transfer or exchange, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.

          Prior to due presentment of this Security for registration of

which there is an Issuing Person, such Issuing Person) does not set a record
date for payment of a dividend on the Common Stock (or, if any Adjustment
Event has occurred in which there is an Issuing Person, the common stock of
such Issuing Person) in respect of any quarterly period at least five Business
Days prior to a Regular Record Date, the Company shall have the option to
defer the coupon payment immediately following such Regular Record Date until
the Maturity Date. Upon the Maturity Date, the Company may elect to cancel
such deferred coupons. Any coupons which have been so deferred shall not
accrue further coupons thereon. In the event of any such deferral or
cancellation, the Company shall give notice thereof to the Trustee and each
Holder of the Notes at least 3 Business Days prior to the relevant coupon
payment date.

          Section 2.02 Mandatory Exchange.

          On the Maturity Date, each $25 principal amount of the Notes shall
be mandatorily exchanged for a number of shares of Common Stock (and/or, if a
Significant Spin-off, a Significant Cash Distribution or an Adjustment Event
has occurred, securities, cash and/or other property, as applicable) equal to
the Total Exchange Shares; provided, however, that, pursuant to Section 2.04,
no fractional shares of Common Stock shall be issued. The Holders of the Notes
shall be responsible for the payment of any and all brokerage costs upon the
subsequent sale of such shares.

                                     -6-
<PAGE>

          In lieu of delivering some or all of the Total Exchange Shares, the
Company may, at the Company's election, pay to the Holder surrendering such
Notes an amount in cash equal to the number of Total Exchange Shares subject
to such election multiplied by the average Closing Price of such securities
over the 20 Trading Day period referred to in the definition of Daily Amount.
To exercise this election, the Company shall notify the Trustee and each
Holder of the Notes of its election on or before the beginning of such 20
Trading Day period, and if the Company is electing to pay cash instead of
delivering a portion of the Total Exchange Shares the Company is otherwise
required to deliver, the Company shall specify the portion of the Total
Exchange Shares in respect of which the Company will deliver cash.

          Section 2.03 Procedure for Exchange.

          In order to receive the shares of Common Stock (and/or, if a
Significant Spin-off, a Significant Cash Distribution or an Adjustment Event
has occurred, securities, cash and/or other property, as applicable) pursuant
to Section 2.02, the Holder of any Note must surrender such Note to the
Company (or its agent appointed for such purpose), at its office maintained
for such purpose in New York, New York. Delivery of the certificates and of
any check for any cash may be delayed for a reasonable period of time at the
request of the Company in order to effectuate the calculation of the
adjustments under Article III, to obtain any certificate representing
securities to be delivered, or to complete any reapportionment of securities
to be delivered which is required by the Indenture or this Note or to comply
with any applicable law.

          Section 2.04 No Fractional Shares.

          If more than one Note shall be surrendered for exchange pursuant to
Section 2.03 at one time by the same holder, the number of full shares of
Common Stock or other securities which shall be delivered upon such exchange,
in whole or in part, as the case may be, shall be computed on the basis of the
aggregate number of Notes surrendered. No fractional shares or scrip
representing fractional shares of Common Stock or other securities shall be
issued or delivered pursuant to Section 2.02. In lieu of any fractional shares
of Common Stock or other securities which, but for the immediately preceding
sentence, would otherwise be deliverable pursuant to Section 2.02, the Company
shall pay cash for such fractional share of security equal to the applicable
fraction of the Closing Price of such share or security on the Trading Day
immediately preceding the Maturity Date.

          Section 2.05 Taxes.

          The Company will pay any and all documentary, stamp, transfer or
similar taxes that may be payable in respect of the transfer and delivery of
Common Stock (and/or, if a Significant Spin-off, a Significant Cash
Distribution or an Adjustment Event has occurred, securities, cash and/or
other property, as applicable) pursuant hereto; provided, however, that the
Company shall not be required to pay any such tax which may be payable in
respect of any transfer involved in the delivery of Common Stock (and/or, if a
Significant Spin-off, a Significant Cash Distribution or an Adjustment Event
has occurred, securities, cash and/or other property, as applicable) in a name
other than that in which the Notes so exchanged were registered, and no such
transfer or delivery shall be made unless and until the person requesting

                                     -7-
<PAGE>

such transfer has paid to the Company the amount of any such tax, or has
established, to the satisfaction of the Company, that such tax has been paid.

          The Company shall not be obligated to pay any additional amount on
the Notes in respect of taxes, except as otherwise provided in this Section
2.05 and in Section 4.01 hereof.

          Section 2.06 Delivery of Securities upon Maturity.

          All shares of Common Stock deliverable to Holders upon exchange of
the Notes shall be delivered to such Holders, whenever practicable, in such
manner (such as by book-entry transfer) so as to assure same-day transfer of
such shares to Holders and otherwise in the manner customary at such time for
delivery of such shares and shares of the same type.

          Section 2.07 Insolvency.

          In the event an Insolvency Event occurs prior to or on the Maturity
Date, all of the Company's obligations under the Notes shall immediately and
automatically terminate, without the necessity of any notice, payment or
action by the Company or the Trustee. Following such termination, the Holders
of the Note shall not receive any further coupon payments and no principal
payments, shares of Common Stock, cash in lieu of such shares or any other
property shall be delivered to the Holders of the Notes.

          Section 2.08 Calculations.

          The Company shall be responsible for the calculation in good faith
of any amounts pursuant hereto (other than the amount of coupons, for which
the Trustee shall be the calculation agent), including, but not limited to,
the determination of the Closing Prices of the Common Stock, the calculation
of the Daily Amounts and the calculation of any adjustments required to be
made pursuant to Article III. All calculations made by the Company, absent
manifest error, shall be final and binding upon the Holders of the Notes. The
Company shall provide a schedule of such calculations to the Trustee, and the
Trustee shall be entitled to rely conclusively on the accuracy of such
calculations without independent verification.

          Section 2.09 Modification.

          In addition to the matters set forth in Section 9.02 of the
Indenture, no supplemental indenture to the Indenture shall, without the
consent of each Holder of each Outstanding Note affected thereby, change the
manner in which the Total Exchange Shares is determined.

                                 ARTICLE III.

                 ADJUSTMENT OF DAILY AMOUNT AND CLOSING PRICE

          Section 3.01 Adjustments for Dividends, Distributions, Stock
                       Splits, Etc.

          (a) Stock Dividends. If the Seller shall, after the Issue Date, pay
or make a dividend or other distribution on Common Stock in Common Stock, the
Share Component in

                                     -8-
<PAGE>

effect at the close of business on the date fixed for the determination of
holders of Common Stock entitled to receive such dividend or distribution
shall be increased by multiplying such Share Component by a fraction of which:

          (i) the numerator shall be the sum of the number of shares of Common
     Stock outstanding at the close of business on the date fixed for such
     determination and the total number of shares constituting such dividend
     or other distribution; and

          (ii) the denominator shall be the number of shares of Common Stock
     outstanding at the close of business on the date fixed for such
     determination,

such increase to become effective immediately at the opening of business on
the day following the date fixed for such determination. For the purposes of
this Section 3.01(a), the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Seller but
shall include any shares issuable in respect of any scrip certificates issued
in lieu of fractions of shares of Common Stock.

          (b) Rights, Warrants or Options. If the Seller shall, after the
Issue Date, issue rights, warrants or options, other than pursuant to any
dividend reinvestment plans, to all holders of Common Stock entitling such
holders, for a period expiring within 45 days after the record date for the
determination of holders of Common Stock entitled to receive such rights,
warrants or options, to subscribe for or purchase shares of Common Stock at an
offering price per share less than the Current Market Price of the Common
Stock on the date of announcement of such issuance, the Share Component in
effect at the close of business on the date of such announcement shall be
increased by multiplying such Share Component by the following fraction of
which:

          (i) the numerator shall be the number of shares of Common Stock
     outstanding at the close of business on the date of such announcement
     plus the total number of shares of Common Stock so offered for
     subscription or purchase; and

          (ii) the denominator shall be the number of shares of Common Stock
     outstanding at the close of business on the date of such announcement
     plus the total number of shares of Common Stock that the aggregate of the
     offering price of the total number of shares of Common Stock so offered
     for subscription or purchase would purchase at such Current Market Price,

such increase to become effective immediately after the opening of business on
the Business Day following the date of such announcement. To the extent that
shares of Common Stock are not delivered pursuant to such rights, warrants or
options, the Share Component shall be readjusted to be the Share Component
that would then be in effect had the adjustments made upon the issuance of
such rights, warrants and options been made on the basis of delivery of only
the number of shares of Common Stock actually delivered. For the purposes of
this Section 3.01(b), the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Seller but
shall include any shares issuable in respect of any scrip certificates issued
in lieu of fractions of shares of Common Stock.

                                     -9-
<PAGE>

          (c) Stock Subdivisions, Splits or Combinations. If outstanding
shares of Common Stock shall be subdivided or split, after the Issue Date,
into a greater number of shares of Common Stock, the Share Component in effect
at the close of business on the day preceding the day upon which such
subdivision or split becomes effective shall be proportionately increased, and
conversely, in case outstanding shares of Common Stock shall be combined,
after the Issue Date, into a smaller number of shares of Common Stock, the
Share Component in effect at the close of business on the day preceding the
day upon which such combination becomes effective shall be proportionately
reduced, such increase or reduction, as the case may be, to become effective
immediately at the opening of business on the day following the day upon which
such subdivision, split or combination becomes effective.

          (d) Distribution of Indebtedness or Assets. If the Seller shall,
after the Issue Date, by dividend or otherwise, distribute to all holders of
Common Stock evidences of its indebtedness or assets (including shares of
capital stock, securities, cash and property, but excluding any rights,
warrants or options referred to in Section 3.01(b), any dividend or
distribution paid exclusively in cash and any dividend or distribution
referred to in Section 3.01(a) or in connection with the liquidation,
dissolution or winding up of the Seller), the Share Component in effect at the
close of business on the date fixed for the determination of holders of Common
Stock entitled to receive such distribution shall be adjusted by multiplying
such Share Component by a fraction of which:

          (i) the numerator shall be the Current Market Price of the Common
     Stock on the date fixed for such determination; and

          (ii) the denominator shall be such Current Market Price of the
     Common Stock less the then Fair Market Value of the portion of the assets
     or evidences of indebtedness so distributed applicable to one share of
     Common Stock,

such adjustment to become effective at the opening of business on the day
following the date fixed for such determination of holders of Common Stock
entitled to receive such distribution; provided, however, that in the event
the Fair Market Value of the portion of any capital stock or other equity
securities so distributed applicable to one share of Common Stock is equal to
or greater than 40% of the Current Market Price of the Common Stock on such
determination date (such distribution, a "Significant Spin-Off"), in lieu of
the foregoing adjustment, (x) for the purpose of calculating the number of
Contract Shares receivable by the Holders of the Notes with respect to each
Calculation Date, the references to "Closing Price" in the definition of Daily
Amount shall mean the Closing Price plus the Fair Market Value of such capital
stock or other equity securities so distributed per share of Common Stock and
(y) in addition to the Company delivering the shares of Common Stock to be
delivered hereunder, the Company shall make adequate provisions to provide for
the delivery on the Maturity Date the number of shares of such capital stock
or other equity securities the Holders of the Notes would have received had
the Holders of the Notes held on the determination date for the Significant
Spin-Off the number of shares of Common Stock required to be delivered
hereunder as determined in accordance with clause (x) above. In any case in
which this Section 3.01(d) is applicable, Section 3.01(b) shall not be
applicable. In the event that such dividend or distribution is not so paid or
made, each Share Component shall again be adjusted to be the Share Component
that would then be in effect

                                     -10-
<PAGE>

if such dividend or distribution had not been declared (and no such adequate
provision described in the proviso above shall be made).

          (e) Cash Distributions. In case the Seller shall, after the Issue
Date, distribute cash to all holders of Common Stock, excluding (A) any
dividend or distribution in connection with the liquidation, dissolution or
winding up of the Seller or (B) any quarterly cash dividend on the Common
Stock to the extent that the cash dividend per share of Common Stock does not
exceed $0.31 per share, as adjusted to reflect stock splits, subdivisions or
combinations of the Common Stock after the Issue Date, then the Share
Component in effect at the close of business on such record date shall be
adjusted by multiplying such Share Component by a fraction of which:

          (i) the numerator shall be the Current Market Price of the Common
     Stock on such record date; and

          (ii) the denominator shall be such Current Market Price of the
     Common Stock less the amount of cash so distributed (in excess of the
     amount excluded as provided above) applicable to one share of Common
     Stock,

such adjustment to become effective at the opening of business on the day
following such record date; provided, however, that in the event the portion
of cash so distributed applicable to one share of Common Stock is greater than
25% (but less than 75%) of the Current Market Price of the Common Stock on
such record date, in lieu of the foregoing adjustment, (x) for the purpose of
calculating the number of Contract Shares receivable by the Holders of the
Notes with respect to each Calculation Date, the references to "Closing Price"
in the definition of Daily Amount shall mean the Closing Price plus the amount
of cash so distributed per share of Common Stock and (y) in addition to the
Company delivering the shares of Common Stock to be delivered hereunder, the
Company shall make adequate provisions to provide for the delivery on the
Maturity Date the amount of cash the Holders of the Notes would have received
had the Holders of the Notes held on the record date for such distribution the
number of shares of Common Stock required to be delivered hereunder as
determined in accordance with clause (x) above; provided, further, that in the
event the portion of cash so distributed applicable to one share of Common
Stock is equal to or greater than 75% of the Current Market Price of the
Common Stock on such record date, in lieu of the foregoing adjustment, such
distribution will be treated as an Adjustment Event under Section 3.02 (a cash
distribution referred to in either of the two preceding provisos, a
"Significant Cash Distribution"). If such dividend or distribution is not so
paid or made, each Share Component shall again be adjusted to be the Share
Component that would then be in effect if such dividend or distribution had
not been declared (and no such adequate provision or adjustment under Section
3.02 shall be made).

          (f) Tender or Exchange Offer. If, after the Issue Date, the Seller
or any Subsidiary of the Seller shall make a tender or exchange offer (other
than any odd-lot tender offer) for all or any portion of the Common Stock and
upon expiration of such tender or exchange offer (as amended upon the
expiration thereof) the Seller or its Subsidiary shall be required to pay to
holders of Common Stock based on the acceptance (up to any maximum specified
in the terms of the tender or exchange offer) of Purchased Shares any
consideration, then if the cash and Fair Market Value of the aggregate
consideration per share of Common

                                     -11-
<PAGE>

Stock to be paid in such tender or exchange offer exceeds the Current Market
Price of the Common Stock as of the last time (the "Expiration Time") tenders
could have been made pursuant to such tender or exchange offer (as it may be
amended), then, the Share Component in effect at the close of business on the
day of the Expiration Time shall be adjusted by multiplying such Share
Component by a fraction of which:

          (i) the numerator shall be equal to the product of (A) the Current
     Market Price of the Common Stock as of the Expiration Time and (B) the
     number of shares of Common Stock outstanding (including any tendered
     shares) at the close of business on the date of the Expiration Time less
     the number of all shares validly tendered and not withdrawn as of the
     Expiration Time (the shares deemed so accepted, up to any such maximum,
     being referred to as the "Purchased Shares"); and

          (ii) the denominator shall be equal to (A) the product of (x) the
     Current Market Price of the Common Stock as of the Expiration Time and
     (y) the number of shares of Common Stock outstanding (including any
     tendered shares) at the close of business on the date of the Expiration
     Time less (B) the amount of cash plus the Fair Market Value of the
     aggregate consideration payable to holders of Common Stock in such tender
     or exchange offer (assuming the acceptance, up to any maximum specified
     in the terms of the tender or exchange offer, of Purchased Shares),

such adjustment to become effective at the opening of business on the date
following the date of the Expiration Time.

          (g) Reclassification of Common Stock. If the Seller, after the Issue
Date, reclassifies the Common Stock into securities, including securities
other than Common Stock (other than any reclassification upon an Adjustment
Event to which Section 3.02 applies), such reclassification shall be deemed to
involve:

          (i) to the extent such securities are securities other than Common
     Stock, a distribution of such securities to all holders of Common Stock
     under Section 3.01(d) (and the effective date of such reclassification
     shall be deemed to be "the date fixed for the determination of holders of
     Common Stock entitled to receive such distribution" and the "date fixed
     for such determination" within the meaning of Section 3.01(d)); and

          (ii) to the extent such securities are Common Stock, a subdivision,
     split or combination, as the case may be, of the number of shares of
     Common Stock outstanding immediately prior to such reclassification into
     the number of shares of Common Stock outstanding immediately thereafter
     under Section 3.01(c) (and the effective date of such reclassification
     shall be deemed to be "the day upon which such subdivision or split
     becomes effective" or "the day upon which such combination becomes
     effective", as the case may be, and "the day upon which such subdivision,
     split or combination becomes effective" within the meaning of Section
     3.01(c)).

          (h) Rounding. All adjustments to the Share Component shall be
calculated to the nearest 0.0001 of a share of Common Stock (or if there is
not a nearest 0.0001 of a share, to the next lower 0.0001 of a share). No
adjustment in the Share Component shall be required unless

                                     -12-
<PAGE>

such adjustment would require an increase or decrease of at least one percent
thereof; provided, however, that any adjustments that by reason of this
Section 3.01(h) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment.

          (i) Corresponding Adjustments to Closing Price. If any adjustment is
made to the Share Component pursuant to paragraphs (a)-(g) of this Section
3.01 (other than paragraphs (d) and (e) of this Section 3.01 as they relate to
any Significant Spin-Off and Significant Cash Distribution, respectively,
except as expressly provided therein), an adjustment will also be made to the
Closing Price as such term is used throughout the definition of Daily Amount
(so as to maintain the intended proportional relationship between the Closing
Price and Initial Price and Threshold Appreciation Price) to determine which
of the three clauses in the definition of Daily Amount will be applicable on
the relevant Trading Day and in the calculation required to be made pursuant
to clause (ii) of the definition of Daily Amount. The required adjustment to
the Closing Price will be made on each day for which a Daily Amount is
calculated by multiplying the Closing Price by the same factor by which the
Share Component was adjusted pursuant to the procedures described above in
paragraphs (a)-(g).

          (j) Rights Agreement. Each share of Common Stock issued pursuant
hereto shall be entitled to receive the appropriate number of Rights, if any,
and the certificates representing such shares shall bear such legends, if any,
in each case as provided by and subject to the terms of the Rights Agreement
as in effect on the date of such issuance. Rights or warrants (including the
Rights) distributed by the Seller to all holders of its Common Stock entitling
them to subscribe for or purchase shares of the Seller's capital stock (either
initially or under certain circumstances), which rights or warrants, until the
occurrence of a specified event or events ("Trigger Event"), (i) are deemed to
be transferred with such shares of Common Stock, (ii) are not exercisable and
(iii) are also issued in respect of future issuances of shares of Common Stock
shall be deemed not to have been distributed for purposes of Section 3.01 (and
no adjustment to the Share Component under Section 3.01 will be required)
until the occurrence of the earliest Trigger Event. Upon the occurrence of a
Trigger Event, such rights or warrants shall be deemed to have been
distributed for purposes of Section 3.01 (and an adjustment under Section 3.01
shall be required). If such right or warrant is subject to subsequent events,
upon the occurrence of which such right or warrant shall become exercisable to
purchase different distributed assets, evidences of indebtedness or other
assets, or entitle the holder to purchase a different number or amount of the
foregoing or to purchase any of the foregoing at a different purchase price,
then the occurrence of each such event shall be deemed to be the date of
issuance and record date with respect to a new right or warrant (and a
termination or expiration of the existing right or warrant without exercise by
the holder thereof). In addition, in the event of any distribution (or deemed
distribution) of rights or warrants, or any Trigger Event or other event (of
the type described in the preceding sentence) with respect thereto, that
resulted in an adjustment to the Share Component under Section 3.01:

          (x) in the case of any such rights or warrants that shall all have
     been redeemed or repurchased without exercise by any holders thereof, the
     Share Component shall be readjusted upon such final redemption or
     repurchase to give effect to such distribution or Trigger Event, as the
     case may be, as though it were a cash distribution, equal to the per
     share redemption or repurchase price received by a holder of shares of
     Common Stock with respect to such rights or warrants (assuming such
     holder had retained such rights or

                                     -13-
<PAGE>

     warrants), made to all holders of shares of Common Stock as of the date
     of such redemption or repurchase; and

          (y) in the case of such rights or warrants that shall have expired
     or been terminated without exercise, the Share Component shall be
     readjusted as if such rights and warrants had never been issued.

          Section 3.02 Adjustment for Consolidation, Merger or Other
Adjustment Event. In the event of:

          (a) any consolidation or merger of the Seller with or into another
     Person (other than a merger or consolidation in which the Seller is the
     continuing or surviving corporation and in which the shares of Common
     Stock outstanding immediately prior to the merger or consolidation are
     not exchanged for cash, securities or other property of the Seller or
     another Person);

          (b) any sale, transfer, lease or conveyance to one or more Persons
     of all or substantially all of the property of the Seller (other than any
     such event that constitutes a Significant Spin-Off);

          (c) any statutory share exchange of the Seller with another Person;

          (d) any Significant Cash Distribution referred to in the second
     proviso of Section 3.01(e); or

          (e) any liquidation, dissolution or winding up of the Seller other
     than as a result of or after the occurrence of a Insolvency Event (any
     event described in clauses (a), (b), (c), (d) and (e), an "Adjustment
     Event");

the Daily Amount will be adjusted to provide that the Holders of the Notes
will receive pursuant hereto the kind and amount of securities, cash and other
property receivable upon, or in connection with, such Adjustment Event
(without any interest thereon and without any right to dividends or
distribution thereon that have a record date that is prior to the Maturity
Date) by a holder (including any shares of Common Stock retained by such
holder in connection with such Adjustment Event) of the number of Contract
Shares that would otherwise be issuable hereunder if the Calculation Dates had
occurred immediately prior to such Adjustment Event (and the Total Exchange
Shares were calculated based on the Daily Amounts for the 20 Trading Days
immediately prior to the effective date of the initial Adjustment Event),
assuming that such holder of Common Stock is not a Person with which the
Seller consolidated or into which the Seller merged or that merged into the
Seller or to which such sale or transfer was made, as the case may be (any
such Person, a "Constituent Person"), or an Affiliate of a Constituent Person
to the extent such Adjustment Event provides for different treatment of Common
Stock held by Affiliates of the Seller and non-affiliates and such holder of
Common Stock failed to exercise its rights of election, if any, as to the kind
or amount of securities, cash and other property receivable upon such
Adjustment Event (provided that if the kind or amount of the securities, cash
and other property receivable upon such Adjustment Event is not the same for
each share of Common Stock held immediately prior to such Adjustment Event by
other than a Constituent Person or an Affiliate thereof and in respect of
which such rights of election shall not have been

                                     -14-
<PAGE>

exercised ("non-electing share"), then for the purpose of this Section 3.02
the kind and amount of securities, cash and other property receivable upon
such Adjustment Event by each non-electing share shall be deemed to be the
kind and amount so receivable per share by a plurality of the non-electing
shares).

          If such an Adjustment Event occurs, the Company shall execute and
deliver an agreement supplemental hereto providing that the Holders of the
Notes shall have the rights provided by this Section 3.02. Such supplemental
agreement shall provide for adjustments that, for events subsequent to the
effective date of such supplemental agreement, shall be as nearly equivalent
as may be practicable to the adjustments provided for in this Article III. The
above provisions of this Article III shall similarly apply to successive
Adjustment Events.

          Section 3.03 Notice of Adjustments and Certain other Events.

          The Company shall, upon being notified of the occurrence of an event
that requires an adjustment to the Daily Amount or the occurrence of an
Adjustment Event (or, in either case, if the Company is not aware of such
occurrence, as soon as practicable after becoming so aware), promptly notify
the Trustee and each Holder of Notes in writing of the occurrence of such
event including a statement setting forth the factors by which the Closing
Price and the Share Component used in the calculation of the Daily Amount are
to be adjusted in order to determine which clause of the Daily Amount
definition will apply on each day on which a Daily Amount is required to be
calculated.

          Section 3.04 Tax Treatment. The Company intends to treat and, by
purchasing this Note, the Holder hereof agrees to treat, for all tax purposes,
this Note as a financial contract rather than as a debt instrument.

                  Section 3.01. Corporate Purpose; Powers of the Board. The
parties hereto confirm that it is their intention that the business and affairs
of the Company shall be managed by the Board which may exercise all the powers
of the Company. The Board shall have the power and authority to take all actions
that are not by Law, the Memorandum of Association, the Bye-Laws, or this

(the "Chairman"). The initial deputy chairman ("Deputy Chairman") of the Board
shall be Louis Tanguay. After the initial one-year term, each of the Chairman
and the Deputy Chairman shall be designated by the Shareholders at the annual
meeting of Shareholders on a rotating basis in the following order: BCI
Investments, SBCI Brazil Holding (in the event that SBCI Brazil Holding has the
right to nominate two (2) directors to the Board pursuant to Section
3.04(a)(iii) hereof) and AM Latin America.

Section 3.04(a)(ii) each of BCI Investments and AM Latin America shall be
entitled to nominate for election three (3) directors to the Board for so long
as BCI Investments or AM Latin America, as the case may be, holds at least 20%
of the Outstanding Shares of the Company; provided, however, that neither BCI
Investments nor AM Latin America may exercise such right at any time when it is
a Defaulting Shareholder. If at any time either BCI Investments or AM Latin
America shall hold less than 20% of the Outstanding Shares of the Company, BCI
Investments or AM Latin America, as the case may be, shall forfeit its right to
nominate for election three (3) directors to the Board pursuant to this Section
3.04(a)(i); provided, however, that, subject to Section 3.04(a)(ii), if: (A) at
any time subsequent to forfeiting such right, either BCI Investments or AM Latin
America, as the case may be, holds at least 20% of the Outstanding Shares of the
Company, and (B) BCI Investments or AM Latin America, as the case may be, has
not previously transferred its right to nominate for election three (3)
directors to the Board to a Veto Transferee pursuant to Section 3.13(a), then
the other Initial Shareholders shall vote their Shares in order to permit BCI
Investments or AM Latin America, as the case may be, to regain its right to
nominate for election three (3) directors to the Board pursuant to this Section
3.04(a)(i).

          (ii) At any time when SBCI Brazil Holding shall have the right to
     nominate for election one (1) director to the Board pursuant to Section
     3.04(b) hereof or two (2) directors to the Board pursuant to Section
     3.04(a)(iii) hereof, each of BCI Investments and AM Latin America shall be
     entitled to nominate for election two (2) directors to the Board for so
     long as it holds at least twenty percent (20%) of the Outstanding Shares of
     the Company; provided, however, that no such Shareholder may exercise such
     right at any time when it is a Defaulting Shareholder. If at any time
     either BCI Investments or AM Latin America shall hold less than twenty
     percent (20%) of the Outstanding Shares of the Company, BCI Investments or
     AM Latin America, as the case may be, shall forfeit its right to nominate
     for election two (2) directors to the Board pursuant to this Section
     3.04(a)(ii); provided, however, that if: (A) at any time subsequent to
     forfeiting such right, either BCI Investments or AM Latin America, as the
     case may be, holds at least 20% of the Outstanding Shares of the Company,
     (B) at such time SBCI Brazil Holding has the right to nominate for election
     one (1) director to the Board pursuant to Section 3.04(b) hereof or two (2)
     directors to the Board pursuant to Section 3.04(a)(iii) hereof, and (C) BCI
     Investments or AM Latin America, as the case may be, has not previously
     transferred its right to nominate for election two (2) directors to the
     Board to a Veto Transferee pursuant to Section 3.13(a), then the other
     Initial Shareholders shall vote their Shares in order to permit BCI
     Investments or AM Latin America, as the case may be, to regain its right to
     nominate for election (2) directors to the Board pursuant to this Section
     3.04(a)(ii).

          (iii) If at any time after the date hereof, SBCI Brazil Holding holds
     twenty percent (20%) or more of the Outstanding Shares of the Company (the
     date on which such interest is acquired, the "Two Director Date"), it shall
     be entitled to nominate for election two (2) directors to the Board for so
     long as it continues to hold at least twenty percent (20%) of the
     Outstanding Shares of the Company; provided that SBCI Brazil Holding may
     not exercise such right at any time when it is a Defaulting Shareholder. If
     at any time prior to the Two Director Date SBCI Brazil Holding shall hold
     less than ten percent (10%) of the Outstanding Shares of the Company, or if
     at any time after the Two Director Date SBCI Brazil Holding shall hold less
     than twenty percent (20%) of the Outstanding Shares of the Company, it
     shall forfeit its right to nominate for election two (2) directors to the
     Board pursuant to this Section 3.04(a)(iii); provided, however, that if:
     (A) at any time subsequent to forfeiting such right, SBCI Brazil Holding
     holds at least 20% of the Outstanding Shares of the Company, and (B) SBCI
     Brazil Holding has not previously transferred its right to nominate for
     election two (2) directors to the Board to a Veto Transferee pursuant to
     Section 3.13(a), then the other Initial Shareholders shall vote their
     Shares in order to permit SBCI Brazil Holding to regain its right to
     nominate for election two (2) directors to the Board pursuant to this
     Section 3.04(a)(iii).

<PAGE>

                  (b) Each of BCI Investments and AM Latin America shall be
entitled hereunder to nominate for election one (1) director to the Board for so
long as it holds at least ten percent (10%) of the Outstanding Shares of the
Company; provided that neither BCI Investments nor AM Latin America may exercise
such right at any time when it is a Defaulting Shareholder. If at any time such
Initial Shareholder shall hold less than ten percent (10%) of the Outstanding
Shares of the Company, it shall forfeit such right; provided, however, that if:
(i) at any time subsequent to forfeiting such right, either BCI Investments or
AM Latin America, as the case may be, holds at least 10% of the Outstanding
Shares of the Company, and (ii) BCI Investments or AM Latin America, as the case
may be, has not previously transferred its right to nominate for election one
(1) director to the Board to a Director Transferee pursuant to Section 3.13(b)
or its right to nominate for election two (2) or three (3) directors to the
Board to a Veto Transferee pursuant to Section 3.13(a), then the other Initial
Shareholders shall vote their Shares in order to permit BCI Investments or AM
Latin America, as the case may be, to regain its right to nominate for election
one (1) director to the Board pursuant to this Section 3.04(b). Subject to the
immediately succeeding sentence, if at any time after the date hereof, SBCI
Brazil Holding increases its ownership interest in the Company such that it
holds fifteen percent (15%) or more of the Outstanding Shares of the Company
(the date on which such interest is acquired, the "One Director Date"), SBCI
Brazil Holding shall be entitled to nominate for election one (1) director to
the Board for so long as it continues to hold at least ten percent (10%) of the
Outstanding Shares of the Company; provided that SBCI Brazil Holding may not
exercise such right at any time when it is a Defaulting Shareholder. If at any
time SBCI Brazil Holding shall hold less than ten percent (10%) of the
Outstanding Shares of the Company, it shall forfeit its right to nominate for
election one (1) director to the Board pursuant to this Section 3.04(b);
provided, however, that if: (i) at any time subsequent to forfeiting such right,
SBCI Brazil Holding holds at least 10% of the Outstanding Shares of the Company,
and (ii) SBCI Brazil Holding has not previously transferred its right to
nominate for election one (1) director to the Board to a Director Transferee
pursuant to Section 3.13(b) or its right to nominate for election two (2)
directors to the Board to a Veto Transferee pursuant to Section 3.13(a), then
the other Initial Shareholders shall vote their Shares in order to permit SBCI
Brazil Holding to regain its right to nominate for election (1) director to the
Board pursuant to this Section 3.04(b). The rights granted to each Initial
Shareholder pursuant to this Section 3.04(b) shall not be effective with respect
to any Initial Shareholder that has the right to nominate for election two (2)
or more directors to the Board pursuant to Section 3.04(a), or that has
transferred its rights under Section 3.04(a) pursuant to Section 3.13(a).

<PAGE>

                  (c) If at any time a Shareholder shall hold more than fifty
percent (50%) of the Outstanding Shares of the Company, all of the Shareholders
shall promptly take such actions as may be reasonably required to increase the
number of directors on the Board to such number as to permit such Shareholder to
nominate for election a majority of the directors of the Board; provided, that
any increase in the number of directors on the Board pursuant to this Section
3.04(c) shall be effected without detriment to the rights of Shareholders under
Sections 3.04(a) and 3.04(b) above. Upon the occurrence of the One Director
Date, if the number of directors on the Board is six (6) and there are two Veto
Shareholders, all of the Shareholders shall promptly take such actions as may be
reasonably required to decrease the number of directors on the Board to five
(5). Thereafter, all of the Shareholders shall promptly take such action as may
be necessary to increase the number of directors on the Board by one (1) member
to a total of six (6) members if the number of Veto Shareholders is increased to
three (3).

                  (d) No failure to elect a director at an annual or special
meeting of the shareholders of the Company shall prevent any Shareholder from
thereafter nominating a director to fill such vacancy or shall constitute a
waiver of such party's rights under this Section 3.04.

                  (e) Each Shareholder agrees to vote any Shares owned by it to
cause the election of each director nominated to the Board in accordance with
this Section 3.04, and the Company agrees to take all necessary action
reasonably necessary to cause the election of each such nominee to the Board.

                  Section 3.05. Removal of Directors. (a) Upon the written
request of BCI Investments, each Shareholder shall consent in writing to the
removal of any of the BCI Directors and shall take or cause to be taken all
actions necessary to remove such BCI Directors, and any replacement for such
removed BCI Directors shall be nominated and elected as provided in Sections
3.06(a) and 3.06(c).

                  (b) Upon the written request of AM Latin America, each
Shareholder shall consent in writing to the removal of any of the AM Latin
America Directors and shall take or cause to be taken all actions necessary to
remove such AM Latin America Directors, and any replacement for such removed AM
Latin America Directors shall be nominated and elected as provided in Sections
3.06(a) and 3.06(c).

                  (c) Upon the written request of SBCI Brazil Holding, each
Shareholder shall consent in writing to the removal of any of the SBCI Directors
(if any) and shall take or cause to be taken all actions necessary to remove
such SBCI Directors, and any replacement for such removed SBCI Directors shall
be nominated and elected as provided in Section 3.06(a) and 3.06(c).

                  (d) In the event that (A) the percentage of Outstanding Shares
held by any Initial Shareholder is reduced from twenty percent (20%) or greater
to below twenty percent (20%) (but such percentage is equal to or exceeds ten
percent (10%) of the Outstanding Shares of the Company, and as a result such
Initial Shareholder forfeits its existing rights under Section 3.04(a) (and its
rights under Section 3.04(b) become effective), or (B) the percentage of
Outstanding Shares held by (x) BCI Investments or AM Latin America is reduced
from a percentage that is less than twenty percent (20%) but at least ten
percent (10%) to less than ten percent (10%) of the Outstanding Shares, or (y)
SBCI Brazil Holding is reduced after the One Director Date from a percentage
that is less than twenty percent (20%) but at least ten percent (10%) to less
than ten percent (10%) of the Outstanding Shares, and, in either case, as a
result such Initial Shareholder forfeits its existing rights under Section
3.04(b), upon the written request of any Shareholder, such Initial Shareholder
shall be deemed to have consented in writing to the removal of one (1) of the
directors nominated by it (or if the case of sub-clause (A) arises prior to the
earlier of the One Director Date or the Two Director Date, two (2) directors
nominated by it), and all Shareholders shall take such action as may be
necessary to remove such director or directors. Any replacement for such removed
director shall be nominated and elected as provided in Sections 3.06(b) and
3.06(c).

<PAGE>

                  (e) In the event that the percentage of Outstanding Shares
held by any Initial Shareholder is reduced from twenty percent (20%) or greater
to less than ten percent (10%) of the Outstanding Shares, and as a result such
Initial Shareholder forfeits its existing rights under Section 3.04(a) and
potential rights under Section 3.04(b), upon the written request of any
Shareholder, such Initial Shareholder shall be deemed to have consented in
writing to the removal of two (2) of the directors nominated by it (or, prior to
the occurrence of the earlier of the One Director Date or the Two Director Date,
three (3) directors nominated by it), and all Shareholders shall take such
action as may be necessary to remove such directors. Any replacements for such
removed directors shall be nominated and elected as provided in Sections 3.06(b)
and 3.06(c).

                  (f) For so long as any Shareholder is a Defaulting
Shareholder, any other Shareholder may request in writing the removal of the
directors nominated by such Defaulting Shareholder pursuant to Section 3.03,
3.04(a) or 3.04(b). Upon such request, each Shareholder shall consent in writing
to the removal of such directors and shall take or cause to be taken all actions
necessary to remove such directors. Any replacements for such directors shall be
nominated and elected as provided in Sections 3.06(b) and 3.06(c).

                  (g) In the event that the number of directors on the Board is
reduced to five (5) pursuant to Section 3.04(c), or if the Two Director Date
occurs on or prior to the One Director Date, each Veto Shareholder shall be
deemed to have consented in writing to the removal of one of the directors
nominated by it, and all Shareholders shall take such action as may be necessary
to remove such director.

                  Section 3.06. Vacancies. (a) In the event that a vacancy is
created on the Board at any time by the death, disability, retirement,
resignation or removal of any director (other than removal pursuant to Sections
3.05(d) or 3.05(e) or 3.05(f)), the Shareholder that nominated such director
shall have the right to nominate a replacement director to fill such vacancy.

                  (b) Subject to the provisions of Section 3.13, in the event
that a vacancy is created on the Board at any time by the removal of any
director or directors pursuant to Section 3.05(d) or 3.05(e) or 3.05(f), the
determination as to which Shareholder or Shareholders shall have the right to
nominate a replacement director or directors to fill such vacancy shall be made
on the basis that representation on the Board shall be proportionate to each
Shareholders' percentage holdings of the Outstanding Shares, subject to the
rights of any Shareholder under Section 3.04.

<PAGE>

                  (c) Each Shareholder agrees to vote any and all Shares owned
by it to cause the election of each such replacement nominee to the Board, and
the Company agrees to take all necessary action promptly to cause the election
of each such replacement nominee to the Board. In the event the Shareholder
having the right to nominate a replacement director shall not have nominated a
replacement director to fill such vacancy at the time of the next following
meeting of the Board and such replacement director is necessary in order for a
quorum of the Board to be present, the other Shareholders shall have the right
to nominate a director to serve on the Board until such Shareholder shall
nominate the replacement.

                  Section 3.07. Covenant to Vote. Each Shareholder shall use,
from and after the date hereof, its best efforts and take all actions necessary
to call, or cause the Company and the appropriate officers and directors of the
Company to call, a special or annual meeting of the Shareholders and to vote all
Shares owned or held of record by such Shareholder at any such annual or special
meeting in favor of all actions, or take all actions by written consent in lieu
of any such meeting, necessary to effect the intent of this Article III. In
addition, each Shareholder agrees to vote the Shares owned or held of record by
such Shareholder upon any other matter arising under this Agreement submitted to
a vote of the Shareholders in a manner so as to implement the terms of this
Agreement.

                  Section 3.08. Action by the Board. (a) Except as otherwise
provided in this Section 3.08 or by Law:

          (i) meetings of the Board shall be held at least quarterly;

          (ii) a majority of directors shall be present in person or by
     telephone at any meeting of the Board, with at least one (1) director
     nominated by each Veto Shareholder present, in order to constitute a quorum
     for the transaction of business at such meeting; provided, however, that in
     the event a quorum is not present at any meeting of the Board at which the
     transaction of business does not require a Qualified Vote pursuant to
     Section 3.08(b), then such matter shall be postponed to a Board meeting to
     be held five (5) Business Days after the first meeting at which the
     presence of a majority of directors in person or by telephone shall
     constitute a quorum for the transaction of business at such second Board
     meeting; and

          (iii) all actions of the Board shall require the affirmative vote of
     the majority of the directors present and entitled to vote on the action

     quorum is present or, in lieu of a meeting, by the unanimous written
     consent of the members of the Board.

                  (b) Notwithstanding the provisions of Section 3.08(a) and
notwithstanding that no vote may be required, or that a lesser percentage vote
may be required, by Law or otherwise, the Company (except as provided below at
the end of this subsection or in Section 5.05(b) or (e)) shall not take, and no
party to this Agreement shall cause the Company to take, any action without the

permitted to nominate two (2) or more directors to the Board pursuant to Section

     the first sentence of Section 5.14(a); and

          (xx) the taking of any action, directly or indirectly, in
     contemplation of any of the foregoing; provided, that, for the avoidance of
     doubt, no such action shall impede the exercise by any Person that controls
     any Regulated Opco to exercise its voting rights with respect to such
     Regulated Opco.

provided, however, that a Qualified Vote will not require the affirmative vote
of a Defaulting Shareholder or a director nominated by any Shareholder that, at
the time of such vote, is a Defaulting Shareholder and such Shareholder need not
be present at a meeting of the Shareholders, in order to achieve a quorum for a
meeting to take action on a matter requiring a Qualified Vote; [ ].

                  Section 3.09. Action by Shareholders. (a) Except as otherwise
provided in this Section 3.09:

          (i) meetings of the Shareholders will only be held when action by the
     Shareholders is required by Law or if called by the Board to obtain any
     approval of a matter requiring a Qualified Vote;

          (ii) Shareholders holding a majority of the Outstanding Shares
     entitled to vote (which majority shall include all of the Veto
     Shareholders) shall be present in person, by proxy or by telephone at any
     meeting of the Shareholders in order to constitute a quorum for the
     transaction of business at such meeting and all actions of the Shareholders
     shall require the affirmative vote of the majority of Shareholders present
     and entitled to vote determined by voting interests at a duly convened
     meeting of the Shareholders at which a quorum is present; provided,
     however, that in the event any Veto Shareholder is not present at --------
     ------- any duly called meeting of Shareholders at which the transaction of
     business does not require a Qualified Vote pursuant to Section 3.08(b),
     then any such matters to be submitted to a vote of Shareholders at such
     meeting shall be postponed to a meeting of Shareholders to be held five (5)
     Business Days after the first meeting at which second meeting the presence
     of Shareholders holding a majority of the Outstanding Shares of the Company
     shall constitute a quorum for the approval of such matters; and

          (iii) notwithstanding any other provision to the contrary, the Company
     shall not take any action without the approval of each Veto Shareholder
     with respect to any action that requires the approval of Shareholders by
     Law and, subject to Section 3.08(b), the Company shall not take any action
     on any matter requiring a Qualified Vote of the Shareholders without the
     approval of each Veto Shareholder.

directors of any Regulated Opco, analogous to those described in Section
3.08(b), to be presented to the Board for discussion and a non-binding vote
recommending that such proposal be adopted or declined; provided, that a
recommendation that any such proposal be adopted must be approved by a Qualified
Vote of the Board. Nothing in this Section 3.09(b), however, shall obligate the
shareholders or the board of directors of any Regulated Opco, or any member of
such a board of directors, to vote in favor of any particular position or in any
particular manner.

                  (c) Each of the Shareholders shall use its best efforts to
cause information that is made generally available to the shareholders and/or
directors of each of the Opcos (including any monthly or other periodic
management reports delivered to the respective boards of directors of each of
the Opcos) to be provided to the Board on a timely basis, except to the extent
that confidentiality restrictions with respect to such information would prevent
the Opcos, their respective boards of directors or the Shareholders from
delivering such information to the Board.

                  (d) Notwithstanding any other provision of this Agreement and
notwithstanding that no vote may be required, or that a lesser percentage vote
may be required, by Law or otherwise, the Company shall not take, and no party
to this Agreement shall cause the Company to take, any action without the
affirmative vote of each Initial Shareholder holding at least ten percent (10%)
of the Outstanding Shares of the Company with respect to the following actions:

          (i) a material change in the nature or scope of the business or
     corporate strategy of the Company or any Intermediate Company or the

     with any Person; and

          (ii) the winding up or dissolution of the Company or any Intermediate

     existing or future law of any jurisdiction relating to bankruptcy,
     insolvency, reorganization or relief of debtors seeking to have an order
     for relief entered with respect to the Company or any Intermediate Company,

     Company, or for all or any part of its assets, or making a general
     assignment for the benefit of the creditors of the Company or any
     Intermediate Company;

provided, however, that the affirmative vote of any Initial Shareholder holding
at least ten percent (10%) of the Outstanding Shares of the Company shall not be
required if such Initial Shareholder, at the time of such vote, is a Defaulting
Shareholder, and such Initial Shareholder need not be present at a meeting of
the Shareholders, in order to achieve a quorum for a meeting to take action on
any of the matters specified in this Section 3.09(d).

                  Section 3.10. Business Plan. Attached hereto as Exhibit C is
the initial Business Plan of the Company for the period through December 31,
2002 (the "Initial Business Plan"). The Initial Business Plan has been approved
by the parties hereto.

                  Section 3.11. Management. (a) During the term of this
Agreement the Senior Officers shall be selected by mutual agreement of the Veto
Shareholders; provided, that for so long as AM Latin America is a Veto

Shareholder, BCI Investments shall have the sole right to nominate the chief
financial officer of the Company.

<PAGE>

                  (b) The Senior Officers shall report to the Board. The Senior
Officers shall nominate the remaining senior management of the Company and shall
nominate the senior management of the Intermediate Companies; provided, however,
for the avoidance of doubt, that members of senior management so nominated at
any Intermediate Company shall receive instructions solely from the board of
directors of the Intermediate Company to which such persons are appointed as
manager . To the extent permitted by applicable contractual and regulatory
restrictions, the chief executive officer, chief financial officer and chief
operating officer of each Opco (other than the Regulated Opcos) shall be
nominated by a majority of directors of the Board present at any meeting of the
Board.

                  (c) Accounting Matters. The parties agree that the Company and
each Subnewco shall be a calendar year company, will keep its books in
accordance with U.S. GAAP and will prepare the Financial Statements and the
Interim Financial Statements in accordance with U.S. GAAP. The initial auditors
of the Company shall be Deloitte & Touche LLP. Subsequent auditors shall be
appointed by decision of a majority of directors of the Board present at any
meeting of the Board.

                  Section 3.12. Removal of Senior Officers. Upon the written
request of Shareholders that hold, in the aggregate, a majority of the Equity
Interests of the Company, any Senior Officer may be removed, and each
Shareholder shall take or cause to be taken all actions necessary to remove any
such Senior Officer. Any replacement for such removed Senior Officer shall be
selected in accordance with Section 3.11.

                  Section 3.13. Transferability of Certain Governance Rights.
(a) In connection with the transfer by an Initial Shareholder to any one (1)
Person of twenty percent (20%) or more of the Outstanding Shares in one or more
transactions in accordance with the requirements of Article IV, such Initial
Shareholder by prior written notice to all of the parties hereto, and upon
transfer of such twenty percent (20%) interest, may transfer its existing right
(if any) to nominate three (3) directors or, as the case may be, two (2)
directors, to the Board as provided in Section 3.04(a) to such Person (the "Veto
Transferee"); provided, however, that the right of an Initial Shareholder to
regain the right to nominate three (3) directors or, as the case may be, two (2)
directors, to the Board following a forfeiture of such right pursuant to Section
3.04(a) shall not be transferable, and any purported transfer of such right to
any Person shall be null and void. In the event such Initial Shareholder validly
transfers its transferable rights under Section 3.04(a), such rights may be
subsequently transferred by any subsequent Veto Transferee, subject to the
restrictions applicable to an Initial Shareholder under this Section 3.13(a). On
transferring such right, the transferring Initial Shareholder shall forfeit any
rights it may have enjoyed under Section 3.04(b) and, for the avoidance of
doubt, Section 3.04(a). Veto Transferees shall enjoy the rights, subject to the
obligations, of the transferring Initial Shareholder under Sections 3.04, 3.05,
3.06, 3.08, 3.09, 3.11 and 3.13 hereof and shall otherwise be subject to the
obligations of a Shareholder in accordance with Section 4.06 hereof; provided,
that the rights of the transferring Initial Shareholder under Section 3.08 may
not be transferred to a Person listed in Schedule 3.13 hereto (or to any
Affiliate or successor of any such Person) without the prior written consent of
each Veto Shareholder. For the avoidance of doubt, in no event shall there ever
be more than two (2) Veto Shareholders, except if SBCI Brazil Holding becomes a
Veto Shareholder, in which case there shall never be more than three (3) Veto
Shareholders.

<PAGE>

                  (b) In connection with the transfer (x) by BCI Investments or
AM Latin America at any time, or (y) by SBCI Brazil Holding after the earlier to
occur of the One Director Date or the Two Director Date, to any one (1) Person
of less than twenty percent (20%) but more than ten percent (10%) of the
Outstanding Shares in one or more transactions in accordance with the
requirements of Article IV, such Initial Shareholder by prior written notice to
all of the parties hereto, and upon transfer of such interest, may transfer to
such Person (the "Director Transferee") its existing right (if any) to nominate
one director to the Board set forth in Section 3.04(b); provided, however, that
the right of an Initial Shareholder to regain the right to nominate one (1)
director to the Board following a forfeiture of such right pursuant to Section
3.04(b) shall not be transferable, and any purported transfer of such right to
any Person shall be null and void. On transferring such right, the transferring
Initial Shareholder (and any subsequent transferring Director Transferee) shall
forfeit any rights it may have enjoyed under Section 3.04(b) and, for the
avoidance of doubt, Section 3.04(a). In the event such Initial Shareholder
validly transfers its transferable rights under Section 3.04(b), such rights, in
addition to all rights as a Shareholder, may be subsequently transferred by any
subsequent Director Transferee, subject to the restrictions applicable to an
Initial Shareholder under this Section 3.13(b). The Director Transferee shall
enjoy the rights, subject to the obligations, of the transferring Initial
Shareholder under Sections 3.04(b), 3.05, 3.06, 3.09(d) and 3.13 hereof and
shall otherwise be subject to the obligations of a Shareholder in accordance
with Section 4.06 hereof; provided, that the rights of the transferring Initial
Shareholder under 3.09(d) may not be transferred to a Person listed in Schedule
3.13 hereto (or to any Affiliate or successor of any such Person) without the
prior written consent of each Veto Shareholder.

                                   ARTICLE IV

                            RESTRICTIONS ON TRANSFER

                  Section 4.01. General Restriction. (a) Except as provided in
Section 4.05, each Shareholder agrees that it will not, directly or indirectly,
make or solicit any Sale of, or create, incur, solicit or assume any Encumbrance
with respect to, any Equity Interest in the Company beneficially owned, directly
or indirectly, by such Shareholder other than (i) any Sale by an Initial
Shareholder or Permitted Transferee of such Initial Shareholder of, in the
aggregate, not more than ten percent (10%) of the total Equity Interests of the

procedures, and subject to the limitations, set forth in Sections 4.01, 4.03 and
4.06; or (ii) any Sale of Shares (or other Equity Interests of the Company)

in the Company shall be made in compliance with the Securities Act and other
applicable securities Laws of any other country.

                  (b) Notwithstanding anything to the contrary contained herein,
each Shareholder agrees that it will not, directly or indirectly, make or
solicit any Sale of any Equity Interest in the Company or any Intermediate
Company or Regulated Opco beneficially owned, directly or indirectly, by such
Shareholder which would be reasonably likely to result in a change of control of
any Regulated Opco in conflict with any Law applicable to the Company or any
Intermediate Company or Regulated Opco or any of their respective properties,
including, without limitation, applicable Brazilian Law, without the prior
written consent of the other Shareholders, which consent may be withheld in such
other Shareholders' sole discretion. Other than by means of a sale of Shares, no
Shareholder shall, directly or indirectly, make or solicit the Sale of, or
create, incur or assume any Encumbrance with respect to, any Equity Interest in
any Subnewco, any Intermediate Company listed in Schedule 3.03(a) of the
Disclosure Schedules of each Venturer (as defined in the Joint Venture
Agreement) or any Regulated Opco, which Equity Interest is beneficially owned,
directly or indirectly, by such Shareholder, except as provided in Section 5.11
or with the prior express written consent of each Veto Shareholder.

<PAGE>

                  Section 4.02. Legends. (a) The Company shall affix to each
certificate evidencing Shares a legend in substantially the following form:

                  THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                  UNDER THE SECURITIES LAWS OF ANY CANADIAN PROVINCE OR
                  TERRITORY. NO REGISTRATION OF TRANSFER OF SUCH SECURITIES WILL
                  BE MADE ON THE BOOKS OF THE ISSUER UNLESS SUCH TRANSFER IS
                  MADE IN CONNECTION WITH AN EFFECTIVE REGISTRATION STATEMENT
                  UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM THE
                  REGISTRATION REQUIREMENTS OF SUCH ACT OR SUCH ACT DOES NOT
                  APPLY.

                  THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO
                  CERTAIN RESTRICTIONS ON TRANSFER AS SET FORTH IN A
                  SHAREHOLDERS AGREEMENT, DATED AS OF NOVEMBER 16, 2000, AS IT
                  MAY THEREAFTER BE AMENDED, A COPY OF WHICH IS ON FILE AT THE
                  PRINCIPAL EXECUTIVE OFFICES OF THE ISSUER. NO REGISTRATION OF
                  TRANSFER OF SUCH SECURITIES WILL BE MADE ON THE BOOKS OF THE
                  ISSUER UNLESS AND UNTIL SUCH RESTRICTIONS SHALL HAVE BEEN
                  COMPLIED WITH.

                  THE HOLDER OF THE SECURITIES EVIDENCED BY THIS CERTIFICATE IS
                  ENTITLED TO CERTAIN RIGHTS AND SUBJECT TO CERTAIN OBLIGATIONS
                  AS SET FORTH IN A SHAREHOLDERS AGREEMENT, DATED AS OF NOVEMBER
                  16, 2000, AS IT MAY THEREAFTER BE AMENDED, A COPY OF WHICH IS
                  ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF THE ISSUER.

                  (b) In the event that any Shares shall cease to be Restricted
Shares, the Company shall, upon the written request of the holder thereof, issue
to such holder a new certificate evidencing such Shares without the first
paragraph of the legend required by Section 4.02(a) endorsed thereon; provided,
however, that such holder shall furnish the Company or its transfer agent such
certificates, legal opinions or other information as the Company or its transfer
agent may reasonably require to confirm that the legend is not required on such
certificate.

<PAGE>

                  (c) If any Shares held by a Shareholder shall cease to be
subject to the restrictions on transfer set forth in this Agreement, the Company
shall, upon the written request of such Shareholder, issue to such Shareholder a
new certificate evidencing such Shares without the second paragraph of the
legend required by Section 4.02(a). If any Shares shall cease to be entitled to
any rights and subject to any obligations set forth in this Agreement, the
Company shall, upon the written request of any Shareholder, issue to the holder
thereof a new certificate evidencing such Shares without the third paragraph of
the legend required by Section 4.02(a).

                  Section 4.03. Rights of First Offer. (a) (i) If, at any time,
any Shareholder (the "Selling Shareholder") shall desire to sell, directly or
indirectly, any or all of the Shares (or other Equity Interests in the Company)
owned by it (the "Offered Shares"), such Selling Shareholder shall deliver a
written notice of its intention to engage in such a Sale of the Offered Shares
(a "Notice of Intention"), accompanied by a copy of a proposal relating to such
Sale, to each of the other Shareholders (the "First Offer Shareholders"), as
well as to the Company, setting forth such Selling Shareholder's intention to
make such Sale, the number of Offered Shares, the price at which such Selling
Shareholder proposes to sell the Offered Shares (the "First Offer Price"),
whether such Selling Shareholder is only prepared to sell all and not part of
the Offered Shares and all other material terms and conditions of the offer. A
Notice of Intention, once given, shall be irrevocable. The Notice of Intention
shall be dated the date it is delivered by the Selling Shareholder to the First
Offer Shareholders and the Company.

          (ii) Upon receipt of the Notice of Intention, each First Offer
     Shareholder shall have the right to purchase at the First Offer Price (it
     being specifically agreed that the consideration may be in the form of
     cash, Cash Equivalents or Marketable Securities), subject to any
     requirement by the Selling Shareholder that it is willing only to sell all
     and not part of the Offered Shares, such number of Shares up to the Pro
     Rata Number for such Shareholder; provided, however, that the First Offer
     Shareholder may request the right to purchase an additional amount of
     Offered Shares as indicated in the Notice of Exercise (as defined below)
     given by such First Offer Shareholder. The right of the First Offer
     Shareholders pursuant to this Section 4.03(a)(ii) shall be exercisable by
     written notice to the Selling Shareholder (the "Notice of Exercise"), which
     notice shall state the maximum number of Offered Shares the First Offer
     Shareholder is willing to buy, with copies to each of the other First Offer
     Shareholders and the Company, within 20 days from the date of the Notice of
     Intention (the "First Offer Shareholder Option Period"). The right of the
     First Offer Shareholders pursuant to this Section 4.03(a)(ii) shall
     terminate if it is not exercised within 20 days of the date of the Notice
     of Intention. A Notice of Exercise, once given, shall be irrevocable.

          (iii) Upon receipt of the Notices of Exercise, the Selling Shareholder
     shall promptly calculate the number of Offered Shares which each First
     Offer Shareholder is entitled to purchase. If the Notices of Exercise
     indicate that each First Offer Shareholder wishes to purchase at least its
     Pro Rata Number, the Offered Shares shall be allocated among the First
     Offer Shareholders pro rata. If the Notices of Exercise indicate that one
     or more First Offer Shareholders do not wish to purchase their Pro Rata
     Number, such of the Offered Shares as are not taken up shall be allocated
     on a pro rata basis among the First Offer Shareholders who shall have
     indicated that they wish to purchase more than their Pro Rata Number;
     provided, however, that no such Shareholder shall be obligated to purchase
     more Offered Shares than such Shareholder shall have indicated it is
     willing to purchase in its Notice of Exercise.

<PAGE>

          (iv) In the event the calculations made in accordance with Section
     4.03(a)(iii) would result in the First Offer Shareholders purchasing all or
     (except where the Notice of Intention stated that the Selling Shareholder
     was prepared to sell all but not part of the Offered Shares) part of the
     Offered Shares, the Selling Shareholder shall sell the Offered Shares to
     such First Offer Shareholders on the date one hundred ten (110) days
     following the date of the Notice of Intention, or such other date as may be
     agreed by the Selling Shareholder and the relevant First Offer Shareholders
     (the "Settlement Date").

          (v) Upon the consummation of any purchase and Sale pursuant to this
     Section 4.03(a), the Selling Shareholder shall deliver certificates
     evidencing the Offered Shares sold duly endorsed, or accompanied by written
     instruments of transfer, in form and substance satisfactory to the
     purchaser, duly executed by the Selling Shareholder, free and clear of any
     Encumbrance, against delivery of the purchase price for such shares payable
     in (i) immediately available funds by wire transfer or check, (ii) Cash
     Equivalents or (iii) Marketable Securities. Notwithstanding the foregoing
     provisions of this Section 4.03(a), unless the Selling Shareholder shall
     have consented to the purchase of less than all of the Offered Shares, no
     First Offer Shareholder may purchase any Offered Shares unless all of the
     Offered Shares are to be purchased.

          (vi) In the event that payment with respect to the Offered Shares is
     to be made in whole or in part in Cash Equivalents or Marketable
     Securities, the value of such Cash Equivalents or Marketable Securities
     shall be the Closing Price of such Cash Equivalents or Marketable
     Securities as of the Settlement Date.

                  (b) In the event the First Offer Shareholders do not exercise
their options to purchase any or all of the Offered Shares and the Selling
Shareholder receives a bona fide offer or offers to purchase or otherwise
acquire the Offered Shares held by such Shareholder, then the Selling
Shareholder shall have the right (subject to the requirements of this Article
IV), for a period of ninety (90) days from the expiration of the First Offer
Shareholder Option Period, to enter into an agreement to sell the Offered Shares
for cash, Cash Equivalents or Marketable Securities at a price not less than the
First Offer Price and on such other terms as set forth in the Notice of
Intention. The Selling Shareholder shall as promptly as practicable sell the
Offered Shares or any remaining Offered Shares, as the case may be, after it
enters into an agreement to sell such Offered Shares, but in any event not later
than ninety (90) days after the date on which the Selling Shareholder enters
into an agreement to sell such Offered Shares.

                  (c) In the event the Selling Shareholder for any reason shall
not have entered into an agreement to sell all or the remaining Offered Shares
before the expiration of the first ninety (90)-day period described in Section
4.03(b) or shall not have sold the Offered Shares or the remaining Offered
Shares, as the case may be, before the expiration of the second ninety (90)-day
period described in Section 4.03(b), such Selling Shareholder shall not sell the
remaining Offered Shares without again complying with the provisions of this
Section 4.03.

                  Section 4.04. Right to Participate in Certain Dispositions.
(a) Subject to Section 4.03, at any time a Shareholder or group of Shareholders
(the "Divesting Shareholder(s)") receives or solicits a bona fide offer or
offers to purchase or otherwise acquire (an "Offer") Shares (or other Equity
Interests in the Company) representing more than forty percent (40%) of the
Outstanding Shares (or other Equity Interests in the Company) and beneficially
owned by such Divesting Shareholder(s) (the "Solicited Shares"), and the
Divesting Shareholder intends to sell such Solicited Shares, the Divesting
Shareholder(s) shall provide written notice (the "Offer Notice") of such Offer
to each of the other Shareholders (the "Tag-Along Shareholders") not later than
the 30th day prior to the consummation of the sale or other disposition
contemplated by the Offer. The Offer Notice shall identify the Solicited Shares,
the price offered for such Solicited Shares (it being specifically agreed that
the consideration may be in the form of cash, Cash Equivalents or Marketable
Securities) and all other material terms and conditions of the Offer (including
any estimated fees or expenses to be shared among the Divesting Shareholder(s)
and any Tag-Along Shareholders pursuant to Section 4.04(c) below), as well as a
copy of the Offer. Each of the Tag-Along Shareholders shall have the right and
option, for a period of twenty-five (25) days after the date the Offer Notice is
given to such Tag-Along Shareholders (the "Notice Period"), to notify the
Divesting Shareholder(s) of such Tag-Along Shareholder's interest in selling or
otherwise disposing of up to the Pro Rata Number of such Tag-Along Shareholder's
Shares (or other Equity Interests) pursuant to the Offer. Each Tag-Along
Shareholder desiring to exercise such option shall, prior to the expiration of
the Notice Period, provide the Divesting Shareholder(s) with a written notice
specifying the number of Shares (or other Equity Interests) which such Tag-Along
Shareholder has an interest in selling or otherwise disposing of pursuant to the
Offer (a "Notice of Interest"), and shall deliver to the Divesting
Shareholder(s) the certificate or certificates evidencing the Shares (or other
Equity Interests) to be sold or otherwise disposed of pursuant to such Offer by
such Tag-Along Shareholder duly endorsed in blank or accompanied by written
instruments of transfer in form satisfactory to the Divesting Shareholders(s)
executed by such Tag-Along Shareholder and delivery of such certificate or
certificates evidencing the Shares (or other Equity Interests) to be sold, shall
constitute an irrevocable election by such Tag-Along Shareholder to authorize
and permit the Divesting Shareholder(s) to sell such Shares (or other Equity
Interests), on behalf of such Tag-Along Shareholder, pursuant to the Offer.
<PAGE>

                  (b) If the Person(s) making the Offer is or are unwilling to
buy all the Solicited Shares plus all the Shares tendered by Tag-Along
Shareholders in their Notices of Interest, then the Divesting Shareholder(s) and
each Tag-Along Shareholder who wishes to sell shall be entitled to sell a number
of Shares equal to the Pro Rata Number. If any Tag-Along Shareholder wishes to
sell less than all the Shares it is entitled to sell in accordance with the
preceding sentence, the Shares it declines to sell shall be allocated among the
Divesting Shareholder(s) and the Tag-Along Shareholders who wish to sell
additional Shares according to the same formula, mutatis mutandis. The Divesting
Shareholder(s) shall not effect the Sale of any Shares pursuant to the Offer
unless all the Solicited Shares and all of the Shares tendered to the Divesting
Shareholder(s) and entitled to be sold pursuant to this Section 4.04 are
simultaneously sold.

                  (c) As promptly as practicable after the consummation of the
sale or other disposition of the Shares of the Divesting Shareholder(s) and the
Shares of the Tag-Along Shareholders pursuant to the Offer, the Divesting
Shareholder(s) shall remit to each of the Tag-Along Shareholders the total sales
price of the Shares of such Tag-Along Shareholders sold or otherwise disposed of
pursuant thereto less a pro rata portion of the reasonable out-of-pocket fees
and expenses payable to any Person other than the Divesting Shareholder(s) and
its Affiliates (including, without limitation, reasonable legal expenses)
incurred by the Divesting Shareholder(s) in connection with such sale or
disposition.

                  (d) If at the end of the Notice Period any Tag-Along
Shareholder shall not have given a Notice of Interest (and delivered all other
required documents) with respect to some or all of the pro rata portion of such
Tag-Along Shareholder's Shares, such Tag-Along Shareholder will be deemed to
have waived all its rights under this Section 4.04. If, at any time the
Divesting Shareholder(s) abandons the proposed sale pursuant to the offer or at
the end of the 45-day period following the giving of the Offer Notice, the
Divesting Shareholder(s) has not completed the sale of all the Solicited Shares
and the Shares with respect to which Tag-Along Shareholders shall have given
Notices of Interest pursuant to this Section 4.04, the Divesting Shareholder(s)
shall promptly return to such Tag-Along Shareholders all certificates evidencing
the unsold Shares that such Tag-Along Shareholders delivered for sale or other
disposition pursuant to this Section 4.04 and the provisions of this Section
4.04 shall apply to any subsequent Sale by the Divesting Shareholder(s) of any
of the Shares initially proposed to be sold in the Offer; provided, however,
that if a Tag-Along Shareholder is unable, notwithstanding its best efforts, to
obtain any necessary consents to the sale of its Shares with respect to which it
has given a Notice of Interest pursuant to this Section 4.04 prior to the
anticipated consummation of the sale, the Divesting Shareholder shall not sell
any of the Solicited Shares prior to the 60th day following the date of the
Offer Notice unless (i) such Tag-Along Shareholder has ceased to use best
efforts to obtain such consents or (ii) such delay would prevent a Divesting
Shareholder from consummating the sale of its Solicited Shares.

                  (e) Except as expressly provided in this Section 4.04, no
Divesting Shareholder(s) shall have any obligation to any Tag-Along Shareholder
with respect to the Sale or other disposition of any Shares owned by such
Tag-Along Shareholder in connection with this Section 4.04. Anything herein to
the contrary notwithstanding and irrespective of whether any Notice of Interest
shall have been given, no Divesting Shareholder(s) shall have any obligation to
any Tag-Along Shareholder to sell or otherwise dispose of any Solicited Shares
pursuant to this Section 4.04 as a result of any decision by such Divesting
Shareholder(s) not to accept or consummate any Offer or Sale or other
disposition with respect to the Solicited Shares (it being understood that any
and all such decisions shall be made by such Divesting Shareholder(s) in its
sole discretion). No Tag-Along Shareholder shall be entitled to sell or
otherwise dispose of Shares directly pursuant to an Offer (it being understood
that all such sales and other dispositions shall be made only on the terms and
pursuant to the procedures set forth in this Section 4.04).

                  Section 4.05. Permitted Transfers. The first sentence of
Section 4.01(a), and Sections 4.03 and 4.04, and subclauses (b) and (c) of the
first sentence of Section 4.06, shall not be applicable to a Sale of Shares by a
Shareholder pursuant to which (a) such Shareholder transfers Shares to a
Permitted Transferee of such Shareholder in compliance with the terms hereof and
(b) the Sponsor Party of the transferring Shareholder (or BCI, if the Sponsor
Party of the transferring Shareholder is BCE, or SBCI, if the Sponsor Party of
the transferring Shareholder is SBCI Parent) guarantees the obligations of the
Permitted Transferee of the transferring Shareholder and enters into a guarantee
and share retention agreement, substantially in the form of Exhibit D to this
Agreement (the "Guarantee and Share Retention Agreement"); provided, that if BCI
or SBCI, as the case may be, does not hold, directly or indirectly, a majority
of economic and voting interest of their respective Permitted Transferees (a
"Sister Transferee"), the share retention obligations set forth in the Guarantee
and Share Retention Agreement shall not apply to such Sister Transferee and the
Guarantee and Share Retention Agreement entered into by BCI or SBCI in respect
of such Sister Transferee shall be modified accordingly; provided, further, that
in the event any transferee acquiring Shares pursuant to this Section 4.05 would
for any reason cease to be a Permitted Transferee, the Sponsor Party of such
transferee shall, prior to such cessation, cause such transferee to transfer all
Shares so acquired to a Permitted Transferee of such Sponsor Party, which
transfer shall comply with the terms of this Section 4.05 and clause (a) of the
first sentence of Section 4.06. The transferring Shareholder shall notify the
other Shareholders of any transfer of Shares to a Permitted Transferee and shall
provide evidence of its compliance with the provisions of this Section 4.05 and
clause (a) of the first sentence of Section 4.06, including delivery of an
executed Guarantee and Share Retention Agreement in accordance with this Section
4.05.

                  Section 4.06. Prospective Transferees; Guarantee and Share
Retention Agreement. Each Shareholder agrees that it will not directly or
indirectly make any Sale of, or create, incur or assume any Encumbrance with
respect to, any Shares held by such Shareholder unless, prior to the
consummation of any such Sale or the creation, incurrence or assumption of any
such Encumbrance, the Person to whom such Sale is proposed to be made or the
Person in whose favor such Encumbrance is proposed to be created, incurred or
assumed (for purposes of this Section 4.06, a "Prospective Transferee") (a)
executes and delivers to the Company an Accession Certificate in the form
attached as Exhibit E hereto (the "Accession Certificate"), whereby such
Prospective Transferee confirms that, with respect to the Shares that are the
subject of such Sale or Encumbrance, it shall be deemed to be a Shareholder for
the purposes of this Agreement and agrees to be bound by all the terms of this
Agreement, (b) causes its ultimate parent company to execute and deliver a
Guarantee and Share Retention Agreement, in form and substance reasonably
satisfactory to the Company and to agree to be bound by the provisions of
Sections 4.05, 5.05 and 5.07 and Article VI hereof, and (c) delivers to the
Company a written opinion of counsel, satisfactory in form and substance to the
Company, to the effect that the agreements referred to above are the legal,
valid and binding obligation of such Prospective Transferee and its ultimate
parent company, enforceable against such Prospective Transferee and its ultimate
parent company in accordance with their terms. The Company shall execute such
Accession Certificate upon verification that the terms of this Article IV have
been satisfied. Upon (i) satisfaction of the requirements of this Article IV,
(ii) the execution and delivery by such Prospective Transferee, the transferring
Shareholder and the Company of the Accession Certificate referred to in clause
(a) above, (iii) the execution and delivery of the agreement referred to in
clause (b) above, and (iv) the delivery of the opinion of counsel referred to in
clause (c) above, such Prospective Transferee shall be deemed a "Shareholder"
for the purposes of this Agreement, and shall have the rights and be subject to
the obligations of a Shareholder hereunder with respect to the Shares held by
such Prospective Transferee or in respect of which such Encumbrance shall have
been created, incurred or assumed.

                  Section 4.07. Improper Sale or Encumbrance. Any attempt to
make any Sale of, or create, incur or assume any Encumbrance with respect to,
any Shares not in compliance with this Agreement shall be null and void and the
Company shall not be required to give any effect in the Company's register of
members to such attempted Sale or Encumbrance.

                                   ARTICLE V

                              ADDITIONAL AGREEMENTS

                  Section 5.01. Financial Statements. The Company shall prepare
and deliver to each Shareholder (i) monthly Interim Financial Statements for
each fiscal month within 30 days of the end of each fiscal month and (ii)
quarterly Interim Financial Statements for each fiscal quarter within 45 days of
the end of each fiscal quarter. The Company shall prepare and deliver Financial
Statements to each of the Shareholders within 60 days of the end of each fiscal
year.

                  Section 5.02. Access to Information. From and after the date
of the Closing, the Company and each of the Company Subsidiaries will permit
representatives of any of the Shareholders, at such Shareholder's expense and
upon reasonable notice, to obtain all documents and other information in the
possession of the Company as may reasonably be requested in order to enable any
such Shareholder to monitor its investment in the Company and exercise its
rights under this Agreement.

                  Section 5.03. Confidential Information. During the Restricted
Period applicable to each Shareholder, each Shareholder agrees to keep all
Confidential Information confidential, except Confidential Information that (a)
is or becomes generally available to the public (other than as a result of a
disclosure by such Shareholder or any Affiliate of such Shareholder in breach of
this Agreement), (b) the Company agrees in writing may be disclosed, (c) the
Company or any Shareholder is required, pursuant to Law, regulation, legal
process or regulatory authority to disclose, (d) is developed independently by
such Shareholder and is not based on or derived from Confidential Information
previously disclosed by other Shareholders, or (e) is known to such Shareholder
prior to its disclosure to the Company. The term "Confidential Information"
means all information relating to trade secrets, price, customer and supplier
lists, pricing and marketing plans, policies and strategies, details of client
and consultant contracts, operations methods, product development techniques,
business acquisition plans, new personnel acquisition plans, investment
processes, systems, strategies and related data and all other confidential
information with respect to the Company or any Company Subsidiary. The parties
hereto agree and acknowledge that remedies at Law for any breach of their
obligations under this Section 5.03 are inadequate and that in addition thereto
the Company shall be entitled to seek equitable relief, including injunction and
specific performance, in the event of any such breach.

                  Section 5.04. Certain Issuances of New Securities. (a) If the
Company proposes to issue New Securities, other than pursuant to a bonus issue,
an initial public offering or other pro rata distribution to Shareholders, the
Company hereby grants to the Shareholders the right to purchase, in accordance
with Section 5.04(b), New Securities which the Company proposes to issue pro
rata, based on each Shareholder's Equity Interests in the Company.

                  (b) In the event that the Company proposes to issue New
Securities, subject to Section 5.04(a), the Company shall give each Shareholder
a written notice (a "Notice of Issuance") of its intention, describing all
material terms of the New Securities and the price and all material terms upon
which the Company proposes to issue such New Securities. Each Shareholder shall
have ten (10) Business Days from the date of the Notice of Issuance to agree to
purchase all or any portion of its pro rata share of such New Securities;
provided, however, that if the Company is proposing to issue New Securities for
consideration other than all cash, the Company shall accept from the
Shareholders either non-cash consideration that is reasonably comparable to the
non-cash consideration specified in the Notice of Issuance or cash in an amount
equal to the fair market value of the non-cash consideration which shall be
specified in the applicable Notice of Issuance. Any purchase by any Shareholder
of New Securities shall be consummated on the date on which all other New
Securities described in the applicable Notice of Issuance are issued.

                  (c) In the event that any Subnewco proposes to issue any
Capital Stock, each Shareholder shall, and shall cause each Subnewco to, grant
to the Company the right to purchase all such Capital Stock.

                  (d) In the event that any Intermediate Company or Regulated
Opco proposes to issue any Capital Stock, each Shareholder agrees, and shall
cause the Company and each Subnewco to agree, subject to Section 3.08(b), that
it shall cause the Company or the relevant Company Subsidiary to subscribe the
amount of such Capital Stock offered to it sufficient to prevent the reduction
of the percentage of the Capital Stock of such Intermediate Company or Regulated
Opco held by the Company or such Company Subsidiary.

                  Section 5.05. Referral of Opportunities. (a) The Shareholders

                  Section 5.06. Affiliate Transactions. Each Shareholder agrees
to use its best efforts to ensure that any transaction or agreement between or
among such Shareholder or any of its Affiliates and the Company, any Company
Subsidiary or any Minority Investee shall be on terms no less favorable to the
Company or any such Company Subsidiary or Minority Investee than the terms and
conditions generally offered by such Shareholder and its Affiliates, as the case
may be, to the most favored non-affiliated customers of such Shareholder or
Affiliates for transactions or agreements of a similar nature.

<PAGE>

                  Section 5.07. Consolidation of the Company and BCI. (a) The
Shareholders agree that as between the Company and BCI, there shall only ever be
one public company subject to the ongoing reporting obligations of sections 13
or 15(d) of the Exchange Act, except as may otherwise be provided in subsection
(c) of this Section 5.07. If BCI proposes that the Company pursuant to a
Qualified Offer be consolidated with, merged into, amalgamated with or otherwise
become controlled by the Surviving Entity pursuant to any merger, consolidation,
amalgamation, reorganization, exchange offer or similar transaction (the
"Consolidation"), BCI shall deliver to the parties hereto a written notice (the
"Consolidation Notice") setting forth all proposed material terms of such
Consolidation. Such proposed Consolidation may be effected by BCI in accordance
with this Section 5.07 only if (i) no adverse tax consequences arise from such
transaction which are material for any of the Shareholders or their successors,
assigns and transferees or a substantial portion of the other public
shareholders, if any, of the Company relative to their respective investment in
the Company, and (ii) all of the Qualified Offer Conditions set forth in Section
5.07(d) have been satisfied (the conditions set forth in subclauses (i) and
(ii), the "Consolidation Conditions"). To the extent reasonably requested by any
Shareholder after consideration of (i) any potential adverse tax consequences
arising from or related to such Consolidation and (ii) the ability of BCE to
discharge all of its obligations under the BCE Indemnity Agreement (as defined
below) based on the financial condition of BCE at the date of the Consolidation
Notice, BCI shall provide the Shareholders with (A) the written opinion of legal
counsel reasonably satisfactory to the Shareholders or (B) a ruling from the
applicable taxing authorities regarding the tax-free nature of the Consolidation
(which, in the case of each of (A) and (B), shall be reasonably satisfactory to
the Shareholders); failure to provide such requested ruling or opinion shall be
deemed to be a failure to satisfy the Consolidation Conditions. BCE shall agree
to indemnify the Shareholders (other than BCI Investments), their respective
Affiliates and Specified Assigns and certain successors, assigns and transferees
from any Losses associated with any adverse tax consequences arising as a result
of or relating to any such Consolidation by execution prior to Consolidation of
a separate instrument in respect thereof in the form set forth in Exhibit G
hereto (the "BCE Indemnity Agreement"). Unless the Shareholders unanimously
agree otherwise, the accounting policies, headquarters location, name,
management practices and other material characteristics of the Company in effect
prior to the Consolidation will be preserved following the Consolidation. Each
of BCE, BCI and BCI Investments shall permit each Shareholder and their
respective representatives and advisors to conduct reasonable due diligence
investigations of BCE, BCI and BCI Investments and their Subsidiaries relating
to the Consolidation to evaluate the tax consequences of any such transaction
and to determine whether the Qualified Offer Conditions have been satisfied.

                  (b) If BCI delivers a Consolidation Notice and the
Consolidation Conditions have been satisfied, the Shareholders agree that they
shall negotiate in good faith regarding the timing of consolidating the Company
into the Surviving Entity with the objective of causing the Company to effect
the Consolidation within one year from the date that the Consolidation
Conditions have been satisfied. If, after consultation with BCI Investments, any
Veto Shareholder reasonably concludes that market conditions are then adverse to
the Consolidation of the Company and BCI, each of AM Latin America and SBCI
Brazil Holding shall have the right to postpone such Consolidation until the
earlier of (i) such time as the Shareholders unanimously agree that market
conditions are favorable to such Consolidation or (ii) the first year
anniversary of the date that such Qualified Offer Conditions were first
satisfied in full. If such Consolidation has not occurred on or prior to the
termination of the period referred to in clause (ii) in the immediately
preceding sentence, subject to satisfaction of the Consolidation Conditions,
BCI, directly or indirectly, may deliver a Consolidation Notice and acquire all,
but not less than all, of the Shares pursuant to the Qualified Offer.

<PAGE>

                  (c) If prior to satisfaction of the Consolidation Conditions,
the AM Latin America Directors and the SBCI Directors (if any) have voted in
favor of an initial public offering of the Capital Stock of the Company at a
duly convened meeting of the Board (the "Approval Date"), and the BCI Directors
shall have voted against such initial public offering at such meeting of the
Board, the chief financial officer of BCI shall certify in writing to AM Latin
America and SBCI Brazil Holding whether it has reasonable commercial grounds
(other than its desire to preserve its opportunity hereunder to make a Qualified
Offer) for opposing such initial public offering, detailing any such grounds in
such certification within fifteen (15) days after exercising its veto right
under Section 3.08(b)(ii). If BCI Investments does not have reasonable
commercial grounds for opposing such initial public offering or otherwise fails
to deliver such certification, BCI Investments will have 180 days from the
Approval Date to satisfy the Consolidation Conditions and, subject to
satisfaction of the Consolidation Conditions, to make a Qualified Offer to the
Shareholders. In the event BCI Investments is unable to satisfy the
Consolidation Conditions within 180 days of the Approval Date, the Company shall
be permitted to undertake such initial public offering and BCI Investments,
together with the other Shareholders, shall take all necessary action to cause
the Company to undertake such initial public offering. If the Company completes
an initial public offering in accordance with the terms of this Section 5.07(c)
and the Consolidation Conditions are met at a future date, BCI Investments will
be entitled, subject to satisfaction of the Consolidation Conditions, to make a
Qualified Offer to the Shareholders. For greater certainty, except as
specifically set forth in this Section 5.07(c), each Veto Shareholder shall
retain its veto right under Section 3.08(b)(ii).

                  (d) Shareholders shall only be obliged to accept a Qualified
Offer if each of the conditions listed below (the "Qualified Offer Conditions")
are satisfied at the time of the Qualified Offer and at the time of
Consolidation. The Qualified Offer Conditions are:

          (i) BCI does not have any interests in any business or own any
     operating assets other than the Company;

          (ii) BCI has sufficient cash to meet all remaining obligations for
     payment under the terms of all of its outstanding Indebtedness, including
     any remaining obligations under its Promissory Note and Special Notes (the
     "Defeasance Amount") and shall have established a cash reserve in the
     amount of the Defeasance Amount to be used exclusively to pay such
     liabilities;

          (iii) BCI is listed on either the New York Stock Exchange or Nasdaq
     National Market System (or any other exchange acceptable to all the
     Shareholders);

<PAGE>

          (iv) Subject to Section 5.07(f) below, the number of Surviving Entity
     Shares offered to each Shareholder (other than BCI Investments and its
     Permitted Transferees) for each Share then held by each such Shareholder is
     equal to the Exchange Ratio and no new Surviving Entity Shares are offered
     or issued to BCI Investments in respect of its Shares;

          (v) all disproportionate voting rights shall have terminated, the
     voting rights of each Shareholder shall be commensurate with their economic
     interest in the Company and the transactions described in Section 5.11
     shall have been consummated;

          (vi) BCI Investments shall have complied with the provisions of
     Section 5.07(a) hereof;

          (vii) the Veto Shareholders and BCE will have entered into a
     registration rights agreement in the form of Exhibit F to this Agreement
     (the "Registration Rights Agreement"), which Registration Rights Agreement
     shall supercede the registration rights agreement, dated October 6, 1997,
     between BCE and BCI;

          (viii) BCI Investments is a Veto Shareholder and shall not have
     entered into any contract or other agreement to sell or otherwise dispose
     of its Shares;

          (ix) BCE and BCI shall have duly executed and delivered to each of the
     Shareholders, as indemnitees thereunder, the BCE Indemnity Agreement, and
     shall have delivered the related legal opinion of counsel reasonably
     acceptable to the Shareholders (other than BCI Investments) substantially
     in the form set forth in Exhibit H hereto;

          (x) BCE has consented in writing to the Consolidation; and

          (xi) BCE has entered into a Guarantee and Share Retention Agreement in
     a form reasonably acceptable to the Shareholders; provided, that BCE shall
     not be obligated to enter into such agreement if it is a direct shareholder
     of the Company (or the Surviving Entity) and covenants to enter into such
     an agreement in the event it ceases to be a direct shareholder of the
     Company or the Surviving Entity while maintaining a direct or indirect
     ownership interest in the Company or the Surviving Entity.

                  (e) Immediately following the Consolidation, BCE shall enter
into a shareholders agreement with the Shareholders hereunder, containing rights
and obligations substantially similar to those set forth in this Agreement, and
the rights and obligations of BCI Investments in the Transaction Documents shall
become the rights and obligations of BCE (other than BCI Investments's
obligations under its Promissory Note and its Special Notes, which shall have
been defeased by BCI on or prior to Consolidation).

                  (f) To the extent that, prior to the time of calculation of
the Exchange Ratio for purposes of Section 5.07(d)(iv), the Company has issued
any Equity Interests other than Common Stock or Series C Shares, or the
Surviving Entity has issued any Equity Interests other than Surviving Entity
Shares, the Shareholders will agree to amend the terms hereof and the BCE
Indemnity Agreement in such a manner as to give effect to the original intention
of the Shareholders with regard to (i) the ownership of economic and voting
interests in the Surviving Entity after the Consolidation and (ii) the economic
terms of, and the parties rights and obligations under, the BCE Indemnity
Agreement.

<PAGE>

                  (g) Promptly after receiving a Consolidation Notice, the
Shareholder and the Sponsor Parties shall make good faith efforts to consult
with BCI regarding any potential adverse tax consequences which may arise with
respect to the proposed Consolidation.

                  (h) In the event any Material Tax Change occurs after the date
of the Amended and Restated Joint Venture Agreement, the form of the BCE
Indemnity Agreement shall be amended by BCE and the parties hereto to provide
indemnification to the Shareholders regarding such Material Tax Change. If the
parties fail, after engaging in good faith negotiations, to agree to such
amendments or to the amendments referred to in Section 4.05(c) of the Initial
Joint Venture Agreement, BCI shall not be permitted to deliver a Consolidation
Notice or cause the Consolidation to be consummated.

                  (i) The Shareholders shall not implement any tax planning
measures designed solely to cause any proposed Consolidation to fail to satisfy
the first Consolidation Condition set forth in Section 5.07(a).

                  (j) AM Latin America and SBCI Brazil Holding shall have the
right to cause a redomiciliation and/or reorganization (the "Reorganization") of
the Company (or the Surviving Entity) either prior or subsequent to the
Consolidation if the Canadian corporate resident status of such entity creates
or would create any adverse Tax or other business, financial or economic
consequences (as determined by the Initial Shareholders, other than BCI
Investments) to any of such Shareholders, their respective Sponsor Parties, or
other Shareholders holding at least ten percent (10%) of the Outstanding Shares,
which consequences are material for any of such Shareholders or their respective
Sponsor Parties relative to their respective investments in the Company. For the
avoidance of doubt, if such Shareholders determine prior to the Consolidation
that the Canadian corporate resident status of the Company (or the Surviving
Entity) would create such adverse consequences, the Consolidation shall not be
effected until agreement has been reached with respect to the Reorganization;
provided, however, if BCI Investments agrees with SBCI Brazil Holding and AM
Latin America in respect of the Reorganization, nothing set forth in this
Section 5.07(j) shall otherwise permit SBCI Brazil Holding and AM Latin America
to prevent the Consolidation. The new situs of the Surviving Entity outside of
Canada and form of Reorganization shall be determined by negotiation among the
Shareholders holding at least ten percent (10%) of the Outstanding Shares acting
in good faith, with a view toward implementing the most Tax efficient corporate
structure for the Shareholders, their respective Sponsor Parties and the Company
(or the Surviving Entity) as a going concern. In considering the form of any
such Reorganization, the liabilities of all the parties that would arise in
connection with such Reorganization shall be taken into account. Any costs or
liabilities related to the Reorganization shall be borne by the Company (or the
Surviving Entity). If the Shareholders are unable to agree on the new situs
outside of Canada and/or the form of the Reorganization after good faith
negotiations, any party shall have the right to treat such lack of agreement as
a Dispute subject to Sections 6.14 and 6.15.

                  (k) Each Shareholder undertakes to cooperate with each other
Shareholder and to act in good faith with respect to the consummation of the
Consolidation and Reorganization (if any), including, without limitation, to
enter into any arrangement with a Tax authority if such arrangement would be
necessary to avoid any material Tax liabilities of such Shareholder and would
not otherwise have any significant adverse consequences to such Shareholder, its
Sponsor Party or any Affiliate of its Sponsor Party.

                  Section 5.08. Registration Rights. None of the Company, BCI
Investments, BCE or BCI, without the prior written consent of each of the Veto
Shareholders, shall enter into any agreement providing for registration rights
with respect to the Capital Stock of BCI or the Company other than the
Registration Rights Agreement.

                  Section 5.09. Voting Structure. [ ].

                  Section 5.10. Additional Capital Contributions. Subject to the
identification of appropriate business opportunities and the decision by each
Shareholder to pursue such opportunities, the Shareholders' current intention is
to consider opportunities to make available to the Company an additional $1.0
billion of investment capital to support the development of new projects,
subject to any veto rights of any of the Shareholders and, subject further, to
each Shareholder's absolute and unconditional right, in its sole discretion, to
change its current intention to consider making additional capital available to
the Company. It is understood that the first sentence of this Section 5.10 shall
not create any obligation on the part of any Shareholder or Sponsor Party to
make any additional investment capital available or to approve any capital
increase or create any right of the Company or any Shareholder to receive any
capital.

                  Section 5.11. Unwind. [ ].

                  Section 5.12. Future Acquisitions. Subject to applicable Law,
until the Unwind Date, all future acquisitions made by the Company or any
Company Subsidiary shall, to the extent permitted by applicable Law, be held by
the Company directly.

                  Section 5.13. Default. (a) If any Shareholder (a "Defaulting
Party") fails to make payment with respect to or to perform any Outstanding
Obligation or any share issuance approved pursuant to Section 3.08(b) and to
which such Shareholder has agreed to subscribe pursuant to Section 5.04(b)
within ten (10) Business Days of the date due (the "Due Date"), interest shall
accrue on any unpaid amount or, in the case of America Movil's Outstanding
Obligation to contribute the Techtel Amount (as defined in the Amended and
Restated Joint Venture Agreement) to the Company pursuant to Section 2.03(c) of
the Amended and Restated Joint Venture Agreement, on the value attributed to
such obligation (the "Default Amount") at a rate per annum of 200%, or, if
lower, the maximum rate permitted by applicable law (the "Default Rate") from
the Due Date until the date paid in full together with all interest accrued
thereon (based on the actual number of days elapsed over a 360-day year).

                  (b) Any Shareholder (an "Advancing Party") may upon written
notice to the other Shareholders and the Company, advance all or a portion of
the Default Amount in lieu of the Defaulting Party. If more than one Shareholder
provides such a notice, such Shareholders shall have the right to fund their pro
rata portion of the Default Amount, based on the percentage of Outstanding
Shares held by such Shareholders, or such other portion as may be agreed by such
Shareholders. In the event that any Shareholder advances all or a portion of the
Default Amount in lieu of a Defaulting Party, the obligation of the Defaulting
Party to make payment to the Company of the Default Amount, together with
accrued interest, shall be deemed assigned to the Advancing Party or Parties in
proportion to the percentage of the Default Amount advanced by such Advancing
Party.

<PAGE>

                  (c) In the event that the Defaulting Party has not made
payment in full of the Default Amount, together with all accrued interest, or
performed its Outstanding Obligations and paid all accrued interest owed
thereunder, to the Company or the Advancing Parties, as appropriate, within one
hundred eighty (180) days after the Due Date, the Company shall issue new Shares
to the Advancing Parties and, in the case of a default by a Defaulting
Shareholder under its Promissory Note or, if applicable, its Special Notes,
purchase, for a total amount of $1.00, an equal number of Shares previously
issued to the Defaulting Party in amounts sufficient to dilute the Equity
Interests of the Defaulting Party in the Company, and reflecting (i) any
advances made by Advancing Parties, (ii) amounts paid by other Shareholders
pursuant to the Outstanding Obligations or share issuance, as the case may be,
(iii) all interest accrued on the Default Amount pursuant to Section 5.13(a),
(iv) the fair market value of the Company at the Due Date, as determined in
accordance with clause (d) below, and (v) Equity Interests, if any, issued to
the other Shareholders at the time of such payment. All Shareholders will be
deemed to have consented to such issuance of Shares. For the purpose of
effecting a purchase of Shares in accordance with this Section 5.13(c), each
Shareholder hereby irrevocably appoints the Company to be its attorney, and in
its name and on its behalf to do all acts and things, execute any document or
complete any transfer that the Company may require in order to complete such
purchase, and each Shareholder hereby agrees to ratify and confirm any act of
the Company in connection therewith. Notwithstanding any such issuance of
Shares, all interest accrued on the Default Amount pursuant to Section 5.13(a)
at the time of such issuance (the "Default Interest Amount") shall be deemed due
and owing by the Defaulting Shareholder to the Company and interest shall accrue
on the Default Interest Amount at the Default Rate until the Default Interest
Amount, together with all interest accrued thereon, is paid in full.

                  (d) For purposes of the preceding clause (c), the fair market
value of the Company shall be determined in accordance with the following
procedure. Within ten (10) Business Days following the 180-day period referred
to in clause (c) above, the Defaulting Party shall select one of the investment
banks listed in Schedule 5.13, and the Company shall select one of the
investment banks listed in Schedule 5.13. In the event that none of the
investment banks listed in Schedule 5.13 accepts an engagement from the
Defaulting Party or the Company, as the case may be (through no fault of the
Defaulting Party or the Company, as the case may be) and there are no other
investment banks listed in Schedule 5.13 from whom such party may choose and
which are prepared to accept selection or referral, as the case may be, the
Defaulting Party or the Company, as the case may be, shall choose an investment
banking firm of international standing in the United States which does not, and
whose directors, officers, employees or Affiliates do not, have a direct or
indirect material financial interest for its proprietary account in the
Defaulting Party or the Company, as the case may be, or any of their respective
Affiliates. Within thirty (30) days of its acceptance of such selection, each
selected investment bank shall determine independently the fair market value of
the Company and provide such valuation in writing to each of the Shareholders
and the Company. If the difference between such two valuations is twenty percent
(20%) or less, the fair market value of the Company shall be deemed to be the
average of such two valuations. If the difference between such two valuations is
greater than twenty percent (20%), and if the Defaulting Party and the Company
are otherwise unable to agree which valuation is correct, within 270 days after
the Default Date the matter shall be referred by the Company to the Company's
accountants, which accountants shall select one of the two valuations as being
closest to the fair market value of the Company as of the Default Date. Such
accountants shall make such selection within thirty (30) days after such
referral. The decision of such accountants shall be final, conclusive and
binding on all parties, and shall not be subject to arbitration pursuant to
Section 6.15. All costs incurred by the non-defaulting Shareholders and the
Company in connection with obtaining the valuations referred to above shall be
borne by the Defaulting Party.

                  Section 5.14. Additional Tax Matters. (a) For so long as the
tax structure in respect of the Company and its Subsidiaries described in
Exhibit J is in effect (the "Initial Structure"), except as approved by a
Qualified Vote in accordance with Section 3.08(b), the Company shall be operated
so that neither it nor any of its Subsidiaries that is located in a tax haven
for purposes of the Mexican income tax law (Ley de Impuestos Sobre la Renta,
Titulo 1, Disposiciones Generales, Articulo 5(b) (the "Neutral Provisions") will
have any income that gives rise to any Mexican income tax payable by America
Movil or any of its Mexican Subsidiaries. In addition, for so long as the
Initial Structure is in effect, notwithstanding any other provision contained
herein, AM Latin America, on behalf of itself and America Movil may elect at any
time, in its sole discretion to cause the Company and certain of its
Subsidiaries to adopt, either the Danish Structure or the Netherlands-Danish
Structure, set forth in Exhibit J hereto (the "Alternate Structure") by
delivering the Structure Notice (as defined below) to the other Shareholders and
the Shareholders shall take all necessary actions to give effect to such
election; provided, however, if any change or modification in the tax laws of
Denmark (in the case of the Danish Structure) or Denmark or the Netherlands (in
the case of the Netherlands-Danish Structure) takes place after the date hereof
but prior to the date of the Structure Notice which would materially adversely
affect the tax position of any Veto Shareholder as a Shareholder of the Company
under the relevant Alternate Structure, the Veto Shareholders shall negotiate in
good faith to agree to a substitute tax structure, and until such agreement is
reached, no Structure Notice may be given that specifies an Alternate Structure
based in the tax jurisdiction in which such change or modification has occurred;
provided, further, that each Shareholder shall be deemed to have agreed to any
proposed substitute tax structure under which its net tax obligations are equal
to or less than the net tax obligations it would have incurred under the Danish
Structure or the Netherlands-Danish Structure absent any such change in law. For
purposes of this Section 5.14, "Structure Notice" shall mean a certificate
signed by a senior officer of AM Latin America, on behalf of itself and America
Movil, stating that implementation of the Alternate Structure specified therein
will avoid adverse tax consequences for America Movil and its Mexican
Subsidiaries. Such Alternate Structure shall be implemented within 30 days
following the date of such notice or as soon as practicable thereafter. The
costs, expenses and losses incurred by the Company or any Shareholder in
implementing such Alternate Structure shall be borne by the Company.

<PAGE>

                  (b) Notwithstanding Section 3.08(b), in the event of a
Material Tax Change (as defined below) after Consolidation, the Veto
Shareholders (other than any Affiliate of BCE) acting jointly shall have the
right to cause the Company to reorganize or redomicile in a new jurisdiction,
and the other Shareholders shall take all action necessary to cause the Company
to effect such reorganization or redomicilation. The costs, expenses and losses
incurred by the Company or any Shareholder in carrying out any such
reorganization or redomicilation shall be borne by the Company. Any change or
modification in any tax Laws (including treaties) of Canada or any political or
taxing subdivision thereof that would materially adversely affect any of SBCI or
America Movil or any of its Mexican Subsidiaries (as shareholders in a Canadian
company) or the Company (including, without limitation, any change in (i) the
effective income tax rate applicable to the Company, (ii) withholding taxes
applicable to dividends paid to SBCI, AM Latin America or America Movil or any
of its Mexican Subsidiaries, or the Company, (iii) taxes incurred upon the Sale
by SBCI or AM Latin America or America Movil or any of its Mexican Subsidiaries,
directly or indirectly, of any Equity Interests in the Company, (iv) taxes
assessed upon interest income earned by SBCI, AM Latin America or America Movil
or any of its Mexican Subsidiaries, or the Company, or (v) taxes payable by the
Company in respect of interest payments made) shall be deemed a "Material Tax
Change";

                  Section 5.15. BCE and SBCI Parent Guarantee and Share
Retention Agreement. (a) In the event that BCI owns no material assets other
than its interest in the Company, BCE shall execute a Guarantee and Share
Retention Agreement substantially in the form set forth in Exhibit D hereto,
guaranteeing the obligations of any of its Subsidiaries which are Shareholders
hereunder.

                  (b) In the event that SBCI owns no material assets other than
its interest in the Company, SBCI Parent shall execute a Guarantee and Share
Retention Agreement substantially in the form set forth in Exhibit D hereto,
guaranteeing the obligations of any of its Subsidiaries which are Shareholders
hereunder.

<PAGE>

                  Section 5.16. Subnewco4. Effective as of the date hereof and
for so long as the Exchangeable Debenture Agreement dated as of November 16,
2000 among SBCI Brazil Holding, the Company and Subnewco4 remains outstanding
(such period, the "Payment Period"), SBCI Brazil Holding hereby assigns and
sells to the Company any and all rights of SBCI Brazil Holding or any Affiliate
of SBCI Brazil Holding to receive any distribution, whether in cash or in kind
or in the form of a dividend or otherwise, in respect of the Equity Interests of
Subnewco4, and the Company hereby accepts such assignment from SBCI Brazil
Holding. Any such distribution received by SBCI Brazil Holding or any Affiliate
during the Payment Period or, if received following the Payment Period, to which
SBCI Brazil Holding or any Affiliate became entitled during the Payment Period,
shall be received and held in trust for the benefit of the Company, shall be
segregated from other property and funds, and shall forthwith be paid or
delivered to the Company in the same form so received (with any necessary
endorsement and assignment).

                  Section 5.17. Compliance with ANATEL Written Confirmation.
Each of the parties hereto shall take all necessary action to amend the terms of
this Agreement and the other Transaction Documents, as applicable, to (i) comply
with the terms of the letter to SBCI, BCI and America Movil (as successor in
interest to Telmex), dated November 10, 2000, from Sr. Amadeu de Paula Castro
Neto, Executive Superintendent of ANATEL (the "ANATEL Letter"), including,
without limitation, with respect to the issue of control by BCI over Subnewco4
and by SBCI and America Movil over Subnewco1 contained in the third paragraph of
the ANATEL Letter, and (ii) comply with the terms of that certain letter to the
Executive Superintendent of ANATEL, dated November 9, 2000, from BCI, America
Movil and SBCI concerning reducing the Company's ownership of the voting capital
of each of Subnewco1 and Subnewco4 to 19.99% within twenty (20) days following
the Closing Date. Furthermore, the parties hereto agree that, to the fullest
extent permitted by applicable Brazilian law and regulations, including, without
limitation, the terms of the ANATEL Letter, in structuring the reduction of the
Company's ownership of each of Subnewco1 and Subnewco4 as contemplated in the
ANATEL Letter, the parties will use their reasonable best efforts to transfer or
otherwise provide for the right to acquire all or a portion of the voting
capital in Subnewco1 and Subnewco4 held by the Company in excess of 19.99% to AM
Latin America or its Permitted Transferee, and will negotiate in good faith the
terms of any such transfer, including the structuring of such transfer in such a
manner as to avoid any Taxes applicable to the Company, AM Latin America or AM
Latin America's Permitted Transferee as a result of such Transfer.

                  Section 5.18. Reserve of Promissory Notes. The Company shall,
and each of the Shareholders shall cause the Company to, hold in reserve the
Promissory Notes to cover certain obligations of each of SBCI and America Movil
assumed by the Company pursuant to an Assumption Agreement, dated as of November
16, 2000, among SBCI, America Movil and the Company (the "Assumption
Agreement"), as set forth in this Section 5.18. For the period during which any
Promissory Note shall remain outstanding, the Company shall, and each of the
Shareholders shall cause the Company to, hold in reserve and not draw upon or
otherwise encumber or utilize the Promissory Notes in respect of the aggregate
principal amount of $200,000,000, comprised as follows: (i) $100,000,000 with
respect to the SBCI Assumed Obligations (as such term is defined in the
Assumption Agreement); and (ii) $100,000,000 with respect to the AM Assumed
Obligations (as such term is defined in the Assumption Agreement). The aggregate
principal amount of the Promissory Notes prior to their repayment or prepayment
as set forth above shall be held in reserve by the Company and may not be drawn
upon or otherwise encumbered or utilized by the Company without the prior
written consent of each of SBCI and America Movil until (A) all the SBCI Assumed
Obligations and AM Assumed Obligations have been paid in full and fully
discharged or (B) the Company has obtained the unconditional release of each of
SBCI and America Movil with respect to all of the SBCI Assumed Obligations and
AM Assumed Obligations covered by the Assumption Agreement.

                  Section 6.05. Severability. If any term or other provision of
this Agreement is invalid, illegal or incapable of being enforced by any Law,
governmental regulation or public policy, all other terms and provisions of this
Agreement shall nevertheless remain in full force and effect as long as the
economic or legal substance of the transactions contemplated hereby is not
affected in any manner materially adverse to any party. Upon such determination
that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as

hereby are consummated as originally contemplated to the greatest extent
possible.

                  Section 6.06. Entire Agreement. This Agreement and the
Transaction Documents constitute the entire agreement of the parties hereto with
respect to the subject matter hereof and thereof and supersede all prior

                  Section 6.07. Assignment. This Agreement may not be assigned
without the express written consent of the parties (which consent may be granted
or withheld in the sole discretion of any party), except that any Shareholder
may assign its rights hereunder as permitted by Section 3.13 and Article IV
hereof; provided, however, that any Sponsor Party may, without the written
consent of any other party, assign and delegate this Agreement and its rights
and obligations hereunder in connection with a merger, consolidation or sale of
all or substantially all of its assets.

                  Section 6.08. No Third Party Beneficiaries. This Agreement
shall be binding upon and inure solely to the benefit of the parties hereto and
their permitted assigns and successors and nothing herein, express or implied,
is intended to or shall confer upon any other person or entity, any legal or
equitable right, benefit or remedy of any nature whatsoever under or by reason
of this Agreement.

                  Section 6.09. Amendment. Subject to Section 6.17, this
Agreement may not be amended or modified, except by an instrument in writing

                  Section 6.10. Governing Law. This Agreement shall be governed
by, and construed in accordance with, the laws of the State of New York
applicable to contracts executed in and to be performed in that State without
regard to conflicts of law.

                  Section 6.11. Counterparts. This Agreement may be executed and
delivered in one or more counterparts, and by the different parties hereto in
separate counterparts, each of which when executed and shall be deemed to be an
original but all of which taken together shall constitute one and the same
agreement.

                  Section 6.12. Specific Performance. The parties hereto agree
that irreparable damage would occur in the event any provision of this Agreement

other remedy at Law or in equity.

                  Section 6.13. Waiver of Jury Trial. Each of the parties hereto

<PAGE>

                  Section 6.14. Dispute Resolution. The parties agree that any
controversy, claim or dispute arising out of or relating to or in connection
with this Agreement including, without limitation, any dispute regarding its
breach, termination, enforceability or validity hereof (each, a "Dispute")
should be regarded as a business problem to be resolved promptly through
business-oriented negotiations before resorting to arbitration pursuant to
Section 6.15. The parties therefore agree to attempt in good faith to resolve
any Dispute promptly by negotiation between the executives of the parties who
have authority to settle the Dispute. Such negotiations shall commence upon the
mailing of a notice (the "Dispute Notice") from the appropriate executive of the
requesting party to an appropriate executive of the responding party. If the
Dispute has not been resolved by these Persons within forty-five (45) days of
the date of the Dispute Notice, unless the parties agree in writing to a longer
period, the Dispute shall be referred to the chief executive officer of each of
BCI and America Movil, for discussion and negotiation among them. In the event
the Dispute has still not been resolved by negotiation within forty-five (45)
days of such referral, then such Dispute shall be settled pursuant to binding
arbitration pursuant to Section 6.15. All negotiations pursuant to this Section
6.14 shall be confidential and shall be treated as compromise and settlement
negotiations for purposes of applicable rules of evidence and shall not be used
for, or admitted in, any arbitration or court proceedings under this Agreement.

                  Section 6.15. Arbitration . (a) Any Dispute that has not been
resolved pursuant to Section 6.14 shall be finally settled by binding
arbitration in The City of New York, New York County, before a panel of three
arbitrators. The arbitration shall be administered by the International Court of
Arbitration of the International Chamber of Commerce (the "ICC") under its Rules
of Arbitration as in effect at the time of this Agreement, except as they may be
modified herein by agreement of the parties and shall be conducted in the
English language. Each party shall nominate one arbitrator, obtain its nominee's
acceptance of such nomination, and deliver written notification of such
nomination and acceptance to the other party within thirty (30) days after
delivery of the request for arbitration. In the event a party fails to nominate
an arbitrator or deliver notification of such nomination to the other party
within this time period, upon request of any party, such arbitrator shall
instead be appointed by the ICC within thirty (30) days of receiving such
request. In the event there are two Shareholders who are parties to the dispute,
the two arbitrators nominated in accordance with the above provisions shall
nominate the third arbitrator, obtain the nominee's acceptance of such
nomination and notify the parties in writing of such nomination and acceptance
within thirty days of their nomination. If the first two nominated arbitrators
fail to nominate a third arbitrator or notify the parties of that nomination
within this time period, then, upon request of either party, the third
arbitrator shall be appointed by the ICC within thirty (30) days of receiving
such request. Nonetheless, in no event shall any such arbitrator nominated by
the other arbitrators be a resident in, or a domicile of, any country in which a
shareholder is domiciled or has its principal place of business. In the event
that more than two Shareholders are parties to the Dispute, each such
Shareholder shall be entitled to nominate an arbitrator in the manner and time
period referred to above. In the event a party fails to nominate an arbitrator
or deliver notification of such nomination to the other parties within this time
period, upon request of any party, such arbitrator shall instead be appointed by
the ICC within thirty (30) days of receiving such request. The arbitrators
appointed in accordance with the previous two sentences shall mutually agree to
designate one of them to act as chair within thirty days of their appointment.
For the sake of clarity, it is expressly understood that the function of such
chair is administrative only and shall not signify that such chair has greater
or different powers as arbitrator from the other arbitrators. In the event that
the arbitrators nominated in accordance with the above provisions fail to agree
upon the selection of a chair within this time period, upon request of any
party, the chair shall instead be designated by the ICC within thirty days of
receiving such request. The award of the arbitrators shall be final and binding
upon the parties, and shall not be subject to any appeal or review. The parties
agree to submit to the non-exclusive personal jurisdiction of the federal and
state courts sitting in The City of New York, New York for the purpose of
enforcing this agreement to arbitrate.

<PAGE>

                  (b) No provision of, nor the exercise of any rights under,
this Section 6.15 shall limit the right of any party to request and obtain from
a court of competent jurisdiction in The City of New York (which shall have
exclusive jurisdiction for purposes of this Section 6.15(b)) before, during or
after the pendency of any arbitration, provisional or ancillary remedies and
relief including, but not limited to, injunctive or mandatory relief or the
appointment of a receiver. The institution and maintenance of an action or
judicial proceeding for, or pursuit of, provisional or ancillary remedies shall
not constitute a waiver of the right of any party, even if it is the plaintiff,
to submit the dispute to arbitration if such party would otherwise have such
right. Each of the parties hereby submits unconditionally (to the extent
permitted by applicable law) to the exclusive jurisdiction of the state and
federal courts located in The City of New York, County of New York for purposes
of this provision, waives objection to the venue of any proceeding in any such
court or that any such court provides an inconvenient forum and consents to the
service of process upon it in connection with any proceeding instituted under
this Section 6.15(b) in the same manner as provided for the giving of notice
hereunder.

                  (c) Judgment upon the award rendered may be entered in any
court having jurisdiction. The parties hereby expressly consent to the
nonexclusive jurisdiction of the state and federal courts situated in The City
of New York, County of New York for this purpose and waive objection to the
venue of any proceeding in such court or that such court provides an
inconvenient forum.

                  (d) Each of the parties participating in an arbitration
pursuant to the terms of this Agreement shall, subject to the award of the
arbitrators, pay an equal share of the arbitrators' fees. The arbitrators shall
have the power to award recovery of all costs (including reasonable attorneys'
fees, administrative fees, arbitrators' fees and court costs) to the prevailing
party.

                  (e) Each of:

          (i) BCI Investments, BCI and BCE hereby irrevocably designates CT
     Corporation, with offices situated at present at 111 Eighth Avenue, New
     York, New York 10011;

          (ii) SBCI Brazil Holding, SBCI and SBCI Parent hereby irrevocably
     designates CT Corporation, with offices situated at present at 111 Eighth
     Avenue, New York, New York 10011; and

          (iii) America Movil and AM Latin America hereby irrevocably designates

as its authorized agent, respectively, to accept and acknowledge on its behalf
service of any process which may be served in any proceeding in New York.

                  Section 6.16. Termination. This Agreement shall terminate with
respect to any Shareholder on the date on which such Shareholder no longer owns
any Shares; provided that any liabilities or obligations of such Shareholder
arising hereunder on or prior to such date, or based on any event or
circumstance arising on or prior to such date, shall survive termination of this
Agreement.

                  Section 6.17. Minimum Interests. Notwithstanding any provision
to the contrary set forth herein (except as set forth in Sections 3.04(a),
3.04(b) and 5.05(h)), if any Shareholder holds less than ten percent (10%) of
the total Equity Interests in the Company, such Shareholder shall have all of
the obligations, but none of the rights, of a Shareholder hereunder; provided,
that this Agreement may not be amended in any manner that materially adversely
affects such Shareholder without the written consent of such a Shareholder.

                  Section 6.18. Aggregating Interests. To the extent that any
Shareholder's rights or obligations hereunder are conditioned upon such
Shareholder maintaining ownership of a specified percentage of the Outstanding
Shares or Equity Interests in the Company, the Equity Interests owned by such
Shareholder may, without duplication, be aggregated with the Equity Interests
owned by Permitted Transferees of such Shareholder for purposes of calculating
such percentages.

Agreement to be duly executed by their respective authorized signatories

                    Transferee shall be permitted to hold Preferred Shares only
                    for so long as it continues to hold Telecom Americas Shares

     (1)  Upon the occurrence of the Redemption Condition, the Company shall
          redeem all, but not less than all, of the Preferred Shares outstanding
          at the time of such redemption. On any such redemption, the Company

     (3)  The failure of the Company to redeem the shares upon the occurrence of
          the Redemption Condition shall not constitute a waiver of the
          Company's right and obligation to redeem the Preferred Shares.

     Shares in the Company may only be issued shares as registered shares and
     may not be exchanged for shares issued to bearer.

               nominate one (1) director for election to the Board pursuant to
               clause (2) below or two (2) directors for election pursuant to
               subclause (c) below, each of BCI Investments and AM Latin America
               shall be entitled to nominate two (2) directors for election to
               the Board for so long as it holds at least twenty percent (20%)
               of the Outstanding Shares; PROVIDED THAT no such Shareholder may
               exercise such right at any time when it is a Defaulting
               Shareholder. If at any time either BCI Investments or AM Latin
               America shall hold less than twenty percent (20%) of the
               Outstanding Shares, BCI Investments or AM Latin America, as the
               case may be, shall forfeit its right to nominate two (2)
               directors for election to the Board pursuant to this subclause
               (b); PROVIDED THAT if: (A) at any time subsequent to forfeiting
               such right, either BCI Investments or AM Latin America, as the
               case may be, holds at least 20% of the Outstanding Shares, (B) at
               such time SBCI Brazil Holding has the right to nominate one (1)
               director for election to the Board pursuant to clause (2) of this
               Bye-law 12 or two (2) directors for election to the Board
               pursuant to subclause (c) below, and (C) BCI Investments or AM
               Latin America, as the case may be, has not previously transferred
               its right to nominate two (2) directors for election to the Board
               to a Veto Transferee pursuant to Bye-law 65, then BCI Investments
               or AM Latin America, as the case may be, shall regain its right
               to nominate (2) directors for election to the Board pursuant to
               this subclause (b).

          (c)  If at any time after the date hereof, SBCI Brazil Holding holds
               twenty percent (20%) or more of the Outstanding Shares (the date
               on which such interest is acquired, the "Two Director Date"), it
               shall be entitled to nominate two (2) directors for election to
               the Board for so long as it continues to hold at least twenty
               percent (20%) of the Outstanding Shares; PROVIDED THAT SBCI
               Brazil Holding may not exercise such right at any time when it is
               a Defaulting Shareholder. If at any time prior to the Two
               Director Date SBCI Brazil Holding shall hold less than ten
               percent (10%) of the Outstanding Shares, or if at any time after
               the Two Director Date SBCI Brazil Holding shall hold less than
               twenty percent (20%) of the Outstanding Shares, it shall forfeit
               its right to nominate two (2) directors for election to the Board
               pursuant to this subclause (c); PROVIDED THAT if: (A) at any time
               subsequent to forfeiting such right, SBCI Brazil Holding holds at
               least 20% of the Outstanding Shares, and (B) SBCI Brazil Holding
               has not previously transferred its right to nominate two (2)
               directors for election to the Board to a Veto Transferee pursuant
               to Bye-law 65, then SBCI Brazil Holding shall regain its right to
               nominate two (2) directors for election to the Board pursuant to
               this subclause (c).

     (2) Each of BCI Investments and AM Latin America shall be entitled
hereunder to nominate one (1) director for election to the Board for so long as
it holds at least ten percent (10%) of the Outstanding Shares; PROVIDED THAT
neither BCI Investments nor AM Latin America may exercise such right at any time
when it is a Defaulting Shareholder. If at any time such Initial Shareholder
shall hold less than ten percent (10%) of the Outstanding Shares, it shall
forfeit such right; PROVIDED THAT if: (i) at any time subsequent to forfeiting
such right, either BCI Investments or AM Latin America, as the case may be,
holds at least 10% of the Outstanding Shares of the Company, and (ii) BCI
Investments or AM Latin America, as the case may be, has not previously
transferred its right to nominate one (1) director for election to the Board to
a Director Transferee pursuant to Bye-law 66 or its right to nominate two (2) or
three (3) directors for election to the Board to a Veto Transferee pursuant to
Bye-law 65, then BCI Investments or AM Latin America, as the case may be, shall
regain its right to nominate one (1) director for election to the Board pursuant
to this clause (2). Subject to the immediately succeeding sentence, if at any
time after the date hereof, SBCI Brazil Holding increases its ownership interest
in the Company such that it holds fifteen percent (15%) or more of the
Outstanding Shares (the date on which such interest is acquired, the "One
Director Date"), SBCI Brazil Holding shall be entitled to nominate one (1)
director for election to the Board for so long as it continues to hold at least
ten percent (10%) of the Outstanding Shares; PROVIDED THAT SBCI Brazil Holding
may not exercise such right at any time when it is a Defaulting Shareholder. If
at any time SBCI Brazil Holding shall hold less than ten percent (10%) of the
Outstanding Shares, it shall forfeit its right to nominate one (1) director for
election to the Board pursuant to this clause (2); PROVIDED THAT if: (i) at any
time subsequent to forfeiting such right, SBCI Brazil Holding holds at least 10%
of the Outstanding Shares of the Company, and (ii) SBCI Brazil Holding has not
previously transferred its right to nominate one (1) director for election to
the Board to a Director Transferee pursuant to Bye-law 66 or its right to
nominate two (2) directors for election to the Board to a Veto Transferee
pursuant to Bye-law 65, then SBCI Brazil Holding shall regain its right to
nominate (1) director for election to the Board pursuant to this clause (2). The
rights granted to each Initial Shareholder pursuant to this clause (2) shall not
be effective with respect to any Initial Shareholder that has the right to
nominate two (2) or more directors for election to the Board pursuant to clause
(1) above, or that has transferred its rights under clause (1) above pursuant to
Bye-law 65.

     (3) No failure to nominate or elect a director at an annual or special
general meeting of the Company shall prevent any Shareholder from thereafter
nominating a director to fill such vacancy or shall constitute a waiver of such
party's rights under this Bye-law 12.

     (4) Except as otherwise provided in these Bye-laws, all Directors shall be
nominated by Members holding a majority of Outstanding Shares entitled to vote
generally in the election of Directors.

13.  Number of Directors

     (1) Subject to Subclause (2) below, the Board shall consist of six
directors, with three directors nominated by BCI Investments and three directors
nominated by AM Latin America. Such directors shall be elected or appointed at
the annual general meeting or at any special general meeting called for the
purpose and shall hold office for such term as the Members may determine or, in
the absence of such determination, until the next annual general meeting or
until their successors are elected or appointed, their resignation or removal in
accordance with these Bye-laws, or their office is otherwise vacated, and,
except as otherwise provided herein, any general meeting may authorise the Board
to fill any vacancy in their number left unfilled at a general meeting.

     (2) If at any time a Shareholder shall hold more than fifty percent (50%)
of the Outstanding Shares, the number of directors on the Board shall be
increased to such number as to permit such Shareholder to nominate a majority of
the directors of the Board; PROVIDED THAT any increase in the number of
directors on the Board pursuant to this clause (2) shall be effected without
detriment to the rights of Shareholders under Bye-law 12. Upon the occurrence of
the One Director Date, if the number of directors on the Board is six (6) and
there are two Veto Shareholders, the number of directors on the Board shall be
decreased to (5). Thereafter, the number of directors on the Board shall be
increased by one (1) member to a total of six (6) members if the number of Veto
Shareholders is increased to three (3).

14.  Defects in appointment of Directors

     Subject to Bye-law 60, all acts done bona fide by any meeting of the Board
or by a committee of the Board or by any person acting as a Director shall,
notwithstanding that it be afterwards discovered that there was some defect in
the appointment of any Director or person acting as aforesaid, or that they or
any of them were disqualified, be as valid as if every such person had been duly
appointed and was qualified to be a Director.

15.  Alternate Directors

     (1) Unless the Members otherwise resolve, any Director may appoint a person
or persons to act as a Director in the alternative to himself or herself by
notice in writing deposited with the Secretary. Any person so appointed shall
have all the rights and powers of the Director or Directors for whom such person
is appointed in the alternative; PROVIDED THAT such person shall not be counted
more than once in determining whether or not a quorum is present.

     (2) An Alternate Director shall be entitled to receive notice of all
meetings of the Board and to attend and vote at any such meeting at which a
Director for whom such Alternate Director was appointed in the alternative is
not personally present and generally to perform at such meeting all the
functions of such Director for whom such Alternate Director was appointed.

     (3) An Alternate Director shall cease to be such if the Director for whom
such Alternate Director was appointed ceases for any reason to be a Director.

PROVIDED THAT notice of the meeting convened for the purpose of removing a
Director shall be delivered to such Director not less than three (3) days before
the meeting and contain a statement of such intention.

     (2) In the event that (a) the percentage of Outstanding Shares held by any
Initial Shareholder is reduced from twenty percent (20%) or greater to below
twenty percent (20%) (but such percentage is equal to or exceeds ten percent
(10%) of the Outstanding Shares), and as a result such Initial Shareholder shall
forfeit its existing rights under clause 1(a) of Bye-law 12 (and its rights
under clause 1(b) of Bye-law 12 become effective), or (b) the percentage of
Outstanding Shares held by (x) BCI Investments or AM Latin America is reduced
from a percentage that is less than twenty percent (20%) but at least ten
percent (10%) to less than ten percent (10%) of the Outstanding Shares, or (y)
SBCI Brazil Holding is reduced after the One Director Date from a percentage
that is less than twenty percent (20%) but at least ten percent (10%) to less
than ten percent (10%) of the Outstanding Shares, and, in either case, as a
result such Initial Shareholder shall forfeit its existing rights under clause
(2) of Bye-law 12, upon the written request of any Shareholder, the office of
one (1) Director nominated by such Initial Shareholder (or if the case of
subclause (a) arises prior to the earlier of the One Director Date or the Two
Director Date, the offices of two (2) directors nominated by such Initial
Shareholder) and specified in such request shall be vacated in accordance with
Bye-law 17(5). Any replacement for such removed director shall be nominated and
elected as provided in Bye-law 17(3).

     (3) In the event that the percentage of Outstanding Shares held by any
Initial Shareholder is reduced from twenty percent (20%) or greater to less than
ten percent (10%) of the Outstanding Shares, and as a result such Initial
Shareholder shall forfeit its existing rights under clause (1) of Bye-law 12 and
potential rights under clause (2) of Bye-law 12, upon the written request of any
Shareholder, the offices of two (2) of the directors nominated by such Initial
Shareholder (or, prior to the occurrence of the earlier of the One Director Date
or the Two Director Date, the offices of three (3) directors nominated by such
Initial Shareholder) and specified in such request shall be vacated in
accordance with By-law 17(5). Any replacements for such removed directors shall
be nominated and elected as provided in Bye-law 17(3).

     (4) In the event that the number of directors on the Board is reduced to

of the directors nominated by each Veto Shareholder shall be vacated in
accordance with Bye-law 17(5).

     (5) For so long as any Shareholder is a Defaulting Shareholder, any other
Shareholder may request in writing the removal of the directors nominated by
such Defaulting Shareholder pursuant to Bye-law 12. Upon such request, the

replacements for such directors shall be nominated and elected as provided in
Bye-law 17(3).

17.  Vacancies on the Board

     (1) In the event that a vacancy is created on the Board at any time by
death, disability, retirement, resignation, disqualification or removal of any
director (other than removal pursuant to clauses (2), (3) or (5) of Bye-law 16),
the Shareholder that nominated such director shall have the right to nominate a
replacement director to fill such vacancy. In the event a Shareholder having the
right to nominate a replacement Director shall not have nominated a replacement
Director to fill such vacancy at the time of the next following meeting of the
Board, the other Shareholders shall have the right to nominate a Director to
serve on the Board until such Shareholder shall nominate a replacement, and such

vacancy is created on the Board at any time by the removal of any Director or
Directors pursuant to clauses (2), (3) or (5) of Bye-law 16, the determination
as to which Shareholder or Shareholders shall have the right to nominate a
replacement Director or Directors to fill such vacancy shall be made on the
basis that representation on the Board shall be proportionate to each
Shareholders' percentage holdings of the Outstanding Shares, subject to the
rights of any Shareholder under Bye-law 12.

     (4) The Board may act notwithstanding any vacancy in its number but, if and
so long as its number is reduced below the number fixed by these Bye-laws as the
quorum necessary for the transaction of business at meetings of the Board, the
continuing Directors or Director may act for the purpose of (i) summoning a
general meeting of the Company or (ii) preserving the assets of the Company.

     (5) The office of Director shall be vacated if the Director:

present at any meeting of the Board at which the transaction of business does
not require a Qualified Vote pursuant to these Bye-laws, or at which certain

Vote, then those matters not requiring a Qualified Vote shall be postponed to a
Board meeting to be held on the date that is five (5) Business Days after the

Shareholder need be present at any meeting of the Members in order to constitute
a quorum for the transaction of business at such meeting (and any Shares held by
any such Defaulting Shareholder shall not be considered "entitled to vote" for
these purposes); PROVIDED FURTHER THAT in the event any Veto Shareholder (other
than a Defaulting Shareholder) is not present at any duly called meeting of
Shareholders at which the transaction of business does not require a Qualified
Vote pursuant to these Bye-laws, or at which certain matters require a Qualified
Vote and certain matters do not require a Qualified Vote, then any matter to be
submitted to a vote of Members at such meeting that does not require a Qualified
Vote shall be postponed to a meeting of Members to be held on the date that is
five Business Days after the date on which the original meeting was to be held,
at which meeting the presence of Shareholders holding a majority of the
Outstanding Shares shall constitute a quorum for the approval of those matters
not requiring a Qualified Vote.

40.  Adjournment of meetings

     The chairman of a general meeting may, with the consent of the Members at
any general meeting at which a quorum is present (and shall if so directed),
adjourn the meeting. Unless the meeting is adjourned to a specific date and
time, fresh notice of the date, time and place for the resumption of the
adjourned meeting shall be given to each Member in accordance with the
provisions of these Bye-laws.

41.  Attendance at meetings

     Members may participate in any general meeting by means of such telephone
or video conference facilities so as to permit all persons participating in the
meeting to communicate with each other simultaneously and instantaneously, and
participation in such a meeting shall constitute presence in person at such
meeting.

42.  Written resolutions

     (1) Subject to clause (6) below, anything which may be done by resolution
of the Company in general meeting or by resolution of a meeting of any class of
the Members of the Company, may, without a meeting and without any previous
notice being required, be done by resolution in writing signed by, or, in the
case of a Member that is a corporation whether or not a company within the
meaning of the Act, on behalf of, all the Members who at the date of the
resolution would be entitled to attend the meeting and vote on the resolution.

     (2) A resolution in writing may be signed by, or, in the case of a Member
that is a corporation whether or not a company within the meaning of the Act, on
behalf of, all the Members, or any class thereof, in as many counterparts as may
be necessary.

     (3) For the purposes of this Bye-law, the date of the resolution is the
date when the resolution is signed by, or, in the case of a Member that is a
corporation whether or not a company within the meaning of the Act, on behalf
of, the last Member to sign and any reference in any Bye-law to the date of
passing of a resolution is, in relation to a resolution made in accordance with
this Bye-law, a reference to such date.

     (4) A resolution in writing made in accordance with this Bye-law is as
valid as if it had been passed by the Company in general meeting or by a meeting
of the relevant class of Members, as the case may be, and any reference in any
Bye-law to a meeting at which a resolution is passed or to Members voting in
favour of a resolution shall be construed accordingly.

     (5) A resolution in writing made in accordance with this Bye-law shall
constitute minutes for the purposes of Sections 81 and 82 of the Act.

     (6) This Bye-law shall not apply to

          (a)  a resolution passed pursuant to Section 89(5) of the Act, or

          (b)  a resolution passed for the purpose of removing a Director before
               the expiration of his term of office under these Bye-laws.

43.  Attendance of Directors

     The Directors of the Company shall, upon written request deposited at the
registered office of the Company, be entitled to receive notice of and to attend
and be heard at any general meeting.

44.  Voting at meetings

     (1) Subject to the provisions of the Act and these Bye-laws, any question
proposed for the consideration of the Members at any general meeting shall be
decided by the affirmative votes of a majority of the votes cast in accordance
with the provisions of these Bye-laws and in the case of an equality of votes
the resolution shall fail. Notwithstanding the foregoing, any action of the
Company that is required by Law to be approved by the Members or that requires a
Qualified Vote pursuant to Bye-law 11 shall require the approval of each Veto
Shareholder (other than a Defaulting Shareholder), and any of the matters set
forth in Bye-law 46 shall require the approval of each Initial Shareholder
(other than a Defaulting Shareholder) holding at least ten percent (10%) of the
Outstanding Shares.

     (2) No Member shall be entitled to vote at any general meeting unless such
Member has paid all the calls on all shares held by such Member.

     (3) Any Sale of Shares not permitted by the provisions of these Bye-laws
shall result in the loss of all voting rights of the Shares that were the
subject of such Sale, and no Member holding such Shares shall be entitled to
vote at any general meeting.

     (4) The provisions of the last sentence of Section 5.05(b) and the last
sentence of Section 5.05(e) of the Shareholders Agreement are hereby
incorporated by reference in their entirety in these Bye-laws.

45.  Voting on show of hands

     At any general meeting a resolution put to the vote of the meeting shall,
in the first instance, be voted upon by a show of hands and, subject to any
rights or restrictions for the time being lawfully attached to any class of
shares and subject to the provisions of these Bye-laws, every Member present in
Person and every person holding a valid proxy at such meeting shall be entitled
to one vote and shall cast such vote by raising his or her hand.

46. Other Matters Requiring a Special Vote

     Notwithstanding any other provision of these Bye-laws and notwithstanding
that no vote may be required, or that a lesser percentage vote may be required,
by Law or otherwise, the Company shall not take any action without the
affirmative vote of each Initial Shareholder holding at least ten percent (10%)
of the Outstanding Shares with respect to the following actions:

          (a)  a material change in the nature or scope of the business or
               corporate strategy of the Company or any Intermediate Company or
               the entering into a joint venture or similar strategic alliance
               by any thereof with any Person; and

          (b)  the winding up or dissolution of the Company or any Intermediate
               Company; the adoption of a plan of liquidation of the Company or
               any Intermediate Company; any action by the Company or any
               Intermediate Company to commence any suit, case, proceeding or
               other action (i) under any existing or future law of any
               jurisdiction relating to bankruptcy, insolvency, reorganization
               or relief of debtors seeking to have an order for relief entered
               with respect to the Company or any Intermediate Company, or
               seeking to adjudicate it a bankrupt or insolvent, or seeking
               reorganization, arrangement, adjustment, winding-up, liquidation,
               dissolution, composition or other relief with respect to the
               Company or any Intermediate Company or (ii) seeking appointment
               of a receiver, trustee, custodian or other similar official for
               the Company or any Intermediate Company, or for all or any part
               of its assets, or making a general assignment for the benefit of
               the creditors of the Company or any Intermediate Company;

     PROVIDED THAT the affirmative vote of any Initial Shareholder holding at
least ten percent (10%) of the Outstanding Shares shall not be required if such
Initial Shareholder, at the time of such vote, is a Defaulting Shareholder, and
such Initial Shareholder need not be present at a meeting of the Shareholders,
in order to achieve a quorum for a meeting to take action on any of the matters
specified in this Bye-law 46.

47.  Decision of chairman

     At any general meeting a declaration by the chairman of the meeting that a
question proposed for consideration has, on a show of hands, been carried, or
carried unanimously, or by a particular majority, or lost, and an entry to that
effect in a book containing the minutes of the proceedings of the Company shall,
subject to the provisions of these Bye-laws, be conclusive evidence of that
fact.

48.  Demand for a poll

     (1) Notwithstanding the provisions of the immediately preceding two
Bye-laws, at any general meeting of the Company, in respect of any question
proposed for the consideration of the Members (whether before or on the
declaration of the result of a show of hands as provided for in these Bye-laws),
a poll may be demanded by any of the following persons:

          (a)  the chairman of such meeting; or

          (b)  at least three Members present in Person or represented by proxy;
               or

          (c)  any Member or Members present in Person or represented by proxy
               and holding between them not less than one-tenth of the total
               voting rights of all the Members having the right to vote at such
               meeting; or

          (d)  any Member or Members present in Person or represented by proxy
               holding shares in the Company conferring the right to vote at
               such meeting, being shares on which an aggregate sum has been
               paid up equal to not less than one-tenth of the total sum paid up
               on all such shares conferring such right.

     (2) Where, in accordance with the provisions of clause (1) of this Bye-law,
a poll is demanded, subject to any rights or restrictions for the time being
lawfully attached to any class of shares, every person present at such meeting
shall have one vote for each share of which such person is the holder or for
which such person holds a proxy and such vote shall be counted in the manner set
out in clause (4) of this Bye-Law or in the case of a general meeting at which
one or more Members are present by telephone in such manner as the chairman of
the meeting may direct and the result of such poll shall be deemed to be the
resolution of the meeting at which the poll was demanded and shall replace any
previous resolution upon the same matter which has been the subject of a show of
hands.

     (3) A poll demanded in accordance with the provisions of clause (1) of this
Bye-law, for the purpose of electing a chairman of the meeting or on a question
of adjournment, shall be taken forthwith and a poll demanded on any other
question shall be taken in such manner and at such time and place as the
Chairman (or acting chairman) may direct and any business other than that upon
which a poll has been demanded may be proceeded with pending the taking of the
poll.

     (4) Where a vote is taken by poll, each person present and entitled to vote
shall be furnished with a ballot paper on which such person shall record his or
her vote in such manner as shall be determined at the meeting having regard to
the nature of the question on which the vote is taken, and each ballot paper
shall be signed or initialled or otherwise marked so as to identify the voter
and the registered holder in the case of a proxy. At the conclusion of the poll,
the ballot papers shall be examined and counted by a committee of not less than
two Members or proxy holders appointed by the chairman for the purpose and the
result of the poll shall be declared by the chairman.

49.  Seniority of joint holders voting

     In the case of joint holders the vote of the senior who tenders a vote,
whether in person or by proxy, shall be accepted to the exclusion of the votes
of the other joint holders, and for this purpose seniority shall be determined
by the order in which the names stand in the Register of Members.

50.  Instrument of proxy

     The instrument appointing a proxy shall be in writing in the form, or as
near thereto as circumstances admit, of Form "A" in the Schedule hereto, under
the hand of the appointor or of the appointor's attorney duly authorised in
writing, or if the appointor is a corporation, either under its seal, or under
the hand of a duly authorised officer or attorney. The decision of the chairman
of any general meeting as to the validity of any instrument of proxy shall be
final.

51. Representation of corporations at meetings

     A corporation which is a Member may, by written instrument, authorise such
person as it thinks fit to act as its representative at any meeting of the
Members and the person so authorised shall be entitled to exercise the same
powers on behalf of the corporation which such person represents as that
corporation could exercise if it were an individual Member. Notwithstanding the
foregoing, the chairman of the meeting may accept such assurances as he or she
thinks fit as to the right of any person to attend and vote at general meetings
on behalf of a corporation which is a Member.

                            SHARE CAPITAL AND SHARES

52. Rights of shares

     (1) Subject to any resolution of the Members to the contrary and to the
terms and conditions of Series C Shares (as hereinafter defined) and without
prejudice to any special rights previously conferred on the holders of any
existing shares or class of shares, the share capital of the Company shall
consist of 48,000 shares which, prior to June 30, 2001, shall be comprised of
two (2) classes: (a) one class of 46,309.858 common shares with a par value of
US$1.00 per share (the "Common Shares") and (b) one class of 1,690.142 preferred
shares, Series C, par value US$1.00 per share (the "Series C Shares"). From and
after June 30, 2001, the share capital of the Company shall consist of a single
class of 46,309.858 Common Shares plus such number of Common Shares into which
any Series C Shares have been converted in accordance with these Bye-laws.

     (2) The holders of Common Shares shall, subject to the provisions of these
Bye-laws:

          (a)  be entitled to one vote per share and, for so long as the Series
               C Shares are outstanding, to vote with the Series C Shares as if
               a single class in all matters including discontinuation of the
               Company to another jurisdiction, except as otherwise provided in
               these Bye-laws;

          (b)  be entitled to effect a Sale of Shares only in accordance with
               the provisions of these Bye-laws and the Shareholders Agreement;

          (c)  be entitled to the rights set forth in Bye-law 61;

          (d)  be entitled to such dividends as the Board may from time to time
               declare;

          (e)  in the event of a winding-up or dissolution of the Company,
               whether voluntary or involuntary or for the purposes of
               reorganization or otherwise or upon any distribution of capital,
               be entitled to the surplus assets of the Company; and

          (f)  generally be entitled to enjoy all of the rights attaching to
               shares.

     (3) The holders of Series C Shares shall, subject to the provisions of
these Bye-laws, have the following rights:

          (a)  Voting Rights. Each Series C Share entitles the holder to one (1)
               vote at all meetings of the Members of the Company (except
               meetings at which only holders of another specified class of
               shares are entitled to vote pursuant to these bye-laws).

          (b)  Subject to clauses (d), (f) and (g) below, the holders of the
               Series C Shares are entitled to receive, as and when declared by
               the Board, non-cumulative dividends at a fixed rate of 0.5
               percent per month calculated on the Series C Amount of each such
               share. These dividends are payable in money, property or by the
               issue of fully paid shares of any class of the share capital of
               the Company, at the option of the Company. The holders of the
               Series C Shares are not entitled to any dividend in excess of
               these dividends. These dividends are payable always in preference
               and priority to any payment of dividends on the common shares or
               any other shares ranking junior to the Series C Shares.

          (c)  Liquidation, Dissolution and Winding-up. This provision applies
               in the event of the voluntary or involuntary liquidation,
               dissolution or winding-up of the Company or other distribution of
               assets of the Company among Members for the purpose of winding-up
               its affairs. In this event, subject to clauses (d), (f) and (g)
               below, the holders of the Series C Shares are entitled to receive
               for each Series C Share an amount equal to the Series C Amount
               plus all declared and unpaid dividends on each such Series C
               Share. The holders are not entitled to share any further in the
               distribution of the property or assets of the Company. This
               distribution is payable in preference and priority to any
               distribution of the property or assets of the Company to the
               holders of the Common Shares or any other shares ranking junior
               to the Series C Shares.

          (d)  Redemption. A holder of Series C Shares shall be entitled to
               redeem all or any part of the Series C Shares registered in the
               name of such holder on any date (a "Redemption Date") which is
               June 30, 2001, or which is any prior date on which the holder
               proposes to make a payment in whole or in part of the principal
               amount of the Redeemable and Exchangeable Promissory Note, Series
               B issued by BCI Investments on November 16, 2000, with a
               principal amount of USD$275,000,000 (the "Special Note, Series
               B"); PROVIDED THAT a holder shall have no such redemption rights
               under this clause (d) and the Company shall not be required to
               redeem any Series C Shares (i) if the principal amount of the
               Special Note, Series B has been paid in full or (ii) to the
               extent that the number of Series C Shares sought to be redeemed
               on a particular Redemption Date multiplied by the Redemption
               Price Per Share is greater than the outstanding principal amount
               of the Special Note, Series B as of that Redemption Date. The
               holder will exercise this right by delivering to the Company at
               its registered office, on or before noon Bermuda time on a
               Redemption Date, the share certificates representing the Series C
               Shares to be redeemed along with a notice specifying the number
               of Series C Shares that the registered holder desires to have
               redeemed by the Company on that Redemption Date. Upon receipt of
               such a notice, the Company shall redeem the Series C Shares
               specified in such notice, with effect as of noon Bermuda time on
               that Redemption Date, by at its option either (i) paying cash in
               the amount of USD$162,708.222149 per share (the "Redemption Price
               Per Share") or (ii)  canceling an equal
               amount of indebtedness of the holder under the Special Note,
               Series C. Notwithstanding the above, the Company will only be
               obliged to redeem Series C Shares so tendered for redemption on a
               particular Redemption Date to the extent that this redemption
               would not be contrary to any applicable law, and if the
               redemption of any such Series C Shares would be contrary to any
               applicable law, the Company will only be obliged to redeem such
               Series C Shares to the extent that moneys applied to the
               redemption will be an amount (rounded to the next lower multiple
               of one hundred United States dollars (USD$100.00)) that it would
               not be contrary to such law for the Company to pay. In this case
               the Company will pay to each holder his pro rata share of the
               allocable redemption proceeds. If less than all of the Series C
               Shares represented by any certificate are redeemed on a
               particular Redemption Date, a new certificate for the balance
               will be issued to the holder by the Company.

          (e)  Series C Amount. For the purposes of the above paragraph (c), the
               "Series C Amount" of each Series C Share will be an amount equal
               to the aggregate of, if the Series C Share was issued for money
               or a promissory note, the monetary consideration received by the
               Company, including for these purposes the amount of any
               promissory note received by the Company, upon the issuance of the
               Series C Share (denominated in the currency in which the
               consideration was received by the Company) or, if the Series C
               Share was issued for a consideration other than money or a
               promissory note, the fair market value of the consideration
               received by the Company (including, without limitation, shares of
               another class of the Company) upon the issuance of the Series C
               Share, in each case less (iii) all amounts paid in respect of the
               Series C Share on account of reductions of stated capital.

          (f)  Optional Conversion. Subject to clause (g) below, a holder of
               Series C Shares will be entitled to convert into Common Shares at
               any time all, or from time to time any part, of the Series C
               Shares registered in the name of the holder, at a ratio of one
               Common Share for each Series C Share so converted. The holder
               will exercise this right by tendering to the Company at its
               registered office the share certificate(s) representing the
               Series C Share(s) that the registered holder desires to have so
               converted together with a notice in writing, a copy of which
               shall be sent to the other holders of Common Shares, specifying
               (i) the number of Series C Shares that the registered holder
               desires to have so converted and (ii) the Business Day (in this
               paragraph referred to as the "Series C Conversion Date") on which
               the holder desires to have such Series C Shares so converted.
               Upon receipt by the Company of the share certificate(s)
               representing such Series C Share(s) together with this notice,
               each Series C Share specified in this notice will on the Series C
               Conversion Date automatically be converted into, and shall
               thereupon become, one validly issued and outstanding, fully-paid
               Common Share. From and after this date the Series C Shares
               tendered to the Company cease to be entitled to dividends and
               their holders are not entitled to exercise any of the rights of
               the holders of Series C Shares. If less than all of the Series C
               Shares represented by any certificate are converted, a new
               certificate for the balance will be issued.

          (g)  Mandatory Conversion. As of 5:00 p.m. in Bermuda on June 30,
               2001, each issued and outstanding Series C Share shall
               automatically be converted into, and shall thereupon become, one
               validly issued and outstanding, fully-paid Common Share, and the
               Company shall on that date issue to each registered holder of the
               Series C Shares a certificate representing the Common Shares into
               which the Series C Shares held by such registered holder are so
               converted, and the holders of the Series C Shares shall
               immediately tender the certificates representing all of the
               outstanding Series C Shares to the Company From and after 5:00
               p.m. in Bermuda on June 30, 2001 the Series C Shares shall cease
               to be entitled to dividends or any other distribution and their
               holders are not entitled to exercise any of the rights of the
               holders of Series C Shares.

          (h)  Amendments. No change to any of the provisions of clauses (a) to
               (g) or of this Bye-law 52(3) will have any force or effect until
               it has been approved by either (i) a majority of not less than
               two-thirds (2/3) of the votes cast by the holders of the Series C
               Shares, voting separately as a class at a meeting of such holders
               specially called for that purpose, or (ii) a resolution in
               writing signed by all the holders of the Series C Shares. This
               approval is in addition to any other approval required by the
               Act.

          (i)  No rights after cancellation or conversion. In the event of any
               redemption by the Company or at the option of the holder or any
               redemption or purchase by the Company or conversion or any other
               event which would result in the cancellation of the Series C
               Shares, the holder of the Series C Shares shall cease to have any
               rights or preferences in the Series C Shares.

53.  Power to issue shares

     (1) Subject to these Bye-laws, including without limitation Bye-law 11, and
to any resolution of the Members to the contrary, and without prejudice to any
special rights previously conferred on the holders of any existing shares or
class of shares, the Board shall have power to issue any unissued shares of the
Company on such terms and conditions as it may determine and any shares or class
of shares may be issued with such preferred, deferred or other special rights or
such restrictions, whether in regard to dividend, voting, return of capital or
otherwise as the Company may from time to time by resolution of the Members
prescribe.

     (2) The Board shall, in connection with the issue of any share, have the
power to pay such commission and brokerage as may be permitted by law.

     (3) The Company shall not give, whether directly or indirectly, whether by
means of loan, guarantee, provision of security or otherwise, any financial
assistance for the purpose of a purchase or subscription made or to be made by
any person of or for any shares in the Company, but nothing in this Bye-Law
shall prohibit transactions mentioned in Sections 39A, 39B and 39C of the Act.

     (4) Subject to Bye-law 11, the Company may from time to time do any one or
more of the following things:

          (a)  make arrangements on the issue of shares for a difference between
               the Members in the amounts and times of payments of calls on
               their shares;

          (b)  accept from any Member the whole or a part of the amount
               remaining unpaid on any shares held by him, although no part of
               that amount has been called up;

          (c)  pay dividends in proportion to the amount paid up on each share
               where a larger amount is paid up on some shares than on others;
               and

          (d)  issue its shares in fractional denominations and deal with such
               fractions to the same extent as its whole shares and shares in
               fractional denominations shall have in proportion to the
               respective fractions represented thereby all of the rights of
               whole shares including (but without limiting the generality of
               the foregoing) the right to vote, to receive dividends and
               distributions and to participate in a winding up.

54.  Variation of rights, alteration of share capital and purchase of shares of
the Company

     (1) Subject to Bye-law 11 and, for the avoidance of doubt, Bye-law 54(2),
and subject to the provisions of Sections 42 and 43 of the Act, any preference
shares may be issued or converted into shares that, at a determinable date or at
the option of the Company, are liable to be redeemed on such terms and in such
manner as the Company before the issue or conversion may by resolution of the
Members determine.

     (2) If at any time the share capital is divided into different classes of
shares, the rights attached to any class (unless otherwise provided by the terms
of issue of the shares of that class) may, whether or not the Company is being
wound-up, be varied with the consent in writing of the holders of three-fourths
of the issued shares of that class or with the sanction of a resolution passed
by a majority of the votes cast at a separate general meeting of the holders of
the shares of the class in accordance with Section 47(7) of the Act. The rights
conferred upon the holders of the shares of any class issued with preferred or
other rights shall not, unless otherwise expressly provided by the terms of
issue of the shares of that class, be deemed to be varied by the creation or
issue of further shares ranking pari passu therewith.

     (3) Subject to Bye-law 11, the Company may from time to time by resolution
of the Members change the currency denomination of, increase, alter or reduce
its share capital in accordance with the provisions of Sections 45 and 46 of the
Act. Where, on any alteration of share capital, fractions of shares or some
other difficulty would arise, the Board may deal with or resolve the same in
such manner as it thinks fit including, without limiting the generality of the
foregoing, the issue to Members, as appropriate, of fractions of shares and/or
arranging for the sale or transfer of the fractions of shares of Members.

     (4) The Company may from time to time purchase its own shares in accordance
with the provisions of Section 42A of the Act; PROVIDED, HOWEVER, that any such
purchase shall be pro rata based on the percentage of Outstanding Shares held by
each Member.

55. Registered holder of shares

     (1) The Company shall be entitled to treat the registered holder of any
share as the absolute owner thereof and accordingly shall not be bound to
recognise any equitable or other claim to, or interest in, such share on the
part of any other person.

     (2) Any dividend, interest or other moneys payable in cash in respect of
shares may be paid by cheque or draft sent through the post directed to the
Member at such Member's address in the Register of Members or, in the case of
joint holders, to such address of the holder first named in the Register of
Members, or to such person and to such address as the holder or joint holders
may in writing direct. If two or more persons are registered as joint holders of
any shares, any one can give an effectual receipt for any dividend paid in
respect of such shares, unless the Company is otherwise notified in writing by
any of such joint holders prior to the payment of such dividend.

56.  Death of a joint holder

     Where two or more persons are registered as joint holders of a share or
shares then in the event of the death of any joint holder or holders the
remaining joint holder or holders shall be absolutely entitled to the said share
or shares and the Company shall recognise no claim in respect of the estate of
any joint holder except in the case of the last survivor of such joint holders.

57.  Share certificates

     (1) Every Member shall be entitled to a certificate under the seal of the
Company (or a facsimile thereof) specifying the number and, where appropriate,
the class of shares held by such Member and whether the same are fully paid up
and, if not, how much has been paid thereon. The Board may by resolution
determine, either generally or in a particular case, that any or all signatures
on certificates may be printed thereon or affixed by mechanical means.

     (2) The Company shall be under no obligation to complete and deliver a
share certificate unless specifically called upon to do so by the person to whom
such shares have been allotted.

     (3) If any such certificate shall be proved to the satisfaction of the
Board to have been worn out, lost, mislaid or destroyed the Board may cause a
new certificate to be issued and request an indemnity for the lost certificate
if it sees fit.

58.  Calls on shares

     (1) Subject to clause (r) of Bye-law 11, the Board may from time to time
make such calls as it thinks fit upon the Members in respect of any monies
unpaid on the shares allotted to or held by such Members and, if a call is not
paid on or before the day appointed for payment thereof, the Member may at the
discretion of the Board be liable to pay the Company interest on the amount of
such call at such rate as the Board may determine, from the date when such call
was payable up to the actual date of payment. The joint holders of a share shall
be jointly and severally liable to pay all calls in respect thereof.

     (2) Subject to clause (r) of Bye-law 11, the Board may, on the issue of
shares, differentiate between the holders as to the amount of calls to be paid
and the times of payment of such calls.

59. Forfeiture of shares

     (1) Without limiting any rights of the Company under Bye-law 60, if any
Member fails to pay, on the day appointed for payment thereof, any call in
respect of any share allotted to or held by such Member, the Board may, at any
time thereafter during such time as the call remains unpaid, direct the
Secretary to forward to such Member a notice in the form, or as near thereto as
circumstances admit, of Form "B" in the Schedule hereto.

     (2) If the requirements of such notice are not complied with, any such
share may at any time thereafter before the payment of such call and the
interest due in respect thereof be forfeited by a resolution of the Board to
that effect, and such share shall thereupon become the property of the Company
and may be disposed of as the Board shall determine.

     (3) A Member whose share or shares have been forfeited as aforesaid shall,
notwithstanding such forfeiture, be liable to pay to the Company all calls owing
on such share or shares at the time of the forfeiture and all interest due
thereon.

60.  Defaulting Shareholders

     (1) If any Shareholder (a "Defaulting Party") fails to make payment with
respect to or perform any Outstanding Obligation or any share issuance approved
in accordance with these Bye-laws and in respect of which such Shareholder has
agreed to subscribe pursuant to Bye-law 61 within ten (10) Business Days of the
date due (the "Due Date"), interest shall accrue on any unpaid amount or, in the
case of AM Latin America's Outstanding Obligation to contribute the Techtel
Amount (as defined in the Joint Venture Agreement) to the Company pursuant to
Section 2.03(c) of the Joint Venture Agreement, on the value attributed to such
obligation (the "Default Amount") at a rate per annum of 200%, or, if lower, the
maximum rate permitted by applicable law (the "Default Rate") from the Due Date
until the date paid in full together with all interest accrued thereon (based on
the actual number of days elapsed over a 360-day year).

     (2) Any Shareholder (an "Advancing Party") may upon written notice to the
other Shareholders and the Company, advance all or a portion of the Default
Amount in lieu of the Defaulting Party. If more than one Shareholder provides
such a notice, such Shareholders shall have the right to fund their pro rata
portion of the Default Amount, based on the percentage of Outstanding Shares
held by such Shareholders, or such other portion as may be agreed by such
Shareholders. In the event that any Shareholder advances all or a portion of the
Default Amount in lieu of a Defaulting Party, the obligation of the Defaulting
Party to make payment to the Company of the Default Amount, together with
accrued interest, shall be deemed assigned to the Advancing Party or Parties in
proportion to the percentage of the Default Amount advanced by such Advancing
Party.

     (3) In the event that the Defaulting Party has not made payment in full of
the Default Amount, together with all accrued interest, or performed its
Outstanding Obligations and paid all accrued interest owed thereunder, to the
Company or the Advancing Parties, as appropriate, within one hundred eighty
(180) days after the Due Date, the Company shall issue new Shares to the
Advancing Parties and, in the case of a default by a Defaulting Shareholder
under its Promissory Note, or, if applicable, its Special Notes, purchase, for a
total amount of US$1.00, an equal number of Shares previously issued to the
Defaulting Party in amounts sufficient to dilute the Equity Interests of the
Defaulting Party in the Company, and reflecting (i) any advances made by
Advancing Parties, (ii) amounts paid by other Shareholders pursuant to the
Outstanding Obligations or share issuance, as the case may be, (iii) all
interest accrued on the Default Amount pursuant to clause (1) of this Bye-law
60, (iv) the fair market value of the Company at the Due Date, as determined in
accordance with clause (4) below, and (v) Equity Interests, if any, issued to
the other Shareholders at the time of such payment. The consideration for such
repurchase shall be the release of the Defaulting Shareholder from its
obligations under the Promissory Note to repay the Default Amount. All
Shareholders will be deemed to have consented to such issuance of Shares. For
the purpose of effecting a purchase of Shares in accordance with this subclause
(c), each Shareholder hereby irrevocably appoints the Company to be its
attorney, and in its name and on its behalf to do all acts and things, execute
any document or complete any transfer that the Company may require in order to
complete such purchase, and each Shareholder hereby agrees to ratify and confirm
any act of the Company in connection therewith. Notwithstanding any such
issuance of Shares, all interest accrued on the Default Amount pursuant to
clause (1) of this Bye-law 60 at the time of such issuance (the "Default
Interest Amount") shall be deemed due and owing by the Defaulting Shareholder to
the Company and interest shall accrue on the Default Interest Amount at the
Default Rate until the Default Interest Amount, together with all interest
accrued thereon, is paid in full.

     (4) For purposes of the preceding clause (3), the fair market value of the
Company shall be determined in accordance with the following procedure. Within
ten (10) Business Days following the 180-day period referred to in clause (3)
above, the Defaulting Party shall select one of the investment banks listed in
Schedule 5.13 to the Shareholders Agreement, and the Company shall select one of
the investment banks listed in such Schedule 5.13. In the event that none of the
investment banks listed in Schedule 5.13 to the Shareholders Agreement accepts
an engagement from the Defaulting Party or the Company, as the case may be
(through no fault of the Defaulting Party or the Company, as the case may be)
and there are no other investment banks listed in such Schedule 5.13 from whom
such party may choose and which are prepared to accept selection or referral, as
the case may be, the Defaulting Party or the Company, as the case may be, shall
choose an investment banking firm of international standing in the United States
which does not, and whose directors, officers, employees or Affiliates do not,
have a direct or indirect material financial interest for its proprietary
account in the Defaulting Party or the Company, as the case may be, or any of
their respective Affiliates. Within thirty (30) days of its acceptance of such
selection, each selected investment bank shall determine independently the fair
market value of the Company and provide such valuation in writing to each of the
Shareholders and the Company. If the difference between such two valuations is
twenty percent (20%) or less, the fair market value of the Company shall be
deemed to be the average of such two valuations. If the difference between such
two valuations is greater than twenty percent (20%), and if the Defaulting Party
and the Company are otherwise unable to agree which valuation is correct, within
270 days after the Default Date the matter shall be referred by the Company to
the Company's accountants, which accountants shall select one of the two
valuations as being closest to the fair market value of the Company as of the
Default Date. Such accountants shall make such selection within thirty (30) days
after such referral. The decision of such accountants shall be final, conclusive
and binding on all parties, and shall not be subject to arbitration. All costs
incurred by the non-defaulting Shareholders and the Company in connection with
obtaining the valuations referred to above shall be borne by the Defaulting
Party.

61.  Certain Issuances of New Securities

     (1) If the Company proposes to issue New Securities, other than pursuant to
a bonus issue, an initial public offering or other pro rata distribution to
Shareholders, the Shareholders shall have the right to purchase, in accordance
with clause (2) below, New Securities which the Company proposes to issue pro
rata, based on each Shareholder's Equity Interests in the Company.

     (2) In the event that the Company proposes to issue New Securities, subject
to clause (1) above, the Company shall give each Shareholder a written notice (a
"Notice of Issuance") of its intention, describing all material terms of the New
Securities and the price and all material terms upon which the Company proposes
to issue such New Securities. Each Shareholder shall have ten (10) Business Days
from the date of the Notice of Issuance to agree to purchase all or any portion
of its pro rata share of such New Securities; PROVIDED THAT if the Company is
proposing to issue New Securities for consideration other than all cash, the
Company shall accept from the Shareholders either non-cash consideration that is
reasonably comparable to the non-cash consideration specified in the Notice of
Issuance or cash in an amount equal to the fair market value of the non-cash
consideration which shall be specified in the applicable Notice of Issuance. Any
purchase by any Shareholder of New Securities shall be consummated on the date
on which all other New Securities described in the applicable Notice of Issuance
are issued.

                               REGISTER OF MEMBERS

62.  Contents of Register of Members

     The Board shall cause to be kept in one or more books a Register of Members
and shall enter therein the particulars required by the Act.

63.  Inspection of Register of Members

     The Register of Members shall be open to inspection at the registered
office of the Company on every business day, subject to such reasonable
restrictions as the Board may impose, so that not less than two hours in each
business day be allowed for inspection. The Register of Members may, after
notice has been given by advertisement in an appointed newspaper to that effect,
be closed for any time or times not exceeding in the whole thirty days in each
year.

64.  Determination of record dates

     Notwithstanding any other provision of these Bye-laws, the Board may fix
any date as the record date for:

          (a)  determining the Members entitled to receive any dividend; and

          (b)  determining the Members entitled to receive notice of and to vote
               at any general meeting of the Company.

                          TRANSFER OF GOVERNANCE RIGHTS

65.  Transfer of Certain Veto Rights

     In connection with the transfer by an Initial Shareholder to any one Person
of twenty percent (20%) or more of the Outstanding Shares in one or more
transactions in accordance with these Bye-laws, such Initial Shareholder by
prior written notice to the Company and all Shareholders, and upon transfer of
such twenty percent (20%) interest, may transfer its existing right (if any) to
nominate three (3) directors or, as the case may be, two (2) directors, to the
Board as provided in clause (1) of Bye-law 12 to such Person (the "Veto
Transferee"); PROVIDED THAT the right of an Initial Shareholder to regain the
right to nominate three (3) directors or, as the case may be, two (2) directors,
to the Board following a forfeiture of such right pursuant to clause (1) of
Bye-law 12 shall not be transferable, and any purported transfer of such right
to any Person shall be null and void. In the event such Initial Shareholder
validly transfers its transferable rights under clause (1) of Bye-law 12, such
rights may be subsequently transferred by any Veto Transferee, subject to the
restrictions applicable to an Initial Shareholder under this Bye-law 65. On
transferring such right, the transferring Initial Shareholder shall no longer
have any rights it may have enjoyed under clause (2) of Bye-law 12 and, for the
avoidance of doubt, clause (1) of Bye-law 12. Veto Transferees shall enjoy the
rights, subject to the obligations of a Veto Shareholder under these Bye-laws
and shall otherwise be subject to the obligations of a Shareholder under Section
4.06 of the Shareholders Agreement; PROVIDED THAT the rights of the transferring
Initial Shareholder under Bye-law 12 may not be transferred to a Person listed
in Schedule 3.13 to the Shareholders Agreement (or to any Affiliate or successor
of any such Person) without the prior written consent of each Veto Shareholder.
For the avoidance of doubt, in no event shall there ever be more than two (2)
Veto Shareholders, except if SBCI Brazil Holding becomes a Veto Shareholder, in
which case there shall never be more than three (3) Veto Shareholders.

66.  Transfer of Rights to Nominate Directors

     In connection with the transfer (x) by BCI Investments or AM Latin America
at any time, or (y) by SBCI Brazil Holding after the earlier to occur of the One
Director Date or the Two Director Date, to any one Person of less than twenty
percent (20%) but more than ten percent (10%) of the Outstanding Shares in one
or more transactions in accordance with these Bye-laws, such Initial Shareholder
by prior written notice to the Company and all Shareholders, and upon transfer
of such interest, may transfer to such Person (the "Director Transferee") its
existing right (if any) to nominate one director to the Board set forth in
clause (2) of Bye-law 12; PROVIDED THAT the right of an Initial Shareholder to
regain the right to nominate one (1) director to the Board following a
forfeiture of such right pursuant to clause (2) of Bye-law 12 shall not be
transferable, and any purported transfer of such right to any Person shall be
null and void. On transferring such right, the transferring Initial Shareholder
(and any subsequent transferring Director Transferee) shall no longer have any
rights it may have enjoyed under clause (2) of Bye-law 12 and, for the avoidance
of doubt, clause (1) of Bye-law 12. In the event such Initial Shareholder
validly transfers its transferable rights under clause (2) of Bye-law 12, such
rights, in addition to all rights as a Shareholder, may be subsequently
transferred by any subsequent Director Transferee, subject to the restrictions
applicable to an Initial Shareholder under this Bye-law 66. The Director
Transferee shall enjoy the rights, subject to the obligations, of the
transferring Initial Shareholder under clause (2) of Bye-law 12 and Bye-laws 16,
17, 46 and 66, and shall otherwise be subject to the obligations of a
Shareholder under Section 4.06 of the Shareholders Agreement; PROVIDED THAT the
rights of the transferring Initial Shareholder under Bye-law 46 may not be
transferred to a Person listed in Schedule 3.13 to the Shareholders Agreement
(or to any Affiliate or successor of any such Person) without the prior written
consent of each Veto Shareholder.

                               TRANSFER OF SHARES

67.  Instrument of transfer

     (1) An instrument of transfer shall be in the form or as near thereto as
circumstances admit of Form "C" in the Schedule hereto or in such other common
form as the Board may accept. Such instrument of transfer shall be signed by or
on behalf of the transferor and transferee; PROVIDED THAT, in the case of a
fully paid share, the Board may accept the instrument signed by or on behalf of
the transferor alone. The transferor shall be deemed to remain the holder of
such share until the same has been transferred to the transferee in the Register
of Members.

     (2) The Board may refuse to recognise any instrument of transfer unless it
is accompanied by the certificate in respect of the shares to which it relates
and by such other evidence as the Board may reasonably require to show the right
of the transferor to make the transfer.

68.  Restriction on transfer

     (1) The Board shall refuse to register a transfer unless all applicable
consents, authorisations and permissions of any governmental body or agency in
Bermuda have been obtained. The Board also shall refuse to register a transfer
not in compliance with the provisions of these Bye-laws or the Shareholders
Agreement.

     (2) If the Board refuses to register a transfer of any share the Secretary
shall, within three months after the date on which the transfer was lodged with
the Company, send to the transferor and transferee notice of the refusal.

     (3) The provisions of Article IV of the Shareholders Agreement are hereby
incorporated in their entirety into these Bye-laws.

69.  Transfers by joint holders

     The joint holders of any share or shares may transfer such share or shares
to one or more of such joint holders, and the surviving holder or holders of any
share or shares previously held by them jointly with a deceased Member may
transfer any such share to the executors or administrators of such deceased
Member.

                             TRANSMISSION OF SHARES

70.  Representative of deceased Member

     In the case of the death of a Member, the survivor or survivors where the
deceased Member was a joint holder, and the legal personal representatives of
the deceased Member where the deceased Member was a sole holder, shall be the
only persons recognised by the Company as having any title to the deceased
Member's interest in the shares. Nothing herein contained shall release the
estate of a deceased joint holder from any liability in respect of any share
which had been jointly held by such deceased Member with other persons. Subject
to the provisions of Section 52 of the Act, for the purpose of this Bye-law,
legal personal representative means the executor or administrator of a deceased
Member or such other person as the Board may in its absolute discretion decide
as being properly authorised to deal with the shares of a deceased Member.

71.  Registration on death or bankruptcy

     Any person becoming entitled to a share in consequence of the death or
bankruptcy of any Member may be registered as a Member upon such evidence as the
Board may deem sufficient or may elect to nominate some person to be registered
as a transferee of such share, and in such case the person becoming entitled
shall execute in favour of such nominee an instrument of transfer in the form,
or as near thereto as circumstances admit, of Form "D" in the Schedule hereto.
On the presentation thereof to the Board, accompanied by such evidence as the
Board may require to prove the title of the transferor, the transferee shall be
registered as a Member but the Board shall, in either case, have the same right
to decline or suspend registration as it would have had in the case of a
transfer of the share by that Member before such Member's death or bankruptcy,
as the case may be.

                        DIVIDENDS AND OTHER DISTRIBUTIONS

72.  Declaration of dividends by the Board

     The Board may, subject to these Bye-laws (including, without limitation,
Bye-law 11), and in accordance with Section 54 of the Act, declare a dividend to
be paid to the Members, in proportion to the number of shares held by them, and
such dividend may be paid in cash or wholly or partly in specie in which case
the Board may fix the value for distribution in specie of any assets.

73.  Other distributions

     Subject to these Bye-laws (including, without limitation, Bye-law 11), the
Board may declare and make such other distributions (in cash or in specie) to
the Members as may be lawfully made out of the assets of the Company.

74.  Reserve fund

     The Board may from time to time before declaring a dividend set aside, out
of the surplus or profits of the Company, such sum as it thinks proper as a
reserve fund to be used to meet contingencies or for equalising dividends or for
any other special purpose.

75.  Deduction of Amounts due to the Company

     The Board may deduct from the dividends or distributions payable to any
Member all monies due from such Member to the Company on account of calls or
otherwise.

                                 CAPITALISATION

76.  Issue of bonus shares

     (1) The Board may resolve to capitalize any part of the amount for the time
being standing to the credit of any of the Company's share premium or other
reserve accounts or to the credit of the profit and loss account or otherwise
available for distribution by applying such sum in paying up unissued shares to
be allotted as fully paid bonus shares pro rata to the Members.

     (2) The Company may capitalize any sum standing to the credit of a reserve
account or sums otherwise available for dividend or distribution by applying
such amounts in paying up in full partly paid shares of those Members who would
have been entitled to such sums if they were distributed by way of dividend or
distribution.

                        ACCOUNTS AND FINANCIAL STATEMENTS

77.  Records of account

     The Board shall cause to be kept proper records of account with respect to
all transactions of the Company and in particular with respect to:-

          (a)  all sums of money received and expended by the Company and the
               matters in respect of which the receipt and expenditure relates;

          (b)  all sales and purchases of goods by the Company; and

          (c)  the assets and liabilities of the Company.

     Such records of account shall be kept at the registered office of the
Company or, subject to Section 83 (2) of the Act, at such other place as the
Board thinks fit and shall be available for inspection by the Directors during
normal business hours.

78.  Financial year end

     The financial year end of the Company may be determined by resolution of
the Board and failing such resolution shall be 31st December in each year.

79.  Financial statements

     Subject to any rights to waive laying of accounts pursuant to Section 88 of
the Act, financial statements as required by the Act shall be laid before the
Members within sixty (60) days of the end of each fiscal year. In addition to
the foregoing, the Company shall prepare and deliver to each Member (i) monthly
Interim Financial Statements for each fiscal month within thirty (30) days of
the end of each fiscal month and (ii) quarterly Interim Financial Statements for
each fiscal quarter within forty-five (45) days of the end of each fiscal
quarter.

                                      AUDIT

80.  Appointment of Auditor

     Subject to Section 88 of the Act, at the annual general meeting or at a
subsequent special general meeting in each year, an independent representative
of the Members shall be appointed by them as Auditor of the accounts of the
Company. Such Auditor may be a Member but no Director, Officer or employee of
the Company shall, during his or her continuance in office, be eligible to act
as an Auditor of the Company.

81.  Remuneration of Auditor

     The remuneration of the Auditor shall be fixed by the Company in general
meeting or in such manner as the Members may determine.

82.  Vacation of office of Auditor

         (1) Subject to Bye-laws 9 and 50 and, for the avoidance of doubt,
Bye-law 51(2), and subject to the provisions of Sections 42 and 43 of the Act,
any preference shares may be issued or converted into shares that, at a
determinable date or at the option of the Company, are liable to be redeemed on
such terms and in such manner as the Company before the issue or conversion may
by resolution of the Members determine.

         (2) If at any time there are different classes of shares outstanding,
the rights attached to any class (unless otherwise provided by the terms of
issue of the shares of that class) may, in addition to any vote of the Members
or the Board otherwise required for the taking of such action, whether or not
the Company is being wound-up, be varied with the consent in writing of the
holders of three-fourths of the issued shares of that class or with the sanction
of a resolution passed by a majority of the votes cast at a separate general
meeting of the holders of the shares of the class in accordance with Section 47
(7) of the Act. The rights conferred upon the holders of the shares of any class
issued with preferred or other rights shall not, unless otherwise expressly
provided by the terms of issue of the shares of that class, be deemed to be
varied by the creation or issue of further shares ranking pari passu therewith.

         (3) The Company may from time to time by resolution of the Members
change the currency denomination of, increase, alter or reduce its share capital
in accordance with the provisions of Sections 45 and 46 of the Act and subject
to Bye-laws 9 and 50 hereof. Where, on any alteration of share capital,
fractions of shares or some other difficulty would arise, the Board may deal
with or resolve the same in such manner as it thinks fit including, without
limiting the generality of the foregoing, the issue to Members, as appropriate,
of fractions of shares and/or arranging for the sale or transfer of the
fractions of shares of Members.

         (4) Except for the redemption of the Preference Shares pursuant to
Bye-law 49 hereof, the Company may not purchase all or any part of its own
shares for so long as the Preference Shares possess voting rights, PROVIDED THAT
at such time as the Preference Shares cease to have any voting rights, the
Company may from time to time purchase its own shares in accordance with the
provisions of Section 42A of the Act.

52.  Registered holder of shares

         (1) The Company shall be entitled to treat the registered holder of any
share as the absolute owner thereof and accordingly shall not be bound to
recognise any equitable or other claim to, or interest in, such share on the
part of any other person.

         (2) Any dividend, interest or other moneys payable in cash in respect
of shares may be paid by cheque or draft sent through the post directed to the
Member at such Member's address in the Register of Members or, in the case of
joint holders, to such person and to such address as the holder or joint holders
may in writing direct. If two or more persons are registered as joint holders of
any shares any one can give an effectual receipt for any dividend paid in
respect of such shares.

53.  Death of a joint holder

         Where two or more persons are registered as joint holders of a share or
shares then in the event of the death of any joint holder or holders the
remaining joint holder or holders shall be absolutely entitled to the said share
or shares and the Company shall recognise no claim in respect of the estate of
any joint holder except in the case of the last survivor of such joint holders.

54.  Share certificates

         (1) Every Member shall be entitled to a certificate under the seal of
the Company (or a facsimile thereof) specifying the number and, where
appropriate, the class of shares held by such Member and whether the same are
fully paid up and, if not, how much has been paid thereon. The certificates for
the Common Shares and Preference Shares shall be in the form of Forms "E" and
"F" in the Schedule hereto. The Board may by resolution determine, either
generally or in a particular case, that any or all signatures on certificates
may be printed thereon or affixed by mechanical means.

         (2) The Company shall be under no obligation to complete and deliver a
share certificate unless specifically called upon to do so by the person to whom
such shares have been allotted.

         (3) If any such certificate shall be proved to the satisfaction of the
Board to have been worn out, lost, mislaid or destroyed the Board may cause a
new certificate to be issued and request an indemnity for the lost certificate
if it sees fit.

         (4) The following legend shall be affixed to the share certificates for
the Preference Shares:

THE PREFERENCE SHARES EVIDENCED BY THIS SHARE CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS ON TRANSFER SET FORTH IN THE BYE-LAWS OF THE COMPANY. NO
REGISTRATION OF TRANSFER OF THESE SHARES WILL BE MADE ON THE BOOKS OF THE
COMPANY OTHER THAN TO (a) Telecom Americas Ltd. and its successors and assigns
or (B) TO A PERMITTED TRANSFEREE OF BCI INVESTMENTS PURSUANT TO AND IN
ACCORDANCE WITH THE BYE-LAWS OF THE COMPANY. THE PREFERENCE SHARES REPRESENTED
BY THIS SHARE CERTIFICATE ARE SUBJECT TO REDEMPTION OR CANCELLATION FOR A PRICE
OF U.S.$0.01 pER SHARE BY THE COMPANY ON THE OCCURRENCE OF CERTAIN CONDITIONS
AND ON THE TERMS SET FORTH IN THE BYE-LAWS of the company.

55.  Calls on shares

         Subject to Bye-law 9 hereof, the Board may from time to time make such
calls as it thinks fit upon the Members in respect of any monies unpaid on the
shares allotted to or held by such Members and, if a call is not paid on or
before the day appointed for payment thereof, the Member may at the discretion
of the Board be liable to pay the Company interest on the amount of such call at
such rate as the Board may determine, from the date when such call was payable
up to the actual date of payment. The joint holders of a share shall be jointly
and severally liable to pay all calls in respect thereof.

56.  Forfeiture of shares

         (1) If any Member fails to pay, on the day appointed for payment
thereof, any call in respect of any share allotted to or held by such Member,
the Board may, at any time thereafter during such time as the call remains
unpaid, direct the Secretary to forward to such Member a notice in the form, or
as near thereto as circumstances admit, of Form "B" in the Schedule hereto.

         (2) If the requirements of such notice are not complied with, any such
share may at any time thereafter before the payment of such call and the
interest due in respect thereof be forfeited by a resolution of the Board to
that effect, and such share shall thereupon become the property of the Company
and may be disposed of as the Board shall determine.

         (3) A Member whose share or shares have been forfeited as aforesaid
shall, notwithstanding such forfeiture, be liable to pay to the Company all
calls owing on such share or shares at the time of the forfeiture and all
interest due thereon.

                               REGISTER OF MEMBERS

57.  Contents of Register of Members

         The Board shall cause to be kept in one or more books a Register of
Members and shall enter therein the particulars required by the Act.

58. Inspection of Register of Members

         The Register of Members shall be open to inspection at the registered
office of the Company on every business day, subject to such reasonable
restrictions as the Board may impose, so that not less than two hours in each
business day be allowed for inspection. The Register of Members may, after
notice has been given by advertisement in an appointed newspaper to that effect,
be closed for any time or times not exceeding in the whole thirty days in each
year.

59.  Determination of record dates

         Notwithstanding any other provision of these Bye-laws, the Board may
fix any date as the record date for:

          (a)  determining the Members entitled to receive any dividend; and

          (b)  determining the Members entitled to receive notice of and to vote
               at any general meeting of the Company.

                               TRANSFER OF SHARES

60. Instrument of transfer

         (1) An instrument of transfer shall be in the form or as near thereto
as circumstances admit of Form "C" in the Schedule hereto or in such other
common form as the Board may accept. Such instrument of transfer shall be signed
by or on behalf of the transferor and transferee provided that, in the case of a
fully paid share, the Board may accept the instrument signed by or on behalf of
the transferor alone. The transferor shall be deemed to remain the holder of
such share until the same has been transferred to the transferee in the Register
of Members.

         (2) The Board may refuse to recognise any instrument of transfer unless
it is accompanied by the certificate in respect of the shares to which it
relates and by such other evidence as the Board may reasonably require to show
the right of the transferor to make the transfer.

61.  Restriction on transfer

         (1) The Preference Shares shall be issued solely to and held initially
by BCI Investments and shall not be transferred to any other Person except to
either (a) Telecom Americas Ltd. and its successors and assigns or (b) to a
Permitted Transferee of BCI Investments holding Telecom Americas Shares
transferred to it pursuant to and in accordance with Section 4.05 of the Joint
Venture Shareholders Agreement (PROVIDED THAT such Permitted Transferee shall be
permitted to hold Preference Shares only for so long as it continues to hold
Telecom Americas Shares and remains a Permitted Transferee of BCI Investments).
There shall be no restriction on the Sale of the Common Shares.

         (2) Except for transfers of Preference Shares permitted under Bye-law
61(1), the Board shall refuse to register the transfer of the Preference Shares.
The Board shall refuse to register a transfer unless all applicable consents,
authorisations and permissions of any governmental body or agency in Bermuda
have been obtained.

         (3) If the Board refuses to register a transfer of any share in
accordance with this Bye-law 61, the Secretary shall, within fifteen days after
the date on which the transfer was lodged with the Company, send to the
transferor and transferee notice of the refusal.

62.  Transfers by joint holders

         The joint holders of any share or shares may transfer such share or
shares to one or more of such joint holders, and the surviving holder or holders
of any share or shares previously held by them jointly with a deceased Member
may transfer any such share to the executors or administrators of such deceased
Member.

                             TRANSMISSION OF SHARES

63.  Representative of deceased Member

         In the case of the death of a Member, the survivor or survivors where
the deceased Member was a joint holder, and the legal personal representatives
of the deceased Member where the deceased Member was a sole holder, shall be the
only persons recognised by the Company as having any title to the deceased
Member's interest in the shares. Nothing herein contained shall release the
estate of a deceased joint holder from any liability in respect of any share
which had been jointly held by such deceased Member with other persons. Subject
to the provisions of Section 52 of the Act, for the purpose of this Bye-law,
"legal personal representative" means the executor or administrator of a
deceased Member or such other person as the Board may in its absolute discretion
decide as being properly authorised to deal with the shares of a deceased
Member.

64.  Registration on death or bankruptcy

         Any person becoming entitled to a share in consequence of the death or
bankruptcy of any Member may be registered as a Member upon such evidence as the
Board may deem sufficient or may elect to nominate some person to be registered
as a transferee of such share, and in such case the person becoming entitled
shall execute in favour of such nominee an instrument of transfer in the form,
or as near thereto as circumstances admit, of Form "D" in the Schedule hereto.
On the presentation thereof to the Board, accompanied by such evidence as the
Board may require to prove the title of the transferor, the transferee shall be
registered as a Member but the Board shall, in either case, have the same right
to decline or suspend registration as it would have had in the case of a
transfer of the share by that Member before such Member's death or bankruptcy,
as the case may be.

                        DIVIDENDS AND OTHER DISTRIBUTIONS

65.  Declaration of dividends by the Board

         The Board may, subject to these Bye-laws (including, without
limitation, Bye-law 9) and in accordance with Section 54 of the Act, declare a
dividend to be paid to the Members holding shares entitled to receive such
dividends, in proportion to the number of shares held by them, and such dividend
may be paid in cash or wholly or partly in specie in which case the Board may
fix the value for distribution in specie of any assets.

66.  Other distributions

         Subject to these Bye-laws (including, without limitation, Bye-law 9),
the Board may declare and make such other distributions (in cash or in specie)
to the Members holding shares entitled to receive such dividends as may be
lawfully made out of the assets of the Company.

67.  Reserve fund

         Subject to these Bye-laws (including, without limitation, Bye-law 9),
the Board may from time to time before declaring a dividend set aside, out of
the surplus or profits of the Company, such sum as it thinks proper as a reserve
fund to be used to meet contingencies or for equalising dividends or for any
other special purpose.

68.  Deduction of Amounts due to the Company

         The Board may deduct from the dividends or distributions payable to any
Member all monies due from such Member to the Company on account of calls or
otherwise.

                                 CAPITALISATION

69.  Issue of bonus shares

         (1) The Board may resolve to capitalise any part of the amount for the
time being standing to the credit of any of the Company's share premium or other
reserve accounts or to the credit of the profit and loss account or otherwise
available for distribution by applying such sum in paying up unissued shares to
be allotted as fully paid bonus shares pro rata to the Members holding Common
Shares.

         (2) The Company may capitalise any sum standing to the credit of a
reserve account or sums otherwise available for dividend or distribution by
applying such amounts in paying up in full partly paid shares of those Members
who would have been entitled to such sums if they were distributed by way of
dividend or distribution.

                        ACCOUNTS AND FINANCIAL STATEMENTS

70.  Records of account

         The Board shall cause to be kept proper records of account in
accordance with United States generally accepted accounting principles with
respect to all transactions of the Company and in particular with respect to:

          (a)  all sums of money received and expended by the Company and the
               matters in respect of which the receipt and expenditure relates;

          (b)  all sales and purchases of goods by the Company; and

          (c)  the assets and liabilities of the Company.

Such records of account shall be kept at the registered office of the Company
or, subject to Section 83 (2) of the Act, at such other place as the Board
thinks fit and shall be available for inspection by the Directors during normal
business hours.

71.  Financial year end

         The financial year end of the Company may be determined by resolution
of the Board and failing such resolution shall be the 31st December in each
year.

72.  Financial statements

         Subject to any rights to waive laying of accounts pursuant to Section
88 of the Act, financial statements as required by the Act shall be laid before
the Members in general meeting.

                                      AUDIT

73.  Appointment of Auditor

         Subject to Section 88 of the Act, at the annual general meeting or at a
subsequent special general meeting in each year, an independent representative
of the Members shall be appointed by them as Auditor of the accounts of the
Company. Such Auditor may be a Member but no Director, Officer or employee of
the Company shall, during his or her continuance in office, be eligible to act
as an Auditor of the Company.

74.  Remuneration of Auditor

         The remuneration of the Auditor shall be fixed by the Company in
general meeting or in such manner as the Members may determine.

75.  Vacation of office of Auditor

         If the office of Auditor becomes vacant by the resignation or death of
the Auditor, or by the Auditor becoming incapable of acting by reason of illness
or other disability at a time when the Auditor's services are required, the
Board shall, as soon as practicable, convene a special general meeting to fill
the vacancy thereby created.

76.  Access to books of the Company

         The Auditor shall at all reasonable times have access to all books kept
by the Company and to all accounts and vouchers relating thereto, and the
Auditor may call on the Directors or Officers of the Company for any information
in their possession relating to the books or affairs of the Company.

77.  Report of the Auditor

         (1) Subject to any rights to waive laying of accounts or appointment of
an Auditor pursuant to Section 88 of the Act, the accounts of the Company shall
be audited at least once in every year.

         (2) The financial statements provided for by these Bye-laws shall be
audited by the Auditor in accordance with United States generally accepted
auditing standards. The Auditor shall make a written report thereon in
accordance with generally accepted auditing standards and the report of the
Auditor shall be submitted to the Members in general meeting.

         (3) The generally accepted auditing standards referred to in
subparagraph (2) of this Bye-law may be those of a country or jurisdiction other
than Bermuda. If so, the financial statements and the report of the Auditor must
disclose this fact and name such country or jurisdiction.

                                     NOTICES

78.  Notices to Members of the Company

         A notice may be given by the Company to any Member either by delivering
it to such Member in person or by sending it to such Member's address in the
Register of Members or to such other address given for the purpose. For the
purposes of this Bye-law, a notice may be sent by mail, courier service, cable,
telex, telecopier, facsimile or other mode of representing words in a legible
and non-transitory form.

79.  Notices to joint Members

         Any notice required to be given to a Member shall, with respect to any
shares held jointly by two or more Persons, be given to each of such Persons.

80.  Service and delivery of notice

         Any notice shall be deemed to have been served at the time when the
same would be delivered in the ordinary course of transmission and, in proving
such service, it shall be sufficient to prove that the notice was properly
addressed and prepaid, if posted, and the time when it was posted, delivered to
the courier or to the cable company or transmitted by telex, facsimile or other
method as the case may be.

                               SEAL OF THE COMPANY

81.  The seal

         The seal of the Company shall be in such form as the Board may from
time to time determine. The Board may adopt one or more duplicate seals for use
outside Bermuda.

82.  Manner in which seal is to be affixed

         The seal of the Company shall not be affixed to any instrument except
attested by the signature of a Director and the Secretary or any two Directors,
or any person appointed by the Board for the purpose, provided that any Director
or Officer, may affix the seal of the Company attested by such Director or
Officer's signature to any authenticated copies of these Bye-laws, the
incorporating documents of the Company, the minutes of any meetings or any other
documents required to be authenticated by such Director, Officer or Resident
Representative.

                                   WINDING-UP

83. Winding-up/distribution by liquidator

         If the Company shall be wound up the liquidator may, with the sanction
of a resolution of the Members, divide amongst the Members holding Common Shares
in specie or in kind the whole or any part of the assets of the Company (whether
they shall consist of property of the same kind or not) and may, for such
purpose, set such value as he or she deems fair upon any property to be divided
as aforesaid and may determine how such division shall be carried out as between
the Members holding Common Shares. The liquidator may, with the like sanction,
vest the whole or any part of such assets in trustees upon such trusts for the
benefit of the Members holding Common Shares as the liquidator shall think fit,
but so that no Member shall be compelled to accept any shares or other
securities or assets whereon there is any liability.

                             ALTERATION OF BYE-LAWS

84.  Alteration of Bye-laws

         No Bye-law shall be rescinded, altered or amended and no new Bye-law
shall be made until the same has been approved by a resolution of the Board in
accordance with Bye-law 9 hereof and by a resolution of the majority of the
Members holding Common Shares voting as a class, and for so long as the
Preference Shares are entitled to voting rights, a resolution of a majority of
the Members holding Preference Shares voting as a class.

                    total sum paid up on all such shares conferring such right.

           (2) Where, in accordance with the provisions of subparagraph (1) of
this Bye-law, a poll is demanded, subject to any rights or restrictions for the
time being lawfully attached to any class of shares, every person present at
such meeting shall have one vote for each share entitled to vote of which such
person is the holder, or for which such person holds a proxy, and such vote
shall be counted in the manner set out in sub-paragraph (4) of this Bye-law or
in the case of a general meeting at which one or more Members are present by
telephone in such manner as the chairman of the meeting may direct and the
result of such poll shall be deemed to be the resolution of the meeting at which
the poll was demanded and shall replace any previous resolution upon the same
matter which has been the subject of a show of hands.

           (3) A poll demanded in accordance with the provisions of subparagraph
(1) of this Bye-law, for the purpose of electing a chairman of the meeting or on
a question of adjournment, shall be taken forthwith and a poll demanded on any

the result of the poll shall be declared by the chairman.

45.        Seniority of joint holders voting

           In the case of joint holders the vote of the senior who tenders a
vote, whether in person or by proxy, shall be accepted to the exclusion of the
votes of the other joint holders, and for this purpose seniority shall be
determined by the order in which the names stand in the Register of Members.

46.        Instrument of proxy

           The instrument appointing a proxy shall be in writing in the form, or
as near thereto as circumstances admit, of Form "A" in the Schedule hereto,

in writing, or if the appointor is a corporation, either under its seal, or
under the hand of a duly authorised officer or attorney. The decision of the
chairman of any general meeting as to the validity of any instrument of proxy
shall be final.

47.        Representation of corporations at meetings

           A corporation which is a Member may, by written instrument, authorise
such person as it thinks fit to act as its representative at any meeting of the
Members and the person so authorised shall be entitled to exercise the same
powers on behalf of the corporation which such person represents as that
corporation could exercise if it were an individual Member. Notwithstanding the
foregoing, the chairman of the meeting may accept such assurances as he or she
thinks fit as to the right of any person to attend and vote at general meetings
on behalf of a corporation which is a Member.

in trust the consideration to which such holders are entitled for a period of
six years.

           (3) The failure of the Company to redeem the shares upon the
occurrence of the Redemption Condition shall not constitute a waiver of the
Company's right and obligation to redeem the Preference Shares.

50.        Power to issue shares

           (1) Prior to the redemption of all of the outstanding Preference
Shares pursuant to Bye-law 49, the Board shall not issue any shares, including
any additional Preference Shares or any other class of shares, other than to
Telecom Americas Ltd. and shall not alter the rights of any shares, without an
amendment to these Bye-laws. After all such Preference Shares have been redeemed
or cancelled, and subject to these Bye-laws and to any resolution of the Members

power to issue any unissued shares of the Company on such terms and conditions
as it may determine and any shares or class of shares may be issued with such
preferred, deferred or other special rights or such restrictions, whether in
regard to dividend, voting, return of capital or otherwise as the Company may
from time to time by resolution of the Members prescribe.

Bye-law shall prohibit transactions mentioned in Sections 39A, 39B and 39C of
the Act.

           (4) The Company may from time to time issue its shares in fractional
denominations and deal with such fractions to the same extent as its whole
shares and shares in fractional denominations shall have in proportion to the
respective fractions represented thereby all of the rights of whole shares
including (but without limiting the generality of the foregoing) the right to
vote, to receive dividends and distributions and to participate in a winding up.

51.        Variation of rights, alteration of share capital and purchase of
shares of the Company

           (1) Subject to Bye-laws 9 and 50 and, for the avoidance of doubt,
Bye-law 51(2), and subject to the provisions of Sections 42 and 43 of the Act,
any preference shares may be issued or converted into shares that, at a
determinable date or at the option of the Company, are liable to be redeemed on
such terms and in such manner as the Company before the issue or conversion may
by resolution of the Members determine.

           (2) If at any time there are different classes of shares outstanding,
the rights attached to any class (unless otherwise provided by the terms of
issue of the shares of that class) may, in addition to any vote of the Members
or the Board otherwise required for the taking of such action, whether or not
the Company is being wound-up, be varied with the consent in writing of the
holders of three-fourths of the issued shares of that class or with the sanction
of a resolution passed by a majority of the votes cast at a separate general
meeting of the holders of the shares of the class in accordance with Section 47
(7) of the Act. The rights conferred upon the holders of the shares of any class
issued with preferred or other rights shall not, unless otherwise expressly
provided by the terms of issue of the shares of that class, be deemed to be
varied by the creation or issue of further shares ranking pari passu therewith.

           (3) The Company may from time to time by resolution of the Members
change the currency denomination of, increase, alter or reduce its share capital
in accordance with the provisions of Sections 45 and 46 of the Act and subject
to Bye-laws 9 and 50 hereof. Where, on any alteration of share capital,
fractions of shares or some other difficulty would arise, the Board may deal
with or resolve the same in such manner as it thinks fit including, without
limiting the generality of the foregoing, the issue to Members, as appropriate,
of fractions of shares and/or arranging for the sale or transfer of the
fractions of shares of Members.

           (4) Except for the redemption of the Preference Shares pursuant to
Bye-law 49 hereof, the Company may not purchase all or any part of its own
shares for so long as the Preference Shares possess voting rights, PROVIDED THAT
at such time as the Preference Shares cease to have any voting rights, the
Company may from time to time purchase its own shares in accordance with the
provisions of Section 42A of the Act.

52.        Registered holder of shares

           (1) The Company shall be entitled to treat the registered holder of
any share as the absolute owner thereof and accordingly shall not be bound to
recognise any equitable or other claim to, or interest in, such share on the
part of any other person.

           (2) Any dividend, interest or other moneys payable in cash in respect
of shares may be paid by cheque or draft sent through the post directed to the
Member at such Member's address in the Register of Members or, in the case of
joint holders, to such person and to such address as the holder or joint holders
may in writing direct. If two or more persons are registered as joint holders of
any shares any one can give an effectual receipt for any dividend paid in
respect of such shares.

53.        Death of a joint holder

           Where two or more persons are registered as joint holders of a share
or shares then in the event of the death of any joint holder or holders the
remaining joint holder or holders shall be absolutely entitled to the said share
or shares and the Company shall recognise no claim in respect of the estate of
any joint holder except in the case of the last survivor of such joint holders.

54.        Share certificates

           (1) Every Member shall be entitled to a certificate under the seal of
the Company (or a facsimile thereof) specifying the number and, where
appropriate, the class of shares held by such Member and whether the same are
fully paid up and, if not, how much has been paid thereon. The certificates for
the Common Shares and Preference Shares shall be in the form of Forms "E" and
"F" in the Schedule hereto. The Board may by resolution determine, either
generally or in a particular case, that any or all signatures on certificates
may be printed thereon or affixed by mechanical means.

           (2) The Company shall be under no obligation to complete and deliver
a share certificate unless specifically called upon to do so by the person to
whom such shares have been allotted.

           (3) If any such certificate shall be proved to the satisfaction of
the Board to have been worn out, lost, mislaid or destroyed the Board may cause
a new certificate to be issued and request an indemnity for the lost certificate
if it sees fit.

           (4) The following legend shall be affixed to the share certificates
for the Preference Shares:

THE PREFERENCE SHARES EVIDENCED BY THIS SHARE CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS ON TRANSFER SET FORTH IN THE BYE-LAWS OF THE COMPANY. NO
REGISTRATION OF TRANSFER OF THESE SHARES WILL BE MADE ON THE BOOKS OF THE
COMPANY OTHER THAN TO (a) Telecom Americas Ltd. and its successors and assigns
or (B) TO A PERMITTED TRANSFEREE OF BCI INVESTMENTS PURSUANT TO AND IN
ACCORDANCE WITH THE BYE-LAWS OF THE COMPANY. THE PREFERENCE SHARES REPRESENTED
BY THIS SHARE CERTIFICATE ARE SUBJECT TO REDEMPTION OR CANCELLATION FOR A PRICE
OF U.S.$0.01 pER SHARE BY THE COMPANY ON THE OCCURRENCE OF CERTAIN CONDITIONS
AND ON THE TERMS SET FORTH IN THE BYE-LAWS of the company.

55.        Calls on shares

           Subject to Bye-law 9 hereof, the Board may from time to time make
such calls as it thinks fit upon the Members in respect of any monies unpaid on
the shares allotted to or held by such Members and, if a call is not paid on or
before the day appointed for payment thereof, the Member may at the discretion
of the Board be liable to pay the Company interest on the amount of such call at
such rate as the Board may determine, from the date when such call was payable
up to the actual date of payment. The joint holders of a share shall be jointly
and severally liable to pay all calls in respect thereof.

56.        Forfeiture of shares

           (1) If any Member fails to pay, on the day appointed for payment
thereof, any call in respect of any share allotted to or held by such Member,
the Board may, at any time thereafter during such time as the call remains
unpaid, direct the Secretary to forward to such Member a notice in the form, or
as near thereto as circumstances admit, of Form "B" in the Schedule hereto.

           (2) If the requirements of such notice are not complied with, any
such share may at any time thereafter before the payment of such call and the
interest due in respect thereof be forfeited by a resolution of the Board to
that effect, and such share shall thereupon become the property of the Company
and may be disposed of as the Board shall determine.

           (3) A Member whose share or shares have been forfeited as aforesaid
shall, notwithstanding such forfeiture, be liable to pay to the Company all
calls owing on such share or shares at the time of the forfeiture and all
interest due thereon.

                               REGISTER OF MEMBERS

57.        Contents of Register of Members

           The Board shall cause to be kept in one or more books a Register of
Members and shall enter therein the particulars required by the Act.

58.        Inspection of Register of Members

           The Register of Members shall be open to inspection at the registered
office of the Company on every business day, subject to such reasonable
restrictions as the Board may impose, so that not less than two hours in each
business day be allowed for inspection. The Register of Members may, after
notice has been given by advertisement in an appointed newspaper to that effect,
be closed for any time or times not exceeding in the whole thirty days in each
year.

59.        Determination of record dates

           Notwithstanding any other provision of these Bye-laws, the Board may
fix any date as the record date for:

               (a)  determining the Members entitled to receive any dividend;
                    and

               (b)  determining the Members entitled to receive notice of and to
                    vote at any general meeting of the Company.

                               TRANSFER OF SHARES

60.        Instrument of transfer

           (1) An instrument of transfer shall be in the form or as near thereto
as circumstances admit of Form "C" in the Schedule hereto or in such other
common form as the Board may accept. Such instrument of transfer shall be signed
by or on behalf of the transferor and transferee provided that, in the case of a
fully paid share, the Board may accept the instrument signed by or on behalf of
the transferor alone. The transferor shall be deemed to remain the holder of
such share until the same has been transferred to the transferee in the Register
of Members.

           (2) The Board may refuse to recognise any instrument of transfer
unless it is accompanied by the certificate in respect of the shares to which it
relates and by such other evidence as the Board may reasonably require to show
the right of the transferor to make the transfer.

61.        Restriction on transfer

           (1) The Preference Shares shall be issued solely to and held
initially by BCI Investments and shall not be transferred to any other Person
except to either (a) Telecom Americas Ltd. and its successors and assigns or (b)
to a Permitted Transferee of BCI Investments holding Telecom Americas Shares
transferred to it pursuant to and in accordance with Section 4.05 of the Joint
Venture Shareholders Agreement (PROVIDED THAT such Permitted Transferee shall be
permitted to hold Preference Shares only for so long as it continues to hold
Telecom Americas Shares and remains a Permitted Transferee of BCI Investments).
There shall be no restriction on the Sale of the Common Shares.

           (2) Except for transfers of Preference Shares permitted under Bye-law
61(1), the Board shall refuse to register the transfer of the Preference Shares.
The Board shall refuse to register a transfer unless all applicable consents,
authorisations and permissions of any governmental body or agency in Bermuda
have been obtained.

           (3) If the Board refuses to register a transfer of any share in
accordance with this Bye-law 61, the Secretary shall, within fifteen days after
the date on which the transfer was lodged with the Company, send to the
transferor and transferee notice of the refusal.

62.        Transfers by joint holders

           The joint holders of any share or shares may transfer such share or
shares to one or more of such joint holders, and the surviving holder or holders
of any share or shares previously held by them jointly with a deceased Member
may transfer any such share to the executors or administrators of such deceased
Member.

                             TRANSMISSION OF SHARES

63.        Representative of deceased Member

           In the case of the death of a Member, the survivor or survivors where
the deceased Member was a joint holder, and the legal personal representatives
of the deceased Member where the deceased Member was a sole holder, shall be the
only persons recognised by the Company as having any title to the deceased
Member's interest in the shares. Nothing herein contained shall release the
estate of a deceased joint holder from any liability in respect of any share
which had been jointly held by such deceased Member with other persons. Subject
to the provisions of Section 52 of the Act, for the purpose of this Bye-law,
"legal personal representative" means the executor or administrator of a
deceased Member or such other person as the Board may in its absolute discretion
decide as being properly authorised to deal with the shares of a deceased
Member.

64.        Registration on death or bankruptcy

           Any person becoming entitled to a share in consequence of the death
or bankruptcy of any Member may be registered as a Member upon such evidence as
the Board may deem sufficient or may elect to nominate some person to be
registered as a transferee of such share, and in such case the person becoming
entitled shall execute in favour of such nominee an instrument of transfer in
the form, or as near thereto as circumstances admit, of Form "D" in the Schedule
hereto. On the presentation thereof to the Board, accompanied by such evidence
as the Board may require to prove the title of the transferor, the transferee
shall be registered as a Member but the Board shall, in either case, have the
same right to decline or suspend registration as it would have had in the case
of a transfer of the share by that Member before such Member's death or
bankruptcy, as the case may be.

                        DIVIDENDS AND OTHER DISTRIBUTIONS

65.        Declaration of dividends by the Board

           The Board may, subject to these Bye-laws (including, without
limitation, Bye-law 9) and in accordance with Section 54 of the Act, declare a
dividend to be paid to the Members holding shares entitled to receive such
dividends, in proportion to the number of shares held by them, and such dividend
may be paid in cash or wholly or partly in specie in which case the Board may
fix the value for distribution in specie of any assets.

66.        Other distributions

           Subject to these Bye-laws (including, without limitation, Bye-law 9),
the Board may declare and make such other distributions (in cash or in specie)
to the Members holding shares entitled to receive such dividends as may be
lawfully made out of the assets of the Company.

67.        Reserve fund

           Subject to these Bye-laws (including, without limitation, Bye-law 9),
the Board may from time to time before declaring a dividend set aside, out of
the surplus or profits of the Company, such sum as it thinks proper as a reserve
fund to be used to meet contingencies or for equalising dividends or for any
other special purpose.

68.        Deduction of Amounts due to the Company

           The Board may deduct from the dividends or distributions payable to
any Member all monies due from such Member to the Company on account of calls or
otherwise.

                                 CAPITALISATION

69.        Issue of bonus shares

           (1) The Board may resolve to capitalise any part of the amount for
the time being standing to the credit of any of the Company's share premium or
other reserve accounts or to the credit of the profit and loss account or
otherwise available for distribution by applying such sum in paying up unissued
shares to be allotted as fully paid bonus shares pro rata to the Members holding
Common Shares.

           (2) The Company may capitalise any sum standing to the credit of a
reserve account or sums otherwise available for dividend or distribution by
applying such amounts in paying up in full partly paid shares of those Members
who would have been entitled to such sums if they were distributed by way of
dividend or distribution.

                        ACCOUNTS AND FINANCIAL STATEMENTS

70.        Records of account

           The Board shall cause to be kept proper records of account in
accordance with United States generally accepted accounting principles with
respect to all transactions of the Company and in particular with respect to:

               (a)  all sums of money received and expended by the Company and
                    the matters in respect of which the receipt and expenditure
                    relates;

               (b)  all sales and purchases of goods by the Company; and

               (c)  the assets and liabilities of the Company.

Such records of account shall be kept at the registered office of the Company
or, subject to Section 83 (2) of the Act, at such other place as the Board
thinks fit and shall be available for inspection by the Directors during normal
business hours.

71.        Financial year end

           The financial year end of the Company may be determined by resolution
of the Board and failing such resolution shall be the 31st December in each
year.

72.        Financial statements

           Subject to any rights to waive laying of accounts pursuant to Section
88 of the Act, financial statements as required by the Act shall be laid before
the Members in general meeting.

                                      AUDIT

73.        Appointment of Auditor

           Subject to Section 88 of the Act, at the annual general meeting or at
a subsequent special general meeting in each year, an independent representative
of the Members shall be appointed by them as Auditor of the accounts of the
Company. Such Auditor may be a Member but no Director, Officer or employee of
the Company shall, during his or her continuance in office, be eligible to act
as an Auditor of the Company.

74.        Remuneration of Auditor

           The remuneration of the Auditor shall be fixed by the Company in
general meeting or in such manner as the Members may determine.

75.        Vacation of office of Auditor

           If the office of Auditor becomes vacant by the resignation or death
of the Auditor, or by the Auditor becoming incapable of acting by reason of
illness or other disability at a time when the Auditor's services are required,
the Board shall, as soon as practicable, convene a special general meeting to
fill the vacancy thereby created.

76.        Access to books of the Company

           The Auditor shall at all reasonable times have access to all books
kept by the Company and to all accounts and vouchers relating thereto, and the
Auditor may call on the Directors or Officers of the Company for any information
in their possession relating to the books or affairs of the Company.

77.        Report of the Auditor

           (1) Subject to any rights to waive laying of accounts or appointment
of an Auditor pursuant to Section 88 of the Act, the accounts of the Company
shall be audited at least once in every year.

           (2) The financial statements provided for by these Bye-laws shall be
audited by the Auditor in accordance with United States generally accepted
auditing standards. The Auditor shall make a written report thereon in
accordance with generally accepted auditing standards and the report of the
Auditor shall be submitted to the Members in general meeting.

           (3) The generally accepted auditing standards referred to in
subparagraph (2) of this Bye-law may be those of a country or jurisdiction other
than Bermuda. If so, the financial statements and the report of the Auditor must
disclose this fact and name such country or jurisdiction.

                                     NOTICES

78.        Notices to Members of the Company

           A notice may be given by the Company to any Member either by
delivering it to such Member in person or by sending it to such Member's address
in the Register of Members or to such other address given for the purpose. For
the purposes of this Bye-law, a notice may be sent by mail, courier service,
cable, telex, telecopier, facsimile or other mode of representing words in a
legible and non-transitory form.

79.        Notices to joint Members

           Any notice required to be given to a Member shall, with respect to
any shares held jointly by two or more Persons, be given to each of such
Persons.

80.        Service and delivery of notice

           Any notice shall be deemed to have been served at the time when the
same would be delivered in the ordinary course of transmission and, in proving
such service, it shall be sufficient to prove that the notice was properly
addressed and prepaid, if posted, and the time when it was posted, delivered to
the courier or to the cable company or transmitted by telex, facsimile or other
method as the case may be.

                               SEAL OF THE COMPANY

81.        The seal

           The seal of the Company shall be in such form as the Board may from
time to time determine. The Board may adopt one or more duplicate seals for use
outside Bermuda.

82.        Manner in which seal is to be affixed

            The seal of the Company shall not be affixed to any instrument
except attested by the signature of a Director and the Secretary or any two
Directors, or any person appointed by the Board for the purpose, provided that
any Director or Officer, may affix the seal of the Company attested by such
Director or Officer's signature to any authenticated copies of these Bye-laws,
the incorporating documents of the Company, the minutes of any meetings or any
other documents required to be authenticated by such Director, Officer or
Resident Representative.

                                   WINDING-UP

83.        Winding-up/distribution by liquidator

           If the Company shall be wound up the liquidator may, with the
sanction of a resolution of the Members, divide amongst the Members holding
Common Shares in specie or in kind the whole or any part of the assets of the
Company (whether they shall consist of property of the same kind or not) and
may, for such purpose, set such value as he or she deems fair upon any property
to be divided as aforesaid and may determine how such division shall be carried
out as between the Members holding Common Shares. The liquidator may, with the
like sanction, vest the whole or any part of such assets in trustees upon such
trusts for the benefit of the Members holding Common Shares as the liquidator
shall think fit, but so that no Member shall be compelled to accept any shares
or other securities or assets whereon there is any liability.

                             ALTERATION OF BYE-LAWS

84.        Alteration of Bye-laws

           No Bye-law shall be rescinded, altered or amended and no new Bye-law
shall be made until the same has been approved by a resolution of the Board in
accordance with Bye-law 9 hereof and by a resolution of the majority of the
Members holding Common Shares voting as a class, and for so long as the
Preference Shares are entitled to voting rights, a resolution of a majority of
the Members holding Preference Shares voting as a class.

               conclusion of the poll, the ballot papers shall be examined and
               counted by a committee of not less than two Members or proxy
               holders appointed by the chairman for the purpose and the result
               of the poll shall be declared by the chairman.

45.        Seniority of joint holders voting

           In the case of joint holders the vote of the senior who tenders a
           vote, whether in person or by proxy, shall be accepted to the
           exclusion of the votes of the other joint holders, and for this
           purpose seniority shall be determined by the order in which the names
           stand in the Register of Members.

46.        Instrument of proxy

           The instrument appointing a proxy shall be in writing in the form, or
           as near thereto as circumstances admit, of Form "A" in the Schedule
           hereto, under the hand of the appointor or of the appointor's
           attorney duly authorised in writing, or if the appointor is a
           corporation, either under its seal, or under the hand of a duly
           authorised officer or attorney. The decision of the chairman of any
           general meeting as to the validity of any instrument of proxy shall
           be final.

47.        Representation of corporations at meetings

           A corporation which is a Member may, by written instrument, authorise
           such person as it thinks fit to act as its representative at any
           meeting of the Members and the person so authorised shall be entitled
           to exercise the same powers on behalf of the corporation which such
           person represents as that corporation could exercise if it were an
           individual Member. Notwithstanding the foregoing, the chairman of the
           meeting may accept such assurances as he or she thinks fit as to the
           right of any person to attend and vote at general meetings on behalf
           of a corporation which is a Member.

                            SHARE CAPITAL AND SHARES

48.        Intentionally Omitted

49.        Intentionally Omitted

50.        Power to issue shares

          (1)  Prior to the redemption of all of the outstanding Preferred
               Shares, the Board shall not issue any shares, including any
               additional Preferred Shares or any other class of shares, other
               than to Telecom Americas Ltd. and shall not alter the rights of
               any shares, without an amendment to the Memorandum. After all
               such Preferred Shares have been redeemed or cancelled, and
               subject to these Articles of Association and to any resolution of
               the Members to the contrary and without prejudice to any special
               rights previously conferred on the holders of any existing shares
               or class of shares, the Board shall have power to issue any
               unissued shares of the Company on such terms and conditions as it
               may determine and any shares or class of shares may be issued
               with such preferred, deferred or other special rights or such
               restrictions, whether in regard to dividend, voting, return of
               capital or otherwise as the Company may from time to time by
               resolution of the Members prescribe.

          (2)  The Board shall, in connection with the issue of any share, have
               the power to pay such commission and brokerage as may be
               permitted by law.

          (3)  The Company may from time to time issue its shares in fractional
               denominations and deal with such fractions to the same extent as
               its whole shares and shares in fractional denominations shall
               have in proportion to the respective fractions represented
               thereby all of the rights of whole shares including (but without
               limiting the generality of the foregoing) the right to vote, to
               receive dividends and distributions and to participate in a
               winding up.

51.        Variation of rights, alteration of share capital and purchase of
           shares of the Company

          (1)  Subject to Regulations 9 and 50 and, for the avoidance of doubt,
               Regulation 51(2), any Preferred Shares may be issued or converted
               into shares that, at a determinable date or at the option of the
               Company, are liable to be redeemed on such terms and in such
               manner as the Company before the issue or conversion may by
               resolution of the Members determine.

          (2)  If at any time there are different classes of shares outstanding,
               the rights attached to any class (unless otherwise provided by
               the terms of issue of the shares of that class) may, in addition
               to any vote of the Members or the Board otherwise required for
               the taking of such action, whether or not the Company is being
               wound-up, be varied with the consent in writing of the holders of
               three-fourths of the issued shares of that class or with the
               sanction of a resolution passed by a majority of the votes cast
               at a separate general meeting of the holders of the shares of the
               class. The rights conferred upon the holders of the shares of any
               class issued with preferred or other rights shall not, unless
               otherwise expressly provided by the terms of issue of the shares
               of that class, be deemed to be varied by the creation or issue of
               further shares ranking pari passu therewith.

          (3)  The Company may from time to time by resolution of the Members
               change the currency denomination of, increase, alter or reduce
               its authorised share capital in accordance with the provisions of
               Section 24 of the Act and subject to Regulations 9 and 50 hereof.
               Where, on any alteration of share capital, fractions of shares or
               some other difficulty would arise, the Board may deal with or
               resolve the same in such manner as it thinks fit including,
               without limiting the generality of the foregoing, the issue to
               Members, as appropriate, of fractions of shares and/or arranging
               for the sale or transfer of the fractions of shares of Members.

          (4)  Except for the redemption of the Preferred Shares pursuant to the
               Memorandum, the Company may not purchase all or any part of its
               own shares for so long as the Preferred Shares possess voting
               rights, PROVIDED THAT at such time as the Preferred Shares cease
               to have any voting rights, the Company may from time to time
               purchase its own shares in accordance with the provisions of
               Section 33 of the Act.

52.        Registered holder of shares

          (1)  The Company shall be entitled to treat the registered holder of
               any share as the absolute owner thereof and accordingly shall not
               be bound to recognise any equitable or other claim to, or
               interest in, such share on the part of any other person.

          (2)  Any dividend, interest or other moneys payable in cash in respect
               of shares may be paid by cheque or draft sent through the post
               directed to the Member at such Member's address in the Register
               of Members or, in the case of joint holders, to such person and
               to such address as the holder or joint holders may in writing
               direct. If two or more persons are registered as joint holders of
               any shares any one can give an effectual receipt for any dividend
               paid in respect of such shares.

53.        Death of a joint holder

           Where two or more persons are registered as joint holders of a share
           or shares then in the event of the death of any joint holder or
           holders the remaining joint holder or holders shall be absolutely
           entitled to the said share or shares and the Company shall recognise
           no claim in respect of the estate of any joint holder except in the
           case of the last survivor of such joint holders.

54.        Share certificates

          (1)  Every Member shall be entitled to a certificate under the seal of
               the Company (or a facsimile thereof) specifying the number and,
               where appropriate, the class of shares held by such Member and
               whether the same are fully paid up and, if not, how much has been
               paid thereon. The certificates for the Common Shares and
               Preferred Shares shall be in the form of Forms "E" and "F" in the
               Schedule hereto. The Board may by resolution determine, either
               generally or in a particular case, that any or all signatures on
               certificates may be printed thereon or affixed by mechanical
               means.

          (2)  The Company shall be under no obligation to complete and deliver
               a share certificate unless specifically called upon to do so by
               the person to whom such shares have been allotted.

          (3)  If any such certificate shall be proved to the satisfaction of
               the Board to have been worn out, lost, mislaid or destroyed the
               Board may cause a new certificate to be issued and request an
               indemnity for the lost certificate if it sees fit.

          (4)  The following legend shall be affixed to the share certificates
               for the Preferred Shares:

                    THE PREFERRED SHARES EVIDENCED BY THIS SHARE CERTIFICATE ARE
                    SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER SET FORTH IN THE
                    MEMORANDUM AND ARTICLES OF ASSOCIATION OF THE COMPANY. NO
                    REGISTRATION OF TRANSFER OF THESE SHARES WILL BE MADE ON THE
                    BOOKS OF THE COMPANY OTHER THAN TO (A) TELECOM AMERICAS LTD.
                    AND ITS SUCCESSORS AND ASSIGNS OR (B) TO A PERMITTED
                    TRANSFEREE OF BCI INVESTMENTS PURSUANT TO AND IN ACCORDANCE
                    WITH THE MEMORANDUM AND ARTICLES OF ASSOCIATION OF THE
                    COMPANY. THE PREFERRED SHARES REPRESENTED BY THIS SHARE
                    CERTIFICATE ARE SUBJECT TO REDEMPTION OR CANCELLATION FOR A
                    PRICE OF U.S.$0.01 PER SHARE BY THE COMPANY ON THE
                    OCCURRENCE OF CERTAIN CONDITIONS AND ON THE TERMS SET FORTH
                    IN THE MEMORANDUM AND ARTICLES OF ASSOCIATION OF THE
                    COMPANY.

55.        Intentionally Omitted

56.        Forfeiture of shares

          (1)  If any Member fails to pay up, on the day appointed for payment
               thereof, any share allotted to or held by such Member, the Board
               may, at any time thereafter during such time as the call remains
               unpaid, direct the Secretary to forward to such Member a notice
               in the form, or as near thereto as circumstances admit, of Form
               "B" in the Schedule hereto.

          (2)  If the requirements of such notice are not complied with, any
               such share may at any time thereafter before payment and the
               interest due in respect thereof be forfeited by a resolution of
               the Board to that effect, and such share shall thereupon become
               the property of the Company and may be disposed of as the Board
               shall determine.

          (3)  A Member whose share or shares have been forfeited as aforesaid
               shall, notwithstanding such forfeiture, be liable to pay to the
               Company all calls owing on such share or shares at the time of
               the forfeiture and all interest due thereon.

                               REGISTER OF MEMBERS

57.        Contents of Register of Members

           The Board shall cause to be kept in one or more books a Register of
           Members and shall enter therein the particulars required by the Act.

58.        Inspection of Register of Members

           The Register of Members shall be open to inspection as required under
           the Act.

59.        Determination of record dates

           Notwithstanding any other provision of these Articles of Association,
           the Board may fix any date as the record date for:

          (a)  determining the Members entitled to receive any dividend; and

          (b)  determining the Members entitled to receive notice of and to vote
               at any general meeting of the Company.

                               TRANSFER OF SHARES

60.        Instrument of transfer

          (1)  An instrument of transfer shall be in the form or as near thereto
               as circumstances admit of Form "C" in the Schedule hereto or in
               such other common form as the Board may accept. Such instrument
               of transfer shall be signed by or on behalf of the transferor and
               transferee provided that, in the case of a fully paid share, the
               Board may accept the instrument signed by or on behalf of the
               transferor alone. The transferor shall be deemed to remain the
               holder of such share until the same has been transferred to the
               transferee in the Register of Members.

          (2)  The Board may refuse to recognise any instrument of transfer
               unless it is accompanied by the certificate in respect of the
               shares to which it relates and by such other evidence as the
               Board may reasonably require to show the right of the transferor
               to make the transfer.

61.        Restriction on transfer

          (1)  The Preferred Shares shall be issued solely to and held initially
               by BCI Investments and shall not be transferred to any other
               Person except to either (a) Telecom Americas Ltd. and its
               successors and assigns or (b) to a Permitted Transferee of BCI
               Investments holding Telecom Americas Shares transferred to it
               pursuant to and in accordance with Section 4.05 of the Joint
               Venture Shareholders Agreement (PROVIDED THAT such Permitted
               Transferee shall be permitted to hold Preferred Shares only for
               so long as it continues to hold Telecom Americas Shares and
               remains a Permitted Transferee of BCI Investments). There shall
               be no restriction on the Sale of the Common Shares.

          (2)  Except for transfers of Preferred Shares permitted under
               Regulation 61(1), the Board shall refuse to register the transfer
               of the Preferred Shares.

          (3)  If the Board refuses to register a transfer of any share in
               accordance with this Regulation 61, the Secretary shall, within
               fifteen days after the date on which the transfer was lodged with
               the Company, send to the transferor and transferee notice of the
               refusal.

62.        Transfers by joint holders

           The joint holders of any share or shares may transfer such share or
           shares to one or more of such joint holders, and the surviving holder
           or holders of any share or shares previously held by them jointly
           with a deceased Member may transfer any such share to the executors
           or administrators of such deceased Member.

                             TRANSMISSION OF SHARES

63.        Representative of deceased Member

           In the case of the death of a Member, the survivor or survivors where
           the deceased Member was a joint holder, and the legal personal
           representatives of the deceased Member where the deceased Member was
           a sole holder, shall be the only persons recognised by the Company as
           having any title to the deceased Member's interest in the shares.
           Nothing herein contained shall release the estate of a deceased joint
           holder from any liability in respect of any share which had been
           jointly held by such deceased Member with other persons., For the
           purpose of this Regulation, "legal personal representative" means the
           executor or administrator of a deceased Member or such other person
           as the Board may in its absolute discretion decide as being properly
           authorised to deal with the shares of a deceased Member.

64.        Registration on death or bankruptcy

           Any person becoming entitled to a share in consequence of the death
           or bankruptcy of any Member may be registered as a Member upon such
           evidence as the Board may deem sufficient or may elect to nominate
           some person to be registered as a transferee of such share, and in
           such case the person becoming entitled shall execute in favour of
           such nominee an instrument of transfer in the form, or as near
           thereto as circumstances admit, of Form "D" in the Schedule hereto.
           On the presentation thereof to the Board, accompanied by such
           evidence as the Board may require to prove the title of the
           transferor, the transferee shall be registered as a Member but the
           Board shall, in either case, have the same right to decline or
           suspend registration as it would have had in the case of a transfer
           of the share by that Member before such Member's death or bankruptcy,
           as the case may be.

                        DIVIDENDS AND OTHER DISTRIBUTIONS

65.        Declaration of dividends by the Board

           The Board may, subject to the Memorandum and these Articles of
           Association (including, without limitation, Regulation 9) and in
           accordance with Section 36 of the Act, declare a dividend to be paid
           to the Members holding shares entitled to receive such dividends, in
           proportion to the number of shares held by them, and such dividend
           may be paid in cash or wholly or partly in specie in which case the
           Board may fix the value for distribution in specie of any assets.

66.        Other distributions

           Subject to the Memorandum and these Articles of Association
           (including, without limitation, Regulation 9), the Board may declare
           and make such other distributions (in cash or in specie) to the
           Members holding shares entitled to receive such dividends as may be
           lawfully made out of the assets of the Company.

67.        Reserve fund

           Subject to the Memorandum and these Articles of Association
           (including, without limitation, Regulation 9), the Board may from
           time to time before declaring a dividend set aside, out of the
           surplus or profits of the Company, such sum as it thinks proper as a
           reserve fund to be used to meet contingencies or for equalising
           dividends or for any other special purpose.

68.        Deduction of Amounts due to the Company

           The Board may deduct from the dividends or distributions payable to
           any Member all monies due from such Member to the Company on account
           of calls or otherwise.

                                 CAPITALISATION

69.        Issue of bonus shares

          (1)  The Board may resolve to capitalise any part of the amount for
               the time being standing to the credit of any of the Company's
               surplus or other reserve accounts or to the credit of the profit
               and loss account or otherwise available for distribution by
               applying such sum in paying up unissued shares to be allotted as
               fully paid bonus shares pro rata to the Members holding Common
               Shares.

          (2)  The Company may capitalise any sum standing to the credit of a
               reserve account or sums otherwise available for dividend or
               distribution by applying such amounts in paying up in full partly
               paid shares of those Members who would have been entitled to such
               sums if they were distributed by way of dividend or distribution.

                        ACCOUNTS AND FINANCIAL STATEMENTS

70.        Records of account

           The Board shall cause to be kept proper records of account in
           accordance with United States generally accepted accounting
           principles with respect to all transactions of the Company and in
           particular with respect to:

          (a)  all sums of money received and expended by the Company and the
               matters in respect of which the receipt and expenditure relates;

          (b)  all sales and purchases of goods by the Company; and

          (c)  the assets and liabilities of the Company.

           Such records of account shall be kept at the registered office of the
           Company or at such other place as the Board thinks fit and shall be
           available for inspection by the Directors during normal business
           hours.

71.        Financial year end

           The financial year end of the Company may be determined by resolution
           of the Board and failing such resolution shall be the 31st December
           in each year.

72.        Financial statements

           Subject to the Members waiving this requirement, financial accounts

is a company, duly organized, validly existing and in good standing under the
laws of the Cayman Islands and has all requisite corporate power and authority
to own and operate its properties, to carry on its business and to execute,
deliver and perform all of its obligations under this Agreement.

           (b) Capitalization of Permitted SBCI Subsidiary. All of the issued
and outstanding capital stock and other Equity Interests of the Permitted SBCI
Subsidiary are owned beneficially and of record by SBCI and the other holders
set forth on Schedule C attached hereto, in the amounts set forth opposite the
name of each such holder on Schedule C attached hereto (the "SBCI Majority
Equity Interests"). Except as set forth in Schedule C attached hereto, no SBCI
Company is a party or subject to, has authorized, issued or outstanding or is
bound by, any Transfer Agreements in respect of any class of capital stock or
other Equity Interests of the Permitted SBCI Subsidiary. Except as set forth on
Schedule C attached hereto, no Encumbrance on any of SBCI Majority Equity
Interests exists or has been recorded on the share registry of the Permitted
SBCI Subsidiary. Except as set forth on Schedule C attached hereto, there are no
voting trusts, stockholder agreements, proxies or other agreements or
undertakings in effect with respect to the voting, ownership or transfer of any
Equity Interests of the Permitted SBCI Subsidiary.

           (c) Authority. The execution, delivery and performance by each SBCI
Company of this Agreement (i) have been duly authorized by all necessary
corporate action; (ii) will not conflict with or violate any Law or Governmental
Order applicable to such SBCI Company or any of its assets, properties or
businesses; and (iii) will not violate, conflict with or result in a breach of
any provision of, or result in the imposition of any Encumbrance upon any of the
assets of the SBCI Companies under, any of its Constitutive Documents or any
agreement or other requirement by which it or any of its properties may be bound
or affected. Each SBCI Company has duly executed and delivered this Agreement,
and this Agreement constitutes the legal, valid and binding obligation of each
SBCI Company enforceable in accordance with its terms, except as the
enforceability hereof may be limited by the Enforceability Exceptions. No
consent of any Person, including the shareholders of the SBCI Companies, is
required in connection with the execution, delivery and performance of this
Agreement or the validity or enforceability of this Agreement against the SBCI
Companies, except such consents as have been obtained.

           (d) Government Approval. The execution, delivery and performance by
each SBCI Company of this Agreement do not and will not require any consent,
approval, authorization or other order of, action by, filing with or
notification to, any Governmental Authority.

           (e) No Immunity. Each SBCI Company is subject to civil and commercial
law with respect to its obligations hereunder and under the other Transaction
Documents to which it is a party, and its execution, delivery and performance of
this Agreement and the other Transaction Documents to which each is a party
constitute private and commercial acts rather than public or governmental acts.
No SBCI Company or any of its respective properties or revenues have any
immunity from suit, court jurisdiction, attachment prior to judgment, attachment
in aid of execution of a judgment, set-off, execution of a judgment or from any
other legal process with respect to its respective obligations under this
Agreement.

           (f) Control. No Person other than SBCI has the power, by contract or
otherwise, to direct or influence the exercise by the Permitted SBCI Subsidiary
of any rights under this Agreement or the other Transaction Documents to which
the Permitted SBCI Subsidiary is a party, including, without limitation, rights
pursuant to Section 3.08 of the Shareholders Agreement.

           5. Covenants of the Permitted Subsidiaries. Each Permitted Subsidiary
covenants and agrees, with respect to itself only, as follows:

           (a) Improper Sale or Encumbrance. No Permitted Subsidiary shall
recognize any purported Sale of, or Encumbrance with respect to, any shares of
its capital stock or other Equity Interests in violation of this Agreement or
the other Transaction Documents, and any such Sale or Encumbrance shall be null
and void and the Permitted Subsidiary shall not give any effect in its stock
records to such attempted Sale or Encumbrance.

           (b) Implementation. Such Permitted Subsidiary shall take all actions
as shall be necessary to cause the effective implementation of the provisions of
Section 5(a), including registration of this Agreement on its books and
registration with or notification to the appropriate Governmental Authority, if
any.

           (c) Legend. Such Permitted Subsidiary shall cause a legend to be
affixed to all certificates representing its capital stock owned directly or
indirectly by the Venturer of such Permitted Subsidiary, stating that the
transfer of such capital stock is restricted by the terms of this Agreement and
the other Transaction Documents.

           6. Covenants of the Venturers. Each Venturer covenants and agrees,
with respect to itself only, as set forth below:

           (a) Retention of Stock of the Permitted Subsidiaries. Such Venturer
(i) shall maintain directly or indirectly legal and beneficial ownership of a
majority of the issued and outstanding capital stock of each of its Permitted
Subsidiaries and of all other Equity Interests or securities convertible into,
or exercisable for, any shares of the capital stock or other Equity Interests of
any Permitted Subsidiary held by it; which capital stock and other Equity
Interests shall at all times represent a majority of the economic and voting
interest in each such Permitted Subsidiary, (ii) shall not, except in accordance
with Section 4.06 of the Shareholders Agreement, directly or indirectly sell,
assign, transfer or otherwise dispose of, whether voluntarily or involuntarily,
any such capital stock or other Equity Interests or securities convertible into,
or exercisable for, any shares of the capital stock or other Equity Interests of
any Permitted Subsidiary held directly or indirectly by it if the effect of any
such sale, assignment, transfer or disposal would be to reduce the capital stock
or other Equity Interests held directly or indirectly by such Venturer to less
than a majority of the economic and voting interest in such Permitted
Subsidiary, and (iii) shall not issue, or permit the issuance of, subscriptions,
options, warrants, calls or preemptive rights that relate to the capital stock
of any Subsidiary or Affiliate if the effect of any such issuance would be to
reduce the capital stock or other Equity Interests held directly or indirectly
by such Venturer to less than a majority of the economic and voting interest in
such Permitted Subsidiary.

           (b) Encumbrances. Such Venturer shall not create, assume, or
otherwise permit to exist directly or indirectly any Encumbrance on any of the
capital stock of the Permitted Subsidiary held by it or on any of the capital
stock of any Subsidiary or Affiliate that directly or indirectly holds any of
the capital stock of such Permitted Subsidiary.

           (c) Compliance with Affirmative and Negative Covenants. Such Venturer
shall perform and comply with each of the covenants under the Shareholders
Agreement and any other Transaction Document applicable to any Permitted
Subsidiary held by it (which covenants shall be deemed to be incorporated herein
as if the same were set out in full).

           (d) Control. Such Venturer shall not permit or allow any Person other
than the Venturer or its Subsidiaries, by contract or otherwise, to direct or
influence the exercise by each of its Permitted Subsidiaries of any rights under
this Agreement or the other Transaction Documents to which such Permitted
Subsidiaries are a party, including, without limitation, rights pursuant to
Section 3.08 of the Shareholders Agreement.

           7. Guarantee. (a) By execution of this Agreement, each Venturer
hereby absolutely, unconditionally and irrevocably guaranties (the "Guarantee")
all of the terms, provisions, representations, warranties, covenants and
undertakings of any Permitted Subsidiary held by it, that are set forth herein,
in the Shareholders Agreement and each of the other Transaction Documents to
which any Permitted Subsidiary held by it is a party (collectively, the
"Permitted Subsidiary Agreements").

           (a) The obligations of each Venturer under the Guarantee are
independent obligations of such Venturer and a separate action or actions may be
brought and prosecuted against any such Venturer, regardless of whether any
action is brought against its Permitted Subsidiary or whether such Permitted
Subsidiary is joined in any such action or actions.

           (b) The liability of each Venturer under the Guarantee shall be
irrevocable, absolute and unconditional; provided, that, except as set forth in
(i) the Guaranty dated as of November [__], 2000 by BCI in favor of Ivey Holdco
in respect of the BCI Promissory Note, (ii) the Guaranty dated as of November
[__], 2000 by BCI in favor of Ivey Holdco in respect of the BCI Special Notes
and (iii) the Guaranty dated as of November [__], 2000 by America Movil in favor
of Ivey Holdco, such Venturer shall be entitled to any defenses its Permitted
Subsidiary may now or hereafter have in any way relating to the Permitted
Subsidiary Agreements or any other circumstance (including, without limitation,
any statute of limitations) or any existence of or reliance on any
representation by any Person that might otherwise constitute a defense available
to, or a discharge of, such Venturer's Permitted Subsidiary. The Guarantee shall
continue to be effective and reinstated, as the case may be, upon the
insolvency, bankruptcy or reorganization of any Permitted Subsidiary.

           (c) Each Venturer hereby waives promptness, diligence, notice of
acceptance and any other notice with respect to any of its obligations under the
Guarantee. Each Venturer waives any right to revoke the Guarantee, and
acknowledges and agrees that the Guarantee is continuing in nature and applies
to all obligations of such Venturer hereunder, whether existing now or in the
future. Each Venturer acknowledges that it will receive substantial direct and
indirect benefits from the Permitted Subsidiary Agreements and that the waivers
set forth in this Section 7 are knowingly made in contemplation of such
benefits.

           (d) The Guarantee of each Venturer shall remain in full force and
effect, and the obligations of each Venturer thereunder shall continue and not
be discharged until such time as the obligations of any of its Permitted
Subsidiaries under each Permitted Subsidiary Agreement shall have terminated and
by of no further force and effect.

           8. Notices. All notices, requests, claims, demands and other
communications hereunder shall be in writing and shall be given or made (and

under the laws of Canada (the "Corporation"), and the shareholders of the

Consolidation, each Shareholder and the Corporation has agreed to enter into
this Agreement.

           NOW, THEREFORE, in consideration of the premises and the mutual
agreements and covenants hereinafter set forth, the parties hereby agree as

the Corporation.

           "Registrable Shares" means the Common Shares issuable or issued in a
Qualified Offer and the Common Shares held from time to time by the Original

Registrable Shares being registered), but excluding Selling Expenses, if any,
which shall be borne by the Holders holding Common Shares being registered, in
all cases.

           "Rule 144" means Rule 144 promulgated under the Securities Act or any
successor rule thereto or any complementary rule thereto (such as Rule 144A).

           SECTION 2. Request for Registration. (a) At any time after the date
hereof, if the Corporation shall receive from any Shareholder (in such capacity,
a "Requesting Shareholder"), a written request that the Corporation effect any
registration under the Securities Act, or, mutatis mutandis, under the
securities Laws then applicable in Canada, with respect to the sale and
distribution of all or a part of the Registrable Shares in a public offering,
the Corporation will:

          (i) promptly give written notice of the proposed registration,
     qualification or compliance to each of the other Shareholders
     (collectively, the "Non-Requesting Shareholders"); and

          (ii) as soon as practicable, use its best efforts to effect such
     registration (including, without limitation, the execution of an
     undertaking to file post-effective amendments, appropriate qualification
     under applicable securities Laws, including, without limitation, "blue sky"
     laws, and appropriate compliance with applicable regulations issued under
     the Securities Act or the securities Laws then applicable in Canada, as the
     case may be) as may be so requested and as would permit or facilitate the
     sale and distribution of all or such portion of such Registrable Shares as
     are specified in such request, together with all or such portion of the
     Registrable Shares of the Non-Requesting Shareholder joining in such
     request as are specified in a written request received by the Corporation
     within ten (10) Business Days after written notice from the Corporation is
     given under clause 2(a)(i) above; provided that the Corporation shall not
     be obligated to effect, or take any action to effect, any such registration
     pursuant to this Section 2:

               (A) for a period of up to 150 days (a "Deferral Period"), each of
          which Deferral Periods may be renewed for an additional Deferral
          Period, in the case of any Deferred Period (or its renewal), if the
          board of directors of the Corporation (1) determines in good faith
          that (a) it is in possession of material, nonpublic information
          concerning an acquisition, merger, recapitalization, consolidation,
          reorganization, financing or other material transaction by or of the
          Corporation or concerning pending or threatened litigation, and (b)
          disclosure of such information would jeopardize any such transaction
          or litigation and would be seriously detrimental to the Corporation
          and (2) delivers written notice to the Requesting Shareholders and
          Non-Requesting Shareholders that, in its good faith judgment, it would
          not be in the best interests of the shareholders of the Corporation
          for such Registration to be effected;

               (B) in any particular jurisdiction in which the Corporation would
          be required to execute a general consent to service of process in
          effecting such registration, qualification or compliance, unless the
          Corporation is already subject to service in such jurisdiction and
          except as may be required by the Securities Act or applicable rules or
          regulations thereunder;

               (C) with respect to any Original Shareholder (together with its
          Permitted Transferees and Specific Assignees), after the Corporation
          has effected three (3) registrations pursuant to this Section 2(a) at
          the request of such Original Shareholder (together with its Permitted
          Transferees and Specific Assignees), provided, however, that, after
          the Corporation has effected three such registrations for such
          Original Shareholder (together with its Permitted Transferees and
          Specific Assignees), its obligation under this Section 2 to effect
          each registration requested by such Shareholder shall continue for the
          term of this Agreement to the extent, and solely to the extent, that
          such Shareholder shall have agreed that Section 4 hereof shall be
          inapplicable to any such registration and that all Registration
          Expenses and Selling Expenses in connection with any such requested
          registration shall be borne by such Shareholder (or pro rata among it
          and the other selling --- ---- Shareholders, as the case may be);
          provided, further however, that any request under Section 2(a)
          -------- shall be deemed not to have been made if (i) it does not
          result in a registration that is declared or ordered effective by the
          applicable governmental authorities or agencies, including without
          limitation, the SEC, and that remains effective for not less than 180
          days (or such shorter period as will terminate when all Registrable
          Shares covered by such registration have been sold or withdrawn), or,
          if such registration relates to an underwritten offering, such longer
          period, if any, as in the opinion of counsel for the underwriters a
          prospectus is required by law to be delivered in connection with sales
          of the Registrable Shares by an underwriter or dealer (in either case,
          such period being the "Demand Period"), (ii) (x) during the Demand
          Period such registration is terminated by any stop
          order, injunction or other order or requirement of any governmental
          agency or court or (y) the conditions to closing specified in the
          underwriting agreement, if any, entered into in connection with such
          registration are not satisfied other than by reason of a wrongful act,
          misrepresentation or breach of an applicable underwriting agreement by
          the selling Holders of Registrable Shares, (iii) the Requesting
          Holders withdraw their request for registration and bear the
          Registration Expenses, all in accordance with Section 4 below, or (iv)
          more than 40% of the aggregate number of all Registrable Shares
          requested by such Shareholder to be included in such registration are
          excluded from the offering pursuant to Section 2(b).

               (D) if the Registrable Shares requested by the Requesting
          Shareholder and any Non-Requesting Shareholder to be registered
          pursuant to such request do not represent in the aggregate at least 5%
          of the then outstanding Registrable Shares.

The registration statement filed pursuant to the request of the Requesting
Shareholders and any Non-Requesting Shareholder may, subject to the provisions
of Section 2(b) below, include Primary Shares.

           (b) The Corporation shall be entitled to select the managing
underwriter of the underwriting; provided, however, that any such managing
underwriter shall be an investment banking firm of internationally recognized
reputation acceptable to the selling Shareholders representing a majority of the
Registrable Shares to be included in such registration. The Requesting
Shareholders and the Non-Requesting Shareholders (collectively, the "Holders")
proposing to distribute their securities through such underwriting shall enter
into an underwriting agreement in customary form with the managing underwriter
or underwriters selected for such underwriting by the Corporation reasonably
acceptable to the Corporation. Notwithstanding any other provision of this
Section 2, if the managing underwriter advises the Requesting Shareholders in
writing that the inclusion of all Registrable Shares and/or Primary Shares
proposed to be included in such registration would interfere with the successful
marketing (including pricing) of the Registrable Shares proposed to be included
in such registration, then the number of Registrable Shares and/or Primary
Shares to be included in such registration shall be reduced to such number as
shall, in the managing underwriters opinion, not be likely to have such an
effect, which shall be included in the following order:

          (i) first, the Registrable Shares requested to be included in such
     registration that are held by the Requesting Shareholders (or, if
     necessary, such Registrable Shares pro rata among the holders thereof based
     upon the number of Registrable Shares requested to be registered by each
     such holder);

          (ii) second, the Registrable Shares requested to be included in such
     registration that are held by the Non-Requesting Shareholders (or, if
     necessary, such Registrable Shares pro rata among the holders thereof based
     upon the number of Registrable Shares requested to be registered by each
     such holder); and

          (iii) third, the Primary Shares.

           No Registrable Shares or Primary Shares excluded from the
underwriting by reason of the managing underwriter's marketing limitation shall
be included in such registration.

           (c) In the event that a registration is requested under this Section
2 and each of the Requesting Shareholders making such request later determine
not to sell their Registrable Securities in connection with the registration
requested, then the Requesting Shareholders shall give prompt notice to the
Corporation and the other Shareholders, as applicable, that the registration
requested is no longer required and the request is thereby withdrawn. Upon
receipt of such notice, the Corporation shall cease all efforts to secure
registration and shall take all action necessary and reasonably practicable to
prevent the commencement of effectiveness for any registration statement that it
is preparing or has prepared in connection with the withdrawn request.

           SECTION 3. Piggyback Registration. (a) If the Corporation at any time
proposes to register any Common Shares under the Securities Act that would
permit registration of Registrable Shares for sale to the public under the
Securities Act, or, mutatis mutandis, under the securities Laws then applicable
in Canada (whether for its own account or for the account of its shareholders),
the Corporation will, each such time, give prompt written notice to all holders
of Registrable Shares of its intention to do so, describing such securities and
specifying the form and manner and the other relevant facts involved in such
proposed registration (including, without limitation, whether or not such
registration will be in connection with an underwritten offering of Common
Shares and, if so, the identity of the managing underwriter and whether such
offering will be pursuant to a "best efforts" or "firm commitment"
underwriting). Upon the written request of the holders of Registrable Shares to
include Registrable Shares in such registration (which request (i) must be
delivered to the Corporation within 30 days after delivery by the Corporation of
any notice pursuant to this Section 3(a), (ii) shall specify the number of
Registrable Shares proposed to be included in such registration and (iii) shall
state the intended method of disposition of such Registrable Shares), the
Corporation shall use its best efforts to cause all such Registrable Shares to
be included in such registration on the same terms and conditions as the
securities otherwise being sold in such registration; provided, however, that:

          (i) if, at any time after giving such written notice of its intention
     to register any of such securities proposed to be registered by the
     Corporation and prior to the effective date of the registration statement
     filed in connection with such registration, the Corporation shall determine
     for any reason not to register such securities, the Corporation may, at its
     election, give written notice of such determination to each holder of
     Registrable Shares that has requested to register Registrable Shares and,
     thereupon, the Corporation shall be relieved of its obligation to register
     any Registrable Shares in connection with such registration (but not of its
     obligation to pay the Registration Expenses in connection therewith to the
     extent provided in Section 4 below); and

          (ii) if (A) the registration so proposed by the Corporation involves
     an underwritten offering of the securities to be so registered, to be
     distributed by or through one or more underwriters of internationally
     recognized standing under underwriting terms appropriate for such a
     transaction, and (B) the managing underwriter of such underwritten offering
     shall advise the Corporation in writing that, in its judgment, the number
     of Registrable Shares and any other securities proposed to be included in
     such offering by the Corporation should be limited (1) due to market
     conditions or (2) because inclusion of all Registrable Shares proposed to
     be included in such registration is reasonably likely to have a significant
     adverse effect on the successful marketing (including pricing) of the
     Primary Shares proposed to be registered by the Corporation, then the
     Corporation will promptly advise each such Holder of Registrable Shares
     thereof and may require, by written notice to each such Holder accompanying
     such advice, that, to the extent necessary to meet such limitation, the
     number of Primary Shares and Registrable Shares proposed to be included in
     such registration shall be reduced to such number as shall, in the managing
     underwriter's opinion, not be likely to have such an effect included in the
     following order:

               (x) first, the Primary Shares; and

               (y) second, the Registrable Shares requested to be included in
          such registration (or, if necessary, such Registrable Shares pro rata
          among the holders thereof based upon the number of Registrable Shares
          requested to be registered by each such holder).

           (b) The Corporation shall not be obligated to effect any registration
of Registrable Shares under this Section 3 that is incidental to the
registration of any of its securities in connection with any merger,
acquisition, exchange offer, dividend reinvestment plan or stock option or other
employee benefit plan.

           SECTION 4. Expenses. Except as provided for in Section 2(a)(ii)(C),
all Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to this Agreement shall be borne by the
Corporation, and all Selling Expenses shall be borne by the Holders of the
securities so registered pro rata on the basis of the number of their shares so
registered; provided, however, that if, as a result of the withdrawal of a
request for registration by the Requesting Holders, as applicable, the
registration statement does not become effective, the Requesting Holders may
elect to bear the Registration Expenses (pro rata on the basis of the number of
their shares so included in the registration request, or on such other basis as
such Requesting Holders may agree), in which case such registration shall not be
counted as a registration pursuant to Section 2(a)(ii)(C).

           SECTION 5. Holdback Agreement. (a) If the Corporation at any time
shall register Common Shares under the Securities Act pursuant to Sections 2 or
3 hereof for sale to the public, any Shareholders that participate in such
registration shall not sell publicly, or otherwise dispose publicly of, any
Registrable Shares (other than those Common Shares included in such registration
pursuant to Sections 2 or 3 hereof) without the prior written consent of the
Corporation, for a period as shall be determined by the relevant managing
underwriters acting reasonably, which period shall begin not more than 7 days
prior to the initial filing of the registration statement pursuant to which such
public offering shall be made and shall not last more than 90 days after the
effective date of such registration statement; provided, however, that the
officers and directors of the Corporation who own Capital Stock of the
Corporation shall each be subject to similar restrictions. The Corporation shall
obtain the agreement of any Person permitted to sell shares of stock in such
registration to be bound by and to comply with this Section 5 as if such Person
were a Shareholder hereunder.

           (b) If the Corporation shall at any time pursuant to Sections 2 or 3
of this Agreement register under the Securities Act Registrable Shares for sale
to the public pursuant to an underwritten offering, the Corporation shall not
effect any public sale or distribution of securities similar to those being
registered (excluding any transaction of the type identified or contemplated in
Section 3(b) above), or any securities convertible into or exercisable or
exchangeable for such securities, for such period as shall be determined by the
managing underwriters which period shall not begin more than 7 days prior to the
initial filing and shall not extend more than 90 days after the effective date
of such registration statement.

           SECTION 6. Preparation and Filing. (a) If and whenever the
Corporation is under an obligation pursuant to the provisions of this Agreement
to use its best efforts to effect the registration of any Registrable Shares,
the Corporation shall, with respect to such registration (which, for the
avoidance of doubt, shall be a registration in the jurisdiction requested by the
Requesting Shareholder pursuant to Section 2(a) in the case of a registration
under Section 2 hereof), as expeditiously as is reasonable:

          (i) prepare and file a registration statement, in the case of a
     registration request pursuant to Section 2 within 90 days of such request,
     under the Securities Act or similar such document under applicable Canadian
     securities Laws that registers such Registrable Shares to become and remain
     effective for a period of six months or, if earlier, until all of such
     Registrable Shares have been disposed of;

          (ii) prepare and file with the Commission or with the applicable
     Canadian securities regulatory authorities, as the case may be, such
     amendments (including post-effective amendments) and supplements to such
     registration statement or similar such document under applicable Canadian
     securities Laws and the prospectus relating thereto as may be necessary,
     or, in the opinion of the managing underwriter, advisable to keep such
     registration statement or similar such document effective for at least a
     period of six months or, if earlier, until all of such Registrable Shares
     have been disposed of, and to comply with the provisions of the Securities
     Act or the applicable Canadian securities Laws, as the case may be, with
     respect to the sale or other disposition of such Registrable Shares;

          (iii) use its best efforts to register or qualify such Registrable
     Shares under such other securities or "blue sky" Laws of such jurisdictions
     as the holders of the Registrable Shares reasonably request and do any and
     all other acts and things which may be reasonably necessary or advisable to
     enable such holders to consummate the disposition in such jurisdictions of
     such holders' Registrable Shares; provided, however, that the Corporation
     will not be required (A) to qualify generally to do business, subject
     itself to general taxation or consent to general service of process in any
     jurisdiction where it would not otherwise be required to do so but for this
     paragraph (iii), (B) to provide any material undertaking or make any
     changes in its by-laws or certificate of incorporation which the Board of
     Directors determines to be contrary to the best interests of the
     Corporation or (C) to materially modify any of its contractual
     relationships then existing;

          (iv) notify the holders of such Registrable Shares on a timely basis
     of the happening of any event as a result of which a prospectus relating to
     such Registrable Shares, as then in effect, includes 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 not misleading in light
     of the circumstances then existing and, at the request of such holders,
     prepare and furnish without charge to such holders a reasonable number of
     copies of a supplement to or an amendment of such prospectus as may be
     necessary to cause such prospectus, as so supplemented or amended, not to
     include an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading in light of the circumstances then existing;

          (v) furnish without charge to each seller of such Registrable Shares
     and other securities such number of conformed copies of such registration
     statement under the Securities Act, or similar such document under
     applicable Canadian securities Laws and of each such amendment and
     supplement thereto (in each case including all exhibits), such number of
     copies of the prospectus included in such registration statement or similar
     such document (including each preliminary prospectus and any summary
     prospectus), in conformity with the requirements of the Securities Act or
     applicable Canadian securities Laws, as the case may be, such documents
     incorporated by reference in such registration statement or prospectus, and
     such other documents, as such seller may reasonably request in order to
     facilitate the sale or disposition of such Registrable Shares or other
     securities;

          (vi) furnish to each seller of Registrable Shares a signed
     counterpart, addressed to such seller, of (A) an opinion of counsel
     reasonably acceptable to a majority of selling Holders for the Corporation
     in customary form, scope and substance, dated the effective date of such
     registration statement or similar such document (or, if such registration
     includes an underwritten public offering, dated the date of the closing
     under the underwriting agreement), received by the Corporation in
     connection with such registration statement, and (B) "comfort" letters
     signed by the independent public accountants in customary form, scope and
     substance who have issued a report on the Corporation's financial
     statements included in such registration statement or similar such document
     received by the Corporation in connection with such registration statement
     or similar such document;

          (vii) immediately notify each seller of Registrable Shares and other
     securities covered by such registration statement at any time when a
     prospectus relating thereto is required to be delivered under the
     Securities Act or applicable Canadian securities Laws, of the happening of
     any event as a result of which the prospectus included in such registration
     statement, as then in effect, includes an untrue statement of a material
     fact or omits to state any material fact required to be stated therein or
     necessary to make the statements therein not misleading in the light of the
     circumstances then existing or if it is necessary to amend or supplement
     such prospectus to comply with Law, and at the request of any such seller
     prepare and furnish without change to such seller a reasonable number of
     copies of a supplement to or an amendment of such prospectus as may be
     necessary so that, as thereafter delivered to the purchasers of such
     Registrable Shares or other securities, such prospectus shall not include
     an untrue statement of a material fact or omit to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading in the light of the circumstances then existing and shall
     otherwise comply in all material respects with Law and so that such
     prospectus, as amended or supplemented, will comply with Law;

          (viii) otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission, or the applicable rules and
     regulations of any securities regulatory authorities in Canada, and make
     available to its security holders, as soon as reasonably practicable, an
     earnings statement covering the period of at least 12 months, beginning
     with the first month of the first fiscal quarter after the effective date
     of such registration statement, which earnings statement shall satisfy the
     provisions of Section 11(a) of the Securities Act;

          (ix) use its best efforts to list such Registrable Shares on each
     securities exchange on which the Common Shares are then listed, if such
     Registrable Shares are not already so listed and if such listing is then
     permitted under the rules of such exchange, and provide a transfer agent
     and registrar for such Registrable Shares not later than the effective date
     of such registration statement under the Securities Act, or similar such
     document under applicable Canadian securities Laws;

          (x) issue to any underwriter to which any Holder of Registrable Shares
     may sell such Registrable Shares in connection with any such registration
     (and to any direct or indirect transferee of any such underwriter)
     certificates evidencing Common Shares without the legends described in the
     Shareholders Agreement;

          (xi) make every reasonable effort to prevent or obtain the withdrawal
     of any stop order or other order suspending the use of any preliminary or
     final prospectus or suspending any qualification of the Registrable
     Securities at the earliest possible moment;

          (xii) make such representations and warranties to the holders of
     Registrable Securities being registered, and the underwriters or agents, if
     any, in form, substance and scope as are customarily made by issuers in
     secondary underwritten public offerings; and

          (xiii) enter into such customary agreements (including underwriting
     and indemnification agreements) and take all such other actions as the
     holders of at least a majority of any Registrable Securities being sold or
     the managing underwriter or agent, if any, reasonably request in order to
     expedite or facilitate the registration and disposition of such Registrable
     Securities.

The Corporation may require each seller of Registrable Shares as to which any
registration is being effected to furnish the Corporation with such information
regarding such seller and the distribution of such securities as the Corporation
may from time to time reasonably request in writing and as shall be required by
Law or by the Commission or applicable Canadian securities regulatory
authorities, as the case may be, in connection therewith.

           (b) Each holder of the Registrable Shares, upon receipt of any notice
from the Corporation of any event of the kind described in Section 6(a)(iv)
hereof, shall forthwith discontinue disposition of the Registrable Shares
pursuant to the registration statement under the Securities Act, or similar such
document under applicable Canadian securities Laws covering such Registrable
Shares until such holder's receipt of the copies of the supplemented or amended
prospectus contemplated by Section 6(a)(iv) hereof, and, if so directed by the
Corporation, such holder shall deliver to the Corporation all copies, other than
permanent file copies then in such holder's possession, of the prospectus
covering such Registrable Shares at the time of receipt of such notice.

           (c) In connection with the preparation and filing of each
registration statement registering Registrable Shares under the Securities Act,
or similar such document under applicable Canadian securities Laws, the
Corporation will give the Shareholders on whose behalf such Registrable Shares
are to be so registered and their respective counsel and accountants, the
opportunity to review and comment on such registration statement or prospectus,
included therein or filed with the Commission or with any Canadian securities
regulatory authority, and each amendment thereof or supplement thereto, and will
give each of them such access to its books and records and such opportunities to
discuss the business of the Corporation with its officers and the independent
public accountants who have issued a report on its financial statements as shall
be reasonably necessary, in the opinion of such Shareholders and such
underwriters or their respective counsel, to conduct a reasonable investigation
within the meaning of the Securities Act or applicable Canadian securities Laws,
as the case may be.

           (d) In connection with the sale of Registrable Shares registered
pursuant to Section 2 or 3 above, the Corporation's management shall participate
in "road shows" and question and answer meetings with potential purchasers of
such Registrable Shares in connection with offers and sales of such Registrable
Shares.

           (e) It is understood that in any underwritten offering of Registrable
Shares in addition to the Common Shares (the "initial shares") the underwriters
have committed to purchase, the underwriting agreement may grant the
underwriters an option to purchase a number of additional Common Shares (the
"option shares") equal to up to 15% of the initial shares (or such other maximum
amount as the National Association of Securities Dealers, Inc. may then permit),
solely to cover over-allotments. The Common Shares proposed to be sold by the
Corporation and the Holders shall be allocated between initial shares and option
shares as agreed or, in the absence of agreement, pursuant to Section 3(a)(ii).
The number of initial shares and option shares to be sold by selling Holders
shall be allocated pro rata among all such Holders on the basis of the relative
number of Common Shares and other securities each such Holder has requested to
be included in such registration.

           SECTION 7. Indemnification; Contribution. (a) In the event of any
registration of any equity securities of the Corporation under the Securities
Act or applicable Canadian securities Laws, the Corporation will, and hereby
does, indemnify and hold harmless, in the case of any registration statement
filed pursuant to Section 2 or 3 hereof, the seller of any Registrable Shares
covered by such registration statement, its respective affiliates, directors and
officers, each other Person who participates as an underwriter in the offering
or sale of such securities, each officer and director of each such underwriter,
each other Person, if any, who controls such seller or any such underwriter
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, and each Person affiliated with or retained by such seller and who
may be subject to liability under applicable securities Laws, against any
losses, claims, damages, liabilities and expenses, joint or several, to which
they or any of them may become subject under the Securities Act, applicable
Canadian securities Laws or otherwise, insofar as such losses, claims, damages,
liabilities or expenses (or actions or proceedings in respect thereof) arise out
of or are based upon (i) any untrue statement or alleged untrue statement of any
material fact contained in any registration statement under which such
securities were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus included therein, or any amendment or
supplement thereto, or any document incorporated by reference therein, (ii) any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
(iii) any violation by the Corporation of any applicable securities Laws
relating to action or inaction required by the Corporation in connection with
such offer, sale or other disposition under such Laws; provided, however, that
the Corporation shall not be liable in any such case to the extent that any such
loss, claim, damage, liability (or action or proceeding in respect thereof) or
expense arises out of or is based upon (x) an untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement,
any such preliminary prospectus, final prospectus, summary prospectus, amendment
or supplement in reliance upon and in conformity with written information
furnished to the Corporation for use in the preparation thereof by such seller
or underwriter, as the case may be, or (y) an untrue statement or alleged untrue
statement or omission or alleged omission made in any preliminary prospectus but
notified to such seller and underwriter prior to any sale or other disposition
of Registrable Shares and subsequently corrected by the Corporation in any final
prospectus, amendment or supplement made available to such seller or underwriter
but which final prospectus, amendment or supplement was not used by such seller
or underwriter in the sale or other disposition of Registrable Shares that gave
rise to such loss, claim, damage, liability (or action or proceeding in respect
thereof) or expense. This indemnity shall be in addition to any liability the
Corporation may otherwise have. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of such seller or
any such director, officer, underwriter or controlling Person and shall survive
the transfer of such securities by such seller. The Corporation shall reimburse
indemnifiable expenses hereunder as and when incurred.

           (b) The Corporation may require, as a condition to including any
Registrable Shares in any registration statement filed pursuant to Section 2 or
3 hereof, that the Corporation shall have received an undertaking satisfactory
to it from (i) the prospective seller of such securities, to indemnify and hold
harmless (in the same manner and to the same extent as set forth in Section
7(a), except that any such prospective seller shall not in any event be liable
to the Corporation pursuant thereto for an amount in excess of the net proceeds
of the sale of such prospective seller's Registrable Shares so to be sold) the
Corporation, each such underwriter of such securities, each officer and director
of each such underwriter and each other Person, if any, who controls the
Corporation or any such underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, and (ii) each such underwriter
of such securities, to indemnify and hold harmless (in the same manner and to
the same extent as set forth in Section 7(a) above) the Corporation, each
officer and director of the Corporation, each prospective seller, each officer
and director of each prospective seller and each other Person, if any, who
controls the Corporation or any such prospective seller within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, with respect
to any untrue statement in or omission from such registration statement, any
preliminary prospectus, final prospectus or summary prospectus included therein,
or any amendment or supplement thereto, if such untrue statement or omission was
made in reliance upon and in conformity with written information furnished by
such prospective seller or such underwriter, as the case may be, to the
Corporation for use in the preparation of such registration statement,
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of the Corporation or any such director,
officer or controlling Person and shall survive the transfer of such securities
by such seller.

           (c) Promptly after receipt by an indemnified party of notice of the
commencement of any action or proceeding (including any governmental
investigation) involving a claim referred to in either Section 7(a) above or (b)
above, such indemnified party will, if a claim in respect thereof is to be made
against an indemnifying party, give written notice to the latter of the
commencement of such action; provided, however, that the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under the preceding provisions of this
Section 7, except to the extent that the indemnifying party is materially
prejudiced by such failure to give notice. In case any such action is brought
against an indemnified party, the indemnifying party shall be entitled to assume
the defense thereof, jointly with any other indemnifying party similarly
notified, to the extent that it may wish, and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party will not be liable to such indemnified party for
any legal or other expenses subsequently incurred by the indemnified party in
connection with the defense thereof. If, in the indemnified party's reasonable
judgment, a conflict of interest between such indemnified party and indemnifying
parties may exist in respect of such claim, the indemnified party shall be
entitled to participate in the defense thereof and the indemnifying party shall
not be liable for the fees and expenses of more than one counsel for all sellers
of Registrable Shares, or more than one counsel for the underwriters in
connection with any one action or separate but similar or related actions.

           (d) If the indemnification provided for in the foregoing clauses (a),
(b) and (c) of this Section 7 is unavailable to the indemnified parties in
respect of any losses, claims, damages or liabilities referred to therein, then
each indemnifying party shall contribute to the amounts paid or payable by such
indemnified parties as a result of such losses, claims, damages or liabilities
(i) as between the Corporation and the holders of Registrable Shares covered by
a registration statement, on the one hand, and the underwriters, on the other,
in such proportion as is appropriate to reflect the relative benefits received
by the Corporation and such holders, on the one hand, and the underwriters, on
the other, from the offering of the Registrable Shares, or if such allocation is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits but also the relative fault of the Corporation
and such holders, on the one hand, and of the underwriters, on the other, in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations, and (ii) as between the Corporation, on the one hand, and each
holder of Registrable Shares covered by a registration statement, on the other,
in such proportion as is appropriate to reflect the relative fault of the
Corporation and of each such holder in connection with such statements or
omissions, as well as any other relevant equitable considerations. The relative
benefits received by the Corporation and such holders, on the one hand, and the
underwriters, on the other, shall be deemed to be in the same proportion as the
total proceeds from the offering (net of underwriting discounts and commissions
but before deducting expenses) received by the Corporation and such holders bear
to the total underwriting discounts and commissions received by the
underwriters. The relative fault of the Corporation and such holders, on the one
hand, and of the underwriters, on the other, 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 Corporation and such holders or by the
underwriters. The relative fault of the Corporation, on the one hand, and of
each such holder, on the other, shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact
relates to information supplied by such party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

           (e) The Corporation and the holders of Registrable Shares agree that
it would not be just and equitable if contribution pursuant to Section 7(d) were
determined by pro rata allocation (even if the underwriters were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in the next preceding
paragraph. Notwithstanding the provisions of Section 7(d), no holder of
Registrable Shares shall be required to contribute any amount in excess of the
amount by which the total price at which the Registrable Shares of such holder
were offered to the public exceeds the amount of any damages that such holder
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 Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The obligation of the holders of Registrable
Shares to contribute pursuant to this Section 7 is several in the proportion
that the proceeds of the offering received by such holder bears to the total
proceeds of the offering received by all Holders and not joint.

           (f) All sums payable by an indemnifying party to an indemnified party
under this Agreement shall be paid free and clear of all deductions,
withholdings, set-offs or counterclaims whatsoever save only as may be required
by law. If any deductions or withholdings are required by law, the indemnifying
party shall be obliged to pay to the indemnified party such sums as will, after
such deduction or withholding has been made, leave the indemnified party with
the same amount as it would have been entitled to receive in the absence of any
such requirement to make a deduction or withholding.

           (g) If any taxing authority otherwise assesses any tax on any sum
paid by an indemnifying party to an indemnified party under this Agreement other
than a tax in the nature of a net income or franchise tax (hereafter referred to
as a "Tax Assessment"), then the amount so payable shall be grossed up by such
amount as will ensure that after payment of the taxation so charged there shall
be left a sum equal to the amount that would otherwise be payable under this
Agreement. In addition, the indemnified party shall take any action and
institute any proceedings, and give any information and assistance, as the
indemnifying party may reasonably request to dispute, resist, appeal,
compromise, defend, remedy or mitigate the Tax Assessment, in each case on the
basis that the indemnifying party shall indemnify the indemnified party for all
reasonable costs incurred as a result of a request by the indemnifying party.

           (h) An indemnified party shall not admit liability in respect of, or
compromise or settle, a Tax Assessment without the prior written consent of the
indemnifying party (not to be unreasonably withheld or delayed).

           SECTION 8. Underwriting Agreement. Notwithstanding the provisions of
Sections 4, 5, 6, 7 and 8, to the extent that the holders of Registrable Shares
shall enter into an underwriting or similar agreement, which agreement contains
provisions covering one or more issues addressed in such Sections, the
provisions contained in such agreement addressing such issue or issues shall
control; provided, however, that any such agreement to which the Corporation is
not a party shall not be binding upon the Corporation. No Shareholder may
participate in any underwritten registration hereunder unless such holder (a)
agrees to sell such holders' securities on the basis provided in any
underwriting arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
reasonably and customarily required under the terms of such underwriting
arrangements.

           SECTION 9. Information by Holders of Registrable Shares. Each holder
of Registrable Shares shall furnish to the Corporation such written information
regarding such Person and the distribution proposed by such Person as the
Corporation may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification or compliance
referred to in this Agreement.

           SECTION 10. Exchange Act Compliance. The Corporation shall comply
with all of the reporting requirements of the Exchange Act applicable to it and
shall comply with all other public information reporting requirements of the
Commission which are conditions to the availability of Rule 144 for the sale of
the Common Shares. The Corporation shall cooperate with each holder of
Registrable Shares in supplying such information as may be necessary for such
holder to complete and file any information reporting forms presently or
hereafter required by the Commission as a condition to the availability of Rule
144.

           SECTION 11. No Conflict of Rights. Except for the registration rights
granted by the Corporation to the Shareholders under this Agreement, the
Corporation shall not provide to any other holder of its securities rights with
respect to the registration of such securities under Canadian Law, the
Securities Act or any other applicable securities Laws without the prior written
consent of each of the Shareholders holding more than five percent (5%) of
Registrable Securities then outstanding. The Corporation warrants that, other
than as provided herein, it has not granted to any other Person rights with
respect to the registration of any Registrable Securities or any other
securities issued or to be issued by it. The Corporation further warrants that
it is not presently party to any agreement with respect to its securities that
is inconsistent with the rights granted to the Shareholders by this Agreement or
otherwise conflicts with the provisions hereof.

           SECTION 12. Termination. This Agreement shall terminate upon the date
on which there are no longer any Registrable Securities outstanding. The rights
and obligations hereunder of the Shareholders shall terminate at such time when
neither they nor any of their respective Specified Assignees hold Registrable
Securities, provided that the provisions of Section 7 hereof, the rights of any
party hereto with respect to the breach of any provision hereof, and any
obligation accrued as of the date of termination shall survive the termination
of this Agreement.

           SECTION 13. Successors and Assigns. This Agreement shall bind and
inure to the benefit of the Corporation and the Shareholders and, subject to
Section 14 below, their respective successors and assigns.

           SECTION 14. Assignment. Each holder of Registrable Shares may assign
its rights hereunder to any of its Permitted Transferees or any Specified
Assignee; provided, however, that such Permitted Transferees or Specified
Assignee, as the case may be, shall, as a condition to the effectiveness of such
assignment, be required to execute a counterpart to this Agreement agreeing to
be treated as a Shareholder holding Registrable Shares whereupon such Specified
Assignee shall have the benefits of, and shall be subject to the restrictions
contained in, this Agreement as if such Specified Assignee or Permitted
Transferee had originally been a party hereto.

           SECTION 15. Entire Agreement. This Agreement and the New Shareholders
Agreement constitute the entire agreement of the parties hereto with respect to
the subject matter hereof and thereof and supersede all prior agreements and
undertakings, both written and oral, between the parties with respect to the
subject matter hereof and thereof. For the sake of clarity, the parties
acknowledge that the BCE Agreement, and any other agreement between BCE Inc.and
the Corporation with respect to the matters governed by the BCE Agreement shall
have no further force and effect and shall be superseded in their entirety by
this Agreement.

           SECTION 16. Notices. All notices, requests, claims, demands and other
communications hereunder shall be in writing and shall be given or made (and
shall be deemed to have been duly given or made upon receipt) by delivery in
person, by courier service, by facsimile, or by registered or certified mail
(postage prepaid, return receipt requested) to the parties at the addresses
specified in Section 6.03 of the Shareholders Agreement (or at such other
address for a party as shall be specified in a notice given in accordance with
this Section 16).

           SECTION 17. Modifications; Amendments; Waivers. This Agreement may
not be amended or modified, except by an instrument in writing signed by, or on
behalf of, the Corporation and Shareholders representing 75% of the Registrable
Securities.

           SECTION 18. Counterparts; Facsimile Signatures. This Agreement may be
executed and delivered in one or more counterparts (including by telecopy), and
by the different parties hereto in separate counterparts, each of which when
executed shall be deemed to be an original but all of which taken together shall
constitute one and the same agreement.

           SECTION 19. Headings. The descriptive headings contained in this
Agreement are for convenience of reference only and shall not affect in any way
the meaning or interpretation of this Agreement.

           SECTION 20. Severability; Governing Law. If any term or other
provision of this Agreement is invalid, illegal or incapable of being enforced
by any Law, governmental regulation or public policy, all other terms and
provisions of this Agreement shall nevertheless remain in full force and effect
as long as the economic or legal substance of the transactions contemplated
hereby is not affected in any manner materially adverse to any party. Upon such
determination that any term or other provision is invalid, illegal or incapable
of being enforced, the parties hereto shall negotiate in good faith to modify
this Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner in order that the transactions contemplated
hereby are consummated as originally contemplated to the greatest extent
possible. This Agreement shall be governed by, and construed in accordance with,
the laws of the State of New York applicable to contracts executed in and to be
performed in that State without regard to conflicts of law.

           SECTION 21. Waiver of Jury Trial. Each of the parties hereto
irrevocably and unconditionally waives trial by jury in any legal action or
proceeding relating to this Agreement, the transactions contemplated hereby and
for any counterclaim therein.

           SECTION 22. Dispute Resolution. The parties agree that any
controversy, claim or dispute arising out of or relating to or in connection
with this Agreement, including, without limitation, any dispute regarding its
breach, termination, enforceability or validity hereof (each, a "Dispute")
should be regarded as a business problem to be resolved promptly through
business-oriented negotiations before resorting to arbitration pursuant to
Section 22. The parties therefore agree to attempt in good faith to resolve any
Dispute promptly by negotiation between the executives of the parties who have
authority to settle the Dispute. Such negotiations shall commence upon the
mailing of a notice (the "Dispute Notice") from the appropriate executive of the
requesting party to an appropriate executive of the responding party. If the
Dispute has not been resolved by these Persons within forty-five (45) days of
the date of the Dispute Notice, unless the parties agree in writing to a longer
period, the Dispute shall be referred to the chief executive officer of each of
the Shareholders and the Company, as the case may be, party to such Dispute, for
discussion and negotiation among them. In the event the Dispute has still not
been resolved by negotiation within forty-five (45) days of such referral, then
such Dispute shall be settled pursuant to binding arbitration pursuant to
Section 23. All negotiations pursuant to this Section 22 shall be confidential
and shall be treated as compromise and settlement negotiations for purposes of
applicable rules of evidence and shall not be used for, or admitted in, any
arbitration or court proceedings under this Agreement.

           SECTION 23. Arbitration. Any Dispute that has not been resolved
pursuant to Section 22 shall be finally settled by binding arbitration in The
City of New York, New York County, before a panel of three arbitrators. The
arbitration shall be administered by the International Court of Arbitration of
the International Chamber of Commerce (the "ICC") under its Rules of Arbitration
as in effect at the time of this Agreement, except as they may be modified
herein or by agreement of the parties and shall be conducted in the English
language. Each party shall nominate one arbitrator, obtain its nominee's
acceptance of such nomination, and deliver written notification of such
nomination and acceptance to the other party within thirty (30) days after
delivery of the request for arbitration. In the event a party fails to nominate
an arbitrator or deliver notification of such nomination to the other party
within this time period, upon request of any party, such arbitrator shall
instead be appointed by the ICC within thirty (30) days of receiving such
request. In the event there are two Shareholders, or one Shareholder and the
Corporation are parties to the dispute, the two arbitrators nominated in
accordance with the above provisions shall nominate the third arbitrator, obtain
the nominee's acceptance of such nomination and notify the parties in writing of
such nomination and acceptance within thirty days of their nomination. If the
first two nominated arbitrators fail to nominate a third arbitrator or notify
the parties of that nomination within this time period, then, upon request of
either party, the third arbitrator shall be appointed by the ICC within thirty
(30) days of receiving such request. Nonetheless, in no event shall any such
arbitrator nominated by the other arbitrators be a resident in, or a domicile
of, any country in which a Shareholder or the Corporation is domiciled or has
its principal place of business. In the event that each of the Shareholders and
the Corporation are parties to the Dispute, each shall be entitled to nominate
an arbitrator in the manner and time period referred to above. In the event a
party fails to nominate an arbitrator or deliver notification of such nomination
to the other parties within this time period, upon request of any party, such
arbitrator shall instead be appointed by the ICC within thirty (30) days of
receiving such request. The arbitrators appointed in accordance with the above
provisions shall mutually agree to designate one of them to act as chair within
thirty (30) days of their appointment. For the sake of clarity, it is expressly
understood that the function of such chair is administrative only and shall not
signify that such chair has greater or different powers as arbitrator from the
other arbitrators. In the event that the arbitrators nominated in accordance
with the above provisions fail to agree upon the selection of a chair within
this time period, upon request of any party, the chair shall instead be
designated by the ICC within thirty days of receiving such request. The award of
the arbitrators shall be final and binding upon the parties, and shall not be
subject to any appeal or review. The parties agree to submit to the
non-exclusive personal jurisdiction of the federal and state courts sitting in
The City of New York, New York for the purpose of enforcing this agreement to
arbitrate.

           (a) No provision of, nor the exercise of any rights under, this
Section 23 shall limit the right of any party to request and obtain from a court
of competent jurisdiction in The City of New York (which shall have exclusive
jurisdiction for purposes of this Section 23(b)) before, during or after the
pendency of any arbitration, provisional or ancillary remedies and relief
including, but not limited to, injunctive or mandatory relief or the appointment
of a receiver. The institution and maintenance of an action or judicial
proceeding for, or pursuit of, provisional or ancillary remedies shall not
constitute a waiver of the right of any party, even if it is the plaintiff, to
submit the dispute to arbitration if such party would otherwise have such right.
Each of the parties hereby submits unconditionally to the exclusive jurisdiction
of the state and federal courts located in The City of New York, County of New
York for purposes of this provision, waives objection to the venue of any
proceeding in any such court or that any such court provides an inconvenient
forum and consents to the service of process upon it in connection with any
proceeding instituted under this Section 23(b) in the same manner as provided
for the giving of notice hereunder.

           (b) Judgment upon the award rendered may be entered in any court
having jurisdiction. The parties hereby expressly consent to the nonexclusive
jurisdiction of the state and federal courts situated in The City of New York,
County of New York for this purpose and waive objection to the venue of any
proceeding in such court or that such court provides an inconvenient forum.

           2.1. BCE Tax Indemnification. (a) Subject to the terms and conditions
hereof, BCE agrees to indemnify each Indemnitee against, and hold each of them
harmless from, on an After-Tax Basis, any and all Losses incurred by such
Indemnitee, or by BCI, Newco, Surviving Entity or any Contributed Company or any
Subsidiary or Minority Investee (as defined in the Shareholders Agreement) of
any of them, by reason of any Taxes payable, or any adverse Tax consequences
arising, as a result of the consummation of the Consolidation (including,
without limitation, by reason of any breach of any representation or covenant
given by BCE, BCI, Newco, Surviving Entity or any Contributed Company or any
action taken or omitted by BCE, BCI, Newco, Surviving Entity or any Contributed
Company, or any Subsidiary or Minority Investee; provided, however, that
"Losses" shall not include any continuing adverse Tax consequences with respect
to the ongoing activities (including payment of dividends) of BCI or Surviving
Entity and its subsidiaries arising as a result of the consummation of the
Consolidation.

           (b) In the case of any Loss incurred by BCI, Newco, Surviving Entity
or any Contributed Company, or any Subsidiary or any Minority Investee of any of
them, referred to in Section 2.1(a), each such Indemnitee shall be deemed to
have incurred a Loss equal to the product of (i) the Tax Liabilities and (ii)
the percentage of Surviving Entity's Outstanding common shares held by such
Indemnitee immediately following the Consolidation (the "Ownership Percentage"),
and, if applicable, (iii) the percentage beneficial interest held by Surviving
Entity in the entity incurring the Loss. Such Losses shall be deemed to have
been incurred when, and such indemnification shall be paid not more than ___
days following, the date on which the Losses are paid or become due and payable.

           (c) Notwithstanding anything to the contrary set forth in this
Agreement, in the case of any loss incurred by BCI, Newco, Surviving Entity or
any Contributed Company, or any Subsidiary or Minority Investee of any of them,
referred to in Section 2.1(a), BCE shall not be required to indemnify the
Indemnitees pursuant to Section 2.1 if and to the extent that BCE contributes,
or causes to be contributed, to the capital of BCI, Newco, Surviving Entity or
any Contributed Company, or the applicable Subsidiary or Minority Investee, in
cash, or otherwise satisfies, on an After-Tax Basis, all or any part of the Tax
Liabilities (it being understood that BCE shall have no obligation to do so and
that if BCE does so, it shall not be entitled to receive any consideration from
BCI, Newco, Surviving Entity or any Contributed Company, or the applicable
Subsidiary or Minority Investee, whether in capital stock or otherwise, nor
shall BCE have any right of contribution from BCI, Newco, Surviving Entity or
any Contributed Company, or the applicable Subsidiary or Minority Investee in
respect of the satisfaction of such Tax Liabilities).

           (d) It is understood and agreed that BCE shall not have any
obligation to indemnify the Indemnitees in respect of Taxes payable, or any
adverse Tax consequences arising as a result of any change in the Tax domicile
of BCI, Newco or Surviving Entity following the Consolidation Date.

           2.2. Contests With Respect to Indemnitees.

           (a) If a Taxing authority proposes in writing, on audit or otherwise,
to assert a claim against an Indemnitee for which BCE is required to indemnify
an Indemnitee pursuant to Section 2.1 hereof, such Indemnitee shall notify BCE
in writing within ten (10) Business Days of the receipt of such proposal and
such Indemnitee shall forebear, for at least thirty (30) days (or such lesser
period as is permitted by law), payment of any Taxes asserted to be payable as a
result of such proposed adjustment.

           (b) If BCE shall request in writing within ten (10) Business Days
after such Indemnitee's notice pursuant to Section 2.2(a) above that the
proposed adjustment be contested and shall furnish to such Indemnitee, at BCE's
sole expense, a written opinion of counsel to BCE, in form and in substance
reasonably satisfactory to such Indemnitee, to the effect that the position to
be put forth by such Indemnitee should prevail, such Indemnitee shall, in good
faith, at BCE's sole expense, contest the proposed adjustment and shall make a
good faith effort to consult with BCE in contesting such proposed adjustment and
apprise them of the progress thereof; provided that such Indemnitee shall not be
required to contest the proposed adjustment beyond the first level of judicial
proceedings following the highest level of administrative proceedings and
provided further that such Indemnitee shall not be required to take any action
pursuant to this Section 2.2(b) unless: (i) BCE shall have agreed to pay such
Indemnitee on demand, on an After-Tax Basis, all costs and expenses, if any,
that such Indemnitee incurs in contesting such proposed adjustment (including,
without limitation, reasonable legal and accounting fees, disbursements,
penalties, interest and additions to Tax related to such proposed adjustment)
and shall have provided security reasonably acceptable to such Indemnitee for
the payment of such costs and expenses, and (ii) BCE shall have acknowledged and
agreed in writing to its indemnity obligation with respect to such proposed
claim pursuant to this Agreement.

           (c) An Indemnitee may at any time decline to take any further action
with respect to a proposed adjustment, including settlement or compromise
thereof; provided that if BCE has requested in writing and in accordance with
Section 2.2(b) hereof that such Indemnitee contest any proposed adjustment
pursuant to this Agreement, such Indemnitee shall notify BCE in writing that
such Indemnitee has determined not to take any further action with respect to
such proposed adjustment and agrees to waive its right to any indemnification
payment that would otherwise be payable by BCE pursuant to this Agreement in
respect of such adjustment.

           (d) If BCE shall have requested in writing that an Indemnitee contest
any proposed adjustment as above provided and shall have duly complied with all
of the terms of this Section 2.2, demand for payment of any amounts due and
payable hereunder may be made no earlier than upon a Final Determination of the
Liabilities of such Indemnitee for the Loss asserted to be payable as a result
of such proposed adjustment. For the purposes of this Agreement, the term "Final
Determination" means (i) a closing agreement entered into under Section 7121 of
the U.S. Internal Revenue Code, or any other settlement agreement entered into
in connection with an administrative proceeding (consented to by BCE, which
consent shall not be unreasonably withheld) or (ii) a final, non-appealable
judgment by the first level of judicial proceedings following the highest level
of administrative proceedings or, if BCE agrees in writing not to pursue the
matter in such a court, the highest level of administrative proceedings shall
have been completed and payment shall be made within five (5) days of demand
therefor.

           (e) All amounts payable by BCE pursuant to Section 2.1 shall be paid
in the legal tender of the United States of America.

           3. BCI's Indemnification. (a) BCI hereby agrees to indemnify each
Indemnitee (the "BCI Indemnification") against, and hold it harmless from, on an
After-Tax Basis, all Losses incurred by such Indemnitee in respect of all BCI
Liabilities (other than any such BCI Liabilities with respect to which a fully
funded cash reserve in the amount of the Defeasance Amount was established by
BCI prior to the Consolidation, which Liabilities are paid from such cash
reserve); provided, however, that the BCI Indemnification with respect to BCI
Liabilities, other than BCI Liabilities subject to indemnification under Section
2 hereof, shall terminate and BCI shall have no further indemnification
obligation to any party in respect thereof as of the date that is five (5) years
following the Consolidation Date, except with respect to any claim in respect
thereof by any party which is made prior to the end of such period, in which
event indemnification shall survive until the final resolution of such matter.

           (b) For purposes of Section 3(a) above, each Indemnitee shall be
deemed to have incurred Losses equal to the product of (i) the amount of the BCI
Liabilities and (ii) the Ownership Percentage of such Indemnitee. Such Losses
shall be deemed to have been incurred when the applicable BCI Liabilities have
been paid or become due and payable.

           (c) It is expressly understood and agreed that, in connection with a
transfer of (i) Shares of Newco, (ii) BCI Shares or, (iii) Shares of Surviving
Entity ("Surviving Entity Shares") by Telmex, SBCI or their respective Specified
Assignees, the transferor may, in its sole discretion, retain the rights under
the BCI Indemnification set forth in this Section 3, in which case (1) the
transferee shall not be deemed an Indemnitee under this Section 3 and (2) the
transferor shall be deemed, for purposes of this Section 3 and Section 4, to
continue to own the transferred Shares of Newco, BCI Shares, or Surviving Entity
Shares (in each case, to the extent such rights are so retained by the
transferor).

           4. Payment

           4.1. Form of Payment. Any obligations due from BCI to the Indemnitees
under Section 3 hereof shall be satisfied by delivery to the Indemnitees, within
ten (10) Business Days of the incurrence (as provided in Section 3(b)) by the
Indemnitees of any Losses indemnifiable pursuant to the terms of Section 3 of
this Agreement[, at the sole option of BCI] of [(i) cash in the full amount of
such Losses or (ii)](1) Surviving Entity Shares, as provided in Section 4.2
below; provided, however, that if any indemnification payable hereunder by BCI
would increase the aggregate percentage ownership of the outstanding common
equity of Surviving Entity held by the Indemnitees to more than 99% (the
"Indemnification Threshold"), then Surviving Entity shall issue to the
Indemnitees such number of Surviving Entity Shares as to increase such ownership
to the Indemnification Threshold, and the remaining portion of BCI's
indemnification obligation shall be paid by BCE to the Indemnitees in legal
tender of the United States of America.

--------
1 The parties agree to discuss.

           4.2. Issuance of Shares. (a) The aggregate number of Surviving Entity
Shares to be issued pursuant to Section 4.1 arising by reason of a Loss in
respect of BCI Liabilities shall be determined as follows:

           [x+z divided by y+z] multiplied by [V minus the amount of
           the BCI Liabilities] = [x divided by y] multiplied by V

          In the foregoing formula,

          x = number of Surviving Entity Shares held by the Indemnitees
          immediately following the Consolidation

          y = number of Surviving Entity Shares outstanding immediately
          following the Consolidation

          z = number of Surviving Entity Shares to be issued

          V = total equity value of Surviving Entity immediately following the
          Consolidation, determined as the product of (1) the number of
          Surviving Entity Shares outstanding immediately following the
          Consolidation (adjusted to give effect to any differences in the
          capitalization of BCI and Surviving Entity) and (2) the average of the
          closing prices of BCI Shares on the [exchange] during the thirty (30)
          trading days ending on the __ trading day preceding the Consolidation
          Date).

For purposes of determining the aggregate number of Surviving Entity Shares to
be issued pursuant to this Section 4.2(a), the amount of the BCI Liabilities
shall be (I) increased to the extent of any increase in cash Taxes actually
payable by [BCI or] Surviving Entity in the taxable year in which the BCI
Liabilities are paid arising from the receipt of any payments made pursuant to
Section 4.2(d) or otherwise in connection with the BCI Liabilities (the "Current
Cash Tax Cost") and (II) reduced (but not below zero) to the extent of any
reduction in cash Taxes actually payable by [BCI or] Surviving Entity in the
taxable year in which the BCI Liabilities is paid arising from the payment of
the BCI Liabilities (the "Current Cash Tax Benefit"). In computing the amount of
any Current Cash Tax Cost or any Current Cash Tax Benefit, [BCI or] Surviving
Entity shall be deemed to recognize all other items of income, gain, loss,
deduction or credit before recognizing any item with respect to the BCI
Liabilities.

           (b) The number of Surviving Entity Shares issuable pursuant to
Section 4.2(a) shall be increased so as to ensure that the Indemnitees are
indemnified on an After-Tax Basis.

           (c) The number of Surviving Entity Shares to be issued to each
Indemnitee as an indemnification payment shall equal the aggregate number of
Surviving Entity Shares issuable in respect of a Loss multiplied by such
Indemnitee's percentage ownership of the issued and outstanding Surviving Entity
Shares.

           (d) Notwithstanding anything to the contrary set forth in this
Agreement, BCI shall not be required to indemnify the Indemnitees pursuant to
Section 3 if and to the extent that BCE contributes, or causes to be
contributed, to the capital of Surviving Entity, in cash, or otherwise
satisfies, on an After-Tax Basis, all or any part of the BCI Liabilities (it
being understood that, except as provided in Section 4.1 hereof, BCE shall have
no obligation to do so and that if BCE does so, it shall not be entitled to
receive any consideration from Surviving Entity whether in capital stock or
otherwise, nor shall BCE have any right of contribution from Surviving Entity in
respect of the satisfaction of such BCI Liabilities).

           4.3. Dispute Procedures for Arithmetic Calculations. Any dispute
raised by any party (the "Disputing Party") as to the arithmetic calculations
made pursuant to Section 4.2 hereof shall be resolved by an independent
internationally recognized accounting firm, other than _________ and _________,
mutually acceptable to each of Telmex, SBCI, BCE and BCI (or Surviving Entity).
In the event that the parties are unable to agree on an independent accounting
firm within ten (10) Business Days of any dispute arising as to any arithmetic
calculations under Section 4.2 hereof, then the accounting firm designated
pursuant to this Section 4.3 shall be ___________. Each of the parties hereto
shall use its reasonable efforts to cause the accounting firm to render a
determination concerning the disputed calculations made pursuant to Section 4.2
hereof within twenty (20) Business Days following submission of such dispute to
the accounting firm. The report of the independent accounting firm shall be
final, binding and conclusive on each of the parties hereto and all Indemnitees.
The fees and expenses of such accounting firm shall be borne by BCI or Surviving
Entity, as the case may be ; provided, however, that if the report of such
independent accounting firm concludes that the final arithmetic calculation is
within 10% of the initial arithmetic calculation, the fees and expenses of the
accounting firm shall be borne by the Disputing Party.

           4.4. Treatment of Indemnification Payments. The parties hereto agree
to treat all indemnification payments made ursuant to this Section 4 as
adjustments to the Consolidation consideration, unless otherwise required by Law
or Taxing authority.

           5. Undertaking. If Surviving Entity Shares are required to be
delivered to any Indemnitee pursuant to the terms of this Agreement, BCE and the
other parties hereto, each in its capacity as a direct or indirect shareholder
of BCI or Surviving Entity, as the case may be, shall take (and shall cause
their respective Specified Assignees to take) all necessary actions, including
exercising the rights of such party (or such Specified Assignees) as a
shareholder in BCI or Surviving Entity to the fullest extent permitted by Law,
in order to ensure BCI's and Surviving Entity's compliance with its obligations
hereunder. Without limiting the generality of the foregoing, the obligations of
any such party shall include, if necessary, (i) proposing to the Directors of
Surviving Entity an increase of the capital of Surviving Entity and voting
affirmatively for such capital increase at any meeting of shareholders of
Surviving Entity called for that purpose; and (ii) seeking or causing the
resignation or arranging for a meeting of shareholders or BCI or Surviving
Entity, as the case may be, for the removal, of any Director of BCI or Surviving
Entity who failed to vote in favor of any action required to be taken by BCI or
Surviving Entity to comply with any of its obligations hereunder and, further,
the election of new Directors of BCI or Surviving Entity in order to ensure
BCI's or Surviving Entity's compliance, and voting affirmatively for such
removal and election at any such meeting.

           6. Books and Records/Notice

           6.1. Right to Books and Records; Delivery of Supporting Calculations.
Subject to reasonable and customary confidentiality undertakings:

           (a) Each Indemnitee, including its authorized representatives, shall
have reasonable access to (including the right to make copies of) such books and
records and other materials of BCI or Surviving Entity, as the case may be, in
order to confirm that no BCI Liabilities have been paid or are due.

           (b) Each Indemnitee agrees, upon the request and at the expense of
BCE, that the amount of any Loss due to such Indemnitee shall be verified by a
public accounting firm selected by such Indemnitee and reasonably acceptable to
BCE.

           6.2. Notice of Obligations. Within ten (10) days of being notified
that BCI Liabilities are payable, or upon learning of a contingent liability for
BCI Liabilities, BCI or Surviving Entity, as the case may be, shall advise in
writing each Indemnitee and keep each Indemnitee apprised in writing (in
reasonable detail) of the progress of the resolution of such demand.

           6.3. Late Payments. Any amounts not paid when due and payable under
this Agreement shall bear interest from the date due to the date paid at the
prime rate of [BANK] as in effect from time to time during such period.

           7. Miscellaneous

           7.1. Notices. All notices, requests, claims, demands and other
communications hereunder shall be in writing and shall be given or made (and

person, by courier service, by telecopy, or by registered or certified mail
(postage prepaid, return receipt requested) to the respective parties at the

           7.2. Headings. The descriptive headings contained in this Agreement
are for convenience of reference only and shall not affect in any way the
meaning or interpretation of this Agreement.

           7.3. Severability. If any term or other provision of this Agreement
is invalid, illegal or incapable of being enforced by any Law, governmental
regulation or public policy, all other terms and provisions of this Agreement
shall nevertheless remain in full force and effect as long as the economic or
legal substance of the transactions contemplated hereby is not affected in any
manner materially adverse to any party. Upon such determination by a
Governmental Authority that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith to
modify this Agreement so as to effect the original intent of the parties as
closely as possible in an acceptable manner in order that the transactions
contemplated hereby are consummated as originally contemplated to the greatest
extent possible.

           7.4. Entire Agreement. This Agreement constitutes the entire
agreement of the parties hereto with respect to the subject matter hereof and
thereof and supersedes all prior agreements and undertakings, both written and
oral, between or among the parties with respect to the subject matter hereof and
thereof.

           7.5. Assignment. This Agreement shall not be assigned without the
express written consent of the parties (which consent may be granted or withheld
in the sole discretion of any party), except that any party hereto may assign
its rights (but not its obligations) hereunder to an Affiliate or Specified
Assignee of such party; provided, however, that any such assignment shall not
relieve the assigning party of its obligations hereunder.

           7.6. No Third Party Beneficiaries. Except as otherwise provided
herein with respect to the indemnification of Indemnitees, this Agreement shall
be binding upon and inure solely to the benefit of the parties hereto and
nothing herein, express or implied, is intended to or shall confer upon any
other person or entity, any legal or equitable right, benefit or remedy of any
nature whatsoever under or by reason of this Agreement.

           7.7. Amendment. This Agreement may not be amended or modified, except
by an instrument in writing signed by, or on behalf of, each of the parties and
each 10% Shareholder to which indemnification rights are assigned in accordance
herewith.

           7.8. Governing Law. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York applicable to
contracts executed in and to be performed in that State.

           7.9. Counterparts. This Agreement may be executed and delivered in
one or more counterparts, and by the different parties hereto in separate
counterparts, each of which when executed and shall be deemed to be an original,
all of which taken together shall constitute one and the same Agreement.

           7.10. Specific Performance. The parties hereto agree that irreparable
damage would occur in the event any provision of this Agreement was not
performed in accordance with the terms hereof and that the parties shall be
entitled to specific performance of the terms hereof, in addition to any other
remedy at law or in equity.

           8. Arbitration/Dispute Resolution Procedures.

           8.1 Arbitration. (a) Any Dispute that has not been resolved pursuant
to the terms of this Agreement shall be finally settled by binding arbitration
in The City of New York, New York County, before a panel of three arbitrators.
The arbitration shall be administered by the International Court of Arbitration
of the International Chamber of Commerce (the "ICC") under its Rules of
Arbitration as in effect at the time of this Agreement, except as they may be
modified herein by agreement of the parties and shall be conducted in the
English language. Each party shall nominate one arbitrator, obtain its nominee's
acceptance of such nomination, and deliver written notification of such
nomination and acceptance to the other party within thirty (30) days after
delivery of the request for arbitration. In the event a party fails to nominate
an arbitrator or deliver notification of such nomination to the other party
within this time period, upon request of any party, such arbitrator shall
instead be appointed by the ICC within thirty (30) days of receiving such
request. In the event there are two parties to this Agreement who are parties to
the dispute, the two arbitrators nominated in accordance with the above
provisions shall nominate the third arbitrator, obtain the nominee's acceptance
of such nomination and notify the parties in writing of such nomination and
acceptance within thirty days of their nomination. If the first two nominated
arbitrators fail to nominate a third arbitrator or notify the parties of that
nomination within this time period, then, upon request of either party, the
third arbitrator shall be appointed by the ICC within thirty (30) days of
receiving such request. Nonetheless, in no event shall any such arbitrator
nominated by the other arbitrators be a resident in, or a domicile of, any
country in which a shareholder is domiciled or has its principal place of
business. In the event that each of BCI, Surviving Entity and/or BCE (considered
together), Telmex and SBCI are parties to the Dispute, each shall be entitled to
nominate an arbitrator in the manner and time period referred to above. In the
event a party fails to nominate an arbitrator or deliver notification of such
nomination to the other parties within this time period, upon request of any
party, such arbitrator shall instead be appointed by the ICC within thirty (30)
days of receiving such request. The three arbitrators appointed in accordance
with the above provisions shall mutually agree to designate one of them to act
as chair within thirty days of their appointment. For the sake of clarity, it is
expressly understood that the function of such chair is administrative only and
shall not signify that such chair has greater or different powers as arbitrator
from the other arbitrators. In the event that the arbitrators nominated in
accordance with the above provisions fail to agree upon the selection of a chair
within this time period, upon request of any party, the chair shall instead be
designated by the ICC within thirty days of receiving such request. The award of
the arbitrators shall be final and binding upon the parties, and shall not be
subject to any appeal or review. The parties agree to submit to the
non-exclusive personal jurisdiction of the federal and state courts sitting in
The City of New York, New York for the purpose of enforcing this agreement to
arbitrate.

           (b) No provision of, nor the exercise of any rights under, this
Section 8.1 shall limit the right of any party to request and obtain from a
court of competent jurisdiction in The City of New York (which shall have
exclusive jurisdiction for purposes of this Section 8.1(b)) before, during or
after the pendency of any arbitration, provisional or ancillary remedies and
relief including, but not limited to, injunctive or mandatory relief or the
appointment of a receiver. The institution and maintenance of an action or
judicial proceeding for, or pursuit of, provisional or ancillary remedies shall
not constitute a waiver of the right of any party, even if it is the plaintiff,
to submit the dispute to arbitration if such party would otherwise have such
right. Each of the parties hereby submits unconditionally to the exclusive
jurisdiction of the state and federal courts located in The City of New York,
County of New York for purposes of this provision, waives objection to the venue
of any proceeding in any such court or that any such court provides an
inconvenient forum and consents to the service of process upon it in connection
with any proceeding instituted under this Section 8.1(b) in the same manner as
provided for the giving of notice hereunder.

           (c) Judgment upon the award rendered may be entered in any court
having jurisdiction. The parties hereby expressly consent to the nonexclusive
jurisdiction of the state and federal courts situated in The City of New York,
County of New York for this purpose and waive objection to the venue of any
proceeding in such court or that such court provides an inconvenient forum.

           (d) Each of the parties participating in an arbitration pursuant to
the terms of this Agreement shall, subject to the award of the arbitrators, pay
an equal share of the arbitrators' fees. The arbitrators shall have the power to
award recovery of all costs (including reasonable attorneys' fees,
administrative fees, arbitrators' fees and court costs) to the prevailing party.

           8.2 Waiver of Jury Trial. Each of the parties hereto irrevocably and
unconditionally waives trial by jury in any legal action or proceeding relating
to this Agreement.

           8.3 Service of Process. Each of:

           (a) BCI hereby irrevocably designates CT Corporation, with offices
situated at present at 1633 Broadway, New York, New York 10019;

           (b) [Surviving Entity] hereby irrevocably designates CT Corporation,
with offices situated at present at 1633 Broadway, New York, New York 10019;

           (c) BCE hereby irrevocably designates CT Corporation, with offices
situated at present at 1633 Broadway, New York, New York 10019;

           (d) Telmex hereby irrevocably designates CT Corporation, with offices
situated at present at 1633 Broadway, New York, New York 10019; and

           (e) SBCI hereby irrevocably designates CT Corporation, with offices
situated at present at 1633 Broadway, New York, New York 10019;

as its authorized agent, respectively, to accept and acknowledge on its behalf
service of any process which may be served in any suit, action or proceeding in
New York.

                            ALTERNATE TAX STRUCTURES

Part 1: Danish Structure

                  Each company that is located in a jurisdiction that is treated
as a tax haven for purposes of the Neutral Provisions (a "Tax Haven Company")
will be replaced by a Danish company. The Danish company shall in all cases be a
company that is formed in Denmark and is a tax resident of Denmark; furthermore,
in order to reasonably facilitate SBCI's ability to recognize foreign tax
credits, the Danish company will not be incorporated as an Aktieselskab unless
the decision not to use an Aktieselskab causes adverse tax consequences,
directly or indirectly, for the Company or the shareholders. The Company and the
two new subholding companies created to hold the Comcel and Brazilian CLEC
operations would be included among the companies that would be replaced by a
Danish company. The method of the transfer would generally be as follows
(subject to advice of Danish counsel to minimize, if possible, any adverse tax
consequences of moving the company to Denmark):

                  (i) the shareholder(s) of the Tax Haven Company would form a
new Danish company;

                  (ii) the shareholder(s) of the Tax Haven Company would
transfer its (their) shares of the Tax Haven Company to the new Danish company;
and

                  (iii) the Tax Haven Company would liquidate or wind up into
its parent Danish company.

Part II:  Netherlands-Danish Structure

                  Each Tax Haven Company (including the Company and the new
subholding companies located in tax haven jurisdictions) will be replaced by a
company that is formed in the Netherlands and a tax resident of the Netherlands
(unless changes have been made to the Danish holding period requirements so that
it would be advantageous for all lower tier holding companies to be Danish
companies, in which case the companies other than the Company would be replaced
by Danish companies in accordance with Part I, above). In order to reasonably
facilitate SBCI's ability to recognize foreign tax credits, the Netherlands
company will not be incorporated as a Naamloze Vennootschap unless the decision
not to use a Naamloze Vennootschap causes adverse tax consequences, directly or
indirectly, for the Company or the shareholders. The method of the transfer
would generally be as follows (subject to advice of Netherlands counsel to
minimize, if possible, the incidence of capital tax on the transfers and any
other adverse tax consequences of the change of structure):

                  (i) the shareholder(s) of the Tax Haven Company would form a
new Netherlands company;

                  (ii) the shareholder(s) of the Tax Haven Company would
transfer its (their) shares of the Tax Haven Company to the new Netherlands
company; and

                  (iii) the Tax Haven Company would liquidate or wind up into
its parent Netherlands company.

         Upon the occurrence of the BCI BVI V Redemption Condition (as defined

and outstanding preference shares of BCI BVI V Limited (the "BCI BVI V
Preference Shares") at the time of the occurrence of the BCI BVI V Redemption

certificates representing such BCI BVI V Preference Shares, and (iii) specifying
the consideration to be paid to each of BCI Investments and AM Latin America and

redeem such shares.

         For purposes of the foregoing, "BCI BVI V Redemption Condition" means
the occurrence of any of the following: (i) receipt by the Company, BCI BVI V

such agency or any successor regulation thereto which effectively permits the
Company or any future shareholder or shareholders holding voting common shares
of BCI BVI V Limited (the "BCI BVI V Common Shares") to Control BCI BVI V
Limited, (ii) a change in applicable Brazilian regulations or laws that results
in such approval no longer being required in the opinion of the Board of
Directors of BCI BVI V Limited, (iii) the delivery to BCI BVI V Limited of a
notice signed by, or on behalf of, the shareholder or shareholders holding a
majority of BCI BVI V Common Shares stating that, in its or their reasonable
judgment, the redemption of 100% of the BCI BVI V Preference Shares as
contemplated herein without ANATEL's approval will not result in a violation of
Resolution 101 of such agency or any successor regulation thereto, (iv) the Sale
of any BCI BVI V Preference Shares by BCI Investments or AM Latin America, as
the case may be (or by any Permitted Transferee of BCI Investments or AM Latin
