( BW)(ESMERTEC) Bookbuilding Period for Esmertec IPO Extended by Two Days until Friday, July 1; First Trading on SWX Swiss Exchange Envisaged for Monday, July 4

Business Editors/Technology Editors

DUEBENDORF-ZURICH, Switzerland--(BUSINESS WIRE)--June 30, 2005--Esmertec(TM), a leading global, independent developer of software solutions for mobile handsets and embedded devices, announced today that its envisaged IPO has attracted very strong demand and that the order book is currently covered over 9 times at CHF 20, the top end of the price range

Following the publication of the Preliminary Offering Memorandum on June 14, Esmertec has received letters from Tao Group Limited generally referencing certain patents and patent applications of the Tao Group. The Tao Group, based upon its misinterpretation of information posted on Esmertec's website, has expressed concerns that Esmertec's technology may overlap with certain of its asserted patent rights.

Following confirmation from intellectual property lawyers in the United States, Esmertec has found that the statements made by the Tao Group are without merit and erroneous. If required, Esmertec will vigorously defend its interests and does not expect that the costs of any such legal action would be material

The Board of Directors and the management of Esmertec as well as the Joint Bookrunners, UBS Investment Bank and Deutsche Bank, have decided to provide this information to potential investors prior to pricing the envisaged IPO. Therefore, the bookbuilding period will be extended until noon on Friday, July 1 and the first day of trading on the Main Board of the SWX Swiss Exchange is expected on Monday, July 4.
