<PAGE>
              (D)  the issuance of CP Notes is for the time being prohibited by

              (E)  the Commitments have been reduced, effective on the maturity

         issue or deliver any CP Note; provided, however, that the Depositary
         may be required to deliver CP Notes in respect of which a final
         agreement for sale was concluded by a Dealer prior to receipt by such

         telephone if promptly confirmed by facsimile or other written
         transmission), with a copy to the Issuing Bank, the Administrative
         Agent and each Dealer, of such revision or revocation, and any such
         instruction given by the Issuing Bank or the Administrative Agent (or
         the Borrower) shall be revised or revoked by it if the condition or
         conditions giving rise to such instruction shall have been remedied
         or cured to the reasonable satisfaction of the Issuing Bank, the
         Administrative Agent and the Majority Banks; provided, however, that
         the Issuing Bank or the Administrative Agent, acting without the
         consent of the Majority Banks, may revise or revoke any instructions
         given by it not to issue or deliver CP Notes due to clause (b)(i)(C)
         or (b)(i)(D) of this Section 2.2 so long as

              (iv)  Notwithstanding anything in this Agreement to the contrary,
         no notice pursuant to this Section 2.2(b) shall be required to be sent
         to the Borrower if an Event of Default specified in Section 9.1(f)
         shall have occurred.

Bank shall have the right to waive the Settlement Limit with subsequent notice
to the Borrower and the Dealers, but without the consent of any party to the
Principal Documents.

         against presentation of a sight draft or certificate which does not
         comply with the terms of the Letter of Credit;

              (iv)  any amendment to, waiver of, or consent to the departure
         from, the terms of, this Agreement or any of the other Principal
         Documents;

              (v)   the lack of validity or enforceability of any CP Note or any
         agreement or document related thereto; or

              (vi)  any other circumstance or happening whatsoever, whether or
         not similar to any of the foregoing;

         provided, however, that the provisions of clauses (i) through (vi)
inclusive above shall not limit any right or claim the Borrower may have
against the Issuing Bank to the extent, but only to the extent, of any direct,
as opposed to consequential or special, damages suffered by

                                       27

the Borrower which the Borrower proves were caused by the Issuing Bank's gross
negligence or willful misconduct, it being understood that the existence of any
such right or claim shall not in any way affect the obligation of the Borrower
to reimburse the Issuing Bank for all LOC Advances.

         SECTION 2.4.      Commercial Paper Account.

         (a)  (i)    The Depositary, as agent for the Issuing Bank, has
established at its Corporate Trust offices in New York, New York a special
purpose non-interest bearing account (for the benefit of the Issuing Bank)
identified as Standard Chartered Bank (TFM, S.A. de C.V.  CP Program)
Commercial Paper Account (the "Commercial Paper Account"), over which the
Issuing Bank has exclusive control and the sole right of withdrawal.  The
Borrower hereby acknowledges that except for the Issuing Bank and the
Depositary, as agent for the Issuing Bank and as provided in Section 2.4(c), no
Person (including the Borrower) shall have any legal or beneficial interest in
the Commercial Paper Account.

              (ii)   All proceeds from the sale of CP Notes will initially be
         paid into the Commercial Paper Account.  Pursuant to Section 1(b) of
         the Depositary Agreement, the Issuing Bank has issued standing
         instructions to the Depositary in writing, in the form of Exhibit E
         to the Depositary Agreement, that, subject to the conditions that
         there shall not have occurred and be continuing any Default or Event
         of Default, and that the funds in the Commercial Paper Account are
         not subject to any investigation, writ, order, judgment, warrant of
         attachment, execution or similar process or to any stay or other
         similar legal restraint and that, after giving effect to any transfer
         from the Commercial Paper Account in accordance with the terms
         hereof, the Outstanding Extensions of Credit would not exceed the
         Commitments then in effect, the Issuing Bank shall be deemed to have
         authorized and directed the Depositary to transfer to other accounts
         or Persons specified to the Depositary in writing (or by telephone or
         facsimile transmission, and in the case of telephonic notice,
         promptly confirmed in writing) by the Borrower (with a copy of all
         written communications to be sent contemporaneously to the Issuing
         Bank), funds on deposit in the Commercial Paper Account in excess of
         the aggregate amount payable (including interest, to the extent
         provided for herein) or that would be payable on the day of such
         transfer by the Borrower in respect of any LOC Advances relating to
         matured CP Notes and any Loans outstanding which are subject to
         mandatory prepayment pursuant to Section 3.5(b); provided that the
         Issuing Bank shall not be liable to any Person for any such transfer
         of funds made pursuant to the Borrower's written request.

              (iii)  The Issuing Bank may, and at the direction of the
         Administrative Agent shall, in each case, without demand or prior
         notice of any kind (but with concurrent notice sent to the Borrower,
         although the failure to deliver such notice shall not result in any
         liability to the Administrative Agent, the Issuing Bank or the
         Depositary), at any time and from time to time, cause the Depositary
         to debit the Commercial Paper Account first for the amount of any
         unreimbursed LOC Advances incurred by the Borrower and interest
         thereon, second any Loans

                                       28
<PAGE>
         outstanding which are subject to mandatory prepayment pursuant to
         Section 3.5(b) and interest thereon and third for any amount in
         respect of costs due and unpaid hereunder by the Borrower (if there
         be sufficient funds therein) and to wire transfer such debit amount
         to the Issuing Bank or the Administrative Agent, as the Issuing Bank
         may direct.  In addition, upon the occurrence of an Event of Default,
         the Issuing Bank may, and at the direction of the Administrative
         Agent shall, in each case, without demand or prior notice of any kind
         (but with concurrent notice sent to the Borrower, although the
         failure to deliver such notice shall not result in any liability to
         the Administrative Agent, the Issuing Bank or the Depositary), cause
         the Depositary to debit the Commercial Paper Account for any amount
         in respect of Fees, expenses or any other Obligations and to wire
         transfer such debit amount to the Issuing Bank or the Administrative
         Agent, as the Issuing Bank may direct.

         (b)     Subject to the provisions of Section 9.2, (i) the Issuing Bank
will not accept any payment by the Borrower, through the Depositary, for
reimbursement of the Obligations (whether with the proceeds of Loans or
otherwise) prior to 11:30 a.m., New York City time, on the day any payment is
made in respect of a drawing under the Letter of Credit and (ii) the Issuing
Bank will not request the Depositary to debit the Commercial Paper Account for
any payment in respect of the Obligations prior to 1:30 p.m., New York City
time, on the date of any drawing under the Letter of Credit, and in the case of
each of clauses (i) and (ii) above, in no event prior to the time the Issuing
Bank honors such drawing.

         (c)     In order to secure and to provide for the repayment of the
Obligations, and until the Obligations shall be paid in full and the
Commitments have been terminated, the Borrower hereby irrevocably sells,
assigns, pledges, grants and conveys to the Issuing Bank, as agent for the
ratable benefit of the Banks and the Issuing Bank, all of its right, title and
interest in and to: (i) the net proceeds from the sale of CP Notes, (ii) the
Commercial Paper Account and (iii) all the funds at any time and from time to
time on deposit in, or otherwise to the credit of, and all proceeds of, the
Commercial Paper Account (all such proceeds, accounts and funds being herein
called the "Deposited Funds") and all claims of the Borrower in and to the
Deposited Funds.

         (d)     The Borrower, the Issuing Bank, the Banks and the
Administrative Agent acknowledge that, for so long as the Letter of Credit is
in effect or any amounts payable hereunder or to the holders of the CP Notes
remain unpaid, the Depositary, as agent for the Issuing Bank, the
Administrative Agent and the Banks, shall be a pledgee in possession of the
Deposited Funds and the Issuing Bank shall have the sole and exclusive right to
withdraw or order a transfer of Deposited Funds from the Commercial Paper
Account.  The Borrower hereby appoints the Issuing Bank the true and lawful
attorney of the Borrower, with full power of substitution, for the purpose of
directing the Depositary to make any such withdrawal or order any such transfer
of Deposited Funds from the Commercial Paper Account pursuant to this Section
2.4 and Section 1(b) of the Depositary Agreement, which appointment is coupled
with an interest and is irrevocable.

         (e)     Upon the occurrence and during the continuance of any Event of
Default, the Issuing Bank will, at any time and from time to time, appropriate
and apply, or cause the

                                       29
<PAGE>
Depositary to apply, the Deposited Funds, whether then held or thereafter
acquired, to the payment or prepayment in full of all outstanding Obligations,
whether or not then due, but subject to Section 2.4(b) and to the requirement
that all payments under the Letter of Credit shall be made by the Issuing Bank
from its own funds other than Deposited Funds.  The Issuing Bank shall, in
addition to the rights and powers provided for herein, be entitled to exercise
from time to time any rights and remedies available to it under applicable law
as a secured party in respect of the Deposited Funds.  The Issuing Bank shall
not be liable to any Person for any incorrect or improper payment made pursuant
to this Section 2.4 in the absence of gross negligence or willful misconduct.

         (f)     The Borrower agrees that it will maintain in the Commercial
Paper Account on each maturity date of the CP Notes in immediately available
funds an amount equal to the Face Amount of all CP Notes scheduled to mature on
such day; provided, however, that in determining the amount of funds in the
Commercial Paper Account for purposes of this paragraph (f), there shall be
included funds payable on or before 5:00 p.m. (New York City time) on account
of the purchase price of CP Notes duly issued and delivered on such day in
accordance with the provisions of this Agreement and the Depositary Agreement
and to be deposited in the Commercial Paper Account.

         SECTION 2.5.      Letter of Credit Account.

         (a)     The Depositary has established at its Corporate Trust offices
in New York, New York, a special purpose non-interest bearing account
identified as the TFM, S.A. de C.V.  Letter of Credit Account (the "Letter of
Credit Account").  The Letter of Credit Account is in the name of the
Depositary, as paying agent for the CP Notes, and under the exclusive control
of the Depositary as such paying agent.  Except for the holders of the CP Notes
and the Depositary, as such paying agent, no Person shall have any legal or
beneficial interest in the Letter of Credit Account.  The funds in the Letter
of Credit Account shall be subject to withdrawal solely by the Depositary, as
paying agent for the CP Notes, and solely for the purpose of paying matured CP
Notes in respect of which the Depositary has made a drawing under the Letter of
Credit.  All payments by the Issuing Bank under the Letter of Credit with
respect to CP Notes shall be made directly to the Letter of Credit Account and
no funds in the Letter of Credit Account shall be commingled with monies from
any other source.

         (b)     The Depositary Agreement provides that prior to 4:00 p.m., New
York City time, on the Business Day immediately preceding the day on which CP
Notes mature, the Depositary shall make drawings under the Letter of Credit in
an aggregate amount equal to the aggregate Face Amount of such maturing CP
Notes, as the case may be, and prior to 1:00 p.m.  New York City time, on the
maturity date of such CP Notes, the Issuing Bank will honor such drawings by
making a wire transfer to, or causing to be deposited in, the Letter of Credit
Account, as applicable, an amount in Dollars in immediately available funds
equal to the amount so drawn.  The Depositary will record the date and time of
receipt of each wire transfer sent by the Issuing Bank to the Letter of Credit
Account and keep accurate records of each disbursement therefrom.  The Issuing
Bank agrees that all LOC Advances shall be paid out of the general funds of the
Issuing Bank and that no payments under the Letter of Credit shall in any way
be contingent upon or drawn from amounts on deposit in the Commercial Paper
Account or amounts on deposit in any account maintained by the Borrower with
the Issuing Bank or the

                                       30
<PAGE>
Administrative Agent.  The Issuing Bank further agrees that no CP Notes shall
be paid by the Issuing Bank except in the manner provided in the Depositary
Agreement.

         SECTION 2.6.      Change in Law Applicable to the Letter of Credit.

         In the event that any restrictions are imposed upon the Issuing Bank
or the Borrower by any law or regulation, existing or future, of any
Governmental Authority, including any legal lending limits imposed by law or
regulations of the United States or any State thereof, which in the opinion of
counsel to the Issuing Bank, promptly confirmed in writing with a copy to the
Borrower, would prohibit the Issuing Bank from issuing or maintaining the
Letter of Credit or would prohibit the issuance or the sale by the Borrower of
CP Notes supported by the Letter of Credit, the Issuing Bank shall promptly
give notice thereof in accordance with Section 2.2 to the Borrower, the
Administrative Agent (which in turn will give notice to the Banks), the Dealers
and the Depositary and, upon the giving of such notice, the obligation of the
Issuing Bank to permit any further issuance of CP Notes supported by the Letter
of Credit shall terminate; provided, that such event shall be treated for all
purposes hereunder, subject to all applicable restrictions and limitations, as
a Force Majeure Disruption Event.

         SECTION 2.7.      Effect on the Letter of Credit. Notwithstanding
anything herein to the contrary, no suspension, termination or reduction of the
Commitments or delivery of notice to cease issuing CP Notes pursuant to the
terms of this Agreement shall affect, terminate or reduce (a) the liability of
the Issuing Bank under the Letter of Credit with respect to any CP Notes
validly issued in accordance with the terms and provisions of the Depositary
Agreement or (b) the liability of the Borrower with respect to any LOC Advance
relating to the Letter of Credit or any Loan hereunder or (c) the obligation of
any Bank to reimburse the Issuing Bank for such Bank's Participation Fraction
of any LOC Advance in accordance with the terms of this Agreement.

         SECTION 2.8.      Participation and Funding Commitments.

         (a)     (i)   The Issuing Bank hereby sells and transfers to each Bank
and each Bank hereby unconditionally and irrevocably, severally and for itself
only, purchases and acquires an undivided participation interest, to the extent
of such Bank's Participation Fraction in the Commitments, in the LOC Advances,
all interest thereon and all other rights and obligations of the Issuing Bank
under, and in connection with, the Letter of Credit and the Letter of Credit
Facility with respect thereto.

                 (ii)  The several obligations and liabilities of the Banks to
         the Issuing Bank hereunder shall be absolute, irrevocable and
         unconditional under any and all circumstances whatsoever and shall
         not be affected by any circumstance, including (A) any set-off,
         counterclaim, recoupment, defense, or other right which such Bank or
         any other Person may have against the Administrative Agent, the
         Issuing Bank or any other Person for any reason whatsoever; (B) the
         occurrence or continuance of a Default or Event of Default or the
         termination of the Commitments or the Letter of Credit; (C) any
         adverse change in the condition (financial or otherwise) or prospects
         of the Borrower; (D) any breach of any of the Principal Documents by
         any party thereto; (E) the fact that any condition

                                       31
<PAGE>
         precedent to the issuance of CP Notes or the making of any
         payment under the Letter of Credit was not in fact met; (F) any
         violation or asserted violation of law by any Bank or any affiliate
         thereof; or (G) any other circumstance, happening or event
         whatsoever, whether or not similar to any of the foregoing. Each
         Bank agrees to pay and discharge when due its Participation Fraction
         in the Issuing Bank's liability under the Letter of Credit by paying
         to the Issuing Bank in accordance with Section 2.8(b) its
         Participation Fraction of each amount paid by the Issuing Bank under
         the Letter of Credit; provided, however, that the provisions of
         clauses (A) through (G) inclusive above shall not limit any right or
         claim any Bank may have against the Issuing Bank to the extent, but
         only to the extent, of any direct, as opposed to consequential or
         special, damages suffered by such Bank which such Bank proves were
         caused by the Issuing Bank's gross negligence or willful misconduct,
         it being understood that the existence of any such right or claim
         shall not in any way affect the obligation of such Bank to reimburse
         the Issuing Bank for all LOC Advances.

         (b)     (i)    As promptly as practicable upon becoming aware that it
has not been or will not be reimbursed for any LOC Advance before 5:00 p.m.,
New York City time, on the Disbursement Date for such LOC Advance or that such
LOC Advance will convert to Base Rate Loans pursuant to Section 3.1, the
Issuing Bank will notify the Administrative Agent of the amount of and
Disbursement Date for such LOC Advance.  Such notification may be given
telephonically, but shall in all events be confirmed promptly by facsimile or
other written notice in substantially the form of Exhibit D.

                 (ii)   Not later than 2:00 p.m., New York City time, on the
         Business Day on which such notice from the Issuing Bank, pursuant to
         Section 2.8(b)(i), is received (if such notice is received at or
         prior to 1:00 p.m., New York City time, on such day) or as promptly
         as practicable and not later than 10:00 a.m., New York City time on
         the next succeeding Business Day (if such notice is received after
         such time), the Administrative Agent shall notify each Bank by
         facsimile transmission or telephone (any such facsimile transmission
         or telephone conversation to be promptly confirmed by an original in
         writing) of its pro rata share of such LOC Advance or the amount of
         its Loan into which such share is converted, based on its
         Participation Fraction, and forthwith upon receipt of such notice,
         each Bank shall make available its pro rata share of such LOC Advance
         or the amount of its Loan into which such share is converted to the
         Administrative Agent as set forth on Schedule 1.1(b) in immediately
         available funds, not earlier than 1:30 p.m., New York City time, on
         such Disbursement Date and not later than (A) 4:00 p.m., New York
         City time, on the day such notice from the Administrative Agent is
         received (where the relevant notice is received at or prior to 2:00
         p.m., New York City time, on any Business Day), or (B) 12:00 noon,
         New York City time, on the next succeeding Business Day (where the
         relevant notice is received after 2:00 p.m., New York City time, on
         any day).

                 (iii)  Each Bank shall indemnify and hold harmless the Issuing
         Bank from and against any and all losses, liabilities (including
         liabilities for penalties), actions, suits, judgments, demands, costs
         and expenses (including reasonable fees

                                       32
<PAGE>
         and disbursements of counsel including the allocated cost of internal
         counsel) resulting from any failure on the part of such Bank to
         provide, or from any delay in providing, the Administrative Agent
         with such Bank's pro rata share of the amount of any LOC Advance or
         the amount of its Loan in accordance with the provisions of Section
         2.8(b)(ii) or Section 3.1(a), as the case may be, but (A) no Bank
         shall be so liable for any such failure on the part of any other Bank
         and (B) no Canadian Bank shall be liable for any delay in providing
         the Administrative Agent with such Canadian Bank's pro rata share of
         the amount of any LOC Advance or Loan so long as such Canadian Bank
         provides the Administrative Agent with such Canadian Bank's pro rata
         share within three Business Days (it being understood that such three
         Business Day exception shall only apply to Canadian Banks which
         cannot provide their pro rata share earlier due to it not being a
         Canadian Business Day); provided further, that in any event each
         Canadian Bank shall reimburse the Issuing Bank or the Borrower, as
         the case may be, at the Federal Funds Effective Rate for any direct
         costs to the Issuing Bank or the Borrower, as applicable, arising
         from the Canadian Bank's delay in payment..  If a Bank does not make
         available to the Administrative Agent when due such Bank's pro rata
         share of any LOC Advance or the amount of any such Loan, such Bank
         shall be required to pay interest to the Issuing Bank on its pro rata
         share of such LOC Advance or such Loan at the Federal Funds Effective
         Rate from the date such Bank's payment is due until the date it is
         received by the Issuing Bank.  If the Issuing Bank receives a Bank's
         pro rata share of any LOC Advance on the Disbursement Date therefor,
         or if the Issuing Bank receives interest on any late payment from
         such Bank in accordance with the provisions of the preceding
         sentence, such Bank shall receive interest on its pro rata share of
         such LOC Advance in accordance with paragraph (c) of this Section 2.8
         from such Disbursement Date.  If the Issuing Bank does not receive a
         Bank's pro rata share of any LOC Advance on the Disbursement Date
         therefor and does not receive interest on any such late payment from
         such Bank in accordance with the provisions of this paragraph, such
         Bank shall receive interest on its pro rata share of such LOC Advance
         in accordance with paragraph (d) of this Section 2.8 from the date on
         which such Bank's payment is received by the Issuing Bank.

         (c)     (i)   Whenever the Issuing Bank shall receive any payment in
the form of reimbursement from the Borrower of any LOC Advance or any payment
of interest on any such unreimbursed LOC Advance, which payment relates to an
amount for which the Issuing Bank has received reimbursement from the Banks
pursuant to this Agreement, the Issuing Bank will promptly pay to each Bank, in
immediately available funds, such Bank's pro rata share, computed in accordance
with its Participation Fraction, of such payment (x) before the close of
business on the day such payment is received, if such payment is received at or
prior to 12:00 noon, New York City time, on such day or (y) before 2:00 p.m.,
New York City time, on the next succeeding Business Day if such payment is
received after 12:00 noon, New York City time, on such day; provided, however,
that such Bank shall only be entitled to share in payments relating to interest
in accordance with the provisions of paragraph (b) of this Section 2.8.  Any
amounts received by the Issuing Bank that are due and owing to the Banks and
remain unpaid to the Banks after the date on which the Issuing Bank receives
such amounts shall bear interest, payable by the Issuing Bank, at the Federal
Funds Effective Rate from the day such amounts are

                                       33
<PAGE>
received until the day such payment is made. Each Bank shall have a direct
claim against the Borrower for the principal of and interest on each portion of
a LOC Advance advanced by it to the Issuing Bank to the extent that the
Borrower does not reimburse the Issuing Bank for such LOC Advances.

                 (ii)  If on any date on which LOC Advances are outstanding, the
         Issuing Bank receives payment from the Borrower in an amount less
         than the aggregate amount of such LOC Advances, together with accrued
         and unpaid interest thereon, such payment shall be allocated to the
         Banks pro rata in proportion to the aggregate amount of LOC Advances
         then outstanding, respectively, to be distributed to the Banks, as
         the case may be, as provided in clause (i) of this paragraph (c).

         (d)     If a Bank fails to make any payments under this Section 2.8,
and if any such payments are not made prior to the expiration of five Business
Days following notice of such nonpayment given by the Issuing Bank to such
Bank, then (i) the Issuing Bank (with the prior consent, such consent not to be
unreasonably withheld, of the Borrower) may cause such Bank to transfer to it
or to a third party or (ii) the Borrower (with the prior consent, such consent
not to be unreasonably withheld, of the Issuing Bank) may cause such bank to
transfer to a third party (which in any case must be a bank or financial
institution organized and licensed under the laws of Mexico or a commercial
bank registered with Hacienda) in exchange for the sum or sums due hereunder
from such Bank, such Bank's participation interest hereunder, and all other
rights of such Bank under this Agreement, without, however, relieving such Bank
from any liability for damages, costs and expenses suffered by the Issuing Bank
as a result of such failure.  The purchaser of any such interest (including the
Issuing Bank) shall be deemed to have acquired an interest senior to the
interest of such Bank and, accordingly, (i) such purchaser shall be entitled to
receive all subsequent payments which the Issuing Bank would otherwise have
made hereunder to such Bank, (ii) such purchaser (if not already a party to
this Agreement) shall immediately become a party to this Agreement without the
need for any further amendment hereto, (iii) the Borrower shall promptly
execute and deliver to such purchaser one or more Notes pursuant to Section 3.2
below, and (iv) such Bank shall thereupon cease to be a Bank party to this
Agreement and shall cease to have any further rights in respect hereof or in
respect of such Bank's Notes, which shall be deemed canceled, except that such
Bank shall continue to be entitled to be reimbursed for all amounts previously
advanced by it not theretofore reimbursed and all unpaid Loans theretofore made
by it and not repaid and to be paid any interest thereon to which such Bank is
entitled in accordance with this Agreement; provided, however, that such Bank's
entitlement to be so reimbursed and paid in full shall be subordinate and
junior in all respects to the rights of all other Banks, including the
purchaser, to be paid all amounts due and owing to them hereunder.  Following
such reimbursements, such Bank shall forthwith return its Notes to the Borrower
marked "canceled".

         SECTION 2.9.      Market Disruption Events.

         (a)     If, based upon information provided by the Dealers, the
Borrower shall determine on any Business Day that a CP Disruption Event shall
have occurred, the Borrower shall immediately cease issuing CP Notes and
written notice of such determination (pursuant to a Notice of CP Disruption
Event in substantially the form of Exhibit H) shall be given to the

Issuing Bank, the Joint Lead Arrangers and the Administrative Agent by the
Borrower no later than 11:00 a.m., New York City time, on such Business Day.
If, in accordance with the preceding sentence, the Borrower ceases to issue CP
Notes, the Borrower shall also promptly give notice to the Depositary pursuant
to the Depositary Agreement not to issue and deliver any CP Notes.  The
Administrative Agent shall give prompt written notice of such determination to
the Banks.

         (b)     If the Issuing Bank shall determine on any Business Day that a
Force Majeure Disruption Event shall have occurred, then the Issuing Bank may,
but shall not be obligated to, give notice to the Depositary pursuant to the
Depositary Agreement, in the form provided in Exhibit L hereto, not to issue
and deliver any CP Notes.  The Issuing Bank shall give prompt written notice of
such determination to the Borrower, the Joint Lead Arrangers, the
Administrative Agent and the Dealers.  The Administrative Agent shall give
prompt written notice of such determination to the Banks.  In the case of a
Force Majeure Disruption Event, the Borrower may elect to substitute the
Issuing Bank, with the consent of the Majority Banks (which consent shall not
be unreasonably withheld); provided, (i) no CP Notes are outstanding, (ii) the
Issuing Bank shall have received for its own account payment in full for all
amounts owing to it under the Principal Documents (whether due and payable at
such time or otherwise), including, without limitation, all fees and
reimbursement obligations, (iii) each of Moody's and S&P shall have consented
to the substitution of the Issuing Bank and shall have confirmed the rating of
the Letter of Credit with the substitution of the Issuing Bank, (iv) if the
Force Majeure Disruption Event was precipitated by a downgrade in the rating of
the Issuing Bank by Moody's or S&P, then the new issuing bank shall have a
higher rating by Moody's and/or S&P, as applicable, than the Issuing Bank, (v)
the Borrower shall deliver any other document reasonably requested by the
Administrative Agent or either Rating Agency, including customary opinions of
counsel.  Once each of the conditions described in the immediately preceding
sentence have been met, the Issuing Bank promptly shall assign all of its
rights and interest under this Agreement and all other documents executed in
connection herewith to the new issuing bank.

         (c)     In the event the issuance of CP Notes by the Borrower is
suspended as a result of this Section 2.9, the Borrower may incur Loans in
accordance with the terms and provisions of Section 3.1.

         (d)     If, based upon information provided by the Dealers, the
Borrower shall determine on any Business Day that a CP Disruption Event shall
have ceased to exist, then written notice of such determination (pursuant to a
Notice of CP Disruption Event, in substantially the form of Exhibit H) shall be
given to the Issuing Bank, the Joint Lead Arrangers, the Administrative Agent
and the Depositary by the Borrower as soon as possible after any such
information has been given by the Dealers to the Borrower, whereupon the
Borrower may revoke forthwith any instructions to the Depositary not to issue
and deliver CP Notes and the Borrower may, subject to concurrent or prior
prepayment of all Loans in accordance with Section 3.5(b), recommence issuing
CP Notes.  The Administrative Agent shall give prompt written notice to the
Banks upon receipt of any such determination.

         (e)     If the Issuing Bank shall determine that a Force Majeure
Disruption Event shall have ceased to exist, then the Issuing Bank shall as
promptly as is possible under the circumstances give written notice of such
determination to the Depositary, the Joint Lead

                                       35
<PAGE>
Arrangers, the Administrative Agent, the Dealers and the Borrower, whereupon
the Issuing Bank shall revoke forthwith any instructions to the Depositary not
to issue and deliver CP Notes and the Borrower may, subject to concurrent or
prior prepayment of all Loans in accordance with Section 3.5(b), recommence
issuing CP Notes.  The Administrative Agent shall give prompt written notice to
the Banks upon receipt of notice of any such determination.

                                  ARTICLE III

                                     LOANS

         SECTION 3.1.      Loans.

         (a)     Notwithstanding anything to the contrary contained in Article
II, if at any time during the Commitment Period there shall occur a Market
Disruption Event, then, subject to the terms and conditions set forth in this
Agreement and the satisfaction of the conditions precedent to Extensions of
Credit set forth in Section 5.2, all unreimbursed LOC Advances made while such
Market Disruption Event is in existence (the "Market Disruption Obligations")
in respect of CP Notes duly issued and outstanding on the Market Disruption
Date shall be either paid in full by the Borrower on the maturity date of the
CP Notes to the Commercial Paper Account or shall automatically be converted to
loans on such date, upon the terms and conditions of this Agreement (such
loans, together with any loans made pursuant to Section 3.1(f), collectively,
"Loans"); provided, however, that no Loans may be made, based on such Market
Disruption Event, after the end of the period beginning on the Market
Disruption Date and ending on the date which is the earlier of (i) the Stated
Termination Date and (ii) 90 days after the relevant Disbursement Date (a
"Market Disruption Period"); provided, further, that (x) Loans may only be made
in connection with one Market Disruption Date prior to the first anniversary of
the Effective Date and only one Market Disruption Date thereafter, and (y) no
conversion of LOC Advances to Loans shall occur during the pendency of any
Default or Event of Default. Each Bank severally agrees, on the terms and
conditions of this Agreement, to make Loans to the Borrower from time to time
in an aggregate principal amount not in excess of the aggregate amount of such
Market Disruption Obligations arising from its Participation Fraction of all
unreimbursed LOC Advances. All Loans made pursuant to this paragraph (a) shall
initially be Base Rate Loans, which may, at the Borrower's option, be converted
into Eurodollar Loans in accordance with the terms and provisions of Section
3.3.

         (b)     At the time the conversion into Base Rate Loans becomes
effective pursuant to the preceding paragraph (a), the obligations of the
Borrower to the Issuing Bank under Section 2.3(a) (other than with respect to
accrued and unpaid interest) shall be discharged in an amount equal to the
aggregate principal amount of Loans paid by the Banks to the Administrative
Agent for the account of the Issuing Bank pursuant to Section 2.8(b).

         (c)     The Administrative Agent shall give the Banks prompt notice of
the existence of a Market Disruption Event as soon as it obtains notice thereof
and of the conversion of any unreimbursed LOC Advances into Loans.

                                       36
<PAGE>
         (d)     The Loans shall be made without any payments being made by the
Banks to the Borrower, but subject to the obligations of the Banks to the
Issuing Bank under Section 2.8(b).

         (e)     Each Borrowing shall be made from the several Banks ratably in
accordance with their Participation Fractions.

         (f)     During any Market Disruption Period on the terms and subject to
the conditions set forth in this Agreement, including the conditions precedent
specified in Section 5.2, the Borrower may borrow Loans other than under
Section 3.1(a) above under the Available Commitments (as defined below) in a
minimum amount of US$5,000,000 or in multiples of US$1,000,000 in excess
thereof on any Business Day; provided that the Borrower shall give the
Administrative Agent and the Issuing Bank notice as provided in Section 3.1(g).
As used in this paragraph (f), "Available Commitments" shall mean, as of any
date, the total amount of the Commitments minus the sum of (A) the aggregate
principal amount of CP Notes outstanding, (B) the aggregate principal amount of
unreimbursed LOC Advances that have not been converted into Loans pursuant to
Section 3.1(a), (C) the aggregate principal amount of any Loans made under this
Section 3.1 (whether or not still outstanding) and (D) any fees or other
amounts which the Borrower owes to any other party under the Principal
Documents.  Each Loan made pursuant to this Section 3.1(f) shall be in Dollars
and shall be made to an account of the Borrower in the United States.

         (g)     The Borrower may (but shall not be obligated to) request Loans
under Section 3.1(f) by giving notice to the Administrative Agent (with a copy
to the Issuing Bank) by 11:00 a.m. at least three Business Days prior to the
date of Borrowing.  Such notice (a "Notice of Borrowing") may be by telephone,
if promptly confirmed in writing in substantially the form of Exhibit M, and
may be made by facsimile transmission.  The Notice of Borrowing shall specify
(i) the aggregate amount of such Borrowing, which shall be in a minimum amount
equal to US$5,000,000 or in multiples of US$1,000,000 in excess thereof, (ii)
whether the Loans comprising such Borrowing shall bear interest based on the
Base Rate or LIBOR and (iii) if the Loans are to be Eurodollar Loans the
duration of the initial Interest Period applicable to such Loans.  The Notice
of Borrowing shall further certify that, as of the date of such Borrowing, (i)
each condition in Section 5.2 shall have been satisfied and (ii) a Market
Disruption Event has occurred and is continuing.  The Notice of Borrowing shall
not be revocable by the Borrower after the Administrative Agent has notified
any Bank thereof.

         (h)     (i)   Not later than 10:00 a.m., New York City time, on the

Business Day following the date on which a Notice of Borrowing is received, the
Administrative Agent shall notify each Bank by facsimile transmission or
telephone (any such facsimile transmission or telephone conversation to be
promptly confirmed by an original in writing) of the amount of its Loan to be
made under Section 3.1(f), based on its Participation Fraction.  On the
Disbursement Date for such Loan, each Bank shall make available the amount
thereof to the Administrative Agent at its address set forth on Schedule 1.1(b)
in immediately available funds, not later than 12:00 Noon, New York City time.

                  (ii) Unless the Administrative Agent shall have been notified
         in writing by any Bank prior to a borrowing that such Bank will not
         make the

                                       37
<PAGE>
         amount that would constitute its share of such borrowing available
         to the Administrative Agent, the Administrative Agent may assume
         that such Bank is making such amount available to the Administrative
         Agent, and the Administrative Agent may, in reliance upon such
         assumption, make available to the Borrower a corresponding amount.
         If such amount is not made available to the Administrative Agent by
         the required time on the Disbursement Date therefor, such Bank shall
         pay to the Administrative Agent, on demand, such amount with interest
         thereon, at a rate equal to the greater of (i) the Federal Funds
         Effective Rate and (ii) a rate determined by the Administrative Agent
         in accordance with banking industry rules on interbank compensation,
         for the period until such Bank makes such amount immediately
         available to the Administrative Agent.  A certificate of the
         Administrative Agent submitted to any Bank with respect to any
         amounts owing under this paragraph shall be conclusive in the absence
         of manifest error.  If such Bank's share of such borrowing is not
         made available to the Administrative Agent by such Bank within three
         Business Days after such Disbursement Date, the Administrative Agent
         shall also be entitled to recover, without prejudice to any rights
         the Borrower may have against such Bank, such amount with interest
         thereon at the rate per annum applicable to Base Rate Loans under
         this Agreement, on demand, from the Borrower.

         (i)  The Commitment of each Bank hereunder to make Loans is not
revolving in nature and any amounts borrowed hereunder and subsequently repaid
may not be reborrowed, except that the Commitments may be reinstated, as
provided in this Section 3.1 to permit the making of Loans in connection with a
Market Disruption Date occurring after the first anniversary of the Effective
Date to the extent that Loans made in connection with any Market Disruption
Date occurring prior to such anniversary have been repaid.

         SECTION 3.2.      Notes.

         (a)     The Loans made by each Bank shall, subject to the provisions of
Section 3.2(b) below, be evidenced by a promissory note of the Borrower in
substantially the form of Exhibit A-1 appropriately completed (each, a "Simple
Note"; and, collectively and together with any Mexican Notes issued pursuant to
Section 3.2(b) below, the "Notes"), in the principal amount of such Bank's
Commitment representing the obligation of the Borrower to pay to such Bank the
unpaid principal amount of all such Loans made by such Bank pursuant to Section
3.1, plus interest thereon as provided in Sections 3.6 and 3.7.  The date and
principal amount of each Loan made by such Bank, and the date and amount of
each payment or prepayment of the principal amount of each such Loan, shall be
recorded by such Bank on the Schedules annexed to its Simple Note and such
Schedules shall constitute prima facie evidence of the accuracy of the
information so recorded, provided, however, that the failure of any Bank to
make such recordation (or any error in such recordation) shall not affect the
obligations of the Borrower hereunder or under the Simple Notes.

         (b)     The Borrower agrees that whenever a Loan is made hereunder, or
at any time while a Loan made hereunder is outstanding, upon the request of any
Bank holding a Simple Note in respect of any portion of such Loan, the Borrower
shall issue to such Bank, against delivery to the Borrower, for cancellation,
of such Simple Note, one or more new promissory

                                       38
<PAGE>
notes in the form of Exhibit A-2 or Exhibit A-3 hereto appropriately completed
(each, a "Mexican Note" and collectively, the "Mexican Notes"), in the
respective principal amounts of each portion of the outstanding Loans that are
evidenced by the Simple Note.  Each Bank acknowledges and agrees that if it
requests a Mexican Note in respect of its portion of any Loan hereunder, then
it shall be obligated to accept Mexican Notes in respect of its portion of all
Loans hereunder, and that the Borrower shall have no further obligation to
issue to it any Simple Notes.  The Borrower further agrees that if at any time,
any Loan outstanding hereunder shall convert from a Base Rate Loan to a
Eurodollar Loan or from a Eurodollar Loan to a Base Rate Loan, whether at the
election of the Borrower or otherwise, the Borrower shall issue to each Bank
holding a Mexican Note in respect of such Loan, a new Mexican Note that
accurately reflects the appropriate interest rate determinant, against delivery
to the Borrower, for cancellation, of the Mexican Note that reflected the
pre-conversion interest rate determinant.

         SECTION 3.3.      Procedure for Conversion. Loans shall be made in
accordance with Section 3.1 and, subject to Section 3.8 and so long as no
Default or Event of Default then exists, the Borrower may convert Base Rate
Loans to Eurodollar Loans on any Eurodollar Business Day; provided that the
Borrower shall give the Administrative Agent irrevocable written or facsimile
notice in the form of a conversion certificate in substantially the form of
Exhibit E (the "Conversion Certificate"), which Conversion Certificate must be
received by the Administrative Agent prior to 11:00 a.m., New York City time,
three Eurodollar Business Days prior to the proposed conversion date.  Upon the
receipt of a Conversion Certificate relating to such Eurodollar Loans, the
Administrative Agent shall immediately, and in any event by 6:00 p.m., New York
City time, on the same Business Day as the date of receipt, notify each Bank
thereof (which notice shall in all events be confirmed promptly in writing or
by facsimile).

         SECTION 3.4.      Repayment. The Borrower shall pay to the
Administrative Agent, at such account as set forth on Schedule 1.1(b),  for the
account of each Bank the unpaid principal amount of each of such Bank's Loans on
the Maturity Date therefor.

         SECTION 3.5.      Prepayments.

         (a)     Optional Prepayments.

                 (i)  The Borrower may (A) upon notice to the Administrative
         Agent received not later than one Business Day prior to the date for
         such repayment, prepay Base Rate Loans in whole or in part, without
         premium or penalty, and (B) subject to the indemnity provisions of
         Section 4.11, prepay Eurodollar Loans upon at least five Eurodollar
         Business Days irrevocable notice to the Administrative Agent,
         specifying the date and amount of prepayment. Each such optional
         prepayment shall be applied to prepay the Loans specified by the
         Borrower in its notice of prepayment ratably among the several Banks.

                 (ii)  Upon receipt of a notice of prepayment, the
         Administrative Agent shall promptly notify each Bank thereof. If such
         notice is given, the Borrower shall make such prepayment and the
         payment amount specified in such notice shall be due and payable on
         the date specified therein, together with accrued interest to, and any
         other amounts then due on, each such date on the amount

                                       39
<PAGE>
         prepaid. Prepayments of Loans shall be in a minimum amount
         equal to US$5,000,000 and in multiples of US$1,000,000 in excess
         thereof, or, if less, the aggregate principal amount of Loans then
         outstanding. Amounts prepaid may not be reborrowed.

         (b)     Mandatory Prepayments.

                 (i)  If at any time the Outstanding Extensions of Credit shall
         exceed the sum of the Commitments as then in effect, the Borrower
         shall immediately prepay the outstanding Loans and repay LOC
         Advances, if any, to the extent of such excess.

                 (ii)  Upon the determination that a Market Disruption Event has
         ceased to exist (as determined in accordance with the terms and
         provisions of Section 2.9(d) or 2.9(e)), the Borrower shall, within
         five Business Days after notice thereof to the Administrative Agent,
         prepay all Loans outstanding.

                 (iii)  Amounts applied to the prepayment of Loans pursuant to
         this Section 3.5(b) shall be applied to prepay ratably the Loans
         among the several Banks.

                 (iv)  The application of any prepayment pursuant to this
         Section 3.5(b) shall be made, first, to Base Rate Loans and, second, to
         Eurodollar Loans. Each prepayment of the Loans under this Section
         3.5(b) shall be accompanied by accrued interest to the date of such
         prepayment on the amount prepaid.  Any prepayment of Eurodollar Loans
         pursuant to this Section shall be subject to the provisions of
         Section 4.11. Amounts prepaid may not be reborrowed.

         SECTION 3.6.      Interest Rates and Payment Dates.

         (a)     The Eurodollar Loans comprising each Tranche shall bear
interest for each day during the Interest Period for such Tranche on the unpaid
principal amount thereof at a rate per annum equal to LIBOR determined for such
Interest Period plus the Eurodollar Margin.

         (b)     The Base Rate Loans shall bear interest for the period from and
including the date of such Loans on the unpaid principal amount thereof at a
rate per annum equal to the Base Rate plus the Base Rate Margin.

         (c)     If all or a portion of the principal amount of any of the Loans
shall not be paid when due (whether at the stated maturity, by acceleration or
otherwise), each Eurodollar Loan shall bear interest at LIBOR plus the
Eurodollar Margin plus 2.0% and any overdue principal amount of Base Rate Loans
shall bear interest at a rate per annum equal to the Base Rate plus the Base
Rate Margin plus 2.0%, in each case from the date of such non-payment until
paid in full (both after and before judgment) and shall be payable on demand.
If all or any portion of (A) any interest payable on the principal amount of
any Loan or (B) any fee or other amount payable hereunder shall not be paid
when due, such overdue amount shall (to the fullest extent permitted by
applicable law) bear interest at a rate per annum equal to the Base Rate plus
the Base Rate

                                       40
<PAGE>
Margin plus 2.0% from the date of such non-payment until such amount is paid in
full (after as well as before judgment) and shall be payable on demand and on
the date of payment in full.

         (d)     Except as otherwise provided in paragraph (c), interest shall
be payable in arrears on each Interest Payment Date and on the Maturity Date.

         SECTION 3.7.      Computation of Interest.

         (a)     Interest in respect of Eurodollar Loans and Base Rate Loans
shall be calculated on the basis of a 360 day year for the actual days elapsed
except that, with respect to Base Rate Loans the rate of interest on which is
calculated on the basis of the Prime Rate, the interest thereon shall be
calculated on the basis of a 365- (or 366-, as the case may be) day year for
the actual days elapsed.  The Administrative Agent shall, as soon as
practicable, notify the Borrower and the Banks of each determination of LIBOR;
provided, however, that any failure to do so shall not relieve the Borrower of
any liability hereunder.  Any change in the interest rate on a Loan resulting
from a change in the Base Rate shall become effective as of the opening of
business on the day on which such change in the Base Rate is announced.  The
Administrative Agent shall as soon as practicable notify the Borrower and the
Banks of the effective date and the amount of each such change; provided,
however, that any failure to do so shall not relieve the Borrower of any
liability hereunder.

         (b)     Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Banks in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower or any Bank, deliver
to the Borrower or such Bank, as the case may be, a statement showing the
quotations used by the Administrative Agent in determining any interest rate
pursuant to Section 3.6(a).

         SECTION 3.8.      Inability to Determine Interest Rate.  In the event
that the Administrative Agent shall have reasonably determined (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the interbank eurodollar market, adequate means do
not exist for ascertaining LIBOR applicable pursuant to Section 3.6(a) for any
requested Interest Period with respect to a proposed Loan that the Borrower has
requested be converted into or continued as a Eurodollar Loan, the
Administrative Agent shall forthwith give notice by facsimile of such
determination to the Borrower and each Bank at least one day prior to the
proposed conversion date or continuation date for such Eurodollar Loan. Until
such notice has been withdrawn, no conversion of Base Rate Loans to Eurodollar
Loans under Section 3.3 or otherwise may be made and all Eurodollar Loans shall
be converted to Base Rate Loans on the last day of the then current Interest
Period for each Tranche (unless such last day shall also be the Maturity Date
for such Tranche).

         SECTION 3.9.      Continuation Option. Any Eurodollar Loans may be
continued as such upon the expiration of the then current Interest Period with
respect thereto by the Borrower giving written notice to the Administrative
Agent not later than 11:00 a.m. New York City time, three Eurodollar Business
Days prior to the last day of such Interest Period in accordance with the
applicable provisions of the term "Interest Period" set forth in Section 1.1,
of the length of the next Interest Period to be applicable to such Loans;
provided, however, that

                                       41
<PAGE>
no Eurodollar Loan may be continued as such (a) when any Event of Default has
occurred and is continuing and the Administrative Agent, with the consent of
the Majority Banks, has determined that such a continuation is not appropriate
and (b) after the date that is one month prior to the Maturity Date with
respect to such Eurodollar Loan and provided, further, that if the Borrower
shall fail to give any required notice as described above in this Section 3.9
or if such continuation is not permitted pursuant to the preceding proviso such
Loans shall be automatically converted to Base Rate Loans on the last day of
such then expiring Interest Period.  Upon receipt of such notice, the
Administrative Agent shall promptly give the Banks notice of the same.

         SECTION 3.10.     Maximum Interest Rate. Anything in this Agreement or
any other Principal Document to the contrary notwithstanding, the interest rate
on any Loan or any LOC Advance shall in no event be in excess of the maximum
permitted by applicable law.

                                   ARTICLE IV

                TERMS APPLICABLE TO LETTERS OF CREDIT AND LOANS

         SECTION 4.1.      Reduction of Commitments. The Borrower shall have the
right, upon not less than 30 days' notice to the Administrative Agent and the
Issuing Bank and without premium or penalty (other than as may arise pursuant
to Section 4.11), from time to time to permanently reduce on a pro rata basis
the Commitments and the Stated Amount of the Letter of Credit in part by an
aggregate minimum amount of US$10,000,000 or any integral multiple of
US$5,000,000 in excess thereof; provided, however, that no reduction of the
Commitments shall be permitted if, after giving effect thereto, the Commitments
would be less than $50,000,000; provided, further, however, that no reduction
of the Commitments shall be permitted if, after giving effect thereto and to
any repayment or prepayment of Loans to be made on the effective date thereof
with funds other than the proceeds of CP Notes to be issued on such date, the
aggregate Outstanding Extensions of Credit would exceed the Commitments as so
reduced and determined on such date.  Notwithstanding the foregoing sentence to
the contrary, the $50,000,000 limitation and the 30 days' notice requirement,
which are contained in the foregoing sentence, shall not apply to any reduction
of Commitments being made in connection with an extension of the Stated
Termination Date or the refunding of the Obligations pursuant to documentation
satisfactory to the Issuing Bank and the Administrative Agent.  Any reduction
of the Commitments shall be irrevocable.  Promptly upon the receipt by the
Administrative Agent of such notice, the Administrative Agent shall notify the
Banks of such reduction.  Promptly upon receipt by the Issuing Bank, the
Issuing Bank shall notify the Depositary (with a copy to the Administrative
Agent, the Rating Agencies and the Dealers) by notice substantially in the form
of Annex C to the Letter of Credit.  If the Commitments shall be reduced, all
Fees, accrued but unpaid in respect of that portion of the Commitments by which
the Commitments have been reduced, shall be immediately due and payable.  Any
reduction of the Commitments pursuant to this Section 4.1 shall be effective on
the later to occur of: (a) the date on which the Outstanding Extensions of
Credit do not exceed the aggregate Commitments (as so reduced) and (b) the
expiration of such 30 day notice period.  Outstanding CP Notes may not be
redeemed prior to maturity with the proceeds of any drawing under the Letter of
Credit.  In the event that the Commitments are reduced pursuant hereto, the
Borrower shall have no right to a refund of any fees previously paid in
connection with the Principal Documents, including, but not limited to, any
refund of Letter of Credit Fees or Up-Front Fees.  Any reduction of the
Commitments

                                       42
<PAGE>
pursuant to this Section 4.1 shall cause the Stated Amount of the Letter of
Credit to be reduced by the same amount.

         SECTION 4.2.      Termination and Extension.

         (a)     The Commitments shall terminate on the Termination Date, and
any Loans outstanding on the Termination Date shall thereupon be due and
payable, together with all interest and Fees accrued thereon or in respect
thereof and any amounts payable pursuant to Section 4.11.

         (b)     As used in this Agreement, "Termination Date" shall mean the
earlier of (a) the Stated Termination Date and (b) such earlier date as the
Commitments may terminate as herein provided.

         (c)     The Borrower shall have the right on any Business Day prior to
the Stated Termination Date but no sooner than the later of (1) the Drawing
Deadline for all CP Notes validly issued and outstanding pursuant to the terms
of this Agreement and the Depositary Agreement and (2) (unless any payments by
the Borrower hereunder or under the CP Notes shall have become subject to
Mexican withholding taxes) the six-month anniversary of the Effective Date (the
"Elected Termination Date"), upon not less than 30 days' notice to the
Administrative Agent and the Issuing Bank, to terminate the Commitments;
provided, however, that if a Force Majeure Disruption Event or a CP Disruption
Event precipitated by a downgrade in the credit rating of the Issuing Bank has
occurred and is continuing, the Borrower shall have the right to terminate the
Commitments upon not less than 10 days' notice; provided, further that on or
prior to the Elected Termination Date, (i) the Letter of Credit shall have been
terminated and the Issuing Bank shall have delivered notice to the Depositary
of such termination pursuant to the Depositary Agreement, (ii) the unpaid
principal amount of the Notes, together with accrued interest thereon and any
Fees and all other Obligations accrued hereunder, shall have been paid, (iii)
the Borrower shall have paid to the Issuing Bank the amount agreed to by the
Issuing Bank and the Borrower in the LOC Fee Letter, and (iv) the Issuing Bank
or the Borrower shall have instructed the Depositary to cease issuing CP Notes
as provided in the Depositary Agreement.  Nothing in this Section 4.2 shall
impair the obligation of Issuing Bank to make payments in accordance with the
Letter of Credit with respect to maturing CP Notes which have been validly
issued and are outstanding pursuant to the terms of this Agreement and the
Depositary Agreement.  Notwithstanding the foregoing to the contrary, the 30
days' notice requirement shall not apply to any termination of Commitments
being made in connection with an extension of the Stated Termination Date or
the refunding of the Obligations pursuant to documentation satisfactory to the
Issuing Bank and the Administrative Agent.

         (d)     The term of this Agreement may be extended by agreement of the
Borrower, all the Banks, the Joint Lead Arrangers, the Arrangers, the Issuing
Bank, the Documentation Agent and the Administrative Agent; not earlier than 90
days prior to the Stated Termination Date on such terms and conditions as such
parties may agree in writing provided, however, that none of the aforementioned
parties are obliged to agree to such an extension (any such agreement to be in
the sole discretion of such party).

         SECTION 4.3.      Commitments Exceeded. If at any time the aggregate
Outstanding Extensions of Credit shall exceed the amount of the Commitments,
the Borrower shall deliver to the Issuing Bank, in immediately available funds,
an amount equal to such excess; provided, however, that the provisions of this
Section 4.3 shall not apply to the extent (but only to the extent) such excess
is reduced as a result of prepayment of Loans pursuant to Section 3.5, and
provided, further, that such funds shall be transferred by the Issuing Bank to
the Commercial Paper Account at the Depositary, and no such funds may be
applied to reimburse the Issuing Bank for any LOC Advance in connection
therewith, except after 1:30 p.m., New York City time, on the day such LOC
Advance is made.

         SECTION 4.4.      Notice to Depositary. To enable the Depositary to
determine the Maximum Commercial Paper Amount from time to time, the
Administrative Agent shall send to the Depositary, with a copy to the Borrower,
a notice by facsimile or, failing that, by hand, in substantially the form of
Exhibit F at the close of business each day on which (a) any LOC Advance has
not been reimbursed by the Borrower at or prior to 5:00 p.m., New York City
time, on the day such LOC Advance was made, (b) Loans have been made hereunder,
(c) the Administrative Agent or the Issuing Bank have received monies in
payment or prepayment of outstanding Loans or unreimbursed LOC Advances or (d)
the aggregate amount of Commitments change.  The Issuing Bank shall furnish to
the Administrative Agent such information as the Administrative Agent may
require in connection with the preparation of such notices.

         SECTION 4.5.      Fees.

         (a)     Participation Fee. The Borrower will pay to the Administrative
Agent, for the account of each Bank (including the Issuing Bank), a quarterly
participation fee (the "Participation Fee") on its Participation Fraction of
the aggregate Commitments less the average daily amount of any Loans
outstanding from time to time and unreimbursed LOC Advances on which interest
is accruing under Section 2.3(b), for the period from and including the Date of
Issuance to and including the Termination Date.  The Participation Fee shall be
payable in arrears on the last day of March, June, September and December of
each year and on the Termination Date (provided that if any such day is not a
Business Day, the Participation Fee shall be payable on the next preceding
Business Day), and shall be calculated at the rate per annum set forth below
based on the Consolidated Leverage Ratio as of the last day of the period of
the four fiscal quarters most recently ended prior to such payment date:

year for the actual days elapsed.

         SECTION 4.6.     Maximum Interest or Discount. Anything in this
Agreement or the Depositary Agreement to the contrary notwithstanding, the
Borrower shall not issue any CP Notes if the interest thereon or the discount

law.

         SECTION 4.7.      Pro Rata Treatment and Payments.

         (a)     Each Borrowing by the Borrower from the Banks (except as
otherwise provided in Section 4.9) shall be made pro rata according to the
respective Participation Fractions of the Banks.

         (b)     Any reduction of the Commitments shall be made pro rata

at the Administrative Agent's office set forth in Section 13.7, which shall be
maintained in New York, New York, in Dollars and in immediately available

liability

                                       45
<PAGE>
to any Bank with respect to any amount for which the Borrower has made payment
to the Administrative Agent, for the account of such Bank.

         SECTION 4.8.      Taxes.

         (a)     All payments made by the Borrower under this Agreement and any
other Principal Document shall be made free and clear of, and without deduction
for or on account of, any present or future income, stamp, sales or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings,
imposed, levied, collected, withheld or assessed by any Governmental Authority
of Mexico or any other jurisdiction from which payment is made or is deemed to
be made (excluding the following "Excluded Taxes": net income taxes or
franchise taxes imposed on any recipient of such payment (each a "Payee") as a
result of a present or former connection between the jurisdiction of the
Governmental Authority imposing such tax and the Payee (other than any such
connection arising solely from the Payee having executed, delivered or
performed its obligations or received a payment under, or enforced, this
Agreement) and withholding taxes to the extent imposed by reason of any Payee
or its assignees or participants, if any, failing to make reasonable commercial
efforts to maintain its registration with Hacienda).  If any such non-excluded
taxes, levies, imposts, duties, charges, fees, deductions or withholdings
("Non-Excluded Taxes") are required to be withheld from any amounts payable to
any Payee hereunder, (subject to the right of the Borrower to contest any such
requirement in good faith, so long as proper reserves are maintained and each
Payee hereunder is paid the full amounts payable hereunder including any
gross-up payable) the Borrower shall pay such Non-Excluded Taxes to the
appropriate taxing authority, and the amounts payable to each such Payee shall
be increased by such additional amounts (the "Additional Amounts") necessary to
yield to such Payee (after payment of all Non-Excluded Taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts specified
in this Agreement.  Whenever any Non-Excluded Tax is payable by the Borrower,
as promptly as possible thereafter, the Borrower shall send to the
Administrative Agent, for the account of such Payee, a certified copy by a
Responsible Officer of the Borrower of a stamped filed receipt showing payment
thereof.  If the Borrower fails to pay any Non-Excluded Taxes when due to the
appropriate taxing authority or fails to remit to the Administrative Agent the
required receipts or other required documentary evidence, the Borrower shall
indemnify the affected Payees for any incremental taxes, interest or penalties
that may become payable by any such Payee as a result of any such failure.
This indemnity and agreement shall survive termination of the Agreement and
payment of the Loans and CP Notes.

         (b)     Each Payee shall, from time to time at the request of the
Borrower, the Issuing Bank or the Administrative Agent, furnish to the
Borrower, the Issuing Bank or the Administrative Agent, as the case may be,
such documentation as may be required to establish any available exemption
from, or reduction in the amount of, otherwise applicable Non-Excluded Taxes.
The Borrower, the Issuing Bank and the Administrative Agent shall be entitled
to rely upon the accuracy of any such documentation furnished to it by any
Payee and shall have no obligation to indemnify such Payee for any incremental
taxes, interest or penalties that may become payable by such Payee solely as a
result of any inaccuracy contained therein or the Payee's failure to furnish
such documentation.

         SECTION 4.9.      Illegality. Notwithstanding any other provisions
herein, if any Requirement of Law or any change therein or in the
interpretation or application thereof shall make it unlawful for any Bank to
make or maintain Eurodollar Loans as contemplated by this Agreement, then such
Bank may give notice thereof to each of the Borrower, the Issuing Bank, the
Administrative Agent, and the Depositary, and upon the giving of such notice
(a) the Commitment of such Bank hereunder to make Eurodollar Loans shall
forthwith be canceled and (b) such Bank's Loans then outstanding as Eurodollar
Loans, if any, shall be converted to Base Rate Loans on the last day of the
Interest Period therefor or within such earlier period as required by law.  If
any such conversion of a Eurodollar Loan is made on a day which is not the last
day of the Interest Period therefor, the Borrower shall pay to such Bank such
amounts, if any, as may be required pursuant to Section 4.11.

         SECTION 4.10.     Requirements of Law.

         (a)     If, after the Effective Date, and as a result of the adoption
of any law, regulation, treaty or official directive or request (whether or not
having the force of law) or any change therein or any introduction thereof
(which such change or introduction is publicly announced through official
governmental, regulatory or other customary means after the Effective Date) or
compliance therewith by the Borrower, the Administrative Agent, the Issuing
Bank or any Bank (or any corporation controlling such Bank) including those
relating to taxation, reserves, special deposit, cash ratio, liquidity, capital
adequacy or Eurocurrency Liabilities or other requirement or any other form of
banking or monetary requirements or controls, any of the following shall occur:

                 (i)   the cost to any Bank or the Issuing Bank of maintaining
         its Commitment or maintaining the Letter of Credit or making or
         maintaining its Loans or its participation in the Letter of Credit
         Facility is increased by an amount determined by such Bank or Issuing
         Bank to be material; or

                 (ii)   any amount receivable by any Bank or the Issuing Bank is
         reduced by an amount determined by such Bank or Issuing Bank to be
         material as a result of maintaining its Commitment or maintaining the
         Letter of Credit or maintaining its Loans or its participation in the
         Letter of Credit Facility; or

                 (iii)   the rate of return on such Bank's (or its controlling
         corporation's) capital is reduced as a consequence of its obligations
         hereunder or under or in respect of the Letter of Credit to a level
         below that which such Bank could have achieved but for such adoption,
         change or introduction (taking into consideration such Bank's or such
         corporation's policies with respect to capital adequacy) by an amount
         deemed by such Bank or the Issuing Bank to be material;

in the case of each of clauses (i), (ii) and (iii) other than any increase in
or incurrence of cost, reduction in yield or other return or additional payment
resulting from Excluded Taxes, then and in each such case:

                 (A) such Bank or the Issuing Bank or the Administrative Agent
     on its own behalf (each of the foregoing, an "Affected Bank") shall
     notify the Borrower through the

                                       47
<PAGE>
     Administrative Agent in writing of such event promptly upon its becoming
     aware of the event entitling it to make a claim; and

                 (B) upon demand from time to time by such Affected Bank through
     the Administrative Agent, the Borrower shall pay to the Administrative
     Agent for the account of such Affected Bank such amount as shall
     compensate such Affected Bank for such increased cost, reduced amount
     receivable or reduction in rate of return. The certificate of such
     Affected Bank specifying the amount of such compensation shall be
     conclusive save in the case of manifest error.

         (b)     If an Affected Bank shall request compensation under this
Section 4.10, such Bank shall furnish to the Borrower a statement setting forth
the basis for requesting such compensation.

         (c)     The covenants and agreements set forth in this Section 4.10
shall survive the termination of this Agreement and the payment of the
outstanding Loans and CP Notes.  Failure or delay on the part of any Bank or
the Issuing Bank to demand compensation pursuant to this Section 4.10 shall not
constitute a waiver of such Bank's or the Issuing Bank's right to demand
compensation; provided that the Borrower shall not be required to compensate a
Bank or the Issuing Bank, as applicable, pursuant to this Section 4.10 for any
increased costs or reductions incurred more than 180 days prior to the date
that such Bank or the Issuing Bank, as the case may be, notifies the Borrower
of the event giving rise to such increased costs or reductions and of such
Bank's or such Issuing Bank's intention to claim compensation therefor; and
provided further that, if the event giving rise to such increased costs or
reduction is retroactive, then the 180 day period referred to above shall be
extended to include the period of retroactive effect thereof.

         SECTION 4.11.     Funding Indemnity. The Borrower agrees to indemnify
each Bank and to hold such Bank harmless from any actual loss or expense
(excluding loss of profit) which such Bank may sustain or incur as a
consequence of (a) default by the Borrower in payment when due (by acceleration
or otherwise) of the principal amount of or interest on any Eurodollar Loans or
any Base Rate Loans of such Bank, (b) default by the Borrower in converting
Base Rate Loans into Eurodollar Loans after the Borrower has given a Conversion
Certificate in accordance with Section 3.3, (c) default by the Borrower in
making any prepayment after the Borrower has given a notice in accordance with
Section 3.5(a), (d) default by the Borrower in converting Eurodollar Loans into
Base Rate Loans pursuant to Section 4.9 , and (e) the making by the Borrower of
a prepayment of a Eurodollar Loan, on a day which is not the last day of the
Interest Period with respect thereto (whether or not the Administrative Agent
or such Bank has previously consented to such prepayment), including any such
loss or expense arising from interest or fees payable by such Bank to lenders
of funds obtained by it in order to maintain its Eurodollar Loans hereunder as
set forth in a certificate of such Bank delivered to the Borrower through the
Administrative Agent.  This covenant shall survive termination of this
Agreement and payment of the Loans and CP Notes.

                                       48
<PAGE>
         SECTION 4.12.     Sharing of Payments, Etc.

         (a)     If, other than as expressly provided elsewhere herein, any Bank
shall obtain on account of the Obligations owing to it any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or
otherwise) in excess of its Participation Fraction of payments on account of
the Obligations obtained by all the Banks, such Bank shall forthwith (i) notify
the Administrative Agent of such fact, and (ii) purchase from the other Banks
such participations in such Obligations made by them as shall be necessary to
cause such purchasing Bank to share the excess payment ratably with each of
them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from the purchasing Bank, such purchase shall to that
extent be rescinded and each other Bank shall repay to the purchasing Bank the
purchase price paid therefor, together with an amount equal to such paying
Bank's Participation Fraction (according to the proportion of (A) the amount of
such paying Bank's required repayment to (B) the total amount so recovered from
the purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered.  The
Administrative Agent will keep records (which shall be conclusive and binding
in the absence of manifest error) of participations purchased pursuant to this
Section 4.12 and will in each case notify the Banks and the Borrower following
any such purchases.

         (b)     The Borrower agrees that any Bank so purchasing a participation
from another Bank pursuant to this Section 4.12 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off, but subject to Section 13.12) with respect to such participation as
fully as if such Bank were the direct creditor of the Borrower in the amount of
such participation.

         SECTION 4.13.  Change of Lending Office.

         Each Bank agrees that, upon the occurrence of any event giving rise to
the operation of Section 4.8, 4.9 or 4.10(a) as to it, it will use its
reasonable best efforts to avoid or minimize the consequences of such event;
provided, however, that such action shall not, in the judgment of such Bank, as
the case may be, be illegal or economically or otherwise disadvantageous to it.
If such Bank is entitled to compensation for the events specified under Section
4.8 or 4.10(a), or is prevented from making Eurodollar Loans as a result of the
operation of Section 4.9, it shall endeavor for a period of 30 days to designate
a different office for any Obligation or Letter of Credit affected by such event
if such designation will avoid the need for, or reduce the amount of, such
compensation and will not, in the sole opinion of such Bank, result in any
economic, legal or regulatory or other disadvantage to such Bank or any of its
affiliates.

         SECTION 4.14.     Replacement of Banks. The Borrower shall be permitted
to replace any Bank that (a) requests reimbursement for amounts owing pursuant
to Section 4.8 or 4.10(a), (b) is prevented from making Eurodollar Loans as a
result of the operation of Section 4.9 or (c) defaults in its obligation to
make Loans hereunder, with a replacement financial institution; provided that
(i) such replacement does not conflict with any Requirement of Law, (ii) no
Event of Default shall have occurred and be continuing at the time of such
replacement, (iii) prior to any such replacement, such Bank shall have taken no
action under Section 4.13 so as to eliminate the continued need for payment of
amounts owing pursuant to Section 4.8 or 4.10(a) or the operation of Section
4.9, (iv) the replacement financial institution shall purchase, at par, all

                                       49
<PAGE>
Loans, unreimbursed LOC Advances and other amounts owing to such replaced Bank
on or prior to the date of replacement, (v) the Borrower shall be liable to
such replaced Bank under Section 4.11 if any Eurodollar Loan owing to such
replaced Bank shall be purchased other than on the last day of the Interest
Period relating thereto, (vi) the replacement financial institution, if not
already a Bank, shall be reasonably satisfactory to the Administrative Agent
and the Issuing Bank, (vii) the replaced Bank shall be obligated to make such
replacement in accordance with the provisions of Section 13.10 (provided that
the Borrower shall be obligated to pay the registration and processing fee
referred to therein), (viii) until such time as such replacement shall be
consummated, the Borrower shall pay all additional amounts (if any) required
pursuant to Section 4.8 or 4.10(a), as the case may be, and (ix) any such
replacement shall not be deemed to be a waiver of any rights that the Borrower,
the Administrative Agent, the Issuing Bank or any other Bank shall have against
the replaced Bank.

the execution, delivery or performance of this Agreement or any of the other

or any judgment, decree, order or permit applicable to the Borrower, or will
conflict with or will result in any breach of, any of the terms, covenants,
conditions or provisions of, or constitute a default under, or result in the

or bound or to which it may be subject or violate any provision of the estatutos

any other Principal Document or the transactions contemplated hereby or thereby
or (b) which individually or in the aggregate could be reasonably expected to
have a Material Adverse Effect.  Except with respect to any matters that,

         SECTION 6.5.      Governmental Approvals. Assuming that the Letter of
Credit will be duly issued by the Issuing Bank and will constitute a valid
obligation of the Issuing Bank, no order, permission, consent, approval,

with, or exemption by, any Governmental Authority is required by the Borrower
to authorize, or is required in connection with, the execution, delivery and

         (a)     The audited financial statements of the Borrower dated December
31, 1999, 2000 and 2001, and unaudited financial statements as of June 30, 2002

all taxes due except such taxes as are being contested in good faith for which

<PAGE>
         SECTION 6.8.      Investment Company Act. The Borrower is not an
"investment company" required to be registered under the Investment Company Act

supplied by the Borrower to the Administrative Agent, the Documentation Agent,
the Issuing Bank, the Joint Lead Arrangers, the Arrangers and the Banks
relating to the Borrower, viewed in the aggregate, was true and accurate in all
material respects as of the date supplied, and did not as of such date, and
does not, in each case viewed in the aggregate, omit to state any material
information necessary to make the information therein contained, in light of
the circumstances under which such information was supplied, not misleading.

         SECTION 6.10.     Absence of Default. No Default or Event of Default
has occurred and is continuing.

         SECTION 6.11.     Obligations Pari Passu; Recourse; Liens. The

properties or Indebtedness of the Borrower or its Subsidiaries other than liens
permitted or required by this Agreement or the other Principal Documents,
including, without limitation, Permitted Liens.

         SECTION 6.12.     Withholding Tax. As of the Effective Date, there is

by or in Mexico or any political subdivision or taxing authority thereof or
therein either (i) on or by virtue of the execution or delivery of this
Agreement or any of the other Principal Documents or the Fee Letters or (ii) on
any payment to be made by the Borrower pursuant to this Agreement or any of the
other Principal Documents or any of the Fee Letters to any Person, except that
payments of interest under this Agreement (including payments made in excess of
the original issue price of the CP Notes) and fees payable hereunder and under
any Fee Letter will be subject to a Mexican withholding tax at a rate of 4.9% so
long as the payee is a commercial bank or other financial institution registered
with Hacienda and, if applicable, the Borrower complies with general rules
issued by Hacienda. As of the Effective Date, the Borrower is permitted under
applicable law, to make all payments pursuant to this Agreement or any of the
other Principal Documents, or the Fee Letters free and clear of all taxes,
levies, imposts, deductions, charges or withholdings imposed, levied or made by
or in Mexico or any political subdivision or taxing authority thereof, as
provided in this Agreement or in any other of the Principal Documents, without
any liability to be borne by the payee in connection with such Mexican
withholding tax to the extent that the Borrower has complied with its
obligations in Section 4.8 of this Agreement and the corresponding provisions of
the other Principal Documents to pay to the appropriate Mexican authorities
applicable withholding taxes required to be paid by the Borrower.

         SECTION 6.13.      Proper Form; No Filing. Each Principal Document is
(or, in the case of any Note or any CP Note, will be, upon the issuance thereof
in accordance herewith) in proper legal form for the enforcement thereof in
Mexico against the Borrower; provided, however, that if any legal proceedings
are brought in a court of Mexico for the enforcement against the Borrower, of
this Agreement and the other Principal Documents, a Spanish

                                       56
<PAGE>
translation of such documents prepared by a translator approved by the Mexican
court would have to be approved by such court after the Borrower has been given
the opportunity to be heard with respect to the accuracy of the translation,
and proceedings would thereafter be based on the translated documents.  To
ensure the legality, validity, enforceability or admissibility in evidence of
this Agreement and the other Principal Documents in Mexico it is not necessary
that this Agreement or any other document be filed or recorded with any
Governmental Authority in Mexico or be notarized, or that any stamp or similar
tax be paid on or in respect of this Agreement or any of the other Principal
Documents.

         SECTION 6.14.     Choice of Law. In any action or proceeding involving
the Borrower arising out of or relating to this Agreement in any court of
Mexico, a Bank, the Issuing Bank, the Joint Lead Arrangers, the Arrangers, the
Documentation Agent and the Administrative Agent would be entitled to the
recognition and effectiveness of the choice of law provisions of Section 13.5.

         SECTION 6.15.     Immunity. The Borrower is subject to suit in Mexico
and neither it nor its property has any right of immunity, on the grounds of
sovereignty or otherwise, from any legal action, suit or proceeding, set-off or
counterclaim, the jurisdiction of any competent court and service of process,
attachment or execution in Mexico with respect to its obligations, liabilities,
or any other matter under or arising out of or in connection with this
Agreement or any other Principal Document, and to the extent that the Borrower
or its property may have or may hereafter become entitled to any such right of
immunity it has effectively waived such right under Section 13.16; provided,
that the Concession Title may not be transferred to any Person without the
prior consent of Mexico.  The waiver by the Borrower described in the
immediately preceding sentence is a legal, valid and binding obligation
thereof.  The foregoing waiver is intended to be effective to the fullest
extent now or hereafter permitted by the applicable law of any jurisdiction in
which any suit, action or proceeding with respect to this Agreement may be
commenced.  The performance of this Agreement and the other Principal Documents
by the Borrower constitutes private and commercial acts rather than
governmental or public acts.

         SECTION 6.16.     Status of Concession. The Concession Title is in full
force and effect and no investigation or proceeding seeking the termination or
revocation of the Concession Title has been initiated or attempted.

         SECTION 6.17.     Properties. (a)     The Borrower has good title to,
or valid leasehold interests in, all its real and personal property
material to its business, except for minor defects in title that do not

or to utilize such properties for their intended purposes.

         (b)     The Borrower owns, or is licensed to use, all trademarks,
tradenames, copyrights, patents and other intellectual property material to its
business, and the use thereof by the Borrower 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 Material Adverse
Effect.

                                       57

         SECTION 6.18.     Subsidiaries. The Subsidiaries listed on
Schedule 6.18 hereto constitute the only Subsidiaries of the Borrower as at the
date hereof.

         SECTION 6.19.     Federal Regulations. No part of the proceeds of any
Loans will be used for "buying" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U as now and
from time to time hereafter in effect or for any purpose that violates the
provisions of the Regulations of the Board.  If requested by any Bank or the
Administrative Agent, the Borrower will furnish to the Administrative Agent and
each Bank a statement to the foregoing effect in conformity with the
requirements of FR Form G-3 or FR Form U-1, as applicable, referred to in
Regulation U.

         SECTION 6.20.     Labor Matters. Except as, in the aggregate, could not
reasonably be expected to have a Material Adverse Effect: (a) there are no
strikes or other labor disputes against the Borrower pending or, to the
knowledge of the Borrower, threatened; (b) hours worked by and payment made to
employees of the Borrower have not been in violation of any applicable
Requirement of Law dealing with such matters; and (c) all payments due from the
Borrower on account of employee health and welfare insurance have been paid or
accrued as a liability on the financial statements of the Borrower.

             business, not relating to any Indebtedness, and that do not,
             individually or in the aggregate, detract from the value of the
             property or assets of the Borrower or any of its Subsidiaries in
             any manner material to the Borrower or to any of its Subsidiaries,

                 (vi)    with respect to a Subsidiary and imposed pursuant to an
     agreement that has been entered into for the sale or disposition of all or

     Subsidiary; or

                 (vii)   for the benefit of any holder of a Lien permitted under
     Section 8.11.

Nothing contained in this Section 8.7 shall prevent the Borrower or any of its
Subsidiaries from (1) creating, incurring, assuming or suffering to exist any
Liens otherwise permitted by Section 8.11 or (2) restricting the sale or other
disposition of property or assets of the Borrower or any of its Subsidiaries
that secure their respective Indebtedness.

<PAGE>
                 (i)     such Subsidiary simultaneously executes and delivers
         a guarantee (a "Subsidiary Guarantee") of payment of the Obligations;
         and

                 (ii)    such Subsidiary waives and will not in any manner
         whatsoever claim or take the benefit or advantage of, any rights of
         reimbursement, indemnity or subrogation or any other rights against the
         Borrower or any other Subsidiary as a result of any payment by such
         Subsidiary under its Subsidiary Guarantee until the Extensions of
         Credit have been paid in full, in U.S. dollars;

provided that this paragraph shall not be applicable to any Guarantee of any
Subsidiary that existed at the time such Person became a Subsidiary and was not
Incurred in connection with, or in contemplation of, such Person becoming a
Subsidiary.

         (b)     If the Guaranteed Indebtedness is (i) pari passu with the
Extensions of Credit, then the Guarantee of such Guaranteed Indebtedness shall
be pari passu with, or subordinated to, the Subsidiary Guarantee or (ii)
subordinated to the Extensions of Credit, then the Guarantee of such Guaranteed
Indebtedness shall be subordinated to the Subsidiary Guarantee at least to the
extent that the Guaranteed Indebtedness is subordinated to the Extensions of
Credit.

         (c)     Notwithstanding the foregoing, any Subsidiary Guarantee by a
Subsidiary shall provide by its terms that it shall be automatically and
unconditionally released and discharged upon:

         Agreement); or

                 (ii)    the release or discharge of the Guarantee which
         resulted in the creation of such Subsidiary Guarantee, except a
         discharge or release by or as a result of payment under such Guarantee.

5.0% or more of any class of Capital Stock of Grupo TFM or the Borrower or with
any Affiliate of Grupo TFM or the Borrower or any Subsidiary, except upon fair
and reasonable terms no less favorable to the Borrower or such Subsidiary than
could be obtained, at the time of such transaction or, if such transaction is
pursuant to a written agreement, at the time of the execution of the agreement
providing therefor, in a comparable arm's-length transaction with a Person that
is not such a holder or an Affiliate.

         (b)     The limitation of paragraph (a) of this Section 8.10 does not
limit, and shall not apply to:

                 (i)     transactions for which the Borrower or a Subsidiary
         delivers to the Administrative Agent a written opinion of a United
         States nationally recognized

         party; and

                 (vi)    other transactions in the aggregate in any calendar
         year involving consideration of no more than $2,000,000.

maturity, the proceeds of such drawing to be deposited in the Letter of Credit
Account, and require from the Borrower immediate reimbursement for payments
pursuant to such drawing; the Letter of Credit shall automatically terminate
fifteen days following the date of delivery of the Notice of Acceleration;

         (c)     if no Notice of Acceleration has been delivered pursuant to
paragraph (b) above, direct the Borrower immediately to pay into an account
specified by the Administrative Agent an amount in immediately available funds
(to which neither the Issuing Bank nor the Banks shall have any right in
respect of any drawing until the Issuing Bank shall have honored the same)
equal to the Stated Amount or, if less, the aggregate Face Amount of all CP
Notes outstanding whereupon such amount shall become immediately due and
payable by the Borrower without presentment, demand, protest or other notice,
all of which are hereby expressly waived;

         (d)     declare the principal amount of the Loans to be forthwith due
and payable, whereupon such principal amount, together with accrued interest
thereon and any fees and all other Obligations accrued hereunder, shall become
immediately due and payable, without

                                       76
<PAGE>
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived; provided, however, that in the case of any Event of
Default specified in paragraph (f) of Section 9.1, without notice or any other
act by the Banks, the Loans (together with accrued interest thereon) and all
other obligations of the Borrower hereunder shall become immediately due and
payable without presentment, demand, protest or other notice of any kind, all of
which are hereby waived by the Borrower; and/or

         (e)     notify the Borrower, the Depositary and each Dealer and each
(which notice may be by telephone to be confirmed in writing within two
Business Days) that an Event of Default has occurred and is continuing and in
such notice direct the Borrower and the Depositary not to issue any CP Notes
from and after the actual receipt by the Depositary of such notice until
receipt by the Depositary of a written Notice of Rescission of Default, in
substantially the form of Exhibit N, from the Administrative Agent (who shall
send a copy of such notice to the Borrower and the Issuing Bank) of such Event
of Default by reason of waiver or cure in accordance with the terms hereof;

provided, however, that nothing in this Section 9.2 shall (x) impair the
obligation of the Issuing Bank to make payments in accordance with the Letter of
Credit with respect to maturing CP Notes which have been validly issued and are
outstanding pursuant to the terms of this Agreement and the Depositary Agreement
or (y) impair the obligation of the Borrower to reimburse the Issuing Bank for,
or the obligation of any Bank to fund its participation in, any drawing made
subsequent to the time any remedy provided in this paragraph shall have been
exercised and, provided, further, that nothing in this Section 9.2 shall give
the Issuing Bank the right to request the Depositary to debit the Commercial
Paper Account on any Business Day until after such time as the Issuing Bank
shall have honored any demand for payment under the Letter of Credit required to
be paid on such Business Day.

                            THE ADMINISTRATIVE AGENT

         SECTION 10.1.     Appointment. Each Bank hereby irrevocably designates
and appoints JPMCB, as the Administrative Agent of such Bank under this
Agreement, and each such Bank hereby irrevocably authorizes JPMCB, as the
Administrative Agent for such Bank, to take such action on its behalf under the
provisions of this Agreement and to exercise such powers and perform such duties
as are expressly delegated to the Administrative Agent by the terms of this
Agreement, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or otherwise exist against the
Administrative Agent.

         SECTION 10.2.     Delegation of Duties. The Administrative Agent may
execute any of its duties under this Agreement by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties.

                                       77
<PAGE>
         SECTION 10.3.     Exculpatory Provisions. Neither the Administrative
Agent nor any of its officers, directors, employees, agents, attorneys-in-fact
or affiliates shall be (a) liable for any action lawfully taken or omitted to
be taken by it or any such Person under or in connection with this Agreement
(except for its or such Person's own gross negligence or willful misconduct),
or (b) responsible in any manner to any of the Banks for any recitals,
statements, representations or warranties made by the Borrower or any officer
thereof contained in this Agreement or in any certificate, report, statement or
other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, this Agreement or for the
value, validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement or any of the Principal Documents or for any failure of the
Borrower to perform its obligations hereunder or thereunder. Except in respect
of Section 5.1 or except as otherwise expressly stated herein, the
Administrative Agent shall not be under any obligation to any Bank to ascertain
or to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement, or to inspect the properties,
books or records of the Borrower.

         SECTION 10.4.     Reliance by the Administrative Agent. The
Administrative Agent shall be entitled to rely, and shall be fully protected in
relying, upon any agreement (including this Agreement), note (including any
Note), writing, resolution, notice, consent, certificate, affidavit, letter,
cablegram, telegram or teletype message, statement, order or other document or
facsimile transmission or telephone conversation reasonably believed by it to
be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including
counsel to the Borrower), independent accountants and other experts selected by
the Administrative Agent. The Administrative Agent may deem and treat the
payee of any Note as the owner thereof for all purposes unless a written notice
of assignment, negotiation or transfer thereof shall have been filed with the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement unless it shall
first receive such advice or concurrence of the Majority Banks as it deems
appropriate or it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Administrative Agent
shall in all cases be fully protected in acting, or in refraining from acting,
under this Agreement and the Notes in accordance with a request of the Majority
Banks, and such request and any action taken or failure to act pursuant thereto
shall be binding upon all the Banks and all future holders of the Notes.

         SECTION 10.5.     Notice of Default. The Administrative Agent shall
not be deemed to have knowledge or notice of the occurrence of any Default or
Event of Default hereunder unless the Administrative Agent has received notice
from a Bank, the Issuing Bank or the Borrower referring to this Agreement,
describing such Default or Event of Default. In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall
give prompt notice thereof to the Banks. The Administrative Agent shall take
such action with respect to such Default or Event of Default as shall be
directed by the Majority Banks; provided that, unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, in accordance with
the terms hereof, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interests of
the Banks.

                                       78
<PAGE>
         SECTION 10.6.     Non-Reliance on the Administrative Agent and Other
Banks. Each Bank expressly acknowledges that neither the Administrative Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates has made any representations or warranties to it and that no act by
the Administrative Agent hereinafter taken, including any review of the affairs
of the Borrower, shall be deemed to constitute any representation or warranty
by the Administrative Agent to any Bank. Each Bank represents to the
Administrative Agent that it has, independently and without reliance upon the
Administrative Agent or any other Bank, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Borrower and made its own decision to
make its loans hereunder and enter into this Agreement. Each Bank also
represents that it will, independently and without reliance upon the
Administrative Agent or any other Bank, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement, and to make such investigations as it deems necessary to inform
itself as to the business, operations, property, financial and other condition
and creditworthiness of the Borrower. Except for notices, reports and other
documents expressly required to be furnished by the Borrower to the
Administrative Agent hereunder, the Administrative Agent shall not have any
duty or responsibility to provide any Bank with any information concerning the
business, operations, property, financial and other condition or
creditworthiness of the Borrower which may come into the possession of the
Administrative Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or affiliates.

         SECTION 10.7.     Indemnification. The Banks agree to indemnify the
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to their respective Participation Fractions in effect on the
date on which indemnification is sought under this Section 10.7 (or, if
indemnification is sought after the date upon which all of the Commitments
shall have terminated and the Obligations shall have been paid in full, ratably
in accordance with their respective Participation Fractions immediately prior
to such termination), from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind whatsoever which may at any time (including at any
time following the payment of the Obligations or the Termination Date) be
imposed on, incurred by or asserted against the Administrative Agent in any way
relating to or arising out of this Agreement, or any documents contemplated by
or referred to herein or the transactions contemplated hereby or any action
taken or omitted by the Administrative Agent under or in connection with any of
the foregoing; provided, however, that such indemnity shall not, as to the
Administrative Agent, be available to the extent that such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements are determined by a court of competent jurisdiction
by final and non-appealable judgment to have resulted from the Administrative
Agent's gross negligence or willful misconduct. The Agreements in this Section
10.7 shall survive the payment of the Obligations and the Termination Date.

         SECTION 10.8.     The Administrative Agent in Its Individual Capacity.
JPMCB and its Affiliates may make loans to, accept deposits from and generally
engage in any kind of business with the Borrower as though JPMCB were not the
Administrative Agent hereunder. With respect to Loans made by it and any Note
issued to it, JPMCB shall have the same rights

                                       79
<PAGE>
and powers under this Agreement as any Bank and may exercise the same as though
it were not the Administrative Agent, and the terms "Bank" and "Banks" shall
include JPMCB and such Affiliates in their individual capacities.

         SECTION 10.9.     Successor Administrative Agent. The Administrative
Agent may be removed at any time upon the written request of all of the Banks
(not including the Administrative Agent or its Affiliates) and the written
consent of the Borrower and the Issuing Bank, such consent not to be
unreasonably withheld, delivered to the Administrative Agent, Issuing Bank, the
Borrower the Dealers and Depositary. The Administrative Agent may resign as
Administrative Agent upon 10 days' notice to the Banks and the Borrower. If
the Administrative Agent shall resign or be removed as Administrative Agent
under this Agreement, then the Majority Banks shall appoint from among the
Banks a successor agent for the Banks which successor agent shall be subject to
approval by the Borrower, whereupon such successor agent shall succeed to the
rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent effective upon its
appointment, and the former Administrative Agent's rights, powers and duties as
Administrative Agent shall be terminated, without any other or further act or
deed on the part of such former Administrative Agent or any of the parties to
this Agreement or any holders of the Notes. After any retiring Administrative
Agent's resignation or removal hereunder as Administrative Agent, the
provisions of this Article X shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Administrative Agent under this
Agreement. In the event the Administrative Agent resigns or is removed
pursuant to this Section 10.9, all fees paid to the resigning Administrative
Agent but not yet accrued shall be transferred to the successor Administrative
Agent.

                                   ARTICLE XI

                                THE ISSUING BANK

         SECTION 11.1.     Appointment. Each Bank hereby irrevocably designates
and appoints Standard Chartered Bank, as the Issuing Bank under this Agreement,
and each such Bank hereby irrevocably authorizes Standard Chartered Bank, as
the Issuing Bank to issue the Letter of Credit under and in accordance with
this Agreement, to pay the amount of any draft presented under the Letter of
Credit upon presentation of documents which, upon their face, conform to the
terms of the Letter of Credit, to receive from the Borrower reimbursement for
LOC Advances and to take such action on its behalf under the provisions of this
Agreement and the Depositary Agreement and to exercise such powers and to
perform such duties, hereunder as are specifically delegated to or required of
the Issuing Bank by the terms hereof and thereof, together with such powers as
are reasonably incidental thereto. Notwithstanding any provision to the
contrary elsewhere in this Agreement, the Issuing Bank shall not have any
duties or responsibilities, except those expressly set forth herein, or any
fiduciary relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or otherwise exist against the Issuing Bank; provided, however, that
nothing contained in this Article XI shall be deemed to limit or impair the
rights and obligations of the Issuing Bank hereunder or under the Letter of
Credit.

<PAGE>
         SECTION 11.2.     Exculpatory Provisions. Neither the Issuing Bank nor
any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement (except
for such Person's own gross negligence or willful misconduct), or (b)
responsible in any manner to any of the Banks for any recitals, statements,
representations or warranties made by the Borrower or any officer thereof
contained in this Agreement or in any certificate, report, statement or other
document referred to or provided for in, or received by the Issuing Bank under
or in connection with, this Agreement or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any of the Principal Documents or for any failure of the Borrower to perform
its obligations hereunder or thereunder. Except as otherwise expressly stated
herein, the Issuing Bank shall not be under any obligation to any Bank to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement, or to inspect the
properties, books or records of the Borrower.

         SECTION 11.3.     Reliance by Issuing Bank. The Issuing Bank shall be
entitled to rely, and shall be fully protected in relying, upon any agreement
(including this Agreement), note (including any Note), writing, resolution,
notice, consent, certificate, affidavit, letter, cablegram, telegram or
teletype message, statement, order or other document or facsimile transmission
or telephone conversation reasonably believed by it to be genuine and correct
and to have been signed, sent or made by the proper Person or Persons and upon
advice and statements of legal counsel (including counsel to the Borrower),
independent accountants and other experts selected by the Issuing Bank. Except
for the issuance of the Letter of Credit in accordance with the terms of this
Agreement and the payment of drawings thereunder, the Issuing Bank shall be
fully justified in failing or refusing to take any action under this Agreement
unless it shall first receive such advice or concurrence of the Majority Banks
as the Issuing Bank deems appropriate or it shall first be indemnified to its
satisfaction by the Banks against any and all liability and expense which may
be incurred by it by reason of failing to take, taking or continuing to take
any such action. The Issuing Bank shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement and the Notes in
accordance with a request of the Majority Banks, and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Banks and all future holders of the Notes.

         SECTION 11.4.     Indemnification. The Banks agree to indemnify the
Issuing Bank in its capacity as such (to the extent not reimbursed by the
Borrower and without limiting the obligation of the Borrower to do so), ratably
according to the respective amounts of their Participation Fractions in effect
on the day indemnification is sought under this Section 11.4 (or, if the
indemnification is sought after the date upon which the Commitments shall have
terminated and the Obligations shall have been paid in full, ratably in
accordance with their respective Participation Fractions immediately prior to
such termination), from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind whatsoever which may at any time (including at any
time following the payment of the Obligations or the Termination Date) be
imposed on, incurred by or asserted against the Issuing Bank in any way
relating to or arising out of this Agreement, or any documents contemplated by
or referred to herein or the transactions contemplated hereby or any action
taken or omitted by the Issuing Bank under or in connection with any of the
foregoing; provided, however, that such indemnity shall not, as to the Issuing
Bank, be available to the

                                       81
<PAGE>
extent that such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements are determined by a court of
competent jurisdiction by final and non-appealable judgment to have resulted
from (i) the Issuing Bank's gross negligence or willful misconduct, or (ii) any
untrue statement of a material fact in the material furnished in writing by the
Issuing Bank to the Borrower for inclusion in any CP Memorandum used in the
offer or sale of CP Notes or any omission in such material to state a material
fact required to be stated therein in light of the circumstances under which
they were made. Notwithstanding the foregoing, no Bank shall be required to
fund any other Bank's portion of an LOC Advance which such other Bank fails to
fund hereunder. The agreements in this Section 11.4 shall survive the payment
of the Obligations and the Termination Date.

         SECTION 11.5.     Issuing Bank in Its Individual Capacity. Standard
Chartered Bank and its affiliates may make loans to, accept deposits from and
generally engage in any kind of business with the Borrower as though Standard
Chartered Bank were not the Issuing Bank hereunder. With respect to Loans made
or renewed by Standard Chartered Bank and any Note issued to Standard Chartered
Bank, the Issuing Bank and its Affiliates shall have the same rights and powers
under this Agreement as any Bank and may exercise the same as though it were
not the Issuing Bank, and the terms "Bank" and "Banks" shall include Standard
Chartered Bank and such Affiliates in their individual capacities.

         SECTION 11.6.     Non-Reliance on Issuing Bank and Other Banks. Each
Bank expressly acknowledges that neither the Issuing Bank nor any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates has
made any representations or warranties to it and that no act by the Issuing
Bank hereinafter taken, including any review of the affairs of the Borrower,
shall be deemed to constitute any representation or warranty by the Issuing
Bank to any Bank. Each Bank represents to the Issuing Bank that it has,
independently and without reliance upon the Issuing Bank or any other Bank, and
based on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Borrower and made its
own decision to make its loans hereunder and enter into this Agreement. Each
Bank also represents that it will, independently and without reliance upon the
Issuing Bank or any other Bank, and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this

itself as to the business, operations, property, financial and other condition
and creditworthiness of the Borrower. Except for notices, reports and other
documents expressly required to be furnished by the Borrower to the Issuing
Bank hereunder, the Issuing Bank shall not have any duty or responsibility to
provide any Bank with any information concerning the business, operations,
property, financial and other condition or creditworthiness of the Borrower
which may come into the possession of the Issuing Bank or any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates.

                    THE JOINT LEAD ARRANGERS, ARRANGERS AND
                              DOCUMENTATION AGENT

         SECTION 12.1.     The Joint Lead Arrangers, etc. The Borrower hereby
confirms the appointment of and designates J.P. Morgan Securities Inc. and
Salomon Smith Barney Inc., as Joint Lead Arrangers, Bank of America, N.A.,
Comerica Bank, Landesbank Schlweswig-Holstein Girozentrale, Kiel and Standard
Chartered Bank, as Arrangers (the Joint Lead Arrangers and the Arrangers for
purposes of this Article XII, individually, an "Arranger" and collectively, the
"Arrangers") and Standard Chartered Bank, as Documentation Agent (the
Documentation Agent for purposes of this Article XII, the "Agent") under this
Agreement. The Arrangers and the Agent assume no responsibility or obligation
hereunder for servicing, enforcement or collection of the Obligations, or any
duties as agent for the Banks. The title "Joint Lead Arranger", "Arranger" or
"Documentation Agent" implies no fiduciary responsibility on the part of such
Arranger or Agent to the Issuing Bank or the Banks or any other party to this
Agreement and the use of such title does not impose on any Arranger or Agent
any duties or obligations under this Agreement except as may be expressly set
forth herein.

         SECTION 12.2.     Exculpatory Provisions. No Arranger or Agent nor any
of its respective officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by them under or in connection with this Agreement (except for its or for
such Person's own gross negligence or willful misconduct), or (b) responsible
in any manner to any of the Banks for any recitals, statements, representations
or warranties made by the Borrower or any officer thereof contained in this
Agreement or in any certificate, report, statement or other document referred
to or provided for in, or received by any Arranger or Agent under or in
connection with, this Agreement or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any of the
Principal Documents or for any failure of the Borrower to perform its
obligations hereunder or thereunder. Except as otherwise expressly stated
herein, no Arranger or Agent shall be under any obligation to any Bank to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement, or to inspect the
properties, books or records of the Borrower.

         SECTION 12.3.     Arrangers and Agent. Bank of America, N.A., Comerica
Bank, Landesbank Schlweswig-Holstein Girozentrale, Kiel and Standard Chartered
Bank and their respective affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Borrower as though Bank
of America, N.A., Comerica Bank, Landesbank Schlweswig-Holstein Girozentrale,
Kiel and Standard Chartered Bank were not an Arranger or Agent hereunder.

         SECTION 12.4.     Non-Reliance on the Arrangers, Agent and Other Banks.
Each Bank expressly acknowledges that no Arranger or Agent nor any of its
respective officers, directors, employees, agents, attorneys-in-fact or
affiliates has made any representations or warranties to it and that no act by
any Arranger or Agent hereinafter taken, including any review of the affairs of
the Borrower, shall be deemed to constitute any representation or warranty by
such Arranger or Agent to any Bank. Each Bank represents to the Arrangers and
the Agent that

                                       83
<PAGE>
it has, independently and without reliance upon any Arranger or Agent or any
other Bank, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Borrower and made its own decision to make its loans hereunder and enter into
this Agreement. Each Bank also represents that it will, independently and
without reliance upon any Arranger or Agent or any other Bank, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement, and to make such investigations as it
deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Borrower. No
Arranger or Agent shall have any duty or responsibility to provide any Bank
with any information concerning the business, operations, property, financial
and other condition or creditworthiness of the Borrower which may come into the
possession of such Arranger or Agent or any of its respective officers,
directors, employees, agents, attorneys-in-fact or affiliates.

                                  ARTICLE XIII

                                 MISCELLANEOUS

other out-of-pocket expenses and (ii) all reasonable fees and disbursements of
counsel for the Administrative Agent, the Joint Lead Arrangers, the Arrangers

         (b)     The Borrower further agrees, upon demand communicated through
the Administrative Agent, to reimburse and hold the Banks, the Issuing Bank,
the Administrative Agent, the Joint Lead Arrangers and the Arrangers harmless
from liability for the payment of all of their out-of-pocket costs and expenses
reasonably incurred by any of them and arising in connection with any Default

                 (ii)  reduce the principal amount of the Obligations, reduce

right consequent thereon.

         SECTION 13.5.     GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND
BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

         SECTION 13.6.     Indemnification.

         (a)     The Borrower agrees to indemnify the Issuing Bank, the
Administrative Agent, the Joint Lead Arrangers, the Arrangers, the Banks and
each Related Party of any of the foregoing Persons (each such Person being
called an "Indemnitee") from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind whatsoever, including, without limitation, all
reasonable fees, documented as to the scope of services provided, and
disbursements of counsel (including the allocated cost of internal counsel)
which may at any time (including at any time following the payment of the
Obligations or the Termination Date) be imposed on or incurred by any such
Indemnitee in connection with the investigation of, preparation for,
participation in or outcome of any pending or threatened claim or cause of
action relating to or arising out of this Agreement or any documents
contemplated by or referred to herein or the transactions contemplated hereby
or thereby or any action taken or omitted by such Indemnitee under or in
connection with any of the foregoing and which would not have been incurred by
or asserted or awarded against such indemnified party but for such Indemnitee
being involved with the Agreement or any documents

                                       86
<PAGE>
contemplated by or referred to herein or the transactions contemplated hereby
or any action taken or omitted by such Indemnitee in connection with any of the
foregoing; provided, however, that such indemnity shall not, as to any
Indemnitee, be available to the extent that such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements are determined by a court of competent jurisdiction by final and
non-appealable judgment to have resulted from (i) any untrue statement of a
material fact relating to such Indemnitee in any CP Memorandum used in the sale
of the CP Notes or any omission to state a material fact relating to such
Indemnitee therein necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading if such
information was approved in writing by such Indemnitee prior to its inclusion
in such CP Memorandum, or (ii) the gross negligence or willful misconduct of
such Indemnitee.

         (b)     This Section 13.6 shall survive the termination of this
Agreement and the payment of the Obligations.

         SECTION 13.7.     Notices.

         (a)     Except as otherwise expressly provided herein, all notices,
requests, demands or other communications to or upon the respective parties
hereunder shall be in writing, sent by courier or express mail service or by
facsimile transmission and, unless otherwise expressly provided herein, shall
be effective upon receipt by the party to whom such communications were sent,
or, in the case of notice by facsimile, upon confirmation by the sender of
receipt, addressed to such party, at its address shown in Schedule 1.1(b) (in
the case of the Banks) or below (in all other cases) or at such other address
as such party may hereafter notify to the other. Any communication with respect
to a change of address shall be deemed to be given or made when received by the
party to whom such communication was sent.

         (b)     Notices and other communications to the Banks hereunder may be
delivered or furnished by electronic communications pursuant to procedures
approved by the Administrative Agent and the Issuing Bank; provided that the
foregoing shall not apply to notices pursuant to Articles II, III and IV unless
otherwise agreed by the Administrative Agent, the Issuing Bank and the
applicable Bank. The Administrative Agent, the Issuing Bank or the Borrower
may, in its discretion, agree to accept notices and other communications to it
hereunder by electronic communications pursuant to procedures approved by it;
provided that approval of such procedures may be limited to particular notices
or communications.

         SECTION 13.8.     Table of Contents; Descriptive Headings; etc. The
table of contents and descriptive headings of the several sections of this
Agreement are inserted for convenience only and shall not be deemed to affect
the meaning or construction of any of the provisions hereof.

         SECTION 13.9.     Survival of Agreements and Representations. All
covenants, agreements, representations and warranties made herein, in the
Notes, or in any certificate delivered pursuant hereto or thereto shall survive
the execution and delivery hereof, the issuance of the Letter of Credit and the
Loans made hereunder.

         SECTION 13.10.    Benefit of Agreement; Assignment. This Agreement
shall be binding upon the Borrower, its successors and assigns, and shall inure
to the benefit of the Issuing Bank, the Joint Lead Arrangers, the Arrangers,
the Documentation Agent, the Administrative Agent and the Banks and their
respective successors and assigns except that (a) the Borrower may not transfer
or assign any or all of its rights or obligations hereunder except with the
unanimous consent of all the Banks; (b) an assignment by a Bank of its
Commitment, its Note and its Loans can only be made to a bank or financial
institution organized and licensed under the laws of Mexico or a financial
institution registered with the Hacienda; and (c) no Bank may assign its
Commitment, its Note and the Loans made by such Bank and no Bank may make or
cause to be made its Loans hereunder through any other Person, except pursuant
to an instrument of assignment in substantially the form of Exhibit I (an
"Assignment and Acceptance") and with the consent of the Administrative Agent,
the Issuing Bank and the Borrower (which consent (x) in each case shall not be
unreasonably withheld, (y) in the case of the Borrower, shall not be required
in the case of an assignment to a Person party to this Agreement or a branch,
agency or Subsidiary thereof (a "Bank Affiliate") or after the occurrence and
during the continuance of an Event of Default and (z) in the case of the
Administrative Agent and the Issuing Bank shall not be required in the case of
an assignment to a Bank Affiliate); provided, however, that (i) the Borrower
shall not be required to pay any further amounts pursuant to Sections 4.8, 4.10
and 4.11 than would have been required to be paid but for

                                       90
<PAGE>
the transfer of such Bank's interest to a Bank Affiliate or the making of Loans
through another office or Subsidiary of such Bank, except as provided in
Section 4.10, (ii) the Letter of Credit shall at all times be issued by the
Issuing Bank, (iii) any such assignment shall be in a minimum amount of
US$1,000,000 and (iv) the Assignee shall pay a fee of US$3,500 to the
Administrative Agent prior to the consummation of such assignment (other than
an assignment to a Bank Affiliate). Nothing herein shall prohibit any Bank
from pledging or assigning any Note to any Federal Reserve Bank in accordance
with applicable law and without compliance with the foregoing provisions of
this Section 13.10; provided, however, that such pledge or assignment shall not
release such Bank from its obligations hereunder.

         SECTION 13.11.    Participation. Notwithstanding the provisions of
Section 13.10, each Bank shall have the right from time to time to create and
sell one or more participations in its rights under this Agreement, its Note
and the Loans made by it to a bank or financial institution organized and
licensed under the laws of Mexico or a financial institution registered with
the Hacienda. Each Bank agrees to notify the Borrower as promptly as
practicable of the consummation of the sale of a participation in its rights
under this Agreement, its Note and the Loans made by it. No agreement or other
arrangement governing any such creation and sale (a "Participation Agreement")
shall confer upon the purchaser of such interest (a "Participant") any right to
contact, negotiate with or seek information from the Borrower under this
Agreement or such Bank's Note or to enforce this Agreement or such Bank's Note
against the Borrower directly, except as provided below. Any Participation
Agreement shall (a) prohibit the assignment or sale by the Participant of any
subparticipation interest and (b) permit the Bank to consent to waivers,
amendments, modifications or supplements of this Agreement without the consent
of the Participant, except in the case of waivers, amendments or modifications
extending the maturity of any Loan or Note in respect of which such
Participation was granted, or reducing the rate or extending the time for
payment of any installment of interest thereon or reducing the principal
thereof, or reducing the amount or basis of calculation of any Fees to accrue
in respect thereof. Notwithstanding the foregoing, any Participant shall be
entitled to the benefits of Sections 4.8, 4.10 and 4.11 pursuant to its
Participation Agreement as if such Participant were a Bank named herein,
provided, however, that the Borrower shall not be required to pay any further
amounts pursuant to such Sections than would have been required to be paid but
for the sale to such Participant of such Participant's participation interest.

         SECTION 13.12.    Right of Set-off. Upon the occurrence and during
the continuance of any Event of Default, the Administrative Agent, the Issuing
Bank and the Banks are hereby authorized at any time and from time to time,
without notice to the Borrower (any such notice being expressly waived by the
Borrower) and 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, in
any currency) at any time held and other indebtedness at any time owing by the
Administrative Agent, the Issuing Bank or the Banks to or for the credit or the
account of the Borrower against any and all of the obligations of the Borrower

HEREBY IRREVOCABLY DESIGNATES AS OF THE EFFECTIVE DATE CT CORPORATION SYSTEM

EFFECTIVE SERVICE UPON THE BORROWER AND THAT FAILURE OF ANY SUCH AGENT TO GIVE
ANY NOTICE OF SUCH SERVICE TO THE BORROWER SHALL NOT AFFECT THE VALIDITY OF
SUCH SERVICE OR ANY JUDGMENT RENDERED IN ANY ACTION OR PROCEEDING BASED
THEREON. EXCEPTING THE BORROWER, EACH OF THE PARTIES HERETO AGREES THAT
SERVICE OF ANY AND ALL SUCH PROCESS OR OTHER DOCUMENTS ON SUCH PERSON MAY ALSO
BE EFFECTED BY REGISTERED MAIL TO ITS ADDRESS AS SET FORTH IN SECTION 13.7 OR
SCHEDULE 1.1(b). WITH RESPECT TO THE BORROWER, SERVICE, OF ANY AND ALL SUCH
PROCESS OR OTHER DOCUMENTS TO CT CORPORATION OR SUCH OTHER AGENT FOR SERVICE OF
PROCESS DESIGNATED BY THE BORROWER IN ACCORDANCE WITH THIS AGREEMENT, SERVICE
OF PROCESS SHALL CONSTITUTE VALID AND EFFECTIVE SERVICE ONLY IF MADE IN PERSON.

         SECTION 13.14.    Judgment Currency. All payments made under this
Agreement and the Principal Documents shall be made in New York, New York to
such account as may be directed by the payee from time to time in United States
Dollars, and, if for any reason any payment made hereunder is made in a
currency (the "Other Currency") other than United States Dollars, then to the
extent that the payment actually received by the Banks, the Issuing Bank, the
Joint Lead Arrangers, the Arrangers, the Documentation Agent or the
Administrative Agent, when converted into United States Dollars at the Rate of
Exchange (as defined below) on the date of payment (or, if conversion on such
date is not practicable, as soon thereafter as it is practicable for the Banks,
the Issuing Bank, the Joint Lead Arrangers, the Arrangers, the Documentation
Agent or the Administrative Agent to purchase United States Dollars) falls
short of the amount due under the terms of this Agreement or any Principal
Document, the Borrower, shall, as a separate and independent obligation of the
Borrower, indemnify the Banks, the Issuing Bank, the Joint Lead Arrangers, the
Arrangers, the Documentation Agent and the Administrative Agent and hold the
Banks, the Issuing Bank, the Joint Lead Arrangers, the Arrangers, the
Documentation Agent and the Administrative Agent harmless against the amount of
such shortfall. As used in this Section 13.14, the term "Rate of Exchange"
means the rate at which the Banks, the Issuing Bank, the Joint Lead Arrangers,
the Arrangers, the Documentation Agent or the Administrative Agent are able on
the relevant date to purchase United States Dollars with the Other Currency and
shall include any premiums and costs of exchange payable in connection with the
purchase of or conversion into, United States Dollars.

         SECTION 13.15.    Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by the different parties hereto in
separate counterparts, each of which when so executed and delivered shall be
deemed to be an original and all of which taken together shall constitute one
and the same instrument.

         SECTION 13.16.    Waiver of Immunities. To the extent that the
Borrower has or hereafter may acquire any immunity from jurisdiction of any
court or from any legal process

                                       93
<PAGE>
(whether through service or notice, attachment prior to judgment, attachment in
aid of execution, execution or otherwise) with respect to itself or its
property, the Borrower hereby irrevocably waives such immunity in respect of
its obligations under this Agreement and the other Principal Documents. The
foregoing waiver is intended to be effective to the fullest extent now or
hereafter permitted by applicable law.

         SECTION 13.17.    Severability. To the fullest extent permitted by
law, any provision of this Agreement which is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
provisions hereof or affecting the validity or enforceability of such provision
in any other jurisdiction, and the remaining portion of such provision and all
other remaining provisions hereof will be construed to render them enforceable.

         SECTION 13.18.    Confidentiality. Each of the Issuing Bank, the Joint
Lead Arrangers, the Arrangers, the Documentation Agent, the Administrative
Agent and each of the Banks agrees that it will not disclose without the prior
consent of the Borrower (other than to its affiliates, employees, auditors or
counsel or to another Bank) any information with respect to the Borrower which
is furnished pursuant to this Agreement or any other Principal Document except
that any such Person may disclose any such information (a) as has become
generally available to the public other than by a breach by such Person of this
Section 13.18, (b) as may be requested or required by any Governmental
Authority having or claiming to have jurisdiction over such Person (provided
that such Person does not object to such body's claim of jurisdiction over it)
or to the Federal Reserve Board or the Federal Deposit Insurance Corporation or
similar organizations (whether in the United States or elsewhere) or their
successors, (c) as may be required in response to any summons or subpoena or
any law, order, governmental direction, regulation or ruling applicable to such
Person, or (d) to any prospective participant or assignee in connection with
any contemplated transfer pursuant to Section 13.10 or Section 13.11, provided
that such prospective transferee shall have been made aware of this Section
13.18 and shall have agreed to be bound by its provisions as if it were a party
to this Agreement. Notwithstanding the foregoing, the Administrative Agent may
make any such information available to the Depositary.

         SECTION 13.19.    No Waiver; Remedies. No failure on the part of the
Administrative Agent, the Issuing Bank, the Joint Lead Arrangers, any Arranger,
the Documentation Agent or any of the Banks to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall
any single or partial exercise of any right hereunder preclude any other or
further exercise thereof or the exercise of any other right. The remedies
herein provided are cumulative and not exclusive of any remedies provided by
law.

         SECTION 13.20.    Prior Agreements Superseded. As of the Effective
Date, this Agreement shall completely and fully supersede all prior
undertakings or agreements, both written and oral, between or among the
Borrower, the Joint Lead Arrangers, the Arrangers, the Documentation Agent, the
Administrative Agent, the Issuing Bank, and/or the Banks, relating to the
issuance of the Letter of Credit by the Issuing Bank and the acquisition by the
Banks of their Commitments, including, but not limited to, those contained in
any mandate letter between the Borrower and the Joint Lead Arrangers executed
in anticipation of the issuance of the Letter of Credit by the Issuing Bank and
the acquisition by the Banks of their Commitments but excluding the Fee Letters
referred to herein.

         payment amount specified in such notice shall be due and payable on
         the date specified therein, together with accrued interest to, and
         any other amounts then due on, each such date on the amount prepaid.
         Prepayments of the Term Loans shall be in a minimum amount equal to
         US$5,000,000 and in multiples of US$1,000,000 in excess thereof, or,
         if less, the aggregate principal amount of the Term Loans then
         outstanding. Amounts prepaid may not be reborrowed.

         (b)      Mandatory Prepayments.

                  (i)     If on any date the Borrower or any its Subsidiaries
         shall receive Net Cash Proceeds from any Asset Sale permitted under
         Section 6.10 or from any issuance of Capital Stock under Section
         6.5(d), then, unless a Reinvestment Notice shall be delivered in
         respect thereof, such Net Cash Proceeds shall be applied in
         accordance with clause (ii) of this Section 2.4(b), on such date
         toward the prepayment of the Term Loans; provided, that,
         notwithstanding the foregoing, (i) aggregate Net Cash Proceeds of
         Asset Sales and issuances of Capital Stock of Subsidiaries not to
         exceed $10,000,000 in any fiscal year of the Borrower or $20,000,000
         prior to the Maturity Date shall be excluded and (ii) on each
         Reinvestment Prepayment Date, an amount equal to the Reinvestment
         Prepayment Amount with respect to the relevant Reinvestment Event
         shall be applied in accordance with clause (ii) of this Section
         2.4(b), toward the prepayment of the Term Loans until such
         outstanding Term Loans are repaid in full.

                  (ii)    Amounts to be applied in connection with prepayments
         made pursuant to clause (i) of this Section 2.4(b) shall be applied
         to the Term Loans.  Prepayments of the Term Loans shall be made
         ratably among the Banks based on the Commitment Percentages and shall
         be applied to installments thereof in the inverse order of maturity.

                  (iii)   Each prepayment of the Term Loans under this
         Section 2.4(b) shall be accompanied by accrued interest to the date
         of such prepayment on the amount prepaid. Any prepayment of the Term
         Loans pursuant to this Section shall be subject to the provisions of
         Section 2.14. Amounts prepaid may not be reborrowed.

         SECTION 2.5.      Interest Rates and Payment Dates.

                                      -22-

<PAGE>

         (a)      The Term Loans comprising each Tranche shall bear interest for
each day during the Interest Period for such Tranche on the unpaid principal
amount thereof at a rate per annum equal to LIBOR determined for such Interest
Period plus the Applicable Margin.

         (b)      If all or a portion of (i) the principal amount of the Term
Loans, (ii) any interest payable on the principal amount of the Term Loans or
(iii) any fee or other amount payable hereunder shall not be paid when due
(whether at the stated maturity, by acceleration or otherwise), such overdue
amount shall bear interest at a rate per annum equal to LIBOR plus the
Applicable Margin plus 2.0% from the date of such non-payment until paid in full
(both after and before judgment) and shall be payable on demand.

         (c)      Except as otherwise provided in paragraph (b) of this Section
2.5, interest shall be payable in arrears on each Interest Payment Date and on
the Maturity Date.

         SECTION 2.6.      Computation of Interest.

         (a)      Interest in respect of the Term Loans shall be calculated on
the basis of a 360 day year for the actual days elapsed. The Administrative
Agent shall, as soon as practicable, notify the Borrower and the Banks of each
determination of LIBOR; provided, however, that any failure to do so shall not
relieve the Borrower of any liability hereunder.

         (b)      Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Banks in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower or any Bank, deliver
to the Borrower or such Bank, as the case may be, a statement showing the
quotations used by the Administrative Agent in determining any interest rate
pursuant to Section 2.5(a).

         SECTION 2.7.      Inability to Determine Interest Rate. In the event
that the Administrative Agent shall have reasonably determined (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the interbank eurodollar market, adequate means do
not exist for ascertaining LIBOR applicable pursuant to Section 2.5(a) for any
requested Interest Period, the Administrative Agent shall forthwith give notice
by facsimile of such determination to the Borrower and each Bank at least one
day prior to the last day of the current Interest Period. During the 30 days
following such notice, the Borrower and the Administrative Agent shall negotiate
a mutually satisfactory interest rate to be substituted for the interest rate
calculated in accordance with Section 2.5(a). If a substituted interest rate is
agreed upon, it shall be effective from the first day of such Interest Period.
If the Borrower and the Administrative Agent fail to agree upon a substituted
interest rate, the unpaid principal amount of the Term Loans shall bear interest
from the first day of such Interest Period at the rate per annum equal to the
rate determined by the Required Lenders to be the cost to maintain such unpaid
principal amount outstanding during such period plus the Applicable Margin.

         SECTION 2.8.     Maximum Interest Rate. Anything in this Agreement or
any Notes to the contrary notwithstanding, the interest rate on the Term Loans
shall in no event be in excess of the maximum permitted by applicable law.

                                      -23-

<PAGE>

         SECTION 2.9.      Fees.

         (a)      Administration Fee. The Borrower will pay to the
Administrative Agent, for the sole account of the Administrative Agent, an
administration fee (the "Administration Fees") in the amount and at the times
agreed to by the Administrative Agent and the Borrower in a separate fee letter
(the "Administration Fee Letter").

         (b)      Arrangement Fees. The Borrower will pay to the Joint Lead
Arrangers, for the account of the Joint Lead Arrangers, the arrangement fees
(the "Arrangement Fees") in the amounts and at the times agreed to by the Joint
Lead Arrangers and the Borrower in a separate fee letter (the "Arrangement Fee
Letter").

         (c)      Up-Front Fees. The Borrower will pay to the Administrative
Agent, for the account of the Banks, an up-front fee (collectively, the
"Up-Front Fees") payable in accordance with the terms outlined on page 36 of the
TFM Lenders Meeting Presentation dated July 31, 2002.

         SECTION 2.10.     Pro Rata Treatment and Payments.

         (a)      The Term Loans shall be made by the Banks pro rata according
to their respective Commitments.

         (b)      Except as otherwise provided in Sections 2.11, 2.12, 2.13
and/or 2.14, each payment (including each prepayment) by the Borrower on account
of principal of and interest on the Term Loans shall be made pro rata according
to the respective outstanding principal amounts of the Term Loans held by each
Bank. All payments (including prepayments) to be made by the Borrower on account
of principal, interest, Fees and other amounts due and payable hereunder shall
be made without set-off or counterclaim and (except as otherwise provided in
Sections 2.13, 2.14, 2.15 and 2.16) shall be made prior to 12:00 Noon, New York
City time, on the due date thereof to the Administrative Agent, for the account
of the Banks, at the Administrative Agent's office set forth in Section 10.7,
which shall be maintained in New York, New York, in Dollars and in immediately
available funds. The Administrative Agent shall distribute such payments to the
Banks promptly upon receipt in like funds as received. The Borrower shall have
no liability to any Bank with respect to any amount for which the Borrower has
made payment to the Administrative Agent, for the account of such Bank. If any
payment on a Term Loan becomes due and payable on a day other than a Business
Day, the maturity thereof shall be extended to the next succeeding Business Day
unless the result of such extension would be to extend such payment into another
calendar month, in which event such payment shall be made on the immediately
preceding Business Day. In the case of any extension of any payment of principal
pursuant to the preceding sentence, interest thereon shall be payable at the
then applicable rate during such extension.

         (c)      Unless the Administrative Agent shall have been notified in
writing by any Bank prior to a borrowing that such Bank will not make the amount
that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Bank is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower a

                                      -24-

<PAGE>

corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Disbursement Date, such Bank shall pay to the
Administrative Agent, on demand, such amount with interest thereon, at a rate
equal to the greater of (i) the Federal Funds Effective Rate and (ii) a rate
determined by the Administrative Agent in accordance with banking industry rules
on interbank compensation, for the period until such Bank makes such amount
immediately available to the Administrative Agent. A certificate of the
Administrative Agent submitted to any Bank with respect to any amounts owing
under this paragraph shall be conclusive in the absence of manifest error. If
such Bank's share of such borrowing is not made available to the Administrative
Agent by such Bank within three Business Days after such Disbursement Date, the
Administrative Agent shall also be entitled to recover such amount with interest
thereon at the rate per annum applicable to the Term Loans, on demand, from the
Borrower.

         (d)      Unless the Administrative Agent shall have been notified in
writing by the Borrower prior to the date of any payment due to be made by the
Borrower hereunder that the Borrower will not make such payment to the
Administrative Agent, the Administrative Agent may assume that the Borrower is
making such payment, and the Administrative Agent may, but shall not be required
to, in reliance upon such assumption, make available to the Banks their
respective pro rata shares of a corresponding amount. If such payment is not
made to the Administrative Agent by the Borrower within three Business Days
after such due date, the Administrative Agent shall be entitled to recover, on
demand, from each Bank to which any amount which was made available pursuant to
the preceding sentence, such amount with interest thereon at the rate per annum
equal to the daily average Federal Funds Effective Rate. Nothing herein shall be
deemed to limit the rights of the Administrative Agent or any Bank against the
Borrower.

         SECTION 2.11.     Taxes.

         (a)      All payments made by the Borrower under this Agreement and any
Notes shall be made free and clear of, and without deduction for or on account
of, any present or future income, stamp, sales or other taxes, levies, imposts,
duties, charges, fees, deductions or withholdings, imposed, levied, collected,
withheld or assessed by any Governmental Authority of Mexico or any other
jurisdiction from which payment is made or is deemed to be made (excluding the
following "Excluded Taxes": net income taxes or franchise taxes imposed on any
recipient of such payment (each a "Payee") as a result of a present or former
connection between the jurisdiction of the Governmental Authority imposing such
tax and the Payee (other than any such connection arising solely from the Payee
having executed, delivered or performed its obligations or received a payment
under, or enforced, this Agreement) and withholding taxes to the extent imposed
by reason of any Payee or its assignees or participants, if any, failing to make
reasonable commercial efforts to maintain its registration with Hacienda). If
any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions
or withholdings ("Non-Excluded Taxes") are required to be withheld from any
amounts payable to any Payee hereunder, (subject to the right of the Borrower to
contest any such requirement in good faith, so long as proper reserves are
maintained and each Payee hereunder is paid the full amounts payable hereunder
including any gross-up payable) the Borrower shall pay such Non-Excluded Taxes
to the appropriate taxing authority, and the amounts payable to each such Payee
shall be increased by such additional amounts (the "Additional Amounts")
necessary to yield to such

                                      -25-

<PAGE>

Payee (after payment of all Non-Excluded Taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement. Whenever any Non-Excluded Tax is payable by the Borrower, as promptly
as possible thereafter, the Borrower shall send to the Administrative Agent, for
the account of such Payee, a certified copy by a Responsible Officer of the
Borrower of a stamped filed receipt showing payment thereof. If the Borrower
fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority
or fails to remit to the Administrative Agent the required receipts or other
required documentary evidence, the Borrower shall indemnify the affected Payees
for any incremental taxes, interest or penalties that may become payable by any
such Payee as a result of any such failure. This indemnity and agreement shall
survive termination of the Agreement and payment of the Term Loans.

         (b)     Each Payee shall, from time to time at the request of the
Borrower or the Administrative Agent, furnish to the Borrower or the
Administrative Agent, as the case may be, such documentation as may be required
to establish any available exemption from, or reduction in the amount of,
otherwise applicable Non-Excluded Taxes. The Borrower and the Administrative
Agent shall be entitled to rely upon the accuracy of any such documentation
furnished to it by any Payee and shall have no obligation to indemnify such
Payee for any incremental taxes, interest or penalties that may become payable
by such Payee solely as a result of any inaccuracy contained therein or the
Payee's failure to furnish such documentation.

         SECTION 2.12.     Illegality. Notwithstanding any other provisions
herein, if any Requirement of Law or any change therein or in the interpretation
or application thereof shall make it unlawful for any Bank to make or maintain a
Term Loan as contemplated by this Agreement, then such Bank may give notice
thereof to each of the Borrower and the Administrative Agent and, upon the
giving of such notice (a) the Commitment of such Bank hereunder to make a Term
Loan shall forthwith be canceled and (b) such Bank's Term Loans then outstanding
shall bear interest, from the last day of the then current Interest Period or
earlier if required by law, at the Base Rate plus the Applicable Margin then in
effect less 1.0% per annum. If any such conversion of Term Loans is made on a
day which is not the last day of the Interest Period therefor, the Borrower
shall pay to such Bank such amounts, if any, as may be required pursuant to
Section 2.14. For purposes of this Section 2.12, "Base Rate" shall mean, for any
day, the higher of (i) the rate of interest publicly announced by JPMCB from
time to time as its prime rate in New York City, the prime rate to change as and
when such designated rate changes or (ii) the effective Federal Funds Effective
Rate plus one-half of one percent (1/2 of 1.0%), in each case as in effect for
such day.

         SECTION 2.13.     Requirements of Law.

         (a)     If, after the Effective Date, and as a result of the adoption
of any law, regulation, treaty or official directive or request (whether or not
having the force of law) or any change therein or any introduction thereof
(which such change or introduction is publicly announced through official
governmental, regulatory or other customary means after the Effective Date) or
compliance therewith by the Borrower, the Administrative Agent or any Bank (or
any corporation controlling such Bank) including those relating to taxation,
reserves, special deposit, cash ratio, liquidity, capital adequacy or
Eurocurrency Liabilities or other requirement or

                                      -26-

<PAGE>

any other form of banking or monetary requirements or controls, any of the
following shall occur:

                  (i)      the cost to any Bank of maintaining its Term Loan is
         increased by an amount determined by such Bank to be material; or

                  (ii)     any amount receivable by any Bank is reduced by an
         amount determined by such Bank to be material as a result of
         maintaining its Term Loan; or

                  (iii)    the rate of return on such Bank's (or its controlling
         corporation's) capital is reduced as a consequence of its obligations
         hereunder below that which such Bank could have achieved but for such
         adoption, change or introduction (taking into consideration such
         Bank's or such corporation's policies with respect to capital
         adequacy) by an amount deemed by such Bank to be material;

in the case of each of clauses (i), (ii) and (iii) other than any increase in or
incurrence of cost, reduction in yield or other return or additional payment
resulting from Excluded Taxes, then and in each such case:

              (A) such Bank or the Administrative Agent on its own behalf
     (each of the foregoing, an "Affected Bank") shall notify the Borrower
     through the Administrative Agent in writing of such event promptly upon
     its becoming aware of the event entitling it to make a claim; and

              (B) upon demand from time to time by such Affected Bank through
     the Administrative Agent, the Borrower shall pay to the Administrative
     Agent for the account of such Affected Bank such amount as shall
     compensate such Affected Bank for such increased cost, reduced amount
     receivable or reduction in rate of return. The certificate of such
     Affected Bank specifying the amount of such compensation shall be
     conclusive save in the case of manifest error.

         (b)      If an Affected Bank shall request compensation under this
Section 2.13, such Bank shall furnish to the Borrower a statement setting forth
the basis for requesting such compensation.

         (c)      The covenants and agreements set forth in this Section 2.13
shall survive the termination of this Agreement and the payment of the
outstanding Term Loans. Failure or delay on the part of any Bank to demand
compensation pursuant to this Section 2.13 shall not constitute a waiver of such
Bank's right to demand compensation; provided that the Borrower shall not be
required to compensate a Bank, as applicable, pursuant to this Section 2.13 for
any increased costs or reductions incurred more than 180 days prior to the date
that such Bank notifies the Borrower of the event giving rise to such increased
costs or reductions and of such Bank's intention to claim compensation therefor;
and provided further that, if the event giving rise to such increased costs or
reduction is retroactive, then the 180 day period referred to above shall be
extended to include the period of retroactive effect thereof.

                                      -27-

<PAGE>

         SECTION 2.14.     Funding Indemnity. The Borrower agrees to indemnify
each Bank and to hold such Bank harmless from any actual loss or expense
(excluding loss of profit) which such Bank may sustain or incur as a consequence
of (a) default by the Borrower in payment when due (by acceleration or
otherwise) of the principal amount of or interest on the Term Loan of such Bank,
(b) default by the Borrower in making a borrowing of Term Loans or any
prepayment after the Borrower has given a notice in accordance with Section 2.2
or 2.4(a), respectively, and (c) the making by the Borrower of a prepayment of
the Term Loans on a day which is not the last day of the Interest Period with
respect thereto (whether or not the Administrative Agent or such Bank has
previously consented to such prepayment), including any such loss or expense
arising from interest or fees payable by such Bank to lenders of funds obtained
by it in order to maintain its Term Loan hereunder as set forth in a certificate
of such Bank delivered to the Borrower through the Administrative Agent. This
covenant shall survive termination of this Agreement and payment of the Term
Loans.

         SECTION 2.15.     Sharing of Payments, Etc.

         (a)     If, other than as expressly provided elsewhere herein, any
Bank shall obtain on account of the Obligations owing to it hereunder or in
respect of its Term Loan any payment (whether voluntary, involuntary, through
the exercise of any right of set-off, or otherwise) in excess of its Commitment
Percentage of payments on account of the Obligations obtained by all the Banks,
such Bank shall forthwith (i) notify the Administrative Agent of such fact, and
(ii) purchase from the other Banks such participations in such amounts made by
them as shall be necessary to cause such purchasing Bank to share the excess
payment ratably with each of them; provided, however, that if all or any portion
of such excess payment is thereafter recovered from the purchasing Bank, such
purchase shall to that extent be rescinded and each other Bank shall repay to
the purchasing Bank the purchase price paid therefor, together with an amount
equal to such paying Bank's Commitment Percentage (determined for this purpose
according to the proportion of (A) the amount of such paying Bank's required
repayment to (B) the total amount so recovered from the purchasing Bank) of any
interest or other amount paid or payable by the purchasing Bank in respect of
the total amount so recovered. The Administrative Agent will keep records (which
shall be conclusive and binding in the absence of manifest error) of
participations purchased pursuant to this Section 2.15 and will in each case
notify the Banks and the Borrower following any such purchases.

         (b)     The Borrower agrees that any Bank so purchasing a participation
from another Bank pursuant to this Section 2.15 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off, but subject to Section 10.12) with respect to such participation as
fully as if such Bank were the direct creditor of the Borrower in the amount of
such participation.

         SECTION 2.16.     Change of Lending Office.

         (a)     Each Bank agrees that, upon the occurrence of any event giving
rise to the operation of Section 2.11, 2.12 or 2.13(a) as to it, it will use its
reasonable best efforts to avoid or minimize the consequences of such event;
provided, however, that such action shall not, in the judgment of such Bank, as
the case may be, be illegal or economically or otherwise disadvantageous to it.
If such Bank is entitled to compensation for the events specified under

                                      -28-

<PAGE>

Section 2.11 or 2.13(a), or is required to make a prepayment as a
result of the operation of Section 2.12, it shall endeavor for a period of 30
days to designate a different office for any Obligation affected by such event
if such designation will avoid the need for, or reduce the amount of, such
compensation and will not, in the sole opinion of such Bank, result in any
economic, legal or regulatory or other disadvantage to such Bank or any of its
affiliates.

         SECTION 2.17.     Replacement of Banks. The Borrower shall be permitted
to replace any Bank that (a) requests reimbursement for amounts owing pursuant
to Section 2.11 or 2.13(a), (b) is required to make a prepayment as a result of
the operation of Section 2.12 or (c) defaults in its obligation to make its Term
Loan hereunder, with a replacement financial institution; provided that (i) such
replacement does not conflict with any Requirement of Law, (ii) no Event of
Default shall have occurred and be continuing at the time of such replacement,
(iii) prior to any such replacement, such Bank shall have taken no action under
Section 2.16 so as to eliminate the continued need for payment of amounts owing
pursuant to Section 2.11 or 2.13(a) or the operation of Section 2.12, (iv) the
replacement financial institution shall purchase, at par, the Term Loan and
other amounts owing to such replaced Bank on or prior to the date of
replacement, (v) the Borrower shall be liable to such replaced Bank under
Section 2.12 if the Term Loan owing to such replaced Bank shall be purchased
other than on the last day of an Interest Period relating thereto, (vi) the
replacement financial institution, if not already a Bank, shall be reasonably
satisfactory to the Administrative Agent, (vii) the replaced Bank shall be
obligated to make such replacement in accordance with the provisions of Section
10.10 (provided that the Borrower shall be obligated to pay the registration and
processing fee referred to therein), (viii) until such time as such replacement
shall be consummated, the Borrower shall pay all additional amounts (if any)
required pursuant to Section 2.11 or 2.13(a), as the case may be, and (ix) any
such replacement shall not be deemed to be a waiver of any rights that the
Borrower, the Administrative Agent or any other Bank shall have against the
replaced Bank.

                                  ARTICLE III

         SECTION 4.3.      Compliance with Law and Other Instruments.  Neither
the execution, delivery or performance of this Agreement or the Notes in
accordance with their respective terms, nor the consummation of the transactions

obligation to create or impose) any Lien upon any of the property or assets of
the Borrower pursuant to the terms of any indenture, mortgage, deed of trust,
agreement or other instrument (other than those permitted or required by this
Agreement and the Notes, including, without limitation, Permitted Liens) to
which the Borrower is a party or

actions, suits or proceedings pending or, to the best of the Borrower's
knowledge, threatened against or affecting the Borrower before any court,
tribunal or other Governmental Authority: (a) with respect to this Agreement,
the Notes or the transactions contemplated hereby or thereby or (b) which

required under any Environmental Law, (ii) has not become subject to any
Environmental Liability, (iii) has not received notice of any claim with respect

<PAGE>

         SECTION 4.7.      Taxes, Assessments and Fees. The Borrower has paid
all taxes due except such taxes as are being contested in good faith for which
adequate (in the good faith judgment of the Borrower) reserves have been made

reasonably be expected to have a Material Adverse Effect.

         SECTION 4.8.      Investment Company Act. The Borrower is not an
"investment company" required to be registered under the Investment Company Act
of 1940, as amended.

         SECTION 4.9.      Accuracy of Information. All written
information supplied by the Borrower to the Administrative Agent, the
Documentation Agent, the Joint Lead Arrangers, the Arrangers and the Banks
relating to the Borrower, viewed in the aggregate, was true and accurate in all

circumstances under which such information was supplied, not misleading.

has occurred and is continuing.

         SECTION 4.11.     Obligations Pari Passu; Recourse; Liens. The
Obligations of the Borrower under this Agreement and the Notes rank at least
pari passu in right of payment with all its other senior unsecured Indebtedness,
except for obligations accorded preference by mandatory provisions of law. There
is no Lien upon or with respect to any of the present or future properties or
Indebtedness of the Borrower or its Subsidiaries other than liens permitted or
required by this Agreement or the Notes, including, without limitation,
Permitted Liens.

         SECTION 4.12.     Withholding Tax. As of the Effective Date,
there is no tax, levy, impost, deduction, charge or withholding imposed, levied
or made by or in Mexico or any political subdivision or taxing authority thereof
or therein either (i) on or by virtue of the execution or delivery of this
Agreement or the Notes or the Fee Letters or (ii) on any payment to be made by
the Borrower pursuant to this Agreement or the Notes or any of the Fee Letters
to any Person, except that payments of interest under this Agreement and fees
payable hereunder and under any Fee Letter will be subject to a Mexican
withholding tax at a rate of 4.9% so long as the payee is a commercial bank or
other financial institution registered with Hacienda and, if applicable, the
Borrower complies with general rules issued by Hacienda. As of the Effective
Date, the Borrower is permitted under applicable law, to make all payments
pursuant to this Agreement, the Notes or the Fee Letters free and clear of all
taxes, levies, imposts, deductions, charges or withholdings imposed, levied or
made by or in Mexico or any political subdivision or taxing authority thereof,
as provided in this Agreement or in the Notes, without any liability to be borne
by the payee in connection with such Mexican withholding tax to the extent that
the Borrower has complied with its obligations in Section 2.11 of this Agreement
to pay to the appropriate Mexican authorities applicable withholding taxes
required to be paid by the Borrower.

         SECTION 4.13.     Proper Form; No Filing. This Agreement is (or, in the
case of any Note, will be, upon the issuance thereof in accordance herewith) in
proper legal form for the enforcement thereof in Mexico against the Borrower;
provided, however, that if any legal

                                      -34-

<PAGE>

proceedings are brought in a court of Mexico for the enforcement against the
Borrower, of this Agreement and the Notes, a Spanish translation of such
documents prepared by a translator approved by the Mexican court would have to
be approved by such court after the Borrower has been given the opportunity to
be heard with respect to the accuracy of the translation, and proceedings would
thereafter be based on the translated documents. To ensure the legality,
validity, enforceability or admissibility in evidence of this Agreement and the
Notes in Mexico it is not necessary that this Agreement or any other document be
filed or recorded with any Governmental Authority in Mexico or be notarized, or
that any stamp or similar tax be paid on or in respect of this Agreement or any
of the Notes.

         SECTION 4.14.     Choice of Law. In any action or proceeding involving
the Borrower arising out of or relating to this Agreement in any court of
Mexico, a Bank, the Joint Lead Arrangers, the Arrangers, the Documentation Agent
and the Administrative Agent would be entitled to the recognition and
effectiveness of the choice of law provisions of Section 10.5.

         SECTION 4.15.     Immunity. The Borrower is subject to suit in Mexico
and neither it nor its property has any right of immunity, on the grounds of
sovereignty or otherwise, from any legal action, suit or proceeding, set-off or
counterclaim, the jurisdiction of any competent court and service of process,
attachment or execution in Mexico with respect to its obligations, liabilities,
or any other matter under or arising out of or in connection with this Agreement
or any Notes, and to the extent that the Borrower or its property may have or
may hereafter become entitled to any such right of immunity it has effectively
waived such right under Section 10.16; provided, that the Concession Title may
not be transferred to any Person without the prior consent of Mexico.  The
waiver by the Borrower described in the immediately preceding sentence is a
legal, valid and binding obligation thereof.  The foregoing waiver is intended
to be effective to the fullest extent now or hereafter permitted by the
applicable law of any jurisdiction in which any suit, action or proceeding with
respect to this Agreement may be commenced. The performance of this Agreement
and the Notes by the Borrower constitutes private and commercial acts rather
than governmental or public acts.

         SECTION 4.16.     Status of Concession. The Concession Title is in
full force and effect and no investigation or proceeding seeking the termination
or revocation of the Concession Title has been initiated or attempted.

         SECTION 4.17.     Properties. (a) The Borrower has good title to, or
valid leasehold interests in, all its real and personal property material to its
business, except for minor defects in title that do not interfere with its
ability to conduct its business as currently conducted or to utilize such
properties for their intended purposes.

         (b)     The Borrower owns, or is licensed to use, all trademarks,
tradenames, copyrights, patents and other intellectual property material to its
business, and the use thereof by the Borrower does not infringe upon the rights

the aggregate, could not reasonably be expected to result in a Material Adverse
Effect.

         SECTION 4.18.     Subsidiaries. The Subsidiaries listed on Schedule
4.18 hereto constitute the only Subsidiaries of the Borrower as at the date
hereof.

         SECTION 4.19.     Federal Regulations. No part of the proceeds of any
Term Loan will be used for "buying" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U as now and
from time to time hereafter in effect or for any purpose that violates the
provisions of the Regulations of the Board.  If requested by any Bank or the
Administrative Agent, the Borrower will furnish to the Administrative Agent and
each Bank a statement to the foregoing effect in conformity with the
requirements of FR Form G-3 or FR Form U-1, as applicable, referred to in
Regulation U.

         SECTION 4.20.     Labor Matters. Except as, in the aggregate, could

employees of the Borrower have not been in violation of any applicable

accrued as a liability on the financial statements of the Borrower.

                  the property or assets of the Borrower or any of its
                  Subsidiaries in any manner material to the Borrower or to

provided that this paragraph shall not be applicable to any Guarantee of any
Subsidiary that existed at the time such Person became a Subsidiary and was not
Incurred in connection with, or in contemplation of, such Person becoming a
Subsidiary.

Loans, then the Guarantee of such Guaranteed Indebtedness shall be pari passu
with, or subordinated to, the Subsidiary Guarantee or (ii) subordinated to the
Term Loans, then the Guarantee of such Guaranteed Indebtedness shall be
subordinated to the Subsidiary Guarantee at least to the extent that the
Guaranteed Indebtedness is subordinated to the Term Loans.

         (c)      Notwithstanding the foregoing, any Subsidiary Guarantee by a
Subsidiary shall provide by its terms that it shall be automatically and
unconditionally released and discharged upon:

                  (i)      any sale, exchange or transfer, to any Person not an
          Affiliate of the Borrower, of all of the Borrower's or any
          Subsidiary's Capital Stock in, or all or substantially all the assets

          prohibited by this Agreement); or

                  (ii)     the release or discharge of the Guarantee which

transaction is pursuant to a written agreement, at the time of the execution of
the agreement providing therefor, in a comparable arm's-length transaction with
a Person that is not such a holder or an Affiliate.

         (b)      The limitation of paragraph (a) of this Section 6.7 does not

                                 ARTICLE VIII

                           THE ADMINISTRATIVE AGENT

         SECTION 8.1.     Appointment. Each Bank hereby irrevocably designates
and appoints JPMCB, as the Administrative Agent of such Bank under this
Agreement, and each such Bank hereby irrevocably authorizes JPMCB, as the
Administrative Agent for such Bank, to take such action on its behalf under the
provisions of this Agreement and to exercise such powers and perform such duties
as are expressly delegated to the Administrative Agent by the terms of this
Agreement, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or otherwise exist against the
Administrative Agent.

         SECTION 8.2.     Delegation of Duties. The Administrative Agent may
execute any of its duties under this Agreement by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties.

         SECTION 8.3.     Exculpatory Provisions. Neither the Administrative
Agent nor any of its officers, directors, employees, agents, attorneys-in-fact
or affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by it or any such Person under or in connection with this Agreement
(except for its or such Person's own gross negligence or willful misconduct), or
(b) responsible in any manner to any of the Banks for any recitals, statements,
representations or warranties made by the Borrower or any officer thereof
contained in this Agreement or in any certificate, report, statement or other
document referred to or provided for in, or received by the Administrative Agent
under or in connection with, this Agreement or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any Notes or for any failure of the Borrower to perform its obligations
hereunder or thereunder.  Except in respect of Section 3.1 or except as
otherwise expressly stated herein, the Administrative Agent shall not be under
any obligation to any Bank to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement, or to inspect the properties, books or records of the Borrower.

         SECTION 8.4.     Reliance by the Administrative Agent. The
Administrative Agent shall be entitled to rely, and shall be fully protected in
relying, upon any agreement (including this Agreement), note (including any
Note), writing, resolution, notice, consent, certificate, affidavit, letter,
cablegram, telegram or teletype message, statement, order or other document or
facsimile transmission or telephone conversation reasonably believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including counsel to
the Borrower), independent

                                      -53-

<PAGE>

accountants and other experts selected by the Administrative Agent. The
Administrative Agent may deem and treat the payee of any Note as the owner
thereof for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Administrative Agent. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement unless it shall first receive such advice or
concurrence of the Majority Banks as it deems appropriate or it shall first be
indemnified to its satisfaction by the Banks against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action. The Administrative Agent shall in all cases be fully protected
in acting, or in refraining from acting, under this Agreement and the Notes in
accordance with a request of the Majority Banks, and such request and any action
taken or failure to act pursuant thereto shall be binding upon all the Banks and
all future holders of the Notes.

         SECTION 8.5.     Notice of Default. The Administrative Agent shall not
be deemed to have knowledge or notice of the occurrence of any Default or Event
of Default hereunder unless the Administrative Agent has received notice from a
Bank or the Borrower referring to this Agreement, describing such Default or
Event of Default. In the event that the Administrative Agent receives such a
notice, the Administrative Agent shall give prompt notice thereof to the Banks.
The Administrative Agent shall take such action with respect to such Default or
Event of Default as shall be directed by the Majority Banks; provided that,
unless and until the Administrative Agent shall have received such directions,
the Administrative Agent may (but shall not be obligated to) take such action,
in accordance with the terms hereof, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable in the
best interests of the Banks.

         SECTION 8.6.     Non-Reliance on the Administrative Agent and Other
Banks. Each Bank expressly acknowledges that neither the Administrative Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates has made any representations or warranties to it and that no act by
the Administrative Agent hereinafter taken, including any review of the affairs
of the Borrower, shall be deemed to constitute any representation or warranty by
the Administrative Agent to any Bank. Each Bank represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative
Agent or any other Bank, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, financial and other condition and
creditworthiness of the Borrower and made its own decision to make its loans
hereunder and enter into this Agreement. Each Bank also represents that it will,
independently and without reliance upon the Administrative Agent or any other
Bank, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit analysis, appraisals and decisions
in taking or not taking action under this Agreement, and to make such
investigations as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Borrower. Except for notices, reports and other documents expressly required to
be furnished by the Borrower to the Administrative Agent hereunder, the
Administrative Agent shall not have any duty or responsibility to provide any
Bank with any information concerning the business, operations, property,
financial and other condition or creditworthiness of the Borrower which may come
into the possession of the Administrative Agent or any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates.

         SECTION 8.7.      Indemnification. The Banks agree to indemnify the
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to their respective Commitment Percentages in effect on the
date on which indemnification is sought under this Section 8.7 (or, if
indemnification is sought after the date upon which all of the Commitments shall
have terminated and the Obligations shall have been paid in full, ratably in
accordance with their respective Commitment Percentages immediately prior to
such termination), from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind whatsoever which may at any time (including at any
time following the payment of the Obligations or the Maturity Date) be imposed
on, incurred by or asserted against the Administrative Agent in any way relating
to or arising out of this Agreement, or any documents contemplated by or
referred to herein or the transactions contemplated hereby or any action taken
or omitted by the Administrative Agent under or in connection with any of the
foregoing; provided, however, that such indemnity shall not, as to the
Administrative Agent, be available to the extent that such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements are determined by a court of competent jurisdiction by
final and non-appealable judgment to have resulted from the Administrative
Agent's gross negligence or willful misconduct. The Agreements in this Section
8.7 shall survive the payment of the Obligations and the Maturity Date.

         SECTION 8.8.      The Administrative Agent in Its Individual Capacity.
JPMCB and its Affiliates may make loans to, accept deposits from and generally
engage in any kind of business with the Borrower as though JPMCB were not the
Administrative Agent hereunder.  With respect to Term Loans made by it and any
Note issued to it, JPMCB shall have the same rights and powers under this
Agreement as any Bank and may exercise the same as though it were not the
Administrative Agent, and the terms "Bank" and "Banks" shall include JPMCB and
such Affiliates in their individual capacities.

         SECTION 8.9.      Successor Administrative Agent. The Administrative
Agent may be removed at any time upon the written request of all of the Banks
(not including the Administrative Agent or its Affiliates) and the written
consent of the Borrower, such consent not to be unreasonably withheld, delivered
to the Administrative Agent and the Borrower. The Administrative Agent may
resign as Administrative Agent upon 10 days' notice to the Banks and the
Borrower. If the Administrative Agent shall resign or be removed as
Administrative Agent under this Agreement, then the Majority Banks shall appoint
from among the Banks a successor agent for the Banks which successor agent shall
be subject to approval by the Borrower, whereupon such successor agent shall
succeed to the rights, powers and duties of the Administrative Agent, and the
term "Administrative Agent" shall mean such successor agent effective upon its
appointment, and the former Administrative Agent's rights, powers and duties as
Administrative Agent shall be terminated, without any other or further act or
deed on the part of such former Administrative Agent or any of the parties to
this Agreement or any holders of the Notes. After any retiring Administrative
Agent's resignation or removal hereunder as Administrative Agent, the provisions
of this Article VIII shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under this
Agreement. In the event the Administrative Agent resigns or is removed pursuant
to this Section 8.9, all fees paid to the resigning Administrative Agent but not
yet accrued shall be transferred to the successor Administrative Agent.

                      THE JOINT LEAD ARRANGERS, ARRANGERS,
                               DOCUMENTATION AGENT

         SECTION 9.1.     The Joint Lead Arrangers, etc. The Borrower hereby
confirms the appointment of and designates J.P. Morgan Securities Inc. and
Salomon Smith Barney Inc., as Joint Lead Arrangers, Bank of America, N.A.,
Comerica Bank and Landesbank Schleswig- Holstein Girozentrale, Kiel and Standard
Chartered Bank, as Arrangers (the Joint Lead Arrangers and the Arrangers for
purposes of this Article XII, individually, an "Arranger" and collectively, the
"Arrangers") and Standard Chartered Bank, as Documentation Agent (the
Documentation Agent for purposes of this Article IX, the "Agent") under this
Agreement. The Arrangers and the Agent assume no responsibility or obligation
hereunder for servicing, enforcement or collection of the Obligations, or any
duties as agent for the Banks. The title "Joint Lead Arranger", "Arranger" or
"Documentation Agent" implies no fiduciary responsibility on the part of such
Arranger or Agent to the Banks or any other party to this Agreement and the use
of such title does not impose on any Arranger or Agent any duties or obligations
under this Agreement except as may be expressly set forth herein.

         SECTION 9.2.     Exculpatory Provisions. No Arranger or Agent nor any
of its respective officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by them under or in connection with this Agreement (except for its or for
such Person's own gross negligence or willful misconduct), or (b) responsible in
any manner to any of the Banks for any recitals, statements, representations or
warranties made by the Borrower or any officer thereof contained in this
Agreement or in any certificate, report, statement or other document referred to
or provided for in, or received by any Arranger or Agent under or in connection
with, this Agreement or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any Note or for any failure
of the Borrower to perform its obligations hereunder or thereunder. Except as
otherwise expressly stated herein, no Arranger or Agent shall be under any
obligation to any Bank to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement, or to inspect the properties, books or records of the Borrower.

         SECTION 9.3.     Arrangers and Agent. Bank of America, N.A., Comerica
Bank, Landesbank Schleswig-Holstein Girozentrale, Kiel and Standard Chartered
Bank and their respective affiliates may make loans to, accept deposits from and
generally engage in any kind of business with the Borrower as though Bank of
America, N.A., Comerica Bank, Landesbank Schleswig-Holstein Girozentrale, Kiel
and Standard Chartered Bank. were not an Arranger or Agent hereunder.

         SECTION 9.4.     Non-Reliance on the Arrangers, Agent and Other Banks.
Each Bank expressly acknowledges that no Arranger or Agent nor any of its
respective officers, directors, employees, agents, attorneys-in-fact or
affiliates has made any representations or warranties to it and that no act by
any Arranger or Agent hereinafter taken, including any review of the affairs of
the Borrower, shall be deemed to constitute any representation or warranty by
such Arranger or Agent to any Bank. Each Bank represents to the Arrangers and
the Agent that

                                      -56-

<PAGE>

it has, independently and without reliance upon any Arranger or Agent or any
other Bank, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Borrower and made its own decision to make its loans hereunder and enter into
this Agreement. Each Bank also represents that it will, independently and
without reliance upon any Arranger or Agent or any other Bank, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and decisions in taking or not taking
action under this Agreement, and to make such investigations as it deems
necessary to inform itself as to the business, operations, property, financial
and other condition and creditworthiness of the Borrower. No Arranger or Agent
shall have any duty or responsibility to provide any Bank with any information
concerning the business, operations, property, financial and other condition or
creditworthiness of the Borrower which may come into the possession of such
Arranger or Agent or any of its respective officers, directors, employees,
agents, attorneys-in-fact or affiliates.

Agent, the Joint Lead Arrangers and the Arrangers harmless from liability for
the payment of all of their out-of-pocket costs and expenses reasonably incurred
by any of them and arising in connection with any Default or Event of Default or
the enforcement of, or the amendment, modification, waiver and/or preservation
of any rights under, this Agreement, the Notes or otherwise in connection

disbursements of counsel of each Bank, the Administrative Agent, the Joint Lead
Arrangers and the Arrangers, and all stamp taxes (including interest and
penalties, if any), recording taxes and fees and filing taxes and fees which may
be payable in respect thereof.

         SECTION 10.4.    Amendments and Waivers. No waiver, amendment,
supplement or modification hereto shall be effective unless in writing and

Notes or any Default or Event of Default and its consequences; provided,
however, no such waiver and no such amendment, supplement or modification shall:

         (a)      (i)      extend the maturity of any of the Obligations, extend
the time of payment of interest thereon, or extend the Maturity Date;

                  (ii)     reduce the principal amount of the Obligations,
         reduce the rate of interest thereon, or reduce the amount or change the
         method of calculation of any Fees;

                  (iii)    amend, modify or waive any provision of this
         Section 10.4;

         Any such waiver and any such amendment, supplement or modification
shall apply equally to each of the Banks and shall be binding upon the Borrower,
the Banks, the Administrative Agent, the Joint Lead Arrangers, the Arrangers,
the Documentation Agent and all future holders of the Notes. In the case of any
waiver, the Borrower, the Banks, the Joint Lead Arrangers, the Arrangers, the
Documentation Agent and the Administrative Agent shall be restored to their
former positions and rights hereunder and under the outstanding Notes, and any
Default or Event of Default waived shall be deemed to be cured and not

the foregoing Persons (each such Person being called an "Indemnitee") from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever, including, without limitation, all reasonable fees, documented as to
the scope of services provided, and disbursements of counsel (including the
allocated cost of internal counsel) which may at any time (including at any time
following the payment of the Obligations or the Maturity Date) be imposed on or
incurred by any such Indemnitee in connection with the investigation of,
preparation for, participation in or outcome of any pending or threatened claim
or cause of action relating to or arising out of this Agreement or any documents
contemplated by or referred to herein or the transactions contemplated hereby or
thereby or any action taken or omitted by such Indemnitee under or in connection
with any of the foregoing and which would not have been incurred by or asserted
or awarded against such indemnified party but for such Indemnitee being involved
with the Agreement or any documents contemplated by or referred to herein or the
transactions contemplated hereby or any action taken or omitted by such
Indemnitee in connection with any of the foregoing; provided, however, that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements are determined by a court of competent
jurisdiction by final and non-appealable judgment to have resulted from the
gross negligence or willful misconduct of such Indemnitee.

         (b)     This Section 10.6 shall survive the termination of this
Agreement and the payment of the Obligations.

         SECTION 10.7.     Notices.

given or made when received by the party to whom such communication was sent.

         (b)     Notices and other communications to the Banks hereunder may be
delivered or furnished by electronic communications pursuant to procedures
approved by the Administrative Agent; provided that the foregoing shall not
apply to notices pursuant to Article II unless otherwise agreed by the
Administrative Agent and the applicable Bank. The Administrative Agent or the

communications to it hereunder by electronic communications pursuant to
procedures approved by it; provided that approval of such procedures may be
limited to particular notices or communications.

         SECTION 10.9.    Survival of Agreements and Representations. All
covenants, agreements, representations and warranties made herein, in the Notes,
or in any certificate delivered pursuant hereto or thereto shall survive the
execution and delivery hereof and the Term Loans made hereunder.

         SECTION 10.10.   Benefit of Agreement; Assignment. This Agreement
shall be binding upon the Borrower, its successors and assigns, and shall inure
to the benefit of the Joint Lead Arrangers, the Arrangers, the Documentation
Agent, the Administrative Agent and the Banks and their respective successors
and assigns except that (a) the Borrower may not transfer or assign any or all
of its rights or obligations hereunder except with the unanimous consent of all
the Banks; (b) an assignment by a Bank of its Commitment, its Note and its Term
Loans can only be made to a bank or financial institution organized and licensed
under the laws of Mexico or a financial institution registered with the
Hacienda; and (c) no Bank may assign its Commitment, its Note and the Term Loans
made by such Bank and no Bank may make or cause to be made its Term Loans
hereunder through any other Person, except pursuant to an instrument of
assignment in substantially the form of Exhibit C (an "Assignment and
Acceptance") and with the consent of the Administrative Agent and the Borrower
(which consent (x) in each case shall not be unreasonably withheld, (y) in the
case of the Borrower, shall not be required in the case of an assignment to a
Person party to this Agreement or a branch, agency or Subsidiary thereof (a
"Bank Affiliate") or after the occurrence and during the continuance of an Event
of Default and (z) in the case of the Administrative Agent shall not be required
in the case of an assignment to a Bank Affiliate); provided, however, that (i)
the Borrower shall not be required to pay any further amounts pursuant to
Sections 2.11, 2.13 and 2.14 than would have been required to be paid but for
the transfer of such Bank's interest to a Bank Affiliate or the making of Term
Loans through another office or Subsidiary of such Bank, except as provided in
Section 2.13, (ii) any such assignment shall be in a minimum amount of
US$1,000,000 and (iii) the Assignee shall pay a fee of US$3,500 to the
Administrative Agent prior to the consummation of such assignment (other than an
assignment to a Bank Affiliate). Nothing herein shall prohibit any Bank from
pledging or assigning any Note to any Federal Reserve Bank in accordance with
applicable law and without compliance with the foregoing provisions of this
Section 10.10; provided, however, that such pledge or assignment shall not
release such Bank from its obligations hereunder.

         SECTION 10.11.   Participation. Notwithstanding the provisions of
Section 10.10, each Bank shall have the right from time to time to create and
sell one or more participations in its rights under this Agreement, its Note and
the Term Loans made by it to a bank or financial institution organized and
licensed under the laws of Mexico or a financial institution registered with the
Hacienda. Each Bank agrees to notify the Borrower as promptly as practicable of
the consummation of the sale of a participation in its rights under this
Agreement, its Note and the Term Loans made by it. No agreement or other
arrangement governing any such creation and sale (a "Participation Agreement")
shall confer upon the purchaser of such interest

                                      -62-

<PAGE>

(a "Participant") any right to contact, negotiate with or seek information from
the Borrower under this Agreement or such Bank's Note or to enforce this
Agreement or such Bank's Note against the Borrower directly, except as provided
below. Any Participation Agreement shall (a) prohibit the assignment or sale by
the Participant of any subparticipation interest and (b) permit the Bank to
consent to waivers, amendments, modifications or supplements of this Agreement
without the consent of the Participant, except in the case of waivers,
amendments or modifications extending the maturity of any Term Loan or Note in
respect of which such Participation was granted, or reducing the rate or
extending the time for payment of any installment of interest thereon or
reducing the principal thereof, or reducing the amount or basis of calculation
of any Fees to accrue in respect thereof. Notwithstanding the foregoing, any
Participant shall be entitled to the benefits of Sections 2.11, 2.13 and 2.14
pursuant to its Participation Agreement as if such Participant were a Bank named
herein, provided, however, that the Borrower shall not be required to pay any
further amounts pursuant to such Sections than would have been required to be
paid but for the sale to such Participant of such Participant's participation
interest.

         SECTION 10.12.   Right of Set-off. Upon the occurrence and during the
continuance of any Event of Default, the Administrative Agent and the Banks are
hereby authorized at any time and from time to time, without notice to the
Borrower (any such notice being expressly waived by the Borrower) and 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, in any currency) at
any time held and other indebtedness at any time owing by the Administrative
Agent or the Banks to or for the credit or the account of the Borrower against
any and all of the obligations of the Borrower now or hereafter existing under
this Agreement or the Notes, irrespective of whether or not the Administrative
Agent or the Banks shall have made any demand hereunder and although such
obligations may be unmatured. Each of the Banks and the Administrative Agent
agrees promptly to notify the Borrower no later than five Business Days after
any such setoff and application; provided, however, that the failure to give
such notice shall not affect the validity of such setoff and application.

         SECTION 10.13.   SUBMISSION TO JURISDICTION; VENUE; SERVICE; WAIVER OF
JURY TRIAL. EACH OF THE PARTIES HERETO (AND ITS SUCCESSORS AND ASSIGNS) (i)
AGREE THAT ANY CLAIM, SUIT, ACTION OR PROCEEDING BROUGHT BY ANY PARTY OR
SUCCESSOR THERETO ARISING OUT OF THIS AGREEMENT OR ANY NOTE SHALL BE SUBJECT TO
THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK OR THE UNITED STATES
DISTRICT COURT IN EACH CASE LOCATED IN THE BOROUGH OF MANHATTAN IN NEW YORK
CITY, TO THE JURISDICTION OF ANY COMPETENT COURT IN THE PLACE OF ITS CORPORATE
DOMICILE AND TO APPELLATE COURTS THEREFROM AND EACH OF THE PARTIES HEREBY
EXPRESSLY AND IRREVOCABLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO SUCH
JURISDICTION FOR SUCH PURPOSE AND (ii) TO THE FULLEST EXTENT PERMITTED BY LAW,
(A) IRREVOCABLY WAIVES ANY OBJECTION IT MAY HAVE AT ANY TIME TO THE LAYING OF
VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR ANY OTHER PRINCIPAL DOCUMENT BROUGHT IN ANY SUCH COURT, (B)
IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH SUIT, ACTION OR

                                      -63-

<PAGE>

PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM;
AND (C) IRREVOCABLY WAIVES THE RIGHT TO OBJECT, WITH RESPECT TO SUCH CLAIM,
SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT, THAT SUCH COURT DOES NOT
HAVE JURISDICTION OVER IT. EACH OF THE PARTIES HERETO HEREBY EXPRESSLY AND
IRREVOCABLY WAIVES ALL RIGHTS OF JURISDICTION IN ANY SUCH ACTION OR PROCEEDING,
WHICH IT MAY NOW OR HEREAFTER BE AFFORDED BY LAW, IN ANY OTHER FORUM. EACH OF
THE PARTIES HERETO FURTHER AGREES THAT A FINAL JUDGMENT IN ANY SUCH SUIT, ACTION
OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY
SUIT ON THE JUDGMENT OR IN ANY MANNER PROVIDED BY LAW. TO THE FULLEST EXTENT
PERMITTED BY LAW, EACH OF THE PARTIES HERETO (AND THEIR RESPECTIVE SUCCESSORS
AND ASSIGNS) WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING
ARISING OUT OF OR RELATING TO ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS
AGREEMENT. FOR THE PURPOSE OF PROCEEDINGS IN THE COURTS OF THE STATE OF NEW YORK
AND THE UNITED STATES COURTS FOR THE SOUTHERN DISTRICT OF NEW YORK, IN EACH CASE
SITTING IN THE BOROUGH OF MANHATTAN, THE BORROWER HEREBY IRREVOCABLY DESIGNATES
AS OF THE EFFECTIVE DATE CT CORPORATION SYSTEM WITH OFFICES CURRENTLY LOCATED AT
111 EIGHTH AVENUE, NEW YORK, NEW YORK 10011 AS ITS AGENT FOR SERVICE OF PROCESS.
IN THE EVENT THAT SUCH AGENT OR ANY SUCCESSOR SHALL CEASE TO BE LOCATED IN THE
BOROUGH OF MANHATTAN, THE BORROWER SHALL PROMPTLY AND IRREVOCABLY BEFORE THE
RELOCATION OF SUCH AGENT FOR SERVICE OF PROCESS, IF PRACTICABLE, OR PROMPTLY
THEREAFTER DESIGNATE A SUCCESSOR AGENT, WHICH SUCCESSOR AGENT SHALL BE LOCATED
IN THE BOROUGH OF MANHATTAN, AND NOTIFY THE ADMINISTRATIVE AGENT THEREOF, TO
ACCEPT ON ITS BEHALF SERVICE OF ANY AND ALL PROCESS OR OTHER DOCUMENTS WHICH MAY
BE SERVED IN ANY ACTION OR PROCEEDING IN ANY OF SUCH COURTS AND FURTHER AGREES
THAT SERVICE UPON SUCH AGENT SHALL CONSTITUTE VALID AND EFFECTIVE SERVICE UPON
THE BORROWER AND THAT FAILURE OF ANY SUCH AGENT TO GIVE ANY NOTICE OF SUCH
SERVICE TO THE BORROWER SHALL NOT AFFECT THE VALIDITY OF SUCH SERVICE OR ANY
JUDGMENT RENDERED IN ANY ACTION OR PROCEEDING BASED THEREON. EXCEPTING THE
BORROWER, EACH OF THE PARTIES HERETO AGREES THAT SERVICE OF ANY AND ALL SUCH
PROCESS OR OTHER DOCUMENTS ON SUCH PERSON MAY ALSO BE EFFECTED BY REGISTERED
MAIL TO ITS ADDRESS AS SET FORTH IN SECTION 10.7 OR SCHEDULE 1.1(b). WITH
RESPECT TO THE BORROWER, SERVICE, OF ANY AND ALL SUCH PROCESS OR OTHER DOCUMENTS
TO CT CORPORATION OR SUCH OTHER AGENT FOR SERVICE OF PROCESS DESIGNATED BY THE
BORROWER IN ACCORDANCE WITH THIS AGREEMENT, SERVICE OF PROCESS SHALL CONSTITUTE
VALID AND EFFECTIVE SERVICE ONLY IF MADE IN PERSON.

         SECTION 10.14.    Judgment Currency. All payments made under this
Agreement and the Notes shall be made in New York, New York to such account as
may be directed by the payee from time to time in United States Dollars, and, if
for any reason any payment made hereunder is made in a currency (the "Other
Currency") other than United States Dollars, then to the extent that the payment
actually received by the Banks, the Joint Lead Arrangers, the Arrangers, the
Documentation Agent or the Administrative Agent, when converted into United
States Dollars at the Rate of Exchange (as defined below) on the date of payment
(or, if conversion on such date is not practicable, as soon thereafter as it is
practicable for the Banks, the Joint Lead Arrangers, the Arrangers, the
Documentation Agent or the Administrative Agent to purchase United States
Dollars) falls short of the amount due under the terms of this Agreement or any
Note, the Borrower, shall, as a separate and independent obligation of the
Borrower, indemnify the Banks, the Joint Lead Arrangers, the Arrangers, the
Documentation Agent and the Administrative Agent and hold the Banks, the Joint
Lead Arrangers, the Arrangers, the Documentation Agent and the Administrative
Agent harmless against the amount of such shortfall. As used in this Section
10.14, the term "Rate of Exchange" means the rate at which the Banks, the Joint
Lead Arrangers, the Arrangers, the Documentation Agent or the Administrative
Agent are able on the relevant date to purchase United States Dollars with the
Other Currency and shall include any premiums and costs of exchange payable in
connection with the purchase of or conversion into, United States Dollars.

         SECTION 10.15.    Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by the different parties hereto in
separate counterparts, each of which when so executed and delivered shall be
deemed to be an original and all of which taken together shall constitute one
and the same instrument.

         SECTION 10.16.    Waiver of Immunities. To the extent that the Borrower
has or hereafter may acquire any immunity from jurisdiction of any court or from
any legal process (whether through service or notice, attachment prior to
judgment, attachment in aid of execution, execution or otherwise) with respect
to itself or its property, the Borrower hereby irrevocably waives such immunity
in respect of its obligations under this Agreement and the Notes. The foregoing
waiver is intended to be effective to the fullest extent now or hereafter
permitted by applicable law.

          SECTION 10.17.   Severability. To the fullest extent permitted by law,
any provision of this Agreement which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof or affecting the validity or enforceability of such provision
in any other jurisdiction, and the remaining portion of such provision and all
other remaining provisions hereof will be construed to render them enforceable.

          SECTION 10.18.   Confidentiality. Each of the Joint Lead Arrangers,
the Arrangers, the Documentation Agent, the Administrative Agent and each of the
Banks agrees that it will not disclose without the prior consent of the Borrower
(other than to its affiliates, employees, auditors or counsel or to another
Bank) any information with respect to the Borrower which is furnished pursuant
to this Agreement or any Note except that any such Person may disclose any such
information (a) as has become generally available to the public other than by a
breach by such Person of this Section 10.18, (b) as may be requested or required
by any

                                      -65-

Governmental Authority having or claiming to have jurisdiction over such Person
(provided that such Person does not object to such body's claim of jurisdiction
over it) or to the Federal Reserve Board or the Federal Deposit Insurance
Corporation or similar organizations (whether in the United States or elsewhere)
or their successors, (c) as may be required in response to any summons or
subpoena or any law, order, governmental direction, regulation or ruling
applicable to such Person, or (d) to any prospective participant or assignee in
connection with any contemplated transfer pursuant to Section 10.10 or Section
10.11, provided that such prospective transferee shall have been made aware of
this Section 10.18 and shall have agreed to be bound by its provisions as if it
were a party to this Agreement.

          SECTION 10.19.   No Waiver; Remedies. No failure on the part of the
Administrative Agent, the Joint Lead Arrangers, any Arranger, the Documentation
Agent or any of the Banks to exercise, and no delay in exercising, any right
hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise of any right hereunder preclude any other or further exercise thereof
or the exercise of any other right. The remedies herein provided are cumulative
and not exclusive of any remedies provided by law.

          SECTION 10.20.   Prior Agreements Superseded. As of the Effective
Date, this Agreement shall completely and fully supersede all prior undertakings
or agreements, both written and oral, between or among the Borrower, the Joint
Lead Arrangers, the Arrangers, the Documentation Agent, the Administrative Agent
and/or the Banks, relating to the acquisition by the Banks of their Commitments,
including, but not limited to, those contained in any mandate letter between the
Borrower and the Joint Lead Arrangers executed in anticipation of the
acquisition by the Banks of their Commitments but excluding the Fee Letters
referred to herein.
