ArvinMeritor Announces Sale of Purolator Filters Business to Bosch and MANN+HUMMEL

TROY, Mich., Feb. 23, 2006 -- ArvinMeritor, Inc. announced today that it has entered into a definitive agreement to sell its Light Vehicle Aftermarket (LVA) Purolator filters business in North America to Bosch and MANN+HUMMEL. The transaction is subject to regulatory approvals. Terms of the agreement were not disclosed. The agreement to sell Purolator is part of ArvinMeritor's previously announced strategy to divest its LVA businesses individually.

Bosch and MANN+HUMMEL intend to operate Purolator, which is based in Fayetteville, N.C., as a joint venture. Purolator is one of the largest manufacturers of oil, air, fuel (petrol and diesel) and cabin filters in the world, with production operations in Fayetteville; a distribution facility in Salt Lake City, Utah; and a marketing and administrative center in Brentwood, Tenn.

"The sale of Purolator is another key strategic step that enables us to focus on our core competencies and strengthen our financial position," said Chip McClure, ArvinMeritor chairman, CEO and president. "While Purolator is a strong business with a long heritage and a talented workforce, it is a business that no longer fits our long-term strategy.

"We are encouraged by the interest that potential buyers have shown in our global LVA businesses, and we continue to work diligently to divest these remaining businesses in a way that is fair to our employees and generates maximum value for our shareholders," said McClure.

Purolator North America -- a leading national brand and supplier of filtration products including air, oil and fuel filters -- has been manufacturing, marketing and distributing filters since 1923. In fact, the first automotive oil filter, patented by Ernest J. Sweetland and George H. Greenhalgh, was called a "Purolator." The Fayetteville, N.C., operation is the largest filter plant in the world. Approximately 984 employees at the 640,000-square-foot production facility and adjacent distribution warehouse serve the full range of aftermarket customers including retailers, distributors and installers. The business also operates a 110,000-square-foot distribution warehouse facility in Salt Lake City, Utah, employing approximately 10 people, and a 2,600-square-foot marketing and administrative center in Brentwood, Tenn., employing approximately 18 people. Key customers include Ford, GM, DaimlerChrysler, Toyota, Isuzu, Advance Automotive, Shell, Quaker State, Texaco, Pep Boys, The Aftermarket Auto Parts Alliance and O'Reilly Automotive. Today, the Purolator brand includes more than 2,000 part numbers for automotive, light truck and heavy-duty applications.
