the "Acquisition") and (ii) pursuant to a certain stock purchase agreement dated
as of May 11, 1995 between Holdings and Adelaide Horton (the "Advertising  Stock
Sale  Agreement" and the sale  thereunder  the  "Advertising  Stock Sale"),  (b)
following the Closing  under the  Acquisition  Agreement  (the  "Closing"),  the
amendment  of the  Certificate  of  Incorporation  of  Holdings  (the  "Holdings
Certificate")  to change the name of  Holdings to CDH  Corporation,  and (c) the
approval  and  adoption  of  a  plan  of  complete  liquidation  (the  "Plan  of
Liquidation")  pursuant to which  Holdings will (i) dissolve,  (ii)  establish a
liquidating  trust (the  "Liquidating  Trust")  pursuant to a liquidating  trust
agreement (the "Liquidating Trust Agreement"), between Holdings and Thomas Patty
and David C. Wiener, as trustees (the "Liquidating  Trustees"),  for the benefit
of its  stockholders,  and  (iii)  distribute  to its  stockholders  and/or  the
Liquidating Trust all its remaining assets (the "Liquidation" and, together with
the  Acquisition,  the Advertising  Stock Sale and the amendment to the Holdings
Certificate, the "Transactions").

      The Acquisition  Agreement provides a formula in which TBWA pays shares of
Omnicom Common Stock with an aggregate value (determined as more fully described
herein) of a base price which will be  $25,180,563  if the Closing  occurs on or
prior to August 31, 1995, or $25,930,880 if the Closing occurs between  November
1, 1995 and December 31, 1995, plus an amount equal to $2,418  multiplied by the
number of days  between the Closing and October 31, 1995 or December  31,  1995,
respectively. The aggregate acquisition price from the sale of assets to TBWA is
expected to be  $25,328,061  if the  Acquisition  is  consummated as expected on
August 31,1995, although it could range as high as $26,078,378 if consummated on
November 1, 1995.

     The approval of the various  proposals will require the affirmative vote of
the holders of a majority of the voting  power  represented  by the  outstanding
shares of Class A Common Stock and Class B Common  Stock,  voting  together as a
single class.  Directors and executive  officers of Holdings owning as of August
1, 1995  approximately  77.98% of Holdings  Common Stock in the  aggregate  have
expressed  a  present  intention  to  vote  in  favor  of the  Transactions  and
accordingly the  Transactions  can be approved by the  affirmative  vote of such
persons even if all other Holdings Stockholders vote against the proposals.

                               Omnicom  Common  Stock  for  distribution  to the

                               Omnicom  Common  Stock  reported  on the New York
                               Stock  Exchange  for the 20  consecutive  trading
                               days ending three business days immediately prior
                               to the Closing Date under, and as defined in, the
                               Acquisition  Agreement).  The number of shares of
                               Omnicom  Common  Stock  to  be  issued  shall  be
                               calculated and applied as follows:

                                    (a) TBWA will pay Holdings shares of Omnicom
                                        Common Stock having an aggregate  Market
                                        Value of (x) if the  Closing  is held on
                                        or  prior  to  October  31,  1995,   (i)
                                        $11,180,563 plus (ii) an amount equal to
                                        $2,418  multiplied by the number of days
                                        in the period  commencing on the Closing
                                        Date and ending on October 31, 1995,  or
                                        (y) if the Closing is held after October
                                        31, 1995 and on or prior to December 31,
                                        1995,  (iii)  $11,930,880  plus  (iv) an
                                        amount equal to $2,418 multiplied by the
                                        number of days in the period  commencing
                                        on  the  Closing   Date  and  ending  on
                                        December  31,  1995.   Of  this  Omnicom
                                        Common Stock,  shares having such Market
                                        Value as may be  necessary to insure the
                                        satisfaction  of obligations of Holdings
                                        and  Advertising  to the  Rightsholders,
                                        will be contributed to Advertising  (the
                                        "Contributed Stock").

                                    (b) TBWA  will  pay  Advertising  shares  of
                                        Omnicom Common Stock having an aggregate
                                        Market Value of $14,000,000.

   
                               It is  anticipated  that the  Closing  Date  will
                               occur on August 31,  1995,  which would result in
                               an  aggregate   purchase  price  of  $25,328,061.
                               Nevertheless,  the aggregate purchase price could
                               range  from  $26,078,378  to  $25,930,880  if the
                               Closing  is held  between  November  1,  1995 and
                               December 31, 1995.

                               Notwithstanding  the foregoing,  the  Acquisition
                               Agreement  provides that prior to the Closing the
                               parties  will  negotiate in good faith an upwards
                               adjustment  to  the  acquisition   price  if  the
                               "Annualized   Revenues"   of  Holdings   and  its
                               subsidiaries,  being  the  commissions  and  fees
                               expected  to  be  earned  by  Holdings   and  its
                               subsidiaries  from  clients  who are  such at the
                               time  of the  calculation  for  the  fiscal  year
                               ending  October 31, 1995 (the "1995 Fiscal Year")
                               exceed  $100,000,000 and the profits before taxes
                               (as adjusted to exclude net interest  expense and
                               certain  other items agreed  between the parties)
                               ("EBIT") of Holdings and its subsidiaries for the
                               1995 Fiscal Year is reasonably expected to exceed
                               $17,200,000.  If an  upwards  adjustment  is  not
                               agreed,   Holdings   has  the   right  to  either
                               terminate  the  Acquisition  Agreement or proceed
                               with  the  Closing  at the  original  price.  Any
                               additional  consideration payable will be made in
                               shares  of  Omnicom  Common  Stock  valued at the
                               Market Value. However, based on operating results
                               of Holdings and its subsidiaries achieved through
                               July 31,  1995,  it is highly  unlikely  that any
                               such adjustment will occur.

                               On the date on which Omnicom publishes  financial
                               results  covering  at least  30 days of  combined
                               operations  for Omnicom and the  Businesses  (the

                               Advertising Stock Sale Agreement".

Distribution Date ..........   The distributions of the shares of Omnicom Common
                               Stock by Holdings and Advertising  will not occur
                               until the  "Distribution  Date". The Distribution
                               Date will be the date of  publication  by Omnicom
                               of financial results covering at least 30 days of
                               combined   operations   for   Omnicom   and   the
                               Businesses after the Closing Date,  provided that
                               if the  Closing  occurs on or prior to August 31,
                               1995, the  Distribution  Date will be the earlier
                               of the date of such  publication  and October 30,
                               1995 (whether or not such  financial  results are
                               published).  Assuming  the  Closing  occurs on or
                               before  August 31, 1995,  the earliest  that such
                               financial  results  would be published is October
                               26, 1995. During the period from the Closing Date
                               through   the   Distribution    Date,    Holdings
                               Stockholders and Rightsholders will bear the risk
                               of  fluctuations  in  the  market  price  of  the
                               Omnicom Common Stock.

Payment of Obligations
to Rightsholders ...........   In 1993 and 1988,  Holdings  adopted the EAR Plan
                               and EPU Plan, respectively, and has issued awards
                               under  such  Plans.   If  the   employment  of  a
                               participant  is terminated  for any reason,  then
                               under the terms of the EAR Plan, such participant
                               shall have the right, but not the obligation,  to
                               cause Holdings or  Advertising  to, and under the
                               EPU Plan Holdings or  Advertising  shall,  redeem
                               vested  units for cash in each case at their book
                               value  as at the end of the  most  recent  fiscal
                               quarter.  At April 30, 1995,  such book value was
                               less  than  zero.  However,  in  the  event  of a
                               liquidation, with respect to their priority, each
                               EAR and EPU shall be deemed  equivalent  in value
                               to one share of Holdings  Common  Stock and shall
                               be treated in the same manner as Holdings  Common
                               Stock.  Therefore,   Rightsholders  will  receive
                               shares of Omnicom  Common Stock as payment  under
                               such  Plans,   subject  to  the  same  terms  and
                               conditions as if they were Holdings Stockholders,
                               including  without   limitation  the  escrow  and
                               indemnification  provisions  more fully described
                               herein.

Per Share and Per Right
Consideration ..............   The total  value of  Omnicom  Common  Stock to be
                               paid by TBWA to Holdings and Advertising pursuant
                               to the Acquisition Agreement will be dependent on
                               when the Closing Date occurs (as described  above
                               and  as   more   fully   described   under   "The
                               Acquisition     Agreement--The      Acquisition--
                               Determination of Acquisition Price"). In order to
                               make   certain   estimates    relating   to   the
                               consideration   to  be  paid   to  the   Holdings
                               Stockholders  and  the  Rightsholders  which  are
                               included    in    this     Prospectus/Information
                               Statement,  it has been  assumed that the Closing
                               Date will occur on August 31, 1995 and the Market
                               Value of the Omnicom Common Stock will be $563/8.
                               Based on an estimated total  acquisition price of
                               $25,328,061, after deposits are made on behalf of
                               the Holdings  Stockholders and Rightsholders into
                               the General Escrow Fund, the Special Escrow Fund,
                               the Liquidating  Trust and the Liquidating  Trust
                               Escrow Fund (as applicable), each holder of Class
                               A Common Stock,  Class B Common  Stock,  EPUs and

                               EARs will be entitled to receive in a liquidating
                               distribution,  per share of Holdings Common Stock
                               or per EPU or EAR, shares of Omnicom Common Stock
                               with a value  (determined in accordance  with the
                               terms  of the  Acquisition  Agreement)  equal  to
                               $0.178.  The remaining  shares of Omnicom  Common
                               Stock received by Holdings and  Advertising  will
                               be used to fund  the  Liquidating  Trust  and the
                               Liquidating  Trust  Escrow  Fund,  which  will be
                               responsible for taxes and the expenses of winding
                               up the affairs of  Holdings,  as well as possible
                               contingent  liabilities,  and to fund the General
                               Escrow   Fund  and  the   Special   Escrow   Fund
                               (individually sometimes referred to as an "Escrow
                               Fund" and  collectively  as the "Escrow  Funds").
                               Based  upon   current   estimates  of  taxes  and
                               expenses,   if   there   were   no   claims   for
                               indemnification or other contingent  liabilities,
                               each Holdings  Stockholder and Rightsholder would
                               be  entitiled to receive upon the release of such
                               funds from the  applicable  trust and/or  escrows
                               shares of Omnicom  Common Stock with an aggregate
                               value (determined in accordance with the terms of
                               the Acquisition Agreement) equal to approximately
                               $0.037,  for a total per share or per unit  value
                               equal to approximately  $0.215. 
    

                               Since the amounts  held in such  escrows and such
                               trust  are   subject  to  claims  in  respect  of
                               contingent   liabilities,   there   can   be   no
                               assurances that amounts held therein will in fact
                               be  distributed  to  Holdings   Stockholders  and
                               Rightholders.

                               See   "The   Plan   of   Liquidation--Liquidating
                               Distribution   to  Holdings   Stockholders"   and
                               "--Liquidating Distribution to Rightsholders".

Escrow Agreement and
Indemnification ............   Obligations   The   obligation   of  Holdings  to
                               indemnify  Omnicom  and TBWA  against  losses and
                               damages may arise in one of two ways: pursuant to
                               the general indemnification obligations under the
                               Acquisition   Agreement,   or  as  a  result   of
                               inaccurate or misleading  information supplied by
                               Holdings  for use in this  Prospectus/Information
                               Statement.

   
                               The indemnification obligations of Holdings under
                               the Acquisition  Agreement will be limited to and
                               satisfied  solely from the Escrow Funds under the
                               Escrow  Agreement  (such that neither Omnicom nor
                               TBWA nor any of their  affiliates  will  have any
                               recourse  for the  payment of any losses or other
                               damages   of  any  kind   against   Holdings   or
                               Advertising  or their  respective  affiliates  or

                               separated    into    two    sub-accounts:     the

                               of the General  Escrow Fund will terminate on the

                               any,  of TBWA and the  Businesses  following  the

                               of the  Special  Escrow  Fund will  terminate  no

                               will be distributed to the Liquidating  Trust and

                               will satisfy its pro rata share of the applicable
                               category of losses  based on the number of shares
                               of Omnicom  Common  Stock then on deposit in such

                               The indemnification obligations of Holdings which
                               may arise to the extent it  furnishes  inaccurate

                               of   Holdings   remaining   after   the   initial
                               distributions  of Omnicom Common Stock  described
                               above under "--The  Acquisition" (these remaining
                               assets are expected to be  nominal).  Pursuant to
                               the  terms  of the  Liquidating  Trust  Agreement
                               governing the operation of the Liquidating Trust,
                               each share of Holdings  Common Stock,  regardless
                               of class,  shall  have an equal  interest  in the
                               Liquidating Trust.
    

                               The Liquidating  Trust will be funded,  on behalf
                               of the Holdings  Stockholders,  with five percent
                               of the  Omnicom  Common  Stock  paid  by  TBWA to
                               Holdings as part of the  acquisition  price under
                               the Acquisition  Agreement  (after  deducting the
                               Contributed  Stock).  The  Liquidating  Trust may
                               also receive from time to time,  on behalf of the
                               Holdings  Stockholders,  distributions of Omnicom
                               Common Stock  pursuant to the terms of the Escrow
                               Agreement.

                               The  Liquidating  Trustees  will  distribute  the
                               assets in the  Liquidating  Trust to the Holdings
                               Stockholders,  pro rata in accordance  with their
                               interests, as expeditiously as possible, provided
                               that adequate  reserves  shall be taken for Trust
                               Liabilities (as defined  below),  expenses of the
                               Liquidating   Trustees   (which   shall   include
                               ordinary  and  customary  expenses)  and to  make
                               distributions   to  any  missing   beneficiaries.
                               Payments  made  from  the  Liquidating  Trust  to
                               satisfy such  liabilities  will be  reimbursed in
                               part from the Liquidating Trust Escrow Fund.

                               See  "The  Plan  of   Liquidation--General"   and
                               "--Operation of the Liquidating Trust".

The Liquidating
Trust Escrow Fund ..........   The Liquidating Trust Escrow Fund will be funded,
                               on behalf of the Rightsholders, with five percent
                               of the  Omnicom  Common  Stock  paid  by  TBWA to
                               Advertising  as  part  of the  acquisition  price
                               under the Acquisition  Agreement  (including five
                               percent   of   the   Contributed    Stock).   The
                               Liquidating  Trust  Escrow Fund may also  receive
                               from   time   to   time,   on   behalf   of   the
                               Rightsholders,  distributions  of Omnicom  Common
                               Stock   pursuant  to  the  terms  of  the  Escrow
                               Agreement.

                               The Liquidating Trust Escrow Fund will be used to
                               satisfy   the   Rightsholders'   share  of  Trust
                               Liabilities.

                               Whenever   the   Liquidating   Trustee   makes  a
                               distribution  of trust  property to the  Holdings
                               Stockholders,   a  proportionate  amount  of  the
                               Liquidating Trust Escrow Fund will be distributed
                               to the Rightsholders, pro rata in accordance with
                               their interests.

                               See  "The  Plan of  Liquidation--The  Liquidating
                               Trust Escrow".

                              Other Considerations

Recommendation of the Board
of Directors of Holdings ...   The Board of Directors of Holdings,  by unanimous
                               vote,  approved each of the matters  constituting
                               part  of the  Transactions,  and  recommends  the
                               approval of each of such  matters by the Holdings
                               Stockholders.

   
Interests of Certain Persons
in the Transactions ........   As of August 1,  1995,  directors  and  executive
                               officers of Holdings owned of record an aggregate
                               of 77.98% of the  outstanding  shares of Holdings
                               Common Stock.  Accordingly,  the Transactions can
                               be approved  without the affirmative  vote of any
                               other   Holdings   Stockholders.   Each  of  such
                               directors and executive officers has expressed an
                               intention  to vote the shares of Holdings  Common
                               Stock  owned  by  him  or  her  in  favor  of the
                               Transactions.

                               As of August 1,  1995,  directors  and  executive
                               officers of Holdings owned of record an aggregate
                               of 84.44% of the outstanding awards under the EAR
                               and  EPU  Plans.   Each  of  such  directors  and
                               executive officers have executed and delivered to
                               Holdings  his or her Consent  Letter as described
                               above.
    

                               For a description of certain interests of certain
                               directors and  executive  officers of Holdings in
                               the  Transactions  that  are in  addition  to the
                               interests of Holdings Stockholders generally, see
                               "The  Transactions--Interests  of Certain Persons
                               in the Transactions".

Accounting Treatment .......   The Acquisition  will be accounted for by Omnicom
                               as    a     pooling-of-interests.     See    "The
                               Transactions--Accounting Treatment".

Federal Income
Tax Consequences ...........   The Acquisition will be a taxable  transaction to
                               Holdings and Advertising;  and the  distributions
                               pursuant  to the  Plan of  Liquidation  will be a
                               taxable transaction to Holdings  Stockholders and
                               Rightsholders.  Holders  of Class A Common  Stock
                               and of Class B Common Stock issued in July,  1989
                               pursuant to a certain  stock  purchase  agreement
                               between Holdings and certain management and other
                               investors  ("Mojo B Common Stock") will recognize
                               gain  or  loss as a  result  of the  Transactions
                               equal to the  difference  between  the sum of (i)
                               the fair market value of all Omnicom Common Stock
                               received  (whether  distributed  or placed in the
                               Liquidating Trust or the Stockholders  General or
                               Special Escrow Funds) plus (ii) the cash received
                               in respect of any  fractional  shares,  and their
                               adjusted  basis in the  Class A  Common  Stock or
                               Mojo B Common  Stock.  Holders  of Class B Common
                               Stock  other  than the Mojo B Common  Stock  will
                               recognize compensation income equal to the excess
                               of the sum of (a) the  fair  market  value of the
                               Omnicom    Common   Stock    received    (whether
                               distributed or placed in the Liquidating Trust or
                               the Stockholders General or Special Escrow Funds)
                               plus  (b) the cash  received  in  respect  of any
                               fractional shares, over the sum of (x) the amount
                               paid for their Class B Common Stock,  and (y) the
                               amount,  if any,  of ordinary  income  which they
                               have  previously  recognized  in respect of their
                               Class B Common Stock.

                               computing his or her federal income tax.

                               Rightsholders will recognize  compensation income
                               equal to the  fair  market  value of the  Omnicom

                               or  not  distributed)  in  computing  his  or her
                               federal income tax.

                           COMPARATIVE PER SHARE DATA

   
     Set forth below are  unaudited  income  from  continuing  operations,  cash
dividends  declared and book value per common share data of Omnicom and Holdings
on both historical and pro forma combined bases.  Pro forma combined income from
continuing  operations  per share is calculated  under the  pooling-of-interests
accounting  method and assumes that the  Acquisition  had  occurred  immediately
prior to the period being reported upon. Since Omnicom is on a calendar year for
financial  reporting  purposes,  while Holdings' fiscal year ends on October 31,
the combined results for the three months ended March 31, 1995 and for each year
in the three years ended  December 31,  1994,  respectively,  reflect  Omnicom's
results for those  periods and  Holdings'  results  for the three  months  ended
January 31, 1995,  and for each year in the three years ended  October 31, 1994.
Pro forma  combined  cash  dividends  declared per share  reflects  Omnicom cash
dividends declared in the periods indicated.  The per share equivalent pro forma
combined data has been calculated  based upon the material  assumptions that the
aggregate  acquisition  price will be  $25,328,061,  and the Market Value of the
Omnicom Common Stock will be $563/8.  The  information set forth below should be
read  in  conjunction  with  the  respective  audited  and  unaudited  financial
statements of Omnicom  incorporated by reference in this  Prospectus/Information
Statement and of Holdings included in this Prospectus/Information Statement.

           Background of and Holdings' Reasons for the Transactions;
               Recommendation of the Holdings Board of Directors

Overview

     After  the  Closing,   the  Businesses  will  be  combined  with  the  TBWA
International  network  of  companies  to form a  combined  advertising  network
operating as one  integrated  unit. In  furtherance  of this, the members of the
TBWA  International  group  operating  under the TBWA name in North America will
change their corporate names to include the designation  "TBWA  Chiat/Day".  See
"Interests of Certain  Persons in the  Transactions"  for a  description  of the
positions within this integrated  network that will be held by certain executive
officers of Holdings and its subsidiaries.

     The terms of the Acquisition,  including the terms of the Escrow Agreement,
are the result of arm's-length  negotiation  between  representatives of Omnicom
and TBWA and representatives of Holdings and Advertising.

Background of the Transactions

     In early 1993, Holdings commenced exploring strategic alternatives in order
to expand  internationally  and  reduce  the debt on its  balance  sheet.  These
alternatives  included  possible  strategic  combinations with other advertising
agencies and groups,  including Omnicom.  Preliminary discussions were held with
parties  other  than  Omnicom  but  such  discussions  did not  lead to  serious
negotiations.   Holdings  and  Omnicom  began  informally   discussing  possible
combinations in 1993 shortly after Omnicom acquired TBWA, but at such time these
discussions did not advance to substantive  negotiations and ceased. Since 1993,
however,  TBWA and  Holdings  frequently  consulted  with respect to their joint
representation of Nissan.

   
     In late 1994 and January  1995,  Holdings was engaged in  discussions  with
potential  lenders  regarding the  refinancing of its bank credit  facility (the
"Bank  Credit  Agreement")  which was to mature in May 1995 and $11  million  of
Holding's 13.25% Senior  Subordinated  Notes which matured and were paid in full
on August 1, 1995.  The terms  proposed  by  prospective  institutional  lenders
included  substantial  penalties for early  repayment  and the  equivalent of an
equity  participation  in  Holdings  in the event  that it were sold  while such
financing was outstanding. During the period Holdings was considering whether to
accept such terms of  refinancing,  discussions  with  Omnicom  were renewed and
began to assume the characteristics of negotiations in January of 1995. Holdings
realized that to proceed with the proposed  refinancing would create significant
obstacles to consummating any acquisition  transaction.  Instead, Omnicom agreed
to assume the  liabilities  of the banks  under the Bank  Credit  Agreement  and
extended the  maturity  until  December  10, 1995 (as assumed and  amended,  the
"Amended and Restated Credit Agreement").
    

     The negotiations with Omnicom  concerning a possible  combination with TBWA
and Holdings  continued  through  January and on February 1, the parties reached
preliminary  agreement  in principle  and a public  announcement  was made.  The
negotiations  continued  through March and April 1995 and  culminated on May 11,
1995 in the  execution  of the  definitive  Acquisition  Agreement  and  related
documents following approval by the Board of Directors of each company.


                                       21

Holding's Reasons for the Transactions

     The  decision  of the Board of  Directors  of  Holdings  to enter  into the
Acquisition  was largely  influenced by the Board's  assessment of the perceived
benefits of a strategic combination with TBWA in the United States and Europe as
well as the limited growth  opportunities of an independent Holdings in light of
its highly leveraged balance sheet. The Board also took into  consideration that
the  shareholders  of Holdings,  including  the Profit  Sharing  Plan,  had been
holding for a significant period of time an illiquid investment in Holdings. The
Board of Directors  believes  that the  Acquisition  offers a fair price for the
assets of Holdings and Advertising,  provides the Holdings Stockholders a liquid
investment and that the  combination  with TBWA  contemplated by the Acquisition
provides  an  excellent  strategic  fit and the  increased  liquidity  needed to
capitalize on growth opportunities for the combined organization.

     The  Holdings  Board  of  Directors  made  its  determination  without  the
assistance of a financial advisor and without a "fairness opinion". Instead, the
Holdings Board of Directors has relied upon its own experience and the knowledge
of  its  management  in  assessing  the  advantages  and  disadvantages  of  the
Transactions.

Recommendation of the Holdings Board of Directors

     For the reasons set forth above,  the Holdings Board of Directors  believes
that the  Transactions  are fair to, and in the best interests of,  Holdings and
the Holdings Stockholders and recommends that the Holdings Stockholders vote FOR
the  approval  of  the  sale  of the  assets  and  businesses  of  Holdings  and
Advertising pursuant to the Acquisition Agreement and the Advertising Stock Sale
Agreement,  FOR the approval of the amendment of the Holdings  Certificate,  and
FOR the approval of the Plan of Liquidation.

                     Omnicom's Reasons for the Acquisition

     Omnicom's and TBWA's  respective  Board of Directors each believes that the
Acquisition  represents an opportunity  for TBWA to strengthen its position as a
major  global  advertising  agency  network  without   diminishing  its  overall
financial strength. TBWA's international strength is concentrated outside of the
United  States,  while  Holdings and  Advertising  have a strong North  American
presence;  the  Acquisition  is  therefore a natural  geographic  fit which will
expand TBWA's worldwide capabilities.

     The fit is also strategic from a client servicing perspective.  Advertising
is the  advertising  agency of record in the  United  States  and Canada for the
Nissan and Infiniti  divisions of the Nissan Motor Corp.; while TBWA handles the
Nissan  business  on a Pan  European  basis as well as the local  business  in 9
European countries.  The Acquisition represents an opportunity to strengthen the
Nissan relationship by being in a position to service this client throughout the
world.

     The Boards of  Directors  of Omnicom and TBWA  believe  that the  corporate
cultures  of  the  two  networks  will  combine  well,  as  both  networks  have
historically  placed  their major  emphasis on  creative  output.  The Boards of
Directors of TBWA and Omnicom also  considered  the  potential  synergies  which
would result in lower costs as a result of the combining of the operations.

     Omnicom  has not  retained  an  outside  party  to  evaluate  the  proposed
Acquisition  but has instead  relied upon the  knowledge  of its  management  in
considering the financial aspects of the Acquisition.

     In reaching  its  conclusion,  the Board of  Directors  of Omnicom and TBWA
considered,  among  other  things:  (i)  information  concerning  the  financial
performance,  condition,  business  operations and prospects of each of Holdings
and  Advertising;  and (ii) the proposed terms and structure of the Acquisition.
It is anticipated that the Acquisition will be non-dilutive to Omnicom's results
of operations.  Accordingly,  the Board of Directors of Omnicom has  unanimously
approved the Acquisition Agreement and the transactions contemplated thereby.

                Interests of Certain Persons in the Transactions
    

     (The following  describes  certain interests of the directors and executive
officers of Holdings in the  Transactions  that are in addition to the interests
of Holdings Stockholders generally.)

Employment and Consulting Agreements; Non-Competition Agreements

   
     Pursuant  to the  Acquisition  Agreement,  the  employment  and  consulting
agreement  dated May 11, 1995 between Jay Chiat and Holdings  will be assumed by
TBWA and then assigned to Omnicom.  Upon the completion of the Acquisition,  Mr.
Chiat will serve as a consultant  under the employment and consulting  agreement
and will serve as such until the seventh  anniversary  of the Closing Date,  and
the agreement  automatically  extends until the earlier of the tenth anniversary
of the Closing Date or such earlier date on which  Holdings no longer  maintains
certain key client relationships.  Mr. Chiat's compensation in Omnicom's opinion
is reasonable for the services he is to render and in any event is significantly
less than he was earning  immediately  prior to the Acquisition.  Mr. Chiat will
not be provided with any employee benefits.  In addition,  pursuant to the terms
of the  Acquisition  Agreement,  Mr.  Chiat will  enter  into a  non-competition
agreement  with  Omnicom  which will have a term of 10 years  commencing  on the
Closing Date of the Acquisition.  No additional consideration is being paid with
respect to such non-competition agreement.

     Pursuant to the Acquisition  Agreement,  the employment agreement dated May
11,  1995  between  Leland  Clow and  Holdings  will be  assumed  by TBWA.  Such
employment agreement extends to December 31, 1998 and provides for annual salary
compensation  at the  same  levels  as  the  predecessor  employment  agreement.
Following the consummation of the  Acquisition,  Mr. Clow's salary level will be
subject to increases in connection with the salary review procedures of TBWA and
Mr. Clow will participate in TBWA bonus plans. Benefits substantially equivalent
to those Mr. Clow was receiving under his predecessor  employment agreement will
also  be  provided.  In  addition,  pursuant  to the  terms  of the  Acquisition
Agreement,  Mr. Clow will enter into a  non-competition  agreement  with Omnicom
which will have a term  commencing  on the Closing Date of the  Acquisition  and
ending on the later of December 31, 1998 or two years after the  termination  of
Mr. Clow's employment. No additional consideration is being paid with respect to
such non-competition agreement.
    

     Pursuant to the Acquisition  Agreement,  TBWA or one of its affiliates will
enter into employment  agreements with Steve Hancock,  the  President/CEO of the
Toronto office of Advertising,  and each of the following key executive officers
who are also  directors of  Holdings:  Adelaide  Horton;  Robert  Kuperman;  Ira
Matathia;  and Tom Patty. It is anticipated that the employment  agreements will
have a term  commencing  on the Closing  Date of the  Acquisition  and ending on
December 31, 1998 and provide for annual salary compensation and fringe benefits
substantially  equivalent to those such persons were receiving immediately prior
to the  Acquisition.  Such persons will also be eligible to  participate in TBWA
bonus plans. In addition,  the Acquisition  Agreement provides that Robert Wolf,
also a  director  of  Holdings,  will enter into an  employment  agreement  with
Omnicom with a term ending on December 31, 1996. Mr. Wolf's employment agreement
provides for the same annual  salary he was receiving  immediately  prior to the
Acquisition and benefits customarily provided by Omnicom to its employees.

     Pursuant to the terms of the  Acquisition  Agreement,  the  executives  and
directors  listed in the first sentence of the immediately  preceding  paragraph
and Mr. Wolf will enter into non-competition  agreements with Omnicom which will
have a term  commencing on the closing date of the Acquisition and ending on the
later of  December  31, 1998 or two years after  termination  of the  applicable
party's  employment.   There  is  no  additional  consideration  being  paid  in
connection with these non-competition agreements.

     In  connection  with  the  Transactions,   a  1987  deferred   compensation
arrangement  between  Advertising  and Robert  Kuperman  will be canceled by the
payment of the present value of the vested  benefits  thereunder.  The liability
for such vested benefits has already been recorded on the books of Advertising.

     The terms of the Acquisition  Agreement  permit Holdings and Advertising to
pay to their  directors and employees  bonuses accrued for fiscal year 1994, and
permit  Advertising  to accrue for bonuses for the 1995 Fiscal Year an amount up
to 10% of profit from normal advertising  operations before all federal,  state,
local and  foreign  income  taxes and  adjusted to exclude  interest  income and
interest  expense,  with such  accrual to be  reviewed  and  adjusted  upward or
downward after  completion of the 1995 Fiscal Year consistent with past practice
(provided  that for the period from the Closing Date  through  October 31, 1995,
the  accrual  shall be based  on the  financial  results  of the  Businesses  as
conducted  by TBWA).  Holdings  has  established  a bonus pool of  approximately


                                       23
<PAGE>

$2,500,000  with respect to fiscal year 1994,  40% of which will be allocated to
its senior officers,  all of whom are directors.  Bonuses with respect to Fiscal
Year  1995  have  not yet  been  determined,  but it is  expected  that all or a
substantial  portion of such  bonuses will be paid to the same  individuals.  In
addition,  if such  profits  exceed  budgeted  amounts for the 1995 Fiscal Year,
additional bonus payments will be made.

     Pursuant to the Acquisition  Agreement,  all other employees of Holdings or
Advertising  (many  of whom  are  stockholders  of  Holdings)  will  be  offered
employment by TBWA or its affiliates on substantially  equivalent terms as their
employment prior to the Acquisition.

Other Agreements

   
     Prior  to  the  Closing  Date,   Holdings  will  redeem  its  8.17%  Junior
Subordinated Installment Notes due 2005 and its 13.25% Junior Subordinated Notes
due 2005  (collectively,  the "Junior  Notes") at their face value plus  accrued
interest  to the  date  of  redemption.  Jay  Chiat,  a  director  of  Holdings,
beneficially  owns  $3,522,000 in principal  amount of the Junior Notes and will
receive $5,328,001 as a result of this redemption.  The funds required to redeem
such notes shall be borrowed from TBWA;  see "The  Acquisition  Agreement--Other
Terms and Conditions of the Acquisition Agreement--Financial Actions."
    

     Pursuant to the  Acquisition  Agreement,  certain works of art owned by Mr.
Chiat  will be leased to TBWA on the same basis as the art is  currently  leased
for a  nominal  sum  commencing  on  the  consummation  of the  Acquisition.  In
connection  with such lease,  TBWA will pay for the costs of insuring such works
of art against  theft,  loss and damage.  The lease will be terminable  upon one
month's notice by either party thereto.

   
     Following the  Distribution  Date, Ms. Horton  (together with any permitted
assignees)  will purchase from Holdings for $250,000 in cash,  all of the issued
and outstanding  common stock of Advertising  pursuant to the Advertising  Stock
Sale Agreement.  At the time of such purchase,  the only asset which Advertising
will own will be its rights,  through its  ownership of all of the capital stock
of Chiat/Day Direct  Marketing,  Inc., under the litigation  entitled  Chiat/Day
Direct Marketing,  Inc. f/k/a/  Perkins/Butler Direct Marketing Inc. v. National
Car Rental Systems, Inc., No. 93 Civ. 2717 (S.D.N.Y.)(the  "National Car Suit").
Pursuant  to the  Advertising  Stock  Sale  Agreement,  Holdings  has  agreed to
indemnify  Ms.  Horton and  Advertising  for any losses  incurred  in respect of
liabilities of Advertising not assumed by TBWA under the Acquisition  Agreement.
To the extent  that  Holdings  were  unable to fully  indemnify  Ms.  Horton and
Advertising,  any recovery  from the National Car Suit  received by  Advertising
would be at risk.  The Board of Directors of Holdings  believes that the sale of
Advertising  toMs.  Horton is on terms no less  favorable to Holdings than would
result from an arms-length  negotiation  conducted with unrelated  parties.  See
"The Advertising Stock Sale Agreement".
    

     David C. Wiener and Company, P.C., of which David C. Wiener is a principal,
will  receive  fees  for  services  rendered  to  Holdings  and  Advertising  in
connection  with  the  Acquisition  in  an  aggregate  amount  estimated  to  be
approximately  $350,000.  Mr.  Wiener is a member of the Board of  Directors  of
Holdings.

     Prior  to the  consummation  of the  Acquisition,  pursuant  to the  Profit
Sharing Plan Purchase Agreement the shares of Preferred Stock held in the Profit
Sharing Plan are being acquired by Holdings for  $14,081,773.93  in cash. All of
the  directors  and  senior  executive   officers  of  Holdings  (together  with
approximately 600 other employees),  other than Mr. Wiener,  are participants in
such plan.

     See also  "Description of Holdings  Capital Stock" for a description of the
security ownership of management of Holdings.

                              Accounting Treatment

     The Acquisition will be accounted for by Omnicom as a  pooling-of-interests
for  financial   reporting   purposes  in  accordance  with  generally  accepted
accounting principles.  Accordingly,  upon consummation of the Acquisition,  the
assets and  liabilities  of  Holdings  and  Advertising  will be included in the
consolidated  balance sheet of Omnicom and its subsidiaries in the amounts which
were  included  in the books of  Holdings  immediately  before the  Acquisition,
subject to adjustments  required to conform the accounting  policies of Holdings
to those utilized by Omnicom,  and such other adjustments as may be necessary to
comply with pooling-of-interests accounting rules and regulations.

                              Regulatory Approvals

     Under the  Hart-Scott-Rodino Act and the rules promulgated therewith by the
FTC, the Acquisition may not be consummated until  notifications have been given
and certain information has been furnished to the FTC and the Antitrust Division
and specified  waiting  period  requirements  have been  satisfied.  Omnicom and


                                       24
<PAGE>

   
Holdings filed  notification  and report forms under the  Hart-Scott-Rodino  Act
with the FTC and the  Antitrust  Division  on June 27,  1995 and June 28,  1995,
respectively.  The required waiting period under the  Hart-Scott-Rodino  Act was
terminated early on July 11, 1995.
    

     At any time before or after consummation of the Acquisition,  the Antitrust
Division or the FTC could take such action under the antitrust  laws as it deems
necessary or desirable in the public interest,  including  seeking to enjoin the
consummation of the Acquisition or seeking  divestiture of assets of Omnicom. At
any  time  before  or after  the  Closing  Date,  and  notwithstanding  that the
Hart-Scott-Rodino  Act  waiting  period has  expired,  any state could take such
action under the antitrust laws as it deems necessary or desirable in the public
interest.  Such action could include  seeking to enjoin the  consummation of the
Acquisition  or seeking  divestiture of assets of Omnicom.  Private  parties may
also  seek  to  take  legal  action  under  the  antitrust  laws  under  certain
circumstances.

   
     Based on information  available to them,  Omnicom and Holdings believe that
the  Acquisition  can be effected in compliance with federal and state antitrust
laws. However, there can be no assurance that a challenge to the consummation of
the  Acquisition  on  antitrust  grounds  will  not be made or  that,  if such a
challenge were made, Omnicom and Holdings would prevail or would not be required
to accept certain conditions,  possibly including certain divestitures of assets
of Omnicom, in order to consummate the Acquisition.
    
       

                              Resale Restrictions

     All shares of Omnicom  Common Stock received by Holdings  Stockholders  and
Rightsholders as a result of the Acquisition will be freely transferable, except
that  shares of Omnicom  Common  Stock  received by persons who are deemed to be
"affiliates"  (as such term is understood  under the Securities Act) of Holdings
prior to the  Acquisition  ("Holdings  Affiliates")  shall be subject to certain
restrictions,  as more fully  described  below.  Persons who may be deemed to be
affiliates of Holdings or Omnicom generally include individuals or entities that
control, are controlled by, or are under common control with, such party and may
include  certain  officers  and  directors  of such  party as well as  principal
stockholders  of such party.  The Acquisition  Agreement  provides that Holdings
will furnish  Omnicom with a list  identifying all persons who may be considered
to be Holdings  Affiliates,  and gives Omnicom the right to review such list and
require  changes.  Holdings is required to use its best efforts to cause each of
the Holdings  Affiliates to execute a written agreement to comply fully with the
restrictions described below.

     Federal  Securities  Laws.  Shares of  Omnicom  Common  Stock  received  by
Holdings   Affiliates  may  be  resold  by  such  Holdings  Affiliates  only  in
transactions  permitted by the resale  provisions of Rule 145 promulgated  under
the Securities Act or as otherwise permitted under the Securities Act.

     Pooling-of-Interests  Rules.  In  order  to  satisfy  a  condition  of  the
pooling-of-interests  rules  as the  accounting  treatment  to be  accorded  the
Acquisition,  Holdings  Affiliates  may  not  sell,  assign,  transfer,  convey,
encumber or dispose of, directly or indirectly,  or otherwise  reduce their risk
relative to, any shares of Omnicom Common Stock until the publication by Omnicom
of its financial  results  covering a period of at least thirty days of combined
operations  of Omnicom and the  Businesses  after the Closing  Date (except that
this  restriction  will  lapse no later  than  October  30,  1995 as long as the
Closing of the  Acquisition  has occurred on or prior to August 31, 1995).  This
prohibition precludes the use of "hedging" techniques during this period.

                             Stock Exchange Listing

     It is a  condition  to the  Acquisition  that the shares of Omnicom  Common
Stock required to be issued in connection with the Acquisition be authorized for
listing on the NYSE, subject to official notice of issuance.  An application has
been filed for listing such Omnicom Common Stock on the NYSE.

                             No Dissenters' Rights

     Holders  of  Holdings  Common  Stock  are not  entitled  to any  rights  of
dissenting shareholders under Delaware law in connection with the Transactions.

                           THE ACQUISITION AGREEMENT

     (The  following is a brief  summary of the  Acquisition  Agreement  and the
related Escrow  Agreement.  Copies of the  Acquisition  Agreement and the Escrow
Agreement  are filed as Exhibits  to the  Registration  Statement  of which this
Prospectus/Information  Statement  forms a part and are  incorporated  herein by
reference.  This  summary is  qualified  in its  entirety  by  reference  to the
Acquisition Agreement and the Escrow Agreement.)


                                The Acquisition
General

     Omnicom,  TBWA,  Holdings  and  Advertising  entered  into the  Acquisition
Agreement  on May 11,  1995.  It  provides  for TBWA to  acquire  the  assets of
Holdings and  Advertising  other than (a) their  respective  corporate seals and
minute books,  (b) the issued and  outstanding  capital stock of Advertising and
Chiat/Day Direct Marketing, Inc. and any other subsidiary which is inactive, has
no  assets or is in the  process  of  liquidation,  (c) the  rights of  Holdings
arising under the Advertising Stock Sale Agreement,  other than the right to the
cash  acquisition  price  thereunder  to the extent  reflected  in the books and
records of Holdings,  and (d) the rights of  Advertising  in and to the National
Car Suit (the  value of which  will be  obtained  by TBWA  through  the right to
receive the cash acquisition  price receivable under the Advertising  Stock Sale
Agreement),  in exchange for the payment of the acquisition  price as more fully
described  below and the  assumption  by TBWA of  liabilities  of  Holdings  and
Advertising  relating to the Businesses  (certain  non-operating  liabilities of
Holdings and  Advertising are not to be assumed by TBWA pursuant to the terms of
the Acquisition Agreement).

Determination of Acquisition Price

     Subject to the potential  adjustment  described  below in "The  Acquisition
Agreement--The    Acquisition--Renegotiation    of   Acquisition   Price",   the
consideration payable by TBWA for the Businesses will be determined as follows:

          (a) TBWA will pay  Holdings  shares of Omnicom  Common Stock having an
     aggregate Market Value of (x) if the Closing is held on or prior to October
     31, 1995, (i) $11,180,563 plus (ii) an amount equal to $2,418 multiplied by
     the number of days in the period  commencing on the Closing Date and ending
     on October 31, 1995,  or (y) if the Closing Date is held after  October 31,
     1995 and on or prior to December 31, 1995,  (iii)  $11,930,880 plus (iv) an
     amount  equal to $2,418  multiplied  by the  number  of days in the  period
     commencing  on the Closing Date and ending on December  31,  1995.  Of this
     Omnicom  Common  Stock,  the  Contributed  Stock (being  shares having such
     Market Value as may be necessary to insure the  satisfaction of obligations
     of Holdings and  Advertising to the  Rightsholders)  will be contributed to
     Advertising for the benefit of the Rightsholders.

          (b) TBWA will pay Advertising shares of Omnicom Common Stock having an
     aggregate Market Value of $14,000,000.

     The "Market Value" of the shares of Omnicom Common Stock will be determined
by the average of the closing  prices per share of Omnicom Common Stock reported
on the New York Stock Exchange for the 20 consecutive  trading days ending three
business days immediately prior to the Closing Date.  Omnicom has agreed that it
will not, and will not permit TBWA or any of its other subsidiaries to, purchase
any  Omnicom  Common  Stock  (whether  pursuant  to  open-market   purchases  or
otherwise) during the period during which the Market Value is calculated.

     The shares of Omnicom Common Stock  received as  acquisition  price will be
allocated  on a pro rata basis to the  Holdings  Stockholders  after  allocating
sufficient shares to satisfy  Holdings' and Advertising's  obligations under the
EPU and EAR Plans.  Accordingly,  such  shares of Omnicom  Common  Stock will be
distributed to the Holdings  Stockholders and the  Rightsholders as described in
"The  Acquisition   Agreement--The   Acquisition  --Payment  of  Obligations  to
Rightsholders"  and  "The  Plan  of  Liquidation--Liquidating  Distributions  to
Holdings Stockholders" and "--Liquidating Distributions to Rightsholders".

Renegotiation of Acquisition Price

      In the event that on the scheduled Closing Date the "Annualized  Revenues"
of Holdings and its subsidiaries exceeds $100,000,000,  and the EBIT of Holdings
for  its  1995  Fiscal  Year  exceeds  or  is  reasonably   expected  to  exceed
$17,200,000,  then Omnicom, TBWA, Holdings and Advertising have agreed that each
would  negotiate  in good  faith  whether  or not  there  should  be an  upwards
adjustment to the acquisition  price. If agreement is reached to so increase the
acquisition  price,  the  Acquisition  Agreement and related  documents would be
amended to the extent  necessary to reflect this  adjustment.  If the parties do
not  agree on such an  increase,  Holdings  would  have  the  option  to  either
terminate the Acquisition  Agreement or proceed with the Closing at the original
acquisition price.

     "Annualized Revenues" has been defined in the Acquisition Agreement to mean
the  commissions and fees of Holdings and its  subsidiaries  for the fiscal year
commencing  November 1, 1994 and ending  October 31,  1995  (forecasted,  to the
extent necessary) from those clients that were such on October 31, 1994 and from
new clients won since November 1, 1994,  annualized as if those clients had been
clients during the entire year. The  calculation  excludes  commissions and fees
earned from  clients  lost since  November 1, 1994 or expected to be lost in the
near future.

     Holdings does not currently  anticipate,  based on its existing clients and
their  specified  budgets,  that  Annualized  Revenues  or EBIT will  exceed the
renegotiation thresholds.

Closing Date

     The  Acquisition   Agreement  provides  that  the  Closing  Date  shall  be
determined  by Omnicom by notice  given to  Holdings  within five days after the
date of the  Special  Meeting.  The Closing  Date chosen by Omnicom  must not be
later  than  thirty  days  after its  giving of the  notice;  and each  party is
required to use its best efforts to close on or prior to August 31, 1995, except
that if the Closing  has not  occurred  by August 31,  1995,  then each party is
required  to use its  best  efforts  to close  as soon as is  practicable  after
October 31, 1995.  Notwithstanding these requirements,  the Closing Date will be
delayed  in the event of a dispute  as to  whether  Annualized  Revenues  exceed
$100,000,000  and/or EBIT  exceeds  $17,200,000,  or during the  pendency of any
renegotiation  of the acquisition  price,  pending final  determination  of such
matters.

Arrangements With Respect to Holdings Preferred Stock

   
      On July 10, 1995 (the "Preferred Stock Purchase Date"), the Trustee of the
Profit Sharing Plan, the sole record owner of the Holdings Preferred Stock, sold
to Holdings for a cash payment of  $14,081,773.93  (representing  the  aggregate
liquidation  preference  of such  Holdings  Preferred  Stock)  all the shares of
Holdings  Preferred Stock it owned,  pursuant to the terms of the Profit Sharing
Plan Purchase Agreement.

     Certain financial  arrangements were made in order to finance this purchase
of Holdings  Preferred  Stock.  On the Preferred  Stock Purchase  Date,  Omnicom
guaranteed  a loan to  Holdings  in the  principal  amount of  $15,100,000  (the
"Preferred Stock Purchase Loan"), the proceeds of which were applied by Holdings
to purchase the Holdings  Preferred  Stock  pursuant to the Profit  Sharing Plan
Purchase Agreement and to repay certain other indebtedness.  On the day prior to
the Closing Date,  TBWA shall lend  Holdings an amount equal to the  outstanding
balance of the Preferred Stock Purchase Loan (the "TBWA Loan"),  the proceeds of
which will be applied by Holdings to repay the Preferred Stock Purchase Loan.
    

     Holdings  is  in  the  process  of  obtaining  all  governmental  approvals
(including  approval by the  Internal  Revenue  Service) and of taking all other
action  necessary to terminate the Profit Sharing Plan effective on or about the
Closing Date under the Acquisition Agreement,  even though such approvals may be
obtained and such action taken on or after the Closing Date.  Amounts on deposit
in the  Profit  Sharing  Plan  will  then  be  distributed  to  participants  in
accordance with their respective interests in the Profit Sharing Plan.


                                       27
<PAGE>

Payment of Obligations to Rightsholders

   
     In 1993 and 1988, Holdings adopted the EAR Plan and EPU Plan, respectively,
and has issued awards under such Plans.  If the  employment of a participant  is
terminated for any reason, then under the terms of the EAR Plan such participant
shall  have  the  right,  but  not the  obligation  within  ninety  days of such
termination to cause Holdings or Advertising to, and under the EPU Plan Holdings
or Advertising shall,  redeem vested units for cash in each case at the net book
value of the phantom shares which are the subject of the awards as at the end of
the most recent fiscal  quarter.  However,  in the event of a liquidation,  with
respect to their priority,  each EAR and EPU shall be deemed equivalent in value
to one share of Holdings Common Stock and shall be treated in the same manner as
Holdings Common Stock.

     Therefore,  as is the  case  with  Holdings  Stockholders,  obligations  of
Holdings  and  Advertising  to  the   Rightsholders   will  be  settled  by  the
distribution to the  Rightsholders  of shares of Omnicom Common Stock. To ensure
that  Advertising  will be able to  satisfy  such  obligations,  Holdings  shall
contribute to Advertising the Contributed Stock, if any is required to meet such
obligations.
    

     This  Prospectus/Information  Statement is being furnished to Rightsholders
because the Rightsholders will receive shares of Omnicom Common Stock as payment
under  such  Plans,  subject to the same  terms and  conditions  as if they were
Holdings  Stockholders.  Accordingly,  on the  Distribution  Date (a)  shares of
Omnicom  Common  Stock  paid to  Advertising  under  the  Acquisition  Agreement
(including  the  Contributed  Stock)  will  be  subject  to the  indemnification
obligations of Holdings, such that (i) ten percent of such shares will be placed
in the General Escrow Fund under the Escrow Agreement and (ii) shares of Omnicom
Common Stock having an aggregate  Market Value equal to the  Rightsholders'  pro
rata share of  $1,700,000  will be placed in the  Special  Escrow Fund under the
Escrow  Agreement,  and (b) five  percent of the shares of Omnicom  Common Stock
paid to Advertising under the Acquisition  Agreement  (including the Contributed
Stock)  will  be  transferred  to the  Liquidating  Trust  Escrow  Fund  to fund
(together  on a pro rata basis with the Holdings  Stockholders)  the payment and
satisfaction  of any  obligations and liabilities of Holdings and Advertising as
shall  not have  been  assumed  by TBWA  under the  Acquisition  Agreement.  The
remainder of the shares of Omnicom  Common Stock paid to  Advertising  under the
Acquisition  Agreement  (including the Contributed Stock) will be distributed to
the Rightsholders. See "The Plan of Liquidation--The Liquidating Trust Escrow".

     It  is  a  condition  of  Closing  of  the   Acquisition   Agreement   that
Rightsholders  that hold in the aggregate at least 83% of the  outstanding  EARs
and EPUs on the Closing Date,  which group must include all  Rightsholders  that
are also Holdings  Stockholders,  shall have delivered to Holdings their written
Consent  Letters to the effect  that they will not raise any  objection  to this
treatment and  consenting  to the  appointment  of Holdings as their  collective
agent in connection with the administration of the Escrow Agreement.

   
     As of August 1, 1995,  directors and executive officers of Holdings held an
aggregate of 84.44% of the outstanding  awards under the EAR and EPU Plans as of
such date.  Each of such  directors  and  executive  officers  has  executed and
delivered  to  Holdings  his or her  Consent  Letter in respect of such  awards.
Accordingly, the above described condition of Closing has been satisfied.
    

The Escrow Agreement

     Holdings  on  behalf  of  itself  and  the   Holdings   Stockholders,   and
Advertising, on behalf of itself and the Rightsholders shall establish, pursuant
to the Escrow Agreement,  the General Escrow Fund by the deposit with the Escrow
Agent of  certificates  in negotiable  form duly endorsed in blank  representing
shares of Omnicom  Common  Stock  equal to ten  percent of the shares of Omnicom
Common Stock issued and delivered as part of the acquisition  price. The General
Escrow Fund will be segregated into two funds: the  Stockholders  General Escrow
Fund and the  Rightsholders  General Escrow Fund, based on the respective number
of shares of Omnicom Common Stock  contributed by Holdings and Advertising,  and
each Fund will satisfy its pro rata share of any  indemnification  payment based
on the number of shares of Omnicom Common Stock then on deposit in such Fund.


                                       28
<PAGE>

   
     Holdings  and  Advertising  will also  establish,  pursuant  to the  Escrow
Agreement,  the Special  Escrow  Fund,  by the deposit  with the Escrow Agent of
shares of Omnicom  Common Stock having an aggregate  Market Value of $1,700,000,
of which  approximately  $750,000 will be contributed by Holdings,  on behalf of
the Holdings  Stockholders,  and  approximately  $950,000 will be contributed by
Advertising,  on behalf of the Rightsholders.  The Special Escrow Fund will also
be  segregated  into two funds:  the  Stockholders  Special  Escrow Fund and the
Rightsholders Special Escrow Fund, each of which will satisfy its pro rata share
of any  indemnification  payment based on the number of shares of Omnicom Common
Stock  on  deposit  in such  Fund.  (For a  description  of the  indemnification
obligations of Holdings and the Holdings  Stockholders and the  Rightsholders to
Omnicom,  see "The  Acquisition  Agreement--Other  Terms and  Conditions  of the
Acquisition Agreement--Indemnification".)
    

     Pursuant  to the Escrow  Agreement,  Holdings,  on behalf of itself and the
Holdings   Stockholders,   and   Advertising,   on  behalf  of  itself  and  the
Rightsholders, shall grant to Omnicom a security interest in the Escrow Funds to
secure the performance of the indemnification  obligations of Holdings under the
Acquisition  Agreement and the  performance of its  obligations to Omnicom under
the Escrow Agreement.

     Pursuant  to the Escrow  Agreement,  Omnicom  and  Holdings  have agreed to
indemnify  and hold the Escrow Agent and its  directors,  officers and employees
harmless  from and against any and all costs,  charges,  damages and  attorney's
fees which the Escrow Agent in good faith may incur or suffer in connection with
or arising out of the Escrow Agreement. The fees and charges of the Escrow Agent
with  respect  to the  Escrow  Agreement  shall be shared  between  Omnicom  and
Holdings in accordance  with the Escrow  Agent's  customary fees as charged from
time to time.  The Escrow Agent may deduct any unpaid fees from the Escrow Funds
prior to the  Escrow  Agent's  distributing  any assets in  connection  with the
termination of the Escrow Funds.

     The  Liquidating  Trustees shall replace  Holdings as a party to the Escrow
Agreement following the creation and funding of the Liquidating Trust.

      The Escrow  Agreement  shall  automatically  terminate if and when all the
shares  of  Omnicom  Common  Stock  held in any  Escrow  Fund  shall  have  been
distributed  by the  Escrow  Agent in  accordance  with the terms of the  Escrow
Agreement.

     General  Escrow Fund.  The Escrow  Agreement  provides that wherever  there
shall be  delivered  to the  Escrow  Agent  either (i) a  certificate  signed by
Omnicom and Holdings,  or (ii) a certified copy of an arbitration award rendered
pursuant  to the  arbitration  proceedings  specified  in the  Escrow  Agreement
determining,  that an  indemnification  payment is due from the  General  Escrow
Funds to  Omnicom,  the Escrow  Agent  shall,  to the extent  that the shares of
Omnicom  Common  Stock  then on  deposit  in the  General  Escrow  Fund shall be
sufficient  for the purpose,  deliver to Omnicom the number of shares of Omnicom
Common Stock,  valued at the original Market Value, equal to the indemnification
payment.

     On the next business day following the earlier of (x) the first independent
audit report, if any, of TBWA and the Businesses  following the Closing Date, or
(y) one year from the  Closing  Date,  the  Escrow  Agent  shall  deliver to the
Liquidating Trust (on behalf of the Holdings  Stockholders) the remaining shares
of Omnicom Common Stock then on deposit in the Stockholders General Escrow Fund,
and to the Liquidating  Trust Escrow Fund (on behalf of the  Rightsholders)  the
remaining  shares of Omnicom  Common Stock then on deposit in the  Rightsholders
General  Escrow Fund; as reduced in each case by any amounts  necessary to cover
outstanding claims for indemnification.

     All dividends,  interest and other amounts  received with respect to shares
of Omnicom  Common Stock held in the General Escrow Fund shall be income for tax
purposes to Holdings (or the Holdings Stockholders  following the dissolution of
Holdings)  and the  Rightsholders,  shall be paid  directly  to the  Liquidating
Trustees  (on behalf of the  Holdings  Stockholders)  or the  Liquidating  Trust
Escrow Agent (on behalf of the Rightsholders), as the case may be, and shall not
constitute part of the General Escrow Fund.

     Special  Escrow Fund.  The Escrow  Agreement  provides that whenever  there
shall be  delivered  to the  Escrow  Agent  either (i) a  certificate  signed by
Omnicom and Holdings, or (ii) a certified copy of a final nonappealable judgment
of an  arbitration  award  rendered  pursuant  to  the  arbitration  proceedings
specified in the Escrow  Agreement  determining,  that a payment is due from the
Special  Escrow  Fund to Holdings or Omnicom,  the Escrow  Agent  shall,  to the
extent  that the shares of Omnicom  Common  Stock then on deposit in the Special
Escrow  Fund  shall be  sufficient  for the  purpose,  deliver to such party the
number of shares of Omnicom Common Stock,  valued at the original  Market Value,
equal to the payment.


                                       29

     Amounts will be due from the Special Escrow Fund when the collectibility of
the  Indemnified  Receivable  becomes  determined or, if earlier,  on the second
anniversary of the Closing Date under the Acquisition Agreement.  Therefore,  at
such  time,  if any,  as TBWA  recovers  the  payments  in respect of said asset
("Asset  Proceeds"),  it shall give notice to such effect to Holdings and to the
Escrow Agent,  together with an accounting of the costs and expenses incurred in
connection  with  recovering  any such  payments at any time after the Execution
Date of the Acquisition  Agreement  ("Asset  Costs").  TBWA shall be entitled to
receive payment from the Stockholders  Special Escrow Fund and the Rightsholders
Special Escrow Fund, pro rata in accordance with the number of shares of Omnicom
Common  Stock  then on  deposit  in each such  Fund,  in the amount of the Asset
Costs; the Liquidating Trustees (on behalf of the Holdings Stockholders) and the
Liquidating  Trust  Escrow  Agent  (on  behalf  of the  Rightsholders)  shall be
entitled to receive  payment from the  Stockholders  Special Escrow Fund and the
Rightsholders  Special  Escrow Fund,  pro rata in accordance  with the number of
shares  of  Omnicom  Common  Stock  then on  deposit  in each such  Fund,  in an
aggregate  amount equal to (i) the amount of the Asset  Proceeds,  less (ii) the
Asset Costs, less (iii) $250,000 if the final determination of the matter occurs
within one year from the Closing  Date,  or $300,000 if the matter is determined
thereafter;  TBWA  shall  then be  entitled  to  receive  the  balance,  if any,
remaining in the Special Escrow Fund.

     All dividends,  interest and other amounts  received with respect to shares
of Omnicom  Common Stock held in the Special Escrow Fund shall be income for tax
purposes to Holdings (or the Holdings Stockholders  following the dissolution of
Holdings)  and the  Rightsholders,  shall be paid  directly  to the  Liquidating
Trustees  (on behalf of the  Holdings  Stockholders)  or the  Liquidating  Trust
Escrow Agent (on behalf of the Rightsholders), as the case may be, and shall not
constitute part of the Special Escrow Fund.

The Deposit and Pledge Agreement

     Pursuant to the Deposit and Pledge Agreement, Holdings and Advertising will
deliver to the Deposit Agent all the shares of Omnicom  Common Stock received by
them on the Closing Date.

     On the Distribution  Date, the Deposit Agent will make the distributions of
such   shares  of   Omnicom   Common   Stock   described   under   "Summary--The
Acquisition--The  Acquisition" to the Liquidating  Trust, the Liquidating  Trust
Escrow Fund, the Holdings Stockholders and the Rightsholders.

     On  the  Distribution  Date,  the  Deposit  Agent  will  also  deposit  the
applicable  shares of Omnicom Common Stock into the Escrow Funds.  Prior to such
time, the  applicable  shares of Omnicom Common Stock will be held by the Escrow
Agent  as  security  for the  fulfillment  of the  obligation  of  Holdings  and
Advertising to deliver such shares into the Escrow Funds.

Employment Arrangements

      The Acquisition Agreement provides that TBWA or one of the other companies
operating  within  the TBWA  International  network  will  offer  employment  to
substantially  all  employees of Holdings  and its  subsidiaries  following  the
Closing of the  Acquisition;  and that such personnel who accept such employment
will be  employed  on  substantially  equivalent  terms and  conditions  as such
personnel  were  employed by Holdings or a subsidiary  immediately  prior to the
Closing Date. The  Acquisition  Agreement also provides for specific  employment
arrangements with certain key executives;  see "The  Transactions--Interests  of
Certain Persons in the Transactions".

     Pursuant to the Acquisition Agreement, Holdings has agreed that, during the
period  from the date of the  Acquisition  Agreement  until  the  Closing  Date,
Holdings and each of its subsidiaries  will, among other things:  (a) obtain all
government  approvals and other action necessary to terminate the Profit Sharing
Plan of  Holdings;  (b) not solicit,  initiate or  encourage  any other offer or

Acquisition  and  the  other   transactions   contemplated  by  the  Acquisition

                                       31
<PAGE>

Indemnification

     The Acquisition  Agreement  provides that Holdings shall indemnify and hold
harmless, and shall reimburse TBWA and its affiliates,  directors, officers, and
employees for all losses,  claims,  damages and  liabilities  (to the extent not
covered by insurance),  and all fees, costs and expenses  (including  reasonable
attorneys'  fees)  related  thereto  (together  referred  to herein as "Loss" or
"Losses"),  arising out of, based upon, or resulting  from (i) the inaccuracy or
breach of any  representation or warranty (other than that referred to in clause
(iv)  below)  of  Holdings  or  Advertising  or  any  covenant  of  Holdings  or
Advertising contained in or made pursuant to the Acquisition Agreement, (ii) the
breach of or failure by  Holdings or  Advertising  to perform or  discharge  its
obligations   under  the  Acquisition   Agreement  or  under  the   transactions
contemplated thereby, (iii) a claim or cause of action by a third party relating
to any  liability of Holdings or  Advertising  not assumed by TBWA,  or (iv) any
inaccuracy in or breach of a specified  representation  and warranty relating to
the Indemnified  Receivable.  Pursuant to the Acquisition  Agreement,  no Losses
arising  out of a  matter  referred  to in (i),  (ii) or  (iii)  above  shall be
reimbursed  to TBWA  until  such  time as all  Losses  arising  out of a  matter
referred to in (i) through  (iii) above  shall  exceed  $300,000,  in which case
Holdings  shall be liable for all Losses in excess of $300,000  (Losses  arising
out of the matter referred to in clause (iv) above shall be reimbursable without
regard to the $300,000 "cushion").  Losses arising out of matters referred to in
clauses (i)  through  (iii)  above  shall be  satisfied  only out of the General
Escrow  Fund and Losses  arising  out of the matter  referred  to in clause (iv)
above shall be  satisfied  only out of the Special  Escrow Fund.  The  aggregate
indemnity  obligation of Holdings as so determined  shall be satisfied  from the
Escrow Funds as provided in the Escrow  Agreement,  and neither Omnicom nor TBWA
nor any of their  affiliates  will have any recourse for the payment of any such
indemnity   obligations   against  Holdings  or  Advertising  (or  the  Holdings
Stockholders  or  Rightsholders),  nor will any of such  persons  be  personally
liable for any such indemnity obligations.  See "The Acquisition  Agreement--The
Acquisition--Escrows".  Indemnity  obligations  shall  be paid by  returning  to
Omnicom out of the  relevant  Escrow Fund the number of whole  shares of Omnicom
Common Stock,  valued at the original Market Value, equal to the Losses (subject
to the $300,000 "cushion," where applicable).

     The  obligation  of  Holdings to  indemnify  shall  terminate  and be of no
further  force  and  effect  on the  earlier  to  occur of (x) the date of first
independent audit report, if any, of the consolidated  financial results of TBWA
and the Businesses following the Closing Date, and (y) one year from the Closing
Date (the "Indemnity Period").  Upon the expiration of the Indemnity Period, all
such  representations,   warranties,  covenants  and  agreements  shall  expire,
terminate,  and be of no further force or effect, except that claims asserted in
writing against Holdings on or prior to such expiration shall survive until they
are decided and are final and binding upon TBWA and Holdings.  However,  in that
the collectibility of the Indemnified Receivable cannot reasonably be assured at
the present  time,  these  limitations  will not apply to the matter as to which
TBWA  is  entitled  to  be  indemnified   under  that  clause.   Instead,   this
indemnification  obligation  will  terminate  on the  earlier  of (i) the second
anniversary  of the  Closing  Date,  the date by which the  parties  expect such
collectibility  to have been finally  determined and (ii) the date on which such
collectibility shall in fact have been finally determined,  provided that claims
asserted in writing prior to such expiration  shall survive until they are final
and binding.

     See    "The    Acquisition    Agreement--The     Acquisition--The    Escrow
Agreement--General Escrow Fund" and "--Special Escrow Fund."

     Pursuant  to the  Acquisition  Agreement,  Omnicom and  Holdings  have also
agreed to  indemnify  the other,  including  its  directors,  officers,  agents,
"controlling persons" as defined by the Securities Act, and attorneys (and, with
respect to Holdings,  the Holdings  Stockholders and Rightsholders)  against any
liability, damage, cost, loss, or expense arising out of any untrue statement of
a material fact furnished by it for inclusion in the Registration  Statement, or
caused by any omission to furnish a material fact concerning it that is required
to be stated therein or that is necessary to make the statements furnished by it
not   misleading.   This   indemnification   obligation  is  separate  from  the
indemnification  obligation  of Holdings  to TBWA  discussed  above,  and is not
limited to amounts on deposit in the Escrow  Funds  under the Escrow  Agreement,
nor to the limited periods of survival.

Sale  Agreement,  the  amendment  of the  Holdings  Certificate  and the Plan of

pooling-of-interests  for accounting purposes; (ii) Advertising continuing to be

the  Businesses  (which  shall  include  TBWA  not  having  received  reasonable
assurances  and financial  data that (a) if the Closing is on or prior to August
31, 1995,  EBIT for the nine months  ended July 31, 1995 is at least  $7,500,000
and EBIT for the 1995 Fiscal Year is reasonably  expected to exceed $13,500,000;

Transactions--Interests of Certain Persons in the Transactions".

     Pursuant  to the terms of the  Acquisition  Agreement,  each of Omnicom and
Holdings is  entitled  to waive any of its  conditions  to  consummation  of the
Acquisition  to the extent that any such  condition is not  satisfied in full by
the other party, other than conditions  relating to the absence of any objection
by the SEC to Omnicom's  treatment of the Acquisition as a  pooling-of-interests
for  accounting  purposes and the approval of the  Transactions  by the Holdings
Stockholders.

Advertising  have made  certain  additional  agreements  with respect to periods

                                       33
<PAGE>

Termination

     The   Acquisition   Agreement  may  be  terminated  and  the   contemplated
Acquisition may be abandoned at any time prior to the Closing, whether before or
after approval by the Holdings Stockholders, (a) by mutual consent of the Boards
of Directors of Omnicom,  TBWA, Holdings and Advertising;  (b) by either Omnicom
and TBWA,  on the one hand, or Holdings and  Advertising,  on the other hand, if
there has been a breach of any representation,  warranty or covenant on the part
of the other party set forth in the  Acquisition  Agreement which breach has not
been cured within 30 days following  receipt by the breaching party of notice of
such breach, unless the breach of any such representation, warranty, or covenant
does not  materially  adversely  affect the business or assets of the  breaching
party or the ability of either party or parties to consummate  the  Acquisition;
(c) by the Board of Directors of Omnicom,  TBWA,  Holdings or  Advertising  if a
final  and  nonappealable  order,  decree  or  judgment  of any  court  or other
governmental  authority is issued which would enjoin the Acquisition;  or (d) by
either  Omnicom and TBWA or Holdings and  Advertising  if the Closing Date shall
not have occurred  prior to the close of business on December 31, 1995 or at any
time after October 31, 1995 if the  conditions  to such  parties'  obligation to
close shall have become incapable of being satisfied by December 31, 1995.

     In the event of any  termination  of the  Acquisition  Agreement  by either
Omnicom  and  TBWA  or by  Holdings  and  Advertising  as  provided  above,  the
Acquisition  Agreement  shall  become  void and there  will be no  liability  or
obligation  on the part of any party or its  respective  officers  or  directors
except that such  termination  does not preclude any action or claim for damages
to which any party is  otherwise  entitled  as a result of a breach by the other
party.

Amendment

     The  Acquisition  Agreement and the exhibits and  schedules  thereto may be
amended,  supplemented  or  qualified  by the parties  only by an  agreement  in
writing signed by all parties with due authorization.

                      THE ADVERTISING STOCK SALE AGREEMENT

     (A copy of the  Advertising  Stock Sale Agreement is filed as an Exhibit to
the Registration Statement of which this Prospectus/Information  Statement forms
a part and is incorporated herein by reference.  This summary of the Advertising
Stock  Sale  Agreement  is  qualified  in its  entirety  by  reference  to  such
agreement.)

   
     Pursuant to the Advertising  Stock Sale  Agreement,  as soon as practicable
after the  Distribution  Date,  Adelaide  Horton  (together  with any  permitted
assignees) will purchase from Holdings all of the issued and outstanding  common
stock of Advertising.  At such time, the only asset which  Advertising  will own
will be its  rights,  through  its  ownership  of all of the  capital  stock  of
Chiat/Day Direct Marketing,  Inc., under the National Car Suit.  Pursuant to the
Advertising  Stock Sale  Agreement,  Holdings has agreed to indemnify Ms. Horton
and Advertising for any losses incurred in respect of liabilities of Advertising
not assumed by TBWA under the Acquisition Agreement. To the extent that Holdings
were unable to fully indemnify Ms. Horton and Advertising, any recovery from the
National Car Suit received by Advertising would be at risk.
    

                 PROPOSED AMENDMENT OF THE HOLDINGS CERTIFICATE

     The  Holdings  Certificate  sets forth the  corporate  name of  Holdings as
"Chiat/Day   Holdings,   Inc."  Following  the  Closing  under  the  Acquisition
Agreement, TBWA will own all rights in and to the "Chiat/Day" name, and Holdings
has agreed that immediately following the Closing thereunder it would change its
corporate  name to a name  not  including  the  "Chiat/Day"  designation  or any
variation thereof.  Under the proposed amendment  Holdings' name will be changed
to "CDH Corporation".  Pursuant to the Acquisition  Agreement,  Advertising will
also  change  its  corporate  name  to a  name  not  including  the  "Chiat/Day"
designation or any variation thereof,  and each of Holdings and Advertising will
cause its inactive  subsidiaries  which are not being acquired by TBWA under the
Acquisition  Agreement,  to  effect a  similar  change  to its  corporate  name.
Advertising  intends to change its name to "CDAD  Corporation" . Approval by the
Holdings  Stockholders  of  this  amendment  to the  Holdings  Certificate  is a
condition of Omnicom's and TBWA's obligation to consummate the Acquisition under
the Acquisition Agreement.

                            THE PLAN OF LIQUIDATION

     (Copies of the Plan of Liquidation, the Liquidating Trust Agreement and the
Liquidating  Trust Escrow  Agreement  are filed as Exhibits to the  Registration
Statement of which this  Prospectus/Information  Statement  forms a part and are
incorporated herein by reference.  This summary of the Plan of Liquidation,  the
Liquidating  Trust  Agreement  and the  Liquidating  Trust  Escrow  Agreement is
qualified in its entirety by reference to such agreements.)

                                    General

     The Plan of Liquidation  provides that,  upon  consummation  of the Closing
under the  Acquisition  Agreement,  Holdings  will be dissolved  pursuant to the
provisions of the DGCL.  Following the  procedures  prescribed in the DGCL,  the
Board of  Directors  of Holdings  will file with the  Secretary  of State of the
State  of  Delaware  a  Certificate  of  Dissolution,  thereby  terminating  the
corporate existence of Holdings.  Thomas Patty and David Wiener, the Liquidating
Trustees of the Liquidating Trust established  pursuant to the Liquidating Trust
Agreement will,  however,  function with authority to wind up Holdings' affairs,
pay,  satisfy and discharge  certain  liabilities and obligations not assumed by
TBWA  under  the   Acquisition   Agreement,   and  distribute  to  the  Holdings
Stockholders all of the remaining assets of Holdings.

     The distribution of the shares of Omnicom Common Stock will not occur until
the  Distribution  Date.  Assuming the Closing  occurs on August 31,  1995,  the
earliest that the Distribution  Date would occur is October 26, 1995. During the
period from the Closing Date until the Distribution Date, Holdings  Stockholders
and Rightsholders  will bear the risk of fluctuations in the market price of the
Omnicom Common Stock.

     The Liquidating Trust, after the Acquisition and the distributions to occur
on the  Distribution  Date,  shall  hold all the  remaining  assets of  Holdings
(except to the extent Holdings  distributes any such assets directly to Holdings
Stockholders),  including  the right to receive any assets  remaining  after the
termination  of the Escrow  Agreement.  If any assets remain in the  Liquidating
Trust after all claims, charges,  liabilities and obligations of the Liquidating
Trust  have  been  paid  or  discharged,   the  Liquidating  Trustees  will,  as
expeditiously as is practicable, distribute such assets to the former holders of
Holdings Common Stock on a pro rata basis according to their interests.

     All of the  directors  and  officers  of  Holdings  who are  also  Holdings
Stockholders have indicated that they intend to vote for the Plan of Liquidation
in their capacity as Holdings  Stockholders.  In order to effectuate the Plan of
Liquidation,  Holdings will give notice to all known  creditors,  if any,  after
giving  effect  to  the  assumption  of  liabilities  by  TBWA  pursuant  to the
Acquisition  Agreement,  and will pay or make  adequate  provision for any Trust
Liabilities.   It  is  intended  that  the   consummation  of  the  transactions
contemplated by the Acquisition  Agreement,  followed by the distribution to the
Holdings Stockholders in complete liquidation of Holdings, will not give rise to
dissenter's rights in favor of Holdings Stockholders under Delaware law.

               Liquidating Distribution to Holdings Stockholders

     Pursuant to the Plan of Liquidation,  on the  Distribution  Date,  Holdings
Stockholders  will receive a distribution  of the shares of Omnicom Common Stock
paid by TBWA to Holdings as acquisition  price under the  Acquisition  Agreement
(exclusive of the Contributed Stock), as reduced by (i) the five percent of such
shares  which will be deposited  by Holdings on the  Distribution  Date into the
Liquidating Trust on behalf of the Holdings  Stockholders and (ii) the shares of
Omnicom  Common  Stock used to fund on the  Distribution  Date the  Stockholders
General  Escrow Fund and the  Stockholders  Special Escrow Fund under the Escrow
Agreement.

   
     Based on an estimated  total  acquisition  price of  $25,328,061  (see "The
Acquisition  Agreement--The  Acquisition--Determination  of Acquisition Price"),
each holder of Holdings Common Stock will be entitled to receive in such initial
distribution, per share of Holdings Common Stock, shares of Omnicom Common Stock
with a value  (determined  in  accordance  with  the  terms  of the  Acquisition
Agreement)  equal to  $0.178.  The  remaining  shares of  Omnicom  Common  Stock
received by Holdings will be used to fund the Liquidating  Trust,  which will be
responsible for the Holdings  Stockholders' taxes and the expenses of winding up
the affairs of Holdings, as well as possible contingent liabilities, and to fund
the Stockholders  General Escrow Fund and the Stockholders  Special Escrow Fund.
Based upon current estimates of taxes and expenses,  if there were no claims for
indemnification or other contingent liabilities, each Holdings Stockholder would
be entitled to receive upon the release of such funds from the Liquidating Trust
    


                                       35

and such  escrows  shares of Omnicom  Common Stock with a value  (determined  in
accordance with the terms of the Acquisition  Agreement)  equal to approximately
$0.037, for a total per share value of approximately  $0.215.  Since the amounts
held in such  escrows  and such  trust  are  subject  to claims  in  respect  of
contingent  liabilities,  there can be no  assurances  that amounts held therein
will in fact be distributed to the Holdings Stockholders.
    

                   Liquidating Distribution to Rightsholders

     On  the  Distribution   Date,  the   Rightsholders   will  also  receive  a
distribution  of Omnicom  Common Stock from  Advertising.  See "The  Acquisition
Agreement--The Acquisition--Payment of Obligations to Rightsholders". The shares
of Omnicom Common Stock  available for such  distribution  will be the shares of
Omnicom Common Stock paid by TBWA to Advertising as acquisition  price under the
Acquisition  Agreement  (inclusive of the Contributed  Stock), as reduced by (i)
the five percent of such shares which will be  deposited by  Advertising  on the
Distribution  Date  into the  Liquidating  Trust  Escrow  Fund on  behalf of the
Rightsholders  and (ii) the shares of Omnicom  Common  Stock used to fund on the
Distribution  Date the  Rightsholders  General Escrow Fund and the Rightsholders
Special Escrow Fund under the Escrow Agreement.

   
     Based on an estimated  total  acquisition  price of  $25,328,061  (see "The
Acquisition  Agreement--The  Acquisition--Determination  of Acquisition Price"),
each  Rightsholder  (whether an EPU holder or an EAR holder) will be entitled to
receive in such  distribution,  per EPU or EAR,  shares of Omnicom  Common Stock
with a value  (determined  in  accordance  with  the  terms  of the  Acquisition
Agreement)  equal to  $0.178.  The  remaining  shares of  Omnicom  Common  Stock
received by Advertising will be used to fund the Liquidating  Trust Escrow Fund,
which will be responsible for the Rightsholders' share of taxes and the expenses
of  winding  up  the  affairs  of  Holdings,  as  well  as  possible  contingent
liabilities,  and  to  fund  the  Rightsholders  General  Escrow  Fund  and  the
Rightsholders  Special  Escrow Fund.  Based upon current  estimates of taxes and
expenses,  if there  were no  claims  for  indemnification  or other  contingent
liabilities, each Rightsholder would be entitled to receive, upon the release of
such funds from such escrows,  shares of Omnicom  Common Stock with an aggregate
value  (determined in accordance  with the terms of the  Acquisition  Agreement)
equal to  approximately  $0.037,  for a total  per unit  value of  approximately
$0.215.  Since the amounts held in such escrows are subject to claims in respect
of contingent liabilities,  there can be no assurances that amounts held therein
will in fact be distributed to the Rightsholders.
    

                               Fractional Shares

     If any  of the  foregoing  distributions  does  not  result  in a  Holdings
Stockholder  or  Rightsholder  being  entitled  to a whole  number  of shares of
Omnicom Common Stock,  the Holdings  Stockholder or Rightsholder  will receive a
cash payment in lieu of any entitlement to a fractional  share of Omnicom Common
Stock from the proceeds of a sale on the NYSE by Holdings or Advertising (as the
case may be) of a sufficient  number of shares of Omnicom Common Stock to settle
the  aggregate  amount of  fractional  share  distribution  entitlements  of all
similarly  situated  Holdings  Stockholders and  Rightsholders.  As a result, no
fractional  shares of Omnicom Common Stock will be distributed under the Plan of
Liquidation.

                       Operation of the Liquidating Trust

     Following the dissolution of Holdings and the completion of the liquidating
distributions  described above, each share of Holdings Common Stock,  regardless
of class,  shall have an equal  interest in the  Liquidating  Trust.  After such
time, the Liquidating Trustees will, on behalf of the Holdings Stockholders, (i)
receive any additional liquidating  distributions from Holdings, (ii) act as the
agent of the Holdings  Stockholders in connection with the administration of the
Escrow Agreement and the Liquidating  Trust Escrow  Agreement,  (iii) respond to
the assertion of any and all claims of  indemnification  by TBWA pursuant to the
terms of the  Acquisition  Agreement and the Escrow  Agreement,  (iv) pursue any
claims which  Holdings may have against the Special Escrow Fund and (v) complete
the winding up of the affairs of Holdings and the payment of certain liabilities
not  assumed by TBWA under the  Acquisition  Agreement  out of the assets of the
Liquidating Trust.

     As  described   above  under   "--Liquidating   Distribution   to  Holdings
Stockholders",  five percent of the shares of Omnicom  Common Stock  received by
Holdings  as part of the  acquisition  price  under  the  Acquisition  Agreement
(exclusive of the Contributed Stock) will be deposited in the Liquidating Trust,
on behalf of the Holdings  Stockholders,  for the  satisfaction of the following


                                       36
<PAGE>

liabilities (collectively,  "Trust Liabilities") of Holdings (in each case other
than the liabilities assumed by TBWA pursuant to the Acquisition Agreement): (i)
all claims and obligations,  including all contingent,  conditional or unmatured
contractual  claims,  known to Holdings or the  Liquidating  Trustees,  (ii) any
claim  which is the  subject of a pending  action,  suit or  proceeding  against
Holdings  and  (iii)  claims  which,  based on facts  known to  Holdings  or the
Liquidating  Trustees,  are likely to arise or become  known to  Holdings or the
Liquidating  Trustees within ten years.  The obligation of Holdings to indemnify
TBWA and  Advertising  for  losses  arising  out of  retained  liabilities  will
constitute a Trust  Liability.  See "The Advertising  Stock Sale Agreement".  In
addition,  Trust  Liabilities  will  include the costs and  expenses  payable by
Holdings in respect of (i) the Escrow  Agent's fees under the Escrow  Agreement,
(ii)  maintaining  insurance to cover  indemnification  obligations  of Holdings
under the  Holdings  Certificate  and the  Liquidating  Trust  Agreement  to its
directors,  officers and agents  (including the Liquidating  Trustees) and (iii)
certain legal and other  professional  fees in connection with the  liquidation,
the  establishment  of the  trust,  final tax  returns  and  other  post-Closing
transactions and matters. As described more fully below under "--The Liquidating
Trust Escrow", the Liquidating Trustees shall be reimbursed from the Liquidating
Trust Escrow Fund for the  Rightsholders'  share of any such Trust  Liabilities.
The  Liquidating  Trust will also  receive  from time to time,  on behalf of the
Holdings   Stockholders,   distributions   of  Omnicom  Common  Stock  from  the
Stockholders  General  Escrow  Fund and the  Stockholders  Special  Escrow  Fund
maintained pursuant to the Escrow Agreement. See "The Acquisition Agreement--The
Acquisition--The Escrow Agreement". Pursuant to the Liquidating Trust Agreement,
the  Liquidating  Trustees will promptly sell any shares of Omnicom Common Stock
received by them and retain the net cash  proceeds as the  property  (the "Trust
Property") of the Liquidating Trust.

     Pursuant to the Liquidating Trust Agreement, the Liquidating Trustees shall
invest and reinvest the Trust  Property and shall  maintain any income earned on
such Trust Property  ("Trust  Income")  separately from the Trust Property.  The
Trust  Income will  include  any cash and other  taxable  dividends  paid to the
Liquidating  Trustees,  on behalf of the  Holdings  Stockholders,  in respect of
Omnicom Common Stock on deposit in the Stockholders  General Escrow Fund and the
Stockholders   Special   Escrow  Fund.  See  "The   Acquisition   Agreement--The
Acquisition--The Escrow Agreement".  All Trust Income will be distributed by the
Liquidating  Trustees at the end of each fiscal  quarter to the former  Holdings
Stockholders, pro rata in accordance with their interests.

     The  Liquidating  Trustees  shall  distribute  Trust Property at least once
annually to the former Holdings Stockholders,  pro rata in accordance with their
interests,  provided that no  distribution  shall be made without  satisfying or
adequately providing for (i) a reserve for all remaining Trust Liabilities, (ii)
a reserve for Trustee expenses and (iii) a reserve for payments owing to missing
beneficiaries.

     The  termination  of the  Liquidating  Trust will occur on the later of (i)
three years and six months from the date the Liquidating Trust is established or
upon payment to the former  Holdings  Stockholders  of all of the Trust Property
and Trust Income,  whichever is earlier, and (ii) the date of termination of the
Escrow  Agreement,  provided  that the  Liquidating  Trust shall  continue for a
reasonable  period for the limited  purpose of discharging  any remaining  Trust
Liabilities.

                          The Liquidating Trust Escrow

   
     As    described    above    under    "The    Acquisition     Agreement--The
Acquisition--Payment of Obligations to Rightsholders" five percent of the shares
of Omnicom Common Stock received by Advertising as part of the acquisition price
under the  Acquisition  Agreement  (including  five  percent of the  Contributed
Stock) will be deposited in the separate  Liquidating  Trust Escrow Fund created
by the  escrow  agreement  (the  "Liquidating  Trust  Escrow  Agreement")  among
Holdings  (or,  after the creation  and funding of the  Liquidating  Trust,  the
Liquidating  Trust),  Advertising  and David C.  Wiener,  as escrow  agent  (the
"Liquidating  Trust  Escrow  Agent"),  on behalf of the  Rightsholders,  for the
satisfaction of the Rightsholders'  share of Trust Liabilities.  The Liquidating
Trust  Escrow  Agent  may also  receive  from  time to time,  on  behalf  of the
Rightsholders,  distributions  of Omnicom  Common  Stock from the  Rightsholders
General  Escrow  Fund  and the  Rightsholders  Special  Escrow  Fund  maintained
pursuant  to  the  Escrow   Agreement.   See  "The  Acquisition   Agreement--The
Acquisition--The  Escrow  Agreement".  Pursuant to the Liquidating  Trust Escrow
Agreement,  the Liquidating  Trust Escrow Agent will promptly sell any shares of
Omnicom  Common  Stock  received  by it and retain the net cash  proceeds in the
Liquidating Trust Escrow Fund.
    


                                       37
<PAGE>

     Pursuant to the Liquidating Trust Escrow  Agreement,  the Liquidating Trust
Escrow Agent shall  invest and reinvest the funds on deposit in the  Liquidating
Trust Escrow Fund (any income earned in respect of such funds,  the "Liquidating
Trust Escrow Income"). The Liquidating Trust Escrow Income will include any cash
and other taxable  dividends  paid to the  Liquidating  Trust Escrow  Agent,  on
behalf of the  Rightsholders,  in respect of Omnicom  Common Stock on deposit in
the Rightsholders General Escrow Fund and the Rightsholders Special Escrow Fund.
All Liquidating Trust Escrow Income will be distributed by the Liquidating Trust
Escrow Agent at the end of each fiscal quarter to the former Rightsholders,  pro
rata in accordance with their interests.

     The  Liquidating  Trust Escrow Agent will reimburse the  Liquidating  Trust
from  the  Liquidating  Trust  Escrow  Fund,  upon  proper  request  made by the
Liquidating  Trustees,  for the Rightsholders'  proportionate  share of payments
made  by  the  Liquidating   Trust  in  respect  of  Trust   Liabilities.   Such
proportionate  share shall be equal to (x) the total  amount of the payment made
by the Liquidating Trustee multiplied by (y) a fraction,  the numerator of which
equals the total amount of funds then on deposit in the Liquidating Trust Escrow
Fund and the  denominator  of which equals (1) the numerator plus (2) the amount
of Trust Property then on deposit in the Liquidating Trust.

     Upon each distribution by the Liquidating  Trustee of Trust Property to the
Stockholders pursuant to the Liquidating Trust Agreement,  the Liquidating Trust
Escrow Agent shall distribute to the Rightsholders,  pro rata in accordance with
their interests,  the same percentage of the Liquidating Trust Escrow Fund as is
being distributed to the Holdings Stockholders from the Liquidating Trust.

     The  Liquidating   Trust  Escrow  Agent  will  act  as  the  agent  of  the
Rightsholders for purposes of the administration of the Liquidating Trust Escrow
Agreement.  The  Liquidating  Trust Escrow Agent will also serve as a trustee of
the Liquidating Trust.

                        FEDERAL INCOME TAX CONSEQUENCES
                             OF THE SALES OF ASSETS
                        AND DISSOLUTION AND LIQUIDATION

   
     The  following  discussion  summarizes  the U.S.  income  tax  consequences
associated  with the  Transactions  under the Internal  Revenue Code of 1986, as
amended  (the  "Code").  The  discussion   summarizes  the  federal  income  tax
consequences  that are material to the Holdings  Stockholders and  Rightsholders
(each, a "Holder") in general,  but it does not describe all of the consequences
that might be relevant to a particular  Holder in light of that Holder's own tax
situation.  Because the following  discussion  does not describe all potentially
relevant  tax  considerations,  each  Holder  should  consult his or her own tax
advisor  regarding the tax  consequences of the  Transactions in light of his or
her own tax  situation.  In  particular,  the  following  discussion  may not be
complete  or  applicable  in its  entirety  with  respect to Holders who are not
individuals,  who are dealers in  securities,  or who  acquired  their  Holdings
Common Stock through employee stock option programs.
    

                                 Corporate Tax

     Holdings  believes that although the asset sales by it and  Advertising and
the  Advertising  Stock Sale are taxable  transactions,  they will not result in
significant  federal  income tax  liability  being  incurred by  Holdings.  This
conclusion  is based on a number of  positions  taken or to be taken by Holdings
which  might be subject  to IRS  challenge.  To the extent  that the IRS were to
successfully  challenge  any  of  Holdings'  positions,   amounts  held  in  the
Liquidating Trust and the Liquidating Trust Escrow Fund would be used to pay the
ensuing tax  liability.  Accordingly,  no assurance can be given that any of the
portions held in the  Liquidating  Trust will be ultimately  distributed  to the
Holdings  Stockholders or that funds held in the  Liquidating  Trust Escrow Fund
will be ultimately  distributed to the  Rightsholders.  To the extent that funds
available from these sources were  inadequate to satisfy amounts due to the IRS,
the IRS could seek  payment  from  Holdings  Stockholders  to the extent of such
unsatisfied   liability  up  to  the  amounts   distributed   to  such  Holdings
Stockholders.

                                   Holder Tax

     The following summary applies only to Holders who are United States persons
for federal income tax purposes and except as specifically described below, does
not apply to Holders who are not U.S. persons.

Holders of Class A Common Stock and Mojo B Common Stock

     For federal income tax purposes,  holders of Class A Common Stock ("Class A
Stockholders")  and Mojo B Common Stock ("Mojo B  Stockholders")  will recognize
gain or loss as a result of the Transactions equal to the difference between the
sum of (i) the fair market value of all of the Omnicom shares received  (whether
distributed or placed in the Liquidating  Trust or the  Stockholders  General or
Special  Escrow Funds) plus (ii) the cash received in respect of any  fractional
shares,  and their  adjusted  basis in the Class A Common Stock or Mojo B Common
Stock.  Class A Stockholders  and Mojo B Stockholders who have held their shares
for over one year at the time of the transaction will be subject to tax at rates
up to the 28% maximum rate currently  applicable to long-term  capital gain. The
basis in the shares of Omnicom Common Stock received will be equal to their fair
market value on the  Distribution  Date and the holding period for the shares of
Omnicom  Common Stock will  commence on the date of the  distribution.  Provided
that the  Liquidating  Trust is  classified  as a trust for  federal  income tax
purposes  (see  discussion  below),  if  amounts  in the  Liquidating  Trust are
subsequently  used to pay  creditors (or payments are made to Omnicom out of the
Stockholders  General or Special Escrow Funds),  Class A Stockholders and Mojo B
Stockholders  should be entitled to a capital loss in the year such payments are
made. If the amount of payments made to creditors  that are allocable to a Class
A  Stockholder  or Mojo B  Stockholder  are in excess  of  $3,000  and the other
requirements  of section 1341 of the Code are met,  such  shareholder  should be
able to  compute  his or her  federal  income  tax  liability  for the year such
payments  are made  under the  provisions  of  section  1341 of the Code.  Under
section 1341 of the Code, a shareholder's  federal income tax liability would be
the lesser of the tax liabilities as computed under two alternative  computation
methods.  Under the first method,  the shareholder  would compute his or her tax
liability by taking a regular  capital loss in the year that  payments are made.
Under the second method, the shareholder would decrease his or her tax liability
in the year of payment by the amount of tax liability  that was generated by the
prior inclusion.  The tax return for the year of inclusion would not be reopened
under either  computation  method. No additional federal income tax consequences
will occur when amounts are distributed from the Liquidating  Trust to a Class A
Stockholder or a Mojo B Stockholder.

     With respect to a Class A Stockholder's  or Mojo B Stockholder's  shares of
Omnicom  Common  Stock  that  are  placed  in  the  Liquidating   Trust  or  the
Stockholders  General  or  Special  Escrow  Funds,  in the event the  shares are
disposed  of by the  Liquidating  Trust or the  Stockholders  General or Special
Escrow Funds,  any difference in the value of the shares of Omnicom Common Stock
between the date of distribution  and the date disposed of by Liquidating  Trust
or such Escrow Funds will be treated as long-term or short-term  capital gain or
loss by such Holder, depending on the holding period. Such Holder's share of any
other income  (including  dividends paid on the Omnicom  Common Stock),  gain or
loss realized by the Liquidating  Trust or the  Stockholders  General or Special
Escrow Funds will be recognized by such Holder  (whether or not  distributed) in
computing his or her federal income tax.

Holders of Class B Common Stock

     Holders of Class B Common Stock (other than holders of Mojo B Common Stock)
("Class  B  Stockholders")  will  recognize  compensation  income on the date of
distribution  of  shares  of  Omnicom  Common  Stock  pursuant  to the  Plan  of
Liquidation, equal to the excess of the sum of (i) the then fair market value of
the shares of Omnicom Common Stock (including the value of any amount to be held
in the Liquidating  Trust or the  Stockholders  General or Special Escrow Funds)
plus (ii) the cash received in respect of any fractional shares, over the sum of
(a) the amount they paid for their Class B Common Stock, and (b) the amount,  if
any, of ordinary  income  which they have  previously  recognized  in respect of
their Class B Common Stock. The Holder's holding period for his or her shares of
Omnicom Common Stock will commence on the date of distribution  and the basis of
the shares of Omnicom  Common Stock will be the fair market value on the date of
such distribution.

     With respect to a Class B Stockholder's shares of Omnicom Common Stock that
are  placed in the  Liquidating  Trust or the  Stockholders  General  or Special
Escrow Funds, in the event the shares are disposed of by the  Liquidating  Trust
or such  Escrow  Funds,  any  difference  in the value of the  shares of Omnicom


                                       39
<PAGE>

Common Stock  between the date of  distribution  and the date disposed of by the
Liquidating  Trust  or  such  Escrow  Funds  will be  treated  as  long-term  or
short-term capital gain or loss by such Holder, depending on the holding period.
Such Holder's share of any other income (including dividends paid on the Omnicom
Common Stock),  gains or losses realized by the Liquidating Trust or such Escrow
Funds will be recognized  by such Holder in computing his or her federal  income
taxes.

     In addition,  to the extent that any amount placed in the Liquidating Trust
or the Stockholders General or Special Escrow Funds is subsequently  utilized to
discharge an obligation of Holdings,  the affected Class B Stockholder should be
entitled to a federal  income tax  deduction,  in the year of such  expenditure,
equal to the  amount  of such  expenditure  previously  included  in the Class B
Stockholder's  income.  If the  amount of the  deduction  exceeds  $3,000,  such
deduction may qualify for treatment  under the  provisions of Code section 1341,
previously  described above. No additional  federal income tax consequences will
occur when amounts are  distributed  from the  Liquidating  Trust to the Class B
Stockholder.

Tax on Holders of EPUs and EARs

     Rightsholders  will recognize  compensation  income equal to the sum of (i)
the fair  market  value of the shares of  Omnicom  Common  Stock  which they are
entitled to receive in the  liquidation  of  Holdings,  on the date such Omnicom
Common Stock is either distributed or made available to them, plus (ii) the cash
received in respect of any  fractional  shares.  For this  purpose,  any Omnicom
Common Stock placed in the  Liquidating  Trust Escrow Fund or the  Rightsholders
General  or Special  Escrow  Funds on their  behalf is  treated  as having  been
distributed to them.

     With respect to a  Rightsholder's  shares of Omnicom  Common Stock that are
placed in the  Liquidating  Trust  Escrow Fund or the  Rightsholders  General or
Special  Escrow  Funds,  in the event the  shares are  disposed  of while in the
Liquidating  Trust Escrow Fund or the  Rightsholders  General or Special  Escrow
Funds,  any difference in the value of the Omnicom Common Stock between the date
of  distribution  and the date  disposed  of will be  treated  as  long-term  or
short-term  capital gain or loss by the  Rightsholder,  depending on the holding
period. The Rightsholder's  share of any other income (including  dividends paid
on the Omnicom Common Stock),  gains or losses realized by the Liquidating Trust
Escrow  Fund or the  Rightsholders  General  or  Special  Escrow  Funds  will be
recognized by the Rightsholder in computing his or her federal income tax.

     In addition,  to the extent that any amount placed in the Liquidating Trust
Escrow Fund or the Rightsholders General or Special Escrow Funds is subsequently
utilized to  discharge an  obligation  of  Holdings,  the affected  Rightsholder
should  be  entitled  to a federal  income  tax  deduction,  in the year of such
expenditure,  equal to the amount of such expenditure previously included in the
Rightsholder's  income.  If the amount of the  deduction  exceeds  $3,000,  such
deduction  may qualify for treatment  under the  provisions of Code section 1341
previously  discussed above. No additional  federal income tax consequences will
occur when amounts are distributed from the Liquidating Trust Escrow Fund or the
Rightsholders General or Special Escrow Funds to the Rightsholder.

Certain Consequences to Non-U.S. Holders

     A Holder who is not a U.S. person (a "Non-U.S.  Holder") will generally not
be subject to United States  federal income tax with respect to gain or ordinary
income  recognized  as a  result  of the  transaction  unless  (i)  the  gain is
effectively  connected  with a trade or business  of the  Non-U.S  Holder in the
United  States  (or,  in the case of  ordinary  income,  is from  United  States
sources;  i.e.,  is payable as the result of  services  performed  in the United
States) or (ii) in the case of a Non-U.S.  Holder who is an individual and holds
Class A common stock or Mojo B Common Stock as a capital  asset,  such Holder is
present in the United  States  for 183 days or more in the  taxable  year of the
sale and certain other  conditions are met.  Assuming the Liquidating  Trust and
Liquidating  Trust Escrow Fund are each classified as a trust for federal income
tax purposes  (see  discussion  below)  dividends  paid on the shares of Omnicom
Stock  held in the  Liquidating  Trust and  Liquidating  Trust  Escrow  Fund and
dividends paid on Omnicom Common Stock held in the Rightsholders or Stockholders
General or Special  Escrow Funds will be subject to withholding of United States
federal  income tax at a 30% rate or such lower rate as may be  specified  by an
applicable  income tax treaty,  unless the dividends are  effectively  connected
with the  conduct of a trade or business  of the  Non-U.S.  Holder in the United
States.  Under the current  United  States-  Australia  income tax  treaty,  for
example,  dividends are subject to withholding at a 15% rate. A Non-U.S.  Holder
who wishes to claim the benefit of an applicable  treaty rate may be required to
satisfy  applicable  certification  and other  requirements.  Dividends that are
effectively  connected with a trade or business in the United States are subject
to United States federal income tax on a net basis.

Liquidating Trust and Liquidating Trust Escrow Fund

     Holdings  believes that the  Liquidating  Trust and the  Liquidating  Trust
Escrow  Fund will each be  treated  as a grantor  trust for  federal  income tax
purposes and not as an association  taxable as a corporation.  As such, items of
taxable income,  deduction, gain and loss (including gain or loss on the sale of
shares of Omnicom  Common  Stock)  would be passed  through to the  Holders  and
reported  by them on their tax return  (whether  or not  distributed).  However,
since the Liquidating  Trust and the Liquidating Trust Escrow Fund will not meet
all of the IRS requirements to obtain a ruling as to grantor trust status, there
is a risk that the IRS could  successfully  assert that the Liquidating Trust or
the  Liquidating  Trust  Escrow Fund should be taxed as a  corporation.  In that
event, the Liquidating  Trust or the Liquidating Trust Escrow Fund would pay tax
on its income at the regular  corporate rates of up to 35% and any distributions
to  Holders  would be taxed as  dividends  at  ordinary  income tax rates to the
extent of the earnings and profits of the  Liquidating  Trust or the Liquidating
Trust Escrow Fund.

                               Withholding Taxes

     That portion of the Omnicom  Common Stock (and any cash received in respect
of fractional  shares)  which is taxable to Holders as ordinary or  compensation
income is subject to federal income tax  withholding  at the prescribed  rate of
28%, as well as FICA and other applicable federal,  state and local withholding.
Holdings  expects that Holders will make  arrangements  with Holdings to satisfy
their  tax  obligations.   A  Holder  who  fails  to  satisfy  this  withholding
requirement  could be subject to  potential  additional  estimated  tax  payment
liability  and to penalties if such  liability is not  satisfied.  If any person
receiving  shares of Omnicom  Common  Stock in respect  of his  employment  with
Holdings does not pay the relevant taxes, the Liquidating  Trust and the related
Liquidating Trust Escrow Fund would have liability for the amount of such tax.

     THE TAX  CONSEQUENCES  OF THE SALES OF ASSETS,  THE LIQUIDATION OF HOLDINGS
AND THE INCOME WITH RESPECT TO THE LIQUIDATING  TRUST,  LIQUIDATING TRUST ESCROW
FUND,  AND  ESCROW  FUNDS  MAY BE  INFLUENCED  BY THE  IRS'S  VIEWS  OF  FACTUAL

                    BUSINESS INFORMATION CONCERNING OMNICOM

     (The information  contained in this section is qualified in its entirety by
reference to documents incorporated by reference.)

     Omnicom,  through  its  wholly  and  partially  owned  companies,  operates
advertising  agencies  which  plan,  create,  produce and place  advertising  in
various media such as television,  radio,  newspaper and  magazines;  and offers
clients such  additional  services as marketing  consultation,  consumer  market
research,  design and production of merchandising  and sales promotion  programs
and materials,  direct mail advertising,  corporate  identification,  and public
relations.  Omnicom  offers  these  services  to clients  worldwide  on a local,
national,  pan-regional or global basis.  Operations  cover the major regions of
North America,  the United Kingdom,  Continental  Europe, the Middle East, Latin
America,  the  Far  East  and  Australia.   In  1994  and  1993,  54%  and  52%,
respectively, of Omnicom's billings came from its non-U.S. operations.

     According to the  unaudited  industry-wide  figures  published in the trade
journal,  Advertising  Age,  in 1994  Omnicom  was  ranked as the third  largest
advertising agency group worldwide.

     Omnicom  operates three separate,  independent  agency  networks:  the BBDO
Worldwide Network,  the DDB Needham Worldwide Network and the TBWA International
Network.  Omnicom also operates independent agencies,  Altschiller & Company and
Goodby,  Silverstein  & Partners,  and certain  marketing  service and specialty
advertising companies through Diversified Agency Services.

     BBDO Worldwide, DDB Needham Worldwide and TBWA International, by themselves
and through their respective subsidiaries and affiliates,  independently operate
advertising  agency  networks  worldwide.  Their  primary  business is to create
marketing  communications for their clients' goods and services across the total
spectrum of advertising and promotion media. Each of the agency networks has its
own clients and competes with each other in the same markets.

     The BBDO Worldwide,  DDB Needham Worldwide and TBWA International  agencies
typically  assign to each client a group of  advertising  specialists  which may
include account  managers,  copywriters,  art directors and research,  media and
production personnel.  The account manager works with the client to establish an
overall advertising strategy for the client based on an analysis of the client's
products or services and its market. The group then creates and arranges for the
production of the  advertising  and/or  promotion and purchases  time,  space or
access in the relevant media in accordance with the client's budget.

                    BUSINESS INFORMATION CONCERNING HOLDINGS

General

     The principal  line of business of Holdings and its  subsidiaries  includes
planning and creating  advertising  campaigns  for clients,  purchasing  various
media  spots  (television,  radio,  newspapers  and  magazines),  and  providing
marketing  consultation,  market  research  and  production  services.  In 1994,
Holdings was the 16th largest advertising agency in the U.S. and 27th largest in
the  world  according  to  statistics  published  in  Advertising  Age,  a trade
publication.  Holdings operates major offices in Venice, California, London, New
York and  Toronto,  and a  regional  network of offices  in,  Atlanta,  Calgary,
Chicago, Dallas, San Francisco, Washington, D.C. and Jacksonville. The principal
office of Chiat/Day is located at 180 Maiden Lane, New York, New York 10038.

Sales and Marketing

     Holdings  believes that it has a reputation as an industry  leader in terms
of the creativity and effectiveness of its campaigns. Holdings believes that its
reputation and the "Chiat/ Day" name are important generators of business.

     Holdings has organized  management  teams to explore and pursue  clients in
the major industry groups that it does not currently service. Holdings maintains
constant  contact with industry sources for new business leads and presents five
to eight extensive business pitches per office per year.

Customers

     Holdings  serves  a  diversified   and  well-known   client  base  in  many
industries,  including airlines,  automobile,  banking, cellular communications,
consumer  electronics,   entertainment,   financial  services,   food  products,
insurance,  footwear, personal computers and soft drinks. Eight of Holdings' ten
largest  clients  representing  57% of 1994 gross income have been with Holdings
for more than five years.

   
     Since 1988,  Nissan Motor Company has been  Holdings'  largest  client.  In
1992,  Nissan  awarded  its  Infiniti  account  to  Holdings  without  requiring
competitive  bids.  Nissan and Infiniti  accounted  for 48% of  Holdings'  gross
income in 1993 and 55% of Holdings' gross income in 1994.  Holdings has no other
client which accounts for 10% or more of its gross income.
    

     Like most advertising  agencies,  Holdings  experiences a certain amount of
client  turnover.  Agreements  between  Holdings  and its clients are  generally
terminable  by either  Holdings  or the client on 90 days  notice.  Turnover  is
primarily  generated by a change in the  management of the client,  an effort by
Holdings to pursue a client in the same category as an existing client, a client
merger or a change in the client's financial or strategic direction.

Competition

     Agencies  typically  pitch new  clients by  presenting  an ad  campaign  in
competition against other firms. The basis for the selection includes: relevance
of the  campaign to the  product  strategy,  creativity,  market  insights,  the
agency's  ability to provide the appropriate  media  exposure,  past success and
personal  chemistry.  Holdings believes that agencies are rarely selected on the
basis of price.  Typically,  agencies are precluded from  representing more than
one client in an industry for reasons of potential conflicts.

Services

     Holdings'  principal  line  of  business  includes  planning  and  creating
advertising campaigns for clients;  purchasing various media placements in local
television,  network,  cable,  radio,  newspapers,  magazines  and outdoor;  and
providing marketing, market research and production services.

     Holdings'  four major  offices (New York,  Venice,  Toronto and London) are
full service  operations with a total workforce of approximately  600, committed
to Account Management,  Account Planning,  Creative,  Media Planning and Buying,
and  Production.  The  offices  that  form  the  regional  network  with a total
workforce of approximately 150 support the localized needs of Holdings' national
clients.



                                       44

Pricing and Billing

     Holdings  generates  most of its  revenue  from  fees and  commissions  for
production  and  placement  in  various  media of agency  generated  advertising
campaigns.  Most of Holdings'  revenue is based on a combination  of commissions
and fees with seven of the ten largest  accounts on this  system.  This  pricing
method  provides a fixed  minimum  fee  augmented  by  commissions  based on the
client's  media  billings.  This pricing  method  protects the agency from large
variations in its clients' media budgets.

     Some clients are billed on a "cost plus mark-up" fee  structure.  Cost plus
mark-up  billing entails billing the client a fixed monthly fee for the staffing
dedicated to the account plus an amount to cover overhead.

     In  addition,  Holdings  is  sometimes  paid a bonus  by  clients  based on
predetermined performance criteria.

Billing and Accounting Practices

     Revenue  is  recognized  in the  month in which the  advertisement  is run.
"Advance  billings"  in the  current  liability  section  of the  balance  sheet
represents  costs and  commissions  which  have been  approved  by and billed to
clients but for which related vendor  invoices have not been received and income
has not been  earned.  "Expenditures  billable to clients" in the current  asset
portion of the balance  sheet  represents  unbilled  receivables.  Both "Advance
billings"  and  "Expenditures  billable to clients" are  primarily the result of
timing  differences  between the receipt of invoices  (media and production) and
the client billing cycle.

     For media placement,  Holdings obtains written approval of an estimate (the
"Estimate")  from its  clients  before  commitments  are made to media  vendors.
Clients are billed based on the approved Estimate.

     Production of advertising  spots follows a similar pattern,  except that in
this  case  Holdings  bills  the  client  as costs  are  incurred.  On  average,
production  costs  charged  to  clients  account  for about  10% of all  billing
activity.  Spot (local  television),  newspaper,  magazine and radio advertising
account for about 65% of billings.  Network advertising represents the remaining
25% of billings.

Seasonality

     Historically, Holdings' business has been seasonal, with increased billings
generated in the third and fourth  quarters of each fiscal year. The seasonality
generally  reflects the media  placement  patterns of  Holdings'  clients and is
similar to that experienced by other firms in the industry.

Personnel

   
     On  April  30,  1995,  Holdings  employed  approximately  750  persons.  In
addition,  turnover at the senior management level has been very low. All of the
eight senior  executives  of Holdings have been with Holdings for at least eight
years, with an average tenure of over 13 years.
    

     Since most  employees  are assigned to one specific  account,  Holdings can
respond  quickly to account losses or  acquisitions  by hiring or reducing staff
accordingly.

     None of Holdings' employees are represented by unions.

Legal Proceedings

     Holdings is not  involved in any material  pending  legal  proceedings  not
covered by insurance or by adequate indemnification, which, if decided adversely
to Holdings'  interest,  would have a material  adverse  effect on the financial
position of Holdings.

Properties

     All  of  Holdings'  offices  are  located  in  leased  premises.  Holding's
principal offices are in New York City and Venice.  Holdings also leases offices
in Calgary,  Chicago, Dallas, London, Toronto, San Francisco,  Washington,  D.C.
and Jacksonville.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                     AND RESULTS OF OPERATIONS OF HOLDINGS

                             Results of Operations

Fiscal year 1993  compared to fiscal year 1992 and fiscal year 1994  compared to
fiscal year 1993.

   
     Fee and commission  income decreased in fiscal years ended October 31, 1993
and 1994 by 22% and 11%,  respectively,  compared to the prior fiscal years. The
decrease in fiscal year 1993 was mainly attributable to the loss of the American
Express and Nutrasweet accounts and the sale of Holdings' Australian  subsidiary
in February 1993. The fiscal year 1994 decrease was mainly  attributable to loss
of the Reebok account.

     Salaries and employee  benefit  expenses were reduced by 19% in fiscal year
1993 and 8% in fiscal year 1994,  respectively,  as compared to the prior fiscal
years.  Due to the reduction in fee and  commission  income in fiscal years 1993
and 1994,  staff  reductions  were made to reduce  costs.  Selling,  general and
administrative  expenses  decreased  in fiscal year 1993 by 14% from fiscal year
1992 due to the disposal of Holdings' Australian subsidiary in February 1993. In
fiscal year 1994,  Holdings  established a "virtual  office" in its New York and
Venice offices by eliminating fixed office locations for personnel. Holdings and
Advertising  employees carry portable phones and computers and are encouraged to
work where they feel most productive. Based on the implementation of the virtual
office, selling, general and administrative expenses were reduced in fiscal year
1994 by 29% compared to fiscal year 1993.  This  reduction  was primarily due to
decreases in real estate and depreciation expense by 41% and 47%,  respectively,
as a result of the  restructuring  charge recorded in 1993 described in the next
paragraph.

     A one-time  restructuring charge of $25,848,000 was recorded in fiscal year
1993.  Effective  November  1,  1993  Holdings  entered  into a new real  estate
operating  lease in New York that will  enable it to  significantly  reduce  its
future  rental  expense  through a reduction  in total  amount of space  leased.
Holdings  remains  as the  primary  lessee  on its old New  York  lease  through
December  31,  1997.  It has  currently  sublet  approximately  85% of the space
through the lease term and is actively  seeking to sublet the  remaining  space.
$14,802,000 of the charge relates to the future cash rental obligations,  net of
probable sublease income, and $3,252,000 relates to the writeoff of fixed assets
and leasehold improvements.

     In fiscal  1993  Holdings  entered  into  agreements  to assign  its lease,
effective  January 1, 1994,  for the 320 Hampton Drive  facility to an unrelated
third party in order to  consolidate  operations  into one  facility at 340 Main
Street.  All fixed assets and  leasehold  improvements  related to such facility
were written off in 1993.  Alterations to the 340 Main Street property were made
in order to facilitate the  consolidation  into one facility.  $5,122,000 of the
restructuring  charge  related to the  write-off of leasehold  improvements  and
fixed assets at both  facilities as a result of the  consolidation  and $940,000
related to cash obligations incurred in connection with the lease assignment and
consolidation of space.  The remaining  balance of the  restructuring  charge of
$1,732,000  represents a reserve for future cash rental obligations in excess of
anticipated probable sublease income for other property leased in California.

     In 1994 earnings increased by approximately $4,500,000 due to reductions in
rental and depreciation  expense as a result of the restructuring  reserve taken
in  1993.   Cash  flows  decreased  in  1994  primarily  due  to  $5,800,000  of
expenditures  incurred in connection with the  alterations  made to the 340 Main
Street  facility.  Future earnings and cash flows will increase by approximately
$4,500,000  and $2,000,000  per annum,  respectively,  due to reduced rental and
depreciation expense.

     In October 1994,  Venice  Operating Corp.  ("VOC"),  a company owned by the
majority  stockholder and certain members of the Board of Directors of Holdings,
sold its office  facilities in Venice,  California to an unrelated  third party.
Effective  October 14, 1994 the Holdings  lease with VOC was  terminated  and it
entered into a new twenty year lease having six  consecutive  five-year  renewal
options  with the new owner of the  building.  Rent  expense  will be reduced by
approximately $1,000,000 per annum as a result of such new lease.

     Holdings  was  assigned  a  $3,000,000  promissory  note  from  VOC that it
received in  connection  with the sale of the  building in  satisfaction  of the
return of the Holdings'  security  deposit and accrued interest thereon due from
VOC. As a result of the proposed  transaction with Omnicom, the new owner of the
building and obligor of the note, ADS (CA) QRS,  11-34,  has indicated that they
    

                                       47

will pay the  principal in full prior to December 31, 1995.  VOC is presently an
inactive  company  and  Holdings  has  had no  business  transactions  with  VOC
subsequent to the sale of the building.

     On February 16,1993,  (effective as of January 1, 1993), Holdings completed
the transfer of the stock of this subsidiary to Foote Cone & Belding ("FCB") for
no  consideration.  Concurrent  with the  transfer  of shares  to FCB,  Holdings
exercised its option to acquire $10,350,000 of bank debt owed by such subsidiary
for $700 and  agreed to accept  from FCB,  in full  satisfaction  of such  debt,
$1,380,000  plus future  contingent  payments up to a maximum of $3,450,000.  To
date, Holdings has received $1,093,000 from FCB in contingent payments. Holdings
recorded a gain of  $3,504,000 on the  disposition  primarily as a result of the
recognition of the accumulated translation adjustment related to such operation.
FCB already had a presence in  Australia  and felt that the  combination  of the
operations could provide future value. The disposition was structured to reflect
the fact that the level of debt rendered the equity worthless.  Accordingly,  no
consideration was paid for the stock. Due to the uncertainty of the viability of
the  operation,  payments  to  Holdings  were  contingent  upon  future  revenue
performance  and the  utilization of certain tax benefits by FCB. All contingent
payments  by FCB are  recorded  when  received.  While the  disposition  reduced
overall revenues of Holdings, it increased Holdings' consolidated  profitability
due to the elimination of the net operating losses the subsidiary was generating
as a result of poor  operating  performance  and high interest  costs due to its
large debt  position.  The reduction in  consolidated  debt  improved  Holdings'
overall financial position and cash flows.

     The 73% decrease in other  operating  expenses in fiscal year 1993 compared
to fiscal  year 1992 was due  largely  to the impact of a  $3,200,000  charge in
fiscal year 1992 to reflect the settlement of certain litigation.  An additional
90%  reduction  in other  operating  expenses  was  realized in fiscal year 1994
compared to fiscal year 1993  primarily  due to $653,000 of revenue  performance
payments received in connection with the sale of Holdings' Australian subsidiary
discussed above and due to increased  deferred  compensation  expenses in fiscal
year 1993 of approximately $1,000,000.

     Interest  expense was reduced by 41% in fiscal year 1993 versus fiscal year
1992 due to reduced levels of debt. A 1% increase in interest  expense in fiscal
1994 versus fiscal 1993 was due to an increase in dividends issued to the profit
sharing plan in 1994.

     The income tax  provision  for fiscal year 1993  decreased  64% compared to
fiscal  year 1992 due  largely to the use in fiscal  year 1993 of net  operating
loss  carry  forwards  previously  generated.  While the  income  tax  provision
increased 87% in fiscal year 1994  compared to fiscal year 1993,  the income tax
provision was less than what would have been provided  under the statutory  rate
due to the use of net  operating  loss carry  forwards  and a foreign tax credit
generated in fiscal year 1994.  FASB 109 was adopted  effective  October 1, 1993
creating a deferred  tax asset of  $18,717,000.  No benefit was  recorded on the
financial statements, but the effect is described in the footnotes.

First half 1995 compared to first half 1994.

     For the six month ended April 30, 1995,  revenues  increased 6% compared to
the  corresponding  period  of the  prior  year as a result  of new  clients  in
California and New York. At the same time,  salary expense  increased by 20% due
to salary  increases  effective May 1, 1994, the full effect of new hires in the
Toronto office and incremental staffing for new business wins occurring in 1995.
Selling,  general and  administrative  expense decreased by 16% due to decreased
rent expense related to lower lease costs in New York and California as a result
of new leases  entered into for both  locations.  Due to  increased  borrowings,
interest  expense  increased  by 21%  while  interest  income  increased  by 44%
resulting  in a net  interest  expense  increase  of  15%.  Income  tax  expense
increased as a result of an increase in the expected  effective  income tax rate
in 1995.
    

                        Liquidity and Capital Resources

   
     Holdings'  principal source of operating  capital has been from operations,
Senior Debt of $20,000,000  under the Amended and Restated Credit  Agreement and
Senior  Subordinated  Debt of $11,000,000  under the 13.25% Senior  Subordinated
Notes.  The Senior Debt is due and  payable on December  10, 1995 and the Senior
Subordinated  Debt became payable and was paid on August 1, 1995. Under the Bank
Credit Agreement,  the Senior Debt was scheduled to mature in May 1995. However,
pursuant to the  assignment  to Omnicom of the Senior Debt in January 1995 under
    


                                       48
<PAGE>

   
the Amended and Restated Credit Agreement, Omnicom agreed to extend the maturity
until  December 10, 1995.  In the event the  Transactions  are not  consummated,
Holdings  would be required to refinance  its entire debt  structure by December
10, 1995.

     In late 1994 and January  1995,  Holdings was engaged in  discussions  with
potential lenders regarding the refinancing of the Bank Credit Agreement and $11
million of Holdings'  13.25%  Senior  Subordinated  Notes which matured and were
paid in full on August 1, 1995. The terms proposed by prospective  institutional
lenders included substantial penalties for early repayment and the equivalent of
an equity  participation  in  Holdings in the event that it were sold while such
financing was outstanding. During the period Holdings was considering whether to
accept such terms of  refinancing,  discussions  with  Omnicom  were renewed and
began to assume the characteristics of negotiations in January of 1995. Holdings
realized that proceeding with the proposed  refinancing would create significant
obstacles to consummating  any acquisition  transaction.  Instead,  as described
above,  Omnicom  agreed to assume the  liabilities  of the banks  under the Bank
Credit Agreement and extended the maturity until December 10, 1995.

     Based upon the discussions  held with prospective  lending  institutions in
late 1994 and early 1995,  management believes that the refinancing of Holdings'
outstanding  debt  obligations  and/or  additional  equity  financing  would  be
obtainable if necessary, although no assurances can be given. If the Acquisition
is  not   consummated,   Holdings  will  resume   discussions   with   potential
institutional lenders and/or equity investors.  If such financing were obtained,
given  Holdings'  historical  increases  in cash  and cash  equivalents  and its
ability to manage its negative  working capital  position,  management  believes
that Holdings would continue as a viable going concern.

     Working  capital  decreased in fiscal year 1994 by 15.7% versus fiscal year
1993. As compared to April 30, 1994, working capital at April 30, 1995 increased
by 126.5% primarilydue to long term debt becoming current.

     Holdings' working capital deficit increased to $64.9 million at October 31,
1994  from  $56.1  million  at  October  31,  1993   primarily  due  to  capital
expenditures of $5.8 million in 1994 to implement the real estate restructuring.

     Capital  expenditures  of  $999,000  were  made in  fiscal  year  1993  and
$5,615,000 in fiscal year 1994. These expenditures included, among other things,
leasehold improvements and upgraded telephone and computer systems.
     

     Holdings  believes that its cash flows and funds  available  under existing
debt  facilities  will be  adequate  to meet its cash  requirements  through the
contemplated Closing Date of the Acquisition, but it is possible that additional
borrowings from Omnicom may be required.

     Following the  Acquisition  and the dissolution and liquidation of Holdings
described  herein  there will be no Class A Common Stock or Class B Common Stock
outstanding and none of the current  directors and officers of Holdings will own
in excess of 1% of Omnicom Common Stock.
    

     No  dividends  have been  declared or paid on the  Holdings  Class A Common
Stock or  Class B Common  Stock in the  current  fiscal  year,  or in any of the
periods  presented in "Selected  Financial  Data of  Holdings".  Pursuant to the
Amended and Restated  Credit  Agreement,  Advertising is prohibited  from paying
dividends other than dividends paid in shares.

     There is no established trading market for Holdings Class A Common Stock or
Class B Common Stock.

Holdings Preferred Stock

   
     There are 200,000 shares of Holdings Preferred Stock authorized. There were
140,817.7393  shares  outstanding  at April 30, 1995, all of which were owned by
the Profit Sharing Plan. All such shares were reacquired by Holdings on July 10,
1995 pursuant to the terms of the Profit Sharing Plan Purchase Agreement, for an
amount in cash of $14,081,773.93 (or $100 per share).

      Holdings  Preferred  Stock  provides for cumulative  dividends  payable in
cash, or at Holdings' option,  in shares of Holdings  Preferred Stock (valued at
$100 per share) or a combination of cash and shares of Holdings  Preferred Stock
at a rate equal to 9% per annum of the  liquidation  preference of all shares of
Holdings Preferred Stock  outstanding,  if such amount is paid entirely in cash,
or at a rate of 10% per annum of the  liquidation  preference  if such amount is
paid entirely in additional shares of Holdings  Preferred Stock, or at a blended
rate based  upon the  weighted  average of (i) the number of shares of  Holdings
Preferred Stock in respect of which dividends are paid in cash multiplied by 9%,
and (ii) the  number  of  shares  in  respect  of  which  dividends  are paid in
additional  shares of Holdings  Preferred Stock multiplied by 10%. All dividends
on shares of Holdings  Preferred Stock are payable,  if, when and as declared by
the Board of Directors, annually in arrears on August 1, of each year. Dividends
in respect of shares of  Holdings  Preferred  Stock had been  declared  annually
since  issuance  in July of each  year  and had  been  paid by the  issuance  of
additional  shares of Holdings  Preferred Stock. Any dividends in arrears on the
Holdings  Preferred  Stock  accrue  dividends  at the rate of 9% per annum.  The
holders of Holdings  Preferred  Stock are not entitled to vote on any  corporate
matters, except as required by law. In the event of liquidation,  the holders of
Holdings  Preferred Stock are entitled to receive the amount of $100 in cash for
each outstanding share of Holdings  Preferred Stock plus all declared and unpaid
dividends  before any  distribution  to the  holders of Class A Common  Stock or
Class B Common  Stock.  If the  assets  available  are  insufficient  for such a
payment,  the holders of  Holdings  Preferred  Stock shall share  ratably in any
distribution.  Subject to the prior payment of certain  senior  indebtedness  of
Advertising, the Holdings Preferred Stock may be redeemed at Holdings' option on
and after  July 31,  1996 at a price of $100 per share plus  accrued  but unpaid
dividends subject to certain restrictions  provided in the Holdings Certificate.

of Class A Common Stock and Class B Common Stock entitled to vote outstanding on
the record date is  necessary  to  constitute  a quorum at the Special  Meeting.
Under the DGCL and the Holdings  Certificate the affirmative vote of the holders
of the  majority of the  outstanding  shares of Class A Common Stock and Class B
Common  Stock  voting  together as a class,  are required to approve each of the
sales  pursuant  to  the  Acquisition   Agreement  and  Advertising  Stock  Sale
Agreement,   the  Plan  of  Liquidation   and  the  Amendment  to  the  Holdings
Certificate.  Abstentions  will have the effect of  negative  votes.  Directors,
officers  and  affiliates  of  Holdings  who hold in the  aggregate  more than a
majority of the outstanding Class A Common Stock and Class B Common Stock in the
aggregate  have  indicated  their  intention  to  vote in  favor  of each of the
Holdings Vote Matters.  See "The  Transactions--Interests  of Certain Persons in
the  Transactions."  Accordingly,  if such  persons  vote in favor of these  the
Transactions,   they  may  be  approved  even  if  all  of  the  other  Holdings
Stockholders vote against these proposals.

     None of the Holdings Vote Matters shall become  effective unless all of the
proposals are adopted by the requisite vote of the Holdings Stockholders.

Rights of Dissenting Holdings Stockholders

     It is intended that the transactions  described herein,  including the sale
of the assets and the  distribution to the Holdings  Stockholders in liquidation
of  Holdings,  will not give rise to  dissenters'  rights  in favor of  Holdings
Stockholders under Delaware law.

Equity Appreciation Rights

   
     Pursuant to the EAR Plan,  Holdings has authorized  54,084,848 EARs each of
which is  equivalent  to one  share of  Class B  Common  Stock  and has the same
priority as Class B Common Stock in the event of a  liquidation.  In the absence
of  liquidation,  the EARs are valued at their net book  value,  which was $0 at
April  30,  1995.  At the  close of  business  on August  1,  1995,  there  were
36,939,112 EARs  outstanding.  At the Closing Date, all of the outstanding  EARs
will be vested.
    

Equity Participation Units

   
     Pursuant to the EPU Plan, Holdings has authorized  50,000,000 EPUs, each of
which is  equivalent  to one  share of  Class B  Common  Stock  and has the same
priority as Class B Common Stock in the event of a  liquidation.  In the absence
of  liquidation,  the EPUs are valued at their net book  value,  which was $0 at
April 30, 1995. At August 1, 1995 there were 22,198,890 EPUs outstanding. At the
Closing Date all of the EPUs will be vested.
    

                        COMPARISON OF SHAREHOLDER RIGHTS

   
     Upon  consummation  of the  Acquisition  and the subsequent  dissolution of
Holdings  and  distribution  of  shares  of  Omnicom  Common  Stock to  Holdings
Stockholders  and  Rightsholders,  the  stockholders  of  Holdings,  a  Delaware
corporation,  will become  shareholders of Omnicom, a New York corporation,  and
their  rights as such will be  governed  by New York law, as well as the Omnicom
Certificate  of  Incorporation  (the  "Omnicom  Certificate")  and By-laws  (the
"Omnicom By-laws") as amended from time to time in accordance with New York law.
While it is not  practical  to  describe  all  changes in the rights of Holdings
stockholders  that will result from the  application  of New York law in lieu of
Delaware law and the differences between the Omnicom Certificate and the Omnicom
By-laws and the Holdings  Certificate  and the Holdings  By-laws (the  "Holdings
By-laws"), the following is a summary of material differences.
    

     References  to the "NYBCL" are to the New York  Business  Corporation  Law,
while references to the "DGCL" are to the Delaware General Corporation Law.

Special Meetings of Stockholders

     Under Delaware law, a special meeting of stockholders may be called only by
the board of directors or by such person as may be authorized by the certificate
of incorporation or by-laws. The Holdings By-laws provide that a special meeting
of  stockholders  may be called by the Board of  Directors,  the Chairman of the
Board or the President and shall be called by the Board upon the written request
of the holders of record of a majority  of the  outstanding  shares  entitled to
vote at the meeting requested to be called.

     Under New York law, a special meeting of shareholders  may be called by the
board of directors  and by such person or persons as may be  authorized to do so
in the  certificate  of  incorporation  or by-laws.  In  addition,  if an annual
shareholder  meeting  has not  been  held  for a  certain  period  of time and a
sufficient  number of directors  were not elected to conduct the business of the
corporation,  the  board  shall  call a  special  meeting  for the  election  of
directors.  If the board fails to do so, or sufficient directors are not elected
within a certain  period,  holders of 10% of the shares  entitled  to vote in an
election  of  directors  may call a special  meeting for such an  election.  The
Omnicom By-laws  provide that a special  meeting of shareholders  may be called,
for any purpose or purposes,  by the Board of Directors or by the President,  or
by the Secretary upon the request of a majority of the Board of Directors.


                                       53

Removal of Directors

     Under  Delaware  law,  unless  otherwise  provided  in the  certificate  of
incorporation  or the by-laws,  shareholders  may remove any  director,  with or
without  cause,  by the  affirmative  vote of the  holders of a majority  of the
shares then entitled to vote at an election of directors.  The Holdings  By-laws
provide  that  directors  may be removed  with or  without  cause by vote of the
stockholders.

     Under New York law, (i) shareholders may remove any director for cause, and
the  certificate or provision of a by-law adopted by the  shareholders  may give
the board  such  right;  (ii) if the  certificate  or the  by-laws  so  provide,
shareholders may remove directors without cause; and (iii) an action to remove a
director for cause may be brought by the  attorney-general  or by the holders of
ten percent of the outstanding shares,  whether or not entitled to vote. Neither
the Omnicom  Certificate nor the Omnicom By-Laws permit the removal of directors
other than for cause.

Vacancies On The Board

     Under  Delaware  law,  unless  otherwise  provided  in the  certificate  of
incorporation or the by-laws, the board of directors may fill any vacancy on the
board including vacancies resulting from an increase in the number of directors.
Under the Holdings  By-laws,  vacancies  on the Board for any reason  (including
vacancies  resulting  from an  increase in the number of  directors)  except the
removal of  directors by  stockholders  (which may only be filled by vote of the
stockholders)  may be  filled by vote of a  majority  of the  directors  then in
office. A director elected to fill a vacancy shall be elected to hold office for
the unexpired term of his predecessor.

     Under New York law, newly created directorships  resulting from an increase
in the number of directors and  vacancies  occurring in the board for any reason
except  the  removal  of  directors  without  cause may be filled by vote of the
board.  However,  the certificate of  incorporation  or by-laws may provide that
such newly  created  directorships  or vacancies are to be filled by vote of the
shareholders.  Unless the certificate of incorporation or the specific provision
of a  by-law  adopted  by the  shareholders  provide  that  the  board  may fill
vacancies  occurring in the board by reason of the removal of directors  without
cause, such vacancies may be filled only by vote of the shareholders. A director
elected to fill a vacancy, unless elected by the shareholders,  will hold office
until the next meeting of  shareholders at which the election of directors is in
the regular  order of business and until his or her  successor  has been elected
and qualified. The Omnicom By-laws provide that any vacancy in the Omnicom Board
may  be  filled  by a  majority  vote  of  the  remaining  directors  or by  the
shareholders.

Classification of the Board of Directors

     Holdings' Board of Directors is not classified into classes.

     Omnicom's  Certificate of  Incorporation  provides that directors are to be
classified into three classes,  which are to hold office in staggered three-year
terms.

Books and Records; Inspection

     Under Delaware law, any person who is a shareholder of record has the right
to examine,  for any  purpose  reasonably  relating to his or her  interest as a
shareholder,  the minutes of a corporation and the right to receive upon request
certain financial statements of the corporation.

     Under New York law, only shareholders of record for at least six months and
any person or the  authorized  agent of any  person or persons  holding at least
five  percent of any class of the  outstanding  shares have the right to examine
the  minutes of a  corporation  and the right to receive  upon  request  certain
financial  statements of the  corporation.  Under the federal  securities  laws,
shareholders  of  Omnicom  receive  financial  information   substantially  more
extensive than that required under New York law.

Amendments of the Certificate of Incorporation

     Under  Delaware  law, an  amendment  to the  certificate  of  incorporation
proposed by the board of directors requires an affirmative vote of a majority of
the  outstanding  stock  entitled  to  vote  thereon,  and  a  majority  of  the
outstanding stock of each class entitled to vote as a class thereon.  Whether or
not entitled by the charter,  the holders of the  outstanding  shares of a class
are entitled to vote as a class on a charter  amendment if the  amendment  would


                                       54
<PAGE>

increase or decrease the aggregate number of authorized  shares of such class or
adversely  affect the powers,  preferences or special  rights of such class.  In
addition,  the Holdings  Certificate  specifically  requires the approval of the
holders of a majority  of the shares of Class A Common  Stock  (excluding  those
shares  originally issued to Morgan Capital  Corporation)  voting separately for
any amendment to the Holdings Certificate which adversely affects their rights.

     Under  New  York  law,  an  amendment  or  change  of  the  certificate  of
incorporation  may be authorized  by vote of the Board,  followed by vote of the
holders  of a majority  of all  outstanding  shares  entitled  to vote  thereon.
Certain  categories  of  amendments  which  adversely  affect  the rights of any
holders of shares of a class or series of stock require the affirmative  vote of
the  holders of a majority  of all  outstanding  shares of such class or series,
voting separately.  The Omnicom Certificate  requires the affirmative vote of 66
2/3% of the voting power of all outstanding shares of voting stock of Omnicom in
order to amend or repeal the provisions of the Omnicom  Certificate  setting the
number of directors  constituting the entire Board of Directors and dividing the
directors into classes, and absolving directors from personal liability pursuant
to Section 719 of the NYBCL.

Amendments to By-Laws

     Under  Delaware law, the by-laws of a corporation  generally may be amended
or repealed by the  affirmative  vote of the holders of a majority of the shares
entitled to vote thereon. As permitted by the DGCL, the Holdings By-laws provide
that the  Holdings  By-laws may be made,  altered or  repealed  by the  Holdings
Board.  Any By-law  adopted by the Holdings  Board may be amended or repealed by
the stockholders entitled to vote thereon. In addition, the Holdings Certificate
specifically requires the approval of the holders of a majority of the shares of
Class A Common Stock (excluding those shares originally issued to Morgan Capital
Corporation)  voting  separately for any amendment to the Holdings By-laws which
adversely affects their rights.

     Under New York law,  except as  otherwise  provided in the  certificate  of
incorporation,  by-laws  may be  amended,  repealed or adopted by the holders of
shares entitled to vote in the election of any director. When so provided in the
certificate of  incorporation or a by-law adopted by the  shareholders,  by-laws
may also be  amended,  repealed  or  adopted by the board by such vote as may be
therein  specified,  which may be greater than the vote otherwise  prescribed by
law,  but any by-law  adopted by the board may be  amended  or  repealed  by the
shareholders  entitled  to  vote  thereon.   Under  the  terms  of  the  Omnicom
Certificate and Omnicom  By-laws,  Omnicom  By-laws may be amended,  repealed or
adopted  only by the  affirmative  vote of at least 66 2/3% of the total  voting
power of all outstanding shares of voting stock of Omnicom.

Dividends and Distributions

     Delaware law permits the payment of dividends on capital stock,  subject to
any  restrictions  contained  in  the  certificate  of  incorporation,  out of a
corporation's  surplus (the excess of net assets over capital) or, in case there
is no surplus,  out of net profits for the current and/or preceding fiscal year.
If the  capital of the  corporation  is  diminished  to an amount  less than the
aggregate  amount of  capital  represented  by the  outstanding  stock  having a
preference on the distribution of assets, then dividends may not be declared and
paid out of such net  profits  until the  deficiency  in the  amount of  capital
represented  by the shares  having a preference  on the  distribution  of assets
shall have been  repaired.  The Holdings  Certificate  provides that unless full
cumulative  dividends on the Holdings Preferred Stock have been paid or declared
in full and sums set  aside  for  their  payment,  no  dividends  may be paid or
declared on the Class A Common  Stock or Class B Common  Stock.  The Amended and
Restated  Credit  Agreement  prohibits  the  payment  of  dividends  other  than
dividends paid in shares.

     Under  New  York  law,   dividends  may  be  declared  or  paid  and  other
distributions  may be made out of  surplus  only,  so that the net assets of the
corporation  remaining after such  declaration,  payment or distribution must at
least equal the amount of its stated  capital.  When any dividend is paid or any
other  distribution  is made from sources other than earned  surplus,  a written
notice must accompany such payment or  distribution  as provided by the NYBCL. A
corporation  may declare and pay  dividends or make other  distributions  except
when currently the  corporation is insolvent or would thereby be made insolvent,
or when the  declaration,  payment  or  distribution  would be  contrary  to any
restrictions contained in the corporation's certificate of incorporation.

State Takeover Legislation

     Section 203 of the DGCL prohibits a publicly held Delaware corporation from
engaging in a "business  combination"  with an  "interested  stockholder"  for a
period  of  three  years  after  the  date  such  person  became  an  interested
stockholder,  unless (i) prior to such date,  the  business  combination  or the
transaction which resulted in the stockholder becoming an interested stockholder
is approved by the board of directors of the corporation, (ii) upon consummation
of the  transaction  which  resulted in the  stockholder  becoming an interested
stockholder,  the interested  stockholder  owned at least 85% of the outstanding
voting  stock  of the  corporation  outstanding  at  the  time  the  transaction
commenced,  or (iii) on or after such date the business  combination is approved
by the board of directors of the corporation and by the affirmative vote, not by
written  consent,  of at least 66 2/3% of the voting stock which is not owned by
the  interested   stockholder.   A  "business   combination"  includes  mergers,
consolidations,  asset transfers (including any sale, lease, exchange, mortgage,
pledge or other  disposition  of assets) and other  transactions  resulting in a
financial benefit to the interested stockholder.  An "interested stockholder" is
a  person  who (i)  owns  15% or more of the  outstanding  voting  stock  of the
corporation  or (ii) is an affiliate or associate of a  corporation  and was the
owner of 15% or more of the outstanding voting stock at any time within the past
three years.

     The NYBCL prohibits any business  combination (defined to include a variety
of transactions,  including  mergers,  consolidations,  sales or dispositions of
assets, issuances of stock,  liquidations,  reclassifications and the receipt of
certain  benefits from the  corporation,  including  loans or guarantees)  with,
involving or proposed by any interested  shareholder  (defined  generally as any
person who, (i)  directly or  indirectly,  beneficially  owns 20% or more of the
outstanding  voting stock of a resident domestic New York corporation or (ii) is
an affiliate or associate of such resident domestic  corporation and at any time
within the past five years was a beneficial  owner of 20% or more of such stock)
for a period of five years  after the date on which the  interested  shareholder
became  such.  After  such  five-year  period a business  combination  between a
resident  domestic  New York  corporation  and such  interested  shareholder  is
prohibited  unless either  certain "fair price"  provisions are complied with or
the business  combination  is approved by a majority of the  outstanding  voting
stock not beneficially owned by such interested shareholder or its affiliates or
associates.  The NYBCL exempts from its  prohibitions  any business  combination
with an interested shareholder if such business combination,  or the purchase of
stock by the interested shareholder that caused such shareholder to become such,
is  approved  by the  board  of  directors  of the  resident  domestic  New York
corporation prior to the date on which the interested shareholder becomes such.

     Section  203 of the DGCL does not apply to  Holdings,  as Holdings is not a
publicly held corporation as defined by the DGCL. Under the NYBCL,  corporations
may opt to not be governed by the statute; Omnicom has not so elected.

Business Combinations

     Generally,  under  the  DGCL,  the  affirmative  vote of the  holders  of a
majority of the outstanding shares entitled to vote on the matter is required to
approve mergers,  consolidations,  and any sales,  leases or exchanges of all or
substantially  all of the  assets of a  corporation.  The  Holdings  Certificate
requires in addition  the approval of the holders of a majority of the shares of
Class A Common Stock (excluding the shares  originally  issued to Morgan Capital
Corporation)  voting  separately  as a class  for  any  such  transactions.  The
Holdings  Certificate further provides that this requirement shall not prevent a
merger,  consolidation or asset sale if the consideration  received by Holdings,
its  subsidiaries  and holders of shares of Class A Common Stock consists solely
of cash or freely tradeable registered securities or a combination thereof.

     Under the NYBCL,  the affirmative  vote of the holders of two-thirds of all
outstanding  shares of stock of a New York corporation  entitled to vote thereon
is  required  to approve  mergers  and  consolidations,  and for sales,  leases,
exchanges  or other  dispositions  of all or  substantially  all the assets of a
corporation, if not made in the usual or regular course of the business actually
conducted by such corporation.

Rights of Dissenting Shareholders

     Delaware law grants appraisal  rights to any stockholder  opposing a merger
or consolidation  (except that it restricts the appraisal rights of shareholders
of the merging domestic corporation which is to be the surviving  corporation by
eliminating appraisal rights for such shareholders if the merger did not require
for  its  approval  the  vote  of the  holders  of the  surviving  corporation).


                                       56
<PAGE>

Accordingly,  a dissenting  shareholder  is entitled to receive in cash the fair
value of his shares as determined by the Delaware Court of Chancery in the event
the merger or consolidation is consummated.

     Shareholders of a New York  corporation  have the right to dissent not only
in the  context of a merger or  consolidation,  but also in the event of certain
amendments or changes to the certificate of  incorporation  adversely  affecting
their  shares,  certain  sales,  exchanges  or  other  dispositions  of  all  or
substantially all of the corporation's assets and certain share exchanges.

Indemnification of Directors, Officers and Employees

     Section 145 of the DGCL generally  provides that a corporation  may, and in
certain circumstances,  must, indemnify any person who is or was threatened with
any action,  suit or proceeding by reason of the fact that he or she is or was a
director, officer, employee or agent of such corporation for expenses, judgments
or  settlements  actually and  reasonably  incurred by such person in connection
with suits and other legal  action or  proceedings  if such person acted in good
faith and in a manner he or she  reasonably  believed to be in or not opposed to
the best interests of the  corporation  and, with respect to any criminal action
or  proceeding,  had no reasonable  cause to believe their conduct was unlawful.
The determination of whether a director,  officer, employee or agent has met the
applicable  standard  of conduct  is made (i) by a majority  vote of a quorum of
directors not party to the action, suit or proceeding, or (ii) by an independent
legal  counsel in a written  opinion if a quorum of  disinterested  directors is
unobtainable  or if the  disinterested  directors  so  direct  or  (iii)  by the
shareholders.  In the case of shareholder  derivative suits, the corporation may
indemnify  any  person  who  is or was  threatened  with  any  action,  suit  or
proceeding  by reason of the fact that he or she is or was a director,  officer,
employee or agent if such  person  acted in good faith and in a manner he or she
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation, except that no indemnification may be made in respect of any claim,
issue or matter as to which such person shall have been  adjudged  liable to the
corporation  unless and only to the  extent  that the Court of  Chancery  or the
court in which the action was brought  determined upon application that, in view
of all the  circumstances  of the case,  the  person is  fairly  and  reasonably
entitled to indemnity for such expenses as the court deems proper. The DGCL also
permits a corporation to adopt  procedures for advancing  expenses to directors,
officers  and  others  without  the need  for a  case-by-case  determination  of
eligibility,  so long as in the case of officers and directors they undertake to
repay the amounts  advanced if it is ultimately  determined  that the officer or
director  was not  entitled to be  indemnified.  The  aforementioned  provisions
relating to indemnification  and advancement of expenses are not exclusive and a
corporation may provide  additional rights to those seeking  indemnification  or
advancement of expenses.  The Holdings  Certificate provides for indemnification
of directors,  officers,  employees and agents to the fullest extent  authorized
under the DGCL. The Holdings  Certificate  also  authorizes  the  advancement of
expenses relating to actions for which such persons may be indemnified.

     Under  Section 722 of the NYBCL,  a  corporation  may  indemnify any person
made, or threatened to be made, a party to any action or proceeding,  except for
shareholder  derivative  suits,  by  reason  of the  fact  that  he or she was a
director or officer of the corporation,  provided such director or officer acted
in good faith for a purpose  which he or she  reasonably  believed  to be in the
best interests of the corporation and, in criminal proceedings, in addition, had
no reasonable  cause to believe his or her conduct was unlawful.  In the case of
shareholder derivative suits, the corporation may indemnify any person by reason
of the fact that he or she was a director or officer of the corporation if he or
she acted in good faith for a purpose which he or she reasonably  believed to be
in the best interests of the corporation,  except that no indemnification may be
made in respect of (i) a threatened action, or a pending action which is settled
or otherwise  disposed  of, or (ii) any claim,  issue or matter as to which such
person has been adjudged to be liable to the corporation, unless and only to the
extent  that the court in which the  action  was  brought,  or, if no action was
brought, any court of competent jurisdiction,  determines upon application that,
in  view of all  the  circumstances  of the  case,  the  person  is  fairly  and
reasonably  entitled to indemnity for such portion of the settlement  amount and
expenses as the court deems proper.

     The  indemnification  described  above under the NYBCL is not  exclusive of
other  indemnification  rights to which a director or officer  may be  entitled,
whether  contained in the  certificate  of  incorporation  or by-laws,  or, when
authorized  by  (i)  such  certificate  of  incorporation  or  by-laws,  (ii)  a
resolution  of  shareholders,  (iii)  a  resolution  of  directors,  or  (iv) an


                                       57
<PAGE>

agreement providing for such  indemnification,  provided that no indemnification
may be made to or on behalf of any  director  or officer if a judgment  or other
final  adjudication  adverse to the director or officer  establishes that his or
her acts were committed in bad faith or were the result of active and deliberate
dishonesty and were material to the cause of action so  adjudicated,  or that he
or she personally  gained in fact a financial profit or other advantage to which
he or she was not legally entitled.

     Any  person  who has been  successful  on the  merits or  otherwise  in the
defense  of a civil  or  criminal  action  or  proceeding  will be  entitled  to
indemnification. Except as provided in the preceding sentence, unless ordered by
a court pursuant to the NYBCL, any  indemnification  under the NYBCL pursuant to
the above  paragraphs  may be made only if  authorized  in the specific case and
after a finding  that the  director  or officer  met the  requisite  standard of
conduct (i) by the disinterested  directors if a quorum is available, or (ii) in
the event a quorum of disinterested  directors is not available or so directs by
either (A) the board upon the written opinion of independent  legal counsel,  or
(B) by the shareholders.

     The Omnicom By-laws provide that Omnicom shall provide  indemnification  to
its directors and officers in respect of claims,  actions,  suits or proceedings
based  upon,  arising  from,  relating to or by reason of the fact that any such
director or officer  serves or served in such  capacity  with  Omnicom or at the
request  of Omnicom  in any  capacity  with any other  enterprise,  and  permits
Omnicom to  indemnify  others  and to advance  expenses  to the  fullest  extent
permitted by law.

     Insofar as indemnification for liabilities arising under the Securities Act
may be  permitted  to  directors,  officers  or persons  controlling  Omnicom or
Holdings  pursuant to the foregoing  provisions,  Omnicom and Holdings have been
informed that in the opinion of the SEC such  indemnification  is against public
policy as expressed in the Securities Act and is therefore unenforceable.

Limitation of Personal Liability of Directors

     Section  102 (b) (7) of the DGCL  permits a  corporation  to include in its
certificate  of  incorporation  a provision  that would  eliminate a  director's
monetary  liability  for  breaches of his  fiduciary  duty in a lawsuit by or on
behalf of the corporation or in an action by  stockholders  of the  corporation,
provided  that such  provision  may not  eliminate  or limit the  liability of a
director (i) for any breach of the director's duty of loyalty,  (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) for unlawful payments of dividends or stock purchases or
redemptions,  or (iv) for any  transaction  from which the  director  derived an
improper personal benefit.  The Holdings  Certificate  contains such a provision
providing for the limitation of liability of directors for monetary  damages for
breach of fiduciary  duty as a director to the fullest  extent  permitted by the
DGCL.

     Section  402(b) of the NYBCL provides that a  corporation's  certificate of
incorporation  may contain a provision  eliminating  or  limiting  the  personal
liability of directors to the  corporation or its  shareholders  for damages for
any breach of duty in such capacity. However, no such provision can eliminate or
limit  (i)  the  liability  of  any  director  if  a  judgment  or  other  final
adjudication  adverse to such director  establishes that such director's acts or
omissions  were in bad faith,  or involved  intentional  misconduct or a knowing
violation  of law, or that the  director  personally  gained in fact a financial
profit or other  advantage to which such  director  was not legally  entitled or
that the director's  acts violated  certain  provisions of the NYBCL or (ii) the
liability of any director for any act or omission  prior to the adoption of such
a provision in the certificate of incorporation.

     The  Omnicom  Certificate  provides  that no director  shall be  personally
liable to Omnicom or any of its  shareholders for damages for any breach of duty
as a director,  except for  liability  resulting  from a judgment or other final
adjudication  adverse to the  director (i) for acts or omissions in bad faith or
which involve intentional misconduct or a knowing violation of the law, (ii) for
any  transaction  from which the  director  derived a financial  profit or other
advantage to which the director was not legally entitled, or (iii) under Section
719 of the NYBCL.

                                 LEGAL MATTERS

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Board of Directors
Chiat/Day Holdings, Inc.

     We have audited the accompanying  consolidated  balance sheets of Chiat/Day
Holdings, Inc. and Subsidiaries as of October 31, 1994 and 1993, and the related
consolidated statements of operations,  stockholders' equity (deficit), and cash
flows for each of the three years in the period ended  October 31,  1994.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion,  the financial statements referred to above present fairly,
in all  material  respects,  the  consolidated  financial  position of Chiat/Day
Holdings,  Inc.  and  Subsidiaries  as of  October  31,  1994 and 1993,  and the
consolidated  results of their  operations  and their cash flows for each of the
three years in the period ended  October 31, 1994 in conformity  with  generally
accepted accounting principles.

     The  accompanying  consolidated  financial  statements  have been  prepared
assuming the Company will continue as a going  concern.  As discussed in Note 1,
the Company's debt under its Senior Note and Senior  Subordinated  Note totaling
$18,750,000  is due in  1995,  which  combined  with  its  working  capital  and
stockholders'  deficits at October 31, 1994, raises  substantial doubt about the
Company's ability to continue as a going concern.  Management's plans as to this
matter are  discussed  in Note 1. The  financial  statements  do not include any
adjustments that might result from the outcome of this uncertainty.

                   CHIAT/DAY HOLDINGS, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  Summary Of Significant Accounting Policies:

Line Of Business:

      Chiat/Day  Holdings,  Inc.  (the  "Company")  is a  holding  company  that
directly or  indirectly  owns 100% of the common stock of  companies  (including
Chiat/Day inc.  Advertising  ["Advertising"]  and Venice  Holdings Pty.  Limited
["Mojo"]) that  collectively  are known as "Chiat/Day"  (see Notes 2 and 8). The
Company's principal line of business includes planning and creating  advertising
campaigns  for clients,  placing ads with various media  (including  television,
radio, newspaper and magazines),  and providing marketing  consultation,  market
research and production  services.  Chiat/Day also provides public relations and
direct  marketing  services.  The Company's  clients operate in a broad range of
product industries  throughout the world. Credit is extended to clients based on
an evaluation of each client's financial condition,  and generally collateral is
not required.  Credit losses,  if any, have been  generally  provided for in the
financial   statements   and  have   been   consistently   within   management's
expectations.

Basis Of Presentation:

      The Company's consolidated financial statements have been presented on the
basis that the Company will continue as a going concern,  which contemplates the
realization of assets and the  satisfaction  of liabilities in the normal course
of  business.  As  discussed  in Note 5, the  Company's  Senior  Note and Senior
Subordinated Notes are due in 1995.

      In February 1995 the Company reached an agreement in principal to sell the
assets and assign the  liabilities of its businesses  (see Note 10). If the sale
does  not  occur,  the  Company  will  have  to  pursue  alternative   financing
arrangements to meet its current debt obligations.

   
      Based upon discussions held with prospective lending  institutions in late
1994 and early 1995,  management  believes that the refinancing of the Company's
outstanding  debt  obligations  and/or  additional  equity  financing  would  be
obtainable if necessary,  although no assurances can be given. If such financing
were  obtained,  given  the  Company's  historical  increases  in cash  and cash
equivalents  and its ability to manage its negative  working  capital  position,
management  believes that the Company would  continue as a viable going concern.
    

Principles Of Consolidation:

      The consolidated  financial statements include the accounts of the Company
and all of its  subsidiaries.  All  significant  intercompany  transactions  and
balances have been eliminated.

Fees, Commissions and Costs:

      The principal sources of advertising revenues are commissions and fees for
the production and placement of  advertisements  in television,  radio and print
media.  Revenue earned from television and radio media is recognized on the date
of broadcast.  Revenue earned from advertising production is recognized as costs
are  incurred.  Generally,   commission  revenue  earned  from  print  media  is
recognized  on the space  closing date (the date upon which the  advertiser  has
made a binding  commitment to the  publication to run an  advertisement)  of the
related publications.

   
      Generally,  revenue is billed and earned in  accordance  with  contractual
provisions.  For the  Company's  contract  with its major  client,  Nissan Motor
Corporation ("Nissan"), commissions are billable on a sliding scale subject to a
maximum  annual  amount for 1994 and 1993 only.  As of October 31, 1994 and 1993
under both contracts,  the Company has recognized as revenue  commissions earned
of 78% of the maximum  allowable for the contract  periods April 1, 1994 through
March 31, 1995 and April 1, 1993 through March 31, 1994.

      Nissan  accounted for 41%, 39% and 38% of total revenue in 1994,  1993 and
1992, respectively. Infiniti, a division of Nissan, accounted for 14% and 10% of
total revenues in 1994 and 1993, respectively.
    

      Revenues  from  other  sources,  including  public  relations  and  direct
marketing,  are primarily derived from fees for services  rendered.  Fee revenue
earned from these sources is  recognized as services are rendered.  Salaries and
other agency costs are generally expensed as incurred.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1.  Summary Of Significant Accounting Policies, Continued:

       
Fixed Assets:

      Depreciation and amortization are provided over the estimated useful lives
of the assets using primarily the straight-line  method for financial  reporting
purposes  and  accelerated  depreciation  methods  for tax  reporting  purposes.
Estimated useful lives of these assets are as follows:

       Furniture and fixtures ..........................    5-10 years
       Office equipment ................................    5-10 years
       Leasehold improvements ..........................    Lease term

      Gains and losses on sales and  retirements  are  reflected in Other income
(expense).  Improvements  which  increase  the useful  lives of fixed assets are
capitalized.  Maintenance,  repairs  and  minor  replacements  are  expensed  as
incurred.

Foreign Currency Translation:

      The  Company   translates   the   financial   statements  of  its  foreign
subsidiaries  in  accordance  with the  provisions  of  Statement  of  Financial
Accounting  Standards  ("SFAS") No. 52. Assets and  liabilities  reported in the
consolidated  balance  sheets  have  been  translated  at the  current  rates of
exchange as of October 31, 1994 and 1993.  Revenues and expenses reported in the
consolidated  statements of operations  have been  translated  using the average
exchange rates during 1994,  1993 and 1992.  Resulting  translation  adjustments
have been  excluded  from the  consolidated  statements  of  operations  and are
reported in a separate component of stockholders' equity (deficit).

      Gains and losses resulting from foreign currency  transactions are charged
to other income  (expense)  as incurred  and were not material in 1994,  1993 or
1992.

Earnings Per Share:

   
      Primary earnings per share is based upon weighted average number of shares
outstanding  during each year.  Primary  earnings per share  (including EPUs and
EARs) is  provided  for  informational  purposes  only and  does not  intend  to
represent  the  EPUs  or  EARs  as  common  stock  equivalents  pursuant  to the
provisions of APB No. 15. The number of shares used in the computations  were as
follows:

                                          1994           1993           1992
                                          ----           ----           ----
Primary                                 54,188,042    55,534,115     58,115,335
Primary (including EPUs and EARs)      114,536,044    55,534,115     83,443,980

      For the purposes of computing earnings per share (including EPUs and EARs)
for the fiscal year ended  October 31, 1993 the EPUs and EARs were not reflected
in the computation as their inclusion would have been anti-dilutive.
    

Income Taxes:

      Effective November 1, 1993, the Company adopted the provisions of SFAS No.
109 which  requires  recognition  of  deferred  tax assets and  liabilities  for
temporary differences and net operating loss (NOL) and tax credit carryforwards.
Under SFAS No. 109,  deferred income taxes are established  based on enacted tax
rates  expected to be in effect when  temporary  differences  are  scheduled  to
reverse and NOL and tax credit  carryforwards  are expected to be utilized.  The
principle  temporary  differences  relate to  restructuring  costs and  employee
bonuses.  Adoption  of SFAS  No.  109  did not  have a  material  impact  on the
Company's financial position or results of operations.

      For years ended 1993 and 1992 the Company accounted for income taxes under
the requirements of APB Opinion No. 11.

Cash Flows:

      The Company places its temporary cash investments in short-term  financial
instruments and money market funds,  which generally  mature within 90 days. The
Company limits the amount of credit exposure to any one issuer.

      For purposes of reporting cash flows,  the Company  considers  amounts due
from banks  (including  certificates  of deposit and repurchase  agreements) and
commercial  paper with maturities at date of purchase of three months or less to
be cash equivalents.

   
     During 1993, the Company issued 37,463,981 Equity  Appreciation Rights (see
Note 6) upon conversion of $20,425,000 of its Junior Notes (see Note 5).

1.  Summary Of Significant Accounting Policies, Continued:

Restatement:

      In  connection  with the  proposed  acquisition  by Omnicom  (Note 10) the
accompanying  financial  statements  have been restated in  accordance  with SEC
Regulation S-X.  Accordingly,  redeemable  preferred stock (Note 5) is no longer
presented  as part of  stockholders'  equity and its initial  carrying  value is
being  increased  to  its  redemption  value  by  periodic   accretions  against
accumulated deficit.
    

Reclassifications

providing  advertising  and related  services.  On February 16, 1993  (effective
January 1, 1993), the Company completed the transfer of the stock of its foreign
subsidiary  to FCB  International,  Inc.  ("FCB")  (see Note 8).  The  financial

     The major  components  of the net deferred tax asset as of October 31, 1994
are as follows:

    Deferred tax assets:

        Deferred compensation ...........................           5,835,000

            Net deferred tax asset ......................                --   
                                                                 ============

   
      A full valuation  allowance has been established at both November 1, 1993,
the date of  adoption  of SFAS No. 109 and October 31, 1994 as it is more likely
than  not the  deferred  tax  asset  will not be  realized.  The  change  in the
valuation  allowance of approximately $5.7 million in fiscal 1994 represents the
reduction in the deferred tax asset due to reversal of temporary  differences in
the determination of the Company's current provision.
    

      As of October 31, 1994, for income tax purposes, the Company had state and
foreign net operating loss  carryforwards of approximately $3.1 million and $2.1
million,  respectively,  which will expire during the years 1995-2000. Also, the
Company had $344,000 of AMT credits which can be carried  forward  indefinitely.
U.S. tax rules impose  limitations  on the use of net  operating  losses and tax
credits following  certain changes in ownership (See Note 10).

4. Related-Party Transactions:

   
      In October 1991,  the Company moved into new office  facilities in Venice,
California which it leases from Venice Operating  Corporation ("VOC"), a company
owned by the majority  stockholder and certain members of the Board of Directors
of the Company.  In October 1994, VOC sold its office facilities to an unrelated
third party.  Effective  October 17, 1994 the lease with VOC was  terminated and
the Company entered into a new twenty year lease with six consecutive  five-year
renewal options. The Company was assigned a $3,000,000 promissory note by VOC in
satisfaction  of the  return  of the  Company's  security  deposit  and  accrued
interest  thereon due from VOC. The note bears interest at 10% per annum and all
interest payments are current.  The note is secured by a right of offset against

future  lease  payments.  The  principal  will be paid  to the  Company  when it
achieves  certain  financial  targets or the property is sold, but no later than
October 17,  2014.  The obligor of the  promissory  note is the new owner of the
Venice office facility,  ADS(CA) QRS 11-34, Inc., a California  corporation that
is  managed  by W.P.  Carey & Co. in New York.  W.P.  Carey & Co. is a  publicly
traded Real Estate  Investment  Trust.  In 1994,  1993 and 1992 the Company paid
$2,474,000, $2,056,000 and $2,018,000, respectively, in rent to VOC.
    
       

      The  Company  also  has  consulting,   employment,  non-compete  and  loan
agreements with certain members of the Board of Directors and officers.

5.  Long-Term Debt, Redeemable Preferred Stock and Common
    Stock Subject to Repurchase Obligations, Continued:

      On September 17, 1992 and June 30, 1993,  Advertising amended and restated
its Credit  Agreement  for the Senior  Bank Note  wherein  the banks  originally
agreed to make loans up to an  aggregate  principal  amount of  $42,000,000,  of
which an aggregate principal amount of $20,000,000 was available and outstanding
on September 17, 1992. In addition to amending  certain terms of the Senior Bank
Note, the banks provided an additional $6,000,000 revolving credit facility. The
revolving   credit  facility  was  guaranteed  by  certain  key  executives  and
stockholders  of the Company.  The 1993  amendment  further  modified the Credit
Agreement  to extend the  commitment  reduction  dates and change the  financial
covenants.  $4,200,000  of the  revolving  credit  facility  and the  associated
guarantees expired on October 31, 1993. At October 31, 1994 and 1993, $7,750,000
and $16,000,000, respectively, of the Senior Bank Note was available; $7,750,000
was  outstanding  at October  31, 1994 and no  borrowings  were  outstanding  at
October 31, 1993. In addition,  no amounts were outstanding  under the revolving
credit facility as of October 31, 1994 and 1993.

      In January  1995,  the Senior Bank Note was  assigned to Omnicom (see Note
10). As a result of this assignment,  the available  commitment was increased to
$20,000,000, and the term was extended to December 10, 1995. Interest is payable
monthly  at prime plus 2%.  Loans  made  under the Senior  Bank Note are due and
payable on December 10, 1995.  The Senior Bank Note is secured by  substantially
all assets of Advertising and Holdings' common equity investment in Advertising.
The remaining  $1,800,000  revolving  credit facility and associated  guarantees
expired in May 1995.
    

     In  1992,  certain  terms  of the  Senior  Subordinated  Notes  due in 1995
("Senior  Notes") were amended.  For $5 million of such Notes, the cash interest
rate was capped at 14.25% effective  August 1, 1991.  Interest that increases by
one quarter  percent every six months from August 1, 1991 until the Senior Notes
have been  registered  under the Securities Act of 1993 will be capitalized  and
paid on  redemption,  but no later than August  1995.  The  interest  rate on $6
million of the Senior Notes has been fixed at 13.25% effective August 1, 1991.

   
      In October  1993,  the  maturity  dates of the Junior  Subordinated  Notes
("Junior  Notes")  were  extended  from  July  31,  1995 to July  31,  2005  and
participants  in the Junior  Notes were  offered the  ability to exchange  their
participation in the Junior Notes for participation in a new Equity Appreciation
Rights  Plan  (see Note 6). As a result of  acceptances  of this  proposal,  the
outstanding  principal  and accrued  interest in the Junior Notes was reduced by
$20,425,000 at October 31, 1993 and resulted in an increase to paid-in-capital.
    

      Borrowing  arrangements contain restrictive covenants which require, among
other  things,  the  maintenance  of  minimum  cash  flow  and  working  capital
requirements, and certain limitations on capital expenditures and the payment of
dividends.

   
      At October 31, 1994, the Company was not in compliance  with its financial
covenants;   however,   the   Company   obtained   waivers  for  all  events  of
noncompliance.  The  Company  is  currently  in  compliance  with all  financial
covenants.
    

Redeemable Preferred Stock:

      The  Preferred  Stock has no voting  rights  and does not  participate  in
Common Stock dividends.  The Preferred Stock is entitled to cumulative dividends
equal to 9% of the  liquidation  preference  of shares  held by the Plan if such
amount is paid in cash, or 10% of the  liquidation  preference if such amount is
paid in shares of Preferred Stock, or any combination thereof. In addition,  the
trustees of the Plan have the right to compel the redemption of Preferred  Stock
held by the Plan in an aggregate  amount not to exceed $500,000 per year. In the
event  the  Preferred  Stock  is not  redeemed  within  180  days  from the date
surrendered,  then such surrendered shares shall be entitled to dividends at the
rate of 14% per annum. In 1994, 1993 and 1992,  stock dividends equal to 13,750,
11,272 and 9,290 shares of  Preferred  Stock,  respectively,  were issued to the
Plan.

      In the event of liquidation or sale of substantially  all of the assets of
the Company,  holders of the Preferred Stock will be entitled to receive, before
any distribution to holders of Common Stock, $100 per share plus any accrued but
unpaid  dividends.  The Preferred  Stock may be redeemed,  subject to applicable
law,  at the end of eight  years at the option of the  Company or the holders of
such Preferred Stock, provided that the Senior Bank Note and Senior Subordinated

Notes have been paid in full,  and, at any time at the option of the holder,  to
the extent the shares  sought to be redeemed are  allocated for the benefit of a
Plan  participant  who is entitled to a distribution  of his account  balance in
such Plan. The purchase price for redemption  would be equal to the  liquidation
preference plus any unpaid dividends.  The sale of such Preferred Stock to third
parties will be subject to the right of first refusal by the Company.


   
Class B Common Stock Subject to Repurchase Obligations:

      Restricted  Stock Plan:  In August  1988,  the Board of  Directors  of the
Company approved a restricted stock purchase plan for which  100,000,000  shares
of Class B Common  Stock were  reserved.  These  shares are  offered for sale to
certain  key  employees  and  others  selected  by the Board of  Directors  at a
purchase price to be determined from time to time by the Company.  The shares of
stock  purchased  under  the plan  vest over a  five-year  period of  employment
beginning from the date of purchase.  The plan provides that upon termination of
employment,  vested  shares may be sold back to or  purchased  by the Company at
book value at date of sale.  Non-vested  shares may be sold back to or purchased
by the Company at the lower of the original purchase price or book value at date
of sale. At October 31, 1994, 59,809,695 shares remain unissued.

     Mojo Class B Common Stock:  Pursuant to a Stock Purchase  Agreement entered
into in April 1989,  the  holders of  7,538,160  shares of Class B Common  Stock
(approximately  one-third of which are held by current officers and directors of
the Company) had the right to require the Company to purchase such shares at the
fair market value  thereof.  Although none of the holders  exercised  such right
prior to its  expiration,  pursuant to the Stock Purchase  Agreement the Company
could be deemed to have exercised in January 1995 a right to acquire such shares
at fair market  value as of October 31, 1994 (as  determined  by an  independent
appraiser).   Any  obligation  of  the  Company  to  repurchase  the  shares  is
subordinated  to the  payment  in full of the  Company's  obligations  under the
Senior  Subordinated  Notes  (provided  that  if  payment  is  deferred  due  to
subordination,  interest will accrue on the  repurchase  price at the prime rate
until paid).  Accordingly,  the Company is not currently obligated to repurchase
such shares due to the subordination  provisions.  In addition, the terms of the
Senior  Bank  Note  prohibit  the  repurchase  of Common  Stock by the  Company.
Although no appraisal has been obtained for the purpose of any such  repurchase,
management of the Company believes that the value of the relevant Class B Common
Stock at October 31, 1994 should  approximate  the value being paid with respect
to Class B Common Stock in the Omnicom transactions. (See Note 10.)

       With the  consent  of the  lenders  under the Senior  Bank Note,  765,000
shares  of Mojo  Class B  Common  Stock  were  repurchased  by the  Company  for
approximately $348,000 and was recorded as a reduction of paid- in capital.

Equity Participation Plan:

      Under an equity  participation  plan approved by the Board of Directors of
the  Company in August  1988,  the  Company  may grant up to  50,000,000  equity
participation  units to eligible  participants.  All full-time  employees of the
Company are eligible to be selected as participants in the equity  participation
plan.  Each equity  participation  unit is  equivalent  in value to one share of
Class B Common  Stock and is treated in the same manner as Class B Common  Stock
with respect to its priority in the event of a liquidation.

      Equity  participation  units  awarded under the plan vest over a five-year
period  of  employment  beginning  from  the  date of  award.  Participants  are
entitled,  upon the redemption of equity participation units, to receive payment
in cash  determined by  multiplying  the number of vested  equity  participation
units by the  increase,  if any,  between the book value per unit (as defined in
the plan) as of the date of grant (which is  determined to be zero when the book
value  is  negative)  and the  book  value  per  unit as of the  valuation  date
immediately preceding the date of redemption. As of October 31, 1994, there were
26,591,110 equity  participation  units available for award. In conjunction with
the transaction  described in Note 8, 2,970,000 equity  participation units were
relinquished to the Company.

    Stock Subject to Repurchase Obligations, Continued:

Equity Appreciation Rights Plan:

      Under  an  equity  appreciation  rights  plan  approved  by the  Board  of
Directors of the Company in October 1993, the Company may grant up to 54,084,848
equity   appreciation  rights  to  eligible   participants.   Only  Junior  Note
participants  (as  defined  in the  plan)  are  eligible  to be  awarded  equity
appreciation rights under the plan. Each equity appreciation right is equivalent
in value to one share of Class B Common  Stock and is treated in the same manner
as  Class B  Common  Stock  with  respect  to its  priority  in the  event  of a
liquidation.

      Equity  appreciation  rights  awarded  under the plan are 41.27% vested in
each participant on the date of award except for certain  participants  that are
100%  vested on the date of award.  Participants  not 100% vested at the date of
award become fully vested 21 months from October 31, 1993 based upon  conditions
stated  in  the  plan.  Upon  redemption  of  the  equity  appreciation  rights,
participants  are entitled to receive  payment in cash determined by multiplying
the number of equity  appreciation  rights by the increase,  if any, between the
book value per unit (as defined in the plan and  determined  to be zero when the
book value is negative) as of October 31, 1993 and the book value per unit as of
the valuation date immediately  preceding the date of redemption.  As of October
31, 1994, there were 36,939,112 equity appreciation rights outstanding.
    

6.  Stockholders' Equity:

Common Stock:

   
      The Class A and Class B Common Stock are alike in all respects except that
the Class A Common  Stock has  certain  registration  and  preferential  rights,
including  the  right to  receive  additional  shares,  and to  approve  certain
transactions.  Holders of Class A Common Stock also are entitled to receive,  in
consideration  for and upon payment of an amount equal to the par value thereof,
additional shares of Class A Common Stock in the event that additional shares of
Class B Common  Stock or equity  participation  units are  issued or  granted in
connection  with  dilutive  transactions  as defined in the  Company's  restated
certificate  of  incorporation,  Class B Common Stock is also subject to certain
repurchase  obligations (see Note 5). In addition,  the Chiat/Day Profit Sharing
and  401(k)  Plan (the  "Plan")  (see Note 7) is  entitled  to  receive,  for no
consideration, additional Class B Common Stock in the event of certain issuances
of Common  Stock to the  majority  stockholder.  At  October  31,  1994,  13,434
additional shares of Class A Common Stock are entitled to be received by current
Class A stockholders due to anti-dilution provisions.

      In addition, during 1993, the Company repurchased 73,832 shares of Class A
Common  Stock  from   non-management   investors  for  $0.01  per  share.  These
repurchases  were pursuant to the Management  Stock Purchase  Agreement  entered
into in July 1989. This agreement  provides for the repurchase of Class A Common
Stock, originally purchased by non-management  investors, in the event EPUs held
by management are forfeited or redeemed under the equity participation plan. The
repurchase  price under the agreement is the greater of par value ($0.01) or the
increase in both value per share from the date of issuance to the date such EPUs
are forfeited or redeemed.
    

7.  Employee Benefit Plans:

      Effective  November 1, 1990,  the Chiat/Day  inc.  Advertising  Employees'
Profit  Sharing and Pre-Tax  Savings  Investment  Plan (the  "401(k)  Plan") was

stock with a  liquidation  value of $450,000 for the  obligation  related to the
fiscal year ended October 31, 1992. The Company has certain future fixed minimum
contributions  of  $525,000,  in stock and cash,  to the Plan for  fiscal  years
ending October 31, 1995 to October 31, 2000.

8.  Disposition Of Foreign Subsidiary:

   
      On February 16, 1993 (effective  January 1, 1993),  the Company  completed
the transfer of the stock of its foreign subsidiary to FCB for no consideration.
Concurrent with the transfer of shares to FCB, the Company  exercised its option
to acquire  $10,350,000  of debt owed to the bank by the foreign  subsidiary for
$700  and  agreed  to  accept  from  FCB,  in full  satisfaction  of such  debt,
$1,380,000  plus future  contingent  payments up to a maximum of $3,450,000.  In
1994, the Company received $653,000 from FCB in contingent  payments.  2,970,000
Equity  Participation  Units were relinquished in accordance with the provisions
of the plan.

      The  contingent  payments  are based upon the revenue  performance  of the
foreign  subsidiary under FCB's ownership and upon the ability of FCB to utilize
Australian tax loss  carryforwards,  all as specified in the debt  restructuring
deed  between  the  Company  and FCB.  Under the debt  restructuring  deed,  all
contingent  revenue and tax loss carryforward  payments are scheduled to be made
by February 26, 1996. All contingent payments made by FCB are recorded as income
by the Company when received.

      The  Company  recorded  a  gain  of  $3,504,000  in  fiscal  1993  on  the
disposition of the foreign  subsidiary  primarily as a result of the recognition
of the accumulated translation adjustment related to such operation.
    

       

      The financial results as of and for the two months ended December 31, 1992
and the year ended October 31, 1992 are summarized as follows:

                                                     1993               1992

9.  Commitments And Contingencies:

Litigation:

      The Company is involved in legal  actions  arising in the normal course of
business.  After taking into  consideration  legal counsel's  evaluation of such
actions,  management  is of the  opinion  that  their  outcome  will  not have a
material effect on the Company's  consolidated  financial position or results of
operations.

9.  Commitments And Contingencies, Continued:

      On October  26,  1992 and  November  20,  1992,  the  Company  settled two
lawsuits which were filed in 1990 related to real estate matters.  The aggregate
cost of such  settlements  was  $6,246,000.  In 1992, the Company  recognized an
incremental charge of $3,200,000  related to these lawsuits.  Adequate provision
for the balance of the settlements was made in prior years.

Leases:

   
      A one-time restructuring charge of $25,848,000 was recorded in fiscal 1993
relating  to  costs  associated  with  certain  real  estate  operating  leases.
Effective  November 1, 1993 the Company entered into a new real estate operating
lease in New York that will enable it to significantly  reduce its future rental
expense through a reduction in total amount of space leased. The Company remains
as the primary  lessee on its old New York lease  through  December 31, 1997. It
has currently sublet  approximately  85% of the space through the lease term and
is actively  seeking to sublet the remaining  space.  $14,802,000  of the charge
relates to the future  cash  rental  obligations,  net of  probable  anticipated
sublease  income,  and  $3,252,000  relates to the write-off of fixed assets and
leasehold improvements.

      In fiscal 1993 the Company  entered into  agreements  to assign its lease,
effective  January 1, 1994,  for the 320 Hampton Drive  facility to an unrelated
third party in order to  consolidate  operations  into one  facility at 340 Main
Street.  All fixed assets and  leasehold  improvements  related to such facility
were written off in 1993.  Alterations to the 340 Main Street property were made
in order to facilitate the  consolidation  into one facility.  $5,122,000 of the
restructuring  charge  related to the  write-off of leasehold  improvements  and
fixed assets at both  facilities as a result of the  consolidation  and $940,000
related to cash obligations incurred in connection with the lease assignment and
moving and related costs incurred in connection with the consolidation  into one
location.  The  remaining  balance  of the  restructuring  charge of  $1,732,000
represents a reserve for future cash rental obligations in excess of anticipated
probable sublease income for other property leased in California.

      The Company leases  facilities and equipment under various operating lease
agreements  expiring  at various  dates  through the year 2015.  Certain  leases
require  payment of expenses  under  escalation  clauses.  The aggregate  future
minimum base rents under terms of noncancellable  operating  leases,  reduced by
rent to be received from existing noncancellable subleases, are as follows:

Years ending October 31,            Gross rent     Sublease Income       Total

      Rental  expense  for  leases was  $5,580,000,  $9,422,000  and  $9,140,000
(excluding rental expense related to the Company's foreign  subsidiary  disposed
of in 1993) for the years ended October 31, 1994, 1993 and 1992, respectively.


10.  Subsequent Event:

      On  May  11,  1995,   the  Company   signed  an  agreement   whereby  TBWA
International Inc., a wholly-owned subsidiary of Omnicom Group Inc. ("Omnicom"),
will acquire the assets of the Company's businesses and assume substantially all
of its liabilities in exchange for Omnicom common stock. The sale is conditional
on the  registration  of the Omnicom common stock on Form S-4,  clearance by the
appropriate  governmental  agencies,  approval  by a majority  of the  Company's
stockholders and certain other  conditions.  The sale is anticipated to close by
August 1995.

     1) The consolidated  condensed interim financial statements included herein
have  been  prepared  by  Holdings,  without  audit,  pursuant  to the rules and
regulations of the Securities and Exchange  Commission.  Certain information and
footnote  disclosures  normally  included in  financial  statements  prepared in
accordance with generally accepted accounting  principles have been condensed or
omitted pursuant to such rules and regulations,  although Holdings believes that
the disclosures are adequate to make the information presented not misleading.

     2) These statements reflect all adjustments  consisting of normal recurring
accruals  which,  in  the  opinion  of  management,  are  necessary  for a  fair
presentation of the information  contained  therein.  It is suggested that these
consolidated  condensed  financial  statements be read in  conjunction  with the
consolidated financial statements and notes thereto included in Holdings' latest
fiscal report.

     3)  Results of  operations  for the  interim  periods  are not  necessarily
indicative of annual results.

     4) Primary  earnings per share is based upon the weighted average number of
shares  outstanding during each year. Primary earnings per share (including EPUs
and EARs) is provided  for  informational  purposes  only and does not intend to
represent  the  EPUs  or  EARs  as  common  stock  equivalents  pursuant  to the
provisions of APB No. 15. The number of shares used in the computations  were as
follows:

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers.

     The Registrant's Certificate of Incorporation contains a provision limiting
the  liability  of  directors  (except  for  approving  statutorily   prohibited
dividends,  share  repurchases  or  redemptions,   distributions  of  assets  on
dissolution or loans to directors) to acts or omissions in bad faith,  involving
intentional  misconduct  or a knowing  violation  of the law,  or  resulting  in
personal gain to which the director was not legally  entitled.  The Registrant's
By-Laws  provide  that an officer or director  will be  indemnified  against any
costs or  liabilities,  including  attorneys fees and amounts paid in settlement
with the  consent of the  registrant  in  connection  with any claim,  action or
proceeding to the fullest extent permitted by the New York Business  Corporation
Law.

     Section  722(a) of the New York  Business  Corporation  Law provides that a
corporation  may  indemnify  any officer or director,  made or  threatened to be
made, a party to an action other than one by or in the right of the corporation,
including  an  action  by or in the  right  of any  other  corporation  or other
enterprise,  which any  director  or  officer of the  corporation  served in any
capacity at the request of the corporation, because he was a director or officer
of the corporation,  or served such other corporation or other enterprise in any
capacity,  against judgments,  fines,  amounts paid in settlement and reasonable
expenses,  including  attorneys'  fees  actually and  necessarily  incurred as a
result of such action, or any appeal therein, if such director or officer acted,
in good faith,  for a purpose which he  reasonably  believed to be in, or in the
case of service for any other corporation or other  enterprise,  not opposed to,
the best interests of the corporation and, in criminal actions, in addition, had
no reasonable cause to believe that his conduct was unlawful.

     Section  722(c) of the New York  Business  Corporation  Law provides that a
corporation  may  indemnify  any officer or director  made,  or threatened to be
made,  a party to an action by or in the right of the  corporation  by reason of
the fact that he is or was a director of the  corporation,  or is or was serving
at the  request  of the  corporation  as a  director  of  officer  of any  other
corporation of any type or kind, or other  enterprise,  against  amounts paid in
settlement  and  reasonable  expenses,  including  attorneys'  fees actually and
necessarily incurred by him in connection with the defense or settlement of such
action,  or in connection  with an appeal  therein,  if such director or officer
acted, in good faith,  for a purpose which he reasonably  believed to be in, or,
in the case of service for another corporation or other enterprise,  not opposed
to, the best interests of the  corporation.  The corporation  may not,  however,
indemnify any officer or director pursuant to Section 722(c) in respect of (1) a
threatened  action,  or a pending action which is settled or otherwise  disposed
of, or (2) any claim,  issue or matter as to which such  person  shall have been
adjudged to be liable to the corporation, unless and only to the extent that the
court in which the action was brought or, if no action was brought, any court of
competent jurisdiction,  determines in its discretion, that the person is fairly
and  reasonably  entitled to indemnity  for such portion of the  settlement  and
expenses as the court deems proper.

     Section  723 of the New York  Business  Corporation  Law  provides  that an
officer or director  who has been  successful  on the merits or otherwise in the
defense of a civil or criminal  action of the character set forth in Section 722
is entitled to indemnification as permitted in such section.  Section 724 of the
New York Business  Corporation Law permits a court to award the  indemnification
required by Section 722.

     The Registrant has entered into  agreements with its directors to indemnify
them for  liabilities  or costs  arising out of any alleged or actual  breach of
duty, neglect,  errors or omissions while serving as a director.  The Registrant
also  maintains  and  pays  premiums  for  directors'  and  officers'  liability
insurance policies.


Item 21.  Exhibits and Financial Statement Schedules.

     (a) See Exhibit Index

     (b) See the  financial  statement  schedules  included in Omnicom's  Annual
Report  on  Form  10-K  incorporated  in this  Prospectus/Information  Statement

<PAGE>

Item 22.  Undertakings.

       
   
     (a) The  undersigned  Registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is  incorporated  by  reference  in this  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.

     (b) The undersigned  Registrant hereby undertakes as follows: that prior to
any public  reoffering of the securities  registered  hereunder through use of a
prospectus  which is a part of this  Registration  Statement,  by any  person or
party who is deemed to be an underwriter within the meaning of Rule 145(c) under
the Securities Act, the issuer  undertakes that such reoffering  prospectus will
contain the  information  called for by the  applicable  registration  form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other Items of the applicable form.

     (c) The  Registrant  undertakes  that  every  prospectus  (i) that is filed
pursuant to paragraph (b) immediately  preceding,  or (ii) that purports to meet
the  requirements of section  10(a)(3) of the Act and is used in connection with
an offering of securities  subject to Rule 415 under the Securities Act, will be
filed as a part of an amendment to the  registration  statement  and will not be
used until such  amendment is effective,  and that,  for purposes 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.
    

     (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers or persons  controlling the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against  public policy as expressed in the 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 whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     (e) The undersigned Registrant hereby undertakes to respond to requests for
information  that is incorporated  by reference into the Prospectus  pursuant to
Items 4, 10(b),  11 or 13 of this Form,  within one  business  day of receipt of
such  requests,  and to send the  incorporated  documents by first class mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of the responding to the request.

     (f) The undersigned  Registrant  hereby  undertakes to supply by means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the Registration Statement when it became effective.

                       LIQUIDATING TRUST ESCROW AGREEMENT


     LIQUIDATING TRUST ESCROW AGREEMENT, dated ____________, 1995 (the "Escrow
Agreement"), among CHIAT/DAY INC. ADVERTISING, a Delaware corporation
("Advertising"); CHIAT/DAY HOLDINGS, INC., a Delaware corporation ("Holdings");
and David C. Wiener, as Escrow Agent (the "Escrow Agent").

                                  INTRODUCTION

     A. Advertising, Holdings, TBWA International Inc. (the "Purchaser") and
Omnicom Group Inc., a New York corporation ("Omnicom") are parties to a certain
Asset Purchase Agreement dated May 11, 1995 (the "Purchase Agreement"), pursuant
to which the Purchaser acquired the assets and liabilities and the ongoing
businesses of Advertising and Holdings. Pursuant to the Purchase Agreement,
Holdings, Advertising and the Purchaser have entered into an escrow agreement of
even date herewith (the "Omnicom Indemnification Escrow Agreement") to secure
the Purchaser against certain Losses (as more fully set forth in the Purchase
Agreement). There will be created pursuant to the Omnicom Indemnification Escrow
Agreement a "General Escrow Fund" which will consist of two separate and
segregated sub-accounts, the "Stockholders General Escrow Fund" and the
"Rightsholders General Escrow Fund", and a "Special Escrow Fund" which will
consist of two separate and segregated sub-accounts, the "Stockholders Special
Escrow Fund" and the "Rightsholders Special Escrow Fund". The Stockholders
General Escrow Fund and the Stockholders Special Escrow Fund will contain
deposits designated for such account made by or on behalf of the Stockholders.
The Rightsholders General Escrow Fund and the Rightsholders Special Escrow Fund
will contain deposits designated for such account made by or on behalf of the
Rightsholders (as defined below). Terms defined in the Purchase Agreement that
are not otherwise defined herein are used herein with the meanings ascribed to
them therein.

     B. The Purchase Agreement provides that Holdings will liquidate and
dissolve and that, in the course of its expeditious and orderly winding up
process, Holdings shall cause to be created a liquidating trust (hereinafter,
the "Liquidating Trust" and the trustee or trustees thereof, the "Liquidating
Trustee") to act as the representative for Holdings and the Stockholders.

     C. There will also be created, pursuant to this Escrow Agreement, a
"Liquidating Trust Escrow Fund" which shall be available solely to fund and
secure obligations of holders of EARs and EPUs (collectively, the
"Rightsholders") to reimburse the Liquidating Trust for payments made by it in
respect of contingent or other liabilities of Holdings and Advertising, all in
accordance with this Escrow Agreement. The Liquidating Trust Escrow Fund will
contain deposits designated for such fund made by or on behalf of the
Rightsholders pursuant to Section 2.7 of


<PAGE>

the Purchase Agreement. The Liquidating Trust Escrow Fund is expressly not
intended to fund or secure the indemnification obligations of Holdings to the
Purchaser or any other Indemnified Party described in Section 11.2 of the
Purchase Agreement and none of Omnicom, the Purchaser or any other Indemnified
Party shall have any recourse to the Liquidating Trust Escrow Fund or the
Liquidating Trust Escrow Income (as defined below) for any purpose whatsoever.

     D. The Purchase Agreement provides that Advertising shall distribute to the
Rightsholders pro rata in accordance with their interests, the shares of Omnicom
Common Stock, par value $.50 per share ("Omnicom Stock"), received by it
pursuant to the Purchase Agreement, less the shares of Omnicom Stock to be
transferred by Advertising to the General Escrow Fund and the Special Escrow
Fund (pursuant to the Omnicom Indemnification Escrow Agreement) and the
Liquidating Trust Escrow Fund created hereby on behalf of such Rightsholders.
Advertising and the Rightsholders have designated the Escrow Agent (such
designation by Advertising, for itself and on behalf of the Rightsholders, being
made by its execution of this Agreement), as their collective agent in
connection with the administration of this Escrow Agreement, including without
limitation to amend, cancel or extend, or waive the terms of this Escrow
Agreement; to respond to the assertion of any and all claims for indemnification
from the Liquidating Trust Escrow Fund by the Liquidating Trust pursuant to the
terms of this Escrow Agreement and the provisions of the Purchase Agreement, if
any, pertaining thereto; and to receive on their behalf the distributions, if
any, that would otherwise be due to them upon the distribution of all or a
portion of the Liquidating Trust Escrow Fund and Liquidating Trust Escrow Income
as herein provided.

funding of the Liquidating Trust shall be deemed to refer to the Liquidating

(and setting forth the calculations described below), requesting reimbursement

and certifying that such liability has become due and payable. The amount of
funds so requested shall be equal to (x) the total amount of the payment to be

Property then on deposit (before making the required payment). The Escrow Agent
shall provide the Liquidating Trustee with any information requested by it for

shall have any recourse for the payment of any losses or claims of any kind
whatsoever against the Rightsholders or their respective affiliates, nor shall

<PAGE>


     (b) The parties agree that this security interest shall attach as of the
execution of this Escrow Agreement. The parties agree that, for the purpose of
perfecting the Holdings' security interest in the above designated Liquidating
Trust Escrow Fund held by the Escrow Agent pursuant to this Escrow Agreement,
Holdings designates the Escrow Agent to acquire and maintain possession of the
Liquidating Trust Escrow Fund and act as bailee for the Holdings with notice of
the Holdings' security interest in said property under the Uniform Commercial
Code and that possession of the Liquidating Trust Escrow Fund by the Escrow
Agent acknowledges that it holds the Liquidating Trust Escrow Fund for Holdings
for purposes of perfecting the security interest. Advertising and the
Rightsholders, and the Escrow Agent shall take all other actions requested by
Holdings to maintain the perfection and priority of the security interest in the
Liquidating Trust Escrow Fund; provided that the Escrow Agent does not make any
representation or warranty with regard to the creation or perfection, hereunder
or otherwise, of any such security interest, and shall have no responsibility at
any time to ascertain whether or not any security interest exists.

     (c) Holdings shall release the security interest herein granted and the
security interest shall be terminated to the extent of any disbursement of the
Liquidating Trust Escrow Fund hereunder by the Escrow Agent in accordance with
the terms of this Escrow Agreement. Upon final disbursement of the Liquidating
Trust Escrow Fund to the Liquidating Trustee, the Liquidating Trustee shall do
all acts and things reasonably necessary to release and extinguish such security
interest. Advertising on behalf of itself and the Rightsholders, and Holdings on
behalf of itself and the Stockholders, hereby specifically agree that the grant
of this security interest pursuant to this Article III shall not in any way
modify the procedures the parties hereto must follow with respect to the release
of funds from the Liquidating Trust Escrow Fund.

IV.  ESCROW AGENT'S DUTIES AND FEES

     4.1. Duties Limited. The Escrow Agent undertakes to perform only such
duties as are expressly set forth herein. The Escrow Agent shall not be bound
by, or have any responsibility with respect to, any other agreement between any
of the parties (other than an agreement to which the Escrow Agent is a party).
The Escrow Agent shall have no duty or responsibility with regard to any loss or
resulting from the investment, reinvestment, sale or liquidation of the
Liquidating Trust Escrow Fund or Liquidating Trust Escrow Income in accordance
with the terms of this Agreement. The Escrow Agent need not maintain insurance
with respect to the Liquidating Trust Escrow Fund or Liquidating Trust Escrow
Income.

good faith, shall not be liable for any mistake of fact or error of judgment
by it or for any acts or omissions

                                       6

<PAGE>


by it of any kind unless caused by gross negligence or willful misconduct, and
the Escrow Agent may rely, and shall be protected in acting or refraining from
acting, upon any written notice, instruction or request furnished to it
hereunder and believed by it to be genuine and to have been signed or presented
by the proper party or parties; provided that, as set forth below, modification
of this Escrow Agreement shall be signed by all of the parties hereto. The
Escrow Agent is hereby authorized to comply with any judicial order or legal
process which stays, enjoins, directs or otherwise affects the transfer or
delivery of any part of the Liquidating Trust Escrow Fund or Liquidating Trust
Escrow Income or any party hereto and shall incur no liability for any delay or
loss which may occur as a result of such compliance.

     4.3. Good Faith. Advertising on behalf of itself and the Rightsholders, and
Holdings on behalf of itself and the Stockholders, hereby agree to indemnify the
Escrow Agent for, and to hold it harmless against, any loss, liability, expense
(including reasonable attorneys' fees and expenses), third party claim and
demand, incurred by it without gross negligence or bad faith on its part,
arising out of or in connection with its entering into this Escrow Agreement and
the carrying out of its duties hereunder. The Escrow Agent may consult with
counsel of its own choice, and shall have full and complete authorization and
protection for any action taken or suffered by it hereunder in good faith and in
accordance with the opinion of such counsel. The foregoing indemnification shall
survive the resignation of the Escrow Agent or the termination of this Escrow
Agreement.

     4.4. Successor Escrow Agents. The Escrow Agent may resign and be discharged
from its duties or obligations hereunder at any time by giving 30 days' notice
in writing of such resignation to Holdings and Advertising. Holdings and
Advertising, together, shall have the right to terminate the appointment of the
Escrow Agent hereunder by giving to it notice in writing of such termination
specifying the date upon which such termination shall take effect. In either
such event, Holdings and Advertising hereby agree to promptly appoint a
successor escrow agent; if Holdings and Advertising are unable to appoint a
successor Escrow Agent within 25 days after the Escrow Agent's notice of
resignation, the Escrow Agent may petition a court of competent jurisdiction to
appoint a successor. The parties hereto agree that, upon demand of such
successor escrow agent, all property in the Liquidating Trust Escrow Fund and
the Liquidating Trust Escrow Income shall be turned over and delivered to such
successor escrow agent, which thereupon shall become bound by all of the
provisions hereof.

     4.5. Fees and Expenses. The parties agree to pay on an equal basis to the
Escrow Agent reasonable compensation for the services to be rendered by it
hereunder and to pay to or reimburse the Escrow Agent for all reasonable
expenses, disbursements and advances (including reasonable attorneys' fees)

<PAGE>

incurred or made by it in connection with the carrying out of its duties
hereunder. Advertising on behalf of itself and the Rightsholders, and Holdings
on behalf of itself and the Stockholders, agree that the Escrow Agent may deduct
any unpaid fees from the Liquidating Trust Escrow Fund and the Liquidating Trust
Escrow Income prior to the Escrow Agent's distributing any assets in connection
with the termination of the Liquidating Trust Escrow Fund. As security for such
fees and expenses of the Escrow Agent and any and all such losses, liabilities,
expenses and claims incurred by the Escrow Agent in connection with its
acceptance of appointment hereunder, and with performance of the agreements
herein contained, the Escrow Agent is hereby given a lien upon all assets held
by the Escrow Agent hereunder, which lien shall be prior to all other liens upon
or claims against such assets.

     4.6. Taxes. To the extent required by applicable law, the Escrow Agent
agrees to file tax returns on behalf of the Liquidating Trust Escrow Fund, and
pay taxes on the Liquidating Trust Escrow Income, on the basis that the
Liquidating Trust Escrow Fund is a trust that is not a grantor trust. Any such
taxes shall be paid out of the Liquidating Trust Escrow Fund and the Liquidating
Trust Escrow Income. The Escrow Agent shall also file and deliver all
appropriate information returns with respect to the Liquidating Trust Escrow
Income and the payment of such taxes. The Escrow Agent shall make no
disbursement from Liquidating Trust Escrow Fund that would cause the balance of
the Liquidating Trust Escrow Fund to be less than the aggregate taxes due or to
become due on the Liquidating Trust Escrow Income.

     This Escrow Agreement may be amended, superseded or canceled, and any of
the terms or conditions hereof may be waived, only by a written instrument
executed by the parties hereto or, in the case of a waiver, by the party waiving
compliance (or his agent). The failure of any party at any time or times to
require performance of any provision hereof shall in no manner affect the right
of such party at a later time to enforce the same. No waiver of any nature,
whether by conduct or otherwise in any one or more instances, of any provision
hereof, shall be deemed to be, or construed as, a further or continuing waiver
of any such provision or of another provision hereof.

                     Re: Registration Statement on Form S-4
                         ----------------------------------

Gentlemen:

     In our capacity as counsel to Omnicom  Group Inc.,  a New York  corporation
(the  "Company"),  we have been asked to render this opinion in connection  with
Registration  Statement No. 33-60167 on Form S-4 (the "Registration  Statement")
filed by the Company  with the  Securities  and  Exchange  Commission  under the
Securities  Act of 1933,  as  amended,  covering an  aggregate  of up to 600,000
shares of common  stock,  $0.50 par value,  of the Company (the  "Shares") to be
issued in connection with the acquisition by the Company, through its indirectly
wholly-owned subsidiary TBWA International Inc., of the assets and businesses of
Chiat/Day Holdings, Inc. and Chiat/Day inc. Advertising.

     In that connection,  we have examined the Certificate of Incorporation  and
the  By-Laws,  both as amended,  of the  Company,  the  Registration  Statement,
corporate  proceedings  relating to the  issuance of the Shares,  and such other
instruments and documents as we deemed relevant under the circumstances.

     In making the aforesaid examination, we have assumed the genuineness of all
signatures and the conformity to original  documents of all copies  furnished to
us as original or  photostatic  copies.  We have also assumed that the corporate
records  furnished to us by the Company include all corporate  proceedings taken
by the Company to date.

     Based upon and subject to the  foregoing,  we are of the opinion  that when
issued in accordance with the Acquisition  Agreement,  the Shares will have been
legally  issued and be fully  paid and  non-assessable  shares of common  stock,
$0.50 par value, of the Company.

     We hereby  consent  to the use of our  opinion  as  herein  set forth as an
exhibit  to the  Registration  Statement  and to the use of our name  under  the
caption "Legal Matters" in the Prospectus/Information  Statement forming part of
the Registration Statement.

                                                        Very truly yours,

                                                        DAVIS & GILBERT



                                                                   Exhibit 23.1

                   CONSENT OF INDEPENDENT PUBLIC ACCOUNTANTS

     As independent public  accountants,  we hereby consent to the incorporation

1994 included in Omnicom Group Inc.'s Form 10-K for the year ended  December 31,
1994 and to all references to our Firm included in this registration statement.

                       Consent of Independent Accountants
