or other action provided or permitted by this Indenture to be given or taken by
Holders shall be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

     (c) The ownership of Securities shall be proved by the Security Register.

or other Act of the Holder of any Security shall bind every future Holder of the

transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

Section 1.5. Notices, Etc., to Trustee and Company.

     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

          (1) the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office, Attention:
     Institutional Trust Group; provided, however, that such instrument will be
     considered properly given if submitted in an electronic format, i.e., by
     facsimile, E-Mail or otherwise, or

          (2) the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Company
     addressed to it at the address of its principal office specified in the
     first paragraph of this instrument or at any other address previously
     furnished in writing to the Trustee by the Company; provided, however, that
     such instrument will be considered properly given if submitted in an
     electronic format, i.e., by facsimile, E-Mail or otherwise.

Section 1.6. Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken-in reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

Section 1.7. Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Indenture by any of
the provisions of the Trust Indenture Act, such required provision shall
control.

invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 1.11. Benefits of Indenture.

     Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors
hereunder, the holders of Senior Indebtedness and the Holders, any benefit or
any legal or equitable right, remedy or claim under this Indenture.

Section 1.12. Governing Law.

     This Indenture and the Securities shall be governed by, and construed and
interpreted in accordance with, the laws of the State of New York, and all
rights and remedies shall be governed by such laws without regard for the
principles of its conflicts of laws.

Section 1.13. Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue for the period from and after
such Interest Payment Date, Redemption Date or Stated Maturity, as the case may
be, except that, if such Business Day is in the next succeeding calendar year,
such payment shall be made on the immediately preceding Business Day, in each
case with the same force and effect as if made on such date.

Section 1.14. Tax Characterization.

     The Company, the Trustee and each Holder of a Security (by acceptance
thereof) agrees to treat the Securities as debt instruments for United States
federal, state and local

                                       15

     [IF THE SECURITY IS TO BE A GLOBAL SECURITY, INSERT - This Security is a
Global Security within the meaning of the Indenture hereinafter referred to and
is registered in the name of a Depositary or a nominee of a Depositary. This
Security is exchangeable for Securities registered in the name of a person other

in the Indenture, and no transfer of this Security (other than a transfer of
this Security as a whole by the Depositary to a nominee of the Depositary or by
a nominee of the Depositary to the Depositary or another nominee of the
Depositary) may be registered except in limited circumstances.

     Unless this Security is presented by an authorized representative of The
Depository Trust Company (55 Water Street, New York, New York) to the issuer or
its agent for registration of transfer, exchange or payment, and any Security
issued is registered in the name of Cede & Co. or such other name as requested

                      [INSERT TITLE OF SERIES OF SECURITY]

     CITIGROUP INC., a Delaware corporation (the "Company," which term includes
any successor corporation under the Indenture hereinafter referred to), for
value received, hereby promises to pay to ___________ or registered assigns, the
principal sum of _________ Dollars ($__________) on ________________, ______,
and to pay interest on said principal sum from ______________, _____, or from
the most recent interest payment date (each such date, an "Interest Payment
Date") to which interest has been paid or duly provided for, [quarterly]
[(subject to deferral as set forth herein)] in arrears on [___________,
___________, ____________ and ___________] of each year commencing
______________, _____, at [If the Security is to bear interest at a fixed rate,
insert -a rate of ___% per annum,] [If the Security is a Floating or Adjustable
Rate Security, insert a rate of ___% per annum [computed-determined] in
accordance with the [insert defined name of Floating or Adjustable Rate
Provision] set forth below] until the principal hereof shall have become due and
payable, and on any overdue principal and premium, if any, and (without
duplication and to the extent that payment of such interest is enforceable under
applicable law) on any overdue installment of interest at the same rate per
annum compounded [quarterly]. The amount of interest payable on any Interest
Payment Date shall be computed on the basis of a 360-day year of twelve 30-day
months. In the event that any date on which interest is payable on this Security
is not a Business Day, then payment of interest payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay), except that, if such Business
Day is in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date. The interest installment so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities, as defined in said Indenture) is registered at the close
of business on the regular record date for such interest installment, which
shall be the close of business on the Business Day next preceding such Interest
Payment Date, [IF PURSUANT TO THE PROVISIONS OF THE INDENTURE THE SECURITIES ARE
NO LONGER REPRESENTED BY A GLOBAL SECURITY -- which shall be the close of
business on the ___ Business Day next preceding such Interest Payment Date.] Any
such interest installment not punctually paid or duly provided for shall
forthwith cease to be payable to the registered Holders on such regular record
date and may be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a special
record date to be fixed by the Trustee for the payment of such defaulted
interest, notice whereof shall be given to the registered Holders of this

                                       17

<PAGE>

series of Securities not less than 10 days prior to such special record date, or
may be paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Securities may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture. Payments on this Global Security will be made to the
Depository Trust Company, or to a successor Depositary. [IF PURSUANT TO THE
PROVISIONS OF THE INDENTURE THE SECURITIES ARE NO LONGER REPRESENTED BY A GLOBAL
SECURITY --The principal of (and premium, if any) and the interest on this
Security shall be payable at the office or agency of the Trustee maintained for
that purpose in any coin or currency of the United States of America that at the
time of payment is legal tender for payment of public and private debts;
provided, however, that payment of interest may be made at the option of the
Company by check mailed to the registered Holder at such address as shall appear
in the Security Register. Notwithstanding the foregoing, so long as the Holder
of this Security is the Institutional Trustee of a Citigroup Trust, the payment
of the principal of (and premium, if any) and interest on this Security will be
made at such place and to such account as may be designated by such
Institutional Trustee.]

     The Securities are not deposits or savings accounts. The Securities are not
insured by the Federal Deposit Insurance Corporation or any other governmental
agency or instrumentality.

     [At this point in the Security Form of any series of Floating or Adjustable
Rate Securities, the text of the Floating or Adjustable Rate Provision relating
thereto should be inserted.]

     The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinate and junior in right of payment to the prior payment
in full of all Senior Indebtedness of the Company, and this Security is issued
subject to the provisions of the Indenture with respect thereto. Each Holder of
this Security, by accepting the same, (a) agrees to and shall be bound by, such
provisions, (b) authorizes and directs the Trustee on his or her behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the
subordination so provided and (c) appoints the Trustee his or her
attorney-in-fact for any and all such purposes. Each Holder hereof, by his or
her acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder of
Senior Indebtedness of the Company, whether now outstanding or hereafter
incurred, and waives reliance by each such holder upon said provisions.

     This Security shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of Authentication hereon shall have been signed by or on behalf of
the Trustee.

     The provisions of this Security are continued on the reverse side hereof
and such continued provisions shall for all purposes have the same effect as
though fully set forth at this place.

Section 2.3. Form of Reverse of Security.

     This Security is one of a duly authorized series of securities of the
Company (herein sometimes referred to as the "Securities"), specified in the
Indenture, all issued or to be issued in one or more series under and pursuant
to an Indenture dated as of _________ __, 2006 (the "Indenture"), duly executed
and delivered between the Company and JPMorgan Chase Bank, N.A., as Trustee (the
"Trustee"), to which Indenture and all indentures supplemental thereto reference
is hereby made for a description of the respective rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the Holders of the Securities. By the terms of the Indenture, the
Securities are issuable in series that may vary as to amount, date of maturity,
rate of interest and in other respects as provided in the Indenture. This series
of Securities is limited in aggregate principal amount to $_________(, plus up
to an additional $__________ aggregate principal amount which may be issued
upon exercise of the over-allotment option contemplated by the Underwriting
Agreement).

     The Company shall have the right to redeem this Security at the option of
the Company, in whole or in part, at any time on or after ____, 20__ (an
"Optional Redemption"), or any time in certain circumstances upon the occurrence
of a Tax Event, an Investment Company Event or a Regulatory Capital Event (as
defined in the Company's Prospectus dated ____, 2006) (each, a "Special Event")
at a redemption price equal to 100% of the principal amount thereof, plus any
accrued and unpaid interest to the date of such redemption (the "Optional
Redemption Price"). Any redemption pursuant to this paragraph will be made upon
not less than 30 days nor more than 60 days notice, or with respect to a
redemption upon a Special Event, within 90 days following the occurrence of such
Special Event, at the Optional Redemption Price. If the Securities are only
partially redeemed by the Company pursuant to an Optional Redemption, the

                                       19

<PAGE>

Securities will be redeemed pro rata or by lot or by any other method utilized
by the Trustee; provided that if, at the time of redemption, the
Securities are registered as a Global Security, the Depositary (as defined
herein) shall determine the principal amount of such Securities held by each
Security Beneficial Owner to be redeemed in accordance with its procedures.

     Any redemption of the Securities of this series, in whole or in part, prior
to the stated maturity date is subject to the prior concurrence or approval of
the Board of Governors of the Federal Reserve System, the Federal Reserve Bank
of New York, or their successor as the Company's primary federal banking
regulator (the "Federal Reserve"), or the staff thereof, (i) if such approval is
then required in order for securities such as the Securities to qualify as tier
1 capital of a bank holding company under applicable capital adequacy
guidelines, regulations, policies, or published interpretations of the Federal
Reserve, or (ii) if the Federal Reserve or its staff has informed the Company
that it must obtain such approval before redeeming the Securities.

     In the event of redemption of this Security in part only, a new Security or
Securities of this series for the unredeemed portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.

     In case an Event of Default and Acceleration, as defined in the Indenture,
shall have occurred and be continuing, the principal of all of the Securities
may be declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the Holders of not less than a majority in aggregate
principal amount of the Securities of each series affected at the time
outstanding, as defined in the Indenture, to execute supplemental indentures for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Indenture or of any supplemental indenture or of
modifying in any manner the rights of the Holders of the Securities; provided,
however, that no such supplemental indenture shall (i) extend the fixed maturity
of any Securities of any series, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, or reduce any
premium payable upon the redemption thereof, without the consent of the Holder
of each Security so affected, or (ii) reduce the aforesaid percentage of
Securities, the Holders of which are required to consent to any such
supplemental indenture, without the consent of the Holders of each Security then
outstanding and affected thereby. The Indenture also contains provisions
permitting the Holders of a majority in aggregate principal amount of the
Securities of any series at the time outstanding affected thereby, on behalf of
all of the Holders of the Securities of such series, to waive any past default
in the performance of any of the covenants contained in the Indenture, or
established pursuant to the Indenture with respect to such series, and its
consequences, except a default in the payment of the principal of or premium, if
any, or interest on any of the Securities of such series. Any such consent or
waiver by the registered Holder of this Security (unless revoked as provided in
the Indenture) shall be conclusive and binding upon such Holder and upon all
future Holders and owners of this Security and of any Security issued in
exchange herefor

                                       20

or in place hereof (whether by registration of transfer or otherwise),
irrespective of whether or not any notation of such consent or waiver is made
upon this Security.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and premium, if any, and
interest on this Security at the time and place and at the rate and in the money
herein prescribed.

     The Company shall have the right at any time during the term of the
Securities and from time to time to extend the interest payment period of such
Securities for up to 40 consecutive quarters (an "Extended Interest Payment
Period"), at the end of which period the Company shall pay all interest then
accrued and unpaid (together with interest thereon at the rate specified for the
Securities to the extent that payment of such interest is enforceable under
applicable law); provided, that no such Extended Interest Payment Period shall
extend beyond the maturity of the Securities; and provided further that during
any such Extended Interest Payment Period (a) the Company 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
Company 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 shares of common stock of the Company pursuant
to a contractually binding requirement to buy stock existing prior to the
commencement of the Extended Interest Payment Period, including under a
contractually binding stock repurchase plan, (iii) as a result of an exchange or
conversion of any class or series of the Company's capital stock for any other
class or series of the Company's capital stock, (iv) the purchase of fractional
interests in shares of the Company's capital stock pursuant to the conversion or
exchange provisions of such capital stock or the security being converted or
exchanged) or (v) the purchase of capital stock of the Company in connection
with the distribution thereof), and (b) except for any partial payments of
Deferred Interest in accordance with the Alternative Payment Mechanism, the
Company 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 Company which rank pari passu with or junior to the Securities.
The foregoing, however, will not apply to any stock dividends paid by the
Company where the dividend stock is the same stock as that on which the dividend
is being paid. Before the termination of any such Extended Interest Payment
Period, the Company may further extend such Extended Interest Payment Period,
provided that such Extended Interest Payment Period together with all such
previous and further extensions thereof shall not exceed 40 consecutive
quarters. At the termination of any such Extended Interest Payment Period and
upon the payment of all accrued and unpaid interest and any additional amounts
then due, the Company may commence a new Extended Interest Payment Period. The
Company may pay current interest at any time with cash from any source.

     Commencing on the earlier of (i) the Fifth Deferral Anniversary and (ii)
the date of any payment of current interest on the Securities during an Extended
Interest Payment

Period, if any Deferred Interest is outstanding, the Company shall be subject to
the Alternative Payment Mechanism, pursuant to which it will continuously use
its commercially reasonable efforts to effect sales of shares of its common
stock, including treasury shares, in an amount that will generate sufficient net
proceeds to enable the Company to pay in full all Deferred Interest on the
Securities then outstanding (subject to the APM Maximum Obligation, if
applicable, and the Share Cap Amount); provided that the Company shall not be
obligated to make offers for or effect sales of its common stock during the
occurrence and continuation of a Market Disruption Event or a Supervisory Event.
The Company's obligation to use commercially reasonable efforts to sell shares
of its common stock to pay all Deferred Interest on the Securities shall resume
at such time as no Market Disruption Event or Supervisory Event exists or is
continuing. The Company may pay Deferred Interest with cash from any source (i)
upon and following the Tenth Deferral Anniversary, (ii) upon the Maturity of the
Securities, (iii) during the occurrence and continuation of a Supervisory Event,
(iv) if the Company has previously sold shares of its common stock up to the
Share Cap Amount and the Company has not increased the Share Cap Amount or (v)
if an Event of Default and Acceleration shall have occurred and be continuing.

     The Holder of this Security, by such holder's acceptance thereof, agrees
that upon any payment or distribution of assets to creditors of the Company upon
any liquidation, dissolution, winding up, reorganization, or in connection with
any insolvency, receivership or proceeding under any bankruptcy law with respect
to the Company, such Holder shall not have a claim for Deferred Interest, to the
extent that the aggregate amount thereof (including Compounded Interest, and
Additional Interest thereon) exceeds 25% of the original principal amount of
such Security.

     As provided in the Indenture and subject to certain limitations therein set
forth, this Security is transferable by the registered Holder hereof on the
Security Register of the Company, upon surrender of this Security for
registration of transfer at the office or agency of the Trustee in the City and
State of New York accompanied by a written instrument or instruments of transfer
in form satisfactory to the Company or the Trustee duly executed by the
registered Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities of authorized denominations and for the
same aggregate principal amount and series will be issued to the designated
transferee or transferees. No service charge will be made for any such transfer,
but the Company or the Trustee may require payment of a sum sufficient to cover
any tax or other governmental charge payable in relation thereto.

     Prior to due presentment for registration of transfer of this Security, the
Company, the Trustee, any paying agent and the Security Registrar may deem and
treat the registered holder hereof as the absolute owner hereof (whether or not
this Security shall be overdue and notwithstanding any notice of ownership or
writing hereon made by anyone other than the Security Registrar) for the purpose
of receiving payment of or on account of the principal hereof and premium, if
any, and interest due hereon and for all other purposes, and neither the Company
nor the Trustee nor any paying agent nor any Security Registrar shall be
affected by any notice to the contrary.

                                       22

<PAGE>

     No recourse shall be had for the payment of the principal of or the
interest on this Security, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

     All Securities of any one series shall be substantially identical except as
to denomination and except as may otherwise be provided in or pursuant to such
Board Resolution and set forth, or determined in the manner provided, in the
Officers' Certificate referred to above or in any such indenture supplemental
hereto.

     If any of the terms of the Securities of a series are established by action
taken pursuant to a Board Resolution, a copy of an appropriate record of such
action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth the terms of the Securities of such series.

Section 3.2. Denominations.

     The Securities of each series shall be issuable in registered form without
coupons and in such denominations as shall be specified as contemplated by
Section 3.1. In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $25 and any integral multiple thereof.

Section 3.3. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman
or a Vice Chairman of the Board, its President, a Vice President, the Chief
Financial Officer, the Chief Accounting Officer, the Treasurer, any Deputy
Treasurer or any Assistant Treasurer, under its corporate seal reproduced
thereon attested by its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established in or
pursuant to one or more Board Resolutions as permitted by Sections 2.1 and 3.1,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive at the time of the initial delivery by the Company of
Securities of such series to the Trustee for authentication, and (subject to
Section 6.1) shall be fully protected in relying upon, an Opinion of Counsel
stating,

          (1) if the form of such Securities has been established by or pursuant
     to Board Resolution as permitted by Section 2.1, that such form has been
     established in conformity with the provisions of this Indenture;

                                       25

<PAGE>

          (2) if the terms of such Securities have been established by or
     pursuant to Board Resolution as permitted by Section 3.1, that such terms
     have been established in conformity with the provisions of this Indenture;
     and

          (3) that such Securities, when authenticated and delivered by or on
     behalf of the Trustee and issued by the Company in the manner and subject
     to any conditions specified in such Opinion of Counsel, will constitute
     valid and legally binding obligations of the Company enforceable in
     accordance with their terms, subject to bankruptcy, insolvency,
     reorganization, and other laws of general applicability relating to or
     affecting the enforcement or creditors' rights and to general equity
     principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture.

Section 3.4. Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon receipt of a Company Order the Trustee shall authenticate
and deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the directors or officers executing such Securities may
determine, as evidenced by their execution of such Securities.

     If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for Securities of that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like aggregate
principal amount of definitive Securities of the same series and of like tenor
of authorized denominations. Until so exchanged, the temporary Securities of any
series shall in all

                                       26

<PAGE>

respects be entitled to the same benefits under this Indenture as definitive
Securities of such series.

Section 3.5. Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities, or of Securities of a particular series, and of
transfers of Securities or of Securities of such series. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

     Subject to Section 3.11, upon surrender for registration of transfer of any
Security of any series at the office or agency of the Company in a Place of
Payment for Securities of that series, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Securities of like tenor of the same series, of
any authorized denominations and of a like aggregate principal amount.

     Subject to Section 3.11, at the option of the Holder, Securities of any
series may be exchanged for other Securities of like tenor of the same series,
of any authorized denominations and of a like aggregate principal amount, upon
surrender of the Securities to be exchanged at such office or agency. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder
making the exchange is entitled to receive.

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

     Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar, duly executed by the Holder thereof or
his attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company or the Trustee may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.4, 9.6 or 11.7 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange any Security of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of such

                                       27

<PAGE>

series selected for redemption under Section 11.3 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.

Section 3.6. Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a protected
purchaser, the Company shall execute and upon its written request the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Security of any series issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

Section 3.7. Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest.

                                       28

<PAGE>

     Interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner. The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security of such series and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this Clause provided. Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 days and not less than 10 days prior to the
     date of the proposed payment and not less than 10 days after the receipt by
     the Trustee of the notice of the proposed payment. The Trustee shall
     promptly notify the Company of such Special Record Date and, in the name
     and at the expense of the Company, shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor to
     be mailed, first-class postage prepaid, to each Holder of Securities of
     such series at his address as it appears in the Security Register, not less
     than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been so mailed, such Defaulted Interest shall be paid to the Persons
     in whose names the Securities of such series (or their respective
     Predecessor Securities) are registered at the close of business on such
     Special Record Date and shall no longer be payable pursuant to the
     following clause (2).

          (2) The Company may make payment of any Defaulted Interest on the
     Securities of any series in any other lawful manner not inconsistent with
     the requirements of any securities exchange on which such Securities may be
     listed, and upon such notice as may be required by such exchange, if, after
     written notice given by the Company to the Trustee of the proposed payment
     pursuant to this Clause, such manner of payment shall be deemed practicable
     by the Trustee in its sole discretion.

     Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

                                       29

<PAGE>

     For the purposes of determining the Holders who are entitled to participate
in any distribution on the Securities in respect of which a Regular Record Date
or a Special Record Date is not otherwise provided for in this Indenture, or for
the purpose of any other action (unless provided for pursuant to Section 3.1),
the Company may from time to time fix a date, not more than 90 days prior to the
date of the payment of distribution or other action, as the case may be, as a
record date for the determination of the identity of the Holders of record for
such purposes.

Section 3.8. Persons Deemed Owners.

     The Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name any Security is registered as the owner of such
Security for the purpose of receiving payment of principal of (and premium, if
any) and (subject to Section 3.7) interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

Section 3.9. Cancellation.

     All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. Unless otherwise directed by a
Company Order, delivery of which must be delivered in a timely manner to prevent
such destruction, all cancelled Securities held by the Trustee shall be
destroyed by it, and the Trustee, upon receipt of a written request of the
Company, shall deliver a certificate of such destruction to the Company.

Section 3.10. Interest.

     (a) Each Security will bear interest at the rate established for the series
of Securities of which such Security is a part pursuant to Section 3.1 (the
"Coupon Rate") from and including the original date of issuance of such Security
until the principal thereof becomes due and payable, and on any overdue
principal and (to the extent that payment of such interest is enforceable under
applicable law) on any overdue installment of interest at the Coupon Rate,
compounded quarterly, payable (subject to the provisions of Article Four)
quarterly in arrears on March 31, June 30, September 30 and December 31 of each
year (or in such other periodic installments on such other dates established as
payment dates for the series of Securities of which such Security is a part
pursuant to Section 3.1) (each, an "Interest Payment Date") commencing on the
date established for the series of Securities of which such Security is a part
pursuant to Section 3.1, to the Person in whose name such Security or any
Predecessor Security is registered, at the close of business on the Regular
Record Date for such interest installment, which, in

                                       30

<PAGE>

respect of any Securities of which the Institutional Trustee of any Citigroup
Trust is the Holder or a Global Security, shall be the close of business on the
Business Day next preceding that Interest Payment Date. Notwithstanding the
foregoing sentence, if the Preferred Securities of a Citigroup Trust are no
longer in book-entry only form or, except if the Securities originally issued to
such Citigroup Trust are held by the Institutional Trustee of such Citigroup
Trust, the Securities of any series are not represented by a Global Security,
the Company may select a Regular Record Date for such interest installment on
such series of Securities which shall be any date more than 14 days but less
than 60 days before an Interest Payment Date.

     (b) The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months and will include the first day
but exclude the last day of such period. Except as provided in the following
sentence, the amount of interest payable for any period shorter than a full
quarterly period for which interest is computed, will be computed on the basis
of the actual number of days elapsed in each 30-day month. In the event that any
date on which interest is payable on the Securities of any series is not a
Business Day, then payment of interest payable on such date will be made on the
next succeeding day that is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

     (c) If, at any time while the Institutional Trustee of a Citigroup Trust is
the Holder of Securities of any series, such Citigroup Trust or such
Institutional Trustee is required to pay any taxes, duties, assessments or
governmental charges of whatever nature (other than withholding taxes) imposed
by the United States, or any other taxing authority, then, in any case, the
Company will pay as additional interest ("Additional Interest") on the
Securities of such series, such additional amounts as shall be required so that
the net amounts received and retained by such Citigroup Trust and/or such
Institutional Trustee, as the case may be, after paying such taxes, duties,
assessments or other governmental charges will be equal to the amounts Citigroup
Trust and/or such Institutional Trustee, as the case may be, would have received
had no such taxes, duties, assessments or other government charges been imposed.

Section 3.11. Form and Payment.

     Except as provided in Section 3.12, the Securities of each series shall be
issued in fully registered certificated form without interest coupons. Principal
and interest on the Securities issued in certificated form will be payable, the
transfer of such Securities will be registrable, and such Securities will be
exchangeable, for Securities of the same series bearing identical terms and
provisions at the office or agency of the Trustee; provided, however, that
payment of interest may be made at the option of the Company by check mailed to
the Holders of such Securities at such address as shall appear in the Security
Register. Notwithstanding the foregoing, so long as the Holder of all Securities
of any series is the Institutional Trustee of any Citigroup Trust, the payment
of the principal of and interest (including Compounded Interest and Additional
Interest, if any) on Securities

                                       31

<PAGE>

of such series will be made at such place and to such account as may be
designated by the Institutional Trustee.

Section 3.12. Global Securities.

     (a) In connection with Dissolution Event with respect to any Citigroup
Trust,

          (i) the Securities in non book-entry certificated form held by such
Citigroup Trust, or its Institutional Trustee, will be presented to the Trustee
by the Institutional Trustee of such Citigroup Trust in exchange for a Global
Security in an aggregate principal amount equal to the aggregate principal
amount of all outstanding Securities of the series issued to such Citigroup
Trust, to be registered in the name of the Depositary, or its nominee, and
delivered by the Trustee to the Depositary for crediting to the accounts of its
participants pursuant to the instructions of the Regular Trustees of the
relevant Citigroup Trust. The Company upon any such presentation shall execute a
Global Security in such aggregate principal amount and deliver the same to the
Trustee for authentication and delivery in accordance with this Indenture.
Payments on any Securities issued as a Global Security will be made to the
Depositary; and

          (ii) if any Preferred Securities of a Citigroup Trust are held in non
book-entry certificated form, the Securities in non book-entry certificated form
held by such Citigroup Trust, or its Institutional Trustee, may be presented to
the Trustee by the Institutional Trustee of such Citigroup Trust and any
Preferred Security Certificate which represents Preferred Securities of such
Citigroup Trust other than Preferred Securities held by the Depositary or its
nominee ("Non Book-Entry Preferred Securities") will be deemed to represent
Securities presented to the Trustee by such Institutional Trustee having an
aggregate principal amount equal to the aggregate liquidation amount of the Non
Book-Entry Preferred Securities until such Preferred Security Certificates are
presented to the Security Registrar for transfer or reissuance at which time
such Preferred Security Certificates will be cancelled and a Security,
registered in the name of the holder of the Preferred Security Certificate or
the transferee of the holder of such Preferred Security Certificate, as the case
may be, with an aggregate principal amount equal to the aggregate liquidation
amount of the Preferred Security Certificate cancelled, will be executed by the
Company and delivered to the Trustee for authentication and delivery in
accordance with this Indenture. On issue of such Securities, Securities with an
equivalent aggregate principal amount that were presented by the Institutional
Trustee to the Trustee will be deemed to have been cancelled.

     (b) A Global Security may be transferred, in whole but not in part, only to
another nominee of the Depositary, or to a successor Depositary selected or
approved by the Company or to a nominee of such successor Depositary.

     (c) If at any time the Depositary notifies the Company that it is unwilling
or unable to continue as Depositary for any series of Securities or if at any
time the Depositary for such series shall no longer be registered or in good
standing under the Exchange Act, or other applicable statute or regulation, and
a successor Depositary for such series is not appointed by the Company within 90
days after the Company receives

                                       32

<PAGE>

such notice or becomes aware of such condition, as the case may be, the Company
will execute, and, subject to this Article III, the Trustee, upon written notice
from the Company, will authenticate and deliver the Securities of such series in
definitive registered form without coupons, in authorized denominations, and in
an aggregate principal amount equal to the principal amount of the Global
Security in exchange for such Global Security. In addition, the Company may at
any time determine that the Securities of any series shall no longer be
represented by a Global Security. In such event the Company will execute, and
subject to Section 3.5, the Trustee, upon receipt of an Officers Certificate
evidencing such determination by the Company, will authenticate and deliver the
Securities of such series in definitive registered form without coupons, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security for such series in exchange for such
Global Security. Upon the exchange of the Global Security for such Securities in
definitive registered form without coupons, in authorized denominations, the
Global Security shall be cancelled by the Trustee. Such Securities in definitive
registered form issued in exchange for the Global Security shall be registered
in such names and in such authorized denominations as the Depositary, pursuant
to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Securities to the
Depositary, for delivery to the Persons in whose names such Securities are so
registered.

have no liability in respect of any term, condition or limitation set forth in
any such covenant (to the extent so specified in the case of Section 5.7(d)),
whether directly or indirectly by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document, but the remainder of this
Indenture and the Securities of such series shall be unaffected thereby.

Section 4.4. Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to application of either Section 4.2
or 4.3 to the Outstanding Securities:

faith and credit ("U.S. Government Obligations"), maturing as to principal and
interest, if any, at such times and in such amounts as will insure the
availability of cash, or (iii) a combination thereof, in each case sufficient,
in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge, the principal of and interest, if any, on all Securities of such
series on each date that such principal or interest, if any, is due and payable;

     (b) in the case of Defeasance under Section 4.2, the Company has delivered
to the Trustee an Opinion of Counsel based on the fact that (x) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (y), since the date hereof, there has been a change in the applicable
United States federal income tax law, in either case to the effect that, and
such opinion shall confirm that, the Holders of the Securities of such series
will not recognize income, gain or loss for United States federal income tax
purposes as a result of such deposit, Defeasance and discharge and will be
subject to United States federal income tax on the same amount and in the same
manner and at the same times, as would have been the case if such deposit,
Defeasance and discharge had not occurred;

     (c) in the case of Covenant Defeasance under Section 4.3, the Company has
delivered to the Trustee an Opinion of Counsel to the effect that, and such
opinion shall confirm that, the Holders of the Securities of such series will
not recognize income, gain or loss for United States federal income tax purposes
as a result of such deposit and Covenant Defeasance and will be subject to
United States federal income tax on the same amount and in the same manner and
at the same times, as would have been the case if such deposit and Covenant
Defeasance had not occurred;

     (d) such Defeasance or Covenant Defeasance will not result in a breach or
violation of, or constitute a default under, any agreement or instrument to
which the Company is a party or by which it is bound; and

     (e) the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent contemplated by this provision have been complied with.

Section 4.5. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 10.3, all money
and U.S. Government Obligations deposited with the Trustee pursuant to Section
4.4 shall be held in trust, and such money and all money from such U.S.
Government Obligations shall be applied by it, in accordance with the provisions
of the Securities and this Indenture, to the payment, either directly or through
any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of

                                       36

     If the Trustee is unable to apply any money or Government Obligations in
accordance with Section 4.4 by reason of any legal preceding or by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to Section 4.4, until such time as the Trustee or
Paying Agent is permitted to apply all such money or Government Obligations in
accordance with Section 4.4; provided that, if the Company has made any payment
of principal or interest on the Securities of any series because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money or
Government Obligations held by the Trustee or Paying Agent.

                                    ARTICLE V

                                    REMEDIES

Section 5.1. Events of Default and Acceleration.

     The term "Event of Default and Acceleration" as used in this Indenture with
respect to Securities of any series shall mean one of the following described
events (whatever the reason for such Event of Default and Acceleration and
whether it shall be voluntary or involuntary or be effected by operation of law
or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):

     (a) failure to pay in full interest accrued upon any Security of that
series upon the conclusion of a period consisting of 40 consecutive quarters,
commencing with the earliest quarter for which interest (including Deferred
Interest) has not been paid in full, and continuance of such failure to pay for
a period of 30 days;

     (b) the entry by a court having jurisdiction in the premises of a decree or
order for relief in respect of the Company in an involuntary case under the
Federal bankruptcy code, as now or hereafter constituted, or any other
applicable Federal or State bankruptcy, insolvency or other similar law now or
hereafter in effect, or appointing a receiver,

                                       37

<PAGE>

liquidator, assignee, custodian, trustee or sequestrator (or similar official)
of the Company or for substantially all of its property, or ordering the
winding-up or liquidation of its affairs and such decree or order shall remain
unstayed and in effect for a period of 90 consecutive days; or

     (c) the commencement by the Company of a voluntary case under the Federal
bankruptcy code, as now or hereafter constituted, or any other applicable
Federal or State bankruptcy, insolvency or other similar law now or hereafter in

appointment of or taking possession by a receiver, liquidator, assignee,
trustee, custodian or sequestrator (or similar official) of the Company or for
substantially all of its property, or the making by it of an assignment for the
benefit of creditors.

Section 5.2. Acceleration of Maturity.

     If any one or more Event of Default and Acceleration shall occur with
respect to Securities of any series at the time Outstanding, then, and in each
and every such case, during the continuance of any such Event of Default and
Acceleration, the Trustee or the Holders of 25% or more in principal amount of
the Securities of such series then Outstanding may declare the principal amount
of all the Securities of such series then Outstanding, if not then due and
payable, to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by such Holders), and upon any such
declaration the same shall become and be immediately due and payable, anything
in this Indenture or in the Securities of such series contained to the contrary
notwithstanding. This provision, however, is subject to the condition that, if
at any time after the principal of all the Securities of such series shall have
been so declared to be due and payable, all arrears of interest, if any, upon
all the Securities of such series (with interest, to the extent that interest
thereon shall be legally enforceable, on any overdue installment of interest at
the rate borne by the Securities of such series) and all amounts owing the
Trustee and any predecessor trustee hereunder under Section 6.7 and all other
sums payable under this Indenture (except the principal of the Securities of
such series which would not be due and payable were it not for such declaration)
shall be paid by the Company, and every other Default under this Indenture,
other than the non-payment of the principal of Securities of that series which
have become due solely by such declaration of acceleration, shall have been made
good to the reasonable satisfaction of the Trustee or of the Holders of a
majority in principal amount of the Securities of such series then Outstanding,
or provision deemed by the Trustee or by such Holders to be adequate therefor
shall have been made, then and in every such case the Holders of a majority in
principal amount of the Securities of such series then Outstanding may, on
behalf of the Holders of all the Securities of such series, waive the Event of
Default and Acceleration by reason of which the principal of the Securities of
such series shall have been so declared to be due and payable and may rescind
and annul such declaration and its consequences; but no such waiver, rescission
or annulment shall extend to or affect any subsequent Default or impair any
right consequent thereon. Any declaration by the Trustee pursuant to this
Section 5.2 shall be by written notice to the Company, and any

                                       38

<PAGE>

declaration or waiver by the Holders of Securities of any series pursuant to
this Section 5.2 shall be by written notice to the Company and the Trustee.

Section 5.3. Collection of Indebtedness and Suits for Enforcement by
Trustee.

     If the Company shall fail for a period of 30 days to pay any installment of
interest on the Securities of any series or shall fail to pay the principal of
and premium, if any, on any of the Securities of such series when and as the
same shall become due and payable, whether at maturity, or by call for
redemption by declaration as authorized by this Indenture or otherwise, then,
upon demand of the Trustee, the Company will pay to the Trustee for the benefit
of the Holders of Securities of such series then Outstanding the whole amount
which then shall have become due and payable on any such Security, with interest
on the overdue principal and premium, if any, and (so far as the same may be
legally enforceable) on the overdue installments of interest at the rate borne
by the Securities of such series, and all amounts owing the Trustee and any
predecessor trustee hereunder under Section 6.7.

     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceeding at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor upon the
Securities of such series, and collect the moneys adjudged or decreed to be
payable out of the property of the Company or any other obligor upon the
Securities of such series, wherever situated, in the manner provided by law.
Every recovery of judgment in any such action or other proceeding, subject to
the payment to the Trustee of all amounts owing the Trustee and any predecessor
trustee hereunder under Section 6.7, shall be for the ratable benefit of the
Holders of such series of Securities which shall be the subject of such action
or proceeding. All rights of action upon or under any of the Securities or this
Indenture may be enforced by the Trustee without the possession of any of the
Securities and without the production of any thereof at any trial or any
proceeding relative thereto.

     If a Default, of which a Responsible Officer of the Trustee has actual
knowledge, with respect to any series of Securities occurs and is continuing,
the Trustee may in its discretion proceed to protect and enforce its rights and
the rights of the Holders of Securities of such series by such appropriate
judicial proceedings as the Trustee shall deem most effectual to protect and
enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture, or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy.

Section 5.4. Trustee to File Claims As Attorney-In-Fact.

     The Trustee is hereby appointed, and each and every Holder of the
Securities, by receiving and holding the same, shall be conclusively deemed to
have appointed the

                                       39

<PAGE>

Trustee, the true and lawful attorney-in-fact of such Holder, with authority to
make or file (whether or not the Company shall be in default in respect of the
payment of the principal of, or interest on, any of the Securities), in its own
name and as trustee of an express trust or otherwise as it shall deem advisable,
in any receivership, insolvency, liquidation, bankruptcy, reorganization or
other judicial proceeding relative to the Company or any other obligor upon the
Securities or to their respective creditors or property, any and all claims,
proofs of claim, proofs of debt, petitions, consents, other papers and documents
and amendments of any thereof, as may be necessary or advisable in order to have
the claims of the Trustee and any predecessor trustee hereunder and of the
Holders of the Securities allowed in any such proceeding and to collect and
receive any moneys or other property payable or deliverable on any such claim,
and to execute and deliver any and all other papers and documents and to do and
perform any and all other acts and things, as it may deem necessary or advisable
in order to enforce in any such proceeding any of the claims of the Trustee and
any predecessor trustee hereunder and of any of such Holders in respect of any
of the Securities; and any receiver, assignee, trustee, custodian or debtor in
any such proceeding is hereby authorized, and each and every taker or Holder of
the Securities, by receiving and holding the same, shall be conclusively deemed
to have authorized any such receiver, assignee, trustee, custodian or debtor, to
make any such payment or delivery only to or on the order of the Trustee, and to
pay to the Trustee any amount due it and any predecessor trustee hereunder under
Section 6.7; provided, however, that nothing herein contained shall be deemed to
authorize or empower the Trustee to consent to or accept or adopt, on behalf of
any Holder of Securities, any plan of reorganization or readjustment of the
Company affecting the Securities or the rights of any Holder thereof, or to
authorize or empower the Trustee to vote in respect of the claim of any Holder
of any Securities in any such proceeding.

Section 5.5. Application of Money Collected.

     Any moneys collected by the Trustee with respect to a series of Securities
under this Article Five shall be applied in the order following, at the date or
dates fixed by the Trustee for the distribution of such moneys, upon
presentation of the several Securities, and stamping thereon the payment, if
only partially paid, and upon surrender thereof, if fully paid:

          First: To the payment of all amounts due to the Trustee and any
     predecessor trustee hereunder under Section 6.7.

          Second: Subject to Article Fourteen, in case the principal of the
     Outstanding Securities of such series shall not have become due and be
     unpaid, to the payment of interest on the Securities of such series, in the
     order of the maturity of the installments of such interest, with interest
     (to the extent that such interest has been collected by the Trustee) upon
     the overdue installments of interest at the rate borne by such Securities,
     such payments to be made ratably to the Persons entitled thereto.

          Third: Subject to Article Fourteen, in case the principal of the
     Outstanding Securities of such series shall have become due, by declaration
     or otherwise, to

                                       40

<PAGE>

     the payment of the whole amount then owing and unpaid upon the Securities
     of such series for principal and premium, if any, and interest, with
     interest on the overdue principal and premium, if any, and (to the extent
     that such interest has been collected by the Trustee) upon overdue
     installments of interest at the rate borne by the Securities of such
     series, and in case such moneys shall be insufficient to pay in full the
     whole amounts so due and unpaid upon the Securities of such series, then to
     the payment of such principal and premium, if any, and interest without
     preference or priority of principal and premium, if any, over interest, or
     of interest over principal and premium, if any, or of any installment of
     interest over any other installment of interest, or of any Security of such
     series over any other Security of such series, ratably to the aggregate of
     such principal and premium, if any, and accrued and unpaid interest.

Section 5.6. Control by Holders; Waiver of Past Default.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee hereunder, or of exercising any trust or
power hereby conferred upon the Trustee with respect to the Securities of such
series; provided, however, that the Trustee shall have the right to decline to
follow any such direction if the Trustee being advised by counsel determines
that the action so directed may not lawfully be taken or would be unduly
prejudicial to Holders not joining in such direction or would involve the
Trustee in personal liability. Prior to any declaration accelerating the
maturity of the Securities of any series, the Holders of a majority in aggregate
principal amount of such series of Outstanding Securities may on behalf of the
Holders of all of the Securities of such series waive any past default hereunder
and its consequences except a default not theretofore cured in the payment of
interest or any premium on or the principal of the Securities of such series or
in respect of any covenant or provision hereof which under Article Nine cannot
be modified or waived without the consent of the Holder of each Outstanding
Security of each series affected thereby; provided, however, that if the
Securities of such series are held by a Citigroup Trust or a trustee of such
trust, such waiver or modification to such waiver shall not be effective until
the holders of Trust Securities representing a majority in liquidation
preference of Trust Securities of the applicable Citigroup Trust shall have
consented to such waiver or modification to such waiver; provided further, that
if the consent of the Holder of each Outstanding Security is required, such
waiver shall not be effective until each holder of the Trust Securities of the
applicable Citigroup Trust shall have consented to such waiver. Upon any such
waiver the Company, the Trustee and the Holders of the Securities of such series
shall be restored to their former positions and rights hereunder, respectively,
but no such waiver shall extend to any subsequent or other default or impair any
right consequent thereon. Whenever any default hereunder shall have been waived
as permitted by this Section 5.6, said default shall for all purposes of the
Securities of such series and this Indenture cease to exist, and any Default or
Event of Default and Acceleration arising therefrom shall be deemed to have been
cured and to be not continuing.

Section 5.7. Limitation on Suits; Default.

     No Holder of any Security of any series shall have any right to institute
any action, suit or proceeding at law or in equity for the execution of any
trust hereunder or for the appointment of a receiver or for any other remedy
hereunder, in each case with respect to a Default with respect to such series of
Securities, unless such Holder previously shall have given to the Trustee
written notice of the happening of one or more of the Defaults herein specified
with respect to such series of Securities, and unless also the Holders of 25% or
more in principal amount of the Securities of such series then Outstanding shall
have requested the Trustee in writing to take action in respect of the matter
complained of, and unless also there shall have been offered to the Trustee
security and indemnity satisfactory to it against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee, for 60 days
after receipt of such notification, request and offer of indemnity, shall have
neglected or refused to institute any such action, suit or proceeding; and such
notification, request and offer of indemnity are hereby declared in every such
case to be conditions precedent to any such action, suit or proceeding by any
Holder of any Security of such series; it being understood and intended that no
one or more of the Holders of Securities of such series shall have any right in
any manner whatsoever by his or their action to enforce any right hereunder,
except in the manner herein provided, and that every action, suit or proceeding
at law or in equity shall be instituted, had and maintained in the manner herein
provided and for the equal and ratable benefit of all Holders of the Outstanding
Securities of such series; provided, however, that nothing contained in this
Indenture or in the Securities of such series shall affect or impair the
obligation of the Company, which is absolute and unconditional, to pay the
principal of, and premium, if any, and interest on the Securities of such series
to the respective Holders of such Securities at the respective due dates in such
Securities stated, or affect or impair the right, which is also absolute and
unconditional, of such Holders to institute suit to enforce the payment thereof.

     The following events shall be "Defaults" with respect to any series of
Securities under this Indenture:

     (a)  an Event of Default and Acceleration with respect to such series
          specified in Section 5.1; or

     (b)  the failure of the Company to pay any installment of interest on any
          Security of such series, when and as the same shall become payable,
          which failure shall have continued unremedied for a period of 30 days,
          it being understood that the occurrence of an Extended Interest
          Payment Period in accordance with the terms of such Security will not
          constitute such a default; or

     (c)  the failure of the Company to pay the principal of (and premium, if
          any, on) any Security of such series, when and as the same shall
          become payable, whether at maturity as therein expressed, by call for
          redemption,

                                       42

<PAGE>

          by declaration as authorized by this Indenture or otherwise, whether
          or not permitted by Article Fourteen; or

     (d)  the failure of the Company, subject to the provisions of Section 8.1,
          to observe and perform any other of the covenants or agreements on the
          part of the Company contained in this Indenture (including any
          indenture supplemental hereto) (other than a covenant or agreement
          which has been expressly included in this Indenture solely for the
          benefit of a series of Securities other than that series), which
          failure shall not have been remedied for a period of 90 days after
          written notice shall have been given to the Company by the Trustee or
          shall have been given to the Company and the Trustee by Holders of 25%
          or more in aggregate principal amount of the Securities of such series
          then Outstanding, specifying such failure and requiring the Company to
          remedy the same; or

     (e)  in the event Securities of a series are issued and sold to a Citigroup
          Trust or a trustee of such trust in connection with the issuance of
          Trust Securities by such Citigroup Trust, such Citigroup Trust shall
          have voluntarily or involuntarily dissolved, wound-up its business or
          otherwise terminated its existence except in connection with (i) the
          distribution of Securities to holders of Trust Securities in
          liquidation or redemption of their interests in such Citigroup Trust
          upon a Special Event with respect to such Citigroup Trust, (ii) the
          redemption of all of the outstanding Trust Securities of such
          Citigroup Trust or (iii) certain mergers, consolidations or
          amalgamations, each as permitted by the Declaration of such Citigroup
          Trust; or

     (f)  any other Default provided with respect to Securities of that series.

Section 5.8. Costs and Attorneys' Fees in Legal Proceedings.

     All parties to this Indenture and the Holders of the Securities agree that
the court may in its discretion require, in any action, suit or proceeding for
the enforcement of any right or remedy under this Indenture, or in any action,
suit or proceeding against the Trustee for any action taken or omitted by it as
Trustee, the filing by any party litigant in such action, suit or proceeding of
an undertaking to pay the costs of such action, suit or proceeding, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such action, suit or proceeding,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; provided, however, that the provisions of this Section 5.8
shall not apply to any action, suit or proceeding instituted by the Trustee, to
any action, suit or proceeding instituted by any one or more Holders of
Securities holding in the aggregate more than 10% in principal amount of the
Outstanding Securities, or to any action, suit or proceeding instituted by any
Holder of Securities for the enforcement of the payment of the principal of or
premium, if any, or the interest on, any of the Securities, on or after the
respective due dates expressed in such Securities.

Section 5.9. Remedies Cumulative.

     Except as provided in the last sentence of Section 3.6, no remedy herein
conferred upon or reserved to the Trustee or to the Holders of Securities of any
series is intended to be exclusive of any other remedy or remedies, and each and
every remedy shall be cumulative and shall be in addition to every other remedy
given hereunder or now or hereafter existing at law or in equity or by statute.
No delay or omission of the Trustee or of any Holder of the Securities of any
series to exercise any right or power accruing upon any Default shall impair any
such right or power or shall be construed to be a waiver of any such Default or
an acquiescence therein; and every power and remedy given by this Article Five
to the Trustee and to the Holders, respectively, may be exercised from time to
time and as often as may be deemed expedient by the Trustee or by the Holders,
as the case may be. In case the Trustee or any Holder of Securities shall have
proceeded to enforce any right under this Indenture and the proceedings for the
enforcement thereof shall have been discontinued or abandoned because of waiver
or for any other reason or shall have been adjudicated adversely to the Trustee
or to such Holder, then and in every such case the Company, the Trustee and the
Holders shall severally and respectively be restored to their former positions
and rights hereunder and thereafter all rights, remedies and powers of the
Trustee and the Holders shall continue as though no such proceedings had been
instituted, except as to any matters so waived or adjudicated.

Section 5.10. Waiver of Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no law had been enacted.

Section 5.11. Limitation on Claim for Certain Deferred Interest in Bankruptcy.

     Notwithstanding anything to the contrary in this Indenture, each Holder of
a Security, by such holder's acceptance thereof, agrees that upon any payment or
distribution of assets to creditors of the Company upon any liquidation,
dissolution, winding up, reorganization, or in connection with any insolvency,
receivership or proceeding under any bankruptcy law with respect to the Company,
such Holder shall not have a claim for Deferred Interest, to the extent that the
aggregate amount thereof (including Compounded Interest and Additional Interest
thereon) exceeds 25% of the original principal amount of such Security.

                                   ARTICLE VI

                                   THE TRUSTEE

Section 6.1. Certain Duties and Responsibilities.

     (a) Except during the continuance of a Default;

          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and

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

     (b) In case a Default with respect to any series of Securities, of which a
Responsible Officer of the Trustee has actual knowledge, has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

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

          (1) this subsection shall not be construed to limit the effect of
     subsection (a) of this Section;

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

          (3) the 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 a majority in principal amount of the Outstanding
     Securities of any series determined as provided in Section 5.6, relating to
     the time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any trust or power conferred upon
     the Trustee, under this Indenture with respect to the Securities of such
     series; and

          (4) no provision of this Indenture shall require the Trustee to expend
     or risk its own funds or otherwise incur any financial liability in the
     performance of any of its duties hereunder, or in the exercise of any of
     its rights or powers, if it

                                       45

<PAGE>

     shall have reasonable grounds for believing that repayment of such funds or
     indemnity, reasonably satisfactory to it, against such risk or liability is
     not reasonably assured to it.

     (d) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conductor affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

Section 6.2. Notice of Defaults.

     Within 90 days after the occurrence of any Default hereunder with respect
to Securities of any series, the Trustee shall transmit by mail to all Holders
of Securities of such series, as their names and addresses appear in the
Security Register, notice of such Default hereunder actually known to a
Responsible Officer of the Trustee, unless such Default shall have been cured or
waived; provided that, except in the case of a Default in the payment of the
principal of (or premium, if any) or interest on any Security of such series,
the Trustee shall be protected in withholding such notice if and so long as a
Responsible Officer of the Trustee in good faith determines that the withholding
of such notice is in the interest of the Holders of Securities of such series;
and provided, further, that in the case of any Default of the character
specified in Section 5.7(e) with respect to Securities of such series, no such
notice to Holders shall be given until at least 30 days after the occurrence
thereof.

Section 6.3. Certain Rights of Trustee.

     Subject to the provisions of Section 6.1

     (a) the 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 or presented by the proper
party or parties;

     (b) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order, and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

     (c) whenever in the administration of this Indenture the Trustee shall deem
it desirable that a matter be proved or established prior to taking, suffering
or omitting any action hereunder, the Trustee (unless other evidence be herein
specifically prescribed) may, in the absence of bad faith on its part,
conclusively rely upon an Officers' Certificate;

     (d) the Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel 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 reliance thereon;

                                       46

<PAGE>

     (e) the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Holders pursuant to this Indenture, unless such Holders shall have offered
to the Trustee security or indemnity, reasonably satisfactory to it, against the
costs, expenses and liabilities which might be incurred by it in compliance with
such request or direction;

     (f) the 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
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;
and

     (g) the Trustee may execute any of the trust or powers hereunder or perform
any duties hereunder either directly or by or through agents or attorneys and
the 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.

     (h) the Trustee shall not be charged with knowledge of any Default or Event
of Default and Acceleration with respect to the Securities, unless either (1) a
Responsible Officer shall have actual knowledge of such Default or Event of
Default and Acceleration or (2) written notice of such Default or Event of
Default and Acceleration shall have been given to the Trustee by the Company or
by any Holder of the Securities; and

     (i) the permissive rights of the Trustee enumerated herein shall not be
construed as duties.

Section 6.4. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee or any Authenticating Agent assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities. The Trustee or any
Authenticating Agent shall not be accountable for the use or application by the
Company of Securities or the proceeds thereof.

Section 6.5. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
6.8 and 6.13, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

                                       47

<PAGE>

Section 6.6. Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

Section 6.7. Compensation and Reimbursement.

     The Company agrees

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

          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision
     of this Indenture (including the reasonable compensation and the expenses
     and disbursements of its agents, nominees, custodians and counsel), except
     any such expense, disbursement or advance as may be attributable to its
     negligence or bad faith; and

          (3) to indemnify the Trustee for, and to hold it 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 trust hereunder, including the costs and expenses of
     defending itself against any claim or liability in connection with the
     exercise or performance of any of its powers or duties hereunder.

     As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the benefit of Holders of particular Securities. The obligations of
the Company under this Section shall survive the removal or resignation of the
Trustee and the satisfaction and discharge of this Indenture.

     When the Trustee incurs any expenses or renders any services after the
occurrence of an Event of Default and Acceleration specified in Section 5.1(b)
or Section 5.1(c), such expenses and the compensation for such services are
intended to constitute expenses of administration under the United States
Bankruptcy Code (Title 11 of the United States Code) or any similar federal or
state law for the relief of debtors.

Section 6.8. Disqualification; Conflicting Interests.

     The Trustee shall be subject to the provisions of Section 310(b) of the
Trust Indenture Act of 1939 during the period of time provided for therein. In
determining

                                       48

<PAGE>

whether the Trustee has a conflicting interest as defined in Section 310(b) of
the Trust Indenture Act of 1939 with respect to the Securities of any series,
there shall be excluded for purposes of the conflicting interest provisions of
such Section 310(b) the Securities of every other series issued under this
Indenture. Nothing herein shall prevent the Trustee from filing with the
Commission the application referred to in the second to last paragraph of
Section 310(b) of the Trust Indenture Act of 1939.

Section 6.9. Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000 and subject to supervision or examination by Federal or
State authority. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervision or
examining authority, then for the purposes of this Section, 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. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

Section 6.10. Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 6.11 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

     (c) The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

     (d) If at any time:

          (1) the Trustee shall fail to comply with Section 6.8(a) after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.9 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or

                                       49

<PAGE>

          (3) the Trustee shall become incapable of acting or shall be adjudged
     bankrupt or insolvent or a receiver of the Trustee or of its property shall
     be appointed or any public officer shall take charge or control of the
     Trustee or of its property or affairs for the purpose of rehabilitation,
     conservation or liquidation, then, in any such case, (i) the Company, by a
     Board Resolution, may remove the Trustee with respect to all Securities, or
     (ii) subject to Section 5.8, any Holder who has been a bona fide Holder of
     a Security for at least six months may, on behalf of himself and all others
     similarly situated, petition any court of competent jurisdiction for the
     removal of the Trustee with respect to all Securities and the appointment
     of a successor Trustee or Trustees.

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 6.11. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such
series delivered to the Company and the retiring Trustee, the successor Trustee
so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 6.11, become the
successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
required by Section 6.11, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.

Section 6.11. Acceptance of Appointment by Successor.

     (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an

become effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder.

respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to the Securities of all
series for which it is the Trustee hereunder, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any mist or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,

such retiring Trustee hereunder with respect to the Securities of that or those

     (d) No successor Trustee shall accept its appointment unless at the time of

Section 6.12. Merger, Conversion, Consolidation or Succession to Business.

     Any corporation or association into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation or
association resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any corporation or association to which all or
substantially all of the corporate trust business of the Trustee may be sold or
otherwise transferred, shall be the successor trustee hereunder without any
further act. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such authentication and
deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.

Section 6.13. Preferential Collection of Claims Against Company.

     The Trustee shall comply with the Trust Indenture Act Section 311(a),
excluding any creditor relationship listed in the Trust Indenture Act Section
311(b). A Trustee who has resigned or been removed shall be subject to the Trust
Indenture Act Section 311(a) to the extent indicated therein.

Section 6.14. Appointment of Authenticating Agent.

     At any time when any of the Securities remain Outstanding the Trustee may
appoint an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon exchange, registration of
transfer or partial redemption thereof or pursuant to Section 3.6, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

                                       52

<PAGE>

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment by first-class mail, postage prepaid, to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve, as
their names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

     The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon an
alternative certificate of authentication in the following form:

     interest thereon is payable, or impair the right to institute suit for the
     enforcement of any such payment on or after the Stated Maturity thereof
     (or, in the case of redemption, on or after the Redemption Date), or modify
     the provisions of this Indenture with respect to the subordination of the
     Securities in a manner adverse to the Holders, or

          (2) reduce the percentage in principal amount of the Outstanding

                                       59

the applicable Citigroup Trust shall have consented to such supplemental
indenture.

provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this

new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.

Section 10.1. Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities of such series and this Indenture, and will duly comply
with all other terms, agreements and conditions contained in, or made in the
Indenture for the benefit of, the Securities of such series.

Section 10.2. Maintenance of Office or Agency.

     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided that no such designation or rescission shall in any
manner relieve the Company of its obligation to maintain an office or agency in
each Place of Payment for Securities of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

Section 10.3. Money for Securities Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, prior to each due date of the principal of (and premium, if
any) or interest on any Securities of that series, deposit with a Paying Agent a
sum sufficient to

                                       61

<PAGE>

pay the principal (and premium, if any) or interest so becoming due, such sum to
be held in trust for the benefit of the Persons entitled to such principal,
premium or interest, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section, that such Paying Agent will:

          (1) hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest on Securities of that series in trust for the
     benefit of the Persons entitled thereto until such sums shall be paid to
     such Persons or otherwise disposed of as herein provided;

          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal (and premium, if any) or interest on the Securities of
     that series; and

          (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest on any Security of any series and remaining unclaimed for three
years after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in a newspaper published in the English
language, customarily published on each Business Day and of general circulation
in the Borough of Manhattan, The City of New York, New York, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

     If Securities of any series are to be issued as a Global Security in
connection with the distribution of such Securities to the holders of the
Preferred Securities of a Citigroup Trust upon a Dissolution Event with respect

                            REDEMPTION OF SECURITIES

Section 11.1. Applicability of Article; Federal Reserve Concurrence or Approval.

     Securities of each series are redeemable before their respective Stated
Maturities in accordance with their respective terms and (except as otherwise
specified as contemplated by Section 3.1 for Securities of any series) in
accordance with this Article. Any redemption of any series of Securities, in
whole or in part, prior to their respective Stated Maturities shall be subject
to receipt by the Company of the prior concurrence or approval of the Federal
Reserve or its staff, (i) if such concurrence or approval is then required in
order for securities such as the Securities to qualify as tier 1 capital under
applicable capital adequacy guidelines, regulations, policies, published
interpretations, or concurrence or approval of the Federal Reserve or its staff,
or (ii) if the Federal Reserve or its staff has informed the Company that it
must obtain such approval before redeeming the Securities.

Section 11.2. Election to Redeem; Notice to Trustee.

     (a) Subject to the provisions of Section 11.2(b) and to the other
provisions of this Article XI, except as otherwise may be specified in this
Indenture or, with respect to any series of Securities, as otherwise specified
as contemplated by Section 3.1 for the Securities of such series, the Company
shall have the right to redeem any series of Securities, in whole or in part,
from time to time, on or after the Redemption Option Date for such series at the
Redemption Price. The election of the Company to redeem any Securities
redeemable at the election of the Company shall be evidenced by a Board
Resolution. In case of any redemption at the election of the Company of less
than all the Securities of any series, the Company shall, at least 40 days
(unless a shorter period is acceptable to the Trustee), but not more than 60
days, prior to the Redemption Date fixed by the Company, notify the Trustee of
such Redemption Date and of the principal amount of Securities of such series to
be redeemed. In the case of any redemption of Securities prior to the expiration
of any restriction on such redemption provided in the terms of such Securities
or elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

     (b) If a partial redemption of any series of Securities would result in the
delisting of the Preferred Securities of the Citigroup Trust that purchased such
Securities from any national securities exchange or other organization on which
the Preferred Securities of such Citigroup Trust are then listed, the Company
shall not be permitted to effect such partial redemption and may only redeem
such series of Securities in whole.

Section 11.3. Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not

                                       65

<PAGE>

previously called for redemption, by such method as the Trustee shall deem fair
and appropriate and which may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series; provided, that, if at the time of redemption such
Securities are registered as a Global Security, the Depositary shall determine,
in accordance with its procedures, the principal amount of such Securities held
by each Security Beneficial Owner to be redeemed.

     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.

Section 11.4. Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

     All notices of redemption shall state:

          (1) the Redemption Date,

          (2) the Redemption Price,

          (3) if less than all the Outstanding Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Securities of such series to be
     redeemed,

          (4) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and that interest
     thereon will cease to accrue on and after said date, and

          (5) the place or places where such Securities are to be surrendered
     for payment of the Redemption Price.

     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

                                       66

Section 11.5. Deposit of Redemption Price.

     Prior to 10:00 a.m., New York City time, on any Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.3) an amount of money sufficient to pay the Redemption
Price of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Securities which are to be redeemed on that date.

Section 11.6. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided that installments of interest whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders
of such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 3.7.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate prescribed therefor in the
Security.

     The Redemption Price shall be paid prior to 12:00 noon, New York City time,
on the date of such redemption or such earlier time as the Company determines,
provided that the Company shall deposit with the Trustee an amount sufficient to
pay the Redemption Price by 10:00 a.m., New York City time, on the date such
Redemption Price is to be paid.

Section 11.7. Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment for Securities of that series (with, if the Company or the
Trustee so requires, due endorsement by, or a written instrument of transfer in
form satisfactory to the Company duly executed by, the Holder thereof or his
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series, of like tenor
and of any authorized denomination as requested by such Holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered.

Section 11.8. Tax Event Redemption.

     If a Tax Event with respect to any Citigroup Trust has occurred and is
continuing and:

     (a) the Company has received a Redemption Tax Opinion with respect to such
Citigroup Trust; or

     (b) after receiving a Tax Event Opinion, the Regular Trustees of such
Citigroup Trust shall have been informed by tax counsel rendering the Tax Event
Opinion that a No Recognition Opinion cannot be delivered to such Citigroup
Trust,

then, notwithstanding Section 11.2(a) but subject to Section 11.2(b) and Section
11.1, the Company shall have the right upon not less than 30 days nor more than
60 days notice to the Holders of Securities of the series issued to such
Citigroup Trust, or to its Institutional Trustee, to redeem such Securities, in
whole or in part, for cash within 90 days following the occurrence of such Tax
Event at the Redemption Price, provided that if at the time there is available
to the Company or such Citigroup Trust the opportunity to eliminate, within such
90-day period, the Tax Event by taking some ministerial action ("Ministerial
Action"), such as filing a form or making an election, or pursuing some other
similar reasonable measure which has no adverse effect on the Company, the Trust
or the holders of the Trust Securities of such Citigroup Trust, the Company or
such Citigroup Trust shall pursue such Ministerial Action in lieu of redemption,
and, provided further that the Company shall have no right to redeem such
Securities while the Company or such Citigroup Trust is pursuing any Ministerial
Action pursuant to its obligations under the Declaration of such Citigroup
Trust.

                                  ARTICLE XIII

                      EXTENSION OF INTEREST PAYMENT PERIOD

Section 13.1. Extension of Interest Payment Period.

     The Company shall have the right, at any time and from time to time during
the term of the Securities of any series, to defer payments of interest by
extending the interest payment period of all Securities of such series for a
period not exceeding 40 consecutive quarters (the "Extended Interest Payment
Period"), during which Extended Interest Payment Period no interest shall be due
and payable on Securities of such series; provided that no Extended Interest
Payment Period may extend beyond the Maturity of such Securities. To the extent
permitted by applicable law, interest, the payment of which has been deferred
because of the extension of the interest payment period pursuant to this Section
13.1, will bear interest thereon at the Coupon Rate compounded quarterly for
each quarter of the Extended Interest Payment Period ("Compounded Interest"). At

                                       68

<PAGE>

the end of any Extended Interest Payment Period with respect to any series of
Securities, the Company shall pay all interest accrued and unpaid on such
Securities, including any Additional Interest and Compounded Interest (together,
"Deferred Interest") that shall be payable to the Holders of Securities of such
Series in whose names such Securities are registered in the Security Register on
the first record date after the end of such Extended Interest Payment Period.
Before the termination of any Extended Interest Payment Period, the Company may
further extend such period; provided that such period, together with all such
further extensions thereof, shall not exceed 40 consecutive quarters; and
provided further that no prepayment of interest during an Extended Interest
Payment Period shall allow the Company to extend such Extended Interest Payment
Period beyond 40 consecutive quarters. Upon the termination of any Extended
Interest Payment Period with respect to any series of Securities and upon the
payment of all Deferred Interest then due, the Company may commence a new
Extended Interest Payment Period with respect to such series of Securities,
subject to the foregoing requirements. No interest on a series of Securities
shall be due and payable during an Extended Interest Payment Period with respect
thereto, except at the end thereof, provided the Company may prepay at any time
all or any portion of the interest accrued during any Extended Interest Payment
Period.

Section 13.2. Notice of Extension.

     (a) If the Institutional Trustee of a Citigroup Trust is the only Holder of
Securities of a series at the time the Company selects an Extended Interest
Payment Period with respect thereto, the Company shall give written notice to
the Regular Trustees and the Institutional Trustee of such Citigroup Trust and
to the Trustee of its selection of such Extended Interest Payment Period at
least one Business Day before the earlier of (i) the next succeeding date on
which Distributions on the Trust Securities issued by such Citigroup Trust are
payable, or (ii) the date such Citigroup Trust is required to give notice of the
record date, or the date such Distributions would be payable if not for such
Extended Interest Payment Period, to the New York Stock Exchange or other
applicable self-regulatory organization or to holders of the Preferred
Securities issued by such Citigroup Trust, but in any event at least one
Business Day before such record date.

     (b) If the Institutional Trustee of a Citigroup Trust is not the only
Holder of Securities of a series at the time the Company selects an Extended
Interest Payment Period with respect thereto, the Company shall give written
notice to the Holders of Securities of such series and the Trustee of its
selection of such Extended Interest Payment Period at least 10 Business Days
before the earlier of (i) the next succeeding Interest Payment Date, or (ii) the
date the Company is required to give notice of the record or payment date of
such interest payment to the New York Stock Exchange or other applicable
self-regulatory organization or to Holders of Securities of such series.

     (c) The quarter in which any notice is given pursuant to paragraphs (a) or
(b) of this Section 13.2 shall be counted as one of the 40 quarters permitted in
the maximum Extended Interest Payment Period with respect to any series of
Securities permitted under Section 1.3.

                                       69

<PAGE>

     (d) Notwithstanding anything else contained in this Indenture, the Company
shall be required to give notice to any person of its selection of an Extended
Interest Payment Period no more than 15 Business Days and no less than 5
Business Days before the next succeeding Interest Payment Date of the affected
Securities.

Section 13.3. Limitation of Transactions.

     If with respect to any series of Securities (i) the Company shall exercise
its right to defer payments of interest thereon as provided in Section 13.1 or
(ii) there shall have occurred any Default, then (a) the Company 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 Company 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 shares of common stock of Citigroup pursuant to
a contractually binding requirement to buy stock existing prior to the
commencement of the extension period, including under a contractually binding
stock repurchase plan (iii) as a result of an exchange or conversion of any
class or series of the Company's capital stock for any other class or series of
the Company's capital stock, (iv) the purchase of fractional interests in shares
of the Company'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 Citigroup's capital stock in connection with the distribution
thereof); and (b) except for any partial payments of Deferred Interest that may
be made pursuant to Section 13.5(d), the Company shall not make any payment of
interest on, principal of or premium, if any, on, or repay, repurchase or
redeem, any debt securities or guarantees issued by the Company that rank pari
passu with or junior to the Securities of such series (including the Securities
of any other series), provided, however, the Company may declare and pay a stock
dividend where the dividend stock is the same stock as that on which the
dividend is being paid. If any Extended Interest Payment Period lasts longer
than one year, unless required to do so by the Federal Reserve and subject to
the exceptions listed in clauses (a) and (b) of this Section 13.3, the Company
will not repurchase any of its common stock for a one-year period following the
payment of all Deferred Interest with the New Equity Amount.

Section 13.4. Limitation on Source of Payment of Deferred Interest.

     During an Extended Interest Payment Period, the Company may not pay
Deferred Interest on the Securities on any date in an amount that exceeds the
New Equity Amount for such date; provided, however, that (i) upon the Maturity
of the Securities, (ii) during the occurrence and continuation of a Supervisory
Event or (iii) if an Event of Default and Acceleration shall have occurred and
be continuing, the provisions of this Section 13.4 shall not apply and the
Company may pay Deferred Interest with cash from any source. Nothing in this
Indenture will prevent the Company from paying current interest on the
Securities at any time using cash from any source.

Section 13.5. Obligation to Effect Certain Common Stock Sales.

     (a) Commencing on the earlier of (i) the Fifth Deferral Anniversary, if on
such date the related Extended Interest Payment Period has not ended, and (ii)
the date of any payment of current interest on the Securities during an Extended
Interest Payment Period, if any Deferred Interest is outstanding, the Company
shall be subject to the "Alternative Payment Mechanism," pursuant to which it
will continuously use its commercially reasonable efforts to effect sales of
shares of its common stock, including treasury shares, in an amount that will
generate sufficient net proceeds to enable the Company to pay in full all
Deferred Interest on the Securities then outstanding; provided that the Company
shall not be obligated to make offers for or effect sales of its common stock
during the occurrence and continuation of a Market Disruption Event or a
Supervisory Event and will be permitted to pay Deferred Interest using cash from
any source upon the occurrence of a Supervisory Event. The Company's obligation
to use commercially reasonable efforts to sell shares of its common stock to pay
all Deferred Interest on the Securities shall resume at such time as no Market
Disruption Event or Supervisory Event exists or is continuing.

     (b) As used in this Section 13.5, the term "commercially reasonable
efforts" means commercially reasonable efforts on the part of the Company to
complete the sale of shares of its common stock, including treasury shares, to
third parties that are not subsidiaries of the Company. The Company will not be
considered to have used its commercially reasonable efforts to effect a sale of
stock if it determines not to pursue or complete such sale solely due to pricing
considerations.

     (c) The Company is not permitted to sell shares of common stock in excess
of a number of shares of common stock which at _______ __, 2006 is equal to
55,000,000 (the "Share Cap Amount"), for the purpose of satisfying Section
13.5(a) or otherwise paying Deferred Interest on the Securities then
outstanding. If the issued and outstanding shares of common stock shall have
been changed into a different number of shares or a different class by reason of
any stock split, reverse stock split, stock dividend, reclassification,
recapitalization, split-up, combination, exchange of shares or other similar
transaction, then the Share Cap Amount shall be correspondingly adjusted. The
Company shall increase the Share Cap Amount (including through the increase of
its authorized share capital, if necessary) to an amount that would allow the
Company to raise sufficient proceeds to satisfy its obligations to pay Deferred
Interest in full at the end of the first year of an Extended Interest Payment
Period (and on each subsequent anniversary of the end of the first year of an
Extended Interest Payment Period to the extent that an Extended Interest Payment
Period would last more than one year), if the then-current Share Cap Amount
would not allow the Company to raise sufficient proceeds to satisfy its
obligations to pay Deferred Interest (including Compounded Interest to that
date) assuming a price per share equal to the average trading price of the
Company's common shares over the ten-trading-day period preceding such date;
provided that the Company will not be obligated to increase the Share Cap Amount
above 165 million shares. Until the Tenth Deferral Anniversary, a Default will
occur if the Company does not increase the Share Cap Amount to an amount that is
greater than 55 million shares when required to do so as described above;
provided that no Default will occur if the Company has increased the share cap
amount to 165 million shares.

     (d) Following the earlier of (i) the Fifth Deferral Anniversary and (ii)
the date of any payment of current interest during an Extended Interest Payment
Period, the Company shall apply the net proceeds received by it from sales of
shares of its common stock, including sales of treasury shares, to the payment
of all amounts owing in respect of Deferred Interest, with net proceeds to be
paid promptly after receipt until all amounts owing in respect of Deferred
Interest have been paid in full. In the event that net proceeds received by the
Company from one or more sales of shares of its common stock following such
Fifth Deferral Anniversary are not sufficient to satisfy the full amount of
Deferred Interest, such net proceeds will be paid to the holders of the
Securities on a pro rata basis; provided, that if the Company has outstanding at
such time any debt securities ranking pari passu with the Securities under the
terms of which the Company is obligated to sell shares of its common stock and
apply the net proceeds to payment of deferred interest on such pari passu
securities and the Company at such time is required to apply such proceeds to
pay deferred interest on such pari passu securities, then on any date and for
any period the amount of net proceeds received by the Company from such sales
and available for payment of such deferred interest shall be applied to the
Securities and such pari passu securities on a pro rata basis. Notwithstanding
the above, the Company shall not be obligated to sell common stock or to apply
such net proceeds or any portion thereof to the payment of Deferred Interest
during the occurrence and continuation of Market Disruption Event or a
Supervisory Event.

     (e) Notwithstanding anything to the contrary in this Indenture, under no
circumstances will the Company be obligated to sell shares of Qualified Warrants
or to apply the proceeds of any such sale to pay Deferred Interest on the
Securities.

     (f) Notwithstanding anything to the contrary in this Indenture, the Company
will not be obligated to issue common stock prior to the Fifth Deferral
Anniversary if the gross proceeds of any issuance of common stock and Qualified
Warrants applied to pay Deferred Interest on the Securities pursuant to this
Section 13.5, together with the gross proceeds of all prior issuances of common
stock and Qualified Warrants applied since the commencement of the Extended
Interest Payment Period, would exceed an amount equal to 2% of the product of
(1) the average of the Current Stock Market Prices of the Company's common stock
on the 10 consecutive trading days ending on the fourth trading day immediately
preceding the date of issuance by the Company of common stock applied to pay
Deferred Interest on the Securities pursuant to Section 13.5 and (2) the total
number of issued and outstanding shares of the Company's common stock as of the
date of the Company's publicly available consolidated financial statements (the
"APM Maximum Obligation"). Once the Company reaches the APM Maximum Obligation
for an Extended Interest Payment Period, the Company will not be obligated to
issue more common stock or Qualified Warrants pursuant to this Section 13.5
prior to the Fifth Deferral Anniversary even if the Current Stock Market Price
of the Company's common stock or the number of outstanding shares of its common
stock subsequently increase. The APM Maximum Obligation will cease to apply
following the Fifth Deferral Anniversary, at which point the Company must repay
any Deferred Interest, regardless of the time at which it was deferred, using
proceeds from sales of the Company's common stock, including treasury shares,
subject to any Market Disruption Event, Supervisory Event, and the Share Cap
Amount. If the APM Maximum Obligation has been reached

                                       72

<PAGE>

during an Extended Interest Payment Period and the Company subsequently repays
all Deferred Interest, the APM Maximum Obligation will cease to apply at the
termination of such Extended Interest Payment Period and will not apply again
unless and until the Company starts a new Extended Interest Payment Period.

Section 13.6. Notice of Market Disruption Event.

     Upon and after the Fifth Deferral Anniversary, if a Market Disruption Event
has occurred and is continuing, the Company shall give, as promptly as possible
after the Company becomes aware of such occurrence, a written notice (a "Market
Disruption Event Notice") to the Trustee, stating the date on which such Market
Disruption Event has occurred, the nature thereof and what action it will take
in connection therewith.

Section 13.7. Notice of Supervisory Event.

     Upon and after the Fifth Deferral Anniversary, if a Supervisory Event has
occurred and is continuing, the Company shall give, as promptly as possible
after the Company becomes aware of such occurrence, a written notice (a
"Supervisory Event Notice") to the Trustee stating that a Supervisory Event has
commenced and the actions it will take in connection therewith. No later than
five (5) Business Days following termination of a Supervisory Event, the Company
shall give a written notice to the Trustee stating the date on which such
Supervisory Event terminated.

Section 13.8. Notices to the Federal Reserve.

     The Company shall give written notice to the Federal Reserve:

     (a) No later than five (5) Business Days following commencement of an
Extended Interest Payment Period; and

     (b) Upon the earlier to occur of (i) the Fifth Deferral Anniversary of such
Extended Interest Payment Period or (ii) the payment of current interest during
an Extended Interest Payment Period.

Section 13.9. Obligation to Notify Federal Reserve of Intent to Sell Stock.

     (a) At least 25 Business Days in advance of the relevant payment date (or
such longer period as may be required by the Federal Reserve or by other
supervisory action) the Company shall give written notice to the Federal Reserve
of its intent both (1) to sell shares of common stock or, at the Company's sole
discretion, Qualified Warrants and (2) to apply the net proceeds from such sale
to pay Deferred Interest, and shall only take any such actions if the Federal
Reserve does not disapprove of any such actions within ten (10) Business Days
after the Company gives such notice to the Federal Reserve or has withdrawn any
prior disapproval.

                                   ARTICLE XIV

                           SUBORDINATION OF SECURITIES

Section 14.1. Agreement to Subordinate.

     The Company covenants and agrees, and each Holder of Securities issued
hereunder by such Holder's acceptance thereof likewise covenants and agrees,
that all Securities shall be issued subject to the provisions of this Article
Fourteen; and each Holder of a Security, whether upon original issue or upon
transfer or assignment thereof, accepts and agrees to be bound by such
provisions.

     The payment by the Company of the principal of, premium, if any, and
interest on all Securities issued hereunder shall, to the extent and in the
manner hereinafter set forth, be subordinated and junior in right of payment to
the prior payment in full of all Senior Indebtedness of the Company, whether
outstanding at the date of this Indenture or thereafter incurred.

     No provision of this Article Fourteen shall prevent the occurrence of any
Default hereunder.

Section 14.2. Default on Senior Indebtedness.

     In the event and during the continuation of any default by the Company in
the payment of principal, premium, interest or any other payment due on any
Senior Indebtedness of the Company, as the case may be, or in the event that the
maturity of any Senior Indebtedness of the Company, as the case may be, has been
accelerated because of a default, then, in either case, no payment shall be made
by the Company with respect to the principal (including redemption payments) of,
or premium, if any, or interest on, the Securities or to acquire any of the
Securities.

     In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee, by any Holder or by any Paying Agent (or, if the
Company is acting as its own Paying Agent, money for any such payment is
segregated and held in trust) when such payment is prohibited by the preceding
paragraph of this Section 14.2, before all Senior Indebtedness of the Company is
paid in full, or provision is made for such payment in money in accordance with
its terms, such payment shall be held in trust for the benefit of, and shall be
paid over or delivered to, the holders of Senior Indebtedness of the Company or
their respective representatives, or to the trustee or trustees under any
indenture pursuant to which any of such Senior Indebtedness may have been
issued, as their respective interests may appear, ratably according to the
aggregate amount remaining unpaid on account of the principal, premium, interest
or any other payment due on the Senior Indebtedness held or represented by each,
for application to the payment of all Senior Indebtedness of the Company, as the
case may be, remaining unpaid to the extent necessary to pay such Senior
Indebtedness in full in money in accordance with its terms, after giving effect
to any concurrent payment or distribution to or for the benefit of the holders
of such Senior Indebtedness, but only to the extent that

                                       74

<PAGE>

the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

Section 14.3. Liquidation; Dissolution; Bankruptcy.

     Upon any payment by the Company or distribution of assets of the Company of
any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding-up or liquidation or reorganization of the
Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due upon all Senior Indebtedness
of the Company shall first be paid in full, or payment thereof provided for in
money in accordance with its terms, before any payment is made by the Company on
account of the principal (and premium, if any) or interest on the Securities;
and upon any such dissolution or winding-up or liquidation or reorganization,
any payment by the Company, or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the Holders of
the Securities or the Trustee would be entitled to receive, except for the
provisions of this Article Fourteen, shall be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the Holders of the Securities or by
the Trustee under this Indenture if received by them or it, directly to the
holders of Senior Indebtedness of the Company (pro rata to such holders on the
basis of the respective amounts of Senior Indebtedness held by such holders, as
calculated by the Company) or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing such Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay such Senior Indebtedness in
full, in money or money's worth, after giving effect to any concurrent payment
or distribution to or for the holders of such Senior Indebtedness, before any
payment or distribution is made to the Holders of Securities or to the Trustee.

     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee, by any Holder or by any Paying Agent (or, if the Company is acting as
its own Paying Agent, money for any such payment is segregated and held in
trust) before all Senior Indebtedness of the Company is paid in full, or
provision is made for such payment in money in accordance with its terms, such
payment or distribution shall be held in trust for the benefit of and shall be
paid over or delivered to the holders of such Senior Indebtedness or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any of such Senior Indebtedness may have been
issued, as their respective interests may appear, ratably according to the
aggregate amount remaining unpaid on account of the principal, premium, interest
or any other payment due on the Senior Indebtedness held or represented by each,
as calculated by the Company, for application to the payment of all Senior
Indebtedness of the Company, as the case may be, remaining unpaid to the extent
necessary to pay such Senior Indebtedness in full in money in accordance with
its terms,

                                       75

<PAGE>

after giving effect to any concurrent payment or distribution to or for the
benefit of the holders of such Senior Indebtedness.

     For purposes of this Article Fourteen, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Fourteen with
respect to the Securities to the payment of all Senior Indebtedness of the
Company, as the case may be, that may at the time be outstanding, provided that
(i) such Senior Indebtedness is assumed by the new corporation, if any,
resulting from any such reorganization or readjustment, and (ii) the rights of
the holders of such Senior Indebtedness are not, without the consent of such
holders, altered by such reorganization or readjustment. The consolidation of
the Company with, or the merger of the Company into, another corporation or the
liquidation or dissolution of the Company following the conveyance or transfer
of its property as an entirety, or substantially as an entirety, to another
corporation upon the terms and conditions provided for in Article VIII shall not
be deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this Section 14.3 if such other corporation shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions stated
in Article VIII. Nothing in Section 14.2 or in this Section 14.3 shall apply
to-claims of, or payments to the Trustee under or pursuant to Section 6.7.

Section 14.4. Subrogation.

     Subject to the payment in full of all Senior Indebtedness of the Company,
the rights of the Holders of the Securities shall be subrogated to the rights of
the holders of such indebtedness to receive payments or distributions of cash,
property or securities of the Company, as the case may be, applicable to such
Senior Indebtedness until the principal of (and premium, if any) and interest on
the Securities shall be paid in full; and, for the purposes of such subrogation,
no payments or distributions to the holders of such Senior Indebtedness of any
cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article Fourteen,
and no payment over pursuant to the provisions of this Article Fourteen to or
for the benefit of the holders of such Senior Indebtedness by Holders of the
Securities or the Trustee, shall, as between the Company, its creditors other
than Holders of Senior Indebtedness of the Company, and the holders of the
Securities, be deemed to be a payment by the Company to or on account of such
Senior Indebtedness. It is understood that the provisions of this Article
Fourteen are and are intended solely for the purposes of defining the relative
rights of the Holders of the Securities, on the one hand, and the holders of
such Senior Indebtedness on the other hand.

     Nothing contained in this Article Fourteen or elsewhere in this Indenture
or in the Securities is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Indebtedness of the Company, and the
Holders of the Securities, the obligation of the Company, which is absolute and
unconditional, to pay to the Holders of the Securities the principal of (and
premium, if any) and interest on the Securities as and when the same shall
become due and payable in accordance with their terms, or is

                                       76

<PAGE>

intended to or shall affect the relative rights of the Holders of the Securities
and creditors of the Company, as the case may be, other than the holders of
Senior Indebtedness of the Company, as the case may be, nor shall anything
herein or therein prevent the Trustee or the Holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under
the Indenture, subject to the rights, if any, under this Article Fourteen of the
holders of such Senior Indebtedness in respect of cash, property or securities
of the Company, as the case may be, received upon the exercise of any such
remedy.

     Upon any payment or distribution of assets of the Company referred to in
this Article Fourteen, the Trustee, subject to the provisions of Section 6.1,
and the Holders of the Securities shall be entitled to conclusively rely upon
any order or decree made by any court of competent jurisdiction in which such
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidation trustee,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of the Securities, for the purposes of ascertaining
the Persons entitled to participate in such distribution, the holders of Senior
Indebtedness and other indebtedness of the Company, as the case may be, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article Fourteen.

Section 14.5. Trustee to Effectuate Subordination.

     Each Holder of Securities by such Holder's acceptance thereof authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article Fourteen and appoints the Trustee such Holder's attorney-in-fact for any
and all such purposes.

Section 14.6. Notice by the Company.

     The Company shall give prompt written notice to a Responsible Officer of
the Trustee of any fact known to the Company that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article Fourteen. Notwithstanding the provisions of
this Article Fourteen or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts that would
prohibit the making of any payment of monies to or by the Trustee in respect of
the Securities pursuant to the provisions of this Article Fourteen, unless and
until a Responsible Officer of the Trustee shall have received written notice
thereof from the Company or a holder or holders of Senior Indebtedness or their
representative or representatives or from any trustee therefor; and before the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 6.1 shall be entitled in all respects to assume that no such facts
exist; provided, however, that if the Trustee shall not have received the notice
provided for in this Section 14.6 at least three Business Days prior to the date
upon which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of (or premium, if
any) or interest on any Security), then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority

                                       77

<PAGE>

to receive such money and to apply the same to the purposes for which they were
received, and shall not be affected by any notice to the contrary that may be
received by it within three Business Days prior to such date.

     The Trustee, subject to the provisions of Section 6.1, shall be entitled to
conclusively rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness of the Company, as
the case may be (or a trustee on behalf of such holder), to establish that such
notice has been given by a holder of such Senior Indebtedness or a trustee on
behalf of any such holder or holders. In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of any
Person as a holder of such Senior Indebtedness to participate in any payment or
distribution pursuant to this Article Fourteen, the Trustee may request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of such Senior Indebtedness held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and any
other facts pertinent to the rights of such Person under this Article Fourteen,
and, if such evidence is not furnished, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment.

Section 14.7. Rights of the Trustee; Holders of Senior Indebtedness.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article Fourteen in respect of any Senior Indebtedness at any
time held by it, to the same extent as any other holder of Senior Indebtedness,
and nothing in this Indenture shall deprive the Trustee of any of its rights as
such holder.

     With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article Fourteen, and no
implied covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders of such Senior
Indebtedness and, subject to the provisions of Section 6.1, the Trustee shall
not be liable to any holder of such Senior Indebtedness if it shall pay over or
deliver to Holders of Securities, the Company or any other Person money or
assets to which any holder of such Senior Indebtedness shall be entitled by
virtue of this Article Fourteen or otherwise.

Section 14.8. Subordination May Not Be Impaired.

     No right of any present or future holder of any Senior Indebtedness of the
Company to enforce subordination as herein provided shall at any time in any way
be prejudiced or impaired by any act or failure to act on the part of the
Company, as the case may be, or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Company, as the case may be,
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof that any such holder may have or otherwise be charged with.

                                       78

<PAGE>

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness of the Company may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article
Fourteen or the obligations hereunder of the Holders of the Securities to the
holders of such Senior Indebtedness, do any one or more of the following: (i)
change the manner, place or terms of payment or extend the time of payment of,
or renew or alter, such Senior Indebtedness, or otherwise amend or supplement in
any manner such Senior Indebtedness or any instrument evidencing the same or any
agreement under which such Senior Indebtedness is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Senior Indebtedness; (iii) release any Person liable in
any manner for the collection of such Senior Indebtedness; and (iv) exercise or
refrain from exercising any rights against the Company, as the case may be, and
any other Person.

Section 14.9. Trustee's Compensation Not Prejudiced.

     Nothing in this Article Fourteen shall apply to amounts due to the Trustee
pursuant to Section 6.7 of this Indenture.

Section 14.10. Disclaimer of Right to Enforce Covenants.

     Except as specifically provided for in this Article 14, no holder of Senior
Indebtedness shall have any right to enforce any of the covenants in this
Indenture, including but not limited to those contained in Sections 5.11, 13.4,
13.5, 13.6, 13.7 and 13.8

                                   ARTICLE XV

                                  MISCELLANEOUS

Section 15.1. Acknowledgement of Rights.

     The Company acknowledges that, with respect to any Securities held by a
Citigroup Trust or a trustee of such Trust, if the Institutional Trustee of such
Citigroup Trust fails to enforce its rights under this Indenture as the Holder
of the series of Securities held as the assets of such Citigroup Trust, any
holder of Preferred Securities of such Citigroup Trust may institute legal
proceedings directly against the Company to enforce such Institutional Trustee's
rights under this Indenture without first instituting any legal proceedings
against such Institutional Trustee or any other person or entity.

     Notwithstanding the foregoing, if a Default has occurred and is continuing
and such event is attributable to the failure of the Company to pay interest or
principal on the applicable series of Securities on the date such interest or
principal is otherwise payable (or in the case of redemption, on the redemption
date), the Company acknowledges that a holder of Trust Securities issued by the
Citigroup Trust which is, or the Institutional Trustee of which is, the Holder
of such Securities may directly institute a proceeding for

                                       79

<PAGE>

enforcement of payment to such holder of the principal of or interest on the
applicable series of Securities having a principal amount equal to the aggregate
liquidation amount of the Trust Securities of such holder (a "Direct Action") on
or after the respective due date specified of such holder on or after the
respective due date specified in the applicable series of Securities.
Notwithstanding any payments made to such holder of Trust Securities by the
Company in connection with a Direct Action, the Company shall remain obligated
to pay the principal of or interest on the series of Securities held by a
Citigroup Trust or the Institutional Trustee of a Citigroup Trust, and the
Company shall be subrogated to the rights of the holder of such Trust Securities
to the extent of any payments made by the Company to such holder in any Direct
Action.

Section 15.2. Severability.

     In case any provision in this Indenture or in any series of Securities
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

Section 15.3. Counterparts.

     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.
