Ladies and Gentlemen:

                  We are acting as counsel to The Goldman Sachs Group, Inc., a
Delaware corporation (the "Company"), and to Goldman Sachs Capital II, Goldman
Sachs Capital III, Goldman Sachs Capital IV, Goldman Sachs Capital V and Goldman
Sachs Capital VI, each a Delaware statutory business trust (the "Trusts"), in
connection with their filing of a registration statement on Form S-3 (the
"Registration Statement") under the Securities Act of 1933 (the "Act"). The
Registration Statement registers $18,735,000,000 aggregate amount of the
following securities (collectively, the "Securities"):

             o    senior and subordinated debt securities, warrants, purchase
                  contracts, units comprised of the foregoing (or of capital
                  securities described below), preferred stock of the Company
                  and depositary shares representing preferred stock;

             o    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

                  LLC (successor to ChaseMellon Shareholder Services, L.L.C.),
                  as Rights Agent (the "Rights Agent");

             o    capital securities of the Trusts (the "Capital Securities"),
                  each representing an undivided, preferred beneficial interest
                  in the assets of the issuing Trust;

             o    guarantees and related obligations of the Company, on a
                  subordinated basis and to the extent provided therein, with
                  respect to the payment of distributions on and the redemption
                  or liquidation price of the Capital Securities or of similar
                  securities of other issuers similar to the Trusts (the
                  "Guarantees"); and

             o    subordinated debt securities to be issued by the Company to
                  the Trusts (or other similar issuers) in connection with the
                  issuance by the Trusts (or other similar issuers) of Capital
                  Securities (or similar securities) having corresponding
                  payment terms (the "Debentures").

                  In connection with the filing of the Registration Statement,
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, which is
             dated as of February 20, 2004, has been duly authorized, executed
             and delivered by the Company. The indenture relating to certain of
             the warrants, in the form filed as an exhibit to the Registration
             Statement, has been duly authorized by the Company. When the
             Registration Statement has become effective under the Act, when the
             indenture relating to certain of the warrants has been duly
             executed and delivered substantially in the form so filed, when the
             terms of the debt securities and the warrants to be issued under
             the three indentures described above (other than the Debentures,
             which we address below) (the "Indenture Securities") and of their
             issuance and sale have been duly established in conformity with the
             related indenture so as not to violate any applicable law or result
             in a default under or breach of any agreement or


                                      -2-

             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, but
             they do not include any Capital Securities, Guarantees or
             Debentures. 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 exchange
             of any such warrants that are convertible into or


                                      -3-

             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 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


                                      -5-

             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 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)  Rights. 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.

                 (8)  Guarantees and Debentures. When the Registration Statement
             has become effective under the Act, when the guarantee and related
             agreements under which the Guarantees are to be issued, the trust
             agreements under which the Capital Securities (and any other
             similar securities referenced in the first paragraph of this
             letter) are to be issued and the supplemental indentures under
             which (together with the related indenture referenced in paragraph
             (1) above) the Debentures are to be issued have been duly executed
             and delivered in substantially the forms filed as exhibits to the
             Registration Statement, when the terms of the Guarantees, the
             related Capital Securities (or any such other securities) and the
             corresponding Debentures and of their issuance have been duly
             established in conformity with the guarantee and related
             agreements, the trust agreements and the related indenture and
             supplemental indentures (and when the issuers of any such other
             securities have been duly formed), as applicable, 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 or the
             relevant Trust (or any such other issuer) and so as to comply with
             any requirement or restriction imposed by any court or governmental
             body having jurisdiction over the


                                      -6-

The Goldman Sachs Group, Inc.

             Company or the relevant Trust (or any such other issuer), and when
             the Guarantees, the related Capital Securities (or any such other
             securities) and the corresponding Debentures have been duly
             executed and (if required) authenticated in accordance with the
             guarantee and related agreements, the trust agreements and the
             related indenture and supplemental indentures, as applicable, and
             issued and sold by the Company and the respective Trusts (or any
             such other issuers), as applicable, as contemplated in the
             Registration Statement, and if all the foregoing actions are taken
             pursuant to the authority granted in the Resolutions, the
             Guarantees and the Debentures 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 Guarantees
             and Debentures covered by the opinion in this paragraph include any
             Guarantees and Debentures that, with the corresponding Capital
             Securities (or any such other securities), may be issued as part of
             the units or upon exercise or otherwise pursuant to the terms of
             any other Securities.

                  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 (except as stated below)
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. Notwithstanding
the foregoing, for the purposes of our


                                      -7-

opinion set forth in paragraph (8) above, we have assumed that, at all relevant
times, the Capital Securities (or any other similar securities referenced in the
first paragraph of this letter) and the related trust agreements will have been
duly executed and delivered by the respective Trusts (or the issuers of any such
other securities) and, in the case of the trust agreements, by the Company, the
Capital Securities (or any such other securities) will have been duly
authenticated, if required under the trust agreements, and the Capital
Securities (or any such other securities) and the trust agreements will
constitute valid and legally binding obligations of the respective Trusts (or
any such other issuers) and, in the case of the trust agreements, of the Company
under the laws of the State of Delaware, and we are expressing no opinion as to
such matters.

                  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 debt securities has been duly authorized,
executed and delivered by the trustee thereunder, that the indenture relating to
the subordinated 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 contained therein. 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
