(b)              
Notwithstanding the foregoing, Stockholder may transfer Parent Shares (i) to Affiliates (including,

of Stockholder’s immediate family, or to a trust for the benefit of Stockholder or any member of Stockholder’s immediate
family for estate planning purposes or for the purposes of personal tax planning, or upon the death of Stockholder, by will or

Specific Performance. Stockholder acknowledges that Parent could be damaged irreparably
if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this

Consent to Jurisdiction. Any suit, action or proceeding seeking to enforce any provision
of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby or thereby

appellate courts therefrom) in any suit, action or proceeding and irrevocably waives, to the fullest extent permitted by applicable
Law, any objection which it may now or hereafter have to the laying of the venue of any suit, action or proceeding in any of those
courts or that any suit, action or proceeding which is brought in any of those courts has been brought in an inconvenient forum.
Process in any suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction
of any of the named courts. Without limiting the foregoing, each party agrees that service of process on it by notice as provided
in Section 7 will be deemed effective service of process. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT,
TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

11.             
Waiver. The rights and remedies of the parties to this Agreement are cumulative and
not alternative. Neither any failure nor any delay by a party in exercising any right, power or privilege under this Agreement
or any of the documents referred to in this Agreement will operate as a waiver of such right, power or privilege, and no single
or partial exercise of any such right, power or privilege will preclude any other or further exercise of such right, power or privilege
or the exercise of any other right, power or privilege. To the maximum extent permitted by applicable Law, (a) no claim or right
arising out of this Agreement or any of the documents referred to in this Agreement can be discharged by one party, in whole or
in part, by a waiver or renunciation of the claim or right unless in a written document signed by the other party, (b) no waiver
that may be given by a party will be applicable except in the specific instance for which it is given, and (c) no notice to or
demand on one party will be deemed to be a waiver of any obligation of that party or of the right of the party giving such notice
or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.

Time of Merger 1 and shall automatically terminate in the event of the termination of the Merger Agreement for any reason.

13.             
Further Assurances. Stockholder shall execute and/or cause to be delivered to Parent
such instruments and other documents and shall take such other actions as Parent may reasonably request for the purpose of carrying
out the transactions contemplated by this Agreement.

14.

documents delivered by the parties in connection herewith constitute the entire agreement among the parties with respect to the
subject matter hereof and supersede all prior agreements and understandings, both written and oral, between the parties with respect
to its subject matter and constitute (along with the documents delivered pursuant to this Agreement) a complete and exclusive statement
