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 VI, a Delaware statutory business trust (the "Issuer").

          WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the
"Declaration"), dated as of September 28, 2001, among the trustees of the Issuer
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 20,000,000 preferred securities, having an aggregate
liquidation amount of $500,000,000 (or 23,000,000 preferred securities having an
aggregate liquidation amount of $575,000,000 if the underwriters' over-allotment
option is exercised in full) designated the 7.20% 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.

SECTION 2.7    Event of Default; Notice

          (1)  The Preferred Guarantee Trustee shall, within 90 days after the

                         POWERS, DUTIES AND RIGHTS OF
                          PREFERRED GUARANTEE TRUSTEE

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, the
     Preferred Guarantee Trustee shall enforce this Preferred Securities
     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 wilful
     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

                                       9
<PAGE>

          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.

          (1)  Subject to the provisions of Section 3.1:

               (1)  The Preferred Guarantee Trustee may conclusively rely, and
          shall be fully protected in acting or refraining from acting upon, any
          resolution, certificate, statement, instrument, opinion, report,
          notice, request, direction, consent, order, bond, debenture, note,
          other evidence of indebtedness or other paper or document believed by
          it to be genuine and to have been signed, sent or presented by the
          proper party or parties.

               (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 any

          its selection, and the advice or opinion of such counsel with respect

          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

                                      10
<PAGE>

          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

          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) 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

          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

               (11) The Preferred Guarantee Trustee shall not be liable for any
          action taken, suffered or omitted to be taken by

                                      11

          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.

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

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

          of Columbia authority.  If such corporation publishes reports of
          condition at least annually, pursuant to law or to the requirements of

          the purposes of this Section 4.1(a)(ii), the combined capital and

     during an Event of Default.

          (2)  The Preferred Guarantee Trustee shall not be removed in

     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

     Trustee may resign from office (without need for prior or subsequent
     accounting) by an instrument in writing executed by the Preferred Guarantee

     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

     omissions to act of any Successor Preferred Guarantee Trustee.

SECTION 5.1         Guarantee
                    ---------

          The Guarantor irrevocably and unconditionally agrees to pay in full to
the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by the Issuer), as and when due, regardless of any defense, right of set-
off or counterclaim that the Issuer may have or assert.  The Guarantor's
obligation to make a Guarantee Payment may be satisfied by direct payment of the
required amounts by the Guarantor to the Holders or by causing the Issuer to pay
such amounts to the Holders.

SECTION 5.2         Waiver of Notice and Demand
                    ---------------------------

          The Guarantor hereby waives notice of acceptance of this Preferred

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;

                                      14

     arising out of, or in connection with, the Preferred Securities (other than
     an extension of time for payment of Distributions, Redemption Price,
     Liquidation Distribution or other sum payable that 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
     benefit of creditors, reorganization, arrangement, composition or
     readjustment of debt of, or other similar proceedings affecting, the Issuer
     or any of the assets of the Issuer;

          (5)  any invalidity of, or defect or deficiency in, the Preferred
     Securities;

          (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
                    -----------------

     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

                                      15
<PAGE>

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

          This Preferred Securities Guarantee creates a guarantee of payment and
not of collection.

SECTION 5.6         Subrogation
                    -----------

          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.

SECTION 6.1         Limitation of Transactions
                    --------------------------

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)

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

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 wilful 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

                                      18

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.
