For good and valuable consideration,

		1.	License.

 

		(a)	License Description. Licensor grants to Licensee the following (A) and (B), of which shall

and laboratory space consistent with current zoning for the Building and all applicable laws; (ii) conduct Licensee’s business;
and (iii) collaborate with Licensor’s staff and other licensees in accordance with this Agreement: (A) a non- transferable,

portion of the floor plan attached to this Agreement as Exhibit 1 (“Lab Suites”), and (ii) First Floor
Offices, more specifically identified in the blue-shaded portion of the floor plan attached to this Agreement as Exhibit 1
(“Office Suites”) (Lab Suites and Office Suites are collectively the “Licensed Premises”) and (B) a
non-transferable, non-exclusive, non-assignable license to use any common areas (“Shared Premises”), subject to Licensor’s
reasonable rules and restrictions; provided, however, in the event of a conflict between any such rules and regulations and
this Agreement, this Agreement shall control. The parties acknowledge in all events during the Term (as hereinafter defined) of this Agreement,
the Shared Premises shall include access to those conference room spaces, kitchen, snack, , showers, and wellness room that exist as of
the date of this Agreement, subject to Licensor and Landlord’s reasonable rules and regulations. Subject to the deliver requirements
set forth in Section 2(a) below, Licensee shall accept the Licensed Premises and Shared Premises in their “as-is”
conditions and Licensor shall have no obligation to alter, repair or otherwise prepare the Licensed Premises for Licensee’s use
or to pay for, or provide any, improvements to the Licensed Premises except as expressly provided herein. Licensee shall not use the Licensed
Premises or Shared Premises for any use other than the foregoing, including but not limited to medical care or human clinical trials,
without first obtaining written permission from Licensor, which Licensor may withhold in its sole discretion.

 

    	 	1	 

     

    

 

		(b)	Scope of License. The License shall not include access to any additional office or laboratory space
in the Building except the Licensor has agreed to work with the Landlord to procure a conference room on the first floor of the Building
for Licensee’s exclusive use. To the extent said conference room is acquired, the parties agree an amendment to this License will
be executed to set forth the relevant terms, which may include Licensee paying additional License Fees or sums hereunder. Licensee understands
and agrees that other licensee(s) may jointly occupy portions of the Building, not including the Licensed Premises, which shall be
exclusive to Licensee, but including but not limited to the Shared Premises. Licensee agrees to cooperate and coordinate with any other
licensee(s) that occupies portions of the Building and that, other than the Licensed Premises, use of any other portion of the Building
shall not be exclusive to Licensee. Except as set forth herein, Licensor shall have no liability for the actions of any other licensee(s),
persons or entities using or occupying the Building.

 

		(c)	Occupants. The License shall only grant Licensee, and no more than one hundred (100)
of Licensee’s members, employees or agents (collectively, “Occupants”), access to the Licensed Premises and Shared
Premises; provided, however, that Licensor may grant access to additional Occupants (“Additional Occupants”) as set
forth in Section 3 below.

 

		2.	Term and Termination.

 

		(a)	Term. Unless terminated earlier in accordance with this Section 2, the term (“Term”)
of this Agreement shall commence on November 1, 2020 (“Term Commencement Date”) and expire on November 30,
2025 (“Expiration Date”); provided, however, notwithstanding the foregoing, Licensor shall deliver the Licensed Premises
with certain construction and finishes as set forth in Exhibit 1(a). Under no circumstance shall Licensor be liable to Licensee
for failure to provide access to the Licensed Premises or Shared Premises on or before November 1, 2020; provided, however, that
if Licensor is unable to provide Licensee access to the Licensed Premises on or before November 1, 2020 with the Licensor’s
Work Substantially Complete (as such terms are defined in Exhibit 1(a)), the Term Commencement Date shall be extended by the
number of days Licensor is unable to provide access to the Licensed Premises. Notwithstanding the foregoing to the contrary, in the event
the Licensed Premises has not been delivered to Licensee on or before November 15, 2020 with the Licensor’s Work Substantially
Complete (the “Delivery Condition”), subject to Licensee Delay (as such term is defined in Exhibit 1(a)),
Licensee shall be entitled to (i) one (1) additional day of abatement of the Licensee Fee for each day from November 15,
2020 through December 15, 2020 that the Licensed Premises has not been delivered in the Delivery Condition, and (ii) two (2) additional
days of abatement of the License Fee for each day from December 16, 2020 on until the Licensed Premises has been delivered to Licensee
in the Delivery Condition. Upon either party’s request, Licensor and Licensee shall execute a mutually-agreeable Term Commencement
Agreement that sets forth the Term Commencement Date, Expiration Date and Term.

 

    	 	2	 

     

    

 

After November 30, 2023, Licensee
shall have the right to terminate this Agreement provided Licensee gives Licensor written notice of its exercise of its termination right
no less than nine (9) months prior to requested termination date. By way of clarification, Licensee shall be entitled to provide
notice beginning March 1, 2023 for a termination right effective on or after November 31, 2023. There shall be no termination
fee or penalty associated with Licensee’s exercise of its termination right in accordance with this paragraph.

 

Provided Licensee is not in breach of
the Agreement, Licensee shall have the option to extend the Term for one additional three (3) year period (“Extended Term”)
upon the terms set forth herein at the prevailing market license rate for the SmartLabs Program in submarket area, Boston Seaport, with
the Extended Term commencing immediately upon the Expiration Date. Licensee shall exercise the foregoing option by written notice to Licensor
given no less than twelve (12) months prior to the Expiration Date. The foregoing option shall terminate if notice is not timely given,
time being of the essence.

 

		(b)	Termination. Licensor may terminate this Agreement immediately for “Default” by giving
written notice to Licensee specifying the cause. “Default” shall be deemed as: (i) Licensee’s failure to
pay when due any sum of money under this Agreement, and such failure shall continue for a period of five (5) days after written notice
from Licensor to Licensee that such payment was not paid when due; (ii) failure to comply with any covenants contained herein or
(iii) use of the Licensed Premises or Shared Premises in violation of any rules and procedures promulgated by Licensor or Landlord
and to the extent Licensee shall not cure such failure within thirty (30) days after written notice of such failure from Licensor to Licensee;
provided, however, that such failure shall not be deemed a Default if such failure could not reasonably be cured during such thirty (30)
day period, Licensee has commenced the cure within such thirty (30) day period and thereafter is diligently pursuing such cure to completion,
but the total aggregate cure period shall not exceed forty five (45) days; further provided, however, in the event any Default endangers
the health and/or safety of any other Building occupant and/or the Building itself, such failure shall be deemed a Default if Licensee
receives notice of the same (which may be oral) and fails to cure within 24 hours, whereas for the avoidance of doubt in such instances
Licensor shall have the immediate right to terminate this License following such failure to cure within 24 hours. Upon the occurrence
of any of the foregoing, and at any time thereafter, with or without further notice or demand and without limiting Licensor in the exercise
of any right or remedy that Licensor may have, Licensor may do any or all of the following by written notice to Licensee or by any lawful
means, (A) terminate Licensee’s access to the Licensed Premises, or (B) terminate the License. In either instance, Licensee
shall immediately surrender the Licensed Premises to Licensor. In such event, Licensor shall have the immediate right to re-enter and
remove all persons and property from the Licensed Premises and Shared Premises, and such property may be removed and stored in a public
warehouse or elsewhere at the cost and for the account of Licensee, without being deemed guilty of trespass or becoming liable for any
loss or damage that may be occasioned thereby. In the event that Licensor shall elect to so terminate this License, then Licensor shall
be entitled to recover from Licensee all direct and indirect damages incurred by Licensor by reason of Licensee’s default, including,
but not limited to, recovery of any broker’s fee paid by Licensor in relation to this Agreement and all reasonable attorneys’
fees. Upon termination of this Agreement, the License shall expire and Licensee shall immediately vacate the Licensed Premises and Shared
Premises. Under no circumstances shall Licensor or Landlord be liable for any alleged, purported, consequential or indirect damages resulting
from Licensor or Landlord terminating this Agreement. Notwithstanding anything to the contrary contained herein, except as expressly set
forth in Section 8 and in the event of damages stemming from hold over after termination of this Agreement, in no other case shall
Licensee be liable under this Agreement for any lost profits, damage to business or any form of special, indirect, punitive or consequential
damages.

		3.	License Fee.

 

		(a)	Base Fee. Commencing on the first full month after the Term Commencement Date (“License
Fee Commencement Date”), Licensee shall pay a monthly license fee equal to $367,159.00 (“License Fee”), plus
any pro rata portion thereof if the Term Commencement Date is any date other than the first of the month, which Licensee shall pay in
advance on or before the first day of each and every month during the Term by electronic payment to Licensor. The License Fee shall be
subject to a three percent (3%) increase upon each anniversary of the License Fee Commencement Date.

 

		(b)	Late Fee. If any payment of the License Fee, or any other payment due under this Agreement, is
not received by Licensor no later than the second (2nd) business day of each month, or when otherwise due, Licensee shall pay to Licensor
a late payment charge equal to five percent (5%) of the amount of such delinquent payment, in addition to any outstanding License Fee
or any other payment due under this Agreement then owing; provided, however, Licensor hereby agrees to waive one such late fee in any
twelve (12) month period so long as Licensee shall pay such outstanding amounts within five (5) days of written notice from Licensor
to Licensee of such late payment. Licensee shall pay twelve percent (12%) interest per annum on any outstanding License Fee or other payment
due under this Agreement that remains unpaid; such interest shall accrue beginning the date such payment is due until the date such payment
is actually paid.

 

		(c)	Additional Fees. Licensee may request that Licensor grant access to Additional Occupants provided
that Licensee first (i) submits a written request to Licensor requesting Additional Occupants; (ii) Licensee receives written
confirmation from Licensor granting access to Additional Occupants (which Licensor may withhold in its sole discretion); and (iii) Licensee
pays, in addition to the License Fee, an amount equal to $2,500 per month for each Additional Occupant.

 

    	 	4	 

     

    

 

		(d)	Security Deposit. Licensee shall to pay a Security
Deposit equal to $413,240.69 (“Security Deposit”). The purpose of the Security Deposit is to guarantee the full,
prompt and faithful performance by Licensee of all of the terms, conditions, covenants, agreements, warranties and provisions of this
Agreement to be performed, fulfilled or observed by Licensee hereunder, including but not limited to the payment of the License Fee and
other charges. If Licensee breaches any term or condition of this Agreement, beyond applicable notice and cure periods, said Security
Deposit or any part thereof may be used to pay any such payment or perform any obligations of the Licensee, and the Licensee shall immediately
replace the amount of the Security Deposit so used. Said Security Deposit may be co-mingled with the Licensor’s other funds, need
not be kept in a separate account, and Licensor shall not be required to pay interest on same. Licensor shall return the balance of the
Security Deposit within thirty (30) days following the end of Term, as extended from time to time. Licensor, from time to time, may transfer
the Security Deposit to any mortgagee or any grantee or grantees to be held by such mortgagee, grantee or grantees as the Security Deposit
hereunder on the above terms, and upon such transfer to such mortgagee, grantee or grantees, Licensor thereupon shall be relieved from
all further liability to the Licensee with respect to the Security Deposit, and Licensee thereafter shall look only to such mortgagee,
grantee or grantees for the return of the Security Deposit.

 

		(e)	Initial Payment. Licensee shall pay, immediately upon executing this Agreement, an amount equal
to the License Fee for the first three months of the Term of this Agreement ($1,101,477.00), the Security Deposit ($413,240.69), and the
Parking Fees (as defined below) associated with Licensee’s Parking Spaces (as defined below). As such, Licensee shall pay a total
of $1,514,717.69, plus the aforementioned Parking Fees, as of the execution of this Agreement.

 

		4.	Service Agreement. Licensor agrees to provide to Licensee, during the entire Term of this Agreement,
the services set forth in the Service Agreement attached hereto as Exhibit 2. The License Fee shall cover and include the
cost of the services set forth in the Service Agreement and, unless the scope of services requested by Licensee exceed those set forth
in the Service Agreement, Licensee shall not be assessed any additional fees for services contained in the Service Agreement. The Service
Agreement shall be governed by the terms of this Agreement and if there is any conflict between the covenants and representations contained
in this Agreement and the Service Agreement, the terms of this Agreement shall prevail and be binding upon Licensor and Licensee. Licensor
shall not be liable for any failure to provide the services set forth in the Service Agreement to the extent such failure is beyond Licensor’s
reasonable control. Notwithstanding the foregoing to the contrary, if, due to any gross negligent or willful and wrongful act of Licensor,
there is an interruption of one or more services or utilities that Licensor is obligated to perform or deliver under this Agreement, and
such interruption of services or utilities renders the Licensed Premises untenantable (meaning that either (x) electric service to
the Licensed Premises has been interrupted or (y) any other service or utility to the Licensed Premises is interrupted and Licensee
is unable to reasonably use the Licensed Premises for the conduct of Licensee’s business and, as a result thereof, Licensee has
in fact ceased use of the Licensed Premises or portion thereof for the conduct of Licensee’s business), and if such interruption
shall continue for a period of five (5) consecutive business days after notice thereof from Licensee to Licensor that the Licensed
Premises are untenantable as a result thereof, then License Fee, together with Licensee’s payments on account of the Parking Fees
and any additional fees related to Additional Occupant(s) shall equitably abate, based upon the degree of interference with Licensee’s
ongoing business, commencing on the sixth business day after such notice (and, if less than all of the Licensed Premises are made untenantable,
such abatement shall be pro-rated according to the area made untenantable) until such time as such services and/or utilities are restored.
Licensor shall use due diligence to cause such restoration of the interruption at the soonest reasonable time. Licensee’s abatement
rights herein granted shall be Licensee’s sole and exclusive remedies for any loss or damage arising from any such interruption.

 

    	 	5	 

     

    

 

		5.	Common Areas. Licensee hereby acknowledges that other licensees and/or occupants are occupying
or may in the future occupy other portions of the Building. Licensee’s use of the Licensed Premises, and access to and use of the
common areas and any other services in connection with the Licensed Premises or this Agreement, shall be subject to any and all rules and
procedures reasonably promulgated by Licensor and/or Landlord and delivered to Licensee from time to time; provided, however, in the event
of a conflict between the terms and conditions of those rules and regulations and this Agreement, this Agreement shall control. Licensee’s
compliance with such rules and procedures constitutes a material inducement to Licensor’s willingness to enter into this Agreement;
any violation thereof shall constitute a material breach of this Agreement.

 

		6.	Parking. During the Term, Licensee shall have a non-exclusive, irrevocable license to use at least
twelve (12) unreserved parking spaces in the area adjacent to the Building (“Licensee’s Parking Spaces”). Licensee
shall have no right to elect to reduce its number of Licensee’s Parking Spaces and shall be responsible for the Parking Fees (defined
below) for such spaces regardless of whether its Occupants use Licensee’s Parking Spaces. Licensee shall pay, in addition to the
License Fee, monthly parking fees equal to the prevailing rates for the Building at no markup by Licensor (“Parking Fees”)
and shall pay such Parking Fees to Licensor at the time each License Fee payment is due. Upon Licensee’s written request within
the first eighteen (18) months of the Term, additional parking of up to fifteen (15) parking spaces may be available and is subject to
Licensor’s discretion and terms (provided, however, in no event shall Licensor be entitled to a markup of any parking fees). Parking
Fees are subject to change. For the avoidance of doubt, Licensee shall be entitled to contract for additional parking spaces directly
with the Landlord or other third party provider without affecting Licensee’s right to the Licensee’s Parking Spaces in accordance
with this Section 6.

 

		7.	Modifications to Licensed Premises. Licensee shall not make any modification to the Licensed Premises
without Licensor’s prior written approval, which approval may be withheld or conditioned in Licensor’s sole discretion. Following
the initial improvements of the space, Licensee shall bear the cost of any approved modifications to the Licensed Premises completed by
or on behalf of Licensee. All articles of personal property, and all business and trade fixtures, machinery and equipment, cabinet work,
furniture and movable partitions, if any, paid for or installed by Licensee in the Licensed Premises will be and remain the property of
Licensee and may be removed by Licensee at any time, provided that Licensee, at its expense, shall repair any damage to the Licensed Premises
caused by such removal or by the original installation. Licensee shall remove all of Licensee’s personal property at the expiration
of the Term of this Agreement or sooner termination of this Agreement, in which event the removal shall be done at Licensee’s expense
and Licensee, prior to the end of the Term of this Agreement or upon sooner termination of this Agreement, shall repair any damage to
the Licensed Premises caused by its removal.

 

    	 	6	 

     

    

 

Licensor shall, at its expense, provide
Licensee with building standard lobby and directory signage. Licensor shall use best efforts to assist Licensee to gain permission from
the Landlord to display window signage, which shall be at Licensee’s expense. Licensee understands that the Lease has specific criteria
and requirements with respect to signage and therefore any signage approvals must be made by Landlord, which Landlord may withhold in
its sole discretion. Nothing contained herein shall be interpreted as a promise or agreement that Licensee may display any signage beyond
building standard lobby and directory signage.

 

		8.	Hazardous Materials. Licensee shall strictly comply with any and all Hazardous Materials provisions
contained in Section 29.11 of the Lease, attached hereto as Exhibit 5. Licensee shall strictly comply with all Environmental
Laws to the extent such provisions relate to the Licensed Premises during the Term of this Agreement. For purposes hereof, “Environmental
Laws” shall mean all laws, statutes, ordinances, rules and regulations of any local, state or federal governmental authority
having jurisdiction concerning environmental, health and safety matters, including but not limited to any discharge by Licensee or Licensee’s
Occupants into the air, surface water, sewers, soil or groundwater of any Hazardous Material (defined below) whether within or outside
the Licensed Premises, including, without limitation (i) the Federal Water Pollution Control Act, 33 U.S.C. Section 1251 et
seq., (ii) the Federal Resource Conservation and Recovery Act, 42 U.S.C. Section 6901 et seq., (iii) the Comprehensive
Environmental Response, Compensation and Liability Act, 42 U.S.C. Section 9601 et seq., (iv) the Toxic Substances Control Act
of 1976, 15 U.S.C. Section 2601 et seq., and (v) Chapter 21E of the General Laws of Massachusetts. Licensee, at its sole cost
and expense, shall comply with (a) Environmental Laws, and (b) any rules, requirements and safety procedures of the Massachusetts
Department of Environmental Protection, the city in which the Building is located, and any insurer of the Building or the Licensed Premises
with respect to Licensee’s use, storage and disposal of any Hazardous Materials. Notwithstanding anything in this Agreement to the
contrary, Licensee shall have no liability to Licensor or responsibility under this Agreement for any Hazardous Materials in, on, under
or about the Licensed Premises that were not released, discharged, stored or introduced by Licensee or its agents. Licensee understands
and agrees that Licensor must decontaminate the Licensed Premise prior to Licensee vacating same and therefore Licensee shall fully cooperate
with Licensor in the aforementioned decontamination, which may include Licensee ceasing its operations and/or removing personal property
prior to the expiration of the Term. The term “Hazardous Material” means asbestos, oil or any hazardous, radioactive
or toxic substance, material, waste or petroleum derivative which is or becomes regulated by any Environmental Law or which is designated
as a “hazardous substance,” “hazardous material,” “oil,” “hazardous waste” or toxic substance
under any Environmental Law. Licensee shall follow all of Licensor’s Environmental Health and Safety (“EH&S”)
guidelines and requirements, which may be modified from time to time.

		9.	Fire, Other Casualty; Eminent Domain. In the event of a fire or other casualty affecting the Building
or the Licensed Premises, or a taking of all or a part of the Building or Licensed Premises under the power of eminent domain: (i) Licensor
shall not have any obligation to repair or restore the Licensed Premises, alterations or personal property; (ii) Licensee shall be
entitled only to a proportionate abatement of the License Fee (including any charges for Additional Occupant(s) and Parking Fees)
during the time and to the extent the Licensed Premises are unfit for the purposes permitted under this Agreement and not used by Licensee
as a result thereof; (iii) Licensee shall not, by reason thereof, have a right to terminate this Agreement unless the Lease shall
be terminated; and (iv) Licensor and Landlord reserve the right to terminate this Agreement in connection with any right granted
to either Licensor or Landlord under the Lease whether or not the Licensed Premises is damaged or the subject of a taking. In the event
Licensor or Landlord exercises the right to terminate the Lease as the result of any such fire, casualty or taking, (a) Licensor
shall provide Licensee with a copy of the relevant termination notice and this Agreement shall terminate on the date upon which the Lease
terminates and (b) Licensee shall immediately pay to Licensor all of Licensee’s insurance proceeds relating to all alterations.
Notwithstanding anything to the contrary contained herein, in the event a casualty or condemnation proceeding occurs during the last twelve
(12) months of the Term resulting in the destruction or taking of all or a material portion of the Licensed Premises or access thereto,
Licensee and Licensor shall each have the right to terminate this Agreement upon thirty (30) days prior written notice to the other, with
such notice to be given within thirty (30) days following the casualty or condemnation event.

 

		10.	Limit of Liability. Notwithstanding anything to the contrary contained in this Agreement, Landlord,
Licensor, their respective, members, officers, directors, employees, agents, servants, lenders, mortgagees, ground lessors beneficiaries
and contractors (collectively, the “Licensor Parties”), shall not be liable for any damages or injury to person or
property or resulting from the loss of use thereof sustained by Licensee or anyone having claims through or on behalf of Licensee, based
on, arising out of, or resulting from, any cause whatsoever, including any due to the Building becoming out of repair, or due to the occurrence
of any accident or event in or about the Building, or due to any act or neglect of any tenant or occupant of the Building or any other
person. Notwithstanding the foregoing provision of this Section, Licensor Parties shall not be released from liability to Licensee for
any physical injury to any natural person caused by Licensor Parties’ gross negligence or willful misconduct to the extent such
injury is not covered by insurance either carried by Licensee (or such person) or required by this Agreement to be carried by Licensee;
provided that Licensor Parties shall not, under any circumstances, be liable for any exemplary, punitive, consequential or indirect damages
(or for any interruption of or loss to business). No Licensor Parties’ shall be held to have any personal liability for satisfaction
or any claim or judgment.

 

    	 	8	 

     

    

 

		11.	Waiver of Claims. Licensee hereby releases and waives any and all claims against the Licensor Parties
for injury or damage to person, property or business of every kind, nature and description, sustained in or about the Building or the
Licensed Premises by Licensee or anyone claiming under Licensee, other than by reason of gross negligence or willful misconduct of the
Licensor Parties and except in any case which would render this release and waiver void under applicable law.

 

		12.	Insurance. See Insurance Requirements attached hereto as Exhibit 3.

 

		(a)	Subrogation. Licensee and its insurers hereby waive any and all rights of recovery or subrogation
against the Licensor Parties with respect to any Claims (as defined below) howsoever caused, that are covered or should have been covered,
by valid and collectible insurance, including any deductibles or self-insurance maintained thereunder. If necessary, Licensee shall endorse
the required insurance policies to permit waivers of subrogation as required hereunder and hold harmless and indemnify the Licensor Parties
for any loss or expense incurred as a result of a failure to obtain such waivers of subrogation from insurers. Such waivers shall continue
so long as Licensee’s insurers so permit. Any termination of such a waiver shall be by written notice to Licensor. Licensee, upon
obtaining the policies of insurance required or permitted hereunder, shall give notice to its insurance carriers that the foregoing waiver
of subrogation is contained in herein. If such policies shall not be obtainable with such waiver or shall be so obtainable only at a premium
over that chargeable without such waiver, then Licensee shall notify Licensor of such conditions. Licensor and its insurers hereby waive
any and all rights of recovery or subrogation against the Licensee with respect to any Claims (as defined below) howsoever caused, that
are covered, or should have been covered, by valid and collectible insurance, including any deductibles or self-insurance maintained thereunder.
If necessary, Licensor agrees to endorse the required insurance policies to permit waivers of subrogation as required hereunder and hold
harmless and indemnify the Licensee for any loss or expense incurred as a result of a failure to obtain such waivers of subrogation from
insurers. Such waivers shall continue so long as Licensor’s insurers so permit. Any termination of such a waiver shall be by written
notice to Licensee. If such policies shall not be obtainable with such waiver or shall be so obtainable only at a premium over that chargeable
without such waiver, then Licensor shall notify Licensee of such conditions.

 

		(b)	Assumption of Risk. Licensee assumes the risk of damage, and shall be liable for any damage caused
to, any fixtures, goods, inventory, merchandise, equipment and leasehold improvements, and the Licensor Parties shall not be liable for
injury to Licensee’s business or any loss of income therefrom, relative to such damage. Licensee shall, at Licensee’s sole
cost and expense, carry such insurance as Licensee desires for Licensee’s protection with respect to personal property of Licensee
or business interruption.

 

    	 	9	 

     

    

 

		13.	Indemnification. Except to the extent the same is solely the result of the gross negligence or
willful misconduct of Licensor or any of the Licensor Parties, and subject to the waiver of subrogation contained in Section 12 hereof,
Licensee shall indemnify, defend (by counsel acceptable to Licensor), release, protect and hold the Licensor Parties harmless from and
against any and all demands, claims, liabilities, losses, costs, expenses, actions, causes of action, damages, suits or judgments, and
all reasonable expenses (including reasonable attorneys’ fees, charges and disbursements, regardless of whether the applicable demand,
claim, action, cause of action or suit is voluntarily withdrawn or dismissed) incurred in investigating or resisting the same (collectively,

this Agreement or the Lease, including, without limitation, Licensee’s obligation to surrender the Licensed Premises in the condition
herein required; (iii) the negligence or willful misconduct of Licensee, its agents or anyone claiming by, through or under Licensee;

recklessness or willful misconduct of Licensee or its agents.

 

		14.	Assignment. Licensee shall not assign, encumber or transfer this Agreement, or any part of it,
or its right or interest in it, without Licensor’s prior written approval, with such approval not to be unreasonably withheld, conditioned
or delayed. Licensee shall not in any way obstruct or interfere with the rights of other licensees, occupants or users of the Building,
nor shall it permit its employees, representatives, or contractors to do so. Licensor may assign this Agreement.

 

If Licensee is a corporation, limited
liability company, partnership or trust, the transfer of outstanding capital stock of Licensee by persons or parties through the “over
the counter market” or through any recognized stock exchange, shall not be deemed an assignment or transfer of this Agreement.

 

Notwithstanding anything to the contrary

in connection with,) the following transfers: (1) transfers to an entity into or with which Licensee is merged or consolidated, or
(2) transfers to any entity which purchases all or substantially all of Licensee’s voting stock, partnership interests or other
membership interests, or (3) transfers to an entity to which all or substantially all of Licensee’s assets are transferred

(including, without limitation, subleases or other occupancy agreements) to any entity which controls or is controlled by Licensee or
is under common control with Licensee (the transferee in clause (4) being referred to as a “Licensee Affiliate”); provided
however, Licensee shall provide thirty (30) day advance written notice to Licensor prior to any such transfer and, further provided that
in any of such events:

 

(i)          with
respect to a Licensee Successor such Licensee Successor has a net worth which, in Licensor’s reasonable judgment, is sufficient
to meet the financial and other obligations of Licensee under this Agreement;

EIGHTEENTH SUPPLEMENTAL INDENTURE

 

EIGHTEENTH SUPPLEMENTAL INDENTURE
(this “Supplemental Indenture”), dated as of October 7, 2021, among Marsh Landing Holdco LLC (the “Guaranteeing
Subsidiary”), a subsidiary of Clearway Energy Operating LLC (or its permitted successor), a Delaware limited liability company
(the “Company”), the Company, the other Guarantors (as defined in the Indenture referred to herein) and Delaware Trust
Company (as successor in interest to Law Debenture Trust Company of New York), as trustee under the Indenture referred to below (the “Trustee”).

 

W I T N E S S E T H

 

WHEREAS, the Company has heretofore
executed and delivered to the Trustee an indenture (the “Indenture”), dated as of August 18, 2016 providing for
the issuance of 5.000% Senior Notes due 2026 (the “Notes”);

 

WHEREAS, the Indenture provides
that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant
to which the Guaranteeing Subsidiary shall fully and unconditionally guarantee all of the Company’s Obligations under the Notes
and the Indenture on the terms and conditions set forth herein (the “Subsidiary Guarantee”); and

 

WHEREAS, pursuant to Sections
4.10 and 9.01 of the Indenture, the Trustee, the Company and the other Guarantors are authorized to execute and deliver this Supplemental
Indenture.

 

NOW, THEREFORE, in consideration
of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary
and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

 

1.            CAPITALIZED
TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

 

2.            AGREEMENT
TO GUARANTEE. The Guaranteeing Subsidiary hereby becomes a party to the Indenture as a Guarantor and as such will have all the rights
and be subject to all the Obligations and agreements of Guarantors under the Indenture. The Guaranteeing Subsidiary hereby agrees to provide
a full and unconditional Guarantee on the terms and subject to the conditions set forth in the Subsidiary Guarantee and in the Indenture
including but not limited to Article 10 thereof.

 

3.            NO
RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of the Company or any Guarantor, as such, will have
any liability for any obligations of the Company or the Guarantors under the Notes, this Indenture, the Subsidiary Guarantees or for any
claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and
releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective
to waive liabilities under the federal securities laws.

 

    

     

    

 

4.            NEW
YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD
BE REQUIRED THEREBY.

 

5.            COUNTERPARTS.
The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together
represent the same agreement.

 

6.            EFFECT
OF HEADINGS. The Section headings herein are for convenience only and shall not affect the construction hereof.

 

7.            THE
TRUSTEE. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary
and the Company.

 

8.            RATIFICATION
OF INDENTURE; SUPPLEMENTAL INDENTURE FOR ADDITIONAL GUARANTEES PART OF INDENTURE. Except as expressly amended hereby, the Indenture
is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect.
This Supplemental Indenture for Additional Guarantees shall form a part of the Indenture for all purposes, and every Holder of Notes heretofore
or hereafter authenticated and delivered shall by bound hereby.

 

9.            ELECTRONIC
SIGNATURES. Each of the transaction parties agrees on behalf of itself, and any Person acting or claiming by, under or through such transaction
party, that any written instrument delivered in connection with this Supplemental Indenture, the Indenture or any related document, including
without limitation any amendments or supplements to such documents, may be executed by electronic methods (whether by .pdf scan or utilization
of an electronic signature platform or application). Any electronic signature document delivered via email from an Officer of the Company,
any Guaranteeing Subsidiary or any other Guarantor to the Trustee shall be considered signed or executed by such person on behalf of the
Company, such Guaranteeing Subsidiary, or such other Guarantor, as applicable. Each of the Company, the Guaranteeing Subsidiary, and the
other Guarantors agree to assume all risks arising out of the use of electronic methods for all purposes including the authorization,
execution, delivery, or submission of documents, instruments, notices, directions, instructions, reports, opinions and certificates to
the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk of interception and
misuse by third parties. Any electronic signature shall have the same legal validity and enforceability as a manually executed signature
to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the
New York State Electronic Signatures and Records Act, or any similar federal or state law, rule or regulation, as the same may be
in effect from time to time, and the parties hereby waive any objection to the contrary. Any document accepted, executed or agreed to
in conformity with such laws will be binding on all parties hereto to the same extent as if it were physically executed and each party
hereby consents to the use of any third party electronic signature capture service providers as may be reasonably chosen by a signatory
hereto.
