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,  although the
     Company  believes that the disclosures are adequate to make the information
     presented not misleading.

2)     These statements reflect all  adjustments, consisting of normal recurring
     accruals  which,  in the opinion of  management,  are  necessary for a fair
     presentation    of   the    information    contained    therein.    Certain
     reclassifications have been made to the September 30, 1995 reported amounts
     to  conform  them  with the  September  30,  1996  and  December  31,  1995
     presentation.  It is suggested that these consolidated  condensed financial
     statements  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, 1995.

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

4)     Primary earnings per share is based upon the weighted  average  number of
     common shares and common share equivalents  outstanding during each period.
     Fully  diluted  earnings per share is based on the above,  and if dilutive,
     adjusted  for  the  assumed   conversion  of  the   Company's   Convertible
     Subordinated  Debentures  and the  assumed  increase  in net income for the
     after tax interest cost of these debentures.

       The  number of  shares  used in the  computations  of  primary  and fully
     diluted earnings per share were as follows:

     interests,   effective   January  1,   1996.   The   assets,   liabilities,
     shareholders'  equity and results of operations of Ketchum are not material
     to the Company, and therefore the Company's prior year financial statements
     were not restated.

Results of Operations

Third Quarter 1996 Compared To Third Quarter 1995

     Consolidated  worldwide  revenues from commission and fee income  increased
17.5% in the  third  quarter  of 1996  compared  to the third  quarter  of 1995.
Consolidated  domestic revenues  increased 25.4% in the third quarter of 1996 to
$341.6  million  compared  to  $272.3  million  in the  third  quarter  of 1995.
Consolidated  international revenues increased 9.3% in the third quarter of 1996
to $290.2  million  compared  to $265.4  million  in the third  quarter of 1995.
Absent the effect of the net acquisitions of subsidiary  companies and movements
in  international  currency  exchange  rates,  consolidated  worldwide  revenues
increased  13.5% in the third  quarter of 1996 as compared to the same period in
1995.

     Operating expenses increased 16.3% in the third quarter of 1996 as compared
to the third  quarter  of 1995.  Excluding  the  effect  of the net  acquisition
activity and movements in international currency exchange rates mentioned above,
operating  expenses  increased  12.1% over 1995 levels.  This increase  reflects
normal salary increases and growth in client service expenditures to support the
increased revenue base.

                                      -8-



                 MANAGEMENT'S DISCUSSION OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS (CONTINUED)
- --------------------------------------------------------------------------------

     Net interest expense decreased by $2.7 million in the third quarter of 1996
as compared to the same period in 1995. This decrease  primarily  reflects lower
average  interest  rates  on  borrowings  and  the  conversion  of  the  Step-Up
Convertible Subordinated Debentures.

     Pretax  profit  margin was 8.7% in the third quarter of 1996 as compared to
7.2% in the same period in 1995.  Operating margin,  which excludes interest and
dividend income and interest  expense,  was 9.4% in the third quarter of 1996 as
compared to 8.5% in the same period in 1995.

     The  effective  income  tax rate of 40.3% in the third  quarter of 1996 was
comparable  to the  effective  income tax rate of 40.0% in the third  quarter of
1995.

     The decrease in equity in affiliates is primarily due to the  conversion of
certain  affiliates into  partnerships  or  subsidiaries  and the disposal of an
affiliate during the prior quarter,  partially offset by the effect of increased
earnings at the Company's equity  affiliates.  The increase in minority interest
expense is  primarily  due to  greater  earnings  by  companies  where  minority
interests exist and additional  minority interests  resulting from acquisitions,
partially  offset by the  acquisition  of  certain  interests  held by  minority
shareholders during the period.

                 MANAGEMENT'S DISCUSSION OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS (CONTINUED)
- --------------------------------------------------------------------------------

     Net income  increased 36.1% in the third quarter of 1996 as compared to the
same period in 1995.  Absent the effect of net  acquisitions  and  movements  in
international  currency  exchange rates, net income increased 31.6% in the third
quarter of 1996 as compared to the third quarter of 1995.

Nine Months 1996 Compared to Nine Months 1995

     Consolidated  worldwide  commission and fee income  increased  17.6% in the
first  nine  months  of  1996  compared  to  the  first  nine  months  of  1995.
Consolidated  domestic  commission and fee income  increased  25.3% in the first
nine months of 1996 to $1,017.8  million  compared to $812.1 million in the same
period in 1995. Consolidated  international  commission and fee income increased
9.7% in the  first  nine  months of 1996 to $872.0  million  compared  to $794.9
million  in the  same  period  in  1995.  Absent  the  effect  of  movements  in
international  currency  exchange  rates  and  net  acquisitions  of  subsidiary
companies made subsequent to the third quarter of 1995,  consolidated  worldwide
commission  and fee  income  increased  13.4% in the first  nine  months of 1996
versus the first nine months of 1995.

     Operating  expenses  increased by 17.1% in the first nine months of 1996 as
compared  to the same  period in 1995.  Excluding  the  effect of  movements  in
international  currency exchange rates and net acquisition  activity,  operating
expenses increased 12.4% over 1995 levels.

                 MANAGEMENT'S DISCUSSION OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS (CONTINUED)
- --------------------------------------------------------------------------------

     Net interest expense  decreased by $6.5 million in the first nine months of
1996 as compared to the same period in 1995.  This decrease  primarily  reflects
lower average  interest  rates on borrowings  and the  conversion of the Step-Up
Convertible Subordinated Debentures.

     Pretax  profit  margin  for the  first  nine  months  of 1996 was  10.9% as
compared to 10.0% in the same period in 1995.  Operating margin,  which excludes
interest and dividend income and interest  expense,  was 11.7% in the first nine
months of 1996 as compared to 11.4% in the same period in 1995.

     The effective income tax rate of 40.4% in the first nine months of 1996 was
comparable to the effective income tax rate of 40.5% in the first nine months of
1995.

     The decrease in equity in affiliates is primarily due to the  conversion of
certain  affiliates into  partnerships  or  subsidiaries  and the disposal of an
affiliate  during  the  period,  partially  offset by the  effect  of  increased
earnings at the Company's affiliates.  The increase in minority interest expense
is primarily due to greater earnings by companies where minority interests exist
and additional minority interests resulting from acquisitions,  partially offset
by the acquisition of certain interests held by minority shareholders during the
period.

     Net income  increased 25.7% in the first nine months of 1996 as compared to
the same period in 1995.  Absent the effect of net acquisitions and movements in
international  currency  exchange rates, net income increased 22.5% in the first
nine months of 1996 as compared to the same period in 1995.

Capital Resources and Liquidity

     Cash and cash equivalents at September 30, 1996 decreased to $191.0 million
from $314.0 million at December 31, 1995. The  relationship  between payables to
the media and suppliers and receivables from clients,  at September 30, 1996, is
consistent with industry norms.

     The Company maintains relationships with a number of banks worldwide, which
have extended unsecured  committed lines of credit in amounts sufficient to meet
the Company's cash needs.  At September 30, 1996, the Company had $516.8 million
in such  unsecured  committed  lines of credit,  comprised  of a $360.0  million
revolving credit  agreement  expiring June 30, 2001, and $156.8 million in lines
of credit,  principally  outside of the United States.  Of the $516.8 million in
unsecured  committed lines,  $254.1 million remained  available at September 30,
1996.

     Management  believes the aggregate lines of credit available to the Company
plus cash flows from  operations  will be adequate  to support  its  anticipated
requirements.

     On March 1, 1996,  the Company  issued  Deutsche Mark 100 million  Floating
Rate  Bonds(approximately  $68 million at the March 1, 1996 exchange rate).  The
bonds are unsecured, unsubordinated obligations of the Company and bear interest
at a per annum rate equal to Deutsche  Mark three month LIBOR plus  0.375%.  The
bonds will mature on March 1, 1999 and will be repaid at par.

     On July 12, 1996, the Company  announced the redemption of its  outstanding
4.5% /  6.25%  Step-up  Convertible  Subordinated  Debentures  with a  scheduled
maturity in 2000. On or before the September 5, 1996 redemption date,  debenture
holders elected to convert all of their outstanding debentures into common stock
of the Company.  To complete the  redemption,  5,238,678  shares of common stock
were issued at a conversion price of $27.44 per share.
