VALE OVERSEAS LIMITED

US$            4.375% GUARANTEED NOTES DUE 2022

UNCONDITIONALLY GUARANTEED BY

VALE S.A.

         Vale Overseas Limited is offering US$            aggregate principal amount of its 4.375% Guaranteed Notes due 2022 (the "notes"). This offering is a reopening of Vale Overseas's US$1,000,000,000 4.375% Guaranteed Notes due 2022 issued on January 11, 2012, and the notes offered hereby will be consolidated with and form a single series with the original notes. Vale Overseas will pay interest on the notes semi-annually on January 11 and July 11 of each year, with the next payment being scheduled for July 11, 2012. Vale Overseas will pay additional amounts related to the deduction of certain withholding taxes in respect of certain payments on the notes.

         Vale Overseas may redeem the notes, in whole at any time or in part from time to time, at a redemption price equal to the greater of 100% of the principal amount of the notes to be redeemed and a "make-whole" amount described under "Description of the Notes—Optional Redemption" in this prospectus supplement, plus accrued and unpaid interest to the date of redemption. Upon the imposition of certain withholding taxes, Vale Overseas may also redeem the notes in whole, but not in part, at a price equal to 100% of their principal amount plus accrued interest to the redemption date.

         The notes will be unsecured obligations of Vale Overseas and will rank equally with Vale Overseas's unsecured senior indebtedness. Vale S.A. may assume the obligations of Vale Overseas under the notes under certain circumstances described under "Description of the Notes—Assumption by Guarantor of Issuer's Obligations under the Notes". The guaranty will rank equally in right of payment with all other unsecured and unsubordinated debt obligations of Vale S.A. The notes will be issued only in registered form in minimum denominations of US$2,000 and integral multiples of US$1,000 in excess thereof.

         Vale Overseas will apply to list the notes issued hereby on the New York Stock Exchange. The original notes are listed on the New York Stock Exchange.

         Investing in the notes involves risks that are described in the "Risk Factors" section beginning on page S-9 of this prospectus supplement.

         Neither the Securities and Exchange Commission ("SEC") nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

         The notes will be ready for delivery in book-entry form through The Depository Trust Company and its participants, including Euroclear and Clearstream, Luxembourg, on or about April     , 2012.

ENFORCEMENT OF CIVIL LIABILITIES

Brazil

        A final conclusive judgment for the payment of money rendered by any New York State or federal court sitting in New York City in respect of the notes would be recognized in the courts of Brazil and such courts would enforce such judgment without any retrial or reexamination of the merits of the original action only if such judgment has been ratified by the Brazilian Superior Court of Justice (Superior Tribunal de Justiça). This ratification is available only if:

•

the judgment fulfills all formalities required for its enforceability under the laws of the State of New York;



•

the judgment was issued by a competent court either after proper service of process on the parties, which service of process if made in Brazil must comply with Brazilian law, or after sufficient evidence of the parties' absence has been given, as established pursuant to applicable law;



•

the judgment is not subject to appeal;



•

the judgment has been authenticated by a Brazilian consulate in the State of New York;



•

the judgment has been translated into Portuguese by a certified sworn translator; and



•

the judgment is not against Brazilian public policy, good morals or national sovereignty.

        In addition:

•

Civil actions may be brought before Brazilian courts in connection with this prospectus supplement based on the federal securities laws of the United States, and Brazilian courts may enforce such liabilities in such actions against Vale (provided that the relevant provisions of the federal securities laws of the United States do not contravene Brazilian public policy, good morals or national sovereignty and provided further that Brazilian courts can assert jurisdiction over the particular action).



•

The ability of a judgment creditor to satisfy a judgment by attaching certain assets of the defendant is limited by Brazilian law. In addition, a Brazilian or foreign plaintiff who resides abroad or is abroad during the course of a suit in Brazil must post a bond to cover the legal fees and court expenses of the defendant, unless there are real estate assets in Brazil to assure payment thereof, except in case of execution actions or counterclaims as established under Article 836 of the Brazilian Code of Civil Procedure.

        Notwithstanding the foregoing, no assurance can be given that ratification would be obtained, that the process described above could be conducted in a timely manner or that a Brazilian court would enforce a monetary judgment for violation of the U.S. securities laws with respect to the notes.

Cayman Islands

        Vale Overseas has been advised by its Cayman Islands counsel, Walkers, that although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will, based on the principle that a judgment by a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given, recognize and enforce a foreign judgment of a court having jurisdiction over a defendant according to Cayman Islands conflict of law rules. To be so enforced the foreign judgment must be final and conclusive and for a liquidated sum not in respect of taxes or a fine or penalty or similar fiscal or revenue obligations or of a kind inconsistent with a Cayman Islands judgment in respect of the same matters or obtained in a manner, and is not of a kind the enforcement of which is, contrary to natural justice, statute or the

S-1

Table of Contents

public policy of the Cayman Islands. There is doubt, however, as to whether the courts of the Cayman Islands will:

•

recognize or enforce judgments of U.S. courts based on the civil liability provisions of the securities laws of the United States or any state thereof; or



•

in original actions brought in the Cayman Islands, impose liabilities upon the civil liability provisions of the securities laws of the United States or any state thereof, in each case, on the grounds that such provisions are penal in nature.

        A Cayman Islands court may stay proceedings if concurrent proceedings are being brought elsewhere.

RECENT DEVELOPMENTS

        For a discussion of our results of operations for the year ended December 31, 2011, see our report on Form 6-K furnished to the SEC on the date hereof, which is incorporated by reference in this prospectus supplement and other reports on Form 6-K listed under "Incorporation of Certain Documents by Reference".

RISK FACTORS

        Our annual report on Form 20-F for the year ended December 31, 2010, which is incorporated by reference in this prospectus supplement and the accompanying prospectus, includes extensive risk factors relating to our business. You should carefully consider those risks and the risks described below, as well as the other information included or incorporated by reference in this prospectus supplement or the accompanying prospectus, before making a decision to invest in the notes.

Risks Relating to the Notes

Vale's subsidiaries, affiliated companies and joint ventures are not obligated under the notes or the guaranty, and these companies' obligations to their own creditors will effectively rank ahead of Vale's obligations under the guaranty.

        Vale Overseas is the obligor under the notes and only its parent company, Vale, is obligated under the guaranty of the notes.

        Vale Overseas has no operations or assets, other than holding unsecured obligations from other Vale subsidiaries to repay loans. These other subsidiaries are not liable under the notes or the guaranty, and they may not have the ability to repay their loans from Vale Overseas.

        Vale conducts a significant amount of business through subsidiaries, affiliated companies and joint ventures, none of which are obligated under the notes or the guaranty. At December 31, 2011, the subsidiaries were responsible for approximately 26% of Vale's consolidated U.S. GAAP revenues from operations and approximately 9% of Vale's consolidated U.S. GAAP net cash flows provided by operating activities. The claims of any creditor of a subsidiary, affiliated company or joint venture of Vale would rank ahead of Vale's ability to receive dividends and other cash flows from these companies. As a result, claims of these creditors would rank ahead of Vale's ability to access cash from these companies in order to satisfy its obligations under the guaranty. In addition, these subsidiaries, affiliated companies and joint ventures may be restricted by their own loan agreements, governing instruments and other contracts from distributing cash to Vale to enable Vale to perform under its guaranty. At December 31, 2011, 11% of Vale's consolidated U.S. GAAP liabilities were owed by subsidiaries of Vale, which is the only obligor under the guaranty, meaning that the creditors under these liabilities would rank ahead of investors in the notes in the event of Vale's insolvency.

        The indenture governing the notes contains restrictions on the conduct of business by Vale Overseas and Vale, including limits on their ability to grant liens over their assets for the benefit of other creditors. These restrictions do not apply to Vale's other subsidiaries, affiliated companies and joint ventures, and these companies are not limited by the indenture in their ability to pledge their assets to other creditors.

There may not be a liquid trading market for the notes.

        The notes are an issuance of new securities with no established trading market. There can be no assurance that a liquid trading market for the notes will develop or, if one develops, that it will be maintained. If an active market for the notes does not develop, the price of the notes and the ability of a holder of notes to find a ready buyer will be adversely affected.

S-9

Table of Contents

We may not be able to make payments in U.S. dollars.

        In the past, the Brazilian economy has experienced balance of payment deficits and shortages in foreign exchange reserves, and the government has responded by restricting the ability of Brazilian or foreign persons or entities to convert reais into foreign currencies generally, and U.S. dollars in particular. The government may institute a restrictive exchange control policy in the future. Any restrictive exchange control policy could prevent or restrict our access to U.S. dollars, and consequently our ability to meet our U.S. dollar obligations and could also have a material adverse effect on our business, financial condition and results of operations. We cannot predict the impact of any such measures on the Brazilian economy.

In case of bankruptcy, we would be required to pay amounts only in reais.

        Any judgment obtained against Vale in the courts of Brazil in respect of any of Vale's payment obligations under the guaranty would be expressed in the real equivalent of the U.S. dollar amount of such sum. Accordingly, in case of bankruptcy, all credits held against Vale denominated in foreign currency would be converted into reais at the prevailing exchange rate on the date of declaration of bankruptcy by the judge. Further authorization by the Central Bank of Brazil would be required for the conversion of such real-denominated amount into foreign currency and for its remittance abroad.

Developments in other countries may affect prices for the notes.

        The market value of securities of Brazilian companies is, to varying degrees, affected by economic and market conditions in other countries. Although economic conditions in such countries may differ significantly from economic conditions in Brazil, investors' reactions to developments in any of these other countries may have an adverse effect on the market value of securities of Brazilian issuers. For example, in October 1997, prices of both Brazilian debt securities and Brazilian equity securities dropped substantially, precipitated by a sharp drop in the value of securities in Asian markets. The market value of the notes could be adversely affected by events elsewhere, especially in emerging market countries.

DESCRIPTION OF THE NOTES

        The following description of the particular terms of the notes supplements the description of the general terms set forth in the accompanying prospectus under the headings "Description of the Debt Securities" and "Description of the Guarantees". It is important for you to consider the information contained in the accompanying prospectus and this prospectus supplement before making a decision to invest in the notes. If any specific information regarding the notes in this prospectus supplement is inconsistent with the more general terms of the notes described in the prospectus, you should rely on the information contained in this prospectus supplement. In this description and in the related sections entitled "Description of the Debt Securities" and "Description of the Guarantees" in the accompanying prospectus, references to "Vale" mean Vale S.A. only and do not include Vale Overseas or any of Vale's other subsidiaries or affiliated companies. References to the notes include both the notes and the guaranty of the notes, except where the context indicates otherwise.

General

        Vale Overseas is offering US$            aggregate principal amount of its notes. The notes offered under this prospectus supplement represent a reopening of Vale Overseas's US$1,000,000,000 4.375% Guaranteed Notes due 2022 issued on January 11, 2012, and will be consolidated with and form a single series with those notes.

        Vale Overseas will issue the notes under an indenture dated as of November 21, 2006 and an amendment, dated on or about the delivery date of the notes, to the twelfth supplemental indenture dated as of January 11, 2012, each among Vale Overseas, as issuer, Vale, as guarantor, and The Bank of New York Mellon (as successor to The Bank of New York), as trustee. The notes will be issued only in fully registered form without coupons in minimum denominations of US$2,000 and integral multiples of US$1,000 in excess thereof. The notes will be unsecured and will rank equally with all of Vale Overseas's other existing and future unsecured and unsubordinated debt.

Principal and Interest

        The notes issued hereby will be fungible with the original notes, and will be consolidated with and form a single series under the indenture governing the original notes. The aggregate principal amount of the notes offered hereby and the original notes will be US$            . The notes will mature on January 11, 2022. The notes will bear interest at 4.375% per annum from January 11, 2012. Interest on the notes will be payable semi-annually on January 11 and July 11 of each year, beginning July 11, 2012, to the holders in whose names the notes are registered at the close of business on December 27 or June 26, immediately preceding the related interest payment date.

        Vale Overseas will pay interest on the notes on the interest payment dates stated above and at maturity. Each payment of interest due on an interest payment date or at maturity will include interest accrued from and including the last date to which interest has been paid or made available for payment, or from the issue date, if none has been paid or made available for payment, to but excluding the relevant payment date. Vale Overseas will compute interest on the notes on the basis of a 360-day year of twelve 30-day months.

        If any payment is due on the notes on a day that is not a business day, Vale Overseas will make the payment on the day that is the next business day. Payments postponed to the next business day in this situation will be treated under the indenture as if they were made on the original due date. Postponement of this kind will not result in a default under the notes or the indenture, and no interest will accrue on the postponed amount from the original due date to the next day that is a business day.

        Business day means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in New York City, São Paulo or Rio de Janeiro generally are authorized or obligated by law or executive order to close. With respect to notes in certificated form, the reference to

S-12

Table of Contents

business day will also mean a day on which banking institutions generally are open for business in the location of each office of a transfer agent, but only with respect to a payment or other action to occur at that office.

Guaranty

        Vale will irrevocably and unconditionally guarantee the full and punctual payment of principal, interest, additional amounts, if any, and all other amounts that may become due and payable in respect of the notes. If Vale Overseas fails to punctually pay any such amount, Vale will immediately pay the amount that is required to be paid and has not been paid. The guaranty will be unsecured and will rank equally with all of Vale's other existing and future unsecured and unsubordinated debt.

Payment of Additional Amounts

        Subject to the limitations and exceptions described in "Description of the Debt Securities—Payment of Additional Amounts" in the accompanying prospectus, Vale Overseas will pay such additional amounts as may be necessary to ensure that the net amounts receivable by holders after withholding or deduction for taxes will equal the amounts that would have been payable in the absence of such withholding or deduction. See "Description of the Debt Securities—Payment of Additional Amounts" in the accompanying prospectus.

Optional Redemption

        We will not be permitted to redeem the notes before their stated maturity, except as set forth below. The notes will not be entitled to the benefit of any sinking fund, meaning that we will not deposit money on a regular basis into any separate account to repay your notes. In addition, you will not be entitled to require us to repurchase your notes from you before the stated maturity.

Optional Redemption with "Make-Whole" Amount

        We will have the right at our option to redeem the notes, in whole at any time, or in part from time to time, prior to their maturity, on at least 30 days' but not more than 60 days' notice, at a redemption price equal to the greater of (1) 100% of the principal amount of the notes and (2) the sum of the present values of each remaining scheduled payment of principal and interest thereon (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 40 basis points (the "Make-Whole Amount"), plus accrued interest on the principal amount of the notes to the date of redemption.

        "Treasury Rate" means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (such price expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

        "Comparable Treasury Issue" means the U.S. Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the series of notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such notes.

        "Independent Investment Banker" means one of the Reference Treasury Dealers appointed by us.

        "Comparable Treasury Price" means, with respect to any redemption date (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest

S-13

---

Table of Contents

such Reference Treasury Dealer Quotation or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

        "Reference Treasury Dealer" means each of Citigroup Global Markets Inc., HSBC Securities (USA) Inc. and J.P. Morgan Securities LLC, or their affiliates, which are primary United States government securities dealers and one other leading primary U.S. government securities dealer in New York City reasonably designated by us; provided, however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer in New York City (a "Primary Treasury Dealer"), we will substitute therefor another Primary Treasury Dealer.

        "Reference Treasury Dealer Quotation" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 3:30 pm New York time on the third business day preceding such redemption date.

        On and after the redemption date, interest will cease to accrue on the notes or any portion of the notes called for redemption (unless we default in the payment of the redemption price and accrued interest). On or before the redemption date, we will deposit with the trustee money sufficient to pay the redemption price of and (unless the redemption date shall be an interest payment date) accrued interest to the redemption date on the notes to be redeemed on such date. If less than all of the notes of any series are to be redeemed, the notes to be redeemed shall be selected by the trustee by such method as the trustee shall deem fair and appropriate.

Optional Tax Redemption

        The notes are redeemable prior to maturity, upon the occurrence of certain changes in the tax laws of Brazil or the Cayman Islands as a result of which Vale Overseas or Vale becomes obligated to pay additional amounts on the notes in respect of withholding taxes at a rate in excess of 15%, in which case Vale Overseas may redeem the notes in whole but not in part at a redemption price equal to 100% of the principal amount of the notes plus accrued interest to the redemption date. See "Description of the Debt Securities—Optional Tax Redemption" in the accompanying prospectus.

Covenants

        Holders of the notes will benefit from certain covenants contained in the indenture and affecting the ability of Vale Overseas to incur debt and take other specified actions and the ability of Vale Overseas and Vale to incur liens and merge with other entities. You should read the information under the heading "Description of the Debt Securities—Certain Covenants" and "Description of the Debt Securities—Additional Terms of the Vale Overseas Debt Securities" in the accompanying prospectus.

Events of Default

        Holders of the notes will have special rights if an event of default occurs. You should read the information under the heading "Description of the Debt Securities—Events of Default" in the accompanying prospectus.

Further Issuances

        Vale Overseas reserves the right to issue, from time to time, without the consent of the holders of the notes, additional notes on terms and conditions identical to those of the notes, which additional notes shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the notes.

        Additional notes that are treated as a single class for non-tax purposes may be treated as separate issues for U.S. federal income tax purposes. In such case, such additional notes may be considered to

S-14

Table of Contents

have been issued with original issue discount, as defined in the U.S. Internal Revenue Code of 1986, as amended, and the U.S. Treasury Regulations promulgated thereunder, which may affect the market value of the notes, since such additional notes may not be distinguishable from the notes.

        Vale Overseas may also issue other securities under the indenture that have different terms from the notes. Likewise, Vale has the right, without the consent of the holders, to guarantee any such additional securities, to guarantee debt of its other subsidiaries, and to issue its own debt.

Assumption by Guarantor of Issuer's Obligations under the Notes

        Vale may assume, without the consent of the holders of the notes, the obligations of Vale Overseas for the due and punctual payment of the principal of (and premium, if any), interest on and any other payments with respect to the notes and for the performance of every applicable covenant of the relevant supplemental indenture pertaining to the notes on the part of Vale Overseas to be performed or observed, provided that (x) such obligations are expressly assumed by a supplemental indenture executed and delivered to the trustee; (y) immediately after giving effect to such transaction and treating any indebtedness which becomes an obligation of Vale as a result of such transaction as having been incurred by Vale at the time of such transaction, no event of default shall have occurred and be continuing; and (z) Vale has delivered to the trustee a certificate signed by two executive officers of Vale and an opinion of counsel of recognized standing, each stating that the assumption and supplemental indenture comply with the provisions of the applicable supplemental indenture pertaining to the notes. Following an assumption by Vale as described in this paragraph, Vale shall not assume the obligations of Vale Overseas described under "Description of the Debt Securities—Additional Terms of the Vale Overseas Debt Securities—Restrictive Covenants" in the accompanying prospectus, and the covenants of Vale relating to Vale Overseas described therein will cease to apply.

Governing Law

        The indenture and the notes will provide that they shall be governed by New York law.

Transfer Agent

        Vale Overseas may appoint one or more financial institutions to act as its transfer agents, at whose designated offices the notes in certificated form must be surrendered before payment is made at their maturity. Each of those offices is referred to as a transfer agent. The initial transfer agent is the trustee, at its corporate trust office. Vale Overseas may add, replace or terminate transfer agents from time to time, provided that if any notes are issued in certificated form, so long as such notes are outstanding, Vale Overseas will maintain a transfer agent in New York City. Vale Overseas must notify you of changes in the transfer agents pursuant to the provisions described under "Description of the Debt Securities—Notices" in the accompanying prospectus. If Vale Overseas issues notes in certificated form, holders of notes in certificated form will be able to transfer their notes, in whole or in part, by surrendering the notes, with a duly completed form of transfer, for registration of transfer at the office of the transfer agent. Vale Overseas will not charge any fee for the registration or transfer or exchange, except that Vale Overseas may require the payment of a sum sufficient to cover any applicable tax or other governmental charge payable in connection with the transfer.

Book-Entry Ownership, Denomination and Transfer Procedures for the Notes

        The following description of the operations and procedures of DTC, Euroclear and Clearstream, Luxembourg supplements the description contained under the heading "Legal Ownership of Debt Securities" in the accompanying prospectus and is provided to you solely as a matter of convenience. You should read this section in conjunction with the information provided in the accompanying prospectus. These operations and procedures are solely within the control of the respective settlement systems and are subject to change from time to time. Vale Overseas and Vale take no responsibility for

S-15

---

Table of Contents

these operations and procedures and urge you to contact the systems or their participants directly to discuss these matters.

        Vale Overseas and the trustee will make an application to DTC for acceptance in its book-entry settlement system of the notes, which will be in global form. The notes will be deposited with The Bank of New York Mellon, as custodian. The custodian and DTC will electronically record the principal amount of the notes held within the DTC system. Investors may hold such interests directly through DTC if they are participants in such system, or indirectly through organizations that are participants in DTC, such as Euroclear and Clearstream, Luxembourg.

        Ownership of beneficial interests in the notes will be limited to persons who have accounts with DTC, whom we refer to as DTC participants, or persons who hold interests through DTC participants. We expect that under procedures established by DTC:

•

upon deposit of the notes with DTC's custodian, DTC will credit portions of the principal amount of the notes to the accounts of the DTC participants designated by the underwriters, and



•

ownership of beneficial interests in the notes will be shown on, and transfer of ownership of those interests will be effected only through records maintained by DTC (with respect to interests of DTC participants) and the records of DTC participants (with respect to other owners of beneficial interests in the notes).

        As long as DTC or its nominee is the registered holder of the notes, DTC or its nominee will be considered the sole owner and holder of the notes for all purposes under the indenture and the notes. Except as described above, if you hold a book-entry interest in the notes in global form, you:

•

will not have notes registered in your name,



•

will not receive physical delivery of notes in certificated form, and



•

will not be considered the registered owner or holder of an interest in the notes under the indenture or the notes.

        As a result, each investor who owns a beneficial interest in the notes must rely on the procedures of DTC to exercise any rights of a holder under the indenture (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest).

        Payments of the principal of, and interest on, the notes registered in the name of DTC's nominee will be to the order of its nominee as the registered owner of such notes. It is expected that the nominee, upon receipt of any such payment, will immediately credit DTC participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the notes as shown on the records of DTC or the nominee. Vale Overseas also expects that payments by DTC participants to owners of beneficial interests in the notes held through such DTC participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such DTC participants. Neither Vale Overseas, the trustee nor any agent of the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of ownership interests in the notes or for maintaining, supervising or reviewing any records relating to such ownership interests.

        Because DTC or its nominee will be the only registered owner of the notes, Euroclear and Clearstream, Luxembourg will hold positions through their respective U.S. depositaries, which in turn will hold positions on the books of DTC.

        Cross-market transfers between DTC, on the one hand, and directly or indirectly through Euroclear or Clearstream, Luxembourg accountholders, on the other, will be effected through DTC in

S-16

---

Table of Contents

accordance with DTC rules on behalf of Euroclear or Clearstream, Luxembourg, as the case may be, by their respective U.S. depositaries. However, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, Luxembourg, as the case may be, by the counterparty in such system in accordance with its rules and procedures and within its established deadlines. Euroclear or Clearstream, Luxembourg, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving beneficial interests in the notes to or from DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream, Luxembourg accountholders may not deliver instructions directly to the U.S. depositaries for Euroclear or Clearstream, Luxembourg.

        On or after the Closing Date, transfers between accountholders in Euroclear and Clearstream, Luxembourg and transfers between participants in DTC will generally have a settlement date three business days after the trade date (T+3). The customary arrangements for delivery versus payment will apply to such transfers.

        Cross-market transfers between accountholders in Euroclear or Clearstream, Luxembourg and DTC participants will need to have an agreed settlement date between the parties to such transfer. However, as a result of time-zone differences, securities received in Euroclear or Clearstream, Luxembourg as a result of a transaction with a DTC participant will be credited to the relevant account at Euroclear or Clearstream, Luxembourg during the securities settlement processing day that is the fourth business day (T+4) following the DTC settlement date. Similarly, cash received in Euroclear or Clearstream, Luxembourg as a result of a sale of securities by or through a Euroclear or Clearstream, Luxembourg accountholder to a DTC participant will be available in the relevant Euroclear or Clearstream, Luxembourg cash account only on the fourth business day (T+4) following the DTC settlement date. In the case of cross-market transfers, settlement between Euroclear or Clearstream, Luxembourg accountholders and DTC participants cannot be made on a delivery versus payment basis. The securities will be delivered on a free delivery basis and arrangements for payment must be made separately.

        DTC has advised us that it will take any action permitted to be taken by a holder of notes (including, without limitation, the presentation of notes for exchange as described above) only at the direction of one or more participants in whose account with DTC interests in notes are credited and only in respect of such portion of the aggregate principal amount of the notes as to which such participant or participants has or have given such direction. However, in the circumstances described below, DTC will surrender the notes for exchange for individual definitive notes.

        DTC has advised us as follows: DTC is a limited purpose trust company organized under the laws of the State of New York, a "banking organization" under the laws of the State of New York, a member of the U.S. 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 Securities Exchange Act of 1934. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic computerized book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to DTC is available to others, such as banks, securities brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a DTC direct participant, either directly or indirectly.

Clearstream, Luxembourg is an indirect participant in DTC.

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

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 Euros. The Euroclear System provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries in a manner generally similar to the arrangements for cross-market transfers with DTC described above.

        The Euroclear System is operated by Euroclear Bank S.A./N.V. (the "Euroclear Operator"), under contract with Euroclear Clearance System, S.C., a Belgian cooperative corporation (the "Cooperative"). The Euroclear Operator conducts all operations, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative 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 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 notes 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.

        The foregoing information about DTC, Euroclear and Clearstream, Luxembourg has been provided by each of them for information purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

        Although DTC, Euroclear and Clearstream, Luxembourg have agreed to the foregoing procedures in order to facilitate transfers of beneficial interests in the notes among participants and accountholders of DTC, Euroclear and Clearstream, Luxembourg, they are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither Vale Overseas, nor the trustee nor any of the trustee's agents will have any responsibility for the performance by DTC, Euroclear or Clearstream, Luxembourg or their respective direct or indirect participants or accountholders of their respective obligations under the rules and procedures governing their operations.

        While a note in global form is lodged with DTC or the custodian, notes represented by individual definitive notes will not be eligible for clearing or settlement through DTC, Euroclear or Clearstream, Luxembourg.

Individual Definitive Notes

        Registration of title to notes in a name other than DTC or its nominee will not be permitted unless (i) DTC has notified us that it is unwilling or unable to continue as depositary for the notes in global form or the depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, at a time when DTC is required to be so registered in order to act as depositary, and, in each case, we do not or cannot appoint a successor depositary within 90 days or (ii) Vale Overseas decides in its sole discretion to allow some or all book-entry notes to be exchangeable for definitive notes in registered form. In such circumstances, Vale Overseas will cause sufficient individual definitive notes to be executed and delivered to the registrar for completion, authentication and dispatch to the relevant holders of notes. Payments with respect to definitive notes may be made through the transfer agent. A person having an interest in the notes in global form must provide the registrar with a written order containing instructions and such other information as the registrar and we may require to complete, execute and deliver such individual definitive notes.

        If Vale Overseas issues notes in certificated form, holders of notes in certificated form will be able to transfer their notes, in whole or in part, by surrendering the notes, with a duly completed form of transfer, for registration of transfer at the office of the transfer agent, The Bank of New York Mellon. Vale Overseas will not charge any fee for the registration or transfer or exchange, except that it may require the payment of a sum sufficient to cover any applicable tax or other governmental charge payable in connection with the transfer.

        All money paid by Vale Overseas to the paying agents for the payment of principal and interest on the notes which remains unclaimed at the end of two years after the amount is due to a holder will be repaid to Vale Overseas, and thereafter holders of notes in certificated form may look only to Vale Overseas and Vale for payment.

CERTAIN TAX CONSIDERATIONS

        The following discussion summarizes certain Cayman Islands, Brazilian, and U.S. federal income tax considerations that may be relevant to the ownership and disposition of the notes acquired in this offering for the original price. This summary does not describe all of the tax considerations that may be relevant to you or your situation, particularly if you are subject to special tax rules. You should consult your tax advisors about the tax consequences of holding the notes, including the relevance to your particular situation of the considerations discussed below, as well as of state, local and other tax laws.

Cayman Islands Tax Considerations

        The Cayman Islands currently have no exchange control restrictions and no income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax applicable to Vale Overseas or any holder of notes. Accordingly, payment of principal of and interest on the notes will not be subject to taxation in the Cayman Islands, no Cayman Islands withholding tax will be required on such payments to any holder of a note and gains derived from the sale of notes will not be subject to Cayman Islands capital gains tax. The Cayman Islands are not party to any double taxation treaties.

        Vale Overseas has received an undertaking from the Governor-in-Council of the Cayman Islands that, in accordance with section 6 of the Tax Concession Law (1999 Revision) of the Cayman Islands, for a period of 20 years from the date of the undertaking, no law which is enacted in the Cayman Islands imposing any tax to be levied on profits, income, gains or appreciations shall apply to Vale Overseas or its operations and, in addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable (i) on the shares, debentures or other obligations of Vale Overseas or (ii) by way of the withholding in whole or in part of a payment of dividend or other distribution of income or capital by Vale Overseas to its members or a payment of principal or interest or other sums due under a debenture or other obligation of Vale Overseas.

        No stamp duties or similar taxes or charges are payable under the laws of the Cayman Islands in respect of the execution and issue of the notes unless they are executed in or brought within (for example, for the purposes of enforcement) the jurisdiction of the Cayman Islands, in which case stamp duty of 0.25% of the face amount thereof may be payable on each note (up to a maximum of 250 Cayman Islands dollars ("CI$") (US$312.50)) unless stamp duty of CI$500 (US$625) has been paid in respect of the entire issue of notes.

        The above conversions of Cayman Islands dollars to U.S. dollars have been made on the basis of US$1.25 = CI$1.00.

Brazilian Tax Considerations

        The following discussion is a summary of the Brazilian tax considerations relating to an investment in the notes by an individual, a company, a trust, an organization or any other entity considered as resident or domiciled outside Brazil for tax purposes (a "Non-resident Holder"). The discussion contained herein is based on the tax laws of Brazil as in effect on the date hereof and is subject to possible changes in Brazilian law that may come into effect after such date.

        The information set forth below is intended to be a general discussion only and does not address all possible tax consequences relating to an investment in the notes. Prospective investors should consult their own tax advisers as to the consequences of purchasing the notes, including, without limitation, the consequences of the receipt of interest and the sale, redemption or repayment of the notes.

Table of Contents

Payments on the Notes Made by Vale Overseas

        Generally, a Non-resident Holder is taxed in Brazil only when income is derived from Brazilian sources or gains are realized on the sale or disposition of assets located in Brazil. Therefore, based on the fact that Vale Overseas is considered for tax purposes as a company domiciled abroad, any income (including interest and original issue discount) paid by Vale Overseas in respect of the notes in favor of Non-resident Holders will not be subject to any withholding or deduction in respect of Brazilian income tax or any other Brazilian taxes, duties, assessments or governmental charges, provided that such payments are made with funds held by Vale Overseas outside of Brazil.

Sale of the Notes

        In the event a Non-resident Holder sells the notes, such sale would not trigger any Brazilian tax consequences to the Non-resident Holder.

Other Brazilian Taxes

        Generally, there are no inheritance, gift, succession, stamp, or other similar taxes in Brazil with respect to the ownership, transfer, assignment or any other disposition of the notes by a Non-resident Holder, except for gift inheritance taxes imposed by some Brazilian states on gifts or bequests by individuals or entities not domiciled or residing in Brazil to individuals or entities domiciled or residing within such states.

Payments on the Notes Made by Vale

        If a payment is made to a Non-resident Holder from a Brazilian source in respect of the notes, such as by Vale, such payment may be subject, in whole or in part, to income tax withheld at source at a rate of up to 25%.

        In the event of withholding or deduction for or on account of Brazilian taxes, Vale Overseas and Vale will, subject to certain exceptions, pay additional amounts in respect of such withholding or deduction so that the net amount received by the holder after such withholding or deduction equals the amount of principal or interest that would have been received in the absence of such withholding or deduction. Please note, however, that Vale Overseas and Vale may redeem the notes in case any of them is obligated to pay additional amounts on the notes in respect of Brazilian or Cayman Islands withholding taxes at a rate in excess of 15%; see "Description of the Notes—Payment of Additional Amounts" in this prospectus supplement and "Description of the Debt Securities—Payment of Additional Amounts" in the accompanying prospectus.

United States Tax Considerations

        The following summary sets forth certain U.S. federal income tax consequences of the purchase, ownership and disposition of the notes. This summary is based upon existing U.S. federal income tax law as at the date of this offering memorandum, which is subject to change, possibly with retroactive effect, and different interpretations. This summary does not purport to discuss all aspects of U.S. federal income taxation which may be relevant to the particular circumstances of investors, and does not apply to investors subject to special tax rules, such as financial institutions, insurance companies, dealers in securities or currencies, traders in securities or currencies electing to mark their positions to market, regulated investment companies, U.S. expatriates, tax-exempt organizations, persons holding notes as part of a position in a "straddle" or as part of a hedging transaction, constructive sale or conversion transaction for U.S. tax purposes, investors whose functional currency is not the dollar or persons who own, directly or indirectly, 10 percent or more of our voting power. In addition, this summary does not discuss any foreign, state or local tax considerations, or any aspect of U.S. federal tax law other than income taxation. This summary only applies to holders that purchase notes at the initial issuance hereunder for an amount of cash equal to

S-21

Table of Contents

their issue price hereunder and that hold the notes as "capital assets" (generally, property held for investment) within the meaning of the U.S. Internal Revenue Code of 1986, as amended (the "Code"). Prospective investors should consult their own tax advisers regarding the U.S. federal, state and local, as well as foreign income and other, tax considerations of investing in the notes.

        For purposes of this summary, a U.S. Holder means a beneficial owner of notes who is (i) an individual that is a citizen or resident of the United States, (ii) a corporation created or organized in or under the laws of the United States, or any State thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source, (iv) a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or certain electing trusts that were in existence on August 20, 1996, and were treated as domestic trusts on August 19, 1996, or (v) otherwise subject to U.S. federal income tax on a net income basis.

        If an entity treated as a partnership for U.S. federal income tax purposes holds notes, the tax treatment of a partner will generally depend on the status of the partner and upon the activities of the partnership. Accordingly, partnerships that hold notes and partners in such partnerships should consult their tax advisers about the U.S. federal income tax consequences of purchasing, holding and disposing of notes.

Qualified Reopening

        We will treat the notes being offered pursuant to this prospectus supplement as having been issued in a "qualified reopening" for United States federal income tax purposes, and, except where specifically noted, the following discussion assumes such treatment will be respected. Consequently, the notes will be part of the same issue as the existing notes. U.S. Holders should be aware, however, that there is no assurance that the Internal Revenue Service (the "IRS") will agree with our intended treatment, and it is possible that the IRS will successfully assert that the notes being offered pursuant to this prospectus supplement were not issued in a "qualified reopening" for United States federal income tax purposes. U.S. Holders should consult their own tax advisors in this regard.

Pre-issuance Accrued Interest

        The initial offering price for the notes being offered pursuant to this prospectus supplement will include amounts attributable to interest accrued from January 11, 2012, which we call "pre-issuance accrued interest." Pre-issuance accrued interest will be included in the accrued interest to be paid on the notes on the first interest payment date after the issuance of the notes being offered pursuant to this prospectus supplement. In accordance with applicable United States Treasury regulations, for United States federal income tax purposes, we will treat the notes being offered pursuant to this prospectus supplement as having been purchased for a price that does not include any pre-issuance accrued interest. If the notes are so treated, the portion of the first stated interest payment equal to the pre-issuance accrued interest will be deemed to be a non-taxable return of pre-issuance accrued interest and, accordingly, will not be taxable as interest on the notes.

Payments of Stated Interest

        Payments of stated interest on the notes (including any additional amounts and withheld taxes, but excluding any pre-issuance accrued interest excluded from the purchase price of the notes, as discussed above under "—Pre-issuance Accrued Interest") generally will be taxable to a U.S. Holder as ordinary income at the time that such payments are received or accrued in accordance with the U.S. Holder's usual method of accounting for U.S. federal income tax purposes. Interest income in respect of the notes generally will constitute foreign-source income for purposes of computing the foreign tax credit allowable under the U.S. federal income tax laws. The limitation on foreign income taxes eligible for

S-22

Table of Contents

credit is calculated separately with respect to specific classes of income. In this regard, interest income in respect of the notes will constitute "passive category income" for most U.S. Holders for foreign tax credit purposes.

        Subject to generally applicable restrictions and conditions, if any foreign income taxes are withheld on interest payments on the notes, a U.S. Holder generally will be entitled to a foreign tax credit in respect of any such foreign income taxes. Alternatively, the U.S. Holder may deduct such taxes in computing taxable income provided that the U.S. Holder does not elect to claim a foreign tax credit for any foreign income taxes paid or accrued for the relevant taxable year. The rules regarding foreign tax credits and deduction of foreign income taxes are complex, so U.S. Holders should consult their own tax advisors regarding the availability of foreign tax credits or deductions in respect of foreign income taxes based on their particular circumstances.

Amortizable Premium

        The notes being offered pursuant to this prospectus supplement are being issued at a "premium" equal to the difference between their stated principal amount and their initial purchase price (excluding any amounts attributable to pre-issuance accrued interest, as discussed above under "—Pre-issuance Accrued Interest"). U.S. Holders generally may elect to amortize the premium over the remaining term of the notes on a constant yield method as an offset to interest when includible in income under the U.S. Holder's regular accounting method. If a U.S. Holder makes this election, the U.S. Holder will be required to reduce the Holder's adjusted tax basis in the notes by the amount of the premium amortized. If a U.S. Holder does not elect to amortize the premium, that premium will decrease the gain or increase the loss the Holder would otherwise recognize on disposition of the notes. An election to amortize premium on a constant yield method will also apply to all other taxable debt instruments held or subsequently acquired by the U.S. Holder on or after the first day of the first taxable year for which the election is made. Such an election may not be revoked without the consent of the IRS. U.S. Holders should consult their own tax advisors about this election.

Disposition of Notes

        A U.S. Holder will generally recognize taxable gain or loss upon the sale, exchange, redemption, retirement or other taxable disposition of a note in an amount equal to the difference between the amount realized upon such sale, exchange, retirement or other disposition (reduced by an amount attributable to accrued but unpaid stated interest, which is taxable in the manner described above under "—Payments of Stated Interest") and such U.S. Holder's adjusted tax basis in the note. A U.S. Holder's adjusted tax basis in a note will generally equal such U.S. Holder's initial investment in the note (less any amount attributable to pre-issuance accrued interest that is excluded from the purchase price of the note, as discussed above under "—Pre-issuance Accrued Interest"), reduced by any amortized premium. Such gain or loss will generally be long-term capital gain or loss if the note is held for more than one year. Certain U.S. Holders (including individuals) may be eligible for preferential tax rates in respect of long-term capital gain. The deductibility of capital losses by U.S. Holders is subject to limitations.

        If any foreign income tax is withheld on the sale or other taxable disposition of a note, the amount realized by a U.S. Holder will include the gross amount of the proceeds of that sale or other taxable disposition before deduction of such tax. Capital gain or loss, if any, realized by a U.S. Holder on the sale or other taxable disposition of the notes generally will be treated as U.S.-source gain or loss for U.S. foreign tax credit purposes. Consequently, in the case of a gain from the disposition of a note that is subject to foreign income tax, the U.S. Holder may not be able to benefit from a foreign tax credit for the tax unless the U.S. Holder can apply the credit against U.S. federal income tax payable on other income from foreign sources. Alternatively, the U.S. Holder may take a deduction for the foreign

Table of Contents

income tax if the U.S. Holder does not elect to claim a foreign tax credit for any foreign income taxes paid during the taxable year.

Assumption by Vale of Vale Overseas's Obligations Under the Notes

        In the event Vale assumes the obligations of Vale Overseas under the notes as described under "Description of the Notes—Assumption by Guarantor of Issuer's Obligations under the Notes", a U.S. Holder of the notes would be treated, for U.S. federal income tax purposes, as exchanging notes of Vale Overseas for notes of Vale, and would recognize taxable gain or loss equal to the difference between the U.S. Holder's tax basis in the notes of Vale Overseas and the fair market value of the notes of Vale. The U.S. Holder's initial tax basis in the notes of Vale, as well as the notes' "issue price" for U.S. federal income tax purposes, similarly would be equal to the fair market value of the notes at the time of the taxable exchange. The U.S. Holder's holding period for the notes of Vale for U.S. federal income tax purposes would also be restarted at the time of the taxable exchange. In the event that the notes of Vale have an issue price that is less than their stated principal amount by more than a de minimis amount (e.g., if the notes are trading at a more-than-de minimis discount to par at the time of the exchange), then the notes of Vale may be deemed to have been issued with "original issue discount" ("OID"), which a U.S. Holder would be required to accrue into taxable income over the remaining term of the note using a constant yield method. The result of accruing OID in this manner is that the U.S. Holder would be required to take amounts into taxable income before receiving cash in respect of those amounts. In addition, the tax basis of the U.S. Holder in the notes of Vale would be increased by any accrued OID. By contrast, if the issue price of the notes of Vale were in excess of their principal amount, a U.S. Holder would be treated as acquiring the notes of Vale at a premium equal to such excess, which a U.S. Holder could elect to amortize as an offset to interest income using a constant yield method. Such election, once made, generally applies to all bonds held or subsequently acquired by the U.S. Holder on or after the first taxable year to which the election applies and may not be revoked without the consent of the Internal Revenue Service. A U.S. Holder that elects to amortize such premium must reduce its adjusted tax basis in such note by the amount of the premium amortized during its holding period.

Backup Withholding and Information Reporting

        Payment on the notes and sales or redemption proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting and to backup withholding unless (i) the holder is an exempt recipient or (ii) in the case of backup withholding, the holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding.

        Any amounts withheld under the backup withholding rules from a payment to a holder will be refunded (or credited against such holder's U.S. federal income tax liability, if any), provided the required information is timely furnished to the U.S. Internal Revenue Service.

        The U.S. federal income tax discussion set forth above is included for general information only and may not be applicable depending on a holder's particular situation. Holders should consult their tax advisers with respect to the tax consequences to them of the beneficial ownership and disposition of the notes, including the tax consequences under state, local, foreign and other tax laws and the possible effects of changes in U.S. federal and other tax laws.

UNDERWRITING

        Vale Overseas intends to offer the notes through Barclays Capital Inc., Citigroup Global Markets Inc. and Deutsche Bank Securities Inc., the underwriters. Subject to the terms and conditions contained in a terms agreement between the underwriters, Vale Overseas and Vale, Vale Overseas has agreed to sell to the underwriters and the underwriters have agreed to purchase, severally and not jointly, from Vale Overseas, the principal amount of the notes listed below opposite each of their names.

        The underwriters have agreed to purchase all of the notes sold pursuant to the terms agreement if any of these notes are purchased. If the underwriters default, the terms agreement provides that the purchase agreement may be terminated.

        Vale Overseas and Vale have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

        Vale Overseas and Vale have agreed that Vale Overseas will not, during a period of 30 days from the date of this prospectus supplement, without the written consent of the underwriters, directly or indirectly, issue, sell, offer or contract to sell, grant any option or warrant for the sale of, or otherwise transfer or dispose of, any debt securities of Vale Overseas.

        The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the terms agreement, such as the receipt by the underwriters of officers' certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

        We expect that delivery of the notes will be made against payment therefor on or about April     , 2012, which will be the                    business day following the date of pricing of the notes (this settlement cycle being referred to as "T+    "). Under Rule 15c6-1 of the SEC under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade on the date of pricing or the next succeeding business day will be required, by virtue of the fact that the notes initially will settle in T+    , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes on the date of pricing or the next succeeding business day should consult their own advisor.

Commissions and Discounts

        The underwriters have advised Vale Overseas that they propose initially to offer the notes to the public at the public offering price on the cover page of this prospectus. After the initial public offering, the public offering price may be changed. The expenses of the offering, not including the underwriting discount, are estimated to be US$            and are payable by Vale Overseas. The underwriters may offer and sell the notes through certain of their affiliates.

Trading Market

        Application will be made to list the notes on the New York Stock Exchange in accordance with the rules and regulations of the New York Stock Exchange, subject to the satisfaction of its minimum listing standards. The original notes are listed on the New York Stock Exchange. Vale Overseas does not intend to apply for listing of the notes on any other securities exchange or for quotation of the notes on any automated dealer quotation system. The underwriters have advised us that they presently intend to make a market in the notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of any trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected.

Price Stabilization and Short Positions

        In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market price of the notes. Such transactions consist of bids or purchases to peg, fix or maintain the price of the notes. If the underwriters create a short position in the notes in connection with the offering, i.e., if they sell more notes than are on the cover page of this prospectus, the underwriters may reduce that short position by purchasing notes in the open market. Purchases of a security to stabilize the price or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases.

        Neither the underwriters nor we make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither the underwriters nor we make any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.
