key measures of the Company’s success and to reward these employees for achieving the key
measures of the Company’s success. This Plan is not intended to be a performance-based plan

(j) “Maximum Award” shall mean an Award level that may be paid if the maximum level

of the Performance Goal(s) is achieved in the Performance Year.

(r) “Threshold Award” shall mean an Award level that may be paid if the threshold

	3.	 	ELIGIBILITY and PARTICIPATION.

(a) In General. An Eligible Employee of an Employer will become a Participant for
a Performance Year if he or she is selected by the Company, subject to the approval of the
Committee, as eligible to participate in the Plan. Participants will be determined at the
beginning of each Performance Year, and participation in the Plan during one Performance
Year does not guarantee continued participation in future Performance Years. The Company,
subject to the approval of the Committee, may add Participants during the course of a
Performance Year as it deems appropriate in its sole discretion. A Participant must be

2

 

employed by an Employer on the last business day of a Performance Year in order to be
eligible to receive an Award, except as provided in Section 3(b) below.

(b) Prorations for Partial Year. A Participant who is not an Eligible Employee for
an entire Performance Year may receive an Award for any portion of the Performance Year
that he or she is an Eligible Employee, subject to Section 5 of the Plan and the following:

	 	1)	 	New Hires, Transfers. A Participant who becomes an
Eligible Employee on account of being hired or transferred during a
Performance Year will be eligible for a prorated Award for such Performance
Year. The amount of the prorated Award shall be equal to the full amount of
the Award otherwise determined under Section 4 of the Plan, multiplied by the
Proration Fraction.
	 
	 	2)	 	Death or Disability. A Participant who has a
termination of employment during a Performance Year on account of death or
Disability will be eligible for a prorated Award for such Performance Year.
The amount of the prorated Award shall be equal to the full amount of the
Award for such individual for the Performance Year in which the death or
Disability occurs, multiplied by the Proration Fraction. With respect to the
calculation of an Award for purposes of this provision, the Participant’s rate
of base salary in effect for the last full payroll period of his or her
employment shall be used.

Notwithstanding the foregoing, the Committee may, in its discretion, based upon the
recommendation of the Company, determine that a Participant who is added during the course
of a Performance Year will be eligible for an Award for the Performance Year that is not a
prorated Award and that therefore is not multiplied by the Proration Fraction.

(c) Leaves. A Participant who is on Leave for an aggregate of more than three (3)
months during a Performance Year will not be eligible for an Award for such Performance
Year.

	4.	 	DETERMINATION OF AWARDS.

(a) Establishment of Performance Goal. The Company shall establish objective
Performance Goals for each Award after the beginning of each Performance Year subject to
the approval of the Committee. The Performance Goals may be based upon the performance of
the Company, the Employer, or any operating unit level, division or function thereof, and
may be applied either alone or relative to the performance of other businesses or
individuals (including industry or general market indices),

3

 

based on one or more of the Performance Measures. Performance Goals may be expressed as
whole dollar amounts, percentages or growth rates. Performance Goals will be determined
each year by the senior management of the Company, with consultation from other third party
sources, and are subject to the approval of the Committee. Performance Goals will be set
for each Performance Measure as follows: threshold, target and maximum. No Award will be
made under a Performance Measure if results are below the threshold level.

(b) Establishment of Awards. The Company shall also establish, subject to the
approval of the Committee, the Threshold Award, the Target Award and the Maximum Award
payable to a Participant if the Performance Goal(s) is achieved. The payment of any Award
shall be subject to achievement of the applicable Performance Goals and certification by
the President of the Company to the degree to which each of the Performance Goals have been
attained. The Committee will consider such certification in its determination hereunder of
whether an Award shall be paid. Threshold Awards, Target Awards and Maximum Awards will be
expressed as a percentage of a participant’s base salary and correspond to salary grades.
Target Award percentages will be determined each year by the senior management of the
Company, with consultation from other third party sources, and are subject to the approval
of the Committee. For purposes of determining the amount of an Award, the Participant’s
rate of base salary in effect for the last full payroll period of the Performance Year to
which the Award pertains shall be used.

(c) Maximum Individual Award. The maximum amount of any Maximum Award to a
Participant for any Performance Year shall be the lesser of $2,000,000 or 200 percent of a
Participant’s Target Award for a Performance Year. Threshold Award amounts will be 50% of
the potential Target Award amount (multiplied by the Performance Measure weighting).

(d) Adjustments to Awards. The Committee may, in its discretion, modify the amount
of any Award based on such criteria as it shall determine, including, but not limited to,
financial results, individual performance, safety performance, business unit and site
accomplishments, and other factors tied to the success of the Company or any of its
business units. The Committee shall retain the discretion to adjust any Award downward.
There is no obligation of uniformity of treatment of Participants under the Plan.

(e) Determination of Attainment of Performance Goals. The Committee may determine
in its sole discretion how results will be calculated related to the Performance Measures
selected for a particular Performance Year. In determining results for a Performance Year,
the Committee may approve adjustments in the calculations to reflect extraordinary, unusual
or non-recurring items.

4

 

	5.	 	PAYMENT OF AWARDS.

(a) Time of Payment. An Award shall be paid to a Participant in cash as soon as
practicable after the Committee has certified in writing that the Performance Goal(s) for
the Performance Year have been achieved; provided, however, in no event will the Award with
respect to a Performance Year be paid to a Participant later than the 15th day
of the third month following the end of such Performance Year. No absolute right to any
Award shall be considered as having accrued to any Participant prior to the payment of the
Award. Awards payable to other Participants who have had a termination of employment on
account of death or Disability during the Performance Year shall be payable in accordance
with Section 3(b) of the Plan and at the same time other Participants receive Awards under
the Plan.

(b) Termination of Employment Other Than on Account of Death or Disability. A
Participant who has a termination of employment other than on account of death or
Disability prior to the last day of a Performance Year shall not be paid any Award for such
Performance Year.

(c) Termination of Employment on Account of Death or Disability. A Participant who
has a termination of employment on account of death or Disability after the end of the
Performance Year but prior to the payment date for Awards for such Performance Year shall
be paid the full amount of any Award for such Performance Year, determined under Section 4
of the Plan (in addition to any amount determined under Section 3(b) for the Performance
Year in which the termination of employment on account of death or Disability occurs). If
the Participant dies prior to receiving payment of an Award, any Award payable under the
Plan to such Participant shall be paid to the Participant’s estate.

(d) Withholding. Awards are subject to withholding for applicable federal, state
and local taxes.

	6.	 	PLAN ADMINISTRATION.

(a) Administration. The Plan shall be administered by the Committee. The
Committee shall have full discretionary authority to establish the rules and regulations
relating to the Plan, to interpret the Plan and those rules and regulations, to determine
the Awards and the Performance Measures applicable to each Award, to approve all Awards, to
decide the facts in any case arising under the Plan, and to make all other determinations
and to take all other actions necessary or appropriate for the proper administration of the
Plan. In making any determinations under or referred to in the Plan, the Committee shall
be entitled to rely on opinions, reports or statements of employees of the Company and of
counsel, public accountants, and other professional or expert persons. The Committee’s

5

 

administration of the Plan, including all such rules and regulations, interpretations,
selections, determinations, approvals, decisions, delegations, amendments, terminations and
other actions, shall be final and binding on the Company and its stockholders and all
employees, including Participants and their beneficiaries. No member of the Committee
shall be liable for any action taken or determination made in good faith with respect to
the Plan or any Award.

(b) Delegation. Except to the extent prohibited by applicable law or the
applicable rules of a stock exchange, the Committee may allocate all or any portion of its
responsibilities and powers to any one or more of its members, and may delegate all or any
part of its responsibilities and powers for administering the Plan to one or more persons
as the Committee deems appropriate, and at any time may revoke any such allocation or
delegation.

	7.	 	AMENDMENT OR TERMINATION OF PLAN. The Committee may amend (in whole or in part) or terminate
the Plan at any time, effective at such date as the Committee may determine. The Company also
may amend (in whole or in part) or terminate the Plan at any time effective as of such date as
the Company may determine, provided, however, any such amendment of the Plan by the Company is
subject to the approval of the Committee.
	 
	8.	 	MISCELLANEOUS PROVISIONS.

(a) Awards Not Transferable. A Participant’s right and interest under the Plan may
not be assigned or transferred. Any attempted assignment or transfer shall be null and
void and shall extinguish, in the Committee’s sole discretion, the Company’s obligation
under the Plan to pay Awards with respect to the Participant.

(b) Effect of Awards on Other Compensation.

	 	1)	 	Awards shall not be considered eligible pay under other
plans, benefit arrangements or fringe benefit arrangements of the Company,
unless otherwise provided under the terms of other plans.
	 
	 	2)	 	To the extent provided in the applicable benefit plan or
benefit arrangement of an Employer, amounts payable as Awards will be reduced
in accordance with the Participant’s compensation reduction election, if any,
in effect under other plans at the time the Award is paid.

(c) No Employment Rights. This Plan is not a contract between the Employer and any
employee or Participant. Neither the Plan, nor any action taken hereunder, shall be
construed as giving to any Participant the right to be retained in the employ of the
Employer. Nothing in the Plan

6

 

shall limit or affect in any manner or degree the normal and usual powers of management,
exercised by the officers and the Board or any committee of the Board, to change the duties
or the character of employment of any employee or to remove an individual from the
employment of the Employer at any time, all of which rights and powers are expressly
reserved.

(d) Unfunded Plan. The Plan shall be unfunded. No Employer shall be required to
establish any special or separate fund, or to make any other segregation of assets, to
assure payment of Awards. Awards shall be paid solely from the general assets of the
Participant’s Employer, to the extent the payments are attributable to services for the
Employer. To the extent any person acquires a right to receive payments from an Employer
under the Plan, the right is no greater than the right of any other unsecured general
creditor.

(e) Applicable Law. The Plan shall be governed by the laws of the State of
Missouri and applicable federal law.

Exchange Rates shall become effective as of such Revaluation Date and shall be the Exchange Rates
employed in converting
any amounts between the applicable currencies until the next Revaluation Date to occur. Except
for purposes of financial statements delivered by Loan Parties hereunder or calculating financial
covenants hereunder or except as otherwise provided herein, the applicable amount of any currency
(other than Dollars) for

Credit Agreement  22

 

purposes of the Loan Documents shall be such Dollar Equivalent amount as
so determined by the Administrative Agent.

     (b) Wherever in this Agreement in connection with a Tranche A2 Commitment or prepayment of a
Tranche A2 Loan, an amount, such as a required minimum or multiple amount, is expressed in Dollars,
such amount shall be the Peso Equivalent of such Dollar amount (rounded to the nearest unit of
Pesos, with 0.5 of a unit being rounded upward), as determined by the Administrative Agent.

ARTICLE II.

LOANS, ETC.

     SECTION 2.1 The Loans. (a) The Tranche Al Loans. Subject to the terms and
conditions set forth herein, each Tranche Al Lender severally agrees to make revolving loans in
Dollars (collectively, the “Tranche A1 Loans”) to the Borrower from time to time during the Tranche
A Commitment Period in such Tranche A1 Lender’s Tranche A1 Revolving Percentage of such aggregate
amounts as the Borrower may from time to time request under the Tranche Al Loans; provided that (i)
the aggregate amount of Tranche A1 Loans requested by the Borrower to be made on a Borrowing Date
must be in a minimum of US$5,000,000 and integral multiples of US$1,000,000 in excess thereof and
(ii) no Tranche Al Lender shall be permitted or required to make any Tranche A1 Loan if after
giving effect to such Tranche A1 Loans: (A) the sum of (1) the principal amount under all Tranche
Al Loans outstanding and (2) the Dollar Equivalent of the principal amount under all Tranche A2
Loans outstanding would exceed an amount equal to (x) US$30,000,000 minus (y) the amount of all
reductions of Revolving Commitments made in accordance with Section 2.7; (B) the principal
amount under all Tranche Al Loans outstanding would exceed an amount equal to (x) US$19,521,000
minus (y) the amount of all reductions of Tranche Al Commitments made in accordance with
Section 2.7; (C) there would be more than six distinct Interest Periods applicable to
Revolving Loans; or (D) outstanding Tranche Al Loans of such Tranche Al Lender would exceed its
Tranche Al Commitment. Subject to the foregoing, Tranche A1 Loans may be repaid and reborrowed from
time to time.

     (b) The Tranche A2 Loans. Subject to the terms and conditions set forth herein, each
Tranche A2 Lender severally agrees to make revolving loans in Pesos (collectively, the “Tranche A2
Loans”) to the Borrower from time to time during the Tranche A Commitment Period in such Tranche A2
Lender’s Tranche A2 Revolving Percentage of the Peso Equivalent of such aggregate amounts as the
Borrower may from time to time request under the Tranche A2 Loans; provided that (i) the aggregate
amount of Tranche A2 Loans requested by the Borrower to be made on a Borrowing Date must be in a
minimum of the MXP$50,000,000 and integral multiples of MXP$10,000,000 in excess thereof and (ii)
no Tranche A2 Lender shall be permitted or required to make any Tranche A2 Loan if after giving
effect to such Tranche A2 Loans, (A) the sum of (1) the principal amount under all Tranche A1 Loans
outstanding and (2) the Dollar Equivalent of the principal amount under all Tranche A2 Loans
outstanding would
exceed an amount equal to (x) US$30,000,000 minus (y) the amount of all reductions of
Revolving Commitments made in accordance with Section 2.7; (B) the principal amount under
all Tranche A2 Loans outstanding would exceed an amount equal to (x) the Peso Equivalent of
US$10,479,000 minus (y) the amount of all reductions in Tranche A2 Commitments made in accordance
with Section 2.7; (C) there would be more than six distinct Interest Periods

Credit Agreement  23

 

applicable to
Revolving Loans; or (D) outstanding Tranche A2 Loans of such Tranche A2 Lender would exceed its
Tranche A2 Commitment. Subject to the foregoing, Tranche A2 Loans may be repaid and reborrowed from
time to time.

     (c) The Tranche B Loans. Subject to the terms and conditions set forth herein, each
Tranche B Lender severally agrees to make a term loan in Dollars (its “Tranche B Loan”) to the
Borrower on any one Business Day (the “Tranche B Borrowing Date”) during the Tranche B Commitment
Period in an aggregate principal amount outstanding not to exceed the Tranche B Commitment of such
Tranche B Lender and, as to all Tranche B Lenders, in an aggregate principal amount not to exceed
US$76,000,000. The Tranche B Loans may, at the Borrower’s election pursuant to the applicable
Notice of Borrowing/Continuation, have at any time up to three distinct Dollar Interest Periods,
each such Dollar Interest Period being applied to such portion of the Tranche B Loans as the
Borrower shall designate in its Notice of Borrowing/Continuation for the Tranche B Loans. Any
amounts not borrowed on the Tranche B Borrowing Date with respect to the Tranche B Loans may not be
borrowed thereafter and any available amounts not requested to be borrowed under the Tranche B
Loans prior to the termination of the Tranche B Commitment Period shall result in the pro rata
irrevocable termination of an equivalent amount of the Tranche B Commitments on the earlier of (i)
the date on which the Administrative Agent receives the Notice of Borrowing/Continuation with
respect to the Tranche B Loans or (ii) the termination of the Tranche B Commitment Period.

     SECTION 2.2 Notes. The Loans made by each Lender shall be evidenced by promissory
notes which qualify as pagarés under Mexican law, issued by the Borrower and guaranteed (por aval)
by the then existing Guarantors (subject to Section 6.13) substantially in the form of
Exhibit A (for Dollar Loans) and Exhibit B (for Tranche A2 Loans) (each a “Note”), delivered to the
Administrative Agent on behalf of each of the Lenders on or before the Initial Borrowing Date,
appropriately completed, representing the full amount of each such Lender’s Tranche A1 Commitment,
Tranche A2 Commitment or Tranche B Commitment, as the case may be; provided that in case of
conflict between the terms of this Agreement and any such Note, the terms of this Agreement shall
prevail and the Lenders shall not be entitled to claim amounts due under the Notes in excess of
amounts due under this Agreement.

     SECTION
2.3 Borrowings and Continuations. The Borrower shall give the Administrative
Agent irrevocable notice of a request for the borrowing of any Loans hereunder, or the continuation
of Dollar Loans hereunder, substantially in the form of Exhibit G (which notice must be received by
the Administrative Agent prior to 12:00 noon, New York City time, at least three Business Days
prior to the requested Borrowing Date for a Loan or, in the case of continuation of Dollar Loans,
at least three Business Days prior to the end of the then current Dollar Interest Period for such
Dollar Loans), specifying (a) the
Tranche under which the Loans are to be made or continued, (b) the aggregate amount of the
Loans to be borrowed or continued, (c) the requested Borrowing Date (or, as applicable, date of
continuation, which shall be the Dollar Interest Payment Date for such Dollar Loans) and (d) with
respect to Dollar Loans, the Dollar Interest Period applicable to each portion of such Dollar Loans
(the “Notice of Borrowing/Continuation”). Each borrowing or continuation of Dollar Loans shall be
in a principal amount of US$5,000,000 and integral multiples of US$1,000,000. Each borrowing of
Tranche A2 Loans shall be in a principal amount of MXP$50,000,000 and integral multiples of
MXP$10,000,000 in excess thereof. Upon receipt of a Notice of Borrowing/Continuation, the

Credit Agreement  24

 

Administrative Agent shall promptly notify each Lender that has a Commitment with respect to the
relevant Tranche of the amount of each Loan to be made or Dollar Loan to be continued by such
Lender and the other relevant terms thereof. Not later than 1:00 p.m., New York City time, on the
relevant Borrowing Date each such Lender shall make available to the Administrative Agent an amount
in immediately available funds in Dollars or Pesos, as applicable, equal to the Loan to be made by
such Lender, at the applicable Administrative Agent’s Office. Unless the Administrative Agent
determines that any applicable condition specified in Article IV has not been satisfied,
the Administrative Agent shall credit the amounts so received, in like funds, to the account of the
Borrower maintained with the Administrative Agent in New York City, in the case of Dollar Loans, or
in Mexico City, in the case of Tranche A2 Loans. In furtherance of the foregoing, the Borrower
hereby irrevocably authorizes the Administrative Agent to apply such amounts as the Borrower shall
direct in the Notice of Borrowing/Continuation.

     SECTION 2.4 Several Obligations; Remedies Independent. The obligations of the Lenders
hereunder to make Loans and to make payments pursuant to Section 11.2(c) are several and
not joint. The failure of any Lender to make any Loan or to make any payment under Section 11.2(c)
on any date required hereunder shall not relieve any other Lender of its corresponding obligation
to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so
make its Loan or to make its payment under Section 11.2(c). The amounts payable by the
Borrower at any time hereunder and under the Notes to each Lender shall be a separate and
independent debt, and each Lender shall be entitled to protect and enforce its individual rights
arising out of this Agreement and the Notes independently of any other Lender, and it shall not be
necessary for any other Lender or either Agent to consent to, or be joined as an additional party
in, any proceedings to recover the payment of any overdue amounts.

     SECTION 2.5 Repayment. (a) Revolving Loans. The Borrower agrees to pay to
the Administrative Agent for the account of each Revolving Lender the full principal amount of the
outstanding Revolving Loans on the Final Maturity Date.

     (b) Tranche B Loans. The Borrower agrees to pay to the Administrative Agent for the
account of each Tranche B Lender the full principal amount of the Tranche B Loans in seven equal
consecutive quarterly installments, one payable on each Tranche B Principal Payment Date; provided
that on the Final Maturity Date the then aggregate unpaid principal amount of the outstanding
Tranche B Loans shall be paid in full.

     SECTION 2.6 Optional Prepayments. (a) The Borrower may, without penalty or premium
but subject to the indemnity provisions of Section 3.4, prepay all or a portion of the
Loans, upon at least three Business Days’ prior irrevocable notice to the Administrative Agent
specifying the Loans to be prepaid, their Tranche and their corresponding Borrowing Date and the
date and amount of the prepayment; provided that each partial prepayment of any Tranche shall be in
the minimum amount of US$5,000,000 or MXP$50,000,000 with respect to Dollar Loans or Tranche A2
Loans, respectively, and integral multiples of US$ 1,000,000 or MXP$10,000,000 in excess thereof
with respect to Dollar Loans or Tranche A2 Loans, respectively. Upon receipt of a notice of
prepayment, the Administrative Agent shall promptly give notice thereof to each Lender holding a
Loan to be prepaid. If such notice of prepayment is given by the Borrower, 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

Credit Agreement  25

 

accrued interest to, and any other amounts then due on, each
such date on the amount prepaid. Each optional prepayment shall be applied pro rata to the Loans
made on the Borrowing Date and under the Tranche being prepaid in accordance with Section
2.13(a) and (with respect to Tranche B Loans) to the installments of principal pro rata across
the remaining scheduled amortizations. Any Tranche B Loan prepaid may not be reborrowed.

     SECTION 2.7 Optional Reduction of Revolving Commitments. (a) The Borrower may from
time to time during the Tranche A Commitment Period, on at least three Business Days’ prior written
notice received by the Administrative Agent (which shall promptly give notice thereof to each
Tranche A 1 Lender or Tranche A2 Lender, as applicable), permanently reduce (i) the amount of the
Tranche Al Commitments to an amount not less than the aggregate principal amount of all outstanding
Tranche Al Loans (after giving effect to any payment or prepayment thereof) and/or (ii) the amount
of the Tranche A2 Commitments to an amount not less than the aggregate principal amount of all
outstanding Tranche A2 Loans (after giving effect to any payment or prepayment thereof). Any such
reduction of Tranche A l Commitments or Tranche A2 Commitments shall be in the minimum amount of
US$5,000,000 or MXP$50,000,000, respectively, and integral multiples of US$1,000,000 or
MXP$10,000,000, respectively, in excess thereof. The Borrower may at any time on like notice during
the Tranche A Commitment Period terminate the Tranche Al Commitments and/or the Tranche A2
Commitments, as the case may be, upon payment in full of the entire principal amount then
outstanding of the Tranche Al Loans and/or Tranche A2 Loans, as the case may be, together with all
accrued and unpaid interest thereon and all other amounts payable by the Borrower in connection
therewith.

     (b) All reductions of Revolving Commitments shall be pro rata among the Tranche A1 Lenders or
the Tranche A2 Lenders, as applicable, according to their Tranche A1 Revolving Percentages or
Tranche A2 Revolving Percentages, as applicable.

     SECTION 2.8 Mandatory Prepayments. (a) If on any date the Borrower or any its
Subsidiaries shall receive Net Cash Proceeds from any Prepayment Event, the Borrower shall
promptly, and in any event within ten Business Days, make a prepayment of the Loans in an aggregate
amount equal to 100% of such Net Cash Proceeds; provided that the Borrower shall not be required to
prepay the Loans as a result of a Prepayment Event under clause (a) or (b) of the
definition thereof if (and to the extent in excess of the Prepayment Threshold Amount), for any
fiscal year of the Borrower with respect to such Net Cash Proceeds received by the Borrower or any
of its Subsidiaries from any of the events described in clause (a) or (b),
respectively, of such definition that are in excess of US$ 1,000,000 (with amounts under each such
clause (a) and clause (b) being separately calculated as in excess of US$1,000,000
(each, the “Prepayment Threshold Amount”)), the Borrower shall have delivered to the Administrative
Agent a Reinvestment Notice prior to the date on which a prepayment would otherwise be required
under this Section 2.8(a). If the Borrower delivers a Reinvestment Notice pursuant to the
proviso to the immediately preceding sentence, such Net Cash Proceeds may be applied for the
purposes set forth in such Reinvestment Notice and, if not so applied by the Reinvestment
Prepayment Date with respect to the relevant Prepayment Event, shall be applied on such date to
prepay the loans in accordance with clause (c) below, until such outstanding Loans are
repaid in full.

Credit Agreement  26

 

     (b) Following the end of each fiscal year of the Borrower ended on or after December 31, 2006,
the Borrower shall prepay the Loans in an aggregate amount equal to 50% of Excess Cash Flow for
such fiscal year. Each prepayment pursuant to this clause (b) shall be made on or before
the date 30 days after the date on which financial statements are delivered pursuant to Section
6.2(a) with respect to the fiscal year for which Excess Cash Flow is being calculated (and in
any event within 120 days after the end of such fiscal year); provided that if the last day of a
Dollar Interest Period shall occur after the date such financial statements are so delivered but
prior to the date 30 days thereafter, the Borrower shall prepay the Loans on such last day of such
Dollar Interest Period.

     (c) Amounts to be applied in connection with prepayments made pursuant to clauses (a)
and (b) shall be applied (i) first to the Tranche B Loans in the inverse order of maturity
of the installments of principal thereof and (ii) second, once all amounts due under the Tranche B
Loans have been paid in full, to reduce permanently the Tranche Al Commitments and the Tranche A2
Commitments, pro rata. After giving effect to such Commitment reductions, if the aggregate amount
of Tranche Al Loans outstanding would exceed the then amount of the Tranche Al Commitments or if
the aggregate amount of Tranche A2 Loans outstanding would exceed the then amount of the Tranche A2
Commitments, the Borrower shall repay each such excess amount promptly (and, in any event, within
ten Business Days) after the event giving rise to such reduction of the Revolving Commitments.

     (d) Each prepayment of Loans under this Section 2.8 shall be made together with
accrued interest to the date of such prepayment on the amount so prepaid and any other amounts due
pursuant to Section 3.4. Any amount prepaid under this Section 2.8 may not be reborrowed.

     SECTION 2.9 Interest. (a) Dollar Loans. The Borrower shall pay to the
Administrative Agent for the account of each Dollar Lender interest on the unpaid principal amount
of the Dollar Loans for
each day during each Dollar Interest Period for each such Dollar Loan until the date on which
such Dollar Loans are paid in full at a rate per annum equal to Eurocurrency Rate determined for
such Dollar Interest Period plus the relevant Applicable Margin.

     (b) Tranche A2 Loans. The Borrower shall pay to the Administrative Agent for the
account of each Tranche A2 Lender interest on the unpaid principal amount of the Tranche A2 Loans
for each day during each Tranche A2 Interest Period for each such Tranche A2 Loan until the date on
which such Tranche A2 Loans are paid in full at a rate per annum equal to the THE Rate determined
for such Tranche A2 Interest Period plus the relevant Applicable Margin.

     (c) If all or a portion of (i) the principal amount of any Loan, (ii) any interest payable on
the principal amount of any Loan (to the extent permitted by Applicable Law) or (iii) any fee
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 the Default Rate
from the date of such non-payment until paid in full and shall be payable on demand.

     (d) Except as otherwise provided in clause (c), interest shall be payable in arrears
on (i) in the case of Dollar Loans, each Dollar Interest Payment Date for the applicable Dollar
Loan

Credit Agreement  27

 

or (ii) in the case of Tranche A2 Loans, each Tranche A2 Interest Payment Date for the
applicable Tranche A2 Loan.

     SECTION 2.10 Computation of Interest. (a) Interest in respect of the Loans shall be
calculated on the basis of a 360-day year for the actual days elapsed; provided that if interest
with respect to any Dollar Loan shall apply at the Base Rate in accordance with this Agreement,
such interest shall be calculated on the basis of a 365/366-day year for the actual days elapsed.
The Administrative Agent shall, as soon as practicable, notify the Borrower and the Lenders of each
determination of Eurocurrency Rate or the TILE Rate; provided 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 Lenders in the
absence of manifest error. The Administrative Agent shall, at the request of the Borrower or any
Lender, deliver to the Borrower or such Lender, as the case may be, a statement showing the
quotations used by the Administrative Agent in determining any interest rate pursuant to
Section 2.9(a) and (b).

     SECTION 2.11 Inability to Determine Interest Rate. (a) 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 the Eurocurrency Rate applicable pursuant to
Section 2.9(a), for any requested Dollar Interest Period, the Administrative Agent shall
forthwith give notice by facsimile of such determination to the Borrower and each Dollar Lender at
least one day prior to the last day of the current Dollar Interest Period. Thereafter, the
obligation of the Lenders to make or maintain Dollar Loans shall be suspended until the
Administrative Agent (upon the instruction of the
Majority Lenders) revokes such notice. Upon receipt of such notice, the Borrower may revoke
any pending request for the making or continuation of a Dollar Loan or, failing that, such Dollar
Loan requested or continued by the Borrower will bear interest at the Base Rate plus the Applicable
Margin.

     SECTION
2.12 Fees. (a) Administration Fee. The Borrower agrees to pay to
the Administrative Agent, for its account, all fees in such amount and in such manner as shall have
been agreed to by the Administrative Agent and the Borrower in a separate fee letter (the
“Administration Fee Letter”).

     (b) Arrangement Fees. The Borrower agrees to pay to Banc of America Securities LLC and
BBVA Securities Inc., for their account, all fees in such amount and in such manner as shall have
been agreed to among the Arrangers and the Borrower in a separate fee letter dated as of September
6, 2005 (the “Arrangement Fee Letter”).

     (c) Collateral Agency. The Borrower agrees to pay to the Collateral Agent, for its
account, all fees in such amount and in such manner as shall have been agreed to by the Collateral
Agent and the Borrower in a separate fee letter (the “Collateral Agency Fee Letter”).

     (d) Commitment Fee.(i) (i) The Borrower agrees to pay to the Administrative Agent, for
the account of each Revolving Lender with a Revolving Commitment, a commitment fee on the

Credit Agreement  28

 

daily
average unused portion of such Lender’s Tranche A1 Commitment and/or Tranche A2 Commitment for the
period from and including the Effective Date to but excluding the last day of the Tranche A
Commitment Period applicable to the Tranche Al Commitments or the Tranche A2 Commitments, as the
case may be (the “Commitment Fee”) at a rate per annum determined based on the aggregate level of
disbursements under Tranche Al Loans and the Dollar Equivalent of the disbursements under Tranche
A2 Loans in accordance with the table below:

	 	 	 	 	 
	Aggregate outstanding	 	 
	Revolving Loans	 	Commitment Fee Rate
	> US$20,000,000
	 	 	0.50	%
	3
US$10,000,000 to £ US$20,000,000
	 	 	0.75	%
	< US$10,000,000
	 	 	1.00	%

     (ii) The Commitment Fee shall be payable in arrears on each Commitment Fee Payment
Date, for the period then ending for which such Commitment Fee shall not have been
theretofore paid. The Commitment Fee shall be computed for the actual number of days elapsed
on the basis of a year of 360 days.

     SECTION 2.13 Pro Rata Treatment and Payments. (a) Except as otherwise provided
herein, (i) each payment by the Borrower on account of principal of the Loans shall be made pro
rata to the Lenders according to the respective outstanding principal amounts of the Loans then due
and payable, converting the amount of all Tranche A2 Loans for purposes of any such pro rata
calculations into Dollars
based on the Dollar Equivalent thereof, and (ii) each payment of interest on the Loans shall
be made for the account of the Lenders pro rata in accordance with the respective amounts of
interest on the Loans then due and payable to them.

     (b) Payments of principal and interest in respect of Dollar Loans and payments of fees shall
be made in Dollars. Payments of principal and interest in respect of Tranche A2 Loans shall be made
in Pesos, and payments of other amounts shall be made in Dollars. All payments to be made by the
Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or
set-off. Except as otherwise expressly provided herein, all payments by the Borrower hereunder
shall be made to the Administrative Agent, for the account of the respective Lenders to which such
payment is owed, at the applicable Administrative Agent’s Office and in immediately available
funds, and shall be made not later than 2:00 p.m., New York City time, on the date specified
herein. The Administrative Agent shall distribute such payments to the Lender or Lenders entitled
to receive the same promptly upon receipt in like funds as received. All payments received by the
Administrative Agent after 2:00 p.m., New York City time, shall be deemed received on the next
succeeding Business Day and any applicable interest or fee shall continue to accrue. If any payment
on a Loan becomes due and payable on a day other than a Business Day therefor, the maturity thereof
shall be extended to the next succeeding Business Day for such Loan (and such extension of time
shall be reflected in computing interest or fees, as the case may be) unless, with respect to
Dollar Loans, 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.

     (c) Unless the Administrative Agent shall have received notice from a Lender prior to the
proposed date of any Loan that such Lender will not make available to the Administrative

Credit Agreement  29

 

Agent such
Lender’s share of such Loan, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with Section 2.1 and may, in reliance upon such
assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has
not in fact made its share of the applicable Loan available to the Administrative Agent, then the
applicable Lender and the Borrower, upon receipt of notice from the Administrative Agent of such
failure, severally agree to pay to the Administrative Agent forthwith on demand such corresponding
amount in immediately available funds with interest thereon, for each day from and including the
date such amount is made available to the Borrower to but excluding the date of payment to the
Administrative Agent, at (i) in the case of a payment to be made by such Lender, the Overnight Rate
and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to the
Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the
same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the
amount of such interest paid by the Borrower for such period. If such Lender pays its share of the
applicable Commitment to the Administrative Agent, then the amount so paid shall constitute such
Lender’s Loan included in such Commitment. Any payment by the Borrower shall be without prejudice
to any claim the Borrower may have against a Lender that shall have failed to make such payment to
the Administrative Agent.

     (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the
date on which any payment is due to the Administrative Agent for the account of the Lenders
hereunder that the Borrower will not make such payment, the Administrative Agent may
assume that the Borrower has made such payment on such date in accordance herewith and may, in
reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the
Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to
the Administrative Agent forthwith on demand the amount so distributed to such Lender, in
immediately available funds with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the Administrative Agent, at
the Overnight Rate.

     (e) Except as otherwise set forth herein, all payments made under this Agreement or any other
Loan Document shall be applied first (in each case on a pro rata basis to the recipients thereof
based upon the amounts then owed to them) to pay fees and expenses due to the Beneficiaries under
the Loan Documents, then to pay accrued and unpaid interest on the Loans, then to pay principal of
the Loans and then to pay any and all other amounts payable to the Beneficiaries under the Loan
Documents.

     SECTION 2.14 Set-Off, Sharing of Payments, Etc. (a) Without limiting any of the
obligations of the Loan Parties or the rights of any Beneficiary under the Loan Documents, if the
Borrower shall fail to pay when due (whether at stated maturity, by acceleration or otherwise) any
amount payable by it hereunder or under any other Loan Document, then (to the extent not in
violation of an Applicable Law) each Beneficiary may, without prior notice to any Loan Party (which
notice is expressly waived by it to the fullest extent permitted by Applicable Law), set off and
appropriate and apply against such amount any and all deposits (general or special, time or demand,
provisional or final, in any currency, matured or unmatured) at any time held or any other
Indebtedness owing by such Beneficiary or any of its Affiliates (in each case, including any branch
or agency thereof) to or for the credit or account of the Borrower or any other Loan Party.

Credit Agreement  30

 

Each
Beneficiary shall promptly provide written notice of any such set-off by it to the Borrower and the
Administrative Agent; provided that failure by such Beneficiary to provide such notice shall not
give the Borrower any cause of action or right to damages or affect the validity of such set-off
and application.

     (b) If, other than as expressly provided elsewhere herein, any Beneficiary shall obtain on
account of the Obligations owing to it hereunder or in respect of its Loans any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or otherwise) in excess of
its share of payments on account of the Obligations obtained by all the Beneficiaries, such
Beneficiary shall forthwith (i) notify the Administrative Agent of such fact, and (ii) purchase
from the other Beneficiaries such participations in such amounts made by them as shall be necessary
to cause such purchasing Beneficiary to share the excess payment ratably with each of them;
provided, that if all or any portion of such excess payment is thereafter recovered from the
purchasing Beneficiary, such purchase shall to that extent be rescinded and each other Beneficiary
shall repay to the purchasing Beneficiary the purchase price paid therefor, without interest. The
provisions of this Section 2.14(b) shall not be construed to apply to (A) any payment made
by the Borrower pursuant to and in accordance with the express terms of this Agreement or (B) any
payment obtained by a Lender as consideration for the assignment of or sale of a participation in
any of its Loans. 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 2.14 and will in each case notify the Lenders and the
Borrower following any such purchases.

     Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so
under Applicable Law, that any Beneficiary acquiring a participation pursuant to the foregoing
arrangements may exercise against such Loan Party rights of setoff permitted hereunder and
counterclaim with respect to such participation as fully as if such Beneficiary were a direct
creditor of such Loan Party in the amount of such participation.

ARTICLE III.

YIELD PROTECTION, ETC.

     SECTION 3.1 Taxes. (a) All payments made by each Loan Party 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 Taxes, including Other Taxes (but excluding any tax imposed on or measured by the
net income or net profits or capital (or any franchise or similar tax imposed in lieu thereof) of a
beneficiary of such payment (each a “Payee”) pursuant to the laws of the jurisdiction (or any
political subdivision thereof) in which it is organized or the jurisdiction (or any political
subdivision thereof) in which the Lending Office of such Lender is located and any withholding
taxes to the extent imposed by reason of any Payee, that is not a Mexican Financial Institution, or
its assignees or participants, if any, failing to make reasonable commercial efforts, consisting of
timely making any necessary filing and taking related action, to maintain its registration for the
purposes of Article 195(1) or Article 196(11) of the Mexican Income Tax Law (Ley del Impuesto Sobre
la Renta) or any successor provision with Hacienda (collectively, the “Excluded Taxes”)). If any
such Taxes that are not Excluded Taxes (“Non-Excluded Taxes”) are required to be withheld from any
amounts payable to any Payee hereunder (subject to the right of such Loan Party to contest any such
requirement in good faith, so long as

Credit Agreement  31

 

proper reserves are maintained and each Payee hereunder is
paid the full amounts payable hereunder including any additional amounts payable), such Loan Party
shall pay such Non-Excluded Taxes, including Other 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,
Other Taxes and Additional Amounts, including any of the foregoing levied on Additional Amounts)
interest or any such other amounts payable hereunder at the rates or in the amounts specified in
this Agreement in the absence of such payments or deductions; provided that no such Additional
Amounts shall be payable in respect of any Taxes that would not have been imposed but for a failure
by a Payee to provide the documents required by Section 3.1(c) strictly pursuant to the
terms of, and only in the circumstances specified in, Section 3.1(c), in excess of the
Additional Amounts that would have been payable had such documents been provided. In addition, such
Loan Party shall pay any Other Taxes to the relevant Governmental Authority in accordance with
Applicable Law. Whenever any Non-Excluded Tax or Other Tax is payable by a Loan Party, as promptly
as possible thereafter, such Loan Party shall send to the Administrative Agent, for the account of
such Payee, a certified copy by a Responsible Officer of such Loan Party of a stamped filed receipt
showing payment thereof or such other document reasonably satisfactory to such Payee showing
payment thereof. If such Loan Party fails to pay any Non-Excluded Taxes or Other
Taxes when due to the appropriate taxing authority or fails to remit to the Administrative
Agent the required receipts or other required documentary evidence, such Loan Party shall indemnify
the affected Payee for any incremental taxes, interest, penalties, loss, liability, claim or
expense (including legal fees and expenses) 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.

     (b) Each Loan Party shall indemnify the Administrative Agent and each Payee, within 10 days
after written demand therefor, for the full amount of any Non-Excluded Taxes or Other Taxes paid by
the Administrative Agent or such Payee on or with respect to any payment by or on account of any
obligation of such Loan Party hereunder (including Non-Excluded Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section) and any penalties, interest and
reasonable expenses arising therefrom or with respect thereto, whether or not such Non-Excluded
Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental
Authority. A certificate as to the amount of such payment or liability delivered to such Loan Party
by a Payee, or by the Administrative Agent on its own behalf or on behalf of a Payee, shall be
conclusive absent manifest error.

     (c) Each Payee that is not a Mexican Financial Institution 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 required under Applicable Law as may be required to
establish any available exemption from, or reduction in the amount of, otherwise applicable
Non-Excluded Taxes; provided that (i) such documentation is consistent with Applicable Law and (ii)
such documentation would not, in the judgment of such Payee, require such Payee to disclose any
confidential or proprietary information or otherwise be disadvantageous to such Payee; provided
that a documentation shall not be considered disadvantageous solely by virtue of administrative
inconvenience to such Payee. The Borrower and the Administrative Agent shall be entitled to rely
upon the accuracy of any such documentation furnished to it by any Payee that is not a Mexican
Financial Institution and shall

Credit Agreement  32

 

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 3.2 Illegality. Notwithstanding any other provisions herein, if any Applicable
Law or any change therein or in the interpretation or application thereof shall make it unlawful
for any Lender to make or maintain a Loan as contemplated by this Agreement, then such Lender may
give notice thereof to each of the Borrower and the Administrative Agent and, upon the giving of
such notice (a) the Commitments of such Lender hereunder to make further Loans shall forthwith be
canceled (with, unless the Borrower replaces such Lender in accordance with Section 3.6
within ten Business Days following such notice, a corresponding reduction of the aggregate amount
of the Commitments under the Tranche of the canceled Commitment) and/or (b) if such Applicable Law
shall so mandate, such Lender’s Loan shall be prepaid in full by the Borrower, together with
accrued and unpaid interest thereon and all other amounts payable by the Borrower under this
Agreement, on or before such date as shall be mandated by such Applicable Law (such prepayment not
being shared as described in Section 2.13 with any Lenders not so affected);
provided that if it is lawful for such Lender to maintain its Loan through the last day of the
then current Dollar Interest Period or Tranche A2 Interest Period, as the case may be, such payment
shall be made on such date.

     SECTION 3.3 Additional Costs. (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 Lender (or any corporation Controlling such Lender) including those relating to taxation,
reserves, special deposit, cash ratio, liquidity, capital adequacy or Eurocurrency Liabilities, if
applicable 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 Lender of maintaining its Loans is increased by an amount
determined by such Lender to be material; or

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

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

Credit Agreement  33

 

     (A) such Lender or the Administrative Agent (an “Affected Party”) 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) within a reasonable period (not exceeding 15 Business Days) following any
demand from time to time by such Affected Party through the Administrative Agent
(with a copy contemporaneously sent to the Borrower), the Borrower shall pay to the
Administrative Agent, for the account of such Affected Party, such amount as shall
compensate such Affected Party for such increased cost, reduced amount receivable or
reduction in rate of return (excluding anticipated profits unrelated to those
measured by the Applicable Margin, the Default Rate, if applicable, and the
Commitment Fee). The certificate of such Affected Party specifying the amount of
such compensation shall be conclusive save in the case of manifest error.

     (b) If an Affected Party shall request compensation under this Section 3.3, such
Affected Party 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 3.3 shall survive the
termination of this Agreement and the payment of the outstanding Loans. Failure or delay on the
part of any Affected Party to demand compensation pursuant to this Section 3.3 shall not
constitute a waiver of such Affected Party’s right to demand compensation; provided that the
Borrower shall not be required to compensate an Affected Party, as applicable, pursuant to this
Section 3.3 for any increased costs or reductions incurred more than 180 days prior to the
date that such Affected Party notifies the Borrower of the event giving rise to such increased
costs or reductions and of such Affected Party’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 3.4 Funding Losses. The Borrower agrees to indemnify each Lender and to hold such
Lender harmless from any actual loss or expense (excluding loss of profit) which such Lender 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 Loans of such Lender, (b)
default by the Borrower in making a borrowing of Loans or any prepayment after the Borrower has
given a notice in accordance with Section 2.3 or 22-6 and (c) the making by the Borrower of
a prepayment of the Loans on a day which is not the last day of a Dollar Interest Period (with
respect to Dollar Loans) or Tranche A2 Interest Period (with respect to Tranche A2 Loans) (whether
or not the Administrative Agent or such Lender has previously consented to such prepayment),
including any such loss or expense arising from interest or fees payable by such Lender to lenders
of funds obtained by it in order to maintain its Loans hereunder as set forth in a certificate of
such Lender delivered to the Borrower through the Administrative Agent. This covenant shall survive
termination of this Agreement and payment of the Loans.

Credit Agreement  34

 

     SECTION 3.5 Change of Lending Office. Each Lender that is not a Mexican Financial
Institution agrees that, upon the occurrence of any event giving rise to the operation of
Section 3.1(a) (other than the imposition of the Mexican withholding taxes expected, based
upon the identity and place of residence of each Lender on the Effective Date, or the Mexican
withholding taxes applicable to interest payments made to an Eligible Assignee), 33.22 or 31(a) as
to it and upon request by the Borrower, it will use its commercially reasonable efforts to avoid or
minimize the consequences of such event if such action shall not, in the judgment of such Lender,
as the case may be, be illegal or economically or otherwise disadvantageous to it. If such Lender
is entitled to compensation for the events specified under Section 3.1 (other than as set
forth in the preceding sentence) or 31(a), or the Borrower is required to make a prepayment as a
result of the operation of Section 3.2, such Lender shall use commercially reasonable
efforts for a period of 30 days to designate a different Lending Office for any Obligation affected
by such event if such designation will avoid the need for, or reduce the amount of, such
compensation (except as set forth in the preceding sentence)
and will not, in the sole opinion of such Lender, result in any economic, legal or regulatory or
other disadvantage to such Lender or any of its Affiliates.

     SECTION 3.6 Replacement of Lenders. The Borrower shall be permitted, at its sole expense
and effort, to replace with a replacement financial institution or Eligible Assignee any Lender (a)
that requests reimbursement for amounts owing pursuant to Section 3.1(a) (but only if such
Lender is (i) not a Mexican Financial Institution and (ii) a financial institution not registered
with Hacienda for purposes of Article 195(1) or Article 196(11) of the Mexican Income Tax Law (Ley
del Impuesto Sobre la Renta) or any successor provision thereof and not a resident of (or, if
acting through a branch or agency, does not have its principal office in) a country with which
Mexico has entered into a treaty for the avoidance of double taxation) or 11W, (b) to which the
Borrower is required to make a prepayment or commitment reduction as a result of the operation of
Section 3.2, (c) that defaults in its obligation to make its Loan hereunder or (d) that
fails to consent to an election, consent, amendment, waiver or other modification to this Agreement
or other Loan Document requiring more Lenders than the Majority Lenders’ consent and such election,
consent, amendment, waiver or other modification is otherwise consented to by Lenders holding more
than 66 2/3% of the sum of (i) all undrawn Commitments on such date and (ii) all Loans outstanding
on such date, as determined by the Administrative Agent by converting Tranche A2 Loans into Dollars
based on the Dollar Equivalent thereof without giving effect to the Loans and undrawn Commitments
attributable to such Lender; provided that (A) such replacement does not conflict with any
Applicable Law, (B) no Default or Event of Default shall have occurred and be continuing at the
time of such replacement, (C) prior to any such replacement, such Lender shall have taken no action
under Section 3.5 which has eliminated the continued need for payment of amounts owing
pursuant to Section 3.1(a) or 31(a) or the operation of Section 3.2, (D) the
replacement financial institution shall purchase, at par, the Loans and other amounts (including
accrued and unpaid interest) owing to such replaced Lender on or prior to the date of replacement,
(E) the Borrower shall be liable to such replaced Lender under Section 3.4 if the Loans
owing to such replaced Lender shall be purchased other than on the last day of a Dollar Interest
Period or Tranche A2 Interest Period, as the case may be, relating to such Loans, (F) the
replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the
Administrative Agent, (G) the replaced Lender shall be obligated to make such replacement without
recourse in accordance with the provisions of Section 11.8 (provided that the Borrower
shall be obligated to pay the registration and processing fee referred

Credit Agreement  35

 

to therein), (H) until such
time as such replacement shall be consummated, the Borrower shall pay all additional amounts (if
any) required pursuant to Section 3.1 (a) or 3d(a), as the case may be, and (I) any such
replacement shall not be deemed to be a waiver of any rights that the Borrower, either Agent or any
other Lender shall have against the replaced Lender.

Credit Agreement  38

 

the
business in which it is engaged and is duly qualified or licensed as a foreign corporation in each
jurisdiction in which such qualification or license is required, unless failure so to have such
power and authority or to qualify or be licensed could not reasonably be expected to have a
Material Adverse Effect.

     SECTION 5.2 Corporate Power and Authority; Enforceable Obligations. (a) Each Loan
Party has the corporate power to execute, deliver and perform the terms and provisions of the Loan
Documents to which it is a party, and has taken all necessary corporate action required by its

performance by each Loan Party of the Loan Documents to which it is a party in accordance with
their respective terms, nor the consummation of the transactions herein or therein contemplated,

(b) will contravene any Applicable Law to which such Loan Party is subject or any judgment, decree,
order or permit applicable to such Loan Party, or (c) will conflict with or will result in any

statements and the results of their operations for the periods therein stated and have been
prepared in accordance with IFRS (with respect to the financial statements dated December 31, 2004)
and with GAAP (with respect to the financial statements for the six months ended June 30, 2005),
consistently applied throughout the periods involved (unless and to the extent otherwise stated
therein).

     (b) Except as disclosed in this Agreement or in the Financial Statements, there are no
liabilities or obligations with respect to the Borrower and its Subsidiaries of any nature
whatsoever (whether absolute, accrued, contingent or otherwise and whether or not due) and the
Borrower is not aware of any basis for the assertion against it or its Subsidiaries of any
liability or obligation of any nature that is not fully disclosed in the Financial Statements
which, in either case, either individually or in the aggregate, could reasonably be expected to
have a Material Adverse Effect.

     (c) Since December 31, 2004, there has been no development or event that has had or could
reasonably be expected to have a Material Adverse Effect.

     SECTION 5.7 Taxes, Assessments and Fees. Each Loan Party has timely filed all tax returns
and reports required to have been filed and has paid all taxes due by it except such taxes as are
being contested in good faith by appropriate proceedings for which adequate (in the good faith
judgment of such Loan Party) reserves have been made (in accordance with GAAP) or such taxes the

Investment Company Act of 1940, as amended.

Credit Agreement  40

 

     SECTION 5.9 Accuracy of Information. All written information supplied by the Loan Parties
to the Arrangers, either Agent and/or the Lenders relating to the Loan Parties, taken as a whole,
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 taken as a whole, 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. It is understood that: (a) no representation or warranty
is made concerning the forecasts, estimates, pro forma information, projections and statements as
to anticipated future performance or conditions, and the assumptions on which they were based,
contained in any such information, reports, financial statements, exhibits or schedules, except
that as of the date such forecasts, estimates, pro forma information, projections and statements
were generated, (i) such forecasts, estimates, pro forma information, projections and statements
were based on the good faith assumptions of the management of the Borrower and (ii) such
assumptions were believed by such management to be reasonable and (b) such forecasts, estimates,
pro forma information and statements, and the assumption on which they were based, may or may not
prove to be correct.

hereunder and under the other Loan Documents to which it is a party are and will at all times be
unconditional general obligations of such Loan Party, and rank and will at all times rank at least

obligations accorded preference by mandatory provisions of law. There is no Lien upon or with
respect to any of the present Property or Indebtedness of any Loan Party or its respective
Subsidiaries other than Liens permitted or required by this Agreement, including, without
limitation, Permitted Liens.

deduction, charge or withholding imposed, levied or made by or in Mexico or any political
subdivision or taxing authority thereof or therein either (a) on or by virtue of the execution or
delivery of the Loan Documents or (b) on any payment to be made pursuant to the Loan Documents to
any Person, except that payments of interest under this Agreement or the Notes and fees payable
hereunder and under the Fee Letters
will be subject to a Mexican withholding tax at a rate of 4.9% so long as the Payee, that is not a
Mexican Financial Institution, (i) is a foreign commercial bank or other financial institution
registered with Hacienda for purposes of Article 195(I) of the Mexican Income Tax Law (Ley del
Impuesto Sobre la Renta), the regulations thereunder and any administrative rules issued thereunder
and (ii) is a resident for tax purposes of (or its principal place of business, if lending through
a branch or agency, is located in) a country with which Mexico has entered into a treaty for the
avoidance of double taxation. As of the Effective Date, each Loan Party is permitted under
Applicable Law, to make

Credit Agreement  41

 

all payments pursuant to the Loan Documents free and clear of all Taxes
imposed, levied or made by or in Mexico or any political subdivision or taxing authority thereof,
as provided in each Loan Document, without any liability to be borne by the payee in connection
with such Mexican withholding tax to the extent that the Loan Party making such payment has
complied with its obligations in Section 3.1 of this Agreement to pay to the appropriate
Mexican authorities applicable Taxes required to be paid by such Loan Party.

     SECTION 5.13 Proper Form. The Loan Documents are (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 each Loan Party; provided that, if any legal proceedings are brought in a court
of Mexico for the enforcement against a Loan Party, of this Agreement, the Fee Letters or any other
Loan Document, a Spanish translation of such document prepared by a translator approved by the
Mexican court would have to be approved by such court after such Loan Party 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, the Fee Letters or any other Loan Document in
Mexico it is not necessary that this Agreement, the Fee Letters or any other Loan 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, the Fee Letters or any other Loan Document;
provided that the Arrendadora Pledges must be executed before a Mexican Public Notary and
registered as described in Section 6.11.

     SECTION 5.14 Choice of Law. In any action or proceeding involving a Loan Party arising out
of or relating to any Loan Document in any court of Mexico, the Lenders and the Agents would be
entitled to the recognition and effectiveness of the choice of law provisions of Section
11.4.

     SECTION 5.15 Immunity. Each Loan Party is subject to suit in Mexico and neither any Loan
Party 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 any Loan Document,
and to the extent that such Loan Party or its Property may have or may hereafter become entitled to
any such right of immunity it has effectively waived such right under Section 11.13;
provided that the Concession Title may not be transferred to any Person without the prior consent
of Mexico. The
waiver by each Loan Party 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 any Loan Document may be commenced. The performance of the Loan
Documents by the Loan Parties constitutes private and commercial acts rather than governmental or
public acts.

     SECTION 5.16 Status of Concession. The Concession Title is in full force and effect and no
proceeding or, to the best knowledge of the Borrower, investigation seeking the termination or
revocation of the Concession Title has been initiated pursuant to a notice sent to the Borrower.

interests in, all its real and personal property material to its business, except for (i) minor

be expected to have a Material Adverse Effect and (ii) title to the locomotives covered by the
Supplemental Arrendadora Pledge, which is subject to the outcome of the Arrendadora Internacional
Litigation.

     (b) Each Loan Party owns, or is licensed to use, all trademarks, tradenames, copyrights,

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.

     (c) As of the Effective Date, each Loan Party maintains insurance with respect to all Property
material to the conduct of its business and Schedule 5.17(c) contains an accurate description of
such insurance coverage, insured amounts and the name of each insurance company with which each
such insurance is maintained.

     SECTION 5.18 Subsidiaries. The Subsidiaries listed on Schedule 5.18 hereto constitute the
only Subsidiaries of each Loan Party as at the Effective Date.

     SECTION 5.19 Federal Regulations. No part of the proceeds of any 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 of Governors of the Federal Reserve System.
If requested by any Lender or Agent, the Borrower will furnish to the Agents and each Lender 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.

Arrendadora Pledges, each of the Arrendadora Pledges creates a valid, enforceable and, when the
requirements set forth in Section 6.11 have been satisfied, perfected, security interest in
the collateral purported to be covered thereby in favor of the Collateral Agent, acting on behalf
and for the benefit of the Beneficiaries; provided that the Supplemental Arrendadora Pledge is
subject to the outcome of the Arrendadora Internacional Litigation in respect of collateral covered
by the Supplemental Arrendadora Pledge to the extent that, until the parties to such litigation
have reached an agreement or a judgment in connection with such litigation has been obtained and
complied with, title to such collateral will not be clearly vested in Arrendadora. The Liens
created by each of the Arrendadora Pledges are enforceable as security for the obligations

Credit Agreement  43

 

secured
thereunder in accordance with their respective terms and (with respect to the Supplemental
Arrendadora Pledge) subject to the outcome of the Arrendadora Internacional Litigation.

not merely as surety and with respect to all such Obligations howsoever created, arising or

     (g) any other act or omission to act or delay of any kind by any Loan Party, either Agent or

Guarantee may apply, (ii) all notices that may be required by Applicable Law or otherwise to
preserve intact any rights of any Beneficiary against any Loan Party, including any demand,

any right, power, privilege or remedy conferred upon such Person under the Loan Documents or
otherwise, (iv) any requirement that any Beneficiary exhaust any right, power, privilege or remedy,
or exhaust or apply any assets of the Borrower or any other Guarantor or mitigate any damages
resulting from a default, under any Loan Document, or proceed to take any action against any
collateral granted pursuant to the Loan Documents, or against any Loan Party or any other Person

ARTICLE X.

THE AGENTS

     SECTION 10.1 Appointment and Authority. Each of the Lenders hereby irrevocably appoints Bank of America
to act on its behalf as the Administrative Agent and each of the Lenders and (in its capacity as
Beneficiary) the Administrative Agent hereby irrevocably appoints BBVA Bancomer as the Collateral
Agent, in each case hereunder and under the other Loan Documents and authorizes each Agent to take
such actions on its behalf and to exercise such powers as are delegated to such Agent by the terms
hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The
provisions of this Article are solely for the benefit of the Agents and the Lenders, and neither
the Borrower nor any other Loan Party shall have rights as a third party beneficiary of any of such
provisions.

     SECTION 10.2 Rights as a Lender. Each Person serving as an Agent hereunder shall have the same rights
and powers in its capacity as a Lender as any other Lender and may exercise the same as though it
were not an Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or
unless the context otherwise requires, include each Person serving as Agent hereunder in its
individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as
the financial advisor or in any other advisory capacity for and generally engage in any kind of
business with any Loan Party or any Subsidiary or other Affiliate thereof as if such Person were
not an Agent hereunder and without any duty to account therefor to the Lenders.

     SECTION 10.3 Exculpatory Provisions. The Agents shall not have any duties or obligations except those
expressly set forth herein and in the other Loan Documents. Without limiting the generality of the
foregoing, neither Agent:

     (a) shall be subject to any fiduciary or other implied duties, regardless of whether a Default
has occurred and is continuing;

     (b) shall have any duty to take any discretionary action or exercise any discretionary powers,
except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents
that such Agent is required to exercise as directed in writing by the Majority Lenders (or such
other number or percentage of the Lenders as shall be expressly provided for herein or in the other
Loan Documents); provided that neither Agent shall be required to take any action that, in its
opinion or the opinion of its counsel, may expose such Agent to liability or that is contrary to
any Loan Document or Applicable Law; and

Credit Agreement 61

 

     (c) shall, except as expressly set forth herein and in the other Loan Documents, have any duty
to disclose, or be liable for the failure to disclose, any information relating to any of the Loan
Parties or any of their respective Affiliates that is communicated to or obtained by the Person
serving as Agent or any of its Affiliates in any capacity.

     Neither Agent shall be liable for any action taken or not taken by it (i) with the consent or
at the request of the Majority Lenders (or such other number or percentage of the Lenders as shall
be necessary, or as such Agent shall believe in good faith shall be necessary, under the
circumstances as provided in Sections 8.2 and 11.3) or (ii) in the absence of its
own gross negligence or willful misconduct. Neither Agent shall be deemed to have knowledge of any
Default unless and until notice describing such Default is given to such Agent by a Loan Party or a
Lender.

     Neither Agent shall be responsible for or have any duty to ascertain or inquire into (i) any
statement, warranty or representation made in or in connection with this Agreement or any other
Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder
or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of
the covenants, agreements or other terms or conditions set forth herein or therein or the
occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this
Agreement, any other Loan Document or any other agreement, instrument or document or (v) the
satisfaction of any condition set forth in Article IV or elsewhere herein, other than to
confirm receipt of items expressly required to be delivered to the Administrative Agent.

     SECTION 10.4 Reliance by the Agents. Each Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent, statement, instrument,
document or other writing (including any electronic message, Internet or intranet website posting
or other distribution) believed by it to be genuine and to have been signed, sent or otherwise
authenticated by the proper Person. Each Agent also may rely upon any statement made to it orally
or by telephone and believed by it to have been made by the proper Person, and shall not incur any
liability for relying thereon. In determining compliance with any condition hereunder to the making
of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative
Agent may presume that such condition is satisfactory to such Lender unless the Administrative
Agent shall have received notice to the contrary from such Lender prior to the making of such Loan.
Each Agent may consult with legal counsel (who may be counsel for any Loan Party), independent
accountants and other experts selected by it, and shall not be liable for any action taken or not
taken by it in accordance with the advice of any such counsel, accountants or experts.

     SECTION 10.5 Delegation of Duties. Each Agent may perform any and all of its duties and exercise its
rights and powers hereunder or under any other Loan Document by or through any one or more
sub-agents appointed by such Agent. Each Agent and any such sub-agent may perform any and all of
its duties and exercise its rights and powers by or through their respective Related Parties. The
exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties
of such Agent and any such sub-agent, and shall apply to their respective activities in connection
with the syndication of the credit facilities provided for herein as well as activities as Agent.

Credit Agreement 62

 

     SECTION 10.6 Resignation of an Agent. Each Agent may at any time give notice of its resignation to the
Lenders and the Borrower. Upon receipt of any such notice of resignation, the Majority Lenders
shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a
bank with an office (or a subsidiary) in the United States, or an Affiliate of any such bank with
an office (or a subsidiary) in the United States. If no such successor shall have been so appointed
by the Majority Lenders and shall have accepted such appointment within 30 days after the
retiring Agent gives notice of its resignation, then the retiring Agent may on behalf of the
Lenders or (if the Collateral Agent, the Beneficiaries) appoint a successor Agent meeting the
qualifications set forth above; provided that if such Agent shall notify the Borrower and the
Lenders that no qualifying Person has accepted such appointment, then such resignation shall
nonetheless become effective in accordance with such notice and (a) the retiring Agent shall be
discharged from its duties and obligations hereunder and under the other Loan Documents (except
that in the case of any collateral security held by the Collateral Agent on behalf of the
Beneficiaries under any of the Loan Documents, the retiring Collateral Agent shall continue to hold
such collateral security until such time as a successor Collateral Agent is appointed) and (b) all
payments, communications and determinations provided to be made by, to or through such Agent shall
instead be made by or to each Lender directly, until such time as the Majority Lenders appoint a
successor Agent as provided for above in this Section. Upon the acceptance of a successor’s
appointment as Agent hereunder, such successor shall succeed to and become vested with all of the
rights, powers, privileges and duties of the retiring (or retired) Agent, and the retiring Agent
shall be discharged from all of its duties and obligations hereunder or under the other Loan
Documents (if not already discharged therefrom as provided above in this Section). The fees payable
by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless
otherwise agreed between the Borrower and such successor. After the retiring Agent’s resignation
hereunder and under the other Loan Documents, the provisions of this Article and Section
11.2 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be taken by any of them
while the retiring Agent was acting as Agent.

     SECTION 10.7 Non-Reliance on Agents and Other Lenders. Each Lender acknowledges that it has,
independently and without reliance upon either Agent or any other Lender or any of their Related
Parties and based on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon either Agent or any other Lender or any of their
Related Parties and based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action under or based upon
this Agreement, any other Loan Document or any related agreement or any document furnished
hereunder or thereunder.

     SECTION 10.8 No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of the
Arrangers shall have any powers, duties or responsibilities under this Agreement or any of the
other Loan Documents, except in its capacity, as applicable, as an Agent or a Lender.

     SECTION 10.9 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, concurso mercantil, quiebra, arrangement,
adjustment, composition or other judicial proceeding relative to any Loan Party, the Administrative
Agent (irrespective of whether the principal of any Loan

Credit Agreement 63

 

shall then be due and payable as herein
expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall
have made the demand on the Borrower) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

     (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans, and all other Obligations that are owing and unpaid and to file
such other documents as may be necessary or advisable in order to have the claims of the
Beneficiaries (including any claim for the reasonable compensation, expenses, disbursements
and advances of the Beneficiaries and their respective agents and counsel and all other amounts due
to the Beneficiaries under Sections 2.12 and 11.2) allowed in such judicial
proceeding; and

     (b) to collect and receive any monies or other property payable or deliverable on any such
claims and to distribute the same;

     and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Beneficiary to make such payments to
the Administrative Agent and, in the event that the Administrative Agent shall consent to the
making of such payments directly to the Beneficiaries, to pay to the Administrative Agent any
amount due for the reasonable compensation, expenses, disbursements and advances of the
Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent
under Sections 2.12 and 11.2.

     Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or
consent to or accept or adopt on behalf of any Lender any plan of reorganization, concurso
mercantil, quiebra, arrangement, adjustment or composition affecting the Obligations or the rights
of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any
Lender in any such proceeding.

     SECTION 10.10 Collateral and Guarantee Matters. The Beneficiaries irrevocably authorize the Collateral
Agent, at its option and in its discretion, to release any Lien on any Property granted to or held
by the Collateral Agent under any Loan Document (i) upon termination of the Commitments and payment
in full of all Obligations (other than contingent indemnification obligations), (ii) that is sold
or to be sold as part of or in connection with any sale permitted hereunder or under any other Loan
Document, or (iii) subject to Section 11.3, if approved, authorized or ratified in writing
by the Majority Lenders.

     Upon request by the Administrative Agent or (if the Majority Lenders shall so agree) the
Borrower at any time, the Majority Lenders will confirm in writing the Collateral Agent’s authority
to release its interest in particular types or items of Property pursuant to this Section
10.10.

     (b) Indemnification. Each Loan Party agrees, jointly and severally, to indemnify each
Agent (and any sub-agent thereof) and each Lender, and each Related Party of any of the foregoing
Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless
from, any and all losses, claims, damages, liabilities and related expenses (including the fees,
charges and disbursements of any counsel for any Indemnitee and of attorneys who may be employees
of any Indemnitee), incurred by any Indemnitee or asserted against any Indemnitee by any third

or proposed use of the proceeds thereof, (iii) any actual or alleged presence or release of
Hazardous Materials on or from any property owned or operated by any Loan Party or any of its
Subsidiaries, or any Environmental Liability related in any way to any Loan Party or any of its
Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other theory, whether
brought by a third party or by the Borrower or any other Loan Party (or any of their respective
Related Parties), and regardless of whether any Indemnitee is a party thereto, in all cases,
whether or not caused by or arising, in whole or in part, out of the comparative, contributory or
sole negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or related expenses (A) are
determined by a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or willful misconduct of such Indemnitee or (B) result from a
claim brought by the Borrower or any other Loan Party against an Indemnitee for breach in bad faith
of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower or
such

Credit Agreement 65

 

other Loan Party has obtained a final and nonappealable judgment in its favor on such claim as
determined by a court of competent jurisdiction.

     (c) Reimbursement by Lenders. To the extent that any Loan Party for any reason fails
to indefeasibly pay any amount required under clause (a) or (b) of this Section to
be paid by it to either Agent (or any sub-agent thereof) or any Related Party of either Agent, each
Lender severally agrees to pay to such Agent (or any such sub-agent) or such Related Party, as the
case may be, such Lender’s ratable share (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the
unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case
may be, was incurred by or asserted against such Agent (or any such sub-agent) in its capacity as
such, or against any Related Party of such Agent acting for such Agent (or any such sub-agent) in
connection with such capacity. The obligations of the Lenders under this clause (c) are
subject to the provisions of Section 2.4.

     (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by
Applicable Law, no Loan Party shall assert, and each Loan Party hereby waives, any claim against
any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive
damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the
transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof. No
Indemnitee referred to in clause (b) above shall be liable for any damages arising from the
use by unintended recipients of any information or other materials distributed by it through
telecommunications, electronic or other information transmission systems in connection with this
Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

     (e) Payments. All amounts due under this Section 11.2 shall be payable not

Agent, the replacement of any Lender, the termination of the Commitments and the repayment,
satisfaction or discharge of all the other Obligations.

     SECTION 11.3 Amendments and Waivers, Etc. No amendment or waiver of any provision of this Agreement or
any other Loan Document, and no consent to any departure by the Borrower or any other Loan Party
therefrom, shall be effective unless in writing signed by the Majority Lenders and the Borrower or
the applicable Loan Party, as the case may be, and acknowledged by the Administrative Agent, and
each such waiver or consent shall be effective only in the specific instance and for the specific
purpose for which given; provided that no such amendment, waiver or consent shall:

     (a) waive any condition set forth in Section 4.1(a) without the written consent of
each Lender;

     (b) extend or increase the Commitment of any Lender (or reinstate any Commitment terminated
pursuant to Section 8.2) without the written consent of such Lender;

Credit Agreement 66

 

     (c) postpone any date fixed by this Agreement or any other Loan Document for any payment or
mandatory prepayment of principal, interest, fees or other amounts due to the Lenders (or any of
them) hereunder or under any other Loan Document without the written consent of each Lender
directly affected thereby;

     (d) reduce the principal of, or the rate of interest specified herein on, any Loan or (subject
to clause (ii) of the second provision to this Section 11.3) any fees or other
amounts payable hereunder or under any Note, or change the manner of computation of any financial
ratio (including any change in any applicable defined term) used in determining the Applicable
Margin that would result in a reduction of any interest rate on any Loan or any fee payable
hereunder without the written consent of each Lender directly affected thereby; provided that
only the consent of the Majority Lenders shall be necessary to amend the definition of
“Default Rate” or to waive any obligation of the Borrower to pay interest at the Default Rate;

     (e) change Section 2.13 in a manner that would alter the pro rata sharing of payments
required thereby without the written consent of each Lender;

     (f) change any provision of this Section, the definition of “Majority Lenders” or “Tranche

required to amend, waive or otherwise modify any rights hereunder or make any determination or
grant any consent hereunder without the written consent of each Lender;

     (g) release any Guarantor from its Guarantee hereunder without the written consent of each
Lender; or

     (h) release all or substantially all of the Property pledged under the Arrendadora Pledges in
any transaction or series of related transactions without the written consent of each Lender;

and, provided further that (i) no amendment, waiver or consent shall, unless in writing and signed
by the relevant Agent in addition to the Lenders required above, affect the rights or duties of
such Agent under this Agreement or any other Loan Document; and (ii) the Fee Letters may be
amended, or rights or privileges thereunder waived, in a writing executed only by the parties
thereto. Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right
to approve or disapprove any amendment, waiver or consent hereunder, except that the Commitment of
such Lender may not be increased or extended without the consent of such Lender.

OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT OF THIRD PARTY RIGHTS OR
FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH THE

Lender or any other Person for losses, claims, damages, liabilities or expenses of any kind
(whether in tort, contract or otherwise) arising out of any Loan Party’s or the Administrative

jurisdiction by a final and nonappealable judgment to have resulted from the gross negligence or
willful misconduct of such Agent Party; provided that in no event shall any Agent
Party have any liability to any Loan Party, any Lender or any other Person for indirect,
special, incidental, consequential or punitive damages (as opposed to direct or actual damages).

followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by
the recipient, varied from any confirmation thereof. Each Loan Party agrees, jointly and severally,
to indemnify each Agent and each Lender and the Related Parties of each of them from all losses,
costs, expenses and liabilities resulting from the reliance by such Person on each notice

or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall
survive the execution and delivery hereof and thereof. Such representations and warranties have

either Agent or any Lender or on their behalf and notwithstanding that either Agent or any Lender
may have had notice or knowledge of any

Credit Agreement 69

 

Default at the time of any Loan, and shall continue in full
force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or
unsatisfied or any Commitment shall remain outstanding. The obligations of the Borrower under

Lenders under Section 11.2(c) shall survive the repayment of the Loans and the termination of the
Commitments and, in the case of any Lender that may assign any interest in its Commitment or Loan
hereunder, shall survive the making of such assignment with respect to the assigning Lender,
notwithstanding that such assigning Lender may cease to be a “Lender” hereunder; provided that any
Lender’s obligations under Section 11.2(c) shall only apply to the extent that the event
with respect to which any indemnification is payable thereunder occurred at the time that such
Lender maintained a Loan or Commitment hereunder.

     SECTION 11.8 Successors and Assigns. (a) Successors and Assigns Generally. The
provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby, except that no Loan Party may assign
or otherwise transfer any of its rights or obligations hereunder without the prior written
consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer
all or any portion of its rights or obligations hereunder except (i) to an Eligible Assignee in
accordance with the provisions of clause (b), (ii) by way of participation in accordance
with the provisions of clause (d), or (iii) by way of pledge or assignment of a security
interest subject to the restrictions of clause (and any other attempted assignment or transfer by
any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their respective successors and
assigns permitted hereby, Participants to the extent provided in clause (d) and, to the
extent expressly contemplated hereby, the Related Parties of each of the Agents and the Lenders)
any legal or equitable right, remedy or claim under or by reason of this Agreement.

     (b) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible
Assignees all or a portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it); provided that:

     (i) except in the case of an assignment of the entire remaining amount of the assigning
Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to
a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the
aggregate amount of the Commitment (which for this purpose includes Loans outstanding
thereunder) or, if the Commitment is not then in effect, the principal outstanding balance
of the Loans of the assigning Lender subject to each such assignment, determined as of the
date the Assignment and Assumption with respect to such assignment is delivered to the
Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as
of the Trade Date, shall not be less than, (A) with respect to Revolving Loans, US$5,000,000
(or the Peso Equivalent thereof) and (B) with respect to Tranche B Loans, US$1,000,000, in
each case unless each of the Administrative Agent and, so long as no Event of Default has
occurred and is continuing, the Borrower otherwise consents (each such consent not to be
unreasonably withheld or delayed); provided that concurrent assignments to members of an
Assignee Group and concurrent assignments from members of an Assignee Group to a single
Eligible Assignee (or to an Eligible Assignee and members of its Assignee Group) will be
treated

Credit Agreement 70

 

     as a single assignment for purposes of determining whether such minimum amount has
been met;

     (ii) each partial assignment shall be made as an assignment of a proportionate part of
all the assigning Lender’s rights and obligations under this Agreement with respect to the
Loans or the Commitment assigned;

     (iii) any assignment of a Commitment or a Revolving Loan must be approved by the
Administrative Agent (which approval shall not be unreasonably withheld or delayed) unless
the Person that is the proposed assignee is itself a Lender or an Affiliate of a Lender
(whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and

     (iv) the parties to each assignment shall execute and deliver to the Administrative
Agent an Assignment and Assumption, together with a processing and recordation fee in the amount of US$3,500 and the Eligible Assignee, if it shall not be
a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to clause
(c), from and after the effective date specified in each Assignment and Assumption, the
Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Assumption, be released from its obligations under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations
under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be
entitled to the benefits of Sections 3.1, 3.3, 3.4 and 11.2 with
respect to facts and circumstances occurring prior to the effective date of such assignment. Upon
request, the Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any
assignment or transfer by a Lender of rights or obligations under this Agreement that does not
comply with this clause shall be treated for purposes of this Agreement as a sale by such Lender of
a participation in such rights and obligations in accordance with clause (d).

     (c) Register. The Administrative Agent, acting solely for this purpose as an agent of
the Borrower, shall maintain at the Administrative Agent’s Office a copy of each Assignment and
Assumption delivered to it and a register for the recordation of the names and addresses of the
Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant
to the terms hereof from time to time (the “Register”). The entries in the Register shall be
conclusive, and the Borrower, the Agents and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of
this Agreement and the other Loan Documents, notwithstanding notice to the contrary. The Register
shall be available for inspection by the Borrower at any reasonable time and from time to time upon
reasonable prior notice. In addition, at any time that a request for a consent for a material or
substantive change to the Loan Documents is pending, any Lender may request and receive from the
Administrative Agent a copy of the Register.

Credit Agreement 71

 

     (d) Participations. Any Lender may at any time, without the consent of, or notice to,
the Borrower or the Administrative Agent, sell participations to any Person (other than a natural
person or any Loan Party or any Loan Party’s Affiliates or Subsidiaries) (each, a “Participant”) in
all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or
a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s
obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations and (iii) the Loan
Parties, the Agents and the Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to approve any
amendment, modification or waiver of any provision of this Agreement; provided that such agreement
or instrument may provide that such Lender will not, without the consent of the Participant, agree
to any amendment, waiver or other modification described in the first proviso to Section
11.3 that affects such Participant. Subject to clause (e), the Borrower agrees that
each Participant shall be entitled to the benefits of Sections 3.1, 3.3 and
3.4 to the same extent as if it
were a Lender and had acquired its interest by assignment pursuant to clause (b). To the
extent permitted by Applicable Law, each Participant also shall be entitled to the benefits of
Section 2.14(a) as though it were a Lender if such Participant agrees to be subject to
Section 2.14(b) as though it were a Lender.

     (e) Limitation upon Participant Rights. A Participant shall not be entitled to receive
any greater payment under Section 3.1 or 3.3 than the applicable Lender would have
been entitled to receive with respect to the participation sold to such Participant, unless the
sale of the participation to such Participant is made with the Borrower’s prior written consent.

     (f) Certain Pledges. Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement (including under its Note(s), if any) to
secure obligations of such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any
of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

     (g) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,”
and words of like import in any Assignment and Assumption shall be deemed to include electronic
signatures or the keeping of records in electronic form, each of which shall be of the same legal
effect, validity or enforceability as a manually executed signature or the use of a paper-based
recordkeeping system, as the case may be, to the extent and as provided for in any Applicable Law,
including the Federal Electronic Signatures in Global and National Commerce Act, the New York State
Electronic Signatures and Records Act, or any other similar state laws based on the Uniform
Electronic Transactions Act.

     SECTION 11.9 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan
Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the
maximum rate of non-usurious interest permitted by Applicable Law (the “Maximum Rate”). If the
Administrative Agent or any Lender shall receive interest in

Credit Agreement 72

 

an amount that exceeds the Maximum
Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such
unpaid principal, refunded to the Borrower. In determining whether the interest contracted for,
charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person
may, to the extent permitted by Applicable Law, (a) characterize any payment that is not principal
as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the
effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the
total amount of interest throughout the contemplated term of the Obligations hereunder.

     SECTION 11.10 Submission to Jurisdiction; Venue; Service; Waiver of Jury Trial.

     (a) EACH OF THE PARTIES HERETO (AND ITS SUCCESSORS AND ASSIGNS) (i) AGREES THAT ANY CLAIM,
SUIT, ACTION OR PROCEEDING BROUGHT BY ANY PARTY OR SUCCESSOR THERETO ARISING OUT OF OR WITH RESPECT
TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT SHALL BE SUBJECT TO THE JURISDICTION OF THE COURTS OF
THE STATE OF NEW YORK OR THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK (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 IN RESPECT OF ACTIONS BROUGHT AGAINST IT AS A DEFENDANT 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 LOAN DOCUMENT
BROUGHT IN ANY SUCH COURT, (B) IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH SUIT, ACTION OR
PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM, (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 AND (D) IRREVOCABLY WAIVES ANY RIGHT
TO WHICH IT MAY BE ENTITLED ON ACCOUNT OF PLACE OF RESIDENCE OR DOMICILE. 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.

     (b) EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY

Credit Agreement 73

 

HERETO (i) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVER AND (ii) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE
MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     (c) FOR THE PURPOSE OF PROCEEDINGS IN THE COURTS OF THE STATE OF NEW YORK AND THE UNITED
STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK (IN EACH CASE LOCATED IN THE BOROUGH OF
MANHATTAN IN NEW YORK CITY), EACH LOAN PARTY HEREBY IRREVOCABLY DESIGNATES AS OF THE EFFECTIVE DATE
CT CORPORATION SYSTEM (“PROCESS AGENT’) 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, EACH LOAN PARTY 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 EACH SUCH LOAN PARTY AND THAT FAILURE OF ANY SUCH AGENT TO GIVE ANY NOTICE
OF SUCH SERVICE TO SUCH LOAN PARTY SHALL NOT AFFECT THE VALIDITY OF SUCH SERVICE OR ANY JUDGMENT
RENDERED IN ANY ACTION OR PROCEEDING BASED THEREON. 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 11.5 OR SCHEDULE 11.5. WITH RESPECT TO
EACH LOAN PARTY, SERVICE OF ANY AND ALL SUCH PROCESS OR OTHER DOCUMENTS TO THE PROCESS AGENT OR
SUCH OTHER AGENT FOR SERVICE OF PROCESS DESIGNATED BY SUCH LOAN PARTY IN ACCORDANCE WITH THIS
AGREEMENT SHALL CONSTITUTE VALID AND EFFECTIVE SERVICE ONLY IF MADE IN PERSON TO THE PROCESS AGENT
OR SUCH OTHER AGENT FOR SERVICE OF PROCESS.

     SECTION 11.11 Judgment Currency. All payments made under this Agreement and the Notes shall be made in
Dollars or Pesos (to the extent required by the terms hereof, the applicable “Agreement Currency”),
as applicable, and, if for any reason any payment made hereunder or under any Note is made in a
currency (the “Other Currency”) other than the applicable Agreement Currency, then to the extent
that the payment actually received by the relevant Beneficiary, when converted into the applicable
Agreement Currency 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 such
Beneficiary to purchase the applicable Agreement Currency) falls short of the amount due under the
terms of this Agreement or any

Credit Agreement 74

 

Note, the Loan Parties shall, as a separate and independent
obligation of the Loan Parties, indemnify such Beneficiary and hold such Beneficiary harmless
against the amount of such shortfall. As used in this Section 11.11, the term “Rate of
Exchange” means the rate at which the Beneficiary is able on the relevant date to purchase the
applicable Agreement Currency with the Other Currency and shall include any premiums and costs of
exchange payable in connection with the purchase of or conversion into, the applicable Agreement
Currency.

     SECTION 11.12 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 11.13 Waiver of Immunities. To the extent that any Loan Party 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, such Loan Party hereby irrevocably waives such immunity in
respect of its obligations under this Agreement and the other Loan Documents. The foregoing waiver
is intended to be effective to the fullest extent now or hereafter permitted by Applicable Law.

     SECTION 11.14 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 11.15 Treatment of Certain Information; Confidentiality. Each of the Agents and the Lenders
agrees to maintain the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective
partners, directors, officers, employees, agents, advisors and representatives (it being understood
that the Persons to whom such disclosure is made will be informed of the confidential nature of
such Information and be required to keep such Information confidential), (b) to the extent
requested by any regulatory authority purporting to have jurisdiction over it (including any
self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the
extent required by Applicable Laws or by any subpoena or similar legal process, (d) to any other
party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan
Document or any action or proceeding relating to this Agreement or any other Loan Document or the
enforcement of rights hereunder or thereunder, (f) subject to an agreement with each Person
receiving the Information containing provisions substantially the same as those of this Section, to
(i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its
advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g)
with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly
available other than as a result of a breach of this Section or (ii) becomes available to such
Agent, any Lender, or any of their respective Affiliates on a nonconfidential basis from a source
other than the Borrower.

Credit Agreement 75

 

     For purposes of this Section, “Information” means all information received from any Loan Party
or any Subsidiary relating to any Loan Party or any Subsidiary or any of their respective
businesses, other than any such information that is available to either Agent or any Lender on a
nonconfidential basis prior to disclosure by such Loan Party or Subsidiary; provided that, in the
case of information received from a Loan Party or any Subsidiary after the date hereof, such
information is clearly identified at the time of delivery as confidential. Any Person required to
maintain the confidentiality of Information as provided in this Section shall be considered to have
complied with its obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to its own
confidential information.

     Each of the Agents and the Lenders acknowledges that (a) the Information may include material
non-public information concerning a Loan Party or a Subsidiary, as the case may be, (b) it has
developed compliance procedures regarding the use of material non-public information and (c) it
will handle such material non-public information in accordance with Applicable Law, including
Federal and state securities laws.

     SECTION 11.16 No Waiver; Remedies. No failure on the part of either Agent or any of the Lenders 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 11.17 Entire Agreement. As of the Effective Date, this Agreement and the other Loan Documents
(including the Fee Letters with respect to the matters covered thereby) constitute the entire
agreement among the parties with respect to the subject matter hereof and thereof and supersede all
prior or contemporaneous agreements and understandings of such Persons, verbal or written, relating
to the subject matter hereof and thereof.

     SECTION 11.18 USA PATRIOT Act. Each Lender that is subject to the Act (as hereinafter defined) and the
Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that
pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law
October 26, 2001)) (the “Act’), it is required to obtain, verify and record information that
identifies the Borrower, which information includes the name and address of the Borrower and other
information that will allow such Lender or the Administrative Agent, as applicable, to identify the
Borrower in accordance with the Act.
