“3.4    Account Adjustments

For periods prior to July 26, 2016, each Payment Sub-Account shall be credited with additional whole or fractional Stock Units for cash dividends paid on the Common Stock based on the number of Stock Units in the Payment Sub-Account on the applicable dividend record date and calculated based on the Fair Market Value of the Common Stock on the applicable dividend payment date. Notwithstanding any provision of the Plan to the contrary, effective July 26, 2016 and thereafter, each Payment Sub-Account shall be credited with additional cash for the cash dividends paid on the Common Stock based on the number of Stock Units in the Payment Sub-Account on the applicable dividend record date. This additional cash credited to the Payment
