&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;&lt;i&gt;Legal&lt;/i&gt;&lt;/b&gt;&amp;#x2014;The Western Australia Office of State
Revenue (the &amp;#x201C;OSR&amp;#x201D;) continues to review their technical
position on the imposition of stamp duty on the transfer of Tronox
Incorporated&amp;#x2019;s shares related to Kerr-McGee&amp;#x2019;s
restructuring in 2002 and from the share transfer related to the
spinoff of Tronox Incorporated from Kerr-McGee in 2005. On
October&amp;#xA0;20, 2012, the OSR rendered its assessment of $5
million, comprised of a primary stamp duty liability of $3 million
and penalty tax of $2 million. The Company had accrued $3 million
at December&amp;#xA0;31, 2012, which was recorded in &amp;#x201C;Trade and
other payables&amp;#x201D; in the unaudited Condensed Consolidated
Balance Sheets. As required by law, the Company paid the entire
amount of the assessment in January 2013; however it has submitted
an objection to the interest penalty, setting out the reasons that
the Commissioner of State Revenue has erred in the imposition of
the interest penalty. The Company expects to resolve the matter by
the end of 2013.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;&lt;i&gt;Environmental Contingencies&lt;/i&gt;&lt;/b&gt;&amp;#x2014;In accordance
with ASC 450, &lt;i&gt;Contingencies&lt;/i&gt;, the Company recognizes a loss
and records an undiscounted liability when litigation has commenced
or a claim or an assessment has been asserted or, based on
available information, commencement of litigation or assertion of a
claim or assessment is probable, and the associated costs can be
estimated. It is not possible for the Company to reliably estimate
the amount and timing of all future expenditures related to
environmental matters because, among other reasons, environmental
laws and regulations, as well as enforcement policies and clean up
levels, are continually changing, and the outcome of court
proceedings, alternative dispute resolution proceedings (including
mediation) and discussions with regulatory agencies are inherently
uncertain.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px"&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company
believes that it has reserved adequately for the probable and
reasonably estimable costs of known contingencies. There is no
environmental litigation, claim or assessment that has been
asserted nor is there any probability of an assessment or a claim
for which the Company has not recorded a liability. However,
additions to the reserves may be required as additional information
is obtained that enables the Company to better estimate its
liabilities. The Company cannot reliably estimate the amount of
future additions to the reserves at this time. In certain
situations, reserves may be probable but not estimable.
Additionally, sites may be identified in the future where the
Company could have potential liability for environmental related
matters. If a site is identified, the Company will evaluate to
determine what reserve, if any, should be established.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;b&gt;&lt;i&gt;Other
Matters&lt;/i&gt;&lt;/b&gt;&amp;#x2014;From time to time, the Company may be party
to a number of legal and administrative proceedings involving
environmental and/or other matters in various courts or agencies.
These proceedings, individually and in the aggregate, may have a
material adverse effect on the Company. These proceedings may be
associated with facilities currently or previously owned, operated
or used by the Company and/or its predecessors, some of which may
include claims for personal injuries, property damages, cleanup
costs and other environmental matters. Current and former
operations of the Company may also involve management of regulated
materials, which are subject to various environmental laws and
regulations including the Comprehensive Environmental Response
Compensation and Liability Act (&amp;#x201C;CERCLA&amp;#x201D;), the Resource
Conservation and Recovery Act (the &amp;#x201C;RCRA&amp;#x201D;) or state
equivalents. Similar environmental laws and regulations and other
requirements exist in foreign countries in which the Company
operates.&lt;/font&gt;&lt;/p&gt;

rental commitments, primarily for buildings, land, equipment and
railcars under non-cancellable operating leases was $29 million for
2013, $27 million for 2014, $25 million for 2015, $23 million for
2016, $23 million for 2017 and $157 million thereafter. Total
rental expense related to operating leases was $8 million, $12
million, $1 million and $15 million, respectively, for the year
ended December&amp;#xA0;31, 2012, eleven months ended December&amp;#xA0;31,
2011, one month ended January&amp;#xA0;31, 2011 and year ended
December&amp;#xA0;31, 2010. Future minimum lease payments under capital
leases at December&amp;#xA0;31, 2012 were not significant. See Note

spinoff of Tronox Incorporated from Kerr-McGee in 2005. On
January&amp;#xA0;17, 2012, the OSR contacted the Company seeking
additional information related to the 2005 spinoff. In addition,
the OSR informed the Company that it has made a preliminary
determination that the Company was land rich at the time of the
2002 share transfers and, as a result, the Company may be liable
for stamp duty and penalties arising from that share transfer. The
OSR has not made an assessment at this time and continues
discussions with the Company and its legal advisors. The Company
has accrued stamp duty on the 2002 transaction in the amount of $3
million based upon its position that the Company was not land rich
at the time of the share transfers. The Company intends to exercise
all of its legal and administrative remedies in the event that the
OSR makes an assessment based upon its claim that it is land
rich.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;During 2011,
the outstanding legal disputes between the Company and RTI
Hamilton, Inc dating back to 2008 came to a close with the parties
reaching an agreement in principle. The agreement reflects a
compromise and settlement of disputed claims in complete accord and
satisfaction thereof. RTI Hamilton paid Tronox the sum of
$11&amp;#xA0;million, of which $1&amp;#xA0;million constituted payment for
capital costs incurred by the Company in relation to the agreement,
plus interest.&lt;/font&gt;&lt;/p&gt;
