This Amendment No. 1 to the Tender Offer Statement on Schedule TO relates to the offer by CEMEX, S.A. de C.V. (“CEMEX”), a corporation organized under the laws of the United Mexican States (“Mexico”), to purchase (the “Offer”) at the Selected Purchase Price (as defined in the Offer to Purchase referenced below) all of its issued and outstanding Appreciation Warrants (including Appreciation Warrants represented by ADWs, each ADW representing five Appreciation Warrants), that are tendered in the Offer at or below the Selected Purchase Price, which will be a single price in Mexican Pesos not greater than Ps8.10 per Appreciation Warrant (U.S.$ equivalent of Ps40.50 per ADW) nor less than Ps5.10 per Appreciation Warrant (U.S.$ equivalent of Ps25.50 per ADW) in cash. CEMEX reserves the right to extend the Offer for up to three months or terminate the Offer, in its sole and absolute discretion, which may be for any or no reason, and to otherwise amend the Offer in any respect. The Offer is subject to the terms and conditions set forth in the Offer to Purchase dated November 17, 2003 (the “Offer to Purchase”) and in the related letter of transmittal (which, as either may be amended or supplemented from time to time, together constitute the “Disclosure Documents”). The Offer to Purchase and the letter of transmittal are attached to the Schedule TO filed by CEMEX on November 17, 2003, as Exhibits (a)(1)(A) and (a)(1)(B), respectively. This Amendment No. 1 amends and supplements the Tender Offer Statement on Schedule TO filed on November 17, 2003 by supplementing the disclosure previously provided in response to Item 5(e) and by filing additional exhibits.
 
The responses to the items of the Schedule TO filed on November 17, 2003 are hereby amended and supplemented as follows:

WITNESSETH:

WHEREAS, the Seller beneficially owns 847,638 shares (the "Seller's

NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties and covenants herein contained, intending to be
legally bound hereby, the Parties agree as follows:

ARTICLE I

PURCHASE AND SALE OF SELLER'S SHARES
------------------------------------

1.   Basic Transaction. (a) On and subject to the terms and conditions
of this Agreement and the Escrow Agreement, on March 31, 2003, June 30, 2003,
September 30, 2003 and December 31, 2003 (or if any such day is not a business
day in each of New York, Mexico and Singapore (a "Business Day"), then the first
day thereafter that is a Business Day)(each a "Subsequent Closing Date"), CEMEX
agrees to purchase from the Seller, and the Seller agrees to sell to CEMEX, the
number of Seller's Shares set forth in the column corresponding to such
Subsequent Closing Date opposite the Seller's name on Schedule A to the Escrow
Agreement (such number of Seller's Shares to be sold on a Subsequent Closing
Date being referred to herein as the "Number of Shares").

(b)  Notwithstanding anything to the contrary contained in the
foregoing Article I(1)(a), at any time from and after Closing, upon prior
written notice to the Seller and all other parties to the Escrow Agreement,
CEMEX may designate any Business Day after the thirtieth day following such
notice and prior to a Subsequent Closing Date as the "Early Subsequent Closing
Date" for such Subsequent Closing Date. Following any such designation, such
Early Subsequent Closing Date shall be deemed to be the Subsequent Closing Date
for all purposes under the Transaction Documents, and references to such
Subsequent Closing Date shall be deemed to be references to such Early
Subsequent Closing Date.

(c)  If at any time or from time to time after the date hereof
and prior to the final Subsequent Closing Date, CEMEX designates an Early
Subsequent Closing Date in respect to the Seller's Shares, or in respect to the

shall, in accordance with Section 5(b)(iv) of the Escrow Agreement, (x) deliver
such cash to the Escrow Agent sufficiently in advance of the relevant Subsequent
Closing Date to permit the Escrow Agent to arrange for the purchase of the
Number of CPOs with such funds, and to have such CPOs available for delivery to
the Seller (or its nominee) on such Subsequent Closing Date, and (y) give
written instructions to the Escrow Agent regarding the procedures for such
purchase; and further provided, however, that CEMEX's obligation to deposit the
Number of CPOs on any Subsequent Closing Date to the Seller's Depositary Account
(as defined in the Escrow Agreement) shall not be satisfied until such Number of
CPOs is so deposited. The Number of CPOs to be delivered on a Subsequent Closing
Date pursuant to the preceding sentence shall be adjusted from time to time as
set forth in Article I(5) below.

(b)  At the Closing, subject to the terms and conditions set
forth herein, CEMEX will deliver to the Seller:

(i)   counterparts to the Escrow Agreement and the Amended
Shareholders Agreement, each duly executed by all of the parties thereto on
their own behalf;

(ii)  the officer's certificate contemplated by Article
V(2)(g);

(iii) a counterpart to the Release delivered by the Seller
pursuant to Section 4(a)(iii), duly executed by CAH;

(iv)  a true and complete copy of the Amended and Restated
Charter of CAH (substantially in the form of Exhibit D attached hereto)
(the "Amended and Restated Charter"), as will be lodged by CAH within 14
days from the Closing Date in the Office of the Registrar of Companies and
Business, Singapore (the "Registrar"), conforming CAH's Charter to the
Amended Shareholders Agreement; and

483742.01-New York S4A                 4

(v)   all other previously undelivered documents required by
the Transaction Documents to be delivered by CEMEX at or prior to the
Closing Date.

5.   Adjustments to the Number of CPOs. The Number of CPOs to be
delivered on any Subsequent Closing Date shall be adjusted from time to time as
set forth in this Article I(5); provided, however, that no adjustment shall be
made for any dividend or other distribution paid to or for the benefit of the
Seller pursuant to Article IV(5) below.

(a)  In case CEMEX shall pay or make a dividend or other
distribution on all or any portion of the CEMEX Common Stock exclusively in
CEMEX Common Stock or shall pay or make a dividend or other distribution on any
other class of capital stock of CEMEX which dividend or distribution includes
CEMEX Common Stock, the Number of CPOs as of the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be increased by multiplying
such Number of CPOs by a fraction of which the denominator shall be the number
of shares of all CEMEX Common Stock outstanding at the close of business on the
date fixed for such determination and the numerator shall be the sum of such
number of shares and the total number of shares of CEMEX Common Stock
constituting such dividend or other distribution, such increase to become
effective immediately after the opening of business on the day following the
date fixed for such determination.

(b)  In case CEMEX shall pay or make a dividend or other
distribution on all or any portion of the CEMEX Common Stock consisting of, or
shall otherwise issue to holders of all or any portion of the CEMEX Common
Stock, rights, warrants or options entitling the holders thereof to subscribe
for or purchase shares of any class of CEMEX Common Stock at a price per share
less than the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date fixed for the
determination of stockholders entitled to receive such rights, warrants or
options (each such class, an "affected class"), the Number of CPOs in effect at
the opening of business on the day following the date fixed for such
determination shall be increased by multiplying such number by a fraction of
which the denominator shall be the number of shares of all CEMEX Common Stock
outstanding at the close of business on the date fixed for such determination
plus, for each affected class, the number of shares of such class which the
aggregate of the offering price of the total number of shares of such class so
offered for subscription or purchase would purchase at such current market price
and the numerator shall be the number of shares of all CEMEX Common Stock
outstand-

483742.01-New York S4A                 5

ing at the close of business on the date fixed for such determination plus, for
each affected class, the number of shares of such class so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination.

(c)  In case all or any portion of the outstanding CEMEX Common
Stock shall be subdivided into a greater number of shares of CEMEX Common Stock,
the Number of CPOs in effect at the opening of business on the day following the
day upon which such subdivision becomes effective shall be proportionately
increased (based on the change in the total number of shares of all CEMEX Common
Stock, without regard to classes), and, conversely, in case all or any portion
of the outstanding CEMEX Common Stock shall be combined into a smaller number of
shares of CEMEX Common Stock, the Number of CPOs in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be proportionately reduced (based on the change in the total
number of shares of all CEMEX Common Stock, without regard to classes), such
increase or reduction, as the case may be, to become effective immediately after
the opening of business on the day following the day upon which such subdivision
or combination becomes effective.

(d)  Subject to the last sentence of this paragraph (d), in case
CEMEX shall, by dividend or otherwise, distribute to holders of all or any
portion of the CEMEX Common Stock evidences of CEMEX's indebtedness, shares of
any class of capital stock, securities, cash or property (excluding any rights,
warrants or options referred to in paragraph (b) of this Article I(5), any
dividend or distribution paid exclusively in cash and any dividend or
distribution referred to in paragraph (a) of this Article I(5)), the Number of
CPOs shall be increased so that the same shall equal the number determined by
multiplying the Number of CPOs in effect immediately prior to the effectiveness
of the increase in the Number of CPOs contemplated by this paragraph (d) by a
fraction of which the denominator shall be the current market capitalization
(determined as provided in paragraph (g) of this Article I(5)) of the CEMEX
Common Stock on the date fixed for such distribution less the fair market value
(as determined in good faith by the board of directors of CEMEX, whose
determination shall be conclusive and shall, in the case of securities being
distributed for which prior thereto there is an actual or when issued trading
market, be no less than the value determined by reference to the average of the
closing prices in such market over the period specified in the succeeding
sentence), on the date of such effectiveness, of the evidences of indebtedness,
shares of capital stock, securities, cash and other property so distributed and
the numerator shall be such current market capitalization, such increase to
become effective immediately prior to the opening of

483742.01-New York S4A                 6

business on the day following the date fixed for the payment of such
distribution (such date being referred to as the "Reference Date"). If the board
of directors of CEMEX determines the fair market value of any distribution for
purposes of this paragraph (d) by reference to the actual or when issued trading
market for any securities comprising such distribution, it must in doing so
consider the prices in such market over the same period used in computing the
current market capitalization pursuant to paragraph (g) of this Article I(5).
For purposes of this paragraph (d), any dividend or distribution that includes
shares of CEMEX Common Stock or rights, warrants or options to subscribe for or
purchase shares of CEMEX Common Stock shall be deemed instead to be (A) a
dividend or distribution of the evidences of indebtedness, cash, shares of
capital stock, other securities or other property other than such shares of
CEMEX Common Stock or such rights, warrants or options (making any increase in
the Number of CPOs required by this paragraph (d)) immediately followed by (B) a
dividend or distribution of such shares of CEMEX Common Stock or such rights,
warrants or options (making any further increase in the Number of CPOs required
by paragraph (a) or (b) of this Article I(5), except (A) the Reference Date of
such dividend or distribution as defined in this paragraph (d) shall be
substituted as "the date fixed for the determination of stockholders entitled to
receive such rights, warrants or options" and "the date fixed for such
determination" within the meaning of paragraphs (a) and (b) of this Article I(5)
and (B) any shares of CEMEX Common Stock included in such dividend or
distribution shall not be deemed "outstanding at the close of business on the
date fixed for such determination" within the meaning of paragraph (a) of this
Article I(5)).

(e)  In case CEMEX shall, by dividend or otherwise, make a
distribution to holders of all or any portion of the CEMEX Common Stock
exclusively in cash in an aggregate amount that, together with (A) the aggregate
amount of any other distributions to holders of all or any portion of the CEMEX
Common Stock made exclusively in cash within the 12 months preceding the date of
payment of such distribution and in respect of which no adjustment in the Number
of CPOs pursuant to this paragraph (e) has been made and (B) the aggregate of
any cash plus the fair market value (as determined in good faith by the board of
directors of CEMEX, whose determination shall be conclusive), as of the
expiration of the tender or exchange offer referred to below, of consideration
payable in respect of any tender or exchange offer by CEMEX or a subsidiary of
CEMEX for all or any portion of the CEMEX Common Stock concluded within the 12
months preceding the date of payment of such distribution and in respect of
which no adjustment in the Number of CPOs pursuant to paragraph (f) of this
Article I(5) has been made, exceeds 12.5% of the current market capitalization
of the CEMEX Common Stock (determined as provided in paragraph (g) of this
Article I(5)) on the date fixed for the determination

483742.01-New York S4A                 7

of stockholders entitled to receive such distribution, the Number of CPOs shall
be increased so that the same shall equal the number determined by multiplying
the Number of CPOs in effect immediately prior to the effectiveness of the
number increase contemplated by this paragraph (e) by a fraction of which the
denominator shall be the current market capitalization of the CEMEX Common Stock
(determined as provided in paragraph (g) of this Article I(5)) on the date fixed
for such distribution less the amount of cash distributed in such distribution
and the numerator shall be such current market capitalization, such increase to
become effective immediately prior to the opening of business on the day
following the date fixed for the payment of such distribution.

(f)  In case a tender or exchange offer made by CEMEX or any
subsidiary of CEMEX for all or any portion of the CEMEX Common Stock shall
expire and such tender or exchange offer shall involve an aggregate
consideration having a fair market value (as determined in good faith by the
board of directors of CEMEX, whose determination shall be conclusive) at the
last time (the "Expiration Time") tenders or exchanges may be made pursuant to
such tender or exchange offer (as it may be amended) that, together with (A) the
aggregate of the cash plus the fair market value (as determined in good faith by
the board of directors of CEMEX, whose determination shall be conclusive), as of
the expiration of the other tender or exchange offer referred to below, of
consideration payable in respect of any other tender or exchange offer by CEMEX
or a subsidiary of CEMEX for all or any portion of the CEMEX Common Stock
concluded within the 12 months preceding the Expiration Time and in respect of
which no adjustment to the Number of CPOs pursuant to this paragraph (f) has
been made and (B) the aggregate amount of any distributions to all holders of
the CEMEX Common Stock made exclusively in cash within the 12 months preceding
the Expiration Time and in respect of which no adjustment to the Number of CPOs
pursuant to paragraph (e) of this Article I(5) has been made, exceeds 12.5% of
the current market capitalization of the CEMEX Common Stock (determined as
provided in paragraph (g) of this Article I(5)) at the Expiration Time
(calculated by treating as outstanding any shares tendered for sale or
exchange), the Number of CPOs shall be increased so that the same shall equal
the number determined by multiplying the Number of CPOs in effect immediately
prior to the Expiration Time by a fraction of which the denominator shall be (i)
the current market capitalization of the CEMEX Common Stock (determined as
provided in paragraph (g) of this Article I(5)) at the Expiration Time
(calculated by treating as outstanding any shares tendered for sale or exchange)
minus (ii) the fair market value (determined as aforesaid) of the aggregate
consideration payable to stockholders pursuant to such tender or exchange offer
based on the acceptance (up to any maximum specified in the terms of the tender
or exchange offer) of all shares validly

483742.01-New York S4A                 8

tendered for sale or exchange and not withdrawn as of the Expiration Time (the
shares deemed so accepted, up to any such maximum, being referred to as the
"Purchased Shares") and the numerator shall be such current market
capitalization at the Expiration Time (calculated by reducing the relevant
number of outstanding shares by the number of Purchased Shares), such increase
to become effective immediately prior to the opening of business on the day
following the Expiration Time.

(g)  For the purpose of any computation under this paragraph and
paragraphs (b), (d) and (e) of this Article I(5), the current market price per
share of any class of CEMEX Common Stock on any date in question shall be deemed
to be the average of the daily Closing Prices (as defined herein) for such class
for the five consecutive Trading Days (as defined herein) selected by CEMEX
commencing not more than 20 Trading Days before, and ending not later than, the
date in question; provided, however, that (A) if the "ex" date (as hereinafter
defined) for any event (other than the issuance or distribution requiring such
computation) that requires an adjustment to the Number of CPOs pursuant to
paragraph (a), (b), (c), (d), (e) or (f) above ("Other Event") occurs on or
after the 20th Trading Day prior to the date in question and prior to the "ex"
date for the issuance or distribution requiring such computation (the "Current
Event"), the Closing Price for such class for each Trading Day prior to the "ex"
date for such Other Event shall be adjusted by multiplying such Closing Price by
the reciprocal fraction by which the Number of CPOs is so required to be
adjusted as a result of such Other Event, (B) if the "ex" date for any Other
Event occurs after the "ex" date for the Current Event and on or prior to the
date in question, the Closing Price for such class for each Trading Day on and
after the "ex" date for such Other Event shall be adjusted by multiplying such
Closing Price by the same fraction by which the Number of CPOs is so required to
be adjusted as a result of such Other Event, (C) if the "ex" date for any Other
Event occurs on the "ex" date for the Current Event, one of those events shall
be deemed for purposes of clauses (A) and (B) of this proviso to have an "ex"
date occurring prior to the "ex" date for the other event, and (D) if the "ex"
date for the Current Event is on or prior to the date in question, after taking
into account any adjustment required pursuant to clause (B) of this proviso, the
Closing Price for such class for each Trading Day on or after such "ex" date
shall be adjusted by adding thereto an amount calculated by dividing (1) the
amount of any cash plus the fair market value on the date in question (as
determined in good faith by the board of directors of CEMEX (in a manner
consistent with any determination of such value for purposes of paragraph (d) or
(e) of this Article I(5)), whose determination shall be conclusive) of the
rights, warrants, options, evidences of indebtedness, shares of capital stock,
securities or other property being distributed by (2) the number of all shares
of CEMEX Common Stock

483742.01-New York S4A                 9

outstanding as of the close of business on the day before such "ex" date. For
the purpose of any computation under paragraph (f) of this Article I(5), the
current market price per share of any class of CEMEX Common Stock on any date in
question shall be deemed to be the average of the daily Closing Prices for the 5
consecutive Trading Days selected by CEMEX commencing on or after the latest
(the "Commencement Date") of (A) the date 20 Trading Days before the date in
question, (B) the date of commencement of the tender or exchange offer requiring
such computation and (C) the date of the last amendment, if any, of such tender
or exchange offer involving a change in the maximum number of shares for which
tenders are sought or a change in the consideration offered, and ending not
later than the date of the Expiration Time of such tender or exchange offer
(which shall occur on a day no earlier than the last of the 5 consecutive
trading days beginning on the Commencement Date); provided, however, that if the
"ex" date for any Other Event (other than the tender or exchange offer requiring
such computation) occurs on or after the Commencement Date and on or prior to
the date of the Expiration Time for the tender or exchange offer requiring such
computation, the Closing Price for such class for each Trading Day prior to the
"ex" date for such Other Event shall be adjusted by multiplying such Closing
Price by the reciprocal fraction by which the Number of CPOs is so required to
be adjusted as a result of such other event. For the purpose of any computation
under paragraph (d), (e) or (f) of this Article I(5), the current market
capitalization of the CEMEX Common Stock on any day shall be deemed to be the
sum of the market values for each class of CEMEX Common Stock on such day. For
each such class, the market value on any day shall be deemed to equal the
current market price per share for such class on such day, multiplied by the
number of shares of such class outstanding on such day; provided that, in
determining such number of outstanding shares on such day, no effect shall be
given to any change in the number of such shares outstanding attributable to any
event for which an adjustment was made to any Closing Price used to determine
such current market price pursuant to clause (B) or (D) of the proviso to the
second preceding sentence and provided, further, that the same 5 Trading Days
shall be used to calculate the current market price for each class of CEMEX
Common Stock. Similarly, in determining the number of shares of all CEMEX Common
Stock outstanding on the relevant date for the purpose of calculating any
adjustment in the Number of CPOs pursuant to paragraph (b) of this Article I(5),
no effect shall be given to any change in the number of such shares outstanding
attributable to any event for which adjustment was made pursuant to such clause
(B) or (D) to any Closing Price used to determine the current market price of an
affected class for the purpose of calculating such adjustment. For purposes of
this paragraph, the term "ex" date, (A) when used with respect to any issuance
or distribution, means, with respect to any class of CEMEX Common Stock, the
first date on which such class trades regular way on the relevant

483742.01-New York S4A                 10

exchange or in the relevant market from which the Closing Price was obtained
without the right to receive such issuance or distribution, (B) when used with
respect to any subdivision or combination of shares of CEMEX Common Stock, means
the first date on which such class trades regular way on such exchange or in
such market after the time at which such subdivision or combination becomes
effective, and (C) when used with respect to any tender or exchange offer means
the first date on which such class trades regular way on such exchange or in
such market after the Expiration Time of such tender or exchange offer.

"Closing Price" means (i) in respect of any class of Common Stock, for
any Trading Day, the last reported sale price, regular way, of such Common Stock
or, in case no such reported sale takes place on such Trading Day, the average
of the reported closing bid and asked prices, regular way, of such Common Stock
on the Mexican Stock Exchange (the Bolsa Mexicana de Valores, S.A. de C.V.) or,
if such Common Stock is not listed or admitted for trading on such exchange, the
average of the reported closing bid and asked prices of such Common Stock as
furnished by any three leading Mexican Stock Exchange member firms selected from
time to time by CEMEX for that purpose and (ii) in respect of any class of CPOs
representing Common Stock for any Trading Day, the last reported sale price,
regular way, of or, in case no such reported sale takes place on such Trading
Day, the average of the reported closing bid and asked prices, regular way, for
such CPOs, on the Mexican Stock Exchange or, if such CPOs are not listed or
admitted for trading on such exchange, the average of the reported closing bid
and asked prices of such CPOs as furnished by any three leading Mexican Stock
Exchange member firms selected from time to time by CEMEX for that purpose.

"Trading Day" means each Monday, Tuesday, Wednesday, Thursday and
Friday, other than any day on which the Mexican Stock Exchange is not open for
trading.

(h)  (i)   In case CEMEX shall issue or sell any shares of any
class of CEMEX Common Stock without consideration or at a price per share less
than 90% of the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date of such issuance
or sale, the Number of CPOs in effect at the opening of business on the day
following the date of such issuance or sale shall be increased by:

(A)  multiplying the Number of CPOs in effect at the close
of business on the day immediately preceding the date of
such issuance or sale by

483742.01-New York S4A                 11

(B)  a fraction, of which

(1)  the numerator shall be the number of shares of
CEMEX Common Stock outstanding at the close of
business on the date immediately preceding such
issuance or sale, plus the number of shares of
CEMEX Common Stock so issued or sold, and

(2)  the denominator shall be the number of shares of
CEMEX Common Stock outstanding at the close of
business on the date immediately preceding such
issuance or sale, plus the number of shares of
CEMEX Common Stock which the aggregate
consideration, if any, received (or to be
received) by CEMEX for the total number of such
additional shares of CEMEX Common Stock so issued
or sold would purchase at such current market
price per share.

(ii)  For the purposes of this Article I(5)(h), the issuance
of any warrants, options, subscriptions, or purchase rights with respect to
shares of any class of CEMEX Common Stock and the issuance of any
securities convertible into or exchangeable for shares of any class of
CEMEX Common Stock (or the issuance of any warrants, options or any rights
with respect to such convertible or exchangeable securities) shall be
deemed an issuance of such shares of such class of CEMEX Common Stock at
such time if the Net Consideration Per Share (as hereinafter determined)
which may be received by CEMEX for such CEMEX Common Stock shall be less
than 90% of the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date of such
issuance. Any obligation, agreement, or undertaking to issue warrants,
options, subscriptions, or purchase rights at any time in the future shall
be deemed to be an issuance at the time such obligation, agreement or
undertaking is made or arises.

483742.01-New York S4A                 12

(iii) No adjustment to the Number of CPOs shall be made
under this Article I(5)(h) upon the sale or issuance (or deemed issuance)
of any shares of CEMEX Common Stock pursuant to:

(A)  the exercise of any warrants, options, subscriptions,
or purchase rights or the exercise of any conversion or
exchange rights in any convertible securities, in each case,
outstanding as of the close of business on the date hereof;

(B)  any employee stock option, purchase or incentive plan,
whether or not existing on the date hereof;

(C)  any of the events referred to in paragraphs (a), (b),
(c), (d), (e) and (f) of this Article I(5);

(D)  anti-dilution provisions contained in any of the
securities referred to in the preceding clauses (A), (B) and
(C) hereof; or

(E)  if any adjustment shall previously have been made, or
deemed not required hereunder, upon the issuance of any such
warrants, options, or subscription or purchase rights or
upon the issuance of any convertible securities (or upon the
issuance of any warrants, options or any rights therefor) as
above provided.

(iv)  If the Net Consideration Per Share of any such
warrants, options, subscriptions, or purchase rights or convertible
securities is decreased from time to time, then, upon the effectiveness of
each such decrease, the Number of CPOs shall be adjusted to such Number of
CPOs as would have obtained (A) had the adjustments made upon the issuance
of such warrants, options, rights, or convertible securities been made upon
the basis of the decreased Net Consideration Per Share of such securities,
and (B) had adjustments made to the Number of CPOs since the date of
issuance of such securities been made to the Number of CPOs as adjusted
pursuant to clause (A) above. Any adjustment of the Number of CPOs with
respect to this paragraph which relates to warrants, options,
subscriptions, purchase rights or

483742.01-New York S4A                 13

convertible securities with respect to shares of CEMEX Common Stock shall
be disregarded if, as, when and to the extent such warrants, options,
subscriptions, purchase rights or convertible securities expire or are
canceled without being exercised or converted, so that the Number of CPOs
effective immediately upon such cancellation or expiration shall be the
same as the Number of CPOs in effect at the time of the issuance of the
expired or canceled warrants, options, subscriptions, purchase rights, or
convertible securities with such additional adjustments as would have been
made to that Number of CPOs had the expired or canceled warrants, options,
subscriptions, purchase rights or convertible securities not been issued.

(v)   "Net Consideration Per Share" shall mean the total
amount of consideration, if any, received by CEMEX as of the date of
issuance in respect to the issuance of such warrants, options,
subscriptions, or other purchase rights or convertible or exchangeable
securities, plus the minimum amount of consideration, if any, payable to
CEMEX upon exercise or conversion thereof, divided by the aggregate number
of shares of CEMEX Common Stock that would be issued if all such warrants,
options, subscriptions, or other purchase rights or convertible or
exchangeable securities were exercised, exchanged, or converted, without
giving effect to any possible future upward price adjustments or rate
adjustments.

(vi)  If part or all of the consideration received by CEMEX
in respect to the issuance of CEMEX Common Stock or of any of the
securities described in this Article I(5)(h) consists of property other
than cash, such consideration shall be deemed to have a fair market value
reasonably determined in good faith by the board of directors of CEMEX.

(i)  No adjustment in the Number of CPOs shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Number of CPOs; provided, however, that any adjustments which by reason of this
paragraph (i) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment.

(j)  In addition to the adjustments in the Number of CPOs
required by paragraphs (a), (b), (c), (d), (e), (f) and (h) of this Article
I(5), CEMEX may from time to time in its discretion make such increases in the
Number of CPOs as it considers to be advisable in order to avoid or diminish any
Mexican income tax to any holders of shares of CEMEX Common Stock resulting from
any dividend or distribution of stock or issuance of rights or warrants to
purchase or subscribe for

483742.01-New York S4A                 14

stock or from any event treated as such for income tax purposes or for any other
reasons. (1)

(k)  For purposes of calculating the number of shares of CEMEX
Common Stock at any time outstanding or the number of shares of CEMEX Common
Stock acquired in any tender or exchange offer, the number of shares of CEMEX
held in its treasury shall not be included.

(l)  CEMEX shall ensure that the time for determining the
stockholders entitled to receive any dividend, issuance or other distribution in
respect of any CEMEX Common Stock, the time of effectiveness of any subdivision
or combination of any CEMEX Common Stock and the expiration time of any tender
or exchange offer made by CEMEX or any subsidiary of CEMEX for any CEMEX Common
Stock shall be at or after the close of business on the date fixed for
determining such stockholders, or on the date of such effectiveness or
expiration, as the case may be, so that (whether or not any adjustment to the
Number of CPOs is required pursuant to this Article I(5)) any Subsequent Closing
Date occurring on such date shall be deemed to have occurred prior to such
relevant time on such date.

(m)  Whenever the Number of CPOs is adjusted as herein provided,
CEMEX shall promptly deliver to the Seller a notice setting forth the adjusted
Number of CPOs and showing in reasonable detail the facts upon which such
adjustment is based.

(n)  In the event that CEMEX shall be a party to any transaction
(including any (i) recapitalization or reclassification of all or any portion of
the CEMEX Common Stock (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination of all or any portion of the CEMEX Common Stock), (ii)
consolidation of CEMEX with, or merger of CEMEX into, any other person, or any
merger of another person into CEMEX (other than a merger which does not result
in a reclassification, conversion, exchange or cancellation of any outstanding
CEMEX Common Stock), (iii) conveyance, transfer, sale or lease of all or
substantially all of the assets of CEMEX, or (iv) compulsory share exchange)
pursuant to which the CPOs are converted into the right to receive other
securities, cash or other property, then lawful provision shall be made as part
of the terms of such transaction providing that the Seller shall have the right
thereafter, to purchase the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, reclassification,
conveyance, transfer or sale by a holder of the Number of CPOs which the Seller
was entitled to purchase immediately prior to such consolidation,

483742.01-New York S4A                 15

merger, reclassification, conveyance, transfer or sale (the "Transaction
Consideration"), assuming the Seller is not a Person with which CEMEX
consolidated or into which CEMEX merged or which merged into CEMEX, or to which
such sale or transfer was made, as the case may be (a "Constituent Person"), or
an Affiliate of a Constituent Person, and failed to exercise his right of
election, if any, as to the kind or amount of securities, cash or other property
receivable upon such consolidation, merger, reclassification, conveyance,
transfer or sale (provided that if the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer is
not the same for each CPO in respect of which such rights of election shall not
have been exercised ("non-electing share"), then for the purpose of this Article
I(5) the kind and amount of securities, cash and other property receivable upon
such consolidation, merger, sale or transfer by each non-electing share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
non-electing shares).

CEMEX or the person formed by such consolidation or resulting from
such merger or which acquired such assets or CEMEX's shares, as the case may be,
shall execute and deliver to the Seller a notice setting forth the Seller's
rights as provided above. Such notice shall provide for adjustments which, for
events subsequent to the effective date of such notice, shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
I(5). The above provisions of this Article I(5) shall similarly apply to
successive transactions of the foregoing type.

ARTICLE II

REPRESENTATIONS AND WARRANTIES OF SELLER
----------------------------------------

The Seller hereby represents and warrants to CEMEX as follows:

1.   Corporate Organization. The Seller is a limited partnership duly
organized, validly existing and in good standing under the laws of Bermuda and
has all necessary power and authority to carry on its business as it is now
being conducted and to own the properties and assets it now owns and is
qualified or licensed to do business as a foreign limited partnership in every

2.   Authorization. The Seller has all necessary power and authority
to enter into the Transaction Documents and to carry out the transactions on its
part contemplated thereby. The Seller has taken all actions required by law, its
charter documents or otherwise to be taken by it to authorize the execution and
delivery of the Transaction Documents and the consummation of the transactions
on its part contemplated thereby. Each of the Transaction Documents and any
other instrument to be executed and delivered by the Seller at the Closing or on
any Subsequent Closing Date is, or will be when executed and delivered, the
valid and binding agreement of the Seller enforceable against it in accordance
with its terms, except to the extent that (i) such validity, binding effect or
enforceability may be subject to bankruptcy, insolvency, reorganization,
moratorium or other similar laws now or hereafter in effect relating to
creditors' rights generally, and (ii) the remedy of specific performance and
injunctive and other forms of equitable relief sought may be subject to
equitable defenses and to the discretion of the court before which any
proceeding therefor may be brought.

3.   No Violation. Neither the execution and delivery of the
Transaction Documents by the Seller nor the consummation by the Seller of the
transactions contemplated thereby, including, without limitation, any short
sales and hedging transactions to be effected by the Seller, will (i) violate
any provision of the organizational documents of the Seller, or (ii) violate,
conflict with, or constitute a default (or an event which, with notice or lapse
of time or both, would constitute a default) under, or result in the termination
of, or permit a third party to terminate the rights of the Seller under, or
accelerate the performance required by, or create or accelerate any rights to
repurchase, rights of first offer or rights of first refusal under, or cause the
acceleration of the maturity of any debt or obligation pursuant to, or result in
the creation or imposition of any security interest, lien or other encumbrance
upon any property of the Seller under any agreement or commitment to which it is
a party, or (iii) violate any statute or law or any judgment, decree, order,
regulation or rule of any court or governmental authority, except in the case of
each of clauses (i), (ii) and (iii) where such violations, conflicts, defaults,
terminations or accelerations individually or in the aggregate would not (x)

whole or (y) adversely affect the Seller's ability to perform its obligations
hereunder.

4.   Ownership of Seller's Shares. The Seller is the record and
beneficial owner of all of the Seller's Shares, except to the extent a portion
of the Seller's Shares (i) is held by the Trustee under the Investor Trust
Agreement or (ii) has been transferred pursuant to the terms hereof. On the
Closing Date, the Seller will own the Seller's Shares free and clear of all
liens and encumbrances that would

483742.01-New York S4A                 17

prohibit the sale thereof. On each of the Subsequent Closing Dates, CEMEX (or
its nominee or designee) will acquire good and marketable title to the Number of
Shares purchased by it on such date free and clear of all liens and
encumbrances.

5.   Securities Law Matters. The Seller has conducted its offer and
sale of the Seller's Shares in such a manner that it is not required to register
the offering and sale of such Seller's Shares with any securities regulatory
authority in Singapore, the United States of America or Mexico.

6.   No Registration. The Seller understands and acknowledges
(a) that it must bear the economic risk of its investment in the CPOs and the
underlying A Shares and B Shares (collectively, the "Securities"); (b) that the
Securities have not been registered under the securities laws of any
jurisdiction other than Mexico and are being offered and sold in reliance upon
exemptions provided in applicable securities laws (other than those of Mexico)
for transactions not involving any public offering and, therefore, cannot be
resold or transferred unless they are subsequently registered under applicable
securities laws (other than those of Mexico, as such Mexican registration will
be in effect at the time of delivery of Securities to the Seller) or unless an
exemption from such registration is available; (c) no regulatory authority has
made any finding or determination as to the fairness for investment of the
Securities and no regulatory authority has recommended or endorsed or will
recommend or endorse any such offer or sale; (d) that it is acquiring the
Securities for its own account and not with any view toward a distribution
thereof in violation of any applicable securities laws; (e) that it has no
contract, undertaking, agreement or arrangement with any person to sell,
transfer or pledge to such person or anyone else any of the Securities which it
hereby acquires or any part thereof other than pursuant to the Seller's limited
partnership agreement and in compliance with all applicable securities laws, and
it has no present plans to enter into any such contract, undertaking, agreement
or arrangement other than in compliance with all applicable securities laws; (f)
that CEMEX does not have any obligation or intention to register the Securities
for sale under any securities laws other than under those of Mexico; (g) that,
other than as set forth in Article III(4), the Seller has no right to require
the registration of the Securities under applicable securities laws and
regulations; and (h) the Securities may not be deposited into any unrestricted
depositary receipt facility established or maintained by a depositary bank.

7.   Status of the Seller. The Seller represents and warrants
that either (i) at the time the offer of CPOs was made, at the time of the
Closing and on each Subsequent Closing Date, it was and will be outside the
United States and, at each such time, it was not and will not be a U.S. person
(and was not and will not be

483742.01-New York S4A                 18

purchasing for the account or benefit of a U.S. person) within the meaning of
Regulation S under the U.S. Securities Act of 1933, as amended, or (ii) it is an
"accredited investor" within the meaning of Rule 501(a) under the U.S.
Securities Act of 1933, as amended.

8.   Brokers' Fees. The Seller has no liability or obligation to pay
any fees or commissions to any broker, finder, or agent with respect to the sale
of the Seller's Shares to CEMEX as contemplated by this Agreement.

(a)  The consolidated historical financial statements of CEMEX
and its consolidated subsidiaries, and the related notes thereto, included in
CEMEX's Annual Report on Form 20-F for the fiscal year ended December 31, 2001
(the "2001 Form 20-F"), as filed by CEMEX with the U.S. Securities and Exchange
Commission (the "SEC"), present fairly in all material respects the consolidated
financial position of CEMEX and its consolidated subsidiaries taken together as
a whole as of the dates indicated and the results of their operations and the
changes in their consolidated cash flows for the periods specified; and said
financial statements have been prepared in conformity with Mexican generally
accepted accounting principles applied on a consistent basis throughout the
periods involved (except as otherwise noted therein).

(b)  As of the date of this Agreement, (i) there has been no
change in the consolidated assets, liabilities or financial condition of CEMEX
from that reflected in the 2001 Form 20-F, except for changes in the ordinary
course of business none of which have, singly or in the aggregate, had a
Material Adverse Effect on CEMEX and its subsidiaries taken as a whole, (ii)
other than general economic or political conditions, since the filing of the
2001 Form 20-F, there has been no event causing a Material Adverse Effect as to
CEMEX and its subsidiaries taken as a whole, nor any development that could,
singly or in the aggregate, reasonably be expected to result in a Material
Adverse Effect as to CEMEX and its subsidiaries taken as a whole, and (iii) the
aggregate number of shares of CEMEX Common Stock issued or issuable pursuant to
the exercise of all warrants, options, subscriptions, purchase rights or
conversion or exchange rights in any convertible securities does not materially
exceed the aggregate number of such shares issued or so issuable as reflected in
the consolidated financial statements of CEMEX included in the 2001 Form 20-F,
except, in the case of clauses (i), (ii) and (iii), as disclosed to the Seller
in writing or otherwise publicly disclosed by CEMEX.

(c) The 2001 Form 20-F did not, at the time of its filing with
the SEC, contain an untrue statement of a material fact or omit to state a

483742.01-New York S4A                 22

material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made when the 2001 Form 20-F was so
filed, not misleading.

10.  Contemporaneous Agreements. Contemporaneously with entering into
this Agreement, CEMEX is entering into separate Stock Purchase Agreements
substantively identical to this Agreement (other than in respect to Article
IV(7) and (11) hereof) with each of IONA Investment Pte. Ltd., Pan Asian Cement

withholding expense borne by the Seller and arising from such dividend.

5.   Dividends on CPOs. To the extent that CEMEX makes a
dividend or other distribution in CEMEX Common Stock on the CPOs to be received
by the Seller hereunder, such that the aggregate value (as determined in good
faith by the board of directors of CEMEX (in a manner consistent with any
determination of such value for purposes of Article I(5)) of all dividends or
other distributions made exclusively in CEMEX Common Stock on such CPOs within
the 12 months

483742.01-New York S4A                 24

preceding the date of payment of such dividend or distribution (and including
the value of such distribution), and in respect of which no adjustment in the
Number of CPOs pursuant to Article I(5) has been made, exceeds 5% of the
aggregate weighted average price of such CPOs on the Mexican Stock Exchange on
the date such dividend or distribution is declared, then the amount of CEMEX
Common Stock by which such dividends or distributions exceed 5% shall be for the
benefit of the Seller.

6.   Escrow of Seller's Shares. The Seller and CEMEX will execute and
deliver the Escrow Agreement at Closing.

7.   Amended Shareholders Agreement and Charter. CEMEX and the
Seller each will (and to the extent required, CEMEX will cause Cemex Manila
Investments B.V. and CEMEX's other Affiliates that own shares of CAH to) (i)
take all legally permissible action to cause the director(s) it has appointed to
the Board of Directors of CAH (A) to approve the Amended Shareholders Agreement
and cause CAH to ratify the Amended Shareholders Agreement and agree to be bound
thereby, and (B) to approve the Amended and Restated Charter, (ii) approve and
execute the Amended Shareholders Agreement, and (iii) approve the Amended and
Restated Charter. CEMEX will cause CAH to lodge the Amended and Restated Charter
with the Registrar prior to the first Subsequent Closing Date.

8.   Notice of Developments. Each Party will give prompt written
notice to the other of any material adverse development causing a breach of any
of its own representations, warranties, covenants or agreements contained herein
or in the Escrow Agreement.

9.   General. After the Closing, each of the Parties shall, from
time to time, at the request of the other Party and without further cost or
expense to the Party making the request, execute and deliver (and, if
appropriate, file) or cause to be executed and delivered (and, if appropriate,
filed) such other instruments of conveyance and transfer and other documents
reasonably required to carry out the intent of the Transaction Documents as any
other Party may reasonably request and continue to use reasonable efforts to
obtain any consents, approvals, authorizations and waivers necessary in order to
more effectively consummate the transactions contemplated herein and therein.

10.  Confidentiality. The Seller will treat and hold as such all
Confidential Information (as defined below), refrain from using any Confidential
Information except in connection with this Agreement, and deliver promptly to
CEMEX or destroy, at the request and option of CEMEX, all tangible embodiments

483742.01-New York S4A                 25

(and all copies) of Confidential Information that are in its possession;
provided, however, that Seller may share such Confidential Information on an as
needed basis with its officers, Affiliates, limited partners and legal and
financial advisers if such officers, Affiliates, limited partners and advisers
are instructed by the Seller to treat and hold as such all Confidential
Information. If the Seller is required under law, regulation or legal process to
disclose any Confidential Information, the Seller may disclose such Confidential
Information as is so required to be disclosed. In the event that the Seller is
requested or required to disclose any Confidential Information, the Seller will
notify CEMEX promptly of the request or requirement. For purposes hereof,
"Confidential Information" means any information received from CEMEX, CAH or any
of their respective representatives or Affiliates concerning the businesses and
affairs of CAH that is not already generally available to the public. In any
event, the aforesaid confidential obligations do not apply to any Confidential
Information that is in the public domain other than as a result of the Seller's
breach of undertaking herein, or in relation to any Confidential Information
that has been given to the Seller by a third party who is not known to the
Seller to be in breach of any obligation of secrecy to CEMEX or to any
Confidential Information already in Seller's free possession at the time of
disclosure by CEMEX, CAH or any of their respective Affiliates.

11.  Ownership of Seller's Shares; Resignation of Director. For
the avoidance of doubt, CEMEX and the Seller acknowledge and agree that pursuant
to Section 4.1(a) of the Amended Shareholders Agreement, notwithstanding the
delivery of the Seller's Shares to the Escrow Agent as contemplated by the
Transaction Documents, the Seller shall be deemed to "own" the Seller's Shares
held by the Escrow Agent for purposes of Section 4.1(a) of the Amended
Shareholders Agreement; provided, that the Seller shall not be deemed to "own"
any Seller's Shares transferred to CEMEX (or its nominee or designee) on a
Subsequent Closing Date. The Seller agrees to cause the director it has
appointed to the Board of Directors of CAH to resign effective as of 5:00 pm New
York City time on the Closing Date and to waive its right to appoint such
director until the earlier of (i) such time as it is no longer entitled to elect
a director to the Board of Directors of CAH under Section 4.1(a) of the Amended
Shareholders Agreement or (ii) the termination of this Agreement.

12.  Subsequent Modification. If at any time or from time to
time after the date hereof and prior to the final Subsequent Closing Date, CEMEX
or any of its Affiliates shall have entered into an agreement or understanding
relating to the acquisition of or other payment in respect to (whether for cash
or other consideration, and whether pursuant to any form of option, call, put,
purchase, redemption,

483742.01-New York S4A                 26

exchange, retirement or other right) shares of common stock of CAH from a
stockholder other than the Seller, and the terms of such other agreement or
understanding are more favorable to such stockholder than the terms hereof or
the Escrow Agreement are to the Seller, then, within thirty (30) days of the
date of such other agreement or understanding, CEMEX shall provide to Seller a
written description of such other agreement or understanding and provide Seller
a period of at least thirty (30) days in which to decide whether or not to
modify the terms hereof or of the Escrow Agreement to reflect the terms of such
other agreement or understanding (including, without limitation, a change in the
amounts used to calculate the Number of CPOs in Article I(2) hereof).

13.  No Other Transfer of Seller's Shares.

(a)  CEMEX hereby consents to the transfer and release of all of
the Seller's Shares held of record by the Trustee under the Investor Trust
Agreement for purposes of the transactions contemplated in this Agreement;
provided, however, that if the sale of all the Seller's Shares to CEMEX
contemplated hereby is not consummated, then the Seller shall promptly redeposit
50% of such unsold Seller's Shares with the Trustee under the Investor Trust
Agreement.

(b)  The Seller agrees that, except as expressly permitted by
this Agreement or the Transaction Documents, it will not (i) sell, assign (by
operation of law or otherwise) or otherwise dispose of, or grant any option with
respect to, any of the Seller's Shares, or (ii) create or suffer to exist any
lien, security interest, option or other charge or encumbrance upon or with
respect to any of the Seller's Shares.

purposes under the Transaction Documents, and references to such Subsequent
Closing Date shall be deemed to be references to such Early Subsequent
Closing Date.

(c)  If at any time or from time to time after the date hereof
and prior to the final Subsequent Closing Date, CEMEX designates an Early
Subsequent Closing Date in respect to the Seller's Shares in accordance
with the foregoing, or in respect to the shares of CAH to be acquired by
CEMEX in accordance with those separate Stock Purchase Agreements referred
to in the first sentence of Section 6 of this Amendment No. 2, CEMEX shall
contemporaneously designate the same Early Subsequent Closing Date for such
other holders of CAH shares and the Seller, as applicable."

Section 3.  Consideration for Extension. In addition to the Number of CPOs
and/or the Acquisition Amount to be delivered by CEMEX in consideration for the
Seller's Shares from time to time, CEMEX agrees to pay to the Seller in arrears
on each Payment Date an amount equal to the Base Deferral Fee, and any other
amount due hereunder, in accordance with the following:

(a)  Base Deferral Fee Rate. The Base Deferral Fee on the Outstanding
Base Amount shall accrue at a rate (the "Base Deferral Fee Rate") equal to
twelve percent (12%) per annum, commencing as of March 31, 2003.

(b)  Payment of Base Deferral Fee. CEMEX promises to pay to the
Seller, in arrears, the Base Deferral Fee and other amounts due hereunder on
each Payment Date.

(c)  Default Fee. If CEMEX fails to pay any amount when due hereunder,
whether of the Base Deferral Fee or otherwise, and whether due to acceleration
or otherwise, CEMEX shall pay to the Seller a fee (the "Default Fee") on such
amount for each day such past due amount remains unpaid, payable on demand, at
the rate equal to the sum of (i) the Base Deferral Fee Rate, plus (ii) two
percent (2%) per annum.

future taxes, levies, imposts, stamp or other duties, fees, assessments,
deductions, withholdings, other governmental charges, and liabilities
(including penalties and interest) with respect thereto imposed by any
governmental authority (collectively, "Taxes"). If CEMEX is prohibited by
law from making any such payments to the Seller hereunder free and clear of
any such offsets, deductions, withholdings and payments, then (A) CEMEX
shall pay the full amount required to be offset, deducted, withheld or paid
to the relevant governmental authority in accordance with all applicable
laws and (B) the amount which CEMEX is required to pay to the Seller shall
be increased by such additional amount as may be necessary in order that
the actual amount received by the Seller after such offset, deduction,
withholding or payment of Taxes (including offsets, deductions,
withholdings and payments applicable to additional sums payable to the
Seller under this Section 3(d)) shall equal the full amount intended to be
payable to the Seller hereunder.

(ii) The Seller shall notify CEMEX in writing of any payment of
Taxes required or requested of the Seller, and CEMEX shall pay such Taxes
to the relevant governmental authority in accordance with all applicable
laws; provided, however, that if the Seller provides written notice to
CEMEX that such Taxes have been paid by the Seller, CEMEX shall pay or
reimburse and indemnify the Seller therefor within thirty (30) days of
receipt of such notice. CEMEX shall furnish the Seller with the original or
a certified copy of the receipt evidencing payment of any Taxes by CEMEX
pursuant to this Section 3(d) together with any other information that the
Seller may reasonably request to establish to its satisfaction that full
and timely payment of such Taxes has been made.

(e)  Currency and Place of Payment. All payments hereunder shall be
made in Dollars in immediately available and freely transferable funds without
any offset, withholding, or deduction for Taxes or currency conversion costs,
and shall be received by the Seller no later than 2:00 p.m. (Washington, D.C.

represents and warrants to CEMEX as follows:

(a)  Corporate Organization. Seller is a limited partnership duly
organized, validly existing and in good standing under the laws of Bermuda and
has all necessary power and authority to carry on its business as it is now
being conducted and to own the properties and assets it now owns and is
qualified or licensed to do business as a foreign limited partnership in every
jurisdiction in which it is required to so qualify and in which the failure to

sjdc-1275145.19

would have a Material Adverse Effect on the business, results of operations or
financial condition of Seller and its subsidiaries taken as a whole.

(b)  Authorization. The Seller has all necessary power and authority
to enter into the Amendments and to carry out the transactions on its part
contemplated thereby. The Seller has taken all actions required by law, its
charter documents or otherwise to be taken by it to authorize the execution and
delivery of the Amendments and the consummation of the transactions on its part
contemplated thereby. Each of the Amendments and any other instrument to be
executed and delivered by the Seller on the date hereof and at any Subsequent
Closing Date is, or will be when executed and delivered, the valid and binding
agreement of the Seller enforceable against it in accordance with its terms,
except to the extent that (i) such validity, binding effect or enforceability
may be subject to bankruptcy, insolvency, reorganization, moratorium or other
similar laws now or hereafter in effect relating to creditors' rights generally,
and (ii) the remedy of specific performance and injunctive and other forms of
equitable relief sought may be subject to equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought.

(c)  No Violation. Neither the execution and delivery of the
Amendments by the Seller nor the consummation by the Seller of the transactions
contemplated thereby, will (i) violate any provision of the organizational
documents of the Seller, or (ii) violate, conflict with, or constitute a default
(or an event which, with notice or lapse of time or both, would constitute a
default) under, or result in the termination of, or permit a third party to
terminate the rights of the Seller under, or accelerate the performance required
by, or create or accelerate any rights to repurchase, rights of first offer or
rights of first refusal under, or cause the acceleration of the maturity of any
debt or obligation pursuant to, or result in the creation or imposition of any
security interest, lien or other encumbrance upon any property of the Seller
under any agreement or commitment to which it is a party, or (iii) violate any
statute or law or any judgment, decree, order, regulation or rule of any court
or governmental authority, except in the case of each of clauses (i), (ii) and
(iii) where such violations, conflicts, defaults, terminations or accelerations
individually or in the aggregate would not (x) have a Material Adverse Effect on
the Seller and its subsidiaries taken as a whole or (y) adversely affect the
Seller's ability to perform its obligations hereunder.

Section 5.   Representations and Warranties of CEMEX. CEMEX hereby
represents and warrants to the Seller as follows:

(a)  Corporate Organization. CEMEX is a corporation duly organized,
validly existing and in good standing under the laws of Mexico and has all
necessary power and authority to carry on its business as it is now being
conducted and to own the properties and assets it now owns and is qualified or
licensed to do business as a foreign corporation in every jurisdiction in which
it is required to so qualify and in which the failure to so qualify would have a
Material Adverse Effect on the business, results of operations or financial
condition of CEMEX and its subsidiaries taken as a whole.

(b)  Authorization. CEMEX has all necessary power and authority to
enter into the Amendments and to carry out the transactions on its part
contemplated thereby.

sjdc-1275145.19
10

CEMEX has taken all actions required by law, its charter documents or otherwise
to be taken by it to authorize the execution and delivery of the Amendments and
the consummation of the transactions on its part contemplated thereby. Each of
the Amendments and any other instrument to be executed and delivered by CEMEX on
the date hereof and at any Subsequent Closing Date is, or will be when executed
and delivered, the valid and binding agreement of CEMEX enforceable against it
in accordance with its terms, except to the extent that (i) such validity,
binding effect or enforceability may be subject to bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally, and (ii) the remedy of specific
performance and injunctive and other forms of equitable relief sought may be
subject to equitable defenses and to the discretion of the court before which
any proceeding therefor may be brought. CEMEX's obligations hereunder will rank
not less than pari passu with all of CEMEX's other unsecured Debt and
obligations.

(c)  No Violation. Neither the execution and delivery of the
Amendments by CEMEX nor the consummation by CEMEX of the transactions
contemplated hereby, including, should CEMEX so elect, the delivery to the
Escrow Agent of the Acquisition Amount and the acquisition and deposit to the
Seller's Depositary Account of the Number of CPOs, will (i) violate any
provision of its charter documents, or (ii) violate, conflict with, or
constitute a default (or an event which, with notice or lapse of time or both,
would constitute a default) under, or result in the termination of, or permit a
third party to terminate its rights under, or accelerate the performance
required by, or create or accelerate any rights to repurchase, rights of first
offer or rights of first refusal under, or cause the acceleration of the
maturity of any debt or obligation pursuant to, or result in the creation or
imposition of any security interest, lien or other encumbrance upon any property
of CEMEX under, any agreement or commitment to which CEMEX is a party, or (iii)
violate any statute or law or any judgment, decree, order, regulation or rule of
any court or governmental authority, except in the case of each of clauses (i),
(ii) and (iii) where such violations, conflicts, defaults, terminations or

Adverse Effect on CEMEX and its subsidiaries taken as a whole or (y) adversely
affect CEMEX's ability to perform its obligations hereunder.

(d)  Financial Statements and Disclosures.

(i)   The consolidated historical financial statements of CEMEX
and its consolidated subsidiaries, and the related notes thereto, filed by

December 31, 2002 (the "Financial Statements") present fairly in all
material respects the consolidated financial position of CEMEX and its
consolidated subsidiaries taken together as a whole as of the dates
indicated and the results of their operations and the changes in their
consolidated cash flows for the periods specified; and said Financial
Statements have been prepared in conformity with generally accepted
accounting principles in Mexico applied on a consistent basis throughout
the periods involved (except as otherwise noted therein).

11

CEMEX and its subsidiaries taken as a whole, (B) other than general
economic or political conditions, since the filing of the Financial
Statements, there has been no event causing a Material Adverse Effect as to
CEMEX and its subsidiaries taken as a whole, nor any development that
could, singly or in the aggregate, reasonably be expected to result in a
Material Adverse Effect as to CEMEX and its subsidiaries taken as a whole,
and (C) the aggregate number of shares of CEMEX Common Stock issued or
issuable pursuant to the exercise of all warrants, options, subscriptions,
purchase rights or conversion or exchange rights in any convertible
securities does not materially exceed the aggregate number of such shares
issued or so issuable as reflected in the Financial Statements except, in
the case of clauses (A), (B) and (C), as disclosed to the Seller in writing
or otherwise publicly disclosed by CEMEX.

(iii) The Financial Statements did not, at the time of their
filing with the MSE, contain an untrue statement of a material fact or omit
to state a material fact necessary in order to make the statements therein,
in the light of the circumstances under which they were made when they were
so filed, not misleading.

(i)   there is not pending any Insolvency Proceeding with regard to
CEMEX or any Material Subsidiary of CEMEX,

(ii)  no decree or order for relief in respect of CEMEX or any
Material Subsidiary of CEMEX has been entered in any Insolvency Proceeding,
and

respect of CEMEX or any Material Subsidiary of CEMEX in any Insolvency
Proceeding,

Proceeding seeking reorganization, concurso mercantil, or relief under
any applicable law of Mexico, the United States of America or other

action.

13

in each case contemplated by clauses (i) and (ii) above, without any other

(i)   Both Parties may terminate this Agreement by mutual
written consent;

to cure within a reasonable period of time;

written notice to each other Party if the Closing has not occurred by
the close of business on (A) October 15, 2002, unless both Parties
elect in writing to extend

sjdc-1275145.19
16

the date for Closing in accordance with this Article VI(15)(a)(iii),
or (B) if said extension occurs, the date as to which Closing has been
extended in accordance herewith (provided, however, that the right to
terminate this Agreement under this Article VI(15)(a)(iii) shall not
be available to any Party whose failure to fulfill any obligation of
such Party under this Agreement has been the cause of or resulted in
the failure of the transactions contemplated herein to be completed on
or before such date);

(iv)   Either Party may terminate this Agreement by giving
written notice to each other Party if the first Subsequent Closing
Date has not occurred by the close of business on (A) March 31, 2004,
unless both Parties elect in writing to extend the date for such
Subsequent Closing Date in accordance with this Article VI(15)(a)(iv),
or (B) if said extension occurs, the date as to which such Subsequent
Closing Date has been extended in accordance herewith (provided,
however, that the right to terminate this Agreement under this Article
VI(15)(a)(iv) shall not be available to any Party whose failure to
fulfill any obligation of such Party under this Agreement has been the
cause of or resulted in the failure of the transactions contemplated
herein to be completed on or before such date); and

(v)   Either Party may terminate this Agreement by giving
written notice to the other Party if a court of competent jurisdiction
or other governmental authority has issued a final order, decree or
ruling, or taken any other action, having the effect of permanently
restraining, enjoining or otherwise prohibiting any of the
transactions contemplated herein, and all appeals with respect to such
order, decree, ruling or action have been exhausted or the time for
appeal of such order, decree, ruling or action shall have expired.

(b)  In the event of the termination of this Agreement pursuant
to Article VI(15)(a), written notice thereof shall promptly be given to the

satisfy the conditions precedent to the Closing or any Subsequent Closing
Date that has not yet occurred shall terminate, and the transactions
contemplated hereby and thereby shall be abandoned without further action

Section 13.  Miscellaneous Provisions.

(a)  Expenses. All reasonable expenses, including legal fees, incurred
by either Party in connection with the Amendments shall be borne by CEMEX, which
shall promptly upon request reimburse the Seller for such amounts.

(b)  Counterparts. This Amendment No. 2 may be executed simultaneously
in two or more counterparts, each of which shall be deemed an original, but all
of which together shall constitute one and the same instrument.

(c)  Headings. The headings of the Sections of this Amendment No. 2
are inserted for convenience only and shall not constitute a part thereof or
affect in any way the meaning or interpretation of this Amendment No. 2.

(d)  Severability. Each of the representations and undertakings in
this Amendment No. 2 shall be construed separately and severably; if, in any
judicial proceeding, a court shall refuse to enforce any of the provisions
included in any paragraph or subparagraph of this Amendment No. 2, then the
remaining provisions shall be deemed separate and shall continue in full force
and effect.

(e)  CPO Certificate. The Parties agree that this Amendment No. 2
supersedes the CPO Certificate dated March 17, 2003 delivered by CEMEX to the
Seller pursuant to the SPA and that such CPO Certificate shall therefore be of
no force and effect between the Parties.

(f)  International Transaction. This is an international transaction
in which the specification of Dollars is of the essence, and such currency shall
be the currency of account in all events. The payment obligations of CEMEX
hereunder shall not be discharged by payment in another currency, whether
pursuant to a judgment or otherwise, to the extent that the amount so paid on
prompt conversion to Dollars in the United States of America under normal
banking procedures does not yield the amount of Dollars then due. In the event
that any payment by CEMEX, whether pursuant to a judgment or otherwise, upon
conversion and transfer, does not result in the full payment of such amount of
Dollars at the place such amount is due, the Seller shall be entitled to demand
immediate payment of, and shall have a separate cause of action against CEMEX
for, the additional amount necessary to yield the full amount of Dollars then
due. In the event the Seller, upon the conversion of such judgment into Dollars,
shall receive, as a result of currency exchange rate fluctuations, an amount
greater than that to which it was entitled, CEMEX shall be entitled to immediate
reimbursement of the excess amount.

Section 14.  No Other Changes. Except as expressly amended hereby, all
other provisions of the SPA shall remain in full force and effect.

AMENDMENT NO. 3
TO STOCK PURCHASE AGREEMENT

This AMENDMENT NO. 3, dated as of July 15, 2003 ("Amendment
No. 3"), between CEMEX, S.A. de C.V., a corporation organized under the laws of
the United Mexican States ("CEMEX"), and AIG ASIAN INFRASTRUCTURE FUND II LP, a
limited partnership organized under the laws of Bermuda (the "Seller"), to the
Stock Purchase Agreement, dated as of July 12, 2002 (the "Original Agreement"),
between CEMEX and the Seller, as amended by (i) the Letter Agreement and Waiver,
dated as of March 18, 2003 ("Amendment No. 1"), and (ii) Amendment No. 2 to
Stock Purchase Agreement, dated as of April 3, 2003 ("Amendment No. 2; and the
Original Agreement, as amended by Amendment No. 1 and Amendment No. 2, the
"Agreement"), each between CEMEX and the Seller, amends the Agreement as set
forth herein. Capitalized terms used herein and not otherwise defined shall have
the meanings ascribed to such terms in the Agreement.

NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties and covenants herein contained, the receipt and
adequacy of which are hereby acknowledged, and intending legally to be bound
hereby, CEMEX and the Seller agree as follows:

1.       The first sentence of Article I(5) of the Agreement is hereby
amended in its entirety to read as follows:

"5. Adjustments to the Number of CPOs. The Number of
CPOs to be delivered on any Subsequent Closing Date shall be
adjusted from time to time as set forth in this Article I(5);
provided, however, that with respect to any Tranche (i) no
adjustment shall be made for any dividend or other
distribution paid or made on the CEMEX Common Stock after the
Original Subsequent Closing Date for such Tranche if the
aggregate value (as determined in good faith by the board of
directors of CEMEX) of all dividends or other distributions
paid or made on the CEMEX Common Stock from the date
immediately following the Original Subsequent Closing Date for
such Tranche until and including the Subsequent Closing Date
for such Tranche (and including the value of such dividend or
distribution) does not exceed 5% of the current market
capitalization (determined as provided in paragraph (g) of
this Article I(5)) of the CEMEX Common Stock on the date fixed
for the determination of stockholders entitled to receive such
dividend or distribution, and (ii) if a dividend or other
distribution is paid or made on the CEMEX Common Stock after
the Original Subsequent Closing Date for such Tranche and the
aggregate value (as determined in good faith by the board of
directors of CEMEX) of all dividends or other distributions
paid or made on the CEMEX Common Stock from the date
immediately following the Original Subsequent Closing Date for
such Tranche until and including the

Subsequent Closing Date for such Tranche (and including the
value of such dividend or distribution) (such aggregate value,
being referred to as the "Aggregate Value") exceeds 5% of the
current market capitalization (determined as provided in
paragraph (g) of this Article I(5)) of the CEMEX Common Stock
on the date fixed for the determination of stockholders
entitled to receive such dividend or distribution (such 5% of
the current market capitalization, being referred to as the
"Dividend Cap"), then the Number of CPOs to be delivered on
the Subsequent Closing Date for such Tranche shall be adjusted
as set forth in this Article I(5) as if such dividend or other
distribution consisted of a dividend or distribution of only
such portion of such dividend or distribution as has a value
(determined in the same manner as the Aggregate Value referred
to above is determined) equal to the amount by which the
Aggregate Value exceeds the Dividend Cap."

2.       Article IV(5) of the Agreement is hereby deleted in its
entirety and amended to read as follows:

"5. OMITTED."

3.       Attached hereto as Exhibit A is a detailed calculation showing
(i) the increased Number of CPOs which have been adjusted for
the cash and stock portion of the dividend paid by CEMEX on
June 5, 2003, and (ii) the Base Deferral Fee payment schedule
as of the date hereof.

4.       This Amendment No. 3 may be executed simultaneously in two or
more counterparts, each of which shall be deemed an original,
but all of which together shall constitute one and the same
instrument.

5.       Except as expressly amended hereby, all other provisions of
the Agreement shall remain in full force and effect.

6.       THIS AMENDMENT NO. 3 AND ALL RIGHTS AND REMEDIES AMONG CEMEX
AND THE SELLER SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO ITS CONFLICTS OF LAW DOCTRINE OTHER THAN NEW YORK

PAN ASIAN CEMENT INVESTORS LP

483745.01-New York S4A

STOCK PURCHASE AGREEMENT, dated as of July 12, 2002 (the "Agreement"),
between CEMEX, S.A. de C.V., a corporation organized under the laws of the
United Mexican States ("CEMEX"), and PAN ASIAN CEMENT INVESTORS LP, a limited
partnership organized under the laws of the State of Delaware (the "Seller").
The Seller and CEMEX are herein sometimes referred to individually as a "Party"
and collectively as the "Parties."

WITNESSETH:

WHEREAS, the Seller beneficially owns 127,146 shares (the "Seller's
Shares") of common stock of CEMEX Asia Holdings, Ltd. ("CAH");

WHEREAS, this Agreement contemplates a transaction in which CEMEX will
purchase from the Seller, and the Seller will sell to CEMEX, the Seller's
Shares;

WHEREAS, subject to the terms and conditions set forth herein, on or
before each Subsequent Closing Date (as hereinafter defined), CEMEX will deliver
or cause to be delivered to the Seller (or the Seller's designee) either (i)
CEMEX Ordinary Participation Certificates ("CPOs"), each CPO representing two
shares of series A common stock ("A Shares") and one share of series B common
stock ("B Shares" and, together with the A Shares, the "CEMEX Common Stock") of
CEMEX or (ii) cash sufficient to purchase the Number of CPOs (as hereinafter
defined), as consideration for the Number of Shares (as hereinafter defined);

WHEREAS, this Agreement sets forth the terms and conditions upon which
the Seller will sell such Seller's Shares to CEMEX; and

WHEREAS, subject to the terms and conditions set forth herein, CEMEX
and the Seller have agreed to enter into (i) an Escrow Agreement by and among
CEMEX, the Seller, and JPMorgan Chase Bank, as escrow agent (the "Escrow
Agent"), to be dated on or prior to the Closing Date (as defined herein),
substantially in the form attached hereto as Exhibit A (the "Escrow Agreement"),
and (ii) a Third Amended and Restated Shareholders Agreement, to be dated on or
prior to the Closing Date, substantially in the form attached hereto as Exhibit
B (the "Amended Shareholders Agreement" and, together with this Agreement and
the Escrow Agreement, the "Transaction Documents"). Capitalized terms used but
not

483745.01-New York S4A

defined herein shall have the respective meanings given to them in the Amended
Shareholders Agreement.

NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties and covenants herein contained, intending to be
legally bound hereby, the Parties agree as follows:

ARTICLE I

PURCHASE AND SALE OF SELLER'S SHARES
------------------------------------

1.   Basic Transaction. (a) On and subject to the terms and conditions
of this Agreement and the Escrow Agreement, on March 31, 2003, June 30, 2003,
September 30, 2003 and December 31, 2003 (or if any such day is not a business
day in each of New York, Mexico and Singapore (a "Business Day"), then the first
day thereafter that is a Business Day)(each a "Subsequent Closing Date"), CEMEX
agrees to purchase from the Seller, and the Seller agrees to sell to CEMEX, the
number of Seller's Shares set forth in the column corresponding to such
Subsequent Closing Date opposite the Seller's name on Schedule A to the Escrow
Agreement (such number of Seller's Shares to be sold on a Subsequent Closing
Date being referred to herein as the "Number of Shares").

(b)  Notwithstanding anything to the contrary contained in the
foregoing Article I(1)(a), at any time from and after Closing, upon prior
written notice to the Seller and all other parties to the Escrow Agreement,
CEMEX may designate any Business Day after the thirtieth day following such
notice and prior to a Subsequent Closing Date as the "Early Subsequent Closing
Date" for such Subsequent Closing Date. Following any such designation, such
Early Subsequent Closing Date shall be deemed to be the Subsequent Closing Date
for all purposes under the Transaction Documents, and references to such
Subsequent Closing Date shall be deemed to be references to such Early
Subsequent Closing Date.

(c)  If at any time or from time to time after the date hereof
and prior to the final Subsequent Closing Date, CEMEX designates an Early
Subsequent Closing Date in respect to the Seller's Shares, or in respect to the
shares of CAH to be acquired by CEMEX in accordance with those separate Stock
Purchase Agreements referred to in Article III(10), CEMEX shall
contemporaneously designate the same Early Subsequent Closing Date for such
other holders of CAH shares and the Seller, as applicable.

483745.01-New York S4A                 2

2.   Purchase Price. On or before each Subsequent Closing Date, CEMEX
shall deliver or cause to be delivered to the Seller (or its designee), as
consideration for the Number of Shares to be purchased by CEMEX on such
Subsequent Closing Date, either (i) a number of CPOs (the "Number of CPOs")
equal to the product obtained by multiplying such Number of Shares times
U.S.$95.00 and dividing such product by U.S.$4.998, or (ii) an amount (the
"Acquisition Amount") of cash in immediately available United States Dollars
equal to the sum of (A) the purchase price of the Number of CPOs, plus (B) all
transaction costs, including brokerage fees and commissions, currency exchange
costs and other fees and expenses reasonably estimated to be incurred in
connection with the acquisition and deposit of such Number of CPOs to the
Seller's Depositary Account (as defined in the Escrow Agreement); provided,
however, that should CEMEX elect to deliver the Acquisition Amount, then CEMEX
shall, in accordance with Section 5(b)(iv) of the Escrow Agreement, (x) deliver
such cash to the Escrow Agent sufficiently in advance of the relevant Subsequent
Closing Date to permit the Escrow Agent to arrange for the purchase of the
Number of CPOs with such funds, and to have such CPOs available for delivery to
the Seller (or its nominee) on such Subsequent Closing Date, and (y) give
written instructions to the Escrow Agent regarding the procedures for such
purchase; and further provided, however, that CEMEX's obligation to deposit the
Number of CPOs on any Subsequent Closing Date to the Seller's Depositary Account
(as defined in the Escrow Agreement) shall not be satisfied until such Number of
CPOs is so deposited. The Number of CPOs to be delivered on a Subsequent Closing
Date pursuant to the preceding sentence shall be adjusted from time to time as
set forth in Article I(5) below.

3.   Closing. Subject to the conditions set forth in Article V below,
the closing to occur on the Closing Date contemplated by this Agreement (the
"Closing") shall occur at the offices of Skadden, Arps, Slate, Meagher & Flom
LLP, 4 Times Square, New York, NY 10036, at 10:00 am, local time, on July 12,
2002 or at such other time and place, no later than the thirtieth day following
such date, as shall be agreed by the Parties (such date being referred to herein
as the "Closing Date").

483745.01-New York S4A                 3

4.   Deliveries at the Closing.

(a)  At the Closing, subject to the terms and conditions set
forth herein, the Seller will deliver:

(i)   to CEMEX, (A) a counterpart to the Escrow Agreement
and the Amended Shareholders Agreement, each duly executed by the Seller,
and (B) the officer's certificate contemplated by Article V(1)(e);

(ii)  to the Escrow Agent, (A) a counterpart to the Escrow
Agreement, duly executed by the Seller, and (B) the documents and
instruments comprising the Deposit (as defined in the Escrow Agreement);

(iii) a release substantially in the form attached hereto as
Exhibit C (the "Release"), duly executed by the Seller; and

(iv)  all other previously undelivered documents required by
the Transaction Documents to be delivered by the Seller at or prior to the
Closing Date.

(b)  At the Closing, subject to the terms and conditions set
forth herein, CEMEX will deliver to the Seller:

(i)   counterparts to the Escrow Agreement and the Amended
Shareholders Agreement, each duly executed by all of the parties thereto on
their own behalf;

(ii)  the officer's certificate contemplated by Article
V(2)(g);

(iii) a counterpart to the Release delivered by the Seller
pursuant to Section 4(a)(iii), duly executed by CAH;

(iv)  a true and complete copy of the Amended and Restated
Charter of CAH (substantially in the form of Exhibit D attached hereto)
(the "Amended and Restated Charter"), as will be lodged by CAH within 14
days from the Closing Date in the Office of the Registrar of Companies and
Business, Singapore (the "Registrar"), conforming CAH's Charter to the
Amended Shareholders Agreement; and

483745.01-New York S4A                 4

(v)   all other previously undelivered documents required by
the Transaction Documents to be delivered by CEMEX at or prior to the
Closing Date.

5.   Adjustments to the Number of CPOs. The Number of CPOs to be
delivered on any Subsequent Closing Date shall be adjusted from time to time as
set forth in this Article I(5); provided, however, that no adjustment shall be
made for any dividend or other distribution paid to or for the benefit of the
Seller pursuant to Article IV(5) below.

(a)  In case CEMEX shall pay or make a dividend or other
distribution on all or any portion of the CEMEX Common Stock exclusively in
CEMEX Common Stock or shall pay or make a dividend or other distribution on any
other class of capital stock of CEMEX which dividend or distribution includes
CEMEX Common Stock, the Number of CPOs as of the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be increased by multiplying
such Number of CPOs by a fraction of which the denominator shall be the number
of shares of all CEMEX Common Stock outstanding at the close of business on the
date fixed for such determination and the numerator shall be the sum of such
number of shares and the total number of shares of CEMEX Common Stock
constituting such dividend or other distribution, such increase to become
effective immediately after the opening of business on the day following the
date fixed for such determination.

(b)  In case CEMEX shall pay or make a dividend or other
distribution on all or any portion of the CEMEX Common Stock consisting of, or
shall otherwise issue to holders of all or any portion of the CEMEX Common
Stock, rights, warrants or options entitling the holders thereof to subscribe
for or purchase shares of any class of CEMEX Common Stock at a price per share
less than the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date fixed for the
determination of stockholders entitled to receive such rights, warrants or
options (each such class, an "affected class"), the Number of CPOs in effect at
the opening of business on the day following the date fixed for such
determination shall be increased by multiplying such number by a fraction of
which the denominator shall be the number of shares of all CEMEX Common Stock
outstanding at the close of business on the date fixed for such determination
plus, for each affected class, the number of shares of such class which the
aggregate of the offering price of the total number of shares of such class so
offered for subscription or purchase would purchase at such current market price
and the numerator shall be the number of shares of all CEMEX Common Stock
outstand-

483745.01-New York S4A                 5

ing at the close of business on the date fixed for such determination plus, for
each affected class, the number of shares of such class so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination.

(c)  In case all or any portion of the outstanding CEMEX Common
Stock shall be subdivided into a greater number of shares of CEMEX Common Stock,
the Number of CPOs in effect at the opening of business on the day following the
day upon which such subdivision becomes effective shall be proportionately
increased (based on the change in the total number of shares of all CEMEX Common
Stock, without regard to classes), and, conversely, in case all or any portion
of the outstanding CEMEX Common Stock shall be combined into a smaller number of
shares of CEMEX Common Stock, the Number of CPOs in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be proportionately reduced (based on the change in the total
number of shares of all CEMEX Common Stock, without regard to classes), such
increase or reduction, as the case may be, to become effective immediately after
the opening of business on the day following the day upon which such subdivision
or combination becomes effective.

(d)  Subject to the last sentence of this paragraph (d), in case
CEMEX shall, by dividend or otherwise, distribute to holders of all or any
portion of the CEMEX Common Stock evidences of CEMEX's indebtedness, shares of
any class of capital stock, securities, cash or property (excluding any rights,
warrants or options referred to in paragraph (b) of this Article I(5), any
dividend or distribution paid exclusively in cash and any dividend or
distribution referred to in paragraph (a) of this Article I(5)), the Number of
CPOs shall be increased so that the same shall equal the number determined by
multiplying the Number of CPOs in effect immediately prior to the effectiveness
of the increase in the Number of CPOs contemplated by this paragraph (d) by a
fraction of which the denominator shall be the current market capitalization
(determined as provided in paragraph (g) of this Article I(5)) of the CEMEX
Common Stock on the date fixed for such distribution less the fair market value
(as determined in good faith by the board of directors of CEMEX, whose
determination shall be conclusive and shall, in the case of securities being
distributed for which prior thereto there is an actual or when issued trading
market, be no less than the value determined by reference to the average of the
closing prices in such market over the period specified in the succeeding
sentence), on the date of such effectiveness, of the evidences of indebtedness,
shares of capital stock, securities, cash and other property so distributed and
the numerator shall be such current market capitalization, such increase to
become effective immediately prior to the opening of

483745.01-New York S4A                 6

business on the day following the date fixed for the payment of such
distribution (such date being referred to as the "Reference Date"). If the board
of directors of CEMEX determines the fair market value of any distribution for
purposes of this paragraph (d) by reference to the actual or when issued trading
market for any securities comprising such distribution, it must in doing so
consider the prices in such market over the same period used in computing the
current market capitalization pursuant to paragraph (g) of this Article I(5).
For purposes of this paragraph (d), any dividend or distribution that includes
shares of CEMEX Common Stock or rights, warrants or options to subscribe for or
purchase shares of CEMEX Common Stock shall be deemed instead to be (A) a
dividend or distribution of the evidences of indebtedness, cash, shares of
capital stock, other securities or other property other than such shares of
CEMEX Common Stock or such rights, warrants or options (making any increase in
the Number of CPOs required by this paragraph (d)) immediately followed by (B) a
dividend or distribution of such shares of CEMEX Common Stock or such rights,
warrants or options (making any further increase in the Number of CPOs required
by paragraph (a) or (b) of this Article I(5), except (A) the Reference Date of
such dividend or distribution as defined in this paragraph (d) shall be
substituted as "the date fixed for the determination of stockholders entitled to
receive such rights, warrants or options" and "the date fixed for such
determination" within the meaning of paragraphs (a) and (b) of this Article I(5)
and (B) any shares of CEMEX Common Stock included in such dividend or
distribution shall not be deemed "outstanding at the close of business on the
date fixed for such determination" within the meaning of paragraph (a) of this
Article I(5)).

(e)  In case CEMEX shall, by dividend or otherwise, make a
distribution to holders of all or any portion of the CEMEX Common Stock
exclusively in cash in an aggregate amount that, together with (A) the aggregate
amount of any other distributions to holders of all or any portion of the CEMEX
Common Stock made exclusively in cash within the 12 months preceding the date of
payment of such distribution and in respect of which no adjustment in the Number
of CPOs pursuant to this paragraph (e) has been made and (B) the aggregate of
any cash plus the fair market value (as determined in good faith by the board of
directors of CEMEX, whose determination shall be conclusive), as of the
expiration of the tender or exchange offer referred to below, of consideration
payable in respect of any tender or exchange offer by CEMEX or a subsidiary of
CEMEX for all or any portion of the CEMEX Common Stock concluded within the 12
months preceding the date of payment of such distribution and in respect of
which no adjustment in the Number of CPOs pursuant to paragraph (f) of this
Article I(5) has been made, exceeds 12.5% of the current market capitalization
of the CEMEX Common Stock (determined as provided in paragraph (g) of this
Article I(5)) on the date fixed for the determination

483745.01-New York S4A                 7

of stockholders entitled to receive such distribution, the Number of CPOs shall
be increased so that the same shall equal the number determined by multiplying
the Number of CPOs in effect immediately prior to the effectiveness of the
number increase contemplated by this paragraph (e) by a fraction of which the
denominator shall be the current market capitalization of the CEMEX Common Stock
(determined as provided in paragraph (g) of this Article I(5)) on the date fixed
for such distribution less the amount of cash distributed in such distribution
and the numerator shall be such current market capitalization, such increase to
become effective immediately prior to the opening of business on the day
following the date fixed for the payment of such distribution.

(f)  In case a tender or exchange offer made by CEMEX or any
subsidiary of CEMEX for all or any portion of the CEMEX Common Stock shall
expire and such tender or exchange offer shall involve an aggregate
consideration having a fair market value (as determined in good faith by the
board of directors of CEMEX, whose determination shall be conclusive) at the
last time (the "Expiration Time") tenders or exchanges may be made pursuant to
such tender or exchange offer (as it may be amended) that, together with (A) the
aggregate of the cash plus the fair market value (as determined in good faith by
the board of directors of CEMEX, whose determination shall be conclusive), as of
the expiration of the other tender or exchange offer referred to below, of
consideration payable in respect of any other tender or exchange offer by CEMEX
or a subsidiary of CEMEX for all or any portion of the CEMEX Common Stock
concluded within the 12 months preceding the Expiration Time and in respect of
which no adjustment to the Number of CPOs pursuant to this paragraph (f) has
been made and (B) the aggregate amount of any distributions to all holders of
the CEMEX Common Stock made exclusively in cash within the 12 months preceding
the Expiration Time and in respect of which no adjustment to the Number of CPOs
pursuant to paragraph (e) of this Article I(5) has been made, exceeds 12.5% of
the current market capitalization of the CEMEX Common Stock (determined as
provided in paragraph (g) of this Article I(5)) at the Expiration Time
(calculated by treating as outstanding any shares tendered for sale or
exchange), the Number of CPOs shall be increased so that the same shall equal
the number determined by multiplying the Number of CPOs in effect immediately
prior to the Expiration Time by a fraction of which the denominator shall be (i)
the current market capitalization of the CEMEX Common Stock (determined as
provided in paragraph (g) of this Article I(5)) at the Expiration Time
(calculated by treating as outstanding any shares tendered for sale or exchange)
minus (ii) the fair market value (determined as aforesaid) of the aggregate
consideration payable to stockholders pursuant to such tender or exchange offer
based on the acceptance (up to any maximum specified in the terms of the tender
or exchange offer) of all shares validly

483745.01-New York S4A                 8

tendered for sale or exchange and not withdrawn as of the Expiration Time (the
shares deemed so accepted, up to any such maximum, being referred to as the
"Purchased Shares") and the numerator shall be such current market
capitalization at the Expiration Time (calculated by reducing the relevant
number of outstanding shares by the number of Purchased Shares), such increase
to become effective immediately prior to the opening of business on the day
following the Expiration Time.

(g)  For the purpose of any computation under this paragraph and
paragraphs (b), (d) and (e) of this Article I(5), the current market price per
share of any class of CEMEX Common Stock on any date in question shall be deemed
to be the average of the daily Closing Prices (as defined herein) for such class
for the five consecutive Trading Days (as defined herein) selected by CEMEX
commencing not more than 20 Trading Days before, and ending not later than, the
date in question; provided, however, that (A) if the "ex" date (as hereinafter
defined) for any event (other than the issuance or distribution requiring such
computation) that requires an adjustment to the Number of CPOs pursuant to
paragraph (a), (b), (c), (d), (e) or (f) above ("Other Event") occurs on or
after the 20th Trading Day prior to the date in question and prior to the "ex"
date for the issuance or distribution requiring such computation (the "Current
Event"), the Closing Price for such class for each Trading Day prior to the "ex"
date for such Other Event shall be adjusted by multiplying such Closing Price by
the reciprocal fraction by which the Number of CPOs is so required to be
adjusted as a result of such Other Event, (B) if the "ex" date for any Other
Event occurs after the "ex" date for the Current Event and on or prior to the
date in question, the Closing Price for such class for each Trading Day on and
after the "ex" date for such Other Event shall be adjusted by multiplying such
Closing Price by the same fraction by which the Number of CPOs is so required to
be adjusted as a result of such Other Event, (C) if the "ex" date for any Other
Event occurs on the "ex" date for the Current Event, one of those events shall
be deemed for purposes of clauses (A) and (B) of this proviso to have an "ex"
date occurring prior to the "ex" date for the other event, and (D) if the "ex"
date for the Current Event is on or prior to the date in question, after taking
into account any adjustment required pursuant to clause (B) of this proviso, the
Closing Price for such class for each Trading Day on or after such "ex" date
shall be adjusted by adding thereto an amount calculated by dividing (1) the
amount of any cash plus the fair market value on the date in question (as
determined in good faith by the board of directors of CEMEX (in a manner
consistent with any determination of such value for purposes of paragraph (d) or
(e) of this Article I(5)), whose determination shall be conclusive) of the
rights, warrants, options, evidences of indebtedness, shares of capital stock,
securities or other property being distributed by (2) the number of all shares
of CEMEX Common Stock

483745.01-New York S4A                 9

outstanding as of the close of business on the day before such "ex" date. For
the purpose of any computation under paragraph (f) of this Article I(5), the
current market price per share of any class of CEMEX Common Stock on any date in
question shall be deemed to be the average of the daily Closing Prices for the 5
consecutive Trading Days selected by CEMEX commencing on or after the latest
(the "Commencement Date") of (A) the date 20 Trading Days before the date in
question, (B) the date of commencement of the tender or exchange offer requiring
such computation and (C) the date of the last amendment, if any, of such tender
or exchange offer involving a change in the maximum number of shares for which
tenders are sought or a change in the consideration offered, and ending not
later than the date of the Expiration Time of such tender or exchange offer
(which shall occur on a day no earlier than the last of the 5 consecutive
trading days beginning on the Commencement Date); provided, however, that if the
"ex" date for any Other Event (other than the tender or exchange offer requiring
such computation) occurs on or after the Commencement Date and on or prior to
the date of the Expiration Time for the tender or exchange offer requiring such
computation, the Closing Price for such class for each Trading Day prior to the
"ex" date for such Other Event shall be adjusted by multiplying such Closing
Price by the reciprocal fraction by which the Number of CPOs is so required to
be adjusted as a result of such other event. For the purpose of any computation
under paragraph (d), (e) or (f) of this Article I(5), the current market
capitalization of the CEMEX Common Stock on any day shall be deemed to be the
sum of the market values for each class of CEMEX Common Stock on such day. For
each such class, the market value on any day shall be deemed to equal the
current market price per share for such class on such day, multiplied by the
number of shares of such class outstanding on such day; provided that, in
determining such number of outstanding shares on such day, no effect shall be
given to any change in the number of such shares outstanding attributable to any
event for which an adjustment was made to any Closing Price used to determine
such current market price pursuant to clause (B) or (D) of the proviso to the
second preceding sentence and provided, further, that the same 5 Trading Days
shall be used to calculate the current market price for each class of CEMEX
Common Stock. Similarly, in determining the number of shares of all CEMEX Common
Stock outstanding on the relevant date for the purpose of calculating any
adjustment in the Number of CPOs pursuant to paragraph (b) of this Article I(5),
no effect shall be given to any change in the number of such shares outstanding
attributable to any event for which adjustment was made pursuant to such clause
(B) or (D) to any Closing Price used to determine the current market price of an
affected class for the purpose of calculating such adjustment. For purposes of
this paragraph, the term "ex" date, (A) when used with respect to any issuance
or distribution, means, with respect to any class of CEMEX Common Stock, the
first date on which such class trades regular way on the relevant

483745.01-New York S4A                 10

exchange or in the relevant market from which the Closing Price was obtained
without the right to receive such issuance or distribution, (B) when used with
respect to any subdivision or combination of shares of CEMEX Common Stock, means
the first date on which such class trades regular way on such exchange or in
such market after the time at which such subdivision or combination becomes
effective, and (C) when used with respect to any tender or exchange offer means
the first date on which such class trades regular way on such exchange or in
such market after the Expiration Time of such tender or exchange offer.

"Closing Price" means (i) in respect of any class of Common Stock, for
any Trading Day, the last reported sale price, regular way, of such Common Stock
or, in case no such reported sale takes place on such Trading Day, the average
of the reported closing bid and asked prices, regular way, of such Common Stock
on the Mexican Stock Exchange (the Bolsa Mexicana de Valores, S.A. de C.V.) or,
if such Common Stock is not listed or admitted for trading on such exchange, the
average of the reported closing bid and asked prices of such Common Stock as
furnished by any three leading Mexican Stock Exchange member firms selected from
time to time by CEMEX for that purpose and (ii) in respect of any class of CPOs
representing Common Stock for any Trading Day, the last reported sale price,
regular way, of or, in case no such reported sale takes place on such Trading
Day, the average of the reported closing bid and asked prices, regular way, for
such CPOs, on the Mexican Stock Exchange or, if such CPOs are not listed or
admitted for trading on such exchange, the average of the reported closing bid
and asked prices of such CPOs as furnished by any three leading Mexican Stock
Exchange member firms selected from time to time by CEMEX for that purpose.

"Trading Day" means each Monday, Tuesday, Wednesday, Thursday and
Friday, other than any day on which the Mexican Stock Exchange is not open for
trading.

(h)  (i)   In case CEMEX shall issue or sell any shares of any
class of CEMEX Common Stock without consideration or at a price per share less
than 90% of the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date of such issuance
or sale, the Number of CPOs in effect at the opening of business on the day
following the date of such issuance or sale shall be increased by:

(A)  multiplying the Number of CPOs in effect at the close
of business on the day immediately preceding the date of
such issuance or sale by

483745.01-New York S4A                 11

(B)  a fraction, of which

(1)  the numerator shall be the number of shares of
CEMEX Common Stock outstanding at the close of
business on the date immediately preceding such
issuance or sale, plus the number of shares of
CEMEX Common Stock so issued or sold, and

(2)  the denominator shall be the number of shares of
CEMEX Common Stock outstanding at the close of
business on the date immediately preceding such
issuance or sale, plus the number of shares of
CEMEX Common Stock which the aggregate
consideration, if any, received (or to be
received) by CEMEX for the total number of such
additional shares of CEMEX Common Stock so issued
or sold would purchase at such current market
price per share.

(ii)  For the purposes of this Article I(5)(h), the issuance
of any warrants, options, subscriptions, or purchase rights with respect to
shares of any class of CEMEX Common Stock and the issuance of any
securities convertible into or exchangeable for shares of any class of
CEMEX Common Stock (or the issuance of any warrants, options or any rights
with respect to such convertible or exchangeable securities) shall be
deemed an issuance of such shares of such class of CEMEX Common Stock at
such time if the Net Consideration Per Share (as hereinafter determined)
which may be received by CEMEX for such CEMEX Common Stock shall be less
than 90% of the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date of such
issuance. Any obligation, agreement, or undertaking to issue warrants,
options, subscriptions, or purchase rights at any time in the future shall
be deemed to be an issuance at the time such obligation, agreement or
undertaking is made or arises.

483745.01-New York S4A

12

(iii) No adjustment to the Number of CPOs shall be made
under this Article I(5)(h) upon the sale or issuance (or deemed issuance)
of any shares of CEMEX Common Stock pursuant to:

(A) the exercise of any warrants, options, subscriptions, or
purchase rights or the exercise of any conversion or
exchange rights in any convertible securities, in each case,
outstanding as of the close of business on the date hereof;

(B) any employee stock option, purchase or incentive plan,
whether or not existing on the date hereof;

(C) any of the events referred to in paragraphs (a), (b),
(c), (d), (e) and (f) of this Article I(5);

(D) anti-dilution provisions contained in any of the
securities referred to in the preceding clauses (A), (B) and
(C) hereof; or

(E) if any adjustment shall previously have been made, or
deemed not required hereunder, upon the issuance of any such
warrants, options, or subscription or purchase rights or
upon the issuance of any convertible securities (or upon the
issuance of any warrants, options or any rights therefor) as
above provided.

(iv)  If the Net Consideration Per Share of any such
warrants, options, subscriptions, or purchase rights, or convertible
securities is decreased from time to time, then, upon the effectiveness of
each decrease, the Number of CPOs shall be adjusted to such Number of CPOs
as would have obtained (A) had the adjustments made upon the issuance of
such warrants, options, rights, or convertible securities been made upon
the basis of the decreased Net Consideration Per Share of such securities,
and (B) had adjustments made to the Number of CPOs since the date of
issuance of such securities been made to the Number of CPOs as adjusted
pursuant to clause (A) above. Any adjustment of the Number of CPOs with
respect to this paragraph which relates to warrants, options,
subscriptions, purchase rights or

483745.01-New York S4A                 13

convertible securities with respect to shares of CEMEX Common Stock shall
be disregarded if, as, when and to the extent such warrants, options,
subscriptions, purchase rights or convertible securities expire or are
canceled without being exercised or converted, so that the Number of CPOs
effective immediately upon such cancellation or expiration shall be the
same as the Number of CPOs in effect at the time of the issuance of the
expired or canceled warrants, options, subscriptions, purchase rights, or
convertible securities with such additional adjustments as would have been
made to that Number of CPOs had the expired or canceled warrants, options,
subscriptions, purchase rights or convertible securities not been issued.

(v)  "Net Consideration Per Share" shall mean the total
amount of consideration, if any, received by CEMEX as of the date of
issuance in respect to the issuance of such warrants, options,
subscriptions, or other purchase rights or convertible or exchangeable
securities, plus the minimum amount of consideration, if any, payable to
CEMEX upon exercise or conversion thereof, divided by the aggregate number
of shares of CEMEX Common Stock that would be issued if all such warrants,
options, subscriptions, or other purchase rights or convertible or
exchangeable securities were exercised, exchanged, or converted, without
giving effect to any possible future upward price adjustments or rate
adjustments.

(vi)  If part or all of the consideration received by CEMEX
in respect to the issuance of CEMEX Common Stock or of any of the
securities described in this Article I(5)(h) consists of property other
than cash, such consideration shall be deemed to have a fair market value
reasonably determined in good faith by the board of directors of CEMEX.

(i)  No adjustment in the Number of CPOs shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Number of CPOs; provided, however, that any adjustments which by reason of this
paragraph (i) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment.

(j)  In addition to the adjustments in the Number of CPOs
required by paragraphs (a), (b), (c), (d), (e), (f) and (h) of this Article
I(5), CEMEX may from time to time in its discretion make such increases in the
Number of CPOs as it considers to be advisable in order to avoid or diminish any
Mexican income tax to any holders of shares of CEMEX Common Stock resulting from
any dividend or distribution of stock or issuance of rights or warrants to
purchase or subscribe for

483745.01-New York S4A                 14

stock or from any event treated as such for income tax
purposes or for any other reasons.

(k)  For purposes of calculating the number of shares of CEMEX
Common Stock at any time outstanding or the number of shares of CEMEX Common
Stock acquired in any tender or exchange offer, the number of shares of CEMEX
held in its treasury shall not be included.

(l)  CEMEX shall ensure that the time for determining the
stockholders entitled to receive any dividend, issuance or other distribution in
respect of any CEMEX Common Stock, the time of effectiveness of any subdivision
or combination of any CEMEX Common Stock and the expiration time of any tender
or exchange offer made by CEMEX or any subsidiary of CEMEX for any CEMEX Common
Stock shall be at or after the close of business on the date fixed for
determining such stockholders, or on the date of such effectiveness or
expiration, as the case may be, so that (whether or not any adjustment to the
Number of CPOs is required pursuant to this Article I(5)) any Subsequent Closing
Date occurring on such date shall be deemed to have occurred prior to such
relevant time on such date.

(m)  Whenever the Number of CPOs is adjusted as herein provided,
CEMEX shall promptly deliver to the Seller a notice setting forth the adjusted
Number of CPOs and showing in reasonable detail the facts upon which such
adjustment is based.

(n)  In the event that CEMEX shall be a party to any transaction
(including any (i) recapitalization or reclassification of all or any portion of
the CEMEX Common Stock (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination of all or any portion of the CEMEX Common Stock), (ii)
consolidation of CEMEX with, or merger of CEMEX into, any other person, or any
merger of another person into CEMEX (other than a merger which does not result
in a reclassification, conversion, exchange or cancellation of any outstanding
CEMEX Common Stock), (iii) conveyance, transfer, sale or lease of all or
substantially all of the assets of CEMEX, or (iv) compulsory share exchange)
pursuant to which the CPOs are converted into the right to receive other
securities, cash or other property, then lawful provision shall be made as part
of the terms of such transaction providing that the Seller shall have the right
thereafter, to purchase the kind and amount of securities, cash and other
property receivable upon such consolidation,

483745.01-New York S4A                 15

merger, reclassification, conveyance, transfer or sale by a holder of the Number
of CPOs which the Seller was entitled to purchase immediately prior to such
consolidation, merger, reclassification, conveyance, transfer or sale (the
"Transaction Consideration"), assuming the Seller is not a Person with which
CEMEX consolidated or into which CEMEX merged or which merged into CEMEX, or to
which such sale or transfer was made, as the case may be (a "Constituent
Person"), or an Affiliate of a Constituent Person, and failed to exercise his
right of election, if any, as to the kind or amount of securities, cash or other
property receivable upon such consolidation, merger, reclassification,
conveyance, transfer or sale (provided that if the kind or amount of securities,
cash and other property receivable upon such consolidation, merger, sale or
transfer is not the same for each CPO in respect of which such rights of
election shall not have been exercised ("non-electing share"), then for the
purpose of this Article I(5) the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, sale or transfer by each
non-electing share shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares).

CEMEX or the person formed by such consolidation or resulting from
such merger or which acquired such assets or CEMEX's shares, as the case may be,
shall execute and deliver to the Seller a notice setting forth the Seller's
rights as provided above. Such notice shall provide for adjustments which, for
events subsequent to the effective date of such notice, shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
I(5). The above provisions of this Article I(5) shall similarly apply to
successive transactions of the foregoing type.

it is now being conducted and to own the properties and assets it now owns and
is qualified or licensed to do business as a foreign limited partnership in

483745.01-New York S4A                 16

2.   Authorization. The Seller has all necessary power and authority

delivery of the Transaction Documents and the consummation of the transactions
on its part contemplated thereby. Each of the Transaction Documents and any
other instrument to be executed and delivered by the Seller at the Closing or on
any Subsequent Closing Date is, or will be when executed and delivered, the
valid and binding agreement of the Seller enforceable against it in accordance
with its terms, except to the extent that (i) such validity, binding effect or
enforceability may be subject to bankruptcy, insolvency, reorganization,

3.   No Violation. Neither the execution and delivery of the
Transaction Documents by the Seller nor the consummation by the Seller of the
transactions contemplated thereby, including, without limitation, any short
sales and hedging transactions to be effected by the Seller, will (i) violate
any provision of the organizational documents of the Seller, or (ii) violate,
conflict with, or constitute a default (or an event which, with notice or lapse

repurchase, rights of first offer or rights of first refusal under, or cause the
acceleration of the maturity of any debt or obligation pursuant to, or result in
the creation or imposition of any security interest, lien or other encumbrance
upon any property of the Seller under any agreement or commitment to which it is
a party, or (iii) violate any statute or law or any judgment, decree, order,
regulation or rule of any court or governmental authority, except in the case of
each of clauses (i), (ii) and (iii) where such violations, conflicts, defaults,

hereunder.

beneficial owner of all of the Seller's Shares, except to the extent a portion

483745.01-New York S4A                 17

will own the Seller's Shares free and clear of all liens and encumbrances that
would prohibit the sale thereof. On each of the Subsequent Closing Dates, CEMEX
(or its nominee or designee) will acquire good and marketable title to the
Number of Shares purchased by it on such date free and clear of all liens and
encumbrances.

5.   Securities Law Matters. The Seller has conducted its offer and
sale of the Seller's Shares in such a manner that it is not required to register
the offering and sale of such Seller's Shares with any securities regulatory
authority in Singapore, the United States of America or Mexico.

6.   No Registration. The Seller understands and acknowledges (a) that
it must bear the economic risk of its investment in the CPOs and the underlying
A Shares and B Shares (collectively, the "Securities"); (b) that the Securities
have not been registered under the securities laws of any jurisdiction other
than Mexico and are being offered and sold in reliance upon exemptions provided
in applicable securities laws (other than those of Mexico) for transactions not
involving any public offering and, therefore, cannot be resold or transferred
unless they are subsequently registered under applicable securities laws (other
than those of Mexico, as such Mexican registration will be in effect at the time
of delivery of Securities to the Seller) or unless an exemption from such
registration is available; (c) no regulatory authority has made any finding or
determination as to the fairness for investment of the Securities and no
regulatory authority has recommended or endorsed or will recommend or endorse
any such offer or sale; (d) that it is acquiring the Securities for its own
account and not with any view toward a distribution thereof in violation of any
applicable securities laws; (e) that it has no contract, undertaking, agreement

anyone else any of the Securities which it hereby acquires or any part thereof
other than pursuant to the Seller's limited partnership agreement and in
compliance with all applicable securities laws, and it has no present plans to
enter into any such contract, undertaking, agreement or arrangement other than
in compliance with all applicable securities laws; (f) that CEMEX does not have
any obligation or intention to register the Securities for sale under any
securities laws other than under those of Mexico; (g) that, other than as set
forth in Article III(4), the Seller has no right to require the registration of
the Securities under applicable securities laws and regulations; and (h) the
Securities may not be deposited into any unrestricted depositary receipt
facility established or maintained by a depositary bank.

7.   Status of the Seller. The Seller represents and warrants that
either (i) at the time the offer of CPOs was made, at the time of the Closing
and on each Subsequent Closing Date, it was and will be outside the United
States and, at

483745.01-New York S4A                 18

each such time, it was not and will not be a U.S. person (and was not and will
not be purchasing for the account or benefit of a U.S. person) within the
meaning of Regulation S under the U.S. Securities Act of 1933, as amended, or
(ii) it is an "accredited investor" within the meaning of Rule 501(a) under the
U.S. Securities Act of 1933, as amended.

8.   Brokers' Fees. The Seller has no liability or obligation to pay
any fees or commissions to any broker, finder, or agent with respect to the sale
of the Seller's Shares to CEMEX as contemplated by this Agreement.

proceeding therefor may be brought.

3.   No Violation. Neither the execution and delivery of the
Transaction Documents by CEMEX nor the consummation by CEMEX of the transactions

Escrow Agent of the Acquisition Amount and the acquisition and deposit to the
Seller's Depositary Account of the Number of CPOs, will (i) violate any

Adverse Effect on CEMEX and its subsidiaries taken as a whole or (y) adversely
affect CEMEX's ability to perform its obligations hereunder.

4.   CPOs. Any CPOs and any underlying A Shares and B Shares to be

the Seller's Shares have not been registered under the securities laws of any

and, therefore, cannot be resold or transferred unless they are subsequently
registered under applicable securities laws or unless an exemption from such

the time the offer of the Seller's Shares was made, at the time of the Closing
and on each Subsequent Closing Date, it was and will be outside the United
States and, at each such time, it was not and will not be a U.S. person (and was
not and will not be purchasing for the account or benefit of a U.S. person)

meaning of Regulation S under the U.S. Securities Act of 1933, as amended, or

9.   Financial Statements and Disclosures.

(a)  The consolidated historical financial statements of CEMEX
and its consolidated subsidiaries, and the related notes thereto, included in
CEMEX's Annual Report on Form 20-F for the fiscal year ended December 31, 2001
(the "2001 Form 20-F"), as filed by CEMEX with the U.S. Securities and Exchange
Commission (the "SEC"), present fairly in all material respects the consolidated
financial position of CEMEX and its consolidated subsidiaries taken together as
a whole as of the dates indicated and the results of their operations and the
changes in their consolidated cash flows for the periods specified; and said
financial statements have been prepared in conformity with Mexican generally
accepted accounting principles applied on a consistent basis throughout the
periods involved (except as otherwise noted therein).

(b)  As of the date of this Agreement, (i) there has been no
change in the consolidated assets, liabilities or financial condition of CEMEX
from that reflected in the 2001 Form 20-F, except for changes in the ordinary
course of business none of which have, singly or in the aggregate, had a
Material Adverse Effect on CEMEX and its subsidiaries taken as a whole, (ii)
other than general economic or political conditions, since the filing of the
2001 Form 20-F, there has been no event causing a Material Adverse Effect as to
CEMEX and its subsidiaries taken as a whole, nor any development that could,
singly or in the aggregate, reasonably be expected to result in a Material
Adverse Effect as to CEMEX and its subsidiaries taken as a whole, and (iii) the
aggregate number of shares of CEMEX Common Stock issued or issuable pursuant to
the exercise of all warrants, options, subscriptions, purchase rights or
conversion or exchange rights in any convertible securities does not materially
exceed the aggregate number of such shares issued or so issuable as reflected in
the consolidated financial statements of CEMEX included in the 2001 Form 20-F,
except, in the case of clauses (i), (ii) and (iii), as disclosed to the Seller
in writing or otherwise publicly disclosed by CEMEX.

483745.01-New York S4A                 22

(c)  The 2001 Form 20-F did not, at the time of its filing with
the SEC, contain an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made when the 2001 Form 20-F was so
filed, not misleading.

10.  Contemporaneous Agreements. Contemporaneously with entering into
this Agreement, CEMEX is entering into separate Stock Purchase Agreements
substantively identical to this Agreement (other than in respect to Article
IV(7) and (11) hereof) with each of AIG Asian Infrastructure Fund II LP, IONA
Investment Pte. Ltd., and GIMV N.V., who together with the Seller and Orchid
Asia II, L.P. constitute, as of the date hereof, all of the stockholders of CAH
that have elected to sell all or any portion of their shares of common stock of
CAH to CEMEX.

11.  No Liquidation of CAH. Until the later of January 2, 2004 or the
date that no further Seller's Shares remain subject to this agreement, CEMEX
shall not effect or permit any liquidation, merger, consolidation or other
organic change in the organization of CAH.

CPOs to be received hereunder until received, and (ii) not to engage in short
sales, hedges or other derivative transactions (collectively, "Hedge") with
respect to CPOs prior to their receipt; provided, however, that the Seller may,
in accordance with all

applicable securities laws, Hedge a portion of the CPOs which it will acquire
hereunder, as follows:

% of CPOs Remaining
to Be Acquired
Hereunder That
Period                           May Be Hedged
---------------------------------            -------------------
January 1, 2002 - March 31, 2002                              10%
April 1, 2002 - June 30, 2002                               20%

October 1, 2002 and thereafter                               40%

; provided, further, that any such Hedging activities must be conducted in such
a manner as to not require registration under the securities laws of any
jurisdiction (including, without limitation, the United States of America). It
being understood that the Seller may not Hedge more than 40% of the CPOs
remaining to be acquired by it hereunder at any time (which limitation is
exclusive of any CPOs the Seller may have already acquired hereunder).

4.   Dividends on Seller's Shares. All dividends on the Seller's
Shares will be paid by the Seller to CEMEX upon receipt by the Seller. Seller
hereby instructs the paying agent for CAH to pay any such dividends directly to
CEMEX at:

Bank: Citibank International, Plc.
Branch: Madrid, Spain
Swift: CITIESMX
Company: Cemex Manila Investments B.V.
Account: 0008668019

Notwithstanding the foregoing, the Seller may retain such portion of any
dividend on the Seller's Shares to the extent required to discharge any tax or
withholding expense borne by the Seller and arising from such dividend.

5.   Dividends on CPOs. To the extent that CEMEX makes a dividend or
other distribution in CEMEX Common Stock on the CPOs to be received by the
Seller hereunder, such that the aggregate value (as determined in good faith by
the board of directors of CEMEX (in a manner consistent with any determination
of

483745.01-New York S4A                 24

such value for purposes of Article I(5)) of all dividends or other distributions
made exclusively in CEMEX Common Stock on such CPOs within the 12 months
preceding the date of payment of such dividend or distribution (and including
the value of such distribution), and in respect of which no adjustment in the
Number of CPOs pursuant to Article I(5) has been made, exceeds 5% of the
aggregate weighted average price of such CPOs on the Mexican Stock Exchange on
the date such dividend or distribution is declared, then the amount of CEMEX
Common Stock by which such dividends or distributions exceed 5% shall be for the
benefit of the Seller.

6.   Escrow of Seller's Shares. The Seller and CEMEX will execute and
deliver the Escrow Agreement at Closing.

7.   Amended Shareholders Agreement and Charter. CEMEX and the Seller
each will (and to the extent required, CEMEX will cause Cemex Manila Investments
B.V. and CEMEX's other Affiliates that own shares of CAH to) (i) approve and
execute the Amended Shareholders Agreement, and (ii) approve the Amended and
Restated Charter. CEMEX will cause CAH to lodge the Amended and Restated Charter
with the Registrar prior to the first Subsequent Closing Date.

8.   Notice of Developments. Each Party will give prompt written
notice to the other of any material adverse development causing a breach of any
of its own representations, warranties, covenants or agreements contained herein
or in the Escrow Agreement.

9.   General. After the Closing, each of the Parties shall, from time
to time, at the request of the other Party and without further cost or expense
to the Party making the request, execute and deliver (and, if appropriate, file)
or cause to be executed and delivered (and, if appropriate, filed) such other
instruments of conveyance and transfer and other documents reasonably required
to carry out the intent of the Transaction Documents as any other Party may
reasonably request and continue to use reasonable efforts to obtain any
consents, approvals, authorizations and waivers necessary in order to more
effectively consummate the transactions contemplated herein and therein.

10.  Confidentiality. The Seller will treat and hold as such all
Confidential Information (as defined below), refrain from using any Confidential
Information except in connection with this Agreement, and deliver promptly to
CEMEX or destroy, at the request and option of CEMEX, all tangible embodiments
(and all copies) of Confidential Information that are in its possession;
provided, however, that Seller may share such Confidential Information on an as
needed basis

483745.01-New York S4A                 25

with its officers, Affiliates, limited partners and legal and financial advisers
if such officers, Affiliates, limited partners and advisers are instructed by
the Seller to treat and hold as such all Confidential Information. If the Seller
is required under law, regulation or legal process to disclose any Confidential
Information, the Seller may disclose such Confidential Information as is so
required to be disclosed. In the event that the Seller is requested or required
to disclose any Confidential Information, the Seller will notify CEMEX promptly
of the request or requirement. For purposes hereof, "Confidential Information"
means any information received from CEMEX, CAH or any of their respective
representatives or Affiliates concerning the businesses and affairs of CAH that
is not already generally available to the public. In any event, the aforesaid
confidential obligations do not apply to any Confidential Information that is in
the public domain other than as a result of the Seller's breach of undertaking
herein, or in relation to any Confidential Information that has been given to
the Seller by a third party who is not known to the Seller to be in breach of
any obligation of secrecy to CEMEX or to any Confidential Information already in
Seller's free possession at the time of disclosure by CEMEX, CAH or any of their
respective Affiliates.

11.  Ownership of Seller's Shares. For the avoidance of doubt, CEMEX
and the Seller acknowledge and agree that pursuant to Section 4.1(a) of the
Amended Shareholders Agreement, notwithstanding the delivery of the Seller's
Shares to the Escrow Agent as contemplated by the Transaction Documents, the
Seller shall be deemed to "own" the Seller's Shares held by the Escrow Agent for
purposes of Section 4.1(a) of the Amended Shareholders Agreement; provided, that
the Seller shall not be deemed to "own" any Seller's Shares transferred to CEMEX
(or its nominee or designee) on a Subsequent Closing Date.

12.  Subsequent Modification. If at any time or from time to time
after the date hereof and prior to the final Subsequent Closing Date, CEMEX or
any of its Affiliates shall have entered into an agreement or understanding
relating to the acquisition of or other payment in respect to (whether for cash
or other consideration, and whether pursuant to any form of option, call, put,
purchase, redemption, exchange, retirement or other right) shares of common
stock of CAH from a stockholder other than the Seller, and the terms of such
other agreement or understanding are more favorable to such stockholder than the
terms hereof or the Escrow Agreement are to the Seller, then, within thirty (30)
days of the date of such other agreement or understanding, CEMEX shall provide
to Seller a written description of such other agreement or understanding and
provide Seller a period of at least thirty (30) days in which to decide whether
or not to modify the terms hereof or of the Escrow Agreement to reflect the
terms of such other agreement or

483745.01-New York S4A                 26

understanding (including, without limitation, a change in the amounts used to
calculate the Number of CPOs in Article I(2) hereof).

13.  No Other Transfer of Seller's Shares.

(a)  CEMEX hereby consents to the transfer and release of all of
the Seller's Shares held of record by the Trustee under the Investor Trust
Agreement for purposes of the transactions contemplated in this Agreement;
provided, however, that if the sale of all the Seller's Shares to CEMEX
contemplated hereby is not consummated, then the Seller shall promptly redeposit
50% of such unsold Seller's Shares with the Trustee under the Investor Trust
Agreement.

(b)  The Seller agrees that, except as expressly permitted by
this Agreement or the Transaction Documents, it will not (i) sell, assign (by
operation of law or otherwise) or otherwise dispose of, or grant any option with
respect to, any of the Seller's Shares, or (ii) create or suffer to exist any
lien, security interest, option or other charge or encumbrance upon or with

of this Agreement and the Escrow Agreement, on March 31, 2004, June 30,
2004, September 30, 2004 and December 31, 2004 (or if any such day is not a

to be sold on a Subsequent Closing Date being referred to herein as the
"Number of Shares").

foregoing Article I(1)(a), as to the Number of Shares required to be
purchased by CEMEX on June 30, 2004, September 30, 2004 or December 31,
2004, at any time until:

(i)   June 15, 2003 (or if such day is not a Business Day,
then on the next succeeding Business Day), in respect to the Number of

(ii)  September 15, 2003 (or if such day is not a Business

Shares required to be purchased by CEMEX on December 31, 2004;

CEMEX may designate any Business Day prior to the applicable Subsequent
Closing Date as the "Early Subsequent Closing Date" for such Number of
Shares to be purchased. Following any such designation, such Early
Subsequent Closing Date shall when used with respect to the corresponding
Number of CPOs, be deemed to be the Subsequent Closing Date for all
purposes under the Transaction Documents, and references to such Subsequent
Closing Date shall be deemed to be references to such Early Subsequent
Closing Date.

(c)  If at any time or from time to time after the date hereof
and prior to the final Subsequent Closing Date, CEMEX designates an Early
Subsequent Closing Date in respect to the Seller's Shares in accordance
with the foregoing, or in respect to the shares of CAH to be acquired by
CEMEX in accordance with those separate Stock Purchase Agreements referred

whether of the Base Deferral Fee or otherwise, and whether due to acceleration
or otherwise, CEMEX shall pay to the Seller a fee (the "Default Fee") on such
amount for each day such past due amount remains unpaid, payable on demand, at
the rate equal to the sum of (i) the Base Deferral Fee Rate, plus (ii) two
percent (2%) per annum.

to the relevant governmental authority in accordance with all applicable
laws; provided, however, that if the Seller provides written notice to

contemplated thereby. The Seller has taken all actions required by law, its

by, or create or accelerate any rights to repurchase, rights of first offer or

debt or obligation pursuant to, or result in the creation or imposition of any
security interest, lien or other encumbrance upon any property of the Seller
under any agreement or commitment to which it is a party, or (iii) violate any
statute or law or any judgment, decree, order, regulation or rule of any court
or governmental authority, except in the case of each of clauses (i), (ii) and
(iii) where such violations, conflicts, defaults, terminations or accelerations

enter into the Amendments and to carry out the transactions on its part
contemplated thereby.

to be taken by it to authorize the execution and delivery of the Amendments and
the consummation of the transactions on its part contemplated thereby. Each of

the date hereof and at any Subsequent Closing Date is, or will be when executed
and delivered, the valid and binding agreement of CEMEX enforceable against it
in accordance with its terms, except to the extent that (i) such validity,

performance and injunctive and other forms of equitable relief sought may be
subject to equitable defenses and to the discretion of the court before which
any proceeding therefor may be brought. CEMEX's obligations hereunder will rank

obligations.

(a)  Expenses. All reasonable expenses, including legal fees, incurred
by either Party in connection with the Amendments shall be borne by CEMEX, which
shall promptly upon request reimburse the Seller for such amounts.

(b)  Counterparts. This Amendment No. 2 may be executed simultaneously
in  two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same
instrument.

(c)  Headings. The headings of the Sections of this Amendment No. 2
are inserted for convenience only and shall not constitute a part thereof or
affect in any way the meaning or interpretation of this Amendment No. 2.

(d)  Severability. Each of the representations and undertakings in
this Amendment No. 2 shall be construed separately and severably; if, in any
judicial proceeding, a court shall refuse to enforce any of the provisions
included in any paragraph or subparagraph of this Amendment No. 2, then the
remaining provisions shall be deemed separate and shall continue in full force
and effect.

(e)  CPO Certificate. The Parties agree that this Amendment No. 2
supersedes the CPO Certificate dated March 17, 2003 delivered by CEMEX to the
Seller pursuant to the SPA and that such CPO Certificate shall therefore be of
no force and effect between the Parties.

(f)  International Transaction. This is an international transaction
in which the specification of Dollars is of the essence, and such currency shall
be the currency of account in all events. The payment obligations of CEMEX
hereunder shall not be discharged by payment in another currency, whether
pursuant to a judgment or otherwise, to the extent that the amount so paid on
prompt conversion to Dollars in the United States of America under normal
banking procedures does not yield the amount of Dollars then due. In the event
that any payment by CEMEX, whether pursuant to a judgment or otherwise, upon
conversion and transfer, does not result in the full payment of such amount of
Dollars at the place such amount is due, the Seller shall be entitled to demand
immediate payment of, and shall have a separate cause of action against CEMEX
for, the additional amount necessary to yield the full amount of Dollars then
due. In the event the Seller, upon the conversion of such judgment into Dollars,
shall receive, as a result of currency exchange rate fluctuations, an amount
greater than that to which it was entitled, CEMEX shall be entitled to immediate
reimbursement of the excess amount.

Section 14. No Other Changes. Except as expressly amended hereby, all other
provisions of the SPA shall remain in full force and effect.

between CEMEX, S.A. de C.V., a corporation organized under the laws of the
United Mexican States ("CEMEX"), and PAN ASIAN CEMENT INVESTORS, L.P., a limited
partnership organized under the laws of the State of Delaware (the "Seller"), to

Amendment No. 2 to Stock Purchase Agreement, dated as of April 3, 2003
("Amendment No. 2; and the Original Agreement, as amended by Amendment No. 1 and
Amendment No. 2, the "Agreement"), each between CEMEX and the Seller, amends the
Agreement as set forth herein. Capitalized terms used herein and not otherwise
defined shall have the meanings ascribed to such terms in the Agreement.

NOW, THEREFORE, in consideration of the mutual promises, representations,
warranties and covenants herein contained, the receipt and adequacy of which are
hereby acknowledged, and intending legally to be bound hereby, CEMEX and the
Seller agree as follows:

1.   The first sentence of Article I(5) of the Agreement is hereby amended
in its entirety to read as follows:

"5. Adjustments to the Number of CPOs. The Number of CPOs to be
delivered on any Subsequent Closing Date shall be adjusted from time
to time as set forth in this Article I(5); provided, however, that
with respect to any Tranche (i) no adjustment shall be made for any
dividend or other distribution paid or made on the CEMEX Common Stock
on or after the Original Subsequent Closing Date for such Tranche if
the aggregate value (as determined in good faith by the board of
directors of CEMEX) of all dividends or other distributions paid or
made on the CEMEX Common Stock from the Original Subsequent Closing
Date for such Tranche until and including the Subsequent Closing Date
for such Tranche (and including the value of such dividend or
distribution) does not exceed 5% of the current market capitalization
(determined as provided in paragraph (g) of this Article I(5)) of the
CEMEX Common Stock on the date fixed for the determination of
stockholders entitled to receive such dividend or distribution, and
(ii) if a dividend or other distribution is paid or made on the CEMEX
Common Stock on or after the Original Subsequent Closing Date for such
Tranche and the aggregate value (as determined in good faith by the
board of directors of CEMEX) of all dividends or other distributions
paid or made on the CEMEX Common Stock from the Original Subsequent
Closing Date for such Tranche until and including the Subsequent
Closing Date for such Tranche

(and including the value of such dividend or distribution) (such
aggregate value, being referred to as the "Aggregate Value") exceeds
5% of the current market capitalization (determined as provided in
paragraph (g) of this Article I(5)) of the CEMEX Common Stock on the
date fixed for the determination of stockholders entitled to receive
such dividend or distribution (such 5% of the current market
capitalization, being referred to as the "Dividend Cap"), then the
Number of CPOs to be delivered on the Subsequent Closing Date for such
Tranche shall be adjusted as set forth in this Article I(5) as if such
dividend or other distribution consisted of a dividend or distribution
of only such portion of such dividend or distribution as has a value
(determined in the same manner as the Aggregate Value referred to
above is determined) equal to the amount by which the Aggregate Value
exceeds the Dividend Cap."

2.   Article IV(5) of the Agreement is hereby deleted in its entirety and
amended to read as follows:

"5. OMITTED."

3.   Attached hereto as Exhibit A is a detailed calculation showing (i) the
increased Number of CPOs which have been adjusted for the cash and
stock portion of the dividend paid by CEMEX on June 5, 2003, and (ii)
the Base Deferral Fee payment schedule as of the date hereof.

counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

5.   Except as expressly amended hereby, all other provisions of the
Agreement shall remain in full force and effect.

WITNESSETH:

WHEREAS, the Seller beneficially owns 423,818 shares (the "Seller's

and (ii) a Third Amended and Restated Shareholders Agreement, to be dated on or

Shareholders Agreement.

NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties and covenants herein contained, intending to be
legally bound hereby, the Parties agree as follows:

ARTICLE I

PURCHASE AND SALE OF SELLER'S SHARES
------------------------------------

1.   Basic Transaction. (a) On and subject to the terms and conditions
of this Agreement and the Escrow Agreement, on March 31, 2003, June 30, 2003,
September 30, 2003 and December 31, 2003 (or if any such day is not a business
day in each of New York, Mexico and Singapore (a "Business Day"), then the first
day thereafter that is a Business Day)(each a "Subsequent Closing Date"), CEMEX
agrees to purchase from the Seller, and the Seller agrees to sell to CEMEX, the
number of Seller's Shares set forth in the column corresponding to such
Subsequent Closing Date opposite the Seller's name on Schedule A to the Escrow
Agreement (such number of Seller's Shares to be sold on a Subsequent Closing
Date being referred to herein as the "Number of Shares").

(b)  Notwithstanding anything to the contrary contained in the
foregoing Article I(1)(a), at any time from and after Closing, upon prior
written notice to the Seller and all other parties to the Escrow Agreement,
CEMEX may designate any Business Day after the thirtieth day following such
notice and prior to a Subsequent Closing Date as the "Early Subsequent Closing
Date" for such Subsequent Closing Date. Following any such designation, such
Early Subsequent Closing Date shall be deemed to be the Subsequent Closing Date
for all purposes under the Transaction Documents, and references to such
Subsequent Closing Date shall be deemed to be references to such Early
Subsequent Closing Date.

(c)  If at any time or from time to time after the date hereof
and prior to the final Subsequent Closing Date, CEMEX designates an Early
Subsequent Closing Date in respect to the Seller's Shares, or in respect to the
shares of CAH to be acquired by CEMEX in accordance with those separate Stock
Purchase Agreements referred to in Article III(10), CEMEX shall
contemporaneously designate the same Early Subsequent Closing Date for such
other holders of CAH shares and the Seller, as applicable.

483744.01-New York S4A                  2

2.   Purchase Price. On or before each Subsequent Closing Date, CEMEX
shall deliver or cause to be delivered to the Seller (or its designee), as
consideration for the Number of Shares to be purchased by CEMEX on such
Subsequent Closing Date, either (i) a number of CPOs (the "Number of CPOs")
equal to the product obtained by multiplying such Number of Shares times
U.S.$95.00 and dividing such product by U.S.$4.998, or (ii) an amount (the
"Acquisition Amount") of cash in immediately available United States Dollars
equal to the sum of (A) the purchase price of the Number of CPOs, plus (B) all
transaction costs, including brokerage fees and commissions, currency exchange
costs and other fees and expenses reasonably estimated to be incurred in
connection with the acquisition and deposit of such Number of CPOs to the
Seller's Depositary Account (as defined in the Escrow Agreement); provided,
however, that should CEMEX elect to deliver the Acquisition Amount, then CEMEX
shall, in accordance with Section 5(b)(iv) of the Escrow Agreement, (x) deliver
such cash to the Escrow Agent sufficiently in advance of the relevant Subsequent
Closing Date to permit the Escrow Agent to arrange for the purchase of the
Number of CPOs with such funds, and to have such CPOs available for delivery to
the Seller (or its nominee) on such Subsequent Closing Date, and (y) give
written instructions to the Escrow Agent regarding the procedures for such
purchase; and further provided, however, that CEMEX's obligation to deposit the
Number of CPOs on any Subsequent Closing Date to the Seller's Depositary Account
(as defined in the Escrow Agreement) shall not be satisfied until such Number of
CPOs is so deposited. The Number of CPOs to be delivered on a Subsequent Closing
Date pursuant to the preceding sentence shall be adjusted from time to time as
set forth in Article I(5) below.

3.   Closing. Subject to the conditions set forth in Article V below,
the closing to occur on the Closing Date contemplated by this Agreement (the
"Closing") shall occur at the offices of Skadden, Arps, Slate, Meagher & Flom
LLP, 4 Times Square, New York, NY 10036, at 10:00 am, local time, on July 12,
2002 or at such other time and place, no later than the thirtieth day following

4.   Deliveries at the Closing.

(a)  At the Closing, subject to the terms and conditions set

(i)   to CEMEX, (A) a counterpart to the Escrow Agreement
and the Amended Shareholders Agreement, each duly executed by the Seller,
and (B) the officer's certificate contemplated by Article V(1)(e);

(ii)  to the Escrow Agent, (A) a counterpart to the Escrow

(b)  At the Closing, subject to the terms and conditions set
forth herein, CEMEX will deliver to the Seller:

Shareholders Agreement, each duly executed by all of the parties thereto on
their own behalf;

(ii)  the officer's certificate contemplated by Article
V(2)(g);

(iii) a counterpart to the Release delivered by the Seller
pursuant to Section 4(a)(iii), duly executed by CAH;

(iv)  a true and complete copy of the Amended and Restated

483744.01-New York S4A                  4

(v)   all other previously undelivered documents required by
the Transaction Documents to be delivered by CEMEX at or prior to the
Closing Date.

5.   Adjustments to the Number of CPOs. The Number of CPOs to be
delivered on any Subsequent Closing Date shall be adjusted from time to time as
set forth in this Article I(5); provided, however, that no adjustment shall be
made for any dividend or other distribution paid to or for the benefit of the
Seller pursuant to Article IV(5) below.

(a)  In case CEMEX shall pay or make a dividend or other
distribution on all or any portion of the CEMEX Common Stock exclusively in
CEMEX Common Stock or shall pay or make a dividend or other distribution on any
other class of capital stock of CEMEX which dividend or distribution includes
CEMEX Common Stock, the Number of CPOs as of the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be increased by multiplying
such Number of CPOs by a fraction of which the denominator shall be the number
of shares of all CEMEX Common Stock outstanding at the close of business on the
date fixed for such determination and the numerator shall be the sum of such
number of shares and the total number of shares of CEMEX Common Stock
constituting such dividend or other distribution, such increase to become
effective immediately after the opening of business on the day following the
date fixed for such determination.

(b)  In case CEMEX shall pay or make a dividend or other
distribution on all or any portion of the CEMEX Common Stock consisting of, or
shall otherwise issue to holders of all or any portion of the CEMEX Common
Stock, rights, warrants or options entitling the holders thereof to subscribe
for or purchase shares of any class of CEMEX Common Stock at a price per share
less than the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date fixed for the
determination of stockholders entitled to receive such rights, warrants or
options (each such class, an "affected class"), the Number of CPOs in effect at
the opening of business on the day following the date fixed for such
determination shall be increased by multiplying such number by a fraction of
which the denominator shall be the number of shares of all CEMEX Common Stock
outstanding at the close of business on the date fixed for such determination
plus, for each affected class, the number of shares of such class which the
aggregate of the offering price of the total number of shares of such class so
offered for subscription or purchase would purchase at such current market price
and the numerator shall be the number of shares of all CEMEX Common Stock
outstand-

483744.01-New York S4A                  5

ing at the close of business on the date fixed for such determination plus, for
each affected class, the number of shares of such class so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination.

(c)  In case all or any portion of the outstanding CEMEX Common
Stock shall be subdivided into a greater number of shares of CEMEX Common Stock,
the Number of CPOs in effect at the opening of business on the day following the
day upon which such subdivision becomes effective shall be proportionately
increased (based on the change in the total number of shares of all CEMEX Common
Stock, without regard to classes), and, conversely, in case all or any portion
of the outstanding CEMEX Common Stock shall be combined into a smaller number of
shares of CEMEX Common Stock, the Number of CPOs in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be proportionately reduced (based on the change in the total
number of shares of all CEMEX Common Stock, without regard to classes), such
increase or reduction, as the case may be, to become effective immediately after
the opening of business on the day following the day upon which such subdivision
or combination becomes effective.

(d)  Subject to the last sentence of this paragraph (d), in case
CEMEX shall, by dividend or otherwise, distribute to holders of all or any
portion of the CEMEX Common Stock evidences of CEMEX's indebtedness, shares of
any class of capital stock, securities, cash or property (excluding any rights,
warrants or options referred to in paragraph (b) of this Article I(5), any
dividend or distribution paid exclusively in cash and any dividend or
distribution referred to in paragraph (a) of this Article I(5)), the Number of
CPOs shall be increased so that the same shall equal the number determined by
multiplying the Number of CPOs in effect immediately prior to the effectiveness
of the increase in the Number of CPOs contemplated by this paragraph (d) by a
fraction of which the denominator shall be the current market capitalization
(determined as provided in paragraph (g) of this Article I(5)) of the CEMEX
Common Stock on the date fixed for such distribution less the fair market value
(as determined in good faith by the board of directors of CEMEX, whose
determination shall be conclusive and shall, in the case of securities being
distributed for which prior thereto there is an actual or when issued trading
market, be no less than the value determined by reference to the average of the
closing prices in such market over the period specified in the succeeding
sentence), on the date of such effectiveness, of the evidences of indebtedness,
shares of capital stock, securities, cash and other property so distributed and
the numerator shall be such current market capitalization, such increase to
become effective immediately prior to the opening of

483744.01-New York S4A                  6

business on the day following the date fixed for the payment of such
distribution (such date being referred to as the "Reference Date"). If the board
of directors of CEMEX determines the fair market value of any distribution for
purposes of this paragraph (d) by reference to the actual or when issued trading
market for any securities comprising such distribution, it must in doing so
consider the prices in such market over the same period used in computing the
current market capitalization pursuant to paragraph (g) of this Article I(5).
For purposes of this paragraph (d), any dividend or distribution that includes
shares of CEMEX Common Stock or rights, warrants or options to subscribe for or
purchase shares of CEMEX Common Stock shall be deemed instead to be (A) a
dividend or distribution of the evidences of indebtedness, cash, shares of
capital stock, other securities or other property other than such shares of
CEMEX Common Stock or such rights, warrants or options (making any increase in
the Number of CPOs required by this paragraph (d)) immediately followed by (B) a
dividend or distribution of such shares of CEMEX Common Stock or such rights,
warrants or options (making any further increase in the Number of CPOs required
by paragraph (a) or (b) of this Article I(5), except (A) the Reference Date of
such dividend or distribution as defined in this paragraph (d) shall be
substituted as "the date fixed for the determination of stockholders entitled to
receive such rights, warrants or options" and "the date fixed for such
determination" within the meaning of paragraphs (a) and (b) of this Article I(5)
and (B) any shares of CEMEX Common Stock included in such dividend or
distribution shall not be deemed "outstanding at the close of business on the
date fixed for such determination" within the meaning of paragraph (a) of this
Article I(5)).

(e)  In case CEMEX shall, by dividend or otherwise, make a
distribution to holders of all or any portion of the CEMEX Common Stock
exclusively in cash in an aggregate amount that, together with (A) the aggregate
amount of any other distributions to holders of all or any portion of the CEMEX
Common Stock made exclusively in cash within the 12 months preceding the date of
payment of such distribution and in respect of which no adjustment in the Number
of CPOs pursuant to this paragraph (e) has been made and (B) the aggregate of
any cash plus the fair market value (as determined in good faith by the board of
directors of CEMEX, whose determination shall be conclusive), as of the
expiration of the tender or exchange offer referred to below, of consideration
payable in respect of any tender or exchange offer by CEMEX or a subsidiary of
CEMEX for all or any portion of the CEMEX Common Stock concluded within the 12
months preceding the date of payment of such distribution and in respect of
which no adjustment in the Number of CPOs pursuant to paragraph (f) of this
Article I(5) has been made, exceeds 12.5% of the current market capitalization
of the CEMEX Common Stock (determined as provided in paragraph (g) of this
Article I(5)) on the date fixed for the determination

483744.01-New York S4A                  7

of stockholders entitled to receive such distribution, the Number of CPOs shall
be increased so that the same shall equal the number determined by multiplying
the Number of CPOs in effect immediately prior to the effectiveness of the
number increase contemplated by this paragraph (e) by a fraction of which the
denominator shall be the current market capitalization of the CEMEX Common Stock
(determined as provided in paragraph (g) of this Article I(5)) on the date fixed
for such distribution less the amount of cash distributed in such distribution
and the numerator shall be such current market capitalization, such increase to
become effective immediately prior to the opening of business on the day
following the date fixed for the payment of such distribution.

(f)  In case a tender or exchange offer made by CEMEX or any
subsidiary of CEMEX for all or any portion of the CEMEX Common Stock shall
expire and such tender or exchange offer shall involve an aggregate
consideration having a fair market value (as determined in good faith by the
board of directors of CEMEX, whose determination shall be conclusive) at the
last time (the "Expiration Time") tenders or exchanges may be made pursuant to
such tender or exchange offer (as it may be amended) that, together with (A) the
aggregate of the cash plus the fair market value (as determined in good faith by
the board of directors of CEMEX, whose determination shall be conclusive), as of
the expiration of the other tender or exchange offer referred to below, of
consideration payable in respect of any other tender or exchange offer by CEMEX
or a subsidiary of CEMEX for all or any portion of the CEMEX Common Stock
concluded within the 12 months preceding the Expiration Time and in respect of
which no adjustment to the Number of CPOs pursuant to this paragraph (f) has
been made and (B) the aggregate amount of any distributions to all holders of
the CEMEX Common Stock made exclusively in cash within the 12 months preceding
the Expiration Time and in respect of which no adjustment to the Number of CPOs
pursuant to paragraph (e) of this Article I(5) has been made, exceeds 12.5% of
the current market capitalization of the CEMEX Common Stock (determined as
provided in paragraph (g) of this Article I(5)) at the Expiration Time
(calculated by treating as outstanding any shares tendered for sale or
exchange), the Number of CPOs shall be increased so that the same shall equal
the number determined by multiplying the Number of CPOs in effect immediately
prior to the Expiration Time by a fraction of which the denominator shall be (i)
the current market capitalization of the CEMEX Common Stock (determined as
provided in paragraph (g) of this Article I(5)) at the Expiration Time
(calculated by treating as outstanding any shares tendered for sale or exchange)
minus (ii) the fair market value (determined as aforesaid) of the aggregate
consideration payable to stockholders pursuant to such tender or exchange offer
based on the acceptance (up to any maximum specified in the terms of the tender
or exchange offer) of all shares validly

483744.01-New York S4A                  8

tendered for sale or exchange and not withdrawn as of the Expiration Time (the
shares deemed so accepted, up to any such maximum, being referred to as the
"Purchased Shares") and the numerator shall be such current market
capitalization at the Expiration Time (calculated by reducing the relevant
number of outstanding shares by the number of Purchased Shares), such increase
to become effective immediately prior to the opening of business on the day
following the Expiration Time.

(g)  For the purpose of any computation under this paragraph and
paragraphs (b), (d) and (e) of this Article I(5), the current market price per
share of any class of CEMEX Common Stock on any date in question shall be deemed
to be the average of the daily Closing Prices (as defined herein) for such class
for the five consecutive Trading Days (as defined herein) selected by CEMEX
commencing not more than 20 Trading Days before, and ending not later than, the
date in question; provided, however, that (A) if the "ex" date (as hereinafter
defined) for any event (other than the issuance or distribution requiring such
computation) that requires an adjustment to the Number of CPOs pursuant to
paragraph (a), (b), (c), (d), (e) or (f) above ("Other Event") occurs on or
after the 20th Trading Day prior to the date in question and prior to the "ex"
date for the issuance or distribution requiring such computation (the "Current
Event"), the Closing Price for such class for each Trading Day prior to the "ex"
date for such Other Event shall be adjusted by multiplying such Closing Price by
the reciprocal fraction by which the Number of CPOs is so required to be
adjusted as a result of such Other Event, (B) if the "ex" date for any Other
Event occurs after the "ex" date for the Current Event and on or prior to the
date in question, the Closing Price for such class for each Trading Day on and
after the "ex" date for such Other Event shall be adjusted by multiplying such
Closing Price by the same fraction by which the Number of CPOs is so required to
be adjusted as a result of such Other Event, (C) if the "ex" date for any Other
Event occurs on the "ex" date for the Current Event, one of those events shall
be deemed for purposes of clauses (A) and (B) of this proviso to have an "ex"
date occurring prior to the "ex" date for the other event, and (D) if the "ex"
date for the Current Event is on or prior to the date in question, after taking
into account any adjustment required pursuant to clause (B) of this proviso, the
Closing Price for such class for each Trading Day on or after such "ex" date
shall be adjusted by adding thereto an amount calculated by dividing (1) the
amount of any cash plus the fair market value on the date in question (as
determined in good faith by the board of directors of CEMEX (in a manner
consistent with any determination of such value for purposes of paragraph (d) or
(e) of this Article I(5)), whose determination shall be conclusive) of the
rights, warrants, options, evidences of indebtedness, shares of capital stock,
securities or other property being distributed by (2) the number of all shares
of CEMEX Common Stock

483744.01-New York S4A                  9

outstanding as of the close of business on the day before such "ex" date. For
the purpose of any computation under paragraph (f) of this Article I(5), the
current market price per share of any class of CEMEX Common Stock on any date in
question shall be deemed to be the average of the daily Closing Prices for the 5
consecutive Trading Days selected by CEMEX commencing on or after the latest
(the "Commencement Date") of (A) the date 20 Trading Days before the date in
question, (B) the date of commencement of the tender or exchange offer requiring
such computation and (C) the date of the last amendment, if any, of such tender
or exchange offer involving a change in the maximum number of shares for which
tenders are sought or a change in the consideration offered, and ending not
later than the date of the Expiration Time of such tender or exchange offer
(which shall occur on a day no earlier than the last of the 5 consecutive
trading days beginning on the Commencement Date); provided, however, that if the
"ex" date for any Other Event (other than the tender or exchange offer requiring
such computation) occurs on or after the Commencement Date and on or prior to
the date of the Expiration Time for the tender or exchange offer requiring such
computation, the Closing Price for such class for each Trading Day prior to the
"ex" date for such Other Event shall be adjusted by multiplying such Closing
Price by the reciprocal fraction by which the Number of CPOs is so required to
be adjusted as a result of such other event. For the purpose of any computation
under paragraph (d), (e) or (f) of this Article I(5), the current market
capitalization of the CEMEX Common Stock on any day shall be deemed to be the
sum of the market values for each class of CEMEX Common Stock on such day. For
each such class, the market value on any day shall be deemed to equal the
current market price per share for such class on such day, multiplied by the
number of shares of such class outstanding on such day; provided that, in
determining such number of outstanding shares on such day, no effect shall be
given to any change in the number of such shares outstanding attributable to any
event for which an adjustment was made to any Closing Price used to determine
such current market price pursuant to clause (B) or (D) of the proviso to the
second preceding sentence and provided, further, that the same 5 Trading Days
shall be used to calculate the current market price for each class of CEMEX
Common Stock. Similarly, in determining the number of shares of all CEMEX Common
Stock outstanding on the relevant date for the purpose of calculating any
adjustment in the Number of CPOs pursuant to paragraph (b) of this Article I(5),
no effect shall be given to any change in the number of such shares outstanding
attributable to any event for which adjustment was made pursuant to such clause
(B) or (D) to any Closing Price used to determine the current market price of an
affected class for the purpose of calculating such adjustment. For purposes of
this paragraph, the term "ex" date, (A) when used with respect to any issuance
or distribution, means, with respect to any class of CEMEX Common Stock, the
first date on which such class trades regular way on the relevant

483744.01-New York S4A                 10

exchange or in the relevant market from which the Closing Price was obtained
without the right to receive such issuance or distribution, (B) when used with
respect to any subdivision or combination of shares of CEMEX Common Stock, means
the first date on which such class trades regular way on such exchange or in
such market after the time at which such subdivision or combination becomes
effective, and (C) when used with respect to any tender or exchange offer means
the first date on which such class trades regular way on such exchange or in
such market after the Expiration Time of such tender or exchange offer.

"Closing Price" means (i) in respect of any class of Common Stock, for
any Trading Day, the last reported sale price, regular way, of such Common Stock
or, in case no such reported sale takes place on such Trading Day, the average
of the reported closing bid and asked prices, regular way, of such Common Stock
on the Mexican Stock Exchange (the Bolsa Mexicana de Valores, S.A. de C.V.) or,
if such Common Stock is not listed or admitted for trading on such exchange, the
average of the reported closing bid and asked prices of such Common Stock as
furnished by any three leading Mexican Stock Exchange member firms selected from
time to time by CEMEX for that purpose and (ii) in respect of any class of CPOs
representing Common Stock for any Trading Day, the last reported sale price,
regular way, of or, in case no such reported sale takes place on such Trading
Day, the average of the reported closing bid and asked prices, regular way, for
such CPOs, on the Mexican Stock Exchange or, if such CPOs are not listed or
admitted for trading on such exchange, the average of the reported closing bid
and asked prices of such CPOs as furnished by any three leading Mexican Stock
Exchange member firms selected from time to time by CEMEX for that purpose.

"Trading Day" means each Monday, Tuesday, Wednesday, Thursday and
Friday, other than any day on which the Mexican Stock Exchange is not open for
trading.

(h)  (i)   In case CEMEX shall issue or sell any shares of any
class of CEMEX Common Stock without consideration or at a price per share less
than 90% of the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date of such issuance
or sale, the Number of CPOs in effect at the opening of business on the day
following the date of such issuance or sale shall be increased by:

(A)  multiplying the Number of CPOs in effect at the close
of business on the day immediately preceding the date of
such issuance or sale by

483744.01-New York S4A                 11

(B)  a fraction, of which

(1)  the numerator shall be the number of shares of
CEMEX Common Stock outstanding at the close of
business on the date immediately preceding such
issuance or sale, plus the number of shares of
CEMEX Common Stock so issued or sold, and

(2)  the denominator shall be the number of shares of
CEMEX Common Stock outstanding at the close of
business on the date immediately preceding such
issuance or sale, plus the number of shares of
CEMEX Common Stock which the aggregate
consideration, if any, received (or to be
received) by CEMEX for the total number of such
additional shares of CEMEX Common Stock so issued
or sold would purchase at such current market
price per share.

(ii)  For the purposes of this Article I(5)(h), the issuance
of any warrants, options, subscriptions, or purchase rights with respect to
shares of any class of CEMEX Common Stock and the issuance of any
securities convertible into or exchangeable for shares of any class of
CEMEX Common Stock (or the issuance of any warrants, options or any rights
with respect to such convertible or exchangeable securities) shall be
deemed an issuance of such shares of such class of CEMEX Common Stock at
such time if the Net Consideration Per Share (as hereinafter determined)
which may be received by CEMEX for such CEMEX Common Stock shall be less
than 90% of the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date of such
issuance. Any obligation, agreement, or undertaking to issue warrants,
options, subscriptions, or purchase rights at any time in the future shall
be deemed to be an issuance at the time such obligation, agreement or
undertaking is made or arises.

483744.01-New York S4A                 12

(iii) No adjustment to the Number of CPOs shall be made
under this Article I(5)(h) upon the sale or issuance (or deemed issuance)
of any shares of CEMEX Common Stock pursuant to:

(A)  the exercise of any warrants, options,
subscriptions, or purchase rights or the exercise of
any conversion or exchange rights in any convertible
securities, in each case, outstanding as of the close
of business on the date hereof;

(B)  any employee stock option, purchase or incentive
plan, whether or not existing on the date hereof;

(C)  any of the events referred to in paragraphs (a),
(b), (c), (d), (e) and (f) of this Article I(5);

(D)  anti-dilution provisions contained in any of the
securities referred to in the preceding clauses (A),
(B) and (C) hereof; or

(E)  if any adjustment shall previously have been made,
or deemed not required hereunder, upon the issuance of
any such warrants, options, or subscription or purchase
rights or upon the issuance of any convertible
securities (or upon the issuance of any warrants,
options or any rights therefor) as above provided.

(iv)  If the Net Consideration Per Share of any such
warrants, options, subscriptions, or purchase rights or convertible
securities is decreased from time to time, then, upon the effectiveness of
each such decrease, the Number of CPOs shall be adjusted to such Number of
CPOs as would have obtained (A) had the adjustments made upon the issuance
of such warrants, options, rights, or convertible securities been made upon
the basis of the decreased Net Consideration Per Share of such securities,
and (B) had adjustments made to the Number of CPOs since the date of
issuance of such securities been made to the Number of CPOs as adjusted
pursuant to clause (A) above. Any adjustment of the Number of CPOs with
respect to this paragraph which relates to warrants, options,
subscriptions, purchase rights or

483744.01-New York S4A                 13

convertible securities with respect to shares of CEMEX Common Stock shall
be disregarded if, as, when and to the extent such warrants, options,
subscriptions, purchase rights or convertible securities expire or are
canceled without being exercised or converted, so that the Number of CPOs
effective immediately upon such cancellation or expiration shall be the
same as the Number of CPOs in effect at the time of the issuance of the
expired or canceled warrants, options, subscriptions, purchase rights, or
convertible securities with such additional adjustments as would have been
made to that Number of CPOs had the expired or canceled warrants, options,
subscriptions, purchase rights or convertible securities not been issued.

(v)   "Net Consideration Per Share" shall mean the total
amount of consideration, if any, received by CEMEX as of the date of
issuance in respect to the issuance of such warrants, options,
subscriptions, or other purchase rights or convertible or exchangeable
securities, plus the minimum amount of consideration, if any, payable to
CEMEX upon exercise or conversion thereof, divided by the aggregate number
of shares of CEMEX Common Stock that would be issued if all such warrants,
options, subscriptions, or other purchase rights or convertible or
exchangeable securities were exercised, exchanged, or converted, without
giving effect to any possible future upward price adjustments or rate
adjustments.

(vi)  If part or all of the consideration received by CEMEX
in respect to the issuance of CEMEX Common Stock or of any of the
securities described in this Article I(5)(h) consists of property other
than cash, such consideration shall be deemed to have a fair market value
reasonably determined in good faith by the board of directors of CEMEX.

(i)  No adjustment in the Number of CPOs shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Number of CPOs; provided, however, that any adjustments which by reason of this
paragraph (i) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment.

(j)  In addition to the adjustments in the Number of CPOs
required by paragraphs (a), (b), (c), (d), (e), (f) and (h) of this Article
I(5), CEMEX may from time to time in its discretion make such increases in the
Number of CPOs as it considers to be advisable in order to avoid or diminish any
Mexican income tax to any holders of shares of CEMEX Common Stock resulting from
any dividend or distribution of stock or issuance of rights or warrants to
purchase or subscribe for

483744.01-New York S4A                 14

stock or from any event treated as such for income tax purposes or for any other
reasons.

(k)  For purposes of calculating the number of shares of CEMEX
Common Stock at any time outstanding or the number of shares of CEMEX Common
Stock acquired in any tender or exchange offer, the number of shares of CEMEX
held in its treasury shall not be included.

(l)  CEMEX shall ensure that the time for determining the
stockholders entitled to receive any dividend, issuance or other distribution in
respect of any CEMEX Common Stock, the time of effectiveness of any subdivision
or combination of any CEMEX Common Stock and the expiration time of any tender
or exchange offer made by CEMEX or any subsidiary of CEMEX for any CEMEX Common
Stock shall be at or after the close of business on the date fixed for
determining such stockholders, or on the date of such effectiveness or
expiration, as the case may be, so that (whether or not any adjustment to the
Number of CPOs is required pursuant to this Article I(5)) any Subsequent Closing
Date occurring on such date shall be deemed to have occurred prior to such
relevant time on such date.

(m)  Whenever the Number of CPOs is adjusted as herein provided,
CEMEX shall promptly deliver to the Seller a notice setting forth the adjusted
Number of CPOs and showing in reasonable detail the facts upon which such
adjustment is based.

(n)  In the event that CEMEX shall be a party to any transaction
(including any (i) recapitalization or reclassification of all or any portion of
the CEMEX Common Stock (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination of all or any portion of the CEMEX Common Stock), (ii)
consolidation of CEMEX with, or merger of CEMEX into, any other person, or any
merger of another person into CEMEX (other than a merger which does not result
in a reclassification, conversion, exchange or cancellation of any outstanding
CEMEX Common Stock), (iii) conveyance, transfer, sale or lease of all or
substantially all of the assets of CEMEX, or (iv) compulsory share exchange)
pursuant to which the CPOs are converted into the right to receive other
securities, cash or other property, then lawful provision shall be made as part
of the terms of such transaction providing that the Seller shall have the right
thereafter, to purchase the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, reclassification,
conveyance, transfer or sale by a holder of the Number of CPOs which the Seller
was entitled to purchase immediately prior to such consolidation,

483744.01-New York S4A                 15

merger, reclassification, conveyance, transfer or sale (the "Transaction
Consideration"), assuming the Seller is not a Person with which CEMEX
consolidated or into which CEMEX merged or which merged into CEMEX, or to which
such sale or transfer was made, as the case may be (a "Constituent Person"), or
an Affiliate of a Constituent Person, and failed to exercise his right of
election, if any, as to the kind or amount of securities, cash or other property
receivable upon such consolidation, merger, reclassification, conveyance,
transfer or sale (provided that if the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer is
not the same for each CPO in respect of which such rights of election shall not
have been exercised ("non-electing share"), then for the purpose of this Article
I(5) the kind and amount of securities, cash and other property receivable upon
such consolidation, merger, sale or transfer by each non-electing share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
non-electing shares).

CEMEX or the person formed by such consolidation or resulting from
such merger or which acquired such assets or CEMEX's shares, as the case may be,
shall execute and deliver to the Seller a notice setting forth the Seller's
rights as provided above. Such notice shall provide for adjustments which, for
events subsequent to the effective date of such notice, shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
I(5). The above provisions of this Article I(5) shall similarly apply to
successive transactions of the foregoing type.

ARTICLE II

----------------------------------------

The Seller hereby represents and warrants to CEMEX as follows:

1.   Corporate Organization. The Seller is a corporation duly
organized, validly existing and in good standing under the laws of Singapore and
has all necessary power and authority to carry on its business as it is now
being conducted and to own the properties and assets it now owns and is
qualified or licensed to do business as a foreign corporation in every
jurisdiction in which it is required to so qualify and in which the failure to

operations or financial condition (a "Material Adverse Effect") of the Seller
and its subsidiaries taken as a whole.

483744.01-New York S4A                 16

2.   Authorization. The Seller has all necessary power and authority
to enter into the Transaction Documents and to carry out the transactions on its
part contemplated thereby. The Seller has taken all actions required by law, its
charter documents or otherwise to be taken by it to authorize the execution and
delivery of the Transaction Documents and the consummation of the transactions
on its part contemplated thereby. Each of the Transaction Documents and any
other instrument to be executed and delivered by the Seller at the Closing or on
any Subsequent Closing Date is, or will be when executed and delivered, the
valid and binding agreement of the Seller enforceable against it in accordance
with its terms, except to the extent that (i) such validity, binding effect or
enforceability may be subject to bankruptcy, insolvency, reorganization,
moratorium or other similar laws now or hereafter in effect relating to
creditors' rights generally, and (ii) the remedy of specific performance and
injunctive and other forms of equitable relief sought may be subject to
equitable defenses and to the discretion of the court before which any
proceeding therefor may be brought.

3.   No Violation. Neither the execution and delivery of the
Transaction Documents by the Seller nor the consummation by the Seller of the
transactions contemplated thereby, including, without limitation, any short
sales and hedging transactions to be effected by the Seller, will (i) violate
any provision of the organizational documents of the Seller, or (ii) violate,
conflict with, or constitute a default (or an event which, with notice or lapse
of time or both, would constitute a default) under, or result in the termination
of, or permit a third party to terminate the rights of the Seller under, or
accelerate the performance required by, or create or accelerate any rights to
repurchase, rights of first offer or rights of first refusal under, or cause the
acceleration of the maturity of any debt or obligation pursuant to, or result in
the creation or imposition of any security interest, lien or other encumbrance
upon any property of the Seller under any agreement or commitment to which it is
a party, or (iii) violate any statute or law or any judgment, decree, order,
regulation or rule of any court or governmental authority, except in the case of
each of clauses (i), (ii) and (iii) where such violations, conflicts, defaults,
terminations or accelerations individually or in the aggregate would not (x)
have a Material Adverse Effect on the Seller and its subsidiaries taken as a
whole or (y) adversely affect the Seller's ability to perform its obligations
hereunder.

4.   Ownership of Seller's Shares. The Seller is the record and
beneficial owner of all of the Seller's Shares, except to the extent a portion
of the Seller's Shares (i) is held by the Trustee under the Investor Trust
Agreement or (ii) has been transferred pursuant to the terms hereof. On the
Closing Date, the Seller will own the Seller's Shares free and clear of all
liens and encumbrances that would

the Seller's Shares have not been registered under the securities laws of any
jurisdiction and are being offered and sold in reliance upon exemptions provided

and, therefore, cannot be resold or transferred unless they are subsequently
registered under applicable securities laws or unless an exemption from such
registration is available; (c) no regulatory authority has made any finding or
determination as to the fairness for investment of the Seller's Shares and no
regulatory authority has recommended or endorsed or will recommend or endorse
any such offer or sale; (d) that it is acquiring the Seller's Shares for
investment purposes only for its own account and not with any view toward a
distribution thereof; (e) that it has no contract, undertaking, agreement or
arrangement with any person to sell, transfer or pledge to such person or anyone

8. Brokers' Fees. CEMEX has no liability or obligation to pay any fees
or commissions to any broker, finder, or agent with respect to the sale of the

9.   Financial Statements and Disclosures.

(a)  The consolidated historical financial statements of CEMEX
and its consolidated subsidiaries, and the related notes thereto, included in
CEMEX's Annual Report on Form 20-F for the fiscal year ended December 31, 2001
(the "2001 Form 20-F"), as filed by CEMEX with the U.S. Securities and Exchange
Commission (the "SEC"), present fairly in all material respects the consolidated
financial position of CEMEX and its consolidated subsidiaries taken together as
a whole as of the dates indicated and the results of their operations and the
changes in their consolidated cash flows for the periods specified; and said
financial statements have been prepared in conformity with Mexican generally
accepted accounting principles applied on a consistent basis throughout the
periods involved (except as otherwise noted therein).

(b)  As of the date of this Agreement, (i) there has been no
change in the consolidated assets, liabilities or financial condition of CEMEX
from that reflected in the 2001 Form 20-F, except for changes in the ordinary
course of business none of which have, singly or in the aggregate, had a
Material Adverse Effect on CEMEX and its subsidiaries taken as a whole, (ii)
other than general economic or political conditions, since the filing of the
2001 Form 20-F, there has been no event causing a Material Adverse Effect as to
CEMEX and its subsidiaries taken as a whole, nor any development that could,
singly or in the aggregate, reasonably be expected to result in a Material
Adverse Effect as to CEMEX and its subsidiaries taken as a whole, and (iii) the
aggregate number of shares of CEMEX Common Stock issued or issuable pursuant to
the exercise of all warrants, options, subscriptions, purchase rights or
conversion or exchange rights in any convertible securities does not materially
exceed the aggregate number of such shares issued or so issuable as reflected in
the consolidated financial statements of CEMEX included in the 2001 Form 20-F,
except, in the case of clauses (i), (ii) and (iii), as disclosed to the Seller
in writing or otherwise publicly disclosed by CEMEX.

(3)  The 2001 Form 20-F did not, at the time of its filing with
the SEC, contain an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the

483744.01-New York S4A                  22

circumstances under which they were made when the 2001 Form 20-F was so filed,
not misleading.

10.  Contemporaneous Agreements. Contemporaneously with entering into
this Agreement, CEMEX is entering into separate Stock Purchase Agreements
substantively identical to this Agreement (other than in respect to Article
IV(7) and (11) hereof) with each of AIG Asian Infrastructure Fund II LP, Pan
Asian Cement Investors, L.P., and GIMV N.V., who together with the Seller and
Orchid Asia II, L.P. constitute, as of the date hereof, all of the stockholders
of CAH that have elected to sell all or any portion of their shares of common
stock of CAH to CEMEX.

11.  No Liquidation of CAH. Until the later of January 2, 2004 or the
date that no further Seller's Shares remain subject to this agreement, CEMEX
shall not effect or permit any liquidation, merger, consolidation or other
organic change in the organization of CAH.

Period                        That May Be Hedged
---------------------------------------   ---------------------------

; provided, further, that any such Hedging activities must be conducted in such
a manner as to not require registration under the securities laws of any
jurisdiction (including, without limitation, the United States of America). It
being understood that the Seller may not Hedge more than 40% of the CPOs
remaining to be acquired by it hereunder at any time (which limitation is
exclusive of any CPOs the Seller may have already acquired hereunder).

4.   Dividends on Seller's Shares. All dividends on the Seller's
Shares will be paid by the Seller to CEMEX upon receipt by the Seller. Seller
hereby instructs the paying agent for CAH to pay any such dividends directly to
CEMEX at:

Notwithstanding the foregoing, the Seller may retain such portion of any

withholding expense borne by the Seller and arising from such dividend.

5.   Dividends on CPOs. To the extent that CEMEX makes a dividend or
other distribution in CEMEX Common Stock on the CPOs to be received by the
Seller hereunder, such that the aggregate value (as determined in good faith by
the board of directors of CEMEX (in a manner consistent with any determination
of such value for purposes of Article I(5)) of all dividends or other
distributions made exclusively in CEMEX Common Stock on such CPOs within the 12
months

483744.01-New York S4A                 24

preceding the date of payment of such dividend or distribution (and including
the value of such distribution), and in respect of which no adjustment in the
Number of CPOs pursuant to Article I(5) has been made, exceeds 5% of the
aggregate weighted average price of such CPOs on the Mexican Stock Exchange on
the date such dividend or distribution is declared, then the amount of CEMEX
Common Stock by which such dividends or distributions exceed 5% shall be for the
benefit of the Seller.

6.   Escrow of Seller's Shares. The Seller and CEMEX will execute and
deliver the Escrow Agreement at Closing.

7.   Amended Shareholders Agreement and Charter. CEMEX and the Seller
each will (and to the extent required, CEMEX will cause Cemex Manila Investments
B.V. and CEMEX's other Affiliates that own shares of CAH to) (i) take all
legally permissible action to cause the director(s) it has appointed to the
Board of Directors of CAH (A) to approve the Amended Shareholders Agreement and
cause CAH to ratify the Amended Shareholders Agreement and agree to be bound
thereby, and (B) to approve the Amended and Restated Charter, (ii) approve and
execute the Amended Shareholders Agreement, and (iii) approve the Amended and
Restated Charter. CEMEX will cause CAH to lodge the Amended and Restated Charter
with the Registrar prior to the first Subsequent Closing Date.

8.   Notice of Developments. Each Party will give prompt written
notice to the other of any material adverse development causing a breach of any
of its own representations, warranties, covenants or agreements contained herein
or in the Escrow Agreement.

9.   General. After the Closing, each of the Parties shall, from time
to time, at the request of the other Party and without further cost or expense
to the Party making the request, execute and deliver (and, if appropriate, file)
or cause to be executed and delivered (and, if appropriate, filed) such other
instruments of conveyance and transfer and other documents reasonably required
to carry out the intent of the Transaction Documents as any other Party may
reasonably request and continue to use reasonable efforts to obtain any
consents, approvals, authorizations and waivers necessary in order to more
effectively consummate the transactions contemplated herein and therein.

10.  Confidentiality. The Seller will treat and hold as such all
Confidential Information (as defined below), refrain from using any Confidential
Information except in connection with this Agreement, and deliver promptly to
CEMEX or destroy, at the request and option of CEMEX, all tangible embodiments

483744.01-New York S4A                 25

(and all copies) of Confidential Information that are in its possession;
provided, however, that Seller may share such Confidential Information on an as
needed basis with its officers, Affiliates, limited partners and legal and
financial advisers if such officers, Affiliates, limited partners and advisers
are instructed by the Seller to treat and hold as such all Confidential
Information. If the Seller is required under law, regulation or legal process to
disclose any Confidential Information, the Seller may disclose such Confidential
Information as is so required to be disclosed. In the event that the Seller is
requested or required to disclose any Confidential Information, the Seller will
notify CEMEX promptly of the request or requirement. For purposes hereof,
"Confidential Information" means any information received from CEMEX, CAH or any
of their respective representatives or Affiliates concerning the businesses and
affairs of CAH that is not already generally available to the public. In any
event, the aforesaid confidential obligations do not apply to any Confidential
Information that is in the public domain other than as a result of the Seller's
breach of undertaking herein, or in relation to any Confidential Information
that has been given to the Seller by a third party who is not known to the
Seller to be in breach of any obligation of secrecy to CEMEX or to any
Confidential Information already in Seller's free possession at the time of
disclosure by CEMEX, CAH or any of their respective Affiliates.

11.  Ownership of Seller's Shares; Resignation of Director. For the
avoidance of doubt, CEMEX and the Seller acknowledge and agree that pursuant to
Section 4.1(a) of the Amended Shareholders Agreement, notwithstanding the
delivery of the Seller's Shares to the Escrow Agent as contemplated by the
Transaction Documents, the Seller shall be deemed to "own" the Seller's Shares
held by the Escrow Agent for purposes of Section 4.1(a) of the Amended
Shareholders Agreement; provided, that the Seller shall not be deemed to "own"
any Seller's Shares transferred to CEMEX (or its nominee or designee) on a
Subsequent Closing Date. The Seller agrees to cause the director it has
appointed to the Board of Directors of CAH to resign effective as of 5:00 pm New
York City time on the Closing Date and to waive its right to appoint such
director until the earlier of (i) such time as it is no longer entitled to elect
a director to the Board of Directors of CAH under Section 4.1(a) of the Amended
Shareholders Agreement or (ii) the termination of this Agreement.

12.  Subsequent Modification. If at any time or from time to time
after the date hereof and prior to the final Subsequent Closing Date, CEMEX or
any of its Affiliates shall have entered into an agreement or understanding
relating to the acquisition of or other payment in respect to (whether for cash
or other consideration, and whether pursuant to any form of option, call, put,
purchase, redemption,

483744.01-New York S4A                 26

exchange, retirement or other right) shares of common stock of CAH from a
stockholder other than the Seller, and the terms of such other agreement or
understanding are more favorable to such stockholder than the terms hereof or
the Escrow Agreement are to the Seller, then, within thirty (30) days of the
date of such other agreement or understanding, CEMEX shall provide to Seller a
written description of such other agreement or understanding and provide Seller
a period of at least thirty (30) days in which to decide whether or not to
modify the terms hereof or of the Escrow Agreement to reflect the terms of such
other agreement or understanding (including, without limitation, a change in the
amounts used to calculate the Number of CPOs in Article I(2) hereof).

13.  No Other Transfer of Seller's Shares.

(a)  CEMEX hereby consents to the transfer and release of all of
the Seller's Shares held of record by the Trustee under the Investor Trust
Agreement for purposes of the transactions contemplated in this Agreement;
provided, however, that if the sale of all the Seller's Shares to CEMEX
contemplated hereby is not consummated, then the Seller shall promptly redeposit
50% of such unsold Seller's Shares with the Trustee under the Investor Trust
Agreement.

(b)  The Seller agrees that, except as expressly permitted by
this Agreement or the Transaction Documents, it will not (i) sell, assign (by
operation of law or otherwise) or otherwise dispose of, or grant any option with
respect to, any of the Seller's Shares, or (ii) create or suffer to exist any
lien, security interest, option or other charge or encumbrance upon or with
respect to any of the Seller's Shares.

of this Agreement and the Escrow Agreement, on March 31, 2004, June 30,
2004, September 30, 2004 and December 31, 2004 (or if any such day is not a

to be sold on a Subsequent Closing Date being referred to herein as the
"Number of Shares").

(b)  Notwithstanding anything to the contrary contained in the
foregoing Article 1(1 )(a), as to the Number of Shares required to be
purchased by CEMEX on June 30,2004, September 30,2004 or December 31, 2004,
at any time until:

sjdc-1278732.4

(i)   June 15, 2003 (or if such day is not a Business Day,
then on the next succeeding Business Day), in respect to the Number of
Shares required to be purchased by CEMEX on June 30, 2004;

(ii)  September 15, 2003 (or if such day is not a Business
Day, then on the next succeeding Business Day), in respect to the Number of
Shares required to be purchased by CEMEX on September 30, 2004; and

(iii) December 15, 2003 (or if such day is not a Business

Shares required to be purchased by CEMEX on December 31,2004;

CEMEX may designate any Business Day prior to the applicable Subsequent
Closing Date as the "Early Subsequent Closing Date" for such Number of
Shares to be purchased. Following any such designation, such Early
Subsequent Closing Date shall when used with respect to the corresponding
Number of CPOs, be deemed to be the Subsequent Closing Date for all
purposes under the Transaction Documents, and references to such Subsequent
Closing Date shall be deemed to be references to such Early Subsequent
Closing Date.

(c)  If at any time or from time to time after the date hereof
and prior to the final Subsequent Closing Date, CEMEX designates an Early
Subsequent Closing Date in respect to the Seller's Shares in accordance
with the foregoing, or in respect to the shares of CAH to be acquired by
CEMEX in accordance with those separate Stock Purchase Agreements referred
to in the first sentence of Section 6 of this Amendment No. 2, CEMEX shall
contemporaneously designate the same Early Subsequent Closing Date for such
other holders of CAH shares and the Seller, as applicable."

Base Amount shall accrue at a rate (the "Base Deferral Fee Rate") equal to

(b)  Payment of Base Deferral Fee. CEMEX promises to pay to the
Seller, in arrears, the Base Deferral Fee and other amounts due hereunder on
each Payment Date.

(c)  Default Fee. If CEMEX fails to pay any amount when due hereunder,
whether of the Base Deferral Fee or otherwise, and whether due to acceleration
or otherwise, CEMEX shall pay to the Seller a fee (the "Default Fee") on such
amount for each day such past due amount remains unpaid, payable on demand, at
the rate equal to the sum of (i) the Base Deferral Fee Rate, plus (ii) two
percent (2%) per annum.

sjdc-1278732.4

(d)  Taxes.

(i)  All sums payable to the Seller under this Amendment No. 2,

and all offsets, deductions or withholdings for any and all present or
future taxes, levies, imposts, stamp or other duties, fees, assessments,
deductions, withholdings, other governmental charges, and liabilities
(including penalties and interest) with respect thereto imposed by any
governmental authority (collectively, "Taxes"). If CEMEX is prohibited by
law from making any such payments to the Seller hereunder free and clear of
any such offsets, deductions, withholdings and payments, then (A) CEMEX
shall pay the full amount required to be offset, deducted, withheld or paid
to the relevant governmental authority in accordance with all applicable
laws and (B) the amount which CEMEX is required to pay to the Seller shall
be increased by such additional amount as may be necessary in order that
the actual amount received by the Seller after such offset, deduction,
withholding or payment of Taxes (including offsets, deductions,
withholdings and payments applicable to additional sums payable to the
Seller under this Section 3(d)) shall equal the full amount intended to be

sjdc-1278732.4
9

(a)  Corporate Organization. Seller is a corporation duly organized,
validly existing and in good standing under the laws of Singapore and has all
necessary power and authority to carry on its business as it is now being
conducted and to own the properties and assets it now owns and is qualified or
licensed to do business as a foreign limited partnership in every jurisdiction
in which it is required to so qualify and in which the failure to so qualify
would have a Material Adverse Effect on the business, results of operations or
financial condition of Seller and its subsidiaries taken as a whole.

(b)  Authorization. The Seller has all necessary power and authority
to enter into the Amendments and to carry out the transactions on its part
contemplated thereby. The Seller has taken all actions required by law, its
charter documents or otherwise to be taken by it to authorize the execution and
delivery of the Amendments and the consummation of the transactions on its part
contemplated thereby. Each of the Amendments and any other instrument to be
executed and delivered by the Seller on the date hereof and at any Subsequent
Closing Date is, or will be when executed and delivered, the valid and binding
agreement of the Seller enforceable against it in accordance with its terms,
except to the extent that (i) such validity, binding effect or enforceability
may be subject to bankruptcy, insolvency, reorganization, moratorium or other
similar laws now or hereafter in effect relating to creditors' rights generally,
and (ii) the remedy of specific performance and injunctive and other forms of
equitable relief sought may be subject to equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought.

(c)  No Violation. Neither the execution and delivery of the
Amendments by the Seller nor the consummation by the Seller of the transactions
contemplated thereby, will (i) violate any provision of the organizational
documents of the Seller, or (ii) violate, conflict with, or constitute a default
(or an event which, with notice or lapse of time or both, would constitute a
default) under, or result in the termination of, or permit a third party to
terminate the rights of the Seller under, or accelerate the performance required
by, or create or accelerate any rights to repurchase, rights of first offer or
rights of first refusal under, or cause the acceleration of the maturity of any
debt or obligation pursuant to, or result in the creation or imposition of any
security interest, lien or other encumbrance upon any property of the Seller
under any agreement or commitment to which it is a party, or (iii) violate any
statute or law or any judgment, decree, order, regulation or rule of any court
or governmental authority, except in the case of each of clauses (i), (ii) and
(iii) where such violations, conflicts, defaults, terminations or accelerations
individually or in the aggregate would not (x) have a Material Adverse Effect on
the Seller and its subsidiaries taken as a whole or (y) adversely affect the
Seller's ability to perform its obligations hereunder.

Section 5.  Representations and Warranties of CEMEX. CEMEX hereby represents
and warrants to the Seller as follows:

(a)  Corporate Organization. CEMEX is a corporation duly organized,
validly existing and in good standing under the laws of Mexico and has all
necessary power and authority to carry on its business as it is now being
conducted and to own the properties and assets it now owns and is qualified or
licensed to do business as a foreign corporation in every

sjdc-1278732.4                         10

jurisdiction in which it is required to so qualify and in which the failure to
so qualify would have a Material Adverse Effect on the business, results of
operations or financial condition of CEMEX and its subsidiaries taken as a
whole.

(b)  Authorization. CEMEX has all necessary power and authority to
enter into the Amendments and to carry out the transactions on its part
contemplated thereby. CEMEX has taken all actions required by law, its charter
documents or otherwise to be taken by it to authorize the execution and delivery
of the Amendments and the consummation of the transactions on its part
contemplated thereby. Each of the Amendments and any other instrument to be
executed and delivered by CEMEX on the date hereof and at any Subsequent Closing
Date is, or will be when executed and delivered, the valid and binding agreement
of CEMEX enforceable against it in accordance with its terms, except to the
extent that (i) such validity, binding effect or enforceability may be subject
to bankruptcy, insolvency, reorganization, moratorium or other similar laws now
or hereafter in effect relating to creditors' rights generally, and (ii) the
remedy of specific performance and injunctive and other forms of equitable
relief sought may be subject to equitable defenses and to the discretion of the
court before which any proceeding therefor may be brought. CEMEX's obligations
hereunder will rank not less than pari passu with all of CEMEX's other unsecured
Debt and obligations.

(c)  No Violation. Neither the execution and delivery of the
Amendments by CEMEX nor the consummation by CEMEX of the transactions
contemplated hereby, including, should CEMEX so elect, the delivery to the
Escrow Agent of the Acquisition Amount and the acquisition and deposit to the
Seller's Depositary Account of the Number of CPOs, will (i) violate any
provision of its charter documents, or (ii) violate, conflict with, or
constitute a default (or an event which, with notice or lapse of time or both,
would constitute a default) under, or result in the termination of, or permit a
third party to terminate its rights under, or accelerate the performance
required by, or create or accelerate any rights to repurchase, rights of first
offer or rights of first refusal under, or cause the acceleration of the
maturity of any debt or obligation pursuant to, or result in the creation or
imposition of any security interest, lien or other encumbrance upon any property
of CEMEX under, any agreement or commitment to which CEMEX is a party, or (iii)
violate any statute or law or any judgment, decree, order, regulation or rule of
any court or governmental authority, except in the case of each of clauses (i),
(ii) and (iii) where such violations, conflicts, defaults, terminations or
accelerations individually or in the aggregate would not (x) have a Material
Adverse Effect on CEMEX and its subsidiaries taken as a whole or (y) adversely
affect CEMEX's ability to perform its obligations hereunder.

(d)  Financial Statements and Disclosures.

(i)   The consolidated historical financial statements of CEMEX
and its consolidated subsidiaries, and the related notes thereto, filed by CEMEX

(the "Financial Statements") present fairly in all material respects the
consolidated financial position of CEMEX and its consolidated subsidiaries taken
together as a whole as of the dates indicated and the results of their
operations and the changes in their consolidated cash flows for the periods
specified; and said Financial Statements have been prepared in

sjdc-1278732.4                         11

conformity with generally accepted accounting principles in Mexico applied on a
consistent basis throughout the periods involved (except as otherwise noted
therein).

(ii)  As of the date of this Amendment No. 2, (A) there has been
no change in the consolidated assets, liabilities or financial condition of
CEMEX from that reflected in the Financial Statements, except for changes in the
ordinary course of business none of which have, singly or in the aggregate, had
a Material Adverse Effect on CEMEX and its subsidiaries taken as a whole, (B)
other than general economic or political conditions, since the filing of the
Financial Statements, there has been no event causing a Material Adverse Effect
as to CEMEX and its subsidiaries taken as a whole, nor any development that
could, singly or in the aggregate, reasonably be expected to result in a
Material Adverse Effect as to CEMEX and its subsidiaries taken as a whole, and
(C) the aggregate number of shares of CEMEX Common Stock issued or issuable
pursuant to the exercise of all warrants, options, subscriptions, purchase
rights or conversion or exchange rights in any convertible securities does not
materially exceed the aggregate number of such shares issued or so issuable as
reflected in the Financial Statements except, in the case of clauses (A), (B)
and (C), as disclosed to the Seller in writing or otherwise publicly disclosed
by CEMEX.

(iii) The Financial Statements did not, at the time of their
filing with the MSB, contain an untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made when they were so filed,
not misleading.

(e)  No Insolvency Proceedings. As of the date hereof,

(i)   there is not pending any Insolvency Proceeding with regard
to CEMEX or any Material Subsidiary of CEMEX,

(ii)  no decree or order for relief in respect of CEMEX or any
Material Subsidiary of CEMEX has been entered in any Insolvency Proceeding, and

(iii) neither CEMEX or any Material Subsidiary of CEMEX has:

relief in respect of CEMEX or any Material Subsidiary of CEMEX in any
Insolvency Proceeding,

(B)   filed a petition or answer or consent in any
Insolvency Proceeding seeking reorganization, concurso mercantil, or relief
under any applicable law of Mexico, the United States of America or other
applicable jurisdiction or any political subdivision thereof or other
applicable law,

sjdc-1278732.4
16

competent jurisdiction determines that one of the Parties has
materially breached this Agreement and that such breach is not subject
to cure within a reasonable period of time;

(iii) Either Party may terminate this Agreement by giving
written notice to each other Party if the Closing has not occurred by
the close of business on (A) October 15, 2002, unless both Parties
elect in writing to extend the date for Closing in accordance with
this Article VI(15)(a)(iii), or (B) if said extension occurs, the date
as to which Closing has been extended in accordance herewith
(provided, however, that the right to terminate this Agreement under
this Article VI(15)(a)(iii) shall not be available to any Party whose
failure to fulfill any obligation of such Party under this Agreement
has been the cause of or resulted in the failure of the transactions
contemplated herein to be completed on or before such date);

(iv)  Either Party may terminate this Agreement by giving
written notice to each other Party if the first Subsequent Closing
Date has not occurred by the close of business on (A) March 31, 2004,
unless both Parties elect in writing to extend the date for such
Subsequent Closing Date in accordance with this Article VI(15)(a)(iv),
or (B) if said extension occurs, the date as to which such Subsequent
Closing Date has been extended in accordance herewith (provided,
however, that the right to terminate this Agreement under this Article
VI(15)(a)(iv) shall not be available to any Party whose failure to
fulfill any obligation of such Party under this Agreement has been the
cause of or resulted in the failure of the transactions contemplated
herein to be completed on or before such date); and

(v)   Either Party may terminate this Agreement by giving
written notice to the other Party if a court of competent jurisdiction
or other governmental authority has issued a final order, decree or
ruling, or taken any other action, having the effect of permanently
restraining, enjoining or otherwise prohibiting any of the
transactions contemplated herein, and all appeals with respect to such
order, decree, ruling or action have been exhausted or the time for
appeal of such order, decree, ruling or action shall have expired.

(b)   In the event of the termination of this Agreement pursuant
to Article VI(15)(a), written notice thereof shall promptly be given to the
other Party, whereupon this Agreement shall terminate, all further
obligations of the Parties hereunder and under the Escrow Agreement to
satisfy the conditions precedent to the Closing or any Subsequent Closing
Date that has not yet occurred shall terminate, and the transactions
contemplated hereby and thereby shall be abandoned without further action
by either of the Parties. Any termination pursuant to this Article VI(15)
shall be without liability to the Parties, except to the extent that there
shall have occurred any breach of this Agreement or the Escrow Agreement,
as to each of which all legal and other remedies

sjdc-1278732.4                         17

under this Agreement or the Escrow Agreement of the Party(ies) adversely
affected shall survive and be enforceable for a period of two years from
the date of termination.

(c)   Notwithstanding anything to the contrary herein, the
obligations of CEMEX to pay the Base Deferral Fee and other amounts due
hereunder shall survive any termination of this Agreement."

Section 13. Miscellaneous Provisions.

(a)  Expenses. All reasonable expenses, including legal fees, incurred
by either Party in connection with the Amendments shall be borne by CEMEX, which
shall promptly upon request reimburse the Seller for such amounts.

(b)  Counterparts. This Amendment No. 2 may be executed simultaneously
in two or more counterparts, each of which shall be deemed an original, but all
of which together shall constitute one and the same instrument.

(c)  Headings. The headings of the Sections of this Amendment No. 2
are inserted for convenience only and shall not constitute a part thereof or
affect in any way the meaning or interpretation of this Amendment No. 2.

(d)  Severability. Each of the representations and undertakings in
this Amendment No. 2 shall be construed separately and severably; if, in any
judicial proceeding, a court shall refuse to enforce any of the provisions
included in any paragraph or subparagraph of this Amendment No. 2, then the
remaining provisions shall be deemed separate and shall continue in full force
and effect.

(e)  CPO Certificate. The Parties agree that this Amendment No. 2
supersedes the CPO Certificate dated March 17, 2003 delivered by CEMEX to the
Seller pursuant to the SPA and that such CPO Certificate shall therefore be of
no force and effect between the Parties.

(f)  International Transaction. This is an international transaction
in which the specification of Dollars is of the essence, and such currency shall
be the currency of account in all events. The payment obligations of CEMEX
hereunder shall not be discharged by payment in another currency, whether
pursuant to a judgment or otherwise, to the extent that the amount so paid on
prompt conversion to Dollars in the United States of America under normal
banking procedures does not yield the amount of Dollars then due. In the event
that any payment by CEMEX, whether pursuant to a judgment or otherwise, upon
conversion and transfer, does not result in the full payment of such amount of
Dollars at the place such amount is due, the Seller shall be entitled to demand
immediate payment of, and shall have a separate cause of action against CEMEX
for, the additional amount necessary to yield the full amount of Dollars then
due. In the event the Seller, upon the conversion of such judgment into Dollars,
shall receive, as a result of currency exchange rate fluctuations, an amount
greater than that to which it was entitled, CEMEX shall be entitled to immediate
reimbursement of the excess amount.

sjdc-1278732.4                         18

Section 14. No Other Changes. Except as expressly amended hereby, all other
provisions of the SPA shall remain in full force and effect.

1.       The first sentence of Article I(5) of the Agreement is hereby
amended in its entirety to read as follows:

"5. Adjustments to the Number of CPOs. The Number of
CPOs to be delivered on any Subsequent Closing Date shall be
adjusted from time to time as set forth in this Article I(5);
provided, however, that with respect to any Tranche (i) no
adjustment shall be made for any dividend or other
distribution paid or made on the CEMEX Common Stock on or
after the Original Subsequent Closing Date for such Tranche if
the aggregate value (as determined in good faith by the board
of directors of CEMEX) of all dividends or other distributions
paid or made on the CEMEX Common Stock from the Original
Subsequent Closing Date for such Tranche until and including
the Subsequent Closing Date for such Tranche (and including
the value of such dividend or distribution) does not exceed 5%
of the current market capitalization (determined as provided
in paragraph (g) of this Article I(5)) of the CEMEX Common
Stock on the date fixed for the determination of stockholders
entitled to receive such dividend or distribution, and (ii) if
a dividend or other distribution is paid or made on the CEMEX
Common Stock on or after the Original Subsequent Closing Date
for such Tranche and the aggregate value (as determined in
good faith by the board of directors of CEMEX) of all
dividends or other distributions paid or made on the CEMEX
Common Stock from the Original Subsequent Closing Date for
such Tranche until and including the Subsequent Closing Date
for such Tranche

(and including the value of such dividend or distribution)
(such aggregate value, being referred to as the "Aggregate
Value") exceeds 5% of the current market capitalization
(determined as provided in paragraph (g) of this Article I(5))
of the CEMEX Common Stock on the date fixed for the
determination of stockholders entitled to receive such
dividend or distribution (such 5% of the current market
capitalization, being referred to as the "Dividend Cap"), then
the Number of CPOs to be delivered on the Subsequent Closing
Date for such Tranche shall be adjusted as set forth in this
Article I(5) as if such dividend or other distribution
consisted of a dividend or distribution of only such portion
of such dividend or distribution as has a value (determined in
the same manner as the Aggregate Value referred to above is
determined) equal to the amount by which the Aggregate Value
exceeds the Dividend Cap."

2.       Article IV(5) of the Agreement is hereby deleted in its
entirety and amended to read as follows:

"5.      OMITTED."

3.       Attached hereto as Exhibit A is a detailed calculation showing
(i) the increased Number of CPOs which have been adjusted for
the cash and stock portion of the dividend paid by CEMEX on
June 5, 2003, and (ii) the Base Deferral Fee payment schedule
as of the date hereof.

4.       This Amendment No. 3 may be executed simultaneously in two or
more counterparts, each of which shall be deemed an original,
but all of which together shall constitute one and the same
instrument.

5.       Except as expressly amended hereby, all other provisions of
the Agreement shall remain in full force and effect.

6.       THIS AMENDMENT NO. 3 AND ALL RIGHTS AND REMEDIES AMONG CEMEX
AND THE SELLER SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO ITS CONFLICTS OF LAW DOCTRINE OTHER THAN NEW YORK

and

GIMV N.V.

483741.01-New York S4A

STOCK PURCHASE AGREEMENT

STOCK PURCHASE AGREEMENT, dated as of July 12, 2002 (the "Agreement"),
between CEMEX, S.A. de C.V., a corporation organized under the laws of the
United Mexican States ("CEMEX"), and GIMV N.V., a limited liability company
organized under the laws of Belgium (the "Seller"). The Seller and CEMEX are
herein sometimes referred to individually as a "Party" and collectively as the
"Parties."

WITNESSETH:

WHEREAS, the Seller beneficially owns 84,763 shares (the "Seller's
Shares") of common stock of CEMEX Asia Holdings, Ltd. ("CAH");

WHEREAS, this Agreement contemplates a transaction in which CEMEX will
purchase from the Seller, and the Seller will sell to CEMEX, the Seller's
Shares;

WHEREAS, subject to the terms and conditions set forth herein, on or
before each Subsequent Closing Date (as hereinafter defined), CEMEX will deliver
or cause to be delivered to the Seller (or the Seller's designee) either (i)
CEMEX Ordinary Participation Certificates ("CPOs"), each CPO representing two
shares of series A common stock ("A Shares") and one share of series B common
stock ("B Shares" and, together with the A Shares, the "CEMEX Common Stock") of
CEMEX or (ii) cash sufficient to purchase the Number of CPOs (as hereinafter
defined), as consideration for the Number of Shares (as hereinafter defined);

WHEREAS, this Agreement sets forth the terms and conditions upon which
the Seller will sell such Seller's Shares to CEMEX; and

WHEREAS, subject to the terms and conditions set forth herein, CEMEX
and the Seller have agreed to enter into (i) an Escrow Agreement by and among
CEMEX, the Seller, and JPMorgan Chase Bank, as escrow agent (the "Escrow
Agent"), to be dated on or prior to the Closing Date (as defined herein),
substantially in the form attached hereto as Exhibit A (the "Escrow Agreement"),
and (ii) a Third Amended and Restated Shareholders Agreement, to be dated on or
prior to the Closing Date, substantially in the form attached hereto as Exhibit
B (the "Amended Shareholders Agreement" and, together with this Agreement and
the Escrow Agreement, the "Transaction Documents"). Capitalized terms used but
not

483741.01-New York S4A

defined herein shall have the respective meanings given to them in the Amended
Shareholders Agreement.

NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties and covenants herein contained, intending to be
legally bound hereby, the Parties agree as follows:

ARTICLE I

PURCHASE AND SALE OF SELLER'S SHARES
------------------------------------

1.   Basic Transaction. (a) On and subject to the terms and conditions
of this Agreement and the Escrow Agreement, on March 31, 2003, June 30, 2003,
September 30, 2003 and December 31, 2003 (or if any such day is not a business
day in each of New York, Mexico and Singapore (a "Business Day"), then the first
day thereafter that is a Business Day)(each a "Subsequent Closing Date"), CEMEX
agrees to purchase from the Seller, and the Seller agrees to sell to CEMEX, the
number of Seller's Shares set forth in the column corresponding to such
Subsequent Closing Date opposite the Seller's name on Schedule A to the Escrow
Agreement (such number of Seller's Shares to be sold on a Subsequent Closing
Date being referred to herein as the "Number of Shares").

(b)  Notwithstanding anything to the contrary contained in the
foregoing Article I(1)(a), at any time from and after Closing, upon prior
written notice to the Seller and all other parties to the Escrow Agreement,
CEMEX may designate any Business Day after the thirtieth day following such
notice and prior to a Subsequent Closing Date as the "Early Subsequent Closing
Date" for such Subsequent Closing Date. Following any such designation, such
Early Subsequent Closing Date shall be deemed to be the Subsequent Closing Date
for all purposes under the Transaction Documents, and references to such
Subsequent Closing Date shall be deemed to be references to such Early
Subsequent Closing Date.

(c)  If at any time or from time to time after the date hereof
and prior to the final Subsequent Closing Date, CEMEX designates an Early
Subsequent Closing Date in respect to the Seller's Shares, or in respect to the
shares of CAH to be acquired by CEMEX in accordance with those separate Stock
Purchase Agreements referred to in Article III(10), CEMEX shall
contemporaneously designate the same Early Subsequent Closing Date for such
other holders of CAH shares and the Seller, as applicable.

483741.01-New York S4A                 2

2.   Purchase Price. On or before each Subsequent Closing Date, CEMEX
shall deliver or cause to be delivered to the Seller (or its designee), as
consideration for the Number of Shares to be purchased by CEMEX on such
Subsequent Closing Date, either (i) a number of CPOs (the "Number of CPOs")
equal to the product obtained by multiplying such Number of Shares times
U.S.$95.00 and dividing such product by U.S.$4.998, or (ii) an amount (the
"Acquisition Amount") of cash in immediately available United States Dollars
equal to the sum of (A) the purchase price of the Number of CPOs, plus (B) all
transaction costs, including brokerage fees and commissions, currency exchange
costs and other fees and expenses reasonably estimated to be incurred in
connection with the acquisition and deposit of such Number of CPOs to the
Seller's Depositary Account (as defined in the Escrow Agreement); provided,
however, that should CEMEX elect to deliver the Acquisition Amount, then CEMEX
shall, in accordance with Section 5(b)(iv) of the Escrow Agreement, (x) deliver
such cash to the Escrow Agent sufficiently in advance of the relevant Subsequent
Closing Date to permit the Escrow Agent to arrange for the purchase of the
Number of CPOs with such funds, and to have such CPOs available for delivery to
the Seller (or its nominee) on such Subsequent Closing Date, and (y) give
written instructions to the Escrow Agent regarding the procedures for such
purchase; and further provided, however, that CEMEX's obligation to deposit the
Number of CPOs on any Subsequent Closing Date to the Seller's Depositary Account
(as defined in the Escrow Agreement) shall not be satisfied until such Number of
CPOs is so deposited. The Number of CPOs to be delivered on a Subsequent Closing
Date pursuant to the preceding sentence shall be adjusted from time to time as
set forth in Article I(5) below.

3.   Closing. Subject to the conditions set forth in Article V below,
the closing to occur on the Closing Date contemplated by this Agreement (the
"Closing") shall occur at the offices of Skadden, Arps, Slate, Meagher & Flom
LLP, 4 Times Square, New York, NY 10036, at 10:00 am, local time, on July 12,
2002 or at such other time and place, no later than the thirtieth day following
such date, as shall be agreed by the Parties (such date being referred to herein
as the "Closing Date").

483741.01-New York S4A                 3

4.   Deliveries at the Closing.

(a)  At the Closing, subject to the terms and conditions set
forth herein, the Seller will deliver:

(i)   to CEMEX, (A) a counterpart to the Escrow Agreement
and the Amended Shareholders Agreement, each duly executed by the Seller,
and (B) the officer's certificate contemplated by Article V(1)(e);

(ii)  to the Escrow Agent, (A) a counterpart to the Escrow
Agreement, duly executed by the Seller, and (B) the documents and
instruments comprising the Deposit (as defined in the Escrow Agreement);
and

(iii) all other previously undelivered documents required by
the Transaction Documents to be delivered by the Seller at or prior to the
Closing Date.

(b)  At the Closing, subject to the terms and conditions set
forth herein, CEMEX will deliver to the Seller:

(i)   counterparts to the Escrow Agreement and the Amended
Shareholders Agreement, each duly executed by all of the parties thereto on
their own behalf;

(ii)  the officer's certificate contemplated by Article
V(2)(g);

(iii) a release substantially in the form attached hereto as
Exhibit C (the "Release"), duly executed by CAH;

(iv)  a true and complete copy of the Amended and Restated
Charter of CAH (substantially in the form of Exhibit D attached hereto)
(the "Amended and Restated Charter"), as will be lodged by CAH within 14
days from the Closing Date in the Office of the Registrar of Companies and
Business, Singapore (the "Registrar"), conforming CAH's Charter to the
Amended Shareholders Agreement; and

483741.01-New York S4A                 4

(v)   all other previously undelivered documents required by
the Transaction Documents to be delivered by CEMEX at or prior to the
Closing Date.

5.   Adjustments to the Number of CPOs. The Number of CPOs to be
delivered on any Subsequent Closing Date shall be adjusted from time to time as
set forth in this Article I(5); provided, however, that no adjustment shall be
made for any dividend or other distribution paid to or for the benefit of the
Seller pursuant to Article IV(5) below.

(a)  In case CEMEX shall pay or make a dividend or other
distribution on all or any portion of the CEMEX Common Stock exclusively in
CEMEX Common Stock or shall pay or make a dividend or other distribution on any
other class of capital stock of CEMEX which dividend or distribution includes
CEMEX Common Stock, the Number of CPOs as of the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be increased by multiplying
such Number of CPOs by a fraction of which the denominator shall be the number
of shares of all CEMEX Common Stock outstanding at the close of business on the
date fixed for such determination and the numerator shall be the sum of such
number of shares and the total number of shares of CEMEX Common Stock
constituting such dividend or other distribution, such increase to become
effective immediately after the opening of business on the day following the
date fixed for such determination.

(b)  In case CEMEX shall pay or make a dividend or other
distribution on all or any portion of the CEMEX Common Stock consisting of, or
shall otherwise issue to holders of all or any portion of the CEMEX Common
Stock, rights, warrants or options entitling the holders thereof to subscribe
for or purchase shares of any class of CEMEX Common Stock at a price per share
less than the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date fixed for the
determination of stockholders entitled to receive such rights, warrants or
options (each such class, an "affected class"), the Number of CPOs in effect at
the opening of business on the day following the date fixed for such
determination shall be increased by multiplying such number by a fraction of
which the denominator shall be the number of shares of all CEMEX Common Stock
outstanding at the close of business on the date fixed for such determination
plus, for each affected class, the number of shares of such class which the
aggregate of the offering price of the total number of shares of such class so
offered for subscription or purchase would purchase at such current market price
and the numerator shall be the number of shares of all CEMEX Common Stock
outstand-

483741.01-New York S4A                 5

ing at the close of business on the date fixed for such determination plus, for
each affected class, the number of shares of such class so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination.

(c)  In case all or any portion of the outstanding CEMEX Common
Stock shall be subdivided into a greater number of shares of CEMEX Common Stock,
the Number of CPOs in effect at the opening of business on the day following the
day upon which such subdivision becomes effective shall be proportionately
increased (based on the change in the total number of shares of all CEMEX Common
Stock, without regard to classes), and, conversely, in case all or any portion
of the outstanding CEMEX Common Stock shall be combined into a smaller number of
shares of CEMEX Common Stock, the Number of CPOs in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be proportionately reduced (based on the change in the total
number of shares of all CEMEX Common Stock, without regard to classes), such
increase or reduction, as the case may be, to become effective immediately after
the opening of business on the day following the day upon which such subdivision
or combination becomes effective.

(d)  Subject to the last sentence of this paragraph (d), in case
CEMEX shall, by dividend or otherwise, distribute to holders of all or any
portion of the CEMEX Common Stock evidences of CEMEX's indebtedness, shares of
any class of capital stock, securities, cash or property (excluding any rights,
warrants or options referred to in paragraph (b) of this Article I(5), any
dividend or distribution paid exclusively in cash and any dividend or
distribution referred to in paragraph (a) of this Article I(5)), the Number of
CPOs shall be increased so that the same shall equal the number determined by
multiplying the Number of CPOs in effect immediately prior to the effectiveness
of the increase in the Number of CPOs contemplated by this paragraph (d) by a
fraction of which the denominator shall be the current market capitalization
(determined as provided in paragraph (g) of this Article I(5)) of the CEMEX
Common Stock on the date fixed for such distribution less the fair market value
(as determined in good faith by the board of directors of CEMEX, whose
determination shall be conclusive and shall, in the case of securities being
distributed for which prior thereto there is an actual or when issued trading
market, be no less than the value determined by reference to the average of the
closing prices in such market over the period specified in the succeeding
sentence), on the date of such effectiveness, of the evidences of indebtedness,
shares of capital stock, securities, cash and other property so distributed and
the numerator shall be such current market capitalization, such increase to
become effective immediately prior to the opening of

483741.01-New York S4A                 6

business on the day following the date fixed for the payment of such
distribution (such date being referred to as the "Reference Date"). If the board
of directors of CEMEX determines the fair market value of any distribution for
purposes of this paragraph (d) by reference to the actual or when issued trading
market for any securities comprising such distribution, it must in doing so
consider the prices in such market over the same period used in computing the
current market capitalization pursuant to paragraph (g) of this Article I(5).
For purposes of this paragraph (d), any dividend or distribution that includes
shares of CEMEX Common Stock or rights, warrants or options to subscribe for or
purchase shares of CEMEX Common Stock shall be deemed instead to be (A) a
dividend or distribution of the evidences of indebtedness, cash, shares of
capital stock, other securities or other property other than such shares of
CEMEX Common Stock or such rights, warrants or options (making any increase in
the Number of CPOs required by this paragraph (d)) immediately followed by (B) a
dividend or distribution of such shares of CEMEX Common Stock or such rights,
warrants or options (making any further increase in the Number of CPOs required
by paragraph (a) or (b) of this Article I(5), except (A) the Reference Date of
such dividend or distribution as defined in this paragraph (d) shall be
substituted as "the date fixed for the determination of stockholders entitled to
receive such rights, warrants or options" and "the date fixed for such
determination" within the meaning of paragraphs (a) and (b) of this Article I(5)
and (B) any shares of CEMEX Common Stock included in such dividend or
distribution shall not be deemed "outstanding at the close of business on the
date fixed for such determination" within the meaning of paragraph (a) of this
Article I(5)).

(e)  In case CEMEX shall, by dividend or otherwise, make a
distribution to holders of all or any portion of the CEMEX Common Stock
exclusively in cash in an aggregate amount that, together with (A) the aggregate
amount of any other distributions to holders of all or any portion of the CEMEX
Common Stock made exclusively in cash within the 12 months preceding the date of
payment of such distribution and in respect of which no adjustment in the Number
of CPOs pursuant to this paragraph (e) has been made and (B) the aggregate of
any cash plus the fair market value (as determined in good faith by the board of
directors of CEMEX, whose determination shall be conclusive), as of the
expiration of the tender or exchange offer referred to below, of consideration
payable in respect of any tender or exchange offer by CEMEX or a subsidiary of
CEMEX for all or any portion of the CEMEX Common Stock concluded within the 12
months preceding the date of payment of such distribution and in respect of
which no adjustment in the Number of CPOs pursuant to paragraph (f) of this
Article I(5) has been made, exceeds 12.5% of the current market capitalization
of the CEMEX Common Stock (determined as provided in paragraph (g) of this
Article I(5)) on the date fixed for the determination

483741.01-New York S4A                 7

of stockholders entitled to receive such distribution, the Number of CPOs shall
be increased so that the same shall equal the number determined by multiplying
the Number of CPOs in effect immediately prior to the effectiveness of the
number increase contemplated by this paragraph (e) by a fraction of which the
denominator shall be the current market capitalization of the CEMEX Common Stock
(determined as provided in paragraph (g) of this Article I(5)) on the date fixed
for such distribution less the amount of cash distributed in such distribution
and the numerator shall be such current market capitalization, such increase to
become effective immediately prior to the opening of business on the day
following the date fixed for the payment of such distribution.

(f)  In case a tender or exchange offer made by CEMEX or any
subsidiary of CEMEX for all or any portion of the CEMEX Common Stock shall
expire and such tender or exchange offer shall involve an aggregate
consideration having a fair market value (as determined in good faith by the
board of directors of CEMEX, whose determination shall be conclusive) at the
last time (the "Expiration Time") tenders or exchanges may be made pursuant to
such tender or exchange offer (as it may be amended) that, together with (A) the
aggregate of the cash plus the fair market value (as determined in good faith by
the board of directors of CEMEX, whose determination shall be conclusive), as of
the expiration of the other tender or exchange offer referred to below, of
consideration payable in respect of any other tender or exchange offer by CEMEX
or a subsidiary of CEMEX for all or any portion of the CEMEX Common Stock
concluded within the 12 months preceding the Expiration Time and in respect of
which no adjustment to the Number of CPOs pursuant to this paragraph (f) has
been made and (B) the aggregate amount of any distributions to all holders of
the CEMEX Common Stock made exclusively in cash within the 12 months preceding
the Expiration Time and in respect of which no adjustment to the Number of CPOs
pursuant to paragraph (e) of this Article I(5) has been made, exceeds 12.5% of
the current market capitalization of the CEMEX Common Stock (determined as
provided in paragraph (g) of this Article I(5)) at the Expiration Time
(calculated by treating as outstanding any shares tendered for sale or
exchange), the Number of CPOs shall be increased so that the same shall equal
the number determined by multiplying the Number of CPOs in effect immediately
prior to the Expiration Time by a fraction of which the denominator shall be (i)
the current market capitalization of the CEMEX Common Stock (determined as
provided in paragraph (g) of this Article I(5)) at the Expiration Time
(calculated by treating as outstanding any shares tendered for sale or exchange)
minus (ii) the fair market value (determined as aforesaid) of the aggregate
consideration payable to stockholders pursuant to such tender or exchange offer
based on the acceptance (up to any maximum specified in the terms of the tender
or exchange offer) of all shares validly

483741.01-New York S4A                 8

tendered for sale or exchange and not withdrawn as of the Expiration Time (the
shares deemed so accepted, up to any such maximum, being referred to as the
"Purchased Shares") and the numerator shall be such current market
capitalization at the Expiration Time (calculated by reducing the relevant
number of outstanding shares by the number of Purchased Shares), such increase
to become effective immediately prior to the opening of business on the day
following the Expiration Time.

(g)  For the purpose of any computation under this paragraph and
paragraphs (b), (d) and (e) of this Article I(5), the current market price per
share of any class of CEMEX Common Stock on any date in question shall be deemed
to be the average of the daily Closing Prices (as defined herein) for such class
for the five consecutive Trading Days (as defined herein) selected by CEMEX
commencing not more than 20 Trading Days before, and ending not later than, the
date in question; provided, however, that (A) if the "ex" date (as hereinafter
defined) for any event (other than the issuance or distribution requiring such
computation) that requires an adjustment to the Number of CPOs pursuant to
paragraph (a), (b), (c), (d), (e) or (f) above ("Other Event") occurs on or
after the 20th Trading Day prior to the date in question and prior to the "ex"
date for the issuance or distribution requiring such computation (the "Current
Event"), the Closing Price for such class for each Trading Day prior to the "ex"
date for such Other Event shall be adjusted by multiplying such Closing Price by
the reciprocal fraction by which the Number of CPOs is so required to be
adjusted as a result of such Other Event, (B) if the "ex" date for any Other
Event occurs after the "ex" date for the Current Event and on or prior to the
date in question, the Closing Price for such class for each Trading Day on and
after the "ex" date for such Other Event shall be adjusted by multiplying such
Closing Price by the same fraction by which the Number of CPOs is so required to
be adjusted as a result of such Other Event, (C) if the "ex" date for any Other
Event occurs on the "ex" date for the Current Event, one of those events shall
be deemed for purposes of clauses (A) and (B) of this proviso to have an "ex"
date occurring prior to the "ex" date for the other event, and (D) if the "ex"
date for the Current Event is on or prior to the date in question, after taking
into account any adjustment required pursuant to clause (B) of this proviso, the
Closing Price for such class for each Trading Day on or after such "ex" date
shall be adjusted by adding thereto an amount calculated by dividing (1) the
amount of any cash plus the fair market value on the date in question (as
determined in good faith by the board of directors of CEMEX (in a manner
consistent with any determination of such value for purposes of paragraph (d) or
(e) of this Article I(5)), whose determination shall be conclusive) of the
rights, warrants, options, evidences of indebtedness, shares of capital stock,
securities or other property being distributed by (2) the number of all shares
of CEMEX Common Stock

483741.01-New York S4A                 9

outstanding as of the close of business on the day before such "ex" date. For
the purpose of any computation under paragraph (f) of this Article I(5), the
current market price per share of any class of CEMEX Common Stock on any date in
question shall be deemed to be the average of the daily Closing Prices for the 5
consecutive Trading Days selected by CEMEX commencing on or after the latest
(the "Commencement Date") of (A) the date 20 Trading Days before the date in
question, (B) the date of commencement of the tender or exchange offer requiring
such computation and (C) the date of the last amendment, if any, of such tender
or exchange offer involving a change in the maximum number of shares for which
tenders are sought or a change in the consideration offered, and ending not
later than the date of the Expiration Time of such tender or exchange offer
(which shall occur on a day no earlier than the last of the 5 consecutive
trading days beginning on the Commencement Date); provided, however, that if the
"ex" date for any Other Event (other than the tender or exchange offer requiring
such computation) occurs on or after the Commencement Date and on or prior to
the date of the Expiration Time for the tender or exchange offer requiring such
computation, the Closing Price for such class for each Trading Day prior to the
"ex" date for such Other Event shall be adjusted by multiplying such Closing
Price by the reciprocal fraction by which the Number of CPOs is so required to
be adjusted as a result of such other event. For the purpose of any computation
under paragraph (d), (e) or (f) of this Article I(5), the current market
capitalization of the CEMEX Common Stock on any day shall be deemed to be the
sum of the market values for each class of CEMEX Common Stock on such day. For
each such class, the market value on any day shall be deemed to equal the
current market price per share for such class on such day, multiplied by the
number of shares of such class outstanding on such day; provided that, in
determining such number of outstanding shares on such day, no effect shall be
given to any change in the number of such shares outstanding attributable to any
event for which an adjustment was made to any Closing Price used to determine
such current market price pursuant to clause (B) or (D) of the proviso to the
second preceding sentence and provided, further, that the same 5 Trading Days
shall be used to calculate the current market price for each class of CEMEX
Common Stock. Similarly, in determining the number of shares of all CEMEX Common
Stock outstanding on the relevant date for the purpose of calculating any
adjustment in the Number of CPOs pursuant to paragraph (b) of this Article I(5),
no effect shall be given to any change in the number of such shares outstanding
attributable to any event for which adjustment was made pursuant to such clause
(B) or (D) to any Closing Price used to determine the current market price of an
affected class for the purpose of calculating such adjustment. For purposes of
this paragraph, the term "ex" date, (A) when used with respect to any issuance
or distribution, means, with respect to any class of CEMEX Common Stock, the
first date on which such class trades regular way on the relevant

483741.01-New York S4A                 10

exchange or in the relevant market from which the Closing Price was obtained
without the right to receive such issuance or distribution, (B) when used with
respect to any subdivision or combination of shares of CEMEX Common Stock, means
the first date on which such class trades regular way on such exchange or in
such market after the time at which such subdivision or combination becomes
effective, and (C) when used with respect to any tender or exchange offer means
the first date on which such class trades regular way on such exchange or in
such market after the Expiration Time of such tender or exchange offer.

"Closing Price" means (i) in respect of any class of Common Stock, for
any Trading Day, the last reported sale price, regular way, of such Common Stock
or, in case no such reported sale takes place on such Trading Day, the average
of the reported closing bid and asked prices, regular way, of such Common Stock
on the Mexican Stock Exchange (the Bolsa Mexicana de Valores, S.A. de C.V.) or,
if such Common Stock is not listed or admitted for trading on such exchange, the
average of the reported closing bid and asked prices of such Common Stock as
furnished by any three leading Mexican Stock Exchange member firms selected from
time to time by CEMEX for that purpose and (ii) in respect of any class of CPOs
representing Common Stock for any Trading Day, the last reported sale price,
regular way, of or, in case no such reported sale takes place on such Trading
Day, the average of the reported closing bid and asked prices, regular way, for
such CPOs, on the Mexican Stock Exchange or, if such CPOs are not listed or
admitted for trading on such exchange, the average of the reported closing bid
and asked prices of such CPOs as furnished by any three leading Mexican Stock
Exchange member firms selected from time to time by CEMEX for that purpose.

"Trading Day" means each Monday, Tuesday, Wednesday, Thursday and
Friday, other than any day on which the Mexican Stock Exchange is not open for
trading.

(h)  (i)   In case CEMEX shall issue or sell any shares of any
class of CEMEX Common Stock without consideration or at a price per share less
than 90% of the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date of such issuance
or sale, the Number of CPOs in effect at the opening of business on the day
following the date of such issuance or sale shall be increased by:

(A)  multiplying the Number of CPOs in effect at the close
of business on the day immediately preceding the date of
such issuance or sale by

483741.01-New York S4A                 11

(B)   a fraction, of which

(1) the numerator shall be the number of shares of
CEMEX Common Stock outstanding at the close of
business on the date immediately preceding such
issuance or sale, plus the number of shares of
CEMEX Common Stock so issued or sold, and

(2) the denominator shall be the number of shares of
CEMEX Common Stock outstanding at the close of
business on the date immediately preceding such
issuance or sale, plus the number of shares of
CEMEX Common Stock which the aggregate
consideration, if any, received (or to be
received) by CEMEX for the total number of such
additional shares of CEMEX Common Stock so issued
or sold would purchase at such current market
price per share.

(ii)  For the purposes of this Article I(5)(h), the issuance
of any warrants, options, subscriptions, or purchase rights with respect to
shares of any class of CEMEX Common Stock and the issuance of any
securities convertible into or exchangeable for shares of any class of
CEMEX Common Stock (or the issuance of any warrants, options or any rights
with respect to such convertible or exchangeable securities) shall be
deemed an issuance of such shares of such class of CEMEX Common Stock at
such time if the Net Consideration Per Share (as hereinafter determined)
which may be received by CEMEX for such CEMEX Common Stock shall be less
than 90% of the current market price per share (determined as provided in
paragraph (g) of this Article I(5)) of such class on the date of such
issuance. Any obligation, agreement, or undertaking to issue warrants,
options, subscriptions, or purchase rights at any time in the future shall
be deemed to be an issuance at the time such obligation, agreement or
undertaking is made or arises.

483741.01-New York S4A                 12

(iii) No adjustment to the Number of CPOs shall be made
under this Article I(5)(h) upon the sale or issuance (or deemed issuance)
of any shares of CEMEX Common Stock pursuant to:

(A)   the exercise of any warrants, options, subscriptions,
or purchase rights or the exercise of any conversion or
exchange rights in any convertible securities, in each case,
outstanding as of the close of business on the date hereof;

(B)   any employee stock option, purchase or incentive plan,
whether or not existing on the date hereof;

(C)   any of the events referred to in paragraphs (a), (b),
(c), (d), (e) and (f) of this Article I(5);

(D)   anti-dilution provisions contained in any of the
securities referred to in the preceding clauses (A), (B) and
(C) hereof; or

(E)   if any adjustment shall previously have been made, or
deemed not required hereunder, upon the issuance of any such
warrants, options, or subscription or purchase rights or
upon the issuance of any convertible securities (or upon the
issuance of any warrants, options or any rights therefor) as
above provided.

(iv)  If the Net Consideration Per Share of any such
warrants, options, subscriptions, or purchase rights or convertible
securities is decreased from time to time, then, upon the effectiveness of
each such decrease, the Number of CPOs shall be adjusted to such Number of
CPOs as would have obtained (A) had the adjustments made upon the issuance
of such warrants, options, rights, or convertible securities been made upon
the basis of the decreased Net Consideration Per Share of such securities,
and (B) had adjustments made to the Number of CPOs since the date of
issuance of such securities been made to the Number of CPOs as adjusted
pursuant to clause (A) above. Any adjustment of the Number of CPOs with
respect to this paragraph which relates to warrants, options,
subscriptions, purchase rights or convertible securities with respect to
shares of CEMEX Common Stock shall be disregarded if, as, when and to the
extent such warrants, options, subscriptions, purchase rights or

483741.01-New York S4A                 13

convertible securities with respect to shares of CEMEX Common Stock
shall be disregarded if, as, when and to the extent such warrants, options,
subscriptions, purchase rights or convertible securities expire or are
canceled without being exercised or converted, so that the Number of CPOs
effective immediately upon such cancellation or expiration shall be the
same as the Number of CPOs in effect at the time of the issuance of the
expired or canceled warrants, options, subscriptions, purchase rights, or
convertible securities with such additional adjustments as would have been
made to that Number of CPOs had the expired or canceled warrants, options,
subscriptions, purchase rights or convertible securities not been issued.

(v)   "Net Consideration Per Share" shall mean the total
amount of consideration, if any, received by CEMEX as of the date of
issuance in respect to the issuance of such warrants, options,
subscriptions, or other purchase rights or convertible or exchangeable
securities, plus the minimum amount of consideration, if any, payable to
CEMEX upon exercise or conversion thereof, divided by the aggregate number
of shares of CEMEX Common Stock that would be issued if all such warrants,
options, subscriptions, or other purchase rights or convertible or
exchangeable securities were exercised, exchanged, or converted, without
giving effect to any possible future upward price adjustments or rate
adjustments.

(vi)  If part or all of the consideration received by CEMEX
in respect to the issuance of CEMEX Common Stock or of any of the
securities described in this Article I(5)(h) consists of property other
than cash, such consideration shall be deemed to have a fair market value
reasonably determined in good faith by the board of directors of CEMEX.

(i)  No adjustment in the Number of CPOs shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Number of CPOs; provided, however, that any adjustments which by reason of this
paragraph (i) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment.

(j)  In addition to the adjustments in the Number of CPOs
required by paragraphs (a), (b), (c), (d), (e), (f) and (h) of this Article
I(5), CEMEX may from time to time in its discretion make such increases in the
Number of CPOs as it considers to be advisable in order to avoid or diminish any
Mexican income tax to any holders of shares of CEMEX Common Stock resulting from
any dividend or distribution of stock or issuance of rights or warrants to
purchase or subscribe for

483741.01-New York S4A                 14

stock or from any event treated as such for income tax purposes or for any other
reasons.

(k)  For purposes of calculating the number of shares of CEMEX
Common Stock at any time outstanding or the number of shares of CEMEX Common
Stock acquired in any tender or exchange offer, the number of shares of CEMEX
held in its treasury shall not be included.

(l)  CEMEX shall ensure that the time for determining the
stockholders entitled to receive any dividend, issuance or other distribution in
respect of any CEMEX Common Stock, the time of effectiveness of any subdivision
or combination of any CEMEX Common Stock and the expiration time of any tender
or exchange offer made by CEMEX or any subsidiary of CEMEX for any CEMEX Common
Stock shall be at or after the close of business on the date fixed for
determining such stockholders, or on the date of such effectiveness or
expiration, as the case may be, so that (whether or not any adjustment to the
Number of CPOs is required pursuant to this Article I(5)) any Subsequent Closing
Date occurring on such date shall be deemed to have occurred prior to such
relevant time on such date.

(m)  Whenever the Number of CPOs is adjusted as herein provided,
CEMEX shall promptly deliver to the Seller a notice setting forth the adjusted
Number of CPOs and showing in reasonable detail the facts upon which such
adjustment is based.

(n)  In the event that CEMEX shall be a party to any transaction
(including any (i) recapitalization or reclassification of all or any portion of
the CEMEX Common Stock (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination of all or any portion of the CEMEX Common Stock), (ii)
consolidation of CEMEX with, or merger of CEMEX into, any other person, or any
merger of another person into CEMEX (other than a merger which does not result
in a reclassification, conversion, exchange or cancellation of any outstanding
CEMEX Common Stock), (iii) conveyance, transfer, sale or lease of all or
substantially all of the assets of CEMEX, or (iv) compulsory share exchange)
pursuant to which the CPOs are converted into the right to receive other
securities, cash or other property, then lawful provision shall be made as part
of the terms of such transaction providing that the Seller shall have the right
thereafter, to purchase the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, reclassification,
conveyance, transfer or sale by a holder of the Number of CPOs which the Seller
was entitled to purchase immediately prior to such consolidation,

483741.01-New York S4A                 15

merger, reclassification, conveyance, transfer or sale (the "Transaction
Consideration"), assuming the Seller is not a Person with which CEMEX
consolidated or into which CEMEX merged or which merged into CEMEX, or to which
such sale or transfer was made, as the case may be (a "Constituent Person"), or
an Affiliate of a Constituent Person, and failed to exercise his right of
election, if any, as to the kind or amount of securities, cash or other property
receivable upon such consolidation, merger, reclassification, conveyance,
transfer or sale (provided that if the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer is
not the same for each CPO in respect of which such rights of election shall not
have been exercised ("non-electing share"), then for the purpose of this Article
I(5) the kind and amount of securities, cash and other property receivable upon
such consolidation, merger, sale or transfer by each non-electing share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
non-electing shares).

CEMEX or the person formed by such consolidation or resulting
from such merger or which acquired such assets or CEMEX's shares, as the case
may be, shall execute and deliver to the Seller a notice setting forth the
Seller's rights as provided above. Such notice shall provide for adjustments
which, for events subsequent to the effective date of such notice, shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Article I(5). The above provisions of this Article I(5) shall similarly apply to
successive transactions of the foregoing type.

483741.01-New York S4A                 16

2.   Authorization. The Seller has all necessary power and authority

delivery of the Transaction Documents and the consummation of the transactions
on its part contemplated thereby. Each of the Transaction Documents and any
other instrument to be executed and delivered by the Seller at the Closing or on
any Subsequent Closing Date is, or will be when executed and delivered, the
valid and binding agreement of the Seller enforceable against it in accordance
with its terms, except to the extent that (i) such validity, binding effect or
enforceability may be subject to bankruptcy, insolvency, reorganization,

transactions contemplated thereby, including, without limitation, any short
sales and hedging transactions to be effected by the Seller, will (i) violate
any provision of the organizational documents of the Seller, or (ii) violate,
conflict with, or constitute a default (or an event which, with notice or lapse

repurchase, rights of first offer or rights of first refusal under, or cause the
acceleration of the maturity of any debt or obligation pursuant to, or result in
the creation or imposition of any security interest, lien or other encumbrance
upon any property of the Seller under any agreement or commitment to which it is
a party, or (iii) violate any statute or law or any judgment, decree, order,
regulation or rule of any court or governmental authority, except in the case of
each of clauses (i), (ii) and (iii) where such violations, conflicts, defaults,

hereunder.

prohibit the sale thereof. On each of the Subsequent Closing Dates, CEMEX (or
its nominee or designee) will acquire good and marketable title to the Number of
Shares purchased by it on such date free and clear of all liens and
encumbrances.

5.   Securities Law Matters. The Seller has conducted its offer and

6.   No Registration. The Seller understands and acknowledges (a) that
it must bear the economic risk of its investment in the CPOs and the underlying
A Shares and B Shares (collectively, the "Securities"); (b) that the Securities
have not been registered under the securities laws of any jurisdiction other
than Mexico and are being offered and sold in reliance upon exemptions provided
in applicable securities laws (other than those of Mexico) for transactions not
involving any public offering and, therefore, cannot be resold or transferred
unless they are subsequently registered under applicable securities laws (other
than those of Mexico, as such Mexican registration will be in effect at the time
of delivery of Securities to the Seller) or unless an exemption from such
registration is available; (c) no regulatory authority has made any finding or
determination as to the fairness for investment of the Securities and no
regulatory authority has recommended or endorsed or will recommend or endorse
any such offer or sale; (d) that it is acquiring the Securities for its own

agreement or arrangement other than in compliance with all applicable securities
laws; (f) that CEMEX does not have any obligation or intention to register the
Securities for sale under any securities laws other than under those of Mexico;

require the registration of the Securities under applicable securities laws and
regulations; and (h) the Securities may not be deposited into any unrestricted
depositary receipt facility established or maintained by a depositary bank.

7.   Status of the Seller. The Seller represents and warrants that

and on each Subsequent Closing Date, it was and will be outside the United
States and, at each such time, it was not and will not be a U.S. person (and was
not and will not be purchasing for the account or benefit of a U.S. person)
within the meaning of

affect CEMEX's ability to perform its obligations hereunder.

the Seller's Shares have not been registered under the securities laws of any

and, therefore, cannot be resold or transferred unless they are subsequently

9.   Financial Statements and Disclosures.

(a)  The consolidated historical financial statements of CEMEX
and its consolidated subsidiaries, and the related notes thereto, included in
CEMEX's Annual Report on Form 20-F for the fiscal year ended December 31, 2001
(the "2001 Form 20-F"), as filed by CEMEX with the U.S. Securities and Exchange
Commission (the "SEC"), present fairly in all material respects the consolidated
financial position of CEMEX and its consolidated subsidiaries taken together as
a whole as of the dates indicated and the results of their operations and the
changes in their consolidated cash flows for the periods specified; and said
financial statements have been prepared in conformity with Mexican generally
accepted accounting principles applied on a consistent basis throughout the
periods involved (except as otherwise noted therein).

(b)  As of the date of this Agreement, (i) there has been no
change in the consolidated assets, liabilities or financial condition of CEMEX
from that reflected in the 2001 Form 20-F, except for changes in the ordinary
course of business none of which have, singly or in the aggregate, had a
Material Adverse Effect on CEMEX and its subsidiaries taken as a whole, (ii)
other than general economic or political conditions, since the filing of the
2001 Form 20-F, there has been no event causing a Material Adverse Effect as to
CEMEX and its subsidiaries taken as a whole, nor any development that could,
singly or in the aggregate, reasonably be expected to result in a Material
Adverse Effect as to CEMEX and its subsidiaries taken as a whole, and (iii) the
aggregate number of shares of CEMEX Common Stock issued or issuable pursuant to
the exercise of all warrants, options, subscriptions, purchase rights or
conversion or exchange rights in any convertible securities does not materially
exceed the aggregate number of such shares issued or so issuable as reflected in
the consolidated financial statements of CEMEX included in the 2001 Form 20-F,
except, in the case of clauses (i), (ii) and (iii), as disclosed to the Seller
in writing or otherwise publicly disclosed by CEMEX.

(c)  The 2001 Form 20-F did not, at the time of its filing with
the SEC, contain an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of

483741.01-New York S4A                 22

the circumstances under which they were made when the 2001 Form 20-F was so
filed, not misleading.

10.  Contemporaneous Agreements. Contemporaneously with entering into
this Agreement, CEMEX is entering into separate Stock Purchase Agreements
substantively identical to this Agreement (other than in respect to Article
IV(7) and (11) hereof) with each of AIG Asian Infrastructure Fund II LP, IONA
Investment Pte. Ltd. and Pan Asian Cement Investors, L.P., who together with the
Seller and Orchid Asia II, L.P. constitute, as of the date hereof, all of the
stockholders of CAH that have elected to sell all or any portion of their shares
of common stock of CAH to CEMEX.

11.  No Liquidation of CAH. Until the later of January 2, 2004 or the
date that no further Seller's Shares remain subject to this agreement, CEMEX
shall not effect or permit any liquidation, merger, consolidation or other
organic change in the organization of CAH.

CEMEX at:

Bank: Citibank International, Plc.

Swift: CITIESMX
Company: Cemex Manila Investments B.V.
Account: 0008668019

Notwithstanding the foregoing, the Seller may retain such portion of any
dividend on the Seller's Shares to the extent required to discharge any tax or
withholding expense borne by the Seller and arising from such dividend.

5.   Dividends on CPOs. To the extent that CEMEX makes a dividend or
other distribution in CEMEX Common Stock on the CPOs to be received by the
Seller hereunder, such that the aggregate value (as determined in good faith by
the board of directors of CEMEX (in a manner consistent with any determination
of such value for purposes of Article I(5)) of all dividends or other
distributions made exclusively in CEMEX Common Stock on such CPOs within the 12
months

483741.01-New York S4A                 24

preceding the date of payment of such dividend or distribution (and including
the value of such distribution), and in respect of which no adjustment in the
Number of CPOs pursuant to Article I(5) has been made, exceeds 5% of the
aggregate weighted average price of such CPOs on the Mexican Stock Exchange on
the date such dividend or distribution is declared, then the amount of CEMEX
Common Stock by which such dividends or distributions exceed 5% shall be for the
benefit of the Seller.

6.   Escrow of Seller's Shares. The Seller and CEMEX will execute and
deliver the Escrow Agreement at Closing.

7.   Amended Shareholders Agreement and Charter. CEMEX and the Seller
each will (and to the extent required, CEMEX will cause Cemex Manila Investments
B.V. and CEMEX's other Affiliates that own shares of CAH to) (i) approve and
execute the Amended Shareholders Agreement, and (ii) approve the Amended and
Restated Charter. CEMEX will cause CAH to lodge the Amended and Restated Charter
with the Registrar prior to the first Subsequent Closing Date.

8.   Notice of Developments. Each Party will give prompt written
notice to the other of any material adverse development causing a breach of any
of its own representations, warranties, covenants or agreements contained herein
or in the Escrow Agreement.

9.   General. After the Closing, each of the Parties shall, from time
to time, at the request of the other Party and without further cost or expense
to the Party making the request, execute and deliver (and, if appropriate, file)
or cause to be executed and delivered (and, if appropriate, filed) such other
instruments of conveyance and transfer and other documents reasonably required
to carry out the intent of the Transaction Documents as any other Party may
reasonably request and continue to use reasonable efforts to obtain any
consents, approvals, authorizations and waivers necessary in order to more
effectively consummate the transactions contemplated herein and therein.

10.  Confidentiality. The Seller will treat and hold as such all
Confidential Information (as defined below), refrain from using any Confidential
Information except in connection with this Agreement, and deliver promptly to
CEMEX or destroy, at the request and option of CEMEX, all tangible embodiments
(and all copies) of Confidential Information that are in its possession;
provided, however, that Seller may share such Confidential Information on an as
needed basis with its officers, Affiliates, limited partners and legal and
financial advisers if such officers, Affiliates, limited partners and advisers
are instructed by the Seller to treat

483741.01-New York S4A                 25

and hold as such all Confidential Information. If the Seller is required under
law, regulation or legal process to disclose any Confidential Information, the
Seller may disclose such Confidential Information as is so required to be
disclosed. In the event that the Seller is requested or required to disclose any
Confidential Information, the Seller will notify CEMEX promptly of the request
or requirement. For purposes hereof, "Confidential Information" means any
information received from CEMEX, CAH or any of their respective representatives
or Affiliates concerning the businesses and affairs of CAH that is not already
generally available to the public. In any event, the aforesaid confidential
obligations do not apply to any Confidential Information that is in the public
domain other than as a result of the Seller's breach of undertaking herein, or
in relation to any Confidential Information that has been given to the Seller by
a third party who is not known to the Seller to be in breach of any obligation
of secrecy to CEMEX or to any Confidential Information already in Seller's free
possession at the time of disclosure by CEMEX, CAH or any of their respective
Affiliates.

11.  Ownership of Seller's Shares. For the avoidance of doubt, CEMEX
and the Seller acknowledge and agree that pursuant to Section 4.1(a) of the
Amended Shareholders Agreement, notwithstanding the delivery of the Seller's
Shares to the Escrow Agent as contemplated by the Transaction Documents, the
Seller shall be deemed to "own" the Seller's Shares held by the Escrow Agent for
purposes of Section 4.1(a) of the Amended Shareholders Agreement; provided, that
the Seller shall not be deemed to "own" any Seller's Shares transferred to CEMEX
(or its nominee or designee) on a Subsequent Closing Date.

12.  Subsequent Modification. If at any time or from time to time
after the date hereof and prior to the final Subsequent Closing Date, CEMEX or
any of its Affiliates shall have entered into an agreement or understanding
relating to the acquisition of or other payment in respect to (whether for cash
or other consideration, and whether pursuant to any form of option, call, put,
purchase, redemption, exchange, retirement or other right) shares of common
stock of CAH from a stockholder other than the Seller, and the terms of such
other agreement or understanding are more favorable to such stockholder than the
terms hereof or the Escrow Agreement are to the Seller, then, within thirty (30)
days of the date of such other agreement or understanding, CEMEX shall provide
to Seller a written description of such other agreement or understanding and
provide Seller a period of at least thirty (30) days in which to decide whether
or not to modify the terms hereof or of the Escrow Agreement to reflect the
terms of such other agreement or understanding (including, without limitation, a
change in the amounts used to calculate the Number of CPOs in Article I(2)
hereof).

483741.01-New York S4A                 26

13.  No Other Transfer of Seller's Shares.

(a)  CEMEX hereby consents to the transfer and release of all of
the Seller's Shares held of record by the Trustee under the Investor Trust
Agreement for purposes of the transactions contemplated in this Agreement;
provided, however, that if the sale of all the Seller's Shares to CEMEX
contemplated hereby is not consummated, then the Seller shall promptly redeposit
50% of such unsold Seller's Shares with the Trustee under the Investor Trust
Agreement.

(b)  The Seller agrees that, except as expressly permitted by
this Agreement or the Transaction Documents, it will not (i) sell, assign (by
operation of law or otherwise) or otherwise dispose of, or grant any option with
respect to, any of the Seller's Shares, or (ii) create or suffer to exist any
lien, security interest, option or other charge or encumbrance upon or with

Re:  CEMEX, S.A. de C.V.
Tender Offer for Appreciation Warrants
--------------------------------------

Ladies and Gentlemen:

In connection with the offer by CEMEX, S.A. de C.V. (the "Company") to
purchase for cash (the "Offer"), upon the terms and subject to the conditions
set forth in the Offer to Purchase (as defined below), all of its Appreciation
Warrants ("Appreciation Warrants") and American Depositary Warrants ("ADWs"),
each ADW representing five Appreciation Warrants, that are tendered in the Offer
at or below the Selected Purchase Price (as defined in the Offer to Purchase),
you have requested our opinion regarding certain descriptions of tax
consequences contained in the combined statement on Schedules TO and 13E-3 (the
"Schedule TO"), as filed with the Securities and Exchange Commission (the
"Commission") under cover of Schedule TO on the date hereof under the Securities
Exchange Act of 1934, as amended (the "Exchange Act") (such combined statement
being hereinafter referred to as the "Schedule TO").

This opinion is being furnished in accordance with the requirements of Item
1016(h) of Regulation M-A under the Securities Act of 1933, as amended.

We have acted as special United States federal income tax counsel to the
Company in connection with the Offer.

CEMEX, S.A. de C.V.
November 17, 2003
Page 2

In rendering the opinions set forth herein, we have examined and relied on
originals or copies of the following documents:

(a) the Schedule TO;

(b) the Offer to Purchase, dated November 17, 2003, relating to the
Offer, in the form filed as exhibit (a)(1)(A) to the Schedule TO (the
"Offer to Purchase");

(c) the Warrant Deposit Agreement, dated as of November 26, 2001,
among the Company, Citibank, N.A., as depositary, and the holders and
beneficial owners of ADWs evidenced by American Depositary Warrant Receipts
issued thereunder (the "Deposit Agreement");

(d) the form of the American Depositary Warrant Receipt attached as
Exhibit A to the Deposit Agreement; and

(e) the tax opinion provided by Mexican tax counsel relating to the
Mexican tax consequences of the Offer.

We have also examined originals or copies, certified or otherwise
identified to our satisfaction, of such records of the Company and such
agreements, certificates of public officials, certificates of officers or other
representatives of the Company and others, and such other documents,
certificates and records as we have deemed necessary or appropriate as a basis
for the opinions set forth herein. In addition, we have relied upon statements
and representations made to us by representatives of the Company and others. For
purposes of this opinion, we have assumed the validity and the initial and
continuing accuracy of the facts, information, and analyses set forth in such
documents, certificates, records, statements and representations referred to
above.

In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, conformed, or photostatic copies, and
the authenticity of the originals

CEMEX, S.A. de C.V.
November 17, 2003

of such copies. In making our examination of documents executed, or to be
executed, by the parties indicated therein, we have assumed that each party,
including the Company, is duly organized and existing under the laws of the
applicable jurisdiction of its organization and had, or will have, the power,
corporate or other, to enter into and perform all obligations thereunder, and we
have also assumed the due authorization by all requisite action, corporate or
other, and execution and delivery by each party indicated in the documents and
that such documents constitute, or will constitute, valid and binding
obligations of each party.

In rendering our opinion, we have considered the current provisions of the
Internal Revenue Code of 1986, as amended, Treasury Department regulations
promulgated thereunder, judicial authorities, interpretive rulings of the
Internal Revenue Service, and such other authorities as we have considered
relevant, all of which are subject to change or differing interpretations,
possibly on a retroactive basis. There can be no assurance that the opinion
expressed herein will be accepted by the Internal Revenue Service or, if
challenged, by a court. Moreover, a change in the authorities or the accuracy or
completeness of any of the information, documents, certificates, records,
statements, representations, covenants, or assumptions on which our opinion is
based could affect our conclusions.

Based upon the foregoing and in reliance thereon, we are of the opinion
that the statements set forth in the Offer to Purchase under the caption
"Special Factors - 8. Income Tax Considerations - U.S. Federal Income Tax
Considerations," insofar as such statements purport to summarize Federal laws of
the United States referred to thereunder, fairly summarize such laws.

CEMEX, S.A. de C.V.
November 17, 2003

This opinion is expressed as of the date hereof, and we are under no
obligation to supplement or revise our opinion to reflect any changes (including
changes that have retroactive effect) in applicable law or any information,
document, certificate, record, statement, representation, covenant, or
assumption relied upon herein that becomes incorrect or untrue. Except as set
forth above, we express no opinion to any party as to the tax consequences,
whether United States federal, state, local, or foreign, of the Offer or of any
transaction related to or contemplated by such Offer.

Very truly yours,

TO"), as filed with the Securities and Exchange Commission (the "Commission")
under cover of Schedule TO on the date hereof under the Securities and Exchange
Act of 1934, as amended (the "Exchange Act") (such combined statement being
hereinafter referred to as the "Schedule TO").

This opinion is being furnished in accordance with the requirements of
Item 1016(h) of regulation M-A under the Securities Act of 1933, as amended.

We have acted as special Mexican federal income tax counsel to the
Company in connection with the Offer.

In rendering the opinions set forth herein, I have examined and relied
on originals or copies of the following documents:

(a)  the Schedule TO;

(b)  the Offer to Purchase, dated November 17, 2003, relating to the
Offer, in the form filed as exhibit (a)(l)(A) to the Schedule TO (the
"Offer to Purchase");

(c)  the Warrant Deposit Agreement, dated as of November 26, 2001,
among the Company, Citibank, N.A., as depositary, and the holders and
beneficial owners of ADWs evidenced by American Depositary Warrant Receipts
issued thereunder (the "Deposit Agreement");

(d)  the form of the American Depositary Warrant Receipt attached as
Exhibit A to the Deposit Agreement; and

(e)  the tax opinion provided by United States tax counsel relating to
the United States tax consequences of the Offer.

I have also examined originals or copies, certified or otherwise
identified to my satisfaction, of such records of the Company and such
agreements, certificates of public officials, certificates of officers or other
representatives of the Company and others, and such other documents,
certificates and records as I have deemed necessary or appropriate as a basis
for the opinions set forth herein. In addition, I have relied upon statements
and representations made to me by representatives of the Company and others. For
purposes of this opinion, I have assumed the validity and the initial and
continuing accuracy of the facts, information, and analyses set forth in such
documents, certificates, records, statements and representations referred to
above.

In my examination, I have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to me as originals, the conformity to original documents of all
documents submitted to me as certified, conformed, or photostatic copies, and
the authenticity of the originals of such copies. In making my examination of
documents executed, or to be executed, by the parties indicated therein, I have
assumed that each party, including the Company, is duly organized and existing
under the laws of the applicable jurisdiction of its organization and had, or
will have, the power, corporate or other, to enter into and perform all
obligations thereunder, and I have also

assumed the due authorization by all requisite action, corporate or other, and
execution and delivery by each party indicated in the documents and that such
documents constitute, or will constitute, valid and binding obligations of each
party.

Based upon the foregoing and in reliance thereon, I am of the opinion
that the statements set forth in the Offer to Purchase under the caption
"Special Factors - 8. Income Tax Considerations - Mexican tax Consequences",
insofar as such statements purport to summarize Federal laws of Mexico referred
to thereunder, fairly summarize such laws.

This opinion is expressed as of the date hereof, and I am under no
obligation to supplement or revise my opinion to reflect any changes (including
changes that have retroactive effect) in applicable law or any information,
document, certificate, record, statement, representation, covenant, or
assumption relied upon herein that becomes incorrect or untrue. Except as set
forth above, I express no opinion to any party as to the tax consequences,
whether federal, state, local, or foreign, of the Offer or of any transaction
related to or contemplated by such Offer. I express no opinion as to the laws of
any other jurisdiction other than the tax laws of Mexico to the extent
specifically referred to herein. This opinion is expressed as of the date
hereof, unless otherwise expressly stated, and I disclaim any undertaking to
advise you of any subsequent changes of the facts stated or assumed herein or
any subsequent changes in applicable law.

Very truly yours,
