as Successor Capital Guarantee Trustee. The right, title and interest of the

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

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 Capital
Guarantee Trustee, the Capital Guarantee Trustee shall exercise such of the
rights and powers vested in it by this Capital 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.

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

          (i) 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:

               (A) the duties and obligations of the Capital Guarantee Trustee

          Securities Guarantee, and the Capital Guarantee Trustee shall not be
          liable except for the performance of such duties and 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 Trustee; and

               (B) in the absence of bad faith on the part of the Capital
          Guarantee Trustee, the Capital Guarantee Trustee may conclusively
          rely, as to the truth of the statements and the

                                       6

<PAGE>

          correctness of the opinions expressed therein, upon any certificates
          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 provision hereof
          are specifically required to be furnished to the Capital Guarantee
          Trustee, the Capital Guarantee Trustee shall be 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
     accordance with the direction of the Holders of not less than a Majority in
     liquidation amount of the Capital Securities relating to the time, 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.

     matter be

                                       7

<PAGE>

     proved or established before taking, suffering or omitting any action
     hereunder, the Capital Guarantee Trustee (unless other evidence is herein

     request and conclusively rely upon an Officers' Certificate which, upon
     receipt of such request, shall be promptly delivered by the Guarantor.

     recording, filing or registration of any instrument (or any rerecording,
     refiling or registration thereof).

     written advice or opinion of such counsel with respect to legal matters

     and indemnity, reasonably satisfactory to the Capital Guarantee Trustee,
     against the costs, expenses (including attorneys' fees and expenses and the
     expenses of the Capital 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
     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
     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 Capital Guarantee Trustee,
     in its discretion, may make such further inquiry or investigation into such

          (ix) Any action taken by the Capital Guarantee Trustee or its agents
     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
     Guarantee the Capital Guarantee Trustee shall deem it desirable to receive
     instructions with respect to enforcing any remedy or right or taking any
     other action hereunder, the Capital Guarantee Trustee (i) may request
     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.

          (b) No provision of this Capital Securities Guarantee shall be 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

          The recitals contained in this Guarantee shall be taken as the
statements of the Guarantor, and the Capital Guarantee Trustee does not assume
any responsibility for their correctness. The Capital Guarantee Trustee makes no
representation as to the validity or sufficiency of this Capital Securities
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 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

<PAGE>

     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.

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;

                                       11

<PAGE>

          (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.

<PAGE>

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) repurchases of common stock of the Guarantor pursuant to a
contractually binding requirement to buy stock existing prior to the Event of
Default or Default, (iii) as a result of an exchange or conversion of any class

Guarantor's capital stock, (iv) 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)
or (v) purchase of the Guarantor's capital stock in connection with the
distribution thereof 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 or guarantees 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

                                       13

<PAGE>

          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

by such Indemnified Person in good faith in accordance with this Capital
Securities Guarantee and in a manner that such

                                       14

<PAGE>

Indemnified Person reasonably believed to be within the scope of the authority
conferred on such Indemnified Person by this Capital Securities Guarantee or by

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.

Capital Securities Guarantee may be amended only with the prior approval of the
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
provisions of Section 12.2 of the Declaration with respect to meetings of

affairs.

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

          (i) 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:

               (A) the duties and obligations of the Capital Guarantee Trustee

          liable except for the performance of such duties and 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 Trustee; and

               (B) in the absence of bad faith on the part of the Capital
          Guarantee Trustee, the Capital Guarantee Trustee may conclusively
          rely, as to the truth of the statements and the

<PAGE>

          correctness of the opinions expressed therein, upon any certificates
          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 provision hereof
          are specifically required to be furnished to the Capital Guarantee
          Trustee, the Capital Guarantee Trustee shall be 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

     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

     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.

     proved or established before taking, suffering or omitting any action
     hereunder, the Capital Guarantee Trustee (unless other evidence is herein

     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,

     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

     and indemnity, reasonably satisfactory to the Capital Guarantee Trustee,
     against the costs, expenses (including attorneys' fees and expenses and the
     expenses of the Capital 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

     rights and powers vested in it by this Capital Securities Guarantee.

          (vii) The Capital 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

SECTION 4.2 Appointment, Removal and Resignation of Capital Guarantee Trustees

          (a) Subject to Section 4.2(b), the Capital Guarantee Trustee may be

office until a Successor Capital Guarantee Trustee shall have been appointed or
until its removal or resignation. The Capital Guarantee Trustee may resign from

days after delivery to the Guarantor of an instrument of resignation, the
resigning Capital Guarantee Trustee may petition any court of competent

          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

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;

<PAGE>

          (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

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

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.

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

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.

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

interest on, or principal of (or premium, if any, on), or repay, repurchase or
redeem, any debt securities or guarantees 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

                                       13

<PAGE>

          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

under the Capital Securities or under this Capital Securities Guarantee.

                                  ARTICLE VIII

                                       14

<PAGE>

Indemnified Person reasonably believed to be within the scope of the authority
conferred on such Indemnified Person by this Capital Securities Guarantee or by

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.

the stated amount that would be paid on redemption, liquidation or otherwise,
