ITEM 17. UNDERTAKINGS

     The undersigned hereby undertakes:

          (a) The undersigned registrant hereby undertakes to provide to the
     underwriters at the closing specified in the underwriting agreement
     certificates in such denominations and registered in such names as required
     by the underwriter to permit prompt delivery to each purchaser.

                                      II-4

          (b) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the registrant pursuant to the foregoing provisions,
     or otherwise, the registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Securities Act of 1933 and is, therefore,
     unenforceable. In the event that a claim for indemnification against such
     liabilities (other than the payment by the registrant of expenses incurred
     or paid by a director, officer, or controlling person of the registrant in
     the successful defense of any action, suit or proceeding) is asserted by
     such director, officer or controlling person against the registrant in
     connection with the securities being registered, the registrant will,
     unless in the opinion of its counsel the matter has been settled by
     controlling precedent, submit to a court of appropriate jurisdiction the
     question whether such indemnification by it is against public policy as
     expressed in the Act and will be governed by the final adjudication of such
     issue.

          (c) The undersigned registrant hereby undertakes that:

             (1) For purposes of determining any liability under the Securities
        Act of 1933, the information omitted from the form of prospectus filed
        as part of this registration statement in reliance upon Rule 430A and
        contained in a form of prospectus filed by the registrant pursuant to
        Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed
        to be part of this registration statement as of the time it was declared
        effective.

             (2) For the purpose of determining any liability under the
        Securities Act of 1933, each post-effective amendment that contains a
        form of prospectus shall be deemed to be a new Registration Statement
        relating to the securities offered therein, and the offering of such
        securities at that time shall be deemed to be the initial bona fide
        offering thereof.

          (d) The undersigned hereby undertakes to provide to the underwriters
     at the closing specified in the underwriting agreement, certificates in
     such denominations and registered in such names as required by the
     underwriters to permit prompt delivery to each purchaser.

                           to confer personal jurisdiction over the Company in
                           any such action;

                  (vi)     The statements set forth in the Prospectus under the
                           caption "Taxation United States Taxation", to the
                           extent that they constitute matters of U.S. federal
                           income tax laws or conclusions pertaining thereto,
                           fairly present the information therein in all
                           material respects;

                  (vii)    The Company is not and, after giving effect to the
                           offering and sale of the International Shares and
                           ADSs and the application of the proceeds thereof, as
                           described in the Prospectus, will not be required to
                           register as an "investment company", as such term is
                           defined in the Investment Company Act;

                  (viii)   Nothing has come to such counsel's attention that
                           causes such counsel to believe that (A) the ADS
                           Registration Statement, the Registration Statement or
                           the prospectus included therein (except for the
                           financial statements and related schedules therein,
                           as to which such counsel need express no belief) do
                           not comply as to form in all material respects with
                           the requirements of the Act and the applicable rules
                           and regulations of the Commission thereunder, or
                           (B)(1) either the Registration Statement and the
                           prospectus included therein (except for the financial
                           statements and related schedules included therein, as
                           to which such counsel need express no belief) or the
                           ADS Registration Statement, at the time the
                           Registration Statement or the ADS Registration
                           Statement, as the case may be, became effective,
                           contained an untrue statement of a material fact or
                           omitted to state a material fact required to be
                           stated therein or necessary to make the statements
                           therein not misleading or (2) the Prospectus (except
                           as stated) as of its date and as of the date of such
                           opinion


                                      -22-
<PAGE>   23
                 contained or contains an untrue statement of a material fact or
                 omitted or omits to state a material fact necessary in order to
                 make the statements therein, in the light of the circumstances
                 under which they were made, not misleading; and such counsel do
                 not know of any amendments to the Registration Statement or the
                 ADS Registration Statement required to be filed or any
                 contracts or other documents of a character required to be
                 filed as an exhibit to the Registration Statement or the ADS
                 Registration Statement or required to be described in the
                 Registration Statement or the ADS Registration Statement or the
                 U.S. Prospectus which are not filed or incorporated by
                 reference or described as required; and

                         (ix) Such counsel has been informed by the Commission
                 that the Registration Statement and the ADS Registration
                 Statement have become effective under the Act, and, to the best
                 of such counsel's knowledge, no stop order suspending the
                 effectiveness of the Registration Statement or the ADS
                 Registration Statement has been issued and no proceedings for
                 that purpose have been instituted or threatened.

In giving such opinion, such counsel may state that (w) they have assumed that
any documents referred to in their opinion and executed by the Company have been
duly authorized, executed and delivered pursuant to Spanish law; (x) to the
extent that the laws of Spain are relevant to such opinion, such counsel has
assumed the effect of the laws of Spain as stated therein and may rely with
respect thereto, without independent investigation, upon the opinions of Spanish
counsel described in paragraph (d)(Y) of this Section 7; and (y) they have not
themselves checked the accuracy or completeness of, or otherwise verified, the
information furnished with respect to matters in the Registration Statement, the
ADS Registration Statement or the Prospectus other than as specified above, but
have generally reviewed and discussed with representatives of the International
Underwriters and with certain officers and employees of, and counsel and
independent accountants for, the Company the information furnished, whether or
not subject to their check and verification, and that their opinion is rendered
on the basis of such consideration, review and discussion, but without
independent check or verification, except as so specified.

                 (d) (X) Garrigues & Andersen, Spanish counsel for the
Underwriters, and (Y) Uria y Menendez, Spanish counsel for the Company shall
have furnished to you their written opinions, dated such Time of Payment, in
form and substance satisfactory to you, to the effect that:

                         (i) The Company has been duly incorporated and is
                 validly existing as a corporation with limited liability
                 (sociedad anonima) in good standing under the laws of Spain,
                 with full power and authority (corporate and other) to own or
                 lease and operate its properties and conduct its business as
                 described in the Prospectus;

                         (ii) Such counsel has no reason to believe that the
                 Spanish "Folleto Informativo Completo" filed with the CNMV on
                 October 29, 1999, and any further amendments or supplements
                 thereto, did not conform in all material respects to the
                 requirements of Spanish law and the rules and regulations of
                 the CNMV or, as of its applicable


                                      -23-
<PAGE>   24
                 effective or filing date, contained or contains an untrue
                 statement of a material fact or omitted or omits to state a
                 material fact required to be stated therein or necessary to
                 make the statements therein, in light of the circumstances
                 under which they were made not misleading;

                          (iii) The Company has an authorized capitalization as
                 set forth in the Prospectus, and all of the issued shares of
                 capital stock of the Company have been duly and validly
                 authorized and issued, and are fully paid and non-assessable
                 and conform in all material respects to the description of the
                 capital stock of the Company contained in the Prospectus; the
                 holders of outstanding shares of capital stock of the Company
                 or any other person, including parties to any of the
                 Transaction Documents, are not entitled to preemptive or other
                 rights to acquire the Shares or the ADSs which have not been
                 complied with; there are no outstanding securities convertible
                 or exchangeable for, or warrants, rights or options to purchase
                 from the Company or obligations of the Company to issue,
                 ordinary shares or any other class of capital stock of the
                 Company; the International Shares may be freely deposited by
                 the Company with the Depositary against issuance of ADRs
                 evidencing ADSs; the Shares and the ADSs are freely
                 transferable by the Company to or for the account of the
                 several International Underwriters and the initial purchasers
                 in the manner contemplated in the Underwriting Agreements; and
                 there are no restrictions on subsequent transfers of the ADSs
                 or the Shares except as described in the Prospectus under
                 "Description of Capital Stock --Restrictions on foreign
                 investment";

                         (iv) The Deposit Agreement has been duly authorized,
                 executed and delivered by the Company and, assuming the Deposit
                 Agreement constitutes a valid and legally binding agreement
                 under New York law, constitutes a valid and legally binding
                 agreement of the Company, enforceable in accordance with its
                 terms, subject, as to enforcement, to applicable bankruptcy,
                 insolvency, fraudulent transfer, suspension of payments or
                 other laws of general applicability relating to or affecting
                 creditors' rights and to general equity principles; detailed
                 information relating to any payment by the Company pursuant to
                 Section 5.08 thereof will be required to be given to the
                 Spanish Registry Entity through which such payment is made;

                         (v) The Agency Agreement has been duly authorized,
                 executed and delivered by the Company and constitutes a valid
                 and legally binding agreement of the Company, enforceable in
                 accordance with its terms, subject, as to enforcement, to
                 applicable bankruptcy, insolvency, fraudulent transfer,
                 suspension of payments or other laws of general applicability
                 relating to or affecting creditors' rights and to general
                 equity principles;

                         (vi) The Company has been duly qualified as a foreign
                 corporation for the transaction of business and is in good
                 standing under the laws of each other


                                      -24-

                 jurisdiction in which it owns or leases properties or conducts
                 any business so as to require such qualification, or is subject
                 to no material liability or disability by reason of failure to
                 be so qualified in any such jurisdiction (such counsel being
                 entitled to rely in respect of the opinion in this clause upon
                 opinions of local counsel and in respect of matters of fact
                 upon certificates of officers of the Company, provided that
                 such counsel shall state that they believe that both you and
                 they are justified in relying upon such opinions and
                 certificates);

                          (vii) Each subsidiary of the Company has been duly
                 incorporated and is validly existing as a corporation in good
                 standing under the laws of its jurisdiction of incorporation;
                 and all of the issued shares of capital stock of each such
                 subsidiary have been duly and validly authorized and issued,
                 are fully paid and non-assessable, and (except for directors'
                 qualifying shares and except as otherwise set forth in the
                 Prospectus) are owned directly or indirectly by the Company,
                 free and clear of all liens, encumbrances, equities or claims
                 (such counsel being entitled to rely in respect of the opinion
                 in this clause upon opinions of local counsel and in respect of
                 matters of fact upon certificates of officers of the Company or
                 its subsidiaries, provided that such counsel shall state that
                 they believe that both you and they are justified in relying
                 upon such opinions and certificates);

                         (viii) The Company and its subsidiaries have good and
                 marketable title in fee simple to all real property owned by
                 them, in each case free and clear of all liens, encumbrances
                 and defects except such as are described in the Prospectus or
                 such as do not materially affect the value of such property and
                 do not interfere with the use made and proposed to be made of
                 such property by the Company and its subsidiaries; and any real
                 property and buildings held under lease by the Company and its
                 subsidiaries are held by them under valid, subsisting and
                 enforceable leases with such exceptions as are not material and
                 do not interfere with the use made and proposed to be made of
                 such property and buildings by the Company and its subsidiaries
                 (in giving the opinion in this clause, such counsel may state
                 that no examination of record titles for the purpose of such
                 opinion has been made, and that they are relying upon a general
                 review of the titles of the Company and its subsidiaries, upon
                 opinions of local counsel and abstracts, reports and policies
                 of title companies rendered or issued at or subsequent to the
                 time of acquisition of such property by the Company or its
                 subsidiaries, upon opinions of counsel to the lessors of such
                 property and, in respect of matters of fact, upon certificates
                 of officers of the Company or its subsidiaries, provided that
                 such counsel shall state that they believe that both you and
                 they are justified in relying upon such opinions, abstracts,
                 reports, policies and certificates);

                         (ix) To the best of such counsel's knowledge and other
                 than as set forth in the Prospectus, there are no legal or
                 governmental proceedings pending to which the Company or any of
                 its subsidiaries is a party or of which any property of the


                                      -25-

                 Company or any of its subsidiaries is the subject which, if
                 determined adversely to the Company or any of its subsidiaries,
                 would individually or in the aggregate have a material adverse
                 effect on the current or future consolidated financial
                 position, shareholders' equity or results of operations of the
                 Company and its subsidiaries; and, to the best of such
                 counsel's knowledge, no such proceedings are threatened or
                 contemplated by any Governmental Agency or threatened by
                 others;

                         (x) This Agreement has been duly authorized, executed
                 and delivered by the Company and, assuming that this Agreement
                 constitutes a valid and legally binding agreement of the
                 Company under New York law, this Agreement constitutes a valid
                 and legally binding agreement, enforceable in accordance with
                 its terms, subject, as to enforcement, to applicable
                 bankruptcy, insolvency, fraudulent transfer, suspension of
                 payments or other laws of general applicability relating to or
                 affecting creditors' rights and to general equity principles;

                 of this Agreement, each of the Spanish Underwriting Agreements,

                 contemplated will not result in a breach or violation of any of
                 the terms or provisions of, or constitute a default under any

                 which the Company or any of its subsidiaries, is a party or by
                 which the Company or any of its subsidiaries, is bound or to
                 which any of the property or assets of the Company or any of
                 its subsidiaries is subject, nor will such action result in any
                 violation of the provisions of the charter or Estatutos of the

                 with the Company or any of its subsidiary;

                         (xii) No Governmental Authorization of or with any
                 Governmental Agency in Spain having jurisdiction over the

                 other benefits, or sale proceeds with respect to shares of
                 capital stock (including the Shares) will require registration
                 thereof with the Spanish Registry of Foreign Investments; and

                 to be offered in the Global Offering will be required to be
                 registered with the Mercantile Registry;

                         (xiii) Insofar as matters of Spanish law are concerned,
                 the Registration Statement and the ADS Registration Statement
                 and the filing of such documents with the Commission have been
                 duly authorized by and on behalf of the Company; and the
                 Registration Statement and the ADS Registration Statement have
                 been duly executed pursuant to such authorization by and on
                 behalf of the Company;

                         (xiv) The statements in the Prospectus under

                 insofar as they purport to describe the provisions of the laws,

                 complete and fair;

                         (xv) In the opinion of Uria y Menendez, their opinions
                 set forth in the Prospectus under "Risk Factors-Risks Related
                 to this Offering-It may be difficult to enforce judgments
                 against us in U.S. courts" are confirmed as of such Time of

                 Shares or ADSs to the initial subscribers or purchasers,
                 respectively, thereof in the manner contemplated herein, or (C)
                 the deposit of International Shares with the Depositary against
                 the issuance of ADRs evidencing ADSs;

                         (xvii) The choice of law provisions set forth in
                 Section 18 hereof will be recognized by the Spanish courts; the
                 Company can sue and be sued in its own name; insofar as a New
                 York Court declares itself competent pursuant to the
                 irrevocable submission of the Company to the non-exclusive
                 jurisdiction of a New York Court, the Company may be sued in
                 such New York Court; the waiver by the Company of any objection
                 to the venue of a proceeding in a New York Court and the
                 agreement of the Company that this Agreement shall be governed
                 by and construed in accordance with the laws of New York are
                 legal, valid and binding; service of process effected in the
                 manner set forth in Section 16 hereof, assuming its validity
                 under New York law, will be effective; any judgment obtained in
                 a New York Court arising out of or in relation to the
                 obligations of the Company herein will be recognized in Spain
                 in accordance with and subject to the Ley de Enjuiciamiento
                 Civil (Law of Civil Procedure), the substantive provisions of
                 which are found in Articles 951 to 958, inclusive; the
                 aforementioned Articles provide, inter alia, that any judgment
                 rendered outside Spain may be enforced in Spain (A) if the
                 appropriate order (exequatur) would be obtainable according to
                 the provisions of any applicable treaty, (B) in the absence of
                 any such treaty, if it could be shown that the jurisdiction
                 where the foreign judgment was given would recognize Spanish
                 judgments on a reciprocal basis, provided that pursuant to the
                 case law of the jurisdiction in question such reciprocity has
                 not been denied, and (C) if the existence or non-existence of
                 reciprocity could not be proved, subject to the satisfaction of
                 certain conditions such as the defendant having entered a
                 personal appearance in the proceedings before the foreign
                 court; and since there is no treaty between Spain and the
                 United States, unless the conditions referred to in (C) above
                 were satisfied, in order to enforce in Spain a judgment of a
                 New York Court it would be necessary to prove that the New York
                 Courts would enforce judgments issued by Spanish courts;

                         (xviii) The Transaction Documents to which the Company
                 or any of its subsidiaries, as applicable, is a party have been
                 duly authorized, executed and delivered by the Company or its
                 subsidiaries, as applicable; each Transaction Document to which
                 the Company or any of its subsidiaries, is a party constitutes
                 a valid and binding agreement of the Company, or such
                 subsidiary, enforceable in accordance with its terms, subject,
                 as to enforcement, to applicable bankruptcy, insolvency,
                 fraudulent transfer, suspension of payments or other laws of
                 general applicability relating to or affecting the enforcement
                 of creditors' rights generally and to general equity
                 principles; by the date of this Agreement all required
                 corporate actions and Governmental Authorizations by the
                 Company or any of its subsidiaries, will have been taken or
                 obtained to effect and complete the Transactions including all
                 issuances, transfers, exchanges or acquisitions of capital
                 stock; and the Transactions

                 will have closed prior to the date of this Agreement and will
                 not result and have not resulted in the Company or any of its
                 subsidiaries, assuming or becoming subject to any material
                 obligation or liability not disclosed in the Prospectus;

                         (xix) The indemnification and contribution provisions
                 set forth in Section 9 hereof and the right of contribution
                 pursuant to Section 9(d) of the Act have been duly authorized
                 by the Company and constitute valid and binding obligations of
                 the Company enforceable in accordance with their terms,
                 subject, as to enforcement, to bankruptcy, insolvency,
                 fraudulent transfer, suspension of payments or other laws of
                 general applicability relating to or affecting creditors'
                 rights and to general equity principles;

                         (xx) All dividends and other distributions declared and
                 payable on the shares of capital stock may under current
                 Spanish laws and regulations be paid to the Depositary in euro
                 that may be converted into foreign currency that may be freely
                 transferred out of Spain, subject only to a withholding tax of
                 25% on the amount of any such payment in euro, but otherwise
                 free and clear of any other tax, duty, withholding or deduction
                 in Spain and without the necessity of obtaining any
                 Governmental Authorization of any nature whatsoever in Spain;

                         (xxi) Neither the Company nor any of its subsidiaries
                 is in violation of its Estatutos or in default in the
                 performance or observance of any material obligation,
                 agreement, covenant or condition contained in any Transaction
                 Document, indenture, mortgage, deed of trust, loan agreement,
                 acquisition, merger or joint venture agreement, lease or other
                 agreement or instrument to which it is a party or by which it
                 or any of its properties may be bound; and

                         (xxii) Although they do not assume any responsibility
                 for the accuracy, completeness or fairness of the statements
                 contained in the Registration Statement or the Prospectus,
                 except for those referred to in the opinion in subsection
                 (xiii) of this Section 7(d), such counsel have no reason to
                 believe that, as of the effective date of the Registration
                 Statement, either the Registration Statement or the Prospectus
                 (or, as of its date, any further amendment or supplement
                 thereto made by the Company prior to such Time of Payment)
                 (other than the financial statements and related schedules
                 therein, as to which such counsel need express no opinion)
                 contained an untrue statement of a material fact or omitted to
                 state a material fact required to be stated therein or
                 necessary to make the statements therein not misleading or
                 that, as of such Time of Payment, either the Registration
                 Statement or the Prospectus (or any such further amendment or
                 supplement thereto) (other than the financial statements and
                 related schedules therein, as to which such counsel need
                 express no opinion) contains an untrue statement of a material
                 fact or omits to state a material fact required to be stated
                 therein or necessary to make the statements therein, in light
                 of the circumstances under which they were made, not
                 misleading.

In giving the opinions specified in (X) and (Y) above, (I) Garrigues & Andersen
may rely without independent examination as to matters of United States federal
and New York law on the opinion of Sullivan & Cromwell, United States counsel
for the International Underwriters, described in paragraph (b) of this Section
7, and (II) Uria y Menendez may rely without independent investigation on the
opinion of Davis Polk & Wardwell, United States counsel for the Company
described in paragraph (c) of this Section 7, and as to matters of Argentine,
Brazilian, Chilean, Florida, Mexican and Peruvian law on the opinions of Baker &
McKenzie (Argentina), Machado Meyer, Sendacz & Opice (Brazil), Philippi,
Yrarrazaval, Pulido & Brunner (Chile), Greenberg Traurig (Florida), Baker &
McKenzie (Mexico) and Estudio Luis Echecopar Garcia (Peru) (the "foreign
counsel"), respectively; (III) Garrigues & Andersen and Uria y Menendez may: (A)
rely as to factual matters on certificates of directors and executive officers
of the Company and certificates of public officials and (B) state (1) that they
have not themselves checked the accuracy or completeness of, or otherwise
verified, the information furnished with respect to matters in the Registration
Statement or the Prospectus other than as specified above, but have generally
reviewed and discussed with representatives of the International Underwriters
and with certain officers and employees of, and United States and foreign
counsel and independent accountants for, the Company the relevant information
furnished, whether or not subject to their check and verification, and that
their opinion is rendered on the basis of such consideration, review and
discussion, but without independent check or verification, except as so
specified, and (2) that: (w) their opinion is subject to the effect of any
applicable bankruptcy, insolvency, reorganization, moratorium, or similar law
affecting creditors' rights generally and to public policy considerations; (x)
the term "enforceable" means that the obligations assumed by the relevant party
under the relevant documents are of a type that the Spanish courts would enforce
and it does not mean that those obligations will be necessarily enforced in all
circumstances in accordance with their terms; and (z) there is doubt as to the
enforceability in Spain of original actions or in actions for enforcement of
judgments of United States courts of liabilities predicated solely upon the Act,
provided that such counsel further states that, as of the date of such opinion,
they are not aware of any public policy considerations that would affect the
obligations of the relevant parties under the relevant documents or of any
circumstances under which such obligations would not be enforced in accordance
with their terms other than the fact that there is doubt as to the
enforceability in Spain of punitive damages and of original actions or actions
for enforcement of judgments of United States courts of liabilities predicated
solely upon the Act;

                  (e) Cristina Lamana, General Director of Legal Affairs of the
          Company, shall have furnished to you her written opinion, dated such
          Time of Payment, in form and substance satisfactory to you, to the
          effect that:

                         (i) The Company has been duly incorporated and is
                 validly existing as a corporation with limited liability

                         (ii) The Company and each of its subsidiaries have all
                 licenses, franchises, permits, authorizations, approvals and
                 orders of and from all governmental regulatory officials and
                 bodies that are necessary to own or lease and operate their
                 properties

                 subsidiaries taken as a whole;

                         (iii) To the best of her knowledge there are no legal
                 or governmental proceedings pending to which the Company or any
                 of its subsidiaries is a party or of which any property of the
                 Company or any of its subsidiaries is the subject which, if
                 determined adversely to the Company or any of its subsidiaries,
                 would individually or in the aggregate have a material adverse
                 effect on the consolidated financial position, shareholders'
                 equity or results of operations of the Company and its
                 subsidiaries; and, to the best of her knowledge, no such
                 proceedings are threatened or contemplated by any Governmental
                 Agency or threatened by others, except as disclosed in the
                 Prospectus;

                         (iv) The issue and sale of the International Shares and
                 ADSs, the deposit of the International Shares being deposited
                 with the Depositary against issuance of ADRs evidencing the

                 this Agreement, each of the Spanish Underwriting Agreements,

                 consummation of the transactions herein and therein
                 contemplated will not result in a breach or violation of any of
                 the terms or provisions of, or constitute a default under any
                 Transaction Document, indenture, mortgage, deed of trust, loan
                 agreement, acquisition, merger or joint venture agreement,
                 lease or other agreement or instrument known to such counsel to
                 which the Company or any of its subsidiaries is a party or by
                 which the Company or any of its subsidiaries is bound or to
                 which any of the property or assets of the Company or any of
                 its subsidiaries is subject, nor will such action result in any
                 violation of the provisions of the charter or Estatutos of the
                 Company or any of its subsidiaries or any statute or any order,
                 rule or regulation known to such counsel of any court or
                 Governmental Agency or body in Spain having jurisdiction over
                 the Company or any of its subsidiaries or any of its
                 properties;

                         (v) Each of Ole, Telefonica Servicios y Contenidos por

                 Infosel, Terra Networks Chile, Terra Networks Peru, Terra
                 Networks Argentina and Telefonica Interactiva USA
                 (collectively, the "Principal Subsidiaries") has been duly
                 incorporated and is validly existing as a corporation (sociedad
                 anonima) in good standing under the laws of Spain or: in the

                 shares of capital stock of each of the Principal Subsidiaries
                 have been

                 duly and validly authorized and issued and are fully paid and
                 nonassessable; and the Company owns the shares of capital stock
                 representing its participation in each of the respective
                 Principal Subsidiaries as set forth in the Prospectus, in each
                 case free and clear of all liens, encumbrances, equities and
                 claims;

                         (vi) The Transaction Documents to which the Company or
                 any of its subsidiaries is a party have been duly authorized,
                 executed and delivered by the Company and its subsidiaries;
                 each Transaction Document to which the Company or any of its
                 subsidiaries is a party constitutes a valid and legally binding
                 agreement of the Company or such subsidiary, enforceable in
                 accordance with its terms, subject, as to enforcement, to
                 applicable bankruptcy, insolvency, fraudulent transfer,
                 suspension of payments or other laws of general applicability
                 relating to or affecting the enforcement of creditors' rights
                 generally and to general equity principles; by the date of this
                 Agreement all required corporate actions and Governmental
                 Authorizations by the Company and its subsidiaries will have
                 been taken or obtained to effect and complete the Transactions,
                 including all issuances, transfers, exchanges or acquisitions
                 of capital stock; and the Transactions will have closed prior
                 to the date of this Agreement and will not result and have not
                 resulted in the Company or its subsidiaries assuming or
                 becoming subject to any material obligation or liability not
                 disclosed in the Prospectus;

                         (vii) Such counsel has no reason to believe that either
                 of the Spanish Folletos, and all amendments and supplements
                 thereto, did not conform in all material respects to the
                 requirements of Spanish law and the rules and regulations of
                 the CNMV or, as of their applicable effective or filing dates,
                 contained an untrue statement of a material fact or omitted to
                 state a material fact required to be stated therein or
                 necessary to make the statements therein, in light of the
                 circumstances under which they were made, not misleading; and

                         (viii) Nothing has come to such counsel's attention
                 that causes such counsel to believe that (A) either the
                 Registration Statement or the prospectus included therein
                 (except for the financial statements and related schedules
                 included therein, as to which such counsel need express no
                 belief), at the time the Registration Statement became
                 effective, contained an untrue statement of a material fact or
                 omitted to state a material fact required to be stated therein
                 or necessary to make the statements therein not misleading or
                 (B) the Prospectus (except as stated) as of its date and as of
                 the date of such opinion contained or contains an untrue
                 statement of a material fact or omitted or omits to state a
                 material fact necessary in order to make the statements
                 therein, in the light of the circumstances under which they
                 were made, not misleading.

In giving such opinion, such counsel may rely without independent examination as
to matters of Argentine, Brazilian, Chilean, Florida, Mexican and Peruvian law
on the opinions of foreign counsel for the Company

and at least three of the Representatives if any of the events in (i) through
(vi) above occurs after 3:00p.m. on the day on which the Public Deed is granted

have occurred or shall be occurring simultaneously therewith.

         8. The obligations of the International Underwriters hereunder as to

                 9. (a) The Company will indemnify and hold harmless each
International Underwriter against any losses, claims, damages or liabilities,
joint or several, to which such International Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement, the Prospectus, the Spanish
Folletos or the ADS Registration Statement, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse each
International Underwriter for any legal or other expenses reasonably incurred by
such International Underwriter in connection with investigating or defending any
such action or claim as such expenses are incurred; provided, however, that the
Company shall not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any untrue statement
or alleged untrue statement or omission or alleged omission made in any
Preliminary Prospectus, the Registration Statement, the Prospectus or the ADS


                                      -37-
<PAGE>   38
Registration Statement, or any such amendment or supplement, in reliance upon
and in conformity with written information furnished to the Company by any
International Underwriter through Goldman Sachs International expressly for use
therein.

                 (b) Each International Underwriter will indemnify and hold
harmless the Company against any losses, claims, damages or liabilities to which
the Company may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement, the Prospectus or the ADS Registration Statement, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement, the Prospectus or the ADS Registration
Statement, or any such amendment or supplement, in reliance upon and in
conformity with written information furnished to the Company by such
International Underwriter through Goldman Sachs International expressly for use
therein, and will reimburse the Company for any legal or other expenses
reasonably incurred by the Company as such expenses are incurred in connection
with investigating or defending any such action or claim.

                 (c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (which shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim, and (ii) does not include a
statement


                                      -38-
<PAGE>   39
as to or an admission of fault, culpability, or a failure to act by or on behalf
of any indemnified party.

                 (d) If the indemnification provided for in this Section 9 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the International
Underwriters on the other from the offering of the International Shares and
ADSs. If, however, the allocation provided by the immediately preceding sentence
is not permitted by applicable law or if the indemnified party failed to give
the notice required under subsection (c) above, then each indemnifying party
shall contribute to such amount paid or payable by such indemnified party in
such proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of the Company on the one hand and the International
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the International
Underwriters on the other shall be deemed to be in the same proportion as the
total net proceeds from the offering of International Shares and ADSs under this
Agreement (before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the International
Underwriters with respect to the International Shares subscribed for and ADSs
purchased under this Agreement. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand, or the
International Underwriters, on the other, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the International Underwriters agree that
it would not be just and equitable if contribution pursuant to this subsection
(d) were determined by pro rata allocation (even if the International
Underwriters were treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations
referred to above in this subsection (d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above in this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this subsection (d), no
International Underwriter shall be required to contribute any amount in excess
of the amount by which the total price at which the International Shares and
ADSs underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such International Underwriter has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to


                                      -39-
<PAGE>   40
contribution from any person who was not guilty of such fraudulent
misrepresentation. The International Underwriters' obligations in this
subsection (d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

                 (e) The obligations of the Company under this Section 9 shall
be in addition to any liability which the Company may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who controls
any International Underwriter within the meaning of the Act; and the obligations
of the International Underwriters under this Section 9 shall be in addition to
any liability which the respective International Underwriters may otherwise have
and shall extend, upon the same terms and conditions, to each officer and
director of the Company, to the Company's authorized representative in the
United States signing the Registration Statement and the ADS Registration
Statement and to each person, if any, who controls the Company within the
meaning of the Act.

                 10. (a) If any International Underwriter shall default in its
obligation to subscribe for the International Shares which it has agreed to
subscribe for hereunder at a Time of Payment, you may in your discretion arrange
for you or another party or other parties to subscribe for such International
Shares on the terms contained herein. If within 36 hours after such default by
any International Underwriter you do not arrange for the subscription for such
International Shares, then the Company shall be entitled to a further period of
36 hours within which to procure another party or other parties satisfactory to
you to subscribe for such International Shares on such terms. In the event that,
within the respective prescribed periods, you notify the Company that you have
so arranged for the subscription for such International Shares, or the Company
notifies you that it has so arranged for the subscription for such International
Shares, you or the Company shall have the right to postpone such Time of Payment
for a period of not more than seven days in order to effect whatever changes may
thereby be made necessary in the Registration Statement or the Prospectus, or in
any other documents or arrangements, and the Company agrees to file promptly any
amendments to the Registration Statement or the Prospectus which in your opinion
may thereby be made necessary. The term "International Underwriter" as used in
this Agreement shall include any person substituted under this Section with like
effect as if such person had originally been a party to this Agreement with
respect to such International Shares.

                 (b) If, after giving effect to any arrangements for the
subscription for the International Shares of a defaulting International
Underwriter or International Underwriters by you and the Company as provided in
subsection (a) above, the aggregate number of such International Shares which
remain unsubscribed does not exceed one-fifth of the aggregate number of all the
International Shares to be subscribed for at such Time of Payment, then the
Company shall have the right to require each non-defaulting International
Underwriter to subscribe for the number of International Shares which such
International Underwriter agreed to subscribe for hereunder at such Time of
Payment and, in addition, to require each non-defaulting International
Underwriter to subscribe for its pro rata share (based on the number of Firm
International Shares which such International Underwriter agreed to subscribe
for hereunder) of the International Shares of such defaulting International
Underwriter or International


                                      -40-
<PAGE>   41
Underwriters for which such arrangements have not been made; but nothing herein
shall relieve a defaulting International Underwriter from liability for its
default.

                 (c) If after giving effect to any arrangements for the
subscription for International Shares of a defaulting International Underwriter
or International Underwriters by you and the Company as provided in subsection
(a) above, the aggregate number of such International Shares which remains
unsubscribed exceeds one-fifth of the aggregate number of all the International
Shares to be subscribed at such Time of Payment or if the Company shall not
exercise the right described in subsection (b) above to require non-defaulting
International Underwriters to purchase International Shares of a defaulting
International Underwriter or International Underwriters, then this Agreement
(or, with respect to the Second Time of Payment, the obligations of the
International Underwriters to subscribe for and of the Company to sell the
Optional International Shares) shall thereupon terminate without liability on
the part of any non-defaulting International Underwriter or the Company, except
for the expenses to be borne by the Company and the International Underwriters,
as provided in Section 6 hereof, and the indemnity and contribution agreements
in Section 9 hereof; but nothing herein shall relieve a defaulting International
Underwriter from liability for its default.

                 11. The respective indemnities, agreements, representations,
warranties and other statements of the Company and the several International
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any International Underwriter or any controlling person
of any International Underwriter, or the Company, any officer or director or
controlling person of the Company, and shall survive delivery of and payment for
the International Shares and the ADSs hereunder.

                 12. If this Agreement shall be terminated pursuant to Section
10, the Company shall not then be under any liability to any International
Underwriter except as provided in Sections 6 and 9 hereof; but, if for any other
reason any Shares or ADSs are not delivered by or on behalf of the Company as
provided herein and in the Spanish Underwriting Agreements, the Company will
reimburse the International Underwriters through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the International Underwriters in making
preparations for the subscription, purchase, sale and delivery of the
International Shares and/or ADSs not so delivered, but the Company shall then be
under no further liability to any International Underwriter except as provided
in Sections 6 and 9 hereof.

                 13. In all dealings hereunder, you shall act on behalf of each
of the International Underwriters, and the parties hereto shall be entitled to
act and rely upon any statement, request, notice or agreement on behalf of any
International Underwriter made or given by you jointly or by Goldman Sachs
International.

                 All statements, requests, notices and agreements hereunder
shall be in writing, and if to the International Underwriters shall be
sufficient in all respects if delivered or sent by registered mail, telex or


                                      -41-
<PAGE>   42
facsimile transmission promptly confirmed by a writing delivered or sent by
registered mail, to Goldman Sachs International, Peterborough Court, 133 Fleet
Street, London EC4A 2BB, Attention: Equity Capital Markets; and if to the
Company, shall be sufficient in all respects if delivered or sent by registered
mail, telex or facsimile transmission promptly confirmed by a writing delivered
or sent by registered mail, to the Company at Via de las Dos Castillas, 33,
Complejo Atica, Edificio 1, 28224 Pozuelo de Alarcon, Spain, Attention: |X|
(Facsimile No. (34-91-452-|X|); provided, however, that any notice to an
International Underwriter pursuant to Section 9(c) hereof shall be delivered or
sent by mail, telex or facsimile transmission to such International Underwriter
at its address to be supplied by you to the Company upon request. Any such
statements, requests, notices or agreements shall take effect upon receipt
thereof.

                 14. This Agreement shall be binding upon, and inure solely to
the benefit of, the International Underwriters and the Company and, to the
extent provided in Sections 9 and 11 hereof, the officers and the directors of
the Company, the Company's authorized representative in the United States and
each person who controls the Company, or any International Underwriter, and
their respective heirs, executors, administrators, successors and assigns, and
no other person shall acquire or have any right under or by virtue of this
Agreement. No party subscribing for or purchasing any of the International
Shares or ADSs from any International Underwriter shall be deemed a successor or
assign by reason merely of such subscription or purchase.

                 15. Time shall be of the essence of this Agreement. The term
"Business Day", as used herein, shall mean any day on which banks in Madrid and
New York City, the AQS of the Spanish Stock Exchanges and NASDAQ are open for
business and when the Commission's office in Washington, D.C. is normally open
for business.

                 16. Each of the parties hereto irrevocably agrees that any
legal suit, action or proceeding against the Company brought by any
International Underwriter or by any person who controls any International
Underwriter arising out of or based upon this Agreement or the transactions
contemplated hereby may be instituted in any New York Court, irrevocably waives,
to the fullest extend it may effectively do so, any objection which it may now
or hereafter have to the laying of venue of any such proceeding, and irrevocably
submits to the nonexclusive jurisdiction of such New York Courts in any such
suit, action or proceeding. The Company has appointed CT Corporation System, New
York, New York, as its authorized agent (the "Authorized Agent") upon which
process may be served in any such action arising out of or based on this
Agreement or the transactions contemplated hereby which may be instituted in any
New York Court by any International Underwriter or by any person who controls
any International Underwriter, expressly consents to the jurisdiction of any
such court in respect of any such action, and waives any other requirements of
or objections to personal jurisdiction with respect thereto. Such appointment
shall be irrevocable. The Company represents and warrants that the Authorized
Agent has agreed to act as said agent for service of process, and the Company
agree to take any and all action, including the filing of any and all documents
and instruments, that may be necessary to continue such appointment in full
force and effect as aforesaid. Service of process upon the Authorized Agent and
written notice of such service to the Company shall be deemed, in every respect,
effective service of process upon the Company.


                                      -42-
<PAGE>   43
Notwithstanding the foregoing, any action based on this Agreement may be
instituted by any International Underwriter in any competent court in Spain.

                 17. In respect of any judgment or order given or made for any
amount due hereunder that is expressed and paid in a currency (the "judgment
currency") other than United States dollars, the Company, will indemnify each
International Underwriter against any loss incurred by such International
Underwriter as a result of any variation as between (i) the rate of exchange at
which the United States dollar amount is converted into the judgment currency
for the purpose of such judgment or order and (ii) the rate of exchange at which
an International Underwriter is able to purchase United States dollars with the
amount of the judgment currency actually received by such International
Underwriter on the Business Day immediately following receipt of the judgment
currency. The foregoing indemnity shall constitute a separate and independent
obligation of the Company and shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid. The term "rate of
exchange" shall include any premiums and costs of exchange payable in connection
with the purchase of or conversion into United States dollars.

                 18. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

                 19. This Agreement may be executed by any one or more of the
parties hereto in any number of counterparts, each of which shall be deemed to
be an original, but all such counterparts shall together constitute one and the
same instrument.

         If the foregoing is in accordance with your understanding, please sign
and return to us six counterparts hereof, and upon the acceptance hereof by you
on behalf of each of the International Underwriters, this letter and such
acceptance hereof shall constitute a binding agreement among each of the
International Underwriters and the Company. It is understood that your

Underwriters, the form of which shall be submitted to the Company for

              ARTHUR ANDERSEN Y CIA, S. COM. REGARDING THE COMPANY

                  Pursuant to Section 7(h) of the Underwriting Agreement, Arthur
Andersen y Cia, S. Com. shall furnish letters to the Underwriters to the effect
that:

                  (i) They are independent certified public accountants with
         respect to the Company and its subsidiaries within the meaning of the
         Act and the applicable published rules and regulations thereunder;

                  (ii) In their opinion, the consolidated financial statements
         and financial statement schedules audited by them and included in the
         Prospectus and the Registration Statement comply as to form in all
         material respects with the applicable accounting requirements of the
         Act and the related published rules and regulations thereunder;

                  (iii) The unaudited selected financial information with

         the Prospectus and the Registration Statement agrees with the
         corresponding amounts in the audited consolidated financial statements
         for such three fiscal years and the six month period;

                  (iv) On the basis of limited procedures, not constituting an
         examination in accordance with Spanish generally accepted auditing
         standards, consisting of a reading of the unaudited financial

         and accounting matters and such other inquiries and procedures as may

                  which the Prospectus and the Registration Statement disclose
                  have occurred or may occur or which are described in such
                  letter; and

                           (C) for the period from June 30, 1999 to September

                  increases which the Prospectus and the Registration Statement
                  disclose have occurred or may occur or which are described in
                  such letter; and

                  included in the Registration Statement and Prospectus do not
                  comply as to form in all material respects with the applicable
                  accounting requirements of the Act and the published rules and
                  regulations thereunder or the pro forma adjustments have not
                  been properly applied to the historical amounts in the

         included in the Prospectus and the Registration Statement and the
         limited procedures, inspection of minute books, inquiries and other
         procedures referred to in paragraph (iv) above, they have carried out
         certain specified procedures, not constituting an examination in
         accordance with generally accepted auditing standards in Spain, with
         respect to certain amounts, percentages and financial information
         specified by the Representatives, which are derived from the general
         accounting records of the Company and its subsidiaries, which appear in
         the Prospectus, or in Part II of, or in exhibits and schedules to, the
         Registration Statement specified by the Representatives, and have
         compared certain of such amounts, percentages and financial information
         with the accounting records of the Company and its subsidiaries and
         have found them to be in agreement.

International Underwriters (the "International Underwriters"), have entered into
an International Underwriting Agreement (the "International Underwriting

American depositary receipts ("ADRs"), of the Company, pursuant to the
Registration Statement and the Prospectus. Capitalized terms used herein and not
otherwise defined shall have the meanings set forth in the International
Underwriting Agreement. In addition, the undersigned understands that the
Company is concurrently entering into a Spanish retail underwriting agreement
and a Spanish institutional underwriting agreement with certain Spanish
underwriters providing for the sale by the Company of shares to institutional
investors in Spain and to retail investors in Spain, the European Economic Area
and Andorra.

         In consideration of the International Underwriters' agreement to

such substantially similar securities, without the prior written consent of the
Representatives.

         The foregoing restriction is expressly agreed to preclude the
undersigned from engaging in any hedging or other transaction which is designed
to or which reasonably could be expected to lead to or result in a sale or
disposition of the undersigned's Shares, even if such Shares would be disposed
of by someone other than the undersigned. Such prohibited hedging or other
transaction would include without limitation any short sale or any purchase,
sale or grant of any right (including without limitation any put or call option)
with respect to any of the undersigned's Shares or with respect to any security
that includes, relates to, or derives any significant part of its value from
such Shares.

         In furtherance of the foregoing, the Company, and any duly appointed
transfer agent for the registration or transfer of the securities described
herein, are hereby authorized to decline to make any transfer of securities if
such transfer would constitute a violation or breach of this Letter Agreement.

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to enter into this Letter Agreement. All authority
herein conferred or agreed to be conferred and any obligations of the
undersigned shall be binding upon the successors, assigns, heirs or personal
representatives of the undersigned.

Agreement does not become effective, or if the International Underwriting
Agreement (other than the provisions thereof which survive termination) shall
terminate or be terminated prior to payment for and delivery of the Shares to be
sold thereunder, the undersigned shall be released from all obligations under
this Letter Agreement.

         The undersigned understands that the International Underwriters are
entering into the International Underwriting Agreement and proceeding with the
International Offering in reliance upon this Letter Agreement.

Ladies and Gentlemen:

         The undersigned understands that you, as representatives of the several
International Underwriters (the "International Underwriters"), have entered into
an International Underwriting Agreement (the "International Underwriting
Agreement") with Terra Networks, S.A., a corporation with limited liability
(sociedad anonima) organized under the laws of Spain (the "Company") providing
for the international offering (the "International Offering") by the several
International Underwriters named in Schedule I to the International Underwriting
Agreement, of ordinary shares, nominal value (U)2.00 each (the "Shares"),

American depositary receipts ("ADRs"), of the Company, pursuant to the
Registration Statement and the Prospectus. Capitalized terms used herein and not
otherwise defined shall have the meanings set forth in the International
Underwriting Agreement. In addition, the undersigned understands that the
Company is concurrently entering into a Spanish retail underwriting agreement
and a Spanish institutional underwriting agreement with certain Spanish
underwriters providing for the sale by the Company of shares to institutional
investors in Spain and to retail investors in Spain, the European Economic Area
and Andorra.

         In consideration of the International Underwriters' agreement to
purchase and make the International Offering of the Shares and ADSs, and for
other good and valuable consideration receipt of which is hereby acknowledged,
the undersigned hereby agrees that, without the prior written consent of the
Representatives on behalf of the International Underwriters, the undersigned

dispose of any securities of the Company that are substantially similar to the
Shares or ADSs, including but not limited to any securities that are convertible
into or exchangeable for, or that represent the right to receive capital stock
or any such substantially similar securities, without the prior written consent
of the Representatives. The undersigned further agrees that during the period
between 180 days and one year after the date the Shares are admitted to trading
on the Madrid Stock Exchange, it will not issue, offer, sell, contract to sell
or otherwise dispose of more than 25% of the shares of the Company that it
acquires under the Share Option Agreement dated October 5, 1999 between the
undersigned and Telefonica, S.A. without the prior written consent of the
Representatives.

         The foregoing restriction is expressly agreed to preclude the
undersigned from engaging in any hedging or other transaction which is designed
to or which reasonably could be expected to lead to or result in a sale or
disposition of the undersigned's Shares, even if such Shares would be disposed
of by someone other than the undersigned. Such prohibited hedging or other
transaction would include without limitation any short sale or any purchase,
sale or grant of any right (including without limitation any put or call option)
with respect to any of the undersigned's Shares or with respect to any security
that includes, relates to, or derives any significant part of its value from
such Shares.

         In furtherance of the foregoing, the Company, and any duly appointed
transfer agent for the registration or transfer of the securities described
herein, are hereby authorized to decline to make any transfer of securities if
such transfer would constitute a violation or breach of this Letter Agreement.

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to enter into this Letter Agreement. All authority
herein conferred or agreed to be conferred and any obligations of the
undersigned shall be binding upon the successors, assigns, heirs or personal
representatives of the undersigned.

         The undersigned understands that, if the International Underwriting
Agreement does not become effective, or if the International Underwriting
Agreement (other than the provisions thereof which survive termination) shall
terminate or be terminated prior to payment for and delivery of the Shares to be
sold thereunder, the undersigned shall be released from all obligations under
this Letter Agreement.

         The undersigned understands that the International Underwriters are
entering into the International Underwriting Agreement and proceeding with the
International Offering in reliance upon this Letter Agreement.

                 TRANSFER OF SHARES OF INFOVIA, SOCIEDAD ANONIMA

WE: (a) INFOVIA INTERNATIONAL INC., [   ] hereinafter known as the "SELLER,"
[   ] (b) INFOVIA, SOCIEDAD ANONIMA, a corporation formed, organized and
existing under the laws of the Republic of Guatemala, domiciled in Guatemala
City, hereinafter known as the "COMPANY," [   ] and (d) TELEFONICA INTERACTIVA,
SOCIEDAD ANONIMA, a corporation formed, organized and existing under the laws of
Spain, domiciled in the city of Madrid, Spain, represented by its President with
sufficient powers of legal representation for this document, Juan Perea Saenz de

The SELLER wishes to transfer to the BUYER, fifty-seven shares, equal to
ninety-five percent (95%) of the shares into which it is divided and represents
the subscribed and paid-in capital of the COMPANY, (hereafter, the "Shares").

iv.   WHEREAS,

The BUYER wishes to acquire from the SELLER, all of the Shares, free of any
liability, contingent, encumbrance, debt, levy, tax, claim, interest,
litigation, obligation, civil complaint, criminal complaint, process,
proceedings, restriction, limitation, appropriation, lien, pledge, embargo,
request, condition precedent, condition subsequent and/or rights of third
parties of any kind (collectively and for purposes of this contract,
"Encumbrance") incumbent on the COMPANY or the SELLER, as the prior owner of the
Shares, prior to today's date, July twenty-one, nineteen hundred ninety-nine,
and, therefore, the BUYER assumes no Encumbrance, restriction, etc., with regard
to the Shares.

THEREFORE,

The parties hereby consent to enter into a share transfer and endorsement
contract, which will be governed by the following clauses and conventions:

CLAUSE ONE: The following declarations, authorizations, representations,
assertions, promises and guarantees that herein the COMPANY and SELLER formally,
expressly and irrevocably give and make in regard to the interests of each, are,
as of this day, complete, precise, exact and truthful, and their effects should
be maintained and extended over time, and, in the event that they are not, the
SELLER agrees to indemnify the BUYER pursuant to Clause Five of this instrument.
The SELLER and the COMPANY respectively, and jointly, as the case may be,
represent and warrant individually and collectively the following:

I.    Legal capacity: The SELLER and COMPANY may legally acquire the rights and
      assume the obligations derived from this agreement. The persons appearing
      herein and representing the SELLER and the COMPANY have sufficient legal
      capacity, powers and authority to appear, authorize and undertake, in the
      capacity in which they are acting, the obligations acquired by their
      principals because of this document. The COMPANY is a corporation
      organized and existing under the laws of Guatemala with legal capacity to
      be unconditional owner of all its assets; it is duly authorized and has
      all authorizations, permits, licenses and industrial property rights,
      etc., and they are completely valid, as conferred by law, for conducting
      its business in any jurisdiction in which it holds or uses its assets or
      does business and for legally carrying out its corporate purpose,
      including but not limited to providing services in the telecommunications
      and teleinformation industry (the "Business").

II.   No liability: Neither the BUYER, as the future owner of the Shares, nor
      the COMPANY will be liable to third parties for any encumbrance,
      restriction, etc., incumbent on the COMPANY prior to today's date, that is
      not reflected and contained in the FINANCIAL STATEMENTS of the COMPANY,
      which are incorporated into this agreement as EXHIBIT 1, and in the event
      that any expenditure is necessary in regard to any encumbrance,
      restriction, etc., the SELLER will be exclusively liable for this
      obligation. The provisions of this number are complemented by the
      provisions of Clause Five of this instrument.

<PAGE>   3

III.  Lack of restrictions: There are no options, promises or commitments of any
      kind, either oral or written, conferred by the SELLER on the Shares, and
      neither the COMPANY nor the SELLER has any other oral or written agreement
      that gives any other person or entity a right to acquire shares or options
      in order to acquire the Shares or other shares of the COMPANY. All the
      Shares were acquired through completely legal transactions in observance
      of applicable legal provisions and they are not subject to any condition
      subsequent in terms of control. At the same time, there are no guarantees,
      agreements, conventions, contracts, commitments, requests or claims of any
      kind, pending or threatened, in which the COMPANY is involved or in which
      the SELLER has limited the transfer and endorsement of the Shares, or that
      affects the transfer and endorsement of the Shares in any way.

IV.   Capital, right of ownership and right of sale: The SELLER is the owner,
      with equal capacity, of all the shares that are the subject of this
      agreement. The authorized, subscribed and paid-in capital of the COMPANY
      is that previously indicated. All shares are fully paid-in and have been
      legally issued pursuant to applicable Guatemalan law. The SELLER has the
      right of full ownership over all the Shares, which are completely free of
      Encumbrances, and the SELLER has the unrestricted right to sell, endorse
      and transfer all the Shares and has, moreover, full and unrestricted title
      to them, and will transfer to the BUYER legal and negotiable title to the
      Shares of the COMPANY, unrestricted and unencumbered.

V.    Unrestricted ownership: The COMPANY is the unrestricted holder and owner
      with full title, and in accordance with the law, of all its property and
      goods comprising its assets, including but not limited to all that are
      listed in the FINANCIAL STATEMENTS previously mentioned. At the same time,
      the assets of the COMPANY are completely free of Encumbrances except those
      reflected and contained in the aforementioned FINANCIAL STATEMENTS of the
      COMPANY, and it is duly authorized to own its property and assets and to
      develop the Business and corporate purpose in the manner in which it does
      so today and expects to do in the future.

VI.   Financial statements: A copy signed by the parties of the Financial
      Statements of the COMPANY, as of June thirty, nineteen hundred
      ninety-nine, hereinafter known as the "FINANCIAL STATEMENTS," is an
      integral part of this agreement as EXHIBIT 1. The FINANCIAL STATEMENTS
      include the Balance Sheet as of June 30, nineteen hundred ninety-nine,
      Income Statement and Notes to the financial statements, which are correct
      and complete and have been prepared in accordance with accounting
      principles generally accepted in Guatemala, using a base consistent with
      prior years that provides a true and complete statement, as of this date,
      of the financial condition of the COMPANY and its operations. The
      FINANCIAL STATEMENTS faithfully reflect the assets, liabilities, worth,
      operations, revenues, expenses, earnings, contingencies, accounts and
      other items of the financial statements of the COMPANY, as of the closing
      date, with no material omissions or defects in the accounting that could
      adversely affect the properties, business, operations, earnings, assets,
      goods, contingencies, obligations or the financial condition of the
      COMPANY, its assets or any other account of the FINANCIAL STATEMENTS. As
      of the closing date of the Financial Statements to today's date, there has
      been no change in the financial condition of the COMPANY or of the SELLER
      that could have a negative impact on the financial condition of the
      COMPANY.

VII.  Condition of the COMPANY'S assets. The COMPANY'S equipment, which forms a
      part of the assets of the COMPANY is in perfect condition, well maintained
      and in working order, and fit for use to carry out the activities and
      business of the COMPANY, save for normal wear and tear caused by the
      passage of time.

<PAGE>   4

VIII. No breach of contract resulting from the COMPANY'S contracts. Neither the
      COMPANY nor the SELLER nor third parties with whom they have contractual
      ties have breached the terms and conditions in favor of the COMPANY in
      such a way as to raise the possibility or threat of any lawsuit, civil
      complaint, criminal complaint, proceedings or liability for the COMPANY
      and/or its assets.

IX.   No breach of contract resulting from the SELLER'S contracts. Neither the
      SELLER nor third parties with whom it has contractual ties have breached
      the terms and conditions of the contracts in such a way as to raise the
      possibility or threat of any lawsuit, civil complaint, criminal complaint,
      proceedings or liability that could affect the Shares and/or their
      transfer or endorsement as contemplated in this agreement and its
      validity.

X.    No breach of contract: The COMPANY and the SELLER have paid, inclusive as
      of this date, all principle and interest with regard to their debts,
      obligations, taxes and liabilities, or of any contract or agreement that
      might carry with it the possibility or threat of any lawsuit, complaint,
      accusation, procedure or liability that might affect the COMPANY and/or
      its assets.

XI.   Taxes: The COMPANY has submitted, without fail, all tax returns required
      by law, and it has paid, without fail or any objection, all taxes, levies
      and assessments of a federal, departmental and municipal nature that are

      returns or any levy, reclassification or request for taxes, moreover, it
      has withheld and paid all taxes and sums as required by law, with regard
      to any sum paid or incurred in favor of all its employees, contractors,
      creditors, shareholders or any third party and neither the COMPANY nor the
      SELLER knows of any obligation, levy, tax, request, reclassification or
      adjustment with regard to periods covered by returns or communications
      submitted before today inclusive, beyond those that appear on such returns
      or communications. There is no audit, request, bill of indictment or any
      other claim pending against the COMPANY. Neither the COMPANY nor the
      SELLER have been notified by competent authorities of any defect, error or
      reclassification of its tax and/or any other obligation. The COMPANY will
      be liable for payment of Income Tax and the Tax on Commercial and
      Agricultural Enterprises for the fiscal period ending June thirty,
      nineteen hundred ninety-nine.

XII.  Intermediaries and commission agents: The parties to this contract state
      that they have not contracted for the services of any intermediary, broker
      or commission agent, therefore, neither the COMPANY nor the BUYER will be
      responsible for payment of fees, commissions or compensation of any kind,
      for services as an intermediary, broker or commission agent or any other
      kind for the transfer and endorsement of the Shares.

XIII. Labor contracts: The COMPANY is in compliance with all laws, regulations
      and other provisions or rules with regard to employment and social
      security. It has likewise complied with all obligations and requirements
      that as an employer are required by Guatemalan law for its workers. There
      is no union in the COMPANY; nor is it involved in illegal labor practices,
      and the SELLER knows of no labor or union campaign or movement within the
      COMPANY or any threat of such. Neither is there a threat of any strike
      that could affect the normal operations and/or Business of the COMPANY.

XIV.  In compliance with the Law: The COMPANY is in compliance with all laws,
      regulations, decrees, provisions and/or contracts, including without
      restriction on the general nature of the foregoing, any provision, rule,
      temporary article, clause and/or convention related to any part of the
      assets of the COMPANY, and likewise in terms of what the SELLER has done
      with regard to the Shares.

<PAGE>   5

      Neither the COMPANY nor the SELLER has reason to believe that any
      authority will file a complaint that the COMPANY and/or the SELLER has
      violated any law, regulation, decree or provision, rule and/or contract
      that affects the COMPANY in any way or its assets, financial statements,
      Business or the Shares. There is no legal action pending or imminent, and
      neither the COMPANY nor the SELLER knows of any threat or has reason to
      believe that anyone is going to initiate legal action in order to cancel,
      suspend or revoke any authorization, permit, license or industrial
      property right, as such terms are subsequently defined, which have been
      issued to the COMPANY for the conduct of its business or to the SELLER
      with regard to the Shares of the COMPANY that it owns. This agreement for
      the transfer and endorsement of the Shares of the COMPANY, which are the
      property of the SELLER, does not violate in whole or in part any law,
      regulation, decree, provision, rule and/or contract that includes the
      cancellation, suspension or revocation of any authorization, permit,
      license or industrial property right that in any way would benefit or be
      necessary to the conduct of the business of the COMPANY.

XV.   No outstanding litigation against the COMPANY: Neither the COMPANY nor the
      SELLER is aware of the existence of any claim against the COMPANY or
      initiated or instituted for it before any judge or court nor before any
      arbitrator or entity, commission, governmental office or agency or of any
      kind, national or foreign, of civil, penal, labor, environmental actions
      or of any other kind, lawsuits, administrative proceedings, arbitration or
      investigations of any authority, that are pending, imminent or threatened,
      that could affect the COMPANY in any way, or its assets or the Shares. The
      COMPANY has made ample provisions for dealing with future adverse results
      in accordance with the rules and principles of accounting generally
      accepted in Guatemala and with sound business practices.

XVI.  Other contracts and guarantees: Neither the COMPANY nor the SELLER is
      committed or obligated to any contract, convention or agreement of any
      kind, oral or written, that affects or could affect the COMPANY and its
      assets or the Shares. Neither the COMPANY nor the SELLER has issued
      guarantees or bonds of any kind that are not reflected and contained in
      the COMPANY'S Financial Statements. The SELLER represents and warrants
      that the COMPANY is not in breach of any agreement or contract related to
      its assets, Business or operations and as far as the SELLER knows, after
      thorough investigation, no event has occurred that over the course of time
      or with service of process, or with both, could result in an action for
      breach of contract by any of the parties to such agreements or contracts.
      All of the COMPANY'S present contracts are in full force and are legal and
      binding on the parties.

XVII. Taxes on goods comprising the COMPANY'S assets. The goods and services
      comprising the COMPANY'S assets are current with regard to payment of
      sales taxes, import taxes, federal taxes, municipal taxes and/or levies,
      as well as any other tax, levy or fee that could affect them.

XVIII. Ownership rights over the COMPANY'S assets: There are no third parties
      that are threatening or disputing the COMPANY as to the right of
      ownership, possession, use, retention and full enjoyment of the goods
      comprising its assets, and they are completely free of Encumbrances and
      ownership of any other kind that are not reflected and contained in the
      aforementioned FINANCIAL STATEMENTS of the COMPANY. The Government of the
      Republic of Guatemala has not initiated nor threatens to take measures
      toward partial or total expropriation that could affect the assets of the
      COMPANY, and neither the COMPANY nor the SELLER knows of any measure or
      threat in that regard nor has reason to believe that any measure or threat
      exists.

XIX.  No existing restrictions on the COMPANY'S assets: Neither the COMPANY nor
      the SELLER is committed or obligated by any contract, convention or
      agreement of any kind, oral or written, that affects or could affect the
      assets of the COMPANY, and the COMPANY and the SELLER have not issued
      guarantees or bonds of any kind that affect or could affect the assets of
      the COMPANY and that are not reflected and contained in the aforementioned
      Financial Statements of the COMPANY. There are no options of any kind
      granted by the COMPANY, nor guarantees, agreements, contract, requests,
      commitments, promises or complaints of any kind pending or threatened, in
      which the COMPANY is involved with regard to its assets, or that affects
      them or could affect them, so that there is no condition or restriction
      that prevents the authorization and signing of the relevant documents to
      carry out the transfer and endorsement of the Shares.

XX.   Eviction, clearing of title and free exercise: The SELLER warrants to the
      BUYER the free exercise of property rights over the Shares, free of
      Encumbrances, as well as over the assets of the COMPANY. Therefore, in the
      event that the BUYER has concerns about the free, full and total exercise
      of property rights that will be transmitted to it or the existence of this
      appears threatened, or the BUYER is concerned about the possession, use,
      retention and full enjoyment of the Shares it will acquire from the SELLER
      and/or anything related to the assets of the COMPANY, the SELLER, at its
      own expense and its exclusive risk, will defend the property rights
      transmitted by it, as well as the possession, use, retention and full
      enjoyment of the Shares and the assets of the COMPANY, warrants and
      defenses that are extended to each and every judicial and administrative
      proceeding as required. Should the defense be ineffective, the SELLER will
      proceed to the required clearing of title, indemnification and payment of
      damages and losses, the foregoing to the entire satisfaction of the BUYER,
      provided that they originate from acts, incidents or events prior to
      today's date, or that if they are in the future, they are directly related
      to acts, incidents or events that occurred prior to today's date.

      properties, business activities, operations, earnings, assets, obligations
      or the financial condition of the COMPANY.

XXV.  Portfolio and provisions: The SELLER represents and warrants that the
      portfolio and other accounts receivable of the COMPANY: (i) are duly
      recorded, evaluated and provided for in the respective amounts, in

      obligations on the respective debtors and are not subject to compensation
      or counterclaim; (iv) they do not represent obligations for goods

      restrictions. The COMPANY has made appropriate provisions for the
      protection of its inventory, in accordance with the accounting rules and
      principles applicable to the COMPANY in the Republic of Guatemala, and
      such inventory is fit for use or sale by the COMPANY within the ordinary
      course of its Business. With regard to the inventory, there are no
      obligations incumbent on the COMPANY.

      conduct its Business in all jurisdictions in which it owns and uses its
      assets or performs its Business and to legally carry out its corporate
      purpose (collectively "Licenses," the use of this term throughout the
      contract does not imply a limitation under the prior definition, since any
      other authorizations should be understood to be included, even though they
      are not expressly mentioned, they are requisites legally necessary for the
      performance of the Business of the COMPANY). Registration Licenses are in
      full force and effect. A list of Licenses is attached to this contract as
      EXHIBIT 2. The COMPANY has paid all required sums to the respective

      and conditions of the Licenses, and the COMPANY has not been investigated
      or penalized by the respective administrative authorities, on account of
      the use of the Licenses and the provision of services of its Business.
      There is no conduct or behavior of the COMPANY or SELLER in the use of the
      Licenses and in the provision of services of its Business that could give
      rise to the imposition of penalties on the COMPANY, and there is no
      administrative proceeding in progress with the respective administrative
      authority that has as its purpose or could result in the imposition of
      fines, sanctions, penalties or restrictions on the COMPANY with regard to
      the use of the Licenses. The Licenses are sufficient for the COMPANY to
      carry out its Business in the way it does at the present time.

      assertions, promises and guarantees stated in prior numbers do not
      restrict or exclude others that, while not being expressly indicated, are

<PAGE>   9

documentary evidence) or in writing to the BUYER by the SELLER, and the COMPANY
with regard to the latter, to its assets, to the Shares, and because the
declarations, authorizations, representations, assertions, promises and
guarantees given and made by the SELLER and the COMPANY are truthful, valid,
correct, reliable and complete, the SELLER hereby transfers and endorses free of
Encumbrances to the BUYER, and the BUYER accepts all the Shares that are the

      The aforementioned value or price is net price, therefore, it will be free
      of any tax, charge, levy or assessment ("Taxes") that could be applicable,
      in which case, should there be any Tax, it will be paid by the BUYER.

      The transfer of Shares contained in this document is subject to the actual

<PAGE>   10

thus exercising, as of today's date, all its rights including corporate and

therefore, the Transfer and Endorsement of its Shares, with all their terms and
stipulations, thus, the BUYER will sign the corresponding notice addressed to
the COMPANY.

CLAUSE FIVE: Guarantee. [   ] hereby acts as unlimited and unconditional
guarantor of the BUYER, a guarantee that will remain in effect for a period of
five years counting from today's date. The purpose of this guarantee is to cover
the Encumbrances that could occur as a consequence or result of any Event of
Indemnification, even though the action, litigation or penalty may be initiated
after today's date. For purposes of this agreement "Events of Indemnification"
means (a) any inaccuracy, error, omission or breach of any of the declarations,
authorizations, assertions, representations, promises and guarantees made or
given by the SELLER and the COMPANY in this agreement, whether or not said
inaccuracy, error, omission or breach was known by the Indemnified Parties (as
will be subsequently defined in this same clause) before today's date and that
could produce adverse results; (b) the losses, expenses, costs, indemnification
or expenditure of any kind incurred by the Indemnified Parties (as will be
subsequently defined in this same clause), as a result of the existence of
concealed or contingent liabilities that are not recorded or provided for in the
Financial Statements in precise, exact or adequate form, or that have been
recorded or provided for at a lower value than the liabilities or contingencies
actually are; (c) the value of the obligations for payment of taxes, levies,
assessments, interest in arrears, penalties, fines, charges or adjustments that
were not sufficiently reflected or provided for in the Financial Statements or
on the books and records of the COMPANY; (d) the losses suffered by the
Indemnified Parties (as will be subsequently defined in this same clause)
resulting from the failure to reflect assets in the Financial Statements or on
the books and records of the COMPANY, including the nonexistence of customers of
the COMPANY as listed in EXHIBIT 4, which forms an integral part of this
agreement; (e) the losses suffered by the COMPANY resulting from the existence
of liabilities not reflected in the Financial Statements; (f) the losses,
expenses, costs, expenditures or indemnification incurred by the COMPANY as a
consequence of the COMPANY having failed to comply with any contract, agreement,
pact, law, decree, judgment, writ, decision or regulation that obliges the
COMPANY and any other party not listed here and that directly affects the
interests of the BUYER or the assets, goods, Licenses or Financial Statements of
the COMPANY for events or actions undertaken or occurring up to or before
today's date; and (g) the occurrence of any event that implies the use or
application of the "Objective Standard" defined in Clause Seven of this
agreement. In the aforementioned events:

The SELLER agrees to indemnify the BUYER and the COMPANY, its directors,
employees, shareholders, agents and advisers (collectively the "Indemnified
Parties") and maintain them indemnified against any cost, expense, loss, claim,
action, complaint, litigation, penalty, fine, injury or expenditure incurred or
created, as a consequence or result of any Encumbrance or loss suffered as a
result of an "Event of Indemnification." In the event that the guarantee issued
by [   ] is insufficient, the SELLER promises and agrees to immediately pay
without protest to the BUYER, in cash and in dollars, legal tender of the United
States of America, the resulting sum of money, and the BUYER will initiate the
appropriate legal action in order to claim payment from the SELLER.

In the event of any claim that constitutes an Event of Indemnification, the
BUYER will have the right, at its sole and absolute discretion, to immediately
collect any amount resulting from the Event of Indemnification of the guarantee
with a notice by the BUYER to [   ], listing the amount of the claim, and, at
the same time, [   ] will have no opportunity of any kind to reserve [a right]
or [make a] claim or defense. The BUYER will subrogate all rights related to the
Event of Indemnification to [   ], if applicable. The foregoing obligation on
the part of [   ] and the SELLER, whatever the case may be, are irrevocable
obligations under this agreement. Notwithstanding that, in the event of
collection

<PAGE>   11

of the guarantee by the BUYER, if the SELLER does not agree with the payment
made by [   ], it may follow the procedure contained in the Resolution of
Conflicts Clause of this agreement.

CLAUSE SIX: Reliability of the information furnished to the BUYER: The SELLER
agrees that the BUYER, in order to enter into this business and consent to this
agreement, has relied on all the declarations, authorizations, assertions,
representations, promises and guarantees made by the SELLER and the COMPANY,
according to this agreement and its EXHIBITS; all the information supplied
orally (with some supporting document) or in writing by the SELLER and the
COMPANY, regarding the latter, its assets, the Shares of the SELLER in the
COMPANY; and in addition on other stipulations contained in this agreement.
Therefore, if:

i. Said declarations, authorizations, assertions, representations, promises,
guarantees and information are incorrect or incomplete, in whole or in part,
and/or

ii. Any claim affecting the COMPANY, its assets and/or the shares of the
COMPANY, but not limited to that indicated in this agreement, were to be
established;

the BUYER will have the right, in addition to using other resources due to it
under this agreement and the law, to claim enforcement of the guarantee referred
to in Clause Five above. The SELLER promises and agrees to immediately pay
without protest to the BUYER, in cash and in dollars, legal tender of the United
States of America, the resulting sum of money, and the BUYER will initiate the
appropriate legal action in order to claim payment from the SELLER, if
necessary.

CLAUSE SEVEN: "Objective Standard." For purposes of this agreement, any
reference herein to: "negative impact, adverse results, adverse effect,
adversely affect," and other similar terms, will be interpreted as the existence
of a reduction of five percent (5%) from the Company and Business Plan as of
April 1999, with gross income of two million fifty-two thousand eight hundred
twenty four dollars (US$2,052,824), legal tender of the United States of
America, equal to the sum of thirteen million five hundred forty-nine thousand
six hundred eighty-three quetzals (Q13,549,683.87), at an exchange rate of six
point six zero zero five quetzals (Q6.6005) to the dollar (US$1.00), legal
tender of the United States of America, therefore, in any case, the amount
expressed in quetzals and thus converted to dollars at the rate of exchange
indicated, will always be the parameter for application of the "Objective
Standard," notwithstanding any fluctuation above or below the rate of exchange
for the quetzal with the dollar, legal tender of the United States of America.
Likewise, this "Objective Standard" is also considered to be a reduction of
percent (5%) in any of the categories of active customers of the COMPANY, which
appear in EXHIBIT 4, which forms an integral part of this agreement. This is
considered the "Objective Standard" for interpretation of such terms in the
clauses of this agreement, unless otherwise stipulated between the BUYER and the
SELLER.

CLAUSE EIGHT: BUYER'S declaration. The BUYER may legally acquire the rights and
assume the obligations derived from this agreement. The person appearing herein
to represent the BUYER has sufficient legal capacity, powers and authority to
appear, authorize and assume, acting in this capacity, the obligations acquired
by the BUYER by virtue of this agreement.

<PAGE>   12

CLAUSE NINE: Amendments: The parties expressly accept that this agreement
represents the complete and reliable form in which they wish to consent to the
terms of the share transfer and endorsement contract, and that therefore it may
not be modified either presumptively or tacitly on account of the sporadic or
repeated conduct of one of the parties, on account of tolerance by one of the
parties amid a breach by the other or for any other reason. Thus, this agreement
may not be altered, modified, revised or amended except by written consent of
the parties to the contract.

CLAUSE TEN: Tolerance: The potential tolerance of the BUYER as to exercising its
rights pursuant to this agreement or to any document EXHIBIT or result of all of

within sixty days from today, in the equivalent in domestic current at the
dollar exchange rate in effect on the date of actual payment. This price shall
accrue interest at 8% per annum between today and the actual payment date. In
the event of delay in payment, the maximum interest allowed by law for this type
of obligation shall accrue.

                                    AGREEMENT

In Santiago, Chile, on October 4, 1999, between COMPANIA DE TELECOMUNICACIONES
DE CHILE S.A. ("CTC"), a Chilean corporation operating in the telecommunications
industry, represented by its General Manager Mr. Claudio Munoz Zuniga, both

and TERRA NETWORKS S.A. ("TN"), a Spanish corporation operating in the
telecommunications industry, with domicile at Edificio Atica No. 1, Via de las
Dos Castillas 33, Pozuelo de Alarcon 28224, Madrid, Spain, represented, as shall
be set forth, by Mr. Juan Perea Saenz de Buruaga, of the same domicile as above,
who state the following:

ONE: Pursuant to a private document of this date signed by CTC Mundo and
Telefonica Interactiva Chile Ltda. (hereinafter to be referred to as "TI
Chile"), the former sold the latter its entire ownership interest, which to date
totaled 95% of the outstanding shares (while promising to sell the remaining 5%)

access services and other complementary and related services. CTC Mundo will
also have an option to invest the proceeds from the sale of its CTC Internet
shares in shares of TN.

TWO: As a consequence of TN's interest in incorporating into its property CTC
Internet S.A. in order to expand its strategy of developing the Internet

such strategy in its capacity as shareholder of TN, each party assumes the
following commitments:
<PAGE>   2

ONE. CTC.

CTC and CTC Mundo will provide CTC Internet with all telecommunications
services, as well as those complementary and related services (such as billing
and collection services, commercial distribution and other similar services)
that they are currently providing or that they will provide in the future,
subject to market terms and in any case under conditions at least equal to the
most favorable terms at which they are providing them to third parties at such
time as those services are requested by CTC Internet. This obligation of CTC and
of CTC Mundo will also be extended to the services they provide through their
subsidiaries. Finally, any corporations affiliated with CTC and CTC Mundo shall
act diligently and in good faith in ensuring that such companies provide the
services required by CTC Internet under the same terms as they would be required
to do so themselves had they been the direct service providers.

CTC Mundo and CTC promise to give preference to the services of CTC Internet in
carrying out their business activities relating to Internet products and
services to residential customers. The commitment by CTC and CTC Mundo to give
preference to CTC Internet in providing the aforementioned services will be
subject to such services' being provided by CTC Internet under the same market
terms and in any case, under conditions at least equal to the most favorable
terms at which it is providing them to third parties at the time they are
requested by CTC, CTC Mundo, or the corporations controlled thereby.

TWO. TN.

TN promises to ensure that its Chilean subsidiary, CTC Internet, gives
preference to the telecommunications services provided by CTC, CTC Mundo, and
their respective subsidiaries, to the extent that they are provided to CTC
Internet under the terms mentioned in number One above.


                                       2
<PAGE>   3

THREE: Duration. This Agreement shall apply for a period of ten (10) years
counting from this date, provided that TN remains as direct or indirect majority
shareholder of CTC Internet.

FOUR: Breach of contract. Failure to fulfill the obligations provided for in
this Agreement shall not entitle any party to request its cancellation, but
rather only the right to require enforcement of compliance and the respective
indemnification of losses.

FIVE: Arbitration. In the event of any dispute relating to the validity,

<PAGE>   14

      4.17.3      The Income Tax Returns accurately and completely reflect the
                  facts regarding the revenues, properties, operations, and
                  status of any entity that must appear thereon;

      4.17.4      The charges, accumulations, and reserves for Taxes owed or
                  accrued but not yet payable with respect to INFOSEL's
                  revenues, properties, or operations as indicated in INFOSEL's

                  extensions and waivers have been asserted;

      4.17.8      All Taxes pertaining to INFOSEL have been covered or paid, and
                  no situation has arisen as a result of the audits for which
                  the application of similar principles would lead one to
                  consider the possibility of any tax claim for any year that
                  has not been audited.

                  threatened. Moreover, the Sellers have no knowledge of any
                  facts that might give rise to such actions, lawsuits, or
                  claims.

                  Sellers, and the completion of the transactions provided for

[Initials and signatures illegible]


                                       14
<PAGE>   15

                  otherwise) under such plans, funds, or schemes, vis-a-vis the
                  employees or former employees of INFOSEL;

                  obligations to its employees and the authorities, as well as

                  improper employment practices. There are no actions, lawsuits,
                  or legal, administrative, arbitration, or other proceedings in
                  progress; nor, to the best of the Sellers' knowledge and
                  belief, have any been threatened. To the best of the Sellers'
                  knowledge and belief, no investigations are ongoing or have
                  been threatened against INFOSEL concerning the foregoing, nor
                  do any grounds exist for any action, lawsuit, or legal,

                  INFOSEL;

      4.18.7      Currently, no grievance or arbitration proceedings derived
                  from or in accordance with any collective bargaining
                  agreements exist against INFOSEL, nor are there any grounds
                  for any such claims.;

      4.18.8      INFOSEL has not experienced any organized work stoppages in
                  the past three years.

                  been canceled, abandoned, or terminated in any other manner;

[Initials and signatures illegible]


                                       15

      4.19.3      INFOSEL is not in breach of any license, concession,
                  authorization, or agreement whereby INFOSEL has been granted a
                  gratuitous or onerous use of any trademarks, business slogans,
                  software, copyrights, confidential information, or any other
                  type of intellectual property, and there is no current or
                  imminent proceeding against INFOSEL because of any breach or
                  irregular compliance therewith.

      4.19.4      INFOSEL has complied with the duties of secrecy and
                  confidentiality imposed by the various licensing, concession,
                  authorization, and other agreements it has executed. These
                  agreements are in force, and there is no current or imminent
                  claim because of the divulgement of any trade secrets that are
                  the property of any third parties or that INFOSEL or its
                  employees, partners, executives, or officers have used
                  improperly;

      4.19.5      The licenses and agreements mentioned in Exhibit 7 are binding
                  subject to the terms thereof. None of the processes that are
                  currently used by INFOSEL, nor any of the properties,
                  products, or services contracted for, sold, or provided by
                  INFOSEL, nor any of the trademarks, business slogans, labels,
                  or other marks or copyrights used by INFOSEL, nor any of the
                  other items mentioned in Exhibit 7 violate the rights of any
                  other person or entity. Moreover, INFOSEL has not received
                  notice of any such violation, and the Purchaser may continue

assume control of the defense, settlement, or resolution of such Indemnified
Claims, including, at the Purchaser's cost and expense, contracting for
reasonably satisfactory legal counsel for the Sellers; with the understanding,

by the Purchaser, and in the latter case, at its sole cost and expense) in any
of said cases, and in this event, the legal counsel appointed by the Purchaser
shall be obligated to cooperate with the Seller's legal counsel in that defense,
settlement, or resolution.

                  arbitrators do not agree on the designation of the third
                  arbitrator, then either of the arbitrators may petition the

             violation thereof, shall be submitted to arbitration pursuant to
             the regulations of the International Chamber of Commerce of Paris,
             to the extent that said regulations are not incompatible with this

             question arises, and in no case shall it be made after the date on

             such claim, dispute, or any other question, has been barred under
             the applicable statute of limitations.

      14.4.1 The panel shall be comprised of three arbitrators. Each of the
             Parties to this Contract shall name one of said arbitrators, and
             the two arbitrators so named shall designate a third: with the
             understanding, however, that if the two arbitrators fail to reach
             agreement regarding the naming of the third arbitrator, either of
             the arbitrators may request that the International Chamber of
             Commerce of Paris make the designation;

      14.4.1 The arbitration shall be conducted in Dallas, Texas, in Spanish
             and/or English.

      14.4.1 For the present, each Party waives the requirement for
             hand-delivered notification of arbitration, and agrees that
             notification may be made in writing, by registered mail, with
             acknowledgement of receipt, to the address provided in this
             Contract, and any request made in this manner shall be considered
             effected on the tenth Business Day after such request has been
             mailed.

      14.4.1 Any judicial proceeding brought as support for the arbitration with
             respect to this Contract, including precautionary measures, shall
             be submitted to the competent judicial authority. Each Party to
             this document (a) accepts, generally and unconditionally, the
             exclusive competence of said court and any related appeals court,
             and irrevocably waives any objection it may have, now or in the
             future, with respect to the forum of any lawsuit, legal action, or
             proceeding

      sum of US$220,000,000.00 (Two hundred twenty million dollars 00/100) in
      currency of legal tender of the United States of America by the
      Institutional Price per Share, using the Dollar/Euro Exchange Rate on the

2.2   Preemptive Right. At any time as of the Closing Date on which Bidasoa
      acquires TN Shares, Telefonica, S.A. shall have a preemptive right for

      exercised through Telefonica, S.A. or by any third party that is
      designated, with respect to all TN Shares that Bidasoa offers for sale.
      Before transferring any TN Share, Bidasoa must notify Telefonica, S.A. of
      its desire to transfer them, including the terms and conditions to which
      such transfer would be subject. In such event, Telefonica, S.A., shall
      have five (5) Business Days in which to notify Bidasoa as to whether or
      not it wishes to exercise its preemptive right. After that time period,
      with no response from Telefonica, S.A. or if Telefonica, S.A. declines to
      exercise its right, Bidasoa shall be at liberty to transfer its TN Shares
      for thirty (30) Business Days after any of these eventualities occurs,
      under terms and conditions no less favorable for Bidasoa than those
      established in the original offering. Should it exercise its preemptive
      right to acquire such TN Shares, Telefonica, S.A. shall have the same
      period of thirty (30) Business Days in which to formalize the acquisition,
      pursuant to the terms and conditions established in the Bidasoa offering.

      Subsidiary, Direct Subsidiary or Controller must expressly and with
      advance notice to Telefonica, S.A., assume each and every one of the
      obligations that correspond to Bidasoa under this Contract and the rights
      of Telefonica, S.A. derived from this Contract shall not be adversely
      affected by virtue of such transfer.

2.4.  Exercise of Voting Right. Bidasoa agrees to exercise the voting right that
      it has as a holder of the TN Shares that it acquires under this Contract
      pursuant to the instructions that it receives from Telefonica, S.A., on
      the understanding that in resolutions that in a discriminate fashion
      adversely affect only the interests of Bidasoa as a holder of the TN
      Shares, Bidasoa shall not be required to vote pursuant to the instructions
      that it receives from Telefonica, S.A.

2.5.  TN Stock Administration Deposit Contract. To guaranty performance of the
      various obligations that Bidasoa assumes under this Contract, Bidasoa
      agrees to deliver any TN Shares that it comes to acquire under this

their will in the following terms:

CLAUSE ONE. ESTABLISHMENT OF DEPOSIT

1.1      Pursuant to Clause 2.4.5 of the Agreement for the Sale of Class A
         Shares of TN-Mexico, Bidasoa hereby delivers, in deposit to the
         Trustee's administration, the TN-Espana Shares that it receives on
         today's date from TN-Espana in payment of the Remaining Price or the
         New Remaining Price, as applicable (hereinafter the "Deposited
         Shares"), so that the Trustee may administer them in accordance with
         the instructions and purposes set forth herein. The signing of this
         Agreement formally constitutes a receipt granted by the Trustee in
         favor of Bidasoa for the Deposited Shares.

1.2      Bidasoa expressly states that all fruits of any nature generated in
         favor of Bidasoa as registered stockholder of the Deposited Shares,
         including any dividends or bonus stock issued, also form a part of the
         deposit.

1.3      The Parties agree that the Deposited Shares shall remain on deposit to
         secure compliance with (i) any obligations arising from the Agreement
         for the Sale of Class A Shares of TN-Mexico that are the responsibility
         of Bidasoa and that subsist subsequent to the Closing under the terms
         thereof, and (ii) the restrictions set forth in Clause 2.4 of the
         Agreement for the Sale of Class A Shares of TN-Mexico with respect to
         the holding of the Deposited Shares, including but not limited to:




                                       6                              [initials]
<PAGE>   21
         1.3.1    Restrictions on the sale of the Deposited Shares set forth in
                  Clause 2.4.1 of the Agreement for the Sale of Class A Shares
                  of TN-Mexico;

         1.3.2    Preemptive rights granted on the Deposited Shares under Clause
                  2.4.2 of the Agreement for the Sale of Class A Shares of
                  TN-Mexico; and

         1.3.3    The obligation to exercise voting rights derived from the
                  Deposited Shares so long as Bidasoa is their owner, in
                  accordance with the instructions received from Telefonica,
                  S.A. in accordance with the terms of Clause 2.4.4 of the
                  Agreement for the Sale of Class A Shares of TN-Mexico.

CLAUSE TWO. RELEASE OF DEPOSITED SHARES

The parties agree that the Deposited Shares shall be automatically released from
the deposit established hereunder upon compliance with the terms for lifting the
restrictions on the sale of the Deposited Shares referred to in Clause 1.3.1
hereof, and only in the proportion in which said restrictions are lifted, unless
prior to said date the Arbitrators, as interim equitable relief, have notified
the Trustee that TN-Espana has a well-founded claim with respect to Bidasoa's
performance of its obligations under the Agreement for the Sale of Class A
Shares of TN-Mexico. The trustee shall only release and deliver the Deposited
Shares to Bidasoa to the extent that (i) the Arbitrators notify the Trustee that
TN-Espana's claim is well-founded, without need for said claim at that time to
be fully proven by TN-Espana and (ii) that said claim is for an amount exceeding
the value at that time of the shares that shall remain subsequent to the
corresponding release.

In the event that there are shares whose release is pending and a claim of the
type mentioned herein is received from the Arbitrators, the Trustee may only
retain the portion of the shares pending release whose value corresponds to the
amount claimed.

Even if the Arbitrators have provided notice of a claim, the Trustee, at
Bidasoa's request, shall authorize the sale of shares on which restrictions have
been lifted, but that have been retained by the Trustee in the cases mentioned
herein, provided that the Trustee is ensured that the net proceeds of the sale,
after applicable taxes, shall form part of the Deposit for the effects set forth
herein.




                                       7                              [initials]
<PAGE>   22
In the event that as a result of one or more TN-Espana claims filed with the
Trustee by the Arbitrators, the Trustee retains shares after the sales
restrictions have been lifted that are referred to in Clause 2.4.1 of the
Agreement for the Sale of Class A Shares of TN-Mexico, and a final determination
is later made that said claim is not well-founded, TN-Espana shall be obligated
to indemnify Bidasoa through the payment of interest at the LIBOR Rate plus six
(6) percentage points. Said rate shall be applied to the value of the retained
shares or retained amount, as applicable, plus any expenses and/or costs
incurred by Bidasoa in relation to said unfounded retention. The interest
mentioned herein shall be calculated as of the date on which the Trustee placed
the hold on the shares or cash, and up until the same have been delivered to
Bidasoa.

CLAUSE THREE. ENFORCEMENT OF DEPOSIT IN THE EVENT OF A BREACH

The Deposited Shares shall form a part of Bidasoa's net worth, despite being
subject to the deposit established hereunder. Thus, the Deposited Shares shall
at all times be subject to satisfying any obligations that Bidasoa has failed to
perform pursuant to this Agreement or pursuant to the Agreement for the Sale of
Class A Shares of TN-Mexico or applicable law. The Trustee shall abide by all
final orders pronounced by the Arbitrators or by any court that has competent
jurisdiction with respect to the Deposited Shares. The release of the Deposited
Shares shall not limit any right that TN-Espana may have over the same pursuant
to applicable law.

CLAUSE FOUR. TRUSTEE'S AUTHORITY AND OBLIGATIONS

For purposes of performing the role assumed by the Trustee hereunder, the
Trustee is empowered to exercise the following authority:

4.1      Receive the Deposited Shares on deposit, keep them, and deliver them to
         whom they correspond pursuant hereto and pursuant to the Agreement for
         the Sale of Class A Shares of TN-Mexico, provided that the terms of
         Clause Two hereof are met.

4.2      So long as this agreement remains in effect, Bidasoa expressly grants
         the Trustee the right to exercise all corporate rights corresponding to
         it as the registered stockholder of the Deposited Shares.

4.3      The Trustee shall cast its vote on the deposited shares in the same way
         as the votes are cast on the shares of TN-Espana that belong to
         Telefonica, S.A. For said purpose, it shall make a prior request to
         Telefonica, S.A. for written instructions as indicated in Clause 6.3
         hereof. If for any reason the Trustee should fail to receive voting
         instructions, it must necessarily cast its vote in the same way as
         Telefonica, S.A. does, so as to comply with the terms of Clause 2.4.4
         of the Agreement for the Sale of Class A Shares of TN-Mexico. It is
         nonetheless understood that on resolutions that particularly and
         adversely affect the interests of Bidasoa alone as the stockholder of
         the TN Shares [sic], the Trustee shall not be obligated to vote in
         accordance with the instructions it receives from Telefonica, S.A.




                                       8                              [initials]
<PAGE>   23
4.4      So long as this Agreement remains in effect, Bidasoa recognizes that
         the deposit includes all economic rights to which it is entitled as the
         registered stockholder of the Deposited Shares, especially the right to
         dividends. All economic risks generated for Bidasoa on the Deposited
         Shares as a TN-Espana stockholder shall be turned over to the party
         entitled thereto once the terms of Clause Two hereof have been met.

4.5      The deposit established hereunder shall be extended to and shall
         include any certificates of title, securities, tangible or intangible
         assets, or funds substituting or corresponding to the deposited shares
         in the event of a merger, dissolution, increase or decrease in capital,
         share conversion or share swap, transformation, spin-off, or anything
         else of a similar nature affecting TN-Espana. For said effects, the
         parties agree to grant, when applicable, any and all publicly recorded
         and/or non-recorded instruments as may be necessary or beneficial to
         formalize the increase in the assets that are the subject of the
         previously established deposit.

4.6      Furthermore, the Trustee shall deliver the deposited shares to Bidasoa
         as the sales restrictions are lifted that are referred to in Clause
         2.4.1 of the Agreement for the Sale of Class A Shares of TN-Mexico.

the legal owners of 100% (one hundred percent) of the Common and Preferred

options, rights of refusal or priority for the purchase, and other claims of any
nature, and they have full right, power and authority under their respective
corporate charters, as the case may be, to participate in and vote in the Nutec
extraordinary general shareholders assembly. The number of Common Shares and
Preferred Shares which each Current Controlling Party owns on the date of this

Controlling Parties are liable, Telefonica Interactiva Brasil and/or Nutec
and/or its Subsidiaries shall remain as the sole and exclusive parties liable
for such debtor obligations, including with respect to professional legal fees,
costs and procedural expenses. However, in the event that Telefonica Interactiva

the case, Telefonica Interactiva Brasil must assume 20% (twenty percent) of
the judgment, to the extent that it resulted from the delay.

forth in Clauses 5.5.1 and 5.5.2 above, the Current Controlling Parties fail,
for any reason, to assume the defense of any obligation, debt, claim and/or
process for which they are responsible pursuant to the terms of this Clause 5,
Telefonica Interactiva Brasil and/or Nutec and/or the Subsidiaries shall defend
the case diligently, with the Current Controlling Parties being required to
reimburse all costs incurred by Nutec and/or by the Subsidiaries and/or by
Telefonica Interactiva Brasil in the respective defense, plus a compensatory
fine of 20% (twenty percent) of the total expense, even in the event that the
defense is successful, and the Current Controlling Parties must, after the
defense, assume direction and control of the cases.

5.7. The Current Controlling Parties shall keep Telefonica Interactiva Brasil
and Nutec or the Subsidiaries, as the case may be, periodically and fully
informed as to progress and all occurrences, facts, measures or steps that are
relevant to the proceedings and claims over which direction and control are its
responsibility pursuant to this Agreement.

5.8. It is henceforth agreed that Telefonica Interactiva Brasil, Nutec and the
Subsidiaries, as the case may be, shall cooperate (including in the delivery of
the documents needed for undertaking the corresponding proceeding) provided that
they have been requested along with the Current Controlling Parties and the
attorneys selected thereby for undertaking the proceedings for which the former
are liable, and control pursuant to the terms of this Clause 5, at all times
avoiding engaging in acts which may hamper the responsibility of the Current
Controlling Parties. In the same way, the Current Controlling Parties promise to
not engage in any act nor to permit the practice of any act or the occurrence of
any event, with respect to the proceedings which may result in an adverse
effect, or may harm the interests of Telefonica Interactiva Brasil, Nutec and
the Subsidiaries or constitute a negative precedent, contrary to the interests
thereof. The Parties agree to make their best efforts to cooperate with each
other in order to close out all proceedings in a fashion both definitive and
satisfactory to the Parties, at all times in compliance with the right of the
Current Controlling Parties to exhaust all procedural and administrative levels
and to resort to the parceling of debts, the only exception being that
Telefonica Interactiva Brasil shall be entitled to require that the Current
Controlling Parties close the cases in question with a significant likelihood of
loss, based on an opinion from the law offices of Pinheiro Neto Advogados or a
law office of a similar reputation, and which basically are or will be causing
it harm.

vote, at the NUTEC Extraordinary General Assembly to be held on a date to be

      3.1   General Conditions

            The Shares owned by the Parties representing the Corporation's
capital stock, bound to this Agreement pursuant to the terms of Clause 1 above,
the right to subscribe the aforementioned Shares, and the securities supporting
such right or which are convertible into Shares (equivalent to the Shares
themselves for purposes of this Agreement) may not be sold, assigned,
transferred, pledged, given in usufruct or trust, conferred to the capital of
another corporation or in any other way alienated or encumbered, except as
provided for in this Agreement.
<PAGE>   4

      3.2   Minority Shareholder Sale Option

            At any time after the Validity Date, Sylvia and MLSP (hereinafter to
be referred to simply as the "Minority Shareholders") may exercise the option to
sell their Shares to TIB, which in turn hereby promises to acquire the
aforementioned shares ("Sale Option"). The Sale Option may be validly exercised
by the Minority Shareholders singly or jointly.

            3.2.1 Acquisition Price

                  For purposes of this clause, the reference price shall be
considered as being the total value paid by TIB for subscribing its Shares in
the Corporation, pursuant to the terms provided for in the Subscription
Agreement of this date signed with RBS Administracao e Cobrancas Ltda. et al,
i.e., the value in the current legal tender currency of Brazil equivalent to US$
200 million (two hundred million U.S. dollars), in exchange for 100% (one
hundred percent) of the shares issued by the Corporation on this date
(hereinafter to be referred to simply as "Base Value").

            (a) In the event that the Minority Shareholders exercise the Sale
Option within the period between the Validity Date and July 30, 2001
(inclusive), pursuant to the condition set forth in Clause 3.2.2 below, TIB
shall pay the equivalent of 30% (thirty percent) of the Base Value, for the
entire number of Shares it shall acquire from the Minority Shareholders. In the
event that the Minority Shareholders exercise the Sale Option at any time after
July 30, 2001, pursuant to the condition set forth in Clause 3.2.2 below, TIB
shall pay the equivalent of 100% (one hundred percent) of the Base Value, in
addition to the change in the six-month LIBOR ("London Interbank Offered Rate")
for the period, for all the Shares that it shall acquire from the Minority
Shareholders.

            (b) In the event of an increase in the value of the shares after
July 30, 2001 and in the event that the Minority Shareholders exercise the Sale
Option, TIB shall be required to conform to the value resulting from the
increase, assuming at all times that the Minority Shareholders jointly hold
rights to 4% of the total value of the Corporation's capital stock, in the form
described below.

            (c) For purposes of verifying the increased value of the Shares, the
parties may, in the event that they are unable to come to a consensus with
respect to the price, choose among three investment banks and among three
independent auditing firms, one from each sector, which may undertake a
definitive appraisal of the Shares and in particular of the
<PAGE>   5

rights representing 4% of the value of the Corporation's capital stock.

            3.2.2 Guarantee of Non-Dilution

            (a) In the event of any acquisition of the Minority Shareholders'
Shares by TIB, the acquisition price to be paid by TIB shall assume, under all
circumstances, 4% (four percent) of the value of the Corporation's total capital
stock as being the actual corporate interest of the Corporation's Minority
Shareholders, even if, on the occasion of such acquisition, such percentage does
not hold by virtue of the dilution of the Minority Shareholders' corporate
interests as a consequence of the Corporation's capital increases after that
date, which were subscribed by TIB only, in view of the Minority Shareholders'
waiver of their right of first refusal to subscribe. Of the total 4% (four
percent) referring to the value of the capital stock, 1% (one percent) shall be
paid to Silvia, and the remaining 3% (three percent) to MLSP.

      This commitment shall henceforth be binding on TIB, and shall remain
binding in the event of any assignment or transfer of any portion of the Shares
from TIB to a third party which does not assume it on the occasion of the
aforementioned assignment and transfer, such that it be henceforth set forth
that such commitment shall retain in full effect the right of the Minority
Shareholders to securities representing 4% of the value of the Corporation's
capital stock, in the form already described above, which right is
unconditionally and irrevocably guaranteed by TIB to the Minority Shareholders,
thereby reflecting the Parties' global understanding and the spirit of the
transaction.

            (b) The Parties recognize that in the near future, in accordance
with the strategic plans of the controlling shareholder's control group, (x) the
Corporation may be subjected to the process of opening its capital to the public
distribution of shares in a country to be defined, which process shall be known
as "IPO (Initial Public Offering)", or (y) also, by contrast with the
Corporation, any entity which indirectly controls it, and which operates within
an economic group, may be subject to such process. In either of these events,
the above terms and conditions in this Clause 3.2.2 shall apply, i.e., it shall
be assumed that the Minority Shareholders hold total rights equivalent to 4% of
the shares representing the entire capital stock of the Corporation, with the
consequences resulting from this definition of the volume of shares placed into
an "IPO" and that, in the event mentioned in item (y) of this paragraph, any
positive increase in the value of the Corporation's shares which may have
indirectly occurred through its control having passed through the process of an
IPO shall be taken into consideration. The parties acknowledge that in the case
of
<PAGE>   6

an offering of capital through the "IPO" process, the Minority Shareholders
shall at all times be entitled to the real values attributed to and obtained
through this transaction, at all times equivalent to 4% of the shares
representing the Corporation's total capital stock.

      3.3   Right of First Refusal

            (a) No Party may sell or in any form transfer or guarantee to third
parties or to any other Party to this Agreement any or all of its Shares without
first offering them, in the capacity of "Offering Party," to all other Parties,
who shall have right of first refusal to acquire them in proportion to the
number of Shares which they hold on the date this offering was made, under
identical conditions as those of the interested third party (shareholder or
not), and the exercise of the right of first refusal mentioned herein must occur
within a maximum of 30 (thirty) days after the date of issuance of the
notification from the Offering Party. (b) With respect to the subscription of
new Shares, in the event of a waiver by any of the Shareholders, such others as
wish may completely exercise their right of first refusal on the portion covered
by the waiver.

      3.4   Permitted Transfers

            The restrictions of this Clause shall not apply to transfers of
Shares to corporations controlled by the Parties, for the case of Minority
Shareholders, and to subsidiary corporations, parent companies or those under
the same control, for the case of TIB, provided that such subsidiary
corporations of the Parties become, in turn, integral parties to this Agreement.

4.    NON-COMPETE

      4.1 The Minority Shareholders, on their own behalf and on that of their
subsidiary corporations, controlled companies or affiliates, direct or indirect,
as well as their partners, directors, employees and representatives, promise
irrevocably and unconditionally to not compete with the Corporation so long as
they are shareholders of the Corporation and for a period of 12 months after
their withdrawal from the Corporation, solely with respect to the activities
currently engaged in by the Corporation.

on that of their subsidiary corporations, controlled companies or affiliates,

promise, directly and indirectly, by means of any other individual or legal

Business. For the purposes provided for herein, "Employee" shall mean and
include parties employed by the Corporation and its Subsidiaries on this date or
during the time of the execution of any actions prohibited by this item (a), in
any position or function, even in management. The obligation assumed herein
shall remain in force for a period of 18 months as of this date with respect to
Employees, except with respect to the Employees mentioned in Annex 1, with
respect to which the obligation shall remain in force for 18 months after this
date.

      (b) insofar as they are shareholders of the Corporation and for a period
of 18 months after their withdrawal from the Corporation, [not?] to request,
attract, persuade or induce any Client or Supplier, in accordance with the
definitions provided herein, to cancel, reduce or fail to renew or expand its
agreements or other relationships with the Corporation or any of its
Subsidiaries, to become a client thereof or to formalize any agreement or any
other relationship of this type with a competing business. For the purposes set
forth herein, "Client" shall mean and shall include all clients of the
Corporation and/or its Subsidiaries during a period of 18 months immediately
prior to the date this Agreement is entered into or those which may be clients
of the Corporation and/or of its Subsidiaries, at any time; "Supplier" shall
mean and shall include all entities from which the Corporation and/or its
Subsidiaries acquire goods and other materials during the 18-month period
immediately prior to the date this Agreement is entered into or from which the
Corporation and/or its Subsidiaries purchased goods and other materials at any
time.

      4.3 The Non-Controlling Shareholders promise also, on their own behalf and
on that of their subsidiary corporations, parent companies, controlled companies
or affiliates, to ensure that their partners, directors, employees and
representatives act in the same form, to persuade any Employees seeking to be
placed in a job or independent service to remain in the Corporation or in the
subsidiaries for a minimum period of 6 months prior to the intended engagement.
<PAGE>   8

      4.4 With respect to the joint development of future processes and
preferential treatment in hiring, the Parties agree to the following: in the
event that the Minority Shareholders are invited to participate as investors in
projects for the development of content sites or other sites of a commercial
nature, the Minority Shareholders hereby promise to offer the opportunity to the
majority shareholder such that the latter, if it so wishes and at its sole
discretion, may also have access to participation in the project, under
conditions to be established at the time by the interested parties.

5.    DIVISION OF PROVISIONS

      In the event that any provision of this Agreement is or becomes invalid or
unenforceable, the other provisions thereof shall remain in full force and
effect, and in such case, the Parties shall enter into good faith negotiations,
with a view to replacing the invalid or unenforceable provision by another
which, insofar as is possible and in reasonable fashion, fulfills the same
objective and has the desired effect.

6.    COMMUNICATIONS

      Any notice or communication deriving from this Agreement shall be in
writing, and may be made solely by fax, sent to the address of the recipient as
stated in the preamble of this Agreement or to another address which may be
communicated thereby to the other Parties of this Agreement, which must receive
an immediate written notice of its receipt.

7.    SPECIFIC EXECUTION

      A breach or failure by the Parties to comply with any of the terms and
conditions stipulated herein shall entitle the other harmed Party to demand in
court fulfillment of the specific obligation, pursuant to Article 118 of Law No.

8.    GENERAL PROVISIONS

      8.1 No change to this Agreement shall be valid unless made in writing and

equivalent to 4% of the Corporation's worth;

WHEREAS, furthermore, any entity directly or indirectly controlling the
Corporation may implement, by November 1999, a process of public offering of
capital pursuant to an "Initial Public Offering" ("IPO"); and

      3.2.3. IPO-related Obligations:

      (a) The Parties acknowledge that, by November 30, 1999, according to the
      strategic plans of the controlling group of the controlling shareholder,
      any entity indirectly controlling it and relevant within the same business
      group may implement a process of public offering of capital and public
      distribution of its shares in a country yet to be defined, a process known
      as IPO (the corporation in question hereinafter referred to as "IPO
      Corporation").

      (b) Upon such public offering of capital and public distribution of the
      IPO Corporation's shares, TIB's controlling shareholder undertakes to
      remit to Brazil such funds as shall be capitalized in a company with
      specific purpose ("SPE"), which shall be obligated to acquire for the

      institutional price thereof converted from the


                                                                               3

      Euro into U.S. dollars at the average rate of the day prior to that of the
      IPO, either old shares or new shares originating from the IPO process such
      as issued by the IPO Corporation. MLSP and Silvia, in turn, agree to
      purchase immediately all said shares which the SPE shall hold in the IPO
      Corporation by virtue of the aforesaid acquisition, paying for them with
      the total amount of their shares held in the Corporation.

      (c) If the IPO process is not implemented by the IPO Corporation by
      November 30, 1999, the terms previously agreed upon pursuant to Section
      3.2.2 (b) of the Shareholders' Agreement shall remain valid among the
      Parties, and this Addendum to the Agreement shall be disregarded.

      (d) MLSP and Silvia acknowledge that once the stock exchange process under
      Section 3.2.3 (b) above is implemented, the rights and obligations under
      Sections 3.1, 3.3, 3.4, and 4 (including the clauses thereunder) of the
      Shareholders' Agreement shall remain fully in effect.

      (e) In any circumstances, MLSP managing partners, Sergio and Marcello, and
      Silvia agree, if so required by the IPO Corporation, to remain as
      administrative officers of the Corporation for a term of at least 24
      months from the execution of the Shareholders' Agreement hereunder on June
      15, 1999.

      (f) After six (6) months from the placement date of the IPO Corporation's
      shares and for up to twenty-four (24) months from the execution date of
      the Shareholders' Agreement hereunder, MLSP and Silvia have the right to
      sell to TIB, which in turn is obligated to purchase, for the average price
      quoted on the stock exchange over the six (6) months prior to date on
      which the sale option is exercised by MLSP and Silvia.

      (g) Once such twenty four (24)-month term shall have elapsed from the
      execution of the Shareholders' Agreement, MLSP and Silvia may not sell or
      otherwise transfer or pledge to third parties, whether wholly or in part,
      their shares held in the IPO Corporation without first offering them, as
      "Offering Party," to TIB, which shall have a first-refusal right to the
      acquisition of such shares at the average price of the IPO Corporation's
      shares as quoted on the day prior to the exercise of the sale option by
      MLSP and/or Silvia, such first-refusal right as referred to hereunder to
      be exercised no later than within twenty four (24) hours from the time of
      delivery of a written communication notice to the Offering Party.


                                                                               4

Agreement in four (4) counterparts of identical contents and for a sole effect,
duly executed in the presence of the two (2) undersigned witnesses.

between Grupo TEKNOLAND and Grupo TELEFONICA in general and TELEFONICA
INTERACTIVA, S.A. in particular.

TELEFONICA INTERACTIVA, S.A. shall make available to Grupo TEKNOLAND the
aforementioned potential for the purpose of maximizing, as far as possible, the
company's development. Also, Grupo TELEFONICA agrees to provide the resources
necessary for GRUPO TEKNOLAND's development by effecting the capital increases
agreed to by the shareholders, which transactions will result in the concomitant
reduction of the current shareholders' interest without the capital increase.

EIGHTH. - ADVANCE PAYMENT FOR PURCHASE OF FUTURE SHARES WITHIN THE FRAMEWORK OF
THE AGREEMENTS REACHED.

Without prejudice to the time period provided for in the SECOND agreement for
the accomplishment of all the transactions agreed upon, TELEFONICA INTERACTIVA,
S.A. provides, at this proceeding, to the shareholder of CORPORACION REAL TIME
TEAM, S.L., the sum of 250,000,000 (TWO HUNDRED FIFTY MILLION) pesetas as
payment on account for the agreed-upon purchase of shares of CORPORACION REAL
TIME TEAM, S.L.

If, for reasons imputable to CIERV or its shareholders, the acquisition of
interest provided for in the FIRST stipulation of this contract does not take
place, this contract shall be rescinded as a matter of law, and CIERV shall
return the advance payment.

NINTH. - COMMITMENT OF CIERV SHAREHOLDERS

The current shareholders of CIERV, managers of GRUPO TEKNOLAND, agree to remain
in the management of Grupo TEKNOLAND as long as they are majority shareholders
of Grupo.

Likewise, from the time they cease to possess the majority of Grupo capital
stock, as a result of the exercise of any of the options included in this
contract, they agree to cooperate in the search for a new management team
acceptable to TELEFONICA INTERACTIVA, S.A., and to remain in the management
until said team is accepted, with a maximum of eighteen months. This commitment
to permanence in this second paragraph shall be invalid if any of the events
described in section 6.1 of this contract occurs.

Throughout the time that CIERV or its current shareholders own shares in Grupo
TEKNOLAND or during the three years after which they cease to own any interest,
the aforementioned shareholders shall not compete with Grupo TEKNOLAND by
directly or indirectly engaging in activities competing with those carried out
by Grupo TEKNOLAND.

Finally, and as long as TELEFONICA INTERACTIVA, S.A. is a minority shareholder
of CORPORACION REAL TIME TEAM, S.L., the current shareholders of CIERV agree to
not transfer their shares in the latter to third parties unrelated to the
corporation; family members up to the third degree shall not be considered third
parties for these purposes.

And thus they execute it, in the place and on the date shown above.

      The parties expressly agree that, in the event of a failure to observe the
      periods provided for in Agreement 4.2 above for the approval and/or
      adoption of all agreements necessary to amend the bylaws of the companies
      within the TEKNOLAND Group shall be construed as producing a supposition
      in addition to those described in Agreement 6.1 below for the exercising
      of the Purchase Option granted TELEFONICA INTERACTIVA, S.A., with the
      Vendors hereby granting the Buyer a Purchase Option (under the same terms
      and conditions as those described in Agreement 6 below) of shares
      representing 26% of Corporacion Real Time Team, S.L., notwithstanding
      compensation for damages suffered to which TELEFONICA INTERACTIVA may be
      entitled as a result of said failure.

4.4   The Sellers hereby inform TELEFONICA INTERACTIVA, S.A., who indicates its

5. Purchase Terms and Conditions. Statements and Assurances.

5.1   The "Purchase Terms and Conditions" referring to the TEKNOLAND Group,
      which have been attached hereto as Attachment 5.1(a), form an integral
      part hereof. The parties state that the price to be made in accordance
      with this Purchase Agreement is based on said Purchase Terms and
      Conditions being true, accurate, and complete.

5.2   The Sellers shall be liable for not fulfilling their obligation to
      transfer and retain fee simple and perfect title and possession of the
      shares that they have sold to TELEFONICA INTERACTIVA (warranty of title
      and hidden defects).

5.3   The Sellers shall be liable to TELEFONICA INTERACTIVA for any error or
      omission in the purchase terms and conditions under the terms set forth
      herein.

      In the event of any errors or omissions in connection with the statements
      made in the Purchase Terms and Conditions, TELEFONICA INTERACTIVA shall be
      entitled to compensation from the Sellers


                                                                              16
<PAGE>   17

      for all damage caused to TELEFONICA INTERACTIVA from the loss or reduced
      company value shown for the value of the TEKNOLAND Group, considered by
      TELEFONICA INTERACTIVA to undertake this operation (meaning, the value of
      the TEKNOLAND Group) if all Purchase Terms and Conditions had been true,
      complete, and accurate.

      Moreover, when errors or omission in the Purchase Terms and Conditions
      give rise to damage or expense to TELEFONICA INTERACTIVA that is not a
      result of the reduced company value of the TEKNOLAND Group, the Sellers
      shall directly compensate TELEFONICA INTERACTIVA for the full amount of
      the resulting damage or expense that may have been inflicted on TELEFONICA
      INTERACTIVA.

      In the event that the Sellers exercise their purchase options in
      accordance with the provisions of Agreement 7 herein, its obligation to
      compensate TELEFONICA INTERACTIVA for errors or omissions in the Purchase
      Terms and Conditions shall extend to all of the shares in the TEKNOLAND
      Group which may be owned by TELEFONICA INTERACTIVA and were purchased from
      the Sellers.

      Once the claim by TELEFONICA INTERACTIVA of errors or omissions in the
      Purchase Terms and Conditions has been accepted by the Sellers or, as
      applicable, once the relevance and amount thereof has been assessed by the
      mediator or in the final decision of the arbitrator according to the
      procedure established in the paragraph below, the Sellers shall proceed to
      pay, within a maximum of ten business days from the date on which the
      claim was accepted or upheld, the amount thereof into the checking account
      designated by TELEFONICA INTERACTIVA. In this regard, the parties
      expressly agree upon the possibility of TELEFONICA INTERACTIVA being
      compensated from amounts owed, which may make the payment of said amounts
      to the account of future financial or legal business transactions of any
      type that have been conducted or are to be executed between TELEFONICA
      INTERACTIVA and the Sellers.

      Said amounts shall be paid in increments, applying the legal monetary
      interest rate plus two points until paid in full. To this end, each time
      that an error, omission, debt, liability, or obligation may give rise to a
      reimbursement under the terms hereof, TELEFONICA INTERACTIVA shall notify
      the Sellers of the specific circumstances giving rise to the claim and the
      amounts claimed from the Sellers in damages plus the interest therefor,
      stating the grounds for the claim and the information making it possible
      to properly evaluate the matter. If the Sellers dispute the facts or
      amount, the Sellers shall clearly and concisely notify TELEFONICA
      INTERACTIVA of their position within the 20 days subsequent to the
      notification given by TELEFONICA INTERACTIVA. If there is no reply within
      said 20 days, it shall be presumed that the claim


                                                                              17
<PAGE>   18

      has been accepted. If the Sellers reply to the claim and TELEFONICA
      INTERACTIVA does not agree with the Sellers' position, they shall be so
      notified and any of the Sellers or TELEFONICA INTERACTIVA shall have the
      right to refer the matter for the mediation of the party designated by the
      Dean of the Madrid Bar Association. Said mediator shall establish the
      mediation procedure. The mediator shall act, subject to the second
      paragraph of Article Three of the Law of Private Arbitration No. 33/1998
      dated December 5. If mediation fails, the parties may submit the dispute
      to an arbitrator for a final decision in accordance with Agreement 14
      hereof.

5.4   For the purposes of Clause 5, exclusively, a threshold of 5,000,0000 [sic]
      pesetas shall be applied so that, if TELEFONICA INTERACTIVA becomes
      entitled to compensation from the Sellers pursuant to this clause,
      TELEFONICA INTERACTIVA shall not be reimbursed until the amount(s) claimed
      from the Sellers has exceeded 5,000,000 pesetas. However, once said
      threshold amount has been reached, TELEFONICA INTERACTIVA shall be
      entitled to have the Sellers pay it the full amount of the claims and not
      only for the part exceeding the threshold. To calculate the amounts for
      determining whether or not the minimum threshold mentioned has been
      reached, all claims that may have arisen shall be taken into
      consideration, even though legal rights may have lapsed.

5.5   The period during which the Sellers shall be liable to TELEFONICA
      INTERACTIVA for any errors or omissions in facts, assertions, or
      circumstances set forth in the Purchase Terms and Agreements and the
      attachments thereof shall run from the execution of this Purchase
      Agreement and shall last until (a) the end of the period for exercising
      legal rights, allowing for interruptions, for damages derived from tax and
      social security obligations; (b) three years from said date for any other
      matters. Any claim made by TELEFONICA INTERACTIVA within these Periods (a)
      or (b), as applicable, shall be valid and must be resolved by the person
      or entity competent according to this Purchase Agreement and shall not be
      affected by the arrival of the term established in (a) or (b), as
      applicable.

5.6   In any event, the Sellers shall be answerable for the Buyer's claims in
      proportion to their respective participating interest in the capital of
      CIERV prior to the entry of TELEFONICA INTERACTIVA, up to the limit for
      the total amount received as a price, meaning, a total of [1,101,532,934
      (ONE BILLION, ONE HUNDRED AND ONE MILLION, FIVE HUNDRED AND THIRTY-TWO
      THOUSAND, NINE HUNDRED AND THIRTY-FOUR)] pesetas, unless bad faith on the
      part of TELEFONICA INTERACTIVA is proven.

5.7   As of the execution hereof, until such time as the inscription in the
      Commercial Registry of all agreements pertaining to the partial demerger
      of CIERV and


                                                                              18

      completed, the Sellers agree not to adopt and/or carry out acts, directly
      or through the administrative bodies of the different companies in which
      any agreement or decision contrary to the contents or spirit hereof is
      present or represented and they agree to act at all times according to the
      principle of good faith and business diligence, hereby agreeing to, in any
      event, adopt all those agreements and/or decisions that may be necessary
      to properly carry out the aforementioned business operation.

      Without prejudice to the provisions of the preceding paragraph, the
      Sellers agree, at the moment of adopting decisions within the different
      bodies, to consult with and, as appropriate, request the express approval
      of TELEFONICA INTERACTIVA.

5.8   Sellers' Guarantee for possible contingencies in the Demerger Balance
      Sheet of CIERV, S.L. The Sellers state that the CIERV Demerger Balance
      Sheet dated June 30, 1999 (hereinafter referred to as the "Demerger
      Balance Sheet") reflects the financial, net worth, and economic position
      of the Company as of that date and they guarantee CIERV itself and
      TELEFONICA INTERACTIVA for any debt, contingency, or reduced company value
      that is not included or duly accounted for on the Demerger Balance Sheet.

      CIERV. S.L. shall not entail any tax liability whatsoever for CIERV or for
      TELEFONICA INTERACTIVA.

5.9   Sellers' Guarantee for possible contingencies due to a failure to declare
      the sole proprietorship of REAL TIME TEAM, S.L. on the part of its sole
      shareholder, CIERV. The Sellers indicate and guarantee that they shall
      directly compensate CIERV or the company that may take its place, upon any
      claim, debt, or loss that CIERV may incur as a result of a failure to
      declare the sole proprietorship of REAL TIME TEAM, S.L. during the period
      in which CIERV was the sole shareholder thereof.

5.10  The Sellers shall assume responsibility, while holding TELEFONICA
      INTERACTIVA harmless, for any claim filed by any worker of the TEKNOLAND
      Group as a result of a wage dispute between the wage earned and that

      that occurred prior to the purchase of the shares covered by this

       elimination of TELEFONICA INTERACTIVA, S.A. as a business line of the
       TELEFONICA Group; 3) A change of strategy of TELEFONICA S.A. which
       implies the elimination or significant loss of importance of the business
       related to providing Internet services in the set of activities of the
       TELEFONICA Group with regard to the current situation; 4) Reorganization
       of the TELEFONICA Group, as a result of which TELEFONICA INTERACTIVA,
       S.A. reports to another business unit and not to the Office of the
       Chairman of the Group as it currently does, entailing a change in
       strategy with regard to the business of the TEKNOLAND Group; 5) A change

       integrated, has not been the object of an IPO. It shall not be necessary
       for the 40 month term to have elapsed if TELEFONICA INTERACTIVA, S.A.

       stock or stock


                                                                              23

      The purchase price of the shares, in the event the call option is

      acquired may not be transferred to a third party for a term of 18 months
      from the date of purchase without the express consent of TELEFONICA

It is the full intent of the shareholders that significant synergies shall exist
between the TEKNOLAND Group and the TELEFONICA Group in general, and TELEFONICA
INTERACTIVA, S.A. in particular.

TELEFONICA INTERACTIVA, S.A. shall make this potential available to the
TEKNOLAND Group in order to maximize the development of the Company to the
greatest extent possible. Furthermore, the TELEFONICA Group agrees to contribute
the resources necessary for development of the TEKNOLAND Group by means of
capital increases resolved by the shareholders, transactions which shall result
in the corresponding dilution of the holdings of the current shareholders if
they do not accept the capital increase.

10. Commitments of the Shareholders of CIERV NUEVA

10.1  The Sellers, who are shareholders of CIERV NUEVA and managers of the
      TEKNOLAND Group, agree to continue to manage the TEKNOLAND Group as long
      as they are majority shareholders of the Group.

10.2. Likewise, from the time at which they are no longer majority shareholders
      of the Group, as a result of any of the call options stipulated herein
      being exercised, they agree to cooperate to find a new management team, to
      be approved by TELEFONICA INTERACTIVA, S.A., and to continue to manage
      until said team has been accepted, up to a maximum of eighteen months. The
      obligation contained in this second paragraph shall become invalid if any
      of the events described in paragraph 8.1 herein occur.


                                                                              24
<PAGE>   25

10.3. Throughout the time that CIERV NUEVA or its current shareholders own
      shares of the TEKNOLAND Group, or for three years after such time as they
      no longer own shares, the shareholders shall not compete with the
      TEKNOLAND Group by directly or indirectly engaging in activities which
      compete with the activities pursued by the TEKNOLAND Group.

      For purposes of the previous paragraph, the parties expressly state that
      the price established in Article 2 of this Agreement includes, for all
      purposes, indemnification to the Sellers for their non-compete commitment
      established in the previous paragraph.

10.4. Finally, while TELEFONICA INTERACTIVA, S.A. is a minority shareholder of
      CORPORACION REAL TIME TEAM, S.L., the current shareholders of CIERV agree
      to not transfer their shares in CIERV NUEVA to third parties outside of
      the company; third parties do not include their family members up to the
      third degree of kinship.

10.5. Failure to perform the commitments assumed under this Agreement:
      Independently from the indemnification for damages that TELEFONICA
      INTERACTIVA, S.A. may claim from the Sellers for nonperformance of any of
      the commitments assumed under this Agreement, the parties expressly agree
      that in the circumstances indicated in paragraphs 10.2 and 10.3 above,
      TELEFONICA INTERACTIVA shall be entitled to receive from the Sellers, as a
      penalty, 50% of the amount that the Sellers received from TELEFONICA
      INTERACTIVA as a result of this stock sale, plus, if applicable, any

      as a result of exercising the call options provided in this Sale
      Agreement.

shared equally, provided that there is no provision to the contrary in any of
the articles of this Agreement.

pesetas. With this act, TI delivers, through a transfer of the amount of two
hundred million (200,000,000) pesetas to the account designated by INFOSEARCH,
by way of payment on account with respect to the aforementioned sale. This
amount is deemed to be received with this act.

Legalization of the stock sale will take place within the period set in the
Seventh Agreement of this instrument, once it is reviewed and once the financial
condition and assets of OLE, as shown in the financial statements incorporated
into this agreement as Exhibit 1, are found to be satisfactory.

Two.- Increase of capital stock of OLE

Once the purchase of OLE's stock to which the foregoing agreement refers is
legalized, TI will take two steps to increase OLE's capital in accordance with
the following specifications. TI will take possession of and pay in all shares
created:

a)    Increase in the amount of one billion (1,000,000,000) pesetas through a
      cash contribution.

b)    Increase in the amount of two billion (2,000,000,000) pesetas through a
      non-cash contribution consisting of a contribution of assets related to

      TI The valuation of the assets to be contributed in this capital increase
      is expressly accepted by the parties.

successful conclusion at the time when they may obtain the highest value. They
will make every effort to bring this to fruition before July in the year 2000.

Until that time, TI agrees not to carry out subsequent capital increases in OLE,
of which the purpose would be to dilute the shares purchased, as indicated in

One.      TELEFONICA undertakes to enable INFOSEARCH to acquire shares
          representing the capital stock of T.I. which represent, by means of
          the increase in capital referred to in the following paragraph,
          2.4649% of the new capital stock of T.I. (hereinafter referred to as
          the Shares) at a total price, with the issue premium, if any,
          included, of TWENTY-ONE MILLION FIVE HUNDRED AND FORTY THOUSAND UNITED
          STATES DOLLARS (US $21,540,000), which shall be converted into Spanish
          pesetas according to the official rate of exchange for the dollar on
          the date of the signing of the present contract.

          This acquisition is to be effected by means of the subscription of
          4,928,000 common shares, fully paid-in and with all of the
          organizational and economic rights which may pertain to them, by
          INFOSEARCH in an increase in capital to take place at T.I. within a
          period of time which shall not exceed 45 days from the date of the
          signing of this agreement.

          The amount of the capital increase referred to above shall be
          delivered by means of a check or checks, not transferable by
          endorsement, or a bank transfer or transfers for the total amount
          within a period of five days from the adoption of the resolution to
          increase the capital.
Two.      On its part, INFOSEARCH undertakes to subscribe the shares of T.I.
          referred to in Article One, and at the price indicated.
Three.    The percentage of the shares, of the total capital stock of T.I.,
          acquired by INFOSEARCH in accordance with Article One, is to be
          reduced as a result of the capital increases established below, in
          which INFOSEARCH shall not participate, to an equity holding of 1.76%
          of the total capital stock which T.I. finally has by means of the
          public placement of its shares, then represented by a total of
          280,000,000 shares and thus with 4,928,000 shares pertaining to
          INFOSEARCH.


                                                                               2

<PAGE>   3

          If the number of shares represented by the capital stock of T.I., once
          the public offering is carried out, is different from the envisioned
          280,000,000 shares, the parties shall proceed to carry out the
          corresponding, proportional adjustment by the number of shares owned
          by INFOSEARCH so that the equity holding of INFOSEARCH in the final
          capital of T.I. shall be 1.76% thereof, and this without any cost
          whatsoever to INFOSEARCH.

          The capital increases which T.I. undertakes to carry out, effected in
          relation to implementing a placement of T.I. on the securities
          exchange, are the following:

          -  That pertaining to the options plan in favor of executives of T.I.,
          provided for at 5% of the capital, after the increase.

          -  That pertaining to the public offering.

          INFOSEARCH waives such preemptive right in the mentioned capital
          increases as it may be conferred by virtue of its status as a
          shareholder of T.I.

          In addition, and in order to facilitate the adoption of the company
          resolutions necessary or convenient for proceeding to formulate the
          public offering of shares of T.I. and the mentioned capital increases,
          INFOSEARCH, in its capacity as shareholder of T.I., undertakes to
          attend the General Meetings Of Shareholders which may be held for such
          purposes and to vote in favor of the proposals for resolution
          submitted for consideration provided that it does not contravene that
          established in this contract and does not prejudice its own interests.

          In the event that the businesses of Chile, Peru and Mexico do not
          proceed to be included, T.I. must pay to INFOSEARCH the amount of ONE
          MILLION FIVE HUNDRED AND FORTY THOUSAND UNITED STATES DOLLARS (US
          $1,540,000) pertaining to the advance made by INFOSEARCH for the
          mentioned item.

Four.     Upon carrying out the acquisition described in Article One and the
          placement of T.I. on the financial markets, it shall be deemed that
          the contract dated April 15, 1999 has been fully performed.

          In the event that, upon reaching December 31, 1999, there has been no
          placement of T.I. on the financial markets, both of the parties shall
          have a term of two months, that is, up to March 1, 2000, in order to
          demand that the other party transfer the shares acquired by INFOSEARCH
          at the same price as that paid by the latter.

          In the former eventuality, the contract dated April 15, 1999 shall
          automatically resume full and total effectiveness with no need for any
          additional act by the parties, with INFOSEARCH thereby again acquiring
          the rights in its favor as recognized in the mentioned contract.


                                                                               3

[three sets of script initials]
<PAGE>   4

Five.     INFOSEARCH undertakes, with respect to TELEFONICA, once ownership of
          the Shares is acquired, not to transfer all or part of the said Shares
          to any person or entity without the prior, express consent of
          TELEFONICA; this is until such time as one year has elapsed from the
          placement of the shares of T.I. on the financial markets and with the
          exception of that provided for in the second paragraph of Article
          Seven, below.

Six.      On its part, T.I. undertakes, with respect to INFOSEARCH, not to sell
          all or part of the equity holdings which it owns in the company
          ORDENAMIENTOS [sic] DE LINKS ESPECIALIZADOS, S.L. without the prior
          authorization of INFOSEARCH; this is until such time as the placement
          of the shares of T.I. on the financial markets takes place.

Seven.    Finally, INFOSEARCH undertakes to assume all such obligations as, with
          respect to the transfer of shares or the offering thereof, may be
          established within the framework of the contracts for underwriting the
          public offering of shares of T.I., all of this provided that, upon the
          passage of a maximum period of one year since the placement of T.I. on
          the financial markets, INFOSEARCH may freely sell the entirety of its
          4,928,000 shares subject to no condition whatsoever.

          Without prejudice to that set forth above, through the placement of
          T.I., INFOSEARCH at all times shall have the power to be able to
          transfer the number of shares necessary in order to be able to cover
          the payment obligations, to the pertinent credit institutions,
          deriving from the financing which the credit institutions may have
          been able to grant to INFOSEARCH for the acquisition of the shares
          and, as the case may be, for the purposes of that provided for in
          Articles Nine and Twelve.

Eight.    Initially INFOSEARCH shall not have a right to hold any office on the
          board of directors of T.I., while, taking into account the value and
          know-how contributed by the partners in INFOSEARCH, the entry of a
          representative of INFOSEARCH onto the board of directors shall be
          considered upon the first renewal or expansion of the said board of
          directors.

Nine.     Infosearch indemnifies and holds T.I. harmless against any possible
          legal or financial contingency which may derive from the equity
          holdings of OLE in ADQ ADVERTISING, S.L., with Infosearch assuming
          such costs as may derive from a negotiated settlement in order to
          reach a resolution of the present relations existing between OLE and
          ADQ or between any of them and Europa Press as a result of the
          agreements contained in the articles of incorporation of ADQ.

          In order that the mentioned costs may be as low as possible the
          parties shall agree to and shall establish, by mutual agreement, in
          advance, the strategy and actions to be undertaken within OLE and ADQ
          with respect to the agreements contained in the articles of
          incorporation of ADQ.

          Without prejudice to that indicated above INFOSEARCH reserves the
          right to eliminate such contingency, reaching such accord of
          cancellation with EUROPA PRESS, in particular, as it may deem most
          appropriate for its interests. In


                                                                               4

[three sets of script initials]
<PAGE>   5

          such event T.I. shall endeavor to provide to INFOSEARCH the financing
          necessary with the pledging of the shares referred to in Article One,
          with a maturity of 60 days from the admission of the shares of T.I. to
          listing on the securities exchanges.

Ten.      The parties agree that the registered office of the company
          ORDENAMIENTO DE LINKS ESPECIALIZADOS, S.L. shall be kept in Barcelona.

Eleven.   Given that the only partners in INFOSEARCH are the natural or
          artificial persons listed below, they may be subrogated to the
          position of the company INFOSEARCH by the proportional part indicated,
          in such case assuming all of the rights and obligations deriving from
          this contract and therefore obtaining the status of partners in T.I.;
          this is to be upon prior, written communication to the other
          contracting parties.

             Listing of persons and respective percentages:
             Mr. Thierry Kern (1.5%)
             Mr. Martin Velasco (19.7%)

             ODISEA HOLDING S.A. (or "PORTAL HOLDING S.A.") (companies in the
             process of formation) (59.1%)

Twelve.   INFOSEARCH undertakes to assume the cost of incorporating into T.I.
          the clients of the present electronic mail service referred to as Ole
          Mail.

          The payment of the mentioned cost, which has been established at the
          amount of US $180,000, is to be made by means of a loan for the
          mentioned amount from T.I., which INFOSEARCH must repay within a term
          of one year from the exit of T.I. to the financial markets.

Thirteen. A violation of the covenants contained in the present Agreement, as
          well as a contravening of the acts or decisions adopted in the
          performance of the covenants, shall constitute a serious breach of the
          said Agreement and shall give rise to the pertinent compensation for
          damages.

Fourteen. For the resolution of any dispute which may arise among the parties in
          relation to the present contract and, in particular, as to its
          interpretation, validity, execution, performance or termination, the
          contracting parties submit themselves to the courts and tribunals of
          the city of Madrid thus waiving their own venue, if any.

Fifteen.  The present document shall be reduced to a public document upon the
          request of any of the signatories set forth below made to the other
          contracting parties.

Sixteen.  The content and the progress of the activities deriving from this
          Agreement shall be deemed to be within the strictest rules of
          confidentiality by both parties. In the event that it may be so agreed
          to among the parties, all publicity as to the content of this
          agreement or as to its subsequent progress shall be jointly made by
          both INFOSEARCH, T.I. and TELEFONICA.

                                   STIPULATE

One. T.I., in its capacity as owner of the entirety of the shares representing
the capital stock of the company OLE, undertakes to carry out, within a term of

increase in the capital stock of the company OLE by the amount of ONE BILLION

In addition, T.I. undertakes to carry out, within a term of six months

to the base business of the company OLE.

Two. INFOSEARCH (or a third party identified for such purpose by INFOSEARCH,
provided that the controlling shareholders thereof are the same as those of
INFOSEARCH) undertakes that, once the increases in capital stock referred to
above are carried out, it shall purchase and T.I. shall sell company equity
interests representing 8% of the capital stock of the company OLE for the price
of FOUR HUNDRED MILLION (400,000,000) Spanish pesetas.

In the event that the said acquisition by the third party indicated above is
carried out, the latter shall assume the entirety of the rights and obligations
which this document allocates to INFOSEARCH, and under the same conditions.

2.    Application of Funds and Development Plan

      The Partners undertake to make a development plan and do an analysis of
      the resources necessary for the execution of such plan as soon as
      possible.

3.    Composition of the Board of Directors

      Taking into account the value and know-how contributed by the INFOSEARCH
      Partners to the development of the business of OLE, the designation of the
      members of the Board of Directors of the Company shall not be carried out
      by means of the system of proportional representation established in the
      statutory law on companies in force. The Board of Directors shall be
      initially comprised of six directors, and it shall pertain to T.I. to
      designate four directors and to INFOSEARCH to designate two directors.

4.    Ordinary Management and Registered Office of the Company

      The Management of OLE shall continue to be performed by the present
      executive team, adding to such team those persons which T.I., by mutual
      agreement between the parties, may deem to be appropriate.

5.    Placement of the Company on the Securities Exchange

      5.1   The parties set forth their express intent to establish as the
            fundamental objective of their activity as OLE partners that of
            ensuring the listing of the shares of this company on the securities
            exchange at such time as the best price can be attained therefor,
            making their best efforts in order that this may be carried out
            prior to July in the year 2000.

            T.I. undertakes to request and obtain the listing of the shares of
            the company on the securities exchange by means of the issuance of a
            public offering for the sale of such holding in the equity of OLE as
            may constitute the legal minimum therefor, with INFOSEARCH
            undertaking to include in such public offering such equity
            interest as may proportionally pertain to it by reason of
            the percentage of the equity which it owns.

            This placement shall be carried out no later than July 31, 2001,
            unless the two parties agree on another date in writing.

            INFOSEARCH shall have the right to increase the equity interest
            which it includes in the placement up to reaching 100% of its equity
            interest. In such case T.I. shall be able to opt between reducing
            the percentage of the holding which it includes in the placement to
            the same extent and having the mentioned placement increase
            accordingly.

            This undertaking on the part of T.I. is upon the condition that the
            securities market conditions are favorable for carrying out the
            mentioned placement. In the event of a disagreement between the two
            parties as to the market conditions, an investment bank of renown
            prestige shall be designated by mutual agreement and it shall decide
            as to the mentioned market conditions. The decision of such
            investment bank shall be binding upon the two parties.

            In the event that T.I. fails to comply with the commitment indicated
            above, INFOSEARCH shall have the right to purchase up to 51% of the
            capital of OLE with a valuation of such capital at 5.000 billion
            Spanish pesetas, plus the investments made commencing from today's
            date.

      5.2   As the majority shareholder in OLE, T.I. undertakes that the
            resources necessary for the normal progress of the activities of the
            Company up to the initial placement of the equity of OLE on the
            market shall derive from the Company itself or from outside
            indebtedness, including with a guaranty from T.I.

            In the event that, due to legal and/or strategic requirements, it
            becomes necessary to carry out any restructuring of the capital of
            the company which entails contributions of capital from the
            partners, T.I. grants to INFOSEARCH, if INFOSEARCH does not fully
            cover the contribution which may pertain to it by virtue of its
            equity interest, an option right to purchase the percentage of OLE
            shares necessary in order that the equity interest of INFOSEARCH may
            reach 8% of the total capital of the company.

            INFOSEARCH shall be able to exercise the purchase option granted
            herein at any time. If INFOSEARCH exercises the purchase option,
            whether in part or in full, T.I. undertakes to sell to it such
            shares as may pertain to the option thus exercised. The price of
            sale shall be the par value of the mentioned shares and the payment
            of the price shall be made within a term of sixty days commencing
            from the exercise of the mentioned option.

            The purchase option shall expire in three years commencing from the
            date of the initial admittance of the equity of OLE to listing.

6.    Admission of New Partners

      The parties shall be able to consider the admission of new partners in OLE
      if the projection of the development plans thereof will be strategically
      strengthened by their presence. In those cases where this takes place the
      admission of other partners must always be availed of the mutual agreement
      of the present partners and, in any event, in adherence to the terms
      established in Clause 7, below.

7.    Preemptive Right Prior to the Placement on Securities Exchange

      In the event that INFOSEARCH or a company controlled by the shareholders
      thereof desires to transfer all or part of its equity interest in OLE to a
      company not controlled by the transferor T.I. shall be acknowledged to
      have a preemptive right on such equity interests in the OLE company as may
      be the subject matter of the transfer.

      The abovementioned preemptive right shall be exercised in accordance with
      the following terms and conditions:

      1.    The right may be exercised by T.I. within 60 days subsequent to the
            date when it has formal knowledge that the factual eventuality
            originating it has taken place. For such purpose INFOSEARCH
            expressly assumes the duty to formally inform T.I., as soon as
            possible, as to its intent to transfer all or part of its equity
            interests in the company OLE.

      2.    The right shall be exercised with respect to the entirety of such
            equity interests as are intended to be transferred.

      3.    The price for the equity interests, in the event that this right is
            exercised, shall be the same price as that which the third party is
            prepared to pay.

            This preemptive right is entirely reciprocal and also applies to
            INFOSEARCH in the event that T.I. intends to transfer its equity
            interest in the company OLE.

8.    Exemption from the Preemptive Right

      Such right of preemption as the charter/bylaws of the Company may
      recognize, as the case may be, shall not apply when the transfer of the
      entirety or part of the OLE equity interests is carried out by T.I. to any
      company in the Telefonica Group. The purchasing company from the
      Telefonica Group fully assumes all of the rights and obligations of the
      present contract.

      Such preemptive right as the charter/bylaws of the Company may recognize,
      as the case may be, shall not apply when the transfer of the entirety or
      part of the OLE equity interests is carried out by INFOSEARCH to any
      company controlled by the controlling shareholders of INFOSEARCH. The
      purchasing company related to INFOSEARCH fully assumes all of the rights
      and obligations of the present contract.

9.    Covenant not to Compete

      INFOSEARCH and its directly or indirectly controlling shareholders
      undertake and bind themselves not to directly or indirectly carry out
      activities relating to the providing of the services which comprise the
      company purpose of OLE and which constitute competition against it unless

      With respect to its applicability, the mentioned covenant not to compete
      is limited to the geographical scope where the company OLE may be carrying
      out its activities at any given time.

      A breach by INFOSEARCH or by its controlling shareholders of the present
      covenant not to compete shall give rise to the entitlement, in favor of
      T.I., to an option right to purchase such equity interests in the company
      OLE as INFOSEARCH may own, which, in such case, it shall be required to
      sell to T.I. if such purchase option is exercised by the latter. With
      respect to the manner of exercise, the mentioned purchase option right
      shall have terms identical to those set forth in Clause 5, above.

      the entitlement, in favor of INFOSEARCH, to an option right to purchase
      such equity interests in the company OLE as T.I. may own, which, in such
      case, it shall be required to sell to INFOSEARCH if such purchase option
      is exercised by the latter. With respect to the manner of exercise, the

contravening of the acts or decisions adopted in their performance, shall
constitute a serious breach of the said Agreement and shall give rise to the
pertinent compensation for damages.

In Madrid, on April fifteenth, nineteen hundred ninety-nine

And the party of the second part, Jose Valles Rovira, with Taxpayer I.D. #

The parties to the meeting reciprocally acknowledge adequate authority for this
act in the representatives participating and

I.    That INFOSEARCH is the holder of all corporate shares that make up the

      consultants.

IV.   That TI wishes to purchase and INFOSEARCH to sell all the shares of the
      corporation into which OLE's capital stock is divided. In order to
      finalize and carry out the respective purchase and sale of said shares,
      the parties at this meeting, modifying what was agreed upon in the
      aforementioned Agreement of March 10, 1999, as necessary, sign this sales
      agreement to that end.

                                 THEY STIPULATE

One.- In this act, INFOSEARCH sells and transfers to the buyer, TI, all the
shares of the corporation representing the company OLE, numbered 1 through 100,
par value five thousand pesetas per share, fully paid in.

      Likewise, INFOSEARCH represents and warrants that said shares are
completely free of liens, restrictions and encumbrances, that they are not
subject to any right of acquisition in favor of any third party and that they
are not subject to any judicial or administrative attachment or to any other
limitation on the free transferability of the shares.

Two. The total price of the aforementioned purchase was set at TWO BILLION
(2,000,000,000) pesetas and will be paid in the following way:

            TWO HUNDRED MILLION (200,000,000) pesetas, which TI will deliver to
            INFOSEARCH through a bank transfer to the account designated by
            INFOSEARCH, which INFOSEARCH will deem received at the time the
            Agreement referred to in Statement II is signed.

            ONE BILLION EIGHT HUNDRED MILLION (1,800,000,000) pesetas, which TI
            will transfer to the account designated by INFOSEARCH at the time
            when documental support is provided for the following items, to the
            total satisfaction of TI:

            a)    Normalization of the contingencies stated in the process of

                  intellectual property rights.

            b)    Legalization of the two loans granted by INFOSEARCH TO OLE for
                  amounts of 30,000,000.- pesetas and 150,000.- Swiss francs on
                  November 25, 1998 and March 18, 1999, respectively.

            c)    The original stock certificate of the transferred shares that
                  are the subject of this sales agreement.

            The above-mentioned amount will be paid simultaneously with the
            legalization of the sales agreement in a notarized instrument.

Three.- INFOSEARCH warrants to TI that the OLE company has not assumed any
commitment or payment obligation whatsoever as a result of holding capital stock
in the companies ADO ADVERTISING QUALITY, S.L., NET PARTNERSHIP, S.L. AND
PLATAFORMAS TEMATICAS INTERNET, S.L.

      Likewise INFOSEARCH, as the sole shareholder of OLE, will make every
effort to resolve the commitments assumed by OLE as a partner in ADO ADVERTISING
QUALITY, S.L. with the other partner of said company, Europa Press Comunicacion,
S.A.

      With respect to OLE's stake in the company NET PARTNERSHIP, S.L., the
seller [INFOSEARCH] will make every effort to verify this stake to the full
satisfaction of TI. If that is not possible, the seller promises to deliver to
OLE the full amount that the seller could obtain by divesting itself of this
stake. If the transfer is not carried out and therefore, Mr. Valles Rovira
resumes his role as shareholder of NET PARTNERSHIP, S.L., his role [in NET
PARTNERSHIP] will be exclusively a fiduciary role with respect to OLE.

      In any event, INFOSEARCH promises and guarantees full indemnification to
TI with respect to any possible legal or financial contingency that could arise,
directly or indirectly, from OLE's holdings both in NET PARTNERSHIP, S.L. and in
ADO ADVERTISING QUALITY, S.L.

Four.- INFOSEARCH likewise warrants that it has not posted collateral of any
kind on the assets of OLE, especially in connection with loans extended to OLE
by INFOSEARCH as well as any other possible debt assumed by OLE in its relations
with INFOSEARCH.

Five. The above-mentioned Agreement signed between the parties on March 10,
1999, which is incorporated into this agreement as Exhibit 1, is an integral
part thereof and is

confirmed by both parties in all its terms, except insofar as it is modified by
the clauses of this stock sales agreement.

Six. All expenses and taxes accrued because of this agreement will be paid by
the parties pursuant to the Law.

Seven. Both parties promise to maintain absolute confidentiality about the
content and details of this agreement.

Eight. The participating parties agree that all litigation, discrepancy, dispute
or claim resulting from the performance or interpretation of this agreement or
related to it, directly or indirectly, will be definitively resolved through
arbitration in the framework of the Arbitration Court [Corte de Arbitraje] of
the Madrid Chamber of Commerce and Industry [Camara de Comercio e Industria de
Madrid], which is charged with administrating arbitration and appointing
arbitrators pursuant to its regulations and bylaws.

      Likewise, the parties expressly state their commitment to comply with the
arbitration decision handed down.

      The arbitration will be equitable arbitration [arbitration ex aequo et
bono -- in which the arbitrator is not bound by legal principles, but decides
the case as seems fair to him].

      In witness whereof, both parties sign this agreement in two copies, in the
place and on the date indicated.

2.2   Pre-Emptive Right. After the one-year period described above has elapsed,
      any transfers made by TELEFONICA to third parties of its shares in TERRA

            fact in writing within ten (10) calendar days following the date on
            which the Offer was received. Said notice, together with the Offer,
            shall constitute a valid, legally binding and enforceable agreement
            to sell and purchase the Shares Offered. This option shall be
            subject to obtaining any regulatory approvals that may be needed and
            to expiry of any waiting periods required under applicable law. The
            parties agree to work together to make the presentations and obtain
            the approvals needed for TERRA to be able to exercise its rights
            under this Agreement. The sale of the Shares Offered to TERRA in
            accordance with this Section must take place at 11:00 a.m., Peruvian
            Time, at TELEFONICA'S offices or whatever other place is agreed by
            the parties on the later of the following dates (i) the tenth day
            following the date the notice sent by TERRA in which it chooses to
            purchase the Shares Offered is received, or (ii) the [tenth (10)]
            business day after all the regulatory approvals needed for said
            transaction have been obtained and any applicable waiting period has
            expired. The sale shall be completed when TELEFONICA hands over to
            TERRA the certificates representing the Shares Offered which are to
            be purchased, together with a transfer of shares, and when TERRA
            hands over to TELEFONICA the selling price thereof in cash or in the
            form of bank documents representing funds that are immediately
            available.

      2.2.2 Decision Not to Buy. In the event that TERRA were to accept only
            part of the Offer, or if the acceptance period expires without any
            statement being made that it intends to buy, the Offer shall be
            deemed to have been turned down. Only in such an event may
            TELEFONICA offer to sell the TERRA shares to third parties,

            Offered must be sold for the price and under the same or more
            onerous terms than in the Offer. Compliance with said terms must be
            checked by the respective general manager of TERRA either when or
            before the transfer takes place. If the potential third-party buyer
            fails to make the purchase within the same period of time provided
            for in the Offer to TERRA in accordance with paragraph (a) above, or
            if TELEFONICA wishes to offer its shares in TERRA at a price or
            under terms that are not as onerous as the price and terms of the
            Offer, the Shares Offered may not be sold, assigned or transferred

      identified with Voter Registration Card No. 07866791, who states that he
      has sufficient authority to enter into this agreement; hereinafter
      referred to as "TNP."

This Agreement for Divestiture of a Line of Business is entered into according
to the following terms and conditions:

ONE. - BACKGROUND

1.1   TSI is a subsidiary of Telefonica del Peru S.A.A., founded as part of the
      latter's strategy for providing value added services. For the purposes of
      this agreement, the listed services shall hereinafter be referred to as
      the "INTERNET SERVICES."

      In conducting its commercial activities, TSI provides INTERNET SERVICES,
      not including what is known as a "Portal," to two clearly defined market
      segments: (i) the market consisting of corporate customers (including
      companies using INTERNET SERVICES), and (ii) the market including
      residential customers. TSI warrants that each line of business is
      conducted independently, as demonstrated in the customer breakdown,
      listing the customers that belong to each of these market segments.

1.2   Within the overall framework of the global strategies designed for the
      various companies making up the Grupo Societario Telefonica, S.A.
      (hereinafter, referred to as the "Telefonica Group"), including the
      parties hereto, it was decided that it was in the interest of those
      concerned to develop the residential user market on an integrated basis
<PAGE>   2

      worldwide. For this reason, a decision was made to run the services to be
      offered to this market through a specific worldwide corporate sub-group,
      owed by the Telefonica Group, and to this end, TERRA NETWORKS was founded.
      TERRA NETWORKS is responsible for developing market activities in the
      various countries where the Telefonica Group operates, either directly or
      through its affiliates or subsidiaries, for INTERNET SERVICES aimed at
      residential users and small business markets, known as "small offices/home
      offices" (hereinafter, "SOHOs"). The parties understand that the growth
      strategy for these markets, as defined, will allow for economies of scale
      in the provision of INTERNET SERVICES.

1.3   TNP is an affiliate of TERRA NETWORKS devoted to providing interactive
      services over the Internet aimed at the residential user market
      (hereinafter, the "TNP Business"). TNP does not offer its value added
      activities in the corporate customer market segment.

1.4   For the purposes of this agreement, it shall be understood that the
      residential user market consists of (i) individuals who at the time of
      contracting for the INTERNET SERVICES, and for as long as they remain
      users of such services, have no intention of using the services, nor do
      they currently use them to carry out commercial activities relating to
      providing goods or services of any type; and (ii) individuals,
      telecommuters and self-employed professionals who have the intention to
      use the INTERNET SERVICES from their homes for carrying out commercial
      activities related to providing goods or services.

TWO. - REPRESENTATIONS AND WARRANTIES

2.1   In its execution of the overall strategy set by the companies making up
      the Telefonica Group, TSI agrees to restrict its activities to providing
      INTERNET SERVICES for corporate customers (for the purposes herein,
      corporate customers shall include any individual or legal entity not
      included in the definition given under paragraph 1.4). To this end, and in
      accordance with the business strategy designed by TSI, it shall cease
      developing or offering the INTERNET SERVICES to residential customers,
      hereinafter the "Business."

             nature of the above statements, TSI has no knowledge of any event
             that could materially affect the cost of operating the Business.

THREE. - PURPOSE OF THE AGREEMENT

3.1   By entering into this Agreement, TSI undertakes to make available to TNP
      so that TNP may start carrying on its business activity, the Business Unit
      consisting of the technological service platform required on signing the
      relevant trade agreements. TSI shall also transfer 1) all the contractual
      relationships it has with its customers as of the date this Agreement is
      signed, and 2) the customer databases from the Information Supplier
      Centers (CPIs or ISPs) with which it has entered into agreements for
      assigning its contractual position, which are listed in Exhibit 1. The
      telecommunications infrastructures needed for the Business Unit shall not
      be included in the definition of the Business Unit, and shall in each case
      be the object of a lease in the appropriate trade agreements entered into
      with Telefonica del Peru, S.A.A.

3.2   The Parties agree that the assets of TSI used for or emerging as a result
      of the Business that make up the technological service platform and that
      are needed for TNP to be able to carry on its activities, including, but
      not limited to, the platform required for the Housing and Hosting
      services, shall be made available to TNP for the purposes hereof, on
      signing the appropriate agreements, so that TNP may carry on the Business
      in the future under the same conditions as had been the case for TSI.
      During the first six (6) months of the term
<PAGE>   5

      of this Agreement, TSI shall provide TNP with the housing and hosting
      services over the technological service platform, it being understood that
      the remuneration for these services during that six (6) month period has
      been included in the consideration set in Clause Four hereof. The
      telecommunications infrastructures needed to conduct the TNP Business fall
      outside the scope of this paragraph and shall in each case be the object
      of a lease through the appropriate trade agreements entered into with
      Telefonica del Peru, S.A.A.

3.3   The parties agree that the term "contractual relationships," mentioned in
      Clause 3.1 above, covers the portfolio of residential users.

3.4   The sales actions aimed at formalizing the contractual relationships
      between TNP and each of TSI's current customers, as well as with the
      customers referred to in Clause 3.1 (2) above shall be TNP's
      responsibility.

3.5   The parties shall by mutual agreement draw up the procedures to be
      followed for determining the number of residential users who are to be
      served by TNP as of November 15, 1999.

      In the event that as a result of applying these procedures, the above
      number of residential users falls below 60,000 (sixty thousand) customers,
      the parties agree that TSI must compensate TNP by providing the services
      requested by TNP, which TSI shall provide, without TNP having to pay any
      amount for said services until the amount of the compensation has been
      attained.

      To this end, the amount of the compensation shall be the result of
      multiplying the difference between 60,000 and the potentially smaller
      number of users as of November 15, 1999, by US$500 (five hundred 00/100
      United States dollars), up to a limit of US$5,000,000 (five million 00/100
      United States dollars).

      The amount of the compensation so determined shall be offset against the
      remuneration that would have to be paid for the services TSI provides TNP
      under the terms of this Clause 3.5, paragraph two, bearing in mind the
      rates in force for each of the services at the time any such services are
      provided.

FOUR. - PRICE

4.1   The parties agree that the price for conveying the Business Unit shall be
      US$5,000,000.00 (five million United States dollars). This does not
      include the General Sales Tax (Impuesto General a las Ventas - IGV) or the
      Municipal Promotion Tax (Impuesto de Promocion Municipal - IPM). Both
      taxes shall be added to the price that must be paid by TNP.

4.2   The Parties likewise expressly provide that when determining the price
      they have assessed the situation of the accounts receivable that are an
      integral part of Exhibit 1. In

<PAGE>   6

      this regard, TNP fully assumes the commercial risk relating to the
      portfolio of residential users referred to in Clause 3.3, above.

4.3   TNP shall pay TSI the price in cash, in dollars, the currency of the
      United States of America, under the applicable terms of Article 1237 of
      the Civil Code.

FIVE. - FORMALIZING THE TRANSFER

5.1   The parties agree that TSI shall cooperate and collaborate at all times,
      and make every effort to effectively and fully formalize the
      aforementioned contractual relationships. When completing such work, TSI
      undertakes not to deviate from the marketing strategies and sales policies
      that are set at any time by TNP, as well as to follow its directives for
      carrying on said marketing activities on TNP's behalf.

5.2   The parties agree that TNP, as a result of the transfer governed by this
      Agreement, shall take over all the rights, obligations, responsibilities,
      profits and losses arising from or relating to the aforementioned
      customers.

SIX. - TRANSFER OF STAFF

6.1   As a result of the provisions of the above Clauses, the parties agree to
      make every effort to ensure that TSI staff attached to the Business are
      transferred and become part of TNP's work force as from the effective date
      of the transfer.

6.2   For the purposes described in Clause 6.1, above, the parties shall
      determine, by mutual agreement, the personnel involved in the activities
      of the Business, and TNP shall make every effort to ensure that the
      respective workers of TSI voluntarily agree to be transferred to TNP's
      work force. If for any reason any TSI worker attached to the Business were
      to fail to agree to be transferred to TNP's work force and this were to
      force TSI to unilaterally terminate the employment agreement with said
      worker, the cost of any severance that would have to be paid said worker
      would be met by TNP. In any case, TSI shall make every effort to reduce
      any labor-related contingencies that might arise and damage TNP's
      interests stemming from the aforementioned staff transfers.

      The Parties declare that responsibility for paying remuneration, wages,
      commissions, bonuses, social and similar benefits that have accrued up to
      the effective date of the transfer for the personnel who are transferred
      with the Business, shall be paid by TSI. In the event that, under
      applicable law, TNP were to be required to make any of these payments, TSI
      shall immediately refund the relevant amount to TNP.

SEVEN. - SURVIVAL AND RELIABILITY OF THE REPRESENTATIONS AND WARRANTIES

      TNP harmless from any loss, liability, cost, fine or expense of any kind
      directly or indirectly emerging from:

      7.1.1  Any failure to fulfill any representation, warranty or undertaking
             made by TSI as set forth herein; and

      and hold TSI harmless from any loss, liability, cost, fine or expense of
      any kind directly or indirectly arising from:

             made by TNP as set forth or envisioned herein; and

      7.2.2 Any breach or nonperformance of any agreement, undertaking or
            obligation made by TNP as set forth herein.

      for and shall be determined after recovering any insurance, real tax
      savings and recoveries from third parties.

[marginal signature]

a special General Meeting of Shareholders and it shall have to be held whenever
the Board of Directors may deem appropriate in the interests of the Corporation

stock is in attendance and those present unanimously accept that the meeting be
held.

Article 11. The General Meetings of Shareholders, both regular and special ,
shall be validly convened on first call when the shareholders present or
represented possess at least 25 percent of the subscribed capital with the right
to vote. On second call the convening of the meeting shall be valid whatever the
capital may be attending the meeting.

      That set forth in the previous paragraph notwithstanding, in order for a
regular or special General Meeting of Shareholders to be able to validly decide
to issue obligations, an increase or reduction in capital, a change in
corporation form, a merger/consolidation, a spin-off, a dissolution of the
Corporation for the reason set forth in Point No. 1 in Article 260 of the
Amended General Law of Corporations and, in general, any modification of the
charter/bylaws, there shall have to be present therein, on first call,
shareholders in attendance or represented by proxy possessing at least 50
percent of the subscribed capital stock with the right to vote, and on second
call it shall be sufficient to have the attendance of 25 percent of such
capital. When shareholders are in attendance representing less than 50 percent
of the subscribed capital stock with the right to vote the resolutions referred
to in this paragraph shall only be able to be adopted validly with the favorable
vote of two thirds of the capital present or represented by proxy in the
meeting.

Article 12. Any shareholder who has deposited his shares at the corporation
domicile at least five days in advance of the day when the meeting of
shareholders is to be held, or who substantiates, by means of the pertinent
certification setting forth the name, that he has deposited them with any
banking institution or entity authorized for the depositing of securities in
Spain, may personally attend the General Meetings of Shareholders or have
himself represented therein by another person, even if not a shareholder.

      For such purpose he shall request and obtain from the Corporation, at any
time subsequent to the publication of the notice of meeting and up to the
commencement of the meeting of shareholders, the pertinent admittance ticket.

      The Directors must attend the General Meetings of Shareholders.

Managers, executives, authorized representatives, technical specialists and
other persons who, in the opinion of the Chairman of the Meeting, should be
present at the meeting due to having an interest in the good progress of the
business of the corporation may also attend. The Chairman of the Meeting may
also in principle authorize the attendance of any other person he may deem to be
appropriate, but the meeting may revoke such latter authorization.

Article 13. The Chairman of the Board of Directors shall be the Chairman of the
General Meeting of Shareholders. The Chairman shall be assisted by a Secretary,
who shall be the Secretary of the Board of Directors.

      Prior to the consideration of the agenda of meeting a list shall be made
of those in attendance in the manner and with the prerequisites mandated by the
law.

      The Chairman shall direct the deliberations, granting the floor, in strict
order, to all such shareholders who have so requested in writing, and then to
those who so request verbally.

      Each one of the points which form part of the agenda of meeting shall be
subjected to a separate vote. The resolutions shall be adopted by a majority of
the shares present or represented by proxy in the meeting except in the case
referred to in the last indent of the last paragraph of Article 11 of the
present charter/bylaws, where the favorable vote of two thirds of the capital
present or represented by proxy in the meeting shall be required.

      Each share of the same par value shall confer the right to one vote and in
the case of shares of a different par value the principle of proportionality
between the par value of the shares and the right to vote shall always be
adhered to.

Article 14. The deliberations and resolutions of the General Meetings of
Shareholders, both regular and special, shall be set forth in minutes made or
transcribed in a Book of Minutes and they shall be signed by the Secretary with
the approval of the Chairman, or by such persons as may have acted as such in
the meeting involved. The minutes may be approved by the meeting itself as a
continuation of the holding of the meeting or, in the absence thereof, within a
term of fifteen days, by the Chairman and two examiners, one appointed by the
majority and the other by the minority.

      Upon their own initiative, the Directors, if they may so decide, and
necessarily, when it has been so requested formally in writing five days in
advance of the day envisioned for the holding of the meeting on first call by
shareholders representing at least 1 percent of the capital stock, shall require
the presence of a notary to make the minutes of the meeting, and the Corporation
shall bear the cost of the fees of the notary selected. The notarial record
shall be deemed to be the minutes of the meeting.

Article 15. The management, administration and representation of the
Corporation, before the courts and otherwise, and all of the acts included in
the corporation purpose shall pertain to the Board of Directors, which shall act
in a collegial fashion, without prejudice to such delegations and powers of
attorney it may confer.

Article 16. The Board of Directors shall be integrated by a number of Directors
not less than three nor more than eleven members.

      The determination of the actual number of Directors to integrate the Board
at any given time shall pertain to the General Meeting of Shareholders, provided
that it is between the minimum and maximum referred to in this article.

      Those persons covered by any legal prohibition shall not be able to be
appointed as Directors, especially persons covered by the incompatibilities
established in State Law

No. 12/95 of May 11 and in Law No. 14/95 of April 21, of the Assembly of the
Autonomous Community of Madrid.

      For the election of the members of the Board of Directors the provisions
contained in Article 123, et seq., of the Amended General Law of Corporations
and the supplementary rules shall apply.

      In order to be elected as a member of the Board of Directors it shall not
be required that one be a shareholder except in the case of provisional
appointment by co-option effected by the Board of Directors itself, in
accordance with that provided for in Article 138 of the said amended law.

Article 17. The Directors shall be appointed for a term of five years but they
may be reelected by the meeting of shareholders one or more times for periods of
equal duration.

      The removal of the Directors may be decided at any time by the General
Meeting of Shareholders.

Article 18. The Board of Directors shall meet when so required in the interest
of the Corporation, and necessarily within the first three months of each fiscal
year in order to formulate the accounts for the previous fiscal year and the
management report, as well as whenever it must call a General Meeting of
Shareholders, unless the latter is a universal meeting.

      It shall be called to meet by the Chairman or by such person as may
substitute for him, upon his own initiative, and necessarily in those cases
referred to in the previous paragraph, or whenever so requested by at least one
third of the Directors in office.

      The meetings of the Board of Directors shall be chaired by the Chairman
thereof. In the absence of the Chairman he shall be substituted by one of the
Vice Chairmen and, in the absence of both, the eldest Director. If the Secretary
is not in attendance he shall be substituted by the Vice Secretary and, in the
absence of the latter, the youngest full member from among those attending the
respective meeting.

      The Board of Directors shall be deemed to be validly convened when the
meeting is attended, by those present or represented by proxy, by one half plus
one of its members. If the number thereof is odd, the Board of Directors shall
be deemed to be validly convened when the meeting is attended, by those present
or represented by proxy, by a number greater than those absent. Any Director may
confer a proxy to another Director in writing expressly for the meeting
involved.

      The deliberations and debates within the Board of Directors shall take
place separately with respect to the various points contained in the agenda of
meeting established in advance or approved by the meeting itself, and they shall
be moderated by the Chairman, who shall grant the floor successively to such
Directors as may desire to take the floor. The proposals for resolutions may be
submitted in writing, or verbally during the course of the meeting. Each one of
the proposals on the points included in the agenda of meeting shall be subjected
to separate voting.

      In order to adopt resolutions it shall be necessary to have the favorable
vote of an absolute majority of the Directors in attendance at the session,
except in the case of the permanent delegation of any power of the Board of
Directors to the Executive Committee or to the Managing Director and the
designation of those Directors who are to hold such offices, where it shall be
necessary to have the favorable vote of two thirds of the members of the Board
of Directors.

      Voting in writing and without a session shall only be allowed when no
Director opposes such procedure.

      The discussions and resolutions of the Board of Directors shall be set
forth in a Book of Minutes, which may be the same as that referred to in Article
14, and each of the minutes shall be signed by the Secretary with the approval


                                        5

of the Chairman, or by such persons as may have substituted for them in the
meeting to which the minutes refer. In the cases of voting in writing and
without a session the resolutions adopted and the votes cast in writing shall
also be set forth in the Book of Minutes.

Article 20. The compensation of the Directors shall consist of a fixed, monthly
payment, the amount of which shall be decided upon by the General Meeting of
Shareholders for each year or with validity for such fiscal years as the meeting
of shareholders itself may establish, and the compensation may differ from
Director to Director.

CHAPTER FOUR - THE FISCAL YEAR, ACCOUNTING DOCUMENTS AND DISTRIBUTION OF THE
PROFITS

Article 21. The fiscal year shall commence on January 1 and shall terminate on
December 31 of each calendar year.

      By way of exception, the first fiscal year shall commence at the time of
the formation of the Corporation and shall terminate on December 31 of the same
year.

Article 22. Within a maximum term of three months commencing from the close of
each fiscal year the Board of Directors must formulate the annual accounts,
which are to include the balance sheet, the income statement and report, the
management report and the proposal for the application of the profits, as well
as, as the case may be, the consolidated management report and accounts, in
accordance with the criteria of valuation and with the structure mandated by the
statutory law in force.

      These documents, which must be signed by all of the Directors with express
indication of the reason justifying the omission of the signature of any of
them, shall be submitted, in turn, for the review of an auditor or auditors of
accounts, appointed in the manner, for the terms and with the functions provided
for in the law, for verifying the annual accounts. The General Meeting of
Shareholders, upon appointing the person or persons who are to perform the
auditing, shall determine the number thereof and the period of time during which
they shall hold office.

Article 23. Once the annual accounts are approved, in turn, by the General
Meeting of Shareholders, they shall be submitted for their filing, with the
certificate of the resolutions of the meeting of shareholders, in the


                                        7
<PAGE>   23

Commercial Register of the corporation domicile in the form and term and in
accordance with the provisions of the General Law of Corporations and the
Regulations of the Commercial Register.

Article 24. The General Meeting of Shareholders shall decide with respect to the
application of the profits of the fiscal year according to the balance sheet
approved.

      Once the applications provided for by the law or the present
charter/bylaws are covered, dividends shall only be able to be distributed
against the profits of the fiscal year or against freely disposable reserves if
the book value of the net worth does not become, as a result of the
distribution, lower than the capital stock.

      The distribution of dividends to the common shareholders shall be carried
out in proportion to the capital which they have contributed.

CHAPTER FIVE - DISSOLUTION AND LIQUIDATION OF THE CORPORATION

Article 25. The Corporation shall be dissolved in those cases and with those
prerequisites established by the law.

Article 26. The General Meeting of Shareholders which decides as to the
dissolution of the Corporation shall also appoint the receivers, who, as the
case may be, may be the previous members of the Board of Directors.

      The number of receivers shall always be odd. In cases where the meeting of
shareholders decides to appoint the former Directors as receivers and their
number had been even, the General Meeting of Shareholders shall also decide
which Director shall not be appointed to be a receiver.

      Without prejudice to that provided for in the preceding paragraph, such
shareholders as represent at least one twentieth of the capital stock and, as
the case may be, the representative or representatives of the bondholders may
apply to the judge of primary jurisdiction for the corporation domicile for the
designation of an administrator with the prerequisites and powers established by
the law.

Article 27. In the liquidation of the Corporation, the rules established in the
law and those which, supplementing them but not contradicting them, may have
been decided, as the case may be, by the General Meeting of Shareholders which
has adopted the resolution to dissolve the Corporation shall be adhered to.

Both regular and special Meetings of Shareholders shall deal with the issues

A Regular Meeting of Shareholders may address issues of any type, even if not
specifically falling within its defined purview under the Law.

Notwithstanding the above provisions, in the absence of any advance notice of a

of any type if all the capital stock is represented and those in attendance

Article 11

A first session of a regular or special Meeting of Shareholders shall be

subscribed must be in attendance or represented through proxy. For a second
session to validly decide these items, representation by 25 per cent of the

<PAGE>   5

A shareholder shall be required to have its shares on record in the associated
account ledger no later than five days prior to the date the meeting is
scheduled before it may attend the meeting.

Without prejudice to shareholders that are legal entities attending through
their authorized representatives, any shareholder entitled to attend may opt to
be represented by another party, even if that party is not a shareholder. Such
representation must be authorized in writing and specified for each Meeting. In
all cases, the provisions set forth under Article 108 of the Corporations Act
shall remain intact.

Board Members shall attend General Shareholders' Meetings. Executive Directors,
Managers, Agents, Engineers and other parties may also attend when the Chairman
of the Board feels their presence is needed because of their interest in the
proper running of the company's business. The Chairman of the Board may
authorize attendance by any other person deemed appropriate, however the Meeting
may revoke any such authorization.

Article 13

The Chairman of the Board shall also serve as Chairman of the Shareholders'
Meetings. He or she shall be assisted by a Secretary who shall be the Secretary
of the Board of Directors.

Before commencing with the agenda, the Secretary shall draw up a list of those
in attendance, indicating the nature of each or who they represent, and the
number of shares they represent. At the end of the list, the determination of
the number of shareholders attending or represented by proxy shall be given,
along with the number of shares and percentage of capital stock held.

The list of attendees may be attached to the Minutes upon signature by the
Secretary and approval from the Chairman. The list may also be drawn up as an
file or saved to an electronic medium, in which case, the type of media used
shall be indicated in the Minutes, and the proper identifying information shall
be recorded on the previously sealed sleeve of the file or media, and signed by
the Secretary with approval from the Chairman.

The Chairman shall lead the debate, granting the floor in strict order to all
shareholders who have asked to speak in writing, followed by those who have
submitted verbal requests.

Each item on the agenda shall be voted on separately. Decisions shall be adopted
by majority vote representing all shares in attendance or represented by proxy,
except in the cases referred to in the final sentence of the last paragraph of
Article 11 of these Bylaws, which shall require the affirmative vote of two
thirds of the capital in attendance or represented at the Meeting.

Each share having the same par value shall be entitled to one vote. When there
are shares having differing par values, voting rights shall in all cases be
determined proportionally according to the par value of the shares.


                                                                               5
<PAGE>   6

Article 14

Minutes shall be taken to record any debate and decisions made at both regular
and special Shareholders' Meetings, and these shall be attached or transcribed
in a special Record Book. The Chairman and Secretary of record, or whoever may
be acting on their behalf at any given meeting, shall sign the Minutes.
Shareholders may approve the Minutes at the close of the Meeting, or lacking
that, the Chairman and two Participating Auditors, one appointed by the majority
and the other by the minority, shall approve them no more than fifteen days
following the date of the meeting.

The Board Members may require that a Notary attorney attend the meeting to draw

2.1. With this Agreement TI and AMADEUS intend to establish a jointly owned
company with the objective of establishing a travel-focused website. This
website will provide news, reports, destination information, and on-line
purchase facilities for travel and travel-related products.

Said jointly owned company will be the only travel-oriented component seamlessly
integrated in the overall "internet hubs" being developed by TI. Said Internet
hub aims to target the Spanish and Portuguese speaking markets with the
provision of content and e-commerce services.

The main target customers will be Spanish and Portuguese speaking customers
based in Spain, Portugal and Latin American countries listed in Attachment B.

In particular, the jointly owned company's website will encompass:

            fare and reservations on air, hotel, and car services, including
            access to negotiated fares and special offers. Additional providers
            will be added as they become available through AMADEUS web products,
            or as they are specifically developed for the jointly owned company
            (for instance, local railways and ferries). Sales of tour operator
            packages and cruise services may also initially be offered via
            e-mail and/or call centers.

      (ii)  Information content related to travel that will initially be
            purchased, provided by both Parties and later on will be
            complemented by the jointly owned company's own editorial/content
            management activity. This content will include (but will not be

      In accordance with the provisions of the Master Agreement executed on July
23rd, 1999 between Amadeus Global Travel Distribution, S.A. ("Amadeus") and
Terra Networks, S.A. ("Terra" - formerly, Telefonica Interactiva, S.A.), both
Parties had seventy five (75) days of signature of such Master Agreement to
conclude certain requirements.

      Today the aforementioned term finishes and, although preliminary actions
have been taken, the Parties have not yet reached the requirements within the
initial term.

      Therefore, assuming that both Parties equally cause this delay over such
initial term, it would be necessary that both Parties, by means of their
acceptance and signature of this letter, expressly amend and extend the initial
term with fifteen additional days. Both Parties expect this new term to be
sufficient to conclude the negotiations and to agree with the final drafting of
their respective agreements with NewCo.

      For this purpose, we signed this letter as proof of our approval of this
extension of the term to conclude the agreements with the NewCo.

      In accordance with the provisions of the Master Agreement executed on July
23rd, 1999 between Amadeus Global Travel Distribution, S.A. ("Amadeus") and
Terra Networks, S.A. ("Terra" - formerly, Telefonica Interactiva, S.A.), both
Parties had seventy five (75) days of signature of such Master Agreement to
conclude certain requirements.

      By means of Letter signed by Amadeus and Terra last 6th of October, the 75
days period was extended two weeks ending the 20th of October 1999.

      Today the aforementioned extension finishes and, although additional
actions have been taken, the Parties have not yet completely reached all the
requirements within the agreed extended term.

      Therefore, assuming that both Parties equally cause this delay over such
initial term, it would be necessary that both Parties, by means of their
acceptance and signature of this letter, expressly amend and additionally extend
the term until the 31st of December, 1999. Both Parties expect this new term to
be sufficient to conclude the negotiations and to agree with the final drafting
of their respective agreements with the new joint venture company and to
complete the basic guidelines of the budget and business plan of the new joint
venture company.

      For this purpose, we signed this letter as proof of our approval of the
extension of the term as described above.

<PAGE>   2

                                   BACKGROUND

ONE. - ON TELEFONICA, TSI AND TNP

1.1   TELEFONICA is a publicly held corporation dedicated to providing a wide
      range of public telecommunications services in Peru, either directly or
      indirectly through its subsidiaries. These services include long distance
      carrier services, local fixed phone service (domestic and international),
      cable television service, and mobile telephony service, among others.
      TELEFONICA disposes of all administrative licenses required for carrying
      out the activities listed in this paragraph.

1.2   TSI is a subsidiary of TELEFONICA, founded as part of the latter's
      strategy for providing value added services. For the purposes of this
      agreement, the listed services shall hereinafter be referred to as the
      "Internet Services."

      In conducting its commercial activities, TSI provides Internet Services
      (hereinafter, for the purposes of this agreement, the listed services
      shall be referred to as the "INTERNET SERVICES"), not including what is
      known as a "Portal," to two clearly defined market segments: (i) the
      market consisting of corporate customers (including companies using
      INTERNET SERVICES), and (ii) the market including residential customers.
      TSI warrants that each line of business is conducted independently, as
      demonstrated in the customer breakdown, listing the customers that belong
      to each of these market segments.

1.3   Within the overall framework of the global strategies designed for the
      various companies making up the Grupo Societario Telefonica, S.A.
      (hereinafter, referred to as the "Telefonica Group"), including the
      parties hereto, it was decided that it was in the interest of all
      concerned to develop the residential user market on an integrated basis
      worldwide. For this reason, a decision was made to run the services to be
      offered to this market through a specific worldwide corporate sub-group,
      owed by the Telefonica Group, and to this end, TERRA NETWORKS was founded.
      TERRA NETWORKS is responsible for developing market activities in the
      various countries where the Telefonica Group operates, either directly or
      through its affiliates or subsidiaries, for INTERNET SERVICES aimed at
      residential users and small business markets, known as "small offices/home
      offices" (hereinafter, "SOHOs"). Telefonica and the other parties
      understand that the growth strategy for these markets, as defined, will
      allow for economies of scale in the provision of INTERNET SERVICES.

1.4   TNP is an affiliate of TERRA NETWORKS devoted to providing interactive
      services over the Internet aimed at the residential user market
      (hereinafter, the "TNP Business"). TNP does not offer its value added
      activities in the corporate customer market segment.

1.5   For the purposes of this agreement, it shall be understood that the
      residential user market consists of (i) individuals who at the time of
      contracting for the INTERNET SERVICES, and for as long as they remain
      users of such services, have no intention of using the services, nor do
      they currently use them to carry out commercial activities related to
      providing goods or services of any type; and (ii) individuals,
      telecommuters and self-
<PAGE>   3

      employed professionals who have the intention to use the INTERNET SERVICES
      from their homes for carrying out commercial activities related to
      providing goods or services.

TWO. - REPRESENTATIONS AND WARRANTIES

2.1   In its execution of the overall strategy set by the companies making up
      the Telefonica Group, TELEFONICA, understanding it to be in its best
      interest, has therefore decided to restrict its activities to providing
      INTERNET SERVICES for corporate customers (for the purposes herein,
      corporate customers shall include any individual or legal entity not
      included in the definition given under paragraph 1.5). To this end, and in
      accordance with the business strategy designed by TELEFONICA, it shall
      cease developing or offering Internet Services to residential customers.

2.2   In view of the Parties' shared interests, they are entering into this
      Agreement for the Provision of Services under the terms and conditions set
      forth below.

                        PURPOSE AND TERM OF THE AGREEMENT

THREE. - RULES GOVERNING CONTENT

By entering into this Agreement, TELEFONICA agrees to institute or not to
institute on TNP's behalf the services listed below. In exchange for these
services, TNP shall be obligated to pay TELEFONICA the amount indicated under
Clause Six, paragraph 6.1 herein.

The services TELEFONICA will perform on TNP's behalf are listed below:

3.1   Service to be performed - TELEFONICA shall provide the telecommunications
      services to TNP that it needs to carry out its activities, and it shall do
      so as a whole under the most favorable terms it offers.

3.2   Service to be performed - TELEFONICA shall grant TNP, either directly or
      through its subsidiaries, the right to use its cable broadcast network
      under the terms mutually agreed upon in the respective contracts, so that
      TNP may offer the TNP Business to users of the cable broadcast service.

3.3   Service not to be performed - By this agreement, TELEFONICA promises TNP
      that it will not set up INTERNET SERVICES, either directly or through its
      affiliates or subsidiaries, aimed at residential users.

Both Parties to the Agreement expressly agree that the effective performance of
the services to be performed by TELEFONICA, as mentioned under paragraphs 3.1
and 3.2 of this Clause, shall give rise to TNP's obligation to pay, in addition
to the consideration it undertakes herein, the specific remuneration on a case
by case basis that the parties may agree to from time to time.
<PAGE>   4

The Parties expressly warrant that in no case may it be construed hereby that
TELEFONICA assigns any real or moveable property, whether it be tangible or
intangible, or liabilities or contractual relationships related to any type of
business (in particular, the INTERNET SERVICES). This agreement does not imply
that any agreement will be entered into for the sale or purchase of assets or
the conveyance of business between TELEFONICA and TNP.

FOUR. - TERM OF THE AGREEMENT

This agreement shall extend for a term of ten years following the date of its
execution.

FIVE. - AUTOMATIC RENEWAL

In the absence of any notice to terminate the agreement given by either Party no
later than fifteen (15) days prior to the expiration of the term or any
extension thereto, the agreement shall be successively and automatically renewed
for additional terms of one year each.

                   RELATIONSHIP AND OBLIGATIONS OF THE PARTIES

SIX. - OBLIGATIONS OF TNP

The Parties agree that TNP shall have the obligations set forth below:

6.1   To pay consideration in a single payment amounting to and under no
      circumstances less than the amount of US$25,000,000 (twenty-five million
      00/100 United States dollars).

      The consideration referred to in this section shall include neither the
      General Sales Tax (Impuesto General a las Ventas - IGV) nor the Municipal
      Promotion Tax (Impuesto de Promocion Municipal - IPM). Both taxes shall be
      added to the consideration that must be paid by TNP. Likewise, in the
      event that on the payment date any tax were to be levied on the
      consideration, said tax shall be paid entirely by TNP, even when the
      taxpayer or the economic subject were TELEFONICA, in which case, the
      consideration must be readjusted so that TELEFONICA is always paid the
      amount agreed in the previous paragraph.

      TNP undertakes to pay the consideration no later than December 15, 1999.
      The payment shall be made in cash in United States dollars in accordance
      with the terms of Article 1237 of the current Civil Code.

6.2 To pay the consideration by making a deposit to the TELEFONICA bank account:

            Beneficiary:      Telefonica del Peru, S.A.A.
            Account Number:
            Bank:
            Address:
            ABA Number:
<PAGE>   5

6.3   Not to offer for its own account, either directly or indirectly, or to
      hold shares in legal entities or take part in associations that offer or
      develop INTERNET SERVICES for customers other than residential users.

      To this end, TNP shall not be allowed to provide or offer INTERNET
      SERVICES, either on its own or through branches or subsidiaries, to third
      parties other than those included in the market segment consisting of
      residential users, nor shall it be a partner, shareholder or member in any
      kind of association, corporation or business collaboration agreement that
      provides INTERNET SERVICES to third parties other than those included in
      the market segment consisting of residential users. The ban set out in
      this paragraph affects the entire territory of Peru only and does not
      include the TNP Business.

      In the event that TNP wishes to provide INTERNET SERVICES for customers
      other than those included in the residential user market segment, it must
      apply to TELEFONICA for the appropriate permission. The appropriate
      permission must be set out in writing and signed by both Parties.

6.4   TNP also undertakes not to develop or take part, whether directly or
      indirectly, in any business, corporation, association or group whose
      purpose is to provide telecommunications services that at any time are or
      may be in competition with those provided by TELEFONICA. In the event that
      TNP were to intend to carry on any business that is likely to compete with
      the services provided directly or indirectly by TELEFONICA, it must apply
      to TELEFONICA for permission, and TELEFONICA may decide, entirely at its
      own discretion, whether or not there might be any conflict of competition
      arising out of its contractual relationship with the TELEFONICA Group.
      Depending on the case, TELEFONICA shall either bar TNP from carrying on
      such business or else set the most suitable corporate structure and
      conditions for avoiding the competition conflicts described above.

6.5   To use only the telecommunications infrastructure and services provided by
      TELEFONICA and/or its affiliates and subsidiaries and which TNP needs to
      contract and use in order to carry on its activities, under the terms laid
      down in Clause Three, paragraphs 3.1 and 3.2 and in the next to last
      paragraph of Clause Three hereof. Accordingly, TNP shall, under the terms
      hereof, be prevented from contracting for use of such telecommunications
      infrastructures and services with any suppliers other than TELEFONICA and
      its respective affiliate or subsidiary companies, provided that they are
      offered on terms that are economically and technologically competitive.
      Should this not be the case, the parties shall jointly agree on the best
      way of attaining such conditions. In the event that TELEFONICA were not to
      provide the services that may at any time be required by TERRA, the
      parties shall make every effort to implement said services as quickly as
      possible.

SEVEN. - OBLIGATIONS OF TELEFONICA

The Parties agree that TELEFONICA shall have the obligations set forth below:

To this end, TELEFONICA shall not be allowed to provide INTERNET SERVICES,
either on its own or through branches or subsidiaries, to third parties in said
market segment. The ban set out in this paragraph affects the entire territory
of Peru.

In the event that TELEFONICA wishes to provide INTERNET SERVICES for customers
in the residential user market segment, it must apply to TNP for the appropriate
permission. The appropriate permission must be set out in writing and signed by
both Parties.

EIGHT. - OBLIGATIONS OF TERRA NETWORKS

The Parties agree that TERRA NETWORKS shall have the obligations set forth below
in reference to the territory of Peru:

8.1   Not to offer for its own account, either directly or indirectly, INTERNET
      SERVICES for customers other than residential users.

      To this end, TERRA NETWORKS shall not be allowed to provide or offer
      INTERNET SERVICES, either on its own or through branches or subsidiaries,
      to third parties other than those included in the market segment
      consisting of residential users. The ban set out in this paragraph affects
      the entire territory of Peru only.

      In the event that TERRA NETWORKS wishes to provide INTERNET SERVICES for
      customers other than those included in the residential user market
      segment, it must apply to TELEFONICA for the appropriate permission. The
      appropriate permission must be set out in writing and signed by both
      Parties.

8.1   TERRA NETWORKS also undertakes not to develop or take part, whether
      directly or indirectly, in any business, corporation, association or group
      whose purpose is to provide telecommunications services that at any time
      are or may be in competition with those provided by TELEFONICA. In the
      event that TERRA NETWORKS were to intend to carry on any business that is
      likely to compete with the services provided directly or indirectly by
      TELEFONICA, it must apply to TELEFONICA for permission, and TELEFONICA may
      decide, entirely at its own discretion, whether or not there might be any
      conflict of competition arising out of its contractual relationship with
      the Telefonica Group. Depending on the case, TELEFONICA shall either bar
      TERRA NETWORKS from carrying on such business or else set the most
      suitable corporate structure and conditions for avoiding the competition
      conflicts described above.

8.2   To use only the telecommunications infrastructure and services provided by
      TELEFONICA and/or its affiliates and subsidiaries and which TERRA NETWORKS
      needs to contract and use in order to carry on its activities, under the
      terms laid down in Clause Three, paragraphs 3.1 and 3.2 and in the next to
      last paragraph of Clause Three hereof. Accordingly, TERRA NETWORKS and its
      affiliate or subsidiary companies operating in Peru shall, under the terms
      hereof, be prevented from contracting the use of
<PAGE>   7

      such telecommunications infrastructures and services with any suppliers
      other than TELEFONICA and its respective affiliate or subsidiary
      companies.

NINE. - NATURE OF THE SERVICES PROVIDED

The Parties expressly state that the services provided that are the object of
this Agreement shall under no circumstances imply any transfer of secret or
other knowledge of a technical, economic, financial or any other nature
regarding TELEFONICA'S commercial or industrial experience. Thus, this Agreement
shall not entitle any of the parties to be paid royalties under any heading.

TEN. - RELATIONSHIP BETWEEN THE PARTIES

The Parties expressly agree that this Agreement, by its very nature, does not
give rise to any labor-related rights or benefits between the contracting
parties, nor between the contracting parties and the workers and/or employees of
all the other contracting parties. Accordingly, each Party must pay their
remuneration and social security contributions and benefits.

ELEVEN. - CONFIDENTIALITY

The Parties expressly agree that all the information provided by TNP to
TELEFONICA during the term of this Agreement, relating to its business, shall be
deemed to be confidential. TELEFONICA, therefore, agrees to keep such
information confidential and not to disclose it, and to do so with the care that
it normally uses to safeguard its own information of similar importance.

Thus, TELEFONICA may not, under any circumstances, use such information for its
own benefit or disclose it to third parties, either while this Agreement is in
force or after it terminates.
