
diminish any rights or obligations under any Award theretofore granted to the
Participant under the Plan. Notwithstanding the foregoing, any adjustments made
pursuant to Section 11 shall not be subject to these restrictions.

                               SECTION 14. GENERAL

14.1  EVIDENCE OF AWARDS

      Awards granted under the Plan shall be evidenced by a written instrument
that shall contain such terms, conditions, limitations and restrictions as the
Plan Administrator shall deem advisable and that are not inconsistent with the
Plan.

<PAGE>

14.2  NO INDIVIDUAL RIGHTS

      Nothing in the Plan or any Award granted under the Plan shall be deemed to
constitute an employment contract or confer or be deemed to confer on any
Participant any right to continue in the employ of, or to continue any other
relationship with, the Company or any Related Corporation or limit in any way
the right of the Company or any Related Corporation to terminate a Participant's
employment or other relationship at any time, with or without Cause.

14.3  REGISTRATION

      Notwithstanding any other provision of the Plan, the Company shall have no
obligation to issue or deliver any shares of Common Stock under the Plan or make
any other distribution of benefits under the Plan unless such issuance, delivery
or distribution would comply with all applicable laws (including, without
limitation, the requirements of the Securities Act), and the applicable
requirements of any securities exchange or similar entity.

      The Company shall be under no obligation to any Participant to register
for offering or resale or to qualify for exemption under the Securities Act, or
to register or qualify under state securities laws, any shares of Common Stock,
security or interest in a security paid or issued under, or created by, the
Plan, or to continue in effect any such registrations or qualifications if made.
The Company may issue certificates for shares with such legends and subject to
such restrictions on transfer and stop-transfer instructions as counsel for the
Company deems necessary or desirable for compliance by the Company with federal
and state securities laws.

      To the extent that the Plan or any instrument evidencing an Award provides
for issuance of stock certificates to reflect the issuance of shares of Common
Stock, the issuance may be effected on a noncertificated basis, to the extent
not prohibited by applicable law or the applicable rules of any stock exchange.

14.4  NO RIGHTS AS A SHAREHOLDER

      No Option or Stock Award denominated in units shall entitle the
Participant to any cash dividend, voting or other right of a shareholder unless
and until the date of issuance under the Plan of the shares that are the subject
of such Award.

14.5  PARTICIPANTS IN FOREIGN COUNTRIES

      The Plan Administrator shall have the authority to adopt such
modifications, procedures and subplans as may be necessary or desirable to
comply with provisions of the laws of foreign countries in which the Company or
its Related Corporations may operate to assure the viability of the benefits
from Awards granted to Participants employed in such countries and to meet the
objectives of the Plan.

14.6  NO TRUST OR FUND

      The Plan is intended to constitute an "unfunded" plan. Nothing contained
herein shall require the Company to segregate any monies or other property, or
shares of Common Stock, or to create any trusts, or to make any special deposits
for any immediate or deferred amounts

<PAGE>

payable to any Participant, and no Participant shall have any rights that are
greater than those of a general unsecured creditor of the Company.

14.7  SEVERABILITY

      If any provision of the Plan or any Award is determined to be invalid,
illegal or unenforceable in any jurisdiction, or as to any person, or would
disqualify the Plan or any Award under any law deemed applicable by the Plan
Administrator, such provision shall be construed or deemed amended to conform to
applicable laws, or, if it cannot be so construed or deemed amended without, in
the Plan Administrator's determination, materially altering the intent of the
Plan or the Award, such provision shall be stricken as to such jurisdiction,
person or Award, and the remainder of the Plan and any such Award shall remain
in full force and effect.

14.8  CHOICE OF LAW

      The Plan and all determinations made and actions taken pursuant hereto, to
the extent not otherwise governed by the laws of the United States, shall be
governed by the laws of the State of Washington without giving effect to
principles of conflicts of laws.

                           SECTION 15. EFFECTIVE DATE

      The Effective Date is the date on which the Plan is adopted by the Board.
