CEMEX, S.A.B. de C.V. (NYSE: CX), believes that the target's statement released last week by Rinker Group Limited ("Rinker") (ASX: RIN, NYSE ADR: RIN) does not provide substantial factual information justifying how Rinker would deliver more value to its shareholders than CEMEX's proposal.

On October 27th 2006, CEMEX announced a takeover Offer of US$13.00 per Rinker share at a premium of 27 per cent at that time. CEMEX urges Rinker's shareholders to consider the following facts about Rinker's target's statement:

• The target's statement does not adequately explain Rinker's medium term outlook in the context of slowing end-use markets, particularly in Florida, where the housing bubble is now bursting;
• The target's statement does not outline a viable strategy to grow the business, does not address how Rinker will remedy its capital structure and does not explain why Rinker recently reduced earnings guidance to the low end of its range;
• The "independent expert's" value estimate implies unrealistic multiples and unjustified premiums; and
• The "independent expert" admits its value estimate is based on assumptions that are "difficult to predict with any degree of reliability" and that its conclusions may therefore be unreliable.

CEMEX continues to believe that its US$13.00 Offer is full and fair, delivers an above-market multiple and a full premium for control, and represents the best way for shareholders to realise the value of their Rinker shares.
