                       RECEIPT OF SHAREHOLDER APPROVALS


RMC and CEMEX announced today that at a Court Meeting and an Extraordinary
General Meeting of RMC Shareholders held earlier today in connection with the
recommended Acquisition by CEMEX of RMC all the resolutions proposed received
overwhelming support from shareholders.

At the Court Meeting a majority in number of RMC Shareholders who voted
(either in person or by proxy), representing 99.98% by value, voted in favor
of the resolution to approve the Scheme. The resolution was accordingly
passed.

At the Extraordinary General Meeting the resolution proposed to approve the
Scheme and provide for its implementation was also passed by the requisite
majority.

The final results were as follows:

Court Meeting:  113,711,936 voted in favor, and 24,912 voted against.

Extraordinary General Meeting: 114,937,886 voted in favor, and 94,640 voted
against.

CEMEX UK acquired 50,000,000 RMC Shares, representing approximately 18.8% of
the issued share capital of RMC, on 27 September 2004 as announced on that
day. The voting rights conferred by these RMC Shares were not exercised at the
Meetings.

Regulatory reviews by the E.U. and U.S. anti-trust authorities are underway.
RMC and CEMEX expect to receive regulatory clearances in due course and it is
expected that the Scheme will become effective on 12 January 2005. If this
position changes, a further announcement will be made.

Terms used in this announcement shall have the same meanings as set out in the
Scheme document dated 25 October 2004.

In light of the Acquisition, RMC will now no longer be releasing a Trading
Review on 16 December 2004, as had previously been planned prior to the
announcement of the Acquisition.
