Introduction


        WHEREAS,
as of the date hereof, Distributing is the common parent of an affiliated group of domestic corporations, including Tronox, which has elected to file consolidated federal income
tax returns; 


        WHEREAS,
the board of directors of Distributing has determined that it would be in the best interests of Distributing and its shareholders to separate the Tronox Business (as hereinafter
defined) from Distributing; 


        WHEREAS,
the boards of directors of Distributing and Kerr-McGee Worldwide Corporation have determined to contribute to Tronox Worldwide LLC certain entities engaged in the

the board of directors of Distributing expects to distribute (the "Distribution") all the outstanding shares of Class B common stock of Tronox to the shareholders of
Distributing; 


        WHEREAS,
prior to the Distribution, Tronox will issue to the public shares of Class A common stock of Tronox which, when issued, will constitute all of the outstanding shares of

        WHEREAS,
Distributing and Tronox intend that the Contribution qualify as a tax-free transfer under Sections 368(a)(1)(D) of the Internal Revenue Code of 1986, as amended (the
"Code"), and the Distribution qualify as a pro rata or non-pro rata tax-free distribution under Sections 355 and 368(a)(1)(D) of the Code; 


        WHEREAS,
it is appropriate and desirable to set forth the principles and responsibilities of the parties to this Agreement regarding (i) future adjustments with respect to Taxes,

implement the separation and Distribution; 


        NOW,
THEREFORE, in consideration of the mutual covenants and agreements contained herein, the parties hereby agree as follows: 


ARTICLE
I 


DEFINITIONS



        The
following terms shall have the following meanings (such meanings to apply equally to both the singular and the plural forms of the terms defined). All section references are to this
Agreement unless otherwise stated. 


        "Claims Court Litigation" means the litigation that is currently pending in the United States Court of Federal Claims, docket number

Cushing and Cleveland, Oklahoma. 


        "Claims Court Related Tax Adjustment" means, with respect to any Pre-Deconsolidation Period, and as computed separately for
each Tax, the net increase in each such Tax equal to the sum of all adjustments made after the Deconsolidation Date with respect to each such Tax for each such Pre-Deconsolidation Period

        "Claims Court Related Tax Benefit" means (i) 100% of any Tax refund received in the Claims Court Litigation or any Tax Contest
related to a Pre-Deconsolidation Period involving the same or similar factual and legal issues that are at issue in the Claims Court Litigation and (ii) any deduction, amortization,
exclusion from income, or other allowance (including a loss or reduced gain recognized upon a sale of an asset) that actually reduces in cash the amount of Tax that a member of the Tronox Group would
have been required to pay in a Post-Deconsolidation Period (or actually increases in cash the amount of any Tax refund to which a member of the Tronox Group would have been entitled in a
Post-Deconsolidation Period) in the absence of any basis increase resulting from a Final Determination in the Claims Court Litigation or in a Tax Contest related to a
Pre-Deconsolidation Period involving the same or similar factual and legal issues that are at issue in the Claims Court Litigation. 


        "Code" means the Internal Revenue of Code of 1986, as amended. 


        "Combined Tax" means any income or franchise Tax (whether measured by income or capital) payable to any state, local or foreign taxing
jurisdiction in which any member of the Tronox Group has filed or will file a Return with a member of the Distributing Group on an affiliated, consolidated, combined or unitary basis with
respect to such Tax. 


        "Combined Tax Return" means any Return with respect to a Combined Tax. 


        "Controlling Party" means, except as provided for in Section 4.06 hereof, Distributing or any other member of the Distributing
Group, or Tronox or any other member of the Tronox Group, as the case may be, that filed or, if no Return has been filed, was required to file, a Return that is subject to a Tax Contest, or any
successor and/or assign of any of the foregoing, provided that any Combined Tax Return filed by Kerr-McGee Worldwide Corporation with a
Taxing Authority in Mississippi shall be deemed to be a Return filed by Tronox and therefore Tronox shall be the Controlling Party with respect to any Tax Contest related to any such Return. For the
avoidance of doubt, with the exception of Returns filed in Mississippi and subject to Section 4.06 hereof, the company that actually filed any Federal Tax Return or Combined Tax Return (or any
successor or assign of such company) shall be the Controlling Party. 


        "Deconsolidation Date" means, for purposes of this Agreement, the first date on which Distributing and Tronox are no longer permitted to

net increase in each such Tax equal to the sum of all adjustments made pursuant to a Final Determination after the Deconsolidation Date with respect to each such Tax for each such taxable period or
portion thereof that are attributable to the Distributing Business; provided, however, that any
adjustment comprising a Restructuring Adjustment shall not be considered in determining the amount of any Distributing Tax Adjustment. 


        "Distributing Tax Benefit" means, with respect to any taxable period or portion thereof, and as computed separately for each Federal Tax
and Combined Tax, the net decrease in each Tax equal to the sum of all adjustments made pursuant to a Final Determination after the Deconsolidation Date with respect to each such Tax for each such
taxable period or portion thereof that are attributable to the Distributing Business; provided, however, that the amount of any Distributing Tax Benefit
shall not exceed 


2







 



the
amount that the actual Tax liability for the Tronox Group for the relevant taxable period is actually reduced by the adjustments made pursuant to such Final Determination;  provided further, however,
that any adjustment comprising a Restructuring Adjustment shall not be considered in determining the amount of any
Distributing Tax Benefit. For purposes of the foregoing, if an adjustment that would otherwise constitute a Distributing Tax Benefit is not considered a Distributing Tax Benefit because the Tax
liability of the Tronox Group is not actually reduced as a result of such adjustment, such adjustment shall be carried-forward and shall constitute a Distributing Tax Benefit at the time (and to the
extent) that the Tax liability of the Tronox Group is actually reduced as a result of such prior adjustment. For purposes of determining when an adjustment described in the preceding sentence actually
reduces the Tax liability of the Tronox Group, the Tronox Group shall be deemed to use all Tax Assets of the Tronox Group prior to such adjustment.

comparable provision of state, local or foreign law, (iii) a final disposition by any Taxing Authority of a claim for refund or (iv) any other written agreement relating to an adjustment
between any Taxing Authority and any Controlling Party the execution of which is final and prohibits such Taxing Authority or the Controlling Party from seeking any further legal or administrative
remedies with respect to such adjustment. 


        "Group" means the Distributing Group or the Tronox Group, as the context requires.

of any of the foregoing), as the case may be, to the extent (i) such person or a member of such person's Group is not a Controlling Party with respect to a Tax Contest and (ii) such
person or a member of such person's Group (A) may be liable for, or required to make, any indemnity payment, reimbursement, tax sharing payment or other payment pursuant to this Agreement with

increase in each such Tax equal to the sum of all adjustments made pursuant to a Final Determination with respect to each such Tax for each such taxable period or portion thereof that are attributable
to any Restructuring Transaction.

independent businesses other than the Distribution.

the foregoing, the Distributing Group's and the Tronox Group's relative contribution, if any, to an apportionment factor shall be determined by Distributing in good faith and in a manner consistent
with the past practices of Distributing and Tronox that have been used in determining apportionment factors. In the case of any jurisdiction in which Combined Taxes are calculated by first determining
the taxable income 


4







 



(or
loss) of each member of the combined group and then adding each separate company calculation to determine the group's total Combined Tax liability (a "Combined Add-Up State"), the
amount of the Tronox Combined Tax Liability with respect to such jurisdiction shall be calculated based on the product of the Tronox Group's income or loss and the separate apportionment factors
(property, payroll and sales) for each member of the Tronox Group, unless such amount is determined pursuant to another allocation method mandated by a specific jurisdiction. For purposes of the
preceding sentence, the apportionment factors shall be determined for each taxable period. 


        "Tronox Federal Tax Liability" means, with respect to any taxable year, the sum of the Tronox Group's Federal Tax liability and any
interest, penalties and other additions to Tax for such taxable year, computed as if the Tronox Group were not and never were part of the Distributing Consolidated Group, but rather were a separate
affiliated group of corporations filing a consolidated United States federal income tax return pursuant to Section 1501 of the Code; provided,  however,
 that transactions between members of the Tronox Group and members of the Distributing Group shall, so long as Tronox is a member of the
Distributing Consolidated Group, be reflected in accordance with the consolidated return regulations governing intercompany transactions. Such computation shall be made (i) without regard to
the income, deductions (including net operating loss and capital loss deductions) and credits in any year of any member of the Distributing Group, (ii) by taking into account any Tax Asset of
the Tronox Group in accordance with Section 3.02(d) hereof, (iii) with regard to net operating loss and capital loss carryforwards and carrybacks and minimum tax credits from earlier
years of the Tronox Group, but without regard to any such carryforwards from a Tax period (or portion thereof) ending on or before the date hereof and arising solely due to treating the Tronox Group
as if it were never part of the Distributing Consolidated Group, (iv) as though the highest rate of tax specified in Section 11(b) of the Code were the only rate set forth in that
section of the Code, (v) reflecting positions, elections and accounting methods used by Distributing in preparing the relevant Federal Tax Return for the Distributing Consolidated Group and
(vi) as though Tronox Worldwide LLC were a corporation rather than a disregarded entity for all taxable periods. For purposes of the foregoing, the Tronox Federal Tax Liability shall not
include any Restructuring Taxes.

subsidiaries, (B) KM (Luxembourg) Holdings Sarl and its direct and indirect subsidiaries, (C) Kerr-McGee B.V. and its subsidiary, (D) Kerr-McGee Finance
(Curacao) N.V., (E) KM Denmark International ApS and its direct and indirect subsidiaries and (F) the Tiwest JV Entities and (ii) after the Contribution, Tronox and each of its
direct and indirect subsidiaries and the Tiwest JV Entities. 


        "Tronox Tax Adjustment" means, with respect to any taxable period or portion thereof, and as computed separately for each Tax, the net
increase in each such Tax equal to the sum of all adjustments made pursuant to a Final Determination after the Deconsolidation Date with respect to each such Tax for each such taxable period or
portion thereof that are attributable to the Tronox Business; provided, however, that any adjustment
comprising a Restructuring Adjustment shall not be considered in determining the amount of any Tronox Tax Adjustment. 



        "Tronox Tax Benefit" means, with respect to any taxable period or portion thereof, and as computed separately for each Federal Tax and
Combined Tax, the net decrease in each such Tax equal to the sum of all adjustments made pursuant to a Final Determination after the Deconsolidation Date with respect to each such Tax for each such
taxable period or portion thereof that are attributable to the Tronox Business; provided, however, that the amount of any Tronox Tax Benefit shall not
exceed the amount that the actual Tax liability for the Distributing Consolidated Group for the relevant taxable period is actually reduced by the adjustments made pursuant to such Final
Determination; provided further, however, that any adjustment comprising a Restructuring Adjustment shall not be considered in determining the amount of
any Tronox Tax Benefit. For purposes of the foregoing, if an adjustment that would otherwise constitute a Tronox Tax Benefit is not considered a Tronox Tax Benefit because the Tax liability of the
Distributing Consolidated Group is not actually reduced as a result of such adjustment, such adjustment shall be carried-forward and shall constitute a Tronox Tax Benefit at the time (and to the
extent) that the Tax liability of the Distributing 


5







 



Consolidated
Group is actually reduced as a result of such prior adjustment. For purposes of determining when an adjustment described in the preceding sentence actually reduces the Tax liability of
the Distributing Consolidated Group, the Distributing Consolidated Group shall be deemed to use all Tax Assets of the Distributing Group prior to such adjustment.

II

of state, local or foreign law. If Distributing exercises its option to make such an election, each member of the Tronox Group shall provide a statement stating its consent to such election as

TAX
SHARING 


SECTION
3.01    Intentionally Omitted.    


SECTION
3.02    Tax Sharing.    


a)    Deconsolidation Payment.    Prior to the Deconsolidation Date, Tronox shall make a distribution to Distributing (the
"Estimated Tax Sharing Payment") in an amount equal to the sum of the Tronox Federal Tax Liability and the Tronox Combined Tax Liability for the portion of any taxable period that includes but does
not, with respect to Distributing or any other member of the Distributing Group, end on the Deconsolidation Date, in both cases as estimated by Distributing in its sole, good-faith
discretion, less any prior tax sharing payments made by any member of the Tronox Group to any member of the Distributing Group in respect of estimated Tax payments made for such taxable period. 


b)    Pro Forma Returns.    On the date that is five (5) business days prior to the due date for the Distributing
Consolidated Group's 2005 consolidated federal income tax return, including extensions, Distributing shall deliver to Tronox a pro forma federal income tax return (the "2005 Pro Forma Federal Tax
Return") of the Tronox Group reflecting the Tronox Federal Tax Liability for the portion of such taxable year in which members of the Tronox Group were included in the Distributing Consolidated Group.
On the date that is five (5) business days prior to the due date for each Combined Tax Return, including extensions, for any taxable period that includes, but does not, with respect to
Distributing or any member of the Distributing Group, end on the Deconsolidation Date, Distributing shall deliver to Tronox the relevant pro forma Combined Tax Return (each a "Pro Forma Combined Tax
Return" and together with the 2005 Pro Forma Federal Tax Return, the "Pro Forma Returns") of the Tronox Group reflecting the relevant Tronox Combined Tax Liability for the portion of such taxable
period in which members of the Tronox Group were included in the Distributing Consolidated Group with respect to such Combined Tax. Distributing shall prepare the Pro Forma Returns taking into account
elections, methods of accounting and positions with respect to specific items that are consistent with those to be made by Distributing for purposes of the Federal Tax Returns and Combined Tax
Returns. 


c)    True-Up Payment.    On or before the later of (i) the date Distributing (or whichever member of the
Distributing Group or the Tronox Group is responsible for filing such Return, if not Distributing) files its 


7







 



last
Combined Tax Return for each taxable period that includes but, with respect to Distributing or any other member of the Distributing Group, does not end on the Deconsolidation Date or
(ii) the date Distributing files its Federal Tax Return for the 2005 taxable year, Tronox shall pay to Distributing, or Distributing shall pay to Tronox, as appropriate, an amount equal to the
difference, if any, between (A) the aggregate of the Tronox Federal Tax Liability and the Tronox Combined Tax Liabilities reflected on the Pro Forma Returns and (B) the Estimated Tax
Sharing Payment. 


d)    Tax Assets.    If a Pro Forma Return reflects a Tax Asset of a member of the Tronox Group that may under applicable law be
used to reduce a Federal Tax or a Combined Tax of the Distributing Group for any Pre-Deconsolidation Period, Distributing shall pay to Tronox an amount equal to the actual Tax savings
produced by such Tronox Group Tax Asset at the time such Tax savings is realized by the Distributing Group. The amount of any such Tax savings shall be an amount of any refund actually received from a
Taxing Authority or the reduction in Taxes payable to a Taxing Authority as compared to the Taxes that would have been payable to a Taxing Authority in the absence of such Tronox Group Tax Asset. 


SECTION
3.03    Audit Payments.    


a)    Except
as provided in Section 3.03(c) hereof, Tronox shall be liable for, and shall indemnify and hold harmless, any member of the Distributing Group against any and all Tronox
Tax Adjustments for any Pre-Deconsolidation Period with respect to any Return of any member of the Distributing Group or the Tronox Group. Except as provided in Section 3.03(c)
hereof, Tronox shall be
entitled to receive, and shall be paid by Distributing, the amount of any Tronox Tax Benefit for any Pre-Deconsolidation Period with respect to any Return of any member of the Distributing
Group. 


b)    Distributing
shall be liable for, and shall indemnify and hold harmless, any member of the Tronox Group against any and all Distributing Tax Adjustments for any
Pre-Deconsolidation Period with respect to any Return of any member of the Distributing Group or the Tronox Group. Distributing shall be entitled to receive, and shall be paid by Tronox,
the amount of any Distributing Tax Benefits for any Pre-Deconsolidation Period with respect to any Return of any member of the Tronox Group. 



c)    Notwithstanding
Section 3.03(a) hereof, Distributing shall be liable for, and shall indemnify and hold harmless, any member of the Tronox Group against any and all Claims Court
Related Tax Adjustments. Notwithstanding Section 3.03(a) hereof, Distributing shall be entitled to receive, and, to the extent reflected on any Return of any member of the Tronox Group, shall
be paid by Tronox, the amount of any Claims Court Related Tax Benefits. For purposes of the preceding sentence as it applies to a Claims Court Related Tax Benefit described in clause (ii) of
the definition thereof, Tronox and the other members of the Tronox Group shall be deemed to use all other deductions, amortizations, exclusions from income or other allowances (to the extent that such
deductions, amortizations, exclusions from income or other allowances are entitled to be used under applicable law) prior to the use of any Claims Court Related Tax Benefit in respect of which Tronox
is required to pay Distributing hereunder. 


d)    Notwithstanding
anything herein to the contrary, for purposes of this Section 3.03, in the case of an adjustment for any Pre-Deconsolidation Period relating to any
state or local income or franchise Tax that is filed on a Combined Return (other than any Combined Tax Return filed in a Combined Add-Up State), the amount of any Tronox Tax Adjustment,
Tronox Tax Benefit, Distributing Tax Adjustment or Distributing Tax Benefit shall be determined on a Combined Return-by-Combined Return basis as follows: 



	(i)
	Audit
adjustments resulting in a net increase or net decrease in Tax liability (a "Tax Adjustment" or "Tax Benefit" respectively) shall be divided into two segments in
proportion to the Distributing Group's and the Tronox Group's relative contribution, if any, to the apportionment factor relevant to such Tax Adjustment or Tax Benefit, as the case may be, with each
such segment referred to as the "Distributing segment" and the "Tronox segment" for purposes of this Section 3.03(d). For purposes of this Section 3.03(d), each of the Distributing
Group's and the Tronox Group's relative contribution, if any, to an apportionment factor shall be determined (by 



8







 


Distributing
in good faith) (A) in a manner consistent with the past practices of Distributing and Tronox that have been used in determining apportionment factors and (B) by taking into
account and giving effect to all adjustments reflected in a Final Determination with respect to the relevant state or local income or franchise Tax for the taxable period or portion thereof that is at
issue. Accordingly, the apportionment factor allocation methodology will be applied to the Net Tax Liability Payable or Net Tax Refund Receivable (as defined below) in determining the total amount of
the Distributing segment and the Tronox segment. For purposes of the preceding sentence, "Net Tax Liability Payable" or "Net Tax Refund Receivable" shall mean the amount specified in the Final
Determination issued by the applicable state or local Taxing Authority after both giving effect to utilization of tax credits and net operating losses and taking into account any adjustments to
apportionment factors, federal taxable income and state modifications to federal taxable income. In the event that the Final Determination reflects both adjustments to the overall apportionment factor
and to state taxable income, the Distributing Group's and the Tronox Group's respective share, if any, of the Net Tax Liability Payable or Net Tax Refund Receivable shall be calculated as follows:
(I) first, by taking the revised state Tax liability as reflected in the Final Determination (i.e., the state tax liability as originally filed (including any prior revisions) modified by all
of the adjustments reflected in the Final Determination) and multiplying it by the respective Distributing Group's and Tronox Group's share of the overall apportionment factor as revised per such
Final Determination in order to determine the Distributing Group's and the Tronox Group's revised share of the state Tax liability (for purposes of this calculation, the Distributing Group's and the
Tronox Group's share of the revised overall apportionment factor will be a percentage determined by dividing each Group's revised individual factor by the revised overall apportionment factor);
(II) second, by taking the state Tax liability prior to revision by the Final Determination and multiplying it by the respective Distributing Group's and Tronox Group's share of the overall
apportionment factor prior to revision by such Final Determination in order to determine the Distributing Group's and the Tronox Group's share of the state Tax liability prior to the revisions made by
such Final Determination (for purposes of this calculation, the Distributing Group's and the Tronox Group's share of the overall apportionment factor prior to its revision by the Final Determination
will be a percentage determined by dividing each Group's individual factor prior to the Final Determination by the overall apportionment factor prior to its revision by the Final Determination); and
(III) third, the difference between items (I) and (II) shall constitute the Distributing Group's and/or the Tronox Group's share of the Net Tax Liability Payable or the Net Tax
Refund Receivable resulting from the adjustments made pursuant to the Final Determination (and thus determine the relative amounts of the Distributing segment or the Tronox segment). 



	(ii)
	The
Tronox Tax Adjustment or Tronox Tax Benefit shall be equal to the amount of the Tronox segment.



	(iii)
	The
Distributing Tax Adjustment or Distributing Tax Benefit shall be equal to the amount of the Distributing segment. 




SECTION
3.04    Restructuring Taxes and Adjustments.    The Distributing Group shall be liable for 100% of any Restructuring Tax and
any Restructuring Adjustment provided that the Distributing Group's aggregate liability for such Restructuring Taxes and Restructuring Adjustments shall not exceed $17 million (after which the
Tronox Group shall be liable for 100% of any Restructuring Tax and Restructuring Adjustment). If Tronox or another member of the Tronox Group is required under applicable law to pay any Restructuring
Tax or Restructuring Adjustment which is the liability of the Distributing Group pursuant to this Section 3.04, Tronox shall, upon written notice to Distributing, be entitled to a payment equal
to the portion of such Restructuring Tax or Restructuring Adjustment paid by Tronox or other member of the Tronox Group to the applicable Taxing Authority that is the liability of the Distributing
Group pursuant to this Section 3.04. If Distributing or another member of the Distributing Group is required under applicable 


9







 



law
to pay any Restructuring Tax or Restructuring Adjustment which is the liability of the Tronox Group pursuant to this Section 3.04, Distributing shall, upon written notice to Tronox, be
entitled to a payment equal to the portion of such Restructuring Tax or Restructuring Adjustment paid by Distributing or other member of the Distributing Group to the applicable Taxing Authority that
is the liability of the Tronox Group pursuant to this Section 3.04. 


SECTION
3.05    Non-Income Taxes.    In the case of any Return related to Taxes (other than income or franchise Taxes)
in which one or more members of the Distributing Group file with one or members of the Tronox Group (each such Return, a "Joint Return") with respect to a Pre-Deconsolidation Period, the
Distributing Group shall be liable for the Taxes reflected on any such Joint Return attributable to the Distributing Business and the Tronox Group shall be liable for the Taxes reflected on such Joint
Returns attributable to the Tronox Business. In the event that the portion of such Taxes attributable to a particular business cannot be determined, then the Distributing Group shall be liable for
such Taxes. 


SECTION
3.06    Deductions Related to Options and Restricted Stock.    For any and all taxable years ending on or after the
Deconsolidation Date, Tronox shall pay to Distributing the "deemed tax benefit" attributable to all deductions Tronox is entitled to claim after the Deconsolidation Date in respect of exercises of
compensatory stock options to acquire Distributing stock and the vesting of Distributing restricted stock (or dividends paid on Distributing restricted stock), in each case that are held by employees
(or former employees) of any member of the Tronox Group. For purposes of the foregoing, the "deemed tax benefit" referred to in the previous sentence shall conclusively be the total amount of the
available deduction for any such exercise or vesting multiplied by 36%. Tronox shall pay the "deemed tax benefit" amount to Distributing no later than the due date for filing Tronox's federal income
Tax Return for the year in which any such deduction is eligible to be claimed on such Return.

ARTICLE IV    
    
    TAX CONTESTS    



SECTION
4.01    Notification of Tax Contests.    The Controlling Party shall promptly notify all Interested Parties of
(a) the commencement of any Tax Contest pursuant to which such Interested Parties may be required to make or entitled to receive an indemnity payment, reimbursement, tax sharing payment or
other payment pursuant to this Agreement and (b) as required and specified in Section 4.04 hereof, any Final Determination made with respect to any Tax Contest pursuant to which such
Interested Parties may be required to make, or entitled to receive, any indemnity payment, reimbursement, tax sharing payment or other payment pursuant to this Agreement. The failure of a Controlling
Party to promptly notify any Interested Party as specified in the preceding sentence shall not relieve any such Interested Party of any liability and/or obligation which it may have to the Controlling
Party under this Agreement except to the extent that the Interested Party was actually materially prejudiced by such failure, and in no event shall such failure relieve the Interested Party from any
other liability or obligation which it may have to the Controlling Party. 


SECTION
4.02    Tax Contest Settlement Rights.    The Controlling Party shall have the sole right to contest, litigate, compromise
and settle any adjustment that is made or proposed in a Tax Contest without obtaining the prior consent of any Interested Party; provided,  however, that,
unless waived by the parties in writing, the Controlling Party shall, in connection with any proposed or assessed adjustment in a Tax
Contest for which an Interested Party may be required to make, or entitled to receive, an indemnity payment, reimbursement, tax sharing payment or other payment pursuant to this Agreement
(a) keep all Interested Parties informed in a timely manner of all actions taken or proposed to be taken by the Controlling Party and (b) timely provide all such Interested Parties with
copies of any correspondence or filings submitted to any Taxing Authority or judicial authority, in each case in connection with any contest, litigation, compromise or settlement relating to any such
adjustment in a Tax Contest. The failure of a Controlling Party to take any action as specified in the preceding sentence with respect to an Interested Party shall not relieve any such Interested
Party of any liability and/or obligation which it may have to such Controlling Party under this Agreement except to the extent that the Interested Party was actually materially prejudiced by such
failure, and in no event shall such failure relieve the Interested Party from any other liability or obligation which it may have to such Controlling Party. The Controlling Party may, at its sole
discretion, take into account any suggestions made by an Interested Party with respect to such contest, litigation, compromise or settlement of any adjustment in a Tax Contest. All costs of any Tax
Contest shall be borne by the Controlling Party; provided, however, that (x) any costs related to
an Interested Party's attendance at any meeting with a Taxing Authority or hearing or proceeding before any judicial authority pursuant to Section 4.03 hereof and (y) the costs of any
legal or other representatives retained by an Interested Party in connection with any Tax Contest that is subject to the provisions of this Agreement shall, in each case, be borne by such Interested
Party. 


SECTION
4.03    Tax Contest Participation.    Unless waived by the parties in writing, the Controlling Party shall provide an
Interested Party with written notice reasonably in advance of, and such Interested Party shall have the right to attend, any formally scheduled meetings with Taxing Authorities or hearings or
proceedings before any judicial authorities in connection with any contest, litigation, compromise or settlement of any proposed or assessed adjustment that is the subject of any Tax Contest pursuant
to which such Interested Party may be required to make, or entitled to receive, an indemnity payment, reimbursement, tax sharing payment or other payment pursuant to this Agreement. In addition,
unless waived by the parties in writing, the Controlling Party shall provide each such Interested Party with draft copies of any correspondence or filings to be submitted to any Taxing Authority or
judicial authority with respect to such adjustments for such Interested Party's review and comment. The Controlling Party shall provide such draft copies reasonably in advance of the date that they
are to be submitted to the Taxing Authority or judicial authority and the Interested Party shall provide comments, if any, with respect thereto 


11







 



within
a reasonable time before such submission. The failure of a Controlling Party to provide any notice, correspondence or filing as specified in this Section 4.03 to an Interested Party
shall not relieve any such Interested Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Interested Party was
actually materially prejudiced by such failure, and in no event shall such failure relieve the Interested Party from any other liability or obligation which it may have to the Controlling Party. 



SECTION
4.04    Tax Contest Waiver.    


a)    The
Controlling Party shall promptly provide written notice (the "Controlling Party Notice"), sent postage prepaid by United States mail, certified mail, return receipt requested, to
all Interested Parties in a Tax Contest (i) that a Final Determination has been made with respect to such Tax Contest and (ii) enumerating the amount of (A) if the Interested
Party is Distributing or any member of the Distributing Group, the Distributing Tax Adjustment or Distributing Tax Benefit or (B) if the Interested Party is Tronox or any member of the Tronox
Group, the Tronox Tax Adjustment or Tronox Tax Benefit. 


b)    Within
ninety (90) days after an Interested Party receives the notice described in Section 4.04(a) hereof from the Controlling Party, such Interested Party shall execute
a written statement giving notice to the Controlling Party (i) that the Interested Party agrees with the computations set forth in the Controlling Party Notice except with respect to those
adjustments computations that, in the good faith judgment of the Interested Party, it disagrees with and has specifically enumerated its disagreement with, including the amount of such disagreement,
in the statement (each such disagreed computation hereinafter referred to as a "Disputed Adjustment") and (ii) that the Interested Party thereby waives its right to a determination by an
Independent Third Party pursuant to Section 4.05 hereof with respect to all computations to which it agrees with its share (this statement referred to as the "Interested Party Notice"). For the
avoidance of doubt, in the Interested Party Notice, the Interested Party may set forth its disagreement with the absolute amount of any adjustment set forth in the Controlling Party Notice as well as
the amount of any Distributing Tax Adjustment, Distributing Tax Benefit, Tronox Tax Adjustment or Tronox Tax Benefit contained in the Controlling Party Notice. The failure of an Interested Party to
provide the Interested Party Notice to the Controlling Party within the ninety (90) day period specified in the preceding sentence shall be deemed to conclusively indicate that such Interested
Party agrees with the computations set forth in the Controlling Party and that such Interested Party waives its right to a determination by an Independent Third Party with respect to all such
computations pursuant to Section 4.05 hereof. The Controlling Party or the Interested Party, as the case may be, shall pay as specified in Article III hereof, the amount, if any, of any
Distributing Tax Adjustment, Distributing Tax Benefit, Tronox Tax Adjustment or Tronox Tax Benefit that is not a Disputed Adjustment to the appropriate party. 


c)    During
the ninety (90) day period immediately following the Controlling Party's receipt of the Interested Party Notice, the Controlling Party and the Interested Party shall in
good faith confer with each other to resolve any disagreement over each Disputed Adjustment that was specifically enumerated in such Interested Party Notice. At the end of such ninety (90) day
period, unless otherwise extended in writing by mutual consent of the parties, the Interested Party shall be deemed to agree with all Disputed Adjustments that were specifically enumerated in the
Interested Party Notice and waive its right to a determination by an Independent Third Party pursuant to Section 4.05 hereof with respect to all such Disputed Adjustments unless, and to the
extent that, at any time during such ninety (90) day (or extended) period, either the Controlling Party or the Interested Party has given the other party written notice that it is seeking a
determination by an Independent Third Party pursuant to Section 4.05 hereof regarding the propriety of any such Disputed Adjustment. If the Disputed Adjustments are not referred to an
Independent Third Party, then the Controlling Party or the Interested Party, as the case may be, shall pay as specified in Article III hereof, the amount, if any, of any Distributing Tax
Adjustment, Distributing Tax Benefit, Tronox Tax Adjustment or Tronox Tax Benefit (as adjusted pursuant to any agreement between the parties reached during the ninety (90) day period described
in this Section 4.04(c)) to the appropriate party.

SECTION
4.05    Tax Contest Dispute Resolution.    


a)    In
the event that either a Controlling Party or an Interested Party has given the other party written notice as required under Section 4.04(c) hereof that it is seeking a
determination by an Independent Third Party pursuant to this Section 4.05 with respect to any Disputed Adjustment that was enumerated in an Interested Party Notice, then the parties shall,
within ten (10) days after a party has received such notice, jointly select an Independent Third Party to make such determination. In the event that the parties cannot jointly agree on an
Independent Third Party within such ten (10) day period, then the Controlling Party and the Interested Party shall each immediately select an Independent Third Party and the Independent Third
Parties so selected by the parties shall jointly select, within ten (10) days of their selection, another Independent Third Party. 


b)    In
making its determination as to the propriety of any Disputed Adjustment, the Independent Third Party elected pursuant to Section 4.05(a) hereof shall assume that the
Interested Party is not required or entitled under applicable law to be a member of any consolidated return. In addition, the Independent Third Party shall make its determination according to the
following procedure: 


        (i)    The
Independent Third Party shall analyze each Disputed Adjustment for which a determination is sought pursuant to this Section 4.05 on a stand-alone basis to
determine whether the actual outcome reached with respect to such Disputed Adjustment as reflected in the Final Determination of the Tax Contest was fair and appropriate taking into account the
following exclusive criteria: (A) the facts relating to such adjustment, (B) the applicable law, if any, with respect to such adjustment, (C) the position of the applicable Taxing
Authority with respect to compromise, settlement or litigation of such adjustment, (D) the strength of the factual and legal arguments made by the Controlling Party in reaching the outcome with
respect to such adjustment as reflected in the Final Determination of the Tax Contest and (E) the strength of the factual and legal arguments being made by the Interested Party for the
alternative outcome being asserted by such Interested Party (including the availability of fact, information and documentation to support such alternative outcome). Based on this analysis, the
Independent Third Party shall determine what is the fair and appropriate outcome (hereinafter referred to as the "Ultimate Determination") with respect to each such adjustment. 



        (ii)   The
Interested Party shall only be entitled to modification of its share of a Disputed Adjustment under this Section 4.05 if either (A) the amount that
would be paid by the Interested Party under the Ultimate Determination with respect to such Disputed Amount is less than 80% of the amount that would be paid by the Interested Party with respect to
the Disputed Adjustment as set forth in the Controlling Party Notice or (B) the amount that would be received by the Interested Party under the Ultimate Determination with respect to such
Disputed Adjustment is more than 120% of the amount that the Interested Party would receive with respect to such Disputed Adjustment as set forth in the Controlling Party Notice. If an Interested
Party is entitled to modification of its share of any Disputed Adjustment under the preceding sentence, the amount the Interested Party is entitled to receive, or is required to pay, as the case may
be, with respect to such Disputed Adjustment shall be equal to the amount of the Ultimate Determination of such Disputed Adjustment. 


c)    Any
determination made or notice given by an Independent Third Party pursuant to this Section 4.05 shall be (i) in writing, (ii) made within sixty (60) days
following the selection of the Independent Third Party unless such period is otherwise extended by the mutual consent of the parties and (iii) final and binding upon the parties. The costs of
any Independent Third Party shall be borne equally by the parties. The Controlling Party and the Interested Party shall provide the Independent Third Party with such information or documentation as
may be appropriate or necessary in order for such Independent Third Party to make the determination requested of it. Upon issuance of an Independent Third Party's notice under this
Section 4.05, the Controlling Party or the Interested Party, as the case may be, shall pay as specified in Article III hereof, the amount, if any, of the Distributing Tax Adjustment,
Distributing Tax

the Pre-Deconsolidation Date Period, if a Tax Contest involving the same or similar factual and legal issues that are at issue in the Claims Court Litigation arises, Distributing shall be
the Controlling Party and Tronox shall be an Interested Party. 


SECTION
4.07    Costs and Expenses.    The costs and expenses of a Controlling Party and an Interested Party in controlling or
participating in (as applicable) a Tax Contest shall be borne by the party incurring such costs and expenses.

    MISCELLANEOUS PROVISIONS    



SECTION
7.01    Tax Characterization of Payments.    For all Tax purposes, and notwithstanding any other provision of this
Agreement, to the extent permitted by applicable law, the parties hereto shall treat any payment made pursuant to this Agreement as a capital contribution or dividend distribution, as the case may be,
immediately before the Deconsolidation Date and, accordingly, as not includible in the taxable income of the recipient. If any payment under this Agreement is not permitted to be so treated (because, 


16







 

for
example, the payment relates to an event occurring after the Deconsolidation Date) or as a result of a Final Determination it is determined that the receipt or accrual of any payment made under
this Agreement is taxable to the recipient of such payment, the party making the payment shall pay to the recipient an amount equal to any increase in the income Taxes of the recipient as a result of
receiving the payment (grossed up to take into account such payment, if applicable). 


SECTION
7.02    Payment.    All payments to be made hereunder shall be made in immediately available funds. Except as otherwise
provided, all payments required to be made pursuant to this Agreement shall be due 30 days after the receipt of notice of such payment or, where no notice is required, 30 days after the
fixing of liability or the resolution of a dispute. Payments shall be deemed made when received. Any payment that is not made when due shall bear interest at a rate equal to            for
each
day until paid. 


SECTION
7.03    Joint and Several Liability of Group Members.    Each member of the Distributing Group shall be jointly and
severally liable for the obligations of each other member of the Distributing Group hereunder. Each member of the Tronox Group shall be jointly and severally liable for the obligations of each other
member of the Tronox Group hereunder. 


SECTION
7.04    Performance.    Distributing agrees and acknowledges that Distributing shall be responsible for the performance of
the obligations of each member of the Distributing Group hereunder applicable to such member. Tronox agrees and acknowledges that Tronox shall be responsible for the performance by each member of the
Tronox Group of the obligations hereunder applicable to such member.

        This
Agreement shall be governed by the laws applicable to contracts entered into and to be performed within the State of New York. 


SECTION
7.07    Jurisdiction.    



        Each
party agrees to submit itself exclusively to the personal jurisdiction of any New York court in the event any dispute arises out of this Agreement or any of the transactions
contemplated by this Agreement and agrees that it will not attempt to deny or defeat such personal jurisdiction or venue by motion or other request for leave from any such New York court. Each party

SECTION
7.09    Entire Agreement.    


        This

        Except
as otherwise set forth herein, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns;  provided, however, that no party hereto or thereto may assign its respective rights or delegate its
respective obligations under this Agreement without the express prior written consent of the other party hereto or thereto (such consent not to be unreasonably withheld or delayed). 


SECTION
7.11    Counterparts.

Agreement may be executed in three or more counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same.

7.12    Severability.    



        If
any provision of this Agreement or the application of any such provision to any person or circumstances shall be held invalid, illegal, or unenforceable in any respect by a court of
competent jurisdiction, such invalidity, illegality, or unenforceability shall not affect any other provision hereof. 


SECTION

        Headings
of sections in this Agreement are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement.
