         Date,  with people  related to the Company which could in the future be

         agencies, etc.) as a "labor relation."

5.19     The  Seller  has not  incurred  nor will it  incur,  be it by action or
         omission,  in  conducts  which may  prevent or hinder  approval  of the
         transfer of the Equity Interest by the CNC.

         Schedule 5.26. The payment of the premiums on said policies are in good
         standing.  Neither the Company nor its  counterparts  are in default in

5.23     Y2K

         All products, computer assets and/or services, including, among others,
         any  kind of  hardware  components  or  software  programs  used by the
         Company,  have not been affected in their correct and normal  operation
         prior to or  simultaneously  with 9  September  1999,  nor will they be
         affected  after said  date,  with  respect  to the data,  calculations,
         output  information  or  other  functions  (including,   among  others,
         calculation,  comparison  and  sequence)  which are  date-dependant  or
         date-related,  and that said  information  technology  products,  goods
         and/or services shall create,  store,  process and/or output (as may be
         the case) date-related or containing dates without errors or omissions.
         The Company has taken all necessary preventive measures so that after 9
         September  1999 the  effects  that the  information  technology  crisis
         presents  for the year 2000  shall in no way  affect  any of the normal
         Company activities, including, as an illustration, the rendering of the
         Service, and that, for the same reason, the greatest diligence has been
         applied  to the  review of all  supply  circuits,  both of  assets  and
         services,  which currently and/or at the time foreseen for the onset of
         the  information  technology  crisis (1 January 2000) and for the whole
         duration of the same,  may be necessary to satisfy,  as a minimum,  the
         Company's   customary  needs  and  allow  for  its  normal   operation,
         understanding  as such that  maintained  prior to 9 September 1999. The
         Company has complied with the CNC's rules regarding Y2K.

6.       Administrative Approval.

         Both parties shall be responsible  for obtaining the CNC's approval for
         the Buyer to become  the owner of the  Equity  Interest.  Both  parties
         commit  their  best  efforts  to  assist  the Buyer in  obtaining  such
         authorization  as  soon  as  possible  and  to  provide  their  maximum
         cooperation to respond to any requirement from the CNC. Any expenses to
         be  incurred  to obtain it will be borne by the  Buyer.  Should the CNC
         fail to grant such approval, the Buyer shall have the right to sell its
         shares in part or in total and  assign  this  Agreement,  in part or in
         total, to a third party,  providing  notice thereof to the Seller,  but
         without the need to require his consent. Likewise, the Buyer shall have
         the option,  until finding a substitute  susceptible of approval by the
         CNC, of  reselling  2% of the Company  shares to the Seller who will be
         obliged  to buy then at the same price per share at which the Buyer has
         bought  them.  Any delays which may arise in  obtaining  said  approval
         shall not affect the terms indicated in this Agreement.

         Until such time as the CNC decides on the  approval of the  transfer of
         shares  (and  should  it  fail to be  approved,  until  an  alternative
         transfer  to  a  company  designated  by  the  Buyer  shall  have  been
         approved),  the  Buyer  shall  notwithstanding  have,  in the  internal
         shareholders'  relation between the parties,  all the rights pertaining
         to  shareholders,  for which purpose the Seller herein grants the Buyer
         an irrevocable  power of attorney,  effective as from the Closing Date,
         attached  hereto as Schedule 6 and further commits to execute any other
         documents which may be required.

7.       Non Performance

7.1      Seller's Non Performance


7.1.1    In case of non  performance  by the  Seller  of any of his  obligations
         under this  Agreement,  including,  among others,  if the inaccuracy or
         falseness of any of the  representations  and  warranties  contained in
         Clause 5 was  demonstrated  and such  inaccuracy  or falseness  was not
         remedied  within thirty (30)  business days of having been  effectively
         served notice to that end, or if there was any Hidden Liabilities,  the
         Seller  will be  jointly  and  severally  liable  to the  Buyer for the
         damages that he or the Company may suffer for such reason.

7.1.2    Defense

         In  case  the  Seller  considered  that  the  Hidden   Liabilities  are
         inappropriate,  and to the extent the Seller shall have  complied  with
         his  obligations  under Clause 7.1.2,  the Seller may defend such claim
         through the legal  counsel  appointed by him at his  expense,  in which
         case he shall serve  effective  notice to the Buyer  indicating he will
         undertake  such  defense.  To this end,  the Buyer  shall  provide  the
         information  required  by the  Seller and grant the  special  powers of
         attorney of the case,  with  prohibition to substitute and settle.  The
         Seller shall not,  without the previous  written  consent of the Buyer,
         settle or offer to settle any claims or actions for a Hidden  Liability
         nor offer for seizure Company assets or invoke allegations which in the
         opinion of the  Company's  lawyers could be used against the Company in
         another  case.  The Seller shall provide the Buyer with written copy of
         any writ or document, before its presentation to the judge or competent
         authority. If the Seller shall fail to assume the defense of such claim
         within a reasonable  time, the Buyer shall have the right,  but not the
         obligation,  of assuming  the  defense of the same.  If the Buyer shall
         assume such  defense,  it shall be exercised  with  diligence,  and the
         Seller  shall be bound by the result  obtained by the Buyer with regard
         to such claim, in which case the Seller will also be accountable to the
         Buyer for the legal fees set by the court and such reasonable  costs as
         may have  been  incurred  in such  defense.  In case the  Seller  shall
         demonstrate  the third party claim to be  groundless,  then the Company
         shall  reimburse him,  within 30 calendar days of the request,  for any
         expenses and fees incurred by the Seller.

7.1.3    Currency

         For the purpose of the  deductions or  withholdings  or  reimbursements
         contemplated  in this clause,  any Argentine  Peso  denominated  Hidden
         Liability  shall be converted into Dollars at the seller  exchange rate
         set by Banco de la Nacion Argentina effective on the date it is paid by
         the Company or the Buyer,  or the date the Buyer  deducts it, as may be
         the case.

7.2      Non Performance by the Buyer.

         (a)      In case of non  performance by the Buyer in the payment of the
                  Price not remedied  within five (5) calendar days of effective
                  notice having been served,  the Seller shall have the right to
                  chose between two options to demand payment, plus a 10% annual
                  interest,  from the date of default  until the payment date or
                  cause the buyer to loose the rights of  purchase  without  any
                  type of judicial or extrajudicial claim.

                  allowed  by the law,  to  compensate  Withdrawals  on  Account
                  against  non-allocated   results.  The  Directors  shall  have

                  not be computed for the purpose of  calculating  the Company's
                  Shareholders'  Equity  pursuant to clause 3.3 but shall not be
                  transferred if this has an effect on the net worth and affects

9.       Performance Events After the Closing Date

9.1      The  parties  recognize  that the Company  shall have set up,  prior to

         personal  sureties to the Company to the extent that it may be required
         for the Company to set up such  sureties.  If one of the parties  shall
         fail to perform his obligation of  capitalizing  the Company or setting
         up  personal  sureties,  then the other  party  shall have the right to
         collect from the  non-



         performing party a penalty equivalent to two (2) times the total amount
         of the surety to be set up by the Company.

10.      Jurisdiction

         Except  for the  provisions  of Clause  3.3,  any  controversy  arising
         between the parties in connection with this  Agreement,  its existence,
         validity,  interpretation or performance, (the "Controversy"),  will be
         submitted to the  mediation  procedure of the Rules of the  Arbitration
         Court of the Buenos Aires Stock Exchange.  Any Controversy which is not
         resolved  under  the  previous  procedure  will  be  subject  to  legal
         arbitration  in  accordance  with such  Rules.  The award  shall not be
         subject to appeal.

12.      Prohibition to Compete

         The Seller shall not directly or indirectly  through a company of which
         he is a part  currently  or in the  future,  as  partner,  shareholder,
         director or executive, take part in activities which compete with those
         carried out by the Company in the Republic of Argentina; with competing
         activities being  understood as any type of Internet related  services,
         for a period of 10 years  counted as from the Closing  Date.  Likewise,
         the Seller may carry out activities  not comprised  among the competing
         activities   and,  in  that  case,   will  offer  the   possibility  of
         participating in such development  first to the Company and then to the
         Buyer,  before  offering  it to any third  party.  In case the  Company
         and/or the Buyer, as may be case, did fail to accept  participating  in
         such  development,  the Seller may present it to other persons or carry
         it out on his own. The Seller declares that undertaking this commitment
         of non  competition is



         reasonable and justified since both the Seller and the Buyer have taken
         it  into  account  at the  time of  fixing  the  Price.  In case of non
         performance  of this  obligation,  the Seller shall pay the Buyer a sum
         equivalent  to two (2) times the annual  billings  of the  business  in
         competition with that of the Buyer.

13.      Construction: Severability

         Each of the provisions in this Agreement shall be considered severable.
         If, for any reason, any of such provisions was declared null, this will
         not affect the validity of the others.

14.      Sundry.

14.1     This Agreement  reflects the totality of the agreements  reached by the
         parties,  renders void any oral or written pre-dated  agreement and can
         only be modified in writing,  with the signature of both  parties.  For
         the  purposes  of  this  Agreement,   the  Schedules  hereto  shall  be
         considered part of the Agreement.

14.2     This  agreement  shall  be  ruled  and  construed  in  accordance  with
         Argentine Law.

14.3     The words appearing capitalized herein shall have the meanings assigned
         to them in Clause 1 herein or any other Clauses in this Agreement where
         they appear written between brackets and quotation marks.

14.4     None of the parties shall  publicly  announce or disclose the execution
         of this transaction without the other's consent.

In witness  whereof,  the parties have caused two copies of this agreement to be
executed with the same contents and for the same purpose.
