The Bear Stearns Companies Inc.
245 Park Avenue
New York, NY 10167

Ladies and Gentlemen:

     We have acted as special  counsel for The Bear  Stearns  Companies  Inc., a
Delaware corporation (the "Company"),  in connection with the preparation of the
Company's  Registration  Statement  on Form S-3 (the  "Registration  Statement")
pursuant to the Securities Act of 1933, as amended (the "Securities Act"), being
filed with the Securities and Exchange Commission (the "Commission") on the date
hereof  and to  which  this  opinion  letter  is an  exhibit.  The  Registration
Statement  relates  to an  indeterminate  aggregate  principal  amount of Junior
Subordinated  Deferrable  Interest Debentures (the "Debentures") of the Company,
an  indeterminate  aggregate  liquidation  amount of Preferred  Securities  (the
"Preferred  Securities")  of Bear Stearns Capital Trust II, Bear Stearns Capital
Trust III, Bear Stearns  Capital Trust IV and Bear Stearns Capital Trust V, each
a Delaware business trust  (collectively,  the "Trusts"),  the guarantees by the
Company (the  "Guarantees")  of the Preferred  Securities  and an  indeterminate
number of shares of the  Company's  Preferred  Stock,  par value $1.00 per share
(the "Preferred Stock"),  as may be issued from time to time,  collectively with
an aggregate  offering price of  $750,000,000.  The Debentures and the Preferred
Stock will be, and the Guarantees will relate to Preferred  Securities that will
be,  issued in one or more  series,  the terms of which  shall be fixed prior to
issuance by the Company and the applicable Trust.

     In rendering  the opinions  expressed  below,  we have  examined and relied
upon,  among  other  things,  (a)  the  Registration  Statement,  including  the
Prospectus  constituting  a  part  thereof,  (b)  the  form  of  indenture  (the
"Indenture"),  to be entered  into  between the Company and The Chase  Manhattan
Bank, as trustee, and the form of supplemental  indenture under which each issue
of Debentures will be made filed as exhibits to the Registration Statement,  (c)
the form of Preferred  Securities Guarantee Agreement under which the Guarantees
will be made filed as an exhibit to the Registration Statement and (d) originals
or copies,  certified  or  otherwise  identified  to our  satisfaction,  of such
certificates, corporate, public or other records, and other documents as we have
deemed  appropriate  for the  purpose  of  rendering  this  opinion  letter.  In
connection  with  such  examination,  we have  assumed  the  genuineness  of all
signatures,  the authenticity of all documents submitted to us as originals, the
conformity  to  original   documents  and   instruments  of  all  documents  and
instruments submitted to us as copies or specimens,  and the authenticity of the
originals  of such  documents  and  instruments  submitted  to us as  copies  or
specimens.  We have  also  made  such  investigations  of law as we have  deemed
appropriate. In addition, we have assumed that the Debentures and the

Guarantees  will be executed and  delivered in  substantially  the form in which
they are filed as exhibits to the Registration Statement.

     We are members of the Bar of the State of New York,  and in  rendering  the
opinions  below,  we do not  purport to be an expert in, or express  any opinion
concerning,  the laws of any jurisdiction other than the substantive laws of the
State of New York,  the General  Corporation  Law of the State of Delaware  and,
where expressly  referred to below,  the substantive  federal laws of the United
States of America (in each case without regard to conflicts of law principles).

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

     1. The Debentures and the Guarantees will be legally and validly issued and
binding  obligations of the Company (except to the extent  enforceability may be
limited  by  applicable  bankruptcy,  insolvency,  reorganization,   moratorium,
fraudulent   transfer  or  other  similar  laws  affecting  the  enforcement  of
creditors'  rights generally and by the effect of general  principles of equity,
regardless of whether  enforceability is considered in a proceeding in equity or
at law), when (a) the Registration  Statement,  as finally  amended,  shall have
become  effective  under the  Securities  Act and the Indenture  shall have been
qualified  under  the  Trust  Indenture  Act of 1939,  as  amended,  and (b) the
Debentures shall have been duly executed,  authenticated and delivered,  and the
Guarantees  shall have been duly executed and delivered,  as contemplated in the
Prospectus and applicable Prospectus Supplement.

     2. The  Company  has been duly  incorporated  and is validly  existing as a
corporation under the laws of the State of Delaware.

     3. The shares of  Preferred  Stock will be validly  issued,  fully paid and
non-assessable when (a) the Registration  Statement,  as finally amended,  shall
have become effective under the Securities Act and (b) the Preferred Stock shall
have been issued,  paid for and delivered as  contemplated in the Prospectus and
applicable  Prospectus  Supplement;  provided  that the  issuance  of  shares of
Preferred  Stock is duly authorized by the Company's Board of Directors and that
the number of shares of  Preferred  Stock  issued at no time exceeds the maximum
number of shares of Preferred  Stock  authorized  to be issued by the  Company's
Certificate of Incorporation.

     We hereby consent to the filing of this opinion letter as an exhibit to the
Registration  Statement  and to the  reference  to this  Firm in the  Prospectus

Matters,"  without  admitting  that we are  "experts"  within the meaning of the
Securities Act or the rules and regulations of the Commission  issued thereunder
with respect to any part of the Registration Statement, including this exhibit.
