          This GUARANTEE AGREEMENT (the "Preferred Securities Guarantee"), dated
as of August 30, 2000, is executed and delivered by BANK ONE CORPORATION, a
Delaware corporation (the "Guarantor"), and The Chase Manhattan Bank, as trustee
(the "Preferred Guarantee Trustee"), for the benefit of the Holders (as defined
herein) from time to time of the Preferred Securities (as defined herein) of
BANK ONE Capital III, a Delaware statutory business trust (the "Issuer").

          WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the

named therein, the Guarantor, as sponsor, and the holders from time to time of
undivided beneficial interests in the assets of the Issuer, the Issuer is
issuing on the date hereof 475,000 preferred securities, having an aggregate
liquidation amount of $475,000,000, designated the 8.750% Preferred Securities
(the "Preferred Securities");

          WHEREAS, as incentive for the Holders to purchase the Preferred
Securities, the Guarantor desires irrevocably and unconditionally to agree, to
the extent set forth in this Preferred Securities Guarantee, to pay to the
Holders of the Preferred Securities the Guarantee Payments (as defined herein)
and to make certain other payments on the terms and conditions set forth herein.

          WHEREAS, the Guarantor is also executing and delivering a guarantee
agreement (the "Common Securities Guarantee") in substantially identical terms
to this Preferred Securities Guarantee for the benefit of the holders of the
Common Securities (as defined herein), except that if an Event of Default (as
defined in the Indenture), has occurred and is continuing, the rights of holders
of the Common Securities to receive Guarantee Payments under the Common
Securities Guarantee are subordinated to the rights of Holders of Preferred
Securities to receive Guarantee Payments under this Preferred Securities
Guarantee.

          NOW, THEREFORE, in consideration of the purchase by each Holder of
Preferred Securities, which purchase the Guarantor hereby agrees shall benefit
the Guarantor, the Guarantor executes and delivers this Preferred Securities
Guarantee for the benefit of the Holders.

     that, the Preferred Guarantee Trustee shall be protected in withholding

SECTION 3.1  Powers and Duties of the Preferred Guarantee Trustee
             ----------------------------------------------------

               (1)  This Preferred Securities Guarantee shall be held by the
     Preferred Guarantee Trustee for the benefit of the Holders, and the
     Preferred Guarantee Trustee shall not transfer this Preferred Securities
     Guarantee to any Person except a Holder exercising his or her rights
     pursuant to Section 5.4(c) or to a Successor Preferred Guarantee Trustee on
     acceptance by such Successor Preferred Guarantee Trustee of its appointment
     to act as Successor Preferred Guarantee Trustee. The right, title and
     interest of the Preferred Guarantee Trustee shall automatically vest in any
     Successor Preferred Guarantee Trustee, and such vesting and cessation of
     title shall be effective whether or not conveyancing documents have been
     executed and delivered pursuant to the appointment of such Successor
     Preferred Guarantee Trustee.

               (2)  If an Event of Default actually known to a Responsible
     Officer of the Preferred Guarantee Trustee has occurred and is continuing,

     Guarantee for the benefit of the Holders.

               (3)  The Preferred Guarantee Trustee, before the occurrence of
     any Event of Default and after the curing of all Events of Default that may
     have occurred, shall undertake to perform only such duties as are
     specifically set forth in this Preferred Securities Guarantee, and no
     implied covenants shall be read into this Preferred Securities Guarantee
     against the Preferred Guarantee Trustee. In case an Event of Default has
     occurred (that has not been cured or waived pursuant to Section 2.6) and is
     actually known to a Responsible Officer of the Preferred Guarantee Trustee,
     the Preferred Guarantee Trustee shall exercise such of the rights and
     powers vested in it by this Preferred Securities Guarantee, and use the
     same degree of care and skill in its exercise thereof, as a prudent person
     would exercise or use under the circumstances in the conduct of his or her
     own affairs.

                                       8


             (4)  No provision of this Preferred Securities Guarantee shall be
     construed to relieve the Preferred Guarantee Trustee from liability for its
     own negligent action, its own negligent failure to act, or its own willful
     misconduct, except that:

                  (1)   prior to the occurrence of any Event of Default and
             after the curing or waiving of all such Events of Default that may
             have occurred:

                                   (1)  the duties and obligations of the
                  Preferred Guarantee Trustee shall be determined solely by the
                  express provisions of this Preferred Securities Guarantee, and
                  the Preferred Guarantee Trustee shall not be liable except for
                  the performance of such duties and obligations as are
                  specifically set forth in this Preferred Securities Guarantee,
                  and no implied covenants or obligations shall be read into
                  this Preferred Securities Guarantee against the Preferred
                  Guarantee Trustee; and

                        (2)  in the absence of bad faith on the part of the
                  Preferred Guarantee Trustee, the Preferred Guarantee Trustee
                  may conclusively rely, as to the truth of the statements and
                  the correctness of the opinions expressed therein, upon any
                  certificates or opinions furnished to the Preferred Guarantee
                  Trustee and conforming to the requirements of this Preferred
                  Securities Guarantee; but in the case of any such certificates
                  or opinions that by any provision hereof are specifically
                  required to be furnished to the Preferred Guarantee Trustee,
                  the Preferred Guarantee Trustee shall be under a duty to
                  examine the same to determine whether or not they conform to
                  the requirements of this Preferred Securities Guarantee;

                  (2)   the Preferred Guarantee Trustee shall not be liable for
             any error of judgment made in good faith by a Responsible Officer
             of the Preferred Guarantee Trustee, unless it shall be proved that
             the Preferred Guarantee Trustee was negligent in ascertaining the
             pertinent facts upon which such judgment was made;

                  (3)   the Preferred Guarantee Trustee shall not be liable with
             respect to any action taken or omitted to be taken by it in good
             faith in accordance with the direction of the Holders of not less
             than a Majority in liquidation amount of the Preferred Securities
             relating to the time, method and place of conducting any proceeding
             for any remedy available to the Preferred Guarantee Trustee, or
             exercising any trust or power conferred upon the Preferred
             Guarantee Trustee under this Preferred Securities Guarantee; and

                  (4)   no provision of this Preferred Securities Guarantee
             shall require the Preferred Guarantee Trustee to expend or risk its
             own funds or otherwise incur personal financial liability in the
             performance of any of its duties or in the exercise of any of its
             rights or powers, if the Preferred Guarantee Trustee shall have
             reasonable grounds for believing that the repayment of such funds
             or liability is not reasonably assured to it under the terms of
             this Preferred Securities Guarantee or indemnity, reasonably
             satisfactory to the Preferred Guarantee Trustee, against such risk
             or liability is not reasonably assured to it.

             upon, any resolution, certificate, statement, instrument, opinion,
             report, notice, request, direction, consent, order, bond,

                                       9


                    (2)  Any direction or act of the Guarantor contemplated by
             this Preferred Securities Guarantee shall be sufficiently evidenced
             by an Officers' Certificate.

                    (3)  Whenever, in the administration of this Preferred
             Securities Guarantee, the Preferred Guarantee Trustee shall deem it
             desirable that a matter be proved or established before taking,
             suffering or omitting any action hereunder, the Preferred Guarantee
             Trustee (unless other evidence is herein specifically prescribed)
             may, in the absence of bad faith on its part, request and
             conclusively rely upon an Officers' Certificate which, upon receipt
             of such request, shall be promptly delivered by the Guarantor.

                    (4)  The Preferred Guarantee Trustee shall have no duty to
             see to any recording, filing or registration of any instrument (or

                    (5)  The Preferred Guarantee Trustee may consult with
             counsel of its selection, and the advice or opinion of such counsel
             with respect to legal matters shall be full and complete
             authorization and protection in respect of any action taken,
             suffered or omitted by it hereunder in good faith and in accordance
             with such advice or opinion. Such counsel may be counsel to the
             Guarantor or any of its Affiliates and may include any of its
             employees. The Preferred Guarantee Trustee shall have the right at
             any time to seek instructions concerning the administration of this
             Preferred Securities Guarantee from any court of competent
             jurisdiction.

                    (6)  The Preferred Guarantee Trustee shall be under no
             obligation to exercise any of the rights or powers vested in it by
             this Preferred Securities Guarantee at the request or direction of
             any Holder, unless such Holder shall have provided to the Preferred
             Guarantee Trustee such security and indemnity, reasonably
             satisfactory to the Preferred Guarantee Trustee, against the costs,
             expenses (including attorneys' fees and expenses and the expenses
             of the Preferred Guarantee Trustee's agents, nominees or
             custodians) and liabilities that might be incurred by it in
             complying with such request or direction, including such reasonable
             advances as may be requested by the Preferred Guarantee Trustee;
             provided that, nothing contained in this Section 3.2(a)(vi) shall
             be taken to relieve the Preferred Guarantee Trustee, upon the
             occurrence of an Event of Default, of its obligation to exercise
             the rights and powers vested in it by this Preferred Securities
             Guarantee.

                    (7)  The Preferred Guarantee Trustee shall not be bound to
             make any investigation into the facts or matters stated in any
             resolution, certificate, statement, instrument, opinion, report,
             notice, request, direction, consent, order, bond, debenture, note,
             other evidence of indebtedness or other paper or document, but the
             Preferred Guarantee Trustee, in its discretion, may make such
             further inquiry or investigation into such facts or matters as it
             may see fit.

                    (8)  The Preferred Guarantee Trustee may execute any of the
             trusts or powers hereunder or perform any duties hereunder either
             directly or by or through agents, nominees, custodians or
             attorneys, and the Preferred Guarantee Trustee shall not be
             responsible for any misconduct or negligence on the part of any
             agent or attorney appointed with due care by it hereunder.

                    (9)  Any action taken by the Preferred Guarantee Trustee or
             its agents hereunder shall bind the Holders, and the signature of
             the Preferred Guarantee Trustee or its agents alone shall be
             sufficient and effective to perform any such action. No third party
             shall be required to inquire as to the authority of the Preferred
             Guarantee Trustee to so act or as to its compliance with any of the
             terms and provisions of this Preferred Securities Guarantee, both
             of which shall be conclusively evidenced by the Preferred Guarantee
             Trustee's or its agent's taking such action.

                                       10


                   (10)  Whenever in the administration of this Preferred
             Securities Guarantee the Preferred Guarantee Trustee shall deem it
             desirable to receive instructions with respect to enforcing any
             remedy or right or taking any other action hereunder, the Preferred
             Guarantee Trustee (i) may request instructions from the Holders of
             a Majority in liquidation amount of the Preferred Securities, (ii)
             may refrain from enforcing such remedy or right or taking such
             other action until such instructions are received, and (iii) shall
             be protected in conclusively relying on or acting in accordance
             with such instructions.

                   (11)  The Preferred Guarantee Trustee shall not be liable for
             any action taken, suffered or omitted to be taken by it in good
             faith and reasonably believed by it to be authorized or within the
             discretion or rights or powers conferred upon it by this Preferred
             Securities Guarantee.

             (2)   No provision of this Preferred Securities Guarantee shall be
     deemed to impose any duty or obligation on the Preferred Guarantee Trustee
     to perform any act or acts or exercise any right, power, duty or obligation
     conferred or imposed on it in any jurisdiction in which it shall be
     illegal, or in which the Preferred Guarantee Trustee shall be unqualified
     or incompetent in accordance with applicable law, to perform any such act
     or acts or to exercise any such right, power, duty or obligation.  No
     permissive power or authority available to the Preferred Guarantee Trustee
     shall be construed to be a duty.

SECTION 4.1  Preferred Guarantee Trustee; Eligibility
             ----------------------------------------

             (1)   There shall at all times be a Preferred Guarantee Trustee
which shall:

                   (1)   not be an Affiliate of the Guarantor; and

                   (2)   be a corporation organized and doing business under the

             thereof or of the District of Columbia, or a corporation or Person
             permitted by the Securities and Exchange Commission to act as an
             institutional trustee under the Trust Indenture Act, authorized
             under such laws to exercise corporate trust powers, having a
             combined capital and surplus of at least fifty million U.S. dollars
             ($50,000,000), and subject to supervision or examination by
             Federal, State, Territorial or District of Columbia authority. If
             such corporation publishes reports of condition at least annually,
             pursuant to law or to the requirements of the supervising or
             examining authority referred to above, then, for the purposes of
             this Section 4.1(a)(ii), the combined capital and surplus of such
             corporation shall be deemed to be its combined capital and surplus
             as set forth in its most recent report of condition so published.

             (2)   If at any time the Preferred Guarantee Trustee shall cease to

     shall immediately resign in the manner and with the effect set out in
     Section 4.2(c).

                                       11


             (3)   If the Preferred Guarantee Trustee has or shall acquire any
     "conflicting interest" within the meaning of Section 310(b) of the Trust
     Indenture Act, the Preferred Guarantee Trustee and Guarantor shall in all
     respects comply with the provisions of Section 310(b) of the Trust
     Indenture Act, subject to the penultimate paragraph thereof. To the extent
     permitted by the Trust Indenture Act, the Preferred Guarantee Trustee shall

     Securities Guarantee by virtue of being trustee under the Indentures
     originally dated as of November 15, 1996 and January 1, 1997, between the
     Company and the Preferred Guarantee Trustee or by virtue of being (i) a
     trustee on the Series A Declaration, the Series B Declaration, the 1997

             (1)   Subject to Section 4.2(b), the Preferred Guarantee Trustee
     may be appointed or removed without cause at any time by the Guarantor
     except during an Event of Default.

             (2)   The Preferred Guarantee Trustee shall not be removed in
     accordance with Section 4.2(a) until a Successor Preferred Guarantee
     Trustee has been appointed and has accepted such appointment by written
     instrument executed by such Successor Preferred Guarantee Trustee and
     delivered to the Guarantor.

             (3)   The Preferred Guarantee Trustee appointed to office shall
     hold office until a Successor Preferred Guarantee Trustee shall have been
     appointed or until its removal or resignation. The Preferred Guarantee
     Trustee may resign from office (without need for prior or subsequent
     accounting) by an instrument in writing executed by the Preferred Guarantee
     Trustee and delivered to the Guarantor, which resignation shall not take
     effect until a Successor Preferred Guarantee Trustee has been appointed and
     has accepted such appointment by instrument in writing executed by such
     Successor Preferred Guarantee Trustee and delivered to the Guarantor and
     the resigning Preferred Guarantee Trustee.

             (4)   If no Successor Preferred Guarantee Trustee shall have been
     appointed and accepted appointment as provided in this Section 4.2 within
     60 days after delivery of an instrument of removal or resignation, the
     Preferred Guarantee Trustee resigning or being removed may petition any
     court of competent jurisdiction for appointment of a Successor Preferred
     Guarantee Trustee. Such court may thereupon, after prescribing such notice,
     if any, as it may deem proper, appoint a Successor Preferred Guarantee
     Trustee.

             (5)   No Preferred Guarantee Trustee shall be liable for the acts
     or omissions to act of any Successor Preferred Guarantee Trustee.

             (6)   Upon termination of this Preferred Securities Guarantee or
     removal or resignation of the Preferred Guarantee Trustee pursuant to this
     Section 4.2, the Guarantor shall pay to the Preferred Guarantee Trustee all
     amounts due to the Preferred Guarantee Trustee accrued to the date of such

under this Preferred Securities Guarantee shall in no way be affected or
impaired by reason of the happening from time to time of any of the following:

             (1)   the release or waiver, by operation of law or otherwise, of
     the performance or observance by the Issuer of any express or implied
     agreement, covenant, term or condition relating to the Preferred Securities
     to be performed or observed by the Issuer;

             (2)   the extension of time for the payment by the Issuer of all or

     Distribution or any other sums payable under the terms of the Preferred
     Securities or the extension of time for the performance of any other
     obligation under, arising out of, or in connection with, the Preferred
     Securities (other than an extension of time for payment of Distributions,

     results from the extension of any interest payment period on the Debentures
     or any extension of the maturity date of the Debentures permitted by the
     Indenture);

             (3)   any failure, omission, delay or lack of diligence on the part
     of the Holders to enforce, assert or exercise any right, privilege, power
     or remedy conferred on the Holders pursuant to the terms of the Preferred
     Securities, or any action on the part of the Issuer granting indulgence or
     extension of any kind;

             (4)   the voluntary or involuntary liquidation, dissolution, sale
     of any collateral, receivership, insolvency, bankruptcy, assignment for the

             (6)   the settlement or compromise of any obligation guaranteed
     hereby or hereby incurred; or

             (7)   any other circumstance whatsoever that might otherwise
     constitute a legal or equitable discharge or defense of a guarantor, it
     being the intent of this Section 5.3 that the obligations of the Guarantor
     hereunder shall be absolute and unconditional under any and all
     circumstances.

             There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4  Rights of Holders
             -----------------

             (1)   The Issuer expressly acknowledges that (i) this Preferred
     Securities Guarantee will be deposited with the Preferred Guarantee Trustee
     to be held for the benefit of the Holders and (ii) the Preferred Guarantee
     Trustee has the right to enforce this Preferred Securities Guarantee on
     behalf of the Holders.

             (2)   The Holders of a Majority in liquidation amount of the
     Preferred Securities have the right to direct the time, method and place of
     conducting of any proceeding for any remedy available to the Preferred
     Guarantee Trustee in respect of this Preferred Securities Guarantee or
     exercising any trust or power conferred upon the Preferred Guarantee
     Trustee under this Preferred Securities Guarantee; provided, however, that,
     subject to Section 3.1, the Preferred Guarantee Trustee shall have the
     right to decline to follow any such direction if the Preferred Guarantee
     Trustee shall determine that the action so directed would be unjustly
     prejudicial to the Holders not taking part in such direction or if the
     Preferred Guarantee Trustee being advised by counsel determines that the
     action or proceeding so directed may not lawfully be taken or if the
     Preferred Guarantee Trustee in good faith by its board of directors or
     trustees, executive committee, or a trust committee of directors or
     trustees and/or Responsible Officers shall determine that the action or
     proceeding so directed would involve the Preferred Guarantee Trustee in
     personal liability.

             (3)   If the Preferred Guarantee Trustee fails to enforce such
     Preferred Securities Guarantee, any Holder may institute a legal proceeding
     directly against the Guarantor to enforce the Preferred Guarantee Trustee's
     rights under this Preferred Securities Guarantee, without first instituting
     a legal proceeding against the Issuer, the Preferred Guarantee Trustee or
     any other person or entity. The Guarantor waives any right or remedy to
     require that any action be brought first against the Issuer or any other
     person or entity before proceeding directly against the Guarantor.

SECTION 5.5  Guarantee of Payment
             --------------------

and not of collection.

             The Guarantor shall be subrogated to all (if any) rights of the
Holders against the Issuer in respect of any amounts paid to such Holders by the
Guarantor under this Preferred Securities Guarantee; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any right that it may acquire by way of
subrogation or any indemnity, reimbursement or other agreement, in all cases as
a result of payment under this Preferred Securities Guarantee, if, at the time
of any such payment, any amounts are due and unpaid under this Preferred
Securities Guarantee. If any amount shall be paid to the Guarantor in violation
of the preceding sentence, the Guarantor agrees to hold such amount in trust for
the Holders and to pay over such amount to the Holders.

SECTION 5.7  Independent Obligations
             -----------------------

             The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Preferred
Securities, and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Preferred
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any shares of the Guarantor's capital stock, or (b) make any
payment of principal of or interest or premium, if any, on or repay, repurchase
or redeem any debt securities of the Guarantor that rank pari passu in all
respects with or junior in interest to the Debentures or make any guarantee
payments with respect to any guarantee by the Guarantor of debt securities of
any subsidiary of the Guarantor if such guarantee ranks pari passu with or
junior in interest to the Debentures (other than (a) dividends or distributions
in common stock of the Guarantor, (b) any declaration of a dividend in
connection with the implementation of a Rights Plan (as defined in the
Indenture), or the issuance of stock under any such Rights Plan in the future,
or the redemption or repurchase of any such rights pursuant thereto, (c)
payments under this Preferred Securities Guarantee, (d) purchases of common
stock related to the issuance of common stock or rights under any of the
Guarantor's benefit plans for its directors, officers or employees and (e)
obligations under any dividend reinvestment and stock purchase plan).

SECTION 6.2  Subordination.
             --------------

             The obligations of the Guarantor under this Preferred Securities
Guarantee will constitute unsecured obligations of the Guarantor and will rank
subordinate and junior in right of payments to the Senior Indebtedness and
General Obligations (each as defined in the Indenture) to the extent and in the
manner set forth in the Indenture. The obligations of the Guarantor under this
Preferred Securities Guarantee do not constitute Senior Indebtedness or General
Obligations.

             ---------------------

             The obligations of the Guarantor under this Preferred Securities
Guarantee shall rank pari passu with the obligations of the Guarantor under (i)
any similar Bank One Guarantee (as defined in the Indenture) issued by the
Guarantor on behalf of the holders of preferred or capital securities issued by
any Bank One Capital Trust (as defined in the Indenture) and (ii) the Series A
Guarantee, the Series B Guarantee, the 1997 Guarantee, the 1999 Guarantee, the

                                INDEMNIFICATION

SECTION 8.1  Exculpation
             -----------

             (1)   No Indemnified Person shall be liable, responsible or
     accountable in damages or otherwise to the Guarantor or any Covered Person
     for any loss, damage or claim incurred by reason of any act or omission
     performed or omitted by such Indemnified Person in good faith in accordance
     with this Preferred Securities Guarantee and in a manner that such
     Indemnified Person reasonably believed to be within the scope of the
     authority conferred on such Indemnified Person by this Preferred Securities
     Guarantee or by law, except that an Indemnified Person shall be liable for
     any such loss, damage or claim incurred by reason of such Indemnified
     Person's negligence or willful misconduct with respect to such acts or
     omissions.

             (2)   An Indemnified Person shall be fully protected in relying in
     good faith upon the records of the Guarantor and upon such information,
     opinions, reports or statements presented to the Guarantor by any Person as
     to matters the Indemnified Person reasonably believes are within such other
     Person's professional or expert competence, including information,
     opinions, reports or statements as to the value and amount of the assets,
     liabilities, profits, losses or any other facts pertinent to the existence
     and amount of assets from which Distributions to Holders might properly be
     paid.

SECTION 8.2  Indemnification
             ---------------

             The Guarantor agrees to indemnify each Indemnified Person for, and
to hold each Indemnified Person harmless against, any and all loss, liability,
damage, claim or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against, or
investigating, any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder. The obligation to
indemnify as set forth in this Section 8.2 shall survive the termination of this
Preferred Securities Guarantee or the earlier resignation or removal of the
Preferred Guarantee Trustee.

SECTION 8.3  Compensation and Reimbursement
             ------------------------------

             The Guarantor agrees:

             (1) to pay to the Preferred Guarantee Trustee from time to time
reasonable compensation for all services rendered by it hereunder in such
amounts as the Guarantor and the Preferred Guarantee Trustee shall agree from
time to time (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust); and

             (2) to reimburse the Preferred Guarantee Trustee upon its request
for all reasonable expenses, disbursements and advances incurred or made by the
Preferred Guarantee Trustee in accordance with any provision of this Preferred
Securities Guarantee (including the reasonable compensation and the expenses and
disbursements or its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith.

             The obligations of the Guarantor under this Section 8.3 shall
survive the termination of this Preferred Securities Guarantee or the earlier
resignation or removal of the Preferred Guarantee Trustee.

             To secure the Guarantor's payment obligations in this Section and
in Section 8.2, the Guarantor and the Holders agree that the Preferred Guarantee
Trustee shall have a lien prior to the Preferred Securities on all money or
property held or collection by the Guarantee Trustee. Such lien shall survive
the termination of this Preferred Securities Guarantee.
