(ii) unsecured junior subordinated debt securities (the "Junior Subordinated
Debt Securities") of the Company, which are to be issued pursuant to an
Indenture, dated as of October 7, 1996, as supplemented by the First
Supplemental Indenture thereto dated as of December 15, 1998 (as so
supplemented, the "Indenture"), between the Company and JPMorgan Chase Bank
(formerly The Chase Manhattan Bank), as debt trustee (the "Debt Trustee"), (iii)
shares of preferred stock, par value $1.00 per share (the "Preferred Stock"), of
the Company to be issued in one or more series, which may also be issued in the
form of depositary shares (the "Depositary Shares") evidenced by depositary
receipts (the "Receipts") pursuant to one or more deposit agreements (each, a
"Deposit Agreement") to be entered into between the Company and a depositary to
be named (the "Depositary"), (iv) stock purchase contracts (the "Stock Purchase
Contracts") to purchase Common Stock (as defined below), Preferred Stock or

Chase Manhattan Bank Delaware), as Delaware trustee (the "Delaware Trustee"),
JPMorgan Chase Bank, as property trustee (the "Property Trustee"), and William

601(b)(5) of Regulation S-K under the Act. Capitalized terms used but not
otherwise defined herein have the meanings ascribed to them in the Registration
Statement.

     In connection with this opinion, we have examined originals or copies,

(C) Citigroup Capital XI, as filed with the Secretary of State of the State of
Delaware on December 7, 1998, (D) Citigroup Capital XII, as filed with the
Secretary of State of the State of Delaware on December 7, 1998 and (E)
Citigroup Capital XIII, as filed with the Secretary of State of the State of
Delaware on December 7, 1998 (collectively, the "Certificates of Trust"); (iii)

of the designations of the terms of the Capital Securities of such Citigroup
Trust annexed thereto); (iv) the form of the Capital Securities of each of the
Citigroup Trusts; (v) the form of the capital securities guarantee agreement
(the "Capital Securities Guarantee"), to be entered into by the Company and
JPMorgan Chase Bank, as guarantee trustee (the "Capital Securities Guarantee

drafts of certain resolutions of the Board of Directors of the Company (the
"Draft Resolutions") relating to the issuance and sale of the Offered Debt
Securities (as defined below), the Capital Securities Guarantee, the Preferred
Stock, the Depositary Shares, the Stock Purchase Contracts, the Stock Purchase
Units and the Offered Common Stock and related matters and (xii) a specimen
certificate evidencing the Common Stock. We have also examined originals or
copies, certified or otherwise identified to our satisfaction, of such other
documents, certificates and records as we have deemed necessary or appropriate
as a basis for the opinions set forth herein.


     In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such copies. In making our examination of
executed documents or documents to be executed, we have assumed that the parties
thereto, other than the Company and the Citigroup Trusts, had or will have the
power, corporate, trust or other, to enter into and perform all obligations
thereunder and have also assumed the due authorization by all requisite action,
corporate or other, and execution and delivery by such parties of such documents
and that such documents constitute valid and binding obligations of such
parties. In addition, we have assumed that the Declaration of each Citigroup
Trust, the Capital Securities of each Citigroup Trust, the Capital Securities
Guarantee and the Junior Subordinated Debt Securities will be executed in
substantially the form reviewed by us and that the terms of the Offered Capital
Securities (as defined below), the Offered Debt Securities (as defined below),
the Offered Preferred Stock (as defined below), the Depositary Shares, the
Offered Stock Purchase Contracts (as defined below) and the Offered Stock
Purchase Units (as defined below) will have been established so as not to
violate, conflict with or constitute a default under (i) any agreement or
instrument to which the Company or any of the Citigroup Trusts or their
respective property is subject, (ii) any law, rule, or regulation to which the
Company or

administrative order or decree of any governmental authority or (iv) any
consent, approval, license, authorization or validation of, or filing, recording
or registration with any governmental authority. We have also assumed that (i)
the stock certificates evidencing the Preferred Stock to be issued will be in a
form that complies with, and the terms of such Preferred Stock will be duly
established in accordance with, the Delaware General Corporation Law (the
"DGCL"), and (ii) the stock certificate evidencing any Offered Common Stock
issued will conform to the specimen certificate examined by us and will be duly
executed and delivered. As to any facts material to the opinions expressed
herein which were not independently established or verified, we have relied upon
oral or written statements and representations of officers, trustees and other
representatives of the Company, the Citigroup Trusts and others.

     We do not express any opinion as to any laws other than Delaware corporate
law and the laws of the State of New York. Insofar as the opinions expressed
herein relate to matters governed by laws other than those set forth in the
preceding sentence, we have assumed, without having made any independent
investigation, that such laws do not affect any of the opinions set forth
herein. The opinions expressed herein are based on laws in effect on the date
hereof, which laws are subject to change with possible retroactive effect.

     Based on and subject to the foregoing and to the other qualifications and
limitations set forth herein, we are of the opinion that:

     Company; (iii) the filing of such certificate of designation with the
     Secretary of State of the State of Delaware has duly occurred; (iv) if the

     Common Stock upon conversion of the Offered Preferred Stock, the
     Certificate of Incorporation, the By-Laws and the DGCL shall not have been

     binding purchase or agency agreement, will be valid and binding obligations
     of the Company, enforceable against the Company in accordance with their
     respective terms, except to the extent that enforcement thereof may be
     limited by (i) bankruptcy, insolvency, fraudulent conveyance,
     reorganization, moratorium, or other similar laws now or hereafter in
     effect relating to creditors' rights generally and (ii) general principles
     of equity (regardless of whether enforceability is considered in a
     proceeding at law or in equity).

     There is no provision in the Certificate of Incorporation which purports to
restrict the surplus of the Company by reason of the excess, if any, of the
liquidation preference of the shares of Preferred Stock over their par value.
The applicable provisions of the DGCL, 8 Del. C. Sections 154 and 170(a), which
define capital and surplus of a Delaware corporation available for the payment
of dividends, do not purport to restrict such surplus by reason of any such
excess. Moreover, we are not aware of any applicable provisions of the
Constitution of the State of Delaware nor any controlling Delaware case law
which would suggest that surplus would be restricted by the excess of the
liquidation preference over the par value of the shares of Preferred Stock.
Accordingly, while there are no authorities specifically addressing this issue,
it is our opinion that (i) there should be no restriction upon the surplus of
the Company available for the payment of dividends on any outstanding capital
stock of the Company solely by reason of the fact that the liquidation
preference of any shares of any series of Preferred Stock exceeds the par value
of such shares and (ii) no remedy should be available to the holders of any
shares of any series of Preferred Stock before or after payment of any dividend
solely because such dividend would reduce the surplus of the Company to an
amount less than the amount of such excess, assuming that the payment of such
dividend is in accordance with the provisions of the DGCL, and of the
Certificate of Incorporation including the applicable certificate of
designation.
