such change results in a change in the method of calculation of financial covenants, standards or terms in this Agreement, then the Borrower and the Lender agree to enter into negotiations in order to amend such provisions of this Agreement so as to
equitably reflect such change in Mexican FRS with the desired result that the criteria for evaluating the Borrowers financial condition shall be the same after such change as if such change had not been made. Until such time as such an

annum determined in accordance with the table below (the Facility Fee), and shall be applied to the Lenders Average Outstanding Loan for
such Calculation Period and will accrue on, and be calculated based on, the number of days elapsed in such Calculation Period. The Facility Fee for each Calculation Period will be as set forth below determined in accordance with the Consolidated Net
Debt / EBITDA Ratio calculated based on the financial statements delivered, or required to be delivered, on the applicable Calculation Date:



|                                                            |  |              |

|Less than or equal to 3.75 to 1, but greater than 3.50 to 1 |  | 0.5          | %
|                                                            | 
|Less than or equal to 3.50 to 1                             |  | 0            | %

The Facility Fee shall be payable within five Business Days after the Calculation Date applicable
to each relevant Calculation Period (the Facility Fee Payment Date); provided that, in respect of any Calculation Period in which the Loan is repaid or prepaid in full, the Facility Fee Payment Date in respect of
such Calculation Period shall be deemed to occur on the date of such repayment or prepayment. Notwithstanding the above, no Facility Fee shall be payable in respect of any Calculation Period in which an acceleration of any Loan occurs or in respect
of any fiscal quarter thereafter.

For purposes of this Section 4, the following definitions shall apply:

Average Outstanding Loan means, for any fiscal quarter, the aggregate principal amount of the Loan outstanding under the Credit Agreement as of the end
of each day during such fiscal quarter, divided by the number of days in such fiscal quarter.

Calculation Date means with respect to
each Calculation Period, the earlier of the date on which the Borrower delivers, or is required to deliver its financial statements with respect to the fiscal quarter ending on the last day of such Calculation Period in accordance with Sections
7.01(a) and 7.01(b) of the Credit Agreement; provided, however, that the Calculation Date for the final Facility Fee Payment Date shall be the date on which the financial statements for the most recently completed fiscal quarter for which
financial statements are required to have been delivered pursuant Sections 7.01(a) and 7.01(b) of the Credit Agreement have been delivered or were required to be delivered.

Calculation Period means each fiscal quarter; provided, however, the first Calculation Period shall commence on the Amendment No. 1 Effective Date and the last Calculation Period
shall end on the last Facility Fee Payment Date.

Schedule 5.06

Litigation

A description of material actions, suits, investigations, litigations or proceedings,
including Environmental Actions, affecting Borrower or any of its Subsidiaries before any court, Governmental Authority or arbitrator is provided below.

Environmental Matters

United States

As of November 30, 2008, CEMEX, Inc. and its subsidiaries had accrued liabilities specifically relating to environmental matters in the aggregate amount of approximately U.S.$42.6 million. The environmental
matters relate to (i) the disposal of various materials, in accordance with past industry practice, which might be categorized as hazardous substances or wastes, and (ii) the cleanup of sites used or operated by CEMEX, Inc., including
discontinued operations, regarding the disposal of hazardous substances or wastes, either individually or jointly with other parties. Most of the proceedings are in the preliminary stage, and a final resolution might take several years. For purposes
of recording the provision, CEMEX, Inc. considers that it is probable that a liability has been incurred and the amount of the liability is reasonably estimable, whether or not claims have been asserted, and without giving effect to any possible
future recoveries. Based on information available to date, CEMEX, Inc. does not believe it will be required to spend significant sums on these matters, in excess of the amounts previously recorded. The ultimate cost that might be incurred to resolve
these environmental issues cannot be assured until all environmental studies, investigations, remediation work, and negotiations with or litigation against potential sources of recovery have been completed.

CEMEX Construction Materials Florida, LLC f/k/a Rinker Materials of Florida, Inc., a subsidiary of CEMEX, Inc., holds one federal quarry permit and is
the beneficiary of one of 10 other federal quarrying permits granted for the Lake Belt area in South Florida. The permit held by CEMEX Florida covers CEMEX Florida's SCL and FEC quarries. CEMEX Florida's Krome quarry is operated under one of the
other federal quarry permits. The FEC quarry is the largest of CEMEX Floridas' quarries measured by volume of aggregates mined and sold. CEMEX Florida's Miami cement mill is located at the SCL quarry and is supplied by that quarry. A ruling was
issued on March 22, 2006 by a judge of the U.S. District Court for the Southern District of Florida in connection with litigation brought by environmental groups concerning the manner in which the permits were granted. Although not named as a
defendant, CEMEX Florida has intervened in the proceedings to protect its interests. The judge ruled that there were deficiencies in the procedures and analysis undertaken by the relevant governmental agencies in connection with the issuance of the
permits. The judge remanded the permits to the relevant governmental agencies for further review, which review the governmental agencies have indicated in a recent announcement should take until mid February 2009 to conclude. The judge also
conducted further proceedings to determine the activities to be conducted during the remand period. In July 2007, the judge issued a ruling that halted certain quarrying operations at three non-CEMEX Florida quarries. The judge left in place CEMEX
Florida's Lake Belt permits until the relevant government agencies complete their review. In a May 2008 ruling, the federal appellate court determined that the district court judge did not apply the proper standard of review to the permit issuance
decision of the governmental agency, vacated the district court's prior order, and remanded the proceeding to the district court to apply the proper standard of review; this review remains pending before the district court judge. If the Lake Belt
permits are ultimately set aside or quarrying operations under them restricted, CEMEX Florida will need to source aggregates, to the extent available, from other locations in Florida or import aggregates. This would likely



---

affect profits from our Florida operations. Any adverse impacts on the Florida economy arising from the cessation or significant restriction of quarrying
operations in the Lake Belt could also have a material adverse effect on our financial results.

Europe

In Great Britain, future expenditure on closed and current landfill sites has been assessed and quantified over the period in which the sites are
considered to have the potential to cause environmental harm, generally consistent with the regulator view of up to 60 years from the date of closure. The assessed expenditure relates to the costs of monitoring the sites and the installation, repair
and renewal of environmental infrastructure. The costs have been quantified on a net present value basis in the amount of approximately £122 million, and an accounting provision for this sum has been made at December 31, 2007.

In 2003, the European Union adopted a directive implementing the Kyoto Protocol on climate change and establishing a greenhouse gas
emissions allowance trading scheme within the European Union. The directive requires Member States to impose binding caps on carbon dioxide emissions from installations involved in energy activities, the production and processing of ferrous metals,
the mineral industry (including cement production) and the pulp, paper or board production business. Under this scheme, companies with operations in these sectors receive from the relevant Member States allowances that set limitations on the levels
of greenhouse gas emissions from their installations. These allowances are tradable so as to enable companies that manage to reduce their emissions to sell their excess allowances to companies that are not reaching their emissions objectives.
Companies can also use credits issued from the use of the flexibility mechanisms under the Kyoto protocol to fulfill their European obligations. These flexibility mechanisms provide that credits (equivalent to allowances) can be obtained by
companies for projects that reduce greenhouse gas emissions in emerging markets. These projects are referred to as Clean Development Mechanism ("CDM") or joint implementation projects depending on the countries where they take place. Failure to meet
the emissions caps is subject to heavy penalties.

Companies can also use, up to a certain level, credits issued under the flexible
mechanisms of the Kyoto protocol to fulfill their European obligations. Credits for Emission Reduction projects obtained under these mechanisms are recognized, up to a certain level, under the European emission trading scheme as allowances. To
obtain these emission reduction credits, companies must comply with very specific and restrictive requirements from the United Nations Convention on Climate Change (UNFCC).

As required by directive, each of the Member States established a National Allocations Plan, or NAP, setting out the allowance allocations for each
industrial facility for Phase I, from 2005 to 2007. Based on the NAPs established by the Member States of the European Union for the 2005 to 2007 period and our actual production, on a consolidated basis after trading allowances between our
operations in countries with a deficit of allowances and our operations in countries with an excess of allowances, and after some external operations, Borrowers Subsidiaries had a surplus of allowances of approximately 1,050,054 tons of carbon
dioxide in this Phase I.

For Phase II, comprising 2008 through 2012, however, there has been a reduction in the allowances granted by the
Member States that have already approved their NAP, which may result in a consolidated deficit in our carbon dioxide allowances during the period. We believe we may be able to reduce the impact of any deficit by either reducing carbon dioxide
emissions in our facilities or by obtaining additional emission credits through the implementation of CDM projects. If we are not successful in implementing emission reductions in our facilities or obtaining credits from CDM projects, we may have to
purchase a significant amount of emission credits in the market, because CEMEX has already sold a substantial amount of allowances for Phase II, the cost of which may have an impact on our



---

operating results. As of December 1, 2008, the market value of carbon dioxide allowances for Phase II was approximately 15.45  per ton. CEMEX is
taking all the measures to minimize our exposure to this market while assuring the supply of our products to our clients.

The Spanish NAP
has been finally approved by the Spanish Government, reflecting the conditions that were set forth by the European Commission. The allocations made to our installations allow us to foresee certain availability of allowances, nevertheless, there
remains the uncertainty regarding the allocations that, against the reserve for new entrants, shall be requested for the new CEMEX cement plant in Andorra (Teruel), currently under construction, and that it is scheduled to start operating in 2010.

On May 29, 2007, the Polish government filed an appeal before the Court of First Instance in Luxemburg regarding the European
Commission's rejection of the initial version of the Polish NAP. The Court has denied Poland's request for a quick path verdict in the case, keeping the case in the regular proceeding path, therefore, the Polish government has started to prepare
Polish internal rules on division of allowance at the level already accepted by the European Commission. Seven major Polish cement producers, representing 98% of Polish cement production (including CEMEX Polska), have also filed seven separate
appeals before the Court of First Instance regarding the European Commission's rejection. On September 29, 2008 the Court of the First Instance issued an order rejecting CEMEX Polskas appeal without going into the merit of the case. As of
December 4, 2008 the final version of the Polish NAP has not been cleared by the Commission; CEMEXs has not determined the impact this may have on CEMEX ̈s position in the country.

Tax Matters

Pursuant to amendments to the
Mexican income tax law (Ley del Impuesto sobre la Renta), which became effective on January 1, 2005, Mexican companies with direct or indirect investments in entities incorporated in foreign countries whose income tax liability in those
countries is less than 75% of the income tax that would be payable in Mexico will be required to pay taxes in Mexico on passive income such as dividends, royalties, interest, capital gains and rental fees obtained by such foreign entities, provided
that the income is not derived from entrepreneurial activities in such countries (income derived from entrepreneurial activities is not subject to tax under these amendments). We filed two motions in the Mexican federal courts challenging the
constitutionality of the amendments. On June 29, 2006, we obtained a favorable ruling from the Mexican federal court stating that the amendments were unconstitutional. The Mexican tax authority appealed the ruling, and the proceeding was
attracted by the Mexican Supreme Court of Justice. On September 9, 2008, the Mexican Supreme Court ruled against CEMEX's constitutional challenge of the controlled foreign corporation tax rules in effect in Mexico for tax years 2005 to 2007.
Since the Supreme Court's decision does not pertain to an amount of taxes due or other tax obligations, CEMEX will self-assess any taxes due through the submission of amended tax returns. CEMEX has not yet determined the amount of tax or the periods
affected. Based on a preliminary estimate, CEMEX believes this amount will not be material, but no assurance can be given that additional analysis will not lead to a different conclusion. If the tax authorities do not agree with CEMEX's
self-assessment of the taxes due for past periods, they may assess additional amounts of taxes past due, which may be material and may impact CEMEX cash flows.

The Mexican Congress approved several amendments to the Mexican Asset Tax Law (Ley del Impuesto al Activo) that came into effect on January 1, 2007. As a result of such amendments, all Mexican corporations,
including us, are no longer allowed to deduct their liabilities from the calculation of the asset tax. We believe that the Asset Tax Law, as amended, is against the Mexican constitution. We have challenged the Asset Tax Law through appropriate
judicial action (juicio de amparo).



---

The asset tax was imposed at a rate of 1.25% on the value of most of the assets of a Mexican corporation.
The asset tax was "complementary" to the corporate income tax (impuesto sobre la renta) and, therefore, was payable only to the extent it exceeded payable income tax.

Philippines

As of November 30, 2008, the Philippine Bureau of Internal Revenue (BIR), had
assessed APO, Solid, IQAC, ALQC and CSPI, our operating subsidiaries in the Philippines, for deficiency taxes covering taxable years 1998-2005 amounting to a total of approximately 1,994 million Philippine Pesos (approximately U.S.$40.727
million as of November 30, 2008, based on an exchange rate of Philippine Pesos 48.96 to U.S.$1.00, which was the Philippine Peso/Dollar exchange rate on November 30, 2008 as published by the Bangko Sentral ng Pilipinas, the central bank of
the Republic of the Philippines).

The majority of the tax assessments result primarily from the disallowance of APO's income tax holiday
incentives for taxable years 1999 to 2001 (approximately Philippine Pesos 1,078 million or U.S.$22.1 million as of November 30, 2008, based on an exchange rate of Philippine Pesos 48.96 to U.S.$1.00). We have contested the BIR's
assessment, arising from the disallowance of the ITH incentive, with the Court of Tax Appeals (CTA). The initial Division ruling of the CTA was unfavorable, but is subject to further appeal with the CTA as a whole. The assessment is now currently on
appeal with the CTA En Banc. A motion was filed with the CTA, requesting the court to hold APO totally not liable for alleged income tax liabilities for all the years covered and to this end cancel and withdraw APO's deficiency income tax
assessments for taxable years 1999, 2000 and 2001 on the basis of APO's availment of the tax amnesty described below. As of November 30, 2008, resolution on the aforementioned motion is still pending.

CEMEX Venezuelan Nationalization

In
furtherance of Venezuelas announced policy to nationalize certain sectors of the economy, on June 18, 2008, the Nationalization Decree was promulgated, mandating that the cement production industry in Venezuela be reserved for the
Government of Venezuela and ordering the conversion of foreign-owned cement companies, including CEMEX Venezuela, into state-controlled companies with Venezuela holding an equity interest of at least 60%. The Nationalization Decree provided for the
formation of a transition committee to be integrated with the board of directors of the relevant cement company to guaranty the transfer of control over all activities of the relevant cement company to Venezuela by December 31, 2008. The
Nationalization Decree further established a deadline of August 17, 2008 for the shareholders of foreign-owned cement companies, including CEMEX Venezuela, to reach an agreement with the Government of Venezuela on the compensation for the
nationalization of their assets. The Nationalization Decree also provided that this deadline may be extended by mutual agreement of the Government of Venezuela and the relevant shareholder. The transition committee, which was to be coordinated by
the Ministry of Basic Industries (MIBAN), was never formally instituted and MIBAN never acted in the process, but instead Petroleos de Venezuela (PDVSA) conducted all the conversations.

CEMEX Venezuela and the Government did not reach agreement by the August 17 deadline, and on August 18 the Expropriation Decree was issued by
the President of Venezuela, with PDVSA appointed to conduct the expropriation proceedings. Although these proceedings had not yet commenced, PDVSA officials headed a group of PDVSA workers, with the support of the public force, to take over all the
facilities of CEMEX Venezuela on August 17. Since no agreement has been reached with the Venezuelan Government as to the compensation to be paid, the Dutch companies that control CEMEX Venezuela filed an arbitration request before the
International Center for the Settlement of Investment Disputes against the Government of Venezuela, which request has been registered and the tribunal is in the process of being formed.

As of December 31, 2007, CEMEX Venezuela, S.A.C.A. was the holding entity of several of CEMEX's
investments in the region, including CEMEX's operations in the Dominican Republic and Panama, as well as CEMEX's minority investment in Trinidad. In the wake of statements by the Government of Venezuela about the nationalization of assets in
Venezuela, in April 2008, CEMEX concluded the transfer of all material non-Venezuelan investments to CEMEX España for approximately U.S.$355 million plus U.S.$112 million of net debt, having distributed all accrued profits from the
non-Venezuelan investments to the stockholders of CEMEX Venezuela amounting to approximately U.S.$132 million. At this time, the net impact or the outcome of the nationalization on CEMEX's consolidated financial results cannot be reasonably
estimated. As of June 30, 2008 the net assets of CEMEX's Venezuelan operations under Mexican FRS were approximately [U.S.$821.7]. Since August 2008, CEMEX no longer consolidates the financial results of CEMEX Venezuela.

On June 13, 2008, the Venezuelan securities authority initiated an administrative proceeding against CEMEX Venezuela, claiming that the company did
not sufficiently inform its shareholders and the securities authority in connection with the transfer of the non-Venezuelan assets described above. The Venezuelan authority determined that CEMEX Venezuela did not comply with its disclosure
obligations and imposed fines on the company, which we do not consider material, and requested the attorney generals office to review the case to determine if such non-disclosure also constituted criminal infringement.

Other Legal Proceedings

On August 5, 2005, a
lawsuit was filed against a subsidiary of CEMEX Colombia, claiming that it was liable along with the other members of the Asociación Colombiana de Productores de Concreto, or ASOCRETO, a union formed by all the ready-mix concrete
producers in Colombia, for the premature distress of the roads built for the mass public transportation system of Bogotá using ready-mix concrete supplied by CEMEX Colombia and other ASOCRETO members. The plaintiffs allege that the base
material supplied for the road construction failed to meet the quality standards offered by CEMEX Colombia and the other ASOCRETO members and/or that they provided insufficient or inaccurate information in connection with the product. The plaintiffs
seek the repair of the roads in a manner which guarantees their service during the 20-year period for which they were originally designed, and estimate that the cost of such repair will be approximately U.S.$45 million. The lawsuit was filed within
the context of a criminal investigation of two ASOCRETO officers and other individuals, alleging that the ready-mix concrete producers were liable for damages if the ASOCRETO officers were criminally responsible. The court completed the evidentiary
stage, and on August 17, 2006 dismissed the charges against the members of ASOCRETO. The other defendants (one ex-director of the Distrital Institute of Development, the legal representative of the constructor and the legal representative of
the contract auditor) were formally accused. The decision was appealed, and on December 11, 2006, the decision was reversed and the two ASOCRETO officers were formally accused as participants (determiners) in the execution of a state contract
without fulfilling all legal requirements thereof. The first public hearing took place on November 20, 2007. In this hearing the judge dismissed an annulment petition filed by the ASOCRETO officers. The petition was based on the fact that the
officers were formally accused of a different crime than the one they were being investigated for. This decision was appealed, but the decision was confirmed by the Superior Court of Bogota. On January 21, 2008, CEMEX Colombia was subject to a
judicial order, issued by the court, sequestering a quarry called El Tujuelo, as security for a possible future money judgment to be rendered against CEMEX Colombia in these proceedings. The court determined that in order to lift this attachment and
prevent further attachments, CEMEX Colombia was required within a period of 10 days to deposit with the Court in cash CoP$337,800 million (approximately



---

U.S.$195 million as of June 4, 2008, based on an exchange rate of CoP1730 to U.S.$1.00, which was the Colombian Peso/Dollar exchange rate on
June 4, 2008, as published by the Banco de la República de Colombia, the central bank of Colombia), instead of being allowed to post an insurance policy to secure such recovery. CEMEX Colombia asked for reconsideration, and the
court allowed CEMEX to present an insurance policy. Nevertheless, CEMEX appealed this decision, in order to reduce the amount of the insurance policy, and also requested that the guarantee be covered by all defendants in the case. The measure does
not affect the normal activity of the quarry. At this stage, we are not able to assess the likelihood of an adverse result or the potential damages which could be borne by CEMEX Colombia.

On August 5, 2005, Cartel Damages Claims, SA, or CDC, filed a lawsuit in the District Court in Düsseldorf, Germany against CEMEX Deutschland AG
and other German cement companies. CDC is seeking 102 million in respect of damage claims by 28 entities relating to alleged price and quota fixing by German cement companies between 1993 and 2002, which entities had assigned their claims
to CDC. CDC is a Belgian company established by two lawyers in the aftermath of the German cement cartel investigation that took place from July 2002 to April 2003 by Germany's Federal Cartel Office with the express purpose of purchasing potential
damages claims from cement consumers and pursuing those claims against the cartel participants. In January 2006, another entity assigned alleged claims to CDC, and the amount of damages being sought by CDC increased to 113.5 million plus
interest. On February 21, 2007, the District Court of Düsseldorf decided to allow this lawsuit to proceed without going into the merits of this case by issuing an interlocutory judgment. All defendants appealed. The appeal hearing took
place on April 22, 2008, and the appeal was dismissed on May 14, 2008. The lawsuit will proceed at the level of court of first instance. As of September 30, 2008 only one defendant has decided to file a complaint before the Federal
High Court; this will delay the case from proceeding at the level of first instance to an extent we cannot assess today. In the meantime, CDC had acquired new assigners and announced an increase in the claim to 131 million. As of
November 30, 2008, we had accrued liabilities regarding this matter for a total amount of approximately 20 million.

After an
extended consultation period, in April 2006, the cities of Katela and Solin in Croatia published their respective Master (physical) Plans defining the development zones within their respective municipalities, adversely impacting the mining
concession granted to Dalmacijacement, our subsidiary in Croatia, by the Government of Croatia in September 2005. During the consultation period, Dalmacijacement submitted comments and suggestions to the Master Plans, but these were not taken into
account or incorporated into the Master Plan by Katela and Solin. Most of these comments and suggestions were intended to protect and preserve the rights of Dalmacijacement ́s mining concession granted by the Government of Croatia in
September 2005. Immediately after publication of the Master Plans, Dalmacijacement filed a series of lawsuits and legal actions before the local and federal courts to protect its acquired rights under the mining concessions. The legal actions taken
and filed by Dalmacijacement were as follows: (i) on May 17, 2006, a constitutional appeal before the constitutional court in Zagreb, seeking a declaration by the court concerning Dalmacijacement's constitutional claim for decrease and
obstruction of rights earned by investment, and seeking prohibition of implementation of the Master Plans. This cases is currently under review by the court in Croatia, and it is expected that these proceedings will continue for several years before
resolution; (ii) on May 17, 2006, a possessory action against the cities of Katela and Solin seeking the enactment of interim measures prohibiting implementation of the Master Plans and including a request to implead the Republic of
Croatia into the proceeding on our side. The municipal court in Solin issued a first instance judgment dismissing our possessory action. We filed an appeal against that judgment. The appeal has been resolved by the Solin County Court, affirming the
judgment and rendering it final. The Municipal Court in Katela has issued a first instance judgment dismissing our possessory action. We filed an appeal against said judgment, which has since been resolved by the Katela Country Court,
affirming the judgment and rendering it final; (iii) on May 17, 2006, an administrative proceeding before the State Lawyer, seeking a declaration from the Government of Croatia confirming that Dalmacijacement acquired rights under the
mining concessions.



---

Dalmacijacement received State Lawyers opinion which confirms the Dalmacijacement's acquired rights according to the previous decisions ("old
concession"). The Administrative Court in Croatia has ruled in favor of Dalmacijacement, validating the legality of the mining concession granted to Dalmacijacement by the Government of Croatia. This decision is final. Currently it is difficult for
Dalmacijacement to ascertain the approximate economic impact of these measures by Katela and Solin).

Club of Environmental
Protection, a Latvian environmental protection organization (hereinafter the Applicant), has initiated a court administrative proceeding against the decision made by the Environment State Bureau (hereinafter the Defendant) in order
to amend the environmental pollution permit (the Permit) for the Broceni Cement Plant in Latvia, owned by CEMEX SIA (the Disputed Decision). CEMEX SIA was invited to participate in the court proceedings as a third party,
whose rights and legal interest may be infringed by the relevant administrative act. On June 5, 2008 the Court rendered its judgment, where it satisfied the Claimants claim and revoked the Disputed Decision stating that it is illegal
because Defendant failed to perform public inquiry in accordance with legal regulations. The judgment has been appealed by both the Defendant and CEMEX SIA before the Court of Appeal and the court will hear the case in February 24, 2009. The
appellate procedure will not suspend the operation of the Permit which will remain valid throughout the court proceedings, hence CEMEX SIA is allowed to continue to perform its activities. The Permit subject to this proceeding was issued for the
existing cement line, which will be fully substituted in the first half of 2009 by a new cement line currently under construction.
