(a) such stock options and awards are granted in accordance with the terms and conditions of the 2022 Stock Incentive Plan; and

We consent to the use of this opinion as an exhibit to the Registration Statement and further consent to the use of our name wherever appearing in the Registration Statement, including the Prospectus constituting a part thereof, and in any amendment thereto.

Yours truly,
