(*)  Filed  as a  Post-Effective  Amendment  on  Form  S-8  to  such
     Registration  Statement  on Form F-4  pursuant to the  procedure  described
     herein in the section captioned "Explanatory Note."

                                EXPLANATORY NOTE

References to the "Company" and the "Registrant"  mean WPP Group plc, an English
public  limited  company.  References  to "Grey" mean Grey Global  Group Inc., a
Delaware corporation.

Under an Agreement  and Plan of Merger,  dated as of September  11, 2004, by and
among the Registrant, Abbey Merger Corporation, a wholly-owned subsidiary of WPP
("Abbey Merger") and Grey, as amended (the "Agreement and Plan of Merger"):  (1)
Grey will merge with and into Abbey  Merger (the  "Merger"),  with Abbey  Merger
surviving as a  wholly-owned  subsidiary of the Registrant and (2) each share of
common  stock,  par value $.01 per share,  of Grey  ("Grey  Common  Stock")  and
Limited  Duration  Class B common  stock,  par  value  $.01 per  share,  of Grey
outstanding will, subject to the election, allocation,  proration and adjustment
procedures set out in the Agreement and Plan of Merger,  be canceled in exchange
for the right to receive  either  $1,005 in cash or 21.746  American  Depositary
Shares of the  Registrant  (each an "ADS").  Each ADS  represents  five ordinary
shares,  nominal value 10p each, of the  Registrant  ("Ordinary  Shares").  Grey
stockholders  will  have  the  right to elect to  receive  the  Ordinary  Shares
represented  by all or a portion  of the ADSs such  stockholders  are  otherwise
entitled to  receive.  It is expected  that the Merger will be  effective  on or
about March 7, 2005 (the "Effective Time").

At the  Effective  Time,  all  options to purchase  shares of Grey Common  Stock
("Grey  Options")  that are  then  outstanding  and  unexercised  will  cease to
represent a right to acquire  Grey Common  Stock and (x) Grey  Options held by a
person  whose  primary   residence  or  employment  with  Grey  or  any  of  its
subsidiaries is in Europe will become options to acquire Ordinary Shares and (y)
all other Grey Options will become  options to acquire  ADSs.  At the  Effective
Time, each share of Grey Common Stock included in a participant's  account under
the Grey  Advertising Inc. 1998 Senior  Management  Incentive Plan ("1998 Plan")
and Grey Global Group Inc. 2003 Senior Management  Incentive Plan (together with
the 1998 Plan, the "Grey SMIP Plans") will be converted into Ordinary Shares (if
the  participant's  primary  place of  residence or  employment  with Grey is in
Europe) or into ADSs.

The Registrant  hereby amends its  Registration  Statement on Form F-4 (File No.
333-119949)  (the "Form F-4") by filing this  Post-Effective  Amendment No. 1 on
Form S-8 relating to up to 12,598,872  Ordinary  Shares,  subject to adjustment,
issuable upon the exercise of options granted  pursuant to the terms of the Grey
Advertising  Inc. 1994 Stock  Incentive Plan ("1994 Plan") or pursuant to awards
under the Grey SMIP Plans.

All such Ordinary Shares were previously  registered on the Form F-4 but will be
subject to issuance pursuant to this Post-Effective Amendment on Form S-8.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Article 136 of the Registrant's  Articles of Association  provides:

"Subject to the Statutes, every director or other officer (excluding an auditor)
of the Company shall be indemnified out of the assets of the Company against all
liabilities incurred by him in actual or purported execution or discharge of his
duty or the  exercise  or  purported  exercise  of his  powers or  otherwise  in
relation to or in connection with his duties, powers or offices but:

     (a)  this indemnity  shall not apply to any liability to the extent that it
          is recovered from any other person; and


                                     -II-1-

     (b)  the indemnity is subject to such officer taking all  reasonable  steps
          to effect such  recovery,  to the intent that the indemnity  shall not
          apply where an alternative  right of recovery is available and capable
          of being enforced."

     Section  310 of the  U.K.  Companies  Act  1985 (as  amended)  provides  as
follows:

         "310. PROVISIONS EXEMPTING OFFICERS AND AUDITORS FROM LIABILITY

     (1) This section applies to any provision, whether contained in a company's
articles or in any contract  with the company or  otherwise,  for  exempting any
officer of the company or any person (whether an officer or not) employed by the
company as auditor from, or  indemnifying  him against,  any liability  which by
virtue  of any rule of law  would  otherwise  attach  to him in  respect  of any
negligence, default, breach of duty or breach of trust of which he may be guilty
in relation to the company.

     (2) Except as provided by the following  subsection,  any such provision is
void.

     (3) This  section  does not  prevent  a  company

          (a)  from  purchasing and  maintaining for any such officer or auditor
               insurance  against any such liability,  or

          (b)  from  indemnifying  any  such  officer  or  auditor  against  any
               liability  incurred  by him

               (i)  in defending any proceedings  (whether civil or criminal) in
                    which judgment is given in his favour or he is acquitted, or

               (ii) in connection with any  application  under section 144(3) or
                    (4)  (acquisition of shares by innocent  nominee) or section
                    727  (general  power to grant  relief in case of honest  and
                    reasonable conduct) in which relief is granted to him by the
                    court."

     Section  727 of the  U.K.  Companies  Act  1985 (as  amended)  provides  as
follows:

             "727. POWER OF COURT TO GRANT RELIEF IN CERTAIN CASES:

     (1) If in any proceedings for negligence, default, breach of duty or breach
of trust  against an officer of a company or a person  employed  by a company as
auditor  (whether  he is or is not an officer of the  company) it appears to the
court  hearing  the case  that  that  officer  or  person is or may be liable in
respect to the negligence,  default, breach of duty or breach of trust, but that
he has  acted  honestly  and  reasonably,  and  that  having  regard  to all the
circumstances  of the case (including  those connected with his  appointment) he
ought fairly to be excused for the negligence, default, breach of duty or breach
of trust,  that  court may  relieve  him,  either  wholly  or  partly,  from his
liability on such terms as it thinks fit.

     (2) If any  such  officer  or  person  as  above-mentioned  has  reason  to
apprehend  that any claim  will or might be made  against  him in respect of any
negligence,  default,  breach of duty or  breach  of trust,  he may apply to the
court for relief; and the court on the application has the same power to relieve
him as under this  section it would have had if it had been a court before which
proceedings  against  that  person for  negligence,  default,  breach of duty or
breach of trust had been brought.

     (3) Where a case to which  subsection (1) applies is being tried by a judge
with a jury, the judge, after hearing the evidence, may, if he is satisfied that
the defendant or defender  ought in pursuance of that  subsection to be relieved
either in whole or in part from the liability sought to be enforced against him,
withdraw  the  case in whole or in part  from  the  jury  and  forthwith  direct
judgment to be entered for the  defendant  or defender on such terms as to costs
or otherwise as the judge may think proper."

The  Registrant  maintains  directors'  and officers'  insurance  coverage that,
subject to policy terms and limitations,


                                     -II-2-

will include  coverage to reimburse  the  Registrant  for amounts that it may be
required or permitted by law to pay directors or officers of Registrant.

(1) To file,  during  any  period in which  offers or sales  are being  made,  a
post-effective amendment to this Registration Statement;

     (i)  To  include  any  prospectus  required  by  Section  10(a)(3)  of  the
     Securities Act of 1933;

     (ii) To reflect in the  prospectus  any facts or events  arising  after the
     effective  date  of  this  Registration   Statement  (or  the  most  recent
     post-effective amendment thereof) which,  individually or in the aggregate,
     represent  a  fundamental  change  in the  information  set  forth  in this
     Registration Statement;

     (iii) To  include  any  material  information  with  respect to the plan of
     distribution not previously disclosed in this Registration Statement or any
     material change to such information in this Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1) (ii) do not apply if the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs  is  contained  in periodic  reports  filed with or  furnished to the
Commission  by the  Registrant  pursuant  to Section 13 or Section  15(d) of the
Securities  Exchange  Act of 1934 that are  incorporated  by  reference  in this
Registration Statement.

(2) That, for the purpose of determining  any liability under the Securities Act
of  1933,  each  such  post-effective  amendment  shall  be  deemed  to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

(3) To remove from  registration by means of a  post-effective  amendment any of
the securities  being  registered  which remain unsold at the termination of the
offering.

(b)  The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act (and, where  applicable,  each filing of an employee benefit plan's
annual  report   pursuant  to  section  15(d)  of  the  Exchange  Act)  that  is
incorporated by reference in the Registration  Statement shall be deemed to be a
new registration  statement relating to the securities offered therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

(c) Insofar as indemnification  for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
Registrant,  pursuant to the provisions described in Item 6 above, or otherwise,
the  Registrant  has been  advised that in the opinion of the  Commission,  such
indemnification  is against public policy as expressed in the Securities Act and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction  the  question  of whether or not such  indemnification  is against
public  policy as  expressed in the  Securities  Act and will be governed by the
final adjudication of such issue.
