iation Rights. In general, no taxable income is reportable when a
stock appreciation right is granted to a participant. Upon exercise, the participant generally will recognize ordinary income in an amount equal to the fair market value of any shares received. If the participant is an employee, such ordinary income
generally is subject to withholding of income and employment taxes. Any additional gain or loss recognized upon any later disposition of the shares would be capital gain or loss.

Restricted Stock Awards. A participant acquiring shares of restricted stock generally will recognize ordinary income equal to the fair market value of
the shares on the vesting date. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. The participant may elect pursuant to Section 83(b) of the Code to accelerate the
ordinary income tax event to the date of acquisition by filing an election with the Internal Revenue Service no later than thirty days after the date the shares are acquired. Upon the sale of shares acquired pursuant to a restricted stock award, any
gain or loss, based on the difference between the sale price and the fair market value on the date the ordinary income tax event occurs, will be taxed as capital gain or loss.

Restricted Stock Unit Awards. There are no immediate tax consequences of receiving an award of restricted stock units. A participant who is
awarded restricted stock units generally will be required to recognize ordinary income in an amount equal to the fair market value of the shares issued to and/or the cash received by such participant at the end of the applicable vesting period or,
if later, the settlement date elected by the administrator or a participant. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Any additional gain or loss recognized upon any
later disposition of any shares received would be capital gain or loss.

Performance Shares and Performance Unit Awards. A participant generally
will recognize no income upon the grant of a performance share or a performance unit award. Upon the settlement of such awards, participants normally will recognize ordinary income in the year of receipt in an amount equal to the cash received and
the fair market value of any unrestricted shares received. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of any shares received, any gain or loss, based on
the difference between the sale price and the fair market value on the date the ordinary income tax event occurs, will be taxed as capital gain or loss.
