ElkCorp Issues Statement Regarding Two Different Tender Offers.

DALLAS -- ElkCorp (NYSE:ELK), a leading manufacturer of roofing and building products, today confirmed that it has received notice of a cash tender offer to purchase all of ElkCorp's outstanding shares for $42.00 per share by an affiliate of Building Materials Corporation of America (BMCA). The Company also noted that BMCA has terminated its previous tender offer of $40.00 per share.

The Special Committee and the Board of Directors, consistent with their fiduciary duties and the Company's obligations under its existing merger agreement with The Carlyle Group (Carlyle), will review the BMCA tender offer and make a recommendation to ElkCorp's shareholders. The Board urges its shareholders not to take any action with respect to the BMCA offer until the Board makes its recommendation.

On January 16, 2007, ElkCorp announced that it has entered into an amended merger agreement with Carlyle, under which Carlyle yesterday commenced a tender offer to acquire all of ElkCorp's outstanding shares for $40.50 per share. The revised Carlyle tender offer represents a $2.50 increase over the $38.00 price per share provided in the original merger agreement with Carlyle, which was announced on December 18, 2006. The Carlyle tender offer will expire at midnight on the 20th business day following and including the commencement date, unless extended in accordance with the terms of the merger agreement and the applicable rules and regulations of the Securities and Exchange Commission. The Board, at this time, continues to recommend that shareholders accept the Carlyle tender offer.
