CEMEX S.A.B. de C.V. (NYSE: CX) announced today that it has received support from 50.34% of the shares of Rinker Group Limited ("Rinker") (ASX: RIN, NYSE ADR: RIN) under its Offer to acquire Rinker shares. As a result, CEMEX has declared its Offer for Rinker to be unconditional and will process acceptances for payment in accordance with the Offer.

Lorenzo H. Zambrano, Chairman of the Board and CEO of CEMEX said: "We are pleased with the support we have received from the Rinker shareholders who to date have accepted our Offer. We are looking forward to the integration of Rinker, which will create one of the world's largest building materials companies."

CEMEX encourages remaining Rinker shareholders to accept the Offer before the scheduled closing date of June 22, 2007 (Sydney time). The Rinker Board has unanimously recommended the Offer and will accept the Offer for their own shares. There is no reason to delay acceptance as the Offer is now unconditional and the Offer Price of US$15.85 has been declared final and cannot be increased. ¹

With majority ownership now achieved, CEMEX will take control of Rinker in due course. Shareholders who do not accept the Offer will become minority holders in Rinker.

CEMEX has proposed that a formal handover occur during the week commencing June 18, 2007. Rinker has confirmed that, as part of that handover and at the request of CEMEX, all Rinker directors will retire from the board in favor of CEMEX's nominees. CEMEX intends to nominate the following persons for appointment to the Rinker board: Mr. Hector Medina (Executive Vice President of Planning and Finance, CEMEX), Mr. Juan Pablo San Agustin (Senior Vice President of Corporate Strategic Planning, CEMEX), Mr. Ramiro Villarreal (General Counsel and Secretary of the Board, CEMEX) and Mr. Stephen Walker. CEMEX has also engaged an independent executive search firm to assist in identifying an additional director.

Acceptances

CEMEX has acceptances in respect of 314,255,971 of Rinker shares, and is in the course of processing acceptances for a further 136,292,399 Rinker shares tendered in accordance with the terms of the Institutional Acceptance Facility described in the Fifth Supplementary Bidder's Statement. This represents 50.34% of Rinker shares in total.

Termination of withdrawal rights

As the Offer has become unconditional, the withdrawal rights which arise under Rule 14d-7 and Section 14(d)(5) of the Securities Exchange Act of 1934 in relation to acceptances of the Offer (as described in Section 7.3 of the Bidder's Statement) are terminated with immediate effect.

Offer closing date

CEMEX notes that the Offer is scheduled to close at 7:00 P.M. (Sydney time) / 5:00 A.M. (New York time) on Friday, June 22, 2007. CEMEX might decide to further extend the offer as contemplated by the Corporations Act.
