 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.

Section409A of the Code. Section 409A of the Code (referred to as “Section 409A”) provides certain requirements for non-qualified deferred compensation arrangements with respect to an individual’s deferral and distribution elections and permissible distribution events. Awards granted
under the Amended and Restated Plan with a deferral feature will be subject to the requirements of Section 409A. If an award is subject to and fails to satisfy the requirements of Section 409A, the recipient of that award may recognize
ordinary income on the amounts deferred under the award, to the extent vested, which may be prior to when the compensation is actually or constructively received. Also, if an award that is subject to Section 409A fails to comply with
Section 409A’s provisions, Section 409A imposes an additional 20% federal income tax on compensation recognized as ordinary income, as well as interest on such deferred compensation.

Medicare Surtax. In addition, a participant’s annual “net investment income”, as defined in Section 1411 of the Code, may be
subject to a 3.8% federal surtax. Net investment income may include capital gain and/or loss arising from the disposition of shares issued pursuant to awards granted under the Amended and Restated Plan. Whether a participant’s net investment
income will be subject to this surtax will depend on the participant’s level of annual income and other factors.
