Luxembourg/Rotterdam, March 16, 2007 - Arcelor Mittal and Noble International, Ltd. (NASDAQ: NOBL) ("Noble"), North America's largest producer of laser-welded steel products, announced today that they have signed a definitive agreement for the combination of their laser-welded tailored blanks businesses.  Arcelor Mittal and Noble had previously announced on 27 October 2006 that they had signed a binding Letter of Intent for the combination of their businesses.

Under the terms of the transaction announced today, Arcelor Mittal will receive from Noble, in exchange for its laser-welded blanks business in western and eastern Europe, China, India and United States ("TBA"), consideration of US$300 million, which will consist of approximately $131,250,000 in a combination of cash, a Noble note and assumption of certain TBA financial obligations and 9,375,000 shares of Noble common stock with an agreed value of $18 per share.  Upon completion, Arcelor Mittal will become the largest stockholder of Noble, owning approximately 40% of the issued and outstanding common shares.  Arcelor will also obtain four of nine seats on Noble's board of directors.

Completion of the transaction is expected to occur in June 2007, and is subject to a number of conditions, including Noble shareholder approval, receipt by Noble of not less than $165 million in debt financing, anti-monopoly clearances in the United States, Canada and Europe and other customary conditions.

In addition, Arcelor and Noble will seek to include in the transaction as soon as practicable the tailored blank business operated by Powerlasers, a unit of Dofasco, Inc. that Arcelor acquired in early 2006, for additional consideration estimated at $50 million based on final determination of 2006 financial performance of Powerlasers.  The stock of Dofasco is held in a Dutch trust, the trustees of which will control any decision to sell any Dofasco assets.

TBA is a leading European manufacturer of tailored blanks.  Its business includes eight plants in Europe, one plant in the United States, a 25% joint venture in China and a 50% joint venture in India.  TBA employs about 670 people.  TBA's total revenues for 2006 were euro 415 million (US $540 million), with EBITDA of approximately euro 52 million (US $67 million). [Subject to review and comment by Noble.]

Noble is North America's largest laser welder with laser-welded flat blanks and laser-welded tubular products solutions for the automotive industry.  The company operates 12 production facilities in the United States, Canada, Mexico and Australia, and employs more than 2,000 people.  Noble's estimated pro forma 2006 revenue is approximately $600 million, with EBITDA of $56 million.

Michel Wurth, Member of the Arcelor Mittal Group Management Board said: "The signing of the agreement for this transaction is great news for both businesses. The combination of our leading position in Europe with Noble's leading position in the US will create a truly global business, for the benefit of our global automotive customers."
