HARVARD APPARATUS REGENERATIVE TECHNOLOGY,
INC.

EMPLOYEE STOCK PURCHASE PLAN

 

The purpose of the
Harvard Apparatus Regenerative Technology, Inc. Employee Stock Purchase Plan (“the Plan”) is to provide Eligible Employees
of Harvard Apparatus Regenerative Technology, Inc. (the “Company”) and any Designated Subsidiaries with opportunities
to purchase shares of the Company’s common stock, par value $.01 per share (the “Common Stock”). An aggregate
number of one hundred fifty thousand (150,000) shares of Common Stock have been approved and reserved under the Plan for this purpose.
The Plan is intended to constitute an “employee stock purchase plan” within the meaning of Section 423(b) of the Internal
Revenue Code of 1986, as amended (the “Code”), and shall be interpreted in accordance with that intent.

 

1.          ADMINISTRATION.
The Plan will be administered by the person or committee (the “Administrator”) appointed by the Company’s Board
of Directors (the “Board”) for such purpose. If the Administrator is a committee, its decisions shall be made by a
vote of the majority. The Administrator has authority to make rules and regulations for the administration and operation of the
Plan in accordance with the terms hereof, and its interpretations and decisions with regard thereto shall be final and conclusive.
No member of the Board or individual exercising administrative authority with respect to the Plan shall be liable for any action
or determination made in good faith with respect to the Plan or any Option granted hereunder.

 

2.          OFFERING
PERIODS. The Company will make one or more offerings to Eligible Employees to purchase Common Stock under the Plan in accordance
with this section. Unless otherwise determined by the Administrator, the initial Offering Period will begin on January 1, 2014
and will end on June 30, 2014 (the “Initial Offering”). Thereafter, unless otherwise determined by the Administrator,
an Offering Period will begin on the first business day occurring on or after each January 1 and July 1 and will end on the last
business day occurring on or before the next following June 30 and December 31, respectively. The Administrator may, in its discretion,
designate a different Offering Period, provided that no Offering Period shall exceed six months in duration or overlap any other
Offering Period.

 

3.          ELIGIBILITY.
Any employee of the Company (including employees who are also directors of the Company) and any employee of a Designated Subsidiary
is eligible to participate in any one or more Offering Periods under the Plan, provided that as of the first day of the applicable
Offering Period each such employee is customarily employed by the Company or a Designated Subsidiary for more than 20 hours a week.

 

    	 

    	 

    

 

4.          PARTICIPATION.
Participation in the Plan is completely voluntary. Participation in any one or more of the Offerings under the Plan shall neither
limit, nor require, participation in any other Offering. An Eligible Employee may become a Participant and purchase stock during
any Offering Period by executing and submitting an enrollment form to the Plan Administrator or its designee at least 15 business
days before the Offering Date (or by such other deadline as the Administrator shall establish for such Offering Period). The form
shall (a) designate the whole percentage to be deducted from the Participant’s Compensation per pay period, (b) authorize
the purchase of Common Stock for such Participant during each Offering Period in accordance with the terms of the Plan, and (c)
specify the exact name or names in which shares of Common Stock purchased for such Participant are to be issued pursuant to Section
10 hereof. An Eligible Employee who does not enroll in accordance with these procedures by the applicable deadline for an Offering
Period will be deemed to have waived his or her right to participate in the Plan during that Offering Period. Except as otherwise
provided in Section 6 hereof, unless an Eligible Employee files a new enrollment form or withdraws from the Plan, his or her prior
elections of payroll deductions and stock purchases will continue in effect for future Offering Periods, provided he or she remains
an Eligible Employee.

 

5.          PARTICIPANT
CONTRIBUTIONS AND NON-INTEREST BEARING PLAN ACCOUNTS. Each Participant may authorize payroll deductions at a minimum of one
percent (1%) up to a maximum of ten percent (10%) of his or her Compensation for each pay period. The Company shall maintain unfunded
book accounts for each Participant showing the amount of payroll deductions made by such Participant during each Offering Period.
All payroll deductions received or held by the Company under this Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions. No interest will accrue or be paid on payroll deductions
or Plan account balances.

 

6.          DEDUCTION
CHANGES. Except as may be permitted by the Administrator in advance of an Offering Period, a Participant may not increase or
decrease his or her payroll deduction during any Offering Period, but may increase or decrease his or her payroll deduction for
the next Offering Period (subject to the limitations of Section 5) by filing a new enrollment form at least 15 business days before
the next Offering Date (or by such other deadline as the Administrator shall establish for such Offering Period). The Administrator
may, in advance of any Offering Period, establish rules permitting a Participant to increase, decrease or terminate his or her
payroll deduction during an Offering Period.

 

7.          WITHDRAWAL.
A Participant may withdraw from participation in the Plan by delivering a written notice of withdrawal to the Plan Administrator
or to such Participant’s designated payroll personnel. The Participant’s withdrawal shall be effective as of the next
business day following delivery of such withdrawal notice. Following a Participant’s withdrawal from the Plan, the Company
(or Designated Subsidiary) shall promptly refund to such Participant such Participant’s entire account balance under the
Plan (after payment for any Common Stock purchased before the effective date of withdrawal). Partial withdrawals from a Participant’s
Plan account shall not be permitted. The Participant, having withdrawn from an Offering Period, may not begin participation again
during the remainder of such Offering Period, but may enroll in a subsequent Offering Period in accordance with Section 4. Notwithstanding
anything herein to the contrary, unless a Participant withdraws from the Plan as described in this Section, such Participant and
his or her elections shall continue to apply for future Offering Periods in accordance with the terms and conditions of the Plan.

 

    	2

    	 

    

 

8.          GRANT
OF OPTIONS. On each Offering Date, the Company will grant to each Plan Participant an option (“Option”) to purchase
on the Exercise Date at the Option Price (defined below) the lesser of (a) a number of whole shares of Common Stock, which number
shall not exceed the result of dividing $12,500 by the Option Price per share of Common Stock on the Offering Date, or (b) such
other maximum number of shares as shall have been established by the Administrator in advance of the Offering. The term “Option
Price” means 85% of the Fair Market Value of the Common Stock on the Offering Date or the Exercise Date, whichever is less.

 

Notwithstanding the
foregoing, no Participant may be granted an Option to purchase Common Stock hereunder if such Participant would be treated as owning
stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or
any Parent or Subsidiary thereof immediately after such Option would have been granted. For purposes of the preceding sentence,
the attribution rules of Section 424(d) of the Code shall apply in determining the stock ownership of a Participant, and all stock
which the Participant has a contractual right to purchase shall be treated as stock owned by such Participant. In addition, no
Participant may be granted an option to purchase stock hereunder or under any other employee stock purchase plan of the Company
and its Parents and Subsidiaries, that accrues at a rate which exceeds $25,000 of the Fair Market Value of such stock (determined
on any Offering Dates) for each calendar year in which such option is outstanding at any time. The purpose of the limitation in
the preceding sentence is to comply with Section 423(b)(8) of the Code.

 

9.          EXERCISE
OF OPTION AND PURCHASE OF SHARES. Each Eligible Employee who is or continues to be a Participant on an Exercise Date shall
be deemed to have exercised an Option automatically on such Exercise Date and shall acquire from the Company such number of whole
shares of Common Stock available under the Plan as the cash balance of such Participant’s accumulated payroll deduction account
on such Exercise Date can purchase at the Option Price, subject to any other limitations contained in the Plan. Any cash amount
remaining in such Participant’s account at the end of an Offering Period due solely to the inability to purchase a fractional
share shall be carried forward to the next Offering Period; however, any other cash balance remaining in an Participant’s
Plan account at the end of an Offering Period due to the imposition of other limits imposed by the Plan (including without limitation,
Section 8 hereof) will be refunded to the Participant promptly.

 

10.         ISSUANCE
OF CERTIFICATES. Certificates representing shares of Common Stock purchased under the Plan may be issued only in the name of
the Participant, in the name of the Participant and another person of legal age as joint tenants with rights of survivorship, or
in the name of a broker authorized by the Participant to be his, her or their, nominee for such purpose. No fractional shares of
Common Stock will be issued under the Plan.

 

11.         DEFINITIONS.

 

The term “Compensation”
means the amount of the Participant’s base pay from the Company (or applicable Designated Subsidiary) prior to any reduction
for deferrals pursuant to either Section 125 or 401(k) of the Code, including commissions, but excluding overtime,
incentive or bonus awards, allowances and reimbursements for expenses such as relocation allowances or travel expenses, income
or gains on the exercise of Company stock options, and similar extraordinary items.

 

    	3

    	 

    

 

The term “Designated
Subsidiary” means any present or future Subsidiary (as defined below) that has been designated by the Board to participate
in the Plan. The Board may so designate any Subsidiary, or revoke any such designation, at any time and from time to time, either
before or after the Plan is approved by the stockholders.

 

The term “Effective
Date” shall have the same meaning as that set forth under Section 26 hereof.

 

The term “Eligible
Employee” means any common law employee or director of the Company or a Designated Subsidiary who, on an Offering Date
meets the requirements described in Section 3 hereof.

 

The term “Exercise
Date” shall mean the last day of the Offering Period described in Section 2 hereof or on the last business day occurring
on or before June 30 or December 31.

 

The term “Fair
Market Value “ on any given date means the fair market value of the Common Stock determined in good faith by the Administrator;
PROVIDED, HOWEVER, that if the Common Stock is admitted to quotation on the Nasdaq
Global Market, Nasdaq Capital Market, New York Stock Exchange or other national securities exchange, the Fair Market Value
will equal the closing sales price as reported on such exchange on such date. If there are no market quotations for such date,
the determination shall be made by reference to the last date preceding such date for which there are market quotations.

 

The term “Offering
Period” shall have the same meaning as that set forth in section 2 hereof and shall generally refer to a period beginning
on January 1 or July 1 and ending on the last business day occurring on or before the next following June 30 or December 31.

 

The term “Offering
Date”, which shall also refer to a date of grant, shall mean the Effective Date or the first day of the Offering Period
described in Section 3 hereof or on the last business day occurring on or before January 1 or July 1.

 

The term “Option”
shall have the same meaning as that set forth under Section 8 hereof.

means an Eligible Employee who participates in the Plan and executes and submits the enrollment form described in Section 4 hereof.

    	4

    	 

    

 

12.         RIGHTS
ON TERMINATION OF EMPLOYMENT. An individual’s right to participate in the Plan shall terminate on such individual’s
termination employment for any reason or upon the date on which such individual is no longer an Eligible Employee. If a Participant’s
employment with an employer sponsoring the Plan terminates for any reason before the Exercise Date for any Offering Period, no
payroll deduction will be taken from such Participant’s Compensation, and the balance in his or her Plan account will be
paid to him or her except that in the case of such Participant’s death, such balance shall be paid to his or her designated
beneficiary as if such Participant had withdrawn from the Plan under Section 7. An Eligible Employee will be deemed to have terminated
employment, for this purpose, if the corporation that employs him or her, having been a Designated Subsidiary, ceases to be a Subsidiary,
or if such Employee is transferred to any corporation other than the Company or a Designated Subsidiary.

 

13.         SPECIAL
RULES. Notwithstanding anything herein to the contrary, the Administrator may adopt special rules applicable to the employees
of a particular Designated Subsidiary, whenever the Administrator determines that such rules are necessary or appropriate for the
implementation of the Plan in a jurisdiction where such Designated Subsidiary has employees; provided that such rules are consistent
with the requirements of Section 423(b) of the Code. Such special rules may include (by way of example, but not by way of limitation)
the establishment of a method for employees of a given Designated Subsidiary to fund the purchase of shares other than by payroll
deduction, if the payroll deduction method is prohibited by local law or is otherwise impracticable. Any special rules established
pursuant to this Section 13 shall, to the extent possible, result in the employees subject to such rules having substantially the
same rights as other participants in the Plan.

 

14.         OPTIONEES
NOT STOCKHOLDERS. Neither the granting of an Option hereunder to a Participant nor the deductions from such Participant’s
pay shall render such Participant a holder of the shares of Common Stock covered by an Option under the Plan until such shares
have been purchased by, or on behalf of, and issued to such Participant.

 

15.         RIGHTS
NOT TRANSFERABLE. Rights under the Plan are not transferable by a Participant other than by will or the laws of descent and
distribution, and are exercisable during the Participant’s lifetime only by such Participant.

 

16.         APPLICATION
OF FUNDS. All funds received or held by the Company under the Plan may be combined with other corporate funds and may be used
for any corporate purpose, and this Plan shall be deemed an unfunded arrangement.

 

17.         ADJUSTMENT
IN CASE OF CHANGES AFFECTING COMMON STOCK. In the event of an adjustment of the number of outstanding shares of Common Stock,
or the payment of a dividend in Common Stock, the number of shares approved for the Plan, and the share limitation set forth in
Section 8, shall be increased or decreased proportionately, and such other adjustments shall be made as may be deemed equitable
by the Administrator. In the event of any other change affecting the Common Stock, such adjustment shall be made as may be deemed
equitable by the Administrator to give proper effect to such event.

 

18.         AMENDMENT
OF THE PLAN. The Board may at any time, and from time to time, amend the Plan in any respect, provided that no amendment shall
be made increasing the number of shares approved for the Plan or making any other change that would require stockholder approval
in accordance with applicable laws, without the approval of the stockholders within 12 months of such Board action, in accordance
with the requirements of employee stock purchase plans under Section 423(b) of the Code.

 

    	5

    	 

    

 

19.         INSUFFICIENT
SHARES. If the sum of (a) total number of shares of Common Stock that would otherwise be purchased by Participants on any Exercise
Date, plus (b) the total number of such shares previously purchased by Participants exceeds the maximum number of shares reserved
under the Plan, the remaining reserved shares then available for issuance under the Plan shall be allocated proportionately to
Participants based on each Participant’s share of the aggregate amount of payroll deductions by all Participants who would
otherwise purchase Common Stock on such Exercise Date.

 

20.         TERMINATION
OF THE PLAN. The Plan may be terminated at any time by a vote of the Board. Upon termination of the Plan, all cash amounts
and stock in the accounts of Participants shall be promptly refunded.

 

21.         GOVERNMENTAL
REGULATIONS AND CHOICE OF LAW. The Company’s obligation to sell and deliver Common Stock under the Plan is subject to
obtaining all governmental approvals required in connection with the authorization, issuance, or sale of such stock.

 

The Plan shall be governed
by, and construed and enforced in accordance with, the provisions of Sections 423 and 424 of the Code and the substantive laws
of the State of Delaware (except to the extent that such laws are preempted by federal law). In the event of any inconsistency
between such provisions of the Code and any such laws, said provisions of the Code shall govern to the extent necessary to preserve
favorable federal income tax treatment afforded employee stock purchase plans under Section 423 of the Code.

 

22.         ISSUANCE
OF SHARES. Shares may be issued upon exercise of an Option from authorized but unissued Common Stock, from shares held in the
treasury of the Company, or from any other proper source.

 

23.         TAX
WITHHOLDING. Participation in the Plan is subject to any minimum required tax withholding on the Participant’s compensation
from the Company. The Company and its Subsidiaries shall have the undivided right to deduct any withholding taxes required by law
from any payment of any kind otherwise due to a Participant, including shares issuable under the Plan.

 

24.         NOTIFICATION
UPON SALE OF SHARES. Each Participant shall give the Company prompt notice of any disposition of such Participant’s shares
purchased under the Plan where such disposition occurs within two (2) years after the date of grant of the Option pursuant to which
such shares were purchased.

  

    	6

    	 

    

 

25.         EFFECTIVE
DATE AND APPROVAL OF SHAREHOLDERS. The Plan shall take effect on the date that Harvard Bioscience, Inc. no longer beneficially
owns at least 50% of the total voting power of the Company’s outstanding capital stock or such other date as the Board shall
establish (the “Effective Date”), subject to approval by the holders of a majority of the votes cast at a meeting of
stockholders at which a quorum is present, or by written consent of the stockholders, provided that any necessary governmental
approvals or qualifications of the purchase rights of the shares hereunder are obtained.

Pursuant to the Harvard Apparatus Regenerative Technology, Inc.
2013 Equity Incentive Plan, as amended through the date hereof (the “Plan”), Harvard Apparatus Regenerative Technology,
Inc., (the “Company”), hereby grants to the Optionee named above, an option (the “Option”) to purchase
on or prior to the Expiration Date specified above, all or part of the number of shares of Common Stock, par value $.01 per share
(the “Stock” or the “Shares”) 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 Option is intended to be an Incentive Stock Option
granted under the Plan.

 

1.        Vesting Schedule. No portion of
this Option may be exercised until such portion shall have vested. Except as set forth below and subject to the terms and conditions
set forth below, this Option shall be vested and exercisable with respect to the following number of Shares on the dates indicated:

 

	Cumulative	 	 
	Number of	 	 
	Shares Exercisable	 	Vesting Date
	 	 	 
	__________	 	__________
	 	 	 
	__________	 	__________
	 	 	 
	__________	 	__________
	 	 	 
	__________	 	__________

 

Once vested, this 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. The Optionee
may exercise the Option only in the following manner: from time to time on or prior to the Expiration Date, the Optionee may give
written notice to the Company of any election to purchase some or all of the vested Shares purchasable at the time of such notice.
Said notice shall specify the number of vested Shares to be purchased and shall be accompanied by payment therefor by one or more
of the following methods:

 

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

 

(2) 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 have been beneficially owned by the Optionee for at least six months and are not then subject to restrictions under any Company
plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date; or

 

    	1

    	 

    

 

(3) 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 Administrator shall prescribe as a condition of such payment
procedure.

 

Payment instruments will be received subject
to collection. The delivery of certificates representing the Shares will be contingent upon the Company’s receipt from the
Optionee of full payment for the Shares, as set forth above and 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 Options under the Plan and any
subsequent resale of the shares of Stock will be in compliance with applicable laws and regulations.

 

Certificates for the shares of Stock purchased
upon exercise of this Option shall be issued and delivered to the Optionee upon compliance, to the satisfaction of the Administrator,
with all requirements under applicable laws or regulations in connection with such issuance 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 Option unless and until this Option shall have been exercised pursuant to the terms hereof, the Company shall have issued
and delivered 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.

 

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

 

3.      Termination of Employment or Death
of Optionee. The Option, as to any Shares not theretofore purchased, shall terminate on the earlier of the Expiration Date
or 30 days after the Optionee is no longer employed by the Company or a Subsidiary (as defined in the Plan); provided, however,
that if such termination of employment results from (i) the Optionee’s death or disability, the Option may be exercised as
to vested Shares as of the date of such termination of employment within three (3) months thereafter (but in no event later than
the Expiration Date) by the Optionee’s executors, administrators, personal representatives, or any person or persons to whom
the Option may be transferred by will or by the laws of descent and distribution, but only to the extent that the Optionee was
entitled to exercise the Option at the time of such termination of Optionee’s employment or (ii) the Optionee’s termination
for Cause (as defined below), the Option (as to all vested and unvested Shares) shall immediately terminate and be of no further
force or effect. Following the termination of the Optionee’s employment and prior to the termination of the Option, unless
otherwise determined by the Administrator, the Option may only be exercised as to vested Shares as of the date of the termination
of the Optionee’s employment. The Option does not confer upon the Optionee any right with respect to continuation of employment
by the Company, nor shall it interfere with any right of the Company to terminate such employment at any time or any employee’s
“employee-at-will” status.

 

“Cause” as such term
relates to the termination of any person means the occurrence of one or more of the following: (i) such person is convicted of,
pleads guilty to, or confesses to any felony or any act of fraud, misappropriation or embezzlement, (ii) such person engages in
a fraudulent act to the material damage or prejudice of the Company or any Subsidiary or in conduct or activities materially damaging
to the property, business or reputation of the Company or any Subsidiary, (iii) any material act or omission by such person involving
malfeasance or negligence in the performance of such person’s duties to the Company or any Subsidiary to the material detriment
of the Company or any Subsidiary, which has not been corrected by such person within 30 days after written notice from the Company
of any such act or omission, (iv) failure by such person to comply in any material respect with the terms of his employment agreement,
if any, or any written policies or directives of the Board, which has not been corrected by such person within 30 days after written
notice from the Company of such failure, or (v) material breach by such person of his noncompetition agreement with the Company,
if any.

 

    	2

    	 

    

 

4.       Shares. The Shares that are the
subject of the Option are shares of the Common Stock, $.01 par value, of the Company as constituted on the date of the Option,
subject to adjustment as provided in Section 3 of the Plan.

 

5.       Effect of Certain Transactions.
If (i) the Company is merged into or consolidated with another corporation and the Company is not the surviving corporation, (ii)
one or more corporations are merged into the Company which continues as the surviving corporation and the stockholders of the Company
immediately prior to the transaction own less than a majority of its outstanding Common Stock immediately after the transaction,
or shares of Common Stock of the Company are converted into cash, securities or property other than shares of Common Stock of the
Company, or (iii) the Company is liquidated, dissolved, or sells or otherwise disposes of all or substantially all of its assets
to another entity while any portion of the Option remains unexercised and unexpired, then in any of such transactions the Board
may, in its sole discretion, take one or more of the following actions:

 

(a)       The Compensation Committee of the Board
(the “Committee”) may cancel the Option as of the effective date of any such transaction, provided that notice of such
cancellation shall be given to the Optionee at least 15 days prior to the effective date of such transaction, and the Optionee
shall have the right to exercise so much of the Option as is exercisable during said 15-day period, including Options which become
exercisable due to acceleration of vesting, if any, by the Board;

 

(b)       The Committee may (i) cancel the Option
as to unvested Shares as of the effective date of the transaction and (ii) provide for the repurchase of unexercised Options as
to vested Shares as of the effective date of such transaction by the Company on the effective date of such transaction for the
same cash, securities or other property received with respect to each outstanding Share in the transaction by the stockholders
of the Company, less the exercise price of the Option;

 

(c)       The Committee may provide for the voluntary
exchange of the Option on the effective date of such transaction for an option or other rights granted by a successor corporation
on terms reasonably acceptable to the Optionee; or

 

(d)      The Committee may provide that after the
effective date of such transaction, the Optionee shall be entitled upon exercise of the Option as to any vested Shares to receive
in lieu of each Share purchasable under the Option the same cash, securities or other property received with respect each outstanding
Share in the transaction by the stockholders of the Company.

 

Upon the consummation of a Sale Event (as
defined in the Plan) or occurrence of a Change of Control (as defined in the Plan), in either case, following the grant date of
the Option, the Option shall become fully vested and exercisable with respect to all of the Shares as of the effective time of
the Sale Event or the occurrence of the Change of Control, respectively.

 

6.      Status of the Option. This 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 Option qualifies as such. The Optionee should
consult with his or her own tax advisors regarding the tax effects of this 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. To the extent any
portion of this 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 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 Option, he or she will so notify the Company within 30 days after such disposition.

 

7.      Transferability.  This Option
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 Option is exercisable, during the Optionee’s lifetime, only by the
Optionee, and thereafter, only by the Optionee’s legal representative or legatee.

 

    	3

    	 

    

 

8.      Miscellaneous. Notices hereunder
shall be mailed or delivered to the Company’s principal place of business, 84 October Hill Road, Holliston, MA 01746 and
shall be mailed or delivered to the Optionee at the address set forth below, or in either case at such other address as one party
may subsequently furnish to the other party in writing.

 

9.     Incorporation of Plan. Notwithstanding
anything herein to the contrary, this 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 the Plan. Capitalized terms in this Option shall have the meaning specified in the
