 Exhibit A 

Term Loan Amendment 
 (See Attached.) 

 EXECUTION COPY 
 SECOND AMENDMENT 
 TO CREDIT AND GUARANTY AGREEMENT 

THIS SECOND AMENDMENT TO CREDIT AND GUARANTY AGREEMENT (this “Amendment”) is dated as of March 19,
2013 and is entered into by and among TRONOX PIGMENTS (NETHERLANDS) B.V., a private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) incorporated under Dutch law, having its corporate seat
(statutaire zetel) in Amsterdam, The Netherlands and having its registered office address at Naritaweg 165, Telestone 8, (1043BW), Amsterdam, The Netherlands, registered with the trade register of the chamber of commerce in Amsterdam, The
Netherlands under number 34132341 (the “Borrower”), TRONOX LIMITED (ACN 153 348 111), an Australian public limited company incorporated in the Commonwealth of Australia (“Holdings”), the Lenders
party hereto, GOLDMAN SACHS BANK USA (“GS”), as Administrative Agent (“Administrative Agent”), and the GUARANTORS listed on the signature pages hereto, and is made with reference to that certain
CREDIT AND GUARANTY AGREEMENT dated as of February 8, 2012 (as amended by that certain First Amendment to Credit and Guaranty Agreement dated as of May 11, 2012 and as further amended through the date hereof without giving effect to
the amendments set forth herein, the “Existing Credit Agreement”) by and among the Borrower, Holdings, Tronox Incorporated, a Delaware corporation (“US Holdings”), the subsidiaries of Holdings named
therein or from time to time party thereto, the Lenders, the Administrative Agent, Collateral Agent and the other Agents named therein. Capitalized terms used herein without definition shall have the same meanings herein as set forth in the Existing
Credit Agreement after giving effect to this Amendment. 
 RECITALS 

WHEREAS, the Credit Parties have requested that the Lenders agree to amend certain provisions of the Existing Credit Agreement as
provided for herein to, among other things, obtain additional Term Loans (the “Additional Term Loans”) in an aggregate principal amount of up to $952,749,999.73 (the “Additional Term Loan Amount”),
such that after giving effect to such Additional Term Loans, the aggregate principal amount of all Term Loans would equal $1,500,000,000; 
 WHEREAS, it is the intention of the Credit Parties and the Lenders that all Additional Term Loans be Term Loans and that the existing Term Loans and the Additional Term Loans have identical terms
and be treated as one class of loans under the Existing Credit Agreement, as amended by this Amendment; 
 WHEREAS, the
Additional Term Loans may be provided by Lenders under the Existing Credit Agreement and/or by Persons that are not currently Lenders under the Existing Credit Agreement; and 
 WHEREAS, subject to the conditions set forth herein, the Lenders party hereto are willing to agree to such amendments relating to the Existing Credit Agreement and, in certain cases, commit to
provide a portion of the Additional Term Loans (such commitment an “Additional Term Loan Commitment”). 

NOW, THEREFORE, in consideration of the premises and the agreements, provisions and covenants herein contained, the parties hereto
agree as follows: 

 SECTION I. AMENDMENT 
 1.1 The Existing Credit Agreement (including the appendices, schedules and exhibits thereto) is hereby amended and restated in its entirety to be in the form of Exhibit A attached hereto (as
amended and restated pursuant to this Amendment, the “Restated Credit Agreement”). 
 SECTION II. LENDER CONSENTS

  

	2.1	Each Lender that, on or prior to 10:00 a.m. (New York time) on March 13, 2013 (as such time and date may be extended by the Administrative Agent with the consent
of the Borrower, the “Consent Due Date”) has executed and delivered to the Administrative Agent a Consent to Second Amendment substantially in the form attached hereto as Annex A (the “Consent”)
shall have consented to this Amendment. 

  

	2.2	Each Person (such Person, an “Additional Lender”) that is not a Lender under the Existing Credit Agreement that executes and delivers a joinder
agreement to this Amendment substantially in the form attached hereto as Annex B (the “Joinder Agreement”) shall become a party to the Restated Credit Agreement and a “Lender” thereunder and pursuant to such
Joinder Agreement will commit to make Additional Term Loans to the Borrower in an amount equal to the amount of such Person’s “Additional Term Loan Commitment” as set forth in such Joinder Agreement. 

 

	2.3	Each Lender party hereto hereby authorizes the Administrative Agent and the Collateral Agent to enter into the Intercreditor Agreement and the other Credit Documents or
any amendments, amendments and restatements, reaffirmations or modifications with respect thereto, in each case as necessary to reflect the amendments to the Existing Credit Agreement set forth herein and in the Restated Credit Agreement.

 SECTION III. COMMITMENTS AND LOANS 
  

	3.1	Holdings, the Borrower, each other Credit Party, the Administrative Agent and the Lenders party hereto acknowledge and agree that under the Existing Credit Agreement,
the aggregate principal balance of all Term Loans on the Second Amendment Effective Date (as defined below) (without giving effect to this Amendment) (the “Existing Principal Amount”) is $547,250,000.27 (exclusive of
interest, fees and expenses). Holdings, Borrower and each other Credit Party acknowledge and agree that all Obligations outstanding as of the Second Amendment Effective Date (including the Existing Principal Amount) constitute valid and binding
obligations of Holdings, Borrower and the other Credit Parties and are not subject to offset, counterclaim, defense or recoupment of any kind. All interest, fees and expenses together with all other Obligations outstanding under the Existing Credit
Agreement (including the Existing Principal Amount) which remain unpaid and outstanding as of the Second Amendment Effective Date shall be in all respects continuing and remain outstanding and payable under the Restated Credit Agreement and the
other Credit Documents, with only the terms thereof being modified from and after the Second Amendment Effective Date as set forth in this Amendment and the Restated Credit Agreement and the other Credit Documents. 

 

	3.2	Subject to the terms and conditions of this Amendment and the Restated Credit Agreement, each Lender party hereto with an Additional Term Loan Commitment severally
agrees to make, on the Second Amendment Effective Date, an Additional Term Loan to the Borrower in an amount equal to the amount of such Lender’s Second Amendment Effective Date Term Loan Commitment as set forth on Appendix A to the
Restated Credit Agreement. 

  

	3.3	 It is the intention of each of the parties hereto that the Existing Credit Agreement be amended and restated so as to preserve the perfection and
priority of all security interests securing Indebtedness 

  
 2 

	 	
and Obligations under the Existing Credit Agreement and that all Indebtedness and Obligations of Holdings and its Subsidiaries hereunder and thereunder shall be secured by the Collateral
Documents and that this Amendment and the Restated Credit Agreement do not constitute a novation of the Obligations and liabilities existing under the Existing Credit Agreement. The parties hereto further acknowledge and agree that this Amendment
and the Restated Credit Agreement constitute an amendment of the Existing Credit Agreement made under and in accordance with the terms of Section 10.5 of the Existing Credit Agreement. In addition, from and after the Second Amendment
Effective Date, all references to the “Credit Agreement” contained in any Credit Document shall be deemed to refer solely to the Existing Credit Agreement as amended and restated by this Amendment. 

 

	3.4	The Additional Term Loans and the Term Loans existing under the Existing Credit Agreement shall constitute a single Class of Term Loans. On the Second Amendment
Effective Date, (i) the Additional Term Loans shall be Eurodollar Rate Loans, (ii) the Interest Period and Adjusted Eurodollar Rate for the Additional Term Loans shall be the same as that in effect for the existing Term Loans on the Second
Amendment Effective Date, and (iii) the Borrower shall pay all fees accrued to the Second Amendment Effective Date with respect to the existing Term Loans. 

 SECTION IV. CONDITIONS TO EFFECTIVENESS 
 This Amendment shall become
effective as of the date hereof only upon the satisfaction of all of the following conditions precedent (the date of satisfaction of such conditions being referred to herein as the “Second Amendment Effective Date”):

  

	4.1	The Administrative Agent shall have received counterpart signature pages of this Amendment duly executed by each of the Credit Parties, the Administrative Agent and the
Lenders; 

  

	4.2	The Administrative Agent shall have received Notes executed by the Borrower in favor of each Lender or Additional Lender requesting a Note evidencing its Term Loans at
least 3 Business Days prior to the Second Amendment Effective Date;

Section 3.1 of the Restated Credit Agreement; and 

  

	4.4	As of the Second Amendment Effective Date, the representations and warranties contained herein shall be true and correct in all material respects, except to the extent
such representations and warranties specifically relate to an earlier date, in which case such representations and warranties shall have been true and correct in all material respects on and as of such earlier date; provided that in each
case, such materiality qualifier shall not be applicable to any representations or warranties that already are qualified or modified by materiality in the text thereof. 

 SECTION V. REPRESENTATIONS AND WARRANTIES

Administrative Agent and the Lenders to enter into this Amendment and to amend the Existing Credit Agreement in the manner provided herein, each Credit Party which is a party hereto represents and warrants to the Administrative Agent and the Lenders

will be true and correct on and as of the Second Amendment Effective Date to the same extent as though made on and as of that date, except to the extent such representations and warranties specifically relate to an earlier date, in which case they

 5.7 Absence of Default. No event has occurred and is continuing or will
result from the consummation of the transactions contemplated by this Amendment that would constitute an Event of Default or a Default.

 Each Credit Party (other than the Borrower) acknowledges and agrees that (i) notwithstanding the conditions to effectiveness set forth in this Amendment, such Credit Party is not required by the
terms of the Existing Credit Agreement or any other Credit Document to consent to the amendments to the Existing Credit Agreement effected pursuant to this Amendment and Restated Credit Agreement and (ii) nothing in the Existing Credit

7.2 Certain Waivers. Borrower, Holdings and each other Credit Party hereby agrees that neither any Agent nor any Lender shall be liable

claims which are based on the gross negligence or willful misconduct of any Agent or any Lender or any of their respective agents. This section shall survive the execution and delivery of this Amendment and the termination of the Restated Credit
Agreement.

administrative agent (the “Administrative Agent”). 
 RECITALS: 

WHEREAS, reference is hereby made to (i) the Credit and Guaranty Agreement dated as of February 8, 2012 (as amended by
that certain First Amendment to Credit and Guaranty Agreement dated as of May 11, 2012 and as further amended through the date hereof without giving effect to the amendments set forth in the Second Amendment (as defined below), the
“Existing Credit Agreement”) by and among the Borrower, Holdings (as defined below), TRONOX INCORPORATED, a Delaware corporation (“US Holdings”), the subsidiaries of Holdings named therein or
from time to time party thereto, the lenders party thereto, the Administrative Agent and the other agents named therein and (ii) the Second Amendment to Credit and Guaranty Agreement dated as of March 19, 2013 (the “Second

amended, restated, supplemented or otherwise modified from time to time, the “Restated Credit Agreement”)); and 
 WHEREAS, subject to the terms and conditions of the Second Amendment, the Additional Lender shall become a Lender under the Restated Credit Agreement pursuant to this Joinder Agreement; 

NOW, THEREFORE, in consideration of the premises and agreements, provisions and covenants herein contained, the parties hereto
agree as follows: 
 The Additional Lender hereby commits to make a Term Loan to the Borrower on the Second Amendment Effective
Date in the amount of its “Additional Term Loan Commitment” set forth on its signature page hereto; provided that such amount may be reduced at the Administrative Agent’s discretion if the aggregate amount of all commitments
received with respect to the Additional Term Loans exceeds the Additional Term Loan Amount (as defined in the Second Amendment) (such reduced amount, the “Allocated Amount”). Such Term Loan shall be provided subject to all of
the terms and conditions set forth in the Second Amendment. Such Term Loans shall be entitled to all the benefits afforded by the Restated Credit Agreement and the other Credit Documents, and shall, without limiting the foregoing, benefit equally
and ratably from each Guaranty and Liens created by the Collateral Documents. For the avoidance of doubt, the Additional Lender hereby consents to the Second Amendment. 

 

	1 	Each Additional Lender needs to sign a separate Joinder Agreement. 

 The Additional Lender (i) confirms that it has received a copy of the Second Amendment
and the Restated Credit Agreement and the other Credit Documents, together with copies of the financial statements referred to therein and such other documents and information as it has deemed appropriate to make its own credit analysis and decision
to enter into this Agreement; (ii) agrees that it will, independently and without reliance upon the Administrative Agent, the Arrangers or any other Lender or Agent and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action under the Restated Credit Agreement; (iii) appoints and authorizes the Administrative Agent and the Collateral Agent to take such action as agent on its behalf and
to exercise such powers and discretion under the Restated Credit Agreement and the other Credit Documents as are delegated to the Administrative Agent and the Collateral Agent by the terms thereof, together with such powers and discretion as are
reasonably incidental thereto; and (iv) agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Restated Credit Agreement are required to be performed by it as a Lender. 

The Additional Lender acknowledges and agrees that upon its execution of this Agreement that as of the Second Amendment Effective Date,
the Additional Lender shall become a “Lender” under, and for all purposes of, the Restated Credit Agreement and the other Credit Documents, and shall be subject to and bound by the terms thereof, and shall perform all the obligations of
and shall have all rights of a Lender thereunder. 
 Delivered herewith to the Administrative Agent and the Borrower are such
forms, certificates or other evidence with respect to United States federal income tax withholding matters as the Additional Lender may be required to deliver to the Administrative Agent pursuant to Section 2.17(c) of the Restated Credit
Agreement. 
 This Agreement may not be amended, modified or waived except by an instrument or instruments in writing signed and
delivered on behalf of each of the parties hereto. This Agreement, the Restated Credit Agreement and the other Credit Documents constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all
other prior agreements and understandings, both written and verbal, among the parties or any of them with respect to the subject matter hereof. 
 THIS AGREEMENT AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSE OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED HEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 
 Any term or
provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and
provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be
interpreted to be only so broad as would be enforceable. This Agreement may be executed in counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement.
