conditions of this Agreement, to make a loan (the "Loan") to the Borrower in

delivery of a Participation Agreement, consist of:

                  (a) an A Loan, to be funded by IDB from its ordinary capital

IDB, in Dollars, upon receipt of a Disbursement Request from the Borrower and
the Borrower's compliance with the provisions of Section 6 hereof, to the credit

substantially in the form of Exhibit B and upon receipt of the proceeds of each
Disbursement or any portion thereof, the Borrower shall execute and deliver to
IDB within three Business Days after the Disbursement a receipt therefor
substantially in the form of Exhibit C. In the event that a Participation
Agreement has been executed and delivered prior to the Commitment Termination
Date, IDB shall have no obligation to make a Disbursement of the B Loan except
to the extent that each Participant shall have made available to IDB, in
immediately available funds, its proportionate share of such Disbursement in
accordance with the Participation Agreement to which it is a party.

                  2.03 Changes of the Commitment.

                  (a) Voluntary Reduction of Commitment. The Borrower shall have
the right only on one occasion during the term of this Agreement to terminate or
reduce the unutilized amount of the Commitment; provided that (i) the Borrower
shall give notice of each such termination or reduction as provided in Section
4.04, (ii) a partial reduction shall be in an amount at least equal to
$1,000,000 and (iii) the Borrower shall demonstrate to the written satisfaction
of IDB, either (A) that sufficient available permitted sources of funds exist to
achieve Completion of Network Construction or (B) that additional funds are not
needed to achieve Completion of Network Construction.

                  (b) Automatic Termination of Commitment. The Commitment shall
be automatically reduced to zero at the close of business on the Commitment
Termination Date. Any borrowing hereunder shall be deemed to reduce
automatically the Commitment in the amount of such borrowing. Amounts borrowed,
and subsequently repaid or prepaid, may not be reborrowed.

                  (c) No Reinstatement of Commitment. The Commitment once
terminated or reduced may not be reinstated.

                  2.04 Fees.

                  (a) Commitment Fee. The Borrower shall pay to IDB a commitment
fee on the daily average unutilized amount of the Commitment, for the period
from and including the date hereof to but not including the earlier of the date
the Commitment is terminated and the Commitment Termination Date, at a rate per
annum equal to 0.75%. Accrued commitment fee shall be payable on each Interest
Payment Date including the Interest Payment Date first following the earlier of
the date the Commitment is terminated and the Commitment Termination Date.

                  (b) Front-End Fee. The Borrower shall pay to IDB a front-end
fee in an amount equal to $250,000 on the date of the initial Disbursement of
the Loan.

                  (c) Administration Fee. In the event that a Participation
Agreement is executed and delivered at any time during the term of this
Agreement, the Borrower shall pay to IDB on the first Interest Payment Date
following such execution and delivery of such Participation Agreement and each
anniversary thereof throughout the term of this Agreement an administration fee
in an amount equal to the lesser of (i) $25,000 and (ii) the product of (A)
$5,000 multiplied by (B) the number of Participants. The fee referred to in the
preceding sentence shall be in addition to the Borrower's obligation to pay for
any costs incurred under the Paying Agency Agreement and to reimburse any
consultants' fees in connection with such administrative role.

                  (d) Underwriting Fee. Upon the execution and delivery of any
Participation Agreement, the Borrower shall pay to the Participant party to such
Participant Agreement an amount equal to 0.5% of the B Loan acquired pursuant
thereto.

                  2.05 The Notes.

to be made by IDB on such date. The rights of IDB under this Agreement, and
under each of the other Transaction Documents, shall not be limited, reduced or
otherwise affected by the existence of, or any action with respect to, the
Notes; provided, however, that any reduction (by repayment, prepayment or
otherwise) in the principal amount of any Disbursement hereunder or repayment or
prepayment of the face amount of the Notes, as the case may be, shall discharge
pro tanto the equivalent face amount of the Notes or, as the case may be, the
corresponding principal amount of any Disbursement hereunder.

                  (b) The Borrower shall re-execute the Notes as and when
requested to do so by IDB or the Custodian for the benefit of IDB and in any
event upon ten month intervals of the

date of each Disbursement; it being understood that IDB or the Custodian may
re-execute the Notes pursuant to the authority contained in the Power of
Attorney described in the IDB Custodian Agreement.

                  (c) Upon the payment in full of the obligations evidenced
thereby, IDB shall cancel, and return, or instruct the Custodian to cancel and
return to the Borrower, each such Note so paid in full.

                  (d) IDB shall not be entitled to make a demand for payment
under any Note unless the amounts so demanded are then due and payable (whether
at scheduled maturity, by mandatory prepayment, acceleration or otherwise) by
the Borrower in accordance with the terms of this Agreement. If IDB exercises
any right in any court in Chile under any Note delivered pursuant to this
Agreement, it shall not be required for such purpose to evidence to the Borrower
or any other Person that such Notes represent obligations of the Borrower under
this Agreement or any other Person under any other Transaction Document nor that
any condition herein or therein has been fulfilled.

                  2.06 Optional and Mandatory Prepayments. The parties hereto
agree that any optional or mandatory prepayment of the Loan shall be made in
accordance with Section 2.05 or 2.06, as the case may be, of the Common
Agreement.

the prepayment fees described in Sections 2.05 and 2.06 of the Common Agreement,
if the Loan has been converted to a fixed rate of interest loan, then, on the
date of any prepayment of the Loan in accordance with Section 2.05 or Section
2.06 of the Common Agreement, the Borrower shall pay a premium, in Dollars, in
an amount equal to the positive difference, if any, between the Net Present
Value of the Anticipated Income Stream and the Net Present Value of the
Available Income Stream or, in the case of a partial prepayment, the same
proportion of such difference as the proportion of the amount of the Loan to be
prepaid to the amount of the Loan then outstanding. The determination by IDB of
the prepayment premium shall be final and conclusive unless shown by the
Borrower to have involved manifest error.

                  Section 3. Payments of Principal and Interest.

                  3.01 Repayment of Loan. The Borrower hereby promises to pay on

of the aggregate principal amount of the Loan outstanding on the date following
the date of the final Disbursement of the Loan hereunder, as follows:

the execution and delivery of any Participation Agreement. IDB shall notify the
Borrower in writing the portion of each subsequent installment of principal
which should be paid to IDB and to each Participant.

                  3.02 Interest.

                  (a) Provisions Specific to the A Loan. Subject to Sections
3.03 and 3.04, the Borrower shall pay interest on the outstanding principal
amount of the A Loan from time to time as follows:

                  (i) During each Interest Period, the A Loan (or, in respect of
         the first Interest Period of each Disbursement, the amount of that
         Disbursement) shall bear interest at the A Loan Interest Rate (as
         determined under Section 3.02(a)(ii) below) for that Interest Period;

                  (ii) The A Loan Interest Rate shall equal the sum of LIBOR
         plus the Applicable Margin. The A Loan Interest Rate will be reset
         semiannually on each Interest Rate Determination Date during each year,
         will apply to the total outstanding disbursed amount of the A Loan at
         such dates and will accrue for the then relevant Interest Period
         between the immediately succeeding Interest Payment Date and the next
         succeeding Interest Payment Date. For Disbursements made on a date
         other than an Interest Payment Date, interest will accrue from the
         Disbursement Date until the next Interest Payment Date at the interest
         rate prevailing at the Interest Rate Determination Date plus the
         Applicable Margin corresponding to the monthly quoted LIBOR interest
         period equal to or greater than the period from the Disbursement to the
         next Interest Payment Date;

                  (iii) On each Interest Rate Determination Date for any
         Interest Period, IDB shall, in accordance with the relevant subsection
         above, determine the A Loan Interest Rate applicable to that Interest
         Period and promptly notify the Borrower thereof; and

                  (iv) The determination by IDB, from time to time, of the A
         Loan Interest Rate shall be final and conclusive and shall be binding
         on the Borrower (absent manifest error).

                  (b) Provisions Specific to the B Loan. Subject to Sections
3.03 and 3.04, the Borrower shall pay interest on the outstanding principal
amount of the B Loan from time to time as follows:

                  (i) The B Loan (or, in respect of the first Interest Period of
         each Disbursement, the amount of that Disbursement) shall bear interest
         at the B Loan Interest Rate (as determined under Section 3.02(b)(ii)
         below) for that Interest Period;

                  (ii) The B Loan Interest Rate shall equal the sum of LIBOR
         plus the Applicable Margin. The B Loan Interest Rate will be reset
         semiannually on each Interest Rate Determination Date during each year,
         will apply to the total outstanding disbursed amount of the B Loan at
         such dates and will accrue for the then relevant Interest Period
         between the immediately succeeding Interest Payment Date and the next
         succeeding Interest Payment Date. For Disbursements made on a date
         other than an Interest Payment

         Date, interest will accrue from the Disbursement Date until the next
         Interest Payment Date at the interest rate prevailing at the Interest
         Rate Determination Date plus the Applicable Margin corresponding to the
         monthly LIBOR interest period equal to or greater than the period from
         the Disbursement to the next Interest Payment Date:

                  (iii) On each Interest Rate Determination Date for any
         Interest Period. IDB shall, in accordance with the relevant subsection
         above, determine the B Loan Interest Rate applicable to that Interest
         Period and promptly notify the Borrower thereof; and

                  (iv) The determination by IDB, from time to time, of the B
         Loan Interest Rate shall be final and conclusive and shall be binding
         on the Borrower (absent manifest error).

                  3.03 Late Charges.

                  (a) Any principal of the Loan that is not paid by the Borrower
when due hereunder and, to the extent permitted by Applicable Law, any interest
on the Loan that is not paid by the Borrower when due hereunder, shall bear
interest, payable on demand, for each day from and including the date payment
thereof was due to but excluding the date actual payment is received by IDB at a
rate per annum equal to the sum of (i) two percent (2%) per annum (or such lower
rate as may be required by Applicable Law) plus (ii) the rate of interest
(including the Applicable Margin) otherwise provided in Section 3.02(a) (in the
case of the principal of, and interest on, the A Loan) or Section 3.02(b) (in
the case of principal of, and interest on, the B Loan).

                  (b) All fees and other Obligations (other than principal of,
and interest on, the A Loan and the B Loan) that are not paid by the Borrower
when due hereunder or under any other applicable Financing Document shall bear
interest, payable on demand, for each day from and including the date payment
thereof was due to but excluding the date actual payment is received by IDB at a
rate per annum equal to the sum of (i) two percent (2%) per annum (or such lower
rate as may be required by Applicable Law) plus (ii) the rate of interest
(including the Applicable Margin) provided in Section 3.02(a).

                  3.04 Maximum Interest Rate.

                  (a) No provision of this Agreement shall require, or be
construed as requiring, the Borrower to pay interest or other charges on the
Loan at a rate exceeding the maximum rate of interest or other charges permitted
by Applicable Law.

                  (b) If the amount of interest payable on the Loan on any
Interest Payment Date in respect of the immediately preceding Interest Period,
computed pursuant to Section 3.02(a) or Section 3.02(b), as the case may be,
would exceed the maximum amount permitted by Applicable Law, the amount of
interest or other charges payable on such Interest Payment Date shall be
automatically reduced to such maximum permissible amount.

                  (c) If the amount of interest payable on the Loan for any
Interest Period is reduced pursuant to Section 3.04(b) and the amount of
interest payable on the Loan for any subsequent Interest Period, computed
pursuant to Section 3.02(a) or Section 3.02(b), as the case

                               IDB Loan Agreement

<PAGE>

                                     - 10 -

may be, would be less than the maximum amount permitted by Applicable Law, then
the amount of interest payable on the Loan for such subsequent Interest Period
shall be automatically increased to such maximum permissible amount; provided
that at no time shall the aggregate amount of interest paid pursuant to this
Section 3.04(c) exceed the aggregate amount by which interest payable on the
Loan has been reduced pursuant to Section 3.04(b).

                  (d) Except to the extent required pursuant to Applicable Law,
none of the fees referred to in Section 2.04, any legal fees nor any other fees,
charges or Obligations payable hereunder or under the other Transaction
Documents shall be included as interest in calculating the amount of interest
payable on the Loan.

                  3.05 Fixed Rate Option.

                  (a) The Borrower shall have the right, once during the life of
the Loan, subject to the approval of the Central Bank under Applicable Law, to
convert both the A Loan Interest Rate and the B Loan Interest Rate from
LIBOR-based variable rates to a fixed interest rate, by providing written notice
of the exercise of such conversion right to IDB (a "Conversion Notice"), not
later than thirty (30) days prior to the Interest Payment Date as of which such
conversion is to be effective. Upon such Interest Payment Date following the
delivery of such a Conversion Notice, (i) the fixed interest rate applicable to
the A Loan shall be equal to the sum of: (A) the Fixed Swap Equivalent Rate
applicable to the A Loan on the Interest Rate Determination Date, plus (B) the
Applicable Margin for the A Loan, plus (C) 1/8 of one percent (0.125%) and (ii)
the fixed interest rate applicable to the B Loan shall be equal to the sum of:
(A) the Fixed Swap Equivalent Rate applicable to the B Loan on the Interest Rate
Determination Date, plus (B) the Applicable Margin for the B Loan, plus (C) 1/8
of one percent (0.125%).

                  (b) The Borrower shall pay to IDB on the Interest Payment Date
on which such conversion is to be effective a conversion fee of 1/8 of one
percent (0.125%) on the outstanding amount of the Loan on the Interest Payment
Date as of which such conversion is to be effective.

                  Section 4. Payments; Computations; Etc.

                  4.01 Payments.

                  (a) Payments by the Borrower. Except to the extent otherwise
provided herein, all payments of principal, interest and other amounts to be

Attention: MT-Foreign Section, for credit to account of IDB-PR1, account number
04246884, or at such other account or financial institution as IDB may, from
time to time, notify the Borrower and (b) in respect of the B Loan, to such

1:00 p.m. (New York City time) will be considered for all purposes as having
been made on the next following Business Day.

                  (b) Application of Payments. All payments made by or for the
account of the Borrower under this Agreement or under the other Financing
Documents will be applied first, to all amounts then due and payable other than
principal and interest in such order as IDB may elect, second, to default
interest owing pursuant to Section 3.03, third, to interest due and payable
pursuant to Section 3.02, fourth, to principal due and payable, and lastly, to
prepayment of installments of principal in inverse order of maturity; provided,
however, that any prepayment made by the Borrower pursuant to Section 2.06(d) of
the Common Agreement shall be applied pro rata to the remaining principal
installments to be paid in accordance with Section 3.01. Notwithstanding the
foregoing, if IDB shall at any time receive less than the full amount then due
and payable to it in respect of the Obligations of the Borrower under this
Agreement or any other Financing Document, IDB shall have the right (as between
IDB and the Borrower) to allocate and apply such payment in any way or manner
and for such purpose or purposes under this Agreement or any other Financing
Document as IDB in its sole discretion shall determine, notwithstanding any
instruction that the Borrower may give to the contrary.

                  (c) Extensions to Next Business Day. If the due date of any
payment under this Agreement or the Notes would otherwise fall on a day that is
not a Business Day, such date shall be extended to the next succeeding Business
Day, and interest shall be payable for any principal so extended for the period
of such extension.

                  4.02 Computations. Interest on the Loan and the fees set forth
in Section 2.04 shall be computed on the basis of a year of 360 days and actual

                  4.04 Certain Notices. Notices by the Borrower to IDB of
terminations or reductions of the Commitment, of Disbursements and of optional
prepayments of the Loan shall be irrevocable and shall be effective only if

Business Days prior to the date of the relevant termination, reduction,
Disbursement or prepayment specified below or as otherwise acceptable to IDB:

                                     - 12 -

                  (i) IDB determines, in its reasonable judgment, that deposits
         in Dollars (in the applicable amounts) are not being offered to IDB or
         any Participant in the London interbank market for such Interest
         Period; or

                  (ii) IDB shall determine, in its reasonable judgment, that the
         LIBOR rate as determined by IDB will not adequately and fairly reflect
         the cost to IDB or any Participant of funding its portion of the IDB
         Loan for such Interest Period;

then IDB shall forthwith give notice thereof (which notice shall describe in
reasonable detail the basis for such determination) to the Borrower, whereupon
until IDB notifies the Borrower that the circumstances giving rise to such
determination no longer exist, the obligations of IDB to make the Loan (or such
Participant's portion thereof) shall be suspended until such time as IDB and the
Participants may again make the Loan or portion thereof (in which case the
provisions of the immediately succeeding paragraph shall be applicable).

                  (b) If the obligation of IDB to make the Loan (or a
Participant's obligation to make its respective portion of the B Loan), is
suspended pursuant to subsection (a), above (the portion of the Loan so
affected, an "Affected Loan"), then the Affected Loan shall be automatically
converted into a loan (as such, the "Converted Loan") which bears interest at a
rate per annum to be designated by IDB in its sole discretion (which rate will,
to the extent possible, reflect the credit spread for such Affected Loan and the
cost to IDB of funding such Converted Loan (or the cost to such Participant of
funding its portion of the Converted Loan)), whereupon all prepayments and
payments of principal which would otherwise be applied to the Affected Loan
shall be applied instead to the Converted Loan, and the Affected Loan shall be
made or continued instead as the Converted Loan.

                  5.02 Increased Costs. In the event of any change in Applicable
Law or regulation or the interpretation thereof by any Governmental Body charged
with the administration thereof occurring after the date of this Agreement which
imposes on IDB any condition regarding the making or maintaining of the Loan
which increases IDB's net incremental cost of making or maintaining the Loan
(including, without limitation, any reserve, special deposit, capital adequacy
or similar requirement and any tax (other than any tax imposed on IDB's overall
net income), duty or similar charge), IDB from time to time shall notify the
Borrower of such increased cost and the Borrower shall pay to IDB on demand an
amount equal to such increased cost (the "Maintenance Amount"). The IDB's
determination of the Maintenance Amount shall be conclusive absent clearly
demonstrable error, and IDB may use any reasonable averaging and attribution
methods in determining the Maintenance Amount.

                  5.03 Illegality. Notwithstanding anything to the contrary
contained in this Agreement, if, subsequent to the date of this Agreement, any
change is made in any Applicable Law or the interpretation or application
thereof by any Governmental Body shall make it unlawful for IDB or any
Participant to continue to maintain or to fund the Loan or the relevant
Participation or any portion thereof, the Borrower shall, upon request by IDB,
prepay promptly in full that portion of the principal amount of the Loan which
IDB advises is so affected, together with all accrued and unpaid interest and
Maintenance Amount (if any) (and, if such prepayment is not made on an Interest
Payment Date, any amount payable in respect of prepayment under Section 5.04)
thereon and other amounts payable under Section 5.04 and the right of the

                               IDB Loan Agreement

                                     - 13 -

Borrower to disbursement of that portion of the undisbursed Loan shall
terminate: provided, however, that upon a prepayment by the Borrower under this
Section 5.03. the Borrower shall not be responsible for the prepayment fees set
forth in Section 2.05(a) (vi) and Section 2.05(b) of the Common Agreement.

                  5.04 Costs. Expenses and Losses. If IDB or any Participant
shall incur costs, expenses or losses, as a result of:

                  (a) any failure by the Borrower (i) to pay any Obligations due
         under this Agreement or any other Financing Document on the due date
         therefor, (ii) to borrow in accordance with any Disbursement Request
         made pursuant to Section 2.02, (iii) to make any prepayment in
         accordance with a notice of prepayment pursuant to Section 4.04 hereof
         and Section 2.05 of the Common Agreement or (iv) to make any repayment
         or prepayment required pursuant to Section 3.01 hereof or Section 2.06
         of the Common Agreement, as the case may be, on any date other than the
         scheduled date for payment thereof; or

                  (b) any prepayment of all or any portion of the Loan on a date
         other than an Interest Payment Date;

the Borrower shall pay, in Dollars, upon request by IDB, the amount which IDB
shall notify to the Borrower as being the aggregate of such actual costs,
expenses and losses. For the purposes of the preceding sentence, "costs,
expenses or losses" shall include any interest paid or payable to cover any
unpaid amount, any "broken funding" or hedge liquidation costs, and any loss,
premium, penalty or expense which may be incurred in liquidating or employing
deposits of or borrowings from third parties in order to make, maintain or fund
the Loan or a Participation therein or any portion thereof (but in the case of a
late payment, after taking into account any late payment interest received under
Section 3.02).

                  5.05 Taxes.

                  (a) Payments to Be Made Free and Clear of Covered Taxes. The
Borrower acknowledges that under the Agreement Establishing the Inter-American
Development Bank dated December 30, 1959, IDB and its properties, assets, income
and transactions are immune from all taxes imposed by the IDB Members. All
payments on account of the principal of and interest on the Loan, fees and all
other amounts payable hereunder by the Borrower to or for account of IDB or, if
applicable, any Participant, including, without limitation, amounts payable
under paragraph (b) of this Section 5.05, shall be made free and clear of and
without reduction or liability for Covered Taxes. The Borrower will pay all
Covered Taxes, without charge to or offset against any amount due to IDB or, if
applicable, any Participant, prior to the date on which penalties attach
thereto, except for any Covered Taxes (other than Covered Taxes imposed on or in
respect of any amount payable hereunder, under the Notes or under any other
Financing Document) the payment of which is being contested in good faith and by
proper proceedings and against which adequate reserves are being maintained, so
long as no claim for such Covered Taxes is made on IDB or, if applicable, any
Participant.

                  (b) Indemnification by the Borrower. The Borrower shall
indemnify IDB and any Participant against, and reimburse IDB and any Participant
on demand for, any Covered Taxes and any loss, liability, claim or expense,
including interest, penalties and legal fees, that IDB or any Participant may
incur at any time arising out of or in connection with any failure of the
Borrower to make any payment of Covered Taxes when due.

                  (c) Gross-up of Covered Taxes. In the event that the Borrower
is required by applicable law, decree or regulation to deduct or withhold
Covered Taxes from any amounts payable on, under or in respect of this Agreement
or the Loan (including, without limitation, the Chilean income taxes referred to
in paragraph (e) of this Section 5.05), the Borrower shall promptly pay the
Person entitled to such amount such additional amounts as may be required, after
the deduction or withholding of Covered Taxes, to enable such Person to receive
from the Borrower on the due date thereof, an amount equal to the full amount
stated to be payable to such Person under this Agreement; provided that in the
event the Borrower is prevented by operation of law or otherwise from paying (or
causing to be paid) such Covered Taxes, the principal, or (as the case may be)
interest or other payment due under any Financing Document shall be increased to
such amount as may be necessary so that each recipient of any payment under any
Financing Document receives the amount such recipient would have received had no
such Covered Taxes been imposed. The foregoing provisions shall not be
applicable to taxes, duties, fees and other charges which are a direct
consequence of a Participant having its principal office in Chile or having or
maintaining a permanent office or establishment in Chile if and to the extent
that the relevant Participation is acquired by such permanent office or
establishment.

                  (d) Evidence of Payment of Covered Taxes. The Borrower shall
furnish to IDB, original or certified copies of the official tax receipts in
respect of each payment of Covered Taxes required under this Section 5.05,
within 30 days after the date such payment is made, and the Borrower shall
promptly furnish to IDB any other information, documents and receipts that IDB
may reasonably require to establish to its satisfaction that full and timely
payment has been made of all Covered Taxes required to be paid under this
Section 5.05.

                  (e) Representation as to Covered Taxes. The Borrower
represents and warrants to IDB that, on and as of the date hereof, none of this
Agreement or any of the other Financing Documents, or the execution or delivery
by the Borrower of this Agreement or any of the other Financing Documents, is
subject to any Covered Taxes, and no payment to be made by the Borrower under
this Agreement is subject to any Covered Taxes, except for stamp tax at the rate
of 1.2% applicable on the principal amounts disbursed.

                  Section 6. Conditions.

                  6.01 Initial Disbursement. The obligation of IDB to make the
initial Disbursement hereunder and the obligation of the Borrower to make any
payments hereunder is, in each case, subject to the satisfaction or waiver of
each of the conditions precedent set forth in Section 6.01 of the Common
Agreement.

                  6.02 Initial and Subsequent Disbursements. The obligation of
IDB to make any Disbursement (including the initial Disbursement) of the Loan to
the Borrower is subject to the

                               IDB Loan Agreement

<PAGE>

                                     - 15 -

                  (a) IDB may, by notice to the Borrower, suspend or cancel the
right of the Borrower to receive Disbursements hereunder, in whole or in part,
if any of the following occur:

                  (i) the initial Disbursement shall not have been made prior to
         June 18, 2000; or

                  (ii) IDB determines that a circumstance exists that could
         reasonably be expected to have a Borrower Material Adverse Effect or a
         SRT Material Adverse Effect; or

                  (iii) a Default or Event of Default has occurred and is
         continuing.

Upon the giving of such notice, any part of the Loan covered by the notice which
has not been disbursed shall be suspended or canceled, as directed by IDB in its
sole discretion. The exercise by IDB of the right of suspension shall not
preclude IDB from exercising its right of cancellation as provided herein,
either for the same or another reason, and shall not limit any other rights of
IDB under any other provision of this Agreement or any of the other Financing
Documents.

                  (b) IDB shall not be obligated to make any Disbursement
hereunder if it determines at the time of such proposed Disbursement that it
does not have access (for reasons outside of its control) to appropriate funding
sources.

                  (c) The Commitment Fee applicable to any undisbursed portion
of the Loan will continue to accrue and be payable during any suspension of
IDB's obligation to make Disbursements pursuant to Section 6.03(a) and Section
6.03(b).

                  (d) Notwithstanding any cancellation or suspension of the
Commitment, all the provisions of this Agreement and the other Financing
Documents shall continue in full force and effect except as specifically
provided.

                  (e) The Borrower's right to request a Disbursement terminates
on the Commitment Termination Date.

                  Section 7. Representations and Warranties. The Borrower
confirms the representations and warranties contained in Section 7 of the Common
Agreement, as if made on the date of this Agreement, which representations and
warranties are incorporated herein by reference as if fully set forth herein, in
accordance with their terms.

                  Section 8. Covenants of the Borrower. The Borrower agrees

this Agreement remains unpaid, it shall observe and perform each of the
covenants set forth in Section 8 of the Common Agreement, which covenants and
agreements are incorporated by reference in this Agreement as if fully set forth
herein, in accordance with their terms.

in the circumstances described in the preceding sentence. The failure to give
any such notice or demand shall not modify or adversely affect the obligations,
duties and liabilities of the Borrower hereunder and under any of the other
Financing Documents, each of which obligations, duties and liabilities shall be
performed as though such notice or demand were given as contemplated herein and
in the other Financing Documents.

                  10.02 Waiver. No failure on the part of IDB to exercise and no
delay in exercising, and no course of dealing with respect to, any right, power
or privilege under this Agreement or the Notes shall operate as a waiver
thereof, nor shall any single or partial exercise of any right, power or
privilege under this Agreement or the Notes preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The
remedies provided herein are cumulative and not exclusive of any remedies
provided by law.

 reason, or pending the resolution, of any action or proceeding commenced by the
 Borrower relating in any way to this Agreement whether or not commenced
