Foster Company, a Pennsylvania corporation (“Parent”), and (ii) Parent. The Schedule TO relates to the offer by the Purchaser to purchase all of the outstanding shares of common stock, par value $1.00 per share (the “Shares”), of Portec Rail Products, Inc., a West Virginia corporation (“Portec”), at a purchase price of $11.80 per Share, net to the seller in cash, without interest thereon and less any applicable withholding or stock transfer taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase dated February 26, 2010 (which, together with any amendments and supplements thereto, collectively constitute the “Offer to Purchase”) and in the related Letter of Transmittal, copies of which are filed with the Schedule TO as Exhibits (a)(1)(A) and (a)(1)(B), respectively. Capitalized terms used and not otherwise defined in this Amendment No. 19 have the meanings assigned to such terms in the Schedule TO or the Offer to Purchase. This Amendment No. 19 is being filed on behalf of the Purchaser and Parent. Pursuant to General Instruction F to Schedule TO, the information contained in the Offer to Purchase, including all schedules and annexes thereto, is hereby expressly incorporated by reference in answers to Items 1 through 11 of the Schedule TO and is supplemented by the information specifically provided for herein.
