                       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  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 March 31, 2000
      and December 31, 2000 reported  amounts to conform them with the March 31,
      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 March
      31, 2001. In determining if the Debentures were dilutive at March 31, 2001
      and 2000,  the  Debentures  were  assumed to have been  converted  for the
      entire quarter.  For purposes of computing  diluted earnings per share for
      the three months ended March 31, 2001 and 2000, respectively,  183,809,000
      and  177,484,000  common  share  equivalents  were  assumed  to have  been
      outstanding.  Additionally,  4,614,000 and 11,552,000 shares, respectively
      were  assumed to have been  converted  related to the  Debentures  and the
      assumed  increase in net income used in the computation was $2,088,000 and
      $4,441,000, respectively. The number of shares used in the computations of
      basic and diluted earnings per share were as follows:

            During the three months  ended March 31, 2001,  the Company sold its
      minority   interests  in  several   public   companies  that  it  held  as
      investments.  The Company realized a pre-tax loss of $3,500,000 related to
      this transaction and comprehensive income for the period has been adjusted
      to reflect the reclassification of this loss from unrealized to realized.

            During the three months  ended March 31,  2001,  the market value of
      the  Company's  investments  in certain  public  marketing  and  corporate
      communication  companies declined.  Accordingly,  the Company adjusted the
      carrying  value of these  investments  to reflect  the market  value as of
      March 31, 2001 and recorded an unrealized  pre-tax loss of  $15,785,000 in
      comprehensive income.

            During the three  months  ended March 31,  2000,  the Company sold a
      portion of its ownership interest in Razorfish Inc. and realized a pre-tax
      gain of approximately $110 million.  Included in net income for the period
      is $63,826,000  related to this transaction and  comprehensive  income for
      the period has been adjusted to reflect the  reclassification  of the gain
      from unrealized to realized.

            In May 2001, the Company  contributed  to a new holding  company the
      equity of an entity  that  held its  investments  in  several  public  and
      private companies which had been classified as long term investments.  The
      investments  were  primarily  companies in the  e-services  industry.  The
      Company received 8.5% cumulative preferred stock for its contribution. The
      common stock of the new holding company is owned by a private equity fund.
      No gain or loss was recognized in the transaction.

6.    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 cash flow  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 a derivative's  change in fair value will be immediately  recognized in
      earnings.

            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 Yen net  investments.  The Company  utilized a cross currency
      contract (the "Contract") to hedge its Yen net investment. 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 which gave rise
      to the  ineffectiveness  and  recorded an  additional  after tax charge of
      $300,000 ($500,000 pre-tax). As a result of the termination of part of the
      Contract,  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, on average, 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  accounting  is similar to the  accounting  applied prior to adopting
      SFAS 133, as  amended.  The  changes in value are  included  in  operating
      income or expense and were not material.

7.    The Company's  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 through
      several  worldwide,  national and regional  independent agency brands. The
      businesses  exhibit  similar  economic  characteristics  driven

      from their  consistent  efforts to create  customer  driven  marketing and
      corporate   communications   and  services   that  build  their   clients'
      businesses.

            A summary of the Company's operations by geographic area as of March
      31, 2001 and 2000, and for the three months then ended is presented below:

8.    On April 26,  2001,  the Company  extended  its 364-day  revolving  credit
      facility.  The facility 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. Both
      facilities  allow for the issuance of commercial  paper, and on a combined
      basis, the Company can issue $1.0 billion in commercial paper.

            Amounts  outstanding  under the revolving credit facilities at March
      31, 2001 include loans of $300.0 million, and $559.0 million of commercial
      paper, both classified as long-term debt.

            The Company  also had  short-term  bank loans of $143.8 at March 31,
      2001,   primarily   comprised   of  bank   overdrafts   of   international
      subsidiaries,  which are  treated  as  unsecured  loans  pursuant  to bank
      agreements.

            At March 31, 2001, the Company had committed  unsecured credit lines
      aggregating  $1,843.0  million.  The unused  portion  of credit  lines was
      $840.2 at March 31, 2001.

9.    In February  2001,  the Company  completed the issuance of $850 million of
      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 our common shares.  The initial  conversion price

        CONDITIONS AND RESULTS OF OPERATIONS

Results of Operations

First Quarter 2001 Compared to First Quarter 2000

      Consolidated  worldwide  revenue  increased  16.1% in the first quarter of
2001 to $1,601.1  million  compared to $1,379.0  million in the first quarter of
2000. Consolidated domestic revenue increased 25.0% in the first quarter of 2001
to $896.6  million  compared  to $717.4  million  in the first  quarter of 2000.
Consolidated  international  revenue increased 6.5% in the first quarter of 2001
to $704.5  million  compared to $661.6 million in the first quarter of 2000. The
effect of acquisitions, net of divestitures, increased worldwide revenue by 6.6%
and changes in the foreign exchange value of the U.S. dollar decreased worldwide
revenue by 4.3%. The remaining 13.8% 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
16.6% in the first quarter of 2001  compared to the first  quarter of 2000.  The
effect of  acquisitions,  net of  divestitures,  increased  worldwide  operating
expenses by 6.9% and changes in the foreign  exchange  value of the U.S.  dollar
decreased  worldwide operating expenses by 4.3%. The remaining increase of 14.0%
reflects normal salary  increases and growth in client services  expenditures to
support the increased  revenue base and the  cumulative  effect of adopting SFAS
133.

      Net  interest  expense  increased  in the first  quarter  of 2001 to $20.3
million as compared to $11.3  million in the same period in 2000.  This increase
reflects  increased  debt levels used primarily to fund  acquisitions  and share
repurchases,  offset  by  reductions  in  interest  expense  resulting  from the
conversion of our 4.25%  Convertible  Subordinated  Debenture at the end of last
year and lower overall interest rates.

      The operating margin,  which excludes net interest  expense,  was 11.9% in
the  first  quarter  of 2001 as  compared  to 11.9% in the same  period in 2000.
Excluding the gain on sale of Razorfish  shares,  pretax profit margin was 10.7%
in the first quarter of 2001 as compared to 11.0% in the same period in 2000.

      The  effective  income tax rate was 39.6% in the first  quarter of 2001 as
compared  to  41.3%  in the  first  quarter  of 2000.  This  decrease  is due to
continued efforts to reduce our effective tax rate and to the impact of the gain
on sale of Razorfish  shares last year,  which resulted in a higher marginal tax
rate for the first quarter of 2000.

      The decrease in equity in affiliates is the result of the  acquisition  of
additional  ownership  interests in certain  affiliates  that  resulted in their
consolidation  in the March 31,  2001  financial  statements  and lower  profits
earned by certain companies in which we own less than a 50% equity interest.

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 the
acquisition  of additional  ownership  interests and lower earnings by companies
where minority interests exist.

      Excluding the gain on sale of Razorfish shares, net income increased 19.6%
to $95.3 million and diluted  earnings per share increased 15.6% to $0.52 in the
first quarter of 2001.  Including this gain, net income decreased 33.6% to $95.3
million in the first  quarter of 2001 as compared to $143.5  million in the same
period in 2000 and diluted  earnings per share  decreased  33.3% to $0.52 in the
current quarter compared to $0.78 in the prior year period.

Capital Resources and Liquidity

      Cash and cash  equivalents  at March 31, 2001  decreased to $420.7 million
from $516.8 million at December 31, 2000. The  relationship  between payables to
the media and suppliers  and  receivables  from  clients,  at March 31, 2001, is
consistent with industry norms.

      On April 26, 2001, we renewed our 364-day  revolving credit facility.  The
facility,  which  supports the issuance of commercial  paper,  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.  Together  with our $500  million  revolving  credit
facility, we can issue $1.0 billion in commercial paper.

      We also maintain relationships with a number of banks worldwide.  At March
31, 2001, we had $1,843.0  million in such unsecured  committed lines of credit,
of which $840.2 million was available.

      In February  2001,  we 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 our
common  shares,  subject to  specified  conditions  relating to the price of our
common  shares.  The initial  conversion  price is $110.01 per share  subject to
antidilutive  adjustment.  We may be required to redeem the LYONs after February
7, 2002 with cash or common stock or a  combination  of both,  at our  election.
Additionally,  we have the option of redeeming the LYONs after  February 7, 2006
for cash. Furthermore, we may be obligated to pay contingent cash interest after
February 7, 2006 equal to the amount of dividends we pay to common  shareholders
during  specified  six-month  periods,  if our  stock  price  reaches  specified
thresholds.

      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.

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

Long-Term Investments

      We have  investments  available-for-sale,  which are  comprised of certain
minority  interests in public  marketing and corporate  communication  companies
that  specialize in digital  media and other  interactive  services.  The market
value of the public companies are subject to a high degree of market volatility.
This  volatility  is  reflected  in  unrealized  gains and  losses  recorded  in
shareholders' equity as accumulated other comprehensive income.

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

      In May 2001,  we  contributed  to a new  holding  company the equity of an
entity that held our  investments in several public and private  companies which
had been classified as long term  investments.  The  investments  were primarily
companies in the  e-services  industry.  We received 8.5%  cumulative  preferred
stock for its contribution. The common stock of the new holding company is owned
by a private equity fund. No gain or loss was recognized in the transaction.

      Management   continually  monitors  the  value  of  these  investments  to
determine  whether an other than temporary  impairment  has occurred.  As of the
quarter  ended  March  31,  2001,  the  carrying  value  of  these   investments
approximated their fair value.

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 March 31, 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

      "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 no relate  solely to  historical or
current facts,  and can be identified 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 in
Item 3 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.
