You may make optional cash
investments by sending a check (in U.S. dollars) made payable to “Broadridge” along with a completed Direct Share Purchase
and Enrollment Form/Coupon which is attached to each statement you receive.

As an added security measure,
Broadridge applies a five (5) business day hold period to the initial association of banking account information to your investor
account as well as changes made to established direct deposit or direct debit instructions. This hold period helps prevent unauthorized
transactions.

In the event purchases are
made in the open market, Broadridge will submit your request to the registered broker-dealer utilized by the Program to purchase whole
shares and allocate any fractional shares to equal each amount you invest, less any applicable fees. Keep in mind that the value of the
stock can fluctuate.

The past performance of Common
Stock is not necessarily an indicator of future performance. There can be no guarantee that the stock you purchase through the Plan will
increase in value or retain its current value.
