Cummins and Russian Manufacturer KAMAZ Form Joint Venture to Produce Mid-Range Engines.

MOSCOW -- Cummins Inc. (NYSE:CMI) and KAMAZ Inc., the largest vehicle manufacturer in Russia, announced today the signing of a joint venture agreement to produce B Series engines (120-275 horsepower) under the name ZAO Cummins Kama.

The 50-50 joint venture will build on the Cummins and KAMAZ relationship that dates from the early 1980s. Among customers of the new company are KAMAZ trucks and buses, as well as trucks, buses and agricultural equipment produced by other manufacturers in Russia, Belarus and the Ukraine. The engines will be produced in two stages to comply with Euro II and Euro III standards for diesel emissions.

The B Series engines will be manufactured at the joint venture facilities, co-located with KAMAZ in Naberezhnye Chelny, Tatarstan, about 700 miles east of Moscow. The first engines will be assembled in early 2006.

"We are very excited about this new joint venture with our friends at KAMAZ," said Tim Solso, Cummins Chairman and Chief Executive Officer. "Cummins will benefit from its association with this highly respected original equipment manufacturer and its extensive dealer network in the Russian market. KAMAZ will gain from the use of Cummins dependable clean diesel engines and will have access to our new business and manufacturing technologies."

As part of the joint venture agreement, Cummins engines will be serviced through the extensive KAMAZ network of 150 Autocenters, the largest in the Commonwealth of Independent States, as well as the Cummins independent dealer network.

Steve Chapman, Cummins Group Vice President - Emerging Markets and Businesses, and Irek F. Gumerov, Deputy General Director of KAMAZ, signed the joint venture agreement at the KAMAZ offices in Naberezhnye Chelny.

"Two years ago we began selling a six-ton truck to the Russian market, and a Cummins engine was at the heart of our great success with this product," said Sergey Kogogin, General Director of KAMAZ. "Cummins understands the potential of the Russian market and the opportunities that exist with KAMAZ.

"By establishing a joint venture, we have taken the next step toward cooperation. Now we are not just a seller and buyer, but business partners on an international scale," he added.
