          This Amendment No. 3 to the Tender Offer Statement on Schedule TO (this “ Amendment ”) is filed by Curtiss-Wright Corporation, a Delaware corporation (“ Curtiss-Wright ”), and Columbia Acquisition Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Curtiss-Wright (“ Purchaser ”). This Amendment amends and supplements the Tender Offer Statement on Schedule TO filed with the Securities and Exchange Commission on November 15, 2012, as amended and supplemented by Amendment No. 1 filed on November 30, 2012, and Amendment No. 2 filed on December 12, 2012 (together with any further amendments and supplements thereto, the “ Schedule TO ”), and relates to the offer by Purchaser to purchase each of the outstanding shares of common stock, par value $0.01 per share (the “ Shares ”), of Williams Controls, Inc., a Delaware corporation (“ Williams Controls ”), at a price of $15.42 per Share, net to the seller in cash, without interest thereon and less any required withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase dated November 15, 2012 (the “ Offer to Purchase ”) and the related Letter of Transmittal, copies of which are respectively set forth as Exhibits (a)(1)(A) and (a)(1)(B) thereto, and together with any amendments or supplements thereto, collectively constitute the “ Offer .”
          Except as otherwise indicated in this Amendment, the information set forth in the Schedule TO remains unchanged. Capitalized terms used but not defined herein have the meanings ascribed to them in the Schedule TO.
Items 1 through 9 and Item 11.
Items 1 through 9 and Item 11 of the Schedule TO are hereby amended and supplemented as follows:
“The initial offering period of the Offer expired at 11:59 p.m., New York City time, on Thursday, December 13, 2012. The Depositary for the Offer has advised Curtiss-Wright and Purchaser that, as of 11:59 p.m., New York City time, on December 13, 2012, a total of 6,605,243 Shares were tendered and not withdrawn pursuant to the Offer. This represents approximately 86.3% of the outstanding Shares (or approximately 85.0% of the fully-diluted Shares). All such Shares have been accepted for payment in accordance with the terms of the tender offer.
Purchaser has exercised the top-up option in accordance with the Merger Agreement, as a result of which Williams Controls issued additional Shares to Purchaser, at a price per Share equal to the price per Share being paid in the Offer, sufficient to allow Purchaser to effect a short-form merger pursuant to Section 253 of the DGCL, and the short-form merger was subsequently completed on December 14, 2012. Following the Merger, each Share not tendered in the Offer, other than those as to which holders exercise appraisal rights under Delaware law and those held by Curtiss-Wright or Williams Controls or their respective wholly owned subsidiaries, was converted into the right to receive $15.42 per Share in cash, without interest and less any required withholding taxes. This is the same price per Share being paid in the Offer.
The full text of the press release issued by Curtiss-Wright on December 14, 2012 in connection with the expiration of the Offer and the Merger is filed as Exhibit (a)(5)(C) hereto and is incorporated herein by reference.”
