                           ART TECHNOLOGY GROUP, INC.

                              AMENDED AND RESTATED

                             1996 STOCK OPTION PLAN

1. PURPOSE.

     The purpose of this plan (the "Plan") is to secure for ART TECHNOLOGY
GROUP, INC. (the "Company") and its shareholders the benefits arising from
capital stock ownership by employees, officers and directors of, and consultants
or advisors to, the Company and its parent and subsidiary corporations who are
expected to contribute to the Company's future growth and success. Except where
the context otherwise requires, the term "Company" shall include the parent and
all present and future subsidiaries of the Company as defined in Sections 424(e)
and 424(f) of the Internal Revenue Code of 1986, as amended or replaced from
time to time (the "Code"). Those provisions of the Plan which make express
reference to Section 422 shall apply only to Incentive Stock Options (as is
defined below).

2. TYPE OF OPTIONS AND ADMINISTRATION.

     (a) TYPES OF OPTIONS. Options granted pursuant to the Plan may be either
     incentive stock options ("Incentive Stock Options") meeting the
     requirements of Section 422 of the Code or options which are not intended
     to meet the requirements of Section 422 of the Code ("Non-Statutory
     Options").

     (b) ADMINISTRATION.

          (i) The Plan will be administered by the Board of Directors of the
          Company, whose construction and interpretation of the terms and
          provisions of the Plan shall be final and conclusive. The Board of
          Directors may in its sole discretion grant options to purchase shares
          of the Company's Common Stock ("Common Stock") and issue shares upon
          exercise of such options as provided in the Plan. The Board shall have
          authority, subject to the express provisions of the Plan, to construe
          the respective option agreements and the Plan, to prescribe, amend and
          rescind rules and regulations relating to the Plan, to determine the
          terms and provisions of the respective option agreements, which need
          not be identical, and to make all other determinations which are, in
          the judgment of the Board of Directors, necessary or desirable for the
          administration of the Plan. The Board of Directors may correct any
          defect, supply any omission or reconcile any inconsistency in the Plan
          or in any option agreement 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. No director or person acting
          pursuant to authority delegated by the Board of Directors shall be
          liable for any action or determination under the Plan made in good
          faith.

          (ii) The Board of Directors may, to the full extent permitted by or
          consistent with applicable laws or regulations and Section 2(b)(iii)
          of this Plan, delegate any or all of its powers under the Plan to one
          or more committees (each a "Committee") appointed by

<PAGE>

          the Board of Directors, and if any Committee is so appointed all
          references to the Board of Directors in the Plan shall mean and relate
          to such Committee.

          (iii) While the Common Stock is registered under the Securities
          Exchange Act of 1934, as amended or replaced from time to time (the
          "Exchange Act"), the Board of Directors shall appoint a Committee of
          not less than two members, each member of which shall be an "outside
          director" within the meaning of Section 162(m) of the Code and a
          "non-employee director" as defined in Rule 16b-3 promulgated under the
          Exchange Act. The Committee appointed pursuant to this Section
          2(b)(iii) shall have authority to administer and grant options to such
          employees of, and consultants or advisors to, the Company as specified
          by the Board of Directors, and shall have the sole authority under the
          Plan to administer and grant options to officers, directors and 5%
          shareholders of the Company.

          (iv) The Board of Directors may appoint a second Committee comprised
          of one or more directors, none of whom need be an "outside director"
          within the meaning of Section 162(m) of the Code or a "non-employee
          director" as defined in Rule 16b-3 promulgated under the Exchange Act.
          Any Committee appointed pursuant to this Section 2(b)(iv) shall have
          authority under the Plan to administer and grant options to employees
          of, and consultants or advisors to, the Company as may be designated
          by the Board of Directors, provided that such Committee shall not have
          the authority to administer or grant options to officers, directors
          and 5% shareholders of the Company. Such Committee's authority to
          administer and grant options need not be exclusive, and, if so
          specified by the Board of Directors, other Committees or the Board of
          Directors may administer or grant options to such designated employees
          of, and consultants or advisors to, the Company.

3. ELIGIBILITY. Options may be granted to persons who are, at the time of grant,
employees, officers or directors of, or consultants or advisors to, the Company;
provided, that the class of employees to whom Incentive Stock Options may be
granted shall be limited to all employees of the Company. A person who has been
granted an option may, if he or she is otherwise eligible, be granted additional
options if the Board of Directors shall so determine. Subject to adjustment as
provided in Section 15 below, the maximum number of shares with respect to which
options may be granted to any employee under the Plan shall not exceed 500,000
shares of Common Stock during any calendar year. For the purpose of calculating
such maximum number, (a) an option shall continue to be treated as outstanding
notwithstanding its repricing, cancellation or expiration and (b) the repricing
of an outstanding option or the issuance of a new option in substitution for a
cancelled option shall be deemed to constitute the grant of a new additional
option separate from the original grant of the option that is repriced or
cancelled.

4. STOCK SUBJECT TO PLAN.

     Subject to adjustment as provided in Section 15 below, the maximum number
of shares of Common Stock which may be issued and sold under the Plan is
25,600,000 shares. If an option granted under the Plan shall expire or terminate
for any reason without having been exercised in full, the unpurchased shares
subject to such option shall again be available for

<PAGE>

subsequent option grants under the Plan. If shares issued upon exercise of an
option under the Plan are tendered to the Company in payment of the exercise
price of an option granted under the Plan, such tendered shares shall again be
available for subsequent option grants under the Plan; provided, that in no
event shall such shares be made available for issuance pursuant to exercise of
Incentive Stock Options.

5. FORMS OF OPTION AGREEMENTS.

     Each option shall be evidenced in such form (written, electronic or
otherwise) as the Board of Directors may determine. Each option may contain
terms and conditions in addition to those set forth in the Plan.

6. PURCHASE PRICE.

     (a) GENERAL. Subject to Section 2(b)(iii), the purchase price per share of
     stock deliverable upon the exercise of an option shall be determined by the
     Board of Directors, PROVIDED, however, that in the case of an Incentive
     Stock Option, the exercise price shall not be less than 100% of the fair
     market value of such stock, as determined by the Board of Directors, at the
     time of grant of such option, or less than 110% of such fair market value
     in the case of options described in Section 11(b).

     (b) PAYMENT OF PURCHASE PRICE. Options granted under the Plan may provide
     for the payment of the exercise price by delivery of cash or a check to the
     order of the Company in an amount equal to the exercise price of such
     options, or, to the extent provided in the applicable option agreement,

          (i) by delivery to the Company of shares of Common Stock already owned
          by the optionee having a fair market value equal in amount to the
          exercise price of the options being exercised, provided (x) such
          method of payment is then permitted under applicable law and (y) such
          Common Stock, if acquired directly from the Company, was owned by the
          optionee at least six months prior to such delivery; or

          (ii) by any other means (including, without limitation, by delivery of
          a promissory note of the optionee payable on such terms as are
          specified by the Board of Directors) which the Board of Directors
          determines are consistent with the purpose of the Plan and with
          applicable laws and regulations (including, without limitation, the
          provisions of Regulation T promulgated by the Federal Reserve Board).

The fair market value of any shares of Common Stock or other non-cash
consideration which may be delivered upon exercise of an option shall be
determined by the Board of Directors.

7. OPTION PERIOD.

     Each option and all rights thereunder shall expire on such date as shall be
set forth in the applicable option agreement, except that, in the case of an
Incentive Stock Option, such date shall not be later than ten years after the
date on which the option is granted and, in all cases, options shall be subject
to earlier termination as provided in the Plan.

<PAGE>

8. EXERCISE OF OPTIONS.

     Each option granted under the Plan shall be exercisable either in full or
in installments at such time or times and during such period as shall be set
forth in the agreement evidencing such option, subject to the provisions of the
Plan.

9. NONTRANSFERABILITY OF OPTIONS.

     Except as the Board of Directors may otherwise determine in an option
agreement, 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 optionee, shall be exercisable only by the optionee.
References to an optionee, to the extent relevant in the context, shall include
references to authorized transferees.

10. EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER RELATIONSHIP.

     Subject to the provisions of the Plan, the Board of Directors shall
determine the period of time during which an optionee may exercise an option
following (i) the termination of the optionee's employment or other relationship
with the Company or (ii) the death or disability of the optionee. Such periods
shall be set forth in the agreement evidencing such option.

11. INCENTIVE STOCK OPTIONS.

     Options granted under the Plan which are intended to be Incentive Stock
Options shall be subject to the following additional terms and conditions:

     (a) EXPRESS DESIGNATION. All Incentive Stock Options granted under the Plan
     shall, at the time of grant, be specifically designated as such in the
     option agreement covering such Incentive Stock Options.

     (b) 10% SHAREHOLDER. If any employee to whom an Incentive Stock Option is
     to be granted under the Plan is, at the time of the grant of such option,
     the owner of stock possessing more than 10% of the total combined voting
     power of all classes of stock of the Company (after taking into account the
     attribution of stock ownership rules of Section 424(d) of the Code), then
     the following special provisions shall be applicable to the Incentive Stock
     Option granted to such individual:

          (i) The purchase price per share of the Common Stock subject to such
          Incentive Stock Option shall not be less than 110% of the fair market
          value of one share of Common Stock at the time of grant; and

          (ii) the option exercise period shall not exceed five years from the
          date of grant.

     (c) DOLLAR LIMITATION. For so long as the Code shall so provide, options
     granted to any employee under the Plan (and any other incentive stock
     option plans of the Company) which are intended to constitute Incentive
     Stock Options shall not constitute Incentive Stock Options to the extent
     that such options, in the aggregate, become exercisable for the first

<PAGE>

     time in any one calendar year for shares of Common Stock with an aggregate
     fair market value (determined as of the respective date or dates of grant)
     of more than $100,000.

12. ADDITIONAL PROVISIONS.

     (a) ADDITIONAL OPTION PROVISIONS. The Board of Directors may, in its sole
     discretion, include additional provisions in option agreements covering
     options granted under the Plan, including without limitation restrictions
     on transfer, repurchase rights, commitments to pay cash bonuses, to make,
     arrange for or guaranty loans or to transfer other property to optionees
     upon exercise of options, or such other provisions as shall be determined
     by the Board of Directors; PROVIDED THAT such additional provisions shall
     not be inconsistent with any other term or condition of the Plan and such
     additional provisions shall not cause any Incentive Stock Option granted
     under the Plan to fail to qualify as an Incentive Stock Option within the
     meaning of Section 422 of the Code.

     (b) ACCELERATION, EXTENSION, ETC. The Board of Directors may, in its sole
     discretion, (i) accelerate the date or dates on which all or any particular
     option or options granted under the Plan may be exercised or (ii) extend
     the dates during which all, or any particular, option or options granted
     under the Plan may be exercised.

13. GENERAL RESTRICTIONS.

     (a) INVESTMENT REPRESENTATIONS. The Company may require any person to whom
     an option is granted, as a condition of exercising such option, to give
     written assurances in substance and form satisfactory to the Company to the
     effect that such person is acquiring the Common Stock subject to the option
     for his or her own account for investment and not with any present
     intention of selling or otherwise distributing the same, and to such other
     effects as the Company deems necessary or appropriate in order to comply
     with federal and applicable state securities laws, or with covenants or
     representations made by the Company in connection with any public offering
     of Common Stock.

     (b) COMPLIANCE WITH SECURITIES LAWS. Each option shall be subject to the
     requirement that if, at any time, counsel to the Company shall determine
     that the listing, registration or qualification of the shares subject to
     such option upon any securities exchange or under any state or federal law,
     or the consent or approval of any governmental or regulatory body, or that
     the disclosure of non-public information or the satisfaction of any other
     condition is necessary as a condition of, or in connection with, the
     issuance or purchase of shares thereunder, such option may not be
     exercised, in whole or in part, unless such listing, registration,
     qualification, consent or approval, or satisfaction of such condition shall
     have been effected or obtained on conditions acceptable to the Board of
     Directors. Nothing herein shall be deemed to require the Company to apply
     for or to obtain such listing, registration or qualification, or to satisfy
     such condition.

14. RIGHTS AS A SHAREHOLDER.

     The holder of an option shall have no rights as a shareholder with respect
to any shares covered by the option (including, without limitation, any rights
to receive dividends or non-cash distributions with respect to such shares)
until the date of issue of a stock certificate to him or her

<PAGE>

for such shares. No adjustment shall be made for dividends or other rights for
which the record date is prior to the date such stock certificate is issued.

15. ADJUSTMENT PROVISIONS FOR RECAPITALIZATIONS AND RELATED TRANSACTIONS.

     (a) GENERAL. If, through or as a result of any merger, consolidation, sale
     of all or substantially all of the assets of the Company, reorganization,
     recapitalization, reclassification, stock dividend, stock split, reverse
     stock split or other similar transaction, (i) the outstanding shares of
     Common Stock are increased, decreased or exchanged for a different number
     or kind of shares or other securities of the Company, or (ii) additional
     shares or new or different shares or other securities of the Company or
     other non-cash assets are distributed with respect to such shares of Common
     Stock or other securities, an appropriate and proportionate adjustment may
     be made in (w) the per optionee limit set forth in Section 3, (x) the
     maximum number and kind of shares reserved for issuance under the Plan, (y)
     the number and kind of shares or other securities subject to any then
     outstanding options under the Plan, and (z) the price for each share
     subject to any then outstanding options under the Plan, without changing
     the aggregate purchase price as to which such options remain exercisable.
     Notwithstanding the foregoing, no adjustment shall be made pursuant to this
     Section 15 if such adjustment would cause the Plan to fail to comply with
     Section 422 of the Code.

     (b) BOARD AUTHORITY TO MAKE ADJUSTMENTS. Any adjustments under this Section
     15 will be made by the Board of Directors, whose determination as to what
     adjustments, if any, will be made and the extent thereof will be final,
     binding and conclusive. No fractional shares will be issued under the Plan
     on account of any such adjustments.

16. MERGER, CONSOLIDATION, ASSET SALE, LIQUIDATION, ETC.

     (a) GENERAL. In the event of a consolidation or merger or sale of all or
     substantially all of the assets of the Company in which outstanding shares
     of Common Stock are exchanged for securities, cash or other property of any
     other corporation or business entity or in the event of a liquidation of
     the Company, the Board of Directors of the Company, or the board of
     directors of any corporation assuming the obligations of the Company, may,
     in its discretion, take any one or more of the following actions, as to
     outstanding options: (i) provide that such options shall be assumed, or
     equivalent options shall be substituted, by the acquiring or succeeding
     corporation (or an affiliate thereof), PROVIDED that any such options
     substituted for Incentive Stock Options shall meet the requirements of
     Section 424(a) of the Code, (ii) upon written notice to the optionees,
     provide that all unexercised options will terminate immediately prior to
     the consummation of such transaction unless exercised by the optionee
     within a specified period following the date of such notice, (iii) in the
     event of a merger under the terms of which holders of the Common Stock will
     receive upon consummation thereof a cash payment for each share surrendered
     in the merger (the "Merger Price"), make or provide for a cash payment to
     the optionees equal to the amount (if any) by which (A) the Merger Price
     times the number of shares of Common Stock subject to such outstanding
     options (whether or not then exercisable) exceeds (B) the aggregate
     exercise price of all such outstanding options in exchange for the
     termination of such options, and (iv) provide that all or any outstanding
     options shall become exercisable in full immediately prior to such event.

<PAGE>

     (b) SUBSTITUTE OPTIONS. The Company may grant options under the Plan in
     substitution for options held by employees of another corporation who
     become employees of the Company, or a subsidiary of the Company, as the
     result of a merger or consolidation of the employing corporation with the
     Company or a subsidiary of the Company, or as a result of the acquisition
     by the Company, or one of its subsidiaries, of property or stock of the
     employing corporation. The Company may direct that substitute options be
     granted on such terms and conditions as the Board of Directors considers
     appropriate in the circumstances.

17. NO SPECIAL EMPLOYMENT RIGHTS.

     Nothing contained in the Plan or in any option shall confer upon any
optionee any right with respect to the continuation of his or her employment by
the Company or interfere in any way with the right of the Company at any time to
terminate such employment or to increase or decrease the compensation of the
optionee.

18. OTHER EMPLOYEE BENEFITS.

     Except as to plans which by their terms include such amounts as
compensation, the amount of any compensation deemed to be received by an
employee as a result of the exercise of an option or the sale of shares received
upon such exercise will not constitute compensation with respect to which any
other employee benefits of such employee are determined, including, without
limitation, benefits under any bonus, pension, profit-sharing, life insurance or
salary continuation plan, except as otherwise specifically determined by the
Board of Directors.

19. AMENDMENT OF THE PLAN.

     (a) The Board of Directors may at any time, and from time to time, modify
     or amend the Plan in any respect, except that if at any time the approval
     of the shareholders of the Company is required under Section 422 of the
     Code or any successor provision with respect to Incentive Stock Options,
     the Board of Directors may not effect such modification or amendment
     without such approval.

     (b) The termination or any modification or amendment of the Plan shall not,
     without the consent of an optionee, affect his or her rights under an
     option previously granted to him or her. With the consent of the optionee
     affected, the Board of Directors may amend outstanding option agreements in
     a manner not inconsistent with the Plan. The Board of Directors shall have
     the right to amend or modify the terms and provisions of the Plan and of
     any outstanding Incentive Stock Options granted under the Plan to the
     extent necessary to qualify any or all such options for such favorable
     federal income tax treatment (including deferral of taxation upon exercise)
     as may be afforded incentive stock options under Section 422 of the Code.

<PAGE>

20. WITHHOLDING.

     Each optionee shall pay to the Company, or make provision satisfactory to
the Board of Directors for payment of, any taxes required by law to be withheld
in connection with options to such optionee no later than the date of the event
creating the tax liability. Except as the Board of Directors may otherwise
provide in an option, when the Common Stock is registered under the Exchange
Act, optionee may satisfy such tax obligations in whole or in part by delivery
of shares of Common Stock, including shares retained from the option creating
the tax obligation, valued at their fair market value; provided, however, that
the total tax withholding where stock is being used to satisfy such tax
obligations cannot exceed the Company's minimum statutory withholding
obligations (based on minimum statutory withholding rates for federal and state
tax purposes, including payroll taxes, that are applicable to such supplemental
taxable income). The Company may, to the extent permitted by law, deduct any
such tax obligations from any payment of any kind otherwise due to a optionee.

21. CANCELLATION AND NEW GRANT OF OPTIONS, ETC.

     The Board of Directors shall have the authority to effect, at any time and
from time to time, with the consent of the affected optionees, (i) the
cancellation of any or all outstanding options under the Plan and the grant in
substitution therefor of new options under the Plan covering the same or
different numbers of shares of Common Stock and having an option exercise price
per share which may be lower or higher than the exercise price per share of the
cancelled options or (ii) the amendment of the terms of any and all outstanding
options under the Plan to provide an option exercise price per share which is
higher or lower than the then-current exercise price per share of such
outstanding options.

22. EFFECTIVE DATE AND DURATION OF THE PLAN.

     (a) EFFECTIVE DATE. The Plan shall become effective when adopted by the
     Board of Directors, but no option granted under the Plan shall become
     exercisable unless and until the Plan shall have been approved by the
     Company's shareholders. If such shareholder approval is not obtained within
     twelve months after the date of the Board's adoption of the Plan, options
     previously granted under the Plan shall not vest and shall terminate and no
     options shall be granted thereafter. Amendments to the Plan not requiring
     shareholder approval shall become effective when adopted by the Board of
     Directors; amendments requiring shareholder approval (as provided in
     Section 19) shall become effective when adopted by the Board of Directors,
     but no option granted after the date of such amendment shall become
     exercisable (to the extent that such amendment to the Plan was required to
     enable the Company to grant such option to a particular person) unless and
     until such amendment shall have been approved by the Company's
     shareholders. If such shareholder approval is not obtained within twelve
     months of the Board's adoption of such amendment, any options granted on or
     after the date of such amendment shall terminate to the extent that such
     amendment was required to enable the Company to grant such option to a
     particular optionee. Subject to this limitation, options may be granted
     under the Plan at any time after the effective date and before the date
     fixed for termination of the Plan.

<PAGE>

     (b) TERMINATION. Unless sooner terminated in accordance with Section 16,
     the Plan shall terminate upon the close of business on the day next
     preceding the tenth anniversary of the date of its adoption by the Board of
     Directors. Options outstanding on such date shall continue to have force
     and effect in accordance with the provisions of the instruments evidencing
     such options.

23. PROVISION FOR FOREIGN PARTICIPANTS.

     The Board of Directors may, without amending the Plan, modify awards or
options granted to participants who are foreign nationals or employed outside
the United States to recognize differences in laws, rules, regulations or
customs of such foreign jurisdictions with respect to tax, securities, currency,
employee benefit or other matters.Prepared by MERRILL CORPORATION
