Plan and withhold any amounts otherwise payable to the Entitled Executive pursuant to the Plan and/or (ii) require the Entitled Executive to pay to the Corporation an amount in cash up to (but not in excess of) any amounts paid out by the

other benefit or for any other reason, in a manner consistent with the 409A Guidance, if applicable.
