The Goldman Sachs Group, Inc.,
         85 Broad Street,
                  New York, New York 10004.

Ladies and Gentlemen:

                  In connection with the registration under the Securities Act
of 1933 (the "Act") by The Goldman Sachs Group, Inc., a Delaware corporation
(the "Company"), of $16,815,000,000 aggregate amount of its senior and
subordinated debt securities, warrants, purchase contracts, units comprised of
the foregoing, preferred stock and depositary shares representing preferred
stock (collectively, the "Securities"), the shares of Common Stock, par value
$0.01 per share, of the Company (the "Shares") initially issuable upon
conversion, exercise or exchange of any Securities that are convertible into or
exercisable or exchangeable for Shares and the stock purchase rights related to
the Shares (the "Rights") to be issued pursuant to the Stockholder Protection
Rights Agreement, dated as of April 5, 1999, between the Company and Mellon
Investor Services LLC (successor to ChaseMellon Shareholder Services, L.L.C.),
as Rights Agent (the "Rights Agent"), we, as your counsel, have examined such
corporate records, certificates and other documents, including the resolutions
of the Company's Board of Directors authorizing the issuance of the Securities
(the "Resolutions"), and such questions of law, as we have considered necessary
or appropriate for the purposes of this opinion.

                  Upon the basis of such examination, we advise you that, in our
opinion:

                           (1) Indenture Securities. The indenture relating to
                  the senior debt securities, which is dated as of May 19, 1999,
                  has been duly authorized, executed and delivered by the
                  Company, and the indenture relating to the subordinated debt
                  securities and the indenture relating to certain of the
                  warrants, in the forms filed as exhibits to the registration
                  statement relating to the Securities, the Shares and the
                  Rights (the "Registration Statement"), have been duly
                  authorized by the Company. When the Registration Statement has
                  become effective under the Act, when the indenture relating to
                  the subordinated debt securities


The Goldman Sachs Group, Inc.                                                -2-


                  and the indenture relating to certain of the warrants have
                  been duly executed and delivered substantially in the forms so
                  filed, when the terms of the debt securities and the warrants
                  to be issued under the three indentures described above (the
                  "Indenture Securities") and of their issuance and sale have
                  been duly established in conformity with the applicable
                  indenture so as not to violate any applicable law or result in
                  a default under or breach of any agreement or instrument
                  binding upon the Company and so as to comply with any
                  requirement or restriction imposed by any court or
                  governmental body having jurisdiction over the Company and
                  when the Indenture Securities have been duly executed and
                  authenticated in accordance with the applicable indenture and
                  issued and sold as contemplated in the Registration Statement,
                  and if all the foregoing actions are taken pursuant to the
                  authority granted in the Resolutions, the Indenture Securities
                  will constitute valid and legally binding obligations of the
                  Company, subject to bankruptcy, insolvency, fraudulent
                  transfer, reorganization, moratorium and similar laws of
                  general applicability relating to or affecting creditors'
                  rights and to general equity principles, and the Shares, when
                  duly issued upon conversion, exercise or exchange of any
                  Indenture Securities that are convertible into or exercisable
                  or exchangeable for Shares, will be validly issued, fully paid
                  and nonassessable. The debt securities covered by the opinion
                  in this paragraph include any debt securities that may be
                  issued as part of the units or upon exercise or otherwise
                  pursuant to the terms of any other Securities, as well as any
                  purchase contracts or units that may be issued under the
                  indentures relating to the debt securities. The warrants
                  covered by the opinion in this paragraph include any warrants
                  issued under an indenture that may be issued as part of the
                  units or upon exercise or otherwise pursuant to the terms of
                  any other Securities.

                           (2) Warrants Not Issued Under an Indenture. When the
                  Registration Statement has become effective under the Act,
                  when the terms of the warrant agreements under which certain
                  of the warrants are to be issued have been duly established
                  and the warrant agreements have been duly executed and
                  delivered, when the terms of such warrants and of their
                  issuance and sale have been duly established in conformity
                  with the applicable warrant agreement and when such warrants
                  have been duly executed and authenticated in accordance with
                  the applicable warrant agreement and issued and sold as
                  contemplated in the Registration Statement, and if all the
                  foregoing actions are taken pursuant to the authority granted
                  in the Resolutions and so as not to violate any applicable law
                  or result in a default under or breach of any agreement or
                  instrument binding upon the Company and so as to comply with
                  any requirement or restriction imposed by any court or
                  governmental body having jurisdiction over the Company, such
                  warrants will constitute valid and legally binding obligations
                  of the Company, subject to bankruptcy, insolvency, fraudulent
                  transfer, reorganization, moratorium and similar laws of
                  general applicability relating to or affecting creditors'
                  rights and to general equity principles, and the Shares, when
                  duly issued upon conversion, exercise or




The Goldman Sachs Group, Inc.                                                -3-


                  exchange of any such warrants that are convertible into or
                  exercisable or exchangeable for Shares, will be validly
                  issued, fully paid and nonassessable. The warrants covered by
                  the opinion in this paragraph include any warrants that may be
                  issued as part of the units or upon exercise or otherwise
                  pursuant to the terms of any other Securities, but they do not
                  include any Indenture Securities.

                           (3) Purchase Contracts Not Issued Under an Indenture.
                  When the Registration Statement has become effective under the
                  Act, when the terms of the governing instruments or agreements
                  under which certain of the purchase contracts are to be issued
                  have been duly established and the governing documents have
                  been duly executed and delivered, when the terms of such
                  purchase contracts and of their issuance and sale have been
                  duly established in conformity with the applicable governing
                  documents and when such purchase contracts have been duly
                  executed and authenticated in accordance with the applicable
                  governing documents and issued and sold as contemplated in the
                  Registration Statement, and if all the foregoing actions are
                  taken pursuant to the authority granted in the Resolutions and
                  so as not to violate any applicable law or result in a default
                  under or breach of any agreement or instrument binding upon
                  the Company and so as to comply with any requirement or
                  restriction imposed by any court or governmental body having
                  jurisdiction over the Company, such purchase contracts will
                  constitute valid and legally binding obligations of the
                  Company, subject to bankruptcy, insolvency, fraudulent
                  transfer, reorganization, moratorium and similar laws of
                  general applicability relating to or affecting creditors'
                  rights and to general equity principles, and the Shares, when
                  duly issued upon conversion, exercise or exchange of any such
                  purchase contracts that are convertible into or exercisable or
                  exchangeable for Shares, will be validly issued, fully paid
                  and nonassessable. The purchase contracts covered by the
                  opinion in this paragraph include any purchase contracts that
                  may be issued as part of the units or upon exercise or
                  otherwise pursuant to the terms of any other Securities, but
                  they do not include any Indenture Securities.

                           (4) Units Not Issued Under an Indenture. When the
                  Registration Statement has become effective under the Act,
                  when the terms of the unit agreements under which certain of
                  the units are to be issued have been duly established and the
                  unit agreements have been duly executed and delivered, when
                  the terms of such units and of their issuance and sale have
                  been duly established in conformity with the applicable unit
                  agreements and when such units have been duly executed and
                  authenticated in accordance with the applicable unit
                  agreements and issued and sold as contemplated in the
                  Registration Statement, and if all the foregoing actions are
                  taken pursuant to the authority granted in the Resolutions and
                  so as not to violate any applicable law or result in a default
                  under or breach of any agreement or instrument binding upon
                  the Company and so as to comply with any requirement or
                  restriction imposed by any court or governmental body having
                  jurisdiction over the Company, such units will constitute
                  valid and legally binding obligations of the Company, subject
                  to bankruptcy, insolvency, fraudulent transfer,
                  reorganization, moratorium and similar laws of general
                  applicability relating to or affecting creditors' rights and
                  to general equity principles. The units covered by the opinion
                  in this paragraph include any units that may be issued upon
                  exercise or otherwise pursuant to the terms of any other
                  Securities, but they do not include any Indenture Securities.

                           (5) Preferred Stock. When the Registration Statement
                  has become effective under the Act, when the terms of the
                  preferred stock and of its issuance and sale have been duly
                  established in conformity with the Company's certificate of
                  incorporation, when an appropriate certificate of designations
                  with respect to the preferred stock has been duly filed with
                  the Secretary of State of the State of Delaware and when the
                  preferred stock has been duly issued and sold as contemplated
                  by the Registration Statement, and if all the foregoing
                  actions are taken pursuant to the authority granted in the
                  Resolutions and so as not to violate any applicable law or
                  result in a default under or




                                                                            -4-

The Goldman Sachs Group, Inc.

                  breach of any agreement or instrument binding upon the Company
                  and so as to comply with any requirement or restriction
                  imposed by any court or governmental body having jurisdiction
                  over the Company, the preferred stock will be validly issued,
                  fully paid and non-assessable, and the Shares, when duly
                  issued upon conversion, exercise or exchange of any preferred
                  stock that is convertible into or exercisable or exchangeable
                  for Shares, will be validly issued, fully paid and
                  nonassessable. The preferred stock covered in the opinion in
                  this paragraph includes any preferred stock that may be
                  represented by depositary shares or may be issued upon
                  exercise or otherwise pursuant to the terms of any other
                  Securities.

                           (6) Depositary Shares. When the Registration
                  Statement has become effective under the Act, when the terms
                  of the deposit agreement under which the depositary shares are
                  to be issued have been duly established and the deposit
                  agreement has been duly executed and delivered, when the terms
                  of the depositary shares and of their issuance and sale have
                  been duly established in conformity with the deposit
                  agreement, when the preferred stock represented by the
                  depositary shares has been duly delivered to the depositary
                  and when the depositary receipts evidencing the depositary
                  shares have been duly issued against deposit of the preferred
                  stock in accordance with the deposit agreement and issued and
                  sold as contemplated by the Registration Statement, and if all
                  the foregoing actions are taken pursuant to the authority
                  granted in the Resolutions and so as not to violate any
                  applicable law or result in a


                                                                             -5-

The Goldman Sachs Group, Inc.

                  default under or breach of any agreement or instrument binding
                  upon the Company and so as to comply with any requirement or
                  restriction imposed by any court or governmental body having
                  jurisdiction over the Company, the depositary receipts
                  evidencing the depositary shares will be validly issued and
                  will entitle the holders thereof to the rights specified in
                  the depositary shares and the deposit agreement, subject to
                  bankruptcy, insolvency, fraudulent transfer, reorganization,
                  moratorium and similar laws of general applicability relating
                  to or affecting creditors' rights and to general equity
                  principles. The depositary shares covered by the opinion in
                  this paragraph include any depositary shares that may be
                  issued upon exercise or otherwise pursuant to the terms of any
                  other Securities.

                           (7) Assuming that the Rights Agreement has been duly
                  authorized, executed and delivered by the Rights Agent, then
                  when the Registration Statement has become effective under the
                  Act and the Shares have been validly issued upon conversion,
                  exercise or exchange of any Securities that are convertible
                  into or exercisable or exchangeable for Shares, the Rights
                  attributable to the Shares will be validly issued.

                  In connection with our opinion set forth in paragraph (7)
above, we note that the question whether the Board of Directors of the Company
might be required to redeem the Rights at some future time will depend upon the
facts and circumstances existing at that time and, accordingly, is beyond the
scope of such opinion.

                  We note that, as of the date of this opinion, a judgment for
money in an action based on a Security denominated in a foreign currency or
currency unit in a Federal or state court in the United States ordinarily would
be enforced in the United States only in United States dollars. The date used to
determine the rate of conversion of the foreign currency or currency unit in
which a particular Security is denominated into United States dollars will
depend upon various factors, including which court renders the judgment. In the
case of a Security denominated in a foreign currency, a state court in the State
of New York rendering a judgment on such Security would be required under
Section 27 of the New York Judiciary Law to render such judgment in the foreign
currency in which the Security is denominated, and such judgment would be
converted into United States dollars at the exchange rate prevailing on the date
of entry of the judgment.

                  The foregoing opinion is limited to the Federal laws of the
United States, the laws of the State of New York and the General Corporation Law
of the State of Delaware, and we are expressing no opinion as to the effect of
the laws of any other jurisdiction.

                  We have relied as to certain matters on information obtained
from public officials, officers of the Company and other sources believed by us
to be responsible. We have assumed, without independent verification, that the
indenture relating to the senior



                                                                             -6-

The Goldman Sachs Group, Inc.

debt securities has been duly authorized, executed and delivered by the trustee
thereunder, that all other governing documents under which the Securities are to
be issued, as well as the purchase contracts, if applicable, will have been duly
authorized, executed and delivered by all parties thereto other than the Company
and that the signatures on documents examined by us are genuine. We have further
assumed that the issuance or delivery by the Company of any securities other
than the Securities, or of any other property, upon exercise or otherwise
pursuant to the terms of the Securities will be effected pursuant to the
authority granted in the Resolutions and so as not to violate any applicable law
or result in a default under or breach of any agreement or instrument binding on
the Company and so as to comply with any requirement or restriction imposed by
any court or governmental body having jurisdiction over the Company. Finally, we
have assumed that the authority granted in the Resolutions will remain in effect
at all relevant times.

                  We are expressing no opinion as to any obligations that
parties other than the Company may have under or in respect of the Securities or
as to the effect that their performance of such obligations may have upon any of
the matters referred to above.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the reference to us under the heading
"Validity of the Securities" in the Prospectus. In giving such consent, we do
not thereby admit that we are in the category of persons whose consent is
required under Section 7 of the Act.

                                                   Very truly yours,

                                                   /s/ Sullivan & Cromwell LLP
