and its Affiliates upon whose judgment, initiative and efforts the Company largely depends for the successful conduct of its business
to acquire a proprietary interest in the Company. It is anticipated that providing such persons with a direct stake in the Company’s

(b)          Powers
of Administrator. The Administrator shall have the power and authority to grant Awards consistent with the terms of the Plan,
including the power and authority:


 


(i)          to
select the individuals to whom Awards may from time to time be granted;


 


(ii)         to

Rights, Restricted Stock Awards, Restricted Stock Units, Unrestricted Stock Awards, Cash-Based Awards, and Dividend Equivalent
Rights, or any combination of the foregoing, granted to any one or more grantees;

determine the number of shares of Stock to be covered by any Award;


 


(iv)        to
determine and modify from time to time the terms and conditions, including restrictions, not inconsistent with the terms of the
Plan, of any Award, which terms and conditions may differ among individual Awards and grantees, and to approve the forms of Award
Certificates;


 


(v)         to
accelerate at any time the exercisability or vesting of all or any portion of any Award;


 


(vi)        subject
to the provisions of Section 5(c) or Section 6(d), as applicable, to extend at any time the period in which Stock
Options and Stock Appreciation Rights may be exercised; and


 


(vii)       at
any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and
proceedings as it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written
instruments); to make all determinations it deems advisable for the administration of the Plan; to decide all disputes arising
in connection with the Plan; and to otherwise supervise the administration of the Plan.


 


All decisions and interpretations of the
Administrator shall be binding on all persons, including the Company and Plan grantees.


 


(c)          Delegation
of Authority to Grant Awards. Subject to applicable law, the Administrator, in its discretion, may delegate to a committee
consisting of one or more officers of the Company, including the Chief Executive Officer of the Company, all or part of the Administrator’s
authority and duties with respect to the granting of Awards to individuals who are (i) not subject to the reporting and other
provisions of Section 16 of the Exchange Act and (ii) not members of the delegated committee. Any such delegation by
the Administrator shall include a limitation as to the amount of Stock underlying Awards that may be granted during the period
of the delegation and shall contain guidelines as to the determination of the exercise price and the vesting criteria. The Administrator
may revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Administrator’s
delegate or delegates that were consistent with the terms of the Plan.


 






    	 	4	 



     


    

 


(d)          Award
Certificate. Awards under the Plan shall be evidenced by Award Certificates that set forth the terms, conditions and limitations
for each Award which may include, without limitation, the term of an Award and the provisions applicable in the event employment
or service terminates.


 


(e)          Indemnification.
Neither the Board nor the Administrator, nor any member of either or any delegate thereof, shall be liable for any act, omission,
interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and
the Administrator (and any delegate thereof) shall be entitled in all cases to indemnification and reimbursement by the Company
in respect of any claim, loss, damage or expense (including, without limitation, reasonable attorneys’ fees) arising or resulting
therefrom to the fullest extent permitted by law and/or under the Company’s articles or bylaws or any directors’ and
officers’ liability insurance coverage which may be in effect from time to time and/or any indemnification agreement between
such individual and the Company.


 


(f)           Foreign
Award Recipients. Notwithstanding any provision of the Plan to the contrary, in order to comply with the laws in other countries
in which the Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Administrator,
in its sole discretion, shall have the power and authority to: (i) determine which Subsidiaries shall be covered by the Plan;
(ii) determine which individuals outside the United States are eligible to participate in the Plan; (iii) modify the
terms and conditions of any Award granted to individuals outside the United States to comply with applicable foreign laws; (iv) establish
subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such actions
to be necessary or advisable (and such subplans and/or modifications shall be attached to this Plan as appendices); provided, however,
that no such subplans and/or modifications shall increase the share limitations contained in Section 3(a) hereof; and
(v) take any action, before or after an Award is made, that the Administrator determines to be necessary or advisable to obtain
approval or comply with any local governmental regulatory exemptions or approvals. Notwithstanding the foregoing, the Administrator
may not take any actions hereunder, and no Awards shall be granted, that would violate the Exchange Act or any other applicable
United States securities law, the Code, or any other applicable United States governing statute or law.


 


SECTION 3. STOCK
ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION


 


(a)          Stock
Issuable. The maximum number of shares of Stock reserved and available for issuance under the Plan shall be 3,000,000 shares
(the “Initial Limit”), subject to adjustment as provided in this Section 3, plus on January 1, 2022 and each
January 1 thereafter, the number of shares of Stock reserved and available for issuance under the Plan shall be cumulatively
increased by (i) 4 percent of the number of shares of Stock issued and outstanding on the immediately preceding December 31
or (ii) such lesser number of shares as determined by the Administrator (the “Annual Increase”). Subject to such
overall limitation, the maximum aggregate number of shares of Stock that may be issued in the form of Incentive Stock Options shall
not exceed the Initial Limit, cumulatively increased on January 1, 2022 and each January 1 thereafter by the lesser of
the Annual Increase for such year or 2,000,000 shares of Stock, subject in all cases to adjustment as provided in Section 3.
For purposes of this limitation, the shares of Stock underlying any awards under the Plan and under the Company’s 2012 Stock
Option and Grant Plan, as amended, that are forfeited, canceled, held back upon exercise of an option or settlement of an award
to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of Stock
or otherwise terminated (other than by exercise) shall be added back to the shares of Stock available for issuance under the Plan
and, to the extent permitted under Section 422 of the Code and the regulations promulgated thereunder, the shares of Stock
that may be issued as Incentive Stock Options. In the event the Company repurchases shares of Stock on the open market, such shares
shall not be added to the shares of Stock available for issuance under the Plan. Subject to such overall limitations, shares of
Stock may be issued up to such maximum number pursuant to any type or types of Award. The shares available for issuance under the
Plan may be authorized but unissued shares of Stock or shares of Stock reacquired by the Company.


 






    	 	5	 



     


    

 


(b)          Changes
in Stock. Subject to Section 3(c) hereof, if, as a result of any reorganization, recapitalization, reclassification,
stock dividend, extraordinary cash dividend, stock split, reverse stock split or other similar change in the Company’s capital
stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or
other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash
assets are distributed with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation,
sale of all or substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged
for securities of the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate
or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, including the maximum
number of shares that may be issued in the form of Incentive Stock Options, (ii) the number and kind of shares or other securities
subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per share subject to each outstanding
Restricted Stock Award, and (iv) the exercise price for each share subject to any then outstanding Stock Options and Stock
Appreciation Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number
of shares subject to Stock Options and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights
remain exercisable. The Administrator shall also make equitable or proportionate adjustments in the number of shares subject to
outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration cash dividends paid other
than in the ordinary course or any other extraordinary corporate event. The adjustment by the Administrator shall be final, binding
and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Administrator
in its discretion may make a cash payment in lieu of fractional shares.


 


(c)          Mergers
and Other Transactions. In the case of and subject to the consummation of a Sale Event, the parties thereto may cause the assumption
or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the
successor entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per
share exercise prices, as such parties shall agree. To the extent the parties to such Sale Event do not provide for the assumption,
continuation or substitution of Awards, upon the effective time of the Sale Event, the Plan and all outstanding Awards granted
hereunder shall terminate. In such case, except as may be otherwise provided in the relevant Award Certificate, all Awards with
time-based vesting, conditions or restrictions shall become fully vested and exercisable or nonforfeitable as of the effective
time of the Sale Event, and all Awards with conditions and restrictions relating to the attainment of performance goals may become
vested and exercisable or nonforfeitable in connection with a Sale Event in the Administrator’s discretion or to the extent
specified in the relevant Award Certificate. In the event of such termination, (i) the Company shall have the option (in its
sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding Options and Stock Appreciation Rights,
in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price multiplied by the
number of shares of Stock subject to outstanding Options and Stock Appreciation Rights (to the extent then exercisable at prices
not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding Options and Stock Appreciation
Rights (provided that, in the case of an Option or Stock Appreciation Right with an exercise price equal to or greater than the
Sale Price, such Option or Stock Appreciation Right shall be cancelled for no consideration); or (ii) each grantee shall be
permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Administrator, to
exercise all outstanding Options and Stock Appreciation Rights (to the extent then exercisable) held by such grantee. The Company
shall also have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding
other Awards in an amount equal to the Sale Price multiplied by the number of vested shares of Stock under such Awards.


 






    	 	6	 



     


    

 


SECTION 4. ELIGIBILITY


 


Grantees under the Plan will be such employees,
Non-Employee Directors and Consultants of the Company and its Affiliates as are selected from time to time by the Administrator
in its sole discretion; provided that Awards may not be granted to employees, Directors or Consultants who are providing services
only to any “parent” of the Company, as such term is defined in Rule 405 of the Act, unless (i) the stock
underlying the Awards is treated as “service recipient stock” under Section 409A or (ii) the Company, in
consultation with its legal counsel, has determined that such Awards are exempt from or otherwise comply with Section 409A.


 


SECTION 5. STOCK
OPTIONS


 


(a)          Award
of Stock Options. The Administrator may grant Stock Options under the Plan. Any Stock Option granted under the Plan shall be
in such form as the Administrator may from time to time approve.


 


Stock Options granted under the Plan may
be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the
Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the
Code. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option.


 


Stock Options granted pursuant to this Section 5
shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent
with the terms of the Plan, as the Administrator shall deem desirable. If the Administrator so determines, Stock Options may be
granted in lieu of cash compensation at the optionee’s election, subject to such terms and conditions as the Administrator
may establish.


 






    	 	7	 



     


    

 


(b)          Exercise
Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 5 shall be
determined by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date
of grant. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the exercise price of such Incentive
Stock Option shall be not less than 110 percent of the Fair Market Value on the grant date. Notwithstanding the foregoing, Stock
Options may be granted with an exercise price per share that is less than 100 percent of the Fair Market Value on the date of grant
(i) pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code, (ii) to
individuals who are not subject to U.S. income tax on the date of grant or (iii) if the Stock Option is otherwise compliant
with Section 409A.


 


(c)          Option
Term. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than
ten years after the date the Stock Option is granted. In the case of an Incentive Stock Option that is granted to a Ten Percent
Owner, the term of such Stock Option shall be no more than five years from the date of grant.


 


(d)          Exercisability;
Rights of a Stockholder. Stock Options shall become exercisable at such time or times, whether or not in installments, as shall
be determined by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability
of all or any portion of any Stock Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the
exercise of a Stock Option and not as to unexercised Stock Options.


 


(e)          Method
of Exercise. Stock Options may be exercised in whole or in part, by giving written or electronic notice of exercise to the
Company, specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following
methods except to the extent otherwise provided in the Award Certificate:


 


(i)          In
cash, by certified or bank check or other instrument acceptable to the Administrator;


 


(ii)         Through
the delivery (or attestation to the ownership following such procedures as the Company may prescribe) of shares of Stock that are
not then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise
date;


 


(iii)        By
the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to
promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in
the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures
and enter into such agreements of indemnity and other agreements as the Company shall prescribe as a condition of such payment
procedure; or


 


(iv)        With
respect to Stock Options that are not Incentive Stock Options, by a “net exercise” arrangement pursuant to which the
Company will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market
Value that does not exceed the aggregate exercise price.


 






    	 	8	 



     


    

 


Payment instruments will be received subject to collection.
The transfer to the optionee on the records of the Company or of the transfer agent of the shares of Stock to be purchased pursuant
to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance
with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other
requirements contained in the Award Certificate or applicable provisions of laws (including the satisfaction of any withholding
taxes that the Company is obligated to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase
price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the optionee
upon the exercise of the Stock Option shall be net of the number of attested shares. In the event that the Company establishes,
for itself or using the services of a third party, an automated system for the exercise of Stock Options, such as a system using
an internet website or interactive voice response, then the paperless exercise of Stock Options may be permitted through the use
of such an automated system.


 


(f)           Annual
Limit on Incentive Stock Options. To the extent required for “incentive stock option” treatment under Section 422
of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which
Incentive Stock Options granted under this Plan and any other plan of the Company or its parent and subsidiary corporations become
exercisable for the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any Stock
Option exceeds this limit, it shall constitute a Non-Qualified Stock Option.


 


SECTION 6. STOCK
APPRECIATION RIGHTS


 


(a)          Award
of Stock Appreciation Rights. The Administrator may grant Stock Appreciation Rights under the Plan. A Stock Appreciation Right
is an Award entitling the recipient to receive shares of Stock (or cash, to the extent explicitly provided for in the applicable
Award Certificate) having a value equal to the excess of the Fair Market Value of a share of Stock on the date of exercise over
the exercise price of the Stock Appreciation Right multiplied by the number of shares of Stock with respect to which the Stock
Appreciation Right shall have been exercised.


 


(b)          Exercise
Price of Stock Appreciation Rights. The exercise price of a Stock Appreciation Right shall not be less than 100 percent of
the Fair Market Value of the Stock on the date of grant. Notwithstanding the foregoing, Stock Appreciation Rights may be granted
with an exercise price per share that is less than 100 percent of the Fair Market Value on the date of grant (i) pursuant
to a transaction described in, and in a manner consistent with, Section 424(a) of the Code, (ii) to individuals
who are not subject to U.S. income tax on the date of grant, or (iii) if the Stock Appreciation Right is otherwise compliant
with Section 409A


 


(c)          Grant
and Exercise of Stock Appreciation Rights. Stock Appreciation Rights may be granted by the Administrator independently of any
Stock Option granted pursuant to Section 5 of the Plan.


 






    	 	9	 



     


    

 


(d)          Terms
and Conditions of Stock Appreciation Rights. Stock Appreciation Rights shall be subject to such terms and conditions as shall
be determined on the date of grant by the Administrator. The term of a Stock Appreciation Right may not exceed ten years. The terms
and conditions of each such Award shall be determined by the Administrator, and such terms and conditions may differ among individual
Awards and grantees.


 


SECTION 7. RESTRICTED
STOCK AWARDS


 


(a)          Nature
of Restricted Stock Awards. The Administrator may grant Restricted Stock Awards under the Plan. A Restricted Stock Award is
any Award of Restricted Shares subject to such restrictions and conditions as the Administrator may determine at the time of grant.
Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance
goals and objectives.


 


(b)          Rights
as a Stockholder. Upon the grant of the Restricted Stock Award and payment of any applicable purchase price, a grantee shall
have the rights of a stockholder with respect to the voting of the Restricted Shares and receipt of dividends; provided that if
the lapse of restrictions with respect to the Restricted Stock Award is tied to the attainment of performance goals, any dividends
paid by the Company during the performance period shall accrue and shall not be paid to the grantee until and to the extent the
performance goals are met with respect to the Restricted Stock Award. Unless the Administrator shall otherwise determine, (i) uncertificated
Restricted Shares shall be accompanied by a notation on the records of the Company or the transfer agent to the effect that they
are subject to forfeiture until such Restricted Shares are vested as provided in Section 7(d) below, and (ii) certificated
Restricted Shares shall remain in the possession of the Company until such Restricted Shares are vested as provided in Section 7(d) below,
and the grantee shall be required, as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator
may prescribe.


 


(c)          Restrictions.
Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically
provided herein or in the Restricted Stock Award Certificate. Except as may otherwise be provided by the Administrator either in
the Award Certificate or, subject to Section 16 below, in writing after the Award is issued, if a grantee’s employment
(or other Service Relationship) with the Company and its Subsidiaries terminates for any reason, any Restricted Shares that have
not vested at the time of termination shall automatically and without any requirement of notice to such grantee from or other action
by or on behalf of, the Company be deemed to have been reacquired by the Company at their original purchase price (if any) from
such grantee or such grantee’s legal representative simultaneously with such termination of employment (or other Service
Relationship), and thereafter shall cease to represent any ownership of the Company by the grantee or rights of the grantee as
a stockholder. Following such deemed reacquisition of Restricted Shares that are represented by physical certificates, a grantee
shall surrender such certificates to the Company upon request without consideration.


 


(d)          Vesting
of Restricted Shares. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established
performance goals, objectives and other conditions on which the non-transferability of the Restricted Shares and the Company’s
right of repurchase or forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance
goals, objectives and other conditions, the shares on which all restrictions have lapsed shall no longer be Restricted Shares and
shall be deemed “vested.”


 






    	 	10	 



     


    

 


SECTION 8. RESTRICTED
STOCK UNITS


 


(a)          Nature
of Restricted Stock Units. The Administrator may grant Restricted Stock Units under the Plan. A Restricted Stock Unit is an
Award of stock units that may be settled in shares of Stock (or cash, to the extent explicitly provided for in the Award Certificate)
upon the satisfaction of such restrictions and conditions at the time of grant. Conditions may be based on continuing employment
(or other Service Relationship) and/or achievement of pre-established performance goals and objectives. The terms and conditions
of each such Award shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and
grantees. Except in the case of Restricted Stock Units with a deferred settlement date that complies with Section 409A, at
the end of the vesting period, the Restricted Stock Units, to the extent vested, shall be settled in the form of shares of Stock
(or cash, to the extent explicitly provided for in the Award Certificate). Restricted Stock Units with deferred settlement dates
are subject to Section 409A and shall contain such additional terms and conditions as the Administrator shall determine in
its sole discretion in order to comply with the requirements of Section 409A.


 


(b)          Election
to Receive Restricted Stock Units in Lieu of Compensation. The Administrator may, in its sole discretion, permit a grantee
to elect to receive a portion of future cash compensation otherwise due to such grantee in the form of an award of Restricted Stock
Units. Any such election shall be made in writing and shall be delivered to the Company no later than the date specified by the
Administrator and in accordance with Section 409A and such other rules and procedures established by the Administrator.
Any such future cash compensation that the grantee elects to defer shall be converted to a fixed number of Restricted Stock Units
based on the Fair Market Value of Stock on the date the compensation would otherwise have been paid to the grantee if such payment
had not been deferred as provided herein. The Administrator shall have the sole right to determine whether and under what circumstances
to permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate.
Any Restricted Stock Units that are elected to be received in lieu of cash compensation shall be fully vested, unless otherwise
provided in the Award Certificate.


 


(c)          Rights
as a Stockholder. A grantee shall have the rights as a stockholder only as to shares of Stock acquired by the grantee upon
settlement of Restricted Stock Units; provided, however, that the grantee may be credited with Dividend Equivalent Rights with
respect to the stock units underlying his or her Restricted Stock Units, subject to the provisions of Section 11 and such
terms and conditions as the Administrator may determine.


 


(d)          Termination.
Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 16 below,
in writing after the Award is issued, a grantee’s right in all Restricted Stock Units that have not vested shall automatically
terminate upon the grantee’s termination of employment (or cessation of Service Relationship) with the Company and its Subsidiaries
for any reason.

SECTION 9. UNRESTRICTED
STOCK AWARDS


 


Grant or Sale of Unrestricted Stock.
The Administrator may grant (or sell at par value or such higher purchase price determined by the Administrator) an Unrestricted
Stock Award under the Plan. An Unrestricted Stock Award is an Award pursuant to which the grantee may receive shares of Stock free
of any restrictions under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration,
or in lieu of cash compensation due to such grantee.


 


SECTION 10. CASH-BASED
AWARDS


 


Grant of Cash-Based Awards. The Administrator
may grant Cash-Based Awards under the Plan. A Cash-Based Award is an Award that entitles the grantee to a payment in cash upon
the attainment of specified performance goals. The Administrator shall determine the maximum duration of the Cash-Based Award,
the amount of cash to which the Cash-Based Award pertains, the conditions upon which the Cash-Based Award shall become vested or
payable, and such other provisions as the Administrator shall determine. Each Cash-Based Award shall specify a cash-denominated
payment amount, formula or payment ranges as determined by the Administrator. Payment, if any, with respect to a Cash-Based Award
shall be made in accordance with the terms of the Award and may be made in cash.


 


SECTION 11. DIVIDEND
EQUIVALENT RIGHTS


 


(a)          Dividend
Equivalent Rights. The Administrator may grant Dividend Equivalent Rights under the Plan. A Dividend Equivalent Right is an
Award entitling the grantee to receive credits based on cash dividends that would have been paid on the shares of Stock specified
in the Dividend Equivalent Right (or other Award to which it relates) if such shares had been issued to the grantee. A Dividend
Equivalent Right may be granted hereunder to any grantee as a component of an award of Restricted Stock Units or as a freestanding
award. The terms and conditions of Dividend Equivalent Rights shall be specified in the Award Certificate. Dividend equivalents
credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be reinvested in additional shares
of Stock, which may thereafter accrue additional equivalents. Any such reinvestment shall be at Fair Market Value on the date of
reinvestment or such other price as may then apply under a dividend reinvestment plan sponsored by the Company, if any. Dividend
Equivalent Rights may be settled in cash or shares of Stock or a combination thereof, in a single installment or installments.
A Dividend Equivalent Right granted as a component of an Award of Restricted Stock Units shall provide that such Dividend Equivalent
Right shall be settled only upon settlement or payment of, or lapse of restrictions on, such other Award, and that such Dividend
Equivalent Right shall expire or be forfeited or annulled under the same conditions as such other Award.


 


(b)          Termination.
Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 16 below,
in writing after the Award is issued, a grantee’s rights in all Dividend Equivalent Rights shall automatically terminate
upon the grantee’s termination of employment (or cessation of Service Relationship) with the Company and its Subsidiaries
for any reason.

SECTION 12. Transferability
of Awards


 


(a)          Transferability.
Except as provided in Section 12(b) below, during a grantee’s lifetime, his or her Awards shall be exercisable
only by the grantee, or by the grantee’s legal representative or guardian in the event of the grantee’s incapacity.
No Awards shall be sold, assigned, transferred or otherwise encumbered or disposed of by a grantee other than by will or by the
laws of descent and distribution or pursuant to a domestic relations order. No Awards shall be subject, in whole or in part, to
attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be null and void.


 


(b)          Administrator
Action. Notwithstanding Section 12(a), the Administrator, in its discretion, may provide either in the Award Certificate
regarding a given Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or
her Non-Qualified Stock Options to his or her immediate family members, to trusts for the benefit of such family members, or to
partnerships in which such family members are the only partners, provided that the transferee agrees in writing with the Company
to be bound by all of the terms and conditions of this Plan and the applicable Award. In no event may an Award be transferred by
a grantee for value.


 


(c)          Family
Member. For purposes of Section 12(b), “family member” shall mean a grantee’s child, stepchild, grandchild,
parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law,
brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the grantee’s household (other than
a tenant of the grantee), a trust in which these persons (or the grantee) have more than 50 percent of the beneficial interest,
a foundation in which these persons (or the grantee) control the management of assets, and any other entity in which these persons
(or the grantee) own more than 50 percent of the voting interests.


 


(d)          Designation
of Beneficiary. To the extent permitted by the Company, each grantee to whom an Award has been made under the Plan may designate
a beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee’s
death. Any such designation shall be on a form provided for that purpose by the Administrator and shall not be effective until
received by the Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries
have predeceased the grantee, the beneficiary shall be the grantee’s estate.


 


SECTION 13. TAX
WITHHOLDING


 


(a)          Payment
by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Stock or other amount received
thereunder first becomes includable in the gross income of the grantee for income tax purposes, pay to the Company, or make arrangements
satisfactory to the Administrator regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld
by the Company with respect to such income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right
to deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company’s obligation to deliver evidence
of book entry (or stock certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied
by the grantee.


 






    	 	13	 



     


    

 


(b)          Payment
in Stock. The Administrator may require the Company’s tax withholding obligation to be satisfied, in whole or in part,
by the Company withholding from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market
Value (as of the date the withholding is effected) that would satisfy the withholding amount due; provided, however, that the amount
withheld does not exceed the maximum statutory tax rate or such lesser amount as is necessary to avoid liability accounting treatment.
For purposes of share withholding, the Fair Market Value of withheld shares shall be determined in the same manner as the value
of Stock includible in income of the grantees. The Administrator may also require the Company’s tax withholding obligation
to be satisfied, in whole or in part, by an arrangement whereby a certain number of shares of Stock issued pursuant to any Award
are immediately sold and proceeds from such sale are remitted to the Company in an amount that would satisfy the withholding amount
due.


 


SECTION 14. Section 409A
awards


 


Awards are intended to be exempt from Section 409A
to the greatest extent possible and to otherwise comply with Section 409A. The Plan and all Awards shall be interpreted in
accordance with such intent. To the extent that any Award is determined to constitute “nonqualified deferred compensation”
within the meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and
requirements as specified by the Administrator from time to time in order to comply with Section 409A. In this regard, if
any amount under a 409A Award is payable upon a “separation from service” (within the meaning of Section 409A)
to a grantee who is then considered a “specified employee” (within the meaning of Section 409A), then no such
payment shall be made prior to the date that is the earlier of (i) six months and one day after the grantee’s separation
from service, or (ii) the grantee’s death, but only to the extent such delay is necessary to prevent such payment from
being subject to interest, penalties and/or additional tax imposed pursuant to Section 409A. Further, the settlement of any
409A Award may not be accelerated except to the extent permitted by Section 409A. The Company makes no representation that
any or all of the payments or benefits described in the Plan will be exempt from or comply with Section 409A of the Code and
makes no undertaking to preclude Section 409A of the Code from applying to any such payment. The grantee shall be solely responsible
for the payment of any taxes and penalties incurred under Section 409A.


 


SECTION 15. TERMINATION
OF SERVICE RELATIONSHIP, TRANSFER, LEAVE OF ABSENCE, ETC.


 


(a)          Termination
of Service Relationship. If the grantee’s Service Relationship is with an Affiliate and such Affiliate ceases to be an
Affiliate, the grantee shall be deemed to have terminated his or her Service Relationship for purposes of the Plan.


 


(b)          For
purposes of the Plan, the following events shall not be deemed a termination of a Service Relationship:


 


(i)          a
transfer to the employment of the Company from an Affiliate or from the Company to an Affiliate, or from one Affiliate to another;
or


 






    	 	14	 



     


    

 


(ii)         an
approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s
right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence
was granted or if the Administrator otherwise so provides in writing.


 


SECTION 16. AMENDMENTS
AND TERMINATION


 


The Board may, at any time, amend or discontinue
the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in
law or for any other lawful purpose, but no such action shall materially and adversely affect rights under any outstanding Award
without the holder’s consent. The Administrator is specifically authorized to exercise its discretion to reduce the exercise
price of outstanding Stock Options or Stock Appreciation Rights or effect the repricing of such Awards through cancellation and
re-grants. To the extent required under the rules of any securities exchange or market system on which the Stock is listed,
to the extent determined by the Administrator to be required by the Code to ensure that Incentive Stock Options granted under the
Plan are qualified under Section 422 of the Code, Plan amendments shall be subject to approval by Company stockholders. Nothing
in this Section 16 shall limit the Administrator’s authority to take any action permitted pursuant to Section 3(b) or
3(c).


 


SECTION 17. STATUS
OF PLAN


 


With respect to the portion of any Award
that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have
no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine
in connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other
arrangements to meet the Company’s obligations to deliver Stock or make payments with respect to Awards hereunder, provided
that the existence of such trusts or other arrangements is consistent with the foregoing sentence.


 


SECTION 18. GENERAL
PROVISIONS


 


(a)          No
Distribution. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with
the Company in writing that such person is acquiring the shares without a view to distribution thereof.


 


(b)          Issuance
of Stock. To the extent certificated, stock certificates to grantees under this Plan shall be deemed delivered for all purposes
when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed
to the grantee, at the grantee’s last known address on file with the Company. Uncertificated Stock shall be deemed delivered
for all purposes when the Company or a Stock transfer agent of the Company shall have given to the grantee by electronic mail (with
proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last known address on file with the
Company, notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records).
Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any evidence of book entry
or certificates evidencing shares of Stock pursuant to the exercise or settlement of any Award, unless and until the Administrator
has determined, with advice of counsel (to the extent the Administrator deems such advice necessary or advisable), that the issuance
and delivery is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements
of any exchange on which the shares of Stock are listed, quoted or traded. Any Stock issued pursuant to the Plan shall be subject
to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with federal, state
or foreign jurisdiction, securities or other laws, rules and quotation system on which the Stock is listed, quoted or traded.
The Administrator may place legends on any Stock certificate or notations on any book entry to reference restrictions applicable
to the Stock. In addition to the terms and conditions provided herein, the Administrator may require that an individual make such
reasonable covenants, agreements, and representations as the Administrator, in its discretion, deems necessary or advisable in
order to comply with any such laws, regulations, or requirements. The Administrator shall have the right to require any individual
to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a window-period
limitation, as may be imposed in the discretion of the Administrator.


 






    	 	15	 



     


    

 


(c)          No
Fractional Shares. No fractional shares of Stock shall be issued or delivered pursuant to the Plan or any Award, and the Administrator
shall determine whether cash, other securities or other property shall be paid or transferred in lieu of any fractional shares,
or whether such fractional shares or any rights thereto shall be canceled, terminated or otherwise eliminated


 


(d)          Stockholder
Rights. Until Stock is deemed delivered in accordance with Section 18(b), no right to vote or receive dividends or any
other rights of a stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding
the exercise of a Stock Option or any other action by the grantee with respect to an Award.


 


(e)          Other
Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other
or additional compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable
only in specific cases. The adoption of this Plan and the grant of Awards do not confer upon any employee any right to continued
employment with the Company or any Subsidiary.


 


(f)           Trading
Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading
policies and procedures, as in effect from time to time.


 


(g)          Clawback.
All Awards shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with (i) any
clawback, forfeiture or other similar policy adopted by the Board or Administrator and as in effect from time to time; and (ii) applicable
law.

the Grantee, and any shares of Stock issuable with respect to the Award may not be sold, transferred, pledged, assigned or otherwise
encumbered or disposed of until (i) the Restricted Stock Units have vested as provided in Paragraph 2 of this Agreement and
(ii) shares of Stock have been issued to the Grantee in accordance with the terms of the Plan and this Agreement.


 


2.            Vesting
of Restricted Stock Units. The restrictions and conditions of Paragraph 1 of this Agreement shall lapse on the Vesting
Date or Dates specified in the following schedule so long as the Grantee remains in a Service Relationship on such Vesting Dates.
If a series of Vesting Dates is specified, then the restrictions and conditions in Paragraph 1 shall lapse only with respect
to the number of Restricted Stock Units specified as vested on such date.

3.            Termination
of Service Relationship. If the Grantee’s Service Relationship terminates for any reason (including death or disability)
prior to the satisfaction of the vesting conditions set forth in Paragraph 2 above, any Restricted Stock Units that have not vested
as of such date shall automatically and without notice terminate and be forfeited, and neither the Grantee nor any of his or her
successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such unvested Restricted
Stock Units.


 






    


     


    

 


4.            Issuance
of Shares of Stock. As soon as practicable following each Vesting Date (but in no event later than two and one-half months
after the end of the year in which the Vesting Date occurs), the Company shall issue to the Grantee the number of shares of Stock
equal to the aggregate number of Restricted Stock Units that have vested pursuant to Paragraph 2 of this Agreement on such date
and the Grantee shall thereafter have all the rights of a stockholder of the Company with respect to such shares.


 


5.            Incorporation

and local taxes required by law to be withheld on account of such taxable event. The Company shall have the authority to cause
the required tax withholding obligation to be satisfied, in whole or in part, by (i) withholding from shares of Stock to be
issued to the Grantee a number of shares of Stock with an aggregate Fair Market Value that would satisfy the withholding amount
due; or (ii) causing its transfer agent to sell from the number of shares of Stock to be issued to the Grantee, the number
of shares of Stock necessary to satisfy the Federal, state and local taxes required by law to be withheld from the Grantee on account
of such transfer.


 


7.            Section 409A
of the Code. This Agreement shall be interpreted in such a manner that all provisions relating to the settlement of the Award
are exempt from the requirements of Section 409A of the Code as “short-term deferrals” as described in Section 409A

Obligation to Continue Service Relationship. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan
or this Agreement to continue the Grantee’s employment or other Service Relationship with the Company or a Subsidiary and
neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to terminate the
Grantee’s employment or other Service Relationship with the Company or a Subsidiary at any time.

Pursuant to the 908
Devices Inc. 2020 Stock Option and Incentive Plan, as amended through the date hereof (the “Plan”), 908 Devices Inc.
(the “Company”) hereby grants to the Optionee named above an option (the “Stock Option”) to purchase on

(the “Stock”), of the Company specified above at the Option Exercise Price per Share specified above subject to the
terms and conditions set forth herein and in the Plan. This Stock Option is not intended to be an “incentive stock option”
under Section 422 of the Internal Revenue Code of 1986, as amended.


 


1.            Exercisability
Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except as set
forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability
schedule hereunder, this Stock Option shall be exercisable with respect to the following number of Option Shares on the dates indicated
so long as the Optionee remains in a Service Relationship on such dates:


 


	 	Incremental Number of

Option Shares Exercisable	 	Exercisability Date	 
	 	 	 	 	 
	 	_____________ (___%)	 	____________	 
	 	_____________ (___%)	 	____________	 
	 	_____________ (___%)	 	____________	 
	 	_____________ (___%)	 	____________	 


 


Once exercisable, this
Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject
to the provisions hereof and of the Plan.


 






    


     


    

 


2.            Manner
of Exercise.


 


(a)            The
Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this
Stock Option, the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option
Shares purchasable at the time of such notice. This notice shall specify the number of Option Shares to be purchased.


 


Payment of the purchase
price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or
other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of
Stock that have been purchased by the Optionee on the open market or that are beneficially owned by the Optionee and are not then
subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator;
(iii)  by the Optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions
to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company to pay the option purchase
price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee and the broker
shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe
as a condition of such payment procedure; (iv)  by a “net exercise” arrangement pursuant to which the Company
will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value
that does not exceed the aggregate exercise price; or (v) a combination of (i), (ii), (iii) and (iv) above. Payment
instruments will be received subject to collection.


 


The transfer to the
Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company’s
receipt from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any
other requirements contained herein or in the Plan or in any other agreement or provision of laws, and (iii) the receipt by
the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock
to be purchased pursuant to the exercise of Stock Options under the Plan and any subsequent resale of the shares of Stock will
be in compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase price by previously-owned
shares of Stock through the attestation method, the number of shares of Stock transferred to the Optionee upon the exercise of
the Stock Option shall be net of the Shares attested to.


 


(b)            The
shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company
or of the transfer agent upon compliance to the satisfaction of the Administrator with all requirements under applicable laws or
regulations in connection with such transfer and with the requirements hereof and of the Plan. The determination of the Administrator
as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be the holder of, or to have
any of the rights of a holder with respect to, any shares of Stock subject to this Stock Option unless and until this Stock Option
shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have transferred the shares to
the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon,
the Optionee shall have full voting, dividend and other ownership rights with respect to such shares of Stock.

(c)            The
minimum number of shares with respect to which this Stock Option may be exercised at any one time shall be 100 shares, unless the
number of shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under
this Stock Option at the time.


 


(d)            Notwithstanding
any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date hereof.


 


3.            Termination
of Service Relationship. If the Optionee’s Service Relationship terminates, the period within which to exercise the Stock
Option may be subject to earlier termination as set forth below.


 


(a)            Termination
Due to Death. If the Optionee’s Service Relationship terminates by reason of the Optionee’s death, any portion
of this Stock Option outstanding on such date, to the extent exercisable on the date of death, may thereafter be exercised by the
Optionee’s legal representative or legatee for a period of 12 months from the date of death or until the Expiration Date,
if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall terminate immediately and be of
no further force or effect.


 


(b)            Termination
Due to Disability. If the Optionee’s Service Relationship terminates by reason of the Optionee’s disability (as
determined by the Administrator), any portion of this Stock Option outstanding on such date, to the extent exercisable on the date
of such termination, may thereafter be exercised by the Optionee for a period of 12 months from the date of disability or until
the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of disability shall terminate
immediately and be of no further force or effect.


 


(c)            Termination
for Cause. If the Optionee’s Service Relationship terminates for Cause, any portion of this Stock Option outstanding
on such date shall terminate immediately and be of no further force and effect. For purposes hereof, “Cause” shall
mean, unless otherwise provided in an employment or other service agreement between the Company and the Optionee, a determination
by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by the Optionee of any agreement
between the Optionee and the Company; (ii) the conviction of, indictment for or plea of nolo contendere by the Optionee to
a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate non-performance
(other than by reason of disability) by the Optionee of the Optionee’s duties to the Company.


 


(d)            Other
Termination. If the Optionee’s Service Relationship terminates for any reason other than the Optionee’s death,
the Optionee’s disability or Cause, and unless otherwise determined by the Administrator, any portion of this Stock Option
outstanding on such date may be exercised, to the extent exercisable on the date of termination, for a period of three months from
the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the
date of termination shall terminate immediately and be of no further force or effect.


 






    3


     


    

 


The Administrator’s
determination of the reason for termination of the Optionee’s Service Relationship shall be conclusive and binding on the
Optionee and his or her representatives or legatees.


 


4.            Incorporation
of Plan. Notwithstanding anything herein to the contrary, this Stock Option shall be subject to and governed by all the terms
and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized
terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein.


 


5.            Transferability.
This Agreement is personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise,
other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee’s lifetime,
only by the Optionee, and thereafter, only by the Optionee’s legal representative or legatee.


 


6.            Tax
Withholding. The Optionee shall, not later than the date as of which the exercise of this Stock Option becomes a taxable event
for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal,
state, and local taxes required by law to be withheld on account of such taxable event. The Company shall have the authority to
cause the required tax withholding obligation to be satisfied, in whole or in part, by (i) withholding from shares of Stock
to be issued to the Optionee a number of shares of Stock with an aggregate Fair Market Value that would satisfy the withholding
amount due; or (ii) causing its transfer agent to sell from the number of shares of Stock to be issued to the Optionee, the
number of shares of Stock necessary to satisfy the Federal, state and local taxes required by law to be withheld from the Optionee
on account of such transfer.


 


7.            No
Obligation to Continue Service Relationship. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan
or this Agreement to continue the Optionee’s employment or other Service Relationship with the Company or a Subsidiary and
neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to terminate the
Optionee’s employment or other Service Relationship with the Company or a Subsidiary at any time.


 


8.            Integration.
This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all prior
agreements and discussions between the parties concerning such subject matter.

Pursuant to the 908

(the “Company”) hereby grants to the Optionee named above an option (the “Stock Option”) to purchase on

(the “Stock”), of the Company specified above at the Option Exercise Price per Share specified above subject to the
terms and conditions set forth herein and in the Plan.


 


1.            Exercisability
Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except as set
forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability
schedule hereunder, this Stock Option shall be exercisable with respect to the following number of Option Shares on the dates indicated
so long as the Optionee remains in a Service Relationship on such dates:


 


	 	Incremental Number of

Option Shares Exercisable*	 	Exercisability Date	 
	 	 	 	 	 
	 	_____________ (___%)	 	____________	 
	 	_____________ (___%)	 	____________	 
	 	_____________ (___%)	 	____________	 
	 	_____________ (___%)	 	____________	 
	 	_____________ (___%)	 	____________	 
	 	 	 	 	 
	 	* Max. of $100,000 per yr.	 	 	 


 


Once exercisable, this
Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject
to the provisions hereof and of the Plan.


 






    


     


    

 


2.            Manner
of Exercise.


 


(a)            The
Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this
Stock Option, the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option
Shares purchasable at the time of such notice. This notice shall specify the number of Option Shares to be purchased.


 


Payment of the purchase
price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or
other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of
Stock that have been purchased by the Optionee on the open market or that are beneficially owned by the Optionee and are not then
subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator;
(iii) by the Optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions
to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company to pay the option purchase
price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee and the broker
shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe
as a condition of such payment procedure; or (iv) a combination of (i), (ii) and (iii) above. Payment instruments
will be received subject to collection.


 


The transfer to the
Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company’s
receipt from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any
other requirements contained herein or in the Plan or in any other agreement or provision of laws, and (iii) the receipt by
the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock
to be purchased pursuant to the exercise of Stock Options under the Plan and any subsequent resale of the shares of Stock will
be in compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase price by previously-owned
shares of Stock through the attestation method, the number of shares of Stock transferred to the Optionee upon the exercise of
the Stock Option shall be net of the Shares attested to.


 


(b)            The
shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company
or of the transfer agent upon compliance to the satisfaction of the Administrator with all requirements under applicable laws or
regulations in connection with such transfer and with the requirements hereof and of the Plan. The determination of the Administrator
as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be the holder of, or to have
any of the rights of a holder with respect to, any shares of Stock subject to this Stock Option unless and until this Stock Option
shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have transferred the shares to
the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon,
the Optionee shall have full voting, dividend and other ownership rights with respect to such shares of Stock.


 






    2


     


    

 


(c)            The
minimum number of shares with respect to which this Stock Option may be exercised at any one time shall be 100 shares, unless the
number of shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under
this Stock Option at the time.


 


(d)            Notwithstanding
any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date hereof.


 


3.            Termination
of Service Relationship. If the Optionee’s Service Relationship terminates, the period within which to exercise the Stock
Option may be subject to earlier termination as set forth below.


 


(a)            Termination
Due to Death. If the Optionee’s Service Relationship terminates by reason of the Optionee’s death, any portion
of this Stock Option outstanding on such date, to the extent exercisable on the date of death, may thereafter be exercised by the
Optionee’s legal representative or legatee for a period of 12 months from the date of death or until the Expiration Date,
if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall terminate immediately and be of
no further force or effect.


 


(b)            Termination
Due to Disability. If the Optionee’s Service Relationship terminates by reason of the Optionee’s disability (as
determined by the Administrator), any portion of this Stock Option outstanding on such date, to the extent exercisable on the date
of such termination, may thereafter be exercised by the Optionee for a period of 12 months from the date of disability or until
the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of disability shall terminate
immediately and be of no further force or effect.


 


(c)            Termination
for Cause. If the Optionee’s Service Relationship terminates for Cause, any portion of this Stock Option outstanding
on such date shall terminate immediately and be of no further force and effect. For purposes hereof, “Cause” shall
mean, unless otherwise provided in an employment or other service agreement between the Company and the Optionee, a determination
by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by the Optionee of any agreement
between the Optionee and the Company; (ii) the conviction of, indictment for or plea of nolo contendere by the Optionee to
a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate non-performance
(other than by reason of disability) by the Optionee of the Optionee’s duties to the Company.


 


(d)            Other
Termination. If the Optionee’s Service Relationship terminates for any reason other than the Optionee’s death,
the Optionee’s disability, or Cause, and unless otherwise determined by the Administrator, any portion of this Stock Option
outstanding on such date may be exercised, to the extent exercisable on the date of termination, for a period of three months from
the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the
date of termination shall terminate immediately and be of no further force or effect.


 






    3


     


    

 


The Administrator’s
determination of the reason for termination of the Optionee’s Service Relationship shall be conclusive and binding on the
Optionee and his or her representatives or legatees.


 


4.            Incorporation
of Plan. Notwithstanding anything herein to the contrary, this Stock Option shall be subject to and governed by all the terms
and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized
terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein.


 


5.            Transferability.
This Agreement is personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise,
other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee’s lifetime,
only by the Optionee, and thereafter, only by the Optionee’s legal representative or legatee.


 


6.            Status
of the Stock Option. This Stock Option is intended to qualify as an “incentive stock option” under Section 422
of the Internal Revenue Code of 1986, as amended (the “Code”), but the Company does not represent or warrant that this
Stock Option qualifies as such. The Optionee should consult with his or her own tax advisors regarding the tax effects of this
Stock Option and the requirements necessary to obtain favorable income tax treatment under Section 422 of the Code, including,
but not limited to, holding period requirements and that this Stock Option must be exercised within three months after termination
of employment as an employee (or 12 months in the case of death or disability) to qualify as an “incentive stock option.”
To the extent any portion of this Stock Option does not so qualify as an “incentive stock option,” such portion shall
be deemed to be a non-qualified stock option. If the Optionee intends to dispose or does dispose (whether by sale, gift, transfer
or otherwise) of any Option Shares within the one-year period beginning on the date after the transfer of such shares to him or
her, or within the two-year period beginning on the day after the grant of this Stock Option, he or she will so notify the Company
within 30 days after such disposition.


 


7.            Tax
Withholding. The Optionee shall, not later than the date as of which the exercise of this Stock Option becomes a taxable event
for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal,
state, and local taxes required by law to be withheld on account of such taxable event. The Company shall have the authority to
cause the required tax withholding obligation to be satisfied, in whole or in part, by (i) withholding from shares of Stock
to be issued to the Optionee a number of shares of Stock with an aggregate Fair Market Value that would satisfy the withholding
amount due; or (ii) causing its transfer agent to sell from the number of shares of Stock to be issued to the Optionee, the
number of shares of Stock necessary to satisfy the Federal, state and local taxes required by law to be withheld from the Optionee
on account of such transfer.


 


8.            No
Obligation to Continue Service Relationship. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan
or this Agreement to continue the Optionee’s employment or other Service Relationship with the Company or a Subsidiary and
neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to terminate the
Optionee’s employment or other Service Relationship with the Company or a Subsidiary at any time.


 






    4


     


    

 


9.            Integration.
This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all prior
agreements and discussions between the parties concerning such subject matter.


 


10.            Data
Privacy Consent. In order to administer the Plan and this Agreement and to implement or structure future equity grants, the
Company, its subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process
any and all personal or professional data, including but not limited to Social Security or other identification number, home address
and telephone number, date of birth and other information that is necessary or desirable for the administration of the Plan and/or
this Agreement (the “Relevant Information”). By entering into this Agreement, the Optionee (i) authorizes the
Company to collect, process, register and transfer to the Relevant Companies all Relevant Information; (ii) waives any privacy
rights the Optionee may have with respect to the Relevant Information; (iii) authorizes the Relevant Companies to store and
transmit such information in electronic form; and (iv) authorizes the transfer of the Relevant Information to any jurisdiction
in which the Relevant Companies consider appropriate. The Optionee shall have access to, and the right to change, the Relevant
Information. Relevant Information will only be used in accordance with applicable law.
