		2.	PURPOSES OF THE PLAN.



 


The Plan is intended to encourage ownership of Shares by Employees
and directors of and certain Consultants to the Company and its Affiliates in order to attract and retain such people, to induce them
to work for the benefit of the Company or of an Affiliate and to provide additional incentive for them to promote the success of the Company
or of an Affiliate. The Plan provides for the granting of ISOs, Non-Qualified Options, Stock Grants and Stock-Based Awards.


 


		3.	SHARES SUBJECT TO THE PLAN.



 


		(a)	The number of Shares which may be issued from time to time pursuant to this Plan shall be the sum of: (i) 13,000,000 shares of
Common Stock and (ii) the number of shares of Common Stock remaining under this Plan as of April 1, 2022, and (iii) any
shares of Common Stock that are represented by awards granted under this Plan, the Company’s 2006 or 2016 Employee, Director and
Consultant Equity Incentive Plans that are forfeited, expire, or are cancelled without delivery of shares of Common Stock or which result
in the forfeiture of shares of Common Stock back to the Company on or after April 1, 2022 (but in no event more than 28,742,013 Shares
shall be added to the Plan pursuant to clauses (ii) and (iii)), or the equivalent of such number of Shares after the Administrator,
in its sole discretion, has interpreted the effect of any stock split, stock dividend, combination, recapitalization or similar transaction
in accordance with Paragraph 25 of this Plan.



 






    -4-


     


    

 


		(b)	If an Option ceases to be “outstanding”, in whole or in part (other than by exercise), or if the Company shall reacquire
(at not more than its original issuance price) any Shares issued pursuant to a Stock Grant or Stock-Based Award, or if any Stock Right
expires or is forfeited, cancelled, or otherwise terminated or results in any Shares not being issued, the unissued or reacquired Shares
which were subject to such Stock Right shall again be available for issuance from time to time pursuant to this Plan. Notwithstanding
the foregoing, if a Stock Right is exercised, in whole or in part, by tender of Shares or if the Company’s or an Affiliate’s
tax withholding obligation is satisfied by withholding Shares, the number of Shares deemed to have been issued under the Plan for purposes
of the limitations set forth in Paragraph 3(a) above shall be the number of Shares that were subject to the Stock Right or portion
thereof, and not the net number of Shares actually issued and any stock appreciation right to be settled in shares of Common Stock shall
be counted in full against the number of Shares available for issuance under the Plan, regardless of the number of exercise gain shares
issued upon settlement of the stock appreciation right. In addition, Shares repurchased by the Company with the proceeds of the option
exercise price may not be reissued under the Plan.



  


		(c)	For purposes of determining the number of Shares available for issuance under Paragraph 3(a) above, (i) for the grant of
any Option or similar Stock- Based Award one Share for each Share actually subject to such Option or similar Stock-Based Award shall be
deducted, and (ii) for the grant of any Full Value Award, one and one-quarter
(1.25) Shares for each Share actually subject to any such Full Value Award shall be deducted. If a Full Value Award expires, is forfeited,
or otherwise lapses, the Shares that were subject to the Full Value Award shall be restored to the total number of Shares available for
grant as were deducted as Full Value Awards pursuant to this paragraph. Except in the case of death, disability or Change of Control,
or as provided in the next sentence, no Stock Right shall vest, and no right of the Company to restrict or reacquire Shares subject to
Full Value Awards shall lapse, less than one (1) year from the date of grant. Notwithstanding the foregoing, Stock Rights may be
granted having time-based vesting of less than one (1) year from the date of grant so long as no more than five percent (5%) of the
Shares reserved for issuance under the Plan pursuant to Paragraph 3(a) above (as adjusted under Paragraph 25 of this Plan) may be
granted in the aggregate pursuant to such awards.






 


		4.	ADMINISTRATION OF THE PLAN.



 


The Administrator of the Plan will be the Board of Directors, except
to the extent the Board of Directors delegates its authority to the Committee, in which case the Committee shall be the Administrator.
Subject to the provisions of the Plan, the Administrator is authorized to:


 


		(a)	Interpret the provisions of the Plan and all Stock Rights and to make all rules and determinations which it deems necessary or
advisable for the administration of the Plan;



 






    -5-


     


    

 


		(b)	Determine which Employees, directors and Consultants shall be granted Stock Rights;



 


		(c)	Determine the number of Shares for which a Stock Right or Stock Rights shall be granted provided, that the aggregate grant date fair
value of Shares to be granted to any non-employee director under the Plan in any calendar year may not exceed $500,000 dollars except
that the foregoing limitation on Stock Rights granted to non-employee directors shall not apply to Stock Rights made pursuant to an election
by a non-employee director to receive the Stock Right in lieu of cash for all or a portion of cash fees to be received for service on
the Board of Directors or any Committee thereof.



 


		(d)	Specify the terms and conditions upon which a Stock Right or Stock Rights may be granted;



 


		(e)	Make any adjustments in the Performance Goals included in any Performance-Based Awards;



 


		(f)	Amend any term or condition of any outstanding Stock Right, other than reducing the exercise price or purchase price or extending
the expiration date of an Option, provided that (i) such term or condition as amended is not prohibited by the Plan; (ii) any
such amendment shall not impair the rights of a Participant under any Stock Right previously granted without such Participant’s
consent or in the event of death of the Participant the Participant’s Survivors; and (iii) any such amendment shall be
made only after the Administrator determines whether such amendment would cause any adverse tax consequences to the Participant, including,
but not limited to, the annual vesting limitation contained in Section 422(d) of the Code and described in Paragraph 6(b)(iv) below
with respect to ISOs and pursuant to Section 409A of the Code; and



 


		(g)	Adopt any sub-plans applicable to residents of any specified jurisdiction as it deems necessary or appropriate in order to comply
with or take advantage of any tax or other laws applicable to the Company or to Plan Participants or to otherwise facilitate the administration
of the Plan, which sub-plans may include additional restrictions or conditions applicable to Stock Rights or Shares issuable pursuant
to a Stock Right;



 


provided, however, that all such interpretations, rules, determinations,
terms and conditions shall be made and prescribed in the context of (i) preserving the tax status under Section 422 of the Code
of those Options which are designated as ISOs; and (ii) not causing any adverse tax consequences under Section 409A of
the Code. Subject to the foregoing, the interpretation and construction by the Administrator of any provisions of the Plan or of any Stock
Right granted under it shall be final, unless otherwise determined by the Board of Directors, if the Administrator is the Committee. In
addition, if the Administrator is the Committee, the Board of Directors may take any action under the Plan that would otherwise be the
responsibility of the Committee.


 






    -6-


     


    

 


To the extent permitted under applicable law, the Board of
Directors or the Committee may allocate all or any portion of its responsibilities and powers to any one or more of its members and
may delegate all or any portion of its responsibilities and powers to any other person selected by it; provided that only a
Committee consisting solely of non-employee directors (or the full Board when only non-employee directors are present and voting)
shall have the authority to grant Options, Stock Grants or Stock-Based Awards to non-employee directors, or to amend the terms of
any such awards in a manner that would accelerate the exercisability or vesting of, or lapsing of any right by the Company to
restrict or reacquire Shares subject to, all or any portion of any such award. The Board of Directors or the Committee may revoke
any such allocation or delegation at any time.


  


		5.	ELIGIBILITY FOR PARTICIPATION.



 


The Administrator will, in its sole discretion, name the Participants
in the Plan, provided, however, that each Participant must be an Employee, director or Consultant of the Company or of an Affiliate at
the time a Stock Right is granted. Notwithstanding the foregoing, the Administrator may authorize the grant of a Stock Right to a person
not then an Employee, director or Consultant of the Company or of an Affiliate; provided, however, that the actual grant of such
Stock Right shall be conditioned upon such person becoming eligible to become a Participant at or prior to the time of the execution of
the Agreement evidencing such Stock Right. ISOs may be granted only to Employees who are deemed residents of the United States for tax
purposes. Non-Qualified Options, Stock Grants and Stock-Based Awards may be granted to any Employee, director or Consultant of the Company
or an Affiliate. The granting of any Stock Right to any individual shall neither entitle that individual to, nor disqualify him or her
from, participation in any other grant of Stock Rights or any grants under any other benefit plan established by the Company or any Affiliate
for Employees, directors or Consultants.


 


		6.	TERMS AND CONDITIONS OF OPTIONS.



 


Each Option shall be set forth in writing in an Option Agreement, duly
executed by the Company (or provided in electronic form by the Company) and, to the extent required by law or requested by the Company,
by the Participant. The Administrator may provide that Options be granted subject to such terms and conditions, consistent with the terms
and conditions specifically required under this Plan, as the Administrator may deem appropriate including, without limitation, subsequent
approval by the shareholders of the Company of this Plan or any amendments thereto. The Option Agreements shall be subject to at least
the following terms and conditions:


 


		(a)	Non-Qualified Options: Each Option intended to be a Non-Qualified Option shall be subject to the terms and conditions which
the Administrator determines to be appropriate and in the best interest of the Company, subject to the following minimum standards for

exercise price shall be determined by the Administrator but shall not be less than the Fair Market Value per share of Common Stock on
the date of grant of the Option.

or years, or upon the occurrence of certain conditions or the attainment of stated performance goals or events.



 


		(iv)	Option Conditions: Exercise of any Option may be conditioned upon the Participant’s execution of a Share purchase agreement

that:



 


		(A)	The Participant’s or the Participant’s Survivors’ right to sell or transfer the Shares may be restricted; and

that the Shares will bear legends noting any applicable restrictions.



 


		(b)	ISOs: Each Option intended to be an ISO shall be issued only to an Employee and be subject to the following terms and conditions,
with such additional restrictions or changes as the Administrator determines are appropriate but not in conflict with Section 422
of the Code and relevant regulations and rulings of the Internal Revenue Service:



 


		(i)	Minimum standards: The ISO shall meet the minimum standards required of Non-Qualified Options, as described in Paragraph 6(a) above.



 


		(ii)	Exercise Price: Immediately before the ISO is granted, if the Participant owns, directly or by reason of the applicable attribution
rules in Section 424(d) of the Code:



 


		(A)	10% or less of the total combined voting power of all classes of stock of the Company or an Affiliate, the exercise price per share
of the Shares covered by each ISO shall not be less than 100% of the Fair Market Value per share of the Common Stock on the date of the
grant of the ISO; or



 


		(B)	More than 10% of the total combined voting power of all classes of stock of the Company or an Affiliate, the exercise price per share
of the Shares covered by each ISO shall not be less than 110% of the Fair Market Value per share of the Common Stock on the date of the
grant of the ISO.

not more than five years from the date of the grant or at such earlier time as the Option Agreement may provide.



 


		(iv)	Limitation on Yearly Exercise: The Option Agreements shall restrict the amount of ISOs which may become exercisable in any
calendar year (under this or any other ISO plan of the Company or an Affiliate) so that the aggregate Fair Market Value (determined at
the time each ISO is granted) of the stock with respect to which ISOs are exercisable for the first time by the Participant in any calendar
year does not exceed $100,000.



 


		7.	TERMS AND CONDITIONS OF STOCK GRANTS.



 


Each Stock Grant to a Participant shall state the principal terms in
an Agreement, duly executed by the Company (or provided in electronic form by the Company) and, to the extent required by law or requested
by the Company, by the Participant. The Agreement shall be in a form approved by the Administrator and shall contain terms and conditions
which the Administrator determines to be appropriate and in the best interest of the Company, subject to the following minimum standards:


 


		(a)	Each Agreement shall state the purchase price (per share), if any, of the Shares covered by each Stock Grant, which purchase price
shall be determined by the Administrator but shall not be less than the minimum consideration required by the Massachusetts General Corporation
Law on the date of the grant of the Stock Grant;



 


		(b)	Each Agreement shall state the number of Shares to which the Stock Grant pertains;



 


		(c)	Each Agreement shall include the terms of any right of the Company to restrict or reacquire the Shares subject to the Stock Grant,

and



 


		(d)	Dividends (other than stock dividends to be issued pursuant to Section 25 of the Plan) may accrue but shall not be paid prior
to the time, and only to the extent that, the restrictions or rights to reacquire the Shares subject to the Stock Grant lapse.

		8.	TERMS AND CONDITIONS OF OTHER STOCK-BASED AWARDS.



  


The Administrator shall have the right to grant other Stock-Based
Awards based upon the Common Stock having such terms and conditions as the Administrator may determine, including, without
limitation, the grant of Shares based upon certain conditions, the grant of securities convertible into Shares and the grant of
stock appreciation rights, phantom stock awards, or stock units, deferred or otherwise. The principal terms of each Stock-Based
Award shall be set forth in an Agreement, duly executed by the Company (or provided in electronic form by the Company) and, to the
extent required by law or requested by the Company, by the Participant. The Agreement shall be in a form approved by the
Administrator and shall contain terms and conditions which the Administrator determines to be appropriate and in the best interest
of the Company. Each Agreement shall include the terms of any right of the Company including the right to terminate the Stock-Based
Award without the issuance of Shares, the terms of any vesting conditions, Performance Goals or events upon which Shares shall be
issued, provided that dividends (other than stock dividends to be issued pursuant to Section 25 of the Plan) or dividend
equivalents may accrue but shall not be paid prior to and only to the extent that, the Shares subject to the Stock-Based Award vest.
Under no circumstances may the Agreement covering stock appreciation rights (a) have an exercise price (per share) that is less
than the Fair Market Value per share of Common Stock on the date of grant or (b) expire more than ten years following the date
of grant.


 


The Company intends that the Plan and any Stock-Based Awards granted
hereunder be exempt from the application of Section 409A of the Code or meet the requirements of paragraphs (2), (3) and (4) of
subsection (a) of Section 409A of the Code, to the extent applicable, and be operated in accordance with Section 409A so
that any compensation deferred under any Stock-Based Award (and applicable investment earnings) shall not be included in income under
Section 409A of the Code. Any ambiguities in the Plan shall be construed to effect the intent as described in this Paragraph 8.


 


		9.	PERFORMANCE BASED AWARDS.



 


The Committee shall determine whether, with respect to a performance
period, the applicable Performance Goals have been met with respect to a given Participant and, if they have, to so certify and ascertain
the amount of the applicable Performance-Based Award. No Performance-Based Awards will be issued for such performance period until such
certification is made by the Committee. The number of Shares issued in respect of a Performance-Based Award determined by the Committee
for a performance period shall be paid to the Participant at such time as determined by the Committee in its sole discretion after the
end of such performance period and any dividends (other than stock dividends to be issued pursuant to Section 25 of the Plan) or
dividend equivalents that accrue shall only be paid in respect of the number of Shares earned in respect of a Performance-Based Award.


 






    -10-


     


    

 


		10.	EXERCISE OF OPTIONS AND ISSUE OF SHARES.



 


An Option (or any part or installment thereof) shall be exercised by
giving written notice (in a form acceptable to the Administrator which may include electronic notice) to the Company or its designee,
together with provision for payment of the aggregate exercise price in accordance with this Paragraph for the Shares as to which the Option
is being exercised, and upon compliance with any other condition(s) set forth in the Option Agreement. Such notice shall be signed
by the person exercising the Option, shall state the number of Shares with respect to which the Option is being exercised and shall contain
any representation required by the Plan or the Option Agreement. Payment of the exercise price for the Shares as to which such Option
is being exercised shall be made (a) in United States dollars in cash or by check, or (b) at the discretion of the Administrator,
through delivery of shares of Common Stock having a Fair Market Value equal as of the date of the exercise to the cash exercise price
of the Option and held for at least six months (if required to avoid negative accounting treatment), or (c) at the discretion of
the Administrator, by having the Company retain from the Shares otherwise issuable upon exercise of the Option, a number of shares having
a Fair Market Value equal as of the date of exercise to the aggregate exercise price of the number of Shares being exercised, or (d) at
the discretion of the Administrator, in accordance with a cashless exercise program established with a securities brokerage firm, and
approved by the Administrator, or (e) at the discretion of the Administrator, by any combination of (a), (b), (c) and (d) above
or (f) at the discretion of the Administrator, payment of such other lawful consideration as the Administrator may determine. Notwithstanding
the foregoing, the Administrator shall accept only such payment on exercise of an ISO as is permitted by Section 422 of the Code.


  


The Company shall then reasonably promptly deliver the Shares as to
which such Option was exercised to the Participant (or to the Participant’s Survivors, as the case may be). In determining what
constitutes “reasonably promptly,” it is expressly understood that the issuance and delivery of the Shares may be delayed
by the Company in order to comply with any law or regulation (including, without limitation, state securities or “blue sky”
laws) which requires the Company to take any action with respect to the Shares prior to their issuance. The Shares shall, upon delivery,
be fully paid, non-assessable Shares.


 


The Administrator shall have the right to accelerate the date of exercise
of any installment of any Option; provided that the Administrator shall not accelerate the exercise date of any installment of any
Option granted to an Employee as an ISO (and not previously converted into a Non-Qualified Option pursuant to Paragraph 28) without the
prior approval of the Employee, if such acceleration would violate the annual vesting limitation contained in Section 422(d) of
the Code, as described in Paragraph 6(b)(iv).


 


The Administrator may, in its discretion, amend any term or condition
of an outstanding Option provided (i) such term or condition as amended is not prohibited by the Plan, (ii) any such amendment
shall be made only with the consent of the Participant to whom the Option was granted, or in the event of the death of the Participant,
the Participant’s Survivors, if the amendment is adverse to the Participant, and (iii) any such amendment of any Option shall
be made only after the Administrator determines whether such amendment would constitute a “modification” of any Option which
is an ISO (as that term is defined in Section 424(h) of the Code) or would cause any adverse tax consequences for the holder
of such Option including, but not limited to, pursuant to Section 409A of the Code.


 






    -11-


     


    

 


		11.	ACCEPTANCE OF STOCK GRANTS AND STOCK-BASED AWARDS AND ISSUE OF SHARES.



  


A Stock Grant or Stock-Based Award (or any part or installment thereof)
shall be accepted by executing the applicable Agreement and delivering it to the Company or its designee, together with provision for
payment of the full purchase price, if any, in accordance with this Paragraph for the Shares as to which such Stock Grant or Stock-Based
Award is being accepted, and upon compliance with any other conditions set forth in the applicable Agreement. Payment of the purchase
price for the Shares as to which such Stock Grant or Stock-Based Award is being accepted shall be made (a) in United States dollars
in cash or by check, or (b) at the discretion of the Administrator, through delivery of shares of Common Stock held for at least
six months (if required to avoid negative accounting treatment) and having a Fair Market Value equal as of the date of acceptance of the
Stock Grant or Stock Based-Award to the purchase price of the Stock Grant or Stock-Based Award, or (c) at the discretion of the Administrator,
by any combination of (a) and (b) above; or (d) at the discretion of the Administrator, payment of such other lawful
consideration as the Administrator may determine.


 


The Company shall then, if required by the applicable Agreement, reasonably
promptly deliver the Shares as to which such Stock Grant or Stock-Based Award was accepted to the Participant (or to the Participant’s
Survivors, as the case may be), subject to any escrow provision set forth in the applicable Agreement. In determining what constitutes
 “reasonably promptly,” it is expressly understood that the issuance and delivery of the Shares may be delayed by the Company
in order to comply with any law or regulation (including, without limitation, state securities or “blue sky” laws) which requires
the Company to take any action with respect to the Shares prior to their issuance.


 


		12.	RIGHTS AS A SHAREHOLDER.



 


No Participant to whom a Stock Right has been granted shall have rights
as a shareholder with respect to any Shares covered by such Stock Right, except after due exercise of the Option or issuance of Shares
as set forth in any Agreement, and tender of the aggregate exercise or full purchase price, if any, for the Shares being purchased pursuant
to such exercise or acceptance and registration of the Shares in the Company’s share register in the name of the Participant.


 


		13.	ASSIGNABILITY AND TRANSFERABILITY OF STOCK RIGHTS.



 


By its terms, a Stock Right granted to a Participant shall not be transferable
by the Participant other than (i) by will or by the laws of descent and distribution, or (ii) as approved by the Administrator
in its discretion and set forth in the applicable Agreement; provided that no Stock Right may be transferred by a Participant for
value. Notwithstanding the foregoing, an ISO transferred except in compliance with clause (i) above shall no longer qualify as an
ISO. The designation of a beneficiary of a Stock Right by a Participant, with the prior approval of the Administrator and in such form
as the Administrator shall prescribe, shall not be deemed a transfer prohibited by this Paragraph. Except as provided above, a Stock Right
shall only be exercisable or may only be accepted, during the Participant’s lifetime, by such Participant (or by his or her legal
representative) and shall not be assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not
be subject to execution, attachment or similar process. Any attempted transfer, assignment, pledge, hypothecation or other disposition
of any Stock Right or of any rights granted thereunder contrary to the provisions of this Plan, or the levy of any attachment or similar
process upon a Stock Right, shall be null and void.

		14.	EFFECT ON OPTIONS OF TERMINATION OF SERVICE OTHER THAN FOR CAUSE OR DEATH OR DISABILITY.



 


Except as otherwise provided in a Participant’s Option Agreement,
in the event of a termination of service (whether as an Employee, director or Consultant) with the Company or an Affiliate before the
Participant has exercised an Option, the following rules apply:


 





		(a)	A Participant who ceases to be an Employee, director or Consultant of the Company or of an Affiliate (for any reason other than termination
for Cause, Disability, or death for which events there are special rules in Paragraphs 15, 16, and 17, respectively), may exercise
any Option granted to him or her to the extent that the Option is exercisable on the date of such termination of service, but only within
such term as the Administrator has designated in a Participant’s Option Agreement.



 


		(b)	Except as provided in Subparagraph (c) below, or Paragraph 16 or 17, in no event may an Option intended to be an ISO, be exercised
later than three months after the Participant’s termination of employment.



 


		(c)	The provisions of this Paragraph, and not the provisions of Paragraph 16 or 17, shall apply to a Participant who subsequently becomes
Disabled or dies after the termination of employment, director status or consultancy; provided, however, in the case of a Participant’s
Disability or death within three months after the termination of employment, director status or consultancy, the Participant or the Participant’s
Survivors may exercise the Option within one year after the date of the Participant’s termination of service, but in no event after
the date of expiration of the term of the Option.



 


		(d)	Notwithstanding anything herein to the contrary, if subsequent to a Participant’s termination of employment, termination of
director status or termination of consultancy, but prior to the exercise of an Option, the Administrator determines that, either prior
or subsequent to the Participant’s termination, the Participant engaged in conduct which would constitute Cause, then such Participant
shall forthwith cease to have any right to exercise any Option.



 


		(e)	A Participant to whom an Option has been granted under the Plan who is absent from the Company or an Affiliate because of temporary
disability (any disability other than a Disability as defined in Paragraph 1 hereof), or who is on leave of absence for any purpose, shall
not, during the period of any such absence, be deemed, by virtue of such absence alone, to have terminated such Participant’s employment,
director status or consultancy with the Company or with an Affiliate, except as the Administrator may otherwise expressly provide;
provided, however, that, for ISOs, any leave of absence granted by the Administrator of greater than ninety days, unless pursuant to a
contract or statute that guarantees the right to reemployment, shall cause such ISO to become a Non-Qualified Option on the 181st day
following such leave of absence.



 


		(f)	Except as required by law or as set forth in a Participant’s Option Agreement, Options granted under the Plan shall not be affected
by any change of a Participant’s status within or among the Company and any Affiliates, so long as the Participant continues to
be an Employee, director or Consultant of the Company or any Affiliate.



 






    -13-


     


    

 


		15.	EFFECT ON OPTIONS OF TERMINATION OF SERVICE FOR CAUSE.



 


Except as otherwise provided in a Participant’s Option Agreement,
the following rules apply if the Participant’s service (whether as an Employee, director or Consultant) with the Company or
an Affiliate is terminated for Cause prior to the time that all his or her outstanding Options have been exercised:


 


		(a)	All outstanding and unexercised Options as of the time the Participant is notified his or her service is terminated for Cause will
immediately be forfeited.



 


		(b)	Cause is not limited to events which have occurred prior to a Participant’s termination of service, nor is it necessary that
the Administrator’s finding of Cause occur prior to termination. If the Administrator determines, subsequent to a Participant’s
termination of service but prior to the exercise of an Option, that either prior or subsequent to the Participant’s termination
the Participant engaged in conduct which would constitute Cause, then the right to exercise any Option is forfeited.



 


		16.	EFFECT ON OPTIONS OF TERMINATION OF SERVICE FOR DISABILITY.



 


Except as otherwise provided in a Participant’s Option Agreement:


 


		(a)	A Participant who ceases to be an Employee, director or Consultant of the Company or of an Affiliate by reason of Disability may exercise
any Option granted to such Participant:



 


		(i)	To the extent that the Option has become exercisable but has not been exercised on the date of Disability; and






 





		(ii)	In the event rights to exercise the Option accrue periodically, to the extent of a pro rata portion through the date of Disability
of any additional vesting rights that would have accrued on the next vesting date had the Participant not become Disabled. The proration
shall be based upon the number of days accrued in the current vesting period prior to the date of Disability.



 






    -14-


     


    

 


		(b)	A Disabled Participant may exercise such rights only within the period ending one year after the date of the Participant’s Disability,
notwithstanding that the Participant might have been able to exercise the Option as to some or all of the Shares on a later date if the
Participant had not become Disabled and had continued to be an Employee, director or Consultant or, if earlier, within the originally
prescribed term of the Option.



 


		(c)	The Administrator shall make the determination both of whether Disability has occurred and the date of its occurrence (unless a procedure
for such determination is set forth in another agreement between the Company and such Participant, in which case such procedure shall
be used for such determination). If requested, the Participant shall be examined by a physician selected or approved by the Administrator,
the cost of which examination shall be paid for by the Company.



 


		17.	EFFECT ON OPTIONS OF DEATH WHILE AN EMPLOYEE, DIRECTOR OR CONSULTANT.



 


Except as otherwise provided in a Participant’s Option Agreement:


 


		(a)	In the event of the death of a Participant while the Participant is an Employee, director or Consultant of the Company or of an Affiliate,
such Option may be exercised by the Participant’s Survivors:



 


		(i)	To the extent that the Option has become exercisable but has not been exercised on the date of death; and



 


		(ii)	In the event rights to exercise the Option accrue periodically, to the extent of a pro rata portion through the date of death of any
additional vesting rights that would have accrued on the next vesting date had the Participant not died. The proration shall be based
upon the number of days accrued in the current vesting period prior to the Participant’s date of death.



 


		(b)	If the Participant’s Survivors wish to exercise the Option, they must take all necessary steps to exercise the Option within
one year after the date of death of such Participant, notwithstanding that the decedent might have been able to exercise the Option as
to some or all of the Shares on a later date if he or she had not died and had continued to be an Employee, director or Consultant or,
if earlier, within the originally prescribed term of the Option.



 


		18.	EFFECT OF TERMINATION OF SERVICE ON STOCK GRANTS AND STOCK-BASED AWARDS.



 


In the event of a termination of service (whether as an Employee, director
or Consultant) with the Company or an Affiliate for any reason before the Participant has accepted a Stock Grant or a Stock-Based Award
and paid the purchase price, if required, such offer shall terminate.


 


For purposes of this Paragraph 18 and Paragraph 19 below, a Participant
to whom a Stock Grant or a Stock-Based Award has been issued under the Plan who is absent from work with the Company or with an Affiliate
because of temporary disability (any disability other than a Disability as defined in Paragraph 1 hereof), or who is on leave of absence
for any purpose, shall not, during the period of any such absence, be deemed, by virtue of such absence alone, to have terminated such
Participant’s employment, director status or consultancy with the Company or with an Affiliate, except as the Administrator may
otherwise expressly provide.


 






    -15-


     


    

 


In addition, for purposes of this Paragraph 18 and Paragraph 19 below,
any change of employment or other service within or among the Company and any Affiliates shall not be treated as a termination of employment,
director status or consultancy so long as the Participant continues to be an Employee, director or Consultant of the Company or any Affiliate.


 


		19.	EFFECT ON STOCK GRANTS AND STOCK-BASED AWARDS OF TERMINATION OF SERVICE OTHER THAN FOR CAUSE OR DEATH OR DISABILITY.



 





Except as otherwise provided in a Participant’s Agreement, in
the event of a termination of service (whether as an Employee, director or Consultant), other than termination for Cause, Disability,
or death for which events there are special rules in Paragraphs 20, 21, and 22, respectively, before all forfeiture provisions or
Company rights of repurchase shall have lapsed, then the Company shall have the right to cancel or repurchase that number of Shares subject
to a Stock Grant or Stock-Based Award as to which the Company’s forfeiture or repurchase rights have not lapsed.


 


		20.	EFFECT ON STOCK GRANTS AND STOCK-BASED AWARDS OF TERMINATION OF SERVICE FOR CAUSE.



 


Except as otherwise provided in a Participant’s Agreement, the
following rules apply if the Participant’s service (whether as an Employee, director or Consultant) with the Company or an
Affiliate is terminated for Cause:


 


		(a)	All Shares subject to any Stock Grant or a Stock-Based Award that remain subject to forfeiture provisions or as to which the Company
shall have a repurchase right shall be immediately forfeited to the Company as of the time the Participant is notified his or her service
is terminated for Cause.



 


		(b)	Cause is not limited to events which have occurred prior to a Participant’s termination of service, nor is it necessary that
the Administrator’s finding of Cause occur prior to termination. If the Administrator determines, subsequent to a Participant’s
termination of service, that either prior or subsequent to the Participant’s termination the Participant engaged in conduct which
would constitute Cause, then all shares subject to any Stock Grant or Stock-Based Award that remained subject to forfeiture provisions
or as to which the Company had a repurchase right on the date of termination shall be immediately forfeited to the Company.



 


		21.	EFFECT ON STOCK GRANTS AND STOCK-BASED AWARDS OF TERMINATION OF SERVICE FOR DISABILITY.



 


Except as otherwise provided in a Participant’s Agreement, the
following rules apply if a Participant ceases to be an Employee, director or Consultant of the Company or of an Affiliate by reason
of Disability: to the extent the forfeiture provisions or the Company’s rights of repurchase have not lapsed on the date of Disability,
they shall be exercisable; provided, however, that in the event such forfeiture provisions or rights of repurchase lapse periodically,
such provisions or rights shall lapse to the extent of a pro rata portion of the Shares subject to such Stock Grant or Stock-Based Award
through the date of Disability as would have lapsed had the Participant not become Disabled. The proration shall be based upon the number
of days accrued prior to the date of Disability.


 






    -16-


     


    

 


The Administrator shall make the determination both of whether Disability
has occurred and the date of its occurrence (unless a procedure for such determination is set forth in another agreement between the Company
and such Participant, in which case such procedure shall be used for such determination). If requested, the Participant shall be examined
by a physician selected or approved by the Administrator, the cost of which examination shall be paid for by the Company.


 


		22.	EFFECT ON STOCK GRANTS AND STOCK-BASED AWARDS OF DEATH WHILE AN EMPLOYEE, DIRECTOR OR CONSULTANT.



 


Except as otherwise provided in a Participant’s Agreement, the
following rules apply in the event of the death of a Participant while the Participant is an Employee, director or Consultant of
the Company or of an Affiliate: to the extent the forfeiture provisions or the Company’s rights of repurchase have not lapsed on
the date of death, they shall be exercisable; provided, however, that in the event such forfeiture provisions or rights of repurchase
lapse periodically, such provisions or rights shall lapse to the extent of a pro rata portion of the Shares subject to such Stock Grant
or Stock-Based Award through the date of death as would have lapsed had the Participant not died. The proration shall be based upon the
number of days accrued prior to the Participant’s death.


 


		23.	PURCHASE FOR INVESTMENT.



 


Unless the offering and sale of the Shares to be issued upon the particular
exercise or acceptance of a Stock Right shall have been effectively registered under the Securities Act of 1933, as now in force or hereafter
amended (the “1933 Act”), the Company shall be under no obligation to issue the Shares covered by such exercise unless and
until the following conditions have been fulfilled:


 


		(a)	The person(s) who exercise(s) or accept(s) such Stock Right shall warrant to the Company, prior to the receipt of such
Shares, that such person(s) are acquiring such Shares for their own respective accounts, for investment, and not with a view to,
or for sale in connection with, the distribution of any such Shares, in which event the person(s) acquiring
such Shares shall be bound by the provisions of the following legend which shall be endorsed upon the certificate(s) evidencing their
Shares issued pursuant to such exercise or such grant:






 


“The shares represented by this certificate have been
taken for investment and they may not be sold or otherwise transferred by any person, including a pledgee, unless (1) either (a) a
Registration Statement with respect to such shares shall be effective under the Securities Act of 1933, as amended, or the Company shall
have received an opinion of counsel satisfactory to it that an exemption from registration under such Act is then available, and (2) there
shall have been compliance with all applicable state securities laws.”


 






    -17-


     


    

 


		(b)	At the discretion of the Administrator, the Company shall have received an opinion of its counsel that the Shares may be issued upon
such particular exercise or acceptance in compliance with the 1933 Act without registration thereunder.



 


		24.	DISSOLUTION OR LIQUIDATION OF THE COMPANY.



 


Upon the dissolution or liquidation of the Company, all Options granted
under this Plan which as of such date shall not have been exercised and all Stock Grants and Stock-Based Awards which have not been accepted,
to the extent required under the applicable Agreement, will terminate and become null and void; provided, however, that if the rights
of a Participant or a Participant’s Survivors have not otherwise terminated and expired, the Participant or the Participant’s
Survivors will have the right immediately prior to such dissolution or liquidation to exercise or accept any Stock Right to the extent
that the Stock Right is exercisable or subject to acceptance as of the date immediately prior to such dissolution or liquidation. Upon
the dissolution or liquidation of the Company, any outstanding Stock-Based Awards shall immediately terminate unless otherwise determined
by the Administrator or specifically provided in the applicable Agreement.


 


		25.	ADJUSTMENTS.



 


Upon the occurrence of any of the following events, a Participant’s
rights with respect to any Stock Right granted to him or her hereunder shall be adjusted as hereinafter provided, unless otherwise specifically
provided in a Participant’s Agreement:


 


		(a)	Stock Dividends and Stock Splits. If (i) the shares of Common Stock shall be subdivided or combined into a greater or
smaller number of shares or if the Company shall issue any shares of Common Stock as a stock dividend on its outstanding Common Stock,
or (ii) 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 Common Stock, each Stock Right and the number of shares of Common Stock deliverable thereunder shall be
appropriately increased or decreased proportionately, and appropriate adjustments shall be made, including in the exercise or purchase
price per share and Performance Goals applicable to outstanding Performance-Based Awards, to reflect such events. The number of Shares
subject to the limitations in Paragraph 3(a) and 4(c) shall also be proportionately adjusted upon the occurrence of such events.



 






    -18-


     


    

 


		(b)	Corporate Transactions. If the Company is to be consolidated with or acquired by another entity in a merger, consolidation,
or sale of all or substantially all of the Company’s assets or the acquisition of all of the outstanding voting stock of the Company
in a single transaction or a series of related transactions by a single entity other than a transaction to merely change the state of
incorporation (a “Corporate Transaction”), the Administrator or the board of directors of any entity assuming the obligations
of the Company hereunder (the “Successor Board”), shall, as to outstanding Options, either (i) make appropriate provision
for the continuation of such Options by substituting on an equitable basis for the Shares then subject to such Options either the consideration
payable with respect to the outstanding shares of Common Stock in connection with the Corporate Transaction or securities of any successor
or acquiring entity; or (ii) upon written notice to the Participants, provide that such Options must be exercised (either (A) to
the extent then exercisable, or (B) at the discretion of the Administrator, any such Options being made partially or fully exercisable
for purposes of this Subparagraph), within a specified number of days of the date of such notice, at the end of which period the Options
shall terminate; or (iii) terminate such Options in exchange for payment of an amount equal to the consideration payable upon
consummation of such Corporate Transaction to a holder of the number of shares of Common Stock into which such Option would have been
exercisable (either (A) to the extent then exercisable, or (B) at the discretion of the Administrator, any such Options being
made partially or fully exercisable for purposes of this Subparagraph) less the aggregate exercise price thereof. For purposes of determining
the payments to be made pursuant to Subclause (iii) above, in the case of a Corporate Transaction the consideration for
which, in whole or in part, is other than cash, the consideration other than cash shall be valued at the fair value thereof as determined
in good faith by the Board of Directors.






 


With respect to outstanding Stock Grants, the Administrator
or the Successor Board, shall either (i) make appropriate provisions for the continuation of such Stock Grants on the same terms
and conditions by substituting on an equitable basis for the Shares then subject to such Stock Grants either the consideration payable
with respect to the outstanding shares of Common Stock in connection with the Corporate Transaction or securities of any successor or
acquiring entity; or (ii) terminate all Stock Grants in exchange for payment of an amount equal to the consideration payable
upon consummation of such Corporate Transaction to the holder of the number of shares of Common Stock comprising such Stock Grant (to
the extent such Stock Grant is no longer subject to any forfeiture or repurchase rights then in effect or, at the discretion of the Administrator,
all forfeiture and repurchase rights being waived upon such Corporate Transaction).


 


In taking any of the actions permitted under this Paragraph
25(b), the Administrator shall not be obligated by the Plan to treat all Stock Rights, all Stock Rights held by a Participant, or all
Stock Rights of the same type, identically.


 


		(c)	Recapitalization or Reorganization. In the event of a recapitalization or reorganization of the Company other than a Corporate
Transaction pursuant to which securities of the Company or of another corporation are issued with respect to the outstanding shares of
Common Stock, a Participant upon exercising an Option or accepting a Stock Grant after the recapitalization or reorganization shall be
entitled to receive for the price paid upon such exercise or acceptance, if any, the number of replacement securities which would have
been received if such Option had been exercised or Stock Grant accepted prior to such recapitalization or reorganization.



 






    -19-


     


    

 


		(d)	Adjustments to Stock-Based Awards. Upon the happening of any of the events described in Subparagraphs a, b or c above, any
outstanding Stock- Based Award shall be appropriately adjusted to reflect the events described in such Subparagraphs. The Administrator
or the Successor Board shall determine the specific adjustments to be made under this Paragraph 25, including, but not limited to the
effect if any, of a Change of Control and, subject to Paragraph 4, its determination shall be conclusive.



 


		(e)	Modification of Options. Notwithstanding the foregoing, any adjustments made pursuant to Subparagraph a, b or c above with
respect to Options shall be made only after the Administrator determines whether such adjustments would constitute a “modification”
of any ISOs (as that term is defined in Section 424(h) of the Code) or would cause any adverse tax consequences for the holders
of such Options. If the Administrator determines that such adjustments made with respect to Options would constitute a modification or
other adverse tax consequence, it may refrain from making such adjustments, unless the holder of an Option specifically agrees in writing
that such adjustment be made and such writing indicates that the holder has full knowledge of the consequences of such “modification”
on his or her income tax treatment with respect to the Option. This paragraph shall not apply to the acceleration of the vesting of any
ISO that would cause any portion of the ISO to violate the annual vesting limitation contained in Section 422(d) of the Code,
as described in Paragraph 6(b)(iv).



 


		26.	ISSUANCES OF SECURITIES.



 


Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of shares subject to Stock Rights. Except as expressly provided herein, no adjustments
shall be made for dividends paid in cash or in property (including without limitation, securities) of the Company prior to any issuance
of Shares pursuant to a Stock Right.


 


		27.	FRACTIONAL SHARES.



 


No fractional shares shall be issued under the Plan and the person
exercising a Stock Right shall receive from the Company cash in lieu of such fractional shares equal to the Fair Market Value thereof.


 


		28.	CONVERSION OF ISOs INTO NON-QUALIFIED OPTIONS; TERMINATION OF ISOs.



 





The Administrator, at the written request of any Participant, may in
its discretion take such actions as may be necessary to convert such Participant’s ISOs (or any portions thereof) that have not
been exercised on the date of conversion into Non-Qualified Options at any time prior to the expiration of such ISOs, regardless of whether
the Participant is an Employee of the Company or an Affiliate at the time of such conversion. At the time of such conversion, the Administrator
(with the consent of the Participant) may impose such conditions on the exercise of the resulting Non-Qualified Options as the Administrator
in its discretion may determine, provided that such conditions shall not be inconsistent with this Plan. Nothing in the Plan shall be
deemed to give any Participant the right to have such Participant’s ISOs converted into Non-Qualified Options, and no such conversion
shall occur until and unless the Administrator takes appropriate action. The Administrator, with the consent of the Participant, may also
terminate any portion of any ISO that has not been exercised at the time of such conversion.


 






    -20-


     


    

 


		29.	WITHHOLDING.



 


In the event that any federal, state, or local income taxes, employment
taxes, Federal Insurance Contributions Act (“F.I.C.A.”) withholdings or other amounts are required by applicable law or governmental
regulation to be withheld from the Participant’s salary, wages or other remuneration in connection with the exercise or acceptance
of a Stock Right or upon the lapsing of any forfeiture provision or right of repurchase or for any other reason required by law, the Company
may withhold from the Participant’s compensation, if any, or may require that the Participant advance in cash to the Company, or
to any Affiliate of the Company which employs or employed the Participant, the statutory minimum amount of such withholdings unless a
different withholding arrangement, including the use of shares of the Company’s Common Stock is authorized by the Administrator
(and permitted by law). For purposes hereof, the fair market value of the shares withheld for purposes of payroll withholding shall be
determined in the manner set forth under the definition of Fair Market Value provided in Paragraph 1 above, as of the most recent practicable
date prior to the date of exercise. If the Fair Market Value of the shares withheld is less than the amount of payroll withholdings required,
the Participant may be required to advance the difference in cash to the Company or the Affiliate employer.


 


		30.	NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION.



 


Each Employee who receives an ISO must agree to notify the Company
in writing immediately after the Employee makes a Disqualifying Disposition of any shares acquired pursuant to the exercise of an ISO.
A Disqualifying Disposition is defined in Section 424(c) of the Code and includes any disposition (including any sale or gift)
of such shares before the later of (a) two years after the date the Employee was granted the ISO, or (b) one year after the
date the Employee acquired Shares by exercising the ISO, except as otherwise provided in Section 424(c) of the Code. If the
Employee has died before such stock is sold, these holding period requirements do not apply and no Disqualifying Disposition can occur
thereafter.


 


		31.	TERMINATION OF THE PLAN.



 


The Plan will terminate on March 28, 2028. The Plan may be terminated
at an earlier date by vote of the shareholders or the Board of Directors of the Company; provided, however, that any such earlier
termination shall not affect any Agreements executed prior to the effective date of such termination. Termination of the Plan shall not
affect any Stock Rights theretofore granted.


 






    -21-


     


    

 


		32.	AMENDMENT OF THE PLAN AND AGREEMENTS.



 


The Plan may be amended by the shareholders of the Company. The
Plan may also be amended by the Administrator, including, without limitation, to the extent necessary to qualify any or all
outstanding Stock Rights granted under the Plan or Stock Rights to be granted under the Plan for favorable federal income tax
treatment as may be afforded incentive stock options under Section 422 of the Code (including deferral of taxation upon
exercise), and to the extent necessary to qualify the shares issuable upon exercise or acceptance of any outstanding Stock Rights
granted, or Stock Rights to be granted, under the Plan for listing on any national securities exchange or quotation in any national
automated quotation system of securities dealers, provided that any amendment approved by the Administrator which the Administrator
determines is of a scope that requires shareholder approval shall also be subject to obtaining such shareholder approval. Other than
as set forth in Paragraph 25 of the Plan, the Administrator may not without shareholder approval reduce the exercise price of an
Option or cancel any outstanding Option in exchange for a replacement option having a lower exercise price, any Stock Grant, any
other Stock-Based Award or for cash. In addition, the Administrator may not take any other action that is considered a direct or
indirect “repricing” for purposes of the shareholder approval rules of the applicable securities exchange or
inter-dealer quotation system on which the Shares are listed, including any other action that is treated as a repricing under
generally accepted accounting principles. Any modification or amendment of the Plan shall not, without the consent of a Participant,
adversely affect his or her rights under a Stock Right previously granted to him or her, unless such amendment is required by
applicable law or necessary to preserve the economic value of such Stock Right. With the consent of the Participant affected, the
Administrator may amend outstanding Agreements in a manner which may be adverse to the Participant but which is not inconsistent
with the Plan. In the discretion of the Administrator, outstanding Agreements may be amended by the Administrator in a manner which
is not adverse to the Participant. Notwithstanding the foregoing, except in the case of death, disability or Change of Control,
outstanding Agreements may not be amended by the Administrator (or the Board) in a manner that would accelerate the exercisability
or vesting of, or lapsing of any right by the Company to restrict or reacquire Shares subject to, all or any portion of any Option,
Stock Grant or other Stock-Based Award. Nothing in this Paragraph 32 shall limit the Administrator’s authority to take any
action permitted pursuant to Paragraph 25.


 


		33.	EMPLOYMENT OR OTHER RELATIONSHIP.



 


Nothing in this Plan or any Agreement shall be deemed to prevent the
Company or an Affiliate from terminating the employment, consultancy or director status of a Participant, nor to prevent a Participant
from terminating his or her own employment, consultancy or director status or to give any Participant a right to be retained in employment
or other service by the Company or any Affiliate for any period of time.


 


		34.	CLAWBACK.



 


Notwithstanding anything to the contrary contained in this Plan, the
Company may recover from a Participant any compensation received from any Stock Right (whether or not settled) or cause a Participant
to forfeit any Stock Right (whether or not vested) in the event that the Company’s Incentive Compensation Recoupment Policy then
in effect is triggered.


 






    -22-


     


    

 


		35.	SECTION 409A.






 


If a Participant is a “specified employee” as defined in
Section 409A of the Code (and as applied according to procedures of the Company and its Affiliates) as of her or his separation from
service, to the extent any payment under this Plan or pursuant to the grant of a Stock-Based Award constitutes deferred compensation (after
taking into account any applicable exemptions from Section 409A of the Code), and to the extent required by Section 409A of
the Code, no payments due under this Plan or pursuant to a Stock-Based Award may be made until the earlier of: (i) the first day
of the seventh month following the Participant’s separation from service, or (ii) the Participant’s date of death;
provided, however, that any payments delayed during this six-month period shall be paid in the aggregate in a lump sum, without interest,
on the first day of the seventh month following the Participant’s separation from service.


 


The Administrator shall administer the Plan with a view toward ensuring
that Stock Rights under the Plan that are subject to Section 409A of the Code comply with the requirements thereof and that Options
under the Plan be exempt from the requirements of Section 409A of the Code, but neither the Administrator nor any member of the Board,
nor the Company nor any of its Affiliates, nor any other person acting hereunder on behalf of the Company, the Administrator or the Board
shall be liable to a Participant or any Survivor by reason of the acceleration of any income, or the imposition of any additional tax
or penalty, with respect to a Stock Right, whether by reason of a failure to satisfy the requirements of Section 409A of the Code
or otherwise.


 


		36.	GOVERNING LAW.



 


This Plan shall be construed and enforced in accordance with the law
of The Commonwealth of Massachusetts.
