March 8, 2007 — Dofasco announced today that Jacques Chabanier, the company’s President and CEO, has announced his intention to resign, effective on the appointment of a successor by Dofasco's Board of Directors. Appointment of a successor is expected to be finalized within the next few weeks.

Mr. Chabanier will also step down as CEO of Quebec Cartier Mines, a wholly owned subsidiary of Dofasco.

"I believe this is the appropriate time to hand the reins of the company to an individual able to make a long-term commitment to Dofasco's success as a business unit of Arcelor Mittal's North American flat carbon steel division. My successor should have the opportunity to manage the transition and integration process," commented Mr. Chabanier.

Mr. Chabanier was appointed CEO in July, 2006, when he replaced Don Pether. Chabanier had worked with Dofasco from the time Arcelor acquired the company, earlier in that same year. A 35-year veteran of the steel industry, Chabanier had worked for Usinor, one of the companies that eventually merged to form Arcelor. At Usinor, he held various senior management positions until the formation of Arcelor, when he was promoted to the position of Senior Executive Vice President.

“I view Dofasco's future within Arcelor Mittal very optimistically as Dofasco enters the integration process with an ambitious plan to enhance the company's competitiveness, and leverage its ability to provide superior quality and service to its customers,” he concluded.

“Jacques has provided outstanding leadership to Dofasco throughout its initial integration with Arcelor, and its subsequent period as a stand-alone company under the Department of Justice's Hold Separate Order, which was lifted in February,” commented Lou Schorsch, Executive Vice President of Arcelor Mittal and CEO Flat Americas. “He passes on a strong company to his successor”.

Aditya Mittal, Chief Financial Officer and GMB member, said, "Mr. Chabanier has had a distinguished career with Arcelor Mittal and its predecessor companies. It was with great regret that the Management Board learned of his decision to return to Europe. We are nevertheless gratified that he will continue to lead Dofasco throughout the transition. On behalf of the Management Board I thank him for his service, particularly his excellent work at Dofasco."
