For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if a Stockholder is a corporation, limited liability company, partnership or trust, the corporation, limited liability company, partnership or trust it may transfer the Subject Share to any wholly-owned subsidiary of such corporation, limited liability company or partnership or to the stockholders, partners, members or beneficiaries of the Stockholder, provided, however, that in any such case, it shall be a condition to the transfer that (i) the transferee execute an agreement stating that the transferee is receiving and holding such Subject Shares subject to the provisions of this Section 5.3 and there shall be no further transfer of such Subject Shares except in accordance with this Section 5.3 (and, for the avoidance of doubt, the provisions of this Section 5.3, including the exception to transfer restrictions shall apply to any such transferee as if the transferee were the original recipient of the Subject Shares hereto), (ii) that any such transfer shall not involve a disposition for value, and (iii) that no public announcement or filing under the Exchange Act shall be required of or voluntarily made by or on behalf of the Stockholder or Parent in connection with any such transfer. In addition, notwithstanding anything herein to the contrary, nothing herein shall prevent the Stockholder from establishing a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act (a “10b5-1 plan”), relating to the sale of the Stockholder’s Subject Shares, provided that (i) such shares may not be sold until after 180 days following the Commencement Date, (ii) the aggregate number of shares sold by the Stockholder under a 10b5-1 plan or otherwise shall not exceed the limitations set forth in this Section 5.3 and (iii) the establishment of such plan will not result in any public filing or other public announcement of the Stockholder during the 180 days following the Commencement Date.
