merger, acquisition and takeover

Jena/London/Berlin, 14 April 2008 (euro adhoc) - Deutsche Effecten-
und Wechsel-Beteiligungsgesellschaft AG (DEWB) - Prime Standard/ISIN
DE0008041005 - has taken a stake in Nanotron Technologies Ltd.
(Nanotron), Berlin, within a financing round. DEWB acquired an 18.1
percent share and is taking over the role of co-lead investor with
the British Venture Capital investor zouk ventures, London. The
financing round has a volume of 11 million Euros. In addition to DEWB
and zouk ventures the existing shareholders Danfoss, PolyTechnos, IBB
- VC Fonds Berlin, as well as the Nanotron Management also
participated.

The Berlin-based chip designer Nanotron is a leader in the
development and sale of wireless sensor networks and solutions for
radio-based communication and localisation. The company´s main
product is the nanoLOC chip based on the reliable Chirp Spread
Spectrum (CSS) transmission system. This transmission system is
clearly superior to rival technologies and suited in particular to
communication as well as real time object monitoring (RTLS - Real
Time Location System) to a high level of positioning precision. Other
prominent features of Nanotron´s network solution are a fast and
low-cost installation, as well as high robustness, high reliability
on extensive ranges plus extremely low power consumption. Over recent
years the Chirp system has been integrated in the IEEE Standard
802.15.4a and work is underway to obtain ISO certification.

"The first applications for asset tracking in industry were based on
active RFID solutions. However, RFID does have its limits in terms of
precision locating. This is an area in which Nanotron is deploying
its product and so targeting the rapidly-growing RTLS market. The
annual growth rates of over 30 percent are the same as in the RFID
market," says Bertram Köhler, Member of the DEWB Management Board,
commenting on the first major new investment for three years. "With
its unique and patented technology, success in standardisation as
well as the highly experienced management team, there is significant
potential for Nanotron to gain clearly disproportionate benefit from
this growth. The fact that Nanotron has successfully attracted
high-profile key clients proves our investment decision," states
Köhler, who is now to become a member of the Nanotron Supervisory
Board.

"With its superior reliability and precision compared to other
technologies and the much lower energy consumption of the
transmission method, even in harsh transmission environments,
Nanotron´s system offers a wide range of potential uses; whether as
an industrial application e.g. for container and asset tracking,
modern traffic control systems or applications for the integration of
intelligent energy meters. The fast and straightforward assembly of
the necessary infrastructure enables users to implement these
networks on an ad-hoc basis in accordance with the "plug & play"
principle," explains Felix von Schubert, Partner at zouk ventures and
member of the Nanotron Supervisory Board.

"We are pleased with the fact that in DEWB we have attracted another
leading investor with expertise, one which has already invested
successfully in companies within our target market. We see the latest
investment by the existing shareholders as a demonstration of their
confidence in our work. We will use the funds raised from the
financing round to aggressively drive forward our international
expansion and significantly increase our market share in the area of
wireless network solutions," said Dr. Jens N. Albers, CEO of
Nanotron, on completion of the financing round.
