Certificate of Incorporation of the Company, as amended to date (the
"Certificate of Incorporation"); (x) the By-Laws of the Company, as currently in
effect (the "By-Laws"); (xi) drafts of certain resolutions of the Board of
Directors of the Company (the "Draft Resolutions") relating to the

identified to our satisfaction, of such other documents, certificates and

     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 (defined below), the Offered Debt Securities (defined

will have been established so as not to violate, conflict with or constitute a
default under (i) any agreement or instrument to

Citigroup Trusts is subject, (iii) any judicial or administrative order or
decree of any governmental authority or (iv) any consent, approval, license,

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.

and New York, and we do not express any opinion as to the laws of any other

         however, that the holders of the Offered Capital Securities may be
         obligated, pursuant to the Declaration of such Citigroup Trust, to (i)
         provide indemnity and/or security in connection with, and pay taxes or
         governmental charges arising from, transfers of Offered Capital

         delivered by the applicable Citigroup Trust and the other parties
         thereto, the Capital Securities Guarantee, when duly executed and

         including the Certificate of Designation relating to the Offered
         Preferred Stock, and the By-Laws of the Company; (v) the filing of the
         Certificate of Designation with the Secretary of State of the State of
         Delaware has duly occurred; (vi) if the Offered Preferred Stock is to
         be sold pursuant to a firm commitment underwritten offering, the
         underwriting agreement with respect to the shares of the Offered
         Preferred Stock has been duly authorized, executed and delivered by the
         Company and the other parties thereto; and (vii) certificates

         thereof; and (2) if the Offered Preferred Stock is convertible into
         Offered Common Stock, the Offered Common Stock issuable upon conversion

         Common Stock upon conversion of the Offered Preferred Stock has been
         authorized by all necessary corporate action, that the Offered
         Preferred Stock has been converted in accordance with the terms of the
         Certificate of Designation and that the certificates evidencing such
         shares of Offered Common Stock are duly executed and delivered. In
         rendering the opinion set forth in clause (2) of this paragraph 4, we
         have assumed that, at the time of issuance of any Offered Common Stock
         upon conversion of the Offered Preferred Stock, the Certificate of
         Incorporation, the By-Laws and the DGCL shall not have been amended so
         as to affect the validity of such issuance.

         general principles of equity (regardless of whether enforcement 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.

         We hereby consent to the filing of this opinion with the Commission as
an exhibit to the Registration Statement. We also hereby consent to the use of
our name under the heading "Legal Matters" in each of the two prospectuses which
forms a part of the Registration Statement. In giving this consent, we do not
thereby admit that we are within the category of persons whose consent is
