A Further Step in the Merger Process: Deutsche Telekom and T-Online reach a Common Understanding over the Range for the Exchange Ratio

Both Companies Expect the Merger to be Effected at an Exchange Ratio in a Range of between 0.45 and 0.55 Deutsche Telekom Shares for one T-Online Share

Deutsche Telekom and T-Online have today reached a common understanding regarding the exchange ratio range in connection with the proposed merger of T-Online International AG into Deutsche Telekom AG. Both companies expect the exchange ratio for the shares, which will be set forth in the merger agreement, to be between 0.45 and 0.55 Deutsche Telekom shares for one T-Online share.

This range was determined on the basis of the current status of the company valuations as conducted by Deutsche Telekom and T-Online with the assistance of KPMG and Warth & Klein, respectively. In preparation of the statutory merger under German law as contemplated by KMPG and Warth & Klein have been mandated by Deutsche Telekom and T-Online, respectively, to support the Management Boards in the preparation of the company valuations on the basis of the applicable discounted earnings methodology (Ertragswertverfahren) in accordance with the valuation standards issued by the Institut der Wirtschaftspruefer e.V. (IDW S1 neue Fassung), as well as to assist them in the determination of an appropriate merger exchange ratio.

Based on the current status of the valuations, both companies furthermore expect the IDW S1 discounted earnings values (Ertragswerte), established for the purpose of determining the merger exchange ratio, not to be below EUR 27.00 per Deutsche Telekom share and EUR 14.00 per T-Online share.

On the basis of the current findings, the anticipated exchange ratio for the T-Online shares is in any event below the price relation between the voluntary public tender offer of EUR 8.99 per T-Online share, and the closing price of Deutsche Telekom's shares, both at the time of announcement of the transaction (09 October 2004) of EUR 15.22, and at the time of the publication of the offer document (26 November 2004) of EUR 15.90. The same applies to the relation between the offer price of EUR 8.99 and the Xetra closing price of EUR 16.20 for a Deutsche Telekom share as of 25 January 2005.

The completion of the valuation analysis, the merger agreement and merger report, as well as the finalisation of the review that is currently being performed by the court appointed auditor, is, from today?s perspective, expected for mid March. With the invitations to the respective AGM?s, shareholders of both Deutsche Telekom and T-Online will be granted access to, inter alia, the merger agreement, the merger report and the merger audit report of the court appointed independent auditor.

The offer period for the currently ongoing voluntary public offer of Deutsche Telekom for T Online ends on 4 February 2005 at 24:00 hrs CET. Deutsche Telekom will not increase the current offer price of EUR 8.99 per T-Online share, nor will Deutsche Telekom launch another voluntary public offer for T-Online shares after the upcoming expiration of the voluntary public offer on 4 February 2005.
