Agreement to cause such sections to be applicable to the option and put relating
to the Port Shares. In no event shall the Series 2002-A Certificateholders or
the Trustee have any obligation to execute and enter into documentation or
amendments to effectuate the Put Option Exchange Transaction unless such
documentation or amendments are approved and executed by the Series 2001-A
Certificateholders. The obligations of the Series 2002-A Certificateholders
under this SECTION 10.6 hall automatically terminate if the Put Option Exchange
Transaction is not completed on or before December 31, 2002. For purposes of

Certificateholders (Super Majority), releases its option and put rights with
respect to the Grupo TFM Shares as set forth in the Option Agreement and the Put
Agreement, in exchange for the grant on substantially identical terms of an
option and put with respect to the Port Shares.

(iii) right to amend or alter the purchase price for the Purchased Receivables.

          (b)     The parties agree and confirm their understanding that neither
the Sellers nor any of their subsidiaries or Affiliates in any way guarantees
payment of the Purchased Receivables and neither the Sellers nor any of their
respective subsidiaries or Affiliates shall be liable for non-payment of any
Purchased Receivables by any Customer Obligor. The foregoing will not limit
Sellers' repurchase obligations under any Supplement, including Section 3.1 of
the Series 2001-A Supplement or the Series 2002-A Supplement, or limit TMM's
liability as Servicer and Guarantor with respect to its representations and
warranties, indemnifications or covenants under the Transaction Documents or to
pay any amounts for which it has recourse liability to pay under any Transaction
Document.

     Section 2.3  ACCEPTANCE BY TRUSTEE.

          (a)     The Trustee hereby acknowledges its acceptance, on behalf of
the Trust, of all right, title and interest previously held by each Seller in
and to (i) the Purchased Receivables, (ii) all funds collected or to be
collected in respect of the Purchased Receivables, (iii) all proceeds of amounts
payable with respect to the Purchased Receivables and (iv) the other Trust
Assets, and declares that it shall maintain such right, title and interest, and
other Trust Assets in Trust as herein set forth, for the benefit of all Investor
Certificateholders subject to the rights of the Series 2001-A Certificateholders
to the prior rights to certain repurchase payments payable on a recourse basis
by TMM as described at Section 3.1(a) of each of the Supplements and to receive
all TMM Prepayment Proceeds, as more fully set forth in the Transaction
Documents.

          (b)     The Trustee shall have no power to create, assume or incur
indebtedness or other liabilities in the name of the Trust other than as
contemplated in this Master Trust Agreement.

     Section 2.4  ISSUANCE OF CERTIFICATES. The Trust may from time to time
issue Investor Certificates relating to any Series in accordance with ARTICLE V
hereof that shall represent undivided interests in the Trust Assets.

     Section 2.5  TAX INDEMNITY.

                                       30
<Page>

          (a)     The Sellers and the Sellers' Representative hereby agree to
jointly and severally indemnify and hold harmless the Trustee and its respective
trust delegates, officers, directors, advisors, attorneys and personnel
(collectively, the "INDEMNIFIED PERSONS") for all payments, liabilities and
damages that may result from any Sellers' or the Sellers' Representative's
non-performance of its tax obligations (the "TAX OBLIGATIONS") provided by
Mexican Applicable Law, or that arise from any transaction pursuant to or
derived from any of the Transaction Documents, as well as for Taxes, fees,
penalties or damages that may arise in case a claim, proceeding, judgment or
complaint is filed or presented against any of the Indemnified Persons in
connection with the Tax Obligations or the transactions contemplated herein or
for failure by any of the Sellers or the Sellers' Representative to comply with
its Tax Obligations. As a result, the Sellers and the Sellers' Representative
jointly and severally agree to reimburse the Indemnified Persons for any expense
of any nature incurred (including reasonable and documented attorney's fees and
expenses), and to repair any damages that such Indemnified Person may have
suffered as a result of its participation in any of the transactions or actions
contemplated herein.

          (b)     The obligations of the Sellers and the Sellers' Representative
specified in paragraph (a) above shall not be applicable in respect of the
Trustee or the Indemnified Persons in case of gross negligence, willful
misconduct or bad faith of the Trustee or any Indemnified Person.

          (c)     The obligation of the Sellers and Sellers' Representative
specified in this SECTION 2.5 shall be in addition to and not in limitation of
any other right or remedy which may be afforded to the Indemnified Persons under
this Master Trust Agreement or Applicable Law and shall survive the termination
of this Master Trust Agreement.

     Section 2.6  TAX TREATMENT.

          (a)     It is the intent of the parties hereto that for United States
federal, state and local income tax purposes the Investor Certificates to be
issued hereunder will constitute indebtedness of the Sellers secured by the
Purchased Receivables and the Trust will constitute a security arrangement and
not a separate entity, and the parties hereto and each Certificateholder, by
acceptance of its Investor Certificate, agree to so treat the Investor
Certificates and the Trust for United States federal, state and local income tax
purposes.

          (b)     In the event that either the Investor Certificates or the
Trust is not so treated for United States federal, state or local income tax
purposes by any United States federal, state or local taxing authority, then it
is the intent of the parties hereto that the Trust and related arrangements be
treated for United States federal, state and local income tax purposes in a
manner that minimizes any liability of the Trust, Certificate Owners and the
Certificateholders for such federal, state and local taxes (without unduly
prejudicing the tax position of the Sellers) and the parties hereto and each
Certificateholder and Certificate Owner, by acceptance of its Investor
Certificate, agree to use its reasonable efforts (consistent with legal and
regulatory restrictions) to ensure that the Trust is not treated as an
association taxable as a corporation, for all United States federal, state and
local income tax purposes and to take no steps inconsistent with such treatment,
to the extent permitted by Applicable Law. Each Certificateholder and
Certificate Owner agrees that it will obtain from any Certificateholder or
Certificate Owner

                                       31
<Page>

acquiring an interest in a Certificate from or through it (whether by purchase,
assignment, participation or otherwise) a written agreement to comply with this
SECTION 2.6.

     Section 2.7  TRUE SALES.

          (a)     Each of the Sellers and the Trustee intend the transfers of
the Purchased Receivables under the Receivables Sale Agreements to be true sales
by the Sellers to the Trust that are absolute and irrevocable and that provide
the Trust with the full benefits of ownership of the Purchased Receivables, and
except as otherwise specifically provided for in SECTION 2.6 of this Master
Trust Agreement, neither the Sellers nor the Trustee intends the transactions
contemplated by the Receivables Sale Agreements to be characterized as loans
from the Trust to the Sellers.

          (b)     In the event that, notwithstanding the intent of the parties
expressed under the Receivables Sale Agreements, the transfers of the Purchased
Receivables are not true sales, then the Sellers intend that such transfers by
them to be a grant of a security interest in such property within the meaning of
the UCC. The Sellers therefore grant to the Trustee on behalf of the Trust and
the Investor Certificateholders, a first priority security interest in and to
all of the Sellers' right, title and interest in, to and under the Purchased
Receivables, the other Trust Assets, all funds collected or to be collected in
respect of the Purchased Receivables and all proceeds thereof for the purpose of
securing a loan in a principal amount equal to the Aggregate Certificate Balance
from time to time of the Investor Certificates issued hereunder and pursuant to
any applicable Supplement and the interest accrued at the related Certificate
Rate and to secure all of the Sellers' and TMM's obligations hereunder, under
any applicable Supplement and each other Transaction Document.

          (c)     In connection with such conveyance and grant of a security
interest, TMM agrees that, if it or any other Seller should at any time open an
executive office or offices in any state in the United States, (x) it will
promptly record and file, at its own expense, all financing statements
(including any continuation statements with respect to such financing statements
when applicable) in such jurisdiction as may be required to evidence the
security interest of the Trustee with respect to the Purchased Receivables
originated or to be originated by the Sellers, all funds collected or to be
collected in respect of the Purchased Receivables and all proceeds thereof, and
(y) it will deliver promptly a file-stamped copy of such financing statements or
continuation statements or other evidence of such filing to the Trustee. The
foregoing conveyance and grant to the Trust is made to the Trustee, on behalf of
the Trust, and each reference in this Master Trust Agreement to such conveyance
and grant shall be construed accordingly. The Trustee shall be under no
obligation whatsoever to file the financing statements or continuation
statements referred to herein, or to make any other filing under the UCC or
otherwise in connection with the foregoing conveyance and grant.

                                   THE SELLERS

     Section 3.1  REPRESENTATIONS AND WARRANTIES OF THE SELLERS.

                                       32
<Page>

          (a)     SELLERS. TMM represents on behalf of itself and each other
Seller (it being understood that any reference below in this ARTICLE III to
"Seller" when applicable to TMM shall also mean TMM in its role as Guarantor,
Sellers' Representative and to the extent applicable Servicer), and each other
Seller hereby represents and warrants as to itself to the Trust and the Trustee
as of the Document Closing Date, the Initial Closing Date and each subsequent
Closing Date (including the Third Closing Date) and, to the extent expressly set
forth herein, any other date:

                 (i)    ORGANIZATION. Each Seller is a Mexican corporation duly
     organized and validly existing as a SOCIEDAD ANONIMA DE CAPITAL VARIABLE
     under the laws of Mexico. Each Seller has full corporate power, authority
     and legal right to own its properties and conduct its business as such
     properties are presently owned and such business is presently conducted,
     and to execute, deliver and perform its obligations under the Transaction
     Documents in all material respects.

               (ii)     WHOLLY OWNED SUBSIDIARY. Each Seller, other than TMM,
     is a Wholly-Owned Subsidiary of TMM.

               (iii)    DUE QUALIFICATION. Each Seller is duly qualified to do
     business (or is exempt from such requirement) in any jurisdiction where
     such qualification is required in order to conduct its business as such
     business is presently conducted, and has obtained all licenses and
     approvals and made all filings required under the law of such jurisdiction
     the absence of which is reasonably likely to result in a Material Adverse
     Effect.

                (iv)    DUE AUTHORIZATION. The execution and delivery of the
     Transaction Documents by each Seller and the consummation of the
     transactions provided for in the Transaction Documents have been duly
     authorized by each Seller by all necessary corporate and shareholder action
     on its part.

                (v)     NO CONFLICT. The execution and delivery of the
     Transaction Documents by each Seller, the performance of the transactions
     contemplated by the Transaction Documents and the fulfillment of the terms
     thereof will not conflict with or result in the breach of any of the
     material terms and provisions of, or constitute (with or without notice or
     lapse of time or both) a default under, (a) any of the Indentures, or (b)
     except for any conflict, breach or default which is not reasonably likely
     to result in a Material Adverse Effect, any other indenture, contract,
     agreement, mortgage, deed of trust or other instrument to which each Seller
     is a party or by which it or any of its properties is bound.

               (vi)     NO VIOLATION. The execution and delivery of the
     Transaction Documents by each Seller, the performance of the transactions
     contemplated by the Transaction Documents by each Seller and the
     fulfillment of the terms hereof will not conflict with or violate its
     certificate of incorporation, articles of association, by-laws, ACTA
     CONSTITUTIVA, ESTATUTOS SOCIALES, or other organizational or governing
     documents or any law, treaty, rule or regulation, or determination of an
     arbitrator or Governmental Authority in each case applicable to or binding
     upon such Seller or to which such Seller

                                       33
<Page>

     is subject, except for any conflict or violation which is not reasonably
     likely to result in a Material Adverse Effect.

               (vii)    NO PROCEEDINGS. There are no proceedings or
     investigations pending or, to the best knowledge of each Seller, threatened
     against it, before any court, regulatory body, administrative agency or
     other tribunal or governmental instrumentality (a) asserting the invalidity
     of the Transaction Documents, (b) seeking to prevent the issuance of the
     Certificates or the consummation of any of the transactions contemplated by
     the Transaction Documents or (c) seeking any determination or ruling that
     is reasonably likely to result in a Material Adverse Effect.

               (viii)   ALL CONSENTS REQUIRED. All governmental authorizations,
     consents, orders or other actions of any Person or of any governmental body
     or official required in connection with the execution and delivery of the
     Transaction Documents (other than for Transaction Documents to be delivered
     on the Initial Closing Date for which this representation is first given as
     of the Initial Closing Date), the performance of the transactions
     contemplated by the Transaction Documents (other than consents or
     authorizations required to be obtained in connection with (A) the Newco
     Transfer and (B) the exercise of the Call Option or Port Option, as defined
     in the Option Agreement or Port Option Agreement and as set forth in the
     Option Agreement or Port Option Agreement, each as applicable), and the
     fulfillment of the terms thereof by each Seller, have been obtained except
     to the extent that the failure to obtain the same is not reasonably likely
     to result in a Material Adverse Effect.

               (ix)     ACQUISITION OF EQUITY SECURITIES. No proceeds of the
     transfer of Purchased Receivables by each Seller to the Trust will be used
     by such Seller to acquire any equity security of a class which is
     registered under the Securities Act or pursuant to Section 12 of the
     Securities Exchange Act of 1934, as amended.

               (x)      MARGIN STOCK. No Seller is engaged principally, or as
     one of its important activities, in the business of extending credit for
     the purpose of purchasing or carrying Margin Stock. No proceeds of the
     transfer of Purchased Receivables to the Trust will be used for the purpose
     of, or be made available by such Seller in any manner to any other Person
     to enable or assist such Person in, purchasing or carrying Margin Stock.

               (xi)     ACCURATE REPORTS. No Periodic Report (if prepared by any
     Seller, or to the extent that information contained therein was supplied by
     such Seller or by any Person, including TMM, on its behalf), information,
     exhibit, financial statement, document, book, record or report furnished or
     to be furnished by any Seller in connection with the Transaction Documents
     was or will be inaccurate in any material respect as of the date it was or
     will be dated or as of the date so furnished or contained or will contain
     any material misstatement of fact or omitted or will omit to state a
     material fact or any fact necessary to make the statements contained
     therein in light of the circumstances in which they were made not
     materially misleading.

                                       34
<Page>

               (xii)    NO IMMUNITY. Under the laws of Mexico none of the
     Sellers nor any of their property has 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).

               (xiii)   NO TAXES. With respect to non-residents of Mexico who
     are Eligible Owners, under current Mexican law, there is no tax on income
     or capital gains, and there is no withholding tax, net wealth tax, gift,
     estate or inheritance tax, registration tax, custom or stamp duty or other
     issuance or transfer tax or duty or other similar taxes or duties payable
     in Mexico or to any taxing authority thereof or therein in connection with
     (i) the authorization, issuance, sale and delivery of the Certificates,
     (ii) any payment made by any Obligor or the Servicer, including Collections
     or (iii) payments of the principal of or any premium, interest or other
     amounts on the Certificates by the Sellers, the Trustee or the Trust to a
     Certificateholder, other than the Mexican tax currently levied at the rate
     of (y) 4.9% for Eligible Owners which are Hacienda Banks, and (z) 15% for
     any other Eligible Owners on the payments of interests on the Certificates.
     For purposes of Mexican tax law, neither the Trust nor the Trustee's
     interest therein will be treated as a separate entity subject to taxation.

               (xiv)    TREASURY REGULATIONS. (A) Neither the sale of the
     Investor Certificates nor any Seller's use of the proceeds thereof as
     contemplated by the Transaction Documents violate any of the following
     regulations of the United States Treasury Department (31 C.F.R. Subtitle B,
     Chapter V, as amended): the Foreign Assets Control Regulations, the
     Transaction Control Regulations, the Cuban Assets Control Regulations, the
     Iranian Transactions Regulations, the Libyan Sanctions Regulations or the
     Iraqi Sanctions Regulations and (B) no Seller, nor any Affiliate of any
     Seller is (i) a country, territory, organization, person or entity named on
     the U.S. Treasury Department's Office of Foreign Assets Control ("OFAC")
     list, (ii) a person or entity that resides or has a place of business in a
     country or territory named on such lists or which is designated as a
     Non-Cooperative Jurisdiction by the Financial Action Task Force on Money
     Laundering, or, to the best knowledge of each Seller, whose funds are
     transferred from or through such a jurisdiction, (iii) a "Foreign Shell
     Bank" within the meaning of the Uniting and Strengthening America by
     Providing Appropriate Tools Required to Intercept and Obstruct Terrorism
     Act of 2001 (the "USA PATRIOT ACT"), i.e. a foreign bank that does not have
     physical presence in any country and that is not affiliated with a bank
     that has a physical presence and an acceptable level of regulation or
     supervision or (iv) a person or entity that resides in, or is organized
     under the laws of, a jurisdiction designated by the Secretary of Treasury
     under Section 311 or 312 of the USA PATRIOT ACT, as warranting special
     measures due to money laundering concerns.

               (xv)     ERISA.

                  (A)   Each Seller represents and warrants that it is not a
          "party-in-interest", as such term is defined in Section 3(14) of
          ERISA, or a "disqualified person", as such term is defined in Section
          4975(e)(2) of the Internal Revenue Code with respect to any "plan"
          within the meaning of Section 4975(e)(1) of the Code or any "employee
          benefit plan" within the meaning of Section 3(3) of

                                       35
<Page>

          ERISA (each, a "PLAN") except with respect to any plan sponsored,
          maintained or contributed to by any Seller with respect to its
          employees.

                  (B)   None of the Sellers is a member of a "controlled group"
          of corporations or other entities (as such term is defined in Section
          414(b) or (c) of the Internal Revenue Code) which also has as a member
          any United States corporation or other entity sponsoring an employee
          benefit plan (within the meaning of Section 3(3) of ERISA).

               (xvi)    REGULATORY STATUS. No Seller is an "investment company"
     or an "affiliated person" of, or "promoter" or "principal underwriter" for,
     an "investment company" required to be registered as such within the
     meaning of the Investment Company Act and the Trust is neither (i)
     registered under the Investment Company Act nor (ii) a common trust fund or
     similar fund excluded from the definition of investment company by virtue
     of section 3(c)(3) of the Investment Company Act. The consummation of the
     transactions contemplated hereby will not violate any provision of such Act
     or any rule, regulation or order of the Securities and Exchange Commission
     thereunder. No Seller is subject to regulation as a "Holding Company," an
     "affiliate" of a "Holding Company," or a "Subsidiary Company" of a "Holding
     Company", within the meaning of the Public Utility Holding Company Act of
     1935, as amended. Neither the Trust nor the Trustee is required, solely as
     a result of the transaction contemplated by the Transaction Documents, to
     register under the Investment Company Act or the Trust Indenture Act.

               (xvii)   COMPLIANCE WITH ALL REQUIREMENTS OF LAW. Each Seller is
     in compliance in all material respects with all Requirements of Law
     applicable to such Seller, except where the failure to be in compliance is
     not reasonably likely to result in a Material Adverse Effect.

               (xviii)  OBLIGATIONS PARI PASSU WITH INDEBTEDNESS. Each Seller's
     obligations under the Transaction Documents constitute direct, senior,
     unsecured, unsubordinated obligations of such Seller and rank at least PARI
     PASSU in order of payment and in all other respects with all direct,
     senior, unsecured, unsubordinated indebtedness of such Seller, except for
     such priorities and preferences as may be imposed by statute or regulation
     for taxes, wages or other statutorily or regulatorily preferred
     obligations.

               (xix)    LOCATION OF ASSETS AND MAJOR EXECUTIVE OFFICE. Each
     Seller's major executive office is as set forth in SECTION 10.5(a). No
     Seller has an office or place of business in the United States. No Seller
     has any assets in the United States, other than the stock of its U.S.
     subsidiaries, if any.

               (xx)     NO FRAUDULENT CONVEYANCE. None of the Sellers is
     entering into the Transaction Documents with the actual intent to hinder,
     delay or defraud its current or future creditors, nor does any Seller
     intend to or believe (i) that it will incur, as a result of entering into
     any Transaction Document to which it is or will be a party, debts beyond
     its ability to repay and (ii) that the execution of the Transaction
     Documents and the conveyance of the Purchased Receivables to the Trust, for
     the benefit of the Investor

                                       36
<Page>

     Certificateholders, is a transaction that may be conceived as fraudulent in
     regards to creditors, as such term is used by the Mexican Bankruptcy Law or
     any other applicable law or regulation protecting creditors rights
     generally.

               (xxi)    SOLVENCY. Each Seller is, and immediately after giving
     effect to the transactions occurring on each Closing Date will be, Solvent.

               (xxii)   INFORMATION SUPPLIED TO INVESTOR CERTIFICATEHOLDERS. The
     information furnished by or on behalf of TMM as Seller and as Sellers'
     Representative on behalf of the other Sellers and by each of the other
     Sellers to the Investor Certificateholders, the Trustee or their respective
     counsel or representatives in connection with any of the Transaction
     Documents or any transaction contemplated thereby does not, when taken as a
     whole, contain any untrue statement of material fact or omit to state any
     material fact necessary to make the statements herein or therein, in light
     of the circumstances under which they were made, not misleading in any
     material respect. There is no fact known to TMM or any other Seller that
     could reasonably be expected to have, individually or in the aggregate, a
     Material Adverse Effect that has not been disclosed herein, in the other
     Transaction Documents, or in a financial statement or other writing
     furnished to the Investor Certificateholders or the Trustee prior to the
     Document Closing Date.

               (xxiii)  NO LIENS. As of the Third Closing Date and after giving
     effect to the transactions to take place on such date, the Purchased
     Receivables are free from any and all liens, encumbrances, preferential
     rights or other restrictions or limitations or similar liabilities, except
     for such liens, encumbrances, preferential rights or other restrictions
     arising from any Transaction Document with respect to the Purchased
     Receivables unless otherwise disclosed by TMM on SCHEDULE 7.

               (xxiv)   COLLECTION STATUS. Except as may be indicated on
     SCHEDULE 8, the Purchased Receivables are current in their payment and are
     not past due.

               (xxv)    NO GENERAL SOLICITATION; OFFERS. Neither the Trust, TMM,
     any of the other Sellers, nor any of their Affiliates, nor any person
     (including, without limitation, any broker) acting on its or on their
     behalf, has engaged in any form of general solicitation or general
     advertising (within the meaning of Regulation D under the Securities Act)
     in connection with the offer or sale of the Series 2002-A Certificates and
     no offers or sales of such Series 2002-A Certificates were made in any
     state other than the States of New York, Delaware or New Jersey. Without
     limiting the foregoing, none of Citibank or any of its affiliates has acted
     as a "Broker-Dealer" or "Underwriter" (as those terms are defined in the
     Securities Act) or as an agent, arranger or in any other similar capacity
     to any of, the Trust, Trustee, any of the Sellers, the Series 2002-A
     Certificateholders, the Series 2002-A Purchaser or any of their respective
     affiliates in connection with the offer or sale of the Series 2002-A
     Certificates.

               (xxvi)   NO INTEGRATED OFFERING. Neither the Trust, TMM, any of
     the other Sellers, nor any of their Affiliates, nor any person (including,
     without limitation, any broker) acting on its or on their behalf has,
     directly or indirectly, made any offers or sales

                                       37
<Page>

     of any security or solicited any offers to buy any security, under
     circumstances that would require registration of any of the securities of
     such parties under the Securities Act or cause this offering of the Series
     2002-A Certificates to be integrated with prior offerings by the Trust,
     TMM, any of the other Sellers, or any of their Affiliates, for purposes of
     the Securities Act or any applicable stockholder approval provisions,
     including, without limitation, under the rules and regulations of any
     exchange or automated quotation system on which any of the securities of
     the Trust, TMM, any of the other Sellers, or any of their Affiliates, are
     listed or designated, nor will the Trust, TMM, any of the other Sellers,
     nor any of their Affiliates take any action or steps that would require
     registration of any of the Series 2002-A Certificates under the Securities
     Act or cause the offering of the Series 2002-A Certificates to be
     integrated with other offerings other than the offering and sale of the

          (b)     THE TRANSACTION DOCUMENTS. TMM represents on behalf of itself
and each other Seller (it being understood that any reference below in this
ARTICLE III to "Seller" when applicable to TMM shall also mean TMM in its role
as Guarantor, Sellers' Representative and, to the extent applicable, Servicer),
and each other Seller hereby represents and warrants, to the Trust and the
Trustee that, as of the Document Closing Date, the Initial Closing Date (unless
expressly stated to be only as of the Document Closing Date) and each subsequent
Closing Date, including the Third Closing Date:

                 (i)    Each of (a) the Transaction Documents has been duly
     executed and delivered and constitutes the legal, valid and binding
     obligations of TMM, each other Seller, Guarantor or TMM Multimodal to the
     extent that any such Person is a party thereto, enforceable against such
     Person in accordance with its terms, except as such enforceability may be
     limited by applicable bankruptcy, CONCURSO MERCANTIL, insolvency,
     reorganization, moratorium or other similar laws now or hereafter in effect
     affecting the enforcement of creditors' rights in general, or as such
     enforceability may be limited by general principles of equity (whether
     considered in a suit at law or in equity).

                 (ii)   Under Mexican law, (a) the transfer of the Purchased
     Receivables and the other Trust Assets from each Seller to the Trust
     pursuant to each of the Receivables Sale Agreements constituted a sale
     effective as of the Initial Closing Date, except for the "2002 Purchased
     Receivables" (as such term is defined in the First Amendment to PEMEX
     Receivables Sale Agreement) which constitute a sale effective as of the
     Second Closing Date, and (b) following such transfer in accordance with the
     terms of the Receivables Sale Agreements and this Master Trust Agreement,
     the Purchased Receivables, any monies outstanding in the Sweep Account, the
     Collection Account, the Peso Denominated Account, the Collection
     Subaccounts and the other Trust Assets will not constitute property or
     rights of any Seller or its Subsidiaries or Affiliates, but instead will be
     held by the Trust free and clear of any Lien of any Person except for (x)
     the interests of the Trustee, the Certificateholders and any Holder of a
     Subordinated Certificate, and (y) the interest of the Holders of the
     Sellers' Certificate.

                 (iii)  Under Mexican law, upon the Initial Closing Date, the
     Trust became the owner of the Purchased Receivables other than the "2002
     Purchased Receivables" (as defined in the First Amendment to PEMEX

     any monies outstanding in the Sweep Account, the Collection Account, the
     Collection Subaccount, the Peso Denominated Account and the other Trust

     any monies outstanding in the Sweep Account, the Collection Account, the
     Collection Subaccounts, the Peso Denominated Account and the other Trust
     Assets.

                 (iv)   No action, including, but not limited to, any other

     other than (w) the execution and delivery of this Master Trust Agreement
     and the Receivables Sale Agreements signed or ratified before a public
     notary or public broker, which signature or ratification has occurred prior
     to or concurrently herewith or, prior to or concurrently with the Initial
     Closing Date, (x) in the case of the Receivables Sale Agreements, an
     executed Acknowledgment from each Obligor, (y) in the case of the
     Receivables Sale Agreements and the Master Trust Agreement, the filing of
     UCC-1 financing statements in the proper jurisdiction naming each Seller as
     debtor and the Trustee, for the benefit of each Investor Certificateholder,
     as secured party, or (z) in lieu of (x), a notification to each Obligor
     that has not executed an Acknowledgment before two (2) witnesses of the
     transfer of the Purchased Receivables transferred by each such Obligor, is
     necessary to perfect the Trust's rights in and to the Purchased Receivables
     under New York and Mexican law.

                  (v)   All steps necessary or advisable to ensure the legality,
     validity, enforceability or admissibility in evidence of the Transaction
     Documents (other than the preparation of a Spanish translation of such
     document by a court approved translator in the event any legal proceedings
     in connection with or arising from such documents are brought in any court
     of Mexico and the approval of such translation by such court) in Mexico
     were taken prior to the Initial Closing Date, or as to documents required
     for the Third Closing Date will be taken on or before the Third Closing
     Date, and it is not necessary that such documents or any other document be
     filed or recorded with any court or other authority in Mexico or that any

     the property subject thereto or materially interfere with the ordinary
     conduct of the business of TMM or such Restricted Subsidiary or such other
     Seller or such consolidated Subsidiary;

                  (vi)  any attachment or judgment Lien, unless the judgment it

     PROVIDED that such Liens are limited to the asset so acquired and the

                  (xii) Liens securing Indebtedness owed to TMM or any of its
     Restricted Subsidiaries by any of its Restricted Subsidiaries;

                 (xiii) additional Liens ("ADDITIONAL LIENS") securing

<Page>

          (cc)    Except as otherwise provided herein, the Sellers shall not and
shall not permit any of their Subsidiaries to extend, amend or otherwise modify
the terms of any Purchased Receivable in a manner that adversely affects the
amount or collectibility of such Purchased Receivable except for discounts
negotiated for early payment thereof or other extensions, amendments or
modifications, in each case effected in accordance with TMM's Credit and
Collection Policies.

          (dd)    The obligations of the Sellers under any of the Transaction
Documents shall not be subject to any defense, counterclaim or right of set-off

provided in any Transaction Document to which it is a party.

OF ANY SELLER. None of the Sellers shall consolidate with, merge with or into,
or transfer, directly or indirectly by lease, assignment, sale or otherwise,
including, without limitation, as a result of the merger or consolidation of a
consolidated Subsidiary (or in the case of TMM a Restricted Subsidiary) with any
other Person (collectively, a "transfer"), all or substantially all of its
assets in one transaction or a series of related transactions to, any Person or
group of affiliated Persons or, in the case of any Seller other than TMM, permit
any of its consolidated Subsidiaries to, or in the case of TMM, permit any of
its Restricted Subsidiaries to, enter into any such transaction or transactions
if such transaction or transactions in the aggregate would result in a transfer
of all or substantially all of the assets of TMM and its Restricted
Subsidiaries, or such other Seller and its consolidated Subsidiaries, unless:

          (a)     In the case of a merger or consolidation, such Seller or TMM
shall be the continuing Person, or the Person formed by such consolidation or
merger or into which such Seller is merged or to which all or substantially all
of the properties and assets of such Seller are transferred or to which all of
the assets of TMM and its Restricted Subsidiaries on a consolidated basis are
transferred (the "surviving entity") shall be a Person organized and existing
under the laws of the United States of America, any State thereof or the
District of Columbia or Mexico and, prior to the effectiveness of such
transaction or transfer shall expressly assume, by a written instrument in form
and substance satisfactory to the Investor Certificateholders, all the
obligations of such Seller (and if such Seller is TMM, its obligations as
Guarantor and Sellers' Representative) under the Transaction Documents; PROVIDED
that a corporation at all times shall be a co-obligor together with the
continuing Person or transferee if the continuing Person or transferee is itself
not a corporation;

          (b)     immediately before and immediately after giving effect to such

          (c)     immediately after giving effect to such transaction, the
Consolidated Net Worth (as such term is defined in the Series 2001-A Supplement)

consolidation of or transfer by TMM, the surviving entity is equal to or greater
than the Consolidated Net Worth of TMM and its Restricted Subsidiaries
immediately prior to the transaction;

                                       48
<Page>

          (d)     immediately after giving effect to such transaction, TMM or
the surviving entity in the case of such a merger or consolidation of or
transfer by TMM could incur at least $1.00 of additional Indebtedness under each
of the Indentures; and

          (e)     prior to the effectiveness of such transaction or transfer,
Sellers' Representative shall deliver to the Trustee (i) an Officer's
Certificate (attaching the arithmetic computations to demonstrate compliance
with paragraph (c), if applicable) stating that such consolidation, merger,
sale, assignment, transfer or lease and written instrument of assumption comply
with this SECTION 3.3 and that all conditions precedent herein provided for
relating to such transactions have been complied with, (ii) opinions of counsel
(x) stating that such merger, consolidation or transfer and written instrument
of assumption comply with this SECTION 3.3 and (y) which are otherwise in form
and substance reasonably satisfactory to the Investor Certificateholders, (iii)
if such transaction or transfer relates to a Seller other than TMM, the Sellers'
Representative shall cause TMM to deliver a reaffirmation of the Guaranty and
(iv) if such transaction or transfer relates to TMM and TMM is not the surviving
entity, the Sellers' Representative shall cause such surviving entity to deliver
a new guaranty in form and substance substantially similar to EXHIBIT I.

     Section 3.4  INDEMNIFICATION BY TMM.

          (a)     Notwithstanding anything to the contrary contained in this
Master Trust Agreement or any Supplement, but except as set forth in the proviso
at the end of SECTION 3.4(b) below, TMM, on behalf of itself and each of the
other Sellers, shall be liable to all creditors of the Trust (but not to
Investor Certificateholders) for all liabilities of the Trust to the same extent
as it would be if the Trust constituted a partnership under New York law and any
Seller was a general partner thereof. Any such creditor of the Trust will be a
third party beneficiary of this SECTION 3.4(a).

          (b)     TMM, on behalf of itself and each of the other Sellers, shall
indemnify and hold harmless the Trustee, Paying Agent, each Certificateholder or
Certificate Owner (in its capacity as such), their permitted successors and
assigns (including owners of participation interests in Certificates granted by
a Certificateholder or Certificate Owner), and each of their respective
officers, directors, employees and agents (each, an "INDEMNIFIED PARTY") from
and against any loss, liability, judgment, damage, injury or claim other than
Taxes (except as expressly provided herein or in any Supplement) (including all
legal or other expenses reasonably incurred by an Indemnified Party in
connection with the investigation of, preparation for or defense of any claim,
action or proceeding, whether or not resulting in any liability) ("INDEMNIFIED
LOSSES") (whether on account of settlements or otherwise, and whether or not the
relevant Indemnified Party is a party to any action or proceeding that gives
rise to Indemnified Losses) suffered or sustained by reason of or in any way
arising out of or relating to (i) any of the Transaction Documents (which for
such purposes shall be deemed to also include the Original Transaction Documents
and the October 2002 Transaction Documents), any Obligor Agreement, any
Purchased Receivables or any of the transactions contemplated thereby, any
investigations, litigations or proceedings in connection therewith, any
amendment, modification, waiver, enforcement or remedy in respect thereto, or
any act or omission in connection therewith, (ii) acts, omissions or alleged
acts or omissions arising out of or in connection with the acceptance,
administration or performance of any Transaction Document or the use of proceeds
therefrom by

                                       49
<Page>

any Seller, including without limitation TMM in its capacity as Servicer,
Sellers' Representative and Guarantor, or the trusts hereunder and thereunder
and its duties hereunder or thereunder, (iii) any breach of any representation
or warranty or covenant of any Seller, including, without limitation, TMM in its
capacity as Servicer, Sellers' Representative or Guarantor contained in any
Transaction Document and (iv) fees (including without limitation all broker's or
finder's fees), acts, omissions or alleged acts or omissions arising out of or
in connection with the offer or solicitation of any Person to become a Series
2001-A Certificateholder or Series 2002-A Certificateholder; PROVIDED, HOWEVER,
that TMM shall not indemnify any Indemnified Party to the extent of any
Indemnified Losses which are found in a final judgment of a court of competent
jurisdiction to have been caused by the gross negligence or willful misconduct
by any Indemnified Party (or the gross negligence or willful misconduct on the
part of any of such Indemnified Party's officers, directors, employees or
agents); and PROVIDED FURTHER that the foregoing indemnity shall not be
construed to constitute a guarantee of payment of the Purchased Receivables or
to give rise to liability to TMM for non-payment of a Purchased Receivable by
any Customer Obligor to the extent any such guarantee or liability is excluded
pursuant to SECTION 2.2(b) above.

          (c)     All payments in respect of the Certificates shall be made
without set-off, counterclaim, fees, liabilities or similar deductions, and free
and clear of, and without any deductions or withholdings whatsoever, and TMM, on
behalf of itself and each of the other Sellers, shall indemnify Indemnified
Parties for, taxes, levies, duties or charges of any nature now or hereafter
imposed, levied, collected, withheld or assessed on an Indemnified Party by the
United States or Mexico or any political subdivision or taxing authority thereof
or therein ("COVERED TAXES"), except as provided below. Notwithstanding the
provisions of SECTION 3.4(b) above or any other provision to the contrary
herein, if any Seller or any agent thereof is required by law or regulation to
make any deduction or withholding for or on account of Covered Taxes, TMM, on
behalf of such Seller, shall pay to the Trust, for payment to the respective
Certificateholder and/or Certificate Owners, any Additional Amounts except that
no such Additional Amounts shall be payable and TMM shall have no obligation to
reimburse or indemnify a Certificateholder or Certificate Owner in respect of
(i) any Taxes imposed on any payment made to such Indemnified Party solely by
reason of the failure of such Indemnified Party to provide, in the time and
manner required under applicable law, regulations and administrative practice,
any documentation or certification requested by TMM or the Trustee and required
to make any claim for exemption from, or reduction of, withholding of any Taxes
to which it is otherwise entitled; PROVIDED, THAT (x) such Indemnified Party
shall be under no obligation to provide any documentation or certification to
TMM or the Trustee which such Indemnified Party deems, in such Indemnified
Party's reasonable judgment, to be confidential and (y) the completion,
execution and delivery of such documentation or certification will not result,
in the good faith reasonable determination of such Indemnified Party, in the
imposition on such Indemnified Party of (1) any additional material legal or
regulatory burden or (2) any additional material out-of-pocket costs which are
not paid by TMM or (3) any other material adverse consequences; (ii) Taxes that
would not have been imposed on the relevant Indemnified Party but for the
existence of any present or former connection (unrelated to the transactions
contemplated by the Transaction Documents) between such Indemnified Party (or an
Affiliate thereof) (or between a fiduciary, settlor or beneficiary of, or a
possessor of a power over, such Indemnified Party or Affiliate, but excluding
the Trustee, if such Indemnified Party or Affiliate is an estate or a trust, or
between a member or shareholder of such Indemnified Party or Affiliate, if

                                       50
<Page>

such Indemnified Party or Affiliate is a partnership or corporation) and the
jurisdiction imposing such Taxes or any political subdivision thereof,
including, without limitation, such Indemnified Party or Affiliate (or such
fiduciary, settlor, beneficiary, possessor, member or shareholder) being or
having been a citizen or resident or treated as a resident thereof, or being or
having been incorporated or organized therein, or being or having been engaged
in a trade or business therein, or being or having been engaged in activities or
transactions therein unrelated to those contemplated by the Transaction
Documents, or being or having been present therein, or having or having had a
permanent establishment therein, (iii) any Taxes that would not have been
imposed but for the breach by a Certificateholder or Certificate Owner of any
representation or warranty made by it in any Transaction Document or the failure
of such Certificateholder or Certificate Owner to observe or perform any
obligation of such Certificateholder or Certificate Owner under the Transaction
Documents, (iv) any Tax imposed by the federal government of the United States
of America, or by any state or local government or taxing authority located in
the United States of America, on or measured by the net income of such
Indemnified Party, by the jurisdiction in the United States under the laws of
which the Indemnified Party is organized or maintains an office, or by any
jurisdiction in the United States in which the Indemnified Party is subject to
such net income tax as a result of transactions or activities in such
jurisdiction unrelated to those contemplated by the Transaction Documents, (v)
any Tax imposed on an Indemnified Party by reason of either (A) the failure of
the certification made by such Indemnified Party on any form provided pursuant
to SECTION 3.4(d) below to be accurate and true in all material respects or (B)
the failure of such Indemnified Party to otherwise comply with SECTION 3.4(d),
unless any such failure would not have occurred but for a Change in Law that
occurs on or after the date that the Indemnified Party acquired its interest in
a Certificate, (vi) any Mexican Tax imposed on any assignee of a Certificate or
any holder or owner of a participation interest in a Certificate, that, in
either case, acquired its interest in a Certificate in violation of a transfer
restriction set forth in a Supplement to the extent such Mexican Tax exceeds the
Mexican Tax that would have been imposed on the assignor or grantor of such
interest absent such violation, or (vii) any Mexican Tax on any fees (which are
in addition to interest paid on the Certificates) paid by Purchaser to any
participant or assignee.

     As soon as reasonably practicable after the date of any payment by the
Sellers of any Covered Tax in respect of any Investor Certificate, but in any
case within 30 calendar days, the Sellers shall furnish to the Trustee for
delivery to the Certificate Owners, a certified copy of the original tax receipt
(if such a receipt has been issued and, if such tax receipt has not then been
issued, the Sellers shall furnish a certified copy thereof to the Trustee for
delivery to the Certificate Owners as soon as reasonably practicable after such
tax receipt is so issued, but in any case within thirty (30) calendar days
thereafter).

     The obligations of TMM under this SECTION 3.4(c) and under SECTION 3.4(b)
above shall survive the termination of the Trust, the sale or transfer of any
Certificate or sale or transfer of a participation interest in any Certificate
by any Certificateholder or Certificate Owner and the resignation or removal of
the Trustee.

          (d)     Each Certificateholder and Certificate Owner (and each Person
that acquires an interest in an Investor Certificate by assignment or
participation or other transfer) that is not a "United States person" as defined
in Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended, by its
acceptance of its Investor Certificate (or its interest therein)

                                       51
<Page>

covenants and agrees that it (or an intermediary which has provided a copy of
IRS form W-8IMY indicating that the intermediary holds the following forms) will
(i) provide to the Trustee and to the Sellers an appropriately executed copy of
Internal Revenue Service Form W-8ECI (or applicable successor form) certifying
that any payments made to or for the benefit of such Certificateholder,
Certificate Owner or other Person are effectively connected with the conduct of
a United States trade or business (or, alternatively, Internal Revenue Service
Form W-8BEN, but only if the applicable treaty described in such form provides
for a complete exemption from United States federal income Tax withholding in
respect of payments on the Certificates) or any successor form, (A) on or prior
to the date hereof (or, in the case of a Person acquiring an interest in an
Investor Certificate by assignment, participation or other transfer, on or prior
to the date of the relevant assignment or transfer or grant of participation),
(B) in each third subsequent year (or otherwise at the times required by
applicable regulations to establish a complete exemption from United States
federal income Tax withholding) prior to the first payment to be made to or for
the benefit of such Certificateholder, Certificate Owner or other Person in such
year, (C) upon the occurrence of any act by such Certificateholder, Certificate
Owner or other Person which would require the amendment or resubmission of any
such form previously provided hereunder, and (D) upon the request of the Trustee
or any Seller, upon the occurrence of any event (other than as a result of an
act by such Certificateholder, Certificate Owner or other Person) which would
require the amendment or resubmission of any such form previously provided
hereunder, and (ii) notify the Trustee and the Sellers if the certification made
on any form provided pursuant to this SECTION 3.4(d) is no longer accurate and
true in all material respects.

          (e)     In the event that any Seller has knowledge that it is or will
be required to, or there arises, in such Seller's reasonable opinion, a
substantial likelihood that such Seller will be required to, pay an Additional
Amount for or on account of any deduction or withholding of Tax pursuant to this
SECTION 3.4, such Seller will promptly notify the Trustee and each relevant
Certificateholder and/or Certificate Owner of the nature of such deduction or
withholding, and shall furnish such information to the Trustee and such
Certificateholder and/or Certificate Owner with respect to such deduction or
withholding as the Trustee or such Certificateholder and/or Certificate Owner
may reasonably request. In the event of any knowledge or opinion of any Seller
described in the preceding sentence, such Seller, TMM, the Trustee and each
relevant Certificateholder and/or Certificate Owner shall consult in good faith
to determine what may be required to avoid or reduce the withholding Tax, and
shall each use reasonable efforts to avoid or reduce such withholding Tax;
PROVIDED that nothing herein shall require the Trustee or any Certificateholder
and/or Certificate Owner to take any action which it in its reasonable judgment
determines may be adverse to it or, in the case of the Trustee, the interests of
the Trust.

     Section 3.5  GUARANTOR AS SELLERS' REPRESENTATIVE. Each Seller hereby
appoints TMM as its representative ("SELLERS' REPRESENTATIVE"), and the Sellers'
Representative hereby accepts such appointment, for receipt of any payment,
notice or other communication directed to the Sellers or any Seller pursuant to
any of the Transaction Documents and for the taking of any action (including the
making of all representations and covenants) which a Seller is required or
permitted to undertake or make pursuant to the Transaction Documents. The
Trustee may regard any notice or other communication pursuant to any Transaction
Document from the Sellers' Representative as a notice or communication from the
Sellers. Without limiting the foregoing, the Paying Agent shall make all
payments on the Distribution Date to the Sellers'

                                       52
<Page>

Representative, for the benefit of the applicable Seller or to an account
specified by the Sellers' Representative, and such payment to the Sellers'
Representative shall constitute payment to such Sellers for all purposes under
the Transaction Documents. TMM hereby accepts such appointment and agrees that
it shall not resign from its duties as the Sellers' Representative without the
written consent of the Trustee (acting pursuant to written instructions from the
Cumulative Required Investor Certificateholders (Super Majority). Each Seller
hereby covenants and agrees that each representation and warranty, covenant,
agreement and undertaking made in its name or on its behalf by the Sellers'
Representative shall be deemed for all purposes to have been made by such Seller
and shall be binding upon and enforceable against such Seller to the same extent
as if the same had been made directly by such Seller.

     Section 3.6  SELLERS MAY OWN CERTIFICATES. Any Seller may become the owner
of Certificates, subject to the eligibility requirements for Certificateholders
herein, but shall not participate in decisions made or instructions given to the
Trustee by the Certificateholders as a group hereunder.

     Section 3.7  SUBORDINATED CERTIFICATES. Notwithstanding anything in this
Master Trust Agreement and any related Supplement to the contrary, no Holder of
a Subordinated Certificate shall participate in decisions made or instructions
given to the Trustee by the Certificateholders, or any Series of
Certificateholders as a group hereunder or under any Supplement.

     Section 3.8  LIMITATIONS ON SELLERS', TMM MULTIMODAL'S LIABILITY; SELLERS'
RIGHT TO SUBROGATION AND REIMBURSEMENT.

          (a)     In an action or proceeding involving any state law, any
federal bankruptcy, insolvency or reorganization law, or any other law affecting
the rights of creditors generally, if the obligations of any Seller (other than
TMM) or TMM Multimodal (as "SUBSIDIARY TRANSFEROR") under the Transaction
Documents would otherwise be determined to be voidable, invalid or unenforceable
as a fraudulent transfer or otherwise as a result or on account of the amount of
such Seller's or TMM Multimodal's liability or obligations under the Transaction
Documents, then, notwithstanding any other provision hereof to the contrary, the
amount of such liability or obligation shall, without any further action of such
Seller, TMM Multimodal or any other Person, be automatically limited and reduced
to the highest amount which is valid and enforceable.

          (b)     In the event that any Purchased Receivables, or the value
thereof, are or are claimed to have been transferred or paid by a Subsidiary
Transferor to the Trustee or any payment by TMM Multimodal in satisfaction of
any obligations of TMM or any other Seller (the "AFFILIATE OBLIGATIONS"), such
Subsidiary Transferor shall be subrogated to the Trustee's rights against the
Guarantor under the Guaranty with respect to such Affiliate Obligations, and
shall have a right to reimbursement from the Guarantor with respect to such
Affiliate Obligations; PROVIDED that such right of subrogation and right to
reimbursement shall be subordinated in all respects to the rights of the Trustee
and the other beneficiaries named under the Guaranty, including, but not limited
to, the right to payment in full of all amounts payable thereunder.

     Section 4.1  ESTABLISHMENT OF ACCOUNTS AND ALLOCATIONS.

          (a)     THE COLLECTION ACCOUNT. The Trustee, (i) for the benefit of
the Certificateholders and the Trustee, shall establish and maintain in the name
of the Trustee, on behalf of the Trust, or cause to be established and
maintained with a New York State office or branch of a Qualified Institution, a
non-interest bearing segregated trust account (the "COLLECTION ACCOUNT") bearing
a designation clearly indicating that the funds deposited therein are held in
trust for the benefit of the Certificateholders and the Trustee and (ii) for the
benefit of the Certificateholders and the Trustee shall establish in the name of
the Trustee, on behalf of the Trust, a non-interest bearing segregated account
(the "SWEEP ACCOUNT") bearing a designation clearly indicating that the funds
deposited therein are held in trust for the benefit of the Certificateholders;
PROVIDED, HOWEVER, that upon the insolvency of the Qualified Institution where
the Sweep Account is maintained, the Sweep Account shall not be permitted to be
maintained with such Qualified Institution and upon the insolvency of the
Trustee, the Collection Account shall not be permitted to be maintained with the
Trustee. SCHEDULE 1-A sets forth the account number of the Sweep Account, the
account designation of such account and the name of the Qualified Institution
where the Sweep Account is maintained. SCHEDULE 1-B sets forth the account
number of the Collection Account, the account designation of such account and
the name of the institution with which such account is maintained. Pursuant to
the terms of the Control Agreement, all funds in the Sweep Account will be
transferred on a daily basis into the Collection Account pursuant to the wire
transfer instructions and at the times set forth on SCHEDULE 1-C. The Collection
Account shall be divided into individual subaccounts for each outstanding Series
(each, respectively, a "COLLECTION SUBACCOUNT" and, collectively, the
"COLLECTION SUBACCOUNTS"), each bearing a designation clearly indicating that
the funds deposited therein are held in trust for the benefit of the Trustee and
the Certificateholders of such Series with a depository institution or trust
company meeting the criteria provided in the related Supplement. The Trustee, on
behalf of the Trust, shall possess all right, title and interest in all funds on
deposit from time to time in the Collection Account and in all proceeds thereof.
The Collection Account shall be under the sole dominion and control of the
Trustee for the benefit of the Investor Certificateholders. Neither the Sellers
nor the Servicer, nor any Person or entity claiming by, through or under any
Seller or the Servicer, shall have any right, title or interest in (except to
the extent expressly provided under this Master Trust Agreement or any
Supplement), or any right to withdraw any amount from, the Collection Account.
Funds in the Collection Account shall not be invested. Funds in any Collection
Subaccount may not be invested except as provided in the related Supplement and
any earnings resulting from such investment shall be applied as provided in such
Supplement.

          (b)     THE PESO DENOMINATED ACCOUNT. The Trustee, for the benefit of
the Certificateholders and the Trustee, shall, with the cooperation of TMM,
establish and maintain in the name of the Trustee, on behalf of the Trust, at a
Mexico City, Federal District, office or branch of a Qualified Institution
selected by TMM (the "PESO QUALIFIED INSTITUTION") an interest

                                       54
<Page>

bearing segregated trust account (the "PESO DENOMINATED ACCOUNT") bearing a
designation clearly indicating that the funds deposited therein are held in
trust for the benefit of the Certificateholders and the Trustee; PROVIDED,
HOWEVER, that upon the insolvency of the Peso Qualified Institution, the Peso
Denominated Account shall not be permitted to be maintained with the Peso
Qualified Institution. SCHEDULE 1-D sets forth the account number of the Peso
Denominated Account, the account designation of such account and the name of the
institution with which such account has been established. The Trustee, on behalf
of the Trust, shall possess all right, title and interest in all funds on
deposit from time to time in the Peso Denominated Account and in all proceeds
thereof. The Peso Denominated Account shall be under the sole dominion and
control of the Trustee for the benefit of the Investor Certificateholders.
Neither the Sellers nor the Servicer, nor any Person or entity claiming by,
through or under any Seller or the Servicer, shall have any right, title or
interest in, or any right to withdraw any amount from, the Peso Denominated
Account. Funds in the Peso Denominated Account shall not be invested.

          (c)     CONVERSION OF PESOS INTO DOLLARS. Pursuant to the Conversion
Agreement, each time funds in the Peso Denominated Account reach the amount of
Ps. 250,000 (the "PESO THRESHOLD"), the Peso Qualified Institution shall
immediately convert all funds then deposited in the Peso Denominated Account
into Dollars and shall immediately, but in any case no later than 2:00 p.m. New
York City time on the day such conversion is initiated, deposit (by means of a
wire transfer as set forth on SCHEDULE 1-C) the resulting Dollar amount into the
Collection Account. The Peso Qualified Institution shall convert the Pesos
deposited in the Peso Denominated Account into Dollars each time funds deposited
therein reach the Peso Threshold. For the conversion of Pesos deposited in the
Peso Denominated Account into Dollars for deposit as provided herein, the Peso
Qualified Institution, pursuant to the terms of the Conversion Agreement, shall
utilize the rate of exchange (net of fees or other charges) of Pesos into
Dollars that such Peso Qualified Institution determines, on the date of the
corresponding conversion, to be its fixed rate of exchange of Pesos into
Dollars. In the event that at any time such fixed rate of exchange of Pesos into
Dollars is not available for any reason, the Peso Qualified Institution shall
use the rate of exchange which the Peso Qualified Institution uses as the
applicable rate of exchange of Pesos into Dollars for its best corporate
clients.

          (d)     QUALIFIED INSTITUTION. If the Trustee ceases to be a
"Qualified Institution", then the Trustee shall (i) provide each Enhancement
Provider and the Servicer with prompt written notice that it is no longer a
"Qualified Institution" and (ii) transfer the funds deposited in each of the
accounts in the manner directed in writing by the Cumulative Required Investor
Certificateholders within 10 Business Days of the day on which the Trustee
ceased to be a "Qualified Institution".

          (e)     SERVICER'S DIRECTION TO TRUSTEE. The Servicer agrees to give
written direction in a timely manner to the Trustee to apply all Collections
with respect to the Purchased Receivables and to make all other applications,
allocations and distributions, in each case in the manner described in this
ARTICLE IV and in the related Supplement with respect to each outstanding
Series.

          (f)     ALLOCATIONS WITH RESPECT TO EACH OUTSTANDING SERIES. On or
before 4:00 p.m. New York City time on each Business Day, the Trustee, in
accordance with the report delivered for such day pursuant to SECTION 8.1(b)
below, shall withdraw from funds on deposit in

                                       55
<Page>

the Collection Account and deposit in each Collection Subaccount of each
outstanding Series an amount equal to the product obtained by multiplying the
Series Percentage for such Series times the amount on deposit in the Collection
Account on such day. All such amounts deposited in such Collection Subaccounts
of such Series shall be distributed in accordance with the applicable
Supplement(s).

     Section 4.2  RECEIVABLE SHORTFALL PAYMENTS.

                  (a)    (i) If Collections received by the Trust in any
     Collection Period are less than the Aggregate Required Coverage Amounts for
     such Collection Period, then Sellers' Representative shall pay to the
     Trust, by wire transfer into the Collection Account of immediately
     available funds in Dollars, on the immediately succeeding Transfer Date,
     the excess of such Aggregate Required Coverage Amounts over such
     Collections.

                  (ii)   If, in any Collection Period, the Sellers generate
     Eligible Purchased Receivables (excluding all Excess Receivables) having an
     aggregate Owed Amount at the time of their origination in an amount less
     than the Aggregate Required Coverage Amounts for such Collection Period,
     then Sellers' Representative shall pay to the Trust, by wire transfer into
     the Collection Account of immediately available funds in Dollars, on the
     immediately succeeding Transfer Date, such excess of the Aggregate Required
     Coverage Amounts over such Owed Amounts based on the Servicer Report
     delivered pursuant to SECTION 4.2(c) below.

          (b)     With respect to any Eligible Purchased Receivables generated
in any Collection Period, if, as a result of any reductions in the Owed Amount
of such Eligible Purchased Receivables (as a result of customer disputes,
negotiated discounts for early payment or otherwise, but not as a result of
reductions arising from charge-offs), on the Determination Date next succeeding
such Collection Period it is determined pursuant to SECTION 4.2(c) below that
the sum of such reduced Owed Amounts plus the amount of Collections on such
Purchased Receivables is less than the Aggregate Required Coverage Amounts for
such Collection Period, the Sellers' Representative shall pay the Trust, by wire
transfer into the Collection Account of immediately available funds in Dollars,
on such Transfer Date, such shortfall based on the Servicer Report delivered
pursuant to SECTION 4.2(d) below.

          (c)     In calculating any Receivable Shortfall Payment for any
Collection Period in accordance with SECTION 4.2(b) above, the Servicer shall
monitor each Eligible Purchased Receivable in the group of Eligible Purchased
Receivables generated in any Collection Period and shall review, in conjunction
with the Trustee, any Eligible Purchased Receivable that remains unpaid longer
than thirty (30) days past its due date (as set forth on the related invoice).
The Trustee, after consulting with the Servicer, shall reasonably determine
whether such Eligible Purchased Receivable has not been paid due to
credit-related defaults by Customer Obligors or due to customer disputes,
negotiated discounts for early payment or other reasons unrelated to the credit
of the applicable Customer Obligor. Any Eligible Purchased Receivable determined
not to have been paid due to credit-related defaults shall be deemed to be a
charge-off, for purposes of calculating the Receivable Shortfall Payment due.

<Page>

          (d)     On each Determination Date, the Servicer shall calculate the
Receivable Shortfall Payments due pursuant to SECTION 4.2(a) or (b) above, shall
set forth its calculations with respect to Receivable Shortfall Payments, or if
no Receivable Shortfall Payment is due, so indicate with such supporting
calculations, on the certificate (a "SERVICER REPORT") of a Responsible Officer
in the form of EXHIBIT M, and shall deliver the Servicer Report to the Trustee,
the Paying Agent and the Sellers.

hereof, including, without limitation, the right to receive Collections and
other amounts at the time and in the amounts specified in the applicable

Certificates on the applicable Closing Date, upon delivery to it of the
following: (i) a Supplement satisfying the criteria set forth in SECTION 5.9(b)
below executed by the Sellers and specifying the Principal Terms of such Series,
(ii) Opinions of Counsel to the effect that (A) the newly issued Series of
Investor Certificates will be treated (x) as a sale of the Purchased Receivables

United States federal income tax purposes and for Mexican tax purposes, and (B)
there is no tax on the sale of the Purchased Receivables or on payments on the
Certificates, other than the Mexican withholding tax levied at the rate of 4.9%

adversely affect the United States federal income tax or Mexican income tax
characterization (including any withholding tax characterization) of any
outstanding Series of Investor Certificates or result in the Trust being subject
to United States federal or Mexican tax at the entity level, and (iv) any
additional items required by the terms of the applicable Supplement or requested

and substance reasonably satisfactory to the Trustee.

party if the Trustee determines after consultation with the Servicer that such
party has failed to perform its obligations under this Master Trust Agreement in
any material respect. The Trustee shall be permitted to resign as Transfer Agent
and Registrar upon 30 days written notice to the Seller and the Servicer;
PROVIDED, HOWEVER, that such resignation shall not be effective and the Trustee

     Regulation S, a certification to that effect from such Holder in
     substantially the form of EXHIBIT F-2 hereto;

                  (iv)   if such Certificate is being transferred in reliance on
     another exemption from the registration requirements of the Securities Act,

     of EXHIBIT F-1 hereto and an Opinion of Counsel to such Holder to the
     effect that such transfer is in compliance with the Securities Act in
     substantially the form of EXHIBIT G hereto; or

represented by the Certificates so exchanged, in the manner specified in the
Supplement for such Series upon surrender of the Bearer Certificates to be
exchanged at an office or agency of the Transfer Agent and Registrar located
outside the United States, as specified in the related Supplement. Each Bearer
Certificate surrendered pursuant to this SECTION 5.3 shall have attached thereto
(or be accompanied by) all unmatured Coupons, PROVIDED that any Bearer
Certificate to be exchanged for a Registered Certificate so surrendered after

Date need not have attached the Coupons related to such Distribution Date.

     The preceding provisions of this SECTION 5.3 notwithstanding, the Transfer
Agent and Registrar shall not be required to register the transfer or exchange
of any Investor Certificate of any Series for a period of fifteen (15) days
preceding the due date for any payment with respect to the Investor Certificates
of such Series.

     Unless otherwise provided in the related Supplement, no service charge
shall be made for any registration of transfer or exchange of Investor
Certificates, but the Transfer Agent and Registrar may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer or exchange of Investor Certificates.

     All Investor Certificates (together with any Coupons attached to Bearer
Certificates) surrendered for registration of transfer or exchange shall be
canceled by the Transfer Agent and Registrar and disposed of in the Trustee's
normal and customary manner. The Trustee shall cancel and dispose of the Global
Certificate upon its exchange in full for Definitive Certificates and shall

pledge its interest in all of a portion of such Subordinated Certificate to any
Person, other than to TMM.

registration of transfer of Registered Certificates containing a legend relating
to the restrictions on transfer of such Registered Certificates (which legend
shall be as set forth in the Supplement relating to such Investor Certificates)
shall be effected only if the conditions set forth in such related Supplement
are satisfied.

     Whenever a Registered Certificate containing the legend set forth in the
related Supplement is presented to the Transfer Agent and Registrar for
registration of transfer, the Transfer Agent and Registrar shall promptly seek
instructions from the Servicer regarding such transfer. The Transfer Agent and
Registrar and the Trustee shall be entitled to receive written instructions
signed by a Responsible Officer of the Servicer prior to registering any such
transfer or authenticating new Registered Certificates, as the case may be. The
Servicer hereby agrees to indemnify the Transfer Agent and Registrar and the
Trustee and to hold each of them harmless against any loss, liability or expense
incurred without gross negligence or bad faith on their part arising out of or
in connection with actions taken or omitted by them in reliance on any such
written instructions furnished pursuant to this SECTION 5.3(d).

U.S. Registered Certificates and Regulation S Certificates, and if a Holder of a
U.S. Registered Certificate or a Certificate Owner holding a beneficial interest
in a U.S. Registered Certificate wishes at any time to transfer its interest in
such U.S. Registered Certificate to a Person who wishes to take delivery thereof
in the form of an interest in a Regulation S Certificate, such Holder or
Certificate Owner may, subject to the rules and procedures of The Depository
Trust Company and the provisions of this SECTION 5.3(e), transfer or cause the
transfer of such interest in such U.S. Registered Certificate for an equivalent
beneficial interest in the Regulation S Certificate. Upon receipt by the
Transfer Agent and Registrar of (i) instructions given in accordance with the
procedures of The Depository Trust Company from an agent member directing the
Transfer Agent and Registrar to credit or cause to be credited a beneficial
interest in the Regulation S Certificate in an amount equal to the interest in
the corresponding U.S. Registered Certificate to be transferred, (ii) a written
order given in accordance with the procedures of The Depository Trust Company by
the transferee of such interest in the U.S. Registered Certificate to be
transferred containing information regarding the account to be credited with
such increase and the name of such account, and (iii) such other certifications
as are required pursuant to SECTION 5.3(a) above, the Transfer Agent and
Registrar shall record in the Certificate Register a reduction of the
Certificate Balance of such U.S. Registered Certificate by the aggregate
principal amount of the interest in such U.S. Registered Certificate to be so
transferred and an increase of the Certificate Balance of such Regulation S
Certificate, and shall instruct The Depository Trust Company or its nominee to
make corresponding changes to its records in respect of such U.S. Registered
Certificate and Regulation S Certificate.

          (f)     If Investor Certificates of a Series are issued in the form of
U.S. Registered Certificates and Regulation S Certificates, and if a Certificate
Owner holding a beneficial interest in a Regulation S Certificate wishes at any
time to transfer its interest in such Regulation S Certificate to a Person who
wishes to take delivery thereof in the form of an

                                       63
<Page>

interest in a U.S. Registered Certificate, such Certificate Owner may, subject
to the rules and procedures of Euroclear or Clearstream and The Depository Trust
Company, as applicable, and the provisions of this SECTION 5.3(f), transfer or
cause the transfer of such interest in such Regulation S Certificate for an
equivalent interest in a U.S. Registered Certificate. Upon receipt by the
Transfer Agent and Registrar of (i) instructions given in accordance with the
procedures of Euroclear or Clearstream and The Depository Trust Company, as
applicable, directing the Transfer Agent and Registrar to credit or cause to be
credited a beneficial interest in a U.S. Registered Certificate in an amount
equal to the interest in the Regulation S Certificate to be transferred, (ii) a
written order given in accordance with the procedures of The Depository Trust
Company by the transferee of such interest in the Regulation S Certificate to be
transferred containing information regarding the account to be debited with such
decrease and the name of such account and (iii) such other certifications as are
required pursuant to SECTION 5.3(a) above, the Transfer Agent and Registrar
shall record in the Certificate Register a reduction of the Certificate Balance
of such Regulation S Certificate by the aggregate principal amount of the
interest in such Regulation S Certificate to be so transferred or an increase of
the Certificate Balance of a U.S. Registered Certificate, as the case may be, in
the amount of the interest in the corresponding Regulation S Certificate
transferred, and shall instruct The Depository Trust Company or its nominee to
make corresponding changes to its records in respect of such Regulation S
Certificate and U.S. Registered Certificate, if applicable.

     Section 5.4  MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES. If (a) any
mutilated Certificate (together, in the case of Bearer Certificates, with all
unmatured Coupons, if any, pertaining thereto) is surrendered to the Transfer
Agent and Registrar, or the Transfer Agent and Registrar receives evidence to
its satisfaction of the destruction, loss or theft of any Certificate and (b)
there is delivered to the Transfer Agent and Registrar and the Trustee such
security or indemnity as may be required by them to save each of them harmless,
then, in the absence of a BONA FIDE purchaser having possession of such
Certificate, the Trustee shall execute and authenticate and (unless the Transfer
Agent and Registrar is different from the Trustee, in which case the Transfer
Agent and Registrar shall) deliver (in compliance with applicable law), in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like tenor and in an aggregate amount equal to
the portion of the Certificate Balance represented by such mutilated, destroyed,
lost or stolen Certificate. In connection with the issuance of any new
Certificate under this SECTION 5.4, the Trustee or the Transfer Agent and
Registrar may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee and the Transfer Agent
and Registrar) connected therewith. Any duplicate Certificate issued pursuant to
this SECTION 5.4 shall constitute complete and indefeasible evidence of
ownership in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

     Section 5.5  PERSONS DEEMED OWNERS. Prior to due presentation of a
Certificate (other than a Bearer Certificate) for registration of transfer, the
Trustee, the Paying Agent, the Transfer Agent and Registrar and any agent of any
of them may treat the Person in whose name any Certificate is registered as the
owner of such Certificate for the purpose of receiving distributions, or for any
other deliveries (including but not limited to notices pursuant to SECTION 10.5)
pursuant to this Master Trust Agreement and the related Supplement, and none of
the Trustee, the Paying Agent, the Transfer Agent and Registrar nor any agent of
any of them shall

                                       64
<Page>

be affected by any notice to the contrary; PROVIDED, HOWEVER, that in
determining whether the holders of Investor Certificates evidencing the
requisite Certificate Balance have given any request, demand, authorization,
direction, notice, consent or waiver hereunder and for purposes of the
definitions of "Cumulative Required Investor Certificateholders", "Cumulative
Required Investor Certificateholders (Super Majority)", "Series Required
Investor Certificateholders" and "Series Required Investor Certificateholders
(Super Majority)", Certificates owned by the Sellers, the Servicer, or any
Affiliate thereof and Subordinated Certificates held by any Subordinated
Certificate Purchaser shall be disregarded and deemed not to be outstanding,
except that, in determining whether the Trustee shall be protected in relying
upon any such request, demand, authorization, direction, notice, consent or
waiver, only Investor Certificates which a Responsible Trustee Officer in the
Corporate Trust Office of the Trustee knows to be so owned shall be so
disregarded.

     In the case of a Bearer Certificate, the Trustee, the Paying Agent, the
Transfer Agent and Registrar and any agent of any of them may treat the bearer
of a Bearer Certificate or Coupon as the owner of such Bearer Certificate or
Coupon for the purpose of receiving distributions under this Master Trust
Agreement and the related Supplement, and neither the Trustee, the Paying Agent,
the Transfer Agent and Registrar nor any agent of any of them shall be affected
by any notice to the contrary.

     Section 5.6  APPOINTMENT OF PAYING AGENT.

          (a)     A paying agent (the "PAYING AGENT") shall make distributions
to Investor Certificateholders from the appropriate account or accounts
maintained for the benefit of Certificateholders as specified in the related
Supplement for any Series pursuant to ARTICLE IV hereof. The Paying Agent shall
have the revocable power to withdraw funds from such appropriate account or
accounts for the purpose of making distributions referred to above. The Trustee
may revoke such power and remove the Paying Agent, in its sole discretion. The
Paying Agent, unless the Supplement with respect to any Series states otherwise,
shall initially be the Person acting as the Trustee. The Trustee shall be
permitted to resign as Paying Agent upon thirty (30) days written notice to the
Servicer and Sellers' Representative effective only upon the appointment of
another Paying Agent. In the event that the Trustee shall cease to be the Paying
Agent, the Cumulative Required Investor Certificateholders shall appoint a
successor to act as Paying Agent (which shall be a bank or trust company). The
Trustee shall cause such successor Paying Agent or any additional Paying Agent
appointed by the Trustee to execute and deliver to the Trustee an instrument in
which such successor Paying Agent or additional Paying Agent shall agree with
the Trustee that as Paying Agent, such successor Paying Agent or additional
Paying Agent will hold all sums, if any, held by it for payment to the Investor
Certificateholders in trust for the benefit of the Investor Certificateholders
entitled thereto until such sums shall be paid to such Certificateholders. The
Paying Agent shall return all unclaimed funds to the Collection Account or such
other Series Account established pursuant to the Supplement with respect to any
Series at the times and in the manner provided in the related Supplement and
upon removal of a Paying Agent, such Paying Agent shall return all funds in its
possession to the Collection Account or such other account established pursuant
to the Supplement with respect to any Series at the times and in the manner
provided in the related Supplement. The provisions of SECTIONS 8.1, 8.2 and 8.3
below shall apply to the Trustee also in its roles as Paying Agent and Transfer
Agent and Registrar for so long as the Trustee shall act as Paying Agent or
Transfer Agent and

                                       65
<Page>

Registrar. Any reference in this Master Trust Agreement to the Paying Agent
shall include any co-paying agent unless the context requires otherwise.

     If specified in the related Supplement for any Series, so long as the
Investor Certificates of such Series are outstanding, the Servicer shall appoint
a co-paying agent in New York City reasonably acceptable to the Sellers for such
Series (for Registered Certificates only) or any other city designated in such
Supplement which, if and so long as any Series of Investor Certificates is
listed on the Luxembourg Stock Exchange or other stock exchange and such
exchange so requires, shall be in Luxembourg or the location required by such
other stock exchange.

          (b)     The Trustee shall cause the Paying Agent (other than itself)
to execute and deliver to the Trustee an instrument whereby such Paying Agent
shall agree with the Trustee that such Paying Agent will hold all sums, if any,
held by it for payment to the Certificateholders in trust for the benefit of the
Certificateholders entitled thereto until such sums shall be paid to such
Certificateholders and shall agree, and if the Trustee is the Paying Agent it
hereby agrees, that it shall comply with all requirements of the Internal
Revenue Code regarding the withholding by the Trustee of payments in respect of
United States income taxes due from Investor Certificateholders or Certificate
Owners and will, where required to avoid withholding of Taxes, obtain the
following from each Certificateholder that is not a "United States person" as
defined in Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended
(or a copy of IRS Form W-8IMY from an intermediary who holds such forms), such
forms, documents, certificates and other documentation as may be required under
the Code and applicable regulations to establish an exemption from withholding
of Taxes, including, without limitation:

                  (i)    IRS Form W-8BEN or successor form signed under
     penalties of perjury by the beneficial owner of Certificates stating that
     the Certificateholder or Certificate Owners is not a U.S. person and
     providing such Certificateholder's name and address; or

                  (ii)   IRS Form W-8BEN or successor form signed by the
     beneficial owner of Certificates or such owner's agent claiming exemption
     from withholding under an applicable tax treaty; or

                  (iii)  IRS Form W-8ECI or successor form signed by the
     beneficial owner of Certificates or such owner's agent claiming exemption
     from withholding of tax on income connected with the conduct of a trade or
     business in the U.S., pursuant to the applicable procedures in effect at
     the relevant time.

          (c)     The Trustee shall also obtain from all Certificateholders
(other than Certificateholders that are corporations, tax-exempt organizations,
qualified pension and profit-sharing trusts, individual retirement accounts or
nonresident aliens and that, in each case, establish an exemption from backup
withholding in accordance with applicable U.S. tax regulations) under penalties
of perjury, a certificate on IRS Form W-9 containing the holder's name, address,
correct federal taxpayer identification number and a statement that such
Certificateholder is not subject to backup withholding. Prior to each
Distribution Date occurring after the Servicer determines that any Taxes, other
than U.S. withholding taxes, are imposed on

                                       66
<Page>

payments from the Trust to the Certificateholders, the Servicer shall promptly
furnish to the Trustee a certificate of a Responsible Officer of the Servicer
specifying the amount required to be deducted or withheld on payments to
Certificateholders on any of the Certificates due on such Distribution Date for
or on account of any Taxes, other than U.S. withholding taxes, imposed on
payments to be made to any Certificateholder and the Trustee or the Paying Agent
shall cause such amount to be paid to the appropriate governmental authorities.
The Sellers' Representative (in its capacity as Servicer, if it is the Servicer)
agrees to indemnify each of the Trustee and Paying Agent for and to hold each
harmless against any loss, liability or reasonable expense incurred without
gross negligence, negligence in the handling of funds or willful misconduct on
its part, arising out of or in connection with actions taken or not taken by it
in reliance on any certificate furnished pursuant to SECTION 5.6(b) or this
SECTION 5.6(c) or the failure to furnish any such certificate. The obligation of
the Servicer under the preceding sentence shall survive payment of all the
Certificates, the satisfaction and discharge of this Master Trust Agreement and
the resignation or removal of the Trustee and any Paying Agent.

     Section 5.7  ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND ADDRESSES.

          (a)     The Trustee will furnish or cause to be furnished by the
Transfer Agent and Registrar to the Servicer or the Paying Agent, with a copy to
Sellers' Representative, within five (5) Business Days after receipt by the
Trustee of a request therefor from the Servicer or the Paying Agent,
respectively, in writing, a list of the names and addresses of the Investor
Certificateholders (other than Bearer Certificateholders) as of the most recent
Record Date for payment of distributions to Investor Certificateholders.

          (b)     Unless otherwise provided in the related Supplement, at any
time after Definitive Certificates have been issued with respect to a Series, if
the Holders of Investor Certificates of such Series evidencing not less than 10%
of the Certificate Balance of such Series (the "APPLICANTS") apply in writing to
the Trustee and such application states that the Applicants desire to
communicate with other Investor Certificateholders of such Series or, if such
Applicant certifies that it is necessary for it to communicate with other
Investor Certificateholders of another Series with respect to an amendment,
consent or waiver, another Series, with respect to their rights under this
Master Trust Agreement or under the Investor Certificates and is accompanied by
a copy of the communication which such Applicants propose to transmit, then the
Trustee, after having been adequately indemnified by such Applicants for its
costs and expenses and having given to the Servicer a copy of such application
and proposed communication, shall afford or shall cause the Transfer Agent and
Registrar to afford such Applicants access during normal business hours to the
most recent list of Certificateholders (other than Bearer Certificateholders) of
such Series or, if applicable, such other Series, held by the Trustee, within a
reasonable time but in any event not to exceed ten (10) Business Days after the
receipt of such application. Such list shall be as of a date no more than
forty-five (45) days prior to the date of receipt of such Applicants' request.
Every Certificateholder, by receiving and holding a Certificate, agrees with the
Trustee that neither the Trustee, the Transfer Agent and Registrar, nor any of
their respective agents shall be held accountable by reason of the disclosure of
any such information as to the names and addresses of the Certificateholders
hereunder, regardless of the source from which such information was obtained.

                                       67
<Page>

          (c)     Unless otherwise provided in the related Supplement, if the
Depository with respect to any Series of Certificates has procedures for
providing to the Certificate Owners of such Series a list of the other
Certificate Owners of such Series and, at any time, the Certificate Owners whose
Book-Entry Certificates evidence beneficial interests in Investor Certificates
of such Series aggregating not less than 10% of the Certificate Balance of such
Series deliver to the Trustee a written application (containing a certification
by an officer of each such Certificate Owner stating that such applicant is a
Certificate Owner, on which certification the Trustee may conclusively rely to
establish that such party is a Certificate Owner) and such application states
that such Certificate Owners desire to communicate with other Certificate Owners
of such Series with respect to their rights under this Master Trust Agreement or
under the Investor Certificates and is accompanied by a copy of the
communication which such Certificate Owners propose to transmit, then the
Trustee, after having been adequately indemnified by such Certificate Owners for
its costs and expenses and having given to the Servicer a copy of such
application and proposed communication, shall request the Depository to deliver
to such Certificate Owners a list of the other Certificate Owners of such Series
holding through the Depository.

     Section 5.8  AUTHENTICATING AGENT.

          (a)     The Trustee may appoint one or more authenticating agents with
respect to the Certificates which shall be authorized to act on behalf of the
Trustee in authenticating the Certificates in connection with the issuance,
delivery, registration of transfer, exchange or repayment of the Certificates.
Whenever reference is made in this Master Trust Agreement to the authentication
of Certificates by the Trustee or the Trustee's certificate of authentication,
such reference shall be deemed to include authentication on behalf of the
Trustee by an authenticating agent and a certificate of authentication executed
on behalf of the Trustee by an authenticating agent.

          (b)     Any institution succeeding to the corporate agency business of
an authenticating agent shall continue to be an authenticating agent without the
execution or filing of any paper or any further act on the part of the Trustee
or such authenticating agent.

          (c)     An authenticating agent may at any time resign by giving
written notice of resignation to the Trustee and to the Sellers. The Trustee may
at any time terminate the agency of an authenticating agent by giving notice of
termination to such authenticating agent and to the Sellers. Upon receiving such
a notice of resignation or upon such a termination, the Trustee may appoint a
successor authenticating agent. Any successor authenticating agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an authenticating agent.

          (d)     The Trustee agrees to pay each authenticating agent from time
to time reasonable compensation for its services under this SECTION 5.8, and the
Trustee shall be reimbursed for such fees by the Sellers.

          (e)     The provisions of SECTIONS 8.1 and 8.2 below shall be
applicable to any authenticating agent.

                                       68

          (f)     Pursuant to an appointment made under this SECTION 5.8, the
Certificates may have endorsed thereon, in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

     This is one of the certificates described in the Master Trust Agreement.

                              --------------------------------------------------
                              as Authenticating Agent for the Trustee,

                              By
                                ------------------------------------------------

     Section 5.9  TENDER OF SELLERS' CERTIFICATE.

          (a)     The Holder of the Sellers' Certificate may tender the Sellers'

issued Series of Investor Certificates to new Investor Certificateholders and
except with respect to the initial Series of Investor Certificates issued
hereunder, reissued Sellers' Certificate to be reissued to the Sellers (any such
tender, an "EXCHANGE"). The Holder of the Sellers' Certificate may perform an
Exchange by notifying the Trustee, in writing at least three (3) Business Days

Initial Certificate Balance), which amount must meet all applicable Receivables
Coverage Ratio and Generation Coverage Ratio tests approved by the Series

SECTION 5.2(b) above with respect to such new Series, (ii) the applicable
Enhancement, if any, (iii) the agreement, if any, executed by the Sellers and
the Enhancement Provider, pursuant to which the Enhancement Provider agrees to
provide the Enhancement, if any, with respect to such Series, (iv) the existing
Sellers' Certificate and (v) the approval of each Investor Certificateholder as
required pursuant to SECTION 5.9(c). Upon satisfaction of such conditions, the
Trustee shall cancel such existing Sellers' Certificate and execute,
authenticate and deliver such new Series of Investor Certificates and a new
Sellers' Certificate, dated the Exchange Date.

          (b)     In conjunction with an Exchange, the parties hereto shall
execute a Supplement agreeable to such parties, which shall specify the relevant
terms with respect to any Series of Investor Certificates, which may include
without limitation: (i) its name or designation, (ii) its Initial Certificate
Balance or the method of calculating its Initial Certificate Balance, (iii) the
Certificate Rate (or formula for the determination thereof), (iv) the Closing

such account, (ix) the terms of any Enhancement with respect to such Series and
the Enhancement Provider, if applicable, (x) the terms on which the Certificates
of such Series may by offered and sold, repurchased by each Seller, subject to
any restrictions then set forth in the Transaction Documents, or resold or
remarketed to other investors, (xi) the Expected Final Distribution Date of the
Series, (xii) any deposit into any Series Account maintained for the benefit of
the Trustee and the Certificateholders of such Series, (xiii) the number of
Classes of such Series, and if more than one Class, the rights and priorities of
each such Class, (xiv) the extent to which the Investor Certificates will be
issuable in temporary or permanent global form, and in such case, the Depository
for such Global Certificate or Certificates, the terms and conditions, if any,
upon which such Global Certificate may be exchanged in whole or in part for
Definitive Certificates, and the manner in which any interest payable on a
temporary or Global Certificate will be paid, (xv) whether the Investor
Certificates may be issued in bearer form and any limitations imposed thereon,
(xvi) whether any fees will be included in the funds available to Investor
Certificateholders of such Series, (xvii) the priority of any Series with
respect to any other Series, (xviii) the rights of the Holder of the Sellers'
Certificate that have been transferred to the Investor Certificateholders of
such Series, (xix) the principal payment period with respect to such Series and
(xx) any other relevant terms of such Series (all such terms, the "PRINCIPAL
TERMS" of such Series). So long as the Series 2001-A Certificates are
outstanding, neither the Series 2002-A Certificates nor any other Series or the
applicable Supplement for any such Series issued after the Initial Closing Date
shall provide for (i) an earlier Expected Final Distribution Date or other
maturity, (ii) a greater level of amortization, (iii) any additional or more
restrictive covenants or Rapid Amortization Events, (iv) any additional rights
or remedies or (v) additional optional or obligatory repurchase rights, than
those set forth in the Series 2002-A Supplement in the form attached hereto as
EXHIBIT P.

          (c)     No new Series shall be issued after the initial Series unless
approved by each Investor Certificateholder of each Series then in existence
prior to the issuance of such new Series.

     Section 5.10 GLOBAL CERTIFICATE; EURO-CERTIFICATE EXCHANGE DATE. If
specified in the related Supplement for any Series, the Investor Certificates
may be initially issued in the form of a single temporary Global Certificate
(the "GLOBAL CERTIFICATE") in bearer form, without interest coupons, in the
denomination of the Initial Certificate Balance and substantially in the form
attached to the related Supplement. Unless otherwise specified in the related
Supplement, the provisions of this SECTION 5.10 shall apply to such Global
Certificate. The Global Certificate will be executed and authenticated by the
Trustee upon the same conditions, in substantially the same manner and with the
same effect as the Definitive Certificates. The Global Certificate may be
exchanged in the manner described in the related Supplement for permanent
Registered and/or Bearer Certificates in definitive form (the "DEFINITIVE
EURO-CERTIFICATES").

     Section 5.11 BOOK-ENTRY CERTIFICATES. Unless otherwise provided in any
related Supplement, the Investor Certificates, upon original issuance, shall be
issued in the form of typewritten Certificates representing the Book-Entry
Certificates, to be delivered to the depository specified in such Supplement
(the "DEPOSITORY") which shall be the Clearing Agency or Foreign Clearing
Agency, as the case may be, by or on behalf of such Series. The Investor
Certificates of each Series shall unless otherwise provided in the related
Supplement initially be

                                       70
<Page>

registered on the Certificate Register in the name of the nominee of the
Clearing Agency or Foreign Clearing Agency, as the case may be. No Certificate
Owner will receive a registered definitive certificate (a "DEFINITIVE
CERTIFICATE") representing such Certificate Owner's interest in the related
Series of Investor Certificates, except as provided in SECTION 5.13 below.
Unless otherwise provided in any related Supplement, unless and until Definitive
Certificates have been issued to Certificate Owners pursuant to SECTION 5.13
below:

          (a)     the provisions of this SECTION 5.11 shall be in full force and
effect with respect to each such Series;

          (b)     the Sellers, the Servicer, the Paying Agent, the Transfer
Agent and Registrar and the Trustee may deal with the Clearing Agency and the
Clearing Agency Participants for all purposes (including the making of
distributions on the Investor Certificates of each such Series) as the
authorized representatives of the Certificate Owners; PROVIDED, HOWEVER, that
the Sellers, the Servicer, the Paying Agent, the Transfer Agent and Registrar
and the Trustee shall treat the Holder thereof as the absolute owner thereof for
all purposes (including the making of distributions on such Registered
Certificate).

          (c)     to the extent that the provisions of this SECTION 5.11
conflict with any other provisions of this Master Trust Agreement, the
provisions of this SECTION 5.11 shall control with respect to each such Series;
and

          (d)     the rights of Certificate Owners of each such Series shall be
exercised only through the Clearing Agency and the applicable Clearing Agency
Participants and shall be limited to those established by law and agreements
between such Certificate Owners and the Clearing Agency and/or the Clearing
Agency Participants. Pursuant to the Depository Agreement applicable to a
Series, unless and until Definitive Certificates of such Series are issued
pursuant to SECTION 5.13 below, the initial Clearing Agency will make book-entry
transfers among the Clearing Agency Participants and receive and transmit
distributions of principal and interest on the Investor Certificates to such
Clearing Agency Participants.

     Section 5.12 NOTICES TO CLEARING AGENCY. Whenever notice or other
communication to the Certificateholders is required under this Master Trust
Agreement, unless and until Definitive Certificates shall have been issued to
Certificate Owners pursuant to SECTION 5.13, then, with respect to Certificate
Owners, the Trustee shall give all such notices and communications specified
herein to be given to Holders of the Investor Certificates to the Clearing
Agency for distribution to Certificate Owners.

     Section 5.13 DEFINITIVE CERTIFICATES. If (a) (i) any Seller advises the
Trustee in writing that the Clearing Agency is no longer willing or able to
discharge properly its responsibilities under the applicable Depository
Agreement, and (ii) the Trustee or such Seller is unable to locate a qualified
successor Clearing Agency, or (b) such Seller, at its option, advises the
Trustee in writing that it elects to terminate the book-entry system through the
Clearing Agency with respect to any Series of Certificates, the Clearing Agency
shall notify all Certificate Owners of such Series, through the applicable
Clearing Agency Participants, of the occurrence of any such event and of the
availability of Definitive Certificates to Certificate Owners of such Series
requesting the same. Upon surrender to the Trustee of the Investor Certificates
representing the

                                       71
<Page>

Book-Entry Certificates of such Series by the applicable Clearing Agency,
accompanied by written registration instructions from the applicable Clearing
Agency for registration, the Trustee shall execute, authenticate and deliver to
the Certificate Owners the Definitive Certificates of such Series in authorized
denominations. Neither the Sellers nor the Trustee shall be liable for any delay
in delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Certificates of such Series, the Trustee shall recognize the Holders of the
Definitive Certificates of such Series as Certificateholders of such Series
hereunder.

     Section 5.14 SUBORDINATION OF SUBORDINATED CERTIFICATES AND SELLERS'
CERTIFICATE.

          (a)     All payments with respect to the Sellers' Certificate and any
Subordinated Certificate (the "SUBORDINATED PAYMENT OBLIGATIONS") shall be
postponed and subordinated to the payment in full of all amounts due under the
Investor Certificates (the "SENIOR PAYMENT OBLIGATIONS"), and no payments or
other distributions whatsoever in respect of any Subordinated Payment
Obligations shall be made, nor shall any Collections or any other Trust Assets
be applied to the purchase or other acquisition or retirement of any
Subordinated Payment Obligations.

          (b)     In the event of any insolvency relating to the Trust, the
Guarantor, any Seller or TMM Multimodal or, after its formation, Newco or
affecting any of their property (whether voluntary or involuntary, partial or
complete, and whether in bankruptcy, insolvency or receivership, or upon an
assignment for the benefit of creditors), or any other marshalling of the assets
and liabilities of the Trust, the Guarantor, any Seller, TMM Multimodal or,
after its formation, Newco or any sale of all or substantially all of the assets
of the Trust, the Guarantor, any Seller, TMM Multimodal or, after its formation,
Newco or otherwise, the Senior Payment Obligations, including all amounts
accruing under the Transaction Documents, whether for interest, fees and costs,
or otherwise, on or after the occurrence of such event, and notwithstanding
that, by operation of Sections 502(b) and 506 of the Bankruptcy Code or other
law governing such proceeding, such amounts may not constitute enforceable
claims against or be payable during or after such proceeding by the entity that
is the subject of such proceeding, shall first be paid in full before the
Subordinated Certificateholder shall be entitled to receive and to retain any
payment or distribution in respect of the Subordinated Payment Obligations and,
in order to implement the foregoing: (i) all payments and distributions of any
kind or character in respect of the Subordinated Payment Obligations to which
each Holder of a Subordinated Certificate or Sellers' Certificate would be
entitled if the Subordinated Payment Obligations were not subordinated, or
subordinated and pledged or assigned pursuant to the Master Trust Agreement,
shall be made directly to the Trustee; (ii) to the extent permitted by
Applicable Law, each Holder of a Subordinated Certificate or Sellers'
Certificate shall promptly file a claim or claims, in the form required in such
proceedings, for the full outstanding amount of the Subordinated Payment
Obligations, and shall cause said claim or claims to be approved and all
payments and other distributions in respect thereof to be made directly to the
Trustee; and (iii) each Holder of a Subordinated Certificate or Sellers'
Certificate hereby irrevocably agrees that the Trustee may, at its sole
discretion, in the name of the undersigned or otherwise, demand, sue for,
collect, receive and receipt for any and all such payments or distributions, and
file, prove and vote or consent in any such proceedings with respect to any and
all claims of each Holder of a

                                       72
<Page>

Subordinated Certificate or Sellers' Certificate relating to the Subordinated
Payment Obligations for the benefit of the Senior Payment Obligations.

          (c)     In the event that any Subordinated Certificateholder or any
Seller receives any payment or other distribution of any kind or character from
any source whatsoever, in respect of any of the Subordinated Payment
Obligations, such payment or other distribution shall be received in trust for
the Trustee and promptly turned over by such Subordinated Certificateholder or
Seller to the Trustee for the benefit of the Senior Payment Obligations and
shall be allocated by the Trustee and distributed by the Paying Agent in the
order of application and distribution set forth in Sections 4.3 and 4.4 of each
of the Series 2001-A Supplement and Series 2002-A Supplement or equivalent
allocation and distribution sections of another Supplement. Each Subordinated
Certificateholder or Seller, as applicable, will mark its books and records so
as clearly to indicate that the Subordinated Payment Obligations are
subordinated in accordance with the terms of the Subordinated Certificate or
Sellers' Certificate, as applicable, and the Master Trust Agreement, and will
cause to be clearly inserted in any certificate, promissory note or other
instrument which at any time evidences any of the Subordinated Payment
Obligations a statement to the effect that the payment thereof is subordinated
in accordance with the terms of such Subordinated Certificate, the Sellers'
Certificate and the Master Trust Agreement. TMM will cause each Subordinated
Certificateholder and each other Seller to execute such further documents or
instruments and take such further action as the Trustee may reasonably from time
to time request or as may otherwise be necessary in order to carry out the
intent of the Subordinated Certificate or Sellers' Certificate.

          (d)     All payments and distributions received by the Trustee in
respect of the Subordinated Payment Obligations, to the extent received in or
converted into cash, may be applied by the Trustee first to the payment of any
and all expenses (including reasonable attorneys' fees and legal expenses) paid
or incurred by the Trustee in enforcing its rights hereunder, or in endeavoring
to collect or realize upon any of the Subordinated Payment Obligations or any
security therefor, and any balance thereof shall, solely as between the
Subordinated Certificateholder and the Trustee, shall be allocated by the
Trustee and distributed by the Paying Agent in the order of application and
distribution set forth in Sections 4.3 and 4.4 of each of the Series 2001-A
Supplement and Series 2002-A Supplement or equivalent allocation and
distribution sections of another Supplement, toward the payment of the Senior
Payment Obligations remaining unpaid; and, notwithstanding any such payments or
distributions received by the Trustee in respect of the Subordinated Payment
Obligations and so applied by the Trustee toward the payment of the Senior
Payment Obligations, the Subordinated Certificate and Sellers' Certificate shall
be subrogated to the then existing rights of the Trustee, if any, in respect of
the Senior Payment Obligations, only at such time as the Senior Payment
Obligations shall have been paid in full.

<Page>

          (a)     TMM is hereby appointed as Servicer on behalf of the Trust
under a collection mandate from the Trust under Chapter I of Title Third of Book
Second of the Mexican Commerce Code. TMM hereby agrees to act as the Servicer
under this Master Trust Agreement. Each Investor Certificateholder, by its
acceptance of its Investor Certificate, consents to TMM acting as Servicer.

          (b)     The Servicer shall have full power and authority, acting alone
or through any party properly designated by it hereunder, to do any and all
things in connection with performing its obligations as Servicer hereunder which
it may deem necessary or desirable. Without limiting the generality of the
foregoing, the Servicer is hereby authorized and empowered (i) to cooperate with
the Trustee in conducting any enforcement proceedings with respect to the
Purchased Receivables and (ii) to make any filings, reports, notices,
applications, registrations with, and to seek any consents or authorizations
from the CNBV, the Securities and Exchange Commission and any state securities
authority on behalf of the Trust as may be necessary or advisable to comply with
any Mexican, U.S. federal or state securities or reporting requirements and
laws. The Trustee shall furnish the Servicer, at TMM's sole cost and expense,
with any documents in its possession which are reasonably requested by any
Seller or the Servicer and are reasonably necessary or appropriate to enable the
Servicer to carry out its servicing and administrative duties hereunder.

          (c)     The Servicer shall be required to pay for its own account the
expenses of performing its obligations as Servicer under this Master Trust
Agreement and shall not be entitled to any payment or reimbursement therefor,
other than any fee payable to the Servicer as specifically set forth and payable
pursuant to the terms of any Supplement. The Servicer's expenses include the
reasonable fees and disbursements of independent public accountants and all
other expenses incurred by the Servicer in connection with its activities
hereunder.

     Section 6.2  REPRESENTATIONS AND WARRANTIES OF THE SERVICER. TMM, as
Servicer, hereby makes the following representations and warranties on and as of
the Document Closing Date, the Initial Closing Date and each subsequent Closing
Date, including the Third Closing Date:

          (a)     ORGANIZATION. The Servicer is a Mexican corporation duly
organized and validly existing under the laws of Mexico and has full corporate
power, authority and legal right to own its properties and conduct its business
as such properties are presently owned and such business is presently conducted,
and to execute, deliver and perform its obligations under this Master Trust
Agreement in all material respects.

          (b)     DUE QUALIFICATION. The Servicer is not required to qualify or
register as a foreign corporation in any state of the United States in order to
act as Servicer as required by this Master Trust Agreement and has obtained all
licenses and approvals and made all filings materially necessary in order to so
act as Servicer as are required under any Requirement of Law. If the Servicer
shall be required by any Requirement of Law to so qualify or register or obtain
such license or approval, then it shall do so unless its failure to do so is not
reasonably likely to result in a Material Adverse Effect.

                                       74
<Page>

          (c)     DUE AUTHORIZATION. The execution, delivery, and performance of
any Transaction Document to which it is a party and the consummation of the
transactions therein by the Servicer have been duly authorized by the Servicer
by all necessary corporate action on the part of the Servicer.

          (d)     BINDING OBLIGATION. Any Transaction Document to which it is a
party constitutes a legal, valid and binding obligation of the Servicer,
enforceable in accordance with its terms, except as such enforceability may be
limited by applicable bankruptcy, CONCURSO MERCANTIL, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
affecting the enforcement of creditors' rights in general, or as such
enforceability may be limited by general principles of equity (whether
considered in a suit at law or in equity).

          (e)     NO CONFLICT. The execution and delivery of any Transaction
Document to which it is a party and the fulfillment of the terms thereof by the
Servicer will not conflict with or result in the breach of any of the material
terms and provisions of, or constitute (with or without notice or lapse of time
or both) a default under any indenture, contract, agreement, mortgage, deed of
trust or other instrument to which the Servicer is a party or by which it or any
of its properties is bound, except for any conflict, breach or default which is
not reasonably likely to result in a material adverse effect on the
Certificateholders or Certificate Owners or the ability of the Servicer to
perform its obligations under any Transaction Document to which it is a party.

          (f)     NO VIOLATION. The execution and delivery of any Transaction
Document to which it is a party by the Servicer, the performance of the
transactions contemplated by any Transaction Document to which it is a party and
the fulfillment of the terms hereof and thereof applicable to the Servicer, will
not conflict with or violate any certificate of incorporation, articles of
association, by-laws, ACTA CONSTITUTIVA, ESTATUTOS SOCIALES, or other
organizational or governing documents of the Servicer or any law, treaty, rule
or regulation, or determination of an arbitrator or Governmental Authority
applicable to or binding upon the Servicer, except for any conflict or violation
which is not reasonably likely to result in a Material Adverse Effect.

          (g)     NO PROCEEDINGS. There are no proceedings or investigations
pending or, to the best knowledge of the Servicer, threatened against the
Servicer, before any court, regulatory body, administrative agency or other
tribunal or governmental instrumentality seeking any determination or ruling
that, in the reasonable judgment of the Servicer, are reasonably likely to
result in a material adverse effect on the Certificateholders or Certificate
Owners or the ability of the Servicer to perform its obligations under any
Transaction Document to which it is a party.

          (h)     ALL CONSENTS REQUIRED. All approvals, authorizations,
consents, orders or other actions of any Person or of any Governmental Authority
or official required in connection with the execution and delivery of any
Transaction Document to which the Servicer is a party, the performance by the
Servicer of the transactions contemplated by any Transaction Document to which
it is a party and the fulfillment of the terms thereof have been obtained except
to the extent the failure to obtain the same is not reasonably likely to result
in a material adverse effect on the Certificateholders or Certificate Owners or
the ability of the Servicer to perform its obligations under any Transaction
Document to which it is a party.

                                       75
<Page>

          (i)     NO IMMUNITY. Under the laws of Mexico neither the Servicer nor
its property has 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).

          (j)     MATERIAL ADVERSE EFFECT. The reasonable likelihood of any act,
event or condition resulting in a "material adverse effect" as that term is used
in this SECTION 6.2, shall be based solely on the facts and circumstances in
existence on the applicable Closing Date.

     Section 6.3  COVENANTS OF THE SERVICER.

          (a)     ADMINISTRATION OF PURCHASED RECEIVABLES. The Servicer shall
manage, service, administer and make collections on the Purchased Receivables
with reasonable care and in accordance with the TMM Credit and Collection
Policies, using that degree of skill and attention that the Servicer would
exercise with respect to the Purchased Receivables if the Servicer were the
owner thereof.

          (b)     COLLECTIONS. The Servicer shall remit promptly to the Trust
any payments on the Purchased Receivables, including without limitation any
Collections, received directly by the Servicer.

          (c)     COOPERATION WITH TRUSTEE. The Servicer shall cooperate with
and assist the Trustee in preparing the Weekly Trustee Report and the Monthly
Trustee Report, including, without limitation, by providing to the Trustee any
information requested by the Trustee relating to such reports.

          (d)     SERVICER REPORT. On each Determination Date, the Servicer
shall provide the Trustee with (i) a compliance certificate indicating the level
of each of the Receivables Coverage Ratio and the Generation Coverage Ratio and
including a list of the Owed Amounts as of such Determination Date (the
"SERVICER REPORT") in substantially the form set forth in EXHIBIT C hereto and
(ii) reports on revenue levels and payments on account of the Purchased
Receivables and such other information, documents, records or reports with
respect to the Purchased Receivables or the conditions of operations, financial
or otherwise, of the Seller, as the Trustee may from time to time reasonably
require in order to protect the interests of the Trustee and the
Certificateholders in connection with this Master Trust Agreement.

          (e)     ANNUAL SERVICER'S CERTIFICATE. On or before March 31 of each
calendar year, beginning with March 31, 2003, the Servicer will deliver to the
Trustee and the Paying Agent (if other than the Trustee) an Officer's
Certificate substantially in the form of EXHIBIT E hereto stating that (a) a
review of the activities of the Servicer during the twelve-month period ending
on December 31 of the previous calendar year, and of its performance under this
Master Trust Agreement, was made under the supervision of the Person signing
such certificate and (b) to the best of such Person's knowledge, based on such
review, the Servicer has fully performed all its obligations under this Master
Trust Agreement throughout such period, or, if there has been a default in the
performance of any such obligation, specifying each such default known to such
officer and the nature and status thereof. A copy of such certificate may be
obtained by any

                                       76
<Page>

Investor Certificateholder by a request in writing to the Trustee addressed to
the Corporate Trust Office.

          (f)     PRESERVATION OF CORPORATE EXISTENCE. Except as permitted under
SECTION 3.3 with respect to TMM only, the Servicer shall preserve and maintain
its corporate existence, rights, franchises and privileges in the jurisdiction
of its incorporation, and qualify and remain qualified in good standing as a
foreign corporation in each jurisdiction where the failure to preserve and
maintain such existence, rights, franchises, privileges and qualifications is
reasonably likely to result in a material adverse effect on the
Certificateholders or Certificate Owners or the ability of the Servicer to
perform its obligations under any Transaction Document to which it is a party.

          (g)     AUDITS. At any time and from time to time during regular
business hours during a Rapid Amortization Period (and upon five (5) Business
Days' written notice if not during a Rapid Amortization Period), the Servicer
shall permit the Trustee, or its agents or representatives (i)(A) to examine and
make copies of and abstracts from all books, records and documents (including,
without limitation, computer tapes and disks) in possession or under the control
of the Servicer relating to the Purchased Receivables, including, without
limitation, the Obligor Agreements, and (B) to visit the offices and properties
of the Servicer for the purpose of examining such materials described in CLAUSE
(i)(A), and to discuss matters relating to the Purchased Receivables or the
performance of its obligations hereunder with any officers of the Servicer or
employees having knowledge of such matters, and (ii) without limiting the
foregoing CLAUSE (i), from time to time on request of the Trustee (given not
more than once in each calendar year so long as no Rapid Amortization Event or
Unmatured Rapid Amortization Event shall have occurred and be continuing),
permit certified public accountants or other auditors acceptable to the Trustee
to conduct, at the Servicer's expense, a review of the Servicer's books and
records with respect to the Purchased Receivables.

          (h)     COMPLIANCE WITH REQUIREMENTS OF LAW. The Servicer shall duly
satisfy all obligations on its part to be fulfilled under any Transaction
Document to which it is a party and will comply in all material respects with
all other Requirements of Law the failure to comply with which is reasonably
likely to result in a material adverse effect on the Certificateholders or
Certificate Owners of any Series or the ability of the Servicer to perform its
obligations under any Transaction Document to which it is a party.

          (i)     MAINTENANCE OF PROPERTIES; INSURANCE. TMM, on behalf of itself
and each of the other Sellers, will cause all properties used in connection with
the Obligor Agreements to be maintained and kept in good condition, repair and
working order, ordinary wear and tear accepted, and shall see the same are
supplied with all necessary equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof as in the
judgment of TMM may be necessary so that business carried on in connection
therewith may be conducted in the ordinary course consistent with TMM's and its
Subsidiaries' custom and practice at all times; PROVIDED, HOWEVER, that nothing
in this Section shall prevent TMM from discontinuing the operation or
maintenance of any such properties which in the reasonable judgment of TMM are
no longer necessary or useful to the conduct of its or any other Seller's
business or the business of TMM's other consolidated Subsidiaries so long as
such

                                       77
<Page>

discontinuance of operations or maintenance shall not have a material adverse
effect on the Purchased Receivables.

     Section 6.4  [Intentionally Omitted].

     Section 6.5  TERMINATION OF THE SERVICER. If a Servicer Default shall have
occurred and be continuing, the Trustee, by notice given to the Servicer, and if
the Servicer is not TMM, to the Sellers' Representative, shall upon the written
directions of the Cumulative Required Investor Certificateholders terminate all
of the rights and powers of the Servicer under this Master Trust Agreement,
including without limitation all rights of such Servicer to receive any
servicing compensation provided for in the applicable Supplement with respect to
the period following such termination. Upon the giving of any such notice under
SECTION 10.5 below, the Trustee shall designate as successor Servicer any Person
(upon the written direction of the Cumulative Required Investor
Certificateholders to succeed such Servicer on the condition that the Trustee
determines that such Person meets sections (a) and (c) of the definition of
"Successor Servicer Criteria" and such Person certifies pursuant to section (b)
of the definition of "Successor Servicer Criteria" that it is legally qualified
to act as the successor Servicer. A Person so designated shall agree to assume
the duties and obligations of such Servicer under the Transaction Documents in
accordance with the terms hereof or thereof or such other terms as may be
acceptable to the Trustee, and upon such assumption all rights, duties and
responsibilities of the Servicer under the Transaction Documents shall vest in
such successor Servicer, and the Trustee is hereby irrevocably and independently
authorized, appointed and empowered to execute and deliver, on behalf of such
Servicer, as attorney-in-fact or otherwise (which appointment as
attorney-in-fact is with full power of substitution and coupled with an
interest), all documents and other instruments (including any notices to
Obligors deemed necessary or advisable by the Trustee), and to do or accomplish
all other acts or things, necessary or appropriate to effect such vesting and
assumption, including, without limitation, directing the Obligors to remit all
payments on or in respect of the Purchased Receivables to an account or address
designated by the Trustee or such successor Servicer and endorsing the name of
such Servicer on checks and other instruments representing Collections with
respect to the Purchased Receivables and enforcing such Purchased Receivables.
Further, in such event, such Servicer shall use its best efforts to effect the
orderly and efficient transfer of the servicing of the Purchased Receivables to
such successor Servicer, and as promptly as practicable, such Servicer shall
provide applicable records to such successor Servicer. In no event shall the
Trustee be obligated to act as a successor Servicer hereunder.

     Notwithstanding the termination of any Person's rights and powers as
Servicer under this Master Trust Agreement, such Person shall remain obligated
to deposit all payments on the Purchased Receivables, including without
limitation all Collections, in the Collection Account promptly upon receipt.

     Section 6.6  ASSUMPTION OF THE OBLIGATIONS OF THE SERVICER. The obligations
or duties of the Servicer hereunder shall not be assignable nor shall any Person
succeed to the obligations of the Servicer hereunder, whether due to a
consolidation of the Servicer with, or a merger into, another Person, or due to
a conveyance or transfer of the Servicer's properties and assets substantially
as an entirety to any Person, or otherwise, except for:

                                       78
<Page>

          (a)     the termination and appointment of a successor Servicer
pursuant to SECTION 6.5 above; or

          (b)     any assignment and assumption of obligations pursuant to
SECTION 6.7 below; or

          (c)     unless, in the case of consolidations, mergers, conveyances or
transfers:

                  (i)    in the event that the Servicer is TMM, the
     consolidation, merger, transfer or conveyance complies with SECTION 3.3
     above and, in the event of a Servicer other than TMM, the entity which is
     the Servicer immediately prior to such consolidation, merger, conveyance or
     transfer is the surviving corporation formed by such consolidation or
     merger, and remains in compliance with every covenant and obligation of the
     Servicer, as applicable hereunder;

                  (ii)   any transfer of the assets of the Servicer either
     directly or indirectly does not have a material adverse effect on the
     ongoing business, condition (financial or otherwise), operations,
     performance, properties or prospects of the Servicer;

                  (iii)  the Enhancement Provider, if any, under each
     outstanding Series has given its consent thereto, which consent shall not
     be unreasonably withheld; and

                  (iv)   the Servicer has delivered to the Trustee an Officer's
     Certificate stating that such consolidation, merger, conveyance or transfer
     complies with this SECTION 6.6 and that all conditions precedent herein
     provided for relating to such transaction have been complied with; or

          (d)     those Services which are purely maritime in nature having to
do with the maintenance, operation, repair, chartering of vessels or
administration of the maritime aspects of the Obligor Agreements.

     Section 6.7  RESIGNATION OF THE SERVICER. The Servicer shall not resign
from the obligations and duties hereby imposed on it except (a) upon
determination that (i) the performance of its duties hereunder is no longer
permissible under applicable law and (ii) there is no reasonable action which
the Servicer could take to make the performance of its duties hereunder
permissible under applicable law or (b) upon the assumption, by an agreement
supplemental hereto, executed and delivered to the Trustee, in form reasonably
satisfactory to the Trustee, of the obligations and duties of the Servicer
hereunder by any of its Affiliates or by any other Person meeting the Successor
Servicer Criteria. Any determination permitting the resignation of the Servicer
shall be evidenced as to clause (a) above by an Opinion of Counsel to such
effect delivered to the Trustee. No resignation shall become effective until a
successor Servicer shall have assumed the responsibilities and obligations of
the Servicer. If, within sixty (60) days after the date of the determination
that the Servicer may no longer act as Servicer under CLAUSE (a) above and a
successor Servicer which is reasonably acceptable to the Sellers and the
Cumulative Required Investor Certificateholders has not been appointed, the
Trustee may petition a court of competent jurisdiction for the appointment of a
successor Servicer hereunder. The Trustee shall give prompt notice to the
Enhancement Provider, if so provided in the related Supplement, upon the
appointment of a successor Servicer.

                                       79

     Section 6.8  LIMITATION ON LIABILITY OF THE SERVICER AND OTHERS. Except as
provided in SECTION 5.6(b) above, neither the Servicer nor any of its directors,
officers, employees or agents shall be under any liability to the Trust, the
Trustee, the Certificateholders or any other Person for any action taken, or for
refraining from the taking of any action, in good faith in its capacity as
Servicer pursuant to this Master Trust Agreement; PROVIDED, HOWEVER, that this
provision shall not protect the Servicer or any such Person against any
liability which would otherwise be imposed by reason of the negligent action of
the Servicer or such Person, the negligent failure to act of the Servicer or
such Person, or the willful misconduct of the Servicer or such Person.

     Section 6.9  INDEMNIFICATION OF THE SERVICER. TMM, on behalf of itself and
each of the other Sellers, shall indemnify and hold harmless the Servicer (if
the Servicer is not TMM), its officers, directors, employees or agents from and
against any Indemnified Loss (whether on account of settlements or otherwise,
and whether or not the Servicer, its officers, directors, employees or agents is
a party to any action or proceeding that gives rise to such Indemnified Loss)
suffered or sustained by reason of any acts, omissions or alleged acts or
omissions arising out of or in connection with the acceptance or administration
of any Transaction Document or the use of proceeds therefrom or the trusts
hereunder and thereunder and its duties hereunder or thereunder; PROVIDED,
HOWEVER, that TMM shall not indemnify the Servicer to the extent of any
Indemnified Losses which are found in a final judgment of a court of competent
jurisdiction to have been caused by gross negligence or willful misconduct by
the Servicer (or the gross negligence or willful misconduct on the part of any
of the Servicer's officers, directors, employees or agents). The obligations of
TMM under this SECTION 6.9 shall survive the termination of the Trust and the
resignation or removal of the Servicer.

     Section 6.10 ACCESS TO CERTAIN DOCUMENTATION AND INFORMATION REGARDING THE
PURCHASED RECEIVABLES. The Trustee shall have access to the books and records of
the Servicer regarding the Purchased Receivables without charge, but only (i)
upon reasonable request and advance notice, (ii) during normal business hours,
(iii) subject to the Servicer's and its designee's normal security and
confidentiality procedures and (iv) at offices designated by the Servicer or its
designee.

     Section 6.11 SERVICER MAY OWN CERTIFICATES. The Servicer and any Affiliate
of the Servicer may become the owner of Certificates but shall not participate
in decisions made or instructions given to the Trustee by the Certificateholders
as a group. The Servicer, if it is not TMM, may otherwise deal with the Sellers
with the same rights as it would have if it were not the Servicer.

     Section 7.1  RAPID AMORTIZATION EVENTS. If any one of the following events
(each a "RAPID AMORTIZATION EVENT") shall occur:

the Sellers under any applicable Supplement); PROVIDED, HOWEVER, in the case of
any payment other than payments of principal and interest on any Distribution
Date, such payment shall not be made for a period of thirty (30) days after the

principal or interest on a Distribution Date, such payment shall not be made for
a period of three (3) Business Days after the date required in this Master Trust

          (b)     (i) TMM (as a Seller, Guarantor, or Sellers' Representative)
or any other Seller shall fail to duly observe or perform in any material
respect any other covenant or agreement of the Sellers in any Transaction
Document, which failure continues unremedied for a period of 30 days (PROVIDED,
THAT, with respect to the covenant set forth in SECTION 3.2(z) hereof the period

discretion;

          (r)     a Change in Control shall have occurred; or

     then, in the case of any event set forth above other than in SECTION 7.1(d)
or SECTION 7.1(g), a Rapid Amortization Commencement Date will be deemed to have

described in such clauses, the Trustee, acting at the direction of the Series
Required Investor Certificateholders of such Series, by written notice to the
Sellers' Representative (the "RAPID AMORTIZATION NOTICE") declares that, as of
the date of such notice, a Rapid Amortization Commencement Date has occurred
with respect to such Series. In the case of any event set forth in SECTION
7.1(d) or (g) above, a Rapid Amortization Commencement Date with respect to all
Series will be deemed to have occurred without any notice or other action on the
part of the Trustee immediately upon the occurrence of such event. In the case
of any event set forth above other than in SECTION 7.1(d), a Rapid Amortization
Commencement Date will be deemed to have been rescinded with respect to a Series
if the Trustee, at the direction of the Series Required Investor
Certificateholders of such Series, by written notice to the Sellers'
Representative, declares that such Rapid Amortization

                                       83
<Page>

Commencement Date has been deemed not to have occurred (such written notice, a
"WAIVER NOTICE"); PROVIDED, HOWEVER, such Waiver Notice shall not affect a Rapid
Amortization Notice given with respect to any other Series. Any Waiver Notice
shall be given within the period commencing on the date on which the Rapid
Amortization Commencement Date has been deemed to have occurred and the date of
the second Distribution Date immediately following such date (the "NOTICE
PERIOD"). During the Notice Period with respect to a Series, all Collections
allocable to such Series will be deposited in the Certificate Account for such
Series until the amount on deposit in the applicable Certificate Account equals
an amount sufficient to pay such Series' Series Percentage of the Trustee Fee
and the Servicing Fee and to pay the Certificate Balance of such Series plus
interest thereon at the Certificate Rate (calculated as during a Rapid
Amortization Period) through the expiration of the Notice Period; PROVIDED,
HOWEVER, that until the expiration of the Notice Period, distributions to the
Certificateholders (other than any Seller or Affiliate thereof or any
Subordinated Certificateholder) will continue to be made on each Distribution
Date. Notwithstanding the foregoing, the Series Required Investor
Certificateholders of a Series may not direct the Trustee to give a Rapid
Amortization Notice with respect to such Series if a Rapid Amortization Event of
the type described at SECTION 7.1(a), (b) OR (c) above arises solely as a result
of a failure to pay or perform or a breach with respect to terms or conditions
of a Supplement relating to another Series.

     Section 7.2  ADDITIONAL RAPID AMORTIZATION EVENTS. A Supplement may specify
events in addition to those specified in SECTION 7.1 above which will constitute
Rapid Amortization Events with respect to the Series to which such Supplement
relates; PROVIDED, HOWEVER, that the procedures for giving a Rapid Amortization
Notice shall not differ from those set forth in the final paragraph of SECTION
7.1 and shall have the consequences specified in SECTION 7.3 below.

     Section 7.3  ADDITIONAL REMEDIES OF CERTIFICATEHOLDERS.

          (a)     If any Rapid Amortization Commencement Date, based on a Rapid
Amortization Event other than those events described in SECTION 7.1(d) above
shall have occurred and shall have not been rescinded, Collections shall be
distributed in accordance with this Master Trust Agreement and the applicable
Supplement.

          (b)     From and after the occurrence of any Rapid Amortization Event,
until the earlier of (i) the date on which all principal and interest on the
Certificates of the Series to which the Rapid Amortization Event applies have
been paid in full and all such Series' Series Percentage of the Trustee's Fees
and Servicer's fees have been paid in full and (ii) the commencement of the
Notice Period, Collections shall continue to be deposited into the Collection
Account and applied as required in this Master Trust Agreement and each
applicable Supplement.

under the TMM Port Option and Put Agreements. Except as provided below in (ii)
and (iii), which (ii) and (iii) paragraphs shall be applied solely with respect
to the Option

                                       85
<Page>

Agreement and Put Option Agreement and not with respect to the TMM Port Option

Series 2001-A Repayment Date, the Trustee will take such actions as contemplated
by the Option Agreement, the Put Option Agreement, the TMM Port Option and Put
Agreements or the Newco Port Option and Put Agreements, as applicable, only as
instructed and directed by the Series 2001-A Series Required Investor
Certificateholders in their sole and absolute discretion and in no event shall
the Trustee or any Series 2001-A Certificateholder have any liability to any
other Certificateholder or Person (including, without limitation, the Series
2002-A Certificateholder) for any action taken by them or at their instruction
(including any enforcement of any remedy or any waiver) in their sole
discretion, or any failure to act or any delay in acting with respect to the
Option Agreement or Put Option Agreement, and such Series 2001-A
Certificateholders shall be authorized to, or to direct the Trustee to, amend,
modify or terminate the Option Agreement or Put Option Agreement in any manner
without liability to any other Certificateholders or Persons, whether or not any
such action, failure to act, modification, amendment or termination adversely
affects the rights or abilities of any Certificateholder of another Series,
including the ability of any Certificateholder of another Series to collect
Proceeds or receive any payment following the Series 2001-A Repayment Date;
PROVIDED, HOWEVER, the foregoing shall not be deemed a waiver by the Series
2002-A Certificateholders of their right to share in any Multimodal Prepayment
Proceeds and Port Shares Prepayment Proceeds actually paid to the Trustee
pursuant to SECTION 4.3 hereof; and; PROVIDED, FURTHER, that the foregoing shall
not be deemed a waiver by TMM Multimodal, TMM or, after its formation, Newco of
any specified rights either of them may have under the terms of the Option
Agreement, Put Option Agreement, the TMM Port Option and Put Agreements or the
Newco Port Option and Put Agreements, as applicable, to approve any such
amendment or modification.

     (ii) The Series 2001-A Series Required Investor Certificateholders shall
provide the Series 2002-A Series Required Investor Certificateholders with at
last three (3) Business Days prior written notice (such notice, a "PROPOSED
INSTRUCTION NOTICE") before instructing the Trustee to deliver an "Exercise

Business Days period (such period, the "CONSULTATION PERIOD"), such Series
2001-A Certificateholders shall consult with the representatives of such Series
2002-A Certificateholders regarding the decision to instruct the Trustee to
deliver the Exercise Notice. In addition, if the Trustee is instructed to
provide an Exercise Notice, such Series 2001-A Certificateholders shall also
instruct the Trustee to provide such Series 2002-A Certificateholders with
copies of all material communications and notifications issued by the Trustee in
the exercise of any remedies taken by the Trustee in respect of the Option
Agreement or Put Agreement. Except for such consultation and notice rights and
except as otherwise provided in paragraph (iii) below, such Series 2001-A
Certificateholders shall have the sole right and discretion to direct and
instruct the Trustee pursuant to paragraph (i) above, and the Series 2002-A
Certificateholders hereby agree not to provide to the Trustee any instruction or
direction contrary in any way to any instruction or direction so provided by
such Series 2001-A Certificateholders to the Trustee. Except as otherwise
provided in paragraph (iii) below, the Trustee acknowledges its obligations to
act solely upon the directions or instructions provided by such Series 2001-A
Certificateholders.

     (iii) At any time following the earlier of (a) the date that the Series
2001-A Series Required Investor Certificateholders give a Proposed Instruction
Notice or (b) if a Proposed Instruction Notice has not been given, the date
which is fifteen (15) Business Days following the

                                       86
<Page>

occurrence and during the continuance of an Exercise Event (as such term in
defined in the Option Agreement), the Series 2002-A Certificateholders shall
have the right, upon advance written notice (the "PURCHASE NOTICE") to the
Series 2001-A Certificateholders, to purchase all (but not less than all) of the
Series 2001-A Certificates at a purchase price equal to the Series 2001-A Full
Repurchase Payment. Such Purchase Notice shall state the date of such purchase
(the "PURCHASE DATE"), which Purchase Date shall be a Business Day not earlier
than two (2) Business Days and nor later than five (5) Business Days after the

purchase shall become irrevocable upon the giving of such a Purchase Notice. The
Series 2002-A Certificateholder that first gives a Purchase Notice is
hereinafter referred to as the "SERIES 2002-A PURCHASER". At all times following
the delivery of the Purchase Notice and through and including the Purchase Date,
the Series 2001-A Certificateholders hereby agree not to instruct the Trustee to
take any actions with respect to the Option Agreement or Put Option Agreement
unless such instruction has been approved by the Series 2002-A Purchaser, which
approval may be withheld by it in its sole discretion; PROVIDED, HOWEVER, that
prior to the Purchase Date, none of the Series 2002-A Certificateholders,
including the Series 2002-A Purchaser, shall give any instruction with respect
to the Option Agreement or Put Option Agreement to the Trustee. At least one (1)
Business Day prior to the Purchase Date, the Series 2002-A Purchaser shall pay
to the Trustee in immediately available funds in Dollars an amount equal to the
Series 2001-A Full Repurchase Payment, which the Trustee shall deposit into the
Series 2001-A Certificate Account. On the Purchase Date, the Paying Agent shall
distribute to the Series 2001-A Certificateholders such Series 2001-A Full
Repurchase Payment amount pro rata in accordance with their respective Series
2001-A Certificate Balances and each Series 2001-A Certificateholder upon the
receipt of the amounts payable to it shall transfer its Series 2001-A
Certificates to the Series 2002-A Purchaser in accordance with the transfer
requirements set forth in Article IX of the Series 2001-A Supplement.

          (e)     EXAMINATION OF DOCUMENTS. The Trustee, upon receipt of any
resolutions, certificates, statements, opinions, reports, documents, orders or
other instruments furnished to the Trustee which are specifically required to be
furnished pursuant to any provision of this Master Trust Agreement, shall
examine them to determine whether they substantially conform to the requirements
of this Master Trust Agreement, but the Trustee will be under no obligation to
verify the contents thereof. The Trustee shall give prompt written notice to any
Enhancement Provider affected thereby and the Certificateholders (or, in the
case of Bearer Certificateholders, notice by publication in the manner described
in the related Supplement) of any material lack of conformity of any such
instrument to the applicable requirements of this Master Trust Agreement
discovered by the Trustee which would entitle such Enhancement Provider or a
specified percentage of the Certificateholders, as the case may be, to take any
action pursuant to this Master Trust Agreement.

          (f)     LIMITATION ON LIABILITY. Subject to SECTION 8.1(a) above, no
provision of this Master Trust Agreement shall be construed to relieve the

of funds or willful misconduct; PROVIDED, HOWEVER, that:

                                       87
<Page>

                  (i)    the Trustee shall not be personally liable for an error
     of judgment made in good faith, unless it shall be proved that the Trustee
     was grossly negligent in ascertaining the pertinent facts or negligent in
     the handling of funds;

                  (ii)   the Trustee shall not be personally liable with respect
     to any action taken, suffered or omitted to be taken by it in good faith in
     accordance with the direction of the Cumulative Required Investor
     Certificateholders, Cumulative Required Investor Certificateholders (Super
     Majority), Series Required Investor Certificateholders or Series Required
     Investor Certificateholders (Super Majority), as applicable, relating to
     the time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any trust or power conferred upon
     the Trustee, under this Master Trust Agreement; and

                  (iii)  The Trustee shall not be required to expend or risk its
     own funds or otherwise incur financial liability in the performance of any
     of its duties hereunder, or in the exercise of any of its rights or powers,
     if there is reasonable ground for believing that the repayment of such
     funds or adequate indemnity against such risk or liability is not
     reasonably assured to it.

          (g)     IMPAIRMENT OF INTERESTS OF THE TRUST. Except for actions
expressly authorized by this Master Trust Agreement, the Trustee shall take no
action reasonably likely to impair the interests of the Trust in the Purchased
Receivables now existing or hereafter created or to impair the value of the
Purchased Receivables now existing or hereafter created.

          (h)     LIMITATION ON POWER. The Trustee shall have no power to vary
the corpus of the Trust including, without limitation, the power to (i) accept
any substitute obligation for the Purchased Receivables, (ii) add any other
investment, obligation or security to the Trust or otherwise encumber the Trust
Assets, or (iii) withdraw from the Trust or sell, transfer, alienate, pledge,
hypothecate or otherwise dispose of the Purchased Receivables, except as
specifically set forth in the Transaction Documents following a Rapid
Amortization Event and upon any optional or mandatory repurchase of the Trust
Assets as specified in the applicable Supplement or any other reassignment or
repurchase of the Trust Assets permitted under any Supplement.

          (i)     PERFORMANCE OF DUTIES. In the event that the Paying Agent or
the Transfer Agent and Registrar shall fail to perform any obligation, duty or
agreement in the manner or on the day required to be performed by the Paying
Agent or the Transfer Agent and Registrar, as the case may be, under this Master
Trust Agreement, the Trustee shall be obligated promptly upon a Responsible
Trustee Officer's obtaining actual knowledge thereof to perform such obligation,
duty or agreement or cause such obligation, duty or agreement to be performed in
the manner so required.

<Page>

          (i)     the rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its rights to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and to each agent, custodian and other Person
employed to act hereunder on behalf of the Trustee and who is acting in
accordance herewith.

          (j)     the Trustee may request that the Sellers and the Servicer
deliver an Officers' Certificate setting forth the names of individuals and/or
titles of officers authorized at such time to take specified actions pursuant to
this Master Trust Agreement, which Officers' Certificate may be signed by any
person authorized to sign an Officers' Certificate, including any person
specified as so authorized in any such certificate previously delivered and not
superseded;

          (k)     beyond the exercise of reasonable care in the custody thereof
and except as provided for in this Master Trust Agreement and any Supplement,
the Trustee shall have no duty as to any Purchased Receivables or any Trust
Assets in its possession or control or in the possession or control of any agent
or bailee or any income thereon or as to preservation of rights against prior
parties or any other rights pertaining thereto. The Trustee shall not be liable
or responsible for any loss or diminution in the value of any Trust Assets, by
reason of the act or omission of any carrier, forwarding agency or other agent
or bailee reasonably selected by the Trustee in good faith; and

          (l)     the Trustee shall not be responsible for the existence,
genuineness or value of any of the Purchased Receivables or other Trust Assets
or for the validity, perfection, priority or enforceability of any lien or
security interest in any of the Trust Assets, whether impaired by operation of
law or by reason of any action or omission to act on its part hereunder, except
to the extent such action or omission constitutes gross negligence, bad faith or
wilful misconduct on the part of the Trustee, for the validity or sufficiency of
the Trust Assets or any agreement or assignment contained therein, for the
validity of the title of the Sellers to the Trust Assets, for the registration
of the Trust Assets with any governmental authority, for insuring the Trust
Assets or for the payment of taxes, charges, assessments or liens upon the Trust
Assets or otherwise as to the maintenance of the Trust Assets, provided,
however, that nothing in this SECTION 8.2(l) shall modify, reduce or have any
effect on the Trustee's express obligations contained in this Master Trust
Agreement or any Supplement.

     Section 8.3  TRUSTEE FEES AND EXPENSES. The Trustee shall be entitled to
receive (from Collections or, in connection with a Receivable Shortfall Payment
or any other payments required to be made by the Sellers or the Sellers'
Representative under any applicable Supplement, from the Sellers' Representative
other than the Proceeds) the Trustee Fees as compensation for all services
rendered by it in the execution of the Trust hereby created and in the exercise
and performance of any of the powers and duties hereunder of the Trustee;
PROVIDED, HOWEVER, that the Trustee shall only be entitled to claim the
applicable Series Percentage of such Trustee Fee from Collections or other
payments allocable to the applicable Series. In addition, the Sellers'
Representative shall pay or reimburse the Trustee (without reimbursement from
the Collection Account, any Series Account or otherwise) upon its request for
all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any of the provisions of this Master Trust Agreement
(including the reasonable fees and expenses of

                                       90
<Page>

its agents, any co-Trustees and counsel) except any such expense, disbursement
or advance as may arise from the gross negligence, negligence in the handling of
funds or willful misconduct by the Trustee. The obligations of the Seller under
this SECTION 8.3 shall survive the termination of the Trust and the resignation
or removal of the Trustee.

     Section 8.4  ELIGIBILITY REQUIREMENTS FOR TRUSTEE; TERMINATION OF QUALIFIED
INSTITUTION.

          (a)     The Trustee hereunder shall at all times be a corporation
organized and doing business under the laws of the United States of America or
any state thereof authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least U.S.$50,000,000 and subject to
supervision or examination by federal or state authority and with a long-term
debt rating of at least BBB by Standard & Poor's. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purpose of
this SECTION 8.4, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. In case at any time the Trustee shall cease to
be eligible in accordance with the provisions of this SECTION 8.4, the Trustee
shall promptly resign in the manner and with the effect specified in SECTION 8.5
below.

          (b)     If the Trustee ceases to be a Qualified Institution, then the
Trustee shall (i) provide the Sellers' Representative, the Servicer and the
Cumulative Required Investor Certificateholders (Super Majority) with prompt
written notice that it is no longer a Qualified Institution and (ii) transfer
the funds deposited in all Series Accounts to another Qualified Institution
designated by the Servicer, and reasonably acceptable to the Cumulative Required
Investor Certificateholders (Super Majority) and (iii) otherwise give such
written notices and execute such written instructions as required by this Master
Trust Agreement, the Control Agreement or the Conversion Agreement, within 10
Business Days of the day on which the Trustee ceased to be a "Qualified
Institution".

     Section 8.5  RESIGNATION OR REMOVAL OF TRUSTEE.

          (a)     The Trustee may at any time resign and be discharged from the
Trust hereby created by giving written notice thereof to the Servicer with a
copy to each Enhancement Provider. In addition, the Trustee may be removed by
the Cumulative Required Investor Certificateholders (Super Majority) if they
deliver written notice to the Trustee to the effect that they have elected to
remove the Trustee for cause and the Servicer (provided that no Rapid
Amortization Event shall have occurred and be continuing) consents to such
removal (which consent shall not be unreasonably withheld or delayed). Upon
receiving such notice of resignation or removal, such Investor
Certificateholders shall promptly appoint a successor trustee, reasonably
acceptable to the Servicer, by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee, subject to the consent of the Enhancement Provider of any
Series (if the Supplement relating to such Series so requires), which consent
shall not be unreasonably withheld. If no successor trustee shall have been so
appointed and have accepted within thirty (30) days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

                                       91
<Page>

          (b)     If at any time the Trustee shall cease to be eligible in
accordance with the provisions of SECTION 8.4 above and shall fail to resign
after written request therefor by the Investor Certificateholders described in
SECTION 8.5(a) above, or if at any time the Trustee shall be legally unable to
act, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee
or of its property shall be appointed, or any public officer shall take charge
or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, then such Investor
Certificateholders may remove the Trustee and promptly appoint a successor
trustee, reasonably acceptable to the Servicer, by written instrument, in
duplicate, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor trustee.

          (c)     Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this SECTION 8.5 shall
not become effective until acceptance of appointment by the successor trustee as
provided in SECTION 8.6 below and any liability of the Trustee arising hereunder
shall survive such appointment of a successor trustee.

          (d)     Prior to its removal or resignation, the Trustee shall give
such written notices and execute such written instructions as required by the
Master Trust Agreement, the Control Agreement or the Conversion Agreement.

     Section 8.6  SUCCESSOR TRUSTEE.

          (a)     Any successor trustee appointed as provided in SECTION 8.5
above shall execute, acknowledge and deliver to the Sellers and to its
predecessor Trustee an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor Trustee shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with the like effect as if originally
named as Trustee herein. The predecessor Trustee, provided all sums then due and
payable to it hereunder have been paid, shall deliver to the successor trustee
all documents and statements held by it hereunder, and the Sellers and the
predecessor Trustee shall execute and deliver such instruments and do such other
things as may reasonably be required for fully and certainly vesting and
confirming in the successor trustee all such rights, powers, duties and
obligations.

          (b)     No successor trustee shall accept appointment as provided in
this SECTION 8.6 unless at the time of such acceptance such successor trustee
shall be eligible under the provisions of SECTION 8.4 above.

          (c)     Upon acceptance of appointment by a successor trustee as
provided in this SECTION 8.6, such successor trustee shall mail notice of such
succession hereunder to all Certificateholders at their addresses as shown in
the Certificate Register. Notice to Bearer Certificateholders shall be given in
the manner provided in the related Supplement.

     Section 8.7  MERGER OR CONSOLIDATION OF TRUSTEE. Any Person into which the
Trustee may be merged or converted or with which it may be consolidated, or any
Person resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any Person succeeding to the corporate trust
business of the Trustee, shall be the successor of the Trustee

                                       92
<Page>

hereunder, PROVIDED that such corporation shall be eligible under the provisions
of SECTION 8.4 above, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding.

     Section 8.8  APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.

          (a)     Notwithstanding any other provisions of this Master Trust
Agreement, at any time, for the purpose of meeting any legal requirements of any
jurisdiction in which any part of the Trust may at the time be located, the
Trustee shall have the power and may execute and deliver all instruments to
appoint one or more Persons to act as a co-trustee or co-trustees, or a separate
trustee or separate trustees, of all or any part of the Trust, and to vest in
such Person or Persons, in such capacity and for the benefit of the
Certificateholders, such title to the trust, or any part thereof, and, subject
to the other provisions of this SECTION 8.8, such powers, duties, obligations,
rights and trusts as the Trustee may consider necessary or desirable. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under SECTION 8.4 above and no notice to
Certificateholders of the appointment of any co-trustee or separate trustee
shall be required under SECTION 8.6 above.

          (b)     Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

                  (i)    all rights, powers, duties and obligations conferred or
     imposed upon the Trustee shall be conferred or imposed upon and exercised
     or performed by the Trustee and such separate trustee or co-trustee jointly
     (it being understood that such separate trustee or co-trustee is not
     authorized to act separately without the Trustee joining in such act),
     except to the extent that under any laws of any jurisdiction in which any
     particular act or acts are to be performed (whether as Trustee hereunder or
     as successor to the Servicer hereunder), the Trustee shall be incompetent
     or unqualified to perform such act or acts, in which event such rights,
     powers, duties and obligations (including the holding of title to the Trust
     or any portion thereof in any such jurisdiction) shall be exercised and
     performed singly by such separate trustee or co-trustee, but solely at the
     direction of the Trustee;

                  (ii)   no trustee hereunder shall be personally liable by
reason of any act or omission of any other trustee hereunder; and

                  (iii)  the Trustee may at any time accept the resignation of
or remove any separate trustee or co-trustee.

          (c)     Any notice, request or other writing given to the Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Master Trust
Agreement and the conditions of this ARTICLE VIII. Each separate trustee and
co-trustee, upon its acceptance of the trusts conferred, shall be vested with
the estates or property specified in its instrument of appointment, either
jointly with the Trustee or separately, as may be provided therein, subject to
all the provisions of this Master Trust Agreement, specifically including every
provision of this Master Trust Agreement relating to the conduct of, affecting
the

                                       93
<Page>

liability of, or affording protection to, the Trustee. Every such instrument
shall be filed with the Trustee and a copy thereof given to the Servicer.

          (d)     Any separate trustee or co-trustee may at any time constitute
the Trustee its agent or attorney-in-fact with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Master Trust Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

     Section 8.9  TAX RETURNS. In the event the Trust shall be required to file
tax returns, the Servicer shall prepare or cause to be prepared any tax returns
required to be filed by the Trust and shall remit such returns to the Trustee
for a signature. The Trustee shall deliver the signed tax returns to the
Servicer within five (5) Business Days after its receipt thereof, but the
Trustee shall have no obligation to confirm the contents of the tax returns. The
Servicer shall prepare or shall cause to be prepared all tax information
required by law to be distributed to Certificateholders and shall deliver such
information to the Trustee at least five (5) days prior to the date it is
required by law to be distributed to Certificateholders. The Trustee, upon
request, will furnish the Servicer with all such information known to the
Trustee as may be reasonably required in connection with the preparation of all
tax returns of the Trust and shall, upon request, execute such returns. In no
event shall the Trustee be liable for any liabilities, costs or expenses of the
Trust, the Investor Certificateholders or the Certificate Owners arising under
any tax law, including without limitation U.S. federal, state, local or foreign
income or excise taxes or any other tax imposed on or measured by income (or any
interest or penalty with respect thereto or arising from a failure to comply
therewith).

     Section 8.10 TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF CERTIFICATES.
All rights of action and claims under this Master Trust Agreement or any Series
of Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee. Any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Certificateholders of any Series in respect of which such
judgment has been obtained.

     Section 8.11 SUITS FOR ENFORCEMENT. If the Servicer or any Seller (for 30
days after written notice of such failure from the Trustee) fails to take any
action it is required to take pursuant to this Master Trust AGREEMENT, the
Trustee, in its discretion may proceed to protect and enforce its rights and the
rights of the Certificateholders of any Series under this Master Trust Agreement
by a suit, action or proceeding in equity or at law or otherwise, whether for
the specific performance of any covenant or agreement contained in this Master
Trust Agreement or in aid of the execution of any power granted in this Master
Trust Agreement or for the enforcement of any other legal, equitable or other
remedy as the Trustee, being advised by counsel, shall deem most effectual to
protect and enforce any of the rights of the Trustee or the Certificateholders
of any Series.

     Section 8.12 RIGHTS OF CERTIFICATEHOLDERS TO DIRECT TRUSTEE. Subject to
SECTIONS 8.1(d), (f) and (g) and SECTION 8.2(c) above, the Cumulative Required
Investor Certificateholders, Cumulative Required Investor Certificateholders
(Super Majority), Series Required Investor Certificateholders and Series
Required Investor Certificateholders (Super Majority), as applicable, shall have
the right to direct the time, method, and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred
on the Trustee; PROVIDED, HOWEVER, that, subject to SECTION 8.1 above, the
Trustee shall have the right to decline to follow any such direction if the
Trustee being advised by counsel determines that the action so directed may not
lawfully be taken, or if the Trustee in good faith shall, by a Responsible
Trustee Officer or Responsible Trustee Officers, determine that the proceedings
so directed would be illegal or involve it in personal liability; and PROVIDED
FURTHER that nothing in this Master Trust Agreement shall impair the right of
the Trustee to take any action deemed proper by the Trustee and which is not
inconsistent with such direction of such Holders of Investor Certificates.

     Notwithstanding any provision in this Master Trust Agreement, if Investor
Certificates are held by a Seller, or any of its Affiliates, such Persons shall
not be permitted to participate in any decisions made by, or instructions given
to, the Trustee by the Investor Certificateholders.

     Section 8.13 REPRESENTATIONS AND WARRANTIES OF TRUSTEE. The Trustee
represents and warrants, as of the Document Closing Date and (unless otherwise
specified in the applicable Supplement) as of the Initial Closing Date and each
subsequent Closing Date, including the Third Closing Date, that:

          (a)     it is a New York banking corporation organized, existing and
in good standing under the laws of the State of New York and its principal
office and place of business is not located in Mexico;

          (b)     it has full power and authority to execute, deliver and
perform this Master Trust Agreement and each Supplement, and has taken all
necessary action to authorize the execution, delivery and performance by it of
this Master Trust Agreement and each Supplement; and

          (c)     this Master Trust Agreement and each Supplement have been duly
executed and delivered by it.

     Section 8.14 MAINTENANCE OF OFFICE OR AGENCY. Each of the Trustee, the
Paying Agent and the Transfer Agent and Registrar will maintain at its expense
in the Borough of Manhattan, The City of New York (or London in the case of
Bearer Certificates), an office or offices or agency or agencies where notices
and demands to or upon the Trustee, the Paying Agent or the Transfer Agent and
Registrar in respect of the Certificates and this Master Trust Agreement may be
served. Each of the Trustee, the Paying Agent and the Transfer Agent and
Registrar initially appoints the Corporate Trust Office as its office for such
purposes in New York. The Trustee, the Paying Agent or the Transfer Agent and
Registrar, as applicable, will give prompt written notice to the Servicer, each
Enhancement Provider and to Certificateholders (in the case of Bearer
Certificates, in the manner provided in the related Supplement) of any change in
the location of the Certificate Register or any such office or agency.

                                       95
<Page>

     Section 8.15 TRUSTEE MAY OWN CERTIFICATES. The Trustee or any Affiliate may
in its individual capacity, as well as in a fiduciary capacity, become the owner
of Certificates, and the Trustee or any Affiliate may otherwise extend credit to
a Seller, but the Trustee (in its capacity as the owner of any Certificate)
shall not participate in decisions made or instructions given to the Trustee by
the Certificateholders as a group. The Trustee may otherwise deal with any
Seller and the Servicer with the same rights as it would have if it were not the
Trustee.

     Section 8.16 INDEMNIFICATION OF TRUSTEE. TMM, on behalf of itself and each
of the other Sellers, shall indemnify and hold harmless the Trustee, each Paying
Agent, each Transfer Agent and Registrar and their respective officers,
directors, employees or agents (each, a "TRUSTEE INDEMNIFIED PARTY") from and
against any Indemnified Loss (whether on account of settlements or otherwise,
and whether or not the relevant Trustee Indemnified Party is a party to any
action or proceeding that gives rise to Indemnified Losses) suffered or
sustained by reason of any acts, omissions or alleged acts or omissions arising
out of or in connection with the acceptance or administration of any Transaction
Document or the use of proceeds therefrom or the trusts hereunder and thereunder
and its duties hereunder or thereunder, including in the case of the Trustee,
Indemnified Losses suffered or sustained (i) while performing any duties or
obligations of the Paying Agent or Transfer Agent and Registrar pursuant to
SECTION 8.1(h) above or (ii) with respect to the signing of tax returns pursuant
to SECTION 8.9 above; PROVIDED, HOWEVER, that TMM shall not indemnify any
Trustee Indemnified Party to the extent of any Indemnified Losses which are
found in a final judgment of a court of competent jurisdiction to have been
caused by gross negligence or willful misconduct by such Trustee Indemnified
Party. The obligations of the Sellers under this SECTION 8.16 are full recourse
obligations and shall survive the termination of the Trust and the resignation
or removal of the Trustee.

                                   ARTICLE IX

                                   TERMINATION

     Section 9.1  TERMINATION OF TRUST. The respective obligations and
responsibilities of each Seller, the Servicer, the Paying Agent and the Trustee
created hereby (other than the obligation of the Paying Agent to make payments
to Certificateholders as hereafter set forth) shall terminate, except with
respect to the duties described in SECTION 3.4, SECTION 5.6, SECTION 6.9,
SECTION 8.1, SECTION 8.2, SECTION 8.16, and SECTION 9.3(b), on the Trust
Termination Date.

     Section 9.2  MANDATORY REPURCHASE AND FINAL TERMINATION OF INVESTOR
CERTIFICATES OF ANY SERIES. Provisions relating to the mandatory repurchase of
any Series of Investor Certificates, if required with respect to any Series,
shall be set forth in the related Supplement for such Series.

     Section 9.3  FINAL PAYMENT WITH RESPECT TO ANY SERIES.

          (a)     Written notice of any termination, specifying the Distribution
Date upon which the Investor Certificateholders of any Series may surrender
their Certificates for payment of the final distribution with respect to such
Series and cancellation, shall be given (subject to at least five (5) Business
Days prior notice from the Servicer to the Trustee) by the Trustee to Investor
Certificateholders of such Series (and the Enhancement Provider if so provided
in the

                                       96
<Page>

related Supplement), mailed (or in the case of Bearer Certificates, published in
the manner specified in the related Supplement) not later than the Determination
Date preceding the date of such final distribution (or in the manner provided by
the Supplement relating to such Series) specifying (i) the Distribution Date
(which shall be the first Distribution Date after the date on which the deposit
is made) upon which final payment of such Investor Certificates will be made
upon presentation and surrender of such Investor Certificates at the office or
offices therein designated (which, in the case of Bearer Certificates, shall be
outside the United States), (ii) the amount of any such final payment and (iii)
that the Record Date otherwise applicable to such Distribution Date is not
applicable, payments being made to the Certificateholders on such Distribution
Date only upon presentation and surrender of the Investor Certificates at the
office or offices therein specified. The Servicer's notice to the Trustee in
accordance with the preceding sentence shall be accompanied by an Officer's
Certificate setting forth the information specified in ARTICLE V of the
applicable Supplement covering the period during the then current calendar year
through the date of such notice and setting forth the date of such final
distribution. Payments shall be made by the Paying Agent to the Investor
Certificateholders in the same manner as provided in the applicable Supplement
for other distributions. The Trustee shall give such notice to the Transfer
Agent and Registrar and the Paying Agent at the time such notice is given to
such Investor Certificateholders.

          (b)     Notwithstanding the termination of the Trust pursuant to
SECTION 9.2 above or the occurrence of the Series Termination Date with respect
to any Series, all funds then on deposit in the Collection Account, Sweep
Account, Peso Denominated Account or any Series Account shall continue to be
held in trust for the benefit of the Certificateholders of the related Series,
and the Paying Agent shall pay such funds to the Certificateholders of the
related Series upon surrender of their Certificates (which surrenders and
payments, in the case of Bearer Certificates, shall be made only outside the
United States). In the event that all of the Investor Certificateholders of any
Series shall not surrender their Certificates for cancellation within six months
after the date specified in the notice described in SECTION 9.3(a) above, the
Trustee shall give a second written notice (in the case of Bearer Certificates,
publication notice) to the remaining Investor Certificateholders of such Series
upon receipt of the appropriate records from the Transfer Agent and Registrar to
surrender their Certificates for cancellation and receive the final distribution
with respect thereto. If within one and one-half years after the second notice
with respect to a Series, all the Investor Certificates of such Series shall not
have been surrendered for cancellation, the Trustee may take appropriate steps,
or may appoint an agent to take appropriate steps, to contact the remaining
Investor Certificateholders of such Series concerning surrender of their
Certificates, and the cost thereof shall be paid out of the funds in the
Collection Account or any Series Account held for the benefit of such Investor
Certificateholders. The Paying Agent shall pay to the Sellers' Representative
upon request any monies held by them for the payment of the principal or
interest which remains unclaimed for two (2) years. After payment to the
Sellers' Representative, Investor Certificateholders entitled to the money must
look solely to the Sellers for payment as general creditors unless an applicable
abandoned property law designates another Person.

          (c)     All Certificates surrendered for payment of the final
distribution with respect to such Certificates and cancellation shall be
canceled by the Transfer Agent and Registrar and be disposed of in a manner
satisfactory to the Trustee and the Seller.

     Section 9.4  SELLERS' TERMINATION RIGHTS. Upon the termination of the Trust
pursuant to SECTIONS 9.1 and 9.3(b) above and the surrender of the Sellers'
Certificate, the Subordinated Certificate and all Investor Certificates of all
outstanding Series, the Trustee shall transfer to the Sellers' Representative
for the benefit of the Holder of the Sellers' Certificate (without recourse,
representation or warranty) all right, title and interest of the Trust in the
Purchased Receivables, whether then existing or thereafter created, all monies
due or to become due with respect thereto and all proceeds thereof except for
amounts held by the Trustee pursuant to SECTION 9.3(b) above. The Trustee shall
execute and deliver such instruments of transfer and assignment, on behalf of
the Trust, in each case without recourse, as shall be reasonably requested by
the Sellers to vest in the Sellers all right, title and interest which the Trust
had in the Purchased Receivables.

                            MISCELLANEOUS PROVISIONS

     Section 10.1 AMENDMENT.

          (a)     (i)    Any Transaction Document may be amended from time to
time by the Servicer, the Sellers and the Trustee, without the consent of any
Holder of any outstanding Certificate, to cure any ambiguity, to correct a
defect or to correct or supplement any provisions herein which may be
inconsistent with any other provisions herein or which may be required due to
any change in applicable law, to add any other provisions with respect to
matters or questions arising under this Master Trust Agreement or any Supplement
which shall not be inconsistent with the provisions of this Master Trust
Agreement or any Supplement; PROVIDED, HOWEVER, that such action shall not
adversely affect in any material respect the interests of any Investor
Certificateholder or violate or conflict with any other Master Trust Agreement
Override Section. The Trustee shall be entitled to receive an Officers'
Certificate and/or an Opinion of Counsel on these matters, prior to executing an
amendment, and the Trustee shall be fully protected in relying thereon. The
Trustee may, but shall not be obligated to, enter into any such amendment which
affects the Trustee's rights, duties or immunities under this Master Trust
Agreement or otherwise.

                  (ii)   This Master Trust Agreement and any Supplement may be
     amended from time to time by the Servicer, the Sellers and the Trustee,
     without Certificateholder consent, to provide that Bearer Certificates
     issued with respect to any Series may be registrable as to principal, to
     change or eliminate any restrictions on the payment of principal of or any
     interest on such Bearer Certificates, to permit such Bearer Certificates to
     be issued in exchange for Registered Certificates or Bearer Certificates of
     other authorized denominations or to permit the issuance of uncertificated
     certificates, subject to certain conditions that may be required at such
     time by the Trustee.

          (b)     Any Transaction Document may also be amended from time to time
by the Servicer, the Sellers and the Trustee with the consent of the Series
Required Investor Certificateholders of each outstanding Series adversely
affected by such amendment and also so long as the Series 2001-A Certificates
are outstanding with the consent of the Series 2001-A Series Required Investor
Certificateholders (Super Majority), which consent may be withheld in the sole
and absolute discretion of the Series 2001-A Certificateholders, if such
amendment

                                       98
<Page>

would cause any Supplement other than the Series 2001-A Supplement to provide
for (1) an earlier Expected Final Distribution Date or other maturity, (2) a
greater level of amortization, (3) any additional or more restrictive covenants
or Rapid Amortization Events, (4) additional optional or obligatory repurchase
rights other than those set forth in the Series 2002-A Supplement in the form
set forth in EXHIBIT P hereto or (5) increase the Certificate Balance of any
other Series (and, to the extent provided in any Supplement, with the consent of
the related Enhancement Provider, which consent shall not be unreasonably
withheld) for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of this Master Trust Agreement or any
Supplement or modifying in any manner the rights of Certificateholders of any
Series then issued and outstanding; PROVIDED, HOWEVER, that the right of any
Enhancement Provider to consent pursuant to any Supplement to any such amendment
shall be limited to matters involving (i) the provisions of this Master Trust
Agreement which affect such Enhancement Provider, (ii) the provisions of the
related Supplement, and (iii) the rights of Certificateholders of the related
Series). Notwithstanding the foregoing, (I) no such amendment shall be permitted
and no such amendment shall (x) reduce in any manner the amount of, or delay the
timing of, distributions which are required to be made on any Investor
Certificate of such Series, (y) change the definition of or the manner of
calculating the Series Percentage or Certificate Balance of such Series or (z)
reduce the percentage of the Certificate Balance required to consent to any such
amendment, without, in each case, the consent of each Investor Certificateholder
of each Series adversely affected thereby. In addition to and without limitation
of the foregoing, no amendment or waiver of any restriction or prohibition
(including any amendment or waiver of a definition related to or used with
respect to such restriction or prohibition) on payments to any Series prior to
the repayment in full of the Series 2001-A Certificateholders shall be effective
without the consent of the Series 2001-A Series Required Investor
Certificateholders (Super Majority) which consent may be withheld in the sole
and absolute discretion of the Series 2001-A Certificateholders.

          (c)     In connection with any amendment to any Transaction Document
effected under SECTION 10.1(b) above, the Trustee shall be entitled to receive
an Opinion of Counsel for the Seller and Servicer covering such matters as the
Trustee may reasonably request.

          (d)     Promptly after the execution of any amendment to any
Transaction Document, the Trustee shall furnish such amendment to any related
Enhancement Provider.

          (e)     Promptly after execution of any amendment to any Transaction
Document, the Trustee shall furnish written notice of the substance of each
amendment to the Investor Certificateholders of each Series (or, with respect to
an amendment of a Supplement, to the Investor Certificateholders of the
applicable Series). The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Investor Certificateholders shall be
subject to such reasonable requirements as the Trustee may prescribe.

     Section 10.2 PROTECTION OF RIGHT, TITLE AND INTEREST TO TRUST.

          (a)     Each Seller shall deliver to the Trustee file-stamped copies
of, or filing receipts for, any financing statement recorded, registered or
filed as provided in SECTION 2.7 above, as soon as available following such
recording, registration or filing.

<Page>

          (b)     Within 30 days after any Seller makes any change in its name,
identity or corporate structure which would make any financing statement or
continuation statement filed in accordance with SECTION 10.2(a) above materially
misleading within the meaning of the UCC, such Seller shall give the Trustee
written notice of any such change and shall file such financing statements or
amendments as may be necessary to continue the perfection of the Trust's
security interest in the Purchased Receivables and the proceeds thereof.

          (c)     Each Seller and the Servicer will give the Trustee prompt
written notice of any relocation of any office from which it services Purchased
Receivables or keeps records concerning the Purchased Receivables (including the
establishment of any office from which it services the Purchased Receivables or
keeps records concerning the Purchased Receivables) or of its principal
executive office and whether, as a result of such relocation, the applicable
provisions of the UCC would require the filing of any amendment of any
previously filed financing or continuation statement or of any new financing
statement and shall file such financing statements or amendments as may be
necessary to continue the perfection of the Trust's security interest in the
Purchased Receivables and the proceeds thereof.

     Section 10.3 LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.

          (a)     The death or incapacity of any Certificateholder shall not
operate to terminate this Master Trust Agreement or the Trust, nor shall such
death or incapacity entitle such Certificateholder's legal representatives or
heirs to claim an accounting or to take any action or commence any proceeding in
any court for a partition or winding up of the Trust, nor otherwise affect the
rights, obligations and liabilities of the parties hereto or any of them.

          (b)     No Certificateholder shall have any right to vote (except with
respect to the Investor Certificateholders as provided in SECTION 10.1 above) or
in any manner otherwise control the operation and management of the Trust, or
the obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Certificates, be construed so as to constitute the
Certificateholders from time to time as partners or members of an association;
nor shall any Certificateholder be under any liability to any third Person by
reason of any action taken by the parties to this Master Trust Agreement
pursuant to any provision hereof.

          (c)     No Certificateholder shall have any right by virtue of any
provisions of this Master Trust Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Master
Trust Agreement, unless an Affected Certificateholder or Series shall have made
written request upon the Trustee to institute such action, suit or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee, for sixty (60) days after its
receipt of such notice, request and offer of indemnity, shall have neglected or
refused to institute any such action, suit or proceeding; it being understood
and intended, and being expressly covenanted by each Certificateholder with
every other Certificateholder and the Trustee, that no one or more
Certificateholders shall have the right in any manner whatever by virtue or by
availing itself or themselves of any provisions of this Master Trust Agreement
to affect, disturb or prejudice the rights of the Certificateholders of any
other of the Certificates, or to obtain or seek to obtain priority over or
preference to any other such Certificateholder, or to enforce any right under
this Master Trust Agreement, except

common benefit of all Certificateholders. For the protection and enforcement of

Certificateholders with respect to any cause of action to enforce either SECTION
8.1(d) hereof or Section 3.1 or Section 7.1(a) of the Series 2001-A Supplement,
or (prior to the Series 2001-A Repayment Date) the prohibition on payment at
Section 3.1(a) of the Series 2002-A Supplement or (y) solely the Series 2002-A
Series Required Investor Certificateholders with respect to any cause of action
to enforce either Section 3.1(b) or (following the Series 2001-A Repayment Date)
Section 3.1(a) of the Series 2002-A Supplement.
