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) Shares vest at the beginning of each calendar quarter ending March 31, 2021; dividends are paid currently.
(2) Each restricted stock award is the economic equivalent of one share of the Company's common stock.
(3) Represents the target number of shares that may be earned based on the achievement of specific performance thresholds pertaining to the Company's return on equity (40%), EBITDA (40%), and completed acquisitions (20%), as defined and set by our compensation committee, over the period from January 1, 2018 through December 31, 2020, with the opportunity to earn up to one third of the award in any one year for performance against the specified measures. However, more or less shares than the target number of shares may be earned based on our performance with the number of shares earned based on achievement of performance between points being interpolated on a linear basis. Furthermore, each of the performance based awards are subject to a modifier, which increases or decreases actual shares earned (both in one year and three years) based on the Company's relative total return to shareholders compared to the SNL Healthcare REIT Index. (continued on footnote 4)
(4) At the end of each of the performance periods, any earned shares during such period will vest on January 1 of the following calendar year. Dividends are paid on these shares only upon achievement of the performance measures.

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