CLAUSES

ONE. PURPOSE. Caterpillar will purchase the Assets directly from the vendor, manufacturer or builder specified by Lessee, for the purpose of granting Lessee the use and enjoyment thereof, and Lessee shall accept and take the assets in such capacity.

This agreement will apply to any mechanism, spare, part or component used in a supplementary fashion or subsequently added to the Assets.

TWO. SELECTION AND DELIVERY OF ASSETS. Since Lessee has directly selected the vendor of the Assets and has authorized the terms, conditions and specifications of such Assets, identifying and describing same, Caterpillar, in accordance with Article 413 of the General Law of Negotiable Instruments and Credit Transactions ("LGTOC"), is not liable for any errors or omissions in the selection or description thereof, or with respect to the condition of same.

The physical delivery of the Assets will be performed directly by the vendor to Lessee, and Lessee agrees to receive same. The parties must deliver a receipt of the Assets and/or of the amounts specified in this clause, as appropriate.

All expenses arising in connection with the transportation, delivery and installation of the Assets shall be borne by Lessee. If Lessee refuses to receive the Assets for any reason, Lessee will reimburse Caterpillar for all amounts paid thereby in connection with such Assets, plus all interest accrued from the date on which such amounts were paid by Caterpillar until the date of reimbursement, with such interest calculated using the interest rate stipulated herein to set rent payments, without prejudice to Caterpillar's right to terminate this agreement early, adhering to the stipulations of Clause Twenty-Eight hereof.

Caterpillar will have no liability whatsoever for any loss, damage or delay in delivery of the Assets.

Lessee will assume the risk for the cases mentioned in this paragraph.

THREE. VALUE OF ASSETS IN DOLLARS. The parties agree that, in the event this agreement is in pesos and the Assets are billed by the vendor in U.S. dollars, they will be subject to the following: (i) If, because of appreciation of the peso, the value of the Assets proves to be lower than the stipulated amount, the difference will be applied, in Lessee's favor, to the first Installment of the Total Rent and listed on the account statement to be delivered to Lessee; or (ii) If, because of depreciation of the peso, the value of the Assets proves to be higher than the stipulated amount, the difference will be payable to Caterpillar, added to the first Installment of the Total Rent and listed on the account statement to be delivered to Lessee;

For purposes of this clause, the exchange rate used will be the FIX exchange rate determined by Banco de México and published on its website (▇▇▇.▇▇▇▇▇▇▇.▇▇▇.▇▇) on the date on which Caterpillar makes payment to the vendor for the Assets, which, in accordance with applicable regulations, will be the same as that published in the Federal Official Gazette ("DOF") on the next business day.

FOUR. CO-LESSEES.

The parties furthermore agree that the term hereof may be extended through agreement of the parties.

SIX. RENT. As consideration for the use and enjoyment of the Assets, Lessee agrees to pay Caterpillar the amount set forth in Appendix A hereof, under the heading "Total Rent," which is established as the lease price plus the respective VAT, composed of a fixed portion – the "Invoice Price excluding VAT" of the Assets, specified in Appendix A, and a variable portion pursuant to Clause Seven hereof; Appendix A may also specify a fixed rate, in which case the aforementioned rent variation will not apply.

The mere application by Caterpillar of payments made by Lessee may not signify that Lessee breaches its obligations hereunder, or generate additional costs for Lessee.

If the currency stipulated is foreign, the obligation will be paid in the equivalent in Mexican pesos at the FIX exchange rate determined by Banco de México and published on its website (▇▇▇.▇▇▇▇▇▇▇.▇▇▇.▇▇) on the date of payment, which, in accordance with applicable regulations, will be the same as that published in the Federal Official Gazette ("DOF") on the next business day.

In the event of such a change, the parties agree that the exchange rate to recalculate the Total Rent and the Installments will be the FIX exchange rate determined by Banco de México and published on its website (▇▇▇.▇▇▇▇▇▇▇.▇▇▇.▇▇) on the date on which the amendment agreement is executed; in the event of any discrepancy with the FIX exchange rate published in the DOF the next business day, the latter will prevail with all the associated de facto and de jure consequences. Notwithstanding the foregoing, if there is any change in the FIX exchange rate between the date of the amendment agreement and the date on which Caterpillar records and posts such amendment, the parties agree as follows: (i) if the change in the FIX exchange rate is an increase, Lessee must pay Caterpillar the difference on the payment date for the next installment; (ii) if the change in the FIX exchange rate is a decrease, Caterpillar shall refund the difference to Lessee on the payment date for the next installment.

Caterpillar shall authorize, as appropriate, Lessee to exercise the actions or defenses where necessary under Article 414 of the LGTOC.

TWENTY-ONE. INSURANCE. The Assets must be insured or guaranteed in accordance with articles 417 and 418 of the LGTOC.

Premiums and costs incurred in obtaining and renewing insurance for the Assets must be paid by Lessee within 3 business days after the date on which Caterpillar notifies Lessee of same. The parties agree that failure to make timely payment of the foregoing will result in default interest at the rate stipulated in this agreement.

An extension of the term to continue the use and temporary enjoyment of the Assets for the period specified in Appendix A hereof under the heading "Extension Term," during which the rent payments will be those set out in Appendix A under the heading "Extension Rent," and these will be lower than the installments paid by Lessee to Caterpillar during the original term.

c)	Receiving a share of the proceeds from the sale of the Assets to a third party, in which case its share will be that set out in Appendix A of this agreement, under the heading "Share of Proceeds from Sale."

Lessee will inform Caterpillar of the option it chooses in writing at least 90 days prior to the expiration of this agreement. If Lessee does not specify the chosen option, both parties will understand that Lessee accepts the aforementioned option a).

All taxes, fees, charges or costs of any kind incurred by reason of exercising option a) above will be exclusively borne by Lessee.

Caterpillar's obligation in the terms of this clause will be subject to Lessee being current on each and every one of its obligations under this agreement and its appendices.

Lessee will be liable for damages for breach in choosing the agreement-end option.

Caterpillar may not object to the aforementioned option being carried out, except where Lessee is in breach of any of its payment obligations contained in this agreement and its Appendix A.

TWENTY-SEVEN. EARLY TERMINATION OF LEASE. The parties may terminate this agreement early by mutual agreement. In such a case, they must execute the appropriate termination agreement in which they will stipulate the manner in which all outstanding obligations are to be fulfilled.

TWENTY-EIGHT. CAUSES OF DEFAULT AND EARLY TERMINATION. The parties agree that Caterpillar may terminate the lease hereunder early without any court order in the following cases:

a)	For delay and/or failure to make timely payment of any rent Installments or any other amount to be paid by Lessee under this agreement and its appendices.

b)	For Lessee's nonfulfillment of tax obligations or failure to make the proper contribution payments to the Mexican Social Security Institute, unless such payments are legally contested and an adequate reserve fund is established.

c)	For failure of Lessee to inform Caterpillar immediately of any situation that may physically or legally affect the Assets.

d)	For attachment of the Assets, regardless of the cause thereof.

e)	For breach of any obligation hereunder.

f)	For insolvency or bankruptcy of Lessee.

g)	In the event of individual or collective workers' claims against Lessee that may affect the possession, proper operation or preservation of the Assets.

h)	In the event Lessee employs the Assets for any use or purpose other than appropriate normal use.

i)	In the event Lessee foregoes performing, on its own account, at its own expense and in a timely fashion, any repairs or maintenance services necessary for the Assets to remain in perfect working condition, with the normal wear and tear from use and the passage of time.

j)	In the event Lessee foregoes insuring and maintaining the insurance on the Assets in the terms specified in the Insurance clause herein.

k)	In the event that Lessee moves the Assets to a place other than that specified in Appendix A, under the heading "Location of the Leased Assets" or subleases same without prior written consent from Caterpillar.

l)	In the event Lessee refuses to allow Caterpillar to inspect the Assets and to provide information on their location.

The legal consequences of early termination of this agreement for any of the above reasons will be: (i) dissolution of the contractual relationship; (ii) the obligation of Lessee to return the Assets to Caterpillar immediately upon notice of early termination; (iii) the obligation of Lessee to immediately pay Caterpillar the amount set forth in Appendix A of this contract under the heading "Total Rent" plus default interest and any other ancillary charges generated until payment is made, and pay the contractual penalty specified in Appendix A hereof under the heading "Contractual Penalty."

In the event Lessee does not return the Assets immediately upon the notice of early termination, it shall pay Caterpillar the contractual penalty specified in Appendix A under the heading "Contractual Penalty," without prejudice to the penalty applicable to breach of trust provided for in Article 229 of the Criminal Code of Mexico City, Federal District and its counterparts in the criminal codes of the states of the Mexican Republic. Upon return of the Assets, the parties agree that Caterpillar may, if it so desires, sell the Assets to third parties.

TWENTY-NINE. CANCELLATION OF AGREEMENT. Caterpillar and Lessee agree that Lessee may request cancellation of this Agreement within 10 business days after execution hereof, without any liability to same, provided the Assets have not yet been purchased.

Independently from the aforementioned request, the parties agree that in any other case in which Lessee requests the cancellation of this agreement, the parties shall be subject to the following: (i) Lessee shall submit a letter to the SPECIALIZED UNIT requesting cancellation of the agreement; (ii) Caterpillar must provide Lessee with a cancellation code; (iii) In the event Lessee requests termination of the agreement and there is no debt or outstanding amount owed thereby, Caterpillar will terminate the agreement no later than the business day following that on which such a request is received. In the event there are outstanding debts, Caterpillar will inform Lessee on the business day following receipt of the aforementioned request of the amount of the outstanding balance arising from the obligations hereunder, making such notice available to Lessee at the domicile of the SPECIALIZED UNIT within five working days of receipt of the termination request; and (iv) Caterpillar must, as appropriate, make available to the Lessee, at the aforementioned address, the balance as of the date of termination of the transaction.

In the event Lessee cancels this agreement, it must pay Caterpillar all debts it owes, on the date of cancellation hereof.

In the event Lessee does not receive any of the account statements for any reason, it may request the missing statement from Caterpillar's SPECIALIZED UNIT indicated in Clause Forty.

This authorization will remain in place until the end of the legal relationship between CATERPILLAR CRÉDITO, S.A.

	FEDERAL CIVIL CODE:

	Article 1913. When a party uses mechanisms, instruments, devices or substances that are hazardous in and of themselves, due to the speed involved, due to their explosive or flammable nature, due to the electrical current they conduct or due to other similar causes, that party will be held accountable for any damage it causes, even where it has not acted illegally, unless such party is able to demonstrate that the damage was caused by the inexcusable fault or negligence of the victim.

	Article 1987. In addition to joint liability, there will be active joint and several liability when two or more creditors have the right to demand, each on its own, full performance of the obligation, and passive joint and several liability when two or more debtors report the obligation to provide, each one on its own, the full performance due.

	VALUE ADDED TAX LAW:

	Article 18-A. To calculate taxes, the value will be considered to be the actual value of the accrued interest arising from credit facilities granted by the financial system institutions referenced in Article 8 of the Income Tax Law, on credit facilities issued by means of line of credit or checking account agreements where the borrower or checking account holder may draw down on credit by using cards issued by the lender, and on finance lease transactions.

	For the transactions referenced in this article, the fees charged to the debtor, borrower, checking account holder or lessee for drawdowns of cash or any other item, and contractual penalties, except default interest, will not be considered to be part of the accrued interest.

	The actual value of the accrued interest will be determined as follows:

	I. When the transaction in question is denominated in the domestic or a foreign currency, the actual value of the interest will be calculated by applying the base used to calculate accrued interest, the actual interest rate, in accordance with the following:

	a) The actual interest rate will be calculated by subtracting the inflation for the period involved from the interest rate for that same period. Inflation will be calculated by dividing the investment unit value set by Banco de México for the last day in the period by the investment unit value for the day immediately prior to the first day in the period and subtracting the unit quotient.

	b) When the credit transaction is in foreign currency, the exchange rate gains accrued in the period involved, expressed as a proportion of the average principal balance for that same period, will be added to the pertinent interest rate for that period. To express the exchange rate gains accrued in the period involved as a proportion of the average principal balance for that same period, the exchange rate gains in Mexican pesos will be divided by that average balance converted into Mexican pesos at the exchange rate published by Banco de México in the Federal Official Gazette for the last day in the period in which interest is accrued. If Banco de México does not publish the exchange rate, the last exchange rate published by that institution prior to that date will be applied. The average principal balance will be the sum of the daily principal balances in the period divided by the number of days in that same period in which interest is accrued.

		When the result of adding up the interest rate for the period and the exchange rate gains accrued in the same period expressed in the terms of the preceding paragraph is equal to or less than the inflation in the period in which interest is accrued, no tax will be due for that period.

		If the interest rate for the period is expressed as a percentage, it should be divided by one hundred prior to doing the additions and subtractions as mentioned in the preceding paragraphs.

		II. When the transactions involved are denominated in investment units, the actual value of the interest will be the interest accrued in the period without considering the adjustment pertaining to the principal due to being denominated in investment units.


	When the payment for interest accrued monthly is not received for a period of three consecutive months, the taxpayer may, beginning with the fourth month, defer the tax on interest that is accrued beginning with that month until the month when the payment is actually received. Beginning with the month when the full payment is received for the accrued interest that was not collected as referenced in this paragraph, the pertinent tax on the interest that is accrued subsequently will take effect on the month when the interest is accrued. The contents of this paragraph will only be applicable to finance leases for transactions engaged in with the general public.

	For credit transactions or finance leases in foreign currency that are entered into with the general public, to calculate interest, instead of the actual value of the accrued interest referenced in this article, the value of the accrued interest may be considered. When this option is exercised for a credit facility, it may not be changed during the lifetime of that credit facility.

	GENERAL SPECIAL-PURPOSE FINANCIAL INTERMEDIARIES AND ACTIVITIES LAW:

	Article 87-F. The agreement recording the credit facility, finance lease or factoring executed by multiple-purpose financial institutions, so long as the instrument is accompanied by a certification of the pertinent account statement as referenced in the preceding article, will be a commercial executory instrument without the need for authentication of signature or any other requirement whatsoever.

	The account statement specified in the first paragraph of this article must contain the identification information on the contract or agreement recording the credit facility, factoring or finance lease that has been executed, the initial capital available or, as the case may be, the determined rent payment, the principal, or, as the case may be, outstanding, unpaid rent; principal or, as the case may be, rent coming due; the credit interest rate or, as the case may be, the variability of the rent applicable to the rent that may be determined for each payment period, default interest incurred, the interest rate applicable to default interest, and the amount of ancillary fees incurred.

	Article 87-J. Finance lease, factoring, or credit facility agreements that are entered into by multiple-purpose financial institutions must expressly indicate that, for the agreements to be created and operate as such, they do not require authorization from the Secretary of Treasury and Public Credit. The same thing must be stated in any type of information that multiple-purpose financial institutions use to promote their operations and services.

	In addition to the foregoing, multiple-purpose unregulated financial institutions must state, in the documentation and information referenced in the preceding paragraph, that they are not subject to supervision and oversight by the National Banking and Securities Commission to engage in the transactions indicated in that same paragraph.

	GENERAL LAW ON NEGOTIABLE INSTRUMENTS AND CREDIT TRANSACTIONS:

	Article 4. For credit transactions that are governed by this law, it is presumed that the co-debtors are jointly and severally bound.

	Article 408. In virtue of the finance lease agreement, the lessor undertakes to acquire certain assets and grant their temporary use or enjoyment for a mandatory term to the lessee, who may be an individual or company. The latter undertakes to pay, as consideration, in installment payments, as agreed, an amount of money that is determined or that is to be determined, to pay for the purchase of the goods, financial charges, and other ancillary fees as stipulated, and choose, upon the expiration of the agreement, one of the ending options referenced in Article 410 of this Law.

	Finance lease agreements must be executed in writing and may be registered in the Public Registry of Commerce at the request of the parties to the agreement without prejudice to registering it in other registries as determined by law.

	In the case specified in the preceding paragraph, the parties must stipulate the period in which the advance payments are to be made, after which the lessee must pay them in the finance lease with the characteristics and conditions agreed to in the pertinent agreement.

	Article 414. Unless stipulated otherwise, the lessee is responsible for the following:

	I. Any hidden defects or faults in the assets that impede their partial or total use. In such a case, the lessor will transfer to the lessee the rights pertaining thereto as buyer so the lessee may exercise them against the seller or will authorize the lessee to represent it to exercise said rights.

	II. Full or partial loss of the assets, even where the loss is due to force majeure or acts of God; and

	III. In general, any risks, losses, theft, destruction or damage affecting the assets under the finance lease.

	In the event of the specified contingencies, the lessee is not released from making the payment for consideration and must make payment as agreed to in the agreement.

	Article 417. Any insurance or guarantee that is set forth in finance lease agreements must cover, under the terms as stipulated, at least the risks involved in construction, transportation, receipt, or installation, depending on the nature of the assets, damages or losses to the assets themselves, in connection with their possession and use, as well as civil and professional liability of any nature that may be caused in light of the use or enjoyment of the assets themselves, when dealing with assets that may cause personal or property damage to third parties.

	The agreements or documents recording the guarantee must indicate the lessor as primary beneficiary so that, first of all, with the payment for compensation the lessor is paid the outstanding balances for the obligation under agreement, or the liability to which the lessor is bound as the owner of the assets. If the compensation amount paid does not cover the balances or liability, the lessee must pay the shortfall.

	Article 418. Insurance premiums and expenses will be borne by the lessee, even when the lessor takes out the insurance referenced in the preceding article, should the case be such that the insurance is stipulated to be taken out by the lessee and the lessee does not do so within three days after the agreement is executed. This is without prejudice to this omission being considered to be grounds for termination of the agreement.

	LAW FOR FINANCIAL SERVICES TRANSPARENCY AND REGULATION:

	Through the means stipulated with their clients, entities must announce any increase in fee amounts as well as any new fees to be charged at least thirty calendar days in advance of the date provided for the changes to take effect. Without prejudice to the foregoing, under the terms set forth in the agreements, clients will have the right to terminate the provision of services provided by the entities if they do not agree with the new amounts without the entity being able to charge any additional sum whatsoever therefor, with the exception of the amounts owed that would have already been generated as of the date when the client requests that the service be terminated.

	Breach of the contents of the preceding paragraph will result in the invalidation of the fee, independently of any penalties that may be appropriate.

	MONETARY LAW OF THE UNITED MEXICAN STATES.

	Article 8. Foreign currency is not legal tender in the Republic except in cases when the Law expressly deems otherwise. Payment obligations in foreign currency that are entered into inside or outside the Republic will be complied with in Mexico by providing an equivalent amount in Mexican pesos at the current exchange rate in the place and on the date that the payment must be made.

	The exchange rate will be determined based on the provisions that Banco de México issues under the terms of its Constitutional Law.

	Payments in foreign currency arising from situations or funds transfers from abroad that are carried out through Banco de México or financial institutions must be fulfilled by delivering the currency that underlies the transfer or situation. This is without prejudice to enforcement of the obligations that the current exchange rate program entails.

	The obligations referenced in the first paragraph of this article that arise from irregular bank deposits created in foreign currency will be settled based on the contents of that paragraph unless the debtor is expressly bound to make the payment in precisely that foreign currency, in which case that currency must be delivered. The latter payment method may only be stipulated in cases where the competent banking authorities authorize it by means of general rules that must be published in the Federal Official Gazette. This is without prejudice to enforcement of the obligations that are entailed in the current exchange rate program.
