OBJECTIVES

The proposed Final Judgment filed in this case is intended to ensure that the defendant promptly divests Dofasco or the Alternative Business. The purpose of the divestiture is to ensure the establishment of a viable competitor in the production and sale of Tin Mill Products in order to remedy the anticompetitive effects that the United States alleges would otherwise result from Mittal Steel's acquisition of Arcelor. This Hold Separate Stipulation and Order ensures that prior to such divestiture (a) the Alternative Business is preserved for possible divestiture and (b) the Dofasco Business is operated as a competitively independent, economically viable, and ongoing business concern that will remain independent and uninfluenced by the consummation of Mittal Steel's acquisition of Arcelor, and that competition is maintained during the pendency of the ordered divestiture.

III.

JURISDICTION AND VENUE

This Court has jurisdiction over the subject matter of plaintiff's Complaint alleging that the proposed acquisition of Arcelor by Mittal Steel would violate Section 7 of the Clayton Act (15 USC §18), and the defendant does not object either to the Court's exercise of personal jurisdiction over it in this case, or to the propriety of venue of this action in the United States District Court for the District of Columbia. The defendant authorizes Cleary Gottlieb Steen & Hamilton LLP to accept service of all process in this matter on their behalf.
