ELK Elkcorp

ElkCorp (NYSE: ELK), a manufacturer of premium roofing and building products, today announced that its Board of Directors, on the recommendation of its Special Committee of independent, non-management directors and with the assistance of its legal and financial advisors, has recommended that the Company�s shareholders reject the $40.00 per share cash tender offer from Building Materials Corporation of America (�BMCA�), which was submitted on December 20, 2006. The Board reached its determination based, among other factors, on its belief that the tender offer is excessively conditional, lacks appropriate financing and is potentially illusory. Complete information on the Board�s recommendation can be found in the Company�s Solicitation/Recommendation Statement on Schedule 14D-9 filed today with the Securities and Exchange Commission. The Company noted, however, that it is in active negotiations with BMCA and its affiliate, Mr. Samuel Heyman, to develop a transaction that would merit recommendation to ElkCorp�s shareholders. To this end, ElkCorp has been providing, and continues to provide, BMCA and Heyman Investments with access to the Company (including facilities, documents and personnel) to allow BMCA to conduct an extensive due diligence investigation, including access to the information provided to Carlyle and other bidders, as well as additional information not previously made available to The Carlyle Group or other bidders. ElkCorp announced on December 18, 2006 that it has agreed to be acquired by an affiliate of Carlyle in an all-cash merger transaction in which ElkCorp shareholders would receive $38.00 in cash for each outstanding ElkCorp share. The Special Committee and the Board continue to recommend the Carlyle transaction at this time. About ElkCorp ElkCorp, through its subsidiaries, manufactures Elk-brand premium roofing and building products (90% of consolidated revenue) and provides technologically advanced products and services to other industries. Its common stock is listed on the New York Stock Exchange (NYSE:ELK). www.elkcorp.com. Forward Looking Statements.
