Ladies and Gentlemen:

CEMEX, S.A.B. de C.V., a sociedad anónima bursátil de capital variable organized under the laws of Mexico (the “Company”), proposes to sell to the several underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), an aggregate of 975,000,000 Ordinary Participation Certificates of the Company (certificados de participación ordinarios, or “CPOs”) (each CPO representing two Series A Shares (the “Series A Shares”) and one Series B Share (the “Series B Shares”), each without par value, of the Company’s common stock), directly or in the form of American Depositary Shares (“ADSs”), each ADS representing ten CPOs (collectively, the “Underwritten Shares”). In addition, the Company proposes to grant to the Underwriters an option to purchase up to an additional 146,250,000 CPOs, directly or in the form of ADSs (collectively, the “Option Shares”). The Underwritten Shares and the Option Shares are referred to herein as the “Shares.”

The parties hereto agree that 446,250,000 of the Underwritten Shares are outstanding CPOs (the “Selling Subsidiary Shares”) held and to be sold hereunder by certain wholly-owned subsidiaries of the Company listed on Schedule 2 hereto (the “Selling Subsidiaries”).

The ADSs will be issued by the ADS Depositary (as defined below) pursuant to the Second Amended and Restated Deposit Agreement (the “ADS Deposit Agreement”), dated as of August 10, 1999, as amended by Amendment No. 1 thereto dated July 1, 2005, among the Company, Citibank, N.A., as depositary (the “ADS Depositary”), and holders and beneficial owners from time to time of ADSs evidenced by American Depositary Receipts (“ADRs”) issued by the ADS Depositary thereunder.

The CPOs have been or will be issued by the CPO Trustee (as defined below) under the terms of the Fideicomiso No. 111033-9, dated September 6, 1999, as amended (the “CPO Trust Agreement”), entered into between the Company and Banco Nacional de México, S.A., integrante del Grupo Financiero Banamex, as trustee (the “CPO Trustee”), and other than the Selling Subsidiary Shares, pursuant to an Acta de Emisión dated September 7, 1999 in the case of the Selling Subsidiary Shares and a Segunda Acta de Emisión dated September September 7, 2009 in the case of the other Shares (together, the “CPO Deeds”), executed by the CPO Trustee with the acknowledgment and approval of the Mexican Comisión Nacional Bancaria y de Valores (the “CNBV”) and after obtaining an independent appraisal from Nacional Financiera, S.N.C.

The Company and the Selling Subsidiaries are concurrently entering into a Contrato de Colocación (the “Mexican Underwriting Agreement”), dated the date hereof, providing for the sale by the Company to the Mexican underwriters identified therein (the “Mexican Underwriters”) of an aggregate of 325,000,000 CPOs (the “Mexican Firm CPOs”) and providing for the grant to the Mexican Underwriters, acting for this purpose through X.X. Xxxxxx Casa de Bolsa, S.A. de C.V., X.X. Xxxxxx Grupo Financiero, of an option to purchase from the Company up to 48,750,000 additional CPOs (the “Mexican Option CPOs”). In addition, each of the Mexican Underwriters is entering into one or several contratos de sindicación, dated the date hereof, with each of the Mexican xxxxx de bolsa that are part of the Mexican underwriting syndicate. The Mexican Firm CPOs and the Mexican Option CPOs are referred to herein as the “Mexican CPOs.” The Mexican CPOs will be offered and sold in Mexico (the “Mexican Offering”) only pursuant to a Spanish-language prospectus (the “Mexican Prospectus”), which will be substantially similar, with respect to information disclosed, to the Prospectus (as defined below), with such differences as are appropriate to reflect Mexican law and market practices. The offering contemplated by this Agreement and the Mexican Offering are referred to herein as the “Global Offering.”

The Underwriters and the Mexican Underwriters have entered into an Intersyndicate Agreement, dated the date hereof, which provides for, among other things, reallocation, responsibility for stabilization activities and offering restrictions.

The Company and the Selling Subsidiaries hereby confirm their agreement with the several Underwriters concerning the purchase and sale of the Shares, as follows:

The Company has prepared and filed with the U.S. Securities and Exchange Commission (the “SEC”) under the U.S. Securities Act of 1933, as amended, and the rules and regulations of the SEC thereunder (collectively, the “Securities Act”) an “automatic shelf registration statement” (as defined pursuant to Rule 405 under the Securities Act) on Form F-3 (File No. 333-161787) relating to the Shares. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; the prospectus filed as part of the Registration Statement is referred to herein as “Base Prospectus”; the Base Prospectus, as supplemented by the preliminary prospectus supplement related to the Shares, as filed with the SEC pursuant to Rule 424(a) under the Securities Act, which omits Rule 430 Information, is referred to herein as the “Preliminary Prospectus”; and the Base Prospectus, as supplemented by the final prospectus supplement related to the Shares, as filed with the SEC pursuant to Rule 424(a) under the Securities Act, in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with the confirmation of sales of the Shares, is referred to herein as the “Prospectus.” Any reference in this Agreement to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 6 of Form F-3 under the

Securities Act, as of the effective date of the Registration Statement or the date of the Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the U.S. Securities Exchange Act of 1934, as amended, and the rules and regulations of the SEC thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein.

At or prior to the Applicable Time (as defined below), the Company had prepared the following information (collectively with the pricing information set forth on Annex A hereto, the “Pricing Disclosure Package”): the Preliminary Prospectus dated September 8, 2009 and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

2. Purchase of the Shares by the Underwriters.

(a) The Company and the Selling Subsidiaries agree, severally and jointly, to sell the Underwritten Shares to the several Underwriters as provided in Schedule 2 hereto, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company and the Selling Subsidiaries the respective number of Underwritten Shares set forth opposite such Underwriter’s name in Schedule 1 hereto at a price per CPO of MXP 15.90 and per ADS of U.S.$ 11.93750.

In addition, the Company agrees to sell the Option Shares to the several Underwriters as provided in Schedule 2 hereto, and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Company the Option Shares at the purchase price set forth in the preceding paragraph, less an amount per Option Share, as the case may be, equal to any dividends or distributions declared by the Company and payable on the Underwritten Shares but not payable on the Option Shares.

If any Option Shares are to be purchased, the number of Option Shares to be purchased by each Underwriter shall be the number of Option Shares which bears the same ratio to the aggregate number of Option Shares being purchased as the number of Underwritten Shares set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 10 hereof) bears to the aggregate number of Underwritten Shares being purchased from the Company and the Selling Subsidiaries by the several Underwriters, subject, however, to such adjustments to eliminate any fractional Shares as the Representatives in their sole discretion shall make.

The Underwriters may exercise the option to purchase Option Shares for the sole purpose of covering sales of Shares in excess of the number of Underwritten Shares; it being understood that such option shall be exercised in a coordinated manner with, but may be exercised separately from, the option under the Mexican Underwriting Agreement to purchase Mexican Option CPOs. The Underwriters may exercise such option at any time in whole, or from time to time in part, on or before the thirtieth day following the date hereof, by written notice from the Representatives to the Company. Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised and the date and time when the Option Shares are to be delivered and paid for, which may be the same date and time as the Closing Date (as hereinafter defined) but shall not be earlier than the Closing Date or later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10 hereof). Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

(b) The Underwriters may elect to have ADSs, in lieu of CPOs, delivered and paid for under this Agreement. The Representatives on behalf of the Underwriters shall notify the Company, not less than two full business days prior to the Closing Date or the Additional Closing Date (as defined hereinafter), as the case may be, of the portion of Shares to be delivered in the form of ADSs. The Company and the Selling Subsidiaries shall deposit the CPOs underlying such Shares with the Mexican custodian for the ADS Depositary in accordance with the provisions of the ADS Deposit Agreement against the issuance of ADSs.

(c) The Company understands that the Underwriters intend to make a public offering of the Shares as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Shares outside of Mexico on the terms set forth in the Prospectus. The Company acknowledges and agrees that the Underwriters may offer and sell Shares to or through any broker-dealer affiliate of an Underwriter.

(d) Payment for the Shares shall be made by wire transfer in immediately available funds, in the case of Shares purchased in the form of ADSs hereunder, in U.S. dollars to the U.S. dollar account in New York City and, in the case of Shares purchased in the form of CPOs hereunder, in Mexican pesos to the Mexican peso account in Mexico, in each case specified by the Company and the Selling Subsidiaries to the Representatives, in the case of the Underwritten Shares, at 10:00 A.M., New York City time, on September 28, 2009, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing or, in the case of the Option Shares, on the date and at the time specified by the Representatives in the written notice of the Underwriters’ election to purchase such Option Shares, or at such other time and date as the Representatives and the Company may agree upon in writing. The date of such payment for the Underwritten Shares is referred to herein as the “Closing Date,” and the date for such payment for the Option Shares, if other than the Closing Date, is herein referred to as the “Additional Closing Date.”

Payment for the Shares to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made against delivery to the Representatives for the respective accounts of the several Underwriters of the Shares to be purchased on such date in definitive form registered in such names and in such denominations as the Representatives shall request in writing not later than two full business days prior to the Closing Date or the Additional Closing Date, as the case may be, with transfer taxes, if any, payable in connection with the sale of such Shares duly paid by the Company. Delivery of the ADSs shall be made through the facilities of The Depository Trust Company (“DTC”) unless the Representatives shall otherwise instruct. Delivery of the CPOs shall be made through the facilities of S.D. Indeval, Institución para el Depósito de Valores, S.A. de C.V. (“Indeval”) to the accounts of Mexican custodians maintained at Indeval as so requested by the Representatives. The forms of ADRs and CPOs will be made available for inspection by the Representatives at the offices of Xxxxxxx Xxxxxxx & Xxxxxxxx LLP not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date or the Additional Closing Date, as the case may be.

(e) The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Shares contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, neither the Representatives nor any other Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable and documented legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment or supplement thereto) or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, (ii) or any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information furnished to the Company in writing by any Underwriter through the Representatives expressly for use therein (it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below).

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its affiliates, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in

reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or any Pricing Disclosure Package (or any amendment or supplement thereto); it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the names of the underwriters set forth in the table under the second paragraph, the third, ninth, sixteenth and seventeenth paragraphs under the caption “Underwriting.”

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by X.X. Xxxxxx Securities Inc., in consultation with the other Representatives, and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought

hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Subsidiaries, on the one hand, and the Underwriters on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on the one hand, and the Underwriters on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Subsidiaries, on the one hand, and the Underwriters on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company and the Selling Subsidiaries from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Shares. The relative fault of the Company, on the one hand, and the Underwriters on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Shares, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange or the Mexican Stock Exchange; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by U.S. federal, New York State or Mexican authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States or Mexico, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

10. Defaulting Underwriter.

(a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Shares on the Additional Closing Date shall terminate without liability on the

part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses. Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated (including, without limitation, if (i) this Agreement is terminated pursuant to Section 9 hereof, (ii) the Company for any reason fails to tender the Shares for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Shares for any reason permitted under this Agreement), the Company will pay or cause to be paid (a) all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Shares and any taxes payable in connection therewith; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, any Issuer Free Writing Prospectus, any Pricing Disclosure Package and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees, disbursements and expenses of the Company’s counsel and independent accountants in connection with the offering and sale of the Shares; (v) the reasonable and documented fees and expenses incurred in connection with the registration or qualification of the Shares under the state or foreign securities or blue sky laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related reasonable and documented fees and expenses of counsel for the Underwriters); (vi) the costs and charges of any transfer agent, registrar, CPO trustee and depositary; (vii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the U.S. Financial Industry Regulatory Authority (FINRA); (viii) all reasonable and documented out-of-pocket costs and expenses (including, without limitation, reasonable and documented fees, disbursements and other charges of legal counsels and other experts; provided that the aggregate fees of such legal counsels retained by the Underwriters that are subject to reimbursement are approved by the Company in advance of their being retained) incurred by the Underwriters in connection with the transactions contemplated hereby; and (ix) all reasonable and documented expenses incurred by the Company and the Underwriters in connection with any “road show” presentation to potential investors.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective affiliates, successors and the officers and directors and any controlling persons referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Shares from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Shares and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “significant subsidiary” has the meaning set forth in Rule 1-02 of Regulation S-X under the Exchange Act.

15. Miscellaneous.

(a) Authority of the Representatives. Any action by the Underwriters hereunder may be taken by the Representatives on behalf of the Underwriters, and any such action taken by the Representatives shall be binding upon the Underwriters.

(b) Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication. Notices to the Underwriters shall be given to the Representatives c/o X.X.

(c) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

(d) Currency. Each reference in this Agreement to dollars, U.S. dollars or U.S.$ (the “relevant currency”) is of the essence. To the fullest extent permitted by law, the obligations of the Company and the Selling Subsidiaries and in respect of any amount due under this Agreement will, notwithstanding any payment in any other currency (whether pursuant to a judgment or otherwise), be discharged only to the extent of the amount in the relevant currency that the party entitled to receive such payment may, in accordance with its normal procedures, purchase with the sum paid in such other currency (after any premium and costs of exchange) on the business day immediately following the day on which such party receives such payment. If the amount in the relevant currency that may be so purchased for any reason falls short of the amount originally due, the Company and the Selling Subsidiaries will pay such additional amounts, in the relevant currency, as may be necessary to compensate for the shortfall. Any obligation of the Company and the Selling Subsidiaries not discharged by such payment will, to the fullest extent permitted by applicable law, be due as a separate and independent obligation and, until discharged as provided herein, will continue in full force and effect.

(e) Additional Amounts. Each payment of fees or other amounts due to the Underwriters under this Agreement shall, except as required by applicable law, be made without withholding or deduction for or on account of any taxes imposed by any jurisdiction. If any taxes are required to be withheld or deducted from any such payment, the Company and the Selling Subsidiaries shall pay such additional amounts as may be necessary to ensure that the net amount actually received by the Underwriters after such withholding or deduction is equal to the amount that the Underwriter would have received had no such withholding or deduction been required.

(f) Waiver of Immunity. To the extent that the Company or any of its subsidiaries (including the Selling Subsidiaries) has or hereafter may acquire any immunity (sovereign or otherwise) from any legal action, suit or proceeding, from jurisdiction of any court or from set-off or any legal process (whether service or notice, attachment in aid or otherwise) with respect to itself or any of its property, each of the Company and its subsidiaries (including the Selling Subsidiaries) hereby irrevocably waives and agrees not to plead or claim such immunity in respect of its obligations under this Agreement.

(g) Jurisdiction and Venue. Each of the parties hereto hereby irrevocably agrees that any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any U.S. Federal or State court located in the State of New York, County of New York (“New York Court”) and the competent courts located in its jurisdiction of domicile with respect to actions brought against it as defendant, irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such proceeding, and waives any right to which it may be entitled on account of place of residence or domicile, and irrevocably submits to the jurisdiction of such courts in any suit, action or proceeding. Each of the Company and the Selling Subsidiaries has appointed Corporate Creations Network Inc. as its authorized agent (the “Authorized Agent” upon whom process may be served in any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated herein which may be instituted in any New York Court, by any Underwriter, the directors, officers, employees and agents of any Underwriter, or by any person who controls any Underwriter, and expressly accepts the jurisdiction of any such court in respect of any such suit, action or proceeding. Each of the Company and the Selling Subsidiaries hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and each of the Company and the Selling Subsidiaries agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company and the Selling Subsidiaries. The provisions of this Section 15(g) shall survive the termination of this Underwriting Agreement, in whole or in part.

(h) Counterparts. This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

(i) Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

(j) Headings. The headings herein are included for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

Re: CEMEX, S.A.B. DE C.V.

Ladies and Gentlemen:

The undersigned understands that you, as Representatives of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with CEMEX, S.A.B. de C.V., a sociedad anónima bursátil de capital variable organized under the laws of Mexico (the “Company”), providing for the international offering outside of Mexico (the “International Offering”) by the several Underwriters named in Schedule 1 to the Underwriting Agreement, of Ordinary Participation Certificates of the Company (certificados de participación ordinarios, or “CPOs”) (each representing two Series A Shares (the “Series A Shares”) and one Series B Shares (the “Series B Shares”), each without par value, of the Company’s common stock), directly or in the form of American Depositary Shares (“ADSs”), each representing ten CPOs (collectively, the “Shares”).
