            obligations as are specifically set forth in this Capital Securities
            Guarantee, and no implied covenants or obligations shall be read
            into this Capital Securities Guarantee against the Capital Guarantee

            or opinions furnished to the Capital Guarantee Trustee and
            conforming to the requirements of this Capital Securities Guarantee;
            but in the case of any such certificates or opinions that by any

            under a duty to examine the same to determine whether or not they
            conform to the requirements of this Capital Securities Guarantee;

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

            (iii) the Capital Guarantee Trustee shall not be liable with respect
      to any action taken or omitted to be taken by it in good faith in

      method and place of conducting any proceeding for any remedy available to
      the Capital Guarantee Trustee, or exercising any trust or power conferred
      upon the Capital Guarantee Trustee under this Capital Securities
      Guarantee; and

            (iv) no provision of this Capital Securities Guarantee shall require
      the Capital 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 Capital
      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 Capital Securities Guarantee or indemnity, reasonably
      satisfactory to the Capital Guarantee Trustee, against such risk or
      liability is not reasonably assured to it.

      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

            (iii) Whenever, in the administration of this Capital Securities
      Guarantee, the Capital Guarantee Trustee shall deem it desirable that a
      matter be

      proved or established before taking, suffering or omitting any action
      hereunder, the Capital 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.

            (iv) The Capital Guarantee Trustee shall have no duty to see to any
      recording, filing or registration of any instrument (or any rerecording,
      refiling or registration thereof).

            (v) The Capital Guarantee Trustee may consult with counsel, and the
      written 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

      exercise any of the rights or powers vested in it by this Capital
      Securities Guarantee at the request or direction of any Holder, unless

      security and indemnity, reasonably satisfactory to the Capital Guarantee

      complying with such request or direction, including such reasonable
      advances as may be requested by the Capital Guarantee Trustee; provided
      that, nothing contained in this Section 3.2(a)(vi) shall be taken to
      relieve the Capital Guarantee Trustee, upon the occurrence of an Event of
      Default, of its obligation to exercise the rights and powers vested in it
      by this Capital Securities Guarantee.

            (vii) The Capital Guarantee Trustee shall not be bound to make any

      hereunder shall bind the Holders of the Capital Securities, and the
      signature of the Capital 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 Capital Guarantee
      Trustee to so act or as to its compliance with any of the terms and
      provisions of this Capital Securities Guarantee, both of which shall be
      conclusively evidenced by the Capital Guarantee Trustee's or its agent's
      taking such action.

            (x) Whenever in the administration of this Capital Securities

      instructions from the Holders of a Majority in liquidation amount of the
      Capital 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.

deemed to impose any duty or obligation on the Capital 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 Capital 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 Capital Guarantee Trustee shall be construed to be a duty.

SECTION 3.3    Not Responsible for Recitals or Issuance of Guarantee

SECTION 4.1    Capital Guarantee Trustee; Eligibility

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

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

            (ii) be a corporation organized and doing business under the laws of
      the United States of America or any State or Territory 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
      50 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.

            (b) If at any time the Capital Guarantee Trustee shall cease to be
eligible to so act under Section 4.1(a), the Capital Guarantee Trustee shall
immediately resign in the manner and with the effect set out in Section 4.2(c).

            (c) If the Capital Guarantee Trustee has or shall acquire any
"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Capital Guarantee Trustee and Guarantor shall in all respects
comply with the provisions of Section 310(b) of the Trust Indenture Act.

SECTION 4.2   Appointment, Removal and Resignation of Capital Guarantee Trustees

            (a) Subject to Section 4.2(b), the Capital Guarantee Trustee may be
appointed or removed without cause at any time by the Guarantor except if an
Event of Default shall have occurred and be continuing.

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

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

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

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

            (f) Upon termination of this Capital Securities Guarantee or removal
or resignation of the Capital Guarantee Trustee pursuant to this Section 4.2,
the Guarantor shall pay

to the Capital Guarantee Trustee all amounts accrued and owing to such Capital
Guarantee Trustee to the date of such termination, removal or resignation.

                                    GUARANTEE

SECTION 5.1    Guarantee

            The Guarantor irrevocably and unconditionally agrees to pay in full
to the Holders the Guarantee Payments, 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 Capital
Securities Guarantee and of any liability to which it applies or may apply,
presentment, demand for payment, any right to require a proceeding first against
the Issuer or any other Person before proceeding against the Guarantor, protest,
notice of nonpayment, notice of dishonor, notice of redemption and all other
notices and demands.

SECTION 5.3    Obligations Not Affected

            The obligations, covenants, agreements and duties of the Guarantor
under this Capital Securities Guarantee shall in no way be affected or impaired
by reason of the happening from time to time of any of the following:

            (a) 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 Capital Securities to be performed
or observed by the Issuer;

            (b) the extension of time for the payment by the Issuer of all or
any portion of the Distributions, Redemption Price, Liquidation Distribution or
any other sums payable under the terms of the Capital Securities or the
extension of time for the performance of any other obligation under, arising out
of, or in connection with, the Capital Securities;

            (c) 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 Capital Securities, or any
action on the part of the Issuer granting indulgence or extension of any kind;

            (d) 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;

            (e) any invalidity of, or defect or deficiency in, the Capital
Securities;

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

            (g) 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

            (a) The Holders of a Majority in liquidation amount of the Capital
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Capital Guarantee Trustee in respect
of this Capital Securities Guarantee or exercising any trust or power conferred
upon the Capital Guarantee Trustee under this Capital Securities Guarantee.

            (b) If the Capital Guarantee Trustee fails to enforce its rights
under this Capital Securities Guarantee, any Holder may directly institute a
legal proceeding against the Guarantor to enforce the Capital Guarantee
Trustee's rights under this Capital Securities Guarantee, without first
instituting a legal proceeding against the Issuer, the Capital Guarantee Trustee
or any other Person or entity.

            (c) A Holder of Capital Securities may also directly institute a
legal proceeding against the Guarantor to enforce such Holder's right to receive
payment under this Capital Securities Guarantee without first (i) directing the
Capital Guarantee Trustee to enforce the terms of this Capital Securities
Guarantee or (ii) instituting a legal proceeding directly against the Issuer or
any other Person or entity.

SECTION 5.5    Guarantee of Payment

            This Capital 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 of Capital Securities against the Issuer in respect of any amounts paid
to such Holders by the Guarantor under this Capital 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 Capital
Securities Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Capital 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 Capital
Securities, and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Capital
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

                                   ARTICLE VI

                 LIMITATION OF TRANSACTIONS; SUBORDINATION

SECTION 6.1    Limitation of Transactions

            So long as any Capital Securities remain outstanding, if there shall
have occurred any event that would constitute an Event of Default or a Default
under the Declaration, then (a) the Guarantor shall not declare or pay any
dividend on, make any distributions with respect to, or redeem, purchase,
acquire or make a liquidation payment with respect to, any of its capital stock
or make any guarantee payment with respect thereto (other than (i) repurchases,
redemptions or other acquisitions of shares of capital stock of the Guarantor in
connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of employees, officers, directors or
consultants, (ii) as a result of an exchange or conversion of any class or
series of the Guarantor's capital stock for any other class or series of the
Guarantor's capital stock, or (iii) the purchase of fractional interests in
shares of the Guarantor's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged)
and (b) the Guarantor shall not make any payment of interest on, or principal of
(or premium, if any, on), or repay, repurchase or redeem, any debt securities
issued by the Guarantor that rank pari passu with or junior to the Debentures;
provided, however, the Guarantor may declare and pay a stock dividend where the
dividend stock is the same stock as that on which the dividend is being paid.

SECTION 6.2    Subordination

            The obligations of the Guarantor under this Capital Securities
Guarantee will constitute unsecured obligations of the Guarantor and will rank
subordinate and junior in right of

payment to all Senior Indebtedness (as defined in the Indenture) of the
Guarantor to the extent and in the manner set forth in the Indenture with
respect to the Debentures, and the provisions of Article Fourteen of the
Indenture will apply, mutatis mutandis, to the obligations of the Guarantor
hereunder. The obligations of the Guarantor hereunder do not constitute Senior
Indebtedness (as defined in the Indenture) of the Guarantor.

SECTION 6.3       Pari Passu Guarantees

            The obligations of the Guarantor under this Capital Securities
Guarantee shall rank pari passu with the obligations of the Guarantor under (i)
any similar guarantee agreements issued by the Guarantor on behalf of the
holders of preferred or capital securities issued by any Citigroup Trust (as
defined in the Indenture), (ii) the Indenture and the Securities (as defined
therein) issued thereunder, (iii) any expense agreements entered into by the
Guarantor in connection with the offering of preferred or capital securities by
any Citigroup Trust (as defined in the Indenture), and (iv) any other security,
guarantee or other agreement or obligation that is by its terms pari passu with
the Securities (as defined in the Indenture) and, in the case of this clause
(iv) only, (x) is issued with the concurrence or approval of the staff of the
Federal Reserve Bank of New York or the staff of the Board of Governors of the
Federal Reserve System or (y) does not at the time of issuance prevent the
Securities from qualifying for tier 1 capital treatment (irrespective of any
limits on the amount of the Company's tier 1 capital) under the applicable
capital adequacy guidelines, regulations, policies or published interpretations
of the Board of Governors of the Federal Reserve System.

                                   ARTICLE VII

                                   TERMINATION

SECTION 7.1    Termination

            This Capital Securities Guarantee shall terminate upon (i) full
payment of the Redemption Price of all Capital Securities, (ii) the distribution
of the Debentures to the Holders of all of the Capital Securities or (iii) full
payment of the amounts payable in accordance with the Declaration upon
liquidation of the Issuer. Notwithstanding the foregoing, this Capital
Securities Guarantee will continue to be effective or will be reinstated, as the
case may be, if at any time any Holder must restore payment of any sums paid
under the Capital Securities or under this Capital Securities Guarantee.

                                  ARTICLE VIII

                                 INDEMNIFICATION

SECTION 8.1    Exculpation

            (a) 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 Capital
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 Capital 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.

            (b) 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 and who has been selected with
reasonable care by or on behalf of the Guarantor, 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 loss, liability 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 Capital Securities Guarantee.

Holders of not less than a Majority in aggregate liquidation amount (including
the stated amount that would be paid on redemption, liquidation or otherwise,
plus accrued and unpaid Distributions to the date upon which the voting
percentages are determined) of all the outstanding Capital Securities. The
