Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.
On April 20, 2021, Kronos Worldwide, Inc. (the "Company"), Kronos Louisiana, Inc. "(Kronos Louisiana"), Kronos (US), Inc. ("Kronos US"),
      Kronos Canada, Inc. ("Kronos Canada"), Kronos Europe NV ("Kronos Europe"), and Kronos Titan GmbH ("Kronos Titan," and together with Kronos Louisiana, Kronos US, Kronos Canada, and Kronos Europe, the "Subsidiaries"), each a direct or indirect
      operating subsidiary of the Company, entered into that certain Credit Agreement with Wells Fargo Bank, National Association, as administrative agent and lender, providing for a new global $225 million asset-based revolving credit facility (the
      "Global Revolver"). The Global Revolver, which may be used for general corporate purposes, concurrently refinances and replaces the Company's $125 million North American revolving credit facility with Wells Fargo Capital Finance, LLC, as agent, and
      the
€120 million European revolving credit facility (the "European Revolver") in favor of certain of the Company's subsidiaries with
Deutsche Bank Luxembourg S.A.,
      as agent. Among other things, the Global Revolver:
•
provides for revolving borrowings by the Company and the Subsidiaries in amounts up to $225 million through April 2026 (with revolving borrowings
                by Kronos Canada, Kronos Europe and Kronos Titan limited to CDN25 million, €30 million and €60 million, respectively), with available borrowings based on formula-determined amounts of eligible trade receivables and inventories of the
                borrowers (less any outstanding letters of credit issued under the Global Revolver);
•
bears interest, at the Company's option, at the applicable non-base rate (LIBOR, CDOR or EURIBOR, dependent upon currency of the borrowing) plus
                a margin ranging from 1.5% to 2.0%, or at the applicable base rate plus a margin ranging from 0.5% to 2.0%. Euro denominated borrowings are subject to a 0.25% EURIBOR floor, plus the applicable margin. The applicable margin in respect of
                borrowings under the Global Revolver are determined based upon, initially the passage of time, and thereafter upon average availability under the facility;
•
requires a payment of an unused fee to the lender of either 0.25% or 0.375%, determined initially by the passage of time, and thereafter upon
                average facility usage. In addition, the Global Revolver requires the payment of customary agency and administrative fees;
•
is collateralized by, among other things, a first priority lien on the trade receivables and inventories of the Company and the Subsidiaries;
•
contains a number of covenants and restrictions which, among other things, limits the ability of the Company and the Subsidiaries under certain
                circumstances to incur additional debt, incur liens, pay additional dividends or merge or consolidate with, sell or transfer all or substantially all of the Company's Subsidiaries' assets to, another entity, and under certain conditions
                requires the maintenance of a specified financial covenant (fixed charge coverage ratio, as defined in the Global Revolver) to be at least 1.0 to 1.0; and
•
contains customary default provisions, including a cross-default with any other indebtedness of the Company and its subsidiaries in excess of $20
                million.
In addition, pursuant to the Guaranty and Security Agreement, dated April 20, 2021, by and among the Company, Kronos Louisiana, Kronos
      US and Kronos International, Inc., a direct subsidiary of the Company, each of the parties thereto have agreed to guaranty the obligations of all parties to the Global Revolver, other than the obligations of Kronos Canada.
