Employer  without Cause,  the period of time  immediately  prior to September 1,
1986 during which the Participant was in the continuous employ of members of the
Employer Group shall be taken into


                                      -4-

      expiration date of the authorized leave of absence; and

            (ii) time spent in the  service of others at the request of, or with

                                      -5-


III. Employment Is Unrestricted.

      Nothing herein contained shall be deemed to give the Participant the right
to remain in the employ of the  Employer or to  interfere  with the right of the
Employer to terminate the Participant's  employment at any time, nor to give the
Employer  the right to  require  the  Participant  to remain in its employ or to
interfere with the Participant's right to terminate employment at any time.

IV. Compensation.

      1. In the  event  (a) the  Participant  dies  while in the  employ  of the
Employer.  (b) the  Employer  determines,  in the manner  provided in Article 1,
Section 14 hereof,  that the  Participant  is disabled and the employment of the
Participant  is  terminated  by the  Employer by reason of  Disability,  (c) the
Participant, after 5 Years of Service, terminates his or her employment with the
Employer  for a reason  other than to enter the employ of another  member of the
Employer  Group or (d) the  employment of the  Participant  is terminated by the
Employer  for a reason  other than Cause,  then upon the  happening  of any such
event the Company,  subject to all the terms and conditions hereof, shall become
obligated to pay to the  Participant,  or to the  Beneficiary  if the obligation
arises under (a) above, each year, for the number of consecutive  calendar years
determined in accordance with the schedule on page 7 hereof,  an amount equal to
the lesser of (i) the Salary  Limitation  applied to one year's salary,  or (ii)
the  Participation  applied to the net profits of the  Company for the  calendar
year immediately  preceding the calendar year of payment,  subject to adjustment
as provided in Sections 2, 3 and 4 of this Article.

      2. If the  employment  of the  Participant  is  terminated by reason of an
event occurring under (c) of Section 1 of this Article and at the effective date
of such termination the Participant has not accumulated 20 Years of Service, the
annual  payment the  Participant  would have been entitled to receive under said
Section 1  ("Proposed  Payment")  shall be reduced to an amount  resulting  from
multiplying  the Proposed  Payment by a fraction  the  numerator of which is the
Participant's Years of Service at the effective date of such termination and the
denominator of which is 20. The Committee may, in its absolute discretion, waive
this  provision or reduce the number of the  denominator  in said fraction if it
decides such action would be in the best  interest of the Company and  equitable
to the Participant or the Beneficiary.


                                      -6-


      3.(a) In the event of the  Participant's  death after the occurrence of an
event  described  in (b), (c) or (d) of Section 1 of this Article and before the
Participant  has received  payment(s) in respect of the total number of calendar
years as to which the Company is obligated to make payment  hereunder  ("Payment
Period"), the Company shall thereafter be obligated to make an annual payment to
the Beneficiary during the Payment Period or the remainder thereof,  as the case
may be,  equal to seventy  five (75%)  percent of the amount  which the  Company
would have been obligated to pay to the Participant had the Participant lived to
receive all payments.

      (b) In the event of the  Participant's  death  while in the  employ of the
Employer,  the  Company  shall be  obligated  to make an annual  payment  to the
Beneficiary in the same manner and to the same extent as provided in (a) of this
Section 2.

      4. If during any period of  twenty-four  consecutive  months assets of the
Company are sold or otherwise  disposed of having a value or aggregate  value of
thirty  (30%)  percent  or more of the  total  assets of the  Company  as at the
commencement date of said period ("Disposal  Transaction"),  then beginning with
the  calendar  year in which the Disposal  Transaction  occurs the amount of the
annual  payments the Company may be obligated  to make under the  provisions  of
Section 1 of this Article shall be the Salary  Limitation  applied to one year's
salary. If the asset sold or disposed of is stock of a Subsidiary,  the value of
the total assets,  not net assets,  of the Subsidiary shall be used for purposes
of this Section 4.

      5. The  first  calendar  year of  payment,  if any,  shall  be the  second
calendar  year  following the calendar year in which the event that gave rise to
the Company's obligation to pay occurred.  If, however,  such event is the death
of the Participant while in the employ of the Employer,  the first calendar year
of payment shall be the first calendar year following the calendar year in which
the Participant's  death occurred.  Payment shall be made by the Company in each
calendar  year of  payment  during  the first  ninety  (90) days of the  subject
calendar year.

      6. The amount  payable  hereunder by the Company in respect of the Payment
Period  shall  be  reduced  by the  value  of  pension,  deferred  compensation,
retirement  and  like  payments  ("Retirement  Payments")  to be made  following
cessation of Participant's  employment to the Participant,  Beneficiary or other
designee of the Participant  pursuant to an agreement or arrangement between the
Participant and one or more members of the Employer Group.  For purposes hereof,
Retirement  Payments shall not include payments under a pension,  profit-sharing
or savings plan which  qualifies for  favorable  tax treatment  under the United
States Internal Revenue Code, payments under an agreement financed solely by the
Participant,  and payments under an agreement which becomes  operative by reason
of a change in control of the Company (golden  parachute  agreement),  but shall
include payments  described in paragraph 4 of the Employment  Agreement  between
DDB Needham Worldwide Inc. and the Participant made on September 1, 1984, a copy
of the text of which is attached hereto as Exhibit A.

business  as that of the  Employer;  and the  Participant  shall  not  make  any
financial  investment,  direct or indirect, in any sole proprietorship or entity

herein  shall  prohibit  the  purchase  of less than a  controlling  interest in
publicly traded securities of any such entity for bona fide investment only;

      (b) that the Participant  shall not willfully engage in any activity which

shall be entitled to be present, and the determination by the Board of Directors
shall be final and conclusive; and

      (c) Nothing herein prohibits or restricts the Participant from engaging in
Protected  Easiness in the related  areas  described  in  Subsection  (a) above,
making a Protected  Investment,  or wilfully engaging in activity harmful to the
interest  of the  Company  (collectively  "Activities"),  and in the  event  the
Participant chooses to engage in any of such Activities the Company's obligation
to make payments hereunder shall forthwith  terminate as to payments which might
otherwise have become payable to the Participant in respect of the calendar year
in which such Activity occurred and to the Participant or the Beneficiary in


                                      -9-


respect of all  calendar  years  thereafter,  but the  Participant  shall not be
obligated to refund to the Company any payments  theretofore paid to Participant
hereunder. If requested in writing by the Company, the Participant shall, within
30 days after receipt of such request, advise the Company in writing whether the
Participant has or has not engaged in such  Activities for a specified  calendar
year,  and the Company  shall have no obligation to make a payment in respect of
such calendar  year until the Company has received such written  advice from the
Participant.

      VI. Company's Payment Obligation Conditional On Participant's Availability
for Advisory and Consultative Services after Severance of Employment.

      (a) It is a further condition of the Company's obligation to make payments
hereunder that from the date of the occurrence of an event described in (b), (c)
or (d) of  Section 1 of  Article  IV hereof  that  shall  have given rise to the
obligation  to pay and until the close of the last  calendar  year in respect of
which the Participant may become entitled to receive  payments  hereunder,  that
the  Participant,   if  not  physically  or  mentally  disabled,  shall,  as  an
independent  contractor  and upon not less than thirty  (30) days prior  written
notice from the Company,  make his or her services  available to the Company for
such  periods of time as may be  specified  in the  notice,  as an  advisor  and
consultant  with  respect  to  activities  of  the  department  or  unit  of the
Employer's  business  to which  the  Participant  was last  assigned,  provided,
however, that the Participant shall not be obligated to make his or her services
available  (i) for more than sixty (60) days in the  aggregate and for more than
twenty  (20)  consecutive  days in any one  calendar  year,  and (ii) during the
period  December  15  through  January  15.  The  Company  shall  reimburse  the
Participant  for  reasonable  traveling,   transportation  and  living  expenses
necessarily incurred by the Participant while away from his or her regular place
of residence in the performance of such advisory and  consultative  services for
the Company.

      (b) In the event  the  Participant  chooses  not to  render  advisory  and
consultative  services  when  requested by the Company as provided in Subsection
(a) above, the Company's  obligation to make payments  hereunder shall forthwith
terminate  as to payments  which  might  otherwise  have  become  payable to the
Participant  in respect of the calendar year in which such event occurred and to
the Participant or the Beneficiary in respect of all calendar years  thereafter,
but the Participant shall not be obligated to refund to the Company any payments
theretofore paid to Participant hereunder.


                                      -10-


VII. Prepayments.

      Following the occurrence of an event  described in Section I of Article IV
hereof,  the Company may, at any time and from time to time,  make a prepayment,
in whole or in part, of its  obligation  hereunder in respect of any one or more
calendar years and any such prepayment shall be irrevocable and non-refundable.

VIII. Participant's   and   Beneficiary's   Rights   Hereunder   Are   Personal,
      Nonassignable and Nontransferable.

      1.  The  right of the  Participant  or  Beneficiary  to  receive  payments
hereunder is personal,  non-assignable and  non-transferable by operation of law
or otherwise.  The word  "otherwise"  in the preceding  sentence  shall include,
without limitation, any execution,  levy, garnishment,  attachment or seizure by
any other legal process.

      2. If at the time the Company is to make a payment to the Participant or a
Beneficiary  hereunder the Participant or Beneficiary is not entitled to receive
such payment by reason of  non-compliance  with the  provisions  of Section 1 of
this Article, the obligation of the Company to make such payment shall forthwith
terminate.

IX. Designation and Identity of Beneficiary.

      1. The  Participant  may  designate a Beneficiary  by signing,  dating and
filing with the Secretary of the Company a written  instrument setting forth the
name(s) and address(es) of the Beneficiary,  and if the Beneficiary be more than
one person or entity,  describing  the  allocation of the payment  benefit among
them. The  Participant  may change his or her  designation of a Beneficiary  and
thereby revoke a prior designation of a Beneficiary at any time and from time to
time by filing a new such written instrument with the Secretary. The Beneficiary
named  in  the  last  unrevoked  designation  of  Beneficiary  so  filed  by the
Participant  prior to his or her death shall be the  Beneficiary for purposes of
this  Agreement.  In  the  absence  of  a  designation  of  Beneficiary  by  the
Participant, or in the event the last written designation of Beneficiary on file
with the Secretary has been revoked by the Participant, the Beneficiary shall be
as described in Section 8 of Article. I of this Agreement.

      2. It is a condition of the  Company's  obligation to make payments to the
Beneficiary  hereunder that (a) in making  payments the Company may, in its sole
and absolute discretion,  rely upon signed, written declarations,  verifying the
identity of a Beneficiary filed with the Secretary of the Company by a person or
entity claiming to be such  Beneficiary;  (b) any payment made by the Company in
good faith to any claimant, whether or not such


                                      -11-


declarations shall have been filed with the Company,  shall pro tanto, discharge
any obligation the Company might  otherwise have to make payments to any and all
other  actual or  possible  claimants;  (c) any person or entity  claiming to be
entitled to receive  payments  hereunder  following the death of the Participant
shall have  recourse only against the person or entity to whom the Company shall
have made payment in good faith; and (d) in the event the Company,  on advice of
counsel, delays payment of any sums becoming due to a Beneficiary by reason of a
dispute as to the  legitimacy  of the claim of such  Beneficiary,  no  interest,
penalty or damage shall  accrue,  become  payable by or be assessed  against the
Company by reason of such delay in payment.

X. Payment to Minors.

      Any  payment  to be made  by the  Company  to a  person  under  the age of
twenty-one  (21)  years  may be made  to such  person  or to a  guardian  of the
property of such person or to a parent of such person as the Company may, in its
sole and  absolute  discretion,  determine.  As to any payment  becoming  due or
payable to a person  under the age of  twenty-one  (21)  years,  the Company may
defer such payment until the Company has received  notice of the appointment and
qualification  of a guardian of the  property of such  person,  and no interest,
penalty or damage shall  accrue,  become  payable by or be assessed  against the
Company by reason of such delay in payment.

XI. Miscellaneous Provisions.

      1. An act or determination by the Board of Directors of the Company or the
Employer may be made by a committee of directors, numbering not less than three,
appointed by the Board for such purpose.

      2. Notices shall be sent by registered or certified  mail,  return receipt
requested, to the Participant at the Participant's last address on file with his
or her Employer or to such other  address as may  hereafter be designated by the
Participant to the Company,  and to the Beneficiary at the address listed in the
latest  written  designation  of  beneficiary  filed  with  the  Company  by the
Participant  or to such other  address as may  hereafter  be  designated  by the
Beneficiary to the Company subsequent to the death of the Participant.

      3. The failure of any party to insist upon strict adherence to any term of
this  Agreement  on any occasion  shall not be  considered a waiver of any right
hereunder,  nor shall it deprive  that party of the right  thereafter  to insist
upon  strict  adherence  to that term or any other term of this  Agreement.  Any
waiver must be in writing.


                                      -12-


      4. This  Agreement sets forth the entire  understanding  of the parties in
respect of the subject matter hereof, superseding, and evidencing and confirming
the termination of, any and all prior agreements, arrangements or understandings
between  the parties  relating to such  subject  matter,  and neither  party has
relied on any  representations  of the other party except as expressly set forth
herein.  This Agreement may be amended only by a written  instrument  signed by
both parties.

      5. This Agreement  shall be construed and  interpreted in accordance  with
the laws of the State of New York,  and is  subject to all  applicable  federal,
state and municipal laws and regulations now or hereafter in force.

      IN WITNESS  WHEREOF,  the parties hereto have duly executed this Agreement
as of the date first above written.

                                    EXHIBIT A

4.    Retirement Benefit.

(a)   Retirement Income.

      (i)   When EXECUTIVE ceases to be in the employ of the Company, whether at
            or subsequent to the expiration of the employment period, other than
            by reason of termination of his employment by the Company for cause,
            the Company shall pay EXECUTIVE  retirement income at an annual rate
            equal  to  the  greater  of  (1)  sixty-six   thousand  six  hundred
            sixty-seven  dollars  ($66,667) or (ii)  thirty-three  and one-third
            percent (33 1/3%) of the weighted  average annual salary  (excluding
            bonuses and other benefits) paid by the Company to EXECUTIVE  during
            the last sixty (60) months of his  employment  by the  Company.  For
            purposes of this  paragraph 4, the rate of annual salary paid by the
            Company to EXECUTIVE during the employment period shall be deemed to
            be not less  than  Six  Hundred  Thousand  Dollars  ($600,000).  The
            retirement   income,  as  thus  calculated,   shall  be  subject  to
            cost-of-living adjustments as set forth below. The retirement income
            provided for hereby shall be payable monthly, beginning in the month
            following  the  month  during  which  EXECUTIVE  ceases to be in the
            employ of the Company or during which  payments,  if any, being made
            to the EXECUTIVE under paragraph 2(c) hereof terminate, whichever is
            the last to occur, and continuing for ten (10) years.

      (ii)  As of each anniversary of the date retirement  income payments begin
            under  paragraph  4(a)(i)  ("Adjustment  Date"),  the  amount of the
            retirement income payments to be made pursuant to paragraph 4(a)(i)


                                      -5-

            shall be increased or decreased, as the case may be be, by an amount
            equal to the amount of  retirement  income  determined  pursuant  to
            paragraph  4(a)(i)  (without regard to the  adjustments  provided in
            this paragraph 4(a)(ii) multiplied by the Cost-Of-Living  Change, as
            defined below, provided that the incremental increase or decrease in
            such  payments  as of the then  current  Adjustment  Date  shall not
            exceed ten  percent  (10%) of the  retirement  income  that would be
            payable  (without  regard to the  proviso  set  forth  below) if the
            Current Cost-Of-Living Index remained unchanged from the immediately
            preceding  year;  provided,  however,  that  if  any  portion  of an
            increase or decrease that would  otherwise  apply on any  Adjustment
            Date cannot be made  effective  because of the foregoing ten percent
            (10%) limitation,  such portion of the increase or decrease shall be
            applied  on   immediately   succeeding   Adjustment   Dates   (after
            calculation of the amount  otherwise due as of such  Adjustment Date
            and to the extent such  application  will not result in an aggregate
            increase or decrease that exceeds the  applicable  ten percent (10%)
            limit)  until such amount is exhausted  (or the period  during which
            payments  are to be made ends).  For the  purpose of this  paragraph
            4(a)(ii):

            (A) the "Current  Cost-Of-Living  Index" as of any  Adjustment  Date
            shall be the monthly  National  Consumer  Price Index figure for the
            month next  preceding  the  Adjustment  Date issued by the Bureau of
            Labor Statistics of the United States Department of Labor;

            (B) the "Base Cost-Of-Living  Index" shall mean the monthly National
            Consumer  Price Index figure issued for the month next preceding the
            month as of which  retirement  income  payments begin as provided in
            the last sentence of paragraph 4(a)(i) above;



                                      -6-

            (C) the "Cost-Of-Living Change" as of any Adjustment Date shall be a
            fraction whose  numerator is an amount equal to the Current  Cost-Of
            Living  Index  minus  the  Base   Cost-Of-Living   Index  and  whose
            denominator Is the Base Cost-Of-Living Index.


      Should the method of  determining  the  Monthly  Consumer  Price  Index be
      revised by the Bureau of Labor Statistics,  such revisions as the Board of
      Directors of the Company shall  determine to be appropriate  and equitable
      shall  be made in the  calculation  of the  Current  Cost-of-Living  Index
      hereunder.


(b) Breach by Executive.

      (i)   EXECUTIVE may engage in the advertising agency business, as an owner
            or  employee  of  another  advertising  agency,  at a time  when the
            Company  is  obligated  to pay  retirement  income to the  EXECUTIVE
            pursuant  to  paragraph  4(a)(i)  so long as  such  activity  is not
            inconsistent  with  the  covenants  of the  EXECUTIVE  set  forth in
            paragraph 4(b)(ii) below. In the event that the EXECUTIVE engages in
            the  advertising  agency  business as  permitted  in this  paragraph
            4(b)(ii),  the obligation of the Company to pay  retirement  income,
            and the  obligation  of the  EXECUTIVE  to  render  services  to the
            Company under  paragraph 4(c), will be suspended until the EXECUTIVE
            ceases to be so engaged in the advertising  agency business or dies,
            at which time such  obligations  of the Company and of the EXECUTIVE
            (if he is  living)  will be  reinstated.  The ten (10)  year  period
            referred to in paragraph  4(a)(i) shall be extended by the period of
            any such  suspension.  If the EXECUTIVE shall again so engage in the
            advertising  agency  business,  the obligations of the parties shall
            again be suspended and subsequently reinstated in the same manner.



                                      -7-

      (ii)  During the period EXECUTIVE is entitled to receive retirement income
            as provided in paragraph  4(a)(i)("Entitlement  Period"), and during
            the  period,  if any,  that the  obligations  of the  Company to pay
            retirement  income is  suspended  as provided in  paragraph  4(b)(i)
            ("Suspension Period"), the EXECUTIVE covenants and agrees that:

            (A) during the  Entitlement  Period  and the  Suspension  Period the
            EXECUTIVE will not,  directly or indirectly,  persuade or attempt to
            persuade any client of the Company or any  subsidiary to discontinue
            in whole or in part  any  service  rendered  by the  Company  or any
            subsidiary to such client;

            (B)  during  the  first  year  of  the  Entitlement  Period  or  the
            Suspension  Period,  whichever first occurs,  the EXECUTIVE will not
            render services,  in behalf of any other advertising  agency, to any
            client of the Company or any  subsidiary  or to any former client of
            the Company or any subsidiary,  unless such former client shall have
            ceased to be a client of the Company or such subsidiary at least one
            (1) year  before the  EXECUTIVE  became  associated  with such other
            advertising agency; and

            (C)  during  the  first  year  of  the  Entitlement  Period  or  the
            Suspension  Period,  whichever first occurs,  the EXECUTIVE will not
            furnish any  services to or for any  company or  advertising  agency
            with  respect to any  product or  services  which are  identical  or
            competitive with any product  serviced or services  furnished by the
            Company or any  subsidiary  at the time or within one (1) year prior
            to the commencement of the applicable period.



                                      -8-

      Products  will be deemed  competitive  if they can be used for the same or
      similar purposes.  Without limiting any other remedy which the Company nay
      have in law or in equity,  in the event of the breach of this  covenant by
      the  EXECUTIVE,  the  Company  may  discontinue  the inking of any and all
      payments provided for in paragraph 4(a)(i).

(c) Consulting Agreement.

      (i)   The  EXECUTIVE  agrees that at all times during which he is entitled
            to receive  retirement  income pursuant to paragraph 4(a)(i) he will
            take himself  available in an advisory  and  consulting  capacity to
            render general advice and consultation.

      (ii)  With respect to the advisory and consulting  services referred to in
            paragraph  4(c)(i) above,  (A) it is anticipated  that the EXECUTIVE
            normally  will not devote to the  performance  of such services more
            than  five  (5)  business  days  in any  month  during  which  he is
            obligated to render such  advisory or consulting  services;  (B) the
            Company will consider the reasonable convenience of the EXECUTIVE in
            the timing of its  requests to perform  such  services and will give
            the  EXECUTIVE  as much  advance  notice of such  requests as may be
            practicable;  (C) this agreement on the part of the EXECUTIVE is not
            intended to subordinate the EXECUTIVE's  other  activities,  whether
            personal,  business or otherwise,  to those of the Company, it being
            understood  that the EXECUTIVE shall be free to arrange his own time
            and pursuits  and to perform  such  services in manners and at times
            and places of his own choosing;  and (D) the  EXECUTIVE  will not be
            obligated  to render  such  advisory  or  consulting  services  with
            respect to matters in which the  interests  of any  business,  other
            than the  advertising  agency  business,  in which the  EXECUTIVE is
            engaging as an owner or employee, are incompatible with those of the
            Company.



                                      -9-

      (iii) After the date upon which the EXECUTIVE attains age sixty-five (65),
            or in the event he becomes  disabled  at any time in the  opinion of
            competent medical authority, he will not be obligated to perform the
            consulting and advisory services provided for in paragraph  4(c)(i).
            In any such event,  the EXECUTIVE  shall  continue to be entitled to
            receive the retirement income provided for by paragraph 4(a)(1).  In
            the event EXECUTIVE  breaches the provisions of this paragraph 4(c),
            the Company may discontinue the making of any payments  provided for
            in paragraph 4(a)(i) in respect of the period of the breach.

(d) Death of EXECUTIVE.

      (i)   In the event  the  EXECUTIVE  shall  die while in the  employ of the
            Company,  the retirement  income payments will be made in accordance
            with   paragraph   4(a)(i)  as  though  the  ten  (10)  year  period
            contemplated  therein  had  commenced  on the first day of the month
            following the date of his death.

      (ii)  In the event the EXECUTIVE shall die during the  Entitlement  Period
            or the Suspension  Period,  the retirement  income payments provided
            for by paragraph  4(a)(i) will  continue for the reminder of the ten
            (10) year period contemplated therein.

      (iii) Any payment due under  paragraphs  4(d)(i) and 4(d)(ii) will be made
            to or for the  benefit of such  person or  persons as the  EXECUTIVE
            shall have designated in the last unrevoked  written notice filed by
            him prior to his death with the Secretary of the Company, or, if the
            EXECUTIVE  shall have  failed to file such  written  notice or shall
            have  revoked  all such  written  notices  filed by him  during  his
            lifetime,  to his widow, or, if he shall not be survived by a widow,
            to the executors or administrators of his estate.



                                      -10-

      (iv)  The Company may in its sole discretion accelerate the payment of any
            one or more of the monthly installments payable under this paragraph
            4(d),  but neither the  designee of the  EXECUTIVE  nor the widow or
            estate of the  EXECUTIVE  will  have any  right to  demand  that any
            installment be accelerated.
