QSC and Broadnet agree on exchange ratio

Cologne, April 2, 2007. Today, the Supervisory Boards of QSC AG, Cologne, (ISIN DE0005137004 und ISIN DE000A0JQ4T8) and Broadnet AG, Hamburg, (ISIN DE0005490866) have approved a definitive agreement on the merger of Broadnet AG into QSC AG and the exchange ratio of shares. Accordingly, Broadnet shareholders will receive 12 QSC shares for 11 Broadnet shares.

The exchange ratio was determined on the basis of the company valuations conducted by both companies, with the assistance of IVA VALUATION & ADVISORY AG Wirtschaftsprüfungsgesellschaft, Frankfurt/Main. The valuations also considered the relevance of publicly quoted stock prices for both companies. The equity value (Unternehmenswert) was conducted on the basis of the applicable discounted earnings method (Ertragswertverfahren). The determined equity value amounts to € 5.28 per share for Broadnet AG, and to € 6.06 per share for QSC AG. However, the weighted average stock-exchange price during a period of 3 months before the announcement of the intention to merge on January 30, 2007, (according to sec. 5 para. 1 WpÜG-Angebotsverordnung) amounts to € 6.61 per share for Broadnet AG, and to € 5.18 per share for QSC AG. QSC AG und Broadnet AG have decided to incorporate the respectively higher amount for each of the participating companies into the exchange ratio, consequently € 6.61 per share for Broadnet AG and € 6.06 per share for QSC AG, in order to ensure the adequacy for both companies and their respective shareholders.

The adequacy of the exchange ratio has been approved today by the court-appointed joint merger auditor, PricewaterhouseCoopers AG Wirtschaftsprüfungsgesellschaft, Frankfurt/Main, today. The shareholders of Broadnet AG will vote on the draft of the merger agreement at the annual general meeting on May 23, 2007.
