On November 20, 2014, PPG Industries, Inc. (the “Company”) entered into a Term Loan Agreement among the Company, Sumitomo Mitsui Banking Corporation, as Administrative Agent, and Sumitomo Mitsui Banking Corporation, as Initial Lender (the “Credit Agreement”). The Credit Agreement provides for a €500,000,000 unsecured term loan facility. The Credit Agreement will terminate and all amounts outstanding thereunder will be due and payable on November 20, 2017. The Company expects to complete a single borrowing of €500,000,000 pursuant to the Credit Agreement within ten business days. The Credit Agreement provides that loans will bear interest at rates based on the Eurocurrency Rate, as defined in the Credit Agreement, plus a margin of 0.675% per annum.

The Credit Agreement contains usual and customary restrictive covenants for facilities of its type, which include, with specified exceptions, limitation on the Company’s ability to create liens or other encumbrances, to enter into sale and leaseback transactions and to enter into consolidations, mergers or transfer of all or substantially all of its assets. The Credit Agreement also requires the Company to maintain a ratio of Total Indebtedness to Total Capitalization, as defined in the Credit Agreement, of 60% or less.

The Credit Agreement contains, among other things, customary events of default that would permit the lenders to accelerate the loans, including the failure to make timely payments when due under the Credit Agreement or other material indebtedness, the failure to satisfy covenants contained in the Credit Agreement, a change in control of the Company and specified events of bankruptcy and insolvency.
