Jena (euro adhoc) - The Management Board of DEWB AG (DEWB) has
resolved, with the consent of the Supervisory Board, to issue a
convertible bond with an issue volume of up to 20,000,000 euros. The
bond will have a maturity of 5 years with interest paid at 6.0
percent p.a. It will be divided into up to 20,000 part convertible
bonds each with a nominal value of 1,000 euros, entitling the holders
to convert them into DEWB shares at a price of 3.20 euros per share.
This corresponds to a conversion premium of approx. 25 percent based
on the average closing price of the preceding three trading days of
the DEWB share on the XETRA of 2.55 euros.

DEWB will use the funds raised from the issue to expand its
investment activity. This will enable new investment commitments to
be made independently of exits from the timing aspect. "Over recent
years the majority of our liquidity has been used for the rapid
reduction of debt as well as the development of the existing
investment portfolio. Following the successful strengthening of the
balance sheet structure we can therefore once again make an active
return to investment activities with new commitments and utilize the
attractive investment opportunities within our technology focus"
states Mirko Wäckerle, member of the DEWB Management Board. "The
issue of the convertible bond is a further step towards the planned
increase in the assets under management to more than 100 million
euros and to make DEWB the leading independent investment capital
provider for companies in the areas of photonics and sensor systems",
continues Wäckerle.

The bond is expected to be offered to DEWB shareholders for
subscription from September 17, to October 1, 2007 within the
framework of a subscription rights issue. For each 1,523 shares two
part convertible bonds can be purchased at the price of 1,000 EUR
each. No public offering will be made. Part convertible bonds not
subscribed by shareholders will be offered by quirin bank AG to
institutional investors under the same terms and conditions. The
issue will be assisted by quirin bank AG and Close Brothers Seydler
AG. To enable investors to trade in the bonds on the stock market
DEWB is applying for the convertible bond to be authorized for
trading in the Open Market of the Frankfurt Securities Exchange.

The full terms and conditions of the convertible bond is expected to
be published within the framework of the subscription rights offering
to shareholders, on Thursday September 13, 2007 on the company´s
Homepage and in the "Börsenzeitung" as well as on Friday September
14, 2007 in the electronic "Federal Gazette" (Bundesanzeiger).
