further provisions of this ARTICLE 12, AG Telecom and AG Parent (jointly and
severally as between them) on the one hand, and Socma, on the other hand (each
of which is an "INDEMNITOR") will, severally but not jointly, indemnify and hold
                ----------                                                      
harmless Equifax and Equifax's Affiliates (which for purposes of ARTICLE 12 of
this Agreement does not include Partech, Unnisa or Proceda) and their respective
officers, directors, agents and employees (collectively, "INDEMNITEES"), from
                                                          -----------        
and against and in respect of any and all loss, damage, Liability, cost and
expense, including reasonable attorneys' fees and amounts paid in settlement
(collectively, the "INDEMNIFIED LOSSES"), suffered or incurred by any one or
                    ------------------                                      
more of the Indemnitees by reason of, or arising out of:

           (a) any misrepresentation, breach of warranty or breach or
nonfulfillment of any agreement of the Sellers, any other member of the AG
Group, any other member of the Socma Group, Partech, Unnisa or Proceda contained
in this Agreement, any Additional Agreement, or in any other certificate,
schedule, instrument or document delivered to Equifax by or on behalf of Sellers
or Partech pursuant to or in connection with the provisions of this Agreement or
any Additional Agreement;

           (b) all liabilities and obligations of, or claims, demands or actions
against, Equifax or Equifax's Affiliates, Partech, Unnisa or Proceda of any
nature whatsoever, whether known or unknown, accrued, absolute, contingent or
otherwise, existing as of the date of this Agreement or at any time hereafter
relating to periods on or prior to the Closing Date, to the extent not reflected
in the relevant balance sheets or

                                      38

 
included in the Unaudited Financial Statements, including without limitation:
(i) any Tax liabilities (to the extent not so reflected or reserved against)
accrued in respect of, or measured by the income of, Partech, Unnisa or Proceda
for any period or portion of a period on or prior to the Closing Date or arising
out of transactions entered into or any state of facts existing on or prior to
the Closing Date; (ii) any claims or liabilities arising out of any act or
omission of Partech, Unnisa or Proceda or any of its directors, officers, agents
or employees or any claims or liabilities with respect to defective, or
allegedly defective, goods or services; or (iii) any claim or liability arising
out of a breach by Partech, Unnisa or Proceda of any Contract relating to any
period on or prior to the Closing Date allegedly defective, goods or services;
or (iii) any claim or liability arising out of a breach by Partech, Unnisa or
Proceda of any contract relating to any period on or prior to the Closing Date;
it being understood that, in no event whatsoever, none of AG Telecom, AG Parent
nor Socma shall be held responsible for any damages or losses arising as a
result of Unnisa or Proceda or their respective customers or suppliers not being
Year 2000 Compliant.

           (c) the use of any Proprietary Rights, whether before or after the
Closing Date, and whether by Partech, Unnisa or Proceda, other than for the use
of any Proprietary Rights after the Closing Date not in compliance with any
related Contract;

           (d) any and all Actions, suits, proceedings, claims, demands,
assessments, judgments, fees and expenses, incident to any of the foregoing or
incurred in investigating or attempting to avoid any Actions, suits,
proceedings, claims, demands, assessments, judgments, fees and expenses or to
oppose the imposition of any Actions, suits, proceedings, claims, demands,
assessments, judgments, fees and expenses, or in enforcing this Agreement in
connection with any breach or default or threatened breach or default by an
Indemnitor, including without limitation the provisions of this ARTICLE 12.

     12.2  PAYMENT.  Subject to the provisions of PARAGRAPH 12.3 below, (i)
after a final, non-appealable judgment has been rendered or a settlement has
been reached in respect of a third party claim or  Action, or (ii) in the case
of a claim for Indemnified Losses arising other than pursuant to a third party
claim or Action, after the award of the Arbitral Body has been issued or a
settlement has been reached, Indemnitor shall reimburse the Indemnitees within
30 days of written demand on the Indemnitor for any amounts to which Indemnitees
are entitled to indemnification pursuant to this ARTICLE 12.

     12.3  DEFENSE OF CLAIMS.

           (a) Except as provided in PARAGRAPH 12.3(B), if any Action by a third
party arises after the date of this Agreement for which Indemnitor may be liable
under the terms of this Agreement, then the Indemnitees will notify Indemnitors
in accordance with the provisions of this ARTICLE 12, and will give Indemnitors
a reasonable opportunity:

           (i) to conduct any proceedings or negotiations in connection with the
Action and necessary or appropriate to defend the Indemnitees;

                                      39

 
          (ii)   to take all other required steps or proceedings to settle or
defend any Action; and

          (iii)  to employ counsel reasonably acceptable to Indemnitees to
contest any Action in the name of the Indemnitees or otherwise.

The expenses of all proceedings, contests or lawsuits with respect to the
Actions will be borne by Indemnitors.

          (b)    If Indemnitors do not assume the defense of, or if after so
assuming the Indemnitors fail to defend, any Action, then the Indemnitees may
defend against any claim or Action in the manner they may deem appropriate and
the Indemnitees may settle any claim or Action on the terms they deem
appropriate, and Indemnitors will promptly reimburse the Indemnitees for the
amount of all expenses, legal and otherwise, reasonably and necessarily incurred
by the Indemnitees in connection with the defense against and settlement of any
claim or Action.  If no settlement of any claim or Action is made, Indemnitors
will satisfy any judgment rendered with respect to any claim or in any Action,
before the Indemnitees are required to do so, and pay all expenses, legal or
otherwise, reasonably and necessarily incurred by the Indemnitees in the defense
of any claim or Action.

          (c)    If a judgment is rendered against any of the Indemnitees in any
Action covered by the indemnification under this Agreement, or any Lien in
respect of any judgment attaches to any of the assets of any of the Indemnitees
or Partech, Unnisa or Proceda, Indemnitors will immediately upon any entry or
attachment pay the relevant judgment in full or discharge the relevant Lien
unless, at the expense and direction of Indemnitors, an appeal is taken under
which the execution of the judgment or satisfaction of the Lien is stayed.  If
and when a final judgment is rendered in any action, Indemnitors will forthwith
pay any judgment or discharge any Lien before any of the Indemnitees is
compelled to do so.

          (d)    Any notice required to be given to Indemnitors pursuant to
PARAGRAPH 12.3(A) shall be given no later than the latter of: (i) the end of the
first half of the term within which an answer or other response to the Action is
required to be made (the "ANSWER PERIOD") and (ii) two Business Days after
                          -------------                                   
receipt by an Indemnitee of notice of the Action. Indemnitors shall assume the
defense of any Action, if at all, by notice to Indemnitees no later than the
earlier of: (i) the end of the second third of the Answer Period and (ii) three
Business Days prior to the date by which an answer or other response to the
Action is required to be made. Indemnitors' failure to notify Indemnitees within
the specified time shall be conclusively deemed an election by Indemnitors not
to assume such defense. Any failure by Indemnitees to give the requisite notice
within the time specified in this PARAGRAPH 12.3(D) will not relieve Indemnitors
of the obligation to indemnify Indemnitees pursuant to this ARTICLE 12 except to
the extent that the defense of any Action is materially prejudiced by the delay.

                                      40

 
           (e) The Indemnitors or the Indemnitees, as appropriate, shall have
the right to participate in the defense of any Action related to an Indemnified
Loss at their sole cost and expense and the cost and expense of that
participation shall not be an Indemnified Loss. Notwithstanding anything
contained in this ARTICLE 12 to the contrary, Indemnitors may not settle any
claim or Action, without the prior approval of Indemnitees, which approval shall
not be unreasonably withheld, delayed or conditioned.

     12.4  INDEMNIFICATION OF SELLERS BY EQUIFAX. Equifax will indemnify and
hold harmless Sellers, the AG Group and the Socma Group from and against and in
respect of any and all loss, damage, Liability, cost and expense, including
reasonable attorneys' fees and amounts paid in settlement suffered or incurred
by any one or more of them by reason of, or arising out of: (i) any
misrepresentation, breach of warranty or breach or nonfulfillment of any
agreement of Equifax contained in this Agreement or in any certificate,
schedule, instrument or document delivered to Sellers by or on behalf of Equifax
pursuant to the provisions of this Agreement or any Additional Agreement; and
(ii) any and all Actions, suits, proceedings, claims, demands, assessments,
judgments, fees and expenses, incident to any of the foregoing or incurred in
investigating or attempting to avoid any Actions, suits, proceedings, claims,
demands, assessments, judgments, fees and expenses or to oppose the imposition
of any Actions, suits, proceedings, claims, demands, assessments, judgments,
fees and expenses, or in enforcing this Agreement, including without limitation
the provisions of this PARAGRAPH 12.4.

     12.5  LIMITATION ON LIABILITY. Notwithstanding anything in this ARTICLE
12 to the contrary, in any case in which both the AG Group and the Socma Group
are liable with respect to the same Indemnified Losses, their liability shall
not be joint but shall instead be several and proportional to their respective
equity interests in Partech immediately prior to the Closing.  The obligation of
the AG Group and the Socma Group to indemnify the Indemnitees shall be net of
any tax effects directly accruing to the Indemnitees directly related to the
Indemnified Losses.  The AG Group and the Socma Group shall only be liable to
indemnify the Indemnitees in respect of Indemnified Claims once the aggregate
Indemnified Claims exceed R$ * * *, and only in respect of those Indemnified
Claims in excess of R$ * * *; provided, however, if the aggregate Indemnified
                              --------  -------                              
Claims exceed R$ * * *, the AG Group and the Socma Group shall reimburse
Indemnitees for the first R$ * * * of Indemnified Claims not previously
reimbursed.

     12.6  NO CONTRIBUTION BY PARTECH, UNNISA OR PROCEDA.  Partech, Unnisa or
Proceda will not have any Liability to either or both Sellers, or any other
member of either the AG Group or the Socma Group, as a result of any
misrepresentation or breach of representation or warranty by Partech, Unnisa or
Proceda contained in this Agreement, any Additional Agreement or any
certificate, schedule, instrument, agreement or other writing delivered by or on
behalf of, or in respect of, Partech, Unnisa or Proceda pursuant to this
Agreement, any Additional Agreement or in connection with the transactions
contemplated by this Agreement or any Additional Agreement, or the breach of any

                                      41

 
covenant or agreement of Partech, Unnisa or Proceda contained in this Agreement,
any Additional Agreement or any certificate, schedule, instrument, agreement or
other writing by or on behalf of, or in respect of, Partech, Unnisa or Proceda
pursuant to the terms of this Agreement or any Additional Agreement or in
connection with the transactions contemplated by this Agreement or any
Additional Agreement. Neither AG Telecom nor Socma, nor any other present or
future member of the AG Group or the Socma Group, will have any right of
indemnification or contribution against Partech, Unnisa or Proceda on account of
any event or condition occurring or existing prior to or on the date of this
Agreement or the Closing Date.

provisions of this Agreement or any Additional Agreement and will continue in
full force and effect for the periods specified below (the "SURVIVAL PERIOD"):

indefinitely;

           (b) representations and warranties relating to labor and employment
claims, employee benefit matters, and Taxes will survive until expiration of any
applicable statute or period of limitations, and any extensions of the
applicable statute or period of limitations; and

           (c) all other representations, warranties, covenants, agreements and
indemnities will be of no further force and effect after the expiration of three
(3) years from the Closing Date;

Provided, however, that any claim for an Indemnified Loss presented in writing
- --------  -------                                                             
to the indemnifying party (together with any relevant supporting documentation)
in accordance with the terms of this Agreement within the Survival Period will
continue to be a valid claim until resolved.

          This Agreement may be terminated at any time prior to or on the
Closing Date by Equifax or by Sellers, upon written notice to the other as
follows:

          (a)  By Equifax, if (i) the results of its due diligence investigation
                  -------                                                       
of Partech, Unnisa and Proceda reveal Liabilities in excess of R$ * * *, which
Liabilities are not properly reflected in the Unaudited Financial Statements, or
(ii) there is an adverse change in the condition or value (financial or
otherwise) of any of Partech, Unnisa or Proceda, individually or in the
aggregate, or in their respective assets, properties, businesses, liabilities or
operations, in excess of R$ * * *.

          (b)  By Sellers, if the terms, covenants or conditions of this
                  -------                                               
Agreement to be complied with or performed by Equifax at or before the Closing

or threatened against any party to this Agreement to restrain or prohibit, or to
obtain substantial damages in respect of, this Agreement or the consummation of

          (b)  If for any reason on the Closing Date there has been
nonfulfillment of an undertaking by or covenant for Equifax or for AG Telecom
and Socma not waived in writing by or on behalf of the Party in whose favor the
undertaking or covenant runs, the Party in whose favor the undertaking or
covenant runs, in addition to any other right or remedy available to it for
breach or non-performance of this Agreement or any Additional Agreement, may
refuse to consummate the transactions contemplated by this Agreement without
Liability or obligation on its part whatsoever.  Notwithstanding the foregoing,
the obligations of the Parties pursuant to PARAGRAPHS 4.3, 4.5, 4.6, 13.1, 14.1,

conflict between the Rules and the provisions of this Agreement.  The
arbitrators will decide the issues submitted in accordance with the provisions
and commercial purposes of this Agreement, provided that 

                                      46

 
all substantive questions of law will be determined under the laws of Brazil
(without regard to the principles of conflicts of laws of any relevant state and
country). All decisions of the arbitrators will be in writing and submitted to
the Parties, and will set forth findings of fact and conclusions of law.

          (d)  The Parties will facilitate the arbitration by: (i) making
available to one another and to the arbitrators for examination, inspection and
extraction all documents, books, records and personnel under their control if
determined by the arbitrators to be relevant to the Disputed Matter; (ii)
conducting arbitration hearings to the greatest extent possible on successive
days; and (iii) observing strictly the time periods established by the Rules or
by the arbitrators for submission of evidence or briefs.

          (e)  In the final award, the arbitrators will divide all costs, other
than fees of counsel, incurred in conducting the arbitration, in any manner as
the arbitrators deem just and equitable under the circumstances.  Judgment on
the award of the arbitrators may be entered into by any court having
jurisdiction over the Party against whom enforcement of the award is being
sought.

          (f)  Each Party agrees that any award of the arbitrators against it
and on which judgment is entered may be executed against the assets of that
Party in any jurisdiction, including Brazil and the United States of America. By
execution of this Agreement, each Party irrevocably consents to the jurisdiction
of any court having jurisdiction over that Party for the purpose of enforcing
any award. Each of the Parties irrevocably consents to the service of process by
registered mail, postage prepaid, international express courier, or by personal
service within or without Argentina, Brazil or the State of Georgia or the State
of New York, to the fullest extent permitted by applicable Law. Each of the

and local agent to receive for and on behalf of that Person, service of process
in such respective jurisdictions in any arbitration, legal action or proceeding.

          (g)  Each Party irrevocably waives, to the fullest extent permitted by
law, any objection it may now or hereafter have to any suit, Action or
proceeding arising out of or relating to this Agreement that is brought in any
jurisdiction designated in the preceding subparagraph, and further irrevocably
waives any claim that any suit, Action or proceeding so brought has been brought
in an inconvenient forum.

          (h)  Notwithstanding any provision of this PARAGRAPH 15.5 to the

     15.7  PARTIAL INVALIDITY AND SEVERABILITY.  All rights and restrictions
contained in this Agreement may be exercised and will be applicable and binding
only to the extent that they do not violate any applicable laws and are intended
to be limited to the extent necessary to render this Agreement legal, valid and
enforceable.  If any term of this Agreement, or part of this Agreement, not
essential to the commercial purpose of this Agreement will be held to be
illegal, invalid or unenforceable by a court of competent jurisdiction, it is
the intention of the Parties that the remaining terms of this Agreement, or part
of this Agreement, will constitute their agreement with respect to the subject
matter of this Agreement and all remaining terms, or parts of this Agreement,
will remain in full force and effect.  To the extent legally permissible, any
illegal, invalid or unenforceable provision of this Agreement will be replaced
by a valid provision which will implement the commercial purpose of the illegal,
invalid or unenforceable provision.

     15.8  WAIVER.  Any term or condition of this Agreement may be waived at
any time by the Party which is entitled to the benefit of the term, but only if
the waiver is evidenced by a writing signed by the relevant Party.  No failure
on the part of any Party to this Agreement to exercise, and no delay in
exercising any right, power or remedy created under this Agreement, will operate
as a waiver thereof, nor will any single or partial exercise of any right, power
or remedy by any Party preclude any other or further exercise thereof or the
exercise of any other right, power or remedy.  No waiver by any Party to this
Agreement or any breach of or default in any term or condition of this Agreement
will constitute a waiver of or assent to any succeeding breach of or default in
the same or any other term or condition of this Agreement.

     15.9  HEADINGS.  The headings of particular provisions of this Agreement
are inserted for convenience only and will not be construed as a part of this

provision of this Agreement.
