13.No Service Guaranteed. No provision of this Agreement shall confer any right upon the Participant to continued Service with the Company or any Subsidiary.

14.Code Section 409A Compliance. If any provision of this Agreement would result in the imposition of an additional tax under Code Section 409A and related regulations and Treasury pronouncements (“Section 409A”), that provision will be reformed to avoid imposition of the additional tax, including that any Award subject to Section 409A held by a Specified Employee that is settled by reason of termination of employment (other than death) shall be delayed in payment until the expiration of six months, and no action taken to comply with Section 409A shall be deemed to adversely affect the Participant’s rights to an Award.
