The Notes were issued under an Indenture, dated November 28, 2018 (the “Base Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, dated November 28, 2018, between the Company and the Trustee (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”).

The Floating Rate Notes may not be redeemed at the Company’s option prior to maturity.

If each of the previously announced separations and distributions of Dow Holdings Inc. and Corteva, Inc. has not been completed on or before May 1, 2020, or, if prior to such date, the Company has abandoned either of the separations or distributions, the Company will be required to redeem each series of Notes at a redemption price equal to 101 % of the principal amount of such series of Notes, plus accrued and unpaid interest, if any, to but excluding the date of redemption.

The Indenture also contains certain limitations on the Company’s ability to incur liens and enter into sale and leaseback transactions, as well as customary events of default.
