ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the U.S. Securities and Exchange Commission, which we refer to as the SEC, utilizing a shelf registration process. Under this shelf process, the securities described in this prospectus may be sold in one or more offerings. This prospectus provides you with a general description of the securities that may be offered. Each time securities are offered pursuant to this prospectus, we will attach a prospectus supplement to the front of this prospectus that will contain specific information about the terms of those securities and their offering. We may also add, update or change information contained in this prospectus by means of a prospectus supplement or by incorporating by reference information that we file with or furnish to the SEC. The registration statement that we filed with the SEC includes exhibits that provide more detail on the matters discussed in this prospectus. Before you invest in any securities offered by this prospectus, you should read this prospectus, any related prospectus supplements and the related exhibits filed with the SEC, together with the additional information described under the heading “Incorporation of Certain Documents by Reference.”

We are responsible for the information contained and incorporated by reference in this prospectus, any accompanying prospectus supplement and in any related free-writing prospectus we prepare or authorize. We have not authorized anyone to give you any other information, and we do not take any responsibility for any other information that others may give you.

ArcelorMittal is not making an offer to sell these securities in any jurisdiction where the offer or sale are not permitted. This document may only be used where it is legal to sell these securities.

You should not assume that the information contained or incorporated by reference in this prospectus or the prospectus supplement is accurate as of any date other than the date on the front cover of this prospectus. ArcelorMittal’s business, financial condition, results of operations and prospects may have changed since that date.

RISK FACTORS

An investment in the securities offered using this prospectus involves a high degree of risk. You should carefully consider the risks described below, together with the risks described in the documents incorporated by reference into this prospectus, and any risk factors included in the prospectus supplement, before making an investment decision. The Company’s business, financial condition and results of operations could be materially and adversely affected by any of these risks, and the trading price and liquidity of the securities offered using this prospectus could decline, in which case you may lose all or part of your investment. The risks described below are those known to ArcelorMittal and that it currently believes may materially affect it.

Risks Relating to ArcelorMittal

Each document incorporated by reference is current only as of the date of such document, and the incorporation by reference of such documents shall not create any implication that there has been no change in our affairs since the date thereof or that the information contained therein is current as of any time subsequent to its date. Any statement contained in such incorporated documents shall be deemed to be modified or superseded for purposes of this prospectus to the extent that a subsequent statement contained in another document we incorporate by reference at a later date modifies or supersedes that statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this prospectus.

FORWARD-LOOKING STATEMENTS

This prospectus, including the documents incorporated by reference herein, and the related prospectus supplement contain forward-looking statements based on estimates and assumptions. This prospectus and the related prospectus supplement contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, among other things, statements concerning the business, future financial condition, results of operations and prospects of ArcelorMittal, including its subsidiaries. These statements usually contain the words “believes,” “plans,” “expects,” “anticipates,” “intends,” “estimates” or other similar expressions. For each of these statements, you should be aware that forward-looking statements involve known and unknown risks and uncertainties. Although it is believed that the expectations reflected in these forward-looking statements are reasonable, there is no assurance that the actual results or developments anticipated will be realized or, even if realized, that they will have the expected effects on the business, financial condition, results of operations or prospects of ArcelorMittal.

These forward-looking statements speak only as of the date on which the statements were made, and no obligation has been undertaken to publicly update or revise any forward-looking statements made in this prospectus, the related prospectus supplement or elsewhere as a result of new information, future events or otherwise, except as required by applicable laws and regulations. In addition to other factors and matters contained or incorporated by reference in this prospectus and the related prospectus supplement, it is believed that the following factors, among others, could cause actual results to differ materially from those discussed in the forward-looking statements:

• recessions or prolonged periods of weak economic growth, either globally or in ArcelorMittal’s key markets;

• risks relating to continued weakness of the eurozone economy;

• the risk that excessive capacity in the steel industry may weigh on the profitability of steel producers;

• any volatility in the supply or prices of raw materials, energy or transportation, mismatches with steel price trends, or protracted low raw materials or steel prices;

• increased competition in the steel industry;

• the risk that unfair practices in steel trade could negatively affect steel prices and reduce ArcelorMittal’s profitability, or that national trade restrictions could hamper ArcelorMittal’s access to key export markets;

• the risk that ArcelorMittal may incur in the future operating costs when production capacity is idled or increased costs to resume production at idled facilities;

• increased competition from other materials, which could significantly reduce market prices and demand for steel products;

• risks relating to environmental and health and safety laws and legislation;

• laws and regulations restricting greenhouse gas emissions;

• the risk that ArcelorMittal’s high level of indebtedness could make it difficult or expensive to refinance its maturing debt, incur new debt and/or flexibly manage its business;

• risks relating to greenfield and brownfield projects;

• risks relating to ArcelorMittal’s mining operations;

• the fact that ArcelorMittal’s reserve estimates could materially differ from mineral quantities that it may be able to actually recover, that its mine life estimates may prove inaccurate and the fact that market fluctuations may render certain ore reserves uneconomical to mine;

• drilling and production risks in relation to mining;

• rising extraction costs in relation to mining;

• failure to manage continued growth through acquisitions;

• a Mittal family trust’s ability to exercise significant influence over the outcome of shareholder voting;

• any loss or diminution in the services of Mr. Lakshmi N. Mittal, ArcelorMittal’s Chairman of the Board of Directors and Chief Executive Officer;

• the risk that the earnings and cash flows of ArcelorMittal’s operating subsidiaries may not be sufficient to meet future funding needs at the holding company level;

6

• the risk that changes in assumptions underlying the carrying value of certain assets, including as a result of adverse market conditions, could result in impairment of tangible and intangible assets, including goodwill;

• the risk that ArcelorMittal’s investment projects may add to its financing requirements;

• ArcelorMittal’s ability to fund under-funded pension liabilities;

• the risk of labor disputes;

• economic policy, political, social and legal risks and uncertainties in certain countries in which ArcelorMittal operates or proposes to operate;

• fluctuations in currency exchange rates, particularly the euro to U.S. dollar exchange rate, and the risk of impositions of exchange controls in countries where ArcelorMittal operates;

• the risk of disruptions to ArcelorMittal’s manufacturing operations;

• the risk of damage to ArcelorMittal’s production facilities due to natural disasters or severe weather conditions;

• the risk that ArcelorMittal’s insurance policies may provide inadequate coverage;

• the risk of product liability claims;

• the risk of potential liabilities from investigations, litigation and fines regarding antitrust matters;

• risks relating to legal proceedings to which ArcelorMittal is currently, and may in the future be, subject;

• the risk that ArcelorMittal’s governance and compliance processes may fail to prevent regulatory penalties or reputational harm, both at operating subsidiaries and joint ventures;

• the fact that ArcelorMittal is subject to an extensive, complex and evolving regulatory framework and the risk of unfavorable changes to, or interpretations of, the tax laws and regulations in the countries in which ArcelorMittal operates;

• the risk that ArcelorMittal may not be able fully to utilize its deferred tax assets; and

• the risk that ArcelorMittal’s reputation and business could be materially harmed as a result of data breaches, data theft, unauthorized access or successful hacking.

These factors are discussed in more detail in the 2014 Form 20-F, including under “Item 3D—Key Information—Risk Factors.”

PRESENTATION OF CERTAIN INFORMATION

Definitions and Terminology

Unless indicated otherwise, or the context otherwise requires, references in this prospectus and related prospectus supplement to “ArcelorMittal,” “we,” “us,” “our” and “the Company” or similar terms are to ArcelorMittal, formerly known as Mittal Steel Company N.V. (“Mittal Steel”).

Financial Information

This prospectus (including the documents incorporated by reference herein) contains the audited consolidated financial statements of ArcelorMittal and its consolidated subsidiaries, including the consolidated statements of financial position as of December 31, 2013 and 2014, and the consolidated statements of operations, other comprehensive income, changes in equity and cash flows for each of the years ended December 31, 2012, 2013 and 2014. ArcelorMittal’s consolidated financial statements were prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).

The financial information and certain other information presented in a number of tables in this prospectus and any related prospectus supplement have been rounded to the nearest whole number or the nearest decimal. Therefore, the sum of the numbers in a column may not conform exactly to the total figure given for that column. In addition, certain percentages presented in the tables in this prospectus and any related prospectus supplement reflect calculations based upon the underlying information prior to rounding and, accordingly, may not conform exactly to the percentages that would be derived if the relevant calculations were based upon the rounded numbers.

Market Information

This prospectus (including the documents incorporated by reference herein) and any related prospectus supplement include industry data and projections about our markets obtained from industry surveys, market research, publicly available information and industry publications. Statements on ArcelorMittal’s competitive position contained in this prospectus are based primarily on public sources including, but not limited to, publications of the World Steel Association. Industry publications generally state that the information they contain has been obtained from sources believed to be reliable but that the accuracy and completeness of such information is not guaranteed and that the projections they contain are based on a number of significant assumptions. We have not independently verified this data or determined the reasonableness of such assumptions. In addition, in many cases we have made statements in this prospectus (and may make statements in any related prospectus supplement) regarding our industry and our position in the industry based on internal surveys, industry forecasts and market research, as well as our own experience. While these statements are believed to be reliable, they have not been independently verified.

ARCELORMITTAL

ArcelorMittal is the world’s largest and most global steel producer and a significant producer of iron ore and coal with production of 93.1 million tonnes of crude steel and, from own mines and strategic contracts, 77.0 million tonnes of iron ore and 7.70 million tonnes of coal in 2014. ArcelorMittal had sales of $79.3 billion and steel shipments of 85.1 million tonnes for the year ended December 31, 2014. As of December 31, 2014, ArcelorMittal had approximately 222,000 employees.

ArcelorMittal is the largest steel producer in North and South America, Europe and Africa, a significant steel producer in the CIS and has a smaller but growing presence in Asia.

ArcelorMittal has steel-making operations in 19 countries on four continents, including 56 integrated and mini-mill steel-making facilities. ArcelorMittal’s steel-making operations have a high degree of geographic diversification. Approximately 38% of its crude steel is produced in the Americas, approximately 47% is produced in Europe and approximately 15% is produced in other countries, such as Kazakhstan, South Africa and Ukraine. In addition, ArcelorMittal’s sales of steel products are spread over both developed and developing markets, which have different consumption characteristics. ArcelorMittal’s mining operations, present in North and South America, Africa, Europe and the CIS region, are integrated with its global steel-making facilities and are important producers of iron ore and coal in their own right.

ArcelorMittal produces a broad range of high-quality finished and semi-finished steel products. Specifically, ArcelorMittal produces flat steel products, including sheet and plate, and long steel products, including bars, rods and structural shapes. In addition, ArcelorMittal produces pipes and tubes for various applications. ArcelorMittal sells its steel products primarily in local markets and through its centralized marketing organization to a diverse range of customers in approximately 170 countries, including the automotive, appliance, engineering, construction and machinery industries. The Company also produces various types of mining products including iron ore lump, fines, concentrate and sinter feed, as well as coking, pulverized coal injection and thermal coal.

As a global steel producer, the Company is able to meet the needs of different markets. Steel consumption and product requirements clearly differ between developed markets and developing markets. Steel consumption in developed economies is weighted towards flat products and a higher value-added mix, while developing markets utilize a higher proportion of long products and commodity grades. To meet these diverse needs, the Company maintains a high degree of product diversification and seeks opportunities to increase the proportion of higher value-added products in its product mix.

USE OF PROCEEDS

Unless otherwise indicated in an accompanying prospectus supplement, the net proceeds from the sale of securities will be used to refinance existing indebtedness.

DESCRIPTION OF SENIOR DEBT SECURITIES

General

We may issue senior debt securities using this prospectus, which may include senior debt securities convertible into or exchangeable for our ordinary shares. As required by U.S. federal law for all bonds and notes of companies that are publicly offered, the senior debt securities that we may issue are governed by a contract between us and Wilmington Trust, National Association, as trustee, and Citibank, N.A., as securities administrator, called an indenture (as supplemented, herein the “senior indenture”).

The trustee’s main role under the senior indenture is that it can enforce your rights against us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described under “Events of Default” below. The securities administrator’s main role is to perform administrative duties for us, such as sending you interest payments and transferring your senior debt securities to a new buyer if you sell your senior debt securities. Both the trustee and the securities administrator may send you notices.

The senior indenture and its associated documents contain the full legal text governing the matters described in this section. The senior indenture and the senior debt securities are governed by New York law. A form of the senior indenture is an exhibit to our registration statement. See “Where You Can Find More Information” for information on how to obtain a copy. In connection with an issuance of senior debt securities, we may enter into one or more additional supplemental indentures with the trustee and the securities administrator, setting forth the specific terms of such senior debt securities.

In this section, references to “we,” “us” and “our” are to ArcelorMittal only and do not include our subsidiaries or affiliates.

References to “holders” mean those who have senior debt securities registered in their names on the books that ArcelorMittal or the Registrar maintain for this purpose, and not those who own beneficial interests in senior debt securities issued in book-entry form through The Depository Trust Company or in senior debt securities registered in street name. Owners of beneficial interests in the senior debt securities should refer to “Legal Ownership of Debt Securities.”

This section summarizes the material provisions of the senior indenture and certain senior debt securities that may be issued under the senior indenture. In particular, this section summarizes material terms of senior debt securities to be issued in fully registered, book-entry form without coupons, that will be unsecured and rank equally with all of our other existing and future unsecured and unsubordinated debt, bear interest at a fixed rate per annum, based upon a 360-day year consisting of twelve 30-day months. This section does not describe other types of senior debt securities that may be issued under the senior indenture, such as original issue discount securities, which are debt securities that are offered and sold at a substantial discount to their stated principal amount, or indexed securities or securities denominated in foreign currencies or currency units. Any other senior debt securities, and special U.S. federal income tax, accounting and other considerations applicable to such debt securities, would be described in the prospectus supplement relating to any such debt securities.

Because it is a summary, this section does not describe every aspect of the senior indenture or the senior debt securities. This summary is subject to and qualified in its entirety by reference to all the provisions of the senior indenture, including some of the terms used in the senior indenture. The senior indenture is also subject to the Trust Indenture Act of 1939. We describe the meaning for only the more important terms. Whenever we refer to particular sections or defined terms of the senior indenture in this prospectus or in the prospectus supplement, those sections or defined terms are incorporated by reference herein or in the prospectus supplement. This summary also is subject to and qualified by reference to the description of the particular terms of your series described in the prospectus supplement.

We may issue as many distinct series of senior debt securities under the senior indenture as we wish. Unless otherwise specified in a prospectus supplement, we may issue senior debt securities of the same series as an outstanding series of senior debt securities without the consent of holders of securities in the outstanding series. Any additional senior debt securities so issued will have the same terms as the existing senior debt securities of the same series in all respects (except for the issuance date, the date upon which interest begins accruing and, in some cases, the first interest payment on the new series, if any), so that such additional senior debt securities will be consolidated and form a single series with the existing senior debt securities of the same series; provided,

11

however, that unless such additional senior debt securities are issued under a separate CUSIP number, either such additional senior debt securities must be part of the same “issue” for U.S. federal income tax purposes or must be issued pursuant to a “qualified reopening” for U.S. federal income tax purposes.

In addition, the specific financial, legal and other terms particular to a series of senior debt securities are described in the prospectus supplement and the underwriting agreement relating to the series. Those terms may vary from the terms described here. Accordingly, this summary also is subject to and qualified by reference to the description of the terms of the series described in the prospectus supplement.

The prospectus supplement relating to a series of senior debt securities will describe the following terms of the series:

• the title of the series of senior debt securities;

• the authorized denominations in which senior debt securities of the series may be issued;

• the date or dates on which we will pay the principal of the series of senior debt securities (either at maturity or upon redemption);

• the rate or rates, per annum, at which the series of senior debt securities will bear interest and the date or dates from which that interest, if any, will accrue, and whether such interest shall be subject to any adjustment;

• the dates on which interest, if any, on the series of senior debt securities will be payable and the regular record dates for the interest payment dates;

• any provisions for redemption at the option of the holder;

• if other than the principal amount thereof, the portion of the principal amount of the senior debt securities of the series that will be payable upon any declaration of acceleration of maturity;

• the currency of payment of principal of, premium, if any, and interest on the series of senior debt securities and the manner of determining the equivalent amount in the currency of the United States of America, if applicable;

• any additional circumstances under which the series of senior debt securities will be redeemable at our option;

• any modifications or additional events of default, covenants or enforcement events applicable to the series of senior debt securities;

• the terms, if any, upon which the senior debt securities of the series may be convertible into or exchangeable for ordinary shares of ArcelorMittal;

• a discussion of any material U.S. federal income tax considerations; and

• any other special features of the series of senior debt securities.

Additional Amounts

The relevant prospectus supplement will specify the terms, if any, by which the Company or any successor entity, as the case may be, will pay additional amounts (“Additional Amounts”) as will result in receipt by the holders of such amounts as would have been received by the holders had no withholding or deduction been required by the Relevant Jurisdiction.

Redemption, Exchange and Purchase

Redemption

The prospectus supplement will state whether the senior debt securities are redeemable by us or subject to repayment at the holder’s option.

Exchange and Purchase

ArcelorMittal may at any time make offers to the holders to exchange their senior debt securities for other bonds or senior debt securities issued by us or any other Person. In addition, ArcelorMittal and any of our Subsidiaries or affiliates may at any time purchase senior debt securities in the open market or otherwise at any price.

12

Cancellation

All senior debt securities that are exchanged or purchased may either be held or retransferred or resold or be surrendered for cancellation and, if so surrendered, will, together with all senior debt securities redeemed by us, be cancelled immediately and accordingly may not be reissued or resold.

Consolidation, Merger, Conveyance or Transfer

So long as any of the senior debt securities are outstanding, ArcelorMittal will not consolidate with or merge into any other Person (excluding Persons controlled by one or more members of the Mittal Family) or convey or transfer substantially all of our properties and assets to any other Person (excluding Persons controlled by one or more members of the Mittal Family) unless thereafter:

(i) the Person formed by such consolidation or into which ArcelorMittal is merged, or the Person which acquired all or substantially all of our properties and assets, expressly assumes pursuant to a supplemental indenture the due and punctual payment of the principal of and interest on all the senior debt securities and the performance or observance of every covenant of the senior indenture on our part to be performed or observed (including, if such Person is not organized in or a resident of Luxembourg for tax purposes, substituting such Person’s jurisdiction of organization or residence for Luxembourg for tax purposes where applicable, including for the obligation to pay Additional Amounts);

(ii) immediately after giving effect to such transaction, no event of default has occurred and is continuing; and

(iii) the Person formed by such consolidation or into which ArcelorMittal is merged, or the Person which acquired all or substantially all of our properties and assets delivers to the trustee and the securities administrator an officer’s certificate signed by a duly authorized officer and an opinion of counsel, each stating that the consolidation, merger, conveyance or transfer and, if a supplemental indenture is required in connection with the transaction, the supplemental indenture comply with the senior indenture and that all conditions precedent in the senior indenture relating to the transaction have been complied with and, immediately after giving effect to such transaction, no event of default has occurred and is continuing, except that such certificate and opinion shall not be required in the event that any such consolidation, merger, conveyance or transfer is made by order of any court or tribunal having jurisdiction over us, our properties and our assets.

Negative Pledge

Unless otherwise specified in the relevant prospectus supplement, so long as any of the senior debt securities remain outstanding, we will not, and will not permit any Material Subsidiary to, create or permit to subsist any Security upon any of our Assets or their respective Assets, as the case may be, present or future, to secure any Relevant Indebtedness incurred or guaranteed by us or by any such Material Subsidiary (whether before or after the issue of the senior debt securities) other than Permitted Security, unless our obligations under the senior debt securities are (i) equally and ratably secured so as to rank pari passu with such Relevant Indebtedness or the guarantee thereof or (ii) benefit from any other Security or arrangement as is approved by the holders of a majority in aggregate principal amount of the senior debt securities of the affected series then outstanding.

Events of Default

Unless otherwise provided in the prospectus supplement for any series of senior debt securities, each of the following will be an event of default under the senior indenture:

(1) the default in any payment of principal or any premium on any senior debt security when due, whether at maturity, redemption or otherwise, continues for 15 days;

(2) the default in any payment of interest (if any) and Additional Amounts (if any), on any senior debt security when due, continues for 30 days;

(3) our failure to comply with our other obligations contained in the senior indenture and the default or breach continues for a period of 60 days or more after ArcelorMittal receives written notice from the trustee or the securities administrator as provided for in the senior indenture;

(4) our failure, or the failure of any Material Subsidiary, (a) to pay the principal of any indebtedness for borrowed money, including obligations evidenced by any mortgage, indenture, bond, debenture, note, guarantee

13

or other similar instruments on the scheduled or original date due (following the giving of such notice, if any, as required under the document governing such indebtedness and as extended by any applicable cure period) or (b) to observe or perform any agreement or condition relating to such indebtedness such that such indebtedness has come due prior to its stated maturity and such acceleration has not been cured, unless (in the case of clauses (a) and (b)) (i) the aggregate amount of such indebtedness is less than €100,000,000 or (ii) the question of whether such indebtedness is due has been disputed in good faith by appropriate proceedings and such dispute has not been finally adjudicated against us or the Material Subsidiary, as the case may be;

(5) certain events of bankruptcy or insolvency involving our company or a Material Subsidiary; and

(6) any other event of default provided in the relevant prospectus supplement for a series of senior debt securities.

Upon the occurrence and continuation of any event of default as provided for in the senior indenture, then in every such case the trustee or the holders of at least 25% in aggregate principal amount of the outstanding senior debt securities of the affected series may declare the principal amount of the outstanding senior debt securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the trustee if given by Holders). Upon any such declaration, which ArcelorMittal calls a declaration of acceleration, the senior debt securities of such series shall become due and payable immediately.

The holders of a majority in aggregate principal amount of the outstanding senior debt securities of the affected series may rescind and annul a declaration of acceleration if an amount has been paid to or deposited with the trustee sufficient to pay the amounts set forth in the applicable provisions of the senior indenture and all events of default with respect to the senior debt securities of such series, other than the failure to pay the principal and other amounts of senior debt securities of that series that have become due solely by such declaration of acceleration, have been cured or waived.

If an event of default occurs or if ArcelorMittal breaches any covenant or warranty under the senior indenture or the senior debt securities, the trustee may pursue any available remedy to enforce any provision of the senior debt securities or the senior indenture. The trustee may maintain a proceeding even if it does not possess any of the senior debt securities or does not produce any of them in the proceeding. A delay or omission by the trustee or any holder of a senior debt security in exercising any right or remedy accruing upon an event of default shall not impair the right or remedy or constitute a waiver of or acquiescence in the event of default. All remedies are cumulative to the extent permitted by law.

Except in case of an event of default of which a responsible officer of the trustee has actual knowledge, where the trustee has some special duties, the trustee and the securities administrator are not required to take any action under the senior indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This protection is called an indemnity. If reasonable indemnity is provided, the holders of a majority in principal amount of the outstanding senior debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other proceeding seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action the trustee may undertake under the senior indenture.

Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the senior debt securities you hold, the following must occur:

• You must give the trustee written notice at its Corporate Trust Office that an event of default has occurred and remains uncured.

• The holders of 25% in principal amount of all outstanding senior debt securities of the relevant series must make a written request that the trustee institute proceedings because of the event of default, and must offer reasonable indemnity to the trustee against the cost and other liabilities of instituting a proceeding and provide such written request to the Corporate Trust Office of the trustee.

• The trustee must have failed to institute proceedings for 60 days after receipt of the above notice, request and offer of indemnity.

• No direction inconsistent with such written request must have been given to the trustee during such 60-day period by holders of a majority in aggregate principal amount of all outstanding senior debt securities of the relevant series.

14

• The terms of the relevant series of senior debt securities do not prohibit such remedy to be sought by the trustee and/or the holders.

Nothing, however, will prevent an individual holder from bringing suit to enforce payment.

Street name and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and to make or cancel a declaration of acceleration.

ArcelorMittal will furnish to the securities administrator and the trustee every year a brief certification of an officer of our Company as to the Company’s compliance with the conditions and covenants of the senior indenture. In addition, the Company must notify the trustee and the securities administrator promptly upon the occurrence of any event of default and in any event within ten days after it becomes aware of the occurrence of an event of default.

Amendments and Waivers

The senior indenture may be amended or modified without the consent of any holder of senior debt securities in order, among other things:

• to cure any ambiguity, defect or inconsistency;

• to provide for the issuance of additional senior debt securities in accordance with the limitations set forth in the senior indenture as of the date thereof;

• to add to the covenants of the Company, for the benefit of holders of all or any series of senior debt securities or to surrender any power or right conferred upon the Company;

• to add or modify for the benefit of the holders of all or any series of senior debt securities any events of default;

• to provide for the assumption by a successor company of our obligations under the senior debt securities and the senior indenture in the case of a merger or consolidation or sale of all or substantially all of our assets;

• to comply with any requirements of the SEC in connection with qualifying the senior indenture under the Trust Indenture Act; or

• to correct or add any other provisions with respect to matters or questions arising under the senior indenture, provided that such action will not adversely affect the interests of the holders of the senior debt securities of any series in any material respect.

Modifications and amendments of the senior indenture may be made by us, the trustee and the securities administrator with the consent of the holders of a majority in principal amount of the senior debt securities of each affected series then outstanding under the senior indenture. In addition, the holders of a majority in aggregate principal amount of the outstanding senior debt securities of any series may waive any past default under the senior indenture affecting such series, except an uncured default in the payment of principal of or interest on such series of senior debt securities or an uncured default relating to a covenant or provision of the senior indenture that cannot be modified or amended without the consent of each affected holder.

Notwithstanding the above, without the consent of each holder of an outstanding senior debt security affected, no amendment may, among other things:

• modify the stated maturity of the senior debt securities or the dates on which interest is payable in respect of the senior debt securities;

• change the method in which amounts of payments of principal or any interest thereon is determined;

• reduce the principal amount of, or interest on, the senior debt securities;

• reduce the premium payable upon redemption;

• change the obligation of the Company to pay Additional Amounts,

• change the currency of payment of the senior debt securities;

• change any obligation of the Company to maintain an office or agency in the places and for the purposes specified in the senior indenture;

• impair the right of the holders of senior debt securities to institute suit for the enforcement of any payment on or after the date due;

15

• reduce the percentage in principal amount of the outstanding senior debt securities, the consent of whose holders is required for any modification of or waiver of compliance with any provision of the senior indenture or defaults under the indenture and their consequences; and

• modify the provisions of the senior indenture regarding the quorum required at any meeting of holders.

Special Rules for Action by Holders

When holders take any action under the senior indenture, such as giving a notice of an event of default, declaring an acceleration, approving any change or waiver or giving the trustee or the securities administrator an instruction, the Company will apply the following rules in accordance with the standard procedures of the depositary for so long as the securities are in global form.

Only Outstanding Senior Debt Securities are Eligible

Only holders of outstanding senior debt securities will be eligible to participate in any action by holders. Also, the Company will count only outstanding senior debt securities in determining whether the various percentage requirements for taking action have been met. For these purposes, a senior debt security will not be “outstanding” if it has been cancelled or if the Company has deposited or set aside, in trust for its holder, money for its payment or redemption; provided, however, that, for such purposes, senior debt securities held by the Company or any other obligor on the senior debt securities or any affiliates of the Company or any such obligor are not considered outstanding.

Determining Record Dates for Action by Holders

The Company will generally be entitled to set any day as a record date for the purpose of determining the holders that are entitled to take action under the senior indenture. In some limited circumstances, only the trustee or securities administrator will be entitled to set a record date for action by holders. If the Company, the trustee or securities administrator set a record date for an approval or other action to be taken by holders, that vote or action may be taken only by persons or entities who are holders on the record date and must be taken during the period that the Company specifies for this purpose, or that the trustee or the securities administrator specifies if it sets the record date. The Company, the trustee or the securities administrator, as applicable, may shorten or lengthen this period from time to time, but not beyond 90 days.

Satisfaction and Discharge

The senior indenture will be discharged and will cease to be of further effect as to all outstanding senior debt securities of any series issued thereunder, when (i) all senior debt securities of that series that have been authenticated, except lost, stolen or destroyed senior debt securities that have been replaced or paid and senior debt securities for whose payment money has theretofore been deposited in trust and thereafter repaid to us, have been delivered to the securities administrator for cancellation, or all senior debt securities of that series that have not been delivered to the securities administrator for cancellation have become due and payable by reason of the giving of a notice of redemption or otherwise or will become due and payable within one year and ArcelorMittal has irrevocably deposited or caused to be deposited with the securities administrator as trust funds in trust solely for the benefit of the holders, cash in U.S. dollars, non-callable U.S. government securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the senior debt securities of such series not delivered to the securities administrator for cancellation for principal and accrued interest and Additional Amounts (if any) to the date of maturity or redemption; (ii) ArcelorMittal has paid or caused to be paid all sums payable by us under the senior indenture with respect to such series; and (iii) ArcelorMittal has delivered irrevocable instructions to the securities administrator to apply the deposited money toward the payment of the senior debt securities of such series at maturity or on the redemption date, as the case may be.

In addition, ArcelorMittal must deliver a certificate signed by a duly authorized officer and an opinion of counsel that all conditions precedent to the satisfaction and discharge have been satisfied.

Defeasance and Covenant Defeasance

Unless a supplemental indenture for a series of senior debt securities provides otherwise, the senior indenture provides that ArcelorMittal may elect either (1) to defease and be discharged from any and all obligations with respect to any series of senior debt securities (except for, among other things, certain obligations

16

to register the transfer or exchange of such series of senior debt securities, to replace temporary or mutilated, destroyed, lost or stolen senior debt securities of such series, to maintain an office or agency with respect to the senior debt securities of such series and to hold moneys for payment in trust) (“legal defeasance”) or (2) to be released from our obligations to comply with certain covenants under the senior indenture, and any omission to comply with such obligations will not constitute a default (or event that is, or with the passage of time or the giving of notice or both would be, an event of default) or an event of default with respect to the senior debt securities of such series (“covenant defeasance”). Legal defeasance or covenant defeasance, as the case may be, will be conditioned upon, among other things, (A) the irrevocable deposit by us with the securities administrator, in trust, of an amount in U.S. dollars, or non-callable U.S. government securities, or both, applicable to the senior debt securities of such series which through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount that will be sufficient, in the opinion of an internationally recognized firm of independent public accountants as appointed by the Company (a copy of which shall be provided to the trustee), to pay the principal of, and interest (if any) and Additional Amounts (if any) on the outstanding senior debt securities of the relevant series on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the senior debt securities are being defeased to such stated date for payment or to a particular redemption date and (B) no event of default or default with respect to the senior debt securities of the series shall have occurred and be continuing on the date of such deposit.

To effect legal defeasance or covenant defeasance, ArcelorMittal will be required to deliver to the trustee and the securities administrator an opinion of counsel with respect to U.S. federal income tax matters confirming that the deposit and related defeasance will not cause the holders and beneficial owners of the senior debt securities of such series to recognize income, gain or loss for U.S. federal income tax purposes. If ArcelorMittal elects legal defeasance, that opinion of counsel must be based upon a ruling from the U.S. Internal Revenue Service or a change in law to that effect. To effect legal defeasance or covenant defeasance, no default of event of default may have occurred and be continuing on the date of deposit.

ArcelorMittal may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option.

Payment

Payments in respect of the senior debt securities will be made by the paying agent. Initially, Citibank, N.A., the securities administrator under the senior indenture, will act as paying agent and security registrar. The Company may appoint one or more co-registrars and one or more additional paying agents. The Company may change any paying agent or security registrar without notice to any holder. The Company or any of its subsidiaries may act in any such capacity.

Subject to any applicable abandoned property law, the securities administrator and the paying agent will distribute to the Company upon request any money held by them for the payment of principal of, premium or interest on the senior debt securities that remains unclaimed for two years, and, thereafter, holders entitled to the money must look to the Company for payment as general creditors.

Governing Law

The senior debt securities will be governed by and construed in accordance with the laws of the State of New York. For the avoidance of doubt, the provisions of article 86 to 94-8 of the Luxembourg law of August 10, 1915 on commercial companies, as amended, do not apply to the senior debt securities.

Consent to Jurisdiction

ArcelorMittal has irrevocably submitted to the non-exclusive jurisdiction of any New York State court or any U.S. federal court sitting in the Borough of Manhattan, The City of New York, in respect of any legal suit, action or proceeding arising out of or in relation to the senior indenture or the senior debt securities, and agreed that all claims in respect of such legal action or proceeding may be heard and determined in such New York State or U.S. federal court and will waive, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of any such action or proceeding in any such court.

Notices

Notices to the holders will be provided to the addresses that appear on the security register of the senior debt securities.

DESCRIPTION OF SUBORDINATED DEBT SECURITIES

General

We may issue subordinated debt securities using this prospectus, which may include subordinated debt securities convertible into or exchangeable for our ordinary shares. As required by U.S. federal law for all bonds and notes of companies that are publicly offered, the subordinated debt securities that we may issue are governed by a contract between us and Wilmington Trust, National Association, as trustee, and Citibank, N.A., as securities administrator, called an indenture (as supplemented, herein the “subordinated indenture”).

The trustee’s main role under the subordinated indenture is that it can enforce your rights against us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described under “Events of Default” below. The securities administrator’s main role is to perform administrative duties for us, such as sending you interest payments and transferring your subordinated debt securities to a new buyer if you sell your senior debt securities. Both the trustee and the securities administrator may send you notices.

The subordinated indenture and its associated documents contain the full legal text governing the matters described in this section. The subordinated indenture and the subordinated debt securities are governed by New York law (see “Governing Law” below). A form of the subordinated indenture is an exhibit to our registration statement. See “Where You Can Find More Information” for information on how to obtain a copy. In connection with an issuance of subordinated debt securities, we may enter into one or more additional supplemental indentures with the trustee and the securities administrator, setting forth the specific terms of such subordinated debt securities.

In this section, references to “we,” “us” and “our” are to ArcelorMittal only and do not include our subsidiaries or affiliates.

References to “holders” mean those who have subordinated debt securities registered in their names on the books that ArcelorMittal or the Registrar maintain for this purpose, and not those who own beneficial interests in subordinated debt securities issued in book-entry form through The Depository Trust Company or in subordinated debt securities registered in street name. Owners of beneficial interests in the subordinated debt securities should refer to “Legal Ownership of Debt Securities.”

This section summarizes the material provisions of the subordinated indenture and certain subordinated debt securities that may be issued under the subordinated indenture. In particular, this section summarizes material terms of subordinated debt securities to be issued in fully registered, book-entry form without coupons, and that will be unsecured and subordinated obligations of ArcelorMittal. This section does not describe other types of subordinated debt securities that may be issued under the indenture, such as original issue discount subordinated securities, which are subordinated debt securities that are offered and sold at a substantial discount to their stated principal amount, or indexed securities or securities denominated in foreign currencies or currency units. Any other subordinated debt securities, and special U.S. federal income tax, accounting and other considerations applicable to such subordinated debt securities, would be described in the prospectus supplement relating to any such subordinated debt securities.

Because it is a summary, this section does not describe every aspect of the subordinated indenture or the subordinated debt securities. This summary is subject to and qualified in its entirety by reference to all the provisions of the subordinated indenture, including some of the terms used in the subordinated indenture. The subordinated indenture is also subject to the Trust Indenture Act of 1939. We describe the meaning for only the more important terms. Whenever we refer to particular sections or defined terms of the subordinated indenture in this prospectus or in the prospectus supplement, those sections or defined terms are incorporated by reference herein or in the prospectus supplement. This summary also is subject to and qualified by reference to the description of the particular terms of your series described in the prospectus supplement.

We may issue as many distinct series of subordinated debt securities under the subordinated indenture as we wish. Unless otherwise specified in a prospectus supplement, we may issue subordinated debt securities of the same series as an outstanding series of subordinated debt securities without the consent of holders of subordinated debt securities in the outstanding series. Any additional subordinated debt securities so issued will have the same terms as the existing subordinated debt securities of the same series in all respects (except for the issuance date, the date upon which interest begins accruing and, in some cases, the first interest payment on the

21

new series, if any), so that such additional subordinated debt securities will be consolidated and form a single series with the existing subordinated debt securities of the same series; provided, however, that, with respect to subordinated debt securities that are treated as debt for U.S. federal income tax purposes, unless such additional subordinated debt securities are issued under a separate CUSIP number, either such additional subordinated debt securities must be part of the same “issue” for U.S. federal income tax purposes or must be issued pursuant to a “qualified reopening” for U.S. federal income tax purposes.

In addition, the specific financial, legal and other terms particular to a series of subordinated debt securities are described in the prospectus supplement and the underwriting agreement relating to the series. Those terms may vary from the terms described here. Accordingly, this summary also is subject to and qualified by reference to the description of the terms of the series described in the prospectus supplement.

The prospectus supplement relating to a series of subordinated debt securities will describe the following terms of the series:

• the title of the series of subordinated debt securities;

• the authorized denominations and aggregate principal amount of the series of subordinated debt securities;

• whether the subordinated debt securities of that series are dated securities, with a stated maturity or date fixed for redemption (and if applicable, the stated maturity or date fixed for redemption), or perpetual securities, with no stated maturity or date fixed for redemption;

• the subordination provisions applicable to the subordinated debt securities of that series and the ranking of such subordinated debt securities to other senior and subordinated debt securities of the Company;

• the rate or rates, per annum, at which the series of subordinated debt securities will bear interest and the date or dates from which that interest, if any, will accrue, and whether such interest shall be subject to any adjustment;

• the date or dates on which (or, if applicable, the range of dates within which) any payment of principal, interest or premium on the series of subordinated debt securities will be payable (or the manner of determining the same), and the record date for any such payment,

• if interest is payable, the interest rate or rates, or how the interest rate or rates may be determined;

• the terms and conditions, if any, under which interest or other payments may or will be deferred or cancelled;

• the terms and conditions of any mandatory or optional redemption or repayment of the subordinated debt securities of the series, including if applicable, notice requirements, legal and regulatory requirements, redemption or repayment dates, periods and prices or amounts;

• the currency in which the subordinated debt securities are denominated, and in which we will make payments, and the manner of determining the equivalent amount in the currency of the United States of America, if applicable;

• if other than the principal amount thereof, the amount, or how to determine the amount, that will be payable upon any declaration of acceleration of maturity or if redeemed before any stated maturity;

• the terms and conditions, if any, under which the Company may elect to vary the terms of the subordinated debt securities of the series;

• any mechanism to effect a temporary or permanent reduction in the principal amount outstanding of the subordinated debt securities of that series;

• whether the events of default described in this prospectus or any other events of default, defaults, enforcement events, solvency events or other events permitting remedies apply to the subordinated debt securities of the series, and the remedies available following the occurrence thereof;

• whether the subordinated debt securities of the series will be listed on a securities exchange;

• whether the covenant defeasance and covenant defeasance provisions apply to the subordinated debt securities of the series;

• the terms, if any, upon which the subordinated debt securities of the series may be convertible into or exchangeable for ordinary shares of ArcelorMittal;

• a discussion of any material U.S. federal income tax considerations; and

• any other special features of the series of subordinated debt securities.

22

Additional Amounts

The relevant prospectus supplement will specify the terms, if any, by which the Company or any successor entity, as the case may be, will pay additional amounts (“Additional Amounts”) as will result in receipt by the holders of such amounts as would have been received by the holders had no withholding or deduction been required by the Relevant Jurisdiction.

Redemption, Exchange and Purchase

Redemption

The prospectus supplement will state whether the subordinated debt securities are redeemable by us or subject to repayment at the holder’s option.

Exchange and Purchase

ArcelorMittal may at any time make offers to the holders to exchange their subordinated debt securities for other bonds or subordinated debt securities issued by us or any other Person. In addition, ArcelorMittal and any of our Subsidiaries or affiliates may at any time purchase subordinated debt securities in the open market or otherwise at any price.

Cancellation

All subordinated debt securities that are exchanged or purchased may either be held or retransferred or resold or be surrendered for cancellation and, if so surrendered, will, together with all subordinated debt securities redeemed by us, be cancelled immediately and accordingly may not be reissued or resold.

Consolidation, Merger, Conveyance or Transfer

So long as any of the subordinated debt securities are outstanding, ArcelorMittal will not consolidate with or merge into any other Person (excluding Persons controlled by one or more members of the Mittal Family) or convey or transfer substantially all of our properties and assets to any other Person (excluding Persons controlled by one or more members of the Mittal Family) unless thereafter:

(i) the Person formed by such consolidation or into which ArcelorMittal is merged, or the Person which acquired all or substantially all of our properties and assets, expressly assumes pursuant to a supplemental indenture the due and punctual payment of the principal of and interest on all the subordinated debt securities and the performance or observance of every covenant of the subordinated indenture on our part to be performed or observed (including, if such Person is not organized in or a resident of Luxembourg for tax purposes, substituting such Person’s jurisdiction of organization or residence for Luxembourg for tax purposes where applicable, including for the obligation to pay Additional Amounts);

(ii) immediately after giving effect to such transaction, no event of default, if any are applicable, has occurred and is continuing; and

(iii) the Person formed by such consolidation or into which ArcelorMittal is merged, or the Person which acquired all or substantially all of our properties and assets delivers to the trustee and securities administrator an officer’s certificate signed by a duly authorized officer and an opinion of counsel, each stating that the consolidation, merger, conveyance or transfer and, if a supplemental indenture is required in connection with the transaction, the supplemental indenture comply with the subordinated indenture and that all conditions precedent in the subordinated indenture relating to the transaction have been complied with and, immediately after giving effect to such transaction, no event of default, if any are applicable, has occurred and is continuing, except that such certificate and opinion shall not be required in the event that any such consolidation, merger, conveyance or transfer is made by order of any court or tribunal having jurisdiction over us, our properties and our assets.

Status of the Subordinated Debt Securities

The subordinated debt securities will constitute the direct, subordinated and unsecured obligations of the Company and will be subordinated in right of payment to the prior payment in full of all claims of “senior creditors” in respect of that series and rank pari passu with certain other subordinated obligations or guarantees thereof in respect of that series (if any), in each case as defined or identified in the applicable prospectus supplement, and in priority only to ordinary shares of the Company and any other securities, obligations or

23

guarantees thereof of the Company expressed to rank junior to the securities of that series in the applicable prospectus supplement. Investors should be aware that there are currently no limitations on the Company’s ability to issue or guarantee indebtedness that would constitute claims of “senior creditors.” Unless otherwise specified in the applicable prospectus supplement for a series, the subordinated debt securities will not have the benefit of any negative pledge covenant.

Default, Remedies and Waiver of Default

You will have special rights if an applicable “event of default” with respect to your subordinated debt securities occurs and is not cured, as described in this section.

Events of Default

Unless otherwise indicated in the prospectus supplement for a series of subordinated debt securities, the term “event of default” means any of the following:

(1) the default in any payment of principal or any premium on any subordinated debt security when due, whether at maturity, redemption or otherwise, continues for 15 days;

(2) the default in any payment of interest (if any) and Additional Amounts (if any), on any subordinated debt security when due, continues for 30 days;

(3) our failure to comply with our other obligations contained in the subordinated indenture and the default or breach continues for a period of 60 days or more after ArcelorMittal receives written notice from the trustee or the securities administrator as provided for in the subordinated indenture;

(4) certain events of bankruptcy or insolvency involving our company; and

(5) any other event of default provided in the relevant prospectus supplement for a series of subordinated debt securities.

Remedies if an Event of Default Occurs

Upon the occurrence and continuation of any applicable event of default with respect to a series of subordinated debt securities, then in every such case the trustee or the holders of at least 25% in aggregate principal amount of the outstanding subordinated debt securities of the affected series may declare the principal amount of the outstanding subordinated debt securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the trustee if given by Holders). Upon any such declaration, which ArcelorMittal calls a declaration of acceleration, the subordinated debt securities of such series shall become due and payable immediately.

The holders of a majority in aggregate principal amount of the outstanding subordinated debt securities of the affected series may rescind and annul a declaration of acceleration if an amount has been paid to or deposited with the trustee sufficient to pay the amounts set forth in the applicable provisions of the subordinated indenture and all events of default with respect to the subordinated debt securities of such series, other than the failure to pay the principal and other amounts of subordinated debt securities of that series that have become due solely by such declaration of acceleration, have been cured or waived.

If an event of default occurs or if ArcelorMittal breaches any covenant or warranty under the subordinated indenture or the subordinated debt securities, the trustee may pursue any available remedy to enforce any applicable provision of the subordinated debt securities or the subordinated indenture. The trustee may maintain a proceeding even if it does not possess any of the subordinated debt securities or does not produce any of them in the proceeding. A delay or omission by the trustee or any holder of a subordinated debt security in exercising any right or remedy accruing upon an event of default shall not impair the right or remedy or constitute a waiver of or acquiescence in the event of default. All remedies are cumulative to the extent permitted by law.

Except in case of an event of default of which a responsible officer of the trustee has actual knowledge, where the trustee has some special duties, the trustee and the securities administrator are not required to take any action under the subordinated indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This protection is called an indemnity. If reasonable indemnity is provided, the holders of a majority in principal amount of the outstanding subordinated debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other proceeding seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action the trustee may undertake under the subordinated indenture.

24

Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the subordinated debt securities you hold, the following must occur:

• You must give the trustee written notice at its Corporate Trust Office that an event of default has occurred and remains uncured.

• The holders of 25% in principal amount of all outstanding subordinated debt securities of the relevant series must make a written request that the trustee institute proceedings because of the event of default, and must offer reasonable indemnity to the trustee against the cost and other liabilities of instituting a proceeding and provide such written request to the Corporate Trust Office of the trustee.

• The trustee must have failed to institute proceedings for 60 days after receipt of the above notice, request and offer of indemnity.

• No direction inconsistent with such written request must have been given to the trustee during such 60-day period by holders of a majority in aggregate principal amount of all outstanding subordinated debt securities of the relevant series.

• The terms of the relevant series of subordinated debt securities do not prohibit such remedy to be sought by the trustee and/or the holders.

Nothing, however, will prevent an individual holder from bringing suit to enforce payment.

Street name and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and to make or cancel a declaration of acceleration.

ArcelorMittal will furnish to the securities administrator every year a brief certification of an officer of our Company as to the Company’s compliance with the conditions and covenants of the subordinated indenture. In addition, the Company must notify the trustee and the securities administrator promptly upon the occurrence of any event of default and in any event within ten days after it becomes aware of the occurrence of an event of default.

Amendments and Waivers

The subordinated indenture may be amended or modified without the consent of any holder of subordinated debt securities in order, among other things:

• to cure any ambiguity, defect or inconsistency;

• to provide for the issuance of additional subordinated debt securities in accordance with the limitations set forth in the subordinated indenture as of the date thereof;

• to add to the covenants of the Company, for the benefit of holders of all or any series of subordinated debt securities or to surrender any power or right conferred upon the Company;

• to add or modify for the benefit of the holders of all or any series of subordinated debt securities any events of default;

• to provide for the assumption by a successor company of our obligations under the subordinated debt securities and the subordinated indenture in the case of a merger or consolidation or sale of all or substantially all of our assets;

• to comply with any requirements of the SEC in connection with qualifying the subordinated indenture under the Trust Indenture Act; or

• to correct or add any other provisions with respect to matters or questions arising under the subordinated indenture, provided that such action will not adversely affect the interests of the holders of the subordinated debt securities of any series in any material respect.

In addition, the prospectus supplement for a particular series of subordinated debt securities may also specify if the Company has the right to materially vary the terms of a series of subordinated debt securities.

Modifications and amendments of the subordinated indenture may be made by us, the trustee and the securities administrator with the consent of the holders of a majority in principal amount of the subordinated debt securities of each affected series then outstanding under the subordinated indenture. In addition, the holders of a

25

majority in aggregate principal amount of the outstanding subordinated debt securities of any series may waive any past default under the subordinated indenture affecting such series, except an uncured default in the payment of principal of or interest on such series of subordinated debt securities or an uncured default relating to a covenant or provision of the subordinated indenture that cannot be modified or amended without the consent of each affected holder.

Notwithstanding the above and unless the prospectus supplement for the series of subordinated debt securities specifies otherwise, without the consent of each holder of an outstanding subordinated debt security affected, no amendment may, among other things:

• modify the stated maturity of the subordinated debt securities (if any) or the dates on which interest is payable in respect of the subordinated debt securities;

• change the method in which amounts of payments of principal or any interest thereon is determined;

• reduce the principal amount of, or interest on, the subordinated debt securities;

• reduce the premium payable upon redemption;

• change the obligation of the Company to pay Additional Amounts,

• change the currency of payment of the subordinated debt securities;

• change any obligation of the Company to maintain an office or agency in the places and for the purposes specified in the subordinated indenture;

• impair the right of the holders of subordinated debt securities to institute suit for the enforcement of any payment on or after the date due;

• reduce the percentage in principal amount of the outstanding subordinated debt securities, the consent of whose holders is required for any modification of or waiver of compliance with any provision of the subordinated indenture or defaults under the subordinated indenture and their consequences;

• modify the provisions of the subordinated indenture with respect to the subordination of the subordinated debt securities in a manner adverse to any holder; and

• modify the provisions of the subordinated indenture regarding the quorum required at any meeting of holders.

Special Rules for Action by Holders

When holders take any action under the subordinated indenture, such as giving a notice of an event of default, declaring an acceleration, approving any change or waiver or giving the trustee or the securities administrator an instruction, the Company will apply the following rules.

Only Outstanding Subordinated Debt Securities are Eligible

Only holders of outstanding subordinated debt securities will be eligible to participate in any action by holders. Also, the Company will count only outstanding subordinated debt securities in determining whether the various percentage requirements for taking action have been met. For these purposes, a subordinated debt security will not be “outstanding” if it has been cancelled or if the Company has deposited or set aside, in trust for its holder, money for its payment or redemption; provided, however, that, for such purposes, subordinated debt securities held by the Company or any other obligor on the subordinated debt securities or any affiliates of the Company or any such obligor are not considered outstanding.

Determining Record Dates for Action by Holders

The Company will generally be entitled to set any day as a record date for the purpose of determining the holders that are entitled to take action under the subordinated indenture. In some limited circumstances, only the trustee or securities administrator will be entitled to set a record date for action by holders. If the Company, the trustee or securities administrator set a record date for an approval or other action to be taken by holders, that vote or action may be taken only by persons or entities who are holders on the record date and must be taken during the period that the Company specifies for this purpose, or that the trustee or the securities administrator specifies if it sets the record date. The Company, the trustee or the securities administrator, as applicable, may shorten or lengthen this period from time to time, but not beyond 90 days.

26

Satisfaction and Discharge

The subordinated indenture will be discharged and will cease to be of further effect as to all outstanding subordinated debt securities of any series issued thereunder, when (i) all subordinated debt securities of that series that have been authenticated, except lost, stolen or destroyed subordinated debt securities that have been replaced or paid and subordinated debt securities for whose payment money has theretofore been deposited in trust and thereafter repaid to us, have been delivered to the securities administrator for cancellation, or all subordinated debt securities of that series that have not been delivered to the securities administrator for cancellation have become due and payable by reason of the giving of a notice of redemption or otherwise or will become due and payable within one year and ArcelorMittal has irrevocably deposited or caused to be deposited with the securities administrator as trust funds in trust solely for the benefit of the holders, cash in U.S. dollars, non-callable U.S. government securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the subordinated debt securities of such series not delivered to the securities administrator for cancellation for principal and accrued interest and Additional Amounts (if any) to the date of maturity or redemption; (ii) ArcelorMittal has paid or caused to be paid all sums payable by us under the subordinated indenture with respect to such series; and (iii) ArcelorMittal has delivered irrevocable instructions to the securities administrator to apply the deposited money toward the payment of the subordinated debt securities of such series at maturity or on the redemption date, as the case may be.

In addition, ArcelorMittal must deliver a certificate signed by a duly authorized officer and an opinion of counsel stating that all conditions precedent to the satisfaction and discharge have been satisfied.

Defeasance and Covenant Defeasance

Unless a supplemental indenture for a series of subordinated debt securities provides otherwise, the subordinated indenture provides that ArcelorMittal may elect either (1) to defease and be discharged from any and all obligations with respect to any series of subordinated debt securities (except for, among other things, certain obligations to register the transfer or exchange of such series of subordinated debt securities, to replace temporary or mutilated, destroyed, lost or stolen subordinated debt securities of such series, to maintain an office or agency with respect to the subordinated debt securities of such series and to hold moneys for payment in trust) (“legal defeasance”) or (2) to be released from our obligations to comply with certain covenants under the subordinated indenture, and any omission to comply with such obligations will not constitute a default (or event that is, or with the passage of time or the giving of notice or both would be, an event of default) or an event of default with respect to the subordinated debt securities of such series (“covenant defeasance”).

Legal defeasance or covenant defeasance, as the case may be, will be conditioned upon, among other things, (A) the irrevocable deposit by us with the securities administrator, in trust, of an amount in U.S. dollars, or non-callable U.S. government securities, or both, applicable to the subordinated debt securities of such series which through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount that will be sufficient, in the opinion of an internationally recognized firm of independent public accountants as appointed by the Company, to pay the principal of, and interest (if any) and Additional Amounts (if any) on the outstanding subordinated debt securities of the relevant series on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the subordinated debt securities are being defeased to such stated date for payment or to a particular redemption date and (B) no event of default or default with respect to the subordinated debt securities of the series shall have occurred and be continuing on the date of such deposit.

To effect legal defeasance or covenant defeasance, ArcelorMittal will be required to deliver to the trustee and the securities administrator an opinion of counsel with respect to U.S. federal income tax matters confirming that the deposit and related defeasance will not cause the holders and beneficial owners of the subordinated debt securities of such series to recognize income, gain or loss for U.S. federal income tax purposes. If ArcelorMittal elects legal defeasance, that opinion of counsel must be based upon a ruling from the U.S. Internal Revenue Service or a change in law to that effect. To effect legal defeasance or covenant defeasance, no default of event of default may have occurred and be continuing on the date of deposit.

ArcelorMittal may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option.

27

Payment

Payments in respect of the subordinated debt securities will be made by the paying agent. Initially, Citibank, N.A., the securities administrator under the subordinated indenture, will act as paying agent and security registrar. The Company may appoint one or more co-registrars and one or more additional paying agents. The Company may change any paying agent or Security registrar without notice to any holder. The Company or any of its subsidiaries may act in any such capacity.

Subject to any applicable abandoned property law, the securities administrator and the paying agent will distribute to the Company upon request any money held by them for the payment of principal of, premium or interest on the subordinated debt securities that remains unclaimed for two years, and, thereafter, holders entitled to the money must look to the Company for payment as general creditors.

Governing Law

The subordinated debt securities will be governed by and construed in accordance with the laws of the State of New York.

For the avoidance of doubt, the provisions of article 86 to 94-8 of the Luxembourg law of August 10, 1915 on commercial companies, as amended, do not apply to the subordinated debt securities.

Consent to Jurisdiction

ArcelorMittal has irrevocably submitted to the non-exclusive jurisdiction of any New York State court or any U.S. federal court sitting in the Borough of Manhattan, The City of New York, in respect of any legal suit, action or proceeding arising out of or in relation to the subordinated indenture or the subordinated debt securities, and agreed that all claims in respect of such legal action or proceeding may be heard and determined in such New York State or U.S. federal court and will waive, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of any such action or proceeding in any such court.

Notices

Notices to the holders will be provided to the addresses that appear on the security register of the subordinated debt securities.

29

LEGAL OWNERSHIP OF DEBT SECURITIES

Street Name and Other Indirect Holders

We generally will not recognize investors who hold debt securities in accounts at banks or brokers as legal Holders of securities. When we refer to the “Holders” of debt securities, we mean only the actual legal and (if applicable) record Holder of those debt securities. Holding securities in accounts at banks or brokers is called holding in “street name.” If you hold debt securities in street name, we will recognize only the bank or broker or the financial institution the bank or broker uses to hold its debt securities. These intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the debt securities, either because they agree to do so in their customer agreements or because they are legally required. If you hold debt securities in street name, you should check with your own institution to find out:

• how it handles securities payments and notices;

• whether it imposes fees or charges;

• how it would handle voting rights if it were ever required;

• whether and how you can instruct it to send you debt securities and, if the debt securities are in registered form, have them registered in your own name, so you can be a direct Holder as described below; and

• how it would pursue rights under the debt securities if there were a default or other event triggering the need for Holders to act to protect their interests.

Direct Holders

Our obligations, as well as the obligations of the Trustee and those of any third parties employed by us or the trustee, under the debt securities run only to persons who are registered as Holders of the securities. As noted above, we do not have obligations to you if you hold in street name or other indirect means, either because you choose to hold debt securities in that manner or because the debt securities are issued in the form of global securities as described below. For example, once we make payment to the registered Holder, we have no further responsibility for the payment even if that Holder is legally required to pass the payment along to you as a street name customer but does not do so.

Global Securities

What is a Global Security?

A global security is a special type of indirectly held security. Unless otherwise specified in the prospectus supplement, debt securities will be issued in the form of global securities in registered form. In this case, the ultimate beneficial owners can only be indirect holders as the global security will be registered in the name of a financial institution we select.

In this case, we require that the debt securities included in the global security not be transferred to the name of any other direct Holder unless the special circumstances described below occur. The financial institution that acts as the sole direct Holder of the global security is called the “depositary.” Any person wishing to own a debt security must do so indirectly by virtue of an account with a broker, bank or other financial institution that in turn has an account with the depositary.

Special Investor Considerations for Global Securities

As an indirect holder, an investor’s rights relating to a global security will be governed by the account rules of the investor’s financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize this type of investor as a Holder of securities and instead deal only with the depositary in whose name the global security is registered.

If you are an investor in debt securities that are issued only in the form of global securities, you should be aware that:

• You cannot have debt securities registered in your own name.

• You cannot receive physical certificates for your interest in the debt securities.

30

• You will be a street name Holder and must look to your own bank or broker for payments on the debt securities and protection of your legal rights relating to the debt securities, as explained earlier under “Street Name and Other Indirect Holders.”

• You may not be able to sell interests in the debt securities to some insurance companies and other institutions that are required by law to own their securities in the form of physical certificates.

• The depositary’s policies will govern payments, transfers, exchange and other matters relating to your interest in the global security. We and the trustee have no responsibility for any aspect of the depositary’s actions or for its records of ownership interests in the global security. We and the trustee also do not supervise the depositary in any way.

Special Situations in Which a Global Security Will Be Terminated

Upon the occurrence in respect of any global security of any series of any one or more of the following (i) the depository notifies the Company that it is unwilling or unable to continue as depository for such global security or if at any time such depository ceases to be a clearing agency registered under the Exchange Act and the Company notifies the securities administrator that it is unable to locate a qualified successor, (ii) the Company executes and delivers to the securities administrator a company order that such global security shall be so exchangeable and the transfer thereof so registrable or (iii) there shall have occurred and be continuing an event of default, with respect to the securities of such series, or such other conditions as provided in the indenture for such series, such global security may be exchanged for securities registered in the names of, and the transfer of such global security may be registered to, such persons (including persons other than the depository with respect to such series and its nominees) as such depository shall direct. After that exchange, the choice of whether to hold debt securities directly or in street name will be up to the investor. Investors must consult their own bank or brokers to find out how to have their interests in debt securities transferred to their own name so that they will be direct Holders. The rights of street name investors and direct Holders in the debt securities have been previously described in the subsections entitled “Street Name and Other Indirect Holders” and “Direct Holders” above.

31

CLEARANCE AND SETTLEMENT OF DEBT SECURITIES

Senior and subordinated debt securities we issue may be held through one or more international and domestic clearing systems. The clearing systems ArcelorMittal uses are the book-entry systems operated by The Depository Trust Company (“DTC”) in the United States, Clearstream Banking, société anonyme, in Luxembourg (“Clearstream”) and the Euroclear System, in Belgium (“Euroclear”). These systems have established electronic securities and payment, transfer, processing, depositary and custodial links among themselves and others, either directly or through custodians and depositaries. These links allow the debt securities to be issued, held and transferred among the clearing systems without the physical transfer of certificates.

Special procedures to facilitate clearance and settlement have been established among these clearing systems to trade the debt securities across borders in the secondary market. Where payments for the debt securities ArcelorMittal issues in global form is made in U.S. dollars, these procedures can be used for cross-market transfers and the debt securities are cleared and settled on a delivery against payment basis.

The policies of DTC, Clearstream and Euroclear will govern payments, transfers, exchanges and other matters relating to your interest in the debt securities held by them.

None of ArcelorMittal, nor the securities administrator or the trustee have any responsibility for any aspect of the actions of DTC, Clearstream or Euroclear or any of their direct or indirect participants. ArcelorMittal has no responsibility for any aspect of the records kept by DTC, Clearstream or Euroclear or any of their direct or indirect participants. ArcelorMittal also does not supervise these systems in any way.

DTC, Clearstream, Euroclear and their participants perform these clearance and settlement functions under agreements they have made with one another or with their customers. You should be aware that they are not obligated to perform these procedures and may modify them or discontinue them at any time.

The description of the clearing systems in this section reflects our understanding of the rules and procedures of DTC, Clearstream and Euroclear as they are currently in effect. Those systems could change their rules and procedures at any time.

DTC

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities deposited with it by its participants and facilitates the settlement of transactions among its participants in such securities through electronic computerized book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to DTC’s book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. According to DTC, the foregoing information with respect to DTC has been provided to the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind. The rules applicable to DTC participants are on file with the SEC.

Clearstream

Clearstream is a licensed bank organized as a société anonyme incorporated under the laws of Luxembourg and is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier).

Clearstream holds securities for its customers and facilitates the clearance and settlement of securities transactions between Clearstream customers through electronic book-entry changes in accounts of Clearstream customers, thus eliminating the need for physical movement of certificates. Clearstream provides to its

32

customers, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities, securities lending and borrowing and collateral management. Clearstream interfaces with domestic markets in a number of countries. Clearstream has established an electronic bridge with Euroclear Bank S.A./N.V., the operator of the Euroclear System, to facilitate settlement of trades between Clearstream and Euroclear.

As a registered bank in Luxembourg, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector. Clearstream customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies and clearing corporations. In the United States, Clearstream customers are limited to securities brokers and dealers and banks, and may include the underwriters for the debt securities. Other institutions that maintain a custodial relationship with a Clearstream customer may obtain indirect access to Clearstream. Clearstream is an indirect participant in DTC.

Distributions with respect to the debt securities held beneficially through Clearstream will be credited to cash accounts of Clearstream customers in accordance with its rules and procedures, to the extent received by Clearstream.

The Euroclear System

The Euroclear System was created in 1968 to hold securities for participants of the Euroclear System and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thus eliminating the need for physical movement of certificates and risk from lack of simultaneous transfers of securities and cash. Transactions may now be settled in many currencies, including United States dollars and Japanese Yen. The Euroclear System provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries generally similar to the arrangements for cross-market transfers with DTC described below.

The Euroclear System is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”), under contract with Euroclear Clearance System plc, a U.K. corporation (the “Euroclear Clearance System”). The Euroclear Operator conducts all operations, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Euroclear Clearance System. The Euroclear Clearance System establishes policy for the Euroclear System on behalf of Euroclear participants. Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to the Euroclear System is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly. Euroclear is an indirect participant in DTC.

The Euroclear Operator is a Belgian bank. The Belgian Banking Commission and the National Bank of Belgium regulate and examine the Euroclear Operator.

The Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System and applicable Belgian law govern securities clearance accounts and cash accounts with the Euroclear Operator. Specifically, these terms and conditions govern:

• transfers of securities and cash within the Euroclear System;

• withdrawal of securities and cash from the Euroclear System; and

• receipts of payments with respect to securities in the Euroclear System.

All securities in the Euroclear System are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the terms and conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding securities through Euroclear participants.

Distributions with respect to debt securities held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the Euroclear Terms and Conditions, to the extent received by the Euroclear Operator and by Euroclear.

33

Settlement

You will be required to make your initial payment for the debt securities in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be effected in DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (based on European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving debt securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to their respective U.S. depositaries.

Because of time-zone differences, credits of debt securities received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such debt securities settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of debt securities by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but generally will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of debt securities among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time.

Other Clearing Systems

We may choose any other clearing system for a particular series of securities. The clearance and settlement procedures for the clearing system we choose will be described in the applicable prospectus supplement.

DESCRIPTION OF ORDINARY SHARES

This prospectus may be used to offer our ordinary shares either alone or underlying debt securities convertible into or exchangeable for our ordinary shares.

Holders of our ordinary shares are entitled to certain rights and subject to certain conditions.

The description of the ordinary shares of ArcelorMittal is discussed in detail in the 2014 Form 20-F, including under “Item 10.A—Additional Information—Share Capital” and “Item 10.B—Additional Information—Memorandum and Articles of Association.”

35

TAX CONSIDERATIONS

A description of any material U.S. federal and Luxembourg income tax consequences of the purchase, ownership and disposition of securities will be provided in the applicable prospectus supplement.

36

PLAN OF DISTRIBUTION

We may sell the securities offered by this prospectus:

• through underwriters;

• through dealers;

• through agents; or

• directly to purchasers.

The prospectus supplement relating to any offering will identify or describe:

• any underwriters, dealers or agents;

• their compensation;

• the estimated net proceeds to us;

• the purchase price of the securities;

• the initial public offering price of the securities; and

• any exchange on which the securities will be listed, if applicable.

If we use underwriters in the sale, they will acquire securities for their own account and may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Unless we otherwise state in the prospectus supplement, various conditions to the underwriters’ obligation to purchase securities apply, and the underwriters will be obligated to purchase all of the securities contemplated in an offering if they purchase any of such securities. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

Dealers

If we use dealers in the sale, unless we otherwise indicate in the prospectus supplement, we will sell securities to the dealers as principals. The dealers may then resell the securities to the public at varying prices that the dealers may determine at the time of resale.

Agents and Direct Sales

We may sell securities directly or through agents that we designate. The prospectus supplement will name any agent involved in the offering and sale and state any commissions we will pay to that agent. Unless we indicate otherwise in the prospectus supplement, any agent is acting on a best efforts basis for the period of its appointment.

Contracts with Institutional Investors for Delayed Delivery

If we indicate in the prospectus supplement, we will authorize underwriters, dealers or agents to solicit offers from various institutional investors to purchase securities. In this case, payment and delivery will be made on a future date that the prospectus supplement specifies. The underwriters, dealers or agents may impose limitations on the minimum amount that the institutional investor can purchase. They may also impose limitations on the portion of the aggregate amount of the securities that they may sell. These institutional investors include:

• commercial and savings banks;

• insurance companies;

• pension funds;

• investment companies;

• educational and charitable institutions; and

• other similar institutions as we may approve.

37

The obligations of any of these purchasers pursuant to delayed delivery and payment arrangements will not be subject to any conditions. However, one exception applies. An institution’s purchase of the particular securities cannot at the time of delivery be prohibited under the laws of any jurisdiction that governs:

• the validity of the arrangements; or

• the performance by us or the institutional investor.

Indemnification

Agreements that we will enter into with underwriters, dealers or agents may entitle them to indemnification by us against various civil liabilities. These include liabilities under the Securities Act of 1933. The agreements may also entitle them to contribution for payments which they may be required to make as a result of these liabilities. Underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for, us in the ordinary course of business.

Market Making

In the event that we do not list securities of any series on a U.S. national securities exchange, various broker-dealers may make a market in the securities, but will have no obligation to do so, and may discontinue any market making at any time without notice. Consequently, it may be the case that no broker-dealer will make a market in securities of any series or that the liquidity of the trading market for the securities will be limited.

Expenses

The expenses of any offering of debt securities will be detailed in the relevant prospectus supplement.

38

VALIDITY OF THE SECURITIES

Unless otherwise specified in the prospectus supplement, the validity of the ordinary shares of ArcelorMittal and the due authorization of the issuance of the securities under Luxembourg law will be passed upon for ArcelorMittal by Elvinger, Hoss & Prussen, its Luxembourg counsel, and the validity of the debt securities under New York law will be passed upon for ArcelorMittal by Cleary Gottlieb Steen & Hamilton LLP, its United States counsel, and for the underwriters by Davis Polk & Wardwell LLP.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 8. Indemnification of Directors and Officers.

The Articles of Association of ArcelorMittal provide that ArcelorMittal will, to the broadest extent permitted by Luxembourg law, indemnify every director and every member of the Group Management Board as well as every former director or member of the Group Management Board for fees, costs and expenses reasonably incurred in the defense or resolution (including a settlement) of all legal actions or proceedings, whether civil, criminal or administrative, he or she has been involved in his or her role as former or current director or member of the Group Management Board of ArcelorMittal.

The right to indemnification does not exist in the case of gross negligence, fraud, fraudulent inducement, dishonesty or for a criminal offense, or if it is ultimately determined that the director or member of the Group Management Board has not acted honestly, in good faith and with the reasonable belief that he or she was acting in the best interests of ArcelorMittal.

Item 10. Undertakings.

(a) The undersigned registrant hereby undertakes:

1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the “Securities Act”);

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information set forth in the registration statement;

provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

2. That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

4. To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act need not be furnished, provided, that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act or Rule 3-19 of Regulation S-X if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that are incorporated by reference in the registration statement.

5. That, for the purpose of determining liability under the Securities Act to any purchaser,

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration

41

statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

6. That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

7. That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

8. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
