CEMEX, S.A. de C.V. ("CEMEX") (NYSE: CX) announced today that it has received consents from holders representing a majority of the principal amount of its outstanding 9.625% Notes due 2009 (the "2009 Notes") authorizing certain proposed amendments to the indentures governing the 2009 Notes.

The consents were delivered pursuant to CEMEX's previously announced cash tender offer and consent solicitation for any and all of its outstanding 2009 Notes. The consent solicitation relating to the 2009 Notes expired yesterday at 12:00 noon New York City time (the "2009 Note Consent Expiration Time").

Holders of the 2009 Notes who have tendered their 2009 Notes and consented prior to the 2009 Note Consent Expiration Time will receive a total consideration of U.S.$1,221.10 per $1,000 principal amount of the 2009 Notes tendered (which includes the consent payment of U.S.$10.00). Holders of the 2009 Notes who have consented prior to the 2009 Note Consent Expiration Time without tendering their 2009 Notes will receive only the consent payment of U.S.$10.00 per $1,000 principal amount of the 2009 Notes with respect to which consents are delivered. Holders of the 2009 Notes who tender their securities before the expiration of the tender offer will not receive the consent payment portion of the total consideration set forth above.

The tender offer for the 2009 Notes is currently scheduled to expire at 12:00 noon, New York City time, on Thursday, October 14, 2004.
