October 30, 2006 - Austrian C.A.T. oil AG (O2C, ISIN: AT0000A00Y78),
one of the leading providers of oil and gasfield services in Russia
and Kazakhstan, has announced the appointment of Ronald Harder (43)
to the position of Chief Financial Officer effective November 1,
2006.

Ronald Harder succeeds Egbert Diehl, who turns 65 in January 2007.
After having contributed to the preparation and management of the
successful IPO as well as to the publication of the company’s initial
quarterly reports, the outgoing CFO now wants to devote more time to
his consulting firm and his real estate investments. Egbert Diehl
will leave C.A.T. oil on November 15, 2006, but will continue to
serve the company as a consultant.

Ronald Harder has extensive experience in the management of publicly
listed companies. Prior to joining C.A.T. oil AG Harder was employed
by B&L Immobilien AG, Hamburg, where he had been sole Executive Board
member since 2003. Prior to that Harder served as CFO of Datasave AG,
Hamburg, and as CFO of zapwerk AG, Hamburg. He began his professional
career with Hamburger Sparkasse, where he worked in various positions
for a period of 19 years. In 2000, as Head of Finance and Accounting,
he played a major role in the creation of Hanseatische i-Bank AG, the
direct bank subsidiary of Hamburger Sparkasse.

"We thank Egbert Diehl for his outstanding efforts in preparing
C.A.T. oil AG for the IPO. During the first half-year following the
IPO he also contributed significantly to solidifying investor
confidence by representing the company in the capital markets. In
Ronald Harder we have acquired an experienced and qualified
successor, who can be counted on to fully support C.A.T. oil AG in
its growth and who will continue to communicate effectively with our
investors," said Dr. Gerhard Strate, Chairman of the Supervisory
Board of C.A.T. oil AG.

About C.A.T. oil AG: Austria-based C.A.T. oil AG (O2C, ISIN:
AT0000A00Y78) is one of the leading providers of oil- and gasfield
services in Russia and Kazakhstan. C.A.T.oil’s core business is
hydraulic fracturing, a process which helps to open up oil- and
gas-bearing rock formations in order to increase or even enable oil
and gas production. The C.A.T.oil crews use state-of-the-art methods
and technologies to generate high pressure in the oil or gas
reservoirs concerned. This pressure causes cracks to appear in the
rock through which oil or gas can be produced in larger quantities
from the production well, and hence efficiently boosts extraction,
particularly in the case of deposits that are difficult to develop or
low-output wells. In addition, hydraulic fracturing can be used to
revitalize wells that have previously been idle. The Company has its
headquarters in Baden near Vienna and employed 2,230 people at the
end of 2005, most of whom are based in Russia and Kazakhstan.
Customers include leading oil and gas producers such as Gazprom,
KazMunaiGaz, LUKOIL, Rosneft, and TNK-BP. C.A.T.oil has been listed
in the Prime Standard of the Frankfurt Stock Exchange since May 4,
2006, and has been a member of the SDax since September 18, 2006.
