Explanation of Responses:

( 1 )Grant of time-based restricted shares pursuant to the Company's 2017 Omnibus Incentive Plan. These restricted shares vest one-third each on April 1, 2024, 2025 and 2026. ( 2 )Grant of performance-based restricted shares pursuant to the Company's 2017 Omnibus Incentive Plan. All or a portion of these restricted shares will vest over a three-year period upon the satisfaction of certain performance goals established by the Compensation Committee for the year ending December 31, 2023. ( 3 )This amended Form 4 is being filed to correct an administrative error which misreported the number of time-based and performance-based restricted shares granted to the Reporting Person. The original Form 4 reported that 2,044 time-based and 2,044 performance-based restricted shares were granted when 2,271 time-based and 2,271 performance-based restricted shares were granted. As a result of this administrative error, the number of shares beneficially owned by the reporting person following the corrected transactions reflects an increase in the number of shares reported as beneficially owned by the reporting person by 454 shares.

Remarks: Pursuant to Instruction 9 to Form 4, the Reporting Person has omitted from this amendment to the Form 4 the transaction information with respect to the other shares of the Issuer that were reported in the initial filing of the Form 4 and which are not being amended hereby.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.

* 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).
