                    NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
   
                          To Be Held On May 30, 1996
    

To The Shareholders of
Ketchum Communications Holdings, Inc.:

   
     A Special Meeting of the Shareholders of Ketchum  Communications  Holdings,
Inc., a Pennsylvania corporation  ("Ketchum"),  will be held on May 30, 1996, at
5:00 p.m.  (local time), at the offices of Ketchum,  Six PPG Place,  Pittsburgh,
Pennsylvania 15222, to consider and vote upon the following matters described in
the accompanying Prospectus/Information Statement:
    

     1.   To  consider  and act upon the  approval of an  Agreement  and Plan of
          Merger  (the  "Merger  Agreement")  pursuant  to which a  wholly-owned
          subsidiary of Omnicom Group Inc., a New York corporation  ("Omnicom"),
          will be  merged  with  and  into  Ketchum,  such  that  the  surviving
          corporation  of such  merger  shall be a  wholly-owned  subsidiary  of
          Omnicom and each outstanding share of capital stock of Ketchum will be
          converted  into the right to receive a certain  amount of common stock
          of  Omnicom,   all  as  more  fully  described  in  the   accompanying
          Prospectus/Information Statement; and

     2.   To  consider  and act upon the  approval of an Escrow  Agreement  (the
          "Escrow  Agreement") to be entered into in connection  with the Merger
          Agreement  and  the   appointment   of  Paul  H.  Alvarez  as  Ketchum
          Shareholder Representative, and Edward L. Graf as alternate, to act as
          the collective  agent of the holders of Ketchum common stock under the
          terms of the  Escrow  Agreement,  all as more fully  described  in the
          accompanying Prospectus Information Statement; and

     3.   To consider and act upon any other  business  which may properly  come
          before the Special Meeting or any adjournment thereof.

   
     Only  holders of record as of the close of  business  on April 15,  1996 of
common stock, stated value $0.005 per share, of Ketchum ("Ketchum Common Stock")
and of Series A Preferred Stock, $100 par value, of Ketchum ("Ketchum  Preferred
Stock") are entitled to notice of and to vote at the Special Meeting.
    

     The  affirmative  votes of the holders of a majority of the Ketchum  Common
Stock,  voting as a class,  and of the holders of all of the  Ketchum  Preferred
Stock,  voting as a class,  are required to approve the Merger Agreement and the
transactions  contemplated  thereby.  The  affirmative  vote of the holders of a
majority of the voting power  represented by the  outstanding  shares of Ketchum
Common Stock and Ketchum Preferred Stock,  voting together as a single class, is
necessary to approve the Escrow  Agreement  and the  appointment  of the Ketchum
Shareholder Representative.  None of the proposals shall become effective unless
all of the proposals are adopted by the requisite  vote of the  shareholders  of
Ketchum.

      The Board of Directors of Ketchum believes that the foregoing transactions
are fair to, and in the best  interests  of,  Ketchum  and the  shareholders  of
Ketchum,  and recommends that the  shareholders of Ketchum vote FOR the approval
of the Merger  Agreement  and FOR the approval of the Escrow  Agreement  and the
appointment of the Ketchum Shareholder Representative.  Shareholders who dissent
from the Merger in accordance with the Pennsylvania  Business Corporation Law, a
copy  of  which  appears  as  Annex  1 to  the  attached  Prospectus/Information
Statement,  shall have the right to seek  appraisal  of their  capital  stock of
Ketchum.

   
     As of April 15,  1996,  directors  and  executive  officers of Ketchum as a
group owning  approximately  56.70% of Ketchum  Common Stock,  have expressed an
intention  to vote in favor of the  transactions  contemplated  herein;  and the
Trustee of the Ketchum 401(k) Profit Sharing Plan, as the sole holder of Ketchum
Preferred Stock, has expressed an intention to vote in favor of the transactions
contemplated  herein.  Accordingly,  the proposals  can be approved  without the
affirmative vote of any other shareholder of Ketchum.
    

             WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED

                                     (a)  a  proposal   to  approve  the  Merger
                                          Agreement    and   the    transactions
                                          contemplated    thereby,     including
                                          without   limitation   the  Merger  of
                                          OmniSub with and into Ketchum pursuant
                                          to the  Merger  Agreement,  such  that
                                          Ketchum   will   be   the    surviving
                                          corporation  of such  Merger  and will
                                          become a  wholly-owned  subsidiary  of
                                          Omnicom,  and each  share  of  Ketchum
                                          Stock will be converted into the right
                                          to receive  shares of  Omnicom  Common
                                          Stock, as more fully described herein.
                                                  
                                     (b)  a  proposal   to  approve  the  Escrow

                                          contemplated  thereby,  and to appoint
                                          Paul  H.   Alvarez   as  the   Ketchum
                                          Shareholder Representative, and Edward
                                          L. Graf as alternate, to act on behalf
                                          of  the  Ketchum  Common  Shareholders
                                          under   the   terms   of  the   Escrow
                                          Agreement; and
                                               
                                     (c)  such other  proposals  as may properly
                                          be brought before the Special Meeting.

                                   None of these  matters will become  effective
                                   unless all of the  proposals  are  adopted by
                                   the   requisite    votes   of   the   Ketchum
                                   Shareholders.

   
Vote Required ..................   Pursuant to Pennsylvania law, the approval of
                                   the  Merger  Agreement  and the  transactions
                                   contemplated   thereby   will   require   the
                                   affirmative   votes  of  the   holders  of  a
                                   majority of the Ketchum Common Stock,  voting
                                   as a class,  and of the holders of a majority
                                   of the Ketchum  Preferred Stock,  voting as a
                                   class;   and  the   approval  of  the  Escrow
                                   Agreement and the  appointment of the Ketchum
                                   Shareholder  Representative,   or  any  other
                                   proposals as may  properly be brought  before
                                   the  Special   Meeting,   will   require  the
                                   affirmative vote of the holders of a majority
                                   of  the  voting  power   represented  by  the
                                   outstanding  shares of Ketchum  Common  Stock
                                   and Ketchum Preferred Stock,  voting together
                                   as  a  single  class.   However,  the  Merger
                                   Agreement imposes, as an additional condition
                                   to the vote required, that the Trustee of the
                                   Ketchum   401(k)  Profit  Sharing  Plan  (the
                                   "Ketchum  Profit  Sharing  Plan")  shall have
                                   voted all the shares of Ketchum  Stock  owned
                                   by the Ketchum  Profit  Sharing Plan in favor
                                   of the Merger.

                                   As  of  the  Record   Date,   directors   and
                                   executive   officers  of  Ketchum   owned  an
                                   aggregate of 203,458 shares of Ketchum Common

                                   Stock, representing 56.70% of the outstanding
                                   Ketchum Common Stock as of such date; and the
                                   Ketchum  Profit  Sharing Plan owned of record
                                   an  aggregate  of  6,282  shares  of  Ketchum
                                   Preferred  Stock,  representing  100%  of the
                                   outstanding  Ketchum  Preferred  Stock  as of
                                   such date.  Each of such  individuals and the
                                   Trustee of the Ketchum  Profit  Sharing  Plan
                                   has  expressed  an intention to vote in favor
                                   of the various  proposals.  Accordingly,  the
                                   proposals   can  be   approved   without  the
                                   affirmative   vote  of  any   other   Ketchum
                                   Shareholders.

    
              Description of Certain Terms of the Merger Agreement

The Proposed Merger ............   Subject  to  the   approval  of  the  Ketchum
                                   Shareholders of the Merger Agreement, OmniSub
                                   will be merged  with and into  Ketchum.  As a
                                   result of the Merger, the business of Ketchum
                                   will be operated as a wholly-owned subsidiary
                                   of Omnicom.

Conversion of Ketchum
Stock ..........................   If the Merger is  consummated,  each share of
                                   Ketchum  Common Stock will be converted  into
                                   shares of Omnicom  Common  Stock,  based upon
                                   the "Common Stock  Conversion  Price" and the
                                   "Market  Value" of the Omnicom  Common Stock.
                                   If the Merger is  consummated,  each share of
                                   Ketchum  Preferred  Stock  will be  converted
                                   into shares of Omnicom  Common  Stock,  based
                                   upon the "Preferred Stock  Conversion  Price"
                                   of  $1,000  and  the  "Market  Value"  of the
                                   Omnicom   Common   Stock.   See  "The  Merger
                                   Agreement   and  the   Merger--   the  Merger
                                   Agreement -- Conversion Prices".

   
                                   The actual  "Common Stock  Conversion  Price"
                                   will  be  an  amount   per  share   equal  to
                                   $44,940,000 divided by the outstanding number
                                   of shares of Ketchum Common Stock at the time
                                   the  Merger is  legally  effective  under the
                                   laws of the Commonwealth of Pennsylvania (the
                                   "Effective   Time"   of  the   Merger);   the
                                   "Preferred Stock  Conversion  Price" has been
                                   set  at  the  liquidation  preference  of the
                                   Ketchum  Preferred  Stock and is  fixed.  The
                                   total  number  of shares  of  Omnicom  Common
                                   Stock   to   be   issued   to   the   Ketchum
                                   Shareholders   based  upon  such   Conversion
                                   Prices  will  be  dependent  on  the  "Market
                                   Value" of the  Omnicom  Common  Stock,  which
                                   will  be  determined  by the  average  of the
                                   closing  prices  per  share  of  the  Omnicom
                                   Common  Stock on the New York Stock  Exchange
                                   during the 20 consecutive trading days ending
                                   three business days immediately  prior to the
                                   date  of the  Special  Meeting.  Accordingly,
                                   although the actual conversion exchange rates
                                   cannot be  calculated  as of the date of this
                                   Prospectus/Information     Statement,    such
                                   conversion  exchange  rates  will be known by
                                   the date of the  Special  Meeting and will be
                                   available to the attendees thereof.

                                   In order to make  certain  estimates  in this
                                   Prospectus/Information  Statement relating to
                                   the  consideration  to be paid to the Ketchum
                                   Shareholders, it has been assumed that at the
                                   Effective Time of the Merger,  358,818 shares
                                   of Ketchum Common Stock will be  outstanding,
                                   which  would   result  in  a  "Common   Stock
                                   Conversion  Price"  of  $125.24  per share of
                                   Ketchum Common Stock.  Assuming then that the
                                   Market Value of the Omnicom Common Stock were
                                   $41 (which was the closing price per share of
                                   Omnicom  Common  Stock on the New York  Stock

                                   Exchange  on the last full  trading day prior
                                   to the  execution  and delivery of the Merger
                                   Agreement),  each  share  of  Ketchum  Common
                                   Stock  would be  converted  into the right to
                                   receive 3.05 shares of Omnicom  Common Stock,
                                   and each  share of  Ketchum  Preferred  Stock
                                   would be converted  into the right to receive
                                   24.39 shares of Omnicom Common Stock.

                                   The  closing  of the  Merger  Agreement  (the
                                   "Closing")  has  been  scheduled  for May 31,
                                   1996,  the day after the date of the  Special
                                   Meeting; however, this Closing may be delayed
                                   beyond May 31, 1996 if all  conditions of the
                                   Merger have not been  satisfied  or waived by
                                   such date. There will be no adjustment to the
                                   Conversion    Prices    if    this    occurs,
                                   notwithstanding  that the actual value of the
                                   Omnicom Common Stock could fluctuate  between
                                   the date of the Special  Meeting and the date
                                   of   the   Closing.    At   the   time   this
                                   Prospectus/Information   Statement  is  being
                                   mailed to the Ketchum  Shareholders,  Omnicom
                                   has no reason to believe that the date of the
                                   Closing   will   not  be  May  31,   1996  as
                                   scheduled.

                                   Common Shareholders are required to indemnify
                                   Omnicom and its  affiliates  against  certain
                                   losses and damages  arising  under the Merger
                                   Agreement.  Losses and damages may arise as a
                                   result of (i) the inaccuracy or breach of any
                                   representation  or  warranty  or  covenant of
                                   Ketchum contained in the Merger Agreement, or
                                   the  breach  of  or  failure  by  Ketchum  to

Conditions to the Merger .......   Consummation of the Merger is contingent upon
                                   satisfaction of certain conditions, including
                                   without  limitation,  the  SEC's  not  having
                                   objected to Omnicom's treatment of the Merger
                                   as  a  pooling-of-interests   for  accounting
                                   purposes,  the Registration  Statement having
                                   been  declared  effective  by the SEC and not
                                   subject to a stop order,  or threatened  stop
                                   order;   the  Omnicom   Common   Stock  being
                                   registered  thereunder  having been  approved
                                   for  listing on the New York Stock  Exchange;
                                   holders of fewer  than 3% of the  outstanding
                                   shares of Ketchum Common Stock having elected
                                   dissenters  rights,  as described  more fully
                                   herein;   all   governmental  and  regulatory
                                   consent and approvals  having been  obtained,
                                   and no court or governmental authority having
                                   taken any  action to  prohibit  or enjoin the
                                   Merger;   and  other   conditions  usual  and
                                   customary in similar  business  transactions.
                                   All conditions to the Merger other than those

                                   of the  parties to the  Merger.  In the event
                                   that  a  condition   of  the  Merger  is  not
                                   satisfied,  the Merger may be abandoned  even
                                   if prior thereto the Merger has been approved
                                   by the Ketchum Shareholders.  See "The Merger

                              Other Considerations

   
Recommendation of the
Ketchum Board of Directors .....   The Board of  Directors  of Ketchum  believes
                                   that  the  Merger  is fair to and in the best
                                   interests   of,   Ketchum   and  the  Ketchum
                                   Shareholders,  from  the  point  of  view  of
                                   Ketchum's long-term strategic objectives, the
                                   terms of the Merger Agreement,  and Ketchum's
                                   alternatives to the Merger,  all of which are
                                   more  fully   discussed   under  "The  Merger
                                   Agreement and the  Merger--Background  of the
                                   Ketchum's    Reasons    for    the    Merger;

                                   Directors."   Accordingly,   the   Board   of
                                   Directors of Ketchum has unanimously approved
                                   the  Merger  Agreement  and the  transactions
                                   contemplated   thereby  and   recommends  its
                                   approval by the Ketchum Shareholders.

Interests of Certain Persons
in the Merger ..................   As  of  the  Record   Date,   directors   and
                                   executive officers of Ketchum owned of record
                                   an aggregate of  approximately  56.70% of the
                                   outstanding  shares of Ketchum  Common Stock,
                                   and the Profit Sharing Plan owned 100% of the
                                   outstanding   shares  of  Ketchum   Preferred
                                   Stock.  Each of such  directors and executive
                                   officers,  and  the  Trustee  of  the  Profit
                                   Sharing  Plan,  has expressed an intention to
                                   vote his or her  shares of  Ketchum  Stock in
                                   favor of the various proposals.  Accordingly,
                                   these  proposals can be approved  without the
                                   affirmative   vote  of  any   other   Ketchum
                                   Shareholder. 

                                   For a  description  of certain  interests  of
                                   certain  directors and executive  officers of
                                   Ketchum in the Merger that are in addition to
                                   the   interests   of   Ketchum   Shareholders
                                   generally,  see "The Merger Agreement and the
                                   Merger--Interests  of Ketchum's Management in
                                   the Merger".
    
Certain Federal
Income Tax Consequences ........   The  Merger  is  intended  to be a  tax  free
                                   reorganization  within the meaning of Section
                                   368(a) of the United States Internal  Revenue
                                   Code of 1986,  as amended  (the  "Code").  In
                                   general,  the Ketchum  Shareholders  will not
                                   recognize  gain or loss  as a  result  of the
                                   exchange of Ketchum Stock for Omnicom  Common
                                   Stock as a  result  of the  Merger.  However,
                                   receipt of cash in lieu of fractional  shares
                                   or in connection  with appraisal  rights as a
                                   dissenting   shareholder  may  give  rise  to
                                   taxable income. See "The Merger Agreement and
                                   the   Merger--Other   Considerations--Federal
                                   Income     Tax     Consequences."     Ketchum
                                   Shareholders   should   consult   their   tax
                                   advisors  regarding the tax  consequences  of
                                   the  Merger  to  them  in  their   particular
                                   circumstances.

Accounting Treatment ...........   The Merger will be  accounted  for by Omnicom
                                   as  a   pooling-of-interests   for  financial
                                   reporting   purposes   in   accordance   with
                                   generally accepted accounting principles. See
                                   "The Merger  Agreement and the  Merger--Other
                                   Considerations--Accounting Treatment".

   
Regulatory Approvals ...........   Omnicom and Ketchum  each filed  notification
                                   and report forms under the Hart-Scott  Rodino
                                   Antitrust   Improvements   Act  of  1976,  as
                                   amended  (the  "Hart-Scott-Rodino  Act") with

                                   Department  (the  "Antitrust   Division")  on
                                   March 13, 1996, and each was advised that the

         The Escrow Agreement and the Ketchum Shareholder Representative

The Escrow Agreement ...........   As  described  above  under  "Description  of
                                   Certain Terms of the Merger-- Indemnification
                                   Obligations",   indemnification   obligations
                                   arising out of the Merger  Agreement  will be
                                   satisfied from shares of Omnicom Common Stock
                                   placed into the  General  and Special  Escrow
                                   Funds established under the Escrow Agreement.
                                   The  General  Escrow  Fund  will  consist  of
                                   shares  of  Omnicom  Common  Stock  having an
                                   aggregate  Market  Value of  $4,400,000;  the
                                   Special Escrow Fund will consist of shares of
                                   Omnicom  Common  Stock  having  an  aggregate
                                   Market Value of $2,500,000.

                                   Each of the Ketchum Common  Shareholders will
                                   be  depositing  his  pro  rata  share  of the
                                   General  Escrow  Fund or Special  Escrow Fund
                                   determined  by   multiplying   the  aggregate
                                   number of shares of Omnicom Common Stock by a
                                   fraction,  the  numerator  of  which  is  the
                                   number  of  shares of  Omnicom  Common  Stock
                                   issuable to such individual in the Merger and
                                   the  denominator of which is the total number
                                   of shares of Omnicom Common Stock issuable to
                                   all Ketchum Common  Shareholders,  rounded up
                                   to the nearest whole share.

   
                                   Based upon the  assumptions  set forth  above
                                   under  "Conversion of Ketchum Stock",  of the
                                   $125.24 Common Stock Conversion Price payable
                                   in respect  of each  share of Ketchum  Common
                                   Stock,   Omnicom   Common   Stock  having  an
                                   aggregate  Market  Value of  $12.26  would be
                                   deposited  in the General  Escrow  Fund,  and
                                   Omnicom  Common  Stock  having  an  aggregate
                                   Market  Value of $6.97 would be  deposited in
                                   the Special  Escrow  Fund.  Since the amounts
                                   held in such  Escrow  Funds  are  subject  to
                                   claims in respect of contingent  liabilities,
                                   there can be no  assurance  that amounts held
                                   therein  will in fact be  distributed  to the
                                   Ketchum Common Shareholders.
    

                                   For purposes of satisfying  any claims,  each
                                   share of Omnicom  Common  Stock  deposited in
                                   either  Escrow  Fund  will be  valued  at the
                                   Market    Value,    regardless    of   actual
                                   fluctuations  in  the  market  value  of  the
                                   Omnicom  Common  Stock  after the date of the
                                   Closing of the Merger Agreement.

                                   See "The  Escrow  Agreement  and the  Ketchum

          1. A proposal to approve  the Merger  Agreement  and the  transactions
     contemplated  thereby,  including without  limitation the Merger of OmniSub
     with and into  Ketchum  pursuant  to the  Merger  Agreement  such  that the

          3. Such other  proposals  as may  properly  come  before  the  Special
     Meeting or any adjournment thereof.

     None of the proposals  shall become  effective  unless all of the proposals
are adopted by the requisite vote of the Ketchum Shareholders.

                           Record Date; Voting Rights

   
     Only  shareholders of record of Ketchum Common Stock and Ketchum  Preferred
Stock as at the close of  business on April 15, 1996 will be entitled to vote at
the Special  Meeting.  On that  Record  Date there were  issued and  outstanding
358,818  shares of Ketchum  Common Stock and 6,282  shares of Ketchum  Preferred
Stock.  Each share of  Ketchum  Stock is  entitled  to one vote per share on the
Ketchum Vote Matters at the Special Meeting or any  adjournment  thereof whether
such  vote is cast as part of a vote of the  Ketchum  Common  Stock  or  Ketchum
Preferred Stock voting separately as a class, or as part of a collective vote of
all Ketchum Stock.
    

                               Voting Requirements

     The presence of the holders of a majority of the voting power of all shares
of Ketchum  Common Stock and of the holders of a majority of the voting power of
all shares of Ketchum  Preferred  Stock,  in each case  entitled  to vote on the
Record Date, is necessary to constitute a quorum for the transaction of business
at the Special Meeting.

     Under the Pennsylvania  Business  Corporation Law of 1988 (the "PABCL") and
the Ketchum Articles of Incorporation (the "Ketchum Articles"),  the approval of
the Merger Agreement and the transactions  contemplated thereby will require the
affirmative  votes of the  holders of a majority of the  Ketchum  Common  Stock,
voting as a class,  and of the holders of a majority  of the  Ketchum  Preferred
Stock,  voting  as a  class.  The  approval  of the  Escrow  Agreement  and  the
appointment of the Ketchum  Shareholder  Representative,  or the approval of any
other  proposals as may  properly be brought  before the Special  Meeting,  will
require the  affirmative  vote of the holders of a majority of the voting  power
represented  by the  outstanding  shares of  Ketchum  Common  Stock and  Ketchum
Preferred Stock, voting together as a single class.  Abstentions have the effect
of negative votes.

     Notwithstanding  the provisions of Pennsylvania  law, the Merger  Agreement
requires as a condition of the Closing of the Merger  Agreement  that all of the
shares of Ketchum Stock held by the Ketchum  Profit Sharing Plan shall have been
voted in favor of the Merger.

Prospectus/Information  Statement  forms a part is  qualified in its entirety by
reference to the  complete  text of the Merger  Agreement,  which is filed as an
Exhibit thereto and is incorporated herein by reference.)


    Background of and Ketchum's Reasons for the Merger; Recommendation of the
                           Ketchum Board of Directors

Overview

     After  the  Merger  is  effective,  Ketchum  will  continue  as a  separate
subsidiary of Omnicom and continue to conduct its business through three primary
operating divisions,  Ketchum Public Relations,  Ketchum Advertising and Ketchum
Directory  Advertising.  It is anticipated  that the senior  management of these
significant operating divisions of Ketchum will continue to serve as officers of
such operating divisions. Paul H. Alvarez, the Chairman, Chief Executive Officer
and  President of Ketchum,  will become  employed by Omnicom as Vice Chairman of
its Diversified Agency Services division and will remain an officer and director
of Ketchum.  See "The Merger  Agreement  and the Merger --  Interests of Ketchum
Management  in  the  Merger"  for  a  description  of  proposed  employment  and
non-competition  agreements between Ketchum and certain officers of Ketchum,  to
be entered into upon the Closing of the Merger Agreement.

     The  initial  Board of  Directors  of  Ketchum  immediately  following  the
Effective  Time of the  Merger  will be  composed  of three  directors:  Paul H.
Alvarez, Peter I. Jones (who is currently the President of Omnicom's Diversified
Agency Services  division),  and Barry J. Wagner (who is currently the Secretary
of Omnicom).

     The  terms of the  Merger  Agreement,  including  the  terms of the  Escrow
Agreement,  are the result of arm's-length  negotiations between representatives
of Omnicom and representatives of Ketchum.


Background of the Merger

     In  1992,  Ketchum's  Board  of  Directors  (sometimes  referred  to as the
"Ketchum  Board") began a process of strategic  planning for the corporation and
also had  each of its  divisions  engage  in  similar  planning.  The  divisions
included the largest two, Advertising and Public Relations, as well as Directory
Advertising and two smaller operations.

     From an  overall  corporate  standpoint,  Ketchum  recognized  three  major
challenges: (i) first, to make its advertising division competitive for mid-size
and larger  clients;  this  required a substantial  international  network and a
strong presence in selected cities;  (ii) second,  to ensure the availability of
capital to allow Ketchum to purchase the shares of retiring  shareholders and to
allow for normal capital  replacement  as well as for growth and expansion;  and
(iii) third, the Ketchum Board determined that the  communication  opportunities
afforded in what has been called  "interactive"  communications  represented  an
excellent opportunity for all of the divisions of Ketchum.

                                       16
<PAGE>

      As a result of this analysis,  Ketchum first formed an interactive unit to
serve as a resource to all of the  divisions  and to serve  clients  directly as
well. Next, the Executive  Committee of the Ketchum Board (sometimes referred to
as  the  "Ketchum  Executive   Committee")   reviewed  several  capital  raising
alternatives,  including an initial public offering,  obtaining an individual or
institutional  equity  partner  (not from the  advertising  or public  relations
industries)  and making use of an employee stock  ownership  plan  ("ESOP"),  to
provide continuing capital.

   
     For a time, the Ketchum  Executive  Committee pursued the ESOP alternative.
In the spring of 1995 Ketchum  received an  unsolicited  expression  of interest
from a major advertising agency to acquire Ketchum. Senior financial officers of
Ketchum  and such  agency met on March 10,  1995 to review  Ketchum's  financial
information, and then held a meeting on April 11, 1995 among the senior officers
of such agency and Ketchum.  The agency proposed to acquire only certain Ketchum
operating units,  and its proposal did not assume  Ketchum's  long-term debt and
employee  stock loans.  The proposal  was a taxable  transaction  at the Ketchum
level,  with  additional  taxes accruing upon any  distributions  to the Ketchum
Shareholders.  This proposal  would have caused  Ketchum to incur  restructuring
costs,  and would have exposed Ketchum to business risks regarding  clients that
might not find the smaller Ketchum attractive.  Ketchum informed the agency that
the  proposal  was  unacceptable;   however,  the  Ketchum  Executive  Committee
determined to consider other acquisition opportunities.
 
     Ketchum retained AdMedia Corporate Advisors,  Inc. ("AdMedia") in September
1995 to assist Ketchum in identifying  acceptable  purchasers of Ketchum and, to
the  extent  requested,  to advise  Ketchum in  structuring  and  negotiating  a
transaction.  Ketchum's  agreement with AdMedia contains usual  confidentiality,
indemnification  and other terms and conditions,  and provides for a retainer of
$10,000  per month from  September  through  November  1995,  with the  retainer
increasing to $15,000 per month in December 1995 and for each month  thereafter.
The agreement  also provides for a transaction  fee based on the purchase  price
received in any transaction,  plus reimbursement of out-of-pocket costs. The fee
in respect of the Merger will be  $1,200,000,  provided  that any retainer  fees
paid after March 1996 will be credited against this transaction fee.

     In September 1995 Ketchum was again  approached by the  advertising  agency
that made the spring 1995 proposal,  and  negotiations  commenced,  with Ketchum
being assisted by AdMedia.  Several meetings between the financial  officers and
senior  executive  officers  of the  companies  were held,  and an  exchange  of
information occurred.

     AdMedia  initiated  discussions  with  Omnicom in  September  1995,  and on
September  28,  1995 senior  executives  of Omnicom and Ketchum met to discuss a
possible   transaction.   Omnicom  reviewed  Ketchum's  financial  and  business
information. On October 23 and 24, 1995, Ketchum's Executive Committee and Board
met to  discuss  the other  agency's  proposal  and the  Omnicom  expression  of
interest.  The Ketchum Board  encouraged the Ketchum senior officers to continue
discussions  with the other agency and with Omnicom;  AdMedia reported that none
of the other  agencies it had contacted  had  expressed  interest in exploring a
transaction.

     In November 1995 and on December 4, 1995 the other agency submitted revised
proposals to Ketchum, in each case consisting of a non-taxable stock transaction
using unregistered  stock, with escrows to secure Ketchum's  financial statement
representations  and warranties.  These revised proposals continued to have as a
condition the  acquisition of less than all of Ketchum's  operating  units and a
contingent valuation formula, which the Ketchum Board had previously found to be
unacceptable.  In early December,  Omnicom also submitted a proposal to Ketchum.
Ketchum  reviewed both proposals with AdMedia.  On December 12, 1995 Ketchum met
with senior Omnicom officers,  and on December 13, 1995, Ketchum met with senior
officers of the other agency.

      After several  additional  meetings with Omnicom and its  representatives,
including detailed reviews of Ketchum's balance sheet and financial  statements,
an agreement in principle was reached between the parties.  Ketchum held a Board
meeting on January 4, 1996 at which the Ketchum Board  approved in principle the
Merger and related  transactions and determined to discontinue  discussions with
the other agency,  and a press release announcing the proposed Merger was issued
on January 10, 1996. A first draft of the Merger  Agreement was circulated among
the parties on January 24, 1996.  Several  meetings were held, both among senior
financial  officers  of  Ketchum  and of  Omnicom,  and among  their  respective
attorneys,  to propose,  discuss and ultimately agree upon changes to the draft.
On March 5, 1996,  the parties came to a final  agreement on the purchase  price
and other  significant  terms of the  Merger,  and on March 7,  1996 the  Merger
Agreement was executed and delivered by the parties.

Ketchum's Reasons for the Merger

     The Ketchum Board of Directors has determined that the Merger Agreement and
the Merger are  advisable  and in the best  interests of Ketchum and the Ketchum
Shareholders and has approved the Merger Agreement and Merger.

   
     In reaching  the  determination  that the Merger  Agreement  is in the best
interests of Ketchum and the Ketchum  Shareholders,  the Ketchum Board consulted
with Ketchum management and with AdMedia.  The Ketchum Board considered a number
of factors, including, without limitation, the following:

     (i)    Long-Term Strategic Objectives.  The Ketchum Board believed that the
            Merger would fulfill Ketchum's major long-term strategic  objectives
            by making its  advertising  division  competitive  for  mid-size and
            larger clients through Omnicom's substantial  international network,
            and by  ensuring  the  availability  of  capital  for a  variety  of
            purposes, including growth and expansion.

     (ii)   Complementary   Business  Operating  Units.  Ketchum   Advertising's
            affiliation  with a  substantially  larger agency,  such as Omnicom,
            would   afford  it  access  to   Omnicom's   international   service
            facilities,   clients,  and  financial  and  managerial   resources.
            Ketchum's  Public  Relations  Division  would be able to work within
            Omnicom,  with access to Omnicom's  financial resources and clients,
            as well as Omnicom's  extensive  international  service  facilities.
            Ketchum Directory  Advertising would benefit from the opportunity to
            service Omnicom clients.

     (iii)  Fairness of the Consideration. The establishment of a purchase price
            carrying a  substantial  premium  over the book value of the Ketchum
            Common  Stock as at December  31, 1995 and the  opportunity  for the
            holders of the Ketchum  Preferred  Stock to receive the  liquidation
            preference  on  their  shares,   together  with  the  provision  for
            Ketchum's obligations with respect to contingent liabilities related
            primarily to "change of control" premiums to former shareholders and
            pending litigation.

     (iv)   Unsatisfactory  Alternatives.  The proposal by Omnicom was deemed to
            be more  favorable  than the  offer of the  other  agency,  since it
            provided for more value to the Ketchum Shareholders without the risk
            of  a  contingent  valuation  formula,  was  for  all  of  Ketchum's
            operating units, resulted in a better business fit among the Ketchum
            and Omnicom  operating units, had a better business culture fit with
            Ketchum's  managers,  and  provided a structure  which  avoided both
            current taxation to Ketchum  Shareholders and the expense to Ketchum
            of restructuring its remaining  operations.  Ketchum management also
            noted that the  efforts of AdMedia and  Ketchum  management  had not
            identified any other acquisition candidates,  principally due to the
            insufficient  size of  potential  purchasers  or  identified  client
            conflicts that would make a combination unlikely or impracticable.

     (v)    Financial  Condition of Ketchum.  Information  relating to Ketchum's
            financial  condition,  results  of  operations,  capital  levels and
            management's best estimates of Ketchum's prospects.

     (vi)   Terms of the  Merger  Agreement.  The  terms and  conditions  of the
            Merger  Agreement,  including (a) the condition that the Merger will
            be a tax-free reorganization for federal tax purposes to the Ketchum
            Shareholders  and (b) the  conversion  of the Ketchum  Shareholders'
            shares of  Ketchum  Stock for  Omnicom  Common  Stock,  provide  the
            Ketchum  Shareholders  with liquidity in their  investment at a fair
            value,   without   resulting   in  a  taxable   event  for   Ketchum
            Shareholders.

     (vii)  Value and Liquidity of Omnicom Common Stock. Omnicom Common Stock is
            traded on the New York Stock Exchange;  Ketchum  Shareholders  would
            obtain a liquid  security in exchange for their illiquid  investment
            in Ketchum.
    

Recommendation of the Ketchum Board of Directors

   
     The  decision of the  Ketchum  Board to approve  and  recommend  the Merger
Agreement and the Merger was based on a number of factors, including the Ketchum
Board's knowledge of the business,  operations,  properties, assets and earnings
of Ketchum and its assessment of Ketchum's long-term prospects;  the opportunity
for  Ketchum  to  achieve   long-term   strategic  and  financial   benefits  by
consummating  the  Merger,  including  the  condition  that the Merger will be a
tax-free   reorganization  for  federal  income  tax  purposes  to  the  Ketchum
Shareholders;  the opportunity for the holders of the Ketchum Preferred Stock to
    

                                       18
<PAGE>

   
receive the  liquidation  preference on such shares;  the market prices at which
the shares of Omnicom  Common Stock have traded  during the past year;  the fact
that Omnicom Common Stock is traded on the New York Stock Exchange and, thus, is
a liquid investment whereas Ketchum Stock has no trading activity;  and the fact
that the Ketchum  Shareholders would receive a substantial premium over the book
value of the Ketchum Common Stock as of December 31, 1995. The Ketchum Board did
not attach a  relative  weight to the  factors it  considered  in  reaching  its
decision,  but,  considering all factors herein  discussed,  determined that the
Merger Agreement and the Merger are fair to and in the best interests of Ketchum
and the Ketchum Shareholders.
    

     For the reasons set forth above, the Ketchum Board believes that the Merger
is fair to, and in the best interests of,  Ketchum and the Ketchum  Shareholders
and recommends that the Ketchum Shareholders vote FOR the approval of the Merger
Agreement and the transactions contemplated thereby.

                        Omnicom's Reasons for the Merger

     Omnicom's  Board of  Directors  believes  that  the  Merger  represents  an
opportunity to strengthen the reach of its Diversified  Agency Services division
through the  acquisition  of a  full-service  marketing  communication  services
company with particular  strengths in public  relations,  consumer  advertising,
directory advertising and other related activities.

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

   
     In reaching its  conclusion,  the Omnicom  Board of  Directors  considered,
among other  things,  (i)  information  concerning  the  financial  performance,
condition,  business operations and prospects of Ketchum;  and (ii) the proposed
terms and  structure  of the  Merger.  Although  net income per share of Omnicom
Common Stock on a pro forma basis is lower than Omnicom's  historical net income
per common share, it is anticipated, based upon Ketchum's anticipated net income
for  1996,  that  the  Merger  will be  non-dilutive  to  Omnicom's  results  of
operations for 1996 and future years. Accordingly,  Omnicom's Board of Directors
has unanimously approved the Merger and the transactions contemplated thereby.

                 Interests of Ketchum's Management in the Merger

     (The following  describes  certain interests of the directors and executive
officers  of Ketchum in the Merger  that are in  addition  to the  interests  of
Ketchum Shareholders generally.)

     Pursuant to the Merger  Agreement,  Omnicom  will enter into an  employment
agreement  with Paul H.  Alvarez,  the  Chairman,  Chief  Executive  Officer and
President  of Ketchum and one of its  directors,  pursuant to which Mr.  Alvarez
would be  employed  as the Vice  Chairman  of the  Diversified  Agency  Services
division of Omnicom.  In addition,  pursuant to the Merger  Agreement,  KCI will
enter into employment  agreements with each of the following  executive officers
of  Ketchum:  David R.  Drobis,  John C.  Joseph,  Raymond  L.  Kotcher,  Dianne
Snedaker, Lorraine Thelian, Lawrence R. Werner and Edward L. Graf.

     It is  anticipated  that,  except as indicated  below,  the new  employment
agreements  will have a term  commencing at the Effective  Time and ending three
years thereafter (subject to an "evergreen"  provision  terminable on one year's
notice by Ketchum  and six  months'  notice by the  executive),  and provide for
annual salary  compensation and fringe benefits  substantially  the same as such
persons were receiving immediately prior to the Merger. The employment agreement
for Mr. Graf will have a term  commencing at the  Effective  Time and ending one
year thereafter (subject to the same "evergreen" provision terminable on 30 days
notice).  In the event Mr. Graf's employment is terminated by Ketchum other than
for cause,  Mr. Graf will be entitled  to receive one year's  severance  pay. In
addition,  on March 2, 1996 the existing employment agreement between KCI and J.
Craig Mathiesen,  a director and key executive of Ketchum, was extended from its
March 2, 1996 expiration date for a period up to two years.

     In  addition,  pursuant to the terms of the Merger  Agreement,  each of the
executives  who is entering  into an  employment  agreement as described  above,
including Mr. Mathiesen,  will also enter into a non-competition  agreement with
Omnicom and Ketchum.  Robert C. Feldman and James V. Ficco, who are directors of
Ketchum,  will also enter into a  non-competition  agreement  with  Omnicom  and
Ketchum.  There is no additional  consideration  being paid in  connection  with
these non-competition agreements.

   
     Finally,  the current  directors of Ketchum and the holders of more than 5%
of the Ketchum Common Stock have executed a Contribution  Agreement  pursuant to
which they have  agreed to  indemnify  the  Ketchum  Shareholder  Representative
against all losses and expenses  which may be incurred by him as a result of any
dispute arising from the  performance of his duties under the Escrow  Agreement,
unless such dispute is the result of his gross  negligence  or actions  taken in
bad   faith.   See  "The   Escrow   Agreement   and  the   Ketchum   Shareholder
Representative--Appointment of the Ketchum Shareholder Representative".
    

                  Procedure for Distributing Shares of Omnicom
                      Common Stock to Ketchum Shareholders

     A transmittal form will be furnished to Ketchum  Shareholders  prior to the
Effective  Time  of the  Merger  for  use  in  transmitting  their  certificates
evidencing  their  shares of  Ketchum  Stock to  Omnicom  to  exchange  them for
certificates evidencing the Omnicom Common Stock to which they are entitled as a
result  of the  Merger.  The  instructions  on the form of  transmittal  must be
complied with by each surrendering shareholder.

     On or as soon as  practicable  after the  Closing of the Merger  Agreement,
each Ketchum  Shareholder  shall receive by first-class  mail in accordance with
the  instructions  of  such  Ketchum  Shareholder  as  set  forth  in his or her
transmittal  form, a certificate  or  certificates  representing  the next lower
number of whole shares of Omnicom  Common Stock into which the shares of Ketchum
Stock  represented by the certificate or certificates of Ketchum Common Stock or
Ketchum Preferred Stock so surrendered shall have been converted pursuant to the
Merger and, in addition,  cash in lieu of a  fractional  share that such Ketchum
Shareholder  is entitled to receive,  subject in the case of the Ketchum  Common
Stock to the provisions of the Escrow Agreement  described  below.  Each Ketchum
Common  Shareholder will also receive a receipt  indicating the number of shares
of Omnicom Common Stock being held in the General Escrow Fund and Special Escrow
Fund in the name of such Ketchum Shareholder.

     Dividends  and other  distributions  which may be  payable  by  Omnicom  to
holders of record of Omnicom  Common  Stock as of a date on or after the date of
the Closing of the Merger  Agreement and which are paid prior to the delivery of
Omnicom Common Stock to Ketchum Shareholders  entitled thereto,  will be paid to
such former  Ketchum  Shareholders  at the same time the Omnicom Common Stock is
transferred to them upon surrender of certificates  representing their shares of
Ketchum  Stock.  Such  former  shareholders  will not be entitled to interest or
earnings on such dividends or other distributions pending receipt.

                              The Merger Agreement
The Merger

     Under the  terms of the  Merger  Agreement,  at the  Effective  Time of the
Merger,  OmniSub will be merged with and into Ketchum,  whose separate corporate
existence will continue as a wholly-owned subsidiary of Omnicom.

Conversion Prices

     Under  the terms of the  Merger  Agreement,  at the  Effective  Time,  each
outstanding  share of Ketchum  Stock will be  converted  into  shares of Omnicom
Common Stock based upon the  Conversion  Prices  described  below and the Market
Value of the Omnicom Common Stock. No fractional  shares of Omnicom Common Stock
will be issued but in lieu  thereof  each holder of shares of Ketchum  Stock who
would  otherwise  have been entitled to a fraction of a share of Omnicom  Common
Stock will be paid the cash  value of such  fraction  of a share  based upon the
Market Value thereof.

     The "Common Stock  Conversion  Price" will result in an amount per share of
Ketchum Common Stock equal to  $44,940,000  divided by the number of outstanding
shares of Ketchum Common Stock;  the  "Preferred  Stock  Conversion  Price" will
result  in an  amount  per  share  of  Ketchum  Preferred  Stock  equal  to  its
liquidation  preference of $1,000.  These dollar  amounts will then be converted
into a number of shares of Omnicom  Common  Stock  based upon the average of the
closing  prices  per share of the  Omnicom  Common  Stock on the New York  Stock
Exchange  during the 20  consecutive  trading  days ending three  business  days
immediately prior to the date of the Special Meeting. Accordingly,  although the
actual  conversion  exchange  rates cannot be  calculated as of the date of this
Prospectus/Information  Statement, they will be known by the date of the Special
Meeting and will be available to the attendees thereof.

   
     Based upon the assumption as set forth in the Summary under "Description of
Certain Terms of the Merger Agreement -- Conversion of Ketchum Stock" that there
would be 358,818  shares of Ketchum  Common Stock  outstanding  at the Effective
Time of the  Merger,  subject to the  obligation  to  deposit  shares of Omnicom
Common Stock into the Escrow Funds pursuant to the Escrow Agreement,  each share
of Ketchum  Common Stock would be converted  into the right to receive shares of
Omnicom Common Stock having an aggregate Market Value of $125.24; based upon the
Market Value of $41,  this would  equate to 3.05 shares of Omnicom  Common Stock
for each share of Ketchum Common Stock.  Each share of Ketchum  Preferred  Stock
would be  converted  into the right to receive  24.39  shares of Omnicom  Common
Stock.

     The Closing of the Merger  Agreement  has been  scheduled for May 31, 1996,
the day after the date of the  Special  Meeting.  However,  the  Closing  of the
Merger  Agreement  may be delayed  beyond May 31, 1996 if all  conditions of the
Merger  have not  been  satisfied  or  waived  by such  date;  there  will be no
adjustment to the  Conversion  Prices if this occurs,  notwithstanding  that the
actual value of the Omnicom Common Stock could fluctuate between the date of the
Special Meeting and the date of the Closing of the Merger Agreement. At the time
this   Prospectus/Information   Statement   is  being   mailed  to  the  Ketchum
Shareholders,  Omnicom  has no reason to believe  that the Closing of the Merger
Agreement will not be held on May 31, 1996 as scheduled.
    

Indemnification Obligations

     Under the Merger Agreement, the Ketchum Common Shareholders are required to
indemnify,  defend and hold harmless Omnicom and OmniSub,  and their affiliates,
directors,  officers and for (i) liabilities,  obligations,  losses,  penalties,
claims, actions, judgments or causes of action,  assessments,  costs or expenses
(including, without limitation, reasonable attorneys' fees and disbursements) as
a  consequence  of or in  connection  with  any  inaccuracy  or  breach  of  any
representation, warranty or covenant of Ketchum contained in or made pursuant to
the Merger Agreement, but only to the extent, with certain exceptions, that such
losses  exceed  $100,000  and (ii) any  expenses  being  incurred  by Ketchum in
connection  with the ongoing  reorganization  of the media buying  operations of
KCI.  Holders  of  Ketchum  Preferred  Stock are not  required  to  provide  any
indemnification under the Merger Agreement.

     To  satisfy  these   indemnification   obligations,   the  Ketchum   Common
Shareholders will deposit shares of Omnicom Common Stock into the General Escrow
Fund and the Special Escrow Fund under the Escrow Agreement.  The General Escrow
Fund will contain  shares of Omnicom  Common  Stock  having an aggregate  Market


                                       21
<PAGE>

   
Value of $4,400,000 and will be used to satisfy the indemnification  obligations
described under clause (i) of the preceding  paragraph;  the Special Escrow Fund
will contain shares of Omnicom Common Stock having an aggregate  Market Value of
$2,500,000 and will be used to satisfy the indemnification obligations described
under  clause  (ii)  of the  preceding  paragraph.  Indemnification  obligations
arising under clause (i) may be satisfied only from the General Escrow Fund, and
those  arising under clause (ii) may be satisfied  only from the Special  Escrow
Fund. Each Ketchum Common  Shareholder  will be depositing his pro rata share of
the General  Escrow Fund or Special Escrow Fund (rounded up to the nearest whole
share).  Accordingly,  of the shares of Omnicom Common Stock issuable in respect
of each share of Ketchum Common Stock,  shares of Omnicom Common Stock having an
aggregate  Market Value of $12.26 will be deposited into the General Escrow Fund
and shares of Omnicom  Common Stock  having an  aggregate  Market Value of $6.97
will be deposited into the Special Escrow Fund.
    

     The indemnification obligations of the Ketchum Common Shareholders, will be
limited to and satisfied solely from, the General Escrow Fund and Special Escrow
Fund  under the  Escrow  Agreement  (such that  neither  Omnicom  nor any of its
affiliates will have any recourse for the payment of any losses or other damages
arising out of the transactions contemplated by the Merger Agreement against any
Ketchum Shareholder,  nor shall any Ketchum Shareholder be personally liable for
any such losses or damages).  Indemnification obligations to be satisfied out of
the General Escrow Fund will  terminate on the earlier of the first  independent
audit report, if any, of the surviving  corporation following the Effective Time
of the Merger or one year from the Effective  Time (except that claims  asserted
in writing on or prior to such date will survive  until they are decided and are
final and binding on the parties).  Indemnification  obligations to be satisfied
out of the Special  Escrow Fund will  terminate on December 31, 1996,  being the
latest  date by which it will be  determined  whether  or not  costs  have  been
incurred in  connection  with the  ongoing  reorganization  of the media  buying
operations (except that claims asserted in writing on or prior to such date will
survive until they are decided and are final binding on the parties).


Representations and Warranties

     The  Merger  Agreement  contains  various  customary   representations  and

similar  corporate  matters of  Ketchum  and each of the  subsidiaries;  (b) the

     Pursuant to the Merger  Agreement,  Omnicom has agreed to cause  Ketchum to
maintain  in effect  for three  years (or a lesser  period of time,  in  certain
events) the current policies of directors' and officers' liability insurance and
fiduciary liability  insurance  maintained by Ketchum, or to substitute therefor
policies containing substantially the same coverage.

     Pursuant to the Merger Agreement,  Ketchum and Omnicom have covenanted with
one another to take certain additional  actions,  including without  limitation:
(a) to each take all corporate and other action, make all filings with courts or
governmental authorities and use its reasonable efforts to obtain in writing all
approvals and consents  required to be taken, made or obtained by it in order to
effectuate the Merger; (b) to prepare this Prospectus/Information  Statement and
the Registration  Statement of which it is a part, with each party  representing
and warranting to the other as to the accuracy of the information supplied by it
for inclusion herein;  and (c) to each use its reasonable  efforts to consummate
the Merger and the other transactions contemplated by the Merger Agreement.

Certain Conditions to the Merger

Agreement and the appointment of the Ketchum  Shareholder  Representative by the
Ketchum  Shareholders  at the Special  Meeting,  and to the required  regulatory
approvals,  the  respective  obligations  of  Omnicom,  OmniSub  and  Ketchum to

Agreement  prior to the  Closing;  (iii) the  absence  of any  material  adverse

Omnicom  Common  Stock on the New York Stock  Exchange;  (v) the  execution  and
delivery of the Escrow  Agreement;  (vi) the absence of any action or proceeding
enjoining the transactions  contemplated by the Merger Agreement;  and (vii) the
absence of any action or proceeding by any governmental agency that might result
in enjoining the consummation of said transactions.

     The  obligations of Omnicom and OmniSub to effect the Merger are subject to
satisfaction of certain additional conditions including, without limitation: (i)
the  SEC's  not  having  objected  to  Omnicom's  treatment  of the  Merger as a
pooling-of-interests for accounting purposes; (ii) the execution and delivery of
employment  agreements  with key  executives  of Ketchum and the  execution  and
delivery of non-competition agreements by each of such individuals;  (iii) there
not having been a material  and adverse  change in the  business  and affairs of
Ketchum;  and (iv) holders of fewer than 3% of the outstanding shares of Ketchum

agreements described above. See "The Merger Agreement and the  Merger--Interests
of Ketchum Management in the Merger."

   
     Pursuant to the terms of the Merger Agreement,  each of Omnicom and Ketchum
is entitled to waive any of its conditions to  consummation of the Merger to the
extent that any such  condition  is not  satisfied  in full by the other  party,
other than  conditions  relating to the  treatment of the Merger by the SEC as a
pooling-of-interests  for accounting purposes,  the approval of the Ketchum Vote
Matters by the Ketchum  Shareholders and the absence of any action or proceeding
enjoining the transactions contemplated by the Merger Agreement.

Closing Date

   
      The  Closing  has  been  scheduled  for May 31,  1996,  assuming  that all
conditions to closing the Merger Agreement have been satisfied or waived by such
date. At the time this  Prospectus/Information  Statement is being mailed to the
Ketchum Shareholders, Omnicom has no reason to believe that the Closing will not
take place on May 31, 1996 as scheduled.

Omnicom,  OmniSub and Ketchum;  (b) by either  Omnicom and  OmniSub,  on the one
hand,  or  Ketchum,  on the  other  hand,  if there  has  been a  breach  of any

the Merger  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 Merger;  (c) by the Board of  Directors  of
Omnicom,  OmniSub  or  Ketchum  if a final and  nonappealable  order,  decree or

incapable of being satisfied by December 31, 1996.

Amendment

     The Merger 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.

                              Other Considerations

Federal Income Tax Consequences

   
     (The following is a summary of all federal income tax  consequences  of the
Merger that are material to the Ketchum  Shareholders.  It is based upon certain
representations and assumptions as set forth in the opinion of Deloitte & Touche
LLP  filed  as  an  Exhibit  to  this  Registration   Statement  of  which  this
Prospectus/Information  Statement is a part. No opinion has been expressed as to
the state,  local or foreign tax  consequences.  In addition,  the  following is
general  in  nature  and  does  not  take  into  account  the   particular   tax
circumstances of any individual Ketchum Shareholder. It is recommended that each
Ketchum Shareholder consult his own tax advisors as to the specific consequences
of the proposed Merger for such individual, including the application and effect
of state, local and foreign laws.)
    

     The Merger has been  structured  to qualify as a "tax-free"  reorganization
within the meaning of the Code.  Deloitte & Touche LLP, Ketchum's tax advisor in
the Merger,  has rendered its opinion as to the federal income tax  consequences
of the  Merger.  The  opinion  of  Deloitte & Touche LLP is based upon the Code,
regulations  now  in  effect  thereunder,  current  administrative  rulings  and
practice,  and judicial authority,  all of which are subject to change. Unlike a
ruling from the Internal Revenue  Service,  the opinion of Deloitte & Touche LLP
is not binding upon the Internal  Revenue Service and there can be no assurance,
and none is hereby  given,  that the  Internal  Revenue  Service will not take a
position contrary to one or more of the positions  reflected therein or that the
opinion  will be upheld by the  courts if  challenged  by the  Internal  Revenue
Service.

     In the  opinion  of  Deloitte  & Touche  LLP,  which  opinion is based upon
various  representations  and subject to various assumptions and qualifications,
the following  federal income tax consequences,  among others,  will result from
the Merger.

          1. The Merger will constitute a  reorganization  within the meaning of
     Section 368(a) of the Code.

          2. No gain or loss will be recognized by Ketchum Shareholders upon the
     exchange of their Ketchum Stock (including  fractional share interests they
     might otherwise be entitled to receive) solely for Omnicom Common Stock.

                                       24
<PAGE>

           3. The holding  period of the Omnicom  Common  Stock will include the
      holding  period for the Ketchum Stock  surrendered  in exchange  therefor,
      provided  the  Ketchum  Stock was held as a  capital  asset on the date of
      exchange.

          4. The  aggregate  basis of the  Omnicom  Common  Stock  received by a
     Ketchum   Shareholder   (including  any  fractional   share  interest  such
     Shareholder  might  otherwise  receive)  will be the same as the  aggregate
     basis of the Ketchum Stock surrendered in exchange therefor.

          5. The payment of cash in lieu of fractional shares will be treated as
     if the fractional  shares were distributed as part of the exchange and then
     redeemed by Omnicom. Any Ketchum Shareholder who receives cash in lieu of a
     fractional  share  interest in Omnicom  Common Stock will recognize gain or
     loss  measured by the  difference  between cash received in respect of such
     fractional  share and the portion of the basis of Ketchum  Stock  allocable
     thereto.  Similarly, a Ketchum Shareholder who dissents from the Merger and
     receives the "fair value" of his shares of Ketchum Stock in accordance with
     the PABCL (see  "Rights of  Dissenting  Ketchum  Shareholders"  below) will
     recognize gain or loss measured by the difference between the cash received
     and the basis of the Ketchum Stock.

     No ruling from the  Internal  Revenue  Service will be sought on any of the
foregoing federal tax consequences of the Merger.

     A copy of the opinion of Deloitte & Touche LLP has been filed as an Exhibit
to the Registration Statement of which this Prospectus/Information  Statement is
a part and is incorporated herein by reference.

Accounting Treatment

     Ketchum  and  Omnicom   expect  the  Merger  to  be  accounted   for  as  a
pooling-of-interests   for  financial  reporting  purposes  in  accordance  with
generally accepted accounting  principles.  Under pooling of interest accounting
upon consummation of the Merger,  the assets and liabilities of Ketchum would be
included in the  consolidated  balance sheet of Omnicom and its  subsidiaries in
the amounts which were included in the books of Ketchum  immediately  before the
Merger after  conforming  certain  accounting  policies and  procedures to those
currently used by Omnicom.

 Regulatory Approvals

   
     Under the  Hart-Scott-Rodino Act and the rules promulgated therewith by the
FTC, the Merger 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 Ketchum
each filed  notification and report forms under the  Hart-Scott-Rodino  Act with
the FTC and the  Antitrust  Division on March 13,  1996.  The  required  waiting
period under the Hart-Scott-Rodino Act expired on April 13, 1996.
    

     At any time  before or after  consummation  of the  Merger,  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 Merger or seeking  divestiture of assets of Omnicom.  At any
time before or after the Closing, 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 Merger 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 Ketchum  believe that
the Merger 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
Merger on antitrust  grounds will not be made or that, if such a challenge  were
made,  Omnicom  and  Ketchum  would  prevail or would not be  required to accept
certain  conditions,  possibly  including  certain  divestitures  of  assets  of
Omnicom, in order to consummate the Merger.

Resales of Omnicom Common Stock

      All shares of Omnicom Common Stock received by Ketchum  Shareholders  as a
result of the Merger 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 Ketchum prior to the Merger ("Ketchum

                                       25
<PAGE>

Affiliates") shall be subject to certain  restrictions,  as more fully described
below.  Persons  who may be  deemed  to be  affiliates  of  Ketchum  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
Merger  Agreement  provides  that  Ketchum  will  furnish  Omnicom  with  a list
identifying  all persons who may be  considered  to be Ketchum  Affiliates,  and
gives  Omnicom  the right to review such list and  require  changes.  Ketchum is
required  to use its best  efforts to cause each of the  Ketchum  Affiliates  to
execute a written  agreement  to comply  fully with the  restrictions  described
below, and the receipt of such written agreements from each Ketchum Affiliate is
a condition to Omnicom's obligation to consummate the Merger.

     Federal Securities Laws. Shares of Omnicom Common Stock received by Ketchum
Affiliates  may be  resold  by such  Ketchum  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
Merger, Ketchum 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 Ketchum after the Closing.  This prohibition precludes
the use of "hedging" techniques during this period.

Stock Exchange Listing

     It is a  condition  to the Merger that the shares of Omnicom  Common  Stock
required to be issued in connection with the Merger 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.]

Rights of Dissenting Ketchum Shareholders

     If the Merger is consummated,  under Section 1930 of the PABCL,  holders of
shares of Ketchum Stock with respect to which appraisal rights are perfected and
not withdrawn or lost, will be entitled to have the "fair value" of their shares
of  Ketchum  Stock at the  Effective  Time  (exclusive  of any  element of value
arising  from  the  accomplishment  or  expectation  of the  Merger)  judicially
determined  and  paid  to  them in cash by  complying  with  the  provisions  of
Subchapter D of Chapter 15 of the PABCL ("Subchapter D").

     The  following  is a brief  summary  of  Subchapter  D which sets forth the
procedures  for  dissenting  from the Merger and demanding  statutory  appraisal
rights.  This summary is qualified in its entirety by reference to Subchapter D,
a copy of the text of which is attached hereto as Annex I.

     Ketchum  Shareholders  of record who  desire to  exercise  their  appraisal
rights must satisfy all of the conditions set forth in Section 1930 of the PABCL
and in Subchapter D, which  conditions  include the  following  requirements.  A
written  notice of intention to demand "fair value" for shares of Ketchum  Stock
must be delivered to the  Secretary of Ketchum  before the taking of the vote on
the Merger  Agreement.  This written  demand must be in addition to and separate
from any proxy or vote abstaining from or against the Merger Agreement.  Neither
voting  against,  abstaining  from  voting,  nor  failing  to vote on the Merger
Agreement will  constitute a notice of intention to demand fair value within the
meaning of Subchapter D. Any Ketchum  Shareholder  seeking appraisal rights must
hold the shares of Ketchum  Stock for which  appraisal  is sought on the date of
the making of the demand,  continuously  hold such shares  through the Effective
Time, and otherwise comply with the provisions of Subchapter D.

   
     Ketchum  Shareholders  electing to exercise  their  appraisal  rights under
Subchapter D need not vote against the Merger in order to perfect such appraisal
rights;  abstentions are acceptable.  However,  dissenting Ketchum  Shareholders
must not vote for  approval  and  adoption of the Merger  Agreement  nor consent
thereto in writing.  Voting in favor of the Merger  Agreement,  or  delivering a
proxy in connection with the Special Meeting (unless the proxy votes against, or
expressly  abstains from the vote on, the Merger  Agreement),  will constitute a
waiver  of a Ketchum  Shareholder's  right of  appraisal  and will  nullify  any
written demand for appraisal submitted by the shareholder.
    

                                       26
<PAGE>

     The notice of  intention  to demand fair value  should  specify the Ketchum
Shareholder's  name and mailing  address,  the number of shares of Ketchum Stock
owned, and that the Ketchum Shareholder is thereby demanding appraisal of his or
her shares of Ketchum Stock. If the Merger is approved by Ketchum  Shareholders,
Ketchum  shall give  notice to all  Ketchum  Shareholders  who have  delivered a
notice of  intention  to demand  payment  of the fair  value of their  shares of
Ketchum Stock and have  otherwise  complied with  Subchapter D. The notice to be
delivered  by  Ketchum  shall,  among  other  things,  state  where and when the
dissenting Ketchum Shareholder should deliver (a) a demand for payment,  and (b)
the  certificates  representing the dissenting  shareholder's  shares of Ketchum
Stock.

     After the  dissenting  Ketchum  Shareholder  has  received  the notice from
Ketchum described in the preceding  paragraph,  the dissenting  shareholder must
both make written demand for payment and deliver the  certificates  representing
the Ketchum  Shareholders' Ketchum Stock in accordance with the instructions set
forth in the notice.

     Promptly  after  consummation  of the Merger and after timely  receipt of a
proper  demand  of  payment  and  of the  share  certificates  representing  the
dissenting  shareholder's  shares  of  Ketchum  Stock,  Ketchum  shall  remit to
dissenters  the amount that it estimates to be the fair value of the shares,  or
shall give written notice that no remittance  shall be made;  such remittance or
notice shall be accompanied, among other things, by the balance sheet and income
statement of Ketchum and its  subsidiaries  as at December  31, 1995,  [together
with an interim balance sheet and income statement as at _______,  1996.] If the
dissenter  believes  that the amount  stated or  remitted  is less than the fair
value of his shares of Ketchum Stock, he may send to Ketchum his own estimate of
the fair value,  which shall be deemed a demand for payment of the amount or the
deficiency.  If such a demand is not made within 30 days after the remittance or
notice by Ketchum,  the  dissenter  shall be entitled to no more than the amount
stated in the notice or remitted to him by Ketchum.

     Within 60 days after the later of the  Effective  Time,  the receipt of all
demands  for  payment,   or  timely  receipt  of  any  estimates  by  dissenting
shareholders  of the fair value of their  shares,  Ketchum  may file in court an
application for relief requesting a determination by the court of the fair value
of the  shares;  if  Ketchum  does  not  file  an  application,  the  dissenting
shareholder  may file an  application  in  Ketchum's  name,  subject to the time
restrictions set forth in Subchapter D.

     The cost of the  appraisal  proceeding  may be  determined by the court and
assessed   against  the  parties  as  the  court  deems   equitable   under  the
circumstances;  costs would be assessed against dissenting shareholders whom the
court finds to be dilatory, obdurate, arbitrary, vexatious or in bad faith.

     Any Ketchum  Shareholder who has duly demanded appraisal in compliance with
Subchapter  D will not be entitled to vote for any purpose the shares of Ketchum
Stock  subject  to such  demand or to  receive  payment  of  dividends  or other
distributions  on such  shares,  except  for  dividends  or other  distributions
payable to shareholders of record at a date prior to the Effective Time.

     In view  of the  complexity  of  these  provisions  of the  PABCL,  Ketchum
Shareholders  who are  considering  dissenting from the approval and adoption of
the Merger  Agreement  and  exercising  their rights  under  Subchapter D should
consult their legal advisors.

                          THE ESCROW AGREEMENT AND THE
                       KETCHUM SHAREHOLDER REPRESENTATIVE

The Escrow Agreement

     (The  information  contained in this  Registration  Statement of which this
Prospectus/Information Statement performs a part is qualified in its entirety by
reference  to the  complete  text of the Escrow  Agreement  which is filed as an
Exhibit thereto and is incorporated herein by reference.)

     As described above under "The Merger  Agreement and the Merger--the  Merger
Agreement--Indemnification  Obligations",  in order to  satisfy  indemnification
obligations  under the Merger Agreement,  the Ketchum  Shareholders will deposit
shares of Omnicom  Common  Stock into the  General  Escrow  Fund and the Special
Escrow Fund under the Escrow  Agreement.  The General  Escrow Fund will  contain
shares of Omnicom  Common Stock having an aggregate  Market Value of  $4,400,000
and the Special  Escrow Fund will contain  shares of Omnicom Common Stock having
an aggregate Market Value of $2,500,000.

     Each of the Ketchum Common  Shareholders shall be depositing his or her pro
rata share of the General  Escrow Fund or Special Escrow Fund (rounded up to the
nearest whole share) determined by multiplying the aggregate number of shares of
Omnicom  Common  Stock  required  to be  deposited  into such  Escrow  Fund by a
fraction, the numerator of which is the number of shares of Omnicom Common Stock
issuable to such  individual in the Merger and the  denominator  of which is the
total number of shares of Omnicom Common Stock issuable to all such  individuals
required to provide indemnification.

   
     Based upon the assumed number of  outstanding  shares set forth above under
"Conversion of the Ketchum Common Stock", of the $125.24 Common Stock Conversion
Price payable in respect of each share of Ketchum  Common Stock,  Omnicom Common
Stock  having an  aggregate  Market  Value of $12.26  would be  deposited in the
General Escrow Fund,  and Omnicom Common Stock having an aggregate  Market Value
of $6.97 would be deposited in the Special  Escrow Fund.  Based upon the assumed
Market Value of $41,  this would  result in 0.30 shares of Omnicom  Common Stock
per share of Ketchum  Common Stock being  deposited in the General  Escrow Fund,
and 0.17 shares of Omnicom  Common Stock per share of Ketchum Common Stock being
deposited in the Special Escrow Fund. Since the amounts held in the Escrow Funds
are subject to claims in respect of liabilities,  there can be no assurance that
amounts  held  therein  will  in  fact  be  distributed  to the  Ketchum  Common
Shareholders. If none of the amounts held therein are in fact distributed to the
Ketchum Common Shareholders,  then the actual Common Stock Conversion Price will
have been only $106.01,  equivalent to 2.59 shares of Omnicom Common Stock based
on the stated assumptions.
    

     For purposes of satisfying  any claims,  each share of Omnicom Common Stock
deposited in either Escrow Fund will be valued at the Market  Value,  regardless
of actual fluctuations of the market value of the Omnicom Common Stock after the
Closing of the Merger Agreement.

     Pursuant to the Escrow Agreement,  the Ketchum Shareholder  Representative,
on behalf of the Ketchum Common Shareholders,  shall grant to Omnicom a security
interest in the Escrow Funds to secure the  performance  of the  indemnification
obligations of the Ketchum Common  Shareholders  under the Merger  Agreement and
the performance of their obligations to Omnicom under the Escrow Agreement.

      The Escrow  Agreement  shall  automatically  terminate if and when all the
shares of  Omnicom  Common  Stock  held in either  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, upon determination
that an indemnification  payment is due to Omnicom from the General Escrow Fund,
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.  The  Ketchum
Shareholder  Representative  shall have the right to  dispute  any such claim by
Omnicom and require arbitration of the items in dispute.

     On the next business day following the earlier of (x) the first independent
audit report,  if any, of Ketchum following the Closing or (y) one year from the
Closing,  the Escrow Agent shall deliver to the Ketchum Common  Shareholders the
remaining  shares of Omnicom  Common Stock then on deposit in the General Escrow
Fund, as reduced by any amounts necessary to cover outstanding claims, including
claims then in dispute.

                                       28
<PAGE>

   
      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 the  Ketchum  Common  Shareholders,  shall be paid  directly to the
Ketchum Common Shareholders, and shall not constitute part of the General Escrow
Fund. Each Ketchum Common  Shareholder  shall be entitled to exercise all voting
rights with  respect to the shares of Omnicom  Common  Stock  deposited  by such
Ketchum Shareholder in the General Escrow Fund.
    

     Special Escrow Fund. The Escrow Agreement provided that, upon determination
that an indemnification  payment is due to Omnicom from the Special Escrow Fund,
the Escrow Agent shall deliver to Omnicom the number of shares of Omnicom Common
Stock,  valued  at the  original  Market  Value,  equal  to the  indemnification
payment. The Ketchum Shareholder  Representative shall have the right to dispute
any such claim by Omnicom and require arbitration of the items in dispute.

   
     The parties  have agreed that  December 31, 1996 will be the latest date by
which it will be  determined  whether any costs,  related to  severance,  excess
leased office space and asset write-offs,  have been incurred in connection with
the ongoing reorganization of the Ketchum media buying operations.  Accordingly,
on the next  business day  following  December 31, 1996,  the Escrow Agent shall
deliver to the Ketchum Common  Shareholders the remaining shares then on deposit
in the  Special  Escrow  Fund as  reduced  by any  amounts  necessary  to  cover
outstanding claims, including claims then in dispute.

     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 the  Ketchum  Common  Shareholders,  shall be paid  directly to the
Ketchum Common  Shareholders and shall not constitute part of the Special Escrow
Fund. Each Ketchum Common  Shareholder  shall be entitled to exercise all voting
rights with  respect to the shares of Omnicom  Common  Stock  deposited  by such
Ketchum Shareholder in the Special Escrow Fund.
    

Appointment of the Ketchum Shareholder Representative

     It is a condition to Closing  under the Merger  Agreement  that the Ketchum
Shareholders  appoint the  Ketchum  Shareholder  Representative  to act as their
collective agent in connection with the Escrow Agreement,  including one or more
alternative individuals to act as the Ketchum Shareholder  Representative in the
event that the designated Representative shall have died, resigned, or otherwise
become incapable or unwilling to act as Representative.

   
     Appointment  of the Ketchum  Shareholder  Representative  shall include the
specific  authorization  for such  Representative to (i) execute and deliver the
Escrow Agreement at the Effective Time of the Merger and any documents  incident
or   ancillary   thereto,   including   without   limitation   any   amendments,
cancellations,  extensions  or waivers in respect  thereof;  (ii) respond to and
make  determinations  in  respect  of the  assertion  of any and all  claims for
indemnification by Omnicom, and to assert claims on behalf of the Ketchum Common
Shareholders, pursuant to the terms of the Escrow Agreement and the terms of the
Merger Agreement pertaining thereto;  (iii) execute and deliver any stock powers
which may be required to be executed by any Ketchum Common Shareholder, in order
to permit the  delivery to Omnicom of any shares of Omnicom  Common  Stock to be
delivered to it pursuant to the Escrow  Agreement;  and (iv) take all such other
actions as may be necessary or  desirable to carry out his  responsibilities  as
collective agent of the Ketchum Shareholders in respect of the Escrow Agreement.
The terms of the appointment of the Ketchum Shareholder  Representative shall be
that he shall not be liable for any  mistake of fact or error of judgment or for
any  acts  or  omissions  unless  caused  by his  gross  negligence  or  willful
misconduct;  this term will be  confirmed  by each  Ketchum  Shareholder  in the
transmittal  form  furnished  by him to Omnicom as  described  under "The Merger
Agreement and the  Merger--Procedure  for Distributing  Shares of Omnicom Common
Stock to Ketchum  Shareholders".  In addition,  the current directors of Ketchum
and the  holders  of more than 5% of the  shares of  Ketchum  Common  Stock have
executed  a  Contribution  Agreement  pursuant  to which  they  have  agreed  to
indemnify the Ketchum Shareholder Representative against all losses and expenses
which  may be  incurred  by him as a  result  of any  dispute  arising  from the
performance of his duties under the Escrow Agreement, unless such dispute is the
result of his gross negligence or action taken in bad faith.
    

                                       29
<PAGE>

     Finally,  the appointment of the Ketchum Shareholder  Representative  shall
also  include the consent of the Ketchum  Shareholders  to the  procedure  to be
followed in the event the Ketchum Shareholder Representative and any alternative
shall be unable or unwilling to serve or continue to serve as such.  Pursuant to
such a procedure,  a new Ketchum Shareholder  Representative  shall be chosen by
majority  vote of those  persons who were members of Ketchum  Board of Directors
immediately  prior to the  Effective  Time of the  Merger,  any of whom shall be
entitled to call a meeting for such a purpose.

     The  proposal  before the Ketchum  Shareholders  is that Paul H. Alvarez be
appointed as Ketchum Shareholder  Representative,  with Edward L. Graf appointed
as alternate.  Messrs.  Alvarez and Graf are directors and executive officers of
Ketchum and Ketchum  Shareholders.  See "The Merger  Agreement and the Merger --
Interests  of  Ketchum's  Management  in the Merger" and  "Business  Information
Concerning Ketchum -- Executive Officers and Directors,  Principal Shareholders"
for more detailed descriptions of these interests.

Recommendation of the Ketchum Board of Directors

     The Ketchum  Board of  Directors  believes  that the adoption of the Escrow
Agreement is in the best  interests of the Ketchum  Shareholders  and recommends
that the Ketchum  Shareholders vote FOR the approval of the Escrow Agreement and
the  transactions  contemplated  thereby,  and  FOR the  appointment  of Paul H.
Alvarez as Ketchum Shareholder Representative, with Edward L. Graf as alternate.

Clients

   
     Ketchum's ten largest clients in 1995 accounted for approximately 41.12% of
income from  commissions and fees.  American Honda Motor Company was the largest
client  comprising 18% of commissions and fees. The second through tenth largest
clients  individually  comprised from 6% to 1% of commissions  and fees. For the
purposes of the foregoing percentages, a foreign subsidiary of a domestic client
(or vice versa) is deemed to be a separate  client where such  subsidiary  has a
right  to  select,  and  has  selected,   Ketchum's  subsidiary  abroad  as  its
advertising  agency as a matter of  independent  choice.  The major  clients  of
Ketchum's  subsidiaries  appear  in  various  promotional   materials.   Foreign
subsidiaries and affiliates  accounted for approximately  6.71% of the worldwide
total of income from commissions and fees of Ketchum in 1995.

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

                              Results of Operations

Performance in 1995 compared to 1994

   
      Revenues  from  commissions  and fees for 1995  increased  to $127.4  from
$124.1 million in 1994. The increase was primarily attributable to a significant
increase in commissions  and fees from the Public  Relations  Division which was
partially  offset by a decrease in the commissions and fees from the Advertising
Division,  due  primarily to the impact of closing  certain  offices in 1994 and
1995.

     Operating loss was $6.9 million in 1995 compared with  operating  income of
$6.6  million  in 1994.  The $13.5  million  change  consists  of $16.8  million
increase  in total  operating  expense  partially  offset  by the  $3.3  million
increase in  commissions  and fees.  With  respect to the  increase in operating
expenses,  $7.5 million  results from  increases  in  compensation  and employee
benefits and general agency  expense which are discussed  below.  Further,  $9.3
million  results  from the  increase in other  expense and  includes a charge of
approximately  $5.0 million related to settled and pending  litigation  matters,
the most  significant  of which was an  approximate  $4.0  million  charge for a
judgment  against Ketchum related to a prior  acquisition in the United Kingdom.
This case was a  contract  dispute  between  the  majority  owners  and  Ketchum
relative to the  exercise  of a put option  requiring  Ketchum to  purchase  the
majority stake as well as a dispute relating to certain  dividends  declared and
paid prior to the put without Ketchum's  consent.  Judgment was rendered against
Ketchum on  February  21, 1996 for  approximately  $3.5  million.  Additionally,
Ketchum was subsequently  ordered to pay $0.5 million for a cost contribution to
the plaintiffs' legal costs. The remaining $1.0 million of the litigation charge
primarily  relates  to two cases  where  judgments  have been  rendered  against
Ketchum  and loss is  considered  probable,  although  appeals are  pending.  An
additional  reserve of $0.5  million was  recorded in 1995,  in addition to $0.2
million  previously  accrued,  for the first case, a case in which Ketchum was a
minority  shareholder of a Parisian  advertising  agency which went bankrupt and
where  Ketchum may be required to contribute to the full amount of the shortfall
in net assets.  The potential range of loss in this case is between $0.7 million
and $1.2  million.  A charge of $0.3  million was  recorded  for the second case
which is related to Ketchum  holding  over in certain New York office  space for
one month. In management's opinion,  Ketchum's exposure for unrecorded losses of
all litigation matters is insignificant.

     Other  operating  expenses in 1995 also  included  charges  resulting  from
management's  periodic  analysis of the  recoverability of the carrying value of
the excess of cost over the fair value of net assets acquired.  Management wrote
down  approximately  $2.8  million of the  carrying  value at December 31, 1995.
Management's  analysis was based on  undiscounted  cash flows of expected future
performance  of the related  operations.  Expected  future cash flows were based
upon internal  projections  considering past trends,  general business  economic
conditions and discussions with key management personnel. To the extent that the
cash flows did not  support  the  carrying  value of the excess of cost over the
fair value of net assets acquired,  write downs were recorded.  The $2.8 million
write down relates  principally to two domestic  operations  which have incurred
significant  losses since 1992.  $1.1 million of the charge relates to Ketchum's
Public Relations  Division and $1.4 million relates to its Health Care Division.
Prior to 1995, management believed that these operations could be turned around.
However,  poor 1995 results of operations and projected losses led management to
conclude that write downs should be made in 1995. Additionally,  other operating
expenses in 1995  included  $1.1  million for the write off of notes  receivable
from equity investees, primarily from an investee which has incurred significant
losses since its formation  and which  continues to have  significant  cash flow
shortfalls.  Finally,  other operating expenses included $0.7 million for equity
in the net loss of  equity  investees.  This  represented  an  increase  of $0.4
million from 1994,  primarily  related to increased losses of the same investees
discussed above.

      Partially  offsetting the factors negatively  impacting operations in 1995
was decreased interest expense and an increase in other income. Interest expense
in 1994 included a $0.4 million charge  related to the  refinancing of Ketchum's
primary debt  instrument,  a 9% unsecured  senior note due August 1, 2004,  with
principal payable in equal annual installments  beginning August 1, 1998 through
August 1, 2004 and interest payable semi-annually.  The increase in other income
    

                                       37
<PAGE>

   
in  1995 is  primarily  due to a $0.4  million  dollar  gain on the  sale of the
Chicago office.

     Ketchum's net loss in 1995 was $7.5 million  compared to net income of $2.1
million in 1994.  The income tax benefit in 1995 of  approximately  $0.2 million
was less than that calculated using the U.S. federal  statutory rate.  Ketchum's
effective income tax rate was negatively impacted  principally by the effects of
certain nondeductible expenses and an increased valuation allowance for deferred
tax assets.
    

     The  discussion of results of operations of the operating  divisions  which
follows excludes the impact of other operating expenses discussed above.

   
     Commissions  and fees for the  Advertising  Division  were $58.1 million in
1995  compared  to  $61.4   million  in  1994  and  operating   income  for  the
corresponding  periods was $1.0  million  and $5.4  million,  respectively.  The
decrease in commissions  and fees was comprised of $3.5 million from the loss of
two  clients,  as well as lost  commissions  and fees of $2.2  million  and $2.4
million,  respectively,  as a result of the  closing  of offices in New York and
Philadelphia  in 1994,  and  offices  in  Chicago  and  Singapore  in 1995.  The
decreases  were  partially  offset by the growth of existing  businesses of $4.8
million. Operating income in 1995 was negatively impacted by the loss of the two
clients,   which  resulted  in  employee  severance  costs,  increased  business
development  costs  and a self  promotion  project.  The  loss of one of the two
clients in the fourth quarter of 1995 is expected to reduce commissions and fees
in 1996 by $4.4  million;  however it is  expected  that  operating  income will
decrease  by only $0.3  million as related  costs  have also been  reduced.  The
increases  in business  development  costs and the self  promotion  project were
aimed at generating new business and creating  general market  awareness for the
Advertising  Division  in  the  very  competitive  advertising  industry.  Costs
associated  with closing the  Singapore  office also further  reduced  operating
income.  Operating income in 1995 was favorably  impacted by savings  associated
with the closings of the New York,  Philadelphia  and Chicago  offices which had
previously incurred operating losses.

      Commissions and fees for the Public Relations  Division increased to $52.8
million  in 1995 from  $45.0  million  in 1994  while  operating  income for the
corresponding periods increased to $3.1 million from $2.9 million, respectively.
The  increase  in  commissions  and  fees  was  due to the  growth  of  existing
businesses,  including  net new  business  gains and  higher net  spending  from
existing clients. The operating profit percentage decreased to 5.9% in 1995 from
6.4% in 1994.  Operating income was negatively impacted by increased legal costs
associated  with a lawsuit  related  to a  previous  acquisition  in the  United
Kingdom, the results of which is discussed above in other operating expense.

     Commissions   and  fees  of  the  other  divisions   (primarily   Directory
Advertising  and  Health  Care) were $16.5  million  in 1995  compared  to $17.7
million in 1994 and  operating  losses were $1.4  million in both 1995 and 1994.
The  decrease  in  commissions  and fees was  attributable  to a decrease in the
Health Care Division and the closing of Ketchum Sales  Promotions,  an operating
division which comprised less than 1% of consolidated  commissions and fees, due
to continued  operating  losses in 1995. The impact of closing this division was
immaterial with respect to consolidated results of operations. Reduced operating
losses in the Health Care  Division were offset by increased  losses  associated
with increased  activity of the Interactive  Media Unit which was formed in 1994
for the purpose of serving existing and new clients in the emerging  interactive
technology market,  primarily  associated with the Internet.  The improvement in
the Health  Care  Division  in 1995  reflected  a  recovery  from very poor 1994
results.  The 1994 results were adversely  impacted by an industry wide trend of
reduced  advertising  expenditures  by  pharmaceutical  companies as a result of
public scrutiny of these companies'  spending practices.  Directory  Advertising
operating income was comparable in 1995 and 1994.
    

Performance in 1994 compared to 1993

   
      Commissions  and fees for 1994  decreased  to $124.1  million  from $129.5
million in 1993. The decrease was primarily  attributable  to the impact of lost
commissions and fees due to restructuring  which occurred in the last quarter of
1993 and  involved  the closing of certain  offices  during  1994.  Decreases in
commissions  and fees in the other  divisions,  also  contributed to the overall
decrease.  Partially  offsetting  these  decreases was an increase in the Public
Relations Division's commissions and fees.
    

                                       38
<PAGE>

   
     Operating  income in 1994 was $6.6 million compared to an operating loss of
$5.1 million in 1993.  The $11.7 million  change is comprised of a $17.1 million
decrease  in total  operating  expenses  partially  offset  by the $5.4  million
decrease in  commissions  and fees.  With  respect to the  decrease in operating
expenses,  $6.6 million of the decrease represents decreases in compensation and
employee  benefits and general agency expense  related to the closure of offices
as discussed  below.  Results of operations in 1993 were negatively  impacted by
charges of $8.8 million  related to  restructuring.  The  restructuring  was the
result of a Board of Directors decision, made in 1993, to sell the operations in
Philadelphia  (both  public  relations  and  advertising);  close  the New  York
advertising  operation  or partner it with  another  agency in New York;  and to
conditionally  continue the Chicago  advertising  and New York sales  promotions
operations. All of these operations were related to acquisitions made by Ketchum
to obtain a  presence  in a city for the  first  time or to  increase  Ketchum's
presence which formerly had been insignificant.  The reasons for the decision to
restructure  were  primarily  related to poor results of these  operations for a
number of years,  but more  specifically  the  magnitude of losses in 1993. As a
result of this  restructuring,  a write down of $6.0  million of the excess cost
over the fair value of net assets acquired was recorded.  Additionally there was
a $1.9 million lease abandonment charge recorded in connection with vacating the
Philadelphia  office  space  upon  the  sale of the  operations  as well as $0.4
million in  severance  pay covering 53 people in the  Philadelphia  and New York
advertising  operations,  all  of  which  was  paid  during  1994.  Philadelphia
operations were sold during the first quarter of 1994 and New York  Advertising,
through Ketchum New York  Advertising  Holdings,  Inc., was partnered with Jerry
Inc.  to form  Jerry &  Ketchum  during  the  second  quarter  of 1994.  Chicago
Advertising  was ultimately sold in 1995 and New York sales promotion was closed
during 1995.  The final portion of the $8.8 million  restructuring  charge was a
$0.5 million write-off of the net book value of computer  equipment no longer in
use. All  significant  aspects of the  restructuring  had been completed  during
1995. The effect of these 1993  restructuring  charges was to increase operating
income by $1.1 million in 1994.

     In 1993, operating expenses were negatively impacted by $2.0 million, which
included a charge of $0.9 million  related to the write-off of a note receivable
from an equity investee in France.  The note was determined to be  uncollectible
as a result of the investee's  poor financial  condition and negative cash flows
in recent years.  $0.7 million of the $2.0 million impact  represented the write
down of the equity  investment in the same French  operation,  which  management
believed to be necessary, based on past results of operations and projections of
future results.  The remaining $0.4 million primarily  represented the write-off
of excess of cost over the fair  value of net  assets  acquired  of an  inactive
operation in the Netherlands  that was determined to no longer be useful for the
purpose it was originally  intended.  Improved  results of the Public  Relations
Division  and  reduced   losses  of  the  offices   which  were  closed  in  the
restructuring contributed to improved results of operations in 1994.

      Net  income  in 1994 was  $2.1  million  compared  with a net loss of $5.5
million in 1993. Partially offsetting the factors affecting operating income was
an increased effective tax rate due to additional  contingency reserves recorded
for probable specific federal and state exposures in open tax years.
    

      The discussion of results of operations of the operating  divisions  which
follows excludes the impact of other operating expense and restructuring charges
which were discussed above.

     Commissions  and fees for the  Advertising  Division  were $61.4 million in
1994 compared with $65.4 million in 1993. Operating income for the corresponding
periods  was $5.4  million  and $2.6  million,  respectively.  The  decrease  in
commissions and fees was  attributable  to lost  commissions and fees associated
with closing the  Philadelphia  and New York offices.  This impact was partially
offset by an increase in commissions and fees  attributable to expanded business
in the  Advertising  Division's  production  units which allowed the division to
better serve existing  clients and to capture revenues that had gone outside the
agency.  This expansion included new technology which allowed the division to do
typesetting  internally.  Operating  income  increased  primarily due to reduced
losses related to offices which were closed.

     Commissions and fees of the Public  Relations  Division  increased to $45.0
million in 1994 from $41.9 million in 1993 while operating  income  increased to
$2.9  million  from $2.7  million.  The  increase  in  commissions  and fees was
primarily  due to strong  demand for  services in the United  States,  both from
existing clients and new clients.  Commissions and fees related to an additional
investment in an agency in France also contributed to the increase. The increase
in  operating  income  was a  result  of the  factors  that  contributed  to the
commissions and fees increase. The operating profit percentage was approximately
6.4% for both 1994 and 1993.

                                       39
<PAGE>

   
     Commissions  and fees for the other  divisions  were $17.7  million in 1994
compared to $22.2 million in 1993.  Operating  loss was $1.4 million in 1994 and
operating  income was $0.4 million in 1993. The decrease in commissions and fees
was due to the  impact  of lost  commissions  and  fees  in both  the  Directory
Advertising and Health Care Divisions. The decrease in Directory Advertising was
primarily  related to the loss of a  significant  client.  The  decrease  in the
Health Care  Division was due to an industry  wide trend of reduced  advertising
expenditures by pharmaceutical companies as a result of public scrutiny of these
companies' spending practices.  Operating income was negatively impacted by lost
revenues and costs  associated  with a severe  decline in business in the Health
Care Division. Directory Advertising operating income was comparable in 1994 and
1993.
    

Impact of Inflation

     Ketchum's  financial  statements  are prepared on a  historical  cost basis
which does not  completely  account for the effects of inflation.  The impact of
inflation on the Ketchum's  results was not  significant in 1995,  1994 and 1993
due to the low inflation rates in those years.

Accounting Standard

     In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No.121 "Accounting for the Impairment of
Long-Lived  Assets and  Long-Lived  Assets to Be Disposed  Of". This standard is
effective for years beginning after December 15, 1995. The general  requirements
of SFAS  No.121  apply  to  non-current  assets  and  require  impairment  to be
considered  whenever evidence suggests that future cash flows will not result in
an amount at least  equal to the  carrying  value of the asset.  Ketchum has not
adopted  SFAS No. 121 at  December  31,  1995.  Management  of Ketchum  does not
believe the adoption of this standard  will have a material  effect on financial
condition or results of operations.

                         Capital Resources and Liquidity

   
     Cash and cash  equivalents  increased  to $2.9 million from $2.5 million in
1994.  Ketchum's  primary source of cash and cash  equivalents has  historically
been from operations.  Cash flow from operations was $8.1 million,  $6.0 million
and $7.8 million in 1995, 1994 and 1993, respectively. Cash and cash equivalents
have been utilized to fund investing activities,  primarily capital expenditures
and additional  investments in affiliates  and  acquisitions.  Cash flow used in
investing  activities  totaled  $3.5  million,  $7.4 million and $6.3 million in
1995,  1994 and 1993,  respectively.  Ketchum also had available $7.0 million of
capacity,  net of a $1 million  reserve  against  guarantees,  on its  revolving
credit  agreement  at December  31,  1995.  However,  as a result of  additional
borrowings  subsequent to December 31, 1995 Ketchum had approximately $80,000 of
additional  borrowings  available  as of  March  6,  1996.  Ketchum  is  also in
violation of certain covenants of this revolving credit agreement as of March 6,
1996. At December 31, 1995,  Ketchum was also in violation of certain  covenants
pertaining to its senior notes payable;  specifically,  requirements  related to
Ketchum's current ratio, debt to capitalization ratio,  calculated  consolidated
net worth,  fixed charge  coverage  ratio and  interest  coverage  ratio.  Other
violations  included  exceeding the limitations for other minority  investments,
other  investments  and  permitted  debt of  subsidiaries.  As a result of these
covenant  violations,  the holder of the notes may call the debt and declare the
entire amount of the  indebtedness and a penalty,  due and payable  immediately.
The total amount  outstanding  on the notes is  approximately  $11.6 million and
management estimates the penalty, if the note would be called, would approximate
$1.5 million.  Ketchum has had several  discussions  with the senior note holder
concerning the covenant violations. In these discussions, the senior note holder
has not disclosed its intentions  concerning calling the notes.  Ketchum is also
required  to  currently  pay $4.0  million  related  to a  judgment  for a prior
acquisition in the United Kingdom. These factors contribute to a working capital
deficiency at December 31, 1995.

      The report of  Ketchum's  independent  auditors  includes  an  explanatory
paragraph  expressing  substantial doubt regarding Ketchum's ability to continue
as a going  concern.  Note 2 to Ketchum's  financial  statements  describes  the
conditions that give rise to the going concern uncertainty. In response to these
conditions,  management has initiated  discussions with its principal lender and
has also  contacted  another  lender  regarding  the  possibility  of  obtaining
financing.  In addition,  Ketchum has negotiated a possible  merger with Omnicom
which  management  believes  will be  finalized.  Management  believes  that the
financial  strength  of Omnicom,  pending  closing of the deal,  the  reasonable
    

                                       40
<PAGE>

   
probability   related  to  refinancing   long-term   debt,  the  relief  of  the
repurchasing  obligation  of shares of Ketchum  Common  Stock as a result of the
Merger and increased future  profitability  resulting from recent  restructuring
and impairment  charges,  will address Ketchum's current and long-term liquidity
needs.

     Cash and cash  equivalents  have been generated by Ketchum from the sale of
common stock to employees including payments received on related notes.  Ketchum
also has agreements to repurchase Ketchum Common Stock and has utilized cash and
cash equivalents to repurchase shares and to pay related notes.  Under Ketchum's
shareholder agreements, the Ketchum Common Stock is both sold and repurchased by
Ketchum at a price  determined  by a formula  based  primarily  upon book value,
adjusted for certain  items  determined  by the Board of  Directors.  The Common
Stock  of  Ketchum  is  owned by the  employees  and  Ketchum  is  obligated  to
repurchase its common stock from the holders upon termination of employment. The
total repurchase  obligation is recorded based upon the formula price and number
of shares  outstanding  at each balance  sheet date.  At Ketchum's  option these
repurchases  are paid  either by cash in a lump sum or over a three to five year
period. In 1994 and 1993 Ketchum issued 20,000 shares of Ketchum Preferred Stock
to generate additional cash and cash equivalents. The Ketchum Preferred Stock is
held only by the Ketchum Profit Sharing Plan. Ketchum has paid cash dividends on
common and preferred shares of approximately  $0.6 million in each of 1995, 1994
and 1993.

     In order to provide  sufficient  cash flow from operating  activities it is
the  policy of  Ketchum  to bill in advance  of  payments  due for  services  it
provides  as often as  possible in order that cash  receipts  can closely  match
payment requirements.  All general advertising broadcast media and substantially
all general advertising print media costs are invoiced in the month in which the
commercial  airs or the ad is  inserted.  Directory  advertising  costs  are all
billed any where from 0 to 4 months in  advance of when a  directory  is issued.
Production  costs are generally  billed in advance under the installment  method
based on estimated costs of the work to be performed.

     Management  of Ketchum  believes  that due to the  renewed  efforts of cost
cutting and cost  containment  used in developing the 1996 plan,  which projects
increased  profits,  sufficient  taxable  income  will be  generated  in 1996 to
realize the net  deferred tax asset  recorded at December  31, 1995.  Management
believes the 1996 plan and the  assumptions  underlying  it are  reasonable  and
believes  it is more  likely  than not  that  the  deferred  tax  asset  will be
realized.

                      DESCRIPTION OF OMNICOM CAPITAL STOCK

     Each share of Omnicom  Common Stock entitles the holder thereof to one vote
on all matters submitted to a vote of shareholders. All shares of Omnicom Common
Stock have equal rights and are entitled to such dividends as may be declared by
the Omnicom Board of Directors out of funds  legally  available  therefor and to
share  ratably upon  liquidation  in the assets  available for  distribution  to
stockholders.  Omnicom is not aware of any restrictions on its present or future
ability  to  pay  dividends.  However,  in  connection  with  certain  borrowing
facilities  entered into by Omnicom and its subsidiaries,  Omnicom is subject to
certain restrictions on current ratio, ratio of total consolidated  indebtedness
to total  consolidated  capitalization,  ratio of net cash flow to  consolidated
indebtedness,  and  limitation of  investments  in and loans to  affiliates  and
unconsolidated subsidiaries.  The Omnicom Common Stock is not subject to call or
assessment,  has no preemptive conversion or cumulative voting rights and is not
subject  to  redemption.  Omnicom's  shareholders  elect a  classified  board of
directors,  and may not remove a director  except by an  affirmative  two-thirds
vote of all outstanding shares. A two-thirds vote is also required for Omnicom's
shareholders  to amend  Omnicom's  by-laws or certain  provisions of its charter
documents, and to change the number of directors comprising the full board.

     Omnicom may issue  preferred  stock in series  having  whatever  rights and
preferences the Omnicom Board of Directors may determine.  One or more series of
preferred  stock may be made  convertible  into  Omnicom  Common  Stock at rates
determined by the Board of Directors,  and preferred stock may be given priority
over the Omnicom  Common Stock in payment of dividends,  rights on  liquidation,
voting and other  rights.  Preferred  stock may be issued from time to time upon
authorization  of  the  Omnicom  Board  of  Directors   without  action  of  the
shareholders, Omnicom has no current plans to issue any preferred stock.

     Omnicom  currently  has  outstanding  $143,750,000  of  4.5%/6.25%  Step-Up
Convertible Subordinated Debentures with a scheduled maturity in 2000, which are
convertible into Omnicom Common Stock at a conversion  price of $27.44,  subject
to adjustment in certain events.

     Chemical Mellon Shareholder  Services,  450 West 33rd Street, New York, New
York 10001 is the transfer agent and the registrar of the Omnicom Common Stock.

                      DESCRIPTION OF KETCHUM CAPITAL STOCK

   
     Ketchum is a  privately-owned  company and there is no  established  public
trading market for its capital stock.  Ketchum's authorized capital is 2,000,000
shares of common  stock,  stated value of $0.005 per share and 50,000  shares of
preferred  stock,  par value $100 per share.  As of April 15,  1996,  there were
358,818  shares of Ketchum  Common Stock issued and  outstanding  and  1,005,182
shares of Ketchum  Common Stock held in  treasury;  and 6,282 shares of Series A
Preferred Stock issued and outstanding and no shares of Series A Preferred Stock
held in treasury.
    

      Under provisions of the Ketchum Articles, only (a) employees of Ketchum or
an entity owned by Ketchum, or in which Ketchum, directly or indirectly,  has an
interest, (b) non-employees approved by the Ketchum Executive Committee, and (c)
a trust(s)  established as a part of a qualified  retirement  plan maintained by
Ketchum,  are entitled to become  shareholders  of Ketchum.  No more than 10% of
Ketchum's issued and outstanding capital stock can be owned by non-employees and
employees of entities which are less than 100% owned by Ketchum or a corporation
owned directly or indirectly by Ketchum.

     Shares of stock held by  employees  of Ketchum  are subject to the terms of
shareholder agreements, which restrict the sale, transfer, pledge, hypothecation
or  other  disposition  of  shares.  Pursuant  to  the  shareholder  agreements,
transfers of shares are prohibited  except to Ketchum or to other employees upon
Ketchum's approval.  An employee, or his estate, is obligated to sell his shares
to Ketchum upon termination of employment, death or bankruptcy. Those shares are
repurchased by Ketchum at a price to be determined in accordance  with the terms
of the shareholder  agreement.  This  determination is based primarily upon book
value, as adjusted by the Ketchum Board of Directors.

Common Stock

     All  outstanding  shares  of  Ketchum  Common  Stock  are  fully  paid  and
nonassessable.  The holders of Ketchum Common Stock are entitled to one vote for
each share held of record and on all matters voted by the Ketchum  Shareholders.
There are no cumulative voting rights for the election of directors.

                                       42
<PAGE>

     There are no redemption, sinking fund, conversion or preemptive rights with
respect to shares of Ketchum  Common Stock.  All shares of Ketchum  Common Stock
have equal rights and  preferences.  In the event of the liquidation of Ketchum,
each  outstanding  share is  entitled  to  participate  pro  rata in the  assets
remaining  after payment of, or adequate  provision  for, all known  preferences
(including the Ketchum Preferred Stock), debts and liabilities of Ketchum.

     Dividends  are payable  only when and if declared by the Board of Directors
of Ketchum out of funds legally available therefor and are necessarily dependent
upon  earnings,  the general  financial  status of the company and various other
factors.  A small cash dividend was historically paid with respect to the shares
of Ketchum  Common  Stock so as to  preserve  corporate  funds for growth and to
increase the potential for long-term capital gain treatment. The regular Ketchum
Common Stock  dividend has been paid in four equal  quarterly  installments.  In
1994 and 1995,  a $1.00  dividend  was paid with  respect to the Ketchum  Common
Stock. A special Ketchum Common Stock dividend is paid only if actual  financial
performance is substantially above projected performance,  and only if Ketchum's
capital  requirements  do not require  retention of the cash. No special Ketchum
Common Stock dividend has been declared in the past five years.

Preferred Stock

     Ketchum has designated 20,000 shares of Series A Preferred Stock, par value
$100 per share, as a series of its authorized  preferred stock; this is the only
preferred stock  outstanding and is referred to in this document as the "Ketchum
Preferred  Stock".  The  Ketchum  Preferred  Stock has a  dividend,  if and when
declared by the Ketchum Board of Directors,  of $90 per annum per share, payable
in quarterly payments of $22.50 on March 15, June 15, September 15, and December
15 of each year. Such dividends are senior to dividends on Ketchum Common Stock,
and are cumulative  and accrue on a day-to-day  basis whether or not earned from
and after the date of  issuance or the date to which  dividends  have been paid.
Accrued but unpaid  dividends do not bear interest.  The quarterly  dividends on
the Ketchum  Preferred Stock as described above were paid by Ketchum as required
for each quarter of 1994 and 1995.

     Late dividends (those paid on the 30th or following date after the dividend
payment  date)  accrue  at the rate of $100 per  annum  for a period  of 90 days
following such dividend payment date, and $90 per annum thereafter.  The Ketchum
Preferred Stock has a liquidation  preference over the holders of Ketchum Common
Stock of $1,000,  plus all  accrued but unpaid  dividends,  per share of Ketchum
Preferred Stock. Except for such liquidation preference,  the holders of Ketchum
Preferred  Stock  are not  entitled  to any  distribution  in the  event  of the
liquidation,  dissolution or winding up of Ketchum. If the assets of Ketchum are
not  sufficient  to pay such  liquidation  preference,  the  holders  of Ketchum
Preferred  Stock share ratably in any such  distribution  in accordance with the
amount  that would have been paid if such  liquidation  preference  were paid in
full. After the liquidation preference is paid in full, all remaining assets are
to be distributed to the holders of the Ketchum Common Stock.

      Ketchum may redeem the Ketchum  Preferred  Stock at any time after January
1, 2003 at the option of the Ketchum Board of Directors, in whole or in part, at
a redemption  price of $1,045 per share of Ketchum  Preferred Stock plus accrued
and unpaid dividends to the redemption date.

     Each  share of  Ketchum  Preferred  Stock has one vote,  which  shall  vote
together with the Ketchum  Common Stock on all matters  submitted to the Ketchum
Shareholders,  except for  matters,  such as the  Merger,  as to which the PABCL
provides for a special class vote.

                        COMPARISON OF SHAREHOLDER RIGHTS

     Upon   consummation  of  the  Merger,   the  shareholders  of  Ketchum,   a
Pennsylvania  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
Ketchum  Shareholders  that will result from the  application of New York law in
lieu of Pennsylvania law and the differences between the Omnicom Certificate and
the Omnicom  By-laws  and the Ketchum  Articles  and the  Ketchum  By-laws  (the
"Ketchum By-Laws"), the following is a summary of material differences.


                                       43
<PAGE>

      References  to the "NYBCL" are to the New York Business  Corporation  Law,
while  references to the "PABCL" are to the  Pennsylvania  Business  Corporation
Law.

Special Meetings of Shareholders

     The PABCL provides that a special meeting of the shareholders may be called
at any time by the board of directors, by such other officers and persons as may
be provided in the by-laws of the  corporation,  or by shareholders  entitled to
cast at least 20% of the votes which all  shareholders  are  entitled to cast at
such  a  meeting.  The  Ketchum  By-laws  provide  that  a  special  meeting  of
shareholders  may be  called  at any  time by the  Chairman  of the  Board,  the
President, any Vice Chairman of the Board, the Secretary, the Board of Directors
or the holders of not less than ten percent of all  outstanding  shares entitled
to vote at the special meeting.  Under the Ketchum By-laws,  if the Secretary of
Ketchum  fails to schedule a special  meeting of the  shareholders  after such a
meeting had been requested by a person or persons  entitled to do so, the person
or persons making the request for a special meeting may schedule the meeting.

     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.

Removal of Directors

     Under Pennsylvania law, the entire board of directors, a class of the board
of directors or any individual  director may be removed  without cause by a vote
of the shareholders entitled to vote for the election of directors. Further, the
board of directors  may be removed at any time,  with or without  cause,  on the
unanimous vote or consent of the shareholders. The Ketchum By-laws are otherwise
silent as to the removal of directors.

     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 such Shares are 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

     Pennsylvania  law  provides  that  vacancies  on the  board  of  directors,
including  vacancies  resulting from an increase in the number of members of the
board of directors, may be filled by a majority vote of the remaining members of
the board of directors,  even if the remaining  members  constitute  less than a
quorum.  The PABCL also states  that the person  selected to fill the vacancy on
the board of  directors  then  serves the balance of the  unexpired  term on the
board.  The Ketchum  By-laws  provide  that a vacancy on the Board of  Directors
shall be filled by a  majority  vote of the  remaining  directors,  even if they
comprise  less  than a quorum.  Under the  Ketchum  By-laws,  the newly  elected
director then serves until the next annual meeting of the shareholders and until
a  successor  is elected and  qualified  or until the newly  elected  director's
earlier death, resignation or removal.

     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


                                       44
<PAGE>

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

     The Ketchum By-laws do not provide for the  classification  of the Board of
Directors.

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

Inspection of the Books and Records

     Under  Pennsylvania  law, a  shareholder  has the right to examine,  during
normal business hours,  the share register,  the books and records of account of
the corporation,  the records of proceedings of the incorporators,  shareholders
and directors,  and to make copies and extracts  therefrom,  if the  shareholder
makes a written,  verified demand to inspect.  The shareholder's  written demand
must  state a purpose  for the  inspection  that is  reasonably  related  to the
shareholder's  status as a  shareholder.  If the  inspection is to be made by an
attorney  or agent of the  shareholder,  the  demand  must be  accompanied  by a
verified power of attorney authorizing the attorney or agent to act on behalf of
the  shareholder.  If the  corporation or an officer or agent of the corporation
has refused to permit the inspection or does not reply to the demand within five
business days after the demand was made, the  shareholder may apply to the court
of common  pleas to  enforce  the right of  inspection,  and the court of common
pleas will determine if the inspection is being made for a proper purpose. Other
than  specifically  enumerating  the  shareholders'  rights  to  receive  annual
financial  statements,  the Ketchum By-laws do not otherwise refer to the rights
of shareholders to inspect the corporate books and records.

     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 Articles of Incorporation/Certificate of Incorporation

     Pennsylvania  law states that  amendments to the articles of  incorporation
shall be  proposed by  resolution  of the board of  directors  or by petition of
shareholders  entitled  to cast at least ten  percent of the shares  entitled to
vote.  The board of  directors  must  provide a summary or copy of the  proposed
amendment and information  regarding  dissenters' rights, if applicable,  to the
shareholders.   Except  in  limited   cases,   amendments  to  the  articles  of
incorporation must be approved by a majority of shares entitled to vote and by a
majority  of any  class or  series of  shares  that is  entitled  to vote on the
proposed  amendment as a class or series.  Certain amendments to the articles of
incorporation that would adversely affect a series or class or which would alter
the preferences of a series or class also must be approved by a majority vote of
that  series  or  class.  The  Ketchum  By-laws  do not  otherwise  provide  for
amendments to the Articles of Incorporation.

     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

      Pennsylvania law provides that the shareholders have the power to amend or
repeal the by-laws of the corporation. However, the power to amend or repeal the
by-laws  can be  expressly  vested by the  by-laws  in the  board of  directors,
subject to the power of the shareholders to change such action by the board. The
Ketchum By-laws provide that the By-laws may be amended or altered by a majority

                                       45
<PAGE>

vote of the members of the Board of Directors at any regular or special meeting,
subject to the power of the  shareholders  to change such action by the Board of
Directors.

     Under  Pennsylvania  law, the board of  directors  lacks the power to amend
by-laws  relating  to a variety  of  subjects  that can be  amended  only by the
shareholders,  including  provisions  governing  the  powers  of  the  board  of
directors, limiting the personal liability of members of the board of directors,
classification  of the board of directors,  removal of directors and quorums and
certain other matters relating to shareholder meetings.

     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

     Under Pennsylvania law and unless the by-laws state otherwise, the board of
directors is empowered to authorize  distributions  to or for the benefit of its
shareholders.  The PABCL  prohibits a distribution  if, after it is made (i) the
corporation  would be unable to pay its debts as they become due in the ordinary
course of business  or (ii) the total  assets of the  corporation  would be less
than the sum of (A) its  total  liabilities  and (B) the  amount  that  would be
needed,  if the  corporation  were to be  dissolved  at the time as of which the
distribution is measured, to satisfy the preferential rights upon dissolution of
the shareholders whose  preferential  rights are superior to those receiving the
distribution.

      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

     In certain instances,  Pennsylvania's  takeover  legislation  restricts the
ability of a person or entity to acquire  control of a Pennsylvania  corporation
through  a  business  combination,  such as a  merger,  consolidation  or  share
exchange,  or through the  acquisition  of shares  constituting  at least twenty
percent  of the  votes  that can be cast in the  election  of  directors  of the
corporation.  The  takeover  provisions  of the PABCL  apply,  however,  only to
registered corporations,  which are defined as (i) those corporations which have
registered  securities under the Exchange Act, (ii) those corporations that have
reporting  requirements under the Exchange Act by virtue of a registration filed
under the Securities Act, (iii) certain  corporations  that have registered as a
management  company  under  the  Investment  Company  Act  of  1940  or  (iv)  a
Pennsylvania  corporation  all of whose  shares are owned,  either  directly  or
indirectly, by a domestic or foreign registered corporation. Because Ketchum has
no  reporting  or  registration  requirements,  is not a  registered  management
company  and is not owned,  either  directly  or  indirectly,  by a domestic  or
foreign  registered  corporation,   the  Pennsylvania  takeover  legislation  is
inapplicable to Ketchum.

     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


                                       46
<PAGE>

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.

      Under the NYBCL,  corporations  may opt to not be governed by the statute;
Omnicom has not so elected.

Business Combinations

     Under the PABCL,  the affirmative  vote of the holders of a majority of the
outstanding shares entitled to vote on the matter is required to approve mergers
or consolidations,  and certain sales, leases, exchanges and other distributions
of all or  substantially  all of the  property and assets of a  corporation.  In
addition,  if any class or series of shares is entitled to vote on the merger or
consolidation  as a  class,  a  majority  of the  votes  cast in each  class  is
necessary to approve the merger or consolidation.

     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

     Under Pennsylvania law, a shareholder can dissent from, and receive payment
of the  fair  value of his or her  shares  in the  event  of,  certain  mergers,
consolidations,  share  exchanges,  asset  transfers  and  corporate  divisions.
Further,  a  corporation  may, in its by-laws or by  resolution  of the board of
directors,  provide for  dissenters'  rights that are more  expansive than those
granted by the PABCL.  Neither  the Ketchum  By-laws  nor any board  resolutions
provide for any such expanded  dissenters'  rights.  A shareholder who wishes to
dissent  from a  corporate  action and to  receive  the fair value of his or her
shares must (i) make a written demand therefor prior to the shareholder  vote on
the action,  (ii) retain  ownership of the shares  through the effective date of
the proposed  action and (iii) refrain from voting his or her shares in approval
of the action.  The shareholder  then must make a demand for payment and deposit
his or her  share  certificates  with the  corporation  within  the time  period
allotted by the  corporation.  If the shareholder  fails to make a timely demand
for  payment or fails to deposit  stock  certificates  with the  corporation  in
accordance with  instructions by the corporation,  the shareholder  loses his or
her  right to  receive  payment  for the fair  value of his or her  share  under
Pennsylvania law.

     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

     Absent contrary provisions in the corporation's  by-laws,  Pennsylvania law
provides that a corporation has the power to, and in some cases must,  indemnify
any person who was or is a party,  or is threatened  to be made a party,  to any
threatened,  pending or completed  action or proceeding,  including a derivative
action,  by  reason  of the fact  that the  person  is,  was or  functions  as a
director,  officer, employee or agent of the corporation.  Such indemnification,
against reasonable expenses,  attorneys' fees, judgments, fines and amounts paid
in settlements,  is permitted only if the person to be indemnified 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 or, in the case of a criminal  proceeding,
if he or she had no  reasonable  cause to believe  that his or her  conduct  was
unlawful.

     A determination that the officer,  director,  employee or agent has met the
required standard of conduct, and that indemnification therefore is proper, must
be made (i) by a majority vote of a quorum comprised of disinterested directors,


                                       47
<PAGE>

(ii) in  writing  by  independent  legal  counsel  if a quorum of  disinterested
directors cannot be achieved or, if a quorum of disinterested  directors exists,
a majority of such quorum votes to seek a written  determination  by independent
legal counsel or (iii) by the shareholders.  In the case of a derivative action,
the PABCL bars  indemnification when the representative has been adjudged liable
unless  and to the extent the court of common  pleas or other  court  determines
that indemnity is proper.

     A  corporation  may  advance  expenses  incurred  by a  director,  officer,
employee  or agent in  defending  an  action  or  proceeding  in the  event  the
director,  officer,  employee  or  agent  has  provided  to the  corporation  an
undertaking to repay the advanced  expenses if it is later determined that he or
she  was not  entitled  to  indemnification.  The  PABCL  also  provides  that a
corporation must indemnify a director,  officer, employee or agent from expenses
incurred  in  defense  of any  action or  proceeding  described  above  when the
director,  officer,  employee  or agent  has been  successful  on the  merits or
otherwise.

     The statutory  indemnification rights are not exclusive and can be expanded
by the  corporation's  by-laws,  by agreement or by vote of the  shareholders or
disinterested   directors.   Such  expanded   indemnification   rights  will  be
unavailable,  however,  if a court of common pleas finds that the act or failure
to act giving rise to the purported right of indemnification constituted willful
misconduct  or  recklessness.  Finally,  unless the  by-laws of the  corporation
provide  otherwise,  a  corporation  may  purchase  insurance  on  behalf of any
officer, director, employee or agent.

     The  Ketchum  By-laws  provide  that  indemnification  shall  be  made to a
director or officer to the fullest  extent  permitted  by law for  expenses  and
other costs incurred in any action, suit or proceeding, whether civil, criminal,
administrative or investigative,  and whether or not such suit was derivative in
nature. In addition, the Ketchum By-laws provide that an officer or director may
be  entitled  to  indemnification  in  connection  with a  proceeding  he or she
initiated  only if such  proceeding  was  authorized  by the  Ketchum  Board  of
Directors.

     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
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


                                       48
<PAGE>

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
Ketchum  pursuant to the  foregoing  provisions,  Omnicom and Ketchum  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

     Under  Pennsylvania  law, a by-law adopted by the  shareholders may provide
that, except in the case of responsibility or liability under a criminal statute
or liability for payment of local,  state or federal taxes, a director shall not
be  personally  liable for  monetary  damages  for any action  taken  unless the
director has breached or failed to perform his or her  fiduciary  duties and the
breach or failure to perform  constituted  self dealing,  willful  misconduct or
recklessness.  The  Ketchum  By-laws  provide  that  a  director  shall  not  be
personally  liable for  monetary  damages for any action taken or the failure to
take any action  unless the director  breached his or her  fiduciary  duties and
such breach constituted  self-dealing,  willful  misconduct or recklessness.  In
addition,  the Ketchum  By-laws  provide that such  limitations  on the personal
liability of directors does not extend to liability under a criminal  statute or
for the liability for payment of taxes under local, state or federal law.

      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,  which  Section  establishes  liability  of  directors  of a
corporation  to that  corporation  in the event  that they  approve  statutorily
prohibited  dividends,  share repurchases,  share redemptions,  distributions of
assets on dissolution or loans to directors.
    

                                  LEGAL MATTERS

     The  legality of the  issuance of the Omnicom  Common Stock to be issued in
the Merger will be passed upon by Davis & Gilbert, 1740 Broadway,  New York, New
York 10019, counsel to Omnicom.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors of
Ketchum Communications Holdings, Inc.:

     We have audited the  accompanying  consolidated  balance  sheets of Ketchum
Communications Holdings, Inc. and subsidiaries as of December 31, 1995 and 1994,
and the related consolidated statements of operations,  redeemable preferred and
common stock and accumulated deficit, and cash flows for each of the three years
in the period ended  December  31,  1995.  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,  such consolidated  financial statements present fairly, in
all  material  respects,   the  financial  position  of  Ketchum  Communications
Holdings,  Inc.  and  subsidiaries  as of December  31,  1995 and 1994,  and the
results of their  operations and their cash flows for each of the three years in
the period  ended  December  31,  1995 in  conformity  with  generally  accepted
accounting principles.

     The  accompanying  consolidated  financial  statements  have been  prepared
assuming that the Company will continue as a going concern.  As indicated in the
accompanying consolidated financial statements,  the Company incurred a net loss
for  the  year  ended  December  31,  1995  and  has  an  accumulated   deficit.
Additionally,  as  discussed in Note 2, the Company was not in  compliance  with
certain  terms of a long-term  debt  agreement at December  31,  1995,  and as a
result,  the  holder of the debt has the right to declare  the entire  amount of
such  indebtedness  and a penalty,  due and  payable  immediately.  Further,  as
described in Note 14, the Company has lost a judgement  which will require it to
pay approximately  $4,000,000 currently and, as described in Note 6, as a result
of  borrowings  subsequent to December 31, 1995,  the Company has  approximately
$80,000 of available borrowing capacity and is in violation of certain covenants
under its revolving credit agreement as of March 6, 1996. These conditions raise
substantial  doubt about the Company's  ability to continue as a going  concern.
Management's  plans  concerning  these matters are also described in Note 2. The
accompanying  consolidated  financial  statements do not include any adjustments
that might result from the outcome of this uncertainty.

     As discussed in Note 1 to the consolidated financial statements,  effective
January 1, 1993, the Company changed its method of accounting for income taxes.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                  Years ended December 31, 1995, 1994 and 1993


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     a. Principles of  Consolidation -- The  consolidated  financial  statements
include the accounts of Ketchum Communications  Holdings, Inc. ("Ketchum" or the
"Company") and subsidiaries,  U.S. and non-U.S., for which ownership exceeds 50%
of the voting  stock.  Investments  in companies  ranging from 20% to 50% of the
voting stock are carried at equity, and a proportionate share of the earnings or
losses of such equity  investees is included in the  statements  of  operations.
Transactions   between   Ketchum  and  its   subsidiaries   are   eliminated  in
consolidation.

     b. Use of  Estimates in the  Preparation  of  Financial  Statements  -- The
preparation  of financial  statements  in  conformity  with  generally  accepted
accounting principles requires management to make estimates and assumptions that
affect the reported  amounts of assets and  liabilities  and the  disclosure  of
contingent  assets and liabilities at the date of the financial  statements,  as
well as the reported amounts of income and expenses during the reporting period.
Actual results could differ from those estimates.
  
     c. Cash Equivalents -- The Company considers all highly liquid  investments
purchased  with  an  original  maturity  of  three  months  or  less  to be cash
equivalents.

     d. Revenue  Recognition -- Revenue is derived from commissions and fees for
production and placement of  advertising,  public  relations,  sales  promotion,
research and other services.  Depending upon the nature of the service,  revenue
is recognized  in the month in which  advertisements  appear,  when services are
rendered or when costs are incurred.

     e.  Billable  Production  in  Process  --  Billable  production  in process
includes  outside  services  and  materials  plus  commissions  and fees,  where
applicable,  and the value of internal time incurred and are stated at the lower
of accumulated charges or estimated realizable amounts.

     f. Depreciation and Amortization of Property and Equipment -- Furniture and
equipment are depreciated on the straight-line basis over their estimated useful
lives which range from five to ten years.  Leasehold  improvements are amortized
on the  straight-line  basis over the shorter of the lives of the related leases
or the  estimated  useful lives of the  improvements,  which range from three to
twenty years.

      Included in property and  equipment are leased assets at December 31, 1995
and 1994 of $1,136,800 and $2,470,700, respectively. Leased assets are amortized
on the straight-line basis over the lives of the related leases which range from
three to five years.  Accumulated amortization at December 31, 1995 and 1994 was
$495,700 and $916,400, respectively.

   
     g. Excess of cost over fair value of net assets  acquired -- The  Company's
policy is to periodically  evaluate the carrying value of the excess of the cost
over the fair  value of net assets of  businesses  acquired  based on  estimated
future results of operations and cash flows of the related subsidiaries.
    

     The excess of cost over fair value of net assets of businesses  acquired is
amortized  on the  straight-line  method  over the  expected  periods  of future
benefit, which range from five to twenty years.

   
      In March 1995, the Financial  Accounting  Standards Board issued Statement
of Financial Accounting Standard ("SFAS") No. 121 "Accounting for the Impairment
of Long-Lived Assets and Long-Lived Assets to Be Disposed Of." This statement is
effective for years beginning after December 15, 1995. The general  requirements
of SFAS No.  121  apply to  non-current  assets  and  require  impairment  to be
considered  whenever  evidence suggests that future cash flows will not at least
equal the carrying value of the asset.  Goodwill not associated  with long-lived
assets or  identifiable  intangibles is excluded from the scope of SFAS No. 121.
Ketchum has not adopted SFAS No. 121 at December 31, 1995.  Management  does not
believe  the  adoption  of this  standard  will  have a  material  impact on the
Company's financial condition or the results of its operations.
    

     h. Income Taxes -- Effective  January 1, 1993, the Company adopted SFAS No.
109,  "Accounting for Income Taxes." The Company had previously  recorded income
taxes in accordance with SFAS No. 96,  "Accounting  for Income Taxes."  Deferred
income taxes  reflect the future tax  consequences  of  differences  between the
financial  reporting  and tax  reporting  bases of assets and  liabilities.  The
cumulative effect of this 1993 change in accounting principle was insignificant.
The change had no effect upon 1993 results of operations.

     i. Foreign Currency  Translation -- The Company translates foreign currency
assets and  liabilities  using the exchange rates in effect at the balance sheet
date.  Results of operations  are  translated  using the average  exchange rates
prevailing  throughout  the year.  Translation  adjustments  are  deferred  as a
separate component in accumulated deficit.

      j. Net  (Loss)  Income Per  Common  Share -- Net (loss)  income per common
share is based on net (loss) income after  dividends on preferred  stock and the
weighted average number of common shares outstanding during the year.
The Company does not have common stock equivalents.
 
     k.  Investments -- Effective  January 1, 1994 the Company  adopted SFAS No.
115,  "Accounting  for Certain  Investments  in Debt and Equity  Securities"  to
account  for its  investments.  This  statement  expands  the use of fair  value
accounting for certain investments while retaining the amortized cost method for
investments in certain debt securities  based on a company's  intent and ability
to hold the investments to maturity. The adoption of this standard had no effect
upon 1994 results of operations.

     The Company's  investments consist primarily of certificates of deposit and
marketable  equity  securities.  The marketable equity securities are classified
based on SFAS No. 115 as "available-for-sale" and are stated at market value. At
December  31, 1995 the  carrying  value of all  investments  approximates  their
market value. The aggregate carrying value and market value of marketable equity
securities  at  December  31,  1994  was  $504,301  and  $15,000,  respectively.
Unrealized  holding losses of $489,301 net of deferred  taxes,  including a 100%
tax asset  valuation  allowance  of $201,380,  was  included in the  accumulated
deficit  section of the  consolidated  balance  sheet at December 31, 1994.  The
market value of other investments at December 31, 1994 approximated cost.
 
   
     During 1995 the Company recorded an approximately $500,000 write-down for a
certain  marketable  equity  security as it was determined  this  investment was
permanently impaired due to what the Company considers to be a permanent decline
in market value and no readily available market for sale.
    

     l. Financial  Instruments -- The Company's financial instrument  portfolio,
excluding  investments,  consists  primarily  of cash and cash  equivalents  and
short-  and  long-term  debt  instruments.   The  most  significant  instrument,
long-term debt, had a carrying value which  approximated  the fair market value.
The fair market value was  determined  based upon a present  value  technique of
estimating  future cash flows using a discount rate  commensurate with the risks
involved. The fair values of the other instruments approximated carrying value.

2. GOING CONCERN

      The Company  incurred a net loss for the year ended  December 31, 1995 and
has an accumulated deficit. In addition,  the Company was not in compliance with
certain terms of a long-term debt instrument at December 31, 1995 and the holder
of the debt has the right to declare the entire amount of such  indebtedness and
a penalty,  due and payable  immediately (see Note 6). Further,  as described in
Note  14,  the  Company  has  lost a  judgement  which  will  require  it to pay
approximately  $4,000,000  currently and, as described in Note 6, as a result of
borrowings  subsequent  to December  31,  1995,  the  Company has  approximately
$80,000 of available borrowing capacity and is in violation of certain covenants
under its revolving  credit  agreement as of March 6, 1996. As a result of these
factors,  substantial  doubt exists about the Company's ability to continue as a
going concern.  The financial statements have been prepared assuming the Company
will continue as a going concern and do not contain any  adjustments  that might
result from this uncertainty.

   
     In response to these  conditions,  the Company's  management has initiated
discussions  with its principal  lender and has also  contacted  another  lender
regarding the possibility of obtaining  financing.  As discussed in Note 15, the
Company has  negotiated a possible  merger with Omnicom Group Inc.  ("Omnicom"),
which  management  believes  will be  finalized.  Management  believes  that the
financial  strength of Omnicom,  pending the closing of the deal, the reasonable
probability   related  to  refinancing   long-term   debt,  the  relief  of  the
repurchasing  obligation of shares of the Company's  common stock as a result of
the  merger  and   increased   future   profitability   resulting   from  recent
restructuring  and  impairment  charges will address the  Company's  current and
long-term liquidity needs.

3. NATURE OF OPERATIONS

   
     Ketchum is an agency  comprised  of four  autonomous  operating  divisions,
advertising,   public   relations,   directory   advertising  and  health  care.
Advertising  and public  relations  are the  largest  divisions  as  measured by
commissions  and fees.  Ketchum's  primary  operations  are based in the  United
States.  International  operations  comprised 7%, 6% and 5% of total commissions
and fees for the years ended  December  31, 1995,  1994 and 1993,  respectively.
International  assets were  approximately  8% and 6% of total assets at December
31, 1995 and 1994, respectively. Approximately 18% of total commissions and fees
was  attributable  to one major client for each of the years ended  December 31,
1995,  1994  and  1993.  A  portion  of the  business  for  this  major  client,
representing  approximately  3% of total  commissions  and fees on an annualized
basis for the year ended  December 31, 1995,  was lost in the fourth  quarter of
1995.
    

4. IMPAIRMENT OF EXCESS OF COST OVER FAIR VALUE OF NET ASSETS ACQUIRED

   
     As a result of management's  periodic analysis of the recoverability of the
carrying value of the excess of cost over the fair value of net assets acquired,
management  wrote down the carrying  value at December 31, 1995 in the amount of
$2,759,426.  Management's  analysis  was  based on  undiscounted  cash  flows of
expected  future  performance of the related  operations.  Expected  future cash
flows were based upon  internal  projections  considering  past trends,  general
business economic conditions and discussions with key management  personnel.  To
the extent that the cash flows did not support the carrying  value of the excess
of cost over the fair value of net assets  acquired,  write downs were recorded.
The $2.8 million write down relates principally to two domestic operations which
have incurred  significant losses since 1992. $1.1 million of the charge relates
to the  Company's  Public  Relations  Division and $1.4  million  relates to its
Health Care Division.  Prior to 1995,  management believed that these operations
could be turned around.  However,  poor 1995 results of operations and projected
losses led management to conclude that write downs should be made in 1995. There
was no impairment loss in 1994. A similar analysis at December 31, 1993 resulted
in an impairment loss of $340,076.
    

5. OTHER ASSETS

   
     Other assets include approximately $4,111,000 and $3,774,000 of investments
in equity investees at December 31, 1995 and 1994,  respectively.  Approximately
$3,182,000  and  $2,985,000  of the recorded cost at December 31, 1995 and 1994,
respectively,  represents  cost in excess of the  equity in the  underlying  net
assets of these investees. The excess of cost over equity in net assets is being
amortized  on a  straight-line  basis over  periods  ranging from ten to fifteen
years. The Company's share of net loss in equity investees, which is included in
other expense in the consolidated  statements of operations,  was  approximately
$723,273  and  $252,834  for  the  years  ended  December  31,  1995  and  1994,
respectively.  The Company's share of net loss in equity  investees for 1993 was
insignificant.  Notes receivable from certain equity investees have been written
off in 1995 and 1993 (see Note 14). The Company did not receive  dividends  from
equity  investees  in 1995.  The Company  received  dividends  of  approximately
$120,000 and $474,000 in 1994 and 1993, respectively.

     Foreign   subsidiaries   have  outstanding   short-term  notes  payable  of
$1,769,582 and $1,816,117 with a weighted average interest rate of 9.4% and 9.9%
at December 31, 1995 and 1994, respectively.

     The Company has an $8,000,000  revolving  credit agreement which expires on
September 30, 1996, at which time any outstanding balance is due and payable. Of
this amount, approximately $1,000,000 is reserved against guarantees for foreign
credit facilities.  In connection with the agreement, the Company is required to
pay a .5%  commitment  fee on any unused  portion.  No amounts were  outstanding
under the  revolving  credit  agreement at December 31, 1995 and under a similar
agreement at December 31, 1994. As a result of borrowings subsequent to December
31, 1995, the Company has approximately  $80,000 of available borrowing capacity
and is in violation of certain covenants under the revolving credit agreement as
of March 6, 1996.

   
     On August 9, 1994,  the Company  repaid  certain  existing  senior debt and
obtained additional  financing,  via the issuance and sale by the Company of its
9% unsecured senior notes.  The unsecured  senior notes require  compliance with
certain  financial and other  covenants.  The Company was not in compliance with
certain of these  covenants  at December  31,  1995,  specifically  requirements
related to the Company's current ratio, debt to capitalization ratio, calculated
consolidated net worth, fixed charge coverage ratio and interest coverage ratio.
Other   violations   included   exceeding  the  limitations  on  other  minority
investments,  other investments and permitted debt of subsidiaries.  As a result
of these  covenant  violations,  the holder of the senior  notes may declare the
outstanding  amount  of  the  indebtedness  due  and  payable  immediately  and,
accordingly,  the  outstanding  amount of  $11,571,429  has been  classified  as
current in the consolidated balance sheet at December 31, 1995. If the holder of
the senior notes were to call the notes,  an early payment penalty would be due,
which  management  of the Company  estimates to be  approximately  $1,529,000 at
March 6, 1996.  In  management's  opinion,  it is  reasonably  possible that the
holder will call the notes and assess the penalty.  No  provision  has been made
for any penalty that might ultimately be assessed.

     Interest paid was approximately  $1,963,000,  $2,796,000 and $2,455,000 for
the years ended December 31, 1995, 1994 and 1993, respectively.

     The Company is a guarantor of approximately $1,557,000 in credit facilities
available  to equity  investees  in France,  Canada and New York.  Approximately
$882,000 has been drawn on these  facilities as of December 31, 1995. The credit
facilities bear interest at rates ranging from 8.5% to 10.5%.

7. REDEEMABLE PREFERRED STOCK

     In November 1993, the Company  authorized 50,000 shares of preferred stock.
The  first  series,  Series A, was  authorized  at 5,000  shares  of  cumulative
preferred  stock  with a par value of $100 per  share.  In  December  1994,  the
Company  authorized an additional 15,000 shares of the Series A preferred stock.
The Company's profit sharing and 401(k) plan is the only holder of the preferred
stock.  The Series A cumulative  preferred  stock  dividend is $90 per annum per
share,  payable  quarterly when declared by the Board of Directors.  The Company
repurchases  preferred  stock  from the  profit  sharing  and  401(k)  plan when
participants  in the plan elect to  purchase  an  investment  option  other than
preferred stock, and when participants terminate employment with the Company and
leave the plan. The preferred stock is sold and repurchased at $1,000 per share,
the price established by an agreement between the Company and the profit sharing
and 401(k) plan.  The Company may redeem the  preferred  stock at any time after
January 1, 2003, at the option of the Board of  Directors,  at a price of $1,045
per share plus all accrued  and unpaid  dividends.  The stock has a  liquidation
preference over holders of common stock of $1,000 per share plus all accrued and
unpaid dividends.


8. COMMON STOCK SUBJECT TO REPURCHASE OBLIGATIONS

   
     Under the Company's shareholder agreements, the common stock of the Company
is both sold and  repurchased by the Company at a price  determined by a formula
based  primarily upon book value,  adjusted for certain items  determined by the
Board of Directors.  The adjustment  from book value in determining  the formula
price is primarily related to the restructuring  charges recorded by the Company
in 1993 (see Note 13).  These charges have been added back to book value and are
being  amortized  over 15 years for purposes of  determining  the formula price.
Other  adjustments are  insignificant.  At December 31, 1995, 1994 and 1993, the
formula prices were $60.01, $56.09 and $53.56 per share, respectively.

     The common stock of the Company is owned by the  employees  and the Company
is obligated to repurchase its common stock from the holders upon termination of
employment.  The total  repurchase  obligation  is recorded on the  consolidated
balance  sheets based on the formula price and number of  outstanding  shares at
each balance sheet date.  Changes in the  repurchase  obligation  resulting from
changes in the number of shares  outstanding  or formula price of the shares are
accounted  for by a charge  or credit to  equity  (accumulated  deficit)  in the
period  that such  change  occurs.  As shares are  repurchased,  the  repurchase

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


   
obligation is accordingly reduced by the number of shares repurchased multiplied
by the formula  price which was  utilized to  determine  the  obligation  in the
period the shares were  repurchased.  A substantial  number of employees finance
all or part of the stock  purchases  with recourse  notes issued to the Company.
The notes,  which are collateralized by the stock, bear interest at market rates
and are payable over five to twenty years.  The Company has an agreement  with a
bank whereby an employee may borrow funds from the bank to purchase  stock,  and
the  borrowings  are  guaranteed  by the Company.  These  guaranteed  borrowings
approximated $1,869,000 at December 31, 1995.
    

      At the Company's option,  amounts payable upon repurchase of common shares
are paid either by cash in a lump sum or over three to five years (see Note 6).

     The Company has  established a valuation  allowance for deferred income tax
assets primarily for losses recognized for book purposes,  which when realizable
for tax purposes will be capital  losses.  As the generation of capital gains to
offset these  capital  losses is not certain,  a valuation  allowance is needed.
Based on the  Company's  history of taxable  income and profit  projections  for
1996,  management  believes it is more  likely  than not that the  Company  will
realize the benefit of the remaining net deferred tax assets.
    

     No domestic income taxes have been provided on approximately $1,595,000 and
$719,000 of unremitted earnings of foreign subsidiaries at December 31, 1995 and
1994,  respectively,  since  such  earnings  have  been  or are  intended  to be
permanently  reinvested.  It is not practicable to determine the deferred income
tax liability for these earnings.

     Income taxes paid were approximately $1,177,000,  $1,708,000 and $2,473,000
for the years ended December 31, 1995, 1994 and 1993, respectively.

10. EMPLOYEE BENEFIT PLANS

     During 1995 the Company combined its profit sharing and 401(k) plans into a
single plan. The Company contribution to the 401(k) portion of the plan has been
increased  from $0.33 to $0.50 for every dollar of employee  contributions.  The
Company  will match up to 4% of the  employee's  base  salary.  The Company also
contributes,  at the  direction of the Board of  Directors,  a minimum of 20% of
pre-tax consolidated income. Plan expense for 1995 was $2,213,000.

     The  Company  previously  maintained  a profit  sharing  plan for  salaried
employees who had completed six months of service  without  incurring a one-year
interruption  in  employment.  The  plan  provided  for  contributions,  at  the
discretion  of  the  Board  of  Directors,  at  a  minimum  of  20%  of  pre-tax
consolidated  income.  Contributions  paid  to  the  profit  sharing  plan  were
allocated among participants on the basis of eligible  compensation paid. Profit
sharing expense was $1,250,000 and $1,100,000 in 1994 and 1993, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


     The Company  previously also maintained a salary  reduction  profit sharing
plan under  Section  401(k) of the  Internal  Revenue  Code.  This plan  allowed
employees  to defer  compensation  through  contributions  to the  plan.  At the
discretion of the Board of Directors,  the Company  contributed  $0.33 for every
dollar of employee  contributions  up to a maximum of 2% of the employee's  base
salary. Plan expense was $610,000 and $565,000 in 1994 and 1993, respectively.

11. LEASE COMMITMENTS

     The  Company has  operating  leases for its office  facilities  and certain
equipment, which require minimum monthly rental payments and a pro-rata share of
common  operating  expenses for office  rentals.  Operating lease expense was as
follows:

                                                Year Ended December 31,

     Future  minimum lease payments for all  noncancelable  office and equipment
leases in effect at December 31, 1995 are as follows:

12. COMMITMENTS AND CONTINGENCIES

     Ketchum is the subject  of, or party to, a number of  lawsuits  and claims.
Included in other accrued  expenses is $4,961,434  and $200,000 for  outstanding
and settled litigation matters at December 31, 1995 and 1994,  respectively (see
Note 14). In the opinion of management,  any ultimate  liabilities  arising from
these  contingencies,  to the extent not provided  for, will not have a material
effect on the Company's financial position or results of operations.

     Under the terms of prior  agency  acquisition  and  investment  agreements,
additional  payments  may be  required,  contingent  upon  future  revenues  and
earnings of these agencies. Any additional payments are recorded as increases in
the  excess of cost over the fair value of net  assets  acquired  at the time in
which  such  payments  are  determined.   Additional   payments  on  prior  year
acquisitions  made  in 1995  and  1994  approximated  $342,000  and  $1,708,000,
respectively.

     In the event the Company is sold, the Company is obligated, under the terms
of agreements with certain parties who have sold shares of the Company's  common
stock to the Company  within the past five years,  to pay such parties an amount
based upon the difference  between the Company's  formula price per share at the
month end preceding the sale and the price  received for shares in a sale of the
Company.  The Company  estimates that the potential  settlement with parties who
may have claims  because they sold shares  within the previous  five years would
approximate $5 million in the event the merger with Omnicom is consummated  (see
Note 15).
      
     In  1995,  management  made a  decision  to  reorganize  its  media  buying
operations. A detailed plan has yet to be developed; however management believes
that any expenses to be incurred in connection with the reorganization  will not
have a material  effect on the Company's  financial  condition or the results of
its operations.

13. RESTRUCTURING CHARGES

   
     In 1993, the Company  developed a formal plan to  significantly  reduce the
Company's cost structure. The restructuring plan involved the sale or close-down
of four operations.  A provision for the restructuring charges of $8,778,572 was
recorded in 1993 and  consists  primarily  of the  write-offs  of  approximately
$6,000,000  of the  excess of cost over the fair  value of net  assets  acquired
related to certain business  acquisitions and approximately  $1,900,000 in lease
abandonment  charges in connection  with vacating the leased space of one of the
closed operations. At December 31, 1995, approximately $821,000 remains in other
liabilities related to a lease abandonment which is expected to be paid out over
a two year period.
    

14. OTHER EXPENSE

      Other expense is comprised of the following:

</TABLE>

   
      Included  in  litigation  matters in 1995 is a $4.0  million  charge for a
judgment  against Ketchum related to a prior  acquisition in the United Kingdom.
This case was a  contract  dispute  between  the  majority  owners  and  Ketchum
relative to the  exercise  of a put option  requiring  Ketchum to  purchase  the
majority stake as well as a dispute relating to certain  dividends  declared and
paid prior to the put without Ketchum's  consent.  Judgment was rendered against
Ketchum on  February  21, 1996 for  approximately  $3.5  million.  Additionally,
Ketchum was subsequently  ordered to pay $0.5 million for a cost contribution to
the plaintiffs' legal costs. The remaining $1.0 million of the litigation charge
primarily  relates  to two cases  where  judgments  have been  rendered  against
Ketchum  and loss is  considered  probable,  although  appeals are  pending.  An
additional  reserve of $0.5  million was  recorded in 1995,  in addition to $0.2
million  previously  accrued,  for the first case, a case in which Ketchum was a
minority  shareholder of a Parisian  advertising  agency which went bankrupt and
where  Ketchum may be required to contribute to the full amount of the shortfall
in net assets.  The potential range of loss in this case is between $0.7 million
and $1.2  million.  A charge of $0.3  million was  recorded  for the second case
which is related to Ketchum  holding  over in certain New York office  space for
one month.  These  amounts are  included in accrued  expenses  (see Note 12). In
management's  opinion Ketchum's exposure for unrecorded losses of all litigation
matters is insignificant.

      The write-off of notes  receivable from equity investees and the equity in
net loss of  equity  investees  arises  primarily  from an  investee  which  has
incurred  significant  losses since its  formation  and which  continues to have
significant cash short falls.
    

15. SUBSEQUENT EVENT
 
     During  1996  Ketchum  has  entered  into  negotiations  for a merger  with
Omnicom.  The terms of the merger agreement being discussed  provide for Omnicom
to  acquire  all of the  outstanding  common and  preferred  stock of Ketchum in
exchange for common  shares of Omnicom as based upon the market value of Omnicom
common  shares  and the  "Common  Stock  Conversion  Price"  for the  common and
preferred  stock of Ketchum at the merger  date,  as defined in the draft merger
agreement.

equitable relief),  1904 (relating to de facto transaction  doctrine  abolished)
and 2512 (relating to dissenters rights procedure). (Last amended by Act 198, L.
'90, eff. 12-19-90.)

     1572  DEFINITIONS.  The  following  words  and  phrases  when  used in this
subchapter  shall have the  meanings  given to them in this  section  unless the
context clearly indicates otherwise:

     "Corporation."  The  issuer of the  shares  held or owned by the  dissenter
before the corporate action or the successor by merger, consolidation,  division
conversion or otherwise of that issuer.  A plan of division may designate  which
of the resulting  corporations is the successor  corporation for the purposes of
this  subchapter.  The  successor  corporation  in a  division  shall  have sole
responsibility  for  payments to  dissenters  and other  liabilities  under this
subchapter except as otherwise provided in the plan of division.

     "Dissenter." A shareholder or beneficial  owner who is entitled to and does
assert  dissenters  rights under this subchapter and who has performed every act
required up to the time involved for the assertion of those rights.

     "Fair value." The fair value of shares  immediately before the effectuation
of the corporate  action to which the dissenter  objects taking into account all
relevant factors, but excluding any appreciation or depreciation in anticipation
of the corporate action.

     "Interest."  Interest from the effective date of the corporate action until
the  date of  payment  at  such  rate as is fair  and  equitable  under  all the
circumstances,  taking into account all relevant  factors  including the average
rate  currently  paid by the  corporation  on its  principal  bank loans.  (Last
amended by Act 198, L. '90, eff. 12-19-90.)

     1573 RECORD AND  BENEFICIAL  HOLDERS  AND  OWNERS.--(a)  Record  holders of
shares.--A  record  holder  of  shares  of a  business  corporation  may  assert
dissenters rights as to fewer than all of the shares registered in his name only
if he  dissents  with  respect  to all the  shares  of the same  class or series
beneficially  owned by any one person and  discloses the name and address of the
person or persons on whose behalf he dissents.  In that event,  his rights shall
be determined as if the shares as to which he has dissented and his other shares
were registered in the names of different shareholders.

     (b)  Beneficial  owners  of  shares.--A  beneficial  owner of  shares  of a
business  corporation who is not the record holder may assert  dissenters rights
with  respect to shares held on his behalf and shall be treated as a  dissenting
shareholder  under the terms of this subchapter if he submits to the corporation
not later than the time of the assertion of dissenters  rights a written consent

                                      A-2
<PAGE>

of the record  holder.  A beneficial  owner may not dissent with respect to some
but less than all shares of the same class or series owned by the owner, whether
or not the shares so owned by him are  registered in his name.  (Last amended by
Act 169, L. '92, eff. 2-16-93.)

     1574 NOTICE OF INTENTION TO DISSENT.--If  the proposed  corporate action is
submitted to a vote at a meeting of shareholders of a business corporation,  any
person who wishes to dissent and obtain  payment of the fair value of his shares
must file with the corporation, prior to the vote, a written notice of intention
to demand that he be paid the fair value for his shares if the  proposed  action
is effectuated,  must effect no change in the beneficial ownership of his shares
from the date of such  filing  continuously  through the  effective  date of the
proposed  action and must  refrain  from  voting his shares in  approval of such
action.  A  dissenter  who fails in any  respect  shall not acquire any right to
payment of the fair value of his shares under this  subchapter.  Neither a proxy
nor a vote against the proposed  corporate  action shall  constitute the written
notice required by this section.

     1575  NOTICE  TO DEMAND  PAYMENT.  --(a)  General  rule.--If  the  proposed
corporate  action is approved by the required vote at a meeting of  shareholders
of a business  corporation,  the corporation  shall mail a further notice to all
dissenters  who gave due notice of intention to demand payment of the fair value
of their shares and who refrained  from voting in favor of the proposed  action.
If the proposed  corporate action is to be taken without a vote of shareholders,
the corporation  shall send to all  shareholders who are entitled to dissent and
demand payment of the fair value of their shares a notice of the adoption of the
plan or other corporate action. In either case, the notice shall:

     (1) State where and when a demand for payment must be sent and certificates
for certificated shares must be deposited in order to obtain payment.

     (2) Inform  holders of  uncertificated  shares to what  extent  transfer of
shares will be restricted from the time that demand for payment is received.

     (3)  Supply a form for  demanding  payment  that  includes  a  request  for
certification  of the date on which  the  shareholder,  or the  person  on whose
behalf the shareholder dissents, acquired beneficial ownership of the shares.

     (4) Be accompanied by a copy of this subchapter.

     (5) Time for  receipt of demand for  payment.--The  time set for receipt of
the demand and  deposit of  certificated  shares  shall be not less than 30 days
from the mailing of the notice.

      1576 FAILURE TO COMPLY WITH NOTICE TO DEMAND PAYMENT, ETC. --(a) Effect of
failure  of  shareholder  to  act.--A  shareholder  who fails to  timely  demand
payment,  or fails  (in the  case of  certificated  shares)  to  timely  deposit
certificates,  as required by a notice  pursuant to section  1575  (relating  to
notice to demand  payment)  shall not have any right  under this  subchapter  to
receive payment of the fair value of his shares.

     (b)   Restriction  on   uncertificated   shares.--If  the  shares  are  not
represented  by  certificates,  the  business  corporation  may  restrict  their
transfer  from the time of receipt of demand for payment until  effectuation  of
the proposed  corporate action or the release of restrictions under the terms of
section 1577(B) (relating to failure to effectuate corporate action).

     (c) Rights retained by  shareholder.--The  dissenter shall retain all other
rights of a shareholder  until those rights are modified by  effectuation of the
proposed corporate action. (Last amended by Act 198, L. '90, eff. 12-19-90.)

     1577  RELEASE OF  RESTRICTIONS  OR PAYMENT  FOR  SHARES.  --(a)  Failure to
effectuate  corporate  action.--Within  60 days after the date set for demanding
payment  and  depositing  certificates,  if the  business  corporation  has  not
effectuated the proposed corporate action, it shall return any certificates that
have  been  deposited  and  release  uncertificated  shares  from  any  transfer
restrictions imposed by reason of the demand for payment.

                                      A-3
<PAGE>

     (b) Renewal of notice to demand  payment.--When  uncertificated shares have
been released from transfer  restrictions and deposited  certificates  have been
returned,  the corporation may at any later time send a new notice conforming to
the  requirements of section 1575 (relating to notice to demand  payment),  with
like effect.

     (c) Payment of fair value of  shares.--Promptly  after  effectuation of the
proposed  corporate  action, or upon timely receipt of demand for payment if the
corporate  action has already been  effectuated,  the  corporation  shall either
remit to dissenters who have made demand and (if their shares are  certificated)
have deposited their  certificates the amount that the corporation  estimates to
be the fair value of the shares, or give written notice that no remittance under
this section will be made. The remittance or notice shall be accompanied by:

     (1) The closing  balance sheet and statement of income of the issuer of the
shares held or owned by the  dissenter for a fiscal year ending not more than 16
months  before  the date of  remittance  or  notice  together  with  the  latest
available interim financial statements.

     (2) A  statement  of the  corporation's  estimate  of the fair value of the
shares.

     (3)  A  notice  of  the  right  of  the  dissenter  to  demand  payment  or
supplemental  payment,  as the  case  may  be,  accompanied  by a copy  of  this
subchapter.

     (d) Failure to make  payment.--If the corporation does not remit the amount
of its estimate of the fair value of the shares as provided by  subsection  (c),
it  shall  return  any  certificates   that  have  been  deposited  and  release
uncertificated  shares from any transfer  restrictions  imposed by reason of the
demand for payment.  The corporation may make a notation on any such certificate
or on the records of the corporation relating to any such uncertificated  shares
that such demand has been made.  If shares with  respect to which  notation  has
been so made shall be transferred,  each new certificate  issued therefor or the
records relating to any transferred  uncertificated  shares shall bear a similar
notation,  together with the name of the original  dissenting holder or owner of
such shares.  A transferee of such shares shall not acquire by such transfer any
rights in the  corporation  other than those that the  original  dissenters  had
after making  demand for payment of their fair value.  (Last amended by Act 198,
L. '90, eff. 12-19-90.)

     1578 ESTIMATE BY DISSENTER OF FAIR VALUE OF SHARES. --(a) General rule.--If
the business  corporation  gives notice of its estimate of the fair value of the
shares,  without remitting such amount, or remits payment of its estimate of the
fair value of a dissenter's  shares as permitted by section l577(c) (relating to
payment of fair  value of shares)  and the  dissenter  believes  that the amount
stated or remitted is less than the fair value of his shares, he may send to the
corporation  his own  estimate of the fair value of the  shares,  which shall be
deemed a demand for payment of the amount or the deficiency.

     (b) Effect of failure to file  estimate.--Where the dissenter does not file
his own estimate  under  subsection  (a) within 30 days after the mailing by the
corporation of its remittance or notice,  the dissenter  shall be entitled to no
more than the amount stated in the notice or remitted to him by the corporation.
(Last amended by Act 198, L, '90, eff. 12-19-90.)

     1579 VALUATION  PROCEEDINGS  GENERALLY.--(a)  General rule.--Within 60 days
after the latest of:

     (1) Effectuation of the proposed corporate action;

     (2) Timely  receipt of any demands for payment under section 1575 (relating
to notice to demand payment); or

     (3) Timely  receipt of any estimates  pursuant to section 1578 (relating to
estimate by dissenter of fair value of shares);

     If any demands for payment remain unsettled,  the business  corporation may
file in court an application  for relief  requesting  that the fair value of the
shares be determined by the court.

     (b) Mandatory joinder of  dissenters.--All  dissenters,  wherever residing,
whose demands have not been settled  shall be made parties to the  proceeding as
in an action against their shares. A copy of the application  shall be served on
each such dissenter. If a dissenter is a nonresident,  the copy may be served on
him in the manner  provided or  prescribed  by or pursuant to 42 Pa.C.S.  Ch. 53
(relating to bases of jurisdiction and interstate and international procedure).

                                      A-4
<PAGE>

      (c)  Jurisdiction  of the  court.--The  jurisdiction of the court shall be
plenary and  exclusive.  The court may appoint an appraiser to receive  evidence
and recommend a decision on the issue of fair value.  The  appraiser  shall have
such power and authority as may be specified in the order of  appointment  or in
any amendment thereof.

      (d)  Measure of  recovery.--Each  dissenter  who is made a party  shall be
entitled to recover the amount by which the fair value of his shares is found to
exceed the amount, if any, previously remitted, plus interest.

      (e)  Effect  of  corporation's   failure  to  file   application.--If  the
corporation  fails to file an  application  as provided in  subsection  (a), any
dissenter  who made a demand and who has not already  settled his claim  against
the  corporation  may do so in the name of the corporation at any time within 30
days after the expiration of the 60-day period.  If a dissenter does not file an
application  within  the  30-day  period,  each  dissenter  entitled  to file an
application  shall, be paid the corporation's  estimate of the fair value of the
shares and no more, and may bring an action to recover any amount not previously
remitted.

     1580 COSTS AND EXPENSES OF VALUATION  PROCEEDINGS.--(a)  General rule.--The
costs and expenses of any  proceeding  under section 1579 (relating to valuation
proceedings  generally),  including the reasonable  compensation and expenses of
the  appraiser  appointed  by the court,  shall be  determined  by the court and
assessed against the business  corporation except that any part of the costs and
expenses may be apportioned and assessed as the court deems appropriate  against
all or some of the  dissenters  who are  parties and whose  action in  demanding
supplemental  payment under  section 1578  (relating to estimate by dissenter of
fair value of  shares)  the court  finds to be  dilatory,  obdurate,  arbitrary,
vexatious or in bad faith.

     (b)  Assessment  of counsel  fees and expert  fees where lack of good faith
appears.--  Fees and  expenses  of  counsel  and of experts  for the  respective
parties may be assessed as the court deems  appropriate  against the corporation
and in  favor of any or all  dissenters  if the  corporation  failed  to  comply
substantially  with the  requirements  of this  subchapter  and may be  assessed
against either the  corporation or a dissenter,  in favor of any other party, if
the court finds that the party  against  whom the fees and expenses are assessed
acted in bad faith or in a dilatory,  obdurate, arbitrary or vexatious manner in
respect to the rights provided by this subchapter.

     (c) Award of fees for  benefits  to other  dissenters.--If  the court finds
that the services of counsel for any dissenter  were of  substantial  benefit to
other  dissenters  similarly  situated  and should not be  assessed  against the
corporation, it may award to those counsel reasonable fees to be paid out of the
amounts awarded to the dissenters who were benefited.

                                     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  schedule   included in Omnicom's  Annual
Report on Form 10-K for the year ended  December  31, 1995  incorporated  in the
Prospectus/Information Statement included in this Registration Statement.

Item 22.   Undertakings.

     (a) The undersigned  Registrant  hereby undertakes that, for the purpose of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual  report  pursuant  to Section  13 or  Section  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 that purports to meet
the  requirements  of  Section  10(a)(3)  of the  Securities  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/Information
Statement 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.
