#### Purchase of Common Stock
Each purchase contract that is a component of a Corporate Unit or a Treasury Unit will obligate its holder to purchase, and the Company to issue and deliver, on December 15, 2028 (or if such day is not a business day, the following business day) (the “purchase contract settlement date”), for $50 in cash a number of shares of the Company’s common stock equal to the settlement rate (together with cash, if applicable, in lieu of any fractional shares of common stock in the manner described below), unless the purchase contract terminates prior to that date or is settled early at the holder’s option.

If the applicable market value is the same as the threshold appreciation price, the aggregate market value of the shares issued upon settlement will be equal to the stated amount, assuming that the market price of the common stock on the purchase contract settlement date is the same as the applicable market
