              NOTES TO 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  ("GAAP") have been  condensed or omitted
      pursuant to these rules.

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 June 30, 2003 and December 31, 2003  reported  amounts to conform them
      to the June 30,  2004  presentation.  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,
      2003.

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

4.    In   accordance   with  SFAS  No.   123,   "Accounting   for  Stock  Based
      Compensation",  as amended by SFAS No. 148,  "Accounting  for  Stock-Based
      Compensation - Transition and  Disclosure,  an amendment of FASB Statement
      No.  123",  we  elected,   effective  January  1,  2004,  to  account  for
      stock-based  employee  compensation  using  the fair  value  method.  As a
      result,  the fair value of stock-based  employee  compensation,  including
      unvested  employee stock options issued and outstanding,  were recorded as
      an expense in the current  period  utilizing the  retroactive  restatement
      method as set forth in SFAS 148. Accordingly,  our results for the quarter
      and the six months  ended June 30,  2003 have been  restated  as if we had
      used  the  fair  value   method  to  account  for   stock-based   employee
      compensation.  Pre-tax  stock-based  employee  compensation  costs for the
      three  months  ended June 30,  2004 and 2003 were $30.0  million and $32.4
      million, respectively, and for the six months ended June 30, 2004 and 2003
      were $61.6 million and $67.1  million,  respectively.  Also, in connection
      with the  restatement,  our  December  31, 2003  balance  sheet  presented
      reflects an increase in the  deferred  tax benefit of $120.5  million,  an
      increase in additional  paid-in capital of $434.7 million,  an increase in
      unamortized stock compensation of $92.6 million and a decrease in retained
      earnings of $221.6 million.

            The table below presents a reconciliation of net income and earnings
      per share,  as reported,  to the restated  results for the quarter and the
      six months ended June 30, 2003.

5.    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 were
      made for any  series of our  zero-coupon  convertible  notes  because  the
      conversion  criteria have not been met. For purposes of computing  diluted
      earnings per share,  1,314,000 and 1,443,000 common share equivalents were
      assumed to be  outstanding  for the three months and six months ended June
      30, 2004, respectively.

            The  assumed  increase  in  net  income  related  to the  after  tax
      compensation  expense related to dividends on restricted shares was $224.0
      thousand and $302.0  thousand for the three months ended June 30, 2004 and
      2003,  respectively,  and $424.0  thousand and $604.0 thousand for the six

7.    All of our  wholly  and  partially  owned  businesses  operate  within the
      advertising,  marketing and corporate  communications  services  industry.
      These  agencies are organized  into  strategic  platforms,  client centric
      networks,  geographic regions and operating groups. Our businesses provide
      communications services to similar type clients on a global,  pan-regional
      and national basis. The businesses have similar cost  structures,  and are
      subject to the same general  economic and competitive  risks.  Given these
      similarities, we have aggregated their results into one reporting segment.

      bank  overdrafts of our  international  subsidiaries  which are treated as
      unsecured  loans  pursuant to our bank  agreements.  In January  2004,  in
      connection with the purchase of an office building,  we assumed a mortgage
      of $17.1 million which is included in our long-term debt.

            On May 24, 2004,  we amended and  extended  our  existing  revolving
      credit  facilities  with a consortium  of banks,  resulting in a five-year
      $1,500.0 million revolving credit facility which matures May 24, 2009, and
      a $500.0 million 364-day revolving credit facility with a maturity date of

      borrowings outstanding under these credit facilities. The 364-day facility
      includes a provision which allows us to convert all amounts outstanding at
      expiration  of the  facility  into a one-year  term loan.  The  consortium
      consists of 27 banks,  each  committing a pro rata amount to the five-year
      and 364-day  facilities.  Citibank N.A. acts as administrative  agent, ABN
      Amro acts as  syndication  agent and JPMorgan Chase Bank and HSBC Bank USA
      act as  co-documentation  agents  for the  facilities.  Other  significant
      lending institutions include Societe Generale,  Bank of America,  Wachovia
      and  Sumitomo  Mitsui.  These  facilities  provide us with the  ability to
      classify our  borrowings  that could come due within one year as long-term
      debt,  as it is our  intention  to keep the  borrowings  outstanding  on a
      long-term basis.

9.    Included in  operating  income for the six months ended June 30, 2004 is a
      pre-tax  net  gain of  $13.1  million  arising  from  investment  activity
      described below.

            In  March  2004,  in  connection  with  Seneca   Investments   LLC's
      ("Seneca") recapitalization, we agreed to exchange our remaining preferred
      stock  in  Seneca  for a $24.0  million  senior  secured  note  and 40% of
      Seneca's  outstanding  common stock. The note, which is due in March 2007,
      bears  interest  at  a  rate  of  6.25%  per  annum.   Prior  to  Seneca's
      recapitalization,  we were  accounting for our  investment  under the cost
      recovery method.  We will now account for this investment using the equity
      method.  The  recapitalization  transaction was required to be recorded at
      fair value and,  accordingly,  we  recorded  a net  pre-tax  gain of $24.0
      million.  This gain was  partially  offset by losses of $10.9  million  on
      other cost-based investments.

10.   The  following  pronouncement  was  issued  by  the  Financial  Accounting
      Standards Board ("FASB") in, or with effective  dates in, 2004:  Statement
      of Financial  Accounting  Standards No. 148,  Accounting  for  Stock-Based
      Compensation  - Transition  and  Disclosure - An Amendment of FASB No. 123
      (SFAS 148), which we adopted January 1, 2004, as discussed in Note 4.

            In March 2004, the FASB issued for exposure a Proposed  Statement of
      Financial  Accounting   Standards  entitled   "Share-Based  Payment  -  an
      amendment  of SFAS No. 123 and 95". The  proposal  requires  that the fair
      value of employee  stock-based  compensation  be  expensed.  Although  the
      proposal  differs from SFAS 123, as amended by SFAS 148, its  requirements
      will  only  apply to  newly  granted  stock or  options  to  employees  or
      previously  granted  awards  that are either  modified  or  settled  after
      January 1, 2004. We will continue

        NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued)

      to monitor the progress of the FASB with regard to the final  requirements
      of this new standard.

            The Emerging  Issues Task Force  ("EITF") of the FASB released issue
      No. 03-6,  "Participating  Securities and the Two-Class  Method under FASB
      Statement  No. 128,  Earnings  Per Share." EITF No. 03-6 is required to be
      adopted in  financial  periods  beginning  after March 31,  2004,  and the
      adoption  of EITF  No.  03-6 did not have an  impact  on our  consolidated
      results of operation or financial position.

            The following FASB  Interpretation  ("FIN") has an effective date in
      2004:  FIN  46,   Consolidation  of  Variable   Interest   Entities  -  An
      Interpretation of ARB No. 51, as amended by FIN 46R.

            FIN 46  addresses  the  consolidation  by  business  enterprises  of
      variable  interest  entities,  as  defined  in FIN 46, and is based on the
      concept that  companies that control  another  entity  through  interests,
      other than voting interests, should consolidate the controlled entity. The
      FASB  subsequently  issued FIN 46R in December 2003 that modified  certain
      provisions  of FIN 46.  FIN 46R must be  applied  to the  first  reporting
      period  after  March 15,  2004 and did not have an impact on, or result in
      additional disclosure in our financial statements.

11.   On July 29, 2004,  we offered to pay holders of our Zero Coupon Zero Yield
      Notes  due  2032,  $27.50  per  $1,000  principal  amount  of  notes as an
      incentive  to the holders who do not put their notes to us for  repurchase
      and who consent to certain  amendments  to the  indenture  under which the
      notes were issued. None of the notes were put to us for repurchase.  Under
      the amendments, we would pay cash, not stock as originally provided for in
      the indenture,  to noteholders for the initial  principal  amount of notes
      surrendered for conversion. The remainder of the conversion value would be
      paid in cash or shares, at our election. In addition,  the method by which
      contingent  cash interest is determined  will be amended.  Only consenting
      noteholders  will be  bound by the  amendments  to the  indenture.  If all
      noteholders  consent,  the total payment will be $24.5  million,  which we
      will amortize  ratably over the next 12 months.

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

Executive Summary

      We  are  a  holding  company  which  owns  industry-leading   advertising,
marketing  and  corporate  communications  companies  that  span  more  than  30
marketing  disciplines,  100  countries,  1,500  subsidiary  agencies  and 5,000
clients.  On a  global,  pan-regional  and local  basis,  our  agencies  provide
traditional media advertising  services as well as marketing  services including
customer relationship management, public relations and specialty communications.

      Given our size and breadth,  we manage the business by monitoring  several
financial and non-financial  performance indicators.  The key indicators that we
review focus on the areas of revenues and operating expenses.

      Revenue  growth is analyzed by  reviewing  the  components  and mix of the
growth,  including  growth  by major  geographic  location,  by major  marketing
discipline, from currency changes and from acquisition.

      Our revenue has historically  been derived almost evenly from our domestic
and  international  operations.  For the three months  ended June 30, 2004,  our
overall  revenue  growth  was  12.0%,  of which  3.5% was  related to changes in
foreign exchange rates and 2.5% was related to acquired entities.  The remainder
of our growth,  6.0%, was organic growth.  For the first six months of 2004, our
overall  revenue  growth  was  13.5%,  of which  5.0% was  related to changes in
foreign exchange rates and 2.6% was related to acquired entities.  The remainder
of our growth, 5.9%, was organic growth.

      For the three  months  ended June 30, 2004 and for the first six months of
2004,  traditional media advertising  represented about 44% of the total revenue
and grew by 12.3% and 13.1%,  respectively.  For the three months ended June 30,
2004 and in the first six months of 2004,  marketing services  represented about
56% of total revenue and grew by 11.8% and 13.9%, respectively.

      We measure operating expenses in two distinct cost categories:  salary and
service  costs,  and  office  and  general  expenses.  Because  we are a service
business,  we monitor these costs on a percentage of revenue basis. On an annual
basis, salary and service costs tend to fluctuate in conjunction with changes in
revenues, whereas office and general expenses, which are not directly related to
servicing  clients,  normally  tend to  decrease  as a  percentage  as  revenues
increase because a significant portion of these expenses are relatively fixed in
nature.  During the second quarter of 2004,  salary and service costs  increased
from 66.4% of revenue to 68.7% of revenue. Office and general expenses decreased
from 18.8% of revenue to 17.0% of revenue.  During the first six months of 2004,
salary and service  costs  increased  from 68.2% of revenue to 70.0% of revenue.
Office and general expenses decreased from 19.0% of revenue to 17.7% of revenue.

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

      Our net income for the second quarter of 2004 increased by 14.5% to $206.1
million from $180.0  million in the second  quarter of 2003, and our diluted EPS
increased by 14.6% to $1.10 from $0.96.  Our net income for the first six months
of 2004  increased by 15.6% to $341.7  million from $295.6  million in the first
six months of 2003, and our diluted EPS increased by 14.6% to $1.81 from $1.58.

      In   accordance   with  SFAS  No.   123,   "Accounting   for  Stock  Based
Compensation",   as  amended  by  SFAS  No.  148,  "Accounting  for  Stock-Based
Compensation  - Transition  and  Disclosure,  an amendment of FASB Statement No.
123", we elected to account for stock-based employee compensation using the fair
value  method  effective  January  1,  2004.  As a  result,  the  fair  value of
stock-based  employee  compensation,  including  unvested employee stock options
issued and  outstanding,  were  recorded  as an expense  in the  current  period
utilizing  the  retroactive  restatement  method  as  set  forth  in  SFAS  148.
Accordingly,  our results for the quarter ended June 30, 2003 and the six months
ended June 30, 2003 have been  restated as if we had used the fair value  method
to account for stock-based employee compensation. Results of pre-tax stock-based
employee  compensation  costs for the three  months ended June 30, 2004 and 2003
included $30.0 million and $32.4 million,  respectively,  and for the six months
ended  June  30,  2004  and 2003  included  $61.6  million  and  $67.1  million,
respectively.  Also, in connection with the  restatement,  the December 31, 2003
balance sheet  presented  above reflects an increase in the deferred tax benefit
of $120.5 million,  an increase in additional paid-in capital of $434.7 million,
an increase in unamortized stock compensation of $92.6 million and a decrease in
retained earnings of $221.6 million.

      The following analysis gives further  information about the changes in our
financial performance on a quarterly and six-month year-to-date basis.

Results of Operations:  Second Quarter 2004 Compared to Second Quarter 2003

      Revenue:  Our  second  quarter  of  2004  consolidated  worldwide  revenue
increased  12.0% to $2,407.8  million from  $2,149.5  million in the  comparable
period last year. The effect of foreign  exchange  impacts  increased  worldwide
revenue by $75.3 million.  Acquisitions,  net of disposals,  increased worldwide
revenue  by $54.7  million  in the second  quarter  of 2004 and  organic  growth
increased  worldwide  revenue by $128.3  million.  The  components of the second
quarter 2004 revenue  growth in the U.S.  ("domestic")  and the remainder of the
world ("international") are summarized below ($ in millions):

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
            $2,332.5  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 $2,407.8  million less  $2,332.5  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
            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 $2,149.5 million
            for the Total column in the table).

      The  components  of revenue and revenue  growth in our primary  geographic
markets for the second  quarter of 2004  compared to the second  quarter of 2003
are summarized below ($ in millions):

      As indicated, foreign exchange impacts increased our international revenue
by $75.3 million  during the quarter ended June 30, 2004.  The most  significant
impacts resulted from the continued period-over-period strengthening of the Euro
and the  British  Pound  against the U.S.  dollar,  as our  operations  in these
markets represented approximately 70.0% of our international revenue.

      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.

      Driven by our clients'  continuous demand for more effective and efficient
branding  activities,  we strive to provide an extensive  range of  advertising,
marketing and corporate  communications  services through various client-centric
networks that are organized to meet specific client  objectives.  These services
include   advertising,   brand  consultancy,   crisis   communications,   custom
publishing,  database  management,  digital and  interactive  marketing,  direct
marketing, directory advertising, entertainment marketing, environmental design,
experiential      marketing,      field      marketing,      financial/corporate
business-to-business   advertising,  graphic  arts,  healthcare  communications,
instore  design,  investor  relations,  marketing  research,  media planning and
buying,   multi-cultural   marketing,   non-profit   marketing,   organizational
communications, package design, product placement, promotional marketing, public
affairs,  public relations,  real estate advertising and marketing,  recruitment
communications,  reputation  consulting,  retail  marketing and sports and event
marketing.  In an effort to monitor  the  changing  needs of our  clients and to
further  expand the scope of our  services to key  clients,  we monitor  revenue
across a broad  range of  disciplines  and group  them into the  following  four
categories:  traditional media  advertising,  customer  relationship  management
(referred  to  as  CRM),  public  relations  and  specialty  communications,  as
summarized below.

      Salary and service costs,  which are comprised of direct service costs and
salary related costs,  increased by $226.9  million,  or 15.9%,  and represented
80.1% of total operating  expenses in the second quarter of 2004 versus 78.0% in
the second  quarter of 2003.  These  expenses also  increased as a percentage of
revenue to 68.7% in the second  quarter of 2004 from 66.4% in the second quarter
of 2003 primarily as a result of increased incentive  compensation costs as well
as increases in direct service costs,  including  increases in costs relating to
new business  initiatives and recruitment  costs,  and changes in the mix of our
revenues.  This was partially  offset by our  continued  efforts to increase the
variability of our cost structure on a location-by-location basis.

      Office and general  expenses,  which are comprised of office and equipment
rent, depreciation and amortization of other intangibles,  professional fees and
other  overhead  expenses,  increased by $7.0  million,  or 1.7%,  in the second
quarter of 2004 compared to the same period in 2003. Office and general expenses
decreased as a percentage of our total  operating costs in the second quarter of
2004 to 19.9% versus 22.0% in the prior period. Additionally, as a percentage of
revenue,  office and general expenses decreased in the second quarter of 2004 to
17.0% from 18.8% in the second quarter of 2003, as these expenses are relatively
fixed in nature and do not necessarily  change relative to our revenue growth or
changes in our salary and services costs.

      Net Interest  Expense:  Our net interest  expense in the second quarter of
2004 was $7.3 million,  down from $12.9 million in the same period in 2003.  The
decrease of $5.4 million in our gross interest expense was attributed to ratably
amortizing the $25.4 million  interest  payment made in February 2003 related to
our convertible  notes due 2031 over the 12-month period ended in February 2004.
No such payment was made in February 2004. In addition,  year-over-year interest
cost savings resulted from the issuance of $600.0 million  convertible  notes in
June  2003 at a zero  percent  interest  rate.  This  was  partially  offset  by
additional  amortization  expense related to the $6.7 million  interest  payment
made in August  2003  related to our  convertible  notes

due 2032.  Furthermore,  interest  expense  relative to the (euro)152.4  million
5.20%  Euro  note  increased  due to the  foreign  currency  change  of the Euro
relative to the U.S. dollar in the second quarter of 2004.

      On July 29, 2004,  we offered to pay holders of our Zero Coupon Zero Yield
Convertible  Notes due 2032  $27.50 per $1,000  principal  amount of notes as an
incentive to the holders which have not  exercised  their put right on August 2,
2004,  and who,  prior to the close of business  on August 9, 2004,  delivered a
consent to amend the indenture  under which the notes were issued.  We expect to
make a  $24.5  million  interest  payment  on  August  10,  2004,  or as soon as
practicably  possible,  and it will be amortized ratably over the next 12 months
and,  accordingly,  we expect interest expense to increase in the second half of
2004 compared to the first half of 2004.

      Income Taxes: Our consolidated  effective income tax rate was 33.6% in the
second  quarter of 2004,  which is consistent  with our full year rate for 2003,
but is less than the 33.9% rate in the second  quarter of 2003.  This  reduction
from the second quarter of 2003 reflects the realization of our ongoing focus on
tax  planning   initiatives,   including  increasing  the  efficiencies  of  our
international and state tax structures.

      Earnings Per Share (EPS): For the foregoing reasons, our net income in the
second quarter of 2004,  increased $26.1 million,  or by 14.5% to $206.1 million
from $180.0  million in the second quarter of 2003.  Diluted  earnings per share
increased  14.6% to $1.10 in the second quarter of 2004, as compared to $0.96 in
the prior year period.

Results of Operations:  First Six Months 2004 Compared to First Six Months 2003

      Revenue:  Our first  six  months of 2004  consolidated  worldwide  revenue
increased  13.5% to $4,639.2  million from  $4,086.8  million in the  comparable
period last year. The effect of foreign  exchange  impacts  increased  worldwide
revenue by $205.1 million.  Acquisitions,  net of disposals, increased worldwide
revenue by $106.9  million in the first six  months of 2004 and  organic  growth
increased  worldwide revenue by $240.4 million.  The components of the first six
months of 2004 revenue growth in the U.S.  ("domestic") and the remainder of the
world ("international") are summarized below ($ in millions):

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
            $4,434.1  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 $4,639.2  million less  $4,434.1  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
            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 $4,086.8 million
            for the Total column in the table).

      The  components  of revenue and revenue  growth in our primary  geographic
markets  for the first six  months of 2004  compared  to the first six months of
2003 are summarized below ($ in millions):

      As indicated, foreign exchange impacts increased our international revenue
by $205.1  million  during the first six months  ended June 30,  2004.  The most
significant impacts resulted from the continued period-over-period strengthening
of the Euro and the British Pound against the U.S. dollar,  as our operations in
these markets represented approximately 70.0% of our international revenue.

      In an effort to monitor the  changing  needs of our clients and to further
expand the scope of our services to key  clients,  we monitor  revenue  across a
broad range of disciplines  and group them into the following  four  categories:
traditional media advertising,  customer relationship management (referred to as
CRM), public relations and specialty communications, as summarized below.

        OF OPERATIONS  (Continued)

      Salary and service costs,  which are comprised of direct service costs and
salary related costs,  increased by $460.0  million,  or 16.5%,  and represented
79.9% of total  operating  expenses in the first six months of 2004 versus 78.2%
in the first six months of 2003.  These  expenses also increased as a percentage
of  revenue to 70.0% in the first six months of 2004 from 68.2% in the first six
months of 2003, primarily, as a result of increased incentive compensation costs
as well as  increases  in direct  service  costs,  including  increases in costs
relating to new business  initiatives and recruitment  costs, and changes in the
mix of our  revenues.  This was  partially  offset by our  continued  efforts to
increase the variability of our cost structure on a  location-by-location  basis
and the  positive  impact in the first  quarter  of 2004 of  previous  severance
actions.

      Office and general  expenses,  which are comprised of office and equipment
rent, depreciation and amortization of other intangibles,  professional fees and
other overhead expenses,  increased by $40.9 million,  or 5.3%, in the first six
months of 2004 compared to the same period in 2003.  Office and general expenses
decreased as a percentage of our total  operating  costs in the first six months
of 2004 to 20.1% versus 21.8% in the prior period. Additionally, as a percentage
of revenue,  office and general  expenses  decreased  in the first six months of
2004 to 17.7% from 19.0% in the first six months of 2003 as these  expenses  are
relatively fixed in nature and do not necessarily change relative to our revenue
growth or changes in our salary and service costs.

      Included  in office and general  expense  was a net gain of $13.1  million
related to  investment  activity  during the first  quarter.  In March 2004,  in
connection with Seneca's  recapitalization,  we agreed to exchange our remaining
preferred  stock in Seneca for a $24.0  million  senior  secured note and 40% of
Seneca's  outstanding  common stock. The note, which is due in March 2007, bears
interest  at a rate of 6.25% per annum.  The  recapitalization  transaction  was
required to be recorded  at fair value and,  accordingly,  we recorded a pre-tax
net gain of $24.0  million.  This gain was offset by losses of $10.9  million on
other cost-based investments.

      Excluding the net gain of $13.1 million,  office and general expenses were
17.9% of revenue in the first six months of 2004 compared to 19.0% of revenue in
the first six months of 2003 and operating  margin decreased to 12.1% of revenue
from 12.8% of revenue. This decrease in operating margin resulted primarily from
$9.9  million  of  costs  incurred  in  connection  with  the  disposal  of  two
non-strategic businesses.

      Net Interest Expense:  Our net interest expense in the first six months of
2004 was $17.7 million,  down from $21.2 million in the same period in 2003. Our
gross  interest  expense also  decreased by $2.9 million  which is attributed to
ratably  amortizing  the $25.4  million  interest  payment made in February 2003
related to our convertible notes due 2031 over the preceding twelve-month period
ended in February 2004. No such payment was made in February 2004. Interest cost
savings also resulted from the issuance of $600.0 million  convertible  notes in
June  2003 at a zero  percent  interest  rate.  This  was  partially  offset  by
additional  amortization  expense related to the $6.7 million  interest  payment
made in 2003 related to our  convertible  notes due 2032. In addition,  interest
expense relative to the (euro)152.4 million 5.20% Euro note increased due to the
foreign  currency  change of the Euro  relative to the U.S.  dollar in the first
half of 2004.

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

      Income Taxes: Our consolidated  effective income tax rate was 33.6% in the
first six months of 2004,  which is consistent with our full year rate for 2003,
but is less than the 34.2% rate in the first six months of 2003.  This reduction
from the first half of 2003 reflects the realization of our ongoing focus on tax
planning initiatives, including increasing the efficiencies of our international
and state tax structures.

      Earnings Per Share (EPS): For the foregoing reasons, our net income in the
first six months of 2004, increased $46.1 million, or by 15.6% to $341.7 million
from $295.6 million in the first six months of 2003.  Diluted earnings per share
increased  14.6% to $1.81 in the first six months of 2004,  as compared to $1.58
in the prior year period.

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

Critical Accounting Policies

      To assist in better understanding our financial statements and the related
management's discussion and analysis of those results, readers are encouraged to
consider  this  information   together  with  our  discussion  of  our  critical
accounting policies under the heading  "Management's  Discussion and Analysis of
Financial Condition and Results of Operations" in our Annual Report on Form 10-K
for the year ended  December  31,  2003 (the "2003 Form  10-K"),  as well as our
consolidated  financial  statements  and the related notes  included in our 2003
Form 10-K, for a more complete understanding of all of our accounting policies.

Proposed Accounting Pronouncements

      On June 30, 2004, the Emerging Issues Task Force ("EITF") of the Financial
Accounting  Standards Board ("FASB") reached a tentative  conclusion with regard
to  EITF  Issue  04-8,   Accounting   Issues  Related  to  Certain  Features  of
Contingently  Convertible  Debt and the Effect on Diluted Earnings per Share. As
currently drafted,  this tentative conclusion is expected to be finalized in the
Fall of 2004 and it would be  effective  beginning  with our  December  31, 2004
financials.  The tentative  conclusion  applies to all contingently  convertible
debt instruments including our Convertible Notes due 2031, 2032 and 2033.

      The tentative  conclusion  requires  companies to account for contingently
convertible  debt  using the "if  converted"  method set forth in  Statement  of
Financial  Accounting  Standard No. 128 for purposes of calculating diluted EPS.
Therefore,  contingently  convertible  debt would be included in the diluted EPS
calculation as if the debt had been converted into common stock.

      The  tentative  conclusion,  which  is  subject  to  change  before  it is
finalized,  requires  retroactive  application  and as a  result,  we  would  be
required  to restate  diluted EPS for prior  periods.  If adopted in its current
form, the application would result in a reduction of our diluted EPS.

Contingent Acquisition Obligations

      Certain of our  acquisitions  are structured  with  additional  contingent
purchase price obligations.  We utilize contingent  purchase price structures in
an effort to minimize the risk to us associated  with potential  future negative
changes in the  performance of the acquired  entity during the  post-acquisition
transition period. The amount of future contingent  purchase price payments that
we would be required to pay for prior  acquisitions,  assuming that the acquired
businesses  perform over the relevant  future  periods at their  current  profit
levels,  is approximately  $365 million as of June 30, 2004. The ultimate amount
payable cannot be predicted with  reasonable  certainty  because it is dependent
upon future  results of operations of subject  businesses and subject to changes
in foreign  currency  exchange  rates.  In  accordance  with  GAAP,  we have not
recorded a liability for these items on our balance  sheet since the  definitive


                                       19


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

amount is not  determinable  or  distributable.  Actual  results can differ from
these  estimates  and the actual  amounts that we pay are likely to be different
from these estimates.  Our obligations  change from period to period as a result
of payments made during the current period,  changes in the previous estimate of
the acquired entities'  performance,  changes in foreign currency exchange rates
and other  factors.  These  differences  could be  significant.  The  contingent
purchase  price  obligations as of June 30, 2004,  calculated  assuming that the
acquired  businesses  perform over the relevant  future periods at their current
profit levels, are as follows:

                               (Dollars in Millions)
       -------------------------------------------------------------------

      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 in those companies.  Assuming that the subsidiaries
and affiliates perform over the relevant periods at their current profit levels,
the  aggregate  amount  we  could  be  required  to pay  in  future  periods  is
approximately $253 million, $151 million of which relate to obligations that are
currently   exercisable.   The  ultimate   amount  payable   relating  to  these
transactions  will  vary  because  it is  dependent  on the  future  results  of
operations  of the  subject  businesses,  the  timing of the  exercise  of these
rights, changes in foreign currency exchange rates and other factors. The actual
amount  that we pay is  likely  to be  different  from  this  estimate,  and the
difference could be significant. The obligations that exist for these agreements
as of June 30, 2004, calculated using the assumptions above, are as follows:

                                             (Dollars in Millions)

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

If these  rights were  exercised,  there would  likely be an increase in our net
income  as a result of our  increased  ownership  and a  reduction  of  minority
interest expense.

Liquidity and Capital Resources

      Our principal non-discretionary funding requirement is our working capital
requirements.  In addition, we have contractual  obligations related to our debt
and convertible  notes, our recurring business  operations  primarily related to
lease obligations, as well as certain contingent acquisition obligations related
to acquisitions made in prior years.


                                       20


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

      Our principal discretionary cash requirements include dividend payments to
our   shareholders,   purchases  of  treasury  stock,   payments  for  strategic
acquisitions and capital expenditures.

      We have a seasonal working capital cycle. Working capital requirements are
lowest at year-end and higher  during the quarters.  This occurs  because in the
majority of our  businesses we act as agent on behalf of our clients,  including
when we place media and incur  production  costs on their  behalf.  We generally
require  collection  from our  clients  prior to our  payment  for the media and
production cost obligations and these obligations are greatest at the end of the
year.

      Historically,  on an annual basis, our discretionary and non-discretionary
spending has been funded from operating cash flow.  However,  during the year we
manage liquidity by utilizing our credit facilities discussed below.

      Liquidity:  We had cash and cash  equivalents  totaling $658.2 million and
$1,528.7 million at June 30, 2004 and December 31, 2003,  respectively.  We also
had  short-term  investments  totaling  $20.2  million at both June 30, 2004 and
December 31, 2003. Consistent with our historical trends in the first six months
of the year, we had negative cash flow from  operations  of $263.9  million.  We
funded this  deficit  primarily  with cash on hand and by  managing  our working
capital.

      Capital  Resources:  On May 24, 2004, we amended and extended our existing
revolving credit facilities with a consortium of banks, resulting in a five-year
$1,500.0  million  revolving  credit  facility which matures May 24, 2009, and a
$500.0 million 364-day revolving credit facility with a maturity date of May 23,
2005.  These  facilities  amended our previous  three-year,  $835.0  million and
$1,200  million,  364-day  revolving  credit  facilities.  We are also an active
participant in the commercial paper market with a $1,500.0 million program. Each
of our bank credit  facilities  provide credit support for issuances  under this
program.  As of June 30, 2004, no commercial paper was outstanding and we had no
other borrowings outstanding under these credit facilities. The 364-day facility
includes a  provision  which  allows us to convert all  amounts  outstanding  at
expiration of the facility into a one-year term loan. The consortium consists of
27 banks,  each  committing  a pro rata  amount  to the  five-year  and  364-day
facilities.  Citibank  N.A.  acts as  administrative  agent,  ABN  Amro  acts as
syndication   agent  and   JPMorgan   Chase  Bank  and  HSBC  Bank  USA  act  as
co-documentation   agents  for  the  facilities.   Other   significant   lending
institutions  include Societe Generale,  Bank of America,  Wachovia and Sumitomo
Mitsui.  These facilities provide us with the ability to classify our borrowings
that could come due within one year as long-term debt, as it is our intention to
keep the borrowings outstanding on a long-term basis.

      We had  short-term  bank loans of $41.4  million and $42.4 million at June
30, 2004 and December 31, 2003,  respectively,  which are  comprised of domestic
borrowings and bank overdrafts of our international subsidiaries and are treated
as unsecured loans pursuant to our bank agreements.


                                       21


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

      At June  30,  2004,  we also  had a total of  $2,339.3  million  aggregate
principal  amount of convertible  notes  outstanding,  including  $847.0 million
Liquid Yield Option Notes due 2031,  which were issued in February 2001,  $892.3
million Zero Coupon Zero Yield  Convertible Notes due 2032, which were issued in
March 2002,  and $600.0  million  Zero Coupon Zero Yield  Convertible  Notes due
2033, which were issued in June 2003.

      On July 29, 2004,  we offered to pay holders of our Zero Coupon Zero Yield
Notes due 2032,  $27.50 per $1,000  principal amount of notes as an incentive to
the holders who do not put their notes to us for  repurchase  and who consent to
certain  amendments to the indenture under which the notes were issued.  None of
the notes  were put to us for  repurchase.  Under the  amendments,  we would pay
cash, not stock as originally provided for in the indenture,  to noteholders for
the initial principal amount of notes surrendered for conversion.  The remainder
of the  conversion  value would be paid in cash or shares,  at our election.  In
addition,  the method by which  contingent  cash interest is determined  will be
amended.  Only  consenting  noteholders  will be bound by the  amendments to the
indenture.  If all noteholders consent, the total payment will be $24.5 million,
which we will amortize ratably over the next 12 months.

      At June 30, 2004, we had Euro-denominated bonds outstanding of (euro)152.4
million or $186.0  million.  The bonds pay a fixed rate of 5.2% to  maturity  in
June 2005.  While an increase in the value of the Euro  against the U.S.  dollar
will result in a greater  liability for interest and principal,  there will be a
corresponding increase in the dollar value of our Euro-denominated net assets.

      Our outstanding  debt and amounts  available under these  facilities as of
June 30, 2004 ($ in millions) were as follows:



                                                                                        Debt           Available

      We believe that our operating cash flow combined with our available  lines
of credit and our access to the capital  markets are  sufficient  to support our
foreseeable cash requirements,  including working capital, capital expenditures,
dividends and acquisitions.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

      Our results of operations are subject to risk from the  translation to the
U.S.  dollar of the revenue and  expenses of our foreign  operations,  which are
generally denominated in the local currency. For the most part, our revenues and
the expenses  incurred  related to those  revenues are  denominated  in the same
currency.  This  minimizes the impact that  fluctuations  in exchange rates will
have on profit margins.

      Our 2003 Annual Report on Form 10-K for the year ended  December 31, 2003,
provides  a  more  detailed   discussion  of  the  market  risks  affecting  our
operations.  As of June 30, 2004, no material  change had occurred in our market
risks from the disclosure contained in that 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 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
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, and those differences could be material.


                                       23


ITEM 4. CONTROLS AND PROCEDURES

      We maintain  disclosure  controls and  procedures  designed to ensure that
information  required to be included in our SEC reports is recorded,  processed,
summarized,  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  were  effective  to  ensure   recording,
processing,  summarizing,  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 materially  affect the  effectiveness  of these  controls since that
evaluation was completed.
