Wien (euro adhoc) - In the context of a possible exercising of call
options and convertible bonds on shares of RHI AG (also see the ad
hoc release of RHI AG of January 11, 2007) on the part of the MS
Private Foundation (MSPF) of the Austrian investor Martin Schlaff the
MSPF has informed RHI AG that, due to the existing direct and
indirect majority stake that RHI AG holds in Didier-Werke
Aktiengesellschaft (DWAG) based in Wiesbaden, the point of law of a
possible mandatory takeover bid by MSPS to the shareholders of DWAG
may arise in accordance with the German Securities Acquisition and
Takeover Act (WpÜG).

In this respect, RHI AG states that in principle it does not intend
to accept a possible mandatory takeover bid by MSPS regarding the
shares of DWAG, especially not at the valuations in the range of the
current share price or the current minimum offer price in accordance
with German takeover legislation because, as is generally known, the
Didier Group forms an integral part of the global refractories
activities of the RHI Group.

In the view of RHI AG, there is also the possibility to avoid a
mandatory bid because in this context at least number three of the
grounds for exemption in § 9 of the effective Offer Ordinance of the
German Securities Acquisition and Takeover Act would become effective
as the book value of the interest held in DWAG, directly and
indirectly, amounts to less than 20% of the assets recorded in the
books of RHI AG. This would, of course, apply not only to the MS
Private Foundation but for any shareholder who, due to exceeding the
relevant investment limits would have to make a mandatory takeover
bid for Didier-Werke AG to RHI AG in accordance with German takeover
legislation.
