Tripath Technology Appeals Staff Determination Letter from Nasdaq.

SAN JOSE, Calif. -- Tripath Technology Inc. (Nasdaq:TRPH) today announced that it has received and is appealing, a Staff Determination Letter from Nasdaq. The Staff Determination Letter, which was received on May 26, 2005, indicates that the Staff had on April 25, 2005 notified the Company that the market value of its listed securities had been below the minimum $50 million required for inclusion set forth in Marketplace Rule 4450(b)(1)(A) for the previous 10 consecutive trading days and in accordance with Marketplace Rule 4450(e)(4) the Staff had provided the Company with 30 calendar days, or until May 25, 2005, to regain compliance. The Staff Determination Letter further indicates that the Company has not regained compliance in accordance with Marketplace Rule 4450(e)(4). Accordingly, the common stock of Tripath Technology Inc. is subject to delisting from the Nasdaq National Market.

Tripath Technology Inc. previously disclosed in its Form 8-K filed on April 29, 2005, that on April 26, 2005 it had received a letter from The Nasdaq Stock Market informing the Company that for the last thirty consecutive business days, the bid price of Tripath's common stock had closed below the minimum $1.00 per share requirement for continued inclusion set by Marketplace Rule 4450(b)(4), and that, in accordance with Marketplace Rule 4450(e)(2), the Company was being provided 180 calendar days, or until October 24, 2005, to regain compliance.

Tripath Technology Inc. is filing a request for a hearing before the Nasdaq Listing Qualifications Panel to appeal the Staff Determination Letter. At the hearing, Tripath Technology Inc. will also address its compliance with Marketplace Rule 4450(b)(4). The delisting process will be stayed, and the common stock of Tripath Technology Inc. will continue to be traded on the Nasdaq National Market until the panel makes a final decision. There can be no assurance that the panel will grant the Company's request for continued listing.

If the appeal of Tripath Technology Inc. is unsuccessful, the Company intends to apply to transfer the listing of its common stock to the Nasdaq SmallCap Market. Tripath Technology Inc.'s common stock will remain listed on the Nasdaq National Market while a listing application for the Nasdaq SmallCap Market is being reviewed. If Nasdaq approves the transfer to the Nasdaq SmallCap Market - and there can be no assurance that Nasdaq will do so - shares of Tripath Technology Inc. common stock would continue to be listed and traded under the existing ticker symbol, TRPH.
