vesting of your Stock Units subject to such Award immediately stops and such Award expires immediately as to the number of Stock Units that are not vested as of the date your Service as an Employee or a Consultant terminates. If your Stock Units are
granted in consideration of your Service as an Outside Director, after your Service as an Outside Director terminates for any reason, vesting of your Stock Units subject to such Award immediately stops and such Award expires immediately as to the

result of the termination. This means that the Stock Units will immediately be cancelled.

|[Recoupment of Award to be used only if a performance vesting RSU] |  | If your Stock Unit becomes vested based on the achievement of financial performance criteria and there is a restatement of the Companys financial results which would have
resulted in a lesser number of Stock Units becoming vested, then the Company shall have the right, to the extent permissible under applicable law, to seek recoupment of any amount held by you in excess of the amounts, if any, that would have been
vested based on the actual restated financial results. This right of recoupment shall apply to shares issued in settlement of the Stock Units or the proceeds you receive from the sale of such shares, as applicable.]

the terms of the leave provide for continued service crediting, or when continued service crediting is required by applicable law. But your service terminates when the approved leave ends, unless you immediately return to active work. The Company

future date. As a holder of Stock Units, you have no rights other than the rights of a general creditor of the Company.

Units are settled by issuing shares of the Companys Common Stock. No adjustments will be made for dividends or other rights if the applicable record date occurs before your stock certificate is issued, except as described in the
Plan.

proceeds to the Company for such purpose. You authorize the Company to withhold from any other compensation payable to you to the extent the proceeds from the sale of the Tax Settlement Shares does not satisfy your Tax Withholding
Obligations.
