WILBUR ROSS SAYS A MITTAL/ARCELOR COMBINATION WOULD HAVE BENEFITS FOR ALL SHAREHOLDERS

Chicago, February 27, 2006 A combination of Mittal and Arcelor would take consolidation to a new level and bring about further considerable benefits for all
stakeholders, said Wilbur Ross, Non Executive Director of Mittal Steel Company yesterday, Sunday 26thFebruary.

Speaking at a dinner in Chicago, Mr Ross said that despite the progress the industry has made in recent years towards a more consolidated business model, the sector is still afforded comparatively low ratings by the
financial markets. We still have to demonstrate that consolidation has progressed enough to have a real benefit in terms of reducing volatility and ensuring sustainability of earnings. Ultimately this will be improved by better management of
supply and demand which will further improve through having a more consolidated production base.

Mr Ross founded International Steel Group in 2002 after purchasing the assets of Bethlehem, LTV, Weirton, Acme and Georgetown which were in Chapter 11 due to the cyclical downturn of 2001. Speaking at the dinner, Mr
Ross explained why, despite ISG being a profitable, well-management stand-alone business with good growth prospects, the company took the decision to merge with Mittal Steel.

Trying to emulate the global profile and portfolio of Mittal Steel would have taken years, he said. Merging with them on the other hand would enable us to accelerate our long-term strategy and
growth plans, enabling our shareholders to benefit immediately from exposure to low-cost, fast-growing developing markets. The merger gave us the opportunity to deliver to

our shareholders immediately the business model that we wanted but that otherwise would have taken years for us to achieve.

Mr Ross compared the benefits of a Mittal/Arcelor merger to the Mittal/ISG merger. Combining with Mittal will accomplish Arcelors stated plan in the most efficient way, simultaneously creating a much
stronger, more balanced company that should act as the catalyst for a re-rating in the sector.

Mr Ross highlighted that a merger between Mittal and Arcelor would be a very natural combination as there is little geographic or product overlap. I have read various comments about the product mix of the two
companies being incompatible but this is not true, he said. We are producing exactly the same steels here in the United States as those Arcelor is producing in Europe. Plus we offer exposure to exciting growth markets where Arcelor has
been seeking to expand its own presence.

He concluded by explaining why having a presence in developing markets is important. Steel demand growth is directly linked to economic growth, he explained.  Under plausible scenarios of GDP and
population growth, the new demand likely to arise from the developing countries over the next 40  50 years should double the global consumption of steel.  He highlighted India as a tangible example, which currently has annual per capita
steel production of only 40kg, compared with 500kg in Western Europe, 700kg in Japan and 900kg in Korea. The growth opportunity is clear. As a shareholder I certainly want to have access to this growth potential as part of a balanced portfolio
of assets in both the developed and developing world, he said. Both Mr Mittal and Mr Dolle have spoken publicly many times on the need for there to be a handful of 100mt plus producers with a global footprint. This is exactly what this
transaction would create and overnight.
