Agreement or adopt other policies or procedures (including amendments, policies and procedures with retroactive effect), or take any other commercially reasonable actions necessary or appropriate to (i) preserve the intended tax treatment of
the compensation and benefits payable hereunder, to preserve the economic benefits of such compensation and benefits, and/or to avoid less favorable accounting or tax consequences for the Company and/or (ii) to exempt the compensation and
benefits payable hereunder from Section 409A or to comply with the requirements of Section 409A and thereby avoid the application of penalty taxes thereunder; provided, however, that this Section 3.3(a) does not, and
shall not be construed so as to, create any obligation on the part of the Company to adopt any such amendments, policies or procedures or to take any other such actions or to indemnify Employee for any failure to do so.

(b) Notwithstanding anything herein to the contrary, Employee acknowledges and agrees that in the event that any tax is imposed under
Section 409A in respect to any compensation or benefits payable to Employee, whether under this Agreement or otherwise, then (i) the payment of such tax shall be solely Employees responsibility, and (ii) neither the Company, or
their subsidiaries or affiliates, nor any of their respective past or present directors, officers, employees or agents shall have any liability for any such tax.
