Arcelor: Release of the Board of Directors.

LUXEMBOURG -- Arcelor (ISIN:LU0140205948) (Pink Sheets:ARLOF) (Paris:LOR) Board of Directors met on Sunday June 11 and unanimously decided:

--to reject Mittal Steel's current revised offer,

--to recommend that shareholders support the proposed merger with Severstal,

--to set the price per share of the self tender offer at EUR 44,

--not to commence such self tender offer until after the publication of Mittal Steel's offer results, and

--to mandate Group Management Board to meet with Mittal Steel in order to review Mittal Steel's proposal to further improve its offer

On Sunday, June 11, 2006, Arcelor's Board of Directors met at headquarters under the chairmanship of Mr. Joseph Kinsch. Following a detailed review and analysis of:

1. the revised terms of Mittal Steel's unsolicited offer of May 19,
   2006 for all of the shares and convertible bonds of Arcelor;

2. the Mittal Steel standalone business plan recently delivered to
   Arcelor;

3. the letter sent to Arcelor by a minority of shareholders
   representing or claiming to represent some 30% of Arcelor capital;

4. the consequences of various timing scenarios for the proposed self
   tender offer.

and having consulted Morgan Stanley on the financial aspects of Mittal Steel's revised offer, the Board has unanimously concluded that:

--Mittal Steel's current offer is inadequate as it continues to undervalue Arcelor;

--the Severstal transaction is a more attractive alternative from a strategic, financial and social point of view;

and resolved that it unanimously:

--rejects Mittal Steel's current revised offer;

--recommends to Arcelor's shareholders and convertible bond holders not to tender into Mittal Steel's revised offer;

--recommends to Arcelor's shareholders to support the Severstal transaction at the general meeting scheduled for 30 June 2006;

--sets the price per share of the self tender offer at EUR 44;

--decides not to commence such self tender offer until after the day of the publication of Mittal Steel's offer results; and

--mandates that Arcelor's Group Management Board meets with Mittal Steel in order to review the improvements that Mittal Steel offered to make to its current offer.

Mittal Steel's offer for Arcelor is inadequate on the financial point of view as it continues to undervalue Arcelor.

The Arcelor Board notes that the revisions to Mittal Steel's offer announced on May 19, 2006, demonstrate that Mittal Steel's initial offer undervalued Arcelor. Notwithstanding the increase in the consideration offered by Mittal Steel, the Arcelor Board of Directors believes that this offer is still inadequate as it continues to undervalue Arcelor because:

--Mittal Steel's 34% increase was required to realign the consideration initially offered by Mittal Steel as a result of its underperforming share price relative both to Arcelor's share price (by 20% from 30 January 2006 to 17 May 2006) and the steel sector average;

--Mittal Steel's offer does not take into proper account Arcelor's operating and financial results for 2005 - which exceeded market expectations - and for the first quarter of 2006, nor Arcelor's strategic plan;

--the multiple implied by Mittal Steel's valuation of Arcelor does not show a control premium when compared with trading multiples of comparable companies;

--the multiple implied by Mittal Steel's valuation of Arcelor remains significantly lower than multiples used in recent transactions in the steel sector;

The Arcelor Board of Directors, which consulted Morgan Stanley in connection with its financial aspects, reiterates that Mittal Steel's revised offer is inadequate and recommends that Arcelor shareholders and convertible bond holders do not tender into Mittal Steel's offer.

Arcelor and Mittal Steel have diverging business plans

The meeting which took place recently between representatives of Arcelor and Mittal Steel regarding Mittal Steel's business plan confirmed that Mittal Steel's strategy is mainly volume driven while Arcelor's is margin driven. As a result of these diverging business models, the synergies generated by the proposed combination of Mittal Steel and Arcelor are on the low side compared to those generated by recent large steel sector mergers and compared to those generated by the proposed merger of Arcelor and Severstal.

The Severstal transaction: the most attractive strategic alternative

The Severstal transaction will create the world's steel champion and the most profitable steel company. The Severstal transaction represents a key step in the implementation of Arcelor's value plan and growth strategy and it is consistent with its strategic vision, business model and corporate values.

--  The Severstal transaction will create the world's steel
        champion as Arcelor and Severstal are complementary both from
        a geographical standpoint and an industrial standpoint.

        --  The combined company will offer an exceptional, balanced
            geographic presence with leadership both in developed
            markets (Europe, North America) and emerging markets
            (Brazil and Russia).

        --  From an industrial standpoint, the combination of high
            value-added products and low-cost integrated upstream
            operations will result in a combined company with one of
            the highest profit margins in the industry, generating a
            2005 pro forma EBITDA per tonne of EUR130. The combined
            entity will consolidate Arcelor's technology leadership
            and experience and will be the undisputed world leader in
            all product segments (flat carbon steel, long carbon steel
            and distribution). The combination will strengthen
            Arcelor's leadership in the automotive steel segment (with
            a worldwide market share over 20% - more than double that
            of its nearest competitor).

        --  Furthermore, the combined company will have outstanding
            resilience through the steel cycle.

    --  The Severstal transaction creates compelling value for
        shareholders. The combined company will rank amongst the
        world's most competitive steelmaking producers in both
        developed and emerging markets, and will be the only one with
        leading positions in Brazil and Russia. The merger will
        generate significant synergies and further growth
        opportunities with a new normalized EBITDA target for 2008 of
        EUR10bn under Arcelor conservative hypothesis.

    --  The Severstal transaction enables Arcelor to continue its best
        practice corporate governance model. The agreement with Alexey
        Mordashov includes features designed to maintain Arcelor's
        corporate governance model. Several of these, such as the
        independence of a majority of the board, the independence of
        board committees and the mandatory offer threshold will be
        added to the by-laws.

The Severstal transaction does not preclude Mittal Steel's offer

The Arcelor board wishes to reiterate that neither the Severstal transaction, nor the way it is structured violate any law or any provision of the corporate charter.

By approving the Severstal transaction, the Board is certain that it acted not only lawfully, but also in the best interest of Arcelor, its stakeholders and its shareholders. In fact, the Board is convinced that in the absence of the Severstal proposal, Mittal Steel would not have improved its offer.

Moreover, the Severstal deal has been structured such that, if Mittal Steel acquires more than 50% of Arcelor's fully-diluted share capital, the Severstal transaction will be unwound. Additionally, if Mittal Steel achieves ownership levels below 50%, the Severstal transaction could be unwound by Alexey Mordashov himself.

The Arcelor Board of Directors has retained its full ability to continue carrying out its fiduciary duties in an unrestricted manner, in particular by being free to recommend a superior proposal.

Voting considerations

In light of the exceptional importance of the current events for the future of the Company, the Board decided to give the opportunity to those of the shareholders who would be opposed to the Severstal transaction to express their negative opinion by a simple majority vote of the currently outstanding shares of Arcelor and has called a shareholders meeting for the 30th of June to that effect.

Shareholders have therefore two opportunities to express their views. They can vote against the Severstal transaction at the general meeting on June 30 2006 and they can also express their preference for the Mittal Steel project by tendering into the Mittal Steel offer.

Given the importance of the Severstal/Arcelor transaction for the future of Arcelor, the 50% level for a rejection of this transaction is designed to encourage shareholder participation. A communication campaign will be undertaken by Arcelor to ensure that all shareholders are fully informed with respect to Severstal and the proposed transaction and that they participate in such meeting to express their preference. Putting the Severstal transaction to a vote with a 2/3 majority of those present or represented, as sometimes suggested recently, would mean that a small fraction of Arcelor's shareholders, representing at best 1/3 of Arcelor's capital, be given the right to eliminate this alternative.

The Arcelor Board of Directors therefore recommends that shareholders massively participate at the June 30 shareholders meeting and vote in favor of the Severstal transaction.

Arcelor's Board of Directors believes that the proposal by a minority of Arcelor shareholders is aimed at precluding the Severstal alternative in favor of Mittal Steel

Arcelor has received a letter requesting a shareholders meeting signed by entities claiming that they own approximately 30% of Arcelor's capital (the "Letter"). In such Letter, it is demanded that a general meeting be called in order to vote on a resolution (to be passed by a simple majority) requesting that an extraordinary shareholders meeting (EGM) be called later to approve the Severstal transaction (to be passed by a two-thirds majority).

The Board believes that this complex double shareholders meeting structure with different quorums and majority rules will deprive Arcelor shareholders of the Severstal alternative.

The Arcelor Board is very concerned that the scenario proposed has not been understood, due to its unnecessary complexity, and wants to make sure that investors are aware that:

a) regulatory delays and the likelihood of absence of a legal
       quorum on first call of such EGM would make it impossible to
       have it take place before mid-August at the soonest, long
       after the end of Mittal Steel's offer, thereby rendering such
       vote insignificant and useless;

    b) because of such timing, Mittal Steel would have the opportunity
        to vote any Arcelor shares acquired through the offer at such
        EGM against the proposed Severstal transaction;

    c) a small fraction of Arcelor's shareholders representing
        significantly less than 1/3 of the capital would be given the
        right to eliminate this alternative which the signatories of
        the Letter claim to praise.

Given the sensitivity of the matter in the present context as well as the fact that the elements of the Letter previously published in the press do not conform to the text of the Letter received, the Board has requested that certain important elements be verified in order to ensure that legal obligations are fully complied with.

In any event, Arcelor's Board has included the proposed resolution on the agenda of the June 30 shareholders meeting and recommends that shareholders vote against such proposal.

Arcelor Board of Directors sets price and timing of self tender offer

Following its prior decision to distribute a EUR 6.5bn amount to Arcelor shareholders, the Arcelor Board of Directors has decided that the price per share to be offered to Arcelor shareholders in connection with the Offre Publique de Rachat d'Actions to be submitted to Arcelor shareholders at the next EGM, on June 21, 2006, shall be EUR 44 per share which corresponds to the price per share paid by Alexey Mordashov with the cash portion of its contribution to the capital of Arcelor.

Taking into account investors concern in case of an overlap in terms of calendar between the Mittal Steel offer and this self-tender offer, the Board of Directors decided that, if the shareholders were to approve such self-tender offer, it will not be commenced until after the day of the publication of the Mittal Steel offer results. Therefore, the self-tender offer will have no influence on the ability of Mittal Steel to close its offer.

Committed to maximizing shareholder value and protecting the corporate interest, Arcelor Board of Directors requests Group Management Board to meet with Mittal Steel in order to review Mittal Steel's proposal to further improve its offer

The Arcelor Board of Directors rejects the current Mittal Steel offer and reiterates its full support of the Severstal transaction. These determinations are premised on a commitment to maximizing shareholder value and protecting the interest of the group, its employees and its stakeholders.

In line with this commitment, and having noted that Mittal Steel recently indicated that it was prepared to further improve its offer in the context of a recommended transaction, the Arcelor Board has mandated the Group Management Board to meet with Mittal Steel in order to explore such possible improvements and to report to the Board of Directors.
