    &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
    &lt;td&gt;&lt;b&gt;a)&lt;/b&gt;&amp;#160;In connection with a tax-advantaged lease financing arrangement sponsored by the
    French Government, we provided certain guarantees on December&amp;#160;30, 2004 on
    behalf of Vale Inco New Caledonia S.A.S. (VINC)&amp;#160;pursuant to which we guaranteed
    payments due from VINC of up to a maximum amount of US$100 (&amp;#8220;Maximum Amount&amp;#8221;) in connection with
    an indemnity. This guarantee was provided to BNP Paribas for the benefit of the tax
    investors of GniFi, the special purpose vehicle which owns a portion of the assets in our nickel
    cobalt processing plant in New Caledonia (&amp;#8220;Girardin Assets&amp;#8221;). We also provided an
    additional guarantee covering the payments due from VINC of (a)&amp;#160;amounts exceeding the Maximum
    Amount in connection with the indemnity and (b)&amp;#160;certain other amounts payable by VINC under a
    lease agreement covering the Girardin Assets. This guarantee was provided to
    BNP Paribas for the benefit of GniFi.&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;
    &lt;/div&gt;
    &lt;div style="margin-top: 6pt"&gt;
    &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;
    &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
    &lt;td width="3%" nowrap="nowrap" align="left"&gt;&amp;#160;&lt;/td&gt;
    &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
    &lt;td&gt;Another commitment incorporated in the tax&amp;#8211;advantaged lease financing arrangement was that
    the Girardin Assets would be substantially complete by December&amp;#160;31, 2009. In light of the delay
    in the start up of VINC processing facilities the December&amp;#160;31, 2009 substantially complete date
    was not met. Management proposed an extension to the substantially complete date from December
    31, 2009 to December&amp;#160;31, 2010. Both the French government authorities and the tax investors have
    agreed to this extension, though a signed waiver has not yet been received from the tax
    investors. The French tax authorities issued their signed extension on March&amp;#160;12, 2010.
    Accordingly the benefits of the financing structure are fully expected to be maintained and we
    anticipate that there will be no recapture of the tax advantages provided under this financing
    structure.&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;
    &lt;/div&gt;
    &lt;div style="margin-top: 6pt"&gt;
    &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;

    &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
    &lt;td&gt;In 2009, two new bank guarantees totaling US$58 (&amp;#8364;43) were established by us on behalf of VINC in
    favour of the South Province of New Caledonia in order to guarantee the performance of VINC with
    respect to certain environmental obligations in relation to the metallurgical plant and the Kwe
    West residue storage facility.&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;
    &lt;/div&gt;
    &lt;div style="margin-top: 6pt"&gt;
    &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;

    &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
    &lt;td&gt;Sumic Nickel Netherlands B.V. (&amp;#8220;Sumic&amp;#8221;), a 21% stockholder of VINC, has a put option to sell to
    us 25%, 50%, or 100% of the shares they own of VINC. The put option can be exercised if the
    defined cost of the initial nickel-cobalt development project, as measured by funding provided to
    VINC, in natural currencies and converted to U.S. dollars at specified rates of exchange, in the
    form of Girardin funding, shareholder loans and equity contributions by shareholders to VINC,
    exceeded $4.2&amp;#160;billion and an agreement cannot be reached on how to proceed with the project. On
    February&amp;#160;15, 2010, we formally amended our agreement with Sumic to increase the threshold to
    approximately $4.6&amp;#160;billion at specified rates of exchange.&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;
    &lt;/div&gt;
    &lt;div style="margin-top: 6pt"&gt;
    &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;
    &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
    &lt;td width="3%" nowrap="nowrap" align="left"&gt;&amp;#160;&lt;/td&gt;
    &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
    &lt;td&gt;We provided a guarantee covering certain termination payments due from VINC to the supplier under
    an electricity supply agreement (&amp;#8220;ESA&amp;#8221;) entered into in October&amp;#160;2004 for the VINC project. The
    amount of the termination payments guaranteed depends upon a number of factors, including whether
    any termination of the ESA is a result of a default by VINC and the date on which an early
    termination of the ESA were to occur. During the first quarter of 2010 the supply of electricity
    under the ESA to the project began, and the guaranteed amount now decreases over the life of the
    ESA from its maximum amount. As at March&amp;#160;31, 2010 the guarantee was US $180 (Euro 133).&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;
    &lt;/div&gt;
    &lt;div style="margin-top: 6pt"&gt;
    &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;

    &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
    &lt;td&gt;In February&amp;#160;2009, we and our subsidiary, Vale Inco Newfoundland and Labrador Limited (&amp;#8220;VINL&amp;#8221;),
    entered into a fourth amendment to the Voisey&amp;#8217;s Bay Development agreement with the Government of
    Newfoundland and Labrador, Canada, that permitted VINL to ship up to 55,000 metric tonnes of
    nickel concentrate from the Voisey&amp;#8217;s Bay area mines. As part of the agreement, VINL agreed to
    provide the Government of Newfoundland and Labrador financial assurance in the form of letters of
    credit each in the amount of US$16 (CAD$16) for each shipment of nickel concentrate shipped out
    of the province from January&amp;#160;1, 2009 to August&amp;#160;31, 2009. The amount of this financial assurance
    was US$110 (CAD$112) based on seven shipments of nickel concentrate and as of March&amp;#160;31, 2010,
    US$36 (CAD$36) remains outstanding.&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;
    &lt;/div&gt;
    &lt;div style="margin-top: 6pt"&gt;

    &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
    &lt;td&gt;As of March&amp;#160;31, 2010, there was an additional US$124 in letters of credit issued and outstanding
    pursuant to our syndicate revolving credit facility, as well as an additional US$41 of letters of
    credit and US$44 in bank guarantees that were issued and outstanding. These are associated with
    environmental reclamation and other operating associated items such as insurance, electricity
    commitments and import and export duties.&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;
    &lt;/div&gt;

    &lt;td&gt;&lt;b&gt;b)&lt;/b&gt;&amp;#160;We and our subsidiaries are defendants in numerous legal actions in the normal course of

    recognized are sufficient to cover probable losses in connection with such actions.&lt;/td&gt;

    &lt;td&gt;Tax &amp;#8211; tax-related actions principally comprise of challenges initiated by us, on certain taxes on
    revenues and uncertain tax positions. We continue to vigorously pursue our interests in all the
    above actions but recognize that we probably will incur some losses in the final instance, for
    which we have made provisions.&lt;/td&gt;

    March&amp;#160;31, 2009, totaled US$55, US$58, US$18, respectively. Provisions recognized in the
    three-month periods ended March&amp;#160;31, 2010, December&amp;#160;31, 2009 and March&amp;#160;31, 2009, totaled US$70,

    where in our opinion, and based on the advice of our legal counsel, the likelihood of loss is
    possible but not probable, in the total amount of US$4,344 at March&amp;#160;31, 2010, and for which no
    provision has been made (December&amp;#160;31, 2009 &amp;#8211; US$4,190).&lt;/td&gt;

    &lt;td&gt;&lt;b&gt;c)&lt;/b&gt;&amp;#160;At the time of our privatization in 1997, the Company issued debentures to its then-existing
    stockholders, including the Brazilian Government. The terms of the debentures, were set to ensure
    that the pre-privatization stockholders, including the Brazilian Government would participate in
    possible future financial benefits that could be obtained from exploiting certain mineral
    resources.&lt;/td&gt;

    &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
    &lt;td&gt;A total of 388,559,056 Debentures were issued at a par value of R $0.01 (one cent), whose value
    will be restated in accordance with the variation in the General Market Price Index (IGP-M), as
    set forth in the Issue Deed.&lt;/td&gt;

    &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
    &lt;td&gt;The debentures holders has the right to receive premiums, paid semiannually, equivalent to a
    percentage of net revenues from specific mine resources as set forth in the indenture.&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;

    &lt;td&gt;In April&amp;#160;2010 (subsequent period) we paid remuneration on these debentures of US $5.&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;

    &lt;td&gt;Changes in circumstances, law or technology may affect our estimates and we periodically review
    the amounts accrued and adjust them as necessary. Our accruals do not reflect unasserted claims
    because we are currently not aware of any such issues. Also the amounts provided are not reduced
    by any potential recoveries under cost sharing, insurance or indemnification arrangements because
    such recoveries are considered uncertain.&lt;/td&gt;
