              statements are an integral part of these statements.


                                       3



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

1.    The consolidated  condensed interim financial  statements  included herein
      have been prepared by the Company,  without  audit,  pursuant to the rules
      and  regulations  of  the  Securities  and  Exchange  Commission.  Certain
      information  and  footnote  disclosures  normally  included  in  financial
      statements  prepared in  accordance  with  generally  accepted  accounting
      principles in the United States have been condensed or omitted pursuant to
      such rules and regulations.

2.    These 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,
      2000 and  December  31,  2000  reported  amounts to conform  them with the
      September 30, 2001 presentation.  These consolidated  condensed  financial
      statements  should be read in conjunction with the consolidated  financial
      statements  and notes thereto  included in the Company's  annual report on
      Form 10-K for the year ended December 31, 2000.

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  and,  if  dilutive,
      adjusted  for  the  assumed   conversion  of  the  Company's   Convertible
      Subordinated Debentures (the "Debentures") and the assumed increase in net
      income for the after tax  interest  cost of the  Debentures.  In  December
      2000,  the 4 1/4% Convertible  Subordinated  Debentures  were  called  for
      redemption  and  subsequently  converted  by holders into shares of common
      stock.  The  additional  shares  are  included  in shares  outstanding  at
      September 30, 2001. In determining if the remaining Debentures outstanding
      were dilutive at September 30, 2001 and 2000, the Debentures  were assumed
      to have been  converted for the entire  period.  For purposes of computing
      diluted  earnings per share for the three months ended  September 30, 2001
      and 2000,  respectively,  185,019,000  and  177,489,000  common shares and
      common  share   equivalents   were  assumed  to  have  been   outstanding.
      Additionally,  4,612,000 and 11,542,000 shares,  respectively were assumed
      to have been converted  related to the Debentures and the assumed increase
      in net income  used in the  computation  was  $2,499,000  and  $4,452,000,
      respectively. For purposes of computing diluted earnings per share for the
      nine months ended September 30, 2001 and 2000,  respectively,  184,960,000
      and 177,898,000 common shares and common share equivalents were assumed to
      have been  outstanding.  Additionally,  4,613,000 and  11,547,000  shares,
      respectively,   were  assumed  to  have  been  converted  related  to  the
      Debentures and the assumed  increase in net income used in the computation
      was $7,462,000 and $13,459,000, respectively. The number of shares used in
      the computations of basic and diluted earnings per share were as follows:

7.    In May 2001, the Company and an unrelated third party formed a new holding
      company.  The  Company  contributed   investments  in  several  companies,
      primarily in the e-services  industry.  The co-investor  contributed cash.
      Upon  contribution to the holding  company,  the Company  reclassified its
      investments  from long-term  investments  and investments in affiliates to
      cost  basis   investments  and  included  them  in  other  assets  in  the
      accompanying  balance  sheet.  No  gain  or  loss  was  recognized  on the
      transaction.  The  Company  holds  a  preferred  equity  interest  and the
      co-investor holds the common equity interest in the holding company.

            Management  continually  monitors  the value of its  investments  to
      determine whether an other than temporary  impairment has occurred.  As of
      the period ended  September 30, 2001,  the carrying value of the Company's
      investments approximated its fair value.

8.    In the second quarter 2001, the Company  extended its 364-day,  $1 billion
      revolving  credit facility.  The facility,  which supports the issuance of
      commercial  paper, was renewed under  substantially  the same terms as had
      previously been in effect,  including a provision which allows the Company
      to convert all amounts  outstanding at expiration on April 25, 2002 into a
      one-year term loan. The Company also has a $500 million  5-year  revolving
      credit facility which expires on June 30, 2003.

            Amounts  outstanding  under these  revolving  credit  facilities  at
      September 30, 2001 were $1,028.1 million which was classified as long-term
      debt.

            The  Company  also had  short-term  bank  loans of $73.8  million at
      September   30,  2001,   primarily   comprised  of  bank   overdrafts   of
      international  subsidiaries  which are treated as unsecured loans pursuant
      to bank agreements.

            At September 30, 2001,  the Company had committed  unsecured  credit
      lines including the 364-day,  $1 billion revolving credit facility and the
      $500  million,  5-year  revolving  credit  facility  aggregating  $1,988.9
      million.  The  unused  portion  of credit  lines  was  $887.0  million  at
      September 30, 2001.

9.    In February  2001,  the Company  completed  the  issuance of $850  million
      aggregate  principal  amount of Liquid  Yield  Option  Notes  (LYONs)  due
      February 7, 2031.  The net proceeds  from the LYONs  offering  were $830.2
      million. The LYONs are unsecured,  unsubordinated  zero-coupon  securities
      that may be converted into common shares,  subject to specified conditions
      relating to the price of the  Company's  common  shares.  The LYONs had an
      issue  price of $1,000  per LYON and each LYON can be converted  into 9.09
      shares  of  the  Company's  common  stock,   which  yields  an  equivalent
      conversion price of $110.01 per share subject to antidilutive adjustments.

            The Company  may be required to redeem the LYONs on February  7th of
      each year until  maturity, with cash or common stock or a  combination  of
      both, at the Company's election.  Additionally, the Company has the option
      of redeeming the LYONs after February 7, 2006 for cash.

            After  February  7,  2006,  if the  Company's  stock  price  reaches
      specified thresholds,  the Company may be obligated to pay contingent cash
      interest  equal to the  amount of  dividends  the  Company  pays to common
      shareholders during the relevant period.

10.   In June 1998, the Financial  Accounting  Standards  Board ("FASB")  issued
      Statement of  Financial  Accounting  Standards  No. 133,  "Accounting  for
      Derivative  Instruments  and  Hedging  Activities"  ("SFAS  No.  133") (as
      amended by SFAS 138), which the Company adopted effective January 1, 2001.
      SFAS No. 133 requires that every derivative  instrument (including certain
      derivative  instruments  embedded in other  contracts)  be recorded in the
      balance sheet as either an asset or liability  measured at its fair value.
      Derivatives  that are not hedges must be  adjusted  to fair value  through
      income.  If the  derivative  is a hedge,  depending  on the  nature of the
      hedge,  changes in the fair  value of  derivatives  will  either be offset
      against the change in fair value of the hedged assets, liabilities or firm
      commitments through earnings or recognized in other  comprehensive  income
      until the hedged item is recognized in earnings.  The ineffective  portion
      of the change in fair value of a derivative used as a hedge is required to
      be immediately recognized in earnings.

            In  the first  quarter  of the year,  the  Company  recorded  a $2.9
      million after tax charge ($4.9 million pre-tax) for the cumulative  effect
      of adopting,  effective January 1, 2001, SFAS No. 133. The charge resulted
      from the Company's accounting for a hedge of its net yen investments.  The
      Company  utilized  a  cross  currency   contract  to  hedge  its  net  yen
      investments.   Consistent  with  the  Company's  policy  with  respect  to
      derivative  instruments and hedging activities and in accordance with SFAS
      No. 133, when the spot rate is declared as the  underlying  hedge of a net
      investment,  any  ineffectiveness  is  recorded  in  operating  income  or
      expense.  During the first  quarter of 2001,  the Company  terminated  the
      portion  of the  contract  that  gave  rise to the  ineffectiveness.  As a
      result, no measurable ineffectiveness will result for the remaining term.

            The  Company  also  uses  forward  contracts  to hedge  its  foreign
      currency intercompany  receivables and payables. The term of these forward
      contracts  is  typically  30 days.  These  contracts  are marked to market
      through earnings and the changes in market value are offset by the changes
      in the spot value of the foreign  currency  receivable  or  payable.  This

        NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued)

      accounting  is similar to the  accounting  applied  prior to adopting SFAS
      133. The changes in value are included in operating  income or expense and
      were not  material to results of  operations  for the three and nine month
      periods ended September 30, 2001.

11.   In June 2001, the Financial  Accounting  Standards  Board ("FASB")  issued
      Statements  of  Financial   Accounting   Standards   No.  141,   "Business
      Combinations"  ("SFAS No. 141") and Statement of Accounting  Standards No.
      142,  "Goodwill  and Other  Intangibles"  ("SFAS No.  142").  SFAS No. 141
      became effective June 30, 2001 and requires that all business combinations
      be accounted for using the purchase method of accounting. The Company does
      not believe  the effect of  adopting  SFAS No. 141 will be material to its
      financial statements.

            SFAS  No.  142  ends  the  requirement  to  amortize   goodwill  and
      intangible  assets with  indefinite  lives,  establishes  requirements  to
      identify  intangible  assets  that  will  continue  to  be  amortized  and
      clarifies the requirement to write down goodwill and intangible  assets to
      fair  value  based on a  determination  of  impairment.  SFAS  No.  142 is
      effective  on January 1, 2002.  However,  it contains  certain  transition
      provisions which became effective July 1, 2001. The transition  provisions
      were not material to the  Company's  results of  operations  for the three
      month period ended  September 30, 2001 and are not expected to be material
      to the Company's results of operations for the remainder of the year.

            The  Company  has a  significant  amount of  goodwill  and is in the
      process of analyzing the impact of adopting SFAS No. 142. During 2002, the
      Company  will  perform  the  first  of the  required  impairment  tests of
      goodwill and intangible assets. In addition, the FASB is in the process of
      clarifying  certain aspects of the new rules.  Accordingly,  the effect of
      adopting  SFAS No.  142 on the  earnings  and  financial  position  of the
      Company has not yet been determined.

ITEM 2.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITIONS  AND
         RESULTS OF OPERATIONS

Results of Operations

Third Quarter 2001 Compared to Third Quarter 2000

      Consolidated worldwide revenue increased 8.2% in the third quarter of 2001
to $1,571.0  million  compared to $1,452.5 million in the third quarter of 2000.
Consolidated  domestic  revenue  increased  7.1% in the third quarter of 2001 to
$831.1  million  compared  to  $775.7  million  in the  third  quarter  of 2000.
Consolidated  international  revenue increased 9.3% in the third quarter of 2001
to $739.9  million  compared to $676.8 million in the third quarter of 2000. The
effect of acquisitions, net of divestitures, increased worldwide revenue by 5.7%
and changes in the foreign exchange value of the U.S. dollar decreased worldwide
revenue by 2.0%. The remaining 4.5% increase in consolidated  worldwide  revenue
was due to the growth of existing businesses, including net new business wins.

      Worldwide  operating expenses,  including net interest expense,  increased
8.8% in the third  quarter of 2001 to  $1,406.9  million  compared  to  $1,293.8
million  in the  third  quarter  of 2000.  The  effect of  acquisitions,  net of
divestitures,  increased worldwide operating expenses by 6.0% and changes in the
foreign exchange value of the U.S. dollar decreased worldwide operating expenses
by 2.0%. The remaining  increase of 4.8%  primarily  reflects  increased  client
services expenditures to support the increased revenue base.

      Net  interest  expense  decreased  in the third  quarter  of 2001 to $18.1
million as compared to $23.4  million in the same period in 2000.  The reduction
in interest  expense is the result of the  conversion  of our 4 1/4% Convertible
Subordinated Debentures at the end of last year and lower overall interest rates
compared to the prior year period.

      Operating margin,  which excludes net interest  expense,  was 11.6% in the
third  quarter of 2001 as compared  to 12.5% in the same period in 2000.  Pretax
profit margin was 10.4% in the third quarter of 2001 as compared to 10.9% in the
same period in 2000.  The decrease in operating  margin and pretax profit margin
was driven  primarily by lower than expected revenue growth in the third quarter
which  management  believes was due, in part,  to the tragic events of September
11, 2001.

      The  effective  income tax rate was 39.2% in the third  quarter of 2001 as
compared  to 40.7% in the third  quarter of 2000.  This  decrease  is due to the
Company's  continuing  implementation  of tax  planning  efforts.

      The  decrease in equity in  affiliates  is  primarily  the result of lower
profits for the three month  period  earned by certain  affiliates  in which the
Company owns less than a 50% equity  interest and the  acquisition of additional
ownership  interests in certain affiliates that resulted in their  consolidation
in the September 30, 2001 financial statements.

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

      The  decrease  in  minority  interest  expense is  primarily  due to lower
earnings and the acquisition of additional ownership interests.

      Net income  increased 7.8% to $92.4 million and diluted earnings per share
increased  4.2% to $0.50 in the third  quarter  of 2001,  as  compared  to $85.7
million and $0.48 per share, respectively, in the same period in 2000.

Nine Months 2001 Compared to Nine Months 2000

      Consolidated worldwide revenue increased 13.0% in the first nine months of
2001 to $4,918.9  million  compared to $4,351.8 million in the first nine months
of 2000.  Consolidated domestic revenue increased 15.4% in the first nine months
of 2001 to $2,653.0  million  compared to $2,298.4 million in the same period in
2000.  Consolidated  international  revenue  increased  10.3% in the first  nine
months of 2001,  to $2,265.9  million  compared to $2,053.4  million in the same
period in 2000.  The  effect of  acquisitions,  net of  divestitures,  increased
worldwide revenues by 6.6% and changes in the foreign exchange value of the U.S.
dollar  decreased  worldwide  revenue by 3.6%.  The remaining  10.0% increase in
consolidated worldwide revenues was due to the growth of existing businesses.

      Worldwide  operating expenses,  including net interest expense,  increased
13.4% in the first nine months of 2001 to $4,312.2 million, compared to $3,803.0
million in the first nine  months of 2000.  The effect of  acquisitions,  net of
divestitures,  increased worldwide operating expenses by 6.5% and changes in the
foreign exchange value of the U.S. dollar decreased worldwide operating expenses
by 3.6%. The remaining  increase of 10.5% primarily  reflects increased salaries
and client  services  expenditures  in support of an increased  revenue base, as
well as the cumulative effect of adopting SFAS 133.

      Net interest  expense  increased to $57.9 million in the first nine months
of 2001  compared  to $50.9  million in the same period in 2000.  This  increase
primarily reflects increased debt levels used primarily to fund acquisitions and
share  repurchases,  offset by reductions in interest expense resulting from the
conversion of our 4 1/4% Convertible  Subordinated Debentures at the end of last
year and lower overall interest rates.

      Operating margin,  which excludes net interest expense,  was 13.5% for the
first  nine  months  of 2001 as  compared  to 13.8% in the same  period in 2000.
Pretax profit margin was 12.3% for the first nine months of 2001, as compared to
12.6% in the  same  period  in  2000,  excluding  the  realized  gain on sale of
Razorfish shares.  The decrease in operating margin and pretax profit margin was
driven  primarily by lower than expected  revenue growth in the third quarter of
2001,  which  management  believes  was due,  in part,  to the tragic  events of
September 11, 2001.

      The effective  income tax rate was 39.5% for the first nine months of 2001
as  compared  to 40.9%  for the same  period  in 2000.  The  decrease  is due to
continued tax planning efforts

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

and to the impact of the gain on the sale of Razorfish  shares last year,  which
resulted in a higher rate in the first three months of 2000.

      The  decrease  in equity in  affiliates  is  primarily  the  result of the
acquisition  of  additional  ownership  interests  in  certain  affiliates  that
resulted in their  consolidation in the September 30, 2001 financial  statements
and lower  profits for the nine month  period  earned by certain  affiliates  in
which the Company owns less than a 50% equity interest.

      The  decrease  in  minority  interest  expense is  primarily  due to lower
earnings and acquisitions of additional ownership interests.

      Excluding the gain on sale of Razorfish shares, net income increased 15.8%
to $339.0 million in the first nine months of 2001 as compared to $292.8 million
in the same period in 2000 and diluted  earnings  per share  increased  13.0% to
$1.83 in the first nine  months of 2001 as  compared to $1.62 in the same period
in 2000. Including this gain, net income decreased 4.9% to $339.0 million in the
first nine months of 2001 as  compared  to $356.6  million in the same period in
2000 and diluted EPS decreased 6.2% from $1.95 for the same period in 2000.

Capital Resources and Liquidity

      Cash and cash  equivalents  at  September  30,  2001  decreased  to $421.1
million  from $516.8  million at December  31, 2000.  The  relationship  between
payables to the media and suppliers and receivables  from clients,  at September
30, 2001, is consistent with industry norms and our experience in prior periods.

      On April 26, 2001,  we renewed our $1 billion,  364-day  revolving  credit
facility,  which  supports the issuance of commercial  paper.  This facility was
renewed under  substantially the same terms as previously  existed,  including a
provision  that allows us to convert all amounts  outstanding  at  expiration on
April 25, 2002,  into a one-year term loan.  The Company also has a $500 million
5-year  revolving   credit  facility  which  expires  June  30,  2003.   Amounts
outstanding  under these revolving credit  facilities at September 30, 2001 were
$1,028.1 million which was classified as long-term debt.

      At September 30, 2001,  the Company had committed  unsecured  credit lines
including  the  364-day,  $1  billion  revolving  credit  facility  and the $500
million,  5-year revolving credit facility  aggregating  $1,988.9  million.  The
unused portion of credit lines was $887.0 million at September 30, 2001.

      In February  2001,  the Company  completed  the  issuance of $850  million
aggregate  principal amount of Liquid Yield Option Notes (LYONs) due February 7,
2031.  The net proceeds from the LYONs offering were $830.2  million.  The LYONs
are unsecured,  unsubordinated zero-coupon securities that may be converted into
common  shares,  subject to  specified  conditions  relating to the price of the
Company's common shares. The LYONs had an issue price of $1000 per LYON and each
LYON can be converted  into 9.09 shares of the  Company's  common  stock,  which
yields  an  equivalent   conversion  price  of  $110.01  per  share  subject  to
antidilutive adjustments.

      The Company  may be  required to redeem the LYONs on February  7th of each
year until maturity,  with cash or common stock or a combination of both, at the
Company's  election.  Additionally,  the Company has the option of redeeming the
LYONs after February 7, 2006 for cash.

      After  February 7, 2006,  if the Company's  stock price reaches  specified
thresholds,  the Company may be obligated to pay contingent  cash interest equal
to the amount of dividends  the Company pays to common  shareholders  during the
relevant period.

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

      Management  believes the aggregate lines of credit available and cash flow
from operations provide us with sufficient liquidity and are adequate to support
foreseeable operating requirements.

Long-Term Investments

      As of December 31, 2000, the Company had  investments  available for sale,
which were  comprised  of certain  minority  interests in public  marketing  and
corporate  communication  companies  that  specialize in digital media and other
interactive services.

      During  the first  quarter  ended  March 31,  2001,  we sold our  minority
interests in certain public companies that we held as investments.

      In May 2001, the Company and an unrelated third party formed a new holding
company. The Company contributed investments in several companies,  primarily in
the e-services industry. The co-investor  contributed cash. Upon contribution to
the holding  company,  the Company  reclassified  its investments from long-term
investments and investments in affiliates to cost basis investments and included
them in other  assets in the  accompanying  balance  sheet.  No gain or loss was
recognized on the transaction. The Company holds a preferred equity interest and
the co-investor holds the common equity interest in the holding company.

      Management  continually monitors the value of its investments to determine
whether an other than temporary impairment has occurred.  As of the period ended
September 30, 2001, the carrying value of the Company's investments approximated
its fair value.

New Accounting Pronouncements

      In June 2001, the Financial  Accounting  Standards  Board ("FASB")  issued
Statements of Financial  Accounting  Standards No. 141, "Business  Combinations"
("SFAS No. 141") and  Statement of Accounting  Standards No. 142,  "Goodwill and
Other Intangibles" ("SFAS No. 142"). SFAS No. 141 became effective June 30, 2001
and requires that all business  combinations be accounted for using the purchase
method of  accounting.  The Company does not believe the effect of adopting SFAS
No. 141 will be material to its financial statements.

      SFAS No. 142 ends the  requirement  to amortize  goodwill  and  intangible
assets with indefinite lives,  establishes  requirements to identify  intangible
assets that will continue to be amortized and clarifies the requirement to write
down goodwill and intangible  assets to fair value based on a  determination  of
impairment.  SFAS No. 142 is effective on January 1, 2002.  However, it contains
certain  transition  provisions which


                                       12



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

became  effective July 1, 2001. The transition  provisions  were not material to
the Company's  results of operations for the three month period ended  September
30,  2001 and are not  expected  to be  material  to the  Company's  results  of
operations for the remainder of the year.

      The Company has a significant  amount of goodwill and is in the process of
analyzing  the impact of adopting  SFAS No. 142.  During 2002,  the Company will
perform the first of the required  impairment  tests of goodwill and  intangible
assets. In addition, the FASB is in the process of clarifying certain aspects of
the new rules. Accordingly,  the effect of adopting SFAS No. 142 on the earnings
and financial position of the Company has not yet been determined.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

      Our market  risks  primarily  consist of the impact of changes in currency
exchange rates on assets and  liabilities of non-U.S.  operations and the impact
of changes in interest rates on debt.

      Our 2000 Form 10-K provides a more detailed discussion of the market risks
affecting  our  operations.  As of September  30, 2001,  no material  change had
occurred in our market risks, as compared to the disclosure in our Form 10-K for
the year ending December 31, 2000.

Forward-Looking Statements

      This  report  contains  various   statements  that  are   "forward-looking
statements" within the meaning of the federal  securities laws.  Forward-looking
statements  are  statements of  expectations  or beliefs as to future events and
other statements that do not relate solely to historical or current facts. These
forward-looking  statements are based upon our current plans or expectations and
are subject to a number of uncertainties  and risks. The uncertainties and risks
include,  but are not limited to, our future financial  condition and results of
operations,  changes in general economic  conditions,  competitive  factors, and
changes  to client  communication  requirements.  Actual  future  events  can be
expected  to  differ  from  our  current  expectations  and  beliefs  and  those
differences  may be in  actual  currency  fluctuations,  exchange  controls  and
similar risks discussed in the above and our Annual Report on Form 10-K for last
year.
