<PAGE>   17
                  SECTION 2.02. Loans and Borrowings.

                  (a) Obligations of Lenders. Each Loan shall be made as part of
a Borrowing consisting of Loans made by the Lenders ratably in accordance with
their respective Commitments. The failure of any Lender to make any Loan
required to be made by it shall not relieve any other Lender of its obligations
hereunder; provided that the Commitments of the Lenders are several and no
Lender shall be responsible for any other Lender's failure to make Loans as
required.

                  (b) Type of Loans. The initial Borrowing shall comprise only
Eurodollar Loans. Each Lender at its option may make any Loan by causing any
domestic or foreign branch or Affiliate of such Lender to make such Loan;
provided that any exercise of such option shall not affect the obligation of
each Borrower to repay such Loan in accordance with the terms of this Agreement.

                  (c) Amount of Loans. The Loans shall be part of a single
Borrowing on the Disbursement Date, and each Loan shall be in an amount of no
less than $1,000,000 and in an amount not exceeding each Borrower's respective
Borrowing Amount.

                  (d) EDC as Lender. The amount of Loans that EDC shall be
obligated, subject to the terms and conditions set forth herein, to make to the
Borrowers on the Disbursement Date, notwithstanding anything herein to the
contrary, be limited to an amount equal to EDC's Pro Rata Share (as defined in
the Arranger Participation Agreement) of such proposed Borrowing and any amount
actually received from the Arrangers in respect of their Pro Rata Shares (as
defined in the Arranger Participation Agreement) of such proposed Borrowing.

                  SECTION 2.03. Requests for Borrowings; Interest Elections.

                  (a) Requests for Borrowings. The making of the initial
Borrowing may be requested by a Borrower by means of delivery to the
Administrative Agent of a Borrowing Request by telephone not later than 3:00
p.m., New York time on the Effective Date or the next succeeding Business Day,
two Business Days before the date of the Eurodollar Borrowing proposed therein.
Promptly following receipt of a Borrowing Request in accordance with this
Section, the Administrative Agent shall advise each Lender of the details
thereof and of the amount of such Lender's Loan to be made as part of the
requested Borrowing.

                  The telephonic Borrowing Request delivered pursuant to this
Section 2.03(a) shall be irrevocable and shall be confirmed promptly, and in no
event later than 3:00 p.m., New York time the day of delivery of the telephonic
Borrowing Request, by hand delivery or fax to the Administrative Agent of a
written Borrowing Request, in substantially the form of Exhibit D hereto, signed
by the President or a Financial Officer of each Borrower and to the extent the
proceeds of the Loans to be made as part of the requested Borrowing will be used
to finance purchases from the Supplier permitted under Section 6.08, attaching
invoices from the Supplier for payments due, which are required to be in
compliance with Section 6.08. Each such telephonic and written Borrowing Request
shall specify, in compliance with Section 2.02, (i) the aggregate amount of the
proposed Borrowing and (ii) the date of such Borrowing, which shall be a
Business Day; and shall confirm compliance with the conditions set forth in
Section 5.01(c).

                  (b) Interest Elections.

                  (i) Elections by the Borrowers for Borrowings. For any
         Interest Period that does not end on the Maturity Date, the Borrowers
         shall jointly elect a successor Interest Period pursuant to this
         Section 2.03(b). If the Borrowers do not jointly elect a successor
         Interest Period pursuant to the immediately preceding sentence, the
         Borrowers shall be deemed to have elected an Interest Period of a
         duration equal to the duration of the immediately preceding Interest
         Period. In all cases, the Interest Period election by the Borrowers
         shall be effective hereunder only after having been duly authorized by
         the Central Bank and after the Administrative Agent shall have received
         evidence of such authorization.

<PAGE>   18
                  (ii) Notice of Elections. To make an election pursuant to this
         Section, the Borrowers shall jointly notify the Administrative Agent of
         such election by telephone not later than 3:00 p.m., New York time,
         three Business Days before the first day of the proposed Interest
         Period. Each such telephonic Interest Election Request shall be a
         period contemplated by the definition of the term "Interest Period",
         shall be irrevocable and shall be confirmed promptly by hand delivery
         or telecopy to the Administrative Agent of a written Interest Election
         Request, in substantially the form of Exhibit E hereto and signed by
         the President or a Financial Officer of such Borrower.

                  (iii) Information in Interest Election Requests. Each
         telephonic and written Interest Election Request shall specify the
         following information in compliance with Section 2.02:

                           (A) the effective date of the election made pursuant
                  to such Interest Election Request, which shall be a Business
                  Day; and

                           (B) the Interest Period to be applicable thereto
                  after giving effect to such election, which shall be a period
                  contemplated by the definition of the term "Interest Period".

         If any such Interest Election Request does not specify an Interest
         Period, then the Borrowers shall be deemed to have elected an Interest
         Period of a duration equal to the duration of the immediately preceding
         Interest Period.

                  (iv) Notice by the Administrative Agent to Lenders. Promptly
         following receipt of an Interest Election Request, the Administrative
         Agent shall advise each Lender of the details thereof and of such
         Lender's portion of each resulting Borrowing.

                  SECTION 2.04. Funding of Borrowings.

                  (a) Funding by Lenders. Each Lender shall make each Loan to be
made by it hereunder on the Disbursement Date by wire transfer of immediately
available funds by 10:00 a.m. New York time, to the account of the
Administrative Agent most recently designated by it for such purpose by notice
to the Lenders. The Administrative Agent will promptly credit the amounts so
received, net of all costs, fees (including documentation fees) and
out-of-pocket expenses (including, without limitation, reasonable legal fees and
expenses) of the Lender, Arrangers, and the Administrative Agent with respect to
the negotiation and drafting of the credit documentation and other compensation
payable pursuant to the terms hereof on or prior to the Disbursement Date to the
Lender, Arrangers, and Administrative Agent in like funds, to such account
designated by the relevant Borrower to the Administrative Agent for the purpose
of receiving such funds but in any event no later than 11:00 a.m. New York time.

                  (b) Presumption by the Administrative Agent. Unless the
Administrative Agent shall have received notice from a Lender prior to the
proposed date of any Borrowing that such Lender will not make available to the
Administrative Agent such Lender's share of such Borrowing, the Administrative
Agent may assume that such Lender has made such share available on such date in
accordance with paragraph (a) of this Section and may, in reliance upon such
assumption, make available to the Borrowers a corresponding amount. In such
event, if a Lender has not in fact made its share of the applicable Borrowing
available to the Administrative Agent, then the applicable Lender and the
Borrowers severally agree to pay to the Administrative Agent forthwith on demand
such corresponding amount with interest thereon, for each day from and including
the date such amount is made available to the Borrowers to but excluding the
date of payment to the Administrative Agent, at (i) the interest rate
representing the Administrative Agent's cost to make such amount available to
the Borrowers, as certified by the Administrative Agent (with respect to such
applicable Lender) or (ii) the interest rate then applicable pursuant to Section
2.09(a) (with respect to the Borrowers). If such Lender pays such amount to the
Administrative Agent, then such amount shall constitute such Lender's Loan
included in such Borrowing.

<PAGE>   19
                  SECTION 2.05. Termination and Reduction of the Commitments.

                  (a) Scheduled Termination. Unless previously terminated, the
Commitments shall terminate at 5:00 p.m., New York time, on the Disbursement
Date. The termination of the Commitments shall be permanent.

                  SECTION 2.06. Repayment of Loans; Evidence of Debt.

                  (a) Repayment. Each Borrower hereby unconditionally promises
to pay to the Administrative Agent on behalf and for the account of the Lenders
such Borrower's Principal Repayment Amount on each Principal Payment Date. To
the extent not previously paid, all Loans shall be due and payable on the
Maturity Date.

                  (b) Manner of Payment. Prior to any repayment or prepayment of
any Borrowings hereunder, each Borrower shall select the Borrowing or Borrowings
to be paid and shall notify the Administrative Agent by telephone (confirmed by
fax) of such selection not later than 12:00 p.m., New York time, three Business
Days before the scheduled date of such repayment. If any Borrower fails to make
a timely selection of the Borrowing or Borrowings to be repaid or prepaid, such
payment shall be applied to Borrowings in the order of the remaining duration of
their respective Interest Periods (the Borrowing with the shortest remaining
Interest Period to be repaid first). Each payment of a Borrowing shall be
applied ratably to the Loans included in such Borrowing.

                  (c) Maintenance of Loan Accounts by Lenders. Each Lender shall
maintain in accordance with its usual practice an account or accounts evidencing
the indebtedness of the Borrowers to such Lender resulting from each Loan made
by such Lender, including the amounts of principal and interest payable and paid
to such Lender from time to time hereunder.

                  (d) Maintenance of Loan Accounts by the Administrative Agent.
The Administrative Agent shall maintain accounts in which it shall record (i)
the amount of each Loan made hereunder and the Interest Period applicable
thereto, (ii) the amount of any principal or interest due and payable or to
become due and payable from the Borrowers to each Lender hereunder and (iii) the
amount of any sum received by the Administrative Agent hereunder for the account
of the Lenders and each Lender's share thereof.

                  (e) Effect of Entries. The entries made in the accounts
maintained pursuant to paragraph (c) or (d) of this Section shall be, absent
manifest error, prima facie evidence of the existence and amounts of the
obligations recorded therein; provided that the failure of any Lender or the
Administrative Agent to maintain such accounts or any error therein shall not in
any manner affect the obligation of the Borrowers to repay the Loans in
accordance with the terms of this Agreement.

                  (f) Promissory Notes. Each Loan shall be evidenced by a
promissory note. The Borrowers shall prepare, execute and deliver to each Lender
a promissory note (substantially in the form of Exhibit C) payable to the order
of such Lender (or, if requested by such Lender, to such Lender and its
registered permitted assigns). The Loans and interest thereon shall at all times
(including after assignment pursuant to Section 10.04) be represented by one or
more promissory notes in such form payable to the order of the payee named
therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

                  SECTION 2.07. Prepayment of Loans.

                  (a) Optional Prepayments. Subject to approval by the Central
Bank, if applicable, the Borrowers shall have the right (i) at any time and from
time to time to prepay any Borrowing in whole or (ii) at any time after the
second anniversary of the Effective Date to prepay any Borrowing in part,
subject to the requirements of this Section. If any such prepayment shall occur
prior to the second anniversary of the Disbursement Date, then such Borrower
shall, concurrently with such prepayment, pay Insurance Breakage, in addition to
any costs otherwise payable pursuant to Section 2.12.

                                      E-62
<PAGE>   20
                  (b) Notices, Etc. The Borrowers shall notify the
Administrative Agent by telephone (confirmed by fax) of any proposed prepayment
hereunder, not later than 12:00 p.m., New York time, three Business Days before
the date of prepayment. Each such notice shall be irrevocable and shall specify
the prepayment date, the principal amount of each Borrowing or portion thereof
to be prepaid and the payment or payments against which such prepayment shall be
applied. Promptly following receipt of any such notice relating to a Borrowing,
the Administrative Agent shall advise the relevant Lenders of the contents
thereof. Each partial prepayment of any Loan shall be in an amount no less than
$1,000,000, or any lesser amount as necessary to prepay in full the remaining
outstanding principal amount of such Loan. Each prepayment of a Borrowing shall
be applied ratably to the Loans included in the prepaid Borrowing. Prepayments
shall be accompanied by accrued interest to the extent required by Section 2.09
and shall be made in the manner specified in Section 2.06(c). Amounts prepaid
may not be re-borrowed.

                  SECTION 2.08. Fees.

                  (a) Fee Letter. All fees payable under the letter agreement
dated as of the date hereof among the Borrowers, the Lenders and the
Administrative Agent shall be paid on the due dates set forth therein in
immediately available funds to the Administrative Agent for distribution to the
Person entitled thereto.

                  (b) Payment of Fees. All fees payable hereunder shall be paid
on the dates due, in immediately available funds, to the Administrative Agent
for distribution to the Person entitled thereto. Fees paid under the Loan
Documents shall not be refundable under any circumstances.

                  SECTION 2.09. Interest.

                  (a) Loans. Each Eurodollar Loan shall bear interest at a rate
per annum equal to the Adjusted LIBO Rate for the Interest Period in effect for
the Borrowing of which such Loan is a part plus the Applicable Margin. Each ABR
Loan shall bear interest at a rate per annum equal to the Alternate Base Rate
plus the Applicable Margin.

                  (b) Default Interest. Notwithstanding the foregoing, if any
Default set forth in clause (a) of Article VIII shall have occurred and be
continuing, (i) if such overdue amount is principal of or interest on any
Eurodollar Loan or any overdue amount hereunder other than principal of or
interest on any Loan, such overdue amount shall bear interest, after as well as
before judgment, for any Default Interest Period, at a rate per annum equal to
the Adjusted LIBO Rate for such Default Interest Period plus the Applicable
Margin plus 1% and (ii) if such overdue amount is principal of or interest on
any ABR Loan, such overdue amount shall bear interest, after as well as before
judgment, at a rate per annum equal to the Alternate Base Rate plus the
Applicable Margin plus 1%, in each case, from the applicable date of such
Default until such overdue amount is paid in full.

                  (c) Payment of Interest. Accrued interest on each Loan shall
be payable in arrears on each Interest Payment Date for such Loan and, for any
Loan with a six month Interest Period, on each Quarterly Date for such Loan;
provided that (i) interest accrued pursuant to paragraph (b) of this Section
shall be payable on demand and (ii) in the event of any repayment or prepayment
of any Loan, accrued interest on the principal amount repaid or prepaid shall be
payable on the date of such repayment or prepayment.

                  (d) Computation. All interest hereunder shall be computed on
the basis of a year of 360 days, except that interest computed by reference to
the Alternate Base Rate at times when the Alternate Base Rate is based on the
Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in
a leap year), and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day). The applicable Alternate
Base Rate or Adjusted LIBO Rate shall be determined by the Administrative Agent,
and such determination shall be conclusive absent manifest error.

                  SECTION 2.10. Alternate Rate of Interest.

                  (a) If prior to the commencement of any Interest Period:

                                      E-63
<PAGE>   21
                  (i) the Administrative Agent determines (which determination
         shall be conclusive absent manifest error) that adequate and reasonable
         means do not exist for ascertaining the Adjusted LIBO Rate for such
         Interest Period;

                  (ii) the Administrative Agent is advised by the Required
         Lenders that the Adjusted LIBO Rate for such Interest Period will not
         adequately and fairly reflect the cost to such Lenders of making or
         maintaining their Loans included in such Borrowing for such Interest
         Period; or

                  (iii) it shall be illegal for the Lenders to make any Loan
         that bears interest based upon the Adjusted LIBO Rate;

then the Administrative Agent shall give notice thereof to the Borrowers and the
Lenders by telephone or fax as promptly as practicable thereafter and, until the
Administrative Agent notifies the Borrowers and the Lenders that the
circumstances giving rise to such notice no longer exist, Loans made pursuant to
any Borrowing Request delivered to the Administrative Agent during such period
shall be made as an ABR Borrowing.

                  (b) Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful as a result of a Change in Law
for any Lender to honor its obligation to maintain Eurodollar Loans to any
Borrower hereunder, then such Lender shall promptly notify the Administrative
Agent thereof, and the Administrative Agent shall give prompt notice thereof to
such Borrower. At such time that such Lender notifies the Administrative Agent,
such Lender's obligation to make Eurodollar Loans shall be suspended until such
time as the Lender may again make and maintain Eurodollar Loans and, at the
Borrower's option, either (i) such Borrower shall prepay all such Eurodollar
Loans made by such Lender then outstanding hereunder together with accrued
interest thereon or (ii) as of the date of such suspension, such Loans shall
bear interest at the Adjusted Base Rate until such time as such Lender may again
make and maintain Eurodollar Loans.

                  SECTION 2.11. Increased Costs.

                  (a) Increased Costs Generally. If any Change in Law shall:

                  (i) impose, modify or deem applicable any reserve, special
         deposit or similar requirement against assets of, deposits with or for
         the account of, or credit extended by, any Lender (except any such
         reserve requirement reflected in the Adjusted LIBO Rate); or

                  (ii) impose on any Lender or the London interbank market any
         other condition affecting this Agreement or Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Loan to any Borrower (or of maintaining its
obligation to make any such Loan) or to reduce the amount of any sum received or
receivable by such Lender hereunder (whether of principal, interest or
otherwise) excluding for purposes of this Section 2.11(a) any such increase or
reduction resulting from Indemnified Taxes or Other Taxes (as to which Section
2.13 shall govern), then such Borrower will pay such additional amount or
amounts as will compensate such Lender for such additional costs incurred or
reduction suffered in accordance with Section 2.14(a).

                  (b) Capital Requirements. If any Lender determines that any
Change in Law regarding capital requirements has the effect of reducing the rate
of return on such Lender's capital or on the capital of such Lender's holding
company, if any, as a consequence of this Agreement or the Loans made by such
Lender to any Borrower to a level below that which such Lender or such Lender's
holding company could have achieved but for such Change in Law (taking into
consideration such Lender's policies and the policies of such Lender's holding
company with respect to capital adequacy), then from time to time such Borrower
will pay such additional amount or amounts as will compensate such Lender or
such Lender's holding company for any such reduction suffered in accordance with
Section 2.14(a).

                  (c) Certificates from Lenders. If any Lender becomes entitled
to claim any additional amounts pursuant to this Section, it shall promptly, but
in any event within 45 days after such Lender obtains actual knowledge thereof,
notify the relevant Borrower or Borrowers (with a copy to the Administrative
Agent) in reasonable detail of the reason why it has become so entitled. A
certificate of a Lender setting forth in reasonable detail the calculation and
the amount or amounts necessary to compensate such Lender or its holding
company, as the case may be, as specified in paragraph (a) or (b) of this
Section and the basis thereof shall be delivered to the relevant Borrower or
Borrowers and shall be conclusive absent manifest error, provided that such
determination and calculation of such Lender are made on a reasonable basis. The
relevant Borrower or Borrowers shall pay the amount shown as due on any such
certificate in accordance with Section 2.14(a) within 10 days after receipt
thereof. Notwithstanding anything to the contrary herein, if any Lender fails to
give notice in accordance with this paragraph (c) within 45 days after it
obtains actual knowledge of such an event, such Lender shall, with respect to
compensation payable pursuant to this Section in respect of any costs resulting
from such event, only be entitled to payment under this Section for costs
incurred from and after the date 90 days prior to the date that such Lender does
give such notice.

                  SECTION 2.12. Break Funding Payments. In the event of (i) the
payment by any Borrower of any principal of any Eurodollar Loan other than on an
Interest Payment Date applicable thereto (including as a result of an Event of
Default), (ii) the failure to borrow, continue or prepay any Eurodollar Loan by
any Borrower on the date specified in any notice delivered pursuant hereto, or
(iii) the assignment or participation of any Eurodollar Loan other than on the
last day of the Interest Period applicable thereto as a result of a request by
any Borrower pursuant to Section 2.15 or Section 10.04(g), then, in any such
event, such Borrower shall compensate each Lender for the loss, cost and expense
attributable to such event (but, in any event, excluding any loss of profits and
the Applicable Margin applicable to such Eurodollar Loan). The loss to any
Lender attributable to any such event shall be deemed to be an amount determined
by such Lender to be equal to the excess, if any, of (A) the amount of interest
that such Lender would pay for a deposit equal to the principal amount of the
applicable Eurodollar Loan so prepaid, not borrowed continued or prepaid or
assigned, as applicable, for the period from the date of such payment, failure
or assignment to the last day of the then current Interest Period for such
Eurodollar Loan (or, in the case of a failure to borrow or continue, the
duration of the Interest Period that would have resulted from such borrowing or
continuation) if the interest rate payable on such deposit were equal to the
Adjusted LIBO Rate for such Interest Period, over (B) the amount of interest
that such Lender would earn on such principal amount for such period if such
Lender were to invest such principal amount for such period at the interest rate
that would be bid by such Lender (or an Affiliate of such Lender) for dollar
deposits from other banks in the eurodollar market at the commencement of such
period. A certificate of any Lender setting forth in reasonable detail the
calculation and any amount or amounts that such Lender is entitled to receive
pursuant to this Section shall be delivered to such Borrower and shall be
conclusive absent manifest error. Such Borrower shall pay the amount shown as
due on any such certificate in accordance with Section 2.14(a) within 10 days
after receipt thereof. Notwithstanding anything in this paragraph to the
contrary, the substitution of a Default Interest Period for an Interest Period
with respect to any overdue amount pursuant to Section 2.09(b) shall not impose
any liability on the Borrowers pursuant to this paragraph.

                  SECTION 2.13. Taxes.

                  (a) Payments Free of Taxes. Any and all payments by or on
account of any obligation of the Guarantors hereunder or under any other Loan
Document shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that if any Guarantor shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 2.13(a)) the Administrative Agent or Lender (as the case may
be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) such Guarantor shall make such deductions and (iii)
such Guarantor shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

                  (b) Payment of Other Taxes by the Guarantor. In addition, each
Guarantor shall pay any Other Taxes to the relevant Governmental Authority in
accordance with applicable law.

                                      E-65
<PAGE>   23
                  (c) Indemnification by the Guarantor. Each Guarantor shall
indemnify the Administrative Agent and each Lender, within 10 days after written
demand therefor, for the full amount of any Indemnified Taxes or Other Taxes
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section 2.13(c)) paid with respect to
any and all payments by or on account of any obligation of such Guarantor
hereunder or under any other Loan Document by the Administrative Agent or such
Lender, as the case may be, and any penalties, interest and reasonable expenses
paid by the Administrative Agent or such Lender, as the case may be, arising
therefrom or with respect thereto (other than penalties, interest and expenses
that arise solely as a result of the gross negligence or willful misconduct of
the Administrative Agent or such Lender), whether or not such Indemnified Taxes
or Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. To the extent practicable, each of the Administrative
Agent and each Lender agrees to use reasonable efforts to provide the Guarantors
with notice of the imposition of any Indemnified Taxes or Other Taxes upon such
Person prior to the payment of such Indemnified Taxes or Other Taxes, provided
that the delivery of such notice will not subject such Person to any
unreimbursed cost or expense or other disadvantage. A certificate specifying the
amount of such payment and a reasonable explanation of the calculation thereof
delivered pursuant to this Section 2.13(c) to the Guarantors by a Lender, or by
the Administrative Agent on its own behalf or on behalf of a Lender, shall be
conclusive absent manifest error.

                  (d) Evidence of Payments. As soon as practicable after any
payment of Indemnified Taxes or Other Taxes by any Guarantor to a Governmental
Authority, such Guarantor shall deliver to the Administrative Agent the original
or a certified copy of a receipt issued by such Governmental Authority
evidencing such payment, if available, and a copy of the return reporting such
payment or other evidence of such payment reasonably satisfactory to the
Administrative Agent.

                  (e) Forms. If the Administrative Agent or any Lender or
Arranger is entitled to an exemption from or reduction of any Indemnified Taxes
or Other Taxes under applicable law with respect to payments under this
Agreement or any other Loan Document, such Person shall deliver to each
applicable Guarantor (with a copy to the Administrative Agent), at the time or
times prescribed by applicable law or reasonably requested by such Guarantor,
such properly completed and executed documentation prescribed by applicable law
as will permit such payments to be made without withholding or at a reduced
rate, provided that the delivery, completion or execution of such documentation
will not subject such Lender to any unreimbursed cost or expense and would not
otherwise be unduly disadvantageous to such Lender, provided further that such
Lender's failure to fulfill its obligations pursuant to this Section 2.13(e)
shall not relieve any Guarantor of any of its obligations under this Agreement.

                  (f) Tax Benefits. If the Administrative Agent or any Lender or
Arranger shall determine, in its sole reasonable discretion, that it has
received a refund of any Indemnified Taxes or Other Taxes paid or indemnified by
any Guarantor pursuant to Section 2.13(a), Section 2.13(b), or Section 2.13(c),
the Administrative Agent or such Lender or Arranger, as the case may be, shall
to the extent that it determines that such refund is attributable to Indemnified
Taxes or Other Taxes paid or indemnified by such Guarantor, so advise such
Guarantor and pay to such Guarantor an amount that the Administrative Agent or
such Lender or Arranger, as the case may be, shall determine is equal to the
lesser of such refund and the amount of Indemnified Taxes or Other Taxes
actually paid or indemnified by such Guarantor in respect of which such refund
was made, provided that such Person determines that any such payment to such
Guarantor shall not prejudice the retention of such refund by such Person.

                  (g) Limitations. Notwithstanding anything to the contrary
contained hereunder or under any other Loan Document, the Guarantors shall only
be required to make payments pursuant to Section 2.13(a)(i) or Section 2.13(c)
to the extent the rate of Indemnified Taxes does not exceed the rate of
withholding tax on interest to Persons who are not located in Tax Haven
Jurisdictions.

                  SECTION 2.14. Payments Generally; Pro Rata Treatment; Sharing
of Set-offs.

                  (a) Payments by the Guarantors. Each Guarantor shall make each
payment required to be made by it hereunder (whether of principal, interest or
fees, or under Section 2.11, 2.12 or 2.13, or otherwise) or under any other Loan
Document (except to the extent otherwise provided therein) prior to 12:00 p.m.,
New York

                                      E-66
<PAGE>   24
time, on the date when due, in immediately available funds, without set-off or
counterclaim. Any amounts received after such time on any date may, in the
discretion of the Administrative Agent, be deemed to have been received on the
next succeeding Business Day for purposes of calculating interest thereon. All
such payments, except as otherwise expressly provided in the relevant Loan
Document, shall be made to the Administrative Agent at its offices in New York,
N.Y. (i) so long as EDC shall be the sole Lender hereunder, to an account in the
name of EDC at BankBoston N.A., as notified by the Administrative Agent to the
Guarantors or (ii) otherwise, pursuant to notice from the Administrative Agent
of an assignment by EDC pursuant to Section 10.04(b) of any Loan or Commitment,
(A) with respect to amounts owing to EDC subsequent to such assignment, to the
account referred to in clause (i) of this sentence and (B) with respect to all
other amounts, to an account as notified by the Administrative Agent to the
Guarantors. To the extent any Guarantor has not received notice from the
Administrative Agent with respect to the division of payments due hereunder
between the accounts listed in clause (ii) in the immediately preceding
sentence, the Guarantors shall use their reasonable efforts to divide any such
payments between such accounts in accordance with the amounts actually owed to
EDC and the other Lenders, respectively. To the extent the Administrative Agent
shall receive any such payments for the account of any other Person, it shall
distribute such payments to the appropriate recipient promptly following receipt
thereof. If any payment hereunder shall be due on a day that is not a Business
Day, the date for payment shall be extended to the next succeeding Business Day
and, in the case of any payment accruing interest, interest thereon shall be
payable for the period of such extension. All payments hereunder or under any
other Loan Document shall be made in dollars.

                  (b) Application of Insufficient Payments. If at any time
insufficient funds are received by and available to the Administrative Agent to
pay fully all amounts of principal, interest and fees then due hereunder, such
funds shall be applied (i) first, to pay interest and fees then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
interest and fees then due to such parties, and (ii) second, to pay principal
then due hereunder, ratably among the parties entitled thereto in accordance
with the amounts of principal then due to such parties.

                  (c) Pro Rata Treatment. Except to the extent otherwise
provided herein: (i) each Borrowing shall be made from the relevant Lenders, and
each termination of the amount of the Commitments under Section 2.05 shall be
applied to the respective Commitments of the relevant Lenders, pro rata
according to the amounts of their respective Commitments; (ii) each payment or
prepayment of principal of the Loans by the Borrowers shall be made for account
of the relevant Lenders pro rata in accordance with the respective unpaid
principal amounts of the Loans held by them; and (iii) each payment of interest
on Loans by the Borrowers shall be made for account of the relevant Lenders pro
rata in accordance with the respective amounts of interest on such Loans then
due and payable to them.

                  (d) Sharing of Payments by Lenders. If any Lender shall, by
exercising any right of set-off or counterclaim or otherwise, obtain payment in
respect of any principal of or interest on any of its Loans resulting in such
Lender receiving payment of a greater proportion of the aggregate amount of its
Loans and accrued interest thereon then due than the proportion received by any
other Lender, then the Lender receiving such greater proportion shall purchase
(for cash at face value) participations in the Loans of other Lenders to the
extent necessary so that the benefit of all such payments shall be shared by the
Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Loans; provided that (i) if any such
participations are purchased and all or any portion of the payment giving rise
thereto is recovered, such participations shall be rescinded and the purchase
price restored to the extent of such recovery, without interest, and (ii) the
provisions of this paragraph shall not be construed to apply to any payment made
by the Borrowers pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans to any assignee or
participant, other than to the Borrowers or any Affiliate of the Borrowers (as
to which the provisions of this paragraph shall apply). Each of the Borrowers
consents to the foregoing and agrees, to the extent it may effectively do so
under applicable law, that any Lender acquiring a participation pursuant to the
foregoing arrangements may exercise against such Borrower rights of set?off and
counterclaim with respect to such participation as fully as if such Lender were
a direct creditor of such Borrower in the amount of such participation.

                                      E-67
<PAGE>   25
                  (e) Presumptions of Payment. Unless the Administrative Agent
shall have received notice from any of the Borrowers prior to the date on which
any payment is due to the Administrative Agent for the account of the Lenders
hereunder that any Borrower will not make such payment, the Administrative Agent
may assume that the Borrowers have made such payment on such date in accordance
herewith and may, in reliance upon such assumption, distribute to the Lenders
the amount due. In such event, if the Borrowers have not in fact made such
payment, then each of the Lenders severally agrees to repay to the
Administrative Agent forthwith on demand the amount so distributed to such
Lender with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the
Administrative Agent, at the Federal Funds Effective Rate.

                  (f) Certain Deductions by the Administrative Agent. If any
Lender shall fail to make any payment required to be made by it pursuant to
Section 2.04(b) or 2.14(e), then the Administrative Agent may, in its discretion
(notwithstanding any contrary provision hereof), apply any amounts thereafter
received by the Administrative Agent for the account of such Lender to satisfy
such Lender's obligations under such Sections until all such unsatisfied
obligations are fully paid.

                  SECTION 2.15. Mitigation; Replacement of Lenders.

                  (a) Designation of a Different Lending Office. If any Lender
requests compensation under Section 2.11, or if any of the Borrowers is required
to pay any additional amount to any Lender or any Governmental Authority for the
account of any Lender pursuant to Section 2.13, or if any Lender is unable to
make or maintain a Eurodollar Loan pursuant to a Change of Law described in
Section 2.10(b), upon such Borrower's request such Lender shall use reasonable
efforts to designate a different lending office for funding or booking its Loans
hereunder or to assign its rights and obligations hereunder to another of its
offices, branches or, with the consent of such Borrower, Affiliates, if, in the
judgment of such Lender, such designation or assignment (i) would eliminate or
reduce amounts payable pursuant to Section 2.11 or 2.13 or obviate the effect of
such Change in Law, as the case may be, in the future and (ii) would not subject
such Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. The Borrowers hereby agree to pay all reasonable
costs and expenses incurred by any Lender in connection with any such
designation or assignment.

                  (b) Replacement of Lenders. If any Lender requests
compensation under Section 2.11, or if any Borrower is required to pay any
additional amount to any Lender or any Governmental Authority for the account of
any Lender pursuant to Section 2.13, or if any Lender is unable to make or
maintain a Eurodollar Loan pursuant to a Change of Law described in Section
2.10(b), or if any Lender defaults in its obligation to fund Loans hereunder,
then such Borrower may, at its sole expense and effort, upon notice to such
Lender and the Administrative Agent, require such Lender to assign and delegate,
without recourse (in accordance with and subject to the restrictions contained
in Section 10.04), all its interests, rights and obligations under this
Agreement to an assignee that shall assume such obligations (which assignee may
be another Lender, if a Lender accepts such assignment); provided that (i) such
Borrower shall have received the prior consent of the Administrative Agent,
which consent shall not unreasonably be withheld, (ii) such Lender shall have
received payment of an amount equal to the outstanding principal of its Loans,
accrued interest thereon, accrued fees and all other amounts payable to it
hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or such Borrower (in the case of all other amounts)
and (iii) in the case of any such assignment resulting from a claim for
compensation under Section 2.11 or payments required to be made pursuant to
Section 2.13, such assignment will result in a reduction in such compensation or
payments. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling such Borrower to require such assignment
and delegation cease to apply.

                                  ARTICLE III

                                    GUARANTEE

                  SECTION 3.01. The Guarantee. The Guarantors hereby jointly and
severally guarantee to each Lender and the Administrative Agent and their
respective successors and assigns the prompt payment in full when

                                      E-68
<PAGE>   26
due (whether at stated maturity, by acceleration or otherwise) of the principal
of and interest on the Loans made by the Lenders to each other Guarantor and all
other amounts from time to time owing to the Lenders or the Administrative Agent
by each other Guarantor under this Agreement or under any of the other Loan
Documents, in each case strictly in accordance with the terms thereof (such
obligations being herein collectively called the "Guaranteed Obligations"). The
Guarantors hereby further jointly and severally agree that if any other
Guarantor shall fail to pay in full when due (whether at stated maturity, by
acceleration or otherwise) any of the Guaranteed Obligations, the Guarantors
will promptly pay the same, without any demand or notice whatsoever, and that in
the case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, by acceleration or otherwise) in accordance with the terms of
such extension or renewal.

                  SECTION 3.02. Obligations Unconditional. The obligations of
the Guarantors under Section 3.01 are absolute and unconditional, joint and
several, irrespective of the value, genuineness, validity, regularity or
enforceability of the obligations of the Borrowers under this Agreement or any
other agreement or instrument referred to herein, or any substitution, release
or exchange of any other guarantee of or security for any of the Guaranteed
Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section that the obligations of the Guarantors
hereunder shall be absolute and unconditional, joint and several, under any and
all circumstances. Without limiting the generality of the foregoing, it is
agreed that the occurrence of any one or more of the following shall not alter
or impair the liability of the Guarantors hereunder, which shall remain absolute
and unconditional as described above:

                  (i) at any time or from time to time, without notice to the
         Guarantors, the time for any performance of or compliance with any of
         the Guaranteed Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (ii) any of the acts mentioned in any of the provisions of
         this Agreement or any other agreement or instrument referred to herein
         shall be done or omitted;

                  (iii) the maturity of any of the Guaranteed Obligations shall
         be accelerated, or any of the Guaranteed Obligations shall be modified,
         supplemented or amended in any respect, or any right under this
         Agreement or any other agreement or instrument referred to herein shall
         be waived or any other guarantee of any of the Guaranteed Obligations
         or any security therefor shall be released or exchanged in whole or in
         part or otherwise dealt with; or

                  (iv) any lien or security interest granted to, or in favor of,
         the Administrative Agent or any Lender or Lenders as security for any
         of the Guaranteed Obligations shall fail to be perfected.

The Guarantors hereby expressly waive diligence, presentment, demand of payment,
protest and all notices whatsoever, and any requirement that the Administrative
Agent or any Lender exhaust any right, power or remedy or proceed against the
Borrowers under this Agreement or any other agreement or instrument referred to
herein, or against any other Person under any other guarantee of, or security
for, any of the Guaranteed Obligations.

                  SECTION 3.03. Reinstatement. The obligations of the Guarantors
under this Article shall be automatically reinstated if and to the extent that
for any reason any payment by or on behalf of the Borrowers in respect of the
Guaranteed Obligations is rescinded or must be otherwise restored by any holder
of any of the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise.

                  SECTION 3.04. Subrogation. The Guarantors hereby jointly and
severally agree that until the payment and satisfaction in full of all
Guaranteed Obligations and the expiration and termination of the Commitments of
the Lenders under this Agreement they shall not exercise any right or remedy
arising by reason of any performance by them of their guarantee in Section 3.01,
whether by subrogation or otherwise, against the Borrowers or any other
guarantor of any of the Guaranteed Obligations or any security for any of the
Guaranteed Obligations.

                                      E-69
<PAGE>   27
                  SECTION 3.05. Remedies. The Guarantors jointly and severally
agree that, as between the Guarantors and the Lenders, the obligations of the
Borrowers under this Agreement may be declared to be forthwith due and payable
as provided in Article VIII (and shall be deemed to have become automatically
due and payable in the circumstances provided in Article VIII) for purposes of
Section 3.01 notwithstanding any stay, injunction or other prohibition
preventing such declaration (or such obligations from becoming automatically due
and payable) as against the Borrowers and that, in the event of such declaration
(or such obligations being deemed to have become automatically due and payable),
such obligations (whether or not due and payable by the Borrowers) shall
forthwith become due and payable by the Guarantors for purposes of Section 3.01.

                  SECTION 3.06. Instrument for the Payment of Money. Each
Guarantor hereby acknowledges that the guarantee in this Article constitutes an
instrument for the payment of money, and consents and agrees that any Lender or
the Administrative Agent, at its sole option, in the event of a dispute by such
Guarantor in the payment of any moneys due hereunder, shall have the right to
bring motion action under New York CPLR Section 3213.

                  SECTION 3.07. Continuing Guarantee. The guarantee in this
Article is a continuing guarantee, and shall apply to all Guaranteed Obligations
whenever arising.

                  SECTION 3.08. Rights of Contribution. The Guarantors hereby
agree, as between themselves, that if any Guarantor shall become an Excess
Funding Guarantor (as defined below) by reason of the payment by such Guarantor
of any Guaranteed Obligations, each other Guarantor shall, on demand of such
Excess Funding Guarantor (but subject to the next sentence), pay to such Excess
Funding Guarantor an amount equal to such Guarantor's Pro Rata Share (as defined
below and determined, for this purpose, without reference to the properties,
debts and liabilities of such Excess Funding Guarantor) of the Excess Payment
(as defined below) in respect of such Guaranteed Obligations. The payment
obligation of a Guarantor to any Excess Funding Guarantor under this Section
shall be subordinate and subject in right of payment to the prior payment in
full of the obligations of such Guarantor under the other provisions of this
Article and such Excess Funding Guarantor shall not exercise any right or remedy
with respect to such excess until payment and satisfaction in full of all of
such obligations.

                  For purposes of this Section, (i) "Excess Funding Guarantor"
means, in respect of any Guaranteed Obligations, a Guarantor that has paid an
amount in excess of its Pro Rata Share of such Guaranteed Obligations, (ii)
"Excess Payment" means, in respect of any Guaranteed Obligations, the amount
paid by an Excess Funding Guarantor in excess of its Pro Rata Share of such
Guaranteed Obligations and (iii) "Pro Rata Share" means, for any Guarantor, the
ratio (expressed as a percentage) of (x) the amount by which the aggregate
present fair saleable value of all properties of such Guarantor (excluding any
shares of stock of any other Guarantor) exceeds the amount of all the debts and
liabilities of such Guarantor (including contingent, subordinated, unmatured and
unliquidated liabilities, but excluding the obligations of such Guarantor
hereunder and any obligations of any other Guarantor that have been Guaranteed
by such Guarantor) to (y) the amount by which the aggregate fair saleable value
of all properties of all of the Guarantors exceeds the amount of all the debts
and liabilities (including contingent, subordinated, unmatured and unliquidated
liabilities, but excluding the obligations of the Borrowers and the Guarantors
hereunder and under the other Loan Documents) of all of the Guarantors,
determined (A) with respect to any Guarantor that is a party hereto on the
Disbursement Date, as of the Disbursement Date, and (B) with respect to any
other Guarantor, as of the date such Guarantor becomes a Guarantor hereunder.

                  SECTION 3.09. General Limitation on Guarantee Obligations. In
any action or proceeding involving any state corporate law, or any state or
Federal bankruptcy, insolvency, reorganization or other law affecting the rights
of creditors generally, if the obligations of any Guarantor under Section 3.01
would otherwise, taking into account the provisions of Section 3.08, be held or
determined to be void, invalid or unenforceable, or subordinated to the claims
of any other creditors, on account of the amount of its liability under Section
3.01, then, notwithstanding any other provision hereof to the contrary, the
amount of such liability shall, without any further action by such Guarantor,
any Lender, the Administrative Agent or any other Person, be automatically
limited and reduced to the highest amount that is valid and enforceable and not
subordinated to the claims of other creditors as determined in such action or

Transactions and the exercise by the Administrative Agent of any of its rights
under the Loan Documents (i) do not require such Guarantor to obtain or make any

Authority (including ANATEL, the Ministry of Communications and the Central
Bank), except (a) prior approvals issued by the Central Bank, which authorize
the closing of exchange in connection with each disbursement of the proceeds of

Lien on any asset of such Guarantor.

                  SECTION 4.04. All Approvals in Place. All approvals,

not capable as a matter of applicable law or prevailing practice of the relevant
Brazilian Governmental Authority or third party of being

                                      E-71

financial position and results of operations and cash flows of the Parent on a
consolidated basis as of such date and for such period in accordance with GAAP.

                  (b) No Material Adverse Change; No Undisclosed Liabilities.

or otherwise permitted by contractual arrangement to use, all trademarks,
tradenames, copyrights, patents and other intellectual property material to and
used in its current business, and the use thereof by such Guarantor does not

Brazilian Governmental Authority now pending against or, to the knowledge of
such Guarantor, threatened against or affecting such Guarantor other than

to have a Material Adverse Effect. At all other times, except as otherwise
disclosed to the Administrative Agent, there are no actions, suits or
proceedings by or before any arbitrator or Brazilian Government Authority now

Guarantor is in compliance in all material respects with all laws, regulations
and orders of any Brazilian Governmental Authority applicable to it or its

of the reports, financial statements, certificates or other written information
furnished by or on behalf of such Guarantor to the Lender in connection with the
negotiation of this Agreement and the other Loan Documents or delivered
hereunder or thereunder (as modified or supplemented by other written
information so furnished) contains any material misstatement of fact or omits to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading; and, as of the
Disbursement Date, no event or circumstance has occurred since the time any such
statement or information was made or furnished that, if it had occurred prior to
the time that the relevant statement or information was made or furnished, would
have made such statement or information misleading in any material respect if
not disclosed; provided that, with respect to projected financial information,
such Guarantor represents only that such information was prepared in good faith
based upon assumptions believed to be reasonable at the time.

below, each of the Loan Documents is in proper legal form under the law of
Brazil for the enforcement thereof against such Guarantor under such law and
would constitute legal, valid and binding obligations of such Guarantor under
such law, enforceable in accordance with their respective terms, except as such
enforceability may be limited by bankruptcy, insolvency, reorganization,
concordata, moratorium or similar laws of general applicability affecting the
enforcement of creditors' rights; provided however that, in order to ensure the
admission of the Loan Documents before the public agencies and courts in Brazil
(a) the signatures of the parties thereto signing outside Brazil shall be
notarized by a notary public licensed as such under the laws of the place of
signing and the signature of such notary public should be authenticated by a
consular official of Brazil and the Loan Documents must be translated into the

Brazil, or any political subdivision thereof or therein in each case for the
validity and enforceability thereof.

                  SECTION 4.14. Ranking. This Agreement and the other Loan
Documents and the obligations evidenced hereby and thereby are and will at all

its obligations, including Tax liabilities as they become due, that, if not
paid, are reasonably likely to result in a Material Adverse Effect before the
same shall become delinquent or in default, except where (i) the validity or
amount thereof is being contested in good faith by appropriate proceedings, (ii)
such Guarantor has set aside on its books adequate reserves with respect thereto
in accordance with GAAP and (iii) the failure to make payment pending such
contest could not reasonably be expected to result in a Material Adverse Effect.

                  SECTION 6.05. Maintenance of Properties; Insurance. Each
Guarantor will (i) keep and maintain all property material to the conduct of its
business in good working order and condition, ordinary wear and tear excepted,

Administrative Agent only, to discuss its affairs, finances and condition with
its officers and independent accountants, all at such reasonable times and as
often as reasonably requested, provided that the cost and expenses of such
representatives shall be for the account of the Administrative Agent or such
Lender.

                  SECTION 6.07. Compliance with Laws. Each Guarantor will comply
with all laws, rules, regulations and orders of any Governmental Authority
applicable to it or its property, except where the failure to do so,
individually or in the aggregate, is not reasonably likely to result in a
Material Adverse Effect.

                  SECTION 6.08. Use of Proceeds. The proceeds of the Loans will
be used solely (i) to finance payment obligations (A) paid or payable to the
Supplier pursuant to the Supply Contract, (B) with respect to the design,
manufacture and supply of the Equipment, (C) with respect to services pertaining
to the installation and testing of the Equipment, and (D) with respect to
training of the personnel provided by any Guarantor regarding the Equipment, and
(ii) to pay fees due pursuant to Section 2.08 and other transaction costs and
expenses. No part of the proceeds of any Loan will be used to finance the
purchase of equipment or services provided by a competitor of the Supplier. In
the event that invoices from the Supplier are attached to the Borrowing Request
pursuant to Section 2.03(a), the proceeds from the Loans made pursuant to such
Borrowing Request will be used solely to pay such invoices to the extent set
forth in the Borrowing Request.

                  SECTION 6.09. Taxes. Each Guarantor shall, and shall cause
each of its Subsidiaries to, file all material tax returns that are required to
be filed by such Person and pay and discharge all Taxes on such Person's income,
profits or property in a timely manner but in any event prior to the date on
which penalties attach thereto; provided that such Person shall not be required
to discharge any Tax that is being contested in good faith and by appropriate
proceedings diligently pursued and for which adequate reserves are being
maintained or any Tax, the disputed amount of which is immaterial and as to
which no enforcement action has been commenced.

                  SECTION 6.10. Governmental Approvals. Each Guarantor agrees
that it will at its own expense (i) maintain in full force and effect, to the
extent such have already been obtained and continue to be necessary for the
conduct of the operations of such Guarantor and (ii) promptly obtain from time
to time, to the extent such have not already been obtained, all such
governmental licenses, authorizations, consents, permits and approvals as may be
required for such Guarantor to comply with its obligations, and preserve its
rights under, each of the Loan Documents, except in each case those governmental
licenses, authorizations, consents, permits and approvals (a) the absence of
which are not reasonably likely to have a Material Adverse Effect or (b) that
are not capable of being obtained at the present time or that are not capable as
a matter of applicable law or prevailing practice of the relevant Brazilian
Governmental Authority or third party of being obtained at the present time (but
as to which, in any such case such Guarantor knows of no reason the same will
not be obtained in due course).

                  SECTION 6.11. Conduct of Business. Each Guarantor shall at all
times conduct its business in accordance with prudent business and financial
practices.

                  SECTION 6.12. Supply Contract; Organizational Documents. Each
Guarantor shall (i) not amend, supplement, modify or waive any provision of its
charter or bylaws, the Concession, or the Supply Contract if such amendment,
supplement, modification or waiver is reasonably likely to have a Material
Adverse Effect; and (ii) enforce against the relevant counterparty thereto each
material covenant or obligation under the Supply Contract in accordance with its
terms, except to the extent where failure to so enforce is not reasonably likely
to have a Material Adverse Effect.

                  SECTION 6.13. Financial Covenants.

                  (a) Total Leverage Ratio. The Borrowers (on a Combined Basis)

Combined Basis) will not, at any date, permit the aggregate outstanding amount
of Net Foreign Currency Indebtedness to exceed 200% of Annualized EBITDA as of
the end of the most recently completed fiscal quarter.

                  (c) EBITDA to Debt Service Ratio. The Borrowers (on a Combined
Basis) will not permit, as of the end of the most recently completed fiscal
quarter, Annualized EBITDA for such fiscal quarter to be an

                                      E-78

amount less than (i) in the case of each fiscal quarter during the period
beginning as of the Disbursement Date through December 31, 2001, 225% of Debt
Service for the then most recently completed four fiscal quarters; or (ii) in
the case of each fiscal quarter during the period beginning January 1, 2002
through the Maturity Date, 150% of Debt Service for the then most recently

                  SECTION 6.14. Registration of Prior Approval. Within 30 days
from the Disbursement Date, each Borrower shall register the applicable Prior
Approval with the Central Bank in order to obtain the Certificate of
Registration with respect to such disbursement and shall provide the
Administrative Agent with satisfactory evidence of such registration.

                  SECTION 6.15. Collateral Account. Upon the failure of the
Borrowers to comply with the provisions of Section 6.13, any Borrower may notify
the Administrative Agent to establish a Collateral Account to hold amounts
intended to cure such failure pursuant to Article VIII(d). All amounts deposited
by any Borrower or on behalf of the Borrowers in the Collateral Account pursuant
to Article VIII(d) shall be invested by the Administrative Agent in Cash
Equivalents as requested by the Borrowers and reasonably acceptable to the
Administrative Agent. Following the creation of a Collateral Account pursuant to
this Section with respect to any failure of the Borrowers to comply with the
provisions of Section 6.13, at such time that the Borrowers shall certify their
then-current compliance with the provisions of Section 6.13, the Administrative
Agent shall promptly remit all amounts on deposit in the Collateral Account
(including the proceeds from any investments in Cash Equivalents) to the
Borrowers.

         but unpaid);

                  (iii) other unsecured Indebtedness; provided that any such

         to the lender of such Indebtedness and (B) have economic terms no more
         favorable to the lender of such Indebtedness than arm's-length terms
         available to such Borrower on the date of incurrence of such

<PAGE>   37
         exceed 2.0% of the Total Assets of the Borrowers (on a Combined Basis)

actual credit rating.

                  (b) Lines of Business. Such Borrower will not engage in any
business other than the provision of telecommunications services expressly

fiscal period net of ICMS Tax. In the event that the amount of Restricted
Payments paid or made during a fiscal period in accordance with this Section are
in an amount less than the amount permitted in the immediately preceding
sentence for such fiscal period, the excess of such permitted amount over such
amount of Restricted Payments so paid or made will be added to the amount
permitted in the immediately preceding sentence for the subsequent fiscal period
and such aggregate sum will be deemed to be the amount permitted for such
subsequent fiscal period. Except to the extent permitted herein and except for

                                EVENTS OF DEFAULT

                  If any of the following events ("Events of Default") shall
occur:

                  (a) any Guarantor shall fail to pay or cause to be paid (i)
any principal when and as the same shall become due and payable under any Loan
Document, whether at the due date thereof or at a date fixed for prepayment
thereof or otherwise, or (ii) any other amount (including interest and fees)
when and as the same shall become due and payable under the Loan Document and
such failure under the preceding clause (ii) continues for 3 Business Days after
the same shall have become due and payable;

                  (b) any representation or warranty made by or on behalf of any
Guarantor in or in connection with this Agreement or any other Loan Document or
any amendment or modification hereof or thereof, or in any written report,
certificate, financial statement or other document furnished pursuant to or in
connection with this Agreement or any other Loan Document or any amendment or
modification hereof or thereof, shall prove to have been incorrect in any
material respect when made or deemed made;

                  (c) any Guarantor shall fail to observe or perform any
covenant, condition or agreement contained in Section 6.02(i), (ii) or (iii),

<PAGE>   40
                  (d) the Borrowers shall fail to observe or perform any
covenant, condition or agreement contained in Section 6.13 and such failure
shall continue unremedied for a period of 30 or more days after the earlier of
the actual knowledge of such failure by any Borrower or 45 days after the end of
the fiscal quarter in which such failure occurred, provided that, with respect
to any covenant, condition or agreement contained in (i) Section 6.13(a) or (b),
if (I) within such 30 day period the Borrowers shall have caused to be made a
deposit in the Collateral Account established in connection with such failure of
an amount such that the aggregate outstanding amount of Net Indebtedness or Net
Foreign Currency Indebtedness, as the case may be, as at the end of the most
recently completed fiscal quarter shall not exceed 250% or 200%, as applicable,
of the sum of (w) the amount on deposit in such Collateral Account (after
conversion into dollars by dividing such reais amount on deposit by the PTAX 800
Rate) and (x) Annualized EBITDA for the most recently completed four fiscal
quarters, and (II) within 30 days after the end of the next fiscal quarter,
either the Borrowers shall have attained compliance with the covenant, condition
or agreement in such Section (notwithstanding the maintenance of any deposits in
the Collateral Account) for such subsequent fiscal quarter or the Borrowers
shall have (A) caused to be prepaid Indebtedness, (B) received irrevocable
capital contributions or Subordinated Indebtedness or (C) caused an assignment
or participation of Assigned Affiliate Indebtedness, in each case in an amount
such that the covenant, condition or agreement contained in such Section for
such subsequent fiscal quarter would have been fulfilled were such prepayment,
contributions, Subordinated Indebtedness, assignment or participation included
in the calculation therefor (ceteris paribus, notwithstanding the maintenance of
any deposits in the Collateral Account), then the Borrowers shall be deemed to
have remedied such failure and (ii) Section 6.13(c), if within 30 days after
such failure the Borrowers shall have caused to be made a deposit in the
Collateral Account established in connection with such failure of an amount, and
at all times thereafter until such time that the Borrowers shall certify their
then-current compliance with Section 6.13(c) (notwithstanding the maintenance of
any deposits in the Collateral Account), as the case may be, shall maintain on
deposit in such account an amount, such that the sum of (y) the amount on
deposit in such Collateral Account (after conversion into dollars by dividing
such reais amount on deposit by the PTAX 800 Rate) and (z) Annualized EBITDA for
the most recently completed four fiscal quarters equals an amount no less than
225%, if on or prior to December 31, 2001, or 150%, if thereafter, of Debt
Service for the most recently completed four fiscal quarters, then the Borrowers
shall be deemed to have remedied such failure.

                  (e) any Guarantor shall fail to observe or perform any
covenant, condition or agreement contained in this Agreement (except those
referred to in the immediately preceding paragraphs (c) and (d)) or any material
covenant, condition or agreement contained in any other Loan Document and such
failure shall continue unremedied for a period of 30 or more days after such
Guarantor has actual notice thereof;

                  (f) any Guarantor shall fail to make (i) any payment (whether
of principal or interest and regardless of amount) in respect of any Material
Indebtedness of such Guarantor; (ii) at any time that EDC shall be a Lender
hereunder, any payment (whether of principal or interest and regardless of
amount) in respect of Indebtedness owing to EDC, provided that any grace period
applicable to such failure under such Material Indebtedness or such Indebtedness
shall have expired;

                  (g) any event or condition occurs that results in any Material
Indebtedness of any Guarantor becoming due prior to its scheduled maturity or
that enables or permits (and any grace period applicable to such event or
condition under such Indebtedness shall have expired) the holder or holders of
any Material Indebtedness of such Guarantor or any trustee or agent on its or
their behalf to cause any Material Indebtedness of such Guarantor to become due,
or to require the prepayment, repurchase, redemption or defeasance thereof,

any Borrower described in clause (h) or (i) of this Article, the Commitments
shall automatically terminate and the principal of the Loans then outstanding,

presentment, demand, protest or other notice of any kind, all of which are
hereby waived by each of the Borrowers.

                                   ARTICLE IX

                            THE ADMINISTRATIVE AGENT

                  SECTION 9.01. Appointment of Administrative Agent. Each of the
Lenders hereby irrevocably appoints the Administrative Agent as its agent
hereunder and under the other Loan Documents and authorizes the Administrative
Agent to take such actions on its behalf and to exercise such powers as are
delegated to the Administrative Agent by the terms hereof or thereof, together
with such actions and powers as are reasonably incidental thereto.

                  SECTION 9.02. Rights as a Lender. In the event the Person
serving as the Administrative Agent hereunder shall become a Lender, such Person
shall have the same rights and powers in its capacity as a Lender as any other
Lender and may exercise the same as though it were not the Administrative Agent,
and such Person and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with any Guarantor or any Affiliate
thereof as if it were not the Administrative Agent hereunder.

                  SECTION 9.03. Duties and Obligations. The Administrative Agent
shall not have any duties or obligations except those expressly set forth herein
and in the other Loan Documents. Without limiting the generality of the
foregoing, (i) the Administrative Agent shall not be subject to any fiduciary or
other implied duties, regardless of whether a Default has occurred and is
continuing, (ii) the Administrative Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated hereby or by the other Loan Documents
that the Administrative Agent is required to exercise in writing by the Required
Lenders, and (iii) except as expressly set forth herein and in the other Loan
Documents, the Administrative Agent shall not have any duty to disclose, and
shall not be liable for the failure to disclose, any information relating to any
Guarantor that is communicated to or obtained by the bank serving as
Administrative Agent or any of its Affiliates in any capacity. The
Administrative Agent shall not be liable for any action taken or not taken by it
with the consent or at the request of the Required Lenders or in the absence of
its own gross negligence or willful misconduct. The Administrative Agent shall
be deemed not to have knowledge of any Default unless and until written notice
thereof is given to the Administrative Agent by any Guarantor or a Lender, and
the Administrative Agent shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in
or in connection with this Agreement or any other Loan Document, (ii) the
contents of any certificate, report or other document delivered hereunder or
thereunder or in connection herewith or therewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth herein or therein, (iv) the validity, enforceability, effectiveness or
genuineness of this Agreement, any other Loan Document or any other agreement,
instrument or document, or (v) the satisfaction of any condition set forth in
Article V or elsewhere herein or therein, other than to confirm receipt of items
expressly required to be delivered to the Administrative Agent.

                  SECTION 9.04. Reliance. The Administrative Agent shall be
entitled to rely upon, and shall not incur any liability for relying upon, any
notice, request, certificate, consent, statement, instrument, document or other
writing believed by it to be genuine and to have been signed or sent by the
proper Person. The Administrative Agent also may rely upon any statement made to
it orally or by telephone or fax and believed by it to be made by the proper
Person, and shall not incur any liability for relying thereon. The
Administrative Agent may consult with legal counsel (who may be counsel for the
Guarantors), independent accountants and other experts selected by it,

                                      E-85
<PAGE>   43
and shall not be liable for any action taken or not taken by it in accordance
with the advice of any such counsel, accountants or experts.

                  SECTION 9.05. Use of Sub-Agents. The Administrative Agent may
perform any and all its duties and exercise its rights and powers by or through
any one or more sub-agents appointed by the Administrative Agent. The
Administrative Agent and any such sub?agent may perform any and all its duties
and exercise its rights and powers through their respective Related Parties. The
exculpatory provisions of the preceding paragraphs shall apply to any such
sub-agent and to the Related Parties of the Administrative Agent and any such
sub-agent, and shall apply to their respective activities in connection with the
syndication of the credit facilities provided for herein as well as activities
as Administrative Agent.

                  SECTION 9.06. Resignation. Subject to the appointment and
acceptance of a successor Administrative Agent as provided in this paragraph,
the Administrative Agent may resign at any time by notifying the Lenders and the
Borrowers. Upon any such resignation, the Required Lenders shall have the right,
subject to the consent of the Borrowers (provided that no Event of Default has
occurred and is continuing and that such consent is not to be unreasonably
withheld), to appoint a successor, which successor shall not be domiciled in a
Tax Haven Jurisdiction. If no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the retiring Administrative Agent gives notice of its resignation, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, subject to the consent of the Borrowers (provided that no
Event of Default has occurred and is continuing and that such consent is not to
be unreasonably withheld), which shall be a bank with an office in New York City
or an Affiliate of any such bank, which successor shall not be domiciled in a
Tax Haven Jurisdiction. Upon the acceptance of its appointment as Administrative
Agent hereunder by a successor, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder. The fees payable by the Borrowers to
a successor Administrative Agent shall be, without duplication, the same as
those payable to its predecessor unless otherwise agreed between the Borrowers
and such successor. After the Administrative Agent's resignation hereunder, the
provisions of this Article and 10.03 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
Administrative Agent.

                  SECTION 9.07. Non-reliance on Administrative Agent. Each
Lender acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it shall from time
to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement, any other Loan Document or any
related agreement or any document furnished hereunder or thereunder.

                  SECTION 9.08. Consent to Modification, etc. Except as
otherwise provided in Section 10.02(b) with respect to this Agreement, the
Administrative Agent may, with the prior consent of the Required Lenders (but
not otherwise), consent to any modification, supplement or waiver under any of
the Loan Documents.

                                   ARTICLE X

                  Any party hereto may change its address or fax number for
notices and other communications hereunder by notice to the other parties hereto
(or, in the case of any such change by a Lender, by notice to the Borrowers and
the Administrative Agent). All notices and other communications given to any
party hereto in accordance with the provisions of this Agreement shall be deemed
to have been given on the date of receipt.

                  With respect to any notices given by the Administrative Agent
or any Lender to the Borrowers under any Loan Document, such notifying party
shall provide copies of such notice to Telesystem International Wireless, Inc.
at 1000 de La Gauchetiere Street West, Montreal, Quebec, H3B 4W5 Canada,
Attention of Chief Financial Officer (Fax No. 514-673-8470; Telephone No.
514-673-8497) and to the Parent at SCN Quadra 03 Bloco A - Sobreloja, 70713-000
Brasilia-DF , Attention of the Vice President of Finance (Fax No. 55 61 429
5626; Telephone No. 55 61 429 5600); provided that the failure to provide any
such copies shall neither impose any liability on the notifying party nor impair
the validity of any notice to any Borrower if such notice was provided in
accordance with the other provisions of this Section 10.01.

                  SECTION 10.02. Waivers; Amendments.

                  (a) No Deemed Waivers; Remedies Cumulative. No failure or
delay by the Administrative Agent or any Lender in exercising any right or power
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any abandonment or discontinuance of
steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of
the Administrative Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provision of this Agreement or consent to any departure by any Guarantor
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan shall not
be construed as a waiver of any Default, regardless of whether the
Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time.

                  (b) Amendments. Neither this Agreement nor any provision
hereof may be waived, amended or modified except pursuant to an agreement or
agreements in writing entered into by the Parent, each Borrower and the Required
Lenders or by the Parent, each Borrower and the Administrative Agent with the
consent of the Required Lenders; provided that no such agreement shall (i)
increase any Commitment of any Lender without the written consent of such
Lender, (ii) reduce the principal amount of any Loan or reduce the rate of
interest thereon, or reduce any fees payable hereunder, without the written
consent of each Lender affected thereby, (iii) postpone the scheduled date of
payment of the principal amount of any Loan, or any interest thereon, or any
fees payable hereunder, or reduce the amount of, waive or excuse any such
payment, or postpone the scheduled date of expiration of any Commitment, without
the written consent of each Lender affected thereby, (iv) alter the manner in
which payments or prepayments of principal, interest or other amounts hereunder
shall be applied as among the Lenders, without the written consent of each
Lender, or (v) change any of the provisions of this Section or the definition of
the term "Required Lenders" or any other provision hereof specifying the number
or percentage of Lenders required to waive, amend or modify any rights hereunder
or make any determination or grant any consent

                                      E-87
<PAGE>   45
hereunder, without the written consent of each Lender; and provided further that
no such agreement shall amend, modify or otherwise affect the rights or duties
of the Administrative Agent hereunder without the prior written consent of the
Administrative Agent.

                  Anything in this Agreement to the contrary notwithstanding, no
waiver or modification of any provision of this Agreement that has the effect
(either immediately or at some later time) of enabling the Borrowers to satisfy
a condition precedent to the making of a Loan shall be effective against any
Lender unless the Required Lenders shall have concurred with such waiver or
modification.

                  SECTION 10.03. Expenses; Indemnity; Damage Waiver.

                  (a) Costs and Expenses. The Guarantors shall pay (i) all
reasonable out-of-pocket expenses and documentation fees (both external fees
and, with respect to the Political Risk Insurance Agreement and the Arranger
Participation Agreement, internal legal fees charged by EDC to any party
thereto) incurred by each of the Administrative Agent and each of EDC and
BankBoston N.A., each in its capacity as an Arranger, including the reasonable
fees, charges and disbursements of counsel for the Administrative Agent, in
connection with the syndication of the credit facilities provided for herein,
the preparation and administration of this Agreement and the other Loan
Documents or any amendments, modifications or waivers of the provisions hereof
or thereof (whether or not the transactions contemplated hereby or thereby shall
be consummated) and (ii) all reasonable out-of-pocket expenses incurred by the
Administrative Agent or any Lender or Arranger, including the fees, charges and
disbursements of any counsel for the Administrative Agent, any Lender or any
Arranger, in connection with the enforcement or protection of its rights in
connection with this Agreement and the other Loan Documents, including its
rights under this Section, or in connection with the Loans made hereunder,
including in connection with any workout, restructuring or negotiations in
respect thereof. Notwithstanding anything to the contrary in this Section
10.03(a), the Guarantors shall be obligated to pay only the reasonable fees and
expenses of a single special counsel in New York and any necessary single local
counsel in Brazil to the Administrative Agent, the Lenders and the Arrangers and
their respective Affiliates, collectively.

                  (b) Indemnification by the Guarantors. Notwithstanding any
exceptions or exclusions with respect to the representations and warranties made
by each of the Guarantors in Article IV, the Guarantors shall indemnify the
Administrative Agent, each Lender and each Arranger (each such Person being
called an "Indemnitee") against, and to hold each Indemnitee harmless from, any
and all losses, claims, damages, liabilities and related expenses, including the
reasonable fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection
with, or as a result of any actual or prospective claim, litigation,
investigation or proceeding relating to (i) the execution or delivery of this
Agreement or any agreement or instrument contemplated hereby, the performance by
the parties hereto of their respective obligations hereunder or the consummation
of the Transactions or any other transactions contemplated hereby or (ii) any
Loan or the use of the proceeds therefrom, whether based on contract, tort or
any other theory and regardless of whether any Indemnitee is a party thereto;
provided that (A) such indemnity shall not, as to any Indemnitee, be available
to the extent that such losses, claims, damages, liabilities or related expenses
are determined to have resulted from the gross negligence or willful misconduct
of such Indemnitee and (B) the Guarantors shall have no obligation to any
Indemnitee hereunder in connection with (x) any claim, litigation, investigation
or proceeding between solely two or more Indemnitees (including any claim,
litigation, investigation or proceeding between solely two or more parties to
the Arranger Participation Agreement) except to the extent arising solely
because of any Default by any Guarantor and (y) any waiver, release or
settlement entered into by any Indemnitee without the prior written consent of
the Guarantors solely to the extent such release admits criminal negligence or
liability. Each Indemnitee agrees that it shall consult in good faith with the
Guarantors with respect to any waiver, release or settlement to be entered into
by such Indemnitee during negotiation thereof and for which such Indemnitee
seeks indemnification pursuant to this Section. Except with respect to any
claim, litigation, investigation or proceeding between two or more Indemnitees
for which the Guarantors are required to indemnify pursuant to this Section, the
Guarantors shall be obligated to pay only the reasonable fees and expenses of a
single special New York counsel and any necessary single local counsel in Brazil
to the Indemnitees collectively for each such claim, investigation or
proceeding.

                  (c) Reimbursement by Lenders. To the extent that the Borrowers
fail to pay any amount required to be paid by it to the Administrative Agent or
any Lender under paragraph (a) or (b) of this Section, each Lender severally
agrees to pay to the Administrative Agent such Lender's Applicable Percentage
(determined as of the time that the applicable unreimbursed expense or indemnity
payment is sought) of such unpaid amount; provided that the unreimbursed expense
or indemnified loss, claim, damage, liability or related expense, as the case
may be, was incurred by or asserted against the Administrative Agent in its
capacity as such or any Lender.

                  (d) Waiver of Consequential Damages, Etc. To the extent
permitted by applicable law, the Borrowers shall not assert, and hereby waive,
any claim against any Indemnitee, on any theory of liability, for special,
indirect, consequential or punitive damages (as opposed to direct or actual
damages) arising out of, in connection with, or as a result of, this Agreement
or any agreement or instrument contemplated hereby, the Transactions, any Loan
or the use of the proceeds thereof.

                  (e) Payments. All amounts due under this Section shall be
payable not later than 30 days after demand therefor.

                  SECTION 10.04. Successors and Assigns.

                  (a) Assignments Generally. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby, except that no Guarantor may
assign or otherwise transfer any of its rights or obligations hereunder without
the prior written consent of each Lender (and any attempted assignment or
transfer by any Guarantor without such consent shall be null and void). Nothing
in this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns
permitted hereby and, to the extent expressly contemplated hereby, the Related
Parties of each of the Administrative Agent and the Lenders) any legal or
equitable right, remedy or claim under or by reason of this Agreement.

                  (b) Assignments by Lenders. Notwithstanding anything herein to
the contrary, no Lender may assign all or a portion of its rights and
obligations pursuant to this Section 10.04(b) unless (A) an Event of Default has
occurred and is continuing, (B) payments of interest hereunder by the Borrowers
to the Lenders are subject to withholding tax in Brazil at a rate at least equal
to the rate of withholding tax payable by a Brazilian borrower to Foreign
Lenders resident in a jurisdiction that does not have a tax treaty with Brazil,
or (C) such assignment shall not subject interest payments to such assignee to
withholding tax in Brazil. Subject to the immediately preceding sentence and the
provisions of the Arranger Participation Agreement, any Lender may assign to one
or more financial institutions all or a portion of its rights and obligations
under this Agreement (including all or a portion of its Commitments and the
Loans at the time owing to it); provided that (i) except in the case of an
assignment to a Lender, an Arranger, or a financial institution that is a member
of the Federal Reserve System of the United States of America and that has
combined capital and surplus of not less than $500,000,000, each of the
Borrowers and the Administrative Agent must give their prior written consent to
such assignment (which consent shall not be unreasonably withheld), (ii) except
in the case of an assignment to a Lender, an Arranger, or a pledge or assignment
to a Federal Reserve Bank of the United States, or an assignment of the entire
remaining amount of the assigning Lender's Commitment(s) and outstanding Loans,
the amount of the Commitment(s) and outstanding principal amount of Loans of the
assigning Lender (x) subject to each such assignment and (y) retained after
giving effect to such assignment (in each case determined as of the date the
Assignment and Acceptance with respect to such assignment is delivered to the
Administrative Agent) shall not be less than $3,500,000 and increments of
$500,000 thereof unless each of the Borrowers and the Administrative Agent
otherwise consent, (iii) each partial assignment shall be made as an assignment
of a proportionate part of all the assigning Lender's rights and obligations
under this Agreement and (iv) the parties to each assignment shall execute and
deliver to the Administrative Agent an Assignment and Acceptance, together with
a processing and recordation fee of $2,500; provided further that any consent of
any Borrower otherwise required under this paragraph shall not be required if an
Event of Default has occurred and is continuing. Upon acceptance and recording
pursuant to paragraph (d) of this Section, from and after the effective date
specified in each Assignment and Acceptance, the assignee thereunder shall be a
party hereto and, to the extent of the interest assigned by such Assignment and
Acceptance, have the rights and obligations of a Lender under this Agreement,
provided that no assignee shall be entitled to receive any

                                      E-89
<PAGE>   47
greater amount pursuant to Sections 2.11, 2.12 or 2.13 than the assigning Lender
would have been entitled to receive in respect of the interest assigned by such
Assignment and Acceptance had no such assignment occurred; and the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all of the assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Sections
2.11, 2.12, 2.13 and 10.03). Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this paragraph shall
be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with paragraph (e) of
this Section.

                  (c) Maintenance of Register by the Administrative Agent. The
Administrative Agent shall maintain at one of its offices a copy of each
Assignment and Acceptance delivered to it and a register for the recordation of
the names and addresses of the Lenders, and the Commitments of, and principal
amount of the Loans owing to, each Lender pursuant to the terms hereof from time
to time (the "Register"). The entries in the Register shall be conclusive, and
the Borrowers, the Administrative Agent and the Lenders may treat each Person
whose name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary. The Register shall be available for inspection by the Borrowers and
any Lender, at any reasonable time and from time to time upon reasonable prior
notice.

                  (d) Effectiveness of Assignments. Upon its receipt of a duly
completed Assignment and Acceptance executed by an assigning Lender and an
assignee, the assignee's completed Administrative Questionnaire (unless the
assignee shall already be a Lender hereunder), the processing and recordation
fee referred to in paragraph (b) of this Section and any written consent to such
assignment required by paragraph (b) of this Section, the Administrative Agent
shall accept such Assignment and Acceptance and record the information contained
therein in the Register. No assignment shall be effective for purposes of this
Agreement unless it has been recorded in the Register as provided in this
paragraph.

                  (e) Participations. Any Lender or Arranger may, without the
consent of the Borrowers or the Administrative Agent, sell participations to one
or more financial institutions (a "Participant") in all or a portion of such
Person's rights and obligations under this Agreement and the other Loan
Documents (including all or a portion of its Commitments and the Loans owing to
it); provided that (i) such Person's obligations under this Agreement and the
other Loan Documents shall remain unchanged, (ii) such Person shall remain
solely responsible to the other parties hereto or thereto for the performance of
such obligations and (iii) the Borrowers, the Administrative Agent and the other
Lenders and Arrangers shall continue to deal solely and directly with such
Person in connection with such Person's rights and obligations under this
Agreement and the other Loan Documents. Any agreement or instrument pursuant to
which a Lender or Arranger sells such a participation shall provide that such
Person shall retain the sole right to enforce this Agreement and the other Loan
Documents and to approve any amendment, modification or waiver of any provision
of this Agreement or any other Loan Document; provided that such agreement or
instrument may provide that such Person will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in the
first proviso to Section 10.02(b) that affects such Participant. No Participant
shall be entitled to receive any greater amount pursuant to Section 2.11, 2.12
or 2.13 than the selling Lender or Arranger would have been entitled to receive
in respect of the interest sold to such Participant had no such sale occurred.
For the purposes hereunder, each Arranger shall be deemed to be a Participant,
except that, notwithstanding the preceding sentence, each Arranger shall be
entitled to the benefits of Sections 2.11, 2.12, 2.13 (in each case, subject to
Section 2.15) and 10.03 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to paragraph (b) of this Section.

                  (f) Certain Pledges. Notwithstanding anything herein to the
contrary, any Lender may at any time pledge or assign a security interest in all
or any portion of its rights under this Agreement to a Federal Reserve Bank of
the United States in support of borrowings made by such Lender from such Federal
Reserve Bank, and the other clauses of this Section shall not apply to any such
pledge or assignment of a security interest; provided that no such pledge or
assignment of a security interest shall release a Lender from any of its
obligations hereunder or substitute any such assignee for such Lender as a party
hereto.

                  (g) Assignments to a Borrower or Affiliates. Notwithstanding
anything in this Section to the contrary, upon the request of any Borrower, each
Lender and Arranger severally agrees to assign or participate all or a portion
of its interest in any Loan to such Borrower or any of its Affiliates at a price
equal to the principal amount of such Loans assigned or in which such
participation is made plus accrued and unpaid interest thereon to the date of
such assignment or participation, provided that (i) such Borrower or such
Affiliate shall have no voting rights with respect to such assigned or
participated interest in connection with any decision or action undertaken by
the Administrative Agent, any Lender or Arranger hereunder or under any Loan
Document and (ii) such assignment or participation shall be made pro-rata among
all the Lenders and Arrangers in proportion to (A) in the case of an Arranger,
the principal amount of the participations held by such Arranger or (B) in the
case of a Lender, the principal amount of the Loans made by such Lender and not
subject to a participation with an Arranger, all as determined by the
Administrative Agent with notice thereof to such Borrower. In any other event,
no Lender may assign or participate any interest in any Loan held by it
hereunder to any Borrower or any of its Affiliates without the prior consent of
each Lender. For the purposes of calculating the financial covenants set forth
in Section 6.13, neither Loans that shall have been assigned to such Borrower or
any of its Affiliates nor Loans in which such Borrower or any of its Affiliates
shall hold a participation, in each case pursuant to this Section 10.04(g),
shall constitute Indebtedness.

                  SECTION 10.05. Survival. All covenants, agreements,
representations and warranties made by each Guarantor herein and in the
certificates or other instruments delivered in connection with or pursuant to
this Agreement shall be considered to have been relied upon by the other parties
hereto and shall survive the execution and delivery of this Agreement and the
making of any Loans, regardless of any investigation made by any such other
party or on its behalf and notwithstanding that the Administrative Agent or any
Lender may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and
shall continue in full force and effect as long as the principal of or any
accrued interest on any Loan or any fee or any other amount payable under this
Agreement is outstanding and unpaid and so long as the Commitments have not
expired or terminated. The provisions of Sections 2.11, 2.12, 2.13 and 10.03 and
Article IX shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Commitments or the termination of
this Agreement or any provision hereof.

                  SECTION 10.06. Counterparts; Integration. This Agreement may
be executed in counterparts. Delivery of an executed counterpart of a signature
page to this Agreement by facsimile shall be effective as delivery of a manually
executed counterpart of this Agreement. This Agreement and any separate letter
agreements with respect to fees payable to the Administrative Agent constitute
the entire contract between and among the parties relating to the subject matter
hereof and supersede any and all previous agreements and understandings, oral or
written, relating to the subject matter hereof.

                  SECTION 10.07. Severability. Any provision of this Agreement
held to be invalid, illegal or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such invalidity, illegality
or unenforceability without affecting the validity, legality and enforceability
of the remaining provisions hereof; and the invalidity of a particular provision
in a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

                  SECTION 10.08. Right of Setoff. Subject to Section 2.14(d), if
a Event of Default pursuant to clause (a), (h), (i) or (j) of Article VIII shall
have occurred and be continuing, each Lender is hereby authorized at any time
and from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by such Lender
to or for the credit or the account of any Guarantor against any of and all the
matured obligations of such Guarantor existing under this Agreement at such time
and held by such Lender, irrespective of whether or not such Lender shall have
made any demand under this Agreement. The rights of each Lender under this
Section are in addition to other rights and remedies which such Lender may have.

                  SECTION 10.09. Governing Law; Jurisdiction; Service of
Process; Etc.

                  (a) Governing Law. This Agreement shall be construed in
accordance with and governed by the law of the State of New York.

                  (b) Submission to Jurisdiction. Each party hereto hereby
agrees that any suit, action or proceeding with respect to this Agreement, the
other Loan Documents or any judgment entered by any court in respect thereof may
be brought in the United States District Court for the Southern District of New
York, in the Supreme Court of the State of New York sitting in New York County
(including its Appellate Division), or in any other appellate court in the State
of New York, as the party commencing such suit, action or proceeding may elect
in its sole discretion; and each party hereto hereby irrevocably submits to the
jurisdiction of such courts and all appellate courts thereof for the purpose of
any such suit, action, proceeding or judgment. Each party hereto further
submits, for the purpose of any such suit, action, proceeding or judgment
brought or rendered against it, to the appropriate courts of the jurisdiction of
its domicile.

                  (c) Process Agent. Each of the Guarantors hereby agree that
service of all writs, process and summonses in any such suit, action or
proceeding brought in the State of New York may be made upon CT Corporation,
presently located at 111 Eighth Avenue, New York, New York 10011, U.S.A. (the
"Process Agent"), and each of the Guarantors hereby confirm and agree that the
Process Agent has been duly and irrevocably appointed as its agent and true and
lawful attorney-in-fact in its name, place and stead to accept such service of
any and all such writs, process and summonses, and agrees that the failure of
the Process Agent to give any notice of any such service of process to such
Guarantor shall not impair or affect the validity of such service or of any
judgment based thereon.

                  (d) Other Service. Nothing herein shall in any way be deemed
to limit the ability of the Administrative Agent or any Lender to serve any such
writs, process or summonses in any other manner permitted by applicable law or
to obtain jurisdiction over any Guarantor in such other jurisdictions, and in
such manner, as may be permitted by applicable law.

                  (e) Waiver of Venue. Each of the Guarantors hereby irrevocably
waive any objection that it may now or hereafter have to the laying of the venue
of any suit, action or proceeding arising out of or relating to this Agreement
or any other Loan Document brought in the Supreme Court of the State of New
York, County of New York or in the United States District Court for the Southern
District of New York, and hereby further irrevocably waives any claim that any
such suit, action or proceeding brought in any such court has been brought in an
inconvenient forum.

                  SECTION 10.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF
OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

                  SECTION 10.11. No Immunity. To the extent that any Guarantor
may be or become entitled, in any jurisdiction in which judicial proceedings may
at any time be commenced with respect to this Agreement or any other Loan
Document, to claim for itself or its properties or revenues any immunity from
suit, court jurisdiction, attachment prior to judgment, attachment in aid of
execution of a judgment, execution of a judgment or from any other legal process
or remedy relating to its obligations under this Agreement or any other Loan
Document, and to the extent that in any such jurisdiction there may be
attributed such an immunity (whether

                                      E-92
<PAGE>   50
or not claimed), such Guarantor hereby irrevocably agrees not to claim and
hereby irrevocably waives such immunity to the fullest extent permitted by the
laws of such jurisdiction.

                  SECTION 10.12. Judgment Currency.

                  (a) This is an international loan transaction in which the
specification of dollars and payment in New York is of the essence, and the
obligations of the Guarantors under this Agreement to make payment to (or for
the account of) a Lender in dollars shall not be discharged or satisfied by any
tender or recovery pursuant to any judgment expressed in or converted into any
other currency or in another place except to the extent that such tender or
recovery results in the effective receipt by such Lender in New York of the full
amount of dollars payable to such Lender under this Agreement. If for the
purpose of obtaining judgment in any court it is necessary to convert a sum due
hereunder in dollars into another currency (in this Section called the "judgment
currency"), the rate of exchange that shall be applied shall be that at which in
accordance with normal banking procedures the Administrative Agent could
purchase such dollars at the principal office of the Administrative Agent in New
York City with the judgment currency on the Business Day next preceding the day
on which such judgment is rendered. The obligation of the Guarantors in respect
of any such sum due from it to the Administrative Agent or any Lender hereunder
or under any other Loan Document (in this Section called an "Entitled Person")
shall, notwithstanding the rate of exchange actually applied in rendering such
judgment, be discharged only to the extent that on the Business Day following
receipt by such Entitled Person of any sum adjudged to be due hereunder in the
judgment currency the Administrative Agent could purchase dollars at the office
of the Administrative Agent in New York City in accordance with normal banking
procedures with the amount of the judgment currency so adjudged to be due; and
each Guarantor hereby, as a separate obligation and notwithstanding any such
judgment, agrees to indemnify such Entitled Person against, and to pay such
Entitled Person on demand, in dollars, the amount (if any) by which the sum
originally due to such Entitled Person in dollars hereunder exceeds the amount
of the dollars so purchased and transferred.

                  (b) It is expressly agreed by each Guarantor hereunder that
payment in immediately available and freely transferable dollars at the time and
the place provided in this Agreement is the essence of this Agreement and
payment in any other currency or manner shall not be deemed to satisfy the
obligations of such Guarantor hereunder, whether or not the ability of such
Guarantor to make such payment is or remains within its control or shall be
subject to a force majeure. Upon the occurrence of a Dollar Restriction, each
Guarantor hereby agrees to promptly take all steps and efforts necessary or
appropriate to effectuate the conversion and/or transfer of the amount of local
currency then necessary to provide for the Affected Payment then due and payable
in respect of the Loan, all in accordance with the laws, regulations and
procedures then in effect in Brazil, including, without limitation, by payment
as then may be directed by the Lender of such amount to a Brazilian currency
account maintained by the Administrative Agent at BankBoston Banco Multiplo S.A.
or at the Central Bank or at such other bank or depositary as specified by the
Administrative Agent, and the entering into by such Borrower of any foreign
exchange agreements then required by the laws, regulations or procedures of the
Central Bank. The amount of any such local currency payment shall be determined
by the PTAX 800 Rate, on the Affected Payment Date (as defined below) or, if the
PTAX 800 Rate ceases to exist, at the rate obtained through another customary
legal channel for transactions of the type contemplated in this Agreement, or,
if there is no such rate replacing the PTAX 800 Rate, such rate as is determined
by BankBoston N.A. in good faith.

                  Any payment in Brazilian currency in accordance with the
provision of this Clause shall not be deemed to discharge any Borrower's
obligation to make payment in U.S. dollars of the amount then due and payable to
which such payment in Brazilian currency relates unless and until the
Administrative Agent shall have received the full amount then due hereunder in
immediately available and freely transferable dollars at the place and in the
manner provided for herein.

                  The term "Affected Payment Date" means an Interest Payment
Date or the Maturity Date under this Agreement.

                  SECTION 10.13. Use of English Language. This Agreement has
been negotiated and executed in the English language. All certificates, reports,
notices and other documents and communications given

                                      E-93
<PAGE>   51
or delivered pursuant to this Agreement (including any modifications or
supplements hereto) shall be in the English language, or if not in the English
language and to the extent requested by the Administrative Agent, accompanied by
a certified English translation thereof other than documents required to be
delivered pursuant to (i) Section 6.01(a), (b)(i) and (ii), (d) or (e) for which
an English language translation shall be delivered within 15 days thereafter and
(ii) Section 5.01. Except in the case of laws or official communications of any
Governmental Authority of Brazil, in the case of any document originally issued
in a language other than English, the English language version of any such
document shall for purposes of this Agreement, and absent manifest error,
control the meaning of the matters set forth therein.

                  SECTION 10.14. Headings. Article and Section headings and the
Table of Contents used herein are for convenience of reference only, are not
part of this Agreement and shall not affect the construction of, or be taken
into consideration in interpreting, this Agreement.

                  SECTION 10.15. Treatment of Certain Information;
Confidentiality.

                  (a) Treatment of Certain Information. Each Guarantor
acknowledges that from time to time financial advisory, investment banking and
other services may be offered or provided to such Guarantor (in connection with
this Agreement or otherwise) by any Lender or by one or more Affiliates of such
Lender and each Guarantor hereby authorizes each Lender to share any information
delivered to such Lender by such Guarantor pursuant to this Agreement, or in
connection with the decision of such Lender to enter into this Agreement, to any
such Affiliate, it being understood that any such Affiliate receiving such
information shall be bound by the provisions of paragraph (b) of this Section as
if it were a Lender hereunder. Such authorization shall survive the repayment of
the Loans, the expiration or termination of the Commitments or the termination
of this Agreement or any provision hereof.

                  (b) Confidentiality. Each of the Administrative Agent and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (i) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors in each case on a need to know basis (it being understood
that the Persons to whom such disclosure is made will be informed of the
confidential nature of such Information and instructed to keep such Information
confidential), (ii) to the extent requested by any regulatory authority, (iii)
to the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (iv) to any other party to this Agreement, (v) in
connection with the exercise of any remedies hereunder or under any other Loan
Document or any suit, action or proceeding relating to this Agreement or any
other Loan Document or the enforcement of rights hereunder or thereunder, (vi)
subject to an agreement containing provisions substantially the same as those of
this paragraph, to any assignee of or Participant in, or any prospective
assignee of or Participant in, any of its rights or obligations under this
Agreement, (vii) with the consent of the Guarantors, (viii) to the Insurer or
(ix) to the extent such Information (x) becomes publicly available other than as
a result of a breach of this paragraph or (y) becomes available to the
Administrative Agent, any Arranger or any Lender on a nonconfidential basis from
a source other than any Guarantor. For the purposes of this paragraph,
"Information" means, with respect to any Guarantor, all information received
from any Guarantor or its Related Parties relating to such Guarantor or its
business, including, without limitation, the reports delivered pursuant to
Sections 6.01(e) and 6.01(f) hereof, other than any such information that is
available to the Administrative Agent or any Lender on a nonconfidential basis
prior to disclosure by or on behalf of such Guarantor; provided that, in the
case of information received from such Guarantor or its Related Parties after
the date hereof, other than the reports delivered pursuant to Sections 6.01(e)
and 6.01(f) hereof, such information is clearly identified at the time of
delivery as confidential. Any Person required to maintain the confidentiality of
Information as provided in this Section shall be considered to have complied
with its obligation to do so if such Person has exercised the same degree of
care to maintain the confidentiality of such Information as such Person would
accord to its own confidential information.
