3.          Lock-Up.

 

(a)          Stockholder
will not, during the period commencing on the date of the Effective Time of Merger 1 and, subject to the terms set forth herein,

warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Parent Shares, or (2) enter into any

in cash or otherwise.

 

(b)          Notwithstanding
the foregoing, Stockholder may transfer Parent Shares (i) to Affiliates (including, for the avoidance of doubt, if Stockholder
is a corporation, partnership, limited liability company, investment fund, trust or other business entity, such investment funds
or other business entities controlled or managed by, or that controls or manages, or under common management with, the Stockholder)
or charitable organizations; (ii) if Stockholder is an individual, to any member 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 intestacy; (iii) if Stockholder is a corporation,
partnership, limited liability company, investment fund or other business entity, as part of a disposition, transfer or distribution

to a nominee or custodian of a Person or entity to whom a disposition or transfer would be permissible under this clause (b); provided,

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 Agreement by Stockholder could not be
adequately compensated by monetary damages. Accordingly, Stockholder agrees that, (a) it will waive, in any action for
specific performance, the defense of adequacy of a remedy at law, and (b) in addition to any other right or remedy to which
Parent may be entitled, at law or in equity, Parent will be entitled to seek to enforce any provision of this Agreement by a

8.          Severability.
Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction will, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without affecting the validity or enforceability of the remaining provisions

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.

take such other actions as Parent may reasonably request for the purpose of carrying out the transactions contemplated by this
Agreement.

addressed in this Agreement and the Merger Agreement.

 

15.         Non-Exclusivity.
The rights and remedies of Parent hereunder are not exclusive of or limited by any other rights or remedies which Parent may have,
