its Ownership Percentage (a "Nonlending Shareholder"), the Shareholders that
make loans ("Lending Shareholders") shall have the right to make additional
loans (totaling the amount of the loan not made by the Nonlending Shareholder),
each in the proportion its Ownership Percentage bears to the total Ownership
Percentage of the Lending Shareholders.

         Section 2.4 Mechanism for Funding Cash Calls. If the Interativa Board
authorizes a Contribution, Interativa shall send a Cash Call Notice to each of
the Shareholders calling for Contributions from such Shareholder. Each
Contribution (or portion thereof) required to be made by any such Shareholder
shall be payable by such Shareholder in the form of a capital contribution
and/or a Shareholder loan to Interativa (which form shall be the same for all
Shareholders) as determined by the Interativa Board and specified in the Cash
Call Notice. Each Contribution made pursuant to this Agreement shall be payable
by the Shareholders in cash, in Dollars, on the date specified in the Cash Call
Notice, by wire transfer to the account or accounts of Interativa as specified
in such Cash Call Notice.

         Section 2.5 Funding Obligations. Except as provided in Section 2.2
hereof, no Shareholder shall have any obligation pursuant to this Agreement to
make any capital contributions or Shareholder loans to Interativa. Failure by a
Shareholder to subscribe to its Proportionate Amount of any Contribution (other
than pursuant to Section 2.2) shall result in a dilution of its Ownership
Percentage and shall not constitute an Event of Default hereunder.

         Section 2.6 Preemptive Rights.

                  (a) Each Shareholder shall have preemptive rights, as
described below, to subscribe in proportion to its respective Ownership
Percentage in Interativa (its "Proportionate Amount") for any additional Shares
of Interativa that may be issued (including Shares to be issued pursuant to a
Cash Call Notice) to satisfy Interativa's anticipated cash needs.

                  (b) Any new Shares of Interativa from time to time to be
created, or Shares already authorized but not issued, shall, before they are
issued to satisfy Interativa's anticipated cash needs, be offered to each
Shareholder in its respective Proportionate Amount.

                  (c) Every offer regarding preemptive rights (each a
"Preemptive Offer") shall be made in writing by Interativa to each Shareholder,
shall be accompanied by forms of application for use by each such Shareholder in
applying for its Proportionate Amount or for any lesser number of Shares, and
for any Shares in excess of its Proportionate Amount, to which it is prepared to
subscribe ("Excess Shares"), and shall specify:

                           (i) the aggregate number and type (including all
material terms) of Shares that Interativa proposes to allot;

                           (ii) the terms (including the price per Share and
terms of payment) on which Interativa proposes to allot the Shares;

                           (iii) each Shareholder's Proportionate Amount.

                  (d) Every Preemptive Offer shall be open for acceptance in
whole or in part for a period of thirty (30) days from the date of its delivery
(the "Preemptive Period"). An acceptance of an offer shall only be valid to the
extent that payment in full or an irrevocable commitment to pay for the Shares
accepted, on the terms set forth in the Preemptive Offer, accompanies the
acceptance. The payment for the Excess Shares subscribed shall be made as
specified in the Preemptive Offer, and failure to comply therewith shall
preclude such Shareholder from subscribing for such Excess Shares.

                  (e) At the expiration of the Preemptive Period, Interativa
shall allot the Shares in the following manner:

                           (i) each Shareholder shall be allotted its
Proportionate Amount or such lesser number of Shares that it has accepted;

                           (ii) if the number of unaccepted Shares is less than
the number of Shares for which excess applications have been made, the
unaccepted Shares shall be allotted (as nearly as may be) in proportion to the
number of Shares held by each of the Shareholders that subscribed to Excess
Shares at the date of the Preemptive Offer; and


                                       8
<PAGE>   12

                           (iii) if the number of unaccepted Shares is equal to
or greater than the number of Shares for which excess applications have been
made, a Shareholder who has applied for Excess Shares shall be allotted the
number of Excess Shares for which it applied.

                  (f) The resolution of the Board authorizing the increase of
the share capital pursuant to Section 2.3 shall provide that if the entire share
capital increase is not subscribed to by the Shareholders, the share capital
increase may be decreased to the amount actually subscribed.

                  (g) If the Shares shall not be capable, without division into
fractions, of being offered to or divided among the Shareholders in the
proportions above-mentioned, the same shall be offered to or divided among the
Shareholders to achieve a distribution as close as possible to such proportions,
and any balance shall be offered to or divided among the subscribing
Shareholders in such manner as may be determined by the subscribing
Shareholders.

         Section 2.7 Purposes. Unless the Shareholders otherwise unanimously
agree, the businesses to be engaged in by Interativa shall be providing Internet

QUALCOMM, Vesper S.A., and Vesper Sao Paulo S.A. may each appoint an alternate
Observer. The Observers shall be entitled to receive all notices and information

                  (a) Designation. The Interativa Board shall designate one of
its members as chairman of the Board (the "Chairman") for a term of one (1)

to cast an additional vote in the event of a tie vote at any Board meeting.

<PAGE>   24

                           (xv) any equity capital increase at any Company in
excess of that set forth in such Company's approved business plan.

provided, however, that in the event any Shareholder is a Defaulting
Shareholder, the actions set forth in (i) - (xv) above shall not require the
affirmative vote of such Defaulting Shareholder until such time, if any, as such
Defaulting Shareholder is no longer in default of its obligations under this
Agreement.

                  (c) Agenda. The agenda for all meetings of the Shareholders of
Interativa shall include any item proposed by BCI or VeloCom to be placed

                                   ARTICLE VI.
                    RESTRICTIONS ON TRANSFER AND ENCUMBRANCE

         Section 6.1 Encumbrance of Shares. Either Shareholder may, without
obtaining the other Shareholder's consent, pledge a security interest in such
Shareholder's Shares in connection with any financing solely implemented by such
Shareholder; provided, however, (i) that the secured parties to which such
pledge is granted shall be institutional lenders (including bondholders) , (ii)
in the event that such secured parties, through a foreclosure or otherwise,
become the holders of the Shares, any transfers by such secured parties of such
Shares or other interests shall be subject to the transfer restrictions set
forth herein and (iii) such secured parties shall agree to be bound by this
Agreement; and provided, further, that in the event that the Shareholder
desiring to so pledge its interests is unable, using its commercially reasonable
efforts, to obtain the agreement of the secured parties to the provisions
described in clause (ii) above, the other Shareholders shall in good faith
cooperate with the pledging Shareholder and its lenders to reach a mutually
satisfactory resolution.

         Section 6.2 Transfers Subject to Restrictions.

                  (a) Restrictions. Except as set forth in this Agreement or
unless the Shareholders shall otherwise agree, a Shareholder shall not transfer
any Shares that it owns unless such transfer complies with all the requirements
of this Agreement. If a Shareholder transfers any of its Shares without
complying with the requirements of this Agreement, then such transfer shall be
null and void and such Shares shall not be registered in the name of the party
or parties to whom the Shares are to be transferred. Unless the Shareholders
shall otherwise agree, any transferee of Shares pursuant to this Agreement shall
take and hold


                                       21
<PAGE>   25

such Shares subject to this Agreement and to all obligations and restrictions
upon the Transferring Shareholder set forth in this Agreement and, in the event
such transferee is not a Shareholder, such transferee shall become a party to
this Agreement pursuant to agreements and instruments in form and substance
reasonably satisfactory to the Nontransferring Shareholder. As used in this
Article VI and elsewhere in this Agreement with respect to any Shares,
"transfer" shall mean and include any sale, exchange, gift and any other
disposition of any kind (other than any disposition referred to in Section 6.1,
but including the exercise of any remedies relating to any Lien), whether
voluntary or involuntary, affecting title to, interest in or possession of any
shares.

                  (b) Prior Notification. Upon the commencement of formal
commercial negotiations involving the direct or indirect transfer of any Shares
(including the transfer of any shares in any Affiliate that directly or
indirectly holds Shares), each Shareholder agrees to notify the other
Shareholders.

         Section 6.3 Right of First Negotiation.

                  (a) Offer Notice. Except as provided in Section 6.4, no
Shareholder shall transfer, offer to transfer, or accept an offer to transfer,
any Shares unless the Transferring Shareholder shall have provided a written
notice to each of the other Shareholders of such Shareholder's desire to
transfer Shares (the "Offer Notice") which: (i) sets forth such Transferring
Shareholder's intention to transfer some or all of its Shares (the "Offered
Shares"); (ii) specifies the consideration to be received by such Transferring
Shareholder in exchange for such Offered Shares; and (iii) indicates the number
of Shares that such Transferring Shareholder proposes to transfer.

                  (b) Right of Negotiation. Upon receipt of the Offer Notice in
accordance with Section 6.3(a), each Nontransferring Shareholder shall have
thirty (30) days (the "Negotiation Period") within which to negotiate with the
Transferring Shareholder regarding the terms of the sale of such Nontransferring
Shareholder's "Pro Rata Portion" of the Offered Shares. A Nontransferring
Shareholder's Pro Rata Portion of any Offered Shares will be equal to the number
of shares obtained by multiplying the total number of Offered Shares by a
fraction, the numerator of which shall be the number of Shares owned by such
Nontransferring Shareholder and the denominator of which shall be the total
number of Shares outstanding, excluding the Offered Shares. If an agreement is
reached, the electing Nontransferring Shareholder and the Transferring
Shareholder (or its relevant Affiliate) shall, as promptly as practicable, but
in no event later than thirty (30) days from the date of termination of the
Negotiation Period, prepare and enter into the documentation necessary to
provide for such transfer (including, if necessary, any modification or
amendment to this Agreement). If less than all of the Offered Shares are
purchased by the Nontransferring Shareholders, the remaining Offered Shares
shall be reoffered by the Transferring Shareholder to the Nontransferring
Shareholder(s) that purchased their full Pro Rata Portion of the Offered Shares
upon the terms set forth in this Section, except that such Nontransferring
Shareholders must exercise their purchase rights within two (2) Business Days
after receipt of such reoffer. If the Nontransferring Shareholders do not elect
to purchase all of the Offered Shares or if the necessary documents to effect
the transfer of any of the Offered Shares are not completed within


                                       22
<PAGE>   26

thirty (30) days of the Negotiation Period, then the Transferring Shareholder
shall be free to consummate the transfer of the Offered Shares at or above the
Floor Price (as defined below). If the Transferring Shareholder (or its relevant
Affiliate) does not consummate the transfer of the Offered Shares at or above
the Floor Price within one hundred twenty (120) days from the end of the
Negotiation Period, then the Offer Notice shall be deemed to be canceled, and
any subsequent attempt by the Transferring Shareholder (or its relevant
Affiliate) to transfer the Offered Shares must comply with all of the provisions
of this Article VI.

                  (c) Floor Price. The "Floor Price" for any given Negotiation
Period shall be equal to either (A) if an agreement was reached concerning a
price, the greater of (i) the price contained in the Offer Notice, and (ii) the
highest price agreed upon by the Transferring Shareholder and any
Nontransferring Shareholder during the relevant Negotiation Period, or (B) if no
agreement was reached concerning a price, the last price offered by the
Transferring Shareholder to any Nontransferring Shareholder during the
Negotiation Period.

         Section 6.4 Right of First Refusal.

                  (a) Limitations. No Shareholder will sell any Shares for a
price below the Floor Price except in accordance with this Section 6.4.

                  (b) Bona Fide Offer. The Transferring Shareholder must obtain
a Bona Fide Offer from a third party and must, within five (5) days of its
receipt, provide a copy of the Bona Fide Offer to each of the Nontransferring
Shareholders and to the Chief Executive Officer, along with a notice ("First
Refusal Notice") that shall contain the following representations:

                           (i) that the Transferring Shareholder is willing and
able to accept the Bona Fide Offer on its terms;

                           (ii) that the Bona Fide Offer complies with the terms
of this Agreement;

                           (iii) the names of the principal registered and
beneficial shareholders (if available), officers and directors, and any other
available information regarding the financial capacity, of the third party; and

                           (iv) that the price stated in the Bona Fide Offer is
the total consideration to be paid for the Bona Fide Shares, and that the
Transferring Shareholder is not a party to or the beneficiary of any other
agreements that would have the effect of reducing such consideration.

                  (c) Transfer of Control. For purposes of this Article VI, a
Bona Fide Offer for the transfer of control (as defined in the definition of
Affiliate) of: (i) any Shareholder; (ii) any direct or indirect parent of such
Shareholder up to, but not including, the Parent Shareholder of such
Shareholder; or (iii) an Affiliate of such Shareholder having


                                       23
<PAGE>   27

acquired Shares pursuant to Section 6.5, to a transferee that is not an
Affiliate of any of the parties in 6.4(c)(i) through (iii) above, shall be
deemed to be a Bona Fide Offer to sell the Shares held by such Shareholder, and
(ii) "Bona Fide Offer" shall mean an unconditional (other than customary closing
conditions such as receipt of governmental approvals and legal opinions and
accuracy of representations and warranties) cash offer, payable on the date of
the proposed transfer, from a Person who (A) is not an Affiliate of the
Shareholder receiving such offer, (B) has furnished financial information, if
requested by any Shareholder, to demonstrate that such Person has the financial
capacity to make a purchase pursuant to the offer, (C) is permitted to make such
purchase under applicable law and (D) agrees to assume the obligations of the
Transferring Shareholder under this Agreement pursuant to Section 6.2(a). A Bona
Fide Offer pursuant to this Section 6.4(c) shall be deemed to have been made at
the Valuation Price, as determined pursuant to Section 6.4(e).

                  (d) Mechanics. Upon receipt of the First Refusal Notice in
accordance with Section 6.4(b), each Nontransferring Shareholder shall have an
irrevocable and exclusive option, but not the obligation, to purchase its Pro
Rata Portion of the Shares covered by the Bona Fide Offer (the "Bona Fide
Shares") for the same aggregate cash consideration and on the same terms and
conditions as are specified in the Bona Fide Offer. Such option may be exercised
by any Nontransferring Shareholder only if it provides written notice of its
election to exercise such option to the other Shareholders, including the
Transferring Shareholder, on or prior to the 30th day after the delivery of the
First Refusal Notice (such 30-day period shall be referred to as the "Acceptance
Period"). The electing Nontransferring Shareholder and the Transferring
Shareholder (or its relevant Affiliate) shall, as promptly as practicable, but
in no event later than ninety (90) days from the end of the Acceptance Period,
prepare and enter into the documentation necessary to provide for such transfer
(including, if necessary, any modification or amendment to this Agreement). If
less than all of the Bona Fide Shares are purchased by the Nontransferring
Shareholders, the remaining Bona Fide Shares shall be reoffered by the
Transferring Shareholder to the Nontransferring Shareholder(s) that purchased
their full Pro Rata Portion of the Bona Fide Shares upon the terms set forth in
this paragraph, except that such Nontransferring Shareholders must exercise
their purchase rights within two (2) Business Days after receipt of such
reoffer. If the Nontransferring Shareholders do not elect to purchase the Bona
Fide Shares, then the Transferring Shareholder shall be free to consummate the
transfer of all, but not less than all, of the Bona Fide Shares only in
accordance with the terms of the Bona Fide Offer. If the Transferring
Shareholder (or its relevant Affiliate) does not consummate the transfer of the
Bona Fide Shares in accordance with the terms of the Bona Fide Offer within
ninety (90) days from the end of the Acceptance Period, then the Bona Fide Offer
shall be deemed to be canceled, and any subsequent attempt by the Transferring
Shareholder (or its relevant Affiliate) to transfer the Bona Fide Shares must
comply with all of the provisions of this Article VI.

                  (e) Valuation Price. For purposes of establishing the purchase
price of the Shares to be transferred pursuant to Section 6.4(c), Interativa
shall engage two independent and internationally recognized accounting or
investment banking firms (the "Experts"). The Experts shall confirm in writing
to the Chief Executive Officer that they do not have a conflict of interest with
the Transferring Shareholder. Following receipt


                                       24
<PAGE>   28

by the Chief Executive Officer of such written confirmation, the Experts shall
be engaged by Interativa, and shall be directed to determine the fair market
value per Share as a going concern of Interativa as a whole without taking into
account any minority discount or control premium and taking into account the
different subscription and redemption values, as the case may be, of each class
of Shares (the "Valuation Price") within thirty (30) days following their
acceptance of the engagement. The Experts shall deliver their written
determination of the Valuation Price to the Chief Executive Officer and the
Shareholders. If the higher of the Valuation Prices, as determined by the
Experts, is within five percent (5%) of the other, the "Adjusted Valuation
Price" shall be the average of the two Valuation Prices. If the higher of the
Valuation Prices is not within five percent (5%) of the other, a third Expert
shall determine the Adjusted Valuation Price. The Adjusted Valuation Price shall
be the average of the closest two among the three Valuation Prices. The Chief
Executive Officer shall deliver a copy of such written determination of the
Adjusted Valuation Price to the Transferring Shareholder and each of the other
Shareholders. Such written determination shall be final and binding on
Interativa and all Shareholders.

         Section 6.5 Transfers to Affiliates. Notwithstanding the provisions of
this Article VI, a Transferring Shareholder may transfer its Shares to any
Affiliate at any price if: (i) such Transferring Shareholder has provided thirty
(30) days' prior written notice of such transfer to each of the Nontransferring
Shareholders; (ii) such Affiliate is not in receivership, bankruptcy,
insolvency, dissolution, liquidation or any similar proceeding; and (iii) the
Transferring Shareholder agrees, pursuant to instruments in form and substance
reasonably satisfactory to the Nontransferring Shareholders, to remain liable,
as a guarantor, for compliance by the transferee with all of the obligations of
the Transferring Shareholder under this Agreement, unless the transferee, in the
reasonable assessment of the Nontransferring Shareholders, has sufficient
financial capacity to assume such obligations. If, pursuant to this Section 6.5,
any Transferring Shareholder has transferred Shares to an Affiliate of such
Transferring Shareholder, then prior to permitting such Affiliate to cease being
an Affiliate, the Transferring Shareholder shall cause such Affiliate to
transfer the Shares to such Transferring Shareholder or to another Affiliate of
such Transferring Shareholder.

         Section 6.6 Expenses. Each Shareholder transferring any Shares pursuant
to this Article VI shall bear its own expenses incurred in connection with such
transaction.

         Section 6.7 Further Assurances. Each of the Shareholders shall do, and
shall cause Interativa to do, all things necessary to consummate the
transactions contemplated by this Article VI as promptly as practicable,
including, without limitation, entering into agreements and instruments with
third parties, obtaining governmental approvals and providing, subject to
Article VIII, information concerning the Companies.

         Section 6.8 Closing of Any Transfer. The closing of any transfer of

                 evidenced by this certificate, or any interest in the Shares,
                 is restricted by the terms of the Shareholders Agreement dated

                 pledge, mortgage, hypothecation, encumbrance or other
                 disposition shall be effective unless and until the terms and
                 conditions of such Shareholders Agreement shall have been
                 complied with in full."

                                  ARTICLE VII.

                                  ARTICLE VIII.
                                 CONFIDENTIALITY

         Section 8.1 General.

                  (a) Confidentiality Obligation. In the event Confidential
Information is disclosed to any Shareholder or any Affiliate or Representative
of such Shareholder, each such Shareholder or Affiliate or Representative shall
exercise at least the same degree of care in preventing the disclosure of such
Confidential Information to any third party, other than any other Affiliate or
Representative of such Shareholder, as such Shareholder or Affiliate or
Representative exercises in maintaining the confidentiality of its own
confidential proprietary information; provided, however, that such Shareholder
or Affiliate or Representative shall limit disclosure of such Confidential
Information to only the Shareholder or those Affiliates and Representatives of
such Shareholder who have a need to know the same in connection with
implementing, monitoring or otherwise carrying out the operation or management
of the Companies, or advising the Shareholder in connection therewith, and who
have been advised of and agree to comply with the restrictions upon such
Confidential Information set forth in this Agreement and may disclose such
Confidential Information (i) in connection with a proposed transfer of Shares
provided that any potential transferee executes a confidentiality agreement
containing the restrictions set forth in this Article VIII, (ii) in connection
with any disclosure necessary to comply with U.S., Canadian or other applicable
tax reporting requirements or (iii) as required to comply with applicable law or
applicable exchange rules. The restrictions set forth in this Section 8.1(a)
shall remain in effect until two (2) years after the date on which this
Agreement terminates pursuant to Article IX, or such earlier date as may be
provided in this Agreement.

                  (b) Definition of Confidential Information. For purposes of
this Agreement, "Confidential Information" shall mean (i) any technical
information that is proprietary to any Company, any Shareholder or any of their
respective Affiliates and disclosed in writing and marked "Confidential" in
connection with the implementation or carrying out of the operation and
management of the Companies and/or (ii) any financial, tax-related or commercial
information of any Company, any Shareholder or any of their respective
Affiliates that is disclosed during the term of this Agreement, provided that
Confidential Information shall not include any information so disclosed if:

                           (i) the recipient of such information shall have had
knowledge of such information prior to the date on which such recipient received
it from any Company, any Shareholder or any of their respective Affiliates;

                           (ii) such information shall have entered the public
domain through no fault of such recipient; or

                           (iii) such recipient shall have learned of such
information from a third party in such a manner that such recipient reasonably
believed that such third party was authorized to disclose such information.


                                       27
<PAGE>   31

         Section 8.2 Disclosure Required by Law or Court Order. If any recipient
of Confidential Information (including any Affiliate or Representative of a
Shareholder permitted to receive such information pursuant to Section 8.1(a)) is
required by order of any competent authority to disclose any Confidential
Information supplied to it by any other Person, the recipient required to make
such disclosure shall promptly notify the other Person or Persons involved so
that such Person or Persons may seek an appropriate protective order and/or
waive the required recipient's compliance with Section 8.1(a). If such
protective order or other remedy is not obtained, then the recipient or
recipients so required to disclose Confidential Information will furnish only
that portion of such Confidential Information that, in its reasonable judgment,
is legally required.

         Section 8.3 Use of Confidential Information. During the term of this
Agreement, any Confidential Information disclosed to a Person permitted to
receive such information pursuant to Section 8.1(a) (or any Affiliate or
Representative of such Person permitted to receive such information pursuant to
such Section) may be used by such recipient only in connection with
implementing, monitoring or otherwise carrying out the operation or management
of any Company and in connection with the resolution of any dispute between the
Parties. Each Shareholder and its Affiliates shall be permitted to provide
potential investors and lenders with Confidential Information so long as such
investors and lenders execute appropriate confidentiality agreements. Nothing in
this Agreement shall be construed to grant any additional rights in or licenses
to such Confidential Information. Upon the termination of this Agreement, each
Company and each Party (and its Affiliates) shall have the right to use its own
Confidential Information and shall not have the right to use another Party's or
Person's Confidential Information. The rights and obligations of the
Shareholders under this Section 8.3 shall survive the termination of this
Agreement.

                                   ARTICLE IX.
                            TERMINATION; LIQUIDATION

         Section 9.1 Term of Agreement. If not terminated earlier pursuant to
Sections 9.2 or 9.3, this Agreement shall terminate on the earlier to occur of
(i) the date there is only a single Shareholder of the Shares or (ii) the
fiftieth anniversary of the date hereof; provided that any claim for breach of
this Agreement that is the subject of arbitration pursuant to Section 10.2
hereof shall survive the termination of this Agreement. Notwithstanding anything
to the contrary herein, the provisions set forth in Sections 3.1 and 3.2,
Sections 4.1 and 4.2, Sections 6.6, 6.7 and 6.9, Article VIII, Article IX,
Article X and Article XI shall continue after the termination of this Agreement
in accordance with the terms set forth therein or until the expiration of the
statute of limitations (if not so specified) unless the Parties otherwise agree.

         Section 9.2 Termination by Unanimous Consent. This Agreement may be
terminated at any time by the written consent of all of the Parties hereto.

         Section 9.3 Termination on Bankruptcy or Liquidation. This Agreement
shall automatically terminate on the voluntary or involuntary bankruptcy or
dissolution of Interativa unless one or more of the remaining Shareholders who
holds at least a majority of the Shares votes to continue the existence of
Interativa.

         Section 9.4 Liquidation. In the event that this Agreement is terminated
pursuant to Sections 9.1, 9.2 or 9.3 and the Board and the Shareholders
determine to liquidate Interativa in accordance with the constituent documents
of Interativa, the Shareholders shall take such actions as are necessary to
dissolve and liquidate Interativa in accordance with applicable law and the
following requirements:

                  (a) Third Party Liquidator. The Board shall appoint a
third-party liquidator reasonably acceptable to the Shareholders who shall use
reasonable commercial efforts to sell or otherwise liquidate, or make a
custodian arrangement for, the assets of Interativa, either as going concerns or
as separate items; provided, however, that, subject to applicable law, each
Shareholder may bid for and purchase the assets of Interativa to be sold or
disposed of by the Board or such third-party liquidator. The Board or such
third-party liquidator shall seek to maximize the proceeds received for such
assets and shall use all reasonable efforts to obtain the best prices for such
assets. The Shareholders shall be bound by the terms of any sale or disposition
effected by the Board or any such third-party liquidator;

                  (b) Distribution of Proceeds. Subject to applicable law, after
the payment of all amounts owed by Interativa to any Person and the
establishment of such cash reserves as the Board or such third-party liquidator
determines to be reasonably necessary to fund any contingent or foreseeable
liability or obligation of any of the Companies, the Board or such third-party
liquidator shall distribute the proceeds of liquidation in the following order:
(A) first, to the payment of creditors of Interativa, (B) second, to the payment
of the Board's or such third-party liquidator's reasonable expenses in
liquidating Interativa; and (C) third, pro rata to the Shareholders in
proportion to their respective Ownership Percentages; and

                  (c) Continuing Liabilities. Each Shareholder shall remain
liable with respect to any commitment or obligation incurred by it prior to such
termination in connection with this Agreement or any other agreement related to
the business of Interativa (unless otherwise expressly specified therein),
including any breach of this Agreement.

                                   ARTICLE X.
                           GOVERNING LAW; ARBITRATION

         Section 10.1 Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, U.S.A., WITHOUT REGARD TO
ITS PRINCIPLES REGARDING CONFLICT OF LAWS (OTHER THAN SECTION 5-1401 OF THE
GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK).

         Section 10.2 Arbitration.

                  (a) Nature of the Dispute. Any dispute arising out of or
relating to this Agreement, including, without limitation, the interpretation of
any provision of this Agreement or the breach, termination or invalidity of this
Agreement (a "Dispute") shall be settled exclusively and finally by arbitration
if not otherwise settled pursuant to Section


                                       29
<PAGE>   33

10.2(b). It is specifically understood and agreed that any Dispute may be
submitted to arbitration irrespective of the magnitude thereof, the amount in
controversy or whether such Dispute would otherwise be considered justifiable or
ripe for resolution by a court.

                  (b) Dispute Procedure. In the event a Dispute arises between
the Parties regarding the application or interpretation of any provisions of
this Agreement, the aggrieved Party shall promptly notify the other Party of the
Dispute in writing. If the Parties shall have failed to resolve the Dispute
within thirty (30) days after delivery of such written notice, each of the
Parties shall nominate a senior officer of its management to meet at a mutually
agreed upon location, to resolve the Dispute. Should the Parties be unable to
resolve the Dispute to their mutual satisfaction within thirty (30) days after
such nomination, each Party shall have the right to pursue the resolution of
such Dispute in accordance with the provisions set forth below.

                  (c) Arbitration Procedure. The Parties agree to settle all
Disputes by arbitration in accordance with the Rules of Conciliation and
Arbitration of the International Chamber of Commerce in effect at the time of
the arbitration, excluding any such rules relating to the posting of security
for costs (the "Rules"), except as the Rules may be modified by this Agreement.

                           (i) A Party desiring to submit a Dispute to
arbitration hereunder shall file a demand for arbitration with the International
Chamber of Commerce (the "ICC") at its office in New York, New York (a
"Demand"). A copy of the Demand shall be sent to all other Parties at the same
time. The arbitration proceeding shall be conducted by a panel of three
arbitrators. Within ten (10) days after a Demand has been made by a Party, each
Party shall appoint one arbitrator. Within twenty (20) days after the Demand has
been made, the two arbitrators shall choose a third arbitrator who shall act as
chairperson of the arbitral proceedings. If the two arbitrators chosen by the
Parties do not agree upon a third arbitrator within twenty (20) days after the
filing of the Demand, then upon the application of any Party thereto, the third
arbitrator shall be appointed by the ICC.

                           (ii) Following the appointment of the arbitrators,
each of the Parties shall have the right to mail to the other Party (with a copy
to the arbitrators) a written request for the production of certain identified
documents or of all documents in possession of the other Parties relevant to any
claims or counterclaims in the arbitration. Within ten (10) days of receipt of
any such request, the receiving Parties may make written objection to the
requesting Party (with a copy to the arbitrators) to all or part of such
request, on the ground that it is unduly burdensome, that the documents
requested are irrelevant or privileged, or that such documents are equally
available to the requesting Party. The arbitrators shall rule on the validity of
any such objections and the parties shall produce documents in accordance with
such order. The documents requested shall be delivered within fifteen (15) days
of receipt of such request, unless the arbitrators otherwise direct.

                           (iii) The site of the Dispute resolution shall be in
the city of New York, New York, U.S.A. The Parties shall diligently and
expeditiously proceed with arbitration. Upon the conclusion of any hearing, the
Parties shall have thirty (30) days to


                                       30
<PAGE>   34

submit written briefs in support of their respective positions. The arbitrators
shall be instructed to render a written decision within thirty (30) days after
the filing of such briefs, subject to any reasonable delay due to unforeseen
circumstances.

                           (iv) Except to the extent the Parties' remedies may
be limited by the terms of this Agreement, the arbitrators shall be empowered to
award any remedy available under the laws of New York, including monetary
damages (but excluding any punitive, consequential, special or incidental
damages). The award of the arbitrators shall be in writing with reasons for such
award and signed by the arbitrators.

                           (v) To the extent possible, the arbitrators in the
arbitration proceeding provided for herein should be individuals experienced in
the internet, investment and finance industries and competent to pass on the
matters presented for arbitration, but such arbitrators shall have no interest
in or prior connection with any of the Parties, and shall be impartial toward
each Party at the time of their selection.

                           (vi) The parties to the arbitration shall share
equally the compensation and expenses of the arbitrators as well as all fees
imposed by the ICC including, but not limited to, transcripts, hearing room
rentals, filing fees, and administrative costs. The prevailing party shall be
entitled to recover from the other party its costs, expenses and reasonable
legal fees.

                           (vii) Each of the Parties recognizes and affirms that
in the event of breach by any of them of any of the provisions of this
Agreement, money damages alone may be inadequate and an adequate remedy at law
may not exist. Accordingly, each of the Parties agrees that any Party shall have
the right, in addition to any other rights and remedies existing in its favor,
to enforce its rights and the obligations of any other Party under this
Agreement not only by an action or actions for damages, but also by an action or
actions for specific performance, injunction and/or other equitable relief in
order to enforce or prevent any violations of the provisions of this Agreement.
In accordance with the foregoing, each Party hereby waives any claim or defense
that the other Party has or may have an adequate remedy at law.

                  (d) Binding Decision and Award. Any decision or award of the
arbitral tribunal shall be final and binding upon the parties to the arbitration
proceeding. The Parties hereby waive to the extent permitted by law any rights
to appeal or to review of such award by any court or tribunal. The Parties agree
that the arbitral award may be enforced against the parties to the arbitration
proceeding or their assets wherever they may be found and that a judgment upon
the arbitral award may be entered in any court having jurisdiction thereof.

                  (e) Waiver of Immunity. To the extent that each Party has or
hereinafter may acquire any immunity from jurisdiction of any court or from any
legal process (whether through service of notice, attachment prior to judgment,
attachment in aid of execution, execution or otherwise) with respect to itself
or is property, it hereby irrevocably waives such immunity in respect of its
obligations under this Agreement.


                                       31
<PAGE>   35

         Section 10.3 Waiver of Jury Trial. Each Party hereby irrevocably waives
all right to trial by jury in any action, proceeding or counterclaim arising out
of or relating to this Agreement.

except as otherwise may be provided in any other written agreement between or
among one or more of the Shareholders and Interativa and in no event shall any
Shareholder owe any fiduciary duty or similar duty to the other Shareholder in
its capacity as a shareholder of Interativa. No Shareholder shall act as an
agent for or on behalf of Interativa, except as specifically is provided in any
other written agreement between Interativa and such Shareholder. Each

avoid the appearance or creation of any other or greater relationship between
the Shareholders and Interativa.

                  (b) Contracts Outside the Scope of this Agreement. Any

entering into such agreement shall be subject to any liability which might arise

                  (a) Each Shareholder represents and warrants to the other
Shareholder that all negotiations relating to this Agreement and the
transactions contemplated hereby have been carried on without the intervention
of any Person acting on behalf of any Shareholders in such manner as to give
rise to a valid claim against Interativa or any Shareholders for any broker's or
finder's fee or similar compensation in connection with the transactions
contemplated by this Agreement.

                  (b) Each Shareholder (the "Indemnitor") hereby agrees to
indemnify and hold harmless the other Shareholder from any Loss that such other
Shareholder incurs as a result of or arising out of any claim by any Person for
any broker's or finder's fees or

similar compensation demands made by such Person against the Indemnitor in
connection with the transactions contemplated by this Agreement.

         Section 11.16 News Releases. Each Shareholder agrees to use its
reasonable efforts to ensure that no public release or announcement concerning
the operation of Interativa and the transactions contemplated by this Agreement
shall be issued by such Shareholder without providing the other Shareholder with
an opportunity to comment. Each Shareholder shall exercise reasonable care in
not disseminating any information relating to Interativa to the news media
without the prior consent of the other Shareholder.

         Section 11.17 Compliance with Transaction Documents. The Shareholders
shall comply and shall cause their Affiliates to comply with the provisions of
each of the Transaction Documents to which they are a party. No transfer of any
interest in Interativa by any Shareholder shall relieve such Shareholder of its
obligations under any of the Transaction Documents to which it is a party unless
expressly agreed to by the other parties to such Transaction Documents.

number of counterparts each of which shall be deemed an original but all of
which together shall constitute one and the same instrument. This Agreement
shall become effective when such counterparts have been executed by and
delivered to each Party. Delivery by facsimile of an executed counterpart of
this Agreement shall be deemed to be delivery of an original counterpart of this
Agreement.
