                       OMNICOM GROUP INC. AND SUBSIDIARIES
         NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1.    We have prepared the consolidated  condensed interim financial  statements
      included   herein  without  audit  pursuant  to  Securities  and  Exchange
      Commission rules.  Certain information and footnote  disclosures  normally
      included in financial  statements  prepared in accordance  with  generally
      accepted accounting principles,  or "GAAP", have been condensed or omitted
      pursuant to these  rules.  All dollar  amounts in these  footnotes  are in
      thousands   (unless   otherwise   specifically   indicated   by  the  word
      "millions").

2.    The accompanying financial statements reflect all adjustments,  consisting
      of normally  recurring  accruals,  which in the opinion of management  are
      necessary  for a fair  presentation,  in  all  material  respects,  of the
      information contained therein. Certain reclassifications have been made to
      the September  30, 2001 and December 31, 2001 reported  amounts to conform
      them to the  September  30,  2002  presentation.  These  reclassifications
      include  changing the income  statement line item from "Salary and related
      costs"  to a  new  category  entitled  "Salary  and  service  costs",  and
      reallocating  certain  items  previously  shown  in  "Office  and  general
      expenses" to this new category.  We have regrouped  certain direct service
      costs such as freelance labor, travel, entertainment, reproduction, client
      service costs and other  expenses from "Office and general  expenses" into
      "Salary and service costs" in order to better  segregate the expense items
      between those that are more closely  related to directly  serving  clients
      versus those  expenses,  such as facilities,  overhead,  depreciation  and
      other administrative expenses, which in nature are not directly related to
      servicing clients. These statements should be read in conjunction with the
      consolidated financial statements and related notes included in our annual
      report on Form 10-K for the year ended  December 31, 2001,  which we refer
      to later in this report as our "2001 10-K".

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

4.    Basic  earnings  per share is based upon the  weighted  average  number of
      common shares outstanding during the period. Diluted earnings per share is
      based on the above,  plus,  if dilutive,  common share  equivalents  which
      include  outstanding  options and  restricted  shares.  No  adjustments to
      diluted  earnings  per share  were  made for our Zero  Coupon  Zero  Yield
      Convertible  Notes  due 2032 or our  Liquid  Yield  Option  Notes due 2031
      because the  conversion  criteria  applicable to each series of notes have
      not been met. For purposes of computing diluted earnings per share for the
      three months ended  September 30, 2002,  786,000 common share  equivalents
      were assumed to be outstanding for the current period and 1,746,000 common
      share equivalents were assumed to have been outstanding for the comparable
      period last year. For the purposes of computing diluted earnings per share
      for the nine months  ended  September  30,  2002,  1,816,000  common share
      equivalents  were  assumed  to  be  outstanding  for  current  period  and
      2,334,000  common share  equivalents were assumed to have been outstanding
      for the comparable  period last year. In December 2001, our $230.0 million
      aggregate principal amount of 2 1/4% convertible  subordinated  debentures
      were called for  redemption  and  subsequently  converted  by holders into
      4,612,000  shares of common stock.  The additional  shares are included in
      shares

      outstanding  at September 30, 2002 and were assumed to have been converted
      for the September 30, 2001 computation.

            The  assumed  increase  in  net  income  related  to  the  after-tax
      compensation expense related to dividends on restricted shares used in the
      computation  was $252.0 for the three months ended  September 30, 2002 and
      the assumed increase in net income related to the after-tax  interest cost
      of the  convertible  debentures  and the  after-tax  compensation  expense
      related to  dividends on  restricted  shares used in the  computation  was
      $2,499.0  for the three  months  ended  September  30,  2001.  The assumed
      increase  in net income  related  to the  after-tax  compensation  expense
      related to  dividends on  restricted  shares used in the  computation  was
      $757.0 for the nine months  ended  September  30, 2002 and the increase in
      net income related to the after-tax interest of the convertible debentures
      and the after-tax  compensation expense related to dividends on restricted
      shares used in the  computation  was  $7,462.0  for the nine months  ended
      September 30, 2001.

6.    The Financial  Accounting  Standards  Board issued  Statement of Financial
      Accounting  Standards No. 142, Goodwill and Other Intangible Assets ("SFAS
      142"),  in June 2001 and Statement of Financial  Accounting  Standards No.
      144, Accounting for the Impairment or Disposal of Long-Lived Assets ("SFAS
      144"), in August 2001.

            Effective  January 1, 2002, the Company adopted SFAS 142,  "Goodwill
      and Other Intangible  Assets",  and no longer amortizes goodwill and other
      intangibles  with indefinite  lives.  These assets are subject to periodic
      testing for impairments at least annually. Substantially all of our assets
      subject to the  impairment  test  consisted of goodwill.  We completed the
      impairment  test  required  by SFAS 142 in the  second  quarter of 2002 by
      comparing the fair value of our reporting units to their carrying  values.
      We also  reassessed  the  useful  lives  of  other  intangibles  that  are
      amortized. As of January 1, 2002, we concluded that the fair values of the
      reporting units exceeded the carrying values of the reporting  units,  and
      therefore upon adoption no impairment charge was recognized in our results
      of  operations  and  financial  position  and no changes  were made to the
      useful lives of our other intangibles.

            The following  summary table presents the impact of the  elimination
      of  goodwill  amortization  as  required  by the  adoption  of SFAS 142 on
      operating  income,  profit  before  tax  ("PBT"),  equity  in  affiliates,
      minority interest and earnings per share ("EPS") had the statement been in
      effect at the beginning of 2001.

            SFAS 144 establishes a single accounting model for the impairment or
      disposal of long-lived assets, including discontinued operations. SFAS 144
      superseded Statement of Financial Accounting Standards No. 121, Accounting
      for the Impairment of Long-Lived  Assets and for  Long-Lived  Assets to Be
      Disposed   Of,  and  APB  Opinion  No.  30,   Reporting   the  Results  of
      Operations-Reporting  the  Effects of Disposal of a Segment of a Business,
      and   Extraordinary,   Unusual  and  Infrequently   Occurring  Events  and
      Transactions.  We adopted SFAS 144 effective January 1, 2002. The adoption
      had no  material  impact on our  consolidated  results of  operations  and
      financial position.

   NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued)

            In July 2000,  the Emerging  Issues Task Force of the FASB  ("EITF")
      released Issue 99-19, Reporting Revenue Gross as a Principal versus Net as
      an Agent. This Issue summarized the EITF's views on when revenue should be
      recorded at the gross amount billed because it has earned revenue from the
      sale of goods or  services,  or the net  amount  retained  because  it has
      earned  a fee or  commission.  Additionally,  in  January  2002,  the EITF
      released Issue 01-14, Income Statement  Characterization of Reimbursements
      Received for "Out-of-Pocket"  Expenses Incurred. This Issue summarized the
      EITF's views on when  out-of-pocket  expenses should be  characterized  as
      revenue. The Company's revenue recognition policies are in compliance with
      EITF 99-19 and EITF 01-14. In  substantially  all of our businesses we act
      as an  agent  and  record  revenue  for  reimbursements  when  the  fee or
      commission is earned.

7.    Our wholly and partially owned businesses operate within the marketing and
      corporate  communications  services  operating  segment.  These businesses
      provide a variety  of  communications  services  to  clients  on a global,
      pan-regional  and national basis. On a regional basis, we believe that the
      businesses  have  similar  cost  structures  and are  subject  to the same
      general economic and competitive risk.

            Our revenue and long-lived assets by geographic area as of September
      30, 2002 and 2001, is summarized in the following table.

8.    At September 30, 2002, we had a $1,600.0 million 364-day  revolving credit
      facility  with a  consortium  of banks for  which  Citibank  N.A.  acts as
      administrative  agent and Salomon Smith Barney Inc. acts as lead arranger.
      The  consortium   consists  of  23  banks.   Other   significant   lending
      institutions  include The Bank of Nova Scotia,  JPMorgan Chase Bank, Fleet
      National Bank,  HSBC Bank USA and San Paolo IMI S.p.A.  In April 2002, the
      facility was extended on  substantially  the same terms as had  previously
      been in effect,  including  a  provision  which  allows us to convert  all
      amounts  outstanding at expiration on April 25, 2003, into a one-year term
      loan. The facility, which can be drawn down at any time, also supports the
      issuance of up to $1,500.0 million of commercial paper.

   NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued)

      At September 30, 2002,  we had issued and  outstanding  $200.0  million of
      commercial paper which is classified as long-term debt.

            We also have a $500.0  million  5-year  revolving  credit  facility,
      which expires on June 30, 2003, with a similar  consortium of 13 banks for
      which ABN AMRO Bank acts as agent. Other significant lending  institutions
      include Bank of America,  HSBC, JPMorgan Chase and Wachovia. We had $374.0
      million outstanding under this facility at September 30, 2002.

            We also had short-term  bank loans of $95.0 million at September 30,
      2002,   primarily  comprised  of  unsecured  overdrafts  of  international
      subsidiaries which are classified as bank loans.

            We had a total of $1,750.0  million  aggregate  principal  amount of
      Liquid Yield Option and Zero Coupon Zero Yield 30-year  notes  outstanding
      as further described in Note 9.

            At September 30, 2002,  the unused  portion of our committed  credit
      facilities was $1,526.0 million.

9.    In March 2002, we issued $900.0 million aggregate principal amount of Zero
      Coupon  Zero  Yield  Convertible  Notes  due 2032.  The  notes are  senior
      unsecured  securities that are convertible into 8.2 million common shares,
      implying a conversion price of $110.01 per common share, subject to normal
      anti-dilution  adjustments.  These notes are  convertible at the specified
      ratio only upon the occurrence of certain events,  including if our common
      shares trade above certain levels, if we effect extraordinary transactions
      or if our  long-term  debt ratings are  downgraded  at least three notches
      from their current level to Baa3 or lower by Moody's  Investors  Services,
      Inc. or BBB or lower by Standard & Poor's Ratings  Services.  These events
      would  not,  however,  result  in an  adjustment  of the  number of shares
      issuable upon conversion. Holders of these notes have the right to put the
      notes back to us for, at our election,  cash,  stock or a  combination  of
      both in August of each year beginning in August 2003 and we have the right
      to redeem the notes for cash  beginning in 2007.  There are no events that
      accelerate the noteholders'  put rights.  Beginning in August 2007, if the
      market price of our common shares exceeds  certain  thresholds,  we may be
      required to pay contingent  cash interest on the notes equal to the amount
      of dividends  that would be paid on the common shares into which the notes
      are contingently convertible.

            The net proceeds of the issuance of these notes were $905.0 million.
      We used a portion  of these  proceeds  to  repurchase  3.0  million of our
      common  shares.  We applied the balance of the net  proceeds to reduce our
      short-term  borrowings  pending use for working  capital and other general
      corporate purposes.

            These  notes  are  substantially   similar  to  the  $850.0  million
      aggregate  principal  amount of Liquid Yield Option Notes due 2031 that we
      issued in February  2001.  These

      if we effect  extraordinary  transactions or if our long-term debt ratings
      are  downgraded at least three notches from their current level to Baa3 or
      lower by Moody's  Investors  Services,  Inc. or BBB or lower by Standard &
      Poor's Ratings  Services.  These events would not,  however,  result in an
      adjustment  of  the  number  of  shares  issuable  upon  conversion.   The
      noteholder  put dates for the 2031  notes  are in  February  2003 and each
      February thereafter.

10.   Our operating  companies  completed  acquisitions  and made investments in
      other agencies over the last twelve-month  period.  The revenue from these
      acquired  businesses  impacts  comparability  to prior period revenues for
      twelve  months  following  the date of  acquisition.  The  revenue  of the
      acquired  businesses is calculated by  aggregating  the  applicable  prior
      period revenue of the acquired  businesses.  Netted against this number is
      the revenue of any business  included in the prior period revenue that was
      disposed of subsequent to the prior period.  The aggregate  revenue of the
      acquired  businesses  was $76.2  million for the third  quarter and $309.8
      million  for the first nine  months of the year.  These  acquisitions  and
      investments  are  consistent  with  our  strategy  of  pursuing   business
      transactions  that are  expected  to expand  relationships  with  existing
      clients,  expand the geographic  reach of our networks or increase service
      offerings to meet client requirements.

            During  the  first  nine   months  of  this  year,   the   aggregate
      consideration for acquisitions,  including assumed liabilities, was $385.2
      million.  As is typical in our business,  certain of the acquisitions were
      structured as "earn-outs," or transactions in which the ultimate  purchase
      price payable is  determined in part by reference to the future  financial
      performance  of the  acquired  business.  Included in the above  amount is
      $181.9 million related to transactions closed in prior periods.

11.   On June 13, 2002, a lawsuit was filed against us and certain of our senior
      executives  in the federal  court in the Southern  District of New York on
      behalf of a purported  class of purchasers of our common shares during the
      period April 25, 2000 to June 11, 2002. The complaint alleges, among other
      things,  that our press  releases and SEC filings during the alleged class
      period contained materially false and misleading  statements or omitted to
      state material  information.  The complaint seeks an unspecified amount of
      money  damages  plus  attorneys'  fees  and  other  costs.   Eleven  other
      complaints were subsequently  filed in the same court, each making similar
      allegations and referencing the same class period.

            In  addition  to the  proceedings  described  above,  a  shareholder
      derivative  action was filed on June 28, 2002 by a plaintiff  stockholder,
      purportedly on our behalf alleging breaches of fiduciary duty,  disclosure
      failures,  abuse of control and gross mismanagement in connection with the
      formation of Seneca  Investments LLC, including as a result of open-market
      sales  of our  common  shares  by our  chairman  and two  former  employee
      directors.  The complaint seeks the imposition of a constructive  trust on
      profits  received  in the  stock  sales,  an  unspecified  amount of money
      damages  and  attorneys'  fees and  other  costs  and are  expected  to be
      consolidated and a lead plaintiff  appointed in accordance with


                                       11

      applicable  procedures.  A motion has been filed to dismiss  this  action.
      Subsequently,  the parties agreed to stay further proceedings in this case
      pending additional developments in the class action cases described above.

            We are also  subject to numerous  lawsuits  and other  claims in the
      ordinary course of business.

            Management presently expects that the matters referred to above will
      not individually or in the aggregate have a material adverse effect on our
      financial position or results of operations.  However,  the outcome of any
      of these  matters is  inherently  uncertain  and may be affected by future
      events.  Accordingly,  there can be no assurance as to the ultimate effect
      of these matters.

12.   On  November  14,  2002,  we  entered  into a new  3-year  $800.0  million
      revolving  credit  facility  which  matures  November  14,  2005 and a new
      $1,000.0  million  364-day  revolving  credit  facility  which  matures on
      November 13, 2003. These facilities  replaced the existing facilities that
      are described in Note 8 which were due to mature in the second  quarter of
      2003. Both facilities provide for credit support of the Company's existing
      $1,500.0  million  commercial  paper  program.  The  new  facilities  have
      substantially the same terms as had previously been in effect. The 364-day
      facility  continues  to include a  provision  which  allows the Company to
      convert all amounts  outstanding  at  expiration  of the  facility  into a
      one-year term loan. The  consortium of banks  providing the new facilities
      had previously participated in the facilities that were replaced.

Results of Operations

      As discussed and presented in footnote 6 of the notes to our third quarter
financial  statements,  beginning in 2002 and as required by SFAS 142, we are no
longer  amortizing  goodwill and other  intangible  assets that have  indefinite
lives due to a change in generally accepted accounting  principles.  To make the
discussion  of periods  comparable,  2001 income  statement  information  in the
discussion that follows has been adjusted to eliminate goodwill amortization. In
addition, certain reclassifications have been made to the September 30, 2001 and
December 31, 2001  reported  amounts to conform them to the  September  30, 2002
presentation, including changing the income statement line item from "Salary and
related  costs" to a new  category  entitled  "Salary  and service  costs",  and
reallocating  certain items previously shown in "Office and general expenses" to
this new category as  described in footnote 2 of the notes to our third  quarter
financial statements.

Third Quarter 2002 Compared to Third Quarter 2001

      Revenue:  Our consolidated  worldwide revenue in the third quarter of 2002
increased 12.6% to $1,768.5  million from $1,571.0  million in the third quarter
of 2001.  The effect of  acquisitions,  net of  disposals,  increased  worldwide
revenue by $76.2 million, or 4.9%.  Internal/organic  growth increased worldwide
revenue by $74.9  million,  or 4.7%,  and  foreign  exchange  impacts  increased
worldwide  revenue by $46.4  million,  or 3.0%.  The components of total revenue
growth by category are summarized below ($ in millions):



                                        Total                Domestic             International

Components of Revenue Changes:
Foreign exchange impact ......       46.4        3.0%         --         --        46.4         6.3%
Acquisitions .................       76.2        4.9%       56.8        6.8%       19.4         2.6%
Organic ......................       74.9        4.7%      103.6       12.5%      (28.7)       (3.9)%

                                 ========   ========    ========   ========    ========    ========


The components and percentages are calculated as follows:

      o     The  foreign  exchange  impact  component  shown  in  the  table  is
            calculated by first  converting the current  period's local currency
            revenue using the average  exchange rates from the equivalent  prior
            period  to  arrive  at a  constant  currency  revenue  (in this case
            $1,722.1  million for the Total  column in the  table).  The foreign
            exchange  impact equals the  difference  between the current  period
            revenue in U.S.  dollars and the current  period revenue in constant
            currency (in this case $1,768.5  million less  $1,722.1  million for
            the Total column in this table).

      o     The  acquisition  component  shown  in the  table is  calculated  by
            aggregating  the  applicable  prior  period  revenue of the acquired
            businesses.  Netted  against  this  number  is  the


                                       13


ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS (Continued)

            revenue  of any  business  included  in the  prior  period  reported
            revenue that was disposed of subsequent to the prior period.

      o     The  organic   component   shown  in  the  table  is  calculated  by
            subtracting  both  the  foreign  exchange  and  acquisition  revenue
            components from total revenue growth.

      o     The  percentage  change  shown  in the  table of each  component  is
            calculated by dividing the individual  component amount by the prior
            period revenue base of that component (in this case $1,571.0 million
            for the Total column in the table).

      The present  state of the global  economy  continues to create a difficult
business  climate.  While U.S.  media  companies  have  experienced  some recent
improvement in advertising sales, this has not resulted in a similar improvement
for our businesses.  Although  management  believes that the recent improvements
reported by U.S. media  companies are a positive sign,  management also believes
that the overall demand for advertising and marketing  services in the near term
will continue to be challenging.  However,  several long-term trends continue to
positively affect our business, including our clients increasingly expanding the
focus of their brand  strategies  from  national  markets to the global  market.
Additionally,  in an effort to gain greater  efficiency and  effectiveness  from
their marketing dollars, clients are increasingly requiring greater coordination
of their  traditional  advertising  and marketing  activities and  concentrating
these  activities  with a smaller  number  of  service  providers.  All of these
factors affect the geographic and service mix of our business  period to period.
Further, any comparison of current period results to the prior year,  especially
when comparing the third quarter of 2002 to the third quarter of 2001,  needs to
be made in the context of the events of September  11,  which had a  significant
adverse  impact on our business in the third quarter of 2001. The adverse impact
of  September  11 was  less  significant  in the  fourth  quarter  of  2001  and
management  believes that the fourth  quarter of 2001 also  benefited from other
short-term economic stimuli. The impact of these factors on our business and the
results of  operations  for the third  quarter  and nine  months of 2002 is more
fully discussed below.

      The  components of revenue and revenue  growth  (declines),  for the third
quarter of 2002 compared to the third quarter of 2001, in our primary geographic
markets are summarized below ($ in millions):

                                                 $ Revenue          % Growth
                                                 ---------          --------
      United States ....................          $  991.5              19.3%
      United Kingdom ...................             206.4              13.8%
      Euro Markets .....................             345.4               4.2%
      Other ............................             225.2              (0.9)%
                                                  --------          --------
      Total ............................          $1,768.5              12.6%
                                                  ========          ========

      As indicated, foreign exchange impacts increased our international revenue
by  $46.4  million  during  the  quarter  ended  September  30,  2002.  The most
significant  impacts resulted from the strengthening of the Euro and the British
Pound against the U.S.  dollar,  as our operations in these markets  represented
over  70.0% of our  international  revenue.  This was  partially  offset  by the
strengthening of the U.S. dollar against the Brazilian Real.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS (Continued)

      We monitor revenue across a broad range of disciplines and group them into
the  following  four  categories:   traditional  media   advertising,   customer
relationship management ("CRM"), public relations and specialty  communications.
Traditional media advertising  revenue  represented 42.4%, or $749.4 million, of
our worldwide  revenue  during the third  quarter of 2002.  The remainder of our
revenue,  57.6%,  or $1,019.1  million,  was related to our other  marketing and
corporate  communications services. The breakdown of this other revenue was CRM:
33.9%,  or $599.0 million;  public  relations:  12.4%,  or $220.7  million;  and
specialty communication:  11.3%, or $199.4 million. Revenue in the third quarter
of 2002 when compared to the third quarter of 2001  increased by $51.1  million,
or 7.3% for traditional media advertising,  by $100.8 million, or 20.2% for CRM,
by $18.1 million,  or 9.0%, for public relations and by $27.3 million, or 15.9%,
for specialty communications.

      Operating  Expenses:  Our third quarter 2002 worldwide  operating expenses
increased $192.5 million, or 14.1%, to $1,557.1 million from $1,364.6 million in
the third quarter of 2001 as described below.

      Salary and service costs,  which are comprised of direct service costs and
salary related costs, increased by $179.4 million, or 17.7%, and represent 76.8%
of total  operating  expenses in the third  quarter of 2002 versus  74.5% in the
third quarter of 2001.  These  expenses  increased as a percentage of revenue to
67.6% in the third  quarter  of 2002 from  64.7% in the third  quarter  of 2001.
Salaries and incentive  compensation  costs decreased as a percentage of revenue
in the third  quarter  primarily  as a result  of  continuing  efforts  to align
staffing  with  current  work levels on a location by location  basis.  This was
off-set by increased  direct  service costs  resulting  primarily from increased
severance related costs and greater utilization of freelance labor. In addition,
as a result of the increase in our revenues as well as changes in the mix of our
revenues  in the  quarter on a  period-over-period  basis,  other  direct  costs
increased as a percentage  of revenue in the third  quarter of 2002  compared to
the third quarter of 2001.

      Office and general  expenses  increased by $13.1 million,  or 3.7%, in the
third  quarter  of 2002.  Office  and  general  expenses  primarily  consist  of
occupancy costs,  general office service costs,  technology costs,  depreciation
and amortization and bad debt expense.  These costs  represented  about 23.2% of
our total  operating  costs in the third  quarter of 2002,  versus  25.5% in the
third  quarter of 2001.  This decrease is primarily the result of our efforts to
better align costs with business levels on a location by location basis.

      For the foregoing reasons,  our operating margin decreased to 12.0% in the
third quarter of 2002, from 13.1% in the same period in 2001.

      Net  Interest  Expense:  Our net interest  expense  decreased in the third
quarter of 2002 to $5.6 million, compared to $18.1 million in the same period in
2001. Our gross interest expense decreased by $13.9 million to $10.4 million. Of
this decrease,  $3.2 million was  attributable to the conversion of $230 million
aggregate  principal amount of our 2 1/4% convertible notes in December of 2001.
The balance of the  reduction was  attributable  to generally  lower  short-term
interest  rates as compared to the prior year,  the issuance in February 2001 of
the $850.0 million

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS (Continued)

Liquid  Yield  Option  Notes as to which  substantially  all of the related debt
issuance costs were amortized in prior periods and the issuance in March 2002 of
the $900.0 million principal Zero Coupon Zero Yield Convertible  Notes. This was
partially  off-set by increased daily average  outstanding debt levels resulting
primarily from our repurchase of common stock in the first quarter of 2002.

      Income Taxes: Our consolidated  effective income tax rate was 33.9% in the
third quarter of 2002,  as compared to 35.6% in the third quarter of 2001.  This
reduction  reflects the  realization  of our recently  implemented  tax planning
initiatives.

      Earnings Per Share (EPS): For the foregoing reasons, our net income in the
third quarter of 2002  increased  10.6% to $126.1 million from $114.0 million in
the third quarter of 2001.  Our diluted  earnings per share  increased  11.5% to
$0.68 in the third quarter of 2002, compared to $0.61 in the prior year period.

Nine Months 2002 Compared to Nine Months 2001

      Revenue:  Our consolidated  worldwide  revenue in the first nine months of
2002  increased by $498.6  million,  or 10.1% to $5,417.5  million from $4,918.9
million in the first nine  months of 2001.  The effect of  acquisitions,  net of

The components and percentages are calculated as follows:

      o     The  foreign  exchange  impact  shown  in  the  table  component  is
            calculated by first  converting the current  period's local currency
            revenue using the average  exchange rates from the equivalent  prior
            period  to  arrive  at a  constant  currency  revenue  (in this case
            $5,387.3  million for the Total  column in the  table).  The foreign
            exchange  impact equals the  difference  between the current  period
            revenue in U.S.  dollars and the current  period revenue in constant
            currency (in this case $5,417.5  million less  $5,387.3  million for
            the Total column in the table).

      o     The  acquisition  component  shown  in the  table is  calculated  by
            aggregating  the  applicable  prior  period  revenue of the acquired
            businesses.  Netted  against  this  number  is  the  revenue  of any
            business  included in the prior  period  reported  revenue  that was
            disposed of subsequent to the prior period.

      o     The  organic   component   shown  in  the  table  is  calculated  by

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS (Continued)

         The components of revenue and revenue growth (declines), for the nine
months 2002 compared to the nine months 2001, in our primary geographic markets
are summarized below ($ in millions):

                                                 $ Revenue           % Growth
                                                 ---------           --------
      United States ....................          $3,131.1              18.0%
      United Kingdom ...................             584.5               0.9%
      Euro Markets .....................           1,025.6               3.4%
      Other ............................             676.3              (2.8)%
                                                  --------          --------
      Total ............................          $5,417.5              10.1%
                                                  ========          ========

      As indicated, foreign exchange impacts increased our international revenue
by $30.2 million during the nine months ended September 30, 2002, increasing our
international  growth by 1.3%.  The most  significant  impact  resulted from the
strengthening  in the second and third  quarters of 2002  compared to the second
and third  quarters of 2001,  of the Euro and the British Pound against the U.S.
dollar  as our  operations  in  these  markets  represented  over  70.0%  of our
international revenue,  partially offset by the strengthening of the U.S. dollar
against the Brazilian Real.

      Traditional  media  advertising  revenue  represented  43.4%,  or $2,349.1
million,  of our  worldwide  revenue  during the first nine months of 2002.  The
remainder of our revenue,  56.6%, or $3,068.4 million,  was related to our other
marketing and  corporate  communications  services.  The breakdown of this other
revenue was CRM: 31.6%, or $1,710.6 million; public relations:  12.8%, or $694.0
million; and specialty communications:  12.2%, or $663.8 million. Revenue in the
first  nine  months  of 2002 when  compared  to the  first  nine  months of 2001
increased by $184.0  million,  or 8.5% for  traditional  media  advertising,  by
$243.9  million,  or 16.6%,  for CRM,  decreased by $34.7 million,  or 4.8%, for
public  relations  and  increased by $105.3  million,  or 18.9%,  for  specialty
communications.

      Operating  Expenses:  During  the  first  nine  months  of 2002  worldwide
operating expenses increased $462.4 million,  or 11.1%, to $4,646.7 million from
$4,184.3 million in the first nine months of 2001 as described below.

      Salary and service costs,  which are comprised of direct service costs and
salary related costs, increased by $454.8 million, or 14.5%, and represent 77.3%
of total operating expenses in the first nine months of 2002 versus 74.9% in the
first nine months of 2001.  These expenses  increased as a percentage of revenue
to 66.3% in the first nine months of 2002 from 63.7% in the first nine months of
2001.  Salaries and incentive  compensation  costs  decreased as a percentage of
revenue in the first nine  months of 2002  primarily  as a result of  continuing
efforts to align  staffing  with  current  work levels on a location by location
basis.  This was off-set by increased  direct service costs resulting  primarily
from  increased  severance  related costs and greater  utilization  of freelance
labor.  In  addition,  as a result of the  increase  in our  revenues as well as
changes  in  the  mix  of  our   revenues   in  the  first  nine   months  on  a
period-over-period  basis,  other  direct costs  increased  as a  percentage  of
revenue in the first nine  months of 2002  compared  to the first nine months of
2001.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS (Continued)

      Office and general  expenses  increased by $7.6  million,  or 0.7%, in the
first nine  months of 2002.  Office and general  expenses,  similar to the third
quarter alone, represented about 22.7% of our total operating costs in the first
nine  months  of 2002  versus  25.1%  for the first  nine  months of 2001.  This
decrease  is  primarily  the result of our  efforts to better  align  costs with
business levels on a location by location basis.

      For the foregoing reasons,  our operating margin decreased to 14.2% in the
first nine months of 2002, from 14.9% in the same period in 2001.

      Net Interest Expense: Our net interest expense decreased in the first nine
months of 2002 to $22.8 million, as compared to $57.9 million in the same period
in 2001. Our gross interest expense decreased by $35.9 million to $34.9 million.
Of this decrease in gross interest expense, $9.6 million was attributable to the
conversion of our $230.0 million  aggregate  principal amount 2 1/4% convertible
notes in December of 2001;  the balance of the  reduction  was  attributable  to
generally  lower  short-term  interest  rates as compared to the prior year, the
issuance in February  2001 of $850.0  million  Liquid  Yield  Option notes as to
which  substantially  all of the related debt issuance  costs were  amortized in
prior  periods and the  issuance in March 2002 of the $900.0  million  principal
Zero Coupon Zero Yield Convertible notes. This was partially offset by increased
daily average outstanding debt levels resulting primarily from our repurchase of
common stock in the first quarter of 2002.

      Income Taxes: Our consolidated  effective income tax rate was 36.3% in the
first nine  months of 2002,  as  compared  to 36.9% in the first nine  months of
2001.  This decrease was primarily  due to the  realization  of our tax planning
initiatives implemented during the third quarter of 2002.

      Earnings Per Share (EPS): For the foregoing reasons, our net income in the
first nine months of 2002 increased  10.3% to $442.0 million from $400.8 million
in the first nine months of 2001. Our diluted  earnings per share increased 9.8%
to $2.36 in the first nine  months of 2002,  compared to $2.15 in the prior year
period.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS (Continued)

Critical Accounting Policies and New Accounting Pronouncements

      To assist in better understanding our financial statements and the related
management's discussion and analysis of those results, readers are encouraged to
review  our  summary  of  critical   accounting   policies  and  new  accounting
pronouncements  included in Item 2 of our Quarterly  Report on Form 10-Q for the
quarter  ended June 30, 2002 and consider  this  information  together  with our
discussion of critical accounting policies in the MD&A in our 2001 10-K, as well
as our consolidated  financial  statements and the related notes included in our
2001 10-K for a more complete understanding of all of our accounting policies.

Contingent Acquisition Obligations

      As is typical in our business,  certain of our acquisitions are structured
as "earn-outs". We utilize earn-out structures in an effort to minimize the risk
to  the  Company  associated  with  potential  future  negative  changes  in the
performance  of the acquired  entity.  We estimate that the amount of contingent
future earn-out payments, assuming that the acquired businesses perform over the
relevant  earn-out  periods  at their  current  profit  levels,  that we will be
required to make for prior  acquisitions  is $452.3  million as of September 30,
2002. The ultimate  amounts  payable are dependent upon future  results,  and in
accordance  with GAAP,  we have not recorded a liability  for these items on our
balance  sheet.  Actual  results can differ from these  estimates and the actual
amounts that we pay will be different from these  estimates.  These  obligations
change from period to period as a result of  earn-out  payments  made during the
current  period,  changes in the  previous  estimate of the  acquired  entities'
performances,  changes  in  foreign  exchange  rates  and  the  addition  of new
contingent obligations resulting from acquisitions with earn-out structures that
were completed in the current period.  These differences  could be material.  We
estimate these obligations are as follows:

      In  addition,  owners of  interests  in  certain  of our  subsidiaries  or
affiliates  have the right in certain  circumstances  to require us to  purchase
additional  ownership  stakes which we estimate,  assuming that the subsidiaries
and affiliates perform over the relevant periods at their current profit levels,
could  require us in future  periods to pay an  additional  aggregate  of $206.3
million,  $96.4 million of which relates to currently  exercisable  rights.  The
ultimate amount payable in the future relating to these  transactions  will vary
because it is  dependent  on the future  results of  operations  of the  subject
businesses and the timing of when these rights are exercised. The actual amounts
that we pay will be different from these estimates.  These  differences could be
material.  We estimate the  obligations  that exist for these  agreements are as
follows:

Liquidity and Capital Resources

      Liquidity:  At  September  30,  2002,  our cash and cash  equivalents  and
short-term  investments  totaled  $392.6  million  and we had  $1,526.0  million
available to us under committed  credit  facilities.  We also had $368.0 million
available under uncommitted credit facilities.

      Consistent  with our  historical  trends in the first  nine  months of the
year, we had negative cash flow from operations of $232.7 million. This compares
to a decrease of $409.5 million in the comparable  nine-month  period last year.
This is primarily as a result of payments of accrued incentive compensation, tax
payments  and  payments to the media on behalf of  clients,  as well as seasonal
year-end  reductions  of our  current  liabilities  and  increases  in  billable
production  orders  partially  off-set by a decrease in accounts  receivable  at
September   30,   2002   compared   to  December   31,   2001.   Cash  used  for
acquisition-related  expenditures  was $342.5  million.  In addition,  we issued
$900.0  million  aggregate  principal  amount of Zero Coupon Zero Yield notes in
March 2002 and we  repurchased  $368.8 million of common stock with a portion of
the proceeds.  This resulted in an overall decrease in cash and cash equivalents
of $114.5 million for the nine month period ended September 30, 2002.

      Capital  Resources:  We maintain two revolving credit  facilities with two
consortia of banks. We have a $1,600.0 million 364-day revolving credit facility
with a consortium of banks for which Citibank N.A. acts as administrative  agent
and Salomon Smith Barney Inc. acts as lead arranger.  The consortium consists of
23  banks.  Other  significant  lending  institutions  include  The Bank of Nova
Scotia,  JPMorgan Chase Bank,  Fleet National Bank,  HSBC Bank USA and San Paolo
IMI S.p.A. The facility,  which can be drawn down at any time, also supports the
issuance of up to $1,500.0 million of commercial paper, and subject to obtaining
additional commitments may be increased up to $1,800.0 million. At September 30,
2002, we had issued and  outstanding  $200.0 million of commercial  paper all of
which is classified as long-term  debt. We have the right to convert all amounts
outstanding at expiration on April 25, 2003, into a one-year term loan.

      We also have a $500.0  million 5-year  revolving  credit  facility,  which
expires on June 30, 2003,  with a similar  consortium  of 13 banks for which ABN
AMRO Bank acts as agent. Other significant lending  institutions include Bank of
America,  HSBC, JP Morgan Chase and Wachovia.  We had $374.0 million outstanding
under this facility at September 30, 2002.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS (Continued)

      At  September  30,  2002,  we had a total of  $1,750.0  million  aggregate
principal  amount of convertible  notes  outstanding,  including  $850.0 million
Liquid Yield  Option  30-year  notes,  which were issued in February  2001,  and
$900.0 million Zero Coupon Zero Yield 30-year notes,  which were issued in March
2002, as well as,  short-term  bank loans of $95.0  million.  The holders of our
Liquid  Yield Option  notes have the right to cause us to  repurchase  up to the
entire  $850.0  million  aggregate  face of the notes in  February  2003 and the
holders  of our Zero  Coupon  Zero  Yield  notes  have the  right to cause us to
repurchase up to the entire $900.0 million aggregate face of the notes in August
of 2003.

      Below is a summary of our debt  position  as of  September  30, 2002 ($ in
millions):

      Debt:
        Bank loans (due less than 1 year).............................  $   95.0
        $500 Million Revolver - due June 30, 2003.....................     374.0
        Commercial paper issued under 364 Day Facility................     200.0
        5.20 % Euro Notes - due June 24, 2005.........................     151.0
        Convertible Notes - due February 7, 2031......................     850.0
        Convertible Notes - due July 31, 2032.........................     900.0
        Loan Notes and Sundry - various through 2012..................      65.0
                                                                        --------
     Total Debt.......................................................  $2,635.0
                                                                        ========

On November 14,  2002,  we entered into a new 3-year  $800.0  million  revolving
credit  facility  which  matures  November 14, 2005 and a new  $1,000.0  million
364-day  revolving  credit  facility  which matures on November 13, 2003.  These
facilities  replaced the existing  facilities that are described in Note 8 which
were due to mature in the second quarter of 2003.  Both  facilities  provide for
credit  support of the Company's  existing  $1,500.0  million  commercial  paper
program.  The new facilities have substantially the same terms as had previously
been in effect.  The 364-day  facility  continues  to include a provision  which
allows the Company to convert  all  amounts  outstanding  at  expiration  of the
facility into a one-year term loan.  The  consortium of banks  providing the new
facilities had previously participated in the facilities that were replaced.

      We believe that our operating cash flow combined with  availability  under
our  revolving  credit  facilities  and our access to the  capital  markets  are
sufficient  to support our  foreseeable  cash  requirements,  including  working
capital,  capital  expenditures,   future  acquisitions,   earn-outs  and  other
contingent  payments,  dividends,  debt  maturities and possible debt repurchase
obligations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

      Our results of  operations  are  subject to the risk of currency  exchange
rate  fluctuations  related to our international  operations.  Our net income is
subject to risk from the  translation of the revenue and expenses of our foreign
operations,  which are generally denominated in the local currency.  The effects
of currency exchange rate fluctuation on our third quarter and first nine months
results of operations are discussed on pages 13 and 17 of this report. We do not
hedge  these  exposures  against  the U.S.  dollar in the  normal  course of our
business.  We  do,  however,  conduct  global  treasury  operations  to  improve
liquidity and manage third party interest expense centrally. As an integral part
of these operations, we enter into short-term forward foreign exchange contracts
to hedge intercompany cash movements between subsidiaries operating in different
currency  markets.  While our agencies  operate in more than 100  countries  and
invoice clients in more than 70 different  currencies,  our major  international
markets are the E.U., the United Kingdom, Japan, Brazil and Canada.

      Our 2001 10-K  provides a more  detailed  discussion  of the market  risks
affecting our  operations.  As of June 30, 2002, no material change had occurred
in our market risks, as compared to the disclosure in our 2001 10-K.

Forward-Looking Statements

      "Management's  Discussion and Analysis of Financial  Condition and Results
of Operations" and "Quantitative and Qualitative  Disclosures About Market Risk"
set  forth  in  this  report  contain   disclosures  which  are  forward-looking
statements  within the meaning of the federal  securities laws.  Forward-looking
statements  include all  statements  that do not relate  solely to historical or
current facts,  and in some instances are  identifiable by the use of words such
as "may," "will," "expect,"  "project,"  "estimate,"  "anticipate,"  "envisage,"
"plan" or  "continue."  These  forward-looking  statements  are  based  upon our
current plans or expectations and are subject to a number of  uncertainties  and
risks that could significantly  affect current plans and anticipated actions and
our future financial condition and results. The uncertainties and risks include,
but are not  limited to,  changes in general  economic  conditions,  competitive
factors,  client communication  requirements,  the hiring and retention of human
resources and other  factors.  In addition,  our  international  operations  are
subject to the risk of  currency  fluctuations,  exchange  controls  and similar
risks discussed above. As a consequence,  current plans, anticipated actions and
future  financial  condition and results may differ from those  expressed in any
forward-looking statements made by us or on our behalf.


                                       23


ITEM 4. CONTROLS AND DISCLOSURE

      We maintain  disclosure  controls and  procedures  designed to ensure that
information required to be included in our SEC reports is recorded, analyzed and
reported within  applicable time periods.  During the 90-day period prior to the
filing of this report,  we conducted an evaluation,  under the  supervision  and
with the  participation  of our  management,  including  our CEO and CFO, of the
effectiveness  of  our  disclosure  controls  and  procedures.   Based  on  that
evaluation,  our CEO and CFO  concluded  that they believe  that our  disclosure
controls  and  procedures  are  effective  to  ensure  recording,  analysis  and
reporting of information  required to be included in our SEC reports on a timely
basis. There have been no significant  changes in our internal controls or other
factors  that  could  be  reasonably   expected  to  significantly   affect  the
effectiveness of these controls since that evaluation was completed.

                                  CERTIFICATION

I, John Wren, certify that:

      1. I have  reviewed  this  quarterly  report on Form 10-Q of Omnicom Group
Inc.;

      2. Based on my  knowledge,  this  quarterly  report  does not  contain any
untrue  statement of a material fact or omit to state a material fact  necessary
in order to make the statements made, in light of the circumstances  under which
such  statements were made, not misleading with respect to the period covered by
this quarterly report;

      3. Based on my knowledge,  the financial  statements,  and other financial
information  included in this quarterly  report,  fairly present in all material
respects the financial  condition,  results of operations  and cash flows of the
registrant as of, and for, the periods presented in this quarterly report;

      4. The  registrant's  other  certifying  officer and I are responsible for
establishing and maintaining  disclosure  controls and procedures (as defined in
Exchange Act Rules 13a-14 and 15d-14) for the registrant and we have:

      a)    designed  such  disclosure  controls and  procedures  to ensure that
            material  information  relating  to the  registrant,  including  its
            consolidated  subsidiaries,  is made  known to us by  others  within
            those  entities,  particularly  during  the  period  in  which  this
            quarterly report is being prepared;

      b)    evaluated the effectiveness of the registrant's  disclosure controls
            and  procedures as of a date within 90 days prior to the filing date
            of this quarterly report (the "Evaluation Date"); and

      c)    presented  in  this  quarterly  report  our  conclusions  about  the
            effectiveness of the disclosure controls and procedures based on our
            evaluation as of the Evaluation Date;

      5. The registrant's other certifying  officer and I have disclosed,  based
on our most  recent  evaluation,  to the  registrant's  auditors  and the  audit
committee  of  registrant's  board  of  directors  (or  persons  performing  the
equivalent function):

      a)    all significant  deficiencies in the design or operation of internal
            controls which could adversely  affect the  registrant's  ability to
            record,  process,  summarize  and  report  financial  data  and have
            identified for the registrant's  auditors any material weaknesses in
            internal controls; and

      b)    any fraud,  whether or not  material,  that  involves  management or
            other  employees  who have a  significant  role in the  registrant's
            internal controls; and

      6. The registrant's  other certifying officer and I have indicated in this
quarterly  report  whether or not there  were  significant  changes in  internal
controls or in other factors that could  significantly  affect internal controls
subsequent to the date of our most recent  evaluation,  including any corrective
actions with regard to significant deficiencies and material weaknesses.
