Nalco Mobotec Signs Major Air Protection Contract in Poland with Zespol Elektrowni PAK SA

NAPERVILLE, Illinois, January 24, 2011 - Nalco Mobotec, a global leader in air protection technology, announced
that, as part of a consortium with engineering firm Remak Rozruch, it has
signed a contract with Zespol Elektrowni PAK SA for the modernisation of one
of the boilers at PAK's Patnow I Power Plant located in Konin, Poland.

Zespol Elektrowni PAK SA is one of the largest electrical power producers
in Poland. This project to be implemented at boiler no. 5 in Patnow I Power
Plant will result in the reduction of nitrogen oxide (NOx) emissions thereby
allowing ZE PAK to meet for this boiler the stringent new air emission
requirements under the EU Industrial Emissions Directive for 2016.

In addition, the increased combustion efficiency, assured by the
technology provided by Nalco Mobotec, will contribute to the improvement of
the boiler efficiency, which will allow ZE PAK to burn less lignite (brown
coal), resulting in significant fuel savings.

The modernisation will include the installation of Nalco Mobotec's
patented ROFA(R) (Rotating Opposed Fire Air) and ROTAMIX(R) technologies for
combustion optimisation and NOx reduction, in conjunction with modifications
undertaken by Remak Rozruch to upgrade the boiler firing and control systems.
The 50 million PLN (more than $16.5 million) project is scheduled for
completion in August 2012.

"Nalco Mobotec teams in Poland, Canada and the United States worked
closely with Remak Rozruch to develop a cost-effective offering to meet the
technical and budgetary needs of ZE PAK," said David Johnson, Nalco Executive
Vice President and President, Europe, Africa and Middle East. "This project
is a strong start to 2011 for our business in Poland and other regions
throughout Europe."

Nalco Mobotec's patented ROFA technology provides the rotation of the
fuel and air mixture in the entire volume of the furnace via an asymmetric
boosted over-fire air system. The result is a superior mixing of air, fuel,
chemicals and the proper temperature distribution that results in NOx
reduction and optimized combustion. Nalco Mobotec's ROTAMIX system combines
air injection nozzles with automatically regulated lances for the injection
of chemicals into the furnace where the temperature is most favorable.

"These two technologies combined, deliver to PAK a solution that
optimizes emissions reduction and minimizes capital expenditure," said Dwayne
Kearns, Nalco General Manager, Air Protection Technologies.
