Explanation of Responses:

( 1 )The original Form 4, filed on May 8, 2018, is being amended by this Form 4 amendment solely to correct an administrative error, which misreported the Amount of Securities Beneficially Owned Following Reported Transaction as 499,837; however, the correct balance was 496,837. ( 2 )The original Form 4 filed March 20, 2019 is being amended by this Form 4 amendment solely to correct an administrative error, which misreported a purchase of 3,000 shares when in fact this is a duplicate of a previous purchase. As a result of this administrative error, the number of shares beneficially owned by the reporting person following the corrected transaction reflects an decrease in the number of shares reported as beneficially owned by the reporting person by 3,000 shares.

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).
