September 29, 2006 - Austria-based C.A.T. oil AG (O2C, ISIN:
AT0000A00Y78), one of the leading providers of oil and gas field
services in Russia and Kazakhstan, has signed a strategic partnership
agreement with RussNeft OAO NK, one of Russia’s 10 biggest oil
producers. This represents the third strategic partnership the
company has entered since the successful IPO on the Frankfurt Stock
Exchange in May 2006.

RussNeft, one of Russia’s younger oil groups, was created in 2002 by
the former President of SLAVNEFT an oil company which has meanwhile
been taken over by Anglo-Russian TNK-BP. Since its formation four
years ago, RussNeft has grown to become one of Russia’s major oil
producers. The vertically integrated group with high growth potential
presently owns 23 producing entities, 4 oil refineries and an
extensive sales network for oil and oil products. The company has a
current annual output of around 119 million barrels of crude oil.
RussNeft has access to proven oil reserves of 4.5 billion barrels and
reported a 2005 net profit of US$ 150 million on sales of US$ 2.4
billion. The company has announced plans for an IPO in 2007.

For some years now, C.A.T. oil has already been working at RussNeft
production sites in the western half of Russia and West Siberia.
C.A.T. oil will render services to the production entities of
RussNeft in a long term program to support its continued expansion.
The company is officially aiming to boost production to between 140
and 175 million barrels per year over the next two to three years
using C.A.T. oil AG’s experience and cutting edge technologies.

"After entering into two partnerships with Gazprom subsidiaries OOO
Burgaz and Gazprom-Neft, I am delighted to intensify the existing
collaboration with our rapidly growing business partner, RussNeft.
Since its formation, RussNeft looks back on an impressive expansion
story and has massive potential for the future. RussNeft’s faith in
our services underscores its trust in our technologies and
expertise," says Manfred Kastner, Chief Executive Officer of C.A.T.
oil AG. www.catoilag.com

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.
