      -     that this  confidential  information  constitutes one of Contracting

      that  Manager  may  have in his  possession,  or use or have  temporarily,
      belong   exclusively  to  Contracting   Party  or  to  Third  Parties  (as
      applicable).

4.9   Manager  also  agrees not to use or exploit the  Confidential  Information

      express written authorization from Contracting Party.

4.10  As a result,  during and after the duration of this Agreement  (regardless
      of the reason for its termination), Manager undertakes:

            to third parties all or part of the confidential information;

            Information, except to save the content or file thereof on behalf of

      the  Confidential  Information  and he  shall  proceed,  upon  request  by
      Contracting  Party,  to  return  or  destroy  the  aforementioned  copies,
      regardless of their nature.

      Reservation of Intellectual and Industrial Property

4.11  Manager  assigns to Contracting  Party all the rights to exploit any works

      result of a research  activity forming part,  expressly or implicitly,  in
      whole or in part, of the objective of this agreement.

4.13  Likewise,  Contracting Party shall have a right to assume ownership of the
      inventions subject to protection,  or to reserve for itself a right of use
      thereon,  if,  even  if not an  inventive  activity  forming  part  of the
      objective of this  agreement,  such inventions are related to the activity
      of  Manager  at  Contracting   Party  and  the   obtainment   thereof  was
      predominantly  influenced by knowledge  acquired by him within Contracting
      Party,  and provided  that Manager is made aware of its decision to assume
      ownership  or reserve for itself any right of use within a period of three
      (3) months from receipt by Contracting Party of the notification.

4.14  Except in the cases  imperatively  stipulated  by the Patent Act,  Manager

            responsibilities or in which he has interests;

      (ii)  Not to  participate in commercial  acts  competing with  Contracting
            Party;

      (iii) Not  to  request   directly  or  indirectly  that  any  employee  of
            Contracting Party leave his current employment with the company.

      The "advertising accounts" and "potential clients" of this clause refer to
      the  advertising   accounts  of  public  or  private  companies  to  which

      twelve (12) months prior to the termination of this agreement.

4.16  If  Contracting  Party's  clients  are  international   clients,   Manager
      acknowledges  that  Contracting   Parties  may  apply  the  aforementioned
      employment non-competition stipulations internationally.

4.17  For such legal  effects as are  applicable,  it is  construed  that 15% of

            economic amount which added to the widow's pension she receives from
            Social Security,  results in 70% of Manager's fixed  compensation at
            the time of his death.

      b)    each of his orphaned  children  younger than  eighteen (18) years of
            age,  or in a regular  period of  university  studies,  shall have a

            pension  they  obtain  from  Social  Security,  results  in  15%  of
            Manager's fixed compensation at the time of his death.

      The sum of the  supplementary  amounts  received  by the widow and  orphan
      children,  stipulated in paragraphs a) and b), above,  may not in any case
      be more  than  100% of  Manager's  fixed  compensation  at the time of his

      Clause 6th. Termination, Suspension of Agreement and Corporate Succession

6.1   In all  cases  of  contractual  extinguishment  that  generate  a right to
      compensation  in favor of Manager  pursuant  to the  currently  applicable
      regulations, or which may generate such in virtue of future changes in the
      regulations,  such  indemnification  shall amount in general to the sum of
      the following amounts:

      -     an amount equivalent to multiplying by TWENTY-FOUR the monthly fixed
            compensation of Manager at the time the contractual extinguishment;

      -     an amount equal to multiplying  by TWO the bonus and  representation
            expenses  received by Manager in the year  immediately  prior to the
            extinguishment of the contract;

      -     The  amount  the  results  from  prorating  the  base  salary,   the
            representation   expenses  and  the  bonus   corresponding   to  the
            pre-notification  period  stipulated  in Clauses 6.7 and 6.8 of this
            Agreement.

<PAGE>

6.2   By  way  of  example  and  not   exhaustively,   the  following  cases  of
      extinguishment with a right to the  indemnification  agreed in this clause
      are listed:

      1.    Going out of business.

      2.    Disciplinary dismissal overturned or voided.

      3.    Extinguishment for objective causes.

      4.    Collective dismissal.

      5.    Force majeure.

      6.    Termination  of the  agreement by Manager based on any of the causes
            stipulated  in  paragraphs  a), b), and c) of Article  10.3 of Royal
            Decree  1382/1985.  That is to say,  for  breaches  of  contract  by
            Contracting Party, including thereunder material modification of the
            employment conditions under the stipulated regulatory terms.

            In any case, for these resolutive effects both the formal withdrawal
            of Manager's  agency and the de facto removal of the real content of
            the  management  functions  he  performs,  shall be construed as the
            aforementioned material modification of employment conditions.

      7.    Contractual  termination by Manager based on the cause stipulated in
            paragraph d) of Article 10.3 of Royal Decree  1382/1985.  That is to
            say, by corporate  succession  or change of ownership  thereof whose
            effect is a change in its governing  bodies or the content and scope
            of its principal activity,  provided that the extinguishment  occurs
            within  the  three  months  subsequent  to the  occurrence  of  such
            changes.

      8.    Contractual  termination  by Manager when, for any reason other than
            that stipulated in the preceding paragraph,  such as a change in the
            capital stock of the Group companies or any other cause,  there is a
            change in Contracting  Party's  governing  bodies or the content and
            scope of its principal  activity,  provided that the  extinguishment
            occurs within the three months  subsequent to the  occurrence of the
            aforementioned  change in  capital  stock or the  occurrence  of any
            other regardless of the cause.

6.3   Likewise  Manager  may  terminate  the  agreement  with  a  right  to  the
      indemnification  agreed in Clause 6.1 when,  for any  reason,  the current
      President-Director  General  of  Havas  Advertising,  S.A.,  Mr.  Alain de
      Pouzilhac,  ceases to provide  his  services to Havas  Advertising,  S.A.,
      provided that the  extinguishment  occurs within the six months subsequent
      to the aforementioned removal,  severance, or effective  extinguishment of
      the functions of the President-Director General.

6.4   In particular,  when Manager was able to exercise but did not exercise the
      resolutive  authority  stipulated  in  numbers 7 and 8 of  paragraph  6.2,
      above, but the agreement is extinguished for any of the other causes cited
      in paragraphs 6.2 and 6.3, the

                                       13
<PAGE>

      indemnification  to be received by Manager  shall be that agreed in Clause
      6.1 of this agreement.

                                       14
<PAGE>

6.5   In any case, the corresponding  severance wages [salarios de tramitacion],
      plus the liquidation  amount that might be pending,  shall be added to the
      indemnification cited in the preceding paragraphs.

6.6   Notwithstanding the aforesaid,  this indemnification clause shall not take
      effect when the  agreement  is  extinguished  by  resignation  of Manager,
      disciplinary  dismissal  confirmed  or not  challenged  judicially,  or by
      retirement,  death,  major  or  permanent  absolute  or  total  disability
      Manager.

      Advance Notification

6.7   As  stipulated  in Article  10.1 of Royal  Decree  1382/1985,  Manager may
      extinguish the agreement through voluntary resignation,  with at least six
      (6) months' advance written  notification.  Contracting Party shall have a
      right, in case of full or partial breach of the advance notification duty,
      to   indemnification   equivalent  to  the  amount  of  all  the  economic
      compensation corresponding to the time remaining in such period.

6.8   As stipulated in Art. 11 of Royal Decree 1382/1985,  Contracting Party may
      abandon the agreement,  notifying Manager of such in writing, with six (6)
      months' advance notification.  If such advance notification is breached in
      full or in part,  it shall be  obligated to pay the amount of all economic
      compensation corresponding to the time remaining in such period.

      Suspension of Agreement

6.9   If as a result of the  appointment of Manager to perform  functions of the
      corporate  management  body,  there is a conflict of interest  between his
      special  employment  relationship with the commercial one inherent to such
      integration,   this  special  senior-management   relationship  shall  not
      extinguish,  but  rather it shall be  suspended,  the time  elapsed  being
      calculated for all effects, such that the suspension period shall be taken
      into  consideration  for the effects of  seniority,  compensation  and, if
      applicable, indemnification.

6.10  If for any reason Manager  ceases to be a Director,  the suspension of the
      special  employment  relationship  would be raised,  the present agreement
      taking effect again and the special  employment  bond being  reestablished
      with the  compensation  that he would receive if the agreement had been in
      effect during the entire suspension period.

6.11  In such case, if Contracting  Party besides relieving him of his duties as
      Director,  sought  to do  without  Manager's  services,  it shall  pay the
      indemnification established in this clause as applicable.

      Company Succession

6.12  The  present  agreement  shall bind Media  Planning,  S.A.,  and any other
      applicable  company,  by express application of Article 44 of the Employee
      Act in all the cases such article stipulates, and the agreement

                                       15
<PAGE>

      shall be  maintained  and  respected in its  entirety by the  liquidators,
      successors,  acquirers,  etc.,  of Media  Planning  Group,  S.A., it being
      committed to give advance  notice to third  parties of this clause and the
      obligation to maintain the provisions of this agreement.

6.13  In all the cases mentioned,  in addition to the preceding guarantee, it is
      likewise agreed that Contracting  Party and its Group shall be jointly and
      severally  liable  with  the  successor  entity,  for the  indemnification
      obligations contained in this clause.

6.14  All the aforesaid is agreed without prejudice to the extinctive  authority
      with right to indemnification  stipulated in numbers 6, 7, and 8 of Clause
      6.2 of this agreement.

6.15  The agreement  shall be maintained as a unique  senior-management  special
      employment  relationship,  without  prejudice to  Manager's  being able to
      provide his services,  which shall necessarily be those appropriate to his
      position,  in another  Entity,  either those that ipso jure currently form
      part of Grupo Media Planning Group, or those that might form part of it in
      the future by horizontal or vertical  disaggregation of the existing ones,
      or be  established as new ones in the  aforementioned  Group or in another
      manner of association.

      Clause 7th. Legislation

7.1   For all matters not regulated by the present agreement,  the provisions of
      Royal Decree 1382/1985, of August 1, which regulates the special nature of
      the employment  relationships  of Senior  Management  personnel,  shall be

      preferentially  applicable legal precept,  and, in the absence thereof, to
      general labor law.

      Clause 8th. Jurisdiction

8.1   If this relationship is declared commercial, civil, or a common employment
      relationship by judicial entities or arbitration,  conciliation  bodies or
      an administrative  authority,  such shall not be an impediment to applying
      the clauses of this agreement in their  entirety,  even when the competent
      jurisdiction is not labor.

confirm and sign it in duplicate,  both copies having the same force and effect,
