Further to the acquisition by Holcim Ltd of minority interests in the
company, St. Lawrence Cement today announced the transfer of its Northeast
US assets to Holcim (US) Ltd. and the reorganization of its corporate
administrative and information technology services effective January 1,
2008.

As a result of this announcement, the company’s Mount Royal office will be
closed. The decision affects approximately eighty employees at the corporate
head office but does not impact the regional headquarters in Longueuil and
other Quebec operations which employ more than 1,000 people.

"Our decision to relocate our corporate administrative services to the
Concord office will allow us to realize significant benefits in efficiency
for our internal operations while maintaining our strong presence in
Quebec," explained Philippe Arto, President and CEO of St. Lawrence Cement
Group. "Our goals have always been to create value through strong vertical
integration with local management, operational excellence and efficient
administration and we believe this move supports those goals."
