EXHIBIT 10.1

FORM OF REGISTRATION RIGHTS AGREEMENT, dated as of , 2005 (this "Agreement"), between Xxxx-XxXxx Corporation, a Delaware corporation ("Xxxx-XxXxx") and Tronox Incorporated, a Delaware corporation (the "Tronox").

INTRODUCTION

Xxxx-XxXxx and Tronox are parties to a Master Separation and Distribution Agreement, dated as of the date hereof (the "Master Separation Agreement"). Capitalized terms used herein and not otherwise defined have the meanings assigned to them in the Master Separation Agreement.

Pursuant to the terms of the Master Separation Agreement, immediately following the consummation of the Initial Public Offering, Xxxx-XxXxx will own directly or indirectly all of the issued and outstanding shares of the Class B common stock, par value $0.01 per share, of Tronox (the "Class B Common Stock"). Pursuant to the Master Separation Agreement, Xxxx-XxXxx has sole and absolute discretion to determine whether to consummate the Distribution.

Tronox and Xxxx-XxXxx desire to make certain arrangements to provide Xxxx-XxXxx with registration rights with respect to shares of Class B Common Stock it owns.

In consideration of the mutual agreements, provisions and covenants set forth in this Agreement the parties, intending to be legally bound, hereby agree as follows:

ARTICLE I
EFFECTIVENESS OF AGREEMENT

Section 1.1. Effective date. This agreement shall become effective upon the Closing Date.

Section 1.2. Shares Covered. This Agreement covers all shares of Class B Common Stock that are beneficially owned by Xxxx-XxXxx or any Permitted Transferee (as defined in Section 2.5) from time to time, whether or not held immediately following the Initial Public Offering (subject to the provisions of Section 7, the "Shares"). The Shares shall include any securities issued or issuable with respect to the Shares by way of a stock dividend or a stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization. Xxxx-XxXxx and any Permitted Transferees are each referred to herein as a "Holder" and collectively as "Holders" and the holders of shares proposed to be included in any registration under this Agreement are each referred to herein as "Selling Holder" and collectively as "Selling Holders".

ARTICLE II
DEMAND REGISTRATION

Section 2.1. Notice. Upon the terms and subject to the conditions set forth herein, upon written notice of any Holder requesting that Tronox effect the registration under the Securities Act, of 1933, as amended (the "Securities Act") of any or all of the Shares held by it, which notice shall specify the intended method or methods of disposition of such Shares (which methods may include, without limitation, a Shelf Registration, a Convertible Registration or an Exchange Registration (as such terms are defined in Section 2.6)), Tronox will, within five days of receipt of such notice from any Holder, give written notice of the proposed registration to all other Holders, if any, and will use its commercially reasonable efforts to effect (at the earliest reasonable date) the registration under the Securities Act of such Shares (and the Shares of any other Holders joining in such request as are specified in a written notice received by Tronox within 15 days after receipt of Tronox's written notice of the proposed registration) for disposition in accordance with the intended method or methods of disposition stated in such request (each registration request pursuant to this Section 2.1 is referred to as herein as a "Demand Registration"); provided, however, that:

(i) Tronox shall not be obligated to effect registration with respect to Shares pursuant to this Section 2 within 90 days after the effective date of a previous registration, other than a Shelf Registration, effected with respect to Class B Common Stock pursuant to this Section 2;

(ii) if at the time a Demand Registration is requested pursuant to this Section 2, Tronox determines in the good faith judgment of the general counsel of Tronox, to be confirmed within 15 days by the Tronox's board of directors (the "Board"), that such registration would reasonably be expected to require the disclosure of material information that Tronox has a bona fide business purpose to keep confidential and the disclosure of which would have a material adverse effect on any active proposal by Tronox or any of its subsidiaries to engage in any material acquisition, merger, consolidation, tender offer, other business combination, reorganization, securities offering or other material transaction, Tronox may postpone the filing or effectiveness of such registration until the earlier of (i) 15 Business Days after the date of disclosure of such material information, or (ii) 75 days after Tronox makes such determination; provided, however, that Tronox may delay a Demand Registration hereunder only once in any 12-month period;

(iii) except in the case of a Convertible Registration or an Exchange Registration, the number of Shares originally requested to be registered pursuant to any registration requested pursuant to this Section 2 shall cover Shares representing at least 10% of the aggregate shares of all classes of Tronox Common Stock then issued and outstanding;

(iv) if a Demand Registration is an underwritten offering and the managing underwriters advise Tronox in writing that in their opinion the number of Shares requested to be included in such offering exceeds the number of Shares that can be sold in an orderly manner in such offering within a price range acceptable to the Holders of a majority of the Shares initially requesting such registration or without materially adversely affecting the market for the Common Stock, Tronox shall include in such registration the number of Shares requested by Holders of a majority of the Shares to be included therein which, in the opinion of such Holders based upon advice of the managing underwriters, can be sold in an orderly manner within the price range of such offering and without materially adversely affecting the market for the Common Stock, pro rata among the respective Holders thereof on the basis of the amount of Common Stock owned by each Holder requesting inclusion of Shares in such registration; and

(v) Tronox shall not be required to effect more than five Demand Registrations pursuant to this Section 2.1; provided, however, that the foregoing limitation shall not be effective if, at the time of the fifth Demand Registration, Tronox is prohibited under then-existing Commission rules from registering all remaining Shares pursuant to a Shelf Registration, regardless of whether the Holder or Holders has requested that such fifth Demand Registration be a Shelf Registration or otherwise.

Section 2.2. Registration Expenses. All Registration Expenses (as defined in Section 8.1) for any registration requested pursuant to this Section 2 (including any registration that is delayed or withdrawn) shall be paid by Tronox.

Section 2.3. Selection of Professionals. The Holders of a majority of the Shares included in any Demand Registration shall have the right to select the investment bankers and managers to underwrite or otherwise administer the offering. The Holders of a majority of the Shares included in any Demand Registration shall have the right to select the financial printer, the solicitation or exchange agent (if any) and counsel for the Selling Holders. Tronox shall have the right to select its own outside counsel and, subject to the provisions of the Master Separation Agreement, independent auditors.

Section 2.4. Third Person Shares. (a) Tronox shall have the right to cause the registration of securities for sale for the account of any Person (as defined in Section 6.1) (including Tronox) other than the Selling Holders (the "Third Person Shares") in any registration of Shares requested pursuant to this Section 2 so long as the Third Person Shares are disposed of in accordance with the intended method or methods of disposition requested pursuant to this Section 2; provided, however, that Tronox shall not have the right to cause the registration of such securities of such other Persons if the registration requested pursuant to this Section 2 is a Convertible Registration or an Exchange Registration.

(b) If a Demand Registration in which Tronox proposes to include Third Person Shares is an underwritten offering and the managing underwriters advise Tronox in writing that in their opinion the number of Shares and Third Person Shares requested to be included in such offering exceeds the number of Shares and Third Person Shares that can be sold in an orderly manner in such offering within a price range acceptable to the Holders of a majority of the Shares initially requesting such registration or without materially adversely affecting the market for the Tronox Common Stock (the "Maximum Number"), Tronox shall not include in such registration any Third Person Shares unless all of the Shares initially requested to be included therein are so included, and then only to the extent of the Maximum Number.

Section 2.5. Permitted Transferees. As used herein, "Permitted Transferee" shall mean any transferee, whether direct or indirect, of Shares identified by Xxxx-XxXxx (or a subsequent Holder) in a written notice to Tronox. Any Permitted Transferees of the Shares shall be subject to and bound by all of the terms and conditions herein applicable to Holders. The notice required by this Section 2.5 shall be signed by both the transferring Holder and the Permitted Transferees so designated and shall include an undertaking by the Permitted Transferees to comply with the terms and conditions of this Agreement applicable to Holders.

Section 2.6. Shelf Registration; Convertible Registration; Exchange Registration; Distribution. With respect to any Demand Registration, the requesting Holders may request Tronox to effect a registration of the Shares (a) under a registration statement pursuant to Rule 415 under the Securities Act (or any successor rule) (a "Shelf Registration"); (b) in connection with such Holders' registration under the Securities Act of securities (the "Convertible Securities") convertible into, exercisable for or otherwise related to the Shares (a "Convertible Registration"); (c) in connection with such Holders' distribution of, or exchange of or offer to exchange the Shares for, any debt or equity securities of such Holders, a subsidiary or affiliate thereof or any other Person (an "Exchange Registration"); or (d) in the form of a Distribution as defined in the Master Separation Agreement.

Section 2.7. Commission Form. Tronox shall use its commercially reasonable efforts to cause a Demand Registration to be registered on Form S-3 (or any successor form), and if Tronox is not then eligible under the Securities Act to use Form S-3, a Demand Registration shall be registered on Form S-1 (or any successor form). If a Demand Registration is a Convertible Registration or an Exchange Registration, Tronox shall effect such registration on the appropriate Form under the Securities Act for such registrations. Tronox shall use its commercially reasonable efforts to become eligible to use Form S-3 and, after becoming eligible to use Form S-3, shall use its commercially reasonable efforts to remain so eligible. All such registration statements shall comply with applicable requirements of the Securities Act and the Commission's rules and regulations thereunder, and, together with each prospectus included, filed or otherwise furnished by Tronox in connection therewith, shall not contain any untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Tronox shall timely file all reports on Forms 10-K, 10-Q and 8-K (or any successor forms), and all material required to be filed, pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), to the extent that such filing shall be a condition to initial filing or continued use or effectiveness of any Demand Registration.

Section 2.8. Other Registration Rights. Tronox shall not grant to any Persons the right to request Tronox to register any equity securities of Tronox, or any securities convertible or exchangeable into or exercisable for such securities, whether pursuant to "demand," "piggyback," or other rights, unless such rights are subject and subordinate to the rights of the Holders under this Agreement.

Section 2.9. Withdrawal. The Holders may withdraw a Demand Registration at any time and under any circumstances.

ARTICLE III
PIGGYBACK REGISTRATIONS

Section 3.1. Notice and Registration. (a) If Tronox proposes to register any of its securities for public sale under the Securities Act (whether proposed to be offered for sale by Tronox or any other Person), on a form and in a manner that would permit registration of the Shares for sale to the public under the Securities Act (a "Piggyback Registration"), it will give prompt written notice to the Holders of its intention to do so, and upon the written request of any or all of the Holders delivered to Tronox within 20 days after the giving of any such notice (which request shall specify the Shares intended to be disposed of by such Holders), Tronox will use its commercially reasonable efforts to effect, in connection with the registration of such other securities, the registration under the Securities Act of all of the Shares that Tronox has been so requested to register by such Holders (which shall then become Selling Holders), to the extent required to permit the disposition (in accordance with the same method of disposition as Tronox proposes to use to dispose of the other securities) of the Shares to be so registered; provided, however, that:

(i) if, at any time after giving such written notice of its intention to register any of its other securities and prior to the effective date of the registration statement filed in connection with such registration, Tronox shall determine for any reason not to register such other securities, Tronox may, at its election, give written notice of such determination to the Selling Holders (or, if prior to delivery of the Holders' written request described above in this Section 3.1, the Holders) and thereupon Tronox shall be relieved of its obligation to register such Shares in connection with the registration of such other securities (but not from its obligation to pay Registration Expenses to the extent incurred in connection therewith as provided in Section 3.3), without prejudice, however, to the rights (if any) of any Selling Holders immediately to request (subject to the terms and conditions of Section 2) that such registration be effected as a registration under Section 2 or to include such Shares in any subsequent Piggyback Registration pursuant to this Section 3;

(ii) Tronox shall not be required to effect any registration of the Shares under this Section 3 incidental to the registration of any of its securities in connection with mergers, acquisitions, exchange offers, subscription offers, dividend reinvestment plans or stock option or other employee benefit plans of Tronox; and

(iii) if a Piggyback Registration is an underwritten registration on behalf of Tronox (whether or not selling security holders are included therein) and the managing underwriters advise Tronox in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without materially adversely affecting the marketability of the offering or the market for the Common Stock (the "Piggyback Maximum Number"), Tronox shall include the following securities in such registration up to the Piggyback Maximum Number and in accordance with the following priorities: (i) first, the securities Tronox proposes to sell, (ii) second, up to the number of Shares requested to be included in such registration, pro rata among the Selling Holders of such Shares on the basis of the number of Shares owned by each such Selling Holder, and (iii) third, up to the number of any other securities requested to be included in such registration.

(b) No registration of Shares effected under this Section 3 shall relieve Tronox of its obligation to effect a registration of Shares pursuant to Section 2.

(c) Any Selling Holder may withdraw any or all of its Shares from a Piggyback Registration at any time under any circumstances.

Section 3.2. Selection of Professionals. If any Piggyback Registration is an underwritten offering and any of the investment bankers or managers selected to administer the offering was not one of the joint book-running managers of the Initial Public Offering, such investment banker or manager shall not administer such offering if the Holders of a majority of the Shares included in such Piggyback Registration

reasonably object thereto. The Holders of a majority of the Shares included in any Piggyback Registration shall have the right to select counsel for the Selling Holders. Tronox shall select its own outside counsel and, subject to the terms of the Master Separation Agreement, its independent auditors.

Section 3.3. Registration Expenses. Tronox will pay all of the Registration Expenses in connection with any registration pursuant to this Section 3.

ARTICLE IV
REGISTRATION PROCEDURES

Section 4.1. Registration and Qualification. (a) If and whenever Tronox is required to use its commercially reasonable efforts to effect the registration of any Shares under the Securities Act as provided in Sections 2 and 3, including an underwritten offering pursuant to a Shelf Registration, Tronox will as promptly as is practicable (but in no event, in the case of the initial filing of the registration statement, later than 30 days after the date of a demand under Section 2 if the applicable registration form is Form S-3 or a successor form, and for any other form, 90 days from the date of such demand):

(i) prepare and file with the Commission a registration statement with respect to such Shares and use its commercially reasonable efforts to cause such registration statement to become effective as soon as practicable after the initial filing thereof; provided that before filing a registration statement or prospectus or any amendments or supplement thereto, Tronox shall furnish to the counsel selected by the Holders of a majority of the Shares covered by such registration statement copies of all such documents proposed to be filed (which documents shall be subject to the review and comment of such counsel);

(ii) except in the case of a Shelf Registration, Convertible Registration or Exchange Registration, prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all of the Shares until the earlier of (i) such time as all of such Shares have been disposed of in accordance with the intended methods of disposition set forth in such registration statement or (ii) the expiration of nine months after such registration statement becomes effective, plus the number of days that any filing or effectiveness has been delayed under Section 2.1(ii);

(iii) in the case of a Shelf Registration (but not including any Convertible Registration), prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all Shares subject thereto for a period ending on the earlier of (x) 24 months after the effective date of such registration statement plus the number of days that any filing or effectiveness has been delayed under Section 2.1(ii) or suspended under Section 4.3(a) and (y) the date on which all the Shares subject thereto have been sold pursuant to such registration statement (the "Shelf Effective Period");

(iv) in the case of a Convertible Registration or an Exchange Registration, prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all of the Shares subject thereto until such time as the rules, regulations and requirements of the Securities Act and the terms of the Convertible Securities no longer require such Shares to be registered under the Securities Act (the "Convertible Effective Period");

(v) furnish to the Selling Holders and to any underwriter of such Shares such number of conformed copies of such registration statement and of each such amendment and supplement thereto (in each case including all exhibits), such number of copies of the prospectus included in such

registration statement (including each preliminary prospectus and any summary prospectus), in conformity with the requirements of the Securities Act, such documents incorporated by reference in such registration statement or prospectus, and such other documents as the Selling Holders or such underwriter may reasonably request;

(vi) use its commercially reasonable efforts to register or qualify all of the Shares covered by such registration statement under such other securities or blue sky laws of such jurisdictions as the Selling Holders or any underwriter of such Shares shall reasonably request, and do any and all other acts and things that may be necessary or advisable to enable the Selling Holders or any underwriter to consummate the disposition in such jurisdictions of the Shares covered by such registration statement, except that Tronox shall not for any such purpose be required to qualify generally to do business as a foreign corporation in any jurisdiction where it is not so qualified, or to subject itself to taxation in any such jurisdiction, or to consent to general service of process in any such jurisdiction;

(vii) (x) furnish to the Selling Holders, addressed to them, an opinion of counsel for Tronox and (y) use its commercially reasonable efforts to furnish to the Selling Holders, addressed to them, a "cold comfort" letter signed by the independent public accountants who have certified Tronox's financial statements included in such registration statement, covering substantially the same matters with respect to such registration statement (and the prospectus included therein) and, in the case of such accountants' letter, with respect to events subsequent to the date of such financial statements, as are customarily covered in opinions of issuer's counsel and in accountants' letters delivered to underwriters in underwritten public offerings of securities and such other matters as the Selling Holders may reasonably request, in each case, in form and substance and as of the dates reasonably satisfactory to the Selling Holders;

(viii) immediately notify the Selling Holders, at any time when a prospectus relating to a registration pursuant to Articles II or III is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and at the request of the Selling Holders prepare and furnish to the Selling Holders a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Shares, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading;

(ix) permit any Selling Holders comprising holders of a majority of the Shares to be included in such registration statement, in their sole and exclusive judgment, to participate in the preparation of such registration or comparable statement (including but not limited to having prompt access to any Commission comment letters or other communications in connection with such registration and Tronox's responses thereto) and to require the insertion therein of material, furnished to Tronox in writing, which in the reasonable judgment of such Selling Holders and their counsel should be included;

(x) to make available members of management of Tronox, as selected by the Holders of a majority of the Shares included in such registration statement, for assistance in the selling effort relating to the Shares covered by such registration, including, but not limited to, the participation of such members of Tronox's management in road show presentations;

(xi) in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any securities included in such registration statement for sale in any jurisdiction,

Tronox shall use it commercially reasonable efforts promptly to obtain the withdrawal of such order; and

(xii) use its commercially reasonable efforts to cause Shares covered by such registration statement to be registered with or approved by such other government agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Shares.

(b) Tronox may require the Selling Holders to furnish the Tronox with such information regarding the Selling Holders and the distribution of the Shares as Tronox may from time to time reasonably request in writing and as shall be required by law, the Commission or any securities exchange on which any shares of Common Stock are then listed for trading in connection with any registration.

Section 4.2. Underwriting. If requested by the underwriters for any underwritten offering in connection with a registration requested hereunder (including any registration under Section 3 which involves, in whole or in part, an underwritten offering), Tronox will enter into an underwriting agreement with such underwriters for such offering, such agreement to contain such representations and warranties by Tronox and such other terms and provisions as are customarily contained in underwriting agreements with respect to that offering, including, without limitation, indemnities and contribution to the effect and to the extent provided in Article VI and the provision of opinions of counsel and accountants' letters to the effect and to the extent provided in Section 4.1(a)(vii). Tronox may require that the Shares requested to be registered pursuant to Article III be included in such underwriting on the same terms and conditions as shall be applicable to the other securities being sold through underwriters under such registration; provided, however, that no Selling Holder shall be required to make any representations or warranties to Tronox or the underwriters (other than representations and warranties regarding such Holder and such Holder's intended method of distribution) or to undertake any indemnification obligations to Tronox or the underwriters with respect thereto, except as otherwise provided in Section 6.2 hereof. The Selling Holders shall be parties to any such underwriting agreement, and the representations and warranties by, and the other agreements on the part of, Tronox to and for the benefit of such underwriters shall also be made to and for the benefit of such Selling Holders.

Section 4.3. Blackout Periods for Shelf Registrations. (a) At any time when a Shelf Registration effected pursuant to Article II relating to the Shares is effective, upon written notice from Tronox to the Selling Holders that Tronox determines in the good faith judgment of the general counsel of Tronox, to be confirmed within 15 days by the Board, that (i) the Selling Holders' sale of the Shares pursuant to the Shelf Registration would require disclosure of material information that Tronox has a bona fide business purpose for preserving as confidential and the disclosure of which would have a material adverse effect on Tronox or (ii) Tronox is unable to comply with Commission requirements for continued use or effectiveness of the Shelf Registration (in the case of either clause (i) or (ii), for convenience, referred to as an "Information Blackout"), the Selling Holders shall suspend sales of Shares pursuant to such Shelf Registration until the earlier of (A) the date upon which such material information is disclosed to the public or ceases to be material (or Tronox otherwise complies with applicable Commission requirements), (B) 90 days after the general counsel of Tronox makes such good faith determination (as subsequently confirmed by the Board) unless resuming use of the Shelf Registration is then prohibited by applicable Commission rules or published interpretations, or (C) such time as Tronox notifies the Selling Holders that sales pursuant to such Shelf Registration may be resumed (the number of days from such suspension of sales of the Selling Holders until the day when such sales may be resumed hereunder is hereinafter called a "Sales Blackout Period").

(b) If there is an Information Blackout and the Selling Holders do not notify Tronox in writing of their desire to cancel such Shelf Registration, the period set forth in Section 4.1(a)(iii)(x) shall be extended for a number of days equal to the number of days in the Sales Blackout Period. The fact that a Sales Blackout Period is required under this Section 4.3 or Commission rules shall not relieve the contractual

duty of Tronox as set forth in Section 2.7 to file timely reports and otherwise file material required to be filed under the Exchange Act.

Section 4.4. Listing and Other Requirements. In connection with the registration of any offering of Shares pursuant to this Agreement, Tronox agrees to use commercially reasonable efforts to effect the listing of such Shares on any securities exchange on which any shares of any class of Tronox Common Stock are then listed and otherwise facilitate the public trading of such Shares. Tronox will take all other lawful actions reasonably necessary and customary under the circumstances to expedite and facilitate the disposition by the Selling Holders of Shares registered pursuant to this Agreement as described in the prospectus relating thereto, including without limitation timely preparation and delivery of stock certificates in appropriate denominations and furnishing any required instructions or legal opinions to Tronox's transfer agent in connection with Shares sold or otherwise distributed pursuant to an effective registration statement.

Section 4.5. Holdback Agreements. (a) Tronox shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the seven days prior to and during the 90-day period beginning on the effective date of any registration statement in connection with a Demand Registration (other than a Shelf Registration) or a Piggyback Registration, except pursuant to registrations on Form S-8 or any successor form or unless the underwriters managing any such public offering otherwise agree in writing.

(b) If the Holders notify Tronox in writing that they intend to effect an underwritten sale of Shares registered pursuant to a Shelf Registration pursuant to Article II hereof, Tronox shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for its equity securities, during the seven days prior to and during the 90-day period beginning on the date of the proposed sale, except pursuant to registrations on Form S-8 or any successor form or unless the underwriters managing any such public offering otherwise agree in writing.

(c) If Tronox completes an underwritten registration with respect to any of its securities (whether offered for sale by Tronox or any other Person) on a form and in a manner that would have permitted registration of the Shares, if no Holder requested the inclusion of any Shares in such registration, and if Tronox gives each Holder at least 20 days prior written notice of the approximate date on which such offering is expected to be commenced, the Holders shall not effect any public sales or distributions of equity securities of Tronox, or any securities convertible into or exchangeable or exercisable for such securities, until the termination of the holdback period required from Tronox by any underwriters in connection with such previous registration; provided that the holdback period applicable to the Holders shall (i) in no event be longer than a period of seven days before and 90 days after the effective date of such registration or apply to the Holders more than once in any 12-month period, (ii) not apply to any Distribution under the Master Separation Agreement, (iii) not apply to any securities of Tronox acquired on the open market, (iv) not apply to any Holder owning less than 10% of Tronox's outstanding voting securities and (v) not apply unless all directors and officers of Tronox and holders of 10% or more of the Tronox's outstanding voting securities are bound by the same holdback restrictions as are intended to apply to the Holders.

ARTICLE V
PREPARATION; REASONABLE INVESTIGATION

Section 5.1. Preparation; Reasonable Investigation. In connection with the preparation and filing of each registration statement registering the Shares under the Securities Act and each sale of the Shares thereunder, Tronox will give the Selling Holders and the underwriters, if any, and their respective counsel and accountants, access to its financial and other records, pertinent corporate documents and properties of Tronox and such opportunities to discuss the business of Tronox with its officers and the independent public accountants who have certified its financial statements as shall be necessary, in the opinion of the

Selling Holders and such underwriters or their respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act.

ARTICLE VI
INDEMNIFICATION AND CONTRIBUTION

Section 6.1. Indemnification of Selling Holders. In the event of any registration of any of the Shares hereunder, Tronox will enter into customary indemnification arrangements to indemnify and hold harmless each of the Selling Holders, each of their respective directors and officers, each Person (as defined below) who participates as an underwriter in the offering or sale of such securities, each officer and director of each underwriter, and each Person, if any, who controls each such Selling Holder or any such underwriter within the meaning of the Securities Act (collectively, the "Covered Persons") against any losses, claims, damages, liabilities and expenses, joint or several, to which such Person may be subject under the Securities Act or otherwise insofar as such losses, claims, damages, liabilities or expenses (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any related registration statement filed under the Securities Act, any preliminary prospectus or final prospectus included therein, or any amendment or supplement thereto, or any document incorporated by reference therein, or (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and Tronox will reimburse each such Covered Person, as incurred, for any legal or any other expenses reasonably incurred by such Covered Person in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided, however, that Tronox shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus or final prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to Tronox by such Selling Holder or such underwriter specifically for use in the preparation thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any such Covered Person and shall survive the transfer of such securities by the Selling Holders. In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (a) any Holder exercising rights under this Agreement, or any controlling person of any such Holder, makes a claim for indemnification pursuant to this Section 6.1, but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 6.1 provides for indemnification in such case, or (b) contribution under the Securities Act may be required on the part of any such Selling Holder or any such controlling person in circumstances for which indemnification is provided under this Section 6.1, then, and in each such case, Tronox and such Holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion so that such Holder is responsible for the portion represented by the percentage that the public offering price of its Shares offered by and sold under the registration statement bears to the public offering price of all securities offered by and sold under such registration statement, and Tronox and other Selling Holders are responsible for the remaining portion; provided, however, that, in any such case: (i) no such Holder will be required to contribute any amount in excess of the net amount of proceeds of all such Shares offered and sold by such Holder pursuant to such registration statement; and (ii) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation. "Person" means an individual, a partnership, a corporation, a limited liability company, an association, a joint stock company, a trust, a joint venture, an unincorporated organization and a governmental entity, or any department, agency or political subdivision thereof.

Section 6.2. Indemnification by the Selling Holders. Each of the Selling Holders, by virtue of exercising its respective registration rights hereunder, agrees and undertakes to enter into customary indemnification arrangements to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 6.1) Tronox, its directors and officers, each Person who participates as an underwriter in the offering or sale of such securities, each officer and director of each underwriter, and each Person, if any, who controls Tronox or any such underwriter within the meaning of the Securities Act, with respect to any statement in or omission from such registration statement, any preliminary prospectus or final prospectus included therein, or any amendment or supplement thereto, if such statement or omission is contained in written information furnished by such Selling Holder to Tronox specifically for inclusion in such registration statement or prospectus; provided, however, that the obligation to indemnify shall be individual, not joint and several, for each Selling Holder and shall be limited to the net amount of proceeds received by such Selling Holder from the sale of Shares pursuant to such registration statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of Tronox or any such director, officer or Person and shall survive the transfer of the registered securities by the Selling Holders.

Section 6.3. Indemnification Procedures. Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided, however, that the failure to give prompt notice shall not impair any Person's rights to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (ii) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without the indemnifying party's consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to (as a result of a conflict of interest, as determined in the indemnified party's reasonable judgment), or who elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim.
