Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	These shares are represented by a restricted stock unit award bearing the right to receive Common Shares and are scheduled to vest in two equal installments on December 31, 2019 and December 31, 2020.
(2)	This reflects the target number of performance-based restricted stock units awarded. Actual awards may vary from as low as zero to as high as 2.5 times the target. As soon as reasonably practicable following the end of the Performance Period (beginning on January 1, 2019 and ending on December 31, 2020) and in no event later than March 15, 2021, the number of shares that may ultimately be earned will be determined and issued.
(3)	Based on the Company performance during the two-year performance period ending December 31, 2018, approximately 86.55% of the performance-based restricted stock units vested(as previously disclosed the reporting person had the opportunity to earn up to 250% of the number originally reported).
(4)	These shares are being withheld to cover taxes related to the vesting of performance-based restricted stock units.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
