For each withdrawal the trustee of the TRUST desires to make on the account of the LOAN, [the trustee] shall provide the relevant request to “BANOBRAS” prior to the date it wishes to dispose the LOAN, and such request shall contain the amount to be withdrawn, as determined by “BANOBRAS” consistent with the terms of the preceding paragraph, the name of the banking institution, the account number to which “BANOBRAS” shall deposit the funds so requested, the branch number and location, and the Standardized Banking Code (XXXXX), as applicable. The request shall have been previously approved by the agent or agents of the trustee of the TRUST, provided that such agents shall have properly substantiated their authority. The foregoing shall be a condition for “BANOBRAS” to effect the relevant disbursement. Therefore, “CEMEX” expressly agrees and acknowledges that withdrawals of the LOAN shall have been deemed to have made for the amounts “BANOBRAS” funds to the trustee and into the TRUST, and covenants that the provisions of this clause shall not be contested in the future.

“BANOBRAS” shall be released of any and all liability due to the failure of the trustee to exercise its withdrawal rights on the account of the LOAN.

For the purposes of the foregoing clause, the parties hereto agree to adhere to the following provisions:

Provisions applicable to the TRANCHE “A” [LOAN]:

I. First withdrawal period. “CEMEX”, acting trough the TRUSTEE, shall be entitled to make the first withdrawal on the account of the LOAN, in connection with the TRANCHE “A”, in a period not to exceed thirty calendar days, from and after compliance or satisfaction of the conditions precedent.

If “CEMEX”, acting trough the TRUSTEE, should fail to make the first withdrawal of the TRANCHE “A” within the above referred time period, “BANOBRAS” may extend the same, provided that, “BANOBRAS” receives a written request to that end from “CEMEX”, and [“BANOBRAS”] approves the same with due anticipation prior to the expiration of the relevant period. Notwithstanding the foregoing, “BANOBRAS” hereby reserves the right to cancel any extension so approved, at any time, by means of written notice thereof to “CEMEX”.

The amount to be withdrawn from the TRANCHE “A”, as determined by “BANOBRAS” consistent with the provisions or the third paragraph of this clause, shall be referred to as the TRANCHE “A” AVAILABLE AMOUNT.

II. Subsequent withdrawal periods. “CEMEX”, acting trough the TRUSTEE, shall be entitled to make further withdrawals on the account of the LOAN, pursuant to the following terms:

The parties hereto agree that the period to make withdrawals on the account of the TRANCHE “A” LOAN shall expire upon exhausting the total amount of the LOAN, or else, upon sixty calendar days after the first withdrawal was made, whichever is first.

“BANOBRAS” shall then open a new withdrawal period, each one of no more than sixty calendar days, provided that the TRANCHE “A” AVAILABLE AMOUNT has not been exhausted in the immediately prior withdrawal period. Withdrawals for new periods may be made for up to the balance between the TRANCHE “A” AVAILABLE AMOUNT and the amount disposed as of the new withdrawal date, which implies, to the extent necessary, that “CEMEX” shall be required to increase the payment source pursuant to the standards set forth in this agreement, by means of contribution of collection rights of FUTURE CONTRACTS into the TRUST, and thus maintaining the ratio of two to one of the payment source, considered individually per AGREEMENT or FUTURE CONTRACTS. The foregoing is not and shall not be deemed as a revolving loan and thus, it is not subject to the revolving criteria provided for in the fifth clause below.

Page 17 ..

The last withdrawal period shall take place no later than six months prior to the expiration of the LOAN term and provided that the execution periods of FUTURE CONTRACTS which are to be used as payment source at that time, do not exceed the maximum period of the LOAN. If the relevant construction time periods should exceed the term of the LOAN, the revolving amount shall be adjusted pursuant to the payments expected to receive during the period.

During the term of the LOAN, “CEMEX” shall be entitled to make new withdrawals on the account of the TRANCHE “A” LOAN by resorting to the revolving mechanism, according to the criteria set forth in the fifth clause below.

During each withdrawal period, interest accrued and outstanding may be capitalized, according to the terms set forth in the seventh clause below.

The amount of withdrawals for each withdrawal period shall be recorded in an independent account and thus, until the time the relevant withdrawal period is concluded, the amount so withdrawn shall not be computed in the consolidated balance of this Tranche, for the purposes of computing interest and repayment [of the TRANCHE “A” LOAN].

The balance of the independent account generated for each withdrawal period, including interest capitalized, shall be consolidated into the unpaid balance of this Tranche, on the day that the relevant withdrawal period should expire, thus creating a new unpaid balance of the TRANCHE “A” [LOAN].

The consolidated balance of this TRANCHE “A” and the amounts of the withdrawals generated throughout the relevant withdrawal period shall accrue interest according to the terms set forth in the seventh clause below.

Provisions applicable to the TRANCHE “B” [LOAN]:

I. Subsequent withdrawal periods. “CEMEX”, acting trough the TRUSTEE, shall be entitled to make further withdrawals on the account of the TRANCHE “B” [LOAN], pursuant to the following terms:

Until the time period which is fifty-four months computed as of the first withdrawal of the LOAN, and with such frequency as the GDF (in respect to the GDF CERTIFICATES), and the governmental agencies or third private parties (in respect to the FUTURE CONTRACTS), should issue PAYMENTS DOCUMENTS.

The amount to be disbursed for each of the GDF CERTIFICATES, and/or the PAYMENT DOCUMENTS, shall be for up to eighty percent of the amount each should represent.

The last withdrawal period on the account of the TRANCHE “B” [LOAN], shall take place no later than six months prior to the expiration of the LOAN term and provided that the execution periods of FUTURE CONTRACTS which are to be used as payment source at that time, do not exceed the maximum period of the LOAN. If the relevant construction time periods should exceed the term of the LOAN, the revolving amount shall be adjusted pursuant to the payments expected to receive during the period.

FIFTH. REVOLVING [NATURE OF THE LOAN]. The LOAN extended under the terms of this agreement is granted on a revolving basis. Payment in full of the principal and the relevant interest for any withdrawal period made by “CEMEX”, shall replenish the available amount of the LOAN, in such amount as determined by “BANOBRAS”, consistent with the following criteria:

For the TRANCHE “A” [LOAN] and during the term of the LOAN, one or more revolving [withdrawals] may be exercised, provided, however, that not less than fifty percent of the outstanding balance of the LOAN in connection with the immediately prior withdrawal period has been repaid, and therefore, the amount of the new available withdrawal shall be determined based upon the sufficiency of the payment source, a situation to be notified by “BANOBRAS” to the TRUST, with copy served onto “CEMEX”. To the extent necessary, the latter may be increased by means of contribution made by “CEMEX”, of its right and interest to the collection rights into the TRUST, in connection with FUTURE CONTRACTS, in order to comply with the above referred ratio condition of two to one between the LOAN and the payment source, for which, as provided for in the third paragraph of the fourth clause above, the amount available of the LOAN shall be notified by “BANOBRAS” to the trustee of the TRUST, with copy served to “CEMEX”.

The TRANCHE “B” [LOAN] shall be revolving under the terms of the provisions set forth in the first paragraph of this clause.

SIXTH.

II. A withdrawal fee equal to zero point twenty-five per cent.

This commission fee shall apply to additional withdrawals made in exercise of the revolving [nature] of the TRANCHE “B” of the LOAN referred to in the fifth clause above.

All commission fees referred to in this clause shall accrue VAT.

“CEMEX” hereby irrevocably instructs “BANOBRAS” to pay the above referred commission fees from the proceeds of the LOAN, on the dates such commissions should become payable, and to this end, “BANOBRAS” is hereby authorized to make the relevant accounting entries.

To that end, “CEMEX” expressly agrees and acknowledges that all withdrawals made on the account of the LOAN as per the terms noted above, shall be deemed made for the relevant amounts and that in virtue of the foregoing, the provisions of this clause shall not be contested in the future.

SEVENTH. INTEREST. “CEMEX” shall pay “BANOBRAS”, on a monthly basis, consistent with the procedure laid down in the following clause, as of the date of the first withdrawal of the LOAN is made, and until it is repaid in full, interest at a rate resulting from adding TIIE quoted at 28 (twenty-eight) days, the following margins:

To the TRANCHE “A”: four percentage points; and

To the TRANCHE “B”: three percentage points.

For the purposes of this clause, the following definitions shall apply:

Interest Period. [Shall mean] the period to determine interest accruing upon the outstanding balance of the LOAN, which is to commence the day in which the first withdrawal of the LOAN is made, and which shall conclude the same day of the next month. Subsequent interest periods shall commence and conclude pursuant to the same procedure, in other words, they shall commence the same day on which the immediately prior period ends, and shall conclude the same day of the next month.

Notwithstanding the above, there shall be irregular interest periods in the calculation of interest whenever: i) a withdrawal of the LOAN is made on a date which is not an interest payment date, [in which case] accrued interest shall be calculated according to the actual number of days elapsed between the date in which the relevant withdrawal is made and the date in which the next interest payment period expires; ii) governmental agencies and/or private entities deposit funds into the TRUST on a date which is not an interest payment date, [in which case] interest accrued shall be calculated according to the actual number of days elapsed between the date in which the relevant withdrawal is made and the date in which “BANOBRAS” should provide written notice to the trustee of the TRUST, as to the amount payable on the account of interest and principal and then payment by the trustee of the TRUST is made accordingly.

Subsequent withdrawals on the account of each of the Tranches of the LOAN shall be incorporated into the outstanding balance of each Tranche, and thus, the INTEREST PERIOD on the account of such withdrawals shall be adjusted at the closing of the withdrawal period of the first withdrawal of each Tranche.

Except as provided above, payment of interests regarding each period shall be made precisely the day in which the relevant period should conclude.

Whenever an interest period should conclude on a day which is not a banking business, payment shall be extended to the immediately following business banking day, and the relevant extension shall be considered to compute the relevant interest.

TIIE. As to a relevant interest period, [shall mean] the Interbanking Balance Interest Rate (Tasa de Interes Interbancaria de Equilibrio) quoted at 28 (twenty-eight) days, as announced by the Banco de Mexico in the Federal Official Gazette, as is in force one business day prior to the commencement of each INTEREST PERIOD. The TIIE shall be reviewed on a monthly basis.

If the above rate should be modified or otherwise ceases to exist, the relevant calculation shall be made according with the rate or rates that should replace it, and in the absence of any rate, according with such rate as determined by the Ministry of Finance (Secretaria de Hacienda y Credito Publico) from time to time.

BUSINESS BANKING DAY. [Shall mean] the days on which Mexican banking institutions are not authorized to close operations to the general public, and cease business pursuant to the resolutions issued by the National Banking and Securities Commission (Comision Nacional Bancaria de Valores).

Interest rate shall be expressed annually and shall be calculated dividing the applicable interest rate between three hundred and sixty days, and the result obtained multiplied by the actual number of days elapsed during the period in which interest accrue with the applicable interest rate, and the result thereof shall be applied to the outstanding balance of the LOAN.

Upon the default of “CEMEX” to repay the LOAN as it becomes due consistent with the terms of the following clause, “CEMEX” shall pay “BANOBRAS” late interest at a rate equal to the regular interest rate referred to in this clause as it may be in force on the date payment was due, times one point five. Late interest shall be computed over the outstanding balance of the LOAN, and determined on a quarterly basis or fraction thereof, as of the date the same became due until repayment in full.

All payments of interest to be made by “CEMEX” to the trustee of the TRUST, for the benefit of “BANOBRAS”, shall be made on their relevant due dates as provided for in the tenth clause below, without the need of prior demand from “BANOBRAS”.

The parties hereto agree that during the withdrawal period of the TRANCHE “A” of the LOAN, accrued and outstanding interest may be capitalized according to the terms of article three hundred and sixty three of the Commerce Code.

The determination of interest shall be notified one business day prior to the date they become due.

“CEMEX” agrees to contribute funds into the TRUST as it may be necessary to pay interest on the specified dates.

EIGHTH.- REPAYMENT. “CEMEX”, acting to the trustee of the TRUST, agrees to repay the outstanding balance of the LOAN to “BANOBRAS”, together with interest referred to in the preceding clause, according to the following procedure:

Repayment of the TRANCHE “A” LOAN.

Upon expiration of the withdrawal period on the account of the TRANCHE “A” LOAN, repayments on the account of the LOAN shall be made on each occasion the trustee of the TRUST should receive payments on the account of the GDF CERTIFICATES and/or the PAYMENT DOCUMENTS, excluding VAT, and deducting the portion of the down payment tendered and thus, repayment of the LOAN, as to the TRANCHE “A”, shall be completed with payment of the last GDF CERTIFICATE and/or PAYMENT DOCUMENT.

Notwithstanding the above, “CEMEX” hereby agrees that if payment has not been received in full on the account of the GDF CERTIFICATES and/or the PAYMENT DOCUMENTS within a period of FIVE MONTHS following completion of the relevant construction works contemplated in the CONTRACTS and the FUTURE CONTRACTS, “CEMEX” agrees to repay the outstanding balance of the LOAN with independent funds to be contributed to the TRUST corpus, unless:

i) There should be a document in writing substantiating the extension of the term to complete the construction works subject matter of the CONTRACTS and/or the FUTURE CONTRACTS, as issued by the relevant contracting governmental agency or private corporate entity; or

ii) There should be additional payment sources ensuing from FUTURE CONTRACTS, the collection interest of which have been previously contributed into the TRUST corpus and are enough to repay “BANOBRAS” the amount of the LOAN, or

iii) The CONTRACTS and/or FUTURE CONTRACTS should provide for payment schedules which exceed the construction schedule of the work.

A quotient shall be determined each time a withdrawal period has expired (a repayment quotient is equal to the result of dividing the consolidated balance of the TRANCHE “A” LOAN between the amount represented by the construction work pending completion the payment of which is outstanding from the contracting governmental agencies or private corporate entities, under the terms of the CONTRACTS and/or FUTURE CONTRACTS, deducting any down payments and excluding the relevant VAT), to be applied to the balance of the TRANCHE “A” LOAN, according to the following formula:

FAt= St / OPEt (Fat equals St divided into OPEt)

Where:

Fat= Repayment quotient during the period “t”.

St= Consolidated balance of the TRANCHE “A” LOAN at the end of each withdrawal period during the period “t”.

OPEt= Amount of the construction work pending completion and amount of the work pending payment from the contracting governmental agencies or private corporate entities, under the terms of the CONTRACTS and/or FUTURE CONTRACTS, deducting any down payments, and excluding VAT, during the period “t”.

“CEMEX” acknowledges that repayment of the LOAN is to be made through the trustee of the TRUST, and that repayment is not to be suspended or interrupted, and that repayments of principal to be made through such trustee shall be made on their relevant due dates, according to the terms of this instrument.

To determine the amount of each installment of repayment “CEMEX” is required to make to “BANOBRAS”, prior written notice made by the trustee of the TRUST to “BANOBRAS” as to the amounts of each of the GDF CERTIFICATES and/or the PAYMENT DOCUMENTS received, the quotient (Fat) referred to in the preceding paragraph, shall be multiplied by each of the GDF CERTIFICATES and/or the PAYMENT DOCUMENTS which may have been paid, consistent with the following formula:

Amt= (Fat X MEt)

Non-Official Translation.

Revolving Loan Agreement.

Public instrument number 116,380.

Page 22 ..

Where:

Amt= Amount of the repayment installment during the period “t”.

Fat= Repayment quotient during the period “t”.

MEt= Amount of GDF CERTIFICATES and/or the PAYMENT DOCUMENTS paid, exclusive of VAT, during the period “t” deducting any relevant down payments.

Upon making the calculation of the amount of the repayment installment, “BANOBRAS” shall provide written notice to the trustee of the TRUST, with copy served to “CEMEX”, the amount of each repayment installment.

“CEMEX”, acting through the trustee of the TRUST, shall tender the relevant repayment on the next business day following [receipt] of the notice referred in the immediately above paragraph.

If at any time during any withdrawal period the TRUST should receive funding on the account of payment of the GDF CERTIFICATES and/or the PAYMENT DOCUMENTS, then the amount of the repayment installment shall be applied to the balance of the consolidated account of the TRANCHE “A” only.

If the value of the collection interest on the account of the CONTRACTS and the FUTURE CONTRACTS should vary for any reason, then “BANOBRAS” may adjust the repayment quotient (FAt) accordingly.

“CEMEX” hereby agrees that upon the event of a rescission or early termination of the CONTRACTS and the FUTURE CONTRACTS, the settlement amount tendered by the relevant contracting governmental agency or private corporate entity, shall be allocated, to its fullest extent, to repay the outstanding balance of the LOAN on record as of such date.

Repayment of the TRANCHE “B” LOAN.

Installments of repayment shall be made on each occasion the trustee of the TRUST should receive payments ensuing from the GDF CERTIFICATES and/or the PAYMENT DOCUMENTS, and these proceeds shall be applied until the outstanding balance of the TRANCHE “B” LOAN has been repaid in full relating to each of said documents.

NINTH. SOURCE OF PAYMENT. The following shall be deemed the source of payment of the LOAN:

I. One hundred percent of [“CEMEX’s”] right and interest to the collection of the CONTRACTS, to the extent not committed and not withdrawn as of the date of execution hereof and/or their contribution thereof to the TRUST.

II. One hundred percent of [“CEMEX’s”] right and interest to the collection of the FUTURE CONTRACTS, to the extent not committed and not withdrawn as of their contribution thereof to the TRUST.

III. Other income of “CEMEX” to:

3. In the event the relevant contracting governmental agencies or private corporate entities should pay funds on the account of the CONTRACTS and the FUTURE CONTRACTS, in a [bank] account other than the TRUST account, the parties hereto agree that “CEMEX” shall immediately contribute into the TRUST corpus such funds as it may be required to pay the items stated in the above numerals 1, 2 and 3 (sic) above, in the event there should be a deficiency in the TRUST corpus or whenever the relevant contracting governmental agencies or private corporate entities have made a payment in a [bank] account other than the TRUST account.

For collection rights and interests into the FUTURE AGREEMENTS to qualify as source of payment of the LOAN, “CEMEX” shall be required to previously comply, to the satisfaction of “BANOBRAS”, the following conditions:

A) To contribute into the TRUST corpus one hundred percent of its right and interest to the collection rights of the FUTURE CONTRACTS, to the extent not committed and not withdrawn as of their contribution thereof to the TRUST, provided that [“CEMEX”] shall be required to deliver to “BANOBRAS” copies of the following:

2. Copy of the official letter signed by the authorized agent of “CEMEX”, notifying the relevant contracting governmental agencies or private corporate entities, as applicable, as to the contribution of the collections rights from the FUTURE CONTRACTS into the TRUST.
