ArcelorMittal Prices Common Stock and Convertible Senior Note Offerings

Luxembourg, April 29th, 2009 (22:00 CET) – ArcelorMittal (“the Company” or "the Issuer") ") is pleased to announce the pricing of its offerings of common shares and convertible senior notes, announced earlier today.

The Company announces that it has now priced its common shares and convertible senior notes offerings. Total aggregate proceeds from the offerings are approximately $3.5 billion (exclusive of any proceeds attributable to the underwriters’ possible exercise of their over-allotment options described below) or $4 billion (assuming full exercise of those options), in each case before deduction of underwriting discounts and commissions.

The Company has agreed to sell 125,143,915 common shares at a public offering price of 17.10 EUR (US$22.77 at a $/EUR conversion rate of 1.3318) per common share. In addition, the Company has granted the underwriters an option to purchase up to an additional 15,738,719 common shares in the 30 day period following the date hereof.

The Company also announced the pricing of its public offering of $700 million aggregate principal amount of 5 percent convertible senior notes due May 15, 2014. The Company has granted the underwriters an option to purchase up to an additional $100 million aggregate principal amount of convertible senior notes in the 30 day period following the date hereof.  Interest on the convertible senior notes will be paid semi-annually at a rate of 5 percent per year, and the convertible senior notes will mature on May 15, 2014, unless earlier repurchased or converted. The convertible senior notes will be convertible at the holder’s option into shares of ArcelorMittal common stock (or, at the option of

Page 1 of 4

ArcelorMittal, into cash or a combination of cash or common stock) at an initial conversion ratio of 33.1675 shares of common stock per $1,000 principal amount of convertible senior notes, which is equivalent to an initial conversion price of approximately $30.15 per share of common stock, subject to adjustment in certain circumstances.  This initial conversion price represents a premium of approximately 32.4 percent relative to the public offering price of ArcelorMittal’s common stock of 17.10 EUR (US$22.77 at a $/EUR conversion rate of 1.3318) per share in the common stock offering.

The offerings are scheduled to close on May 6, 2009, subject to satisfaction of customary conditions. The closing of each offering is not contingent on the closing of the other.

The Company intends to use the proceeds of the common stock offering for general corporate purposes and to strengthen its balance sheet and the proceeds of the convertible senior note offering to lengthen its debt maturity profile and refinance existing indebtedness under various revolving credit facilities, with maturities ranging from 2010 until 2012.

Goldman Sachs International is acting as Sole Global Coordinator and Bookrunner for the offerings.

CALYON and Société Générale Corporate & Investment Banking also are acting as Bookrunners. Morgan Stanley is acting as a Joint Bookrunner. BNP Paribas, ABN AMRO, HSBC Bank Plc, Citigroup and JPMorgan Chase are acting as Co-Bookrunners.

Before you invest, you should read the prospectus in that registration statement and other documents the Issuer has filed with the SEC for more complete information about the Issuer and this offering.
