(h) Purchase Price Adjustments .

     (i) Pre-Closing Adjustment for Excluded Tiwest Joint Venture Interests . If a Tiwest Joint Venture Participant or any other Person acquires any or all Tiwest Joint Venture Interests pursuant to the exercise by such Person of its pre-emptive, first refusal or similar rights in accordance with the Tiwest Joint Venture Documents prior to the Closing (such acquired Tiwest Joint Venture Interests, the “ Excluded Tiwest Joint Venture Interests ”), then the Initial Purchase Price payable by Buyers at the Closing shall be reduced by an amount in cash equal to the Tiwest Amount with respect to the Excluded Tiwest Joint Venture Interests.

     (ii) Pre-Closing Adjustment for Acquired Henderson Assets and Acquired Henderson Intellectual Property . If U.S. Sellers fail to obtain those certain consents from the Colorado River Commission with respect to the assignments to U.S. Buyer of the Colorado River Commission Contracts at least ten Business Days prior to the Closing Date, then U.S. Sellers shall provide written notice of such failure to U.S. Buyers. U.S. Buyer shall have the right, by delivering a written notice to U.S. Sellers not later than five Business Days after receipt of the notice referred to in the previous sentence, (A) to not acquire the Acquired Henderson Assets, (B) to not acquire the Acquired Henderson Intellectual Property, and (C) to not enter into the Henderson Lease Agreement, in each case, at the Closing. If U.S. Buyer delivers such election notice to U.S. Sellers within the time period set forth in the preceding sentence, then (1) the Acquired Henderson Assets and the Acquired Henderson Intellectual Property shall constitute Excluded Assets for all purposes of this Agreement, (2) neither U.S. Buyer nor U.S. Sellers shall enter into (or be required to enter into) the Henderson Lease Agreement, and (3) the Initial Purchase Price shall be reduced by the Henderson Amount, as contemplated by Section 2(e)(i) and Section 2(g)(ii)(J) . For the avoidance of doubt, if U.S. Buyer fails to deliver such election notice to U.S. Sellers within the time period set forth above or U.S. Buyer waives its right to make such election, then the Initial Purchase Price otherwise payable shall not be reduced by the Henderson Amount.

     (iii) Pre-Closing Net Working Capital and Rebate Adjustment . For the purpose of determining the Initial Purchase Price, no less than fifteen Business Days prior to the Closing Date, Sellers shall prepare and deliver to U.S. Buyer (A) a statement (such statement, the “ Estimated Net Working Capital Statement ”) setting forth Sellers’ good faith estimate of the Net Working Capital as of 12:01 a.m. (Eastern Standard Time) on the Closing Date (such effective date and time, the “ Adjustment Determination Effective Time ,” and such estimated amount, the “ Estimated Net Working Capital Amount ”), and a

worksheet showing the components and calculation thereof as of the Adjustment Determination Effective Time as well as supporting documentation for such Estimated Net Working Capital Amount, including a reasonably detailed reconciliation of the Assumed Current Liabilities with respect to the Assumed Contracts, and (B) a statement (such statement, the “ Estimated Rebate Statement ”) setting forth Sellers’ good faith estimate of the dollar amount of the Assumed Sales Rebate Liabilities as of the Adjustment Determination Effective Time determined in accordance with GAAP and the Net Working Capital Guidelines (the “ Estimated Rebate Amount ”). In connection with the delivery of the Estimated Net Working Capital Statement, Sellers shall deliver to U.S. Buyer a certificate executed by the Chief Financial Officer, Chief Accounting Officer or Controller of Tronox Incorporated certifying that the Estimated Net Working Capital Statement was prepared and calculated in conformance with the Net Working Capital Guidelines. The Estimated Net Working Capital Statement and the Estimated Rebate Statement shall be subject to the review of U.S. Buyer and, during the period of such review prior to the Closing Date, (1) Sellers shall give U.S. Buyer and its Representatives reasonable access to all Records, facilities and personnel of the Business as reasonably necessary to undertake such review and (2) U.S. Buyer may in good faith dispute any items set forth on the Estimated Net Working Capital Statement (or specific calculations or methods contemplated thereby) or the Estimated Rebate Statement. If U.S. Buyer in good faith disputes the Estimated Net Working Capital Amount or the Estimated Rebate Amount, as applicable, then U.S. Buyer and Sellers shall reasonably cooperate and negotiate in good faith to resolve any dispute regarding the Estimated Net Working Amount or the Estimated Rebate Amount, as applicable, prior to the Closing (the results of any such resolution to be reflected on a new Estimated Net Working Capital Statement or Estimated Rebate Statement, as applicable, which shall be considered the Estimated Net Working Capital Statement or Estimated Rebate Statement, as applicable, for all further purposes); provided that if any item of dispute regarding the Estimated Net Working Capital Statement or Estimated Rebate Statement, as applicable, is not resolved by agreement in writing between U.S. Buyer and Sellers on the date that is at least two Business Days prior to the Closing, then Sellers’ estimate of such disputed item shall be deemed final for purposes of Closing absent manifest error; provided that the Net Working Capital Escrow Amount shall be increased by the amount of any aggregate unresolved difference between Sellers’ estimate and U.S. Buyer’s estimate of the Estimated Net Working Capital Amount and/or the Estimated Rebate Amount. To the extent that the Estimated Net Working Capital Amount exceeds the Target Net Working Capital Amount, the Initial Purchase Price payable at the Closing shall be increased by the amount of the excess, and to the extent that the Estimated Net Working Capital Amount is less than the Target Net Working Capital Amount, the Initial Purchase Price shall be reduced by the amount of such deficiency. To the extent the Estimated Rebate Amount is greater than $0, the Initial Purchase Price shall be reduced by the amount of the Estimated Rebate Amount.

     (iv) Post-Closing Net Working Capital Statement . Within thirty Business Days after the Closing Date, U.S. Buyer shall cause to be prepared and delivered to Sellers (A) a statement (the “ Post-Closing Net Working Capital Statement ”) setting forth the Net Working Capital as of the Adjustment Determination Effective Time, and a worksheet showing the components and calculation thereof as of the Adjustment

Determination Effective Time as well as supporting documentation for such Post-Closing Net Working Capital Statement and (B) a statement (the “ Post-Closing Rebate Statement ”) setting forth the dollar amount of the Assumed Sales Rebate Liabilities as of the Adjustment Determination Effective Time determined in accordance with GAAP (the “ Rebate Amount ”). In connection with the delivery of the Post-Closing Net Working Capital Statement, U.S. Buyer shall deliver to Sellers a certificate executed by the Chief Financial Officer of Guarantor certifying that the Post-Closing Net Working Capital Statement was prepared and calculated in conformance with the Net Working Capital Guidelines.

     (v) Determination of Conclusive Net Working Capital Statement . Sellers will have fifteen Business Days following the receipt of the Post-Closing Net Working Capital Statement and the Post-Closing Rebate Statement to review the Post-Closing Net Working Capital Statement and the Post-Closing Rebate Statement and, during such time, (A) U.S. Buyer shall give Sellers and their Representatives reasonable access to all Records, facilities and personnel of U.S. Buyer (including the Business) as is reasonably necessary to undertake such review and (B) Sellers may dispute any items set forth on the Post-Closing Net Working Capital Statement or the Post-Closing Rebate Statement, as applicable (including the specific calculations and methods contemplated thereby). Unless Sellers deliver written notice(s) to U.S. Buyer of dispute thereof on or prior to the fifteenth Business Day after Sellers’ receipt of the Post-Closing Net Working Capital Statement, Sellers will be deemed to have accepted and agreed to the Post-Closing Net Working Capital Statement and such statement (or specific calculations or methods contemplated thereby) will be final, binding and conclusive. Unless Sellers deliver written notice(s) to U.S. Buyer of a dispute of the Rebate Amount prior to the fifteenth Business Day after Sellers’ receipt of the Post-Closing Rebate Statement, Sellers will be deemed to have accepted and agreed to the Rebate Amount and such Rebate Amount will be final, binding and conclusive. If Sellers notify U.S. Buyer in writing of disputed items contained in the Post-Closing Net Working Capital Statement (or specific calculations or methods contemplated thereby) or that Sellers dispute the Rebate Amount within such fifteen Business Day-period, then for ten Business Days following delivery of such notice by Sellers to U.S. Buyer (the “ Resolution Period ”), U.S. Buyer and Sellers shall attempt in good faith to resolve their differences with respect to the disputed items (the “ Disputed Items ”). Any resolution by U.S. Buyer and Sellers during the Resolution Period as to any Disputed Items shall be set forth in writing and will be final, binding and conclusive. If U.S. Buyer and Sellers do not resolve all Disputed Items by the end of the Resolution Period, then all Disputed Items remaining in dispute shall be submitted within ten calendar days after the expiration of the Resolution Period to an international independent accounting firm mutually acceptable to U.S. Buyer and Sellers (the “ Neutral Arbitrator ”). The Neutral Arbitrator shall act as an arbitrator to determine only those Disputed Items remaining in dispute as of the end of the Resolution Period. In resolving such Disputed Items, the Neutral Arbitrator may not assign a value to any Disputed Item greater than the greatest value for such Disputed Item claimed by any Party or less than the lowest value for such Disputed Item claimed by any Party upon presentment to the Neutral Arbitrator. All fees and expenses relating to the work, if any, to be performed by the Neutral Arbitrator will be allocated between U.S. Buyer and Sellers in the same proportion that the aggregate amount of the Disputed Items so submitted to the Neutral Arbitrator that is

unsuccessfully disputed by each such Party (as finally determined by the Neutral Arbitrator) bears to the total amount of such Disputed Items so submitted. In addition, U.S. Buyer and Sellers shall submit to the Neutral Arbitrator any supporting materials and calculations relating to the Disputed Items. In the event U.S. Buyer or Sellers shall participate in teleconferences or meetings with or make presentations to the Neutral Arbitrator, the other Party shall be entitled to participate in such teleconferences, meetings or presentations except as otherwise required by the Neutral Arbitrator. U.S. Buyer and Sellers shall use their reasonable best efforts to cause the Neutral Arbitrator to deliver to U.S. Buyer and Sellers a written determination (such determination to include a work sheet setting forth all material calculations and methods used in arriving at such determination) of the Disputed Items submitted to the Neutral Arbitrator within ten calendar days of receipt of such Disputed Items, which determination will be final, binding and conclusive and upon which judgment may be entered. The final, binding and conclusive Post-Closing Net Working Capital Statement based either upon agreement or deemed agreement by U.S. Buyer and Sellers or the written determination delivered by the Neutral Arbitrator in accordance with this Section 2(h)(v) will be the “ Conclusive Net Working Capital Statement .” The final, binding and conclusive Rebate Amount based either upon agreement or deemed agreement by U.S. Buyer and Sellers or the written determination delivered by the Neutral Arbitrator in accordance with this Section 2(h)(v) will be the “ Conclusive Rebate Amount .”

     (vi) Post-Closing Adjustment . If (a) the Net Working Capital on the Conclusive Net Working Capital Statement plus the Estimated Rebate Amount exceeds (b) the Estimated Net Working Capital Amount plus the Conclusive Rebate Amount, then U.S. Buyer shall pay Sellers the amount of such excess by wire transfer of immediately available funds to Sellers’ Accounts. If (a) the Estimated Net Working Capital Amount plus the Conclusive Rebate Amount exceeds (b) the Net Working Capital on the Conclusive Net Working Capital Statement plus the Estimated Rebate Amount, then Sellers shall, and Sellers and U.S. Buyer shall provide written instructions to the Escrow Agent to, remit to U.S. Buyer the amount of such excess out of the Net Working Capital Escrow Amount and, in the event such excess, if any, exceeds the Net Working Capital Escrow Amount held in the Escrow Account, then Sellers shall pay U.S. Buyer the amount of such excess by wire transfer of immediately available funds to a bank account designated by U.S. Buyer in writing at least three Business Days prior to the date of such payment. All payments to be made pursuant to this Section 2(h)(vi) shall be made no later than the second Business Day following the date on which U.S. Buyer and Sellers agree, or are deemed to have agreed to, or the Neutral Arbitrator delivers, the Conclusive Net Working Capital Statement and the Conclusive Rebate Amount. Following the determination of the Conclusive Net Working Capital Statement and the Conclusive Rebate Amount and the payment of any amount required pursuant to this Section 2(h)(vi) , the Parties shall cause the Escrow Agent to remit to Sellers the remaining balance, if any, of the Net Working Capital Escrow Amount remaining under the Net Working Capital Escrow Agreement ( i.e. , the remaining Net Working Capital Escrow Amount, if any, together with all accrued investment income or interest on the Net Working Capital Escrow Amount), all in accordance with the provisions of the Net Working Capital Escrow Agreement.

Sellers shall have thirty calendar days to review and consent to such allocation which consent will not be unreasonably withheld, conditioned or delayed. Buyers and Sellers shall report, act and file Tax Returns (including Internal Revenue Service Form 8594 and any other applicable non-United States Tax Returns required to be filed in connection with any asset or equity sale) in all respects and for all purposes consistent with any agreed upon allocation. None of Buyers or Sellers shall take any position (whether in audits, Tax Returns or otherwise) which is inconsistent with such allocation unless required to do so by applicable law.

     (j)  Non-Assignment of Assumed Contracts . Notwithstanding anything contained herein to the contrary, (i) this Agreement shall not constitute an agreement to assign any Contract if, after giving effect to the provisions of sections 363 and 365 of the Bankruptcy Code, an attempted assignment thereof, without obtaining a required consent, waiver, confirmation, novation or approval of any third party, would constitute a breach thereof or in any way negatively affect the rights of Sellers or either Buyer, as the assignee of such Contract, and (ii) no breach of this Agreement shall have occurred by virtue of such non-assignment unless the failure to assign any Contracts would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on the Acquired Business. If, after giving effect to the provisions of sections 363 and 365 of the Bankruptcy Code, such consent, waiver, confirmation, novation or approval is required but not obtained prior to the Closing, Sellers shall use their reasonable best efforts to obtain as expeditiously as possible the written consent, waiver, confirmation, novation or approval, as applicable, of the other party or parties to such Contract necessary for the assignment thereof to either Buyer post-Closing. Unless and until any such consent, waiver, confirmation, novation or approval is obtained, Seller shall reasonably cooperate with Buyers in any reasonable arrangement satisfactory to Buyers designed to provide to Buyers the claims, rights, benefits and obligations of or under any such Contract, including by means of any subcontracting, sublicensing or subleasing arrangement and enforcement for the benefit of Buyers, with Buyers assuming and agreeing to pay Sellers’ obligations, of any and all rights of Sellers against a third party thereto. In such event, (i) Sellers will hold in trust for and promptly pay to the applicable Buyer, when received, all moneys received by them under any such Contract or any claim, right or benefit arising thereunder and (ii) Buyers will promptly pay, perform or discharge, when due, any and all obligations and Liabilities arising thereunder. Notwithstanding any other provision in this Section 2(j) , nothing in this Section 2(j) shall (A) require any Seller to make any more than immaterial expenditure or incur any more than immaterial obligation on its own or on either Buyer’s behalf unless one of Buyers agrees to fully reimburse such Seller promptly or (B) prohibit any Seller from ceasing operations or winding up its affairs following the Closing. Contracts covered by this Section 2(j) shall not be deemed to constitute Excluded Assets solely by virtue of this Section 2(j) .
