QSC consolidates stock market listings to Frankfurt - voluntary delisting from NASDAQ

Cologne, February 25, 2002. QSC AG, Germany's professional DSL provider, plans to consolidate the parallel trading of its shares on both NASDAQ and Frankfurt's Neuer Markt. To this end, the company will voluntarily delist from NASDAQ in order to concentrate the trading of its shares on the Neuer Markt of the Frankfurt Stock Exchange. The delisting is expected to occur at the close of trading on April 2, 2002. Since its initial public offering in April 2000, the shares of QSC AG have been quoted on the NASDAQ in the form of American Depositary Shares (ADS) with the symbol QSCG. One ADS is equivalent to two ordinary bearer shares of QSC AG's common stock.

The efforts of maintaining a listing on the NASDAQ are not in proportion to the extremely low trading volume of QSC's ADSs on NASDAQ. During the fourth quarter of 2001, approximately 97 percent of all trading in QSC's shares on average occurred on the Neuer Markt of the Frankfurt Stock exchange.

QSC's ADS program will be discontinued at the same time as the NASDAQ delisting. QSC expects that this decision will not only achieve cost savings, but also result in an increased trading volume of its shares on the Neuer Markt. Preparation of the QSC's financial statements in accordance with US GAAP accounting standards will not be affected by the NASDAQ delisting in the United States.
