Nalco Africa Signs Distributor Agreement with Tupelovox (Pty.) Ltd.

JOHANNESBURG, January 27, 2011 - Nalco Africa (Pty) Ltd. and Tupelovox (Pty) Ltd. have signed a
non-exclusive agreement under which Tupelovox will distribute Nalco's
industrial water and process treatment programs in South Africa to the
municipal and institutional markets.

"Nalco Africa is strongly committed to broad-based black economic
empowerment and the goal of strengthening the economy through the
participation of all citizens," said Paul Voorhout, Managing Director, Nalco
Africa. "Partnering with Tupelovox is a tangible demonstration of that
commitment. We will provide start up assistance to this 100 percent
black-owned enterprise, giving them the opportunity to help customers develop
and institute world-class industrial water treatment programs."

Under the distributor agreement, Tupelovox will be able to provide Nalco
Africa's broad range of innovative water treatment solutions to its customers
including the award-winning 3D TRASAR(R) automation technology which has
helped customers globally save more than one billion cubic meters of water
since it was introduced. Nalco Africa will also provide use of its
facilities, both technical and sales training to Tupelovox employees and
technical support as they work with Tupelovox customers.

"Water scarcity and water quality are critical issues facing South
Africa. To achieve the economic success needed to move our country and our
entire people forward, industry must find ways to grow while limiting its
total water use," said Eugene Sihle Ngcobo, Owner and Director, Tupelovox.
"Having access to Nalco's globally proven water treatment solutions and their
support and training will allow us to help our customers achieve that growth
while preserving and protecting those limited water supplies."
