(“Kontron Mobile”) (OTC: “KMBC.ob”) not owned by Kontron AG at a price of $0.55 per share, net in cash (the “Offer”), expired at 5:00 p.m. New York City time on Friday, August 20, 2004. 124,905 shares of Kontron Mobile common stock were tendered and accepted for payment during the subsequent offering period, which, when added to the 5,487,273 shares that were acquired by KAC Acquisition upon the expiration of the Offer, as extended (Kontron AG previously announced that 5,507,273 shares had been tendered as of August 6, 2004, which included 20,000 shares that were tendered via submission of a notice of guaranteed delivery, such shares were not subsequently delivered and therefore were not validly tendered), and the shares already owned by Kontron AG, represent approximately 91% of the voting securities of Kontron Mobile.

As soon as the conditions for de-registration under the Securities Exchange Act of 1934 (the “Exchange Act”) are met, Kontron AG intends to cause Kontron Mobile to file a Form 15 with the Securities and Exchange Commission to terminate its registration under the Exchange Act, at which point Kontron Mobile’s common stock will be delisted from the Over the Counter Bulletin Board and Kontron Mobile will cease to file periodic reports under the Exchange Act.

Kontron AG will acquire the shares of Kontron Mobile that were not tendered through a “short-form” merger (the “Merger”). Under the Minnesota Business Corporations Act, KAC Acquisition, as the holder of more than 90% of the voting securities of Kontron Mobile, may cause Kontron Mobile to merge with and into KAC Acquisition without a vote of Kontron Mobile’s other shareholders. In the Merger, the remaining shareholders of Kontron Mobile, other than those who assert dissenters rights, will have their shares converted into the right to receive $0.55 per share. Kontron AG intends to cause Kontron Mobile to consummate the Merger with an effective date of October 1, 2004, the first day of the fourth calendar quarter. Upon the completion of the Merger, Kontron Mobile will be a wholly-owned subsidiary of Kontron AG and Kontron Mobile’s shares will no longer be publicly traded.
