partial reduction shall be in an amount at least equal to $1,000,000.

          (b) Automatic Termination of Commitment. The Commitment shall be

Note), payable on demand to the order of the Lender, dated the date of such
borrowing, and in a principal amount equal to the amount of the Loan to be made
by the Lender on such date. The rights of the Lender 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 Loan 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 Loan hereunder.

          (b) The Borrower shall re-execute the Notes as and when requested to
do so by the Lender or the Custodian for the benefit of the Lender and in any
event upon ten month intervals of the date of each disbursement; it being

Lender shall cancel, and return, or instruct the Custodian to cancel and return
to the Borrower, each such Note so paid in full.

          (d) The Lender 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 the Lender
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.

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

          Section 3. Payments of Principal and Interest.

          3.02 Interest. The Borrower hereby promises to pay to the Lender
interest on the unpaid principal amount of each Loan for the period from and

Notwithstanding the foregoing, the Borrower hereby promises to pay to the Lender
interest at the applicable Post-Default Rate on any principal of any Loan and on
any other amount payable by the Borrower hereunder or under the Notes, that
shall not be paid in full when due (whether at stated maturity, by acceleration,
by mandatory prepayment or otherwise), for the period from and including the due
date thereof to but excluding the date the same is paid in full.

          Accrued interest on each Loan shall be payable (i) on the last day of
each Interest Period therefor, and (ii) upon the payment or prepayment thereof
(but only on the principal amount so paid or prepaid), except that interest
payable at the Post-Default Rate shall be payable from time to time on demand
and, if not paid when demanded, the interest payable at the Post-Default Rate
will compound semi-annually until paid in full. Promptly after the determination
of any interest rate provided for herein or any change therein, the Lender shall
give notice thereof to the Borrower.

          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 made by the
borrower to the Lender under this Agreement and the Notes, and, except to the
extent otherwise provided therein, all payments to be made by the Borrower to
the Lender under any other Financing Document, shall be made in Dollars, in
immediately available funds, without deduction, set-off or counterclaim, not

institution as the Lender may, from time to time, notify the Borrower. Any
payments received after 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 the Lender may elect, then to interest due and
payable, then 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.

          (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.

          5.01 Changes in Market.

          (a) If in the course of establishing LIBOR for the ensuing Interest
Period, the Lender will have determined (which determination will be final,
conclusive and binding upon the Borrower) that the ability of the Lender to make
or maintain Loans in Dollars during the ensuing Interest Period has become
impractical or has been materially adversely affected because:

          (i) of any material adverse change in or the termination of the London
     Interbank Eurodollar Market and the New York Interbank Market for Dollars;

          (ii) there exist no adequate and fair means for ascertaining LIBOR
     applicable to the Loans made to the Borrower by the Lender for such
     Interest Period;

          (iii) deposits in Dollars are not available to the Lender in the
     London Interbank Eurodollar Market and the New York Interbank Market in
     sufficient amounts in the ordinary course of business for such Interest
     Period; or

          (iv) if LIBOR, for such Interest period, will not be adequately
     reflect the cost of the Lender of obtaining the deposits in Dollars
     required for such Interest Period hereunder during such Interest Period in
     the London Interbank Eurodollar Market and the New York Interbank Market;

in any such case, the Lender will promptly notify the Borrower of such
determination and will within the next succeeding sixty (60) days after such
notice, deliver to the Borrower the terms of a substitute basis for the
continuation of the indebtedness of the Borrower which is, financially, the
substantial equivalent to the Lender of the basis provided herein, including
without limitation, the continuation of such indebtedness in a freely
convertible currency other than Dollars or the funding of such indebtedness in a
financial market other than the London Interbank Eurodollar Market and the New
York Interbank Market. The terms of the substitute basis for such indebtedness
will be retroactive to and effective from the beginning of that Interest Period
for which LIBOR was being established and the provisions of this Agreement
respecting such indebtedness of the Borrower will be, ipso factor, amended to
accord with the terms of the substitute basis. The Lender will have no
obligation to make any further Loans after such event until the Lender has
determined the substitute basis.

          (b) Notwithstanding anything to the contrary contained in this
Agreement respecting prepayment, if the Lender gives the notice provided for in
this Section 5.01, the Borrower will have the right, upon written notice to
that effect (which will be irrevocable and will constitute the Borrower's
undertaking to prepay accordingly) delivered to the Lender at least thirty (30)
days prior to the next Interest Payment Date following the date of such notice
to prepay in full on such Interest Payment Date the principal indebtedness of
the Borrower together with interest accrued thereon at the substitute basis and
all other sums due hereunder to the date of such prepayment (but without the
premium contemplated in Section 2.05(b) of the Common Agreement).

          (c) In the event of such prepayment, the obligation of the Lender to
make any further Loans will, at the option of the Lender, thereupon terminate.
If the Borrower does not give such notice and prepay in accordance with the
foregoing, then the Borrower will execute and deliver to the Lender at the
Borrower's expense any and all further instruments as the Lender deems necessary
or advisable to reflect the substitute basis for the indebtedness of the
Borrower.

          5.02 Additional Costs. In the event that a law or regulation is
enacted or changed, or the interpretation or administration thereof is changed
by the administering Governmental Body, or in the event that a judgment is
rendered which:

          (a) subjects the Lender to any tax with respect to payments to be made
     by the Borrower to the Lender hereunder (except for taxes on the overall
     income of the Lender and those taxes contemplated by Section 5.05);

          (b) imposes or modifies any reserve or similar requirements against
     assets held by, or deposits in or for the account of, or loans by, an
     office of the Lender; or

          (c) imposes on the Lender any other condition with respect to this
     Agreement;

with the result that the cost to the Lender of making or maintaining Loans is
increased or the income receivable by the Lender in respect of the principal
indebtedness of the Borrower to the Lender hereunder is reduced, the Borrower
will pay to the Lender on demand that amount which will compensate the Lender
for such additional cost or reduction in income. Upon the Lender having
determined that it is entitled to additional compensation in accordance with the
provisions

                               EDC Loan Agreement
<PAGE>
                                      -8-

of this Section 5.02, the Lender will promptly notify the Borrower thereof. A
certificate of the Lender setting forth the amount of such additional
compensation and the basis therefor will be submitted by the Lender to the
Borrower and will be conclusive evidence of such amount unless shown by the
Borrower to contain clerical error. The Lender will have no obligation to make
any further Loans after such event until the Lender has received the additional
compensation.

          In the event the Lender gives the notice provided for in this Section
5.02 the Borrower will have the right, upon written notice to that effect (which
will be irrevocable and will constitute the Borrower's undertaking to prepay
accordingly) delivered to the Lender at least thirty (30) days prior to the next
Interest Payment Date, to prepay in full on such Interest Payment Date, the said
principal indebtedness of the Borrower together with accrued interest thereon,
all other sums due hereunder and the additional compensation to the date of such
prepayment (but without the premium contemplated in Section 2.05(b) of the
Common Agreement).

          In the event of such prepayment, the obligation of the Lender to make
any further Loans will, at the option of the Lender, thereupon terminate. The
obligations of the Borrower under this Section 5.02 will survive the repayment
to the Lender of the principal of and interest on the indebtedness of the
Borrower to the Lender hereunder.

          5.03 Illegality. If it will become unlawful in any relevant
jurisdiction for the Lender to continue to make or to maintain Loans or for the
Lender to make or receive any payment or to perform, exercise or to give effect
to any obligation, right or benefit under this Agreement or any related
document, the Borrower will prepay to the Lender, if requested by the Lender,
that portion of the principal amount of the Loans which the Lender notifies to
the Borrower as being affected by such change forthwith or at the end of such
period as the Lender will have permitted together with interest accrued thereon
and all other sums due hereunder to the date of such prepayment (but without the
premium contemplated in Section 2.05(b) of the Common Agreement). In the event
of any such illegality or prepayment, the obligation of the Lender to make any
further Loans will, at the option of the Lender, thereupon terminate.

          5.04 Compensation. The Borrower will indemnify and hold harmless the
Lender against any loss (including loss of profit) costs, damage, liability or
expense which the Lender will certify as sustained or incurred by the Lender as
a consequence of:

          (a) any default in repayment of principal or payment of interest or
     any other amount due hereunder;

          (b) the delay or failure of the Borrower to make payment of or in
     respect of any taxes pursuant to Section 5.05;

          (c) any payment or prepayment of principal being made on other than an
     Interest Payment Date; or

          (d) the occurrence of an Event of Default;

including, in any such case, but not limited to, any loss, cost, damage,
liability or expenses sustained or incurred by the Lender in liquidating or
re-employing deposits or funds from third

                               EDC Loan Agreement
<PAGE>
                                      -9-

parties acquired or to be acquired to make advances or maintain or continue any
amount already advanced or any part thereof. The obligations of the Borrower
under this Section 5.04 will survive the repayment to the Lender of the
principal of and interest on the indebtedness of the Borrower to the Lender
hereunder.

          5.05 Taxes.

          (a) Payments to Be Made Free and Clear of Covered Taxes. All payments
on account of the principal of and interest on the Loans, fees and all other
amounts payable hereunder by the Borrower to or for account of the Lender,
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 the Lender, 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 the
Lender.

          (b) Indemnification by the Borrower. The Borrower shall indemnify the
Lender against, and reimburse the Lender on demand for, any Covered Taxes and
any loss, liability, claim or expense, including interest, penalties and legal
fees, that the Lender 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
Loans (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.

          (d) Evidence of Payment of Covered Taxes. The Borrower shall furnish
to the Lender, 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 the Lender any other information, documents and receipts
that the Lender 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 the Lender 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 Chilean income taxes
imposed and required to be withheld and paid by the Borrower at the rate of 4%
on

                               EDC Loan Agreement

amounts payable hereunder (other than principal of the Loans) and for stamp tax
at the rate of 1.2% applicable on the principal amounts disbursed hereunder.

          Section 6. Conditions to Effectiveness of Agreement. This Agreement
shall become effective on the date on which (a) each of the conditions precedent
set forth in Section 6.01 and Section 6.02 of the Common Agreement have been
satisfied or waived by the Senior Lenders and (b) the Loans shall have been
prepaid from the proceeds of the initial disbursement of the IDB Loan in an
amount equal to the aggregate outstanding principal amount of the Loans less
$25,000,000.

          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 in this Agreement.

          Section 8. Covenants of the Borrower. The Borrower agrees that, so
long as any amount payable under 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.

          Section 9. Events of Default. Subject to the terms of the Common
Agreement, if any "Event of Default" under and as defined in the Common
Agreement shall occur and be continuing, then the Lender shall have (in addition
to any and all other available remedies at law and in equity) each of the
remedies to which it is entitled as provided in Section 9 of the Common
Agreement.

          Section 10. Miscellaneous.

          10.01 Notices. Except in the case of notices and other communications
expressly permitted to be given by telephone, any notice, claim, request,

          10.02 Waiver. No failure on the part of the Lender to exercise and
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.

          The Borrower irrevocably waives, to the fullest extent permitted by
applicable law, any claim that any action or proceeding commenced by the Lender
relating in any way to this Agreement should be dismissed or stayed by 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 earlier. To the
fullest extent permitted by applicable law, the Borrower shall take all measures
necessary for any such action or proceeding commenced by the Lender to proceed
to judgment prior to the entry of judgment in any such action or proceeding
commenced by the Borrower.

          10.03 Amendments, Etc. No provision of this Agreement may be modified
or supplemented except by an instrument in writing signed by the Borrower and

permitted assigns.

          (a) Assignments by the Borrower. The Borrower may not assign any of
its rights or obligations hereunder or under the Notes without the prior consent

be null and void.

          (b) Assignment by the Lender. The Lender may assign its Loans, its
Notes and its Commitment to any Person other than a telecommunications operator.
Upon execution and delivery by the assignee to the Borrower of an instrument in
writing pursuant to which such assignee agrees to become the "Lender" hereunder,
and so long as no Default has occurred and is continuing, upon consent thereto
by the Borrower (such consent not to be unreasonably withheld or delayed), the
assignee shall have (unless provided in such assignment with the consent of the
Borrower) the obligations, rights and benefits of the Lender hereunder in
respect of the Commitment and Loans theretofore held by the Lender, and the
Lender shall be released from the Commitment.

          (c) Participations. The Lender may sell or agree to sell to one or
more other Persons (each a "Participant") a participation in all or any part of
any Loans, or in the Commitment, provided that such Participation shall not have
any rights or obligations under this Agreement or the Notes or any other
Financing Document (the Participant's rights against the Lender in respect of
such participation to be those set forth in the agreements executed by the
Lender in favor or the Participant). All amounts payable by the Borrower to the
Lender under

<PAGE>

Section 5 in respect of Loans and the Commitment shall be determined as if the
Lender had not sold or agreed to sell any participations in such Loans and
Commitment, and as if the Lender were funding each of such Loans and Commitment
in the same way that it is funding the portion of such Loans and Commitment in
which no participations have been sold. In no event shall the Lender agree with
the Participant to take or refrain from taking any action hereunder or under any
other Financing Document except that the Lender may agree with the Participant
that it will not, without the consent of the Participant, agree to (i) increase
or extend the term of the Commitment, (ii) extend the date fixed for the payment
of principal of or interest on the related Loan or Loans or any portion of any
fee hereunder payable to the Participant, (iii) reduce the amount of any such
payment of principal or (iv) reduce the rate at which interest is payable
thereon, or any fee hereunder payable to the Participant, to a level below the
rate at which the Participant is entitled to receive such interest or fee.

     (d) Provision of Information to Assignees and Participants. The Lender may
furnish any information concerning the Borrower in the possession of the Lender
from time to time to assignees and participants (including prospective assignees
and participants) provided that such party has entered into a confidentiality
and non-disclosure agreement with the Borrower in a form acceptable to the
Borrower acting reasonably.

     10.06 Survival. The obligations of the Borrower under Sections 5.02, 5.04
and 5.05 hereof and Section 10.04 of the Common Agreement shall survive the
repayment of the Loans and the termination of the Commitment. In addition, each
representation and warranty made, or deemed to be made by a notice of any Loan,
herein or pursuant hereto shall survive the making of such representation and
warranty, and the Lender shall not be deemed to have waived, by reason of making
any Loan hereunder, any Default that may arise by reason of such representation
or warranty proving to have been false or misleading, notwithstanding that the
Lender may have had notice or knowledge or reason to believe that such
representation or warranty was false or misleading at the time such Loan was
made.

<PAGE>

                                      - 3 -

                  (c) Approvals. No Governmental Approvals are necessary for the

Direct Agreement and the other Transaction Documents to which SRT is a party,
the consummation of the transactions herein and therein contemplated or
compliance with the terms and provisions hereof and thereof will conflict with
or result in a breach of, or require any consent under, the organizational
documents of SRT, or any applicable law or regulation, or any order, writ,
injunction or decree of any court or Governmental Body, or any agreement or
instrument to which SRT or any of its Subsidiaries is a party or by which it or

under any such agreement or instrument, or (except for the Liens created
pursuant to the Security Documents) result in the creation or imposition of any
Lien upon any Property of SRT or any of its Subsidiaries pursuant to the terms
of any such agreement or instrument.

                  (e) Financial Condition; No Material Adverse Change.

                  (i) Financial Condition. SRT has heretofore furnished to the
         Senior Lenders the audited consolidated and consolidating balance
         sheets of SRT and its Subsidiaries as at December 31,1998 and the
         related audited consolidated and unaudited consolidating statements of
         income, retained earnings and cash flows of SRT and its Subsidiaries
         for the fiscal year ended on such date, with the opinion thereon (in
         the case of such consolidated balance sheet and statements) of Deloitte
         & Touche. All such financial statements are complete and correct and
         fairly present the consolidated financial condition of SRT and its
         Subsidiaries, and (in the case of such consolidating financial
         statements) the respective unconsolidated financial condition of SRT
         and its Subsidiaries, as at such dates and the consolidated and
         unconsolidated results of their operations for the fiscal year ended on
         such date, all in accordance with Canadian generally accepted
         accounting principles and practices applied on a consistent basis. None
         of SRT and its Subsidiaries has on the date hereof any material
         contingent liabilities, liabilities for taxes, unusual forward or
         long-term commitments or unrealized or anticipated losses from any
         unfavorable commitments, except as referred to or reflected or provided
         for in such balance sheets as at such date.

                  (ii) No Material Adverse Change. Since December 31, 1998,
         there has been no material adverse change in the consolidated financial
         condition, operations, business or prospects taken as a whole of SRT
         and its Subsidiaries from that set forth in the financial statements as
         at such date referred to in paragraph (i) of this Section 4(e).

                  (iii) Year 2000 Issues. SRT has undertaken a review and
         assessment of all areas within its and its Subsidiaries' business and
         operations that could be adversely affected by its or their failure to
         be Year 2000 Compliant on a timely basis and has developed and
         implemented a comprehensive detailed program for it and its
         Subsidiaries to become Year 2000 Compliant and is presently Year 2000
         Compliant and, on the basis of inquiries made, SRT reasonably believes
         that each supplier and vendor of SRT and its Subsidiaries

                                DIRECT AGREEMENT

<PAGE>

                                       - 4 -

         that is of material importance to the financial well-being of SRT and
         its Subsidiaries has achieved Year 2000 Compliance, and will remain
         Year 2000 Compliant.

                  (f) Properties.

                  (i) Property Generally. SRT owns and has on the date hereof
         good and marketable title (subject only to Liens disclosed in its most
         recent financial statements) to the Properties shown to be owned in the
         financial statements referred to in Section 4(e)(i) (other than
         Properties disposed of in the ordinary course of business).

                  (ii) Intellectual Property. Each of SRT and its Subsidiaries
         owns, or is licensed to use, all trademarks, tradenames, copyrights,
         patents and other intellectual property material to its business, and
         the use thereof by SRT and its Subsidiaries does not infringe upon the
         rights of any other Person, except for any such infringements that,
         individually or in the aggregate, could not reasonably be expected to
         result in a Borrower Material Adverse Effect or an SRT Material Adverse
         Effect.

                  (g) Litigation. There are no legal or arbitral proceedings, or
any proceedings by or before any governmental or regulatory authority or agency,
now pending or (to the knowledge of SRT) threatened against SRT or any of its
Subsidiaries that, if adversely determined, could (either individually or in the
aggregate) have a Borrower Material Adverse Effect or an SRT Material Adverse
Effect.

                  (h) Compliance with Laws and Agreements. Each of SRT and its
Subsidiaries is in compliance with all laws, regulations and orders of any
Governmental Body applicable to it or its Property and all indentures,
agreements and other instruments binding upon it or its Property, except where
the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Borrower Material Adverse Effect or an SRT Material
Adverse Effect.

                  (i) Taxes. SRT and its Subsidiaries have filed all material
tax returns that are required to be filed by them and have paid all taxes due
pursuant to such returns or pursuant to any assessment received by SRT or any of
its Subsidiaries. The charges, accruals and reserves on the books of SRT and its
Subsidiaries in respect of taxes and other governmental charges are, in the
opinion of SRT, adequate. SRT has not given or been requested to give a waiver
of the statute of limitations relating to the payment of any or other
impositions.

                  (j) True and Complete Disclosure. The information, reports,
financial statements, exhibits and schedules furnished in writing by or on
behalf of SRT to the Senior Lenders in connection with the negotiation,
preparation or delivery of this Direct Agreement and the other Transaction
Documents or included herein or therein or delivered pursuant hereto or thereto,
(a) have been prepared in good faith, based upon assumptions believed by SRT to
be reasonable and (b) when taken as a whole do not contain any untrue statement
of material fact or omit to state any material fact necessary to make the
statements herein or therein, in light of the circumstances under which they
were made, not misleading. All written information furnished after the date
hereof by SRT and its Subsidiaries to the Senior Lenders in connection with this
Direct Agreement and the other Transaction Documents and the transactions
contemplated hereby and thereby will be true, complete and accurate in every
material respect, or (in the case

                                DIRECT AGREEMENT

<PAGE>

                                      - 5 -

of projections) based on reasonable estimates, on the date as of which such
information is stated or certified. There is no fact known to SRT that could
have a Borrower Material Adverse Effect or an SRT Material Adverse Effect that
has not been disclosed herein, in the other Transaction Documents or in a
report, financial statement, exhibit, schedule, disclosure letter or other
writing furnished to the Senior Lenders for use in connection with the
transactions contemplated hereby or thereby.

                  (k) Legal Form. Each of the Transaction Documents to which SRT
is a party is in proper legal form under the laws of Canada for the enforcement
thereof against SRT under such laws, and if such Transaction Documents were
stated to be governed by such laws, they would constitute legal, valid and
binding obligations of SRT under such laws, enforceable in accordance with their
respective terms. All formalities required in Canada for the validity and
enforceability of each such Transaction Document (including, without limitation,
any necessary registration, recording or filing with any court or other
authority in Canada) have been accomplished, and no Covered Taxes are required
to be paid to Canada, or any political subdivision thereof or therein, and no
notarization is required, for the validity and enforceability thereof.

                  (1) Ranking. This Direct Agreement and the other Transaction
Documents to which SRT is a party and the obligations evidenced hereby and
thereby are and will at all times be direct and unconditional general
obligations of SRT, and rank and will at all times rank in right of payment and
otherwise at least pari passu with all other unsecured Indebtedness of SRT,
whether now existing or hereafter outstanding.

                  (m) Defaults. SRT is not in default under any material
covenant or obligation hereunder or under the Assigned Agreement and no such
default has occurred prior to the date hereof. To the best knowledge of SRT, the
Borrower is not in default under any material covenant or obligation of the
Assigned Agreement and no such default has occurred prior to the date hereof and
there exists no event or condition which would, with the giving of notice or
lapse of time or both, constitute a default under the Assigned Agreement. SRT
and the Borrower have satisfied each of the conditions precedent, if any,
contained in the Assigned Agreement.

                  5. Covenants of SRT.

                  5.1. SRT covenants and agrees with the Senior Lenders that, so
long as any Commitment or Senior Loan is outstanding under either Senior Loan
Agreement and until payment in full of all amounts payable by the Borrower
thereunder:

                  (a) Financial Statements and Other Information. SRT shall
deliver to Senior Lenders:

                  (i) a copy of all financial statements, whether annual or
         interim, of SRT and the report, if any, of SRT's auditors thereon and
         of all annual and other periodic reports of SRT furnished to its
         shareholders at the same time as they are furnished to such
         shareholders;

         documents, if any, that SRT shall have filed with the Ontario
         Securities Commission (or any securities regulatory agency substituted
         therefor);

                  (iii) from time to time such other information regarding the
         financial condition, operations, business or prospects of SRT or any of

         reasonably request.

                  (b) Notices of Material Events. SRT will furnish the following
to each Senior Lender in writing:

                  (i) promptly after SRT knows or has reason to believe that any
         Default or Event of Default has occurred, notice of such Default or
         Event of Default;

                  (ii) prompt notice of all legal or arbitral proceedings, and
         of all proceedings by or before any governmental or regulatory
         authority or agency, and of any material development in respect of such
         legal or other proceedings, affecting SRT or any of its Subsidiaries,
         except proceedings that, if adversely determined, would not (either
         individually or in the aggregate) have a Borrower Material Adverse
         Effect or an SRT Material Adverse Effect;

                  (iii) prompt notice of material changes to the Project;

                  (iv) within five days of the earlier of (A) Borrower's receipt
         thereof and (B) SUBTEL's sending thereof, notice and copies of any
         material communication with SUBTEL concerning the Concessions; and

                  (v) prompt notice of any other development that results in, or
         could reasonably be expected to result in, a Borrower Material Adverse
         Effect or an SRT Material Adverse Effect.

Each notice delivered under this Section 5.1(b) shall be accompanied by a
statement of a Financial Officer or other executive officer of SRT setting forth
the details of the event or development requiring such notice and any action
taken or proposed to be taken with respect thereto.

                  (c) Existence. Compliance, Records, Inspection. Etc. SRT will,

         franchises, including, without limitation, rights under the

                  (ii) comply with the requirements of all applicable laws,
         rules, regulations and orders of any Governmental Body if failure to
         comply with such requirements could (either individually or in the
         aggregate) have a Borrower Material Adverse Effect or an SRT Material
         Adverse Effect;

                                DIRECT AGREEMENT

<PAGE>

                                       - 7 -

                  (iii) pay and discharge all taxes, assessments and
         governmental charges or levies imposed on it or on its income or
         profits or on any of its Property prior to the date on which penalties
         attach thereto, except for any such tax, assessment, charge or levy the
         payment of which is being contested in good faith and by proper
         proceedings and against which adequate reserves are being maintained;
         and

                  (iv) permit representatives of the Senior Lenders, during
         normal business hours, to examine, copy and make extracts from its
         books and records, to inspect any of its Properties, and to discuss its
         business and affairs with its officers and the Independent Accountants,
         all to the extent reasonably requested by the Senior Lenders.

                  (d) SRT will cause the Borrower:

                  (i) to use the Borrower's bank account with Banco Santiago
         only for purposes of payroll; and

                  (ii) on or prior to the Closing Date, to enter into the
         Collection Account o Agreements in form and substance satisfactory to
         the Senior Lenders.

                  5.2. SRT covenants and agrees with the Senior Lenders that, so
long as Financial Completion has not occurred:

                  (a) Limitation on Incurrence of Additional Indebtedness SRT
will not and will not permit its Restricted Subsidiaries to, directly or
indirectly, incur additional Indebtedness unless, after giving effect to the
incurrence of such Indebtedness and the receipt and application of the proceeds
thereof:

                  (i) Consolidated Indebtedness to Consolidated EBITDA for the
         period comprised of the four consecutive completed fiscal quarters
         ended immediately prior to the incurrence of such Indebtedness, would
         be less than 4:1; and

                  (ii) Consolidated Indebtedness as a percentage of Consolidated

                  6. Consent and Agreement. Notwithstanding anything to the
contrary in the Assigned Agreement, SRT hereby acknowledges and agrees that:

                  (a) After any Senior Lender gives written notice to SRT that
an Event of Default has occurred, the Senior Lenders and any assignee thereof
shall be entitled to exercise any and all rights of the Borrower under the
Assigned Agreement in accordance with its respective terms and SRT shall comply
in all respects with such exercise.

                  (b) SRT will not, without the prior written consent of the
Senior Lenders, take any action to (i) cancel or terminate, or suspend
performance under, the Assigned Agreement unless such cancellation, termination
or suspension is expressly provided for in the Assigned Agreement, SRT shall

such notice and the Senior Lenders have consented to such cancellation,
termination or suspension, (ii) consent to or accept any cancellation,
termination or suspension of the Assigned Agreement, (iii) amend, supplement or
otherwise modify the Assigned Agreement (as in effect on the date hereof) or
(iv) sell, assign or otherwise dispose of (by operation of law or otherwise) any
part of its interest in the Assigned Agreement.

                  (c) SRT shall deliver to the Senior Lenders at the address set

liability for all of the Borrower's obligations under the Assigned Agreement
arising after the date of such succession. Except as otherwise set forth in the
immediately preceding sentence, the Senior Lenders shall not have any duties or
obligations whatsoever to SRT under the Assigned Agreement or with respect to
any of the transactions contemplated hereby or thereby.

                  (e) Upon SRT's receipt of a notice from the Senior Lenders
stating that it intends to take one or more actions, or exercise one or more
remedies after the occurrence and during the continuance of an Event of Default,
the Senior Lenders may assign their rights and interests and the rights and
interests of the Borrower under the Assigned Agreement to any purchaser or
transferee of the Project, if such purchaser or transferee has agreed to assume
all of the obligations of the Borrower under the Assigned Agreement. Upon such
assignment and assumption, the Senior Lenders shall be relieved of all
obligations under the Assigned Agreement arising after such assignment and
assumption.

by a trustee or debtor-in-possession in any bankruptcy or insolvency proceeding
involving the Borrower or (ii) the Assigned Agreement is terminated as a result
of any bankruptcy or insolvency proceeding involving the Borrower and, if within
90 days after such rejection or termination, the Senior Lenders or their
designee(s) shall so request and shall certify in writing to SRT that they or it
intends to perform the obligations of the Borrower as and to the extent required
under the Assigned Agreement, SRT will execute and deliver to the Senior Lenders
or such designee(s) a new Assigned Agreement which shall be for the balance of
the remaining term under the original Assigned Agreement before giving effect to
such rejection or termination and shall contain the same conditions, agreements,
terms, provisions and limitations as the original Assigned Agreement (except for
any requirements which have been fulfilled by the Borrower and SRT prior to such
rejection or termination). References in this Direct Agreement to the "Assigned
Agreement" shall be deemed also to refer to the new Assigned Agreement.

                  (g) In the event that the Senior Lenders or their designee(s),
or any purchaser, transferee, grantee or assignee of the interests of the Senior
Lenders or their designee(s) in the Project shall assume or be liable under the
Assigned Agreement (as contemplated in subsection (d), (e) or (f) above or
otherwise), liability in respect of any and all obligations of any such party
under the Assigned Agreement shall be limited solely to such party's interest in
the Project (and no officer, director, employee, shareholder or agent thereof
shall have any liability with respect thereto).

                  7. Special Agreements. Notwithstanding any provisions of the
Assigned Agreement to the contrary, SRT agrees that:

                  (a) the Senior Lenders shall have the right at any time, upon
         reasonable notice to SRT, to review and audit the relevant internal
         records of SRT which support or verify the invoices and charges levied
         against the Borrower with respect to services provided under the
         Assigned Agreement;

                  (b) except with the consent of the Senior Lenders, and
         notwithstanding the amount of invoices and charges levied against the
         Borrower with respect to services provided under the Assigned
         Agreement, SRT shall not collect from or be paid by the Borrower any
         amount in excess of 10% of the Canadian scope of the maintenance
         replacement costs set out in the Agreed Financial Model in respect of
         such services;

                  (c) after the occurrence and during the continuation of an
         Event of Default, except with the consent of the Senior Lenders, the
         Borrower shall not pay, and SRT shall not collect, any amounts due or
         falling due under the Assigned Agreement and any such amounts that
         accrue during such time shall only be paid (A) after the Event of
         Default is cured or ceases to exist; and (B) payment of any such amount
         will not result in the occurrence of an Event of Default; and

                  (d) the occurrence of an Event of Default shall in no way
         relieve or excuse SRT from its obligations under the Assigned
         Agreement.

                  8. Arrangements Regarding Payments. To the extent that any
payments are made by SRT to the Borrower after the occurrence and during the
continuation of an Event of Default, all such payments to be made by SRT to the
Borrower under the Assigned Agreement shall be made in lawful money of the
United States of America, directly to the Senior Lenders pro rata to the
aggregate outstanding Obligations then owing to the Senior Lenders. If such
payments are made to EDC, such payment should be made for deposit at Citibank

institution as EDC may, from time to time, notify SRT) to be held as security
for payment of all obligations owing to EDC by the Borrower, and shall be
accompanied by a notice from SRT stating that such payments are made under the
Assigned Agreement. If such payments are made to IDB, such payments shall be
made for deposit at Bankers Trust Company, New York, ABA number 021001033,
Attention: MT-Foreign Section, for credit to the account of IDB-PRI account
number 04246884 (or such other account or financial institution at IDB may from
time to time, notify SRT) to be held as security for payment of all obligations
owing to IDB by the Borrower, and shall be accompanied by a notice from SRT
stating that such payments are made under the Assigned Agreement.

                  9. Miscellaneous.

                  (a) No failure on the part of the Senior Lenders or any of
their agents to exercise and no delay in exercising, and no course of dealing
with respect to, any right, power or privilege hereunder shall operate as a
waiver thereof, and no single or partial exercise of any right, power or
privilege hereunder shall 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.

                  (b) This Direct Agreement shall terminate on the date on which

invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.
If any provision of this Direct Agreement shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and enforceability of

                  (h) THIS DIRECT AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                  (i) SRT hereby agrees that any suit, action or proceeding with
respect to this Direct Agreement, any other Transaction Document or any judgment
entered by any court in respect thereof may be brought by any Senior Lender in
the courts of the Province of Ontario, Canada or 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 SRT hereby
irrevocably submits to the jurisdiction of such courts for the purpose of any
such suit, action, proceeding or judgment. SRT 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.

                  (j) SRT hereby agrees that service of all writs, process and
summonses in any such suit, action or proceeding with respect to this Direct
Agreement, any other Transaction Document or any judgment entered by any court
in respect thereof brought in (i) the Province of Ontario may be made upon SRT,
presently located at the address noted in Section 9(d) (the "Canadian Process
Agent") or (ii) the State of New York may be made upon CT Corporation, presently
located at 111 Eighth Avenue, 13th Floor, New York, New York 10011, USA, (the
"US Process Agent" and, together with the Canadian Process Agent, the "Process
Agents"), and hereby confirms and agrees that the Process Agents have 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 Agents to give
any notice of any such service of process to SRT shall not impair or affect the
validity of such service or of any judgment based thereon. SRT hereby further
irrevocably consents to the service of process in any suit, action or proceeding
in said courts by the mailing thereof by the Senior Lenders by registered or
certified mail, postage prepaid, at its address set forth beneath its signature
hereto.

                  (k) Nothing herein shall in any way be deemed to limit the
ability of the Senior Lenders to serve any such writs, process or summonses in
any other manner permitted by applicable law or to obtain jurisdiction over SRT
in such other jurisdictions, and in such manner, as may be permitted by
applicable law.

                  (1) SRT hereby irrevocably waives 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 Direct Agreement or any other
Transaction Document brought in the courts of the Province of Ontario, Canada or
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

                  (m) This Direct Agreement shall come into full force and
effect, and amend and restate the Direct Agreement dated as of April 13. 1999
among SRT, the Borrower and EDC as

                                DIRECT AGREEMENT

<PAGE>

                                     - 13 -

of the date on which the EDC Loan Agreement becomes effective in accordance with
Section 6 thereof.

                  (n) THE BORROWER AND SRT HEREBY IRREVOCABLY WAIVE, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY
IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS DIRECT AGREEMENT OR
THE TRANSACTIONS CONTEMPLATED HEREBY.

                  (o) Any specification of Dollars and payment in New York City
contained in this Direct Agreement is of the essence, and the obligations of SRT
under this Direct Agreement to make payment to (or for account of) the Senior
Lenders 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 the Senior Lenders in New York City of the
full amount of Dollars payable to the Senior Lenders under this Direct
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
9(o) called the "Judgment Currency"), the rate of exchange that shall be applied
shall be that at which in accordance with normal banking procedures the Senior
Lenders could purchase such Dollars with the Judgment Currency on the Business
Day next preceding the day on which such judgment is rendered. The obligation of
SRT in respect of any such sum due from it to the Senior Lenders hereunder or
under any other Financing Document 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 the Senior Lenders of any sum
adjudged to be due hereunder in the Judgment Currency the Senior Lenders may in
