depends for the successful conduct of its business, to acquire a proprietary interest in the Company. It is anticipated that providing

to remain with the Company.

 

The

limitations for each Award and may include, without limitation, the term of an Award, the provisions applicable in the event the

	SECTION 3.	STOCK ISSUABLE UNDER THE PLAN; MERGERS AND OTHER
TRANSACTIONS; SUBSTITUTION

 

(a)          Stock
Issuable. The maximum number of Shares reserved and available for issuance under the Plan shall be 26,624,362
Shares, subject to adjustment as provided in Section 3(b) hereof. For purposes of this limitation, the shares of Stock
underlying any Awards that are forfeited, canceled, withheld 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), in each case shall be added back 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.

 

(b)         
Changes in Stock. Subject to Section 3(c) hereof, if, as a result of any reorganization, recapitalization, reclassification,
stock 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, or 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 Committee shall make an appropriate and equitable
or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, (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 Award, and (iv) the exercise price for each share subject to any then outstanding Stock Options under
the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options) as
to which such Stock Options remain exercisable. The adjustment by the Committee shall be final, binding and conclusive. No fractional
shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Committee in its discretion may make
a cash payment in lieu of fractional shares.

 

(c)         
Sale Events.

 

		(i)	Options.

 

(A)       
In the case of and subject to the consummation of a Sale Event, the Plan and all Options issued hereunder shall terminate upon
the effective time of any such Sale Event unless provision is made in connection with the Sale Event for the assumption or continuation
of Options theretofore granted by the successor entity, or the substitution of such Options with new Options of the successor
entity or parent thereof, with an equitable or proportionate adjustment as to the number and kind of shares and, if appropriate,
the per share exercise prices, as such parties shall agree (after taking into account any acceleration hereunder and/or pursuant
to the terms of any Award Agreement).

    7 

     

    

(B)
         In the event of the termination of the Plan and all Options issued hereunder pursuant to Section 3(c), each Holder of Options
shall be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Committee,
to exercise all such Options which are then exercisable or will become exercisable as of the effective time of the Sale Event;
provided, however, that the exercise of Options not exercisable prior to the Sale Event shall be subject to the consummation
of the Sale Event.

 

(C)
         Notwithstanding anything to the contrary in Section 3(c)(i)(A), in the event of a Sale Event, the Company shall have the right,
but not the obligation, to make or provide for a cash payment to the grantees holding Options in exchange for the cancellation
thereof, in an amount equal to the difference between (A) the value as determined by the Committee of the consideration payable
per share of Stock pursuant to the Sale Event (the “Sale Price”) times the number of shares of Stock subject to outstanding
Options (to the extent then vested exercisable, including by reason of acceleration in connection with such Sale Event, at prices
not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding vested Options.

 

(ii)        
Option Shares. Unless otherwise provided in an Award Agreement, in the case of and subject to the consummation of a Sale
Event, Option Shares shall be subject to the repurchase right set forth in Section 9(c)(i).

 

(iii)        Restricted
Stock and Restricted Stock Unit Awards.

 

(A)
         In the case of and subject to the consummation of a Sale Event, all Restricted Stock and Restricted Stock Unit Awards issued hereunder
shall be forfeited immediately prior to the effective time of any such Sale Event unless provision is made in connection with
the Sale Event for the assumption or continuation of such Awards by the successor entity, or the substitution of such Awards with
new Awards of the successor entity or parent thereof, with an equitable or proportionate adjustment as to the number and kind
of shares subject to such Awards as such parties shall agree (after taking into account any acceleration hereunder and/or pursuant
to the terms of any Award Agreement).

 

(B)
         In the event of the forfeiture of shares of Restricted Stock issued hereunder pursuant to Section 3(c)(iii)(A), such shares of
Restricted Stock shall be repurchased from the Holder thereof at a price per share equal to the lower of the original per share
purchase price paid by the recipient (subject to adjustment as provided in Section 3(b)) or the current Fair Market Value of such
shares, determined immediately prior to the effective time of the Sale Event.

 

(C)
         Notwithstanding anything to the contrary in Section 3(c)(iii)(A), in the event of a Sale Event, the Company shall have the right,
but not the obligation, to make or provide for a cash payment to the grantees holding Restricted Stock or Restricted Stock Unit
Awards in exchange for the cancellation thereof, in an amount equal to the Sale Price times the number of shares of Stock subject
to such Awards, to be paid at the time of such Sale Event or upon the later vesting of such Awards.

    8 

     

    

(iv)       
Unrestricted Stock Awards. Unless otherwise provided in an Award Agreement, any shares of Unrestricted Stock shall be treated
in a Sale Event the same as all other Shares then outstanding.

 

	SECTION 4.	ELIGIBILITY

 

Grantees
under the Plan will be such full or part-time officers and other employees, directors, Consultants and key persons (including
prospective employees, but conditioned on their employment) of the Company and any Subsidiary who are selected from time to time
by the Committee in its sole discretion; provided, however, that an Incentive Stock Option may be granted only to
a person who, at the time the Incentive Stock Option is granted, is an employee of the Company or any Subsidiary.

 

	SECTION 5.	STOCK OPTIONS

 

The
grant of a Stock Option is contingent on the grantee executing a Stock Option Award Agreement. The terms and conditions of each
such Stock Option Award Agreement shall be determined by the Committee, and such terms and conditions may differ among individual
Awards and grantees, all of whom must be eligible persons under Section 4 hereof.

 

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.

 

No
Incentive Stock Option shall be granted under the Plan after the date which is ten years from the date the Plan is approved by
the Board.

 

(a)         
Terms of Stock Options. The Committee in its discretion may grant Stock Options to eligible officers, employees, directors,
Consultants and key persons of the Company or any Subsidiary. Stock Options granted pursuant to this Section 5(a) 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 Committee shall deem desirable. If the Committee 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 Committee may establish.

 

(i)         
Exercise Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to Section 5(a) shall
be determined by the Committee at the time of grant but shall not be less than 100 percent of the Fair Market Value on the Grant
Date. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the option price of such Incentive Stock
Option shall not be less than 110 percent of the Fair Market Value on the Grant Date.

 

(ii)        
Option Term. The term of each Stock Option shall be fixed by the Committee, 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 Grant Date.

    9 

     

    

(iii)        
Exercisability; Rights of a Stockholder. Stock Options shall become exercisable and/or vested at such time or times, whether
or not in installments, as shall be determined by the Committee at or after the Grant Date. The Award Agreement may permit an
optionee to exercise all or a portion of a Stock Option immediately at grant; provided that the Option Shares issued upon such
exercise shall be subject to restrictions and a vesting schedule identical to the vesting schedule of the related Stock Option
and the optionee shall be required to enter into a Restricted Stock Award Agreement and any other similar documentation required
by the Company as a condition to exercise of such 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. An optionee shall not be deemed to
have acquired any such shares unless and until a Stock Option shall have been exercised pursuant to the terms hereof and the optionee’s
name shall have been entered on the books of the Company as a stockholder.

 

(iv)        
Method of Exercise. Stock Options may be exercised by an optionee in whole or in part, by the optionee giving written 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 (or any combination thereof) to the extent provided in the Option Award Agreement:

 

(A)       
In cash, by certified or bank check, by wire transfer of immediately available funds, or other instrument acceptable to the Committee;

 

(B)
         If permitted by the Committee, by the optionee delivering to the Company a promissory note, if the Board has expressly authorized
the loan of funds to the optionee for the purpose of enabling or assisting the optionee to effect the exercise of his or her Stock
Option; provided, that at least so much of the exercise price as represents the par value of the Stock shall be paid other
than with a promissory note if required by state law;

 

(C)
         If permitted by the Committee and the Initial Public Offering has occurred (or the Stock otherwise becomes publicly-traded), 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 restrictions under any Company plan. To the extent
required to avoid variable accounting treatment under FASB ASC Topic 718 or other applicable accounting rules, such surrendered
shares if originally purchased from the Company shall have been owned by the optionee for at least six months. Such surrendered
shares shall be valued at Fair Market Value on the exercise date;

 

(D)       
If permitted by the Committee and the Initial Public Offering has occurred (or the Stock otherwise becomes publicly-traded), 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 Committee shall prescribe as a condition
of such payment procedure; and

    10 

     

    

(E)        
If permitted by the Committee, 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.

 

Payment
instruments will be received subject to collection. No certificates for shares of Stock so purchased will be issued to the optionee
or, with respect to uncertificated Stock, no transfer to the optionee on the records of the Company will take place, until the
Company has completed all steps required by law to be taken in connection with the issuance and sale of the shares, including
without limitation (i) receipt of a representation from the optionee at the time of exercise of the Option that the optionee is
purchasing the shares for the optionee’s own account and not with a view to any sale or distribution thereof, (ii) the legending
of any certificate (or notation on any book entry) representing the shares to evidence the foregoing restrictions, and (iii) obtaining
from optionee payment or provision for all withholding taxes due as a result of the exercise of the Option. The delivery of certificates
representing the shares of Stock (or the transfer to the optionee on the records of the Company with respect to uncertificated
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 or her 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 Option Award Agreement or applicable provisions of
laws. 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
shares attested to.

 

(b)         
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 the Plan and any other plan of the Company or its parent and any Subsidiary that
become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000 or such other limit as
may be in effect from time to time under Section 422 of the Code. To the extent that any Stock Option exceeds this limit, it shall
constitute a Non-Qualified Stock Option.

 

	SECTION 6.	RESTRICTED STOCK AWARDS

 

(a)         
Nature of Restricted Stock Awards. The Committee may, in its sole discretion, grant (or sell at par value or such higher
purchase price determined by the Committee) to an eligible person under Section 4 hereof a Restricted Stock Award under the Plan.
The Committee shall determine the restrictions and conditions applicable to each Restricted Stock Award at the time of grant.
Conditions may be based on continuing employment (or other Service Relationship), achievement of pre-established performance goals
and objectives and/or such other criteria as the Committee may determine. The grant of a Restricted Stock Award is contingent
on the grantee executing a Restricted Stock Award Agreement. The terms and conditions of each such Award Agreement shall be determined
by the Committee, and such terms and conditions may differ among individual Awards and grantees, all of whom must be eligible
persons under Section 4 hereof.

    11 

     

    

(b)         
Rights as a Stockholder. Upon execution of a Restricted Stock Award Agreement and payment of any applicable purchase price,
a grantee of Restricted Stock shall be considered the record owner of and shall be entitled to vote the Shares of Restricted Stock
if, and to the extent, such Shares are entitled to voting rights, subject to such conditions contained in the Restricted Stock
Award Agreement. The grantee shall be entitled to receive all dividends and any other distributions declared on the Shares; provided,
however, that the Company is under no duty to declare any such dividends or to make any such distribution. The Restricted
Stock Award Agreement may require or permit the immediate payment, waiver, deferral or investment of dividends paid on the Restricted
Stock. Unless the Committee shall otherwise determine, certificates evidencing the Restricted Stock shall remain in the possession
of the Company until such Restricted Stock is vested as provided in subsection (d) below of this Section, and the grantee shall
be required, as a condition of the grant, to deliver to the Company a stock power endorsed in blank and such other instruments
of transfer as the Committee may prescribe.

 

(c)         
Restrictions. Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except
as specifically provided herein or in the Restricted Stock Award Agreement. Except as may otherwise be provided by the Committee
either in the Award Agreement or, subject to Section 13 below, in writing after the Award Agreement is issued, if any, if a grantee’s
employment (or other Service Relationship) with the Company and any Subsidiary terminates, the Company or its assigns shall have
the right, as may be specified in the relevant instrument, to repurchase some or all of the Shares subject to the Award at such
purchase price as is set forth in the Restricted Stock Award Agreement.

 

(d)         
Vesting of Restricted Stock. The Committee 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 substantial risk of forfeiture imposed shall lapse
and the Restricted Stock shall become vested, subject to such further rights of the Company or its assigns as may be specified
in the Restricted Stock Award Agreement.

 

	SECTION 7.	UNRESTRICTED STOCK AWARDS

 

(a)         
Grant or Sale of Unrestricted Stock. The Committee may, in its sole discretion, grant (or sell at par value or such higher
purchase price determined by the Committee) to an eligible person under Section 4 hereof an Unrestricted Stock Award 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.

 

(b)         
Elections to Receive Unrestricted Stock In Lieu of Compensation. Upon the request of an eligible person under Section 4
hereof and with the consent of the Committee, each such grantee may, pursuant to an advance written election delivered to the
Company no later than the date specified by the Committee, receive a portion of any cash compensation otherwise due to such grantee
in the form of shares of Unrestricted Stock.

 

	SECTION 8.	RESTRICTED STOCK UNITS

 

(a)         
Nature of Restricted Stock Units. The Committee shall determine the restrictions and conditions applicable to each Restricted
Stock Unit at the time of grant. Vesting conditions may
be based on continuing employment (or other Service Relationship), achievement of pre-established performance goals and objectives
and/or other such criteria as the Committee may determine. The grant of Restricted Stock Unit(s) is contingent on the grantee
executing a Restricted Stock Unit Award Agreement. The terms and conditions of each such Award Agreement shall be determined by
the Committee and may differ among individual Awards and grantees. On or promptly following the vesting date or dates applicable
to any Restricted Stock Unit, such Restricted Stock Unit(s), shall be settled in the form of cash or shares of Stock, as specified
in the Award Agreement.

    12 

     

    

(b)         
Rights as a Stockholder. A grantee shall have the rights of a stockholder only as to shares of Stock, if any, acquired
upon settlement of a Restricted Stock Unit. A grantee shall not be deemed to have acquired any such shares unless and until a
Restricted Stock Unit shall have been settled in Stock pursuant to the terms hereof, the Company shall have issued and delivered
a certificate representing the shares to the grantee, and the grantee’s name shall have been entered in the books of the
Company as a stockholder.

 

(c)         
Termination. Except as may otherwise be provided by the Committee either in the Award Agreement or in writing after the
Award Agreement 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 any Subsidiary
for any reason.

 

	SECTION 9.	TRANSFER RESTRICTIONS; COMPANY RIGHT OF FIRST
REFUSAL; COMPANY REPURCHASE RIGHTS

 

(a)          Restrictions
on Transfer.

 

(i)         
Non-Transferability of Stock Options. No Stock Option shall be transferable by the optionee otherwise than by will or by
the laws of descent and distribution and all Stock Options shall be exercisable, during the optionee’s lifetime, only by
the optionee, or by the optionee’s legal representative or guardian in the event of the optionee’s incapacity. Notwithstanding
the foregoing, the Committee, in its sole discretion, may provide in the Award Agreement regarding a given Stock Option that the
optionee may transfer, without consideration for the transfer, his or her Non-Qualified Stock Options to members of his or her
immediate family, 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 Option.

    13 

     

    

(ii)        
Issued Shares. No Issued Shares shall be sold, assigned, transferred, pledged, hypothecated, given away or in any other
manner disposed of or encumbered, whether voluntarily or by operation of law, unless (i) such transfer is in compliance with the
terms of the applicable Award Agreement, all applicable securities laws (including, without limitation, the Securities Act), and
with the terms and conditions of this Section 9, (ii) such transfer does not cause the Company to become subject to the reporting
requirements of the Exchange Act, and (iii) the transferee consents in writing to be bound by the provisions of the Plan, including
this Section 9. In connection with any proposed transfer, the Committee may require the transferor to provide at the transferor’s
own expense an opinion of counsel to the transferor, satisfactory to the
Committee, that such transfer is in compliance with all foreign, federal and state securities laws (including, without limitation,
the Securities Act). Any attempted disposition of Issued Shares not in accordance with the terms and conditions of this Section
9 shall be null and void, and the Company shall not reflect on its records any change in record ownership of any Issued Shares
as a result of any such disposition, shall otherwise refuse to recognize any such disposition and shall not in any way give effect
to any such disposition of Issued Shares. Subject to the foregoing general provisions, and unless otherwise provided in the applicable
Award Agreement, Issued Shares may be transferred pursuant to the following specific terms and conditions (provided that with
respect to any transfer of Restricted Stock, all vesting and forfeiture provisions shall continue to apply only with respect to
the original recipient):

 

(A)       
Transfers to Permitted Transferees. The Holder may sell, assign, transfer or give away any or all of the Issued Shares
to Permitted Transferees; provided, however, that following such sale, assignment, or other transfer, such Issued Shares
shall continue to be subject to the terms of this Plan (including this Section 9) and such Permitted Transferee(s) shall, as a
condition to any such transfer, deliver a written acknowledgment to that effect to the Company.

 

(B)       
Transfers Upon Death. Upon the death of the Holder, any Issued Shares then held by the Holder at the time of such death
and any Issued Shares acquired thereafter by the Holder’s legal representative shall be subject to the provisions of this
Plan, and the Holder’s estate, executors, administrators, personal representatives, heirs, legatees and distributees shall
be obligated to convey such Issued Shares to the Company or its assigns under the terms contemplated hereby.

 

(b)         
Right of First Refusal. In the event that a Holder desires at any time to sell or otherwise transfer all or any part of
such Holder’s Issued Shares (other than shares of Restricted Stock which by their terms are not transferrable), the Holder
first shall give written notice to the Company of the Holder’s intention to make such transfer. Such notice shall state
the number of Issued Shares which the Holder proposes to sell (the “Offered Shares”), the price and the terms at which
the proposed sale is to be made and the name and address of the proposed transferee. At any time within 30 days after the receipt
of such notice by the Company, the Company or its assigns may elect to purchase all or any portion of the Offered Shares at the
price and on the terms offered by the proposed transferee and specified in the notice. The Company or its assigns shall exercise
this right by mailing or delivering written notice to the Holder within the foregoing 30-day period. If the Company or its assigns
elect to exercise its purchase rights under this Section 9(b), the closing for such purchase shall, in any event, take place within
45 days after the receipt by the Company of the initial notice from the Holder. In the event that the Company or its assigns do
not elect to exercise such purchase right, or in the event that the Company or its assigns do not pay the full purchase price
within such 45-day period, the Holder may, within 60 days thereafter, sell the Offered Shares to the proposed transferee and at
the same price and on the same terms as specified in the Holder’s notice. Any Shares purchased by such proposed transferee
shall no longer be subject to the terms of the Plan. Any Shares not sold to the proposed transferee shall remain subject to the
Plan.

    14 

     

    

		(c)	Company’s
                                         Right of Repurchase.

 

(i)         
Right of Repurchase for Option Shares. The Company or its assigns shall have the right and option upon a Repurchase Event
to repurchase from a Holder of Option Shares some or all (as determined by the Company) of the Option Shares held or subsequently
acquired upon exercise of a Stock Option by such Holder at the price per share specified below. Such repurchase right may be exercised
by the Company within the later of (A) six months following the date of such Repurchase Event or (B) seven months after the acquisition
of such Option Shares upon exercise of a Stock Option (the “Option Shares Repurchase Period”). The “Option Shares
Repurchase Price” shall be equal to the Fair Market Value of the Option Shares, determined as of the date the Committee
elects to exercise its repurchase rights in connection with a Repurchase Event.

 

(ii)        
Right of Repurchase With Respect to Restricted Stock and Shares issued pursuant to an Unrestricted Stock Award or Restricted Stock
Unit Award. Unless otherwise set forth in the agreement entered into by the recipient and the Company in connection with a Restricted
Stock Award, Unrestricted Stock Award or Restricted Stock Unit Award, the Company or its assigns shall have the right and option
upon a Repurchase Event to repurchase from a Holder of Issued Shares received pursuant to a Restricted Stock Award, Unrestricted
Stock Award or Restricted Stock Unit Award some or all (as determined by the Company) of such Issued Shares at the price per share
specified below. In addition, upon a Termination Event, the Company or its assigns shall have the right and option to repurchase
from a Holder of Issued Shares received pursuant to a Restricted Stock Award any Issued Shares which have not vested as of the
Termination Event. Such repurchase right may be exercised by the Company within six months following the date of such Repurchase
Event or Termination Event as applicable (the “Non-Option Shares Repurchase Period”). The “Non-Option Shares
Repurchase Price” shall be (i) in the case of Issued Shares which are vested as of the date of the Repurchase Event, the
Fair Market Value of such Issued Shares as of the date the Company elects to exercise its repurchase rights in connection with
a Repurchase Event and (ii) in the case of Issued Shares which have not vested as of the date of the Repurchase Event or Termination
Event (as applicable), the lower of the original per share purchase price paid by the recipient subject to adjustment as provided
in Section 3(b) or the current Fair Market Value of such Issued Shares as of the date the Company elects to exercise its repurchase
rights in connection with a Repurchase Event or Termination Event (as applicable).

 

(iii)       
Procedure. Any repurchase right of the Company shall be exercised by the Company or its assigns by giving the Holder written
notice on or before the last day of the Option Shares Repurchase Period or Non-Option Shares Repurchase Period, as applicable,
of its intention to exercise such repurchase right. Upon such notification, the Holder shall promptly surrender to the Company,
free and clear of any liens or encumbrances, any certificates representing the Shares being purchased, together with a duly executed
stock power for the transfer of such Shares to the Company or the Company’s assignee or assignees. Upon the Company’s
or its assignee’s receipt of the certificates from the Holder, the Company or its assignee or assignees shall deliver to
him, her or them a check for the Option Shares Repurchase Price or the Non-Option Shares Repurchase Price, as applicable; provided,
however, that the Company may pay the Option Shares Repurchase Price or Non-Option Shares Repurchase Price, as applicable,
by offsetting and canceling any indebtedness then owed by the Holder to the Company.

    15 

     

    

(d)         
Drag Along Right. In the event the holders of a majority of the Company’s equity securities then outstanding (the
 “Majority Shareholders”) determine to enter into a Sale Event in a bona fide negotiated transaction (a “Sale”),
with any non-Affiliate of the Company or any majority shareholder (in each case, the “Buyer”), a Holder of Issued
Shares, including any Permitted Transferees, shall be obligated to and shall upon the written request of the Majority Shareholders:
(a) sell, transfer and deliver, or cause to be sold, transferred and delivered, to the Buyer, his or her Issued Shares (including
for this purpose all of such Holder’s or his or her Permitted Transferee’s Issued Shares that presently or as a result
of any such transaction may be acquired upon the exercise of an Option (following the payment of the exercise price therefor))
on substantially the same terms applicable to the Majority Shareholders (with appropriate adjustments to reflect the conversion
of convertible securities, the redemption of redeemable securities and the exercise of exercisable securities as well as the relative
preferences and priorities of preferred stock); and (b) execute and deliver such instruments of conveyance and transfer and take
such other action, including voting such Issued Shares in favor of any Sale proposed by the Majority Shareholders and executing
any purchase agreements, merger agreements, indemnity agreements, escrow agreements or related documents as the Majority Shareholders
or the Buyer may reasonably require in order to carry out the terms and provisions of this Section 9(d).

 

		(e)	Escrow
                                         Arrangement.

 

(i)         
Escrow. In order to carry out the provisions of Sections 9(b), (c), and (d) of this Agreement more effectively, the Company
shall hold any Issued Shares in escrow together with separate stock powers executed by the Holder in blank for transfer, and any
Permitted Transferee shall, as an additional condition to any transfer of Issued Shares, execute a like stock power as to such
Issued Shares. The Company shall not dispose of the Issued Shares except as otherwise provided in this Agreement. In the event
of any repurchase by the Company (or any of its assigns), the Company is hereby authorized by the Holder and any Permitted Transferee,
as the Holder’s and each such Permitted Transferee’s attorney-in-fact, to date and complete the stock powers necessary
for the transfer of the Issued Shares being purchased and to transfer such Issued Shares in accordance with the terms hereof.
At such time as any Issued Shares are no longer subject to the Company’s repurchase, first refusal and drag along rights,
the Company shall, at the written request of the Holder, deliver to the Holder (or the relevant Permitted Transferee) a certificate
representing such Issued Shares with the balance of the Issued Shares to be held in escrow pursuant to this Section 9(e).

 

(ii)        
Remedy. Without limitation of any other provision of this Agreement or other rights, in the event that a Holder, any Permitted
Transferees or any other Person is required to sell a Holder’s Issued Shares pursuant to the provisions of Sections 9(b),
(c), or (d) hereof and in the further event that he or she refuses or for any reason fails to deliver to the Company or its designated
purchaser of such Issued Shares the certificate or certificates evidencing such Issued Shares together with a related stock power,
the Company or such designated purchaser may deposit the applicable purchase price for such Issued Shares with a bank designated
by the Company, or with the Company’s independent public accounting firm, as agent or trustee, or in escrow, for such Holder,
any Permitted Transferees or other Person, to be held by such bank or accounting firm for the benefit of and for delivery to him,
her, them or it, and/or, in its discretion, pay such purchase price by offsetting any indebtedness then owed by such Holder as
provided above.
Upon any such deposit and/or offset by the Company or its designated purchaser of such amount and upon notice to the Person who
was required to sell the Issued Shares to be sold pursuant to the provisions of Sections 9(b), (c), or (d), such Issued Shares
shall at such time be deemed to have been sold, assigned, transferred and conveyed to such purchaser, such Holder shall have no
further rights thereto (other than the right to withdraw the payment thereof held in escrow, if applicable), and the Company shall
record such transfer in its stock transfer book or in any appropriate manner.

    16 

     

    

(f)          
Lockup Provision. A Holder agrees, if requested by the Company and any underwriter engaged by the Company, not to sell
or otherwise transfer or dispose of any Issued Shares (including, without limitation, pursuant to Rule 144 under the Securities
Act) held by him or her for such period following the effective date of any registration statement of the Company filed under
the Securities Act as the Company or such underwriter shall specify reasonably and in good faith.

 

(g)         
Adjustments for Changes in Capital Structure. If, as a result of any reorganization, recapitalization, reclassification,
stock dividend, stock split, reverse stock split or other similar change in the Common Stock, the outstanding shares of Common
Stock are increased or decreased or are exchanged for a different number or kind of shares of the Company’s Stock, the restrictions
contained in this Section 9 shall apply with equal force to additional and/or substitute securities, if any, received by Holder
in exchange for, or by virtue of his or her ownership of, Issued Shares.

 

(h)         
Termination. The terms and provisions of Section 9(b), Section 9(c) (except for the Company’s right to repurchase
unvested Restricted Stock Awards upon a Termination Event) and Section 9(d) shall terminate upon the closing of the Company’s
Initial Public Offering or upon consummation of any Sale Event, in either case as a result of which shares of the Company (or
a successor entity) of the same class as the Issued Shares are registered under Section 12 of the Exchange Act and publicly-traded
on NASDAQ or any national security exchange.

 

	SECTION 10.	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
amounts received thereunder first becomes includable in the gross income of the grantee for Federal income tax purposes, pay to
the Company, or make arrangements satisfactory to the Committee 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 any Subsidiary 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 stock certificates (or evidence of book entry) to any grantee is subject to and conditioned on any such
tax withholding obligations being satisfied by the grantee.

 

(b)         
Payment in Stock. Subject to approval by the Committee, a grantee may elect to have the Company’s required tax withholding
obligation satisfied, in whole or in part, by authorizing the Company to withhold 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 applicable withholding
amount due.

    17 

     

    

	SECTION 11.	SECTION 409A AWARDS.

 

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 Committee
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 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.

 

	SECTION 12.	TRANSFER, LEAVE OF ABSENCE, ETC.

 

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

 

(a)        
a transfer to the employment of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another;
or

 

(b)        
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 Committee otherwise so provides in writing.

 

	SECTION 13.	AMENDMENTS AND TERMINATION

 

The
Board may, at any time, amend or discontinue the Plan and the Committee may, at any time, amend or cancel any outstanding Award
(or provide substitute Awards at the same or a reduced exercise or purchase price or with no exercise or purchase price in a manner
not inconsistent with the terms of the Plan; provided, that such price, if any, must satisfy the requirements which would
apply to the substitute or amended Award if it were then initially granted under the Plan for the purpose of satisfying changes
in law or for any other lawful purpose), but no such action shall adversely affect rights under any outstanding Award without
the consent of the holder of the Award. The Committee may exercise its discretion to reduce the exercise price of outstanding
Stock Options or effect repricing through cancellation of outstanding Awards and by granting such holders new Awards in replacement
of the cancelled Awards. To the extent determined by the Committee to be required either by the Code to ensure that Incentive
Stock Options granted under the Plan are qualified under Section 422 of the Code or otherwise, Plan amendments shall be subject
to approval by the Company stockholders entitled to vote at a meeting of stockholders. Nothing in this Section 13 shall limit
the Board’s or Committee’s authority to take any action permitted pursuant to Section 3(c).

    18 

     

    

	SECTION 14.	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 Committee shall
otherwise expressly so determine in connection with any Award or Awards. In its sole discretion, the Committee 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 15.	GENERAL PROVISIONS

 

(a)         
No Distribution; Compliance with Legal Requirements. The Committee 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 of Stock without a view
to distribution thereof. No shares of Stock shall be issued pursuant to an Award until all applicable securities law and other
legal and stock exchange or similar requirements have been satisfied. The Committee may require the placing of such stop-orders
and restrictive legends on certificates for Stock and Awards as it deems appropriate.

 

(b)         
Delivery of Stock Certificates. Stock certificates to grantees under the 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).

 

(c)         
Other Compensation Arrangements; No Employment Rights. Nothing contained in the 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 the Plan and the grant of Awards do not confer upon any employee any right
to continued employment or Service Relationship with the Company or any Subsidiary.

 

(d)         
Trading Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to such Company’s
insider trading policy-related restrictions, terms and conditions as may be established by the Committee, or in accordance with
policies set by the Committee, from time to time.

 

(e)         
Designation of Beneficiary. Each grantee to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries
to exercise any Award on or after the grantee’s death 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 Committee and shall not be effective until received
by the Committee. 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.

    19 

     

    

(f)          
Legend. Any certificate(s) representing the Issued Shares shall carry substantially the following legend (and with respect
to uncertificated Stock, the book entries evidencing such shares shall contain the following notation):

 

The
transferability of this certificate and the shares of stock represented hereby are subject to the restrictions, terms and conditions
(including repurchase and restrictions against transfers) contained in the Rapid Micro Biosystems, Inc. 2010 Stock Option and
Grant Plan and any agreement entered into thereunder by and between the company and the holder of this certificate (a copy of
which is available at the offices of the company for examination).

 

	SECTION 16.	EFFECTIVE DATE OF PLAN

 

The
Plan shall become effective upon approval of stockholders in accordance with applicable state law, and the Company’s certificate
of incorporation and bylaws. Subject to such approval by the stockholders and to the requirement that no Stock Option or other
Award may be issued hereunder prior to such approval, Stock Options and other Awards may be granted hereunder on and after adoption
of the Plan by the Board. No grants of Stock Options and other Awards may be made hereunder after the tenth anniversary of the
Effective Date and no grants of Incentive Stock Options may be made hereunder after the tenth anniversary of the date the Plan
is approved by the Board.

 

	SECTION 17.	GOVERNING LAW

 

This
Plan, all Awards and any controversy arising out of or relating to this Plan and all Awards shall be governed by and construed
in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all
other matters shall be governed by and construed in accordance with the internal laws of the Commonwealth of Massachusetts, without
regard to conflict of law principles that would result in the application of any law other than the law of the Commonwealth of
Massachusetts.

and such shares once issued shall be referred to as the “Option Shares”), at the Option Exercise Price per share,
subject to the terms and conditions set forth in this Incentive Stock Option Agreement (this “Agreement”) and in
the Plan. This Stock Option is intended to qualify as an “incentive stock option” as defined in Section 422(b) of
the Internal Revenue Code of 1986, as amended from time to time (the “Code”). To the extent that any portion of
the Stock Option does not so qualify, it shall be deemed a non-qualified stock option.

 

All
capitalized terms used herein and not otherwise defined shall have the respective meanings set forth in the Plan.

 

1.
           Vesting, Exercisability and Termination.

 

(a)
       No portion of this Stock Option may be exercised until such portion shall have vested and
become exercisable.

 

(b)
       Subject to the determination of the Committee in its sole discretion to accelerate the vesting
schedule hereunder, this Stock Option shall become vested and exercisable as set forth in the Grant Summary. Notwithstanding anything
herein to the contrary in the case of a Sale Event, this Stock Option shall be treated as provided in Section 3(c) of the Plan.

    

     

    

(c)
          Termination. Except as may otherwise be provided by the Committee, if the Optionee’s
Service Relationship is terminated, the period within which to exercise this Stock Option will be subject to earlier termination
as set forth below (and if not exercised within such period, shall thereafter terminate subject, in each case to Section 3(c)
of the Plan):

 

(i)
        Termination Due to Death or Disability. If the Optionee’s Service Relationship
terminates by reason of such Optionee’s death or disability (as defined in Section 422(c) of the Code), this Stock
Option may be exercised, to the extent exercisable on the date of such termination, by the Optionee, the Optionee’s legal
representative or legatee for a period of 12 months from the date of death or disability or until the Expiration Date, if earlier.

 

(ii)
        Other Termination. If the Optionee’s Service Relationship terminates for
any reason other than death or disability (as defined in Section 422(c) of the Code), and unless otherwise determined by the Committee,
this Stock Option may be exercised, to the extent exercisable on the date of termination, for a period of 90 days from the date
of termination or until the Expiration Date or other termination date, if earlier; provided  however, if the
Optionee’s Service Relationship is terminated for Cause, this Stock Option shall terminate immediately upon the date of
such termination.

 

For
purposes hereof, the Committee’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. Any portion of this Stock Option that
is not exercisable on the date of termination of the Service Relationship shall terminate immediately and be null and void.

 

(d)
         It is understood and intended that this Stock Option is intended to qualify as an “incentive
stock option” as defined in Section 422 of the Code to the extent permitted under applicable law. Accordingly, the Optionee
understands that in order to obtain the benefits of an incentive stock option under Section 422 of the Code, no sale or other
disposition may be made of Option Shares for which incentive stock option treatment is desired within the one-year period beginning
on the day after the day of the transfer of such Option Shares to him or her, nor within the two-year period beginning on the
day after Grant Date of this Stock Option and further 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. If the
Optionee disposes (whether by sale, gift, transfer or otherwise) of any such Option Shares within either of these periods, he
or she will notify the Company within 30 days after such disposition. The Optionee also agrees to provide the Company with any
information concerning any such dispositions required by the Company for tax purposes. Further, to the extent the Underlying Shares
and any other incentive stock options of the Optionee having an aggregate Fair Market Value in excess of $100,000 (determined
as of the Grant Date) first become exercisable in any year, such options will not qualify as incentive stock options.

    2

     

    

2.
           Exercise of Stock Option.

 

(a)
       The Optionee may exercise this Stock Option only in the following manner: Prior to the
Expiration Date, the Optionee may deliver a Stock Option exercise notice (an “Exercise Notice”) in the form
of Appendix A hereto indicating his or her election to purchase some or all of the Underlying Shares with respect to
which this Stock Option is exercisable at the time of such notice. Such notice shall specify the number of Underlying Shares
to be purchased. Payment of the purchase price may be made by one or more of the methods described in Sections 5(a)(iv)(A),
(B), (C) or (D) of the Plan, subject to the limitations contained in such Sections of the Plan, including the requirement
that the Committee specifically approve in advance certain payment methods.

 

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

 

3.          
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.

 

4.
           Transferability of Stock Option. This Agreement is personal to the
Optionee and is not transferable by the Optionee in any manner other than by will or by the laws of descent and distribution.
The Stock Option may be exercised during the Optionee’s lifetime only by the Optionee (or by the Optionee’s guardian
or personal representative in the event of the Optionee’s incapacity). The Optionee may elect to designate a beneficiary
by providing written notice of the name of such beneficiary to the Company, and may revoke or change such designation at any time
by filing written notice of revocation or change with the Company; such beneficiary may exercise the Optionee’s Stock Option
in the event of the Optionee’s death to the extent provided herein. If the Optionee does not designate a beneficiary, or
if the designated beneficiary predeceases the Optionee, the legal representative of the Optionee may exercise this Stock Option
to the extent provided herein in the event of the Optionee’s death.

 

5.
           Restrictions on Transfer of Option Shares. The Option Shares acquired
upon exercise of the Stock Option shall be subject to certain transfer restrictions and other limitations including, without limitation,
the provisions contained in Section 9 of the Plan.

 

6.
           Miscellaneous Provisions.

 

(a)
       Equitable Relief. The parties hereto agree and declare that legal remedies may be inadequate
to enforce the provisions of this Agreement and that equitable relief, including specific performance and injunctive relief, may
be used to enforce the provisions of this Agreement.

 

(b)
       Adjustments for Changes in Capital Structure. If, as a result of any reorganization,
recapitalization, reincorporation, reclassification, stock dividend, stock split, reverse stock split or other similar change
in the Common Stock, the outstanding shares of Common Stock are increased or decreased or are exchanged for a different number
or kind of shares of the Company’s stock, the restrictions contained in this Agreement shall apply with equal force to additional
and/or substitute securities, if any, received by the Optionee in exchange for, or by virtue of his or her ownership of, Option
Shares.

    3

     

    

(c)
       Change and Modifications. This Agreement may not be orally changed, modified or terminated,
nor shall any oral waiver of any of its terms be effective. This Agreement may be changed, modified or terminated only by
an agreement in writing signed by the Company and the Optionee.

 

(d)
       Governing Law. This Agreement shall be governed by and construed in accordance with
the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters shall
be governed by and construed in accordance with the internal laws of the Commonwealth of Massachusetts, without regard to conflict
of law principles that would result in the application of any law other than the law of the Commonwealth of Massachusetts.

 

(e)
       Headings. The headings are intended only for convenience in finding the subject matter
and do not constitute part of the text of this Agreement and shall not be considered in the interpretation of this Agreement.

 

(f)
        Saving Clause. If any provision(s) of this Agreement shall be determined to be
illegal or unenforceable, such determination shall in no manner affect the legality or enforceability of any other provision hereof.

 

(g)
       Notices. All notices, requests, consents and other communications shall be in writing
and be deemed given when delivered personally, by telex or facsimile transmission or when received if mailed by first class registered
or certified mail, postage prepaid. Notices to the Company or the Optionee shall be addressed as set forth underneath their signatures
below, or to such other address or addresses as may have been furnished by such party in writing to the other.

 

(h)
       Benefit and Binding Effect. This Agreement shall be binding upon and shall inure to
the benefit of the parties hereto, their respective successors, permitted assigns, and legal representatives. The Company has
the right to assign this Agreement, and such assignee shall become entitled to all the rights of the Company hereunder to the
extent of such assignment.

 

(i)
        Counterparts. For the convenience of the parties and to facilitate execution,
this Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which shall
constitute one and the same document.

 

7.
           Dispute Resolution.

 

(a)
       Except as provided below, any dispute arising out of or relating to the Plan or this Stock
Option, this Agreement, or the breach, termination or validity of the Plan, this Stock Option or this Agreement, shall be finally
settled by binding arbitration conducted expeditiously in accordance with the J.A.M.S./Endispute Comprehensive Arbitration Rules
and Procedures (the “J.A.M.S. Rules”). The arbitration shall be governed by the United States Arbitration Act,
9 U.S.C. Sections 1 16, and judgment upon the award rendered by the arbitrators may be entered by any court having jurisdiction
thereof. The place of arbitration shall be Boston, Massachusetts.

    4

     

    

(b)
       The arbitration shall commence within 60 days of the date on which a written demand for arbitration
is filed by any party hereto. In connection with the arbitration proceeding, the arbitrator shall have the power to order the
production of documents by each party and any third-party witnesses. In addition, each party may take up to three depositions
as of right, and the arbitrator may in his or her discretion allow additional depositions upon good cause shown by the moving
party. However, the arbitrator shall not have the power to order the answering of interrogatories or the response to requests
for admission. In connection with any arbitration, each party to the arbitration shall provide to the other, no later than seven
business days before the date of the arbitration, the identity of all persons that may testify at the arbitration and a copy of
all documents that may be introduced at the arbitration or considered or used by a party’s witness or expert. The arbitrator’s
decision and award shall be made and delivered within six months of the selection of the arbitrator. The arbitrator’s decision
shall set forth a reasoned basis for any award of damages or finding of liability. The arbitrator shall not have power to award
damages in excess of actual compensatory damages and shall not multiply actual damages or award punitive damages, and each party
hereby irrevocably waives any claim to such damages.

 

(c)
        The Company, the Optionee, each party to the Agreement and any other holder of Stock
issued pursuant to this Agreement (each, a “Party”) covenants and agrees that such party will participate in the arbitration
in good faith. This Section 7 applies equally to requests for temporary, preliminary or permanent injunctive relief, except that
in the case of temporary or preliminary injunctive relief any party may proceed in court without prior arbitration for the limited
purpose of avoiding immediate and irreparable harm.

 

(d)
        Each Party (i) hereby irrevocably submits to the jurisdiction of any United States District
Court of competent jurisdiction for the purpose of enforcing the award or decision in any such proceeding, (ii) hereby waives,
and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that
it is not subject personally to the jurisdiction of the above named courts, that its property is exempt or immune from attachment
or execution (except as protected by applicable law), that the suit, action or proceeding is brought in an inconvenient forum,
that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced
in or by such court, and (iii) hereby waives and agrees not to seek any review by any court of any other jurisdiction which may
be called upon to grant an enforcement of the judgment of any such court. Each Party hereby consents to service of process by
registered mail at the address to which notices are to be given. Each Party agrees that its, his or her submission to jurisdiction
and its, his or her consent to service of process by mail is made for the express benefit of each other Party. Final judgment
against any Party in any such action, suit or proceeding may be enforced in other jurisdictions by suit, action or proceeding
on the judgment, or in any other manner provided by or pursuant to the laws of such other jurisdiction.

Pursuant
to the Rapid Micro Biosystems, Inc. 2010 Stock Option and Grant Plan (the “Plan”), Rapid Micro Biosystems, Inc.,
a Delaware corporation (together with any successor thereto, the “Company”), hereby grants to the Optionee, who
is employed by the Company or any of its Subsidiaries, an option (the “Stock Option”) to purchase on or prior to
the Expiration Date, or such earlier date as is specified herein, all or any part of the number of shares of Common Stock,
par value $.01 per share (“Common Stock”), of the Company indicated above (the “Underlying Shares,”
and such shares once issued shall be referred to as the “Option Shares”), at the Option Exercise Price per share,
subject to the terms and conditions set forth in this Incentive Stock Option Agreement (this “Agreement”) and in
the Plan. This Stock Option is intended to qualify as an “incentive stock option” as defined in Section 422(b) of
the Internal Revenue Code of 1986, as amended from time to time (the “Code”). To the extent that any portion of
the Stock Option does not so qualify, it shall be deemed a non-qualified stock option.

 

All
capitalized terms used herein and not otherwise defined shall have the respective meanings set forth in the Plan.

 

1.
           Vesting, Exercisability and Termination.

 

(a)
       No portion of this Stock Option may be exercised until such portion shall have vested and
become exercisable.

 

(b)
       Except as set forth below, and subject to the determination of the Committee in its sole discretion
to accelerate the vesting schedule hereunder, this Stock Option shall become vested and exercisable as set forth in the Grant
Summary.

    

     

    

Notwithstanding anything herein to the contrary in the case of a Sale Event, this Stock Option shall be treated as provided
in Section 3(c) of the Plan; provided, however, notwithstanding anything herein to the contrary, in the event (and only in
the event) that this Stock Option is assumed or continued by the Company or its successor entity in the sole discretion of
the parties to a Sale Event and thereafter remains in effect following such Sale Event, then 100% of the then-unvested Underlying
Shares shall be deemed vested and exercisable in full upon the date on which the Optionee’s Service Relationship with
the Company and its Subsidiaries or successor entity terminates if (A) such termination occurs in connection with and effective
as of the date of, or within 12 months following the date of, such Sale Event and (B) such termination is either by the Company
without Cause or by the Optionee for Good Reason. For purposes of this Stock Option, Good Reason shall mean (i) a material
diminution in the Optionee’s base salary except for across-the-board salary reductions based on the Company’s
financial performance similarly affecting all or substantially all senior management employees of the Company, (ii) a change
of more than 50 miles in the geographic location at which the Optionee provides services to the Company or (iii) a material
reduction in the Optionee’s job responsibilities, provided that neither a mere change in title alone nor reassignment
to a substantially similar position shall constitute a material reduction in job responsibilities. Notwithstanding the foregoing,
a resignation shall not be for Good Reason unless (A) the Optionee has provided the Company or the successor company, within
60 days of the initial occurrence of the Good Reason event, written notice stating with reasonable specificity the applicable
facts and circumstances underlying such finding of Good Reason; (B) the Company or the successor company fails to cure such
condition within 30 days after receiving such written notice; and (C) the Optionee’s resignation based on such Good
Reason is effective within 30 days after the expiration of such cure period.

 

(c)
          Termination. Except as may otherwise be provided by the Committee, if the Optionee’s
Service Relationship is terminated, the period within which to exercise this Stock Option will be subject to earlier termination
as set forth below (and if not exercised within such period, shall thereafter terminate subject, in each case to Section 3(c)
of the Plan):

 

(i)
        Termination Due to Death or Disability. If the Optionee’s Service Relationship
terminates by reason of such Optionee’s death or disability (as defined in Section 422(c) of the Code), this Stock
Option may be exercised, to the extent exercisable on the date of such termination, by the Optionee, the Optionee’s legal
representative or legatee for a period of 12 months from the date of death or disability or until the Expiration Date, if earlier.

 

(ii)
        Other Termination. If the Optionee’s Service Relationship terminates for
any reason other than death or disability (as defined in Section 422(c) of the Code), and unless otherwise determined by the Committee,
this Stock Option may be exercised, to the extent exercisable on the date of termination, for a period of 90 days from the date
of termination or until the Expiration Date or other termination date, if earlier; provided  however, if the
Optionee’s Service Relationship is terminated for Cause, this Stock Option shall terminate immediately upon the date of
such termination.

    2

     

    

For
purposes hereof, the Committee’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. Any portion of this Stock Option that
is not exercisable on the date of termination of the Service Relationship shall terminate immediately and be null and void.

 

(d)
       It is understood and intended that this Stock Option is intended to qualify as an “incentive
stock option” as defined in Section 422 of the Code to the extent permitted under applicable law. Accordingly, the Optionee
understands that in order to obtain the benefits of an incentive stock option under Section 422 of the Code, no sale or other
disposition may be made of Option Shares for which incentive stock option treatment is desired within the one-year period beginning
on the day after the day of the transfer of such Option Shares to him or her, nor within the two-year period beginning on the
day after Grant Date of this Stock Option and further 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. If the
Optionee disposes (whether by sale, gift, transfer or otherwise) of any such Option Shares within either of these periods, he
or she will notify the Company within 30 days after such disposition. The Optionee also agrees to provide the Company with any
information concerning any such dispositions required by the Company for tax purposes. Further, to the extent the Underlying Shares
and any other incentive stock options of the Optionee having an aggregate Fair Market Value in excess of $100,000 (determined
as of the Grant Date) first become exercisable in any year, such options will not qualify as incentive stock options.

 

2.
           Exercise of Stock Option.

 

(a)
       The Optionee may exercise this Stock Option only in the following manner: Prior to the Expiration
Date, the Optionee may deliver a Stock Option exercise notice (an “Exercise Notice”) in the form of Appendix
A hereto indicating his or her election to purchase some or all of the Underlying Shares with respect to which this Stock
Option is exercisable at the time of such notice. Such notice shall specify the number of Underlying Shares to be purchased. Payment
of the purchase price may be made by one or more of the methods described in Sections 5(a)(iv)(A), (B), (C) or (D) of the Plan,
subject to the limitations contained in such Sections of the Plan, including the requirement that the Committee specifically approve
in advance certain payment methods.

 

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

 

3.          
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.

 

4.
           Transferability of Stock Option. This Agreement is personal to the
Optionee and is not transferable by the Optionee in any manner other than by will or by the laws of descent and distribution.
The Stock Option may be exercised during the Optionee’s lifetime only by the Optionee (or by the Optionee’s guardian
or personal representative in the event of the Optionee’s incapacity). The Optionee may elect to designate a beneficiary
by providing written notice of the name of such beneficiary to the Company, and may revoke or change such designation at any time
by filing written notice of revocation or change with the Company; such beneficiary may exercise the Optionee’s Stock Option
in the event of the Optionee’s death to the extent provided herein. If the Optionee does not designate a beneficiary, or
if the designated beneficiary predeceases the Optionee, the legal representative of the Optionee may exercise this Stock Option
to the extent provided herein in the event of the Optionee’s death.

    3

     

    

5.
          Restrictions on Transfer of Option Shares. The Option Shares acquired
upon exercise of the Stock Option shall be subject to certain transfer restrictions and other limitations including, without limitation,
the provisions contained in Section 9 of the Plan.

 

6.
          Miscellaneous Provisions.

 

(a)
       Equitable Relief. The parties hereto agree and declare that legal remedies may be inadequate
to enforce the provisions of this Agreement and that equitable relief, including specific performance and injunctive relief, may
be used to enforce the provisions of this Agreement.

 

(b)
       Adjustments for Changes in Capital Structure. If, as a result of any reorganization,
recapitalization, reincorporation, reclassification, stock dividend, stock split, reverse stock split or other similar change
in the Common Stock, the outstanding shares of Common Stock are increased or decreased or are exchanged for a different number
or kind of shares of the Company’s stock, the restrictions contained in this Agreement shall apply with equal force to additional
and/or substitute securities, if any, received by the Optionee in exchange for, or by virtue of his or her ownership of, Option
Shares.

 

(c)
       Change and Modifications. This Agreement may not be orally changed, modified or terminated,
nor shall any oral waiver of any of its terms be effective. This Agreement may be changed, modified or terminated only by
an agreement in writing signed by the Company and the Optionee.

 

(d)
       Governing Law. This Agreement shall be governed by and construed in accordance with
the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters shall
be governed by and construed in accordance with the internal laws of the Commonwealth of Massachusetts, without regard to conflict
of law principles that would result in the application of any law other than the law of the Commonwealth of Massachusetts.

 

(e)
       Headings. The headings are intended only for convenience in finding the subject matter
and do not constitute part of the text of this Agreement and shall not be considered in the interpretation of this Agreement.

 

(f)
        Saving Clause. If any provision(s) of this Agreement shall be determined to be
illegal or unenforceable, such determination shall in no manner affect the legality or enforceability of any other provision hereof.

 

(g)
       Notices. All notices, requests, consents and other communications shall be in writing
and be deemed given when delivered personally, by telex or facsimile transmission or when received if mailed by first class registered
or certified mail, postage prepaid. Notices to the Company or the Optionee shall be addressed as set forth underneath their signatures
below, or to such other address or addresses as may have been furnished by such party in writing to the other.

          Dispute Resolution.

 

(a)
       Except as provided below, any dispute arising out of or relating to the Plan or this Stock
Option, this Agreement, or the breach, termination or validity of the Plan, this Stock Option or this Agreement, shall be finally
settled by binding arbitration conducted expeditiously in accordance with the J.A.M.S./Endispute Comprehensive Arbitration Rules
and Procedures (the “J.A.M.S. Rules”). The arbitration shall be governed by the United States Arbitration Act,
9 U.S.C. Sections 1 16, and judgment upon the award rendered by the arbitrators may be entered by any court having jurisdiction
thereof. The place of arbitration shall be Boston, Massachusetts.

 

(b)
       The arbitration shall commence within 60 days of the date on which a written demand for arbitration
is filed by any party hereto. In connection with the arbitration proceeding, the arbitrator shall have the power to order the
production of documents by each party and any third-party witnesses. In addition, each party may take up to three depositions

hereby irrevocably waives any claim to such damages.

 

(c)
        The Company, the Optionee, each party to the Agreement and any other holder of Stock
issued pursuant to this Agreement (each, a “Party”) covenants and agrees that such party will participate in the arbitration
in good faith. This Section 7 applies equally to requests for temporary, preliminary or permanent injunctive relief, except that
in the case of temporary or preliminary injunctive relief any party may proceed in court without prior arbitration for the limited
purpose of avoiding immediate and irreparable harm.

    5

     

    

(d)
        Each Party (i) hereby irrevocably submits to the jurisdiction of any United States District
Court of competent jurisdiction for the purpose of enforcing the award or decision in any such proceeding, (ii) hereby waives,
and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that
it is not subject personally to the jurisdiction of the above named courts, that its property is exempt or immune from attachment
or execution (except as protected by applicable law), that the suit, action or proceeding is brought in an inconvenient forum,
that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced
in or by such court, and (iii) hereby waives and agrees not to seek any review by any court of any other jurisdiction which may
be called upon to grant an enforcement of the judgment of any such court. Each Party hereby consents to service of process by
registered mail at the address to which notices are to be given. Each Party agrees that its, his or her submission to jurisdiction
and its, his or her consent to service of process by mail is made for the express benefit of each other Party. Final judgment
against any Party in any such action, suit or proceeding may be enforced in other jurisdictions by suit, action or proceeding
on the judgment, or in any other manner provided by or pursuant to the laws of such other jurisdiction.

shares once issued shall be referred to as the “Option Shares”), at the Option Exercise Price per share, subject to
the terms and conditions set forth in this Non-Qualified Stock Option Agreement (this “Agreement”) and in the Plan.
This Stock Option is not intended to qualify as an “incentive stock option” as defined in Section 422(b) of the Internal
Revenue Code of 1986, as amended from time to time (the “Code”).

 

All capitalized terms used herein
and not otherwise defined shall have the respective meanings set forth in the Plan.

 

		1.	Vesting, Exercisability and Termination.

 

(a)            No
portion of this Stock Option may be exercised until such portion shall have vested and become exercisable.

 

(b)           Subject
to the determination of the Committee in its sole discretion to accelerate the vesting schedule hereunder, this Stock Option shall
become vested and exercisable as set forth in the Grant Summary. Notwithstanding anything herein to the contrary in the case of
a Sale Event, this Stock Option shall be treated as provided in Section 3(c) of the Plan.

     

     

    

(c)           Termination.
Except as may otherwise be provided by the Committee, if the Optionee’s Service Relationship is terminated, the period within
which to exercise this Stock Option will be subject to earlier termination as set forth below (and if not exercised within such
period, shall thereafter terminate subject, in each case to Section 3(c) of the Plan):

 

(i)            Termination
Due to Death or Disability. If the Optionee’s Service Relationship terminates by reason of such Optionee’s death

date of such termination, by the Optionee, the Optionee’s legal representative or legatee for a period of 12 months from
the date of death or disability or until the Expiration Date, if earlier.

 

(ii)           Other
Termination. If the Optionee’s Service Relationship terminates for any reason other than death or disability (as defined
in Section 422(c) of the Code), and unless otherwise determined by the Committee, this Stock Option may be exercised, to the extent
exercisable on the date of termination, for a period of 90 days from the date of termination or until the Expiration Date or other
termination date, if earlier; provided however, if the Optionee’s Service Relationship is terminated for Cause, this
Stock Option shall terminate immediately upon the date of such termination.

 

For purposes hereof, the Committee’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 and any Permitted Transferee. Any portion of this Stock Option that is not
exercisable on the date of termination of the Service Relationship shall terminate immediately and be null and void.

 

		2.	Exercise of Stock Option.

 

(a)           The
Optionee may exercise this Stock Option only in the following manner: Prior to the Expiration Date, the Optionee may deliver a
Stock Option exercise notice (an “Exercise Notice”) in the form of Appendix A hereto indicating his or her election
to purchase some or all of the Underlying Shares with respect to which this Stock Option is exercisable at the time of such notice.
Such notice shall specify the number of Underlying Shares to be purchased. Payment of the purchase price may be made by one or
more of the methods described in Sections 5(a)(iv)(A), (B), (C), (D) or (E) of the Plan, subject to the limitations contained in
such Sections of the Plan, including the requirement that the Committee specifically approve in advance certain payment methods.

 

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

 

3.            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.

 

4.            Transferability
of Stock Option. This Agreement is personal to the Optionee and is not transferable by the Optionee in any manner other than
by will or by the laws of descent and distribution. The Stock Option may be exercised during the Optionee’s lifetime only
by the Optionee (or by the Optionee’s guardian or personal representative in the event of the Optionee’s incapacity).
The Optionee may elect to designate a beneficiary by providing written notice of the name of such beneficiary to the Company, and
may revoke or change such designation at any time by filing written notice of revocation or change with the Company; such beneficiary
may exercise the Optionee’s Stock Option in the event of the Optionee’s death to the extent provided herein. If the
Optionee does not designate a beneficiary, or if the designated beneficiary predeceases the Optionee, the legal representative
of the Optionee may exercise this Stock Option to the extent provided herein in the event of the Optionee’s death.

    2

     

    

5.            Restrictions
on Transfer of Option Shares. The Option Shares acquired upon exercise of the Stock Option shall be subject to certain transfer
restrictions and other limitations including, without limitation, the provisions contained in Section 9 of the Plan.

Provisions.

 

(a)            Equitable

and that equitable relief, including specific performance and injunctive relief, may be used to enforce the provisions of this
Agreement.

Stock are increased or decreased or are exchanged for a different number or kind of shares of the Company’s stock, the restrictions
contained in this Agreement shall apply with equal force to additional and/or substitute securities, if any, received by the Optionee
in exchange for, or by virtue of his or her ownership of, Option Shares.

 

(c)            Change
and Modifications. This Agreement may not be orally changed, modified or terminated, nor shall any oral waiver of any of its
terms be effective. This Agreement may be changed, modified or terminated only by an agreement in writing signed by the Company
and the Optionee.

 

(d)           Governing
Law. This Agreement shall be governed by and construed in accordance with the General Corporation Law of the State of Delaware
as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal
laws of the Commonwealth of Massachusetts, without regard to conflict of law principles that would result in the application of
any law other than the law of the Commonwealth of Massachusetts.

 

(e)            Headings.
The headings are intended only for convenience in finding the subject matter and do not constitute part of the text of this Agreement
and shall not be considered in the interpretation of this Agreement.

 

(f)            Saving Clause. If any provision(s)

as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction
of the above named courts, that its property is exempt or immune from attachment or execution (except as protected by applicable
law), that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding
is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and (iii) hereby waives
and agrees not to seek any review by any court of any other jurisdiction which may be called upon to grant an enforcement of the
judgment of any such court. Each Party hereby consents to service of process by registered mail at the address to which notices

on later of (i) the Basic Rent Commencement Date, or (ii) thirty (30) days after the signing of the amendment described below, Tenant
shall pay additional Basic Rent to Landlord in equal monthly installments to amortize the full amount of the TI Allowance Increase over
the remainder of the Initial Term, with an interest rate equal to 9% per annum. (In other words, the amount of the TI Allowance Increase
shall be considered as though such amount were a direct reduction loan which will be repaid in full at such interest rate over the Initial
Term, and with the amount of payments in each such Lease Year of the Initial Term being additional Basic Rent payable in equal monthly
installments.)
	 	 	 
	 	This provision shall be self-operative, but in confirmation hereof Tenant shall execute an amendment to this Lease setting forth the additional Basic Rent to be paid on account of the TI Allowance Increase.
	 	 
	Early Access Period	The time period beginning on the Date of Lease and ending on the Term Commencement Date during which period Tenant will have access to the Premises, the space below the Premises on the second floor, and loading docks “12, 13 and 14” for the construction of the Improvements as described in Section 3.  During this period, Tenant will not be obligated to pay Basic Rent, Additional Rent or utilities (provided, however, that during the Early Access Period Tenant shall pay Tenant’s Pro Rata Share of Additional Rent and utilities, but not Basic Rent, in respect of the Clean Room Premises).

and the three shared loading docks numbered “12, 13 and 14” located in POD LG/A8 of the Building subject always to
reasonable rules and regulations established from time to time by Landlord. The current rules and regulations for the Building are

this Lease, Tenant shall have access to the Premises, the common areas, including the parking spaces, and the loading docks
twenty-four hours per day, seven days per week.

 

    4 

     

    

 

Tenant warrants and represents that Tenant has
had full opportunity to inspect the Premises, Building and Property and, subject to Landlord’s obligations expressly set forth in
this Lease, takes the Premises, Building and Property “as is, where is, with all faults”. The Tenant’s execution of
this Lease shall be presumptive evidence that the Premises and the Building are in the condition required under this Lease subject, however,
to Landlord’s obligations expressly set forth in this Lease. Except as expressly set forth in this Lease, neither Landlord nor any
person acting under Landlord has made any representations or promises with respect to the condition of the Premises, the Building, the
Property or the fitness of any of the foregoing for Tenant’s use or regarding any other matter or thing relating to any of the foregoing,
and Tenant’s rights with respect to the Premises, the Building, the Property and Landlord are solely and exclusively set forth in
this Lease.

 

Landlord reserves the right from time to time,
with telephonic notice and without unreasonable (except in emergency) interruption of Tenant’s use: (a) to install, use, maintain,
repair, replace and relocate for service to the Premises and other parts of the Building, or either, pipes, ducts, conduits, wires and
appurtenant fixtures, or any other Building systems or equipment, wherever located in the Premises or the Building and (b) to alter or
relocate any other common facility, including without limitation any lobby, courtyard or other common areas. Installations, replacements
and relocations referred to in clause (a) above shall be located as far as practicable in the central core area of the Building, above
ceiling surfaces, below floor surfaces or within perimeter walls of the Premises. Landlord shall provide Tenant with reasonable prior
notice of any such activity and shall use reasonable efforts to schedule the making thereof so as to minimize to the extent practicable
the interference with Tenant’s business operations.

 

		3.	Construction of Improvements.

 

All leasehold improvements constructed by or on
behalf of Tenant within the Premises (“Tenant Work”) shall be done in accordance with plans and specifications prepared and
stamped by a licensed architect and first approved by Landlord which approval shall not be unreasonably withheld, conditioned or delayed.
Landlord shall review Tenant’s construction plans and specifications as provided for below. In any event, cosmetic work such as
painting, carpeting and wall coverings shall not require Landlord’s consent and no prior notice to Landlord of such work is required.

 

    5 

     

    

 

Within ten (10) business days following
Landlord’s receipt of the plans and specifications for any Tenant Work, Landlord shall have the right to notify Tenant as to
which portions of such Tenant Work must be removed by Tenant at the expiration or earlier termination of this Lease (the
 “Removal Items”), and the Removal Items so designated by Landlord within said ten (10) business day period shall be
removed by Tenant at the expiration or earlier termination of this Lease, and Tenant shall repair any damage cause by such removal
and restore that portion of the Premises to the condition the Premises were in prior to the installation of the Removal Items,
reasonable wear and tear and damage by fire or other casualty or taking excepted. Other than the Removal Items, Tenant shall have no
obligation, upon the expiration or earlier termination of this Lease, to remove any component of the Tenant Work or any cabling, but
Tenant may remove any fixtures or equipment installed as part of the Tenant Work or remove trade fixtures that are specific to
Tenant’s business operations.

 

All Tenant Work shall be done by qualified
contractors and laborers, in a good and workmanlike manner and in full compliance with this Lease and all applicable laws and lawful
ordinances, regulations and orders of governmental authorities and insurers of the Building and/or the Premises. Before Tenant
begins any Tenant Work, it shall (i) secure all licenses and permits necessary therefor (it being understood that Landlord shall, at
Tenant’s expense, cooperate with Tenant in securing all such licenses and permits), (ii) deliver to Landlord a statement with
names of all its contractors and subcontractors and the estimated cost of all labor and material to be furnished by them (iii) cause
each contractor and subcontractor to carry (1) workers’ compensation insurance in statutory amounts and employer’s
liability insurance with limits not less than $1,000,000 per accident covering all the contractor’s and subcontractor’s
employees, and (2) comprehensive general liability insurance with such limits as Landlord may reasonably require, but in no event
less than $10,000,000 combined single limit for bodily injury and property damage insurance, all such insurance to include coverage
for premises operations, broad form property damage, owner’s and contractor’s protective liability and completed
operations for one (1) year; provided, however, that for Tenant’s Initial Construction (as defined in Exhibit C)
during the Early Access Period, the combined single limit for the comprehensive general liability insurance and umbrella excess
liability insurance shall be $5,000,000, and (iv) obtain all risks property insurance against loss or damage to Tenant’s work
pending completion of the improvements. All insurance referred to in clauses (iii) and (iv) above shall be written by companies
reasonably approved by Landlord and shall insure Landlord, Landlord’s property managers and sub-managers, Mortgagees, the
names and addresses of which shall be provided by Landlord to Tenant, and Tenant as additional insureds, as their respective
interests may appear, as well as the contractors and subcontractors as appropriate, and all such insurance shall contain a waiver of
subrogation provision in favor of all insureds and shall be primary coverage as to any other coverage maintained by any insured
other than Tenant. Prior to commencing any work within the Premises, Tenant shall deliver, or arrange to be delivered, to Landlord:
(a) certificates of all insurance referred to in clauses (iii) and (iv) above; and (b) a lien and completion bond, bank letter of
credit, or other security satisfactory to Landlord, in an amount adequate, in Landlord’s judgment, to protect Landlord against
materials and mechanics’ liens which may be filed in connection with such work and to insure completion of such work. The
foregoing notwithstanding, Tenant agrees to promptly pay when due the entire cost of any Tenant Work, and not to cause or permit any
liens for work to attach to the Premises or the Building and immediately to discharge or bond off any such liens which may attach.
Landlord may inspect any Tenant Work at any reasonable time upon reasonable notice; provided, however, Landlord shall, except in
case of emergency, (i) give Tenant not less than 24 hours’ prior notice of such inspections and (ii) conduct such inspections
so as to minimize interference with the construction work of Tenant. Tenant shall, and shall require its contractors to, insure and
indemnify Landlord and hold it harmless from and against any cost, claim or liability arising from any Tenant Work, all such
insurance and evidence of indemnification to be in form and substance reasonably satisfactory to Landlord.

 

Tenant, at Tenant’s expense (but Landlord
shall provide the Tenant Improvement Allowance described in Section 1 and in Exhibit C), shall perform all Tenant Work
considered necessary or desirable by Tenant to make the Premises ready for Tenant’s occupancy in accordance with the provisions
of Exhibit C, other than the Landlord’s work described on the attached Exhibit C-1. Except as otherwise
provided on the attached Exhibit C-1, such Landlord’s work shall be performed by Landlord (or at Landlord’s direction)
during the Early Access Period and completed prior to the Term Commencement Date, subject to Section 31 below.

 

    6 

     

    

 

		4.	Term

 

The Initial Term of this Lease shall commence on
the Term Commencement Date and shall expire, unless earlier extended or terminated in accordance with the terms hereof, on the Termination
Date. Notwithstanding the foregoing, Tenant shall have access to the Premises (and, as appropriate and with Landlord’s prior written
approval to the common areas of the Building) during the Early Access Period for the purpose of undertaking and completing Tenant’s
Initial Construction, provided that Tenant’s Initial Construction shall be coordinated with Landlord’s work described on the
attached Exhibit C-1 so as not to unreasonably interfere with such Landlord’s work, and provided further, that Tenant’s
Initial Construction shall include all work performed by Tenant in the Clean Room Premises. Such access shall be subject to all applicable
provisions of this Lease, except that Tenant shall not be charged any Basic Rent, Additional Rent, or utilities in connection therewith.
Landlord and Tenant acknowledge that Tenant requires access to the premises of another tenant in the Building in connection with Tenant’s
Initial Construction, and Landlord shall use commercially reasonable efforts to coordinate such efforts with such tenant (and any such
access shall be subject to the applicable provisions of this Lease).

 

So long as Tenant is not in default beyond any
applicable cure period at the time Tenant elects to extend the Term, or at the time the Term would expire but for such extension, Tenant
shall have the option to extend the Term for one (1) five (5) year extension term (the “Extension Term”) by unconditional
notice given to Landlord at least nine (9) months before the Termination Date (the “Tenant’s Extension Notice”) with
respect to the Premises including within such notice Tenant’s estimate of Fair Market Rent, all as described below. If Tenant fails
timely so to exercise its option for the Extension Term, time being of the essence, Tenant shall have no further extension rights hereunder.

 

During the Extension Term, Tenant shall pay
Basic Rent for the first Lease Year of such Extension Term equal to the Fair Market Rent for the Premises for the first Lease Year
of such Extension Term, but in no event shall Basic Rent ever be less than Basic Rent in effect with respect to the Premises during
the last Lease Year of the Initial Term. During each subsequent Lease Year of the Extension Term thereafter, the annual Basic Rent
shall increase by Twenty Five Cents ($0.25) per rentable square foot of the Premises. For purposes hereof, “Fair Market
Rent” shall mean the then prevailing market rent taking into account all relevant factors, including without limitation,
tenant improvement allowances and any concessions then being offered in the marketplace for space of comparable size, quality and
location. within the Route 495 North submarket for comparable terms.

 

    7 

     

    

 

Tenant’s Extension Notice shall include Tenant’s
estimate of Fair Market Rent. Landlord shall notify Tenant of its estimate of the Fair Market Rent within thirty (30) days after receipt
of Tenant’s Extension Notice. If either (y) Landlord rejects Tenant’s estimate or (z) Landlord fails in writing to notify
Tenant of Landlord’s approval of Tenant’s estimate, then the Fair Market Rent shall be arbitrated in accordance with the following
procedure.

 

If Landlord and Tenant have not agreed on the amount
of Fair Market Rent within thirty (30) days after Landlord’s rejection (or deemed rejection) of Tenant’s estimate thereof,
or if the arbitration procedure for determination of Fair Market Rent is otherwise commenced pursuant to the prior paragraph, then the
arbitration shall be conducted in daylight baseball style where each party shall submit to the arbitrator and exchange with each other
in advance of the hearing a report containing their last and best estimate of the Fair Market Rent and evidence bearing on the determination
of the Fair Market Rent. The arbitrator will be appointed by mutual agreement of the parties from the first or second list of arbitrators
offered by the American Arbitration Association; if the parties cannot agree on the selection of the arbitrator, then the AAA will select
the arbitrator. The arbitrator shall be an appraiser who shall have had at least ten (10) years experience in the leasing, ownership or
management of office/manufacturing buildings similar in character to the Premises and shall be a member of A.S.R.E.C. (or successor professional
organization). The arbitrator shall, within 15 days after the conclusion of the arbitration hearing, issue a written statement of decision
that selects either the Landlord’s or the Tenant’s estimate of Fair Market Rent. The arbitration shall be conducted in accordance
with the commercial arbitration rules of the AAA insofar as such rules are not inconsistent with the provisions of this Lease (in which
case the provisions of this Lease shall govern). The parties shall have reasonable opportunity to present evidence bearing on Fair Market
Rent. The cost of the arbitration (exclusive of each party’s witness and attorneys fees, which shall be paid by such party) shall
be borne equally by the parties. If the AAA shall cease to provide arbitration for commercial disputes in Boston, the second or third
arbitrator, as the case may be, shall be appointed by JAMS or any successor organization to either JAMS or the AAA providing substantially
the same services, and in the absence of such an organization, by a court of competent jurisdiction under the arbitration act of The Commonwealth
of Massachusetts. The decision of the arbitrator shall be final and the determination of Fair Market Rent shall be binding on the parties.

 

If the valuation procedures of this Section are
delayed for any reason, then such procedures shall nevertheless remain in effect and be applicable when and as invoked with respect to
Basic Rent payable during the Extension Term; but until such procedures are completed, Tenant shall pay on account of Basic Rent at the
rate established for Basic Rent for the last twelve (12) months of the Initial Term (and upon Fair Market Rent being established, Tenant
shall pay the new rent within ten (10) days of such determination, retroactively to the beginning of the applicable Extension Term). The
parties shall adjust for over or under payments within twenty (20) days after the decision of the arbitrators is announced.

 

    8 

     

    

 

Promptly after the Basic Rent is determined
for the Extension Term as aforesaid, Landlord and Tenant shall enter into an amendment of this Lease confirming the extension of the
Term and the new rate for Basic Rent.

 

Tenant’s rights to extend the Term under
this Section are personal to Tenant and shall not apply to any Transferee of Tenant (other than a Transferee under a Permitted Transfer)
and shall not be assignable or exercisable by any other person or entity (other than a Transferee under a Permitted Transfer). If at any
time during the Term Tenant has Transferred more than one half (1/2) of rentable square feet of the Premises (not including Permitted
Transfers), then Tenant’s rights under this Section shall thereafter be null and void and of no further force or effect.

 

		5.	Use of the Premises; Licenses and Permits

 

Tenant may use the Premises only for office, light
manufacturing, wet laboratory, clean room and test/assembly purposes. The Premises may not be used for uses (a) of heavy equipment in
excess of the floor load capacity of the Building or resulting in excessive wear and tear on the Building, (b) except as expressly permitted
under Section 27, any use or storage of Hazardous Materials or Waste, and (c) in violation of any applicable local, state or federal
law, bylaw, code, rule or regulation. In addition to and without limiting the generality of the foregoing, in no event shall the Premises
be used for any heavy stamping or other operations that cause material vibrations in the ground floor manufacturing premises of Cobham
Defense Electronics Systems Corporation (or any successor or assign thereof).

 

		6.	Rent

 

6.1             
As consideration for this Lease Tenant covenants to pay to Landlord, without setoff, reduction, counterclaim or defense and, except
as otherwise expressly set forth herein, without abatement, the total amounts respectively of Basic Rent and Additional Rent for the Term
when due pursuant to this Lease. Tenant’s obligation to pay Basic Rent shall commence on the Basic Rent Commencement Date and Tenant’s
obligation to pay Additional Rent shall commence on the Term Commencement Date. On the first day of each month during the Term (i) the
respective amount of annual Basic Rent due for the Lease Year in question shall be paid in equal monthly installments in advance, (ii)
Tenant’s Pro Rata Share of Landlord’s Operating Expenses and Landlord’s Taxes shall be paid as Additional Rent as provided
in Section 6.3 below and (iii) Tenant’s Cafeteria Payment shall be paid as Additional Rent as provided in Section 6.3
below. Tenant shall make a ratable payment of Basic Rent and Additional Rent for any period of less than a month at the beginning or end
of the Term. All payments of Basic Rent, Additional Rent and other sums due shall be paid in current U.S. exchange by check drawn on a
federal clearinghouse bank at the address of Landlord set forth in Section 1 or such other place as Landlord may from time to time
direct (or if requested by Landlord in the case of Basic Rent, by electronic fund transfer). The term “rent” as used in this
Lease shall mean Basic Rent and Additional Rent and any other amount payable by Tenant under this Lease.

 

Without limiting the foregoing, except as
expressly set forth in this Lease, Tenant’s obligation so to pay rent shall not be discharged or otherwise affected by any law
or regulation now or hereafter applicable to the Premises, or any other restriction on Tenant’s use, or any casualty or
taking, or any failure by Landlord to perform any covenant contained herein, or any other occurrence; and, except as expressly set
forth in this Lease, Tenant waives all rights now or hereafter existing to terminate or cancel this Lease or quit or surrender the
Premises or any part thereof, or to assert any defense in the nature of constructive eviction to any action seeking to recover Rent.
Subject to the provisions of this Lease however, Tenant shall have the right to obtain judgments for direct money damages occasioned
by Landlord’s breach of its Lease covenants.

 

    9 

     

    

 

This Lease is intended by the parties hereto to
be a so-called “triple net” lease and, to the end that the Basic Rent shall be received by the Landlord net of all costs and
expenses related to the Property, the Building and the Premises, except as expressly set forth herein.

 

If any payment of Basic Rent or Additional Rent
is not paid to the Landlord when due or within any applicable grace period expressly provided herein, then at the Landlord’s option,
without notice and in addition to all other remedies hereunder, the Tenant shall pay upon demand to the Landlord as Additional Rent interest
thereon at an annual rate equal to ten percent (10%) per annum or the maximum rate permitted by applicable law if less, such interest
to be computed from the date such Basic Rent or Additional Rent was originally due through the date when paid in full, and if more than
two (2) late payments occur within any twelve (12) month period, Landlord may in addition to all of its other remedies impose an administrative
charge of five percent (5%) on the amount of any subsequent late payments, such interest and administrative charges being Additional Rent.

 

It is intended that rent payable hereunder shall
be a net-net-net return to Landlord throughout the Term, free of expense, charge, offset, diminution or other deduction whatsoever on
account of the Premises (excepting financing expenses, federal and state income taxes of general application and those expenses which
this Lease expressly makes the responsibility of Landlord), and all provisions hereof shall be construed in terms of such intent.

 

6.2             
Tenant covenants and agrees to pay to Landlord, commencing as of the date hereof with respect to the Clean Room Premises, and as
of the Term Commencement Date with respect to the entire Premises, as Additional Rent, (i) an amount equal to Tenant’s Pro Rata
Share of Landlord’s Operating Expenses, (ii) an amount equal to Tenant’s Pro Rata Share of Landlord’s Taxes and (iii)
an amount equal to Tenant’s Cafeteria Payment. With respect to amounts payable on account of Landlord’s Operating Expenses
pursuant to the foregoing clause (i), if less than the total rentable floor area of the Building is occupied at any time during such period,
Landlord may reasonably extrapolate and include all components of Landlord’s Operating Expenses that vary with occupancy as though
the total rentable floor area of the Building had been ninety-five percent (95%) occupied at all times during such period (that is, if
actual occupancy of the Building is less than 95%, then Tenant’s Pro Rata Share of any such extrapolated variable component will
be the percentage obtained by multiplying 95% by a fraction, the numerator of which is the percentage of the Building occupied by Tenant
and the denominator of which is the percentage of the Building occupied by Tenant and all other tenants). For purposes hereof, “Tenant’s
Cafeteria Payment” shall mean Landlord’s operating costs associated with the cafeteria multiplied by a fraction, the numerator
of which is the percentage of the Building occupied by Tenant and the denominator of which is the percentage of the Building occupied
by Tenant and all other tenants.

 

    10 

     

    

 

6.3             
 Additional Rent for Operating Expenses and Taxes and Tenant’s Cafeteria Payment under this Section shall be paid for
any portion of a month at the beginning of the Term and thereafter in monthly installments on the first day of each calendar month in
amounts reasonably estimated from time to time by Landlord for the then current calendar year or other fiscal period. Landlord may from
time to time revise such estimates based on available information relating to Landlord’s Operating Expenses and Taxes and Tenant’s
Cafeteria Payment or otherwise affecting the calculation hereunder. Within one hundred twenty (120) days after the end of each calendar
year or fiscal period, Landlord will provide Tenant with an accounting statement of Landlord’s Operating Expenses and Taxes and
Tenant’s Cafeteria Payment and other data necessary to calculate Additional Rent hereunder for such calendar year or fiscal period
prepared in reasonable “line item” detail, which statement shall be conclusive between the parties unless disputed by Tenant
pursuant to Section 6.6 below. Upon issuance thereof, there shall be an adjustment between Landlord and Tenant for the calendar year
or fiscal period covered by such accounting to the end that Landlord shall have received the exact amount of Additional Rent due hereunder.
Any overpayments by Tenant hereunder shall be credited against the next payments of Additional Rent due under this Section, provided there
are no outstanding amounts due Landlord under this Lease at such time. Any underpayments by Tenant shall be due and payable within thirty
(30) days of delivery of Landlord’s statement. With respect to the calendar year or fiscal period in which the Term ends, the adjustment
shall be pro rated for the portion of the year included in the Term, but shall take place nevertheless at the times provided in the preceding
sentences and shall survive the Term.

 

6.4              “Landlord’s
Operating Expenses” means all costs of Landlord in servicing, operating, managing, maintaining, and repairing the Building and
Property, and all improvements thereon and providing services to tenants including, without limitation, the costs of the following:
(i) supplies, materials and equipment purchased or rented, total wage and salary costs paid to, and all contract payments made on
account of, all persons (including persons employed by Landlord or its affiliates) engaged in the operation, maintenance, security,
cleaning and repair of the Building and Property, including Social Security, old age and unemployment taxes, sick and vacation pay
and other so-called “fringe benefits”; (ii) building services provided pursuant to Section 10, including
maintenance, repair and replacement of all components of the Building, including its structural components, roof, systems, equipment
and appurtenances, planting, landscaping and grounds, roads, sidewalks and parking areas, whether performed by Landlord’s or
Landlord’s affiliate’s employees or by other persons under contract with Landlord (but excluding costs to replace the
roof, foundation or structural frame of the Building during the Initial Term); (iii) utilities consumed and expenses incurred in the
operation, maintenance and repair of the Building and Property including, without limitation, oil, gas, electricity, water, sewer
and snow removal; (iv) casualty, liability, flood, environmental and other insurance, and unreimbursed costs incurred by Landlord
which are subject to an insurance deductible; (v) management fees in the amount of and not to exceed four percent (4%) of the gross
rental income and receipts of the Building and the Property and (vi) operating charges for any amenity available for use by tenants
of the Building (including, without limitation, any fitness center). If Landlord, in its reasonable discretion, installs a new or
replacement capital item (including, without limitation, any such capital item that is intended to improve the operating efficiency
of the Building and/or the Property), the cost of such item together with interest at two percentage points above the then
 “Prime Rate” (as published in the Wall Street Journal or comparable financial publication reasonably selected by
Landlord) considered as though such cost and interest comprised a direct reduction loan amortizing over (x) the useful life of such
item or (y) with respect to any such item that is intended to improve operating efficiency, the period during which such efficiency
shall be realized, as reasonably determined by Landlord, shall be included in Landlord’s Operating Expenses. Landlord’s
Operating Expenses shall not include (i) costs of electricity or utilities furnished directly to any premises of other tenants of
the Building where such utility is separately metered to such premises or such tenant pays a separate charge therefor; (ii) costs
incurred in connection with Landlord’s preparation, negotiation, dispute resolution and/or enforcement of leases, including
court costs and attorneys’ fees and disbursements in connection with any summary proceeding to dispossess any other tenant, or
incurred in connection with disputes with prospective tenants, leasing agents, purchasers or mortgagees; (iii) financing costs
including interest and principal amortization of debts and the costs of providing the same; (iv) any liabilities, costs or expenses
associated with or incurred in connection with the removal, enclosure, encapsulation or other handling of Hazardous Materials or
Wastes (as defined in Section 27 below) and the cost of defending against claims in regard to the existence or release of
Hazardous Materials or Wastes at the Building or the Property (except with respect to those costs for which Tenant is otherwise
responsible pursuant to the express terms of this Lease); and (vi) charitable or political contributions. Landlord’s Operating
Expenses shall be calculated in accordance with GAAP, consistently applied.

 

    11 

     

    

 

6.5             
“Landlord’s Taxes” or “Taxes” means all taxes, assessments and similar charges assessed or imposed
on the Property for the then current fiscal year by any governmental authority attributable to the Building and any associated parking
structure (including personal property associated with any of the foregoing). The amount of any special taxes, special assessments and
agreed or governmentally imposed “in lieu of tax” or similar charges shall be included in Landlord’s Taxes for any year
but shall be limited to the amount of the installment (plus any interest, other than penalty interest, payable thereon) of such special
tax, special assessment or such charge required to be paid during or with respect to the year in question. Landlord’s Taxes include
expenses, including fees of attorneys, appraisers and other consultants, incurred in connection with any efforts to obtain abatements
or reduction or to assure maintenance of Landlord’s Taxes for any year wholly or partially included in the Term, whether or not
successful and whether or not such efforts involved filing of actual abatement applications or initiation of formal proceedings. Landlord’s
Taxes exclude income taxes of general application and all estate, succession, inheritance and transfer taxes. If at any time during the
Term there shall be assessed on Landlord, in addition to or lieu of the whole or any part of the ad valorem tax on real or personal property,
a capital levy or other tax on the gross rents or other measures of building operations, or a governmental income, franchise, excise or
similar tax, assessment, levy, charge or fee measured by or based, in whole or in part, upon building valuation, gross rents or other
measures of building operations or benefits of governmental services furnished to the Building, then any and all of such taxes, assessments,
levies, charges and fees, to the extent so measured or based, shall be included within the term Landlord’s Taxes, but only to the
extent that the same would be payable if the Building and Property were the only property of Landlord.

 

    12 

     

    

 

6.6              At
Tenant’s written request at any time within three (3) months after Landlord delivers Landlord’s statement of
Landlord’s Operating Expenses and Taxes and Tenant’s Cafeteria Payment to Tenant, Tenant (at Tenant’s expense)
shall have the right to examine Landlord’s books and records applicable to Landlord’s Operating Expenses and Taxes and
Tenant’s Cafeteria Payment. Such right to examine the records shall be exercisable: (a) upon reasonable advance notice (which,
for purposes hereof, shall mean at least thirty (30) days) to Landlord and at reasonable times during Landlord’s business
hours; (b) only during the five (5) month period following Tenant’s receipt of Landlord’s statement for the applicable
calendar year and (c) not more than once each calendar year. Landlord’s statement shall be deemed conclusive except as to
items specifically disputed in writing by notice from Tenant to Landlord given within six (6) months after Landlord delivers the
statement to Tenant. Tenant shall pay all costs of the examination unless Tenant is found to have overpaid Additional Rent for
Operating Expenses and Taxes and Tenant’s Cafeteria Payment by more than five percent (5%) for the year in question, in which
event Landlord will be reimburse Tenant for all reasonable out-of-pocket costs of the examination in addition to any overpayment of
the Additional Rent. Any examination of Landlord’s Operating Expenses and Taxes shall be conducted by an independent certified
public accountant retained by Tenant (each, an “examiner”). In no event shall Tenant utilize any examiner who is being
paid on a contingent fee or any other basis where such examiner’s fee or compensation, in whole or in part, is determined by
any amount of Operating Expenses and Taxes and Tenant’s Cafeteria Payment overpaid. Landlord shall reasonably approve any
examiner to confirm compliance with the previous sentence. Landlord shall reasonably cooperate with Tenant and any examiner in the
performance of any examination of Landlord’s records pursuant to the terms hereof. Landlord and Tenant shall adjust for any
overpayments or underpayments determined by examination under this Section pursuant to Section 6.3 above.

 

As a condition precedent to performing any such
examination of Landlord’s books and records, Tenant and its examiner shall be required to execute and deliver to Landlord an agreement
in form acceptable to Landlord agreeing to keep confidential any information that they discover about Landlord or the Building in connection
with such examination. Without limiting the foregoing, such examiners shall also be required to agree that they will not represent any
other tenant in the Building in connection with examinations of Landlord’s books and records for the Building unless said tenant(s)
have retained said examiners prior to the date of the first examination of Landlord’s books and records conducted by Tenant pursuant
to this Section and have been continuously represented by such examiners since that time. Notwithstanding any prior approval of any
examiners by Landlord, Landlord shall have the right to rescind such approval at any time if in Landlord’s reasonable judgment the
examiners have breached any confidentiality undertaking to Landlord or any other landlord or cannot provide acceptable assurances and
procedures to maintain confidentiality.

 

		7.	Insurance; Waivers of Subrogation

 

Tenant shall, at its own cost and expense, maintain
during the Term insurance for the benefit of Tenant, Landlord, any Mortgagees and property managers (as their interests may appear) from
insurers rated at least A-/X by A.M. Best, with terms and coverages reasonably satisfactory to Landlord and with such increases in limits
as Landlord may from time to time reasonably request provided that such limits are the same as those then being provided by similar types
of tenants in the greater Boston area under leases of similar types of premises for similar uses, and/or as may be required by typical
institutional lenders of comparable properties. Initially, Tenant shall maintain the following on an occurrence basis (except as otherwise
expressly provided below):

 

    13 

     

    

 

		(A)	Commercial general liability insurance naming Landlord, Landlord’s management agents and Landlord’s Mortgagee(s) from
time to time as additional insureds, with coverage for premises/operations, personal injury, and contractual liability with combined single
limits of liability of not less than $6,000,000 for bodily injury and property damage per occurrence and $7,000,000 in the aggregate.

 

		(B)	Property insurance covering property damage and business interruption. Covered property shall include all tenant improvements in the
Premises (including any Tenant Work) and Tenant’s Property. Such insurance, shall name Landlord and Landlord’s Mortgagees
from time to time as loss payees as their interests may appear. Such insurance shall be written on an “all risk” of physical
loss or damage basis including the perils of fire, extended coverage, windstorm, vandalism, and malicious mischief, and such other risks
Landlord may from time to time designate (provided that insurance for such other risks is then being provided by similar types of tenants
in the greater Boston area under leases of similar types of premises), for the full replacement cost value of the covered items and in
amounts that meet any co-insurance clause of the policies of insurance, with a deductible amount not to exceed a then- commercially reasonable
deductible, which initially shall be no greater than $100,000.

 

		(C)	Workers’ compensation insurance with statutory benefits and employers’ liability insurance in the following amounts: each
accident, $500,000; disease (policy limit), $500,000; disease (each employee), $500,000.

 

		(D)	During all construction by Tenant, Tenant shall maintain with respect to the Premises and Property adequate builder’s risk covering
the cost of replacing all such construction, and Landlord its mortgagees shall be named as loss payees as their interests may appear).

 

On or before the Term Commencement Date and upon renewal, Tenant shall
give Landlord certificate(s) evidencing the liability, builder’s risk, workers’ compensation insurance and property insurance
on Tenant’s Property evidencing such coverages, and stating that such insurance may not be canceled without at least thirty (30)
days’ prior written notice to Landlord. Liability insurance maintained by Tenant with respect to the Premises shall be deemed to
be primary insurance, and any liability insurance maintained by Landlord with respect to the Premises shall be deemed secondary to it.

 

Such insurance may be provided by a combination
of underlying general liability insurance coverage and umbrella excess liability insurance. The risk of loss to all contents of, and personal
property and trade fixtures located in the Premises is upon the Tenant, and the Landlord shall have no liability with respect thereto,
except for that due solely to the negligence of Landlord or its agents, contractors or employees.

 

Landlord shall maintain the following throughout
the Term with companies licensed and approved to write insurance in the state in which the Building is located:

 

    14 

     

    

 

		(A)	property insurance against direct physical loss or damage to the Building (and parking areas to the extent such parking areas can
customarily be insured against casualty) on an “all risks,” agreed amount basis in an amount equal to the physical replacement
cost of the Building (and, if applicable, parking areas). Landlord shall not be required to carry insurance with respect to any property
that Tenant is required to insure pursuant to this Lease;

 

		(B)	liability insurance against claims, demands or actions for injury, death, and property damage in amounts not less than Five Million
Dollars ($5,000,000) in the aggregate; and

 

		(C)	reasonable rental loss insurance.

 

The Landlord and the Tenant each hereby waive all
rights against the other and release the other from any liability for any loss or damage to the Building, the Premises or other property
and whether or not caused by the negligence or other fault of the Landlord, the Tenant or their respective agents, employees, subtenants,
licensees, invitees or assignees; provided, however, that this waiver and release (i) shall apply notwithstanding the indemnities set
forth in Section 13, but only to the extent that such loss or damage to the Building or other property is covered by insurance which
protects the releasing or waiving party; (ii) shall not be construed to impose any other or greater liability upon either the Landlord
or the Tenant than would have existed in the absence hereof; and (iii) shall be in effect only to the extent and so long as the applicable
insurance policies provide that this release shall not affect such policies or the right of the insureds to recover under such policies,
which clauses shall be obtained by the parties hereto whenever reasonably available.

 

Each party shall provide to the other within ten
(10) days of execution of this Lease insurance certificates evidencing compliance with this Section and periodically thereafter upon
reasonable request. Any failure of Tenant to carry the required insurance shall constitute a default hereunder and shall also impose on
Tenant the obligations of a self-insurer to the extent of any such failure.

 

		8.	Electricity; Telecommunications and Other Utilities.

 

Landlord has furnished electrical service as
presently installed in the Building for the operation of lighting fixtures, and 120 volt current for the operation of normal office
fixtures and equipment, but excluding any high energy consumption equipment. Tenant will be allowed Tenant’s Pro Rata Share of
the electrical capacity of the Building (which is set forth on the attached Exhibit B). Landlord shall, at
Landlord’s expense, install an electrical checkmeter to measure Tenant’s consumption of electricity. From and after the
Term Commencement Date, Tenant shall pay to Landlord monthly as Additional Rent an amount equal to the actual number of kilowatt
hours of electrical service provided to the Premises, multiplied by the average rate per kilowatt hour paid by Landlord for the
Building. Tenant shall make such monthly payments in an amount reasonably estimated by Landlord based on invoices received by
Landlord from the applicable service provider. Landlord may from time to time revise such estimates based on available information
relating to or otherwise affecting the cost of the electrical services provided to the Premises. The difference, if any, between the
amount so paid by Tenant and the actual cost of electricity used by Tenant shall be adjusted not less than annually in the manner
set forth in Section 6.3 above for the annual adjustment of Additional Rent for Operating Expenses and Taxes.

 

Tenant agrees never to overload the electrical
service and to be solely responsible for the consequences of any overloading, indemnifying and holding Landlord harmless with respect
thereto in the manner provided for in Section 13 of this Lease. Tenant shall also be responsible for arranging for and paying all
costs associated with telecommunications and any other utility or service required by Tenant (other than water and sewage for bathrooms
and drinking fountains, which Landlord shall arrange for as an element of Landlord’s Operating Expenses).

 

    15 

     

    

 

		9.	Tenant’s Repairs and Maintenance; Security.

 

From and after the Term Commencement Date throughout
the Term, the Tenant shall, at its own cost and expense: (i) make interior repairs, replacements and renewals necessary to keep the Premises
and all equipment and appurtenances, including all systems, pipes, ducts, conduits and wires wherever located either within or, with Landlord’s
prior approval, outside of the Premises from the point where the same begin to exclusively serve the Premises, in good order, condition
and repair consistent with the condition of the Premises at the commencement of the Term or as they thereafter may be put, reasonable
wear and use (damage by fire or other casualty or taking being elsewhere provided for) and Landlord’s express obligations under
this Lease only excepted (it being understood, however, that the foregoing exception for reasonable wear and use shall not relieve the
Tenant from the obligation to keep the Premises in good order, repair and condition), (ii) make all other repairs, replacements and renewals
which are required due to the negligence or misconduct of the Tenant or those acting under Tenant or are expressly provided for elsewhere
in this Lease, and (iii) keep and maintain all portions of the Premises in a reasonably clean and orderly condition, free of accumulation
of dirt, rubbish, and other debris. The foregoing shall include without limitation Tenant’s obligation to maintain and repair floors,
floor coverings and all mechanical, plumbing, electrical and other systems and equipment that exclusively serve the Premises wherever
located (whether or not the same are located inside or outside the Premises), to paint and repair walls and doors, to replace and repair
ceiling tiles, interior glass (and exterior glass if such damage or repair is necessitated by any act of Tenant or person acting under
Tenant), lights and light fixtures, drains, water heaters and the like, and regularly to clean the Premises. Notwithstanding the foregoing,
Landlord shall provide all Building heating, ventilation and air condition (“HVAC”) systems; plumbing, including water supply
and drainage systems; and mechanical, electrical, lighting and life safety systems servicing the Premises in good working order on the
Term Commencement Date. If any of the foregoing systems fail and need to be replaced during the Initial Term, Landlord will pay for the
capital cost of replacing the system and shall amortize such cost over the useful life of the replacement system in accordance with GAAP
and shall recover such cost as part of Landlord’s Operating Expense.

 

Tenant shall be responsible for securing its Premises
including implementing all security measures with respect to access thereto. Tenant shall also be responsible, on a nightly basis, for
removal of trash and other rubbish from its Premises to the common area dumpsters.

 

    16 

     

    

 

All personal property of any person which is located
on or near the Premises shall be at the sole risk of Tenant and subject to the insurance requirements set forth in Section 7. Landlord
shall not be liable for any loss or damage to person or property resulting from any accident, theft, vandalism or other occurrence on
or to the Premises, including damage resulting from water, wind, ice, steam, explosion, fire, smoke, chemicals, the rising of water or
leaking or bursting of pipes or sprinklers, defect, structural or non-structural failure or any other cause except to the extent such
loss or damage is caused solely and directly by Landlord’s negligence.

 

		10.	Landlord’s Services

 

10.1         
Building Common Services. Landlord shall provide the services set forth in this Section 10. Landlord shall have no
obligation to provide any service to the Building, Premises or Tenant that is not expressly set forth in this Lease. Without limiting
the generality of the previous sentence, Tenant acknowledges and agrees that as an accommodation to Tenant and other users of the Building
the central plant of the Building is used as of the date hereof to provide comfort cooling.

 

10.1.1   
Water Charges. Landlord shall furnish potable water for ordinary office cleaning, toilet, kitchen, lavatory and drinking
purposes. Landlord shall install a meter to measure the use of any such water. From and after the Term Commencement Date, Tenant shall
pay to Landlord monthly as Additional Rent an amount equal to the actual amount of water provided to the Premises, multiplied by the average
rate per gallon paid by Landlord for the Building. Tenant shall make such monthly payments in an amount reasonably estimated by Landlord
based on invoices received by Landlord from the applicable service provider. Landlord may from time to time revise such estimates based
on available information relating to or otherwise affecting the cost of the water provided to the Premises. The difference, if any, between
the amount so paid by Tenant and the actual cost of water used by Tenant shall be adjusted not less than annually in the manner set forth
in Section 6.3 above for the annual adjustment of Additional Rent for Operating Expenses and Taxes.

 

10.1.2   
Cleaning. Landlord shall cause the common areas of the Building to be kept reasonably clean.

 

10.1.3   
Other Building Services. Landlord will through the existing Building systems furnish those Building services at the capacities
and in accordance with Exhibit B. Tenant will be allowed Tenant’s Pro Rata Share of such Building services, and Tenant
will not exceed its Pro Rata Share. Landlord will furnish the house meter for such services and Tenant will furnish appropriate metering
for its consumption of such services.

 

10.1.4   
Cafeteria. Landlord shall cause a full service cafeteria to be provided at the Building which will be generally consistent
with the current cafeteria’s size, scope and service.

 

    17 

     

    

 

10.1.5    Common
Areas. Landlord shall light and maintain the common lobbies and related areas of the Building on business days (meaning any day
of the week other than Saturday, Sunday, or a day on which banking institutions in Boston, Massachusetts or in the city in which the
Property is located are obligated or authorized by law or executive action to be closed to the transaction of normal banking
business) during normal business hours of 7:00 a.m. to 6:00 p.m. Notwithstanding such hours for such common areas, Tenant shall have
access to the Premises on a 24 hours per day, 7 days per week basis, Tenant being responsible for providing pass cards and all
security with respect to the Premises (and Landlord shall provide card access for Building perimeter doors).

 

10.2         
Repairs and Maintenance. Except for repairs to items necessitated by Tenant’s or other tenants in the Building act,
neglect or overloading or the act, neglect or overloading of persons acting under Tenant (which shall be Tenant’s or the other tenant’s
sole responsibility), Landlord shall, as expenses included in Landlord’s Operating Expenses, make such repairs to the roofs, exterior
walls, exterior windows of the Premises, floor slabs, core walls, and common areas and facilities in the Building (including, without
limitation, the Building’s mechanical, electrical, common area lighting, plumbing and life safety systems) as may be necessary to
keep them in good order, condition and repair consistent with the condition at the commencement of the Term or as they thereafter may
be put (except that the costs to replace the roof, foundation or structural frame of the Building during the Initial Term shall not be
included in Landlord’s Operating Expenses charged to Tenant). In addition, Landlord shall, as expenses included in Landlord’s
Operating Expenses, make improvements, alterations and additions to the Building which are directed by public authorities in order to
render the same in compliance with laws, rules and directives, including the provisions of the Americans with Disability Act (“ADA”)
applicable to the Building common areas (but Tenant shall be responsible for compliance with the ADA applicable to the interior of the
Premises or on account of its use of the Premises) as in effect and generally enforced as of the Term Commencement Date. For avoidance
of doubt, Landlord shall have no maintenance, repair, replacement or other responsibility in connection with Tenant’s obligations
set forth under Section 9.

 

		11.	Compliance with Laws and Regulations

 

The Tenant agrees that its obligations to make
payment of Basic Rent, Additional Rent and all other charges on its part to be paid, and to perform all of the covenants and agreements
on its part to be performed during the Term hereunder shall not, except as herein set forth in the event of condemnation by public authority
(which shall be subject to Section 15 below), be affected by any present or future law, by-law, ordinance, code, rule, regulation,
order or other lawful requirement regulating or affecting the use which may be made of the Premises.

 

During the Term the Tenant shall comply, at its
own cost and expense, with all applicable laws, by-laws, ordinances, codes, rules, regulations, orders, and other lawful requirements
of the governmental bodies having jurisdiction, foreseen or unforeseen, which are applicable to the Premises or the fixtures and equipment
therein and thereon, including, without limitation, OSHA requirements, ADA and handicap access requirements applicable to the interior
of the Premises or on account of Tenant’s use thereof, fire, building and safety codes; the orders, rules and regulations of the
National Board of Fire Underwriters, or any other body hereafter constituted exercising similar functions, which may be applicable to
the Premises, the fixtures and equipment therein or thereon or the use thereof; and the requirements of all policies of public liability,
fire and all other types of insurance at any time in force with respect to the Premises, the Building or the Property and the fixtures
and equipment therein and thereon.

 

    18 

     

    

 

		12.	Landlord’s Access

 

The Tenant agrees to permit the Landlord and any
Mortgagees and their authorized representatives to enter the Premises (i) at all reasonable times and upon reasonable advance notice during
usual business hours for the purposes of inspecting the same, exercising such other rights as it or they may have hereunder or under any
mortgages and exhibiting the same to other prospective tenants, purchasers or mortgagees, and (ii) at any time in the event of emergency.
Landlord will comply with reasonable security measures (and Landlord acknowledges that any such measures imposed by a governmental authority
shall be reasonable for purposes of this Section) of which Landlord is provided written notice from Tenant so long as the same comply
with the terms of this Lease, including, without limitation, this Section; provided that in all instances Landlord shall be permitted
access to the Premises (w) in the event of an emergency, (x) as required or permitted in order for Landlord to perform its obligations
or exercise its rights under this Lease, (y) as required by applicable law or (z) otherwise in response to specific requests by Tenant
and in accordance with a schedule reasonably designated by Tenant, subject to Landlord’s reasonable approval.

 

		13.	Indemnity

 

Subject to the rights expressly reserved to Landlord,
Tenant shall assume exclusive control of the Premises and all areas pertaining thereto including all appurtenances, improvements and equipment,
and Tenant shall bear the sole risk of all related tort liabilities. Tenant agrees to protect, defend (with counsel reasonably approved
by the Landlord), indemnify and save the Landlord and its Mortgagees harmless from and against any and all claims and liabilities arising
(i) from the conduct or management of or from any work or thing whatsoever done in or about the Premises during the Term and from any
condition existing, or any injury to or death of persons or damage to property occurring or resulting from an occurrence during the Term
in or about the Premises, except for any such matter as shall arise from or due to the negligence or willful misconduct of Lessor or Lessor’s
employees, officers, members, agents or contractors, and (ii) from any breach or default on the part of the Tenant in performance of any
covenant or agreement on the part of the Tenant to be performed pursuant to the terms of this Lease or from any negligent act or omission
on the part of the Tenant or any of its agents, employees, subtenants, licensees, invitees or assignees. The Tenant further agrees to
indemnify the Landlord from and against all costs, expenses (including reasonable attorneys’ fees) and other liabilities incurred
in connection with any such indemnified claim or action or proceeding brought thereon, any and all of which, if reasonably suffered, paid
or incurred by the Landlord, the Tenant shall pay promptly upon demand to the Landlord as Additional Rent. Landlord shall give Tenant
prompt written notice of any such claim. Tenant may defend such claim with counsel reasonably approved by Landlord. Without limiting in
any way this indemnity and hold harmless agreement, Tenant shall have the right to settle claims for which Tenant is to indemnify and
hold Landlord harmless without first obtaining a consent of Landlord to such settlement on the condition that Landlord shall incur no
costs, expense, liability or damage on account of such settlement whatsoever.

 

The provisions of this Section shall expressly
survive expiration or the earlier termination of the Lease.

 

    19 

     

    

 

 

	14.	Casualty Damage

 

If through no act or neglect of Tenant or persons
acting under Tenant the Premises or any part thereof shall be damaged by fire or other insured casualty, then, subject to the following
provisions of this Section, Landlord shall proceed with diligence, subject to then applicable laws and at the expense of Landlord (but
only to the extent of insurance proceeds received and made available to Landlord by any Mortgagee) to cause to be repaired such damage,
excluding any items installed or paid for by Tenant which Tenant is permitted or required to remove upon expiration of the Term (which
items shall be Tenant’s responsibility to repair). However, if any damage occurs through the act or neglect of Tenant or persons
acting under Tenant or if any act or neglect of Tenant or such persons prevents Landlord or its Mortgagees from collecting all insurance
proceeds, then the cost of repairing the casualty damage shall be paid by Tenant except to the extent any insurance proceeds are actually
received by Landlord or Mortgagees (they being under no obligation to litigate their entitlement), and there shall be no abatement of
rent.

 

Subject to the foregoing, in the event of partial
or total destruction of the Premises during the Term by fire or other casualty, the Landlord shall, as promptly as practicable after receipt
of any insurance proceeds available as a result of such casualty, repair, reconstruct or replace the portions of the Premises destroyed
as nearly as possible to their condition prior to such destruction, except that in no event shall the Landlord be obligated to expend
more for such repair, reconstruction or replacement than the amounts of any such insurance proceeds actually received plus the amount
of the deductible, if any, applicable to Landlord’s insurance coverage. The adjustment of any insurance loss shall be controlled
by the Landlord provided that the Tenant shall reasonably cooperate with Landlord in all such activity. Commencing on the date of such
casualty and during the period of such repair, reconstruction and replacement there shall be an equitable abatement of Basic Rent and
Additional Rent hereunder from the date of such casualty in proportion to the loss of usable floor area in the Premises but only to the
extent such abatement is covered by lost rentals insurance for the benefit of the Landlord. Without limiting the foregoing, the parties
agree that such abatement shall be provided ratably to the extent portions of the Premises or parking areas shall be untenantable as a
result of any damage or destruction, or any failure of Landlord to provide access to the Premises as a result of any such damage or destruction,
or if there is an interruption of essential services provided by Landlord as a result of any such damage or destruction, for more than
five (5) consecutive business days, or such lesser period if covered when lost rentals insurance applies, then the Basic Rent and Additional
rent and any other amounts owed by Tenant to Landlord as rent shall be proportionally abated and shall not be payable with respect to
such affected portion from the date of such interruption until such services or access have been restored or such damage or destruction
has been repaired to such affected portion (but Tenant shall continue to pay all rent on the remaining portion of the Premises). Tenant’s
entry into the Premises to remove Tenant’s personal property during such interruption of essential services shall not be deemed
as use of the Premises and such entry shall not effect any abatement of rent.

 

    20 

     

    

 

If the Building or Premises
are so extensively destroyed by fire or other casualty that an independent engineer or architect engaged by the Landlord certifies
to Landlord (which certification shall be final and binding on the parties) that either cannot reasonably be expected to be
susceptible of repair, reconstruction or replacement for the amount of insurance proceeds available or that such restoration, repair
or replacement cannot be completed within a period of six (6) months from the date work were to commence thereon, or if any damage
results from causes or risks not required to be insured against hereunder or if any Mortgagee refuses to make such net proceeds
available for such repair, reconstruction or replacement, then in any such case Landlord may terminate this Lease by giving written
notice to the Tenant within thirty (30) days after the date of such certification. If either (x) such repair, restoration or
replacement shall not be commenced within six (6) months after the date of such fire or other casualty or (y) Landlord having
commenced shall, subject always to Section 31, thereafter fail diligently to prosecute the same to completion, Tenant shall
have the right after the occurrence of any such event to terminate this Lease by giving Landlord (and any Mortgagee) at least sixty
(60) days prior written notice of its intent to do so. This Lease shall terminate sixty (60) days after the date of such notice to
Landlord and Mortgagee, unless Landlord as the case may be commences such repair, replacement or restoration or resumes diligent
prosecution of the same within said sixty (60)-day day period. All of the foregoing time periods shall be extended for any Force
Majeure delays. Furthermore, notwithstanding anything contained in this Lease to the contrary, if any such fire or other casualty
occurs at such time that there is less than twelve (12) months remaining in the Term of this Lease (after giving effect to any
extension option actually exercised by the Tenant and not subject to any condition to its effectiveness) then the Landlord shall
have no obligation hereunder if the Premises cannot reasonably be expected to be susceptible of repair, reconstruction or
replacement for the amount of insurance proceeds available or if such restoration, repair or replacement cannot be completed within
a period of ninety (90) days from the date work were to commence thereon.

 

	15.	Condemnation

 

If more than 33% of the usable floor area of the
Premises is taken by eminent domain or appropriation by public authority or if the Tenant shall be deprived of suitable vehicular or pedestrian
access to the Premises or the Property by virtue of such a taking or appropriation, then Landlord or the Tenant may terminate this Lease
by giving written notice to the other within thirty (30) days after such taking or appropriation. In the event of such a termination,
this Lease shall terminate as of the date the Tenant must surrender possession or, if later, the date the Tenant actually surrenders possession,
and the Basic Rent and Additional Rent reserved shall be apportioned and paid to and as of such date.

 

If all or any part of the
Premises is taken or appropriated by public authority as aforesaid and this Lease is not terminated as set forth above, the Landlord
shall, subject to the rights of any Mortgagees, proceed on a commercially reasonable basis, apply any such damages and compensation
awarded (net of the costs and expenses, including reasonable attorneys’ fees, incurred by the Landlord in obtaining the same)
to secure and close so much of the Premises as remain and shall restore the Building to an architectural whole and except that in no
event shall the Landlord be obligated to expend more for such replacement than the net amount of any such damages, compensation or
award which the Landlord may have received as damages in respect of the Building and any other improvements situated on the Property
as they existed immediately prior to such taking or appropriation; in such event there shall be an equitable abatement of Basic Rent
in proportion to the loss of usable floor area in the Premises after giving effect to such restoration, from and after the date the
Tenant must surrender possession or, if later, the date the Tenant actually surrenders possession. If this lease is not terminated
as set forth above and either (x) such repair, restoration or replacement undertaken by Landlord shall not be commenced within six
(6) months after the date of such taking or (y) Landlord having commenced shall thereafter fail diligently to prosecute the same to
completion, Tenant shall after the occurrence of any such event have the right to terminate this Lease by giving Landlord (and any
Mortgagee) at least sixty (60) days prior written notice of its intent to do so. This Lease shall terminate sixty (60) days after
the date of such notice to Landlord and any Mortgagee, unless Landlord as the case may be commences such repair, replacement or
restoration or resumes diligent prosecution of the same within said sixty (60)-day day period. All of the foregoing time periods
shall be extended for any Force Majeure delays. Furthermore, notwithstanding anything contained in this Lease to the contrary, if
any such taking occurs at such time that there is less than twelve (12) months remaining in the Term of this Lease (after giving
effect to any extension option actually exercised by the Tenant and not subject to any condition to its effectiveness) then the
Landlord shall have no obligation hereunder if the Premises cannot reasonably be expected to be susceptible of repair,
reconstruction or replacement for the amount of taking award available or if such restoration, repair or replacement cannot be
completed within a period of ninety (90) days from me date work were to commence thereon.

 

    21 

     

    

 

The Landlord hereby reserves, and the Tenant hereby
assigns to the Landlord, any and all interest in and claims to the entirety of any damages or other compensation by way of damages which
may be awarded in connection with any such taking or appropriation, except so much of such damages or award as is specifically and separately
awarded to the Tenant and expressly attributable to trade fixtures or moving expenses of the Tenant.

 

	16.	Landlord’s Covenant of Quiet Enjoyment; Title; Mutual Authority

 

The Landlord covenants that the Tenant, upon paying
the Basic Rent and Additional Rent provided for hereunder and performing and observing all of the other covenants and provisions hereof,
may peaceably and quietly hold and enjoy the Premises for the Term as aforesaid, subject, however, to all of the terms and provisions
of this Lease and all easements, restrictions, agreements, and encumbrances of record to the extent in force and applicable. This covenant
is in lieu of any other so-called quiet enjoyment covenant, whether express or implied.

 

The Landlord and Tenant each represent and warrant
to the other that each has full right, power and authority to enter into, perform and grant to the other all of the rights set forth in
this Lease.

 

	17.	Tenant’s Obligation to Quit

 

The Tenant (and all persons
claiming under Tenant) shall, upon expiration of the Term or other termination of this Lease, leave and peaceably and quietly surrender
and deliver to the Landlord the Premises and any replacements or renewals thereof in the order, condition and repair required of Tenant
by any provisions of this Lease, except, however, that the Tenant shall (A) remove any trade fixtures, equipment and personal property,
whether or not bolted or attached (including any such fixtures, equipment and personal property on the Term Commencement Date); (B) remove
all of Tenant’s signs wherever located; (C) remove any Removal Items that Landlord has required be removed pursuant to the terms
of Section 3 hereof; (D) repair all damage which results from such removal, including the filling of all floor and wall holes,
and the replacement of all damaged ceiling tiles; and (E) shall restore all portions of the Premises so damaged by Tenant’s removal
to a fully functional and tenantable condition, reasonable wear and tear and damage by taking and fire or casualty excepted. If the Tenant
shall fail so to perform the foregoing, any property shall be deemed abandoned by the Tenant, and the Landlord may remove and dispose
of the same and perform Tenant’s obligations at the Tenant’s expense, which covenant by Tenant to pay the same shall survive
the expiration or earlier termination of this Lease.

 

If Tenant remains in the Premises after the termination
or expiration of the Term such holding over shall be as a tenant at sufferance at a rent equal to one hundred fifty (150%) of the Basic
Rent due hereunder for the last month of the Term, and otherwise subject to all the covenants and conditions of this Lease including obligations
to pay Additional Rent. Notwithstanding the foregoing provisions of this paragraph, if Landlord desires to regain possession of the Premises
in such event, Landlord may, at its option, re-enter and take possession of the Premises or any part thereof at any time thereafter or
by any legal process in force in the state in which the Premises are located and exercise any other right or remedy permitted to it by
law, and Tenant shall save Landlord harmless, indemnify and defend Landlord against any claim, loss, cost or expense in the manner elsewhere
provided for in this Lease arising out of Tenant’s failure promptly to vacate the Premises or any portion thereof, expressly including
without limitation any damages Landlord suffers because of any termination of, or penalty amounts paid under, any successor leases of
all or portions of the Premises.

 

The provisions of this Section shall expressly
survive the termination or expiration of this Lease.

 

    22 

     

    

 

	18.	Transfers of Tenant’s Interest

 

Tenant, voluntary or
involuntarily, shall not assign this Lease, or sublet, license, mortgage or otherwise encumber or convey the Premises or any portion
thereof, or permit the occupancy of all or any portion of the Premises other than by the Tenant (all or any of the foregoing actions
are referred to as “Transfers”, and all or any of assignees, transferees, licensees, and other such parties are referred
to as “Transferees”) without obtaining, on each occasion, the prior written consent of the Landlord, which consent shall
not be unreasonably withheld, conditioned or delayed. Any Transfer without such consent shall be null and void and of no effect
whatsoever. Notwithstanding the provisions of this Section, this Lease may be assigned, or the Premises may be sublet, in whole or
in part, after prior notice to Landlord and compliance with the following procedures but without consent of the Landlord, (i) to any
entity into or with which Tenant may be merged or consolidated or to any entity to which all or substantially all of the
Tenant’s assets will be transferred, or (ii) to any entity which is an affiliate, subsidiary, parent or successor of Tenant or
Tenant’s parent, or in which Tenant or Tenant’s parent has a controlling interest, provided that in all such cases the
Transferee surviving or affiliate Transferee entity shall (a) agree in writing with the Landlord to be bound by all of the terms and
conditions of this Lease and (b) shall have a net worth reasonably equivalent to Tenant’s net worth as of the Term
Commencement Date (all of the foregoing being referred to as a “Permitted Transfer”). Tenant shall not offer to make or
enter into negotiations with respect to a Transfer to any of the following: (i) a tenant in the Building; (ii) any person with whom
Landlord is negotiating with respect to space in the Building; or (iii) any person which would be of such type, character or
condition, including financial condition, as to be inappropriate, in Landlord’s reasonable judgment, as a tenant for a first
class office/manufacturing building. Tenant’s request for consent to a Transfer shall include a copy of the proposed Transfer
instrument together with a statement of the proposed Transfer in detail satisfactory to Landlord, together with reasonably detailed
financial, business and other information about the proposed Transferee. If at any time during the final two (2) Lease Years of the
Term Tenant proposes to Transfer all or any portion of the Premises and such Transfer is not a Permitted Transfer, then Tenant shall
provide Landlord with written notice of its intention to do so and Landlord shall have the option (but not the obligation) to
terminate the Lease with respect to all or such portion of the Premises proposed to be Transferred effective upon a date designated
by Landlord that is no less than sixty (60) days but no more than ninety (90) days after Landlord receives such notice from Tenant
and such termination shall continue for the remainder of the Term. Landlord shall exercise such termination right by giving Tenant
notice of such termination (which shall include Landlord’s designated effective termination date) within thirty (30) days
after Landlord’s receipt of such proposal from Tenant. If Landlord elects so to terminate this Lease with respect to all or
such portion of the Premises proposed to be Transferred, then the parties shall reasonably execute an amendment to this Lease giving
effect to such election. If Tenant makes a Transfer hereunder (other than a Permitted Transfer) and Landlord does not so elect to
terminate this Lease with respect to all or such portion of the Premises to be Transferred, and if the aggregate rent and other
charges payable to Tenant under and in connection with such Transfer (including without limitation any amounts paid for leasehold
improvements or on account of Tenant’s costs associated with such Transfer) exceed the sum of (x) all rent and other charges
paid hereunder with respect to the space in question and (y) Tenant’s reasonable out-of-pocket costs to procure the Transfer,
including but not limited to free rent, brokerage commissions, tenant improvement costs and legal fees amortized on a straight-line
basis over the term of the Transfer, Tenant shall pay to Landlord, as Additional Rent, fifty percent (50%) of the amount of such
excess. If the amount of rent and other charges payable under a Transfer is not readily ascertainable, such amount may, at
Landlord’s option, be deemed to equal the fair market rent then obtainable for the space in question.

 

In all events including Permitted Transfers the
Tenant originally named herein shall remain primarily and jointly and severally liable for, and any sublessee of all or substantially
all of the Premises and assignee shall in writing assume, the obligations of the Tenant under this Lease. The foregoing provision shall
be self-operative, but in confirmation thereof, such Transferee shall execute and deliver such instruments as may be reasonably required
by Landlord to acknowledge such liability. Landlord may collect Rent from the Transferee and apply the net amount collected to the Rent
and other charges hereunder (but only in the event of Tenant default), but no such assignment or collection shall be deemed a waiver of
the provisions of this Section, or the acceptance of the Transferee as a tenant, or a release of Tenant from direct and primary liability
for the further performance of Tenant’s covenants hereunder. The consent by Landlord to a particular Transfer shall not relieve
Tenant from the requirement of obtaining the consent of Landlord to any further Transfer. The consent by Landlord to any Transfer shall
not relieve Tenant from the obligation of obtaining the express consent of Landlord to any modification of such Transfer or a further
Transfer; nor shall Landlord’s consent alter in any manner whatsoever the terms of this Lease, to which any Transfer at all times
shall be subject and subordinate. Failure by Landlord to consent to a proposed Transferee shall never cause a termination of this Lease
or subject Landlord to any damages beyond Tenant’s direct costs of establishing its entitlement to such consent.

 

    23 

     

    

 

The Tenant shall reimburse to the Landlord as Additional
Rent, upon demand, for any reasonable costs in an amount up to $2,500 that may be incurred by the Landlord in connection with any proposed
Transfer (other than a Permitted Transfer) any request for consent thereto, including without limitation the costs of making investigations
as to the acceptability of any proposed assignee or subtenant, and reasonable attorneys’ fees.

 

	19.	Transfers of Landlord’s Interest

 

The Landlord shall have the right from time to
time to sell or mortgage its interest in the Property, the Building and the Premises, to assign its interest in this Lease, or to assign
from time to time the whole or any portion of the Basic Rent, Additional Rent or other sums and charges at any time paid or payable hereunder
by the Tenant to the Landlord, to any Mortgagees or other transferees designated by the Landlord in duly recorded instruments, and in
any such case the Tenant shall pay the Basic Rent, Additional Rent and such other sums and charges so assigned, subject to the terms of
the Lease, upon demand in writing to such Mortgagees and other transferees at the addresses mentioned in and in accordance with the terms
of such instruments.

 

	20.	Mortgagees’ Rights

 

Landlord agrees that within ten (10) days after
the execution of this Lease, Landlord shall cause its Mortgagee to execute and deliver a subordination, non-disturbance and attornment
agreement substantially in the form of Exhibit D hereto or on such Mortgagee’s then-standard form. The Tenant hereby
agrees that this Lease is and shall be subject and subordinate to any mortgage (and to any amendments, extensions, increases, refinancings
or restructurings thereof) of the Property, the Building or the Premises, filed subsequent to the execution, delivery or the recording
of any notice of this Lease (the holder from time to time of any such mortgage, including the present holder of the existing mortgage,
being sometimes called the “Mortgagee”). Notwithstanding the foregoing, such subordination shall only be effective so long
as any Mortgagee executes a subordination, non-disturbance and attornment agreement (or equivalent document) in the form attached as Exhibit D
or such other form as Tenant and any such Mortgagee may reasonably agree upon. The Tenant hereby agrees to execute, acknowledge and deliver
in recordable form such instruments confirming and evidencing the foregoing subordination in the form of agreement attached hereto as
Exhibit D or such other form as Tenant and any such Mortgagee may reasonably agree upon. If Tenant fails to execute and deliver
such instrument within ten (10) days of receipt from Landlord, Tenant hereby grants to Landlord and its designees a power-of-attorney
coupled with an interest and with full power of substitution to execute, acknowledge and deliver such instrument in the name and on behalf
of Tenant with the same effect as if such action had been taken by Tenant.

 

    24 

     

    

 

Provided that the Tenant
has been provided with notice of such mortgage and appropriate addresses to which notice should be sent, no notice from the Tenant
of any default by the Landlord in its obligations shall be valid, and the Tenant shall not attempt to terminate this Lease, withhold
Basic Rent or Additional Rent or exercise any other remedy which may arise under law by reason of such default (it being understood
that no such remedy exists, or is implied by reason of this provision, under this Lease) unless the Tenant first gives such notice
to any Mortgagees and provides such Mortgagees with thirty (30) days after such notice to cure such default, or if such default is
not reasonably susceptible of cure by Mortgagees (as in the case of the need to obtain possession of or right of entry into or upon
the Premises) in thirty (30) days, with such longer period of time as is reasonably necessary to cure such default, provided efforts
to effectuate such cure are commenced within thirty (30) days and thereafter prosecuted to completion with reasonable diligence. The
Tenant shall and does hereby agree, upon default by the Landlord under any mortgage, to attorn to and recognize the Mortgagee or
anyone else claiming under such mortgage, including a purchaser at a foreclosure sale, at its request as successor to the interest
of the Landlord under this Lease, to execute, acknowledge and deliver such evidence of this attornment, which shall nevertheless be
self-operative and automatically effective, as the Mortgagee or such successor may reasonably request and to make payments of Basic
Rent and Additional Rent hereunder directly to the Mortgagee or any such successor, as the case may be, upon written request, but
subject to the provisions of any applicable subordination, non-disturbance and attornment agreement. Any Mortgagee may, at any time,
by giving written notice to, and without any further consent from, the Tenant, subordinate its mortgage to this Lease, and thereupon
the interest of the Tenant under this Lease shall automatically be deemed to be prior to the lien of such mortgage without regard to
the relative dates of execution, delivery or filing thereof or otherwise.

 

	21.	Default; Remedies

 

If Tenant shall default in the payment when due
of any Basic Rent or Additional Rent, and such default shall continue for five (5) business days after written notice thereof from Landlord,
or if Tenant shall default more than twice in any twelve (12) month period in the payment when due of any Basic Rent or Additional Rent
and such default shall continue for five (5) days (without the requirement for any written notice thereof from Landlord), or if Tenant
shall default in the timely performance or observance of any of the other covenants contained in this Lease on the Tenant’s part
to be performed or observed and shall fail, within thirty (30) days after written notice from Landlord of such default, to cure such default
or if such default is not reasonably susceptible of cure within thirty (30) days, if Tenant shall fail to commence to cure within said
thirty (30) days after notice of such default from Landlord or shall thereafter fail with reasonable diligence to prosecute such cure
to completion, or if Tenant vacates substantially all of the Premises, or if Tenant (or any Transferee of Tenant) makes any transfer of
the Premises in violation of this Lease, or if the estate hereby created shall be taken on execution, or by other process of law, or if
with respect to Tenant or any guarantor or Transferee of Tenant:

 

		(1)	by its commencement of a voluntary case under Title 11 of the United States Code as from time to time in effect, or by its authorizing,
by appropriate proceedings of trustees or other governing body the commencement of such a voluntary case,

 

		(2)	by its filing an answer or other pleading admitting or failing to deny the material allegations of a petition filed against it commencing
an involuntary case under said Title 11, or seeking, consenting to or acquiescing in the relief therein provided, or by its failing to
controvert timely the material allegations of any such petition,

 

		(3)	by the entry of an order for relief in any involuntary case commenced under said Title 11,

 

    25 

     

    

 

		(4)	by its seeking relief as a debtor under any applicable law, other than said Title 11, of any jurisdiction relating to the liquidation
or reorganization of debtors or to the modification or alteration of the rights of creditors, or by its consenting to or acquiescing in
such relief,

 

		(5)	by the entry of an order by a court of competent jurisdiction (i) finding it to be bankrupt or insolvent, (ii) ordering or approving
its liquidation, reorganization or any modification or alteration of the rights of its creditors, or (iii) assuming custody of, or appointing
a receiver or other custodian for, all or a substantial part of its property, or

 

		(6)	by its making an assignment for the benefit of, or entering into a composition with, its creditors, or appointing or consenting to
the appointment of a receiver or other custodian for all or a substantial part of its property;

 

then and in any of said cases, the Landlord may, to the extent permitted
by law, immediately or at any time thereafter and without demand or notice, terminate this Lease and enter into and upon the Premises,
or any part thereof in the name of the whole, and repossess the same as of the Landlord’s former estate, and expel the Tenant and
those claiming through or under the Tenant and remove its and their effects without being deemed guilty of any manner of trespass, and
without prejudice to any remedies which might otherwise be used for arrears of rent or preceding breach of covenant.

 

Tenant waives any statutory notice to quit and
equitable rights in the nature of further cure or redemption, and Tenant agrees that upon Landlord’s termination of this Lease Landlord
shall be entitled to re-entry and possession in accordance with the terms hereof. Tenant further agrees that it shall not interpose any
counterclaim in any summary proceeding or in any action based in whole or in part on non-payment of Rent unless the counterclaim is a
compulsory counterclaim that must be alleged in the same proceeding.

 

No termination or
repossession provided for in this Section shall relieve the Tenant of its liabilities and obligations under this Lease, all of
which shall survive any such termination or repossession. In the event of any such termination or repossession, the Tenant shall pay
to the Landlord either (i) in advance on the first day of each month, for what would have been the entire balance of the Term,
one-twelfth (1/12) (and a pro rata portion thereof for any fraction of a month) of the annual Basic Rent, Additional Rent and all
other amounts for which the Tenant is obligated hereunder, less, in each case, the actual net receipts by the Landlord by reason of
any reletting of the Premises after deducting the Landlord’s reasonable expenses in connection with such reletting, including,
without limitation, removal, storage and repair costs and reasonable brokers’ and reasonable attorneys’ fees, or (ii)
upon demand and at the option of the Landlord exercisable by the Landlord’s giving notice to the Tenant within six (6) months
after any such termination, the present value (computed at a capitalization rate based upon the so-called federal funds rate) of the
amount by which the payments of Basic Rent and Additional Rent reasonably estimated to be payable for the balance of the Term after
the date of the exercise of said option would exceed the payments reasonably estimated to be the fair rental value of the Premises
on the terms and conditions of this Lease over such period, determined as of such date. If the Lease is terminated pursuant to this
Section and Tenant vacates the Premises, Landlord shall, subject to the provisions of this sentence, use reasonable efforts to
relet the Premises following any such termination and vacation of the Premises and collect the sums due to Landlord as a result of
such reletting; provided, however, that any obligation imposed by law upon Landlord to relet the Premises shall be subject to the
right of Landlord and its affiliates to lease other available space prior to reletting the Premises and to lease the Building in a
harmonious manner with an appropriate mix of uses, tenants, floor areas and terms of tenancies, and the like.

 

    26 

     

    

 

Without thereby affecting any other right or remedy
of the Landlord hereunder, the Landlord may, at its option, cure for the Tenant’s account any default by the Tenant hereunder which
remains uncured after said thirty (30) days’ notice of default from the Landlord to the Tenant if Tenant failed to commence and
diligently pursue such cure within said thirty (30) days, and the reasonable cost to the Landlord of such cure together with an administrative
charge equal to fifteen (15%) percent of such cost shall be deemed to be Additional Rent and shall be paid to the Landlord by the Tenant
with the installment of Basic Rent next accruing. Tenant shall pay as Additional Rent Landlord’s reasonable expenses, including
reasonable attorneys’ fees, incurred in enforcing any obligations of Tenant under this Lease with which Tenant has failed to comply.

 

Nothing herein shall limit or prejudice the right
of Landlord to prove and obtain in a proceeding for bankruptcy, insolvency, arrangement or reorganization, by reason of the termination,
an amount equal to the maximum allowed by a statute or law in effect at the time when, and governing the proceedings in which, the damages
are to be proved, whether or not the amount is greater to, equal to, or less than the amount of the loss or damage which Landlord has
suffered.

 

	22.	Remedies Cumulative; Waivers

 

The specific remedies to which the Landlord may
resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to
which the Landlord may be lawfully entitled in any provision of this Lease or otherwise. The failure of the Landlord or the Tenant to
insist in any one or more cases upon the strict performance of any of the covenants of this Lease, or to exercise any option herein contained,
shall not be construed as a waiver or relinquishment for the future of such covenant or option. A receipt by the Landlord, or payment
by the Tenant, of Basic Rent or Additional Rent with knowledge of the breach of any covenant hereof shall not be deemed a waiver of such
breach, and no waiver, change, modification or discharge by the Landlord of any provision in this Lease shall be deemed to have been made
or shall be effective unless expressed in writing and signed by an authorized representative of the Landlord or the Tenant as appropriate.
Nor shall any endorsement or statement on any check or in any letter accompanying any check or payment be deemed an accord and satisfaction;
and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such installment or
pursue any other right or remedy. The delivery of keys (or any similar act) to Landlord shall not operate as a termination of the Term
or an acceptance or surrender of the Premises. The acceptance by Landlord of any rent following the giving of any default and/or termination
notice shall not be deemed a waiver of such notice.

 

    27 

     

    

 

	23.	Brokers

 

Landlord and Tenant each represent and warrant
to the other that it has had no dealings with any real estate brokers or finder in connection with this Lease other than the Broker. Landlord
shall indemnify, defend and hold harmless Tenant and its affiliates from any breach of such representation and warranty and Tenant shall
indemnify, defend and hold harmless Landlord and its affiliates from any breach of such representation and warranty.

 

	24.	Notices

 

All notices and other communications hereunder
shall, unless otherwise herein expressly provided, be in writing and shall be delivered by generally-recognized overnight courier service,
with a copy by certified mail, return receipt requested, and shall be deemed given when so delivered or twenty-four (24) hours after so
mailed, except that where any time period under this Lease is specified to commence from notice, such time period shall not be deemed

	25.	Estoppel Certificates

 

The Tenant hereby agrees
from time to time, after not less than ten (10) days’ prior written notice from Landlord or any Mortgagee, to execute,
acknowledge and deliver, without charge, to Landlord, the Mortgagee or any other person designated by Landlord, a statement in
writing certifying: that this Lease is unmodified and in full force and effect (or if there have been modifications, identifying the
same by the date thereof and specifying the nature thereof); that to the knowledge of Tenant there exist no defaults (or if there be
any defaults, specifying the same); the amount of the Basic Rent, the dates to which the Basic Rent, Additional Rent and other sums
and charges payable hereunder have been paid; that such party to its knowledge has no claims against the other party hereunder
except for the continuing obligations under this Lease (or if such party has any such claims, specifying the same) and other matters
that may reasonably be requested by the requesting party. Such statement shall be in the form attached as Exhibit E or
such other form as may reasonably be requested by the requesting party. Failure of Tenant to comply with this Section shall
constitute a default unless cured within a further ten (10) days’ following notice of such default.

 

    28 

     

    

 

 

		26.	Bind and Inure: Limited Liability of Landlord

 

All of the covenants, agreements, stipulations,
provisions, conditions and obligations herein expressed and set forth shall be considered as running with the land and shall extend to,
bind and inure to the benefit of the Landlord and the Tenant, which terms as used in this Lease shall include their respective successors
and assigns where the context hereof so admits.

 

The term “Landlord” as used in this
Lease shall refer only to the owner or owners from time to time of the Property or the Building, it being understood that no such owner
shall have any liability hereunder for matters arising from and after the date such owner ceases to have any interest in the Property
or the Building, Tenant agreeing that Landlord shall be liable only for breaches of its covenants occurring while it is owner of the Premises.
Tenant (and each person acting under Tenant) agrees to look solely to Landlord’s interest from time to time in the Property for
satisfaction of any claim against Landlord or any affiliate of Landlord. No trustee, beneficiary, partner, manager, member, agent or employee
of Landlord or of any affiliate of Landlord (or of any Mortgagee) shall ever be personally or individually liable; nor shall it or they
ever be answerable or liable in any equitable judicial proceeding or order beyond the extent of their interest in the Premises. Any lien
obtained to enforce any judgment against Landlord shall be subject and subordinate to any mortgage encumbering the Premises.

 

In no event shall the Landlord be liable to the
Tenant (or any person claiming under Tenant) for any special, consequential or indirect damages suffered by any person or entity by reason
of a default by the Landlord under any provisions of this Lease. It is expressly agreed by Landlord and Tenant that business interruption
costs and expenses are indirect and consequential damages under the terms of this Lease.

 

    29 

     

    

 

		27.	No Waste; Environmental Compliance

 

Tenant shall not itself, nor shall Tenant
permit or suffer persons acting under Tenant to, either with or without negligence, injure, overload, deface, damage or otherwise
harm the Property, the Premises or any part or component thereof; commit any nuisance; or permit any noise or odors to emanate
beyond the Premises; or permit any waste whatsoever to the Property or the Premises. Tenant represents, warrants and covenants to
Landlord that at all times during the Term Tenant (and persons acting under Tenant) will not generate, manufacture, store or
otherwise handle any Hazardous Materials or Wastes in the Building, the Premises or on the Property, except those as set forth on Exhibit F
hereto used in reasonable amounts in the conduct of Tenant’s business and in compliance with all applicable laws (which Exhibit F
may be updated from time to time as agreed upon by Landlord and Tenant). In addition to and not in limitation of the foregoing,
Tenant covenants to Landlord that: (a) Tenant (and persons acting under Tenant) shall (i) comply with all Laws applicable to the
discharge, generation, manufacturing, removal, transportation, treatment, storage, disposal and handling of Hazardous Materials or
Wastes as apply to the activities of the Tenant (and persons acting under Tenant), its (and their) directors, officers, employees,
agents, contractors, subcontractors, licensees, invitees, successors and assigns at the Premises, but only with respect to any
Hazardous Materials or Waste introduced to, generated at or released from the Property by Tenant (and persons acting under Tenant)
or any of the foregoing persons or entities; (ii) remove any Hazardous Materials or Wastes from the Premises which were introduced
to, generated at, or released from the Premises by Tenant (and persons acting under Tenant) or any of the foregoing persons or
entities in accordance with all applicable Laws and orders of governmental authorities having jurisdiction, (iii) pay or cause to be
paid all costs associated with such removal including restoration of the Premises, and (iv) indemnify Landlord from and against all
losses, claims and costs, in accordance with the final paragraph of this Section; (b) Tenant shall keep the Property free of any
lien imposed pursuant to any applicable Law in connection with the existence of Hazardous Materials or Wastes in or on the Premises,
but only with respect to any Hazardous Materials or Waste introduced to, generated at or released from the Property by Tenant (and
persons acting under Tenant) or any of the foregoing persons or entities; (c) Tenant (and persons acting under Tenant) shall not
install or permit to be installed in the Premises any asbestos, asbestos-containing materials, urea formaldehyde insulation or,
except as set forth on Exhibit F to allow to exist, any other chemical or substance which has been determined to be a
hazard to health and environment except in accordance with all applicable Laws and orders of governmental authorities having
jurisdiction; (d) Tenant (and persons acting under Tenant) shall not cause or permit to exist, as a result of an intentional or
unintentional act or omission on the part of Tenant or any occupant of the Premises, a releasing, spilling, leaking, pumping,
emitting, pouring, discharging, emptying or dumping of any Hazardous Materials or Wastes onto the Premises, but only with respect to
any Hazardous Materials or Waste introduced to, generated at or released from the Property by Tenant (and persons acting under
Tenant) or any of the foregoing persons or entities; (e) Tenant shall give all notifications and prepare all reports required by
Laws or any other law with respect to Hazardous Materials or Wastes existing on, released from or emitted from the Premises; (f)
promptly upon Tenant (and persons acting under Tenant) obtaining actual knowledge of the existence of the same, Tenant (and persons
acting under Tenant) shall promptly notify Landlord in writing of any release, spill, leak, emittance, pouring, discharging,
emptying or dumping of Hazardous Materials or Wastes in or on the Premises which is required to be reported to any governmental
authority pursuant to any applicable Law; and (g) Tenant (and persons acting under Tenant) shall promptly notify Landlord in writing
of any summons, citation, directive, notice, letter or other communication, written or oral, from any local, state or federal
governmental agency, or of any claim or threat of claim known to Tenant (and persons acting under Tenant), made by any third party
relating to the presence or releasing, spilling, leaking, pumping, emitting, pouring, discharging, emptying or dumping of any
Hazardous Materials or Wastes onto the Premises. The foregoing covenants shall not apply to Hazardous Materials or Wastes existing
in, at, under or emenating from the Premises, the Building or the Property at any time as a result of the act or negligence of
Landlord, or any of Landlord’s partners, employees, agents, contractors, subcontractors, licensees, invitees or any Uninvited
Third Party. For purposes of this Section, “Uninvited Third Party” shall mean any person who entered or enters upon the
Premises or Property without invitation or permission and releases Hazardous Materials or Wastes provided that such is not a result
respectively of the negligence of Landlord or Tenant (and persons acting under Tenant), or any of Landlord’s or Tenant’s
partners, employees, agents, contractors, subcontractors, licensees, invitees (or those of persons acting under Tenant).

 

    30 

     

    

 

The term “Hazardous Materials
or Wastes” shall mean any hazardous or toxic materials, pollutants, chemicals, or contaminants, including without limitation asbestos,
asbestos- containing materials, urea formaldehyde foam insulation, polychlorinated biphenyls (PCBs) and petroleum products as defined,
determined or identified as such in any laws, as hereinafter defined. Without limitation, Hazardous Materials or Wastes shall include
all substances described in the Clean Water Act, 33 U.S.C. § 1251 et seq. (1972), the Clean Air Act, 42 U.S.C. § 7401
et seq. (1970), the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, 42 U.S.C., and The
Resource Conservation and Recovery Act, 42 U.S.C. Subsection 6901 et seq.; in the Hazardous Materials Transportation Act;
in the Massachusetts Hazardous Waste Management Act, as amended, M.G.L. Chapter 21, and the Massachusetts Oil and Hazardous Material
Release Prevention Act, as amended, M.G.L. Chapter 21E and all other federal, state and local laws governing similar matters as they
may be amended from time to time as well as any judicial or administrative interpretation thereof, including any judicial or administrative
orders or judgments. Tenant shall execute affidavits, representations and the like from time to time at Landlord’s request concerning
Tenant’s best knowledge and belief regarding the presence or absence of Hazardous Materials or Wastes on the Premises or the Property.

 

Tenant hereby agrees to defend, indemnify and hold
harmless Landlord, its mortgagees, employees, agents, contractors, subcontractors, licensees, invitees, successors and assigns from and
against any and all claims, losses, damages, liabilities, judgments, costs and expenses (including, without limitation, attorneys’
fees and costs incurred in the investigation, defense and settlement of claims or remediation of contamination) incurred by such indemnified
parties as a result of the acts of Tenant or persons acting under Tenant with respect to the presence at or removal of Hazardous Materials
or Wastes from the Premises (except for Hazardous Materials or Wastes existing in or at the Premises, Building or Property prior to the
date of this Lease and not released by, through or under Tenant or existing in, on, under or emanating from the Premises, the Building
or the Property at any time as a result of the act or negligence of Landlord, or any of Landlord’s partners, employees, agents,
contractors, subcontractors, licensees, invitees, successors or assigns including as a result of the construction of the Building Improvements)
or as a result of or in connection with activities prohibited under this Section. Tenant shall bear, pay and discharge, as and when the
same become due and payable, any and all such judgments or claims for damages, penalties or otherwise against such indemnified parties,
shall hold such indemnified parties harmless against all claims, losses, damages, liabilities, costs and expenses, and shall assume the
burden and expense of defending all suits, administrative proceedings, and negotiations of any description with any and all persons, political
subdivisions or government agencies arising out of any of the occurrences set forth in this Section. Landlord shall give Tenant prompt
written notice of any such claim. Tenant may defend such claim with responsible counsel of its own choosing. Without limiting in any way
this indemnity and hold harmless agreement, Tenant shall have the right to settle claims for which Tenant is to indemnify and hold harmless
without first obtaining the consent of Landlord to such settlement on the condition that Landlord shall incur no cost, expense, liability
or damage on account of such settlement whatsoever to any party, and Tenant shall indemnify and hold harmless Landlord from all such costs,
expenses, liabilities and damages on account of such settlement.

 

    31 

     

    

 

To the knowledge of Landlord, (i) no Hazardous
Materials or Wastes requiring remediation or investigation under applicable environmental laws are present on the Property or the soil,
surface water or groundwater thereof and (ii) no action, proceeding or claim is pending or threatened regarding the Property concerning
any Hazardous Materials or Wastes or pursuant to any environmental law. Landlord shall, as and to the extent required by applicable law,
following notice by Tenant remove or remediate (or cause the responsible party to remove or remediate) any Hazardous Materials or Wastes
located in the Premises or Building that affect Tenant’s use of the Premises or portions of the Building as to which Tenant has
appurtenant rights under the Lease. The foregoing covenant shall not apply to any Hazardous Materials or Wastes that exist in the Premises
or the Building as a result of any act or omission of Tenant, its employees, agents, or guests, Tenant’s architect, Tenant’s
contractors, or any persons acting under or through Tenant. Landlord shall indemnify Tenant from any breach of the representation in the
first sentence of this paragraph and from any failure to remove or remediate as provided above and hereby agrees to defend, indemnify
and hold harmless Tenant, its directors, officers, employees, agents, contractors, subcontractors, licensees, invitees, successors and
assigns from and against any and all claims, losses, damages, liabilities, judgments, costs and expenses (including, without limitation,
reasonable third party attorneys’ fees and costs incurred in the investigation, defense and settlement of claims or remediation
of contamination) incurred by such indemnified parties as a result of the acts or the failure to act of Landlord or persons acting under
Landlord with respect to the presence at or removal of Hazardous Materials or Wastes from the Premises.

 

		28.	Applicable Law and Construction

 

This Lease may be executed in counterparts,
shall be construed as a sealed instrument, and shall be governed exclusively by the provisions hereof and by the laws of the state
where the Property is located without regard to principles of choice of law or conflicts of law. A facsimile signature to this Lease
shall be sufficient to prove the execution by a party. The covenants of Landlord and Tenant are independent, and such covenants
shall be construed as such in accordance with the laws of The Commonwealth of Massachusetts. If any provisions shall to any extent
be invalid, the remainder shall not be affected. Other than contemporaneous instruments executed and delivered of even date, if any,
this Lease contains all of the agreements between Landlord and Tenant relating in any way to the Premises and supersedes all prior
agreements and dealings between them. There are no oral agreements between Landlord and Tenant relating to this Lease or the
Premises. This Lease may be amended only by instrument in writing executed and delivered by both Landlord and Tenant. The provisions
of this Lease shall bind Landlord and Tenant and their respective successors and assigns, and shall inure to the benefit of Landlord
and its successors and assigns and of Tenant and its permitted successors and assigns. Where the phrases “persons acting
under” Landlord or Tenant or “persons claiming through” Landlord or Tenant or similar phrases are used, the
persons included shall be assignees, sublessees, licensees or other Transferees or successors of Landlord or Tenant as well as
invitees or independent contractors of Landlord or Tenant, and all of the respective employees, servants, contractors, agents and
invitees of Landlord, Tenant and any of the foregoing. As used herein, “non-monetary default” shall mean a default that
cannot be substantially cured by the payment of money. The titles are for convenience only and shall not be considered a part of the
Lease. This Lease shall not be construed more strictly against one party than against the other merely by virtue of the fact that it
may have been prepared primarily by counsel for one of the parties, it being recognized that both Landlord and Tenant have
contributed substantially and materially to the preparation of this Lease. If Tenant is granted any extension or other option, to be
effective the exercise (and notice thereof) shall be unconditional; and if Tenant purports to condition the exercise of any option
or to vary its terms in any manner, then the option granted shall be void and the purported exercise shall be ineffective. The
enumeration of specific examples of a general provisions shall not be construed as a limitation of the general provision. Unless a
party’s approval or consent is required by the express terms of this Lease not to be unreasonably withheld, such approval or
consent may be withheld in the party’s sole discretion. The submission of a form of this Lease or any summary of its terms
shall not constitute an offer by Landlord to Tenant; but a leasehold shall only be created and the parties bound when this Lease is
executed and delivered by both Landlord and Tenant and approved by the holder of any mortgagee of the Premises having the right to
approve this Lease. Nothing herein shall be construed as creating the relationship between Landlord and Tenant of principal and
agent, or of partners or joint venturers or any relationship other than landlord and tenant. This Lease and all consents, notices,
approvals and all other related documents may be reproduced by any party by any electronic means or by facsimile, photographic,
microfilm, microfiche or other reproduction process and the originals may be destroyed; and each party agrees that any reproductions
shall be as admissible in evidence in any judicial or administrative proceeding as the original itself (whether or not the original
is in existence and whether or not reproduction was made in the regular course of business), and that any further reproduction of
such reproduction shall likewise be admissible. If any payment in the nature of interest provided for in this Lease shall exceed the
maximum interest permitted under controlling law, as established by final judgment of a court, then such interest shall instead be
at the maximum permitted interest rate as established by such judgment. Landlord and Tenant expressly agree that there are and shall
be no implied warranties of merchantability, habitability, suitability, fitness for a particular purpose or of any other kind
arising out of this Lease, and there are no warranties that extend beyond those expressly set forth in this Lease.

 

    32 

     

    

 

		29.	Memorandum of Lease.

 

This Lease shall not be recorded in the land records.
Within fifteen (15) days after the written request of either party, Landlord and Tenant agree to execute and acknowledge and Tenant may
record in the land records a memorandum of the basic terms of this Lease, including, the Term, rights to extend the Term, rights and obligations
of the parties with respect to assignment and sublease of Tenant’s interest in the Lease and right of first refusal. At the expiration
or earlier termination of the Term, Landlord and Tenant shall execute and acknowledge for recording a termination of any recorded memorandum
of lease, Tenant hereby constituting Landlord and its successors and assigns as its attorney in fact with full power of substitution to
so execute and acknowledge such termination if Tenant fails so to do within ten (10) days. This provision shall expressly survive expiration
or the earlier termination of the Lease.

 

		30.	Intentionally omitted.

 

		31.	Payments; Force Majeure

 

Except as set otherwise set forth in this Lease
with respect to payments due earlier, any payment due hereunder shall be due within thirty (30) days following demand therefor. If a party
cannot perform its obligations due to causes or events beyond its reasonable control (other than the inability to make payments when due,
including paying rent), the time provided for performing such obligations shall be extended by a period of time equal to the duration
of such causes or events. Causes or events beyond a party’s reasonable control include acts of God, war, civil commotion, labor
disputes, strikes, public disturbances, fire, flood or other casualty, shortages of or the inability to obtain labor or material from
customary sources on customary terms, government regulation or restriction, weather conditions and acts, neglects or delays of the other
party. The foregoing two sentences comprise the definition of “Force Majeure.”

 

    33 

     

    

 

		32.	Signs

 

No sign, name, placard, advertisement or notice
visible from the exterior of the Premises shall be inscribed, painted or affixed by Tenant on any part of the Building without the prior
written approval of Landlord. All signs or letterings on doors, or otherwise, approved by Landlord, shall be inscribed, painted or affixed
by a person reasonably approved by Landlord and at the sole cost and expense of Tenant. Notwithstanding the foregoing, Landlord will provide,
at Landlord’s expense, (x) a sign on the shared monument sign in front of the Building (the size of such space to be reasonably
appropriate based on Tenant’s Pro Rata Share) so long as no Transfer (other than a Permitted Transfer) or default by Tenant occurs,
(y) entry signage to the Premises in Building standard size, location and design and (z) signage in the west lobby of the Building in
Building standard size, location and design.

 

Notwithstanding the foregoing, Tenant shall upon
compliance with all applicable laws, including town bylaws and so long as no Transfer (other than a Permitted Transfer) or default by
Tenant occurs, have the right to install a sign on the side of the Building in a location designated by Landlord on the exterior façade
of the Building at the main entrance of the west side of the Building at Tenant’s expense, subject to Landlord’s prior reasonable
approval of the design of such sign and subject to compliance with all applicable legal requirements. Tenant shall keep such sign in good
condition and repair at Tenant’s expense. At the expiration or earlier termination of this Lease, Tenant shall, at its sole cost
and expense, remove such sign and repair and restore the area where such sign is installed to Landlord’s reasonable satisfaction
and leave such area in good order and repair, reasonable wear and tear excepted.

 

		33.	Intentionally omitted

 

		34.	Financial Statements

 

Tenant shall furnish to Landlord within one
hundred twenty (120) days after each of Tenant’s fiscal years during the Term an accurate, up-to-date, audited if available,
financial statement of Tenant showing Tenant’s financial condition for the preceding fiscal year. If not so furnished, Tenant
shall furnish the same to Landlord within fifteen (15) days of Landlord’s request therefor. If no audited financial statement
is prepared, such statement will be certified by the CFO or Treasurer of Tenant. Unless public by other means, Landlord will
maintain confidential such statement, except as required by an applicable law or court order; however Landlord may provide such
statements to Landlord’s prospective and actual lenders and purchasers, and its and their accountants, attorneys and partners,
as long as Landlord advises the recipients of the existence of Landlord’s confidentiality obligation. So long as Tenant is a
publicly-traded company that makes public reports as required by the Securities and Exchange Commission, those publicly-available
reports shall satisfy all obligations of Tenant under this Section.

 

    34 

     

    

 

		35.	Waiver of Jury Trial; Other

 

LANDLORD AND TENANT AGREE THAT TO EXTENT PERMITTED
BY LAW, EACH SHALL AND HEREBY DOES WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER AGAINST THE OTHER ON
ANY MATTER WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, TENANT’S
USE OR OCCUPANCY OF THE PREMISES AND/OR EMERGENCY OR STATUTORY REMEDY. Nothing in this Lease shall limit the right of Landlord to prove
and obtain in proceedings for bankruptcy or insolvency an amount equal to the maximum allowed by any statute or rule of law in effect
at the time; and Tenant agrees that the fair value for occupancy of all or any part of the Premises at all times shall never be less than
the Basic Rent and all Additional Rent payable from time to time. Tenant shall also indemnify and hold Landlord harmless in the manner
provided in Section 14 if Landlord shall become or be made a party to any claim or action (a) instituted by Tenant against any third
party, or by any third party against Tenant, or by or against any person claiming through or under Tenant; (b) for foreclosure of any
lien for labor or material furnished to or for Tenant or such other person; (c) otherwise arising out of or resulting from any act or
transaction of Tenant or such other person; or (d) necessary to protect Landlord’s interest under this Lease in a bankruptcy proceeding,
or other proceeding under Title 11 of the United States Code, as amended. Landlord and Tenant further agree that any action arising out
of this Lease (except an action for possession by Landlord, which may be brought in whatever manner or place provided by law) shall be
brought in the Trial Court of the Commonwealth of Massachusetts, Superior Court Department, in the county where the Premises are located.

 

		36.	Security Deposit

 

Tenant shall provide to Landlord a clean, irrevocable
letter of credit as security for the performance of the obligations of Tenant under this Lease, subject to the terms and conditions set
forth in this Section (together with any renewal or replacement thereof in accordance herewith, the “Letter of Credit”).
Tenant shall provide the Letter of Credit to Landlord upon Tenant’s execution of this Lease, in the amount of Two Hundred Fifty
Thousand Dollars ($250,000) (“Original Amount”). Any Letter of Credit delivered hereunder shall comply with the requirements
of this Section.

 

    35 

     

    

 

If Landlord has not previously drawn on the
Letter of Credit, Tenant is not then in default under the Lease, and no event or condition then exists which with notice and the
passage of time would give rise to such a default, then Tenant may decrease the amount of the Letter of Credit required to be
maintained hereunder to the amounts on the dates set forth in the following schedule, and upon Tenant’s request Landlord shall
provide such confirmation or acknowledgement as Tenant may reasonably request to effect such reduction of the Letter of Credit:

 

	Original Amount:	 	$	250,000	 
	First Day of Lease Year 3: 	 	$	150,000	 
	First Day of Lease Year 5:	 	$	100,000	 

 

The Letter of Credit (i) shall be irrevocable and
shall be issued by Silicon Valley Bank or another commercial bank reasonably acceptable to Landlord that has an office in Boston, Massachusetts
or New York City that accepts requests for draws on the Letter of Credit, (ii) shall require only the presentation to the issuer of a
notice from the holder of the Letter of Credit stating that Landlord is entitled to draw on the Letter of Credit pursuant to the terms
of the Lease, (iii) shall be payable to Landlord or its successors in interest as the Landlord and shall be freely transferable without
cost to any such successor or any lender holding a collateral assignment of Landlord’s interest in the Lease, (iv) shall be for
an initial term of not less than one year and contain a provision that such term shall be automatically renewed for successive one-year
periods unless the issuer shall, at least forty five (45) days prior to the scheduled expiration date, give Landlord notice of such nonrenewal,
and (v) shall otherwise be in form and substance reasonably acceptable to Landlord. Notwithstanding the foregoing, the term of the Letter
of Credit for the final period shall be for a term ending not earlier than the date thirty (30) days after the last day of the Term. In
the event that the issuer ceases to be reasonably acceptable to Landlord, due to a deterioration in its financial condition or change
in status that threatens to compromise Landlord’s ability to draw on the Letter of Credit as determined in good faith by Landlord,
then Tenant shall provide a replacement Letter of Credit from an issuer satisfying the terms of this Exhibit within thirty (30) days
after Landlord’s notice of such event.

 

Landlord shall be entitled to draw upon the Letter
of Credit for its full amount or any portion thereof if (a) Tenant shall fail to perform any of its obligations under the Lease after
the expiration of any applicable notice and cure period, or fail to perform any of its obligations under the Lease and transmittal of
a default notice is barred by applicable law, or fail to perform any of its obligations under the Lease and any applicable notice and
cure period would expire prior to the expiration of the Letter of Credit, or (b) not less than thirty (30) days before the scheduled expiration
of the Letter of Credit, Tenant has not delivered to Landlord a new Letter of Credit in accordance with this Section. Without limiting
the generality of the foregoing, Landlord may, but shall not be obligated to, draw on the Letter of Credit from time to time in the event
of a bankruptcy filing by or against Tenant and/or to compensate Landlord, in such order as Landlord may determine, for all or any part
of any unpaid rent, any damages arising from any termination of the Lease in accordance with the terms of the Lease, and/or any damages
arising from any rejection of the Lease in a bankruptcy proceeding commenced by or against Tenant. Landlord may, but shall not be obligated
to, apply the amount so drawn to the extent necessary to cure Tenant’s failure.

 

Any amount of the Letter of Credit drawn in
excess of the amount applied by Landlord to cure any such failure shall be held by Landlord as a cash security deposit for the
performance by Tenant of its obligations under the Lease. Any cash security deposit may be mingled with other funds of Landlord and
no fiduciary relationship shall be created with respect to such deposit, nor shall Landlord be liable to pay Tenant interest
thereon. If Tenant shall fail to perform any of its obligations under this Lease, Landlord may, but shall not be obliged to, apply
the cash security deposit to the extent necessary to cure Tenant’s failure. After any such application by Landlord of the
Letter of Credit or cash security deposit, as the case may be, Tenant shall reinstate the Letter of Credit to the amount originally
required to be maintained under the Lease, upon demand. Provided that Tenant is not then in default under the Lease, and no
condition exists or event has occurred which after the expiration of any applicable notice or cure period would constitute such a
default, within thirty (30) days after the expiration or sooner termination of the Term the Letter of Credit and any cash security
deposit, to the extent not applied, shall be returned to the Tenant, without interest.

 

    36 

     

    

 

In the event of a sale of the Building or lease,
conveyance or transfer of the Building, Landlord shall transfer the Letter of Credit or cash security deposit to the transferee. Upon
such transfer, the transferring Landlord shall be released by Tenant from all liability for the return of such security, and Tenant agrees
to look to the transferee solely for the return of said security. The provisions hereof shall apply to every transfer or assignment made
of the security to such a transferee. Tenant further covenants that it will not assign or encumber or attempt to assign or encumber the
Letter of Credit or the monies deposited herein as security, and that neither Landlord nor its successors or assigns shall be bound by
any assignment, encumbrance, attempted assignment or attempted encumbrance.

 

		37.	Decommissioning

 

Prior to the expiration of this Lease (or within
thirty (30) days after any earlier termination), Tenant shall clean and otherwise decommission all interior surfaces (including floors,
walls, ceilings, and counters), piping, supply lines, waste lines and plumbing in and/or exclusively serving the Premises, and all exhaust
or other ductwork in and/or exclusively serving the Premises, in each case which has carried or released or been exposed to any Hazardous
Materials or Wastes so as to permit the report hereinafter called for by this Section to be issued.

 

Without limiting the generality of the foregoing,
the areas subject to such cleaning, decommissioning and reporting shall include chemical storage areas and containers and pipes and ducts
exposed to Hazardous Materials or Wastes. Prior to the expiration of this Lease (or within thirty (30) days after any earlier termination),
Tenant, at Tenant’s expense, shall obtain for Landlord a report addressed to Landlord and its Mortgagee (and, at Tenant’s
election, Tenant) by a reputable licensed site professional (LSP) that is designated by Tenant and acceptable to Landlord in Landlord’s
reasonable discretion, which report shall be based on the environmental engineer’s inspection of the Premises and shall show:

 

(i)                 that
the Hazardous Materials or Wastes, to the extent, if any, existing prior to such decommissioning, have been removed as necessary so
that the interior surfaces of the Premises (including floors, walls, ceilings, and counters), piping, supply lines, waste lines and
plumbing, and all such exhaust or other ductwork in and/or exclusively serving the Premises, may be reused by a subsequent tenant or
disposed of in compliance with applicable Environmental Laws without taking any special precautions for Hazardous Materials or
Wastes, without incurring special costs or undertaking special procedures for demolition, disposal, investigation, assessment,
cleaning or removal of Hazardous Materials or Wastes and without incurring regulatory compliance requirements or giving notice in
connection with Hazardous Materials or Wastes; and

 

    37 

     

    

 

(ii)             
that the Premises may be reoccupied for the Permitted Uses described in Section 5, or demolished or renovated without taking
any special precautions for Hazardous Materials or Wastes, without incurring special costs or undertaking special procedures for disposal,
investigation, assessment, cleaning or removal of Hazardous Materials or Wastes and without incurring regulatory requirements or giving
notice in connection with Hazardous Materials or Wastes.

 

For purposes of clause (ii) above: “special
costs” or “special procedures” shall mean costs or procedures, as the case may be, that would not be incurred but for
the nature of the Hazardous Materials or Wastes as Hazardous Materials or Wastes instead of non-hazardous materials. The report shall
include reasonable detail concerning the clean-up location, the tests run and the analytic results.

 

If Tenant fails to perform its obligations under
this Section, without limiting any other right or remedy, Landlord may, on five (5) business days’ prior written notice to Tenant
perform such obligations at Tenant’s expense, and Tenant shall promptly reimburse Landlord as additional rent upon demand for all
costs and expenses reasonably incurred together with an administrative charge equal to ten percent (10%) of such costs and expenses.

 

To the extent that Tenant surrenders any portion
of the Premises to Landlord, Tenant’s obligations under this Section shall apply with respect to such surrendered portion of
the Premises at the time of such surrender, and such surrender shall not be deemed to have occurred until Tenant’s obligations under
this Section shall have been satisfied.

 

Tenant’s obligations under this Section shall
survive the expiration or earlier termination of this Lease.

 

		38.	Rooftop Equipment.

 

Subject to the following provisions of this Section,
Tenant shall have the right to install, operate and maintain, on the roof of the Building (the “Roof Premises”) at Tenant’s
expense and risk, a lawfully permitted satellite dish and associated equipment, a back-up generator and cables, a compressed air system
and a chiller with chiller lines (collectively, the “Rooftop Equipment”), subject to Landlord’s approval of the size,
weight and location of same.

 

(a)              
If the weight of any of the Rooftop Equipment exceeds the live load bearing capacity of the roof, Tenant’s plans and specifications
for the installation thereof shall include details of structural engineering and structural reinforcement so as to ensure the structural
integrity of the roof upon installation of the Rooftop Equipment.

 

(b)              
Tenant shall submit to Landlord for its approval, a full set of engineering plans and specifications for the proposed Rooftop Equipment
installation.

  

    38 

     

    

 

(c)              
 Tenant shall make all required conduit and/or cable connections between Tenant’s equipment in the Premises and the Rooftop
Equipment subject to approval of such connections by Landlord.

 

(d)              
Tenant shall obtain all necessary municipal, state and federal permits and authorizations required to install, maintain and operate
the Rooftop Equipment and pay any changes levied by any governmental agencies which are the result of the Rooftop Equipment and/or the
installation and/or use thereof.

 

(e)              
Tenant shall maintain the Roof Premises and the Rooftop Equipment in a good state of repair.

 

(f)               
Tenant shall use (at Tenant’s cost) Landlord’s roof contractor to perform and repair any penetrations necessary to
the roof in connection with the installation and removal of the Rooftop Equipment. In no event will Tenant be authorized to make any penetrations
that would void Landlord’s roof warranty.

 

(g)              
At the expiration or earlier termination of this Lease, Tenant shall remove the Rooftop Equipment and surrender and restore the
Roof Premises to Landlord in substantially as good condition as when entered.

 

(h)              
The liability insurance to be carried by Tenant shall include coverage for any activity on the Roof Premises. Tenant shall pay
any increase in rates for Landlord’s insurance resulting from the installation and use of the Roof Premises and/or the Rooftop Equipment
by Tenant.

 

(i)                
The Rooftop Equipment shall be utilized solely on behalf of Tenant. Tenant shall not license, lease or otherwise permit the use
of the same by any other party.

anniversary of the execution date hereof, Tenant shall have the on-going right to request the 2018 TI Allowance, or a portion
thereof, by written notice to Landlord to be accompanied by all invoices, lien waivers and/or municipal certificates, when
applicable, to substantiate the work completed. Provided Tenant meets the conditions herein, Landlord shall reimburse Tenant for the
amount requested, not to exceed the full amount of the 2018 TI Allowance, within thirty (30) days of Landlord’s receipt of
written notice and documentation as aforesaid. Any unused portions of the 2018 TI Allowance not requested beyond the second
(2nd) anniversary of the execution date hereof shall be forfeited.

		8.	External Storage. During the Term of the Lease, Tenant shall have permission to have access to and use a portion of the exterior
portion of the Property and enjoy 24-hour access thereto to use, maintain and replace materials and equipment, as hereinafter defined,
at a location to be mutually agreed upon by Landlord and Tenant (the, “External Storage Area”). The External Storage Area
is to be used by Tenant solely for the installation, operation, maintenance, repair and replacement during the Term of this Lease of a
liquid nitrogen tank, oxygen tank, and generator (collectively, the “Exterior Equipment”). The Exterior Equipment shall also
include one conduit as necessary to connect any such equipment to the Premises subject to Landlord’s prior written approval not
to be unreasonably withheld, conditioned or delayed, to be located in a vertical chase mutually designated by Landlord and Tenant. Tenant’s
installation and operation of the Exterior Equipment and its obligations with respect thereto shall be all in accordance with the terms,
provisions, conditions and agreements contained in this Lease (including, without limitation, provisions regarding compliance with applicable
law set forth in Lease Section 3 and Lease Section 11 thereof), shall be without interference with the business
and telecommunications of other tenants or any other person, and Tenant shall be responsible for installing, maintaining and implementing
all related safety measures and devices reasonably required in connection with the installation, operation or use of the Exterior Equipment,
and (subject to applicable waivers of claims and rights of subrogation set forth in the Lease, and except for matters arising from the
negligence or willful misconduct of Landlord or its agents, employees or contractors) shall be solely responsible for all damage to persons
or property resulting from the installation, operation or use of the Exterior Equipment in each case indemnifying and holding harmless
Landlord in the manner elsewhere provided in this Lease. Without limiting the generality of the foregoing, (x) Tenant’s installation,
operation and use of the Exterior Equipment shall not interfere with the Building Systems or with other tenants in the Building and (y) Tenant
shall be solely responsible, at Tenant’s cost, for the repair, maintenance and, if applicable, landscaping of the External Storage
Area and for the payment of any personal property taxes attributable to the Exterior Equipment.

 

Tenant shall install the Exterior Equipment in the External
Storage Area at its sole cost and expense, at such times and in such manner as Landlord may reasonably designate and in accordance with
all of the applicable provisions of this Lease. Landlord shall not be obligated to perform any work or incur any expense to prepare the
External Storage Area for Tenant’s use thereof.

 

Prior to commencing installation of the Exterior Equipment,
Tenant shall provide Landlord with (i) copies of all required permits, licenses and authorizations which Tenant will obtain at its own
expense and which Tenant will maintain at all times during the operation of the Exterior Equipment; and (ii) a certificate of insurance
evidencing insurance coverage as required by this Lease and any other insurance reasonably required by Landlord for the installation and
operation of the Exterior Equipment.

 

Tenant shall pay to Landlord as Additional Rent all applicable
taxes or governmental charges, fees, or impositions upon Landlord and arising solely out of Tenant’s use of the External Storage
Area, and the amount, if any, by which Landlord’s insurance premiums increase as a result of the installation of the Exterior Equipment.

 

    3

     

    

 

At the expiration or earlier termination of the Lease or
the permanent termination of the operation of any portion of the Exterior Equipment by Tenant, Tenant shall, at its sole cost and expense,
(i) remove the Exterior Equipment (or the applicable portion thereof) from the External Storage Area and the Building in accordance with
the terms of Lease Section 3, (ii) repair and restore such External Storage Area, including (if applicable) the roof and roof
membrane, to Landlord’s reasonable satisfaction and leave the External Storage Area in good order and repair, reasonable wear and
tear excepted and (iii) pay all amounts due and owing with respect to this Section up to the date of the termination thereof. If
Tenant does not remove the Exterior Equipment when so required, the Exterior Equipment shall become Landlord’s property and, at
Landlord’s election, Landlord may remove and dispose of the Exterior Equipment and charge Tenant for all costs and expenses incurred
as Additional Rent. Notwithstanding that Tenant’s use of the External Storage Area shall be subject at all times to and shall be
in accordance with the terms, covenants, conditions and agreements contained in this Lease, the External Storage Area shall not be deemed
part of the Premises. All Tenant obligations under this Section shall survive the expiration or earlier termination of the Term of
this Lease.

 

Landlord may not unreasonably withhold, delay or condition
any consent of Landlord applicable under this Section unless the matter that is the subject of such consent would, in Landlord’s
reasonable determination, (i) adversely affect building systems, including but not limited to fire-safety, telecommunications, curtain
wall, electrical, heating, ventilation, plumbing or other mechanical systems, (ii) adversely affect any structural elements of the Building,
the curtain wall or any exterior signage, (iii) adversely affect any other tenant of the Building, or (iv) void or impair any warranty
applicable to the roof of the Building.

 

		9.	Back-Up Generator. During the Term, Landlord grants to Tenant permission, without additional charge (except that Tenant will
be responsible for the costs of actual connection), to connect to the Building’s back-up generator in order to provide a source
of emergency power for Tenant’s cold storage unit (“Tenant’s Equipment”). Tenant’s Equipment shall draw
a maximum of 100 amps of service. Tenant shall be responsible for the connection between Tenant’s Equipment and the back-up
generator and shall not make any such connection without the prior review and approval of Landlord. Landlord shall be responsible for
general maintenance of the back-up generator. Subject to the provisions of Section 13 of the Lease, Tenant will indemnify and hold
Landlord harmless from any loss, cost, damage or expense suffered by Landlord as a result of Tenant’s use of the Building’s
back-up generator.

 

		10.	Pod L2/A7. As of the Sixth Amendment Date, Landlord’s right to recapture Pod L2/A7 Storage per paragraph 6 of the Fourth
Amendment is hereby null and void. In addition, should adjacent space in L2/A7, as identified by the hatched area on Exhibit B attached
hereto, become available for lease during the Term, Landlord shall provide written notice thereof to Tenant (“Notice of Availability”).
Said adjacent space shall be “available for lease” when such space will become available because the current tenant’s
lease has or will expire without a renewal or extension thereof. Landlord shall only be required to provide said Notice of Availability
and is not required to reserve said space for Tenant in any way.

 

    4

     

    

 

		11.	Cafeteria. Landlord currently provides food service to the tenants and occupants of the Building
                                                                                                   from 6:30 am to 2:00 pm Monday through Friday. Landlord has agreed to expand the Building’s food service to accommodate
                                                                                                   employees working outside of the existing food service hours. This may be accomplished by
extending the cafeteria’s operating hours or by the implementation of a grab-n-go solution. Landlord shall use commercially reasonable
efforts to implement a mutually agreeable food service solution on or before December 31, 2018.

 

		12.	Termination Option. Tenant shall have a one-time right to terminate the Lease (the “Termination Option”) on July 31,2024
(the “Termination Date”), by giving written notice thereof to Landlord no later than July 31, 2023, provided that at
the time of giving such notice there exists no default by Tenant (continuing uncured beyond the expiration of all applicable notice and
grace periods). As a further condition to any such early termination, on or before the Termination Date, Tenant shall make a payment to
Landlord along with delivery of said termination notice, of a “termination fee” in the amount of the sum of all unamortized
transaction costs (including the 2018 TI Allowance, brokerage commissions and legal fees) paid by Landlord in connection with this Sixth
Amendment calculated on a level payments basis with interest at 6% per annum plus two months’ Basic Rent at the rate in place at
the time of the Termination Date.

 

		13.	Consent of Lender. As a condition to this Sixth Amendment, Landlord will, within ten (10) business days after the date hereof
and at Landlord’s cost, obtain and deliver to Tenant the consent of Landlord’s mortgage lender to this Sixth Amendment.

 

		14.	Brokerage. Tenant and Landlord each warrants and represents that it has dealt with no broker other than Cushman & Wakefield
and Farley White Management Company (collectively, the “Brokers”) in connection with this transaction and each agrees to defend,
indemnify and save the other harmless from and against any and all claims for a commission arising out of this Sixth Amendment made by
anyone other than the Brokers (as defined herein) claiming to have had dealings with the indemnifying party. The brokerage commission
of the Brokers will be paid by Landlord in accordance with the terms of a separate agreement.

 

		15.	Counterparts. This Amendment may be executed in multiple counterparts, each of which shall constitute an original. Any executed
copy of this Amendment delivered by confirmed facsimile or electronic mail shall be deemed to be binding to the same extent as an original
executed copy of this Amendment. If so executed and delivered by one or both of the parties via facsimile or electronic mail, each party
agrees to deliver to the other party, a complete original, manually signed copy of this Amendment upon request.

 

		16.	No Default; Approvals. Landlord hereby represents that Tenant is not in default to the best of Landlord’s knowledge of
its obligations or covenants under the Lease as of the date hereof. By executing and delivering this Amendment, each of the parties represents
and warrants to the other that such party has obtained any and all third party consents and/or approvals necessary for such party to enter
into this Sixth Amendment.

 

		17.	Ratification. In all respects, the Lease as hereby amended and modified, is hereby ratified, confirmed and approved.

 

Except as specifically amended by the terms of this Sixth
Amendment, all of the terms, conditions and provisions of the Lease shall remain in full force and effect throughout the Term of the Lease.
From and after the date hereof, the Lease and this Sixth Amendment shall collectively be referred to as the “Lease.”
