Term Loan Facility

In connection with the ownership restructure of Dow Silicones on May 31, 2016, Dow Silicones incurred $4.5 billion of indebtedness under a certain third party credit agreement ("Term Loan Facility"). The Company subsequently guaranteed the obligations of Dow Silicones under the Term Loan Facility and, as a result, the covenants and events of default applicable to the Term Loan Facility are substantially similar to the covenants and events of default set forth in the Company's Five Year Competitive Advance and Revolving Credit Facility. In the second quarter of 2017, Dow Silicones exercised a 364-day extension option making amounts borrowed under the Term Loan Facility repayable on May 29, 2018, and amended the Term Loan Facility to include an additional 19-month extension option, at Dow Silicones' election, upon satisfaction of certain customary conditions precedent. On February 8, 2018, Dow Silicones delivered a notice of intent to exercise the 19-month extension option on the Term Loan Facility.
