 Reference is made to the Irrevocable Security Trust Agreement in Respect of Stock No. F/111388-5, dated September 3, 2009, as amended from time to time (the “Agreement”), entered
into among CEMEX, S.A.B. de C.V. (“CEMEX SAB”), Empresas Tolteca de México, S.A. de C.V. (“Tolteca”), Impra Café, S.A. de C.V. (“Impra Café”), Interamerican Investments, Inc.
(“Interamerican”), CEMEX México, S.A. de C.V. (“CEMEX México”), and Centro Distribuidor de Cemento, S.A. de C.V. (“Cedice”), as settlors (CEMEX SAB, Tolteca, Impra Café,
Interamerican, CEMEX México and Cedice, together, the “Settlors”); CEMEX México, Cedice, Mexcement Holdings, S.A. de C.V. (“Mexcement”) and Corporación Gouda, S.A. de C.V.
(“Gouda”), as issuers (CEMEX México, Cedice, Mexcement and Gouda, together, the “Issuers”); Banco Nacional de México, S.A., Integrante del Grupo Financiero Banamex, División Fiduciaria, in its
capacity as trustee (the “Trustee”); and Wilmington Trust (London) Limited, on its own behalf and in its capacity as Security Agent, for the benefit of the Participating Creditors, the Refinancing Creditors (and their respective
successors and assigns) and the other Secured Parties (the “Beneficiary”). Unless otherwise defined herein, capitalized terms defined in the Agreement, are used herein as therein defined. 

On January 11, 2011, CEMEX, S.A.B. de C.V. issued U.S.$ 1,000,000,000 of 9.000% senior secured notes due 2018, guaranteed by CEMEX
México, CEMEX España, S.A. and New Sunward Holding B.V. (together, the “Additional Notes”). Because the purpose of the Additional Notes is to refinance existing indebtedness and, as a consequence thereof, the
Additional Notes will be part of the Refinancing Debt and the holders of the Additional Notes will be a Refinancing Party, in both cases pursuant to the Agreement, by means of this letter the Settlors and the Issuers hereby inform the Trustee and
the Beneficiary, and confirm, that the Additional Notes are secured in accordance with the terms provided in the Agreement, and are part of the Secured Obligations and the holders of the Additional Notes are Secured Parties.
