NOW, THEREFORE, the parties hereto agree
as follows:

 

		1.	ENGAGEMENT: Client agrees to engage Consultant under the terms of this Agreement, and Consultant
agrees to accept such engagement. Consultant, or its representative shall be available to Client according to the time or the projects
specified in Exhibit A, attached hereto and made a part of this Agreement by reference herein.

 

		2.	TERM AND TERMINATION: Consultant's engagement pursuant to this Agreement shall commence
on April 20, 2015 and continue until April 30, 2016, unless terminated earlier, as provided herein (the "Term"). At the
end of the Term, this Agreement shall automatically be extended for periods of three (3) months each, unless one party gives the
other party one (1) months' notice of their intent to not extend the Agreement. Other than for the reasons described in Section
4, below, either party may terminate this Agreement during the Term, or any extensions thereof, by giving the other party one (1)
months' written notice of their intent to so terminate.

		4.	PERSONNEL: Client and Consultant agree that Consultant is not in the business of providing
a recruiting or placement service for permanent positions. However, if Client wishes to offer employment to any of Consultant’s
representatives, and if the representative wishes to accept such employment, Consultant has the right to invoice Client, and Client
will promptly pay, a fee as shown in the following table:

 

	Period after the Effective Date of the Agreement	 	% of estimated first
 year’s compensation**	 
	Within the first six (6) months	 	 	100	%
	Between seven (7) months and nine (9) months	 	 	85	%
	After the commencement of the tenth (10th) month	 	 	70	%

 

** For purposes of this Agreement,
“estimated first year’s compensation” shall be defined to include first year’s annualized salary, first
year’s estimated annualized bonus, and number of shares of Client’s stock to be vested to Consultant’s representative
by the first anniversary of representative’s employment by Client. In the case of equity, a warrant shall be issued to Consultant
for the percentage of representative’s shares, at the same price as those as the representative. Equity considered “vested”
shall be determined as a function of the passage of time (i.e. disregarding cliffs and other vesting deferral mechanisms built
into the representative’s option plan).

Client and Consultant also agree
that the Client shall not offer any of Consultant’s Representative (including all Exhibits, and whether or not Consultant’s
Representative remains an employee of Consultant) a consulting or other non-permanent form of employment or engagement within twenty-
four (24) months of termination of Client’s engagement with Consultant, without obtaining the express and written consent
of Consultant. In the absence of this approval, Consultant has the right to invoice Client, and Client will promptly pay, a fee
equal to 100% of the total amount paid by Client to the Consultant’s former Representative for the greater of the duration
of the project or until the time which is twenty-four (24) months after the termination of the Agreement.

 

		5.	INVOICING AND PAYMENT: Consultant shall invoice Client as of the fifteenth
and last day of each month for services performed pursuant to this Agreement. Client shall pay Consultant's invoice, in full,
within five (5) business days of the date of Consultant's invoice. If Client does not pay Consultant pursuant to these terms,
Consultant shall have the right to receive a retainer, as described in Paragraph 6, below.

 

		6.	RETAINER: If Consultant has the right, pursuant to Paragraph 5, above, to receive
a retainer from Client, and further, if Consultant requests such retainer, Client shall pay Consultant a retainer (the "Retainer")
upon written demand from Consultant. Such retainer shall approximate Consultant's best estimate of one half months’ worth
of Consultant's charges working on Client's matters. Client agrees that such retainer shall be replenished to an amount equal
to the following one half month's projected amount due for projected services during such period. Any retainer remaining shall
be applied against the final invoice pursuant to this Agreement.

 

    	Page 2 of 5

    	 

    

		7.	STATUS: Consultant is engaged by Client as an independent contractor, and not
as an employee. As such, Consultant is solely responsible for and will make proper and timely payment of any and all taxes on
amounts paid by Client, including, if applicable, estimated state and federal income taxes, self-employment taxes, state disability
insurance taxes and the like. Neither Consultant nor Consultant’s Representative will receive or participate in any of Client's
employee health insurance or any other employee fringe benefit programs, and Consultant will not be covered by Client's workers'
compensation and other insurance policies.

 

		8.	PROPRIETARY INFORMATION AND INVENTIONS: Consultant understands that certain
proprietary information of Client's may be disclosed to Consultant during the term of this Agreement. Unless such information
was known to Consultant prior to such disclosure, or becomes part of the public domain, or disclosure is required by government-compelled
process, Consultant agrees not to disclose such information to third parties for a period of twenty four months, without prior
written consent of the Client. Consultant acknowledges that, if requested by Client, Consultant will sign an additional and separate
Non-Disclosure Agreement with Client.

 

		9.	NO AUTHORITY: Consultant does not have, and is not granted by this Agreement,
any express or implied right or authority to assume or create any obligations on behalf of, or in the name of, Client; or to bind
Client to, or enter into, directly or indirectly, any contract, agreement or undertaking with any third party. If Client wishes
to grant such authority to Consultant, Client shall issue such authority to Consultant in writing prior to Consultant taking any
such action.

 

		10.	INDEMNITY: Client shall offer the same level of indemnification to Consultant
as Client would normally provide to its officers and directors, including such resolutions by its Board of Directors as are customary
regarding officer and director indemnification. Client shall cause Consultant, and Consultant’s Representative #1 to be
named as a named insureds on it Directors and Officer’s Liability policy.

 

		11.	MISCELLANEOUS:

 

A.          ASSIGNMENT: This Agreement
may not be assigned by either party hereto without the prior written consent of the other.

 

B.           ADDITIONAL PERSONNEL:

only be used after Client has agreed in writing to: (a) such addition; (b) the compensation for such addition; (c) the term of
such addition, and (d) such addition is made a part of this Agreement by an amendment to Exhibit A and executed by both parties.

SECTION 1.
Acquisition Of Shares.

 

(a)

to transfer to the Transferee the number of Transferred Shares set forth in the Summary of Stock Grant. The transfer shall occur
at the offices of the Company on the date of transfer set forth in the Summary of Stock Grant or at such other place and time as
the parties may agree.

 

(b)              
Consideration. The Transferee and the Company agree that the Transferred Shares are being issued to the Transferee
as consideration for a portion of the services performed by the Transferee for the Company. The value of such portion is agreed
to be not less than 100% of the Fair Market Value of the Transferred Shares.

 

(c)               
Stock Plan and Defined Terms. The transfer of the Transferred Shares is subject to the Plan, a copy of which the
Transferee acknowledges having received. The provisions of the Plan are incorporated into this Agreement by this reference. Except
as otherwise defined in this Agreement (including without limitation Section 11 hereof), capitalized terms shall have the meaning
ascribed to such terms in the Plan.

 

SECTION 2.
Forfeiture Condition.

 

(a)               
Scope of Forfeiture Condition. All Transferred Shares initially shall be Restricted Shares and shall be subject to
forfeiture to the Company. The Transferee shall not transfer, assign, encumber or otherwise dispose of any Restricted Shares without
the Company’s written consent, except as provided in the following sentence. The Transferee may transfer Restricted Shares
to one or more members of the Transferee’s Immediate Family or to a trust established by the Transferee for the benefit of
the Transferee and/or one or more members of the Transferee’s Immediate Family, provided in either case that the Transferee
agrees in writing on a form prescribed by the Company to be bound by all provisions of this Agreement. If the Transferee transfers
any Restricted Shares, then this Agreement shall apply to the Subsequent Transferee to the same extent as to the Transferee.

 

(b)              
Vesting. The Forfeiture Condition shall lapse and the Restricted Shares shall become vested in accordance with the
vesting schedule set forth in the Summary of Stock Grant.

 

(c)               
Execution of Forfeiture. The Forfeiture Condition shall be applicable only if the Transferee’s Service terminates
for any reason, with or without cause, including (without limitation) death or disability, before all Restricted Shares have become
vested. In the event that the Transferee’s Service terminates for any reason, the certificate(s) representing any remaining
Restricted Shares shall be delivered to the Company. The Company shall make no payment for Restricted Shares that are forfeited.

 

    	 

    	 

    

 

(d)              
Additional or Exchanged Securities and Property. In the event of a merger or consolidation of the Company, a sale
of all or substantially all of the Company’s stock or assets, any other corporate reorganization, the declaration of a stock
dividend, the declaration of an extraordinary dividend payable in a form other than stock, a spin-off, a stock split, an adjustment
in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding securities, any securities
or other property (including cash or cash equivalents) that are by reason of such transaction exchanged for, or distributed with
respect to, any Restricted Shares or into which such Restricted Shares thereby become convertible shall immediately be subject
to the Forfeiture Condition. Appropriate adjustments to reflect the exchange or distribution of such securities or property shall
be made to the number and/or class of the Restricted Shares.

 

(e)               
Termination of Rights as Stockholder. If Restricted Shares are forfeited in accordance with this Section 2,
then the person who is to forfeit such Restricted Shares shall no longer have any rights as a holder of such Restricted Shares.
Such Restricted Shares shall be deemed to have been forfeited in accordance with the applicable provisions hereof, whether or not
the certificate(s) therefor have been delivered as required by this Agreement.

 

(f)               
Escrow. Upon issuance, the certificates for Restricted Shares shall be deposited in escrow with the Company to be
held in accordance with the provisions of this Agreement. Any new, substituted or additional securities or other property described
in Subsection (d) above shall immediately be delivered to the Company to be held in escrow, but only to the extent the Transferred
Shares are at the time Restricted Shares. All regular cash dividends on Restricted Shares (or other securities at the time held
in escrow) shall be paid directly to the Transferee and shall not be held in escrow. Restricted Shares, together with any other
assets or securities held in escrow hereunder, shall be (i) surrendered to the Company for forfeiture and cancellation in
the event that the Forfeiture Condition or Right of First Refusal applies or (ii) released to the Transferee upon the Transferee’s
request to the extent the Transferred Shares are no longer Restricted Shares (but not more frequently than once every six months).
In any event, all Transferred Shares that have vested (and any other vested assets and securities attributable thereto) shall be
released within 60 days after the earlier of (i) the termination of the Transferee’s Service or (ii) the lapse
of the Right of First Refusal.

 

(g)              
Part-Time Employment and Leaves of Absence. If the Transferee commences working on a part-time basis, then the Company
may adjust the vesting schedule set forth in the Summary of Stock Grant. If the Transferee goes on a leave of absence, then the
Company may adjust the vesting schedule set forth in the Summary of Stock Grant in accordance with the Company’s leave of
absence policy or the terms of such leave. Except as provided in the preceding sentence, Service shall be deemed to continue while
the Transferee is on a bona fide leave of absence, if (i) such leave was approved by the Company in writing and (ii) continued
crediting of Service is expressly required by the terms of such leave or by applicable law (as determined by the Company). Service
shall be deemed to terminate when such leave ends, unless the Transferee immediately returns to active work.

 

    	2

    	 

    

 

SECTION 3.
Right Of First Refusal.

 

(a)               
Right of First Refusal. In the event that the Transferee proposes to sell, pledge or otherwise transfer to a third
party any Transferred Shares, or any interest in Transferred Shares, the Company shall have the Right of First Refusal with respect
to all (and not less than all) of such Transferred Shares. If the Transferee desires to transfer Transferred Shares, the Transferee
shall give a written Transfer Notice to the Company describing fully the proposed transfer, including the number of Transferred
Shares proposed to be transferred, the proposed transfer price, the name and address of the proposed Subsequent Transferee and
proof satisfactory to the Company that the proposed sale or transfer will not violate any applicable federal, State or foreign
securities laws. The Transfer Notice shall be signed both by the Transferee and by the proposed Subsequent Transferee and must
constitute a binding commitment of both parties to the transfer of the Transferred Shares. The Company shall have the right to
purchase all, and not less than all, of the Transferred Shares on the terms of the proposal described in the Transfer Notice (subject,
however, to any change in such terms permitted under Subsection (b) below) by delivery of a notice of exercise of the Right
of First Refusal within 30 days after the date when the Transfer Notice was received by the Company.

 

(b)              
Transfer of Shares. If the Company fails to exercise its Right of First Refusal within 30 days after receiving
the Transfer Notice, the Transferee may, not later than 90 days after the Company received the Transfer Notice, conclude a
transfer of the Transferred Shares subject to the Transfer Notice on the terms and conditions described in the Transfer Notice,
provided that any such sale is made in compliance with applicable federal, State and foreign securities laws and not in violation
of any other contractual restrictions to which the Transferee is bound. Any proposed transfer on terms and conditions different
from those described in the Transfer Notice, as well as any subsequent proposed transfer by the Transferee, shall again be subject
to the Right of First Refusal and shall require compliance with the procedure described in Subsection (a) above. If the Company
exercises its Right of First Refusal, the parties shall consummate the sale of the Transferred Shares on the terms set forth in
the Transfer Notice within 60 days after the Company received the Transfer Notice (or within such longer period as may have
been specified in the Transfer Notice); provided, however, that in the event the Transfer Notice provided that payment for the
Transferred Shares was to be made in a form other than cash or cash equivalents paid at the time of transfer, the Company shall
have the option of paying for the Transferred Shares with cash or cash equivalents equal to the present value of the consideration
described in the Transfer Notice.

 

(c)               
Additional or Exchanged Securities and Property. In the event of a merger or consolidation of the Company, a sale
of all or substantially all of the Company’s stock or assets, any other corporate reorganization, a stock split, the declaration
of a stock dividend, the declaration of an extraordinary dividend payable in a form other than stock, a spin-off, an adjustment
in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding securities, any securities
or other property (including cash or cash equivalents) that are by reason of such transaction exchanged for, or distributed with
respect to, any Transferred Shares subject to this Section 3 shall immediately be subject to the Right of First Refusal. Appropriate
adjustments to reflect the exchange or distribution of such securities or property shall be made to the number and/or class of
the Transferred Shares subject to this Section 3.

    	3

    	 

    

 

(d)              
Termination of Right of First Refusal. Any other provision of this Section 3 notwithstanding, in the event that
the Stock is readily tradable on an established securities market when the Transferee desires to transfer Transferred Shares, the
Company shall have no Right of First Refusal, and the Transferee shall have no obligation to comply with the procedures prescribed
by Subsections (a) and (b) above.

 

(e)               
Permitted Transfers. This Section 3 shall not apply to (i) a transfer by beneficiary designation, will
or intestate succession or (ii) a transfer to one or more members of the Transferee’s Immediate Family or to a trust
established by the Transferee for the benefit of the Transferee and/or one or more members of the Transferee’s Immediate
Family, provided in either case that the Transferee agrees in writing on a form prescribed by the Company to be bound by all provisions
of this Agreement. If the Transferee transfers any Transferred Shares, either under this Subsection (e) or after the Company
has failed to exercise the Right of First Refusal, then this Agreement shall apply to the Subsequent Transferee to the same extent
as to the Transferee.

 

(f)               
Termination of Rights as Stockholder. If the Company makes available, at the time and place and in the amount and
form provided in this Agreement, the consideration for the Shares to be purchased in accordance with this Section 3, then
after such time the person from whom such Shares are to be purchased shall no longer have any rights as a holder of such Shares
(other than the right to receive payment of such consideration in accordance with this Agreement). Such Shares shall be deemed
to have been purchased in accordance with the applicable provisions hereof, whether or not the certificate(s) therefor have been
delivered as required by this Agreement.

 

(g)              
Assignment of Right of First Refusal. The Board of Directors may freely assign the Company’s Right of First
Refusal, in whole or in part. Any person who accepts an assignment of the Right of First Refusal from the Company shall assume
all of the Company’s rights and obligations under this Section 3.

 

SECTION 4.
Other Restrictions On Transfer.

 

(a)               
Transferee Representations. In connection with the issuance and acquisition of Shares under this Agreement, the Transferee
hereby represents and warrants to the Company as follows:

 

                                                                               
(i)          The
Transferee is acquiring and will hold the Transferred Shares for investment for his or her account only and not with a view to,
or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act.

 

    	4

    	 

    

 

                                                                             
(ii)          The
Transferee understands that the Transferred Shares have not been registered under the Securities Act by reason of a specific exemption
therefrom and that the Transferred Shares must be held indefinitely, unless their sale or other transfer is subsequently registered
under the Securities Act or the Transferee obtains an opinion of counsel, in form and substance satisfactory to the Company and
its counsel, that such registration is not required. The Transferee further acknowledges and understands that the Company is under
no obligation to register the Transferred Shares.

 

                                                                           
(iii)          The
Transferee is aware of Rule 144 under the Securities Act, which permits limited public resales of securities acquired in a
non-public offering, subject to the satisfaction of certain conditions. These conditions may include (without limitation) that
certain current public information about the issuer be available, that the resale occur only after a holding period required by
Rule 144 has been satisfied, that the sale occur through an unsolicited “broker’s transaction,” and that
the amount of securities being sold during any three-month period not exceed specified limitations. The Transferee acknowledges
and understands that the conditions for resale set forth in Rule 144 have not been satisfied as of the Date of Transfer and
that the Company is not required to take action to satisfy any such conditions.

 

                                                                           
(iv)          The
Transferee will not sell, transfer or otherwise dispose of the Transferred Shares in violation of the Securities Act, the Exchange
Act, or the rules promulgated thereunder, including Rule 144 under the Securities Act. The Transferee agrees that he or she
will not dispose of the Transferred Shares unless and until he or she has complied with all requirements of this Agreement applicable
to the disposition of Transferred Shares and he or she has provided the Company with written assurances, in substance and form
satisfactory to the Company, that (A) the proposed disposition does not require registration of the Transferred Shares under
the Securities Act or all appropriate action necessary for compliance with the registration requirements of the Securities Act
or with any exemption from registration available under the Securities Act (including Rule 144) has been taken and (B) the
proposed disposition will not result in the contravention of any transfer restrictions applicable to the Transferred Shares under
applicable state law.

 

                                                                             
(v)          The
Transferee has received and has had access to such information as he or she considers necessary or appropriate for deciding whether
to invest in the Transferred Shares, and the Transferee has had an opportunity to ask questions and receive answers from the Company
regarding the terms and conditions of the issuance of the Transferred Shares.

(b)              
Securities Law Restrictions. Regardless of whether the offer and sale of Shares under the Plan have been registered
under the Securities Act or have been registered or qualified under the securities laws of any State or other relevant jurisdiction,
the Company at its discretion may impose restrictions upon the sale, pledge or other transfer of the Transferred Shares (including
the placement of appropriate legends on the stock certificates (or electronic equivalent) or the imposition of stop-transfer instructions)
and may refuse to transfer Shares acquired hereunder (or Shares proposed to be transferred in a subsequent transfer) if, in the
judgment of the Company, such restrictions, legends or refusal are necessary or appropriate to achieve compliance with the Securities
Act or other relevant securities or other laws, including without limitation under Regulation S of the Securities Act or pursuant
to another available exemption from registration.

 

(c)               
Market Stand-Off. In connection with any underwritten public offering by the Company of its equity securities pursuant
to an effective registration statement filed under the Securities Act, including the Company’s initial public offering, the
Transferee or a Subsequent Transferee shall not directly or indirectly sell, make any short sale of, loan, hypothecate, pledge,
offer, grant or sell any option or other contract for the purchase of, purchase any option or other contract for the sale of, or
otherwise dispose of or transfer, or agree to engage in any of the foregoing transactions with respect to, any Transferred Shares
without the prior written consent of the Company or its managing underwriter. Such restriction (the “Market Stand-Off”)
shall be in effect for such period of time following the date of the final prospectus for the offering as may be requested by the
Company or such underwriter. In no event, however, shall such period exceed 180 days plus such
additional period as may reasonably be requested by the Company or such underwriter to accommodate regulatory restrictions on (i) the
publication or other distribution of research reports or (ii) analyst recommendations and opinions, including (without limitation)
the restrictions set forth in Rule 2711(f)(4) of the National Association of Securities Dealers and Rule 472(f)(4) of
the New York Stock Exchange, as amended, or any similar successor rules. The Market Stand-Off shall in any event terminate
two years after the date of the Company’s initial public offering. In the event of the declaration of a stock dividend, a
spin-off, a stock split, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s
outstanding securities without receipt of consideration, any new, substituted or additional securities which are by reason of such
transaction distributed with respect to any Shares subject to the Market Stand-Off, or into which such Shares thereby become convertible,
shall immediately be subject to the Market Stand-Off. In order to enforce the Market Stand-Off, the Company may impose stop-transfer
instructions with respect to the Transferred Shares until the end of the applicable stand-off period. The Company’s underwriters
shall be beneficiaries of the agreement set forth in this Subsection (c). This Subsection (c) shall not apply to Shares
registered in the public offering under the Securities Act.

 

(d)              
Rights of the Company. The Company shall not be required to (i) transfer on its books any Transferred Shares
that have been sold or transferred in contravention of this Agreement or (ii) treat as the owner of Transferred Shares, or
otherwise to accord voting, dividend or liquidation rights to, any Subsequent Transferee to whom Transferred Shares have been transferred
in contravention of this Agreement.

SECTION 5.
Successors And Assigns.

 

Except as otherwise expressly
provided to the contrary, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Company and
its successors and assigns and be binding upon the Transferee and the Transferee’s legal representatives, heirs, legatees,
distributees, assigns and transferees by operation of law, whether or not any such person has become a party to this Agreement
or has agreed in writing to join herein and to be bound by the terms, conditions and restrictions hereof.

 

SECTION 6.
No Retention Rights.

 

Nothing in this Agreement
or in the Plan shall confer upon the Transferee any right to continue providing services to the Company for any period of specific
duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or
retaining the Transferee) or of the Transferee, which rights are hereby expressly reserved by each, to terminate his or her Service
at any time and for any reason, with or without cause.

 

SECTION 7.
 Tax Election.

 

The acquisition of the
Transferred Shares may result in adverse tax consequences that may be avoided or mitigated by filing an election under Code Section 83(b).
Such election may be filed only within 30 days after the date of transfer set forth in the Summary of Stock Grant. The form for
making the Code Section 83(b) election is attached to this Agreement as an Exhibit. The Transferee should consult with
his or her tax advisor to determine the tax consequences of acquiring the Transferred Shares and the advantages and disadvantages
of filing the Code Section 83(b) election. The Transferee acknowledges that it is his or her sole responsibility, and not
the Company’s, to file a timely election under Code Section 83(b), even if the Transferee requests the Company or its
representatives to make this filing on his or her behalf.

 

SECTION 8.
Legends.

 

All certificates evidencing
Transferred Shares shall bear the following legends:

 

“THE SHARES REPRESENTED HEREBY
MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, ENCUMBERED OR IN ANY MANNER DISPOSED OF, EXCEPT IN COMPLIANCE WITH THE TERMS OF A WRITTEN
AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER OF THE SHARES (OR THE PREDECESSOR IN INTEREST TO THE SHARES). SUCH AGREEMENT
GRANTS TO THE COMPANY CERTAIN RIGHTS OF FIRST REFUSAL UPON AN ATTEMPTED TRANSFER OF THE SHARES AND IMPOSES CERTAIN FORFEITURE CONDITIONS
UPON TERMINATION OF SERVICE WITH THE COMPANY. IN ADDITION, THE SHARES ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR A LIMITED PERIOD
FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES AND MAY NOT BE SOLD OR OTHERWISE
DISPOSED OF BY THE HOLDER WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. THE SECRETARY OF THE COMPANY WILL UPON
WRITTEN REQUEST FURNISH A COPY OF SUCH AGREEMENT TO THE HOLDER HEREOF WITHOUT CHARGE.”

 

    	7

    	 

    

 

All certificates evidencing the Transferred
Shares acquired under this Agreement in an unregistered transaction shall bear the following legend (and such other restrictive
legends as are required or deemed advisable under the provisions of any applicable law):

 

“THE SHARES REPRESENTED HEREBY
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”) OR ANY SECURITIES LAWS OF ANY U.S.
STATE, AND MAY NOT BE SOLD, REOFFERED, PLEDGED, ASSIGNED, ENCUMBERED OR OTHERWISE TRANSFERRED OR DISPOSED WITHOUT AN EFFECTIVE
REGISTRATION THEREOF UNDER SUCH ACT OR AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION
IS NOT REQUIRED. IN THE ABSENCE OF REGISTRATION OR THE AVAILABILITY (CONFIRMED BY OPINION OF COUNSEL) OF AN ALTERNATIVE EXEMPTION
FROM REGISTRATION UNDER THE ACT, THESE SHARES MAY NOT BE SOLD, REOFFERED, PLEDGED, ASSIGNED, ENCUMBERED OR OTHERWISE TRANSFERRED
OR DISPOSED OF EXCEPT IN ACCORDANCE WITH REGULATION S (RULES 901 THROUGH 905 AND PRELIMINARY NOTES) OF THE ACT. HEDGING TRANSACTIONS
INVOLVING THESE SHARES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE ACT.”

 

If required by the authorities of any State
in connection with the issuance of the Transferred Shares, the legend or legends required by such State authorities shall also
be endorsed on all such certificates.

SECTION
10. acknowledgements of the Transferee.

 

In addition to the other
terms, conditions and restrictions imposed on the Shares acquired pursuant to this Agreement, the Transferee expressly acknowledges
being subject to Sections 2 (Forfeiture Condition), 3 (Right of First Refusal) and 4 (Other Restrictions on Transfer, including
without limitation the Market Stand-Off), as well as the following provisions:

be deemed to have waived any rights the Transferee might otherwise have had under Section 220 of the Delaware General Corporation
Law to inspect for any proper purpose and to make copies and extracts from the Company’s stock ledger, a list of its stockholders
and its other books and records or the books and records of any subsidiary.  This waiver applies only in the Transferee’s
capacity as a stockholder and does not affect any other inspection rights the Transferee may have under other law or pursuant to
a written agreement with the Company. 

 

(b)              
Plan Discretionary. The Transferee understands and acknowledges that (i) the Plan is entirely discretionary,
(ii) the Company and the Transferee’s employer have reserved the right to amend, suspend or terminate the Plan
at any time, (iii) the transfer of the Transferred Shares does not in any way create any contractual or other right to receive
additional awards under the Plan at any time or in any amount and (iv) all determinations with respect to any additional awards,
including (without limitation) the times when awards will be granted, the number of Shares offered and the vesting schedule, will
be at the sole discretion of the Company.

 

(c)               
Termination of Service. The Transferee understands and acknowledges that participation in the Plan ceases upon termination
of his or her Service for any reason, except as may explicitly be provided otherwise in the Plan or this Agreement.

 

(d)              
Extraordinary Compensation. The value of the Transferred Shares shall be an extraordinary item of compensation outside
the scope of the Transferee’s employment contract, if any, and shall not be considered a part of his or her normal or expected
compensation for purposes of calculating severance, resignation, redundancy or end-of-service payments, bonuses, long-service awards,
pension or retirement benefits or similar payments.

 

(e)               
Authorization to Disclose. The Transferee hereby authorizes and directs the Transferee’s employer to disclose
to the Company or any Subsidiary any information regarding the Transferee’s employment, the nature and amount of the Transferee’s
compensation and the fact and conditions of the Transferee’s participation in the Plan, as the Transferee’s employer
deems necessary or appropriate to facilitate the administration of the Plan.

(f)

transfer Data among themselves as necessary for the purpose of implementation, administration and management of the Transferee’s
participation in the Plan and that the Company and/or any Subsidiary may each further transfer Data to any third party assisting
the Company in the implementation, administration and management of the Plan. The Transferee understands and acknowledges that
the recipients of Data may be located in the United States or elsewhere. The Transferee authorizes such recipients to receive,
possess, use, retain and transfer Data, in electronic or other form, for the purpose of administering the Transferee’s participation
in the Plan, including a transfer to any broker or other third party with whom the Transferee elects to deposit Shares acquired
under the Plan of such Data as may be required for the administration of the Plan and/or the subsequent holding of Shares on the
