This Amendment No. 6 amends and supplements the Tender Offer Statement on Schedule TO filed on February 24, 2005 with the Securities and Exchange Commission, as amended and supplemented by Amendment No. 1 to the Tender Offer Statement on Schedule TO filed on March 1, 2005, Amendment No. 2 to the Tender Offer Statement on Schedule TO filed on March 9, 2005, Amendment No. 3 to the Tender Offer Statement on Schedule TO filed on March 16, 2005, Amendment No. 4 to the Tender Offer Statement on Schedule TO filed on March 18, 2005 and Amendment No. 5 to the Tender Offer Statement on Schedule TO filed on March 24, 2005 (as so amended and supplemented, the "Schedule TO"), by Amherst Acquisition Co., a Texas corporation ("Subcorp") and a wholly owned subsidiary of Thrall Omni Company, Inc., a Delaware corporation ("Thrall Omni"), which is an affiliate of Duchossois Industries, Inc., an Illinois corporation ("DII"). The Schedule TO relates to the offer by Subcorp to purchase all of the outstanding shares of common stock, par value $0.01 per share (the "Shares"), of AMX Corporation, a Texas corporation ("AMX"), for $22.50 per Share, net to the seller in cash upon the terms and subject to the conditions set forth in the Supplement to the Offer to Purchase, dated March 16, 2005 (the "Supplement"), the Offer to Purchase, dated February 24, 2005 (the "Offer to Purchase"), and in the related Letter of Transmittal (which, together with the Supplement and the Offer to Purchase, and any amendments or supplements hereto or thereto, collectively constitute the Offer). Capitalized terms used but not defined herein shall have the meanings assigned thereto in the Offer to Purchase.
Item 11. Additional Information.
Item 11 of the Schedule TO is hereby amended and supplemented by the following:
The subsequent offering period expired at 5:00 p.m., New York City time, on April 7, 2005. Subcorp accepted all Shares properly tendered, as they were tendered, during the subsequent offering period and promptly paid for all such Shares at a price of $22.50 per Share, without interest, which was the same price offered for Shares tendered in the initial offering period. The Bank of New York, the Depositary for the Offer, has advised DII that, as of the expiration of the subsequent offering period, an aggregate of 832,832 Shares were validly tendered in the subsequent offering period. Together with the 10,015,173 Shares Subcorp acquired pursuant to the Offer and the 531,527 Shares Subcorp acquired pursuant to notices of guaranteed delivery, Subcorp acquired in the tender offer 11,379,532 Shares, representing approximately 92.5% of the outstanding Shares.
DII completed the acquisition of AMX through the merger of Subcorp with and into AMX, with AMX as the surviving corporation, in accordance with Article 5.16 of the Texas Business Corporation Act. Pursuant to the terms of the Merger Agreement, all remaining Shares (other than Shares owned by shareholders of AMX who properly exercise appraisal rights pursuant to the Texas Business Corporation Act) were converted into the right to receive $22.50 per Share in cash, without interest. As a result of the merger, the Shares will no longer be listed on the Nasdaq National Market.
On April 8, 2005, DII issued a press release, a copy of which is attached hereto as Exhibit (a)(5)(F) and is incorporated herein by reference. The press release announced the results of the Offer and the completion of the acquisition of AMX.
