        (as defined in the Indenture referred to herein) and Wilmington Trust, National Association, a national banking association, as trustee under the Indenture referred to below (the “Trustee”).

       

      W I T N E S S E T H

       

      WHEREAS, the Issuer has heretofore executed and delivered to the Trustee an indenture dated as of September 22, 2017 (the “Base Indenture”), among the
        Issuer, the Guarantors party thereto (as defined therein) and the Trustee, providing for the issuance of 5.750% Senior Notes due 2025 (the “Notes”);

       

      WHEREAS, the Issuer has heretofore executed and delivered to the Trustee a first supplemental indenture, dated as of April 1, 2019 (the “First Supplemental
          Indenture”), among Tronox Holdings PLC, Tronox Investment Holdings Limited and Tronox UK Merger Company Limited, as new guarantors, the Issuer, the other Guarantors party thereto (as defined therein) and the Trustee, to accede certain new
        guarantors under the Notes;

       

      WHEREAS, the Issuer has heretofore executed and delivered to the Trustee a second supplemental indenture, dated as of April 12, 2019 (the “Second Supplemental
          Indenture”), among Cristal Inorganic Chemicals Netherlands B.V. and Cristal International B.V., as new guarantors, the Issuer, the other Guarantors party thereto (as defined therein) and the Trustee, to accede certain new guarantors under
        the Notes (the Base Indenture, as supplemented by each of the First Supplemental Indenture and the Second Supplemental indenture, herein referred to as the “Indenture”);

       

      WHEREAS, the Indenture provides that under certain circumstances each Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which each such
        Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuer’s obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and

       

      WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

       

      NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, each Guaranteeing Subsidiary and the Trustee mutually
        covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

       

      1.          Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

       

      2.          Agreement to Guarantee. Each Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the
        conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article 10 thereof.

       

      3.         No Recourse Against Others. No director, manager, officer, employee, incorporator, stockholder or member of Holdings, the Issuer or any
        Subsidiary thereof will have any liability for any obligations of Holdings, the Issuer or the Guarantors under the Notes, this Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their
        creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal
        securities laws.

      5.          Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy will be an original, but all of
        them together represent the same agreement. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Supplemental Indenture as to the
        parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.
