SCHEDULE TO

     This Amendment No. 2 to the Tender Offer Statement on Schedule TO (this “Amended Schedule TO”) amends and supplements the Tender Offer Statement on Schedule TO originally filed with the Securities Exchange Commission on January 18, 2007 (the “Original TO”), by CGEA Investor, Inc. (“Purchaser”), a Delaware corporation and wholly owned subsidiary of CGEA Holdings, Inc. (“Parent”), pursuant to Rule 14d-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in connection with Purchaser’s offer to purchase all of the issued and outstanding shares of common stock, par value $1.00 per share (the “Common Stock”), of ElkCorp, a Delaware corporation (the “Company”), and the associated Series A Participating Preferred Stock purchase rights (the “Rights” and, together with the Common Stock, the “Shares”) at a price of $42.00 per Share, net to the seller in cash (less applicable withholding taxes and without interest). The terms and conditions of the offer are described in the Offer to Purchase, dated January 18, 2007 (the “Offer to Purchase”) and the related Letter of Transmittal, as amended and supplemented by the Supplement to the Offer to Purchase, dated January 22, 2007 (the “Supplement”), and related revised Letter of Transmittal (which, together with the Offer to Purchase and the Supplement, and any amendments or supplements thereto, collectively constitute the “Offer”). This Amendment No. 2 is being filed on behalf of behalf of Purchaser and Parent. Capitalized terms used and not otherwise defined in this Amended Schedule TO shall have the same meanings assigned to such terms in the Schedule TO or the Offer to Purchase.

Items 1 through 11.

     Items 1 through 11 of the Schedule TO are hereby amended and supplemented as follows:

     On January 29, 2007, the Company notified Parent of its intention to terminate the Amended and Restated Agreement and Plan of Merger (the “Merger Agreement”), dated as of January 15, 2007, as amended by the First Amendment thereto, dated as of January 21, 2007, pursuant to Section 7.1(g) of the Merger Agreement. On January 30, 2007, Parent and Purchaser notified the Company that Parent and Purchaser determined not to submit a revised proposal in response to the Company’s intention to terminate the Merger Agreement. On January 30, 2007, Parent and Purchaser also informed the Company that they agreed to waive the five business day waiting period in Section 7.1(g) of the Merger Agreement. On February 9, 2007, Parent and Purchaser received notice from the Company that the Company had terminated the Merger Agreement pursuant to Section 7.1(g) of the Merger Agreement in order to enter into a merger agreement with affiliates of Building Materials Corporation of America, which has announced an offer of $43.50 per share. On the same day, the Company paid an affiliate of Purchaser a termination fee of $29.0 million in cash, as required by Section 7.3(a) of the Merger Agreement. Also on February 9, 2007, as permitted by Section 14 of the Offer to Purchase, Purchaser and Parent have terminated the Offer and issued a press release in connection therewith. The Offer had been scheduled to expire at midnight, New York City time, on February 14, 2007. The full text of a press release issued by Parent on February 9, 2007 announcing the termination of the Offer is filed as Exhibit (a)(1)(W) hereto. No Shares were purchased by Purchaser pursuant to the Offer, and Purchase instructed Mellon Investor Services LLC, the Depositary, to return all tendered shares to the tendering stockholders.
