                                  ARTICLE II
                               Award of Options
                               ----------------

     2.1  Eligibility for awards.  Awards of Options may be made to any Employee
selected by the Committee.  In making this selection, and in determining the
form and amount of Options, the Committee will consider any factors it deems
relevant.

     2.2  Awarding of Options.  Recipients of Options are determined from time
to time by the Committee.  The Committee may condition the award of any Option
on the surrender by the Participant of right to receive salary, bonus or other
cash compensation otherwise payable in the future by the Employer to the
Participant.  The Committee may also award other options at its discretion.
Awards become effective on the Grant Date.  Awards may be made at any time on or
after the Effective Date and prior to the termination of the Plan.

     2.3  Selection of Designated Property; Exercise Price; Other Terms.  When
an Option is awarded, the Committee will specify the Designated Property that
may be purchased by exercise of the Option, the Grant Date, and will fix any
terms of the Option not specified in the Plan.  On the day the Option is
awarded, the Designated Property that may be purchased by exercising the Option
must be readily tradable on an established market or consist wholly of interests
readily tradable on an established market.  Unless otherwise specified in a
particular Option Agreement, the Exercise Price will equal the greater of
twenty-five percent (25%) of the Fair Market Value of the Designated Property on
the Grant Date or on the Exercise Date.

     2.4  Acquisition of Designated Property. If the Company acquires Designated
Property purchasable upon the exercise of an Option, such Designated Property
must:

     (a) not be subject to any security interest, whether perfected or not, or
     to any option or contract under which any other person may acquire any
     interest in it; and

     (b) be readily tradable on an established market or consist wholly of
     interests in  property that is readily tradable  on an established market.

     2.5  Effect of dividends and distributions with respect to Designated
Property under Option.   All dividends and distributions with respect to
Designated Property will be treated as if reinvested in additional property of
the same kind (or as nearly the same kind as feasible, if the property of the
same kind is not available), and will immediately be subject to the Option
related to the Designated Property.  However, the Exercise Price of an Option to
purchase Designated Property will be adjusted to include the greater of twenty-
five percent (25%) of the fair market value of the reinvestment on the date of
the reinvestment or the date of exercise of the Option.  The reinvestment of
dividends and distributions does not extend or modify the term or other
conditions of the Option, other than adjusting the Exercise Price and amount of
Designated Property.

  2.6  Substitution of other property for Designated Property. At any time after
the grant of an Option, the Committee may, in its discretion, substitute other
property of equal value for Designated Property subject to that Option.  After
substitution, such Option shall not be exercisable for six months or the period
specified in the Option Agreement, whichever is less.

                                  ARTICLE III
                              Exercise of Options
                              -------------------

3.1  Period for exercise of Options.  Except as otherwise provided in the Plan,
Options may be exercised by a Participant at any time during the period
beginning six months after the Grant Date and ending on the earliest of:

        (a)    nine (9) months after the Grant Date, or if later, sixty (60)
               days following the end of the calendar year in which Termination
               of Employment occurs as a result of the Participant's Voluntary
               Termination of Employment or Termination for Cause,

        (b)    one (1) year after the Participant's Termination of Employment as
               a result of the Participant's death,

        (c)    three (3) years after Severance of Employment pursuant to Company
               programs not designated under (d) below,

        (d)    ten (10) years after the Participant's Termination of Employment,
               if such Participant terminates due to retirement, disability,
               designated Severance of Employment, or other situations
               designated by the Company, or

        (e)    twenty (20) years after the Grant Date.

If the Company has a Change of Control, as defined in the Amended and Restated
BANC ONE CORPORATION Compensation Deferral Plan, all Awards of Options hereunder
may be exercised by the Participant as of the first business day following the
change of control.

If the Participant is or may be an employee whose remuneration from the Company
is subject to Code Section 162(m), as determined by the Committee, the Committee
may condition, limit and/or delay the exercise of such Participant's Options in
such manner as the Committee may in good faith determine to be necessary, or
desirable, in order to prevent disallowance of the Company's deductions by
reason of Code Section 162(m) with respect to the exercise of such Options.

                                     Page 5
<PAGE>

An Option may not be exercised during the a Participant's lifetime except by the
Participant or, in the event of the Participant's legal incapacity, by his
guardian or legal representative acting in a fiduciary capacity on behalf of the
Participant under state law and court supervision.  If a Participant dies before
all of the Options have been exercised, any Options that remain outstanding may
be exercised by the Beneficiary, subject to all of the terms, conditions, and
restrictions applicable to the Options had death not occurred.

Any Option that has not been exercised by the close of business on the last day
provided for under the Plan or in the Option Agreement for exercise thereof (or
under any extension thereof) will expire automatically and will not thereafter
be exercisable.

     3.2  Procedure for exercising an Option.  A Participant may exercise an
Option by giving written notice to the Committee.  Such written notice of
exercise must be in such a form as the Committee may require, must be properly
completed, and must be mailed or delivered to the Committee, or to such other
person(s) designated pursuant to Section 5.1.  Options may be exercised, in any
combinations or amounts subject to the restrictions set for in the Plan, except
that the Committee may from time to time require a minimum number of Options to
be exercised at one time, but such minimum number will not be designed to impose
any substantial restriction on a Participant's ability to exercise Options.
Except as otherwise provided in the Plan or in any Option Agreement, the
"Exercise Date" of an Option will be the first Business Day on which the
Committee is in actual receipt of the written notice of exercise.  Upon exercise
of an Option, the Participant must pay the Exercise Price of the Option to the
Company.  The consideration to be paid in satisfaction of the Exercise Price
will be cash in the form of currency, check, or other cash equivalent, in each
case acceptable to the Company. The Exercise Price must be paid in full before
the delivery of the Designated Property will be made in accordance with Section
3.4.

     3.3  Tax Withholding.  Whenever Designated Property is to be delivered upon
exercise of an Option under the Plan, the Company will require as a condition of
such delivery (a) a cash payment by the Participant of an amount sufficient to
satisfy all federal, state, local, foreign or other tax withholding requirements
related thereto, (b) the withholding of such amount from any Designated Property
to be delivered to the Participant, (c) the withholding of such amount from
compensation otherwise due to the Participant, or (d) any combination of the
foregoing, at the election of the Participant with the consent of the Company.
As soon as practicable following receipt by the Company of a properly completed
notice of exercise of an Option from a Participant, the Company will notify the
Participant of the withholding amount determined by the Company.

     3.4  Delivery of Designated Property.  Following the Exercise Date and
receipt by the Company of both the Exercise Price and tax withholding or
authorization to withhold, the Company will use its reasonable best efforts to
deliver the Designated Property to the Participant, or cause such delivery of
the Designated Property to the Participant to occur within ten business days.
The Company will not, however, be required to issue any fractional shares of
Designated Property, and the Committee may provide for the elimination of
fractions or for the settlement thereof in cash.  In the event that the listing,
registration or qualification of the Option or the

                                     Page 6
<PAGE>

Designated Property on any securities exchange or under any state or federal
law, or the consent or approval of any governmental regulatory body, is
necessary as a condition of, or in connection with, the exercise of the Option,
then the Option will not be exercised in whole or in part until such listing,
registration, qualification, consent or approval has been effected or obtained.

     3.5  Vesting of Options.  Participants shall at all times be 100% vested in
Options granted by the Committee under this Plan unless otherwise provided in
the Option Agreement.

     3.6  Inalienability of Options.  No Option granted under this Plan may be
transferred, assigned or alienated, except as provided herein, and no Option
shall be subject to execution, attachment or similar process, and any attempt to
transfer, assign, alienate, execute upon attach, or subject to process any
Option will be void.

     3.7  Beneficiary.  The Committee may permit a Participant to designate a
Beneficiary on a form therefor prescribed by the Committee on which the
Participant may designate a Beneficiary (and change a previous designation) by
filing the prescribed form with the Committee.  If so prescribed by the
Committee, such form may allow the designation of multiple Beneficiaries and/or
successor Beneficiary or successor Beneficiaries.  The consent of the
Participant's current Beneficiary is not required for a change of Beneficiary,
and no Beneficiary has any rights under this Plan except as are provided by its
terms.  The rights of a Beneficiary who predeceases the Participant immediately
terminate.  Unless a Beneficiary has been designated in accordance with this
Section 3.7 and such Beneficiary survives the Participant, the Beneficiary of
any Participant is the estate.

                                  ARTICLE IV
                     Amendment or Termination of the Plan

                    after the Grant Date and by its terms applies to the Option,

                    2.6,

             (d)    any circumstances not specified in Paragraphs (a), (b), (c),
                    with the consent of the Participant.

Any such amendment by the Committee is binding upon the affected Participant,
any Beneficiary of the Participant, and all other parties in interest.  The
