            INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM'S REPORT
            ------------------------------------------------------


Participants and Administrator of
CEMEX, Inc. Savings Plan:

We have audited the accompanying statements of net assets available for
benefits of the CEMEX, Inc. Savings Plan (the Plan) as of December 30, 2004
and 2003, and the related statement of changes in net assets available for
benefits for the year ended December 30, 2004. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards as established by the Auditing Standards Board (United States) and
in accordance with the standards of the 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. The Plan is not required to have, nor were
we engaged to perform, an audit of its internal control over financial
reporting. Our audit included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in
the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Plan's internal control over financial reporting.
Accordingly, we express no such opinion. 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 as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 30, 2004 and 2003, and the changes in net assets available for
benefits for the year ended December 30, 2004, in conformity with accounting
principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets
(held at end of year) is presented for the purpose of additional analysis and
is not a required part of the basic financial statements but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan's
management. The supplemental schedule has been subjected to the auditing
procedures applied in the audit of the 2004 basic financial statements and, in
our opinion, is fairly stated in all material respects in relation to the 2004
basic financial statements taken as a whole.

                         Notes to Financial Statements
                          December 30, 2004 and 2003

1.   Plan Description

     General
     -------

     The Cemex USA Management, Inc. Savings Plan was adopted effective April
     1, 1991 for the benefit of the employees of Cemex Management, Inc.
     (formerly known as Cemex USA Management, Inc.) and its affiliated
     companies. Effective January 1, 2001, CEMEX, Inc. (Employer) assumed
     sponsorship of the Cemex USA Management, Inc. Savings Plan and changed
     the plan's name to CEMEX, Inc. Savings Plan (the Plan).

     Effective April 1, 2005, the union employees of the Clinchfield, Georgia
     plant ceased participating in the CEMEX, Inc. Savings and Investment Plan
     for Union Employees and became participants in the Plan. In connection
     therewith, assets of $3,579,136 were transferred into the Plan from the
     CEMEX, Inc. Savings and Investment Plan for Union Employees subsequent to
     December 30, 2004.

     In connection with CEMEX, Inc.'s purchase of Neoris USA, Inc., assets of
     $1,647,674 were transferred from the Neoris USA, Inc. 401(k) Profit
     Sharing Plan into the Plan during 2004.

     Effective September 1, 2003, the union employees of CEMEX, Inc.'s
     Charlevoix, Michigan plant became participants in the Plan. Accordingly,
     assets of $3,676,704 were transferred from the CEMEX, Inc. Savings and
     Investment Plan for Union Employees into the Plan during 2003.

     The Plan is intended to qualify under section 401(a) of the Internal
     Revenue Code (IRC) as a profit sharing plan with a 401(k) feature. The
     Plan is subject to the provisions of the Employee Retirement Income
     Security Act of 1974 (ERISA), as amended.

     The Plan Agreement was completely amended and restated effective August
     1, 2004. The following brief description of the Plan is provided for
     general information purposes only and is as of December 30, 2004, unless
     otherwise noted. The capitalized words and phrases used in the following
     subsections of this note, shall have the meanings as set forth in the
     Plan Agreement and are as of December 30, 2004 unless otherwise noted.
     Participants should refer to the amended and restated Plan Agreement for
     a complete description of the Plan's provisions.

     Eligibility
     -----------

     Except as otherwise noted, Employees of CEMEX, Inc. and its affiliated
     companies that have adopted the Plan are eligible to participate in the
     Plan on the first day of the calendar quarter following the Employee's
     date of hire. All Employees who are covered by a collective bargaining
     agreement shall be excluded from participating in the Plan, unless the
     collective bargaining agreement requires that the Employer include such
     Employees in this Plan. Any Employee who is notified that he is eligible
     to participate in a foreign retirement plan maintained by CEMEX, Inc. or
     any company in any country operating under the parent company of CEMEX,
     S.A. de C.V. shall be ineligible to participate in this Plan as of the
     first day of the month following the month he or she is notified of his
     or her eligibility to participate in such foreign retirement plan, and
     shall remain ineligible until the first day of the month following the
     month he or she is notified that he or she is no longer eligible to
     participate in such foreign retirement plan.

                                                                       Continued
                                      4

                   Notes to Financial Statements, Continued


     Contributions
     -------------

     Employees may make voluntary contributions of up to 40% of eligible
     compensation on a before-tax basis and an additional 18% of eligible
     compensation on an after-tax basis. Participants who are or will attain
     age 50 years old or older before the close of the Plan's year, are
     eligible to make a catch-up contribution in accordance with section
     414(v) of the IRC. Participants may also contribute amounts representing
     distributions from other qualified defined benefit or contribution plans.
     Participants direct the investment of their participant contributions in
     the investment options listed in note 3.

     The Employer makes matching contributions equal to 75% of the
     participant's before-tax contributions, including catch-up contributions,
     which do not exceed 6% of his or her eligible compensation. The Employer
     contributions are in the form of American Depository Shares representing
     common stock of CEMEX, S.A. de C.V. (CEMEX stock). A participant may, at
     any time after the CEMEX stock is credited to his or her account, make a
     diversification election and exercise investment discretion with respect
     to the Employer matching contribution. The Employer may make additional
     minimum contributions in accordance with the provisions of the Plan
     Agreement.

     Participant accounts
     --------------------

     Separate accounts are maintained for each participant. Participant
     accounts are credited with the participant's contribution and allocations
     of the Employer's contributions and Plan earnings. Allocations are based
     on each participant's earnings or account balance, as defined in the Plan
     Agreement. Each participant is entitled to the benefit that can be
     provided from the participant's vested account.

     Vesting
     -------

     Participants are immediately vested in their employee and rollover
     contributions plus actual earnings thereon. Vesting in the Employers'
     matching and discretionary minimum contribution portion of their accounts
     plus earnings thereon is based on years of continuous service as follows:

                  Completed Years of Active Service           Vesting %
                  ---------------------------------           ---------

                  Three years but less than four years            60%
                  Four years but less than five years             80%
                  Five years or more                             100%

     Each participant who was first employed by Southdown, Inc. prior to
     January 1, 2000, all Louisville Employees and Charlevoix Employees who
     were participants in the CEMEX, Inc. Savings and Investment Plan for
     Union Employees as of September 1, 2003 are fully vested in their entire
     account balance. Louisville Employees hired before July 1, 2004 are 100%
     vested in all Employer matching contributions. Louisville Employees hired
     after July 1, 2004 are vested according to the table shown above.

                                                                     Continued

                  Five years or more                              100%

     Forfeitures
     -----------

     Forfeited amounts are first used to restore forfeited amounts for
     participants who have previously terminated but qualify for restoration
     under the terms of the Plan Agreement. If any amount remains after that
     allocation, it may be used to reduce the Employer matching contribution
     for that year. At December 30, 2004 and 2003, forfeited non-vested
     accounts totaled $50,998 and $363,364, respectively. During fiscal year
     2004, Employer contributions were reduced by $633,288 from forfeited
     non-vested accounts.

     Benefit payments
     ----------------

     Benefits are payable from participant account balances, subject to
     certain restrictions, upon termination of employment, retirement,
     reaching the age of 59 1/2, or by incurring a disability or financial
     hardship, as defined in the Plan Agreement. Participants elect the method
     of distribution which may be either in the form of a direct rollover to
     an eligible retirement plan, lump sum payment or, if in excess of $5,000,
     payment over a period of time not to exceed the shorter of 10 years or
     certain life expectancies as defined in the Plan Agreement. Participants
     may elect that their portion of account balances invested in full shares
     of CEMEX stock or Crane Company common stock be distributed in-kind.

     Participant loans
     -----------------

     A participant may obtain a loan from his or her separate account balance.
     Each loan is evidenced by a promissory note and may not be less than
     $1,000. The loans are secured by the balance in the participant's account
     and bear interest at a rate commensurate with commercial prevailing rates
     as determined by the Administrator. Provisions of the Plan require the
     aggregate of each loan outstanding not to exceed the lesser of $50,000 or
     50% of the participant's vested account balance. Repayment terms for
     loans are not to exceed five years and principal and interest is paid
     ratably through monthly payroll deductions.

     Plan termination
     ----------------

     Although no interest has been expressed, CEMEX, Inc. has the right under
     the Plan to terminate the Plan subject to the provisions of ERISA. In the
     event of Plan termination, participants become 100% vested in their
     Employer contributions account. Participant contributions are always 100%
     vested.

                                                                       Continued

2.   Significant Accounting Policies

     Basis of presentation
     ---------------------

     The financial statements have been prepared on an accrual basis and
     present the net assets available for plan benefits and changes in those
     net assets in accordance with accounting principles generally accepted in
     the United States of America.

     Investment valuation and income recognition
     -------------------------------------------

     The mutual funds, common collective trust fund and common stock are
     stated at fair value based on quoted market prices as of the date of the
     financial statements. Participant loans are valued at their outstanding
     balances, which approximate fair value. Purchases and sales of securities
     are recorded on a trade-date basis. Interest income is recorded on the
     accrual basis. Dividends are recorded on the ex-dividend date.

     Benefit payments
     ----------------

     Benefits are recorded when paid.

     Administrative expenses
     -----------------------

     Loan fees are paid by the borrowing participant and all other
     administrative costs are paid by the Employer.

     Use of estimates
     ----------------

     The preparation of financial statements in conformity with accounting
     principles generally accepted in the United States of America requires
     management to make estimates and assumptions that affect the reported
     amounts of assets, liabilities, and changes therein, and disclosure of
     contingent assets and liabilities. Actual results could differ from those
     estimates.

                                                                       Continued

     Investments with a fair value that exceeds $12,854,438 at December 30,
     2004 and $11,226,830 at December 30, 2003 represent 5 percent or more of
     Plan net assets.

4.   Federal Income Tax Status

     The Plan obtained its latest determination letter on November 20, 2002 in
     which the Internal Revenue Service stated that the Plan, as then
     designed, was in compliance with the applicable requirements of the IRC.
     The Plan has been amended since receiving the determination letter.
     However, the Plan's management believes that the Plan is designed and is
     currently being operated in compliance with the applicable requirements
     of the IRC. Therefore, the Plan's management believes that the related
     trust is tax-exempt and accordingly, no provision for Federal income
     taxes has been included in the Plan's financial statements.

5.   Risks and Uncertainties

     The Plan provides for investment in a common collective trust fund,
     various mutual funds, and common stock. Investment securities, in
     general, are exposed to various risks, such as interest rate, credit and
     overall market volatility risks. Due to the level of risk associated with
     certain investment securities, it is at least reasonably possible that
     changes in the values of investment securities will occur in the near
     term and that such changes could materially affect participants' account
     balances and the amounts reported in the statements of net assets
     available for benefits.

                                                                       Continued
