NOW, THEREFORE, in

3.          Prohibitions
on Transfer and Sale. This Award (including any additional RSUs received by the Participant as a result of stock dividends,
stock splits or any other similar transaction affecting the Company's securities without receipt of consideration) shall not be
transferable by the Participant otherwise than (i) by will or by the laws of descent and distribution, or (ii) pursuant to a qualified

by operation of law or otherwise) and shall not be subject to execution, attachment or similar process. Any attempted transfer,
assignment, pledge, hypothecation or other disposition of this Award or of any rights granted hereunder contrary to the provisions
of this Section 3, or the levy of any attachment or similar process upon this Award shall be null and void.

4.          Adjustments.
The Plan contains provisions covering the treatment of RSUs and shares of Common Stock in a number of contingencies such as stock
splits. Provisions in the Plan for adjustment with respect to this Award and the related provisions with respect to successors
to the business of the Company are hereby made applicable hereunder and are incorporated herein by reference.



5.          Securities
Law Compliance. The Participant specifically acknowledges and agrees that any sales of shares of Common Stock shall be made
in accordance with the requirements of the Securities Act of 1933, as amended. The Company
currently has an effective registration statement on file with the Securities and Exchange Commission with respect to the Common
Stock to be granted hereunder. The Company intends to maintain this registration statement but has no obligation to do so. If the
registration statement ceases to be effective for any reason or there is a restriction under foreign law, a Participant will not
be able to transfer or sell any of the shares of Common Stock issued to the Participant pursuant to this Agreement unless exemptions
from registration or filings under applicable securities laws are available. Furthermore, despite registration, applicable securities
laws may restrict the ability of the Participant to resell his or her Common Stock, including due to the Participant’s affiliation
with the Company. The Company shall not be obligated to either issue the Common Stock or permit the resale of any shares of Common
Stock if such issuance or resale would violate any applicable securities law, rule or regulation.



6.          Rights
as a Stockholder. The Participant shall have no right as a stockholder, including voting and dividend rights, with respect
to the RSUs subject to this Agreement.



7.          Incorporation
of the Plan. The Participant specifically understands and agrees that the RSUs and the shares of Common Stock to be issued
under the Plan will be issued to the Participant pursuant to the Plan, a copy of which Plan the Participant acknowledges he or
she has read and understands and by which Plan he or she agrees to be bound. The provisions of the Plan are incorporated herein
by reference.



8.          Tax
Liability of the Participant and Payment of Taxes.The Participant acknowledges and agrees that any income or other
taxes due from the Participant with respect to this Award or the shares of Common Stock to be issued pursuant to this Agreement
or otherwise sold shall be the Participant’s responsibility. Without limiting the foregoing, the Participant agrees that
if under applicable law the Participant will owe taxes at each vesting date on the portion of the Award then vested the Company
shall be entitled to immediate payment from the Participant of the amount of any tax required to be withheld by the Company. Any
taxes due shall be paid, at the option of the Company as follows:



(a)          through
reducing the number of shares of Common Stock entitled to be issued to the Participant on the applicable vesting date in an amount
equal to the amount of minimum withholding tax due and payable by the Company. Fractional shares will not be retained to satisfy
any portion of the withholding tax. Accordingly, the Participant agrees that in the event that the amount of withholding tax owed
would result in a fraction of a share being owed, that amount will be satisfied by withholding the fractional amount from the Participant’s
paycheck;



(b)          requiring
the Participant to deposit with the Company an amount of cash equal to the amount determined by the Company to be required with
respect to the statutory minimum of the Participant’s estimated total federal, state and local tax obligations or otherwise
withholding from the Participant’s paycheck an amount equal to the withholding tax due and payable; or



4







(c)          if
the Company believes that the sale of shares can be made in compliance with applicable securities laws, authorizing, at a time
when the Participant is not in possession of material nonpublic information, the sale by the Participant on the applicable vesting
date of such number of shares of Common Stock as the Company instructs a registered broker to sell to satisfy the Company’s
withholding obligation, after deduction of the broker’s commission, and the broker shall be required to remit to the Company
the cash necessary in order for the Company to satisfy its withholding obligation. To the extent the proceeds of such sale exceed
the Company’s tax withholding obligation the Company agrees to pay such excess cash to the Participant as soon as practicable.
In addition, if such sale is not sufficient to pay the Company’s tax withholding obligation the Participant agrees to pay
to the Company as soon as practicable, including through additional payroll withholding, the amount of any tax withholding obligation
that is not satisfied by the sale of shares of Common Stock. The Participant agrees to hold the Company and the broker harmless
from all costs, damages or expenses relating to any such sale. The Participant acknowledges that the Company and the broker are
under no obligation to arrange for such sale at any particular price. In connection with such sale of shares of Common Stock, the
Participant shall execute any such documents requested by the broker in order to effectuate the sale of shares of Common Stock
and payment of the withholding obligation to the Company. The Participant acknowledges that this paragraph is intended to comply
with Section 10b5-1(c)(1(i)(B) under the Exchange Act.



The Company shall not
deliver any shares of Common Stock to the Participant until it is satisfied that all required withholdings have been made.

Participant (i) authorizes the Company and its Affiliates or, if the Participant is not employed by the Company or an Affiliate,
his or her employer, to furnish the Company and its Affiliates (and any agent administering the Plan or providing recordkeeping
