NOVAVAX, INC.

2015 Stock Incentive Plan

 

Incentive Stock Option Agreement

 

1.           Grant
of Option. Novavax, Inc., a Delaware corporation (the “Company”), hereby grants to [•]
(the “Optionee”), as of [•] (the “Date
of Grant”), an option (the “Option”), pursuant to the Company’s 2015 Stock Incentive Plan, as
amended from time to time (the “Plan”), to purchase an aggregate of [•]
shares of Common Stock (“Shares”) of the Company at a price of $[•]
per share, purchasable as set forth in, and subject to the terms and conditions of, this Incentive Stock Option Agreement (this
“Agreement”) and the Plan. The Option evidenced by this Agreement is intended to be an incentive stock option
under Section 422 of the Code and is granted to the Optionee in connection with the Optionee’s Service to the Company or
Affiliate.

 

2.           Meaning
of Certain Terms. Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan.
The following terms have the following meanings:

 

(a)          “Affiliate”
means a subsidiary of the Company that would be described in the first sentence of Treas. Regs. § 1.409A-1(b)(5)(iii)(E)(1).

 

(b)          “Beneficiary”
means, in the event of the Optionee’s death, the beneficiary named in the written designation (in form acceptable to the
Administrator) most recently filed with the Administrator by the Optionee prior to the Optionee’s death and not subsequently
revoked, or, if there is no such designated beneficiary, the executor or administrator of the Optionee’s estate. An effective
beneficiary designation will be treated as having been revoked only upon receipt by the Administrator, prior to the Optionee’s
death, of an instrument of revocation in form acceptable to the Administrator.

 

(c)          “Option
Holder” means the Optionee or, if as of the relevant time the Option has passed to a Beneficiary, the Beneficiary.

 

(d)          “Service”
means the Optionee’s employment or other service relationship with the Company and its Affiliates. Service will be deemed
to continue, unless the Administrator expressly provides otherwise, so long as the Optionee is employed by, or otherwise providing
services in a capacity described in Section 3(a) of the Plan to, the Company or an Affiliate. If an Optionee’s employment
or other service relationship is with an Affiliate and that entity ceases to be an Affiliate, the Optionee’s Service will
be deemed to have terminated when the entity ceases to be an Affiliate unless the Optionee transfers Service to the Company or
its remaining Affiliates.

 

     

     

    

 

3.           Option
Vesting, Exercise and Expiration.

 

(a)          Vesting
Schedule. As used herein with respect to the Option or any portion thereof, the term “vest” means to become exercisable
and the term “vested” as applied to any outstanding portion of the Option means that the Option is then exercisable,
subject in each case to the terms of the Plan. Unless earlier terminated, forfeited, relinquished or expired, the Option will vest
as to the percentage of the Shares set forth in the table below on the respective vesting date set forth in the table below (with
the number of Shares that vest on any such date being rounded down to the nearest whole Share and the Option becoming vested as
to 100% of the Shares on the last vesting date), subject to the Optionee’s continuous Service through each such vesting date.

 

	Vesting Date	 	Percentage of Shares as to which

Option is Vested
	[•]	 	[•]

 

(b)          Expiration
Date. The latest date on which the Option or any portion thereof may be exercised will be the 10th anniversary of
the Date of Grant (the “Expiration Date”). Except as provided in Section 5(e) of the Plan, if the Option is
not exercised by the Expiration Date the Option or any remaining portion thereof will thereupon immediately terminate.

 

(c)          Exercise
Procedure. No portion of the Option may be exercised until such portion vests. Each election to exercise any vested portion
of the Option will be subject to the terms and conditions of the Plan and this Agreement and shall be in writing (including in
electronic form), signed by the Option Holder (or in such other form as is acceptable to the Administrator). Each such written
exercise election must be received by the Company at its primary office or by such other party as the Administrator may prescribe
and be accompanied by payment in full as provided in the Plan and Section 3(d) hereof. The Option Holder may purchase less than
the number of Shares covered hereby, provided that no partial exercise of the Option may be for any fractional Share.

 

(d)          Payment
of Exercise Price. The exercise price may be paid by cash or check made to the order of the Company in an amount equal to the
aggregate exercise price of the portion of the Option being exercised or through a broker-assisted exercise program acceptable
to the Administrator or, to the extent legally permissible and acceptable to the Administrator, (i) by delivery to the Company
of shares of Common Stock already owned by the Optionee having a Fair Market Value equal in amount to the aggregate exercise price
of the portion of the Option being exercised, (ii) through the withholding of shares of Common Stock otherwise to be delivered
upon exercise of the Option having a Fair Market Value equal to the aggregate exercise price of the portion of the Option being
exercised, or (iii) by any other means approved by the Administrator. Fractional shares of Common Stock of the Company will not
be accepted in payment of the purchase price of Shares acquired upon exercise of the Option. In the event that the Option is exercised
by a person other than the Optionee, the Company will be under no obligation to deliver Shares hereunder unless and until it is
satisfied as to the authority of the Option Holder to exercise the Option and compliance with applicable securities laws.

 

(e)          Treatment
of the Option upon Cessation of Service. If the Optionee’s Service ceases, the Option, to the extent not already vested,
will be immediately forfeited, and any vested portion of the Option that is then outstanding will be treated as follows:

 

    	 	-2-	 

     

    

 

(i)          Subject
to clauses (ii) and (iii) below and Section 4 of this Agreement, the Option, to the extent vested immediately prior to the cessation
of the Optionee’s Service, will remain exercisable until the earlier of (A) the date that is three months following the date
of such cessation of Service, or (B) the Expiration Date, and except to the extent previously exercised as permitted by this Section
3(e)(i) will thereupon immediately terminate.

 

(ii)         Subject
to clause (iii) below and Section 4 of this Agreement, the Option, to the extent vested immediately prior to (A) the cessation
of the Optionee’s Service due to death or disability (within the meaning of Section 22(e)(3) of the Code or any successor
provision thereto), or (B) the Optionee’s death within three months following the Optionee’s termination of Service,
will remain exercisable until the earlier of (x) the first anniversary of the date of the Optionee’s death or of the date
of the termination of the Optionee’s Service due to disability, as applicable, or (y) the Expiration Date, and except to
the extent previously exercised as permitted by this Section 3(e)(ii) will thereupon immediately terminate.

 

(iii)        If
the Optionee’s Service is terminated by the Company and its subsidiaries in connection with an act or failure to act constituting
Cause (as the Administrator, in its sole discretion, may determine), the Option (whether or not vested) will immediately terminate
and be forfeited upon such termination.

 

Upon a cessation of the Optionee’s
employment with the Company and its subsidiaries that is not a cessation of Service, the Option will cease to be an incentive stock
option and will become a Non-Statutory Option if the Option, to the extent exercisable, is not exercised within the periods set
forth in the Treasury Regulations applicable to incentive stock options.

 

4.           Forfeiture;
Recovery of Compensation.

 

(a)          The
Administrator may cancel, rescind, withhold or otherwise limit or restrict the Option at any time if the Optionee is not in compliance
with all applicable provisions of this Agreement and the Plan.

 

(b)          By
accepting the Option, the Optionee expressly acknowledges and agrees that his or her rights, and those of any permitted transferee
of the Option, under the Option, including to any Common Stock acquired under the Option or proceeds from the disposition thereof,
are subject to Section 8(e) of the Plan (including any successor provision). Nothing in the preceding sentence shall be construed
as limiting the general application of Section 9 of this Agreement.

 

5.           Transfer
of Option. The Option may not be transferred except as expressly permitted under Section 8(b) of the Plan.

 

    	 	-3-	 

     

    

 

6.           Taxes.

 

(a)          Withholding.
If at the time the Option is exercised the Company determines that under applicable law and regulations it could be liable for
the withholding of any federal, state or local tax upon such exercise or with respect to a disposition of any Common Stock acquired
upon such exercise, the Optionee by signing this Agreement (and any other Option Holder by exercising all or any part of the Option)
expressly acknowledges and agrees that the Option Holder’s rights hereunder, including the right to be issued Shares upon
exercise, are subject to the Option Holder promptly paying to the Company in cash (or by such other means as may be acceptable
to the Administrator in its discretion) all taxes required to be withheld. No Shares will be transferred pursuant to the exercise
of the Option unless and until the person exercising the Option has remitted to the Company an amount in cash sufficient to satisfy
any federal, state, or local withholding tax requirements, or has made other arrangements satisfactory to the Company with respect
to such taxes. The Optionee by signing this Agreement (and any other Option Holder by exercising all or any part of the Option)
authorizes the Company and its subsidiaries to withhold such amount from any amounts otherwise owed to the Option Holder, but nothing
in this sentence shall be construed as relieving the Option Holder of any liability for satisfying his or her obligation under
the preceding provisions of this Section.

 

(b)          Disqualifying
Disposition. If the Optionee disposes of the Shares acquired upon exercise of the Option within two years from the Date of
Grant or one year after such Shares were acquired pursuant to the exercise of the Option, the Optionee shall notify the Company
in writing of such disposition within 15 days of such disposition.

 

(c)          Annual
Limit for Incentive Stock Options. To the extent that the aggregate fair market value (determined at the time of grant) of
the shares of Stock subject to the Option and all other incentive stock options the Optionee holds that are exercisable for the
first time during any calendar year (under all plans of the Company and its related corporations) exceeds $100,000, the options
held by the Optionee or portions thereof that exceed such limit (according to the order in which they were granted in accordance
with the regulations under Section 422 of the Code) shall be treated as Non-Statutory Options.

 

(d)          Limitation
on Liability. The Optionee acknowledges and agrees that the Company or the Administrator may take any action permitted under
the Plan without regard to the effect such action may have on the status of the Option as an incentive stock option under Section
422 of the Code and that such actions may cause the Option to fail to be treated as an incentive stock option under Section 422
of the Code. The Optionee further acknowledges and agrees that neither the Company, nor any of its affiliates, nor the Administrator,
nor any person acting on behalf of the Company, any of its affiliates, or the Administrator, will be liable to the Optionee or
to the estate or beneficiary of the Optionee or to any other person by reason of the failure of the Option to satisfy the requirements
of Section 422 of the Code.

 

7.           Effect
on Service. Neither the grant of the Option, nor the issuance of Shares upon exercise of the Option, will give the Optionee
any right to be retained in the employ or service of the Company or any of its affiliates, affect the right of the Company or
any of its affiliates to discharge or discipline such Optionee at any time, or affect any right of such Optionee to terminate
his or her employment or service at any time.

 

8.           Rights
as a Stockholder. The Option Holder shall have no rights as a stockholder with respect to any Shares that may be purchased
by exercise of the Option (including, without limitation, any rights to receive dividends or non-cash distributions with respect
to such Shares) except as to shares of Common Stock actually issued under the Plan. No adjustment shall be made for dividends
or other rights for which the record date is prior to the date such shares of Common Stock are issued.

 

    	 	-4-	 

     

    

 

9.           Provisions
of the Plan. This Agreement is subject in its entirety to the provisions of the Plan, which are incorporated herein by reference.
A copy of the Plan as in effect on the Date of Grant has been furnished to the Optionee. By exercising all or any part of the Option,
the Option Holder agrees to be bound by the terms of the Plan and this Agreement. In the event of any conflict between the terms
of this Agreement and the Plan, the terms of the Plan shall control.

 

10.           Acknowledgements.
The Optionee acknowledges and agrees that (i) this Agreement may be executed in two or more counterparts, each of which shall be
an original and all of which together shall constitute one and the same instrument and (ii) this agreement may be executed and
exchanged using facsimile, portable document format (PDF) or electronic signature, which, in each case, shall constitute an original
signature for all purposes hereunder.

NOVAVAX, INC.

2015 Stock Incentive Plan

 

Restricted Stock Agreement

 

This
Restricted Stock Agreement (“Agreement”) is made as of [•]
by and between Novavax, Inc., a Delaware corporation (“Company”),
and [•] (“Stockholder”).

 

Whereas,
the Company desires to issue, and Stockholder desires to acquire, stock of the Company as herein described, on the terms and conditions
hereinafter set forth;

 

Whereas,
the issuance of common stock hereby is pursuant to Section 7(a) of the Company’s 2015 Stock Incentive Plan (“Plan”),
which is a compensatory benefit arrangement for the employees, officers, directors, consultants and advisors of the Company.

 

Now,
Therefore, It Is Agreed between the parties as follows:

 

1.          Issuance
of Stock. The Company hereby agrees to issue to Stockholder, and Stockholder agrees to accept, an aggregate of [•]
shares of the Common Stock of the Company (the “Stock”), having a value as determined by the Board of
Directors of the Company of $[•] per share (for an aggregate
value of $[•]), in exchange for Stockholder’s past services
and/or expected provision of future services on behalf of the Company or its affiliated entities.

 

2.          Risk
of Forfeiture

 

(a)          Subject
to Section 2(c), and with respect to Stock that has vested pursuant to Section 2(b), if Stockholder ceases to be an employee, director
or consultant of the Company or its subsidiaries for any reason, including but not limited to death or disability, all then-outstanding
and unvested Stock acquired by Stockholder hereunder shall be automatically and immediately forfeited. Stockholder, or Stockholder’s
personal representative as the case may be, hereby (i) appoints the Company as the attorney-in-fact of the undersigned to take
such actions as may be necessary or appropriate to effectuate a transfer of the record ownership, at no cost to the Company, of
any such shares that are unvested and forfeited hereunder, (ii) agrees to deliver to the Company, as a precondition to the issuance
of any certificate(s) of Stock, one or more stock powers, endorsed in blank, with respect to such Stock, and (iii) agrees to take
such other actions as the Company may reasonably request to accomplish the transfer or forfeiture of any such Stock hereunder.

 

(b)          On
the date that is [•] after the “Vesting Commencement Date” (as set forth on the signature page to
this Agreement), [•]. In order for the Stock to vest on a particular vesting installment date, the Stockholder must have been
and must be an employee, director or consultant of the Company or a parent or subsidiary of the Company continuously until such
vesting installment date. By way of example, if an employee terminates and immediately thereafter becomes a consultant of the company,
such individual will be deemed to have a continuous qualifying role with the Company. Accordingly, all of the Stock shall vest
as of the [•] anniversary of the Vesting Commencement Date.
The final vesting installment may cover additional shares to take into account any fractional shares.

 

     

     

    

  

3.          Adjustments
to Stock. If, from time to time, prior to full vesting, there is any change
affecting the Company’s outstanding Common Stock as a class that is effected without the receipt of consideration by the
Company (through merger, consolidation, reorganization, reincorporation, stock dividend, dividend in property other than cash,
stock split, liquidating dividend, combination of shares, change in corporation structure or other transaction not involving the
receipt of consideration by the Company), then any and all new, substituted or additional securities or other property to which
Stockholder is entitled by reason of Stockholder’s ownership of Stock shall be immediately subject to vesting hereunder and
be included in the word “Stock” for all purposes of this Agreement with the same force and effect as
the shares of the Stock presently subject to vesting.

 

4.          Escrow
of Unvested Stock. As security for Stockholder’s faithful performance of the terms of this Agreement and to insure
the availability for delivery of Stockholder’s Stock, Stockholder agrees, at the closing hereunder, to deliver to and deposit
with the Secretary of the Company or the Secretary’s designee (“Escrow Agent”), as Escrow Agent
in this transaction, three (3) stock assignments duly endorsed (with date and number of shares blank) in a form attached hereto
as Exhibit A, together with a certificate or certificates evidencing all of the Stock subject to vesting; said documents are
to be held by the Escrow Agent and delivered by said Escrow Agent pursuant to the Joint Escrow Instructions of the Company and
Stockholder set forth in Exhibit B attached hereto and incorporated by this reference, which instructions shall also be delivered
to the Escrow Agent at the closing hereunder. Stockholder hereby acknowledges that the Secretary of the Company, or the Secretary’s
designee, is so appointed as the Escrow Agent. Stockholder agrees that the Escrow Agent shall not be liable to any party hereof
(or to any other party), and may rely upon any letter, notice or other document executed by any signature purported to be genuine
and may resign at any time. Stockholder agrees that if the Secretary of the Company, or the Secretary’s designee, resigns
as Escrow Agent for any or no reason, the Board of Directors of the Company shall have the power to appoint a successor to serve
as Escrow Agent pursuant to the terms of this Agreement. Stockholder agrees that if the Secretary of the Company resigns as Secretary,
the successor Secretary shall serve as Escrow Agent pursuant to the terms of this Agreement.

 

5.          Rights
of Stockholder. Subject to the provisions of Sections 6, 8, 12 and 13 herein, Stockholder shall exercise all rights
and privileges of a shareholder of the Company with respect to the Stock deposited in escrow. Stockholder shall be deemed to be
the holder for purposes of receiving any dividends that may be paid with respect to such shares of Stock and for the purpose of
exercising any voting rights relating to such shares of Stock, even if some or all of such shares of Stock have not yet vested.

 

6.          Limitations
on Transfer. In addition to any other limitation on transfer created by applicable securities laws, Stockholder shall
not assign, hypothecate, donate, encumber or otherwise dispose of any interest in the Stock while the Stock is not fully vested.
After any Stock has been fully vested, Stockholder shall not assign, hypothecate, donate, encumber or otherwise dispose of any
interest in the Stock except in compliance with the provisions herein and applicable securities laws. During the period of time
during which the Stockholder holds the Common Stock, the value of the Common Stock may increase or decrease, and any risk associated
with such Common Stock and such fluctuation in value shall be borne by the Stockholder.

 

    	 	2.	 

     

    

 

7.          Restrictive
Legends. All certificates representing the Stock shall have endorsed thereon legends in substantially the following
forms (in addition to any other legend which may be required by other agreements between the parties hereto):

 

(a)          “THE
SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AN OPTION SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED
HOLDER, OR SUCH HOLDER’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY. ANY
TRANSFER OR ATTEMPTED TRANSFER OF ANY SHARES SUBJECT TO SUCH OPTION IS VOID WITHOUT THE PRIOR EXPRESS WRITTEN CONSENT OF THE COMPANY.”

 

(b)          Any
legend required by Company officials.

 

8.          Investment
Representations. In connection with the issuance of the Stock, Stockholder represents to the Company the following:

 

(a)          Stockholder
is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company
to reach an informed and knowledgeable decision to acquire the Stock. Stockholder is acquiring the Stock for investment for Stockholder’s
own account only and not with a view to, or for resale in connection with, any “distribution” thereof
within the meaning of the Act.

 

Stockholder is familiar
with the provisions of Rule 144, under the Securities Act of 1933, as in effect from time to time, which, in substance, permit
limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer thereof
(or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. The Stock may
be resold by Stockholder in certain limited circumstances subject to the provisions of Rule 144, which requires, among other things:
(i) the availability of certain public information about the Company and (ii) the resale occurring following the required holding
period under Rule 144 after the Stockholder has acquired, and made full payment of (within the meaning of Rule 144), the securities
to be sold.

 

(b)          Stockholder
further understands that at the time Stockholder wishes to sell the Stock there may be no public market upon which to make such
a sale, and that, even if such a public market then exists, the Company may not be satisfying the current public information requirements
of Rule 144, and that, in such event, Stockholder would be precluded from selling the Stock under Rule 144 even if the minimum
holding period requirement had been satisfied.

 

    	 	3.	 

     

    

 

9.          Section
83(b) Election. Stockholder understands that Section 83(a) of the Code, taxes as ordinary income the difference between
the amount paid for the Stock and the fair market value of the Stock as of the date any restrictions on the Stock lapse. In this
context, “restriction” includes the right of the Company to receive transfer of the Stock as set forth
in Section 2 above. Stockholder understands that Stockholder may elect to be taxed at the time the Stock is acquired, rather than
when and as vesting occurs, by filing an election under Section 83(b) (an “83(b) Election”) of the Code
with the Internal Revenue Service within thirty (30) days from the date of transfer. Even if the fair market value of the Stock
at the time of the execution of this Agreement equals the amount paid for the Stock, the 83(b) Election must be made to avoid income
under Section 83(a) in the future. Stockholder understands that failure to file such an 83(b) Election in a timely manner may result
in adverse tax consequences for Stockholder. Stockholder further understands that an additional copy of such 83(b) Election is
required to be filed with his or her federal income tax return for the calendar year in which the date of this Agreement falls.
Stockholder further acknowledges and understands that it is Stockholder’s sole obligation and responsibility to timely
file such 83(b) Election, and neither the Company nor the Company’s legal or financial advisors shall have any obligation
or responsibility with respect to such filing. Stockholder acknowledges that the foregoing is only a summary of the effect
of United States federal income taxation with respect to acquisition of the Stock hereunder, and does not purport to be complete.
Stockholder further acknowledges that the Company has directed Stockholder to seek independent advice regarding the applicable
provisions of the Code, the income tax laws of any municipality, state or foreign country in which Stockholder may reside, and
the tax consequences of Stockholder’s death. Stockholder assumes all responsibility for filing an 83(b) Election and paying
all taxes resulting from such election or the lapse of the restrictions on the Stock.

 

10.         Refusal
to Transfer. The Company shall not be required (a) to transfer on its books any shares of Stock of the Company which
shall have been transferred in violation of any of the provisions set forth in this Agreement, or (b) to treat as owner of such
shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such shares shall have been so
transferred.

 

11.         No
Service Rights. This Agreement is not an employment or service contract and nothing in this Agreement shall affect in
any manner whatsoever the right or power of the Company (or a parent or subsidiary of the Company) to terminate Stockholder’s
employment or service for any reason at any time, with or without cause and with or without notice.

 

12.         Miscellaneous.

 

(a)          Notices.
All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (i) upon personal delivery
to the party to be notified, (ii) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient,
and if not during normal business hours of the recipient, then on the next business day, (iii) five (5) calendar days after
having been sent by registered or certified mail, return receipt requested, postage prepaid, or (iv) one (1) business day
after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.
All communications shall be sent to the other party hereto at such party’s address hereinafter set forth on the signature
page hereof, or at such other address as such party may designate by ten (10) days advance written notice to the other party hereto.

 

(b)          Successors
and Assigns. This Agreement shall inure to the benefit of the successors and assigns of the Company and, subject to the restrictions
on transfer herein set forth, be binding upon Stockholder, Stockholder’s successors, and assigns. Company’s rights
hereunder shall be assignable by the Company at any time or from time to time, in whole or in part.

 

    	 	4.	 

     

    

 

(c)          Attorneys’
Fees; Specific Performance. Stockholder shall reimburse the Company for all costs incurred by the Company in enforcing the
performance of, or protecting its rights under, any part of this Agreement, including reasonable costs of investigation and attorneys’
fees. It is the intention of the parties that, upon a forfeiture pursuant to the terms of this Agreement, the Company shall be
entitled to receive the Stock, in specie, in order to have such Stock available for future issuance without dilution of the holdings
of other shareholders. Furthermore, it is expressly agreed between the parties that money damages are inadequate to compensate
the Company for the Stock and that the Company shall be entitled to specific enforcement of its rights to purchase and receive
said Stock.

 

(d)          Governing
Law; Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware. The parties
agree that any action brought by either party to interpret or enforce any provision of this Agreement shall be brought in, and
each party agrees to, and does hereby, submit to the jurisdiction and venue of, the appropriate state or federal court for the
district encompassing the Company’s principal place of business.

 

(e)          Further
Execution. The parties agree to take all such further action(s) as may reasonably be necessary to carry out and consummate
this Agreement as soon as practicable, and to take whatever steps may be necessary to obtain any governmental approval in connection
with or otherwise qualify the issuance of the securities that are the subject of this Agreement.

 

(f)          Independent
Counsel. Stockholder acknowledges that Stockholder has been provided with an opportunity to consult with their own legal counsel
and tax or other advisors with respect to this Agreement.

 

(g)          Entire
Agreement; Amendment. This Agreement and the Plan constitute the entire agreement between the parties with respect to the subject
matter hereof and supersede and merge all prior agreements or understandings, whether written or oral. This Agreement may not be
amended, modified or revoked, in whole or in part, except by an agreement in writing signed by each of the parties hereto. The
provisions of the Plan apply to the Stock awarded under this Agreement, and any word or term that is capitalized, but not otherwise
defined in this Agreement, shall have the meaning set forth in the Plan.

 

(h)          Severability.
If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate
such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such
provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted
as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.

 

(i)          Counterparts.
This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together
shall constitute one instrument.

 

    	 	5.	 

     

    

 

In
Witness Whereof, the parties hereto have executed this Agreement as of the day and year first above written.

Stockholder
acknowledges and agrees that the vesting of shares pursuant to Section 2 hereof is earned only by continuing service as an
employee, consultant or director at the will of the company. Stockholder further acknowledges and agrees that nothing in this agreement
shall confer upon Stockholder any right with respect to continuation of such employment or service relationship with the company,
