FACTORS AFFECTING FORWARD LOOKING STATEMENTS

The Private Securities Litigation Reform Act of 1995 provides for a safe harbor for forward-looking statements. This annual report of Pemex Finance on
Form 20-F contains words, such as believe, plan, expect and anticipate and similar expressions that constitute forward-looking statements, which reflect Pemex Finances views about future events
and financial performance. Specifically, certain statements under the caption Item 4. Information on the CompanyDescription of Business relating to the operation and performance of Pemex Finance, P.M.I. Comercio Internacional,
S.A. de C.V., which we call PMI, and PEP and under the caption Item 5. Operating and Financial Review and ProspectsManagements Discussion and Analysis of Financial Condition and Results of Operations are
forward-looking statements.

These forward-looking statements are subject to certain risks and uncertainties, including, but not limited
to, changes in import controls or import duties, levies or taxes in international markets, and changes in prices or demand for crude oil in international markets as a result of competitive actions or economic factors. These forward-looking
statements are also subject to the risks of performance by third parties in accordance with contractual terms and specifications. Although we believe that the expectations reflected by these forward-looking statements are reasonable based on
information currently available to us, we cannot assure that such expectations will prove to have been correct. Accordingly, you should not place undue reliance on these forward-looking statements. In any event, these statements speak only as of
their dates, and we undertake no obligation to update or revise any of them, whether as a result of new information, future events or otherwise.

The annual reports on Form 20-F of Petróleos Mexicanos for the fiscal years ended December 31, 2004 and December 31, 2005, incorporated herein by reference, as of the date of their respective filings, also contain or may contain
forward looking statements. For a discussion of the factors affecting the forward looking statements contained therein, see those annual reports.

CURRENCY OF PRESENTATION

References in this annual report to U.S. dollars, U.S.$,
dollars or $ are to the lawful currency of the United States. References in this annual report to pesos or Ps. are to the lawful currency of Mexico which, effective January 1, 1993, replaced
Mexicos former currency (also called the peso) at the rate of one peso to one thousand old pesos. During the transition period from January 1, 1993 through December 31, 1995, the new currency was officially referred to as
the nuevo peso (the new peso) and since January 1, 1996, has been officially referred to as the peso. All amounts set forth in this annual report in Mexican currency are stated in pesos.

This annual report contains translations of certain peso amounts into U.S. dollars at specified rates solely for the sake of convenience. These
translations should not be construed as representations that the peso amounts actually represent such U.S. dollar amounts or could be converted into U.S. dollars at the rate indicated. Unless otherwise indicated, such U.S. dollar amounts have been
translated from pesos at an exchange rate of Ps. 10.7777 to U.S.$1.00, which is the exchange rate that the Ministry of Finance and Public Credit gave PEMEX on December 31, 2005. On June 27, 2006, the noon buying rate for cable transfers in
New York reported by the Federal Reserve Bank of New York was Ps.11.418.

SELECTED FINANCIAL DATA

derived from our previously published audited financial statements not included in this document. The financial statements have been audited by PricewaterhouseCoopers, S.C. independent registered public accounting firm. Our financial statements are
prepared in accordance with the international financial reporting standards, otherwise referred to as IFRS, promulgated by the International Accounting Standards Board. Beginning January 1, 2004, we have changed our financial

financial data set forth below) for the years ended December 31, 2001, 2002 and 2003, in order to present our balance sheet for each of these years on the same basis as the results for the years ended December 31, 2004 and 2005.

RISK FACTORS

We are subject to various changing economic and social conditions, including in the petroleum industry, as described below. You should consider carefully the following factors as well as the other information in
this annual report.

Risks Related to Payments on the Notes

Our ability to make payments on the Notes depends on PEMEXs generation of sufficient eligible receivables.

Generally, our business consists of using the proceeds of the debt we issue to purchase accounts receivable which have been generated or will be generated in the future through the sale of crude oil to the current designated customers of
PMI. PMI purchases the crude oil that it sells to these designated customers from PEP, Petróleos Mexicanos exploration and production affiliate. We make payments on our indebtedness, including the notes that we have further specified
herein that we have issued under a senior indenture dated as of December 1, 1998 (which we call the Notes), from the money that certain designated customers pay into a collection account on eligible accounts receivable for crude
oil. We do not have a direct commercial relationship with these designated customers, and we do not produce, transport or sell crude oil. Accordingly, because we do not generate the eligible receivables ourselves, our ability to make payments on the
Notes depends on the generation of eligible receivables by PMI, including both current eligible receivables and eligible receivables that will be generated in the future. We rely on Petróleos Mexicanos, operating through PMI and PEP, to sell
enough crude oil to the designated customers over time to generate sufficient eligible receivables. We have no control over Petróleos Mexicanos, PEP or PMI.

Petróleos Mexicanos, PEP and PMIs ability to generate enough eligible receivables to allow us to make timely payments on the Notes depends on two factors:



| |  |  | whether the designated customers buy enough of PEMEXs crude oil; and
| | - |  | ---------------------------------------------------------------------



| |  |  | whether PEP can maintain sufficient production levels.
| | - |  | ------------------------------------------------------

1. The designated customers may reduce the amount of crude oil they purchase. The level of demand for PEMEXs crude oil is directly related to the designated customers continuing need for and ability to purchase crude oil
from PMI. However, a designated customers demand for PEMEXs crude oil could diminish for a variety of reasons, including:



| |  |  | changes in the market for that designated customers products,
| | - |  | --------------------------------------------------------------



| |  |  | a decision to purchase crude oil from an alternate source, or
| | - |  | -------------------------------------------------------------



| |  |  | a deterioration in the customers business or financial condition.
| | - |  | ------------------------------------------------------------------

Reduction in designated customer demand could materially limit Petróleos Mexicanos, PEP and PMIs ability to generate eligible receivables.

Similarly, PMI may materially change the terms under which it sells its crude oil to any designated customer. These changes may make it more difficult
for that designated customer to purchase crude oil from PMI. We purchase receivables that have already been generated by PMI, as well as future receivables that PMI will generate. To the extent that the time between the sale and generation of future
receivables increases, these risks will be borne for a longer period. See Item 5. Operating and Financial Review and ProspectsManagements Discussion and Analysis of Financial Condition and Results of OperationsLiquidity
and Capital Resources. We have no control over the designated customers or PMI in situations like these. See Risks Related to PEMEX, PEP and PMICrude oil prices are volatile, and low oil prices negatively affect PEMEXs
income. For a discussion of PEMEXs customers, see Item 4. Information on the CompanyDescription of BusinessPEMEXs Customers and Receivables.

2. PEP may not produce sufficient crude oil to permit the creation of enough eligible receivables.
The ability to generate eligible receivables is also dependent on PEPs continued sale of crude oil through PMI. PEP has agreed not to export crude oil to designated customers other than through PMI. However, PEP has no contractual obligation
to continue to produce and sell crude oil generally. Further, in order to maintain sufficiently high production levels, PEP may have to find additional oil reserves as the existing reserves become depleted. PEP may also need to invest in new
production facilities as the existing facilities become obsolete. We have no control over PEP and cannot guarantee that PEP will be able to find additional reserves or invest in new facilities. See Risks Related to PEMEX, PEP and
PMI.

If collections on purchased receivables are held in the retention account, cash flow available to PEP could be reduced, which could hurt
PEPs ability to produce oil and PMIs ability to generate eligible receivables.

In some circumstances, such as when an
event of default occurs, all or a portion of collections on purchased receivables paid into the collection account will be transferred to a retention account. It is possible that the transfer of funds to the retention account could significantly
reduce our purchases of eligible receivables, which would in turn reduce PEPs operating cash flow. Any reduction in cash flow available to PEP to fund its operations on a day to day basis could adversely affect its ability to produce oil and,
in turn, the level of receivables generated by PMI.

For an explanation of the circumstances in which collections will be paid into the
retention account, see Item 4. Information on the CompanyDescription of Principal AgreementsThe Fiscal Agency AgreementEvents of Default and Funding and Administration of Retention Account.

If PMI fails to generate eligible receivables we have already purchased, we have no recourse to PMI or PMI Services.

Most of the eligible receivables we have purchased and will purchase will be generated at some point in the future. We cannot guarantee that current
market conditions will continue to prevail. Since we have no recourse to PEP, PMI or P.M.I. Services B.V., which we call PMI Services, except in limited circumstances, we alone bear the risk that PMI will not be able to generate the
future eligible receivables for which we have already paid.

If a designated customer fails to honor its payment obligations, we have no recourse to
PMI or PMI Services.

Except in limited circumstances, PMI and PMI Services have no obligation to refund any of our payments for
eligible receivables. This includes payments we have made from the approximately U.S.$ 2.5 billion of proceeds from our indebtedness as of December 31, 2005. Without recourse to PMI, PMI Services or any other entity, we alone bear the risk of a
designated customer failing to honor its payment obligations with respect to any current and future eligible receivables purchased from PMI.

There are only two limited situations in which we may rescind our purchase of eligible receivables and claim repayment of the purchase price from PMI. We may rescind our purchase if:



| |  |  | PMI sells us a receivable that fails to meet the quality standards specified in the receivables purchase agreement; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | PMI does not comply with covenants in the receivables purchase agreement designed to ensure the continuity of its operations and its ability to sell eligible receivables on an
on-going basis.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These limited circumstances do not include the failure of a designated customer to fulfill its payment
obligations. See Item 4. Information on the CompanyDescription of Principal AgreementsThe Receivables Purchase AgreementSubstitution and Repurchase of Receivables. Therefore, once PMI has generated a purchased
receivable, PMI will have satisfied its obligation to deliver that receivable, regardless of whether that customer ultimately pays.

##### Table of Contents

In order to make payments on the Notes, we rely on the designated customers to make timely payments on the
purchased receivables into the collection account.

If one or more designated customers suffer significant negative changes in their
business or financial condition that make it difficult or impossible for them to make payments on the purchased receivables, it will impair our ability to make payments on the Notes. The magnitude of this negative effect will depend primarily on the
amounts these designated customers owe with respect to purchased receivables.

Neither we nor PMI limits the percentage of sales of crude
oil which is sold to particular customers. Similarly, neither we nor PMI places any limit on the amount of any receivables payable by any designated customers purchased receivables or the amount of purchased receivables of P.M.I.
Norteamérica S.A. de C.V., which is an affiliate of PEMEX.

The designated customers do not buy crude oil at set intervals.
Accordingly, we cannot guarantee that any particular pattern of payments into the collection account will occur. The non-payment by even one designated customer may have a substantial impact on the flow of collections into the collection account.

A court may not treat our purchase of eligible receivables as a sale or may contest our purchase, which may make it difficult for us to make
payments on the Notes if PMI or PMI Services becomes insolvent or bankrupt.

We have been advised by our Mexican counsel, our
Netherlands counsel, and our Cayman Islands counsel that transfers of eligible receivables under the receivables purchase agreement should qualify as sales under the laws of those jurisdictions. However, no court precedent in those jurisdictions
directly supports that advice. Therefore, we cannot assure you that a court in any of these jurisdictions would view the transfer of eligible receivables from PMI to PMI Services, or from PMI Services to us, as sales. If the transfer is not treated
as a sale, we may have difficulty making payments on the Notes if PMI or PMI Services becomes insolvent or subject to bankruptcy or equivalent proceedings. In addition, in any such bankruptcy or equivalent proceeding, either PMI Services or we may
be stayed in taking action with respect to the receivables and required to have our interests in the receivables determined by a court, which would likely delay and could result in reductions in payments on the Notes.

Furthermore, our ability to make payments on the Notes could be limited if a court were to void a transfer by which we received eligible receivables. A
court could void a transfer of eligible receivables if the transfer were made:



| |  |  | with the intent to hinder, delay or defraud PMI, PMI Services or their creditors; or
| | - |  | ------------------------------------------------------------------------------------



| |  |  | at a time when PMI or PMI Services was insolvent, deemed insolvent or contemplating insolvency if the transfer were made without payment of a reasonable purchase price.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If the transfer were considered void, PMI Services or we could be treated as having an unsecured claim for the amount paid
to purchase the receivables.

1. Treatment Under Mexican and Cayman Islands Law. Instead of treating the transfers of eligible
receivables from PMI to PMI Services and from PMI Services to us as sales, courts applying Mexican or Cayman Islands law could treat these transfers in two other ways:



| |  |  | they could treat the transfer of eligible receivables as assignments of collateral as security from PMI to PMI Services and from PMI Services to us; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | they could treat the transfer as giving rise to an unsecured claim for the amounts that we paid to PMI Services, and that PMI Services paid to PMI. Claims for these amounts would
rank equally in right of payment with all other unsecured obligations of PMI and PMI Services. Such an unsecured claim against PMI would be subordinate to claims of PMIs creditors preferred under Mexican bankruptcy law.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

Although there are no court precedents supporting the foregoing treatment, if the transfer is treated in
either of these ways, it is likely that there would be a delay and, possibly, a reduction in payment on the Notes.

You should also be
aware that because PMI is a Mexican corporation, it is subject to Mexican bankruptcy law. Under Mexican bankruptcy law, the bankruptcy trustee may discontinue some activities of a bankrupt company and refuse to perform some contractual obligations
of that company upon court approval. In particular, if PMI were declared bankrupt by a Mexican bankruptcy court, the bankruptcy trustee could discontinue sales of crude oil upon court approval. This discontinuation would terminate the generation of
future eligible receivables we had already purchased and thus substantially reduce our ability to make payments under the Notes.

The
bankruptcy trustee could also refuse to continue to sell additional eligible receivables to PMI Services under the receivables purchase agreement. PMI Services could file a claim against the estate of PMI seeking a remedy for PMIs failure to
generate future eligible receivables that we had already purchased. However, even if a court were to recognize PMI Services claim, it would qualify as an unsecured claim for the amount PMI Services paid to PMI, in which case the claim would
rank equally in right of payment with all other unsecured obligations of PMI, and would be subordinate to claims of creditors preferred under Mexican bankruptcy law. The amount recoverable under this claim, if any, would depend on the outcome of the
bankruptcy proceedings.

2. Treatment Under Netherlands Law. If PMI Services were to enter bankruptcy proceedings under Netherlands
law, Netherlands law may limit our rights to eligible receivables that we purchased prior to the bankruptcy proceedings but that PMI generated after those proceedings began. In this case, Netherlands law would grant us only the right to recover the
purchase price we paid to PMI Services for the eligible receivables. This right to recover the relevant purchase price would rank equally with all other unsecured indebtedness or other obligations of PMI Services. If PMI Services assets were
inadequate to cover all the claims, we could only recover our pro rata share of the assets.

3. Treatment Under New York Law. If PMI
or PMI Services were to become the subject of a bankruptcy proceeding and if the court were to apply New York law, the court might decide to recharacterize each transfer of eligible receivables as the provision of collateral to secure a loan. The
court would therefore consider us to be a creditor of PMI Services, and PMI Services to be a creditor of PMI. In our capacity as creditors, we and PMI Services might be treated as having a security interest in the eligible receivables that we had
already purchased.

We cannot predict what effect, if any, this determination would have in a bankruptcy proceeding of PMI or PMI Services
in Mexico, the Cayman Islands or The Netherlands because there is no legal provision or precedent in those jurisdictions directly applicable to the sale transaction described in this annual report. Moreover, if a bankruptcy proceeding of PMI or PMI
Services were brought in the United States and the court were to recharacterize the transfer as described above, we can give no assurance that the court would find us to be entitled to assets sufficient to cover payments on the Notes or that these
payments could be made on a timely basis.

To the extent that the time between the sale and generation of future receivables increases, the
risks described in this risk factor will be borne for a longer period. See Item 5. Operating and Financial Review and ProspectsManagements Discussion and Analysis of Financial Condition and Results of OperationsLiquidity
and Capital Resources.

Risks Related to the Obligations of Pemex Finance, PMI Services, PMI and PEP

The trustee may not be aware of all relevant events possibly leading to an event of default.

We cannot guarantee that the trustee representing holders interest in the Notes will learn of events that may give rise to an event of default under
the Notes. We have agreed to a number of financial covenants under the fiscal agency agreement. We, PEP, PMI and PMI Services have agreed to other covenants under the fiscal



5

##### Table of Contents

agency agreement, the indenture and the receivables purchase agreement. Failure to comply with those covenants, on our part or on the part of PEP, PMI or PMI
Services, will give rise to an event of default under the Notes.

However, the servicer, the fiscal agent and the collection agent have no
duty to monitor compliance with the covenants. Further, none of them has any duty to inform the trustee or anyone else of a violation of the covenants. This means that the trustee may not be aware that an event of default has occurred or is about to
occur, and therefore may not be able to make demands of us, PEP, PMI and PMI Services that can be made in an event of default and that might be in the interest of holders of Notes. For a description of risks that arise after an event of default has
occurred, see the following risk factor.

If an event of default occurs, holders of Notes will have recourse only to us and we cannot guarantee that
these holders will receive all of the money to which they are entitled.

If an event of default occurs, holders of Notes may not
receive all of the money to which they are entitled under the Notes. An event of default may prompt the acceleration of the maturity of the Notes of any series. If this occurs, subject to some exceptions, holders of Notes will receive an amount of
the accelerated payments of principal and interest equal to their proportionate share of the amounts on deposit in the retention account maintained by the fiscal agent. However, the amounts distributed from the retention account over time may not be
sufficient to pay all of the money to which holders of Notes are entitled. See Item 4. Information on the CompanyDescription of Principal AgreementsThe Fiscal Agency AgreementFunding and Administration of Retention
Account.

The Notes are solely our obligation. They are not obligations of, or guaranteed by, the Mexican Government, PEMEX, PEP,
PMI, PMI Services, any other affiliate of PEMEX, any designated customer or any other party. Moreover, in an event of default, holders of Notes will not have any recourse against any of our shareholders, directors or officers.

We have limited control over PMI in its capacity as servicer.

PMI has been named the servicer. We may remove PMI as servicer in some limited circumstances. However, beyond those circumstances, we have no control over the manner in which PMI or any subsequently named servicer
carries out its duties as servicer.

As the servicer, PMI services, manages, administers and collects the eligible receivables that we have
purchased. PMI has agreed not to resign as servicer so long as:



| |  |  | the servicing and collection agency agreement remains in effect, or
| | - |  | -------------------------------------------------------------------



| |  |  | any document governing the transactions described in this annual report requires that eligible receivables be generated, sold to us and collected.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------

We cannot ensure that any subsequently named servicer will be able to carry out its duties at the same level of efficiency as PMI. See Item 4.
Information on the CompanyDescription of Principal AgreementsThe Servicing and Collection Agency AgreementDuties of the Servicer.

Because we are a foreign company, holders of the Notes may not be able to effect service of process on, or enforce a judgment against, us.

We are incorporated under the laws of the Cayman Islands, and all of our directors and officers, as well as some of the experts named in this annual report, reside outside the United States. As a result, you may not
be able to effect service of process on us, our directors or officers or the experts within the United States. You also may not be able to enforce in the United States judgments obtained in the United States against us or our directors or officers,
if those judgments are not based on Cayman Islands law. Accordingly, you may not be able to enforce in the United States any judgments based on the civil liability provisions of the federal securities laws of the United States.

Nevertheless, we do not know whether you would be able to enforce liabilities based on the federal securities laws of the
United States in the Cayman Islands. We also do not know whether Cayman Islands courts would enforce judgments of United States courts based on the civil liability provisions of the federal securities laws of the United States.

Risks Related to PEMEX, PEP and PMI

The Mexican Government
controls PEMEX; it could limit PEMEXs ability to satisfy its external debt obligations, and it could privatize PEMEX.

Petróleos Mexicanos is a decentralized public entity of the Mexican Government, and therefore the Mexican Government controls PEMEX, as well as its annual budget, which is approved by the Mexican Congress. However, our financing
obligations do not constitute obligations of and are not guaranteed by the Mexican Government. The Mexican Government has the power to intervene directly or indirectly in PEMEXs commercial affairs. Intervention by the Mexican Government could
adversely affect PEMEX and thereby adversely affect our ability to make payments under the Notes.

The Mexican Government would have the
power, if federal law and the Constitución Política de los Estados Unidos Mexicanos(the Political Constitution of the United Mexican States) were amended, to privatize or transfer all or a portion of PEMEX or its assets. A
privatization could adversely affect PEMEXs production, cause a disruption in its workforce and its operations, and cause it to default on certain obligations. See also Risks Related to Mexico below.

Crude oil and natural gas prices are volatile, and low oil and natural gas prices negatively affect PEMEXs income.

International crude oil and natural gas prices are subject to global supply and demand, and fluctuate due to many factors beyond PEMEXs control.
These factors include competition within the oil and natural gas industry and with other industries in supplying clients with competing commodities, international economic trends, exchange rate fluctuations, expectations of inflation, domestic and
foreign government regulations, political and other events in major oil and natural gas producing and consuming nations and actions taken by Organization of the Petroleum Exporting Countries (OPEC) members and other oil exporting countries.

Maya crude oil is particularly vulnerable to fluctuations in international crude oil prices. Because Maya crude oil is a heavy sour crude
oil with a smaller, more concentrated market, it is more susceptible to drops in international crude oil demand. In addition, when prices of lighter crude oils decrease, Maya crude oil becomes less competitive because it costs more to refine it.
Historically, the weighted average price of Maya crude oil exported by PEMEX has fluctuated significantly (for example, from U.S.$25.33 per barrel in 1984 to U.S.$14.08 in 1999). The weighted average price per barrel of Maya crude oil exported by
PEMEX during 2005 was U.S.$40.61.

When international crude oil and natural gas prices are low, PEMEX earns less export sales revenue, and,
therefore, earn less income because its costs remain roughly constant. Conversely, when crude oil and natural gas



7



---

##### Table of Contents

prices are high, PEMEX earns more export sales revenue and its income increases. As a result, future fluctuations in international crude oil and natural gas
prices will directly affect PEMEXs results of operations and financial condition.

If Maya crude oil prices decline for a substantial
period below certain levels, PEMEX and PMI might be unable to cause the monthly average amount of eligible receivables of designated customers generated by PMI to achieve the levels needed to maintain the debt service coverage ratio required under
the fiscal agency agreement and, ultimately, to make our payments on the Notes.

Very low crude oil prices, in particular, could negatively
affect PEPs ability to maintain its levels of production and therefore the generation of receivables.

The Mexican Government has entered into
agreements with other nations to limit production.

Although Mexico is not a member of OPEC, it has entered into agreements with
OPEC and non-OPEC countries to reduce global crude oil supply. PEMEX does not control the Mexican Governments international affairs and the Mexican Government could agree with OPEC or other countries to reduce PEMEXs crude oil production
or exports in the future. A reduction in PEMEXs oil production and/or exports could reduce PEMEXs revenues.

The Mexican nation, not
PEMEX, owns the hydrocarbon reserves in Mexico.

The Political Constitution of the United Mexican States provides that the Mexican
nation, not PEMEX, owns the petroleum and other hydrocarbon reserves located in Mexico. Although Mexican law gives Petróleos Mexicanos and the subsidiary entities the exclusive right to exploit Mexicos hydrocarbon reserves, it does not
preclude the Mexican Congress from changing current law and assigning some or all of these rights to another company. Such an event would adversely affect PEMEXs ability to generate income.

Information on Mexicos hydrocarbon reserves is based on estimates, which are uncertain and subject to revisions.

The information on oil, gas and other reserves set forth in the annual reports on Form 20-F of Petróleos Mexicanos is based on estimates. Reserves
valuation is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner; the accuracy of any reserve estimate depends on the quality and reliability of available data,
engineering and geological interpretation and subjective judgment. Additionally, estimates may be revised based on subsequent results of drilling, testing and production. Therefore, proved reserve estimates may differ materially from the ultimately
recoverable quantities of crude oil and natural gas. PEP revises its estimates of Mexicos hydrocarbon reserves annually, which may result in material revisions to PEMEXs estimates of Mexicos hydrocarbon reserves.

PEMEX is an integrated oil and gas company and is exposed to production, equipment and transportation risks.

PEMEX is subject to several risks that are common among oil and gas companies. These risks include production risks (fluctuations in production due to
operational hazards, natural disasters or weather, accidents, etc.), equipment risks (relating to the adequacy and condition of our facilities and equipment), and transportation risks (relating to the condition and vulnerability of pipelines and
other modes of transportation).

More specifically, PEMEXs business is subject to the risks of explosions in pipelines, refineries,
plants, drilling wells and other facilities, hurricanes in the Gulf of Mexico and other natural or geological disasters and accidents, fires, and mechanical failures. The occurrence of any of these events could result in personal injuries, loss of
life, equipment damage and environmental damage, and require clean-up and repair expenses.

Although PEMEX has purchased insurance policies
covering some of these risks, these policies may not cover all liabilities, and insurance may not be available for all risks.

##### Table of Contents

Petróleos Mexicanos and the subsidiary entities pay special taxes, duties and dividends to the Mexican
Government.

The Mexican Government taxes Petróleos Mexicanos and its subsidiary entities heavily. In 2005, approximately
67.2% of their sales revenues were used to pay taxes to the Mexican Government. The Mexican Congress determines the rates of taxes and duties applicable to PEMEX from year to year depending on a variety of factors. In addition, Petróleos
Mexicanos is obligated to pay minimum guaranteed dividends to the Mexican Government.

PEMEX must make significant capital expenditures to maintain
its current production levels and increase Mexicos hydrocarbon reserves. Mexican Government budget cuts, reductions in PEMEXs income and inability to obtain financing may limit PEMEXs ability to make capital investments.

PEMEX invests funds to increase the amount of extractable hydrocarbon reserves in Mexico. PEMEX also continually invests capital to
enhance its hydrocarbon recovery ratio and improve the reliability and productivity of PEMEXs infrastructure. PEMEXs ability to make these capital expenditures is limited by the substantial taxes that it pays and cyclical decreases in
its revenues primarily related to lower oil prices. In addition, budget cuts imposed by the Mexican Government and the availability of financing may also limit its ability to make capital investments.

PEMEXs compliance with environmental regulations in Mexico could result in material adverse effects on its results of operations.

A wide range of general and industry-specific Mexican federal and state environmental laws and regulations apply to PEMEXs operations. Numerous
Mexican Government agencies and departments issue rules and regulations which are often difficult and costly to comply with and which carry substantial penalties for non-compliance. This regulatory burden increases PEMEXs costs because it
requires PEMEX to make significant capital expenditures and limits its ability to extract hydrocarbons resulting in lower revenues. At December 31, 2005, PEMEX estimated and accrued environmental liabilities totaled Ps. 1,727 million.

PEMEX publishes less U.S. GAAP financial information than U.S. companies are required to file with the U.S. Securities and Exchange Commission.

PEMEX prepares its financial statements according to Mexican GAAP, which differs in certain significant respects from U.S. GAAP.
The most important of the material items generating a difference between operating results under U.S. and Mexican GAAP are the accounting methodologies for the treatment of exploration and drilling costs, pension and seniority premiums, post
retirement benefit obligations, financial instruments, capitalized interest, depreciation, impairment of fixed assets, profit in inventory and accounting for its investment in shares of Repsol YPF, S.A. As a foreign issuer, PEMEX is not required to
prepare quarterly U.S. GAAP financial information, and PEMEX therefore generally prepares U.S. GAAP information on a yearly basis only. As a result, there may be less or different publicly available information about PEMEX than there is about U.S.
issuers.

Changes in Mexican taxes may occur which may allow us to redeem the Notes without paying a premium to holders of Notes.

As long as the Treaty to Avoid Double Taxation between Mexico and The Netherlands is in force, PMI would not be subject to withholding tax in Mexico
with respect to the payments under the Notes. However, Mexican tax rules are approved on an annual basis, and the Treaty to Avoid Double Taxation between Mexico and The Netherlands may be amended. Therefore, we cannot assure you that the applicable
legal and treaty provisions will remain in effect. Moreover, additional taxes may apply to the transactions described in this annual report. Accordingly, you should be aware that these transactions, including payments under the Notes, may be subject
to Mexican taxes in the future.

##### Table of Contents

You should also be aware that, under the terms of the supplemental indentures under which the Notes were
issued, we have the right to redeem the Notes in some circumstances without paying a make whole premium to holders of the Notes to account for any losses they may suffer because of the early redemption. We can redeem the Notes without paying holders
this premium if:



| |  |  | any change or amendment in applicable law, including Mexican law or its interpretation, obliges us to increase the additional amounts that we are required to pay on the Notes to
ensure that the net payment received by each holder after any withholding or deduction for tax purposes equals the payment that would have been received in the absence of the withholding or deduction, and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we, PMI Services, PMI, PEP or Petróleos Mexicanos, as the case may be, cannot avoid this obligation by taking reasonable available measures.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------

Petróleos Mexicanos, PEP or PMI may claim some immunities under the Foreign Sovereign Immunities Act and Mexican law, and your ability to sue or recover may
be limited.

Petróleos Mexicanos, PEP and PMI are decentralized public entities of the Mexican Government. Accordingly, you
may not be able to obtain a judgment in a U.S. court against them unless the U.S. court determines that they are not entitled to sovereign immunity with respect to that action. In addition, Mexican law does not allow attachment prior to judgment or
attachment in aid of execution upon a judgment by Mexican courts upon the assets of Petróleos Mexicanos or the subsidiary entities. As a result, your ability to enforce judgments against Petróleos Mexicanos, PEP and PMI in the courts
of Mexico may be limited. We also do not know whether Mexican courts would enforce judgments of U.S. courts based on the civil liability provisions of the U.S. federal securities laws. Therefore, even if you were able to obtain a U.S. judgment
against Petróleos Mexicanos, PEP or PMI, you might not be able to obtain a judgment in Mexico that is based on that U.S. judgment. Moreover, you may not be able to enforce a judgment against their property in the United States except under
the limited circumstances specified in the Foreign Sovereign Immunities Act. Finally, if you were to bring an action in Mexico seeking to enforce the obligations of Petróleos Mexicanos, PEP or PMI, including obligations under documents
related to the receivables and the letter agreement between us and PEMEX, satisfaction of those obligations may be made in pesos, pursuant to the laws of Mexico.

The directors and officers of PEMEX, as well as some of the experts named in this annual report, reside outside the United States. Substantially all of PEMEXs assets and those of most of its directors, officers
and experts are located outside the United States. As a result, you may not be able to effect service of process on its directors or officers or those experts within the United States.

Risks Related to Mexico

Economic conditions and government policies in Mexico may have a material impact on
PEMEXs and our operations.

A deterioration in Mexicos economic conditions, social instability, political unrest or
other adverse social developments in Mexico could adversely affect PEMEXs business and financial condition. Those events could also lead to increased volatility in the foreign exchange and financial markets, thereby affecting our and
PEMEXs ability to obtain and service foreign debt. In addition, the Mexican Government may cut spending in the future. These cuts could adversely affect PEMEXs business, financial condition and prospects. In the past Mexico has
experienced several periods of slow or negative economic growth, high inflation, high interest rates, currency devaluation, and other economic problems. These problems may reemerge in the future, and could adversely affect PEMEXs business and
our ability to service our debt.

Changes in exchange rates or in Mexicos exchange control laws may hamper our ability to make payments on the
Notes.

While the Mexican Government does not currently restrict the ability of Mexican companies or individuals to convert pesos
into dollars or other currencies, in the future, the Mexican Government could impose a



10



---

##### Table of Contents

restrictive exchange control policy, as it has done in the past. We cannot assure you that the Mexican Government will maintain its current policies with
regard to the peso or that the pesos value will not fluctuate significantly in the future. The peso has been subject to significant devaluations against the U.S. dollar in the past and may be subject to significant fluctuations in the future.
Mexican Government policies affecting the value of the peso could prevent Petróleos Mexicanos, PEP or PMI from paying their foreign currency obligations. If they do stop paying their foreign currency obligations, PMI may be unable to continue
generating or servicing eligible receivables, which may in turn render us unable to make payments to holders of the Notes.

In the future,
we and PEMEX may incur additional indebtedness denominated in U.S. dollars or other currencies. Declines in the value of the peso relative to the U.S. dollar or other currencies may increase PEMEXs and our interest costs in pesos and result in
foreign exchange losses.

Political conditions in Mexico could materially and adversely affect Mexican economic policy and, in turn, PEMEXs
operations.

Political events in Mexico may significantly affect Mexican economic policy and, consequently, PEMEXs operations.
The national elections held in 2000 ended 71 years of rule by a one-party state and resulted in the increased representation of opposition parties in the Mexican Congress. No political party has an absolute majority in either chamber of the Mexican
Congress. There have not been any material adverse repercussions for PEMEX resulting from these political changes.

Presidential and
federal congressional elections in Mexico will be held in July 2006. The Mexican presidential election will result in a change in administration, as presidential reelection is not permitted in Mexico. As a result, we cannot predict whether changes
in Mexican governmental policy will result from a change in administration. Such changes may adversely affect economic conditions or the industry in which PEMEX operates in Mexico and therefore PEMEXs results of operations and financial
position.

Risks Related to the Notes

The market
for the Notes may not be liquid.

The Notes are primarily traded in the over-the-counter market. The Notes are not listed on any
securities exchange other than the Luxembourg Stock Exchange and are not quoted through an automated quotation system. We can make no assurance as to the liquidity of or trading markets for the Notes. We cannot guarantee that holders of Notes will
be able to sell their Notes in the future. We also cannot guarantee that any sale would be at a price equal to or greater than the principal amount or initial offering price of the Notes. If the market for the Notes does not develop, holders of
Notes may be unable to resell the Notes for an extended period of time, if at all. Consequently, holders of the Notes may not be able to easily liquidate their investment, and the Notes may not be readily accepted as collateral for loans.

We may issue additional debt, which may affect the holders of Notes negatively.

From time to time, we may issue additional debt securities or incur other indebtedness. If we issue additional debt, our existing noteholders
proportional share in the proceeds from the retention account if an event of default or specified event under the fiscal agency agreement occurs will be smaller. See Item 4. Information on the CompanyDescription of Principal
AgreementsThe Fiscal Agency AgreementEvents of Default and Specified Events. Further, there may be more creditors pursuing our assets if we default or become bankrupt. Thus, our assets would be divided among a
greater number of creditors.

Actual Results of Our Operations May Differ From Those Contained in Forward-Looking Statements.

This annual report contains forward-looking statements. These forward-looking statements reflect our views with respect to future events and financial
performance. However, actual results could differ materially from the results projected in the forward-looking statements as a result of the risks described above.

You can identify these forward-looking statements by, among other things, the use of forward-looking
language, such as believe, expect and anticipate and similar expressions. These statements are based on current plans, estimates and projections. Therefore you should not place undue reliance on them.
Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update any of them publicly in light of new information or future events.

Other Risk Factors

If we are not able to adequately implement the requirements of Section 404 of the
Sarbanes-Oxley Act of 2002 and are the subject of sanctions or investigation, our results of operations and our ability to provide timely and reliable financial information may be adversely affected.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002 and related
regulations implemented by the SEC and the Public Company Accounting Oversight Board, or PCAOB, are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time consuming. We will be
evaluating our internal control over financial reporting to allow management to report on, and our registered independent public accounting firm to attest to, our internal controls over financial reporting. We will be performing the system and
process evaluation and testing (and any necessary remediation) required to comply with the management certification and auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, which we are required to comply within our annual
report which we will file in 2008 for our 2007 fiscal year. As a result, we expect to incur substantial additional expenses and diversion of managements time. While we anticipate being able to fully implement the requirements relating to
internal controls and all other aspects of Section 404 by our deadline, we cannot be certain as to the timing of completion of our evaluation, testing and any remediation actions or the impact of the same on our operations since there is
presently no precedent available by which to measure compliance adequacy. If we are not able to implement the requirements of Section 404 in a timely manner or with adequate compliance, we might be subject to sanctions or investigation by
regulatory authorities such as the SEC or the PCAOB. Any such action could adversely affect our financial results. In addition, if we fail to develop and maintain effective controls and procedures, we may be unable to provide the financial
information in a timely and reliable manner.

DESCRIPTION OF
BUSINESS

Pemex Finance Ltd. is a limited liability company incorporated under the laws of the Cayman Islands on November 18,
1998. We are tax exempt under the laws of the Cayman Islands and we have a limited operating history.

We are a special purpose financing
vehicle formed as part of a program established to finance the capital expenditures of PEMEX. PEMEX is Mexicos state oil and gas company. It is the largest company in Mexico and one of the largest oil and gas companies in the world. During
2005, PEP, through PMI, Petróleos Mexicanos marketing affiliate, exported an average of 1,817.1 tbpd of crude oil. Of this amount, 72.6%, or 1,319 tbpd, consisted of exports to designated customers of PMI of crude oil designated as
Maya crude oil as described below in The Designated Customers and Eligible ReceivablesCrude Oil.

Our
authorized share capital consists of 1,000 ordinary shares, U.S.$1.00 par value per share, all of which have been issued and paid. All of our outstanding shares are owned by BNP Paribas Bank as trustee for the Pemex Finance Trust, pursuant to the
terms of a charitable trust created by a declaration of trust dated December 1, 1998 under the laws of the Cayman Islands. Our registered office is at BNP Paribas Bank & Trust Cayman Limited, P.O. Box 10632APO, 3rdFloor, Royal Bank House, Shedden Road, George Town, Grand

NY 10178-0061, is our agent for service of process.

Business

Generally, our business consists of using the proceeds of the debt we issue to purchase accounts receivable which have been generated or will be generated in the future through the sale of crude oil to the current
designated customers of PMI. PMI purchases the crude oil that it sells to these designated customers from PEP, Petróleos Mexicanos exploration and production affiliate. The sale of accounts receivable from PMI to us takes place in two
steps. First, PMI sells the accounts receivable of designated customers to PMI Services, an affiliate of Petróleos Mexicanos organized under the laws of The Netherlands. Second, PMI Services, in turn, sells those receivables to us. We buy
both receivables which have been generated by PMI and receivables which PMI will generate in the future.

As of December 1, 1998, we
entered into a contract called the receivables purchase agreement with the exploration and production and marketing arms of PEMEX. Under this contract, we have the right to purchase, from time to time, accounts receivable that have been generated,
or will be generated in the future, from the exports by PMI of crude oil to certain designated customers. By acquiring such eligible receivables on an on-going basis under the receivables purchase agreement, we generate the cash flows required to
service our debt, including the Notes. Our business is limited to the purchase of eligible receivables of designated customers under the receivables purchase agreement and the issuance of unsecured debt.

We financed our initial purchase of the accounts receivable with the net proceeds of notes we issued under a senior indenture on December 14, 1998
in an aggregate amount of U.S.$1.5 billion together with funds provided to us by Petróleos Mexicanos. We refer to the notes issued on December 14, 1998 as the 1998 notes. We have issued the following additional debt:



| |  |  | in February 1999, we issued fixed rate notes in an aggregate amount of U.S.$1.0 billion, which we refer to as the February 1999 notes, and floating rate notes in an
aggregate amount of U.S.$100.0 million, which we refer to as the February 1999 floating rate notes;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in July 1999, we issued fixed rate notes in an aggregate amount of U.S.$1.275 billion, which we refer to as the July 1999 notes, and additional fixed rate and floating
rate notes in an aggregate amount of U.S.$175 million, which we refer to as the July 1999 additional issuances; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in February 2000, we issued fixed rate notes in an aggregate amount of U.S.$950 million, which we refer to as the February 2000 notes.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------

When we wish to refer to the 1998 notes, the February 1999 notes, the February 1999 floating rate notes, the July 1999 notes, the July 1999 additional
issuances and the February 2000 notes together, we refer to the Notes.

We used the net proceeds of the Notes we issued
subsequent to the issuance of the 1998 notes, as well as additional funds provided by Petróleos Mexicanos through our subordinated debt, to finance additional purchases of accounts receivable. We may in the future issue additional debt
securities or borrow money and use the proceeds to purchase additional existing accounts receivable or accounts receivable that will be generated in the future, in accordance with the receivables purchase agreement.

Under a contract called the servicing and collection agency agreement, the collections on accounts receivable we purchase are, absent special
circumstances, transferred to us. We use these collections to service our debt, pay our operating expenses, maintain a liquidity facility with the fiscal agent and purchase additional accounts receivable. In this annual report, when we refer to the
fiscal agent, we mean JPMorgan Chase Bank, N.A., and any of its successors or any other fiscal agent which is appointed in accordance with the terms of the fiscal agency agreement.

##### Table of Contents

All amounts paid by us as the purchase price for accounts receivable under the receivables purchase
agreement, regardless of whether the source of such funds is money that we borrow or collections from accounts receivable previously purchased by us, are applied first to purchase any existing eligible receivables in the order in which they are
generated and then to purchase eligible receivables which will be generated in the future, in the order in which they are generated.

| | - |  | ---------------------------------------------------------------

See Item 5. Operating and Financial Review and Prospects. The market for crude oil is subject to price volatility and our business and financial condition depend to a large degree on the international prices for crude oil.
PMIs crude oil exports to the United States are largely comprised of heavy sour crude oil.

##### Table of Contents

The following summarizes the principal provisions of the principal agreements governing our business
and the flow of funds; the numbers correspond to the numbers in the chart on the previous page. The descriptions are not in chronological order. See Description of Principal Agreements for a more detailed description of these
principal agreements. See also the section entitled Glossary of Certain Defined Terms Used Primarily Under the Captions Description of the Principal Agreements and Description of the Indenture where we define the
capitalized terms that appear in this annual report.

Throughout this annual report, when we refer to the transaction documents or the
documents governing our business, we mean the fiscal agency agreement, each of our debt agreements, the receivables purchase agreement, the servicing and collection agency agreement, the letter agreement, the designated customer notices, the crude
oil sale agreement and any other documents delivered in connection with any of these agreements. For a more detailed discussion of the meaning of the terms designated customer, eligible customer, eligible
receivable, purchased receivable and crude oil as used in this annual report see The Designated Customers and Eligible Receivables.

The Principal Agreements

1.
The Crude Oil Sale Agreement. PEP sells crude oil to PMI under a crude oil sale agreement which has been in place since November 1, 1994. PEP and PMI may not terminate the crude oil sale agreement prior to the termination of the
receivables purchase agreement.

2. The Receivables Purchase Agreement. We, PEP, PMI and PMI Services are parties to the receivables
purchase agreement under which:



| |  |  | PEP agrees that during any 90 day period it will export at least 90% of its total exports of crude oil through PMI;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | PMI agrees to sell eligible receivables, including any current eligible receivables and eligible receivables that will be generated in the future, to PMI Services upon our request.
PMI Services agrees to sell those same current and future eligible receivables to us contemporaneously with its purchase of them. The purchase price of the eligible receivables is determined on the basis of a discount rate calculated as set forth in
the receivables purchase agreement;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PMI agrees to ensure that the monthly average amount of designated customers eligible receivables that PMI generates during any consecutive twelve month period that are not
otherwise pledged or encumbered represents at least the lesser of:
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 20 million barrels of Maya crude oil, and
| | - |  | -----------------------------------------



| |  |  | 80% of PMIs total eligible receivables generated from sales of Maya crude oil;
| | - |  | -------------------------------------------------------------------------------



| |  |  | We, PMI and PMI Services agree that if the monthly average amount of PMIs exports of Maya crude oil to designated customers for the six months prior to any date is less than
450 tbpd, on our request, PMI will sell to PMI Services designated customers receivables generated in connection with the export of crude oil other than Maya crude oil, and PMI Services will sell them to us; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PEP, PMI and PMI Services agree that if PMI becomes insolvent, PEP will export at least 90% of its total exports of crude oil through PMI Services.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------

3. The Fiscal Agency Agreement. We entered into the fiscal agency agreement with The Chase Manhattan Bank (now JPMorgan Chase Bank, N.A.), as the
fiscal agent and paying agent, and Chase Manhattan Bank Luxembourg S.A. (now J.P. Morgan Bank Luxembourg S.A.), as paying agent in Luxembourg. We make interest and principal payments on all of our outstanding debt, including the Notes, through the
fiscal agent. Under the fiscal agency agreement, we agree, among other things, to:



| |  |  | comply with specified financial covenants;
| | - |  | ------------------------------------------



| |  |  | limit our activities to the purchase of existing and future receivables and the issuance of debt;
| | - |  | -------------------------------------------------------------------------------------------------



16



---

##### Table of Contents

| |  |  | use the net proceeds of any debt we issue or other amounts we borrow only to purchase existing and future eligible receivables, service or refinance existing debt, or to cover
permitted corporate expenses;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | establish and maintain a liquidity facility with the fiscal agent in an amount at least equal to the total amount of scheduled debt service we are next scheduled to pay under each
of our debt agreements. We may fund the liquidity facility with cash, certain permitted investments, or one or more letters of credit. For a more detailed description, see the section entitled Description of Principal AgreementsThe
Fiscal Agency AgreementLiquidity Facility; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintain a retention account with the fiscal agent, to which the collection agent will transfer money that would otherwise come to us if one of several specified events occurs,
including some agreed-upon events of default. For more information on events of default, see Description of Principal AgreementsThe Fiscal Agency AgreementEvents of Default. Until the fiscal agent notifies the
collection agent to cease doing so, the amount it transfers to the retention account on each business day will be equal to either:
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in the case of some agreed-upon events of default, 100% of all the money the designated customers paid into the collection account on the preceding business day on purchased
receivables; or
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in all other cases, 25% of the difference between:
| | - |  | --------------------------------------------------



| |  |  | all the money the designated customers paid on the purchased receivables into the collection account on the preceding business day; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the aggregate amount of debt service we paid on the preceding business day, other than accelerated debt service.
| | - |  | ----------------------------------------------------------------------------------------------------------------

On any business day, amounts in the retention account are used to pay accelerated debt service, if any, that is due and payable on that day. Holders of
our Indebtedness receive payments from the retention account proportionate to the amounts of accelerated debt service we owe them.

4.
The Designated Customer Notices. We, Petróleos Mexicanos, PEP, PMI and PMI Services jointly notified each designated customer through a designated customer notice that the eligible receivables owed by the designated customer may have
been sold to us.

5. The Servicing and Collection Agency Agreement. We entered into the servicing and collection agency agreement
with PMI Services, PMI, Petróleos Mexicanos and UBS AG. Under this agreement, UBS AG acted as the initial collection agent. On October 1, 1999, Standard Chartered Bank replaced UBS AG as collection agent, in accordance with the
terms of the servicing and collection agency agreement. Under the servicing and collection agency agreement, PMI acts as the servicer. The servicer services, manages, administers and collects any eligible receivables that are sold as described
above.

6. The Subordinated Debt. Petróleos Mexicanos provided us with subordinated debt for our initial capitalization and
again each time we issued notes as necessary to maintain the required debt to equity ratio specified in the transaction documents.

7.
The Letter Agreement. Petróleos Mexicanos agreed with us in a letter agreement to cause PEP, PMI Services and PMI to perform their material obligations under the receivables purchase agreement and the crude oil sale agreement under
which PEP sells crude oil to PMI.

Under the fiscal agency agreement, our performance of our obligations is intended to be for the benefit
of the trustee and any other agent or representative of holders of our Indebtedness named under any of our debt agreements. The receivables purchase agreement and the servicing and collection agency agreement are similar: they provide that
PEPs, PMIs, PMI Services and our rights and performance under those agreements are intended for the benefit of the trustee and any other agent or representative of holders of our Indebtedness.

The Flow of Funds Under the Agreements

1. Petróleos Mexicanos provided us with subordinated debt for our initial capitalization and again each time we issued notes.

2. We issued four series of fixed rate notes in December 1998, four series of fixed rate notes and one series of floating rate notes in February 1999,
five series of fixed rate notes and two series of floating rate notes in July 1999 and two series of fixed rate notes in February 2000. In the future we may issue additional debt.

3. We purchase the eligible receivables from PMI Services and PMI Services purchases the eligible receivables from PMI.

4. The designated customers make their payments on the receivables for the crude oil they purchase from PMI, whether or not for Maya crude oil, into the
collection account when payments are due.

5. The collection agent allocates the money received from the designated customers to us, PMI
Services, PMI and the retention account, if applicable, in accordance with the servicing and collection agency agreement. We fund and maintain the liquidity facility.

6. We make payments of principal and interest on our debt, including the Notes, to the holders when those payments are due. We buy additional receivables and cover our general corporate expenses, including any
insurance premiums.

7. We make periodic payments on our subordinated debt to Petróleos Mexicanos.

PMI Services

PMI Services is a company which was
organized on March 31, 1988 under the laws of The Netherlands. PMI Services is indirectly wholly-owned by Petróleos Mexicanos. PMI Services business is limited to purchasing eligible receivables from PMI at our request and selling
them to us.

Taxation of PMI Services

The 1969 Netherlands Corporate Income Tax Act imposes an annual corporate income tax on the taxable amount of a corporation resident in The Netherlands. As a company incorporated under the laws of The Netherlands, PMI
Services is deemed to be resident in The Netherlands for purposes of the Corporate Income Tax Act. Therefore, the profit derived by PMI Services in connection with its purchase and sale of eligible receivables is subject to Netherlands corporate
income tax. The Netherlands corporate income tax rate in 2005 was 27% on the first Euro 22,689 of taxable profit and 31.5% on the excess. The current Netherlands corporate income tax rate is 25.5% on the first Euro 22,689 of taxable profit and 29.6%
on the excess.

The taxable amount of a corporate taxpayer in The Netherlands is the taxable profit for the year, minus losses of certain
other years. Pursuant to Article 8b of the 1969 Netherlands Corporate Income Tax Act, taxable profit is determined on the basis of arms length principles if transactions are entered into with related parties.

Payments made by PMI Services to PMI for the purchase of eligible receivables are not subject to Netherlands withholding tax or value added tax.

Property, Plants and Equipment

We do
not own or lease any materially important physical properties or fixed assets.

The Designated Customers and Eligible Receivables

Our primary business is to purchase eligible receivables of designated customers of PMI that have been generated and that will be generated in the future.
We buy the eligible receivables from PMI Services, who, in turn, purchases the eligible receivables from PMI. The receivables purchase agreement governs the terms under

##### Table of Contents

which we purchase the receivables and under which the designated customers and the eligible receivables are selected. For a more detailed discussion of the
receivables purchase agreement, see Description of Principal AgreementsThe Receivables Purchase Agreement.

Crude Oil

When we use the term crude oil in this annual report, we mean extracted oil that has not been
refined, excluding condensates and natural gas liquids. Condensates are liquid hydrocarbons, such as ethane, propane, butane and certain pentanes, obtained from natural gas and recovered in surface separating facilities. Condensates also include
liquid hydrocarbons condensed in natural gas pipelines. Natural gas liquids include ethane, propane, butanes, pentanes and heavier paraffin hydrocarbons. The term crude oil refers to heavy crude oil with an American Petroleum Institute
(API) gravity less than or equal to 25° and light crude oil with API gravity higher than 25°. API gravity refers to the specific gravity, or density, of liquid petroleum products measured in degrees on the American Petroleum
Institute scale. On the API scale, oil with the least specific gravity has the highest API gravity. In addition, if all other things are equal, the higher the API gravity, the greater the value of the crude oil.

When we use the term Maya crude oil, we mean crude oil of 30° API gravity or less. Unless otherwise specified, the term includes crude
oil PMI sells under the name Maya as well as crude oil it sells under the name Altamira. When we use the term Isthmus, we mean light crude oil of 32° to 33° API gravity and 1.50% sulfur by weight. When we
use the term Olmeca, we mean very light crude oil, of 38° to 39° API gravity and 0.95% sulfur by weight.

Selection of the Designated Customers

As of December 31, 2005, 41 designated customers, including 37 United
States and Canadian companies, three Aruban companies and one Mexican company, have received and acknowledged a fully executed designated customer notice.

A designated customer notice is a notice in the form included in the receivables purchase agreement which, among other things, informs the customer that it must make its payments into the collection
account. The parties to the notice must sign it prior to our first purchase of receivables of that designated customer. Designated customer notices may only be modified with the consent of Petróleos Mexicanos and the fiscal agent in
accordance with the terms of each of our debt agreements, including the agreements governing the Notes (here, and throughout this annual report, debt agreements includes any indenture, loan, credit or reimbursement agreement, promissory
note or other instrument evidencing or governing our indebtedness).

Under the receivables purchase agreement, a customer is
any entity that purchases crude oil from PMI. The designated customers are those customers which (a) are listed in a schedule to the receivables purchase agreement and (b) have received and acknowledged a designated customer
notice. The primary criteria for selecting customers to include as designated customers is that they be a United States or a Canadian person who is a customer of PMI that purchases crude oil.

PMI may elect to, and in some circumstances must, add a new customer to the list of designated customers, so long as that customer is an eligible
customer as described below. More specifically, PMI has agreed that any person who is organized under the laws of the United States, any state of the United States or Canada and enters into a longterm contract with PMI for the purchase of Maya
crude oil shall be made a designated customer within 60 days of entering into that contract.

To add a new customer, PMI must deliver the
following documents to us, PMI Services, the servicer, the fiscal agent, the trustee and any other agent or representative of holders of our indebtedness:



| |  |  | an officers certificate;
| | - |  | -------------------------



| |  |  | a new schedule to the receivables purchase agreement listing all designated customers including the new customer; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | a fully-executed copy of the designated customer notice for the new customer, together with an acknowledgment signed by the new customer acknowledging receipt of the notice.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

We refer to the schedule to the receivables purchase agreement listing all designated customers, as
amended from time to time, as the designated customer list.

A customer may only become a designated customer if it is already
an eligible customer. In order to be an eligible customer, the customer must be:



| |  |  | listed on schedule I to the receivables purchase agreement as of December 1, 1998;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | a United States or Canadian entity; or
| | - |  | --------------------------------------



| |  |  | any other customer that PMI identifies to us and we find reasonably acceptable. In this case, the customers principal assets must be located outside of Mexico. Further, at the
time PMI identifies the customer as a designated customer, an opinion of counsel must be delivered to us stating, among other things, that the designated customer notice has been completed and signed by the customers authorized signatory and
that the notice constitutes a valid, binding and enforceable obligation of the customer.

##### Table of Contents

As of December 1, 1998, we had 21 designated customers. Each of these customers had entered into oil
supply contracts with PMI and accounted for a limited portion of the pool of eligible receivables purchased by us. Since 1998, PMI has elected to add new customers to the designated customer list, causing the aggregate number of customers listed
therein to increase from 21 to 41. Over time, certain of these designated customers have stopped purchasing Maya crude oil from PMI. Other customers have merged (for example, (i) Conoco Inc. merged into Conoco Phillips Company, (ii) Exxon
Trading Company International and Mobil sales and Supply Corporation merged into Exxon Mobil and (iii) The Premcor Refining Group, Inc. merged into Valero Energy Corporation) or assigned their contracts for the purchase of Maya crude oil to
other designated customers (for example, (i) CITGO International Supply Co. assigned its crude oil supply contract to CITGO Petroleum Corp. and (ii) Coastal Aruba Refining Company N.V and Coastal Petroleum N.V. assigned their crude oil
supply contract to Valero Refining Company-Aruba N.V.). As a result, the aggregate number of designated customers that purchased Maya crude oil from PMI in 2005 and in 2006 through May 31 decreased to 19 customers and 14 customers,
respectively.

The following table lists the designated customers that purchased Maya crude oil from PMI in 2005 and/or in 2006 through
May 31, and indicates the number of years each (or a predecessor or affiliate thereof) has been purchasing Maya crude oil, on a continuous or occasional basis, originally from Petróleos Mexicanos and, since 1989, from PMI:

The sole Mexican designated customer is an affiliate of Petróleos Mexicanos, P.M.I. Norteamérica, S.A. de C.V., which we refer to as PMI NASA. PMI NASA owns 50% of the Deer Park Refining
Limited Partnership. The remaining 50% of the partnership, which holds the Deer Park Refinery located in Texas, is owned by Shell Oil Company, the general manager of the partnership.

The reduction in the number of designated customers that purchase Maya crude oil from PMI, as well as fluctuations in the level of demand by each
customer, have caused the percentage of the total volume of accounts receivable sold to us represented by certain of our designated customers to increase.

During 2005, Chevron U.S.A. Inc., ExxonMobil Sales and Supply Corporation and Valero Marketing & Supply Co. each accounted for more than 10% of the total volumes of Maya crude oil sold to the designated

customers during that period. These designated customers or their affiliates are companies which are required to file periodic reports with the SEC under the
Securities Exchange Act of 1934. These reports are publicly available, and we refer you to them for information about these designated customers. In addition, the composition of the pool of eligible receivables of designated customers we own may
vary over time to reflect future fluctuations in the level of demand by each of the designated customers. As a result, certain designated customers may from time to time in the future represent higher percentages of the total volume of receivables
sold to us.

The Eligible Receivables

We have purchased and will continue to purchase only those receivables of designated customers that are eligible receivables under the receivables purchase agreement.

Under the receivables purchase agreement, a receivable is the indebtedness, payment obligation and accounts receivable that a particular
customer owes or will owe to PMI arising from its purchase of Maya crude oil, or, under limited circumstances, crude oil other than Maya crude oil. To qualify as a receivable, a bill of lading or invoice must have been issued to the customer. A
receivable includes:



| |  |  | all of PMIs rights and benefits which may arise from the foregoing indebtedness, payment obligation and accounts receivable;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | all associated accounts and general intangibles (each as defined under the Uniform Commercial Code as in effect in the jurisdiction of our chief executive offices);
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | all associated contract rights;
| | - |  | -------------------------------



| |  |  | any related property; with respect to each receivable, related property means:
| | - |  | --------------------------------------------------------------------------------

(a) PMIs interest in the crude oil it sold to the customer which gave rise to the receivable;

(b) all liens and property subject to the liens which are used to secure payment of the receivable, whether or not used to secure payment
in accordance with the contract giving rise to the receivable. Here, and throughout this annual report, when we refer to property, we mean, with respect to any person, any interest of that person in any kind of property or asset, whether
real, personal or mixed, or tangible or intangible, including, without limitation, capital stock in any other person. For a more complete explanation of what we mean when we say lien, see Description of Principal
AgreementsThe Fiscal Agency AgreementCovenantsNegative Pledge;

(c) all guarantees, insurance,
letters of credit and other agreements or arrangements that support or secure payment of the receivable, whether or not included in the contract giving rise to the receivable; and

(d) any rights or remedies arising under the contract giving rise to the receivable, including in the case of (b), (c) and
(d) obligations evidenced by an account, note, instrument, contract, security agreement, chattel paper, general intangible or other evidence of indebtedness or security; and



| |  |  | all associated collections. For a more complete description of collections, see Description of Principal AgreementsThe Servicing and Collection Agency
Agreement.

An eligible receivable is a receivable with the following characteristics:



| |  |  | the final invoice on the receivable must be delivered to the customer no later than two days before the receivable is due and payable;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | upon delivery of the final invoice the receivable is an obligation to pay a precise sum;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | the receivable is not subject to a credit memorandum or any other setoff, reduction, dispute or other form of negative adjustment; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

| |  |  | the receivable is required to be paid in full no later than 30 days after the date of the bill of lading for the appropriate shipment, whether or not the receivable is actually paid
during that period. The period may be increased to up to 90 days if that becomes the prevailing practice in the international oil business.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Receivables that will be generated in the future must meet the same criteria to become eligible receivables.

When we use the term purchased receivable in this annual report, we mean the eligible receivables of designated customers that we have purchased from PMI Services and that PMI Services has purchased from PMI under the
receivables purchase agreement. However, any purchased receivable that we return to PMI Services under the relevant provisions of the receivables purchase agreement is no longer a purchased receivable. See Description of Principal
AgreementsThe Receivables Purchase AgreementSubstitution and Repurchase of Receivables. To qualify as an eligible receivable for purposes of the definition of a purchased receivable, a receivable must meet the specifications listed
above and relate to a customer that was an eligible customer as of the date on which the receivable was generated or on which it was purchased, whichever comes later.

For purposes of the covenant on the availability of eligible receivables of designated customers, the relevant receivable must relate to a customer that, on the day the receivable was generated, was an eligible
customer. See Description of Principal AgreementsThe Receivables Purchase AgreementCovenants.

Under the
receivables purchase agreement, on our instruction, PMI Services pays the purchase price for eligible receivables into an account designated by PMI. With this payment, PMI Services purchases from PMI previously generated eligible receivables of
designated customers and, when there are no previously generated eligible receivables at that time, future eligible receivables. PMI Services purchases the eligible receivables in the order in which they are generated. In turn, we purchase the same
eligible receivables from PMI Services on the same day that it purchases those receivables from PMI by depositing the purchase price into an account designated by PMI Services.

PEMEXs Customers and Receivables

Except as otherwise indicated, all figures given in this
section regarding percentage of total exports and market share are based on volumes of crude oil and not on sales revenue. All 2005 export figures are based on preliminary figures which may be adjusted when the export sales are finalized.

Overview

Since
its incorporation in 1989, PMI has marketed approximately 99% of PEMEXs crude oil exports. As of May 31, 2006, Petróleos Mexicanos owns 98.3% of PMIs stock while 1.7% is owned by Banco Nacional de Comercio Exterior, S.N.C.,
which is in turn 99% owned, directly or indirectly, by the Mexican Government. The Ministry of Energy also owns 0.0002% of PMIs stock. In the receivables purchase agreement, PEP has agreed to continue to export through PMI at least 90% of its
total exports of crude oil.

Here, and throughout this annual report, the term export should be understood to mean any sale or
shipment of crude oil from Mexico to a point outside Mexico, excluding any shipment (1) for the purposes of storage by or on behalf of Petróleos Mexicanos or its Affiliates or (2) for processing and return to Mexico.

During 2005, PMI exported an average of 1,817.1 tbpd of crude oil, or 54.5% of PEPs crude oil total production; the remainder was used
domestically. During 2004, PMI exported 55.3% of PEPs crude oil production and during 2003 it exported 55% of PEPs crude oil production. Of PMIs crude oil exports during 2005 by volume, approximately:



| |  |  | 78.6% were to the United States,
| | - |  | --------------------------------



| |  |  | 8.9% were to Spain,
| | - |  | -------------------

| |  |  | 2.0% were to Canada, and
| | - |  | ------------------------



| |  |  | 5.4% were to others.
| | - |  | --------------------

Exports of Maya crude oil during
2005 were an average of 1,505.6 tbpd and accounted for 83% of PMIs total exports of crude oil. During 2005, PMI exported an average of 1,319 tbpd of Maya crude oil to its designated customers of which:



| |  |  | 1,203.71 tbpd were exported to the United States designated customers,
| | - |  | ----------------------------------------------------------------------



| |  |  | 24.38 tbpd were exported to the Canadian designated customers, and
| | - |  | ------------------------------------------------------------------



| |  |  | 91.13 tbpd were exported to the Aruban designated customers.
| | - |  | ------------------------------------------------------------

PMIs exports of Maya crude oil to the designated customers during 2005 accounted for 100% of PMIs total Maya crude oil exports to customers in the United States, Canada, and Aruba and 86.77% of PMIs total Maya crude oil
exports worldwide. Maya crude oil exports to non-designated customers outside the U.S., Canada and Aruba (excluding PMI NASA) accounted for 13.23% of PMIs total exports of crude oil. Of total Maya crude oil exports not sold to United States,
Canadian or Aruban customers (which include PMI NASA), an average of 165 tbpd were sold to Europe, 32 tbpd to the Far East, 3 tbpd to Central America and South America and 1 tbpd to Africa.

During 2005, PMI exported to PMI NASA, Petróleos Mexicanos Mexican affiliate, approximately 2.8% of its total Maya crude oil exports under a
long-term contract.

On sales made from January 1, 1993 through May 31, 2006 PMI did not record any losses for unpaid receivables
relating to purchases of Maya crude oil by the designated customers. Historically, approximately 98% of PMIs customers have paid by the payment due date in accordance with the credit terms established in their sales contract.

PMI makes a significant percentage of its Maya crude oil sales to designated customers under (i) evergreen contracts, which typically allow the
parties to terminate the agreement with three months notice, and (ii) long-term contracts. PMI exports most of the remaining quantity to the same customers pursuant to separate supply contracts under economic terms, with respect to each
customer, equivalent to those set forth in the evergreen contracts with such customer. In 2005, PMI sold approximately 55% of its total Maya crude oil exports under evergreen contracts for specified volumes to third parties and 45% of its total Maya
crude oil exports under long-term contracts for specified volumes to third parties. In 2004, PMI sold approximately 90% of its total Maya crude oil exports under evergreen and long-term contracts for specified volumes to third parties.

PMI focuses its marketing effort on strengthening customer relationships and bases its marketing strategy on maintaining long-term commercial
relationships and customer loyalty. In fact, most of PMIs crude oil customers are long-standing customers that have had relationships with PEMEX for 15 to 20 years.

A majority of PMIs crude oil customers receive shipments on a regular basis. As a result, there is little seasonality in PMIs sales volumes of crude oil. Crude oil customers are invoiced through a pricing
formulas set forth in the applicable contract. Generally, PMI bases these formulas on market prices and standard payment terms of 30 days after generation of the bill of lading.

PMIs Credit Department evaluates the creditworthiness of each potential customer. Based on an evaluation of the customers financial position,
estimated business potential and current market conditions, the Credit Department recommends a specific credit limit and terms and conditions, including whether the customer should be required to provide advanced payment or a letter of credit issued
by a qualified bank. PMI has a comprehensive program to monitor outstanding receivables.

Crude oils can also be classified by their amount of sulfur content by weight. Sour crudes contain 3.4% or greater sulfur content by weight and sweet crudes contain less than 1.0% sulfur
content by weight. Substantially all of PMIs exports are classified as sour crude.

Geographic Distribution of Exports

In 2005, 98% of PMIs exports were to countries in the Western Hemisphere. The balance was exported to other countries. The
designated customers, which purchased Maya crude oil from PMI in 2005 and/or in 2006 through May 31, are located in four countries. Customers in the United States, Spain and Netherlands Antilles have consistently been PEMEXs largest
customers. During 2005, crude oil exports were distributed as follows:

PMIs Delinquency and Loss Experience

PMI did not incur any losses for unpaid receivables on its sales made from January 1, 1993 through December 31, 2005. As of December 31,
2005, PMI was not required to record on its books provisions for losses on accounts receivable corresponding to export sales of crude oil. However, PMIs loss and delinquency experience for receivables, including purchased receivables sold to
us under the receivables purchase agreement, in the future may be different than PMIs historical experience.

##### Table of Contents

As of December 31 for each year from 1996 to 2000, PMI had no past due receivables, compared to past
due receivables of U.S.$19.9 million as of December 31, 1995. As of December 31 for each year from 2002 to 2005, PMI had no past due receivables, compared to past due receivables of U.S.$13.57 million as of December 31, 2001,
which was paid in full on January 2, 2002. The following table sets forth the maximum number of days of past due accounts during the years indicated.

|2005 |  | 5                                         

PMIs customers subsequently paid all the past due receivables at these dates in full, with
interest.

Average Delinquencies

Approximately 99% of PMIs customers pay on the payment due date in accordance with the credit terms established in their respective sales contracts, and the remainder pay within 30 days thereafter. PMIs
low rate of payment delinquencies is attributable to:



| |  |  | the high credit quality of its portfolio of customers,
| | - |  | ------------------------------------------------------



| |  |  | PMIs contract terms and conservative credit policies, and
| | - |  | ----------------------------------------------------------



| |  |  | the relatively high interest rate and administrative charges (Prime rate plus 6%, not compounded) which PMI charges as a penalty on delinquent payments.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------

The majority of untimely payment delinquencies which PMI has experienced are a result of administrative problems which are settled within seven days.
Historically, PMIs customers have paid the invoice amounts in full regardless of disputes related to price and claims of quality and quantity. These disputes are settled through credit and debit notes.

PMIs management is unaware of any trend that would change its portfolio performance.

Credit and Collection Policies

Credit Approval Process

All of PMIs customers pay in one of three manners:



| |  |  | from an open account,
| | - |  | ---------------------



| |  |  | through a letter of credit, or
| | - |  | ------------------------------



| |  |  | with advance payments.

##### Table of Contents

During 2005, 6.73% of PMIs export sales of crude oil were backed by letters of credit. The
remainder was paid from open accounts. The manner in which each customer pays for the crude oil it purchases reflects PMIs assessment of the credit risk that customer presents. PMIs financial area carries out the evaluation and
monitoring of the creditworthiness of each customer, and the assessment of the manner in which it should pay. Under the agreements governing Pemex Finances operations and purchase of receivables, PMI agreed to apply its credit and collection
policies to all of the designated customers, including the affiliated designated customer. The financial area receives information from different sources, including audited financial records, commercial and banking references and external credit
reports prepared by credit and rating agencies. This assessment, which involves financial analysis, focuses primarily on the customers capacity to generate cash flow and its prior credit history. The financial area compares the clients
financial structure, liquidity, cash flow and profitability ratios with the industry and regional market in which the company operates. PMI also considers country and sovereign risk in the analysis. Based on this information, PMIs financial
area issues an opinion to the credit committee on the creditworthiness of the future customer.

The PMI credit committee is responsible for
evaluating certain types of credits. More specifically, credit committee approval is required for:



| |  |  | granting a client the right to pay through the open account method;
| | - |  | -------------------------------------------------------------------



| |  |  | deciding to require a client who currently pays through an open account to use another alternative;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | increasing line of credit limits;
| | - |  | ---------------------------------



| |  |  | accepting new clients without an investment grade rating assigned by Standard & Poors or Moodys; and
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | canceling existing lines of credit.
| | - |  | -----------------------------------

All other cases are
subject to assessment and action by the financial area, which reports its recommendations and actions to the credit committee. The credit committee meets at least once a month. Its members include PMIs directors and finance manager. At least
once a year the financial area will reevaluate its recommendations regarding each credit line. All lines of credit are submitted to the credit committee for renewal at maturity. If a customer has not purchased from PMI during the prior two years,
its line of credit will not be renewed until it is needed.

The financial area takes primary responsibility for monitoring PMIs
credit exposure on a daily basis. The financial area is a subdivision of the finance department, which is composed of the finance manager, the accounting manager, the risk management department, the systems manager and the treasurer.

Contract Terms and Conditions

PMI
makes a significant percentage of its crude oil sales under evergreen contracts, which typically allow the parties to terminate the agreement with three months notice, and long-term contracts. PMI exports most of the remaining quantity to the same
customers that purchase under evergreen contracts but under separate supply contracts, applying the pricing formula included in the evergreen contracts. PMIs export sales of crude oil are conducted on a free-on-board (FOB) basis.
In practically all cases, title to the crude oil passes to the customer upon the crudes loading on the ship. The invoice prepared by PMIs treasury department states the final price for the quantity delivered. PMI generally prepares the
invoice within five days of the delivery of crude oil, and presents it to the customer immediately by fax or telex transmission. The full amount of the invoice is due within the term established by the contract for such customer, which is generally
30 days from the day the bill of lading is generated. The bill of lading is generated when the crude oil is loaded onto the ship. PMI typically imposes interest on a daily basis equivalent to an annual rate of Prime rate plus 6%, not compounded, for
all past due accounts. PMI may provide discounts or rebates for advance payments of any amount due.

Sales prices for Mexican crude oil are
based on formulas which vary for each type of crude oil and for each geographic region in which specific crude oil is sold. These formulas consider international market quotations for

##### Table of Contents

one or more benchmark crude oil or products and a constant set by PEMEXs pricing committee (which consists of representatives from the Ministry of
Energy, the Ministry of Finance and Public Credit, the Ministry of Economy, the General Comptrollers Office, Banco de México and PEMEX). The pricing formulas differ by consuming regions and the type of crude oil.

Monitoring of Existing Accounts

PMI
has a comprehensive program for monitoring its outstanding receivables. Senior management in the commercial and finance areas is notified of any overdue payments by a customer on a daily basis, and may suspend future sales to that customer or cancel
its credit unless the customer promptly pays its overdue invoices. The credit department also monitors the creditworthiness of existing customers, including affiliated customers, adjusting the terms of sale to reflect changes in each customers
creditworthiness.

Marketing

PMI focuses its marketing effort on strengthening customer relationships by analyzing and understanding specific purchasing patterns, closely monitoring market conditions and reacting promptly to price variations. Its marketing strategy is
based on maintaining long-term commercial relationships and customer loyalty. In fact, most of PMIs crude oil customers are long-standing customers that have had relationships with PMI or, prior to PMIs incorporation in 1989,
Petróleos Mexicanos for an average of 15 to 20 years.

In 2005, all of PMIs crude oil export sales to customers qualifying as
designated customers were made pursuant to PMIs general terms and conditions to customers with which it maintains long-standing commercial relationships. In 2005, all of the invoices for crude oil export sales were paid within the established
credit terms. PMI has a policy of not selling crude oil on the spot market. PMI has a policy under which it only sells its crude oil to customers that own or operate refineries.

Sales to Affiliates. PMI NASA is PMIs only current customer which both qualifies as a designated customer and is an Affiliate of
Petróleos Mexicanos. It has entered into a long-term supply contract with PMI which requires the supply of minimum quantities of crude oil and other feed stocks under an evergreen contract, which has a three month phase-out clause. PMI
exported 42 tbpd crude oil to PMI NASA during 2005.

Sales to Third Parties. PMIs sales to third parties for exports of crude
oil, including sales to the designated customers with which it maintains long-standing commercial relationships, are made at market prices pursuant to PMIs general terms and conditions. Among its customers are most of the major oil companies
and other large private companies. Sales under PMIs general terms and conditions are priced in U.S. dollars.

DESCRIPTION OF
PRINCIPAL AGREEMENTS

We have entered into several agreements which govern the purchase, sale and collection of the receivables
described in this annual report. The first, the receivables purchase agreement, is among PMI Services, PMI, PEP and Pemex Finance. Its main purpose is to specify the terms by which PMI Services buys receivables from PMI and we buy receivables from
PMI Services. The second agreement is the fiscal and paying agency agreement we entered into with The Chase Manhattan Bank (now JPMorgan Chase Bank, N.A.), as fiscal and paying agent, and Chase Manhattan Bank Luxembourg, S.A. (now J.P. Morgan Bank
Luxembourg S.A.), as paying agent. The fiscal agency agreement establishes many of the important covenants and events of default with which we must comply. It also governs the fiscal agents role as our principal paying agent for the payment of
principal, interest and premium, if any, in respect of our Indebtedness, including the Notes.

The third agreement is the servicing and
collection agency agreement, and is among Pemex Finance, PMI, PMI Services, Petróleos Mexicanos as investment manager and UBS AG as the initial collection agent. Standard

##### Table of Contents

Chartered Bank replaced UBS AG as collection agent in October 1999. This agreement sets forth the procedures for the servicing, managing and collection of
the receivables that have been sold by PMI to PMI Services and thereafter to us. Finally, the fourth agreement is the letter agreement between Petróleos Mexicanos and Pemex Finance. In this agreement, Petróleos Mexicanos agrees to
cause PEP, PMI and PMI Services to comply with their material obligations under the receivables purchase agreement and the crude oil sale agreement governing the sale of crude oil from PEP to PMI.

All four of these agreements are dated as of December 1, 1998; the receivables purchase agreement and the fiscal agency agreement were each amended
as of February 10, 2000.

The following is a summary of the material provisions of these principal agreements, as amended. Each of the
above-mentioned agreements is included as an exhibit to this annual report. These exhibits are incorporated in this annual report by reference to the registration statement of Pemex Finance and Petróleos Mexicanos on Form F-4 dated
September 30, 1999 (registration statement no. 333-10920) and, in the case of the amendments to the receivables purchase agreement and the fiscal agency agreement, to the registration statement of Pemex Finance and Petróleos Mexicanos on
Form F-4 dated September 27, 2000 (registration statement no. 333-12614).

Copies of these agreements are also available for
inspection at the principal office of the fiscal agent in the City of New York, which is presently located at JPMorgan Chase Bank, N.A., Capital Markets Fiduciary Services, 4 New York Plaza, 15thFloor, New York, NY 10004.

entitled Glossary of Certain Defined Terms Used Primarily Under the Captions Description of the Principal Agreements and Description of the Indenture for definitions of capitalized terms that appear in this annual
report.

The Receivables Purchase Agreement

We and PMI Services purchase eligible receivables under the receivables purchase agreement. More specifically, under the receivables purchase agreement, subject to payment of the purchase price:



| |  |  | PMI Services has the right to purchase, upon our request and in the amount we specify, eligible receivables of designated customers from PMI;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PMI sells to PMI Services all its present and future right, title and interest in, to and under eligible receivables of designated customers that have been generated and will be
generated by PMI, without recourse (except as specified under Substitution and Repurchase of Receivables below);
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we have the right to purchase eligible receivables of designated customers from PMI Services; and
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | PMI Services sells to us all its present and future right, title and interest in, to and under eligible receivables of designated customers generated and to be generated by PMI,
without recourse (except as specified under Substitution and Repurchase of Receivables below).
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We and PMI
Services purchase the eligible receivables in the order in which they are or will be generated. Thus, we acquire title not only to some of the current eligible receivables of designated customers, but also to some of their future receivables. A
receivable is considered generated at the moment a customer becomes obligated to pay PMI for crude oil. The obligation to pay is the receivable.

The purchase price that we and PMI Services pay for each receivable is determined by discounting the face value of the purchased receivable by the number of days between the date the receivable was purchased and the
day on which it is due and payable at a discount rate. The discount rate is equal to the weighted average of the yield of our outstanding Indebtedness on the date on which the purchased receivable is sold to us plus 50 basis points. This
discount at which eligible receivables are purchased will be adjusted upward in some limited circumstances to reflect a change in the delinquencies, if any, of the designated customers.

In the ordinary course, we will buy receivables which are generated by the sale of Maya crude oil.
However, we consider any date on which the monthly average amount of PMIs exports of Maya crude oil to designated customers outside of Mexico for the six months prior to that date is less than 450 tbpd to be a Maya shortfall
day under the receivables purchase agreement. On any Maya shortfall day, PMI will be obligated to sell to PMI Services and PMI Services will be obligated to sell to us all its present and future rights, title and interest in existing and
future eligible receivables of designated customers generated or to be generated in connection with the export of crude oil other than Maya crude oil, including those receivables existing at the close of business on the Maya shortfall day. In
addition, we, PMI Services and PMI from time to time may agree to the purchase and sale of existing and future receivables generated or to be generated from the shipment of crude oil other than Maya.

In addition, PMI agrees that any person who is a United States or Canadian person who enters into a long term contract for the purchase of Maya crude oil
shall be made a designated customer within 60 days of entering into that contract.

Representations and Warranties

PMI makes some representations and warranties on each date on which we or PMI Services purchase eligible receivables, including
that:



| |  |  | each designated customer has executed a designated customer notice acknowledging that it has received notice that it should make payments on the purchased receivables into the
collection account described in The Servicing and Collection Agency Agreement;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | each purchased receivable and designated customer notice of a designated customer is the legal, valid and binding obligation of that designated customer;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | upon completion of any sale of eligible receivables to us under the receivables purchase agreement and attachment of our ownership interest in those receivables, we will have a
perfected ownership interest in those purchased receivables;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | each purchased receivable has been generated in compliance with applicable law; and
| | - |  | -----------------------------------------------------------------------------------



| |  |  | PMI Services will have all of PMIs right, title and interest in the purchased receivables free and clear of any lien attributable to PMI.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------

In addition, PMI Services represents that on each date on which it sells us eligible receivables we will have all right, title and interest of PMI
Services in the purchased receivables free and clear of any lien attributable to PMI Services.

Covenants

We, PEP, PMI and PMI Services have made a number of covenants under the receivables purchase agreement, some of which are described below.

PEP has agreed that it will not export crude oil, directly or indirectly, to any designated customer other than through PMI. Further, PEP has agreed that
it will export at least 90% of its total exports of crude oil through PMI. Compliance with this agreement is tested by looking at 90 day periods. However, if (1) PMI ceases to be an Affiliate of Petróleos Mexicanos or PEP or (2) PMI
becomes bankrupt or insolvent, PEP has agreed that it shall instead export at least 90% of its total crude oil exports through PMI Services.

PMI Services has also agreed that:



| |  |  | it will use the proceeds of any sale of eligible receivables to us to purchase eligible receivables from PMI;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | it will not incur any lien, directly or indirectly (other than certain permitted liens, as described in The Fiscal Agency AgreementCovenantsNegative
Pledge) on or with respect to any of its property to secure any Indebtedness; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | it will not (1) engage in any business other than the acquisition and sale of eligible receivables, the other transactions contemplated by the transaction documents, and any
activity incidental, necessary or convenient to accomplish those transactions, or (2) enter into or be a party to any other agreement or instrument, except that PMI Services may borrow funds on a subordinated basis from any of its Affiliates in
accordance with the transaction documents.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Finally, PMI has agreed:



| |  |  | upon generation of any eligible receivable of designated customers for which the purchase price has been paid to PMI, promptly to identify, or cause the servicer to identify, this
receivable as sold to PMI Services and subsequently to us;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to keep as shall be reasonable appropriate records, maintain and implement adequate administrative and operating procedures and permit our representatives to examine the
documentation relating to the generation, sale, administration and collection of purchased receivables;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | with some exceptions, to cause the monthly average amount of eligible receivables of designated customers that are generated by PMI during any consecutive twelve month period and
that are not subject to any encumbrance other than as provided under the receivables purchase agreement to represent at least the lesser of:
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 20 million barrels of Maya crude oil; and
| | - |  | -----------------------------------------



| |  |  | 80% of PMIs total eligible receivables generated from sales of Maya crude oil;
| | - |  | -------------------------------------------------------------------------------



| |  |  | to add one or more new designated customers in the event that the monthly average amount of PMIs exports of Maya crude oil to customers which are not designated customers
incorporated in the United States, Canada or Aruba exceeds 40% of PMIs total exports of Maya crude oil during any consecutive six month period. If PMI is required by this covenant to add designated customers, it shall add sufficient new
customers so that, if the new designated customers had been designated customers throughout the six month period, the monthly average amount of exports of Maya crude oil to all designated customers during the six month period would have been at
least 70% of PMIs total exports of Maya crude oil during the period. PMI shall add these new designated customers from countries which are members of the Organization for Economic Cooperation and Development first and from other countries
second;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to add one or more new designated customers in the event that the monthly average amount of PMIs exports of Maya crude oil to customers who are neither designated customers
nor end users exceeds 20% of PMIs total exports of Maya crude oil during any consecutive three month period. An end user is a customer of PMI who purchases crude oil from PMI for its own use and not for resale. PMI shall add new designated
customers until the monthly average amount of export sales to designated customers who are both designated customers and end users during the three month period plus the exports to new customers would have been no less than 70% of PMIs total
exports of Maya crude oil;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | not to amend the designated customer notices without the prior written consent of Petróleos Mexicanos and the fiscal agent, in accordance with the transaction documents;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to maintain in effect the servicing and collection agency agreement;
| | - |  | --------------------------------------------------------------------



| |  |  | to preserve and maintain its corporate existence;
| | - |  | -------------------------------------------------



| |  |  | to conduct all business transactions with PEP, PMI Services and us on an arms length basis according to industry standards;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | to take all further action, reasonably necessary and requested by us, to protect or more fully evidence our right, title and interest in the purchased receivables at its expense;

| |  |  | not to extend, make any adjustment to, rescind, cancel, amend or otherwise modify, or attempt or purport to extend, make any adjustment to, rescind, cancel, amend or otherwise

of Section 9-402(7) of the Uniform Commercial Code, or impair the perfection of our interest in any purchased receivable without prior written notice to us;

| |  |  | not to prepare any financial statements which shall account for the transactions contemplated under the receivables purchase agreement in any manner other than as purchases or sales
of the purchased receivables originated by PMI, except in connection with the preparation of financial statements for tax or tax accounting purposes in accordance with applicable laws;

or the United States as may be required in connection with the transactions contemplated in the receivables purchase agreement; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to conduct its sales to designated customers that are directly or indirectly Controlled by Petróleos Mexicanos in a manner consistent with its application of its collection
policies to designated customers that are not Affiliates of Petróleos Mexicanos.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Substitution and Repurchase of
Receivables

In most cases, PMI shall not have any:



| |  |  | right, title or interest in or to the purchased receivables;
| | - |  | ------------------------------------------------------------



| |  |  | obligation to repurchase the purchased receivables; or
| | - |  | ------------------------------------------------------



| |  |  | right or obligation to substitute other receivables for the purchased receivables.
| | - |  | ----------------------------------------------------------------------------------

However, PMI may elect to repurchase, directly or indirectly, receivables it sold to us at any time under the following circumstances:



| |  |  | when a representation or warranty made with respect to that purchased receivable in the receivables purchase agreement was inaccurate at the time that the representation or warranty
was made;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | when the designated customer owing payment on that purchased receivable was not an eligible customer as of the date that the receivable was generated or, if it was generated prior
to our purchase of it, the date it was purchased; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | when that purchased receivable was not an eligible receivable as of the date it was generated or, if it was generated prior to our purchase of it, the date it was purchased.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If PMI elects to repurchase any purchased receivable affected by any of these three factors, it shall do so at a repurchase
price equal to the purchase price we originally paid for that receivable plus a repurchase adjustment. This adjustment shall be calculated in the following way:



| |  |  | the amount billed by PMI to the customer on account of the crude oil lifted by or delivered to that customer, minus any setoff, dispute, reduction or negative adjustment, shall be
multiplied by
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the discount rate applicable to that receivable, as described above in the introduction to this description of the receivables purchase agreement, multiplied by
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a fraction, (a) the numerator of which is the number of days from, and including, the later of the purchase date and the date of generation of that receivable, up to, but
excluding, the date PMI Services deposits this repurchase price into the collection account, and (b) the denominator of which is 360.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

Moreover, the sale of a purchased receivable will be rescinded if at any time PMI:



| |  |  | becomes aware that a receivable which has been affected by any of the three factors which would allow PMI to elect to repurchase that receivable has not been paid within five
business days after it became due;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | becomes aware that that a purchased receivable has become subject to a credit memorandum, or any other set-off, dispute, reduction or other form of negative adjustment; or
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | receives written notice from us or on our behalf that we cease to have a perfected first priority ownership interest in any purchased receivable.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------

Upon becoming aware of a failure by PMI, PMI Services or PEP to comply with certain covenants, we may give notice of that failure to PMI and PMI
Services. Upon receipt of that notice, we may elect to rescind prior sales of purchased receivables sold to us prior to that date for which no collections have been received by the collection agent. However, we may not elect to rescind prior sales
of purchased receivables which have become delinquent, meaning not paid within five business days of becoming due.

If a sale is rescinded,
we shall return the relevant purchased receivable to PMI Services, and PMI Services shall return that purchased receivable to PMI. In return, PMI Services will deposit in the collection account an amount calculated in the same manner that the
repurchase price was calculated, as described above. Immediately upon such deposit by PMI Services, PMI will pay PMI Services an equal amount and PMI Services shall return to PMI the receivables that we returned to PMI Services. The rescission will
not be effective until the repurchase price has been deposited in the collection account.

Replacement: Circumstances in Which PMI
Services or PMI Will Assume the Others Obligations

PEP shall be required to export crude oil through PMI Services instead of
PMI in the event that:



| |  |  | a bankruptcy or insolvency event of PMI occurs; or
| | - |  | --------------------------------------------------



| |  |  | PMI ceases to be an Affiliate of Petróleos Mexicanos or PEP.
| | - |  | ------------------------------------------------------------

In connection with the issuance of the February 1999 Notes, the parties to the receivables purchase agreement and Petróleos Mexicanos entered into a supplemental agreement. Under this supplemental agreement, if
specified events related to bankruptcy, merger or sale of the assets of PMI Services occur, PMI will agree to perform the material obligations of PMI Services set forth in the receivables purchase agreement, the servicing and collection agency
agreement, the letter agreement and each designated customer notice. Further, if a PMI bankruptcy or insolvency event occurs or if PMI ceases to be an Affiliate of Petróleos Mexicanos or PEP, PEP will agree to perform the material obligations
of PMI Services set forth in those agreements. In other words, under these circumstances, PMI will sell receivables directly to us.

Assignment

Neither PMI nor PMI Services may assign its obligations under the receivables purchase agreement other
than:



| |  |  | to Petróleos Mexicanos or its successor or an Affiliate of Petróleos Mexicanos or its successor; or
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | in connection with a transaction in which PEP shall sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its oil producing assets to an entity
which assumes all of the obligations of PEP under the receivables purchase agreement, the servicing and collection agency agreement, the letter agreement and each designated customer notice. Unless the entity to which PEP seeks to transfer its
obligations is (a) Petróleos Mexicanos or its successor or (b) an Affiliate controlled, directly or indirectly, by Petróleos Mexicanos or its successor the assignment would not be allowed if it would give rise to a Rating
Decline.

In both exceptions, the assignee of PMI Services must be an entity which, in the case of a bankruptcy or
insolvency event of PMI, will not be treated as part of the bankrupt estate of PMI. In addition, in each case (A) the assignee must expressly assume all the obligations of PEP, PMI Services or PMI, as the case may be, under the receivables
purchase agreement and (B) the following documents must be delivered to us prior to the assumption:

(1) (a) opinions
of counsel to the assignee with respect to the laws of New York, Mexico and the jurisdiction where the assignee is located stating that:



| |  |  | the receivables purchase agreement is a valid, binding and enforceable obligation of the assignee;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | the receivables purchase agreement is in the proper form to, and the execution and delivery of it and our payment of the purchase price for the purchased receivables constitutes all
action required to, convey to us all of the assignees right, title and interest in the purchased receivables; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | all action has been taken to permit our interest in the purchased receivables to be perfected upon attachment;
| | - |  | --------------------------------------------------------------------------------------------------------------

(b) an opinion of New York counsel to the assignee stating that the designated customer notices are valid and binding obligations of, and
enforceable against, the designated customers under New York law;

(c) an opinion of counsel, which counsel will be
reasonably acceptable to us, stating that the assignment will not create a deemed taxable exchange of the notes for United States federal income tax purposes; and

the counsel must be reasonably acceptable to us, and the opinions will be subject to assumptions and qualifications which are customary in this type of opinion;

(2) copies of designated customer notices executed and delivered by the assignee and acknowledged by each of the designated customers.

Substitution to Mitigate Taxes

The rights and obligations of PMI or PMI Services may be assigned to another entity that assumes those rights and obligations without the consent of the fiscal agent for several reasons related to taxation. Namely,
this assignment may be made to mitigate any increase in taxes payable by PMI with respect to the transactions contemplated by the receivables purchase agreement as a consequence of (1) a change in tax laws or regulations in Mexico or
(2) any change in the application or official interpretation of those laws or regulations. PMI or PMI Services can only assign its rights and obligation under these circumstances if, after giving effect to the assignment and assumption, the
following conditions are fulfilled:



| | (1) | the affirmation by each rating agency that is then rating our notes of the rating it is giving the notes;
| | --- | ---------------------------------------------------------------------------------------------------------



| | (2) | the satisfaction of the requirements regarding opinions of counsel and designated customer notices described in clauses (1) and (2) above in Assignment;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| | (3) | no event of default or event that with the passage of time or the giving of notice would constitute an event of default or specified event under the fiscal agency agreement, as
described in  The Fiscal Agency AgreementEvents of Default and Specified Events, shall have occurred and be continuing;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (4) | any insurance, guaranty or other suretyship arrangement regarding any notes to which we have previously consented in writing shall be in full force and effect;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (5) | the satisfaction of any steps required under Mexican law; and
| | --- | -------------------------------------------------------------



| | (6) | the receipt of an opinion of Mexican counsel, which counsel must be reasonably acceptable to Pemex Finance, stating that the assignment does not materially impair the
characterization of the transactions contemplated by the receivables purchase agreement.

Perfection of Pemex Finances and PMI Services Ownership or Security Interest in the
Purchased Receivables

No law in Mexico, The Netherlands or the Cayman Islands requires filing or recording with any governmental
office for the establishment, preservation, protection, perfection or priority of an ownership or security interest in purchased receivables, whereas New York law requires the filing of appropriate UCC financing statements in the jurisdiction in
which PMI and PMI Services, as sellers, are located. PMI and PMI Services would be considered located in the District of Columbia for this purpose. Under the foregoing laws, no further act will be required to establish, preserve, protect, perfect or
establish the priority of, our or PMI Services ownership interest or security interest in the purchased receivables upon:



| |  |  | the completion of any sale of eligible receivables by PMI to PMI Services and by PMI Services to us in accordance with the receivables purchase agreement,
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the delivery of notice to the designated customers and the receipt by PMI of a duly executed and completed acknowledgment of that notice,
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the satisfaction of some Mexican law formalities, and
| | - |  | -----------------------------------------------------



| |  |  | the filing of UCC financing statements with the appropriate filing office in respect of the sale of eligible receivables by PMI to PMI Services and by PMI Services to us.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Governing Law, Jurisdiction and Waiver of Immunity

The receivables purchase agreement is governed by and interpreted in accordance with the laws of the State of New York with the following exceptions:



| |  |  | the laws of Mexico govern the authorization and execution of the agreement by PEP and PMI and all sales of receivables under the receivables purchase agreement,
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the laws of The Netherlands govern the authorization and execution of the agreement by PMI Services, and
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | the laws of the Cayman Islands govern our authorization and execution of the agreement.
| | - |  | ---------------------------------------------------------------------------------------

We and PEP have appointed the Consul General of Mexico in New York City and his successors as our process agent. PMI and PMI Services have appointed Curtis, Mallet-Prevost, Colt and Mosle acting through their offices
in New York as their process agent. This means that process may be served on these agents in any action based upon the receivables purchase agreement which may be instituted in the Supreme Court of the State of New York, County of New York, any
federal court sitting in the Borough of Manhattan, The City of New York and any appellate court or body thereto. We, PEP, PMI and PMI Services have each:



| |  |  | irrevocably submitted to the jurisdiction of any such court in respect of any such action;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | irrevocably waived, to the fullest extent permitted by law, any objection which we may have now or later to the laying of venue of any such action in any such court; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | waived any right to which we may be entitled on account of residence or domicile.
| | - |  | ---------------------------------------------------------------------------------

PEP and PMI have reserved the right to plead sovereign immunity under the United States Foreign Sovereign Immunities Act of 1976 with respect to actions brought against either of them under United States federal
securities laws or any state securities laws. Further, PEPs and PMIs appointment of the applicable process agent as its agent for service of process will not extend to these actions. In the absence of this waiver of immunity by PEP, it
would not be possible to obtain a judgment in an action brought in a United States court against PEP, unless such court were to determine that PEP is not entitled under the Immunities Act to sovereign immunity with respect to that action. The same
is true of PMI. Even if a United States judgment could be obtained in any action under the Immunities Act, it may not be possible to obtain in Mexico a judgment based on such a United States judgment. Moreover, execution upon property that PEP or
PMI may have in the United States to enforce a judgment obtained under the Immunities Act may not be possible except under the limited circumstances specified in the Immunities Act.

Articles 1, 2, 3, 4 (and other related articles) of the Organic Law of Petróleos Mexicanos and Subsidiary Entities and Article 4 of the Federal Code of Civil Procedures of Mexico establish, among other things, that:



| |  |  | attachment prior to judgment, attachment in aid of execution and execution of a final judgment may not be ordered by Mexican courts against property of Petróleos Mexicanos
and some of the subsidiary entities;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | all domestic petroleum and hydrocarbon resources (whether solid, liquid or gas form) are directly, permanently and inalienably vested in Mexico (and, to that extent, subject to
immunity);
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | (a) the exploration, exploitation, refining, transportation, storage, distribution and first-hand sale of crude oil, (b) the exploration, exploitation, production and
first-hand sale of natural gas, as well as the transportation and storage inextricably linked with that exploitation and production, and (c) the production, storage, transportation, distribution and first-hand sale of the derivatives of
petroleum (including petroleum products) and natural gas that are susceptible of being used as basic industrial raw materials and that constitute basic petrochemicals (the petroleum industry) are reserved exclusively to
Mexico (and, to that extent, assets related thereto are entitled to immunity); and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the public entities created and appointed by the Federal Congress of Mexico to conduct, control, develop and operate the petroleum industry of Mexico include Petróleos
Mexicanos and PEP. Therefore, Petróleos Mexicanos and PEP are entitled to immunity in respect to such exclusive rights and power.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result, notwithstanding PEPs waiver of immunity described in the preceding paragraph, a Mexican court may not enforce a judgment against PEP by ordering the attachment of its assets.

Termination

The receivables
purchase agreement may be terminated by the parties at any time 90 days after notification by the fiscal agent that we have satisfied and discharged all of our obligations under any of our Indebtedness and that Indebtedness has ceased to be of
further effect.

Limitation on Contract Liability



| |  |  | None of Mexico, Petróleos Mexicanos, PMI, PMI Services and Pemex Finance, or any of their Subsidiaries or Affiliates in any way guarantees or is liable for payment by any
designated customer of the purchased receivables;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | none of Petróleos Mexicanos, its Subsidiaries, including PEP, or any of its Affiliates is obligated under the receivables purchase agreement to produce or export oil; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | none of the fiscal agent, the trustee, the collection agent, or any holder of our Indebtedness has any ownership interest or security interest in Mexicos crude oil, whether in
the ground or extracted.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Fiscal Agency Agreement

Covenants

We have made a number of covenants under the fiscal agency agreement for the
benefit of the holders of all our Indebtedness. We must comply with these covenants so long as (a) any of our Indebtedness is issued and outstanding, or (b) a commitment to purchase or extend Indebtedness from or to us is in effect. In the
future, when we issue new Indebtedness, the agreements or instruments evidencing or governing the new Indebtedness may require us to comply with additional covenants, or may excuse us from compliance with some of the covenants of the fiscal agency
agreement we list in this annual report. However, these variations will only apply to the new Indebtedness, and not to our existing Notes.

##### Table of Contents

Negative Pledge

We will not, directly or indirectly, incur any lien, other than a lien permitted under the fiscal agency agreement on or with regard to any of our property or assets in order to secure Indebtedness unless this lien
secures our outstanding Indebtedness equally and ratably.

This prohibition applies to all kinds of property, real, personal or mixed,
including tangible and intangible property, including capital stock.

When we use the term lien we mean, with respect to any
property of any kind, any mortgage or deed of trust, pledge, hypothecation, assignment, security interest or other security or similar agreement of any kind on or with respect to the property, including any conditional sale or other title retention
agreement that has substantially the same economic effect as any of the foregoing.

Under the fiscal agency agreement, however, we are
permitted to incur permitted liens, including liens used to secure the purchase price of any kind of property or assets we acquired after the date of the fiscal agency agreement, or to secure Indebtedness incurred solely to finance the
acquisition of property or assets we acquired after the date of the fiscal agency agreement, in both cases other than receivables we purchase under the receivables purchase agreement. In addition:



| |  |  | a permitted lien must be limited to the related property or asset;
| | - |  | ------------------------------------------------------------------



| |  |  | any Indebtedness it secures must be for an amount that does not exceed the purchase price of the relevant property or asset;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | a permitted lien must be created within 180 days of the acquisition of the relevant property or asset; and
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | the aggregate amount of Indebtedness outstanding at any one time that is secured by permitted liens cannot exceed U.S.$1,000,000.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------

Use of Proceeds

We will apply the
net proceeds of all the Indebtedness we incur to:



| |  |  | purchase eligible receivables of designated customers generated or to be generated from PMI Services in accordance with the receivables purchase agreement;

Financial Covenants

We agree to
comply with certain financial covenants on each date of determination. By date of determination, we mean the first day of every month, any date on which we incur Indebtedness or any date on which we make a restricted payment, as
described below in Limitation on Restricted Payments. More specifically, on these dates of determination we will not allow:



| |  |  | the total liabilities to equity ratio to be greater than 7 to 1. By total liabilities to equity ratio, we mean the aggregate outstanding principal amount of all
Indebtedness that we incur, other than subordinated debt provided by Petróleos Mexicanos, divided by our Equity. Equity includes our total paid-in capital, retained earnings and reserves, as well as the subordinated debt which
Petróleos Mexicanos provided to us. In order to be included in the determination of Equity, subordinated debt must be subordinated in accordance with the fiscal agency agreement; or

| |  |  | the debt service coverage ratio to be less than 3 to 1. By debt service coverage ratio, we mean, during the 90-day period preceding each of these dates, the sum
of:
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------

(1) the aggregate amount of payments made to us by obligors on the purchased receivables,

(2) capital contributions, including the proceeds of the subordinated debt held by
Petróleos Mexicanos or any of its Affiliates that is subordinated in accordance with the fiscal agency agreement, in the form of cash or permitted investments as described below in Limitation on Transfers of Receivables;
Investments, (net of restricted payments during that period), and

(3) income from permitted investments,

divided by the maximum aggregate amount of scheduled debt service for any fiscal quarter during which our Indebtedness is outstanding.

By debt service we mean all interim and final (at scheduled maturity, upon acceleration or otherwise) payments of principal,
including any amount in respect of original issue discount, of, and premium, if any, and interest on, including additional amounts or similar gross-ups in respect of taxes, and other amounts, including fees and commissions, in respect of our
Indebtedness, including any payments, prepayments, redemptions and repurchases of Indebtedness.

By scheduled debt service we
mean, on any date, payments of principal of, and premium, if any, interest on, and other amounts, including fees and commissions, in respect of our Indebtedness that are scheduled to become due and payable on or after that date in amounts that are
determinable as of that date, assuming prevailing interest rates in the case of floating rate Indebtedness.

Debt Incurrence

We will not incur Indebtedness unless, after giving effect to the new Indebtedness,



| |  |  | the total liabilities to equity ratio is not greater than 7 to 1;
| | - |  | -----------------------------------------------------------------



| |  |  | the debt service coverage ratio is not less than 3.5 to 1; and
| | - |  | --------------------------------------------------------------



| |  |  | no event of default or specified event, as described below in Events of Default and Specified Events, shall have occurred and be continuing.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------

Compliance with Receivables Documents

We will perform and comply with each of our obligations, covenants and agreements under the receivables purchase agreement, the servicing and collection agency agreement, the letter agreement and the designated
customer notices. To the extent that any provision in any of these documents (a) permits us to waive compliance with that provision or (b) requires that we find any document, opinion or other instrument or any event or condition acceptable
or satisfactory, for purposes of the fiscal agency agreement, we will comply with that provision only if: the waiver is permitted or approved in accordance with each debt agreement under which any of our Indebtedness was issued and is outstanding or
under which any commitment to purchase or extend our Indebtedness is in effect; and the document, opinion, instrument, event or condition is so permitted or approved.

No amendment to, or waiver of, any provision of defined terms made pursuant to the receivables purchase agreement, the servicing and collection agency agreement, the letter agreement or the designated customer notices
will be effective unless it is permitted or approved in accordance with the terms of our debt agreements.

Payment of Obligations;
Compliance With Obligations

We agree to pay, discharge or otherwise satisfy at or before maturity or before they become delinquent, as
the case may be, all of our obligations, except where:



| |  |  | the amount or validity of the obligation is currently being contested in good faith by appropriate proceedings and reserves regarding the obligation in conformity with IAS (now
IFRS) or U.S. GAAP, as applicable, have been provided on our books; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the failure to pay, discharge or otherwise satisfy the obligation would not have a Material Adverse Effect.
| | - |  | -----------------------------------------------------------------------------------------------------------

We shall defend or, in accordance with the servicing and collection agency agreement, cause the servicer
to defend, all of our rights, title and interest in, to and under the purchased receivables, whether now existing or to be generated in the future, against all claims of third parties. We will fulfill all our material obligations in connection with
each purchased receivable and will do nothing to impair our rights in each purchased receivable.

Books and Records

We agree in all material respects to keep proper books of records and account. We agree to maintain full, true and correct entries in these books in
conformity with IAS (now IFRS) or U.S. GAAP, as applicable, as well as all requirements of law of all dealings and transactions in relation to our business and activities.

For purposes of this annual report, when we use the term requirements of law we mean, as to any person, (a) the certificate of
incorporation and by-laws or other organizational or governing documents of that person, and (b) any law, treaty, rule or regulation or a final determination of a court or other governmental authority. In each case, we mean those documents,
laws, treaties, rules, regulations or determinations which are applicable to or binding upon that person or any of its property or to which that person or any of its property is subject. However, if the violation of any provision of such document,
law, treaty, rule, regulation or final determination will not have a Material Adverse Effect, then that document or law will not be a requirement of law.

Compliance with Law and Contractual Obligations

We agree to comply with all requirements of law and
the provisions of the receivables purchase agreement, the servicing and collection agency agreement, the letter agreement, the designated customer notices, the fiscal agency agreement, each of our debt agreements, the crude oil sale agreement

If a designated customer pays collections directly to us, we agree to transfer or deposit those collections into the
collection account as soon as practicable in accordance with the servicing and collection agency agreement.

Separate Corporate
Existence

We agree:

(a) to maintain our own deposit account or accounts. None of Petróleos Mexicanos or its Affiliates will have independent access to our deposit accounts. However, PMI and Petróleos Mexicanos will have
independent access to them in their capacities as servicer and investment manager and in accordance with the servicing and collection agency agreement and the investment management agreement. We will not commingle our funds with the funds of
Petróleos Mexicanos or any of its Affiliates;

with any of our shareholders or with Petróleos Mexicanos or any of its Affiliates,

| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | each of us shall bear its fair share of the salary and benefit costs associated with the shared officers and other employees;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------

business with vendors or service providers or to share overhead expenses,



| |  |  | the costs incurred shall be allocated fairly among us, and

(d) that, to the extent we contract or do business with vendors or service providers
where the goods and services provided are partially for the benefit of any of our shareholders or Petróleos Mexicanos or any of its Affiliates,

PMI, PEP, PMI Services and their Affiliates. However, our office space may be located at the same address as Petróleos Mexicanos, PMI, PEP, PMI Services or one or more of the Affiliates. Moreover, we may not maintain office space in the
United States or Mexico;

(g) that, to the extent we and any of our shareholders or Petróleos Mexicanos or any of its
Affiliates have offices in the same location, we shall make a fair and appropriate allocation of overhead costs among us. Further, each of us shall bear our fair share of those expenses;

| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | to qualify and remain qualified in good standing as a foreign corporation in each jurisdiction where that qualification is required, other than any jurisdiction where our failure to
qualify would not have a Material Adverse Effect.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Assessment

We agree to pay and discharge all taxes, assessments, levies and other governmental charges that are imposed on us. However, we do not need to meet this
requirement for taxes, assessments, levies and other governmental charges:



| |  |  | that are being contested in good faith by appropriate proceedings and for which we have set aside on our books adequate reserves in accordance with IAS (now IFRS) or U.S. GAAP, as
applicable, and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | where the failure to pay, satisfy or discharge would not have a Material Adverse Effect.
| | - |  | ----------------------------------------------------------------------------------------

Charter

Limitation on Restricted Payments

With limited exceptions, we shall not:



| |  |  | make any payment on subordinated indebtedness;
| | - |  | ----------------------------------------------



| |  |  | declare or pay any dividend on, or make any payment on account of, or set apart assets for a sinking or other analogous fund for, the purchase, redemption, defeasance, retirement or

| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | make any other distribution in respect thereof.
| | - |  | -----------------------------------------------

Under
the fiscal agency agreement, these three kinds of payments are considered restricted payments.

We may make such payments,
declarations or distributions if, after giving effect to that restricted payment:



| |  |  | no event of default, specified event or event or condition that would constitute an event of default or specified event, as described below in Events of Default
and Specified Events, with notice or in the future shall have occurred and be continuing; and

We shall not make any payment in respect of unscheduled optional or mandatory prepayments, redemption or repurchases of our Indebtedness, whether
directly or indirectly, whether in cash or our property or obligations, unless the payment is of debt service that has been declared immediately due and payable following the occurrence of a default or an event of default under any of our debt
agreements. However, we may make these payments if, after giving effect to the restricted payment as if it were included in the payment of principal, interest, premium and other amounts (including fees and commissions) on our Indebtedness that is
scheduled to become due and payable on or after we make the restricted payment:



| |  |  | no event of default, specified event or event or condition that would constitute an event of default or specified event, as described below in Events of Default
and Specified Events, with notice or in the future shall have occurred and be continuing; and

Events of Default

Under the terms of the fiscal agency agreement, each of the following constitutes an event of default:

(a) our failure to comply with our obligations (1) to maintain and fund the retention account as described below under Funding and Administration of Retention Account, which failure shall
continue for seven business days, or (2) to maintain and fund the liquidity facility as described below under Liquidity Facility, which failure shall continue for 30 business days;

(b) our failure to remedy a breach of



| | (1) | (x) the Total Liabilities to Equity Ratio covenant or
| | --- | -------------------------------------------------------



| |  | (y) the Debt Service Coverage Ratio covenant
| |  | ----------------------------------------------



| |  | by obtaining contributions to our Equity to the extent necessary to restore compliance on a pro forma basis with the applicable covenant after giving effect thereto within 60 days
after such breach, including on any date of determination; or
| |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) | any covenant under the fiscal agency agreement in any material respect (other than those covenants referred to in paragraphs (a) and (b)(1) above in this sub-section of
this annual report) within 60 days after such breach;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For purposes of determining whether a failure to comply
with the Debt Service Coverage Ratio covenant or the Total Liabilities to Equity Ratio covenant has been cured, any capital contributions obtained after we became aware of the failure to comply will be considered payments
made to us by obligors on purchased receivables during the three months immediately prior to such failure.

(c) some events
of bankruptcy, insolvency, suspension of payments, liquidation, dissolution or reorganization relating to PMI Services, PMI (unless a novation of the crude oil sale agreement governing PEPs sale of crude oil to PMI is in effect), PEP,
Petróleos Mexicanos or us;

(d) the occurrence of a change of control that is accompanied by a Rating Decline;

By change of control, we mean the occurrence of any of the following events:



| |  |  | Pemex Finance Trust ceases to be the beneficial owner, as defined in Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934, directly or indirectly, of 100% of
our issued and outstanding capital stock, and there is a reasonable likelihood that that change will have an adverse effect on the holders of the Notes;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We consolidate with, or merge into or with, another person, or we sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of our assets;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Petróleos Mexicanos or its successor ceases to be the beneficial owner, directly or indirectly, of at least a majority of the issued and outstanding voting shares of PMI or
PMI Services; or
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PEP sells, assigns, conveys, transfers, leases or otherwise disposes of all or substantially all of its oil producing assets (directly or indirectly, by way of merger, transfer of
assets or shares of capital stock, or otherwise) to an entity other than Petróleos Mexicanos or its successor, or an Affiliate controlled, directly or indirectly, by Petróleos Mexicanos or its successor, which assumes all of the
obligations of PEP under the receivables purchase agreement, the servicing and collection agency agreement, the letter agreement, the designated customer notices and the crude oil sale agreement.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(e) our failure to make any payment of principal on our Indebtedness at maturity, including any applicable grace period, in an amount in
excess of U.S.$10,000,000 (or the equivalent thereof in any other currency or composite currencies), when the failure has continued for a period of 30 days after our receipt of an Issuer Notice notifying us of that failure;

##### Table of Contents

(f) our default on any Indebtedness, if that default results in the acceleration of
Indebtedness in an amount in excess of U.S.$10,000,000 (or the equivalent thereof in any other currency or composite currencies) without that Indebtedness having been discharged or such acceleration having been cured, waived, rescinded or annulled
for a period of 30 days after our receipt of an Issuer Notice notifying us of that default.

However, if any of the
failures, defaults or accelerations referred to in this clause (f) or clause (e) above shall cease or be cured, waived, rescinded or annulled, then the event of default arising by reason of that failure, default or acceleration shall
likewise be considered cured;

(g) if we fail to have, at any time and for a period of five business days,

(1) a valid unencumbered ownership interest in purchased receivables sold under the receivables purchase agreement, valued at the
purchase price paid for that receivable, whether existing as of such date or to be generated thereafter; and

(2) a valid
unencumbered ownership interest in cash, cash equivalents and permitted investments in excess of an amount equal to the sum of the next payment of scheduled debt service for all debt agreements under which Indebtedness is outstanding at such date;

and the aggregate value of (1) and (2) together is less than the outstanding principal amount of our Indebtedness
as of the date of determination. However, if that failure results from a defect in the validity of the ownership interest or an encumbrance which may be cured or removed, and we are taking steps to effect the cure or removal, then the failure will
have to have continued for a period of 10 days for it to constitute an event of default.

By next payment of scheduled
debt service, we mean, on any date of determination for any debt agreement, the amount of the first payment of scheduled debt service on the outstanding Indebtedness under that debt agreement that is scheduled to be paid after that date of
determination. Amounts scheduled to be paid on the same date shall be treated as a single payment whether the amounts are principal, interest or otherwise.

(h) if:



| |  |  | any designated customer which is an Affiliate of Petróleos Mexicanos directly or indirectly makes a payment with respect to purchased receivables into or for the account of
Petróleos Mexicanos, PMI, PMI Services or any other Subsidiary of Petróleos Mexicanos;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PMI does not deliver, or cause to be delivered, that payment to the relevant collection agent for deposit in the collection account; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PMIs failure to deliver, or cause to be delivered, continues for 7 business days after the payment was made to or for the account of Petróleos Mexicanos, PMI, PMI
Services or any other Subsidiary of Petróleos Mexicanos;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(n) we fail to purchase eligible receivables, generated or to be generated, arising out
of the sale of crude oil other than Maya crude oil within 10 business days after the date when we are required to do so under the receivables purchase agreement; or

(o) we fail to add a new customer to the list of designated customers within 60 days of the date when we are required to do so under the
receivables purchase agreement.

The Issuer Notice mentioned above in connection with certain events of default is a written
notice sent to us by a holder of our Indebtedness, or the relevant trustee or other representative of the holder, specifying that it is an Issuer Notice for purposes of the fiscal agency agreement. To the extent that the debt agreement under which
the relevant Indebtedness is issued specifies procedures, requirements or conditions for the giving of an Issuer Notice, the notice must be given in compliance with these requirements.

Any individual debt agreement may provide that one or more of the foregoing events of default do not apply to debt issued under such agreement or may
include additional or different events of default. However, such variations shall only apply to the Indebtedness issued under such debt agreement, and not to the Notes.

Specified Events

Under the terms of the fiscal agency agreement, each of the following
constitutes a specified event:

(1) upon notification to us pursuant to a Specified Event Notice,



| |  |  | our failure to comply with any covenant referred to in clause (b)(1) above under Events of Default and the continuation of that failure; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PMIs failure to comply in any material respect with its obligation under the receivables purchase agreement to cause the monthly average amount of eligible receivables of
designated customers generated by PMI during any consecutive twelve-month period that are not subject to any encumbrance other than under the receivables purchase agreement to represent at least the lesser of:
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 20 million barrels of Maya crude oil; and
| | - |  | -----------------------------------------



| |  |  | 80% of PMIs total eligible receivables generated from sales of Maya crude oil;
| | - |  | -------------------------------------------------------------------------------

(2) an event of default in paragraph (g) under Events of Default shall have occurred and be continuing, or

(3) any other event or condition that is identified as a special event in any of our debt agreements.

Liquidity Facility

Under the
fiscal agency agreement, we have established and are required to maintain a liquidity facility at all times. The liquidity facility is made up of:



| |  |  | an account with the fiscal agent which is called the liquidity account and
| | - |  | ----------------------------------------------------------------------------



| |  |  | acceptable letters of credit delivered to the fiscal agent as described under Acceptable Letters of Credit below.
| | - |  | --------------------------------------------------------------------------------------------------------------------

On any date, the balance of cash and permitted investments in the account with the fiscal agent plus the amount of any acceptable letters of credit must
be at least equal to the sum of the next payment of scheduled debt service for all debt agreements under which we have indebtedness outstanding.

We shall deposit, or shall cause to be deposited, with the fiscal agent no later than 10 a.m., New York time, on each business day the amount necessary to ensure that the amount on deposit is sufficient to pay debt service in respect
of our Indebtedness on that business day. If by 10 a.m., New York time, on any business day the funds on deposit with the fiscal agent are insufficient to pay the debt service due and payable on that business day, then the fiscal agent shall
draw from the liquidity facility, if it is available, an amount equal to the amount of that insufficiency on the same business day.

##### Table of Contents

Acceptable Letters of Credit

Instead of holding cash or cash equivalents in the liquidity account, we may provide the fiscal agent with one or more acceptable letters of credit which
by their terms require that any drawing on them be deposited in the liquidity account. In this annual report, when we use the term acceptable letter of credit, we mean an irrevocable letter of credit that has been issued to and for the
benefit of the fiscal agent for the account of someone other than us. In order to be an acceptable letter of credit, a letter of credit:



| |  |  | must be issued by an office located in the United States of a bank or trust company which is organized under the laws of the United States or any state thereof that has both a
short-term deposit rating of at least P-1 and A-1 and long-term deposit rating of at least A-2 or its equivalent by Moodys and A by Standard & Poors and, if rated by either of Duff & Phelps or Fitch, by any such rating
agency. If at any time the issuer of a letter of credit shall cease to meet these requirements, then the letter of credit shall cease to be an acceptable letter of credit; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | must by its terms have an initial expiration date at least one year beyond its date of issuance and provide that:
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | the letter of credit will be automatically renewed for a period of at least one year beyond its then current expiration date unless the issuer of the letter of credit provides a
written termination notice to the fiscal agent at least 20 business days prior to its then current expiration date; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if we have delivered a termination notice, the fiscal agent shall be entitled, at an office located in the Borough of Manhattan, The City of New York, to draw the full amount
available to be drawn under the letter of credit at any time after its receipt of the termination notice and prior to the expiration of the letter of credit. The amount is to be deposited in an account with the fiscal agent.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

After we deliver one or more acceptable letters of credit to the fiscal agent, if the amount held in the liquidity facility
is greater than the aggregate amount of the next payment of scheduled debt service for all debt agreements under which we have debt outstanding, the fiscal agent shall release to us, if available in the liquidity account, an aggregate amount of cash
(and, if necessary, liquidate investments held in the liquidity account) necessary to reduce the amount of the liquidity facility to the aggregate amount of the next payment of scheduled debt service for all debt agreements under which we have debt
outstanding. The fiscal agent shall return any acceptable letter of credit to us or as we direct upon the deposit by a person or entity, other than us, of cash or cash equivalents into the liquidity account available to be drawn by the fiscal agent
under that acceptable letter of credit for deposit in the liquidity account. Unless the fiscal agent receives written notice from the issuer of any acceptable letter of credit at least 5 days prior to the date of expiration of the letter of
credit that it has been renewed, the fiscal agent shall draw the full amount available thereunder and deposit the amount paid pursuant to such drawing in the liquidity account.

Payment of Accelerated Debt Service

Each of our debt agreements shall expressly provide, and each holder of our Indebtedness upon becoming a holder shall be deemed to agree, that



| |  |  | that holder shall only be entitled to receive payment of accelerated debt service in respect of that Indebtedness. By accelerated debt service, we mean any debt service
which has been declared immediately due and payable (or in the case of a credit enhancement provided with respect to its debt service, the reimbursement obligation has been declared due and payable) after the occurrence of a default or an event of
default under any debt agreement, and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | that holder shall not ask, demand, sue for, take or receive from us, by set-off or in any other manner, or retain, payment (in whole or in part) of accelerated debt service other
than such holders ratable share of amounts, if any, on deposit in the retention account.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

However, that agreement shall automatically cease to have any force and effect upon the occurrence and
during the continuance of:



| |  |  | any event of default of the type referred to in clauses (a), (b)(1)(x), (c), (d), (g), (h), (i), (j)(B), (k)(A)(2), (k)(B), (l) or (m) above under Events
of Default or
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an event of default of the type referred to in any of our debt agreements which under the terms of that debt agreement triggers a diversion of 100% of collections to the retention
account in the same manner as such clauses pursuant to the fiscal agency agreement.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Nonetheless, the right of any person to
enforce the receivables purchase agreement, the servicing and collection agency agreement, the letter agreement and each designated customer notice against any party thereto or to exercise any right thereunder shall not be limited.

Funding and Administration of Retention Account

Under the fiscal agency agreement, we have established and are required to maintain an account with the fiscal agent designated as the retention account.

The provisions of the fiscal agency agreement governing the retention account are only triggered when we receive one or the other of certain notices from
holders of our indebtedness, called the Specific Event Notice and the Acceleration Notice, and while this notice remains in effect. For a more complete discussion of what we mean by these terms, see Glossary of Certain
Defined Terms Used Primarily Under the Captions Description of Principal Agreements and Description of the Indenture.

On each business day during a period when a Specified Event Notice and/or an Acceleration Notice is in effect, we, or the fiscal agent on our behalf, have agreed to instruct all collection agents to transfer, to the extent available in the
collection account, amounts to the retention account as follows:



| |  |  | if an Acceleration Notice is in effect and we have received an Acceleration Notice or an Issuer Notice specifying that an event of default of the types referred to in
clause (a), (b)(1)(x), (c), (d), (g), (h), (i), (j)(B), (k)(A)(2), (k)(B), (l) or (m) under Events of Default above shall have occurred and be continuing, on each business day 100% of all collections paid into the
collection account on the immediately preceding business day on receivables we have purchased under the receivables purchase agreement;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in all other cases, 25% of the amount by which the aggregate collections deposited into the collection account on the immediately preceding business day exceed the aggregate amount
of debt service (excluding any accelerated debt service) that was paid on the immediately preceding business day.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In
addition, an event of default in any debt agreement which, under the terms of that debt agreement, triggers a diversion of 100% of collections to the retention account, will also result in the retention of 100% of collections under the fiscal agency
agreement.

Any amounts on deposit in the retention account on any business day shall be applied to pay accelerated debt service, if any,
that is due and payable on that day. While a Specified Event Notice is in effect but no Acceleration Notice is in effect, we agree to maintain in the retention account at all times an amount at least equal to the aggregate amount of funds required
to be transferred from all collection accounts to the retention account following the delivery of the Specified Event Notice. All such payments shall be paid to holders of Indebtedness in proportion to amounts of accelerated debt service due and
unpaid to them. Pending distribution to holders of Indebtedness, amounts held in the retention account shall be invested by the fiscal agent in permitted investments as directed by us or someone we appoint.

The collection agent will continue to transfer funds to the retention account until it receives a notice from the fiscal agent to cease doing so.

Investment of Funds in Liquidity Account and Retention Account

We, or the investment manager on our behalf, shall instruct the fiscal agent as to the investment of funds (or variation or redemption of such
investments) in the liquidity account and the retention account on our behalf. However, (1) such investments must only be in permitted investments and (2) for purposes of the liquidity account, such investments must have final maturities
consistent with ensuring that sufficient cash to pay the next payment of scheduled debt service for each of our outstanding debt agreements is available in the liquidity account.

The Servicing and Collection Agency Agreement

The servicing and collection agency agreement governs
the treatment and allocation of collections upon the receivables. In this annual report, when we say collection, we mean all amounts received from the designated customers on the purchased receivables when due in the form of cash,
checks, wire transfers or any other form of cash payment. The term also includes:



| |  |  | any late payment or default, interest or finance charges assessed against or payable by any customer because that customer has failed to make timely payment in full;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | all collections received in respect of the related property. For a more complete description of what related property is, see The Designated Customers and Eligible
ReceivablesThe Eligible Receivables;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | all proceeds of the receivables and collections thereof, including collections evidenced by an account, note, instrument, letter of credit, contract, security agreement, chattel
paper, general intangible or other evidence of indebtedness or security;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | whatever is received upon the sale, exchange, collection or other disposition of, or any indemnity, warranty or guarantee payable in respect of, the foregoing; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | all proceeds as defined in Section 9-306 of the Uniform Commercial Code as in effect in the State of New York.
| | - |  | ----------------------------------------------------------------------------------------------------------------

Under the servicing and collection agency agreement, UBS AG was appointed to act as the initial collection agent and PMI was appointed to act as the
servicer. On October 1, 1999, Standard Chartered Bank replaced UBS AG as collection agent, in accordance with the terms of the servicing and collection agency agreement. Standard Chartered Bank is one of a number of banks with which PMI and
Petróleos Mexicanos maintain ordinary banking relationships. When we use the term collection agent in this annual report, we mean it to include not only Standard Chartered Bank, but also any of Standard Chartered Banks
successors appointed in accordance with the servicing and collection agency agreement. Likewise, when we use the term servicer, we intend it to include not only PMI, but also any of PMIs successors appointed in accordance with that
agreement.

The Collection Account

The collection account is an account established in the name of PMI, PMI Services and us, which is administered by the collection agent. The designated customers make their payments for crude oil they purchase from
PMI into the account, regardless of whether they are buying Maya crude oil or another type of crude oil. In accordance with instructions provided by the servicer, the collection agent allocates the funds held in the collection account to us, PMI
Services, PMI, or the retention account, as described below.

Duties of the Collection Agent

The primary responsibility of the collection agent is to transfer payments on each receivable which have been paid into the collection account to the
owner of that receivable. Because the designated customers make all their payments, not just those on the purchased receivables, into the account, the collection agent has to allocate



54



---

##### Table of Contents

the funds between PMI, PMI Services and us. No distribution of collections to us, PMI or PMI Services will be considered definitive until the servicer,
relying on information supplied by PMI and the designated customers, determines the proper allocation of each collection. We, PMI and PMI Services have agreed to return any over-payments made to us. Each collection agent will transfer funds
corresponding to our interest in any collection account that we, PMI Services and PMI maintain with it within one business day of receiving transfer instructions from the servicer. However, the collection agent will not follow the servicers
instructions to transfer funds if the fiscal agent has instructed it to instead transfer funds to the retention account, as described in The Fiscal Agency AgreementFunding and Administration of Retention Account.

The collection agent will also deliver a report to the servicer on each business day on which it receives collections in its collection account,
indicating the amount of collections deposited. The collection agent will invest any amounts remaining in its collection account overnight on our behalf, as Petróleos Mexicanos, acting as investment manager, instructs. The collection agent
has no obligation to any party to make inquiries about the performance of any party under the receivables purchase agreement and the servicing and collection agency agreement. It also has no obligation to inspect the books, properties or records of
the servicer.

We, PMI and PMI Services will pay the collection agent reasonable and documented fees and reimburse the collection agents
for their reasonable and documented expenses in connection with the performance of their obligations. A collection agent may resign by giving at least 90 days notice. In addition, either PMI or we may remove a collection agent:



| |  |  | if it fails to perform its duties, or
| | - |  | -------------------------------------



| |  |  | if it ceases to meet the qualifications specified in the servicing and collection agency agreement.
| | - |  | ---------------------------------------------------------------------------------------------------

A collection agent must be (1) a bank or trust company organized under the laws of the United States or any state of the United States or
(2) the branch of a foreign bank, in each case having an office located in New York City. In addition, each collection agent must meet minimum financial standards specified in the servicing and collection agency agreement.

Duties of the Servicer

The
servicer manages, services, administers and collects any receivables of designated customers that have been sold by PMI to PMI Services and thereafter to us. The servicer has full power and authority to do all things necessary to complete these
duties, including the defense of our right, title and interest, and, if applicable, the right, title and interest of PMI and PMI Services, to the receivables and collections upon those receivables. The servicer has agreed to take all commercially
reasonable steps to collect, and hold any collections it may receive in trust, for the benefit of PMI, PMI Services or us. The servicer covenants:



| |  |  | not to discharge any receivable sold to us nor to release any designated customer from its obligations with respect to any such purchased receivable except (a) with our consent
or the consent of PMI Services, as applicable; (b) upon payment in full of that purchased receivable; or (c) in accordance with the terms of the receivables purchase agreement, the servicing and collection agency agreement, the letter
agreement and each designated customer notice;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | not to take any action or cause any person to take any action that would impair our rights or the rights of PMI Services in any purchased receivable;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | not to create, incur or assume any lien upon or with respect to any purchased receivable, except as permitted by the receivables purchase agreement; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to furnish us, PMI Services and the collection agent with an annual report prepared by an internationally recognized independent certified public accountant stating that the
servicer is in compliance, and that all related accounts, records and computer systems are properly prepared and maintained in accordance with, the servicing and collection agency agreement.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

We, PMI Services and, in the event that PMI ceases to be the servicer, PMI will pay the servicer
reasonable and documented fees and reimburse the servicer for its reasonable and documented expenses in connection with the performance of its obligations. We may remove PMI as servicer if:



| |  |  | it fails to perform its material servicing obligations and this failure continues for 30 days following notice from us; or
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | it willfully breaches any provision of the receivables purchase agreement that restricts or prohibits the sale of receivables of any designated customer or results in collections in
respect of purchased receivables not being paid to the collection account.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If a successor has been appointed we may remove
any successor servicer at any time.

Representations and Warranties

Each of PMI and PMI Services represents, among other things, that neither the execution, delivery nor performance by it of the servicing and collection
agency agreement:



| |  |  | violates any law or decree of any governmental authority of the United States, The Netherlands, the Cayman Islands or Mexico;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | breaches any term of, constitutes a default under or results in the creation of a lien upon any of its property or assets under any indenture, credit agreement or contract; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | violates any provision of its by-laws.
| | - |  | --------------------------------------

PMI has also
agreed to:



| |  |  | invoice each designated customer receiving a shipment of crude oil and instruct such designated customer to deposit all collections on purchased receivables into the collection
account;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintain at its offices a file of all relevant documents relating to the receivables of the designated customers for the benefit of PMI Services, the servicer and us;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | indemnify and hold harmless PMI Services, any successor servicer and us from all liabilities and losses resulting from any failure of PMI to perform its obligations under the
servicing and collection agency agreement;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | remain as servicer and not resign so long as the servicing and collection agency agreement remains in effect or receivables of designated customers are required to be generated,
sold to us and collected. However, in the event of a novation, PMI Services shall replace PMI as servicer; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | indemnify and hold harmless the collection agent and its successors, assigns, agents and servants from all claims, liabilities or losses asserted against the collection agent,
arising out of its execution of the servicing and collection agency agreement or arising from its good faith performance of its duties under that agreement.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Governing Law, Jurisdiction and Waiver of Immunity

The servicing and collection agency
agreement is governed by and interpreted in accordance with the laws of the State of New York, with the following exceptions:



| |  |  | the laws of Mexico govern the authorization and execution of the agreement by Petróleos Mexicanos and PMI;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | the laws of The Netherlands govern the authorization and execution of the agreement by PMI Services; and
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | the laws of the Cayman Islands govern our authorization and execution of the agreement.

We and Petróleos Mexicanos have appointed the Consul General of Mexico in New York City and his
successors as our process agent. PMI and PMI Services have appointed Curtis, Mallet-Prevost, Colt and Mosle acting through their office in New York as their process agent. This means that process may be served on these agents in any action based
upon the servicing and collection agency agreement upon whom process may be served in any action based upon the agreement which may be instituted in the Supreme Court of the State of New York, County of New York, any federal court sitting in the
Borough of Manhattan, The City of New York and any appellate court or body thereto. We, Petróleos Mexicanos, PMI and PMI Services have each:



| |  |  | irrevocably submitted to the jurisdiction of any such court in respect of any such action;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | waived, to the fullest extent permitted by law, any objection which any of us may have now or later to the laying of venue of any such action in any such court; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | waived any right to which we may be entitled on account of residence or domicile.
| | - |  | ---------------------------------------------------------------------------------

Petróleos Mexicanos and PMI have reserved the right to plead sovereign immunity under the Immunities Act with respect to actions brought against them under United States federal securities laws or any state
securities laws, and each of Petróleos Mexicanos and PMIs appointment of the applicable process agent as its agent for service of process will not extend to these actions. In the absence of this waiver of immunity by
Petróleos Mexicanos it would not be possible to obtain a judgment in an action brought in a United States court against Petróleos Mexicanos, unless such court were to determine that Petróleos Mexicanos is not entitled under the
Immunities Act to sovereign immunity with respect to that action. The same is true of PMI. Even if a United States judgment could be obtained in any such action under the Immunities Act, it may not be possible to obtain in Mexico a judgment based on
such a United States judgment. Moreover, execution upon property that Petróleos Mexicanos may have in the United States to enforce a judgment obtained under the Immunities Act may not be possible except under the limited circumstances
specified in the Immunities Act.

Article 27 of the Political Constitution of the United Mexican States, Articles 6 and 13 (formerly
Articles 16 and 60) of the General Law on National Patrimony (and other related articles), Articles 1, 2, 3, 4 (and related articles) of the Regulatory Law, Articles 15, 16 and 19 of the Regulations to the Regulatory Law, Articles 1, 2, 3, 4 (and
other related articles) of the Organic Law of Petróleos Mexicanos and Subsidiary Entities and Article 4 of the Federal Code of Civil Procedures of Mexico establish, among other things, that:



| |  |  | attachment prior to judgment, attachment in aid of execution and execution of a final judgment may not be ordered by Mexican Courts against property of Petróleos Mexicanos
and PMI;

petroleum (including petroleum products) and natural gas that are susceptible of being used as basic industrial raw materials that constitute basic petrochemicals (the petroleum industry) are reserved exclusively to Mexico
(and, to that extent, assets related thereto are entitled to immunity); and

| |  |  | the public entities created and appointed by the Federal Congress of Mexico to conduct, control, develop and operate the petroleum industry of Mexico include Petróleos
Mexicanos and PEP. Therefore, Petróleos Mexicanos is entitled to immunity in respect to such exclusive rights and power.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result, notwithstanding Petróleos Mexicanos waiver of immunity described in the preceding paragraph, a Mexican court may not enforce a judgment against Petróleos Mexicanos by ordering the attachment of its assets.

The Letter Agreement

Petróleos Mexicanos has agreed with us in the Letter Agreement to cause PEP, PMI and PMI Services to comply with their material obligations under the receivables purchase agreement and the crude oil sale
agreement governing the sale of crude oil by PEP to PMI. In the letter agreement, Petróleos Mexicanos makes representations and warranties as to:



| |  |  | its valid existence;
| | - |  | --------------------



| |  |  | its authority to enter into the letter agreement;
| | - |  | -------------------------------------------------



| |  |  | the enforceability of the letter agreement in accordance with its terms; and
| | - |  | ----------------------------------------------------------------------------



| |  |  | the lack of any actions, suits or proceedings at law or in equity by or before any governmental authority, either pending or threatened, (1) that involves the letter agreement
or (2) as to which there is a reasonable possibility of an outcome which would be expected to result in a Material Adverse Effect.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

However, none of Petróleos Mexicanos, PEP, PMI, PMI Services, Petróleos Mexicanos other Subsidiaries or Affiliates or Mexico:



| |  |  | in any way guarantees payment of the purchased receivables;
| | - |  | -----------------------------------------------------------



| |  |  | will be liable for nonpayment of any purchased receivable by any designated customer; or
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | will be liable to indemnify any person against any claims or losses suffered by us as a result of a failure by any designated customer to make timely payments on account of
purchased receivables.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Governing Law, Jurisdiction and Waiver of Immunity

In the letter agreement, Petróleos Mexicanos has appointed the Consul General of Mexico in New York City and his successors as process agent upon
whom process may be served in any action based upon the letter agreement which may be instituted in any federal court sitting in the Borough of Manhattan, The City of New York and any appellate court or body thereto. Petróleos Mexicanos has:



| |  |  | irrevocably submitted to the jurisdiction of any such court in respect of any such action;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | irrevocably waived, to the fullest extent permitted by law, any objection which it may have now or later to the laying of venue of any such action in any such court; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | waived any right to which it may be entitled on account of residence or domicile.
| | - |  | ---------------------------------------------------------------------------------

Petróleos Mexicanos reserves the right to plead sovereign immunity under the Immunities Act with respect to actions brought against it under United States federal securities laws or any state securities laws.
Further, Petróleos Mexicanos appointment of the process agent as its agent for service of process will not extend to such actions. In the absence of a waiver of immunity by Petróleos Mexicanos with respect to such actions, it
would not be possible to obtain a judgment in an action brought in a United States court against Petróleos Mexicanos unless such court were to determine that Petróleos Mexicanos is not entitled under the Immunities Act to sovereign
immunity with respect to such action. However, even if a United States judgment could be obtained in any such action under the Immunities Act, it may not be possible to obtain in Mexico a judgment based on such a United States judgment. Moreover,
execution upon property of Petróleos Mexicanos located in the United States to enforce a judgment obtained under the Immunities Act may not be possible except under the limited circumstances specified in the Immunities Act.

Article 27 of the Political Constitution of the United Mexican States, Articles 6 and 13 (formerly Articles 16 and 60) of the General Law on National
Patrimony (and other related articles), Articles 1, 2, 3, 4 (and related articles) of the Regulatory Law, Articles 15, 16 and 19 of the Regulations to the Regulatory Law, Articles 1, 2, 3, 4 (and other related articles) of the Organic Law of
Petróleos Mexicanos and Subsidiary Entities and Article 4 of the Federal Code of Civil Procedures of Mexico establish, among other things, that:



| |  |  | attachment prior to judgment, attachment in aid of execution and execution of a final judgment may not be ordered by Mexican Courts against property of PMI, Petróleos
Mexicanos and some of the subsidiary entities;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | all domestic petroleum and hydrocarbon resources (whether solid, liquid or gas form) are directly, permanently and inalienably vested in Mexico (and, to that extent, subject to
immunity);

| |  |  | (a) the exploration, exploitation, refining, transportation, storage, distribution and first-hand sale of crude oil, (b) the exploration, exploitation, production and

DESCRIPTION OF THE INDENTURE

We entered into the senior indenture, dated as of December 1, 1998, between ourselves and The Chase Manhattan Bank (now JPMorgan Chase Bank, N.A.),
which serves as trustee. The senior indenture provides the framework under which we may issue debt securities from time to time in one or more series. Each series of our Notes was issued under the senior indenture, in each case as supplemented by a
supplemental indenture, as follows:

##### Table of Contents

The following is a summary of the material provisions of the indenture. It does not purport to be
complete and is subject to the detailed provisions of the senior indenture, which is included as an exhibit to this annual report, as incorporated in this annual report by reference to the registration statement of Pemex Finance and Petróleos
Mexicanos on Form F-4 dated September 30, 1999 (registration statement no. 333-10920).

Copies of the supplemental indentures for the
Notes outstanding are included as exhibits to this annual report as follows:

(b) the supplemental indentures for the February 1999 notes and February 1999 floating rate notes are included as exhibits as incorporated
by reference to the registration statement of Pemex Finance and Petróleos Mexicanos on Form F-4 dated September 30, 1999 (registration statement no. 333-10918);

(c) the supplemental indentures for the July 1999 notes and July 1999 additional issuances are included as exhibits as incorporated by

See also the section entitled Glossary of Certain Defined Terms Used Primarily Under the Captions Description of Principal Agreements and Description of the Indenture, where we define the capitalized
terms that appear in this annual report. The following summary is subject to, and qualified in its entirety by reference to, all the provisions of the indenture and the Notes.

General

All notes issued under the senior indenture are or will be our direct, unconditional,
senior, unsecured and general obligations. These notes enjoy a right of payment prior to the payment of all of our existing and future subordinated Indebtedness, and rank equally in right of payment with all of our existing and future unsecured and
unsubordinated Indebtedness. Moreover, the notes rank equally in right of payment among themselves. None of our assets, including for example, the liquidity facility and the retention account, are or will be pledged or made subject to any lien,
encumbrance or security interest in favor of the holders of our notes. Also, the senior indenture permits us to incur additional Indebtedness, subject to some limitations. As the total amount of our senior debt grows, each holders share of any
distribution in the event of our bankruptcy may be diluted.

Covenants

In the supplemental indentures, we agree that we will observe and perform each of the covenants set forth in the fiscal agency agreement and the senior indenture, so long as any amount payable under any of our Notes
remains unpaid. The covenants found in both of these agreements are incorporated by reference in each supplemental indenture as if they actually appeared in each one. For a more complete explanation of the covenants in the fiscal agency agreement,
see Description of Principal AgreementsThe Fiscal Agency AgreementCovenants.

In the supplemental indentures
for the February 2000 notes, we also agree that so long as any amount payable under any of the February 2000 notes remains unpaid, we will not incur additional Indebtedness if, after giving effect to that incurrence of additional Indebtedness, the
aggregate outstanding principal amount of our senior Indebtedness would exceed U.S.$7.0 billion, unless Standard & Poors, Moodys and one of either Duff & Phelps or Fitch confirm the rating of the notes immediately prior
to that incurrence of additional Indebtedness.

In addition, we agree in the indenture to deliver to the trustee unaudited quarterly financial statements
within 60 days after the last day of the first three fiscal quarters of each fiscal year, and annual audited financial statements within 120 days after the last day of each fiscal year, together with a certificate of an authorized officer stating
that no event of default has occurred and is then continuing or, if an event of default has occurred and is continuing, stating such fact and including a description of the nature of such event of default and the actions that we or any other person
propose to take with respect thereto.

Events of Default

Under the senior indenture, the following events constitute an event of default with respect to any series of notes:

(a) our failure to pay any principal of any of the notes of that series when due, upon redemption, by declaration or otherwise;

(b) our failure to make any payment of any interest or other amount, except principal, on any of the notes of that series,
and our failure continues for 5 or more days;

(c) some events of bankruptcy, insolvency, liquidation, dissolution or
reorganization relating to us, PMI Services, PMI, PEP or Petróleos Mexicanos;

(d) our failure to remedy any material
breach of any covenant under the indenture within 60 days after the breach, other than those covenants incorporated by reference to the fiscal agency agreement;

(e) it becomes unlawful for us to perform any of our obligations under the fiscal agency agreement, the indenture or the notes of that
series. This occurrence will only constitute an event of default if it has, or could reasonably be expected to have, a Material Adverse Effect;

(f) the fiscal agency agreement, indenture or the notes of that series are no longer in full force and effect for a reason not expressly provided for by the terms of that agreement;

(g) if we repudiate the fiscal agency agreement, the indenture, or the notes of that series;

(h) either we or any entity that has assumed our obligations under the relevant agreement revokes or terminates the fiscal agency
agreement, the indenture or any of the notes of that series; or

(i) the occurrence of any event of default
described under Description of Principal AgreementsThe Fiscal Agency AgreementEvents of Default.

If we and the
fiscal agent receive an Acceleration Notice stating that an event of default listed under paragraphs (a), (b), (e), (f), (g), or (h) above has occurred, then the collection agent will send 100% of the collections on the purchased receivables
that we would otherwise receive into our collection account to the retention account instead. As described more fully in the Description of Principal AgreementsThe Fiscal Agency AgreementFunding and Administration of the
Retention Account, the retention account is a separate account established with the fiscal agent which is maintained for the benefit of holders of our Indebtedness who are entitled to receive accelerated payments of principal or interest on
that Indebtedness. If any of the events of default described above occurs and is continuing, the holders of the notes shall have, subject to the terms and conditions of the indenture, and in addition to all other available remedies at law and in
equity, each of the remedies set forth in the indenture. See Description of Principal AgreementsThe Fiscal Agency AgreementEvents of Default.

Acceleration of Payment

If an
event of default occurs and continues with respect to any series of Notes, the trustee has the power to take some actions on behalf of the holders of the Notes. Specifically, the trustee will declare that all principal and interest due from us under
a series of Notes will become due and payable:



| |  |  | at the direction of the holders of more than 50% of the outstanding aggregate principal amount of the Notes of that series if one of the events of default described under paragraphs
(a) or (b) under Events of Default above occurs, or
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



63



---

##### Table of Contents

| |  |  | at the direction of 662/3% of the
outstanding aggregate principal amount of the Notes of that series if one of the events of default described under paragraphs (d), (e), (f), (g), (h) or (i) above occurs.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If the event of default described under paragraph (c) above occurs, acceleration of payments of principal and interest will be automatic, regardless
of what action the trustee takes or fails to take.

If we meet specific conditions, the holders of a majority in principal amount of the
Notes of the affected series then outstanding may annul the trustees declaration of acceleration of payments and waive past events of default. However, the holders may not waive an event of default under any circumstances if it is a continuing
failure to pay principal, premium or interest on the Notes.

However, each holders right to receive accelerated payment of principal
and interest may be limited in some respects. See Description of Principal AgreementsThe Fiscal Agency AgreementPayment of Accelerated Debt Service.

Modification of the Indenture

There are three types of changes we can make to the indenture and the
Notes.

Changes Not Requiring Approval

First, we and the trustee may enter into supplemental indentures without the consent of the holders of the Notes to:



| |  |  | secure one or more series of our notes,
| | - |  | ---------------------------------------



| |  |  | evidence the assumption of our obligations by a successor corporation in accordance with the indenture,
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | add or modify covenants to provide further protection for the holders of our notes,
| | - |  | -----------------------------------------------------------------------------------



| |  |  | cure any ambiguity or correct any inconsistency in the indenture,
| | - |  | -----------------------------------------------------------------



| |  |  | establish the forms or terms of additional notes, and
| | - |  | -----------------------------------------------------



| |  |  | evidence the acceptance of appointment by a successor trustee.
| | - |  | --------------------------------------------------------------

Changes Requiring Majority Approval

Second, if we have the consent of the holders of at least a majority in the
aggregate principal amount of our notes, including the Notes of all series then outstanding and affected (voting as one class), the indenture also allows the trustee and us to:



| |  |  | add any provisions to the indenture,
| | - |  | ------------------------------------



| |  |  | change the indenture in any manner,
| | - |  | -----------------------------------



| |  |  | eliminate any provisions of the indenture, including any provision of the fiscal agency agreement incorporated by reference in the indenture, and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | modify the rights of the holders of the Notes of each affected series in any manner.
| | - |  | ------------------------------------------------------------------------------------

Changes Requiring Each Holders Approval

Third, there are changes that we cannot make
without the approval of each holder of an outstanding note, including any Note, affected by the change. The following lists those types of changes:



| |  |  | extension of the stated maturity of the principal of any note,
| | - |  | --------------------------------------------------------------



| |  |  | reduction in the principal amount of any note,
| | - |  | ----------------------------------------------

##### Table of Contents

| |  |  | reduction in the rate or extension of the time of payment of interest on any notes,
| | - |  | -----------------------------------------------------------------------------------



| |  |  | reduction in any amount payable on redemption of any note,
| | - |  | ----------------------------------------------------------



| |  |  | change in the currency in which the principal (including any amount in respect of original issue discount), premium, if any, or interest on any note is payable,
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reduction in the amount of any original issue discount security payable upon acceleration or provable in bankruptcy,
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | changes to certain provisions of the indenture relating to the notes issued under the indenture which are not denominated in U.S. dollars,
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes that will impair the right to institute suit for the enforcement of any payment on any note when due, and
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | reduction in the percentage in principal amount of notes of any series.
| | - |  | -----------------------------------------------------------------------

Governing Law; Waiver of Immunity

The Notes and the indenture are governed by and interpreted in accordance with the laws
of the State of New York, except that the laws of the Cayman Islands govern our authorization and execution of these documents.

We have
appointed the Consul General of Mexico in New York City and his successors as our process agent for accepting service of legal process. Process may be served with the process agent in any action based upon the Notes which may be instituted in the
Supreme Court of the State of New York, County of New York, any federal court in the Borough of Manhattan, The City of New York and any appellate court or body of those courts.

We have irrevocably submitted to the jurisdiction of any of the above listed courts in respect of any action based upon the Notes. We have irrevocably
waived, to the fullest extent permitted by law, any objection which we may now have or may have in the future to the choice of venue of any legal action in any of these courts. Also, we have waived any right to which we may be entitled on account of
residence or domicile. In any action based upon the Notes in any federal court in the Borough of Manhattan, The City of New York or in any competent court in Mexico we have waived irrevocably any immunity from jurisdiction to which we might
otherwise be entitled, including, to the extent applicable:



| |  |  | sovereign immunity under the Immunities Act;
| | - |  | --------------------------------------------



| |  |  | any other applicable law relating to sovereign immunity; and
| | - |  | ------------------------------------------------------------



| |  |  | immunity from prejudgment attachment, post-judgment attachment and execution.
| | - |  | -----------------------------------------------------------------------------

Redemption

Neither holders of the Notes, nor the trustee, nor any other person can require us to repurchase the Notes or
make mandatory redemption or sinking fund payments on the Notes. The Notes of any series may be redeemable, in whole or in part, at our option, in accordance with the terms of the relevant supplemental indenture.

Concerning the Insured Notes

As of December 31,
2004, we had the following series of insured Notes outstanding:



| |  |  | The 6.30% notes due 2010 issued under the senior indenture as supplemented by the First 6.30% Note Supplemental Indenture between us, Ambac and JPMorgan Chase Bank, N.A., as fiscal
agent and trustee, dated December 1, 1998;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The 6.550% notes due 2008 issued under the senior indenture as supplemented by the Second 6.550% Note Supplemental Indenture between us, Ambac and JPMorgan Chase Bank, N.A., as
fiscal agent and trustee, dated February 25, 1999;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | The 7.33% notes due 2012 issued under the senior indenture as supplemented by the Third 7.33% Note Supplemental Indenture between us, MBIA and JPMorgan Chase Bank, N.A., as fiscal
agent and trustee, dated July 27, 1999; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The 7.80% notes due 2013 issued under the senior indenture as supplemented by the Fourth 7.80% Note Supplemental Indenture between us, MBIA and JPMorgan Chase Bank, N.A., as fiscal
agent and trustee, dated February 10, 2000.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Each of the foregoing series of our insured notes was redeemed and paid in
full by us on June 27, 2005 in accordance with the terms thereof. Of these notes, the 6.550% notes due 2008 and the 6.30% notes due 2010 were insured by Ambac, and the 7.33% notes due 2012 and the 7.80% notes due 2013 were insured by MBIA.
Ambac issued and delivered to the trustee a financial guaranty insurance policy for the benefit of the holders of each of the series of notes which it insured. Similarly, MBIA issued and delivered to the trustee a financial guaranty insurance policy
for the benefit of the holders of the series of notes which it insured. We refer to these policies as the note insurance policies. Under each note insurance policy, MBIA or Ambac, as applicable, unconditionally and irrevocably guarantees
full, complete and timely payment of:



| |  |  | scheduled interest payments for the series of Notes that it insures; scheduled interest payments means, with respect to any series of Notes, scheduled payments of
interest accrued on amounts of principal outstanding under those Notes, and any additional amounts as a result of tax or withholding on the payment that we are required to pay in respect of those scheduled payments of principal or interest;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | originally scheduled principal payments for that series of Notes, and
| | - |  | ---------------------------------------------------------------------



| |  |  | the portion of any payment representing principal and/or interest on that series of Notes which subsequently is avoided in whole or in part as a preference payment under applicable
law.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, in connection with each series of insured Notes, we and MBIA or Ambac, as applicable, entered into an
insurance and reimbursement agreement. We refer to these agreements as the insurance agreements. In each of these agreements, we agreed to reimburse, with interest, the relevant insurer for amounts it paid for claims made under its note
insurance policy. Each also sets forth the insurers rights with respect to the relevant series of insured Notes.

Redemption

On June 27, 2005, we redeemed and paid in full the entire outstanding principal amount of our 6.550% notes due 2008, our 6.30%
notes due 2010, our 7.33% notes due 2012 and our 7.80% notes due 2013 in accordance with the terms thereof, at an aggregate redemption price equal to U.S.$1,098.4 million. The redemption price was equal to 100% of the outstanding principal amount of
each series of Notes that were redeemed, plus (i) accrued and unpaid interest thereon to the redemption date, plus (ii) an amount equal to the applicable make-whole premium calculated pursuant to the relevant supplemental indenture. The
aggregate outstanding principal amount of the Notes redeemed was approximately U.S.$994 million.

We funded the payment of the redemption
price with collections from accounts receivable we had previously purchased from PMI Services.

Termination of the Note Insurance
Policy

The note insurance policies and the obligations of the insurer under those policies terminate upon the expiration of the
term of the relevant note insurance policy. The term of the note insurance policy means the period from and including the date of issuance of the note insurance policy to and including the later to occur of:

(1) the earlier to occur of the dates on which:

(a) all the Notes of the relevant series have been redeemed in accordance with the terms of the applicable indenture; and



66

##### Table of Contents

(b) all scheduled payments of principal and accrued interest, excluding additional
amounts, have been paid or deemed to be paid in respect of those Notes under the applicable indenture, and

(2) the
expiration of the period, if any, during which any scheduled payment of principal and accrued interest could be avoided under any applicable bankruptcy, insolvency, receivership, or similar law.

However, if an insolvency proceeding by or against us exists during that period, then the note insurance policy and the insurers obligations under
that policy terminate on the date of the conclusion or dismissal of that insolvency proceeding without continuing jurisdiction by the court. Further, if the holders of insured Notes are required to return any avoided payment as a result of that
insolvency proceeding, then the relevant note insurance policy terminate on the date on which the insurer, through its insurer fiscal agent, has made all payments required to be made under the terms of that note insurance policy in respect of all
avoided payments.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should
be read in conjunction with our audited financial statements as well as PEMEXs consolidated financial statements in the annual report of Petróleos Mexicanos for the year ended December 31, 2004 and the annual report of Petróleos
Mexicanos for the year ended December 31, 2005 as of the date filed, which are incorporated herein by reference.

Overview

Pemex Finance is a special purpose financing vehicle. We were formed as part of a program established to finance PEMEXs capital expenditures. Our
business consists of:



| |  |  | applying the proceeds of debt, together with other funds available to us from time to time (including collections on purchased receivables and capital contributions, for example)
to:
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | service our outstanding debt; and
| | - |  | ---------------------------------



| |  |  | acquire all of the right, title and interest in and to the eligible receivables of designated customers which are generated through exports of Maya crude oil (or under limited
circumstances, crude oil other than Maya crude oil); and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | issuing unsecured debt.
| | - |  | -----------------------

Our ability to meet our
obligations in respect of our outstanding Indebtedness, including the Notes, depends on a number of variables, including:



| |  |  | compliance by PEP and PMI with their obligations under the transaction documents;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | the ability of PEMEX, operating through PMI and PEP, to generate sufficient eligible receivables of designated customers; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | the continued financial capability of the designated customers.

See
Item 4. Information on the CompanyDescription of BusinessPEMEXs Customers and Receivables.

The market
for crude oil is subject to price volatility and our business and financial condition depend to a large degree on the international prices for crude oil. Historically, the monthly weighted average price of the crude oil that PEMEX exports has
fluctuated from a ten-year low of U.S.$7.67 per barrel in December 1998 to a high of U.S.$61.10 per barrel in May 2006. On June 27, 2006, the spot price for the PEMEX crude oil basket was an estimated U.S.$56.28 per barrel.

PEMEXs crude oil exports to the designated customers are largely comprised of Maya crude oil, which is particularly vulnerable to fluctuations in
international crude oil prices. Because Maya crude oil is a heavy sour crude oil with a smaller, more concentrated market, it is more susceptible to drops in international crude oil demand. In addition, when prices of lighter crude oils decrease,
Maya crude oil becomes less competitive because it costs more to refine it.

In addition, Mexico is the sole owner of PEMEX and the Mexican
Government closely regulates and supervises its operations. Mexican Government intervention could have an adverse effect on the operations of PEMEX, PEP or PMI, which could in turn affect our ability to operate. For instance, if the Mexican
Government were to cause PEP to reduce production or limit future capital expenditures, this could reduce PMIs ability to generate the necessary flow of receivables to support our payments under our indebtedness.

##### Table of Contents

The length of the period from the date on which we transfer to PMI Services and PMI Services transfers to
PMI the purchase price for a future eligible receivable to the date on which that receivable is generated is directly related to:



| |  |  | international prices for crude oil,
| | - |  | -----------------------------------



| |  |  | volumes of crude oil exported to designated customers,
| | - |  | ------------------------------------------------------



| |  |  | the frequency of shipments, and
| | - |  | -------------------------------



| |  |  | the amount of future receivables we already own.
| | - |  | ------------------------------------------------

The
receivables purchase agreement does not create any requirements for volumes of crude oil exports. Designated customers are generally required to make full payment on standard 30 day payment terms.

An increase in international prices for crude oil which is not offset by a decrease in the frequency of shipments and/or in the volume of crude oil sold
to designated customers will reduce the length of the period between our payment of the purchase price for an eligible receivable and our recovery of these funds through payments by the designated customers. Conversely, a decrease in international
prices for crude oil which is not offset by an increase in the frequency of shipments and/or the volume of crude oil sold to designated customers will increase the length of the period between our payment of the purchase price for the eligible
receivable and our recovery of these funds through payments by the designated customers.

Taxation of Pemex Finance

The Cayman Islands currently impose no income, corporation or capital gains tax and no estate duty, inheritance tax or gift tax.
The only government charge payable by us in the Cayman Islands is an annual registration fee of U.S.$573.17 calculated on the basis of the nominal amount of our authorized share capital. A stamp duty will be payable on certain documents that are
executed in or brought to the Cayman Islands.

Basis of Presentation

The U.S. dollar is our functional currency and most of our transactions are denominated in U.S. dollars.

The following discussion refers to amounts stated on the basis of IFRS and should be read in conjunction with the audited financial statements included
elsewhere in this annual report. Although there are a number of differences between IFRS and U.S. GAAP, application of U.S. GAAP would not have produced differences with respect to our shareholders equity and net income. However, a difference
would have been produced with respect to the balance sheet presentation of our borrowings and unearned discount. For more information, see Note 11 to our financial statements in Item 18.

the outstanding principal amount of each series of Notes that were redeemed, plus (i) accrued and unpaid interest thereon to the redemption date, plus (ii) an amount equal to the applicable make-whole premium calculated pursuant to the
relevant supplemental indenture. The aggregate outstanding principal amount of the Notes redeemed was approximately U.S.$994 million. In addition, on June 27, 2005, after the payment of the redemption price with respect to our 6.550% notes due
2008, our 6.30% notes due 2010, our 7.33% notes due 2012 and our 7.80% notes due 2013, we prepaid U.S.$550 million (and accrued and unpaid interest thereon to the date of prepayment) to Petróleos Mexicanos under the subordinated note dated
January 1, 2002. On August 12, 2005, we reborrowed U.S.$70 million from Petróleos Mexicanos under this subordinated note in order to satisfy the required debt to equity ratio specified in the transaction documents.

Due to our limited business, our revenue sources in the future are unlikely to change.

Purchased accounts receivable include: (1) future eligible receivables (i.e., accounts receivable which have not been generated as of the date of
the corresponding balance sheet) and (2) current eligible receivables (i.e., accounts receivable which have been generated as of the date of the corresponding balance sheet).

We record revenue from the discount on purchased accounts receivable for a period as income when earned as follows:



| |  |  | discounts on future (ungenerated) purchased accounts receivable are determined by applying the relevant discount rate to the daily balance of future eligible receivables;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | discounts on current purchased accounts receivable are determined by applying the relevant discount rate to the invoice amount of the receivable based on the number of days from
generation until that current eligible receivable becomes due and payable by the designated customer; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any unearned discount at the financial statements date is presented netting the current purchased accounts receivable.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

During the period from January 1, 2005 to December 31, 2005 the discount rate applied to the purchase of eligible receivables increased from
9.21259% to 9.59709%. During the period from January 1, 2004 to December 31, 2004 the discount rate applied to the purchase of eligible receivables increased from 9.11165% to 9.21259% and during the period from January 1, 2003 to
December 31, 2003 the discount rate applied to the purchase of eligible receivables increased from 9.05408% to 9.11165%. In each case the change in the discount rate was as a result of the impact on the calculation of the discount rate of the
varying interest rates on our floating rate notes.

The discount rate applied to the eligible receivables purchased during these periods is
equal to the weighted average of the yield of our outstanding Indebtedness on the purchase date for those eligible receivables plus the specified basis points. During these periods the specified basis points equaled 50 basis points. The
total amount of the discount on each purchased eligible receivable (i.e., the total revenue generated by each purchased eligible receivable) is determined by discounting the invoice amount of that eligible receivable for the period from the date on
which the purchase price for that eligible receivable was paid to PMI to the day on which the purchased eligible receivable is due from the designated customer.

Revenues decreased by 29.05% from U.S.$428.8 million in 2004 to U.S.$304.2 million in 2005. The decrease
in income from discounts on current purchased eligible receivables was largely due to the fact there was an increase in the Mexican crude oil basket price in 2005 compared to 2004, resulting in a shorter calculation period for current discount
calculations compared to 2004. This is reflected in the 27.69% decrease in income from discounts on current purchased eligible receivables in 2004 from U.S.$455.7 million to U.S.$329.5 million in 2005.

Revenues decreased by 6.2% from U.S.$456.7 million in 2003 to U.S.$428.8 million in 2004. The decrease in income from discounts on current purchased
eligible receivables was largely due to the fact there was an increase in the volume of crude oil exported and an increase in the Mexican crude oil basket price in 2004 compared to 2003, resulting in a shorter calculation period for current discount
calculations compared to 2003. This is reflected in the 6.3% decrease in income from discounts on current purchased eligible receivables in 2003 from U.S.$486.3 million to U.S.$455.7 million in 2004.

Under the receivables purchase agreement, eligible receivables of designated customers are purchased in the order they are generated: in other words, in
the order the crude oil is shipped. The amount of current eligible receivables owing from any designated customer is not subject to any concentration limit and is entirely dependent on (1) the volumes of crude oil those designated customers
purchased from PMI during the preceding 30 days and (2) the price PMI charges for each of those sales. Accordingly, the revenues derived from discounts on purchased receivables paid by any designated customer or any group of designated
customers is subject to continuous change.

Under the receivables purchase agreement, eligible receivables which have been generated by PMI
must be payable in full within 30 days, and they currently are paid within that period. The limit may be extended to any longer period of up to 90 days if that becomes the prevailing practice in the international oil business. Under the receivables
purchase agreement, PMI is not required to generate any set amount of eligible receivables within any specified period.

The 287.51%
increase in interest income from highly liquid temporary investments in 2005 over 2004 was primarily due to an increase in our interest income from the investment of funds in the liquidity account. Such increase in interest income in turn was
principally due to our increased retention of funds in the liquidity account for the purpose of paying for the redemption of our 6.550% notes due 2008, our 6.30% notes due 2010, our 7.33% notes due 2012 and our 7.80% notes due 2013 on June 27,
2005 and the prepayment of our subordinated debt to Petróleos Mexicanos on the same date, as well as a general increase in interest rates in the United States, which was reflected in the interest rates of the securities in which we are
allowed to invest liquidity account funds.

The 39.9% increase in interest income from highly liquid temporary investments in 2004 over
2003 was primarily due to an increase in our interest income from the investment of funds in the liquidity account. Such increase in interest income in turn was largely due to a general increase in interest rates in the United States, which was
reflected in the interest rates of the securities in which we are allowed to invest liquidity account funds.

Interest Expenses and
Make-whole Premium

Interest expenses consist of interest accrued on our outstanding debt as well as the premiums payable to MBIA and
Ambac with respect to the insured series of Notes and amortization of debt issuance costs.

Interest expense decreased from U.S.$414.3
million in 2004 to U.S.$317.9 million in 2005, a decrease of 23.3%. The decrease in interest expense was primarily due to the redemption of 4 series of our notes in 2005 (however, a make-whole premium of U.S.$96.4 million was paid in such
redemption) and the maturity of certain of our notes, which reduced the amount of debt that we service.

General and Administrative Expenses

General and administrative expenses include primarily the expenses incurred in connection with the issuance of debt as well as in connection with services
rendered to us by PMI and certain of its affiliates, and include accounting, legal, rating, bank administration, listing and other fees and expenses associated with the performance of our obligations under the transaction documents as well as, to a
lesser degree, expenses incurred in connection with services rendered to us by PMI and certain of its affiliates.

General and
administrative expenses increased to U.S.$2.78 million in 2005 from U.S.$1.58 million in 2004. The 76.21% increase was largely due to increases in legal and administrative expenses. General and administrative expenses increased to U.S.$1.58 million
in 2004 from U.S.$1.55 million in 2003. The 1.89% increase was largely due to increases in legal and administrative expenses.

Eligible
receivables we purchase under the receivables purchase agreement are serviced, managed, administered and collected by PMI acting as servicer under the servicing and collection agency agreement. Fees paid to the servicer amounted to U.S.$0.41 million
in 2005, U.S.$0.39 million in 2004 and U.S.$0.39 million in 2003.

Taxes

We had no tax expense during 2005, 2004 or 2003.

Net Income

Net income (loss) decreased from U.S.$16.13 million in 2004 to U.S.$(100.42) million in 2005, a decrease of
722.43%. Net income decreased from U.S.$17.07 million in 2003 to U.S.$16.13 million in 2004, a decrease of 5.4%.

Liquidity and Capital Resources

Our sources of liquidity are collections on purchased receivables, the proceeds of our debt issuances and additional capital
contributions. The collections on purchased receivables are determined by the volume of eligible receivables generated, which is in turn affected by the volumes of crude oil exported and by international oil prices. We believe that our working
capital is sufficient for our present requirements.

We have issued the following senior and subordinated debt:



| |  |  | On December 7, 1998, we received U.S.$250 million in the form of subordinated debt issued to Petróleos Mexicanos. On December 14, 1998, we issued the 1998 notes, in
an aggregate principal amount of U.S.$1.5 billion.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On February 25, 1999, we issued the February 1999 notes, in an aggregate principal amount of U.S.$1.0 billion. On the same date, we also issued the February 1999 floating rate
notes in an aggregate principal amount of U.S.$100 million. Prior to issuing the February 1999 notes and the February 1999 floating rate notes, on February 24, 1999, we received U.S.$125 million in the form of subordinated debt issued to
Petróleos Mexicanos.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On July 27, 1999, we issued the July 1999 notes, in aggregate principal amount of U.S.$1.275 billion. On the same date, we also issued additional fixed rate notes having an
aggregate principal amount of U.S.$50 million and two series of floating rate notes having an aggregate principal amount of U.S.$125 million. On July 23, 1999, we received U.S.$204 million in the form of subordinated debt issued to
Petróleos Mexicanos.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On February 10, 2000, we issued the February 2000 notes, in aggregate principal amount of U.S.$950 million. On February 8, 2000, we received U.S.$136 million in the form
of subordinated debt issued to Petróleos Mexicanos.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On January 1, 2002, we issued a new subordinated note to Petróleos Mexicanos for U.S.$714.75 million consolidating the four subordinated notes we had previously
issued to Petróleos Mexicanos.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We had U.S.$2.57 billion in borrowings as of December 31, 2005 (including
borrowings under the Notes, as well as the subordinated note issued to Petróleos Mexicanos). For information on the maturity profile of our borrowings, see Item 11. Quantitative and Qualitative Disclosures About Market Risk.

On June 27, 2005, we redeemed and paid in full the entire outstanding principal amount of our 6.550% notes due 2008, our 6.30% notes
due 2010, our 7.33% notes due 2012 and our 7.80% notes due 2013 in accordance with the terms thereof, at an aggregate redemption price equal to U.S.$1,098.4 million. The aggregate outstanding principal amount of the Notes redeemed was approximately
U.S.$994 million. In addition, on June 27, 2005, after the payment of the redemption price with respect to our 6.550% notes due 2008, our 6.30% notes due 2010, our 7.33% notes due 2012 and our 7.80% notes due 2013, we prepaid U.S.$550 million
(and accrued and unpaid interest thereon to the date of prepayment) to Petróleos Mexicanos under the subordinated note dated January 1, 2002. We funded the payment of the redemption price, as well as the prepayment of our subordinated
debt, with collections from accounts receivable we had previously purchased from PMI Services. On August 12, 2005, we reborrowed U.S.$70 million from Petróleos Mexicanos under the subordinated note dated January 1, 2002.

PEPs and PMIs ability to generate eligible receivables of designated customers is dependent upon, among other factors, international
prices for crude oil, volumes of crude oil exported to designated customers and the frequency of shipments. Either of (1) a reduction in international oil prices which is not offset by an increase in the frequency of shipments and/or the volume
of crude oil sold to eligible customers or (2) the failure of designated customers to make timely payments with respect to purchased receivables, as well as increasing the length of the period between our payment of the purchase price for the
eligible receivable and our recovery of these funds through payments by the designated customers could result in a decrease in the level of collections, which would in turn affect our liquidity.

During 2005, 2004 and 2003 we used U.S.$16.8 billion, U.S.$14.7 billion and U.S.$11.3 billion, respectively, to purchase accounts receivable from PMI
Services. We funded these purchases with collections from purchased accounts receivable received during the relevant period.

The time required to generate
our future purchased receivables at any given date is a function of many factors, including primarily the price of Maya crude oil, the volume of Maya crude oil PMI sells to the designated customers and the amount of purchased receivables which
remain to be generated. Changes in any of these factors during the period could increase or decrease the time required.

When we receive
funds from collections in respect of purchased receivables we either:



| |  |  | apply the funds to service or refinance existing Indebtedness or for other corporate purposes permitted by the fiscal agency agreement, or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | transfer the funds to PMI Services, who in turn transfer them to PMI to purchase additional eligible receivables of designated customers on a daily basis.

We have no
off-balance sheet arrangements of the type that we are required to disclose under Item 5.E of Form 20-F.

|Item 7. | Major Shareholders and Related Party Transactions.
|------- | --------------------------------------------------

Pursuant to the declaration of trust establishing the Pemex Finance Trust, a charitable trust created under the laws of the Cayman Islands, all of our outstanding shares are owned by BNP Paribas Bank as trustee for the Pemex Finance Trust.
Our authorized share capital consists of 1,000 ordinary shares, U.S.$1.00 par value per share, all of which have been issued.

Pursuant to
an agreement dated July 1, 2005 between Petróleos Mexicanos and BNP Paribas Bank, the latter granted Petróleos Mexicanos an option to purchase all the shares owned by BNP Paribas Bank on or after we repay all of our indebtedness.
In the event Petróleos Mexicanos elects to exercise this option, the applicable purchase price would be U.S.$10 per share.

Since
our inception there have been no, and there are no proposed, material transactions in which any director, officer or our shareholder is a party. None of our directors, officers, or associates of any of our directors or officers have been indebted to
us at any time since our inception.

We consider Petróleos Mexicanos to be a related party, as we purchase all the current eligible
receivables and rights to future (ungenerated) eligible receivables from PMI, which is an indirect wholly-owned subsidiary of Petróleos Mexicanos. During 2005 we purchased U.S.$16.8 billion of such eligible receivables and during 2004 we
purchased U.S.$14.7 billion of such eligible receivables. At December 31, 2004, we had subordinated debt outstanding from Petróleos Mexicanos of U.S.$725.66 million. On June 27, 2005, we elected to prepay U.S.$550 million (and
accrued and unpaid interest thereon to the date of prepayment) of our subordinated debt to Petróleos Mexicanos in accordance with the terms thereof. On August 12, 2005, we reborrowed U.S.$70 million from Petróleos Mexicanos under
this subordinated debt in order to satisfy the required debt to equity ratio specified in the transaction documents. At December 31, 2005, we had subordinated debt outstanding from Petróleos Mexicanos of U.S.$238.44 million.



|Item 8. | Financial Information.
|------- | ----------------------

Item 18.Financial Statements.

There is no litigation or governmental proceeding pending or, to our knowledge,
threatened against us that, if adversely determined, would have a significant effect on our financial position or profitability. In addition, to our knowledge, there is no litigation pending or threatened against PMI Services that, if adversely
determined, would have a significant effect on its financial position or profitability.

MEMORANDUM AND ARTICLES OF ASSOCIATION

Register

We are a limited liability company
incorporated in the Cayman Islands under the Companies Law (2003 Revision, as amended), under company registration number 85919. We registered and filed our Memorandum and Articles of Association with the Registrar of Companies on
November 18th, 1998. There has been no subsequent amendment to our Memorandum and Articles of Association.

Objects and Purposes

Our Memorandum of Association grants us full power and authority to carry out any object not prohibited by law. Nevertheless, the sole object for which we
are established is the business of banking and finance (outside the Cayman Islands) through acquiring eligible receivables and incurring indebtedness.

Directors

Directors may vote on a proposal, arrangement or contract in which they are interested. However, interested
directors must declare the nature of their interest at a directors meeting. If the interested directors declare their interest, their votes are counted and they are counted in the quorum of such meeting.

The directors may exercise our powers including to borrow money and issue debt securities.

Directors are not required to own shares.

Rights and
Obligations of Shareholders

Dividends

Shareholders may declare dividends in a general meeting but the dividends cannot exceed the amount recommended by the directors. The directors may pay the shareholders interim dividends and may, before recommending
any dividend, set aside reserves out of profits. The directors can invest these reserves in their discretion so long as the reserves are not being used for these purposes.

Dividends may be paid in cash or in kind but may only be paid out of profits or, subject to the restrictions of Cayman Islands law, a share premium
account.

Voting Rights

Votes may be cast at a general meeting by a show of hands or by a poll. On a vote by a show of hands, each shareholder or shareholder represented by proxy has one vote. On a vote by a poll, each shareholder or shareholder represented by
proxy has one vote for each share owned.

Directors are elected by the shareholders at general meetings. Shareholders are not entitled to
vote at a general meeting unless calls or other amounts payable on their shares have been paid. In lieu of voting on a matter at a general meeting, the shareholders entitled to vote on that matter may adopt the matter by signing a resolution.

Redemption

We
may issue shares which are redeemable by us or by our shareholders. The amount payable on each share in a redemption is its fair value as determined by the directors.

Where we have agreed to purchase any share from a shareholder, we will give notice to the other shareholders, if any, specifying the number and class of shares to be purchased, the name and address of the seller, the
price to be paid for the shares and the portion (if any) of that price which is being paid out of capital. The notice will also indicate a date on which the purchase is to be effected and will invite shareholders other than the seller, if any, to
object to the purchase before that date.

Shareholder Rights Upon Liquidation

If we are liquidated, the liquidator may (in accordance with a shareholder resolution):



| |  |  | set a fair value on our assets, divide all or part of our assets among the shareholders and determine how the assets will be divided among shareholders or classes of shareholders;
and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | vest all or part of our assets in trustees.
| | - |  | -------------------------------------------

Shareholders
will not be compelled to accept any securities on which there is a liability.

Calls on Shares

Directors may make calls on the shareholders with respect to any amounts unpaid on their shares. Each shareholder shall pay to the company the amounts
called on such shares.

Change to Rights of Shareholders

Shareholders may change the rights of their class of shares by:



| |  |  | getting the written consent of three-fourths of the shareholders of that class; or
| | - |  | ----------------------------------------------------------------------------------



| |  |  | passing a special resolution at a meeting of the shareholders of that class.
| | - |  | ----------------------------------------------------------------------------

We have only one class of shares. There are no limitations on the rights to own shares.

General Meetings

A general meeting may be convened:



| |  |  | by the directors at any time;
| | - |  | -----------------------------



| |  |  | by the sole shareholder by written request; or
| | - |  | ----------------------------------------------



| |  |  | by any two shareholders, should there be more than one shareholder, in the same manner as the directors convene general meetings.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------

Notice of a general meeting is given to all shareholders.

All business carried out at a general meeting is considered special business except:



| |  |  | sanctioning a dividend;
| | - |  | -----------------------



| |  |  | consideration of the accounts, balance sheets, and ordinary report of the directors and auditors;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | appointment and removal of directors; and
| | - |  | -----------------------------------------



| |  |  | fixing of payment of the auditors.
| | - |  | ----------------------------------

Shareholder consent
is required to carry out special business at a meeting unless notice of the special business is given in the notice of the meeting. A quorum of shareholders is required to be present at any meeting in order to carry out business. Any two
shareholders or one shareholder holding a majority of the shares who are present in person or represented by proxy is a quorum.

There is
no requirement under Cayman Islands law to convene an annual meeting or to convene any general meeting of the shareholders. The directors are permitted to designate any general meeting of shareholders as an annual general meeting.

Changes in Capital

We may increase our share capital
by ordinary resolution. The new shares will be subject to all of the provisions to which the original shares are subject.



82

##### Table of Contents

We may also by ordinary resolution:



| |  |  | consolidate and divide all or any of our share capital into shares of a larger amount;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | sub-divide existing shares into shares of a smaller amount, subject to the provisions of Section 13 of the Companies Law (2003 Revision, as amended) of the Cayman Islands; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | cancel any shares which, at the date of the resolution, are not held or agreed to be held by any person.
| | - |  | --------------------------------------------------------------------------------------------------------

We may reduce our share capital and any capital redemption reserve by special resolution.

EXCHANGE CONTROLS AND OTHER LIMITATIONS AFFECTING SECURITY HOLDERS

There are:

(a) no governmental laws, decrees or regulations in Cayman Islands that restrict the export or import of capital, including
dividend and other payments to non-resident holders to the Cayman Islands, and

(b) no limitations on the right of
nonresident or foreign owners imposed by Cayman Island law or the Memorandum and Articles of Association of Pemex Finance to hold or vote our shares.

TAXATION

The following is a summary of certain Cayman Islands and United States federal income tax
considerations that may be relevant to the purchase, ownership, and disposition of the Notes. This summary does not describe any tax consequences arising under the laws of any state, locality or taxing jurisdiction other than the United States and
the Cayman Islands.

This summary is based on the tax laws of the Cayman Islands and the United States as in effect on the date of this
annual report, as well as regulations, rulings and decisions of the Cayman Islands and the United States available on or before the date of this annual report and now in effect. All of these laws, regulations, rulings and decisions are subject to
change, which could apply retroactively and cause statements in this summary to no longer be true. There is no reciprocal tax treaty between the Cayman Islands and the United States.

Cayman Islands Taxation

Payments of principal and interest on the Notes will not be subject
to taxation in the Cayman Islands. No withholding is required on these payments to the holders of the Notes, and gains derived from the sale of Notes will not be subject to Cayman Islands income or corporation tax.

U.S. Federal Income Taxation

This summary of
certain United States federal income tax considerations deals principally with U.S. holders who will hold Notes as capital assets and whose functional currency is the U.S. dollar. A U.S. holder means a beneficial owner of a Note who is a
citizen or resident of the United States or a U.S. domestic corporation or will otherwise be subject to United States federal income taxation on a net income basis in respect of the Notes.

This summary is not a comprehensive description of all of the tax considerations that may be relevant to a U.S. holders decision to purchase, hold
or dispose of Notes and generally does not address the tax treatment of U.S. holders that may be subject to special tax rules, such as banks, tax-exempt entities, insurance companies, dealers in securities or currencies, traders in securities
electing to mark to market or persons that will hold Notes as a position in a straddle or conversion transaction, or as part of a synthetic security or other integrated financial transaction.

##### Table of Contents

U.S. Holders

Interest and Additional Amounts

A
U.S. holder will treat the gross amount of interest (including any additional amounts paid to compensate the U.S. holder for amounts withheld or deducted from payments) paid in respect of the Notes as ordinary interest income at the time that
it is paid or accrued, in accordance with the U.S. holders method of accounting for United States federal income tax purposes.

Disposition of the Notes.

In general a U.S. holder of a Note will recognize gain or loss upon the sale, exchange,
redemption, retirement or other disposition of the Note equal to the difference between the amount realized on the disposition (to the extent such amount does not represent accrued but unpaid interest, which will be taxable as ordinary income) and
the U.S. holders adjusted basis in the Note. Initially, the U.S. holders adjusted basis in the Note generally will equal the cost of the Note to the U.S. holder, and will increase by amounts included in income by the U.S. holder under
the rules governing market discount, discussed below, and will decrease by the amount of amortized premium, discussed below.

The gain or
loss on a disposition of a Note by a U.S. holder generally will be capital gain or loss and will be long-term capital gain or loss if the U.S. holder holds the Note for more than one year prior to disposition. The net amount of long-term capital
gain recognized by an individual holder before January 1, 2011 generally is subject to taxation at reduced rate of tax.

Premium

A U.S. holder that purchases a Note at a cost greater than the Notes principal amount will be considered to have purchased the
Note at a premium and may elect to amortize the premium as an offset to interest income, using a constant yield method, over the Notes remaining term. This election generally applies to all debt instruments that the U.S. holder holds at the
time of the election, as well as any debt instruments held during or after the taxable year for which the election is made. In addition, the U.S. holder may not revoke the election without the consent of the United States Internal Revenue Service. A
U.S. holder electing to amortize the premium will be required to reduce its tax basis in the Note by the amount of the premium amortized during its holding period. If a U.S. holder with a premium does not elect to amortize the premium, the amount of
the premium will be included in the U.S. holders tax basis in the Note, and therefore, if the Note is held to maturity, will generally give rise to capital loss when the Note matures.

Market Discount

A U.S. holder that
purchases a Note at a cost that is lower than its principal amount will be considered to have purchased a Note with a market discount in the hands of such U.S. holder (unless the amount of such excess is less that a specified de minimis
amount, in which case the Note will not be considered to have a market discount). If a U.S. holder acquired a Note with market discount, any gain realized by the U.S. Holder on the disposition of the Note generally will be treated as ordinary
interest income to the extent of the market discount that accrued on the Note during the U.S. holders holding period. In addition, a U.S. holder may be required to defer the deduction of a portion of the interest paid on any indebtedness that
it incurred or continued to purchase or carry the Note. In general, market discount will be treated as accruing ratably over the term of the Note, or at the U.S. holders election, under a constant yield method.

A U.S. holder may elect to include market discount in gross income currently as it accrues (on either a ratable or constant yield basis), in lieu of
treating a portion of any gain realized on a sale of the Note as ordinary income, in which case the interest deduction deferral rule described above will not apply. If made, this election applies to all market discount debt instruments that the U.S.
holder acquires on or after the first day of the first taxable year to which the election applies and may not be revoked without the consent of the United States Internal Revenue Service.

##### Table of Contents

Non-U.S. Holders

Subject to the discussion of backup withholding below, a holder of Notes who is, with respect to the United States a foreign corporation or nonresident
alien individual (a non-U.S. holder), will not be subject to United States federal income tax, including withholding taxes, on any payments of interest on the Notes, unless the income from payments on the Notes is effectively
connected with his or her conduct of a trade or business in the United States.

Subject to the discussion of backup withholding below, a
non-U.S. holder also will not be subject to United States federal income tax on any capital gain realized on the sale or exchange of Notes, unless:

(i) that gain is effectively connected with its conduct of a trade or business in the United States; or

(ii) an individual non-U.S. holder who is present in the United States for 183 days or more in the taxable year of the sale and
meets certain other conditions.

In addition, if individual holders at the time of their deaths are nonresident aliens, any Notes held by
such individuals will not be subject to United States federal estate tax.

Backup Withholding and Information Reporting

The trustee may be required to file information returns with the United States Internal Revenue Service with respect to payments
made to some U.S. holders of Notes. In addition, a U.S. holder may be subject to a backup withholding tax in respect of some payments if he or she does not provide his or her taxpayer identification number to the trustee or otherwise comply
with applicable requirements of the backup withholding rules. In order to avoid the information reporting requirements and backup withholding tax, a non-U.S. holder may be required to comply with applicable certification procedures to establish that
he or she is not a U.S. holder. Any amounts withheld under the backup withholding rules are not an additional tax and may be refunded or credited against his or her United States federal income tax liability, if any, provided such holder
furnishes required information to the United States Internal Revenue Service.

DOCUMENTS ON DISPLAY

We are subject to the informational requirements of the Securities Exchange Act of 1934, as amended. In accordance with these requirements, we file
reports, including annual reports on Form 20-F, and other information with the SEC. These materials, including this annual report and the exhibits thereto, may be inspected and copied (at prescribed rates) at the SECs public reference room at
100 F Street, N.E., Washington, D.C. 20549. Please call the SEC at 1-800-SEC-0330 for further information on the public reference room. The SEC also maintains a web site at http://www.sec.gov that contains reports, proxy statements and other
filings we make electronically with the SEC. In addition, copies of the receivables purchase agreement, fiscal paying agency agreement, servicing and collection agency agreement and the letter agreement are available for inspection at the principal
office of the fiscal agent in the City of New York, which is presently located at JPMorgan Chase Bank, N.A., Capital Markets Fiduciary Services, 4 New York Plaza, 15thFloor, New York, NY 10004.



|Item 11. | Quantitative and Qualitative Disclosures About Market Risk.
|-------- | -----------------------------------------------------------

The following discussion includes forward-looking statements that involve risk and uncertainties. Actual results could differ materially from those projected in the forward-looking statements.

The following table summarizes the financial instruments we held at December 31, 2005 which are sensitive to changes in interest rates. We do not
use any derivative instruments to manage this primary market exposure. In the normal course of business, we also face risks that are non-financial or non-quantifiable. Such risks include credit risk and are not represented in the following table.
For more information on credit risk, see Note 3 to our financial statements in Item 18. Further, since all of our debt is dollar denominated, we are not subject to material foreign exchange rate risk.

|-------- | -----------------------

We carried out an
evaluation under the supervision and with the participation of our management, including our president, who performs functions similar to those of a principal executive officer and principal financial officer, of the effectiveness of the design and
operation of our disclosure controls and procedures as of December 31, 2005. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention
or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our president concluded that the
disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized
and reported within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our president, as appropriate to allow timely decisions regarding disclosure.

There has been no change in our internal control over financial reporting during 2005 that has materially affected, or is reasonably likely to materially
affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Mexico City, April 21, 2006

To the Shareholder and Board of Directors of

Pemex Finance Limited

We have audited the
accompanying balance sheets of Pemex Finance Limited (the Company) as of December 31, 2005 and 2004, and the related statements of income, of changes in shareholders equity and of cash flows for the three years then ended, all
expressed in US dollars. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the International Standards of Auditing and the standards of Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well evaluating the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the accompanying financial statements present fairly, in all material respects, the financial
position of Pemex Finance Limited as of December 31, 2005 and 2004, the results of its operations and cash flows for the years ended December 31, 2005, 2004 and 2003, in accordance with International Financial Reporting Standards (IFRS) as
issued by the International Accounting Standards Board.

As discussed in Note 11, the Companys financial statements are prepared in accordance with
IFRS. As of December 31, 2005 and 2004 and for the years ended December 31, 2005, 2004 and 2003, the application of Accounting Principles Generally Accepted in the United States would not have produced differences with respect to the
Companys shareholders equity and the net income, however there are two differences related to the balance sheet presentation.

December 7, 1998. All of the outstanding share capital is owned by BNP Paribas Bank & Trust Cayman Limited (BNP Paribas Bank) as trustee of the Pemex Finance Trust, a charitable trust created under the laws of the Cayman Islands. The
Company is managed by BNP Paribas Bank and has no employees. The Company is a special purpose financing vehicle formed as part of a program established to finance the capital expenditures of Petróleos Mexicanos (PEMEX).

The main objective of the Company is to transact selected financing activities outside the Cayman Islands. The Companys business is limited to the issuance of debt
and the purchase of certain accounts receivable under the Receivables Purchase Agreement (RPA) dated as of December 1, 1998, which is summarized as follows:

Pursuant to terms of the RPA, the Company has the right to purchase from P.M.I. Services B.V. (Services), an indirect wholly-owned subsidiary of PEMEX, and Services has the right to purchase from P.M.I. Comercio Internacional, S. A. de C.
V. (Comercio), a subsidiary of PEMEX, certain current and future accounts receivable (Eligible Receivables) generated or to be generated by the export from Mexico of crude oil to certain designated customers (Designated Customers). Any Eligible
Receivables that are not due and payable when purchased (at the time the purchase price is paid) are purchased at a discount. The amount of the discount is determined by discounting the invoice amount of such Eligible Receivables by a rate equal to
the weighted average yield of the Companys outstanding indebtedness (excluding the subordinated debt to PEMEX) on the day the Company pays the purchase price for such Eligible Receivables to Services, plus the Specified Basis Points (50 basis
points).

On December 14, 1998, PEMEX signed a letter addressed to the Company whereby it agreed to cause Comercio to perform its material obligations
under the RPA, but not the payment of any Eligible Receivables purchased by the Company. Neither PEMEX nor any of its affiliates or subsidiaries in any way guarantees payment of the purchased Receivables and neither PEMEX nor any of its affiliates
or subsidiaries shall be liable for nonpayment of any purchased Receivable by any Designated Customer.

All proceeds received or to be received by the
Company from Designated Customers or from any issuance of debt, including amounts contributed as capital, have been or will be used to purchase current or future Eligible Receivables of Designated Customers from Services, to service or refinance its
existing indebtedness or for general corporate purposes.

On June 20, 2006 the Companys Board of Directors approved the issuance of these
financial statements. Neither The Pemex Finance Trust nor PEMEX are allowed to amend the financial statements after issue.

NOTE 2SIGNIFICANT ACCOUNTING POLICIES:

The following is a summary of the significant accounting policies followed by the Company in
the preparation of the accompanying financial statements:



|a. | Basis of presentation
|-- | ----------------------



| | The financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS). The measurement basis used in preparing these financial statements
is historical basis. The Companys functional and presentation currency is the U.S. dollar.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|b. | Accounts receivable
|-- | --------------------



| | The rights to future (ungenerated) purchased accounts receivable, is equal to the amount paid to Services to purchase Eligible Receivables to be generated by Comercio, approximately
within the following 15 days. As Comercio exports crude oil to the Designated Customers, evidenced by a bill of lading, such amount becomes current purchased accounts receivables.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | Current purchased accounts receivable are originally recorded at fair value to be received from the Designated Customers, pursuant to the terms and conditions agreed with Comercio.
The originally recorded amount may be adjusted pursuant to such terms and conditions and, in such case, the adjusted amount would be the actual amount payable by Designated Customers. All proceeds received from the Designated Customers are applied
to reduce the current purchased accounts receivable. These proceeds are used to purchase from Services new future Eligible Receivables.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | The Designated Customers are normally major oil companies, highly rated by recognized rating agencies and strictly monitored by Comercio with respect to their financial position and
results of operation. The Designated Customers ability to comply with their financial commitments has not historically resulted in delinquencies. However, in the event the Company had objective evidence that it will not be able to collect all
amounts due according to the original terms of receivables, a provision for impairment of accounts receivable would be established.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | As of December 31, 2005 and 2004, current accounts receivable turnover is in average of 30 days.
| | ------------------------------------------------------------------------------------------------



|c. | Revenue recognition
|-- | --------------------



| | Revenue from the discount on purchased accounts receivable is recorded as income when interests are generated as described below:
| | ---------------------------------------------------------------------------------------------------------------------------------

i. Discounts on future (ungenerated) purchased accounts receivable (Eligible Receivables of Designated Customers that have not yet been
generated by Comercio) are determined by applying the relevant discount rate (as determined on the date on which the purchase price for such Eligible Receivables was paid to Services) to the daily balance of future Eligible Receivables as determined
by the purchase date. Such discounts are recorded as income from discount on Purchased Eligible Receivables as earned on a daily basis using the effective interest method.

The effective interest method is a method of calculating the amortized cost of a financial asset and allocating the interest income over
the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts through the expected life of the financial instruments or, when appropriate, a shorter period to the net carrying amount of the
financial assets.

ii. Discounts on current purchased accounts receivable (Eligible Receivables of Designated Customers that
have been generated by Comercio) are determined by applying the relevant discount rate to the corresponding invoice amount based on the number of days elapsed from the purchase day to the payment day. The related discount is recorded as income when
earned during this period using the effective interest method. Any unearned discount at the date of the financial statements is presented netting the current purchased accounts receivable.

iii. The total amount of the discount on each Eligible Receivables (i.e., the total revenue generated by each purchased Eligible
Receivables) is determined by discounting the invoice amount of such Eligible

Amounts in thousands of U.S. dollars



Receivables for the period from the day on which the purchased Eligible Receivables is due from the Designated Customer to the date on which the purchase
price for such Eligible Receivables was paid to Services. As of December 31, 2005 the discount rate for Eligible Receivables purchased was 9.59709% (9.21259% as of December 31, 2004).During 2005 the discount rate applied to
purchase Eligible Receivables fluctuated between a range of 9.21259% and 9.59709% (between 9.10530% and 9.21259% during 2004 and between 9.05408% and 9.11165% during 2003).



|d. | Accounting estimates
|-- | ---------------------

Preparation of financial
statements in conformity with IFRS requires that management make estimates and assumptions that affect the amounts reported of assets and liabilities at the date of the financial statements and the amounts reported of revenues and expenses during
the reported period. Actual results could differ from those estimates.



|e. | Cash and cash equivalents
|-- | --------------------------

The Company considers as
cash equivalents all deposits with original maturities of less than three months.



|f. | Borrowings
|-- | -----------

Borrowings are recognized as the
proceeds received, net of transactions costs incurred. Borrowings are subsequently stated at amortized cost. Borrowings are classified as current liabilities unless the Company has an unconditional right to defer settlement of the liability for at
least 12 months after the balance sheet date.



|g. | Provisions
|-- | -----------

Provisions on the balance sheet are
recognized when the Company has a present legal or constructive obligation as a result of past events; it is more likely than not that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated.
Provisions are not recognized for future operating losses.



|h. | New accounting pronouncements
|-- | ------------------------------

The International
Accounting Standards Board (IASB) issued some interpretations and amendments to published standards effective in 2005, these interpretation and amendments include:



| |  |  | IFRIC 2, Members Shares in Co-operative Entities and Similar Instruments (effective from 1 January 2005).
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | SIC 12 (Amendment), ConsolidationSpecial Purpose Entities (effective from 1 January 2005).
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | IAS 39 (Amendment), Transition and Initial Recognition of Financial Assets and Financial Liabilities (effective from 1 January 2005).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------

The Companys management considers these modifications will not have a significant effect on its financial information.

quantitative information about exposure to risks arising from financial instruments, including specified minimum disclosures about credit risk, liquidity risk and market risk, including sensitivity analysis to market risk. It replaces IAS 30,
Disclosures in the Financial Statements of Banks and Similar Financial Institutions, and disclosure requirements in IAS 32, Financial Instruments: Disclosure and Presentation. It is applicable to all entities that report under IFRS. The amendment to
IAS 1 introduces disclosures about the level of an entitys capital and how it manages capital. The Company is currently evaluating the possible impact that its adoption will have on its financial statements.



|i. | Segment reporting
|-- | ------------------

The Company operates in one
reportable segment of acquiring accounts receivable; therefore no segment disclosure is required. Most of the Companys accounts receivable are related to companies based in the United States, Canada, Aruba and Mexico.



|j. | Reclassifications
|-- | ------------------

Certain periods amounts have
reclassificated to the current presentation.

NOTE 3SIGNIFICANT RISKS:

In 2005, the Company purchased accounts receivable of Designated Customers from the United States, Canada, Aruba and Mexico.

Credit risk with respect to trade receivables is concentrated due to the limited number of customers. Four customers represent 75% and 57% of accounts receivable at
December 31, 2005 and 2004, respectively.

The Company is exposed to concentration of credit risk primarily as a result of holding current and future
purchased accounts receivable and cash equivalents. The Companys cash equivalents are high-quality securities placed with several financial institutions. Current purchased receivables are dispersed among a Designated Customer base of companies
incorporated in the United States, Canada, Aruba and Mexico although the majority are in the United States; and purchased future accounts receivable (to be delivered by Comercio upon generation) represent amounts paid to Comercio on account of
future accounts receivable. Amounts paid on account of future (ungenerated) Eligible Receivables of Designated Customers (to be generated by Comercio after receipt of the purchase price) constitute purchase of future (ungenerated) accounts
receivable which are satisfied only upon the generation of Eligible Receivables of Designated Customers by Comercio, which without further action are transferred to, and become the property of the Company.

Under certain circumstances, upon failure by Comercio to perform under certain of its covenants under the RPA, the Company may choose to require Services, and Services
to require Comercio, to repurchase all or any of the outstanding accounts receivable (whether current or future).

The Company is also exposed to the risk
associated with Comercios ability to generate the appropriate volume of accounts receivable of Designated Customers, which is dependent on numerous factors including production, demand and price levels of Mexican crude oil.

The Company is exposed to interest rate risk on long-term floating rate instruments.At December 2005 and 2004, the proportion of floating rate debt was 8.2% and
5.3%, respectively, to total debt outstanding. This rise is mitigated since the income discount rate is based in the same floating rate.

Under the terms
of the RPA, absent a failure by Comercio to comply with its covenants, the Company has no recourse against Comercio in the event that a current purchased receivable that was properly generated and meets the eligibility criteria set forth in the RPA
becomes uncollectible.

The Company ensures that adequate funds are available to meet its financial commitments by applying an income discount rate based
on: 1) its current debt service costs, 2) other administrative expenses, and 3) a mark-up. In addition, the Company maintains a liquidity account equal to the sum of the next payment of debt service.

At December 31, 2005 and 2004, the carrying amounts of cash and cash equivalents, liquidity account, purchased accounts receivable and accruals and accounts payable
approximate their fair value due to the relative short maturity of such instruments. The estimated fair value of the long-term publicly traded debt is the published price quotation in the market at December 31, 2005 and is shown in Note 6. The
estimated fair value of the subordinated debt to PEMEX is determined by discounting the amounts of future interest and principal payments, at the three-month LIBOR rate at the date of fair value calculation plus 300 basis points.

The ability of the Company to meet its obligations with respect to its indebtedness depends on:

1) the ability of Comercio, operating through PEMEX, to generate sufficient Eligible Receivables of Designated Customers, which is in turn dependent upon
the existence of demand for PEMEXs crude oil, 2) any adverse change in the business or financial condition of a Designated Customer that could affect the customers ability to make timely payments with respect to purchased receivables,
and 3) the continuing ability of the Designated Customers to purchase Mexican crude oil from Comercio.

NOTE
4LIQUIDITY ACCOUNT:

Under the Fiscal and Paying Agency Agreement (Fiscal Agency Agreement) dated as of December 1, 1998 among the Company,
The JP Morgan Chase Bank, as Fiscal Agent, and The Chase Manhattan Bank of Luxembourg, S. A., as Paying Agent, the Company is required to maintain an account with the Fiscal Agent designated as the Liquidity Account. Under the terms of the
Companys long-term notes (excluding subordinated debt to PEMEX), the cash balance and permitted investment standing to credit such account at any date, shall be at least equal to an amount, determined at such date, equal to the sum of the next
payment of debt service. At December 31, 2005 and 2004, the balance in the Liquidity Account represents cash and permitted investment standing to the credit of such account, including interest earned on such amounts, and such balance is not
considered to be cash equivalent.

NOTE 5CURRENT AND FUTURE PURCHASED ACCOUNTS RECEIVABLE:

As mentioned in Notes 1 and 2b, the Company purchases Eligible Receivables of Designated Customers from Services. Other than in limited circumstances, the Company has no
recourse to or claim against Services for funds advanced toward payment of Eligible Receivables (see Note 2b.). Services satisfies all its obligations under the RPA by delivering Eligible Receivables of Designated Customers to the Company in the
order in which they are first generated by Comercio, without regard to any concentration limit by Designated Customers.

maintain a debt service coverage ratio of at least 3 to 1, which is calculated as the sum of: 1) the aggregate amount of quarterly payments made to the Company by obligors on the purchased receivables, 2) capital contributions, including the
proceeds of the subordinated debt, in the form of cash or permitted investments, and 3) quarterly income from permitted investments, divided by the maximum aggregate amount of scheduled debt service. As of December 31, 2005 and 2004, the

thereof, at an aggregate redemption price equal to US$1,098.4 million. The redemption price was equal to 100% of the outstanding principal amount of each series of Notes that were redeemed (an aggregate of US$994 million), plus: i) accrued and
unpaid interest thereon to the redemption date (an aggregate of US$8 million), plus ii) an amount equal to the applicable make-whole premium calculated pursuant to the relevant supplemental indenture (an aggregate of US$96.4 million).

During the year ended December 31, 2005, the Company paid principal amounting to US$1,299 million (US$345 million during 2004).

years ended December 31, 2005 and 2004, the Company purchased from Services accounts receivable and rights to future (ungenerated) accounts receivable totaling US$16,807,310 and US$14,749,776, respectively. Also, at December 31, 2005 and
2004, the Company has subordinated debt outstanding from PEMEX of US$238,446 and US$725,661 (see Notes 6 and 7).

Pursuant to the RPA, the Company pays to
Services a margin for services provided, recorded in general and administrative expenses in the statements of income. Total fees paid during the year ended December 31, 2005 amounted to US$1,146.49 (US$932.9 for the year ended December 31,

NOTE 9INCOME TAXES:

The Company is exempt from taxes under the law of the Cayman Islands. No income tax was paid during the years ended December 31, 2005, 2004 and 2003.

NOTE 10SHAREHOLDERS EQUITY:

The Companys authorized share capital consists of 1,000 ordinary shares, par value per share of one US dollar, all of which are issued and paid. Each share is subject to the provisions of the Cayman Islands Companies Law (1998
Revision) and the Articles of Association. The Company has the power to redeem or purchase any of its shares, to sub-divide or consolidate the shares, to issue all or any part of its capital whether original, redeemed, increased or reduced with or
without any preference, priority or special privilege or subject to any postponements of rights or to any conditions or restrictions whatsoever. Unless the conditions of issue shall otherwise expressly provide, every issue of shares whether
Ordinary, Preferred or otherwise shall be subject to the powers on the part of the Company herein provided.

Pursuant to an agreement dated July 1,
2005, between PEMEX and BNP Paribas Bank, the latter granted PEMEX an option to purchase all the shares owned by BNP Paribas Bank on or after the Company repays all its indebtedness. In the event PEMEX decided to exercise this option, the applicable
purchase price would be US$10 per share.

NOTE 11DIFFERENCES BETWEEN IFRS AND ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED STATES
(U.S. GAAP):

The Companys financial statements are prepared in accordance with IFRS. As of December 31, 2005 and 2004 and for
the years ended December 31, 2005, 2004 and 2003, the application of U.S. GAAP would not have produced differences with respect to the Companys shareholders equity and the net income, however there are two differences related to the
balance sheet presentation.

Under IFRS, borrowings are recognized initially at fair value, net of transactions costs incurred. Borrowings are subsequently
stated at amortized cost using the effective yield method; any redemption difference between proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings. Under U.S. GAAP, debt
issuance cost is capitalized and presented as an asset as a deferred charge, and amortized over the life of the debt. As of December 31, 2005 and 2004, the reclassified debt issuance costs are US$172 and US$363, respectively.

Under IFRS, any unearned discount at the date of the financial statements is presented netting the current purchased account receivable. Under U.S. GAAP unearned
discount is presented as a deferred revenue.
