Explanation of Responses:

( 1 )This amendment to the Form 4 filed on June 7, 2023 does not report any new or additional transactions but is being filed solely to correct the transaction codes and reported pricing. In this regard, all of the reported transactions were open-market purchases at volume weighted average prices but were inadvertently reflected in the original filing as exempt single transactions with the Issuer. The reporting person undertakes to provide to Issuer, any security holder of the Issuer or the SEC, upon request, full information regarding the number of shares purchased at each separate price. ( 2 )These shares are directly owned by the Hume 2012 Irrevocable Children's Trust, dated 11/19/12. The reporting person is an investment advisor to that trust and in that capacity may be deemed to have voting and dispositive power over such shares. ( 3 )These shares are directly owned by the George H Hume Children's Trust dated 1/1/2005 FBO L Hume. The reporting person is an investment advisor to that trust and in that capacity may be deemed to have voting and dispositive power over such 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).
